Mid-sized and small-cap indices scored modest gains, while indicators that track large-cap stocks showed even smaller changes. For bond investors, Treasury issues wound up the period with higher yields and lower prices than at year-end. The same was true of corporate issues, whose prices gave ground in the face of rising interest rates, while high-yield bonds, outstanding performers over recent quarters, also cooled off. Although the economic expansion continued to move ahead, investors were preoccupied with factors that might have undesirable impacts on the economy and the markets. For one thing, the threat of terrorism is never far from our minds. For another, the jump in oil prices, attributed to turmoil in the Mideast and vast demand from China and other developing nations, was a major factor. The cost of gas or oil for heating our homes, and gasoline for our cars is a critical component in household budgets. Industry, too, requires energy, and in many cases petroleum is an essential raw material. The "jobless" recovery became a job-generating machine for a few months, followed by a brief slump and a partial rebound. But strong boosts in employment quickly triggered fears of economic overheating; too much demand for goods and services, the reasons for aggressive corporate hiring, might trigger inflation. That would lead to higher interest rates that could choke off the recovery by causing consumers and businesses to hold back on outlays. In fact, on June 30, the Federal Reserve Board raised short-term interest rates by one-quarter percentage point, the first hike in four years. While there may be further increases, they probably will be gradual; the Federal Reserve Board would like to keep the expansion intact while keeping inflation at bay. And even after the Fed's June move, short-term rates remain near the lowest levels many of us have seen. U.S. businesses, which have done massive amounts of cost-cutting in recent years, can readily accommodate somewhat higher borrowing costs. In addition, the federal income tax cuts that have helped bolster growth over the past several quarters remain in place.

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 underperformed 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 7 Pioneer America Income Trust - -------------------------------------------------------------------------------- PORTFOLIO MANAGEMENT DISCUSSION 6/30/04 (continued) - -------------------------------------------------------------------------------- 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. 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 8 Pioneer America Income Trust - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- 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.

Pioneer America Income Trust - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 6/30/04 (unaudited) - -------------------------------------------------------------------------------- 1. 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. The Trust offers four classes of shares - Class A, Class B, Class C and Class R shares. Class R shares were first publicly offered on April 1, 2003. Shares of Class A, Class B, Class C and Class R 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. The Trust's financial statements have been prepared in conformity with U.S. generally accepted accounting principles that require the management of the Trust 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 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 board of Trustees. Principal amounts of mortgage-backed securities are adjusted for monthly paydowns. Premiums and discounts related to certain mortgage-backed securities are amortized or accreted in proportion to the underlying monthly pay downs. Securities for which there are no other readily available valuation methods are valued at their fair values as determined by, or 21 Pioneer America Income Trust - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 6/30/04 (unaudited) (continued) - -------------------------------------------------------------------------------- under the direction of the Board of Trustees. As of June 30, 2004, there were no securities fair valued. All discounts/premiums on debt securities are accreted/amortized for financial reporting purposes. Interest income is recorded on the accrual basis. Temporary cash investments are valued at amortized cost. 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 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 amount and characterization of distributions to shareowners for financial reporting purposes is determined in accordance with federal income tax rules. Therefore, the source of the Trust's distributions may be shown in the accompanying financial statements as either from 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, 2003 was as follows: - ----------------------------------------------------- 2003 - ----------------------------------------------------- Distributions paid from: Ordinary income $11,810,277 Long-term capital gain - ----------- $11,810,277 Return of Capital - ----------- Total $11,810,277 =========== - ----------------------------------------------------- The following shows the components of accumulated losses on a federal income tax basis at December 31, 2003. 22 Pioneer America Income Trust - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- - ----------------------------------------------------- 2003 - ----------------------------------------------------- Undistributed ordinary income $ - Capital loss carryforward (7,139,642) Post October losses deferred (516,281) Unrealized appreciation 1,052,239 ----------- Total $(6,603,684) =========== - ----------------------------------------------------- The difference between book basis and tax-basis unrealized appreciation is primarily attributable to the tax deferral of losses on wash sales and the tax treatment of premium and amortization. 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 $14,343 in underwriting commissions on the sale of Trust shares for the six 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 and Class R 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 3). 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 and Class R shares can bear different transfer agent and distribution fees. 23 Pioneer America Income Trust - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 6/30/04 (unaudited) (continued) - -------------------------------------------------------------------------------- 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. 2. 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, $98,414 was payable to PIM related to management fees, administrative fees and certain other services, and is included in due to affiliates. 3. 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. 4. Distribution and Service Plans The Fund adopted Plans of Distribution with respect to each class of shares (Class A Plan, Class B Plan, Class C Plan, and Class R Plan) 24 Pioneer America Income Trust - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- 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 Fund'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 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 six months ended June 30, 2003, CDSCs in the amount of $137,671 were paid to PFD. 5. 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 six months ended June 30, 2003, the Trust's expenses were reduced by $1,928 under such arrangements. 25 - -------------------------------------------------------------------------------- THE PIONEER FAMILY OF MUTUAL FUNDS - -------------------------------------------------------------------------------- Please consider a fund's investment objectives, risks, charges and expenses carefully before investing.

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.
