LETTER TO SHAREOWNERS 6/30/05
- --------------------------------------------------------------------------------

Dear Shareowner,
- --------------------------------------------------------------------------------
The U.S. economy has expanded at an annualized rate of at least three percent
for eight straight quarters, a feat it last achieved in the 1980s. 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. For an analysis of
your holdings and some ideas to help bring your investments in line with your
aspirations, talk to your financial professional.

Please consider a fund's investment objective, risks, charges and expenses
carefully before investing. The prospectus contains this and other information
about each fund and should be read carefully before you invest or send money.
To obtain a prospectus and for other information on any Pioneer fund, contact
your financial advisor, call 1-800-225-6292 or visit our web site at

INDEX DEFINITIONS
- --------------------------------------------------------------------------------

The Lehman Brothers Government Bond Index measures the performance of the U.S.
government bond market. The Lehman Brothers Fixed-Rate Mortgage-Backed
Securities Index is an unmanaged index including 15- and 30-year fixed rate
securities backed by mortgage pools of the Government National Mortgage
Association (GNMA), Federal Home Loan Mortgage Corporation (FHLMC) and Federal
National Mortgage Association (FNMA). Index returns assume reinvestment of
dividends and, unlike Trust returns, do not reflect any fees, expenses or sales
charges. You cannot invest directly in the Indexes.

The indexes defined here pertain to the Value of $10,000 Investment charts shown
on pages 4, 5, 6, 7 and 8.

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.

NAV results represent the percent change in net asset value per share. Returns
would have been lower had sales charges been reflected. POP returns reflect
deduction of maximum 4.50% sales charge. 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.

Performance results reflect any applicable expense waivers in effect during the
periods shown. Without such waivers Trust performance would be lower. Waivers
may not be in effect for all funds. Certain fee waivers are contractual through
a specified period. Otherwise, fee waivers can be rescinded at any time. See the
prospectus and financial statements for more information.

The performance table and graph do not reflect the deduction of fees and taxes
that a shareowner would pay on Trust distributions or the redemption of Trust
shares.

(CSDC). Effective December 1, 2004, the period during which a CDSC is applied to
withdrawals was shortened to 5 years. The maximum CDSC for class B shares
continues to be 4%. For more complete information, please see the prospectus for
details. Note: Shares purchased prior to December 1, 2004 remain subject to the
CDSC in effect at the time you purchased those shares. For performance
information for shares purchased prior to December 1, 2004, please visit

Performance results reflect any applicable expense waivers in effect during the

may not be in effect for all funds. Certain fee waivers are contractual through
a specified period. Otherwise, fee waivers can be rescinded at any time. See the

The performance table and graph do not reflect the deduction of fees and taxes
that a shareowner would pay on Trust distributions or the redemption of Trust
shares.

COMPARING ONGOING FUND EXPENSES

As a shareowner in the Trust, you incur two types of costs:

(1)  ongoing costs, including management fees, distribution and/or service
     (12b-1) fees, and other Trust expenses; and

(2)  transaction costs, including sales charges (loads) on purchase payments.

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.

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.

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

    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

    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

(a)  On January 1,2001, the Trust began accreting discounts and amortizing
     premiums on debt securities. The effect of this changes for the year ended
     December 31, 2001, was to decrease net investment income by $0.01 per
     share, increase net realized and unrealized gain (loss) by $0.01 per share
     and decrease the ratio of net investment income to average net assets
     assuming waiver of management fees by PIM and reduction for fees paid
     indirectly from 4.42% to 4.25%. Per share ratios and supplemental data for
     periods prior to January 1, 2001, have not been restated to reflect this
     change in presentation.

NOTES TO FINANCIAL STATEMENTS 6/30/05 (unaudited)

1. Organization and Significant Accounting Policies

Pioneer America Income Trust (the Trust) is a Massachusetts statutory trust
registered under the Investment Company Act of 1940 as a diversified, open-end
management investment company. The investment objective of the Trust is to
provide a high level of current income consistent with preservation of capital
and prudent investment risk.

The 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

                                                                     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.

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

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

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"):

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

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

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

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.

 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.

                 firm, the scope of the Audit

- --------------------------------------------------------------------------------
GENERAL AUDIT COMMITTEE APPROVAL POLICY:
o For all projects, the officers of the Funds and the Fund's auditors will each
  make an assessment to determine that any proposed projects will not impair
  independence.

o Potential services will be classified into the four non-restricted service
  categories and the "Approval of Audit, Audit-Related, Tax and Other
  Services" Policy above will be applied. Any services outside the specific
  pre-approved service subcategories set forth above must be specifically
  approved by the Audit Committee.

o At least quarterly, the Audit Committee shall review a report summarizing the
  services by service category, including fees, provided by the Audit firm as
  set forth in the above policy.

- --------------------------------------------------------------------------------


    (2) Disclose the percentage of services described in each of paragraphs (b)
   through (d) of this Item that were approved by the audit committee pursuant
   to paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X.

    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.
