Mr. Hood, formerly Pioneer's Chief Operating Officer and a key member of the senior management committee, joined Pioneer in 2000 from John Hancock Financial Services, where he had held senior financial positions. "I am excited and honored to have the opportunity to lead Pioneer as it continues to grow," Mr. Hood said. "As CEO I look forward to furthering Pioneer's strategic goals, including developing new products that can meet the wider needs of investors and the advisers who serve them." [end sidebar] With the fading of concerns over the Iraq war, investors whose attention had been focused overseas were buoyed this spring by hints of increased economic activity at home. The nation's stock markets began a broad-based rally in early March, and prices continued to climb. From April through June, the major stock market averages recorded one of the biggest quarterly jumps in years. Increasing investor confidence also led to strong returns on corporate bonds. However, returns on government bonds, which rose sharply earlier, have slowed. Encouraging factors aren't hard for investors to find. The lowest interest rates many of us have ever seen and the administration's tax cuts mean higher incomes for many consumers. The tax reductions on dividends and capital gains are of special interest to investors. Corporations can also borrow at the lowest rates in years. Many companies are realizing substantial savings by replacing old, high-cost debt with new issues that carry lower interest. The Federal Reserve Board cut rates once again in June in an effort to inject further stimulus into the economy. And the weak U.S. dollar helps exporters and multinational companies operating in countries with stronger currencies. One possible lesson to be learned from the market's decline and recovery is the importance of staying invested. Those who stayed with their commitments benefitted from a stock market rally and a strong rise in corporate bonds, while those who remained on the sidelines had to play catch-up. If the protracted slump caused your investment discipline to slip, this may be an ideal time to contact your financial advisor for guidance on resuming your investment program and determining the right balance for you among stocks, bonds and short-term investments. Our style focuses on companies, not on forecasts There are always risks, of course, and the direction of the economy is something of a puzzle at the moment. If it continues to struggle for very long, investors may once again seek shelter in short-term commitments. However, Pioneer's portfolio managers and analysts do not base investment decisions on economic assumptions. Instead, as it has since our founding in 1928, our value-focused investment style requires complete understanding of a company and its potential. That means intensive analysis of financial reports, visits to companies and detailed discussions with corporate managers. When we discover potential that appears to exceed the market's valuation, that company's stocks and bonds may become candidates for investment. Our research efforts are aided in no small measure by the global resources of our parent organization, UniCredito Italiano, S.p.A. Like everyone at Pioneer, I appreciate your continued confidence in our products and services. Respectfully, /s/ Osbert M. Hood Osbert M. Hood Pioneer Investment Management, Inc.

High-grade bonds turned in outstanding performance early in the period as interest rates fell, while corporate bonds excelled later amid rising expectations for an economic recovery. In the following discussion, Kenneth J. Taubes details the factors that influenced Pioneer Bond Fund's performance during the 12-month period. Mr. Taubes, head 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, 2003? A: The Fund performed strongly, outpacing its benchmarks during a favorable period for fixed income investments. For the 12 months ended June 30, 2003, The Fund's Class A shares had a total return of 11.38% at net asset value, while Class B and Class C shares returned 10.44% and 10.28%, respectively. During the same period, the Lehman Aggregate Bond Index had a return of 10.40%. On June 30, 2003, the 30-day SEC yield on Class A shares was 3.56%. Q: What were the principal factors that influenced performance during the year? A: Our emphasis on corporate bonds was a major factor in the Fund's strong performance, especially after October 2002, when corporate securities began rising on hopes of improving economic conditions. However, our Treasury and mortgage holdings also did well on an absolute basis. In addition, we kept the Fund's duration - or sensitivity to interest-rate changes - higher than the Lehman Brothers benchmark for most of the period. This strategy added to performance during a year in which interest rates declined and bond prices rose. Falling interest rates had the greatest direct impact on Treasuries and other high-grade bonds. Over the full period, the yields of 30-year Treasuries fell by almost one percentage point (0.92%), while the yields of 10-year Treasuries declined by 1.27 percentage points and those of three-year Treasuries plummeted by 1.81 percentage points. These declines were in anticipation of short-term interest rate cuts by the U.S. Federal Reserve, which continued its accommodative monetary policy in an effort to boost the economy. 8 Pioneer Bond Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- Most of the declines in rates came early in the period, which was when Treasuries and other high-grade bonds had their best performance. For the full year, high-yielding corporate securities performed even better than high-grade securities, with lower-quality bonds outpacing investment-grade corporates. The Merrill Lynch High Yield Master Index, for example, rose by more than 20% for the year, while the Merrill Lynch Investment Grade Corporate Index delivered a total return of more than 16%. Corporate bonds delivered most of their performance after October 2002. Investors correctly anticipated that the Federal Reserve would make further cuts in short-term rates, easing the flow of money into the economy. In addition, evidence began accumulating that the business sector had begun to stabilize. Many corporations had cut their overhead expenses, repaired their balance sheets and refinanced their debt to take advantage of lower interest rates. In addition, the weakening of the U.S. dollar on international currency exchanges tended to help corporations, especially those selling products overseas and those competing domestically against imported goods. Lagging corporate bonds and Treasuries were mortgage-backed securities, the performance of which was affected by the wave of mortgage refinancing precipitated by falling interest rates. But even mortgages delivered healthy, positive returns for the 12 months. Q: What were your chief strategies? A: We kept the Fund fully invested, with emphasis on corporate securities, both investment grade and high yield. At the end of the fiscal year, on June 30, 2003 more than 58% of Fund assets were invested in corporate bonds, including 18.4% in high-yield securities. Mortgage-backed securities accounted for another 24% of Fund assets, while 10% was invested in Treasury securities. The Fund's duration on June 30, 2003 was 4.7 years, high relative to the Lehman index. For much of the period, we maintained an even higher duration. 9 Pioneer Bond Fund - -------------------------------------------------------------------------------- PORTFOLIO MANAGEMENT DISCUSSION 6/30/03 (continued) - -------------------------------------------------------------------------------- Average credit quality on June 30, 2003 was A-, slightly less than the A average on December 31, 2002. The difference reflected our increased emphasis on corporate bonds. Q: What type of investments most influenced performance? A: While just about every type of investment had good performance, we had particularly favorable results from some of our newer holdings in the telecommunications and utility industries. We had maintained very small weightings in telecommunications during that industry's slump, and we also had de-emphasized the utility sector because of the well publicized problems of energy merchant companies in the wake of the Enron scandal. We began adding to our telecommunications positions during the period, focusing on those companies that we believed would be the industry survivors. Our investments in the bonds of companies such as AT&T Wireless and Sprint were particularly successful. We also found some attractive utility bonds that turned into performance leaders, including those of Constellation Energy and Dominion Resources. CMS Panhandle bonds, issued by an energy pipeline company, also gained when the company was involved in a merger and the securities were upgraded from high yield to investment grade. Our Allmerica Financial bond holdings also performed very well. The company's bonds started to recover after declining because of investor fears about the exposure of Allmerica's variable annuity business to the declining equity markets. Two detractors from performance were our holdings in HealthSouth and in UAL bonds, both of which were modest positions for the Fund. HealthSouth's securities fell amid allegations of financial statement fraud, while the UAL bonds were pulled down by concerns about the future of the commercial airline industry and the company's ultimate bankruptcy filing. 10 Pioneer Bond Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- Q: What is your investment outlook for the bond market? A: We believe interest rates may be near their low points. As a result we have begun to decrease the Fund's exposure to interest-rate risk by lowering duration. We also have reduced our exposure to rate increases by cutting our Treasury positions and increasing our mortgage holdings, where we think the risks from prepayments have been reflected in the securities prices. In the absence of any unanticipated major events, we think the economic outlook should brighten, helped by both the monetary stimulus from the Federal Reserve and the fiscal stimulus from the major tax cut pushed through Congress by President Bush. We believe corporate bonds continue to have the potential to outperform governments, although their performance advantage is likely to be more moderate.

Organization and Significant Accounting Policies Pioneer Bond Fund (the Fund) is a Delaware business 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 Fund offers five classes of shares - Class A, Class B, Class C, Class R, and Class Y shares. Class R shares were first publicly offered April 1, 2003. Each class of shares represents an interest in the same portfolio of investments of the Fund and have equal rights to voting, redemptions, dividends and 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 has been adopted by Class A, Class B, Class C, and Class R shareowners, respectively. There is no distribution plan for Class Y shares. On September 28, 2001 (Closing Date), the Fund acquired the assets of the Pioneer Limited Maturity Bond Fund in exchange solely for (I) the issuance of Class A, Class B and Class Y shares of beneficial interest of the Fund and (II) the assumption by the Fund of the liabilities of the Pioneer Limited Maturity Bond Fund. Following this transfer, the Pioneer Limited Maturity Bond Fund was liquidated and dissolved and Class A, B, and Y shares of the Fund were distributed to the former shareowners of the Pioneer Limited Maturity Bond Fund. The reorganization was accomplished by a tax-free transfer of assets whereby each shareowner of the Pioneer Limited Maturity Bond Fund received a number of full and fractional shares of the Fund held as of the Closing Date. The unrealized appreciation of $707,251 at the date of transfer was treated as non-taxable by the Pioneer Limited Maturity Bond Fund. As such, the Pioneer Bond Fund's basis in the securities transferred reflects their historical cost basis as of the date of transfer. The portfolio turnover shown in the financial highlights excludes purchases and sales of securities by the Pioneer Limited Maturity Bond Fund prior to the date of transfer. The shares issued in connection with the acquisition are included in shares sold in the 32 Pioneer Bond Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- statement of changes in net assets. The net assets, net asset values per share and shares outstanding as of the Closing Date were: Limited Maturity Bond Fund (Pre-reorganization) - ---------------------------------------------------------------------------- Class A Class B Class Y - ---------------------------------------------------------------------------- Net Assets $ 25,353,014 $ 7,227,654 $ 463,902 Shares Outstanding 6,789,834 1,943,967 123,913 Net Asset Value Per Share 3.73 3.72 3.74 Bond Fund (Pre-reorganization) - ------------------------------------------------------------------------------------------- Class A Class B Class C Class Y - ------------------------------------------------------------------------------------------- Net Assets $ 105,362,478 $ 42,828,737 $ 9,521,769 $ 1,521,296 Shares Outstanding 11,875,065 4,831,398 1,079,669 171,511 Net Asset Value Per Share 8.87 8.86 8.82 8.87 Bond Fund (Post-reorganization) - ----------------------------------------------------------------------------------------- Class A Class B Class C Class Y - ----------------------------------------------------------------------------------------- Net Assets $ 130,715,492 $50,056,389 $9,521,769 $1,985,198 Shares Outstanding 14,732,532 5,646,730 1,079,669 223,811 Net Asset Value Per Share 8.87 8.86 8.82 8.87 33 Pioneer Bond Fund - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 6/30/03 (continued) - -------------------------------------------------------------------------------- The Fund's financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America 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 investment income, gains and expenses during the reporting periods. Actual results could differ from those estimates. The following is a summary of significant accounting policies consistently followed by the Fund. 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. Principal amounts of mortgage-backed securities are adjusted for monthly paydowns. All discounts/premiums are accreted/amortized for financial reporting purposes over the life of the respective securities. Premium and discount 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. Amortization and accretion of premium or discount on debt securities is included in interest income. 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 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. 34 Pioneer Bond Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- The characterization of distributions to shareowners for financial reporting purposes is determined in accordance with federal income tax rules. Therefore, the source 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. For the year ending June 30, 2003, the Fund reclassified $2,672,897 to decrease paid-in capital, $1,412,950 to increase accumulative undistributed net investment income, and $1,259,947 to decrease accumulated net realized loss on investments to reflect permanent book/tax differences. The reclassification has no impact on the net asset value of the Fund and presents the Fund's capital accounts on a tax basis. The tax character of distributions paid during the years ended June 30, 2003 and 2002 were as follows: - -------------------------------------------------------------- 2003 2002 - -------------------------------------------------------------- Distributions paid from: Ordinary income $13,122,468 $11,033,511 Long-term capital gain - - ----------- ----------- $13,122,468 $11,033,511 Return of capital - - ----------- ----------- Total $13,122,468 $11,033,511 =========== =========== The following shows components of distributable earnings on a federal income tax basis at June 30, 2003. - -------------------------------------------------------------- 2003 - -------------------------------------------------------------- Undistributed ordinary income $ 1,299,505 Capital loss carryforward (14,182,972) Undistributed long-term gain - Unrealized appreciation 17,649,956 ----------- Total $ 4,766,489 =========== 35 Pioneer Bond Fund - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 6/30/03 (continued) - -------------------------------------------------------------------------------- The difference between book-basis and tax-basis unrealized appreciation is attributable to the tax treatment of amortization and accretion on debt securities. 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 $55,081 in underwriting commissions on the sale of Fund shares for year ended June 30, 2003. 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 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 their 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 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, Class R and Class Y shares can bear different transfer agent and distribution fees. E. Repurchase Agreement With respect to purchase 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 36 Pioneer Bond Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- 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. Security 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 dividends on the securities loaned. Gain or loss in 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 fair value of 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 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 Pioneer Investment Management, Inc. (PIM), the Fund's investment adviser, manages the Fund'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 Fund's average daily net assets. In 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 June 30, 2003, $134,093 was payable to PIM related to management fees, administrative fees and certain other services and is included in due to affiliates. 37 Pioneer Bond Fund - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 6/30/03 (continued) - -------------------------------------------------------------------------------- 3.

Included in due to affiliates is $76,489 in transfer agent fees payable to PIMSS at June 30, 2003. 4. Distribution and Service Plans The Fund adopted a Plan of Distribution with respect to Class A, Class B, Class C and Class R Shares (Class A Plan, Class B Plan, Class C Plan and Class R Plan) in accordance with Rule 12b-1 under 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 $134,893 in distribution fees payable to PFD at June 30, 2003. 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 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 each class of 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%.

These financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audit. The Financial Highlights for each of the three years in the period ended June 30, 2001 were audited by other auditors who have ceased operations and whose report, dated August 10, 2001, expressed an unqualified opinion on those financial highlights. We conducted our audits in accordance with auditing standards generally accepted in the United States. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements and financial highlights. Our procedures included confirmation of securities as of June 30, 2003, by correspondence with the custodian and brokers or by other appropriate auditing procedures whose replies from brokers were not received. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provides a reasonable basis for our opinion. In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of Pioneer Bond Fund at June 30, 2003, and the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the periods indicated in the two years then ended in conformity with accounting principles generally accepted in the United States. /s/ Ernst & Young LLP Boston, Massachusetts August 13, 2003 40 Pioneer Bond Fund - -------------------------------------------------------------------------------- TRUSTEES, OFFICERS AND SERVICE PROVIDERS - -------------------------------------------------------------------------------- Investment Adviser Pioneer Investment Management, Inc.
