President's Letter

Dear Shareowner,

Stock and bond markets around the globe have been experiencing one of their
most tumultuous periods in history. Investors have witnessed volatility of a
magnitude that many have never before seen. Distance often provides the best
vantage point for perspective. Still, we believe that the benefits of basic
investment principles that have stood the test of time -- even in the midst of
market turmoil -- cannot be underestimated.

First, invest for the long term. The founder of Pioneer Investments, Philip L.
Carret, began his investment career during the 1920s. One lesson he learned is
that while great prosperity affords an advantageous time for selling stocks,
extreme economic slumps can create opportunities for purchase. Indeed, many of
our portfolio managers, who follow the value-conscious investing approach of
our founder, are looking at recent market conditions as an opportunity to buy
companies whose shares we believe have been unjustifiably beaten down by
indiscriminate selling, but that we have identified as having strong prospects
over time. While investors may be facing a sustained market downturn, we
continue to believe that patience, along with staying invested in the market,
are important considerations for long-term investors.

A second principle is to stay diversified across different types of
investments. The global scope of the current market weakness poses challenges
for this basic investment axiom. But the turbulence makes now a good time to
reassess your portfolio and make sure that your investments continue to meet
your needs. We believe you should work closely with your financial advisor to
find the mix of stocks, bonds and money market assets that is best aligned to
your particular risk tolerance and investment objective.

As the investment markets sort through the continuing crisis in the financial
industry, we are staying focused on the fundamentals and risk management. With
more than 80 years of experience behind us, we have learned how to navigate
turbulent markets. At Pioneer Investments, risk management has always been a
critical part of our culture -- not just during periods of extraordinary
volatility. Our investment process is based on fundamental research,
quantitative analysis and active portfolio management. This three-pillared
process, which we apply to each of our portfolios, is supported by an
integrated team approach and is designed to carefully balance risk and reward.
While we

2    Pioneer Europe Select Equity Fund | Semiannual Report | 2/28/09


see potential chances for making money in many corners of the market, it takes
research and experience to separate solid investment opportunities from
speculation.

We invite you to learn more about Pioneer and our time-tested approach to
investing by consulting with your financial advisor or visiting us online at
www.pioneerinvestments.com. Thank you for investing with Pioneer.

Sincerely,

/s/ Daniel K. Kingsbury

            Pioneer Europe Select Equity Fund | Semiannual Report | 2/28/09    3


Portfolio Management Discussion | 2/28/09

Investors in the European equity markets suffered substantial losses during the
six months ended February 28, 2009. Prices of virtually all stocks declined
steeply in the face of mounting evidence of a slowing global economy and
falling corporate profitability. In the following discussion, Andrew Arbuthnott
reviews the factors that affected the performance of Pioneer Europe Select
Equity Fund during the six months. Mr. Arbuthnott, head of the Core European
Equities Group of Pioneer Investments in Dublin, Ireland, is a member of the
team responsible for the Fund's day-to-day management.

Q  How did Pioneer Europe Select Equity Fund perform during the six months ended
   February 28, 2009?

A  Europe Select Equity Fund's Class A shares returned -42.20%, at net asset
   value, for the six months ended February 28, 2009, compared with a return
   of -47.53% during the same period for the Fund's benchmark, the Morgan
   Stanley Capital International (MSCI) Europe Index. Over the same six
   months, the average return of the 114 mutual funds in Lipper's European
   Region Funds category was -46.69%.

Q  What were market conditions like in Europe during the six months ended
   February 28, 2009?

A  It was a very difficult time for the European equity markets, with stocks in
   all sectors recording major price losses. Investors lost confidence as a
   confluence of negative economic news raised fears that the global economy
   was dipping into recession. Economic growth slackened, liquidity in the
   financial markets deteriorated, financial institutions struggled to find
   sufficient capital, and corporate profits declined while commodity prices
   went through wide swings before falling sharply. International currency
   exchange rates also fluctuated significantly. The problems were felt most
   severely in the financials sector, especially after the U.S. investment
   bank Lehman Brothers declared bankruptcy in September of 2008. At the start
   of the period, in August of 2008, the situation in Europe was not helped
   when the European Central Bank (ECB) opted to maintain its tight monetary
   policies, as it focused more on preventing inflation than on re-stimulating
   economic growth. Later, the ECB began to lower short-term rates, but it
   acted more slowly than other major central banks in trying to increase
   liquidity and stimulate economic growth.

   Credit was in short supply, and financials stocks -- especially bank stocks
   -- were particularly hard hit, with the average European banking stock

4    Pioneer Europe Select Equity Fund | Semiannual Report | 2/28/09


   declining by 68% over the six-month period (in U.S. dollar terms).
   Diversified financial companies, including investment banks, performed
   almost as poorly during the six months ended February 28, 2009, declining
   by 65% on average. Other poor-performing industry groups included:
   semiconductors and materials (-60% each); insurance, technology hardware
   and transportation (-55% each); and capital goods stocks, which declined by
   an average of 52%.

   The better-performing groups were in the traditionally defensive areas of
   the market, but even they suffered severe price losses during the six
   months ended February 28, 2009. Retailers, telecommunication services and
   retailers for food and staples all were down by about 29%. Food, beverage
   and tobacco stocks lost 30% on average, as did household and personal care
   products stocks. Pharmaceutical stocks declined by an average of 32%, while
   health care equipment and services stocks fell by an average 34%, and media
   stocks declined by 36%.

Q  How was the Fund's portfolio positioned in this environment, and how did that
   affect its investment results over the six months ended February 28, 2009?

A  The Europe Select Equity Fund's return was disappointing, consistent with the
   overall trend in the markets, but the Fund nevertheless managed to
   outperform its benchmark, the MSCI Europe Index, and its Lipper peer group
   average over the six months. The Fund's sector and industry weightings
   tended to contribute to its relative performance advantage, especially a
   notable underweighting of financials stocks. The Fund had only one
   insurance company investment, for example. That was the German reinsurance
   company Munich Re, which outperformed the overall financials sector even
   though its share price fell. Similarly, the Fund owned only one diversified
   financials stock, the investment banking and asset management firm Credit
   Suisse, which performed in line with the overall MSCI Europe Index. The
   Fund had no exposure to such poor-performers as UBS, Deutsche Bank and
   Fortis. Similarly, we underweighted the Fund in bank stocks, which also
   helped. While the Fund's bank holdings did not do well, our decisions not
   to own any banks based in the United Kingdom, Spain, Italy or Ireland
   limited the Fund's exposure to the worst-performing areas in the markets.
   However, the Fund's investments in the French banking firms BNP Paribas and
   Societe Generale performed poorly, consistent with the overall industry.

   Overall stock selection was good for the Fund on a relative basis, although
   absolute results also were disappointing. The Fund was overweight in
   capital goods companies, but we generally avoided the worst performing
   industrial stocks, placing a greater focus on defense-oriented companies
   that were more resilient to overall economic trends. The Fund's investment
   in Thales, a French aerospace corporation, fell in value, but it still
   outperformed the

            Pioneer Europe Select Equity Fund | Semiannual Report | 2/28/09    5


   general capital goods group. On the positive side, we initiated a position
   for the Fund in Finmeccanica, an Italian aerospace and security firm, in
   October 2008. The holding subsequently gained in value, rising by 11%
   through the end of the period on February 28, 2009. One capital goods
   company that did not help the Fund, however, was Siemens, the global
   engineering and electronics firm based in Munich, Germany. We still favor
   the company, however, as it is going through a restructuring under new
   management that we think may eventually lead to improved performance.

   The Fund also had good relative performance from stock selections in the
   materials and the health care equipment and services industries. In
   materials, the Fund owned a position in the Ireland-based global building
   supplies company CRH. Its global reach, strong balance sheet and
   diversified operations helped it do well in a very poor market. Its share
   price declined by about 20%, but its industry average fell 60%. Among the
   Fund's health care equipment and services holdings, Fresenius Medical Care
   was an outperformer. This German company, as the world's leading operator
   of dialysis care centers for the treatment of patients with serious kidney
   problems, is less susceptible to economic conditions than most stocks. In
   the food, beverage and tobacco industry, the Fund saw relatively good
   results from British American Tobacco, a tobacco products company based in
   the United Kingdom, and from ABInBev, the Belgian brewing company. Its
   share price rose by 45% after it completed the acquisition of Anheuser
   Busch in the United States during the period. In the utilities industry, we
   generally stayed away from any companies exposed to commodity prices. The
   Fund's investment in National Grid, an electricity and natural gas
   transmission company based in the United Kingdom, helped support relative
   results even though its share price declined by 20%. The Fund had no
   exposure at all to the technology hardware industry, which proved to be an
   advantage during a difficult six- month period.

Q  What types of disappointments detracted from results?

A  Stock selections in the transportation industry tended to be disappointing.
   Two particularly poor-performing holdings were TNT of the Netherlands and
   Deutsche Post of Germany. The companies operate the postal services in
   their respective countries and both also operate international express
   package delivery services. We underestimated the vulnerability of the
   package delivery services to the economic downturn, as both companies
   performed very poorly. The Fund's positions in the energy sector also did
   not provide good results. Oil field services companies such as Technip of
   France and Repsol of Spain performed very poorly as the price of oil fell
   sharply during the six months ended February 28, 2009, after peaking early
   in the summer of 2008. In addition, the Fund's underweighting of
   telecommunication services companies, which as a group outperformed the
   MSCI

6    Pioneer Europe Select Equity Fund | Semiannual Report | 2/28/09


   Europe Index, did not help. Moreover, one telecom holding in the Fund,
   Tele2 of Sweden, underperformed because of its exposure to the troubled
   economy of Russia. The Fund had no positions in companies such as France
   Telecom and Deutsche Telecom, which tended to hold up relatively well.

Q  What is your investment outlook?

A  We think we are beginning to see some positive developments that should
   eventually contribute to improved market conditions. European monetary
   policy has eased and interest rates have declined, which should improve
   liquidity in the markets, while the value of the euro has fallen in
   international currency markets, making European goods more competitive in
   price. At the same time, commodity prices have fallen and inflation risks
   appear to be slight.

   Although European stocks performed poorly over the past six months ended
   February 28, 2009, we believe many solid European corporations are selling
   at attractive prices and should have reasonable chances to perform well
   when market conditions improve. Nevertheless, we anticipate the European
   equity markets may continue to be sluggish until there is stronger evidence
   of stabilization of the global economy and capital markets.

Please refer to the Schedule of Investments on pages 16-19 for a full listing
of fund securities.

Investing in foreign and/or emerging markets securities involves certain risks,
including risks relating to interest rates, currency exchange rates, economic,
and political conditions. The Fund may invest a substantial amount of its
assets in issuers located in a limited number of countries and, therefore, is
susceptible to adverse economic, political or regulatory developments affecting
those countries. The Fund invests in a limited number of securities and, as a
result, the Fund's performance may be more volatile than the performance of
funds holding more securities. At times, the Fund's investments may represent
industries or industry sectors that are interrelated or have common risks,
making it more susceptible to any economic, political, or regulatory
developments or other risks affecting those industries and sectors.

Past performance is no guarantee of future results, and there is no guarantee
that market forecasts discussed will be realized.

Any information in this shareholder report regarding market or economic trends
or the factors influencing the Fund's historical or future performance are
statements of the opinion of Fund management as of the date of this report.
These statements should not be relied upon for any other purposes.

Note to Shareholders: The Board of Trustees has approved the reorganization of
the Fund into Pioneer Global Equity Fund (formerly, Pioneer Global Select
Equity Fund). The reorganization, which does not require shareholder approval,
is expected to qualify as a tax-free reorganization and to be completed on or
about June 12, 2009.

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 1/1/12 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.

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. Note: Shares purchased prior to December 1, 2004 remain subject to
the CDSC in effect at the time you purchased those shares. For performance

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.

Class Y shares are not subject to sales charges and are available for limited
groups of eligible investors, including institutional investors. All results
are historical and assume the reinvestment of dividends and capital gains.
Other share classes are available for which performance and expenses will
differ.

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. The predecessor fund did not offer Class Y
shares. Returns prior to June 24, 2005 are based on the net asset value
performance of the predecessor fund's Class A shares, which has not been
restated to reflect any differences in expenses, including Rule 12b-1 fees
applicable to Class A shares.

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 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.

*  Expenses are equal to the Fund's annualized expense ratio of 1.50%, 2.39%,
   2.39% and 1.18%, for Class A, Class B, Class C and Class Y shares,
   respectively, multiplied by the average account value over the period,
   multiplied by 181/365 (to reflect the one-half year period).

Hypothetical Example for Comparison Purposes

The table below provides information about hypothetical account values and
hypothetical expenses based on the Fund's actual expense ratio and an assumed
rate of return of 5% per year before expenses, which is not the Fund's actual
return. The hypothetical account values and expenses may not be used to
estimate the actual ending account balance or expenses you paid for the period.

You may use this information to compare the ongoing costs of investing in the
Fund and other funds. To do so, compare this 5% hypothetical example with the
5% hypothetical examples that appear in the shareholder reports of the other
funds.

Please note that the expenses shown in the tables are meant to highlight your
ongoing costs only and do not reflect any transaction costs, such as sales
charges (loads) that are charged at the time of the transaction. Therefore, the
table below is useful in comparing ongoing costs only and will not help you
determine the relative total costs of owning different funds. In addition, if
these transaction costs were included, your costs would have been higher.

1. Organization and Significant Accounting Policies

Pioneer Europe Select Equity Fund (the Fund) is the sole portfolio comprising
Pioneer Series Trust IX, a Delaware statutory trust registered under the
Investment Company Act of 1940 as a diversified, open-end management investment
company. The investment objective of the Fund is long-term growth of capital.

The Fund offers four classes of shares -- Class A, Class B, Class C, and Class
Y shares. Class A, Class B and Class C Shares were first publicly offered on
December 29, 2000. Class Y shares were first publicly offered on June 24, 2005.
Each class of shares represents an interest in the same portfolio of
investments of the Fund and has identical rights (based on relative net asset
values) to assets and liquidation proceeds. Share classes can bear different
class-specific fees and expenses such as transfer agent and distribution fees.
Differences in class-specific fees and expenses will result in differences in
net investment income and, therefore, the payment of different dividends by
each class. The Amended and Restated Declaration of Trust of the Fund gives the
Board the flexibility to specify either per share voting or dollar-weighted
voting when submitting matters for shareholder approval. Under per share
voting, each share of a class of the Fund is entitled to one vote. Under
dollar-weighted voting, a shareholder's voting power is determined not by the
number of shares owned, but by the dollar value of the shares on the record
date. Share classes have exclusive voting rights with respect to matters
affecting only that class, including with respect to the distribution plan for
that class. 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 period. Actual results could differ from those estimates.

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

32    Pioneer Europe Select Equity Fund | Semiannual Report | 2/28/09


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 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 prices and/or quotations are not readily
   available are valued using fair value methods pursuant to procedures adopted
   by the Board of Trustees ("management appraised"). At February 28, 2009,
   there were no securities that were management appraised.

   The Fund invests primarily in securities of non-U.S. issuers. The principal
   exchanges and markets for such securities have closing times prior to the
   close of the NYSE. However, the value of these securities may be influenced
   by changes in global markets occurring after the closing times of the local
   exchanges and markets up to the time the Fund determines its net asset value.
   Consequently, the Board of Trustees of the Fund has determined that the use
   of daily fair valuations as provided by a pricing service is appropriate for
   the Fund. The Fund may also take into consideration other significant events
   in determining the fair value of these securities. Thus, the Fund's
   securities valuations may differ from prices reported by the various local
   exchanges and markets. Temporary cash investments are valued at cost which
   approximates market value.

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

   Gains and losses on sales of investments are calculated on the identified
   cost method for both financial reporting and federal income tax purposes.

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.

           Pioneer Europe Select Equity Fund | Semiannual Report | 2/28/09    33


   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 may enter 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, 2009, 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. Tax
   years for the prior three fiscal years remain subject to examination by tax
   authorities.

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

   The Fund has elected to defer approximately $34,492,396 of capital losses
   recognized between November 1, 2007 and August 31, 2008 to its fiscal year
   ending August 31, 2009.

   The tax character of current year distributions paid will be determined at
   the end of the current taxable year. The tax character of distributions paid
   during the year ended August 31, 2008 was as follows:

   Distributions paid from:

- --------------------------------------------------------------------------------
                                                                
   Distributable earnings:

- --------------------------------------------------------------------------------
     Total                                                         $(40,072,633)
================================================================================


   For the fiscal year ended August 31, 2008, the Fund has elected to pass
   through foreign tax credits of $628,997.

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

E. Fund Shares

   The Fund records sales and repurchases of its shares as of trade date.
   Pioneer Funds Distributor, Inc. (PFD), the principal underwriter for the Fund
   and a wholly owned indirect subsidiary of UniCredit S.p.A. (UniCredit),
   earned $9,811 in underwriting commissions on the sale of Class A shares
   during the six months ended February 28, 2009.

F. Class Allocations

   Income, common expenses and realized and unrealized gains and losses are
   calculated at the Fund level and allocated daily to each class of shares
   based on their respective percentage of adjusted net assets at the beginning
   of the day. Distribution fees are calculated based on the average daily net
   asset value attributable to Class A, Class B and Class C shares of the Fund,
   respectively (See Note 4). Class Y shares are not subject to a distribution
   plan. Shareowners of each class participate in all expenses and fees paid to
   the transfer agent, Pioneer Investment Management Shareholder Services, Inc.
   (PIMSS), for its services, which are allocated based on the number of
   accounts in each class and the ratable allocation of related out-of-pocket
   expenses (see Note 3).

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

           Pioneer Europe Select Equity Fund | Semiannual Report | 2/28/09    35


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

2. Management Agreement

Pioneer Investment Management, Inc. (PIM), a wholly owned indirect subsidiary
of UniCredit, manages the Fund's portfolio. Management fees are calculated
daily at the annual rate of 0.85% of the Fund's average daily nets assets up to
$500 million; and 0.75% of the excess over $500 million. For the six months
ended February 28, 2009, the net management fee (net of waivers and/or
assumption of expense) was equivalent to 0.84% of the Fund's average daily net
assets.

Effective October 1, 2007, PIM has contractually agreed to limit ordinary
operating expenses to the extent required to reduce Fund expenses to 1.50%,
2.40% and 2.40% of the average daily net assets attributable to Class A, Class
B and Class C shares, respectively. Class Y shares do not have an expense
limitation. These expense limitations are in effect through January 1, 2012 for
Class A shares and through January 1, 2010 for Class B and Class C shares.

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

In addition, under the management and administration agreements, certain other
services and costs, including accounting, regulatory reporting and insurance
premiums, are paid by the Fund. Included in "Due to affiliates" reflected on
the Statement of Assets and Liabilities is $3,834 in management fees,
administrative costs and certain other fees payable to PIM at February 28,
2009.

3. Transfer Agent

PIMSS, a wholly owned indirect subsidiary of UniCredit, provides substantially
all transfer agent and shareowner services to the Fund at negotiated rates.

In addition, the Fund reimbursed PIMSS for out-of-pocket expenses related to
shareholder communications activities such as proxy and statement mailings,
outgoing phone calls and omnibus relationship contracts. For the six months
ended February 28, 2009, such out of pocket expenses by class of shares were as
follows:

  Class A                                                             $ 37,906

================================================================================


36    Pioneer Europe Select Equity Fund | Semiannual Report | 2/28/09


Included in "Due to affiliates" reflected on the Statement of Assets and
Liabilities is $52,309 in transfer agent fees and shareholder communications
expense payable to PIMSS at February 28, 2009.

4. Distribution Plan

The Fund adopted a Distribution Plan pursuant to Rule 12b-1 of the Investment
Company Act of 1940 with respect to Class A, Class B and Class C shares.
Pursuant to the Plan, the Fund pays PFD 0.25% of the average daily net assets
attributable to Class A shares as compensation for personal services and/or
account maintenance services or distribution services with regard to Class A
shares. Pursuant to the Plan, the Fund pays PFD 1.00% of the average daily net
assets attributable to Class B and Class C shares. The fee for Class B and
Class C shares consists of a 0.25% service fee and a 0.75% distribution fee
paid as compensation for personal services and/or account maintenance services
with regard to Class B and Class C shares. Included in "Due to affiliates"
reflected on the Statement of Assets and Liabilities is $1,257 in distribution
fees payable to PFD at February 28, 2009.

In addition, redemptions of each class of shares (except Class Y shares) may be
subject to a contingent deferred sales charge (CDSC). A CDSC of 1.00% may be
imposed on redemptions of certain net asset value purchases of Class A shares
within 18 months of purchase. Class B shares that are redeemed within five
years of purchase are subject to a CDSC at declining rates beginning at 4.00%,
based on the lower of cost or market value of shares being redeemed.
Redemptions of Class C shares within one year of purchase are subject to a CDSC
of 1.00%, based on the lower of cost or market value of shares being redeemed.
There is no CDSC for Class Y shares. Proceeds from the CDSCs are paid to PFD.
For the six months ended February 28, 2009, CDSCs in the amount of $6,494 were
paid to PFD.

5. Expense Offset Arrangements

The Fund has entered into certain expense offset arrangements with PIMSS
resulting in a reduction in the Fund's total expenses due to interest earned on
cash held by PIMSS. For the six months ended February 28, 2009 the Fund's
expenses were reduced by $2,187 under such arrangements.

6. Line of Credit Facility

The Fund, along with certain other funds in the Pioneer Family of Funds (the
Funds), collectively participate in a $165 million committed, unsecured
revolving line of credit facility. Borrowings are used solely for temporary or
emergency purposes. The Fund may borrow up to the lesser of $165 million or the
limits set by its prospectus for borrowings. Interest on collective borrowings
is

           Pioneer Europe Select Equity Fund | Semiannual Report | 2/28/09    37


payable at the Federal Funds Rate plus 1/2% on an annualized basis. The Funds
pay an annual commitment fee for this facility. The commitment fee is allocated
among such Funds based on their respective borrowing limits. For the six months
ended February 28, 2009, the Fund had no borrowings under this agreement.

7. New Pronouncement

In March 2008, Statement of Financial Accounting Standards No. 161, Disclosures
about Derivative Instruments and Hedging Activities (SFAS 161), was issued and
is effective for fiscal years beginning after November 15, 2008. SFAS 161
requires enhanced disclosures about an entity's derivative and hedging
activities. Management is currently evaluating the impact the adoption of SFAS
161 will have on the Fund's financial statement disclosures.

8. Subsequent Event

The reorganization of the Fund into Pioneer Global Equity Fund (formerly,
Pioneer Global Select Equity Fund) has been approved by the Board of Trustees.
Each fund is managed by PIM. The reorganization, which does not require
shareholder approval, is expected to qualify as a tax-free reorganization and
be completed on or about June 12, 2009.

 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.

                 not performed by the Audit
                 firm, the scope of the Audit
                 Services would likely
                 increase.  The Services are
