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 participated in the recent rally, 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. 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 becomes a candidate 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. The preceding information is the opinion of fund management. Past performance is no guarantee of future results, and there is no guarantee that market forecasts discussed will be realized. - -------------------------------------------------------------------------------- Pioneer's new president Osbert Hood was recently named Chief Executive Officer and President of Pioneer Investments USA. 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." - -------------------------------------------------------------------------------- 1 Pioneer Balanced Fund PORTFOLIO SUMMARY 6/30/03 Portfolio Diversification - -------------------------------------------------------------------------------- (As a percentage of total investment portfolio) [THE FOLLOWING WAS REPRESENTED AS A PIE CHART IN THE PRINTED MATERIAL] U.S. Common Stocks 60.0% U.S. Corporate Bonds 19.9% U.S. Government Securities 17.5% Temporary Cash Investment 2.2% Foreign Government Bond 0.4% Sector Distribution - -------------------------------------------------------------------------------- (As a percentage of total long-term securities) Government Obligations 18.3% Consumer Staples 17.7% Financials 12.2% Consumer Discretionary 11.0% Information Technology 10.6% Health Care 9.4% Energy 7.4% Industrials 6.1% Materials 4.8% Utilities 2.3% Telecommunication Services 0.2% 10 Largest Holdings - -------------------------------------------------------------------------------- (As a percentage of total long-term securities) 1.

In this improving environment, both the equity and fixed-income portions of Pioneer Balanced Fund's portfolio delivered strong results. In the following interview, Timothy Mulrenan, who is responsible for the Fund's equity portfolio, and Richard Schlanger, who oversees the fixed-income portfolio, discuss the markets and their investment strategies during the past six months. Q: How did the Fund perform during the six-month period? A: The Fund performed very well. For the six months ended June 30, 2003, Pioneer Balanced Fund's Class A shares had a total return of 8.59%. During the same period, Class B and Class C shares had returns of 8.05% and 8.11%, respectively. All returns are at net asset value. Q: How would you describe the investment environment? A: After it became apparent in early March that the significant fighting in Iraq would end quickly, market sentiment improved rapidly and investors became willing to allocate funds to riskier sectors in virtually all asset classes in pursuit of greater returns. Optimism rose because of military success in Iraq and the anticipation that the economy would begin to rebound because of the effects of both new tax cuts and the Federal Reserve Board's policies to cut short-term interest rates to stimulate growth. In the equity markets, performance was led by stocks from those industries that had been in the most disfavor during the previous three years, including technology, biotechnology and Internet stocks, as well as small-cap stocks in general. In the fixed-income markets, interest rates fell across the spectrum of maturities, with longer-maturity securities posting the strongest total returns. Corporate bonds, especially lower-rated bonds, outperformed government securities as investors anticipated improving credit quality in an economic revival. 6 Pioneer Balanced Fund Q: Did you make any changes to your asset allocation during the period? A: Yes. We increased our stock weighting. We began the period with a target allocation of 55% equities, 45% fixed income. However, in March we increased the target allocation for stocks to 60% and lowered the fixed-income allocation to 40%. On a relative value basis, equities looked much more attractive to us. This proved to be a timely decision during a period of rapidly rising stock prices. Q: What were your principal fixed-income strategies? A: We pared back our smaller positions and added to our positions of those securities in which we had the greatest confidence. During a period when many new corporate bonds were issued, we took advantage of this supply and sold some of our shorter-term corporate securities while selectively adding longer-maturity corporates, especially when we saw strong relative values. Within our corporate holdings, we lightened our exposure to banks because we were concerned that the profit margins from their traditional lending business were likely to shrink as the difference between long-term and short-term rates narrowed. We continued to underweight government securities due to supply considerations and an expanding deficit. We reduced our holdings of mortgage-backed securities because of our concerns about prepayment risk, as homeowners refinanced their mortgages. On June 30, 30.8% of the Fund's fixed-income assets were invested in mortgage securities, compared with 50.4% on December 31, 2002. Overall, industrial and utility bonds accounted for 36.8% of fixed-income assets, including 7.8% in high-yield bonds. Bank and finance comprised 13.5%, while government and agencies accounted for 13.9%. About 5% of fixed-income assets were invested in temporary cash investments. The average credit quality of the Fund's portfolio was rated A and the effective duration of the portfolio was 4.26 years, compared with 3.42 years on December 31, 2002. (Ratings apply to underlying securities, not Fund shares.) Our corporate bond holdings were the best performing investments, with our high yield positions turning in particularly impressive results. 7 Pioneer Balanced Fund PORTFOLIO MANAGEMENT DISCUSSION 6/30/03 (continued) Q: What were your principal equity strategies? A: In general, we focused on large-cap, better quality, stable-growth companies, while reducing our exposure to financial stocks and technology stocks because of our concern about the risks in those sectors. Progressive Corp., the well-known automobile-insurance company, was the single best-performing stock during the six months. Progressive has increased its market share by competing successfully in all three distribution channels for automobile insurance - agents, direct sales and the Internet. In addition, it was one of the earliest companies to perceive a change in the industry's pricing power. As a result, it raised its premiums before many of its competitors. Now, the company is enjoying the benefits of higher premiums while competitors are raising their premiums to their customers' displeasure. After we added pharmaceutical company Wyeth to the portfolio in April, the company's stock rallied based on strong drug sales and its decision to use proceeds from its sale of Amgen stock to buy down its debt and improve its balance sheet. Family Dollar, a well managed national discount retail chain, continued to post strong results from sales both in existing and new store locations. Progressive, Wyeth and Family Dollar together make up more than 14% of the equity portfolio, and their strong performances had a major influence on Fund results. Defense contractor Northrop Grumman was the portfolio's weakest performer over the six months with a decline of 10%. The rising federal deficit is causing some concern that future defense spending may be curtailed. However, as long as the threat of domestic terrorism continues and global geopolitical risks remain high we believe that public support for defense spending will also remain high. Berkshire Hathaway was flat in the period. Most stocks in the insurance sector were weak due to heightened concerns about pricing and profitability in the property and casualty insurance market. We believe Berkshire is the premier underwriter in the insurance sector and we think it will continue to capture market share from weaker competitors. 8 Pioneer Balanced Fund Q: What is your outlook for fixed-income investments? A: We think the economy will grow, but at a slower pace than in many past recoveries, in part because energy prices remain high. We estimate the national gross domestic product (GDP) will grow at an annualized rate of less than 4% during the second half of 2003. Because of high unemployment and unused industrial capacity, it is possible that the Federal Reserve may lower rates again. However, we believe the Fed is unlikely to raise rates before the second half of 2004. With this outlook, we think corporate bonds and mortgages are likely to outperform government securities in the coming months. Longer term, we are concerned about the effects of rising federal deficits and the corporate profit outlook, particularly if revenue-strapped states start raising corporate taxes, which could limit business investment. Q: What is your outlook for equity investments? A: After the strong rally of the first six months of 2003, we think the market may pause and stock prices may remain within a trading range. Many stock prices currently are priced based on very optimistic expectations for corporate profit growth. Thus far, much of the gains in corporate profitability have been derived from cost cuts rather than revenue gains. We believe that in order for stock prices to go higher, we will need more evidence of a sustained economic recovery than we have seen. The preceding information is the opinion of fund management. Past performance is no guarantee of future results, and there is no guarantee that market forecasts discussed will be realized. 9 Pioneer Balanced Fund SCHEDULE OF INVESTMENTS 6/30/03 (unaudited) Shares Value COMMON STOCKS - 60.0% Energy - 6.0% Integrated Oil & Gas - 0.6% 23,100 Exxon Mobil Corp. $ 829,521 ------------ Oil & Gas Drilling - 3.9% 26,000 Encana Corp. $ 997,620 87,100 ENSCO International, Inc. 2,342,990 81,400 Varco International, Inc. * 1,595,440 ------------ $ 4,936,050 ------------ Oil & Gas Exploration & Production - 1.5% 36,376 Devon Energy Corp. $ 1,942,478 ------------ Total Energy $ 7,708,049 ------------ Materials - 2.8% Precious Metals & Minerals - 2.8% 108,400 Newmont Mining Corp. $ 3,518,664 ------------ Total Materials $ 3,518,664 ------------ Capital Goods - 3.2% Aerospace & Defense - 2.5% 37,300 Northrop Grumman Corp. $ 3,218,617 ------------ Electrical Components & Equipment - 0.7% 38,500 Molex, Inc. $ 892,392 ------------ Total Capital Goods $ 4,111,009 ------------ Commercial Services & Supplies - 0.5% Diversified Commercial Services - 0.5% 18,700 Cintas Corp. $ 662,728 ------------ Total Commercial Services & Supplies $ 662,728 ------------ Transportation - 1.1% Trucking - 1.1% 21,200 United Parcel Service $ 1,350,440 ------------ Total Transportation $ 1,350,440 ------------ Consumer Durables & Apparel - 0.5% Leisure Products - 0.5% 15,300 Harley-Davidson, Inc. $ 609,858 ------------ Total Consumer Durables & Apparel $ 609,858 ------------ 10 The accompanying notes are an integral part of these financial statements.

The accompanying notes are an integral part of these financial statements. 27 Pioneer Balanced Fund NOTES TO FINANCIAL STATEMENTS 6/30/03 (unaudited) 1. Organization and Significant Accounting Policies Pioneer Balanced 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 Fund's investment objective is to seek capital growth and current income. The Fund offers three classes of shares - Class A, Class B and Class C shares. Shares of each class represent 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 distribution fees and has exclusive voting rights with respect to the distribution plans that have been adopted by Class A, Class B and Class C shareowners, respectively. 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 revenues 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, which are in conformity with those generally accepted in the investment company industry: A. Security Valuation Security transactions are recorded as of trade date. The net asset value is computed once daily, on each day the New York Stock Exchange is open, as of the close of regular trading on the Exchange. In computing the net asset value, debt securities are valued at prices supplied by independent pricing services, which consider such factors as Treasury spreads, yields, maturities and ratings. All discounts/premiums are accreted/amortized for financial reporting purposes. Valuations may be supplemented by dealers and other sources, as required. Equity securities are valued at the last sale price on the principal exchange where they are traded. Securities that have not traded on the date of valuation, or securities for which sale prices are not generally reported, are valued at 28 Pioneer Balanced Fund the mean between the last bid and asked prices. Securities for which market quotations are not readily available are valued at their fair values as determined by, or under the direction of, the Board of Trustees. Dividend income is recorded on the ex-dividend date except that certain dividends from foreign securities where the ex-dividend date may have passed are recorded as soon as the Fund is informed of the ex-dividend data in exercise of reasonable diligence. Interest income, including interest on income bearing cash accounts, 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. Futures Contracts The Fund may enter into futures transactions to hedge against changes in interest rates, securities prices, and currency rates or to seek to increase total return. Upon entering into a futures contract, the Fund is required to deposit with a broker an amount of cash or securities equal to the minimum "initial margin" requirements of the associated futures exchange. Subsequent payments for futures contracts ("variation margin") are paid or received by the Fund, depending on the daily fluctuation in the value of the contracts, and are recorded by the Fund as unrealized gains or losses. When the contract is closed, the Fund realizes a gain or loss equal to the difference between the opening and closing value of the contract. The use of futures contracts involves, to varying degrees, elements of market risk which may exceed the amounts recognized by the Fund. Changes in the value of the contracts may not directly correlate to the changes in the value of the underlying securities. These risks may decrease the effectiveness of the Fund's hedging and trading strategies and potentially result in a loss. As of June 30, 2003, the Fund had no open futures contracts. 29 Pioneer Balanced Fund NOTES TO FINANCIAL STATEMENTS 6/30/03 (unaudited) (continued) C. 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 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. 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, 2002 was as follows: 2002 ---------- Distributions paid from: Ordinary income $1,646,107 Long-term capital gain -- ---------- Total $1,646,107 ---------- The following shows components of distributable earnings on a federal income tax basis at December 31, 2002. These amounts do not include the capital loss carryforward. 2002 --------- Undistributed ordinary income $ 49,004 Undistributed long-term gain -- Unrealized depreciation (759,684) --------- Total $(710,680) --------- The difference between book-basis and tax-basis unrealized depreciation is primarily attributable to the tax deferral of losses on wash sales and the tax treatment of premuim amortization. 30 Pioneer Balanced Fund D. 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 $8,414 in underwriting commissions on the sale of Fund shares during the six months ended June 30, 2003. E. Class Allocations Distribution fees are calculated based on the average daily net asset value attributable to Class A, Class B and Class C shares of the Fund, 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 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. 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 and Class C shares can bear different transfer agent and distribution fees. F. Repurchase Agreements With respect to repurchase agreements entered into by the Fund, the value of the underlying securities (collateral), including accrued interest received from 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. 31 Pioneer Balanced Fund NOTES TO FINANCIAL STATEMENTS 6/30/03 (unaudited) (continued) 2. Management Agreement PIM, the Fund's investment adviser and a wholly owned indirect subsidiary of UniCredito Italiano, manages the Fund's portfolio. Management fees are calculated daily at the annual rate of 0.65% of the Fund's average daily net assets up to $1 billion; 0.60% of the next $4 billion; and 0.55% of the excess over $5 billion. 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, $76,685 was payable to PIM related to management fees, administrative fees and certain other services. 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 $14,355 in transfer agent fees payable to PIMSS at June 30, 2003. 4. Distribution Plans The Fund adopted a Plan of Distribution for each class of shares (Class A Plan, Class B Plan and Class C 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. Included in due to affiliates is $42,727 in distribution fees payable to PFD at June 30, 2003. 32 Pioneer Balanced Fund 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%. Proceeds from the CDSCs are paid to PFD. For the six months ended June 30, 2003, CDSCs in the amount of $17,594 were paid to PFD. 5. Expense Offsets The Fund has entered into certain expense offset arrangements resulting in a reduction in the Fund's total expenses. For the six months ended June 30, 2003, the Fund's expenses were reduced by $1,819 under such arrangements. 6. Line of Credit Facility The Fund, along with certain other funds in the Pioneer Family of Funds (the Funds), collectively participate in a $50 million committed, unsecured revolving line of credit facility. Borrowings are used solely for temporary or emergency purposes. The Fund may borrow up to the lesser of $50 million or the limits set by its prospectus for borrowings. Interest on collective borrowings is payable at the Federal Funds Rate plus 1/2% on an annualized basis. The Funds pay an annual commitment fee for this facility. The commitment fee is allocated among such Funds based on their respective borrowing limits. For the six months ended June 30, 2003, the Fund had no borrowings under this agreement. 33 Pioneer Balanced Fund TRUSTEES, OFFICERS AND SERVICE PROVIDERS Trustees Officers John F.
