President's Letter


Dear Shareowner,

During the first three quarters of 2011, the U.S. economy struggled to gain
solid footing. The economy went through a soft patch in the first half, and the
second half, so far, has been highlighted by the U.S. government's battle over
the debt ceiling and Standard & Poor's downgrade of the U.S. Treasury's credit
rating from the top rating of "AAA" for the first time in history. After
rallying nicely in the first half, U.S. equity markets reacted sharply this
summer to the political stalemate and the downgrade. There has been continued
pressure on equities due to concerns about the growing European sovereign-debt
crisis and its potential impact on the global economy.

Despite legitimate reasons for concern, we believe there are also reasons for
optimism that the U.S. economy will continue to exhibit modest growth and is
not headed into a severe recession. Corporations continue to post solid
earnings and, for the most part, are maintaining their positive earnings
outlooks. They also have strong balance sheets with improved net leverage and
high cash levels. Auto production has rebounded following the Japanese
supply-chain interruptions caused by the earthquake and tsunami last spring.
Retail sales growth year-over-year has remained steady despite low consumer
confidence. And despite high unemployment in the U.S., private sector
employment has grown consistently, albeit modestly, since February 2010. There
are certainly risks to our outlook, including possible contagion from the
European sovereign-debt and banking crisis, the fiscal drag from federal and
state budget cuts in the U.S., as well as potential "negative feedback loops"
from capital-market volatility. But broadly speaking, we think the subpar
economic recovery is consistent with recoveries from other "balance
sheet"-caused recessions.

The difficult recovery process has been accompanied by wide market swings.
While this is a challenging environment, our investment professionals continue
to focus on finding good investment opportunities in both equity and bond
markets, using the same disciplined approach Pioneer has used since 1928. Our
approach is to identify undervalued individual securities with the greatest
potential for success, carefully weighing risk against reward. Our teams of
investment professionals continually monitor and analyze the relative
valuations of different sectors and securities globally to help build
portfolios that we believe can help you achieve your investment goals.

Portfolio Management Discussion | 11/30/11

Equity markets experienced sharp swings during Pioneer International Value
Fund's fiscal year ended November 30, 2011, in response to global economic
concerns. In the following interview, Marco Pirondini, head of equities, U.S.,
and portfolio manager for Pioneer in Boston, and Andrea Salvatori, senior vice
president, portfolio manager, and a member of Pioneer's international
investment team in Dublin, Ireland, discuss the factors that influenced the
Fund's performance over the 12-month period, and their investment strategy for
managing the portfolio amid the market volatility.

Q How did the Fund perform during the 12 months ended November 30, 2011?

A Pioneer International Value Fund Class A shares returned -2.84% at net asset
  value during the 12 months ended November 30, 2011, while the Fund's
  benchmark, the Morgan Stanley Capital International (MSCI) Europe,
  Australasia, Far East (EAFE) Index1 (the MSCI Index), returned -3.68%. During
  the same 12-month period, the average return of the 212 mutual funds in
  Lipper's International Multi-Cap Core Funds category was -5.02%. Thanks in
  large part to defensive positioning, which curtailed the portfolio's exposure
  to European financials stocks, the Fund outperformed its MSCI Index benchmark
  and Lipper peer funds category average. The bulk of the outperformance was
  achieved during the July to September 2011 period, when international markets
  fell sharply.

Q How would you characterize the investment environment for international stocks
  during the 12 months ended November 30, 2011?

A The 12-month reporting period was a tale of two halves, with the first six
  months of the period characterized by a tepid economic recovery and some
  easing of financial stresses, enabling international markets to post
  double-digit returns. However, by the summer months, renewed fears about
  Europe's sovereign-debt woes and the future of the euro currency, the U.S.
  budget debate, and slowing economic growth in China raised questions about the
  state of the global recovery. With signs of economic activity moderating in
  the major industrial economies, investors became more cautious and sold
  higher-risk assets. The sell-off pushed international stock markets lower
  during the second half of the reporting period, despite a relief rally in the
  month of October when euro fears temporarily eased.

Q Are you optimistic about the future of the euro and the European Monetary
  Union (EMU)?

A We believe that the euro will survive the crisis, as the Europeans appear to
  be working on a solution that could eventually bring about a better and


4    Pioneer International Value Fund | Annual Report | 11/30/11
<PAGE>

  more sustainable framework. Just following the close of the reporting period,
  after November 30, 2011, all 17 nations of the EMU agreed to sign a treaty
  that grants a central authority closer oversight of their budgets. However, we
  believe the long-term adjustments and costs associated with having a closer
  fiscal union in order to save the single currency will be painful for the
  member nations.

  We believe that deleveraging and austerity measures will bring Europe closer
  to resembling the Japanese malaise of the past decade, and will be
  characterized by tight liquidity, minimal growth, and deflation. However, we
  trust that the European Central Bank (ECB) will actively moderate the process
  and take the necessary steps to promote stability by infusing liquidity into
  the financial markets, thus avoiding the more pessimistic scenarios. We would
  not be surprised to see the ECB move in the same direction as the Federal
  Reserve Board (the Fed) and lower short-term interest rates to near-zero
  levels. As if to underscore our line of thinking, the ECB reduced interest
  rates for a second straight month in December 2011, shortly after the Fund's
  fiscal year ended, in order to stimulate bank lending and fight off a
  recession.

Q Did you make any significant changes to your investment strategy for the Fund
  during the 12-month period ended November 30, 2011?

A Throughout the Fund's fiscal year, we maintained a defensive bias in the
  Fund's portfolio in order to minimize price volatility. The positioning was
  defined by a below-benchmark weighting in European banks and commodity-related
  stocks. During the second half of the reporting period, from June 1, 2011,
  through November 30, 2011, with international markets declining, we found
  valuations to be compelling, particularly in the financials and consumer
  discretionary sectors. That said, we still adhered to a strategy that has been
  consistently rewarding during these turbulent times, one which seeks companies
  with strong balance sheets. We also have been paying more attention to the
  dividend-yield attributes of international stocks, as income from dividends
  can help provide a buffer in volatile markets. Needless to say, stock-picking
  has been very difficult in the volatile market environment that we've seen
  over the past several months, a volatility driven more by macroeconomic
  factors than corporate fundamentals in our view. The volatility trends have
  resulted in several swings in investors' attitude regarding risk, which have
  often dragged down both individual stocks and entire sectors indiscriminately.

Q Did you change the Fund's geographic distribution materially in response to
  the challenges facing the EMU during the 12 months ended November 30, 2011?


A The recent economic and financial challenges across Europe have contributed to
  a broad-based economic slowdown in the region. As occurred


               Pioneer International Value Fund | Annual Report | 11/30/11     5
<PAGE>

  during the financial crisis of 2008, when the majority of the established
  industrialized countries slid into recession, the dynamic growth of and demand
  emanating from the emerging economies has been helping to lead the global
  economy today. In contrast, the established economies of Europe and the United
  States have been struggling against unfavorable demographic trends and
  excessive debt. As a result, there has been an ever-increasing outflow of
  investor capital from the developed markets into the new and attractive
  markets in Asia, southeastern Europe and Latin America.

  We have increased the Fund's exposure to Latin America at the expense of Asia
  -- particularly in the Brazilian banking sector, where we found especially
  compelling opportunities. But we also are mindful of the fact that, in the
  absence of solvency issues, current valuations in the European equity markets
  do represent interesting buying opportunities for the medium term, on a
  case-by-case basis. Thus, we did not materially change the Fund's allocation
  to Europe during the 12 months ended November 30, 2011.

Q Which holdings or sector allocation decisions contributed to the Fund's
  performance during the 12-month period ended November 30, 2011?

A From a sector perspective, the strongest contributors to the Fund's
  performance during the period came from health care, information technology,
  utilities, and materials.

  One of the Fund's best individual performers during the period was Spanish oil
  and gas company Repsol, which benefited from the surge in oil prices in the
  early part of the Fund's fiscal year. In addition, Synthes, a leading global
  medical device company that specializes in orthopedic devices, rallied
  significantly following the company's announcement in April 2011 that it was
  being purchased by Johnson & Johnson.

  GlaxoSmithKline also performed well for the Fund in a year where earnings
  visibility and cash returns from dividends and share buy-back programs were
  prized by investors. Furthermore, with the introduction of some key drugs, the
  pharmaceutical giant proved that it has the pipeline to fuel earnings over the
  longer term.

  In the consumer staples sector, FamilyMart is another defensive holding in the
  portfolio that offers a stable earnings profile, which is something investors
  avidly sought during the period. Lastly, after patiently waiting for a
  turnaround that materialized in 2011, we sold the Fund's position in
  used-packaging recycler Tomra Systems, in order to lock in profits from the
  considerable appreciation of the company's stock price.


6    Pioneer International Value Fund | Annual Report | 11/30/11
<PAGE>

Q Which sector allocations or holdings detracted from the Fund's results during
  the 12 months ended November 30, 2011?

A The financials and consumer discretionary sectors proved to be the biggest
  laggards during the 12-month period. The performance of financials stocks was
  highly correlated to the sovereign-debt crisis in Europe, while the cyclical
  consumer discretionary sector tends to lag in periods of slower growth when
  consumers are less willing to spend.

  As concerns about the debt crisis in Europe and the United States grew, banks
  and other financial institutions struggled. Our decision to limit the Fund's
  exposure to the sector helped performance on an absolute and
  benchmark-relative basis. However, holding any exposure to the sector proved
  to be a drag on performance during the 12-month period. Fund holdings that
  fell into that category included Societe Generale, Commerzbank, and Credit
  Suisse.

  A Fund holding in Gafisa, a Brazilian residential construction and real estate
  company, underperformed on the news that it had acquired Tendra, an
  acquisition that weighed on Gafisa's operations and balance sheet during the
  period. In a market that was completely averse to leveraged or problematic
  turnarounds, investors looked unfavorably on the acquisition of Tendra, and
  Gafisa's stock sold off in response.

Q What is your outlook for international equity markets?

A Market volatility defined the 12-month reporting period ended November 30,
  2011, and we don't expect much to change in 2012. The global economic recovery
  has been slowing, and much uncertainty exists. We believe it likely that we
  will revisit market lows before policy actions are forced upon politicians and
  central bankers. Once policy makers implement more sound fiscal and monetary
  policy initiatives, however, we think that financial markets will react
  positively. Stock price valuations, especially in emerging markets, remain
  attractive. That said, until the macroeconomic risks subside, we plan to
  maintain our cautious mindset as well as the Fund's more defensive bias.

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.

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 or sectors.

These risks may increase share price volatility.

The MSCI EAFE Index is a commonly used measure of international stocks. Index
returns are calculated monthly, assume reinvestment of dividends and, unlike
Fund returns, do not reflect any fees, expenses or sales charges. It is not
possible to invest directly in an index.

The index defined here pertains to the "Value of $10,000 Investment" and "Value
of $5 Million Investment" charts on pages 11-14.

Call 1-800-225-6292 or visit us.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.

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 April 1, 2013 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 performance data quoted represents past performance, which is no guarantee

"If Held" results represent the percent change in net asset value per share.
Returns would have been lower had sales charges been reflected. "If Redeemed"
returns reflect the deduction of applicable contingent deferred sales charge
(CDSC). 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 is
4% and declines over five years. For more complete information, please see the
prospectus. Note: Shares purchased prior to December 1, 2004 remain subject to
the CDSC in effect at the time you purchased those shares. For performance
information for shares purchased prior to December 1, 2004, please visit

The performance data quoted represents past performance, which is no guarantee

Class C shares held for less than one year are also subject to a 1% contingent
deferred sales charge (CDSC). The performance of Class C shares does not
reflect the 1% front-end sales charge in effect prior to February 1, 2004. If
you paid a 1% sales charge, your returns would be lower than those shown above.
"If Held" results represent the percent change in net asset value per share.

Call 1-800-225-6292 or visit us.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 were first publicly offered on April 16, 2009. Performance shown
for periods prior to the inception of Class Y shares reflects the NAV
performance of the Fund's Class A shares. The performance does not reflect
differences in expenses, including the Rule 12b-1 fees applicable to Class A
shares. Since fees for Class A shares are generally higher than those of Class
Y shares, the performance for Class Y shares prior to their inception would
have been higher than the performance shown. 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.

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.

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.

  respectively, multiplied by the average account value over the period,
  multiplied by 183/365 (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), or redemption fees 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.

  Level 2 -- other significant observable inputs (including quoted prices for
             similar securities, interest rates, prepayment speeds, credit risk,
             etc.)
  Level 3 -- significant unobservable inputs (including the Fund's own
             assumptions in determining fair value of investments)

Generally, equity securities are categorized as Level 1, fixed income
securities and senior loans as Level 2 and securities valued using fair value
methods (other than prices supplied by independent pricing services) as Level
3. See Notes to Financial Statements -- Note 1A.

Notes to Financial Statements | 11/30/11


1. Organization and Significant Accounting Policies

Pioneer International Value Fund (the Fund) is the sole portfolio comprising
Pioneer Series Trust VIII, a Delaware statutory trust. The Fund is 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 designated as Class A, Class B, Class C
and Class Y shares. Class R shares were first publicly offered on April 1, 2003
and ceased operations on February 1, 2007. Class Y shares were first publicly
offered on April 16, 2009. Effective as of the close of business on December
31, 2009, Class B shares are no longer offered to new or existing shareholders,
except that dividends and/or capital gain distributions may continue to be
reinvested in Class B shares, and shareholders may exchange their Class B
shares for Class B shares of other Pioneer funds, as permitted by existing
exchange privileges. 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 rates of 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 from net investment income earned 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. Each share class has
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. Class B shares convert to Class A shares
approximately eight years after the date of purchase.

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 gain or loss on investments during the
reporting period. Actual results could differ from those estimates.


32    Pioneer International Value Fund | Annual Report | 11/30/11
<PAGE>

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 that have traded on an exchange are valued
   using the last sale price on the principal exchange where they are traded.
   Securities that have not traded on the date of valuation, or securities for
   which sale prices are not available, generally are valued using the mean
   between the last bid and asked prices. Short-term fixed income securities
   with remaining maturities of sixty days or less generally are valued at
   amortized cost. Money market mutual funds are valued at net asset value.

   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 daily
   adjustments to the valuation of securities of non-U.S. issuers by utilizing
   an independent pricing service that supplies an appropriate fair value factor
   is appropriate for the Fund.

   Securities for which market prices and/or quotations are not readily
   available or are considered to be unreliable are valued using fair value
   methods pursuant to procedures adopted by the Board of Trustees. The Fund may
   use fair value methods if it is determined that a significant event has
   occurred after the close of the exchange or market on which the security
   trades and prior to the determination of the Fund's net asset value. Examples
   of a significant event might include political or economic news, corporate
   restructurings, natural disasters, terrorist activity or trading halts. Thus,
   the valuation of the Fund's securities may differ from exchange prices.

   At November 30, 2011, one security was valued using fair value methods (in
   addition to securities valued using prices supplied by independent pricing
   services) representing 0.38% of net assets. Inputs used when applying fair
   value methods to value a security may include credit ratings, the financial
   condition of the company, current market conditions and comparable
   securities.

   Dividend income is recorded on the ex-dividend date, except that certain
   dividends from foreign securities where the ex-dividend date may have passed
   are recorded as soon as the Fund becomes aware of the ex-dividend


              Pioneer International Value Fund | Annual Report | 11/30/11     33
<PAGE>

   data in the exercise of reasonable diligence. Interest income, including
   interest on income-bearing cash accounts, is recorded on the accrual basis.
   Dividend and interest income are reported net of unrecoverable foreign taxes
   withheld at the applicable country rates.

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


B. Foreign Currency Translation

   The books and records of the Fund are maintained in U.S. dollars. Amounts
   denominated in foreign currencies are translated into U.S. dollars using
   current exchange rates.

   Net realized gains and losses on foreign currency transactions, 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. All contracts are marked to market daily at the applicable
   exchange rates, and any resulting unrealized gains or losses are recorded in
   the Fund's financial statements. The Fund records realized gains and losses
   at the time a portfolio hedge is offset by entry into a closing transaction
   or extinguished by delivery of the currency. Risks may arise upon entering
   into these contracts from the potential inability of counterparties to meet
   the terms of the contract and from unanticipated movements in the value of
   foreign currencies relative to the U.S. dollar (see Note 6).


D. Federal Income Taxes

   It is the Fund's policy to comply with the requirements of the Internal
   Revenue Code applicable to regulated investment companies and to distribute
   all of its taxable income and net realized capital gains, if any, to its
   share-owners. Therefore, no federal income tax provision is required. Tax
   years for the prior three fiscal years remain subject to examination by
   federal and state tax authorities.

   In addition to the requirements of the Internal Revenue Code, the Fund may
   also be required to pay local taxes on the recognition of capital gains
   and/or


34    Pioneer International Value Fund | Annual Report | 11/30/11
<PAGE>

   the repatriation of foreign currencies in certain countries. During the year
   ended November 30, 2011, the Fund paid no such taxes.

   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 November 30, 2011, the Fund had a net capital loss carryforward of
   $153,460,706, of which the following amounts will expire in 2016 and 2017 if
   not utilized: $30,336,810 in 2016 and $123,123,896 in 2017.

   The Fund has elected to defer approximately $3,493,787 of capital losses
   recognized between November 1, 2011 and November 30, 2011 to its fiscal year
   ending November 30, 2012.

   At November 30, 2011, the Fund reclassified $1,917,961 to decrease
   undistributed net investment income, $8,095,069 to decrease accumulated net
   realized loss and $6,177,108 to decrease paid-in capital, to reflect
   permanent book/tax differences. The reclassification has no impact on the net
   assets of the Fund and presents the Fund's capital accounts on a tax basis.

   Under the recently enacted Regulated Investment Company Modernization Act of
   2010, the Fund will be permitted to carry forward capital losses incurred in
   taxable years beginning after December 22, 2010 for an unlimited period.
   However, any losses incurred during those future years will be required to be
   utilized prior to the losses incurred in pre-enactment tax years. As a result
   of this ordering rule, pre-enactment capital loss carryforwards may be more
   likely to expire unused. Additionally, post-enactment capital losses that are
   carried forward will retain their character as either short-term or long-term
   capital losses rather than being considered all short-term as under previous
   law.

   The tax character of distributions paid during the years ended November 30,
   2011 and November 30, 2010 was as follows:

================================================================================
</TABLE>


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


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 $15,903 in underwriting commissions on the sale of Class A shares
   during the year ended November 30, 2011.


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 its 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 do not pay distribution fees. All expenses and
   fees paid to the transfer agent, Pioneer Investment Management Shareholder
   Services, Inc. (PIMSS), for its services are allocated among the classes of
   shares 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 net investment
   income dividends to Class A, Class B, Class C and Class Y shares can reflect
   different transfer agent and distribution expense rates.


G. Risks

   Investing in foreign and/or emerging markets securities involves risks
   relating to interest rates, currency exchange rates and 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


36    Pioneer International Value Fund | Annual Report | 11/30/11
<PAGE>

   adverse economic, political or regulatory developments affecting those
   countries. At times, the Fund's investments may represent industries or
   industry sectors that are interrelated or have common risks, making the Fund
   more susceptible to any economic, political, or regulatory developments or
   other risks affecting those industries and sectors. The Fund's prospectus
   contains unaudited information regarding the Fund's principal risks. Please
   refer to that document when considering the Fund's principal risks.


H. Securities Lending

   The Fund lends securities in its portfolio to certain broker-dealers or other
   institutional investors. When entering into a securities loan transaction,
   the Fund typically receives cash collateral from the borrower equal to at
   least the value of the securities loaned, which is invested in temporary
   investments. Credit Suisse AG, New York Branch, as the Fund's securities
   lending agent, manages the Fund's securities lending collateral. The income
   earned on the investment of collateral is shared with the borrower and the
   lending agent in payment of any rebate due to the borrower with respect to
   the securities loan, and in compensation for the lending agent's services to
   the Fund. The Fund also continues to receive payments in lieu of dividends or
   interest on the securities loaned. Gain or loss on the value of the loaned
   securities that may occur during the term of the loan will be for the account
   of the Fund. The amount of the collateral is required to be adjusted daily to
   reflect any price fluctuation in the value of the loaned securities. If the
   required market value of the collateral is less than the value of the loaned
   securities, the borrower is required to deliver additional collateral for the
   account of the Fund prior to the close of business on that day. The Fund has
   the right, under the lending agreement, to terminate the loan and recover the
   securities from the borrower with prior notice. The Fund is required to
   return the cash collateral to the borrower and could suffer a loss if the
   value of the collateral, as invested, has declined.


I. Repurchase Agreements

   With respect to repurchase agreements entered into by the Fund, the value of
   the underlying securities (collateral), including accrued interest, is
   required to be equal to or in excess of the repurchase price. The collateral
   for all repurchase agreements is held in safekeeping in the customer-only
   account of the Fund's custodian or a subcustodian of the Fund. The Fund's
   investment adviser, Pioneer Investment Management, Inc. (PIM), is responsible
   for determining that the value of the collateral remains at least equal to
   the repurchase price.


              Pioneer International Value Fund | Annual Report | 11/30/11     37
<PAGE>

2. Management Agreement

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 net assets up to $500 million and 0.75% of the excess
over $500 million. For the year ended November 30, 2011, the effective
management fee (excluding waivers and/or assumptions of expenses) was
equivalent to 0.85% of the Fund's average daily net assets.

PIM has contractually agreed to limit ordinary operating expenses to the extent
required to reduce Fund expenses to 1.45%, 2.35% and 2.35%, of the average
daily net assets attributable to Class A, Class B and Class C shares,
respectively. Fees waived and expenses reimbursed during the year ended
November 30, 2011 are reflected on the Statements of Operations. Class Y shares
do not have an expense limitation. These expense limitations are in effect
through April 1, 2013 for Class A, Class B and Class C shares. There can be no
assurance that PIM will extend the expense limitation agreement for a class of
shares beyond the date referred to above.

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 as administrative reimbursements. Included in
"Due to affiliates" reflected on the Statement of Assets and Liabilities is
$6,582 in management fees, administrative costs and certain other
reimbursements payable to PIM at November 30, 2011.


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 reimburses PIMSS for out-of-pocket expenses incurred by
PIMSS related to shareholder communications activities such as proxy and
statement mailings, outgoing phone calls and omnibus relationship contracts.
For the year ended November 30, 2011, such out-of-pocket expenses by class of
shares were as follows:

4. Distribution Plan

The Fund has adopted a Distribution Plan pursuant to Rule 12b-1 of the
Investment Company Act of 1940 with respect to its 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 also 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 or distribution services with regard to Class B and Class
C shares. Included in "Due to affiliates" reflected on the Statement of Assets
and Liabilities is $964 in distribution fees payable to PFD at November 30,
2011.

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 12 months of purchase. Class B shares 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. Shares
purchased as part of an exchange remain subject to any CDSC that applied to the
original purchase of those shares. There is no CDSC for Class Y shares.
Proceeds from the CDSCs are paid to PFD. For the year ended November 30, 2011,
CDSCs in the amount of $7,137 were paid to PFD.


5. Expense Offset Arrangements

The Fund has entered into certain expense offset arrangements with PIMSS which
may result in a reduction in the Fund's total expenses, due to interest earned
on cash held by PIMSS. For the year ended November 30, 2011, the Fund's
expenses were not reduced under such arrangements.


6. Forward Foreign Currency Contracts

At November 30, 2011, the Fund had entered into various forward foreign
currency contracts that obligate the Fund to deliver or take delivery of
currencies at specified future maturity dates. Alternatively, prior to the
settlement date of a forward foreign currency contract, the Fund may close out
such contract by entering into an offsetting contract. The average value of
contracts open during the year ended November 30, 2011 was $6,382,145,437. The
Fund had no outstanding settlement contracts at November 30, 2011.

7. Line of Credit Facility

The Fund, along with certain other funds in the Pioneer Family of Funds (the
Funds), participates 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 the amount available under
the facility or the limits set for borrowing by the Fund's prospectus and the
1940 Act. Interest on borrowings is payable at the higher of the London
Interbank Offered Rate (LIBOR) on the borrowing date plus 1.25% on an
annualized basis or the Federal Funds Rate on the borrowing date plus 1.25% on
an annualized basis. The Funds pay an annual commitment fee for this facility.
The commitment fee is allocated among participating Funds based on an
allocation schedule set forth in the credit agreement. For the year ended
November 30, 2011, the Fund had no borrowings under this agreement.

Report of Independent Registered Public Accounting Firm

To the Board of Trustees and Shareowners of
Pioneer International Value Fund:
--------------------------------------------------------------------------------
We have audited the accompanying statement of assets and liabilities of Pioneer
International Value Fund (the "Fund"), including the schedule of investments,
as of November 30, 2011, and the related statement of operations for the year
then ended, the statements of changes in net assets for each of the two years
in the period then ended, and the financial highlights for each of the periods
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 November 30, 2011, 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 International Value Fund at November 30, 2011, 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 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 investment adviser to
Pioneer International Value Fund (the Fund) pursuant to an investment advisory
agreement between PIM and the Fund. In order for PIM to remain the investment
adviser of the Fund, the Trustees of the Fund must determine annually whether
to renew the investment advisory agreement for the Fund.

The contract review process began in March 2011 as the Trustees of the Fund
agreed on, among other things, an overall approach and timeline for the
process. In July 2011, the Trustees approved the format of the contract review
materials and submitted their formal request to PIM to furnish information
necessary to evaluate the terms of the investment advisory agreement. The
contract review materials were provided to the Trustees in July 2011 and
September 2011. After reviewing and discussing the materials, the Trustees
submitted a request for additional information to PIM, and materials were
provided in response to this request. Meetings of the Independent Trustees of
the Fund were held in July, September, October, and November, 2011 to review
and discuss the contract review materials. In addition, the Trustees took into
account the information related to the Fund provided to the Trustees at each
regularly scheduled meeting.

At a meeting held on November 29, 2011, based on their evaluation of the
information provided by PIM and third parties, the Trustees of the Fund,
including the Independent Trustees voting separately, unanimously approved the
renewal of the investment advisory agreement for another year. In considering
the renewal of the investment advisory agreement, the Trustees considered
various factors that they determined were relevant, including the factors
described below. The Trustees did not identify any single factor as the
controlling factor in determining to approve the renewal of the agreement.

Nature, Extent and Quality of Services
The Trustees considered the nature, extent and quality of the services that had
been provided by PIM to the Fund, taking into account the investment objective
and strategy of the Fund. The Trustees reviewed the terms of the investment
advisory agreement. The Trustees also reviewed PIM's investment approach for
the Fund, its research process and its process for trade execution. The
Trustees considered the resources of PIM and the personnel of PIM who provide
investment management services to the Fund. The Trustees considered the
non-investment resources and personnel of PIM involved in PIM's services to the
Fund, including PIM's compliance and legal resources and personnel. The
Trustees also considered the substantial attention and high priority given by
PIM's senior management to the Pioneer fund complex. In addition, the


44    Pioneer International Value Fund | Annual Report | 11/30/11
<PAGE>

Trustees considered PIM's plans to increase resources in its investment
management function and other enhancements to PIM's advisory capabilities.

The Trustees considered that PIM supervises and monitors the performance of the
Fund's service providers and provides the Fund with personnel (including Fund
officers) and other resources that are necessary for the Fund's business
management and operations. The Trustees also considered that, as administrator,
PIM is responsible for the administration of the Fund's business and other
affairs. The Trustees considered the fees paid to PIM for the provision of
administration services.

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

Performance of the Fund
The Trustees considered the performance results of the Fund over various time
periods. They reviewed information comparing the Fund's performance with the
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 fourth quintile of its Morningstar
category for the one and three year periods ended June 30, 2011 and in the
fifth quintile of its Morningstar category for the five year period ended June
30, 2011. (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.) The Trustees discussed the Fund's performance record
and PIM's plan for improving the Fund's performance. The Trustees agreed that
they would closely monitor the implementation of PIM's plan for improving the
Fund's performance.

Management Fee and Expenses
The Trustees considered information showing the fees and expenses of the Fund
in comparison to the management fees and expense ratios of its peer group of
funds as classified by Morningstar and also to the expense ratios of a peer
group of funds selected on the basis of criteria determined by the Independent
Trustees for this purpose using data provided by Strategic Insight Mutual Trust
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, 2011 was in the third quintile relative to the management fees
paid by other funds in its Morningstar peer group for the comparable period.
The Trustees also considered the breakpoint in the management fee schedule and
the reduced fee rate on assets over $500 million. The Trustees considered that
the Fund's expense ratio for the twelve months ended June 30, 2011 was in


              Pioneer International Value Fund | Annual Report | 11/30/11     45
<PAGE>

the second quintile relative to its Strategic Insight peer group for the
comparable period.

The Trustees reviewed gross and net management fees charged by PIM to its
institutional and other clients, including publicly offered European funds,
U.S. registered investment companies (in a sub-advisory capacity), and
unaffiliated foreign and domestic separate accounts. The Trustees also
considered PIM's costs in providing services to the Fund and to its other
clients and considered the differences in management fees and profit margins
for PIM's Fund and non-Fund services. In evaluating the fees associated with
PIM's client accounts, the Trustees took into account the respective demands,
resources and complexity associated with the Fund and client accounts. The
Trustees noted that in some instances the fee rates for those clients were
lower than the management fee for the Fund and considered that, under the
investment advisory agreement with the Fund, PIM performs additional services
for the Fund that it does not provide to those other clients or services that
are broader in scope, including oversight of the Fund's other service providers
and activities related to compliance and the extensive regulatory and tax
regimes to which the Fund is subject. The Trustees also considered the
different entrepreneurial risks associated with PIM's management of the Fund
and the other client accounts. The Trustees concluded that the management fee
payable by the Fund to PIM was reasonable in relation to the nature and quality
of the services provided by PIM.

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
concluded that PIM's profitability with respect to the management of the Fund
was not unreasonable.

Economies of Scale
The Trustees considered PIM's views relating to economies of scale in
connection with the Pioneer Funds as fund assets grow and the extent to which
any such economies of scale are shared with funds and fund shareholders. The
Trustees recognize that economies of scale are difficult to identify and
quantify, rarely identifiable on a Fund-by-Fund basis, and that, among other
factors that may be relevant, are the following: fee levels, expense
subsidization, investment by PIM in research and analytical capabilities and
PIM's commitment and


46    Pioneer International Value Fund | Annual Report | 11/30/11
<PAGE>

resource allocation to the Funds. The Trustees noted that profitability also
may be an indicator of the availability of any economies of scale, although
profitability may vary for other reasons particularly, for example during the
recent difficult periods for financial markets, as the level of services was
maintained notwithstanding a significant decline in PIM's fee revenues from the
Funds. Accordingly, the Trustees concluded that economies of scale, if any,
were being appropriately shared with the Fund.

Other Benefits
The Trustees considered the other benefits to PIM from its relationship with
the Fund. The Trustees considered the character and amount of fees paid by the
Fund, other than under the investment advisory agreement, for services provided
by PIM and its affiliates. The Trustees further considered the revenues and
profitability of PIM's businesses other than the fund business. The Trustees
also considered the benefits to the Fund and 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 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
investment advisory agreement between PIM and the Fund, including the fees
payable thereunder, was fair and reasonable and voted to approve the proposed
renewal of the investment advisory agreement for the Fund.

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

                  SECTION I - POLICY PURPOSE AND APPLICABILITY

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

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

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

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

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

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.

Non-Audit Services
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 November 30, 2011 and 2010,
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 2011
and $8,290 in 2010.

(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.

The Fund's audit committee of the Board of Trustees has
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.

Item 5. Audit Committee of Listed Registrants

(a) If the registrant is a listed issuer as defined in Rule 10A-3
under the Exchange Act (17 CFR 240.10A-3), state whether
or not the registrant has a separately-designated standing
 audit committee established in accordance with Section
3(a)(58)(A) of the Exchange Act (15 U.S.C. 78c(a)(58)(A)).
If the registrant has such a committee, however designated,
identify each committee member. If the entire board of directors
is acting as the registrants audit committee as specified in
Section 3(a)(58)(B) of the Exchange Act (15 U.S.C. 78c(a)(58)(B)),
so state.

N/A

(b) If applicable, provide the disclosure required by Rule 10A-3(d)
under the Exchange Act (17 CFR 240.10A-3(d)) regarding an exemption
from the listing standards for audit committees.
