Anxiety over energy prices, international tensions and the falling American dollar had held the markets back, but uneasiness about the presidential election was the principal source of investor hesitation. The election went smoothly, the result was decisive, and the ensuing rally pushed major indices into the black for the second year running. However, returns trailed 2003's levels. Small capitalization companies outperformed large cap issues for the sixth consecutive year. Markets overseas were generally buoyant: commodity-rich nations saw surging demand for copper, gold, lumber and other materials, with much of their output destined to feed China's vast economic appetite. Bond investors focused on longer-term issues. Reflecting the risk aversion that favored small cap stocks, high-yield bonds were the strongest performers, while higher quality issues, including U.S. Treasury issues, scored more modest gains. Municipal bond returns were generally favorable as well; economic growth spurred rising tax revenues, putting many issuers into surplus for the first time in years. A measured pace of growth seems in store for the U.S. economy, which generated 2.2 million jobs after years of employment declines. By the end of September, the economy had tallied twelve straight up quarters and the nation's annualized growth rate stood at a respectable four percent. We believe this rate of expansion is enough to sustain growth without provoking the Federal Reserve Board into aggressive interest rate hikes aimed at calming inflation.

Investment return and principal value will fluctuate, and shares, when redeemed, may be worth more or less than their original cost. Performance for periods prior to the inception of Y shares reflects the NAV performance of the Fund's A shares. The performance does not reflect differences in expenses, including the Rule 12b-1 fees applicable to A shares. Since fees for A shares are generally higher than those of Y shares, the performance shown for Y shares prior to their inception would have been higher. Class A shares are used as a proxy from 10/31/78 to 9/20/01. Class Y shares are not subject to sales charges and are available for limited groups of eligible investors, including institutional investors. All results are historical and assume the reinvestment of dividends and capital gains. Other share classes are available for which performance and expenses will differ.

Certain Pioneer funds (the "Funds") issued Investor Class shares in connection with the reorganization of Safeco mutual funds. The Funds are not offering additional Investor Class shares except in connection with the reinvestment of dividends on the Funds' outstanding Investor Class shares. All Investor Class shares of the Funds, whenever issued, convert to Class A shares of their respective Funds on December 10, 2006. Investor Class shares are not subject to sales charges. Performance results reflect any applicable expense waivers in effect during the periods shown. Without such waivers Fund performance would be lower. Waivers may not be in effect for all funds.

The performance table does not reflect the deduction of fees and taxes that a shareowner would pay on Fund distributions or the redemption of Fund shares. 8 Pioneer Bond Fund ================================================================================ COMPARING ONGOING FUND EXPENSES ================================================================================ As a shareowner in the Fund, you incur two types of costs: (1) ongoing costs, including management fees, distribution and/or service (12b-1) fees, and other Fund expenses; and (2) transaction costs, including sales charges (loads) on purchase payments. This example is intended to help you understand your ongoing expenses (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 at the beginning of the Fund's latest six-month period and held throughout the six months. Using the Tables Actual Expenses The first table below provides information about actual account values and actual expenses. You may use the information in this table, together with the amount you invested, to estimate the expenses that you paid over the period as follows: 1. Divide your account value by $1,000 Example: an $8,600 account value [divide] $1,000 = 8.6 2. Multiply the result in (1) above by the corresponding share class's number in the third row under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. Expenses Paid on a $1,000 Investment in Pioneer Bond Fund Based on actual returns from July 1, 2004 through December 31, 2004 Investor Share Class A B C R Y Class - ------------------------------------------------------------------------------------------------ Beginning Account Value On 7/1/04** $1,000.00 $1,000.00 $1,000.00 $1,000.00 $1,000.00 $1,000.00 Ending Account Value (after expenses) On 12/31/04 $1,049.20 $1,045.00 $1,045.40 $1,047.10 $1,052.20 $1,001.90 Expenses Paid During Period* $ 5.68 $ 10.31 $ 10.05 $ 7.33 $ 3.10 $ 0.45 * Expenses are equal to the Fund's annualized expense ratio of 1.10%, 2.00%, 1.95%, 1.42%, 0.60% and 0.87%, for Class A, Class B, Class C, Class R, Class Y, and Investor Class shares, respectively, multiplied by the average account value over the period, multiplied by 184/365 (to reflect the one-half year period) 21/366 for Investor Class shares. ** 12/11/04 for Investor Class shares. 9 Pioneer Bond Fund ================================================================================ ================================================================================ Hypothetical Example for Comparison Purposes The table below provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the tables are meant to highlight your ongoing costs only and do not reflect any transaction costs, such as sales charges (loads).. Therefore, the table below is useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds. In addition, if these transaction costs were included, your costs would have been higher. Expenses Paid on a $1,000 Investment in Pioneer Bond Fund Based on a hypothetical 5% per year return before expenses, reflecting the period from July 1, 2004 through December 31, 2004 Investor Share Class A B C R Y Class - ----------------------------------------------------------------------------------------------- Beginning Account Value On 7/1/04 $1,000.00 $1,000.00 $1,000.00 $1,000.00 $1,000.00 $1,000.00 Ending Account Value (after expenses) On 12/31/04 $1,019.66 $1,015.12 $1,015.38 $1,018.05 $1,022.18 $1,002.15 Expenses Paid During Period* $ 5.60 $ 10.16 $ 9.91 $ 7.22 $ 3.06 $ 0.45 * Expenses are equal to the Fund's annualized expense ratio of 1.10%, 2.00%, 1.95%, 1.42%, 0.60%, and 0.87%, for Class A, Class B, Class C, Class R, Class Y, and Investor Class shares, respectively, multiplied by the average account value over the period, multiplied by 184/365 (to reflect the one-half year period). 10 Pioneer Bond Fund ================================================================================ PORTFOLIO MANAGEMENT DISCUSSION 12/31/04 ================================================================================ As the domestic economy showed evidence of a sustained recovery during the second half of 2004, the U.S. Federal Reserve continued to raise short-term interest rates gradually to contain the risk of inflation and keep the economy in check. The fixed-income market reacted favorably to the Fed's series of measured increases in the Fed funds rate, with the yields of longer-term Treasuries actually declining modestly. Meanwhile corporate bonds and mortgages continued to outperform Treasuries as investors sought out higher-yielding investments in an environment of low, by historical standards, interest rates. In the following discussion, Kenneth J. Taubes discusses the factors that influenced Pioneer Bond Fund's performance during the six months. Mr. Taubes, Director of Pioneer's Fixed Income Group, oversees the team responsible for daily management of the Fund. Q: How did the Fund perform during six months ended December 31, 2004? A: Pioneer Bond Fund performed well, outpacing its benchmark as well as the competitive funds average. For the six-month period, the Fund's Class A shares returned 4.92%, at net asset value. During the same six months, the Lehman Brothers Aggregate Bond Index returned 4.18%, while the average total return of the 224 funds in Lipper's Corporate Debt A-Rated Bond Fund category was also 4.18%. On December 31, 2004, the standardized 30-day SEC Yield on Class A shares was 4.00%. The performance data quoted represents past performance, which is no guarantee of future results. Investment return and principal value will fluctuate, and shares, when redeemed, may be worth more or less than their original cost. Q: What factors affected Fund performance? A: During a period in which investors sought out yield, the Fund held to its emphasis on sectors with yield advantages over Treasuries, corporate bonds and mortgage-backed securities. Both corporate bonds and mortgage securities outperformed Treasuries, with high-yield corporate securities turning in the best performance of all sectors of the domestic bond market. Despite rising short-term rates, the yields of longer maturity Treasuries were relatively stable, and investors sought out securities with yield advantages 11 Pioneer Bond Fund ================================================================================ PORTFOLIO MANAGEMENT DISCUSSION 12/31/04 (continued) ================================================================================ over Treasuries. Against a backdrop of a strengthening economy, corporations generated additional cash flow, which improved the overall credit quality of corporate securities and further encouraged investments in both high-yield and investment-grade corporate debt. Our emphasis on high-yield and investment-grade corporate bonds as well as mortgage securities helped support Fund performance throughout the six months. At the end of the six-month period, about 55% of assets were invested in mortgage securities and about 40% were invested in corporate debt, including almost 15% high-yield bonds. We reduced our high-yield positions slightly in the final quarter of the year. As we did so, we increased our investments in mortgages, which offered yields competitive with investment-grade corporates but with higher quality. Overall average credit quality of the portfolio was raised slightly during the period from A to A+. Less significant but also helpful was our decision to keep the Fund's sensitivity to interest-rate changes -- as measured by duration -- either neutral or slightly longer than the benchmark Lehman Brothers Aggregate Bond Index. In an environment of stable to slightly-declining market interest rates, this strategy tended to benefit performance. On December 31, 2004, the Fund's average effective duration was a somewhat shorter 3.99 years. Q: What were some of the individual holdings that most influenced portfolio performance? A: Among the high-yield holdings that helped performance were the bonds of two steel companies: International Steel, which we sold to take profits before the period ended, and ISPAT Inland ULC, which were upgraded in credit rating after the company was acquired by a Dutch corporation. Other bonds which appreciated strongly in price were those of financial service corporates Allmerica Financial, E-Trade and Odyssey Re. Detracting from results were insurance company Provident, whose bond prices slipped amid controversy over the New York attorney general's investigation of industry practices, Toys "R" Us, which announced restructuring plans, and Intelsat, a satellite company that withdrew plans for an initial public stock offering. 12 Pioneer Bond Fund ================================================================================ ================================================================================ Q: What is your investment outlook? A: We anticipate that the Federal Reserve will continue to raise the Fed funds rate at a gradual pace during 2005. The fixed-income market already has anticipated, in current bond prices, a series of further increases that would bring the Fed funds rate from 2.25% to near 3.5% by the end of the year. We believe the market rates of longer-term and intermediate-term securities already are close to being fairly valued. As a result, we anticipate that the yield curve -- which measures the relationship between short-term and longer-term interest rates -- likely will flatten during the year as short-term rates move up. In general, valuations of corporate securities appear relatively high by historical standards, but they probably are justified given the strong economic fundamentals both in the United States and throughout the globe. Strengthening economies are now helping companies across all sectors, resulting in improved cash flows and corporate profits. In this environment, we think corporate bonds should perform well, consistent with their yield advantage over Treasuries. As a result, we will continue to look for opportunities in the corporate sector. However, we expect to also put greater emphasis on mortgage securities, which offer virtually the same yields as investment-grade corporate debt but have the advantage of higher credit ratings. Investments in high yield or lower-rated securities are subject to greater-than-average risk. When interest rates rise, the prices of fixed income securities in the Fund will generally fall. Conversely, when interest rates fall the prices of fixed-income securities in the Fund will generally rise. The portfolio may invest in mortgage-backed securities, which during times of fluctuating interest rates may increase or decrease more than other fixed-income securities. Mortgage-backed securities are also subject to pre-payments. Investments in the Fund are subject to possible loss due to the financial failure of underlying securities and their inability to meet their debt obligations. Any information in this shareholder report regarding market or economic trends or the factors influencing the Fund's historical or future performance are statements of the opinion of Fund management as of the date of this report. These statements should not be relied upon for any other purposes. Past performance is no guarantee of future results, and there is no guarantee that market forecasts discussed will be realized. 13 Pioneer Bond Fund ================================================================================ SCHEDULE OF INVESTMENTS 12/31/04 (unaudited) ================================================================================ Principal S&P/Moody's Amount Ratings USD ($) (unaudited) Value ASSET BACKED SECURITIES - 2.3% Diversified Financials - 1.2% Consumer Finance - 0.0% 31,958 AAA/Aaa Americredit Automobile Receivables Trust, Floating Rate Note, 12/12/07 $ 31,978 ---------- Diversified Financial Services - 1.2% 1,864,000 BBB-/Baa2 PF Export Receivable Master Trust, 6.436%, 6/1/15 (144A) $1,852,648 1,387,018 BBB/Baa2 Power Receivables Finance, 6.29%, 1/1/12 (144A) 1,459,767 ---------- $3,312,415 ---------- Specialized Finance - 0.0% 90,000 AAA/Aaa MBNA Credit Card Master Note, Floating Rate Note, 12/15/08 $ 90,123 ---------- Total Diversified Financials $3,434,516 ---------- Utilities - 1.0% Electric Utilities - 1.0% 1,700,000 BBB-/Baa3 Empresa Electric Guacolda, 8.625%, 4/30/13 (144A) $1,941,407 662,200 BB-/Ba2 FPL Energy Wind Funding, 6.876%, 6/27/17 (144A) 682,894 ---------- $2,624,301 ---------- Total Utilities $2,624,301 ---------- TOTAL ASSET BACKED SECURITIES (Cost $5,755,014) $6,058,817 ---------- COLLATERALIZED MORTGAGE OBLIGATIONS - 1.0% Diversified Financials - 1.0% Consumer Finance - 0.0% 7,110 AAA/Aaa Asset Securitization Corp., Floating Rate Note, 1/13/30 $ 7,132 ---------- Diversified Financial Services - 1.0% 2,175,000 BBB-/Baa3 Tower 2004-1A E, 5.395%, 1/15/34 $2,170,959 525,000 BB/NR Tower 2004-2A F, 6.376%, 12/15/14 522,375 ---------- Total Diversified Financials $2,693,334 ---------- TOTAL COLLATERALIZED MORTGAGE OBLIGATIONS (Cost $2,707,371) $2,700,466 ---------- The accompanying notes are an integral part of these financial statements. 14 Pioneer Bond Fund ================================================================================ ================================================================================ Principal S&P/Moody's Amount Ratings USD ($) (unaudited) Value CORPORATE BONDS - 35.6% Energy - 1.6% Integrated Oil & Gas - 0.0% 45,000 BBB/Baa2 Petro-Canada, 4.0%, 7/15/13 $ 42,153 25,000 BBB+/Baa1 USX Corp., 6.85%, 3/1/08 27,200 ---------- $ 69,353 ---------- Oil & Gas Exploration & Production - 0.8% 75,000 BBB-/Baa1 Pemex Project Funding Master, 9.125%, 10/13/10 $ 89,925 2,000,000 BBB-/NR Gazprom International SA., 7.201%, 2/1/20 (144A) 2,115,000 ---------- $2,204,925 ---------- Oil & Gas Refining Marketing & Transportation - 0.8% 65,000 BBB+/Baa1 Kinder Morgan Energy Partners, 6.75%, 3/15/11 $ 72,568 1,750,000 BBB/Ba1 Magellan Midstream Partners, L.P., 6.45%, 6/1/14 1,892,462 ---------- $1,965,030 ---------- Total Energy $4,239,308 ---------- Materials - 4.9% Commodity Chemicals - 1.1% 1,100,000 BBB-/Ba1 Methanex Corp., 8.75%, 8/15/12 $1,284,250 1,500,000 BB+/Ba2 Nova Chemicals, Ltd., 6.5%, 1/15/12 1,590,000 ---------- $2,874,250 ---------- Diversified Metals & Mining - 1.1% 2,575,000 BBB/Ba1 Kennametal, Inc., 7.2%, 6/15/12 $2,861,430 ---------- Fertilizers & Agricultural Chemicals - 0.0% 45,000 BBB+/Baa2 Potash Corp.

Organization and Significant Accounting Policies Pioneer Bond Fund (the Fund) is a Delaware statutory trust registered under the Investment Company Act of 1940 as a diversified, open-end management investment company. The investment objective of the Fund is to seek current income consistent with preservation of capital. The Trustees have authorized the issuance of six classes of shares of the Fund. The Fund offers six classes of shares designated as Class A, Class B, Class C, Investor Class, Class R, and Class Y shares. Class R shares were first publicly offered April 1, 2003. Investor Class shares were first publicly offered on December 10, 2004. The Fund is not offering additional Investor Class shares except in connection with the reinvestment of dividends on the Fund's Outstanding Investor Class shares. Each class of shares represents an interest in the same portfolio of investments of the Fund and has equal rights to voting, redemptions, dividends and liquidation, except that each class of shares can bear different transfer agent and distributions fees and has exclusive voting rights with respect to the distribution plans that have been adopted by Class A, Class B, Class C, and Class R shareowners, respectively. There is no distribution plan for Class Y shares and Investor Class shares. The Fund's financial statements have been prepared in conformity with U.S. generally accepted accounting principles that require the management of the Fund to, among other things, make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of income, expenses and gains and losses on investments during the reporting period. Actual results could differ from those estimates. The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements, which are consistent with those policies 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 methods are valued at their fair values as 43 Pioneer Bond Fund ================================================================================ NOTES TO FINANCIAL STATEMENTS 12/31/04 (unauditded) (continued) ================================================================================ determined by, or under the direction of the Board of Trustees. At December 31, 2004 there were no securities fair valued. Principal amounts of mortgage-backed securities are adjusted for monthly paydowns. Temporary cash investments are valued at amortized cost. All discounts/premiums on debt securities are accreted/amortized for financial reporting purposes over the life of the respective securities, and are included in interest income. Market discount and premium are accreted or amortized daily. Premiums and discounts related to certain mortgage-backed securities are amortized or accreted in proportion to the underlying monthly paydowns. Interest income is recorded on the accrual basis. 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 It is the Fund's policy to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its taxable income and net realized capital gains, if any, to its shareowners. Therefore, no federal income tax provision is required. The amounts and characterizations of distributions to shareowners for financial reporting purposes are determined in accordance with federal income tax rules. Therefore, the sources of the Fund's distributions may be shown in the accompanying financial statements as either from or in excess of net investment income or net realized gain on investment transactions, or from paid-in capital, depending on the type of book/tax differences that may exist. The tax character of current year distributions paid will be determined at the end of the current fiscal year. The tax character of distributions paid during the year ended December 31, 2004 was as follows: - ----------------------------------------- 2004 - ----------------------------------------- Distributions paid from: Ordinary income $13,862,071 Long-term capital gain - ----------- Total $13,862,071 ----------- ========================================= 44 Pioneer Bond Fund ================================================================================ ================================================================================ The following shows the components of distributable earnings on a federal income tax basis at December 31, 2004. - ------------------------------------------------ 2004 - ------------------------------------------------ Undistributed ordinary income $ 881,220 Dividends payable $ (229,477) Capital loss-carryforward $(6,403,162) Unrealized appreciation $ 2,826,845 ----------- Total $(2,924,574) ----------- ================================================ The difference between book basis and tax-basis unrealized appreciation is attributable to the tax deferral of losses on wash sales and the tax treatment of amortization. C. Fund Shares The Fund records sales and repurchases of its shares as of trade date. Pioneer Funds Distributor, Inc. (PFD), the principal underwriter for the Fund and a wholly owned indirect subsidiary of UniCredito Italiano S.p.A., (UniCredito Italiano), earned $25,658 in underwriting commissions on the sale of Class A shares during the six months ended December 31, 2004. D. Class Allocations Distribution fees are calculated based on the average daily net asset value attributable to Class A, Class B, Class C, and Class R shares of the Fund, respectively. Class Y and Investor Class shares are not subject to a distribution plan. 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 3). Income, common expenses, and realized and unrealized gains and losses are calculated at the Fund 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 Fund 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 45 Pioneer Bond Fund ================================================================================ NOTES TO FINANCIAL STATEMENTS 12/31/04 (unauditded) (continued) ================================================================================ of the ex-dividend date. Distributions paid by the Fund 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, Investor Class, Class R and Class Y shares can bear different transfer agent and distribution fees. E. Repurchase Agreements With respect to repurchase agreements entered into by the Fund, the value of the underlying securities (collateral), including accrued interest received from the counterparties, 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 Fund's custodian, or subcustodians. The Fund'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. F. Securities Lending The Fund lends securities in its portfolio to certain broker-dealers or other institutional investors, with the Fund's custodian acting as the lending agent. When entering into a loan, the Fund receives collateral, which is maintained by the custodian and earns income in the form of negotiated lenders' fees. The Fund also continues to receive interest or payments in lieu of dividends on the securities loaned. Gain or loss on the fair value of the loaned securities that may occur during the term of the loan will be for the account of the Fund. The loans are secured by collateral of at least 102% at all times, of the fair value of the securities loaned. The amount of the collateral will be adjusted daily to reflect any price fluctuation in the value of loaned securities. The Fund has the right under the lending agreements to recover the securities on loan from the borrower on demand. The Fund invests cash collateral in the Securities Lending Investment Fund, which is managed by Brown Brothers Harriman & Co., the Fund's custodian. 2. Management Agreement PIM, a wholly owned indirect subsidiary of UniCredito Italiano, manages the Fund's portfolio. Management fees are calculated daily at the annual rate of 0.50% of the Fund's average daily net assets. In 46 Pioneer Bond Fund ================================================================================ ================================================================================ addition, under the management and administration agreements, certain other services and costs, including accounting, regulatory reporting, and insurance premiums, are paid by the Fund. At December 31, 2004, $119,533 was payable to PIM related to management fees, administrative costs and certain other services, and is included in due to affiliates. Through December 10, 2006, PIM has agreed not to impose all or a portion of its management fee and to assume other operating expenses (excluding taxes, commissions, interest and extraordinary expenses) of the Fund to the extent necessary to limit Investor Class expenses to 0.74% of the average daily net assets attributable to Investor Class shares. 3. Transfer Agent PIMSS, a wholly owned indirect subsidiary of UniCredito Italiano, provides substantially all transfer agent and shareowner services to the Fund at negotiated rates. Included in due to affiliates is $99,738 in transfer agent fees payable to PIMSS at December 31, 2004. 4. Distribution and Service Plans The Fund adopted a Plan 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 Fund pays PFD a service fee of up to 0.25% of the average daily net assets attributable to Class A shares in reimbursement of its actual 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 Fund 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 Fund pays PFD 0.50% of the average daily net assets attributable to Class R shares for distribution services. Included in due to affiliates is $108,525 in distribution fees payable to PFD at December 31, 2004. The Fund also has adopted a separate service plan for Class R shares (Service Plan). The Service Plan authorizes the Fund to pay securities dealers, plan administrators or other service organizations that agree to 47 Pioneer Bond Fund ================================================================================ NOTES TO FINANCIAL STATEMENTS 12/31/04 (unauditded) (continued) ================================================================================ provide certain services to retirement plans or plan participants holding shares of the Fund a service fee of up to 0.25% of the Fund's average daily net assets attributable to Class R shares held by such plans. In addition, redemptions of Class A, Class B, Class C and Class R shares may be subject to a contingent deferred sales charge (CDSC). Effective February 1, 2004 a CDSC of 1.00% may be imposed on redemptions of certain net asset value purchases of Class A shares within 18 months of purchase (12 months for shares purchased prior to February 1, 2004). Effective December 1, 2004, Class B shares that are redeemed within five 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. Shares purchased prior to December 1, 2004 remain subject to the CDSC in effect at the time those shares were purchased. 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 were subject to a CDSC of 1.00%. Effective July 1, 2004 the CDSC on Class R shares was eliminated. Proceeds from the CDSCs are paid to PFD. For the six months ended December 31, 2004, $71,576 in CDSCs were paid to PFD. 5. Expense Offset Arrangements The Fund has entered into certain expense offset arrangements with PIMSS resulting in a reduction in the Fund's total expenses due to interest earned on cash held by PIMSS. For the six months ended December 31, 2004, the Fund's expenses were reduced by $1,945 under such arrangements. 48 Pioneer Bond Fund ================================================================================ ================================================================================ 6.

PIONEER FUNDS APPROVAL OF AUDIT, AUDIT-RELATED, TAX AND OTHER SERVICES PROVIDED BY THE INDEPENDENT AUDITOR SECTION I - POLICY PURPOSE AND APPLICABILITY The Pioneer Funds recognizes the importance of maintaining the independence of their outside auditors. Maintaining independence is a shared responsibility involving Pioneer Investment Management, Inc ("PIM"), the audit committee and the independent auditors. The Funds recognizes that a Fund's independent auditors: 1) possess knowledge of the Funds, 2) are able to incorporate certain services into the scope of the audit, thereby avoiding redundant work, cost and disruption of Fund personnel and processes, and 3) have expertise that has value to the Funds. As a result, there are situations where it is desirable to use the Fund's independent auditors for services in addition to the annual audit and where the potential for conflicts of interests are minimal. Consequently, this policy, which is intended to comply with Rule 210.2-01(C)(7), sets forth guidelines and procedures to be followed by the Funds when retaining the independent audit firm to perform audit, audit-related tax and other services under those circumstances, while also maintaining independence. Approval of a service in accordance with this policy for a Fund shall also constitute approval for any other Fund whose pre-approval is required pursuant to Rule 210.2-01(c)(7)(ii). In addition to the procedures set forth in this policy, any non-audit services that may be provided consistently with Rule 210.2-01 may be approved by the Audit Committee itself and any pre-approval that may be waived in accordance with Rule 210.2-01(c)(7)(i)(C) is hereby waived. Selection of a Fund's independent auditors and their compensation shall be determined by the Audit Committee and shall not be subject to this policy.

N/A (f) If greater than 50 percent, disclose the percentage of hours expended on the principal accountant's engagement to audit the registrant's financial statements for the most recent fiscal year that were attributed to work performed by persons other than the principal accountant's full-time, permanent employees. N/A (g) Disclose the aggregate non-audit fees billed by the registrant's accountant for services rendered to the registrant, and rendered to the registrant's investment adviser (not including any sub-adviser whose role is primarily portfolio management and is subcontracted with or overseen by another investment adviser), and any entity controlling, controlled by, or under common control with the adviser that provides ongoing services to the registrant for each of the last two fiscal years of the registrant. The Fund's independent auditor, Ernst & Young LLP ("E&Y"), recently has advised the Securities and Exchange Commission, the Public Company Accounting Oversight Board, and the Audit Committee of the Fund's Board of Trustees that certain non-audit work performed by E&Y's China affiliate has raised questions regarding E&Y's independence with respect to its performance of audit services for the Fund. In July 2004, E&Y became aware that member firms in China ("E&Y China") provided certain tax services to offices of UniCredito Italiano, S.p.A. ("UCI"), a member of the Fund's Investment Company Complex. The services included receipt and disbursement of monies transferred to E&Y China by UCI in payment of individual expatriate income taxes due on returns prepared by E&Y China for certain UCI employees located in China from October 1998 to May 2003. E&Y became auditors of the Fund in May 2002. These expatriate tax services were discontinued in May 2003. The fees received by E&Y China for all such services totaled $3,685. The Fund's Audit Committee and E&Y have discussed the matter, including the nature of the services provided, the personnel involved in providing the services and the fees received by E&Y for performing the services. The Committee continues to review the facts and circumstances surrounding the matter, including the issue of whether the monies transferred for employees' taxes were de facto monies due the employees for tax payments rather than monies belonging to UCI. E&Y has informed the Audit Committee that based on its internal reviews and the de minimis nature of the services provided and fees received, it does not believe its independence with respect to the Fund has been impaired. (h) Disclose whether the registrant's audit committee of the board of trustees has considered whether the provision of non-audit services that were rendered to the registrant's investment adviser (not including any subadviser whose role is primarily portfolio management and is subcontracted with or overseen by another investment adviser), and any entity controlling, controlled by, or under common control with the investment adviser that provides ongoing services to the registrant that were not pre-approved pursuant to paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X is compatible with maintaining the principal accountant's independence.
