President's Letter

Dear Shareowner,

The U.S. stock market rallied sharply through the third quarter of 2012 amid a
sluggish, but nonetheless growing, U.S. economy. We have been cautiously
optimistic about the U.S. from the start of the year, and the economic data
continue to be encouraging. The housing and auto sectors are benefitting from
record-low interest rates. The climate for consumer and business credit has
improved, and inflation appears to be subdued. While corporate profits slowed in
the third quarter, many U.S. companies continue to have strong balance sheets
and to pay attractive dividends* compared to fixed-income securities.

All of these factors contributed to gains for investors who owned riskier
assets, including equities and higher-yielding corporate bonds. Year to date
through the end of the third quarter, the Standard & Poor's 500 Index returned
16.35%. In fixed income, the Bank of America Merrill Lynch High Yield Master II
Index was up by 12.02% during the same period, while the Barclays Capital
Aggregate Bond Index gained 3.99%. Treasury bonds, by contrast, generated a
comparatively sluggish return of 1.70%, as measured by the Barclays Capital
Intermediate Treasuries Index.

Despite this generally positive picture during the first three quarters of 2012,
investors face powerful macroeconomic challenges in the months ahead. These
include the threat of a so-called "fiscal cliff" in the U.S. budget process
after the November elections, the European sovereign-debt crisis, and slowing
growth in both Europe and China. Investors can continue to count on market
volatility tied to these factors, although we remain optimistic that the
underlying economic trends are moving in the right direction.

At Pioneer, we have long advocated the benefits of staying diversified** and
investing for the long term. And while diversification alone does not assure a
profit or protect against loss in a declining market, we believe in actively
seeking out opportunities in undervalued securities and sectors around the
globe. 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. There is no single best strategy that
works for every investor.

*   Dividends are not guaranteed.
**  Diversification does not assure a profit or protect against loss in a
    declining market.

Portfolio Management Discussion | 11/30/12

In the following interview, Sean Taylor, head of the global emerging markets
equity team and senior vice president at Pioneer, discusses the investment
environment for emerging market equities and the performance of Pioneer Emerging
Markets Fund during the 12 months ended November 30, 2012. Mr. Taylor assumed
responsibility for the daily management of the Fund on December 15, 2011.

Q   How would you describe the investment environment for emerging market stocks
    during the 12 months ended November 30, 2012?

A   Equities in the emerging markets delivered a healthy, double-digit gain
    during the 12 months ended November 30, 2012, as measured by the Fund's
    benchmark, the Morgan Stanley Capital International (MSCI) Emerging Markets
    Index1, which returned 11.73% during the period. The asset class gained
    ground during the 12-month period as the aggressive monetary stimulus of the
    world's major central banks led to a substantial improvement in investor
    sentiment. In addition, the emerging markets continued to feature a wealth
    of companies generating rapid earnings growth at a time of very sluggish
    performance for the overall global economy.

    While strong on an absolute basis, the return of the emerging markets during
    the 12-month period lagged that of the world's developed markets, as
    measured by the MSCI World Index, which returned 14.31%, and U.S. large-cap
    stocks, as measured by the Standard & Poor's 500 Index, which returned
    16.11%. The primary cause of the emerging markets' underperformance during
    the 12-month period was slowing growth across the region in general, and in
    China in particular. Although China's gross domestic product (GDP) growth
    has remained high (at 7% to 8% per year), current GDP levels represent a
    substantial decline from the 9% to 14% GDP growth the country's economy
    experienced from 2003 to 2010. Slower growth in China has had an effect on
    emerging market stocks worldwide,

    since the resulting reduction in demand for raw materials in the country has
    weighed on commodity-related companies that are heavily represented in
    markets such as Brazil, Chile, South Africa, and many others.

Q   How did the Fund perform during the 12 months ended November 30, 2012?

A   Pioneer Emerging Markets Fund's Class A shares returned 1.06% during the 12
    months ended November 30, 2012, while the Fund's benchmark, the MSCI
    Emerging Markets Index (the MSCI Index), returned 11.73%. During the same
    period, the average return of the 521 mutual funds in Lipper's Emerging
    Markets Funds category was 8.34%.

Q   What were the main reasons for the Fund's underperformance of the MSCI Index
    during the 12 months ended November 30, 2012?

A   While emerging market equities performed well during the 12-month period,
    the Fund did not participate in the rally.

    A key factor in the Fund's underperformance of the broader market during the
    period was our use of valuation as one of the most important investment
    criteria for the portfolio, during a time when investors demonstrated a
    heavy bias in favor of growth stocks. During the period, the gap between the
    two styles was so large, in fact, that the premium between growth stocks and
    value stocks moved to its widest level in several years. We believe,
    however, that the wide gap between growth and value presents an opportunity
    for a potential mean reversion (return to average price levels) among the
    many value stocks owned by the Fund.

    From an attribution standpoint, the primary cause of the Fund's shortfall
    relative to the MSCI Index during the period was stock selection,
    particularly among the portfolio's investments in Korea, Taiwan, and China.
    In Korea, the Fund's relative performance was hurt by positions in three
    industrial stocks: GS Engineering & Construction, Doosan Heavy Industries &
    Construction, and Hyundai Heavy Industries. The companies saw slowing
    business trends due to the weak global economy in general, and in China and
    Japan in particular. In Taiwan, the Fund's stock picks lagged the MSCI Index
    in the information technology/telecom services areas, where notable
    detractors in the portfolio were E Ink, Catcher Technology, and Chunghwa
    Telecom. The Fund's largest detractor holding in China was Baidu, operator
    of the country's largest Internet search engine. Although the company
    continues to report stellar growth, it was pressured by slowing economic
    growth in the country as well as the general weakness of Chinese stocks
    during the 12-month period.

                      Pioneer Emerging Markets Fund | Annual Report | 11/30/12 5


    Outside of holdings in the three Asian markets previously discussed, the
    Fund's most significant detractor holdings during the period were IAMGOLD, a
    Canada-based gold miner whose operations were interrupted by labor disputes
    in South Africa, and the Brazilian energy giant Petrobras, which saw its
    profits come under pressure due to government price controls.

    Sector allocation decisions also hurt the Fund's performance relative to the
    MSCI Index during the period. Specifically, benchmark-relative returns were
    hurt by portfolio underweights (below-benchmark weightings) in the
    financials and telecom services sectors, and overweights to information
    technology and consumer staples.

Q   Which investment decisions benefited the Fund's performance the most during
    the 12 months ended November 30, 2012?

A   The Fund added value relative to the benchmark through an underweight
    position in the underperforming materials sector, as well as stock selection
    results in the consumer staples and consumer discretionary sectors. From a
    geographical standpoint, the Fund registered its strongest performance in
    South Africa and Mexico. The Fund's holdings that contributed the most to
    performance during the period were the Latin American beverage companies
    Companhia de Bebidas das Americas ("Ambev") and Fomento Economico Mexicano,
    the Russian energy giant Gazprom, and the South African retail distributor
    Mr Price. The Fund's position in Taiwan Semiconductor also performed well
    during the period. The company is one of the largest suppliers to Apple and,
    therefore, was a beneficiary of the iPhone 5 launch.

Q   From a country or regional perspective, how was the Fund positioned as of
    November 30, 2012, and what are your views on those regions?

A   In Asia, the Fund was overweight in China and Korea as of November 30, 2012.
    Developments in China have remained equity friendly, with inflation running
    at 2% and earnings growth improving. In addition, the arrival of a new
    political leadership team suggests that policy priorities could change for
    the better, and while GDP growth may stabilize at lower levels than those
    recorded through 2010, growth in China is still quite strong on an absolute
    basis. We believe it is possible that the Chinese government may accelerate
    infrastructure investment as part of its current policy direction, and that
    would play to our existing investment strategy for the Fund in China. In
    Korea, we have maintained the portfolio's "smartphone" theme, with holdings
    in SK Hynix and Samsung Electronics.

    We also see Russia as a source of potential opportunity. In our view,
    investors have not paid attention to Russia's strengthening fundamental
    trends, such as positive credit growth, reform of the energy sector and the
    decline of the country's balance of payments. Russia represented the fourth-
    largest geographical allocation in the Fund as of November 30, 2012.

6 Pioneer Emerging Markets Fund | Annual Report | 11/30/12


    We think investors who look closely at Russia will find a country with the
    lowest price-to-earnings (P/E) ratio among all nations represented in the
    MSCI Emerging Markets Index. One reason for the country's low P/E ratio is
    investors' persistent pessimism about the Russian government's reform
    efforts, which seems based on the belief that higher oil revenues will
    enable the government to "go slow" on implementing reforms. We think that
    presents an opportunity, given that many Russian companies have been
    demonstrating rising free cash flows. The energy giant Gazprom is the Fund's
    largest holding in the country.

    In Latin America, we remain positive on the outlook for both Mexico and
    Brazil. In the case of the former, we hold a favorable view on the economy,
    but bargains in the Mexican stock market have been hard to find. In Brazil,
    we would like to see increased political clarity, particularly with regard
    to energy prices, which could be a positive for near-term equity returns.

    The Fund's largest country-specific underweight is in South Africa, a nation
    that offers a complex sociopolitical outlook and where equities have been
    trading at the high end of their historic valuation ranges. In addition,
    South Africa recently has experienced elevated levels of labor unrest and
    has been showing signs of an increasingly unfavorable political environment.
    We believe valuations near historic highs indicate that South African stocks
    aren't adequately compensating investors for the potential risks involved
    with putting their money into the country.

Q   What is your broader view on the emerging markets as we head into 2013?

A   We continue to take heart from the accommodative monetary policies of some
    of the world's major central banks. While the central banks' offerings of
    cheap credit are designed to aid economic growth in the developed world,
    emerging markets also have benefited from the policies. That can be a
    double-edged sword, however, since any threat to cheap credit conditions
    often causes investors to worry about the sustainability of such a catalyst,
    and that can lead to short-term profit taking. Therefore, we would caution
    investors that even though we hold a positive long-term view on the emerging
    markets equity asset class, market volatility may continue.

    Another potential positive for emerging market stocks is the divergence in
    available return between fixed-income securities and equities. The massive
    flow of monies into bonds in recent years has led to a sharp decline in the
    future return potential of fixed-income securities, and that makes stocks -
    which offer the combination of earnings growth and dividend yield - more
    attractive on a relative basis. We expect to see money drawn out of bonds
    and put into equities as asset allocators turn more positive in their
    outlook for global economic growth.

                      Pioneer Emerging Markets Fund | Annual Report | 11/30/12 7




    From a longer-term standpoint, we believe the underlying fundamentals of the
    emerging markets remain strong, highlighted by low interest rates, improving
    corporate governance, and sound fiscal management at the government level.
    We believe those factors, together with emerging market stocks' robust
    growth and reasonable valuations, should continue to drive favorable
    long-term returns, despite periodic short-term volatility.

Index Definition
--------------------------------------------------------------------------------
The MSCI Emerging Markets Index measures the performance of emerging market
stocks. Index returns are calculated monthly, assume reinvestment of dividends
and, unlike Fund returns, do not reflect any 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 performance table and graph do not reflect the deduction of fees and taxes
that a shareowner would pay on Fund distributions or the redemption of Fund
shares.

the performance data quoted.

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.

"If Held" results represent the percent change in net asset value per share.
Returns would have been lower had sales charges been reflected. "If Redeemed"
returns reflect the deduction of applicable contingent deferred sales charge
(CDSC). The maximum CDSC for Class B shares is 4% and declines over five years.
For more complete information, please see the prospectus.

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, 2014, for Class B 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 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.

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.

The performance shown for Class R shares for the period prior to the
commencement of operations of Class R shares on April 1, 2003, is based on the
performance of the Fund's Class A shares, reduced to reflect the higher
distribution and service fees of Class R shares. For the period beginning April
1, 2003, the actual performance of Class R shares is reflected. The performance
of Class R shares does not reflect the 1% CDSC that was in effect prior to July
1, 2004. Class R 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 net expense ratio reflects contractual expense limitations currently in
effect through April 1, 2014, for Class R 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.

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 plus the
    expense ratios of underlying funds. These combined totals were 1.97%, 2.87%,
    2.77%, 2.15% and 1.41% for Class A, Class B, Class C, Class R and Class Y
    shares, respectively. These combined ratios were multiplied by the average
    account value over the period, and then multiplied by 183/366 (to reflect
    the one-half year period) to calculate the "Expenses Paid During Period" in
    the table above.

Hypothetical Example for Comparison Purposes

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

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

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

Notes to Financial Statements | 11/30/12

1. Organization and Significant Accounting Policies

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

The Fund offers 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.

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:

36 Pioneer Emerging Markets Fund | Annual Report | 11/30/12


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 their 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 or at the
    direction or with the approval of the Valuation Committee using fair value
    methods pursuant to procedures adopted by the Board of Trustees. The
    Valuation Committee is comprised of certain members of the Board of
    Trustees. The Fund may use fair value methods if it is determined that a
    significant event has occurred after the close of the exchange or market on
    which the security trades and prior to the determination of the Fund's net
    asset value. Examples of a significant event might include political or
    economic news, corporate restructurings, natural disasters, terrorist
    activity or trading halts. Thus, the valuation of the Fund's securities may
    differ significantly from exchange prices and such differences could be
    material. Pioneer Investment Management, Inc. (PIM) 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.

                     Pioneer Emerging Markets Fund | Annual Report | 11/30/12 37


    At November 30, 2012, there were three securities valued using fair value
    methods (in addition to securities that were valued using prices supplied by
    independent pricing services) representing 0.13% of net assets. Inputs used
    when applying fair value methods to value a security may include credit
    ratings, the financial condition of the company, current market conditions
    and comparable securities.

    Dividend income is recorded on the ex-dividend date, except that certain
    dividends from foreign securities where the ex-dividend date may have passed
    are recorded as soon as the Fund becomes aware of the ex-dividend data in
    the exercise of reasonable diligence. Interest income, including interest on
    income-bearing cash accounts, is recorded on the accrual basis. Dividend and
    interest income are reported net of unrecoverable foreign taxes withheld at
    the applicable country rates.

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

B.  Foreign Currency Translation

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

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

C.  Forward Foreign Currency Contracts

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

38 Pioneer Emerging Markets Fund | Annual Report | 11/30/12


D.  Federal Income Taxes

    It is the Fund's policy to comply with the requirements of the Internal
    Revenue Code applicable to regulated investment companies and to distribute
    all of its taxable income and net realized capital gains, if any, to its
    shareowners. Therefore, no provision for federal income taxes is required.
    As of November 30, 2012, the Fund did not have any interest and penalties
    related to uncertain tax positions, which, if applicable, would be recorded
    as an income tax expense in the Statement of Operations. Tax years for the
    prior three fiscal 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, 2012, 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, 2012, 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 character, but are not adjusted for temporary differences. At
    November 30, 2012, the Fund reclassified $329,337 to decrease undistributed
    net investment income and $329,337 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, 2012, the Fund was permitted to carry forward indefinitely
    $11,431,402 of short-term losses under the Regulated Investment Company
    Modernization Act of 2010 without limitation.

    The tax character of distributions paid during the years ended November 30,
    2012 and November 30, 2011 was as follows:

    
    
    ----------------------------------------------------------------------------
                                                           2012             2011
    ----------------------------------------------------------------------------

    Long-term capital gain                            1,366,437       19,084,107
    ----------------------------------------------------------------------------
       Total                                         $1,366,437     $ 19,084,107

    The following shows the components of distributable earnings on a federal
    income tax basis at November 30, 2012:

    
    
    ----------------------------------------------------------------------------
                                                                            2012
    ----------------------------------------------------------------------------

    ----------------------------------------------------------------------------
       Total                                                        $ 8,782,212
    ============================================================================
    

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

E.  Fund Shares

    The Fund records sales and repurchases of its shares as of trade date.
    Pioneer Funds Distributor, Inc. (PFD), the principal underwriter for the
    Fund and a wholly owned indirect subsidiary of UniCredit S.p.A. (UniCredit),
    earned $21,951 in underwriting commissions on the sale of Class A shares
    during the year ended November 30, 2012.

F.  Class Allocations

    Income, common expenses and realized and unrealized gains and losses are
    calculated at the Fund level and allocated daily to each class of shares
    based on its respective percentage of adjusted net assets at the beginning
    of the day.

    Distribution fees are calculated based on the average daily net asset value
    attributable to Class A, Class B, 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).

40 Pioneer Emerging Markets Fund | Annual Report | 11/30/12


    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.

G.  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 or 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.

H.  Securities Lending

    The Fund may lend securities in its portfolio to certain broker-dealers or
    other institutional investors. When entering into a securities loan
    transaction, the Fund typically receives cash collateral from the borrower
    equal to at least the value of the securities loaned, which is invested in
    temporary investments. Credit Suisse AG, New York Branch, as the Fund's
    securities lending agent, manages the Fund's securities lending collateral.
    The income earned on the investment of collateral is shared with the
    borrower and the lending agent in payment of any rebate due to the borrower
    with respect to the securities loan, and in compensation for the lending
    agent's services to the Fund. The Fund also continues to receive payments in
    lieu of dividends or interest on the securities loaned. Gain or loss on the
    value of the loaned securities that may occur during the term of the loan
    will be for the account of the Fund. The amount of the collateral is
    required to be adjusted daily to reflect any price fluctuation in the value
    of the loaned securities. If the required market value of the collateral is
    less than the value of the loaned securities, the borrower is required to
    deliver additional collateral for the account of the Fund prior to the close
    of business on that day. The Fund has the right, under the lending
    agreement, to terminate the loan and recover the securities from the
    borrower with prior notice. The Fund is required to return the cash
    collateral to the borrower and could suffer a loss if the value of the
    collateral, as invested, has declined. As of May 8, 2012, the Fund ended its
    involvement in the securities lending program.

                     Pioneer Emerging Markets Fund | Annual Report | 11/30/12 41


I.  Repurchase Agreements

    With respect to repurchase agreements entered into by the Fund, the value of
    the underlying securities (collateral), including accrued interest, is
    required to be equal to or in excess of the repurchase price. The collateral
    for all repurchase agreements is held in safekeeping in the customer-only
    account of the Fund's custodian or a subcustodian of the Fund. 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. Management fees are calculated daily at an annual rate of 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, 2012, the effective management fee
(excluding waivers and/or assumption of expenses) was 1.15% of the Fund's
average daily net assets.

PIM has contractually agreed to limit ordinary operating expenses to the extent
required to reduce Fund expenses to 1.95%, 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, 2012 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, 2014. 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
$30,101 in management fees, administrative costs and certain other
reimbursements payable to PIM at November 30, 2012.

Effective March 5, 2012, PIM has retained Brown Brothers Harriman & Co. to
provide certain sub-administration and accounting services to the Fund.

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.

42 Pioneer Emerging Markets Fund | Annual Report | 11/30/12


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, 2012, such out-of-pocket expenses by class of shares
were as follows:



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

Class A                                                                 $351,633

Class C                                                                   54,916
Class R                                                                  150,794
Class Y                                                                   22,509
--------------------------------------------------------------------------------
   Total                                                                $591,670
================================================================================


Included in "Due to affiliates" reflected on the Statement of Assets and
Liabilities is $125,453 in transfer agent fees and out-of-pocket reimbursements
payable to PIMSS at November 30, 2012.

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 $5,496 in distribution fees payable to PFD at November 30, 2012.

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.

                     Pioneer Emerging Markets Fund | Annual Report | 11/30/12 43


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 one year of purchase are subject to a CDSC
of 1.00%, based on the lower of cost or market value of shares being redeemed.
Shares purchased as part of an exchange remain subject to any CDSC that applied
to the original purchase of those shares. There is no CDSC for Class R or Class
Y shares. Proceeds from the CDSCs are paid to PFD. For the year ended November
30, 2012, CDSCs in the amount of $11,416 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, 2012, the Fund's expenses
were not reduced under such arrangements.

6. Forward Foreign Currency Contracts

At November 30, 2012, 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 settlement hedge
contracts open during the year ended November 30, 2012 was $5,922,673. The
average value of portfolio hedge contracts open during the year ended November
30, 2012 was $381,284. At November 30, 2012, the Fund had no outstanding
portfolio hedges. At November 30, 2012, the Fund's gross forward currency
settlement contracts receivable and payable were $1,461,741 and $1,461,759,
respectively, resulting in a net payable of $18.

44 Pioneer Emerging Markets Fund | Annual Report | 11/30/12


7. Line of Credit Facility

The Fund, along with certain other funds in the Pioneer Family of Funds (the
Funds), participates in a committed, unsecured revolving line of credit
facility. Borrowings are used solely for temporary or emergency purposes. The
Fund may borrow up to the lesser of the amount available under the facility or
the limits set for borrowing by the Fund's prospectus and the 1940 Act. The
credit facility in effect until January 20, 2012 was in the amount of $165
million. Under such facility, interest on borrowings was payable at the higher
of the London Interbank Offered Rate (LIBOR) on the borrowing date plus 1.25% on
an annualized basis or the Federal Funds Rate on the borrowing date plus 1.25%
on an annualized basis. The credit facility in effect as of February 15, 2012 is
in the amount of $215 million. Under such facility, depending on the type of
loan, interest on borrowings is payable at 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
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, 2012, the Fund had no borrowings
under a credit facility.

46 Pioneer Emerging Markets Fund | Annual Report | 11/30/12


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, 2012, 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, 2012, 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, 2012, 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.

                                                          /s/ Ernst & Young LLP

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 2012 as the Trustees of the Fund
agreed on, among other things, an overall approach and timeline for the process.
In July 2012, 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 2012 and September 2012. After
reviewing and discussing the materials, the Trustees submitted a request for
additional information to PIM, and materials were provided in response to this
request. Meetings of the Independent Trustees of the Fund were held in July,
September, October, and November, 2012 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 13, 2012, based on their evaluation of the
information provided by PIM and third parties, the Trustees of the Fund,
including the Independent Trustees voting separately, unanimously approved the
renewal of the investment advisory agreement for another year. In considering
the renewal of the investment advisory agreement, the Trustees considered
various factors that they determined were relevant, including the factors
described below. The Trustees did not identify any single factor as the
controlling factor in determining to approve the renewal of the agreement.

Nature, Extent and Quality of Services

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

                     Pioneer Emerging Markets Fund | Annual Report | 11/30/12 49


by PIM's senior management to the Pioneer fund complex. In addition, the
Trustees considered PIM's plans to increase resources in its investment
management function and other enhancements to PIM's advisory capabilities.

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

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

Performance of the Fund

The Trustees considered the performance results of the Fund over various time
periods. They reviewed information comparing the Fund's performance with the
performance of its peer group of funds as classified by Morningstar, Inc.
(Morningstar), an independent provider of investment company data, and with the
performance of the Fund's benchmark index. The Trustees considered that the
Fund's annualized total return was in the fifth quintile of its Morningstar
category for the one, three and five year periods ended June 30, 2012. (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 considered reasons for the underperformance of the Fund relative to its
peer group and the steps recently taken by PIM in an effort to improve the
performance of the Fund, including changes to the Fund's portfolio management
team. 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 Trust Research
and Consulting, LLC (Strategic Insight), an independent third party.

50 Pioneer Emerging Markets Fund | Annual Report | 11/30/12


The Trustees considered that the Fund's management fee for the twelve months
ended June 30, 2012 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 noted that the Fund's management fee was only four basis points higher
than the median management fee paid by other funds in its Morningstar category.
The Trustees also noted information that showed that the current management fee
would be nine basis points above the median management fee of the Fund's
Morningstar category at a hypothetical asset level of $1 billion. The Trustees
also considered the breakpoint in the management fee schedule and the reduced
fee rate on assets over $1 billion. The Trustees considered that the Fund's
expense ratio for the twelve months ended June 30, 2012 was in the fifth
quintile relative to its Strategic Insight peer group for the comparable period.
The Trustees considered the impact of the Fund's non-management fee expenses on
the Fund's expense ratio, noting in particular the Fund's shareholder fees and
communications expenses.

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

Profitability

The Trustees considered information provided by PIM regarding the profitability
of PIM with respect to the advisory services provided by PIM to the Fund,
including the methodology used by PIM in allocating certain of its costs to the
management of the Fund. The Trustees also considered PIM's profit margin in
connection with the overall operation of the Fund. They

                     Pioneer Emerging Markets Fund | Annual Report | 11/30/12 51


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

Other Benefits

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

Conclusion

After consideration of the factors described above as well as other factors, the
Trustees, including all of the Independent Trustees, concluded that the
investment advisory agreement between PIM and the Fund, including the fees
payable thereunder, was fair and reasonable and voted to approve the proposed
renewal of the investment advisory agreement for the Fund.

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

                  SECTION I - POLICY PURPOSE AND APPLICABILITY

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

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

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

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

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

GENERAL AUDIT COMMITTEE APPROVAL POLICY:
o For all projects, the officers of the Funds and the Fund's auditors will each
  make an assessment to determine that any proposed projects will not impair
  independence.

o Potential services will be classified into the four non-restricted service
  categories and the "Approval of Audit, Audit-Related, Tax and Other
  Services" Policy above will be applied. Any services outside the specific
  pre-approved service subcategories set forth above must be specifically
  approved by the Audit Committee.

o At least quarterly, the Audit Committee shall review a report summarizing the
  services by service category, including fees, provided by the Audit firm as
  set forth in the above policy.

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


    (2) Disclose the percentage of services described in each of paragraphs (b)
   through (d) of this Item that were approved by the audit committee pursuant
   to paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X.

Non-Audit Services
Beginning with non-audit service contracts entered into on
or after May 6, 2003, the effective date of the new SEC pre-
approval rules, the Fund's audit committee is required to
pre-approve services to affiliates defined by SEC rules to
the extent that the services are determined to have a direct
impact on the operations or financial reporting of the Fund.
For the years ended November 30, 2012 and 2011, there
were no services provided to an affiliate that required the
Fund's audit committee pre-approval.

(f) If greater than 50 percent, disclose the percentage of hours expended on the
principal accountant's engagement to audit the registrant's financial statements
for the most recent fiscal year that were attributed to work performed by
persons other than the principal accountant's full-time, permanent employees.

N/A

(g) Disclose the aggregate non-audit fees billed by the registrant's accountant
for services rendered to the registrant, and rendered to the registrant's
investment adviser (not including any sub-adviser whose role is primarily
portfolio management and is subcontracted with or overseen by another investment
adviser), and any entity controlling, controlled by, or under common control
with the adviser that provides ongoing services to the registrant for each of
the last two fiscal years of the registrant.

The aggregate non-audit fees for the Fund and affiliates, as
previously defined, totaled approximately $8,290 in 2012
and $8,290 in 2011.

(h) Disclose whether the registrant's audit committee of the board of trustees
has considered whether the provision of non-audit services that were rendered to
the registrant's investment adviser (not including any subadviser whose role is
primarily portfolio management and is subcontracted with or overseen by another
investment adviser), and any entity controlling, controlled by, or under common
control with the investment adviser that provides ongoing services to the
registrant that were not pre-approved pursuant to paragraph (c)(7)(ii) of
Rule 2-01 of Regulation S-X is compatible with maintaining the principal
accountant's independence.

The Fund's audit committee of the Board of Trustees has
considered whether the provision of non-audit services that
were rendered to the Affiliates (as defined) that were not pre-
approved pursuant to paragraph (c)(7)(ii) of Rule 2-01 of
Regulation S-X is compatible with maintaining the principal
accountant's independence.

Item 5. Audit Committee of Listed Registrants

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

N/A

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