President's Letter

Dear Shareowner,

While investors were greeted with a challenging market environment for the first
several weeks of 2016, the U.S. market generated modest single-digit returns for
both stocks and bonds through September 30, 2016 (the Bloomberg Barclays
Aggregate Bond Index was up by 5.8% through September 30, 2016, and the Standard
& Poor's 500 Index was up by 7.8%). Yet, it is becoming increasingly clear that
the investment landscape is undergoing significant change. For the past eight
years, global central banks have been the dominant force in the markets by
maintaining government bond yields at close to zero in an effort to stimulate
economic growth. With little room to lower rates further, however, central banks
may be losing their effectiveness. Many economies around the world are
experiencing slow growth as they face a variety of challenges, including the
shifting geopolitics driving "Brexit" - the United Kingdom's pending exit from
the European Union - as well as related movements in Europe, limited
productivity gains, aging populations, and transitioning economic models in
China and other emerging markets. In the United States, gross domestic product
(GDP) grew at a rate of approximately 1.2% in the first half of 2016, but GDP
growth registered a strong uptick in the third quarter of the year, driven
primarily by U.S. consumers.

Investors currently face a difficult environment. Government bond yields, as
noted earlier, had been near zero for most of the year and offered minimal
opportunity to produce income. However, recent developments such as the Federal
Reserve's decision to increase the Federal funds rate before the end of 2016
have driven yields slightly higher. The central bank-driven bull market in
riskier assets has pushed up valuations towards historic highs in the equity and
investment-grade and high-yield corporate bond markets. Central banks have
pledged to move gradually to normalize interest-rate policies as the global
economy recovers, but it may take many years for this historic credit cycle to
unwind. Politics may also influence markets or investor sentiment given the
current global political landscape. Donald Trump's victory in the November U.S.
presidential election seems to have sparked a late-year market rally, given the
pro-growth proposals he promoted on the campaign trail, but it is unclear just
how many of his policy initiatives will be implemented. In addition, continued
challenges with Brexit and other geopolitical issues have the potential to
increase market volatility going forward. Against this backdrop, investors are
likely to face ongoing challenges when it comes to finding opportunities for
both income and capital appreciation, and while much has been made of passive
investing, we believe all investment decisions are active choices.

Portfolio Management Discussion | 11/30/16

In the following 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, 2016. 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 the Fund perform during the 12-month period ended November 30, 2016?

A   Pioneer International Equity Fund's Class A shares returned -4.70% at net
    asset value during the 12-month period ended November 30, 2016, while the
    Fund's benchmark, the Morgan Stanley Capital International (MSCI) Europe,
    Australasia, Far East (EAFE) ND Index1, returned -3.66%. During the same
    period, the average return of the 445 mutual funds in Lipper's
    International Multi-Cap Core Funds category was -3.03%, and the average
    return of the 767 mutual funds in Morningstar's Foreign Large Blend Funds
    category was -3.31%.

Q   How would you characterize the investment environment for international
    equities during the 12-month period ended November 30, 2016?

A   International equities faced macroeconomic headwinds during the period that
    weighed on their performance, despite some positive momentum in the second
    and third quarters of 2016. During the early months of the 12-month
    period, international stocks came under pressure due to a China-led
    slowdown in global economic growth, weaker U.S. economic data, and a
    renewed decline in oil prices that contributed to a sell-off in

    higher-risk assets. By the middle of February 2016, however, the outlook
    for international equities began to brighten as oil prices bottomed in
    hopes of an agreement by OPEC (Organization of Petroleum Exporting
    Countries) and non-OPEC countries on a production freeze, and then
    recovered. The market rally strengthened as the U.S. Federal Reserve (the
    Fed) postponed further interest-rate increases until much later in the
    calendar year, corporations across the developed markets reported
    better-than-expected earnings growth, and investors took encouragement from
    fiscal stimulus measures by the European Central Bank and the Bank of Japan.

    In late June, the surprising results of the "Brexit" referendum in the
    United Kingdom (U.K.), in which the electorate chose to leave the European
    Union, caused a steep sell-off. The disruption was very brief, however, as
    markets quickly recovered their losses before the end of the month, buoyed
    by the promise of still more accommodative monetary policies from central
    banks. As the 12-month period neared its end, the market was dealing with
    new political uncertainties, questions about further central-bank stimulus
    measures, and concerns about the health of some European banks.  However,
    evidence that both consumer and corporate confidence was improving tended
    to balance out the worries.

    From a regional perspective, developing markets and Japan delivered
    positive results during the period, but weaker performance by European
    stocks overshadowed those gains. Consequently, international stocks
    underperformed U.S. stocks during the full 12-month period. From a sector
    perspective, energy, materials, industrials, information technology, and
    financials were the top-performing sectors in the MSCI EAFE ND Index (the
    MSCI Index) during the Fund's fiscal year, while health care struggled.
    The consumer and utility sectors, too, were down slightly.

Q   Which of your investment strategies or individual portfolio holdings
    detracted from the Fund's performance relative to the benchmark MSCI Index
    during the 12-month period ended November 30, 2016?

A   The Fund's investments in U.K. companies, particularly those exposed to the
    domestic economy, took a negative toll on benchmark-relative performance
    following the Brexit vote. There remains much uncertainty over the
    long-term effects of the voters' decision, particularly for companies
    waiting to see how the U.K.'s trading relationship with the European Union
    will be affected. The British pound has plunged since the Brexit vote,
    given questions about the risk of recession in the U.K.

    During the period, some of our sector allocation decisions also detracted
    from the Fund's benchmark-relative performance. The portfolio's underweight
    exposure to the energy sector weighed on relative returns when commodities
    prices started to recover from 25-year lows in February

                  Pioneer International Equity Fund | Annual Report | 11/30/16 5


    2016. The Fund's underweight exposure to banks also detracted from
    benchmark-relative performance when financials rallied during the second
    half of the 12-month period.

    Finally, the Fund's holdings in real estate held back benchmark-relative
    results. Last August, REITs (real estate investment trusts) and other real
    estate-related stocks became a separate sector in the MSCI Index (and other
    equity market indices). Previously, REITs/real estate had been a part of
    the financials sector.

    While international real estate stocks had been performing well up to that
    point, it seems as though investors took the opportunity to sell their
    holdings in order to lock in profits, thus putting downward pressure on the
    stock prices of real estate-related investments.

    As for individual portfolio holdings, the Fund's position in the U.K.
    hotel, coffee shop, and restaurant business chain Whitbread struggled
    during the period in response to Brexit fears. Although earnings growth has
    been slower than expected, we believe Whitbread is an excellent franchise
    and continue to hold the stock in the portfolio. Hibernia REIT, an Irish
    real estate company with a concentration of commercial properties in
    Dublin, also detracted from the Fund's benchmark-relative performance. In
    recent years, the company has bought distressed properties from banks and
    refurbished them for lease to international companies. With management
    issuing more stock to finance expansion, we believe that some income-
    oriented investors who look to REITs as an income vehicle sold their
    positions in Hibernia. We take a longer view with regard to Hibernia's
    prospects, however, and remain committed to the stock and its future growth
    potential.

    The Fund's position in Hitachi, the Japanese multinational conglomerate,
    also struggled during the period. Management has been in the process of a
    major restructuring of the company's 11 business segments in an attempt to
    improve profitability. However, the reorganization has turned out to be a
    slow process, and we thought it best to sell the Fund's position.

Q   Which of your investment strategies or individual portfolio holdings
    contributed to the Fund's benchmark-relative performance during the 12-month
    period ended November 30, 2016?

A   Stock selection results in the industrials sector, and in some of the Fund's
    positions in electronics companies benefited benchmark-relative returns
    during the period. While many industrial companies sold off in the wake of
    China's economic slowdown, some have successfully developed markets outside
    of China, and their stocks began to recover in 2016. As such,

6 Pioneer International Equity Fund | Annual Report | 11/30/16


    Daikin Industries was the Fund's top-performing position during the period.
    The company is a global manufacturer of quiet and compact residential and
    commercial-grade air conditioners, and it has benefited from increased
    demand from businesses as well as from a rising middle class in the Pacific
    Rim.

    Within electronics, shares of Mitsubishi Electric, a global manufacturer of
    electric and electronic equipment, including air-conditioning systems,
    industrial automation, and communications, aided the Fund's benchmark-
    relative performance during the period. We bought the stock when it was, in
    our opinion, deeply undervalued. Even with rally over the 12-month period,
    we believe Mitsubishi's stock price remains attractive and that the company
    has more upside earning potential.

    A position in Taiwan Semiconductor, the world's largest dedicated
    independent semiconductor foundry, was the third best-performing stock in
    the Fund's portfolio over the fiscal year ended November 30, 2016, and
    contributed positively to benchmark-relative returns. Taiwan Semiconductor
    has a customer base of companies that are leaders in their respective
    industries, including Apple. With its factories running at full capacity,
    Taiwan Semiconductor's earnings continued to be robust, and that has
    resulted in strong performance.

Q   Were there any noteworthy shifts in the Fund's strategy or allocations
    during the 12-month period ended November 30, 2016?

A   We moved the Fund's geographic and sector allocations so that they were more
    in line with the MSCI Index by the close of the reporting period, though the
    shifts came as a byproduct of our investment decisions. For example, as the
    period progressed we uncovered European stocks that we believed had
    attractive prices and that offered better growth potential than stocks in
    Asia.

    After a considerable rally in Japanese stocks, including the Fund's
    investments in Alps Electric, Sundrug, and Bridgestone, we scaled back the
    portfolio's exposures to those and other Japanese holdings in order to lock
    in profits. We subsequently reallocated the proceeds of those sales to
    European financial firms, such as ING Group. In recent years, European
    banks have strengthened their balance sheets and reduced the risk profile
    of their assets. Accordingly, we believe European banks have better
    capitalization and operate in a more efficient manner, which should
    position them to grow earnings after years of building up capital.

    The end result of those and other investment decisions was that the Fund's
    underweight in European stocks and its overweight in Asian stocks moved
    more in line with benchmark's weightings by the end of the period. In a

                  Pioneer International Equity Fund | Annual Report | 11/30/16 7


    similar fashion, the portfolio's sector allocations shifted closer to the
    benchmark's, most notably due to increased exposure to the financials
    sector.

Q   Did you utilize derivatives in managing the Fund during the 12-month period
    ended November 30, 2016, and did the exposure have an effect on performance?

A   During the second half of the reporting period, we employed currency-related
    derivative securities to help minimize the negative effects of a rising
    Japanese yen on the valuation of Japanese stocks held in the portfolio. The
    Fund's derivative positions had a positive effect on performance.

Q   What is your outlook for international stocks as we head into a new year?

A   Looking back on the recently completed 12-month period, we saw large moves
    in foreign currencies, especially the Japanese yen, while the British pound
    and the euro weakened. We also saw several long-term trends starting to
    reverse course. Interest rates began to rise in the United States, after a
    16-year period of falling or historically low rates. Inflation, too,
    appears poised to start increasing in some markets, most notably the United
    States. A push for higher wages in much of the developed world at a time
    when a large number of people currently in the workforce are heading
    towards retirement may put additional pressure on wage growth. We also
    believe that the movement to increase productivity with greater use of
    automation will create ripple effects across many industries. Lastly, the
    spillover from the Brexit/anti-European Union vote and the rise of
    nationalistic sympathies in other countries could lead to fragmentation of
    the euro zone, possibly affecting European markets and the future of a
    single euro currency.

    How these and other unforeseen events may affect global trade, company
    profitability, and the performance of international stocks going forward
    underscores the importance, in our opinion, of actively managed mutual
    funds. We will continue to closely follow these and other developments as
    we strive to identify companies with solid balance sheets and the potential
    to grow organically amid these myriad crosscurrents.

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, 2017, 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.

Please refer to the financial highlights for a more current expense ratio.

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).  "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

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.

Please refer to the financial highlights for a more current expense ratio.

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 1.09% for Class A, Class C and Class Y shares, respectively,
    multiplied by the average account value over the period, multiplied by
    183/366 (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 | 11/30/16

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. 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 (U.S. GAAP) that require the management
of the Fund to 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 Fund is an investment company and follows investment company accounting and
reporting guidance under U.S. GAAP. 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 | 11/30/16 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.

     Securities for which independent pricing services or broker-dealers 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 investment adviser and a wholly owned
     indirect subsidiary of UniCredit S.p.A. (UniCredit), pursuant to procedures
     adopted by the 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.

32 Pioneer International Equity Fund | Annual Report | 11/30/16


     At November 30, 2016, there were no securities that were valued using fair
     value methods (other than securities valued using prices supplied by
     independent pricing services).

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 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.   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, 2016, 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, 2016, the Fund paid no such taxes.

                 Pioneer International Equity Fund | Annual Report | 11/30/16 33


     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. GAAP. 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. At November 30, 2016, the Fund
     reclassified $334,432 to increase undistributed net investment income and
     $334,432 to increase accumulated net realized loss on investments, futures
     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, 2016, the Fund was permitted to carry forward indefinitely
     $5,265,835 of short-term losses and $5,730,776 of long-term losses under
     the Regulated Investment Company Modernization Act of 2010 without
     limitation. Additionally, at November 30, 2016, the Fund had a net capital
     loss carryforward of $109,242,908, which will expire in 2017 if not
     utilized.

     The Fund has elected to defer $423,432 of Post-October losses recognized
     between December 1, 2015 and November 30, 2016 to its fiscal year ending
     November 30, 2017.

     The tax character of distributions paid during the fiscal years ended
     November 30, 2016 and November 30, 2015 were as follows:



     ---------------------------------------------------------------------------
                                                           2016             2015
     ---------------------------------------------------------------------------
                                                               
     Distribution paid from:
     Ordinary income                                 $3,049,827      $11,143,703
     ---------------------------------------------------------------------------
        Total                                        $3,049,827      $11,143,703
     ===========================================================================


     The following shows the components of distributable earnings on a federal
     income tax basis at November 30, 2016:



     --------------------------------------------------------------------------
                                                                           2016
     --------------------------------------------------------------------------
                                                               
     Distributable earnings:
     Undistributed ordinary income                                $   1,559,252
     Capital loss carryforward                                     (120,239,519)
     Current year late year loss deferral                              (423,432)
     Net unrealized appreciation                                      2,447,337
     --------------------------------------------------------------------------
        Total                                                     $(116,656,362)
     ==========================================================================


     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.

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, earned $10,070 in
     underwriting commissions on the sale of Class A shares during the year
     ended November 30, 2016.

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 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.

G.   Risks

     The value of securities held by the fund may go up or down, sometimes
     rapidly or unpredictably, due to general market conditions, such as real or
     perceived adverse economic, political or regulatory conditions, inflation,
     changes in interest rates, lack of liquidity in the bond markets or adverse
     investor sentiment. In the past several years, financial markets have
     experienced increased volatility, depressed valuations, decreased liquidity
     and heightened uncertainty. These conditions may continue, recur, worsen or
     spread.

     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

                 Pioneer International Equity Fund | Annual Report | 11/30/16 35


     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.   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 for the year ended November
     30, 2016 was $(1,145,156). At November 30, 2016, the Fund had no open
     futures contracts.

2. Management Agreement

PIM 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, 2016,
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, 2018. 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, 2016 are reflected on the Statement of Operations. Class Y
shares do not have an expense limitation.

36 Pioneer International Equity Fund | Annual Report | 11/30/16


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
$7,139 in management fees, administrative costs and certain other reimbursements
payable to PIM at November 30, 2016.

3. Transfer Agent

Boston Financial Data Services, Inc. serves as the transfer agent to the Fund at
negotiated rates. Transfer agent fees and payables shown on the Statement of
Operations and the Statement of Assets and Liabilities, respectively, include
sub-transfer agent expenses incurred through the Fund's omnibus relationship
contracts.

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 and outgoing phone calls. For the year
ended November 30, 2016, such out-of-pocket expenses by class of shares were as
follows:

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


4. Distribution Plan

The Fund has adopted a Distribution Plan (the 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 $1,438 in
distribution fees payable to PFD at November 30, 2016.

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

                 Pioneer International Equity Fund | Annual Report | 11/30/16 37


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, 2016, CDSCs in the amount of $2,151
were paid to PFD.

5. 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 February 9, 2016, was in the amount of $240
million. Effective February 10, 2016, the facility is in the amount of $220
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, 2016, the Fund had no
borrowings under the credit facility.

6. Additional Disclosures about Derivative Instruments and Hedging Activities

The Fund's use of derivatives may subject 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.

38 Pioneer International Equity Fund | Annual Report | 11/30/16


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, 2016 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:
--------------------------------------------------------------------------------
We have audited the accompanying statement of assets and liabilities, including
the schedule of investments, of Pioneer International Equity Fund (the "Fund")
(the sole fund constituting Pioneer Series Trust VIII), as of November 30, 2016,
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 three 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, and 2012, 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, 2016, 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, 2016, the results of its
operations for the year then ended, the changes in its net assets for each of
the two years in the period then ended, and the financial highlights for each of
the three years in the period then ended, in conformity with accounting
principles generally accepted in the United States of America.

Additional Information (unaudited)

Pioneer Investment Management, Inc. (the "Adviser"), the Fund's investment
adviser, is currently an indirect, wholly owned subsidiary of UniCredit S.p.A.
("UniCredit"). On December 12, 2016, UniCredit announced that it has entered
into a binding agreement for the sale of its Pioneer Investments business, which
includes the Adviser, to Amundi (the "Transaction"). Amundi is headquartered in
Paris, France, and, as of September 30, 2016, had more than $1.1 trillion in
assets under management worldwide. The closing of the Transaction is expected to
happen in 2017, subject to certain regulatory and antitrust approvals, and other
conditions.

Under the Investment Company Act of 1940, the closing of the Transaction will
cause the Fund's current investment advisory agreement with the Adviser to
terminate. Accordingly, the Fund's Board of Trustees will be asked to approve a
new investment advisory agreement for the Fund. 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 | 11/30/16 41


Approval of Investment Advisory Agreement

Pioneer Investment Management, Inc. (PIM) serves as the investment adviser to
Pioneer International Equity 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 2016 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 2016 and May
2016. 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 2016, 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 May 2016,
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 July and
September 2016.

At a meeting held on September 13, 2016, 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 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.

42 Pioneer International Equity Fund | Annual Report | 11/30/16


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 peer group of
funds selected on the basis of criteria determined by the Independent Trustees
for this purpose using data provided by Strategic Insight

                 Pioneer International Equity Fund | Annual Report | 11/30/16 43


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 to 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 to
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 and that the
results of the most recent such review were considered in the consideration of
the Fund's expense ratio.

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 management fee for the Fund and
considered that, under the investment

44 Pioneer International Equity Fund | Annual Report | 11/30/16


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, including the profit margins, 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.

                 Pioneer International Equity Fund | Annual Report | 11/30/16 45


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.
