Dear Shareowner,
- --------------------------------------------------------------------------------
As the global economy reacted to good and bad news of 2006, overall it managed
to keep chugging along with fairly stable growth. Looking back, the economic
stories included slowing economic growth bringing monetary tightening to an end
in the United States, price action in oil and other commodity markets
threatening to unsettle global growth and inflation, geopolitical uncertainties
and corporate earnings growth surpassing market expectations.

Global growth surpassed most analyst expectations in 2006. The International
Monetary Fund estimates world output increased by 5.1% in 2006, up from 4.9% in
2005 and above the 3.7% average annual pace of growth of the previous 20 years.
Growth is estimated to slow modestly in 2007 but to remain well above the
long-term average.

U.S. economic growth slowed gradually over 2006, with full-year growth of GDP of
3.1%, modestly below 2005 growth but still strong enough to lower the
unemployment rate to 4.5%. While many observers were concerned that a weakening
housing sector could be a drag on consumer spending, the consumer has shown
resilience supported by a strong labor market and associated income growth and
by oil and gasoline prices falling from record highs in the second half of 2006.
Corporate America has also proved resilient in the face of the slowing housing
sector, with business investment growing at its fastest rate since 2000.

The Federal Reserve stopped increasing interest rates in mid-2006, but has
retained its bias to tighten rates, reflecting upside risks to inflation,
particularly from the tight labor market, and confidence that the economy
remained on solid ground. Consumers welcomed the relief from oil prices that
peaked at mid-year and fell sharply towards year-end. Likewise, in the second
half of 2006, they benefited from the modest easing of core inflation (which
excludes energy and food items), though such core inflation remains above what
is generally considered the central bank's "comfort zone."

The European economy surpassed many economists' expectations in 2006. Eurozone
GDP grew at a 3% pace, much stronger than its 1.8% average annual growth pace
since 2000. Underlying this strength has been buoyant and broad-based strength
in business sentiment and investment and in exports. While household consumption
showed mixed results, the unemployment rate fell to 7.7% by the end of 2006. The
European Central Bank raised interest rates gradually to 3.5% over the course of
2006, reflecting firm economic growth, steadily tightening labor market
conditions, and fast growing money supply. Core inflation in the Eurozone
remains reasonably benign, at roughly 1.5% per annum. European stock markets
posted strong returns; appreciation of the Euro relative to both the dollar and
Yen made the Eurozone stock market the top performer of 2006.

The Japanese economy continued to grow firmly in 2006. Business investment was
the major driver of expansion as increasing capacity utilization and better
sentiment encouraged a new wave of investment. As deflation ended, the Bank of
Japan ended its zero interest rate policy, although it has raised rates to only
0.25% in 2006. After a strong showing in 2005, the Japanese stock market posted
only muted gains in 2006.

Emerging economies enjoyed strong, relatively uninterrupted economic growth in
2006. Good financing conditions, buoyant commodity prices, which boosted income
and investment in commodity exporting countries, and strong export demand from
developed economies drove this growth. The emerging market stock

index was very strong in early 2006, sold off to near start-of-year levels, then
rallied to finish the year only marginally behind the Eurozone. We believe
similar growth can be expected in the emerging markets if current domestic
economic and political conditions prevail.

While global economic momentum has started to slow, we expect the global economy
to continue growing firmly in 2007, supported by business investment, rising
employment, and lower energy prices. A slowdown in the U.S. growth rate would be
welcome, since rapid growth could increase the risk of inflationary pressures,
which would force the Federal Reserve to raise interest rates. We expect Europe
and Japan to grow similarly, while emerging market economies are expected to
continue their strong growth. In this scenario, fixed-income assets are expected
to produce total returns generally in line with their current yields, while
equities are expected to produce returns generally in line with earnings growth,
which we forecast to be moderately above bond yields.

Our cautiously optimistic outlook on most regions of the world and asset classes
reinforces the importance of Pioneer Investments' message that investors should
remain diversified, take a long-term view rather than over-reacting to breaking
news, 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 Fund shareowners work toward
achieving their long-term goals.

Respectfully,

PORTFOLIO MANAGEMENT DISCUSSION 2/28/07
- --------------------------------------------------------------------------------

European equity markets sustained their upward trajectory during the six months
ended February 28, 2007, propelled by a healthy economy and improving corporate
profitability. In the following interview, Andrew Arbuthnott discusses the
events and factors that affected the performance of Pioneer Europe Select Equity
Fund over the six months. Mr. Arbuthnott is responsible for the Fund's
day-to-day management and is supported by a team of portfolio managers and
analysts.

Q:   How did Europe Select Equity Fund perform during the six months ended
     February 28, 2007?

A:   The Fund's Class A shares had a total return of 10.93%, at net asset value,
     for the six months. During the same period, the Fund's benchmark, the MSCI
     Europe Index, returned 12.74%, while the average return of the 101 funds in
     Lipper's European Funds category was 13.55%.

     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 in Europe during the six months
     ended February 28, 2007?

A:   European stock markets performed quite well, even with a rather sudden
     decline of equities in the final two days of the period. 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 3.2% in value
     against the U.S. dollar during the six months.

     The automotive industry led the market performance for the six months,
     rising by 30% in U.S. dollar terms. Other leading industries included
     capital goods, telecommunications, transportation, materials and utilities.
     The pharmaceutical industry produced the worst performance of any area in
     the economy for the six months, while the information technology, banking,
     and beverage and tobacco companies also tended to lag the market.

Q:   What types of investments had the greatest impact on Fund performance?

A:   The Fund's overweighting of the automotive industry, combined with good
     stock selection of auto-related stocks, helped substantially. Porsche, for
     example, rose by 29%, based on good earnings and cash flow generated by the
     success of its new car models. Michelin, the global tire company, was
     another major contributor before we sold it during the reporting period to
     take profits. Our selections in diversified financials also helped, with
     Credit Suisse a notable contributor during the six months. We were
     neutral-weighted, relative to the benchmark index, in the energy industry,
     but favorable stock selection added to returns. The position in Repsol, the
     Spanish-based oil company, was a significant help. WPP, the U.K.-based
     advertising and communications group, also did very well, rising by 20%,
     including the currency effect, for the six months. In the transportation
     industry, two standouts were TNT, the Dutch-based postal and express
     delivery company, and Ryanair, the Irish-based airline that has become the
     leading low-cost operator in Europe. From the materials sector, we had
     excellent performance from Swiss-based Holcim, a global leader in the
     cement industry with strong presence in both developed and emerging
     markets.

     Hurting results was our underweight position in the telecommunications
     services sector, which did well during the second half of 2006. We remained
     unenthusiastic about stocks in this area, however, because of concerns
     about pressures from intensified competition, the risks of greater
     regulatory initiatives, and the potential of new technologies changing the
     nature of competition. Our de-emphasis of utilities stocks also did not
     help. Stock prices


                                                                               5

     in this sector rose, aided by brisk merger-and-acquisition activity,
     despite our concerns about company valuations. Similarly, our
     underweighting of insurance stocks did not help when they outperformed the
     market. In the capital goods industry, our holdings produced positive
     results but nevertheless failed to keep up with the industry average return
     of 27% in U.S. dollar terms. Capital goods holdings that proved to be a
     drag on results during the six months included Siemens of Germany. In the
     consumer services area, our holding in Opap, a Greek company involved in
     the gaming industry, proved disappointing as its profits failed to meet
     market expectations.

Q:   What is your investment outlook?

A:   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 remain reasonably priced and dividends are very competitive, even if
     earnings growth rates should decelerate, as we expect. European equities
     remain competitively valued compared to other asset classes, and the
     corporate sector generally is in solid financial shape, with healthy cash
     flows, strong balance sheets and reasonable debt. Many companies are using
     their cash either to increase dividend payouts, invest to expand, or to
     fund acquisition activities. There are risk factors present, however. Oil
     and commodity prices remain high, even after receding during the second
     half of 2006, and we think there may be some weakening in the value of the
     U.S. dollar.

     We think these risk factors are moderate and that European stocks remain
     attractive.

Investing in foreign and/or emerging markets securities involves 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.

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.

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 Select
Fund (the predecessor fund) on June 24, 2005 and changed its name to Pioneer
Europe Select Equity Fund. Returns prior to June 24, 2005 reflect the
performance of the predecessor fund, which has not been restated to reflect any
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 currently in
effect through 1/1/09 for Class A Shares. There can be no assurance that Pioneer
will extend the expense limitations beyond such time. Please see the prospectus
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 Fund distributions or the redemption of Fund
shares.

The Morgan Stanley Capital International (MSCI) Europe Index measures the
performance of stocks in European developed markets. Index returns are
calculated monthly, assume reinvestment of dividends and, unlike Fund returns,
do not reflect any fees, expenses or sales charges. You cannot invest directly
in an Index.

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.

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 2/28/07 (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 R and Class Y shares were first publicly offered on
June 24, 2005. All Class R shares were liquidated on February 1, 2007. Shares of
Class A, Class B, Class C, Class R and Class Y each represent 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, Class C and Class R 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. 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.

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:


                                                                              29

NOTES TO FINANCIAL STATEMENTS 2/28/07  (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 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 amortized
     cost.

     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.

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.

     At February 28, 2007, the Fund had no outstanding portfolio hedges or
     settlement hedges.

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


                                                                              31

     federal income tax rules. Therefore, the sources of the Trust's
     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 August 31, 2006, the Fund had a net capital loss carry forward of
     $8,023,036, which will expire in 2011 if not utilized.

     At August 31, 2006, the Fund has reclassified $264,447 to decrease
     accumulated net investment income and $264,447 to decrease accumulated net
     realized loss on investments and foreign currency transactions to reflect
     permanent book/tax differences. The reclassification has no impact on the
     net asset value of the Fund and is designed to present the Fund's capital
     accounts on a tax basis.

     The tax character of distributions paid will be determined at the end of
     the current fiscal year. The tax character of distributions paid during the
     year ended August 31, 2006, was as follows:

     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 $19,199 in underwriting commissions on the
     sale of Class A shares during the six months ended February 28, 2007.

F.   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 Fund,
     respectively (See Note 4). Class Y 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 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.

     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, Class R and Class Y shares can bear
     different transfer agent and distribution fees.

2.   Management Agreement

Pioneer Investment Management, Inc. (PIM), a wholly owned indirect subsidiary of
UniCredito Italiano, manages the Trust's portfolio. Management fees are
calculated daily at the annual rate of 0.85% of the Fund's average daily nets
assets up to $500 million; and 0.75% of the excess over $500 million. The
management fee was equivalent to 0.85% of the average daily net assets for the
period.

Effective June 24, 2005, PIM has contractually agreed to limit ordinary
operating expenses to the extent required to reduce Fund expenses to 1.75%,
2.65%, 2.65% and 2.00% of the average daily net assets attributable to Class A,
Class B, Class C and Class R shares,


                                                                              33

respectively. Class Y shares do not have an expense limitation. These expense
limitations are in effect through January 1, 2009 for Class A shares and through
January 1, 2008 for Class B, Class C and Class R shares.

Prior to the merger, PIM had contractually agreed not to impose all or a portion
of its management fee and to assume other operating expenses of Pioneer Europe
Select Fund to the extent necessary to limit Class A expenses to 1.75% of the
average daily net assets attributable to Class A shares. The portion of the
Fund-wide expenses attributable to Class B and Class C shares were reduced only
to the extent that such expenses are reduced for Class A shares.

In addition, under the management fees, administrative costs and certain other
services and costs, including accounting, regulatory reporting and insurance
premiums, are paid by the Fund. At February 28, 2007, $6,086 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 Fund at
negotiated rates. Included in due to affiliates is $162,967 in transfer agent
fees payable to PIMSS at February 28, 2007.

4.   Distribution Plans

The Fund adopted Plans of Distribution with respect Class A, Class B, Class C,
and Class R shares (Class A Plan, Class B Plan, Class C Plan, and Class R 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
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 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. Pursuant to
the Class R Plan, the Fund pays PFD 0.50% of the average daily net assets
attributable to Class R shares for distribution services.

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

Included in due to affiliates is $2,646 in distribution fees payable to PFD at
February 28, 2007. The Fund has also adopted a separate service plan for Class R
shares (Service Plan). The Service Plan authorizes the Fund to pay securities
dealers, plan administrators or other service organizations that agree to
provide certain services to retirement plans or plan participants holding shares
of the Fund a service fee of up to 0.25% of the Fund's average daily net assets
attributable to Class R shares held by such plans.

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 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. Redemptions of Class C shares
within one year of purchase are subject to a CDSC of 1.00%. There are no CDSCs
for Class R shares. Proceeds from the CDSCs are paid to PFD. For the six months
ended February 28, 2007 CDSCs in the amount of $12,677 were paid to PFD.

5.   Expense Offset Arrangements

The Fund can enter 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 28, 2007 the Fund's expenses were
reduced by $12,185 under such arrangements.

6.   Subsequent Event

On September 19, 2006, the Board of Trustees approved the liquidation of the
Fund's Class R shares. This liquidation took place on February 1, 2007.


                                                                              35

7.   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 June 29, 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.

FACTORS CONSIDERED BY THE INDEPENDENT TRUSTEES IN
APPROVING THE MANAGEMENT CONTRACT
- --------------------------------------------------------------------------------

The Investment Company Act of 1940 requires that both the Board of Trustees and
a majority of the Independent Trustees (collectively "the Trustees"), voting
separately, annually approve the Fund's management contract (the "Management
Contract"). The Trustees have determined that the terms of the Management
Contract are fair and reasonable and that renewal of the contract: (i) will
enable the Fund to receive quality investment advisory services at a fee deemed
reasonable; and (ii) is in the best interests of the Fund and its shareowners.
In making such determinations, the Independent Trustees relied upon the
assistance of counsel to the Independent Trustees and counsel to the Fund.

Throughout the year, the Independent Trustees regularly met in executive
session, separately from the Interested Trustees of the Fund and any officer of
Pioneer Investment Management, Inc., the Fund's adviser (the "Investment
Adviser"), or its affiliates. While the Trustees, including the Interested
Trustees, act on all major matters relating to the Fund, a significant portion
of the activities of the Board of Trustees (including certain of those described
herein) is conducted through committees, the members of which are comprised
exclusively of Independent Trustees. Such committee meetings are attended by
officers of the Fund and/or officers of the Investment Adviser to the extent
requested by the members of the committee.

In evaluating the Management Contract, the Trustees conducted a review that was
specifically focused upon the renewal of the Management Contract, and also
relied upon their knowledge, resulting from their meetings throughout the year,
of the Investment Adviser, its services and the Fund. Both in meetings
specifically dedicated to renewal of the Management Contract and at other
meetings during the course of the year, the Trustees, including the Independent
Trustees, received materials relating to the Investment Adviser's investment and
management services under the Management Contract. These materials included
information on (i) the investment performance of the Fund, a peer group of funds
as classified by Morningstar, Inc., an independent evaluation service
("Morningstar") and an index considered appropriate by the Independent Trustees
for this purpose, (ii) sales and redemption activity in respect of the Fund,
(iii) the general investment outlook in the markets in which the Fund invests,
(iv) arrangements in respect of the distribution of the Fund's shares, (v) the
procedures employed to determine the value of each of the Fund's assets, (vi)
the Investment Adviser's management of the relationships with the Fund's
unaffiliated service providers, (vii) the record of


                                                                              37

FACTORS CONSIDERED BY THE INDEPENDENT TRUSTEES IN
APPROVING THE MANAGEMENT CONTRACT                                  (continued)
- --------------------------------------------------------------------------------

compliance with the Fund's investment policies and restrictions and with the
Fund's Code of Ethics and the structure and responsibilities of the Investment
Adviser's compliance department and (viii) the nature, cost and character of
non-investment management services provided by the Investment Adviser and its
affiliates.

Specifically in connection with the Independent Trustees' review of the
Management Contract, the Independent Trustees requested, and the Investment
Adviser provided, additional information in order to evaluate the quality of the
Investment Adviser's services and the reasonableness of the fee under the
Management Contract. Among other items, this information included data or
analyses of (1) investment performance for one, three and five year periods for
the Fund and a peer group of funds selected on the basis of criteria considered
appropriate by the Independent Trustees for this purpose, (2) management and
other fees incurred by a peer group of funds selected on the basis of criteria
considered appropriate by the Independent Trustees for this purpose, (3) the
advisory fees of comparable portfolios of other clients of the Investment
Adviser, (4) expense ratios for the Fund and a peer group of funds selected on
the basis of criteria considered appropriate by the Independent Trustees for
this purpose, (5) the overall organization of the Investment Adviser, (6) the
Investment Adviser's financial results and condition, including its and certain
of its affiliates' profitability in providing services to the Fund, (7) transfer
agency fees and administrative reimbursements paid to the Investment Adviser or
affiliates, (8) investment management staffing, and (9) operating expenses paid
by the Funds to third parties. The Trustees also reviewed information regarding
the potential for each of the Fund and the Investment Adviser to benefit from
further economies of scale in the management of the Fund in light of reasonable
growth expectations for the Fund and certain of the Fund's expenses that are
incurred on a basis other than as a percentage of net assets.

The following summarizes factors considered by the Trustees in connection with
reviewing the information described above and their renewal of the Fund's
Management Contract. The Trustees did not identify any single factor as
all-important or controlling, and the summary does not detail all the matters
that were considered.

A.   Ancillary Benefits to Shareowners. The Trustees considered the benefits to
     shareowners of investing in a Fund that is part of a large number of
     investment companies offering a variety


38


Pioneer Europe Select Equity Fund

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


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

     of investment disciplines and providing for a large variety of Fund and
     shareowner services.

B.   Compliance and Investment Performance. The Trustees determined that the
     Investment Adviser had policies and systems reasonably designed to achieve
     compliance with the Fund's investment objective and regulatory
     requirements. The Trustees also reviewed the Fund's absolute investment
     performance based upon total return, as well as the Fund's performance
     relative to the performance of both a peer group and an index considered
     appropriate by the Independent Trustees for this purpose. The Fund's
     performance, based upon total return, was in the fifth quintile of its
     Morningstar category peer group for the 12 months ended June 30, 2006, the
     third quintile of the peer group for the three years ended June 30, 2006,
     and the second quintile for the five years ended June 30, 2006. (In all
     quintile rankings referred to throughout this discussion first quintile is
     most favorable to the Fund's shareowners. Thus, highest relative
     performance would be first quintile and lowest relative expenses also would
     be first quintile.) The Trustees, focusing on three-year total returns,
     concluded that the performance of the Fund was satisfactory.

C.   The Investment Adviser's Personnel and Methods. The Trustees reviewed the
     background of members of the team responsible for the daily management of
     the Fund and the Fund's investment objective and discipline. The
     Independent Trustees also have had discussions with senior management of
     the Investment Adviser responsible for investment operations and the senior
     management of the Investment Adviser's equities group. Among other things,
     the Trustees considered the size, education and experience of the
     Investment Adviser's investment staff and their use of technology and
     emphasis on analytics in view of the risk profile of securities in which
     the Fund invests. The Trustees concluded that the Investment Adviser had
     the quality and depth of personnel and the well-developed methods essential
     to perform its duties under the Management Contract.

D.   Nature and Quality of Other Services. The Trustees considered the nature,
     quality and extent of other services provided to shareowners of the Fund,
     including administrative and shareowner services performed by the
     Investment Adviser under the Management Contract. The Trustees also
     considered the reasonableness of the


                                                                              39

APPROVING THE MANAGEMENT CONTRACT                                  (continued)

     arrangements for reimbursement of the Investment Adviser's out-of-pocket
     costs and expenses, including overhead, for certain administrative services
     that the Investment Adviser is not required to provide under the Management
     Contract. The Trustees also considered the nature and extent of the other
     services provided by the Investment Adviser or its affiliates under other
     contracts, as well as the Investment Adviser's supervision of third party
     service providers. Based on these considerations, the Trustees concluded
     that the nature, quality and extent of such services are satisfactory and
     reliable and serve the shareowners of the Fund well.

E.   Management Fee and Expenses. The Trustees considered the Investment
     Adviser's fee under the Management Contract relative to the management fees
     charged by its Morningstar category peer group. The Fund's management fee
     for the 12 months ended June 30, 2006 was in the third quintile relative to
     the management fees paid by the other funds in that peer group for the
     comparable period. The Trustees also considered the Fund's expense ratio
     for the 12 months ended June 30, 2006 and expense ratios for the comparable
     period of the peer group of funds selected on the basis of criteria
     considered appropriate by the Independent Trustees for this purpose using
     data provided by Strategic Insight Mutual Fund Research and Consulting,
     LLC, an independent third party. The Trustees found the Fund's expense
     ratio for the 12 months ended June 30, 2006 to be in the fifth quintile,
     according to data for the applicable peer group for the most recent fiscal
     year.

F.   Profitability. The Trustees considered the level of the Investment
     Adviser's profits with respect to the management of the Pioneer Funds,
     including a review of the Investment Adviser's methodology in allocating
     certain of its costs to the management of each Fund, as well as the
     financial results realized by the Investment Adviser in connection with the
     operation of the Fund. They further considered the profits realized by the
     Investment Adviser and its affiliates from non-fund businesses that may
     benefit from or be related to the Fund's business. The Trustees considered
     the Investment Adviser's profit margins in comparison with the limited
     industry data available. The Trustees concluded that the Investment
     Adviser's profits from management of the Pioneer Funds, including the
     financial results derived from the Fund, bear a reasonable relationship to
     the services rendered and are fair for the management of the Fund.

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

G.   Economies of Scale. The Trustees considered the economies of scale with
     respect to the management of the Fund, whether the Fund had appropriately
     benefited from any economies of scale, and whether there was potential for
     realization of any further economies of scale. The Trustees concluded that
     in light of anticipated growth of the Fund, break points in the management
     fee were not necessary at this time. However, the Trustees would evaluate
     the need for break points from time to time.

H.   Other Benefits to the Investment Adviser. The Trustees also considered the
     character and amount of fees paid by the Fund, other than under the
     Management Contract, for services provided by the Investment Adviser and
     affiliates, including fees for services such as shareowner services. The
     Trustees also considered the receipt of sales loads and payments under Rule
     12b-1 plans in respect of the Pioneer Funds (including the Fund), and
     benefits to the Investment Adviser from the use of "soft" commission
     dollars to pay for research services. The Trustees further considered the
     revenues and profitability of the Investment Adviser's businesses other
     than the fund business, including the Investment Adviser's institutional
     investment advisory business. The Trustees considered the intangible
     benefits that accrue to the Investment Adviser and its affiliates by virtue
     of its relationship with the Fund and the Pioneer Funds as a group. The
     Trustees concluded that all these types of benefits accruing to the
     Investment Adviser were reasonable in the context of the overall
     relationship between the Investment Adviser and the Fund.


Conclusion. In light of the Investment Adviser's overall performance, the
Trustees considered it appropriate to continue to retain the management services
of the Investment Adviser. Based on their review of the overall nature and
quality of services provided by the Investment Adviser and the fees charged by
other funds in the Fund's relevant peer group, and taking into account all
material factors deemed relevant by the Trustees as well as the advice of
independent counsel, the Trustees concluded that the Management Contract with
the Fund, including the fee payable thereunder, was fair and reasonable and that
its renewal was in the best interests of the Fund and its shareholders.
Accordingly, the Trustees voted to approve the continuation of the Management
Contract for another year.


                                                                              41

 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.
