President's Letter

Dear Shareowner,

Stock and bond markets around the globe this year have experienced 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 1920's. One lesson he learned is
that while great prosperity affords an advantageous time for selling stocks,
extreme business 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 have been unjustifiably beaten down by indiscriminate
selling, but that nonetheless have 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 is supported by an integrated team approach and results in the careful
balance of risk and reward that we apply to each of our portfolios. While we


2    Pioneer Europe Select Equity Fund | Annual Report | 8/31/08


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 | Annual Report | 8/31/08    3


Portfolio Management Discussion | 8/31/08

Widening expectations of a deceleration in growth, both in Europe and globally,
pulled down equity prices throughout Europe over the 12 months ending August
31, 2008. The losses incurred by U.S. investors from investing in European
stocks, however, were partially buffered by the effects of the strengthening
euro against the U.S. dollar. In the following discussion, Andrew Arbuthnott
reviews the factors that affected the performance of Pioneer Europe Select
Equity Fund during the 12 months ending August 31, 2008. 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 12 months ending
   August 31, 2008?

A  Pioneer Europe Select Equity Fund's Class A Shares returned -26.34% at net
   asset value over the period, while its benchmark, the MSCI Europe Index,
   declined 14.03%. The average return of the 108 funds in Lipper's European
   Region Funds category was -17.13% over the same period.

Q  What was the investment environment like during the 12 months?

A  Stocks throughout Europe performed very poorly for the period as economic
   growth on the Continent slowed noticeably and equity analysts steadily
   lowered their estimates of corporate profit growth for 2009 as well as the
   remainder of 2008. The most dominant influence tugging on equity values was
   the growing credit crisis that restricted lending activity. While the
   credit crisis started with the weakening in housing and in mortgages in the
   United States, it spread to affect capital markets throughout the world,
   including in Europe. The Continent's principal currency -- the euro --
   gained 8% in value relative to the U.S. dollar over the 12 months, even
   after retreating somewhat in the final month of the fiscal year. The strong
   euro helped U.S. equity investors absorb some of the losses in stock values
   in Europe. The MSCI Europe Index lost more than 20% in local currencies,
   but about 14% after the effects of currency changes were included. However,
   the strong currency added to the slowing influences on the European economy
   by handicapping the ability of European corporations to compete in global
   markets on the basis of price. Compounding the problems related to this
   decelerating growth, the prices of oil, natural gas and other commodities
   rose significantly, putting pressure on the profits and operating margins
   of many industries and undermining growth in consumer spending. In this
   environment, inflation increased, with the rate of growth of the consumer
   price index (CPI) in Europe doubling from 2% to 4% during the 12-month
   period. As a consequence, the European Central Bank, whose


4    Pioneer Europe Select Equity Fund | Annual Report | 8/31/08


   central charter is to control inflationary pressures, increased short-term
   interest rates, further tightening the supply of available credit.

   Markets such as those in Spain, the United Kingdom, Ireland and some
   Scandinavian countries, which had shown the greatest growth before 2007,
   were among those that endured the greatest relative weakening during the
   period. In contrast, slower-growth markets, such as those in Germany,
   France and Italy, experienced less deceleration in growth.

   In this environment, stock averages in all industry groups generated
   negative returns for the 12 months. The industries that showed the greatest
   relative strength, despite declines in average stock values, were software
   and technology services, utilities, materials, energy, food, beverage and
   tobacco and health care. The industries that tended to produce the poorest
   returns, on a relative basis, were the retail, banking, diversified
   financials, semiconductor, real estate and technology hardware groups. Most
   major financial institutions produced particularly weak results because of
   their exposure to the credit crisis, which forced the government in the
   United Kingdom to take over one home lending company.

Q  What types of investments most influenced the Fund's relative performance
   over the 12 months ending August 31, 2008?

A  The most serious drag on Fund results, contributing to the underperformance
   relative to the MSCI Europe Index, was the overweighting of consumer
   discretionary stocks, especially consumer durables, early in the fiscal
   year. In particular, the Fund's investments in two homebuilding companies
   in the United Kingdom -- Persimmon and Taylor Wimpey -- proved to be major
   detractors from performance before the Fund liquidated the positions in
   both companies. The Fund's investments in two automotive-related companies
   also detracted from performance during the period. Both Daimler, the German
   car company, and Michelin, the French tire company, were hit at the same
   time by slowing demand for their products and rising raw materials prices.
   The Fund sold both positions. Investments in the weak-performing financials
   sector also hurt relative returns. Among the financials stocks that
   underperformed were Royal Bank of Scotland, which was recapitalized during
   the year, and Dexia, a French/Belgian institution whose diversified
   operations include a bond insurer with exposure to the United States. In
   contrast, BNP Paribas, the French institution, performed very well during
   the period as it worked through its internal credit-related problems. Also
   holding back performance was the Fund's position in CRH, the Ireland-based
   global building materials company that was hurt by slowing construction
   activity arising out of the decline in housing activity.

   In a challenging year, several holdings did perform well. Fresenius, the
   German health services company, performed well based on the consistent
   demand for its dialysis products and services for the treatment of kidney


                Pioneer Europe Select Equity Fund | Annual Report | 8/31/08    5


   patients throughout the globe. TNT, the Dutch based transportation services
   companies, appreciated in value. Its operations include the postal service
   in the Netherlands as well as an express package delivery service. Parts of
   TNT's stock gains were related to reports that its delivery service might
   be sought by others in the industry. Also helping results were the Fund's
   underweighted positions in two weak-performing industries: retailing and
   insurance.

Q  What changes were made in the Fund's portfolio during the 12 months?

A  We substantially reduced the Fund's exposure to consumer discretionary
   stocks, especially in durable goods, where we eliminated investments in
   British homebuilders Taylor Wimpey and Persimmon, as well as auto-related
   investments in Daimler, Michelin and Volvo, the Swedish truck manufacturer.
   We also sold the Fund's investment in BSkyB, the British-based pay-for-view
   broadcasting company because of concerns about its vulnerability as
   consumers feel the pressures from a slowing economy and rising price
   pressures. At the same time, the Fund added investments in companies that
   we believed had more stable earnings growth prospects, including defense
   contractors BAE Systems of the United Kingdom and Thales Group of France.
   Other companies that the Fund added included: Technip, the French oil field
   services company; Reed Elsevier of the Netherlands, a publisher of
   materials for professional audiences, including ones in the scientific and
   medical fields; and Bayer, the German pharmaceutical corporation that we
   believed had a strong pipeline of potential new products in development.

Q  What is your investment outlook?

A  While challenges remain in Europe, we think some potentially interesting
   values exist in equity markets, as evidenced by continued merger-and-
   acquisition and private equity activities. Any combination of several
   potential catalysts could lead investors to recognize the existing values
   in European stocks. These catalysts could include: easing of inflationary
   pressures; a stabilization of the housing market in the United States; or
   an upswing in merger-and-acquisition activity.

   If inflationary pressures in Europe begin to recede, the European Central
   Bank may become more accommodative to growth by lowering short-term
   interest rates. If that were to occur, we think investors may begin to be
   attracted to the interesting values we already are seeing in many European
   stocks, which continue to offer relatively high stock dividend yields.

   One encouraging sign has been the move by several major European
   institutions to take advantage of the strength of the euro to make
   acquisition offers to American corporations. Inbev's proposal to take over
   Anheuser-Busch and Roche's plan to acquire the remaining shares of
   Genentech are two


6    Pioneer Europe Select Equity Fund | Annual Report | 8/31/08


   good examples. Moreover, we think there may be further consolidation in the
   banking industry, as we have already seen with the planned merger of
   Commerzbank and Dresdner Bank in Germany.

   We plan to maintain a relatively concentrated portfolio of companies,
   typically between 30 and 35 different companies. We think we should be able
   to find some good opportunities in Europe, especially when investors begin
   to recognize the values that we think already exist.


















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.

Comparing Ongoing Fund Expenses

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

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

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

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


Using the Tables
- --------------------------------------------------------------------------------
Actual Expenses

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

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

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

Hypothetical Example for Comparison Purposes

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


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

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

Notes to Financial Statements | 8/31/08

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 have equal rights to voting, redemptions, dividends
and liquidation, except that each class of shares can bear different transfer
agent and distribution fees and have exclusive voting rights with respect to
the distribution plans that have been adopted by Class A, Class B and Class C
shareowners, respectively. There is no distribution plan for Class Y shares.

The Fund's financial statements have been prepared in conformity with U.S.
generally accepted accounting principles that require the management of the
Fund to, among other things, make estimates and assumptions that affect the
reported amounts of assets and liabilities, the disclosure of contingent assets
and liabilities at the date of the financial statements, and the reported
amounts of revenues and expenses during the reporting period. Actual results
could differ from those estimates.

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

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


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


32    Pioneer Europe Select Equity Fund | Annual Report | 8/31/08


   date of valuation, or securities for which sale prices are not generally
   reported, are valued at the mean between the last bid and asked prices.
   Securities for which market quotations are not readily available are valued
   at their fair values as determined by, or under the direction of, the Board
   of Trustees. The Fund invests primarily in securities of non-U.S. issuers.
   The principal exchanges and markets for such securities have closing times
   prior to the close of the NYSE. However, the value of these securities may be
   influenced by changes in global markets occurring after the closing times of
   the local exchanges and markets up to the time the Fund determines its net
   asset value. Consequently, the Board of Trustees of the Fund has determined
   that the use of daily fair valuations as provided by a pricing service is
   appropriate for the Fund. The Fund may also take into consideration other
   significant events in determining the fair value of these securities. Thus,
   the Fund's securities valuations may differ from prices reported by the
   various local exchanges and markets. At August 31, 2008, there were no fair
   valued securities. 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.

   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.


               Pioneer Europe Select Equity Fund | Annual Report | 8/31/08    33


C. Forward Foreign Currency Contracts

   The Fund enters into forward foreign currency contracts (contracts) for the
   purchase or sale of a specific foreign currency at a fixed price on a future
   date as a hedge or cross-hedge against either specific investment
   transactions (settlement hedges) or portfolio positions (portfolio hedges).
   All contracts are marked to market daily at the applicable exchange rates and
   any resulting unrealized gains or losses are recorded in the Fund's financial
   statements. The Fund records realized gains and losses at the time a
   portfolio hedge is offset by entering into a closing transaction or
   extinguished by delivery of the currency. Risks may arise upon entering into
   these contracts from the potential inability of counterparties to meet the
   terms of the contract and from unanticipated movements in the value of
   foreign currencies relative to the U.S. dollar. At August 31, 2008, 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 prior to 2004 are closed (not subject to examination by tax
   authorities) due to the expiration of the statute of limitations; all other
   tax years are open.

   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.

   At August 31, 2008, the Fund has reclassified $39,833 to increase
   undistributed net investment income and $39,833 to increase accumulated net
   realized loss on investments and foreign currency transactions to reflect
   permanent book/tax differences. The reclassification has no impact on the net
   asset value of the Fund and is designed to present the Fund's capital
   accounts on a tax basis.

   The 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.


34    Pioneer Europe Select Equity Fund | Annual Report | 8/31/08


   The tax character of distributions paid during the years ended August 31,
   2008 and August 31, 2007 was as follows:




                                                   2008                 2007

   Distributions paid from:
   Ordinary income                              $ 4,246,446          $ 2,328,114
   Long-term capital gain                        43,718,641                 --
   -----------------------------------------------------------------------------
    Total                                       $47,965,087          $ 2,328,114
   =============================================================================


  The following shows the components of distributable earnings on a federal
  income tax basis at August 31, 2008:




                                                                       2008
                                                               
   -----------------------------------------------------------------------------
   Distributable earnings:
   Undistributed ordinary income                                  $   3,204,953
   Post-October loss deferred                                       (34,492,396)
   Unrealized depreciation                                           (8,785,190)
   -----------------------------------------------------------------------------
    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 $13,393 in underwriting commissions on the sale of Class A shares
   during the year ended August 31, 2008.


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).


               Pioneer Europe Select Equity Fund | Annual Report | 8/31/08    35


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


2. Management Agreement

Pioneer Investment Management, Inc. (PIM), a wholly owned indirect subsidiary
of 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 year ended
August 31, 2008, the effective management fee (net of waivers and/or assumption
of expense) was equivalent to 0.78% of the Fund's average 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, 2011 for
Class A shares and through January 1, 2009 for Class B and Class C shares.

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

In addition, under the management agreement, management fees, administrative
costs and fees for certain other services, including accounting, regulatory
reporting and insurance, are paid by the Fund. Included in "Due to affiliates"
reflected on the Statement of Assets and Liabilities is $13,822 in management
fees, administrative costs and certain other services payable to PIM at August
31, 2008.


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.
Included in "Due to affiliates" reflected on the Statement of Assets and
Liabilities is $57,831 in transfer agent fees payable to PIMSS at August 31,
2008.


4. Distribution Plans

The Fund adopted a Plan of Distribution with respect to Class A, Class B and
Class C shares in accordance with Rule 12b-1 of the Investment Company Act of
1940. 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


36    Pioneer Europe Select Equity Fund | Annual Report | 8/31/08


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 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. Prior to February 1, 2008, PFD was
reimbursed under the Plan of Distribution for distribution expenses in an
amount of up to 0.25% of the average daily net assets attributable to Class A
shares. Included in "Due to affiliates" reflected on the Statement of Assets
and Liabilities is $3,825 in distribution fees payable to PFD at August 31,
2008.

In addition, redemptions of each class of shares (except Class Y shares) may be
subject to a contingent deferred sales charge (CDSC). A CDSC of 1.00% may be
imposed on redemptions of certain net asset value purchases of Class A shares
within 18 months of purchase. Class B shares that are redeemed within five
years of purchase are subject to a CDSC at declining rates beginning at 4.00%,
based on the lower of cost or market value of shares being redeemed.
Redemptions of Class C shares within one year of purchase are subject to a CDSC
of 1.00%, based on the lower of cost or market value of shares being redeemed.
Proceeds from the CDSCs are paid to PFD. For the year ended August 31, 2008,
CDSCs in the amount of $44,957 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 year ended August 31, 2008 the Fund's expenses were
reduced by $18,776 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 $200 million committed, unsecured
revolving line of credit facility. Borrowings are used solely for temporary or
emergency purposes. The Fund may borrow up to the lesser of $200 million or the
limits set by its prospectus for borrowings. Interest on collective borrowings
is payable at the Federal Funds Rate plus 1/2% on an annualized basis. The
Funds pay an annual commitment fee for this facility. The commitment fee is
allocated among such Funds based on their respective borrowing limits. For the
year ended August 31, 2008, the Fund had no borrowings under this agreement.


7. New Pronouncements

In September 2006, Statement of Financial Accounting Standards No. 157, Fair
Value Measurements (SFAS 157), was issued and is effective for fiscal years
beginning after November 15, 2007. SFAS 157 defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair value


               Pioneer Europe Select Equity Fund | Annual Report | 8/31/08    37


measurements. Management is currently evaluating the impact the adoption of
SFAS 157 will have on the Fund's financial statement disclosures.

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.

indicated therein. These financial statements and financial highlights are the
responsibility of the Fund's management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we
plan and perform the audit to obtain reasonable assurance about whether the
financial statements and financial highlights are free of material
misstatement. We were not engaged to perform an audit of the Fund's internal
control over financial reporting. Our audits included consideration of internal
control over financial reporting as a basis for designing audit procedures that
are appropriate in the circumstances, but not for the purpose of expressing an
opinion on the effectiveness of the Fund's internal control over financial
reporting. Accordingly, we express no such opinion. An audit also includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements and financial highlights, assessing the accounting
principles used and significant estimates made by management, and evaluating
the overall financial statement presentation. Our procedures included
confirmation of securities owned as of August 31, 2008, by correspondence with
the custodian and brokers or by other appropriate auditing procedures where
replies from brokers were not received. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
Pioneer Europe Select Equity Fund at August 31, 2008, the results of its
operations for the year then ended, the changes in its net assets for each of
the two years in the period then ended, and the financial highlights for each
of the periods indicated therein, in conformity with U.S. generally accepted
accounting principles.

Approval of Investment Advisory Agreement

Pioneer Investment Management, Inc. (PIM) serves as the Fund's investment
adviser pursuant to an investment advisory agreement between PIM and the Fund.
The Trustees of the Fund, as required by law, determine annually whether to
continue the investment advisory agreement for the Fund. In connection with
their most recent consideration of the investment advisory agreement for the
Fund, the Trustees received and reviewed a substantial amount of information
provided by PIM in response to requests of the independent Trustees and their
independent legal counsel. The independent Trustees met on a number of
occasions with PIM and also separately with their independent legal counsel to
evaluate and discuss the information provided to them by PIM. At a meeting held
on November 13, 2007, based on their evaluation of the information provided by
PIM, the Trustees, including the independent Trustees voting separately,
unanimously approved the continuation of the investment advisory agreement for
another year.

At a meeting held on January 8, 2008, the Trustees considered whether an
amended and restated investment advisory agreement for the Fund should be
approved for an initial period ending December 31, 2009. The management fee to
be paid by the Fund to PIM under the amended and restated investment advisory
agreement is the same as the management fee provided in the previously approved
investment advisory agreement. Based on their evaluation of the information
provided by PIM, including the information provided by PIM in connection with
the Trustees' most recent approval of the continuation of the previous
investment advisory agreement, the Trustees, including the independent Trustees
voting separately, unanimously approved the amended and restated investment
advisory agreement. Shareholders of the Fund approved the amended and restated
investment advisory agreement at a meeting held on May 13, 2008.

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

Nature, Extent and Quality of Services

The Trustees considered the nature, extent and quality of the services that
were provided by PIM to the Fund under the previous investment advisory
agreement, and that would continue to be provided by PIM to the Fund under the
amended and restated investment advisory agreement, taking into account the
investment objective and strategy of the Fund and the information related to


               Pioneer Europe Select Equity Fund | Annual Report | 8/31/08    43


the Fund provided to the Trustees at each quarterly meeting. The Trustees
reviewed the terms of the amended and restated investment advisory agreement.
The Trustees also reviewed PIM's investment approach for the Fund and its
research process. The Trustees considered the resources of PIM and the
personnel of PIM who provide investment management services to the Fund. They
also considered PIM's compliance and legal resources and personnel.

In addition, the Trustees considered the other services that PIM provided under
the previous investment advisory agreement and that PIM would continue to
provide to the Fund under the amended and restated investment advisory
agreement and that, as administrator, PIM is responsible for the administration
of the Fund's business and other affairs. It was noted that PIM supervises and
monitors the performance of the Fund's service providers and provides the Fund
with personnel (including officers) as are necessary for the Fund's operations.
The Trustees considered the fees paid to PIM for the provision of such
services.

Based on these considerations, the Trustees concluded that the nature, extent
and quality of services that PIM would continue to provide to the Fund under
the amended and restated investment advisory agreement, were satisfactory and
consistent with the terms of the amended and restated investment advisory
agreement.


Performance of the Fund

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


Management Fee and Expenses

The Trustees considered that the management fee to be paid by the Fund to PIM
under the amended and restated investment advisory agreement would be the same
as the management fee to be paid by the Fund under the previously approved
investment advisory agreement. The Trustees considered information on the fees
and expenses of the Fund in comparison to the management fees of its peer group
of funds as classified by Morningstar and the expense


44    Pioneer Europe Select Equity Fund | Annual Report | 8/31/08


ratios of a peer group of funds selected on the basis of criteria determined by
the independent Trustees for this purpose using data provided by Strategic
Insight Mutual Fund Research and Consulting, LLC (Strategic Insight), an
independent third party.

The Trustees considered that the Fund's management fee for the twelve months
ended June 30, 2007 was in the third quintile relative to the management fees
paid by other funds in its peer group Morningstar category for the comparable
period. The Trustees also considered that the Fund's expense ratio for the
twelve months ended June 30, 2007 was in the fifth quintile relative to its
Strategic Insight peer group. The Trustees noted PIM's agreement to lower the
contractual expense limitation for the Fund and that the lowered expense cap
was in line with the median expense ratio of the Fund's Strategic Insight peer
group for the twelve months ended June 30, 2007. It was noted that PIM did not
currently manage any accounts with an investment objective and strategies that
were similar to the Fund.

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


Profitability

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

Economies of Scale

The Trustees considered the economies of scale with respect to the management
of the Fund, whether the Fund had appropriately benefited from any economies of
scale, and whether there was potential for realization of any further economies
of scale. The Trustees concluded that, because of the breakpoints in the
management fee schedule and the reduced fee rates above certain asset levels,
any perceived or potential economies of scale would be shared between PIM and
the Fund.


Other Benefits

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


Conclusion

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

 PIONEER FUNDS
            APPROVAL OF AUDIT, AUDIT-RELATED, TAX AND OTHER SERVICES
                       PROVIDED BY THE INDEPENDENT AUDITOR

                  SECTION I - POLICY PURPOSE AND APPLICABILITY

The Pioneer Funds recognize the importance of maintaining the independence of
their outside auditors. Maintaining independence is a shared responsibility
involving Pioneer Investment Management, Inc ("PIM"), the audit committee and
the independent auditors.

The Funds recognize that a Fund's independent auditors: 1) possess knowledge of
the Funds, 2) are able to incorporate certain services into the scope of the
audit, thereby avoiding redundant work, cost and disruption of Fund personnel
and processes, and 3) have expertise that has value to the Funds. As a result,
there are situations where it is desirable to use the Fund's independent
auditors for services in addition to the annual audit and where the potential
for conflicts of interests are minimal. Consequently, this policy, which is
intended to comply with Rule 210.2-01(C)(7), sets forth guidelines and
procedures to be followed by the Funds when retaining the independent audit firm
to perform audit, audit-related tax and other services under those
circumstances, while also maintaining independence.

Approval of a service in accordance with this policy for a Fund shall also
constitute approval for any other Fund whose pre-approval is required pursuant
to Rule 210.2-01(c)(7)(ii).

In addition to the procedures set forth in this policy, any non-audit services
that may be provided consistently with Rule 210.2-01 may be approved by the
Audit Committee itself and any pre-approval that may be waived in accordance
with Rule 210.2-01(c)(7)(i)(C) is hereby waived.

Selection of a Fund's independent auditors and their compensation shall be
determined by the Audit Committee and shall not be subject to this policy.

                 firm, the scope of the Audit

                 increase.  The Services are

- --------------------------------------------------------------------------------
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.

Beginning with non-audit service contracts entered into on or
after May 6, 2003, the effective date of the new SEC pre-approval
rules, the Fund's audit committee is required to pre-approve
services to affiliates defined by SEC rules to the extent that
the services are determined to have a direct impact on the
operations or financial reporting of the Fund.  For the years
ended August 31, 2007 and 2006, there were no services provided
to an affiliate that required the Fund's audit committee pre-approval.

(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 aggregate non-audit fees for the Fund and affiliates, as
previously defined, totaled approximately $8,290 in 2008 and
$7,820 in 2007.


(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.

considered whether the provision of non-audit services that
were rendered to the Affiliates (as defined) 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.

paragraph (b) of this Item with respect to any purchase made by or on
behalf of the registrant or any affiliated purchaser, as defined in

(a) Disclose the conclusions of the registrant's principal executive officer or
officers and principal financial officer or officers, or persons performing
similar functions, about the effectiveness of the registrant's disclosure
controls and procedures (as defined in Rule 30a-2(c) under the Act (17 CFR
270.30a-2(c))) based on their evaluation of these controls and procedures as of
a date within 90 days of the filing date of the report that includes the
disclosure required by this paragraph.

The registrant's principal executive officer
