Job conditions are strengthening as well: by mid-year, the unemployment rate had fallen to 5.0% for the first time since September 11, 2001. Retail sales trends - - apart from automobiles - were upbeat as sunnier employment prospects sent consumers to the malls. And with the economy expanding, corporate profits have been moving ahead smartly. But equity investors were unconvinced by this evidence and instead brooded about the possibility of slowing growth later in the year. For one thing, expectations were for a moderating pace of profit growth. For another, the Federal Reserve Board has raised short-term interest rates nine times. And some areas of the economy are feeling the impact of record high energy prices. So investors were lukewarm toward stocks, with modest losses in the S&P 500 Stock Index and the Dow Jones Industrials the result. The technology-heavy NASDAQ Composite also slid, as did small-company stocks, as measured by the Russell 2000 Index. Value stocks, viewed as less vulnerable to declines in a less robust economy, held up better than growth. Corporate bonds felt the sting of ratings downgrades in the automobile sector. Treasury issues fared better, as yields fell and prices rose among intermediate and longer-term issues, which were little affected by rising short-term rates. Low long-term yields may signal investor confidence that the Fed will succeed in dousing inflationary fires; they also brought more affordable mortgages, further boosting home construction. Municipal revenue bonds edged upward as healthier economic conditions bolstered tax collections. The dollar's rebound positively affected foreign markets. Europe's stock markets performed better than business and political conditions might suggest, and Japan's market inched higher. Pioneer's analysts believe that, although the rate of growth may slow, carefully selected, good quality stocks and bonds have the potential to deliver solid results. Our global investment experts are well positioned to discover what we believe are attractive opportunities in the world's markets. Large or small? Bonds or stocks? Domestic or international? Just what your mix of investments should be isn't a question to be taken lightly. Much of your long-term return will depend on the kinds of investments you own, not just the individual items in your portfolio.

The performance of Class R shares for the period prior to the commencement of operations of Class R shares on April 1, 2003 is based on the performance of Class A shares, reduced to reflect the higher distribution and service fees of Class R shares. For the period after April 1, 2003, the actual performance of Class R shares is reflected, which performance may be influenced by the smaller asset size of Class R shares compared to Class A shares. Class R shares are not subject to sales charges and are available for limited groups of eligible investors, including institutional investors.

This example is intended to help you understand your ongoing expenses (in dollars) of investing in the Trust 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 Trust'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 [divided by] $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 America Income Trust Based on actual returns from January 1, 2005 through June 30, 2005 Investor Share Class A B C Class R - --------------------------------------------------------------------------------------------- Beginning Account Value $1,000.00 $1,000.00 $1,000.00 $1,000.00 $1,000.00 On 1/1/05 Ending Account Value $1,020.00 $1,014.80 $1,015.50 $1,021.00 $1,018.80 On 6/30/05 Expenses Paid During $ 5.91 $ 10.09 $ 9.44 $ 3.76 $ 6.36 Period* * Expenses are equal to the Trust's annualized expense ratio of 1.18%, 2.02%, 1.89%, 0.75% and 1.27%, for Class A, Class B, Class C, Investor Class and Class R shares, respectively, multiplied by the average account value over the period, multiplied by 181/365 (to reflect the one-half year period). 9 Pioneer America Income Trust - -------------------------------------------------------------------------------- COMPARING ONGOING FUND EXPENSES (continued) - -------------------------------------------------------------------------------- Hypothetical Example for Comparison Purposes The table below provides information about hypothetical account values and hypothetical expenses based on the Trust's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Trust'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 Trust 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) that are charged at the time of the transaction. 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 America Income Trust Based on a hypothetical 5% per year return before expenses, reflecting the period from January 1, 2005 through June 30, 2005 Investor Share Class A B C Class R - --------------------------------------------------------------------------------------------- Beginning Account Value $1,000.00 $1,000.00 $1,000.00 $1,000.00 $1,000.00 On 1/1/05 Ending Account Value $1,078.94 $1,014.78 $1,015.42 $1,021.08 $1,018.50 On 6/30/05 Expenses Paid During $ 5.91 $ 10.09 $ 9.44 $ 3.76 $ 6.36 Period* * Expenses are equal to the Trust's annualized expense ratio of 1.18%, 2.02%, 1.89%, 0.75% and 1.27%, for Class A, Class B, Class C, Investor Class and Class R shares, respectively, multiplied by the average account value over the period, multiplied by 181/365 (to reflect the one-half year period). 10 Pioneer America Income Trust - -------------------------------------------------------------------------------- PORTFOLIO MANAGEMENT DISCUSSION 6/30/05 - -------------------------------------------------------------------------------- Despite rising interest-rates, investors in U.S. Government and agency securities were rewarded with positive total returns during the first half of 2005. 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 period? A: For the six-month period ended June 30, 2005, Class A shares of Pioneer America Income Trust produced a total return of 2.00% at net asset value. The Trust underperformed its benchmark, the Lehman Brothers Government Bond Index, which returned 2.93% for the same period. The Trust also fell short of the Lehman Brothers Fixed-Rate Mortgage-Backed Index, which returned 2.15%. The Trust underperformed the 2.74% 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 3.08%. Call 1-800-225-6292 or visit www.pioneerfunds.com for the most recent month-end performance results. Current performance may be lower or higher than the performance data quoted. 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 was the investment environment like during the period? A: Despite rising oil prices, the economy continued to grow at a steady pace, buoyed by job creation, a high level of consumer spending and escalating real estate prices. Along with this positive economic backdrop, the Federal Reserve continued to reverse its accommodative monetary policy by boosting the Federal funds rate four times during the six-month period, each time by one-quarter percentage point. The Federal funds rate, which is the rate that banks charge for overnight loans, moved from 2.25% to 3.25%. The Fed's actions resulted in rising yields and falling prices on short-term securities; however, yields on longer-term securities declined and prices rose. For example, the yield on the 10-year Treasury bond declined 0.31% and the yield on the 30-year Treasury bond went down 0.64%. Despite the general decline in long-term yields, long-term U.S. Treasury yields were among the highest of the developed economies, making the securities attrac- 11 Pioneer America Income Trust - -------------------------------------------------------------------------------- PORTFOLIO MANAGEMENT DISCUSSION 6/30/05 (continued) - -------------------------------------------------------------------------------- tive to foreign investors. U.S. Treasuries were favored by overseas investors for another reason. To keep their currency values relatively low, overseas market participants invested substantial assets in Treasury securities. During the period, General Motors and Ford reported disappointing earnings, and credit agencies downgraded the companies' debt. As a result, we saw a flight to quality in the fixed-income markets, with investors moving assets into Treasury securities because they had no credit risk and the full faith and credit backing of the U.S. Government. All of these factors benefited government bonds. Q: What were the principal strategies used in managing the Trust in this environment? A: While we trimmed exposure to mortgages issued by the Government National Mortgage Association (Ginnie Mae), we continued to emphasize the sector relative to the benchmark. Ginnie Maes 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.) In selecting mortgage securities, we emphasized those with coupons in the 4.5% to 5.0% range, which carried less prepayment risk. When interest rates rose and yields on Treasuries moved higher, we opportunistically purchased longer-duration Treasury securities in the 7 to 15-year maturity range. At the end of the six-month period, the Trust's assets were allocated as follows: 67.5% in Ginnie Mae securities; 31.5% in Treasury securities; and 1% in cash. Q: What detracted from performance? A: We attribute the Trust's performance shortfall relative to the Lehman Brothers Fixed-Rate Mortgage Index to the defensive nature of our duration strategy. To limit the price volatility that usually accompanies rising interest rates, we kept the Trust's duration shorter than the index. (Stated in years, duration measures a bond's price sensitivity to interest-rate changes. A shorter duration can protect the portfolio from price declines as yields rise.) Performance also suffered because of our relatively small exposure to long-term Treasury bonds, as we were skeptical that prices would continue to rise as the Fed continued to raise interest rates. Even Federal Reserve Chairman Alan Greenspan called the rally in long-term Treasuries a "conundrum." Ginnie Maes also had a negative impact on performance because the decline in long-term Treasury 12 Pioneer America Income Trust - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- yields raised concerns about the potential for refinance risk that is associated with mortgages. Q: What contributed most to performance? A: Although we had comparatively less exposure (relative to the Fund's benchmark) in long-term Treasuries, our position in the sector and in Ginnie Mae securities contributed to performance, as both asset classes saw an influx of foreign capital. Minimizing prepayment risk by selecting specific mortgage pools was also helpful. Q: What is your outlook for the rest of 2005? A: Data associated with the economy continues to indicate that economic growth will keep improving at a steady rate, despite the fact that oil has now passed the $60-a-barrel level. Although inflation remains in check, there are indications that it is beginning to pick up. For example, rising global demand for commodities and industrial products has resulted in higher prices. We have also begun to see an upturn in airline, railroad and trucking prices, as companies pass along the cost of energy to consumers and businesses. Escalating real estate values are also a source of concern. Given these factors, the Fed has stated that it will continue raising interest rates in the near term in an effort to keep inflation from accelerating. As the Fed hikes rates, we expect to see longer-term yields drift higher. As we move into the second half of 2005, the Trust should continue to provide a relatively safe haven for investors who want to avoid the risk associated with the more volatile areas of the fixed-income market and with equities. Government guarantees apply to the underlying securities only and not to the prices and yields of the portfolio. When interest rates rise, the prices of fixed-income securities in the Trust will generally fall. Conversely, when interest rates fall the prices of fixed-income securities in the Trust 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 Trust are subject to possible loss due to the financial failure of underlying securities and their inability to meet their debt obligations. These risks may increase share price volatility. 13 Pioneer America Income Trust - -------------------------------------------------------------------------------- PORTFOLIO MANAGEMENT DISCUSSION 6/30/05 (continued) - -------------------------------------------------------------------------------- Any information in this shareholder report regarding market or economic trends or the factors influencing the Trust's historical or future performance are statements of the opinion of Trust management as of the date of this report.

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 Trustees have authorized the issuance of five classes of shares of the Fund. The Fund offers five classes of shares designated as - Class A, Class B, Class C, Investor Class and Class R shares. Class R shares were first publicly offered on April 1, 2003. Investor Class shares were first issued 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 Trust and have equal rights to voting, redemptions, dividends and liquidation, except that each class of shares can bear different transfer agent and distribution fees and has exclusive voting rights with respect to the distribution plans that have been adopted by Class A, Class B, Class C and Class R shareowners, respectively. There is no distribution plan for Investor Class shares. 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 year. Actual results could differ from those estimates. The following is a summary of significant accounting policies followed by the Trust 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. The net asset value of the Trust is computed once daily on each day the New York Stock Exchange (NYSE) is open, as of the close of regular trading on the NYSE. In computing the net asset value, securities are valued at prices supplied by independent pricing services, 36 Pioneer America Income Trust - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- 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 market quotations are not readily available are valued at their fair values as determined by, or under the direction of the Board of Trustees. Securities for which there are no other readily available valuation methods are valued at their fair values as determined by, or under the direction of the Board of Trustees. As of June 30, 2005, there were no securities fair valued. Principal amounts of mortgage-backed securities are adjusted for monthly paydowns. Premiums and discounts related to certain mortgage-backed securities are amortized or accreted in proportion to the underlying monthly pay downs. All discounts/premiums on debt securities are accreted/amortized into interest income on a yield to maturity basis 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 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 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. At December 31, 2004, the Trust had a net capital loss carryforward of $10,221,165, of which $742,335 will expire in 2006, $2,705,283 will expire in 2007, $1,526,846 will expire in 2008, $2,070,786 will expire in 2011 and $3,175,915 will expire in 2012 if not utilized. 37 Pioneer America Income Trust - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 6/30/05 (unaudited) (continued) - -------------------------------------------------------------------------------- The Trust has elected to defer approximately $261,212 of capital losses recognized between November 1, 2004 and December 31, 2004 to its fiscal year ended December 31, 2005. The tax character of current year distributions will be determined at the end of the fiscal year. The tax character of distributions paid during the year ended December 31, 2004 was as follows: - -------------------------------------------------------------------------------- 2004 - -------------------------------------------------------------------------------- Distributions paid from: Ordinary income $8,808,385 Long-term capital gain - ---------- $8,808,385 Return of Capital - ---------- Total $8,808,385 ========== - -------------------------------------------------------------------------------- The following shows the components of accumulated losses on a federal income tax basis at December 31, 2004. - -------------------------------------------------------------------------------- 2004 - -------------------------------------------------------------------------------- Undistributed ordinary income $ 116,233 Capital loss carryforward (10,221,165) Post October losses deferred (261,212) Unrealized appreciation 191,113 ------------ Total $(10,175,031) ============ - -------------------------------------------------------------------------------- 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 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 $11,841 in underwriting commissions on the sale of Class A shares for the period ended June 30, 2005. 38 Pioneer America Income Trust - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- 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 (See Notes 4). 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 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, Investor Class and Class R shares can bear different transfer agent and distribution fees. E. Repurchase Agreements With respect to repurchase agreements entered into by the Trust, the value of the underlying securities (collateral), including accrued interest received from counter parties, is required to be at least equal to or in excess of the value of the repurchase agreement at the time of purchase. The collateral for all repurchase agreements is held in safekeeping in the customer-only account of the Trust's custodian, or sub custodians. The Trust's investment adviser, Pioneer Investment Management, Inc. (PIM), is responsible for determining that the value of the collateral remains at least equal to the repurchase price. 2. Management Agreement PIM, a wholly owned indirect subsidiary of UniCredito Italiano, manages the Trust's portfolio. Management fees are calculated daily at the annual rate of 0.50% of the Trust's average daily net assets. 39 Pioneer America Income Trust - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 6/30/05 (unaudited) (continued) - -------------------------------------------------------------------------------- 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. 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, 2005, $3,400 was payable to PIM related to management fees, administrative costs 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 $124,683 in transfer agent fees payable to PIMSS at June 30, 2005. 4. Distribution and Service Plans The Trust adopted Plans of Distribution with respect to each class of shares (Class A Plan, Class B Plan, Class C Plan, and Class R Plan) in accordance with Rule 12b-1 of the Investment Company Act of 1940. Pursuant to the Class A Plan, the Trust pays PFD a service fee of up to 0.25% of the Trust's average daily net assets attributable to Class A shares in reimbursement of such expenditures to finance activities primarily intended to result in the sale of Class A shares. Pursuant to the Class B Plan and the Class C Plan, the Trust pays PFD 1.00% of the average daily net assets attributable to each class of shares. The fee consists of a 0.25% service fee and a 0.75% distribution fee paid as compensation for personal services and/or account maintenance services or distribution services with regard to Class B and Class C shares. Pursuant to the Class R Plan, the Trust pays PFD 0.50% of the average daily net assets attributable to Class R shares for distribution services. Included in due to affiliates is $2,688 in distribution fees payable to PFD at June 30, 2005. 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 40 Pioneer America Income Trust - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- holding shares of the Trust a service fee of up to 0.25% of the Trust's daily net assets attributable to Class R shares held by such plans. In addition, redemptions of each class of shares (except Investor Class) 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). Class B shares subscribed on or after December 1, 2004 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%. Redemption 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 June 30, 2005, CDSCs in the amount of $51,156 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, 2005, the Trust's expenses were reduced by $5,055 under such arrangements. 6. Merger Information On December 8, 2004, beneficial owners of Safeco Intermediate Term U.S. Government Fund (one of the Series that comprised Safeco Managed Bond Trust) approved a proposed Agreement and Plan of Reorganization that provided for the merger below. This tax-free reorganization was accomplished on December 10, 2004, by exchanging all of Safeco's net assets for Investor Class shares, based on the Fund's Class A shares' ending net asset value. The following charts show the details of the reorganizations as of that closing date ("Closing Date"): 41 Pioneer America Income Trust - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 6/30/05 (unaudited) (continued) - -------------------------------------------------------------------------------- - ------------------------------------------------------------------------------------------------- Pioneer Safeco Pioneer America Intermediate Term America Income Trust U.S. Government Fund Income Trust (Pre-Reorganization) (Pre-Reorganization) (Post-Reorganization) - ------------------------------------------------------------------------------------------------- Net Assets $193,756,225 $53,131,201 $246,867,456 Shares Outstanding 19,757,153 5,599,642 25,167,692 Investor Class Shares Issued 5,410,509 - ------------------------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- Unrealized Accumulated Appreciation Loss on on Closing Date Closing Date - -------------------------------------------------------------------------------- Safeco Intermediate Term U.S. Government Fund $33,133 $(1,399,442) - -------------------------------------------------------------------------------- 42 Pioneer America Income Trust - -------------------------------------------------------------------------------- FACTORS CONSIDERED BY THE INDEPENDENT TRUSTEES IN APPROVING THE MANAGEMENT CONTRACT - -------------------------------------------------------------------------------- The Investment Company Act of 1940 requires that both the Board of Trustees and a majority of the Independent Trustees (collectively "the Trustees") vote separately annually to approve the Fund's management contract (the "Management Contract"). The Trustees have determined that the terms of the Management Contract are fair and reasonable and that renewal of the contract will enable the Fund to receive quality investment advisory services at a cost deemed reasonable and in the best interests of the Fund and its shareholders. In making such determinations, the Independent Trustees relied upon the assistance of counsel to the Independent Trustees and counsel to the Fund. Throughout the year, the Independent Trustees regularly met in executive session separately from the Interested Trustees of the Fund and any officer of Pioneer Investment Management, Inc., the Fund's adviser (the "Investment Adviser"), or its affiliates. While the Trustees, including the Independent Trustees, act on all major matters relating to the Fund, a significant portion of the activities of the Board of Trustees (including certain of those described herein) is conducted through committees, the members of which are comprised exclusively of Independent Trustees. Such committee meetings are attended by officers of the Fund or the Investment Adviser to the extent requested by the members of the committee. In evaluating the Management Contract, the Trustees conducted a review that was specifically focused upon the renewal of the Management Contract, and relied upon their knowledge, resulting from their meetings throughout the year, of the Investment Adviser, its services and the Fund. Both in meetings specifically dedicated to renewal of the Management Contract and at other meetings during the course of the year, the Trustees, including the Independent Trustees, received materials relating to the Investment Adviser's investment and management services under the Management Contract. These materials included (i) information on the investment performance of the Fund, a peer group of funds and two indices, in each case selected by the Independent Trustees for this purpose, (ii) sales and redemption data in respect to the Fund, (iii) the general investment outlook in the markets in which the Fund invests, (iv) arrangements in respect of the distribution of the Fund's shares, (v) the procedures employed to determine the value of each of the Fund's assets, (vi) the Investment Adviser's management of the relationships with the Fund's unaffiliated service providers, (vii) the record of compliance with the 43 Pioneer America Income Trust - -------------------------------------------------------------------------------- FACTORS CONSIDERED BY THE INDEPENDENT TRUSTEES IN APPROVING THE MANAGEMENT CONTRACT (continued) - -------------------------------------------------------------------------------- Fund's investment policies and restrictions and with the Fund's Code of Ethics and the structure and responsibilities of the Investment Adviser's compliance department, (viii) the nature, cost and character of non-investment management services provided by the Investment Adviser and its affiliates and (ix) the disclosures included in the Fund's prospectuses and reports to shareholders. Specifically in connection with the Independent Trustees' review of the Management Contract, the Independent Trustees requested and the Investment Adviser provided additional information in order to evaluate the quality of the Investment Adviser's services and the reasonableness of the fee under the Management Contract. Among other items, this information included data or analyses of (1) investment performance for one and three years and life of the Fund periods for the Fund and a peer group selected by the Independent Trustees for this purpose, (2) management fees incurred by a peer group of funds selected by the Independent Trustees for this purpose, (3) the advisory fees of comparable portfolios of other clients of the Investment Adviser, (4) expense ratios for the Fund and a peer group of funds selected by the Independent Trustees for this purpose, (5) the overall organization of the Investment Adviser, (6) the Investment Adviser's financial results and condition, including its and certain of its affiliates profitability from services performed for the Fund, (7) transfer agency fees and administrative reimbursements paid to the Investment Adviser or affiliates, (8) investment management staffing, and (9) operating expenses paid to third parties. The Trustees also reviewed information regarding the potential for the Fund and the Investment Adviser to benefit from further economies of scale in the management of the Fund in light of reasonable growth expectations for the Fund and certain of the Fund's expenses that are not incurred as fees based on a percentage of net assets. The following summarizes matters considered by the Trustees in connection with their renewal of the Fund's Management Contract. The Trustees did not identify any single factor as all-important or controlling, and the summary does not detail all the matters that were considered. A. Ancillary Benefits to Shareholders. The Trustees considered the benefits to shareholders of investing in a Fund that is part of a large number of investment companies offering a variety of 44 Pioneer America Income Trust - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- investment disciplines and providing for a large variety of Fund and shareholder services. B. Compliance and Investment Performance. The Trustees determined that the Investment Adviser had policies and systems reasonably designed to achieve compliance with the Fund's investment objectives and regulatory requirements. The Trustees also reviewed the Fund's investment performance based upon total return and yield, as well as the Fund's performance compared to both the performance of a peer group and an index, in each case selected by the Independent Trustees for this purpose. The Fund's performance based upon total return was in the third quintile of the peer group for the 12 months ended June 30, 2004, the fifth quintile for the three years ended June 30, 2004, and was in the fourth quintile for the five years ended June 30, 2004. (In all quintile rankings referred to throughout this discussion first quintile is most favorable to the Fund's shareholders. Thus, highest relative performance would be first quintile and lowest relative expenses also would be first quintile.) The Trustees also considered the yield on the Fund relative to the yield on the Lehman Brothers Government Bond Index. The Trustees noted that the Fund's policy of only investing in investments backed by the full faith and credit of the U.S. Treasury had a negative impact on performance relative to mutual funds in the peer group that can invest in a broader range of U.S. Government Securities. The Trustees concluded that, given the improving trend in performance, the performance of the Fund supported the continuation of the Management Contract. C. The Investment Adviser's Personnel and Methods. The Trustees reviewed the background of members of the team responsible for the daily management of the Fund and the Fund's investment objective and discipline. The Independent Trustees also have had discussions with senior management of the Investment Adviser responsible for investment operations and the senior management of the Investment Adviser's fixed income group. Among other things, the Trustees considered the number, education and experience of the Investment Adviser's investment staff and their use of technology and emphasis on analytics in view of the risk profile of securities in which the Fund invests. The Trustees concluded that the Investment Adviser had the quality and depth of personnel and 45 Pioneer America Income Trust - -------------------------------------------------------------------------------- FACTORS CONSIDERED BY THE INDEPENDENT TRUSTEES IN APPROVING THE MANAGEMENT CONTRACT (continued) - -------------------------------------------------------------------------------- the well-developed methods essential to performing its duties under the Management Contract. D. Nature and Quality of Other Services. The Trustees considered the nature, quality, cost and extent of other services provided to shareholders of the Fund, including administrative and shareholder services performed by the Investment Adviser under the Management Contract. The Trustees also considered the reasonableness of the arrangements for reimbursement of the Investment Adviser's out-of-pocket costs and expenses, including overhead, for certain administrative services that the Investment Adviser is not required to provide under the Management Contract. The Trustees also considered the nature and extent of the other services provided by the Investment Adviser's affiliates under other contracts and its supervision of third party service providers. Based on these considerations, the Trustees concluded that the nature, quality, cost and extent of such services are satisfactory and reliable and serve the shareholders of the Fund well. E. Management Fee and Expenses. The Trustees considered the Investment Adviser's fee under the Management Contract relative to the management fees charged by a peer group of funds selected by the Independent Trustees for this purpose using data provided by an independent third party. The Fund's management fee for the 12 months ended June 30, 2004 was in the third quintile relative to the management fees paid by the other funds in that peer group for the comparable period. The Trustees determined that the fee under the Management Contract was reasonable and fair in light of both the overall nature and quality of services provided by the Investment Adviser and the fees charged by the funds in the peer group. The Trustees also considered the Fund's expense ratio and expense ratios of a peer group of funds selected by the Independent Trustees for this purpose. The Fund's expense ratio for the 12 months ended June 30, 2004 was in the fourth quintile of the applicable peer group for the most recent fiscal year of the peer group for the comparable period. The Trustees concluded that the Fund's overall expense ratio was acceptable compared to comparably sized funds. F. Profitability. The Trustees considered the level of the Investment Adviser's profits with respect to the management of the Pioneer Funds, including details with respect to the Fund. This consideration 46 Pioneer America Income Trust - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- included a review of the Investment Adviser's methodology in allocating certain of its costs to the management of each Fund. The Trustees also considered the financial results realized by the Investment Adviser in connection with the operation of the Fund. They further considered the profits realized by the Investment Adviser and its affiliates from non-fund businesses that may benefit from or be related to the Fund's business. The Trustees considered the Investment Adviser's profit margins in comparison with the limited available industry data. The Trustees concluded that the Investment Adviser's profits from management of the Pioneer Funds, including the financial results derived from the Fund, bear a reasonable relationship to the services rendered and are fair for the management of the Fund. G. Economies of Scale. The Trustees considered the economies of scale with respect to the management of the Fund, whether the Fund had appropriately benefited from any economies of scale, and whether there is potential for realization of any further economies of scale. The Trustees concluded that, given current and anticipated asset levels, break points in the management fee were not necessary at this time. As assets increase, the Trustees will continue to evaluate annually the appropriateness of break points H. Other Benefits to the Investment Adviser. The Trustees also considered the character and amount of fees paid by the Fund, other than under the Management Contract, for services provided by the Investment Adviser and affiliates, including fees for services such as shareholder services. The Trustees also considered the receipt of sales loads and payments under Rule 12b-1 plans in respect to the Pioneer Funds (including the Fund). The Trustees further considered the revenues and profitability of the Investment Adviser's businesses other than the fund business, including the Investment Adviser's institutional investment advisory business. The Trustees considered the intangible benefits that accrue to the Investment Adviser and its affiliates by virtue of its relationship with the Fund and the Pioneer Funds as a group. The Trustees concluded that all these types of benefits accruing to the Investment Adviser were reasonable in the context of the overall relationship between the Investment Adviser and the Fund. 47 Pioneer America Income Trust - -------------------------------------------------------------------------------- FACTORS CONSIDERED BY THE INDEPENDENT TRUSTEES IN APPROVING THE MANAGEMENT CONTRACT (continued) - -------------------------------------------------------------------------------- Conclusion. The Trustees, in light of the Investment Adviser's overall performance, considered it appropriate to continue to retain the management services of the Investment Adviser. Based on their evaluation of all material factors deemed relevant and the advice of independent counsel, the Trustees concluded that the Management Contract with the Fund is fair and reasonable and voted to approve the continuation of the Management Contract for another year. 48 - -------------------------------------------------------------------------------- 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 recognize 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 recognize 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"), 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 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. 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. N/A (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.
