NOTICE OF SPECIAL MEETING OF SHAREHOLDERS SCHEDULED FOR DECEMBER 8, 2004 To the Shareholders of the Funds: A joint special meeting of shareholders (the "Meeting") for each of the Safeco Funds will be held at the offices of Safeco Mutual Funds, King Auditorium, 4854 154th Place, N.E., Redmond, WA 98052 on December 8, 2004 at 2:00 p.m., local time, to consider the following: 1. With respect to each Safeco Fund, a proposal to approve an Agreement and Plan of Reorganization. Under the Agreement and Plan of Reorganization, your Safeco Fund will transfer all of its assets to an investment company (each a "Pioneer Fund") managed by Pioneer Investment Management, Inc. ("Pioneer") in exchange for Investor Class shares of the Pioneer Fund. The Pioneer Fund also will assume your Safeco Fund's liabilities that are included in the calculation of your Safeco Fund's net assets at the closing. Generally, each Pioneer Fund is an existing mutual fund with a substantially similar investment objective and similar investment policies as your Safeco Fund. In the case of certain Safeco Funds, the Pioneer Fund is a newly organized mutual fund with a substantially similar investment objective and similar investment policies as your Safeco Fund. Holders of all share classes of your Safeco Fund will receive Investor Class shares of the corresponding Pioneer Fund. Investor Class shares of the applicable Pioneer Fund will be distributed to shareholders in proportion to the relative net asset value of their share holdings on the closing date of the reorganization. Following the reorganization, your Safeco Fund will then be dissolved. As a result of the reorganization you will become shareholders of the Pioneer Fund. Your Board of Trustees recommends that you vote FOR this proposal. 2. With respect to each Safeco Fund, a proposal to approve an interim investment advisory agreement between your Safeco Fund and Pioneer. Pioneer has provided advisory services for your Safeco Funds pursuant to this agreement since August 2, 2004, when the advisory agreement between your Safeco Fund and Safeco Asset Management Company terminated. Approval of the interim investment advisory agreement will enable Pioneer to receive advisory fees currently held in escrow. Your Board of Trustees recommends that you vote FOR this proposal. 3. Any other business that may properly come before the Meeting. Shareholders of record as of the close of business on October 8, 2004, are entitled to vote at the Meeting and any related follow-up meetings. Whether or not you expect to attend the Meeting, please complete and return the enclosed proxy card.

On August 2, 2004, Symetra Financial Corporation ("Symetra") acquired certain assets from Safeco Corporation, including all of the capital stock of SAM. While reviewing the operations of SAM in anticipation of that transaction, Symetra determined that engaging in the business of investment adviser to the Safeco Funds was not a core business that it intended to continue. After investigating and discussing several alternatives for ongoing investment management of the Safeco Funds with the Trustees, Symetra conducted a search for a new investment adviser for the Safeco Funds. Ultimately Symetra decided to recommend to the Boards that Pioneer Investment Management, Inc. ("Pioneer") be hired to manage the Safeco Funds on an interim basis until the Reorganizations occur and the Safeco Funds be reorganized into similar mutual funds managed by Pioneer. The Boards met at a series of meetings in July 2004. 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 Safeco Funds' shareholders, and the quality of the services offered by Pioneer. At these meetings, the Trustees met with representatives of Pioneer. In addition to these general factors, the Trustees also considered these and other factors specifically in the context of each Reorganization. On July 30, 2004, the Boards of Trustees, including all of the Trustees who are not interested persons of SAM (the "Independent Trustees"), unanimously voted to approve each of the Reorganizations. In approving the Reorganization, the Board determined that the Reorganizations were in the best interests of the Safeco Funds' shareholders and the interests of existing Safeco Funds' shareholders will not be diluted as a result of the Reorganizations. Pioneer believes that it can offer favorable long-term investment performance and enhanced shareholder services to the Safeco Funds' shareholders. The Reorganizations will, by combining the assets of two mutual funds and, by being part of a family of funds with greater distribution capabilities, offer the potential for increased economies of scale. Increased economies of scale have the potential of benefiting the shareholders of your Safeco 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 Safeco 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 SAM, the investment adviser to each of the Safeco Funds until August 2, 2004, was acquired by Symetra. Symetra informed the Board that it was not interested in continuing to provide investment advisory services to the Safeco Funds. Therefore, a change in your Safeco Fund's investment adviser was necessary; o The track record of Pioneer in managing the Pioneer Funds as compared to the historical performance of the Safeco Funds; o The resources of Pioneer, including its infrastructure in shareholder services; o The opportunity to be part of a significantly larger family of funds, with additional product offerings and enhanced shareholder servicing options; o Pioneer's commitment until December 10, 2006, or such later date that is the second anniversary of the day on which each Reorganization closes (the "Closing Date") to limit the total operating expenses of the Investor Class shares of each Pioneer Fund; and o Shareholders who own shares in their name as of the closing of the Reorganization (i.e., not in the name of a broker or other intermediary) and maintain their account may purchase Class A shares of the corresponding Pioneer Fund through such account in the future or may exchange those shares for Class A shares of another Pioneer Fund or purchase Class A share of another Pioneer Fund without paying any sales charge. Investor Class shares will not be offered after the Reorganizations. How Each Reorganization will Work o Safeco Fund shareholder-directed exchanges and purchases made by check, ACH, or wire will be accepted up until 1 p.m. (Pacific Time) on Wednesday, December 8, 2004. Exchange and purchase requests received after this deadline will be rejected and returned. Purchase and exchange requests made by Safeco Fund shareholders through financial institutions or advisers must do so earlier to ensure the trade can be processed within this deadline. Financial institutions and advisers that trade electronically (NSCC) with the Safeco Funds can place exchange and purchase requests up until 1 p.m. (Pacific Time) on Tuesday, December 7, 2004. 4 Exchanges and purchases received after this deadline will be rejected and returned. The Safeco Funds will not process purchases made via automatic investment method (AIM) after December 8, 2004. Dividend/capital gain reinvestment and established systematic exchanges will continue through December 10, 2004. o Each Safeco Fund will transfer all of its assets to a corresponding Pioneer Fund. Each Pioneer Fund will assume the corresponding Safeco Fund's liabilities that are included in the calculation of such Safeco Fund's net asset value at the closing of the Reorganization (the "Closing Date"). o Each Pioneer Fund will issue Investor Class shares to the corresponding Safeco Fund in amounts equal to the aggregate net asset value of that Safeco Fund's shares. Shareholders of your Safeco Fund will receive Investor Class 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, shareholders will hold the shares of the Pioneer Fund with the same aggregate net asset value as the shares of your Safeco Fund that you held immediately prior to the Reorganization. o Each Safeco Fund will be dissolved after the Closing Date. o Shares of the Investor Class of a Pioneer Fund will automatically convert to Class A shares of the Pioneer Fund at the end of the calendar month that is two years after the Closing Date. o Pioneer acts as investment adviser to each Pioneer Fund. Until December 10, 2006, or such later date that is the second anniversary of the Closing Date, Pioneer has agreed to limit each Pioneer Fund's expenses (excluding extraordinary expenses) for Investor Class shares. Pioneer is not required to limit any expenses after the second anniversary of the Closing Date. 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 Safeco Funds or the shareholders of the Safeco Funds. o In recommending each of the Reorganizations, the Trustees of your Safeco Fund have determined that the Reorganization is in the best interest of your Safeco Fund and will not dilute the interests of shareholders of your Safeco 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 Safeco Trust 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 after 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 fund and institutional accounts. Pioneer or its predecessors have been managing mutual funds since 1928 and at June 30, 2004 had, together with its affiliates, over $35 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 Investor Class shares to be issued in the Reorganization, each Pioneer Fund also offers Class A shares (subject to an initial sales load and a Rule 12b-1 Plan), Class B shares (subject to a contingent deferred sales charge and a Rule 12b-1 Plan), and 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 Y shares (which are an institutional class of shares and are not subject to a sales charge or a Rule 12b-1 Plan) and Class R shares (which are offered only to certain retirement plans). Who Bears the Expenses Associated with the Reorganizations Pioneer and Symetra will pay all out of pocket expenses of the Safeco Funds and the Pioneer Funds associated with the Reorganizations, including, but not limited to: (1) the expenses associated with the preparation, printing and mailing of any shareholder communications, including this joint Proxy Statement/Prospectus, and any filings with the SEC and other governmental authorities in connection with the Reorganizations; (2) the fees and expenses of any proxy solicitation firm retained in connection with the Reorganizations; (3) the legal fees and expenses incurred by the Safeco Funds in connection with the Reorganizations; and (4) the Trustee's fees and out of pocket expenses incurred as a result of the Reorganizations. 5 Will Pioneer and Symetra Benefit from the Reorganizations Pioneer will benefit from managing a larger pool of assets. Pioneer is also acquiring certain assets associated with SAM's mutual funds and institutional account advisory business. In consideration for the acquisition of these assets and certain covenants from Symetra and SAM, including their assistance in facilitating the Reorganizations and their obligation to indemnify Pioneer against certain liabilities, Pioneer has agreed to pay Symetra up to $30 million. This amount is subject to downward adjustment if the net assets of the Safeco Funds that approve the Reorganizations (together with assets in certain other accounts) are less than $2.6 billion. Under this agreement, Pioneer and Symetra have also agreed, among other things, that (i) once the Investor Class converts to Class A shares, Pioneer Funds Distributor, Inc. ("PFD"), the principal underwriter of the Pioneer Funds, shall make payments to Safeco Securities, Inc. ("Safeco Securities"), the principal underwriter of the Safeco Funds, pursuant to a Rule 12b-1 plan equal to 0.25% of the average daily net assets attributable to accounts maintained by former shareholders of the Safeco Funds; (ii) PFD will make additional continuing payments out of its own resources to Safeco Securities, following Pioneer's acquisition of assets from SAM, at an annual rate of 0.05% of the average daily net assets of any Pioneer Fund held by or for the account of any former shareholders of the Safeco Funds (including assets invested in any Pioneer Fund as a result of the Reorganization or otherwise) and, in connection with purchases of shares of the Pioneer Funds by former shareholders of the Safeco Funds after the acquisition, PFD will pay out of its own resources to Safeco Securities an amount equal to 0.20% of the amount of such purchases; and (iii) Symetra and SAM will be subject to certain non-competition provisions. Why is an Interim Investment Advisory Agreements being Voted On Having determined to recommend the Reorganizations, the Trustees elected to appoint Pioneer as investment adviser to each Safeco Fund until the closing of the Reorganizations given that Symetra had indicated that it did not wish to continue to offer investment advisory services to the Safeco Funds. Under the Investment Company Act, shareholders must approve any new investment advisory agreement for a Safeco Fund. However, Rule 15a-4 under the Investment Company Act permits the Board to appoint an adviser on an interim basis without prior shareholder approval of an investment advisory agreement with the adviser if the new adviser agrees to provide such services on the same terms as the previous adviser. An adviser may act on such an interim basis for a period of 150 days. Because Pioneer will be making the payment to Symetra as discussed above, any fees that Pioneer would be entitled to under the interim investment advisory agreement will be held in escrow until shareholder approval of that agreement is obtained. If shareholders of a Safeco Fund do not approve the interim investment advisory agreement, Pioneer will not receive the fee under the current investment advisory agreement with SAM but instead would be paid a fee based upon Pioneer's cost in managing the Safeco Fund. If the Reorganizations and the interim investment advisory agreements are not approved by December 30, 2004, Pioneer will no longer provide advisory services to the Safeco Funds, unless an extension of the 150 day period is permitted by a rule or independent position of the staff of the SEC. If both the Reorganization and appointment of Pioneer are approved, the interim investment advisory agreement will continue in effect until the closing of the Reorganization. What Happens if a Reorganization is not Approved If a Reorganization is not approved by shareholders, the Board will consider what action to take. Such action could include liquidating the Safeco Fund or seeking SEC relief to permit Pioneer to serve as investment adviser beyond the 150-day limitation period. Who is Eligible to Vote Shareholders of record on October 8, 2004 are entitled to attend and vote at the Meeting or any adjournment of the Meeting. On each proposal, all shareholders of a Safeco Fund, regardless of the class of shares held, will vote together as a single 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 and the interim advisory agreement with Pioneer. If any other business comes before the Meeting, your shares will be voted at the discretion of the persons named as proxies. 6 TABLE OF CONTENTS Page --- INTRODUCTION ..................................................................... 3 PROPOSAL 1(a) -- SAFECO CALIFORNIA TAX-FREE INCOME FUND .......................... 8 PROPOSAL 1(b) -- SAFECO HIGH-YIELD BOND FUND ..................................... 23 PROPOSAL 1(c) -- SAFECO INTERMEDIATE-TERM BOND FUND .............................. 37 PROPOSAL 1(d) -- SAFECO INTERMEDIATE-TERM MUNICIPAL BOND FUND .................... 52 PROPOSAL 1(e) -- SAFECO INTERMEDIATE-TERM U.S. GOVERNMENT FUND ................... 68 PROPOSAL 1(f) -- SAFECO MONEY MARKET FUND ........................................ 84 PROPOSAL 1(g) -- SAFECO MUNICIPAL BOND FUND ...................................... 97 PROPOSAL 1(h) -- SAFECO TAX-FREE MONEY MARKET FUND ............................... 112 TERMS OF EACH AGREEMENT AND PLAN OF REORGANIZATION ............................... 125 TAX STATUS OF EACH REORGANIZATION ................................................ 125 PROPOSAL 2(a)-(h) -- APPROVAL OF PIONEER AS INVESTMENT ADVISER FOR EACH FUND ..... 127 VOTING RIGHTS AND REQUIRED VOTE .................................................. 130 ADDITIONAL INFORMATION ABOUT THE PIONEER FUNDS ................................... 130 FINANCIAL HIGHLIGHTS ............................................................. 137 INFORMATION CONCERNING THE MEETING ............................................... 142 OWNERSHIP OF SHARES OF THE FUNDS ................................................. 144 EXPERTS .......................................................................... 149 AVAILABLE INFORMATION ............................................................ 149 EXHIBIT A-1 -- FORM OF AGREEMENTS AND PLANS OF REORGANIZATION (C/D) ..............

You should read carefully the entire Proxy Statement/Prospectus, including the form of Agreement and Plan of Reorganization attached as EXHIBIT A-2 because they contain details that are not in the summary. The Investor Class shares to be issued in the Reorganization will convert to Class A shares after two years. Class A shares will have higher expenses per share than Investor Class shares due to the Rule 12b-1 Plan. In addition, although Pioneer has agreed to limit the expenses attributable to Investor Class shares, Pioneer is not required to limit the expenses attributable to Class A shares. In the table below, if a row extends across the entire table, the policy disclosed applies to both your Safeco Fund and the Pioneer Fund.

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 The investment adviser's judgment about the credit quality, attractiveness or relative value of a particular security proves to be incorrect The Investor Class shares to be issued in the Reorganization will convert to Class A shares after two years. Class A shares will have higher expenses per share than Investor Class shares due to the Rule 12b-1 Plan. In addition, although Pioneer has agreed to limit the expenses attributable to Investor Class shares, Pioneer is not required to limit the expenses attributable to Class A shares. Investing in mutual fund shares is not the same as making a bank deposit. Your investment is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. You could lose money by investing in either Fund. Past Performance Set forth below is performance information for Safeco California Tax-Free Income Fund.

In addition, shareholders of your Safeco Fund who own shares in their own name (i.e., not in the name of a broker or other intermediary) and maintain such account as of the closing of the Reorganization may purchase Class A shares of Pioneer California Tax Free Income Fund or of any fund in the Pioneer family of funds through such account in the future without paying this sales charge. (2) As described above, SAM had contractually agreed to reimburse Safeco California Tax-Free Income Fund for certain fund operating expenses (but not all of the operating expenses of the Fund) that exceeded the rate of 0.40% per annum of the Fund's average daily net assets. This arrangement included all fund operating expenses except management fees, Rule 12b-1 fees, brokerage commissions, interest, and extraordinary expenses. In 2003, SAM began voluntarily reimbursing the Fund to the extent that its total expenses exceeded the rate of 0.86% per annum of the Fund's average daily net assets for Class A shares, 1.61% per annum for Class B and Class C shares, and 0.63% per annum for Investor Class shares. The above table reflects "contractual" expense reimbursements from SAM, if any, but does not reflect "voluntary" expense reimbursements by SAM. (3) Pioneer has agreed that through the second anniversary of the closing of the Reorganization, Pioneer will limit the expenses (excluding extraordinary expenses) of the Investor Class shares of Pioneer California Tax Free Income Fund to 0.63% of average daily net assets. (4) There is a higher charge for international wire redemptions, which may vary by country or dollar amount. (5) A low balance fee is charged once each year in December for accounts with balances under $1,000 in your Safeco Fund. (6) Purchases of $1,000,000 or more of Class A shares of your Safeco Fund are not subject to a front-end sales charge, but a 1.00% deferred sales charge will apply to redemptions made in the first twelve months. (7) The contingent deferred sales charge on Class B shares of your Safeco Fund reduces to zero after six years from purchase, and the Class B shares convert to Class A shares at that time. (8) The contingent deferred sales charge on Class C shares applies only to redemptions made in the first twelve months after purchase. 19 9 The Investor Class shares to be issued in the Reorganization will convert to Class A shares after two years. Class A shares will have higher expenses per share than Investor Class shares due to the Rule 12b-1 Plan. In addition, although Pioneer has agreed to limit the expenses attributable to Investor Class shares, Pioneer is not required to limit the expenses attributable to Class A shares. 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, (e) the expense limitations are in effect for five years for Safeco California Tax-Free Income Fund and two years for Pioneer California Tax Free Income Fund and (f) and the Investor Class shares of Pioneer California Tax-Free Income Fund convert to Class A shares after two years. 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, SAM, the investment adviser to the Fund until August 2, 2004, was acquired by Symetra. Symetra informed the Trustees that it did not intend to continue to provide investment advisory services to the Safeco Funds. Consequently, a change in your Safeco Fund's investment adviser was necessary. Second, the resources of Pioneer. At June 30, 2004, Pioneer managed over 62 investment companies and accounts with approximately $35 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 June 30, 2004, assets under management of UniCredito Italiano S.p.A. were approximately $151 billion worldwide. Shareholders of your Safeco Fund would become part of a significantly larger family of funds that offers a more diverse array of investment options and enhanced shareholder account 20 options. The Pioneer family of mutual funds offers over 62 funds, including domestic and international equity and fixed income funds and a money market fund that will be available to your Safeco 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's commitment until the second anniversary of the Reorganization to limit the expenses (excluding extraordinary expenses) of the Investor Class of Pioneer California Tax Free Income Fund to 0.63% of average daily net assets. This expense ratio is lower than both the gross expenses and expenses net of expense reimbursement of the Class A shares and lower than the net expenses of Investor Class shares of your Safeco Fund. Although you will experience higher expenses once the Investor Class shares convert to Class A shares after two years, your expenses will remain the same until the second anniversary of the Reorganization. Fourth, shareholders who own shares in their name as of the closing of the Reorganization (i.e., not in the name of a broker or other intermediary) and maintain their account may purchase additional Class A shares of the corresponding Pioneer Fund through such account in the future or may exchange those shares for Class A shares of another Pioneer Fund or purchase Class A share of another Pioneer Fund without paying any sales charge. Fifth, the Investor Class shares of Pioneer California Tax Free Income Fund received in the Reorganization will provide Safeco California TF Income Fund shareholders with exposure to substantially the same investment product as they currently have. Pioneer and Symetra will pay all out of pocket expenses of the Safeco Funds and the Pioneer Funds associated with the Reorganizations, including, but not limited to: (1) the expenses associated with the preparation, printing and mailing of any shareholder communications, including this joint Proxy Statement/Prospectus, and any filings with the SEC and other governmental authorities in connection with the Reorganizations; (2) the fees and expenses of any proxy solicitation firm retained in connection with the Reorganizations; (3) the legal fees and expenses incurred by the Safeco Funds in connection with the Reorganizations; and (4) the Trustee fees and out of pocket expenses incurred as a result of the Reorganizations. The Trustees also considered that Pioneer and Symetra will benefit from the Reorganization. See "Certain Agreements between Pioneer and Symetra." The Board of Trustees of Pioneer California Tax Free Income Fund also considered that the Reorganization presents an excellent opportunity for the Pioneer California Tax Free Income 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 Pioneer California Tax Free Income Fund. 21 CAPITALIZATION The following table sets forth the capitalization of each Fund, as of September 30, 2004, and the pro forma capitalization of the combined Fund as of September 30, 2004.

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 debt securities in the Fund's portfolio to decline o The issuer of a security owned by a 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 investment adviser's judgment about the attractiveness, relative value or potential appreciation of a particular sector, security or investment strategy proves to be incorrect o A downturn in equity markets causes the price of convertible securities to drop even when the prices of below investment grade bonds otherwise would not go down Investment in high yield securities involves substantial risk of loss. High yield 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, an investment in either Fund is subject to the following specific risks: 29 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 In addition, each Fund holds a material percentage of the outstanding debt securities of certain high yield issuers, which practice may adversely impact the liquidity and market value of those investments. Investments in the Funds are not bank deposits and are not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. You could lose money by investing in either Fund. The Investor Class shares to be issued in the Reorganization will convert to Class A shares after two years. Class A shares will have higher expenses per share than Investor Class shares due to the Rule 12b-1 Plan. In addition, although Pioneer has agreed to limit the expenses attributable to Investor Class shares, Pioneer is not required to limit the expenses attributable to Class A shares. 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.

Pioneer High Yield Fund's Investor Class shares will not be outstanding prior to the closing of the Reorganization and consequently have no performance history. However, the performance record of the Investor Class would be modestly higher than the performance of Class A shares due to the lower expenses applicable to the Investor Class. The most recent portfolio manager's discussion of each Fund's performance is attached as Exhibit D. 32 The Funds' Fees and Expenses Shareholders of both Funds pay various fees and expenses, either directly or indirectly.

In addition, shareholders of your Safeco Fund who own shares in their own name (i.e., not in the name of a broker or other intermediary) and maintain such account as of the closing of the Reorganization may purchase Class A shares of Pioneer High Yield Fund or of any fund in the Pioneer family of funds through such account in the future without paying this sales charge. (2) As described above, SAM had contractually agreed to reimburse Safeco High-Yield Bond Fund for certain fund operating expenses (but not all of the operating expenses of the Fund) that exceeded the rate of 0.40% per annum of the Fund's average daily net assets. This arrangement included all fund operating expenses except management fees, Rule 12b-1 fees, brokerage commissions, interest, and extraordinary expenses. In 2003, SAM began voluntarily reimbursing the Fund to the extent that its total expenses exceeded the rate of 1.15% per annum of the Fund's average daily net assets for Class A shares, 1.90% per annum for Class B and Class C shares, and 0.90% per annum for Investor Class shares. The above table reflects "contractual" expense reimbursements from SAM, if any, but does not reflect "voluntary" expense reimbursements by SAM. (3) Pioneer has agreed that through the second anniversary of the closing of the Reorganization, Pioneer will limit the expenses (excluding extraordinary expenses) of the Investor Class shares of Pioneer High Yield Fund to 0.90% of average daily net assets. (4) There is a higher charge for international wire redemptions, which may vary by country or dollar amount. (5) A low balance fee is charged once each year in December for accounts with balances under $1,000 in your Safeco Fund. (6) Purchases of $1,000,000 or more of Class A shares of your Safeco Fund are not subject to a front-end sales charge, but a 1.00% deferred sales charge will apply to redemptions made in the first twelve months except with respect to participant-directed redemptions from qualified retirement plans. (7) The contingent deferred sales charge on Class B shares of your Safeco Fund reduces to zero after six years from purchase, and the Class B shares convert to Class A shares at that time. (8) The contingent deferred sales charge on Class C shares applies only to redemptions made in the first twelve months after purchase. 33 (9) The Investor Class shares to be issued in the Reorganization will convert to Class A shares after two years. Class A shares will have higher expenses per share than Investor Class shares due to the Rule 12b-1 Plan. In addition, although Pioneer has agreed to limit the expenses attributable to Investor Class shares, Pioneer is not required to limit the expenses attributable to Class A shares. Class A shares do not currently have an expense limitation and may be subject to higher total operating expenses. 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, (e) the expense limitations are in effect for five years for Safeco High-Yield Bond Fund and two years for Pioneer High Yield Fund and (f) and the Investor Class shares of Pioneer High Yield Fund convert to Class A shares after two years. 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, SAM, the investment adviser to the Safeco Fund until August 2, 2004, was acquired by Symetra. Symetra informed the Trustees that it did not intend to continue to provide investment advisory services to the Safeco Funds. Consequently, a change in your Safeco Fund's investment adviser was necessary. Second, the investment performance of Pioneer High Yield Fund, which has one of the best performance records of any mutual fund specializing in high yield securities. For the one and five year periods ended June 30, 2004, Class A shares of Pioneer High Yield Fund had an average annual return of 11.63% and 14.31% compared to an average annual return of the Class A shares and Investor Class shares 34 of 6.42% and 11.67% (one year) and -0.42% and 0.74% (five years), 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 June 30, 2004, Pioneer managed over 62 investment companies and accounts with approximately $35 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 June 30, 2004, assets under management of UniCredito Italiano S.p.A. were approximately $151 billion worldwide. Shareholders of your Safeco 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 62 funds, including domestic and international equity and fixed income funds and a money market fund that will be available to your Safeco 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 High Yield Fund's lower operating expenses and Pioneer's commitment until the second anniversary of the Reorganization to limit the expenses (excluding extraordinary expenses) of the Investor Class of Pioneer High Yield Fund to 0.90% of average daily net assets. The estimated expenses of the Investor Class shares of Pioneer High Yield Fund are below both the gross expenses and expenses net of contractual expense reimbursement of each class of shares of your Safeco Fund. Although you will experience higher expenses once the Investor Class shares convert to Class A shares after two years, Pioneer High Yield Fund's Class A expense ratio for the most recent fiscal year was 1.06% of average daily net assets, which was below the net expenses of the Class A shares of your Safeco Fund and only one basis point above the net expenses of the Investor Class of your Safeco Fund. Fifth, the substantially larger size of Pioneer High Yield Fund offers greater opportunity for diversification of the investment portfolio, which should help to reduce risks. Sixth, shareholders who own shares in their name as of the closing of the Reorganization (i.e., not in the name of a broker or other intermediary) and maintain their account may purchase additional Class A shares of the corresponding Pioneer Fund through such account in the future or may exchange those shares for Class A shares of another Pioneer Fund or purchase Class A share of another Pioneer Fund without paying any sales charge. Seventh, the Investor Class shares of Pioneer High Yield Fund received in the Reorganization will provide Safeco High-Yield Bond Fund shareholders with exposure to substantially the same investment product as they currently have. Pioneer and Symetra will pay all of out of pocket expenses of the Safeco Funds and the Pioneer Funds associated with the Reorganizations, including, but not limited to: (1) the expenses associated with the preparation, printing and mailing of any shareholder communications, including this joint Proxy Statement/Prospectus, and any filings with the SEC and other governmental authorities in connection with the Reorganizations; (2) the fees and expenses of any proxy solicitation firm retained in connection with the Reorganizations; (3) the legal fees and expenses incurred by the Safeco Funds in connection with the Reorganizations; and (4) the Trustee fees and out of pocket expenses incurred as a result of the Reorganizations. The Trustees considered that Pioneer and Symetra will benefit from the Reorganization. See "Certain Agreements between Pioneer and Symetra." The Board of Trustees of Pioneer High Yield Fund also considered that the Reorganization presents an excellent opportunity for the Pioneer High Yield 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 Pioneer High Yield Fund and its shareholders. 35 CAPITALIZATION The following table sets forth the capitalization of each Fund as of September 30, 2004, and the pro forma capitalization of the combined Fund as of September 30, 2004.

The table should not be relied upon to determine the amount of Pioneer High Yield 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 Safeco Fund. Similarly, the Board of Trustees of Pioneer High Yield Fund, including its Independent Trustees, approved the Reorganization. They also determined that the Reorganization is in the best interests of Pioneer High Yield Fund. The Trustees recommend that the shareholders of your Safeco Fund vote FOR the proposal to approve the Agreement and Plan of Reorganization. 36 Safeco Intermediate-Term Bond Fund and Pioneer Bond 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 they contain details that are not in the summary. The Investor Class shares to be issued in the Reorganization will convert to Class A shares after two years. Class A shares will have a higher expenses per share than Investor Class shares due to the Rule 12b-1 Plan. In addition, although Pioneer has agreed to limit the expenses attributable to Investor Class shares, Pioneer is not required to limit the expenses attributable to Class A shares.

The market value of fixed income securities tends to be more volatile the longer the maturity of such security. Since Pioneer Bond Fund may invest in securities of longer maturity than your Safeco Fund, an investment in Pioneer Bond Fund may have correspondingly greater risk. 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 debt securities in the Fund's portfolio to decline. o The issuer of a security owned by a 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 investment adviser's judgment about the attractiveness, relative value or potential appreciation of a particular sector, security or investment strategy proves to be incorrect. o A downturn in equity markets causes the price of convertible securities to drop even when the prices of below investment grade bonds otherwise would not go down. 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. 44 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 (FHLB), 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 the Funds 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. The Investor Class shares to be issued in the Reorganization will convert to Class A shares after two years. Class A shares will have higher expenses per share than Investor Class shares due to the Rule 12b-1 Plan. In addition, although Pioneer has agreed to limit the expenses attributable to Investor Class shares, Pioneer is not required to limit the expenses attributable to Class A shares. 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.

Pioneer Bond Fund's Investor Class shares will not be outstanding prior to the closing of the Reorganization and consequently have no performance history. However, the performance record of the Investor Class would be modestly higher than the performance of Class A, B and C shares due to the lower expenses applicable to the Investor Class. The most recent portfolio manager's discussion of each Fund's performance is attached as Exhibit D. 47 The Funds' Fees and Expenses Shareholders of both Funds pay various fees and expenses, either directly or indirectly. The tables below show the fees and expenses that you would pay if you were to buy and hold shares of each Fund. The expenses in the tables appearing below are based on (i) for your Safeco Fund, the expenses of your Safeco Fund for the period ended December 31, 2003 and (ii) for Pioneer Bond Fund, the expenses of Pioneer Bond Fund for the period ended June 30, 2004. Future expenses for all share classes may be greater or less.

In addition, shareholders of your Safeco Fund who own shares in their own name (i.e., not in the name of a broker or other intermediary) and maintain such account as of the closing of the 59Reorganization may purchase Class A shares of Pioneer Bond Fund or of any fund in the Pioneer family of funds through such account in the future without paying this sales charge. (2) As described above, SAM had contractually agreed to reimburse Safeco Intermediate-Term Bond Fund for certain Fund operating expenses (but not all of the operating expenses of the Fund) that exceeded the rate of 0.40% per annum of the Fund's average daily net assets. This arrangement included all fund operating expenses except management fees, Rule 12b-1 fees, brokerage commissions, interest, and extraordinary expenses. In 2003, SAM began voluntarily reimbursing the Fund to the extent that its total expenses exceeded the rate of 0.99% per annum of the Fund's average daily net assets for Class A shares, 1.74% per annum for Class B and Class C shares, and 0.74% per annum for Investor Class shares. The above table reflects "contractual" expense reimbursements from SAM, if any, but does not reflect "voluntary" expense reimbursements by SAM. (3) Pioneer has agreed that through the second anniversary of the closing of the Reorganization, Pioneer will limit the expenses (excluding extraordinary expenses) of the Investor Class shares of Pioneer Bond Fund to 0.74% of average daily net assets. (4) There is a higher charge for international wire redemptions, which may vary by country or dollar amount. (5) A low balance fee is charged once in year in December for accounts with balances under $1,000 in your Safeco Fund. (6) Purchases of $1,000,000 or more of Class A shares of your Safeco Fund are not subject to a front-end sales charge, but a 1.00% deferred sales charge will apply to redemptions made in the first twelve months except with respect to participant-directed redemptions from qualified retirement plans. (7) The contingent deferred sales charge on Class B shares of your Safeco Fund reduces to zero after five years from purchase, and the Class B shares convert to Class A shares at that time. (8) The contingent deferred sales charge on Class C shares applies only to redemptions made in the first twelve months after purchase. 48 (9) The Investor Class shares to be issued in the Reorganization will convert to Class A shares after two years. Class A shares will have higher expenses per share than Investor Class shares due to the Rule 12b-1 Plan. In addition, although Pioneer has agreed to limit the expenses attributable to Investor Class shares, Pioneer is not required to limit the expenses attributable to Class A shares. 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, (e) the expense limitations are in effect five years Safeco Intermediate-Term Bond Fund and two years for Pioneer Bond Fund and (f) and the Investor Class shares of Pioneer Bond Fund convert to Class A shares after two years. 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, SAM, the investment adviser to the Safeco Fund until August 2, 2004, was acquired by Symetra. Symetra informed the Trustees that it did not intend to continue to provide investment advisory services to the Safeco Funds. Consequently, a change in your Safeco Fund's investment adviser was necessary. Second, the investment performance of Pioneer Bond Fund, which has outperformed your Safeco Fund over the most recent one, five and ten year periods. For the one, five and ten year periods ended June 30, 2004, Class A shares of Pioneer Bond Fund had an average annual return of 2.98%, 6.70% and 6.72%, respectively, compared to an average annual return of the Class A shares and Investor Class shares of 3.66% and 0.02% (one year), 4.86% and 5.86% (five years) and 5.24% and 5.88% (ten years), respectively, during the same period. In addition, the Trustees considered the track record of Pioneer in managing equity and fixed income mutual funds. 49 Third, the resources of Pioneer. At June 30, 2004, Pioneer managed over 62 investment companies and accounts with approximately $35 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 June 30, 2004, assets under management of UniCredito Italiano S.p.A. were approximately $151 billion worldwide. Shareholders of your Safeco 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 62 funds, including domestic and international equity and fixed income funds and a money market fund that will be available to your Safeco 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 Bond Fund's lower gross expenses and Pioneer's commitment until the second anniversary of the Reorganization to limit the expenses (excluding extraordinary expenses) of the Investor Class of Pioneer Bond Fund to 0.74 % of average daily net assets. The gross expense ratio of Pioneer Bond Fund's Class A shares is lower than the gross expense ratio of each class of shares of your Safeco Fund. In addition, the net expense ratio of the Investor Class of Pioneer Bond Fund is lower than the net expenses of the Class A, Class B and Class C shares of your Safeco Fund and the same as the net expenses of the Investor Class. Although you will experience higher expenses once the Investor Class shares convert to Class A shares after two years, your expenses will remain the same until the second anniversary of the Reorganization. Fifth, the substantially larger size of Pioneer Bond Fund offers greater opportunity for diversification of the investment portfolio, which should help to reduce risks. Sixth, shareholders who own shares in their name as of the closing of the Reorganization (i.e., not in the name of a broker or other intermediary) and maintain their account may purchase additional Class A shares of the corresponding Pioneer Fund through such account in the future or may exchange those shares for Class A shares of another Pioneer Fund or purchase Class A share of another Pioneer Fund without paying any sales charge. Seventh, the Trustees also considered the differences in the investment policies of the two Funds, particularly Pioneer Bond Fund's ability to invest in securities with longer maturities than your Safeco Fund. While this may result in Pioneer Bond Fund having greater volatility of net asset value than your Safeco Fund, the Trustees believe that the factors in favor of the Reorganization mitigate this risk. Pioneer and Symetra will pay all out of pocket expenses of the Safeco Funds and the Pioneer Funds associated with the Reorganizations, including, but not limited to: (1) the expenses associated with the preparation, printing and mailing of any shareholder communications, including this joint Proxy Statement/Prospectus, and any filings with the SEC and other governmental authorities in connection with the Reorganizations; (2) the fees and expenses of any proxy solicitation firm retained in connection with the Reorganizations; (3) the legal fees and expenses incurred by the Safeco Funds in connection with the Reorganizations; and (4) the Trustee fees and out of pocket expenses incurred as a result of the Reorganizations. The Trustees considered that Pioneer and Symetra will benefit from the Reorganization. See "Certain Agreements between Pioneer and Symetra." The Board of Trustees of Pioneer Bond Fund also considered that the Reorganization presents an excellent opportunity for the Pioneer Bond 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 Pioneer Bond Fund and its shareholders. 50 CAPITALIZATION The following table sets forth the capitalization of each Fund as of September 30, 2004, and the pro forma capitalization of the combined Fund as of September 30, 2004.

The table should not be relied upon to determine the amount of Pioneer Bond 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 Safeco Fund. Similarly, the Board of Trustees of Pioneer Bond Fund, including its Independent Trustees, approved the Reorganization. They also determined that the Reorganization is in the best interests of Pioneer Bond Fund. The Trustees recommend that the shareholders of your Safeco Fund vote FOR the proposal to approve the Agreement and Plan of Reorganization. 51 Safeco Intermediate-Term Municipal Bond Fund and Pioneer Tax Free Income 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 should read carefully the entire Proxy Statement/Prospectus, including the Agreement and Plan of Reorganization attached as EXHIBIT A-1 because they contain details that are not in the summary. The Investor Class shares to be issued in the Reorganization will convert to Class A shares after two years. Class A shares will have higher expenses per share than Investor Class shares due to the Rule 12b-1 Plan. In addition, although Pioneer has agreed to limit the expenses attributable to Investor Class shares, Pioneer is not required to limit the expenses attributable to Class A shares. In the table below, if a row extends across the entire table, the policy disclosed applies to both your Safeco Fund and the Pioneer Fund.

The market value of a fixed income security tends to be more volatile the longer the maturity of such security. Since Pioneer Tax Free Income Fund can invest in securities of longer maturity than your Safeco Fund, an investment in Pioneer Tax Free Income Fund may have correspondingly greater 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 debt securities in the Fund's portfolio 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 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 Fund's investment 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 Funds' tax-exempt securities are generally exempt from regular federal income 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 whether an alternative minimum tax applies to you and about state and local taxes on Fund distributions. 60 The Investor Class shares to be issued in the Reorganization will convert to Class A shares after two years. Class A shares will have higher expenses per share than Investor Class shares due to the Rule 12b-1 Plan. In addition, although Pioneer has agreed to limit the expenses attributable to Investor Class shares, Pioneer is not required to limit the expenses attributable to Class A shares. 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.

Pioneer Tax Free Income Fund's Investor Class shares will not be outstanding prior to the closing of the Reorganization and consequently have no performance history. However, the performance record of the Investor Class would be modestly higher than the performance of Class A shares due to the lower expenses applicable to the Investor Class shares. The most recent portfolio manager's discussion of each Fund's performance is attached as Exhibit D. 63 The Funds' Fees and Expenses Shareholders of both Funds pay various fees and expenses, either directly or indirectly.

In addition, shareholders of your Safeco Fund who own shares in their own name (i.e., not in the name of a broker or other intermediary) and maintain such account as of the closing of the Reorganization may purchase Class A shares of Pioneer Tax Free Income Fund or of any fund in the Pioneer family of funds through such account in the future without paying this sales charge. (2) As described above, SAM had contractually agreed to reimburse Safeco Intermediate-Term Municipal Bond Fund for certain operating expenses (but not all of the operating expenses of the Fund) that exceeded the rate of 0.40% per annum of the Fund's average daily net assets. This arrangement included all Fund operating expenses except management fees, Rule 12b-1 fees, brokerage commissions, interest, and extraordinary expenses. In 2003, SAM began voluntarily reimbursing the Fund to the extent that its total expenses exceeded the rate of 0.85% per annum of the Fund's average daily net assets for Class A shares, 1.60% per annum for Class B and Class C shares, and 0.70% per annum for Investor Class shares. The above table reflects "contractual" expense reimbursements from SAM, if any, but does not reflect "voluntary" expense reimbursements by SAM. (3) Pioneer has agreed that through the second anniversary of the closing of the Reorganization, Pioneer will limit the expenses (excluding extraordinary expenses) of the Investor Class shares of Pioneer Tax Free Income Fund to 0.70% of average daily net assets. (4) There is a higher charge for international wire redemptions, which may vary by country or dollar amount. (5) A low balance fee is charged once in year in December for accounts with balances under $1,000 in your Safeco Fund. (6) Purchases of $1,000,000 or more of Class A shares of your Safeco Fund are not subject to a front-end sales charge, but a 1.00% deferred sales charge will apply to redemptions made in the first twelve months except with respect to participant-directed redemptions from qualified retirement plans. (7) The contingent deferred sales charge on Class B shares of your Safeco Fund reduces to zero after five years from purchase, and the Class B shares convert to Class A shares at that time. (8) The contingent deferred sales charge on Class C shares applies only to redemptions made in the first twelve months after purchase. (9) The Investor Class shares to be issued in the Reorganization will convert to Class A shares after two years. Class A shares will have higher expenses per share than Investor Class shares due to the Rule 12b-1 Plan. In addition, although Pioneer has agreed to limit 64 the expenses attributable to Investor Class shares, Pioneer is not required to limit the expenses attributable to Class A shares. Class A shares do not currently have an expense limitation and may be subject to higher total operating expenses. 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, (e) the expense limitations are in effect for five years for Safeco Intermediate-Term Municipal Bond Fund and two years for Pioneer Tax Free Income Fund and (f) and the Investor Class shares of Pioneer Tax Free Income Fund convert to Class A shares after two years. 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, SAM, the investment adviser to the Fund until August 2, 2004, was acquired by Symetra. Symetra informed the Trustees that it did not intend to continue to provide investment advisory services to the Safeco Funds. Consequently, a change in your Safeco Fund's investment adviser was necessary. Second, the historical investment performance of Pioneer Tax Free Income Safeco Fund and your Safeco Fund are comparable. For the one, five and ten year periods ended June 30, 2004, Class A shares of Pioneer Tax Free Income Fund had an average annual return of 1.55%, 4.84% and 5.53%, respectively, compared to an average annual return of the Class A shares and Investor Class shares of - -3.82% and -0.27% (one year), 4.13% and 4.94% (five years) and 4.84% and 5.25% (ten years), respectively, during the same period. In addition, the Trustees considered the track record of Pioneer in managing equity and fixed income mutual funds. 65 Third, the resources of Pioneer. At June 30, 2004, Pioneer managed over 62 investment companies and accounts with approximately $35 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 June 30, 2004, assets under management of UniCredito Italiano S.p.A. were approximately $151 billion worldwide. Shareholders of your Safeco 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 62 funds, including domestic and international equity and fixed income funds and a money market fund that will be available to your Safeco 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 Tax Free Income Fund's lower operating expenses and Pioneer's commitment until the second anniversary of the Reorganization to limit the expenses (excluding extraordinary expenses) of the Investor Class of Pioneer Tax Free Income Fund to 0.70% of average daily net assets. The estimated expenses of the Investor Class shares of Pioneer Tax Free Income Fund are below both the gross expenses and expenses net of expense reimbursement of each class of shares of your Safeco Fund. Although you will experience higher expenses once the Investor Class shares convert to Class A shares after two years, your expenses will remain the same until the second anniversary of the Reorganization. Fifth, the substantially larger size of Pioneer Tax Free Income Fund offers greater opportunity for diversification of the investment portfolio, which should help to reduce risks. Sixth, shareholders who own shares in their name as of the closing of the Reorganization (i.e., not in the name of a broker or other intermediary) and maintain their account may purchase additional Class A shares of the corresponding Pioneer Fund through such account in the future or may exchange those shares for Class A shares of another Pioneer Fund or purchase Class A share of another Pioneer Fund without paying any sales charge. Seventh, the Trustees also considered the differences in the investment policies of the two Funds, particularly Pioneer Tax Free Income Fund's ability to invest in securities with longer maturities than your Safeco Fund. While this may result in Pioneer Tax Free Income Fund having greater volatility of net asset value than your Safeco Fund, the Trustees believe that the factors in favor of the Reorganization mitigate this risk. Pioneer and Symetra will pay all out of pocket expenses of the Safeco Funds and the Pioneer Funds associated with the Reorganizations, including, but not limited to: (1) the expenses associated with the preparation, printing and mailing of any shareholder communications, including this joint Proxy Statement/Prospectus, and any filings with the SEC and other governmental authorities in connection with the Reorganizations; (2) the fees and expenses of any proxy solicitation firm retained in connection with the Reorganizations; (3) the legal fees and expenses incurred by the Safeco Funds in connection with the Reorganizations; and (4) the Trustee fees and out of pocket expenses incurred as a result of the Reorganizations. The Trustees considered that Pioneer and Symetra will benefit from the Reorganization. See "Certain Agreements between Pioneer and Symetra." The Board of Trustees of Pioneer Tax Free Income Fund also considered that the Reorganization presents an excellent opportunity for the Pioneer Tax Free Income 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 Pioneer Tax Free Income Fund and its shareholders. 66 CAPITALIZATION The following table sets forth the capitalization of each Fund, as of September 30, 2004, and the pro forma capitalization of the combined Fund as of September 30, 2004.

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 Safeco Fund. Similarly, the Board of Trustees of Pioneer Tax Free Income Fund, including its Independent Trustees, approved the Reorganization. They also determined that the Reorganization is in the best interests of Pioneer Tax Free Income Fund. The Trustees recommend that the shareholders of your Safeco Fund vote FOR the proposal to approve the Agreement and Plan of Reorganization. 67 Safeco Intermediate-Term U.S. Government Fund and Pioneer America Income Trust 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 they contain details that are not in the summary. The Investor Class shares to be issued in the Reorganization will convert to Class A shares after two years. Class A shares will have higher expenses per share than Investor Class shares due to the Rule 12b-1 Plan. In addition, although Pioneer has agreed to limit the expenses attributable to Investor Class shares, Pioneer is not required to limit the expenses attributable to Class A shares. In the table below, if a row extends across the entire table, the policy disclosed applies to both your Safeco Fund and the Pioneer Fund.

The market value of fixed income securities tends to be more volatile the greater the maturity of the security. Pioneer America Income Trust can invest in securities of greater average maturity than your Safeco Fund and consequently may have greater risk. However, your Safeco Fund may invest in U.S. government securities that are not backed by the full faith and credit of the U.S. Treasury, and consequently have an element of credit risk that is not present in Pioneer America Income Trust. Generally, however, 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 debt securities in the Fund's portfolio to decline o During periods of declining interest rates, the issuer of a security may exercise its option to prepay principal earlier than scheduled, forcing the Fund to reinvest in lower yielding securities. This is known as call or prepayment risk o During periods of rising interest rates, the average life of certain types of securities may be extended because of slower than expected principal payments. This may lock in a below market interest rate, increase the security's duration (the estimated period until the security is paid in full) and reduce the value of the security. This is known as extension risk o Pioneer's judgment about the attractiveness, relative value or potential appreciation of a particular sector, security or investment strategy proves to be incorrect To the extent the Fund invests significantly in mortgage-backed securities, its exposure to prepayment and extension risks may be greater than other investments in fixed income securities. Although mortgage pools issued by U.S. agencies are guaranteed with respect to payments of principal and interest, such guarantee does not apply to losses resulting from declines in the market value of such securities. 75 The Investor Class shares to be issued in the Reorganization will convert to Class A shares after two years. Class A shares will have higher expenses per share than Investor Class shares due to the Rule 12b-1 Plan. In addition, although Pioneer has agreed to limit the expenses attributable to Investor Class shares, Pioneer is not required to limit the expenses attributable to Class A shares. 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.

However, the performance record of the Investor Class would be modestly higher than the performance of Class A shares due to the lower expenses applicable to the Investor Class. The most recent portfolio manager's discussion of each Fund's performance is attached as Exhibit D. 78 The Funds' Fees and Expenses Shareholders of both Funds pay various fees and expenses, either directly or indirectly. The tables below show the fees and expenses that you would pay if you were to buy and hold shares of each Fund. The expenses in the tables appearing below are based on (i) for your Safeco Fund, the expenses of your Safeco Fund for the period ended December 31, 2003 and (ii) for Pioneer America Income Trust, the expenses of Pioneer America Income Trust for the period ended December 31, 2003. Future expenses for all share classes may be greater or less.

In addition, shareholders of your Safeco Fund who own shares in their own name (i.e., not in the name of a broker or other intermediary) and maintain such account as of the closing of the Reorganization may purchase Class A shares of Pioneer America Income Trust or of any fund in the Pioneer family of funds through such account in the future without paying this sales charge. (2) As described above, SAM had contractually agreed to reimburse Safeco Intermediate-Term U.S. Government Bond Fund for certain Fund operating expenses (but not all of the operating expenses of the Fund) that exceeded the rate of 0.40% per annum of the Fund's average daily net assets. This arrangement included all Fund operating expenses except management fees, Rule 12b-1 fees, brokerage commissions, interest, and extraordinary expenses. In 2003, SAM began voluntarily reimbursing the Fund to the extent that its total expenses exceeded the rate of 0.99% per annum of the Fund's average daily net assets for Class A shares, 1.74% per annum for Class B and Class C shares, and 0.74% per annum for Investor Class shares. The above table reflects "contractual" expense reimbursements from SAM, if any, but does not reflect "voluntary" expense reimbursements by SAM. (3) Pioneer has agreed that through the second anniversary of the closing of the Reorganization, Pioneer will limit the expenses (excluding extraordinary expenses) of the Investor Class shares of Pioneer America Income Trust to 0.74% of average daily net assets. (4) There is a higher charge for international wire redemptions, which may vary by country or dollar amount. (5) A low balance fee is charged once in year in December for accounts with balances under $1,000 in your Safeco Fund. (6) Purchases of $1,000,000 or more of Class A shares of your Safeco Fund are not subject to a front-end sales charge, but a 1.00% deferred sales charge will apply to redemptions made in the first twelve months except with respect to participant-directed redemptions from qualified retirement plans. (7) The contingent deferred sales charge on Class B shares of your Safeco Fund reduces to zero after five years from purchase, and the Class B shares convert to Class A shares at that time. (8) The contingent deferred sales charge on Class C shares applies only to redemptions made in the first twelve months after purchase. 79 (9) The Investor Class shares to be issued in the Reorganization will convert to Class A shares after two years. Class A shares will have higher expenses per share than Investor Class shares due to the Rule 12b-1 Plan. In addition, although Pioneer has agreed to limit the expenses attributable to Investor Class shares, Pioneer is not required to limit the expenses attributable to Class A shares. 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, (e) the expense limitations are in effect for five years for Safeco Intermediate-Term U.S. Government Fund and two years for Pioneer America Income Trust and (f) and the Investor Class shares of Pioneer America Income Trust convert to Class A shares after two years. The examples are for comparison purposes only and are not a representation of either Fund's actual expenses or returns, either past or future.

Safeco Intermediate-Term U.S. Government Fund is a series of the Safeco Taxable Bond Trust, a Delaware statutory trust. The governing instrument of Safeco Taxable Bond Trust is its Trust Instrument (the "Trust Instrument"). The Trustees of the Safeco Taxable Bond Trust are responsible for the management and supervision of Safeco Intermediate-Term U.S. Government Fund. o SHARE CAPITAL AND CLASSES. The Trust Instrument of Safeco Taxable Bond Trust permits the Trustees to issue an unlimited number of full and fractional shares of beneficial interest of Safeco Intermediate-Term U.S. Government Fund without par value. As of the date of this Proxy Statement/Prospectus, the Trustees have authorized shares of Safeco Intermediate-Term U.S. Government Fund and have authorized the issuance of four classes of shares of Safeco Intermediate-Term U.S. Government Fund, designated as Class A, Class B, Class C and Investor Class shares. The shares of each class of Safeco Intermediate-Term U.S. Government Fund represent an equal proportionate interest in the aggregate net assets attributable to that class of the Fund. Holders of each class of shares have certain exclusive voting rights on matters relating to their respective distribution plans. The different classes of Safeco Intermediate-Term U.S. Government Fund may bear different expenses relating to the cost of holding shareholder meetings necessitated by the exclusive voting rights of any class of shares. In the event of liquidation, shareholders of each class are entitled to share pro rata in the net assets of their Fund available for distribution to these shareholders. Shares of each class entitle their holders to one vote per share, are freely transferable and have no preemptive, subscription or conversion rights. o MEETINGS. Under Delaware law, Safeco Taxable Bond Trust is not required to hold annual shareholder meetings for any Fund. Unless otherwise required by the Investment Company Act, the Fund has no intention of holding annual meetings of shareholders. Pursuant to the Trust Instrument, shareholders have power to vote only on certain matters, including (a) the election and removal of Trustees; (b) approval of any investment management agreement; (c) termination of the Safeco Taxable Bond Trust; (d) certain amendments to the Trust Instrument; and (e) such additional matters relating to the Trust as may be required by law or as the Trustees may consider desirable. o LIABILITY OF SHAREHOLDERS. Delaware law affords shareholders of a Delaware statutory trust with the same protections afforded stockholders of a Delaware corporation, which means shareholders are not generally subject to liability for the debts or obligations of the statutory trust unless the entity's trust instrument provides otherwise. The Trust Instrument of the Safeco Taxable Bond Trust contains an express disclaimer of shareholder liability for acts, obligations or affairs of Safeco Intermediate-Term U.S. Government Fund and provides for indemnification out of the Fund's assets for all losses and expenses of any shareholder held personally liable for reason of being or having been a shareholder. Characteristics of Pioneer America Income Trust (a Massachusetts business trust) o GOVERNANCE AND MANAGEMENT. Pioneer America Income Trust is a Massachusetts business trust. The governing instrument of Pioneer America Income Trust is its Agreement and Declaration of Trust ("Declaration of Trust"). The business of Pioneer America Income Trust is managed under the direction of its Board of Trustees. The Trustees, in addition to viewing the actions of the Pioneer America Income Trust's investment adviser, decide upon matters of general policy at their regular meetings. The officers of Pioneer America Income Trust supervise its business operations. o SHARES AND CLASSES. Pioneer America Income Trust is authorized to issue shares of beneficial interest and to increase or decrease the aggregate number of shares of beneficial interest or the number of shares of any class that the Fund has authority to issue. Each share is entitled to one vote on all questions relating to the Fund, and each share is entitled to participate equally in dividends and capital gains distributions and in the residual assets of the respective class in the event of liquidation. o MEETINGS. Under Massachusetts law, Pioneer America Income Trust, as a registered open-end investment company, is not required to hold annual shareholder meetings. Unless otherwise required by the Investment Company Act, the Pioneer America Income Trust has no intention of holding annual meetings of shareholders. Pursuant to the Declaration of Trust, special meetings of shareholders may be called at any time by the Chairman, President or by the Board of Trustees or by the secretary upon the written request of shareholders entitled to cast at least 25% of the votes entitled to be cast at such meeting, provided that such request shall state the purposes of such meeting and the matters proposed to be acted on. o LIABILITY OF SHAREHOLDERS. Shareholders of a Massachusetts business trust may, under certain circumstances, be held personally liable for the obligations of the trust. However, the Declaration of Trust contains an express disclaimer of shareholder liability for acts or obligations of the Pioneer America Income Trust or any series of the Pioneer America Income Trust and provides 81 that notice of such disclaimer may be given in each agreement, obligation or instrument entered into or executed by the Pioneer America Income Trust or its Trustees. Moreover, the Declaration of Trust provides for the indemnification out of Pioneer America Income Trust property of any shareholders held personally liable for any obligations of the Pioneer America Income Trust or any series of the Pioneer America Income Trust. The Declaration of Trust also provides that the Pioneer America Income Trust shall, upon request, assume the defense of any claim made against any shareholder for any act or obligation of the Pioneer America Income Trust and satisfy any judgment thereon. Thus, the risk of a shareholder incurring financial loss beyond his or her investment because of shareholder liability would be limited to circumstances in which the fund itself will be unable to meet its obligations. In light of the nature of the Pioneer America Income Trust's business and the nature and amount of its assets, the possibility of the Pioneer America Income Trust's liabilities exceeding its assets, and therefore a shareholder's risk of personal liability, is remote. Reasons for the Proposed Reorganization The Trustees believe that the proposed Reorganization is in the best interests of Safeco Intermediate-Term U.S. Government Fund. The Trustees considered the following matters, among others, in approving the proposal. First, SAM, the investment adviser to the Safeco Fund until August 2, 2004, was acquired by Symetra. Symetra informed the Trustees that it did not intend to continue to provide investment advisory services to the Safeco Funds. Consequently, a change in your Safeco Fund's investment adviser was necessary. Second, the performance of Pioneer America Income Trust is generally consistent with the historical investment performance of your Safeco Fund. For the one, five and ten year periods ended June 30, 2004, Class A shares of Pioneer America Income Trust had an average annual return of -0.37%, 5.64%, and 5.97%, respectively, compared to an average annual return of the Class A shares and Investor Class shares of -4.56% and -0.73% (one year), 4.73% and 5.73% (five years) and 5.79% and 6.29% (ten years), 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 June 30, 2004, Pioneer managed over 62 investment companies and accounts with approximately $35 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 June 30, 2004, assets under management of UniCredito Italiano S.p.A. were approximately $151 billion worldwide. Shareholders of your Safeco 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 62 funds, including domestic and international equity and fixed income funds and a money market fund that will be available to your Safeco 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 lower operating expenses and Pioneer's commitment until the second anniversary of the Reorganization to limit the expenses (excluding extraordinary expenses) of the Investor Class of Pioneer America Income Trust to 0.74% of average daily net assets. The estimated expenses of the Investor Class of Pioneer America Income Trust are below both the gross expenses and expenses net of contractual expense reimbursement of the end class of shares of your Safeco Fund. Although you will experience higher expenses once the Investor Class shares convert to Class A shares after two years, based upon the Class A expense ratio of Pioneer America Income Trust for the most recent fiscal year, Pioneer America Income Trust's expenses were lower than the gross and net expense ratio of each class of shares of your Safeco Fund. While there are some differences between the policies of the two Funds, the Trustees believe that the two Funds represent substantially equivalent investments. Fifth, the substantially larger size of Pioneer America Income Trust offers greater opportunity for diversification of the investment portfolio, which should help to reduce risks. Sixth, shareholders who own shares in their name as of the closing of the Reorganization (i.e., not in the name of a broker or other intermediary) and maintain their account may purchase additional Class A shares of the corresponding Pioneer Fund through such account in the future or may exchange those shares for Class A shares of another Pioneer Fund or purchase Class A share of another Pioneer Fund without paying any sales charge. Seventh, the Investor Class shares of Pioneer America Income Trust received in the Reorganization will provide Safeco Intermediate-Term U.S. Government Fund shareholders with exposure to substantially the same investment product as they currently have. Pioneer and Symetra will pay all out of pocket expenses of the Safeco Funds and the Pioneer Funds associated with the Reorganizations, including, but not limited to: (1) the expenses associated with the preparation, printing and mailing of any shareholder communications, including this joint Proxy Statement/Prospectus, and any filings with the SEC and other governmental authorities in connection with the 82 Reorganizations; (2) the fees and expenses of any proxy solicitation firm retained in connection with the Reorganizations; (3) the legal fees and expenses incurred by the Safeco Funds in connection with the Reorganizations; and (4) the Trustee fees and out of pocket expenses incurred as a result of the Reorganizations. The Trustees considered that Pioneer and Symetra will benefit from the Reorganization. See "Certain Agreements between Pioneer and Symetra." The Board of Trustees of Pioneer America Income Trust also considered that the Reorganization presents an excellent opportunity for the Pioneer America Income Trust 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 Pioneer America Income Trust and its shareholders.

The table should not be relied upon to determine the amount of Pioneer America Income Trust'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 Safeco Fund. Similarly, the Board of Trustees of Pioneer America Income Trust, including its Independent Trustees, approved the Reorganization. They also determined that the Reorganization is in the best interests of Pioneer America Income Trust. The Trustees recommend that the shareholders of your Safeco Fund vote FOR the proposal to approve the Agreement and Plan of Reorganization. 83 Safeco Money Market Fund and Pioneer Cash Reserves 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 they contain details that are not in the summary. The Investor Class shares to be issued in the Reorganization will convert to Class A shares after two years. Class A shares will have higher expenses per share than Investor Class shares due to the Rule 12b-1 Plan. In addition, although Pioneer has agreed to limit the expenses attributable to Investor Class shares, Pioneer is not required to limit the expenses attributable to Class A shares. In the table below, if a row extends across the entire table, the policy disclosed applies to both your Safeco Fund and the Pioneer Fund.

Even though the Funds seek to maintain a $1 share price, you could lose money on your investment or the Fund could fail to generate high current income 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 The investment adviser's judgment about the credit quality, attractiveness or relative value of a particular security proves to be incorrect Investing in non-U.S. issuers may involve unique risks compared to investing in securities of U.S. issuers. These risks may include: o Inadequate financial information o Smaller, less liquid and more volatile markets o Political and economic upheavals The Investor Class shares to be issued in the Reorganization will convert to Class A shares after two years. Class A shares will have higher expenses per share than Investor Class shares due to the Rule 12b-1 Plan. In addition, although Pioneer has agreed to limit the expenses attributable to Investor Class shares, Pioneer is not required to limit the expenses attributable to Class A shares. 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 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.

However, the performance record of the Investor Class would be modestly higher than the performance of Class A, B and C shares due to the lower expenses applicable to the Investor Class. The most recent portfolio manager's discussion of each Fund's performance is attached as Exhibit D. 92 The Funds' Fees and Expenses Shareholders of both Funds pay various fees and expenses, either directly or indirectly. The tables below show the fees and expenses that you would pay if you were to buy and hold shares of each Fund. The expenses in the tables appearing below are based on (i) for your Safeco Fund, the expenses of your Safeco Fund for the period ended December 31, 2003 and (ii) for Pioneer Cash Reserves Fund, the expenses of Pioneer Cash Reserves Fund for the period ended December 31, 2003. Future expenses for all share classes may be greater or less.

In addition, shareholders of your Safeco Fund who own shares in their own name (i.e., not in the name of a broker or other intermediary) and maintain such account as of the closing of the Reorganization may purchase Class A shares of Pioneer Cash Reserves Fund or of any fund in the Pioneer family of funds through such account in the future without paying this sales charge. (2) As described above, SAM had contractually agreed to reimburse Safeco Money Market Fund for certain Fund operating expenses (but not all of the operating expenses of the Fund) that exceeded the rate of 0.30% per annum of the Fund's average daily net assets. This arrangement included all Fund operating expenses except management fees, Rule 12b-1 fees, brokerage commissions, interest, and extraordinary expenses. (3) Pioneer has agreed that through the second anniversary of the closing of the Reorganization, Pioneer will limit the expenses (excluding extraordinary expenses) of the Investor Class shares of Pioneer Cash Reserves Fund to 0.71% of average daily net assets. (4) There is a higher charge for international wire redemptions, which may vary by country or dollar amount. (5) A low balance fee is charged once in year in December for accounts with balances under $1,000 in your Safeco Fund. (6) A contingent deferred sales charge may apply if you redeem Class B shares of your Safeco Fund that were purchased by exchange from another fund. (7) A 1.00% contingent deferred sales charge may apply if, within the first twelve months of the initial purchase, you redeem Class C shares that were purchased by exchange from another fund (8) The Investor Class shares to be issued in the Reorganization will convert to Class A shares after two years. Class A shares will have higher expenses per share than Investor Class shares due to the Rule 12b-1 Plan. In addition, although Pioneer has agreed to limit the expenses attributable to Investor Class shares, Pioneer is not required to limit the expenses attributable to Class A shares. Class A shares do not currently have an expense limitation and may be subject to higher total operating expenses. 93 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, (e) the expense limitations are in effect for five years for Safeco Money Market Fund and two years for Pioneer Cash Reserves Fund and (f) and the Investor Class shares of Pioneer Cash Reserves Fund convert to Class A shares after two years. 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, SAM, the investment adviser to the Safeco Fund until August 2, 2004, was acquired by Symetra. Symetra informed the Trustees that it did not intend to continue to provide investment advisory services to the Safeco Funds. Consequently, a change in your Safeco Fund's investment adviser was necessary. Second, the investment performance of Pioneer Cash Reserves Fund is comparable to the historical investment performance of your Safeco Fund. For the one, five and ten year periods ended June 30, 2004, Class A shares of Pioneer Cash Reserves Fund had an average annual return of 0.12%, 2.50%, and 3.60%, respectively, compared to an average annual return of the Class A shares and Investor Class shares of 0.42% and 0.51% (one year), 2.82% and 2.86% (five years), and 3.82% and 3.85% (ten years) 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 June 30, 2004, Pioneer managed over 62 investment companies and accounts with approximately $35 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 June 30, 2004, 94 assets under management of UniCredito Italiano S.p.A. were approximately $151 billion worldwide. Shareholders of your Safeco Fund would become part of a significantly larger family of funds that offers a more diverse array of investment options and enhanced shareholders account options. The Pioneer family of mutual funds offers over 62 funds, including domestic and international equity and fixed income funds and a money market fund that will be available to your Safeco 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's commitment until the second anniversary of the Reorganization to limit the expenses (excluding extraordinary expenses) of the Investor Class of Pioneer Cash Reserves Fund to 0.71% of average daily net assets. Although you will experience higher expenses once the Investor Class shares convert to Class A shares after two years, your expenses will remain the same until the second anniversary of the Reorganization. Fifth, shareholders who own shares in their name as of the closing of the Reorganization (i.e., not in the name of a broker or other intermediary) and maintain their account may purchase additional Class A shares of the corresponding Pioneer Fund through such account in the future or may exchange those shares for Class A shares of another Pioneer Fund or purchase Class A share of another Pioneer Fund without paying any sales charge. Sixth, the Investor Class shares of Pioneer Cash Reserves Fund received in the Reorganization will provide Safeco Money Market Fund shareholders with exposure to substantially the same investment product as they currently have. Pioneer and Symetra will pay all out of pocket expenses of the Safeco Funds and the Pioneer Funds associated with the Reorganizations, including, but not limited to: (1) the expenses associated with the preparation, printing and mailing of any shareholder communications, including this joint Proxy Statement/Prospectus, and any filings with the SEC and other governmental authorities in connection with the Reorganizations; (2) the fees and expenses of any proxy solicitation firm retained in connection with the Reorganizations; (3) the legal fees and expenses incurred by the Safeco Funds in connection with the Reorganizations; and (4) the Trustee fees and out of pocket expenses incurred as a result of the Reorganizations. The Trustees considered that Pioneer and Symetra will benefit from the Reorganization. See "Certain Agreements between Pioneer and Symetra." The Board of Trustees of Pioneer Cash Reserves Fund also considered that the Reorganization presents an excellent opportunity for the Pioneer Cash Reserves 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 Pioneer Cash Reserves Fund and its shareholders. 95 CAPITALIZATION The following table sets forth the capitalization of each Fund, as of June 30, 2004, and the pro forma combined Fund as of June 30, 2004.

The table should not be relied upon to determine the amount of Pioneer Cash Reserves 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 Safeco Fund. Similarly, the Board of Trustees of Pioneer Cash Reserves Fund, including its Independent Trustees, approved the Reorganization. They also determined that the Reorganization is in the best interests of Pioneer Cash Reserves Fund. The Trustees recommend that the shareholders of your Safeco Fund vote FOR the proposal to approve the Agreement and Plan of Reorganization. 96 Safeco Municipal Bond Fund and Pioneer Municipal Bond 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 they contain details that are not in the summary. The Investor Class shares to be issued in the Reorganization will convert to Class A shares after two years. Class A shares will have higher expenses per share than Investor Class shares due to the Rule 12b-1 Plan. In addition, although Pioneer has agreed to limit the expenses attributable to Investor Class shares, Pioneer is not required to limit the expenses attributable to Class A shares. In the table below, if a row extends across the entire table, the policy disclosed applies to both your Safeco Fund and the Pioneer Fund.

Pioneer Municipal Bond 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. - ----------------------------------------------------------------------------------------------------------------------------------- 100 - ----------------------------------------------------------------------------------------------------------------------------------- Safeco Municipal Bond Fund Pioneer Municipal Bond Fund - ----------------------------------------------------------------------------------------------------------------------------------- Each Fund may invest in obligations of the U.S. government, its agencies or instrumentalities or in qualified repurchase agreements, the net interest on which is taxable for federal income tax purposes.

Even though each Fund seeks to maintain a $1 share price, you could lose money on your investment or the Fund could fail to generate high current income 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 105 o The investment adviser's judgment about the credit quality, attractiveness or relative value of a particular security proves to be incorrect 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 Investing in mutual fund shares is not the same as making a bank deposit. Your investment is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. You could lose money by investing in either Fund. The Investor Class shares to be issued in the Reorganization will convert to Class A shares after two years. Class A shares will have higher expenses per share than Investor Class shares due to the Rule 12b-1 Plan. In addition, although Pioneer has agreed to limit the expenses attributable to Investor Class shares, Pioneer is not required to limit the expenses attributable to Class A shares.

In addition, shareholders of your Safeco Fund who own shares in their own name (i.e., not in the name of a broker or other intermediary) and maintain such account as of the closing of the Reorganization may purchase Class A shares of Pioneer Municipal Bond Fund or of any fund in the Pioneer family of funds through such account in the future without paying this sales charge. (2) As described above, SAM had contractually agreed to reimburse Safeco Municipal Bond Fund for certain Fund operating expenses (but not all of the operating expenses of the Fund) that exceeded the rate of 0.40% per annum of the Fund's average daily net assets. This arrangement included all fund operating expenses except management fees, Rule 12b-1 fees, brokerage commissions, interest, and extraordinary expenses. (3) Pioneer has agreed that through the second anniversary of the closing of the Reorganization, Pioneer will limit the expenses (excluding extraordinary expenses) of the Investor Class shares of Pioneer Municipal Bond Fund to 0.62% of average daily net assets. (4) There is a higher charge for international wire redemptions, which may vary by country or dollar amount. (5) A low balance fee is charged once each year in December for accounts with balances under $1,000 in your Safeco Fund. (6) Purchases of $1,000,000 or more of Class A shares of your Safeco Fund are not subject to a front-end sales charge, but a 1.00% deferred sales charge will apply to redemptions made in the first twelve months except with respect to participant-directed redemptions from qualified retirement plans. (7) The contingent deferred sales charge on Class B shares of your Safeco Fund reduces to zero after six years from purchase, and the Class B shares convert to Class A shares at that time. (8) The contingent deferred sales charge on Class C shares applies only to redemptions made in the first twelve months after purchase. (9) The Investor Class shares to be issued in the Reorganization will convert to Class A shares after two years. Class A shares will have higher expenses per share than Investor Class shares due to the Rule 12b-1 Plan. In addition, although Pioneer has agreed to limit the expenses attributable to Investor Class shares, Pioneer is not required to limit the expenses attributable to Class A shares. 108 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, (e) the expense limitations are in effect for five years for Safeco Municipal Bond Fund and two years for Pioneer Municipal Bond Fund and (f) and the Investor Class shares of Pioneer Municipal Bond Fund convert to Class A shares after two years. 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, SAM, the investment adviser to the Fund until August 2, 2004, was acquired by Symetra. Symetra informed the Trustees that it did not intend to continue to provide investment advisory services to the Safeco Funds. Consequently, a change in your Safeco Fund's investment adviser was necessary. Second, the significant experience and resources of Pioneer in managing portfolios of tax exempt securities. At September 30, 2004, Pioneer Managed Portfolio of tax exempt securities with total assets of approximately $ 1.5 billion. Third, the resources of Pioneer. At June 30, 2004, Pioneer managed over 62 investment companies and accounts with approximately $35 billion in assets. Pioneer is part of the global asset management group of UniCredito Italiano S.p.A., one of the largest banking groups 109 in Italy, providing investment management and financial services to mutual funds, institutional and other clients. As of June 30, 2004, assets under management of UniCredito Italiano S.p.A. were approximately $151 billion worldwide. Shareholders of your Safeco 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 62 funds, including domestic and international equity and fixed income funds and a money market fund that will be available to your Safeco 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's commitment until the second anniversary of the Reorganization to limit the expenses (excluding extraordinary expenses) of the Investor Class of Pioneer Municipal Bond Fund to 0.62% of average daily net assets. This expense ratio is lower than both the gross expenses and expenses net of expense reimbursement of the Class A shares. Although you will experience higher expenses once the Investor Class shares convert to Class A shares after two years, your expenses will remain the same until the second anniversary of the Reorganization. Fifth, shareholders who own shares in their name as of the closing of the Reorganization (i.e., not in the name of a broker or other intermediary) and maintain their account may purchase additional Class A shares of the corresponding Pioneer Fund through such account in the future or may exchange those shares for Class A shares of another Pioneer Fund or purchase Class A share of another Pioneer Fund without paying any sales charge. Sixth, the Investor Class shares of Pioneer Municipal Bond Fund received in the Reorganization will provide Safeco Municipal Bond Fund shareholders with exposure to substantially the same investment product as they currently have. Pioneer and Symetra will pay all out of pocket expenses of the Safeco Funds and the Pioneer Funds associated with the Reorganizations, including, but not limited to: (1) the expenses associated with the preparation, printing and mailing of any shareholder communications, including this joint Proxy Statement/Prospectus, and any filings with the SEC and other governmental authorities in connection with the Reorganizations; (2) the fees and expenses of any proxy solicitation firm retained in connection with the Reorganizations; (3) the legal fees and expenses incurred by the Safeco Funds in connection with the Reorganizations; and (4) the Trustee fees and out of pocket expenses incurred as a result of the Reorganizations. The Trustees considered that Pioneer and Symetra will benefit from the Reorganization. See "Certain Agreements between Pioneer and Symetra." The Board of Trustees of Pioneer Municipal Bond Fund also considered that the Reorganization presents an excellent opportunity for the Pioneer Municipal Bond 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 Pioneer Municipal Bond Fund and its shareholders. 110 CAPITALIZATION The following table sets forth the capitalization of each Fund, as of September 30, 2004, and the pro forma combined Fund as of September 30, 2004.

The table should not be relied upon to determine the amount of Pioneer Municipal Bond 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 Safeco Fund. Similarly, the Board of Trustees of Pioneer Municipal Bond Fund, including its Independent Trustees, approved the Reorganization. They also determined that the Reorganization is in the best interests of Pioneer Municipal Bond Fund. The Trustees recommend that the shareholders of your Safeco Fund vote FOR the proposal to approve the Agreement and Plan of Reorganization. 111 Safeco Tax-Free Money Market Fund and Pioneer Tax Free Money Market 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 they contain details that are not in the summary. The Investor Class shares to be issued in the Reorganization will convert to Class A shares after two years.

In addition, shareholders of your Safeco Fund who own shares in their own name (i.e., not in the name of a broker or other intermediary) and maintain such account as of the closing of the Reorganization may purchase Class A shares of Pioneer Tax Free Money Market Fund or of any fund in the Pioneer family of funds through such account in the future without paying this sales charge. (2) As described above, SAM had contractually agreed to reimburse Safeco Tax-Free Money Market Fund for certain Fund operating expenses (but not all of the operating expenses of the Fund) that exceeded the rate of 0.30% per annum of the Fund's average daily net assets. This arrangement included all Fund operating expenses except management fees, Rule 12b-1 fees, brokerage commissions, interest, and extraordinary expenses. In 2003, SAM began voluntarily reimbursing the Fund to the extent that its total expenses exceeded the rate of 0.65% per annum of the Fund's average daily net assets for the Investor Class shares. The above table reflects "contractual" expense reimbursements from SAM, if any, but does not reflect "voluntary" expense reimbursements by SAM. (3) Pioneer has agreed that through the second anniversary of the closing of the Reorganization, Pioneer will limit the expenses (excluding extraordinary expenses) of the Investor Class shares of Pioneer Tax Free Money Market Fund to 0.65% of average daily net assets. (4) There is a higher charge for international wire redemptions, which may vary by country or dollar amount. (5) A low balance fee is charged once in year in December for accounts with balances under $1,000 in your Safeco Fund. (6) The Investor Class shares to be issued in the Reorganization will convert to Class A shares after two years. Class A shares will have higher expenses per share than Investor Class shares due to the Rule 12b-1 Plan. In addition, although Pioneer has agreed to limit the expenses attributable to Investor Class shares, Pioneer is not required to limit the expenses attributable to Class A shares. 122 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, (e) the expense limitations are in effect for five years for Safeco Tax-Free Money Market Fund and two years for Pioneer Tax Free Money Market Fund and (f) and the Investor Class shares of Pioneer Tax Free Money Market Fund convert to Class A shares after two years. 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, SAM, the investment adviser to the Safeco Fund until August 2, 2004, was acquired by Symetra. Symetra informed the Trustees that it did not intend to continue to provide investment advisory services to the Safeco Funds. Consequently, a change in your Safeco Fund's investment adviser was necessary. Second, the resources of Pioneer. At June 30, 2004, Pioneer managed over 62 investment companies and accounts with approximately $35 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 June 30, 2004, assets under management of UniCredito Italiano S.p.A. were approximately $151 billion worldwide. Shareholders of your Safeco 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 62 funds, including domestic and international equity and fixed income funds and a money market fund that will be available to your Safeco 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 has experience in managing many other money market and tax free portfolios. At September 30, 2004, Pioneer managed portfolios investing in tax exempt securities with aggregate assets of $1.5 billion and money market portfolios with assets of $531 million. Fourth, Pioneer and its affiliates have greater potential for increasing the size of your Safeco Fund due to Pioneer's experience in distributing mutual funds through a broader range of distribution channels than currently available to your Safeco Fund. Over the long-term, if this potential for a larger asset base is realized, it is expected to increase the portfolio management options available to the Fund. Fifth, Pioneer's commitment until the second anniversary of the Reorganization to limit the expenses (excluding extraordinary expenses) of the Investor Class of Pioneer Tax Free Money Market Fund to 0.65% of average daily net assets. This expense ratio is no higher than both the gross expenses and expenses net of expense reimbursement of the Investor Class shares of your Safeco Fund. Although you will experience higher expenses once the Investor Class shares convert to Class A shares after two years, your expenses will remain the same until the second anniversary of the Reorganization. Sixth, shareholders who own shares in their name as of the closing of the Reorganization (i.e., not in the name of a broker or other intermediary) and maintain their account may purchase additional Class A shares of the corresponding Pioneer Fund through such account 123 in the future or may exchange those shares for Class A shares of another Pioneer Fund or purchase Class A share of another Pioneer Fund without paying any sales charge. Seventh, the Investor Class shares of Pioneer Tax Free Money Market Fund received in the Reorganization will provide Safeco Tax-Free Money Market Fund shareholders with exposure to substantially the same investment product as they currently have. Pioneer and Symetra will pay all out of pocket expenses of the Safeco Funds and the Pioneer Funds associated with the Reorganizations, including, but not limited to: (1) the expenses associated with the preparation, printing and mailing of any shareholder communications, including this joint Proxy Statement/Prospectus, and any filings with the SEC and other governmental authorities in connection with the Reorganizations; (2) the fees and expenses of any proxy solicitation firm retained in connection with the Reorganizations; (3) the legal fees and expenses incurred by the Safeco Funds in connection with the Reorganizations; and (4) the Trustee fees and out of pocket expenses incurred as a result of the Reorganizations. The Trustees considered that Pioneer and Symetra will benefit from the Reorganization. See "Certain Agreements between Pioneer and Symetra." The Board of Trustees of Pioneer Tax Free Money Market Fund also considered that the Reorganization presents an excellent opportunity for the Pioneer Tax Free Money Market 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 Pioneer Tax Free Money Market Fund and its shareholders.

In particular, the Trustees determined that the Reorganization is in the best interests of your Safeco Fund. Similarly, the Board of Trustees of Pioneer Tax Free Money Market Fund, including its Independent Trustees, approved the Reorganization. They also determined that the Reorganization is in the best interests of Pioneer Tax Free Money Market Fund. The Trustees recommend that the shareholders of your Safeco Fund vote FOR the proposal to approve the Agreement and Plan of Reorganization. 124 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 December 10, 2004, unless your Safeco Fund and the corresponding Pioneer Fund agree in writing to a later date.

The corresponding Pioneer Fund will assume your Safeco Fund's liabilities that are included in the calculation of your Safeco 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 corresponding Pioneer Fund will issue to the corresponding Safeco Fund Investor Class shares with an aggregate net asset value equal to the net assets attributable to the corresponding Safeco Fund's shares. These shares will immediately be distributed to your Safeco Fund's shareholders in proportion to the relative net asset value of their holdings of your Safeco Fund's shares on the Closing Date. As a result, each Safeco Fund's shareholders will end up as Investor Class shareholders of the corresponding Pioneer Fund. o After the distribution of shares, your Safeco 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 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 Safeco 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 Pioneer Fund to consummate each Reorganization is subject to the satisfaction of certain conditions, including your Safeco Fund's performance of all of its obligations under the Plan, the receipt of certain documents and financial statements from your Safeco Fund and the receipt of all consents, orders and permits necessary to consummate the Reorganization (see Sections 7 and 8 of the Plan). The obligations of both Funds are subject to the approval of the Plan by the necessary vote of the outstanding shares of your Safeco Fund, in accordance with the provisions of your Trust's 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 federal income tax consequences of each Reorganization. (See Section 8.5 of the Plan). Termination of Agreement. The Board of either a Safeco Trust or the corresponding Pioneer Fund may terminate the Plan (even if the shareholders of your Safeco Fund have already approved it) at any time before the Reorganization Date, if that Board believes in good faith that proceeding with the Reorganization would no longer be in the best interests of shareholders. 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 Safeco Fund upon (1) the transfer of all of its assets to the Pioneer Fund as described in this Proxy Statement /Prospectus or (2) the distribution by your Safeco Fund of Pioneer Fund shares to your Safeco Fund's shareholders; o No gain or loss will be recognized by the Pioneer Fund upon the receipt of your Safeco Fund's assets solely in exchange for the issuance of Pioneer Fund shares to your Safeco Fund and the assumption of your Safeco Fund's liabilities by the corresponding Pioneer Fund; 125 o The basis of the assets of your Safeco Fund acquired by the corresponding Pioneer Fund will be the same as the basis of those assets in the hands of your Safeco Fund immediately before the transfer; o The tax holding period of the assets of your Safeco Fund in the hands of the corresponding Pioneer Fund will include your Safeco Fund's tax holding period for those assets; o You will not recognize gain or loss upon the exchange of your shares of your Safeco 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 Safeco Fund surrendered in 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 Safeco Fund surrendered in the exchange, provided that you held the shares of your Safeco 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 Safeco 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 Reorganization, including the applicability of any state, local or foreign tax laws. 126 PROPOSALS 2(a)-(h) APPROVAL OF INTERIM INVESTMENT ADVISORY AGREEMENT WITH PIONEER Background Having determined to recommend the Reorganizations, the Trustees appointed Pioneer as investment adviser to each Safeco Fund commencing August 2, 2004, until the closing of the Reorganizations given that Symetra had indicated that it did not wish to continue to offer investment advisory services to the Safeco Funds. Interim Investment Advisory Agreement Under the Investment Company Act, shareholders must approve any new investment advisory agreement for the Funds. However, Rule 15a-4 under the Investment Company Act permits your Trustees to appoint an adviser on an interim basis without prior shareholder approval if the new adviser agrees to provide such services on the same terms as the previous adviser and approves the investment advisory agreement with that adviser. An adviser may manage on such an interim basis for a period 150 days. Because Pioneer will be making the payment to Symetra discussed under "Background to the Reorganizations," any fees that Pioneer would be entitled to under the interim investment advisory agreement will be held in escrow by the Fund until shareholder approval of the agreement is obtained. If shareholders of a Safeco Fund do not approve the interim investment advisory agreement, Pioneer will not receive the fee under the current investment advisory agreement with SAM but instead will be paid a fee based upon Pioneer's cost in managing the Fund. During this period prior to the meeting, the Funds will be managed as separate Fund and will not be combined with a Pioneer Fund. During this period, you also will not be able to exchange your shares in a Fund for shares of a Pioneer Fund. If the appointment of Pioneer as interim investment adviser is not approved by December 30, 2004, Pioneer will no longer provide advisory services to the Funds, unless an extension of the 150 day period is permitted by a rule or independent position of the staff of the SEC. Reasons for Approving the Interim Investment Advisory Agreement and Board's Recommendation The Trustees recommend that the shareholders of the Safeco Funds approve the interim investment advisory agreements. In determining to appoint Pioneer as investment adviser on an interim basis, the Trustees considered many of the same factors on which the recommendation to approve the Reorganizations are based. These factors include: o SAM, the investment adviser to the Safeco Funds until August 2, 2004, was acquired by Symetra. Symetra informed the Trustees that it was not interested in continuing to provide investment advisory services to the Safeco Funds. Consequently, a change in your Safeco Fund's investment adviser was necessary. o The resources of Pioneer. At June 30, 2004, Pioneer managed over 62 investment companies and accounts with approximately $35 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, institutions, and other clients. As of June 30, 2004, assets under management of UniCredito Italiano S.p.A. were approximately $151 billion worldwide. o The track record of Pioneer in managing other investment companies with similar strategies. o Pioneer's willingness to proceed with the Reorganization and to limit expenses of the Portfolios as discussed above. o Pioneer's investment process, style and philosophy with respect to equity and fixed income investing. o Pioneer's willingness to act as investment adviser to each of the Funds. o Pioneer's investment process, style and philosophy with respect to equity and fixed income investing. o The expertise and experience of Kenneth Taubes as portfolio manager of several of Pioneer's bond funds and the head of fixed income investments at Pioneer. o Pioneer's willingness to act as investment adviser to each of the Funds. Safeco Advisory Agreement The following is a summary of the material terms of the Safeco Advisory Agreement. The Safeco Fund's Advisory Agreement with SAM terminated on August 2, 2004. Services. Under the terms of the Safeco Advisory Agreement, SAM managed the Funds' investments, subject to the supervision of the Board. At its expense, SAM provided office space and all necessary office facilities, equipment and personnel for managing the investments of the Funds. 127 Compensation. As compensation under the Safeco Advisory Agreement, each Safeco Fund paid SAM a monthly advisory fee at an annual rate as listed in the below table of the Fund's average daily net assets calculated each business day and paid monthly, as listed in the table below. In addition, SAM had contractually agreed to reimburse each Fund to the extent a Fund's total annual expenses during any of the Fund's fiscal years, exceed 0.40% (0.30% for Safeco Money Market Fund and Safeco Tax-Free Money Market Fund) of its average daily net asset value in such year.

Pioneer is an indirect, wholly owned subsidiary of UniCredito Italiano S.p.A., one of the largest banking groups in Italy. Pioneer is part of the global asset management group providing investment management and financial services to mutual funds, institutional and other clients. As of June 30, 2004, assets under management were approximately $150 billion worldwide, including over $35 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. 130 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 Pioneer Fund may 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. To the extent a Pioneer Fund invests in securities of non-U.S. issuers, 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 fund's 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. The Class A shares of the Pioneer Funds you receive in the Reorganizations will not be subject to any sales charge. Moreover, if you own shares in your own name as of the closing of the Reorganizations (i.e., not in the name of a broker or other intermediary) and maintain your account, you may purchase additional Class A shares of the corresponding Pioneer Fund through such account in the future or may exchange those shares for Class A shares of another Pioneer Fund without paying any sales charge.

Exchange Limitation. ou may only make up to four exchange redemptions of $25,000 or more per account per calendar year out of a 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 IRC. While financial intermediaries that maintain omnibus accounts that 134 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. Excessive Trading. The fund discourages excessive and short-term trading practices, such as market timing, that may disrupt portfolio management strategies and harm fund performance. 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 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. 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. We also limit the number of exchanges of $25,000 or more in any calendar year. 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. Frequently, fund shares are held through omnibus accounts maintained by financial intermediaries such as brokers and retirement plan administrators where the holdings of multiple shareholders, such as all the clients of a particular broker, are aggregated. Our ability to monitor trading practices by investors purchasing shares through omnibus accounts is limited and dependent upon the cooperation of the financial intermediary in observing the fund's policies. 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 Safeco 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. 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. 135 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. Distributions from each Pioneer Fund's net short-term capital gains and dividends from net investment income (other than exempt-interest dividends, as described below) are taxable as ordinary income. Since each Pioneer Fund's income is derived primarily from sources that do not pay "qualified dividend income," taxable dividends from each such fund generally will not qualify for taxation at the maximum 15% U.S. federal income tax rate available to individuals on qualified dividend income. For the Pioneer Tax Free Income Fund, Pioneer Municipal Bond Fund, Pioneer Tax Free Money Market Fund, and Pioneer California Tax Free Income Fund, dividends from each such fund's tax-exempt interest, called "exempt-interest dividends," are exempt from regular federal income tax. 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 (other than exempt-interest 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' Class A Rule 12b-1 Plans As described above, each Pioneer Fund has adopted a Rule 12b-1 plan for its Class A shares (the "Class A Plans" or the "Plans"). Because the 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. 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 6, 2003. 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. 136 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 Anderson LLP. The information for any semi-annual period has not been audited.

Georgeson Shareholder Communications Corporation, 17 State Street, New York, NY 10004 has been retained to provide proxy solicitation services to the Funds at a cost of approximately $30,000. Pioneer and Symetra will bear the cost of such solicitation. Revoking Proxies A Safeco 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 Safeco Fund's transfer agent, Safeco Services Corporation, at 4854 154th Place, N.E., Redmond, WA 98052, 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 Safeco 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 and Quorum Only shareholders of record on October 8, 2004 (the "record date") are entitled to notice of and to vote at the Meetings. As of the record date, the following number of shares of each Safeco Fund were outstanding. Shares Outstanding Safeco Fund (as of October 8, 2004) - ------------ ------------------------ Safeco California Tax-Free Income Fund ................ 7,787,094.598 Safeco High-Yield Bond Fund ........................... 6,824,746.096 Safeco Intermediate-Term Bond Fund .................... 1,108,689.158 Safeco Intermediate-Term Municipal Bond Fund .......... 1,047,405.901 Safeco Intermediate-Term U.S. Government Fund ......... 5,981,137.025 Safeco Money Market Fund .............................. 185,097,462.781 Safeco Municipal Bond Fund ............................ 37,390,239.812 Safeco Tax-Free Money Market Fund ..................... 52,150,057.170 Other Business Your Safeco Fund's Board of Trustees knows of no business to be presented for consideration at the Meetings other than Proposals 1(a)-(h) and 2(a)-(h). If other business is properly brought before a Meeting, proxies will be voted according to the best judgment of the persons named as proxies. Adjournments If, by the time scheduled for a 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 Safeco Fund will set a new record date), your Safeco Fund will give notice of the adjourned meeting to its shareholders. 142 Telephone Voting In addition to soliciting proxies by mail, by fax or in person, your Safeco Fund may also arrange to have votes recorded by telephone by officers and employees of your Safeco 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 votes would not be counted at the Meeting. Your Safeco 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. Internet Voting You will also have the opportunity to submit your voting instructions via the Internet by utilizing a program provided through a vendor. 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/Prospectus 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 [ ] us at [1-800 ] 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. Shareholders' Proposals Your Safeco 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 Safeco Fund to Safeco Mutual Funds, Attention Legal Department, 4854 154th Place, N.E., Redmond, WA 98052 within a reasonable time before any meeting. If the reorganization is completed, your Safeco Fund will not hold another shareholder meeting. Appraisal Rights If the Reorganization of your Safeco Fund is approved at the Meeting, shareholders of your Safeco 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 Safeco Funds, however, have the right to redeem their Fund shares until the closing date of the Reorganizations. After the Reorganization, shareholders of your Safeco Funds will hold shares of the Pioneer Funds which may also be redeemed at net asset value without being subject to deferred sales charges. 143 OWNERSHIP OF SHARES OF THE SAFECO FUNDS To the knowledge of your Safeco Fund, as of September 30, 2004, the following persons owned of record or beneficially 5% or more of the outstanding shares of each of the Safeco Funds. - ---------------------------------------------------------------------------------------------------------------- Safeco Fund Shareholder Name and Address Percentage Owned - ---------------------------------------------------------------------------------------------------------------- Safeco Intermediate-Term U.S. Charles Schwab & Co.

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 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. A-36 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 is not aware of any liabilities of any kind other than the Assumed Liabilities. 7. As of the Closing Date, the adjusted basis and the fair market value of the Acquired Assets will equal or exceed the Assumed Liabilities for purposes of Section 357(d) of the Code. 8. 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. All of the assets of the Acquired Fund held by Acquiring Fund as of the opening of business on August 2, 2004 (the date the Acquiring Fund Adviser became the investment adviser to Acquired Fund) were Acquired Fund's historic business assets within the meaning of Treasury Regulation Section 1.368-1(d)(3) (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. Rul. 73-54, 1973-1 C.B. 187. Acquired Fund will not pay any expenses incurred by its shareholders in connection with the transaction. 11. There is no, and never has been any, indebtedness between Acquiring Fund and Acquired Fund. 12. Acquired Fund has properly elected to be a regulated investment company under Subchapter M of the Code, has qualified for the special tax treatment afforded regulated investment companies under Subchapter M of the Code for each taxable year since inception, and qualifies for such treatment as of the time of the Closing. 13. Acquired Fund meets the requirements of an "investment company" in Section 368(a)(2)(F) of the Code. 14. Acquired Fund is not under the jurisdiction of a court in a Title 11 or similar case within the meaning of Section 368(a)(3)(A) of the Code. 15. Acquired Fund does not pay compensation to any shareholder-employee. 16. Immediately following the transaction, the Acquired Fund Shareholders will own all of the outstanding Acquiring Fund Shares and will own such shares solely by reason of their ownership of the Acquired Fund Shares immediately prior to the transaction. 17. Acquired Fund shareholders will not have dissenters' or appraisal rights in the transaction. 18. The transaction is being undertaken for valid and substantial business purposes, including facilitating Acquired Fund's becoming a member of the Pioneer family of mutual funds, which, in the long term, is intended to result in lower expenses and increased assets. 19. Acquired Fund has no outstanding warrants, options, convertible securities or any other type of right pursuant to which any person could acquire stock in Acquired Fund. * * * * * A-37 The undersigned officer of the Safeco Trust is authorized to make all of the representations set forth herein, and the undersigned is authorized to execute this certificate on behalf of Acquired Fund.

[SAFECO TRUST], on behalf of [SAFECO FUND] By: __________________________________ Name: ______________________________ Title: _____________________________ A-38 Exhibit B -- Form of Interim Advisory Agreement AGREEMENT dated as of August 2, 2004, between Pioneer Investment Management, Inc. ("Pioneer"), a Delaware corporation and a member of the UniCreditio Italiano Banking Group, Register of Banking Groups, and [SAFECO TRUST], a Delaware statutory trust (the "Trust"), on behalf of its series [SAFECO FUNDS] (the "Fund"). Whereas, Safeco Asset Management Company has acted as investment adviser to the Fund pursuant to an Investment Advisory Agreement dated (the "Prior Agreement"). Whereas, the Prior Agreement has been approved by the Board of Trustees of the Trust and the shareholders of the Fund. Whereas, the Prior Agreement is being terminated as a result of assignment. Whereas, the Board of Trustees has determined to appoint Pioneer as investment adviser to the Fund. Whereas, this Agreement is being entered into in reliance upon Rule 15a-4 under the Investment Company Act of 1940, as amended (the "Investment Company Act"). Now therefore the Trust and Pioneer agree as follow: Section 1. The Trust appoints Pioneer as investment adviser of the Funds for the period and on the terms set forth herein. Pioneer accepts such appointment. Section 2. Pioneer and the Trust, on behalf of the Fund, hereby agree that the provisions of the Prior Agreement (other than as to the term of the Prior Agreement, the identity of the Adviser and the use of the "Safeco" name) are incorporated herein by reference and made a part hereof as if references to the Adviser were to Pioneer. Without limiting the forgoing, Pioneer shall be entitled to the fee for its services provided for in the Prior Agreement from (but exclusive of) the date hereof until the termination of this Agreement, except as provided in Section 3 below. Section 3. In the event that this Agreement is not approved by a majority of the Trust's outstanding voting securities (as such term is used in the Investment Company Act), Pioneer shall be entitled to a fee equal to the cost to Pioneer of performing its services under this Agreement in lieu of the fee provided for in Section 2. For purposes of this Agreement, Pioneer's costs in providing the services under this Agreement shall be equal to the pro rata portion of Pioneer's expenses for the term of this Agreement attributable to its investment company advisory business, calculated as follows: Pioneer cost in providing investment advisory services to its investment companies of the same type (i.e., domestic equity, international, fixed income, money market) multiplied by a fraction the numerator of which shall be the average daily net assets of the Fund during the term of this Agreement and the denominator of which shall be the average month end net assets under Pioneer's management of all of its investment company clients. Section 4. The compensation earned by Pioneer under Section 2 of this Agreement shall be held in an interest bearing escrow account with the Fund's custodian. If a majority of the outstanding voting securities approves this Agreement prior to the end of its term, the amount in the escrow account (including any interest earned) shall be paid to Pioneer. If a majority of the outstanding voting securities do not approve this Agreement prior to the end of its term, Pioneer shall be entitled to be paid, out of the escrow account the lesser of (i) the amount in the escrow account (including any interest earned on that amount while in escrow) and (ii) the fee provided for in Section 3 (plus any interest on that amount while in escrow), with any remaining amount in the escrow account being returned to the Fund. Section 5. This Agreement shall become effective on August 2, 2004. Unless terminated as provided below, this Agreement shall remain in full force and effect until the earliest of (i) the closing of the reorganization of the Fund into [name of Pioneer Fund], (ii) approval of a Management Contract between the Fund and Pioneer and (iii) a date that is the later of 150 days after the date of the termination of the Prior Agreement or such later date as may be consistent with a rule or interpretive position (formal or informal) of the staff of the Securities and Exchange Commission. This Agreement may be terminated at any time without payment of penalty by vote of the Trustees of the Trust or by vote of a majority of the outstanding voting securities of the Fund. Pioneer may terminate this Agreement at any time without payment of any penalty on not less than 60 days written notice to the Fund. This Agreement shall automatically terminate upon its assignment as defined in the Investment Company Act. B-1 In witness whereof, the parties hereto have executed this Agreement as the 2nd day of August 2004. [SAFECO TRUST] -------------- --------------------------------------- By: ----------------------------------- Its: ---------------------------------- PIONEER INVESTMENT MANAGEMENT, INC. --------------------------------------- By: ----------------------------------- Its: ---------------------------------- B-2 Exhibit C -- 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 Exchange Act, 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. In circumstances where two or more broker-dealers offer comparable prices and executions, preference may be given to a broker-dealer which has sold shares of a fund as well as shares of other investment companies managed by Pioneer. This policy does not imply a commitment to execute all portfolio transactions through all broker-dealers that sell shares of the fund. None of the funds used any brokers affiliated with Pioneer during its most recently completed fiscal year in connection with its portfolio transactions.

Though it posted an overall negative return, the Safeco California Tax-Free Income Fund outperformed its benchmark index, the Lehman Brothers Long Municipal Bond Index, for the six-month period ending June 30, 2004. What factors impacted the Fund's performance? After a first quarter market rally, then sell-off, the first half ended with long-term bond yields rising about 50 basis points during the second quarter. The impetus for this change was more news demonstrating a stronger economy and an increasing threat of renewed inflation, which in turn could inspire the Federal Reserve to increase short-term yields at a faster pace than expected. With a longer average maturity than most of its peers, the Fund performed relatively poorly as bond prices declined sharply. What changes did you make to the Fund and why? Transactions for the period included two small sales of Los Angeles DWAP 4.25 '34 to retail customers at aggressive prices, and a tax swap. We sold San Jose Airport 5 '32 and bought Orange County Sanitary District 5 '33 in order to realize a small loss, which can be used to offset gains for tax purposes.

Year-to-date performance of the fund has exceeded both the benchmark, the Merrill Lynch High-Yield Master II Index, and the high-yield peer median. What Factors impacted the Fund's performance? Our credit selection and overweight in CCC-rated bonds largely accounted for the Fund's good relative performance during the first half of the year. We likely removed the overweight in CCC too soon and missed the rally during the last part of the second quarter. Nine of our holdings announced refinancing and/or tenders, which provided a positive "pop" to returns reflecting our credit picks. Two negative credit events were Pegasus Satellite, which deteriorated quickly, and in MCI stock we received in exchange for WorldCom bonds. The latter declined as short-term bankruptcy investors sold the stock and long-term holders have been slow to add positions in a difficult sector. What changes did you make to the Fund and why? The number of overall holdings has been reduced to a more manageable level, between 100 and 120 positions. Diversification remained strong as we trimmed larger holdings and selectively added to several top-25 positions. No bond exceeds 2% of assets and we continue to reduce the percentage of our asset level in the top 10. We continue to overweight industrial and cyclical sectors, underweight defensive sectors and BB-rated credits, and maintain a shorter duration versus our benchmark. Our overall yield-to-maturity and coupon return to shareholders are close to or exceed the benchmark. We achieve this by holding high coupon "cushion" bonds likely to be called in the near term. High-yield bonds, especially those rated BB, will be hurt as Treasury rates rise at this point in the cycle. The effort to counteract rising interest rates is three-fold. First, underweighting BB-rated issues and slightly shorten the duration. Second, adding adjustable rate bonds to offset the Federal Reserve rate increases. Finally, identifying near-term credit upgrade candidates not fully reflected in the market. The latter is admittedly difficult in this fairly valued market.

The Safeco Intermediate-Term Bond Fund slightly outperformed its benchmark index, the Lehman Aggregate Bond Index, for the six-month period ending June 30, 2004. What factors impacted the Fund's performance? While interest rates declined in the first quarter, they rose sharply during the second. The Fund benefited its relatively short duration and 10.5% underweight holdings in Treasury securities, which underperformed the most of any sector. However, the fund was hurt by its 6.4% underweight in mortgage securities, the best-performing sector of the second quarter. The Federal Reserve increased the Fed Funds rate to 1.25% from 1.00% on June 30; the first rate change in a year. We believe that the Fed will continue to raise rates through year-end and into 2005, most likely in 25 basis points steps. The Fed appears to be focused on inflation and employment so we expect the bond market will be very sensitive to both data releases. Any unanticipated strength or weakness in either could cause yields to gyrate in either direction although we believe the overall trend should be up. In this scenario the Fund, with its shorter duration versus the peer group, should perform well. What changes did you make to the Fund and why? Early in the year we restructured the maturity profile of our Treasury exposure, laddering holdings across the entire yield curve and selecting specific positions with the highest yield per unit of duration risk. We also increased our exposure to callable agency securities to increase the portfolio's yield; this helped cushion the blow from the second quarter's rise in rates. Second quarter activity was aimed at maintaining our slightly short duration and maintaining the mortgage-backed securities (MBS) allocation. The Fund used the cash from mortgage paydowns to purchase mortgage pass-through to maintain the allocation of MBS helping to maintain the portfolio's yield. The Fund reduced its exposure in the corporate bond sector modestly, swapping a 30-year corporate bond for a similar maturity Treasury bond. The Fund also tendered some 10-year corporate bonds and invested the proceeds in similar maturity Corporates.

The Safeco Intermediate-Term Municipal Bond Fund matched its benchmark index, the Lehman Brothers 7-Year Municipal Bond Index, for the six-month period ending June 30, 2004. What factors impacted the Fund's performance? After gaining fairly steadily since last summer, bond prices moved down during most of the first quarter, recovering somewhat in late May and June. We underperformed during the period. The steep decline (approximately 100 basis point in a two-month period beginning in March and ending in May) hurt us, and the period of increased stability at the end of the quarter was not long enough for us to recover from the hit. What changes did you make to the Fund and why? We did not make any changes in the basic structure of the fund. We did just one trade during each quarter. During the first quarter, we added to our position in Chicago, IL Tax Increment 5%. During the second quarter, we purchased Columbus, Ohio, general obligation bonds. These are very high credit-quality bonds from a state where a significant premium is usually paid by investors in order to gain the state tax exemption. The bonds, however, were sold at close to general market values. We believe that at some point in the future, the spread will widen out and their value will increase relative to other bonds.

The Safeco Intermediate-Term U.S. Government Fund outperformed its benchmark index, the Lehman Intermediate Government Index, for the six-month period ending June 30, 2004. What factors impacted the Fund's performance? Rising interest rates marked a performance shift between the first and second quarters. While rates fell in the first quarter, favoring longer duration securities, rates began an upward climb in the second. The Fund's shorter duration, along with its exposure to mortgage-backed securities (MBS), allowed it to benefit from this rising interest-rate environment and contributed to improved performance relative to the benchmark for the first six months of the year. What changes did you make to the Fund and why? Trading activity for the first six months was aimed at modestly lengthening the Fund's duration, increasing yield, and maintaining the MBS allocation. During the first half of the year, we sold a four-plus year Treasury to buy a longer duration Treasury security (2023 maturity) to increase the Fund's exposure to the long end of the yield curve and lengthen its duration. Some of the proceeds were also used to buy 30-year 5.5% FNMA pass-throughs to maintain the allocation of MBS slightly above 40%. The Fund used the cash from mortgage pay downs to purchase a 30-year 5.0% FNMA pass-through to maintain the allocation of MBS slightly above 40%. The Fund also sold an eight-year Treasury and bought a 10-year Federal Home Loan Bank (FHLB) bond. The FHLB bond yielded almost 1.5% more than the Treasury. This added both yield and duration to the portfolio.

Current Yield (30-day) ............ 3.16% Weighted Average Maturity ......... 4.6 years D-10 Report From the Fund Managers Safeco Money Market Fund As of June 30, 2004 How did the Fund Perform? The Fund had returns for the six-month period ending June 30, 2004 above the average of other taxable money market funds. However, the 12-month return on the Fund was lower than the 3.2% year-over-year increase in the Consumer Price Index (CPI) as of the end of June 2004. What factors impacted the Fund's performance? After a full year of the Federal Funds target rate of 1.00%, the Federal Reserve's Open Market Committee (FOMC) finally raised the rate to 1.25% on June 30. The Fed Funds futures market anticipates a 0.25% rise in the rate at each of the four remaining FOMC meetings in 2004 and even higher rates in 2005. The main reason the Fund outperformed the Lipper benchmark was the large holdings (33%) of 7-day reset floating rate notes that reset off of the 1-month London inter-bank offer rate (LIBOR). LIBOR-based securities currently offer higher rates than other available money market securities, and the frequent rate reset of the notes captures higher rates more quickly in a rapidly rising rate environment. Also contributing to the superior returns were the Fund's holdings of longer-term corporate bonds purchased at relatively high yields on a steep money market yield curve. What changes did you make to the Fund and why? We increased the allocation of floating rate notes. This has become our asset class of choice because the spread is much higher than commercial paper. We continued to reduce our holdings of Commercial paper (to 31% of Fund) relative to our peers (49% according to iMoneyNet). Commercial paper remains one of the lowest-yielding assets in the prime money markets. After rates had risen significantly, we made a purchase of a Federal Home Loan Bank (FHLB) thirteen-month maturity bond which is callable every three months and some purchases of one-year bank and broker paper.

Though it had negative overall performance, the Safeco Municipal Bond Fund outperformed its benchmark Index, the Lehman Long Municipal Bond Index, for the six-month period ending June 30, 2004. What factors impacted the Fund's performance? After a typical first quarter, long-term bond yields rose about 50 basis points during the second quarter. This was due to more news demonstrating a stronger economy and an increasing threat of renewed inflation, both of which could inspire the Federal Reserve to increase short-term yields at a faster pace than expected. With a longer average maturity than most of its peers, the Fund performed relatively poorly during the first half, as bond prices declined sharply. What changes did you make to the Fund and why? Three new issues were purchased during the first half of 2004. All were rated A by Standard & Poor's, and offered significant additional yield to the benchmark AAA scale. In the first quarter, we purchased $4 million of Dorchester County School District 5.25 12/1/29 to yield 4.90%. These A-rated bonds provided 55 basis points more yield than AAA bonds, a very attractive spread. In the second quarter, Empire State Development Authority 5.125 7/1/21 came to market at a yield of 4.70%, 49 basis points more than AAA bonds. Puerto Rico Highway 5.125% 7/1/43 bonds were offered at a yield of 5.20%, which was an additional 42 basis points over AAA-rated bonds. We also swapped out of several bonds priced near par into deeper discounts. This move afforded a greater total return in the event of a market turnaround without adding significant downside potential.

The Fund had returns above the average of other tax-free money market funds for the six-month period ending June 30, 2004. What factors impacted the fund's performance? Although in absolute numbers the return is small, the fund has continued to fare well compared to its peers. The structure of the portfolio serves us well. As of June 30, 66% of the fund was invested in variable rate demand option (VRDO) bonds which can be tendered on a daily or weekly basis, and 34% in six-month and one-year put bonds. The heavy weighting in VRDOs gives us liquidity and flexibility, along with a competitive yield. The longer put bonds let us lock in some higher rates on a smaller portion of the fund. What changes did you make to the fund and why? We have not made any significant changes to the fund. The barbell strategy outlined above -- with a heavy concentration in VRDOs, a smaller concentration in put bonds, and not much in between -- has worked for us consistently.

D-17 Portfolio Management's Discussion of Fund Performance (as of April 30, 2004) High-yield bonds continued a string of solid performance during the six months ended April 30, 2004. Here, Fund manager Margaret Patel explains the rebound in the high-yield market and the factors that influenced the Fund's performance. Q: How did the Fund perform? A: During the six months ended April 30, 2004, the Fund had a total return based on net asset value of 4.43% for the Fund's Class A shares, 4.01% for Class B shares, 4.07% for Class C shares, 4.65% for Class R shares, and 4.61% for Class Y shares. To compare, the Merrill Lynch High Yield Master II Index returned 5.35%. Q: What was the environment like for the high-yield market during the past six months? A: The yield spread, or differential, between high-yield bonds and comparable Treasuries narrowed, highlighting the solid performance of the high-yield market. This yield spread narrowing reflected a brighter outlook for the economy and the declining default rate among high-yield bonds. The Federal Reserve Board aided the positive backdrop by providing ample liquidity to the markets in the form of historically low interest rates. A modest level of new supply also benefited the high-yield market, helping to buoy price appreciation among outstanding bonds as demand for the asset class remained high. With interest rates so low, investors looked to the high-yield market for more attractive yields at a time when the strengthening economy made them more comfortable venturing there. Q: Why did the Fund modestly under perform the Merrill Lynch High Yield Master II Index? A: Much of the stronger relative performance offered by the index came from the out-performance of low-quality bonds rated CCC or lower. We had very little exposure to the lower-rated segments of the market, instead focusing more of the Fund on those securities rated BB or BBB. These higher-rated bonds tend to be more sensitive to changes in interest rates and, thus, suffered on a relative basis as yields on comparable intermediate Treasury securities rose during the period. However, we felt that the better-quality issues should offer more favorable performance at this juncture in the market cycle. In addition, more speculative industries, such as airlines, telecommunications and lower-tier electric utilities, were among the best performers during the period. We avoided these industries, feeling that they were too risky and did not meet our investment criteria, particularly because we believed that they were less likely to benefit from an economic upturn than the alternatives we found in other sectors. Q: What was your strategy during the period? A: We decreased the proportion of the Fund devoted to convertible securities from about 56% of the portfolio to just over 49%, and increased its stake in standard corporate high-yield bonds from about 43% to about 50%. We made this move because many convertible securities became fully valued, having benefited from low interest rates and the substantial increase in the underlying value of the issuing companies' stocks. We invested the proceeds from these sales in the areas we judged to be most attractively valued within the high-yield market. We also reduced the Fund's allocations to the technology and health care sectors, including investments in pharmaceutical and biotechnology companies. These securities offered substantial out-performance, reaching fully valued levels. In addition, some technology companies called a number of convertible bonds. That is, the issuers decided to redeem the bonds by paying them off, requiring us to surrender the securities. The assets we gained from our sales and redemptions were used to increase the Fund's focus on cyclical companies that we felt were best positioned to benefit from an improving economy. Overall, these firms should benefit from better supply and demand fundamentals, as well as being helped modestly by the cheapening U.S. dollar. Q: Does your recent strategy mean you're gravitating away from a focus on convertible securities? A: No, it does not. Convertible securities remain a viable investment alternative for the Fund. When we use them, we look for those convertibles that are selling at discounted prices and offering high yields. We invest in companies within industries where generic high yield bonds are not in strong supply, especially smaller companies within rapidly growing industries. Discounted convertible securities can offer appealing prospects because their prices can appreciate more than regular bonds if the underlying value of the company's stock rises. Also, holders of convertible bonds can earn attractive yields similar to those offered within the high-yield market. D-18 Q: Which investments proved to be some of the top performers during the fiscal year? Which disappointed? A: Tesoro Petroleum was one of the top performers during the period. This West Coast refining company profited from improved refining margins. Wabash National, which manufactures truck trailers, benefited from improved demand and better pricing. The health care sector offered particularly strong performance for the Fund, with Protein Design Labs, Enzon Pharmaceuticals, Human Genome, Ligand Pharmaceuticals and Sepracor all demonstrating success with drug discovery or bringing new pharmaceutical products forward for approval. In technology, Flir Systems, Xerox, Conexant Systems, Lam Research, Brooks Automation and Triquint Semiconductors all posted improved operating results driven by firmer pricing and a better outlook for the industry. Disappointments included basic materials holdings Freeport Mac MoRan and Inco. These holdings declined due to concerns about softening demand for their products from China. In addition, publisher Houghton Mifflin fell due to disappointing earnings results and projections. Q: What is your outlook? A: We remain optimistic because we expect corporate earnings growth rates to continue to come in above long-term averages as the U.S. economy expands. We also anticipate further declines in the default rate to well below its historical average of 3%, due to solid economic growth and substantial liquidity in the marketplace. Although we expect yields on Treasuries to rise, we feel that the extra income offered by high-yield bonds should outweigh the price erosion that accompanies such an increase. The outlook for the equity market is very bright, reflecting positive earnings forecasts. As a result, convertible securities could appreciate in price should the underlying stocks move upward in response to better earnings reports.

D-20 Portfolio Management's Discussion of Fund Performance (as of June 30, 2004) As market interest rates spiked up in the final half of the 12-month period ending June 30, 2004, high-yield corporate bonds and mortgage-backed securities provided the best defensive protection, as conditions changed in the U.S. fixed-income market. In the following discussion, Kenneth J. Taubes discusses the factors that influenced Pioneer Bond Fund's performance during the 12 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 the 12 months ended June 30, 2004? A: In a challenging period for fixed-income investing, Pioneer Bond Fund outdistanced both market benchmarks and competitive peer group averages. For the 12 months, the Fund's Class A shares had a total return of 2.98%, while Class B and Class C shares returned 2.04% and 2.11%, respectively, all at net asset value. During the same 12 months, the Lehman Aggregate Bond Index had a return of 0.32%, while the average return of funds in Lipper's A-Rated Corporate Debt category was 0.04%. The Fund also continued to deliver a competitive yield. The standardized 30-day SEC yield on Class A shares on June 30, for example, was 4.30%. Q: What were the factors that affected performance? A: The Fund's performance was helped both by asset allocation and good security selection. We had the largest overweight positions in the two asset classes with the best performance during the 12 months: high-yield corporate bonds and mortgage-backed securities. Throughout the year, we kept the Fund's high-yield exposure close to the 20% limit of our policy. That strategy helped substantially as the high-yield market, as measured by the Merrill Lynch High Yield Master II Index, returned 10.30% for the 12 months. We also had more than 40% of assets invested in mortgage securities during a period in which mortgages were the best performing part of the investment-grade fixed-income market. As a result, typically 60% to 65% of Fund assets were invested in the two best performing parts of the bond market. Both high-yield bonds and mortgage-backed securities tend to be more resistant to the effects of price losses from increasing interest-rates than other bonds because of their yield advantages. The performance of mortgage-backed securities is also helped by the tendency of mortgage prepayment risk to decline as interest rates rise. We held our allocation to Treasury securities, the worst performing part of the bond market, to less than 10% of assets during the period, and focused our Treasury exposure on inflation-protected Treasuries, which outperformed standard Treasury securities. Treasuries were the worst performing part of the fixed-income market. During the 12-month period, the prices of 10-year Treasuries declined by 7.5%. Q: What types of security selections had the greatest influence on performance? A: Several high-yield corporate bonds made significant contributions to performance. Bonds issued by Corning, which restructured its business to focus on the production of the material used for flat screen monitors, did very well, as did securities of retailer J.C. Penney, which improved its credit position through restructuring and the sale of its pharmacy chain division. Bonds issued by hotel chains also did well as the economy improved and business travel increased. Among the top performers in the portfolio were bonds issued by the Hilton, Starwood and John Q. Hammond hotel chains. The securities of insurance company Allmerica Financial also appreciated in price during the period as a result of that company's positive restructuring efforts. Q: How would you describe the Fund's overall positioning? A: We kept the Fund positioned to benefit from the improving economy, which helps support the corporate bond market, while guarding against the threat of rising interest rates. At the end of the fiscal year, on June 30, mortgage securities accounted for 44.9% of Fund assets, while corporate high-yield bonds made up 18.5% of the portfolio. About 30.3% of assets were in investment-grade corporates, and just 1.4% of assets were invested in Treasuries. Because rising interest rates tend to undermine bond prices, we shortened the Fund's duration to lower its sensitivity to changes in interest rates. Duration, a measure of interest-rate sensitivity, declined during the period from 4.7 years at the start of the fiscal year to 4.3 years on June 30, 2004. Average credit quality on June 30, 2004 was A. D-21 Q: What is your outlook for the bond market? A: We believe the economy is healthy and should continue to grow. Short-term rates currently are below the rate of inflation and should be expected to continue to rise in the coming months. The Federal Reserve began to raise the important Fed Funds rate, the most influential short-term rate, on June 30, and we expect further tightening by the Fed in the months ahead. We believe market rates on longer-term bonds, which rose in the months leading up to the June 30 announcement, probably are priced appropriately for current conditions, but pressure on shorter-term and intermediate-term interest rates should continue for several more quarters. The outlook for corporate securities appears good, however, as more companies gain additional pricing power, which should help them strengthen their balance sheets. We recently have initiated some positions in the steel industry, for example, an area we have generally avoided in the past. In this environment, we anticipate maintaining a focus on corporate bonds and mortgage-backed securities and expect to maintain the Fund's position to mute the impact of rising interest rates of short- and intermediate-term securities by keeping duration relatively short.

The Lehman Brothers Municipal Bond Index is a widely recognized, unmanaged measure of approximately 15,000 municipal bonds. Bonds in the Index have a minimum credit rating of BBB, were part of at least a $50 million issuance made within the past five years and have a maturity of at least two years. Index returns are calculated monthly, assume reinvestment of dividends and, unlike Fund returns, do not reflect any fees, expenses or sales charges. You cannot invest directly in the Index. A portion of the Fund's income may be subject to the Alternative Minimum Tax (AMT) or state and local taxes. D-23 Portfolio Management's Discussion of Fund Performance (as of June 30, 2004) While yields and prices on municipal bonds fluctuated widely during the first half of 2004, on June 30, 2004, yields were higher and prices were lower than they had been six months before. In this environment, the Fund distributed a relatively high level of tax-free income to shareholders. 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 Safeco Fund. Q: How did the Fund perform? A: For the six-month period ended June 30, 2004, Pioneer Tax Free Income Fund's Class A shares produced a -1.65% return; Class B shares returned -1.96%; and Class C shares -1.96%, all at net asset value. The Fund's benchmark, the Lehman Brothers Municipal Bond Index returned -0.68%, and the average return of the 302 funds in the Lipper General Municipal Debt Funds Category was -0.99%. Lipper is an independent monitor of mutual fund performance. While we shortened the duration of the Fund, we did not reduce it so much as to sacrifice yield. The funds in the Lipper category have a much shorter duration than the Fund; and that difference in duration accounted for the underperformance relative to Lipper. (Duration measures a bond's sensitivity to interest rate changes. In a rising interest rate environment, a shorter duration is usually advantageous because it mitigates price erosion.) The Fund's Class A shares generated a 30-day SEC tax-free yield of 5.23% as of June 30, 2004. That translates into a taxable equivalent yield of 8.05%, based on the maximum federal income-tax rate of 35%. Q: Why did the Fund under perform the benchmark? A: The relative underperformance of the Fund's tobacco bonds, which accounted for about 9% of net assets, was the primary detractor from performance versus the Lehman Brothers Municipal Bond Index. While tobacco bonds provided a very high level of income, their prices declined because certain court rulings regarding tobacco companies were interpreted negatively by the investment community. The Fund's allocation to transportation bonds, which was about 4% of net assets, also detracted from performance. During the period, Delta Airlines raised the possibility of filing for bankruptcy. While we did not hold Delta bonds, nearly all airline bonds were negatively affected by the company's announcement. The Fund's 34.6% allocation to AAA-rated bonds also held back total return. Q: What was the investment environment like during the period? A: There were two distinct environments during the period. For the first quarter of 2004, interest rates continued to decline, because investors were not sure about the sustainability of the economic recovery. As we moved into the second quarter, however, data began to indicate that the economy was on a relatively strong recovery course and that hundreds of thousands of new jobs had been created. The strong jobs numbers sparked concerns about accelerating inflation and higher interest rates. Against this backdrop, yields on both taxable and tax-free bonds rose sharply. While yields moved higher across all maturities, those on short-term bonds went up the most. Q: What contributed to performance? A: The declining interest rates in the first quarter of 2004 were a substantial help to performance. Also, the higher-yielding -- or below investment-grade -- bonds in the portfolio aided results. Q: What were the principal strategies used in managing the Fund? A: In keeping with the Fund's guidelines, we maintained our strategy of keeping up to 10% of net assets in below investment-grade securities, which enhanced the Fund's income and performance. The rest of the portfolio was invested in investment-grade bonds. We focused on economically sensitive market sectors, areas in which the underlying credit quality of fixed-income securities tends to improve during periods of economic recovery. These sectors included the hospital/health care, transportation, and power/energy parts of the market. As mentioned above, to moderate the Fund's price decline as interest rates rose, we shortened duration. D-24 Q: What is your outlook? A: We believe the economy will continue on a positive growth path. The Fed boosted rates by 0.25% on June 30, and we expect the central bank to continue making modest rate hikes over the second half of 2004. The Fed's actions could push short-term yields higher. We believe the possibility of higher interest rates will increase the level of income to the Fund. At the same time, the portfolio's shorter duration will help guard against the possibility of price loss as interest rates begin to rise. Another factor that could benefit the Fund is the significant decline in the issuance of new bonds. In 2003, low interest rates made it attractive for municipalities to borrow money in record numbers. In 2004, new issuance could be down as much as 20%. While supply may be down, demand remains constant. This supply/demand dynamic can raise the value of certain municipal bonds.

The Lehman Brothers Government Bond Index is an unmanaged measure of the performance of U.S. Treasury debt, all publicly issued debt of U.S. government agencies and quasi-federal corporations, and corporate debt guaranteed by the U.S. government. The Lehman Brothers Fixed-Rate Mortgage-Backed Securities Index is an unmanaged index including 15- and 30-year fixed rate securities backed by mortgage pools of the Government National Mortgage Association (GNMA), Federal Home Loan Mortgage Corporation (FHLMC) and Federal National Mortgage Association (FNMA). Index returns assume reinvestment of dividends and, unlike Trust returns, do not reflect any fees, expenses or sales charges. D-26 You cannot invest directly in the Indexes. Portfolio Management's Discussion of Fund Performance (as of June 30, 2004) In an improving economy, uncertainty about rising interest rates dominated market sentiment. As a result, the yields on fixed-income securities declined and then rose, as investors tried to determine when the Federal Reserve would raise interest rates and by how much. In this volatile environment, Pioneer America Income Trust delivered a relatively high level of income to shareholders. 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 six months. Q: How did the Trust perform during the six-month period ended June 30, 2004? A: For the six-month period ended June 30, 2004, Class A shares of Pioneer America Income Trust produced a total return of -0.14% at net asset value. The Trust performed in line with the Lehman Brothers Government Bond Index, which returned -0.13% for the same period. It under performed the Lehman Brothers Fixed-Rate Mortgage-Backed Index, which returned 0.77%. We attribute the Fund's underperformance relative to the Lehman Brothers Fixed-Rate Mortgage-Backed Index to the fact that the index has significant exposure to securities issued by the Federal Home Loan Mortgage Corporation (Freddie Mac) and the Federal National Mortgage Association (Fannie Mae), which outperformed. Because these securities do not have the backing of the full faith and credit of the U.S. Government, we do not invest in them. The Trust outperformed the -0.32% return generated by the General U.S. Government Funds Category of Lipper, Inc., an independent monitor of mutual fund performance. At the end of the period, the 30-day SEC yield for Class A shares was 4.26%. Q: What was the investment environment like during the period? A: For the first three months of 2004, concerns about geopolitical issues and the "jobless" economic recovery kept interest rates at 45-year lows. When we moved into the second calendar quarter of 2004, however, the employment picture changed dramatically. Several hundred thousand jobs were added to the economy in April and May, leading to concerns about accelerating inflation, the pace of Federal Reserve tightening and higher interest rates. In this environment, market interest rates rose, causing the yield curve to flatten. (The yield curve shows the relationship between bond yields and maturity lengths.) Normally, the yield curve is positively sloped, with yields on long-term bonds exceeding those on short-term bonds. The yield curve flattens when yields on short term bonds rise more than those on long-term bonds, as was the case during the period. As interest rates rose, bond yields went up and prices declined. Q: What investment strategies contributed to performance? A: Nearly 75% of net assets were invested in mortgage-backed 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 GNMA securities outperformed Treasuries, the Trust's focus on mortgages relative to the benchmark was the biggest aid to total return. In the volatile interest-rate environment, we were concerned about the prepayment risk that is associated with mortgage-backed securities. 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 selected mortgages that had lower weighted average coupon (stated rate of interest) rates, which we believe are less likely to be prepaid. D-27 Q: What investment strategies detracted from performance? A: Nearly 25% of the portfolio was invested in Treasury securities with predominantly short- and intermediate-term maturities. As yields on securities in these maturity ranges moved higher, their prices declined. As a result, the Trust's exposure to bonds in the middle of the yield curve held back results. Q: What is your outlook over the next several months? A: We believe the economy is on a sustained path for improvement and are concerned that the seeds for higher inflation are being planted. The Federal Reserve raised interest rates by 0.25% on June 30 and is likely to continue doing so at a measured pace over the next two years. As interest rates move higher, we will consider using a barbell strategy in managing the Treasury portion of the Trust -- that is, we may sell some of our intermediate-term holdings and add securities in the one-to-two-year range and in the 20 plus-year range. With this approach, the Trust should benefit from the higher yields that long-term bonds provide and from the relative price stability of short-term securities. We will also seek mortgage-backed securities that are selling at a discount and that can provide the Trust with relatively high yields as well as the potential for price appreciation.

Performance data shown represents past performance. Past performance does not guarantee future results. Investment returns will fluctuate, and there can be no guarantee the Fund will be able to maintain a stable net asset value of $1.00 per share. An investment in the Fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. 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. Pioneer has agreed to limit the fund's expenses for any class of shares 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 of 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. Performance does not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption of Fund shares. D-29 Portfolio Management's Discussion of Fund Performance (as of June 30, 2004) Short-term interest rates remained at 46-year lows during the first half of 2004, although the U.S. Federal Reserve Board finally signaled a shift in its accommodative monetary policy on June 30 when it raised the key Fed Funds Rate from 1.00% to 1.25%. Throughout the six months, Pioneer Cash Reserves Fund maintained a $1 share price and provided modest current income consistent with the low 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 leading 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 six months ended June 30, 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 the first half of 2004? A: For the six months ended June 30, 2004, Pioneer Cash Reserves Fund Class A shares had a total return of 0.09%, while Class B, Class C and Class R shares each had returns of 0.03%. All returns were at net asset value. For the same six months, the average return in Lipper's Money Market Fund category was 0.17%. On June 30, 2004, the Fund's seven-day effective yield for Class A shares was 0.35%. Q: What factors affected Fund performance? A: Short-term interest rates remained at historically low levels over the six months. It was a period, however, in which evidence steadily accumulated that the U.S. economy was recovering briskly. Growth Domestic Product (GDP), for example, grew by an annual rate of 3.9% for the first three months. The nation's industrial production increased by 5.6% since June 30, 2004, and the economy added 1.4 million new jobs during the same 12 months. Evidence of the economy's vibrancy became more persuasive during the six months, especially after the Department of Labor released an unexpectedly strong new-jobs report for March. Market interest rates began rising and expectations grew that the Federal Reserve Board finally would shift from its accommodative monetary policy and begin raising short-term interest rates. The Fed confirmed those expectations on the final day of the six month period when it raised the influential Fed Funds Rate by one quarter of one percent and signaled that it was likely to raise the rate further in subsequent months to head-off inflationary threats. Q: Given this environment, what strategies did you pursue? A: We held to our quality orientation in managing the Fund, but gradually lowered the effective duration from 61 days on December 31, 2003, to 51 days by June 30, 2004. We did this as we saw that the Federal Reserve was likely to begin to raise rates. A shorter duration portfolio gives the Fund more flexibility in investing in new, higher-yielding securities as rates start to rise. Q: What is your investment outlook? A: We anticipate that while the Federal Reserve will continue to stimulate continued economic growth, it is likely to raise short term rates further for the remainder of 2004 and at least the beginning of 2005. Given this outlook, we expect to keep effective duration relatively short to give us the flexibility to capture additional yield as rates rise. However, we also expect to take a more bar belled approach, with concentrations both in very short, one-to two-month securities and in one-year maturities, where higher yields are available. We also intend to consider opportunities to invest in floating-rate notes, where we can obtain higher yields without taking more risk.

General The accompanying pro forma combined financial statements are presented to show the effect of the proposed acquisition (the "acquisition") of Safeco Intermediate-Term U.S. Government Fund by Pioneer America Income Trust. Under the terms of an Agreement and Plan of Reorganization between the Funds, the combination of Pioneer America Income Trust and Safeco Intermediate-Term U.S. Government 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 Safeco Intermediate-Term U.S. Government Fund in exchange for a new "Investor Class" of shares of Pioneer America Income Trust at net asset value, which will be established upon consummation of the merger. The accompanying schedules of investments, statements of assets and liabilities and the related statements of operations of Pioneer America Income Trust and Safeco Intermediate-Term U.S. Government Fund have been combined as of and for their most recent 12 months ended June 30, 2004. Adjustments have been made to expenses for duplicate services that would not have been incurred if the merger took place on July 1, 2003. Following the acquisition, Pioneer America Income 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 Pioneer America Income Trust and Safeco Intermediate-Term U.S. Government Fund included in their respective semiannual reports to shareowners dated June 30, 2004. 2. Organization and Significant Accounting Policies 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. After the merger, the Trust will consist of five classes of shares - Class A, Class B, Class C, Class R and Investor Class shares. Class R shares were first publicly offered on April 1, 2003. Investor Class shares are being offered as part of the acquisition. Shares of Class A, Class B, Class C, Class R and Investor Class each represent an interest in the same portfolio of investments of the Trust and have equal rights to voting, redemptions, dividends and liquidation, 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 Investor Class shares. Each Fund's management has prepared their respective financial information using estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the pro forma financial statements, and the reported amounts of income, expenses and gains and losses on investments during the reporting periods. Actual results could differ from those estimates. -10- The following is a summary of significant accounting policies consistently followed by the Trust, which are in conformity with those generally accepted in the investment company industry: A. Security Valuation Security transactions are recorded as of trade date. Securities are valued at prices supplied by independent pricing services, which consider such factors as Treasury spreads, yields, maturities and ratings. Valuations may be supplemented by dealers and other sources, as required. Securities for which there are no other readily available valuation method are valued at their fair values as determined by, or under the direction of the Fund's Board of Trustees. At June 30, 2004, there were no securities fair valued. 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 pay downs. 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. Gains and losses on sales of investments are calculated on the identified cost method for both financial reporting and federal income tax purposes. B. Federal Income Taxes Each fund has previously elected to be taxed as a "regulated investment company" under the Internal Revenue Code. After the acquisition, it will be 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. At December 31, 2003, the combined capital loss carryforward of $8,538,000 includes a net capital loss carryforward of $1,398,000 from the merger with Safeco Intermediate-term U.S. Government Fund, the full use of which may be limited. C. Fund Shares The Trust records sales and repurchases of its shares as of trade date. Pioneer Funds Distributor, Inc. (PFD), the principal underwriter for the Trust and a wholly owned indirect subsidiary of UniCredito Italiano S.p.A. (UniCredito Italiano), earned $40,046 in underwriting commissions on the sale of Trust shares for the 12 months ended June 30, 2004. D. Class Allocations Distribution fees are calculated based on the average daily net asset value attributable to Class A, Class B, Class C, Class R, and Investor Class shares of the Trust, respectively. Shareowners of each class share all expenses and fees paid to the transfer agent, Pioneer Investment Management Shareholder Services, Inc. (PIMSS), for its services, which are allocated based on the number of accounts in each class and the ratable allocation of related out-of-pocket expenses (see Note 5). Income, common expenses and realized and unrealized gains and losses are calculated at the Trust level and allocated daily to each class of shares based on the respective percentage of adjusted net assets at the beginning of the day. The Trust declares as daily dividends substantially all of its net investment income. All dividends are paid on a monthly basis. Short-term capital gain distributions, if any, may be declared with the daily dividends. Distributions to shareowners are recorded as of the ex-dividend date. Distributions paid by the Trust with respect to each class of shares are calculated in the same manner, at the same time, and in the same amount, except that Class A, Class B, Class C, Class R, and Investor Class shares can bear different transfer agent and distribution fees. -11- E. Repurchase Agreements With respect to repurchase agreements entered into by the Trust, the value of the underlying securities (collateral), including accrued interest received from counter parties, is required to be at least equal to or in excess of the value of the repurchase agreement at the time of purchase. The collateral for all repurchase agreements is held in safekeeping in the customer-only account of the Trust's custodian, or sub custodians. The Trust's investment adviser, Pioneer Investment Management, Inc. (PIM) is responsible for determining that the value of the collateral remains at least equal to the repurchase price. 3. Capital Shares The pro forma net asset value per share assumes the issuance of shares of the Trust that would have been issued at June 30, 2004, in connection with the proposed acquisition. The number of the shares assumed to be issued is equal to the net asset value of Safeco Intermediate-Term U.S. Government Fund, as of June 30, 2004, divided by the net asset value per share of the Investor Class shares of the Trust as of June 30, 2004. The pro forma number of shares outstanding (in thousands), by class, for the combined fund consist of the following at June 30, 2004: Shares of Additional Shares Total Outstanding The Trust Assumed Issued Shares Class of Shares Pre-Combination In Reorganization Post-Combination - --------------- --------------- ----------------- ---------------- Class A 13,322 13,322 Class B 4,586 4,586 Class C 3,148 3,148 Class R 49 49 Investor Class - 6,866 6,866 4. Management Agreement PIM manages the Trust's portfolio and is a wholly owned indirect subsidiary of UniCredito Italiano. Management fees are calculated daily at the annual rate of 0.50% of the Trust's average daily net assets. PIM discontinued the Fund's expense limitation on May 1, 2003. Prior to May 1, 2003, PIM had agreed not to impose a portion of its management fee and to assume other operating expenses of the Trust to the extent necessary to limit Class A expenses to 1.00% of the average daily net assets attributable to Class A shares; the portion of the Trust-wide expenses attributable to Class B, Class C and Class R shares were reduced only to the extent that such expenses were reduced for Class A shares. In addition, under the management and administration agreements, certain other services and costs, including accounting, regulatory reporting and insurance premiums, are paid by the Trust. At June 30, 2004, $128,414 was payable to PIM related to management fees, administrative fees and certain other services, and is included in due to affiliates. -12- 5. Transfer Agent PIMSS, a wholly owned indirect subsidiary of UniCredito Italiano, provides substantially all transfer agent and shareowner services to the Trust at negotiated rates. Included in due to affiliates is $105,634 in transfer agent fees payable to PIMSS at June 30, 2004. 6. Distribution and Service Plans The Trust adopted Plans of Distribution with respect to each class of shares (Class A Plan, Class B Plan, Class C Plan, and Class R Plan) in accordance with Rule 12b-1 of the Investment Company Act of 1940. Pursuant to the Class A Plan, the Trust pays PFD a service fee of up to 0.25% of the Trust's average daily net assets attributable to Class A shares in reimbursement of such expenditures to finance activities primarily intended to result in the sale of Class A shares. Pursuant to the Class B Plan and the Class C Plan, the Trust pays PFD 1.00% of the average daily net assets attributable to each class of shares. The fee consists of a 0.25% service fee and a 0.75% distribution fee paid as compensation for personal services and/or account maintenance services or distribution services with regard to Class B and Class C shares. Pursuant to the Class R Plan, the Trust pays PFD 0.50% of the average daily net assets attributable to Class R shares for distribution services. Included in due to affiliates is $100,070 in distribution fees payable to PFD at June 30, 2004. The Trust also has adopted a separate service plan for Class R shares (Service Plan). The Service Plan authorizes the Trust to pay securities dealers, plan administrators or other services organizations that agree to provide certain services to retirement plans or plan participants holding shares of the Trust a service fee of up to 0.25% of the Trust's daily net assets attributable to Class R shares held by such plans. In addition, redemptions of each class of shares (except Investor Class shares) may be subject to a contingent deferred sales charge (CDSC). A CDSC of 1.00% may be imposed on redemptions of certain net asset value purchases of Class A shares within one year of purchase. Class B shares that are redeemed within six years of purchase are subject to a CDSC at declining rates beginning at 4.00%, based on the lower of cost or market value of shares being redeemed. Redemptions of Class C shares within one year of purchase are subject to a CDSC of 1.00%. Redemptions of Class R shares within 18 months of purchase may be subject to a CDSC of 1.00%. Proceeds from the CDSCs are paid to PFD. For the 12 months ended June 30, 2004, CDSCs in the amount of $373,990 were paid to PFD. Investor Class shares will not be subject to shareholder servicing or distribution fees. Investor Class shares will convert to Class A shares 24 months after the date on which the acquisition is completed. 7. Expense Offset Arrangements The Trust has entered into certain expense offset arrangements with PIMSS, resulting in a reduction in the Trust's total expenses due to interest earned on cash held by PIMSS. For the 12 months ended June 30, 2004, the Trust's expenses were reduced by $6,000 under such arrangements. -13- PIONEER AMERICA INCOME TRUST PRO FORMA Schedule of Investments (a) December 31, 2003

General The accompanying pro forma combined financial statements are presented to show the effect of the proposed acquisition (the "acquisition") of Safeco Intermediate-Term U.S. Government Fund by Pioneer America Income Trust. Under the terms of an Agreement and Plan of Reorganization between the Funds, the combination of Pioneer America Income Trust and Safeco Intermediate-Term U.S. Government 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 Safeco Intermediate-Term U.S. Government Fund in exchange for a new "Investor Class" of shares of Pioneer America Income Trust at net asset value, which will be established upon consummation of the merger. The accompanying schedules of investments, statements of assets and liabilities and the related statements of operations of Pioneer America Income Trust and Safeco Intermediate-Term U.S. Government Fund have been combined as of and for their most recent fiscal year ended December 31, 2003. Adjustments have been made to expenses for duplicate services that would not have been incurred if the merger took place on January 1, 2003. Following the acquisition, the Pioneer America Income 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 Pioneer America Income Trust and Safeco Intermediate-Term U.S. Government Fund included in their respective annual reports to shareowners dated December 31, 2003. 2. Organization and Significant Accounting Policies 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. After the merger, the Trust will consist of five classes of shares - Class A, Class B, Class C, Class R and Investor Class shares. Class R shares were first publicly offered on April 1, 2003. Investor Class shares are being offered as part of the acquisition. Shares of Class A, Class B, Class C, Class R and Investor Class each represent an interest in the same portfolio of investments of the Trust and have equal rights to voting, redemptions, dividends and liquidation, 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 Investor Class shares. Each Fund's management has prepared their respective financial information using estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the pro forma financial statements, and the reported amounts of income, expenses and gains and losses on investments during the reporting periods. Actual results could differ from those estimates. The following is a summary of significant accounting policies consistently followed by the Trust, which are in conformity with those generally accepted in the investment company industry: -20- A. Security Valuation Security transactions are recorded as of trade date. Securities are valued at prices supplied by independent pricing services, which consider such factors as Treasury spreads, yields, maturities and ratings. Valuations may be supplemented by dealers and other sources, as required. Securities for which there are no other readily available valuation method are valued at their fair values as determined by, or under the direction of the Trust's Board of Trustees. At December 31, 2003, there were no securities fair valued. 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 pay downs. 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. Gains and losses on sales of investments are calculated on the identified cost method for both financial reporting and federal income tax purposes. B. Federal Income Taxes Each fund has previously elected to be taxed as a "regulated investment company" under the Internal Revenue Code. After the acquisition, it will 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 combined capital loss carryforward of $8,538,000 includes a net capital loss carryforward of $1,398,000 from the merger with Safeco Intermediate-term U.S. Government Fund, the full use of which may be limited. C. Fund Shares The Trust records sales and repurchases of its shares as of trade date. Pioneer Funds Distributor, Inc. (PFD), the principal underwriter for the Trust and a wholly owned indirect subsidiary of UniCredito Italiano S.p.A. (UniCredito Italiano), earned $65,614 in underwriting commissions on the sale of Trust shares for the year ended December 31, 2003. D. Class Allocations Distribution fees are calculated based on the average daily net asset value attributable to Class A, Class B, Class C, Class R, and Investor Class shares of the Trust, respectively. Shareowners of each class share all expenses and fees paid to the transfer agent, Pioneer Investment Management Shareholder Services, Inc. (PIMSS), for its services, which are allocated based on the number of accounts in each class and the ratable allocation of related out-of-pocket expenses (see Note 5). Income, common expenses and realized and unrealized gains and losses are calculated at the Trust level and allocated daily to each class of shares based on the respective percentage of adjusted net assets at the beginning of the day. The Trust declares as daily dividends substantially all of its net investment income. All dividends are paid on a monthly basis. Short-term capital gain distributions, if any, may be declared with the daily dividends. Distributions to shareowners are recorded as of the ex-dividend date. Distributions paid by the Trust with respect to each class of shares are calculated in the same manner, at the same time, and in the same amount, except that Class A, Class B, Class C, Class R, and Investor Class shares can bear different transfer agent and distribution fees. E. Repurchase Agreements With respect to repurchase agreements entered into by the Trust, the value of the underlying securities (collateral), including accrued interest received from counter parties, is required to be at least equal to or in excess of the value of the repurchase agreement at the time of purchase. The collateral for all repurchase agreements is held in safekeeping in the customer-only account of the Trust's custodian, or sub custodians. The Trust's investment adviser, Pioneer Investment Management, Inc. (PIM) is responsible for determining that the value of the collateral remains at least equal to the repurchase price. -21- 3. 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, 2003, in connection with the proposed acquisition. The number of the shares assumed to be issued is equal to the net asset value of Safeco Intermediate-Term U.S. Government Fund, as of December 31, 2003, divided by the net asset value per share of the Investor Class shares of the Trust as of December 31, 2003. The pro forma number of shares outstanding (in thousands), by class, for the combined fund consist of the following at December 31, 2003: Shares of Additional Shares Total Outstanding the Trust Assumed Issued Shares Class of Shares Pre-Combination In Reorganization Post-Combination - --------------- --------------- ----------------- ---------------- Class A 15,468 15,468 Class B 5,591 5,591 Class C 3,775 3,775 Class R 33 33 Investor Class - 7,492 7,492 -22- 4. Management Agreement PIM manages the Trust's portfolio and is a wholly owned indirect subsidiary of UniCredito Italiano. Management fees are calculated daily at the annual rate of 0.50% of the Trust's average daily net assets. PIM discontinued the Fund's expense limitation on May 1, 2003. Prior to May 1, 2003, PIM had agreed not to impose a portion of its management fee and to assume other operating expenses of the Trust to the extent necessary to limit Class A expenses to 1.00% of the average daily net assets attributable to Class A shares; the portion of the Trust-wide expenses attributable to Class B, Class C and Class R shares were reduced only to the extent that such expenses were reduced for Class A shares. In addition, under the management and administration agreements, certain other services and costs, including accounting, regulatory reporting and insurance premiums, are paid by the Trust. At December 31, 2003, $158,222 was payable to PIM related to management fees, administrative fees and certain other services, and is included in due to affiliates. 5. Transfer Agent PIMSS, a wholly owned indirect subsidiary of UniCredito Italiano, provides substantially all transfer agent and shareowner services to the Trust at negotiated rates. Included in due to affiliates is $77,973 in transfer agent fees payable to PIMSS at December 31, 2003. 6. Distribution and Service Plans The Trust adopted Plans of Distribution with respect to each class of shares (Class A Plan, Class B Plan, Class C Plan, and Class R Plan) in accordance with Rule 12b-1 of the Investment Company Act of 1940. Pursuant to the Class A Plan, the Trust pays PFD a service fee of up to 0.25% of the Trust's average daily net assets attributable to Class A shares in reimbursement of such expenditures to finance activities primarily intended to result in the sale of Class A shares. Pursuant to the Class B Plan and the Class C Plan, the Trust pays PFD 1.00% of the average daily net assets attributable to each class of shares. The fee consists of a 0.25% service fee and a 0.75% distribution fee paid as compensation for personal services and/or account maintenance services or distribution services with regard to Class B and Class C shares. Pursuant to the Class R Plan, the Trust pays PFD 0.50% of the average daily net assets attributable to Class R shares for distribution services. Included in due to affiliates is $127,966 in distribution fees payable to PFD at December 31, 2003. The Trust also has adopted a separate service plan for Class R shares (Service Plan). The Service Plan authorizes the Trust to pay securities dealers, plan administrators or other services organizations that agree to provide certain services to retirement plans or plan participants holding shares of the Trust a service fee of up to 0.25% of the Trust's daily net assets attributable to Class R shares held by such plans. In addition, redemptions of each class of shares (except Investor Class shares) may be subject to a contingent deferred sales charge (CDSC). A CDSC of 1.00% may be imposed on redemptions of certain net asset value purchases of Class A shares within one year of purchase. Class B shares that are redeemed within six years of purchase are subject to a CDSC at declining rates beginning at 4.00%, based on the lower of cost or market value of shares being redeemed. Redemptions of Class C shares within one year of purchase are subject to a CDSC of 1.00%. Redemptions of Class R shares within 18 months of purchase may be subject to a CDSC of 1.00%. Proceeds from the CDSCs are paid to PFD. For the year ended December 31, 2003, CDSCs in the amount of $383,960 were paid to PFD. Investor Class shares will not be subject to shareholder servicing or distribution fees. Investor Class shares will be converted to Class A shares 24 months after the date on which the acquisition is completed. 7. Expense Offset Arrangements The Trust has entered into certain expense offset arrangements with PIMSS, resulting in a reduction in the Trust's total expenses due to interest earned on cash held by PIMSS. For the year ended December 31, 2003, the Trust's expenses were reduced by $8,000 under such arrangements. -23- PART C OTHER INFORMATION PIONEER AMERICA INCOME TRUST ITEM 15.
