LETTER TO SHAREOWNERS 4/30/05
- --------------------------------------------------------------------------------

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

U.S. stocks moved higher early in 2005, with the Standard & Poor's 500 Stock
Index and the Dow Jones Industrial Average advancing to three-year highs in
early March. But from then on, soaring prices for heating oil and gasoline, plus
the steady ratcheting up of interest rates by the Federal Reserve Board
overwhelmed sentiment and caused stocks to retrace their gains. By the end of
April, the Dow Industrials, the S&P 500 and the tech-heavy NASDAQ composite were
in negative territory for the year.

With investors less welcoming of risk and the economy giving mixed signals,
value stocks were more resilient than growth stocks. In addition,
large-capitalization stocks held up better than small- and mid-sized issues that
might be more vulnerable in an economic "soft patch," in the phrase of Federal
Reserve Board Chairman Alan Greenspan.

Determined to prevent damaging inflation, the Fed has repeatedly raised
short-term interest rates. As a result, bond returns were modestly negative in
most sectors. Fixed-income investors also became more risk-averse; high-yield
and other corporate sectors retrenched after a run of stellar performance while
Treasuries and mortgage-backed securities showed small declines, with long-term
issues showing positive. Municipal revenue bonds trended higher even against a
backdrop of heavy new issuance by states and localities.

Higher U.S. interest rates enhanced the dollar's appeal and brought at least a
pause in its long, sharp drop. But the stronger dollar muted returns for U.S.
investors in overseas markets. Globally, economies rich in metals and other
industrial commodities continued to thrive on heavy demand from China and
elsewhere. Meanwhile, growth in Japan may have stalled, and Europe's expansion
moved ahead slowly.

We believe that the U.S. economy and corporate earnings will continue to grow at
a moderate pace. Oil prices have receded from their record highs, but high
energy costs and rising interest rates may be in the headlines for a while.
Looking beyond present concerns, Pioneer's global investment experts continue to
find stocks and bonds with attractive long-term potential for our domestic and
international funds.

Expanding your opportunities

This period was like all others; different classes of investments delivered
different returns. That's why allocating your portfolio across several
investment categories is one way to seek wider opportunities. Pioneer's
disciplined approach and growing range of products are designed to help you
achieve this important objective. For thoughtful guidance on how to align your
portfolio with your goals, contact your financial professional.

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

Call 1-800-225-6292 or visit www.pioneerfunds.com for the most recent month-end
performance results. Current performance may be lower or higher than the
performance data quoted.

The performance data quoted represents past performance, which is no guarantee
of future results. Investment return and principal value will fluctuate, and
shares, when redeemed, may be worth more or less than their original cost.

POP returns reflect deduction of maximum 5.75% sales charge. NAV results
represent the percent change in net asset value per share. Returns would have
been lower had sales charges been reflected. All results are historical and
assume the reinvestment of dividends and capital gains. Other share classes are
available for which performance and expenses will differ.

The Fund will charge a 2% redemption fee on proceeds from shares redeemed or
exchanged within 30 days of acquiring (either by purchasing or exchanging) Fund
shares. See the prospectus for complete details.

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 performance table and graph do not reflect the deduction of 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.

"If redeemed" returns reflect the deduction of applicable contingent deferred
sales charge (CSDC). Effective December 1, 2004, the period during which a CDSC
is applied to withdrawals was shortened to 5 years. The maximum CDSC for class B
shares continues to be 4%. For more complete information, please see the
prospectus for details. "If Held" results represent the percent change in net
asset value per share. Returns would have been lower had sales charges been
reflected. Note: Shares purchased prior to December 1, 2004 remain subject to
the CDSC in effect at the time you purchased those shares. For performance
information for shares purchased prior to December 1, 2004, please visit

Class C shares held for less than one year are also subject to a 1% contingent
deferred sales charge (CDSC). The performance of Class C shares does not reflect
the 1% front-end sales charge in effect prior to February 1, 2004. If you paid a
1% sales charge, your returns would be lower than those shown above. "If Held"
results represent the percent change in net asset value per share. Returns would
have been lower had sales charges been reflected. All results are historical and
assume the reinvestment of dividends and capital gains. Other share classes are

The Fund will charge a 2% redemption fee on proceeds from shares redeemed or
exchanged within 30 days of acquiring (either by purchasing or exchanging) Fund
shares. See the prospectus for complete details.

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

COMPARING ONGOING FUND EXPENSES
- --------------------------------------------------------------------------------

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

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

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

This example is intended to help you understand your ongoing expenses (in
dollars) of investing in the Fund and to compare these costs with the ongoing
costs of investing in other mutual funds. The example is based on an investment
of $1,000 at the beginning of the Fund's latest six-month period and held
throughout the six months.

Using the Tables

Actual Expenses

The first table below provides information about actual account values and
actual expenses. You may use the information in this table, together with the
amount you invested, to estimate the expenses that you paid over the period as
follows:

1.   Divide your account value by $1,000
     Example: an $8,600 account value [divided by] $1,000 = 8.6

2.   Multiply the result in (1) above by the corresponding share class's number
     in the third row under the heading entitled "Expenses Paid During Period"
     to estimate the expenses you paid on your account during this period.

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.

PORTFOLIO MANAGEMENT DISCUSSION 4/30/05
- --------------------------------------------------------------------------------

European stocks moved higher during the first half of Pioneer Europe Fund's
fiscal year, supported in large part by the positive global economic backdrop.
Stocks in the diversified financials and health care sectors were particularly
influential, which Stan Pearson, who is responsible for the day-to-day
management of the Fund, highlights in the discussion below.

Q:   How did the Fund perform during the first half of its fiscal year?

A:   For the six months ended April 30, 2005, the Fund's Class A shares returned
     7.57% at net asset value. Favorable as those results were, they lagged the
     Fund's benchmark, the Morgan Stanley Capital International (MSCI) Europe
     Index, which posted a return of 9.55%, and its Lipper category of 113
     European Funds, which posted an average return of 10.14% for the same
     period.

     Bank holdings, particularly Royal Bank of Scotland and BNP Paribas, were a
     major factor in the Fund's underperformance relative to its benchmark and
     its peer group. Investments in Royal Bank of Scotland, the Fund's third
     largest holding on April 30, underperformed as a result of investor
     concerns about a potential slowdown in consumer spending and the housing
     market in the United Kingdom. A slowdown could translate into reduced
     consumer demand for loans. It was also feared that slower growth could
     impact consumer credit quality and force the bank to make higher provisions
     for bad debts going forward. Similarly, concerns over sluggish growth in
     the Euro zone negatively affected the performance of BNP Paribas (France).

     We continue to hold both stocks, because we believe the companies still
     offer strong growth potential and have attractive price valuations
     supported by high dividend yields. In addition, Royal Bank of Scotland and
     BNP Paribas are benefiting from their diversified businesses - retail,
     corporate, and investment banking, which are spread across regions, thereby
     creating strong capital positions and a more solid earnings mix. With its
     positive cash-flow position, BNP has initiated a share buy-back program.

     principal value will fluctuate, and shares, when redeemed, may be worth
     more or less than their original cost.

Q:   Which stocks contributed to the Fund's performance?

A:   While some banking stocks proved disappointing during the six months ended
     April 30, 2005 an overweight position and effective stock selection in the
     diversified financials sector proved positive. Deutsche Boerse (Germany)
     was a positive contributor. During the first quarter of 2005, the stock
     recovered strongly after withdrawing its bid for the London Stock Exchange.
     We sold the entire position in the company towards the end of the period to
     profit from the price appreciation.

     Stock selection in the health care equipment and services sector was also
     positive over the six months. The pharmaceutical wholesaler Celesio
     (Germany) performed very well, and we sold the position to realize profits
     in December. Healthcare-equipment manufacturer Fresenius AG (Germany)
     posted results that exceeded market expectations. We believe the stock is
     attractively valued and offers upside potential on the back of improving
     results and relatively strong growth opportunities for the sector.

     Our underweight position and successful stock selection in the technology
     hardware sector also were positive contributors. With the sector
     underperforming the market for the six months under review, our decision to
     limit the Fund's exposure proved wise. The technology sector underperformed
     the market on the back of investor concerns over the sector's earnings
     outlook as investment spending by companies remains subdued. We added
     Ericsson (Sweden) to the portfolio, which outperformed for the six months
     ended April 30, and decided against owning the French stock Alcatel, which
     was favorable, since the stock lost ground for the six-month period.
     Ericsson, which is undervalued in our opinion, is the top
     telecommunications equipment producer for mobile phones and should benefit
     with the transition from second to third generation mobile telephony in
     Europe. Lastly, the Fund's energy exposure contributed at times during the
     period, but was neutral overall for the six months.

Q:   Did you add any new holdings to the portfolio?

A:   We found several new investment opportunities. In the automobile sector, we
     added Continental (Germany) based on its compelling price valuation and our
     expectation that the company will increase earnings as its new car safety
     system, the Electronic Stability

     Program penetrates the U.S. market. Synthes (Switzerland), which develops
     and produces medical products for orthopedic surgery, is well positioned to
     benefit from a growing market. We think Swiss Re (Switzerland), a
     reinsurance company, offers an attractive growth opportunity. The outlook
     for the stock is supported by our view that the reinsurance cycle appears
     relatively stable at this time. We favor Telekom Austria, as the company is
     creating attractive growth opportunities in Eastern Europe.

     Among the Fund's holdings sold were HSBC Holding (U.K.), Fortis (Benelux)
     and Assicurazioni Generali (Italy), because the stocks had reached the
     price targets set by the portfolio management team.

Q:   What is your outlook?

A:   The European economy appears set to grow at a very modest pace, with gross
     domestic product expected to be around 1.6% during 2005. However, while
     unemployment remains high and inflation appears under control, the European
     Central Bank is likely to keep interest rates low. The low borrowing cost
     is good news, but we are not expecting to see any major acceleration in the
     economic cycle during the rest of the year. The dividend yield in the
     European equity market is high at around 3.0%, offering valuation support,
     even if growth is low.

     We believe European markets will continue to move in a positive direction
     and will be characterized by steady but modest returns. Stock price
     valuations are quite reasonable, particularly in comparison to the low
     interest rate environment and the lower return available from government
     bonds. Our primary focus will remain on stocks that we consider to be
     attractive in terms of valuation and risk.


Investing in foreign and/or emerging markets securities involves risks relating
to interest rates, currency exchange rates, economic, and political conditions.
The portfolio may invest a substantial amount of its assets in issuers located
in a limited number of countries and therefore is more susceptible to adverse
economic, political, or regulatory developments affecting those countries. These
risks may increase share price volatility.


                                                                              13

NOTES TO FINANCIAL STATEMENTS 4/30/05 (unaudited)
- --------------------------------------------------------------------------------

1. Organization and Significant Accounting Policies

Pioneer Europe 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 to seek long-term
growth of capital.

The Fund offers five classes of shares - Class A, Class B, Class C, Class R and
Class Y shares. Each class of shares represents an interest in the same
portfolio of investments of the Fund and has equal rights to voting,
redemptions, dividends and liquidation, except that each class of shares can
bear different transfer agent and distribution fees and 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
income, expenses and gains and losses on investments during the reporting year.
Actual results could differ from those estimates. The following is a summary of
significant accounting policies followed by the Fund in the preparation of its
financial statements, which are consistent with those policies generally
accepted in the investment company industry:

A.   Security Valuation

     Security transactions are recorded as of trade date. The net asset value of
     the Fund is computed once daily, on each day the New York Stock Exchange
     (NYSE) is open, as of the close of regular trading on the NYSE. In
     computing the net asset value, securities are valued using the last sale
     price on the principal exchange where they are traded. Securities that have
     not traded on the date of valuation, or securities for which sale prices
     are not generally reported, are valued using the mean between the last bid
     and asked prices. Securities for which market quotations are not readily
     available are valued at their fair values as determined by, or under the
     direction of, the Board of Trustees. The Fund invests primarily in
     securities of non-U.S. issuers. The principal exchanges and


                                                                              29


Pioneer Europe Fund

- --------------------------------------------------------------------------------
NOTES TO FINANCIAL STATEMENTS 4/30/05 (unaudited)                    (continued)
- --------------------------------------------------------------------------------

     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 from foreign securities where the ex-dividend date may have
     passed are recorded as soon as the Fund becomes aware of the ex-dividend
     data in the exercise of reasonable diligence. Interest income is recorded
     on the accrual basis. Dividend and interest income are reported 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 represent,
     among other things, the net realized gains and losses on foreign currency
     contracts, disposition of foreign currencies and the difference between the
     amount of income accrued and the U.S. dollars actually received. Further,
     the effects of changes in foreign currency exchange rates on investments
     are not segregated in the statement of operations from the effects of
     changes in market price of those securities but are included with the net
     realized and unrealized gain or loss on investments.

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

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

C.   Forward Foreign Currency Contracts

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

     At April 30, 2005, the Fund had no outstanding portfolio hedges. The Fund's
     gross forward currency settlement hedges receivable and payable were
     $957,791 and $964,449, respectively, resulting in a net payable of $6,658.

D.   Futures Contracts

     The Fund may enter into futures transactions to hedge against changes in
     interest rates, securities prices and currency rates or to seek to increase
     total return. Upon entering into a futures contract, the Fund is required
     to deposit with a broker an amount of cash or securities equal to the
     minimum "initial margin" requirements of the associated futures exchange.
     Subsequent payments for futures contracts ("variation margin") are paid or
     received by the Fund, depending on the daily fluctuation in the value of
     the contracts, and are recorded by the Fund as unrealized gains or losses.
     When the contract is closed, the Fund realizes a gain or loss equal to the
     difference between the opening and closing value of the contract. The use
     of futures contracts involves, to varying degrees, elements of market and
     counterparty risks which may exceed the amounts recognized by the Fund.
     Changes in value of the contracts may not directly correlate to the changes
     in value of the underlying securities. These risks may decrease the
     effectiveness of the Fund's hedging strategies and potentially result in a
     loss. As of April 30, 2005, the Fund had no open futures contracts.


                                                                              31

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

E.   Federal Income Taxes

     It is the Fund's policy to comply with the requirements of the Internal
     Revenue Code applicable to regulated investment companies and to distribute
     all of its taxable income and net realized capital gains, if any, to its
     shareowners. Therefore, no federal income tax provision is required.

     The amounts and characterizations of distributions to shareowners for
     financial reporting purposes are determined in accordance with federal
     income tax rules. Therefore, the sources of the Fund'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 October 31, 2004, the Fund had a net capital loss carryforward of
     $58,015,667, of which the following amounts will expire between 2009 and
     2011 if not utilized: $20,588,660 in 2009, $23,790,437 in 2010 and
     $13,636,570 in 2011.

     There were no distributions paid during the fiscal year ended October 31,
     2003. The tax character of distributions paid during the year ended October
     31, 2004 was as follows:

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


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

F.   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 $9,286 in underwriting commissions on the
     sale of Class A shares during the six months ended April 30, 2005.

G.   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 the respective percentage of adjusted net
     assets at the beginning of the day.

     Distributions to shareowners are recorded as of the ex-dividend date.
     Distributions paid by the Fund with respect to each class of shares are
     calculated in the same manner, at the same time and in the same amount,
     except that Class A, Class B, Class C,


                                                                              33


Pioneer Europe Fund

- --------------------------------------------------------------------------------
NOTES TO FINANCIAL STATEMENTS 4/30/05 (unaudited)                    (continued)
- --------------------------------------------------------------------------------

     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 Fund's portfolio. Management fees are
calculated daily at the annual rate of 1.00% of the Fund's average daily net
assets up to $300 million; 0.85% of the next $200 million; and 0.75% of the
excess over $500 million.

In addition, under the management and administration agreements, certain other
services and costs, including accounting, regulatory reporting and insurance
premiums, are paid by the Fund. At April 30, 2005, $164,939 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 $135,412 in transfer agent
fees payable to PIMSS at April 30, 2005.

4. Distribution and Service Plans

The Fund adopted Plans of Distribution with respect to 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 of 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 $74,923 in distribution fees payable to PFD at
April 30, 2005. The Fund also has 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 (except Class Y shares) may be
subject to a contingent deferred sales charge (CDSC). Effective February 1,
2004, a CDSC of 1.00% may be imposed on redemptions of certain net asset value
purchases of Class A shares within 18 months of purchase (12 months for shares
purchased prior to February 1, 2004). Class B shares subscribed on or after
December 1, 2004 that are redeemed within five years of purchase are subject to
a CDSC at declining rates beginning at 4.00%, based on the lower of cost or
market value of shares being redeemed. Redemptions of Class C shares within one
year of purchase are subject to a CDSC of 1.00%. Redemptions of Class R shares
within 18 months of purchase were subject to a CDSC of 1.00%. Effective July 1,
2004, the CDSC on Class R shares was eliminated. Proceeds from the CDSCs are
paid to PFD. For the six months ended April 30, 2005, CDSCs in the amount of
$24,154 were paid to PFD.

The Fund charges a 2.0% redemption fee on shares sold within 30 days of
purchase. For Class A, R and Y shares this fee became effective November 1,
2003, while for Class B and C shares, this fee became effective July 1, 2004.
The fee does not apply to certain types of transactions as described in the
Fund's prospectus. For the six months ended April 30, 2005, the Fund collected
$8,936 in redemption fees, which are included in the Fund's capital account.

5. Expense Offsets

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 April 30, 2005, the Fund's expenses
were reduced by $5,259 under such arrangements.

6. Line of Credit Facility

Funds), collectively participate in a $50 million committed, unsecured revolving
line of credit facility. Borrowings are used solely


                                                                              35

for temporary or emergency purposes. The Fund may borrow up to the lesser of $50
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 April 30, 2005, the Fund had no borrowings
under this agreement.

7. Additional Information

The Fund's Board of Trustees have approved the merger of the Pioneer Europe
Select Fund into the Fund. The plans include renaming the merged entity the
Pioneer Europe Select Equity Fund. This transaction is subject to the approval
of the shareholders of the Pioneer Europe Select Fund in 2005. There can be no
assurance that this transaction will be completed.

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

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

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

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


                                                                              37

CONTRACT                                                             (continued)
- --------------------------------------------------------------------------------

of Ethics and the structure and responsibilities of the Investment Adviser's
compliance department, (viii) the nature, cost and character of non-investment
management services provided by the Investment Adviser and its affiliates and
(ix) the disclosures included in the Fund's prospectuses and reports to
shareholders.

Specifically in connection with the Independent Trustees' review of the
Management Contract, the Independent Trustees requested and the Investment
Adviser provided additional information in order to evaluate the quality of the
Investment Adviser's services and the reasonableness of the fee under the
Management Contract. Among other items, this information included data or
analyses of (1) investment performance for one, three and five-year periods
ended June 30, 2004 for the Fund and a peer group selected by the Independent
Trustees for this purpose, (2) management fees incurred by a peer group of funds
selected by the Independent Trustees for this purpose, (3) the advisory fees of
comparable portfolios of other clients of the Investment Adviser, (4) expense
ratios for the Fund and a peer group of funds selected by the Independent
Trustees for this purpose, (5) the overall organization of the Investment
Adviser, (6) the Investment Adviser's financial results and condition, including
its and certain of its affiliates profitability from services performed for the
Fund, (7) transfer agency fees and administrative reimbursements paid to the
Investment Adviser or affiliates, (8) investment management staffing, and (9)
operating expenses paid to third parties. The Trustees also reviewed information
regarding the potential for the Fund and the Investment Adviser to benefit from
further economies of scale in the management of the Fund in light of reasonable
growth expectations for the Fund and certain of the Fund's expenses that are not
incurred as fees based on a percentage of net assets.

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

A.   Ancillary Benefits to Shareholders. The Trustees considered the benefits to
     shareholders of investing in a Fund that is part of a large number of
     investment companies offering a variety of investment disciplines and
     providing for a large variety of Fund and shareholder services.

B.   Compliance and Investment Performance. The Trustees determined that the
     Investment Adviser had policies and systems reasonably designed to achieve
     compliance with the Fund's investment objective and regulatory
     requirements. The Trustees also reviewed the Fund's investment performance,
     as well as the Fund's performance based upon total return compared to both
     the performance of a peer group and the results of two indices, in each
     case selected by the Independent Trustees for this purpose. The Fund's
     performance based on total return was in the third quintile of the peer
     group for the 12 months ended June 30, 2004, in the third quintile for the
     three years ended June 30, 2004 and in the fifth quintile for the five
     years ended June 30, 2004. (In all quintile rankings referred to throughout
     this discussion first quintile is most favorable to the Fund's
     shareholders. Thus, highest relative performance would be first quintile
     and lowest relative expenses also would be first quintile.) The Trustees
     concluded that the performance of the Fund supported the continuation of
     the Management Contract.

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

D.   Nature and Quality of Other Services. The Trustees considered the nature,
     quality, cost and extent of other services provided to shareholders of the
     Fund, including administrative and shareholder services performed by the
     Investment Adviser under the Management Contract. The Trustees also
     considered the reasonableness of the arrangements for reimbursement of the
     Investment Adviser's out-of-pocket costs and expenses, including overhead,
     for certain administrative services that the Investment Adviser is


                                                                              39

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

     not required to provide under the Management Contract. The Trustees also
     considered the nature and extent of the other services provided by the
     Investment Adviser's affiliates under other contracts and its supervision
     of third party service providers. Based on these considerations, the
     Trustees concluded that the nature, quality, cost and extent of such
     services are satisfactory and reliable and serve the shareholders of the
     Fund well.

E.   Management Fee and Expenses. The Trustees considered the Investment
     Adviser's fee under the Management Contract relative to the management fees
     charged by a peer group of funds selected by the Independent Trustees for
     this purpose using data provided by an independent third party. The Fund's
     management fee for the 12 months ended June 30, 2004 was in the fourth
     quintile relative to the management fees paid by the other funds in that
     peer group for the comparable period. The Trustees determined that the fee
     under the Management Contract was reasonable and fair in light of both the
     overall nature and quality of services provided by the Investment Advisor
     and the fees charged by the funds in the peer group. The Trustees also
     considered the Fund's expense ratio (both before and after giving effect to
     expense limitations) for the 12 months ended June 30, 2004 and expense
     ratios for the comparable period of a peer group of funds selected by the
     Independent Trustees for this purpose. The Fund's expense ratio was in the
     third quintile of this peer group for the most recent fiscal year. The
     Trustees concluded that the Fund's overall expense ratio was reasonable
     compared to that of most of the comparable funds.

F.   Profitability. The Trustees considered the level of the Investment
     Adviser's profits with respect to the management of the Pioneer Funds,
     including details with respect to the Fund. This consideration included a
     review of the Investment Adviser's methodology in allocating certain of its
     costs to the management of each Fund. The Trustees also considered the
     financial results realized by the Investment Adviser in connection with the
     operation of the Fund. They further considered the profits realized by the
     Investment Adviser and its affiliates from non-fund businesses that may
     benefit from or be related to the Fund's business. The Trustees considered
     the Investment Adviser's profit margins in comparison with the limited
     available industry data. The Trustees concluded that the Investment
     Adviser's profits from management of the


40


Pioneer Europe Fund

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

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

     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 whether the Fund has
     appropriately benefited from any economies of scale, and whether there was
     potential for realization of any further economies of scale. Because of
     break points in the management fee, the Trustees concluded that any
     perceived or potential economies of scale would be shared at future asset
     levels in a reasonable manner as the Fund grows in size between the Fund's
     shareholders and the Investment Advisor.

H.   Other Benefits to the Investment Adviser. The Trustees also considered the
     character and amount of fees paid by the Fund, other than under the
     Management Contract, for services provided by the Investment Adviser and
     affiliates, including fees for services such as shareholder services. The
     Trustees also considered the receipt of sales loads and payments under Rule
     12b-1 plans in respect to the Pioneer Funds (including the Fund), and
     benefits to the Investment Adviser from the use of "soft" commission
     dollars to pay for research and brokerage 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. The Trustees, in light of the Investment Adviser's overall
performance, considered it appropriate to continue to retain the management
services of the Investment Adviser. Based on their evaluation of all material
factors deemed relevant and the advice of independent counsel, the Trustees
concluded that the Management Contract with the Fund is fair and reasonable and
voted to approve the continuation of the Management Contract for another year.


                                                                              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.

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

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

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

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


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

    N/A

(f) If greater than 50 percent, disclose the percentage of hours expended on the
principal accountant's engagement to audit the registrant's financial statements
for the most recent fiscal year that were attributed to work performed by
persons other than the principal accountant's full-time, permanent employees.

N/A

(g) Disclose the aggregate non-audit fees billed by the registrant's accountant
for services rendered to the registrant, and rendered to the registrant's
investment adviser (not including any sub-adviser whose role is primarily
portfolio management and is subcontracted with or overseen by another investment
adviser), and any entity controlling, controlled by, or under common control
with the adviser that provides ongoing services to the registrant for each of
the last two fiscal years of the registrant.

The Fund's independent auditor, Ernst & Young
LLP ("E&Y"), has advised the Securities
and Exchange Commission, the Public Company
Accounting Oversight Board, and the Audit
Committee of the Fund's Board of Trustees that
certain non-audit work performed by E&Y's China
affiliate raised questions regarding E&Y's
independence with respect to its performance of
audit services for the Fund.  In July 2004, E&Y
became aware that member firms in China ("E&Y
China") provided certain tax services to offices of
UniCredito Italiano, S.p.A. ("UCI"), a member of
the Fund's Investment Company Complex.  The
services included receipt and disbursement of
monies transferred to E&Y China by UCI in
payment of individual expatriate income taxes due
on returns prepared by E&Y China for certain UCI
employees located in China from October 1998 to
May 2003.  E&Y became auditors of the Fund in
May 2002.  These expatriate tax services were
discontinued in May 2003.  The fees received by
E&Y China for all such services totaled $3,685.

The Fund's Audit Committee and E&Y have
discussed the matter, including the nature of the
services provided, the personnel involved in
providing the services and the fees received by
E&Y for performing the services.  E&Y has informed
the Audit Committee that based on its internal reviews
and the de minimis nature of the services provided and
fees received, it does not believe its independence
with respect to the Fund has been impaired.

N/A


(h) Disclose whether the registrant's audit committee of the board of trustees
has considered whether the provision of non-audit services that were rendered to
the registrant's investment adviser (not including any subadviser whose role is
primarily portfolio management and is subcontracted with or overseen by another
investment adviser), and any entity controlling, controlled by, or under common
control with the investment adviser that provides ongoing services to the
registrant that were not pre-approved pursuant to paragraph (c)(7)(ii) of
Rule 2-01 of Regulation S-X is compatible with maintaining the principal
accountant's independence.
