("AAMI") is investment adviser to the AmSouth Funds and a wholly-owned subsidiary of AmSouth Bank, which in turn is wholly owned by AmSouth Bancorporation. AmSouth Bank and AAMI have determined that engaging in the business of investment adviser to the AmSouth Funds is not a core business that AAMI intends to continue. After investigating and discussing several alternatives for ongoing investment management of the AmSouth Funds with the Trustees, AmSouth Bank and AAMI conducted a search for a buyer for AAMI's fund management business. 4 Ultimately, AmSouth Bank and AAMI decided to recommend to the Board that the AmSouth Funds be reorganized into similar mutual funds managed by Pioneer Investment Management, Inc. ("Pioneer"). The Board met twice in May 2005 and again in June 2005. At these meetings, your Trustees received and evaluated materials regarding Pioneer and the Pioneer Funds, including the performance record and expense structure of each of the Pioneer Funds, the impact of the proposed Reorganizations on the AmSouth Funds' shareholders, and the quality of the services offered by Pioneer. The Trustees also considered other alternatives for the ongoing management of AmSouth Funds. At a meeting on May 18, 2005, the Trustees met with representatives of Pioneer. In addition to these general factors, the Trustees also considered the factors discussed below in the context of each Reorganization. At the May 18, 2005 meeting, all of the Trustees who are not interested persons of AAMI (the "Independent Trustees") met separately in executive session with counsel to the Independent Trustees and requested and received such information from AAMI and Pioneer as they determined to be necessary and appropriate to evaluate the proposed Reorganizations. On June 23, 2005, the Board, including all of the Independent Trustees, unanimously voted to approve each of the Reorganizations. In approving the Reorganizations, the Board determined that the Reorganizations were in the best interests of the AmSouth Funds' shareholders and the interests of existing AmSouth Funds' shareholders will not be diluted as a result of the Reorganizations. Pioneer believes that it can offer capable management and favorable long-term investment performance to the AmSouth Funds' shareholders. The Reorganizations will, by combining the assets of two mutual funds and by increasing distribution capabilities, offer the potential for increased economies of scale. Increased economies of scale have the potential of benefiting the shareholders of your AmSouth Funds and the Pioneer Funds by spreading fixed costs over a larger asset base and reducing expenses on a per share basis. There can be no assurance that such economies of scale will be realized. Why the Trustees Are Recommending the Reorganizations The Trustees believe that reorganizing your AmSouth Fund into a portfolio with a substantially similar investment objective and similar investment policies that is part of the Pioneer family of funds offers you potential benefits. These potential benefits and considerations include: o AmSouth Bank and AAMI have determined that engaging in the business of investment adviser to the AmSouth Funds is not a core business that AAMI intends to continue. Therefore, a change in your AmSouth Fund's investment adviser is necessary. In the absence of the Reorganization, such change would be more likely to motivate shareholders invested in reliance on AAMI's role to withdraw from the Fund, thereby reducing the fund size and increasing fund expense ratios; o The track record of Pioneer in managing the Pioneer Funds; 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 there fore will not be treated as a taxable sale of your AmSouth shares; o In the case of certain AmSouth Funds, the potential for lower management fees and total expenses; o The resources of Pioneer, including its infrastructure in shareholder services; and o The opportunity to be part of a significantly larger family of funds, with additional product offerings and enhanced shareholder servicing options, and a stronger compliance structure. For further information, please see the individual descriptions of the proposals contained in this Proxy Statement/Prospectus. How Each Reorganization Will Work o AmSouth Fund shareholder-directed exchanges and purchases made by check, [ACH], or wire will be accepted up until [ ] [a/p].m. ([ ] Time) on [ ]day, [ ], 2005. Exchange and purchase requests received after this deadline will be rejected and returned. Purchase and exchange requests made by AmSouth Fund shareholders through financial institutions or advisers must be made earlier to ensure the trade can be processed within this deadline. Financial institutions and advisers that trade electronically (NSCC) with the AmSouth Funds can place exchange and purchase requests up until [ ] [a/p].m. ([ ] Time) on [ ]day, [ ], 2005. Exchanges and purchases received after this deadline will be rejected and returned. The AmSouth Funds will not process purchases made via automatic investment method (AIM) after [ ], 2005. Dividend/capital gain reinvestment and established systematic exchanges will continue through [ ], 2005. 5 o Each AmSouth Fund will transfer all of its assets to a corresponding Pioneer Fund. Each Pioneer Fund will assume the corresponding AmSouth Fund's liabilities that are included in the calculation of such AmSouth Fund's net asset value on the day on which each Reorganization closes (the "Closing Date"). Liabilities of each Fund to its shareholders not assumed by a corresponding Pioneer Fund will be assumed by AmSouth Bancorporation. o Each Pioneer Fund will issue Class A, B and Y shares to the corresponding AmSouth Fund in amounts equal to the aggregate net asset value of that AmSouth Fund's Class A, B and I shares. Shareholders of your AmSouth Fund will receive Class A, B and Y shares of the corresponding Pioneer Fund. 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 Pioneer Fund with the same aggregate net asset value as the shares of the AmSouth Fund that the shareholder held immediately prior to the Reorganization. o Each AmSouth Fund will be dissolved after the Closing Date. o Pioneer acts as investment adviser to each Pioneer Fund. o The Reorganizations are intended to result in no income, gain or loss being recognized for federal income tax purposes to any of the Pioneer Funds, the AmSouth Funds or the shareholders of the AmSouth Funds. o In recommending each of the Reorganizations, the Trustees of your AmSouth Fund have determined that the Reorganization is in the best interest of your AmSouth Fund and will not dilute the interests of shareholders of your AmSouth Fund. The Trustees have made that determination on the basis of the factors listed above and discussed in more detail under each proposal. A reorganization might not be in the best interest of the shareholders of a mutual fund if the surviving fund had higher expenses, less experienced management or the adviser did not have adequate resources to manage the affairs of the mutual fund. o If the Reorganizations are approved, the AmSouth Funds will file with the SEC an application for deregistration on Form N-8F under the Investment Company Act of 1940, as amended (the "Investment Company Act"), and will cease to exist as an investment company when such application is approved. Who Is Pioneer Pioneer is registered as an investment adviser under the Investment Advisers Act of 1940, as amended, and acts as investment adviser to mutual funds and institutional accounts. Pioneer or its predecessors have been managing mutual funds since 1928 and at December 31, 2004 had, together with its affiliates, over $42 billion in assets under management. Pioneer is an indirect, wholly owned subsidiary of UniCredito Italiano S.p.A., an Italian Bank. In addition to the Class A, B and Y shares to be issued in the Reorganization, each Pioneer Fund also offers Class C shares (subject to a contingent deferred sales charge and a Rule 12b-1 Plan). In addition, most of the Pioneer Funds also offer Class R shares (which are offered only to certain retirement plans). Who Bears the Expenses Associated with the Reorganizations Pioneer and AmSouth Bancorporation will pay all costs of preparing and printing the AmSouth Funds' proxy statements and solicitation costs incurred by the AmSouth Funds in connection with the Reorganization. AAMI will otherwise be responsible for all costs and expenses of the AmSouth Funds in connection with the Reorganizations. Will Pioneer and AmSouth Bancorporation Benefit from the Reorganizations Pioneer will benefit from managing a larger pool of assets. Pioneer is also acquiring certain assets associated with AAMI's fund management business and the benefits of certain restrictive covenants on AAMI's and AmSouth Bancorporation's activities. In consideration for the acquisition of these assets, the opportunity to manage additional assets and covenants from AmSouth Bancorporation and AAMI, including their assistance in facilitating the Reorganizations, noncompetition covenants and their obligation to indemnify Pioneer against certain liabilities, Pioneer has agreed to pay AAMI $65 million. This amount is subject to partial repayment in the event that the assets attributable to the AmSouth Funds are 6 redeemed (subject to certain conditions, including threshold amounts) from the Pioneer Funds within four years after the closing of the Reorganization. Pioneer will also agree to provide an affiliate of AAMI with ongoing servicing payments with respect to the Class Y shares issued in the Reorganizations. This additional compensation will be equal on an annual basis to 0.10% of the average daily net assets attributable to the Class Y shares held by former AmSouth Funds' shareholders. This payment would be made by Pioneer and not the Pioneer Funds. No additional compensation would be paid with respect to Class A or Class B shares; however, if an affiliate of AAMI is the broker of record, that affiliate would receive the trail commissions under the Class A and Class B Rule 12 b-1 Plans. What Happens if a Reorganization Is Not Approved If the required approval of shareholders is not obtained, the Meeting may be adjourned as more fully described in this Proxy Statement/Prospectus, your AmSouth Fund will continue to engage in business as a separate mutual fund and the Board will consider what further action may be appropriate. Who Is Eligible to Vote Shareholders of record on [ ], 2005 are entitled to attend and vote at the Meeting or any adjournment of the Meeting. On each proposal, all shareholders of an AmSouth Fund, regardless of the class of shares held, will vote together as a singe class. 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. 7 TABLE OF CONTENTS Page ---- INTRODUCTION..............................................................................

You could lose money on your investment in either Fund or not make as much as if you invested elsewhere if: 8 o The stock market goes down (this risk may be greater in the short term) o Large company or growth stocks fall out of favor with investors o The adviser's/subadviser's judgment about the attractiveness, growth potential or potential appreciation of a particular stock proves to be incorrect Pioneer Oak Ridge Large Cap Growth Fund may be subject to the following additional risks associated with investing in non-U.S. issuers, which may involve unique risks compared to investing in securities of U.S. issuers. These risks are more pronounced to the extent the Fund invests in issuers in countries with emerging markets or if the Fund invests significantly in one 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, the adviser/subadviser might 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 In addition, at times, more than 25% of Pioneer Oak Ridge Large Cap Growth Fund's assets may be invested in the same market segment, such as financial or technology. To the extent the Fund emphasizes 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. AmSouth Capital Growth Fund is subject to risks relating to the fact that it is non-diversified. The Fund may invest in a small number of companies which may increase the volatility of the Fund. Accordingly, the Fund's portfolio may be more sensitive to changes in the market value of a single company or industry. Although Pioneer Oak Ridge Large Cap Growth Fund is classified as a diversified investment company, the Fund's portfolio may be comprised of fewer issuers than many large cap growth funds. Typically, the subadviser expects the portfolio to include a limited number of different issuers, which may increase the volatility of the Fund's net asset value per share. Past Performance Set forth below is performance information for each Fund. The bar charts show how each Fund's total return (not including any deduction for sales charges) has varied from year to year for each full calendar year. The tables show average annual total return (before and after 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 bar charts give an indication of the risks of investing in each Fund, including the fact that you could incur a loss and experience volatility of returns year to year. Past performance before and after taxes does not indicate future results. 9 AmSouth Capital Growth Fund -- Class A Shares Calendar Year Total Returns* [THE FOLLOWING DATA WAS REPRESENTED AS A BAR CHART IN THE PRINTED MATERIAL] 1995 1996 1997 1998 1999 2000 2001 2002 2003 2004 30.42 22.25 30.79 32.05 21.85 -0.69 -21.75 -25.17 26.36 3.80 * During the period shown in the bar chart, your AmSouth Fund's highest quarterly return was 22.63% for the quarter ended December 31, 1998, and the lowest quarterly return was -21.26% for the quarter ended September 30, 2001.

The ISG Capital Growth Fund commenced operations on 4/1/96 through a transfer of assets from certain collective trust fund ("commingled") accounts managed by First American National Bank, using substantially the same investment objective, policies and methodologies as the Fund. The quoted before-tax returns of the Fund includes the performance of the predecessor fund and commingled accounts for periods dating back to 7/31/93, and prior to the Fund's commencement of operations, restated to reflect the expenses associated with the Fund. The commingled accounts were not registered with the SEC and, therefore, were not subject to the investment restrictions imposed by law on registered mutual funds. If the commingled accounts had been registered, the commingled accounts' performance may have been adversely affected. After-tax returns reflect performance since 4/1/96, and do not include the performance of the commingled accounts prior to that date. Class A shares were first offered on 4/1/96. (2) Performance for the Class B shares, which were first offered on 2/5/98, is based on the historical performance of the Fund's Class A shares, including the performance of the predecessor fund and commingled accounts (without sales charge), prior to that date. The predecessor fund and commingled accounts were managed using substantially the same investment objective, policies and methodologies as the Fund. The historical performance of the Class B shares has been restated to reflect the Fund's Class B shares distribution (12b-1) fees and the contingent deferred sales charge. (3) Performance for the Class I shares, which were first offered on 10/3/97, is based on the historical performance of the Fund's Class A shares, including the performance of the predecessor fund and commingled accounts (without sales charge), prior to that date. The predecessor fund and commingled accounts were managed using substantially the same investment objective, policies and methodologies as the Fund. (4) The S&P 500/Barra Growth Index, an unmanaged index of 500 stocks, is for reference only, does not mirror the Fund's investments, and reflects no deduction for fees, expenses or taxes. The table above shows the impact of taxes on AmSouth Capital Growth Fund's returns. After-tax returns are only shown for Class A shares and Class I shares and may vary for Class B shares. The Fund's after-tax returns are calculated using the highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. In certain cases, the figure representing "Return After Taxes on Distributions and Sale of Fund Shares" may be higher than the other return figures for the same period. A higher after-tax return results when a capital loss occurs upon redemption and translates into an assumed tax deduction that benefits the shareholder. Please note that actual after-tax returns depend on an investor's tax situation and may differ from those shown. Also note that 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. The Pioneer Fund's past performance does not necessarily indicate how it will perform in the future. Pursuant to an agreement and plan of reorganization, the Pioneer Fund acquired all of the assets and those liabilities reflected in the net assets of Oak Ridge Large Cap Equity Fund (the predecessor fund) on February 13, 2004. In the reorganization, the predecessor fund exchanged all of its assets for Class A shares of the Pioneer Fund. The predecessor fund offered only one class of shares which 11 was most similar to Class A shares of the Pioneer Fund. As a result of the reorganization, the Pioneer Fund is the accounting successor of the predecessor fund, which commenced operations on March 1, 1999. The Pioneer Fund's subadviser served as the predecessor fund's investment adviser. The performance of each class of the Pioneer Fund includes the performance of the predecessor fund's shares prior to the reorganization, which has been restated to reflect differences in any applicable sales charges and Rule 12b-1 fees (but not other differences in expenses). This adjustment had the effect of reducing the previously reported performance of the predecessor fund.

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 the AmSouth Capital Growth Fund, the expenses of AmSouth Capital Growth Fund for the period ended January 31, 2005 and (ii) for Pioneer Oak Ridge Large Cap Growth Fund, the expenses of Pioneer Oak Ridge Large Cap Growth Fund for the period ended May 31, 2005. Future expenses for all share classes may be greater or less. Shareholders of AmSouth Large Cap Fund are also being asked to approve the reorganization of their fund into Pioneer Oak Ridge Large Cap Growth Fund. The tables also show (1) the pro forma expenses of the combined Fund assuming the Reorganization occurred on May 31, 2005, and (2) the pro forma expenses of the combined Fund assuming the reorganization of AmSouth Large Cap Fund into Pioneer Oak Ridge Large Cap Growth Fund also occurred on May 31, 2005. -

(2) Sales charges may be reduced depending upon the amount invested or, in certain circumstances, waived. Class A shares of the Pioneer Fund bought as part of an investment of $1 million or more are not subject to an initial sales charge, but may be charged a CDSC of 1.00% if sold within one year of purchase. (3) For Class B shares purchased prior to the combination of AmSouth Funds with ISG Funds, the CDSC on such Class B shares held continuously declines over six years, starting with year one and ending in year seven from: 4%, 3%, 3%, 2%, 2%, 1%. For all other Class B shares held continuously, the CDSC declines over six years, starting with year one and ending in year seven from: 5%, 4%, 3%, 3%, 2%, 1%. Eight years after purchase (seven years in the case of shares acquired in the ISG combination), Class B shares automatically convert to Class A shares. (4) To discourage short-term trading, a redemption fee of 2.00% will be charged on sales or exchanges of Class A, Class B and Class I shares of your AmSouth Fund made within 7 days of the date of purchase. A wire transfer fee of $7.00 will be deducted from the amount of your redemption if you request a wire transfer. (5) Other expenses for your AmSouth Fund are being limited to 0.49% for Class A shares, 0.49% for Class B shares and 0.34% for Class I shares. Any fee waiver or expense reimbursement arrangement is voluntary and may be discontinued at any time. (6) The Pioneer Fund's total annual operating expenses in the table have not been reduced by any expense offset arrangements. (7) The expenses in the table above reflect the expense limitations currently in effect for the Pioneer Fund, under which Pioneer has contractually agreed to limit ordinary operating expenses to the extent required to reduce fund expenses to 1.30%, and 2.20% of the average daily net assets attributable to Class A and Class B shares, respectively. These expense limitations are in effect through April 1, 2008 for Class A shares and through April 1, 2006 for Class B shares. There can be no assurance that Pioneer will extend the expense limitations beyond such time. (8) The expenses in the table above reflect the expense limitation in effect for Class B shares of the Pioneer Fund, under which Pioneer has contractually agreed to limit ordinary operating expenses to the extent required to reduce fund expenses 2.10% of the average daily net assets attributable Class B shares. This expense limitation is in effect through April 1, 2007. There can be no assurance that Pioneer will extend the expense limitations beyond such time. 14 The hypothetical example below helps you compare the cost of investing in each Fund. It assumes that: (a) you invest $10,000 in each Fund for the time periods shown, (b) you reinvest all dividends and distributions, (c) your investment has a 5% return each year, and (d) each Fund's gross operating expenses remain the same. The examples are for comparison purposes only and are not a representation of either Fund's actual expenses or returns, either past or future. - ------------------------------------------------------------------------------------------------------------ Combined Fund (including AmSouth Number of years you AmSouth Capital Pioneer Oak Ridge Large Combined Fund Large Cap Fund) own your shares Growth Fund Cap Growth Fund (Pro Forma) (Pro Forma) - ------------------------------------------------------------------------------------------------------------ Class A - ------------------------------------------------------------------------------------------------------------ Year 1 $682 $700 $695 $689 - ------------------------------------------------------------------------------------------------------------ Year 3 $960 $963 $949 $931 - ------------------------------------------------------------------------------------------------------------ Year 5 $1,259 $1,485 $1,222 $1,192 - ------------------------------------------------------------------------------------------------------------ Year 10 $2,106 $2,913 $1,999 $1,935 - ------------------------------------------------------------------------------------------------------------ Class B -- assuming redemption at end of period - ------------------------------------------------------------------------------------------------------------ Year 1 $725 $623 $613 $613 - ------------------------------------------------------------------------------------------------------------ Year 3 $994 $1,140 $995 $979 - ------------------------------------------------------------------------------------------------------------ Year 5 $1,390 $1,583 $1,304 $1,271 - ------------------------------------------------------------------------------------------------------------ Year 10 $2,340 $3,086 $2,342 $2,270 - ------------------------------------------------------------------------------------------------------------ Class B -- assuming no redemption - ------------------------------------------------------------------------------------------------------------ Year 1 $225 $223 $213 $213 - ------------------------------------------------------------------------------------------------------------ Year 3 $694 $840 $695 $679 - ------------------------------------------------------------------------------------------------------------ Year 5 $1,190 $1,483 $1,204 $1,171 - ------------------------------------------------------------------------------------------------------------ Year 10 $2,340 $3,086 $2,342 $2,270 - ------------------------------------------------------------------------------------------------------------ Class I Class Y - ------------------------------------------------------------------------------------------------------------ Year 1 $127 $121 $92 $88 - ------------------------------------------------------------------------------------------------------------ Year 3 $397 $378 $287 $274 - ------------------------------------------------------------------------------------------------------------ Year 5 $686 $654 $498 $477 - ------------------------------------------------------------------------------------------------------------ Year 10 $1,511 $1,443 $1,108 $1,061 - ------------------------------------------------------------------------------------------------------------ Reasons for the Proposed Reorganization The Trustees believe that the proposed Reorganization is in the best interests of AmSouth Capital Growth Fund and its shareholders. The Trustees considered the following matters, among others, in approving the proposal. First, AAMI, the investment adviser to your AmSouth Fund, informed the Trustees that it does not intend to continue to provide investment advisory services to the AmSouth Funds. Consequently, a change in your AmSouth Fund's investment adviser was necessary. In the absence of the Reorganization, such a change would be more likely to motivate shareholders invested in reliance on AAMI's role to withdraw from the Fund, thereby reducing fund size and increasing fund expense ratios. Second, the historical investment performance of Pioneer Oak Ridge Large Cap Growth Fund is significantly better than your AmSouth Fund's investment performance. For the one and five year periods ended December 31, 2004, Class A shares of Pioneer Oak Ridge Large Cap Growth Fund had an average annual return of 4.96% (one year); and -0.54% (five year), compared to an average annual return of the Class A shares of your AmSouth Fund of -1.94% (one year); and - -6.34% (five year), respectively, during the same period. In addition, the Trustees considered the track record of Pioneer in managing equity and fixed income mutual funds. 15 Third, the resources of Pioneer. At December 31, 2004, Pioneer managed over 80 investment companies and accounts with approximately $42 billion in assets, including $26.7 billion in equity securities. Pioneer is part of the global asset management group of UniCredito Italiano S.p.A., one of the largest banking groups in Italy, providing investment management and financial services to mutual funds, institutional and other clients. As of December 31, 2004, assets under management of UniCredito Italiano S.p.A. were approximately $175 billion worldwide. Shareholders of your AmSouth Fund would become part of a significantly larger family of funds that offers a more diverse array of investment options and enhanced shareholder account options. The Pioneer family of mutual funds offers over 80 funds, including domestic and international equity and fixed income funds and a money market fund that will be available to your AmSouth Fund's shareholders through exchanges Fourth, Pioneer Oak Ridge Large Cap Growth Fund's management fee (0.75% of average daily net assets) is lower than the advisory fee of your AmSouth Fund (0.80% of average daily net assets). The historical gross and net expenses of Pioneer Oak Ridge Large Cap Growth Fund attributable to Class A are slightly higher than your AmSouth Fund's historical gross and net expenses. However, the estimated pro forma expenses of the Pioneer Fund attributable to Class A and Y shares after giving effect to the Reorganizations on both a gross and net basis are lower than your AmSouth Fund's gross and net operating expenses for the Class A and I shares. The estimated pro forma expenses for Class B shares will be lower on a gross basis, but higher on a net basis. The Board considered the positive factors associated with the Reorganization, such as the superior performance of the Pioneer Fund, to outweigh the negative factors, such as the increase in net operating expenses for the Class B shares. The aggregate Rule 12b-1 distribution and shareholder servicing fees and non-Rule 12b-1 shareholder servicing fees paid by the Class A and Class B shares of both Funds are the same. Moreover, your AmSouth Fund's Class I shares pay a non 12b-1 shareholder servicing fee that is not paid by the Pioneer Fund's Class Y shares. In addition, the broader distribution arrangements of the Pioneer Fund offer greater potential for further asset growth and reduced per share expenses. Fifth, the substantially larger size of the combined Pioneer Oak Ridge Large Cap Growth Fund will offer greater opportunity for diversification of the investment portfolio, which should help to reduce risks. Sixth, the Class A, B and Y shares of Pioneer Oak Ridge Large Cap Growth Fund received in the Reorganization will provide AmSouth Capital Growth Fund shareholders with exposure to substantially the same investment product as they currently have. Seventh, The transaction is structured to qualify as a tax-free reorganization under Section 368(a) of the Internal Revenue Code of 1986 and therefore will not be treated as a taxable sale of your AmSouth shares. Although the Reorganization will result in a per share increase in net unrealized capital gains and decrease in capital loss carryforwards, the potential negative tax consequences of these aspects of the Reorganization are outweighed by the advantages of the Reorganization. Pioneer and AmSouth Bank will pay all costs of preparing and printing the AmSouth Funds' proxy statements and solicitation costs incurred by the AmSouth Funds in connection with the Reorganization. AAMI will otherwise be responsible for all costs and expenses of the AmSouth Funds in connection with the Reorganizations. The Trustees also considered that Pioneer and AmSouth Bank will benefit from the Reorganization. See "Will Pioneer and AmSouth Bank Benefit from the Reorganizations." The Board of Trustees of the Pioneer Fund also considered that the Reorganization presents an excellent opportunity for the Pioneer Fund to acquire investment assets 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 the Pioneer Fund and its shareholders. CAPITALIZATION The following table sets forth the capitalization of each Fund as of May 31, 2005, and the pro forma combined Fund as of May 31, 2005. The table also sets forth the pro forma capitalization of the combined Fund as of May 31, 2005, assuming the shareholders of AmSouth Large Cap Fund approve the reorganization of their fund into Pioneer Oak Ridge Large Cap Growth Fund. 16 - ------------------------------------------------------------------------------------------------------------------------------ Pro Forma Pioneer Oak Ridge Large Cap Growth Fund Pioneer Oak Ridge Pro Forma Pioneer Oak (including AmSouth Capital Large Cap Growth Ridge Large Cap AmSouth Large Cap Growth Fund Fund Growth Fund Fund) May 31, 2005 May 31, 2005 May 31, 2005 May 31, 2005 - ------------------------------------------------------------------------------------------------------------------------------ Total Net Assets (in thousands) $248,563 $220,176 $468,739 $799,086 - ------------------------------------------------------------------------------------------------------------------------------ Class A shares ................. $27,454 $87,287 $114,740 $228,425 - ------------------------------------------------------------------------------------------------------------------------------ Class B shares ................. $6,781 $10,999 $17,780 $40,130 - ------------------------------------------------------------------------------------------------------------------------------ Class I/Y shares ............... $214,328 $79,164 $293,493 $487,805 - ------------------------------------------------------------------------------------------------------------------------------ Net Asset Value Per Share - ------------------------------------------------------------------------------------------------------------------------------ Class A shares ................. $9.99 $12.66 $12.66 $12.66 - ------------------------------------------------------------------------------------------------------------------------------ Class B shares ................. $9.30 $12.54 $12.54 $12.54 - ------------------------------------------------------------------------------------------------------------------------------ Class I/Y shares ............... $10.01 $12.70 $12.70 $12.70 - ------------------------------------------------------------------------------------------------------------------------------ Shares Outstanding - ------------------------------------------------------------------------------------------------------------------------------ Class A shares ................. $2,747,560 $6,895,166 $9,063,867 $18,044,318 - ------------------------------------------------------------------------------------------------------------------------------ Class B shares ................. $729,523 $877,131 $1,417,918 $3,200,220 - ------------------------------------------------------------------------------------------------------------------------------ Class I/Y shares ............... $21,403,248 $6,234,510 $23,113,721 $38,416,647 - ------------------------------------------------------------------------------------------------------------------------------ It is impossible to predict how many shares of the Pioneer Fund will actually be received and distributed by your AmSouth Fund on the Reorganization date. The table should not be relied upon to determine the amount of the Pioneer Fund's shares that will actually be received and distributed. BOARD'S EVALUATION AND RECOMMENDATION For the reasons described above, the Trustees, including the Independent Trustees, approved the Reorganization. In particular, the Trustees determined that the Reorganization is in the best interests of your AmSouth Fund. Similarly, the Board of Trustees of the Pioneer Fund, including its Independent Trustees, approved the Reorganization. They also determined that the Reorganization is in the best interests of the Pioneer Fund. The Trustees recommend that the shareholders of your AmSouth Fund vote FOR the proposal to approve the Agreement and Plan of Reorganization. 17 AmSouth Large Cap Fund and Pioneer Oak Ridge Large Cap Growth Fund PROPOSAL 1(b) Approval of Agreement and Plan of Reorganization SUMMARY The following is a summary of more complete information appearing later in this Proxy Statement/Prospectus or incorporated herein.

You could lose money on your investment in either Fund or not make as much as if you invested elsewhere if: o The stock market goes down (this risk may be greater in the short term) o Large company or growth stocks fall out of favor with investors o The adviser's/subadviser's judgment about the attractiveness, growth potential or potential appreciation of a particular stock proves to be incorrect 8 Pioneer Oak Ridge Large Cap Growth Fund may be subject to the following additional risks associated with investing in non-U.S. issuers, which may involve unique risks compared to investing in securities of U.S. issuers. These risks are more pronounced to the extent the Fund invests in issuers in countries with emerging markets or if the Fund invests significantly in one 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, the adviser/subadviser might 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 In addition, at times, more than 25% of Pioneer Oak Ridge Large Cap Growth Fund's assets may be invested in the same market segment, such as financials or technology. To the extent the Fund emphasizes 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. Although the Pioneer Oak Ridge Large Cap Growth Fund is classified as a diversified investment company, the Fund's portfolio may be comprised of fewer issuers than many large cap growth funds. Typically, the subadviser expects the portfolio to include a limited number of different issuers, which may increase the volatility of the Fund's net asset value per share. Past Performance Set forth below is performance information for each Fund. The bar charts show how each Fund's total return (not including any deduction for sales charges) has varied from year to year for each full calendar year. The tables show average annual total return (before and after 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 bar charts give an indication of the risks of investing in each Fund, including the fact that you could incur a loss and experience volatility of returns year to year. Past performance before and after taxes does not indicate future results.

Pursuant to an agreement and plan of reorganization, the Pioneer Fund acquired all of the assets and those liabilities reflected in the net assets of Oak Ridge Large Cap Equity Fund (the predecessor fund) on February 13, 2004. In the reorganization, the predecessor fund exchanged all of its assets for Class A shares of the Fund. The predecessor fund offered only one class of shares which was most similar to Class A shares of the Pioneer Fund. As a result of that reorganization, the Pioneer Fund is the accounting successor of the predecessor fund, which commenced operations on March 1, 1999. The Pioneer Fund's subadviser served as the predecessor fund's investment adviser. The performance of each class of the Pioneer Fund includes the performance of the predecessor fund's shares prior to the 2004 reorganization, which has been restated to reflect differences in any applicable sales charges and Rule 12b-1 fees (but not other differences in expenses). This adjustment had the effect of reducing the previously reported performance of the predecessor fund.

The table above shows the impact of taxes on AmSouth Large Cap Fund's returns. After-tax returns are only shown for Class A shares and Class I shares and may vary for Class B shares. The Fund's after-tax returns are calculated using the highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. In certain cases, the figure representing "Return After Taxes on Distributions and Sale of Fund Shares" may be higher than the other return figures for the same period. A higher after-tax return results when a capital loss occurs upon redemption and translates into an assumed tax deduction that benefits the shareholder. Please note that actual after-tax returns depend on an investor's tax situation and may differ from those shown. Also note that after-tax returns shown are not relevant to investors who hold their Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

Any fee waiver or expense reimbursement arrangement is voluntary and may be discontinued at any time. (6) The Pioneer Fund's total annual operating expenses in the table have not been reduced by any expense offset arrangements. (7) The expenses in the table above reflect the expense limitations currently in effect for the Pioneer Fund, under which Pioneer has contractually agreed to limit ordinary operating expenses to the extent required to reduce fund expenses to 1.30%, and 2.20% of the average daily net assets attributable to Class A and Class B shares, respectively. These expense limitations are in effect through April 1, 2008 for Class A shares and through April 1, 2006 for Class B shares. There can be no assurance that Pioneer will extend the expense limitations beyond such time.

This expense limitation is in effect through April 1, 2007. There can be no assurance that Pioneer will extend the expense limitations beyond such time. 14 The hypothetical example below helps you compare the cost of investing in each Fund. It assumes that: (a) you invest $10,000 in each Fund for the time periods shown, (b) you reinvest all dividends and distributions, (c) your investment has a 5% return each year, and (d) each Fund's gross operating expenses remain the same,. The examples are for comparison purposes only and are not a representation of either Fund's actual expenses or returns, either past or future. - ------------------------------------------------------------------------------------------------------------ Combined Fund (including AmSouth Number of years you AmSouth Large Cap Pioneer Oak Ridge Large Combined Fund Capital Growth Fund) own your shares Fund Cap Growth Fund (Pro Forma) (Pro Forma) - ------------------------------------------------------------------------------------------------------------ Class A - ------------------------------------------------------------------------------------------------------------ Year 1 $683 $700 $691 $689 - ------------------------------------------------------------------------------------------------------------ Year 3 $963 $963 $937 $931 - ------------------------------------------------------------------------------------------------------------ Year 5 $1,264 $1,485 $1,202 $1,192 - ------------------------------------------------------------------------------------------------------------ Year 10 $2,116 $2,913 $1,957 $1,935 - ------------------------------------------------------------------------------------------------------------ Class B -- assuming redemption at end of period - ------------------------------------------------------------------------------------------------------------ Year 1 $719 $623 $613 $613 - ------------------------------------------------------------------------------------------------------------ Year 3 $976 $1,140 $975 $979 - ------------------------------------------------------------------------------------------------------------ Year 5 $1,359 $1,583 $1,280 $1,271 - ------------------------------------------------------------------------------------------------------------ Year 10 $2,295 $3,086 $2,304 $2,270 - ------------------------------------------------------------------------------------------------------------ Class B -- assuming no redemption - ------------------------------------------------------------------------------------------------------------ Year 1 $219 $223 $213 $213 - ------------------------------------------------------------------------------------------------------------ Year 3 $676 $840 $675 $679 - ------------------------------------------------------------------------------------------------------------ Year 5 $1,159 $1,483 $1,180 $1,171 - ------------------------------------------------------------------------------------------------------------ Year 10 $2,295 $3,086 $2,304 $2,270 - ------------------------------------------------------------------------------------------------------------ Class I Class Y - ------------------------------------------------------------------------------------------------------------ Year 1 $130 $121 $90 $88 - ------------------------------------------------------------------------------------------------------------ Year 3 $406 $378 $281 $274 - ------------------------------------------------------------------------------------------------------------ Year 5 $702 $654 $488 $477 - ------------------------------------------------------------------------------------------------------------ Year 10 $1,545 $1,443 $1,084 $1,061 - ------------------------------------------------------------------------------------------------------------ Reasons for the Proposed Reorganization The Trustees believe that the proposed Reorganization is in the best interests of AmSouth Large Cap Fund and its shareholders. The Trustees considered the following matters, among others, in approving the proposal. First, AAMI, the investment adviser to your AmSouth Fund, informed the Trustees that it does not intend to continue to provide investment advisory services to the AmSouth Funds. Consequently, a change in your AmSouth Fund's investment adviser was necessary. In the absence of the Reorganization, such a change would be more likely to motivate shareholders invested in reliance on AAMI's role to withdraw from the Fund, thereby reducing fund size and increasing fund expense ratios. Second, the historical investment performance of Pioneer Oak Ridge Large Cap Growth Fund is significantly better than your AmSouth Fund's investment performance. For the one and five year periods ended December 31, 2004, Class A shares of Pioneer Oak Ridge Large Cap Growth Fund had an average annual return of 4.96% (one year) and -0.54% (five year); compared to an average annual return of the Class A shares of your AmSouth Fund of -0.53% (one year); and -3.62% (five year); respectively, during the same period. In addition, the Trustees considered the track record of Pioneer in managing equity and fixed income mutual funds. Third, the resources of Pioneer. At December 31, 2004, Pioneer managed over 80 investment companies and accounts with approximately $42 billion in assets, including $26.7 billion in equity securities. Pioneer is part of the global asset management group of UniCredito Italiano S.p.A., one of the largest banking groups in Italy, providing investment management 15 and financial services to mutual funds, institutional and other clients. As of December 31, 2004, assets under management of UniCredito Italiano S.p.A. were approximately $175 billion worldwide. Shareholders of your AmSouth Fund would become part of a significantly larger family of funds that offers a more diverse array of investment options and enhanced shareholder account options. The Pioneer family of mutual funds offers over 80 funds, including domestic and international equity and fixed income funds and a money market fund that will be available to your AmSouth Fund's shareholders through exchanges. Fourth, Pioneer Oak Ridge Large Cap Growth Fund's management fee (0.75% of average daily net assets) is lower than the advisory fee of your Fund (0.80% of average daily net assets). Although the historical gross and net expenses of Pioneer Oak Ridge Large Cap Growth Fund are higher than your Fund's historical gross and net expenses (except for Class Y shares), the estimated pro forma expenses of Class A and Class Y Shares of the Pioneer Fund after giving effect to the Reorganizations on both a gross and net basis are lower than your Fund's gross and net operating expenses for the Class A and I shares. Although the pro forma operating expenses for the Class B shares are estimated to increase slightly, this increase is partly the result of expense limitations on your AmSouth Fund that are voluntary and may be discontinued at any time. AmSouth Bank and its affiliates have informed the trustees that they will discontinue their expense limitations in the future. The trustees considered the positive factors associated with the Reorganization, such as the superior performance of the Pioneer Fund, to outweigh the negative factors, such as the increase in expenses. The aggregate Rule 12b-1 distribution and shareholder servicing fees and non-Rule 12b-1 shareholder servicing fees paid by the Class A and Class B shares of both Funds are the same. Moreover, your AmSouth Fund's Class I shares pay a non 12b-1 shareholder servicing fee that is not paid by the Pioneer Fund's Class Y shares. In addition, the broader distribution arrangements of the Pioneer Fund offer greater potential for further asset growth and reduced per share expenses. Fifth, the substantially larger size of the combined Pioneer Oak Ridge Large Cap Growth Fund will offer greater opportunity for diversification of the investment portfolio, which should help to reduce risks. Sixth, the Class A, B and Y shares of Pioneer Oak Ridge Large Cap Growth Fund received in the Reorganization will provide AmSouth Large Cap Fund shareholders with exposure to substantially the same investment product as they currently have. Seventh, the transaction is structured to qualify as a tax-free reorganization under Section 368(a) of the Internal Revenue Code of 1986 and therefore will not be treated as a taxable sale of your AmSouth shares. Pioneer and AAMI will pay all costs of preparing and printing the Funds' proxy statements and solicitation costs incurred by the Funds in connection with the Reorganization. AAMI will otherwise be responsible for all costs and expenses of the AmSouth Fund in connection with the Reorganizations. The Trustees also considered that Pioneer and AmSouth Bank will benefit from the Reorganization. See "Will Pioneer and AmSouth Bank Benefit from the Reorganizations." The Board of Trustees of the Pioneer Fund also considered that the Reorganization presents an excellent opportunity for the Pioneer Fund to acquire investment assets 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 the Pioneer Fund and its shareholders. CAPITALIZATION The following table sets forth the capitalization of each Fund as of May 31, 2005, and the pro forma combined Fund as of May 31, 2005. The table also sets forth the pro forma capitalization of the combined Fund as of May 31, 2005, assuming the shareholders of AmSouth Capital Growth Fund approve the reorganization of their fund into Pioneer Oak Ridge Large Cap Growth Fund. 16 - -------------------------------------------------------------------------------------------------------------------------------- Pro Forma Pioneer Oak Pro Forma Ridge Large Cap Pioneer Oak Pioneer Oak Growth Fund Ridge Large Cap Ridge Large (including AmSouth Large Growth Cap Growth AmSouth Capital Cap Fund Fund Fund Growth Fund) May 31, 2005 May 31, 2005 May 31, 2005 May 31, 2005 - -------------------------------------------------------------------------------------------------------------------------------- Total Net Assets (in thousands) $330,347 $220,176 $550,522 $799,086 - -------------------------------------------------------------------------------------------------------------------------------- Class A shares ................................... $113,684 $87,287 $200,971 $228,425 - -------------------------------------------------------------------------------------------------------------------------------- Class B shares ................................... $22,350 $10,999 $33,348 $40,130 - -------------------------------------------------------------------------------------------------------------------------------- Class I/Y shares ................................. $194,313 $79,164 $273,477 $487,805 - -------------------------------------------------------------------------------------------------------------------------------- Net Asset Value Per Share - -------------------------------------------------------------------------------------------------------------------------------- Class A shares ................................... $18.35 $12.66 $12.66 $12.66 - -------------------------------------------------------------------------------------------------------------------------------- Class B shares ................................... $17.35 $12.54 $12.54 $12.54 - -------------------------------------------------------------------------------------------------------------------------------- Class I/Y shares ................................. $18.46 $12.70 $12.70 $12.70 - -------------------------------------------------------------------------------------------------------------------------------- Shares Outstanding - -------------------------------------------------------------------------------------------------------------------------------- Class A shares ................................... $6,194,719 $6,895,166 $15,875,617 $18,044,318 - -------------------------------------------------------------------------------------------------------------------------------- Class B shares ................................... $1,288,165 $877,131 $2,659,432 $3,200,220 - -------------------------------------------------------------------------------------------------------------------------------- Class I/Y shares ................................. $10,525,146 $6,234,510 $21,537,436 $38,416,647 - -------------------------------------------------------------------------------------------------------------------------------- It is impossible to predict how many shares of the Pioneer Fund will actually be received and distributed by your AmSouth Fund on the Reorganization date. The table should not be relied upon to determine the amount of the Pioneer Fund's shares that will actually be received and distributed. BOARD'S EVALUATION AND RECOMMENDATION For the reasons described above, the Trustees, including the Independent Trustees, approved the Reorganization. In particular, the Trustees determined that the Reorganization is in the best interests of your AmSouth Fund. Similarly, the Board of Trustees of the Pioneer Fund, including its Independent Trustees, approved the Reorganization. They also determined that the Reorganization is in the best interests of the Pioneer Fund. The Trustees recommend that the shareholders of your AmSouth Fund vote FOR the proposal to approve the Agreement and Plan of Reorganization. 17 AmSouth Enhanced Market Fund and Pioneer Fund PROPOSAL 1(c) Approval of Agreement and Plan of Reorganization 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-1, because it contains details that are not in the summary. Each Fund invests primarily in the equity securities of large cap U.S. issuers and, consequently, has similar investment policies and risks. Your Fund, while not a pure index fund, seeks to track closely the S&P 500 Stock Index, while the Pioneer Fund is actively managed and does not have a goal of tracking an index. In the table below, if a row extends across the entire table, the policy disclosed applies to both your AmSouth Fund and the Pioneer Fund.

The subadviser's stock selection process utilizes computer-aided quantitative analysis. The subadviser's computer models use many types of data, but emphasize technical data such as price and volume information. Applying these models to stocks within the S&P 500, the subadviser hopes to generate more capital growth than that of the S&P 500. The subadviser's emphasis on technical analyses can result in significant shifts in portfolio holdings at different times. However, stringent risk controls at the style, industry and individual stock levels help ensure the Fund maintains risk characteristics similar to those of the S&P 500. - ------------------------------------------------------------------------------------------------------------------------------------ Other investments AmSouth Enhanced Market Fund may invest Pioneer Fund may invest up to 10% of its total - ------------------------------------------------------------------------------------------------------------------------------------ 2 - ------------------------------------------------------------------------------------------------------------------------------------ AmSouth Enhanced Market Fund Pioneer Fund - ------------------------------------------------------------------------------------------------------------------------------------ up to 20% of its total assets in equity assets in equity and debt securities of securities not held in the S&P 500, corporate non-U.S. corporate issuers and debt bonds, notes, and warrants, and short-term securities of non-U.S. government issuers. money market instruments.

The Fund uses a "first-in, first-out" method to determine how long you have held your shares. This means that if you purchased shares on different days, the shares purchased first will be considered redeemed first for purposes of determining whether the redemption fee will be charged. The fee will be charged on all covered redemptions and exchanges, including those made through retirement plan, brokerage and other types of omnibus accounts (except where it is not practical for the plan administrator or brokerage firm to implement the fee). The Fund will not impose the redemption fee on a redemption or exchange of shares purchased upon the reinvestment of dividend and capital gain distributions. - ------------------------------------------------------------------------------------------------------------------------------------ Selling shares Shares of each Fund are sold at the net asset value per share next calculated after the Fund receives your request in good order. -------------------------------------------------------------------------------------------------- You may sell your shares by contacting the Normally, your investment firm will send your Fund directly in writing or by telephone or request to sell shares to PIMSS.

You could lose money on your investment in either Fund or not make as much as if you invested elsewhere if: o The stock market goes down (this risk may be greater in the short term) o In the case of the Pioneer Fund, value stocks fall out of favor with investors o The Fund's assets remain undervalued or do not have the potential value originally expected o Stocks selected for income do not achieve the same return as securities selected for capital growth 8 Past Performance Set forth below is performance information for each Fund. The bar charts show how each Fund's total return (not including any deduction for sales charges) has varied from year to year for each full calendar year. The tables show average annual total return (before and after 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 bar charts give an indication of the risks of investing in each Fund, including the fact that you could incur a loss and experience volatility of returns year to year. Past performance before and after taxes does not indicate future results.

The Fund's after-tax returns are calculated using the highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. In certain cases, the figure representing "Return After Taxes on Distributions and Sale of Fund Shares" may be higher than the other return figures for the same period. A higher after-tax return results when a capital loss occurs upon redemption and translates into an assumed tax deduction that benefits the shareholder. Please note that actual after-tax returns depend on an investor's tax situation and may differ from those shown. Also note that 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.

(2) Sales charges may be reduced depending upon the amount invested or, in certain circumstances, waived. Class A shares bought as part of an investment of $1 million or more are not subject to an initial sales charge, but may be charged a CDSC of 1.00% if sold within one year of purchase. (3) For Class B shares purchased prior to the combination of AmSouth Funds with ISG Funds, the CDSC on such Class B shares held continuously declines over six years, starting with year one and ending in year seven from: 4%, 3%, 3%, 2%, 2%, 1%. For all other Class B shares held continuously, the CDSC declines over six years, starting with year one and ending in year seven from: 5%, 4%, 3%, 3%, 2%, 1%. Eight years after purchase (seven years in the case of shares acquired in the ISG combination), Class B shares automatically convert to Class A shares. (4) To discourage short-term trading, a redemption fee of 2.00% will be charged on sales or exchanges of Class A, Class B and Class I shares of your AmSouth Fund made within 7 days of the date of purchase. A wire transfer fee of $7.00 will be deducted from the amount of your redemption if you request a wire transfer. (5) Other expenses for your AmSouth Fund are being limited to 0.56% for Class A shares, 0.56% for Class B shares and 0.41% for Class I shares. Any fee waiver or expense reimbursement arrangement is voluntary and may be discontinued at any time. (6) Pioneer Fund pays a management fee that ranges from 0.50% to 0.70% of average daily net assets based on its performance. (7) The Pioneer Fund's total annual operating expenses in the table have not been reduced by any expense offset arrangements. The hypothetical example below helps you compare the cost of investing in each Fund. It assumes that: (a) you invest $10,000 in each Fund for the time periods shown, (b) you reinvest all dividends and distributions, (c) your investment has a 5% return each year, and (d) each Fund's gross operating expenses remain the same. The examples are for comparison purposes only and are not a representation of either Fund's actual expenses or returns, either past or future. - ------------------------------------------------------------------------------------------------------------ Number of years you AmSouth Enhanced Marked Fund Pioneer Fund Combined Fund own your shares (Pro Forma) - ------------------------------------------------------------------------------------------------------------ Class A - ------------------------------------------------------------------------------------------------------------ Year 1 $646 $667 $676 - ------------------------------------------------------------------------------------------------------------ Year 3 $851 $893 $890 - ------------------------------------------------------------------------------------------------------------ Year 5 $1,072 $1,126 $1,121 - ------------------------------------------------------------------------------------------------------------ 12 - ------------------------------------------------------------------------------------------------------------ Year 10 $1,707 $1,795 $1,784 - ------------------------------------------------------------------------------------------------------------ Class B -- assuming redemption at end of period - ------------------------------------------------------------------------------------------------------------ Year 1 $684 $596 $595 - ------------------------------------------------------------------------------------------------------------ Year 3 $869 $906 $903 - ------------------------------------------------------------------------------------------------------------ Year 5 $1,180 $1,142 $1,137 - ------------------------------------------------------------------------------------------------------------ Year 10 $1,914 $2,028 $2,017 - ------------------------------------------------------------------------------------------------------------ Class B -- assuming no redemption - ------------------------------------------------------------------------------------------------------------ Year 1 $184 $196 $195 - ------------------------------------------------------------------------------------------------------------ Year 3 $569 $606 $603 - ------------------------------------------------------------------------------------------------------------ Year 5 $980 $1,042 $1,037 - ------------------------------------------------------------------------------------------------------------ Year 10 $1,914 $2,028 $2,017 - ------------------------------------------------------------------------------------------------------------ Class I Class Y - ------------------------------------------------------------------------------------------------------------ Year 1 $90 $62 $61 - ------------------------------------------------------------------------------------------------------------ Year 3 $281 $195 $192 - ------------------------------------------------------------------------------------------------------------ Year 5 $488 $340 $335 - ------------------------------------------------------------------------------------------------------------ Year 10 $1084 $762 $750 - ------------------------------------------------------------------------------------------------------------ Reasons for the Proposed Reorganization The Trustees believe that the proposed Reorganization is in the best interests of AmSouth Enhanced Market Fund. The Trustees considered the following matters, among others, in approving the proposal. First, AAMI, the investment adviser to your AmSouth Fund, informed the Trustees that it does not intend to continue to provide investment advisory services to the AmSouth Funds. Consequently, a change in your AmSouth Fund's investment adviser was necessary. In the absence of the Reorganization, such a change would be more likely to motivate shareholders invested in reliance on AAMI's role to withdraw from the Fund, thereby reducing fund size and increasing fund expense ratios. Second, after the Reorganization, the combined Fund will have an asset size substantially larger than that of your AmSouth Fund, which may allow the combined Fund to achieve significant economies of scale in investments or expenses. Third, the historical investment performance of Pioneer Fund is superior to your AmSouth Fund's investment performance. For the one and five year periods ended December 31, 2004, Class A shares of Pioneer Fund had an average annual return of 5.21% (one year); and -1.44% (five year); compared to an average annual return of the Class A shares of your AmSouth Fund of 3.98% (one year); and -3.99% (five year), respectively, during the same period. In addition, the Trustees considered the track record of Pioneer in managing equity and fixed income mutual funds. Fourth, the resources of Pioneer. At December 31, 2004, Pioneer managed over 80 investment companies and accounts with approximately $42 billion in assets, including $26.7 billion in equity securities. Pioneer is part of the global asset management group of UniCredito Italiano S.p.A., one of the largest banking groups in Italy, providing investment management and financial services to mutual funds, institutional and other clients. As of December 31, 2004, assets under management of UniCredito Italiano S.p.A. were approximately $175 billion worldwide. Shareholders of your AmSouth Fund would become part of a significantly larger family of funds that offers a more diverse array of investment options and enhanced shareholder account options. The Pioneer family of mutual funds offers over 80 funds, including domestic and international equity and fixed income funds and a money market fund that will be available to your AmSouth Fund's shareholders through exchanges. Fifth, the Trustees recognized that Pioneer Fund's operating expenses for Class A and Class B shares, both gross and net of expense limitations, and its management fee, are higher than your Fund's expenses for Class A and Class B shares and your Fund's management fee. They also noted that on a pro forma basis, after giving effect to the Reorganization, the expenses of the Pioneer Fund's Class A and Class B shares were estimated to be higher that your Fund's expenses for Class A and Class B shares both on a gross and a net basis, though the gross and net expenses of your Fund's Class I shares would decline. The Trustees noted that the differential in fees can be explained by the fact that the Pioneer Fund is more actively managed, while the AmSouth Fund is an enhanced index fund, and index funds traditionally have substantially lower fees than actively 13 managed funds. The Trustees considered that the other advantages of the Reorganization were sufficient to make up for the higher expenses of the Pioneer Fund. The Trustees also considered that the aggregate Rule 12b-1 distribution and shareholder servicing fees and non-Rule 12b-1 shareholder servicing fees paid by the Class A and Class B shares of both Funds are the same. Moreover, your AmSouth Fund's Class I shares pay a non 12b-1 shareholder servicing fee that is not paid by the Pioneer Fund's Class Y shares. In addition, the broader distribution arrangements of the Pioneer Fund offer greater potential for further asset growth and reduced per share expenses. Sixth, the substantially larger size of Pioneer Fund will offer greater opportunity for diversification of the investment portfolio, which should help to reduce risks. Seventh, the Class A, B and Y shares of Pioneer Fund received in the Reorganization will provide AmSouth Enhanced Market Fund shareholders with exposure to substantially the same investment product as they currently have. Eighth, the transaction is structured to qualify as a tax-free reorganization under Section 368(a) of the Internal Revenue Code of 1986 and therefore will not be treated as a taxable sale of your AmSouth shares. Although the Reorganization will result in a per share increase in net unrealized capital gains and decrease in capital loss carryforwards, the potential negative tax consequences of these aspects of the Reorganization are outweighed by the advantages of the Reorganization. Pioneer and AmSouth Bank will pay all costs of preparing and printing the Funds' proxy statements and solicitation costs incurred by the Funds in connection with the Reorganization. AAMI will otherwise be responsible for all costs and expenses of the AmSouth Fund in connection with the Reorganizations. The Trustees also considered that Pioneer and AmSouth Bank will benefit from the Reorganization. See "Will Pioneer and AmSouth Bank Benefit from the Reorganizations." The Board of Trustees of the Pioneer Fund also considered that the Reorganization presents an excellent opportunity for the Pioneer Fund to acquire investment assets 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 the Pioneer Fund and its shareholders.

The table should not be relied upon to determine the amount of the Pioneer Fund's shares that will actually be received and distributed. 14 BOARD'S EVALUATION AND RECOMMENDATION For the reasons described above, the Trustees, including the Independent Trustees, approved the Reorganization. In particular, the Trustees determined that the Reorganization is in the best interests of your AmSouth Fund. Similarly, the Board of Trustees of the Pioneer Fund, including its Independent Trustees, approved the Reorganization. They also determined that the Reorganization is in the best interests of the Pioneer Fund. The Trustees recommend that the shareholders of your AmSouth Fund vote FOR the proposal to approve the Agreement and Plan of Reorganization. 15 AmSouth Value Fund and Pioneer Value Fund PROPOSAL 1(d) Approval of Agreement and Plan of Reorganization SUMMARY The following is a summary of more complete information appearing later in this Proxy Statement/Prospectus or incorporated herein.

You could lose money on your investment in either Fund or not make as much as if you invested elsewhere if: o The stock market goes down (this risk may be greater in the short term) 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 Pioneer Value Fund may be subject to the following additional risks associated with investing in non-U.S. issuers, which may involve unique risks compared to investing in securities of U.S. issuers. These risks are more pronounced to the extent the Fund invests in issuers in countries with emerging markets or if the Fund invests significantly in one 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, the adviser/subadviser might not be able to sell the Fund's portfolio securities at times, in amounts and at prices it considers reasonable 8 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 In addition, at times, more than 25% of Pioneer Value Fund's assets may be invested in the same market segment, such as financials or technology. To the extent the Fund emphasizes 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. Past Performance Set forth below is performance information for each Fund. The bar charts show how each Fund's total return (not including any deduction for sales charges) has varied from year to year for each full calendar year. The tables show average annual total return (before and after 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 bar charts give an indication of the risks of investing in each Fund, including the fact that you could incur a loss and experience volatility of returns year to year. Past performance before and after taxes does not indicate future results.

The historical performance of the Class B shares has been restated to reflect the Fund's Class B shares distribution (12b-1) fees and the contingent deferred sales charge.

The table above shows the impact of taxes on AmSouth Value Fund's returns. After-tax returns are only shown for Class A and Class I shares and may vary for Class B shares. The Fund's after-tax returns are calculated using the highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. In certain cases, the figure representing "Return After Taxes on Distributions and Sale of Fund Shares" may be higher than the other return figures for the same period. A higher after-tax return results when a capital loss occurs upon redemption and translates into an assumed tax deduction that benefits the shareholder. Please note that actual after-tax returns depend on an investor's tax situation and may differ from 10 those shown. Also note that after-tax returns shown are not relevant to investors who hold their Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

(5) Other expenses for your AmSouth Fund are being limited to 0.52% for Class A shares, 0.52% for Class B shares and 0.37% for Class I shares. Any fee waiver or expense reimbursement arrangement is voluntary and may be discontinued at any time. (6) Pioneer Value Fund pays a management fee that ranges from 0.50% to 0.70% of average daily net assets based on its performance. The Fund's basic fee before any performance adjustment is 0.60% of average daily net assets, which fee is reduced at asset levels above $5 billion. (7) Pioneer Value Fund's total annual operating expenses have not been reduced by any expense offset arrangements. The hypothetical example below helps you compare the cost of investing in each Fund. It assumes that: (a) you invest $10,000 in each Fund for the time periods shown, (b) you reinvest all dividends and distributions, (c) your investment has a 5% return each year, and (d) each Fund's gross operating expenses remain the same. The examples are for comparison purposes only and are not a representation of either Fund's actual expenses or returns, either past or future. - ------------------------------------------------------------------------------------------------------------ Number of years you AmSouth Value Fund Pioneer Value Fund Combined Fund own your shares (Pro Forma) - ------------------------------------------------------------------------------------------------------------ Class A - ------------------------------------------------------------------------------------------------------------ Year 1 $681 $671 $671 - ------------------------------------------------------------------------------------------------------------ Year 3 $957 $875 $875 - ------------------------------------------------------------------------------------------------------------ Year 5 $1,254 $1,096 $1,096 - ------------------------------------------------------------------------------------------------------------ Year 10 $2.095 $1,729 $1,729 - ------------------------------------------------------------------------------------------------------------ Class B -- assuming redemption at end of period - ------------------------------------------------------------------------------------------------------------ Year 1 $716 $591 $591 - ------------------------------------------------------------------------------------------------------------ Year 3 $967 $891 $891 - ------------------------------------------------------------------------------------------------------------ Year 5 $1,344 $1,116 $1,116 - ------------------------------------------------------------------------------------------------------------ Year 10 $2,266 $1,971 $1,971 - ------------------------------------------------------------------------------------------------------------ Class B -- assuming no redemption - ------------------------------------------------------------------------------------------------------------ Year 1 $216 $191 $191 - ------------------------------------------------------------------------------------------------------------ Year 3 $667 $591 $591 - ------------------------------------------------------------------------------------------------------------ Year 5 $1,144 $1,016 $1,016 - ------------------------------------------------------------------------------------------------------------ Year 10 $2,266 $1,971 $1,971 - ------------------------------------------------------------------------------------------------------------ Class I Class Y - ------------------------------------------------------------------------------------------------------------ Year 1 $128 $63 $63 - ------------------------------------------------------------------------------------------------------------ Year 3 $400 $199 $199 - ------------------------------------------------------------------------------------------------------------ Year 5 $692 $346 $346 - ------------------------------------------------------------------------------------------------------------ Year 10 $1,523 $774 $774 - ------------------------------------------------------------------------------------------------------------ Reasons for the Proposed Reorganization The Trustees believe that the proposed Reorganization is in the best interests of AmSouth Value Fund. The Trustees considered the following matters, among others, in approving the proposal. First, AAMI, the investment adviser to your AmSouth Fund, informed the Trustees that it does not intend to continue to provide investment advisory services to the AmSouth Funds. Consequently, a change in your AmSouth Fund's investment 13 adviser was necessary. In the absence of the Reorganization, such a change would be more likely to motivate shareholders invested in reliance on AAMI's role to withdraw from the Fund, thereby reducing fund size and increasing fund expense ratios. Second, after the Reorganization, the combined Fund will have an asset size substantially larger than that of your AmSouth Fund, which may allow the combined Fund to achieve significant economies of scale in investments or expenses. Third, the historical investment performance of Pioneer Value Fund is comparable to your AmSouth Fund's investment performance. For the one, five and ten year periods ended December 31, 2004, Class A shares of Pioneer Value Fund had an average annual return of 5.78% (one year); 4.42% (five year); and 8.34% (ten year), compared to an average annual return of the Class A shares of your AmSouth Fund of 8.78% (one year); 1.02% (five year); and 9.62% (ten year), respectively, during the same period. In addition, the Trustees considered the track record of Pioneer in managing equity and fixed income mutual funds. Fourth, the resources of Pioneer. At December 31, 2004, Pioneer managed over 80 investment companies and accounts with approximately $42 billion in assets. Pioneer is part of the global asset management group of UniCredito Italiano S.p.A., one of the largest banking groups in Italy, providing investment management and financial services to mutual funds, institutional and other clients. As of December 31, 2004, assets under management of UniCredito Italiano S.p.A. were approximately $175 billion worldwide. Shareholders of your AmSouth Fund would become part of a significantly larger family of funds that offers a more diverse array of investment options and enhanced shareholder account options. The Pioneer family of mutual funds offers over 80 funds, including domestic and international equity and fixed income funds and a money market fund that will be available to your AmSouth Fund's shareholders through exchanges. Fifth, Pioneer Value Fund's management fee (0.60% of average daily net assets as of as of March 31, 2005) is substantially lower than the advisory fees of your Fund (0.80% of average daily net assets). The aggregate Rule 12b-1 distribution and shareholder servicing fees and non-Rule 12b-1 shareholder servicing fees paid by the Class A and Class B shares of both Funds are the same. Moreover, your AmSouth Fund's Class I shares pay a non 12b-1 shareholder servicing fee that is not paid by the Pioneer Fund's Class Y shares. Pioneer Value Fund's expenses are lower than your Fund's expenses on both a gross and net basis. On a pro forma basis, after giving effect to the Reorganization, it is estimated that the Pioneer Value Fund's expenses will also be lower than you Fund's expenses on a gross and net basis. In addition, the broader distribution arrangements of the Pioneer Fund offer greater potential for further asset growth and reduced per share expenses. Sixth, the substantially larger size of the combined Pioneer Value Fund will offer greater opportunity for diversification of the investment portfolio, which should help to reduce risks. Seventh, the Class A, B and Y shares of Pioneer Value Fund received in the Reorganization will provide AmSouth Value Fund shareholders with exposure to substantially the same investment product as they currently have. Eighth, the transaction is structured to qualify as a tax-free reorganization under Section 368(a) of the Internal Revenue Code of 1986 and therefore will not be treated as a taxable sale of your AmSouth shares. Although the Reorganization will result in a per share decrease in capital loss carryforwards, the potential negative tax consequences of this aspect of the Reorganization are outweighed by the advantages of the Reorganization. Pioneer and AmSouth Bank will pay all costs of preparing and printing the Funds' proxy statements and solicitation costs incurred by the Funds in connection with the Reorganization. AAMI will otherwise be responsible for all costs and expenses of the AmSouth Fund in connection with the Reorganizations. The Trustees also considered that Pioneer and AmSouth Bank will benefit from the Reorganization. See "Will Pioneer and AmSouth Bank Benefit from the Reorganizations." The Board of Trustees of the Pioneer Fund also considered that the Reorganization presents an excellent opportunity for the Pioneer Fund to acquire investment assets 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 the Pioneer Fund and its shareholders. 14 CAPITALIZATION The following table sets forth the capitalization of each Fund as of May 31, 2005, and the pro forma combined Fund as of May 31, 2005. - ----------------------------------------------------------------------------------------------------------------------- Pioneer Value Pro Forma Pioneer AmSouth Value Fund Fund Value Fund May 31, 2005 May 31, 2005 May 31, 2005 - ----------------------------------------------------------------------------------------------------------------------- Total Net Assets (in thousands) $481,874 $3,992,881 $4,474,755 - ----------------------------------------------------------------------------------------------------------------------- Class A shares ................................... $132,299 $3,817,843 $3,950,143 - ----------------------------------------------------------------------------------------------------------------------- Class B shares ................................... $27,013 $27,494 $54,507 - ----------------------------------------------------------------------------------------------------------------------- Class I /Y shares ................................ $322,562 $12,907 $335,469 - ----------------------------------------------------------------------------------------------------------------------- Net Asset Value Per Share - ----------------------------------------------------------------------------------------------------------------------- Class A shares ................................... $16.75 $17.63 $17.63 - ----------------------------------------------------------------------------------------------------------------------- Class B shares ................................... $16.40 $16.55 $16.55 - ----------------------------------------------------------------------------------------------------------------------- Class I/Y shares ................................. $16.72 $17.68 $17.68 - ----------------------------------------------------------------------------------------------------------------------- Shares Outstanding - ----------------------------------------------------------------------------------------------------------------------- Class A shares ................................... 7,896,883 216,506,470 244,009,051 - ----------------------------------------------------------------------------------------------------------------------- Class B shares ................................... 1,647,053 1,661,225 3,293,388 - ----------------------------------------------------------------------------------------------------------------------- Class I/Y shares ................................. 19,287,248 730,157 18,977,538 - ----------------------------------------------------------------------------------------------------------------------- It is impossible to predict how many shares of the Pioneer Fund will actually be received and distributed by your AmSouth Fund on the Reorganization date. The table should not be relied upon to determine the amount of the Pioneer Fund's shares that will actually be received and distributed. BOARD'S EVALUATION AND RECOMMENDATION For the reasons described above, the Trustees, including the Independent Trustees, approved the Reorganization. In particular, the Trustees determined that the Reorganization is in the best interests of your AmSouth Fund. Similarly, the Board of Trustees of the Pioneer Fund, including its Independent Trustees, approved the Reorganization. They also determined that the Reorganization is in the best interests of the Pioneer Fund. The Trustees recommend that the shareholders of your AmSouth Fund vote FOR the proposal to approve the Agreement and Plan of Reorganization. 15 AmSouth Mid Cap Fund and Pioneer Mid Cap Value Fund PROPOSAL 1(e) Approval of Agreement and Plan of Reorganization 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-1, because it contains details that are not in the summary.

Pioneer currently is effect to the expense limitation, were 1.33% waiving the floor on its fee. Pioneer may of average daily net assets. reimpose the same floor in the future, but will not be entitled to recover any previously waived fees. Because the adjustment to the basic fee is based on the comparative performance of the Fund and the performance record of the index, the controlling factor is not whether Fund performance is up or down, but whether it is up or down more or less than the performance record of the index, regardless of general market performance. As a result, Pioneer could earn the maximum possible fee even if the Fund's net asset declines. Moreover, the comparative investment performance of the Fund is based solely on the relevant performance period without regard to the cumulative performance over a longer or shorter period of time.

You could lose money on your investment in either Fund or not make as much as if you invested elsewhere if: o The stock market goes down (this risk may be greater in the short term) o Value or Mid-Cap stocks fall out of favor with investors o The Fund's assets remain undervalued or do not have the potential value originally expected Each Fund also has risks associated with investing in mid-size companies. Compared to large companies, mid-size companies, and the market for their equity securities, are likely to: o Be more sensitive to changes in earnings results and investor expectations o Have more limited product lines and capital resources o Experience sharper swings in market values o Be harder to sell at the times and prices the adviser/subadviser thinks appropriate o Offer greater potential for gain or loss Investing in non-U.S. issuers may involve unique risks compared to investing in securities of U.S. issuers. These risks may include: 9 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, the adviser/subadviser might 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 In addition, at times, more than 25% of Pioneer Mid Cap Value Fund's assets may be invested in the same market segment, such as financial or technology. To the extent the Fund emphasizes 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. Past Performance Set forth below is performance information for each Fund. The bar charts show how each Fund's total return (not including any deduction for sales charges) has varied from year to year for each full calendar year. The tables show average annual total return (before and after 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 bar charts give an indication of the risks of investing in each Fund, including the fact that you could incur a loss and experience volatility of returns year to year. Past performance before and after taxes does not indicate future results.

The table above shows the impact of taxes on AmSouth Mid Cap Fund's returns. After-tax returns are only shown for Class A and Class I shares and may vary for Class B shares. The Fund's after-tax returns are calculated using the highest individual 11 federal marginal income tax rates and do not reflect the impact of state and local taxes. In certain cases, the figure representing "Return After Taxes on Distributions and Sale of Fund Shares" may be higher than the other return figures for the same period. A higher after-tax return results when a capital loss occurs upon redemption and translates into an assumed tax deduction that benefits the shareholder. Please note that actual after-tax returns depend on an investor's tax situation and may differ from those shown. Also note that after-tax returns shown are not relevant to investors who hold their Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

(2) Sales charges may be reduced depending upon the amount invested or, in certain circumstances, waived. Class A shares bought as part of an investment of $1 million or more are not subject to an initial sales charge, but may be charged a CDSC of 1.00% if sold within one year of purchase. (3) For Class B shares purchased prior to the combination of AmSouth Funds with ISG Funds, the CDSC on such Class B shares held continuously declines over six years, starting with year one and ending in year seven from: 4%, 3%, 3%, 2%, 2%, 1%. For all other Class B shares held continuously, the CDSC declines over six years, starting with year one and ending in year seven from: 5%, 4%, 3%, 3%, 2%, 1%. Eight years after purchase (seven years in the case of shares acquired in the ISG combination), Class B shares automatically convert to Class A shares. 13 (4) To discourage short-term trading, a redemption fee of 2.00% will be charged on sales or exchanges of Class A, Class B and Class I shares of your AmSouth Fund made within 7 days of the date of purchase. A wire transfer fee of $7.00 will be deducted from the amount of your redemption if you request a wire transfer. (5) Other expenses for your AmSouth Fund are being limited to 0.20% for Class A shares, 0.20% for Class B shares and 0.05% for Class I shares. Any fee waiver or expense reimbursement arrangement is voluntary and may be discontinued at any time. (6) Purchases of $1 million or more and purchases by participants in certain group plans are not subject to an initial sales charge but may be subject to a contingent deferred sales charge of 1%. (7) At current asset levels, Pioneer Mid Cap Value Fund pays a management fee that ranges from 0.60% to 0.80% of average daily net assets based on its performance and the size of the Fund. The Fund's basic fee, before any performance adjustment, is 0.70% of average daily net assets, which is reduced at asset levels above $500 million. (8) Pioneer Mid Cap Value Fund's total annual operating expenses in the table have not been reduced by any expense offset arrangements. The hypothetical example below helps you compare the cost of investing in each Fund. It assumes that: (a) you invest $10,000 in each Fund for the time periods shown, (b) you reinvest all dividends and distributions, (c) your investment has a 5% return each year, and (d) each Fund's gross operating expenses remain the same. The examples are for comparison purposes only and are not a representation of either Fund's actual expenses or returns, either past or future. - ------------------------------------------------------------------------------------------------------------ Number of years you AmSouth Mid Cap Fund Pioneer Mid Cap Value Fund Combined Fund own your shares (Pro Forma) - ------------------------------------------------------------------------------------------------------------ Class A - ------------------------------------------------------------------------------------------------------------ Year 1 $701 $689 $689 - ------------------------------------------------------------------------------------------------------------ Year 3 $1,018 $931 $931 - ------------------------------------------------------------------------------------------------------------ Year 5 $1,358 $1,202 $1,192 - ------------------------------------------------------------------------------------------------------------ Year 10 $2,135 $1,957 $1,935 - ------------------------------------------------------------------------------------------------------------ Class B -- assuming redemption at end of period - ------------------------------------------------------------------------------------------------------------ Year 1 $743 $616 $616 - ------------------------------------------------------------------------------------------------------------ Year 3 $1,048 $967 $967 - ------------------------------------------------------------------------------------------------------------ Year 5 $1,480 $1,244 $1,244 - ------------------------------------------------------------------------------------------------------------ Year 10 $2,530 $2,222 $2,222 - ------------------------------------------------------------------------------------------------------------ Class B -- assuming no redemption - ------------------------------------------------------------------------------------------------------------ Year 1 $243 $216 $79 - ------------------------------------------------------------------------------------------------------------ Year 3 $748 $667 $246 - ------------------------------------------------------------------------------------------------------------ Year 5 $1,280 $1,144 $1,144 - ------------------------------------------------------------------------------------------------------------ Year 10 $2,530 $2,222 $2,222 - ------------------------------------------------------------------------------------------------------------ Class I Class Y - ------------------------------------------------------------------------------------------------------------ Year 1 $146 $216 $79 - ------------------------------------------------------------------------------------------------------------ Year 3 $452 $667 $246 - ------------------------------------------------------------------------------------------------------------ Year 5 $782 $1,144 $428 - ------------------------------------------------------------------------------------------------------------ Year 10 $1,713 $2,222 $954 - ------------------------------------------------------------------------------------------------------------ Reasons for the Proposed Reorganization The Trustees believe that the proposed Reorganization is in the best interests of AmSouth Mid Cap Fund. The Trustees considered the following matters, among others, in approving the proposal. 14 First, AAMI, the investment adviser to your Amsouth Fund, informed the Trustees that it does not intend to continue to provide investment advisory services to the AmSouth Funds. Consequently, a change in your AmSouth Fund's investment adviser was necessary. In the absence of the Reorganization, such a change would be more likely to motivate shareholders invested in reliance on AAMI's role to withdraw from the Fund, thereby reducing fund size and increasing fund expense ratios. Second, after the Reorganization, the combined Fund will have an asset size substantially larger than that of your AmSouth Fund, which may allow the combined Fund to achieve significant economies of scale in investments or expenses. Third, the historical investment performance of Pioneer Mid Cap Value Fund is superior to your AmSouth Fund's investment performance. For the one and five year periods ended December 31, 2004, Class A shares of Pioneer Mid Cap Value Fund had an average annual return of 14.68% (one year) and 11.40% (five year), compared to an average annual return of the Class A shares of your AmSouth Fund of 9.46% (one year) and -5.05% (five year) during the same period. The Trustees also considered that, for the one and five year periods ended March 31, 2005, Class A shares of the Pioneer Fund had an average annual return of 17.73% (one year) and 12.59% (five year), compared to an average annual return of the Class A shares of your AmSouth Fund of 10.15% (one year) and -6.37% (five year), respectively, during the same period. In addition, the Trustees considered the track record of Pioneer in managing equity and fixed income mutual funds. Fourth, the resources of Pioneer. At December 31, 2004, Pioneer managed over 80 investment companies and accounts with approximately $42 billion in assets, including $26.7 billion in equity funds. Pioneer is part of the global asset management group of UniCredito Italiano S.p.A., one of the largest banking groups in Italy, providing investment management and financial services to mutual funds, institutional and other clients. As of December 31, 2004, assets under management of UniCredito Italiano S.p.A. were approximately $175 billion worldwide. Shareholders of your AmSouth Fund would become part of a significantly larger family of funds that offers a more diverse array of investment options and enhanced shareholder account options. The Pioneer family of mutual funds offers over 80 funds, including domestic and international equity and fixed income funds and a money market fund that will be available to your AmSouth Fund's shareholders through exchanges Fifth, Pioneer Mid Cap Value Fund's management fee (0.74% of average daily net assets) is substantially lower than the advisory fee of your Fund (0.90% of average daily net assets). The aggregate Rule 12b-1 distribution and shareholder servicing fees and non-Rule 12b-1 shareholder servicing fees paid by the Class A and Class B shares of both Funds are the same. Moreover, your AmSouth Fund's Class I shares pay a non 12b-1 shareholder servicing fee that is not paid by the Pioneer Fund's Class Y shares. Currently, the Pioneer Mid Cap Value Fund's gross expense ratio is below the gross expense ratio of the corresponding class of your AmSouth Fund. However, your current expense ratio net of expense limitations is lower than the gross expense ratio of the Pioneer Fund (except for the Class Y shares of the Pioneer Fund, both the gross and net expenses of which are lower than the expenses of the Class I shares of the AmSouth Fund). On a pro forma basis, after giving effect to the Reorganization, it is estimated that the gross expenses of each class of the Pioneer Fund will be lower than the gross expenses of the corresponding class of your Fund. Although the net expenses of the Pioneer Fund's Class A and Class B shares will be higher than the net expenses of your Fund's Class A and Class B shares, your Fund's expense limitation is voluntary and may be discontinued at any time. AAMI has informed the trustees that the expense limitations will be discontinued in the future. The Trustees also noted that the Pioneer Fund is more actively managed, while the AmSouth Fund is an enhanced index fund, and index funds traditionally have substantially lower fees than actively managed funds. In addition, the broader distribution arrangements of the Pioneer Fund offer greater potential for further asset growth and reduced per share expenses. Sixth, the substantially larger size of the combined Pioneer Mid Cap Value Fund will offer greater opportunity for diversification of the investment portfolio, which should help to reduced risks. Seventh, the Class A, B and Y shares of Pioneer Mid Cap Value Fund received in the Reorganization will provide AmSouth Mid Cap Fund shareholders with exposure to substantially the same investment product as they currently have. Eighth, the transaction is structured to qualify as a tax-free reorganization under Section 368(a) of the Internal Revenue Code of 1986 and therefore will not be treated as a taxable sale of your AmSouth shares. Although the Reorganization will result in a per share increase in net unrealized capital gains and a decrease in capital loss carryforwards, the potential negative tax consequences of these aspects of the Reorganization are outweighed by the advantages of the Reorganization. 15 Pioneer and AmSouth Bank will pay all costs of preparing and printing the Funds' proxy statements and solicitation costs incurred by the Funds in connection with the Reorganization. AAMI will otherwise be responsible for all costs and expenses of the AmSouth Fund in connection with the Reorganizations. The Trustees also considered that Pioneer and AmSouth Bank will benefit from the Reorganization. See "Will Pioneer and AmSouth Bank Benefit from the Reorganizations." The Board of Trustees of the Pioneer Fund also considered that the Reorganization presents an excellent opportunity for the Pioneer Fund to acquire investment assets 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 the Pioneer Fund and its shareholders. CAPITALIZATION The following table sets forth the capitalization of each Fund as of May 31, 2005, and the pro forma combined Fund as of May 31, 2005. - ------------------------------------------------------------------------------------------------------------------------------ AmSouth Mid Cap Pioneer Mid Cap Value Pro Forma Pioneer Mid Fund Fund Cap Value Fund May 31, 2005 May 31, 2005 May 31, 2005 - ------------------------------------------------------------------------------------------------------------------------------ Total Net Assets (in thousands) $234,876 $2,460,056 $2,694,932 - ------------------------------------------------------------------------------------------------------------------------------ Class A shares ................................... $23,363 $1,911,174 $1,934,538 - ------------------------------------------------------------------------------------------------------------------------------ Class B shares ................................... $7,918 $208,901 $216,819 - ------------------------------------------------------------------------------------------------------------------------------ Class I/Y shares ................................. $203,595 $114,061 $317,656 - ------------------------------------------------------------------------------------------------------------------------------ Net Asset Value Per Share - ------------------------------------------------------------------------------------------------------------------------------ Class A shares ................................... $14.24 $25.22 $25.22 - ------------------------------------------------------------------------------------------------------------------------------ Class B shares ................................... $13.61 $22.57 $22.57 - ------------------------------------------------------------------------------------------------------------------------------ Class I/Y shares ................................. $14.30 $26.01 $26.01 - ------------------------------------------------------------------------------------------------------------------------------ Shares Outstanding - ------------------------------------------------------------------------------------------------------------------------------ Class A shares ................................... 1,641,062 75,781,678 76,708,079 - ------------------------------------------------------------------------------------------------------------------------------ Class B shares ................................... 581,591 9,254,911 9,605,706 - ------------------------------------------------------------------------------------------------------------------------------ Class I/Y shares ................................. 14,234,921 4,385,193 12,212,598 - ------------------------------------------------------------------------------------------------------------------------------ It is impossible to predict how many shares of the Pioneer Fund will actually be received and distributed by your AmSouth Fund on the Reorganization date. The table should not be relied upon to determine the amount of the Pioneer Fund's shares that will actually be received and distributed. 16 BOARD'S EVALUATION AND RECOMMENDATION For the reasons described above, the Trustees, including the Independent Trustees, approved the Reorganization. In particular, the Trustees determined that the Reorganization is in the best interests of your AmSouth Fund. Similarly, the Board of Trustees of the Pioneer Fund, including its Independent Trustees, approved the Reorganization. They also determined that the Reorganization is in the best interests of the Pioneer Fund. The Trustees recommend that the shareholders of your AmSouth Fund vote FOR the proposal to approve the Agreement and Plan of Reorganization. 17 AmSouth Small Cap Fund and Pioneer Growth Opportunities Fund PROPOSAL 1(f) Approval of Agreement and Plan of Reorganization 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-1, because it contains details that are not in the summary.

Pioneer Growth Opportunities Fund may invest up to 20% of its total assets in debt securities of U.S. corporate and government issuers. Generally, the Fund acquires debt securities that are investment grade, but the Fund may invest up to 5% of its net assets in below investment grade debt securities including below investment grade convertible debt securities.

You could lose money on your investment in either Fund or not make as much as if you invested elsewhere if: o The stock market goes down o Small company or growth stocks fall out of favor with investors o The adviser's/subadviser's judgment about the attractiveness, growth potential or potential appreciation of a particular stock proves incorrect Each Fund also has risks associated with investing in small companies. Compared to large companies, small companies, and the market for their equity securities, are likely to: 8 o Be more sensitive to changes in the economy, earnings results and investor expectations o Have more limited product lines and capital resources o Experience sharper swings in market values o Be harder to sell at the times and prices the adviser or subadviser thinks appropriate o Offer greater potential for gain or loss Investing in non-U.S. issuers may involve unique risks compared to investing in securities of U.S. issuers. These risks are more pronounced to the extent the Fund invests in issuers in countries with emerging markets or if the Fund invests significantly in one 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, the adviser/subadviser might 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 In addition, at times, more than 25% of Pioneer Growth Opportunities Fund's assets may be invested in the same market segment, such as financial or technology. To the extent the Fund emphasizes 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. Past Performance Set forth below is performance information for each Fund. The bar charts show how each Fund's total return (not including any deduction for sales charges) has varied from year to year for each full calendar year. The tables show average annual total return (before and after 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 bar charts give an indication of the risks of investing in each Fund, including the fact that you could incur a loss and experience volatility of returns year to year. Past performance before and after taxes does not indicate future results. 9 AmSouth Small Cap Fund -- Class A Shares Calendar Year Total Returns* [DATA BELOW IS REPRESENTED BY A BAR CHART IN THE ORIGINAL REPORT]] 1999 2000 2001 2002 2003 2004 15.97 18.68 -27.81 -26.75 34.42 13.89 * During the period shown in the bar chart, your AmSouth Fund's highest quarterly return was 27.37% for the quarter ended December 31, 1999, and the lowest quarterly return was -20.17% for the quarter ended September 30, 2001.

Pursuant to an agreement and plan of reorganization, Pioneer Growth Opportunities Fund's Investor Class acquired all of the assets and those liabilities reflected in the net assets of Safeco Growth Opportunities Fund (the predecessor fund) on December 10, 2004. In the reorganization, the predecessor fund exchanged all of its assets for Investor Class shares of the Fund. The predecessor fund offered an Investor Class and other classes of shares similar to the Fund's Class A, B and C shares. As a result of the reorganization, Pioneer Growth Opportunities Fund is the accounting successor of the predecessor fund. The predecessor fund operated as a registered investment company like the Fund. The performance of each class of the Fund 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). If all the expenses of Pioneer Growth Opportunities Fund were reflected, the performance would be lower. Since August 2, 2004 and prior to the reorganization, Pioneer served as the predecessor fund's investment adviser. Previously, Safeco Asset Management Company served as the predecessor fund's investment adviser. The Fund's Investor Class shares are not offered in the Reorganization. 10 AmSouth Small Cap Fund Average Annual Total Returns as of December 31, 2004 - --------------------------------------------------------------------------------------------------------------------------- 1 Year 5 Years Since Inception (3/2/98) - --------------------------------------------------------------------------------------------------------------------------- AmSouth Small Cap Fund, Class A Shares(1) - --------------------------------------------------------------------------------------------------------------------------- Return Before Taxes 7.65% -1.91% -0.12% - --------------------------------------------------------------------------------------------------------------------------- Return After Taxes on 7.65% -2.59% -0.63% Distributions - --------------------------------------------------------------------------------------------------------------------------- Return After Taxes on 4.97% -1.96% -0.37% Distributions and Sale of Fund Shares - --------------------------------------------------------------------------------------------------------------------------- AmSouth Small Cap Fund, Class B Shares(1) - --------------------------------------------------------------------------------------------------------------------------- Return Before Taxes 8.02% -1.89% -0.09% - --------------------------------------------------------------------------------------------------------------------------- AmSouth Small Cap Fund, Class I Shares(1) - --------------------------------------------------------------------------------------------------------------------------- Return Before Taxes 13.95% -0.65% 0.85% - --------------------------------------------------------------------------------------------------------------------------- Return After Taxes on 13.95% -1.34% 0.34% Distributions - --------------------------------------------------------------------------------------------------------------------------- Return After Taxes on 9.06% -0.91% 0.46% Distributions and Sale of Fund Shares - --------------------------------------------------------------------------------------------------------------------------- Russell 2000 Growth Index(2) 14.31% -3.57% 1.77% (reflects no deduction for fees, expenses or taxes) - --------------------------------------------------------------------------------------------------------------------------- (1) Class A, B and I shares were first offered on 3/2/98.

The table above shows the impact of taxes on AmSouth Small Cap Fund's returns. After-tax returns are only shown for Class A and Class I shares and may vary for Class B shares. The Fund's after-tax returns are calculated using the highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. In certain cases, the figure representing "Return After Taxes on Distributions and Sale of Fund Shares" may be higher than the other return figures for the same period. A higher after-tax return results when a capital loss occurs upon redemption and translates into an assumed tax deduction that benefits the shareholder. Please note that actual after-tax returns depend on an investor's tax situation and may differ from those shown. Also note that after-tax returns shown are not relevant to investors who hold their Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

Actual after-tax returns depend on your situation and may differ from those shown, and the after-tax returns shown are not relevant to shareholders who hold Fund shares through tax-deferred arrangements such as 401(k) plans or IRA accounts, or to investors that are tax-exempt. The most recent portfolio manager's discussion of each Fund's performance is attached as Exhibit C. 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 the AmSouth Small Cap Fund, the expenses of AmSouth Small Cap Fund for the period ended January 31, 2005, and (ii) for Pioneer Growth Opportunities Fund, the expenses of Pioneer Growth Opportunities Fund for the period ended December 31, 2004. 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, 2004. - --------------------------------------------------------------------------------------------------------------------- Shareholder AmSouth Pioneer Combined AmSouth Pioneer Combined AmSouth Combined transaction Small Cap Growth Fund (Pro Small Cap Growth Fund (Pro Small Cap Fund (Pro fees (paid Fund(1) Opportunities Forma) Fund(1) Opportunities Forma) Fund(1) Forma) directly from Fund Fund your investment) Class A Class A Class A Class B Class B Class B Class I Class Y(10) - --------------------------------------------------------------------------------------------------------------------- Maximum sales 5.50%(2) 5.75% 5.75% None None None None None charge (load) when you buy shares as a percentage of offering price - --------------------------------------------------------------------------------------------------------------------- Maximum None None(6) None 5.00%(3) 4.00% 4.00% None None deferred sales charge (load) as a percentage of purchase price or the amount you receive when you sell shares, whichever is less - --------------------------------------------------------------------------------------------------------------------- Redemption 2.00%(4) None None 2.00%(4) None None 2.00%(4) None fees - --------------------------------------------------------------------------------------------------------------------- Annual fund operating expenses (deducted from fund assets) (as a % of average net assets) - --------------------------------------------------------------------------------------------------------------------- Management fee 0.90% 0.65% 0.65% 0.90% 0.65% 0.65% 0.90% 0.65% - --------------------------------------------------------------------------------------------------------------------- 12 - --------------------------------------------------------------------------------------------------------------------- Distribution None 0.25% 0.25% 0.75% 1.00% 1.00% None None and service (12b-1) fee - --------------------------------------------------------------------------------------------------------------------- Other expenses 0.85%(5) 1.39%(7) 0.52% 1.11%(5) 0.68%(7) 0.48% 0.64%(5) 0.25% - --------------------------------------------------------------------------------------------------------------------- Total fund 1.75% 2.29%(8) 1.27% 2.76% 2.33%(8) 2.08% 1.54% 0.75% operating expenses - --------------------------------------------------------------------------------------------------------------------- Expense 0.28% 0.99%(9) N/A 0.54% 0.99%(9) N/A 0.22% N/A reimbursement/ reduction - --------------------------------------------------------------------------------------------------------------------- Net fund 1.47% 1.30% 1.27% 2.22% 1.34% 2.08% 1.32% 0.75% operating expenses - --------------------------------------------------------------------------------------------------------------------- (1) AmSouth Bank or other financial institutions may charge their customer account fees for automatic investment and other cash management services provided in connection with investment in the Fund. (2) Sales charges may be reduced depending upon the amount invested or, in certain circumstances, waived. Class A shares bought as part of an investment of $1 million or more are not subject to an initial sales charge, but may be charged a CDSC of 1.00% if sold within one year of purchase. (3) For Class B shares purchased prior to the combination of AmSouth Funds with ISG Funds, the CDSC on such Class B shares held continuously declines over six years, starting with year one and ending in year seven from: 4%, 3%, 3%, 2%, 2%, 1%. For all other Class B shares held continuously, the CDSC declines over six years, starting with year one and ending in year seven from: 5%, 4%, 3%, 3%, 2%, 1%. Eight years after purchase (seven years in the case of shares acquired in the ISG combination), Class B shares automatically convert to Class A shares. (4) To discourage short-term trading, a redemption fee of 2.00% will be charged on sales or exchanges of Class A, Class B and Class I shares of your AmSouth Fund made within 30 days of the date of purchase. A wire transfer fee of $7.00 will be deducted from the amount of your redemption if you request a wire transfer. (5) Other expenses for your AmSouth Fund are being limited to 0.57% for Class A shares, 0.57% for Class B shares and 0.42% for Class I shares. Any fee waiver or expense reimbursement arrangement is voluntary and may be discontinued at any time. (6) Purchases of $1 million or more and purchases by participants in certain group plans are not subject to an initial sales charge but may be subject to a contingent deferred sales charge of 1%. (7) Other expenses are based on estimated amounts for the current fiscal year. (8) Pioneer Growth Opportunities Fund's total annual operating expenses in the table have not been reduced by any expense offset arrangements. (9) The expenses in the table above reflect the expense limitation in effect through May 1, 2006 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 Class A expenses to 1.30% of the average daily net assets attributable to Class A shares; the portion of Fund expenses (including the amount of the management fee waived) attributable to Class B and Class Y shares will be reduced only to the extent such expenses are reduced for Class A shares. There can be no assurance that Pioneer will extend the expense limitation beyond May 1, 2006. (10) Class Y shares of Pioneer Growth Opportunities Fund are being offered for the first time in connection with the Reorganization. The hypothetical example below helps you compare the cost of investing in each Fund. It assumes that: (a) you invest $10,000 in each Fund for the time periods shown, (b) you reinvest all dividends and distributions, (c) your investment has a 5% return each year, and (d) each Fund's gross operating expenses remain the same. The examples are for comparison purposes only and are not a representation of either Fund's actual expenses or returns, either past or future. 13 - ------------------------------------------------------------------------------------------------------------ Number of years you AmSouth Small Cap Fund Pioneer Growth Opportunities Combined Fund own your shares Fund (Pro Forma) - ------------------------------------------------------------------------------------------------------------ Class A - ------------------------------------------------------------------------------------------------------------ Year 1 $718 $700 $696 - ------------------------------------------------------------------------------------------------------------ Year 3 $1,071 $1,160 $953 - ------------------------------------------------------------------------------------------------------------ Year 5 $1,447 $1,645 $1,229 - ------------------------------------------------------------------------------------------------------------ Year 10 $2,499 $2,977 $2,015 - ------------------------------------------------------------------------------------------------------------ Class B -- assuming redemption at end of period - ------------------------------------------------------------------------------------------------------------ Year 1 $779 $536 $611 - ------------------------------------------------------------------------------------------------------------ Year 3 $1,156 $932 $952 - ------------------------------------------------------------------------------------------------------------ Year 5 $1,659 $1,255 $1,219 - ------------------------------------------------------------------------------------------------------------ Year 10 $2,847 $2,580 $2,203 - ------------------------------------------------------------------------------------------------------------ Class B -- assuming no redemption - ------------------------------------------------------------------------------------------------------------ Year 1 $279 $136 $211 - ------------------------------------------------------------------------------------------------------------ Year 3 $856 $632 $652 - ------------------------------------------------------------------------------------------------------------ Year 5 $1,459 $1,155 $1,119 - ------------------------------------------------------------------------------------------------------------ Year 10 $2,847 $2,580 $2,203 - ------------------------------------------------------------------------------------------------------------ Class I Class Y - ------------------------------------------------------------------------------------------------------------ Year 1 $157 N/A $77 - ------------------------------------------------------------------------------------------------------------ Year 3 $486 N/A $240 - ------------------------------------------------------------------------------------------------------------ Year 5 $839 N/A $417 - ------------------------------------------------------------------------------------------------------------ Year 10 $1,834 N/A $931 - ------------------------------------------------------------------------------------------------------------ Reasons for the Proposed Reorganization The Trustees believe that the proposed Reorganization is in the best interests of AmSouth Small Cap Fund. The Trustees considered the following matters, among others, in approving the proposal. First, AAMI, the investment adviser to your AmSouth Fund, informed the Trustees that it does not intend to continue to provide investment advisory services to the AmSouth Funds. Consequently, a change in your AmSouth Fund's investment adviser was necessary. In the absence of the Reorganization, such a change would be more likely to motivate shareholders invested in reliance on AAMI's role to withdraw from the Fund, thereby reducing fund size and increasing fund expense ratios. Second, after the Reorganization, the combined Fund will have an asset size substantially larger than that of your AmSouth Fund, which may allow the combined Fund to achieve significant economies of scale in investments or expenses. Third, the historical investment performance of Pioneer Growth Opportunities Fund exceeds your AmSouth Fund's investment performance. For the one and five year periods ended December 31, 2004, Class A shares of Pioneer Growth Opportunities Fund had an average annual return of 15.19% (one year); and 3.88% (five year); compared to an average annual return of the Class A shares of your AmSouth Fund of 7.65% (one year); and -1.91% (five year), respectively, during the same period. In addition, the Trustees considered the track record of Pioneer in managing equity and fixed income mutual funds. Fourth, the resources of Pioneer. At December 31, 2004, Pioneer managed over 80 investment companies and accounts with approximately $42 billion in assets. Pioneer is part of the global asset management group of UniCredito Italiano S.p.A., one of the largest banking groups in Italy, providing investment management and financial services to mutual funds, institutional and other clients. As of December 31, 2004, assets under management of UniCredito Italiano S.p.A. were approximately $175 billion worldwide. Shareholders of your AmSouth Fund would become part of a significantly larger family of funds that offers a more diverse array of investment options and enhanced shareholder account options. The Pioneer family of mutual funds offers over 80 funds, including domestic and international equity and fixed income funds and a money market fund that will be available to your AmSouth Fund's shareholders through exchanges. Fifth, Pioneer Fund's management fee (0.65% of average daily net assets) is substantially lower than the advisory fee of your Fund (0.90% of average daily net assets). Although the historical gross expenses of Class A shares of Pioneer Growth 14 Opportunities Fund are higher than your Fund's historical gross expenses for Class A shares, the historical gross and net expenses for Class B shares of the Pioneer Fund, and estimated pro forma expenses of the Pioneer Fund attributable to Class A, B and Y shares after giving effect to the Reorganization on both a gross and net basis are lower than your Fund's gross and net operating expenses. The aggregate Rule 12b-1 distribution and shareholder servicing fees and non-Rule 12b-1 shareholder servicing fees paid by the Class A and Class B shares of both Funds are the same. Moreover, your AmSouth Fund's Class I shares pay a non 12b-1 shareholder servicing fee that is not paid by the Pioneer Fund's Class Y shares. In addition, the broader distribution arrangements of the Pioneer Fund offer greater potential for further asset growth and reduced per share expenses. Sixth, the substantially larger size of the combined Pioneer Growth Opportunities Fund will offer greater opportunity for diversification of the investment portfolio, which should help to reduce risks. Seventh, the Class A, B and Y shares of Pioneer Growth Opportunities Fund received in the Reorganization will provide AmSouth Small Cap Fund shareholders with exposure to substantially the same investment product as they currently have. Eighth, the transaction is structured to qualify as a tax-free reorganization under Section 368(a) of the Internal Revenue Code of 1986 and therefore will not be treated as a taxable sale of your AmSouth shares. Pioneer and AmSouth Bank will pay all costs of preparing and printing the Funds' proxy statements and solicitation costs incurred by the Funds in connection with the Reorganization. AAMI will otherwise be responsible for all costs and expenses of the AmSouth Fund in connection with the Reorganizations. The Trustees also considered that Pioneer and AmSouth Bank will benefit from the Reorganization. See "Will Pioneer and AmSouth Bank Benefit from the Reorganizations." The Board of Trustees of the Pioneer Fund also considered that the Reorganization presents an excellent opportunity for the Pioneer Fund to acquire investment assets 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 the Pioneer Fund and its shareholders. CAPITALIZATION The following table sets forth the capitalization of each Fund as of May 31, 2005, and the pro forma combined Fund as of May 31, 2005. - ------------------------------------------------------------------------------------------------------------------------------------ Pioneer Growth Pro Forma Pioneer AmSouth Small Cap Opportunities Growth Opportunities Fund Fund Fund May 31, 2005 May 31, 2005 May 31, 2005 - ------------------------------------------------------------------------------------------------------------------------------------ Total Net Assets (in thousands) $257,277 $450,076 $707,352 - ------------------------------------------------------------------------------------------------------------------------------------ Class A shares ................................... $10,487 $31,515 $42,002 - ------------------------------------------------------------------------------------------------------------------------------------ Class B shares ................................... $2,523 $338 $2,861 - ------------------------------------------------------------------------------------------------------------------------------------ Class I/Y shares ................................. $244,267 N/A $244,267 - ------------------------------------------------------------------------------------------------------------------------------------ Net Asset Value Per Share - ------------------------------------------------------------------------------------------------------------------------------------ Class A shares ................................... $9.18 $28.16 $28.16 - ------------------------------------------------------------------------------------------------------------------------------------ Class B shares ................................... $8.67 $26.32 $26.32 - ------------------------------------------------------------------------------------------------------------------------------------ Class I/Y shares ................................. $9.32 N/A $28.16 - ------------------------------------------------------------------------------------------------------------------------------------ Shares Outstanding - ------------------------------------------------------------------------------------------------------------------------------------ Class A shares ................................... 1,142,354 1,119,263 1,491,720 - ------------------------------------------------------------------------------------------------------------------------------------ Class B shares ................................... 290,839 12,846 108,684 - ------------------------------------------------------------------------------------------------------------------------------------ Class I/Y shares ................................. 26,215,302 N/A 8,675,149 - ------------------------------------------------------------------------------------------------------------------------------------ It is impossible to predict how many shares of the Pioneer Fund will actually be received and distributed by your AmSouth Fund on the Reorganization date. The table should not be relied upon to determine the amount of the Pioneer Fund's shares that will actually be received and distributed. 15 BOARD'S EVALUATION AND RECOMMENDATION For the reasons described above, the Trustees, including the Independent Trustees, approved the Reorganization. In particular, the Trustees determined that the Reorganization is in the best interests of your AmSouth Fund. Similarly, the Board of Trustees of the Pioneer Fund, including its Independent Trustees, approved the Reorganization. They also determined that the Reorganization is in the best interests of the Pioneer Fund. The Trustees recommend that the shareholders of your AmSouth Fund vote FOR the proposal to approve the Agreement and Plan of Reorganization. 16 AmSouth International Equity Fund and Pioneer International Core Equity Fund PROPOSAL 1(g) Approval of Agreement and Plan of Reorganization 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-2, because it contains details that are not in the summary. Each Fund invests in securities of international issuers and, consequently, each Fund has similar investment policies and risks.

The Fund intends to invest in the stocks of large companies in countries with developed markets. Under normal market conditions, the Fund intends to invest in companies organized or having a majority of their assets in or deriving a majority of their operating income in at least three non-U.S. countries, and no more than 40% of the Fund's assets are invested in such companies in any one country. Dimensional determines company size on a country or region specific basis and based primarily on market capitalization. In the countries or regions authorized for investment, the subadviser first ranks eligible companies listed on selected exchanges based on the companies' market capitalizations. Dimensional then determines the universe of eligible stocks by defining the minimum market capitalization of a large company that may be purchased by the Fund with respect to each country or region. As of the date of this Proxy Statement/Prospectus, on an aggregate basis for the Fund, Dimensional considers large companies to be those companies with a market capitalization of at least $716 million. This threshold will vary by country or region and will change with market conditions. - ------------------------------------------------------------------------------------------------------------------------------------ 2 - ------------------------------------------------------------------------------------------------------------------------------------ AmSouth International Equity Fund Pioneer International Core Equity Fund - ------------------------------------------------------------------------------------------------------------------------------------ Investment strategies Dimensional believes that equity investing Pioneer International Core Equity Fund uses a should involve a long-term view and a focus "growth at a reasonable price" style of on asset class selection, not stock picking. management.

Dimensional, using this approach and its best judgment, will seek to set country or region weights based on the relative market capitalization of eligible large companies within each country or region. When investing on a market capitalization weighted basis, Dimensional will use a market capitalization weighted approach which may include adjusting that weighting to consider such factors as free float, trading strategies, liquidity management and other factors that Dimensional determines appropriate, given market conditions. As a result, the weighting of certain countries in the Fund's portfolio may vary from their weighting in international indices such as those published by FTSE International, Morgan Stanley Capital - ------------------------------------------------------------------------------------------------------------------------------------ 3 - ------------------------------------------------------------------------------------------------------------------------------------ AmSouth International Equity Fund Pioneer International Core Equity Fund - ------------------------------------------------------------------------------------------------------------------------------------ International or Salomon/Smith Barney. - ------------------------------------------------------------------------------------------------------------------------------------ Other investments The Fund is not required to invest The Fund may invest up to 20% of its total exclusively in common stocks or other equity assets in debt securities, cash and cash securities, and, if deemed advisable, the equivalents.

Ratings, or, if unrated, deemed to be of comparable quality by AAMI. Debt securities are subject to the risk of an issuer's inability to meet principal or interest payments on its obligations. Factors which could contribute to a decline in the market value of debt securities in the Fund's portfolio include rising interest rates or a reduction in the perceived creditworthiness of the issuer of the securities. 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. - ------------------------------------------------------------------------------------------------------------------------------------ Temporary defensive strategies When AAMI determines adverse market Pioneer International Core Equity Fund may conditions exist, AmSouth International invest all or part of its assets in Equity Fund may invest entirely in cash securities with remaining maturities of less positions, directly in U.S. Government than one year, cash equivalents or may hold securities and short-term paper, such as cash. bankers' acceptances. - ------------------------------------------------------------------------------------------------------------------------------------ Diversification AmSouth International Equity Fund is Pioneer International Core Equity Fund is non-diversified for the purpose of the diversified for the purpose of the Investment Investment Company Act and, therefore, may Company Act and is subject to diversification concentrate its investments in a limited requirements under the Internal Revenue Code number of issuers. of 1986, as amended (the "Code").

The fee will be charged on all covered redemptions and exchanges, including those made through retirement plan, brokerage and other types of omnibus accounts (except where it is not practical for the plan administrator or brokerage firm to implement the fee).

You could lose money on your investment in either Fund or not make as much as if you invested elsewhere if: o The non-U.S. stock markets go down or perform poorly relative to other investments (this risk may be greater in the short term) o Equity securities of non-U.S. issuers or growth stocks fall out of favor with investors o The Fund's investments do not have the growth potential originally expected Each Fund may be subject to the following additional risks associated with investing in non-U.S. issuers, which may involve unique risks compared to investing in securities of U.S. issuers. These risks are more pronounced to the extent the Funds invests in issuers in countries with emerging markets or if the Funds invest significantly in one 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, the adviser/subadviser might 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 In addition, at times, more than 25% of Pioneer International Core Equity Fund's assets may be invested in the same market segment, such as financial or technology. To the extent the Fund emphasizes 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. 10 AmSouth International Equity Fund is subject to risks relating to the fact that it is non-diversified. The Fund may invest in a small number of companies which may increase the volatility of the Fund. Accordingly, the Fund's portfolio may be more sensitive to changes in the market value of a single company or industry. AmSouth International Equity Fund may trade securities actively to achieve its principal investment strategies. Active trading of portfolio securities could increase the Fund's transaction costs (thereby lowering its performance) and may increase the amount of taxes that you pay (on distributions of net gains realized on those trades). Past Performance Set forth below is performance information for AmSouth International Equity Fund. The bar charts show how your AmSouth Fund's total return (not including any deduction for sales charges) has varied from year to year for each full calendar year. The tables show average annual total return (before and after taxes) for your AmSouth Fund over time for each class of shares (including deductions for sales charges) compared with a broad-based securities market index. The bar charts give an indication of the risks of investing in your AmSouth Fund, including the fact that you could incur a loss and experience volatility of returns year to year. Past performance before and after taxes does not indicate future results. Pioneer International Core Equity Fund has not commenced investment operations.

The predecessor funds were managed using substantially the same investment objective, policies and methodologies as the Fund. Class A shares were first offered on 8/15/97. Performance for the Class B shares, which were first offered on 2/2/99, is based on the historical performance of the Fund's Class A shares, including the performance of the predecessor funds, (without sales charge) prior to that date. The historical performance of the Class B shares has been restated to reflect the Fund's Class B distribution (12b-1) fees and the contingent deferred sales charge. (2) The quoted returns reflect the performance from 8/15/97 to 12/13/98 of the DG International Equity Fund and from 12/14/98 to 3/12/00 of the ISG International Equity Fund, which were open-end investment companies that were the predecessor funds to the International Equity Fund. The predecessor funds were managed using substantially the same investment objective, policies and methodologies as the Fund Performance for the Class I shares, which were first offered on 12/14/98, is based on the historical performance of the Fund's Class A shares, including the performance of the predecessor funds (without sales charge) prior to that date. (3) The Morgan Stanley Capital International Europe, Australasia, Far East Index ("MSCI EAFE Index"), an unmanaged, capitalization weighted index of 21 international markets, is for reference only, does not mirror the Fund's investments, and reflects no deduction for fees, expenses or taxes and was calculated from 7/31/97. The above table shows the impact of taxes on the AmSouth International Equity Fund's returns. After-tax returns are only shown for Class A shares and may vary for Class B shares. The Fund's after-tax returns are calculated using the highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. In certain cases, the figure representing "Return After Taxes on Distributions and Sale of Fund Shares" may be higher than the other return figures for the same period. A higher after-tax return results when a capital loss occurs upon redemption and translates into an assumed tax deduction that benefits the shareholder. Please note that actual after-tax returns depend on an investor's tax situation and may differ from those shown. Also note that after-tax returns shown are not relevant to investors who hold their Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts. The most recent portfolio manager's discussion of your AmSouth Fund's performance is attached as Exhibit C.

(2) Sales charges may be reduced depending upon the amount invested or, in certain circumstances, waived. Class A shares bought as part of an investment of $1 million or more are not subject to an initial sales charge, but may be charged a CDSC of 1.00% if sold within one year of purchase. (3) For Class B shares purchased prior to the combination of AmSouth Funds with ISG Funds, the CDSC on such Class B shares held continuously declines over six years, starting with year one and ending in year seven from: 4%, 3%, 3%, 2%, 2%, 1%. For all other Class B shares held continuously, the CDSC declines over six years, starting with year one and ending in year seven from: 5%, 4%, 3%, 3%, 2%, 1%. Eight years after purchase (seven years in the case of shares acquired in the ISG combination), Class B shares automatically convert to Class A shares. (4) To discourage short-term trading, a redemption fee of 2.00% will be charged on sales or exchanges of Class A, Class B and Class I shares of your AmSouth Fund made within 30 days of the date of purchase. A wire transfer fee of $7.00 will be deducted from the amount of your redemption if you request a wire transfer. (5) Other expenses for your AmSouth Fund are being limited to 0.41% for Class A shares, 0.41% for Class B shares and 0.26% for Class I shares. Any fee waiver or expense reimbursement arrangement is voluntary and may be discontinued at any time. (6) The Pioneer Fund's total annual operating expenses in the table have not been reduced by any expense offset arrangements. The hypothetical example below helps you compare the cost of investing in each Fund. It assumes that: (a) you invest $10,000 in each Fund for the time periods shown, (b) you reinvest all dividends and distributions, (c) your investment has a 5% return each year, and (d) each Fund's gross operating expenses remain the same. The examples are for comparison purposes only and are not a representation of either Fund's actual expenses or returns, either past or future. 13 - ------------------------------------------------------------------------------------------------------------ Number of years you AmSouth International Equity Fund Pro Forma own your shares Pioneer International Core Equity Fund - ------------------------------------------------------------------------------------------------------------ Class A - ------------------------------------------------------------------------------------------------------------ Year 1 $713 $790 - ------------------------------------------------------------------------------------------------------------ Year 3 $1,056 $996 - ------------------------------------------------------------------------------------------------------------ Year 5 $1,422 $1,302 - ------------------------------------------------------------------------------------------------------------ Year 10 $2,448 $2,169 - ------------------------------------------------------------------------------------------------------------ Class B -- assuming redemption at end of period - ------------------------------------------------------------------------------------------------------------ Year 1 $783 $646 - ------------------------------------------------------------------------------------------------------------ Year 3 $1,168 $1,058 - ------------------------------------------------------------------------------------------------------------ Year 5 $1,679 $1,396 - ------------------------------------------------------------------------------------------------------------ Year 10 $2,865 $2,513 - ------------------------------------------------------------------------------------------------------------ Class B -- assuming no redemption - ------------------------------------------------------------------------------------------------------------ Year 1 $283 $246 - ------------------------------------------------------------------------------------------------------------ Year 3 $868 $758 - ------------------------------------------------------------------------------------------------------------ Year 5 $1,479 $1,296 - ------------------------------------------------------------------------------------------------------------ Year 10 $2,865 $2,513 - ------------------------------------------------------------------------------------------------------------ Class I Class Y - ------------------------------------------------------------------------------------------------------------ Year 1 $160 $112 - ------------------------------------------------------------------------------------------------------------ Year 3 $496 $350 - ------------------------------------------------------------------------------------------------------------ Year 5 $855 $606 - ------------------------------------------------------------------------------------------------------------ Year 10 $1,867 $1,340 - ------------------------------------------------------------------------------------------------------------ Reasons for the Proposed Reorganization The Trustees believe that the proposed Reorganization is in the best interests of Amsouth International Equity Fund. The Trustees considered the following matters, among others, in approving the proposal. First, AAMI, the investment adviser to your AmSouth Fund, informed the Trustees that it does not intend to continue to provide investment advisory services to the AmSouth Funds. Consequently, a change in your AmSouth Fund's investment adviser was necessary. In the absence of the Reorganization, such a change would be more likely to motivate shareholders invested in reliance on AAMI's role to withdraw from the Fund, thereby reducing fund size and increasing fund expense ratios. Second, the resources of Pioneer. At December 31, 2004, Pioneer managed over 80 investment companies and accounts with approximately $42 billion in assets. Pioneer is part of the global asset management group of UniCredito Italiano S.p.A., one of the largest banking groups in Italy, providing investment management and financial services to mutual funds, institutional and other clients. As of December 31, 2004, assets under management of UniCredito Italiano S.p.A. were approximately $175 billion worldwide. Shareholders of your AmSouth Fund would become part of a significantly larger family of funds that offers a more diverse array of investment options and enhanced shareholder account options. The Pioneer family of mutual funds offers over 80 funds, including domestic and international equity and fixed income funds and a money market fund that will be available to your AmSouth Fund's shareholders through exchanges. Third, the estimated pro forma expenses of the Pioneer Fund, after giving effect to the Reorganization, on a gross basis are lower than your AmSouth Fund's gross operating expenses. The Trustees recognized that the Pioneer Fund's operating expenses net of expense limitations, and its management fee, are higher than your Fund's expenses net of expense limitations and management fee (except for Class I shares, for which pro forma expenses of the Pioneer Fund's Class Y shares are estimated to be lower on both a gross and a net basis). However, the expense limitations on your AmSouth Fund are voluntary and may be discontinued at any time. In addition, the Trustees considered the positive factors associated with the Reorganization to outweigh the negative factors, such as the increase in expenses of the Pioneer Fund. The Trustees also considered that the aggregate Rule 12b-1 distribution and shareholder servicing fees and non-Rule 12b-1 shareholder servicing fees paid by the Class A and Class B shares of each Fund are the same. Moreover, your AmSouth Fund's Class I shares pay a non 12b-1 shareholder servicing fee that is not paid by the Pioneer Fund's Class Y shares. In addition, the broader distribution arrangements of the Pioneer Fund offer greater potential for further asset growth and reduced per share expenses. 14 Fourth, the Class A, B and Y shares of Pioneer International Core Equity Fund received in the Reorganization will provide AmSouth International Equity Fund shareholders with exposure to substantially the same investment product as they currently have. Fifth, the transaction is structured to qualify as a tax-free reorganization under Section 368(a) of the Internal Revenue Code of 1986 and therefore will not be treated as a taxable sale of your AmSouth shares. Pioneer and AmSouth Bank will pay all costs of preparing and printing the Funds' proxy statements and solicitation costs incurred by the Funds in connection with the Reorganization. AAMI will otherwise be responsible for all costs and expenses of the AmSouth Fund in connection with the Reorganizations. The Trustees also considered that Pioneer and AmSouth Bank will benefit from the Reorganization. See "Will Pioneer and AmSouth Bank Benefit from the Reorganizations." The Board of Trustees of the Pioneer Fund also considered that the Reorganization presents an excellent opportunity for the Pioneer Fund to acquire investment assets 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 the Pioneer Fund and its shareholders.

The table should not be relied upon to determine the amount of the Pioneer Fund's shares that will actually be received and distributed. BOARD'S EVALUATION AND RECOMMENDATION For the reasons described above, the Trustees, including the Independent Trustees, approved the Reorganization. In particular, the Trustees determined that the Reorganization is in the best interests of your AmSouth Fund. Similarly, the Board of Trustees of the Pioneer Fund, including its Independent Trustees, approved the Reorganization. They also determined that the Reorganization is in the best interests of the Pioneer Fund. 15 The Trustees recommend that the shareholders of your AmSouth Fund vote FOR the proposal to approve the Agreement and Plan of Reorganization. 16 AmSouth Select Equity Fund and Pioneer Focused Equity Fund PROPOSAL 1 (h) Approval of Agreement and Plan of Reorganization 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-2, because it contains details that are not in the summary. Each Fund has an investment objective of long-term capital growth and, consequently, the Funds have similar investment polices and risks.

You could lose money on your investment in either Fund or not make as much as if you invested elsewhere if: o The stock market goes down (this risk may be greater in the short term) o The market segment on which the Fund focuses - undervalued growth stocks - underperforms other kinds of investments or market averages o Value stocks fall out of favor with investors o The adviser's/subadviser's judgment about the attractiveness, growth potential or potential appreciation of a particular stock proves to be incorrect Each Fund is subject to risks relating to the fact that it is non-diversified. Each Fund may invest in a small number of companies which may increase the volatility of the Fund. Accordingly, each Fund's portfolio may be more sensitive to changes in the market value of a single company or industry. Each Fund may trade securities actively to achieve its principal investment strategies. Active trading of portfolio securities could increase the Fund's transaction costs (thereby lowering its performance) and may increase the amount of taxes that you pay (on distributions of net gains realized on those trades). However, the adviser/subadviser expects that the Fund's annual portfolio turnover rate will average less than 50% each year. If either Fund invests in securities with additional risk, that Fund's share price volatility accordingly could be greater and its performance lower. At times, more than 25% of the Pioneer Focused Equity Fund's assets may be invested in the same market segment, such as financials or technology. To the extent the Fund emphasizes 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. 9 Pioneer Focused Equity Fund may be subject to the following additional risks associated with investing in non-U.S. issuers, which 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 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 Past Performance Set forth below is performance information for AmSouth Select Equity Fund. The bar charts show how AmSouth Select Equity Fund's total return (not including any deduction for sales charges) has varied from year to year for each full calendar year. The tables show average annual total return for AmSouth Select Equity Fund over time for each class of shares compared with a broad-based securities market index. The bar charts give an indication of the risks of investing in AmSouth Select Equity Fund, including the fact that you could incur a loss and experience volatility of returns year to year.

Performance for the Class B shares, which were first offered on 9/2/98, is based on the historical performance of the Fund's Class A shares (without sales charge) prior to that date. The historical performance of the Class B shares has been restated to reflect the Fund's Class B shares distribution (12b-1) fees and the contingent deferred sales charge. 2 Performance for the Class I shares, which were first offered on 9/1/98, is based on the historical performance of the Fund's Class A shares (without sales charge) prior to that date. (3) The S&P 500 Index, a widely recognized, unmanaged index of 500 common stocks, is for reference only, does not mirror the Fund's investments, and reflects no deduction for fees, expenses or taxes. The table above shows the impact of taxes on the Fund's returns. After-tax returns are only shown for Class A shares and may vary for Class B shares. The Fund's after-tax returns are calculated using the highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. In certain cases, the figure representing "Return After Taxes on Distributions and Sale of Fund Shares" may be higher than the other return figures for the same period. A higher after-tax return results when a capital loss occurs upon redemption and translates into an assumed tax deduction that beneflts the shareholder. Please note that actual after-tax returns depend on an investor's tax situation and may differ from those shown. Also note that after-tax returns shown are not relevant to investors who hold their Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts. The most recent portfolio manager's discussion of AmSouth Select Equity Fund's performance is attached as Exhibit C.

The expenses in the table appearing below are based on (i) for the AmSouth Select Equity Fund, the expenses of AmSouth Select Equity Fund for the period ended January 31, 2005 and (ii) for the Pioneer Focused Equity Fund, the estimated pro forma annual expenses for the period ended May 31, 2005. 11 - ---------------------------------------------------------------------------------------------------------------------------- Shareholder AmSouth Select Pioneer Focused AmSouth Select Pioneer Focused AmSouth Select Pioneer Focused transaction Equity Fund(1) Equity Fund Equity Fund(1) Equity Fund Equity Fund(1) Equity Fund fees (paid (Pro Forma) (Pro Forma) (Pro forma) directly from your investment) Class A Class A Class B Class B Class I Class Y - ---------------------------------------------------------------------------------------------------------------------------- Maximum sales 5.50%(2) 5.75%(2) None None None None charge (load) when you buy shares as a percentage of offering price - ---------------------------------------------------------------------------------------------------------------------------- Maximum None None 5.00%(3) 4.00% None None deferred sales charge (load) as a percentage of purchase price or the amount you receive when you sell shares, whichever is less - ---------------------------------------------------------------------------------------------------------------------------- Redemption fees 2.00%(4) None 2.00%(4) None 2.00%(4) None - ---------------------------------------------------------------------------------------------------------------------------- Annual fund operating expenses (deducted from fund assets) (as a % of average net assets) - ---------------------------------------------------------------------------------------------------------------------------- Management fee 0.80% 0.65% 0.80% 0.65% 0.80% 0.65% - ---------------------------------------------------------------------------------------------------------------------------- Distribution None 0.25% 0.75% 1.00% None None and service (12b-1) fee - ---------------------------------------------------------------------------------------------------------------------------- Other expenses 0.60%(5) 0.27% 0.61%(5) 0.38% 0.46%(5) 0.14% - ---------------------------------------------------------------------------------------------------------------------------- Total fund 1.40% 1.17% (6) 2.16% 2.03% (6) 1.26% 0.79% (6) operating expenses - ---------------------------------------------------------------------------------------------------------------------------- Expense 0.11% N/A 0.12% N/A 0.12% N/A reimbursement/ reduction - ---------------------------------------------------------------------------------------------------------------------------- Net fund 1.29% 1.17% 2.04% 2.03% 1.14% 0.79% operating expenses - ---------------------------------------------------------------------------------------------------------------------------- (1) AmSouth Bank or other financial institutions may charge their customer account fees for automatic investment and other cash management services provided in connection with investment in the Fund. (2) Sales charges may be reduced depending upon the amount invested or, in certain circumstances, waived. Class A shares of the Pioneer Fund bought as part of an investment of $1 million or more are not subject to an initial sales charge, but may be charged a CDSC of 1.00% if sold within one year of purchase. (3) A CDSC on Class B shares held continuously declines over six years starting with year one and ending in year seven from: 5%, 4%, 3%, 3%, 2%, 1%. Eight years after purchase Class B shares automatically convert to Class A shares. (4) To discourage short-term trading, a redemption fee of 2.00% will be charged on sales or exchanges of Class A, Class B and Class I shares of your AmSouth Fund made within 7 days of the date of purchase. A wire transfer fee of $7.00 will be deducted from the amount of your redemption if you request a wire transfer. 12 (5) Other expenses for your AmSouth Fund are being limited to 0.49% for Class A shares, 0.49% for Class B shares and 0.34% for Class I shares. Any fee waiver or expense reimbursement arrangement is voluntary and may be discontinued at any time. (6) The Pioneer Fund's total annual operating expenses in the table have not been reduced by any expense offset arrangements. The hypothetical example below helps you compare the cost of investing in each Fund. It assumes that: (a) you invest $10,000 in each Fund for the time periods shown, (b) you reinvest all dividends and distributions, (c) your investment has a 5% return each year, (d) each Fund's gross operating expenses remain the same, and (e) the expense limitation for your Fund is in effect for year one. The examples are for comparison purposes only and are not a representation of either Fund's actual expenses or returns, either past or future. - ----------------------------------------------------------------------------------- Number of years you AmSouth Equity Select Fund Pro Forma own your shares Pioneer Focused Equity Fund - ----------------------------------------------------------------------------------- Class A - ----------------------------------------------------------------------------------- Year 1 $685 $687 - ----------------------------------------------------------------------------------- Year 3 $969 $925 - ----------------------------------------------------------------------------------- Year 5 $1,274 $1,182 - ----------------------------------------------------------------------------------- Year 10 $2,095 $1,194 - ----------------------------------------------------------------------------------- Class B --- assuming redemption at end of period - ----------------------------------------------------------------------------------- Year 1 $719 $606 - ----------------------------------------------------------------------------------- Year 3 $976 $937 - ----------------------------------------------------------------------------------- Year 5 $1,359 $1,193 - ----------------------------------------------------------------------------------- Year 10 $2,300 $2,137 - ----------------------------------------------------------------------------------- Class B --- assuming no redemption - ----------------------------------------------------------------------------------- Year 1 $219 $206 - ----------------------------------------------------------------------------------- Year 3 $676 $637 - ----------------------------------------------------------------------------------- Year 5 $1,159 $1,093 - ----------------------------------------------------------------------------------- Year 10 $2,300 $2,137 - ----------------------------------------------------------------------------------- Class I Class Y - ----------------------------------------------------------------------------------- Year 1 $128 $81 - ----------------------------------------------------------------------------------- Year 3 $400 $252 - ----------------------------------------------------------------------------------- Year 5 $692 $439 - ----------------------------------------------------------------------------------- Year 10 $1,523 $978 - ----------------------------------------------------------------------------------- Reasons for the Proposed Reorganization The Trustees believe that the proposed Reorganization is in the best interests of Amsouth Select Equity Fund. The Trustees considered the following matters, among others, in approving the proposal. First, AAMI, the investment adviser to your AmSouth Fund, and AmSouth Bank informed the Trustees that they did not intend to continue to provide investment advisory services to the AmSouth Funds. Consequently, a change in your Fund's investment adviser was necessary. In the absence of the Reorganization, such a change would be more likely to motivate shareholders invested in reliance on AAMI's role to withdraw from the Fund, thereby reducing fund size and increasing fund expense ratios. Second, the resources of Pioneer. At December 31, 2004, Pioneer managed over 80 investment companies and accounts with approximately $42 billion in assets. Pioneer is part of the global asset management group of UniCredito Italiano S.p.A., one of the largest banking groups in Italy, providing investment management and financial services to mutual funds, institutional and other clients. As of December 31, 2004, assets under management of UniCredito Italiano S.p.A. were approximately $175 billion worldwide. Shareholders of your AmSouth Fund would become part of a significantly larger family of funds that offers a more diverse array of investment options and enhanced shareholder account options. The Pioneer 13 family of mutual funds offers over 80 funds, including domestic and international equity and fixed income funds and a money market fund that will be available to your AmSouth Fund's shareholders through exchanges. In addition, Pioneer offers shareholders additional options for their accounts, including the ability to transact and exchange shares over the telephone or online and the ability to access account values and transaction history in all of the shareholder's direct accounts in the Pioneer Funds over the telephone or online. Third, Pioneer Focused Equity Fund's management fee (0.65% of average daily net assets up to $1 billion, and 0.60% on assets greater than $1 billion) will be substantially lower than the advisory fee of your AmSouth Fund (0.80% of average daily net assets). The aggregate Rule 12b-1 distribution and shareholder servicing fees and non-Rule 12b-1 shareholder servicing fees paid by the Class A and Class B shares of both Funds will be the same. Moreover, your AmSouth Fund's Class I shares pay a non 12b-1 shareholder servicing fee that will not be paid by the Pioneer Fund's Class Y shares. On a pro forma basis, the estimated expense ratio of each class of shares of the Pioneer Fund is estimated to be lower than the expense ratio of the corresponding class of your AmSouth Fund. In addition, the broader distribution arrangements of the Pioneer Fund offer greater potential for further asset growth and reduced per share expenses. Fourth, the Class A, B and Y shares of Pioneer Focused Equity Fund received in the Reorganization will provide AmSouth Select Equity Fund shareholders with exposure to substantially the same investment product as they currently have. Fifth, the transaction is structured to qualify as a tax-free reorganization under Section 368(a) of the Internal Revenue Code of 1986 and therefore will not be treated as a taxable sale of your AmSouth shares. Pioneer and AmSouth Bank will pay all costs of preparing and printing the Funds' proxy statements and solicitation costs incurred by the Funds in connection with the Reorganization. AAMI will otherwise be responsible for all costs and expenses of the AmSouth Fund in connection with the Reorganizations. The Trustees also considered that Pioneer and AmSouth Bank will benefit from the Reorganization. See "Will Pioneer and AmSouth Bank Benefit from the Reorganizations." The Board of Trustees of the Pioneer Fund also considered that the Reorganization presents an excellent opportunity for the Pioneer Fund to acquire investment assets 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 the Pioneer Fund and its shareholders. CAPITALIZATION The following table sets forth the capitalization of each Fund as of May 31, 2005, and the pro forma combined Fund as of May 31, 2005. - -------------------------------------------------------------------------------------------------------------- Pioneer Focused Equity AmSouth Select Fund Equity Fund Pioneer Focused (Pro Forma) May 31, 2005 Equity Fund May 31, 2005 - -------------------------------------------------------------------------------------------------------------- Total Net Assets (in thousands) $128,657 N/A $128,657 - -------------------------------------------------------------------------------------------------------------- Class A shares ................................... $20,736 N/A $20,736 - -------------------------------------------------------------------------------------------------------------- Class B shares ................................... $17,590 N/A $17,590 - -------------------------------------------------------------------------------------------------------------- Class I/Y shares ................................. $90,331 N/A $90,331 - -------------------------------------------------------------------------------------------------------------- Net Asset Value Per Share N/A - -------------------------------------------------------------------------------------------------------------- Class A shares ................................... $14.14 N/A $14.14 - -------------------------------------------------------------------------------------------------------------- Class B shares ................................... $13.68 N/A $13.68 - -------------------------------------------------------------------------------------------------------------- Class I/Y shares ................................. $14.21 N/A $14.21 - -------------------------------------------------------------------------------------------------------------- Shares Outstanding - -------------------------------------------------------------------------------------------------------------- Class A shares ................................... 1,466,769 N/A 1,466,769 - -------------------------------------------------------------------------------------------------------------- Class B shares ................................... 1,285,404 N/A 1,285,404 - -------------------------------------------------------------------------------------------------------------- Class I/Y shares ................................. 6,358,281 N/A 6,358,281 - -------------------------------------------------------------------------------------------------------------- 14 It is impossible to predict how many shares of the Pioneer Fund will actually be received and distributed by your AmSouth Fund on the Reorganization date. The table should not be relied upon to determine the amount of the Pioneer Fund's shares that will actually be received and distributed. BOARD'S EVALUATION AND RECOMMENDATION For the reasons described above, the Trustees, including the Independent Trustees, approved the Reorganization. In particular, the Trustees determined that the Reorganization is in the best interests of your AmSouth Fund. Similarly, the Board of Trustees of the Pioneer Fund, including its Independent Trustees, approved the Reorganization. They also determined that the Reorganization is in the best interests of the Pioneer Fund. The Trustees recommend that the shareholders of your AmSouth Fund vote FOR the proposal to approve the Agreement and Plan of Reorganization. 15 AmSouth Balanced Fund and Pioneer Classic Balanced Fund PROPOSAL 1(i) Approval of Agreement and Plan of Reorganization 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-2, because it contains details that are not in the summary. Each Fund has an investment objective of obtaining capital growth and current income and, consequently, the Funds have similar investment policies and risks.

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. Investment strategies In managing the equity portion of the Fund, In selecting equity securities, Pioneer uses a the AAMI combines fundamental and quantitative value approach to select the Fund's analysis with risk management to identify investments.

In addition, the AAMI may evaluates a security's potential value, identify companies with a history of including the attractiveness of its market above-average growth or companies that are valuation, based on the company's assets and expected to enter periods of above-average prospects for earnings growth. In making that growth or are positioned in emerging growth assessment, Pioneer employs due diligence and industries. fundamental research, an evaluation of the issuer based on its financial statements and AAMI's fixed income portfolio management operations. Pioneer also considers a process focuses on the four key areas of security's potential to provide a reasonable duration management, sector weights, position amount of income. Pioneer relies on the on the yield curve, and security selection; knowledge, experience and judgment of its AAMI's goal is to add value in each of staff who have access to a wide variety of these four areas through the active management research. Pioneer focuses on the quality and of the Fund's portfolio. Beginning with price of individual issuers, not on economic rigorous fundamental analysis of the economy sector or market-timing strategies. Factors and taking into account characteristics of the Pioneer looks for in selecting investments current business and interest rate cycles, include: AAMI arrives at a projection of the likely trend in interest rates and adjusts duration o Favorable expected returns relative accordingly.

In assessing the appropriate maturity, rating and 3 AmSouth Balanced Fund Pioneer Classic Balanced Fund - ----------------------------------------------------------------------------------------------------------------------------- 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. Other investments The Fund may also invest in debt securities, Up to 10% of the Fund's total assets may be preferred stock and that portion of the value invested in debt securities rated below of securities convertible in to common stock, investment grade, including convertible debt. including convertible preferred stock and A debt security is investment grade if it is convertible debt, which is attributable to the rated in one of the top four categories by a fixed income characteristics of those nationally recognized statistical rating securities. 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. The Fund may invest up to 25% of its total assets in real estate investment trusts (REITs). REITs are companies that invest primarily in real estate or real estate related loans. The Fund may invest up to 25% of its total assets in equity and debt securities of non-U.S. issuers. The Fund will not invest more than 5% of its total assets in the securities of emerging markets issuers. The Fund invests in non-U.S. securities to diversify its portfolio when they offer similar or greater potential for capital appreciation. Temporary defensive When AAMI determines adverse market conditions Normally, Pioneer Classic Balanced Fund strategies exist, AmSouth Balanced Fund may invest invests substantially all of its assets to entirely in cash positions, directly in U.S. meet its investment objective. The Fund may Government securities and short-term paper, invest the remainder of its assets in such as bankers' acceptances. securities with remaining maturities of less than one year, cash equivalents or may hold cash. For temporary defensive purposes, including 4 AmSouth Balanced Fund Pioneer Classic Balanced Fund - ----------------------------------------------------------------------------------------------------------------------------- during periods of unusual cash flows, the 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, the Fund may not be able to achieve its investment objective. The 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. Diversification Each Fund is diversified for the purpose of the Investment Company Act and is subject to diversification requirements under the Internal Revenue Code of 1986, as amended (the "Code"). Industry concentration AmSouth Balanced Fund may not purchase any Pioneer Classic Balanced Fund may not invest securities which would cause more than 25% of more than 25% of its assets in any one the value of the Fund's total assets at the industry. time of purchase to be invested in securities of one or more issuers conducting their principal business activities in the same industry, provided that (a) there is no limitation with respect to obligations issued or guaranteed by the U.S. government or its agencies or instrumentalities, and repurchase agreements secured by obligations of the U.S. government or its agencies or instrumentalities; (b) wholly owned finance companies will be considered to be in the industries of their parents if their activities are primarily related to financing the activities of their parents; and (c) utilities will be divided according to their services. For example, gas, gas transmission, electric and gas, electric, and telephone will each be considered a separate industry.

Derivative instruments AmSouth Balanced Fund may invest in futures The Fund may use futures and options on contracts and options thereon (interest rate securities, indices and currencies, forward futures contracts or index futures contracts, foreign currency exchange contracts and other as applicable) to commit funds awaiting derivatives. A derivative is a security or investment, to maintain cash liquidity or for instrument whose value is determined by other hedging purposes.

If changes in a derivative's value do not correspond to 6 AmSouth Balanced Fund Pioneer Classic Balanced Fund - ----------------------------------------------------------------------------------------------------------------------------- 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. Short-term trading The AmSouth Fund may engage in the technique The Fund usually does not trade for short-term of short-term trading. Such trading involves profits. The Fund will sell an investment, the selling of securities held for a short however, even if it has only been held for a time, ranging from several months to less than short time, if it no longer meets the Fund's a day. The object of such short-term trading investment criteria. is to increase the potential for capital appreciation and/or income of the Fund in order to take advantage of what AAMI believes are changes in market, industry or individual company conditions or outlook. Other investment policies As described above, the Funds have substantially similar principal investment strategies and and restrictions policies. Certain of the non-principal investment policies and restrictions are different. For a more complete discussion of each Fund's other investment policies and fundamental and non-fundamental investment restrictions, see the SAI.

Comparison of Principal Risks of Investing in the Funds Because each Fund has a similar investment objective, primary investment policies and strategies, the Funds are subject to the same principal risks. You could lose money on your investment in either Fund or not make as much as if you invested elsewhere if: o The stock market goes down (this risk may be greater in the short term) o The adviser's judgment about the attractiveness, growth potential or potential appreciation of a particular stock proves to be incorrect o The market segment on which the Fund equity investment are focused - value and growth stocks - under performs other kinds of investments or market averages o The value of the Fund's fixed-income investments declines due to an increase in interest rates (generally, an increase in the average maturity of the fixed income portfolio of the Fund will make it more sensitive to interest rate risk) 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 An issuer cannot make timely interest and principal payments on its debt securities, such as bonds (the lower a security's rating, the greater its credit risk) 10 Each Fund may trade securities actively to achieve its principal investment strategies. Active trading of portfolio securities could increase each Fund's transaction costs (thereby lowering its performance) and may increase the amount of taxes that you pay (on distributions of net gains realized on those trades). If either Fund invests in securities with additional risk, that Fund's share price volatility accordingly could be greater and its performance lower. At times, more than 25% of the Fund's assets may be invested in the same market segment, such as financials or technology. To the extent the Fund emphasizes 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. If the 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. Pioneer Classic Balanced Fund may be subject to the following additional risks associated with investing in non-U.S. issuers, which 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 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 Past Performance Set forth below is performance information for AmSouth Balanced Fund. The bar charts show how AmSouth Balanced Fund's total return (not including any deduction for sales charges) has varied from year to year for each full calendar year. The tables show average annual total return for AmSouth Balanced Fund over time for each class of shares compared with a broad-based securities market index. The bar charts give an indication of the risks of investing in AmSouth Balanced Fund, including the fact that you could incur a loss and experience volatility of returns year to year.

Performance for the Class B shares, which were first offered on 9/2/97, is based on the historical performance of the Fund's Class A shares (without sales charge) prior to that date. The historical performance of the Class B shares has been restated to reflect the Fund's Class B shares distribution (12b-1) fees and the contingent deferred sales charge. (2) Performance for the Class I shares, which were first offered on 9/1/97, is based on the historical performance of the Fund's Class A shares (without sales charge) prior to that date. The table shows the impact of taxes on the Fund's returns. After-tax returns are only shown for Class A shares and may vary for Class B shares. The Fund's after-tax returns are calculated using the highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. In certain cases, the figure representing "Return After Taxes on Distributions and Sale of Fund Shares" may be higher than the other return figures for the same period. A higher after-tax return results when a capital loss occurs upon redemption and translates into an assumed tax deduction that benefits the shareholder. Please note that actual after-tax returns depend on an investor's tax situation and may differ from those shown. Also note that after-tax returns shown are not relevant to investors who hold their Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts. The most recent portfolio manager's discussion of AmSouth Balanced Fund's performance is attached as Exhibit C. 12 The Funds' Fees and Expenses Shareholders of both Funds pay various fees and expenses, either directly or indirectly. The table below shows the fees and expenses that you would pay if you were to buy and hold shares of each Fund. The expenses in the table appearing below are based on (i) for the AmSouth Balanced Fund, the expenses of AmSouth Balanced Fund for the period ended January 31, 2005 and (ii) for the Pioneer Classic Balanced Fund, the estimated pro forma annual expenses assuming the Reorganization occurred on May 31, 2005.

(2) Sales charges may be reduced depending upon the amount invested or, in certain circumstances, waived. Class A shares of the Pioneer Fund bought as part of an investment of $1 million or more are not subject to an initial sales charge, but may be charged a CDSC of 1.00% if sold within one year of purchase. 13 (3) A CDCS on Class B shares held continuously declines over six years starting with year one and ending in year seven from: 5%, 4%, 3%, 3%, 2%, 1%. Eight years after purchase Class B shares automatically convert to Class A shares. (4) To discourage short-term trading, a redemption fee of 2.00% will be charged on sales or exchanges of Class A, Class B and Class I shares of your AmSouth Fund made within 7 days of the date of purchase. A wire transfer fee of $7.00 will be deducted from the amount of your redemption if you request a wire transfer. (5) Other expenses for your AmSouth Fund are being limited to 0.53% for Class A shares, 0.53% for Class B shares and 0.38% for Class I shares. Any fee waiver or expense reimbursement arrangement is voluntary and may be discontinued at any time. (6) The Pioneer Fund's total annual operating expenses in the table have not been reduced by any expense offset arrangements. The hypothetical example below helps you compare the cost of investing in each Fund. It assumes that: (a) you invest $10,000 in each Fund for the time periods shown, (b) you reinvest all dividends and distributions, (c) your investment has a 5% return each year, (d) each Fund's gross operating expenses remain the same, and (e) the expense limitation for your Fund is in effect for year one. The examples are for comparison purposes only and are not a representation of either Fund's actual expenses or returns, either past or future.

The Trustees considered the following matters, among others, in approving the proposal. First, AAMI, the investment adviser to your AmSouth Fund, and AmSouth Bank informed the Trustees that they did not intend to continue to provide investment advisory services to the AmSouth Funds. Consequently, a change in your Fund's investment adviser was necessary. In the absence of the Reorganization, such a change would be more likely to motivate 14 shareholders invested in reliance on AAMI's role to withdraw from the Fund, thereby reducing fund size and increasing fund expense ratios. Second, the resources of Pioneer. At December 31, 2004, Pioneer managed over 80 investment companies and accounts with approximately $42 billion in assets. Pioneer is part of the global asset management group of UniCredito Italiano S.p.A., one of the largest banking groups in Italy, providing investment management and financial services to mutual funds, institutional and other clients. As December 31, 2004, assets under management of UniCredito Italiano S.p.A. were approximately $175 billion worldwide. Shareholders of your AmSouth Fund would become part of a significantly larger family of funds that offers a more diverse array of investment options and enhanced shareholder account options. The Pioneer family of mutual funds offers over 80 funds, including domestic and international equity and fixed income funds and a money market fund that will be available to your AmSouth Fund's shareholders through exchanges. In addition, Pioneer offers shareholders additional options for their accounts, including the ability to transact and exchange shares over the telephone or online and the ability to access account values and transaction history in all of the shareholder's direct accounts in the Pioneer Funds over the telephone or online. Third, Pioneer Classic Balanced Fund's management fee (0.65% of average daily net assets on the first $1 billion, 0.60% on the next $4 billion, and 0.55% on assets over $5 billion) will be substantially lower than the advisory fee of your Fund (0.80% of average daily net assets). The aggregate Rule 12b-1 distribution and shareholder servicing fees and non-Rule 12b-1 shareholder servicing fees paid by the Class A and Class B shares of both Funds will be the same. Moreover, your AmSouth Fund's Class I shares pay a non 12b-1 shareholder servicing fee that will not be paid by the Pioneer Fund's Class Y shares. On a pro forma basis, both the gross and net expenses of each class of the Pioneer Fund are estimated to be lower than the expenses of the corresponding class of your AmSouth Fund. In addition, the broader distribution arrangements of the Pioneer Fund offer greater potential for further asset growth and reduce per share expenses. Fourth, the Class A, B and Y shares of Pioneer Classic Balanced Fund received in the Reorganization will provide AmSouth Balanced Fund shareholders with exposure to substantially the same investment product as they currently have. Fifth, the transaction is structured to qualify as a tax-free reorganization under Section 368(a) of the Internal Revenue Code of 1986 and therefore will not be treated as a taxable sale of your AmSouth shares. Pioneer and AmSouth Bank will pay all costs of preparing and printing the Funds' proxy statements and solicitation costs incurred by the Funds in connection with the Reorganization. AAMI will otherwise be responsible for all costs and expenses of the AmSouth Fund in connection with the Reorganizations. The Trustees also considered that Pioneer and AmSouth Bank will benefit from the Reorganization. See "Will Pioneer and AmSouth Bank Benefit from the Reorganizations." The Board of Trustees of the Pioneer Fund also considered that the Reorganization presents an excellent opportunity for the Pioneer Fund to acquire investment assets 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 the Pioneer Fund and its shareholders. CAPITALIZATION The following table sets forth the capitalization of each Fund as of May 31, 2005, and the pro forma combined Fund as of May 31, 2005.

The table should not be relied upon to determine the amount of the Pioneer Fund's shares that will actually be received and distributed. BOARD'S EVALUATION AND RECOMMENDATION For the reasons described above, the Trustees, including the Independent Trustees, approved the Reorganization. In particular, the Trustees determined that the Reorganization is in the best interests of your AmSouth Fund. Similarly, the Board of Trustees of the Pioneer Fund, including its Independent Trustees, approved the Reorganization. They also determined that the Reorganization is in the best interests of the Pioneer Fund. The Trustees recommend that the shareholders of your AmSouth Fund vote FOR the proposal to approve the Agreement and Plan of Reorganization. 16 AmSouth Strategic Portfolios: Aggressive Growth Portfolio and Pioneer Ibbotson Aggressive Allocation Fund PROPOSAL 1(j) Approval of Agreement and Plan of Reorganization 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-1, because it contains details that are not in the summary. Each Fund is structured as a "fund of funds," which means all of its assets are invested in other mutual funds ("underlying funds"). Your Fund invests only in other AmSouth funds. Currently, the Pioneer Fund only invests in other Pioneer Funds but is seeking an exemptive order from the Securities and Exchange Commission that would permit the Pioneer Fund to invest, in addition, in mutual funds that are not managed by Pioneer. To the extent Pioneer receives an order from the Securities and Exchange Commission that permits Pioneer to invest in such other non-Pioneer underlying funds, Pioneer and the Pioneer Fund intend to rely on such order, subject to any applicable conditions of the order. In the table below, if a row extends across the entire table, the policy disclosed applies to both your AmSouth Fund and the Pioneer Fund.

Certain of the Pioneer Funds into which the AmSouth Funds are being reorganized are not currently included in the above list of funds underlying the Pioneer Fund. Pioneer and Ibbotson may determine to include such additional Pioneer Funds in the list of permitted investments for the Pioneer Fund into which your Fund is being reorganized. Alternatively, Pioneer and Ibbotson may determine to hold those additional Pioneer Funds temporarily until the Pioneer Fund's portfolio is rebalanced. Appendix A contains a summary description of each of the underlying Pioneer funds. 5 AmSouth Strategic Portfolios: Aggressive Pioneer Ibbotson Aggressive Allocation Growth Portfolio Fund - ------------------------------------------------------------------------------------------------------------------------------------ Normally, the Fund invests substantially all of its assets in underlying funds to meet its investment objective. However, the Fund may invest a portion of its assets in cash, cash equivalents or in money market funds. The underlying funds may also invest a portion of their assets in money market funds, 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, the Fund and each of the underlying funds 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, the Fund may not be able to achieve its investment objective. The Fund intends to adopt a defensive strategy when Pioneer or Ibbotson believes securities in which the Fund normally invests have extraordinary risks due to political or economic factors and in other extraordinary circumstances.

Class I shares may be exchanged for Class A shares of the same fund. No transaction fees are currently charged for exchanges. If you sell your shares or exchange them for shares of another AmSouth fund within 7 days of the date of purchase, you will be charged a 2.00% fee on the current net asset value of the shares sold or exchanged. The fee is paid to the Fund to offset the costs associated with short- term trading, such as portfolio transaction and administrative costs. The Fund uses a "first-in, first-out" method to determine how long you have held your shares. This means that if you purchased shares on different days, the shares purchased first will be considered redeemed first for purposes of determining whether the redemption fee will be charged. The fee will be charged on all covered redemptions and exchanges, including those made through retirement plan, brokerage and other types of omnibus accounts (except where it is not practical for the plan administrator or brokerage firm to implement the fee). The Fund will not impose the redemption fee on a redemption or exchange of shares purchased upon the reinvestment of dividend and capital gain distributions. Selling shares Shares of each Fund are sold at the net asset value per share next calculated after the Fund receives your request in good order. You may sell your shares by contacting the Normally, your investment firm will send Fund directly in writing or by telephone or by your request to sell shares to PIMSS.

If the account is established in the shareholder's own name, shareholders may also redeem shares of the Fund by telephone or online. Comparison of Principal Risks of Investing in the Funds Because each Fund has a similar investment objective, primary investment policies and strategies, the Funds are subject to the same principal risks. You could lose money on an investment in a Fund or a Fund may not perform as well as other investment options. Fund of funds structure and layering of fees 9 Each Fund is structured as a fund of funds. Each Fund's investments are focused in the underlying funds, so the Fund's investment performance is directly related to the performance of the underlying funds. Each Fund's net asset value will be affected by the performance of the equity and bond markets and the value of the mutual funds in which the Fund invests. Since the Funds mainly invest in the underlying funds, as opposed to other types of securities, the Funds do not have the same flexibility in their portfolio holdings as many mutual funds. In addition, each Fund indirectly pays a portion of the expenses incurred by the underlying funds. Consequently, an investment in a Fund entails more direct and indirect expenses than a direct investment in the underlying funds. For instance, you will pay management fees and operating expenses of both the Fund and the underlying funds. The underlying funds will not necessarily make consistent investment decisions, which may also increase your costs. One underlying fund may buy the same security that another underlying fund is selling. You would indirectly bear the costs of both trades without achieving any investment purpose. These transactions may also generate taxable gains. You may receive taxable gains from portfolio transactions by the underlying funds as well as taxable gains from the Fund's transactions in shares of the underlying funds. Currently, Pioneer manages all of the funds underlying the Pioneer Fund. Because the portfolio management teams of each of the underlying Pioneer funds may draw upon the resources of the same equity and fixed income analyst team or may share common investment management styles or approaches, the underlying funds may hold many common portfolio positions, reducing the diversification benefits of an asset allocation style. Equity investments Equity funds invest primarily in equity securities (such as stocks), which are more volatile and carry more risks than some other forms of investment. When the value of the stocks held by an underlying equity fund goes down, the value of your investment in the Fund will be affected. The underlying equity funds have risks associated with investing in equity securities. An equity fund could underperform other investments if: o The stock market goes down (this risk may be greater in the short term) o The fund's equity investments do not have the growth potential or value characteristics originally expected o Stocks selected for income do not achieve the same return as securities selected for capital growth o The types of stocks in which the fund invests or the fund's investment approach fall out of favor with investors Fixed income investments Fixed income funds primarily invest in debt securities, such as government securities, investment grade corporate securities, junk bonds, mortgaged backed securities, asset-backed securities, and money market securities. The value of your investment in the fund will change as the value of investments of the underlying funds increases and decreases. The underlying fixed income funds have risks associated with investing in debt securities. A 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 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 The investment manager's judgment about the attractiveness, relative value or potential appreciation of a particular sector, security or investment strategy proves to be incorrect Equity securities of smaller companies 10 Compared to large companies, small and mid-sized companies, and the market for their equity securities, are likely to: o Be more sensitive to changes in the economy, earnings results and investor expectations o Have more limited product lines and capital resources o Experience sharper swings in market values o Be harder to sell at the times and prices Pioneer thinks appropriate o Offer greater potential for loss than other U.S. equity securities Equity securities of real estate industry issuers Specific risks associated with the real estate industry include: o The U.S. or a local real estate market declines due to adverse economic conditions, overbuilding and high vacancy rates, reduced or regulated rents or other causes o Interest rates go up. Rising interest rates can adversely affect the availability and cost of financing for property acquisitions and other purposes and reduce the value of a REIT's fixed income investments o The values of properties owned by a REIT or the prospects of other real estate industry issuers may be hurt by property tax increases, zoning changes, other governmental actions, environmental liabilities, natural disasters or increased operating expenses o A REIT in an underlying fund's portfolio is, or is perceived by the market to be, poorly managed Non-U.S. securities Investing in non-U.S. issuers, including emerging market issuers, may involve unique risks compared to investing in securities of issuers in the U.S. These risks are more pronounced to the extent the fund invests in issuers in the lesser-developed emerging markets or in one region, such as Europe or the Pacific Rim. These risks may include: o Less information about the non-U.S. issuers or markets may be available due to less rigorous disclosure or accounting standards or regulatory practices 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 securities markets o Withholding and other non-U.S. taxes may decrease the fund's return High yield/below investment grade debt securities Investment in high yield securities involves substantial risk of loss. These securities are considered speculative with respect to the issuer's ability to pay interest and principal and are susceptible to default or decline in market value due to adverse economic and business developments. The market values for high yield securities tend to be very volatile, and these securities are less liquid than investment grade debt securities. For these reasons, your investment in the fund is subject to the following specific risks: o Increased price sensitivity to changing interest rates and deteriorating economic environment o Greater risk of loss due to default or declining credit quality o Adverse company specific events are more likely to render the issuer unable to make interest and/or principal payments o A negative perception of the high yield market develops, depressing the price and liquidity of high yield securities. This negative perception could last for a significant period of time Derivatives Certain underlying 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. The underlying funds may use derivatives for a variety of purposes, including: o As a hedge against adverse changes in stock market prices, 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 11 Even a small investment in derivatives can have a significant impact on a fund's exposure to stock market values, interest rates or currency exchange 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 table above shows the impact of taxes on AmSouth Strategic Portfolios: Aggressive Growth Portfolio's returns. After-tax returns are only shown for Class A shares and Class I shares and may vary for Class B shares. The Fund's after-tax returns are calculated using the highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. In certain cases, the figure representing "Return After Taxes on Distributions and Sale of Fund Shares" may be higher than the other return figures for the same period. A higher after-tax return results when a capital loss occurs upon redemption and translates into an assumed tax deduction that benefits the shareholder. Please note that actual after-tax returns depend on an investor's tax situation and may differ from those shown. Also note that 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.

(4) To discourage short-term trading, a redemption fee of 2.00% will be charged on sales or exchanges of Class A, Class B and Class I shares of your AmSouth Fund made within 7 days of the date of purchase. A wire transfer fee of $7.00 will be deducted from the amount of your redemption if you request a wire transfer. (5) Other expenses for your AmSouth Fund are being limited to 0.36% for Class A shares, 0.36% for Class B shares and 0.31% for Class I shares. Any fee waiver or expense reimbursement arrangement is voluntary and may be discontinued at any time. Pioneer has contractually agreed not to impose all or a portion of its fees or to limit other direct ordinary operating expenses to the extent required to reduce expenses, other than "Estimated average expense ratio of underlying funds," to 0.85% of the average daily net assets attributable to Class A shares and 1.64% of average daily net assets attributable to Class B shares. This expense limitation is in effect for Class A shares until December 1, 2008 and in effect for Class B until December 1, 2006. There can be no assurance that Pioneer will extend these expense limitations past such dates. The expense limitation does not limit the expenses of the underlying funds indirectly incurred by a shareholder. (6) The Pioneer Fund's total annual operating expenses in the table have not been reduced by any expense offset arrangements. (7) Class Y shares of the Pioneer Fund are being offered for the first time in connection with the Reorganization. 14 The hypothetical example below helps you compare the cost of investing in each Fund. It assumes that: (a) you invest $10,000 in each Fund for the time periods shown, (b) you reinvest all dividends and distributions, (c) your investment has a 5% return each year, and (d) each Fund's gross operating expenses remain the same. The examples are for comparison purposes only and are not a representation of either Fund's actual expenses or returns, either past or future. - ----------------------------------------------------------------------------------------------------- Number of years you AmSouth Strategic Portfolios: Pioneer Ibbotson Aggressive Combined Fund own your shares Aggressive Growth Portfolio Allocation Fund (Pro Forma) - ----------------------------------------------------------------------------------------------------- Class A - ----------------------------------------------------------------------------------------------------- Year 1 $ 758 $ 742 $ 742 - ----------------------------------------------------------------------------------------------------- Year 3 $1,192 $1,145 $1,091 - ----------------------------------------------------------------------------------------------------- Year 5 $1,650 N/A $1,515 - ----------------------------------------------------------------------------------------------------- Year 10 $2,916 N/A $2,691 - ----------------------------------------------------------------------------------------------------- Class B --- assuming redemption at end of period - ----------------------------------------------------------------------------------------------------- Year 1 $ 798 $ 666 $ 667 - ----------------------------------------------------------------------------------------------------- Year 3 $1,213 $1,172 $1,206 - ----------------------------------------------------------------------------------------------------- Year 5 $1,752 N/A $1,669 - ----------------------------------------------------------------------------------------------------- Year 10 $3,087 N/A $3,092 - ----------------------------------------------------------------------------------------------------- Class B --- assuming no redemption - ----------------------------------------------------------------------------------------------------- Year 1 $ 298 $ 266 $ 267 - ----------------------------------------------------------------------------------------------------- Year 3 $ 913 $ 872 $ 906 - ----------------------------------------------------------------------------------------------------- Year 5 $1,552 N/A $1,569 - ----------------------------------------------------------------------------------------------------- Year 10 $3,087 N/A $3,092 - ----------------------------------------------------------------------------------------------------- Class I Class Y - ----------------------------------------------------------------------------------------------------- Year 1 $ 211 N/A $ 160 - ----------------------------------------------------------------------------------------------------- Year 3 $ 652 N/A $ 496 - ----------------------------------------------------------------------------------------------------- Year 5 $1,119 N/A $ 855 - ----------------------------------------------------------------------------------------------------- Year 10 $2,410 N/A $1,867 - ----------------------------------------------------------------------------------------------------- Reasons for the Proposed Reorganization The Trustees believe that the proposed Reorganization is in the best interests of AmSouth Strategic Portfolios: Aggressive Growth Portfolio. The Trustees considered the following matters, among others, in approving the proposal. First, AAMI, the investment adviser to your AmSouth Fund, informed the Trustees that it does not intend to continue to provide investment advisory services to the AmSouth Funds. Consequently, a change in your Fund's investment adviser was necessary. In the absence of the Reorganization, such a change would be more likely to motivate shareholders invested in reliance on AAMI's role to withdraw from the Fund, thereby reducing fund size and increasing fund expense ratios. Second, the resources of Pioneer. At December 31, 2004, Pioneer managed over 80 investment companies and accounts with approximately $42 billion in assets, including $15.7 billion in fixed income securities. Pioneer is part of the global asset management group of UniCredito Italiano S.p.A., one of the largest banking groups in Italy, providing investment management and financial services to mutual funds, institutional and other clients. As of December 31, 2004, assets under management of UniCredito Italiano S.p.A. were approximately $175 billion worldwide. Shareholders of your AmSouth Fund would become part of a significantly larger family of funds that offers a more diverse array of investment options and enhanced shareholder account options. The Pioneer family of mutual funds offers over 80 funds, including domestic and international equity and fixed income funds and a money market fund that will be available to your AmSouth Fund's shareholders through exchanges. Third, Pioneer Ibbotson Aggressive Allocation Fund's management fee (0.17% of average daily net assets) is lower than the advisory fee of your Fund (0.20% of average daily net assets). Both the historical and estimated pro forma expenses of the Pioneer Fund, after giving effect to the Reorganization, on a gross and net basis are lower than your Fund's gross and net operating expenses. The aggregate Rule 12b-1 distribution and shareholder servicing fees and non-Rule 12b-1 shareholder 15 servicing fees paid by both the Class A and Class B shares of Funds are the same. Moreover, your AmSouth Fund's Class I shares pay a non 12b-1 shareholder servicing fee that is not paid by the Pioneer Fund's Class Y shares. In addition, the broader distribution arrangements of the Pioneer Fund offer greater potential for further asset growth and reduce per share expenses. Fourth, because of Pioneer distribution arrangements, Pioneer Fund has greater potential to further increase the assets compared to your Fund. Further assets growth is anticipated to further reduce the combined Fund's gross operating expenses per share. Fifth, the Class A, B and Y shares of the Pioneer Fund received in the Reorganization will provide AmSouth Fund shareholders with exposure to a similar investment product as they currently have. The Trustees also noted that the allocation decisions are made by Ibbotson, a leading asset allocation adviser, and that the Pioneer Fund intends, as soon as permitted by the SEC, to include unaffiliated mutual funds as underlying funds. Sixth, The transaction is structured to qualify as a tax-free reorganization under Section 368(a) of the Internal Revenue Code of 1986 and therefore will not be treated as a taxable sale of your AmSouth shares. Pioneer and AmSouth Bank will pay all costs of preparing and printing the Funds' proxy statements and solicitation costs incurred by the Funds in connection with the Reorganization. AAMI will otherwise be responsible for all costs and expenses of AmSouth Fund in connection with the Reorganization. The Trustees also considered that Pioneer and AmSouth Bank will benefit from the Reorganization. See "Will Pioneer and AmSouth Bank Benefit from the Reorganizations." The Board of Trustees of the Pioneer Fund also considered that the Reorganization presents an excellent opportunity for the Pioneer Fund to acquire investment assets 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 the Pioneer Fund and its shareholders. CAPITALIZATION The following table sets forth the capitalization of each Fund as of May 31, 2005, and the pro forma combined Fund as of May 31, 2005. AmSouth Strategic Pioneer Ibbotson Portfolios: Pioneer Ibbotson Aggressive Aggressive Growth Aggressive Allocation Fund Portfolio Fund Allocation Fund (Pro Forma) May 31, 2005 May 31, 2005 May 31, 2005 - -------------------------------------------------------- ------------------ ----------------- ---------------- Total Net Assets (in thousands) $ 53,136 $ 24,987 $ 78,123 Class A shares ................................... $ 22,953 $ 14,975 $ 37,928 Class B shares ................................... $ 15,156 $ 4,269 $ 19,425 Class I/Y shares ................................. $ 15,028 N/A $ 15,028 Net Asset Value Per Share Class A shares ................................... $ 9.60 $ 11.21 $ 11.21 Class B shares ................................... $ 9.19 $ 10.82 $ 10.82 Class I shares ................................... $ 9.60 N/A $ 11.21 Shares Outstanding Class A shares ................................... 2,391,779 1,335,779 3,383,164 Class B shares ................................... 1,649,291 394,722 1,795,948 Class I/Y shares ................................. 1,565,894 N/A 1,340,485 It is impossible to predict how many shares of the Pioneer Fund will actually be received and distributed by your AmSouth Fund on the Reorganization date. The table should not be relied upon to determine the amount of the Pioneer Fund's shares that will actually be received and distributed. 16 BOARD'S EVALUATION AND RECOMMENDATION For the reasons described above, the Trustees, including the Independent Trustees, approved the Reorganization. In particular, the Trustees determined that the Reorganization is in the best interests of your AmSouth Fund. Similarly, the Board of Trustees of the Pioneer Fund, including its Independent Trustees, approved the Reorganization. They also determined that the Reorganization is in the best interests of the Pioneer Fund. The Trustees recommend that the shareholders of your AmSouth Fund vote FOR the proposal to approve the Agreement and Plan of Reorganization. 17 Appendix A Information about the underlying funds The following is intended to summarize the investment objectives and primary strategies of, and to provide you with certain other information about, the underlying funds. These summaries do not reflect all of the investment policies and strategies that are disclosed in each underlying fund's prospectus, and are not an offer of the underlying funds' shares. The underlying funds in which the funds intend to invest may change from time to time and the funds may invest in underlying funds in addition to those described below at the discretion of Pioneer without prior notice to or approval of shareholders. The prospectus and SAI for each underlying fund is available on the SEC's website as well as on our website at www.pioneerfunds.com. Each underlying fund normally will be invested according to its investment strategy. However, an underlying fund also may have the ability to invest without limitation in money market instruments or other investments for temporary, defensive purposes. The underlying funds that invest primarily in equity securities are: Pioneer Fund Investment objective Reasonable income and capital growth. Principal investment strategies The fund invests in a broad list of carefully selected, reasonably priced securities rather than in securities whose prices reflect a premium resulting from their current market popularity. The fund invests the major portion of its assets in equity securities, primarily of U.S. issuers. For purposes of the fund's investment policies, equity securities include common stocks, convertible debt and other equity instruments, such as depositary receipts, warrants, rights and preferred stocks. Investment Adviser Pioneer Pioneer Research Fund Investment objective Long-term capital growth. Principal investment strategies Normally, the fund invests at least 80% of its assets in equity securities, primarily of U.S. issuers.

Principal investment strategies Normally, the fund invests at least 80% of its net assets (plus the amount of borrowings, if any, for investment purposes) in equity securities of U.S. issuers. The fund invests primarily in securities, traded in the U.S., of issuers that the subadviser believes have substantial international activities. In evaluating whether an issuer has substantial international activities, the subadviser considers the degree to which the issuer has non-U.S. reported sales and revenues, operating earnings or tangible assets. The fund may invest up to 20% of the value of its investments in equity securities of non-U.S. issuers that are traded in U.S. markets. Investment Adviser Pioneer (adviser); L. Roy Papp & Associates, LLP (subadviser) Pioneer Oak Ridge Large Cap Growth Fund Investment objective Capital appreciation. Principal investment strategies Normally, the fund invests at least 80% of its net assets (plus the amount of borrowings, if any, for investment purposes) in equity securities of large capitalization U.S. companies. Large capitalization companies have market capitalizations at the time of acquisition of $3 billion or more. The fund anticipates that the average weighted market capitalization of the companies in the fund's portfolio will be significantly higher that $3 billion. The equity securities in which the fund principally invests are common stocks, preferred stocks, depositary receipts and convertible debt, but the fund may invest in other types of equity securities to a lesser extent, such as warrants and rights.

The Russell 2000 Index measures the performance of the 2,000 smallest companies in the Russell 3000 Index. The size of the companies in the index changes with market conditions and the composition of the index.

Investment Adviser Pioneer Pioneer International Value Fund Investment objective Long-term capital growth. Principal investment strategies Normally, the fund invests at least 80% of its total assets in equity securities of non-U.S. issuers. These issuers may be located in both developed and emerging markets. Under normal circumstances, the fund's assets will be invested in securities of companies domiciled in at least three different foreign countries. Generally, the fund's investments in any country are limited to 25% or less of its total assets. However, the fund may invest more than 25% of its assets in issuers organized in Japan or the United Kingdom or in securities quoted or denominated in the Japanese yen, the British pound and the euro. Investment of a substantial portion of the fund's assets in such countries or currencies will subject the fund to the risks of adverse securities markets, exchange rates and social, political or economic events which may occur in those countries. The fund may invest without limitation in securities of issuers located in countries with emerging economies or securities markets, but will not invest more than 25% of its total assets in securities of issuers located in any one such country. For purposes of the fund's investment policies, equity securities include common stocks, convertible debt and other equity instruments, such as depositary receipts, warrants, rights and preferred shares.

Investment Adviser Pioneer (adviser); AEW Management and Advisors, L.P. (subadviser) The underlying funds that invest primarily in debt securities are: Pioneer Bond Fund Investment objective To provide current income from an investment grade portfolio with due regard to preservation of capital and prudent investment risk. The fund also seeks a relatively stable level of dividends; however, the level of dividends will be maintained only if consistent with preserving the investment grade quality of the fund's portfolio. Principal investment strategies The fund invests primarily in: o Debt securities issued or guaranteed by the U.S. government or its agencies and instrumentalities, o Debt securities, including convertible debt, of corporate and other issuers rated at least investment grade at the time of investment, and comparably rated commercial paper, 24 o Cash and cash equivalents, certificates of deposit, repurchase agreements maturing in one week or less and bankers' acceptances. Normally, the fund invests at least 80% of its total assets in these securities. In addition, the fund may invest up to 20% of its total assets in debt securities rated below investment grade or, if unrated, of equivalent quality as determined by Pioneer. Cash and cash equivalents include cash balances, accrued interest and receivables for items such as the proceeds, not yet received, from the sale of the fund's portfolio investments. Investment Adviser Pioneer Pioneer High Yield Fund Investment objective Maximize total return through a combination of income and capital appreciation. Principal investment strategies Normally, the fund invests at least 80% of its total assets in below investment grade (high yield) debt securities and preferred stocks. These high yield securities may be convertible into the equity securities of the issuer. 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 rated debt securities. Investment Adviser Pioneer Pioneer Short Term Income Fund Investment objective A high level of current income to the extent consistent with a relatively high level of stability of principal. Principal investment strategies The fund invests primarily in: o Debt securities issued or guaranteed by the U.S. government, its agencies or instrumentalities o Debt securities, including convertible debt, of corporate and other issuers and commercial paper o Mortgage-backed and asset-backed securities o Short-term money market instruments Normally, at least 80% of the fund's net assets are invested in debt securities that are rated investment grade at the time of purchase or cash and cash equivalents. Cash and cash equivalents may include cash balances, accrued interest and receivables for items such as the proceeds, not yet received, from the sale of the fund's portfolio investments. Investment Adviser Pioneer 25 Pioneer Cash Reserves Fund Investment objective High current income, preservation of capital and liquidity through investments in high-quality short-term securities. Principal investment strategies The fund seeks to maintain a constant net asset value of $1.00 per share by investing in high-quality, U.S. dollar denominated money market securities, including those issued by: o U.S. and foreign banks o U.S. and foreign corporate issuers o The U.S. government and its agencies and instrumentalities o Foreign governments o Multinational organizations such as the World Bank The fund may invest more than 25% of its total assets in U.S. government securities and obligations of U.S. banks. The fund may invest in any money market instrument that is a permissible investment for a money market fund under the rules of the Securities and Exchange Commission, including commercial paper, certificates of deposit, time deposits, bankers' acceptances, mortgage-backed and asset-backed securities, repurchase agreements, municipal obligations and other short-term debt securities. Investment Adviser Pioneer Pioneer Strategic Income Fund Investment objective A high level of current income. Principal investment strategies Normally, the fund invests at least 80% of its net assets (plus the amount of borrowings, if any, for investment purposes) in debt securities. The fund has the flexibility to invest in a broad range of issuers and segments of the debt securities markets. Pioneer Investment Management, Inc., the fund's investment adviser, allocates the fund's investments among the following three segments of the debt markets: o Below investment grade (high yield) securities of U.S. and non-U.S. issuers o Investment grade securities of U.S. issuers o Investment grade securities of non-U.S. issuers Pioneer's allocations among these segments of the debt markets depend upon its outlook for economic, interest rate and political trends. The fund invests primarily in: o Debt securities issued or guaranteed by the U.S. government, its agencies or instrumentalities or non-U.S. governmental entities 26 o Debt securities of U.S. and non-U.S. corporate issuers, including convertible debt o Mortgage-backed and asset-backed securities The fund's investments 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. The fund invests in securities with a broad range of maturities. Depending upon Pioneer's allocation among market segments, up to 70% of the fund's total assets may be in debt securities rated below investment grade at the time of purchase or determined to be of equivalent quality by Pioneer. Up to 20% of the fund's total assets may be invested in debt securities rated below CCC by Standard & Poor's Ratings Group or the equivalent by another 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 rated debt securities. As with all fixed income securities, the market values of convertible debt securities tend to decline as interest rates increase and, conversely, to increase as interest rates decline. However, when the market price of the common stock underlying a convertible security exceeds the conversion price, the convertible security tends to reflect the market price of the underlying common stock. Depending upon Pioneer's allocation among market segments, up to 85% of the fund's total assets may be in debt securities of non-U.S. corporate and governmental issuers, including debt securities of corporate and governmental issuers in emerging markets. Investment Adviser Pioneer 27 AmSouth Strategic Portfolios: Growth Portfolio and Pioneer Ibbotson Growth Allocation Fund PROPOSAL 1(k) Approval of Agreement and Plan of Reorganization 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-1, because it contains details that are not in the summary. Each Fund is structured as a "fund of funds," which means all of its assets are invested in other mutual funds ("underlying funds"). Your Fund invests only in other AmSouth funds. Currently, the Pioneer Fund only invests in other Pioneer Funds but is seeking an exemptive order from the Securities and Exchange Commission that would permit the Pioneer Fund to invest, in addition, in mutual funds that are not managed by Pioneer. To the extent Pioneer receives an order from the Securities and Exchange Commission that permits Pioneer to invest in such other non-Pioneer underlying funds, Pioneer and the Pioneer Fund intend to rely on such order, subject to any applicable conditions of the order. In the table below, if a row extends across the entire table, the policy disclosed applies to both your AmSouth Fund and the Pioneer Fund.

Certain of the Pioneer Funds into which the AmSouth Funds are being reorganized are not currently included in the above list of funds underlying the Pioneer Fund. Pioneer and Ibbotson may determine to include such additional Pioneer Funds in the list of permitted investments for the Pioneer Fund into which your Fund is being reorganized. Alternatively, Pioneer and Ibbotson may determine to hold those additional Pioneer Funds temporarily until the Pioneer Fund's portfolio is rebalanced. Appendix A contains a summary description of each of the underlying Pioneer funds. 5 AmSouth Strategic Portfolios: Growth Portfolio Pioneer Ibbotson Growth Allocation Fund - ----------------------------------------------------------------------------------------------------------------------------- Normally, the Fund invests substantially all of its assets in underlying funds to meet its investment objective. However, the Fund may invest a portion of its assets in cash, cash equivalents or in money market funds. The underlying funds may also invest a portion of their assets in money market funds, 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, the Fund and each of the underlying funds 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, the Fund may not be able to achieve its investment objective. The Fund intends to adopt a defensive strategy when Pioneer or Ibbotson believes securities in which the Fund normally invests have extraordinary risks due to political or economic factors and in other extraordinary circumstances.

AmSouth fund if you become eligible to purchase Class I shares. 8 AmSouth Strategic Portfolios: Growth Portfolio Pioneer Ibbotson Growth Allocation Fund - ---------------------------------------------------------------------------------------------------------------------------- Class I shares may be exchanged for Class A shares of the same fund. No transaction fees are currently charged for exchanges. If you sell your shares or exchange them for shares of another AmSouth fund within 7 days of the date of purchase, you will be charged a 2.00% fee on the current net asset value of the shares sold or exchanged. The fee is paid to the Fund to offset the costs associated with short-term trading, such as portfolio transaction and administrative costs. The Fund uses a "first-in, first-out" method to determine how long you have held your shares. This means that if you purchased shares on different days, the shares purchased first will be considered redeemed first for purposes of determining whether the redemption fee will be charged. The fee will be charged on all covered redemptions and exchanges, including those made through retirement plan, brokerage and other types of omnibus accounts (except where it is not practical for the plan administrator or brokerage firm to implement the fee). The Fund will not impose the redemption fee on a redemption or exchange of shares purchased upon the reinvestment of dividend and capital gain distributions. Selling shares Shares of each Fund are sold at the net asset value per share next calculated after the Fund receives your request in good order. You may sell your shares by contacting the Normally, your investment firm will send your Fund directly in writing or by telephone or by request to sell shares to PIMSS.

If the account is established in the shareholder's own name, shareholders may also redeem shares of the Fund by telephone or online. Comparison of Principal Risks of Investing in the Funds Because each Fund has a similar investment objective, primary investment policies and strategies, the Funds are subject to the same principal risks. You could lose money on an investment in a fund or a fund may not perform as well as other investment options. Fund of funds structure and layering of fees 9 Each Fund is structured as a fund of funds. Each Fund's investments are focused in the underlying funds, so the Fund's investment performance is directly related to the performance of the underlying funds. Each Fund's net asset value will be affected by the performance of the equity and bond markets and the value of the mutual funds in which the Fund invests. Since the Funds mainly invest in the underlying funds, as opposed to other types of securities, the Funds do not have the same flexibility in their portfolio holdings as many mutual funds. In addition, each Fund indirectly pays a portion of the expenses incurred by the underlying funds. Consequently, an investment in a Fund entails more direct and indirect expenses than a direct investment in the underlying funds. For instance, you will pay management fees and operating expenses of both the Fund and the underlying funds. The underlying funds will not necessarily make consistent investment decisions, which may also increase your costs. One underlying fund may buy the same security that another underlying fund is selling. You would indirectly bear the costs of both trades without achieving any investment purpose. These transactions may also generate taxable gains. You may receive taxable gains from portfolio transactions by the underlying funds as well as taxable gains from the fund's transactions in shares of the underlying funds. Currently, Pioneer manages all of the funds underlying the Pioneer Fund. Because the portfolio management teams of each of the underlying Pioneer funds may draw upon the resources of the same equity and fixed income analyst team or may share common investment management styles or approaches, the underlying funds may hold many common portfolio positions, reducing the diversification benefits of an asset allocation style. Equity investments Equity funds invest primarily in equity securities (such as stocks), which are more volatile and carry more risks than some other forms of investment. When the value of the stocks held by an underlying equity fund goes down, the value of your investment in the fund will be affected. The underlying equity funds have risks associated with investing in equity securities. An equity fund could underperform other investments if: o The stock market goes down (this risk may be greater in the short term) o The fund's equity investments do not have the growth potential or value characteristics originally expected o Stocks selected for income do not achieve the same return as securities selected for capital growth o The types of stocks in which the fund invests or the fund's investment approach fall out of favor with investors Fixed income investments Fixed income funds primarily invest in debt securities, such as government securities, investment grade corporate securities, junk bonds, mortgaged backed securities, asset-backed securities, and money market securities. The value of your investment in the fund will change as the value of investments of the underlying funds increases and decreases. The underlying fixed income funds have risks associated with investing in debt securities. A 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 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 The investment manager's judgment about the attractiveness, relative value or potential appreciation of a particular sector, security or investment strategy proves to be incorrect Equity securities of smaller companies Compared to large companies, small and mid-sized companies, and the market for their equity securities, are likely to: 10 o Be more sensitive to changes in the economy, earnings results and investor expectations o Have more limited product lines and capital resources o Experience sharper swings in market values o Be harder to sell at the times and prices Pioneer thinks appropriate o Offer greater potential for loss than other U.S. equity securities Equity securities of real estate industry issuers Specific risks associated with the real estate industry include: o The U.S. or a local real estate market declines due to adverse economic conditions, overbuilding and high vacancy rates, reduced or regulated rents or other causes o Interest rates go up. Rising interest rates can adversely affect the availability and cost of financing for property acquisitions and other purposes and reduce the value of a REIT's fixed income investments o The values of properties owned by a REIT or the prospects of other real estate industry issuers may be hurt by property tax increases, zoning changes, other governmental actions, environmental liabilities, natural disasters or increased operating expenses o A REIT in an underlying fund's portfolio is, or is perceived by the market to be, poorly managed Non-U.S. securities Investing in non-U.S. issuers, including emerging market issuers, may involve unique risks compared to investing in securities of issuers in the U.S. These risks are more pronounced to the extent the fund invests in issuers in the lesser-developed emerging markets or in one region, such as Europe or the Pacific Rim. These risks may include: o Less information about the non-U.S. issuers or markets may be available due to less rigorous disclosure or accounting standards or regulatory practices 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 securities markets o Withholding and other non-U.S. taxes may decrease the Fund's return High yield/below investment grade debt securities Investment in high yield securities involves substantial risk of loss. These securities are considered speculative with respect to the issuer's ability to pay interest and principal and are susceptible to default or decline in market value due to adverse economic and business developments. The market values for high yield securities tend to be very volatile, and these securities are less liquid than investment grade debt securities. For these reasons, your investment in the fund is subject to the following specific risks: o Increased price sensitivity to changing interest rates and deteriorating economic environment o Greater risk of loss due to default or declining credit quality o Adverse company specific events are more likely to render the issuer unable to make interest and/or principal payments o A negative perception of the high yield market develops, depressing the price and liquidity of high yield securities. This negative perception could last for a significant period of time Derivatives Certain underlying 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. The underlying funds may use derivatives for a variety of purposes, including: o As a hedge against adverse changes in stock market prices, 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 a fund's exposure to stock market values, interest rates or currency exchange rates. If changes in a derivative's value do not correspond to changes in the value of the 11 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 table above shows the impact of taxes on AmSouth Strategic Portfolios: Growth Portfolio's returns. After-tax returns are only shown for Class A shares and Class I shares and may vary for Class B shares. The Fund's after-tax returns are calculated using the highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. In certain cases, the figure representing "Return After Taxes on Distributions and Sale of Fund Shares" may be higher than the other return figures for the same period. A higher after-tax return results when a capital loss occurs upon redemption and translates into an assumed tax deduction that benefits the shareholder. Please note that actual after-tax returns depend on an investor's tax situation and may differ from those shown. Also note that 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. The Funds' Fees and Expenses Shareholders of both Funds pay various fees and expenses, either directly or indirectly.

(2) Sales charges may be reduced depending upon the amount invested or, in certain circumstances, waived. Class A shares of the Pioneer Fund bought as part of an investment of $1 million or more are not subject to an initial sales charge, but may be charged a CDSC of 1.00% if sold within one year of purchase. (3) For Class B shares purchased prior to the combination of AmSouth Funds with ISG Funds, the CDSC on such Class B shares held continuously declines over six years, starting with year one and ending in year seven from: 4%, 3%, 3%, 2%, 2%, 1%. For all other Class B shares held continuously, the CDSC declines over six years, starting with year one and ending in year seven from: 5%, 4%, 3%, 3%, 2%, 1%. Eight years after purchase (seven years in the case of shares acquired in the ISG combination), Class B shares automatically convert to Class A shares. (4) To discourage short-term trading, a redemption fee of 2.00% will be charged on sales or exchanges of Class A, Class B and Class I shares of your AmSouth Fund made within 7 days of the date of purchase. A wire transfer fee of $7.00 will be deducted from the amount of your redemption if you request a wire transfer. (5) Other expenses for your AmSouth Fund are being limited to 0.31% for Class A shares, 0.30% for Class B shares and 0.26% for Class I shares. Any fee waiver or expense reimbursement arrangement is voluntary and may be discontinued at any time. Pioneer has contractually agreed not to impose all or a portion of its fees or to limit other direct ordinary operating expenses to the extent required to reduce expenses, other than "Estimated average expense ratio of underlying funds," to 0.79% of the average daily net assets attributable to Class A shares and 1.57% of average daily net assets attributable to Class B shares. This expense limitation is in effect for Class A shares until December 1, 2008 and in effect for Class B until December 1, 2006. There can be no assurance that Pioneer will 14 extend these expense limitations past such dates. The expense limitation does not limit the expenses of the underlying funds indirectly incurred by a shareholder. (6) The Pioneer Fund's total annual operating expenses in the table have not been reduced by any expense offset arrangements. (7) Class Y shares of the Pioneer Fund are being offered for the first time in connection with the Reorganization. The hypothetical example below helps you compare the cost of investing in each Fund. It assumes that: (a) you invest $10,000 in each Fund for the time periods shown, (b) you reinvest all dividends and distributions, (c) your investment has a 5% return each year, and (d) each Fund's gross operating expenses remain the same. The examples are for comparison purposes only and are not a representation of either Fund's actual expenses or returns, either past or future.

The Trustees considered the following matters, among others, in approving the proposal. First, AAMI, the investment adviser to your AmSouth Fund, informed the Trustees that it does not intend to continue to provide investment advisory services to the AmSouth Funds. Consequently, a change in your Fund's investment adviser was necessary. In the absence of the Reorganization, such a change would be more likely to motivate shareholders invested in reliance on AAMI's role to withdraw from the Fund, thereby reducing fund size and increasing fund expense ratios. Second, the resources of Pioneer. At December 31, 2004, Pioneer managed over 80 investment companies and accounts with approximately $42 billion in assets, including $15.7 billion in fixed income securities. Pioneer is part of the global asset management group of UniCredito Italiano S.p.A., one of the largest banking groups in Italy, providing investment management and financial services to mutual funds, institutional and other clients. As of December 31, 2004, assets under management of UniCredito Italiano S.p.A. were approximately $175 billion worldwide. Shareholders of your AmSouth Fund would become part of a significantly larger family of funds that offers a more diverse array of investment options and enhanced shareholder account options. The Pioneer family of mutual funds offers over 80 funds, including domestic and international 15 equity and fixed income funds and a money market fund that will be available to your AmSouth Fund's shareholders through exchanges. Third, Pioneer Ibbotson Growth Allocation Fund's management fee (0.17% of average daily net assets) is lower than the advisory fee of your Fund (0.20% of average daily net assets). Both the historical and estimated pro forma expenses of the Pioneer Fund, after giving effect to the Reorganization, on a gross and net basis are lower than your Fund's gross and net operating expenses. The aggregate Rule 12b-1 distribution and shareholder servicing fees and non-Rule 12b-1 shareholder servicing fees paid by the Class A and Class B shares of both Funds are the same. Moreover, your AmSouth Fund's Class I shares pay a non 12b-1 shareholder servicing fee that is not paid by the Pioneer Fund's Class Y shares. Fourth, because of Pioneer distribution arrangements, Pioneer Fund has greater potential to further increase the assets compared to your fund. Further assets growth is anticipated to further reduce the combined Fund's gross operating expenses per share. Fifth, the Class A, B and Y shares of the Pioneer Fund received in the Reorganization will provide AmSouth Fund shareholders with exposure to a similar investment product as they currently have. The Trustees also noted that the allocation decisions are made by Ibbotson, a leading asset allocation adviser, and that the Pioneer Fund intends, as soon as permitted by the SEC, to include unaffiliated mutual funds as underlying funds. Sixth, the transaction is structured to qualify as a tax-free reorganization under Section 368(a) of the Internal Revenue Code of 1986 and therefore will not be treated as a taxable sale of your AmSouth shares. Pioneer and AmSouth Bank will pay all costs of preparing and printing the Funds' proxy statements and solicitation costs incurred by the Funds in connection with the Reorganization. AAMI will otherwise be responsible for all costs and expenses of AmSouth Fund in connection with the Reorganization. The Trustees also considered that Pioneer and AmSouth Bank will benefit from the Reorganization. See "Will Pioneer and AmSouth Bank Benefit from the Reorganizations." The Board of Trustees of the Pioneer Fund also considered that the Reorganization presents an excellent opportunity for the Pioneer Fund to acquire investment assets 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 the Pioneer Fund and its shareholders.

The table should not be relied upon to determine the amount of the Pioneer Fund's shares that will actually be received and distributed. BOARD'S EVALUATION AND RECOMMENDATION For the reasons described above, the Trustees, including the Independent Trustees, approved the Reorganization. In particular, the Trustees determined that the Reorganization is in the best interests of your AmSouth Fund. Similarly, the Board of Trustees of the Pioneer Fund, including its Independent Trustees, approved the Reorganization. They also determined that the Reorganization is in the best interests of the Pioneer Fund. The Trustees recommend that the shareholders of your AmSouth Fund vote FOR the proposal to approve the Agreement and Plan of Reorganization. 17 Appendix A Information about the underlying funds The following is intended to summarize the investment objectives and primary strategies of, and to provide you with certain other information about, the underlying funds. These summaries do not reflect all of the investment policies and strategies that are disclosed in each underlying fund's prospectus, and are not an offer of the underlying funds' shares. The underlying funds in which the funds intend to invest may change from time to time and the funds may invest in underlying funds in addition to those described below at the discretion of Pioneer without prior notice to or approval of shareholders. The prospectus and SAI for each underlying fund is available on the SEC's website as well as on our website at www.pioneerfunds.com. Each underlying fund normally will be invested according to its investment strategy. However, an underlying fund also may have the ability to invest without limitation in money market instruments or other investments for temporary, defensive purposes. The underlying funds that invest primarily in equity securities are: Pioneer Fund Investment objective Reasonable income and capital growth. Principal investment strategies The fund invests in a broad list of carefully selected, reasonably priced securities rather than in securities whose prices reflect a premium resulting from their current market popularity.

Principal investment strategies Normally, the fund invests at least 80% of its net assets (plus the amount of borrowings, if any, for investment purposes) in equity securities of U.S. issuers. The fund invests primarily in securities, traded in the U.S., of issuers that the subadviser believes have substantial international activities. In evaluating whether an issuer has substantial international activities, the subadviser considers the degree to which the issuer has non-U.S. reported sales and revenues, operating earnings or tangible assets. The fund may invest up to 20% of the value of its investments in equity securities of non-U.S. issuers that are traded in U.S. markets. Investment Adviser Pioneer (adviser); L. Roy Papp & Associates, LLP (subadviser) Pioneer Oak Ridge Large Cap Growth Fund Investment objective Capital appreciation. Principal investment strategies Normally, the fund invests at least 80% of its net assets (plus the amount of borrowings, if any, for investment purposes) in equity securities of large capitalization U.S. companies. Large capitalization companies have market capitalizations at the time of acquisition of $3 billion or more.

The Russell 2000 Index measures the performance of the 2,000 smallest companies in the Russell 3000 Index. The size of the companies in the index changes with market conditions and the composition of the index.

Under normal circumstances, the fund's assets will be invested in securities of companies domiciled in at least three different foreign countries. Generally, the fund's investments in any country are limited to 25% or less of its total assets. However, the fund may invest more than 25% of its assets in issuers organized in Japan or the United Kingdom or in securities quoted or denominated in the Japanese yen, the British pound and the euro. Investment of a substantial portion of the fund's assets in such countries or currencies will subject the fund to the risks of adverse securities markets, exchange rates and social, political or economic events which may occur in those countries. The fund may invest without limitation in securities of issuers located in countries with emerging economies or securities markets, but will not invest more than 25% of its total assets in securities of issuers located in any one such country.

Investment Adviser Pioneer (adviser); AEW Management and Advisors, L.P. (subadviser) The underlying funds that invest primarily in debt securities are: Pioneer Bond Fund Investment objective To provide current income from an investment grade portfolio with due regard to preservation of capital and prudent investment risk. The fund also seeks a relatively stable level of dividends; however, the level of dividends will be maintained only if consistent with preserving the investment grade quality of the fund's portfolio. Principal investment strategies The fund invests primarily in: o Debt securities issued or guaranteed by the U.S. government or its agencies and instrumentalities, o Debt securities, including convertible debt, of corporate and other issuers rated at least investment grade at the time of investment, and comparably rated commercial paper, 24 o Cash and cash equivalents, certificates of deposit, repurchase agreements maturing in one week or less and bankers' acceptances. Normally, the fund invests at least 80% of its total assets in these securities. In addition, the fund may invest up to 20% of its total assets in debt securities rated below investment grade or, if unrated, of equivalent quality as determined by Pioneer. Cash and cash equivalents include cash balances, accrued interest and receivables for items such as the proceeds, not yet received, from the sale of the fund's portfolio investments. Investment Adviser Pioneer Pioneer High Yield Fund Investment objective Maximize total return through a combination of income and capital appreciation. Principal investment strategies Normally, the fund invests at least 80% of its total assets in below investment grade (high yield) debt securities and preferred stocks. These high yield securities may be convertible into the equity securities of the issuer. 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 rated debt securities. Investment Adviser Pioneer Pioneer Short Term Income Fund Investment objective A high level of current income to the extent consistent with a relatively high level of stability of principal. Principal investment strategies The fund invests primarily in: o Debt securities issued or guaranteed by the U.S. government, its agencies or instrumentalities o Debt securities, including convertible debt, of corporate and other issuers and commercial paper o Mortgage-backed and asset-backed securities o Short-term money market instruments Normally, at least 80% of the fund's net assets are invested in debt securities that are rated investment grade at the time of purchase or cash and cash equivalents. Cash and cash equivalents may include cash balances, accrued interest and receivables for items such as the proceeds, not yet received, from the sale of the fund's portfolio investments. Investment Adviser Pioneer 25 Pioneer Cash Reserves Fund Investment objective High current income, preservation of capital and liquidity through investments in high-quality short-term securities. Principal investment strategies The fund seeks to maintain a constant net asset value of $1.00 per share by investing in high-quality, U.S. dollar denominated money market securities, including those issued by: o U.S. and foreign banks o U.S. and foreign corporate issuers o The U.S. government and its agencies and instrumentalities o Foreign governments o Multinational organizations such as the World Bank The fund may invest more than 25% of its total assets in U.S. government securities and obligations of U.S. banks. The fund may invest in any money market instrument that is a permissible investment for a money market fund under the rules of the Securities and Exchange Commission, including commercial paper, certificates of deposit, time deposits, bankers' acceptances, mortgage-backed and asset-backed securities, repurchase agreements, municipal obligations and other short-term debt securities. Investment Adviser Pioneer Pioneer Strategic Income Fund Investment objective A high level of current income. Principal investment strategies Normally, the fund invests at least 80% of its net assets (plus the amount of borrowings, if any, for investment purposes) in debt securities. The fund has the flexibility to invest in a broad range of issuers and segments of the debt securities markets. Pioneer Investment Management, Inc., the fund's investment adviser, allocates the fund's investments among the following three segments of the debt markets: o Below investment grade (high yield) securities of U.S. and non-U.S. issuers o Investment grade securities of U.S. issuers o Investment grade securities of non-U.S. issuers Pioneer's allocations among these segments of the debt markets depend upon its outlook for economic, interest rate and political trends. The fund invests primarily in: o Debt securities issued or guaranteed by the U.S. government, its agencies or instrumentalities or non-U.S. governmental entities 26 o Debt securities of U.S. and non-U.S. corporate issuers, including convertible debt o Mortgage-backed and asset-backed securities The fund's investments 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. The fund invests in securities with a broad range of maturities. Depending upon Pioneer's allocation among market segments, up to 70% of the fund's total assets may be in debt securities rated below investment grade at the time of purchase or determined to be of equivalent quality by Pioneer. Up to 20% of the fund's total assets may be invested in debt securities rated below CCC by Standard & Poor's Ratings Group or the equivalent by another 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 rated debt securities. As with all fixed income securities, the market values of convertible debt securities tend to decline as interest rates increase and, conversely, to increase as interest rates decline. However, when the market price of the common stock underlying a convertible security exceeds the conversion price, the convertible security tends to reflect the market price of the underlying common stock. Depending upon Pioneer's allocation among market segments, up to 85% of the fund's total assets may be in debt securities of non-U.S. corporate and governmental issuers, including debt securities of corporate and governmental issuers in emerging markets. Investment Adviser Pioneer 27 AmSouth Strategic Portfolios: Growth & Income Portfolio and Pioneer Ibbotson Moderate Allocation Fund PROPOSAL 1(l) Approval of Agreement and Plan of Reorganization 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-1, because it contains details that are not in the summary. Each Fund is structured as a "fund of funds," which means all of its assets are invested in other mutual funds ("underlying funds"). Your Fund invests only in other AmSouth funds. Currently, the Pioneer Fund only invests in other Pioneer Funds but is seeking an exemptive order from the Securities and Exchange Commission that would permit the Pioneer Fund to invest, in addition, in mutual funds that are not managed by Pioneer. To the extent Pioneer receives an order from the Securities and Exchange Commission that permits Pioneer to invest in such other non-Pioneer underlying funds, Pioneer and the Pioneer Fund intend to rely on such order, subject to any applicable conditions of the order. In the table below, if a row extends across the entire table, the policy disclosed applies to both your AmSouth Fund and the Pioneer Fund.

Certain of the Pioneer Funds into which the AmSouth Funds are being reorganized are not currently included in the above list of funds underlying the Pioneer Fund. Pioneer and Ibbotson may determine to include such additional Pioneer Funds in the list of permitted investments for the Pioneer Fund into which your Fund is being reorganized. Alternatively, Pioneer and Ibbotson may determine to hold those additional Pioneer Funds temporarily until the Pioneer Fund's portfolio is rebalanced. Appendix A contains a summary description of each of the underlying Pioneer funds. 5 AmSouth Strategic Portfolios: Growth & Income Portfolio Pioneer Ibbotson Moderate Allocation Fund - ----------------------------------------------------------------------------------------------------------------------------- Normally, the Fund invests substantially all of its assets in underlying funds to meet its investment objective. However, the Fund may invest a portion of its assets in cash, cash equivalents or in money market funds. The underlying funds may also invest a portion of their assets in money market funds, 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, the Fund and each of the underlying funds 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, the fund may not be able to achieve its investment objective. The Fund intends to adopt a defensive strategy when Pioneer or Ibbotson believes securities in which the fund normally invests have extraordinary risks due to political or economic factors and in other extraordinary circumstances.

Class A you can exchange Fund shares by telephone or shares may be exchanged for Class I shares of online. the same Fund or another AmSouth Fund if you become eligible to purchase Class I shares. Class I shares may be exchanged for Class A shares of the same fund. No transaction fees are currently charged for exchanges. If you sell your shares or exchange them for shares of another AmSouth fund within 7 days of the date of purchase, you will be charged a 2.00% fee on the current net asset value of the shares sold or exchanged. The fee is paid to the Fund to offset the costs associated with short-term trading, such as portfolio transaction and administrative costs. The Fund uses a "first-in, first-out" method to determine how long you have held your shares. This means that if you purchased shares on different days, the shares purchased first will be considered redeemed first for purposes of determining whether the redemption fee will be charged. The fee will be charged on all covered redemptions and exchanges, including those made through retirement plan, brokerage and other types of omnibus accounts (except where it is not practical for the plan administrator or brokerage firm to implement the fee). The Fund will not impose the redemption fee on a redemption or exchange of shares purchased upon the reinvestment of dividend and capital gain distributions.

If the account is established in the shareholder's own name, shareholders may also redeem shares of the Fund by telephone or online. 9 Comparison of Principal Risks of Investing in the Funds Because each Fund has a similar investment objective, primary investment policies and strategies, the Funds are subject to the same principal risks. You could lose money on an investment in a fund or a fund may not perform as well as other investment options. Fund of funds structure and layering of fees Each Fund is structured as a fund of funds. Each Fund's investments are focused in the underlying funds, so the Fund's investment performance is directly related to the performance of the underlying funds. Each Fund's net asset value will be affected by the performance of the equity and bond markets and the value of the mutual funds in which the fund invests. Since the Funds mainly invest in the underlying funds, as opposed to other types of securities, the Funds do not have the same flexibility in their portfolio holdings as many mutual funds. In addition, each Fund indirectly pays a portion of the expenses incurred by the underlying funds. Consequently, an investment in a Fund entails more direct and indirect expenses than a direct investment in the underlying funds. For instance, you will pay management fees and operating expenses of both the Fund and the underlying funds. The underlying funds will not necessarily make consistent investment decisions, which may also increase your costs. One underlying fund may buy the same security that another underlying fund is selling. You would indirectly bear the costs of both trades without achieving any investment purpose. These transactions may also generate taxable gains. You may receive taxable gains from portfolio transactions by the underlying funds as well as taxable gains from the fund's transactions in shares of the underlying funds. Currently, Pioneer manages all of the funds underlying the Pioneer Fund. Because the portfolio management teams of each of the underlying Pioneer funds may draw upon the resources of the same equity and fixed income analyst team or may share common investment management styles or approaches, the underlying funds may hold many common portfolio positions, reducing the diversification benefits of an asset allocation style. Equity investments Equity funds invest primarily in equity securities (such as stocks), which are more volatile and carry more risks than some other forms of investment. When the value of the stocks held by an underlying equity fund goes down, the value of your investment in the fund will be affected. The underlying equity funds have risks associated with investing in equity securities. An equity fund could underperform other investments if: o The stock market goes down (this risk may be greater in the short term) o The fund's equity investments do not have the growth potential or value characteristics originally expected o Stocks selected for income do not achieve the same return as securities selected for capital growth o The types of stocks in which the fund invests or the fund's investment approach fall out of favor with investors Fixed income investments Fixed income funds primarily invest in debt securities, such as government securities, investment grade corporate securities, junk bonds, mortgaged backed securities, asset-backed securities, and money market securities. The value of your investment in the fund will change as the value of investments of the underlying funds increases and decreases. The underlying fixed income funds have risks associated with investing in debt securities. A 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 earlier than scheduled, forcing the fund to reinvest in lower yielding securities. This is known as call or prepayment risk 10 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 The investment manager's judgment about the attractiveness, relative value or potential appreciation of a particular sector, security or investment strategy proves to be incorrect Equity securities of smaller companies Compared to large companies, small and mid-sized companies, and the market for their equity securities, are likely to: o Be more sensitive to changes in the economy, earnings results and investor expectations o Have more limited product lines and capital resources o Experience sharper swings in market values o Be harder to sell at the times and prices Pioneer thinks appropriate o Offer greater potential for loss than other U.S. equity securities Equity securities of real estate industry issuers Specific risks associated with the real estate industry include: o The U.S. or a local real estate market declines due to adverse economic conditions, overbuilding and high vacancy rates, reduced or regulated rents or other causes o Interest rates go up. Rising interest rates can adversely affect the availability and cost of financing for property acquisitions and other purposes and reduce the value of a REIT's fixed income investments o The values of properties owned by a REIT or the prospects of other real estate industry issuers may be hurt by property tax increases, zoning changes, other governmental actions, environmental liabilities, natural disasters or increased operating expenses o A REIT in an underlying fund's portfolio is, or is perceived by the market to be, poorly managed Non-U.S. securities Investing in non-U.S. issuers, including emerging market issuers, may involve unique risks compared to investing in securities of issuers in the U.S. These risks are more pronounced to the extent the fund invests in issuers in the lesser-developed emerging markets or in one region, such as Europe or the Pacific Rim. These risks may include: o Less information about the non-U.S. issuers or markets may be available due to less rigorous disclosure or accounting standards or regulatory practices 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 securities markets o Withholding and other non-U.S. taxes may decrease the fund's return High yield/below investment grade debt securities Investment in high yield securities involves substantial risk of loss. These securities are considered speculative with respect to the issuer's ability to pay interest and principal and are susceptible to default or decline in market value due to adverse economic and business developments. The market values for high yield securities tend to be very volatile, and these securities are less liquid than investment grade debt securities. For these reasons, your investment in the fund is subject to the following specific risks: o Increased price sensitivity to changing interest rates and deteriorating economic environment o Greater risk of loss due to default or declining credit quality o Adverse company specific events are more likely to render the issuer unable to make interest and/or principal payments o A negative perception of the high yield market develops, depressing the price and liquidity of high yield securities. This negative perception could last for a significant period of time 11 Derivatives Certain underlying 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. The underlying funds may use derivatives for a variety of purposes, including: o As a hedge against adverse changes in stock market prices, 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 a fund's exposure to stock market values, interest rates or currency exchange 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. Past Performance Set forth below is performance information for AmSouth Strategic Portfolios: Growth & Income Portfolio. The bar charts show how AmSouth Strategic Portfolios: Growth & Income Portfolio's total return (not including any deduction for sales charges) has varied from year to year for each full calendar year. The table shows average annual total return (before and after 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 bar charts give an indication of the risks of investing in each Fund, including the fact that you could incur a loss and experience volatility of returns year to year.

Pioneer Ibbotson Moderate Allocation Fund -- Class A Shares Calendar Year Total Returns Pioneer Ibbotson Moderate Allocation Fund began investment operations in August 2004. Since the Pioneer Fund has conducted investment operations for less than one calendar year, it may not disclose any performance information in this prospectus. The fund's performance will vary from year to year. Past performance does not necessarily indicate how a fund will perform in the future. As a shareowner, you may lose or make money on your investment.

The table above shows the impact of taxes on AmSouth Strategic Portfolios: Growth & Income Portfolio's returns. After-tax returns are only shown for Class A shares and Class I shares and may vary for Class B shares. The Fund's after-tax returns are calculated using the highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. In certain cases, the figure representing "Return After Taxes on Distributions and Sale of Fund Shares" may be higher than the other return figures for the same period. A higher after-tax return results when a capital loss occurs upon redemption and translates into an assumed tax deduction that benefits the shareholder. Please note that actual after-tax returns depend on an investor's tax situation and may differ from those shown. Also note that 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. 13 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 the AmSouth Strategic Portfolios: Growth & Income Portfolio, the expenses of AmSouth Strategic Portfolios: Growth & Income Portfolio for the period ended January 31, 2005 and (ii) for Pioneer Ibbotson Moderate Allocation Fund, the estimated expenses for the period ended January 31, 2005. Future expenses for all share classes may be greater or less. Shareholders of AmSouth Strategic Portfolios: Moderate Growth & Income Portfolio are also being asked to approve the reorganization of their fund into Pioneer Ibbotson Moderate Allocation Fund. The tables also show (1) the pro forma expenses of the combined Fund assuming the Reorganization occurred on January 31, 2005 and (2) the pro forma expenses of the combined Fund assuming the reorganization of AmSouth Strategic Portfolios: Moderate Growth & Income Portfolio into Pioneer Ibbotson Moderate Allocation Fund also occurred on January 31, 2005.

(2) Sales charges may be reduced depending upon the amount invested or, in certain circumstances, waived. Class A Shares bought as part of an investment of $1 million or more are not subject to an initial sales charge, but may be charged a CDSC of 1.00% if sold within one year of purchase. (3) For Class B shares purchased prior to the combination of AmSouth Funds with ISG Funds, the CDSC on such Class B Shares held continuously declines over six years, starting with year one and ending in year seven from: 4%, 3%, 3%, 2%, 2%, 1%. For all other Class B shares held continuously, the CDSC declines over six years, starting with year one and ending in year seven from: 5%, 4%, 3%, 3%, 2%, 1%. Eight years after purchase (seven years in the case of shares acquired in the ISG combination), Class B shares automatically convert to Class A shares. 15 (4) To discourage short-term trading, a redemption fee of 2.00% will be charged on sales or exchanges of Class A, Class B and Class I shares of your AmSouth Fund made within 7 days of the date of purchase. A wire transfer fee of $7.00 will be deducted from the amount of your redemption if you request a wire transfer. (5) Other expenses for your AmSouth Fund are being limited to 0.32% for Class A shares, 0.31% for Class B shares and 0.27% for Class I shares. Any fee waiver or expense reimbursement arrangement is voluntary and may be discontinued at any time. Pioneer has contractually agreed not to impose all or a portion of its fees or to limit other direct ordinary operating expenses to the extent required to reduce expenses, other than "Estimated average expense ratio of underlying funds," to 0.74% of the average daily net assets attributable to Class A shares and 1.64% of average daily net assets attributable to Class B shares. This expense limitation is in effect for Class A shares until December 1, 2008 and in effect for Class B until December 1, 2006. There can be no assurance that Pioneer will extend these expense limitations past such dates. The expense limitation does not limit the expenses of the underlying funds indirectly incurred by a shareholder. (6) The management fee payable by the Pioneer Fund is equal to 0.13% of average daily net assets attributable to the Pioneer Fund's investments in underlying funds managed by Pioneer and cash and 0.17% of average daily net assets attributable to other investments, including underlying funds that are not managed by Pioneer, with breakpoints at incremental asset levels. Since initially all of the underlying funds are managed by Pioneer, the management fee will initially be 0.13% of average daily net assets. (7) The Pioneer Fund's total annual operating expenses in the table have not been reduced by any expense offset arrangements. (8) Class Y shares of the Pioneer Fund are being offered for the first time in connection with the Reorganization. 16 The hypothetical example below helps you compare the cost of investing in each Fund. It assumes that: (a) you invest $10,000 in each Fund for the time periods shown, (b) you reinvest all dividends and distributions, (c) your investment has a 5% return each year, and (d) each Fund's gross operating expenses remain the same. The examples are for comparison purposes only and are not a representation of either Fund's actual expenses or returns, either past or future.

The Trustees considered the following matters, among others, in approving the proposal. First, AAMI, the investment adviser to your Amsouth Fund, informed the Trustees that it does not intend to continue to provide investment advisory services to the AmSouth Funds. Consequently, a change in your Fund's investment adviser was necessary. In the absence of the Reorganization, such a change would be more likely to motivate shareholders invested in reliance on AAMI's role to withdraw from the Fund, thereby reducing fund size and increasing fund expense ratios. Second, the resources of Pioneer. At December 31, 2004, Pioneer managed over 80 investment companies and accounts with approximately $42 billion in assets. Pioneer is part of the global asset management group of UniCredito Italiano S.p.A., one of the largest banking groups in Italy, providing investment management and financial services to mutual funds, institutional and other clients. As of December 31, 2004, assets under management of UniCredito Italiano S.p.A. were approximately $175 billion worldwide. Shareholders of your AmSouth Fund would become part of a significantly larger family of funds that offers a more diverse array of investment options and enhanced shareholder account options. The Pioneer family of mutual funds offers over 80 funds, including domestic and international equity and fixed income funds and a money market fund that will be available to your AmSouth Fund's shareholders through exchanges. Third, Pioneer Ibbotson Moderate Allocation Fund's management fee (0.17% of average daily net assets) is lower than the advisory fee of your Fund (0.20% of average daily net assets). Both the historical and estimated pro forma expenses of the Pioneer Fund, after giving effect to the Reorganization, on a gross and net basis are lower than your Fund's gross and net 17 operating expenses. The aggregate Rule 12b-1 distribution and shareholder servicing fees and non-Rule 12b-1 shareholder servicing fees paid by the Class A and Class B shares of both Funds are the same. Moreover, your AmSouth Fund's Class I shares pay a non 12b-1 shareholder servicing fee that is not paid by the Pioneer Fund's Class Y shares. Fourth, because of Pioneer distribution arrangements, Pioneer Fund has greater potential to further increase the assets compared to your Fund. Further assets growth is anticipated to further reduce the combined Fund's gross operating expenses per share. Fifth, the Class A, B and Y shares of the Pioneer Fund received in the Reorganization will provide AmSouth Fund shareholders with exposure to a similar investment product as they currently have. The Trustees also noted that the allocation decisions are made by Ibbotson, a leading asset allocation adviser, and that the Pioneer Fund intends, as soon as permitted by the Securities and Exchange Commission, to include unaffiliated mutual funds as underlying funds. Sixth, the transaction is structured to qualify as a tax-free reorganization under Section 368(a) of the Internal Revenue Code of 1986 and therefore will not be treated as a taxable sale of your AmSouth shares. Although the Reorganization will result in a per share decrease in capital loss carryforwards, the potential negative tax consequences of this aspect of the Reorganization are outweighed by the advantages of the Reorganization. The Reorganization will also result in a per share decrease in net unrealized capital gains. Pioneer and AmSouth Bank will pay all costs of preparing and printing the Funds' proxy statements and solicitation costs incurred by the Funds in connection with the Reorganization. AAMI will otherwise be responsible for all costs and expenses of AmSouth Fund in connection with the Reorganization. The Trustees also considered that Pioneer and AmSouth Bank will benefit from the Reorganization. See "Will Pioneer and AmSouth Bank Benefit from the Reorganizations." The Board of Trustees of the Pioneer Fund also considered that the Reorganization presents an excellent opportunity for the Pioneer Fund to acquire investment assets 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 the Pioneer Fund and its shareholders. CAPITALIZATION The following table sets forth the capitalization of each Fund as of May 31, 2005, and the pro forma combined Fund as of May 31, 2005. The table also sets forth the pro forma capitalization of the combined Fund as of May 31, 2005, assuming the shareholders of AmSouth Strategic Portfolios: Moderate Growth & Income Portfolio approve the reorganization of their fund into Pioneer Ibbotson Moderate Allocation Fund.

The table should not be relied upon to determine the amount of the Pioneer Fund's shares that will actually be received and distributed. BOARD'S EVALUATION AND RECOMMENDATION For the reasons described above, the Trustees, including the Independent Trustees, approved the Reorganization. In particular, the Trustees determined that the Reorganization is in the best interests of your AmSouth Fund. Similarly, the Board of Trustees of the Pioneer Fund, including its Independent Trustees, approved the Reorganization. They also determined that the Reorganization is in the best interests of the Pioneer Fund. The Trustees recommend that the shareholders of your AmSouth Fund vote FOR the proposal to approve the Agreement and Plan of Reorganization. 19 Information about the underlying funds The following is intended to summarize the investment objectives and primary strategies of, and to provide you with certain other information about, the underlying funds. These summaries do not reflect all of the investment policies and strategies that are disclosed in each underlying fund's prospectus, and are not an offer of the underlying funds' shares. The underlying funds in which the funds intend to invest may change from time to time and the funds may invest in underlying funds in addition to those described below at the discretion of Pioneer without prior notice to or approval of shareholders. The prospectus and SAI for each underlying fund is available on the SEC's website as well as on our website at www.pioneerfunds.com. Each underlying fund normally will be invested according to its investment strategy. However, an underlying fund also may have the ability to invest without limitation in money market instruments or other investments for temporary, defensive purposes. The underlying funds that invest primarily in equity securities are: Pioneer Fund Investment objective Reasonable income and capital growth. Principal investment strategies The fund invests in a broad list of carefully selected, reasonably priced securities rather than in securities whose prices reflect a premium resulting from their current market popularity. The fund invests the major portion of its assets in equity securities, primarily of U.S. issuers. For purposes of the fund's investment policies, equity securities include common stocks, convertible debt and other equity instruments, such as depositary receipts, warrants, rights and preferred stocks. Investment Adviser Pioneer Pioneer Research Fund Investment objective Long-term capital growth. Principal investment strategies Normally, the fund invests at least 80% of its assets in equity securities, primarily of U.S. issuers. For purposes of the fund's investment policies, equity securities include common stocks, convertible debt and other equity instruments, such as preferred stocks, depositary receipts, rights and warrants. Investment Adviser Pioneer 20 Pioneer Growth Leaders Fund Investment objective Long term capital growth. Principal investment strategies Normally, the fund invests at least 80% of its net assets (plus the amount of borrowings, if any, for investment purposes) in common and preferred stocks and securities convertible into stocks. Securities convertible into stocks include depositary receipts on stocks, convertible debt securities, warrants and rights. The fund offers a broad investment program for the equity portion of an investor's portfolio, with an emphasis on mid and large capitalization issuers traded in the U.S. However, the fund may invest in issuers of any capitalization. Investment Adviser Pioneer (adviser); L. Roy Papp & Associates, LLP (subadviser) Pioneer Strategic Growth Fund Investment objective Long term capital growth. Principal investment strategies Normally, the fund invests at least 80% of its net assets (plus the amount of borrowings, if any, for investment purposes) in equity securities of U.S. issuers. The fund invests primarily in securities, traded in the U.S., of issuers that the subadviser believes have substantial international activities. In evaluating whether an issuer has substantial international activities, the subadviser considers the degree to which the issuer has non-U.S. reported sales and revenues, operating earnings or tangible assets. The fund may invest up to 20% of the value of its investments in equity securities of non-U.S. issuers that are traded in U.S. markets. Investment Adviser Pioneer (adviser); L. Roy Papp & Associates, LLP (subadviser) Pioneer Oak Ridge Large Cap Growth Fund Investment objective Capital appreciation. Principal investment strategies Normally, the fund invests at least 80% of its net assets (plus the amount of borrowings, if any, for investment purposes) in equity securities of large capitalization U.S. companies. Large capitalization companies have market capitalizations at the time of acquisition of $3 billion or more. The fund anticipates that the average weighted market capitalization of the companies in the fund's portfolio will be significantly higher that $3 billion. The equity securities in which the fund principally invests are common stocks, preferred stocks, depositary receipts and convertible debt, but the fund may invest in other types of equity securities to a lesser extent, such as warrants and rights. Investment Adviser Pioneer (adviser); Oak Ridge Investments, LLC (subadviser) 21 Pioneer AmPac Growth Fund Investment objective Long-term capital growth. Principal investment strategies Normally, the fund invests at least 80% of its net assets (plus the amount of borrowings, if any, for investment purposes) in equity securities of issuers that have substantial sales to, or receive significant income from, countries within the Pacific Rim. These issuers meet one of the following criteria: o 50% or more of the issuer's earnings or sales are attributed to, or assets are situated in, Pacific Rim countries (including the U.S. and other countries bordering the Pacific Ocean, such as China and Indonesia) o 50% or more of the issuer's earnings or sales are attributed to, or assets are situated in, Pacific Rim countries other than the U.S. The fund also may invest up to 30% of the value of its investments in equity securities of non-U.S. issuers that are traded in U.S. markets. Investment Adviser Pioneer (adviser); L. Roy Papp & Associates, LLP (subadviser) Pioneer Value Fund Investment objective Reasonable income and capital growth. Principal investment strategies The fund seeks to invest in a broad list of carefully selected, reasonably priced securities rather than in securities whose prices reflect a premium resulting from their current market popularity. The fund invests the major portion of its assets in equity securities, primarily of U.S. issuers. For purposes of the fund's investment policies, equity securities include common stocks, convertible debt and other equity instruments, such as depositary receipts, warrants, rights and preferred stocks. Investment Adviser Pioneer Pioneer Mid Cap Growth Fund Investment objective Capital growth by investing in a diversified portfolio of securities consisting primarily of common stocks. Principal investment strategies Normally, the fund invests at least 80% of its total assets in equity securities of mid-size companies, that is, companies with market values within the range of market values of issuers included in the Russell Midcap Growth Index. For purposes of the fund's investment policies, equity securities include common stocks, convertible debt and other equity instruments, such as depositary receipts, warrants, rights, interests in real estate investment trusts (REITs) and preferred stocks. 22 Investment Adviser Pioneer Pioneer Cullen Value Fund Investment objective Capital appreciation. Current income is a secondary objective. Principal investment strategies The fund invests primarily in equity securities. The fund may invest a significant portion of its assets in equity securities of medium- and large-capitalization companies. Consequently, the fund will be subject to the risks of investing in companies with market capitalizations of $1.5 billion or more. For purposes of the fund's investment policies, equity securities include common stocks, convertible debt and other equity instruments, such as depositary receipts, warrants, rights, equity interests in real estate investment trusts (REITs) and preferred stocks. The fund may invest up to 30% of its total assets in securities of non-U.S. issuers. Up to 5% of the fund's total assets may be invested in securities of emerging market issuers. The fund may invest in securities of Canadian issuers to the same extent as securities of U.S. issuers. Investment Adviser Pioneer Pioneer Mid Cap Value Fund Investment objective Capital appreciation by investing in a diversified portfolio of securities consisting primarily of common stocks. Principal investment strategies Normally, the fund invests at least 80% of its total assets in equity securities of mid-size companies, that is companies with market values within the range of market values of companies included in the Russell Midcap Value Index. The fund focuses on issuers with capitalizations within the $1 billion to $10 billion range, and that range will change depending on market conditions. The equity securities in which the fund principally invests are common stocks, preferred stocks, depositary receipts and convertible debt, but the fund may invest in other types of equity securities to a lesser extent, such as warrants and rights. Investment Adviser Pioneer Pioneer Small and Mid Cap Growth Fund Investment objective Long-term capital growth. Principal investment strategies Normally, the fund invests at least 80% of its net assets (plus the amount of borrowings, if any, for investment purposes) in equity securities of small and mid-capitalization issuers, that is those with market values, at the time of investment, that do not exceed the market capitalization of the largest company within the S&P Mid Cap 400 Index. The size of the companies in the index may change dramatically as a result of market conditions and the composition of the index. The fund's investments will 23 not be confined to securities issued by companies included in an index. For purposes of the fund's investment policies, equity securities include common stocks, convertible debt and other equity instruments, such as depositary receipts, warrants, rights and preferred stocks. Investment Adviser Pioneer (adviser); L. Roy Papp & Associates, LLP (subadviser) Pioneer Oak Ridge Small Cap Growth Fund Investment objective Capital appreciation. Principal investment strategies Normally, the fund invests at least 80% of its net assets (plus the amount of borrowings, if any, for investment purposes) in equity securities of small capitalization U.S. companies with market capitalizations of $2 billion or less. For purposes of the fund's investment policies, equity securities include common stocks, convertible debt and other equity instruments, such as depositary receipts, warrants, rights and preferred stocks. Small capitalization companies have market capitalizations at the time of acquisition of $2 billion or less. The equity securities in which the fund principally invests are common stocks, preferred stocks, depositary receipts and convertible debt, but the fund may invest in other types of equity securities to a lesser extent, such as warrants and rights. Investment Adviser Pioneer (adviser); Oak Ridge Investments, LLC (subadviser) Pioneer Small Cap Value Fund Investment objective Capital growth by investing in a diversified portfolio of securities consisting primarily of common stocks. Principal investment strategies Normally, the fund invests at least 80% of its net assets (plus the amount of borrowings, if any, for investment purposes) in equity securities of small companies. Small companies are those with market values, at the time of investment, that do not exceed the greater of the market capitalization of the largest company within the Russell 2000 Index or the 3-year rolling average of the market capitalization of the largest company within the Russell 2000 Index as measured at the end of the preceding month. The Russell 2000 Index measures the performance of the 2,000 smallest companies in the Russell 3000 Index.

Investment Adviser Pioneer (adviser); AEW Management and Advisors, L.P. (subadviser) The underlying funds that invest primarily in debt securities are: Pioneer Bond Fund Investment objective To provide current income from an investment grade portfolio with due regard to preservation of capital and prudent investment risk. The fund also seeks a relatively stable level of dividends; however, the level of dividends will be maintained only if consistent with preserving the investment grade quality of the fund's portfolio. Principal investment strategies The fund invests primarily in: o Debt securities issued or guaranteed by the U.S. government or its agencies and instrumentalities, o Debt securities, including convertible debt, of corporate and other issuers rated at least investment grade at the time of investment, and comparably rated commercial paper, 26 o Cash and cash equivalents, certificates of deposit, repurchase agreements maturing in one week or less and bankers' acceptances. Normally, the fund invests at least 80% of its total assets in these securities. In addition, the fund may invest up to 20% of its total assets in debt securities rated below investment grade or, if unrated, of equivalent quality as determined by Pioneer. Cash and cash equivalents include cash balances, accrued interest and receivables for items such as the proceeds, not yet received, from the sale of the fund's portfolio investments. Investment Adviser Pioneer Pioneer High Yield Fund Investment objective Maximize total return through a combination of income and capital appreciation. Principal investment strategies Normally, the fund invests at least 80% of its total assets in below investment grade (high yield) debt securities and preferred stocks. These high yield securities may be convertible into the equity securities of the issuer. 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 rated debt securities. Investment Adviser Pioneer Pioneer Short Term Income Fund Investment objective A high level of current income to the extent consistent with a relatively high level of stability of principal. Principal investment strategies The fund invests primarily in: o Debt securities issued or guaranteed by the U.S. government, its agencies or instrumentalities o Debt securities, including convertible debt, of corporate and other issuers and commercial paper o Mortgage-backed and asset-backed securities o Short-term money market instruments Normally, at least 80% of the fund's net assets are invested in debt securities that are rated investment grade at the time of purchase or cash and cash equivalents. Cash and cash equivalents may include cash balances, accrued interest and receivables for items such as the proceeds, not yet received, from the sale of the fund's portfolio investments. Investment Adviser Pioneer 27 Pioneer Cash Reserves Fund Investment objective High current income, preservation of capital and liquidity through investments in high-quality short-term securities. Principal investment strategies The fund seeks to maintain a constant net asset value of $1.00 per share by investing in high-quality, U.S. dollar denominated money market securities, including those issued by: o U.S. and foreign banks o U.S. and foreign corporate issuers o The U.S. government and its agencies and instrumentalities o Foreign governments o Multinational organizations such as the World Bank The fund may invest more than 25% of its total assets in U.S. government securities and obligations of U.S. banks. The fund may invest in any money market instrument that is a permissible investment for a money market fund under the rules of the Securities and Exchange Commission, including commercial paper, certificates of deposit, time deposits, bankers' acceptances, mortgage-backed and asset-backed securities, repurchase agreements, municipal obligations and other short-term debt securities. Investment Adviser Pioneer Pioneer Strategic Income Fund Investment objective A high level of current income. Principal investment strategies Normally, the fund invests at least 80% of its net assets (plus the amount of borrowings, if any, for investment purposes) in debt securities. The fund has the flexibility to invest in a broad range of issuers and segments of the debt securities markets. Pioneer Investment Management, Inc., the fund's investment adviser, allocates the fund's investments among the following three segments of the debt markets: o Below investment grade (high yield) securities of U.S. and non-U.S. issuers o Investment grade securities of U.S. issuers o Investment grade securities of non-U.S. issuers Pioneer's allocations among these segments of the debt markets depend upon its outlook for economic, interest rate and political trends. The fund invests primarily in: o Debt securities issued or guaranteed by the U.S. government, its agencies or instrumentalities or non-U.S. governmental entities 28 o Debt securities of U.S. and non-U.S. corporate issuers, including convertible debt o Mortgage-backed and asset-backed securities The fund's investments 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. The fund invests in securities with a broad range of maturities. Depending upon Pioneer's allocation among market segments, up to 70% of the fund's total assets may be in debt securities rated below investment grade at the time of purchase or determined to be of equivalent quality by Pioneer. Up to 20% of the fund's total assets may be invested in debt securities rated below CCC by Standard & Poor's Ratings Group or the equivalent by another 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 rated debt securities. As with all fixed income securities, the market values of convertible debt securities tend to decline as interest rates increase and, conversely, to increase as interest rates decline. However, when the market price of the common stock underlying a convertible security exceeds the conversion price, the convertible security tends to reflect the market price of the underlying common stock. Depending upon Pioneer's allocation among market segments, up to 85% of the fund's total assets may be in debt securities of non-U.S. corporate and governmental issuers, including debt securities of corporate and governmental issuers in emerging markets.

You should read carefully the entire Proxy Statement/Prospectus, including the form of Agreement and Plan of Reorganization attached as EXHIBIT A-1, because it contains details that are not in the summary. Each Fund is structured as a "fund of funds," which means all of its assets are invested in other mutual funds ("underlying funds"). Your Fund invests only in other AmSouth funds. Currently, the Pioneer Fund only invests in other Pioneer funds but is seeking an exemptive order from the Securities and Exchange Commission that would permit the Pioneer Fund to invest, in addition, in mutual funds that are not managed by Pioneer. To the extent that Pioneer receives an order from the Securities and Exchange Commission that permits Pioneer to invest in such other non-Pioneer underlying funds, Pioneer and the Pioneer Fund intend to rely on such order, subject to any applicable conditions of the order. In the table below, if a row extends across the entire table, the policy disclosed applies to both your AmSouth Fund and the Pioneer Fund.

Certain of the Pioneer Funds into which the AmSouth Funds are being reorganized are not currently included in the above list of funds underlying the Pioneer Fund. Pioneer and Ibbotson may determine to include such additional Pioneer Funds in the list of permitted investments for the Pioneer Fund into which your Fund is being reorganized. Alternatively, Pioneer and Ibbotson may determine to hold those additional Pioneer Funds temporarily until the Pioneer Fund's portfolio is rebalanced. Appendix A contains a summary description of each of the underlying Pioneer funds. 5 AmSouth Strategic Portfolios: Moderate Growth Pioneer Ibbotson Moderate Allocation Fund & Income Portfolio - ------------------------------------------------------------------------------------------------------------------------------ Normally, the Fund invests substantially all of its assets in underlying funds to meet its investment objective. However, the Fund may invest a portion of its assets in cash, cash equivalents or in money market funds. The underlying funds may also invest a portion of their assets in money market funds, 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, the Fund and each of the underlying funds 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, the Fund may not be able to achieve its investment objective. The Fund intends to adopt a defensive strategy when Pioneer or Ibbotson believes securities in which the Fund normally invests have extraordinary risks due to political or economic factors and in other extraordinary circumstances.

Class I shares may be exchanged for Class A shares of the same fund. No transaction fees are currently charged for exchanges. If you sell your shares or exchange them for shares of another AmSouth Fund within 7 days of the date of purchase, you will be charged a 2.00% fee on the current net asset value of the shares sold or exchanged. The fee is paid to the Fund to offset the costs associated with short-term trading, such as portfolio transaction and administrative costs. The Fund uses a "first-in, first-out" method to determine how long you have held your shares. This means that if you purchased shares on different days, the shares purchased first will be considered redeemed first for purposes of determining whether the redemption fee will be charged. The fee will be charged on all covered redemptions and exchanges, including those made through retirement plan, brokerage and other types of omnibus accounts (except where it is not practical for the plan administrator or brokerage firm to implement the fee). The Fund will not impose the redemption fee on a redemption or exchange of shares purchased upon the reinvestment of dividend and capital gain distributions. Selling shares Shares of each Fund are sold at the net asset value per share next calculated after the Fund receives your request in good order. You may sell your shares by contacting the Normally, your investment firm will send your Fund directly in writing or by telephone or by request to sell shares to PIMSS. You can also contacting a financial intermediary as sell your shares by contacting the Fund described in the Fund's prospectus. directly if your account is registered in your name. If the account is established in the shareholder's own name, shareholders may also redeem shares of the Pioneer Fund by telephone or online. Comparison of Principal Risks of Investing in the Funds Because each Fund has a similar investment objective, primary investment policies and strategies, the Funds are subject to the same principal risks. You could lose money on an investment in a Fund or a Fund may not perform as well as other investment options. Fund of funds structure and layering of fees 9 Each Fund is structured as a fund of funds. Each Fund's investments are focused in the underlying funds, so the Fund's investment performance is directly related to the performance of the underlying funds. Each Fund's net asset value will be affected by the performance of the equity and bond markets and the value of the mutual funds in which the fund invests. Since the Funds mainly invest in the underlying funds, as opposed to other types of securities, the Funds do not have the same flexibility in their portfolio holdings as many mutual funds. In addition, each Fund indirectly pays a portion of the expenses incurred by the underlying funds. Consequently, an investment in a Fund entails more direct and indirect expenses than a direct investment in the underlying funds. For instance, you will pay management fees and operating expenses of both the Fund and the underlying funds. The underlying funds will not necessarily make consistent investment decisions, which may also increase your costs. One underlying fund may buy the same security that another underlying fund is selling. You would indirectly bear the costs of both trades without achieving any investment purpose. These transactions may also generate taxable gains. You may receive taxable gains from portfolio transactions by the underlying funds as well as taxable gains from the Fund's transactions in shares of the underlying funds. Currently, Pioneer manages all of the funds underlying the Pioneer Fund. Because the portfolio management teams of each of the underlying Pioneer funds may draw upon the resources of the same equity and fixed income analyst team or may share common investment management styles or approaches, the underlying funds may hold many common portfolio positions, reducing the diversification benefits of an asset allocation style. Equity investments Equity funds invest primarily in equity securities (such as stocks), which are more volatile and carry more risks than some other forms of investment. When the value of the stocks held by an underlying equity fund goes down, the value of your investment in the fund will be affected. The underlying equity funds have risks associated with investing in equity securities. An equity fund could underperform other investments if: o The stock market goes down (this risk may be greater in the short term) o The fund's equity investments do not have the growth potential or value characteristics originally expected o Stocks selected for income do not achieve the same return as securities selected for capital growth o The types of stocks in which the fund invests or the fund's investment approach fall out of favor with investors Fixed income investments Fixed income funds primarily invest in debt securities, such as government securities, investment grade corporate securities, junk bonds, mortgaged backed securities, asset-backed securities, and money market securities. The value of your investment in the fund will change as the value of investments of the underlying funds increases and decreases. The underlying fixed income funds have risks associated with investing in debt securities. A 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 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 The investment manager's judgment about the attractiveness, relative value or potential appreciation of a particular sector, security or investment strategy proves to be incorrect Equity securities of smaller companies 10 Compared to large companies, small and mid-sized companies, and the market for their equity securities, are likely to: o Be more sensitive to changes in the economy, earnings results and investor expectations o Have more limited product lines and capital resources o Experience sharper swings in market values o Be harder to sell at the times and prices Pioneer thinks appropriate o Offer greater potential for loss than other U.S. equity securities Equity securities of real estate industry issuers Specific risks associated with the real estate industry include: o The U.S. or a local real estate market declines due to adverse economic conditions, overbuilding and high vacancy rates, reduced or regulated rents or other causes o Interest rates go up. Rising interest rates can adversely affect the availability and cost of financing for property acquisitions and other purposes and reduce the value of a REIT's fixed income investments o The values of properties owned by a REIT or the prospects of other real estate industry issuers may be hurt by property tax increases, zoning changes, other governmental actions, environmental liabilities, natural disasters or increased operating expenses o A REIT in an underlying fund's portfolio is, or is perceived by the market to be, poorly managed Non-U.S. securities Investing in non-U.S. issuers, including emerging market issuers, may involve unique risks compared to investing in securities of issuers in the U.S. These risks are more pronounced to the extent the fund invests in issuers in the lesser-developed emerging markets or in one region, such as Europe or the Pacific Rim. These risks may include: o Less information about the non-U.S. issuers or markets may be available due to less rigorous disclosure or accounting standards or regulatory practices 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 securities markets o Withholding and other non-U.S. taxes may decrease the fund's return High yield/below investment grade debt securities Investment in high yield securities involves substantial risk of loss. These securities are considered speculative with respect to the issuer's ability to pay interest and principal and are susceptible to default or decline in market value due to adverse economic and business developments. The market values for high yield securities tend to be very volatile, and these securities are less liquid than investment grade debt securities. For these reasons, your investment in the fund is subject to the following specific risks: o Increased price sensitivity to changing interest rates and deteriorating economic environment o Greater risk of loss due to default or declining credit quality o Adverse company specific events are more likely to render the issuer unable to make interest and/or principal payments o A negative perception of the high yield market develops, depressing the price and liquidity of high yield securities. This negative perception could last for a significant period of time Derivatives Certain underlying 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. The underlying funds may use derivatives for a variety of purposes, including: o As a hedge against adverse changes in stock market prices, 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 11 Even a small investment in derivatives can have a significant impact on a fund's exposure to stock market values, interest rates or currency exchange 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 table above shows the impact of taxes on AmSouth Strategic Portfolios: Moderate Growth & Income Portfolio's returns. After-tax returns are only shown for Class A shares and Class I shares and may vary for Class B shares. The Fund's after-tax returns are calculated using the highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. In certain cases, the figure representing "Return After Taxes on Distributions and Sale of Fund Shares" may be higher than the other return figures for the same period. A higher after-tax return results when a capital loss occurs upon redemption and translates into an assumed tax deduction that benefits the shareholder. Please note that actual after-tax returns depend on an investor's tax situation and may differ from those shown. Also note that 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. 13 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) Sales charges may be reduced depending upon the amount invested or, in certain circumstances, waived. Class A shares of the Pioneer Fund bought as part of an investment of $1 million or more are not subject to an initial sales charge, but may be charged a CDSC of 1.00% if sold within one year of purchase. (3) For Class B shares purchased prior to the combination of AmSouth Funds with ISG Funds, the CDSC on such Class B shares held continuously declines over six years, starting with year one and ending in year seven from: 4%, 3%, 3%, 2%, 2%, 1%. For all other Class B shares held continuously, the CDSC declines 15 over six years, starting with year one and ending in year seven from: 5%, 4%, 3%, 3%, 2%, 1%. Eight years after purchase (seven years in the case of shares acquired in the ISG combination), Class B shares automatically convert to Class A shares. (4) To discourage short-term trading, a redemption fee of 2.00% will be charged on sales or exchanges of Class A, Class B and Class I shares of your AmSouth Fund made within 7 days of the date of purchase. A wire transfer fee of $7.00 will be deducted from the amount of your redemption if you request a wire transfer. (5) Other expenses for your AmSouth Fund are being limited to 0.33% for Class A shares, 0.33% for Class B shares and 0.28% for Class I shares. Any fee waiver or expense reimbursement arrangement is voluntary and may be discontinued at any time. Pioneer has contractually agreed not to impose all or a portion of its fees or to limit other direct ordinary operating expenses to the extent required to reduce expenses, other than "Estimated average expense ratio of underlying funds," to 0.74% of the average daily net assets attributable to Class A shares and 1.52% of average daily net assets attributable to Class B shares. This expense limitation is in effect for Class A shares until December 1, 2008 and in effect for Class B until December 1, 2006. There can be no assurance that Pioneer will extend these expense limitations past such dates. The expense limitation does not limit the expenses of the underlying funds indirectly incurred by a shareholder. (6) The management fee payable by the Pioneer Fund is equal to 0.13% of average daily net assets attributable to the Pioneer Fund's investments in underlying funds managed by Pioneer and cash and 0.17% of average daily net assets attributable to other investments, including underlying funds that are not managed by Pioneer, with breakpoints at incremental asset levels. Since initially all of the underlying funds are managed by Pioneer, the management fee will initially be 0.13% of average daily net assets. (7) The Pioneer Fund's total annual operating expenses in the table have not been reduced by any expense offset arrangements. (8) Class Y shares of the Pioneer Fund are being offered for the first time in connection with the Reorganization. 16 The hypothetical example below helps you compare the cost of investing in each Fund. It assumes that: (a) you invest $10,000 in each Fund for the time periods shown, (b) you reinvest all dividends and distributions, (c) your investment has a 5% return each year, and (d) each Fund's gross operating expenses remain the same. The examples are for comparison purposes only and are not a representation of either Fund's actual expenses or returns, either past or future.

The Trustees considered the following matters, among others, in approving the proposal. First, AAMI, the investment adviser to your AmSouth Fund, informed the Trustees that it does not intend to continue to provide investment advisory services to the AmSouth Funds. Consequently, a change in your Fund's investment adviser was necessary. In the absence of the Reorganization, such a change would be more likely to motivate shareholders invested in reliance on AAMI's role to withdraw from the Fund, thereby reducing fund size and increasing fund expense ratios. Second, the resources of Pioneer. At December 31, 2004, Pioneer managed over 80 investment companies and accounts with approximately $42 billion in assets, including $15.7 billion in fixed income securities. Pioneer is part of the global asset management group of UniCredito Italiano S.p.A., one of the largest banking groups in Italy, providing investment management and financial services to mutual funds, institutional and other clients. As of December 31, 2004, assets under management of UniCredito Italiano S.p.A. were approximately $175 billion worldwide. Shareholders of your AmSouth Fund would become part of a significantly larger family of funds that offers a more diverse array of investment options and enhanced shareholder account options. The Pioneer family of mutual funds offers over 80 funds, including domestic and international equity and fixed income funds and a money market fund that will be available to your AmSouth Fund's shareholders through exchanges. 17 Third, Pioneer Ibbotson Moderate Allocation Fund's management fee (0.17% of average daily net assets) is lower than the advisory fee of your Fund (0.20% of average daily net assets). Both the historical and estimated pro forma expenses of the Pioneer Fund, after giving effect to the Reorganization, on a gross and net basis are lower than your Fund's gross and net operating expenses. The aggregate Rule 12b-1 distribution and shareholder servicing fees and non-Rule 12b-1 shareholder servicing fees paid by the Class A and Class B shares of both Funds are the same. Moreover, your AmSouth Fund's Class I shares pay a non 12b-1 shareholder servicing fee that is not paid by the Pioneer Fund's Class Y shares. Fourth, because of Pioneer distribution arrangements, Pioneer Fund has greater potential to further increase the assets compared to your Fund. Further assets growth is anticipated to further reduce the combined Fund's gross operating expenses per share. Fifth, the Class A, B and Y shares of the Pioneer Fund received in the Reorganization will provide AmSouth Fund shareholders with exposure to a similar investment product as they currently have. The Trustees also noted that the allocation decision was made by Ibbotson, a leading asset allocation adviser, and that the Pioneer Fund intends, as soon as permitted by the SEC, to include unaffiliated mutual funds as underlying funds. Sixth, the transaction is structured to qualify as a tax-free reorganization under Section 368(a) of the Internal Revenue Code of 1986 and therefore will not be treated as a taxable sale of your AmSouth shares. Pioneer and AmSouth Bank will pay all costs of preparing and printing the Funds' proxy statements and solicitation costs incurred by the Funds in connection with the Reorganization. AAMI will otherwise be responsible for all costs and expenses of AmSouth Fund in connection with the Reorganization. The Trustees also considered that Pioneer and AmSouth Bank will benefit from the Reorganization. See "Will Pioneer and AmSouth Bank Benefit from the Reorganizations." The Board of Trustees of the Pioneer Fund also considered that the Reorganization presents an excellent opportunity for the Pioneer Fund to acquire investment assets 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 the Pioneer Fund and its shareholders. CAPITALIZATION The following table sets forth the capitalization of each Fund as of May 31, 2005, and the pro forma combined Fund as of May 31, 2005. The table also sets forth the pro forma capitalization of the combined Fund as of May 31, 2005, assuming the shareholders of AmSouth Strategic Portfolios: Growth & Income Portfolio approve the reorganization of their fund into Pioneer Ibbotson Moderate Allocation Fund.

The table should not be relied upon to determine the amount of the Pioneer Fund's shares that will actually be received and distributed. BOARD'S EVALUATION AND RECOMMENDATION For the reasons described above, the Trustees, including the Independent Trustees, approved the Reorganization. In particular, the Trustees determined that the Reorganization is in the best interests of your AmSouth Fund. Similarly, the Board of Trustees of the Pioneer Fund, including its Independent Trustees, approved the Reorganization. They also determined that the Reorganization is in the best interests of the Pioneer Fund. The Trustees recommend that the shareholders of your AmSouth Fund vote FOR the proposal to approve the Agreement and Plan of Reorganization. 19 Appendix A Information about the underlying funds The following is intended to summarize the investment objectives and primary strategies of, and to provide you with certain other information about, the underlying funds. These summaries do not reflect all of the investment policies and strategies that are disclosed in each underlying fund's prospectus, and are not an offer of the underlying funds' shares. The underlying funds in which the funds intend to invest may change from time to time and the funds may invest in underlying funds in addition to those described below at the discretion of Pioneer without prior notice to or approval of shareholders. The prospectus and SAI for each underlying fund is available on the SEC's website as well as on our website at www.pioneerfunds.com. Each underlying fund normally will be invested according to its investment strategy. However, an underlying fund also may have the ability to invest without limitation in money market instruments or other investments for temporary, defensive purposes. The underlying funds that invest primarily in equity securities are: Pioneer Fund Investment objective Reasonable income and capital growth. Principal investment strategies The fund invests in a broad list of carefully selected, reasonably priced securities rather than in securities whose prices reflect a premium resulting from their current market popularity. The fund invests the major portion of its assets in equity securities, primarily of U.S. issuers.

(subadviser) The underlying funds that invest primarily in debt securities are: Pioneer Bond Fund Investment objective To provide current income from an investment grade portfolio with due regard to preservation of capital and prudent investment risk. The fund also seeks a relatively stable level of dividends; however, the level of dividends will be maintained only if consistent with preserving the investment grade quality of the fund's portfolio. Principal investment strategies The fund invests primarily in: o Debt securities issued or guaranteed by the U.S. government or its agencies and instrumentalities, o Debt securities, including convertible debt, of corporate and other issuers rated at least investment grade at the time of investment, and comparably rated commercial paper, 26 o Cash and cash equivalents, certificates of deposit, repurchase agreements maturing in one week or less and bankers' acceptances. Normally, the fund invests at least 80% of its total assets in these securities. In addition, the fund may invest up to 20% of its total assets in debt securities rated below investment grade or, if unrated, of equivalent quality as determined by Pioneer. Cash and cash equivalents include cash balances, accrued interest and receivables for items such as the proceeds, not yet received, from the sale of the fund's portfolio investments. Investment Adviser Pioneer Pioneer High Yield Fund Investment objective Maximize total return through a combination of income and capital appreciation. Principal investment strategies Normally, the fund invests at least 80% of its total assets in below investment grade (high yield) debt securities and preferred stocks. These high yield securities may be convertible into the equity securities of the issuer. 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 rated debt securities. Investment Adviser Pioneer Pioneer Short Term Income Fund Investment objective A high level of current income to the extent consistent with a relatively high level of stability of principal. Principal investment strategies The fund invests primarily in: o Debt securities issued or guaranteed by the U.S. government, its agencies or instrumentalities o Debt securities, including convertible debt, of corporate and other issuers and commercial paper o Mortgage-backed and asset-backed securities o Short-term money market instruments Normally, at least 80% of the fund's net assets are invested in debt securities that are rated investment grade at the time of purchase or cash and cash equivalents.

Investment Adviser Pioneer 27 Pioneer Cash Reserves Fund Investment objective High current income, preservation of capital and liquidity through investments in high-quality short-term securities. Principal investment strategies The fund seeks to maintain a constant net asset value of $1.00 per share by investing in high-quality, U.S. dollar denominated money market securities, including those issued by: o U.S. and foreign banks o U.S. and foreign corporate issuers o The U.S. government and its agencies and instrumentalities o Foreign governments o Multinational organizations such as the World Bank The fund may invest more than 25% of its total assets in U.S. government securities and obligations of U.S. banks. The fund may invest in any money market instrument that is a permissible investment for a money market fund under the rules of the Securities and Exchange Commission, including commercial paper, certificates of deposit, time deposits, bankers' acceptances, mortgage-backed and asset-backed securities, repurchase agreements, municipal obligations and other short-term debt securities. Investment Adviser Pioneer Pioneer Strategic Income Fund Investment objective A high level of current income. Principal investment strategies Normally, the fund invests at least 80% of its net assets (plus the amount of borrowings, if any, for investment purposes) in debt securities. The fund has the flexibility to invest in a broad range of issuers and segments of the debt securities markets. Pioneer Investment Management, Inc., the fund's investment adviser, allocates the fund's investments among the following three segments of the debt markets: o Below investment grade (high yield) securities of U.S. and non-U.S. issuers o Investment grade securities of U.S. issuers o Investment grade securities of non-U.S. issuers Pioneer's allocations among these segments of the debt markets depend upon its outlook for economic, interest rate and political trends. The fund invests primarily in: o Debt securities issued or guaranteed by the U.S. government, its agencies or instrumentalities or non-U.S. governmental entities 28 o Debt securities of U.S. and non-U.S. corporate issuers, including convertible debt o Mortgage-backed and asset-backed securities The fund's investments 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. The fund invests in securities with a broad range of maturities. Depending upon Pioneer's allocation among market segments, up to 70% of the fund's total assets may be in debt securities rated below investment grade at the time of purchase or determined to be of equivalent quality by Pioneer. Up to 20% of the fund's total assets may be invested in debt securities rated below CCC by Standard & Poor's Ratings Group or the equivalent by another 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 rated debt securities. As with all fixed income securities, the market values of convertible debt securities tend to decline as interest rates increase and, conversely, to increase as interest rates decline. However, when the market price of the common stock underlying a convertible security exceeds the conversion price, the convertible security tends to reflect the market price of the underlying common stock. Depending upon Pioneer's allocation among market segments, up to 85% of the fund's total assets may be in debt securities of non-U.S. corporate and governmental issuers, including debt securities of corporate and governmental issuers in emerging markets.

Comparison of Principal Risks of Investing in the Funds Because each Fund has a similar investment objective, primary investment policies and strategies, the Funds are subject to the same principal risks. You could lose money on your investment in either Fund 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 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 The adviser's judgment about the attractiveness, relative value or potential appreciation of a particular sector, security or investment strategy proves to be incorrect o To the extent that the Fund invests significantly in high yield securities, its exposure to the credit risks associated with such securities may be greater, its income and net asset value may be more volatile and it may be more difficult to achieve preservation of principal 8 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. To the extent a Fund invest significantly in mortgage-backed securities, its exposure to prepayment and extension risks may be greater than if it invested in other fixed income securities. At times, more than 25% of Pioneer Bond Fund's assets may be invested in the same market segment, such as financials. To the extent the Fund emphasizes 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. Past Performance Set forth below is performance information for each Fund. The bar charts show how each Fund's total return (not including any deduction for sales charges) has varied from year to year for each full calendar year. The table shows average annual total return (before and after 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 bar charts give an indication of the risks of investing in each Fund, including the fact that you could incur a loss and experience volatility of returns year to year. Past performance before and after taxes does not indicate future results.

After-tax returns are only shown for Class A shares and Class I shares and may vary for Class B shares. The Fund's after-tax returns are calculated using the highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. In certain cases, the figure representing "Return After Taxes on Distributions and Sale of Fund Shares" may be higher than the other return figures for the same period. A higher after-tax return results when a capital loss occurs upon redemption and translates into an assumed tax deduction that benefits the shareholder. Please note that actual after-tax returns depend on an investor's tax situation and may differ from those shown. Also note that 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.

(2) Sales charges may be reduced depending upon the amount invested or, in certain circumstances, waived. Class A shares of the Pioneer Fund bought as part of an investment of $1 million or more are not subject to an initial sales charge, but may be charged a CDSC of 1.00% if sold within one year of purchase. (3) For Class B shares purchased prior to the combination of AmSouth Funds with ISG Funds, the CDSC on such Class B shares held continuously declines over six years, starting with year one and ending in year seven from: 4%, 3%, 3%, 2%, 2%, 1%. For all other Class B shares held continuously, the CDSC declines over six years, starting with year one and ending in year seven from: 5%, 4%, 3%, 3%, 2%, 1%. Eight years after purchase (seven years in the case of shares acquired in the ISG combination), Class B shares automatically convert to Class A shares. (4) To discourage short-term trading, a redemption fee of 2.00% will be charged on sales or exchanges of Class A, Class B and Class I shares of your AmSouth Fund made within 7 days of the date of purchase. A wire transfer fee of $7.00 will be deducted from the amount of your redemption if you request a wire transfer. (5) Other expenses for your AmSouth Fund are being limited to 0.49% for Class A shares, 0.50% for Class B shares and 0.35% for Class I shares. Any fee waiver or expense reimbursement arrangement is voluntary and may be discontinued at any time. (6) The Pioneer Fund's total annual operating expenses in the table have not been reduced by any expense offset arrangements. (7) The expenses in the table above reflect the expense limitation in effect through November 1, 2007, under which Pioneer has contractually agreed to limit ordinary operating expenses to the extent required to reduce Class A expenses to 1.00% of the average daily net assets attributable to Class A shares. There can be no assurance that Pioneer will extend the expense limitation beyond November 1, 2007. (8) The expenses in the table above reflect the expense limitation in effect through November 1, 2006, under which Pioneer has contractually agreed to limit ordinary operating expenses to the extent required to reduce Class B expenses to 1.90% of the average daily net assets attributable to Class B shares. There can be no assurance that Pioneer will extend the expense limitation beyond November 1, 2006. 12 The hypothetical example below helps you compare the cost of investing in each Fund. It assumes that: (a) you invest $10,000 in each Fund for the time periods shown, (b) you reinvest all dividends and distributions, (c) your investment has a 5% return each year, (d) each Fund's gross operating expenses remain the same, and (e) the expense limitation for your Fund is in effect for year one.

The Trustees considered the following matters, among others, in approving the proposal. First, AAMI, the investment adviser to your AmSouth Fund, informed the Trustees that it does not intend to continue to provide investment advisory services to the AmSouth Funds. Consequently, a change in your Fund's investment adviser was necessary. In the absence of the Reorganization, such a change would be more likely to motivate shareholders invested in reliance on AAMI's role to withdraw from the Fund, thereby reducing fund size and increasing fund expense ratios. Second, the historical investment performance of Pioneer Bond Fund is comparable to your AmSouth Fund's investment performance. For the one, five and ten year periods ended December 31, 2004, Class A shares of Pioneer Bond Fund had an average annual return of 0.95% (one year); 6.86% (five year); and 6.69% (ten year), compared to an average annual return of the Class A shares of your AmSouth Fund of -1.45% (one year); 6.14% (five year); and 7.64% (ten year), respectively, during the same period. The Trustees also noted that, for the one and five year periods ended March 31, 2005, Class A shares of Pioneer Bond Fund had an average annual return of 2.67% (one year); and 7.60% (five year), compared to an average annual return of the Class A shares of your AmSouth Fund of -0.25% (one year); and 6.25% (five year), during the same period. In addition, the Trustees considered the track record of Pioneer in managing equity and fixed income mutual funds. Third, the resources of Pioneer. At December 31, 2004, Pioneer managed over 80 investment companies and accounts with approximately $42 billion in assets, including $15.7 billion in fixed income searches. Pioneer is part of the global asset management group of UniCredito Italiano S.p.A., one of the largest banking groups in Italy, providing investment management and financial services to mutual funds, institutional and other clients. As of December 31, 2004, assets under management of 13 UniCredito Italiano S.p.A. were approximately $175 billion worldwide. Shareholders of your AmSouth Fund would become part of a significantly larger family of funds that offers a more diverse array of investment options and enhanced shareholder account options. The Pioneer family of mutual funds offers over 80 funds, including domestic and international equity and fixed income funds and a money market fund that will be available to your AmSouth Fund's shareholders through exchanges. Fourth, the aggregate management and administration fees incurred by your AmSouth Fund are higher than the management fee paid by Pioneer Bond Fund. The aggregate Rule 12b-1 distribution and shareholder servicing fees and non-Rule 12b-1 shareholder servicing fees paid by the Class A and Class B shares of both Funds are the same. Moreover, your AmSouth Fund's Class I shares pay a non 12b-1 shareholder servicing fee that is not paid by the Pioneer Fund's Class Y shares. With respect to Class I shares, both the gross and net expenses of the Pioneer Fund are lower than your AmSouth Fund. While the pro forma expenses are estimated to be lower for your Class A and B Shares on a gross basis, the expenses will be higher on a net basis. The lower net expenses of your AmSouth Fund are a result of voluntary expense limitations that may be discontinued at any time. The trustees considered the positive factors associated with the Reorganization, such as greater fund assets and potential for growth, to outweigh the negative factors, such as the increase in expenses. Fifth, the Class A, B and Y shares of Pioneer Bond Fund received in the Reorganization will provide AmSouth High Quality Bond Fund shareholders with exposure to substantially the same investment product as they currently have. Sixth, the transaction is structured to qualify as a tax-free reorganization under Section 368(a) of the Internal Revenue Code of 1986 and therefore will not be treated as a taxable sale of your AmSouth shares. Pioneer and AmSouth Bank will pay all costs of preparing and printing the Funds' proxy statements and solicitation costs incurred by the Funds in connection with the Reorganization. AAMI will otherwise be responsible for all costs and expenses of your Fund in connection with the Reorganization. The Trustees also considered that Pioneer and AmSouth Bank will benefit from the Reorganization. See "Will Pioneer and AmSouth Bank Benefit from the Reorganizations." The Board of Trustees of the Pioneer Fund also considered that the Reorganization presents an excellent opportunity for the Pioneer Fund to acquire investment assets 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 the Pioneer Fund and its shareholders. CAPITALIZATION The following table sets forth the capitalization of each Fund as of May 31, 2005, and the pro forma combined Fund as of May 31, 2005.

The table should not be relied upon to determine the amount of the Pioneer Fund's shares that will actually be received and distributed. BOARD'S EVALUATION AND RECOMMENDATION For the reasons described above, the Trustees, including the Independent Trustees, approved the Reorganization. In particular, the Trustees determined that the Reorganization is in the best interests of your AmSouth Fund. Similarly, the Board of Trustees of the Pioneer Fund, including its Independent Trustees, approved the Reorganization. They also determined that the Reorganization is in the best interests of the Pioneer Fund. The Trustees recommend that the shareholders of your AmSouth Fund vote FOR the proposal to approve the Agreement and Plan of Reorganization. 15 AmSouth Florida Tax-Exempt Fund and Pioneer Florida Tax Free Income Fund PROPOSAL 1(o) Approval of Agreement and Plan of Reorganization 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-2, because it contains details that are not in the summary.

The Fund will have a dollar-weighted average maturity of five to ten years. The Fund may invest in municipal securities of any maturity. Municipal securities with longer maturities are generally more volatile than other fixed income securities with shorter maturities.

The Fund may invest up to 20% of its net assets in securities of other investment companies, investment grade commercial paper, U.S. government securities, U.S. or foreign bank instruments and repurchase agreements. The 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.

For example, gas, gas transmission, electric and gas, electric, and telephone will each be considered a separate industry.

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. 5 AmSouth Florida Tax-Exempt Fund Pioneer Florida Tax Free Income Fund - ---------------------------------------------------------------------------------------------------------------------------- Short-term trading The Fund may engage in the technique of The Fund usually does not trade for short-term short-term trading. Such trading involves the profits. The Fund will sell an investment, selling of securities held for a short time, however, even if it has only been held for a ranging from several months to less than a short time, if it no longer meets the Fund's day. The object of such short-term trading is investment criteria. to increase the potential for capital appreciation and/or income of the Fund in order to take advantage of what AAMI believes are changes in market, industry or individual company conditions or outlook. Any such trading would increase the turnover rate of a Fund and its transaction costs. Other investment policies As described above, the Funds have substantially similar principal investment strategies and and restrictions policies. Certain of the non-principal investment policies and restrictions are different.

Comparison of Principal Risks of Investing in the Funds Because each Fund has a similar investment objective, primary investment policies and strategies, the Funds are subject to the same principal risks. Even though the Funds seek current income exempt from federal and Florida intangible personal property tax, 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 Because the 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 o The adviser is incorrect in its expectation of changes in interest rates or the credit quality of an issuer Although distributions of interest income from the Fund's tax-exempt securities are generally exempt from regular federal income tax and Florida intangible personal property tax, distributions from other sources, including capital gain distributions and any gains on the sale of your shares, are not. You should consult a tax adviser about state and local taxes on your Fund distributions. At times, more than 25% of the Fund's assets may be invested in the same market segment, such as financials. To the extent the Fund emphasizes 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. 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. Past Performance Set forth below is performance information for AmSouth Florida Tax-Exempt Fund. The bar charts show how AmSouth Florida Tax-Exempt Fund's total return (not including any deduction for sales charges) has varied from year to year for each full calendar year. The tables show average annual total return for AmSouth Florida Tax-Exempt Fund over time for each class of shares compared with a broad-based securities market index. The bar charts give an indication of the risks of investing in AmSouth Florida Tax-Exempt Fund, including the fact that you could incur a loss and experience volatility of returns year to year.

The table above shows the impact of taxes on the AmSouth Florida Tax-Exempt Fund's returns. The Fund's after-tax returns are calculated using the highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. In certain cases, the figure representing "Return After Taxes on Distributions and Sale of Fund Shares" may be higher than the other return figures for the same period. A higher after-tax return results when a capital loss occurs upon redemption and translates into an assumed tax deduction that benefits the shareholder. Please note that actual after-tax returns depend on an investor's tax situation and may differ from those shown. Also note that after-tax returns shown 10 are not relevant to investors who hold their Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

(3) For Class B shares purchased prior to the combination of AmSouth Funds with ISG Funds, the CDSC on such Class B shares held continuously declines over six years, starting with year one and ending in year seven from: 4%, 3%, 3%, 2%, 2%, 1%. For all other Class B shares held continuously, the CDSC declines over six years, starting with year one and ending in year seven from: 5%, 4%, 3%, 3%, 2%, 1%. Eight years after purchase (seven years in the case of shares acquired in the ISG combination), Class B shares automatically convert to Class A shares. (4) To discourage short-term trading, a redemption fee of 2.00% will be charged on sales or exchanges of Class A, Class B and Class I shares of your AmSouth Fund made within 7 days of the date of purchase. A wire transfer fee of $7.00 will be deducted from the amount of your redemption if you request a wire transfer. (5) Other expenses for the AmSouth Fund are being limited to 0.33% for Class A shares, 0.33% for Class B shares and 0.18% for Class I shares. Any fee waiver or expense reimbursement arrangement is voluntary and may be discontinued at any time. (6) The Pioneer Fund's total annual operating expenses have not been reduced by any expense offset arrangements. The hypothetical example below helps you compare the cost of investing in each Fund. It assumes that: (a) you invest $10,000 in each Fund for the time periods shown, (b) you reinvest all dividends and distributions, (c) your investment has a 5% return each year, and (d) each Fund's gross operating expenses remain the same. The examples are for comparison purposes only and are not a representation of either Fund's actual expenses or returns, either past or future.

The Trustees considered the following matters, among others, in approving the proposal. First, AAMI, the investment adviser to your Amsouth Fund, informed the Trustees that it does not intend to continue to provide investment advisory services to the AmSouth Funds. Consequently, a change in your AmSouth Fund's investment adviser was necessary. . In the absence of the Reorganization, such a change would be more likely to motivate shareholders invested in reliance on AAMI's role to withdraw from the Fund, thereby reducing fund size and increasing fund expense ratios. Second, the resources of Pioneer. At December 31, 2004, Pioneer managed over 80 investment companies and accounts with approximately $42 billion in assets, including $2 billion in municipal securities. Pioneer is part of the global asset management group of UniCredito Italiano S.p.A., one of the largest banking groups in Italy, providing investment management and financial services to mutual funds, institutional and other clients. As of December 31, 2004, assets under management of UniCredito Italiano S.p.A. were approximately $175 billion worldwide. Shareholders of your AmSouth Fund would become part of a significantly larger family of funds that offers a more diverse array of investment options and enhanced shareholder account options. The Pioneer family of mutual funds offers over 80 funds, including domestic and international equity and fixed income funds and a money market fund that will be available to your AmSouth Fund's shareholders through exchanges. Third, Pioneer Florida Tax Free Income Fund's management fee (0.50% of 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) will be the same as or lower than the advisory fee of your Fund (0.50% of average daily net assets). The estimated pro forma expenses on a total basis of the Pioneer Fund after giving effect to the Reorganizations are expected to decline for all classes of shares. The estimated pro forma expenses on a net basis are also expected to decline for Class A shares. Although the estimated pro forma operating expenses for the AmSouth Fund's Class B and I shares are lower on a gross basis, the expenses are higher on a net basis. AmSouth Bank and its affiliates have informed the trustees that they will discontinue their expense limitations in the future. The trustees considered the positive factors associated with the reorganization to outweigh the negative factors, such as the increase in expenses. The aggregate Rule 12b-1 distribution and shareholder servicing fees and non-Rule 12b-1 shareholder servicing fees paid by the Class A and Class B shares of both Funds will be the same. Moreover, your AmSouth Fund's Class I shares pay a non 12b-1 shareholder servicing fee that will not be paid by the Pioneer Fund's Class Y shares. In addition, the broader distribution arrangements of the Pioneer Fund offer greater potential for further asset growth and reduce per share expenses. Fourth, the Class A, B and Y shares of Pioneer Florida Tax Free Income Fund received in the Reorganization will provide AmSouth Florida Tax-Exempt Fund shareholders with exposure to substantially the same investment product as they currently have. Fifth, the transaction is structured to qualify as a tax-free reorganization under Section 368(a) of the Internal Revenue Code of 1986 and therefore will not be treated as a taxable sale of your AmSouth shares. Pioneer and AmSouth Bank will pay all costs of preparing and printing the Funds' proxy statements and solicitation costs incurred by the Funds in connection with the Reorganization. AAMI will otherwise be responsible for all costs and expenses of AmSouth Florida Tax-Exempt Fund in connection with the Reorganization. The Trustees also considered that Pioneer and AmSouth Bank will benefit from the Reorganization. See "Will Pioneer and AmSouth Bank Benefit from the Reorganizations." The Board of Trustees of the Pioneer Fund also considered that the Reorganization presents an excellent opportunity for the Pioneer Fund to acquire investment assets 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 the Pioneer Fund and its shareholders. 13 CAPITALIZATION The following table sets forth the capitalization of each Fund as of May 31, 2005, and the pro forma combined Fund as of May 31, 2005. The table also sets forth the pro forma capitalization of the combined Fund as of May 31, 2005, assuming the shareholders of AmSouth Florida Tax-Exempt Fund approve the reorganization of their Fund into Pioneer Florida Tax Free Income Fund. Pro Forma AmSouth Florida Tax- Pioneer Florida Tax Free Pioneer Florida Tax Free Exempt Fund Income Fund Income Fund May 31, 2005 May 31, 2005 May 31, 2005 -------------------- ------------------------ ------------------------ Total Net Assets (in thousands) $ 52,512 N/A $ 52,512 Class A shares ............. $ 4,230 N/A $ 4,230 Class B shares ............. $ 2,473 N/A $ 2,473 Class I/Y shares ........... $ 45,809 N/A $ 45,809 Net Asset Value Per Share Class A shares ............. $ 10.59 N/A $ 10.59 Class B shares ............. $ 10.56 N/A $ 10.56 Class I/Y shares ........... $ 10.60 N/A $ 10.60 Shares Outstanding Class A shares ............. 399,350 N/A 399,350 Class B shares ............. 234,108 N/A 234,108 Class I/Y shares ........... 4,321,999 N/A 4,321,999 It is impossible to predict how many shares of the Pioneer Fund will actually be received and distributed by your AmSouth Fund on the Reorganization date. The table should not be relied upon to determine the amount of the Pioneer Fund's shares that will actually be received and distributed. BOARD'S EVALUATION AND RECOMMENDATION For the reasons described above, the Trustees, including the Independent Trustees, approved the Reorganization. In particular, the Trustees determined that the Reorganization is in the best interests of your AmSouth Fund. Similarly, the Board of Trustees of the Pioneer Fund, including its Independent Trustees, approved the Reorganization. They also determined that the Reorganization is in the best interests of the Pioneer Fund. The Trustees recommend that the shareholders of your AmSouth Fund vote FOR the proposal to approve the Agreement and Plan of Reorganization. 14 AmSouth High Quality Municipal Bond Fund and Pioneer Tax Free Income Fund PROPOSAL 1(p) Approval of Agreement and Plan of Reorganization 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-1, because it contains details that are not in the summary. Each Fund invests in securities that are exempt from regular federal income tax and, consequently, the Funds have similar investment policies and risks. In the table below, if a row extends across the entire table, the policy disclosed applies to both your AmSouth Fund and the Pioneer Fund.

The Fund will have a dollar-weighted average maturity of five to ten years. Investment strategies AAMI's fixed income portfolio management Pioneer considers both broad economic factors process focuses on the four key areas of and issuer-specific factors in selecting a duration management, sector weights, position portfolio designed to achieve the Fund's on the yield curve and security selection; investment objective. In assessing the AAMI's goal is to add value in each of these appropriate maturity and rating weighting of four areas through the active management of the the Fund's portfolio, Pioneer considers a Fund's portfolio. Beginning with rigorous variety of factors that are expected to fundamental analysis of the economy and taking influence economic activity and interest into account characteristics of the current rates. These factors include fundamental business and interest rate cycles, AAMI arrives economic indicators, such as the rates of at a projection of the likely trend in interest economic growth and inflation, Federal rates and adjusts duration accordingly. Reserve monetary policy and the relative Analysis of the shape of the yield curve and value of the U.S. dollar compared to other yield spreads among bond market sectors leads currencies. Once Pioneer determines the to further refinements in strategy. 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 who have access to a wide variety of research.

Your exchange request must be for at charges. You must meet the minimum investment least $1,000.

Exchanges from one Fund to another charging you either an initial or contingent are taxable. Class A shares may be exchanged deferred shares charge at the time of the for Class I shares of the same Fund or another exchange.

The Fund uses a "first-in, first-out" method to determine how long you have held your shares. This means that if you purchased shares on different days, the shares purchased first will be considered redeemed first for purposes of determining whether the redemption fee will be charged. The fee will be charged on all covered 7 AmSouth High Quality Municipal Bond Fund Pioneer Tax Free Income Fund - ---------------------------------------------------------------------------------------------------------------------------- redemptions and exchanges, including those made through retirement plan, brokerage and other types of omnibus accounts (except where it is not practical for the plan administrator or brokerage firm to implement the fee). The Fund will not impose the redemption fee on a redemption or exchange of shares purchased upon the reinvestment of dividend and capital gain distributions. Selling shares Shares of each Fund are sold at the net asset value per share next calculated after the Fund receives your request in good order.

You can also contacting a financial intermediary as sell your shares by contacting the Fund described in the Fund's prospectus. directly if your account is registered in your name. If the account is established in the shareholder's own name, shareholders may also redeem shares of the Pioneer Fund by telephone or online. Comparison of Principal Risks of Investing in the Funds Because each Fund has a similar investment objective, primary investment policies and strategies, the Funds are subject to the same principal risks. You could lose money on your investment in either Fund 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 To the extent the Fund concentrates its investments in a single state or securities the payments on which are dependent upon a single industry, the Fund will be more susceptible to risks associated with that state or industry o The adviser is incorrect in its expectation of changes in interest rates or the credit quality of an issuer In addition, at times, more than 25% of Pioneer Tax Free Income Fund's assets may be invested in the same market segment, such as financials or technology. To the extent the Fund emphasizes 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. Pioneer Tax Free Income Fund may also invest up to 10% of its net assets in debt securities rated below investment grade or, if unrated, of equivalent quality as determined by Pioneer. Debt securities rated below investment grade are 8 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. AmSouth High Quality Municipal Bond Fund may invest 25% or more of its total assets in bonds, notes and warrants generally issued by or on behalf of the State of Alabama and its political subdivisions, the interest on which, in the opinion of the issuer's bond counsel at the time of issuance, is exempt from both federal income tax and Alabama personal income tax and is not treated as a preference item for purposes of the federal alternative minimum tax. By concentrating its investments in securities issued by Alabama and its municipalities, the Fund will be more vulnerable to unfavorable developments in Alabama than funds that are more geographically diversified. Additionally, because of the relatively small number of issuers of Alabama municipal securities, the Fund is likely to invest in a limited number of issuers. Past Performance Set forth below is performance information for each Fund. The bar charts show how each Fund's total return (not including any deduction for sales charges) has varied from year to year for each full calendar year. The tables show average annual total return (before and after 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 bar charts give an indication of the risks of investing in each Fund, including the fact that you could incur a loss and experience volatility of returns year to year. Past performance before and after taxes does not indicate future results.

The quoted before-tax returns of the Fund includes the performance of the commingled accounts for periods dating back to 7/31/93, and prior to the Fund's commencement of operations, restated to reflect the expenses associated with the Fund. The commingled accounts were not registered with the SEC and, therefore, were not subject to the investment restrictions imposed by law on registered mutual funds. If the commingled accounts had been registered, their performance may have been adversely affected. After-tax returns reflect performance since 7/1/97, and do not include the performance of the commingled accounts prior to that date. Class A shares were first offered on 7/1/97. (2) Performance for the Class B shares, which were first offered on 2/3/99, is based on the historical performance of the Fund's Class A shares, including the performance of the commingled accounts (without sales charge) prior to that date. The commingled accounts were managed using substantially the same investment objective, policies and methodologies as the Fund. The historical performance of the Class B shares has been restated to reflect the Fund's Class B shares distribution (12b-1) fees and the contingent deferred sales charge. (3) Performance for the Class I shares, which were first offered on 9/2/97, is based on the historical performance of the Fund's Class A shares, including the performance of the commingled accounts (without sales charge) prior to that date. The commingled accounts were managed using substantially the same investment objective, policies and methodologies as the Fund. 10 (4) Merrill Lynch 1-12 Year Municipal Bond Index, an unmanaged index generally representative of municipal bonds with intermediate maturities of no less than one year and no more than twelve years, is for reference only, does not mirror the Fund's investments, and reflects no deduction for fees, expenses or taxes. The table above shows the impact of taxes on the AmSouth High Quality Municipal Bond Fund's returns. The Fund's after-tax returns are calculated using the highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. In certain cases, the figure representing "Return After Taxes on Distributions and Sale of Fund Shares" may be higher than the other return figures for the same period. A higher after-tax return results when a capital loss occurs upon redemption and translates into an assumed tax deduction that benefits the shareholder. Please note that actual after-tax returns depend on an investor's tax situation and may differ from those shown. Also note that after-tax returns shown are not relevant to investors who hold their Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

(2) Sales charges may be reduced depending upon the amount invested or, in certain circumstances, waived. Class A shares of the Pioneer Fund bought as part of an investment of $1 million or more are not subject to an initial sales charge, but may be charged a CDSC of 1.00% if sold within one year of purchase. (3) For Class B shares purchased prior to the combination of AmSouth Funds with ISG Funds, the CDSC on such Class B shares held continuously declines over six years, starting with year one and ending in year seven from: 4%, 3%, 3%, 2%, 2%, 1%. For all other Class B shares held continuously, the CDSC declines over six years, starting with year one and ending in year seven from: 5%, 4%, 3%, 3%, 2%, 1%. Eight years after purchase (seven years in the case of shares acquired in the ISG combination), Class B shares automatically convert to Class A shares (4) To discourage short-term trading, a redemption fee of 2.00% will be charged on sales or exchanges of Class A, Class B and Class I shares of your AmSouth Fund made within 7 days of the date of purchase. A wire transfer fee of $7.00 will be deducted from the amount of your redemption if you request a wire transfer. (5) Other expenses for your AmSouth Fund are being limited to 0.38% for Class A shares, 0.38% for Class B shares and 0.23% for Class I shares. Any fee waiver or expense reimbursement arrangement is voluntary and may be discontinued at any time. (6) The Pioneer Fund's total annual operating expenses in the table have not been reduced by any expense offset arrangements. 13 The hypothetical example below helps you compare the cost of investing in each Fund. It assumes that: (a) you invest $10,000 in each Fund for the time periods shown, (b) you reinvest all dividends and distributions, (c) your investment has a 5% return each year, (d) and each Fund's gross operating expenses remain the same. The examples are for comparison purposes only and are not a representation of either Fund's actual expenses or returns, either past or future.

The Trustees considered the following matters, among others, in approving the proposal. First, AAMI, the investment adviser to your AmSouth Fund, informed the Trustees that it does not intend to continue to provide investment advisory services to the AmSouth Funds. Consequently, a change in your AmSouth Fund's investment adviser was necessary. In the absence of the Reorganization, such a change would be more likely to motivate shareholders invested in reliance on AAMI's role to withdraw from the Fund, thereby reducing fund size and increasing fund expense ratios. Second, after the Reorganization, the combined Fund will have an asset size substantially larger than that of your AmSouth Fund, which may allow the combined Fund to achieve significant economies of scale in investments or expenses. Third, the historical investment performance of Pioneer Tax Free Income Fund is better than your AmSouth Fund's investment performance. For the one, five and ten year periods ended December 31, 2004, Class A shares of Pioneer Tax Free Income Fund had an average annual return of 0.05% (one year); 5.66% (five year); and 5.88% (ten year) compared to an average annual return of the Class A shares of your AmSouth Fund of -2.55% (one year); 4.42% (five year); and 4.55% (ten year), respectively, during the same period. The trustees also considered performance information provided for the one, three, and five year periods ended March 31, 2005 during which Class A shares of Pioneer Tax Free Income Fund had an average annual return of 3.30% (one year); 5.82% (three year); and 6.10% (five year), compared to an average annual return of the 14 Class A shares of your AmSouth Fund of -0.76% (one year); 3.73% (three year); and 4.64% (five year), respectively, during the same period. In addition, the Trustees considered the track record of Pioneer in managing equity and fixed income mutual funds. Fourth, the resources of Pioneer. At December 31, 2004, Pioneer managed over 80 investment companies and accounts with approximately $42 billion in assets. Pioneer is part of the global asset management group of UniCredito Italiano S.p.A., one of the largest banking groups in Italy, providing investment management and financial services to mutual funds, institutional and other clients. As of December 31, 2004, assets under management of UniCredito Italiano S.p.A. were approximately $175 billion worldwide. Shareholders of your AmSouth Fund would become part of a significantly larger family of funds that offers a more diverse array of investment options and enhanced shareholder account options. The Pioneer family of mutual funds offers over 80 funds, including domestic and international equity and fixed income funds and a money market fund that will be available to your AmSouth Fund's shareholders through exchanges. Fifth, Pioneer Tax Free Income Fund's management fee will benefit from breakpoints as assets increase as a result of the Reorganization. The aggregate Rule 12b-1 distribution and shareholder servicing fees and non-Rule 12b-1 shareholder servicing fees paid by the Class A and Class B shares of both Funds are the same. Moreover, your AmSouth Fund's Class I shares pay a non 12b-1 shareholder servicing fee that is not paid by the Pioneer Fund's Class Y shares. Although your AmSouth Fund's expenses attributable to Class A and Class B shares net of limitations are lower than the Pioneer Fund's net expenses currently and on a pro forma basis, your AmSouth Fund may terminate such limitations at any time. AAMI has informed the trustees that the expense waivers will be discontinued in the future. The trustees considered the positive factors associated with the Reorganization, such as superior performance of the Pioneer Fund, greater fund assets and potential for growth, to outweigh the negative factors. The gross expenses of Pioneer Fund's Class A, Class B and Class Y shares are lower than the AmSouth Fund's gross expenses attributable to Class A, Class B and Class I shares and are estimated to be lower on a pro forma basis after giving effect to the Reorgnization. In addition, the net expenses of the Class Y shares of the Pioneer Fund are lower than the net expenses of the AmSouth Fund attributable to Class I shares and are estimated to be lower on a pro forma basis. In addition, the broader distribution arrangement of the Pioneer Fund offers greater potential for further increases in net assets of the combined fund and lower per share expense ratios. Sixth, the Class A, B and Y shares of Pioneer Tax Free Income Fund received in the Reorganization will provide AmSouth High Quality Municipal Bond Fund shareholders with exposure to substantially the same investment product as they currently have. Seventh, the transaction is structured to qualify as a tax-free reorganization under Section 368(a) of the Internal Revenue Code of 1986 and therefore will not be treated as a taxable sale of your AmSouth shares. Pioneer and AmSouth Bank will pay all costs of preparing and printing the Funds' proxy statements and solicitation costs incurred by the Funds in connection with the Reorganization. AAMI will otherwise be responsible for all costs and expenses of AmSouth High Quality Municipal Bond Fund in connection with the Reorganization. The Trustees also considered that Pioneer and AmSouth Bank will benefit from the Reorganization. See "Will Pioneer and AmSouth Bank Benefit from the Reorganizations." The Board of Trustees of the Pioneer Fund also considered that the Reorganization presents an excellent opportunity for the Pioneer Fund to acquire investment assets 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 the Pioneer Fund and its shareholders. 15 CAPITALIZATION The following table sets forth the capitalization of each Fund as of May 31, 2005, and the pro forma combined Fund as of May 31, 2005. The table also sets forth the pro forma capitalization of the combined Fund as of May 31, 2005, assuming the shareholders of AmSouth Tennessee Tax-Exempt Bond Fund approve the reorganization of their fund into Pioneer Tax Free Income Fund.

The table should not be relied upon to determine the amount of the Pioneer Fund's shares that will actually be received and distributed. BOARD'S EVALUATION AND RECOMMENDATION For the reasons described above, the Trustees, including the Independent Trustees, approved the Reorganization. In particular, the Trustees determined that the Reorganization is in the best interests of your AmSouth Fund. Similarly, the Board of Trustees of the Pioneer Fund, including its Independent Trustees, approved the Reorganization. They also determined that the Reorganization is in the best interests of the Pioneer Fund. The Trustees recommend that the shareholders of your AmSouth Fund vote FOR the proposal to approve the Agreement and Plan of Reorganization. 16 AmSouth Tennessee Tax-Exempt Fund and Pioneer Tax Free Income Fund PROPOSAL 1(q) Approval of Agreement and Plan of Reorganization SUMMARY The following is a summary of more complete information appearing later in this Proxy Statement/Prospectus or incorporated herein.

In making these portfolio decisions, Pioneer relies on the knowledge, experience and judgment of its staff who have access to a wide variety of research.

If the account is established in the shareholder's own name, shareholders may also redeem shares of the Fund by telephone or online. Comparison of Principal Risks of Investing in the Funds Because each Fund primarily invests in municipal securities, the Funds are subject to the same principal risks. You could lose money on your investment in either Fund 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 To the extent the Pioneer Fund concentrates its investments in a single state or securities the payments on which are dependent upon a single industry, the Fund will be more susceptible to risks associated with that state or industry. By concentrating its investments in securities issued by Tennessee and its municipalities, AmSouth Tennessee Tax-Exempt Fund will be more vulnerable to unfavorable developments in Tennessee than funds that are more geographically diversified. o The adviser is incorrect in its expectation of changes in interest rates or the credit quality of an issuer In addition, at times, more than 25% of Pioneer Tax Free Income Fund's assets may be invested in the same market segment, such as financials or technology. To the extent the Fund emphasizes 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. Pioneer Tax Free Income Fund may also invest up to 10% of its net assets in debt securities rated below investment grade 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. AmSouth Tennessee Tax-Exempt Fund is subject to risks relating to the fact that it is non-diversified. The Fund may invest in a small number of companies which may increase the volatility of the Fund. Accordingly, the Fund's portfolio may be more sensitive to changes in the market value of a single company or industry. 8 Past Performance Set forth below is performance information for each Fund. The bar charts show how each Fund's total return (not including any deduction for sales charges) has varied from year to year for each full calendar year. The tables show average annual total return (before and after 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 bar charts give an indication of the risks of investing in each Fund, including the fact that you could incur a loss and experience volatility of returns year to year. Past performance before and after taxes does not indicate future results.

The ISG Tennessee Tax-Exempt Fund, commenced operations on 3/28/94, through a transfer of assets from certain collective trust fund ("commingled") accounts managed by First American National Bank, using substantially the same investment objective, policies and methodologies as the Fund. The quoted before-tax returns of the Fund includes the performance of the predecessor fund commingled accounts for periods dating back to 7/31/93, and prior to the Fund's commencement of operations, restated to reflect the expenses associated with the Fund. The commingled accounts were not registered with the SEC and, therefore, were not subject to the investment restrictions imposed by law on registered mutual funds. If the commingled accounts had been registered, their performance may have been adversely affected. After-tax returns reflect performance since 4/1/96, and do not include the performance of the commingled accounts prior to that date. Class A Shares were first offered on 3/28/94. (2) Performance for the Class B Shares, which were first offered on 2/24/98, is based on the historical performance of the Fund's Class A Shares, including the performance of the predecessor fund and commingled accounts (without sales charge) prior to that date. The predecessor fund and commingled accounts were managed using substantially the same investment objective, policies and methodologies as the Fund. The historical performance of the Class B Shares has been restated to reflect the Fund's Class B Shares distribution (12b-1) fees and the contingent deferred sales charge. (3) Performance for the Class I Shares, which were first offered on 10/3/97, is based on the historical performance of the Fund's Class A Shares, including the performance of the predecessor fund and commingled accounts (without sales charge) prior to that date. The predecessor fund and commingled accounts were managed using substantially the same investment objective, policies and methodologies as the Fund. (4) Merrill Lynch 1-12 Year Municipal Bond Index, an unmanaged index generally representative of municipal bonds with intermediate maturities of no less than one year and no more than twelve years. The Index is for reference only, does not mirror the Fund's investments, and reflects no deduction for fees, expenses or taxes. The table shows the impact of taxes on the Fund's returns. The Fund's after-tax returns are calculated using the highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. In certain cases, the figure representing "Return After Taxes on Distributions and Sale of Fund Shares" may be higher than the other return figures for the same period. A higher after-tax return results when a capital loss occurs upon redemption and translates into an assumed tax deduction that benefits the shareholder. Please note that actual after-tax returns depend on an investor's tax situation and may differ from those shown. Also note that after-tax returns shown are not relevant to investors who hold their Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts. 10 Pioneer Tax Free Income Fund Average Annual Total Returns as of December 31, 2004 1 Year 5 Years 10 Years - --------------------------------------------------------------------------------------------------------------- Pioneer Tax Free Income Fund, Class A shares - --------------------------------------------------------------------------------------------------------------- Return Before Taxes 0.05% 5.66% 5.88% - --------------------------------------------------------------------------------------------------------------- Return After Taxes on Distributions 0.05% 5.56% 5.65% - --------------------------------------------------------------------------------------------------------------- Return After Taxes on Distributions and Sale of Fund Shares 1.69% 5.52% 5.66% - --------------------------------------------------------------------------------------------------------------- Pioneer Tax Free Income Fund, Class B shares - --------------------------------------------------------------------------------------------------------------- Return Before Taxes 0.07% 5.84% N/A - --------------------------------------------------------------------------------------------------------------- Pioneer Tax Free Income Fund, Class Y shares(1) - --------------------------------------------------------------------------------------------------------------- Return Before Taxes 5.14% 6.26% 6.14% - --------------------------------------------------------------------------------------------------------------- Return After Taxes on Distributions 5.14% 6.16% 5.91% - --------------------------------------------------------------------------------------------------------------- Return After Taxes on Distributions and Sale of Fund Shares 5.21% 6.02% 5.88% - --------------------------------------------------------------------------------------------------------------- Lehman Brothers Municipal Bond Index(2) 4.48% 7.20% 7.06% (reflects no deduction for fees, expenses or taxes) - --------------------------------------------------------------------------------------------------------------- (1) Reflects the inception of the Fund's Class A shares.

(3) For Class B shares purchased prior to the combination of AmSouth Funds with ISG Funds, the CDSC on such Class B Shares held continuously declines over six years, starting with year one and ending in year seven from: 4%, 3%, 3%, 2%, 2%, 1%. For all other Class B shares held continuously, the CDSC declines over six years, starting with year one and ending in year seven from: 5%, 4%, 3%, 3%, 2%, 1%. Eight years after purchase (seven years in the case of shares acquired in the ISG combination), Class B shares automatically convert to Class A shares. (4) To discourage short-term trading, a redemption fee of 2.00% will be charged on sales or exchanges of Class A, Class B and Class I shares of your AmSouth Fund made within 7 days of the date of purchase. A wire transfer fee of $7.00 will be deducted from the amount of your redemption if you request a wire transfer. (5) Other expenses for the AmSouth Fund are being limited to 0.50% for Class A shares, 050% for Class B shares and 0.35% for Class I shares. Any fee waiver or expense reimbursement arrangement is voluntary and may be discontinued at any time. (6) The Pioneer Fund's total annual operating expenses in the table have not been reduced by any expense offset arrangements. 13 The hypothetical example below helps you compare the cost of investing in each Fund. It assumes that: (a) you invest $10,000 in each Fund for the time periods shown, (b) you reinvest all dividends and distributions, (c) your investment has a 5% return each year, and (d) each Fund's gross operating expenses remain the same. The examples are for comparison purposes only and are not a representation of either Fund's actual expenses or returns, either past or future.

The Trustees considered the following matters, among others, in approving the proposal. First, AAMI, the investment adviser to your AmSouth Fund informed the Trustees that it does not intend to continue to provide investment advisory services to the AmSouth Funds. Consequently, a change in your AmSouth Fund's investment adviser was necessary. In the absence of the Reorganization, such a change would be more likely to motivate shareholders invested in reliance on AAMI's role to withdraw from the Fund, thereby reducing fund size and increasing fund expense ratios. Second, after the Reorganization, the combined Fund will have an asset size substantially larger than that of your AmSouth Fund, which may allow the combined Fund to achieve significant economies of scale in investments or expenses. Third, the historical investment performance of Pioneer Tax Free Income Fund is better than your AmSouth Fund's investment performance. For the one, five and ten year periods ended December 31, 2004, Class A shares of Pioneer Tax Free Income Fund had an average annual return of 0.05% (one year); 5.66% (five years); and 5.88% (ten years) compared to an average annual return of the Class A shares of your AmSouth Fund of -2.87% (one year); 3.96% (five years); and 4.22% (ten years), respectively, during the same period. The trustees also considered performance information provided for the one, three, and five year periods ended March 31, 2005 during which Class A shares of Pioneer Tax Free Income Fund had an average annual return of 3.30% (one year); 5.82% (three years); and 6.10% (five years), compared to an average annual return of the Class A shares of your AmSouth Fund of -0.81% (one year); 3.52% (three years); and 4.21% (five years), respectively, during 14 the same period. In addition, the Trustees considered the track record of Pioneer in managing equity and fixed income mutual funds. Fourth, the resources of Pioneer. At December 31, 2004, Pioneer managed over 80 investment companies and accounts with approximately $42 billion in assets, including $2 billion in municipal securities. Pioneer is part of the global asset management group of UniCredito Italiano S.p.A., one of the largest banking groups in Italy, providing investment management and financial services to mutual funds, institutional and other clients. As of December 31, 2004, assets under management of UniCredito Italiano S.p.A. were approximately $175 billion worldwide. Shareholders of your AmSouth Fund would become part of a significantly larger family of funds that offers a more diverse array of investment options and enhanced shareholder account options. The Pioneer family of mutual funds offers over 80 funds, including domestic and international equity and fixed income funds and a money market fund that will be available to your AmSouth Fund's shareholders through exchanges. Fifth, the Pioneer Fund's management fee is lower than your Fund's management fee and will benefit from breakpoints as assets increase as a result of the Reorganization. The aggregate Rule 12b-1 distribution and shareholder servicing fees and non-Rule 12b-1 shareholder servicing fees paid by the Class A and Class B shares of both Funds are the same. Moreover, your AmSouth Fund's Class I shares pay a non 12b-1 shareholder servicing fee that is not paid by the Pioneer Fund's Class Y shares. The net and gross expenses of Class A, Class B and Class Y shares of Pioneer Tax Free Income Fund are currently lower than the gross and net expenses of the corresponding classes of your Fund and are estimated to be lower on a pro forma basis after giving effect to the Reorganization. Sixth, although the Pioneer Tax Free Income Fund does not concentrate its investments in Tennessee and the dividends on the Pioneer Fund will not be exempt from Tennessee state taxes, your Board believes that the broader investment focus of the Pioneer Fund offered better long term prospects and potential for after tax return. Seventh, the transaction is structured to qualify as a tax-free reorganization under Section 368(a) of the Internal Revenue Code of 1986 and therefore will not be treated as a taxable sale of your AmSouth shares. Pioneer and AmSouth Bank will pay all costs of preparing and printing the Funds' proxy statements and solicitation costs incurred by the Funds in connection with the Reorganization. AAMI will otherwise be responsible for all costs and expenses of the AmSouth Fund in connection with the Reorganization. The Trustees also considered that Pioneer and AmSouth Bank will benefit from the Reorganization. See "Will Pioneer and AmSouth Bank Benefit from the Reorganizations." The Board of Trustees of the Pioneer Fund also considered that the Reorganization presents an excellent opportunity for the Pioneer Fund to acquire investment assets 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 the Pioneer Fund and its shareholders. CAPITALIZATION The following table sets forth the capitalization of each Fund as of May 31, 2005, and the pro forma combined Fund as of May 31, 2005.The table also sets forth the pro forma capitalization of the combined Fund as of May 31, 2005, assuming the shareholders of AmSouth High Quality Municipal Bond Fund approve the reorganization of their fund into Pioneer Tax Free Income Fund.

The table should not be relied upon to determine the amount of the Pioneer Fund's shares that will actually be received and distributed. BOARD'S EVALUATION AND RECOMMENDATION For the reasons described above, the Trustees, including the Independent Trustees, approved the Reorganization. In particular, the Trustees determined that the Reorganization is in the best interests of your AmSouth Fund. Similarly, the Board of Trustees of the Pioneer Fund, including its Independent Trustees, approved the Reorganization. They also determined that the Reorganization is in the best interests of the Pioneer Fund. The Trustees recommend that the shareholders of your AmSouth Fund vote FOR the proposal to approve the Agreement and Plan of Reorganization. 16 AmSouth Government Income Fund and Pioneer America Income Trust PROPOSAL 1(r) Approval of Agreement and Plan of Reorganization 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-1, because it contains details that are not in the summary. Each Fund seeks current income as is consistent with preservation of capital, and consequently, the Funds have similar investment policies and risks. Both Funds invest in U.S. government securities but the Pioneer Fund only invests in U.S. government securities backed by the full faith and credit of the U.S. Treasury. In the table below, if a row extends across the entire table, the policy disclosed applies to both your AmSouth Fund and the Pioneer Fund.

The Fund uses a "first-in, first-out" method to determine how long you have held your shares. This means that if you purchased shares on different days, the shares purchased first will be considered redeemed first for purposes of determining whether the redemption fee will be charged. The fee will be charged on all covered redemptions and exchanges, including those made through retirement plan, brokerage and other types of omnibus accounts (except where it is not practical for the plan administrator or brokerage firm to implement the fee). The Fund will not impose the redemption fee on a redemption or exchange of shares purchased upon the reinvestment of dividend and capital gain distributions. Selling shares Shares of each Fund are sold at the net asset value per share next calculated after the Fund receives your request in good order. You may sell your shares by contacting the Normally, your investment firm will send your Fund directly in writing or by telephone or by request to sell shares to PIMSS. You can also contacting a financial intermediary as sell your shares by contacting the Fund described in the Fund's prospectus. directly if your account is registered in your name. If the account is established in the shareholder's own name, shareholders may also redeem shares of the Fund by telephone or online. Comparison of Principal Risks of Investing in the Funds Because each Fund has a similar investment objective, primary investment policies and strategies, the Funds are subject to the same principal risks. You could lose money on your investment in either Fund or not make as much as if you invested elsewhere if: o Interest rates increase, causing the value of investments to decline, a risk that is generally high for longer-term bonds and low for shorter-term bonds 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 Interest rates decrease and the Fund's income declines. Income risk is generally high for shorter-term bonds and low for longer-term bonds 8 o The average life of certain types securities are extended because of slower than expected principal during periods of rising interest rates. 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 The adviser's judgment about the attractiveness, relative value or potential appreciation of a particular sector, security or investment strategy proves to be incorrect AmSouth Government Income Fund is subject to risks relating to the fact that it is non-diversified. The Fund may invest in a small number of companies which may increase the volatility of the Fund. Accordingly, the Fund's portfolio may be more sensitive to changes in the market value of a single company or industry. Past Performance Set forth below is performance information for each Fund. The bar charts show how each Fund's total return (not including any deduction for sales charges) has varied from year to year for each full calendar year. The tables show average annual total return (before and after 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 bar charts give an indication of the risks of investing in each Fund, including the fact that you could incur a loss and experience volatility of returns year to year. Past performance before and after taxes does not indicate future results.

(2) Sales charges may be reduced depending upon the amount invested or, in certain circumstances, waived. Class A shares of the Pioneer Fund bought as part of an investment of $1 million or more are not subject to an initial sales charge, but may be charged a CDSC of 1.00% if sold within one year of purchase. (3) For Class B shares purchased prior to the combination of AmSouth Funds with ISG Funds, the CDSC on such Class B shares held continuously declines over six years, starting with year one and ending in year seven from: 4%, 3%, 3%, 2%, 2%, 1%. For all other Class B shares held continuously, the CDSC declines over six years, starting with year one and ending in year seven from: 5%, 4%, 12 3%, 3%, 2%, 1%. Approximately eight years after purchase (seven years in the case of shares acquired in the ISG combination), Class B shares automatically convert to Class A shares. (4) To discourage short-term trading, a redemption fee of 2.00% will be charged on sales or exchanges of Class A, Class B and Class I shares of your AmSouth Fund made within 7 days of the date of purchase. A wire transfer fee of $7.00 will be deducted from the amount of your redemption if you request a wire transfer. (5) Other expenses for your AmSouth Fund are being limited to 0.51% for Class A shares, 0.51% for Class B shares and 0.36% for Class I shares. Any fee waiver or expense reimbursement arrangement is voluntary and may be discontinued at any time. (6) The Pioneer Fund's total annual operating expenses in the table have not been reduced by any expense offset arrangements. (7) The expenses in the table above reflect the expense limitations currently in effect for the Pioneer Fund, under which Pioneer has contractually agreed to limit ordinary operating expenses to the extent required to reduce Fund expenses to 1.30%, and 2.20% of the average daily net assets attributable to Class A and Class B shares, respectively. These expense limitations are in effect through April 1, 2008 for Class A shares and through April 1, 2006 for Class B shares. There can be no assurance that Pioneer will extend the expense limitations beyond such time. (8) Class Y shares of Pioneer America Income Trust will be offered for the first time in connection with the closing of the Reorganization. The hypothetical example below helps you compare the cost of investing in each Fund. It assumes that: (a) you invest $10,000 in each Fund for the time periods shown, (b) you reinvest all dividends and distributions, (c) your investment has a 5% return each year, (d) each Fund's gross operating expenses remain the same, and (e) the expense limitation for your Fund is in effect for year one. The examples are for comparison purposes only and are not a representation of either Fund's actual expenses or returns, either past or future.

The Trustees considered the following matters, among others, in approving the proposal. 13 First, AAMI, the investment adviser to you AmSouth Fund, and AmSouth Bank informed the Trustees that they did not intend to continue to provide investment advisory services to the AmSouth Funds. Consequently, a change in your AmSouth Fund's investment adviser was necessary. In the absence of the Reorganization, such a change would be more likely to motivate shareholders invested in reliance on AAMI's role to withdraw from the Fund, thereby reducing fund size and increasing fund expense ratios. Second, the historical investment performance of Pioneer America Income Trust is comparable to your AmSouth Fund's investment performance. For the one, five and ten year periods ended December 31, 2004, Class A shares of Pioneer America Income Trust had an average annual return of -1.86% (one year); 5.26% (five year); and 5.75% (ten year), compared to an average annual return of the Class A shares of your AmSouth Fund of -1.72% (one year); 5.12% (five year); and 6.06% (ten year), respectively, during the same period. The Trustees also considered performance information provided for the one, three, and five year periods ended March 31, 2005 during which Class A shares of Pioneer America Income Trust had an average annual return of 0.79% (one year); 4.42% (three year); and 5.57% (five year) compared to an average annual return of the Class A shares of your AmSouth Fund of 0.02% (one year); 3.99% (three year); and 5.40% (five year), respectively, during the same period. In addition, the Trustees considered the track record of Pioneer in managing equity and fixed income mutual funds. Third, the resources of Pioneer. At December 31, 2004, Pioneer managed over 80 investment companies and accounts with approximately $42 billion in assets. Pioneer is part of the global asset management group of UniCredito Italiano S.p.A., one of the largest banking groups in Italy, providing investment management and financial services to mutual funds, institutional and other clients. As of December 31, 2004, assets under management of UniCredito Italiano S.p.A. were approximately $175 billion worldwide. Shareholders of your AmSouth Fund would become part of a significantly larger family of funds that offers a more diverse array of investment options and enhanced shareholder account options. The Pioneer family of mutual funds offers over 80 funds, including domestic and international equity and fixed income funds and a money market fund that will be available to your AmSouth Fund's shareholders through exchanges. In addition, Pioneer offers shareholders additional options for their accounts, including the ability to transact and exchange shares over the telephone or online and the ability to access account values and transaction history in all of the shareholder's direct accounts in the Pioneer Funds over the telephone or online. Fourth, Pioneer America Income Trust's management fee (0.50% of average daily net assets) is the same as the advisory fee of your Fund (0.50% of average daily net assets). In addition, the Trustees considered that the broader distribution arrangements of the Pioneer Fund offer greater potential for further asset growth and reduce per share expenses. The aggregate Rule 12b-1 distribution and shareholder servicing fees and non-Rule 12b-1 shareholder servicing fees paid by the Class A and Class B shares of both Funds are the same. Moreover, your AmSouth Fund's Class I shares pay a non 12b-1 shareholder servicing fee that is not paid by the Pioneer Fund's Class Y shares. Currently, for each class of shares, your Fund's gross expenses are higher than the corresponding class of the Pioneer Fund. However, net of expense limitations, the expenses attributable to Class Y shares of the Pioneer Fund are lower than your Fund's net expenses attributable to Class I shares and the net expenses of the Pioneer Fund attributable to Class A and Class B shares are higher than the net expenses of the corresponding classes of the AmSouth Fund. On a pro forma basis, after giving effect to the Reorganization, it is estimated that the gross expenses of each class of the Pioneer America Income Trust will be lower than the gross expenses of the corresponding class of your Fund. It is also estimated that the expenses of the Pioneer America Income Trust's Class Y shares net of expense limitations will be lower than the net expenses of your Fund's Class I shares but that the net expenses of the Pioneer America Income Trust's Class A shares and Class B shares will be higher. The lower net expenses are a result of expense limitations on your AmSouth Fund that are voluntary and may be discontinued at any time. AAMI has informed the trustees that the expense limitations will be discontinued in the future. The trustees considered the positive factors associated with the Reorganization, such as greater fund assets and potential for growth, to outweigh the negative factors, such as the increase in expenses. Fifth, the Class A, B and Y shares of Pioneer America Income Trust received in the Reorganization will provide AmSouth Government Income Fund shareholders with exposure to substantially the same investment product as they currently have. Sixth, the transaction is structured to qualify as a tax-free reorganization under Section 368(a) of the Internal Revenue Code of 1986 and therefore will not be treated as a taxable sale of your AmSouth shares. Pioneer and AmSouth Bank will pay all costs of preparing and printing the Funds' proxy statements and solicitation costs incurred by the Funds in connection with the Reorganization. AAMI will otherwise be responsible for all costs and 14 expenses of your Fund in connection with the Reorganization. The Trustees also considered that Pioneer and AmSouth Bank will benefit from the Reorganization. See "Will Pioneer and AmSouth Bank Benefit from the Reorganizations." The Trustees also considered that Pioneer and AmSouth Bank will benefit from the Reorganization. See "Will Pioneer and AmSouth Bank Benefit from the Reorganizations." The Board of Trustees of the Pioneer Fund also considered that the Reorganization presents an excellent opportunity for the Pioneer Fund to acquire investment assets 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 the Pioneer Fund and its shareholders. CAPITALIZATION The following table sets forth the capitalization of each Fund as of May 31, 2005, and the pro forma combined Fund as of May 31, 2005.

The table should not be relied upon to determine the amount of the Pioneer Fund's shares that will actually be received and distributed. BOARD'S EVALUATION AND RECOMMENDATION For the reasons described above, the Trustees, including the Independent Trustees, approved the Reorganization. In particular, the Trustees determined that the Reorganization is in the best interests of your AmSouth Fund. Similarly, the Board of Trustees of the Pioneer Fund, including its Independent Trustees, approved the Reorganization. They also determined that the Reorganization is in the best interests of the Pioneer Fund. The Trustees recommend that the shareholders of your AmSouth Fund vote FOR the proposal to approve the Agreement and Plan of Reorganization. 15 AmSouth Limited Term Bond Fund and Pioneer Short Term Income Fund PROPOSAL 1(s) Approval of Agreement and Plan of Reorganization SUMMARY The following is a summary of more complete information appearing later in this Proxy Statement/Prospectus or incorporated herein.

Asset-backed securities represent participations in, or are secured by and payable from, financial assets such as 2 AmSouth Limited Term Bond Fund Pioneer Short Term Income Fund - -------------------------------------------------------------------------------------------------------------------------------- installment sales or loan contracts, leases, credit card receivables and other categories of receivables. Certain asset-backed securities present a heightened level of risk because, in the event of default, the liquidation value of the underlying assets may be inadequate or nonexistent to pay any unpaid principal or interest. 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, but remain subject to prepayment risk, which would be a loss of any expected interest payments, even though there is no default on the underlying financial asset. For mortgage derivatives and structured securities that have imbedded leverage features, 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.

Pioneer Short Term Income Fund may invest in securities of Canadian issuers to the same extent as securities of U.S. issuers. Investing in Canadian and other non-U.S. issuers, particularly issuers in emerging markets, may involve unique risks compared to investing in the securities of U.S. issuers. If a rating organization downgrades the quality rating assigned to one or more of the Fund's portfolio securities, Pioneer will consider what actions, if any, are appropriate including selling the downgraded security or purchasing additional investment grade securities as soon as it is prudent to do so.

You could lose money on your investment in either Fund or not make as much as if you invested elsewhere if: o The Fund's income declines due to a decrease in interest rates. o The possibility that an issuer cannot make timely interest and principal payments on its debt securities. The lower a security's rating, generally the greater its credit risk. 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. Risk is generally high for longer-term bonds and lower or for shorter-term bonds. o The adviser's judgment about the attractiveness, relative value or potential appreciation of a particular sector, security or hedging strategy proves to be incorrect. Certain securities issued by agencies and instrumentalities of the U.S. government in which each Fund may invest are backed by the full faith and credit of the U.S. government, but others are not insured or guaranteed by the U.S. government and may be supported only by the issuer's right to borrow from the U.S. Treasury, by the credit of the issuing agency, instrumentality or corporation, or by the U.S. in some other way. Likewise, government sponsored entities such as the Federal Home Loan Mortgage Corporation (Freddie Mac), FNMA and the 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. To the extent that Pioneer Short Term Income Fund invests significantly in asset-backed and mortgage-related securities, its exposure to prepayment and extension risks may be greater than other investments in fixed income securities. Pioneer Short Term Income Fund may be subject to the following additional risks associated with investing in non-U.S. issuers, which may involve unique risks compared to investing in securities of U.S. issuers. These risks are more pronounced to the extent the Fund invests in issuers in countries with emerging markets or if the Fund invests significantly in one 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, the adviser/subadviser might 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 10 In addition, at times, more than 25% of Pioneer Short Term Income Fund's assets may be invested in the same market segment, such as financials or technology. To the extent the Fund emphasizes 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. Past Performance Set forth below is performance information for your AmSouth Fund. The bar charts show how your AmSouth Fund's total return (not including any deduction for sales charges) has varied from year to year for each full calendar year. The tables show average annual total return (before and after taxes) for your AmSouth Fund over time for each class of shares (including deductions for sales charges) compared with a broad-based securities market index. The bar charts give an indication of the risks of investing in each Fund, including the fact that you could incur a loss and experience volatility of returns year to year.

(3) Performance for the Class I shares, which were first offered on 9/2/97, is based on the historical performance of the Fund's Class A shares, including the performance of the predecessor fund and commingled accounts (without sales charge) prior to that date.

The table above shows the impact of taxes on AmSouth Limited Term Bond Fund's returns. After-tax returns are only shown for Class A shares and Class I shares and may vary for Class B shares. The Fund's after-tax returns are calculated using the highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. In certain cases, the figure representing "Return After Taxes on Distributions and Sale of Fund Shares" may be higher than the other return figures for the same period. A higher after-tax return results when a capital loss occurs upon redemption and translates into an assumed tax deduction that benefits the shareholder. Please note that actual after-tax returns depend on an investor's tax situation and may differ from those shown. Also note that 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. 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 the AmSouth Limited Term Bond Fund, the expenses of AmSouth Limited Term Bond Fund for the period ended January 31, 2005 and (ii) for Pioneer Short Term Income Fund, the expenses of Pioneer Short Term Income Fund for the period ended February 28, 2005. Future expenses for all share classes may be greater or less.

AmSouth Bank or other financial institutions may charge their customer account fees for automatic investment and other cash management services provided in connection with investment in the Fund. (2.) Sales charges may be reduced depending upon the amount invested or, in certain circumstances, waived. Class A shares of the Pioneer Fund bought as part of an investment of $1 million or more are not subject to an initial sales charge, but may be charged a CDSC of 1.00% if sold within one year of purchase. (3.) For Class B shares purchased prior to the combination of AmSouth Funds with ISG Funds, the CDSC on such Class B shares held continuously declines over six years, starting with year one and ending in year seven from: 4%, 3%, 3%, 2%, 2%, 1%. For all other Class B shares held continuously, the CDSC declines over six years, starting with year one and ending in year seven from: 5%, 4%, 3%, 3%, 2%, 1%. Eight years after purchase (seven years in the case of shares acquired in the ISG combination), Class B shares automatically convert to Class A shares. (4.) To discourage short-term trading, a redemption fee of 2.00% will be charged on sales or exchanges of Class A, Class B and Class I shares of your AmSouth Fund made within 7 days of the date of purchase. A wire transfer fee of $7.00 will be deducted from the amount of your redemption if you request a wire transfer. 13 (5.) Other expenses for your AmSouth Fund are being limited to 0.49% for Class A shares, 0.49% for Class B shares and 0.34% for Class I shares. Any fee waiver or expense reimbursement arrangement is voluntary and may be discontinued at any time. (6.) The expenses in the table above reflect the expense limitation in effect through December 31, 2005 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 Class A expenses to 0.90% of the average daily net assets attributable to Class A shares. The portion of Fund expenses (including the amount of management fee waived) attributable to Class B and Class Y shares will be reduced only to the extent such expenses are reduced for Class A shares. Any differences in the fee waiver and expense limitation among classes result from rounding in the daily calculation of a class' net assets and expense limitation, which may exceed 0.01% annually. There can be no assurance that Pioneer will extend the expense limitation beyond December 31, 2005. The hypothetical example below helps you compare the cost of investing in each Fund. It assumes that: (a) you invest $10,000 in each Fund for the time periods shown, (b) you reinvest all dividends and distributions, (c) your investment has a 5% return each year, and (d) each Fund's gross operating expenses remain the same. The examples are for comparison purposes only and are not a representation of either Fund's actual expenses or returns, either past or future.

The Trustees considered the following matters, among others, in approving the proposal. First, AAMI, the investment adviser to your AmSouth Fund informed the Trustees that it does not intend to continue to provide investment advisory services to the AmSouth Funds. Consequently, a change in your AmSouth Fund's investment adviser was necessary. In the absence of the Reorganization, such a change would be more likely to motivate shareholders invested in reliance on AAMI's role to withdraw from the Fund, thereby reducing fund size and increasing fund expense ratios. Second, the resources of Pioneer. At December 31, 2004, Pioneer managed over 80 investment companies and accounts with approximately $42 billion in assets, including $15.7 billion in fixed income securities. Pioneer is part of the 14 global asset management group of UniCredito Italiano S.p.A., one of the largest banking groups in Italy, providing investment management and financial services to mutual funds, institutional and other clients. As of December 31, 2004, assets under management of UniCredito Italiano S.p.A. were approximately $175 billion worldwide. Shareholders of your AmSouth Fund would become part of a significantly larger family of funds that offers a more diverse array of investment options and enhanced shareholder account options. The Pioneer family of mutual funds offers over 80 funds, including domestic and international equity and fixed income funds and a money market fund that will be available to your AmSouth Fund's shareholders through exchanges. Third, Pioneer Short Term Income Fund's management fee (0.40% of average daily net assets) is lower than the advisory fee of your AmSouth Fund (0.50% of average daily net assets). The distribution and shareholder servicing fees paid by the Class A and Class B shares of both Funds are the same. Moreover, your AmSouth Fund's Class I shares pay a non 12b-1 shareholder servicing fee that is not paid by the Pioneer Fund's Class Y shares. While Pioneer Short Term Income Fund's gross and net expenses are higher than the historical gross and net expenses of your AmSouth Fund, (with the exception of the Pioneer Fund's Class Y shares) on a pro forma basis, after giving effect to the Reorganization, the gross and net expenses of each class of the Pioneer Fund are estimated to be lower than gross and net expenses of the corresponding class of your Fund. In addition, the broader distribution arrangements of the Pioneer Fund offer greater potential for further asset growth and reduce per share expenses. Fourth, the Class A, B and Y shares of Pioneer Short Term Income Fund received in the Reorganization will provide AmSouth Limited Term Bond Fund shareholders with exposure to substantially the same investment product as they currently have. Fifth, the transaction is structured to qualify as a tax-free reorganization under Section 368(a) of the Internal Revenue Code of 1986 and therefore will not be treated as a taxable sale of your AmSouth shares. Pioneer and AmSouth Bank will pay all costs of preparing and printing the AmSouth Funds' proxy statements and solicitation costs incurred by the AmSouth Funds in connection with the Reorganization. AAMI will otherwise be responsible for all costs and expenses of the AmSouth Funds in connection with the Reorganization. The Trustees also considered that Pioneer and AmSouth Bank will benefit from the Reorganization. See "Will Pioneer and AmSouth Bank Benefit from the Reorganizations." The Board of Trustees of the Pioneer Fund also considered that the Reorganization presents an excellent opportunity for the Pioneer Fund to acquire investment assets 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 the Pioneer Fund and its shareholders. CAPITALIZATION The following table sets forth the capitalization of each Fund as of May 31, 2005, and the pro forma combined Fund as of May 31, 2005.

The table should not be relied upon to determine the amount of the Pioneer Fund's shares that will actually be received and distributed. BOARD'S EVALUATION AND RECOMMENDATION For the reasons described above, the Trustees, including the Independent Trustees, approved the Reorganization. In particular, the Trustees determined that the Reorganization is in the best interests of your AmSouth Fund. Similarly, the Board of Trustees of the Pioneer Fund, including its Independent Trustees, approved the Reorganization. They also determined that the Reorganization is in the best interests of the Pioneer Fund. The Trustees recommend that the shareholders of your AmSouth Fund vote FOR the proposal to approve the Agreement and Plan of Reorganization. 16 AmSouth Treasury Reserve Money Market Fund and Pioneer Cash Reserves Fund PROPOSAL 1(t) Approval of Agreement and Plan of Reorganization SUMMARY The following is a summary of more complete information appearing later in this Proxy Statement/Prospectus or incorporated herein.

Comparison of Principal Risks of Investing in the Funds Because each Fund has a similar investment objective, primary investment policies and strategies, the Funds are subject to the same principal risks. The Pioneer Fund may be subject to greater credit risk than the AmSouth Fund because it may invest in securities other than U.S. Government securities. You could lose money on your investment in either Fund 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 In the case of Pioneer Cash Reserves Fund, 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 The adviser's judgment about the credit quality, attractiveness or relative value of a particular security proves to be incorrect Pioneer Cash Reserves Fund may be subject to the following additional risks associated with investing in non-U.S. issuers, which may involve unique risks compared to investing in securities of U.S. issuers. These risks are more pronounced to the extent the Fund invests in issuers in countries with emerging markets or if the Fund invests significantly in one country. These risks may include: o Inadequate financial information o Smaller, less liquid and more volatile markets o Political and economic upheavals Pioneer Cash Reserves does not concentrate its investments in any industry. At times, more than 25% of the Pioneer Cash Reserves Fund's assets may be invested in the same market segment, such as financials. To the extent the Fund emphasizes 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. Past Performance Set forth below is performance information for each Fund. The bar charts show how each Fund's total return has varied from year to year for each full calendar year. The tables show average annual total return for each Fund over time for each class of shares compared with a broad-based securities market index. The bar charts give an indication of the risks of 6 investing in each Fund, including the fact that you could incur a loss and experience volatility of returns year to year. Past performance does not indicate future results.

The AmSouth Treasury Reserve Money Market Fund commenced operations on 3/29/94 through a transfer of assets from certain collective trust fund ("commingled") accounts managed by AAMI, using substantially the same investment objective, polices and methodologies as the Fund. The quoted performance of the Fund includes the performance of the commingled accounts for the periods prior to the Fund's 7 commencement of operations, restated to reflect the expenses associated with the Fund. The commingled accounts were not registered with the SEC and were not subject to the investment restrictions imposed by law on registered mutual funds. If the commingled accounts had been registered, their returns may have been adversely affected. Class A Shares were first offered on 8/29/94.

(2) Class Y shares were not outstanding prior to the closing of the Reorganization and consequently have no performance history. However, the performance record of the Class Y shares would be modestly higher than the performance of the Class A and Class B shares due to the lower expenses applicable to Class Y shares. 7-Day Yield As of December 31, 2004 - ------------------------------------------------------------------------------------------------------------------- AmSouth Treasury Reserve Money Market Fund, Class A Shares 1.43% Pioneer Cash Reserves Fund, Class A Shares 1.12% AmSouth Treasury Reserve Money Market Fund, Class I Shares 1.48% The most recent portfolio manager's discussion of each Fund's performance is attached as Exhibit C. 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 the AmSouth Treasury Reserve Money Market Fund, the expenses of AmSouth Treasury Reserve Money Market Fund for the period ended January 31, 2005, and (ii) for the Pioneer Cash Reserves Fund, the expenses of Pioneer Cash Reserves Fund for the period ended December 31, 2004. Future expenses for all share classes may be greater or less. Shareholders of AmSouth Prime Money Market Fund are also being asked to approve the reorganization of their fund into Pioneer Cash Reserves Fund. The tables also show (1) the pro forma expenses of the combined Fund assuming the Reorganization occurred on December 31, 2004, and (2) the pro forma expenses of the combined Fund assuming the reorganization of AmSouth Prime Money Market Fund into Pioneer Cash Reserves Fund also occurred December 31, 2004. 8 Combined Combined Fund Fund AmSouth (including AmSouth (including Shareholder Treasury AmSouth Treasury AmSouth transaction fees Reserve Prime Money Reserve Prime Money (paid directly Money Pioneer Cash Combined Market Money Combined Market from your Market Reserves Fund (Pro Fund) (Pro Market Fund (Pro Fund) (Pro investment) Fund(1) Fund Forma) Forma) Fund(1) Forma) Forma) - --------------------------------------------------------------------------------------------------------------------------------- Class A Class A Class A Class A Class I Class Y(7) Class Y(7) - --------------------------------------------------------------------------------------------------------------------------------- Maximum sales charge (load) when you buy shares as a percentage of offering price None None None None None None None - --------------------------------------------------------------------------------------------------------------------------------- Maximum deferred sales charge (load) as a percentage of purchase price or the amount you receive when you sell shares, whichever is less None None None None None None None - --------------------------------------------------------------------------------------------------------------------------------- Redemption fees None(2) None None None None None None - --------------------------------------------------------------------------------------------------------------------------------- Annual fund operating expenses (deducted from Fund assets) (as a % of average net assets) - --------------------------------------------------------------------------------------------------------------------------------- Management fee 0.40% 0.40% 0.40% 0.40% 0.40% 0.40% 0.40% - --------------------------------------------------------------------------------------------------------------------------------- Distribution and service (12b-1) fee None 0.15% 0.15% 0.15% None 0.15% None - --------------------------------------------------------------------------------------------------------------------------------- Other expenses 0.57%(3) 0.38% 0.31% 0.17% 0.47% 0.07%(6) 0.06%(6) - --------------------------------------------------------------------------------------------------------------------------------- Total fund operating expenses 0.97% 0.93%(4) 0.86% 0.72% 0.87%(3) 0.47% 0.46% - --------------------------------------------------------------------------------------------------------------------------------- Expense reimbursement/reduction 0.27% None(5) None(5) None(5) 0.22% None(5) None(5) - --------------------------------------------------------------------------------------------------------------------------------- Net fund operating expenses 0.70% 0.93% 0.86% 0.72% 0.65% 0.47% 0.46% - --------------------------------------------------------------------------------------------------------------------------------- (1) AmSouth Bank or other financial institutions may charge their customer account fees for automatic investment and other cash management services provided in connection with investment in the Fund.

Any fee waiver or expense reimbursement arrangement is voluntary and may be discontinued at any time. (4) The Pioneer Fund's total annual operating expenses in the table have not been reduced by any expense offset arrangements. (5) Pioneer has agreed to limit the Fund's expenses or waive a portion of its management fee to maintain a net asset value of $1.00. Under certain circumstances, this limitation may result in a 0.00% yield for one or more classes for shares. From time to time, Pioneer and its affiliates may limit the expenses of one or more classes for the purpose of increasing its yield during the period of the limitation. These expense limitation policies are voluntary and temporary and may be revised or terminated by Pioneer at any time without notice. (6) Other expenses for Class Y shares are estimated based on expenses that would have been incurred for the fiscal year ended December 31, 2004 had such shares been outstanding for the entire fiscal year. (7) Class Y shares of Pioneer Cash Reserves Fund are being offered for the first time in connection with the Reorganization. The hypothetical example below helps you compare the cost of investing in each Fund. It assumes that: (a) you invest $10,000 in each Fund for the time periods shown, (b) you reinvest all dividends and distributions, (c) your investment has a 5% return each year, (d) each Fund's operating expenses remain the same and (e) you sell your shares at the end of the time period shown. The examples are for comparison purposes only and are not a representation of either Fund's actual expenses or returns, either past or future.

Reasons for the Proposed Reorganization The Trustees believe that the proposed Reorganization is in the best interests of AmSouth Treasury Reserve Money Market Fund and its shareholders. The Trustees considered the following matters, among others, in approving the proposal. First, AAMI, the investment adviser to your AmSouth Fund, informed the Trustees that it does not intend to continue to provide investment advisory services to the AmSouth Funds. Consequently, a change in your AmSouth Fund's investment adviser was necessary. In the absence of the Reorganization, such a change would be more likely to motivate shareholders invested in reliance on AAMI's role to withdraw from the Fund, thereby reducing fund size and increasing fund expense ratios. 10 Second, after the Reorganization, the combined Fund will have an asset size substantially larger than that of your AmSouth Fund, which may allow the combined Fund to achieve significant economies of scale in investments or expenses. Third, the historical investment performance of Pioneer Cash Reserves Fund is comparable to your AmSouth Fund's investment performance. For the one, five and ten year periods ended December 31, 2004, Class A shares of Pioneer Cash Reserves Fund had an average annual return of 0.45% (one year); 2.12% (five year); and 3.42% (ten year) compared to an average annual return of the Class A shares of your AmSouth Fund of 0.61% (one year); 2.15% (five year); and 3.47% (ten year), respectively, during the same period. In addition, the Trustees considered the track record of Pioneer in managing fixed income mutual funds. Fourth, the resources of Pioneer. At December 31, 2004, Pioneer managed over 80 investment companies and accounts with approximately $42 billion in assets. Pioneer is part of the global asset management group of UniCredito Italiano S.p.A., one of the largest banking groups in Italy, providing investment management and financial services to mutual funds, institutional and other clients. As of December 31, 2004, assets under management of UniCredito Italiano S.p.A. were approximately $175 billion worldwide. Shareholders of your AmSouth Fund would become part of a significantly larger family of funds that offers a more diverse array of investment options and enhanced shareholder account options. The Pioneer family of mutual funds offers over 80 funds, including domestic and international equity and fixed income funds and a money market fund that will be available to your AmSouth Fund's shareholders through exchanges. Fifth, Pioneer Cash Reserves Fund's management fee (0.40% of average daily net assets) is the same as the advisory fee of your AmSouth Fund (0.40% of average daily net assets). Although the historical net expenses of Pioneer Cash Reserves Fund are higher than your AmSouth Fund's historical net expenses, the estimated pro forma gross expenses of the Pioneer Fund after giving effect to the Reorganization are lower than your AmSouth Fund's gross expenses. In addition, with respect to Class Y shares, the pro forma expense of the Pioneer Fund, net of expense limitations, are lower than your Fund's net expenses attributable to Class I shares. The net expenses attributable to the Class A shares of the Pioneer Fund on a pro forma basis are estimated to be two basis points higher than the net expenses attributable to the Class A shares of the AmSouth Fund. However, AAMI has informed the trustees that its expense limitations will be discontinued in the future. The distribution and shareholder servicing fees paid by the Class A and Class B shares of both Funds are the same. Moreover, your AmSouth Fund's Class I shares pay a non 12b-1 shareholder servicing fee that is not paid by the Pioneer Fund's Class Y shares. In addition, the broader distribution arrangements of the Pioneer Fund offer greater potential for further asset growth and reduce per share expenses. Sixth, the substantially larger size of Pioneer Cash Reserves Fund offers greater opportunity for diversification of the investment portfolio, which should help to reduce risks. Seventh, the Class A and Y shares of Pioneer Cash Reserves Fund received in the Reorganization will provide AmSouth Treasury Reserve Money Market Fund shareholders with exposure to substantially the same investment product as they currently have. The Board considered the differences in the investment policies of the two Funds and concluded that the broader investment range of Pioneer Cash Reserves Fund did not materially increase the risk exposure to AmSouth Treasury Reserve Money Market Fund shareholders. Eighth, the transaction is structured to qualify as a tax-free reorganization under Section 368(a) of the Internal Revenue Code of 1986 and therefore will not be treated as a taxable sale of your AmSouth shares. Pioneer and AmSouth Bank will pay all costs of preparing and printing the AmSouth Funds' proxy statements and solicitation costs incurred by the AmSouth Funds in connection with the Reorganization. AAMI will otherwise be responsible of all costs and expenses of the AmSouth Funds in connection with the Reorganizations. The Trustees also considered that Pioneer and AmSouth Bank will benefit from the Reorganization. See "Will Pioneer and AmSouth Bank Benefit from the Reorganizations." The Board of Trustees of the Pioneer Fund also considered that the Reorganization presents an excellent opportunity for the Pioneer Fund to acquire investment assets 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 the Pioneer Fund and its shareholders. 11 CAPITALIZATION The following table sets forth the capitalization of each Fund as of May 31, 2005, and the pro forma combined Fund as of May 31, 2005.

The table should not be relied upon to determine the amount of the Pioneer Fund's shares that will actually be received and distributed. BOARD'S EVALUATION AND RECOMMENDATION For the reasons described above, the Trustees, including the Independent Trustees, approved the Reorganization. In particular, the Trustees determined that the Reorganization is in the best interests of your AmSouth Fund. Similarly, the Board of Trustees of the Pioneer Fund, including its Independent Trustees, approved the Reorganization. They also determined that the Reorganization is in the best interests of the Pioneer Fund. The Trustees recommend that the shareholders of your AmSouth Fund vote FOR the proposal to approve the Agreement and Plan of Reorganization. 12 AmSouth Prime Money Market Fund and Pioneer Cash Reserves Fund PROPOSAL 1(u) Approval of Agreement and Plan of Reorganization SUMMARY The following is a summary of more complete information appearing later in this Proxy Statement/Prospectus or incorporated herein.

Even though each Fund seeks to maintain a constant net asset value of $1.00, you could lose money on your investment in either Fund 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 may not be able to make timely payments because of a general economic downturn or increased governmental costs o The adviser's judgment about the credit quality, attractiveness or relative value of a particular security proves to be incorrect Pioneer Cash Reserves Fund may be subject to the following additional risks associated with investing in non-U.S. issuers, which may involve unique risks compared to investing in securities of U.S. issuers. These risks are more pronounced to the extent the Fund invests in issuers in countries with emerging markets or if the Fund invests significantly in one country. These risks may include: o Inadequate financial information o Smaller, less liquid and more volatile markets o Political and economic upheavals Pioneer Cash Reserves does not concentrate its investments in any industry. At times, more than 25% of the Pioneer Cash Reserves Fund's assets may be invested in the same market segment, such as financials. To the extent the Fund emphasizes 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. Past Performance Set forth below is performance information for each Fund. The bar charts show how each Fund's total return (not including any deduction for sales charges) has varied from year to year for each full calendar year. The tables show average annual total return (before and after 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 bar charts give an indication of the risks of investing in each Fund, including the fact that you could incur a loss and experience volatility of returns year to year. Past performance before and after taxes does not indicate future results. No Class Y shares of Pioneer Cash Reserves Fund are currently outstanding. 7 AmSouth Prime Money Market Fund -- Class A Shares Calendar Year Total Returns* [The following table was depicted as a bar chart in the printed material.] 1995 1996 1997 1998 1999 2000 2001 2002 2003 2004 5.5 4.84 4.98 4.88 4.49 5.73 3.46 0.98 0.39 0.60 * During the period shown in the bar chart, your AmSouth Fund's highest quarterly return was 1.48% for the quarter ended December 31, 2000, and the lowest quarterly return was 0.08% for the quarter ended December 31, 2003.

For all other Class B shares held continuously, the CDSC declines over six years, starting with year one and ending in year seven from: 5%, 4%, 3%, 3%, 2%, 1%. Eight years after purchase (seven years in the case of shares acquired in the ISG combination), Class B shares automatically convert to Class A shares. (3) A wire transfer fee of $7.00 will be deducted from the amount of your redemption if you request a wire transfer. (4) Other expenses for your AmSouth Fund are being limited to 0.40% for Class A shares, 0.20% for Class B shares and 0.25% for Class I shares. Any fee waiver or expense reimbursement arrangement is voluntary and may be discontinued at any time. (5) The Pioneer Fund's total annual operating expenses in the table have not been reduced by any expense offset arrangements. (6) Pioneer has agreed to limit the Fund's expenses or waive a portion of its management fee to maintain a net asset value of $1.00. Under certain circumstances, this limitation may result in a 0.00% yield for one or more classes for shares. From time to time, Pioneer and its affiliates may limit the expenses of one or more classes for the purpose of increasing its yield during the period of the limitation. These expense limitation policies are voluntary and temporary and may be revised or terminated by Pioneer at any time without notice. 11 (7) Other expenses for Class Y shares are estimated based on expenses that would have been incurred for the fiscal year ended December 31, 2004 had such shares been outstanding for the entire fiscal year. (8) Class Y shares of Pioneer Cash Reserves Fund are being offered for the first time in connection with the Reorganization. 12 The hypothetical example below helps you compare the cost of investing in each Fund. It assumes that: (a) you invest $10,000 in each Fund for the time periods shown, (b) you reinvest all dividends and distributions, (c) your investment has a 5% return each year, and (d) each Fund's operating expenses remain the same. The examples are for comparison purposes only and are not a representation of either Fund's actual expenses or returns, either past or future. - --------------------------------------------------------------------------------------------------------- Combined Fund (including AmSouth Treasury Reserve Number of years you AmSouth Prime Money Pioneer Cash Reserves Combined Fund Money Market Fund) own your shares Market Fund Fund (Pro Forma) (Pro Forma) - --------------------------------------------------------------------------------------------------------- Class A - --------------------------------------------------------------------------------------------------------- Year 1 $98 $95 $645 $644 - --------------------------------------------------------------------------------------------------------- Year 3 $306 $296 $795 $792 - --------------------------------------------------------------------------------------------------------- Year 5 $531 $515 $958 $953 - --------------------------------------------------------------------------------------------------------- Year 10 $1,178 $1,143 $1,429 $1,418 - --------------------------------------------------------------------------------------------------------- Class B -- assuming redemption at end of period - --------------------------------------------------------------------------------------------------------- Year 1 $704 $584 $581 $582 - --------------------------------------------------------------------------------------------------------- Year 3 $930 $869 $860 $863 - --------------------------------------------------------------------------------------------------------- Year 5 $1,283 $1,080 $1,064 $1,070 - --------------------------------------------------------------------------------------------------------- Year 10 $2,066 $1,895 $1,817 $1,823 - --------------------------------------------------------------------------------------------------------- Class B -- assuming no redemption - --------------------------------------------------------------------------------------------------------- Year 1 $204 $184 $181 $182 - --------------------------------------------------------------------------------------------------------- Year 3 $630 $569 $560 $563 - --------------------------------------------------------------------------------------------------------- Year 5 $1,083 $980 $964 $970 - --------------------------------------------------------------------------------------------------------- Year 10 $2,066 $1,895 $1,817 $1,823 - --------------------------------------------------------------------------------------------------------- Class I Class Y - --------------------------------------------------------------------------------------------------------- Year 1 $88 N/A $47 $47 - --------------------------------------------------------------------------------------------------------- Year 3 $274 N/A $148 $148 - --------------------------------------------------------------------------------------------------------- Year 5 $477 N/A $258 $258 - --------------------------------------------------------------------------------------------------------- Year 10 $1061 N/A $579 $579 - --------------------------------------------------------------------------------------------------------- Reasons for the Proposed Reorganization The Trustees believe that the proposed Reorganization is in the best interests of AmSouth Prime Money Market Fund and its shareholders. The Trustees considered the following matters, among others, in approving the proposal. First, AAMI, the investment adviser to your AmSouth Fund, informed the Trustees that it does not intend to continue to provide investment advisory services to the AmSouth Funds. Consequently, a change in your AmSouth Fund's investment adviser was necessary. In the absence of the Reorganization, such a change would be more likely to motivate shareholders invested in reliance on AAMI's role to withdraw from the Fund, thereby reducing fund size and increasing fund expense ratios. Second, the historical investment performance of Pioneer Cash Reserves Fund is comparable to your AmSouth Fund's investment performance. For example, the one, five and ten year periods ended December 31, 2004, Class A shares of Pioneer Cash Reserves Fund had an average annual return of 0.45% (one year); 2.12% (five year); and 3.42% (ten year) compared to an average annual return of the Class A shares of your AmSouth Fund of 0.60% (one year); 2.20% (five year); and 3.56% (ten year), respectively, during the same period. In addition, the Trustees considered the track record of Pioneer in managing equity and fixed income mutual funds. Third, the resources of Pioneer. At December 31, 2004, Pioneer manages over 80 investment companies and accounts with approximately $42 billion in assets. Pioneer is part of the global asset management group of UniCredito Italiano S.p.A., one of the largest banking groups in Italy, providing investment management and financial services to mutual funds, institutional and other clients. As of December 31, 2004, assets under management of UniCredito Italiano S.p.A. were 13 approximately $175 billion worldwide. Shareholders of your AmSouth Fund would become part of a significantly larger family of funds that offers a more diverse array of investment options and enhanced shareholder account options. The Pioneer family of mutual funds offers over 80 funds, including domestic and international equity and fixed income funds and a money market fund that will be available to your AmSouth Fund's shareholders through exchanges. Fourth, Pioneer Cash Reserves Fund's management fee (0.40% of average daily net assets) is the same as the advisory fee of your AmSouth Fund (0.40% of average daily net assets). The gross expenses of each class of the Pioneer Fund, on both a historical and pro-forma basis, are lower than the gross expenses attributable to the corresponding class of your Fund. Expenses, net of limitations, on a pro forma basis for the Class A and Class Y shares of the Pioneer Fund are lower than the net expenses of the corresponding Class of your Fund. With respect to Class B shares, your Fund's historical net expenses are lower than the pro-forma expenses attributable to the Class B shares of the Pioneer Fund. The pro forma expenses of Class B shares net of limitations will increase 84 basis points. The lower net expenses on your AmSouth Fund are a result of voluntary expense limitations that may be discontinued at any time. AmSouth Bank and its affiliates have informed the trustees that they will discontinue their expense limitations in the future. The trustees considered the positive factors associated with the Reorganization, such as greater fund assets and potential for growth, to outweigh the negative factors, such as the increase in net expenses for the Class B shares. The aggregate Rule 12b-1 distribution and shareholder servicing fees and non-Rule 12b-1 shareholder servicing fees paid by the Class A and Class B shares of both Funds are the same. Moreover, your AmSouth Fund's Class I shares pay a non 12b-1 shareholder servicing fee that is not paid by the Pioneer Fund's Class Y shares. In addition, the broader distribution arrangements of the Pioneer Fund offer greater potential for further asset growth and reduce per share expenses. Fifth, the substantially larger size of the combined Pioneer Cash Reserves Fund will offer greater opportunity for diversification of the investment portfolio, which should help to reduce risks. Sixth, the Class A, B and Y shares of Pioneer Cash Reserves Fund received in the Reorganization will provide AmSouth Prime Money Market Fund shareholders with exposure to substantially the same investment product as they currently have. Seventh, the transaction is structured to qualify as a tax-free reorganization under Section 368(a) of the Internal Revenue Code of 1986 and therefore will not be treated as a taxable sale of your AmSouth shares. Pioneer and AmSouth Bank will pay all costs of preparing and printing the AmSouth Funds' proxy statements and solicitation costs incurred by the AmSouth Funds in connection with the Reorganization. AAMI will otherwise be responsible for all costs and expenses of the AmSouth Funds in connection with the Reorganizations. The Trustees also considered that Pioneer and AmSouth Bank will benefit from the Reorganization. See "Will Pioneer and AmSouth Bank Benefit from the Reorganizations." The Board of Trustees of the Pioneer Fund also considered that the Reorganization presents an excellent opportunity for the Pioneer Fund to acquire investment assets 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 the Pioneer Fund and its shareholders. 14 CAPITALIZATION The following table sets forth the capitalization of each Fund as of May 31, 2005, and the pro forma combined Fund as of May 31, 2005.

The table should not be relied upon to determine the amount of the Pioneer Fund's shares that will actually be received and distributed. BOARD'S EVALUATION AND RECOMMENDATION For the reasons described above, the Trustees, including the Independent Trustees, approved the Reorganization. In particular, the Trustees determined that the Reorganization is in the best interests of your AmSouth Fund. Similarly, the Board of Trustees of the Pioneer Fund, including its Independent Trustees, approved the Reorganization. They also determined that the Reorganization is in the best interests of the Pioneer Fund. The Trustees recommend that the shareholders of your AmSouth Fund vote FOR the proposal to approve the Agreement and Plan of Reorganization. 15 AmSouth Tax-Exempt Money Market Fund and Pioneer Tax Free Money Market Fund PROPOSAL 1(v) Approval of Agreement and Plan of Reorganization 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-1, because it contains details that are not in the summary. Each Fund is a money market fund that may invest in high quality short-term instruments that are exempt from regular federal income tax. Consequently, the policies and risks of each Fund are similar. A portion of the income from Pioneer Tax Free Money Market Fund may be a preference item for purposes of the federal alternative minimum tax.

AAMI generally evaluates investments based on interest rate sensitivity selecting those securities whose maturities fit the Fund's interest rate sensitivity target and which AAMI believes to be the best relative values. The Fund will maintain an average weighted portfolio maturity of 90 days or less and will limit the maturity of each security in its portfolio to 397 days or less. - --------------------------------------------------------------------------------------------------------------------------- 2 - ---------------------------------------------------------------------------------------------------------------------------- AmSouth Tax-Exempt Money Market Fund Pioneer Tax Free Money Market Fund - ---------------------------------------------------------------------------------------------------------------------------- - ---------------------------------------------------------------------------------------------------------------------------- Other investments The Fund may invest up to 20% of its total The Fund may invest up to 20% of its net assets in taxable obligations.

The bar charts show how each Fund's total return has varied from year to year for each full calendar year. The table shows average annual total return for each Fund over time for each class of shares compared with a broad-based securities market index. The bar charts give an indication of the risks of investing in each Fund, including the fact that you could incur a loss and experience volatility of returns year to year. Past performance does not indicate future results. No Class Y shares of Pioneer Tax Exempt Money Market Fund are currently outstanding.

Pursuant to an agreement and plan of reorganization, Pioneer Tax Exempt Money Market Fund acquired all of the assets and those liabilities reflected in the net assets of Safeco Tax-Free Money Free Money Market Fund (the predecessor fund) on December 10, 2004. In the reorganization, the predecessor fund exchanged all of its assets for Investor Class shares of the Pioneer Fund. The predecessor fund offered an Investor Class and other classes of shares similar to the Fund's Class A, B and C shares. As a result of the reorganization, Pioneer Tax Exempt Money Market Fund is the accounting successor of the predecessor fund. The predecessor fund operated as a registered investment company like the Fund. The performance of each class of the Fund 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. If all the expenses of Pioneer Tax Exempt Money Market Fund were reflected, the performance would be lower. Since August 2, 2004, Pioneer has served as the predecessor fund's investment adviser. Safeco Asset Management, Inc. previously served as the predecessor fund's investment adviser. The Fund's Investor Class shares are not offered in the reorganization.

The Trustees considered the following matters, among others, in approving the proposal. First, AAMI, the investment adviser to your AmSouth Fund informed the Trustees that it does not intend to continue to provide investment advisory services to the AmSouth Funds. Consequently, a change in your AmSouth Fund's investment adviser was necessary. In the absence of the Reorganization, such a change would be more likely to motivate shareholders invested in reliance on AAMI's role to withdraw from the Fund, thereby reducing fund size and increasing fund expense ratios. Second, the long-term historical investment performance of Pioneer Tax Free Money Market Fund is superior to your AmSouth Fund's investment performance. For the one and five year periods ended December 31, 2004, Class A shares of Pioneer Tax Free Money Market Fund had an average annual return of 0.47% (one year) and 6.99% (five year), compared to an average annual return of the Class A shares of your AmSouth Fund of 0.56% (one year) and 1.35% (five year), respectively, during the same period. In addition, the Trustees considered the track record of Pioneer in managing equity and fixed income mutual funds. Third, the resources of Pioneer. At December 31, 2004, Pioneer managed over 80 investment companies and accounts with approximately $42 billion in assets. Pioneer is part of the global asset management group of UniCredito Italiano S.p.A., one of the largest banking groups in Italy, providing investment management and financial services to mutual funds, institutional and other clients. As of December 31, 2004, assets under management of UniCredito Italiano S.p.A. were approximately $175 billion worldwide. Shareholders of your AmSouth Fund would become part of a significantly larger family of funds that offers a more diverse array of investment options and enhanced shareholder account options. The Pioneer family of mutual funds offers over 80 funds, including domestic and international equity and fixed income funds and a money market fund that will be available to your AmSouth Fund's shareholders through exchanges. Fourth, Pioneer Tax Free Money Market Fund's management fee (0.40% of average daily net assets) is the same as the advisory fee of your AmSouth Fund (0.40% of average daily net assets). The historical expenses attributable to the Class A shares of the Pioneer Fund are higher than your Fund's Class A shares, on both a gross and net basis. On a pro forma basis, the gross expenses of the Pioneer Fund attributable to Class A expenses are estimated to be lower than your Fund's gross expenses; however, your Fund's net expenses attributable to Class A expenses are estimated to be lower than the pro forma net expenses attributable to Class A shares. However, AAMI has advised your Trustees that it will discontinue the expense limitation in the future. With respect to Class Y shares, the pro forma gross and net expenses of the Pioneer Fund are lower than the gross and net expenses of the Class I shares of your Fund. The aggregate Rule 12b-1 distribution and shareholder servicing fees and non-Rule 12b-1 shareholder servicing fees paid by the Class A and Class B shares of both Funds are the same. Moreover, your AmSouth Fund's Class I shares pay a non 12b-1 shareholder servicing fee that is not paid by the Pioneer Fund's Class Y shares. In addition, the broader distribution arrangements of the Pioneer Fund offer greater potential for further asset growth and reduced per share expenses. Fifth the Class A shares of Pioneer Tax Free Money Market Fund received in the Reorganization will provide AmSouth Tax-Exempt Money Market Fund shareholders with exposure to substantially the same investment product as they currently have. Sixth, the transaction is structured to qualify as a tax-free reorganization under Section 368(a) of the Internal Revenue Code of 1986 and therefore will not be treated as a taxable sale of your AmSouth shares. Pioneer and AmSouth Bank will pay all costs of preparing and printing the AmSouth Funds' proxy statements and solicitation costs incurred by the AmSouth Funds in connection with the Reorganization. AAMI will otherwise be responsible of all costs and expenses of the AmSouth Funds in connection with the Reorganization. 11 The Trustees also considered that Pioneer and AmSouth Bank will benefit from the Reorganization. See "Will Pioneer and AmSouth Bank Benefit from the Reorganizations." The Board of Trustees of the Pioneer Fund also considered that the Reorganization presents an excellent opportunity for the Pioneer Fund to acquire investment assets 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 the Pioneer Fund and its shareholders.

The table should not be relied upon to determine the amount of the Pioneer Fund's shares that will actually be received and distributed. BOARD'S EVALUATION AND RECOMMENDATION For the reasons described above, the Trustees, including the Independent Trustees, approved the Reorganization. In particular, the Trustees determined that the Reorganization is in the best interests of your AmSouth Fund. Similarly, the Board of Trustees of the Pioneer Fund, including its Independent Trustees, approved the Reorganization. They also determined that the Reorganization is in the best interests of the Pioneer Fund. The Trustees recommend that the shareholders of your AmSouth Fund vote FOR the proposal to approve the Agreement and Plan of Reorganization. 12 AmSouth Institutional Prime Obligations Money Market Fund and Pioneer Institutional Money Market Fund PROPOSAL 1(w) Approval of Agreement and Plan of Reorganization 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-2, because it contains details that are not in the summary. Each Fund is a money market fund that may invest in high quality short-term instruments. Consequently, the policies and risks of each Fund are similar.

To the extent the Fund emphasizes 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. In selecting the Fund's portfolio, Pioneer complies with the rating, maturity and diversification requirements applicable to money market funds. Within those limits, Pioneer's assessment of broad economic factors that are expected to affect economic activity and interest rates influence its securities selection. 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. - --------------------------------------------------------------------------------------------------------------------------------- Temporary defensive Pioneer Cash Reserves Fund may invest all or part strategies of its assets in securities with remaining maturities of less than one year, cash equivalents or may hold cash. - --------------------------------------------------------------------------------------------------------------------------------- Diversification Each Fund is subject to the diversification requirements applicable to money market funds under the Investment Company Act. - --------------------------------------------------------------------------------------------------------------------------------- Industry AmSouth Institutional Prime Obligations Money Pioneer Institutional Money Market Fund may not concentration Market Fund may not purchase any securities which concentrate its investments in a particular would cause more than 25% of the value of the industry.

The Trustees considered the following matters, among others, in approving the proposal. First, AAMI, the investment adviser to the Fund, informed the Trustees that it does not intend to continue to provide investment advisory services to the AmSouth Funds. Consequently, a change in your AmSouth Fund's investment adviser was necessary. In the absence of the Reorganization, such a change would be more likely to motivate shareholders invested in reliance on AAMI's role to withdraw from the Fund, thereby reducing fund size and increasing fund expense ratios. Second, the resources of Pioneer. At December 31, 2004, Pioneer managed over 80 investment companies and accounts with approximately $42 billion in assets. Pioneer is part of the global asset management group of UniCredito Italiano S.p.A., one of the largest banking groups in Italy, providing investment management and financial services to mutual funds, institutional and other clients. As of December 31, 2004, assets under management of UniCredito Italiano S.p.A. were approximately $175 billion worldwide. Shareholders of your AmSouth Fund would become part of a significantly larger family of funds that offers a more diverse array of investment options and enhanced shareholder account options. The Pioneer family of mutual funds offers over 80 funds, including domestic and international equity and fixed income funds and a money market fund that will be available to your AmSouth Fund's shareholders through exchanges. In addition, Pioneer offers shareholders additional options for their accounts, including the ability to transact and exchange shares over the telephone or online and the ability to access account values and transaction history in all of the shareholder's direct accounts in the Pioneer Funds over the telephone or online. Third, Pioneer Institutional Money Market Fund's management fee (0.20% of average daily net assets) will be the same as the advisory fee of your Fund (0.20% of average daily net assets). The aggregate Rule 12b-1 distribution and shareholder servicing fees and non-Rule 12b-1 shareholder servicing fees paid by both Funds will be the same. The gross 10 expenses of each class of the Pioneer Fund are estimated to be lower than the gross expenses of the corresponding class of the AmSouth Fund. Net of expense limitations, the expenses of the Class 1 and Class 3 shares of the Pioneer Fund are estimated to be the same as net expenses of the corresponding class of the AmSouth Fund. The estimated net expenses of the Class 2 shares of the Pioneer Fund are estimated to be one basis point higher than the net expenses of the Class 2 shares of the AmSouth Fund. AAMI has informed the trustees that the expense limitations will be discontinued in the future. Fourth, the Institutional Class 1, Institutional Class 2 and Institutional Class 3 shares of Pioneer Fund received in the Reorganization will provide AmSouth Institutional Prime Obligations Money Market Fund shareholders with exposure to substantially the same investment product as they currently have. Fifth, the transaction is structured to qualify as a tax-free reorganization under Section 368(a) of the Internal Revenue Code of 1986 and therefore will not be treated as a taxable sale of your AmSouth shares. Pioneer and AmSouth Bank will pay all costs of preparing and printing the Funds' proxy statements and solicitation costs incurred by the Funds in connection with the Reorganization. AAMI will otherwise be responsible of all costs and expenses of AmSouth Fund in connection with the Reorganizations. The Trustees also considered that Pioneer and AmSouth Bank will benefit from the Reorganization. See "Will Pioneer and AmSouth Bank Benefit from the Reorganizations." The Board of Trustees of the Pioneer Fund also considered that the Reorganization presents an excellent opportunity for the Pioneer Fund to acquire investment assets 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 the Pioneer Fund and its shareholders. CAPITALIZATION The following table sets forth the capitalization of AmSouth Institutional Prime Obligations Money Market Fund as of May 31, 2005. - ------------------------------------------------------------------------------------------------------------- AmSouth Institutional Pioneer Pro Forma Pioneer Prime Obligations Institutional Money Institutional Money Money Market Fund Market Fund Market Fund May 31, 2005 May 31, 2005 May 31, 2005 - ------------------------------------------------------------------------------------------------------------- Total Net Assets (in thousands) $374,130 N/A $374,130 - ------------------------------------------------------------------------------------------------------------- Institutional Class 1 shares ........ $185,856 N/A $185,856 - ------------------------------------------------------------------------------------------------------------- Institutional Class 2 shares ........ $139,943 N/A $139,943 - ------------------------------------------------------------------------------------------------------------- Institutional Class 3 shares ........ $48,331 N/A $48,331 - ------------------------------------------------------------------------------------------------------------- Net Asset Value Per Share - ------------------------------------------------------------------------------------------------------------- Institutional Class 1 shares ........ $1.00 N/A $1.00 - ------------------------------------------------------------------------------------------------------------- Institutional Class 2 shares ........ $1.00 N/A $1.00 - ------------------------------------------------------------------------------------------------------------- Institutional Class 3 shares ........ $1.00 N/A $1.00 - ------------------------------------------------------------------------------------------------------------- Shares Outstanding - ------------------------------------------------------------------------------------------------------------- Institutional Class 1shares ......... 185,860,023 N/A 185,860,023 - ------------------------------------------------------------------------------------------------------------- Institutional Class 2 shares ........ 139,943,961 N/A 139,943,961 - ------------------------------------------------------------------------------------------------------------- Institutional Class 3 shares ........ 48,331,683 N/A 48,331,683 - ------------------------------------------------------------------------------------------------------------- It is impossible to predict how many shares of the Pioneer Fund will actually be received and distributed by your AmSouth Fund on the Reorganization date. The table should not be relied upon to determine the amount of the Pioneer Fund's shares that will actually be received and distributed. BOARD'S EVALUATION AND RECOMMENDATION For the reasons described above, the Trustees, including the Independent Trustees, approved the Reorganization. In particular, the Trustees determined that the Reorganization is in the best interests of your AmSouth Fund. Similarly, the Board of Trustees of the Pioneer Fund, including its Independent Trustees, approved the Reorganization. They also determined that the Reorganization is in the best interests of the Pioneer Fund. 11 The Trustees recommend that the shareholders of your AmSouth Fund vote FOR the proposal to approve the Agreement and Plan of Reorganization. 12 TERMS OF EACH AGREEMENT AND PLAN OF REORGANIZATION The Reorganizations o Each Reorganization is scheduled to occur at 4:00 p.m., Eastern time, on [ ], 2005, unless your AmSouth Fund and the corresponding Pioneer Fund agree in writing to a later date. Your AmSouth Fund will transfer all of its assets to the corresponding Pioneer Fund. The corresponding Pioneer Fund will assume your AmSouth Fund's liabilities that are included in the calculation of your AmSouth Fund's net asset value on the Closing Date. The net asset value [of both Funds] will be computed as of 4:00 p.m., Eastern time, on the Closing Date. o Each Pioneer Fund (other than Pioneer Institutional Money Market Fund) will issue to the corresponding AmSouth Fund Class A, B and Y shares with an aggregate net asset value equal to the net assets attributable to the corresponding AmSouth Fund's Class A, B and I shares. These shares will immediately be distributed to your AmSouth Fund's shareholders in proportion to the relative net asset value of their holdings of your AmSouth Fund's shares on the Closing Date. As a result, each AmSouth Fund's shareholders will end up as Class A, B, or Y class shareholders of the corresponding Pioneer Fund. o In the case of Pioneer Institutional Money Market Fund, Class 1, 2 and 3 shares will be distributed in exchange for Institutional Class 1, 2 and 3 shares of AmSouth Institutional Prime Obligations Money Market Fund. These shares will immediately be distributed to AmSouth Institutional Prime Obligations Money Market Fund's shareholders in proportion to the relative net asset value of their holdings of AmSouth Institutional Prime Obligations Money Market Fund's shares on the Closing Date. As a result, AmSouth Institutional Prime Obligations Money Market Fund's shareholders will end up as Class 1, 2 or 3 shareholders of Pioneer Institutional Money Market Fund. o After the distribution of shares, your AmSouth Fund will be liquidated and dissolved. o Each Reorganization is intended to result in no income, gain or loss being recognized for federal income tax purposes and will not take place unless both 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 each AmSouth Fund are being asked to approve an Agreement and Plan of Reorganization substantially in the form attached as EXHIBIT A-1 or A-2 (each, a "Plan"). The description of the Plan contained herein is qualified in its entirety by the attached copies, as appropriate. Conditions to Closing each Reorganization. The obligation of each Fund to consummate each Reorganization is subject to the satisfaction of certain conditions, including each Fund's performance of all of its obligations under the Plan, the receipt of certain documents and financial statements from your AmSouth Fund and the receipt of all consents, orders and permits necessary to consummate the Reorganization (see Sections 7 and 8 of the Plan). The consummation of each Reorganization is not contingent on consummation of any other Reorganization. The obligations of both Funds are subject to the approval of the Plan by the necessary vote of the outstanding shares of your AmSouth Fund, in accordance with the provisions of AmSouth Funds' trust instrument 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 United States federal income tax consequences of each Reorganization (see Section 8.5 of the Plan). Termination of the Plan. The board of either the AmSouth Funds or the corresponding Pioneer Fund may terminate the Plan (even if the shareholders of your AmSouth Fund have already approved it) at any time before the Closing Date, if that board believes in good faith that proceeding with the Reorganization would no longer be in the best interests of shareholders. 9 TAX STATUS OF EACH REORGANIZATION Each Reorganization is intended to result in no income, gain or loss being recognized for United States federal income tax purposes and will not take place unless both Funds involved in the Reorganization receive a satisfactory opinion from Wilmer Cutler Pickering Hale and Dorr LLP, counsel to the Pioneer Funds, substantially to the effect that each 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 AmSouth Fund upon (1) the transfer of all of its assets to the corresponding Pioneer Fund as described in this Proxy Statement/Prospectus or (2) the distribution by your AmSouth Fund of Pioneer Fund shares to your AmSouth Fund's shareholders; o No gain or loss will be recognized by the corresponding Pioneer Fund upon the receipt of your AmSouth Fund's assets solely in exchange for the issuance of Pioneer Fund shares to your AmSouth Fund and the assumption of your AmSouth Fund's liabilities by the Pioneer Fund; o The basis of the assets of your AmSouth Fund acquired by the corresponding Pioneer Fund will be the same as the basis of those assets in the hands of your AmSouth Fund immediately before the transfer; o The tax holding period of the assets of your AmSouth Fund in the hands of the corresponding Pioneer Fund will include your AmSouth Fund's tax holding period for those assets; o You will not recognize gain or loss upon the exchange of your shares of your AmSouth Fund solely for the Pioneer Fund shares as part of the Reorganization; o The basis of the Pioneer Fund shares received by you in the Reorganization will be the same as the basis of your shares of your AmSouth Fund surrendered in the exchange; and o The tax holding period of the Pioneer Fund shares you receive will include the tax holding period of the shares of your AmSouth Fund surrendered in the exchange, provided that you held the shares of your AmSouth Fund as capital assets on the date of the exchange. In rendering such opinions, counsel shall rely upon, among other things, reasonable assumptions as well as representations of your AmSouth Fund and the Pioneer Fund (see the annexes to the Plan). No tax ruling has been or will be received from the Internal Revenue Service ("IRS") in connection with the Reorganizations. 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. You should consult your tax adviser for the particular tax consequences to you of the Reorganizations, including the applicability of any state, local or foreign tax laws. 10 VOTING RIGHTS AND REQUIRED VOTE Each share of your AmSouth Fund is entitled to one vote and each fractional share shall be entitled to a proportionate fractional vote. A quorum is required to conduct business at the Meeting. With respect to each AmSouth Fund, the presence in person or by proxy of a majority of the outstanding shares of an AmSouth Fund entitled to cast votes at the Meeting will constitute a quorum with respect to that AmSouth Fund. A favorable vote of a "majority of the outstanding voting securities" of the applicable AmSouth Fund is required to approve each Proposal. Under the Investment Company Act, the vote of a majority of the outstanding voting securities means the affirmative vote of the lesser of (i) 67% or more of the shares of the applicable AmSouth Fund represented at the meeting, if at least 50% of all outstanding shares of the AmSouth Fund are represented at the meeting, or (ii) 50% or more of the outstanding shares of the AmSouth Fund entitled to vote at the meeting. - ------------------------------------------------------------------------------------------------------------------------------- Shares Quorum Voting - ------------------------------------------------------------------------------------------------------------------------------- In General All shares "present" in person or by Shares "present" in person will be voted proxy are counted towards a quorum. in person at the Meeting.

Most of the Pioneer Funds are series of Delaware Statutory Trusts. The following is a summary of the principal differences between Delaware Statutory Trusts and Massachusetts Business 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 (such as the shareholders of Europe Fund) 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 11 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. 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 Investment Company Act of 1940, as amended (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 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, institutions and other clients. As of December 31, 2004, assets under management were approximately $175 billion worldwide, including over $42 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 each of Pioneer Fund's investment adviser and subadviser, if any, and determining whether to approve and renew the fund's investment advisory agreement and the subadvisory agreements. Pioneer has received an order (the "Exemptive Order") from the SEC that permits Pioneer, subject to the approval of the Pioneer Funds' Board of Trustees, to hire and terminate a subadviser or to materially modify an existing subadvisory agreement for a Pioneer Fund without shareholder approval. Pioneer retains the ultimate responsibility to oversee and recommend the hiring, termination and replacement of any subadviser. To the extent that the SEC adopts a rule that would supersede the Exemptive Order, Pioneer and the Pioneer Funds intend to rely on such rule to permit Pioneer, subject to the approval of the Pioneer Funds' Board of Trustees and any other applicable conditions of the rule, to hire and terminate a subadviser or to materially modify an existing subadvisory agreement for a Pioneer Fund without shareholder approval. Buying, Exchanging and Selling Shares of the Pioneer Funds Net Asset Value. Each Pioneer 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 Pioneer 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 Pioneer 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, a 12 Pioneer Fund will use a security's fair value. Fair value is the valuation of a security determined on the basis of factors other than market value in accordance with procedures approved by the Pioneer Funds' trustees. Each Pioneer Fund also may use 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 due to factors affecting one or more relevant securities markets or the specific issuer. The use of fair value pricing by a Pioneer Fund may cause the net asset value of its shares to differ from the net asset value that would be calculated using closing market prices. International securities markets may be open on days when the U.S. markets are closed. For this reason, the value of any international securities owned by a Pioneer Fund could change on a day you cannot buy or sell shares of the fund. Each Pioneer Fund may use a pricing service or a pricing matrix to value some of its assets. Debt securities with remaining maturities of 60 days or less are valued at amortized cost, which is a method of determining a security's fair value. Pioneer International Core Equity Fund primarily invests in securities of non-U.S. issuers and the markets for these securities generally close prior to the time the Fund determines its net asset value. However, the value of these securities continues to be influenced by changes in the global markets. Consequently, the trustees have determined to use the fair value of these securities as of the time the fund determines its net asset value, based upon data from a pricing service. On a daily basis, the pricing service recommends changes, based upon a proprietary model, to the closing market prices of each non-U.S. security held by the fund to reflect the security's fair value at the time the fund determines its net asset value. The fund applies these recommendations in accordance with procedures approved by the trustees. A security's fair value determined in this manner may differ from the security's closing market price on the date the fund determines its net asset value or the opening price of the security on the next business day. The fund's use of this method may significantly affect its net asset value compared to the net asset value that would have been determined using closing market prices. The fund also may take other factors influencing specific markets or issuers into consideration in determining the fair value of a non-U.S. security. 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. However, the Class A shares of the Pioneer Funds you receive in the Reorganizations will not be subject to any sales charge. When you buy Class B shares, you do not pay an initial sales charge but impose a contingent deferred sales charge. However, if you sell within five years of purchase, you will pay a contingent deferred sales charge. The Class B shares of the Pioneer Funds you receive in the transaction will be subject to the same contingent deferred sales charge as your Class B shares of the AmSouth Funds held at the time of sale. These shares would then convert to Class A shares eight years after the original date of purchase. Class Y shares do not impose a sales charge. 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 the 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 Pioneer Funds' transfer agent for account applications, account options forms and other account information: PIONEER INVESTMENT MANAGEMENT SHAREHOLDER SERVICES, INC. P.O.

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. 13 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 the personal identification number 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 Pioneer 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.pioneerfunds.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. The Pioneer Funds 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 with your investment firm before the New York Stock Exchange closes and your investment firm submits the order to PFD prior to PFD's close of business (usually 5:30 p.m. Eastern time), your share price will be calculated that day. Otherwise, your price per share will be calculated at the close of the New York Stock Exchange after the distributor receives your order. Your investment firm is responsible for submitting your order to the distributor. Buying Pioneer Fund Shares. You may buy shares of each 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. You can buy shares of the Pioneer Funds at the offering price. The distributor 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 must be at least $1,000. Additional investments must be at least $100 for Class A 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. Exchanging Pioneer Fund Shares. You may exchange your shares in a Pioneer Fund for shares of the same class of another Pioneer mutual fund. Your exchange request must be for at least $1,000 unless the fund you are exchanging into has a different minimum. 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. 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. Before you request an exchange, consider each Fund's investment objective and policy as described in each 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 authorized agent, and as a broker-dealer, 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. 14 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: o Are selling over $100,000 or exchanging over $500,000 worth of shares o Changed your account registration or address within the last 30 days o Instruct the transfer agent to mail the check to an address different from the one on your account o Want the check paid to someone other than the account owner(s) o Are transferring the sale proceeds to a Pioneer mutual fund account with a different registration Buying, Exchanging and Selling Pioneer Fund Shares ------------------------------------------------------------------------------------------------------ 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 transfer agent.

You are required to obtain a signature guarantee when you are: o Requesting certain types of exchanges or sales of Pioneer Fund shares o Redeeming shares for which you hold a share certificate 16 o Requesting certain types of changes for your existing account You can obtain a signature guarantee from most broker-dealers, banks, credit unions (if authorized under state law) and federal savings and loan associations. You cannot obtain a signature guarantee from a notary public. All Pioneer Funds 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. Fiduciaries and corporations are required to submit additional documents to sell Pioneer Fund shares. Exchange Limitation. You may only make up to four exchange redemptions of $25,000 or more per account per calendar year out of a Pioneer 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. Redemption Fee. Pioneer International Core Equity Fund has adopted a redemption fee on short term holdings of the Fund's shares. If you sell or exchange shares within 30 days of any purchase of Fund shares, the Fund will apply a 2% fee to the entire amount of your sales proceeds. The Fund's redemption fee 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. 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 17 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 or Class C 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." o 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. Minimum Account Size. Each Pioneer Fund requires that you maintain a minimum account value of $500. If you hold less than the minimum in your account because you have sold or exchanged some of your shares, the Pioneer Fund will notify you of its intent to sell your shares and close your account. You may avoid this by increasing the value of your account to at least the minimum within six months of the notice from the Fund. Telephone Access. You may have difficulty contacting the Pioneer Fund by telephone during times of market volatility or disruption in telephone service. If you are unable to reach the Pioneer Fund by telephone, you should communicate with the Fund in writing. Share Certificates Normally, your shares will remain on deposit with the transfer agent and certificates will not be issued. If you are legally required to obtain a certificate, you may request one for your Class A shares only. A fee may be charged for this service. Any share certificates of the AmSouth Funds outstanding at the Closing of the Reorganization will be deemed to be cancelled and will no longer represent shares of the Funds. Other Policies. Each Pioneer Fund may suspend transactions in shares when trading on the New York Stock Exchange is closed or restricted, when an emergency exists that makes it impracticable, as determined by the SEC, for the fund to sell or value its portfolio securities or with the permission of the SEC. Each Pioneer Fund or PFD may revise, suspend or terminate the account options and services available to shareholders at any time. Each Pioneer Fund reserves the right to redeem in kind by delivering portfolio securities to a redeeming shareholder, provided that the Pioneer Fund must pay redemptions in cash if a shareholder's aggregate redemptions in a 90 day period are less than $250,000 or 1% of the fund's net assets. Dividends and Capital Gains Each Pioneer Fund generally pays any distributions of net short- and long-term capital gains and dividends from any net investment income at least annually. 18 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 a Pioneer 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 Pioneer 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. Short-term capital gain distributions for each Pioneer Fund are taxable as ordinary income. Dividends from net investment income are taxable either as ordinary income or, if so designated by the 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 the maximum 15% U.S. federal tax rate. Dividends and distributions generally are taxable, whether you take payment in cash or reinvest them to buy additional Pioneer Fund shares. When you sell or exchange Pioneer 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 each Pioneer 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 Pioneer 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 and foreign tax considerations, including possible additional withholding taxes for non-U.S. shareholders. You may also consult the "Tax Status" section of each Pioneer Fund's statement of additional information for a more detailed discussion of U.S. federal income tax considerations, including qualified dividend income considerations that may affect the Pioneer Fund and its shareholders. Pioneer Funds' Rule 12b-1 Plans. As described above, each Pioneer Fund has adopted a Rule 12b-1 plan for its Class A shares, Class B shares, Class 2 shares and Class 3 shares (the "Plans"). Because the Rule 12b-1 fees payable under each Plan are an ongoing expense, over time they may increase the cost of your investment and your shares may cost more than shares that are not subject to a distribution or service fee or sales charge. Compensation and Services. Each Class A Plan is a reimbursement plan, and distribution expenses of PFD are expected to substantially exceed the distribution fees paid by the fund in a given year. Pursuant to each Class A Plan the fund reimburses PFD for its actual expenditures to finance any activity primarily intended to result in the sale of Class A shares or to provide services to holders of Class A shares, provided the categories of expenses for which reimbursement is made are approved by the board of trustees. The expenses of the fund pursuant to the Class A Plan are accrued daily at a rate which may not exceed the annual rate of 0.25% of the fund's average daily net assets attributable to Class A shares. The Class B Plan provides that the fund shall pay to PFD, as the fund's distributor for its Class B shares a distribution fee equal on an annual basis to 0.75% of the fund's average daily net assets attributable to Class B shares and a service fee equal to 0.25% of the fund's average daily net assets attributable to Class B shares. The distribution fee compensates PFD for its distribution services with respect to Class B shares. PFD also pays commissions to broker-dealers and the cost of printing prospectuses and reports used for sales purposes and the preparation and printing of sales literature and other distribution-related expenses. The plan authorizes PFD to pay a service fee to broker-dealers at a rate of up to 0.25% of the fund's average daily net assets attributable to Class B shares owned by shareholders for whom that broker-dealer is the holder or dealer of record. This service fee compensates the broker-dealer for providing personal services and/or account maintenance services rendered by the broker-dealer with respect to Class B shares. The Class 2 and Class 3 Plans (which pertain only to Pioneer Institutional Money Market Fund) provide that the fund will pay PFD, as the distributor of the shares, a distribution and service fee accrued daily and paid quarterly, equal on an annual 19 basis to 0.25% of the fund's average daily net assets attributable to Class 2 shares and 0.50% of the fund's average daily net assets attributable to Class 3 shares. These plans authorize PFD to pay securities dealers or other service organizations who agree to provide certain services to investors holding Class 1 and Class 2 shares a service fee of up to 0.25% of the fund's average daily net assets attributable to shares held by such investors. The plans also may compensate PFD for its distribution services with respect to these shares of the fund. The Class B, Class 2 and Class 3 Plans are compensation plans, which provide for a fixed level of fees. Payments under these plans are not tied exclusively to actual distribution and service expenses, and may exceed (or may be less than) the expenses actually incurred. Trustee Approval and Oversight. Each Plan was last approved by the board of trustees of each Pioneer Fund, including a majority of the independent trustees, by votes cast in person at meetings called for the purpose of voting on the Plan on December 2, 2004 (July 12, 2005 with respect to the Class 1 and Class 2 Plans for Pioneer Institutional Money Market Fund). Pursuant to the Plan, at least quarterly, PFD will provide each fund with a written report of the amounts expended under the Plan and the purpose for which these expenditures were made. The trustees review these reports on a quarterly basis to determine their continued appropriateness. Term, Termination and Amendment. Each Plan's adoption, terms, continuance and termination are governed by Rule 12b-1 under the Investment Company Act. The board of trustees believes that there is a reasonable likelihood that the Plans will benefit each fund and its current and future shareholders. The Plans may not be amended to increase materially the annual percentage limitation of average net assets which may be spent for the services described therein without approval of the shareholders of the fund affected thereby, and material amendments of the Plans must also be approved by the trustees as provided in Rule 12b-1. 20 FINANCIAL HIGHLIGHTS The following tables show the financial performance of each Pioneer Fund for the past five fiscal years and, if applicable, for any recent semiannual period (or the period during which each Pioneer Fund has been in operation, if less than five years). Certain information reflects financial results for a single Pioneer Fund share. "Total return" shows how much an investment in a Pioneer Fund would have increased or decreased during each period, assuming you had reinvested all dividends and other distributions. In the case of each Pioneer Fund, each fiscal year ended on or after the fiscal year ended June 30, 2002 has been audited by Ernst & Young LLP, each Pioneer Fund's independent registered public accounting firm, as stated in their reports incorporated by reference in this registration statement. For fiscal years prior to the fiscal year ended June 30, 2002, the financial statements of each Pioneer Fund were audited by Arthur Andersen LLP, the Pioneer Funds' previous independent accountants. Arthur Andersen ceased operations in 2002. The information for any semiannual period has not been audited. 21 Pioneer Tax Free Money Market Fund - -------------------------------------------------------------------------------- FINANCIAL HIGHLIGHTS - -------------------------------------------------------------------------------- 12/11/04 (a) to 12/31/04 CLASS A Net asset value, beginning of period $ 1.0000 -------- Increase from investment operations: Net investment income $ 0.0004 -------- Distributions to shareowners: Net investment income $(0.0004) -------- Net asset value, end of period $ 1.0000 ======== Total return* 0.04%(b) Ratio of net expenses to average net assets 0.94%** Ratio of net investment income to average net assets 1.38%** Net assets, end of period (in thousands) $ 317 Ratios with no waiver of management fees by PIM: Net expenses 1.17%** Net investment income 1.15%** * Assumes initial investment at net asset value at the beginning of each period, reinvestment of all distributions, the complete redemption of the investment at net asset value at the end of each period, and no sales charges.

INFORMATION CONCERNING THE MEETING Solicitation of Proxies In addition to the mailing of these proxy materials, proxies may be solicited by telephone, by fax or in person by the trustees and officers of your AmSouth Fund or its affiliates, including personnel of your AmSouth Fund's transfer agent, Pioneer Funds' investment adviser, Pioneer, Pioneer Funds' transfer agent, PIMSS, or by broker-dealer firms. [ ], has been retained to provide proxy solicitation services to the Funds at a cost of approximately $[ ]. Pioneer and AmSouth Bancorporation will bear the cost of such solicitation. Revoking Proxies An AmSouth Fund shareholder 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 AmSouth Fund's transfer agent, BISYS Fund Services, at P.O. Box 182733, Columbus, Ohio 43218-2733, 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 AmSouth 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 [ ], 2005 (the "record date") are entitled to notice of and to vote at the Meeting. As of the record date, the following number of shares of each AmSouth Fund were outstanding. Shares Outstanding AmSouth Fund (as of [ ], 2005) ------------ ----------------- AmSouth Capital Growth Fund ....................... AmSouth Large Cap Fund............................. AmSouth Enhanced Market Fund....................... AmSouth Value Fund................................. AmSouth Mid Cap Fund ..............................

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 a Fund is not present or if a quorum is present but sufficient votes "for" the proposals have not been received, the persons named as proxies may propose the Meeting with respect to one or more of the Funds 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 for that Fund without further notice. Any such adjournment will require the affirmative vote of a majority of the votes cast on the question 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 AmSouth Fund will set a new record date), your AmSouth Fund will give notice of the adjourned meeting to its shareholders. Telephone Voting In addition to soliciting proxies by mail, by fax or in person, your AmSouth Fund may also arrange to have votes recorded by telephone by officers and employees of your AmSouth Fund or by personnel of the adviser or transfer agent or a third party solicitation firm. The telephone voting procedure is designed to verify a shareholder's identity, to allow a shareholder to authorize the voting of shares in accordance with the shareholder's instructions and to confirm that the voting instructions have been properly recorded. If these procedures were subject to a successful legal challenge, these telephone 23 votes would not be counted at the Meeting. Your AmSouth Fund has not obtained an opinion of counsel about telephone voting, but is currently not aware of any challenge. o A shareholder will be called on a recorded line at the telephone number in the Fund's account records and will be asked to provide the shareholder's social security number or other identifying information. o The shareholder will then be given an opportunity to authorize proxies to vote his or her shares at the Meeting in accordance with the shareholder's instructions. o To ensure that the shareholder's instructions have been recorded correctly, the shareholder will also receive a confirmation of the voting instructions by mail. o A toll-free number will be available in case the voting information contained in the confirmation is incorrect. o If the shareholder decides after voting by telephone to attend the Meeting, the shareholder can revoke the proxy at that time and vote the shares at the Meeting. o [Insert touchtone telephone voting information] Internet Voting You will also have the opportunity to submit your voting instructions via the Internet by utilizing a program provided through the tabulator. Voting via the Internet will not affect your right to vote in person if you decide to attend the Meeting. Do not mail the proxy card if you are voting via the Internet. To vote via the Internet, you will need the "control number" that appears on your proxy card. These Internet voting procedures are designed to authenticate shareholder identities, to allow shareholders give their voting instructions, and to confirm that shareholders instructions have been recorded properly. If you are voting via the Internet you should understand that there may be costs associated with electronic access, such as usage charges from Internet access providers and telephone companies, that must be borne by you. o Read the proxy statement and have your proxy card at hand. o Go to the Web site listed on your proxy card. o Enter control number found on your proxy card. o Follow the simple instructions on the Web site. Please call AmSouth Funds at 1-800-624-5711 if you have any problems. o To insure that your instructions have been recorded correctly you will receive a confirmation of your voting instructions immediately after your submission and also by e-mail if chosen. o [Insert touchtone telephone voting information] Shareholders' Proposals Your AmSouth 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 the your AmSouth Fund to [ ] within a reasonable time before any meeting. If the Reorganization is completed, your AmSouth Fund will not hold another shareholder meeting. 24 Appraisal Rights If the Reorganization of your AmSouth Fund is approved at the Meeting, shareholders of your AmSouth Fund will not have the right to dissent and obtain payment of the fair value of their shares because the exercise of appraisal rights is subject to the forward pricing requirements of Rule 22c-1 under the Investment Company Act, which supersede state law. Shareholders of your AmSouth Funds, however, have the right to redeem their Fund shares until the closing date of the Reorganizations.

The undersigned officer of AmSouth Trust, after consulting with its counsel, auditors and tax advisers regarding the meaning of and factual support for the following representations, on behalf of Acquired Fund, hereby certifies and represents that the following statements are true, complete and correct and will be true, complete and correct on the date of the transaction and thereafter as relevant. Unless otherwise indicated, all capitalized terms used but not defined herein shall have the meanings ascribed to them in the Agreement. 1. Acquired Fund is a series of AmSouth Funds, a business trust organized under the laws of the Commonwealth of Massachusetts, and Acquired Fund is, and has been at all times, treated as a separate corporation for federal tax purposes. 2. As of the date of the transaction, the fair market value of the Acquiring Fund Shares received by each shareholder that holds shares of Acquired Fund (the "Acquired Fund Shares") will be approximately equal to the fair market value of the Acquired Fund Shares with respect to which such Acquiring Fund Shares are received, and the aggregate consideration received by Acquired Fund shareholders in exchange for their Acquired Fund Shares will be approximately equal to the fair market value of all of the outstanding Acquired Fund Shares immediately prior to the transaction. No property other than Acquiring Fund Shares will be distributed to shareholders of Acquired Fund in exchange for their Acquired Fund Shares, nor will any such shareholder receive cash or other property as part of the transaction. 3. Neither Acquired Fund nor any person "related" to Acquired Fund (as defined in Treasury Regulation Section 1.368-1(e)(3)), nor any partnership in which Acquired Fund or any such related person is a partner, has redeemed, acquired or otherwise made any distributions with respect to any shares of Acquired Fund as part of the transaction, or otherwise pursuant to a plan of which the transaction is a part, other than redemptions and distributions made in the ordinary course of Acquired Fund's business as a series of an open-end investment company. To the best knowledge of management of Acquired Fund, there is no plan or intention on the part of the shareholders of Acquired Fund to engage in any transaction with Acquired Fund, Acquiring Fund, or any person treated as related to Acquired Fund or Acquiring Fund under Treasury Regulation Section 1.368-1(e)(3) or any partnership in which Acquired Fund, Acquiring Fund, or any person treated as related to Acquired Fund or Acquiring Fund under Treasury Regulation Section 1.368-1(e)(3) is a partner involving the sale, redemption or exchange of any of the Acquired Fund Shares or any of the Acquiring Fund Shares to be received in the transaction, as the case may be, other than in the ordinary course of Acquired Fund's business as a series of an open-end investment company. 4. In the transaction, Acquired Fund will transfer its assets to Acquiring Fund, which will assume the Assumed Liabilities, such that immediately following the transfer, Acquiring Fund will possess all of the same assets and liabilities as were possessed by Acquired Fund immediately prior to the transaction, except for assets used to pay expenses incurred in connection with the transaction and assets distributed to shareholders in redemption of their shares immediately preceding, or in contemplation of, the transaction (other than redemptions and distributions B-1 made in the ordinary course of Acquired Fund's business as an open-end investment company) which assets constitute less than 1% of the net assets of Acquired Fund. 5. As of the date of the transaction, the fair market value of the Acquiring Fund Shares issued to Acquired Fund will be approximately equal to the fair market value of the Acquired Assets minus the Assumed Liabilities. Acquired Fund will not receive any consideration from Acquiring Fund in connection with the acquisition of the Acquired Assets other than the assumption of the Assumed Liabilities and the issuance of such Acquiring Fund Shares. 6. The Assumed Liabilities assumed by Acquiring Fund plus the Assumed Liabilities, if any, to which the transferred assets are subject were incurred by Acquired Fund in the ordinary course of its business.

Acquired Fund currently conducts its historic business within the meaning of Treasury Regulation Section 1.368-1(d)(2), which provides that, in general, a corporation's historic business is the business it has conducted most recently, but does not include a business that the corporation enters into as part of a plan of reorganization. The Acquired Fund assets transferred to Acquiring Fund will be Acquired Fund's historic business assets within the meaning of Treasury Regulation Section 1.368-1(d), which provides that a corporation's historic business assets are the assets used in its historic business. 9. Acquired Fund will distribute to its shareholders the Acquiring Fund Shares it receives pursuant to the transaction, and its other properties, if any, and will be liquidated promptly thereafter. 10. The expenses of Acquired Fund incurred by it in connection with the transaction, if any, will be only such expenses that are solely and directly related to the transaction in accordance with Rev.

AMSOUTH FUNDS on behalf of AMSOUTH [ ] FUND By: __________________________ Name: __________________________ Title: __________________________ Dated: __________, 2005 B-3 Exhibit B -- Additional Information Pertaining to Pioneer PORTFOLIO TRANSACTION POLICIES All orders for the purchase or sale of portfolio securities are placed on behalf of each fund by Pioneer pursuant to authority contained in the fund's management contract. Pioneer seeks to obtain the best execution on portfolio trades. The price of securities and any commission rate paid are always factors, but frequently not the only factors, in judging best execution. In selecting brokers or dealers, Pioneer considers various relevant factors, including, but not limited to, the size and type of the transaction; the nature and character of the markets for the security to be purchased or sold; the execution efficiency, settlement capability and financial condition of the dealer; the dealer's execution services rendered on a continuing basis; and the reasonableness of any dealer spreads. Transactions in non-U.S. equity securities are executed by broker-dealers in non-U.S. countries in which commission rates may not be negotiable (as such rates are in the U.S.). Pioneer may select broker-dealers that provide brokerage and/or research services to a fund and/or other investment companies or other accounts managed by Pioneer. In addition, consistent with Section 28(e) of the Securities Exchange Act of 1934 as amended, if Pioneer determines in good faith that the amount of commissions charged by a broker-dealer is reasonable in relation to the value of the brokerage and research services provided by such broker, the fund may pay commissions to such broker-dealer in an amount greater than the amount another firm may charge. Such services may include advice concerning the value of securities; the advisability of investing in, purchasing or selling securities; the availability of securities or the purchasers or sellers of securities; providing stock quotation services, credit rating service information and comparative fund statistics; furnishing analyses, electronic information services, manuals and reports concerning issuers, industries, securities, economic factors and trends, portfolio strategy, and performance of accounts and particular investment decisions; and effecting securities transactions and performing functions incidental thereto (such as clearance and settlement). Pioneer maintains a listing of broker-dealers who provide such services on a regular basis. However, because many transactions on behalf of a fund and other investment companies or accounts managed by Pioneer are placed with broker-dealers (including broker-dealers on the listing) without regard to the furnishing of such services, it is not possible to estimate the proportion of such transactions directed to such dealers solely because such services were provided. Pioneer believes that no exact dollar value can be calculated for such services. The research received from broker-dealers may be useful to Pioneer in rendering investment management services to any of the funds as well as other investment companies or other accounts managed by Pioneer, although not all such research may be useful to any of the funds. Conversely, such information provided by brokers or dealers who have executed transaction orders on behalf of such other accounts may be useful to Pioneer in carrying out its obligations to any of the funds. The receipt of such research has not reduced Pioneer's normal independent research activities; however, it enables Pioneer to avoid the additional expenses which might otherwise be incurred if it were to attempt to develop comparable information through its own staff. None of the funds used any brokers affiliated with Pioneer during its most recently completed fiscal year in connection with its portfolio transactions.

Portfolio Management Discussion 11/30/04 In the following interview, David Klaskin, Pioneer Oak Ridge Large Cap Growth Fund's Lead Portfolio Manager, discusses the factors that influenced performance for the twelve months ended November 30, 2004. Q: How did the U.S. stock market perform during the Fund's fiscal year? A: Stocks performed very well during the past year, as continued global growth, favorable earnings results and improving corporate balance sheets combined to form a solid foundation for the market. While stocks provided a reasonable return, their upward path was very choppy due to weakness in the second and third quarters. During this time, the market was pressured by a litany of concerns that included geopolitical tensions, soaring oil prices and rising U.S. interest rates. Investors, therefore, began to rotate into higher-quality stocks with solid fundamentals, and away from the riskier stocks that had been top performers during 2003 and the first quarter of this year. This shift was a positive for the Fund, given our focus on higher quality, fundamentally sound companies. C-3 Q: How did Pioneer Oak Ridge Large Cap Growth Fund perform? A: Class A shares of the Fund produced a total return of 11.90% at net asset value for the twelve-month period ended November 30, 2004, outpacing the 5.83% return of the Russell 1000 Growth Index. The Fund's Class A shares finished in the top 7% of the 647 funds in the Lipper Large Cap Growth Funds peer group for the one-year 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. We are pleased that the Fund has performed well both on an absolute basis and relative to its benchmark and peer group. While past performance is no guarantee of future results, of course, we believe the Fund's strong showing is the result of our disciplined investment style. Like all growth managers, we look for companies with accelerating earnings. However, we also require that two other important factors be in place. First, our research must indicate to us that an issue's earnings growth is sustainable. And second, the stocks we purchase must be reasonably valued in our view, since even fast-growing stocks can be very risky if they are purchased at too rich of a price. We believe this approach is the best way to find companies that are poised to perform well over a three- to five-year time horizon. Q: How is the Fund positioned in the two largest industry sectors in the Russell 1000 Growth Index: technology and health care? A: We added significant relative value through our approach to the technology sector, which underperformed the general market due to the prospect of slowing sales growth in 2005. In this environment, our relatively conservative positioning - i.e., our focus on reasonably valued, blue chip companies within the sector - paid off. In addition, performance was helped by the fact that technology is the Fund's largest sector underweight (a weighting below that of the benchmark). Two of the Fund's top performers in technology were Qualcomm, whose business model of earning royalties for its wireless communications technology has enabled the stock to perform well amid broader tech weakness; and Dell Computer, which continues to gain market share from its competitors. The portfolio also was helped by being underweight in the more cyclical areas within technology, such as semiconductors. In particular, our decision to avoid Intel - which underperformed by a wide margin during the period - proved to be a distinct positive for performance. Turning to health care, we added significant value through our decision to avoid the large-cap pharmaceuticals sector. Although these stocks are now as inexpensive as they were following President Clinton's attempt at sweeping health care reform in 1993, we believe there are not enough new drugs in the pipeline to make up for the lost revenues from drugs that are coming off patent protection. We looked instead for opportunities among service providers and equipment companies, such as Zimmer Holdings - a leading manufacturer of orthopedic products. Zimmer declined in the third quarter on weaker than expected earnings, prompting us to trim the position, but the stock was a strong contributor for the full year. On the negative side, the generic drug maker Teva Pharmaceuticals was one of the Fund's leading detractors. We continue to hold the stock, however, as we remain confident in its longer term prospects. Q: What other elements of the Fund's positioning affected performance? A: Energy stocks performed very well during the period, as the rising prices of oil and gas boosted profits for companies in the sector. The Fund was helped by both an overweight position and strong stock selection within the group. We received strong performance from XTO Energy, which has demonstrated the ability to manage its business effectively even during difficult times. Apache, an exploration and production company that reported record production and 57% earnings growth during the third quarter, also performed very well for the Fund. In the consumer discretionary area, the online auction company eBay provided stellar performance. eBay has emerged as a true "category killer," meaning that there is no other company that has come close to being able to establish a stronghold in its market space. While the company's fundamentals remain strong, we have begun to trim the position on the basis of its valuation. Specialty retailers such as Staples and Best Buy also contributed positively to performance. A key detractor within the consumer discretionary group was IAC/InteractiveCorp, which integrates a variety of online businesses. While we believed this would allow the company to benefit from increased online activity, the stock fell following the release of disappointing second quarter results. In the financial sector, we have gradually reduced the presence of companies that are sensitive to interest rate movements - such as traditional banks - given that the Federal Reserve is likely to continue raising rates. At the same time, we have maintained the Fund's positions in stocks with more diversified business lines that have the potential to benefit from continued strength in the economy, such as Sallie Mae and American Express. A top performer among financials was Popular, which holds a strong market position within Latin America and the fast-growing Hispanic population in the United States. Q: What is your outlook for the stock market? C-4 A: There are a number of factors that continue to work in the market's favor, including steady worldwide growth, the improvement in corporate balance sheets and companies' growing focus on dividends and share buybacks. However, the risks to market performance, which include rising interest rates and the potential for geopolitical disruptions, remain firmly in place. As a result, we think the post-bubble rally in lower-quality, higher-risk companies has likely run its course, and this should translate into a continued investor preference for higher quality companies with strong fundamentals. In this environment, we believe we can continue to add value through our disciplined, selective approach to investing. 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 funds holding more securities.

Portfolio Management Discussion 12/31/04 In the following discussion, John Carey, portfolio manager of Pioneer Fund, reviews the past year and gives an overview of Pioneer Fund's performance over that period. Q: How did the Fund perform versus its benchmark and peer group? To what do you attribute the performance? A: Pioneer Fund achieved respectable returns in 2004. Class A shares rose 11.64%, at net asset value for the calendar year. Most of the gain came in the fourth quarter, which saw the Class A shares rise 9.69%. By comparison, the Standard & Poor's (S&P) 500 Index, an unmanaged index of the general stock market, increased by 11.04% for the year and 9.23% in the fourth quarter, and the average fund in the Lipper Large-Cap Core category appreciated by 7.79% for the year and 8.86% in the fourth quarter. For the second half of 2004, the corresponding numbers were: +9.41% at net asset value for Pioneer Fund; +7.19% for the S&P 500 Index; and +5.64% for the average fund in the Lipper Large- Cap Core category. After a halting start to the year in the first half, the market performed well in the second half, and Pioneer Fund more than kept pace. 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. Looking back at our June 30 shareholder letter, we read our description of a market apparently in disarray, but with some discernible trends. Principally we noted the disappointing performance of some of the market darlings of the previous year, 2003, especially in technology, as investors during 2004 rotated into more moderately priced shares with dividends and more stable earnings. While it looked as though investors did not know what to do amidst all of their worries about rising interest rates, the war in Iraq, the weak dollar, rising oil prices, terrorist threats, and the upcoming Presidential election, they did in fact have a pretty clear idea. Seeking C-8 security in dividends and modest valuations, and also in companies likely to benefit from some of the circumstances causing their worries, investors heavily bought and drove up the prices of energy, utility, industrial, and materials stocks. The fourth-quarter rally broadened somewhat towards the end of the year, but overall, 2004 was distinctly the year of the "old economy." Many of the best-performing stocks were in industries like coal, copper, and iron-ore mining, oil and gas, railroads, steel, hotels and lodging, building materials, machinery, home construction, and ocean shipping. Our founder, Philip Carret, would have been quite comfortable in the market of 2004 because without exception all of those industries also existed, and were prospering, in the year of his birth, 1896. For Pioneer Fund, the better-than-average performance was derived both from our solid weightings in many of the old-economy stocks, especially in energy, industrials, and materials, and from our good stock selection in the four sectors that underperformed the S&P 500 average, consumer staples, financials, health care, and information technology. Among our best-performing stocks were Norfolk Southern and PACCAR in industrials and T. Rowe Price in financials, but we also benefited from having only modest relative exposure to Pfizer and Cisco Systems (which we sold during the year) and no holdings of Coca-Cola, all stocks that did poorly. We did suffer from having above-market weightings in two of the dismal semiconductor names, Applied Materials and Texas Instruments, but on the whole we managed to avoid most of the "disaster" stocks. We were particularly pleased that consumer discretionary, the sector we had highlighted in our annual report for 2003 as the "major culprit" in our relative underperformance versus the S&P during that year, was a positive contributor to Fund performance in 2004. Three of our largest gains were from stocks in that sector: McGraw-Hill, Target, and John Wiley & Sons. Q: What changes did you make to the portfolio during the second half? A: The list of 32 additions to and 10 deletions from the portfolio in the second half of 2004 makes it look as though the period was a singularly busy one for Pioneer Fund. Actually it was just a normally busy time, but due to the merger of an acquired fund, the Safeco Core Equity Fund, into Pioneer Fund during December, we ended up with some 20 new, transferred positions. Most of the Safeco fund, totaling about $700 million in assets, overlapped with positions already owned in Pioneer Fund, but we inherited the others as well. Rather than "throwing them all out with the wash," we thought that we would take our time to study them in the expectation that some might prove to be worthwhile longer-term holdings for Pioneer Fund. The merger itself marked an exciting increase to the asset base of Pioneer Fund, and also to our shareholder family. To our new, formerly Safeco fund shareholders, a hearty welcome! The total effect of the portfolio activity on sector weights was modest, with no sector weighting going up or down by as much as 2%. Materials, industrials, consumer discretionary, information technology, and telecommunications services all increased as a percentage of the Fund portfolio, and energy, consumer staples, health care, financials, and utilities all decreased. As examples, in materials we added: BHP Billiton, a major Australian-based mining and minerals company; Inco, the Canadian nickel producer; and Newmont Mining, a leading gold miner. Two new materials names came from the Safeco fund, Praxair, supplier of industrial gases, and Ball, a packaging company. Among industrials, Northrup Grumman and Ingersoll-Rand were both Safeco holdings, and in the case of consumer discretionary, five of the eight new stocks came from the Safeco fund. The two largest additions, however, were our own purchases, Nordstrom and Gap, both of them retailing companies showing signs of meaningful operational improvement over the past couple of years. Information technology rose somewhat with: our purchase of Veritas Software, which has received a merger proposal from another portfolio company, Symantec; the receipt of shares of Freescale Semiconductor from our holding Motorola; and the inclusion of EMC, an information storage specialist, from the Safeco fund. Telecommunications saw one purchase by us, Nextel Communications, and two additions attributable to the Safeco fund, CenturyTel and Verizon. Subsequent to our purchase of Nextel, the company entered into merger discussions with Sprint. In regard to the sectors where the weightings decreased, the reasons in some cases had to do with weaker relative share-price performance and in other cases with sales from the portfolio. In energy, we realized a gain on a large position in Smith International and replaced it with a smaller holding of Schlumberger. With consumer staples, despite the addition of two small positions from the Safeco portfolio, Kellogg and Kimberly Clark, the sector declined as a percent of the Fund due to underperformance versus the market averages. In the case of health care, it was a combination of selling in excess of purchasing and woeful stock performance from some of the pharmaceuticals, especially Mylan Labs, which announced an acquisition that many investors thought ill conceived. During the six months, we realized significant percentage gains on our sales of Biomet and Wellpoint Health Networks, while adding two names in the health-care equipment and supplies industry, Stryker and Medtronic, and one name in biotechnology, Amgen. Medtronic and Amgen were both from the Safeco fund. Financials saw SouthTrust stock exchanged for shares of Wachovia in a merger and our shares of Charter One Financial acquired for cash by the Royal Bank of Scotland. We sold our position in St. Paul Travelers after discouragement over the company's need to set up additional reserves following the merger creating the company. Finally, in utilities, we sold a position in Vectren and received a smaller position in Exelon from the Safeco fund. We have not listed every change, but rather have mentioned the more significant ones and summarized the impact on the portfolio. Q: What is your outlook for 2005? C-9 A: The economic outlook appears favorable over the coming year. Interest rates are expected to continue rising, but not so fast that they should present impediments to further economic growth. Earnings growth will moderate somewhat, which is normal as a business cycle lengthens, but should still be adequate to fuel additional share-price advances. Federal tax law, with the maximum 15% tax rate on qualified dividends and long-term capital gains, is likewise favorable to the stock market. Of course there are concerns, including energy and other commodity prices and the high trade and Federal budget deficits. At some point, too, investors will begin looking ahead to the next downturn in the economy and thinking about ways to position themselves more defensively. A lot rides on the length of the current business cycle. That is, will this be a "normal" cycle of four years or thereabouts, or could it become another extended cycle like the one of the 1990s, which continued for more than six years? Making the forecasting even more difficult is the unusual circumstance that this is a wartime cycle, with some economic activity not conforming to more predictable business patterns. We are somewhat inclined to the view that this will be an extended cycle, due to the excruciatingly slow start to the recovery this time around and the persisting cautiousness of many corporate managements. There generally have to be signs of "excesses" before an economy rolls over, and we are not speaking of the recent $44 million apartment sale in New York City or the advertised pricing of some luxury cars above $300,000. Rather we are speaking of excessive hiring and capital spending, leading to unneeded productive capacity, unsellable inventory, and superfluous workers, and none of that has popped up yet at least on our radar screen. So we think that we have some reasonable amount of time ahead of us for making money in the market. As always, though, we are mainly interested in companies that have the financial and management strengths to survive and do well regardless of the economic climate, and especially companies with the potential, as well as a plan and the management commitment, to do better than they have in the past. A good economy creates more opportunities for such companies to achieve improved results. Thank you very much for your interest and support.

Portfolio Management Discussion 10/31/04 Investors reacted to a variety of different influences during the 12-month period ended October 31, 2004, but the dominant trend in the market was for stock prices to move higher as the economy expanded and corporate profits grew. During the period, mid-cap stocks tended to outperform both large-cap and small-cap stocks, and value stocks outperformed growth stocks. In the following discussion, Rod Wright, leader of the team that manages Pioneer Mid Cap Value Fund, provides an update on the Fund, its investment strategies and the economic environment during the 12-month period. Q: How did the Fund perform? A: The Fund did well, outperforming the average return of competitive funds despite trailing the benchmark Russell Midcap Value Index. The Fund's Class A shares had a total return of 17.65% for the 12 months ended October 31, 2004, while Class B and Class C shares returned 16.64% and 16.60%, respectively, all at net asset value. During the same period, the Russell Midcap Value Index gained 19.74%, while the average return of the 228 funds in Lipper's Mid-Cap Value category was 15.64%. Q: What were the principal factors affecting Fund performance? A: The market began the period, in the final quarter of calendar 2003, building on the rally that had characterized much of 2003, with stock prices rising amid expectations that the economy was entering a period of sustained economic growth. The surge continued through early spring of 2004, when investors began to be concerned about a host of other influences, including high stock valuations, the instability in Iraq, political uncertainty and rapidly rising oil prices. The combination of these concerns stalled the rally until late in the period, when prices again advanced amid renewed optimism about the strength of the economy. The Fund's selections in technology, energy, consumer discretionary and telecommunications services helped support strong performance, while investments in industrials and financial services tended to detract from performance. The underperformance of the Fund, relative to the Russell Midcap Value Index, was primarily due to the absence of any investments in real estate investment trusts (REITs), part of the financial services sector. The Fund's defensive positioning in the financial services sector also held back performance, as market interest rates did not increase by as much as we had anticipated and many banks and other interest rate sensitive companies continued to perform well. C-13 Q: What were some of the individual investments that most influenced performance? A: Foot Locker, a specialty retailer focusing on athletic apparel, was a major contributor to performance, as its earnings accelerated. Transocean, the world's largest offshore oil-drilling company, posted big gains, as world oil prices advanced, stimulating drilling activity. Phelps Dodge, the world's second largest copper mining company, was another major contributor, as the prices of copper and other basic materials climbed because of surging economic growth throughout the world. Foot Locker remained the Fund's largest single holding at the end of the fiscal year, while we also continued to hold both Transocean and Phelps Dodge. Other investments that added to returns include: NCR, which develops and produces electronic processing equipment; Becton, Dickinson, a medical products company, Occidental Petroleum, an integrated petroleum company; and Providian Financial, which specializes in credit cards. The Fund still owned these stocks at the period's end. Two holdings were the subjects of acquisitions at premiums to their stock valuations, significantly helping performance. Charter One Financial, which operates banks in nine Eastern and Midwestern states, was acquired by Citizens Financial, a subsidiary of the Royal Bank of Scotland. Apogent Technologies, which produces devices and equipment for clinical and research laboratories, was purchased by Fisher Scientific International. Q: What were some of the investments that detracted from performance? A: In addition to the Fund's defensive positioning in the financial services sector and lack of exposure to REITs, performance relative to the benchmark Russell Midcap Value Index was hurt by not owning several strongly performing stocks, notably TXU, a Texas based utility, and Apple Computer. Other investments that proved to be disappointments for the fiscal year included: PMI Group, an insurer of residential mortgages and Mattel, the toy company. Q: What is your investment outlook? A: We are reasonably optimistic about the economy and investment opportunities in the stock market. The economy is expanding at a healthy rate, job growth has begun to accelerate, interest rates remain low by historical standards, and inflation continues to be restrained. Stock valuations also appear to be reasonable, giving us the opportunity to find interesting investments. Although we expect to continue to de-emphasize the stocks of companies that may be vulnerable to rapid increases in interest rates, we are moderately bullish about the overall market. Investing in mid-sized companies may offer the potential for higher returns, but these companies are also subject to greater short-term price fluctuations than larger, more established companies.

Portfolio Management Discussion 12/31/04 In the following interview, Michael Rega and Diego Franzin, co-managers of Pioneer Growth Opportunities Fund, discuss the factors that influenced performance for the twelve months ended December 31, 2004. The current portfolio team assumed the Fund's management duties on December 10, 2004. Q: What factors affected the performance of U.S. equities during the past year? A: The stock market performed very well in 2004, despite a potentially challenging environment. Investors had to contend with a host of obstacles throughout the year, including a sharp increase in oil prices, rising short-term interest rates, the uncertainty associated with the U.S. presidential election and the ongoing insurgency in Iraq. Nevertheless, the market remained well supported by its strong underlying fundamentals. The economy continued to grow at a steady pace, but not so fast that the Federal Reserve felt compelled to accelerate its measured pace of rate increases. Corporate earnings also remained robust, finishing the year at a much higher level than most analysts had anticipated. Strong earnings, in turn, translated to increased dividends and a continued improvement in corporate balance sheets. Taken together, those factors helped the stock C-16 market climb the "wall of worry" and post a double-digit gain for the year. Amid this generally positive environment, small-cap stocks outperformed their large-cap counterparts by a wide margin, reflecting the superior earnings growth of companies in the asset class. Within small-caps, value outperformed growth: for the year, the Russell 2000 Value Index returned 22.25% versus 14.31% for the Russell 2000 Growth Index. Given the Fund's focus on reasonably valued small- and medium-sized companies, the strong returns within those market segments provided a favorable tailwind to performance. 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 22.23% at net asset value during the twelve-month period ended December 31, 2004, compared to a return of 18.33% for its benchmark, the Russell 2000 Index. The Fund also outperformed the 18.38% average return of the 556 funds in the Lipper Small-Cap Core category, finishing in the top quarter of the group. 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: As new managers of the Fund, what changes do you anticipate making to the portfolio and its overall investment style? A: We do not plan to do a major rebalancing of the portfolio, but we expect to make a series of gradual changes to the Fund throughout the year as market conditions warrant. First, we intend to bring greater diversification to the portfolio by owning more stocks and taking smaller positions in individual names. Second, we plan to keep the Fund sector neutral, meaning that its industry weightings will usually be very closely in line with those of the benchmark index. In this way, the majority of the Fund's performance will be the result of individual stock selection. We believe we can add more value through company research than by attempting to predict the direction of the overall market or the relative performance of specific industries. Q: How do you intend to select stocks for the Fund? A: We start by dividing the Russell 2000 Index into a number of distinct sectors and subsectors, then we use a disciplined stock selection model to identify the most attractive stocks in each sector based on four factors: growth, quality, valuation and momentum. That enables us to analyze the entire universe of 2,000 companies and select what our criteria show to be the top 20% in each sector. Next, we focus our research capabilities to conduct a fundamental analysis of each stock that has been selected. We believe that the approach provides both breadth and depth to our stock picking. We believe that this investment style will provide more stability to the portfolio and reduce the extent of the variation in its return with respect to the benchmark index. Our goal is not to hit home runs, but to hit singles and doubles and, in the process, try to deliver market-beating returns on a long-term basis. MANAGEMENT DISCUSSION 12/31/04 (continued) Q: What is your overall view of the market at this juncture? A: We believe a focus on individual stock selection will be critical in the year ahead. Small-caps have outperformed large-caps for six years in a row, which suggests that a change in market-cap leaders may be in order. What's more, our analysis shows that on a historical basis, growth stocks have been this inexpensive in relation to value less than 5% of the time. This has two implications: first, it means that gains in the small-cap value area are not likely to come as easily as they did in 2004. As a result, fundamental research should play a very important role in generating outperformance. Second, it means that in assessing the outlook for individual stocks, we will place a higher than normal emphasis on companies with the most attractive growth characteristics. We believe these steps will help the Fund effectively navigate the year ahead even in the event that the stellar relative performance of the small-cap value asset class begins to cool off. Q: In what areas are you finding the best investment opportunities? A: In 2004, every major sector in the Russell 2000 Index provided double-digit returns with the exception of technology. We expect a greater dispersion of returns in 2005, which again would work to our advantage as individual stock pickers. We will be looking for opportunities in technology and health care, two areas that underperformed the broad-based index during 2004. One of the Fund's top holding, MICROS Systems, is a tech stock that in our view is among those that have additional upside. MICROS develops and markets software applications to the hospitality industry, mostly table service restaurants. Their software allows restaurants to improve coordination between servers and kitchen staff and reduce costs by improving inventory C-17 management and product reordering. A key driver of future growth is expansion into the hotel industry as the industry embarks on a 5- to 7-year technology infrastructure upgrade cycle. Within health care, we will be closely looking for opportunities in the biotechnology sector. We believe biotechs are less risky than in the past, since there are more companies that have been public for four or five years and, therefore, have a longer earnings history and more experienced management teams. We will look to capitalize on companies we identify as quality managed and staffed, along with a proven record of execution. On the other side of the coin, we find the consumer staples and real estate areas to be less compelling. And within financials, we intend to focus on companies that have an asset/liability mix that favors a flattening yield curve environment and exposure to expanding markets such as Florida and Texas. Q: Do you have any final thoughts for investors? A: We believe that the most important aspect of asset management is individual stock selection, and we will remain committed to our research-driven approach. Regardless of the direction of the overall market, we believe Fund shareholders have the potential to benefit from our efforts to identify the highest-quality small-cap stocks in the market. By concentrating on one industry or on a group of related industries, the portfolio is more susceptible to adverse economic, political or regulatory developments affecting those industries than is a portfolio that invests more broadly. Investing in foreign and/or emerging markets securities involves risks relating to interest rates, currency exchange rates, economic, and political conditions. Investing in small companies may offer the potential for higher returns, but these companies are also subject to greater short-term price fluctuations than larger, more established companies.

Portfolio Management Discussion 1/31/05 In the following interview, portfolio manager Peng Chen, Chief Investment Officer for Ibbotson Associates, discusses the market environment and investment strategies that applied to the three portfolios in the Pioneer Ibbotson Allocation Series for the period of almost six months since they began operations on August 9, 2004. Q: Could you characterize the economic backdrop against which the three portfolios began investment operations? A: The period of nearly six months between the August 9, 2004 launch of the funds and the end of January 2005 was an uncertain environment for investors. While the U.S. economy has continued the growth trend that started in the second half of 2003, the rate of growth has showed signs of decelerating. At the same time, inflation continues to be a concern, spurred on by the continued strength in the economy and, to a lesser extent, by oil prices that have been at all-time highs. On the interest rate front, the Federal Reserve began to raise short-term rates earlier in 2004 and appears to be maintaining a tightening policy to keep economic growth in check. Q: How did the financial markets respond in this climate? A: Early in the period, equity market levels wavered while basically staying within a range. As the November 2 date for the U.S. presidential election drew closer, however, investors became increasingly focused on the accompanying uncertainties, and C-20 stocks fell. In contrast, bond prices generally showed strength during this time. The trends appeared to reverse themselves in the aftermath of the election. The stock market responded positively to the increased clarity, while bond market performance was dampened by expectations of a continued lack of progress on reducing federal budget deficits. Q: What were the strategic considerations that you applied to the three portfolios in allocating assets? A: As the three portfolios in the series were launched and initial investor dollars were received, assets were invested in keeping with the respective broad asset allocation and specific mutual fund targets established prior to the launch of the series. Toward the, middle of the period, in late October, we implemented two strategic changes across all three portfolios. First, within the U.S. stock portion of the portfolios, we implemented a moderate emphasis on value stocks and a corresponding underweighting of more growth-oriented investments. We did this because we believe the U.S. economy has entered into a decelerating growth cycle that should favor value equities with relatively stable earnings prospects. We also believe that the potential for higher inflation and interest rates favors the value investment style over growth. Our equity valuation and momentum models further support this assessment, indicating an overweighting of value and an underweighting of growth equities. That said, value stocks have now outperformed growth over a period of more than four years. If the economy starts to show signs of more rapid growth, an overweighting of more growth-oriented investments will be warranted. With respect to the other equity asset classes, the portfolios' targeted exposure across large-, mid-, and small-cap equities remained unchanged. We have also maintained neutral target weightings in the non-U.S. equity market alternatives, both developed and emerging. The other shift has been within the bond portion of the portfolios, where we implemented an underweighting of the long-term bond vehicle, with the difference allocated to the shorter-term fixed income alternative. We believe that, given the prospect of higher interest rates across all maturities, but especially on the long end of the yield curve, shorter duration fixed-income investments are more attractive. Elsewhere within fixed-income, we have maintained neutral positions in the high yield bond offering, as well as in the non-U.S. fixed-income option. Going forward, we will closely monitor economic indicators and interest rate movements to evaluate whether we need to make any adjustments to the views underlying these allocations. Given the significant level of uncertainty that continues to impact the financial markets, we believe that maintaining appropriate diversification across asset classes will be especially important in the months ahead.

Portfolio Management Discussion 12/31/04 As the domestic economy showed evidence of a sustained recovery during the second half of 2004, the U.S. Federal Reserve continued to raise short-term interest rates gradually to contain the risk of inflation and keep the economy in check. The fixed-income market reacted favorably to the Fed's series of measured increases in the Fed funds rate, with the yields of longer-term Treasuries actually declining modestly. Meanwhile corporate bonds and mortgages continued to outperform Treasuries as investors sought out higher-yielding investments in an environment of low, by historical standards, interest rates. In the following discussion, Kenneth J. Taubes discusses the factors that influenced Pioneer Bond Fund's performance during the six months. Mr. Taubes, Director of Pioneer's Fixed Income Group, oversees the team responsible for daily management of the Fund. Q: How did the Fund perform during six months ended December 31, 2004? A: Pioneer Bond Fund performed well, outpacing its benchmark as well as the competitive funds average. For the six-month period, the Fund's Class A shares returned 4.92%, at net asset value. During the same six months, the Lehman Brothers Aggregate Bond Index returned 4.18%, while the average total return of the 224 funds in Lipper's Corporate Debt A-Rated Bond Fund category was also 4.18%. On December 31, 2004, the standardized 30-day SEC Yield on Class A shares was 4.00%. 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 factors affected Fund performance? C-30 A: During a period in which investors sought out yield, the Fund held to its emphasis on sectors with yield advantages over Treasuries, corporate bonds and mortgage-backed securities. Both corporate bonds and mortgage securities outperformed Treasuries, with high-yield corporate securities turning in the best performance of all sectors of the domestic bond market. Despite rising short-term rates, the yields of longer maturity Treasuries were relatively stable, and investors sought out securities with yield advantages over Treasuries. Against a backdrop of a strengthening economy, corporations generated additional cash flow, which improved the overall credit quality of corporate securities and further encouraged investments in both high-yield and investment-grade corporate debt. Our emphasis on high-yield and investment-grade corporate bonds as well as mortgage securities helped support Fund performance throughout the six months. At the end of the six-month period, about 55% of assets were invested in mortgage securities and about 40% were invested in corporate debt, including almost 15% high-yield bonds. We reduced our high-yield positions slightly in the final quarter of the year. As we did so, we increased our investments in mortgages, which offered yields competitive with investment-grade corporates but with higher quality. Overall average credit quality of the portfolio was raised slightly during the period from A to A+. Less significant but also helpful was our decision to keep the Fund's sensitivity to interest-rate changes -- as measured by duration -- either neutral or slightly longer than the benchmark Lehman Brothers Aggregate Bond Index. In an environment of stable to slightly-declining market interest rates, this strategy tended to benefit performance. On December 31, 2004, the Fund's average effective duration was a somewhat shorter 3.99 years. Q: What were some of the individual holdings that most influenced portfolio performance? A: Among the high-yield holdings that helped performance were the bonds of two steel companies: International Steel, which we sold to take profits before the period ended, and ISPAT Inland ULC, which were upgraded in credit rating after the company was acquired by a Dutch corporation. Other bonds which appreciated strongly in price were those of financial service corporates Allmerica Financial, E-Trade and Odyssey Re. Detracting from results were insurance company Provident, whose bond prices slipped amid controversy over the New York attorney general's investigation of industry practices, Toys "R" Us, which announced restructuring plans, and Intelsat, a satellite company that withdrew plans for an initial public stock offering. Q: What is your investment outlook? A: We anticipate that the Federal Reserve will continue to raise the Fed funds rate at a gradual pace during 2005. The fixed-income market already has anticipated, in current bond prices, a series of further increases that would bring the Fed funds rate from 2.25% to near 3.5% by the end of the year. We believe the market rates of longer-term and intermediate-term securities already are close to being fairly valued. As a result, we anticipate that the yield curve -- which measures the relationship between short-term and longer-term interest rates -- likely will flatten during the year as short-term rates move up. In general, valuations of corporate securities appear relatively high by historical standards, but they probably are justified given the strong economic fundamentals both in the United States and throughout the globe. Strengthening economies are now helping companies across all sectors, resulting in improved cash flows and corporate profits. In this environment, we think corporate bonds should perform well, consistent with their yield advantage over Treasuries. As a result, we will continue to look for opportunities in the corporate sector. However, we expect to also put greater emphasis on mortgage securities, which offer virtually the same yields as investment grade corporate debt but have the advantage of higher credit ratings. Investments in high yield or lower-rated securities are subject to greater-than average risk. 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. 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. 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.

Portfolio Management Discussion 12/31/04 During a period when interest rates remained relatively low, Pioneer Tax Free Income Fund's exposure to investments in a variety of states and a diverse number of economic sectors provided an attractive level of tax-free income. In the following interview, David Eurkus, a member of Pioneer's Fixed Income Management Team, discusses some of the factors that had an impact on the municipal bond market and your Fund. Q: How did the Fund perform? A: For the 12-month period ended December 31, 2004, Pioneer Tax Free Income Fund's Class A shares produced a 4.75% total return at net asset value. The Fund's benchmark, the Lehman Brothers Municipal Bond Index, returned 4.48%, and the average return of the 297 funds in the Lipper General Municipal Debt Funds Category was 3.70%. Lipper is an independent monitor of mutual fund performance. The Fund's Class A shares generated a 30-day SEC tax-free yield of 3.88% on December 31, 2004. That translates into a taxable equivalent yield of 5.97%, based on the maximum federal income-tax rate of 35%. 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: Early in the period, the strength of the economic rebound raised concerns that inflation and interest rates might rise. In this environment, there was a significant decline in the bond market, which pushed bond prices down and yields up. As the fiscal C-34 year progressed, however, reports associated with the economy indicated that the rapid pace of growth had shifted to a slower but steady rate. Despite this slight softening in the economic expansion, the Federal Reserve began tightening monetary policy, boosting the Federal funds rate on five occasions, each time by 0.25%. By yearend, the Federal funds rate was 2.25%, up from 1.00% at the start of 2004. (The Federal funds rate is the rate banks charge each other for overnight loans.) Initially, the Fed's actions caused yields to move higher, but when it appeared that inflation was under control, the yield curve flattened. (The yield curve shows the relationship between bond yields and maturity lengths.) With a flatter yield curve, short-term yields moved higher and prices declined; and longer-term yields fell or remained stable, boosting bond prices. Q: How did you manage the Fund in this environment? A: We maintained a diverse portfolio with assets invested in 154 securities in 38 states. We continued to emphasize sectors that are vital to the growth of the U.S. economy. These sectors included health care/hospitals, housing, transportation, and power and energy, areas in which the underlying credit quality of the fixed-income securities tends to improve as the economy gets stronger. We also had a position in tobacco revenue bonds, which are investment-grade securities that are backed by the tobacco settlement money awarded to states. Most of the portfolio was invested in investment-grade securities, those rated BBB or better. However, about 10% was allocated to below investment-grade bonds, which had relatively high yields and which enhanced the Fund's income stream. At the end of the period, the Fund's overall quality rating was A+. Q: What contributed most to performance? A: As short-term interest rates went up, the portfolio benefited from the price appreciation that resulted from the declining yields on longer-term securities. In addition, the below investment-grade bonds in the portfolio helped boost the tax-free income and prices. Q: What detracted from performance? A: There were no significant detractors. Overall the portfolio was positioned for declining interest rates. Our duration could have been somewhat longer; however, it exceeded the duration of our benchmark, the Lehman Brothers Municipal Bond Index, and our peer group, the Lipper General Municipal Debt Funds Category. (Duration measures a bond's sensitivity to interest-rate changes. A shorter duration is helpful when interest rates rise, and a longer duration is usually an advantageous when interest rates decline.) Q: What is your outlook for the next six months? A: We believe that the economy is on a positive growth path and expect the Fed to continue making modest interest-rate hikes over the near term. Therefore, we expect short-term rates to move higher and long-term rates to remain stable or possibly decline. In this environment, income could become a larger component of performance. A portion of income may be subject to state, federal, and/or alternative minimum tax. Capital gains, if any, are subject to a capital gains tax. A portion of income may be subject to state, federal, and/or alternative minimum tax. Capital gains, if any, are subject to a capital gains tax. 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. If the Internal Revenue Service determines an issuer of a municipal security has not complied with applicable tax requirements, interest from the security could become taxable and the security could decline significantly in value. 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.

Portfolio Management Discussion 12/31/04 As the U.S. economy expanded, the Federal Reserve began raising interest rates at a slow but steady pace. Short-term interest rates rose more than long-term rates, which remained virtually unchanged for the year. For example, at the beginning of the year, the yield on the two-year Treasury was 1.82%. At the end of the year, it was 3.07%. The yield on the 10-year Treasury began the year at 4.25% and ended the year at 4.22%. Against this backdrop, investors in U.S. Government and agency securities were rewarded with a relatively attractive level of income during the 12-month period ended December 31, 2004. In the interview below, Richard Schlanger, a member of the Pioneer fixed-income team, discusses the factors that affected the fixed-income market and the Trust over the past 12 months. C-37 Q: How did the Trust perform during the period? A: For the 12-month period ended December 31, 2004, Class A shares of Pioneer America Income Trust produced a total return of 2.77% at net asset value. The Trust underperformed its benchmark, the Lehman Brothers Government Bond Index, which returned 3.48% for the same period. The Trust also underperformed the Lehman Brothers Fixed-Rate Mortgage-Backed Index, which returned 4.70%. We attribute the shortfall relative to the Lehman Brothers Fixed-Rate Mortgage-Backed Index to the index's significant exposure to securities issued by the Federal Home Loan Mortgage Corporation (Freddie Mac) and the Federal National Mortgage Association (Fannie Mae), which outperformed Ginnie Maes. Because conventional mortgages--those issued by Freddie Mac and Fannie Mae--do not have the backing of the full faith and credit of the U.S. Government, we do not invest in them. The Trust underperformed the 3.19% return generated by the General U.S. Government 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 3.25%. 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. The economy continued to gain strength in 2004, reflected by improving job growth, relatively strong consumer spending, and higher commodity and oil prices. With the economy on a firmer footing, the Federal Reserve boosted short-term interest rates in June and continued raising them through the end of the year. By year-end, the federal funds rate was 2.25%, up from 1.00% at the start of 2004. (The federal funds rate is the rate banks charge each other for overnight loans.) Initially, the Fed's actions caused Treasury yields to move higher but when it appeared that inflation was under control, the yield curve flattened. The yield curve shows the relationship between bond yields and maturity lengths. With a flatter yield curve, short-term yields moved higher and prices declined; longer-term yields fell or remained stable, boosting prices. An enormous amount of Treasury buying by overseas investors was also instrumental in keeping Treasury yields low. Foreign central banks had large cash reserves, which they invested at record levels in the U.S. Treasury market in an attempt to stem the decline of the U.S. dollar relative to their own currencies. Q: How did you manage the Trust in this environment? A: The Trust was divided between mortgage-backed securities, which accounted for 70.6% of net assets, and Treasury securities, which composed 28.2% of net assets. The Trust also had a 1.2% cash position. In the mortgage market, we invested in securities issued by the Government National Mortgage Association (GNMA), which are backed by the full faith and credit of the U.S. government. (A full faith and credit backing applies to underlying Trust securities, not to Trust shares). Because interest rates remained attractive and the housing market was strong, we sought to avoid prepayment risk. When interest rates decline, homeowners often "prepay" their existing mortgages and refinance their homes at a lower rate. Significant prepayment activity can result in declining yields and share prices in portfolios with investments in mortgages. To mitigate this risk, we favored mortgages with low loan balances that were not likely to be refinanced. We also emphasized mortgage pools in slow-paying states, such as New York and Texas, where the rate of housing turnover is relatively low in comparison to other states. In addition, we sought mortgages with coupons (stated rates of interest) in the 4.5% to 5.5% range, which would probably not be refinanced quickly. In the Treasury portion of the Trust, we emphasized securities with short to intermediate durations. We expected yields to move higher and wanted to minimize the price volatility that would naturally occur as yields rose. Therefore, we kept duration shorter than the benchmark. Measured in years, duration measures a bond's price sensitivity to interest-rate changes. A shorter duration can protect a portfolio from price declines as yields rise. We were premature, however, in our expectation of higher yields. As a result, our short-duration strategy worked against the Trust. Long-term Treasuries outperformed, because of the huge demand from overseas investors and the flattening of the yield curve. For example, the 30-year Treasury bond returned 8.89%; the five-year Treasury returned 2.39%. Q: What contributed most to performance? A: The significant overweight in mortgage-backed securities made the largest positive impact, as mortgages outperformed other fixed income assets. Minimizing prepayment risk by selecting specific mortgage pools also helped drive performance. The flatter yield curve, which boosted the prices of longer-term Treasury securities, also benefited results. Q: What detracted from performance? C-38 A: The Trust's underweight in long-term Treasuries. We continue to believe, however, that yields on such Treasuries are artificially low, given the weak U.S. dollar, the growing trade imbalance and a Fed that is likely to continue raising interest rates. Q: What is your outlook for the next six months? A: In the short term, we expect the investment environment to remain unchanged and are unlikely to alter the Trust significantly during the first quarter of 2005. We plan to continue to emphasize mortgage securities. In February, Federal Reserve Chairman Alan Greenspan will make his semi annual Humphrey-Hawkins testimony before Congressional committees. At that time, we will learn what to expect in the way of Fed interest-rate policy and what the central bank's thinking is about the prospects for accelerating inflation. Whenever the Fed raises rates, there is a lag effect; and it can take as long as a year for higher rates to affect the economy. Over the next several months, we will be closely monitoring data to determine the appropriate action to take should the economic backdrop change. Government guarantees apply to the underlying securities only and not to the prices and yields of the portfolio. 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. 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. 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.

Portfolio Management Discussion 2/28/05 In the following interview, Richard Schlanger, the Fund's Lead portfolio Manager, discusses the factors that influenced performance for the semiannual period ended February 28, 2005. Q. How would you characterize the market environment for fixed- income investors over the six-month period? A. On balance, the economy continued to show evidence of solid growth, although some of the employment statistics have not been as robust as in past recoveries. Given this backdrop, the Federal Reserve continued to execute a "measured" approach to removing its accommodative stance with respect to short-term interest rates. This took the form of three separate hikes in the benchmark fed funds rate (the interbank overnight lending rate) totaling three-quarters of a percentage point over the period. While long-term interest rates were relatively stable, shorter-term bonds experienced yield increases - and corresponding price declines - over the period. Yields on shorter-maturity issues rose substantially over the period, with both the six-month and two-year Treasuries experiencing yield increases of just over one percentage point. By contrast, long-term interest rates ended the period only slightly higher than where they began, with the ten-year Treasury yield increasing approximately one-quarter percentage point. Q. How did the Fund perform in this environment? A. The Fund's total return from August 31, 2004, through February 28, 2005 was a positive 0.12%, versus -0.16% for the unmanaged benchmark index, the Lehman Brothers One-to Three-Year Government/Credit Index. The return number is for Class A shares and does not include the impact of any sales charge paid. Call 1-800-225-6292 or visit www.pioneerfunds.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 Pioneer Short Term Income Fund principal value will fluctuate, and shares, when redeemed, may be worth more or less than their original cost. The Fund also continued to deliver good income. The 30-day SEC yield for Class A shares on February 28, 2005, was 2.47%. This yield reflects the waiver of certain expenses by the investment advisor; without the waiver, the 30-day SEC yield for Class A shares would have been 1.99%. The Fund's absolute return for the six-month period primarily reflects a difficult environment for short-term bonds, as yields increased and prices generally fell among these issues. We believe the Fund's comparatively better performance versus its benchmark index can be attributed to a combination of: 1. shorter overall portfolio duration - a measure of interest rate sensitivity - which helped cushion against pervasive price declines; C-43 2. security selection favoring mortgage pass-through securities, an area of the bond market that outperformed Treasury securities. Q. What is your outlook? A. We continue to believe that, despite some underlying strain, the global economy is on a path of solid growth, led by the United States, which appears positioned to deliver GDP growth in the 3.5% to 4.0% range for the near-to-intermediate term. Growth at this level would support solid expansion in employment over time and could put some upward pressure on inflation and interest rates. In addition, the decline of the U.S. dollar and continued high oil prices both suggest that a rise in inflation would not be surprising, with a corresponding impact on interest rates. Finally, the lack of progress in reducing the U.S. budget deficit may also lead to rising interest rates over time. With respect to short-term rates, we expect the Fed to continue on a course to raise rates gradually over the next year or so in an effort to contain potential inflationary pressures while allowing the economy to continue on its current growth path. Q. How is the Fund currently positioned? A. In view of our outlook for continued solid economic growth, the Fund is somewhat conservatively positioned from the perspective of sensitivity to changes in interest rates. At the end of February, the Fund's weighted average maturity was 1.38 years, well under the Fund's maximum of three years. Average quality of the Fund's portfolio is currently a high "AA." We continue to maintain broad exposure to a number of areas of the bond market, while seeking to identify and benefit from relative value among sectors. Currently, yield differentials are quite narrow among sectors on the short end of the curve. For instance, high-quality corporates offer less than half of a percentage point of additional yield versus Treasuries of comparable maturity. At the end of February, our weighting in corporate bonds accounted for about 22% of Fund assets, at the low end of our anticipated range. Nearly 35% of the Fund's assets are invested in mortgage pass-through securities, down from approximately 40% at the beginning of the period, again reflecting our view on relative value. Our holdings among pass-throughs are focused on "balloon" mortgages with shorter maturities, as well as collateralized mortgage obligations that we believe carry low risk of experiencing a slowing of prepayments (and corresponding increase in duration. U.S. Treasury issues totaled about 32% of assets at period end, including a small position (approximately 3.7%) in short-term "STRIPS" or "zero coupon" bonds. STRIPS are purchased at a discount to face value and redeemed at par value upon maturity, and the position is anticipated to provide an additional measure of support for the Fund's share price. Going forward, we will continue to seek to provide a high level of current income while maintaining a relatively stable share price. While the Fund's share price will fluctuate, our focus on shorter-term bonds is designed to reduce price volatility in comparison to longer term alternatives. We believe the Fund's high quality and limited exposure to interest-rate changes makes it an attractive option for investors seeking to maintain important fixed-income exposure in an uncertain environment. Investing in foreign and/or emerging markets securities involves risks relating to interest rates, currency exchange rates, economic, and political conditions. 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.

Portfolio Management Discussion 12/31/04 Although the U.S. Federal Reserve started to raise short-term interest rates from the lowest levels reached in more than four decades, 2004 remained a year in which money market investments offered extremely low yields by historical measures. Despite five increases in interest rates between June 30 and December 31, the key Fed Funds Rate ended the year at just 2.25%. Throughout the 12 months ended December 31, 2004, Pioneer Cash Reserves Fund maintained a $1 share price and provided modest income consistent with the yields available in the money market. The Fund invests exclusively in high quality money market instruments issued by the U.S. government and domestic corporations and banks. All issues have the highest ratings from the two nationally recognized ratings organizations: A1 by Standard & Poor's Investors Services and P1 by Moody's Investor Services. (Ratings apply to underlying securities, not Fund shares.) In the following discussion, Andrew D. Feltus reviews the investment environment and the strategies that affected Pioneer Cash Reserves Fund over the 12 months ended December 31, 2004. Mr. Feltus is a member of Pioneer's Fixed Income Group, which is responsible for the daily management of the Fund. Q: How did the Fund perform during 2004? A: For the 12 months ended December 31, 2004, Class A shares of Pioneer Cash Reserves Fund had a total return of 0.45%, at net asset value. On December 31, 2004, the Fund's seven-day effective yield for Class A shares was 1.13%. For the 12 months, the average total return among the 395 funds in Lipper's Money Market Fund category was 0.60%. 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 year? A: For virtually the entire first half of 2004, the influential Fed Funds Rate remained at a 46-year low of 1.00%. The situation began to change when the Federal Reserve raised the rate on June 30 by one-quarter of one percentage point and signaled that it intended to initiate further increases on a gradual basis. The central bank raised the rate four more times, and the Fed Funds Rate stood at 2.25% at the end of the year. The rate increases occurred against a backdrop of continued economic growth and hints of an increase in inflationary pressure. Economic growth, as measured by growth in Gross Domestic Product (GDP), rose by an average annualized rate of 4.6% during the first nine months of 2004. Affected by the higher costs of energy, the Consumer Price Index rose to about 3.5% by the end of November. While periodic concerns about low new-job creation did arise, in general the Federal Reserve Board believed that the economy was gathering enough strength that monetary policy could be tightened to avert the possibility of increasing inflationary threats. At the end of the year, the Federal Reserve was widely expected to continue to raise short-term rates further in 2005. Q: What were your principal strategies in this low-interest rate environment? A: We held to our commitment to high quality money market instruments. We started gradually to lower the Fund's effective duration so that we could take advantage of higher yields available as the Federal Reserve Board proceeded with its rate increases. At the end of the year, the effective duration of the Fund was 60 days, and we were moving to have a target duration of about 45 days as the new year unfolded. Q: What is your investment outlook? A: We anticipate that the economy will show sustained growth in 2005 and that the Federal Reserve Board will maintain its policy of raising short-term grates gradually. At the same time, because of budget pressures and concern about the federal deficit, the government is likely to put new brakes on spending. The combination of the tighter monetary policy and restrained fiscal policy may act as a drag on the pace of economic growth and ultimately cause a possible change in monetary policy. If economic growth does begin to slow, the Federal Reserve may revise its current bias toward raising short-term rates. However, until that appears to be imminent, we intend to continue to keep the Fund's effective duration relatively short to enable us to invest in newer, higher-yielding securities that have the potential to raise the level of income to be distributed to C-46 shareholders. Investing in foreign and/or emerging markets securities involves risks relating to interest rates, currency exchange rates, economic, and political conditions.

Portfolio Management Discussion 12/31/04 On August 2, 2004, Pioneer Investments assumed management of the former Safeco Funds. In the following interview, David Eurkus, a member of the fixed income team, details the investment environment for tax-free money funds during the 12-month period ended December 31, 2004, the Fund's performance for the period, and the Fund's portfolio strategy going forward. Q: Will you describe what, if anything, has changed and what has remained the same in the transition of Fund management to Pioneer? A: As a Safeco product, and now as Pioneer Tax Free Money Market Fund, this has been and will continue to be a very conservative offering. We are keeping the Fund as a high quality, liquid product. We will not compromise stability of principal in any way by taking on additional risk to secure a more competitive yield than our peers. Safety of principal is paramount and, as part of the objective, we will continue to seek tax-free income for the Fund's shareholders. C-48 Q: How did the Fund perform during its most recent fiscal year? A: For the 12-month period ended December 31, 2004, the Fund's Class A shares posted a 0.58% total return at net asset value. (The performance of each class of the Fund is the performance of the predecessor fund's Investor Class, which has been restated to reflect differences in any applicable sales charges (but not Rule 12b-1 fees or other differences in expenses). If all the expenses of the Pioneer fund were reflected, the performance would be lower.) In comparison, the Lipper Tax-Exempt Money Market Average returned 0.56%. 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 money funds during the time period? A: Prior to June 2004, short- and long-term interest rates had continued to fall since the stock market bubble burst in 2001. Early last year, one-year tax-free money market rates fell as low as 0.50%. Then, as the U.S. economy began to show modest improvement in the first half of 2004, the Federal Reserve indicated that the economy and job growth were showing signs of improvement and that the Fed was becoming more concerned about the possibility of rising inflation rather than deflation. The Fed also hinted that it would begin to raise short-term interest rates in the second half of 2004, but at a "measured" pace. The Fed then raised short-term interest rates by 25 basis points at each of its five meetings in the second half of the year. As a result, the one-year Bond Buyer Index, the market's measurement of tax-exempt money market rates, rose from 0.50% at the start of the year to 1.25% at year end. Historically, those are still extremely low rates. Supply and demand for tax-exempt money market securities continue to be well balanced. This is evidenced by the still significant amount of assets being held in taxable as well as tax-free money market funds. Investor demand continues to be substantial, and there is ample supply to deal with the asset base. Q: What has been your strategy since assuming management of the Fund last August? A: We continue to maintain broad diversification, both on a regional and national basis, with AAA credits in revenue as well as general obligation issues. As a Seattle-based fund, the previous Safeco product was regionally focused, with investments based in Colorado, Texas and Alaska as its top three portfolio concentrations. As we continue to emphasize safety of principal we will be changing to a more nationally focused diversification strategy. The Fund invests in floating rate securities (55% of portfolio assets as of December 31, 2004) as well as fixed-rate instruments (45% of assets). The interest rate of floating rate securities adjusts periodically based on indices such as the Bond Buyer Index and the Fed funds rate. As of December 31, the Fund's effective maturity was 56 days. With the Fed's series of short term interest rate increases, the yield curve is changing, and we will adjust the portfolio accordingly. As some six- and 12-month securities in the portfolio mature we are converting them to cash in anticipation of further short-term interest rate increases. That will gradually decrease the Fund's weighted average maturity in the short term. Over the long term this strategy should benefit shareholders because we will be reinvesting at higher rates than the yields that are currently available. In terms of portfolio quality, over 90% of the portfolio is AAA-rated, with the balance rated AA. (Ratings apply to underlying securities, not Fund shares.) Q: What is your outlook? A: In the months ahead, we foresee continued modest growth in the U.S. economy. We also think that the Fed will maintain its bias for measured increases in short-term interest rates over the next several months. A portion of income may be subject to state, federal, and/or alternative minimum tax. Capital gains, if any, are subject to a capital gains tax. Investing in foreign and/or emerging markets securities involves risks relating to interest rates, currency exchange rates, economic, and political conditions. 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. Although the Fund seeks to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in the Fund.

Sullivan, CFA Director, Value Equity Strategies AmSouth Bank AmSouth Asset Management, Inc. Brian Sullivan has been the portfolio manager for the AmSouth Value and AmSouth Balanced Fund since June 2004. Mr. Sullivan has more than 18 years of investment management experience and holds an MBA in finance and a bachelor's degree in economics. INVESTMENT CONCERNS Value-based investments are subject to the risk that the broad market may not recognize their intrinsic value. Equity securities (stocks) are more volatile and carry more risk than other forms of investments, including investments in high-grade fixed income securities. The net asset value per share of this Fund will fluctuate as the value of the securities in the portfolio changes. - -------------------------------------------------------------------------------- PORTFOLIO MANAGER'S PERSPECTIVE "The AmSouth Value Fund uses a 'value investing' approach. Rather than pursue hot stocks that are in high demand, we search for solid companies with good fundamentals that are available that attractive prices. By adhering to this investment approach through entire market cycles, we seek to achieve above average long-term results with less volatility than the overall market." - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- Q & A Q. How did the Fund perform during the six-month period ended January 31, 2005? A. The Fund delivered a total return of 11.37% (Class A Shares at NAV. Had the effects of the front-end sales charge been included, the return would have been lower). That compared to a 10.47% total return for the Fund's benchmark, the S&P 500/BARRA Value Index.(1) The Fund's total return does not reflect the deduction of a sales charge on Class A Shares. If reflected, the sales charge would reduce the performance quoted. With the maximum sales charge of 5.50% and recurring fees, the Fund's six month, 1 Year, 5 Year and 10 Year average annual total returns for the period ended January 31, 2005, were 5.27%, 4.36%, 1.77% and 9.18%, respectively, for Class A Shares. The returns quoted assume the reinvestment of dividends and capital gains distributions. Past performance does not guarantee future results. The performance data quoted represents past performance and current returns may be lower or higher. Total return figures include change in share price, reinvestment of dividends and capital gains and does not reflect the deduction of taxes that a shareholder would pay on distributions and redemptions. The investment return and principal value will fluctuate so that an investor's shares, when redeemed may be worth more or less than the original cost. For performance data current to the most recent month end please visit www.amsouthfunds.com. Q. What factors affected the Fund's performance? A. A favorable backdrop, characterized by economic growth, the resolution of the presidential election and a pullback in oil prices, helped stocks rally during the fourth quarter of 2004. Value stocks performed particularly well, boosting this Fund's returns Stock selection produced the largest contribution to the Fund's relative performance. Strong performance by particular stocks in the restaurant and retail industries helped the Fund's consumer- discretionary stocks outperform the corresponding sector in the index. 2 The Fund's relative returns also benefited from our strategy in the energy sector whereby we reduced the Fund's energy holdings during the period as prices on energy stocks increased. That strategy boosted performance against the benchmark, as energy stocks declined late in the period in response to falling oil prices. + The Fund held an underweight position in utilities stocks during the period. That stake weighed slightly on relative returns, as utilities stocks led the benchmark. The reverse was true for performance data quoted represents past performance telecommunications services stocks. We over-weighted that sector, and current returns may be lower or higher. Total return so its relatively weak performance modestly reduced the Fund's figures include change in share price, reinvestment of return relative to the returns of the benchmark. + + The Fund's portfolio is current to January 31, 2005 and subject to change.

They also serve as the portfolio managers for the AmSouth Enhanced Market Fund and the AmSouth Mid Cap Fund. INVESTMENT CONCERNS A concentrated portfolio may add a measure of volatility to performance, as major fluctuations in any one holding will likely affect the fund more than a fund with a greater diversification. Equity securities (stocks) are more volatile and carry more risk than other forms of investments, including investments in high-grade fixed income securities. The net asset value per share of this Fund will fluctuate as the value of the securities in the portfolio changes. - -------------------------------------------------------------------------------- PORTFOLIO MANAGERS' PERSPECTIVE "Our goal in managing the AmSouth Select Equity Fund is to outperform the S&P 500 Stock Index(1) over a complete market cycle while experiencing less volatility than the broad stock market. We look for 20 to 25 leading companies that have a dominant market position, or well-known brand name, yet whose stock price is undervalued. To make this 'growth at a reasonable price' strategy work, we use economic theory to determine whether a company is likely to recover its dominant position after a dip. We believe our patient, long-term approach offers excellent defensive protection, which can reduce losses when the market is weak." - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- Q & A Q. How did the Fund perform during the six-month period ended January 31, 2005? A. The Fund delivered a total return of 8.94% (Class A Shares at NAV. Had the effects of the front-end sales charge been included, the return would have been lower), compared to a 8.15% total return for its benchmark, the S&P 500 Stock Index.(1) The Fund's total return does not reflect the deduction of a sales charge on Class A Shares. If reflected, the sales charge would reduce the performance quoted. With the maximum sales charge of 5.50% and recurring fees, the Fund's six month, 1 Year, 5 Year and Since Inception (9/1/98) average annual total returns for the period ended January 31, 2005, were 2.92%, 1.41%, 8.79% and 6.94%, respectively, for Class A Shares.

For performance data current to the most recent month end please visit www.amsouthfunds.com. Q. What factors affected the Fund's performance? A. Large-cap stocks generated gains during most of the period, which included a strong rally during November and December. That environment helped the Fund and its benchmark produce positive returns. This Fund's sub-advisor, OakBrook Investments, invests in select shares of industry-leading companies with steady and predictable earnings growth. We believe the Fund's managers positioned the portfolio to benefit from an economic recovery, while avoiding exposure to stocks that were likely to be hurt by rising interest rates. 4 That strategy helped the Fund stay even with the market during the first five months of the period, as short-term interest rates increased and a cyclical pick-up did occur. A decline in long-term interest rates offset some of the benefits of the managers' strategy, however. What's more, rising commodity prices had a negative impact on the Fund's holdings. Shares of the industry-leading firms in which this Fund invests tend to be consumers of commodities, rather than producers of them, and therefore suffer from rising commodity prices.+ The market experienced a sell-off in January. This Fund's holdings fared better than the benchmark in that environment, and generated most of the Fund's relative gains for the six-month period. This may reflect the fact that investors during January prized the earnings stability and predictability that this Fund emphasizes. + + The Fund's portfolio is current to January 31, 2005 and subject to change.

That approach enhanced the Fund's relative returns during the period. Stock selection boosted returns against the benchmark, particularly in the consumer discretionary and financial sectors. Sector allocation also boosted relative returns slightly. The Fund benefited from an over-weight position in energy stocks and underweight stakes in telecommunications and consumer discretionary shares. + 6 The Fund held a modest cash position throughout the period, to manage shareholder redemptions and capture developing investment opportunities.

The equity market posted solid gains during the six-month period through January, boosting the returns of the Fund and giving an even stronger lift to the broad-market S&P 500. The Fund has long emphasized large and high-quality growth stocks. That philosophy muted its performance relative to its benchmark. The disparity between the Fund's market-capitalization size, and that of its target, weighed heavily on comparative returns during this period, as smaller and sometimes riskier stocks significantly outperformed larger-company shares.+ Moreover, our Fund's traditional, long-term and rigorously focused growth style approach typically leads it to hold larger stakes than its benchmark in both the health care and the technology sectors. The recent powerful performance of energy stocks undermined the 8 Fund's relative returns. Our stock selection in the industrials and, to some extent, the health care sectors also hurt our Fund's relative performance.+ Our consumer discretionary and consumer staples allocations provided a modest lift against all of the comparative indices. Conversely, our significantly underweight position in the dramatically outperforming utilities sector hurt relative performance. Our long-established practice of eschewing the sector caused the Fund to lose some ground.+ We believe our Fund is well-positioned to compete successfully when large-cap growth stocks resume market leadership. Until then, we will continue to execute in the focused, traditional-growth style that historically has provided our Fund's above-average long term returns. + + The Fund's portfolio is current to January 31, 2005 and subject to change.

That compared to a 16.68% total return for the Fund's benchmark, the Morgan Stanley Capital International EAFE(R) (Europe, Australasia and Far East) Index.(1) The Fund's total return does not reflect the deduction of a sales charge on Class A Shares. If reflected, the sales charge would reduce the performance quoted. With the maximum sales charge of 5.50% and recurring fees, the Fund's six month, 1 Year, 5 Year and Since Inception (8/18/97) average annual total returns for the periods ended January 31, 2005, were 13.81%, 14.95%, 2.05% and 4.43%, respectively, for Class A Shares. The returns quoted assume the reinvestment of dividends and capital gains distributions. Past performance does not guarantee future results. The performance data quoted represents past performance and current returns may be lower or higher. Total return figures include change in share price, reinvestment of dividends and capital gains and does not reflect the deduction of taxes that a shareholder would pay on distributions and redemptions. The investment return and principal value will fluctuate so that an investor's shares, when redeemed may be worth more or less than the original cost. For performance data current to the most recent month end please visit www.amsouthfunds.com. Q. What factors affected the Fund's performance? A. Developed international stock markets generated strong returns during the period, helping the Fund and the benchmark produce solid gains. The dollar weakened compared to most foreign currencies. The Fund does not hedge its exposure to foreign currencies, so dollar weakness increased the Fund's returns. Strong performance among value and small-cap stocks also boosted the Fund's absolute performance. + 16 The Fund's sub-advisor, Dimensional Fund Advisors, employs a strict value methodology to construct a portfolio that is broadly diversified across geographical regions. The managers rank the stocks in each of the 21 developed markets represented in the index primarily using book value-to-market capitalization, and invest in approximately the top 30% of stocks, by number, in each country. + That approach helped the Fund outperform its benchmark, since value stocks led global stock markets during the period. The Fund's value discipline also typically leads it to hold shares with smaller average market capitalizations than the average stocks that comprise the Fund's benchmark. That dynamic also boosted relative returns, as smaller shares outperformed larger stocks for the six-month period. + + The Fund's portfolio is current to January 31, 2005 and subject to change.

Sullivan, CFA Director, Value Equity Strategies John P. Boston, CFA Chief Fixed Income Officer AmSouth Bank AmSouth Asset Investment Management, Inc. Brian Sullivan has been the portfolio manager for the AmSouth Value and AmSouth Balanced Fund since June 2004. Mr. Sullivan has more than 18 years of investment management experience and holds an MBA in finance and a bachelor's degree in economics. John Boston manages the AmSouth High Quality Bond Fund and co-manages the AmSouth Government Income Fund, AmSouth Limited Term Bond Fund and the AmSouth Balanced Fund. Mr. Boston joined the Asset Management Division in 1987. Mr. Boston earned his B.S. in Finance and Political Science from the University of North Alabama. He is a member and past president of the Alabama Society of Financial Analysts and holds the Chartered Financial Analyst designation. - -------------------------------------------------------------------------------- PORTFOLIO MANAGERS' PERSPECTIVE "The AmSouth Balanced Fund is a diversified fund that offers investors a simple and easy way to balance their investments between stocks and bonds. Within the equity component, our diversified equity strategy invests in a broad array of high quality stocks to provide long term growth. The fixed income component contains a mix of investment grade bonds to generate income. We assess market opportunities between the two asset classes and allocate assets in the Fund to potentially achieve high risk-adjusted returns. - -------------------------------------------------------------------------------- INVESTMENT CONCERNS Equity securities (stocks) are more volatile and carry more risk than other forms of investments, including investments in high-grade fixed income securities. The net asset value per share of this Fund will fluctuate as the value of the securities in the portfolio changes. Bonds offer a relatively stable level of income, although bond prices will fluctuate providing the potential for principal gain or loss. Intermediate-term, higher-quality bonds generally offer less risk than longer-term bonds and a lower rate of return. - -------------------------------------------------------------------------------- Q & A Q. How did the Fund perform during the six-month period ended January 31, 2005? A. The Fund delivered a total return of 6.26% (Class A Shares at NAV. Had the effects of the front-end sales charge been included, the return would have been lower). The Fund's benchmarks, the S&P 500 Stock Index(1) and the Lehman Brothers Government/Credit Bond Index(1), returned 8.15% and 4.02%, respectively. The Fund's total return does not reflect the deduction of a sales charge on Class A Shares. If reflected, the sales charge would reduce the performance quoted. The Fund held an average of approximately 60% of its assets in stocks and roughly 40% of its assets in bonds. Stocks significantly outperformed bonds during the period, so the Fund's emphasis on stocks helped boost returns. With the maximum sales charge of 5.50% and recurring fees, the Fund's six month, 1 Year, 5 Year and 10 Year average annual total returns for the periods ended January 31, 2005, were 0.44%, -1.15%, 5.15% and 8.72%, respectively, for Class A Shares. The returns quoted assume the reinvestment of dividends and capital gains distributions. Past performance does not guarantee future results. The performance data quoted represents past performance and current returns may be lower or higher. Total return figures include change in share price, reinvestment of dividends and capital gains and does not reflect the deduction of taxes that a shareholder would pay on distributions and redemptions. The investment return and principal value will fluctuate so that an investor's shares, when redeemed may be worth more or less than the original cost. For performance data current to the most recent month end please visit www.amsouthfunds.com. Q. What factors affected the Fund's performance? A. Stocks posted solid returns during the period, particularly during the fourth calendar quarter of 2004. That trend boosted the returns of the Fund's equity allocation. Yields on long-term bonds declined, while yields on short-term bonds rose. The Fund's fixed-income portion generated modest gains in that environment.+ 18 We maintained a higher-than-neutral stock allocation throughout the period. The Fund held 60% of its assets in stocks, compared to its neutral position of 50%. The emphasis on equities boosted the Fund's returns relative to its neutral weightings, as stocks significantly outperformed bonds. + Stock selection helped the Fund's equity allocation outperform the S&P 500. Selection in the health care sector was especially beneficial: The Fund's health care stake out-gained the health care stocks in the S&P 500 by approximately eight percentage points, largely because we avoided or under-weighted several stocks that suffered very poor returns. The Fund's superior performance in the health care sector made a significant impact on relative performance, because health care stocks comprise a sizable portion of the index and this Fund. Stock selection in the technology sector weighed on the equity allocation's returns against the stock benchmark, largely due to weak returns among certain hardware and networking stocks in the Fund's portfolio. + The Fund's bond allocation lagged its benchmark for the period. We maintained a short average duration relative to the fixed-income index, to protect against rising interest rates. That strategy left the Fund underexposed to long-term bonds, which saw their yields decline and their prices rise. We increased the Fund's average duration late in the period. + The bond allocation's returns relative to the fixed-income benchmark benefited from an emphasis on corporate bonds, which outperformed government credit. The Fund's high-quality focus prevented it from benefiting from even stronger performance among lower-quality issues, however. + + The Fund's portfolio is current to January 31, 2005 and subject to change.

The team has more than 40 years of combined investment management experience. INVESTMENT CONCERNS The Funds invest in underlying funds, so the investment performance is directly related to the performance of those underlying funds. Before investing in the Fund, investors should assess the risks associated with and types of investments made by each of the underlying funds in which the Funds invests. - -------------------------------------------------------------------------------- PORTFOLIO MANAGERS' PERSPECTIVE The Portfolios seek to provide investors with the potential to achieve a variety of long- and short-term goals, commersurate with investors' specific time horizons and tolerance for risk. Each of the four Strategic Portfolios invests in a combination of underlying mutual funds from the AmSouth fund family. Based on each Portfolio's asset-allocation target, the mangers periodically rebalance stock, bond and money market holdings--based on analysis of economic and market trends. - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- Q & A Q. How did the Funds perform during the period? A. During the six-month period ended January 31, 2005, the Funds' total returns, benchmark returns and other comparative returns were as follows: AmSouth Aggressive Growth Portfolio (Class A Shares at NAV. Had the effects of the front-end sales charge been included, the return would have been lower): 9.87% S&P 500 Stock Index(1): 8.15% Lipper Multi-Cap Core Funds Average(1): 9.47% AmSouth Growth Portfolio (Class A Shares at NAV.

For performance data current to the most recent month end please visit www.amsouthfunds.com. Q. What factors affected the Portfolios' performance? A. The stock market staged a strong rally during the fourth quarter of 2004, helping the Strategic Portfolios generate gains for the six-month period. The Portfolios' returns benefited from their broad diversification in the stock market, including funds that invest in various styles and market-cap sizes as well as international shares. Above-neutral allocations to stocks throughout the period boosted the Portfolios' returns. The Aggressive Growth Portfolio held 99% of its assets in stock during the period, compared to its neutral allocation of 85%. The Growth, Growth and Income and Moderate Growth and Income Portfolios all held equity allocations ten percentage points higher than their neutral positions.+ The diversification of the Portfolios' equity holdings helped those equity stakes outperform the broad market, as measured by the Standard & Poor's 500 Index. In particular, the Portfolios benefited from their allocations to small and medium-sized stocks, value shares and inter-national equities, all of which generated strong gains during the six-month period. The bond funds in which the Portfolios invested lagged their bench-marks, weighing down relative returns. + The Fund's portfolio is current to January 31, 2005 and subject to change.

He earned his B.S. in Interdisciplinary Studies from Berry College and holds the Chartered Financial Analyst designation. - -------------------------------------------------------------------------------- PORTFOLIO MANAGERS' PERSPECTIVE "The AmSouth Government Income Fund is more suitable for investors who seek income but also demand the safety of U.S. government securities. Although we attempt to consistently generate a high level of income, investors should be aware that yields and principal values vary and that the Fund is not guaranteed by the U.S. Government." - -------------------------------------------------------------------------------- INVESTMENT CONCERNS U.S. Government guarantees apply only to certain underlying securities of the Fund's portfolio and not the Fund's shares. Bonds offer a relatively stable level of income, although bond prices will fluctuate providing the potential for principal gain or loss. Intermediate-term, higher-quality bonds generally offer less risk than longer-term bonds and a lower rate of return. - -------------------------------------------------------------------------------- Q & A Q. How did the Fund perform during the six-month period ended January 31, 2005? A. The Fund delivered a total return of 2.00% (Class A Shares at NAV. Had the effects of the front-end sales charge been included, the return would have been lower). That compared to a 3.53% total return for the Fund's benchmark, the Lehman Brothers Mortgage Index.(1) The Fund's total return does not reflect the deduction of a sales charge on Class A Shares. If reflected, the sales charge would reduce the performance quoted. With the maximum sales charge of 4.00% and recurring fees, the Fund's six month, 1 Year, 5 Year and 10 Year average annual total returns for the periods ended January 31, 2005, were -2.07%, -1.99%, 5.21% and 5.91%, respectively, for Class A Shares.

For performance data current to the most recent month end please visit www.amsouthfunds.com. Q. What factors affected the Fund's performance during the period? This Fund invests primarily in mortgage-backed securities. Such issues fared well during the period, as investors prized their relatively high yields and the protection they offered against rising interest rates. That environment helped the Fund and its benchmark post positive returns. The Fund began the period with 50% of its assets in mortgage-backed securities, 40% in agency issues and 10% in Treasuries. We maintained those allocations through December. In January we significantly increased the Fund's weighting in mortgage-backed securities, to 82% of the Fund's assets, in order to take advantage of the attractive yields and outlook those bonds offered. This Fund's benchmark is comprised entirely of mortgage-backed securities, so the Fund's smaller weighting dragged on relative returns as those bonds performed well. That dynamic was the primary reason that the Fund lagged its benchmark. + 22 The Fund held an average duration that was modestly shorter than the benchmark throughout the period, to help protect against rising interest rates. That strategy had a slightly negative impact on returns against the benchmark, as bonds with longer durations generally performed best. + + The Fund's portfolio is current to January 31, 2005 and subject to change.

Mr. Flurry earned his B.S. in Finance from the University of Alabama and holds the Chartered Financial Analyst designation. - -------------------------------------------------------------------------------- PORTFOLIO MANAGERS' PERSPECTIVE "The AmSouth Limited Term Bond Fund was designed to fill the gap between money market funds and long-term bond funds. For investors looking for a diversified bond fund, this Fund represents the first step out on the 'risk/return' spectrum from the money market arena." - -------------------------------------------------------------------------------- INVESTMENT CONCERNS Short- or intermediate-term investment grade bonds offer less risk and generally a lower rate of return than longer-term higher yielding bonds. Bonds offer a relatively stable level of income, although bond prices will fluctuate providing the potential for principal gain or loss. Intermediate-term, higher-quality bonds generally offer less risk than longer-term bonds and a lower rate of return. - -------------------------------------------------------------------------------- Q & A Q. How did the Fund perform during the six-month period ended January 31, 2005? A. The Fund delivered a total return of 0.55% (Class A Shares at NAV. Had the effects of the front-end sales charge been included, the return would have been lower). That compared to a 1.22% total return for the Fund's benchmark, the Merrill Lynch 1-5-Year Government/Corporate Bond Index.(1) The Fund's total return does not reflect the deduction of a sales charge on Class A Shares. If reflected, the sales charge would reduce the performance quoted. With the maximum sales charge of 2.00% and recurring fees, the Fund's six month, 1 Year, 5 Year and 10 Year average annual total returns for the periods ended January 31, 2005, were -3.51%, -3.57%, 4.19% and 5.06%, respectively, for Class A Shares.

For performance data current to the most recent month end please visit www.amsouthfunds.com Q. What factors affected the Fund's performance? The Fund held a shorter average duration than the benchmark throughout the period, in order to protect against the risk of rising interest rates. That strategy hurt relative performance during the first three months, as short-term yields declined. The Fund's relatively short average duration then helped returns against the bench- mark when yields rose during the second half of the recent period. The Fund sacrificed some yield to pursue its low-duration strategy, particularly early in the period when the yield curve was steeper, with higher yields on longer-term issues+ 24 The Fund was overweight corporate bonds during the entire period, which helped relative returns significantly. One- to five-year corporate bonds returned 43 basis points (0.43%) more than the index for the period as a whole. The beneficial effect of the Fund's overweight position in corporate bonds was tempered somewhat by the overall superior credit quality of the Fund, as lower rated corporate bonds were by far the best performers. + We further increased the Fund's overweight position in corporate bonds during the period. The Fund held 53% of its assets in corporate issues as of August 1, 2004, compared to 60% by the end of the period. + + The Fund's portfolio is current to January 31, 2005 and subject to change.

The market for Florida municipal debt was similar to the national municipal market: Yields on long-term municipal bonds fell, while yields on short-term issues rose. This Fund over-weighted securities with durations of between four and five years. Yields on those issues declined only slightly, so capital appreciation was not a major factor in producing Fund returns. + We maintained a shorter average duration than that of the Fund's benchmark throughout the period, to protect against the potential for rising interest rates. That strategy prevented the Fund from holding many of the longer-term issues that performed the best during the period, hurting the Fund's returns relative to the index. We lengthened the Fund's average duration late in the period in order to capture additional yield. The Fund's holdings had an average duration of 3.86 years as of August 1, 2004, and an average duration of 4.63 years as of January 31, 2005. + The Fund invests in bonds with high credit quality. Lower-quality bonds led the market, so this Fund's high-quality mandate weighed slightly on relative returns. + + The Fund's portfolio is current to January 31, 2005 and subject to change.

Thomas, CFA Fund Manager AmSouth Bank AmSouth Asset Management, Inc. Dorothy Thomas manages the AmSouth Municipal Bond Fund, AmSouth Florida Tax-Exempt Fund and the AmSouth Tennessee Tax-Exempt Fund. Ms. Thomas joined the Asset Management Division in 1983 after working in Corporate Finance since 1973. Prior to moving to the Fixed Income team, she held positions as an equity analyst and a portfolio manager. She earned a B.A. in Economics from Stanford University and her MBA from the University of Alabama. She is a member of the Alabama Society of Financial Analysts and holds the Chartered Financial Analyst designation. - -------------------------------------------------------------------------------- PORTFOLIO MANAGER'S PERSPECTIVE "The AmSouth Tennessee Tax-Exempt Fund generates income that is exempt from both federal and the state of Tennessee income tax. The Fund only invests in securities in the top three rating classes, or of comparable quality. As with the other AmSouth bond funds, we strive to enhance long-term performance by capitalizing on expected changes in interest rates." - -------------------------------------------------------------------------------- INVESTMENT CONCERNS The geographical concentration of portfolio holdings in this Fund may involve increased risk. The Fund's income may be subject to certain state and local taxes and, depending on your tax status, the federal alternative minimum tax. Bond funds will tend to experience smaller fluctuations in value than stock funds. However, investors in any bond fund should anticipate fluctuations in price, especially for longer-term issues and in environments of rising interest rates. - -------------------------------------------------------------------------------- Q & A Q. How did the Fund perform during the six-month period ended January 31, 2005? A. The Fund delivered a total return of 1.59% (Class A Shares at NAV. Had the effects of the front-end sales charge been included, the return would have been lower). The Fund's benchmark, the Merrill Lynch 1-12-Year Municipal Bond Index(1), returned 3.46%. The Fund's total return does not reflect the deduction of a sales charge on Class A Shares. If reflected, the sales charge would reduce the performance quoted. With the maximum sales charge of 4.00% and recurring fees, the Fund's six month, 1 Year, 5 Year and 10 Year average annual total returns for the periods ended January 31, 2005, were -2.50%, -3.10%, 4.09% and 3.96%, respectively, for Class A Shares. The returns quoted assume the reinvestment of dividends and capital gains distributions. Past performance does not guarantee future results. The performance data quoted represents past performance and current returns may be lower or higher. Total return figures include change in share price, reinvestment of dividends and capital gains and does not reflect the deduction of taxes that a shareholder would pay on distributions and redemptions. The investment return and principal value will fluctuate so that an investor's shares, when redeemed may be worth more or less than the original cost. For performance data current to the most recent month end please visit www.amsouthfunds.com. Q. What factors affected the Fund's performance during the period? A. Tennessee municipal bonds generally performed in line with other states' municipal bonds during this period, as yields fell on the long end of the yield curve and rose on the short end. The Fund over-weighted securities with durations between four and five years. Yields in that section of the curve declined only modestly, so the yields produced by the Fund's portfolio were a major factor in generating returns.+ 32 We maintained a relatively short average duration throughout the period, to protect shareholders' capital in case interest rates increased. The Fund held few of the long-term issues that led the market, so the strategy dragged on relative returns for the period as a whole. We lengthened the Fund's average duration late in the period in order to capture additional yield. The Fund's portfolio held securities with an average duration of 3.75 years as of August 1, 2004, and an average duration of 4.39 years as of January 31, 2005. + This Fund's mandate calls for it to maintain a portfolio with high credit quality. High-quality bonds lagged lower-quality issues during this period, so the Fund's emphasis on high-quality securities dragged modestly on relative returns. + + The Fund's portfolio is current to January 31, 2005 and subject to change.

INVESTMENT CONCERNS Investments in the Prime, the Treasury Reserve, the Tax-Exempt, and the Institutional Prime Obligations Money Market Funds are neither insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Although the Funds seek to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in the Funds. The AmSouth Tax Exempt Money Market Fund's income may be subject to certain state and local taxes and, depending on one's tax status, the federal alternative minimum tax. - -------------------------------------------------------------------------------- Q & A Q. What factors affected the Funds' performance during the six-month period ended January 31, 2005? A. The Federal Reserve Board raised its target short-term interest rate four times, for a total increase of one percentage point. Those increases pushed up yields on short-term debt. Rising short-term yields allowed the Funds to capture additional yield for shareholders as the period progressed. The Funds' investments had average maturities shorter than those of their benchmarks throughout the period. That strategy provided the flexibility to invest in higher-yielding securities as rates rose, while protecting shareholders' capital. The Funds' relatively short average maturities boosted performance against their benchmarks. + These Funds, except for the Tax-Exempt Money Market Fund, focus on high-quality fixed- and variable-rate securities. A limited supply of high-quality commercial paper prevented the Funds from adding multiple new commercial paper names to the portfolios. The Funds found opportunities in overnight repurchase agreements, which adjust their yields on a day-to-day basis and therefore reflected changes in Federal Reserve policy. The Tax-Exempt Money Market Fund emphasized variable-rate securities, which benefited from the rising-rate environment. + o As of January 31, 2005, the Prime Obligations Fund's average maturity was 28 days, compared with 28 days on July 31, 2004 and 59 days on January 31, 2004. + o As of January 31, 2005, the Tax-Exempt Fund's average maturity was 20 days, compared with 19 days on July 31, 2004 and 35 days on January 31, 2004. + 34 o As of January 31, 2005, the Treasury Reserve Fund's average maturity was 19 days, compared with 22 days on July 31, 2004 and 45 days on January 31, 2004. + o As of January 31, 2005, the Institutional Prime Obligations Fund's average maturity was 27 days, compared with 29 days on July 31, 2004 and 64 days on January 31, 2004. + + The Fund's portfolio is current to January 31, 2005 and subject to change. 35 PIONEER AMERICA INCOME TRUST STATEMENT OF ADDITIONAL INFORMATION [ ], 2005 This Statement of Additional Information is not a Prospectus.

See accompanying notes to pro forma financial statements. Pioneer America Income Trust PRO FORMA NOTES TO COMBINING FINANCIAL STATEMENTS 12/31/04 (Unaudited) 1. Description of the Trust Pioneer America Income Trust (the Trust), is a Massachusetts statutory trust registered under the Investment Company Act of 1940 as a diversified, open-end management investment company. The investment objective of the Trust is to provide a high level of current income consistent with preservation of capital and prudent investment risk. The Trustees have authorized the issuance of five classes of shares of the Trust. After the merger, the Trust will offer six classes of shares - Class A, Class B, Class C, Investor Class, Class R and Class Y shares. Class Y shares are being offered as part of the acquisition. Class R shares were first publicly offered on April 1, 2003. Investor Class shares were first publicly offered on December 10, 2004. The Trust is not offering additional Investor Class shares except in connection with the reinvestment of dividends on the Trust's outstanding Investor Class shares. Each class of shares represents an interest in the same portfolio of investments of the Trust 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, Class C, and Class R shareowners, respectively. There is no distribution plan for Class Y shares 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 AmSouth Government Income Fund by the Trust, as if such acquisition had taken place as of January 1, 2004. Under the terms of an Agreement and Plan of Reorganization (the "Reorganization") between these two Trusts, the combination of the Trust and AmSouth Government 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 AmSouth Government Income Fund in exchange for shares of the Trust at their net asset values. The accompanying schedules of investments, statements of assets and liabilities and the related statements of operations of the Trust and AmSouth Government Income Fund have been combined as of and for the most recent fiscal year ended December 31, 2004. Following the acquisition, the Trust will be the accounting survivor. All related acquisition costs will be borne by the Advisors. These pro forma financial statements and related notes should be read in conjunction with the financial statements of the Trust and AmSouth Government Income Fund included in their annual reports to shareowners dated December 31, 2004 and July 31, 2004, respectively. Adjustments have been made to expenses for Pioneer affiliate contractual rates and duplicate services that would not have been incurred if the merger took place on January 1, 2004. 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 market quotations are not readily available are valued at their fair values as determined by, or under the direction of the Board of Trustees. Principal amounts of mortgage-backed securities are adjusted for monthly paydowns. Premiums and discounts related to certain mortgage-backed securities are amortized or accreted in proportion to the underlying monthly paydowns. Securities for which there are no other readily available valuation methods are valued at their fair values as determined by, or under the direction of the Board of Trustees. As of December 31, 2004, there were no securities fair valued. All discounts/premiums on debt securities are accreted/amortized for financial reporting purposes. Interest income is recorded on the accrual basis. Temporary cash investments are valued at amortized cost. 4. Capital Shares The pro forma net asset value per share assumes the issuance of shares of the Trust that would have been issued at December 31, 2004, in connection with the proposed acquisition. The number of shares assumed to be issued is equal to the net asset value of shares of AmSouth Government Income Fund, as of December 31, 2004, divided by the net asset value per share of the Trust's shares as of December 31, 2004. The pro forma number of shares outstanding, by class, for the combined Trust consists of the following at December 31, 2004: - -------------------------------------------------------------------------------------- Shares of Additional Shares Total Outstanding The Trust Assumed Issued Shares Class of Shares Pre-Combination In Reorganization Post-Combination - -------------------------------------------------------------------------------------- Class A 12,614 1,704 14,318 - -------------------------------------------------------------------------------------- Class B 4,071 692 4,763 - -------------------------------------------------------------------------------------- Class C 2,849 2,849 - -------------------------------------------------------------------------------------- Class R 84 84 - -------------------------------------------------------------------------------------- Class Y 0 18,802 18,802 - -------------------------------------------------------------------------------------- Investor Class 5,257 5,257 - -------------------------------------------------------------------------------------- 5. Federal Income Taxes Each Trust has elected to be taxed as a "regulated investment company" under the Internal Revenue Code. After the acquisition, it will continue to be the Trust'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 Trusts is substantially the same for both financial and federal income tax purposes. The cost of investments will remain unchanged for the combined Trust. PART C OTHER INFORMATION PIONEER AMERICA INCOME TRUST ITEM 15.
