Dear Shareowner,
- --------------------------------------------------------------------------------
Staying diversified and keeping your portfolio invested in the markets are two
general investment principles that have served investors well over time. Those
were particularly useful guides during the past year, as U.S. and global stock
and bond markets grew strongly during the period.

In the 12 months ending May 31, 2007, global stock markets were supported by
relatively low short-term interest rates and generally strong economies. The
U.S. stock market, as measured by the Standard & Poor's 500 Stock Index, gained
approximately 23% over the 12-month period. International developed and
emerging markets equities performed even better, with MSCI's indexes of those
regions rising approximately 27% and 39%, respectively. The general U.S. bond
market, as measured by the Lehman Brothers Aggregate Bond Index, returned
roughly 7%. The high yield market, as measured by the Merrill Lynch High Yield
Bond Master II Index, returned approximately 13% during the same period.

While still strong, the rate of U.S. economic growth has slowed over the past
year. That was due in large part to a slowdown in new home construction and in
part to the lagging effects of rising energy and commodity prices as well as
rising short-term interest rates. But slowing economic activity is also due in
part to the natural maturation of the cyclical expansion as U.S. factories
approach full utilization and the labor markets approach full employment.

We have enjoyed a cyclical recovery with strong economic growth, and while U.S.
economic growth has slowed, we believe that continuing growth at a slower rate
appears to be more likely than a recession. The Federal Reserve Board has
indicated a reduced likelihood of future rate hikes, but continues to highlight
its commitment to keeping inflationary pressures contained. This is in keeping
with "best practices" among the world's central banks: low and stable inflation
is believed to be the best backdrop for stable economic growth and low average
unemployment.

In Europe, healthy labor markets are supporting growing consumption and solid
GDP growth, helped by productivity gains and a positive operating environment
for European companies that are finding strong export markets for their goods
and services around the globe. European inflationary pressures appear to be
largely under control,

with the European Central bank remaining strongly vigilant. Japanese economic
growth continues to make progress, and the country has become a more attractive
market as deflationary problems recede. Economic growth in emerging market
countries remains faster than in the developed world as they continue to "catch
up." Leading the way is China, which continues its rise as a world economic
power.

Looking forward, we believe that the overall climate for investors generally
will continue to be positive, although valuations are less attractive than they
were a year ago and a correction after a period of strong performance is
possible. Sudden swings in the markets are always to be expected. Just as
staying diversified and invested are important investment principles, it is
also important to pay attention to asset allocation. As always, we encourage
shareholders to work closely with their financial advisor to find the mix of
stocks, bonds and money market assets that is aligned to their particular risk
tolerance and investment objective.

Respectfully,

/s/ Daniel K. Kingsbury

PORTFOLIO MANAGEMENT DISCUSSION 5/31/07
- --------------------------------------------------------------------------------

International stocks continued to rally through the first half of the Fund's
fiscal year, which ended on May 31, 2007. With the momentum of growth shifting
from the United States to Europe and many developing countries, the Fund's
investments in these foreign markets posted healthy gains, as portfolio manager
Christopher Smart discusses in the following interview. Mr. Smart is
responsible for the Fund's day-to-day management and is supported by a team of
portfolio managers and analysts.

Q:  How did Pioneer International Value Fund perform during the six months
    ended May 31, 2007?

A:  The Fund's Class A shares had a total return of 13.71% at net asset value
    for the six months. The portfolio benefited from its investments in
    Europe and emerging markets, particularly South Korea and Brazil. During
    the same period, the Fund's benchmark index, the Morgan Stanley Capital
    International (MSCI) All Country Free Index (excluding the United
    States), rose 15.1% while the average return for the 214 International
    Large-Cap Core funds in its Lipper category was 13.79%.

    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.

    The Fund held several Japanese stocks that contributed positively to
    performance, such as land developer Mitsui Fudosan and steel producer JFE
    Holdings. However, there were a handful of companies that played a role in
    the portfolio's underperformance relative to its benchmark index and peer
    group. Nidec Corp., which makes small precision motors for computer hard
    disk drives, was hurt by the advent of NAND flash memory - an alternative
    technology. Profits for Kansai Electric Power were hurt by a temporary
    shutdown at its nuclear facilities. Finally, Mizuho Financial Group
    struggled in response to lower-than-expected loan demand across Japan.
    Despite these setbacks, we continue to see good potential

    for growth in Japan, given the improvement in domestic spending and will
    keep a sharp eye on progress at these companies.

    Russia represented a much smaller weighting in the portfolio than Japan,
    but a few holdings there suffered in response to the deteriorating
    relationship between Russia and the West and concerns about the future
    profitability of oil companies there. Lukoil Holding fell as a result of
    declining oil prices and a rise in operating costs.

Q:  Why did European stocks contribute so strongly to performance?

A:  Major European economies continued to expand, while corporations on the
    continent reported generally good profit growth, with many companies
    raising their stock dividend payments to shareholders. The improvement
    extended to Germany, which had lagged other European national economies
    in recent years. Inflationary pressures remained subdued, while
    short-term interest rates continued to be relatively moderate and
    liquidity in the capital markets remained favorable - even after the
    European Central Bank raised rates during the period. Heightened
    merger-and-acquisition activity and the presence of many private equity
    funds gave further support to the markets. The returns realized by U.S.
    investors in Europe were helped further as the euro gained in value
    against the U.S. dollar during the first part of 2007.

    In Germany, the industrial conglomerate Siemens experienced strong demand
    across most of its product divisions, which, in turn, gave it more pricing
    power in the markets that it serves. Against a backdrop of increased
    merger activity, another holding, ABN AMRO, saw its stock price climb
    sharply as it became a target of a bidding war by several European banks.

Q:  espite a pullback in the spring of 2006 and a sharp decline this past
    February, the emerging markets performed quite well. What contributed to
    this momentum?

A:  Emerging markets continued to build on the impressive rally that began in
    the fourth quarter of 2002. An extremely favorable environment of solid
    growth, stable interest rates, a strong appetite for risk among
    investors, and abundant liquidity in the world financial system have
    provided a firm foundation for performance. Developments within the asset
    class itself have


                                                                               5

PORTFOLIO MANAGEMENT DISCUSSION 5/31/07                             (continued)

    been equally positive. Fiscal restraint by emerging market governments has
    resulted in lower debt, falling interest rates and, in many cases, budget
    surpluses. On the corporate level, robust profit growth and the spread of
    shareholder-friendly management practices continue to be important themes.
    These developments, in turn, have led to increased confidence and rising
    participation among overseas investors. Robust economic growth has also
    contributed to the growth of a middle class - along with rising consumer
    spending - in countries that in the past relied heavily on exports to fuel
    their economies.

    The Fund's performance was especially helped by its exposure to South
    Korea and Brazil. South Korea has become the world's largest shipbuilder.
    Hyundai Heavy Industries, which more than doubled in price during the
    six-month reporting period, and Daewoo Heavy Industries were prime
    beneficiaries of surging global demand and are booking orders out three
    years for their ships. Unibanco, Brazil's third largest bank, is
    benefiting from a continued acceleration of consumer spending and growth
    in its credit card business and consumer lending operations. The Brazilian
    mining company CVRD climbed in response to strong iron ore, nickel and
    aluminum prices.

Q:  What is your outlook for the coming months?

A:  We remain optimistic that growth in continental Europe, Japan and the
    emerging markets can offset much of the slowdown in the United States, at
    least as long as America's unemployment rate is subdued and wages are
    growing. While we do not expect European stock markets to repeat their
    robust results for 2005 and 2006, we continue to have a positive outlook.
    European stocks have remained reasonably priced, with very competitive
    dividends, even if earnings growth rates were to slow, as we expect.
    European equities have remained competitively valued compared to other
    asset classes, and the corporate sector generally seems to be in solid
    financial shape, with healthy cash flows, strong balance sheets and
    reasonable debt levels. We continue to see good potential for growth in
    Japan, given the improvement in domestic spending - a sign of rising
    consumer confidence. On the corporate level, companies have a lot of
    money on their balance sheets to invest in new factories and other
    infrastructure projects.

    There is always a degree of risk with investing in emerging markets, but
    we believe the long-term outlook remains favorable due to the continued
    improvements in its fundamental underpinnings. The rapid improvements in
    government finances, corporate governance practices, and political
    stability are all keys to the emerging markets' outperformance in recent
    years, and we expect that these improvements will continue in the years
    ahead. The result is that the asset class seems to be more resilient to
    external shocks than it has been in the past. In short, we believe the
    inevitable declines that periodically occur in emerging market stocks
    should not obscure the positive, longer-term story that continues to
    unfold.

Investing in foreign and/or emerging markets securities involves risks relating
to interest rates, currency exchange rates, economic, and political conditions.
The portfolio may invest a substantial amount of its assets in issuers located
in a limited number of countries and therefore is susceptible to adverse
economic, political or regulatory developments affecting those countries. At
times, the Fund'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 or sectors.

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 5.75% 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 Fund 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 net expense ratio reflects contractual expense limitations currently in
effect through 4/1/09 for Class A Shares. There can be no assurance that Pioneer
will extend the expense limitations beyond such time. Please see the prospectus

Class C shares held for less than one year are also subject to a 1% contingent
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" results represent the percent change in net asset value per share.
Returns would have been lower had sales charges been reflected. 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

Pioneer International Value Fund

COMPARING ONGOING FUND EXPENSES
- --------------------------------------------------------------------------------
As a shareowner in the Fund, you incur two types of costs:

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

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

This example is intended to help you understand your ongoing expenses (in
dollars) of investing in the Fund 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 Fund'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.

   2.39%, and 1.98% for Class A, Class B, Class C and Class R shares,
   respectively, multiplied by the average account value over the period,

Hypothetical Example for Comparison Purposes

The table below provides information about hypothetical account values and
hypothetical expenses based on the Fund's actual expense ratio and an assumed
rate of return of 5% per year before expenses, which is not the Fund'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
Fund 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), or redemption fees 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.

NOTES TO FINANCIAL STATEMENTS 5/31/07 (unaudited)

1.  Organization and Significant Accounting Policies
Pioneer International Value Fund (the Fund) is a Massachusetts business trust
registered under the Investment Company Act of 1940 as a diversified, open-end
management investment company. The investment objective of the Fund is
long-term growth of capital.

The Fund offers three classes of shares - Class A, Class B, and Class C shares.
Class R shares were first publicly offered on April 1, 2003 and ceased
operations on February 1, 2007. Each class of shares represents an interest in
the same portfolio of investments of the Fund 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, and Class C shareowners, respectively.

The Fund's financial statements have been prepared in conformity with U.S.
generally accepted accounting principles that require the management of the
Fund 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 gain or loss on investments during the
reporting year. Actual results could differ from those estimates.

Information regarding the Fund's principal investment risks is contained in the
Fund's prospectus. Please refer to those documents when considering the Fund's
risks. Investing in foreign and/or emerging markets securities involves risks
relating to interest rates, currency exchange rates, economic, and political
conditions. The portfolio may invest a substantial amount of its assets in
issuers located in a limited number of countries and therefore is susceptible
to adverse economic, political or regulatory developments affecting those
countries. At times, the Fund'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.

The following is a summary of significant accounting policies followed by the
Fund in the preparation of its financial statements, which are consistent with
those policies generally accepted in the investment company industry:


                                                                              33

NOTES TO FINANCIAL STATEMENTS 5/31/07 (unaudited)                   (continued)
- --------------------------------------------------------------------------------

A.  Security Valuation

    Security transactions are recorded as of trade date. The net asset value
    of the Fund 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 using the last
    sale price on the principal exchange where they are traded. Securities
    that have not traded on the date of valuation, or securities for which
    sale prices are not generally reported, are valued using the mean between
    the last bid and asked prices. 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. The Fund invests primarily
    in securities of non-U.S. issuers. The principal exchanges and markets for
    such securities have closing times prior to the close of the NYSE.
    However, the value of these securities may be influenced by changes in
    global markets occurring after the closing times of the local exchanges
    and markets up to the time the Fund determines its net asset value.
    Consequently, the Board of Trustees of the Fund has determined that the
    use of daily fair valuations as provided by a pricing service is
    appropriate for the Fund. The Fund may also take into consideration other
    significant events in determining the fair value of these securities.
    Thus, the Fund's securities valuations may differ from prices reported by
    the various local exchanges and markets. Temporary cash investments are
    valued at cost which approximates market value.

    Dividend income is recorded on the ex-dividend date, except that certain
    dividends from foreign securities where the ex-dividend date may have
    passed are recorded as soon as the Fund becomes aware of the ex-dividend
    data in the exercise of reasonable diligence. Dividend and interest
    income, including interest on income bearing cash accounts, is recorded on
    the accrual basis, net of unrecoverable foreign taxes withheld at the
    applicable country rates.

    Gains and losses on sales of investments are calculated on the identified
    cost method for both financial reporting and federal income tax purposes
    and are reported net of foreign taxes on capital gains at the applicable
    country rates.

B.  Foreign Currency Translation

    The books and records of the Fund are maintained in U.S. dollars. Amounts
    denominated in foreign currencies are translated into U.S. dollars using
    current exchange rates.

    Net realized gains and losses on foreign currency transactions represent,
    among other things, the net realized gains and losses on foreign currency
    contracts, disposition of foreign currencies and the difference between
    the amount of income accrued and the U.S. dollars actually received.
    Further, the effects of changes in foreign currency exchange rates on
    investments are not segregated in the statement of operations from the
    effects of changes in market price of those securities but are included
    with the net realized and unrealized gain or loss on investments.

C.  Forward Foreign Currency Contracts

    The Fund enters into forward foreign currency contracts (contracts) for
    the purchase or sale of a specific foreign currency at a fixed price on a
    future date as a hedge or cross-hedge against either specific investment
    transactions (settlement hedges) or portfolio positions (portfolio
    hedges). All contracts are marked to market daily at the applicable
    exchange rates, and any resulting unrealized gains or losses are recorded
    in the Fund's financial statements. The Fund records realized gains and
    losses at the time a portfolio hedge is offset by entry into a closing
    transaction or extinguished by delivery of the currency. Risks may arise
    upon entering into these contracts from the potential inability of
    counterparties to meet the terms of the contract and from unanticipated
    movements in the value of foreign currencies relative to the U.S. dollar
    (see Note 6).

D.  Federal Income Taxes

    It is the Fund'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 source of the Fund's


                                                                              35

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

    distributions may be shown in the accompanying financial statements as
    either from or in excess of 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 November 30, 2006, the Fund had a net capital loss carry forward of
    $42,042,391 of which the following amounts will expire between 2009 and
    2011 if not utilized: $7,295,608 in 2009, $21,765,862 in 2010 and
    $12,980,921 in 2011.

    The tax character of current year distributions will be determined at the
    end of the current fiscal year. The tax character of distributions paid
    during the year ended November 30, 2006 was as follows:

    commissions on the sale of Class A shares during the six months ended May
    31, 2007.

F.  Class Allocations

    Distribution fees are calculated based on the average daily net assets
    attributable to Class A, Class B and Class C shares of the Fund,
    respectively (see Note 4). 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 Fund
    level and allocated daily to each class of shares based on the respective
    percentage of adjusted net assets at the beginning of the day.

    Distributions to shareowners are recorded as of the ex-dividend date.
    Distributions paid by the Fund 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 and Class C shares can bear different
    transfer agent and distribution fees.

G.  Security Lending

    The Fund lends securities in its portfolio to certain broker-dealers or
    other institutional investors, with the Fund's custodian acting as the
    lending agent. When entering into a loan, the Fund receives collateral,
    which is maintained by the custodian and earns income in the form of
    negotiated lenders' fees. The Fund also continues to receive interest or
    payments in lieu of dividends on the securities loaned. Gain or loss on
    the fair value of the loaned securities that may occur during the term of
    the loan will be for the account of the Fund. The loans are secured by
    collateral of at least 102%, at all times, of the fair value of the
    securities loaned. The fair value of collateral will be adjusted daily to
    reflect any price fluctuation in the value of the loaned securities. The
    Fund has the right under the lending agreement to recover the securities
    on loan from the borrower on demand. The Fund invests cash collateral in
    Time Deposits, which is sponsored by Brown Brothers Harriman & Co., the
    Fund's custodian.


                                                                              37

H.  Repurchase Agreements

    With respect to repurchase agreements entered into by the Fund, the value
    of the underlying securities (collateral), including accrued interest
    received from counterparties, 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 Fund's custodian, or subcustodians. The
    Fund'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
Fund's portfolio. Management fees are calculated daily at the annual rate of
0.85% of the Fund's average net assets up to $500 million and 0.75% of the
excess over $500 million. For the six months ended May 31, 2007, the management
fee was equivalent to a rate of 0.85% of average daily net assets.

Prior to January 1, 2006, the Fund's management fee was 0.95% of the Fund's
average daily net assets up to $300 million; 0.85% of the next $200 million;
and 0.75% of excess over $500 million. Prior to January 1, 2005, the Fund's
management fee was 1.00% of the Fund's average daily net assets up to $300
million, 0.85% of the next $200 million and 0.75% of excess over $500 million.

PIM has agreed not to impose all or a portion of its management fee and to
assume other operating expenses of the Fund to the extent necessary to limit
the Fund's expenses to 1.70%, 2.60% and 2.60%, of the average daily net assets
attributable to Class A, Class B and Class C shares, respectively. These
expense limitations are in effect through April 1, 2009 for Class A and through
April 1, 2008 for Class B and Class C 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 Fund. At May 31, 2007, $14,919 was payable to PIM
related to management fees, administrative fees and certain other expenses, 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 Fund at
negotiated rates. Included in due to affiliates is $140,603 in transfer agent
fees payable to PIMSS at May 31, 2007.

4.  Distribution and Service Plans

The Fund adopted a Plan of Distribution for each class of shares (Class A Plan,
Class B Plan and Class C Plan) in accordance with Rule 12b-1 under the
Investment Company Act of 1940. Pursuant to the Class A Plan, the Fund pays PFD
a service fee of up to 0.25% of the Fund's average daily net assets
attributable to Class A shares in reimbursement of its actual expenditures to
finance activities primarily intended to result in the sale of Class A shares.
Pursuant to the Class B Plan and Class C Plan, the Fund pays PFD 1.00% of the
average daily net assets attributable to Class B and Class C 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. Included in
due to affiliates is $1,677 in distribution fees payable to PFD at May 31,
2007.

In addition, redemptions of each class of shares may be subject to a contingent
deferred sales charge (CDSC). A CDSC of 1.00% may be imposed on redemptions of
certain net asset value purchases of Class A shares within 18 months of
purchase. Class B shares 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 as part of an exchange
or acquired as a result of a reorganization of another fund into the Fund
remain subject to any contingent deferred sales charge that applied to the
shares you originally 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 May 31, 2007, CDSCs in the amount of $12,782 were
paid to PFD.

Prior to September 1, 2006, the Fund charged a 2.0% redemption fee on each
class of shares sold within 30 days of purchase. Effective August 31, 2006,
this redemption fee is no longer charged.


                                                                              39

5.  Expense Offset Arrangements

The Fund has entered into certain expense offset arrangements with PIMSS
resulting in a reduction in the Fund's total expenses, due to interest earned
on cash held by PIMSS. For the six months ended May 31, 2007, the Fund's
expenses were reduced by $15,227, under such arrangements.

6.  Forward Foreign Currency Contracts

At May 31, 2007, the Fund had entered into various contracts that obligate the
Fund to deliver currencies at specified future dates. At the maturity of a
contract, the Fund must make delivery of the foreign currency. Alternatively,
prior to the settlement date of a portfolio hedge, the Fund may close out such
contracts by entering into an offsetting hedge contract. At May 31, 2007, the
Fund had no outstanding portfolio hedges. The Fund's gross forward currency
settlement contracts receivable and payable were $753,345 and $756,140,
respectively, resulting in a net payable of $2,795.

7.  Line of Credit Facility

The Fund, along with certain other funds in the Pioneer Family of Funds (the
Funds), collectively participates in a $200 million committed, unsecured
revolving line of credit facility. Borrowings are used solely for temporary or
emergency purposes. The Fund may borrow up to the lesser of $200 million or the
limits set by its prospectus for borrowings. Interest on collective borrowings
is payable at the Federal Funds Rate plus 1/2% on an annualized basis. The
Funds pay an annual commitment fee for this facility. The commitment fee is
allocated among such Funds based on their respective borrowing limits. For the
six months ended, May 31, 2007, the Fund had no borrowings under this
agreement.

8.  New Pronouncements

On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48).
FIN 48 provides guidance for how uncertain tax positions should be recognized,
measured, presented and disclosed in the financial statements. FIN 48 requires
the evaluation of tax positions taken or expected to be taken in the course of
preparing the Fund's tax returns to determine whether the tax positions have a
"more-likely-than-not" probability of being sustained by the

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

applicable tax authority. Tax positions deemed to not meet the
more-likely-than-not threshold would be recorded as a tax benefit or expense in
the reporting period in which they are realized. Adoption of FIN 48 is required
for fiscal years beginning after December 15, 2006 and is to be applied to all
open tax years as of no later than November 30, 2007. At this time, management
is evaluating the implications of FIN 48 and any impact in the financial
statements has not yet been determined.

In addition, in September 2006, Statement of Financial Accounting Standards No.
157, Fair Value Measurements (SFAS 157), was issued and is effective for fiscal
years beginning after November 15, 2007. SFAS 157 defines fair value,
establishes a framework for measuring fair value and expands disclosures about
fair value measurements. Management is currently evaluating the impact the
adoption of SFAS 157 will have on the Fund's financial statement disclosures.

 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.
