President's Letter

Dear Shareowner,

When we look at the U.S. economy heading into 2014, we continue to see slow, but
steady, growth. Employment has also been rising steadily, but only modestly.
Consumer incomes, savings, wealth, and debt-servicing capacity have been solid
buttresses for the recovering housing and auto industries. Industrial activity
is growing only modestly, but current corporate profits are generally solid and
balance sheets appear able to support needed capital spending and dividend*
payouts. The scaled-back "fiscal cliff" tax increases and spending cuts have
meaningfully cut the budget deficit without driving the economy into recession.
In addition, we feel that continuing slack in labor markets and capacity
utilization offers the potential for continuing growth without bottlenecks and
rising inflation.

After observing the strengthening economic trends, the Federal Reserve (the Fed)
hinted that it might begin scaling back its "QE" quantitative easing program
later in 2013 and could terminate its bond purchases altogether sometime in
2014. In September, however, the Fed surprised many market participants by
deciding not to start scaling back QE yet, but announced later in the year that
it would, in fact, begin tapering QE. The Fed has also said that short-term
interest rates are likely to remain near zero for some time to come, given that
inflation remains subdued and unemployment remains too high.

The U.S. government's partial shutdown in October rattled the markets to a
degree, but did not immediately have a significant negative impact on the
economy or capital markets. As the year drew to a close, leaders in Washington
reached a bipartisan budget agreement that establishes top-line government
spending levels for the next two fiscal years, a move which should help to
diffuse the threat of another shutdown. That certainly was welcome news for
investors who had grown weary of the uncertainty caused by the constant,
politically motived bickering over the nation's fiscal policies.

There are certainly risks and uncertainties that continue to plague the global
economy as we head into the new year. The European economy remains weak, though
it is beginning to show signs of stabilization, and a number of countries in the
emerging markets have experienced difficulties. Still, a potential ending of the
European recession, continuing economic improvement in Japan in response to the
new government's easing policies, and a "soft landing" of 7% growth in China
could very well result in an improving global outlook in 2014.

There are also geopolitical worries abroad and the aforementioned political
fights at home, and while most of the widely recognized risks we've outlined may
already be "priced into" the market, we believe investors should continue to
expect market volatility.

The Fed's aggressive monetary policies and fears about economic growth had
helped drive long-term Treasury yields to unsustainably low levels; the return
to more normal levels has resulted in disappointing returns for bond investors
during much of 2013, but the stock market has delivered double-digit returns to
equity investors who were willing to brave the "wall of worry".

At Pioneer, we have long advocated the benefits of staying diversified and
investing for the long term. And while diversification does not assure a profit
or protect against loss in a declining market, we believe there are still
opportunities for prudent investors to earn attractive returns. Our advice, as
always, is to work closely with a trusted financial advisor to discuss your
goals and work together to develop an investment strategy that meets your
individual needs, keeping in mind that there is no single best strategy that
works for every investor.

Pioneer's investment teams have, since 1928, sought out attractive opportunities
in global equity and bond markets, using in-depth research to identify
undervalued individual securities, and using thoughtful risk management to
construct portfolios which seek to balance potential risks and reward in an
ever-changing world.

We encourage you to learn more about Pioneer and our time-tested approach to
investing by consulting with your financial advisor or visiting us online at

you for investing with Pioneer.

Sincerely,

Portfolio Management Discussion | 11/30/13

In the following interview, Mauro Ratto, Marco Mencini, and Andrea Salvatori,
portfolio managers of Pioneer Emerging Markets Fund, discuss the investment
environment and the Fund's performance during the 12-month period ended November
30, 2013. Mr. Ratto, Head of Emerging Markets and a portfolio manager at
Pioneer, Mr. Mencini, Head of Equities, Emerging Markets, and a portfolio
manager at Pioneer, and Mr. Salvatori, Head of Global Emerging Markets & Latin
American Equities and a portfolio manager at Pioneer, assumed responsibility for
the day-to-day management of the Fund on March 1, 2013, replacing Sean Taylor.

Q   Could you please review the performance of emerging markets stocks during
    the 12-month period ended November 30, 2013?

A   Stocks in the emerging markets experienced weak relative performance during
    the Fund's annual reporting period. The Fund's benchmark, the Morgan Stanley
    Capital International (MSCI) Emerging Markets ND Index(1), returned 3.66%
    for the period, well below the 26.38% return of the MSCI World ND Index,
    which tracks the performance of stocks in the developed markets.

    The primary reason for the substantial performance shortfall of emerging
    markets equities was the direction of economic growth in several emerging
    nations. While economies in the developed markets showed improvement during
    the 12-month period, growth in the emerging economies continued to slow.
    Slower growth, in turn, led to a decline in earnings rates of companies in
    the emerging markets to levels that were below longer-term trends. A
    decoupling of monetary policies of the world's central banks also played a
    role in the emerging markets' underperformance during the period. While
    central banks in the developed markets, such as the U.S. Federal Reserve
    (the Fed), continued to pursue "easy money" policies, higher inflation
    forced many central banks in the emerging markets to

    tighten policy by raising interest rates. Finally, the emergence of worries
    that the Fed would begin to "taper" the pace of its quantitative easing (QE)
    program fueled an exodus of capital from the emerging markets during the
    spring and summer. The Fed eventually opted to delay the tapering of QE
    until late in the calendar year, but the effects of last summer's
    speculation had already taken their toll on the emerging markets. Taken
    together, all of the factors led to a substantial divergence in returns
    between the developed and emerging equity markets.

Q   How did the Fund perform in that environment during the 12-month period
    ended November 30, 2013?

A   Pioneer Emerging Markets Fund's Class A shares returned 3.98% at net asset
    value during the 12-month period ended November 30, 2013, while the Fund's
    benchmark, the MSCI Emerging Markets ND Index (the MSCI Index), returned
    3.66%. During the same period, the average return of the 587 mutual funds in
    Lipper's Emerging Markets Funds category was 5.40%, and the average return
    of the 598 mutual funds in Morningstar's Diversified Emerging Markets Funds
    category was 5.33%.

Q   Which of your investment decisions aided the Fund's performance during the
    12-month period ended November 30, 2013, and which investment strategies
    detracted from the Fund's performance?

A   After the new portfolio management team took over the Fund in March 2013,
    four months into the annual reporting period, we repositioned the Fund's
    portfolio to match our investment style. In the time following the
    repositioning of the portfolio, one of the key positive factors in the
    Fund's benchmark-relative performance was our decision to overweight the
    strong consumer discretionary sector. Stock selection within the consumer
    discretionary group also contributed to the Fund's relative returns. Within
    consumer discretionary, the Fund's position in ANTA Sports Products, a
    Chinese sportswear producer that benefitted from an improving competitive
    environment and better inventory management, was a leading contributor to
    relative performance during the period. A position in Copa Holdings, a
    Panamanian airline with a competitive business model that we believed was
    being overlooked by investors, also contributed to the Fund's performance.
    Copa has delivered strong results, putting it on investors' radar screens
    and allowing the stock's market price to move closer to what we see as its
    fair value.

    Other positive contributors to the Fund's performance during the period
    included a position in Astaldi, an Italian construction and engineering firm
    that generates more than half of its revenues in Turkey and other emerging
    markets. The stock gained ground as investors became less concerned about
    the financial risk in the company's Italian business and grew to appreciate
    the value of its operations within the emerging markets. The Fund's relative

                      Pioneer Emerging Markets Fund | Annual Report | 11/30/13 5


    performance was further aided by a position in Minsheng Bank, which we
    bought when the company's shares were depressed in the early summer of 2013.
    Concerns about a scare in China's short-term funding market led to a sharp
    sell-off in the country's banking sector, and we were able to pick up shares
    of this well-run bank at a discount. The stock subsequently rebounded before
    period end.

    On the negative side, the portfolio's overweight positions in China and
    Russia detracted from the Fund's relative performance during the 12-month
    period. We are optimistic, however, about the longer-term outlook for both
    countries, and we are maintaining the Fund's above-benchmark weightings.

    In terms of individual stocks, one of the Fund's largest performance
    detractors was a position in Korean cosmetics maker Able C&C. The company
    lost market share during the period due to heavy promotion and aggressive
    pricing by its competitors, which weighed on Able's profit margins. We have
    since reduced the Fund's position. A holding of another Korean company,
    Samsung Engineering, also hurt the Fund's return due to a decline in company
    revenues and weaker-than-expected profit margins. Hon Hai Precision
    Industry, the largest technology assembler in the world as well as Apple's
    top supplier, was another Fund position that detracted from performance
    during the period. Hon Hai became caught up in the broader decline of
    Apple's stock as well as stocks of other companies within its "ecosystem."
    Still, we believe Hon Hai's scale advantages will translate into higher cash
    flows over time, and so we have maintained the Fund's position.

Q   What is your outlook for equity investing within the emerging markets?

A   We hold a cautious outlook for the asset class as we move into 2014. In
    order to make the emerging markets an attractive destination for investors,
    we believe that structural reforms are badly needed in many countries, given
    that most economies in the region suffer from excessive credit growth and an
    overhang of leverage. Emerging countries as a group have experienced a
    deteriorating macroeconomic outlook during the past five years, which, in
    our view, highlights the need for reforms. Despite the obvious sense of
    urgency in the "fragile" emerging countries, any reform efforts will have to
    wait many more months due to forthcoming elections in several nations; and,
    currently, only China and Mexico seem to be moving in the right direction in
    our opinion. Having said this, both performance expectations and company
    valuations have declined considerably throughout the region, suggesting the
    possibility of upside potential if global growth picks up and the reform
    process gathers steam.

6 Pioneer Emerging Markets Fund | Annual Report | 11/30/13


When investing the Fund's assets, we continue to seek countries with positive
trade balances, lower vulnerability to global asset flows, exposure to the
global economy, and a credible plan for structural reform. Among the countries
included in that group are China, Mexico, and the Philippines. We have tilted
the Fund's portfolio toward more cyclical (economically sensitive) sectors such
as industrials, consumer discretionary, and information technology, while
reducing exposure to the defensive sectors, like consumer staples, as stocks in
those sectors appear likely to underperform due to their elevated valuations.

From a valuation perspective, we believe the emerging markets look attractive
both on an absolute basis and relative to the developed markets. This is
particularly evident in Russia, where we maintain an overweight portfolio
position. We are mindful of the fact that some Russian stocks are cheap for a
good reason. However, we do see some growth catalysts that we feel could improve
the situation in the Russian market, including a strong new central bank
governor, government policies aimed at improving corporate governance at
state-owned companies, and financial reforms designed to open up the market to
new investors.

While growth has slowed in China from previous highs, we remain optimistic that
the Chinese government has both the ability and political will to implement
certain structural reforms and to slowly guide the nation towards a more
sustainable growth rate as well as a consumer-driven economy. We believe the
Fund, with its emphasis on consumer discretionary stocks in China, is positioned
to benefit if that nation's trajectory towards a consumer-driven economy
materializes.

The Fund also holds a weighting in the frontier economies (also known as
"pre-emerging" economies). Frontier economies are expected to be the new engines
of growth in the emerging markets, and we have continued to build the Fund's
positions in countries such as Saudi Arabia, Qatar, and Dubai. We also have
continued our play on the Asian urbanization theme within the portfolio, and
have added a basket of small- and mid-cap holdings in the region. Lastly, the
Fund has allocations to certain developed market-listed stocks, such as
Astaldi's, whose performance is driven largely by the companies' exposures to
emerging markets penetration and growth.

In an environment characterized by both risk and opportunity, we continue to
emphasize individual research to identify companies that we believe have the
optimal combination of growth potential and attractive valuation. We believe
this steady approach will enable the Fund to navigate the inevitable shifts in
short-term market conditions and to deliver solid performance over the longer
term.

Please refer to the Schedule of Investments on pages 18-27 for a full listing of
Fund securities.

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

The portfolio may invest a substantial amount of its assets in issuers located
within a specific region, and is, therefore, more susceptible to adverse
developments affecting those regions.

At times, the Fund's investments may represent industries or industry sectors
that are interrelated or have common risks, making it more susceptible to any
economic, political, or regulatory developments or other risks affecting those
industries and sectors.

These risks may increase share price volatility.

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

sales charges, fees or expenses. It is not possible to invest directly in an
index.

The index defined here pertains to the "Value of $10,000 Investment" and "Value
of $5 Million Investment" charts on pages 11-15.

Call 1-800-225-6292 or visit us.pioneerinvestments.com for the most recent
month-end performance results. Current performance may be lower or higher than
the performance data quoted.

The performance data quoted represents past performance, which is no guarantee
of future results. Investment return and principal value will fluctuate, and
shares, when redeemed, may be worth more or less than their original cost.

NAV results represent the percent change in net asset value per share. Returns
would have been lower had sales charges been reflected. POP returns reflect
deduction of maximum 5.75% sales charge. All results are historical and assume
the reinvestment of dividends and capital gains. Other share classes are
available for which performance and expenses will differ.

Performance results reflect any applicable expense waivers in effect during the
periods shown. Without such waivers Fund performance would be lower. Waivers may
not be in effect for all funds. Certain fee waivers are contractual through a
specified period. Otherwise, fee waivers can be rescinded at any time. See the
prospectus and financial statements for more information.

The net expense ratio reflects contractual expense limitations currently in
effect through April 1, 2015, for Class A shares. There can be no assurance that
Pioneer will extend the expense limitations beyond such time. Please see the
prospectus and financial statements for more information.

The performance table and graph do not reflect the deduction of fees and taxes
that a shareowner would pay on Fund distributions or the redemption of Fund
shares.

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

    2.78%, 2.13% and 1.38% for Class A, Class B, Class C, Class R and Class 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), that are charged at the time of the transaction. Therefore, the
table below is useful in comparing ongoing costs only and will not help you
determine the relative total costs of owning different funds. In addition, if
these transaction costs were included, your costs would have been higher.

1. Organization and Significant Accounting Policies

Pioneer Emerging Markets Fund (the Fund) is a Delaware statutory trust. The Fund
is registered under the Investment Company Act of 1940 as a diversified,
open-end management investment company. The investment objective of the Fund is
long-term growth of capital.

The Fund offers five classes of shares designated as Class A, Class B, Class C,
Class R, and Class Y shares. Effective as of the close of business on December
31, 2009, Class B shares are no longer offered to new or existing shareholders,
except that dividends and/or capital gain distributions may continue to be
reinvested in Class B shares, and shareholders may exchange their Class B shares
for Class B shares of other Pioneer funds, as permitted by existing exchange
privileges. Each class of shares represents an interest in the same portfolio of
investments of the Fund and has identical rights (based on relative net asset
values) to assets and liquidation proceeds. Share classes can bear different
rates of class-specific fees and expenses such as transfer agent and
distribution fees. Differences in class-specific fees and expenses will result
in differences in net investment income and, therefore, the payment of different
dividends from net investment income earned by each class. The Amended and
Restated Declaration of Trust of the Fund gives the Board the flexibility to
specify either per-share voting or dollar-weighted voting when submitting
matters for shareholder approval. Under per-share voting, each share of a class
of the Fund is entitled to one vote. Under dollar-weighted voting, a
shareholder's voting power is determined not by the number of shares owned, but
by the dollar value of the shares on the record date. Each share class has
exclusive voting rights with respect to matters affecting only that class,
including with respect to the distribution plan for that class. There is no
distribution plan for Class Y shares. Class B shares convert to Class A shares
approximately eight years after the date of purchase.

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

                     Pioneer Emerging Markets Fund | Annual Report | 11/30/13 37


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

A.  Security Valuation

    Security transactions are recorded as of trade date. The net asset value of
    the Fund is computed once daily, on each day the New York Stock Exchange
    (NYSE) is open, as of the close of regular trading on the NYSE. In computing
    the net asset value, securities that have traded on an exchange are valued
    using the last sale price on the principal exchange where they are traded.
    Securities that have not traded on the date of valuation, or securities for
    which sale prices are not available, generally are valued using the mean
    between the last bid and asked prices. Short-term fixed income securities
    with remaining maturities of sixty days or less generally are valued at
    amortized cost. Shares of money market mutual funds are valued at such
    funds' net asset value.

    The Fund invests primarily in securities of non-U.S. issuers. The principal
    exchanges and markets for such securities have closing times prior to the
    close of the NYSE. However, the value of these securities may be influenced
    by changes in global markets occurring after the closing times of the local
    exchanges and markets up to the time the Fund determines its net asset
    value. Consequently, the Board of Trustees of the Fund has determined that
    daily adjustments to the valuation of securities of non-U.S. issuers by
    utilizing an independent pricing service that supplies an appropriate fair
    value factor is appropriate for the Fund.

    Securities for which 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 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. 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. PIM's fair valuation team is responsible for
    monitoring developments that

38 Pioneer Emerging Markets Fund | Annual Report | 11/30/13


    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.

    At November 30, 2013, there were three securities valued using fair value
    methods (in addition to securities that were valued using prices supplied by
    independent pricing services) representing 0.15% of net assets.

    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.

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

B.  Foreign Currency Translation

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

    Net realized gains and losses on foreign currency transactions, if any,
    represent, among other things, the net realized gains and losses on foreign
    currency contracts, disposition of foreign currencies and the difference
    between the amount of income accrued and the U.S. dollars actually received.
    Further, the effects of changes in foreign currency exchange rates on
    investments are not segregated in the Statement of Operations from the
    effects of changes in the market prices of those securities but are included
    with the net realized and unrealized gain or loss on investments.

C.  Forward Foreign Currency Contracts

    The Fund may enter into forward foreign currency contracts (contracts) for
    the purchase or sale of a specific foreign currency at a fixed price on a
    future date. All contracts are marked to market daily at the applicable
    exchange rates, and any resulting unrealized appreciation or depreciation is
    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).

                     Pioneer Emerging Markets Fund | Annual Report | 11/30/13 39


D.  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.
    The use of futures contracts involves, to varying degrees, elements of
    market, interest rate, currency exchange rate and counterparty risks, which
    may exceed the amounts recognized by the Fund. Changes in value of the
    contracts may not directly correlate to the changes in value of the
    underlying securities. The value of contracts open for the year during the
    one month ended November 30, 2013 was $8,067,375.

    At November 30, 2013, open futures contracts were as follows:

    Type                    Long/(Short)   Month        Value       Appreciation
    ----------------------------------------------------------------------------

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


E.  Purchased Options

    The Fund may purchase call and put option in order to attempt to hedge
    against changes in the value of portfolio securities or to seek to increase
    total return. Purchased call and put options entitle the Fund to buy and
    sell a specified number of shares or units of a particular security,
    currency or index at a specified price at a specific date or within a
    specific period of time. Upon the purchase of a call or put option, the
    premium paid by the Fund is included in the Statement of Assets and
    Liabilities as an investment. All premiums are marked-to-market daily, and
    any unrealized gains or losses are recorded in the Fund's financial
    statements. As the purchaser of an index option, the Fund has the right to
    receive a cash payment equal to any depreciation in the value of the index
    below the strike price of the option (in the case of a put) or equal to any
    appreciation in the value of the index over the strike price of the option
    (in the case of a call) as of the valuation date of the option. Premiums
    paid for purchased calls and put options which have

40 Pioneer Emerging Markets Fund | Annual Report | 11/30/13


    expired are treated as realized losses on investments in the Statement of
    Operations. Upon the exercise or closing of a purchased put option, the
    premium is offset against the proceeds on the sale of the underlying
    security or financial instrument in order to determine the realized gain or
    loss on investments. Upon the exercise or closing of a purchased call
    option, the premium is added to the cost of the security or financial
    instrument. The risk associated with purchasing options is limited to the
    premium originally paid. The value of contracts open for the year during the
    one month ended November 30, 2013 was $24,118. Purchased options contracts
    outstanding at year end are listed at the end of the Fund's schedule of
    investments.

F.  Federal Income Taxes

    It is the Fund's policy to comply with the requirements of the Internal
    Revenue Code applicable to regulated investment companies and to distribute
    all of its taxable income and net realized capital gains, if any, to its
    shareowners. Therefore, no provision for federal income taxes is required.
    As of November 30, 2013, the Fund did not accrue any interest and 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 are subject to examination by
    Federal and State tax authorities.

    In addition to the requirements of the Internal Revenue Code, the Fund may
    also be required to pay local taxes on the recognition of capital gains
    and/or the repatriation of foreign currencies in certain countries. During
    the year ended November 30, 2013, the Fund paid no such taxes.

    In determining the daily net asset value, the Fund estimates the reserve for
    such taxes, if any, associated with investments in certain countries. The
    estimated reserve for the capital gains is based on the net unrealized
    appreciation on certain portfolio securities, the holding period of such
    securities and the related tax rates, tax loss carryforward (if applicable)
    and other such factors. As of November 30, 2013, the Fund had no reserve
    related to capital gains.

    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

                     Pioneer Emerging Markets Fund | Annual Report | 11/30/13 41


    character, but are not adjusted for temporary differences. At November 30,
    2013 the Fund reclassified $264,748 to decrease undistributed net investment
    income and $264,748 to decrease accumulated net realized loss on investments
    to reflect permanent book/tax differences. These adjustments have no impact
    on net assets or the results of operations.

    At November 30, 2013, the Fund was permitted to carryforward indefinitely
    $1,598,451 of short-term losses under the Regulated Investment Company
    Modernization Act of 2010 without limitation.

    During the year ended November 30, 2013, capital loss carryforward of
    $9,832,951 was utilized to offset net realized gains by the Fund.

    The tax character of distributions paid during the year ended November 30,
    2013 and November 30, 2012 was as follows:



    ----------------------------------------------------------------------------
                                                      2013                 2012
    ----------------------------------------------------------------------------
                                                               
    Distribution paid from:
    Ordinary income                             $1,427,094           $        --
    Long-term capital gain                              --             1,366,437
    ----------------------------------------------------------------------------
         Total                                  $1,427,094           $ 1,366,437
    ============================================================================


    The following shows the components of distributable earnings on a federal
    income tax basis at November 30, 2013:



    ----------------------------------------------------------------------------
                                                                          2013
    ----------------------------------------------------------------------------
                                                                
    Distributable earnings:
    Undistributed ordinary income                                  $ 1,131,971
    Capital loss carryforward                                       (1,598,451)
    Net unrealized appreciation                                     18,348,518
    ----------------------------------------------------------------------------
         Total                                                     $17,882,038
    ============================================================================


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

G.  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 $17,369 in underwriting commissions on the sale of Class A shares
    during the year ended November 30, 2013.

H.  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.

42 Pioneer Emerging Markets Fund | Annual Report | 11/30/13


    Distribution fees are calculated based on the average daily net asset value
    attributable to Class A, Class B, Class C and Class R shares of the Fund,
    respectively (see Note 4). Class Y shares do not pay distribution fees. All
    expenses and fees paid to the transfer agent, Pioneer Investment Management
    Shareholder Services, Inc. (PIMSS), for its services are allocated among the
    classes of shares based on the number of accounts in each class and the
    ratable allocation of related out-of-pocket expenses (see Note 3).

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

I.  Risks

    The Fund's investments in emerging markets or countries with limited or
    developing markets may subject the Fund to a greater degree of risk than
    investments in a developed market. Risks associated with these developing
    markets include political, social and economic factors and may affect the
    price of the Fund's investments and income generated by these investments,
    as well as the Fund's ability to repatriate such amounts. 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.

J.  Repurchase Agreements

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

2. Management Agreement

PIM, a wholly owned indirect subsidiary of UniCredit, manages the Fund's
portfolio. Prior to December 1, 2013, management fees were calculated daily at
an annual rate equal to 1.15% of the Fund's average daily net assets up to $1
billion and 1.10% on assets over $1 billion. For the year ended November 30,
2013, the effective management fee (excluding waivers and/or assumption of
expenses) was 1.15% of the Fund's average daily net assets.

                     Pioneer Emerging Markets Fund | Annual Report | 11/30/13 43


Effective December 1, 2013, management fees are calculated daily at an annual
rate equal to 1.10% of the Fund's average daily net assets up to $1 billion and
1.05% on assets over $1 billion.

PIM has contractually agreed to limit ordinary operating expenses to the extent
required to reduce Fund expenses to 1.95%, 2.85%, 2.85% and 2.20% of the average
daily net assets attributable to Class A, Class B, Class C and Class R shares,
respectively. Fees waived and expenses reimbursed during the year ended November
30, 2013 are reflected on the Statement of Operations. Class Y shares do not
have an expense limitation. These expense limitations are in effect through
April 1, 2015. There can be no assurance that PIM will extend the expense
limitation agreement for a class of shares beyond the date referred to above.

In addition, under the management and administration agreements, certain other
services and costs, including accounting, regulatory reporting and insurance
premiums, are paid by the Fund as administrative reimbursements. Included in
"Due to affiliates" reflected on the Statement of Assets and Liabilities is
$36,570 in management fees, administrative costs and certain other
reimbursements payable to PIM at November 30, 2013.

3. Transfer Agent

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

In addition, the Fund reimburses PIMSS for out-of-pocket expenses incurred by
PIMSS related to shareholder communications activities such as proxy and
statement mailings, outgoing phone calls and omnibus relationship contracts. For
the year ended November 30, 2013, such out-of-pocket expenses by class of shares
were as follows:

Class C                                                                   63,124
Class R                                                                  106,340
Class Y                                                                   17,844
--------------------------------------------------------------------------------
  Total                                                                 $417,163
--------------------------------------------------------------------------------


Included in "Due to affiliates" reflected on the Statement of Assets and
Liabilities is $109,578 in transfer agent fees and out-of-pocket reimbursements
payable to PIMSS at November 30, 2013.

4. Distribution and Service Plans

The Fund has adopted a Distribution Plan pursuant to Rule 12b-1 of the
Investment Company Act of 1940 with respect to its Class A, Class B, Class C and
Class R shares. Pursuant to the Plan, the Fund pays PFD 0.25% of the average
daily net assets attributable to Class A shares as compensation for personal
services and/or account maintenance services or distribution services with
regard to Class A shares. Pursuant to the Plan, the Fund also pays PFD 1.00% of
the average daily net assets attributable to Class B and Class C shares. The fee
for Class B and Class C shares consists of a 0.25% service fee and a 0.75%
distribution fee paid as compensation for personal services and/or account
maintenance services or distribution services with regard to Class B and Class C
shares. Pursuant to the Plan, the Fund further pays PFD 0.50% of the average
daily net assets attributable to Class R shares for distribution services.
Included in "Due to affiliates" reflected on the Statement of Assets and
Liabilities is $8,656 in distribution fees payable to PFD at November 30, 2013.

The Fund also has adopted a separate service plan for Class R shares (Service
Plan). The Service Plan authorizes the Fund to pay securities dealers, plan
administrators or other service organizations that agree to provide certain
services to retirement plans or plan participants holding shares of the Fund a
service fee of up to 0.25% of the Fund's average daily net assets attributable
to Class R shares held by such plans.

In addition, redemptions of each class of shares (except Class R and Class Y
shares) may be subject to a contingent deferred sales charge (CDSC). A CDSC of
1.00% may be imposed on redemptions of certain net asset value purchases of
Class A shares within 12 months of purchase. Class B shares that are redeemed
within five years of purchase are subject to a CDSC at declining rates beginning
at 4.00%, based on the lower of cost or market value of shares being redeemed.
Redemptions of Class C shares within 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 R or Class
Y shares. Proceeds from the CDSCs are paid to PFD. For the year ended November
30, 2013, CDSCs in the amount of $8,998 were paid to PFD.

5. Expense Offset Arrangements

The Fund has entered into certain expense offset arrangements with PIMSS which
may result in a reduction in the Fund's total expenses, due to interest earned
on cash held by PIMSS. For the year ended November 30, 2013, the Fund's expenses
were not reduced under such arrangements.

6. Forward Foreign Currency Contracts

At November 30, 2013, 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, 2013 was $5,958,620.
Open forward foreign currency contracts at November 30, 2013 were as follows:

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


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 is in the amount of $215 million. Under such facility,
depending on the type of loan, interest on borrowings is payable at the London
Interbank Offered Rate (LIBOR) plus 0.90% 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 Euro
dollar rate on the borrowing date. The Funds pay an annual commitment fee to
participate in the 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, 2013, the Fund had no borrowings
under the credit facility.

Report of Independent Registered Public Accounting Firm

To the Board of Trustees and the Shareowners of
Pioneer Emerging Markets Fund:
--------------------------------------------------------------------------------
We have audited the accompanying statement of assets and liabilities of Pioneer
Emerging Markets Fund (the "Fund"), including the schedule of investments, as of
November 30, 2013, 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 five 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.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. We were
not engaged to perform an audit of the Fund's internal control over financial
reporting. Our audits included consideration of internal control over financial
reporting as a basis for designing audit procedures that are appropriate in the
circumstances, but not for the purpose of expressing an opinion on the
effectiveness of the Fund's internal control over financial reporting.
Accordingly, we express no such opinion. An audit also includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements and financial highlights, assessing the accounting principles used
and significant estimates made by management, and evaluating the overall
financial statement presentation. Our procedures included confirmation of
securities owned as of November 30, 2013, by correspondence with the custodian
and brokers or by other appropriate auditing procedures where replies from
brokers were not received. We believe that our audits provide a reasonable basis
for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
Pioneer Emerging Markets Fund at November 30, 2013, 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 five years in the period then ended, in conformity with U.S. generally
accepted accounting principles.

Approval of Investment Advisory Agreement

Pioneer Investment Management, Inc. (PIM) serves as the investment adviser to
Pioneer Emerging Markets Fund (the Fund) pursuant to an investment advisory
agreement between PIM and the Fund. In order for PIM to remain the investment
adviser of the Fund, the Trustees of the Fund must determine annually whether to
renew the investment advisory agreement for the Fund.

The contract review process began in March 2013 as the Trustees of the Fund
agreed on, among other things, an overall approach and timeline for the process.
In July 2013, the Trustees approved the format of the contract review materials
and submitted their formal request to PIM to furnish information necessary to
evaluate the terms of the investment advisory agreement. The contract review
materials were provided to the Trustees in July 2013 and September 2013. After
reviewing and discussing the materials, the Trustees submitted a request for
additional information to PIM, and materials were provided in response to this
request. Meetings of the Independent Trustees of the Fund were held in July,
September, and November, 2013 to review and discuss the contract review
materials. In addition, the Trustees took into account the information related
to the Fund provided to the Trustees at each regularly scheduled meeting.

At a meeting held on November 12, 2013, based on their evaluation of the
information provided by PIM and third parties, the Trustees of the Fund,
including the Independent Trustees voting separately, unanimously approved the
renewal of the investment advisory agreement for another year. In considering
the renewal of the investment advisory agreement, the Trustees considered
various factors that they determined were relevant, including the factors
described below. In all quintile rankings referred to throughout this
disclosure, first quintile is most favorable to the Fund's shareowners. Thus,
highest relative performance would be first quintile and lowest relative
expenses would also be first quintile. The Trustees did not identify any single
factor as the controlling factor in determining to approve the renewal of the
agreement.

Nature, Extent and Quality of Services

The Trustees considered the nature, extent and quality of the services that had
been provided by PIM to the Fund, taking into account the investment objective
and strategy of the Fund. The Trustees reviewed the terms of the investment
advisory agreement. The Trustees also reviewed PIM's investment approach for the
Fund 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

                     Pioneer Emerging Markets Fund | Annual Report | 11/30/13 49


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

The Trustees review the Fund's performance on a regular basis, based on analysis
and data prepared by PIM for this purpose and discuss performance issues with
PIM on an ongoing basis. For purposes of their contract renewal deliberations,
the Trustees considered the performance results of the Fund over various time
periods. They reviewed information comparing the Fund's performance with the
performance of its peer group of funds as classified by Morningstar, Inc.
(Morningstar), an independent provider of investment company data, and with the
performance of the Fund's benchmark index. The Trustees considered that the
Fund's annualized total return was in the fifth quintile of its Morningstar
category for the one, three, five and ten year periods ended June 30, 2013. The
Trustees noted the discussions held throughout the year regarding the Fund's
performance and confirmed that those discussions were factored into the
Trustees' deliberations concerning the renewal of the advisory agreement. The
Trustees considered reasons for the underperformance of the Fund relative to its
peer group and the steps recently taken in an effort to improve the performance
of the Fund. The Trustees agreed that they would continue to closely monitor the
Fund's performance.

Management Fee and Expenses

The Trustees considered information showing the fees and expenses of the Fund in
comparison to the management fees and expense ratios of its peer group of funds
as classified by Morningstar and also to the expense ratios of a peer group of
funds selected on the basis of criteria determined by the Independent Trustees
for this purpose using data provided by Strategic Insight Mutual Fund Research
and Consulting, LLC (Strategic Insight), an independent third party.

50 Pioneer Emerging Markets Fund | Annual Report | 11/30/13


The Trustees considered that the Fund's management fee for the twelve months
ended June 30, 2013 was in the fourth 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 noted that the Fund's
management fee was approximately six basis points higher than the median
management fee of its Morningstar peer group. The Trustees also considered that,
effective December 1, 2013, the Fund's management fee would be reduced by five
basis points.

The Trustees considered that the Fund's expense ratio for the twelve months
ended June 30, 2013 was in the fifth quintile relative to both its Morningstar
peer group and its Strategic Insight peer group, in each case for the comparable
period. 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 noted that
they separately review the Fund's transfer agency, sub-transfer agency and
intermediary arrangements.

The Trustees reviewed management fees charged by PIM and PIM's affiliate,
Pioneer Institutional Asset Management, Inc. (together with PIM, "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 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.

                     Pioneer Emerging Markets Fund | Annual Report | 11/30/13 51


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, rarely identifiable
on a fund-by-fund basis, and that, among other factors that may be relevant, are
the following: fee levels, expense subsidization, investment by PIM in research
and analytical capabilities and PIM's commitment and 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 particularly, for example during the recent difficult periods for
financial markets, as the level of services was maintained notwithstanding a
significant decline in PIM's fee revenues from the Fund. Accordingly, the
Trustees concluded that economies of scale, if any, were being appropriately
shared with the Fund.

Other Benefits

The Trustees considered the other benefits to PIM from its relationship with the
Fund. The Trustees considered the character and amount of fees paid by the Fund,
other than under the investment advisory agreement, for services provided by PIM
and its affiliates. The Trustees further considered the revenues and
profitability of PIM's businesses other than the fund business. The Trustees
considered the intangible benefits to PIM by virtue of its relationship with the
Fund and the other Pioneer funds. The Trustees concluded that the receipt of
these benefits was reasonable in the context of the overall relationship between
PIM and the Fund.

52 Pioneer Emerging Markets Fund | Annual Report | 11/30/13


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.

                 not performed by the Audit
                 firm, the scope of the Audit

                 increase.  The Services are

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

  services by service category, including fees, provided by the Audit firm as
  set forth in the above policy.
