President's Letter

Dear Shareholder,

Over the past several years, many investors experienced positive returns across
most major asset classes. However, 2015 was a tale of two markets, with
favorable market conditions in the first half of the year, followed by an abrupt
slowdown and increased volatility beginning in August. The global markets were
challenged by significant economic cross-currents in different geographic
regions and industrial sectors. While the U.S. economy gradually improved,
growth slowed in China. Emerging markets struggled following a decline in
commodity prices, especially oil. While lower energy prices are good for the
consumer, there were ripple effects throughout the global economy.

Against this backdrop, the Standard & Poor's 500 Index rose by just 1.4% in
2015, international equity markets were essentially flat, and emerging market
equities fell sharply. Across U.S. fixed-income sectors, U.S. government and
investment-grade corporate bonds were fairly flat for the year, while high-yield
bonds, as measured by the Bank of America Merrill Lynch Master II High Yield
Index, posted a -4.9% total return.

Entering 2016, we see the possibility of a cyclical upswing, against an overall
economic backdrop that remains fragile and points towards structurally lower
growth. As always in a Presidential election year, political rhetoric has the
potential to impact U.S. sectors such as health care in 2016. Economies around
the world in both developed and emerging markets are experiencing deep
structural change. Geopolitical instability on many fronts, the rising risk of
policy mistakes, and market liquidity issues all increase the possibility of
sharp swings in asset values. In this environment, financial markets remain
vulnerable to unusual levels of volatility. While divergences among regions and
industries is an important theme, we are generally optimistic about the outlook
for the U.S. economy, which we expect will see modest growth.

Throughout Pioneer's history, we have believed in the importance of active
management. In periods of market volatility, we believe that the value of active
management is even more compelling. Our experienced and tenured investment teams
focus on identifying value across global markets using proprietary research,
careful risk management, and a long-term perspective. Our ongoing goal is to
produce compelling returns consistent with the stated objectives of our
investment products, and with our shareowners' expectations. We believe our
shareowners can benefit from the experience and tenure of our investment teams
as well as the insights generated from our extensive research process.

2 Pioneer International Equity Fund | Annual Report | 11/30/15


As always, and particularly during times of market uncertainty, we encourage you
to work with your financial advisor to develop an overall investment plan that
addresses both your short- and long-term goals, and to implement such a plan in
a disciplined manner.

We greatly appreciate the trust you have placed in us and look forward to
continuing to serve you in the future.

Sincerely,

/s/ Lisa M. Jones

Portfolio Management Discussion | 11/30/15

In the follow interview, Madelynn Matlock discusses the market environment for
international equities and the factors that influenced the performance of
Pioneer International Equity Fund* during the 12-month period ended November 30,
2015. Ms. Matlock, a senior vice president and a portfolio manager at Pioneer,
and Marco Pirondini, Executive Vice President, Head of Equities, U.S., and a
portfolio manager at Pioneer, are responsible for the day-to-day management of
the Fund.

Q    How did Pioneer International Equity Fund perform for during the 12-month
     period ended November 30, 2015?

A    Pioneer International Equity Fund's Class A shares returned -1.69% at net
     asset value during the 12-month period ended November 30, 2015, while the
     Fund's benchmark, the Morgan Stanley Capital International (MSCI) Europe,
     Australasia, Far East (EAFE) ND Index1 (the MSCI Index) returned -2.94%.
     During the same period, the average return of the 410 mutual funds in
     Lipper's International Multi-Cap Core Funds category was -3.32%, and the
     average return of the 791 mutual funds in Morningstar's Foreign Large Blend
     Funds category was -3.26%.

Q    How would you characterize the investment environment for international
     equities during the 12-month period ended November 30, 2015?

A    The global economy faced several headwinds during the 12-month reporting
     period, all of which led to considerable volatility in international equity
     markets. Geopolitical tensions in the Middle East, Greece's standoff with
     its creditors, China's slowing economy, and the destabilizing influence of
     the dramatic decline in commodity prices were among the factors
     contributing to a stagnating global economic growth picture and the
     resulting uncertainty and market volatility.

4 Pioneer International Equity Fund | Annual Report | 11/30/15


     Against that backdrop, U.S. stocks outperformed international stocks during
     the 12-month period (the Standard & Poor's 500 Index returned 2.76% for the
     12 months ended November 30, 2015, while the MSCI World Ex-U.S. Index, a
     measure of non-U.S. developed markets, returned -4.55%). The emerging
     markets were the biggest laggards during the period, as the MSCI Emerging
     Markets ND Index returned -16.99%. Elsewhere in international equity
     markets, the Pacific Rim, with relatively strong performance from Japan,
     posted slightly positive returns, while Europe struggled (the (MSCI Pacific
     Index and MSCI Europe Index returned 0.15% and -4.06%, respectively, during
     the period).

     From a sector perspective, information technology, consumer staples, and
     health care were the top performers during the period, while energy and
     utilities stocks turned in negative performance, reflecting the sharp
     decline in oil prices and slowing consumer demand.

     While international equity markets faced many challenges during the period,
     we saw the 12 months as a time to uncover new investment opportunities. In
     our experience, investors generally tend to lose sight of positive
     long-term fundamentals during periods of uncertainty and heightened market
     volatility, and often sell indiscriminately. When that happens, such
     sell-offs can bring stock prices more in line with what we are willing to
     pay based on their long-term value. China's surprise currency devaluation
     in August 2015, and the historic sell-off in global equities that ensued,
     was, in our view, an opportune time to uncover stocks that had become more
     reasonably priced, or even compellingly cheap.

Q    Which of your investment strategies contributed to the Fund's
     outperformance relative to the benchmark MSCI EAFE ND Index during the
     12-month period ended November 30, 2015?

A    Positive stock selection was the main driver of the Fund's performance
     relative to the benchmark during the period. In addition, the Fund's
     relative results benefitted from some incremental return from sector
     weightings and regional allocations.

     From a sector allocation perspective, our decisions to overweight the
     portfolio in the outperforming information technology sector and to
     underweight the struggling energy sector aided benchmark-relative returns.
     Within the financials sector, our emphasis on owning insurance companies
     and real estate-focused companies, while limiting investments in banks, was
     also beneficial for the Fund's benchmark-relative performance.

                  Pioneer International Equity Fund | Annual Report | 11/30/15 5


     As for regional/country allocations, the portfolio's greater-than-benchmark
     exposure to Japan was a positive factor in the Fund's relative returns, as
     the Japanese stock market turned in reasonably solid performance during the
     period. We have been encouraged by Japan's aggressive monetary policies and
     shareholder-friendly market reforms, which are helping to improve company
     profitability and support equity prices in the country.

     With regard to individual stock selections, positive benchmark-relative
     returns for the 12-month period derived largely from the Fund's positions
     in lesser-known, more mid-sized companies. For example, the Fund's shares
     of Sundrug, a drugstore chain, benefited from an easing of drug-dispensing
     regulations in Japan as well as the waning of the one-time shock caused by
     an increase in the country's value-added tax. We continue to believe
     Sundrug is in a good position to benefit from its retail network
     capabilities. Another strong performer in the portfolio during the period
     was Gerresheimer, a German manufacturer of packaging products for
     medication and drug delivery devices made of special-purpose glass and
     plastics, such as insulin pens and asthma inhalers. Gerresheimer saw both
     strong organic growth and corresponding revenue growth during the 12-month
     period. In addition, the Fund's investment in Murata, a manufacturer of
     electronics used to enable wireless communications for smartphones and
     other products, was a beneficiary of the growth in global smartphone usage.
     Murata's stock price also rose on news of the company's decision to expand
     its reach into the so-called "Internet of Things" -- connecting
     thermostats, appliances, and other devices to computers and smartphones.

Q    Which of your investment strategies detracted the most from the Fund's
     performance during the 12-month period ended November 30, 2015?

A    Exposure to the energy sector represented the largest drag on the Fund's
     performance during the period. Energy was the poorest-performing market
     sector over the 12 months, as the sharp decline in oil prices and the
     refusal of the OPEC (Organization of the Petroleum Exporting Countries)
     cartel to cut production to bolster prices created a ripple effect
     throughout the global economy. Oil exploration-and-production companies,
     which have reduced capital spending given the supply/demand imbalance, felt
     the greatest impact.

     While the Fund held a lower-than-benchmark weighting in energy during the
     period, any exposure to the sector proved to be a headwind for absolute
     returns. One portfolio position in energy that detracted from the Fund's

6 Pioneer International Equity Fund | Annual Report | 11/30/15


     performance during the period was Canadian firm Encana, which not only
     struggled due to the impact of falling oil revenues, but also was hurt by
     management's ill-timed offer to buy an oil producer in the Texas shale
     area.

     In health care, the Fund's position in Fagron, a pharmaceutical compounding
     company dedicated to creating customized medications, also detracted from
     returns. We purchased the shares of Fagron last spring, but the company
     soon ran into unforeseen contract problems with a recently acquired firm,
     which adversely affected Fagron's earnings for the third quarter of 2015.
     We sold the Fund's shares after news of the troubled negotiations surfaced.

     Finally, a holding in Japanese industrial conglomerate Hitachi hurt the
     Fund's returns during the period. Hitachi saw weaker-than-expected revenue
     growth due to cutbacks in capital expenditures in the manufacturing sector
     worldwide. However, we remain confident in management's ability to promote
     corporate growth opportunities for Hitachi. We still held shares of both
     Hitachi and Encana in the Fund's portfolio as of period end.

Q    Did the Fund have any derivatives exposure during the 12-month period ended
     November 30, 2015, and did the exposure have an effect on performance?

A    Yes. We invested in currency forwards and futures contracts during the
     period. In addition, we used total return swaps in an attempt to hedge the
     difference between the performance of Japan's Nikkei 400 Index, which was
     introduced in 2014, and the TOPIX (Tokyo Stock Price Index) Index. The use
     of derivatives, particularly the hedge, which favored the relative
     outperformance of the Nikkei 400, was slightly accretive for the Fund's
     performance during the reporting period.

Q    What is your outlook as we enter 2016?

A    Our near-term view is guarded, as we see some risks in the global
     landscape. Chief among our concerns are geopolitical tensions in the Middle
     East, acts of terrorism, and the dramatic decline in commodity

                  Pioneer International Equity Fund | Annual Report | 11/30/15 7


     prices, which has added to economic and political instability in countries
     that depend on commodity-based revenue - particularly Brazil. However, we
     also see reasons to be optimistic.

     The European economy appears to have bottomed, and the European Central
     Bank's quantitative easing program seems to be moving the region towards a
     recovery path. The Japanese economy has seen a slower pace of growth,
     mainly due to decreased exports to China. Yet, we also see continued growth
     in consumer spending, supported by increases in real wages, as well as a
     sustained recovery in corporate earnings of Japanese companies. Both
     Japanese and European markets have benefited from the U.S. economic
     recovery, which has received support from improving employment figures and
     income levels. In the emerging markets, we continue to see weakness in
     Latin America, offset by pockets of strength in Asia. We believe the
     emerging markets may be getting close to hitting a bottom in terms of
     relative performance, but we expect market volatility to remain high.

     Regardless of market conditions, we will continue to abide by our research-
     driven investment approach, which is rooted in evaluating and choosing
     stocks that we believe have good return potential -- and then not
     overpaying for that potential. We evaluate every company's return on
     invested capital compared with what they must pay for that capital, and we
     favor owning companies that are either adding value on a consistent basis,
     or which have the potential to improve their returns over time.

     We also seek to take advantage of long-running secular trends that may lead
     to higher returns in the future, and try to avoid what we consider negative
     trends that might drag on the performance of even well-managed companies.
     Aging populations, slower population growth, carbon-limiting strategies,
     the sharing (or access) economy, and increased travel demand in developed
     countries are examples of secular trends that we think are creating new
     investments opportunities for the Fund.

*    Note to Shareholders: Effective November 1, 2015, Pioneer International

Index Definition
--------------------------------------------------------------------------------
The MSCI EAFE ND Index is an unmanaged, 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 12-14.

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 the contractual expense limitation currently in
effect through April 1, 2016, for Class A shares. There can be no assurance that
Pioneer will extend the expense limitation 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.

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 C shares held for less than one year are also subject to a 1% contingent
deferred sales charge (CDSC). "If Held" results represent the percent change in
net asset value per share. Returns would have been lower had sales charges been
reflected. All results are historical and assume the reinvestment of dividends
and capital gains. Other share classes are 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 the contractual expense limitation currently in

Pioneer will extend the expense limitation beyond such time. Please see the

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 on April 16, 2009, 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. For the period beginning
April 16, 2009, the actual performance of Class Y shares is reflected. 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.

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


*    Expenses are equal to the Fund's annualized net expense ratio of 1.45%,
     2.35% and 1.04% for class A, C and Y shares, 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.

Notes to Financial Statements | 11/30/15

1. Organization and Significant Accounting Policies

Pioneer International Equity Fund (formerly 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 offered three classes of shares designated as Class A, Class C and
Class Y shares. Class B shares were converted to Class A shares as of the close
of business on November 10, 2014. 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 of Trustees 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.

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.

The following is a summary of significant accounting policies followed by the
Fund in the preparation of its financial statements:

A.   Security Valuation

     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.

                 Pioneer International Equity Fund | Annual Report | 11/30/15 31


     Equity securities that have traded on an exchange are valued by using the
     last sale price on the principal exchange where they are traded. Equity
     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 or, if both last bid and asked prices
     are not available, at the last quoted bid price. Last sale and bid and
     asked prices are provided by independent third party pricing services. In
     the case of equity securities not traded on an exchange, prices are
     typically determined by independent third party pricing services using a
     variety of techniques and methods.

     The principal exchanges and markets for non-U.S. equity 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 Fund uses a fair
     value model developed by an independent pricing service to value non-U.S.
     equity securities. On a daily basis, the pricing service recommends
     changes, based on a proprietary model, to the closing market prices of each
     non-U.S. security held by the Fund to reflect the security's fair value at
     the time the Fund determines its net asset value. The Fund applies these
     recommendations in accordance with procedures approved by the Board of
     Trustees.

     Swap contracts, including interest rate swaps, caps and floors (other than
     centrally cleared swap contracts) are valued at the dealer quotations
     obtained from reputable International Swap Dealer association members.
     Centrally cleared swaps are valued at the daily settlement price provided
     by the central clearing counterparty.

     Futures contracts are generally valued at the closing settlement price
     established by the exchange on which they are traded.

     Forward foreign currency exchange contracts are valued daily using the
     foreign exchange rate or, for longer term forward contract positions, the
     spot currency rate, in each case provided by a third party pricing service.
     Contracts whose forward settlement date falls between two quoted days are
     valued by interpolation.

     Shares of open-end registered investment companies (including money market
     mutual funds) are valued at such funds' net asset value. Repurchase
     agreements are valued at par. Cash may include overnight time deposits at
     approved financial institutions.

     Securities for which independent pricing services are unable to supply
     prices or for which market prices and/or quotations are not readily
     available or are considered to be unreliable are valued by a fair valuation
     team comprised of certain personnel of Pioneer Investment Management, Inc.
     (PIM), the Fund's

32 Pioneer International Equity Fund | Annual Report | 11/30/15


     investment adviser, pursuant to procedures adopted by the Fund's Board of
     Trustees. PIM's fair valuation team uses fair value methods approved by the
     Valuation Committee of the Board of Trustees. PIM's fair valuation team is
     responsible for monitoring developments that may impact fair valued
     securities and for discussing and assessing fair values on an ongoing
     basis, and at least quarterly, with the Valuation Committee of the Board of
     Trustees.

     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. 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 significantly from exchange prices and
     such differences could be material.

     At November 30, 2015, there were no securities valued using fair value
     methods (other than securities valued using prices supplied by independent
     pricing services or broker-dealers).

B.   Investment Income and Transactions

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

     Security transactions are recorded as of trade date. Gains and losses on
     sales of investments are calculated on the identified cost method for both
     financial reporting and federal income tax purposes.

C.   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

                 Pioneer International Equity Fund | Annual Report | 11/30/15 33


     investments are not segregated in the Statement of Operations from the
     effects of changes in the market price of those securities but are included
     with the net realized and unrealized gain or loss on investments.

D.   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 appreciation or depreciation
     are recorded in the Fund's financial statements. The Fund records realized
     gains and losses at the time a contract 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).

E.   Federal Income Taxes

     It is the Fund's policy to comply with the requirements of the Internal
     Revenue Code applicable to regulated investment companies and to distribute
     all of its net taxable income and net realized capital gains, if any, to
     its shareowners. Therefore, no provision for federal income taxes is
     required. As of November 30, 2015, the Fund did not accrue any interest or
     penalties with respect to uncertain tax positions, which, if applicable,
     would be recorded as an income tax expense in the Statement of Operations.
     Tax returns filed within the prior three years remain subject to
     examination by federal and state tax authorities.

     In addition to meeting the requirements of the Internal Revenue Code, the
     Fund may be required to pay local taxes on the recognition of capital gains
     and/or the repatriation of foreign currencies in certain countries. During
     the year ended November 30, 2015, the Fund paid no such taxes.

     The amount and character of income and capital gain distributions to
     shareowners are determined in accordance with federal income tax rules,
     which may differ from U.S. generally accepted accounting principles.
     Distributions in excess of net investment income or net realized gains are
     temporary overdistributions for financial statement purposes resulting from
     differences in the recognition or classification of income or distributions
     for financial statement and tax purposes. Capital accounts within the
     financial statements are adjusted for permanent book/tax differences to
     reflect tax character, but are not adjusted for temporary differences.

34 Pioneer International Equity Fund | Annual Report | 11/30/15


     At November 30, 2015, the Fund reclassified $488,233 to increase
     undistributed net investment income and $488,233 to increase accumulated
     net realized loss on investments, futures contracts, swap contracts and
     foreign currency transactions to reflect permanent book/tax differences.
     These adjustments have no impact on net assets or the results of
     operations.

     At November 30, 2015, the Fund had a net capital loss carryforward of
     $109,242,908, which will expire in 2017 if not utilized.

     During the year ended November 30, 2015, a capital loss carryforward of
     $2,596,038 was utilized to offset net realized gains by the Fund.

     The tax character of distributions paid during the years ended November 30,
     2015, and November 30, 2014, was as follows:



     ---------------------------------------------------------------------------
                                                     2015                   2014
     ---------------------------------------------------------------------------
                                                                
     Distribution paid from:
     Ordinary income                          $11,143,703             $8,013,259

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


     The following shows the components of distributable earnings on a federal
     income tax basis at November 30, 2015:



     ---------------------------------------------------------------------------
                                                                            2015
     ---------------------------------------------------------------------------
                                                                
     Distributable earnings:
     Undistributed ordinary income                                 $   2,168,983
     Capital loss carryforward                                      (109,242,908)
     Net unrealized appreciation                                       1,274,078
     ---------------------------------------------------------------------------
        Total                                                      $(105,799,847)
     ===========================================================================


     The difference between book-basis and tax-basis net unrealized appreciation
     is attributable to the tax deferral of losses on wash sales and adjustments
     relating to PFICs.

F.   Fund Shares

     The Fund records sales and repurchases of its shares as of trade date.
     Pioneer Funds Distributor, Inc. (PFD), the principal underwriter for the
     Fund and a wholly owned indirect subsidiary of UniCredit S.p.A.
     (UniCredit), earned $13,180 in underwriting commissions on the sale of
     Class A shares during the year ended November 30, 2015.

G.   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.

                 Pioneer International Equity Fund | Annual Report | 11/30/15 35


     Distribution fees are calculated based on the average daily net asset value
     attributable to Class A 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 Fund's transfer agent, 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 C and Class Y shares can
     reflect different transfer agent and distribution expense rates.

H.   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 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.

I.   Repurchase Agreements

     Repurchase agreements are arrangements under which the Fund purchases
     securities from a broker-dealer or a bank, called the counterparty, upon
     the agreement of the counterparty to repurchase the securities from the
     Fund at a later date, and at a specific price, which is typically higher
     than the purchase price paid by the Fund. The securities purchased serve as
     the Fund's collateral for the obligation of the counterparty to repurchase
     the securities. The value of the 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, PIM is responsible for determining
     that the value of the collateral remains at least equal to the repurchase
     price. In the event of a default by the counterparty, the Fund is entitled
     to sell the securities, but the Fund may not be able to sell them for the
     price at which they were purchased, thus causing a loss to the Fund.
     Additionally, if the counterparty becomes insolvent, there is some risk
     that the Fund will not have a right to the securities, or the immediate
     right to sell the securities. As of and for the year ended November 30,
     2015, the Fund had no open repurchase agreements.

J.   Futures Contracts

     The Fund may enter into futures transactions in order to attempt to hedge
     against changes in interest rates, securities prices and currency exchange
     rates or to seek to increase total return. Futures contracts are types of
     derivatives. All futures contracts entered into by the Fund are traded on a
     futures exchange. Upon entering into a futures contract, the Fund is
     required to deposit with a broker an amount of cash or securities equal to
     the minimum "initial margin" requirements of the associated futures
     exchange. Subsequent payments for futures contracts ("variation margin")
     are paid or received by the Fund, depending on the daily fluctuation in the
     value of the contracts, and are recorded by the Fund as unrealized gains or
     losses. When the contract is closed, the Fund realizes a gain or loss equal
     to the difference between the opening and closing value of the contract as
     well as any fluctuation in foreign currency exchange rates where
     applicable. Futures contracts are subject to market risk, interest rate
     risk and currency exchange rate risk. Changes in value of the contracts may
     not directly correlate to the changes in value of the underlying
     securities. With futures, there is minimal counterparty credit risk to the
     Fund since futures are exchange-traded and the exchange's clearinghouse, as
     counterparty to all exchange-traded futures, guarantees the futures against
     default. The average value of contracts open during the year ended November
     30, 2015 was $(6,976,290). At November 30, 2015, the Fund had no open
     futures contracts.

K.   Total Return Swap Agreements

     The Fund may enter into a total return swap contracts to attempt to manage
     and/or gain exposure to a security or market. Pursuant to a total return
     swap contracts, the Fund negotiates with a counterparty to exchange a
     periodic stream of payments. One party makes payments based on the total
     return of a reference asset (such as a security or a basket of securities
     or securities index), and in return receives fixed or floating rate
     interest payments. The total return of the reference asset typically
     includes appreciation or depreciation on the reference asset, plus any
     interest or dividend payments. To the extent that the total return of the
     reference asset exceeds or falls short of the offsetting interest rate
     obligation, the Fund will receive a payment from or make a payment to the
     counterparty.

     Total return swap contracts are marked-to-market daily using valuations
     supplied by independent sources and the change in value, if any, is
     recorded as unrealized appreciation or depreciation in the Statement of
     Assets and Liabilities. Payments received or made are recorded as realized
     gains or losses in the Statement of Operations. Total return swap contracts
     are subject to counterparty risk and unanticipated movements in value of
     exchange rates, interest rates, securities or the index.

                 Pioneer International Equity Fund | Annual Report | 11/30/15 37


     The average value of swap contracts open during the year ended November 30,
     2015 was $199,082. At November 30, 2015, the Fund had no open total return
     swap contracts.

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, 2015, 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 contractually agreed to limit ordinary operating expenses to the extent
required to reduce Fund expenses to 1.45% and 2.35%, of the average daily net
assets attributable to Class A and Class C shares, respectively. These expense
limitations are in effect through April 1, 2017. There can be no assurance that
PIM will extend the expense limitation agreement for a class of shares beyond
the date referred to above. Fees waived and expenses reimbursed during the year
ended November 30, 2015 are reflected on the Statement of Operations. Class Y
shares do not have an expense limitation.

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
$20,858 in management fees, administrative costs and certain other
reimbursements payable to PIM at November 30, 2015.

3. Transfer Agent

Prior to November 2, 2015, Pioneer Investment Management Shareholder Services,
Inc. (PIMSS), a wholly owned indirect subsidiary of UniCredit, provided
substantially all transfer agent and shareowner services to the Fund at
negotiated rates.

Effective November 2, 2015, Boston Financial Data Services serves as the
transfer agent to the Fund at negotiated rates.

In addition, the Fund reimbursed the transfer agent for out-of-pocket expenses
incurred by the transfer agent related to shareholder communications activities
such as proxy and statement mailings, outgoing phone calls and omnibus
relationship contracts. For the year ended November 30, 2015, such out-of-pocket
expenses by class of shares were as follows:



--------------------------------------------------------------------------------
Shareholder Communications:
--------------------------------------------------------------------------------
                                                                     
Class A                                                                 $101,950
Class C                                                                   12,900
--------------------------------------------------------------------------------
  Total                                                                 $114,850
--------------------------------------------------------------------------------


38 Pioneer International Equity Fund | Annual Report | 11/30/15


Included in "Due to affiliates" reflected on the Statement of Assets and
Liabilities is $41,150 in transfer agent fees and out-of-pocket reimbursements
payable to PIMSS at November 30, 2015.

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 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 C shares. The fee for 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 C shares. Included in "Due to affiliates" reflected on the
Statement of Assets and Liabilities is $4,292 in distribution fees payable to
PFD at November 30, 215.

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. Redemptions of Class C shares within 12 months 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, 2015, CDSCs in the amount of $16,058 were paid to PFD.

5. Expense Offset Arrangements

The Fund entered into certain expense offset arrangements with PIMSS. For the
year ended November 30, 2015, the Fund's expenses were not reduced under such
arrangements.

6. Forward Foreign Currency Contracts

During the year ended November 30, 2015, 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 forward foreign currency contracts open during the year ended November
30, 2015, was $(423,061). There are no open forward foreign currency contracts
at November 30, 2015.

                 Pioneer International Equity Fund | Annual Report | 11/30/15 39


7. Line of Credit Facility

The Fund, along with certain other funds in the Pioneer Family of Funds (the
Funds), participates in a 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. The
credit facility in effect until June 9, 2015, was in the amount of $215 million.
As of June 9, 2015, the facility is in the amount of $240 million. Under such
facility, depending on the type of loan, interest on borrowings is payable at
the London Interbank Offered Rate (LIBOR) plus 0.85% on an annualized basis, or
the Alternate Base Rate, which is the greater of (a) the facility's
administrative agent's daily announced prime rate on the borrowing date, (b) 2%
plus the Federal Funds Rate on the borrowing date and (c) 2% plus the overnight
Eurodollar rate on the borrowing date. The Funds pay an annual commitment fee to
participate in a credit 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, 2015, the Fund had no borrowings
under the credit facility.

8. Additional Disclosures about Derivative Instruments and Hedging Activities

The Fund's use of derivatives subjects it to the following risks:

Interest rate risk relates to the fluctuations in the value of interest-bearing
securities due to changes in the prevailing levels of market interest rates.

Credit risk relates to the ability of the issuer of a financial instrument to
make further principal or interest payments on an obligation or commitment that
it has to the Fund.

Foreign exchange rate risk relates to fluctuations in the value of an asset or
liability due to changes in currency exchange rates.

Equity risk relates to the fluctuations in the value of financial instruments as
a result of changes in market prices (other than those arising from interest
rate risk or foreign exchange risk), whether caused by factors specific to an
individual investment, its issuer, or all factors affecting all instruments
traded in a market or market segment.

40 Pioneer International Equity Fund | Annual Report | 11/30/15


Commodity risk relates to the risk that the value of a commodity or commodity
index will fluctuate based on increases or decreases in the commodities market
and factors specific to a particular industry or commodity.

The effect of derivative instruments (not considered to be hedging instruments
for accounting disclosure purposes) on the Statement of Operations by risk
exposure at November 30, 2015, was as follows:

Report of Independent Registered Public Accounting Firm

To the Board of Trustees of Pioneer Series Trust VIII and the Shareowners of
Pioneer International Equity Fund (formerly, Pioneer International Value Fund):
--------------------------------------------------------------------------------
We have audited the accompanying statement of assets and liabilities, including
the schedule of investments, of Pioneer International Equity Fund (formerly,
Pioneer International Value Fund), as of November 30, 2015, and the related
statement of operations for the year then ended and the statements of changes in
net assets and the financial highlights for each of the two years in the period
then ended. 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. The financial highlights for the years ended November 30, 2013, 2012,
and 2011 were audited by other auditors. Those auditors expressed an unqualified
opinion on those financial statements and financial highlights in their report
dated January 24, 2014.

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. The Fund
is not required to have, nor were we engaged to perform, an audit of its
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, assessing the accounting principles
used and significant estimates made by management, as well as evaluating the
overall financial statement presentation. Our procedures included confirmation
of securities owned as of November 30, 2015, by correspondence with the
custodian and brokers; where replies were not received from brokers, we
performed other auditing procedures. 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 Equity Fund as of November 30, 2015, the results of its
operations for the year then ended and the changes in its net assets and the
financial highlights for each of the two years in the period then ended, in
conformity with accounting principles generally accepted in the United States of
America.

Additional Information (unaudited)

PIM, the Fund's investment adviser, is currently an indirect, wholly owned
subsidiary of UniCredit. On November 11, 2015, UniCredit announced that it
signed a binding master agreement with Banco Santander and affiliates of Warburg
Pincus and General Atlantic (the "Private Equity Firms") with respect to Pioneer
Investments ("Pioneer") and Santander Asset Management ("SAM") (the
"Transaction").

The Transaction, as previously announced by UniCredit, will establish a holding
company, with the name Pioneer Investments, to be owned by UniCredit (50%) and
the Private Equity Firms (50% between them). The holding company will control
Pioneer's U.S. operations, including the Adviser. The holding company also will
own 66.7% of Pioneer's and SAM's combined operations outside the U.S., while
Banco Santander will own directly the remaining 33.3% stake. The closing of the
Transaction is expected to happen in 2016, subject to certain regulatory and
other approvals.

Under the Investment Company Act of 1940, completion of the Transaction will
cause the Fund's current investment advisory agreement with PIM to terminate.
Accordingly, the Fund's Board of Trustees will be asked to approve a new
investment advisory agreement. If approved by the Board, the Fund's new
investment advisory agreement will be submitted to the shareholders of the Fund
for their approval.

                 Pioneer International Equity Fund | Annual Report | 11/30/15 43


Approval of Investment Advisory Agreement

Pioneer Investment Management, Inc. (PIM) serves as the investment adviser to
Pioneer International Equity Fund (formerly, 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 January 2015 as the Trustees of the Fund
agreed on, among other things, an overall approach and timeline for the process.
Contract review materials were provided to the Trustees in March 2015 and July
2015. Supplemental contract review materials were provided to the Trustees in
September 2015. In addition, the Trustees reviewed and discussed the Fund's
performance at regularly scheduled meetings throughout the year and took into
account other information related to the Fund provided to the Trustees at
regularly scheduled meetings in connection with the review of the Fund's
investment advisory agreement.

In March 2015, the Trustees, among other things, discussed the memorandum
provided by Fund counsel that summarized the legal standards and other
considerations that are relevant to the Trustees in their deliberations
regarding the renewal of the investment advisory agreement, and reviewed and
discussed the qualifications of the investment management teams, as well as the
level of investment by the Fund's portfolio managers in the Fund. In July 2015,
the Trustees, among other things, reviewed the Fund's management fee and total
expense ratios, the financial statements of PIM and its parent companies, the
profitability analyses provided by PIM, and possible economies of scale. The
Trustees also reviewed the profitability of the institutional business of PIM
and PIM's affiliate, Pioneer Institutional Asset Management, Inc. (together with
PIM, "Pioneer"), as compared to that of PIM's fund management business, and
considered the differences between the fees and expenses of the Fund and the
fees and expenses of Pioneer's institutional accounts, as well as the different
services provided by PIM to the Fund and by Pioneer to the institutional
accounts. The Trustees further considered contract review materials in September
2015.

At a meeting held on September 15, 2015, 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 approving the
renewal of the investment advisory agreement, the Trustees

44 Pioneer International Equity Fund | Annual Report | 11/30/15


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 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 reviewed the amount of non-Fund assets managed by the portfolio
managers of 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 noted the substantial
attention and high priority given by PIM's senior management to the Pioneer fund
complex.

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

In considering the Fund's performance, the Trustees regularly review and discuss
throughout the year data prepared by PIM and information comparing the Fund's
performance with the performance of its peer group of funds as classified by
each of Morningstar, Inc. (Morningstar) and Lipper, and with the performance of
the Fund's benchmark index. They also discuss the Fund's performance with PIM on
a regular basis. The Trustees' regular reviews and discussions were factored
into the Trustees' deliberations concerning the renewal of the advisory
agreement.

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

                 Pioneer International Equity Fund | Annual Report | 11/30/15 45


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. In all quintile rankings referred to below, first quintile is most
favorable to the Fund's shareowners.

The Trustees considered that the Fund's management fee for the most recent
fiscal year 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 above a certain asset level. The Trustees considered that the
expense ratio of the Fund's Class A shares for the most recent fiscal year was
in the fourth quintile relative to its Morningstar peer group and in the fourth
quintile relative its Strategic Insight peer group, in each case for the
comparable period. The Trustees considered that the expense ratio of the Fund's
Class Y shares for the most recent fiscal year was in the fourth quintile
relative to its Morningstar peer group and in the fourth quintile relative its
Strategic Insight peer group, in each case for the comparable period. The
Trustees noted that PIM was waiving fees and/or reimbursing expenses in order to
limit the ordinary operating expenses of the Fund. The Trustees noted the Fund's
relatively small asset size compared to most of the other funds in its peer
groups, and that the Fund has not been able to take advantage of the economies
of scale afforded by greater asset size. The Trustees considered the impact of
transfer agency, sub-transfer agency, and other non-management fee expenses on
the expense ratios of the Fund, and noted the impact of expenses relating to
small accounts and omnibus accounts on transfer and sub-transfer agency expenses
generally. The Trustees considered that such non-management fee operating
expenses generally are spread over a smaller asset base than the other funds in
the peer group, which results in these fees being significantly higher as a
percentage of assets. The Trustees noted that they separately review the Fund's
transfer agency, sub-transfer agency and intermediary arrangements.

The Trustees reviewed management fees charged by Pioneer to institutional and
other clients, including publicly offered European funds sponsored by affiliates
of Pioneer, unaffiliated 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 Pioneer's
costs in providing services to the other clients and considered the differences
in management fees and profit margins for Fund and non-Fund services. In
evaluating the fees associated with Pioneer'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

46 Pioneer International Equity Fund | Annual Report | 11/30/15


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 Pioneer's
management of 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
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
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
noted the breakpoint in the management fee schedule. The Trustees recognize that
economies of scale are difficult to identify and quantify, 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 resource allocation to the Fund. 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 including reductions in
expenses. The Trustees concluded that economies of scale, if any, were being
appropriately shared with the Funds.

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. Pioneer is the
principal U.S. asset management business of Pioneer Global Asset Management, the
worldwide asset management business of UniCredit Group, which manages over $150
billion in assets (including the Funds). Pioneer and the Funds receive
reciprocal intangible benefits from the relationship, including mutual brand
recognition and, for the Funds, direct and indirect access to the resources of a
large global asset manager. The Trustees concluded that any such benefits
received by Pioneer as a result of its relationship with the Funds were
reasonable and their consideration of the advisory agreement between the Fund
and PIM and the fees thereunder were unaffected by Pioneer's possible receipt of
any such intangible benefits.

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.

  pre-approved service subcategories set forth above must be specifically
  approved by the Audit Committee.

under the Exchange Act (17 CFR 240.13a-15(b) or 240.15d-15(b)).
