Dear Shareowner,
- --------------------------------------------------------------------------------
We know from the history of the capital markets that sudden shifts in investor
sentiment can occur with little warning, based on an assortment of events. We
believe such a shift in sentiment is occurring in reaction to the possibility
that U.S. economic growth may slow in the second half of 2006.

While U.S. markets fell in late May and early June, the economic events of the
six- and 12-month periods ending June 30, 2006, have actually been characterized
by continued low inflation at home and strong growth prospects abroad with
rising commodity and stock prices.

According to the International Monetary Fund, international economic growth in
2004-5 was the fastest of any two-year period in more than 30 years, and 2006
growth is projected to match the healthy growth of 2005. The growth has been
broad-based, with Europe, Japan, and emerging market economies all showing
strength. The result has been rising prices across a broad range of commodities,
increasing corporate profits, and higher interest rates.

The U.S. bond markets' concern has been that strong economic growth would spark
inflation - we have already seen commodity prices rise, and U.S. labor costs are
threatening to increase, since we are close to full employment. That may also be
a reason why public sentiment is becoming uneasy.

Despite strong first quarter economic growth, the U.S. economy for the second
half of the year may slow in reaction to past increases in interest rates and
energy costs. Thus far the only sign of such a slowdown has been a cooling
housing market. Yet many observers believe a slower growing economy could be
welcomed by the markets.

The U.S. Federal Reserve has continued its program of measured short-term
interest rate increases. However, the Fed Chairman, Ben Bernanke, indicated that
inflation may moderate, which would permit the Fed to stop raising interest
rates. Such action could have positive effects for both consumers and investors
over the intermediate to longer term. By restraining inflation, the Fed may also
limit upward

pressure on longer-maturity bond yields and downward pressure on stocks'
price/earnings ratios.

In summary, we think security market valuations remain reasonable, and yet there
are no guarantees in investing. The unpredictability reinforces the importance
of Pioneer's message that investors should remain diversified, take a long-term
view, and base investment decisions on economic and market fundamentals, rather
than on emotion. Our investment philosophy and approach continue to be based on
the use of fundamental research to identify a range of opportunities that offer
an attractive balance of risk and reward to help shareowners work toward their
long-term goals.

Respectfully,

/s/ Osbert M. Hood

PORTFOLIO MANAGEMENT DISCUSSION 6/30/06
- --------------------------------------------------------------------------------

During a period of solid economic growth and steadily rising interest rates,
yields on U.S. Treasury securities rose, and shareholders in Pioneer America
Income Trust earned a relatively high level of income during the first half of
2006. In the interview below, Richard Schlanger, who is responsible for
day-to-day management of the Trust, discusses the factors that affected the
fixed-income market and the Trust over the semiannual period.

Q: How did the Trust perform during the period?

A: For the six months ended June 30, 2006, Class A shares of Pioneer America
   Income Trust produced a total return of -1.68% at net asset value. The Trust
   underperformed its benchmark indices, the Lehman Brothers Government Bond
   Index, which returned -0.89%, and the Lehman Brothers Fixed-Rate
   Mortgage-Backed Securities Index, which returned -0.06% for the same period.
   The Trust also slightly lagged the average -1.61% return generated by the
   General U.S. Government Funds category of Lipper Inc., an independent monitor
   of mutual fund performance. During the six months, the Trust's yield rose
   dramatically from 3.50% to 5.23%. At the end of the period, the 30-day SEC
   yield for Class A shares was 3.80%. The Trust had 256 issues, and the average
   credit quality of the portfolio was AAA, as measured by Standard & Poor's.

   Call 1-800-225-6292 or visit www.pioneerinvestments.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 six months?

A: In a period of relatively strong economic growth and higher prices for
   commodities, concerns about the prospect of accelerating inflation dominated
   the fixed-income markets. At the Federal Reserve, the Alan Greenspan era came
   to a close, and Ben Bernanke became chairman in early February. When Mr.
   Bernanke took office, the Federal funds target rate was 4.50%. In the first
   five months of his chairmanship, the Federal funds rate rose to 5.25%, with
   the

4


Pioneer America Income Trust
- --------------------------------------------------------------------------------

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

   latest one-quarter percentage point increase occurring on June 29. (The
   Federal funds rate is the rate banks charge for overnight loans. Since June
   2004, the Federal Reserve has raised interest rates 17 times, taking the
   Federal funds rate from a 40-year low of 1% to the current 5.25%.) In the
   most recent six-month period, yields across the maturity spectrum moved
   higher in a parallel fashion.

Q: How did you manage the Trust in this environment?

A: As higher interest rates boosted mortgage rates, we became concerned about
   the duration, or sensitivity to interest-rate changes, of our mortgage
   holdings because as interest rates go up, mortgage duration tends to lengthen
   when refinancing and prepayment activity slows. To limit this drift in
   duration, we trimmed our Ginnie Mae position from 59% of net assets to 55%.
   (Ginnie Mae securities are issued by the Government National Mortgage
   Association and are backed by the full faith and credit of the U.S.
   Government.) Instead of allowing duration passively to drift upward, we chose
   to focus on longer-term Treasury securities. This positioning is consistent
   with our belief that with each additional interest-rate hike, we were
   approaching the end of the Federal Reserve's tightening cycle. We thought
   that if the Federal Reserve went too far in raising rates, economic growth
   would slow, and the central bank would have to reverse course and begin
   lowering rates. If this were to occur, we believe the Treasury market would
   rally, and longer-term Treasuries would outperform their short-term
   counterparts. As conditions warranted, we opportunistically added to or sold
   holdings in 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. At the end of the six-month period, 55.3% of the
   portfolio was in mortgage pass-through securities issued by Ginnie Mae, 43.6%
   was in Treasury securities, including TIPS, and 1.1% was in cash.

                                                                               5

- --------------------------------------------------------------------------------
PORTFOLIO MANAGEMENT DISCUSSION 6/30/06                            (continued)
- --------------------------------------------------------------------------------

Q: What contributed to performance?

A: The shorter-duration assets aided returns, as interest rates rose. Over the
   period, short-term Treasuries produced a return of 0.80%. Returns on
   longer-term Treasuries were negative. The positions in Ginnie Mae securities
   and in TIPS also contributed to performance, as TIPS and mortgages
   outperformed fixed-rate Treasuries.

Q: What detracted from performance?

A: Because the Federal Reserve was determined to fight inflation by raising
   interest rates, long-duration assets vastly underperformed short-duration
   assets. As a result, the Trust's longer-duration assets were the biggest
   detractors from performance. For the six months, five-year and 10-year
   Treasuries returned -1.35% and -3.90%, respectively. We view the
   underperformance of longer-duration assets as a relatively short-term event,
   because we believe that once the Federal Reserve stops raising interest
   rates, securities with longer durations have the potential to outperform.

Q: What is your outlook?

A: We believe that rising interest rates and oil prices have begun to affect the
   mortgage market and consumer spending. We have seen a shift away from
   adjustable-rate mortgages to fixed-rate mortgages and a decline in refinance
   activity as mortgage rates have risen. There has also been evidence of a
   decline in disposable income, and some discount retailers have reported
   slower sales. If these trends continue, economic growth is likely to slow,
   and the Federal Reserve may take a breather from raising interest rates. We
   believe the portfolio is positioned to take advantage of this type of
   environment. Our investments are scattered across the yield curve. Should
   rates stabilize or decline, we believe the portfolio's intermediate-term and
   longer-term holdings could outperform.

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. 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 Trust would experience a

6


Pioneer America Income Trust
- --------------------------------------------------------------------------------

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

decline in income and lose the opportunity for additional price appreciation
associated with falling interest rates. The Trust 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 portfolio. At times, the
Trust's investments may represent industries or industry sectors that are
interrelated or have common risks, making it more susceptible to any economic,
political, or regulatory developments or other risks affecting those industries
and sectors.

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.

deferred sales charge (CDSC). The performance of Class C shares does not reflect
the 1% front-end sales charge in effect prior to February 1, 2004. If you paid a
1% sales charge, your returns would be lower than those shown above. "If Held"

The performance data quoted represents past performance, which is no guarantee

shares, when redeemed, may be worth more or less than their original cost.

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

Pioneer America Income Trust

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"

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.

(a)  On January 1, 2001, the Trust began accreting discounts and amortizing
     premiums on debt securities. The effect of this charges for the year ended
     December 31, 2001, was to decrease net investment income by $0.02 per
     share, increase net realized and unrealized gain (loss) by $0.02 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 5.35% to 5.15%. Per share ratios and supplemental data for
     periods prior to January 1, 2001, have not been restated to reflect this
     change in presentation.

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 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:

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 June
   30, 2006, 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.

   Information regarding the Fund's principal investment risks is contained in
   the Fund's prospectus'(es). Please refer to those documents when considering
   the Fund's risks.

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 state-

                                                                              41

   ments 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, 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 current year distributions paid will be determined at
   the end of the current fiscal year. The tax character of distributions paid
   during the year ended December 31, 2005 was as follows:

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


   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

42


Pioneer America Income Trust
- --------------------------------------------------------------------------------

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

   $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.

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 $ 6,504 in underwriting commissions on the sale
   of Class A shares for the six months ended June 30, 2006.

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

                                                                              43


Pioneer America Income Trust
- --------------------------------------------------------------------------------
NOTES TO FINANCIAL STATEMENTS 6/30/06  (unaudited) (continued)
- --------------------------------------------------------------------------------

   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.

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, 2006, $4,330, 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 $86,611 in transfer agent
fees payable to PIMSS June 30, 2006.

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.

44


Pioneer America Income Trust
- --------------------------------------------------------------------------------

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

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 as compensation for distribution services.
Included in due to affiliates is $1,879 in distribution fees payable to PFD at
June 30, 2006. 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 (Class A, Class B, and Class C Shares) may be
subject to a contingent deferred sales charge (CDSC). A CDSC of 1.00% may be
imposed on redemptions of certain net asset value purchases of Class A shares
within 18 months of purchase. 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%. Proceeds from the CDSCs are paid to PFD. For the six months ended June
30, 2006, CDSCs in the amount of $73,852 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, 2006, the Trust's expenses
were reduced by $5,010 under such arrangements.

                                                                              45

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 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.

  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

  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.

for services rendered to the registrant, and rendered to the registrant's
investment adviser (not including any sub-adviser whose role is primarily

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

investment adviser), and any entity controlling, controlled by, or under common
control with the investment adviser that provides ongoing services to the

Rule 2-01 of Regulation S-X is compatible with maintaining the principal

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.
