The war in Iraq continued, oil prices soared, then dropped, while short-term interest rates ratcheted steadily higher and intermediate and long-term rates stayed about the same. Natural disasters also threatened economic expansion. Still, the economy moved forward as corporate earnings grew. The hope of a growing economy was not reflected by the small gains or losses in the major U.S. market indices. Among capitalization ranges, midcap issues made the most headway. Bond prices held firm and yields remained low, perhaps a sign that the Federal Reserve Board's interest rate hikes would temper the inflationary pressures induced by a growing economy. Among the nagging issues facing the U.S. economy in 2006 is the potential impact of high energy prices on consumer spending and corporate profits. Also unknown at this time is whether the Federal Reserve Board will continue to raise interest rates under its new chairman, Ben Bernanke, who stated his top priority will be to maintain continuity. Rising interest rates and improving business conditions made U.S. holdings more attractive to foreign investors, helping to strengthen the dollar versus the euro and other key currencies. Investors in many foreign markets enjoyed stellar returns. Double-digit gains were widespread in Europe, Asia and Latin America. Even the long-dormant Japanese economy began to stir, while emerging markets, especially those rich in natural resources, fed global economic growth. The disparity of returns among countries and sectors underscores the importance for investors to maintain a well-diversified portfolio. We believe this may be a good time for investors to review their holdings with their advisor and determine if they reflect the wide range of opportunities that exist across many asset classes, as last year's results make clear.

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. The performance of Class R shares does not reflect the 1% CDSC that was in effect prior to July 1, 2004. Class R shares are not subject to sales charges and are available for limited groups of eligible investors, including institutional investors. All results are historical and assume the reinvestment of dividends and capital gains. Other share classes are available for which performance and expenses will differ.

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 July 1, 2005 through December 31, 2005 Investor Share Class A B C R Class - ----------------------------------------------------------------------------------------------------- Beginning Account Value $1,000.00 $1,000.00 $1,000.00 $1,000.00 $1,000.00 On 7/1/05 Ending Account Value $ 998.43 $ 995.17 $ 994.78 $1,001.67 $ 996.56 On 12/31/05 Expenses Paid During $ 6.04 $ 10.21 $ 9.70 $ 3.73 $ 8.10 Period* * Expenses are equal to the Trust's annualized expense ratio of 1.20%, 2.03%, 1.93%, 1.61% and 0.74%, for Class A, Class B, Class C, Class R and Investor Class shares, respectively, multiplied by the average account value over the period, multiplied by 184/365 (to reflect the one-half year period). 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.

In the interview below, Richard Schlanger, the Trust's day-to-day Portfolio Manager, discusses the factors that affected the fixed-income market and the Trust over the past 12 months. Q: How did the Trust perform during the period? A: For the 12-month period ended December 31, 2005, Class A shares of Pioneer America Income Trust produced a total return of 1.84% at net asset value. The Trust underperformed its benchmark, the Lehman Brothers Government Bond Index, which returned 2.65% for the same period. It also underperformed the average 2.05% 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 3.17%. The Trust had 260 issues and the average quality of the portfolio was AAA.

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: Economic growth was relatively strong, and productivity remained high. In this environment, the Federal Reserve continued to reverse its accommodative monetary policy and raised interest rates eight times during the year, each time by a quarter point. At the end of 2005, the federal funds target rate was 4.25%, up from 2.25% in January 2005. (The federal funds rate is the rate banks charge for overnight loans. Since June 2004, the Fed has hiked interest rates 13 times, taking the federal funds rate from a 40-year low of 1% to the current 4.25%.) The net effect of the Fed's actions was a flattening of the yield curve, where short-term yields and longer-term yields were approximately the same. On December 30, 2005, the yield curve inverted slightly, with longer-term yields falling below 11 Pioneer America Income Trust - -------------------------------------------------------------------------------- PORTFOLIO MANAGEMENT DISCUSSION 12/31/05 (continued) - -------------------------------------------------------------------------------- short-term yields. (The yield curve shows the relationship between bond yields and maturity lengths.) During the year, government bonds benefited from an influx of money from both foreign and domestic investors. While long-term yields on U.S. Treasuries were relatively low, they were among the highest of the developed countries and attractive to overseas investors. The performance of government bonds was also enhanced by a flight to quality. At a time when long-term yields declined and the debt of General Motors and Ford was downgraded by credit rating agencies, domestic investors saw little advantage to taking on risk. As a result, they moved into the relative safety of government securities. Q: What strategies did you use in managing the Trust? A: As interest rates rose, we extended duration, or sensitivity to interest-rate changes, by reducing exposure to mortgage securities and adding to positions in Treasury issues and Treasury Inflation Protected Securities (TIPS). TIPS are securities whose principal is tied to the consumer price index, a monthly indicator that measures the price inflation of a representative basket of goods and services. When inflation accelerates, the principal on TIPS increases in value. The interest-rate payment on TIPS is calculated on the inflated principal. While inflation was not a problem in 2005, we are concerned about the potential for it to pick up. Oil prices are over $60 a barrel, the price of gold is at a 25-year high and the unemployment rate fell below 5%. These factors and others could lead to an upturn in inflation. At the end of the period, 59% of the portfolio was in mortgage pass-through securities issued by the Government National Mortgage Association, 40% was in Treasury issues and TIPS, and 1% was in cash. Q: What detracted from performance? A: Our positioning on the yield curve held back return. Throughout the 12 months, we maintained a bulleted strategy, which means we invested in bonds across the maturity spectrum, with the biggest concentration in the intermediate-term range of two-years to ten-years. While our short-term and long-term bonds did well, intermediate-term bonds detracted from performance. In hindsight, it would have been more advantageous to have had a barbelled configuration, overweighting the short and long ends of the yield curve and holding relatively few intermediate-term bonds. 12 Pioneer America Income Trust - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- Q: What contributed to performance? A: During the second half of 2005, yields on 10-year Treasuries traded in a relatively narrow range of roughly 3.90% to a high of roughly 4.68%. As 10-year Treasuries declined in price and rose in yield, we extended duration. This aided results because 10-year Treasuries closed the year at 4.40%, down from their highs. A longer duration usually benefits a portfolio when yields decline. The performance of TIPS also helped boost the Trust's return. Q: What is your outlook? A: In general we are positive when looking ahead. While we believe the inverted yield curve may be indicating some moderating in economic growth, we do not think it is signaling recession. When the Fed began raising interest rates, the federal funds rate was extremely low at 1%. We think that the current 4.25% level is not restrictive, especially with an inflation rate of roughly 2.0% to 2.5%. While we think the consumer may cut back on spending, it is likely that business will pick up the slack. An increase in capital spending on the part of corporations may be enough to keep the economy growing at a respectable rate. The Fed may be in the late stages of its rate-raising cycle. Should the Fed ease rates somewhat, we believe intermediate-term securities will outperform longer-term securities. We are well-positioned should this occur. As we move into 2006, we believe the Trust should continue to provide income diversification for investors who want to avoid the risk associated with the more volatile areas of the fixed-income market and with equities. When interest rates rise, the prices of fixed income securities in the fund will generally fall. Conversely, when interest rates fall, the prices of fixed income securities in the fund will generally rise. Prepayment risk is the chance that mortgage-backed bonds will be paid off early if falling interest rates prompt homeowners to refinance their mortgages. Forced to reinvest the unanticipated proceeds at lower interest rates, the fund would experience a decline in income and lose the opportunity for additional price appreciation associated with falling interest rates. 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. Government guarantees apply to the underlying securities only and not to the prices and yields of the 13 Pioneer America Income Trust - -------------------------------------------------------------------------------- PORTFOLIO MANAGEMENT DISCUSSION 12/31/05 (continued) - -------------------------------------------------------------------------------- portfolio.

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 has 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. Information regarding the Trust's principal investment risks is contained in the Trust's prospectus. Please refer to those documents when considering the Trust's risks. 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: 36 Pioneer America Income Trust - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- 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, 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 December 31, 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. 37 Pioneer America Income Trust - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 12/31/05 (continued) - -------------------------------------------------------------------------------- At December 31, 2005, the Trust had a net capital loss carryforward of $12,125,464, 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, $3,175,915 will expire in 2012, and $1,904,299 will expire in 2013, if not utilized. The Trust has elected to defer approximately $1,612,711 of capital losses recognized between November 1, 2005 and December 31, 2005 to its fiscal year ending December 31, 2006. The tax character of distributions paid during the years ended December 31, 2005 and 2004 were as follows: - -------------------------------------------------------------------------------- 2005 2004 - -------------------------------------------------------------------------------- Distributions paid from: Ordinary income $9,796,927 $8,808,385 ---------- ---------- Total $9,796,927 $8,808,385 ========== ========== - -------------------------------------------------------------------------------- The following shows the components of the Trust's capital on a federal income tax basis at December 31, 2005. - -------------------------------------------------------------------------------- 2005 - -------------------------------------------------------------------------------- Undistributed ordinary income $ 57,355 Capital loss carryforward (12,125,464) Post October losses deferred (1,612,711) Unrealized depreciation (2,712,467) ------------ Total $(16,393,287) ============ - -------------------------------------------------------------------------------- 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. At December 31, 2005, the Trust reclassified $2,360,505 to decrease distributions in excess of net investment income, and $2,360,505 to increase accumulated net realized loss. This reclassification has no impact on the net assets of the Trust and presents the Trust's capital accounts on a tax basis. 38 Pioneer America Income Trust - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- 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 $17,613 in underwriting commissions on the sale of Class A shares for the year ended December 31, 2005. 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, 39 Pioneer America Income Trust - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 12/31/05 (continued) - -------------------------------------------------------------------------------- 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. 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 December 31, 2005, $6,141, 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 $74,834 in transfer agent fees payable to PIMSS at December 31, 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 40 Pioneer America Income Trust - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- 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 as compensation for distribution services. Included in due to affiliates is $4,932 in distribution fees payable to PFD at December 31, 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 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 year ended December 31, 2005, CDSCs in the amount of $110,527 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 year ended December 31, 2005, the Trust's expenses were reduced by $7,996 under such arrangements. 41 Pioneer America Income Trust - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 12/31/05 (continued) - -------------------------------------------------------------------------------- 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"): - ----------------------------------------------------------------------------------------------- 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 - -------------------------------------------------------------------------------- REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM - -------------------------------------------------------------------------------- To the Board of Trustees and Shareowners of Pioneer America Income Trust: We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of Pioneer America Income Trust (the "Trust") as of December 31, 2005, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the four years in the period then ended. These financial statements and financial highlights are the responsibility of the Trust's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. The financial highlights for the year ended December 31, 2001 were audited by other auditors who have ceased operations and whose report, dated February 15, 2002, expressed an unqualified opinion on those financial highlights. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. We were not engaged to perform an audit of the Trust's internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Trust's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements and financial highlights, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of December 31, 2005, by correspondence with the custodian. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of Pioneer America Income Trust at December 31, 2005, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and financial highlights for each of the four years in the period then ended, in conformity with U.S. generally accepted accounting principles. /s/ Ernst & Young LLP Boston, Massachusetts February 10, 2006 43 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 an index, 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 Fund's investment policies and restrictions and with the Fund's Code 44 Pioneer America Income Trust - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- 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, three, five and ten year 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 investment disciplines and providing for a large variety of Fund and shareholder services. 45 Pioneer America Income Trust - -------------------------------------------------------------------------------- FACTORS CONSIDERED BY THE INDEPENDENT TRUSTEES IN APPROVING THE MANAGEMENT CONTRACT (continued) - -------------------------------------------------------------------------------- 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 fourth quintile of the peer group for the 12 months ended June 30, 2005, the fourth quintile for the three years ended June 30, 2005, the fourth quintile for the five years ended June 30, 2005 and the fifth quintile for the ten year period ended June 30, 2005. (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 (gross of expenses) on the Fund's Class A share relative to the yield (as of June 30, 2005) on the Lehman 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 more narrow investment mandate than the peer group, 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 46 Pioneer America Income Trust - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- 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, 2005 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, 2005 was in the fifth 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 47 Pioneer America Income Trust - -------------------------------------------------------------------------------- FACTORS CONSIDERED BY THE INDEPENDENT TRUSTEES IN APPROVING THE MANAGEMENT CONTRACT (continued) - -------------------------------------------------------------------------------- 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. 48 Pioneer America Income Trust - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- 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. 49 Pioneer America Income Trust - -------------------------------------------------------------------------------- TRUSTEES, OFFICERS AND SERVICE PROVIDERS - -------------------------------------------------------------------------------- Investment Adviser Pioneer Investment Management, Inc.

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.

Non-Audit Services Beginning with non-audit service contracts entered into on or after May 6, 2003, the effective date of the new SEC pre-approval rules, the Fund's audit committee is required to pre-approve services to affiliates defined by SEC rules to the extent that the services are determined to have a direct impact on the operations or financial reporting of the Trust. For the years ended December 31, 2005 and 2004, there were no services provided to an affiliate that required the Trust's audit committee pre-approval. (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.

The aggregate non-audit fees for the Trust and affiliates, as previously defined, totaled $6,800 in 2005 and $6,000 in 2004.

The Fund's independent auditor, Ernst & Young LLP ("E&Y"), has advised the Audit Committee of the Fund's Board of Trustees that E&Ys Spanish affiliate (E&Y Spain) performed certain non-audit work for Pioneer Global Investments Limited ("PGIL"), an affiliate of the Funds investment adviser. The services involved the receipt and disbursement of monies transferred to E&Y Spain by PGIL in payment of individual payroll and related income tax withholdings due on returns prepared by E&Y Spain for certain PGIL employees located in Spain from February 2001 to October 2005. E&Y became auditors of the Fund in May 2002. These payroll and tax services were discontinued in November 2005. The annual fee received by E&Y Spain for all such services totaled approximately 9,000 Euro per year. E&Y has informed the Audit Committee that based on its internal reviews and the de minimus nature of the services provided and fees received, E&Y does not believe its independence with respect to the Fund has been impaired or that it is disqualified from acting as independent auditors to the Fund. The Trust's audit committee of the Board of Trustees has considered whether the provision of non-audit services that were rendered to the Affiliates (as defined) 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.
