 Dear Shareowner,
- --------------------------------------------------------------------------------

Staying diversified and keeping your portfolio invested in the markets are two
general investment principles that have served investors well over time. They
are particularly useful guides to keep in mind today, at a time when markets
around the globe are being buffeted by problems in the financial and real
estate industries and by concerns about a slowing U.S. economy.

After an extended period of steady growth with sustained low unemployment and
low inflation, the U.S. economy ran into difficulty as 2007 drew to a close.
Problems in the financial system tied to poor practices in the mortgage
financing industry and the end of home price appreciation have forced investors
and bankers to mark down the value of assets on their balance sheets. A
late-summer credit crunch forced central banks in the U.S. and Europe to assume
the role of "lender of last resort" to keep credit markets functioning. As the
repercussions of the credit crunch and falling home prices were felt in the
real economy, unemployment rose and consumer confidence fell. Inflation
concerns moved to the back burner for the U.S. Federal Reserve, which lowered
interest rates, first gradually, then more rapidly, as concern grew that
falling home prices and disruptions in financial markets posed a significant
threat to economic growth.

Markets reacted poorly to these developments, with fixed-income credit spreads
(the difference in rates between corporate and U.S. government bonds) widening
dramatically and stock markets declining. For the six months ending February
29, 2008, the Dow Jones Industrial Average fell 7%, the Standard & Poor's 500
Index declined 9% and the NASDAQ Composite Index fell 13%. The MSCI EAFE
Developed Market Index of international stock markets fell 5% during that
period. Only the MSCI Emerging Markets Index posted a positive return over the
six-month period, rising 18%. The U.S. investment-grade bond market, as
measured by the Lehman Brothers Aggregate Bond Index, rose 6% over the six
months ending February 29, 2008. The U.S. high-yield bond market, as measured
by the Merrill Lynch High Yield Bond Master II Index, fell 1% over the same
six-month period as its higher coupon yields could not offset a fall in bond
prices triggered by widening credit spreads.

Letter


Looking forward, a growing number of economists are concerned about a
recession. As always, though, emotions can get ahead of reality. Higher
mortgage defaults, a spreading of weakness to other consumer sectors or to
employment, and the possibility of a worsening of the liquidity/credit crunch
represent risks to the economy. Conversely, economic growth in the rest of the
world remains relatively positive, and a weak U.S. dollar has significantly
benefited U.S. companies competing in the global marketplace. While falling
risk tolerances may continue to depress asset prices in the short term, equity
and corporate bond valuations look reasonable unless the U.S. economy falls
into a severe recession.

Sudden swings in the markets are always to be expected. The history of the
stock market demonstrates that sharp market downturns are frequently followed
by strong recoveries, but they are also difficult to time. Just as staying
diversified and invested are important investment principles, it is also
important to pay attention to asset allocation. As always, we encourage you to
work closely with your financial advisor to find the mix of stocks, bonds and
money market assets that is best aligned to your particular risk tolerance and
investment objective.


Respectfully,

/s/Daniel K. Kingsbury

PORTFOLIO MANAGEMENT DISCUSSION 2/29/08
- --------------------------------------------------------------------------------


European equity markets slumped during the six months ending February 29, 2008,
as investors worried about potential deceleration of economic growth aggravated
by growing problems within the financials sector. In the following discussion,
Andrew Arbuthnott discusses the factors that affected the performance of
Pioneer Europe Select Equity Fund over the six months. Mr. Arbuthnott is a
member of the team at Pioneer Investment Management in Dublin, Ireland, that is
responsible for the Fund's day-to-day management.

Q:  How did Pioneer Europe Select Equity Fund perform during the six months
    ending February 29, 2008?

A:  Europe Select Equity Fund's Class A Shares had a total return of -14.00%, at
    net asset value, for the period. During the same six months, the MSCI
    Europe Index posted -4.76%, while the average return of the 107 mutual
    funds in Lipper's European Region Funds category was -6.78%.

    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 were the principal factors affecting the performance of European
    equities for the six months?

A:  The major European stock averages fell sharply during the six months as a
    result of a confluence of events that raised concerns about a potential
    downturn in the region's economy. The MSCI Europe Index, a benchmark for
    the region, fell by about 15% in local currency terms during the period.
    However, an 11% gain in the value of the euro relative to the U.S. dollar
    softened the impact of the declining stock prices on returns realized by
    U.S. investors. The value of the euro was just one of the factors that
    loomed as a drag on growth in Europe, as the stronger euro made European
    exports relatively more expensive in international markets. Growing
    trouble in the financials sector was the major factor that led to economic
    weakening. Concerns first surfaced

    over the subprime mortgage market in the United States, but the problems
    spread to Europe where many major financial institutions held assets tied
    to the U.S. mortgage market. The issue then expanded to encompass wider
    concerns about credit risk in general, resulting in a slowing of lending
    activity of all types.

    With the price of oil climbing by 38% in Europe during the six months,
    higher energy costs also appeared to brake the expansion of economies in
    Europe. Europe's Gross Domestic Product (GDP) grew by 2.6% for 2007, but
    appeared to decelerate noticeably at the end of the 2007, especially in
    the United Kingdom, Ireland and Spain. Consensus expectations were that
    GDP growth in 2008 might fall below 2%.

    Against this backdrop, stocks of the most economically sensitive companies
    tended to perform poorly. Shares of retailers, for example, fell by 23% in
    U.S.-dollar terms during the period, while diversified financials, banks
    and information technology stocks also produced weak returns during the
    period. Materials stocks were the strongest performing market sector in
    Europe, with stock returns averaging 11% in U.S. terms over the six
    months. Shares of materials companies appreciated as commodity prices rose
    and merger-and-acquisition activity increased. Other sectors turning in
    positive performance during the period included: utilities; food, beverage
    and tobacco; telecommunications services and energy.

Q:  What types of investments tended to detract from Fund performance relative
    to the MSCI Europe Index?

A:  The Fund's stock holdings tended to be in some of the weaker performing
    areas. Selections in consumer durables stocks produced particularly
    disappointing results during the period, largely due to the Fund's
    positions in Persimmon and Taylor Wimpey, two major homebuilders in the
    United Kingdom that performed very poorly. Both companies produced
    acceptable earnings in a housing market that had not gone through the
    overbuilding and speculation that has characterized the U.S. market.
    However, mortgage-related problems of financial institutions resulted in a
    decline in money for home mortgages, leading investors to avoid
    homebuilder stocks. One major mortgage issuer, Northern Rock, was in the
    process of being nationalized by the British government because of the
    mortgage squeeze.



                                                                               5

    Selections in materials stocks also did not help, as the Fund did not own
    any of the mining stocks that were involved in merger discussions for most
    of the period. We did add a position in Rio Tinto during the period, but
    we did not participate in most of the appreciation of the stock following
    its acquisition proposal by BHP Billiton. In addition, the Fund's
    investment in CRH, which supplies construction materials in the United
    States and the United Kingdom, underperformed and held back Fund results.
    Energy was another area of weakness during the period, as the Fund did not
    have positions in several strong-performing stocks, including BG, a
    British-based integrated natural gas company. The underweighting of
    utilities stocks during the period also did not help.

    Among individual holdings, Swedish telecommunications equipment company
    Ericsson performed poorly during the period, as did the Royal Bank of
    Scotland. Ericsson reduced its profit projections as it lowered its
    forecast of telecommunications infrastructure spending. Royal Bank of
    Scotland was hit both by general concerns about banking and about worries
    that it had paid too much in acquiring the Dutch bank ABN Amro shortly
    before serious concerns arose in the banking industry.

Q:  What types of investments helped the Fund's performance during the period?

A:  DNB was a notable standout during the period in the weak-performing banking
    industry. This Norwegian bank's stock gained 8% over the period, helped by
    the healthy economy in Norway, which has benefited from its exposure to
    the energy sector. In the health care equipment and services area, the
    German corporation Fresenius Medical Care, a leading global provider of
    equipment and services for patients with kidney problems, continued to
    show strong profit growth during the period. Another health care selection
    that helped performance was Roche, the Switzerland-based pharmaceutical
    company. In the media industry, Reed Elsevier, a global publishing firm
    whose stock is traded on exchanges in both the United Kingdom and the
    Netherlands, performed very well, as did British American Tobacco, whose
    stock rose by 14% in the six months. In the capital goods industry, German
    engineering giant Siemens posted strong results for the period.

Q:  What is your investment outlook?

A:  While the short-term outlook for European stocks appears challenging, we
    continue to see longer-term opportunities. On the negative side, the
    problems in the financials sector are continuing, while the strong euro
    and high energy prices have combined to hold back growth. At the same
    time, the European Central Bank has not started to lower short-term
    interest rates to stimulate growth, and earnings forecasts for 2008 tend
    to be below 2007 levels.

    However, growth in the European economy still is projected to be near 2%
    this year, which is consistent with long-term trends. The sustained
    expansion in emerging markets should help drive continued growth in
    Europe, where stock valuations are very reasonable and dividend yields
    have been averaging 4%. Moreover, European corporations in general have
    strong balance sheets, with not much debt. Their strong financial footings
    should help them sustain their dividends and support stock repurchase
    programs and other initiatives to buttress equity prices.

Investing in foreign and/or emerging markets securities involves certain risks,
including risks relating to interest rates, currency exchange rates, economic,
and political conditions. The Fund 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. The Fund invests in a limited number of securities and, as a
result, the Fund's performance may be more volatile than the performance of
funds holding more securities. 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 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.

Pioneer Europe Fund acquired the assets and liabilities of Pioneer Europe

differences in expenses.

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 (to the extent
applicable) currently in effect through 1/1/11 for Class A shares. There can be
no assurance that Pioneer will extend the expense limitations beyond such time.

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.

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.

*  Expenses are equal to the Fund's annualized expense ratio of 1.50%, 2.46%,
   2.36% and 1.00%, for Class A, Class B, Class C and Class Y shares,
   respectively, multiplied by the average account value over the period,
   multiplied by 182/366 (to reflect the one-half year 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) 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 2/29/08 (unaudited)
- --------------------------------------------------------------------------------

1.  Organization and Significant Accounting Policies
Pioneer Europe Select Equity 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 four classes of shares - Class A, Class B, Class C, and Class Y
shares. Class A, Class B and Class C Shares were first publicly offered on
December 29, 2000. Class Y shares were first publicly offered on June 24, 2005.
All Class R shares were liquidated on January 31, 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 have exclusive voting rights with respect to the distribution plans
that have been adopted by Class A, Class B and Class C shareowners,
respectively. There is no distribution plan for Class Y shares.


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 revenues and expenses during the reporting period. Actual results
could differ from those estimates.


Investing in the securities of European issuers involves unique risks compared
to investing in securities of U.S. issuers. These risks are more pronounced to
the extent the Fund invests a significant portion of its investments in any one
European region. The Fund's prospectuses contain information regarding the
Fund's principal risks. Please refer to those documents when considering the
Fund's risks.


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:

Pioneer Europe Select Equity Fund
- --------------------------------------------------------------------------------

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

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 at 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 at 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 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. 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.


                                                                              29

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

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, if any,
    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 entering 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 investments 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 Fund's


30


Pioneer Europe Select Equity Fund
- --------------------------------------------------------------------------------

    distributions may be shown in the accompanying financial statements as
    from or in excess of net investment income or as from net realized gain on
    investment transactions, or as from paid-in-capital, depending on the type
    of book/tax differences that may exist.

    The tax character of current year distributions will be determined at the
    end of the fiscal year. The tax character of distributions paid during the
    year ended August 31, 2007, was as follows:

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

    For the fiscal year ending August 31, 2007, the Fund has elected
    to pass through foreign tax credits of $743,762.

    The difference between book-basis and tax-basis unrealized appreciation is
    attributable to the tax deferral of losses on wash sales.

E.  Fund Shares


    The Fund records sales and repurchases of its shares as of trade date.
    Pioneer Funds Distributor, Inc. (PFD), the principal underwriter for the
    Fund and a wholly owned indirect subsidiary of UniCredito Italiano S.p.A.
    (UniCredito Italiano), earned $24,825 in underwriting commissions on the
    sale of Class A shares during the six months ended February 29, 2008.



                                                                              31


Pioneer Europe Select Equity Fund
- --------------------------------------------------------------------------------
NOTES TO FINANCIAL STATEMENTS 2/29/08 (unaudited)                  (continued)
- --------------------------------------------------------------------------------

F.  Class Allocations

    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 their respective percentage of adjusted net assets at the
    beginning of the day. Distribution fees are calculated based on the
    average daily net asset value attributable to Class A, Class B and Class C
    shares of the Fund, respectively (See Note 4). Class Y shares are not
    subject to a distribution plan. Shareowners of each class participate in
    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).

    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, Class C and Class Y shares can bear
    different transfer agent and distribution expense rates.

2.  Management Agreement


Pioneer Investment Management, Inc. (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 daily nets
assets up to $500 million; and 0.75% of the excess over $500 million. For the
six months ended February 29, 2008, the management fee was equivalent to a rate
of 0.85% of the average daily net assets for the period.


Effective October 1, 2007, PIM has contractually agreed to limit ordinary
operating expenses to the extent required to reduce Fund expenses to 1.50%,
2.40% and 2.40% of the average daily net assets attributable to Class A, Class
B and Class C shares, respectively. Class Y shares do not have an expense
limitation. These expense limitations are in effect through January 1, 2011 for
Class A shares and through January 1, 2009 for Class B and Class C shares.

Prior to October 1, 2007, PIM agreed to limit ordinary operating expenses to
the extent required to reduce Fund expenses to 1.75%, 2.65% and 2.65% of the
average daily net assets attributable to Class A, Class B and Class C shares,
respectively.

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

In addition, under the management agreement, management fees, administrative
costs and fees for certain other services, including accounting, regulatory
reporting and insurance, are paid by the Fund. Included in "Due to affiliates"
reflected on the Statement of Assets and Liabilities is $4,893 in management
fees, administrative costs and certain other services payable to PIM at
February 29, 2008.

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" reflected on the Statement of
Assets and Liabilities is $89,203 in transfer agent fees payable to PIMSS at
February 29, 2008.

4.  Distribution Plans

The Fund adopted Plans of Distribution with respect to Class A, Class B and
Class C shares (Class A Plan, Class B Plan and Class C Plan) in accordance with
Rule 12b-1 under the Investment Company Act of 1940. Currently under the Class
A Plan, PFD is reimbursed for distribution expenses in an amount of up to 0.25%
of the average daily net assets attributable to Class A shares. Pursuant to the
Class B Plan and the Class C Plan, the Fund 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. Included in "Due to affiliates" reflected
on the Statement of Assets and Liabilities is $1,770 in distribution fees
payable to PFD at February 29, 2008.


In addition, redemptions of each class of shares (except Class Y 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 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.
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
February 29, 2008, CDSCs in the amount of $36,282 were paid to PFD.



                                                                              33

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 February 29, 2008 the Fund's
expenses were reduced by $10,108 under such arrangements.


6.  Forward Foreign Currency Contracts


At February 29, 2008, 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 February 29, 2008,
the Fund had no outstanding portfolio hedges. The Fund's gross forward currency
settlement contracts receivable and payable were $2,186,353 and $2,187,144,
respectively, resulting in a net payable of $791 at February 29, 2008.


7.  Line of Credit Facility

The Fund, along with certain other funds in the Pioneer Family of Funds (the
Funds), collectively participate 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 February 29, 2008, the Fund had no borrowings under this
agreement.


8.  New Pronouncements

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.

APPROVAL OF INVESTMENT ADVISORY AGREEMENT
- --------------------------------------------------------------------------------


Pioneer Investment Management, Inc. (PIM) serves as the Fund's investment
adviser pursuant to an investment advisory agreement between PIM and the Fund.
The Trustees of the Fund, as required by law, determine annually whether to
continue the investment advisory agreement for the Fund.

In connection with their most recent consideration of the investment advisory
agreement for the Fund, the Trustees received and reviewed a substantial amount
of information provided by PIM in response to requests of the independent
Trustees and their independent legal counsel. The independent Trustees met on a
number of occasions with PIM and also separately with their independent legal
counsel to evaluate and discuss the information provided to them by PIM. At a
meeting held on November 13, 2007, based on their evaluation of the information
provided by PIM, the Trustees, including the independent Trustees voting
separately, unanimously approved the continuation of the investment advisory
agreement for another year.

In considering the continuation of the investment advisory agreement, the
Trustees considered various factors that they determined were relevant,
including the factors described below. The Trustees did not identify any single
factor as the controlling factor in determining to approve the continuation of
the agreement.

Nature, Extent and Quality of Services
The Trustees considered the nature, extent and quality of the services provided
by PIM to the Fund, taking into account the investment objective and strategy
of the Fund and the information related to the Fund provided to the Trustees at
each quarterly meeting. The Trustees reviewed the terms of the investment
advisory agreement. The Trustees also reviewed PIM's investment approach for
the Fund and its research process. The Trustees considered the resources of PIM
and the personnel of PIM who provide investment management services to the
Fund. They also considered PIM's compliance and legal resources and personnel.

In addition, the Trustees considered the other services that PIM provides to
the Fund under the investment advisory agreement and that, as administrator,
PIM is responsible for the administration of the Fund's business and other
affairs. It was noted that PIM supervises and monitors the performance of the
Fund's service providers and provides the Fund with personnel (including
officers) as are necessary



                                                                              35


Pioneer Europe Select Equity Fund
- --------------------------------------------------------------------------------
APPROVAL OF INVESTMENT ADVISORY AGREEMENT                          (continued)
- --------------------------------------------------------------------------------


for the Fund's operations. The Trustees considered the fees paid to PIM for the
provision of such services.

Based on these considerations, the Trustees concluded that the nature, extent
and quality of services provided by PIM to the Fund were satisfactory and
consistent with the terms of the investment advisory agreement.

Performance of the Fund
The Trustees considered the performance results of the Fund over various time
periods. They reviewed information comparing the Fund's performance with the
average performance of its peer group of funds as classified by Morningstar,
Inc. (Morningstar), an independent provider of investment company data, and
with the performance of the Fund's benchmark index. The Trustees considered
that the Fund's annualized total return was in the fifth quintile of its
Morningstar category for the one and three year periods ended June 30, 2007 and
in the third quintile of its Morningstar category for the five year period
ended June 30, 2007. (In all quintile rankings referred to throughout this
disclosure, first quintile is most favorable to the Fund's shareowners. Thus,
highest relative performance would be first quintile and lowest relative
expenses would also be first quintile.) After discussing the reasons for the
Fund's underperformance with PIM, the Trustees agreed that they would continue
to monitor the performance of the Fund especially closely.

Management Fee and Expenses
The Trustees considered information on the fees and expenses of the Fund in
comparison to the management fees of its peer group of funds as classified by
Morningstar and the expense ratios of a peer group of funds selected on the
basis of criteria determined by the independent Trustees for this purpose using
data provided by Strategic Insight Mutual Fund Research and Consulting, LLC
(Strategic Insight), an independent third party.

The Trustees considered that the Fund's management fee for the twelve months
ended June 30, 2007 was in the third quintile relative to the management fees
paid by other funds in its peer group Morningstar category for the comparable
period. The Trustees also considered that the Fund's expense ratio for the
twelve months ended June 30, 2007 was in the fifth quintile relative to its
Strategic Insight peer group. The Trustees noted PIM's agreement to lower the
contractual expense limitation for the Fund and that the lowered



36


Pioneer Europe Select Equity Fund
- --------------------------------------------------------------------------------

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


expense cap was in line with the median expense ratio of the Fund's Strategic
Insight peer group for the twelve months ended June 30, 2007. It was noted that
PIM did not currently manage any accounts with an investment objective and
strategies that were similar to the Fund.

The Trustees concluded that the management fee payable by the Fund to PIM was
reasonable in relation to the nature and quality of services provided, taking
into account the fees charged by other advisers for managing comparable mutual
funds with similar strategies. The Trustees also concluded that the Fund's
expense ratio was reasonable, taking into account the size of the Fund, the
quality of services provided by PIM, the investment performance of the Fund and
the lower contractual expense limitation agreed to by PIM with respect to the
Fund.

Profitability
The Trustees considered information provided by PIM regarding the profitability
of PIM with respect to the advisory services provided by PIM to the Fund,
including the methodology used by PIM in allocating certain of its costs to the
management of the Fund. The Trustees also considered PIM's profit margin in
connection with the overall operation of the Fund. They further reviewed the
financial results realized by PIM and its affiliates from non-fund businesses.
The Trustees considered PIM's profit margins with respect to the Fund in
comparison to the limited industry data available and noted that the
profitability of any adviser was affected by numerous factors, including its
organizational structure and method for allocating expenses. The Trustees
recognized that PIM should be entitled to earn a reasonable level of profit for
the services provided to the Fund. The Trustees concluded that PIM's
profitability with respect to the management of the Fund was not unreasonable.

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 was potential for realization of any further economies
of scale. The Trustees concluded that, because of the breakpoints in the
management fee schedule and the reduced fee rates above certain asset levels,
any perceived or potential economies of scale would be shared between PIM and
the Fund.



                                                                              37

- --------------------------------------------------------------------------------
APPROVAL OF INVESTMENT ADVISORY AGREEMENT                          (continued)
- --------------------------------------------------------------------------------


Other Benefits
The Trustees considered the other benefits to PIM from its relationship with
the Fund. The Trustees considered that affiliates of PIM serve as the Fund's
transfer agent and distributor. The Trustees considered the receipt by PIM and
its affiliates of sales loads and payments under Rule 12b-1 plans in respect of
the Fund and the other Pioneer funds and the benefits to PIM and its affiliates
from the use of "soft" commission dollars generated by the Fund to pay for
research and brokerage services. The Trustees further considered the intangible
benefits to PIM by virtue of its relationship with the Fund and the other
Pioneer funds. The Trustees concluded that the receipt of these benefits was
reasonable in the context of the overall relationship between PIM and the Fund.

Conclusion
After consideration of the factors described above as well as other factors,
the Trustees, including all of the independent Trustees, concluded that the
terms of the investment advisory agreement between PIM and the Fund, including
the fees payable thereunder, were fair and reasonable and voted to approve the
proposed continuation of the investment advisory agreement for the Fund.

 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
