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

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

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

Pioneer Investment Management, Inc. (the "Adviser"), the fund's investment
adviser, is currently an indirect, wholly-owned subsidiary of UniCredit S.p.A.
("UniCredit"). On April 23, 2015, UniCredit announced that it signed a
preliminary and exclusive agreement with Banco Santander and affiliates of
Warburg Pincus and General Atlantic (the "Private Equity Firms") with respect
to Pioneer Investments ("Pioneer") and Santander Asset Management ("SAM") (the
"Transaction").

The Transaction, as described in the UniCredit announcement, will entail the
establishment of a holding company, with the name Pioneer Investments, to be
owned by UniCredit (50%) and the Private Equity Firms (50% between them). The
holding company will control Pioneer's U.S. operations, including the Adviser.
The holding company also will own 66.7% of Pioneer's and SAM's combined
operations outside the U.S., while Banco Santander will own directly the
remaining 33.3% stake. The completion of the Transaction is subject to the
signing of a definitive agreement, as well as certain regulatory and corporate
approvals, and other conditions.

Under the Investment Company Act of 1940, completion of the Transaction will
cause the fund's current investment advisory agreement with the Adviser to
terminate. In connection with the Transaction, the fund's Board of Trustees
will be asked to approve a new investment advisory agreement for the fund. If
approved by the Board, the fund's new investment advisory agreement will be

    sales charge may be subject to a contingent deferred sales charge of 1%.
    See "Sales charges."

2   The fund's investment adviser has contractually agreed to limit ordinary
    operating expenses (ordinary operating expenses means all fund expenses
    other than extraordinary expenses, such as litigation, taxes, brokerage
    commissions and acquired fund fees and expenses) to the extent required to
    reduce fund expenses to 0.85% and 1.10% of the average daily net assets
    attributable to Class A and Class R shares, respectively. These expense
    limitations are in effect through November 1, 2017. There can be no
    assurance that the adviser will extend the expense limitations beyond such
    times. While in effect, the arrangement may be terminated for a class only
    by agreement of the adviser and the Board of Trustees.


EXAMPLE
This example is intended to help you compare the cost of investing in the fund
with the cost of investing in other mutual funds. The example assumes that you
invest $10,000 in the fund for the time periods shown and then, except as
indicated, redeem all of your shares at the end of those periods. It also
assumes that (a) your investment has a 5% return each year and (b) the fund's
total annual operating expenses remain the same except for year one (which
considers the effect of the expense limitation). Although your actual costs may
be higher or lower, based on these assumptions your costs would be:

PORTFOLIO TURNOVER
The fund pays transaction costs, such as commissions, when it buys and sells
securities (or "turns over" its portfolio). A higher portfolio turnover rate
may indicate higher transaction costs and may result in higher taxes when fund
shares are held in a taxable account. These costs, which are not reflected in
annual fund operating expenses or in the example, affect the fund's
performance. During the most recent fiscal year, the fund's portfolio turnover
rate was 81% of the average value of its portfolio.


PRINCIPAL INVESTMENT STRATEGIES
Normally, the fund invests at least 80% of its net assets (plus the amount of
borrowings, if any, for investment purposes) in debt securities issued or
guaranteed by the U.S. government, its agencies and instrumentalities,
investment grade debt securities (including convertible debt) of corporate or
other issuers and cash, cash equivalents and other short-term holdings.
Derivative instruments that provide exposure to such securities or have similar
economic characteristics may be used to satisfy the fund's 80% policy.

The fund may invest a substantial portion of its assets in mortgage-related
securities, including "sub-prime" mortgages, and asset-backed securities. The
fund also may invest a portion of its assets in subordinated debt securities,
municipal securities, preferred securities, and event-linked bonds and other
insurance-linked securities.

The fund may invest up to 20% of its net assets in debt securities rated below
investment grade or, if unrated, of equivalent credit quality as determined by
the adviser (known as "junk bonds"), including securities that are in default.
The fund may invest up to 15% of its total assets in securities of non-U.S.
issuers, including up to 5% of its total assets in securities of emerging
market issuers.


                                       3


Fund summary

The fund may invest in securities with a broad range of maturities, and
maintains an average portfolio maturity which varies based upon the judgment of
the fund's investment adviser. The fund's investments may have fixed or
variable principal payments and all types of interest rate payment and reset
terms, including fixed rate, floating rate, inverse floating rate, zero coupon,
when-issued, delayed delivery, to be announced and forward commitment,
contingent, deferred and payment in kind and auction rate features. The fund's
investments may include instruments that allow for balloon payments or negative
amortization payments.

The fund may, but is not required to, use derivatives such as credit default
swaps and bond and interest rate futures. The fund may use derivatives for a
variety of purposes, including: in an attempt to hedge against adverse changes
in the market price of securities, interest rates or currency exchange rates;
as a substitute for purchasing or selling securities; to attempt to increase
the fund's return as a non-hedging strategy that may be considered speculative;
to manage portfolio characteristics; and as a cash flow management technique.
The fund may choose not to make use of derivatives for a variety of reasons,
and any use may be limited by applicable law and regulations. The fund may hold
cash or other short-term investments.

The adviser considers both broad economic and issuer specific factors in
selecting investments. In assessing the appropriate maturity, credit quality
and sector weighting of the fund's portfolio, the adviser considers a variety
of factors that are expected to influence economic activity and interest rates.
The adviser selects individual securities to buy and sell based upon such
factors as a security's yield, liquidity and rating, an assessment of credit
quality, and sector and issuer diversification.


PRINCIPAL RISKS OF INVESTING IN THE FUND
You could lose money on your investment in the fund. As with any mutual fund,
there is no guarantee that the fund will achieve its objectives.

MARKET RISK. The values of securities held by the fund may go up or down,
sometimes rapidly or unpredictably, due to general market conditions, such as
real or perceived adverse economic, political, or regulatory conditions,
inflation, changes in interest or currency rates, lack of liquidity in the bond
markets or adverse investor sentiment. In the past several years, financial
markets, such as those in the United States, Europe, Asia and elsewhere, have
experienced increased volatility, depressed valuations, decreased liquidity and
heightened uncertainty. Governmental and non-governmental


                                       4


issuers have defaulted on, or been forced to restructure, their debts. These
conditions may continue, recur, worsen or spread. The U.S. government and the
Federal Reserve, as well as certain foreign governments and their central
banks, have taken steps to support financial markets, including by keeping
interest rates at historically low levels. This and other government
intervention may not work as intended, particularly if the efforts are
perceived by investors as being unlikely to achieve the desired results. The
Federal Reserve recently has reduced its market support activities. Further
reduction or withdrawal of Federal Reserve or other U.S. or non-U.S.
governmental or central bank support, including interest rate increases, could
negatively affect financial markets generally, increase market volatility and
reduce the value and liquidity of securities in which the fund invests. Policy
and legislative changes in the U.S. and in other countries are affecting many
aspects of financial regulation, and may in some instances contribute to
decreased liquidity and increased volatility in the financial markets. The
impact of these changes on the markets, and the practical implications for
market participants, may not be fully known for some time. Economies and
financial markets throughout the world are becoming increasingly
interconnected. As a result, whether or not the fund invests in securities of
issuers located in or with significant exposure to countries experiencing
economic and financial difficulties, the value and liquidity of the fund's
investments may be negatively affected. The fund may experience a substantial
or complete loss on any individual security or derivative position.

INTEREST RATE RISK. Interest rates may go up, causing the value of the fund's
investments to decline (this risk generally will be greater for securities with
longer maturities or durations). Interest rates in the U.S. recently have been
historically low, so the fund faces a heightened risk that interest rates may
rise. A general rise in interest rates may cause investors to move out of fixed
income securities on a large scale, which could adversely affect the price and
liquidity of fixed income securities and could also result in increased
redemptions from the fund.

CREDIT RISK. If an issuer or guarantor of a security held by the fund or a
counterparty to a financial contract with the fund defaults on its obligation
to pay principal and/or interest, has its credit rating downgraded or is
perceived to be less creditworthy, or the credit quality or value of any
underlying assets declines, the value of your investment will typically
decline.

Fund summary

PREPAYMENT OR CALL RISK. Many issuers have a right to prepay their securities.
If interest rates fall, an issuer may exercise this right. If this happens, the
fund will not benefit from the rise in market price that normally accompanies a
decline in interest rates, and will be forced to reinvest prepayment proceeds
at a time when yields on securities available in the market are lower than the
yield on the prepaid security. The fund also may lose any premium it paid on
the security.

EXTENSION RISK. During periods of rising interest rates, the average life of
certain types of securities may be extended because of slower than expected
principal payments. This may lock in a below market interest rate, increase the
security's duration and reduce the value of the security.

LIQUIDITY RISK. Some securities and derivatives held by the fund may be
impossible or difficult to purchase, sell or unwind, particularly during times
of market turmoil. An instrument's liquidity may be affected by reduced trading
volume, a relative lack of market makers or legal restrictions, and illiquid
securities and derivatives also may be difficult to value. Liquidity risk may
be magnified in a rising interest rate environment. If the fund is forced to
sell an illiquid asset or unwind a derivatives position to meet redemption
requests or other cash needs, the fund may be forced to sell at a loss.

PORTFOLIO SELECTION RISK. The adviser's judgment about the quality, relative
yield, relative value or market trends affecting a particular sector or region,
market segment, security or about interest rates generally may prove to be
incorrect.

U.S. TREASURY OBLIGATIONS RISK. The market value of direct obligations of the
U.S. Treasury may vary due to changes in interest rates. In addition, changes
to the financial condition or credit rating of the U.S. government may cause
the value of the fund's investments in obligations issued by the U.S. Treasury
to decline.

U.S. GOVERNMENT AGENCY OBLIGATIONS RISK. The fund invests in obligations issued
by agencies and instrumentalities of the U.S. government. Government-sponsored
entities such as Federal National Mortgage Association ("FNMA"), Federal Home
Loan Mortgage Corporation ("FHLMC") and the Federal Home Loan Banks ("FHLBs"),
although chartered or sponsored by Congress, are not funded by congressional
appropriations and the debt and mortgage-backed securities issued by them are
neither guaranteed nor issued by the U.S. government. Such debt and
mortgage-backed securities


                                       6


are subject to the risk of default on the payment of interest and/or principal,
similar to debt of private issuers. Although the U.S. government has provided
financial support to FNMA and FHLMC in the past, there can be no assurance that
it will support these or other government-sponsored entities in the future.

MORTGAGE-RELATED AND ASSET-BACKED SECURITIES RISK. The value of
mortgage-related and asset-backed securities will be influenced by factors
affecting the housing market and the assets underlying such securities. As a
result, during periods of declining asset value, difficult or frozen credit
markets, swings in interest rates, or deteriorating economic conditions,
mortgage-related and asset-backed securities may decline in value, face
valuation difficulties, become more volatile and/or become illiquid.
Mortgage-backed securities tend to be more sensitive to changes in interest
rate than other types of debt securities. These securities are also subject to
prepayment and extension risks. Some of these securities may receive little or
no collateral protection from the underlying assets and are thus subject to the
risk of default. The risk of such defaults is generally higher in the case of
mortgage-backed investments that include so-called "sub-prime" mortgages. The
structure of some of these securities may be complex and there may be less
available information than for other types of debt securities. Upon the
occurrence of certain triggering events or defaults, the fund may become the
holder of underlying assets at a time when those assets may be difficult to
sell or may be sold only at a loss.

RISKS OF INSTRUMENTS THAT ALLOW FOR BALLOON PAYMENTS OR NEGATIVE AMORTIZATION
PAYMENTS. Certain debt instruments allow for balloon payments or negative
amortization payments. Such instruments permit the borrower to avoid paying
currently a portion of the interest accruing on the instrument. While these
features make the debt instrument more affordable to the borrower in the near
term, they increase the risk that the borrower will be unable to make the
resulting higher payment or payments that become due at the maturity of the
loan.

HIGH YIELD OR "JUNK" BOND RISK. Debt securities that are below investment
grade, called "junk bonds," are speculative, have a higher risk of default or
are already in default, tend to be less liquid and are more difficult to value
than higher grade securities. Junk bonds tend to be volatile and more
susceptible to adverse events and negative sentiments. These risks are more
pronounced for securities that are already in default.

Fund summary

RISKS OF INVESTING IN FLOATING RATE LOANS. Floating rate loans and similar
investments may be illiquid or less liquid than other investments and difficult
to value. The value of collateral, if any, securing a floating rate loan can
decline or may be insufficient to meet the issuer's obligations or may be
difficult to liquidate. No active trading market may exist for many floating
rate loans, and many loans are subject to restrictions on resale. Market
quotations for these securities may be volatile and/or subject to large spreads
between bid and ask prices. Any secondary market may be subject to irregular
trading activity and extended trade settlement periods.

RISKS OF INVESTING IN INSURANCE-LINKED SECURITIES. The return of principal and
the payment of interest on "event-linked" bonds and other insurance-linked
securities are contingent on the non-occurrence of a pre-defined "trigger"
event, such as a hurricane or an earthquake of a specific magnitude or other
event that leads to physical or economic loss. If a trigger event, as defined
within the terms of an event-linked bond, involves losses or other metrics
exceeding a specific magnitude in the geographic region and time period
specified, the fund may lose a portion or all of its accrued interest and/or
principal invested in the event-linked bond. In addition to the specified
trigger events, event-linked bonds may expose the fund to other risks,
including but not limited to issuer (credit) default, adverse regulatory or
jurisdictional interpretations and adverse tax consequences. Certain
insurance-linked securities may have limited liquidity, or may be illiquid. The
fund has limited transparency into the individual contracts underlying certain
insurance-linked securities, which may make the risk assessment of such
securities more difficult. Certain insurance-linked securities may be difficult
to value.

RISKS OF SUBORDINATED SECURITIES. A holder of securities that are subordinated
or "junior" to more senior securities of an issuer is entitled to payment after
holders of more senior securities of the issuer. Subordinated securities are
more likely to suffer a credit loss than non-subordinated securities of the
same issuer, any loss incurred by the subordinated securities is likely to be
proportionately greater, and any recovery of interest or principal may take
more time. As a result, even a perceived decline in creditworthiness of the
issuer is likely to have a greater impact on them.

MUNICIPAL SECURITIES RISK. The municipal bond market can be susceptible to
unusual volatility, particularly for lower-rated and unrated securities.
Liquidity can be reduced unpredictably in response to overall economic
conditions or credit tightening. Municipal issuers may be adversely affected


                                       8


by rising health care costs, increasing unfunded pension liabilities, and by
the phasing out of federal programs providing financial support. Unfavorable
conditions and developments relating to projects financed with municipal
securities can result in lower revenues to issuers of municipal securities,
potentially resulting in defaults. Issuers often depend on revenues from these
projects to make principal and interest payments. The value of municipal
securities can also be adversely affected by changes in the financial condition
of one or more individual municipal issuers or insurers of municipal issuers,
regulatory and political developments, tax law changes or other legislative
actions, and by uncertainties and public perceptions concerning these and other
factors. Municipal issuers may be more susceptible to downgrades or defaults
during recessions or similar periods of economic stress. In recent periods, an
increasing number of municipal issuers in the United States have defaulted on
obligations and commenced insolvency proceedings. Financial difficulties of
municipal issuers may continue or get worse. To the extent the fund invests
significantly in a single state or in securities the payments on which are
dependent upon a single project or source of revenues, or that relate to a
sector or industry, the fund will be more susceptible to associated risks and
developments.

RISKS OF ZERO COUPON BONDS, PAYMENT IN KIND, DEFERRED AND CONTINGENT PAYMENT
SECURITIES. These securities may be more speculative and may fluctuate more in
value than securities which pay income periodically and in cash. In addition,
although the fund receives no periodic cash payments on such securities, the
fund is deemed for tax purposes to receive income from such securities, which
applicable tax rules require the fund to distribute to shareholders. Such
distributions may be taxable when distributed to shareholders.

RISKS OF INVESTING IN WHEN-ISSUED, DELAYED DELIVERY, TO BE ANNOUNCED AND
FORWARD COMMITMENT TRANSACTIONS. The market value of these transactions may
increase or decrease as a result of changes in interest rates. These
transactions involve risk of loss if the value of the underlying security
changes unfavorably before the settlement date or if the assets set aside to
pay for these securities decline in value prior to the settlement date.
Therefore, these transactions may have a leveraging effect on the fund, making
the value of an investment in the fund more volatile and increasing the fund's
overall investment exposure. There is also a risk that the other party to the
transaction will default on its obligation to purchase or sell the security,
which may result in the fund missing the opportunity to obtain a favorable
price or yield elsewhere.

Fund summary

RISKS OF NON-U.S. INVESTMENTS. Investing in non-U.S. issuers, or in U.S.
issuers that have significant exposure to foreign markets, may involve unique
risks compared to investing in securities of U.S. issuers. These risks are more
pronounced for issuers in emerging markets or to the extent that the fund
invests significantly in one region or country. These risks may include
different financial reporting practices and regulatory standards, less liquid
trading markets, extreme price volatility, currency risks, changes in economic,
political, regulatory and social conditions, sustained economic downturns,
financial instability, tax burdens, and investment and repatriation
restrictions. Lack of information and less market regulation also may affect
the value of these securities. Withholding and other non-U.S. taxes may
decrease the fund's return. Non-U.S. issuers may be located in parts of the
world that have historically been prone to natural disasters. Investing in
depositary receipts is subject to many of the same risks as investing directly
in non-U.S. issuers. Depositary receipts may involve higher expenses and may
trade at a discount (or premium) to the underlying security.

RISKS OF CONVERTIBLE SECURITIES. The market values of convertible securities
tend to decline as interest rates increase and, conversely, to increase as
interest rates decline. A downturn in equity markets may cause the price of
convertible securities to decrease relative to other fixed income securities.

PREFERRED STOCKS RISK. Preferred stocks may pay fixed or adjustable rates of
return. Preferred stocks are subject to issuer-specific and market risks
applicable generally to equity securities. In addition, a company's preferred
stocks generally pay dividends only after the company makes required payments
to holders of its bonds and other debt. Thus, the value of preferred stocks
will usually react more strongly than bonds and other debt to actual or
perceived changes in the company's financial condition or prospects. The market
value of preferred stocks generally decreases when interest rates rise.
Preferred stocks of smaller companies may be more vulnerable to adverse
developments than preferred stocks of larger companies.

DERIVATIVES RISK. Using swaps, futures and other derivatives can increase fund
losses and reduce opportunities for gains when market prices, interest rates or
the derivative instruments themselves behave in a way not anticipated by the
fund. Using derivatives may increase the volatility of the fund's net asset
value and may not provide the result intended. Derivatives may have a
leveraging effect on the fund. Some derivatives have the potential for
unlimited loss, regardless of the size of the fund's initial investment.
Changes in a derivative's value may not correlate well with the referenced
asset or


                                       10


metric. The fund also may have to sell assets at inopportune times to satisfy
its obligations. Derivatives may be difficult to sell, unwind or value, and the
counterparty may default on its obligations to the fund. The U.S. government is
in the process of adopting and implementing regulations governing derivatives
markets, including mandatory clearing of certain derivatives, margin and
reporting requirements. The ultimate impact of the regulations remains unclear.
Additional regulation of derivatives may make them more costly, may limit their
availability, may disrupt markets or may otherwise adversely affect their value
or performance.

CREDIT DEFAULT SWAP RISK. Credit default swap contracts, a type of derivative
instrument, involve special risks and may result in losses to the fund. Credit
default swaps may in some cases be illiquid, and they increase credit risk
since the fund has exposure to the issuer of the referenced obligation and
either the counterparty to the credit default swap or, if it is a cleared
transaction, the brokerage firm through which the trade was cleared and the
clearing organization that is the counterparty to that trade.

RISKS OF INVESTING IN INVERSE FLOATING RATE OBLIGATIONS. The interest rate on
inverse floating rate obligations will generally decrease as short-term
interest rates increase, and increase as short-term rates decrease. Due to
their leveraged structure, the sensitivity of the market value of an inverse
floating rate obligation to changes in interest rates is generally greater than
a comparable long-term bond issued by the same issuer and with similar credit
quality, redemption and maturity provisions. Inverse floating rate obligations
may be volatile and involve leverage risk.

LEVERAGING RISK. The value of your investment may be more volatile and other
risks tend to be compounded if the fund borrows or uses derivatives or other
investments that have embedded leverage. Leverage generally magnifies the
effect of any increase or decrease in the value of the fund's underlying assets
and creates a risk of loss of value on a larger pool of assets than the fund
would otherwise have, potentially resulting in the loss of all assets. Engaging
in such transactions may cause the fund to liquidate positions when it may not
be advantageous to do so to satisfy its obligations or meet segregation
requirements.

REPURCHASE AGREEMENT RISK. In the event that the other party to a repurchase
agreement defaults on its obligations, the fund may encounter delay and incur
costs before being able to sell the security. Such a delay may involve


                                       11


Fund summary

loss of interest or a decline in price of the security. In addition, if the
fund is characterized by a court as an unsecured creditor, it would be at risk
of losing some or all of the principal and interest involved in the
transaction.

MARKET SEGMENT RISK. To the extent the fund emphasizes, from time to time,
investments in a market segment, the fund will be subject to a greater degree
to the risks particular to that segment, and may experience greater market
fluctuation than a fund without the same focus.

VALUATION RISK. The sales price the fund could receive for any particular
portfolio investment may differ from the fund's last valuation of the
investment, particularly for illiquid securities and securities that trade in
thin or volatile markets or that are valued using a fair value methodology.
Investors who purchase or redeem fund shares on days when the fund is holding
fair-valued securities may receive fewer or more shares or lower or higher
redemption proceeds than they would have received if the fund had not
fair-valued the security or had used a different valuation methodology.

EXPENSE RISK. Your actual costs of investing in the fund may be higher than the
expenses shown in "Annual fund operating expenses" for a variety of reasons.
For example, expense ratios may be higher than those shown if overall net
assets decrease. Net assets are more likely to decrease and fund expense ratios
are more likely to increase when markets are volatile.

Please note that there are many other factors that could adversely affect your
investment and that could prevent the fund from achieving its goals.

An investment in the fund is not a bank deposit and is not insured or
guaranteed by the Federal Deposit Insurance Corporation or any other government
agency.

More on the fund's investment objectives
and strategies


INVESTMENT OBJECTIVES
To provide current income from an investment grade portfolio with due regard to
preservation of capital and prudent investment risk. The fund also seeks a
relatively stable level of dividends; however, the level of dividends will be
maintained only if consistent with preserving the investment grade quality of
the portfolio.


PRINCIPAL INVESTMENT STRATEGIES
The fund invests primarily in:
o debt securities issued or guaranteed by the U.S. government or its agencies
  and instrumentalities,
o debt securities, including convertible debt, of corporate and other issuers
  rated at least investment grade at the time of investment, and comparably
  rated commercial paper,
o cash and cash equivalents, certificates of deposit, repurchase agreements
  maturing in one week or less and bankers' acceptances.

Normally, the fund invests at least 80% of its net assets (plus the amount of
borrowings, if any, for investment purposes) in these securities. Derivative
instruments that provide exposure to such securities or have similar economic
characteristics may be used to satisfy the fund's 80% policy.

The fund will provide written notice to shareholders at least 60 days prior to
any change to the requirement that it invest at least 80% of its assets as
described above.

Cash and cash equivalents include cash balances, accrued interest and
receivables for items such as the proceeds, not yet received, from the sale of
the fund's portfolio investments.

U.S. government securities include U.S. Treasury obligations, such as bills,
bonds and notes, and obligations issued or guaranteed by U.S. government
agencies or instrumentalities. These obligations may be supported by:
o the full faith and credit of the U.S. Treasury, such as securities issued by
  the Government National Mortgage Association ("GNMA");
o the authority of the U.S. government to purchase certain obligations of the
  issuer, such as securities issued by the Federal National Mortgage
  Association ("FNMA") and the Federal Home Loan Mortgage Corporation
  ("FHLMC");
o the limited authority of the issuer to borrow from the U.S. Treasury; or

                                       16


o only the credit of the issuer.

The fund may invest a substantial portion of its assets in mortgage-related
securities, including "sub-prime" mortgages, and asset-backed securities.
Mortgage-backed securities represent interests in pools of mortgage loans
assembled for sale to investors by various U.S. governmental agencies,
government-related organizations and private issuers.

The fund may invest in securities with a broad range of maturities and
maintains an average portfolio maturity which varies based upon the judgment of
Pioneer Investment Management, Inc. (Pioneer), the fund's investment adviser.
The fund's investments may have fixed or variable principal payments and all
types of interest rate payment and reset terms, including fixed rate, floating
rate, inverse floating rate, zero coupon, when-issued, delayed delivery, to be
announced and forward commitment, contingent, deferred and payment in kind and
auction rate features. The fund's investments may include instruments that
allow for balloon payments or negative amortization payments.

The fund may invest up to 20% of its net assets in debt securities rated below
investment grade or, if unrated, of equivalent credit quality as determined by
Pioneer (known as "junk bonds"). The fund's investment in debt securities rated
below investment grade may include debt securities rated "D" or better, or
comparable unrated securities. Debt securities rated "D" are in default.

The fund may invest a portion of its assets in subordinated debt securities,
municipal securities, preferred securities, and event-linked bonds and other
insurance-linked securities.

The fund may invest up to 15% of its total assets in securities of non-U.S.
issuers. Up to 5% of the fund's total assets may be invested in securities of
emerging market issuers. The fund does not count securities of Canadian issuers
against the limit on investment in securities of non-U.S. issuers.

Pioneer considers both broad economic and issuer specific factors in selecting
a portfolio designed to achieve the fund's investment objectives. In assessing
the appropriate maturity, rating and sector weighting of the fund's portfolio,
Pioneer considers a variety of factors that are expected to influence economic
activity and interest rates. These factors include fundamental economic
indicators, such as the rates of economic growth and inflation, Federal Reserve
monetary policy and the relative value of the U.S. dollar compared to other

of the securities (such as yields compared to U.S. Treasuries or comparable
issues), liquidity and rating, sector and issuer diversification. Pioneer also
employs fundamental research to assess an issuer's credit quality, taking into
account financial condition and profitability, future capital needs, potential
for change in rating, industry outlook, the competitive environment and
management ability. In making these portfolio decisions, Pioneer relies on the
knowledge, experience and judgment of its staff and the staff of its affiliates
who have access to a wide variety of research.

Except for the fund's investment objective, the fund's investment strategies
and policies may be changed from time to time without shareholder approval,
unless specifically stated otherwise in this prospectus or in the SAI.


INVESTMENT GRADE SECURITIES
A debt security is considered investment grade if it is:
o Rated BBB or higher at the time of purchase by Standard & Poor's Financial
  Services LLC;
o Rated the equivalent rating by a nationally recognized statistical rating
  organization; or
o Determined to be of equivalent credit quality by Pioneer

Securities in the lowest category of investment grade (i.e., BBB) are
considered to have speculative characteristics.


BELOW INVESTMENT GRADE SECURITIES ("JUNK BONDS")
The fund may invest in debt securities rated below investment grade or, if
unrated, of equivalent quality as determined by Pioneer. A debt security is
below investment grade if it is rated BB or lower by Standard & Poor's
Financial Services LLC or the equivalent rating by another nationally
recognized statistical rating organization or determined to be of equivalent
credit quality by Pioneer. Debt securities rated below investment grade are
commonly referred to as "junk bonds" and are considered speculative. Below
investment grade debt securities involve greater risk of loss, are subject to
greater price volatility and are less liquid, especially during periods of
economic uncertainty or change, than higher quality debt securities. Below
investment grade securities also may be more difficult to value.


DEBT RATING CONSIDERATIONS
For purposes of the fund's credit quality policies, if a security receives
different ratings from nationally recognized statistical rating organizations,
the fund will use the rating chosen by the portfolio manager as most
representative of the security's credit quality. The ratings of nationally


                                       18


recognized statistical rating organizations represent their opinions as to the
quality of the securities that they undertake to rate and may not accurately
describe the risks of the securities. A rating organization may have a conflict
of interest with respect to a security for which it assigns a quality rating.
In addition, there may be a delay between a change in the credit quality of a
security or other asset and a change in the quality rating assigned to the
security or other asset by a rating organization. If a rating organization
changes the quality rating assigned to one or more of the fund's securities,
Pioneer will consider if any action is appropriate in light of the fund's
investment objectives and policies. An investor can still lose significant
amounts when investing in investment grade securities. These ratings are used
as criteria for the selection of portfolio securities, in addition to Pioneer's
own assessment of the credit quality of potential investments.


MORTGAGE-BACKED SECURITIES
The fund may invest in mortgage-backed securities. Mortgage-backed securities
may be issued by private issuers, by government-sponsored entities such as the
Federal National Mortgage Association ("FNMA") or Federal Home Loan Mortgage
Corporation ("FHLMC") or by agencies of the U.S. government, such as the
Government National Mortgage Association ("GNMA"). Mortgage-backed securities
represent direct or indirect participation in, or are collateralized by and
payable from, mortgage loans secured by real property. The fund's investments
in mortgage-related securities may include mortgage derivatives and structured
securities.

The fund may invest in collateralized mortgage obligations (CMOs). A CMO is a
mortgage-backed bond that is issued in multiple classes, each with a specified
fixed or floating interest rate and a final scheduled distribution date. The
holder of an interest in a CMO is entitled to receive specified cash flows from
a pool of underlying mortgages or other mortgage-backed securities. Depending
upon the class of CMO purchased, the holder may be entitled to payment before
the cash flow from the pool is used to pay holders of other classes of the CMO
or, alternatively, the holder may be paid only to the extent that there is cash
remaining after the cash flow has been used to pay other classes. A
subordinated interest may serve as a credit support for the senior securities
purchased by other investors.

More on the fund's investment objectives
and strategies

ASSET-BACKED SECURITIES
The fund may invest in asset-backed securities. Asset-backed securities
represent participations in, or are secured by and payable from, assets such as
installment sales or loan contracts, leases, credit card receivables and other
categories of receivables. The fund's investments in asset-backed securities
may include derivative and structured securities.

The fund may invest in asset-backed securities issued by special entities, such
as trusts, that are backed by a pool of financial assets. The fund may invest
in collateralized debt obligations (CDOs), which include collateralized bond
obligations (CBOs), collateralized loan obligations (CLOs) and other similarly
structured securities. A CDO is a trust backed by a pool of fixed income
securities. The trust typically is split into two or more portions, called
tranches, which vary in credit quality, yield, credit support and right to
repayment of principal and interest. Lower tranches pay higher interest rates
but represent lower degrees of credit quality and are more sensitive to the
rate of defaults in the pool of obligations. Certain CDOs may use derivatives,
such as credit default swaps, to create synthetic exposure to assets rather
than holding such assets directly.


FLOATING RATE LOANS
Floating rate loans are provided by banks and other financial institutions to
large corporate customers in connection with recapitalizations, acquisitions,
and refinancings. These loans are generally acquired as a participation
interest in, or assignment of, loans originated by a lender or other financial
institution. These loans are rated below investment grade, but typically are
secured with specific collateral and have a senior position in the capital
structure of the borrower. These loans typically have rates of interest that
are reset periodically by reference to a base lending rate, such as the London
Interbank Offered Rate (LIBOR), plus a premium.


SUBORDINATED SECURITIES
The fund may invest in securities that are subordinated or "junior" to more
senior securities of the issuer. The investor in a subordinated security of an
issuer is entitled to payment after other holders of debt in that issuer.


NON-U.S. INVESTMENTS
The fund may invest in securities of non-U.S. issuers, including securities of
emerging markets issuers. Non-U.S. issuers are issuers that are organized and
have their principal offices outside of the United States. Non-U.S. securities
may be issued by non-U.S. governments, banks or corporations,


                                       20


or private issuers, and certain supranational organizations, such as the World
Bank and the European Union. The fund considers emerging market issuers to
include issuers organized under the laws of an emerging market country, issuers
with a principal office in an emerging market country, issuers that derive at
least 50% of their gross revenues or profits from goods or services produced in
emerging markets, and emerging market governmental issuers.


EVENT-LINKED BONDS AND OTHER INSURANCE-LINKED SECURITIES
The fund may invest in "event-linked" bonds, which sometimes are referred to as
"insurance-linked" or "catastrophe" bonds. Event-linked bonds are debt
obligations for which the return of principal and the payment of interest are
contingent on the non-occurrence of a pre-defined "trigger" event, such as a
hurricane or an earthquake of a specific magnitude or other event that leads to
physical or economic loss. For some event-linked bonds, the trigger event's
magnitude may be based on losses to a company or industry, industry indexes or
readings of scientific instruments rather than specified actual losses. The
fund is entitled to receive principal and interest payments so long as no
trigger event occurs of the description and magnitude specified by the
instrument.

Event-linked bonds may be issued by government agencies, insurance companies,
reinsurers, special purpose corporations or other on-shore or off-shore
entities. The fund may invest in interests in pooled entities that invest
primarily in event-linked bonds.

Event-linked bonds are typically rated by at least one nationally recognized
statistical rating agency, but also may be unrated. The rating for an
event-linked bond primarily reflects the rating agency's calculated probability
that a pre-defined trigger event will occur. This rating also assesses the
event-linked bond's credit risk and the model used to calculate the probability
of a trigger event.

In addition to event-linked bonds, the fund may also invest in other
insurance-linked securities, including structured reinsurance instruments such
as quota share instruments (a form of proportional reinsurance whereby an
investor participates in the premiums and losses of a reinsurer's portfolio of
catastrophe-oriented policies, sometimes referred to as "reinsurance sidecars")
and collateralized reinsurance investments, industry loss warranties, and other
insurance- and reinsurance-related securities. Quota share instruments and
other structured reinsurance instruments generally will be considered illiquid
securities by the fund.

and strategies

ZERO COUPON SECURITIES
The fund may invest in zero coupon securities. Zero coupon securities are debt
instruments that do not pay interest during the life of the security but are
issued at a discount from the amount the investor will receive when the issuer
repays the amount borrowed (the face value). The discount approximates the
total amount of interest that would be paid at an assumed interest rate.


DERIVATIVES
The fund may, but is not required to, use futures and options on securities,
indices and currencies, forward foreign currency exchange contracts, swaps and
other derivatives. The fund also may enter into credit default swaps, which can
be used to acquire or to transfer the credit risk of a security or index of
securities without buying or selling the security or securities comprising the
relevant index. A derivative is a security or instrument whose value is
determined by reference to the value or the change in value of one or more
securities, currencies, indices or other financial instruments. The fund may
use derivatives for a variety of purposes, including:
o In an attempt to hedge against adverse changes in the market prices of
  securities, interest rates or currency exchange rates
o As a substitute for purchasing or selling securities
o To attempt to increase the fund's return as a non-hedging strategy that may
  be considered speculative
o To manage portfolio characteristics (for example, the duration or credit
  quality of the fund's portfolio)
o As a cash flow management technique

The fund may choose not to make use of derivatives for a variety of reasons,
and any use may be limited by applicable law and regulations.


INVERSE FLOATING RATE OBLIGATIONS
The fund may invest in inverse floating rate obligations (a type of derivative
instrument). The interest rate on inverse floating rate obligations will
generally decrease as short-term interest rates increase, and increase as
short-term rates decrease. Due to their leveraged structure, the sensitivity of
the market value of an inverse floating rate obligation to changes in interest
rates is generally greater than a comparable long-term bond issued by the same
issuer and with similar credit quality, redemption and maturity provisions.
Inverse floating rate obligations may be volatile and involve leverage risk.


                                       22


CASH MANAGEMENT AND TEMPORARY INVESTMENTS
Normally, the fund invests substantially all of its assets to meet its
investment objectives. The fund may invest the remainder of its assets in
securities with remaining maturities of less than one year or cash equivalents,
or may hold cash. For temporary defensive purposes, including during periods of
unusual cash flows, the fund may depart from its principal investment
strategies and invest part or all of its assets in these securities or may hold
cash. The fund may adopt a defensive strategy when the adviser believes
securities in which the fund normally invests have special or unusual risks or
are less attractive due to adverse market, economic, political or other
conditions. During such periods, it may be more difficult for the fund to
achieve its investment objective.


ADDITIONAL INVESTMENT STRATEGIES
In addition to the principal investment strategies discussed above, the fund
may also use other techniques, including the following non-principal investment
strategies.


REPURCHASE AGREEMENTS
In a repurchase agreement, the fund purchases securities from a broker/dealer
or a bank, called the counterparty, upon the agreement of the counterparty to
repurchase the securities from the fund at a later date, and at a specified
price, which is typically higher than the purchase price paid by the fund. The
securities purchased serve as the fund's collateral for the obligation of the
counterparty to repurchase the securities. If the counterparty does not
repurchase the securities, the fund is entitled to sell the securities, but the
fund may not be able to sell them for the price at which they were purchased,
thus causing a loss. Additionally, if the counterparty becomes insolvent, there
is some risk that the fund will not have a right to the securities, or the
immediate right to sell the securities.


REVERSE REPURCHASE AGREEMENTS AND BORROWING
The fund may enter into reverse repurchase agreements pursuant to which the
fund transfers securities to a counterparty in return for cash, and the fund
agrees to repurchase the securities at a later date and for a higher price.
Reverse repurchase agreements are treated as borrowings by the fund, are a form
of leverage and may make the value of an investment in the fund more volatile
and increase the risks of investing in the fund. The fund also may borrow money
from banks or other lenders for temporary purposes. The fund may borrow up to
33 1/3% of its total assets. Entering


                                       23


More on the fund's investment objectives
and strategies

into reverse repurchase agreements and other borrowing transactions may cause
the fund to liquidate positions when it may not be advantageous to do so in
order to satisfy its obligations or meet segregation requirements.


SHORT-TERM TRADING
The fund usually does not trade for short-term profits. The fund will sell an
investment, however, even if it has only been held for a short time, if it no
longer meets the fund's investment criteria. If the fund does a lot of trading,
it may incur additional operating expenses, which would reduce performance, and
could cause shareowners to incur a higher level of taxable income or capital
gains.

PRINCIPAL INVESTMENT RISKS
You could lose money on your investment in the fund. As with any mutual fund,
there is no guarantee that the fund will achieve its objectives.

MARKET RISK. The values of securities held by the fund may go up or down,
sometimes rapidly or unpredictably, due to general market conditions, such as
real or perceived adverse economic, political, or regulatory conditions,
inflation, changes in interest or currency rates, lack of liquidity in the bond
markets or adverse investor sentiment. Changes in market conditions may not
have the same impact on all types of securities. The values of securities may
also fall due to specific conditions that affect a particular sector of the
securities market or a particular issuer. In the past several years, financial
markets, such as those in the United States, Europe, Asia and elsewhere, have
experienced increased volatility, depressed valuations, decreased liquidity and
heightened uncertainty. Governmental and non-governmental issuers have
defaulted on, or been forced to restructure, their debts. These conditions may
continue, recur, worsen or spread. The U.S. government and the Federal Reserve,
as well as certain foreign governments and their central banks, have taken
steps to support financial markets, including by keeping interest rates at
historically low levels. This and other government intervention may not work as
intended, particularly if the efforts are perceived by investors as being
unlikely to achieve the desired results. The Federal Reserve recently has
reduced its market support activities. Further reduction or withdrawal of
Federal Reserve or other U.S. or non-U.S. governmental or central bank support,
including interest rate increases, could negatively affect financial markets
generally, increase market volatility and reduce the value and liquidity of
securities in which the fund invests. Policy and legislative changes in the
U.S. and in other countries are affecting many aspects of financial regulation,
and may in some instances contribute to decreased liquidity and increased
volatility in the financial markets. The impact of these changes on the
markets, and the practical implications for market participants, may not be
fully known for some time. Economies and financial markets throughout the world
are becoming increasingly interconnected. As a result, whether or not the fund
invests in securities of issuers located in or with significant exposure to
countries experiencing economic and financial difficulties, the value and
liquidity of the fund's investments may be negatively affected. The fund may
experience a substantial or complete loss on any individual security or
derivative position. Particularly during periods of declining or illiquid
markets, the fund may experience periods of heavy redemptions that could cause
the fund to liquidate its assets at


                                       25


More on the risks of investing in the fund

inopportune times or at a loss or depressed value, and could cause the
remaining shareholders in the fund to lose money. This redemption risk is
greater to the extent that the fund has investors with large shareholdings,
short investment horizons or unpredictable cash flow needs.

INTEREST RATE RISK. The market prices of securities may fluctuate significantly
when interest rates change. When interest rates rise, the value of fixed income
securities and therefore the value of your investment in the fund, generally
falls. Interest rates have been historically low, so the fund faces a
heightened risk that interest rates may rise. A general rise in interest rates
may cause investors to move out of fixed income securities on a large scale,
which could adversely affect the price and liquidity of fixed income securities
and could also result in increased redemptions from the fund. A change in
interest rates will not have the same impact on all fixed income securities.
Generally, the longer the maturity or duration of a fixed income security, the
greater the impact of a rise in interest rates on the security's value. For
example, if interest rates increase by 1%, the value of a fund's portfolio with
a portfolio duration of ten years would be expected to decrease by 10%, all
other things being equal. Calculations of duration and maturity may be based on
estimates and may not reliably predict a security's price sensitivity to
changes in interest rates. Moreover, securities can change in value in response
to other factors, such as credit risk. In addition, different interest rate
measures (such as short- and long-term interest rates and U.S. and foreign
interest rates), or interest rates on different types of securities or
securities of different issuers, may not necessarily change in the same amount
or in the same direction. When interest rates go down, the income received by
the fund, and the fund's yield, may decline. Also, when interest rates decline,
investments made by the fund may pay a lower interest rate, which would reduce
the income received and distributed by the fund.

Certain fixed income securities pay interest at variable or floating rates.
Variable rate securities tend to reset at specified intervals, while floating
rate securities may reset whenever there is a change in a specified index rate.
In most cases, these reset provisions reduce the impact of changes in market
interest rates on the value of the security. However, some securities do not
track the underlying index directly, but reset based on formulas that may
produce a leveraging effect; others may also provide for interest payments that
vary inversely with market rates. The market prices of these securities may
fluctuate significantly when interest rates change. Yield generated by the fund
may decline due to a decrease in market interest rates.


                                       26


CREDIT RISK. If an obligor (such as the issuer itself or a party offering
credit enhancement) for a security held by the fund fails to pay, otherwise
defaults, is perceived to be less creditworthy, becomes insolvent or files for
bankruptcy, a security's credit rating is downgraded or the credit quality or
value of an underlying asset declines, the value of your investment could
decline. If the fund enters into financial contracts (such as certain
derivatives, repurchase agreements, reverse repurchase agreements, and
when-issued, delayed delivery and forward commitment transactions), the fund
will be subject to the credit risk presented by the counterparty. In addition,
the fund may incur expenses in an effort to protect the fund's interests or to
enforce its rights. Credit risk is broadly gauged by the credit ratings of the
securities in which the fund invests. However, ratings are only the opinions of
the companies issuing them and are not guarantees as to quality. Securities
rated in the lowest category of investment grade (Baa/BBB) may possess certain
speculative characteristics.

PREPAYMENT OR CALL RISK. Many fixed income securities give the issuer the
option to prepay or call the security prior to its maturity date. Issuers often
exercise this right when interest rates fall. Accordingly, if the fund holds a
fixed income security that can be prepaid or called prior to its maturity date,
it will not benefit fully from the increase in value that other fixed income
securities generally experience when interest rates fall. Upon prepayment of
the security, the fund also would be forced to reinvest the proceeds at then
current yields, which would be lower than the yield of the security that was
prepaid or called. In addition, if the fund purchases a fixed income security
at a premium (at a price that exceeds its stated par or principal value), the
fund may lose the amount of the premium paid in the event of prepayment.

EXTENSION RISK. During periods of rising interest rates, the average life of
certain types of securities may be extended because of slower than expected
principal payments. This may lock in a below market interest rate, increase the
security's duration and reduce the value of the security.

To the extent the fund invests significantly in mortgage-related and
asset-backed securities, its exposure to extension risks may be greater than if
it invested in other fixed income securities.

LIQUIDITY RISK. Liquidity risk exists when particular investments are
impossible or difficult to purchase or sell. Although most of the fund's
securities and other investments must be liquid at the time of investment,
securities and other investments may become illiquid after purchase by the
fund, particularly


                                       27


More on the risks of investing in the fund

during periods of market turmoil. Markets may become illiquid when, for
instance, there are few, if any, interested buyers and sellers or when dealers
are unwilling to make a market for certain securities or when dealer
market-making capacity is otherwise reduced, and this is more likely to occur
as a result of the reduction of market support activity by the Federal Reserve.
A lack of liquidity or other adverse credit market conditions may affect the
fund's ability to sell the securities in which it invests or to find and
purchase suitable investments. These illiquid investments may also be difficult
to value. If the fund is forced to sell or unwind an illiquid investment to
meet redemption requests or for other cash needs, the fund may suffer a loss.
In addition, when there is illiquidity in the market for certain securities and
other investments, the fund, due to limitations on investments in illiquid
securities, may be unable to achieve its desired level of exposure to a certain
sector. Liquidity risk may be magnified in a rising interest rate environment
in which investor redemptions from fixed-income mutual funds may be higher than
normal. If an auction fails for an auction rate security, there may be no
secondary market for the security and the fund may be forced to hold the
security until the security is refinanced by the issuer or a secondary market
develops. To the extent the fund holds a material percentage of the outstanding
debt securities of an issuer, this practice may impact adversely the liquidity
and market value of those investments.

PORTFOLIO SELECTION RISK. The adviser's judgment about the quality, relative
yield, relative value or market trends affecting a particular sector or region,
market segment, security or about interest rates generally may prove to be
incorrect.

U.S. TREASURY OBLIGATIONS RISK. The market value of direct obligations of the
U.S. Treasury may vary due to changes in interest rates. In addition, changes
to the financial condition or credit rating of the U.S. government may cause
the value of the fund's investments in obligations issued by the U.S. Treasury
to decline.

U.S. GOVERNMENT AGENCY OBLIGATIONS RISK. The fund invests in obligations issued
by agencies and instrumentalities of the U.S. government. Government-sponsored
entities such as Federal National Mortgage Association ("FNMA"), Federal Home
Loan Mortgage Corporation ("FHLMC") and the Federal Home Loan Banks ("FHLBs"),
although chartered or sponsored by Congress, are not funded by congressional
appropriations and the debt and mortgage-backed securities issued by them are
neither guaranteed nor issued by the U.S. government. Such debt and
mortgage-backed securities


                                       28


are subject to the risk of default on the payment of interest and/or principal,
similar to debt of private issuers. Although the U.S. government has provided
financial support to FNMA and FHLMC in the past, there can be no assurance that
it will support these or other government-sponsored entities in the future.

MORTGAGE-RELATED AND ASSET-BACKED SECURITIES RISK. The repayment of certain
mortgage-backed and asset-backed securities depends primarily on the cash
collections received from the issuer's underlying asset portfolio and, in
certain cases, the issuer's ability to issue replacement securities. As a
result, there could be losses to the fund in the event of credit or market
value deterioration in the issuer's underlying portfolio, mismatches in the
timing of the cash flows of the underlying asset interests and the repayment
obligations of maturing securities, or the issuer's inability to issue new or
replacement securities. Mortgage-backed securities tend to be more sensitive to
changes in interest rate than other types of debt securities. These securities
are also subject to prepayment and extension risks. Upon the occurrence of
certain triggering events or defaults, the fund may become the holder of
underlying assets at a time when those assets may be difficult to sell or may
be sold only at a loss. In the event of a default, the value of the underlying
collateral may be insufficient to pay certain expenses, such as litigation and
foreclosure expenses, and inadequate to pay any principal or unpaid interest.
Privately issued mortgage-backed and asset-backed securities are not traded on
an exchange and may have a limited market. Without an active trading market,
these securities may be particularly difficult to value given the complexities
in valuing the underlying collateral.

Certain mortgage-backed and asset-backed securities may pay principal only at
maturity or may represent only the right to receive payments of principal or
interest on the underlying obligations, but not both. The value of these types
of instruments may change more drastically than debt securities that pay both
principal and interest during periods of changing interest rates. Principal
only instruments generally increase in value if interest rates decline, but are
also subject to the risk of prepayment. Interest only instruments generally
increase in value in a rising interest rate environment when fewer of the
underlying obligations are prepaid. Interest only instruments could lose their
entire value in a declining interest rate environment if the underlying
obligations are prepaid.

Unlike mortgage-related securities issued or guaranteed by the U.S. government
or its agencies and instrumentalities, mortgage-related securities issued by
private issuers do not have a government or government-sponsored


                                       29


More on the risks of investing in the fund

entity guarantee (but may have other credit enhancement), and may, and
frequently do, have less favorable collateral, credit risk or other
characteristics. The fund may invest in other mortgage-related securities,
including mortgage derivatives and structured securities. These securities
typically are not secured by real property. Because these securities have
embedded leverage features, small changes in interest or prepayment rates may
cause large and sudden price movements. These securities also can become
illiquid and difficult to value in volatile or declining markets.

Mortgage-backed securities are particularly susceptible to prepayment and
extension risks, because prepayments on the underlying mortgages tend to
increase when interest rates fall and decrease when interest rates rise.
Prepayments may also occur on a scheduled basis or due to foreclosure. When
market interest rates increase, mortgage refinancings and prepayments slow,
which lengthens the effective duration of these securities. As a result, the
negative effect of the interest rate increase on the market value of
mortgage-backed securities is usually more pronounced than it is for other
types of fixed income securities, potentially increasing the volatility of the
fund. Conversely, when market interest rates decline, while the value of
mortgage-backed securities may increase, the rates of prepayment of the
underlying mortgages tend to increase, which shortens the effective duration of
these securities. Mortgage-backed securities are also subject to the risk that
the underlying borrowers will be unable to meet their obligations.

At times, some of the mortgage-backed securities in which the fund may invest
will have higher than market interest rates and therefore will be purchased at
a premium above their par value. Prepayments may cause losses on securities
purchased at a premium.

The value of mortgage-backed and asset-backed securities may be affected by
changes in credit quality or value of the mortgage loans or other assets that
support the securities. In addition, for mortgage-backed securities, when
market conditions result in an increase in the default rates on the underlying
mortgages and the foreclosure values of the underlying real estate are below
the outstanding amount of the underlying mortgages, collection of the full
amount of accrued interest and principal on these investments may be less
likely.

The fund may invest in CMOs. Principal prepayments on the underlying mortgage
loans may cause a CMO to be retired substantially earlier than its stated
maturity or final distribution date. If there are defaults on the underlying
mortgage loans, the fund will be less likely to receive payments


                                       30


of principal and interest, and will be more likely to suffer a loss. This risk
may be increased to the extent the underlying mortgages include sub-prime
mortgages. As market conditions change, and particularly during periods of
rapid or unanticipated changes in market interest rates, the attractiveness of
a CMO class and the ability of the structure to provide the anticipated
investment characteristics may be significantly reduced. Such changes can
result in volatility in the market value, and in some instances reduced
liquidity, of a CMO class.

In response to the financial crisis that began in 2008, the Federal Reserve has
attempted to keep mortgage rates low by acting as a buyer of mortgage-backed
assets. This support has recently ended. As a result, mortgage rates may rise
and prices of mortgage-backed securities may fall. To the extent the fund's
assets are invested in mortgage-backed securities, returns to fund investors
may decline.

Asset-backed securities are structured like mortgage-backed securities and are
subject to many of the same risks. The ability of an issuer of asset-backed
securities to enforce its security interest in the underlying asset or to
otherwise recover from the underlying obligor may be limited. Certain
asset-backed securities present a heightened level of risk because, in the
event of default, the liquidation value of the underlying assets may be
inadequate to pay any unpaid principal or interest.

RISKS OF INSTRUMENTS THAT ALLOW FOR BALLOON PAYMENTS OR NEGATIVE AMORTIZATION
PAYMENTS. Certain debt instruments allow for balloon payments or negative
amortization payments. Such instruments permit the borrower to avoid paying
currently a portion of the interest accruing on the instrument. While these
features make the debt instrument more affordable to the borrower in the near
term, they increase the risk that the borrower will be unable to make the
resulting higher payment or payments that become due at the maturity of the
loan.

HIGH YIELD OR "JUNK" BOND RISK. Debt securities that are below investment
grade, called "junk bonds," are speculative, have a higher risk of default or
are already in default, tend to be less liquid and are more difficult to value
than higher grade securities and may involve major risk of exposure to adverse
conditions and negative sentiments. These securities have a higher risk of
issuer default because, among other reasons, issuers of junk bonds often have
more debt in relation to total capitalization than issuers of investment grade
securities. Junk bonds tend to be volatile and more susceptible to adverse
events and negative sentiments. These risks are


                                       31


More on the risks of investing in the fund

more pronounced for securities that are already in default. Changes in economic
conditions or developments regarding the individual issuer are more likely to
cause price volatility and weaken the capacity of such securities to make
principal and interest payments than is the case for higher grade debt
securities. The value of lower-quality debt securities often fluctuates in
response to company, political, or economic developments and can decline
significantly over short as well as long periods of time or during periods of
general or regional economic difficulty. Junk bonds may also be less liquid
than higher-rated securities, which means that the fund may have difficulty
selling them at times, and it may have to apply a greater degree of judgment in
establishing a price for purposes of valuing fund shares. Junk bonds generally
are issued by less creditworthy issuers. In the event of an issuer's
bankruptcy, claims of other creditors may have priority over the claims of junk
bond holders, leaving few or no assets available to repay junk bond holders.
The fund may incur expenses to the extent necessary to seek recovery upon
default or to negotiate new terms with a defaulting issuer. Junk bonds
frequently have redemption features that permit an issuer to repurchase the
security from the fund before it matures. If the issuer redeems junk bonds, the
fund may have to invest the proceeds in bonds with lower yields and may lose
income.

RISKS OF INVESTING IN FLOATING RATE LOANS. Floating rate loans and similar
investments may be illiquid or less liquid than other investments and difficult
to value. The value of collateral, if any, securing a floating rate loan can
decline or may be insufficient to meet the issuer's obligations or may be
difficult to liquidate. In the event of a default, the fund may have difficulty
collecting on any collateral and would not have the ability to collect on any
collateral for an uncollateralized loan. Further, the fund's access to
collateral, if any, may be limited by bankruptcy law. No active trading market
may exist for many floating rate loans, and many loans are subject to
restrictions on resale. Market quotations for these securities may be volatile
and/or subject to large spreads between bid and ask prices. Any secondary
market may be subject to irregular trading activity and extended trade
settlement periods. An economic downturn generally leads to a higher
non-payment rate, and a loan may lose significant value before a default
occurs. There is less readily available, reliable information about most
floating rate loans than is the case for many other types of securities.
Normally, Pioneer will seek to avoid receiving material, non-public information
about the issuer of a loan either held by, or considered for investment by, the
fund, and this decision could


                                       32


adversely affect the fund's investment performance. Loans may not be considered
"securities," and purchasers, such as the fund, therefore may not be entitled
to rely on the anti-fraud protections of the federal securities laws.

RISKS OF INVESTING IN INSURANCE-LINKED SECURITIES. The return of principal and
the payment of interest on "event-linked" bonds and other insurance-linked
securities are contingent on the non-occurrence of a pre-defined "trigger"
event, such as a hurricane or an earthquake of a specific magnitude or other
event that leads to physical or economic loss. If a trigger event, as defined
within the terms of an event-linked bond, involves losses or other metrics
exceeding a specific magnitude in the geographic region and time period
specified, the fund may lose a portion or all of its accrued interest and/or
principal invested in the event-linked bond. In addition to the specified
trigger events, event-linked bonds may expose the fund to other risks,
including but not limited to issuer (credit) default, adverse regulatory or
jurisdictional interpretations and adverse tax consequences. Event-linked bonds
are also subject to the risk that the model used to calculate the probability
of a trigger event was not accurate and underestimated the likelihood of a
trigger event. Insurance-linked securities may provide for extensions of
maturity in order to process and audit loss claims in those cases when a
trigger event has, or possibly has, occurred. Upon the occurrence or possible
occurrence of a trigger event, and until the completion of the processing and
auditing of applicable loss claims, the fund's investment in an event-linked
bond or other insurance-linked security may be priced using fair value methods.
Lack of a liquid market may impose the risk of higher transaction costs and the
possibility that the fund may be forced to liquidate positions when it would
not be advantageous to do so. Certain insurance-linked securities represent
interests in baskets of underlying reinsurance contracts. The fund has limited
transparency into the individual contracts underlying such securities and
therefore must rely on the risk assessment and sound underwriting practices of
the issuer. Certain insurance-linked securities may be difficult to value.

RISKS OF SUBORDINATED SECURITIES. A holder of securities that are subordinated
or "junior" to more senior securities of an issuer is entitled to payment after
holders of more senior securities of the issuer. Subordinated securities are
more likely to suffer a credit loss than non-subordinated securities of the
same issuer, any loss incurred by the subordinated securities is likely to be
proportionately greater, and any recovery of interest or principal may take
more time. If there is a default, bankruptcy or liquidation of the issuer, most
subordinated securities are paid only if sufficient assets remain after


                                       33


More on the risks of investing in the fund

payment of the issuer's non-subordinated securities. As a result, even a
perceived decline in creditworthiness of the issuer is likely to have a greater
impact on them.

MUNICIPAL SECURITIES RISK. The municipal bond market can be susceptible to
unusual volatility, particularly for lower-rated and unrated securities.
Liquidity can be reduced unpredictably in response to overall economic
conditions or credit tightening. Municipal issuers may be adversely affected by
rising health care costs, increasing unfunded pension liabilities and by the
phasing out of federal programs providing financial support. Unfavorable
conditions and developments relating to projects financed with municipal
securities can result in lower revenues to issuers of municipal securities,
potentially resulting in defaults. Issuers often depend on revenues from those
projects to make principal and interest payments. The value of municipal
securities can also be adversely affected by changes in the financial condition
of one or more individual municipal issuers or insurers of municipal issuers,
regulatory and political developments, tax law changes or other legislative
actions, and by uncertainties and public perceptions concerning these and other
factors. Municipal issuers may be more susceptible to downgrades or defaults
during recessions or similar periods of economic stress. In recent periods, an
increasing number of municipal issuers in the United States have defaulted on
obligations and commenced insolvency proceedings. Financial difficulties of
municipal issuers may continue or get worse. To the extent the fund invests
significantly in a single state or in securities the payments on which are
dependent upon a single project or source of revenues, or that relate to a
sector or industry, the fund will be more susceptible to associated risks and
developments.

RISKS OF ZERO COUPON BONDS, PAYMENT IN KIND, DEFERRED AND CONTINGENT PAYMENT
SECURITIES. Zero coupon bonds (which do not pay interest until maturity) and
payment in kind securities (which pay interest in the form of additional
securities) may be more speculative and may fluctuate more in value than
securities which pay income periodically and in cash. These securities are more
likely to respond to changes in interest rates than interest-bearing securities
having similar maturities and credit quality. These securities are more
sensitive to the credit quality of the underlying issuer. Payment in kind
securities may be difficult to value because their continuing accruals require
judgments about the collectability of the deferred payments and the value of
any collateral. Deferred interest securities are obligations that generally
provide for a period of delay before the regular payment of interest begins and
are issued at a significant discount from face value.


                                       34


The interest rate on contingent payment securities is determined by the outcome
of an event, such as the performance of a financial index. If the financial
index does not increase by a prescribed amount, the fund may receive no
interest.

Unlike bonds that pay interest throughout the period to maturity, the fund
generally will realize no cash until maturity and, if the issuer defaults, the
fund may obtain no return at all on its investment. In addition, although the
fund receives no periodic cash payments on such securities, the fund is deemed
for tax purposes to receive income from such securities, which applicable tax
rules require the fund to distribute to shareholders. Such distributions may be
taxable when distributed to shareholders and, in addition, could reduce the
fund's reserve position and require the fund to sell securities and incur a
gain or loss at a time it may not otherwise want in order to provide the cash
necessary for these distributions.

RISKS OF INVESTING IN "WHEN-ISSUED", DELAYED DELIVERY, TO BE ANNOUNCED AND
FORWARD COMMITMENT TRANSACTIONS. The market value of these transactions may
increase or decrease as a result of changes in interest rates. These
transactions involve risk of loss if the value of the underlying security
changes unfavorably before the settlement date or if the assets set aside to
pay for these securities decline in value prior to the settlement date.
Therefore, these transactions may have a leveraging effect on the fund, making
the value of an investment in the fund more volatile and increasing the fund's
overall investment exposure. There is also a risk that the security will not be
issued or that the other party to the transaction will default on its
obligation to purchase or sell the security, which may result in the fund
missing the opportunity to obtain a favorable price or yield elsewhere.

RISKS OF NON-U.S. INVESTMENTS. Investing in non-U.S. issuers, or in U.S.
issuers that have significant exposure to foreign markets, may involve unique
risks compared to investing in securities of U.S. issuers. These risks are more
pronounced for issuers in emerging markets or to the extent that the fund
invests significantly in one region or country. These risks may include:
o Less information about non-U.S. issuers or markets may be available due to
  less rigorous disclosure or accounting standards or regulatory practices
o Many non-U.S. markets are smaller, less liquid and more volatile. In a
  changing market, the adviser may not be able to sell the fund's portfolio
  securities at times, in amounts and at prices it considers reasonable


                                       35


More on the risks of investing in the fund

o Adverse effect of currency exchange rates or controls on the value of the
  fund's investments, or its ability to convert non-U.S. currencies to U.S.
  dollars
o The economies of non-U.S. countries may grow at slower rates than expected or
  may experience a downturn or recession
o Economic, political, regulatory and social developments may adversely affect
  the securities markets
o It may be difficult for the fund to pursue claims or enforce judgments
  against a foreign bank, depository or issuer of a security, or any of their
  agents, in the courts of a foreign country
o Withholding and other non-U.S. taxes may decrease the fund's return. The
  value of the fund's foreign investments also may be affected by U.S. tax
  considerations and restrictions in receiving investment proceeds from a
  foreign country
o Some markets in which the fund may invest are located in parts of the world
  that have historically been prone to natural disasters that could result in
  a significant adverse impact on the economies of those countries and
  investments made in those countries
o It is often more expensive for the fund to buy, sell and hold securities in
  certain foreign markets than in the United States
o A governmental entity may delay, or refuse or be unable to pay, interest or
  principal on its sovereign debt due to cash flow problems, insufficient
  foreign currency reserves, political considerations, the relative size of
  the governmental entity's debt position in relation to the economy or the
  failure to put in place economic reforms
o Investing in depositary receipts is subject to many of the same risks as
  investing directly in non-U.S. issuers. Depositary receipts may involve
  higher expenses and may trade at a discount (or premium) to the underlying
  security. In addition, depositary receipts may not pass through voting and
  other shareholder rights, and may be less liquid than the underlying
  securities listed on an exchange.
o A number of countries in the European Union (EU) have experienced, and may
  continue to experience, severe economic and financial difficulties.
  Additional EU member countries may also fall subject to such difficulties.
  These events could negatively affect the value and liquidity of the fund's
  investments in euro-denominated securities and derivative contracts,
  securities of issuers located in the EU or with significant exposure to EU
  issuers or countries
o If one or more stockholders of a supranational entity such as the World Bank
  fail to make necessary additional capital contributions, the entity may be
  unable to pay interest or repay principal on its debt securities


                                       36


RISKS OF CONVERTIBLE SECURITIES. Convertible securities generally offer lower
interest or dividend yields than non-convertible securities of similar quality.
As with all fixed income securities, the market values of convertible
securities tend to decline as interest rates increase and, conversely, to
increase as interest rates decline. However, when the market price of the
common stock underlying a convertible security approaches or exceeds the
conversion price, the convertible security tends to reflect the market price of
the underlying common stock. As the market price of the underlying common stock
declines, the convertible security tends to trade increasingly on a yield basis
and thus may not decline in price to the same extent as the underlying common
stock. Convertible securities rank senior to common stocks in an issuer's
capital structure and consequently entail less risk than the issuer's common
stock. The value of a synthetic convertible security will respond differently
to market fluctuations than a traditional convertible security because a
synthetic convertible security is composed of two or more separate securities
or instruments, each with its own market value. If the value of the underlying
common stock or the level of the index involved in the convertible component
falls below the exercise price of the warrant or option, the warrant or option
may lose all value.

PREFERRED STOCKS RISK. Preferred stocks may pay fixed or adjustable rates of
return. Preferred stocks are subject to issuer-specific and market risks
applicable generally to equity securities. In addition, a company's preferred
stocks generally pay dividends only after the company makes required payments
to holders of its bonds and other debt. Thus, the value of preferred stocks
will usually react more strongly than bonds and other debt to actual or
perceived changes in the company's financial condition or prospects. The market
value of preferred stocks generally decreases when interest rates rise.
Preferred stocks of smaller companies may be more vulnerable to adverse
developments than preferred stocks of larger companies.

DERIVATIVES RISK. Using swaps, futures and other derivatives exposes the fund
to special risks and costs and may result in losses to the fund, even when used
for hedging purposes. Using derivatives can increase losses and reduce
opportunities for gain when market prices, interest rates or currencies, or the
derivative instruments themselves, behave in a way not anticipated by the fund,
especially in abnormal market conditions. Using derivatives can have a
leveraging effect (which may increase investment losses) and increase the
fund's volatility, which is the degree to which the fund's share price may
fluctuate within a short time period. Certain derivatives have the potential
for unlimited loss, regardless of the size of the fund's


                                       37


More on the risks of investing in the fund

initial investment. If changes in a derivative's value do not correspond to
changes in the value of the fund's other investments or do not correlate well
with the underlying assets, rate or index, the fund may not fully benefit from,
or could lose money on, or could experience unusually high expenses as a result
of, the derivative position. The other parties to certain derivative
transactions present the same types of credit risk as issuers of fixed income
securities. Derivatives also tend to involve greater liquidity risk and they
may be difficult to value. The fund may be unable to terminate or sell its
derivative positions. In fact, many over-the-counter derivatives will not have
liquidity beyond the counterparty to the instrument. Use of derivatives or
similar instruments may have different tax consequences for the fund than an
investment in the underlying security, and those differences may affect the
amount, timing and character of income distributed to shareholders. The fund's
use of derivatives may also increase the amount of taxes payable by
shareholders. Risks associated with the use of derivatives are magnified to the
extent that an increased portion of the fund's assets are committed to
derivatives in general or are invested in just one or a few types of
derivatives.

Investments by the fund in structured securities, a type of derivative, raise
certain tax, legal, regulatory and accounting issues that may not be presented
by direct investments in securities. These issues could be resolved in a manner
that could hurt the performance of the fund.

Swap agreements and options to enter into swap agreements ("swaptions") tend to
shift the fund's investment exposure from one type of investment to another.
For example, the fund may enter into interest rate swaps, which involve the
exchange of interest payments by the fund with another party, such as the
exchange of floating rate payments for fixed interest payments with respect to
a notional amount of principal. If an interest rate swap intended to be used as
a hedge negates a favorable interest rate movement, the investment performance
of the fund would be less than it would have been if the fund had not entered
into the interest rate swap.

The U.S. government and foreign governments are in the process of adopting and
implementing regulations governing derivative markets, including mandatory
clearing of certain derivatives, margin and reporting requirements. The
ultimate impact of the regulations remains unclear. Additional regulation of
derivatives may make derivatives more costly, may limit their availability or
utility or otherwise adversely affect their performance, or may disrupt


                                       38


markets. The fund may be exposed to additional risks as a result of the
additional regulations. The extent and impact of the regulations are not yet
fully known and may not be for some time.

The fund will be required to maintain its positions with a clearing
organization through one or more clearing brokers. The clearing organization
will require the fund to post margin and the broker may require the fund to
post additional margin to secure the fund's obligations. The amount of margin
required may change from time to time. In addition, cleared transactions may be
more expensive to maintain than over-the-counter transactions and may require
the fund to deposit larger amounts of margin. The fund may not be able to
recover margin amounts if the broker has financial difficulties. Also, the
broker may require the fund to terminate a derivatives position under certain
circumstances. This may cause the fund to lose money. The fund's ability to use
certain derivative instruments currently is limited by Commodity Futures
Trading Commission rules.

CREDIT DEFAULT SWAP RISK. Credit default swap contracts, a type of derivative
instrument, involve heightened risks and may result in losses to the fund.
Credit default swaps may in some cases be illiquid and difficult to value, and
they increase credit risk since the fund has exposure to both the issuer of the
referenced obligation and the counterparty to the credit default swap. If the
fund buys a credit default swap, it will be subject to the risk that the credit
default swap may expire worthless, as the credit default swap would only
generate income in the event of a default on the underlying debt security or
other specified event. As a buyer, the fund would also be subject to credit
risk relating to the seller's payment of its obligations in the event of a
default (or similar event). If the fund sells a credit default swap, it will be
exposed to the credit risk of the issuer of the obligation to which the credit
default swap relates. As a seller, the fund would also be subject to leverage
risk, because it would be liable for the full notional amount of the swap in
the event of default (or similar event). Swaps may be difficult to unwind or
terminate. Certain index-based credit default swaps are structured in tranches,
whereby junior tranches assume greater default risk than senior tranches. The
absence of a central exchange or market for swap transactions may lead, in some
instances, to difficulties in trading and valuation, especially in the event of
market disruptions. New regulations require many kinds of swaps to be executed
through a centralized exchange or regulated facility and be cleared through a
regulated clearinghouse. Although this clearing mechanism is generally expected
to reduce counterparty credit risk, it may disrupt or limit the swap market and
may not result in swaps being easier


                                       39


More on the risks of investing in the fund

to trade or value. As swaps become more standardized, the fund may not be able
to enter into swaps that meet its investment needs. The fund also may not be
able to find a clearinghouse willing to accept the swaps for clearing. In a
cleared swap, a central clearing organization will be the counterparty to the
transaction. The fund will assume the risk that the clearinghouse may be unable
to perform its obligations. The new regulations may make using swaps more
costly, may limit their availability, or may otherwise adversely affect their
value or performance.

RISKS OF INVESTING IN INVERSE FLOATING RATE OBLIGATIONS. The interest rate on
inverse floating rate obligations will generally decrease as short-term
interest rates increase, and increase as short-term rates decrease. Due to
their leveraged structure, the sensitivity of the market value of an inverse
floating rate obligation to changes in interest rates is generally greater than
a comparable long-term bond issued by the same issuer and with similar credit
quality, redemption and maturity provisions. Inverse floating rate obligations
may be volatile and involve leverage risk.

LEVERAGING RISK. The value of your investment may be more volatile and other
risks tend to be compounded if the fund borrows or uses derivatives or other
investments that have embedded leverage. Leverage generally magnifies the
effect of any increase or decrease in the value of the fund's underlying assets
and creates a risk of loss of value on a larger pool of assets than the fund
would otherwise have, potentially resulting in the loss of all assets. Engaging
in such transactions may cause the fund to liquidate positions when it may not
be advantageous to do so to satisfy its obligations or meet segregation
requirements.

REPURCHASE AGREEMENT RISK. In the event that the other party to a repurchase
agreement defaults on its obligations, the fund may encounter delay and incur
costs before being able to sell the security. Such a delay may involve loss of
interest or a decline in price of the security. In addition, if the fund is
characterized by a court as an unsecured creditor, it would be at risk of
losing some or all of the principal and interest involved in the transaction.

MARKET SEGMENT RISK. To the extent the fund emphasizes, from time to time,
investments in a market segment, the fund will be subject to a greater degree
to the risks particular to that segment, and may experience greater market
fluctuation, than a fund without the same focus. For example, industries in the
financial segment, such as banks, insurance companies,


                                       40


broker-dealers and real estate investment trusts (REITs), may be sensitive to
changes in interest rates and general economic activity and are generally
subject to extensive government regulation.

VALUATION RISK. Many factors may influence the price at which the fund could
sell any particular portfolio investment. The sales price may well differ -
higher or lower - from the fund's last valuation of the investment, and such
differences could be significant, particularly for illiquid securities and
securities that trade in thin markets and/or markets that experience extreme
volatility. If market conditions make it difficult to value some investments,
the fund may value these investments using more subjective methods. Investors
who purchase or redeem fund shares on days when the fund is holding fair-valued
securities may receive fewer or more shares or lower or higher redemption
proceeds than they would have received if the fund had not fair-valued the
security or had used a different valuation methodology. Fixed income securities
are typically valued using fair value methodologies. The value of foreign
securities, certain fixed income securities and currencies, as applicable, may
be materially affected by events after the close of the market on which they
are valued, but before the fund determines its net asset value.

CASH MANAGEMENT RISK. The value of the investments held by the fund for cash
management or temporary defensive purposes may be affected by market risks,
changing interest rates and by changes in credit ratings of the investments. To
the extent that the fund has any uninvested cash, the fund would be subject to
credit risk with respect to the depository institution holding the cash. If the
fund holds cash uninvested, the fund will not earn income on the cash and the
fund's yield will go down. During such periods, it may be more difficult for
the fund to achieve its investment objectives.

EXPENSE RISK. Your actual costs of investing in the fund may be higher than the
expenses shown in "Annual fund operating expenses" for a variety of reasons.
For example, expense ratios may be higher than those shown if overall net
assets decrease. Net assets are more likely to decrease and fund expense ratios
are more likely to increase when markets are volatile.

To learn more about the fund's investments and risks, you should obtain and
read the statement of additional information. Please note that there are many
other factors that could adversely affect your investment and that could
prevent the fund from achieving its goals.

Management

INVESTMENT ADVISER
Pioneer, the fund's investment adviser, selects the fund's investments and
oversees the fund's operations.

Pioneer is an indirect, wholly owned subsidiary of UniCredit S.p.A., one of the
largest banking groups in Italy. Pioneer is part of the global asset management
group providing investment management and financial services to mutual funds,
institutional and other clients. As of September 30, 2015, assets under
management were approximately $243 billion worldwide, including over $66
billion in assets under management by Pioneer (and its U.S. affiliates).

Pioneer's main office is at 60 State Street, Boston, Massachusetts 02109.

The firm's U.S. mutual fund investment history includes creating in 1928 one of
the first mutual funds.

Pioneer has received an order from the Securities and Exchange Commission that
permits Pioneer, subject to the approval of the fund's Board of Trustees, to
hire and terminate a subadviser that is not affiliated with Pioneer (an
"unaffiliated subadviser") or to materially modify an existing subadvisory
contract with an unaffiliated subadviser for the fund without shareholder
approval. Pioneer retains the ultimate responsibility to oversee and recommend
the hiring, termination and replacement of any unaffiliated subadviser.


PORTFOLIO MANAGEMENT
Day-to-day management of the fund's portfolio is the responsibility of Kenneth
J. Taubes. Mr. Taubes is supported by Charles Melchreit. Mr. Taubes and Mr.
Melchreit are supported by the fixed income team. Members of this team manage
other Pioneer funds investing primarily in fixed income securities. The

Pricing of shares

NET ASSET VALUE
The fund's net asset value is the value of its securities plus any other assets
minus its accrued operating expenses and other liabilities. The fund calculates
a net asset value for each class of shares every day the New York Stock
Exchange is open as of the scheduled close of regular trading (normally 4:00
p.m. Eastern time). If the New York Stock Exchange closes at another time, the
fund will calculate a net asset value for each class of shares as of the
scheduled closing time. On days when the New York Stock Exchange is closed for
trading, including certain holidays listed in the statement of additional
information, a net asset value is not calculated. The fund's most recent net
asset value is available on the fund's website, us.pioneerinvestments.com.

The fund generally values debt securities and certain derivative instruments by
using the prices supplied by independent third party pricing services. A
pricing service may use market prices or quotations from one or more brokers or
other sources, or may use a pricing matrix or other fair value methods or
techniques to provide an estimated value of the security or instrument. A
pricing matrix is a means of valuing a debt security on the basis of current
market prices for other debt securities, historical trading patterns in the
market for fixed income securities and/or other factors. Non-U.S. debt
securities that are listed on an exchange will be valued at the bid price
obtained from an independent third party pricing service.

Senior loans are valued at the mean between the last available bid and asked
prices for one or more brokers or dealers as obtained from an independent third
party pricing service. If no reliable prices are available from either the
primary or an alternative pricing service, broker quotes will be solicited.
Event linked bonds are valued at the bid price obtained from an independent
third party pricing service. Other insurance-linked securities may be valued at
the bid price obtained from an independent third party pricing service, or
through a third party using a pricing matrix, insurance industry valuation
models, or other fair value methods or techniques to provide an estimated value
of the instrument.

The fund generally values its equity securities and certain derivative
instruments that are traded on an exchange using the last sale price on the
principal exchange on which they are traded. Equity securities that are not
traded on the date of valuation, or securities for which no last sale prices
are available, are valued at the mean between the last bid and asked prices or,
if both last bid and asked prices are not available, at the last quoted bid
price.


                                       45


Pricing of shares

Last sale, bid and asked prices are provided by independent third party pricing
services. In the case of equity securities not traded on an exchange, prices
are typically determined by independent third party pricing services approved
by the Board of Trustees using a variety of techniques and methods. The fund
may use a fair value model developed by an independent pricing service to value
non-U.S. equity securities.

To the extent that the fund invests in shares of other mutual funds that are
not traded on an exchange, such shares of other mutual funds are valued at
their net asset values as provided by those funds. The prospectuses for those
funds explain the circumstances under which those funds will use fair value
pricing methods and the effects of using fair value pricing methods.

The valuations of securities traded in non-U.S. markets and certain fixed
income securities will generally be determined as of the earlier closing time
of the markets on which they primarily trade. When the fund holds securities or
other assets that are denominated in a foreign currency, the fund will normally
use the currency exchange rates as of 3:00 p.m. (Eastern time). Non-U.S.
markets are open for trading on weekends and other days when the fund does not
price its shares. Therefore, the value of the fund's shares may change on days
when you will not be able to purchase or redeem fund shares.

When independent third party pricing services are unable to supply prices for
an investment, or when prices or market quotations are considered by Pioneer to
be unreliable, the value of that security may be determined using quotations
from one or more broker-dealers. When such prices or quotations are not
available, or when they are considered by Pioneer to be unreliable, the fund
uses fair value methods to value its securities pursuant to procedures adopted
by the Board of Trustees. The fund also may use fair value methods if it is
determined that a significant event has occurred between the time at which a
price is determined and the time at which the fund's net asset value is
calculated. Because the fund may invest in securities rated below investment
grade - some of which may be thinly traded and for which prices may not be
readily available or may be unreliable - the fund may use fair value methods
more frequently than funds that primarily invest in securities that are more
widely traded. Valuing securities using fair value methods may cause the net
asset value of the fund's shares to differ from the net asset value that would
be calculated only using market prices.


                                       46


The prices used by the fund to value its securities may differ from the amounts
that would be realized if these securities were sold and these differences may
be significant, particularly for securities that trade in relatively thin
markets and/or markets that experience extreme volatility.


                                       47


Choosing a class of shares

The fund offers five classes of shares through this prospectus. Each class has
different eligibility requirements, sales charges and expenses, allowing you to
choose the class that best meets your needs.

Factors you should consider include:
o The eligibility requirements that apply to purchases of a particular share
  class
o The expenses paid by each class
o The initial sales charges and contingent deferred sales charges (CDSCs), if
  any, applicable to each class
o Whether you qualify for any reduction or waiver of sales charges
o How long you expect to own the shares
o Any services you may receive from a financial intermediary

Your investment professional can help you determine which class meets your
goals. Your investment professional or financial intermediary may receive
different compensation depending upon which class you choose. If you are not a
U.S. citizen and are purchasing shares outside the U.S., you may pay different
sales charges under local laws and business practices.

For information on the fund's expenses, please see "Fund Summary."

its affiliates, certain direct investors, other Pioneer funds, and certain
tax-deferred retirement plans (including 401(k) plans, employer-sponsored

                                       50


Distribution and service arrangements

DISTRIBUTION PLAN
The fund has adopted a distribution plan for Class A, Class C and Class R
shares in accordance with Rule 12b-1 under the Investment Company Act of 1940.
Under the plan, the fund pays distribution and service fees to the distributor.
Because these fees are an ongoing expense of the fund, over time they increase
the cost of your investment and your shares may cost more than shares that are
subject to other types of sales charges.


CLASS R SHARES SERVICE PLAN
The fund has adopted a separate service plan for Class R shares. Under the
service plan, the fund may pay securities dealers, plan administrators or other
financial intermediaries who agree to provide certain services to plans or plan
participants holding shares of the fund a service fee of up to 0.25% of average
daily net assets attributable to Class R shares held by such plan participants.
The services provided under the service plan include acting as a shareholder of
record, processing purchase and redemption orders, maintaining participant
account records and answering participant questions regarding the fund.


ADDITIONAL PAYMENTS TO FINANCIAL INTERMEDIARIES
Your financial intermediary may receive compensation from the fund, Pioneer and
its affiliates for the sale of fund shares and related services. Compensation
may include sales commissions and distribution and service (Rule 12b-1) fees,
as well as compensation for administrative services and transaction processing.

Pioneer and its affiliates may make additional payments to your financial
intermediary. These payments may provide your financial intermediary with an
incentive to favor the Pioneer funds over other mutual funds or assist the
distributor in its efforts to promote the sale of the fund's shares. Financial
intermediaries include broker-dealers, banks (including bank trust
departments), registered investment advisers, financial planners, retirement
plan administrators and other types of intermediaries.

Pioneer makes these additional payments (sometimes referred to as "revenue
sharing") to financial intermediaries out of its own assets, which may include
profits derived from services provided to the fund, or from the retention of a
portion of sales charges or distribution and service fees. Pioneer may


                                       51


Distribution and service arrangements

base these payments on a variety of criteria, including the amount of sales or
assets of the Pioneer funds attributable to the financial intermediary or as a
per transaction fee.

Not all financial intermediaries receive additional compensation and the amount
of compensation paid varies for each financial intermediary. In certain cases,
these payments may be significant. Pioneer determines which firms to support
and the extent of the payments it is willing to make, generally choosing firms
that have a strong capability to effectively distribute shares of the Pioneer
funds and that are willing to cooperate with Pioneer's promotional efforts.
Pioneer also may compensate financial intermediaries (in addition to amounts
that may be paid by the fund) for providing certain administrative services and
transaction processing services.

Pioneer may benefit from revenue sharing if the intermediary features the
Pioneer funds in its sales system (such as by placing certain Pioneer funds on
its preferred fund list or giving access on a preferential basis to members of
the financial intermediary's sales force or management). In addition, the
financial intermediary may agree to participate in the distributor's marketing
efforts (such as by helping to facilitate or provide financial assistance for
conferences, seminars or other programs at which Pioneer personnel may make
presentations on the Pioneer funds to the intermediary's sales force). To the
extent intermediaries sell more shares of the Pioneer funds or retain shares of
the Pioneer funds in their clients' accounts, Pioneer receives greater
management and other fees due to the increase in the Pioneer funds' assets. The
intermediary may earn a profit on these payments if the amount of the payment
to the intermediary exceeds the intermediary's costs.

The compensation that Pioneer pays to financial intermediaries is discussed in
more detail in the fund's statement of additional information. Your
intermediary may charge you additional fees or commissions other than those
disclosed in this prospectus. Intermediaries may categorize and disclose these
arrangements differently than in the discussion above and in the statement of
additional information. You can ask your financial intermediary about any
payments it receives from Pioneer or the Pioneer funds, as well as about fees
and/or commissions it charges.

Pioneer and its affiliates may have other relationships with your financial
intermediary relating to the provision of services to the Pioneer funds, such
as providing omnibus account services or effecting portfolio transactions for
the Pioneer funds. If your intermediary provides these services, Pioneer


                                       52


or the Pioneer funds may compensate the intermediary for these services. In
addition, your intermediary may have other relationships with Pioneer or its
affiliates that are not related to the Pioneer funds.


                                       53


Sales charges

INITIAL SALES CHARGES (CLASS A SHARES ONLY)
You pay the offering price (the net asset value per share plus any initial
sales charge) when you buy Class A shares unless you qualify to purchase shares
at net asset value. You pay a lower sales charge as the size of your investment
increases. You do not pay a sales charge when you reinvest dividends or capital
gain distributions paid by the fund.

The dollar amount of the sales charge is the difference between the offering
price of the shares purchased (based on the applicable sales charge in the
table) and the net asset value of those shares. Since the offering price is
calculated to two decimal places using standard rounding methodology, the
dollar amount of the sales charge as a percentage of the offering price and of
the net amount invested for any particular purchase of fund shares may be
higher or lower due to rounding.


REDUCED SALES CHARGES
You may qualify for a reduced Class A sales charge if you own or are purchasing
shares of Pioneer mutual funds. The investment levels required to obtain a
reduced sales charge are commonly referred to as "breakpoints." Pioneer offers
two principal means of taking advantage of breakpoints in sales charges for
aggregate purchases of Class A shares of the Pioneer funds over time if:
o The amount of shares you own of the Pioneer funds plus the amount you are
  investing now is at least $100,000 (Rights of accumulation)
o You plan to invest at least $100,000 over the next 13 months (Letter of
  intent)


RIGHTS OF ACCUMULATION
If you qualify for rights of accumulation, your sales charge will be based on
the combined value (at the current offering price) of all your Pioneer mutual
fund shares, the shares of your spouse and the shares of any children under the
age of 21.


                                       54


LETTER OF INTENT
You can use a letter of intent to qualify for reduced sales charges in
two situations:
o If you plan to invest at least $100,000 (excluding any reinvestment of
  dividends and capital gain distributions) in the fund's Class A shares
  during the next 13 months
o If you include in your letter of intent the value (at the current offering
  price) of all of your Class A shares of the fund and Class A or Class C
  shares of all other Pioneer mutual fund shares held of record in the amount
  used to determine the applicable sales charge for the fund shares you plan
  to buy

Completing a letter of intent does not obligate you to purchase additional
shares, but if you do not buy enough shares to qualify for the projected level
of sales charges by the end of the 13-month period (or when you sell your
shares, if earlier), the distributor will recalculate your sales charge. You
must pay the additional sales charge within 20 days after you are notified of
the recalculation or it will be deducted from your account (or your sale
proceeds). Any share class for which no sales charge is paid cannot be included
under the letter of intent. For more information regarding letters of intent,
please contact your investment professional or obtain and read the statement of
additional information.


QUALIFYING FOR A REDUCED CLASS A SALES CHARGE
In calculating your total account value in order to determine whether you have
met sales charge breakpoints, you can include your Pioneer mutual fund shares,
those of your spouse and the shares of any children under the age of 21.
Pioneer will use each fund's current offering price to calculate your total
account value. Certain trustees and fiduciaries may also qualify for a reduced
sales charge.

To receive a reduced sales charge, you or your investment professional must, at
the time of purchase, notify the distributor of your eligibility. In order to
verify your eligibility for a discount, you may need to provide your investment
professional or the fund with information or records, such as account numbers
or statements, regarding shares of the fund or other Pioneer mutual funds held
in all accounts by you, your spouse or children under the age of 21 with that
investment professional or with any other financial intermediary. Eligible
accounts may include joint accounts, retirement plan accounts, such as IRA and
401k accounts, and custodial accounts, such as ESA, UGMA and UTMA accounts.


                                       55


Sales charges

It is your responsibility to confirm that your investment professional has
notified the distributor of your eligibility for a reduced sales charge at the
time of sale. If you or your investment professional do not notify the
distributor of your eligibility, you will risk losing the benefits of a reduced
sales charge.

For this purpose, Pioneer mutual funds include any fund for which the
distributor is principal underwriter and, at the distributor's discretion, may
include funds organized outside the U.S. and managed by Pioneer or an
affiliate.

You can locate information regarding the reduction or waiver of sales charges,
in a clear and prominent format and free of charge, on Pioneer's website at
us.pioneerinvestments.com. The website includes hyperlinks that facilitate
access to this information.


CLASS A PURCHASES AT NET ASSET VALUE
You may purchase Class A shares at net asset value (without a sales charge) as
follows. If you believe you qualify for any of the Class A sales charge waivers
discussed below, contact your investment professional or the distributor. You
are required to provide written confirmation of your eligibility. You may not
resell these shares except to or on behalf of the fund.


CLASS A PURCHASES AT NET ASSET VALUE ARE AVAILABLE TO:
o Current or former trustees and officers of the fund;
o Partners and employees of legal counsel to the fund (at the time of initial
  share purchase);
o Directors, officers, employees or sales representatives of Pioneer and its
  affiliates (at the time of initial share purchase);
o Directors, officers, employees or sales representatives of any subadviser or
  a predecessor adviser (or their affiliates) to any investment company for
  which Pioneer serves as investment adviser (at the time of initial share
  purchase);


                                       56


o Officers, partners, employees or registered representatives of broker-dealers
  (at the time of initial share purchase) which have entered into sales
  agreements with the distributor;

  or other financial intermediaries adhering to standards established by the
  distributor;

o Investors in connection with certain reorganization, liquidation or
  acquisition transactions involving other investment companies or personal
  holding companies;
o Certain unit investment trusts;
o Group employer-sponsored retirement plans with at least $500,000 in total
  plan assets. Waivers for group employer-sponsored retirement plans do not
  apply to traditional IRAs, Roth IRAs, SEPs, SARSEPs, SIMPLE IRAs, KEOGHs,
  individual 401(k) or individual 403(b) plans, or to brokerage relationships
  in which sales charges are customarily imposed;
o Group employer-sponsored retirement plans with accounts established with
  Pioneer on or before March 31, 2004 with 100 or more eligible employees or
  at least $500,000 in total plan assets;
o Participants in an employer-sponsored 403(b) plan or employer-sponsored 457
  plan if (i) your employer has made special arrangements for your plan to
  operate as a group through a single broker, dealer or financial intermediary
  and (ii) all participants in the plan who purchase shares of a Pioneer
  mutual fund do so through a single broker, dealer or other financial
  intermediary designated by your employer;
o Investors purchasing shares pursuant to the reinstatement privilege
  applicable to Class A shares; and
o Shareholders of record (i.e., shareholders whose shares are not held in the
  name of a broker or an omnibus account) on the date of the reorganization of
  a predecessor Safeco fund into a corresponding Pioneer fund, shareholders
  who owned shares in the name of an omnibus account provider on that

Sales charges

  date that agrees with the fund to distinguish beneficial holders in the same
  manner, and retirement plans with assets invested in the predecessor Safeco
  fund on that date.

In addition, Class A shares may be purchased at net asset value through certain
mutual fund programs sponsored by qualified intermediaries, such as
broker-dealers and investment advisers. In each case, the intermediary has
entered into an agreement with Pioneer to include the Pioneer funds in their
program without the imposition of a sales charge. The intermediary provides
investors participating in the program with additional services, including
advisory, asset allocation, recordkeeping or other services. You should ask
your investment firm if it offers and you are eligible to participate in such a
mutual fund program and whether participation in the program is consistent with
your investment goals. The intermediaries sponsoring or participating in these
mutual fund programs also may offer their clients other classes of shares of
the funds and investors may receive different levels of services or pay
different fees depending upon the class of shares included in the program.
Investors should consider carefully any separate transaction and other fees
charged by these programs in connection with investing in each available share
class before selecting a share class. Such mutual fund programs include certain
self-directed brokerage services accounts held through qualified intermediaries
that may or may not charge participating investors transaction fees.


CONTINGENT DEFERRED SALES CHARGES (CDSCS)


CLASS A SHARES
Purchases of Class A shares of $500,000 or more may be subject to a contingent
deferred sales charge upon redemption. A contingent deferred sales charge is
payable to the distributor in the event of a share redemption within 12 months
following the share purchase at the rate of 1% of the lesser of the value of
the shares redeemed (exclusive of reinvested dividend and capital gain
distributions) or the total cost of such shares. However, the contingent
deferred sales charge is waived for redemptions of Class A shares purchased by
an employer-sponsored retirement plan that has at least $500,000 in total plan
assets (or that has 1,000 or more eligible employees for plans with accounts
established with Pioneer on or before March 31, 2004).


                                       58


CLASS C SHARES
You buy Class C shares at net asset value per share without paying an initial
sales charge. However, if you sell your Class C shares within one year of
purchase, upon redemption you will pay the distributor a contingent deferred
sales charge of 1% of the current market value or the original cost of the
shares you are selling, whichever is less.


PAYING THE CONTINGENT DEFERRED SALES CHARGE (CDSC)
Several rules apply for calculating CDSCs so that you pay the lowest possible
CDSC.
o The CDSC is calculated on the current market value or the original cost of
  the shares you are selling, whichever is less
o You do not pay a CDSC on reinvested dividends or distributions
o If you sell only some of your shares, the transfer agent will first sell your
  shares that are not subject to any CDSC and then the shares that you have
  owned the longest
o You may qualify for a waiver of the CDSC normally charged. See "Waiver or
  reduction of contingent deferred sales charges"


WAIVER OR REDUCTION OF CONTINGENT DEFERRED SALES CHARGES
It is your responsibility to confirm that your investment professional has
notified the distributor of your eligibility for a reduced sales charge at the
time of sale. If you or your investment professional do not notify the
distributor of your eligibility, you will risk losing the benefits of a reduced
sales charge.

The distributor may waive or reduce the CDSC for Class A shares that are
subject to a CDSC or for Class C shares if:
o The distribution results from the death of all registered account owners or a
  participant in an employer-sponsored plan. For UGMAs, UTMAs and trust
  accounts, the waiver applies only upon the death of all beneficial owners;
o You become disabled (within the meaning of Section 72 of the Internal Revenue
  Code) after the purchase of the shares being sold. For UGMAs, UTMAs and
  trust accounts, the waiver only applies upon the disability of all
  beneficial owners;
o The distribution is made in connection with limited automatic redemptions as
  described in "Systematic withdrawal plans" (limited in any year to 10% of
  the value of the account in the fund at the time the withdrawal plan is
  established);
o The distribution is from any type of IRA, 403(b) or employer-sponsored plan
  described under Section 401(a) or 457 of the Internal Revenue Code and, in
  connection with the distribution, one of the following applies:


                                       59


Sales charges

  - It is part of a series of substantially equal periodic payments made over
    the life expectancy of the participant or the joint life expectancy of the
    participant and his or her beneficiary (limited in any year to 10% of the
    value of the participant's account at the time the distribution amount is
    established);
  - It is a required minimum distribution due to the attainment of age 70 1/2,
    in which case the distribution amount may exceed 10% (based solely on
    total plan assets held in Pioneer mutual funds);
  - It is rolled over to or reinvested in another Pioneer mutual fund in the
    same class of shares, which will be subject to the CDSC of the shares
    originally held; or
  - It is in the form of a loan to a participant in a plan that permits loans
    (each repayment applied to the purchase of shares will be subject to a
    CDSC as though a new purchase);
o The distribution is to a participant in an employer-sponsored retirement plan
  described under Section 401(a) of the Internal Revenue Code or to a
  participant in an employer-sponsored 403(b) plan or employer-sponsored 457
  plan if (i) your employer has made special arrangements for your plan to
  operate as a group through a single broker, dealer or financial intermediary
  and (ii) all participants in the plan who purchase shares of a Pioneer
  mutual fund do so through a single broker, dealer or other financial
  intermediary designated by your employer and is or is in connection with:
  - A return of excess employee deferrals or contributions;
  - A qualifying hardship distribution as described in the Internal Revenue
    Code;
  - Due to retirement or termination of employment;
  - From a qualified defined contribution plan and represents a participant's
    directed transfer, provided that this privilege has been preauthorized
    through a prior agreement with the distributor regarding participant
    directed transfers;
o The distribution is made pursuant to the fund's right to liquidate or
  involuntarily redeem shares in a shareholder's account;
o The distribution is made to pay an account's advisory or custodial fees; or
o The distributor does not pay the selling broker a commission normally paid at
  the time of the sale.

Please see the fund's statement of additional information for more information
regarding reduced sales charges and breakpoints.

determined as of the scheduled close of regular trading on the New York Stock
Exchange on that day (plus or minus any applicable sales charges). If your
order is received by the transfer agent or an authorized agent after the
scheduled close of regular trading on the New York Stock Exchange, or your
order is not in good order, the share price will be based on the net asset
value next determined after your order is received in good order by the fund or
authorized agent. The authorized agent is responsible for transmitting your
order to the fund in a timely manner.


GOOD ORDER MEANS THAT:
o You have provided adequate instructions
o There are no outstanding claims against your account
o There are no transaction limitations on your account
o If you have any fund share certificates, you submit them and they are signed
  by each record owner exactly as the shares are registered
o Your request includes a signature guarantee if you:
  - Are selling over $100,000 or exchanging over $500,000 worth of shares
  - Changed your account registration or address within the last 30 days
  - Instruct the transfer agent to mail the check to an address different from
    the one on your account
  - Want the check paid to someone other than the account's record owner(s)

                                       62


  - Are transferring the sale proceeds to a Pioneer mutual fund account with a
    different registration


TRANSACTION LIMITATIONS
Your transactions are subject to certain limitations, including the limitation
on the purchase of the fund's shares within 30 calendar days of a redemption.
See "Excessive trading."


BUYING
You may buy fund shares from any financial intermediary that has a sales
agreement or other arrangement with the distributor.

You can buy shares at net asset value per share plus any applicable sales
charge. The distributor may reject any order until it has confirmed the order
in writing and received payment. Normally, your financial intermediary will
send your purchase request to the fund's transfer agent. CONSULT YOUR
INVESTMENT PROFESSIONAL FOR MORE INFORMATION. Your investment firm receives a
commission from the distributor, and may receive additional compensation from
Pioneer, for your purchase of fund shares.


MINIMUM INVESTMENT AMOUNTS


CLASS A AND CLASS C SHARES
Your initial investment must be at least $1,000. Additional investments must be
at least $100 for Class A shares and $500 for Class C shares.

You may qualify for lower initial or subsequent investment minimums if you are
opening a retirement plan account, establishing an automatic investment plan or
placing your trade through your investment firm. The fund may waive the initial
or subsequent investment minimums. Minimum investment amounts may be waived

intermediaries, such as broker-dealers and investment advisers, that have
entered into an agreement with Pioneer.


CLASS K SHARES
Initial investments by discretionary accounts and direct investors in Class K
shares must be at least $5 million. There is no investment minimum for other
eligible investors. This amount may be invested in one or more of the


                                       63


Buying, exchanging and selling shares

Pioneer mutual funds that currently offer Class K shares. There is no minimum
additional investment amount. The fund may waive the initial investment amount,
if applicable.


WAIVERS OF THE MINIMUM INVESTMENT AMOUNT FOR CLASS K
The fund will accept an initial investment of less than $5 million if:

(a)        The investment is made by a retirement plan that is an eligible
           investor in Class K shares; or

(b)        The investment is made by another Pioneer fund.

The fund reserves the right to waive the initial investment minimum in other
circumstances.


CLASS R SHARES
There is no minimum investment amount for Class R shares, although investments
are subject to the fund's policies regarding small accounts.


CLASS Y SHARES
Your initial investment in Class Y shares must be at least $5 million. This
amount may be invested in one or more of the Pioneer mutual funds that
currently offer Class Y shares. There is no minimum additional investment
amount. The fund may waive the initial investment amount.


WAIVERS OF THE MINIMUM INVESTMENT AMOUNT FOR CLASS Y
The fund will accept an initial investment of less than $5 million if:

(a)        The investment is made by a trust company or bank trust department
           which is initially investing at least $1 million in any of the
           Pioneer mutual funds and, at the time of the purchase, such assets
           are held in a fiduciary, advisory, custodial or similar capacity
           over which the trust company or bank trust department has full or
           shared investment discretion; or

(b)        The investment is at least $1 million in any of the Pioneer mutual
           funds and the purchaser is an insurance company separate account; or

(c)        The account is not represented by a broker-dealer and the investment
           is made by (1) an ERISA-qualified retirement plan that meets the
           requirements of Section 401 of the Internal Revenue Code, (2) an
           employer-sponsored retirement plan that meets the requirements of
           Sections 403 or 457 of the Internal Revenue Code, (3) a private
           foundation


                                       64


    that meets the requirements of Section 501(c)(3) of the Internal Revenue
    Code or (4) an endowment or other organization that meets the requirements
    of Section 509(a)(1) of the Internal Revenue Code; or

(d)        The investment is made by an employer-sponsored retirement plan
           established for the benefit of (1) employees of Pioneer or its
           affiliates, or (2) employees or the affiliates of broker-dealers who
           have a Class Y shares sales agreement with the distributor; or

(e)        The investment is made through certain mutual fund programs
           sponsored by qualified intermediaries, such as broker-dealers and
           investment advisers. In each case, the intermediary has entered into
           an agreement with Pioneer to include Class Y shares of the Pioneer
           mutual funds in their program. The intermediary provides investors
           participating in the program with additional services, including
           advisory, asset allocation, recordkeeping or other services. You
           should ask your investment firm if it offers and you are eligible to
           participate in such a mutual fund program and whether participation
           in the program is consistent with your investment goals. The
           intermediaries sponsoring or participating in these mutual fund
           programs may also offer their clients other classes of shares of the
           funds and investors may receive different levels of services or pay
           different fees depending upon the class of shares included in the
           program. Investors should consider carefully any separate
           transaction and other fees charged by these programs in connection
           with investing in each available share class before selecting a
           share class; or

(f)        The investment is made by another Pioneer fund.

The fund reserves the right to waive the initial investment minimum in other
circumstances.

is applied on a per transaction basis. Class A, Class K, Class R and Class Y
are not subject to a maximum purchase amount.

HOW TO BUY SHARES


THROUGH YOUR INVESTMENT FIRM
Normally, your investment firm will send your purchase request to the fund's
distributor and/or transfer agent. CONSULT YOUR INVESTMENT PROFESSIONAL FOR
MORE INFORMATION. Your investment firm receives a commission from the
distributor, and may receive additional compensation from Pioneer, for your
purchase of fund shares.


BY PHONE OR ONLINE
YOU CAN USE THE TELEPHONE OR ONLINE PURCHASE PRIVILEGE IF you have an existing
non-retirement account. Certain IRAs can use the telephone purchase privilege.
If your account is eligible, you can purchase additional fund shares by phone
or online if:
o You established your bank account of record at least 30 days ago
o Your bank information has not changed for at least 30 days
o You are not purchasing more than $100,000 worth of shares per account per day
o You can provide the proper account identification information

When you request a telephone or online purchase, the transfer agent will
electronically debit the amount of the purchase from your bank account of
record. The transfer agent will purchase fund shares for the amount of the
debit at the offering price determined after the transfer agent receives your
telephone or online purchase instruction and good funds. It usually takes three
business days for the transfer agent to receive notification from your bank
that good funds are available in the amount of your investment.


IN WRITING, BY MAIL
You can purchase fund shares for an existing fund account by MAILING A CHECK TO
THE FUND. Make your check payable to the fund. Neither initial nor subsequent
investments should be made by third party check, travelers check, or credit
card check. Your check must be in U.S. dollars and drawn


                                       66


on a U.S. bank. Include in your purchase request the fund's name, the account
number and the name or names in the account registration. Please note that
there may be a delay in receipt by the fund's transfer agent of purchase orders
submitted by regular mail to a post office address.


BY WIRE (CLASS K OR CLASS Y SHARES ONLY)
If you have an existing (Class K or Class Y shares only) account, you may wire
funds to purchase shares. Note, however, that:
o State Street Bank must receive your wire no later than 11:00 a.m. Eastern
  time on the business day after the fund receives your request to purchase
  shares
o If State Street Bank does not receive your wire by 11:00 a.m. Eastern time on
  the next business day, your transaction will be canceled at your expense and
  risk
o Wire transfers normally take two or more hours to complete and a fee may be
  charged by the sending bank
o Wire transfers may be restricted on holidays and at certain other times

The fund's transfer agent must receive your account application before you send
your initial check or federal funds wire. In addition, you must provide a bank
wire address of record when you establish your account.


EXCHANGING
You may, under certain circumstances, exchange your shares for shares of the
same class of another Pioneer mutual fund.

Your exchange request must be for at least $1,000. The fund allows you to
exchange your shares at net asset value without charging you either an initial
or contingent deferred sales charge at the time of the exchange. Shares you
acquire as part of an exchange will continue to be subject to


                                       67


Buying, exchanging and selling shares

any contingent deferred sales charge that applies to the shares you originally
purchased. When you ultimately sell your shares, the date of your original
purchase will determine your contingent deferred sales charge.

Before you request an exchange, consider each fund's investment objective and
policies as described in the fund's prospectus. You generally will have to pay
income taxes on an exchange.


SAME-FUND EXCHANGE PRIVILEGE
Certain shareholders may be eligible to exchange their shares for the fund's
Class Y or Class K shares. If eligible, no sales charges or other charges will
apply to any such exchange. Generally, shareholders will not recognize a gain
or loss for federal income tax purposes upon such an exchange. Investors should
contact their financial intermediary to learn more about the details of this
privilege.


HOW TO EXCHANGE SHARES


THROUGH YOUR INVESTMENT FIRM
Normally, your investment firm will send your exchange request to the fund's
transfer agent. CONSULT YOUR INVESTMENT PROFESSIONAL FOR MORE INFORMATION ABOUT
EXCHANGING YOUR SHARES.


BY PHONE OR ONLINE
After you establish an eligible fund account, YOU CAN EXCHANGE FUND SHARES BY
PHONE OR ONLINE IF:
o You are exchanging into an existing account or using the exchange to
  establish a new account, provided the new account has a registration
  identical to the original account
o The fund into which you are exchanging offers the same class of shares
o You are not exchanging more than $500,000 worth of shares per account per day
o You can provide the proper account identification information


IN WRITING, BY MAIL OR BY FAX
You can exchange fund shares by MAILING OR FAXING A LETTER OF INSTRUCTION TO
THE FUND. You can exchange fund shares directly through the fund only if your
account is registered in your name. However, you may not fax an exchange
request for more than $500,000. Include in your letter:
o The name and signature of all registered owners

                                       68

  is more than $500,000
o The name of the fund out of which you are exchanging and the name of the fund
  into which you are exchanging
o The class of shares you are exchanging
o The dollar amount or number of shares you are exchanging

Please note that there may be a delay in receipt by the fund's transfer agent
of exchange requests submitted by regular mail to a post office address.


SELLING
Your shares will be sold at the share price (net asset value less any
applicable sales charge) next calculated after the fund or its authorized
agent, such as a broker-dealer, receives your request in good order. If a
signature guarantee is required, you must submit your request in writing.

If the shares you are selling are subject to a deferred sales charge, it will
be deducted from the sale proceeds. The fund generally will send your sale
proceeds by check, bank wire or electronic funds transfer. Normally you will be
paid within seven days. If you recently sent a check to purchase the shares
being sold, the fund may delay payment of the sale proceeds until your check
has cleared. This may take up to 10 calendar days from the purchase date.

If you are selling shares from a non-retirement account or certain IRAs, you
may use any of the methods described below. If you are selling shares from a
retirement account other than an IRA, you must make your request in writing.

You generally will have to pay income taxes on a sale.

If you must use a written request to exchange or sell your shares and your
account is registered in the name of a corporation or other fiduciary you must
include the name of an authorized person and a certified copy of a current
corporate resolution, certificate of incumbency or similar legal document
showing that the named individual is authorized to act on behalf of the record
owner.

HOW TO SELL SHARES


THROUGH YOUR INVESTMENT FIRM

fund's transfer agent. CONSULT YOUR INVESTMENT PROFESSIONAL FOR MORE

the right to terminate this procedure at any time.

See the account application form for more details on each of the following
services or call the fund for details and availability.


TELEPHONE TRANSACTION PRIVILEGES
If your account is registered in your name, you can buy, exchange or sell fund
shares by telephone. If you do not want your account to have telephone
transaction privileges, you must indicate that choice on your account
application or by writing to the fund.

When you request a telephone transaction the fund's transfer agent will try to
confirm that the request is genuine. The transfer agent records the call,
requires the caller to provide validating information for the account and sends
you a written confirmation. The fund may implement other confirmation
procedures from time to time. Different procedures may apply if you have a
non-U.S. account or if your account is registered in the name of an
institution, broker-dealer or other third party. If the fund's confirmation
procedures are followed, neither the fund nor its agents will bear any
liability for these transactions.


ONLINE TRANSACTION PRIVILEGES
If your account is registered in your name, you may be able to buy, exchange or
sell fund shares online. Your investment firm may also be able to buy, exchange
or sell your fund shares online.

To establish online transaction privileges:
o For new accounts, complete the online section of the account application
o For existing accounts, complete an account options form, write to the
  fund or complete the online authorization screen at
  us.pioneerinvestments.com

To use online transactions, you must read and agree to the terms of an online
transaction agreement available on the Pioneer website. When you or your
investment firm requests an online transaction the fund's transfer agent
electronically records the transaction, requires an authorizing password and
sends a written confirmation. The fund may implement other procedures from time
to time. Different procedures may apply if you have a non-U.S. account or if
your account is registered in the name of an institution, broker-dealer or
other third party. You may not be able to use the online transaction privilege
for certain types of accounts, including most retirement accounts.


                                       72


AUTOMATIC INVESTMENT PLANS
You can make regular periodic investments in the fund by setting up monthly
bank drafts, government allotments, payroll deductions, a Pioneer Investomatic
Plan and other similar automatic investment plans. Automatic investments may be
made only through U.S. banks. You may use an automatic investment plan to
establish a Class A share account with a small initial investment. If you have
a Class C or Class R share account and your balance is at least $1,000, you may
establish an automatic investment plan.


PIONEER INVESTOMATIC PLAN
If you establish a Pioneer Investomatic Plan, the transfer agent will make a
periodic investment in fund shares by means of a preauthorized electronic funds
transfer from your bank account. Your plan investments are voluntary. You may
discontinue your plan at any time or change the plan's dollar amount, frequency
or investment date by calling or writing to the transfer agent. You should
allow up to 30 days for the transfer agent to establish your plan.


AUTOMATIC EXCHANGES
You can automatically exchange your fund shares for shares of the same class of
another Pioneer mutual fund. The automatic exchange will begin on the day you
select when you complete the appropriate section of your account application or
an account options form. In order to establish automatic exchange:
o You must select exchanges on a monthly or quarterly basis
o Both the originating and receiving accounts must have identical registrations
o The originating account must have a minimum balance of $5,000

You may have to pay income taxes on an exchange.


DISTRIBUTION OPTIONS
The fund offers three distribution options. Any fund shares you buy by
reinvesting distributions will be priced at the applicable net asset value per
share.

(1)   Unless you indicate another option on your account application, any
      dividends and capital gain distributions paid to you by the fund will
      automatically be invested in additional fund shares.

(2)   You may elect to have the amount of any dividends paid to you in cash and
      any capital gain distributions reinvested in additional shares.


                                       73


Account options

(3)   You may elect to have the full amount of any dividends and/or capital
      gain distributions paid to you in cash.

Options (2) and (3) are not available to retirement plan accounts or accounts
with a current value of less than $500.

If you are under 59 1/2, taxes and tax penalties may apply.

If your distribution check is returned to the transfer agent or you do not cash
the check for six months or more, the transfer agent may reinvest the amount of
the check in your account and automatically change the distribution option on
your account to option (1) until you request a different option in writing. If
the amount of a distribution check would be less than $25, the fund may
reinvest the amount in additional shares of the fund instead of sending a
check. Additional shares of the fund will be purchased at the then-current net
asset value.


DIRECTED DIVIDENDS
You can invest the dividends paid by one of your Pioneer mutual fund accounts
in a second Pioneer mutual fund account. The value of your second account must
be at least $1,000. You may direct the investment of any amount of dividends.
There are no fees or charges for directed dividends. If you have a retirement
plan account, you may only direct dividends to accounts with identical
registrations.


SYSTEMATIC WITHDRAWAL PLANS
When you establish a systematic withdrawal plan for your account, the transfer
agent will sell the number of fund shares you specify on a periodic basis and
the proceeds will be paid to you or to any person you select. You must obtain a
signature guarantee to direct payments to another person after you have
established your systematic withdrawal plan. Payments can be made either by
check or by electronic transfer to a U.S. bank account you designate.

To establish a systematic withdrawal plan:
o Your account must have a total value of at least $10,000 when you establish
  your plan
o You may not request a periodic withdrawal of more than 10% of the value of
  any Class C or Class R share account (valued at the time the plan is
  implemented)


                                       74


These requirements do not apply to scheduled (Internal Revenue Code Section
72(t) election) or mandatory (required minimum distribution) withdrawals from
IRAs and certain retirement plans.

Systematic sales of fund shares may be taxable transactions for you. While you
are making systematic withdrawals from your account, you may pay unnecessary
initial sales charges on additional purchases of Class A shares or contingent
deferred sales charges.


DIRECT DEPOSIT
If you elect to take dividends or dividends and capital gain distributions in
cash, or if you establish a systematic withdrawal plan, you may choose to have
those cash payments deposited directly into your savings, checking or NOW bank
account.


VOLUNTARY TAX WITHHOLDING
You may have the transfer agent withhold 28% of the dividends and capital gain
distributions paid from your fund account (before any reinvestment) and forward
the amount withheld to the Internal Revenue Service as a credit against your
federal income taxes. Voluntary tax withholding is not available for retirement
plan accounts or for accounts subject to backup withholding.


                                       75


Shareholder services and policies

EXCESSIVE TRADING
Frequent trading into and out of the fund can disrupt portfolio management
strategies, harm fund performance by forcing the fund to hold excess cash or to
liquidate certain portfolio securities prematurely and increase expenses for
all investors, including long-term investors who do not generate these costs.
An investor may use short-term trading as a strategy, for example, if the
investor believes that the valuation of the fund's portfolio securities for
purposes of calculating its net asset value does not fully reflect the
then-current fair market value of those holdings. The fund discourages, and
does not take any intentional action to accommodate, excessive and short-term
trading practices, such as market timing. Although there is no generally
applied standard in the marketplace as to what level of trading activity is
excessive, we may consider trading in the fund's shares to be excessive for a
variety of reasons, such as if:
o You sell shares within a short period of time after the shares were
  purchased;
o You make two or more purchases and redemptions within a short period of time;
o You enter into a series of transactions that indicate a timing pattern or
  strategy; or
o We reasonably believe that you have engaged in such practices in connection
  with other mutual funds.

The fund's Board of Trustees has adopted policies and procedures with respect
to frequent purchases and redemptions of fund shares by fund investors.
Pursuant to these policies and procedures, we monitor selected trades on a
daily basis in an effort to detect excessive short-term trading. If we
determine that an investor or a client of a broker or other intermediary has
engaged in excessive short-term trading that we believe may be harmful to the
fund, we will ask the investor, broker or other intermediary to cease such
activity and we will refuse to process purchase orders (including purchases by
exchange) of such investor, broker, other intermediary or accounts that we
believe are under their control. In determining whether to take such actions,
we seek to act in a manner that is consistent with the best interests of the
fund's shareholders.

While we use our reasonable efforts to detect excessive trading activity, there
can be no assurance that our efforts will be successful or that market timers
will not employ tactics designed to evade detection. If we are not successful,
your return from an investment in the fund may be adversely affected.
Frequently, fund shares are held through omnibus accounts maintained by
financial intermediaries such as brokers and retirement plan administrators,


                                       76


where the holdings of multiple shareholders, such as all the clients of a
particular broker or other intermediary, are aggregated. Our ability to monitor
trading practices by investors purchasing shares through omnibus accounts may
be limited and dependent upon the cooperation of the broker or other
intermediary in taking steps to limit this type of activity.

The fund may reject a purchase or exchange order before its acceptance or the
issuance of shares. The fund may also restrict additional purchases or
exchanges in an account. Each of these steps may be taken for any transaction,
for any reason, without prior notice, including transactions that the fund
believes are requested on behalf of market timers. The fund reserves the right
to reject any purchase or exchange request by any investor or financial
institution if the fund believes that any combination of trading activity in
the account or related accounts is potentially disruptive to the fund. A
prospective investor whose purchase or exchange order is rejected will not
achieve the investment results, whether gain or loss, that would have been
realized if the order had been accepted and an investment made in the fund. A
fund and its shareholders do not incur any gain or loss as a result of a
rejected order. The fund may impose further restrictions on trading activities
by market timers in the future.

To limit the negative effects of excessive trading on the fund, the fund has
adopted the following restriction on investor transactions. If an investor
redeems $5,000 or more (including redemptions that are a part of an exchange
transaction) from the fund, that investor shall be prevented (or "blocked")
from purchasing shares of the fund (including purchases that are a part of an
exchange transaction) for 30 calendar days after the redemption. This policy
does not apply to systematic purchase or withdrawal plan transactions,
transactions made through employer-sponsored retirement plans described under
Section 401(a), 403(b) or 457 of the Internal Revenue Code or employee benefit

Shareholder services and policies

We rely on financial intermediaries that maintain omnibus accounts to apply to
their customers either the fund's policy described above or their own policies
or restrictions designed to limit excessive trading of fund shares. However, we
do not impose this policy at the omnibus account level.

Purchases pursuant to the reinstatement privilege (for Class A shares) are
subject to this policy.


PURCHASES IN KIND
You may use securities you own to purchase shares of the fund provided that
Pioneer, in its sole discretion, determines that the securities are consistent
with the fund's objectives and policies and their acquisition is in the best
interests of the fund. If the fund accepts your securities, they will be valued
for purposes of determining the number of fund shares to be issued to you in
the same way the fund will value the securities for purposes of determining its
net asset value. For federal income tax purposes, you may be taxed in the same
manner as if you sold the securities that you use to purchase fund shares for
cash in an amount equal to the value of the fund shares that you purchase. Your
broker may also impose a fee in connection with processing your purchase of
fund shares with securities.


REINSTATEMENT PRIVILEGE (CLASS A SHARES)
If you recently sold all or part of your Class A shares, you may be able to
reinvest all or part of your sale proceeds without a sales charge in Class A
shares of any Pioneer mutual fund. To qualify for reinstatement:
o You must send a written request to the fund no more than 90 days after
  selling your shares and
o The registration of the account in which you reinvest your sale proceeds must
  be identical to the registration of the account from which you sold your
  shares.

Purchases pursuant to the reinstatement privilege are subject to limitations on
investor transactions, including the limitation on the purchase of the fund's
shares within 30 calendar days of redemption. See "Excessive trading."

When you elect reinstatement, you are subject to the provisions outlined in the
selected fund's prospectus, including the fund's minimum investment
requirement. Your sale proceeds will be reinvested in shares of the fund at the
Class A net asset value per share determined after the fund receives your
written request for reinstatement. You may realize a gain or loss for


                                       78


federal income tax purposes as a result of your sale of fund shares, and
special tax rules may apply if you elect reinstatement. Consult your tax
adviser for more information.

Shareholder services and policies

or in writing (see "How to contact us"). Pioneer will begin mailing separate
proxy statements, prospectuses and shareowner reports to you within 30 days
after receiving your notice.


CONFIRMATION STATEMENTS
The fund's transfer agent maintains an account for each investment firm or
individual shareowner and records all account transactions. You will be sent
confirmation statements showing the details of your transactions as they occur,
except automatic investment plan transactions, which are confirmed quarterly.
If you have more than one Pioneer mutual fund account registered in your name,
the Pioneer combined account statement will be mailed to you each quarter.


TAX INFORMATION

dividends and distributions paid to you by the fund.


TAX INFORMATION FOR IRA ROLLOVERS
In January (or by the applicable Internal Revenue Service deadline) following
the year in which you take a reportable distribution, the fund's transfer agent
will mail you a tax form reflecting the total amount(s) of distribution(s)
received by the end of January.


PRIVACY
The fund has a policy designed to protect the privacy of your personal
information. A copy of Pioneer's privacy notice was given to you at the time
you opened your account. The fund will send you a copy of the privacy notice
each year. You may also obtain the privacy notice by calling the fund or
through Pioneer's website.


SIGNATURE GUARANTEES AND OTHER REQUIREMENTS
You are required to obtain a signature guarantee when:
o Requesting certain types of exchanges or sales of fund shares
o Redeeming shares for which you hold a share certificate
o Requesting certain types of changes for your existing account

You can obtain a signature guarantee from most broker-dealers, banks, credit
unions (if authorized under state law) and federal savings and loan
associations. You cannot obtain a signature guarantee from a notary public.


                                       80


The Pioneer funds generally accept only medallion signature guarantees. A
medallion signature guarantee may be obtained from a domestic bank or trust
company, broker, dealer, clearing agency, savings association, or other
financial institution that is participating in a medallion program recognized
by the Securities Transfer Association. Signature guarantees from financial
institutions that are not participating in one of these programs are not
accepted as medallion signature guarantees. The fund may accept other forms of
guarantee from financial intermediaries in limited circumstances.

Fiduciaries and corporations are required to submit additional documents to
sell fund shares.


MINIMUM ACCOUNT SIZE
The fund requires that you maintain a minimum account value of $500. If you
hold less than $500 in your account, the fund reserves the right to notify you
that it intends to sell your shares and close your account. You will be given
60 days from the date of the notice to make additional investments to avoid
having your shares sold. This policy does not apply to certain qualified
retirement plan accounts.


TELEPHONE AND WEBSITE ACCESS
You may have difficulty contacting the fund by telephone or accessing
us.pioneerinvestments.com during times of market volatility or disruption in
telephone or Internet service. On New York Stock Exchange holidays or on days
when the exchange closes early, Pioneer will adjust the hours for the telephone
center and for online transaction processing accordingly. If you are unable to
access us.pioneerinvestments.com or reach the fund by telephone, you should
communicate with the fund in writing.


SHARE CERTIFICATES
The fund does not offer share certificates. Shares are electronically recorded.
Any existing certificated shares can only be sold by returning your certificate
to the transfer agent, along with a letter of instruction or a stock power (a
separate written authority transferring ownership) and a signature guarantee.


OTHER POLICIES
The fund and the distributor reserve the right to:
o reject any purchase or exchange order for any reason, without prior notice

                                       81


Shareholder services and policies

o charge a fee for exchanges or to modify, limit or suspend the exchange
  privilege at any time without notice. The fund will provide 60 days' notice
  of material amendments to or termination of the exchange privilege
o revise, suspend, limit or terminate the account options or services available
  to shareowners at any time, except as required by the rules of the
  Securities and Exchange Commission

The fund reserves the right to:
o suspend transactions in shares when trading on the New York Stock Exchange is
  closed or restricted, or when the Securities and Exchange Commission
  determines an emergency or other circumstances exist that make it
  impracticable for the fund to sell or value its portfolio securities, or
  otherwise as permitted by the rules of or by the order of the Securities and
  Exchange Commission
o redeem in kind by delivering to you portfolio securities owned by the fund
  rather than cash. Securities you receive this way may increase or decrease
  in value while you hold them and you may incur brokerage and transaction
  charges and tax liability when you convert the securities to cash
o charge transfer, shareholder servicing or similar agent fees, such as an
  account maintenance fee for small balance accounts, directly to accounts
  upon at least 30 days' notice. The fund may do this by deducting the fee
  from your distribution of dividends and/or by redeeming fund shares to the
  extent necessary to cover the fee
o close your account after a period of inactivity, as determined by state law,
  and transfer your shares to the appropriate state


                                       82


Dividends, capital gains and taxes

DIVIDENDS AND CAPITAL GAINS
The fund declares dividends daily. The daily dividends consist of substantially
all of the fund's net income (excluding any net short- and long-term capital
gains). You begin to earn dividends on the first business day following receipt
of payment for shares. You continue to earn dividends up to and including the
date of sale. Dividends are normally paid on the last business day of each
month.

The fund generally pays any distribution of net short- and long-term capital
gains in November. The fund may also pay dividends and capital gain
distributions at other times if necessary for the fund to avoid U.S. federal
income or excise tax. If you invest in the fund shortly before a distribution
described in this paragraph, generally you will pay a higher price per share
and, unless you are exempt from tax, you will pay taxes on the amount of the
distribution whether you reinvest the distribution in additional shares or
receive it as cash.


TAXES
You will normally have to pay federal income taxes, and any state or local
taxes, on the dividends and other distributions you receive from the fund,
whether you take the distributions in cash or reinvest them in additional
shares. For U.S. federal income tax purposes, distributions from the fund's net
capital gains (if any) are considered long-term capital gains and are generally
taxable to noncorporate shareholders at rates of up to 20%. Distributions from
the fund's net short-term capital gains are generally taxable as ordinary
income. Other dividends are generally taxable as ordinary income. Since the
fund's income is derived primarily from sources that do not pay dividends, it
is not expected that a substantial portion of the dividends paid by the fund
will qualify either for the dividends-received deduction for corporations or
for any favorable U.S. federal income tax rate available to noncorporate
shareholders on "qualified dividend income."

The fund will report to shareholders annually the U.S. federal income tax
status of all fund distributions.

If the fund declares a dividend in October, November or December, payable to
shareholders of record in such a month, and pays it in January of the following
year, you will be taxed on the dividend as if you received it in the year in
which it was declared.


                                       83


Dividends, capital gains and taxes

Sales and exchanges generally will be taxable transactions to shareowners. When
you sell or exchange fund shares you will generally recognize a capital gain or
capital loss in an amount equal to the difference between the net amount of
sale proceeds (or, in the case of an exchange, the fair market value of the
shares) that you receive and your tax basis for the shares that you sell or
exchange.

A 3.8% Medicare contribution tax generally applies to all or a portion of the
net investment income of a shareholder who is an individual and not a
nonresident alien for federal income tax purposes and who has adjusted gross
income (subject to certain adjustments) that exceeds a threshold amount. This
3.8% tax also applies to all or a portion of the undistributed net investment
income of certain shareholders that are estates and trusts. For these purposes,
dividends, interest and certain capital gains are generally taken into account
in computing a shareholder's net investment income.

You must provide your social security number or other taxpayer identification
number to the fund along with the certifications required by the Internal
Revenue Service when you open an account. If you do not or if it is otherwise
legally required to do so, the fund will apply "backup withholding" tax on your
dividends and other distributions, sale proceeds and any other payments to you
that are subject to backup withholding. The backup withholding rate is 28%.

Shareholders that are exempt from U.S. federal income tax, such as retirement
plans that are qualified under Section 401 of the Internal Revenue Code,
generally are not subject to U.S. federal income tax on fund dividends or other
distributions or on sales or exchanges of fund shares. However, in the case of
fund shares held through a nonqualified deferred compensation plan, fund
dividends and other distributions received by the plan and sales and exchanges
of fund shares by the plan generally will be taxable to the employer sponsoring
such plan in accordance with U.S. federal income tax laws that are generally
applicable to shareholders receiving such dividends and other distributions
from regulated investment companies such as the fund or effecting such sales or
exchanges.

Plan participants whose retirement plan invests in the fund generally are not
subject to federal income tax on fund dividends or other distributions received
by the plan or on sales or exchanges of fund shares by the plan. However,
distributions to plan participants from a retirement plan generally are taxable
to plan participants as ordinary income.


                                       84


Distributions derived from interest on U.S. government obligations (but
generally not distributions of gain from the sale of such obligations) may be
exempt from certain state and local taxes.

You should ask your tax adviser about any federal, state, local and foreign tax
considerations relating to an investment in the fund. You may also consult the
fund's statement of additional information for a more detailed discussion of
the U.S. federal income tax considerations that may affect the fund and its
shareowners.

1. FUND HISTORY

The fund is a diversified open-end management investment company. The fund is a
series of Pioneer Bond Fund (the "Trust"). The Trust was originally organized
as a Massachusetts corporation on August 16, 1978, reorganized as a
Massachusetts business trust on December 31, 1985 and reorganized as a Delaware
statutory trust on May 17, 1999. Pioneer Investment Management, Inc.
("Pioneer") is the fund's investment adviser.


2. INVESTMENT POLICIES, RISKS AND RESTRICTIONS

The prospectus presents the investment objectives and the principal investment
strategies and risks of the fund. This section supplements the disclosure in
the fund's prospectus and provides additional information on the fund's
investment policies or restrictions. Restrictions or policies stated as a
maximum percentage of the fund's assets are only applied immediately after a
portfolio investment to which the policy or restriction is applicable (other
than the limitations on borrowing and illiquid securities). Accordingly, any
later increase or decrease in a percentage resulting from a change in values,
net assets or other circumstances will not be considered in determining whether
the investment complies with the fund's restrictions and policies.


DEBT SECURITIES AND RELATED INVESTMENTS


DEBT SECURITIES RATING INFORMATION
Investment grade debt securities are those rated "BBB" or higher by Standard &
Poor's Ratings Group ("Standard & Poor's") or the equivalent rating of other
nationally recognized statistical rating organizations. Debt securities rated
BBB are considered medium grade obligations with speculative characteristics,
and adverse economic conditions or changing circumstances may weaken the
issuer's ability to pay interest and repay principal.

Below investment grade debt securities are those rated "BB" and below by
Standard & Poor's or the equivalent rating of other nationally recognized
statistical rating organizations. See "Appendix A" for a description of rating
categories. The fund may invest in debt securities rated "D" or better, or
comparable unrated securities as determined by Pioneer.

Below investment grade debt securities or comparable unrated securities are
commonly referred to as "junk bonds" and are considered predominantly
speculative and may be questionable as to principal and interest payments.
Changes in economic conditions are more likely to lead to a weakened capacity
to make principal payments and interest payments. The issuers of high yield
securities also may be more adversely affected than issuers of higher rated
securities by specific corporate or governmental developments or the issuers'
inability to meet specific projected business forecasts. The amount of high
yield securities outstanding has proliferated as an increasing number of
issuers have used high yield securities for corporate financing. The recent
economic downturn has severely affected the ability of many highly leveraged
issuers to service their debt obligations or to repay their obligations upon
maturity. Factors having an adverse impact on the market value of lower quality
securities will have an adverse effect on the fund's net asset value to the
extent that it invests in such securities. In addition, the fund may incur
additional expenses to the extent it is required to seek recovery upon a
default in payment of principal or interest on its portfolio holdings or to
take other steps to protect its investment in an issuer.

The secondary market for high yield securities is not usually as liquid as the
secondary market for more highly rated securities, a factor which may have an
adverse effect on the fund's ability to dispose of a particular security when
necessary to meet its liquidity needs. Under adverse market or economic
conditions, such as those recently prevailing, the secondary market for high
yield securities could contract further, independent of any specific adverse
changes in the condition of a particular issuer. As a result, the fund


                                       1


could find it more difficult to sell these securities or may be able to sell
the securities only at prices lower than if such securities were widely traded.
Prices realized upon the sale of such lower rated or unrated securities, under
these and other circumstances, may be less than the prices used in calculating
the fund's net asset value.

Since investors generally perceive that there are greater risks associated with
lower quality debt securities of the type in which the fund may invest, the
yields and prices of such securities may tend to fluctuate more than those for
higher rated securities. In the lower quality segments of the debt securities
market, changes in perceptions of issuers' creditworthiness tend to occur more
frequently and in a more pronounced manner than do changes in higher quality
segments of the debt securities market, resulting in greater yield and price
volatility.

Lower rated and comparable unrated debt securities tend to offer higher yields
than higher rated securities with the same maturities because the historical
financial condition of the issuers of such securities may not have been as
strong as that of other issuers. However, lower rated securities generally
involve greater risks of loss of income and principal than higher rated
securities.

For purposes of the fund's credit quality policies, if a security receives
different ratings from nationally recognized statistical rating organizations,
the fund will use the rating chosen by the portfolio manager as most
representative of the security's credit quality. The ratings of nationally
recognized statistical rating organizations represent their opinions as to the
quality of the securities that they undertake to rate and may not accurately
describe the risk of the security. If a rating organization changes the quality
rating assigned to one or more of the fund's portfolio securities, Pioneer will
consider if any action is appropriate in light of the fund's investment
objectives and policies.


U.S. GOVERNMENT SECURITIES
U.S. government securities in which the fund invests include debt obligations
of varying maturities issued by the U.S. Treasury or issued or guaranteed by an
agency, authority or instrumentality of the U.S. government, including the
Federal Housing Administration, Federal Financing Bank, Farm Service Agency,
Export-Import Bank of the U.S., Small Business Administration, Government
National Mortgage Association ("GNMA"), General Services Administration,
National Bank for Cooperatives, Federal Farm Credit Banks, Federal Home Loan
Banks ("FHLBs"), Federal Home Loan Mortgage Corporation ("FHLMC"), Federal
National Mortgage Association ("FNMA"), Maritime Administration, Tennessee
Valley Authority and various institutions that previously were or currently are
part of the Farm Credit System (which has been undergoing reorganization since
1987). Some U.S. government securities, such as U.S. Treasury bills, Treasury
notes and Treasury bonds, which differ only in their interest rates, maturities
and times of issuance, are supported by the full faith and credit of the United
States. Others are supported by: (i) the right of the issuer to borrow from the
U.S. Treasury, such as securities of the FHLBs; (ii) the discretionary
authority of the U.S. government to purchase the agency's obligations, such as
securities of FNMA; or (iii) only the credit of the issuer. Such debt
securities are subject to the risk of default on the payment of interest and/or
principal, similar to debt of private issuers. The maximum potential liability
of some U.S. government securities may greatly exceed their current resources,
including any legal right to support from the U.S. government. Although the
U.S. government provided financial support to FNMA and FHLMC in the past, no
assurance can be given that the U.S. government will provide financial support
in the future to these or other U.S. government agencies, authorities or
instrumentalities that are not supported by the full faith and credit of the
United States. Securities guaranteed as to principal and interest by the U.S.
government, its agencies, authorities or instrumentalities include: (i)
securities for which the payment of principal and interest is backed by an
irrevocable letter of credit issued by the U.S. government or any of its
agencies, authorities or instrumentalities; (ii) participations in loans made
to non-U.S. governments or other entities that are so guaranteed; and (iii) as
a result of initiatives introduced in response to the recent financial market
difficulties, securities of commercial issuers or financial institutions that
qualify for guarantees by U.S. government agencies like the Federal Deposit
Insurance Corporation. The secondary market for certain loan participations
described above is limited and, therefore, the participations may be regarded
as illiquid.


                                       2


U.S. government securities may include zero coupon securities that may be
purchased when yields are attractive and/or to enhance portfolio liquidity.
Zero coupon U.S. government securities are debt obligations that are issued or
purchased at a significant discount from face value. The discount approximates
the total amount of interest the security will accrue and compound over the
period until maturity or the particular interest payment date at a rate of
interest reflecting the market rate of the security at the time of issuance.
Zero coupon U.S. government securities do not require the periodic payment of
interest. These investments may experience greater volatility in market value
than U.S. government securities that make regular payments of interest. The
fund accrues income on these investments for tax and accounting purposes, which
is distributable to shareholders and which, because no cash is received at the
time of accrual, may require the liquidation of other portfolio securities to
satisfy the fund's distribution obligations, in which case the fund will forgo
the purchase of additional income producing assets with these funds. Zero
coupon U.S. government securities include STRIPS and CUBES, which are issued by
the U.S. Treasury as component parts of U.S. Treasury bonds and represent
scheduled interest and principal payments on the bonds.


CONVERTIBLE DEBT SECURITIES
The fund may invest in convertible debt securities which are debt obligations
convertible at a stated exchange rate or formula into common stock or other
equity securities. Convertible securities rank senior to common stocks in an
issuer's capital structure and consequently may be of higher quality and entail
less risk than the issuer's common stock. As with all debt securities, the
market values of convertible securities tend to increase when interest rates
decline and, conversely, tend to decline when interest rates increase.
Depending on the relationship of the conversion price to the market value of
the underlying securities, convertible securities may trade more like equity
securities than debt securities.

A convertible security entitles the holder to receive interest that is
generally paid or accrued until the convertible security matures, or is
redeemed, converted, or exchanged. Convertible securities have unique
investment characteristics, in that they generally (i) have higher yields than
common stocks, but lower yields than comparable non-convertible securities,
(ii) are less subject to fluctuation in value than the underlying common stock
due to their fixed-income characteristics and (iii) provide the potential for
capital appreciation if the market price of the underlying common stock
increases. A convertible security may be subject to redemption at the option of
the issuer at a price established in the convertible security's governing
instruments. If a convertible security held by the fund is called for
redemption, the fund will be required to permit the issuer to redeem the
security, convert it into the underlying common stock or sell it to a third
party. Any of these actions could result in losses to the fund.


MUNICIPAL OBLIGATIONS
The fund may purchase municipal obligations. The term "municipal obligations"
generally is understood to include debt obligations issued by municipalities to
obtain funds for various public purposes, the income from which is, in the
opinion of bond counsel to the issuer, excluded from gross income for U.S.
federal income tax purposes. In addition, if the proceeds from private activity
bonds are used for the construction, repair or improvement of privately
operated industrial or commercial facilities, the interest paid on such bonds
may be excluded from gross income for U.S. federal income tax purposes,
although current federal tax laws place substantial limitations on the size of
these issues. The fund's distributions of any interest it earns on municipal
obligations will be taxable as ordinary income to shareholders that are
otherwise subject to tax.

The two principal classifications of municipal obligations are "general
obligation" and "revenue" bonds. General obligation bonds are secured by the
issuer's pledge of its faith, credit, and taxing power for the payment of
principal and interest. Revenue bonds are payable from the revenues derived
from a particular facility or class of facilities or, in some cases, from the
proceeds of a special excise or other specific revenue source, but not from the
general taxing power. Sizable investments in these obligations could involve an
increased risk to the fund should any of the related facilities experience
financial difficulties.


                                       3


Private activity bonds are in most cases revenue bonds and do not generally
carry the pledge of the credit of the issuing municipality. There are, of
course, variations in the security of municipal obligations, both within a
particular classification and between classifications.


MORTGAGE-BACKED SECURITIES
The fund may invest in mortgage pass-through certificates and multiple-class
pass-through securities, such as real estate mortgage investment conduits
("REMIC") pass-through certificates, collateralized mortgage obligations
("CMOs") and stripped mortgage-backed securities ("SMBS"), and other types of
mortgage-backed securities ("MBS") that may be available in the future. A
mortgage-backed security is an obligation of the issuer backed by a mortgage or
pool of mortgages or a direct interest in an underlying pool of mortgages. Some
mortgage-backed securities, such as CMOs, make payments of both principal and
interest at a variety of intervals; others make semiannual interest payments at
a predetermined rate and repay principal at maturity (like a typical bond).
Mortgage-backed securities are based on different types of mortgages including
those on commercial real estate or residential properties. Mortgage-backed
securities often have stated maturities of up to thirty years when they are
issued, depending upon the length of the mortgages underlying the securities.
In practice, however, unscheduled or early payments of principal and interest
on the underlying mortgages may make the securities' effective maturity shorter
than this, and the prevailing interest rates may be higher or lower than the
current yield of the portfolio at the time the fund receives the payments for
reinvestment. Mortgage-backed securities may have less potential for capital
appreciation than comparable fixed income securities, due to the likelihood of
increased prepayments of mortgages as interest rates decline. If the fund buys
mortgage-backed securities at a premium, mortgage foreclosures and prepayments
of principal by mortgagors (which may be made at any time without penalty) may
result in some loss of the fund's principal investment to the extent of the
premium paid.

The value of mortgage-backed securities may also change due to shifts in the
market's perception of issuers. In addition, regulatory or tax changes may
adversely affect the mortgage securities markets as a whole. Non-governmental
mortgage-backed securities may offer higher yields than those issued by
government entities, but also may be subject to greater price changes than
governmental issues.

Through its investments in mortgage-backed securities, including those that are
issued by private issuers, the fund may have exposure to subprime loans as well
as to the mortgage and credit markets generally. Private issuers include
commercial banks, savings associations, mortgage companies, investment banking
firms, finance companies and special purpose finance entities (called special
purpose vehicles or "SPVs") and other entities that acquire and package
mortgage loans for resale as MBS.

Unlike mortgage-backed securities issued or guaranteed by the U. S. government
or one of its sponsored entities, mortgage-backed securities issued by private
issuers do not have a government or government-sponsored entity guarantee, but
may have credit enhancement provided by external entities such as banks or
financial institutions or achieved through the structuring of the transaction
itself. Examples of such credit support arising out of the structure of the
transaction include the issue of senior and subordinated securities (e.g., the
issuance of securities by an SPV in multiple classes or "tranches", with one or
more classes being senior to other subordinated classes as to the payment of
principal and interest, with the result that defaults on the underlying
mortgage loans are borne first by the holders of the subordinated class);
creation of "reserve funds" (in which case cash or investments, sometimes
funded from a portion of the payments on the underlying mortgage loans, are
held in reserve against future losses); and "overcollateralization" (in which
case the scheduled payments on, or the principal amount of, the underlying
mortgage loans exceeds that required to make payment of the securities and pay
any servicing or other fees). However, there can be no guarantee that credit
enhancements, if any, will be sufficient to prevent losses in the event of
defaults on the underlying mortgage loans.

In addition, mortgage-backed securities that are issued by private issuers are
not subject to the underwriting requirements for the underlying mortgages that
are applicable to those mortgage-backed securities that have a government or
government-sponsored entity guarantee. As a result, the mortgage loans
underlying


                                       4


private mortgage-backed securities may, and frequently do, have less favorable
collateral, credit risk or other underwriting characteristics than government
or government-sponsored mortgage-backed securities and have wider variances in
a number of terms including interest rate, term, size, purpose and borrower
characteristics. Privately issued pools more frequently include second
mortgages, high loan-to-value mortgages and manufactured housing loans. The
coupon rates and maturities of the underlying mortgage loans in a private
mortgage-backed securities pool may vary to a greater extent than those
included in a government guaranteed pool, and the pool may include subprime
mortgage loans. Subprime loans refer to loans made to borrowers with weakened
credit histories or with a lower capacity to make timely payments on their
loans. For these reasons, the loans underlying these securities have had in
many cases higher default rates than those loans that meet government
underwriting requirements.

The risk of non-payment is greater for mortgage-backed securities that are
backed by mortgage pools that contain subprime loans, but a level of risk
exists for all loans. Market factors adversely affecting mortgage loan
repayments may include a general economic turndown, high unemployment, a
general slowdown in the real estate market, a drop in the market prices of real
estate, or an increase in interest rates resulting in higher mortgage payments
by holders of adjustable rate mortgages.

If the fund purchases subordinated mortgage-backed securities, the subordinated
mortgage-backed securities may serve as a credit support for the senior
securities purchased by other investors. In addition, the payments of principal
and interest on these subordinated securities generally will be made only after
payments are made to the holders of securities senior to the fund's securities.
Therefore, if there are defaults on the underlying mortgage loans, the fund
will be less likely to receive payments of principal and interest, and will be
more likely to suffer a loss.

Privately issued mortgage-backed securities are not traded on an exchange and
there may be a limited market for the securities, especially when there is a
perceived weakness in the mortgage and real estate market sectors. Without an
active trading market, mortgage-backed securities held in the portfolio may be
particularly difficult to value because of the complexities involved in
assessing the value of the underlying mortgage loans.

In the case of private issue mortgage-related securities whose underlying
assets are neither U.S. government securities nor U.S. government-insured
mortgages, to the extent that real properties securing such assets may be
located in the same geographical region, the security may be subject to a
greater risk of default than other comparable securities in the event of
adverse economic, political or business developments that may affect such
region and, ultimately, the ability of residential homeowners to make payments
of principal and interest on the underlying mortgages.

GUARANTEED MORTGAGE PASS-THROUGH SECURITIES. Guaranteed mortgage pass-through
securities represent participation interests in pools of residential mortgage
loans and are issued by U.S. governmental or private lenders and guaranteed by
the U.S. government or one of its agencies or instrumentalities, including but
not limited to GNMA, FNMA and FHLMC. GNMA certificates are guaranteed by the
full faith and credit of the U.S. government for timely payment of principal
and interest on the certificates. FNMA certificates are guaranteed by FNMA, a
federally chartered and privately owned corporation, for full and timely
payment of principal and interest on the certificates. FHLMC certificates are
guaranteed by FHLMC, a corporate instrumentality of the U.S. government, for
timely payment of interest and the ultimate collection of all principal of the
related mortgage loans.

Commercial banks, savings and loan institutions, private mortgage insurance
companies, mortgage bankers and other secondary market issuers also create
pass-through pools of conventional residential mortgage loans. Such issuers
may, in addition, be the originators and/or servicers of the underlying
mortgage loans as well as the guarantors of the mortgage-related securities.
Because there are no direct or indirect government or agency guarantees of
payments in pools created by such non-governmental issuers, they generally
offer a higher rate of interest than government and government-related pools.
Timely payment of interest and principal of these pools may be supported by
insurance or guarantees, including individual loan, title, pool


                                       5


and hazard insurance and letters of credit. The insurance and guarantees are
issued by governmental entities, private insurers and the mortgage poolers.
There can be no assurance that the private insurers or guarantors can meet
their obligations under the insurance policies or guarantee arrangements.

Mortgage-related securities without insurance or guarantees may be purchased if
Pioneer determines that the securities meet the fund's quality standards.
Mortgage-related securities issued by certain private organizations may not be
readily marketable.

MULTIPLE-CLASS PASS-THROUGH SECURITIES AND COLLATERALIZED MORTGAGE OBLIGATIONS
("CMOS"). CMOs and REMIC pass-through or participation certificates may be
issued by, among others, U.S. government agencies and instrumentalities as well
as private issuers. REMICs are CMO vehicles that qualify for special tax
treatment under the Internal Revenue Code of 1986, as amended (the "Code") and
invest in mortgages principally secured by interests in real property and other
investments permitted by the Code. CMOs and REMIC certificates are issued in
multiple classes and the principal of and interest on the mortgage assets may
be allocated among the several classes of CMOs or REMIC certificates in various
ways. Each class of CMO or REMIC certificate, often referred to as a "tranche,"
is issued at a specific adjustable or fixed interest rate and must be fully
retired no later than its final distribution date. Generally, interest is paid
or accrues on all classes of CMOs or REMIC certificates on a monthly basis.

Typically, CMOs are collateralized by GNMA, FNMA or FHLMC certificates but also
may be collateralized by other mortgage assets such as whole loans or private
mortgage pass-through securities. Debt service on CMOs is provided from
payments of principal and interest on collateral of mortgaged assets and any
reinvestment income thereon.

STRIPPED MORTGAGE-BACKED SECURITIES ("SMBS"). SMBS are multiple-class
mortgage-backed securities that are created when a U.S. government agency or a
financial institution separates the interest and principal components of a
mortgage-backed security and sells them as individual securities. The fund may
invest in SMBS that are usually structured with two classes that receive
different proportions of interest and principal distributions on a pool of
mortgage assets. A typical SMBS will have one class receiving some of the
interest and most of the principal, while the other class will receive most of
the interest and the remaining principal. The holder of the "principal-only"
security ("PO") receives the principal payments made by the underlying
mortgage-backed security, while the holder of the "interest-only" security
("IO") receives interest payments from the same underlying security. The prices
of stripped mortgage-backed securities may be particularly affected by changes
in interest rates. As interest rates fall, prepayment rates tend to increase,
which tends to reduce prices of IOs and increase prices of POs. Rising interest
rates can have the opposite effect. Pioneer may determine that certain stripped
mortgage-backed securities issued by the U.S. government, its agencies or
instrumentalities are not readily marketable. If so, these securities, together
with privately-issued stripped mortgage-backed securities, will be considered
illiquid for purposes of the fund's limitation on investments in illiquid
securities. The yields and market risk of interest-only and principal-only
SMBS, respectively, may be more volatile than those of other fixed income
securities.

The fund also may invest in planned amortization class ("PAC") and target
amortization class ("TAC") CMO bonds which involve less exposure to prepayment,
extension and interest rate risks than other mortgage-backed securities,
provided that prepayment rates remain within expected prepayment ranges or
"collars." To the extent that the prepayment rates remain within these
prepayment ranges, the residual or support tranches of PAC and TAC CMOs assume
the extra prepayment, extension and interest rate risks associated with the
underlying mortgage assets.

OTHER RISK FACTORS ASSOCIATED WITH MORTGAGE-BACKED SECURITIES. Investing in
mortgage-backed securities involves certain risks, including the failure of a
counterparty to meet its commitments, adverse interest rate changes and the
effects of prepayments on mortgage cash flows. In addition, investing in the
lowest tranche of CMOs and REMIC certificates involves risks similar to those
associated with investing in equity securities. However, due to adverse tax
consequences under current tax laws, the fund does not intend to acquire
"residual" interests in REMICs. Further, the yield characteristics of
mortgage-backed securities


                                       6


differ from those of traditional fixed income securities. The major differences
typically include more frequent interest and principal payments (usually
monthly), the adjustability of interest rates of the underlying instrument, and
the possibility that prepayments of principal may be made substantially earlier
than their final distribution dates.

Prepayment rates are influenced by changes in current interest rates and a
variety of economic, geographic, social and other factors and cannot be
predicted with certainty. Both adjustable rate mortgage loans and fixed rate
mortgage loans may be subject to a greater rate of principal prepayments in a
declining interest rate environment and to a lesser rate of principal
prepayments in an increasing interest rate environment. Under certain interest
rate and prepayment rate scenarios, the fund may fail to recoup fully its
investment in mortgage-backed securities notwithstanding any direct or indirect
governmental, agency or other guarantee. When the fund reinvests amounts
representing payments and unscheduled prepayments of principal, it may obtain a
rate of interest that is lower than the rate on existing adjustable rate
mortgage pass-through securities. Thus, mortgage-backed securities, and
adjustable rate mortgage pass-through securities in particular, may be less
effective than other types of U.S. government securities as a means of "locking
in" interest rates.


ASSET-BACKED SECURITIES
The fund may invest in asset-backed securities, which are securities that
represent a participation in, or are secured by and payable from, a stream of
payments generated by particular assets, most often a pool or pools of similar
assets (e.g., trade receivables). The credit quality of these securities
depends primarily upon the quality of the underlying assets and the level of
credit support and/or enhancement provided.

The underlying assets (e.g., loans) are subject to prepayments which shorten
the securities' weighted average maturity and may lower their return. If the
credit support or enhancement is exhausted, losses or delays in payment may
result if the required payments of principal and interest are not made. The
value of these securities also may change because of changes in the market's
perception of the creditworthiness of the servicing agent for the pool, the
originator of the pool, or the financial institution or trust providing the
credit support or enhancement. There may be no perfected security interest in
the collateral that relates to the financial assets that support asset-backed
securities. Asset backed securities have many of the same characteristics and
risks as mortgage-backed securities.

The fund may purchase commercial paper, including asset-backed commercial paper
("ABCP") that is issued by structured investment vehicles or other conduits.
These conduits may be sponsored by mortgage companies, investment banking
firms, finance companies, hedge funds, private equity firms and special purpose
finance entities. ABCP typically refers to a debt security with an original
term to maturity of up to 270 days, the payment of which is supported by cash
flows from underlying assets, or one or more liquidity or credit support
providers, or both. Assets backing ABCP include credit card, car loan and other
consumer receivables and home or commercial mortgages, including subprime
mortgages. The repayment of ABCP issued by a conduit depends primarily on the
cash collections received from the conduit's underlying asset portfolio and the
conduit's ability to issue new ABCP. Therefore, there could be losses to a fund
investing in ABCP in the event of credit or market value deterioration in the
conduit's underlying portfolio, mismatches in the timing of the cash flows of
the underlying asset interests and the repayment obligations of maturing ABCP,
or the conduit's inability to issue new ABCP. To protect investors from these
risks, ABCP programs may be structured with various protections, such as credit
enhancement, liquidity support, and commercial paper stop-issuance and
wind-down triggers. However there can be no guarantee that these protections
will be sufficient to prevent losses to investors in ABCP.

Some ABCP programs provide for an extension of the maturity date of the ABCP
if, on the related maturity date, the conduit is unable to access sufficient
liquidity through the issue of additional ABCP. This may delay the sale of the
underlying collateral and a fund may incur a loss if the value of the
collateral deteriorates during the extension period. Alternatively, if
collateral for ABCP deteriorates in value, the collateral may be required to be
sold at inopportune times or at prices insufficient to repay the principal and
interest on the


                                       7


ABCP. ABCP programs may provide for the issuance of subordinated notes as an
additional form of credit enhancement. The subordinated notes are typically of
a lower credit quality and have a higher risk of default. A fund purchasing
these subordinated notes will therefore have a higher likelihood of loss than
investors in the senior notes.

Asset-backed securities include collateralized debt obligations ("CDOs"), such
as collateralized bond obligations ("CBOs"), collateralized loan obligations
("CLOs") and other similarly structured securities. A CBO is a trust backed by
a pool of fixed income securities. A CLO is a trust typically collateralized by
a pool of loans, which may include, among others, domestic and foreign senior
secured loans, senior unsecured loans, and subordinate corporate loans,
including loans that may be rated below investment grade or equivalent unrated
loans. CDOs may charge management fees and administrative expenses. Certain
CDOs may use derivatives, such as credit default swaps, to create synthetic
exposure to assets rather than holding such assets directly.

The trust is typically split into two or more portions, called tranches,
varying in credit quality and yield. The riskiest portion is the "equity"
tranche which bears the bulk of defaults from the bonds or loans in the trust
and helps protect the other, more senior tranches from default. Since it is
partially protected from defaults, a senior tranche from a CBO trust or CLO
trust typically has higher ratings and lower yields than its underlying
securities, and can be rated investment grade. Despite the protection from the
equity tranche, CBO or CLO tranches can experience substantial losses due to
actual defaults, increased sensitivity to defaults due to collateral default
and the disappearance of protecting tranches, market anticipation of defaults,
as well as aversion to CBO or CLO securities as a class.

The risks of an investment in a CDO depend largely on the type of the
collateral securities and the class of the CDO in which the fund invests.
Normally, CBOs, CLOs and other CDOs are privately offered and sold, and thus
are not registered under the securities laws. As a result, investments in CDOs
may be characterized by the fund as illiquid securities. However, an active
dealer market may exist under some market conditions for some CDOs. In addition
to the normal risks associated with fixed income securities (e.g., interest
rate risk and default risk), CDOs carry additional risks including, but not
limited to: (i) the possibility that distributions from collateral securities
will not be adequate to make interest or other payments; (ii) the quality of
the collateral may decline in value or default; (iii) the fund may invest in
CDOs that are subordinate to other classes; and (iv) the complex structure of
the security may not be fully understood at the time of investment and may
produce disputes with the issuer or unexpected investment results.


SUBORDINATED SECURITIES
The fund may also invest in other types of fixed income securities which are
subordinated or "junior" to more senior securities of the issuer, or which
represent interests in pools of such subordinated or junior securities. Such
securities may include so-called "high yield" or "junk" bonds (i.e., bonds that
are rated below investment grade by a rating agency or that are of equivalent
quality) and preferred stock. Under the terms of subordinated securities,
payments that would otherwise be made to their holders may be required to be
made to the holders of more senior securities, and/or the subordinated or
junior securities may have junior liens, if they have any rights at all, in any
collateral (meaning proceeds of the collateral are required to be paid first to
the holders of more senior securities). As a result, subordinated or junior
securities will be disproportionately adversely affected by a default or even a
perceived decline in creditworthiness of the issuer.


STRUCTURED SECURITIES
The fund may invest in structured securities. The value of the principal and/or
interest on such securities is determined by reference to changes in the value
of specific currencies, interest rates, commodities, indices or other financial
indicators (the "Reference") or the relative change in two or more References.
The interest rate or the principal amount payable upon maturity or redemption
may be increased or decreased depending upon changes in the Reference. The
terms of the structured securities may provide in certain circumstances that no
principal is due at maturity and therefore may result in a loss of the fund's
investment.


                                       8


Changes in the interest rate or principal payable at maturity may be a multiple
of the changes in the value of the Reference. Structured securities are a type
of derivative instrument and the payment and credit qualities from these
securities derive from the assets embedded in the structure from which they are
issued. Structured securities may entail a greater degree of risk than other
types of fixed income securities.


FLOATING RATE LOANS
A floating rate loan is typically originated, negotiated and structured by a
U.S. or foreign commercial bank, insurance company, finance company or other
financial institution for a group of investors. The financial institution
typically acts as an agent for the investors, administering and enforcing the
loan on their behalf. In addition, an institution, typically but not always the
agent, holds any collateral on behalf of the investors.

The interest rates are adjusted based on a base rate plus a premium or spread
or minus a discount. The base rate usually is the London Interbank Offered Rate
("LIBOR"), the Federal Reserve federal funds rate, the prime rate or other base
lending rates used by commercial lenders. LIBOR usually is an average of the
interest rates quoted by several designated banks as the rates at which they
pay interest to major depositors in the London interbank market on U.S.
dollar-denominated deposits.

Floating rate loans include loans to corporations and institutionally traded
floating rate debt obligations issued by an asset-backed pool, and interests
therein. The fund may invest in loans in different ways. The fund may: (i) make
a direct investment in a loan by participating as one of the lenders; (ii)
purchase an assignment of a loan; or (iii) purchase a participation interest in
a loan.

DIRECT INVESTMENT IN LOANS. It can be advantageous to the fund to make a direct
investment in a loan as one of the lenders. When a new issue is purchased, such
an investment is typically made at par. This means that the fund receives a
return at the full interest rate for the loan. Secondary purchases of loans may
be made at par, at a premium from par or at a discount from par. When the fund
invests in an assignment of, or a participation interest in, a loan, the fund
may pay a fee or forgo a portion of the interest payment. Consequently, the
fund's return on such an investment may be lower than it would have been if the
fund had made a direct investment in the underlying corporate loan. The fund
may be able, however, to invest in corporate loans only through assignments or
participation interests at certain times when reduced direct investment
opportunities in corporate loans may exist. At other times, however, such as
recently, assignments or participation interests may trade at significant
discounts from par.

ASSIGNMENTS. An assignment represents a portion of a loan previously
attributable to a different lender. The purchaser of an assignment typically
succeeds to all the rights and obligations under the loan agreement of the
assigning investor and becomes an investor under the loan agreement with the
same rights and obligations as the assigning investor. Assignments may,
however, be arranged through private negotiations between potential assignees
and potential assignors, and the rights and obligations acquired by the
purchaser of an assignment may differ from, and be more limited than, those
held by the assigning investor.

PARTICIPATION INTERESTS. Participation interests are interests issued by a
lender or other financial institution, which represent a fractional interest in
a corporate loan. The fund may acquire participation interests from the
financial institution or from another investor. The fund typically will have a
contractual relationship only with the financial institution that issued the
participation interest. As a result, the fund may have the right to receive
payments of principal, interest and any fees to which it is entitled only from
the financial institution and only upon receipt by such entity of such payments
from the borrower. In connection with purchasing a participation interest, the
fund generally will have no right to enforce compliance by the borrower with
the terms of the loan agreement, nor any rights with respect to any funds
acquired by other investors through set-off against the borrower and the fund
may not directly benefit from the collateral supporting the loan in which it
has purchased the participation interest. As a result, the fund may assume the
credit risk of both the borrower and the financial institution issuing the
participation interest. In the event of the insolvency of the financial
institution issuing a participation interest, the fund may be treated as a
general creditor of such entity.


                                       9


OTHER INFORMATION ABOUT FLOATING RATE LOANS. Loans typically have a senior
position in a borrower's capital structure. The capital structure of a borrower
may include loans, senior unsecured loans, senior and junior subordinated debt,
preferred stock and common stock, typically in descending order of seniority
with respect to claims on the borrower's assets. Although loans typically have
the most senior position in a borrower's capital structure, they remain subject
to the risk of non-payment of scheduled interest or principal. Such non-payment
would result in a reduction of income to the fund, a reduction in the value of
the investment and a potential decrease in the net asset value of the fund.
There can be no assurance that the liquidation of any collateral securing a
loan would satisfy a borrower's obligation in the event of non-payment of
scheduled interest or principal payments, or that such collateral could be
readily liquidated. In the event of bankruptcy of a borrower, the fund could
experience delays or limitations with respect to its ability to realize the
benefits of the collateral securing a loan. Although a loan may be senior to
equity and other debt securities in an issuer's capital structure, such
obligations may be structurally subordinated to obligations of the issuer's
subsidiaries. For example, if a holding company were to issue a loan, even if
that issuer pledges the capital stock of its subsidiaries to secure the
obligations under the loan, the assets of the operating companies are available
to the direct creditors of an operating company before they would be available
to the holders of the loan issued by the holding company.

In order to borrow money pursuant to a loan, a borrower will frequently, for
the term of the loan, pledge collateral, including but not limited to, (i)
working capital assets, such as accounts receivable and inventory; (ii)
tangible fixed assets, such as real property, buildings and equipment; (iii)
intangible assets, such as trademarks and patent rights (but excluding
goodwill); and (iv) security interests in shares of stock of subsidiaries or
affiliates. In the case of loans made to non-public companies, the company's
shareholders or owners may provide collateral in the form of secured guarantees
and/or security interests in assets that they own. In many instances, a loan
may be secured only by stock in the borrower or its subsidiaries. Collateral
may consist of assets that may not be readily liquidated, and there is no
assurance that the liquidation of such assets would satisfy fully a borrower's
obligations under a loan.

In the process of buying, selling and holding loans, the fund may receive
and/or pay certain fees. Any fees received are in addition to interest payments
received and may include facility fees, commitment fees, commissions and
prepayment penalty fees. When the fund buys a loan it may receive a facility
fee and when it sells a loan it may pay a facility fee. On an ongoing basis,
the fund may receive a commitment fee based on the undrawn portion of the
underlying line of credit portion of a loan. In certain circumstances, the fund
may receive a prepayment penalty fee upon the prepayment of a loan by a
borrower. Other fees received by the fund may include covenant waiver fees and
covenant modification fees.

A borrower must comply with various restrictive covenants contained in a loan
agreement or note purchase agreement between the borrower and the holders of
the loan. Such covenants, in addition to requiring the scheduled payment of
interest and principal, may include restrictions on dividend payments and other
distributions to stockholders, provisions requiring the borrower to maintain
specific minimum financial ratios, and limits on total debt.

In a typical loan, the agent administers the terms of the loan agreement. In
such cases, the agent is normally responsible for the collection of principal
and interest payments from the borrower and the apportionment of these payments
to the credit of all institutions that are parties to the loan agreement. The
fund will generally rely upon the agent or an intermediate participant to
receive and forward to the fund its portion of the principal and interest
payments on the loan. Furthermore, unless the fund has direct recourse against
the borrower, the fund will rely on the agent and the other investors to use
appropriate credit remedies against the borrower.

For some loans, such as revolving credit facility loans ("revolvers"), an
investor may have certain obligations pursuant to the loan agreement that may
include the obligation to make additional loans in certain circumstances. The
fund generally will reserve against these contingent obligations by segregating
or otherwise designating a sufficient amount of permissible liquid assets.
Delayed draw term loans are similar to revolvers, except


                                       10


that once drawn upon by the borrower during the commitment period, they remain
permanently drawn and become term loans. A prefunded L/C term loan is a
facility created by the borrower in conjunction with an agent, with the loan
proceeds acting as collateral for the borrower's obligations in respect of the
letters of credit. Each participant in a prefunded L/C term loan fully funds
its commitment amount to the agent for the facility.

The fund may acquire interests in loans that are designed to provide temporary
or "bridge" financing to a borrower pending the sale of identified assets or
the arrangement of longer-term loans or the issuance and sale of debt
obligations. Bridge loans often are unrated. The fund may also invest in loans
of borrowers that have obtained bridge loans from other parties. A borrower's
use of bridge loans involves a risk that the borrower may be unable to locate
permanent financing to replace the bridge loan, which may impair the borrower's
perceived creditworthiness.

From time to time, Pioneer and its affiliates may borrow money from various
banks in connection with their business activities. Such banks may also sell
interests in loans to or acquire them from the fund or may be intermediate
participants with respect to loans in which the fund owns interests. Such banks
may also act as agents for loans held by the fund.


INVERSE FLOATING RATE SECURITIES
The fund may invest in inverse floating rate obligations. The interest on an
inverse floater resets in the opposite direction from the market rate of
interest to which the inverse floater is indexed. An inverse floater may be
considered to be leveraged to the extent that its interest rate varies by a
magnitude that exceeds the magnitude of the change in the index rate of
interest. The higher degree of leverage inherent in inverse floaters is
associated with greater volatility in their market values.


AUCTION RATE SECURITIES
The fund may invest in auction rate securities. Auction rate securities consist
of auction rate debt securities and auction rate preferred securities issued by
closed-end investment companies. Provided that the auction mechanism is
successful, auction rate securities usually permit the holder to sell the
securities in an auction at par value at specified intervals. The dividend is
reset by "Dutch" auction in which bids are made by broker-dealers and other
institutions for a certain amount of securities at a specified minimum yield.
The dividend rate set by the auction is the lowest interest or dividend rate
that covers all securities offered for sale. While this process is designed to
permit auction rate securities to be traded at par value, there is the risk
that an auction will fail due to insufficient demand for the securities. If an
auction fails, the dividend rate of the securities generally adjusts to a
maximum rate specified in the issuer's offering or charter documents. Security
holders that submit sell orders in a failed auction may not be able to sell any
or all of the shares for which they have submitted sell orders. Broker-dealers
may try to facilitate secondary trading in auction rate securities, although
such secondary trading may be limited and may only be available for
shareholders willing to sell at a discount. Since February 2008, nearly all
such auctions have failed, significantly affecting the liquidity of auction
rate securities. Holders of such securities have generally continued to receive
dividends at the above-mentioned maximum rate. There is no assurance that
auctions will resume or that any market will develop for auction rate
securities. Valuations of such securities are highly speculative. With respect
to auction rate securities issued by a closed-end fund, the fund will
indirectly bear its proportionate share of any management fees paid by the
closed-end fund in addition to the advisory fee payable directly by the fund.


EVENT-LINKED BONDS AND OTHER INSURANCE-LINKED SECURITIES
The fund may invest in "event-linked" bonds, which sometimes are referred to as
"insurance-linked" or "catastrophe" bonds. Event-linked bonds are debt
obligations for which the return of principal and the payment of interest are
contingent on the non-occurrence of a pre-defined "trigger" event, such as a
hurricane or an earthquake of a specific magnitude. For some event-linked
bonds, the trigger event's magnitude may be based on losses to a company or
industry, index-portfolio losses, industry indexes or readings of scientific
instruments rather than specified actual losses. If a trigger event, as defined
within the terms of an event-linked


                                       11


bond, involves losses or other metrics exceeding a specific magnitude in the
geographic region and time period specified therein, the fund may lose a
portion or all of its accrued interest and/or principal invested in such
event-linked bond. The fund is entitled to receive principal and interest
payments so long as no trigger event occurs of the description and magnitude
specified by the instrument.

Event-linked bonds may be issued by government agencies, insurance companies,
reinsurers, special purpose corporations or other on-shore or off-shore
entities. In addition to the specified trigger events, event-linked bonds may
also expose the fund to other risks, including but not limited to issuer
(credit) default, adverse regulatory or jurisdictional interpretations and
adverse tax consequences. Event-linked bonds are subject to the risk that the
model used to calculate the probability of a trigger event was not accurate and
underestimated the likelihood of a trigger event. This may result in more
frequent and greater than expected loss of principal and/or interest, which
would adversely impact the fund's total returns. Further, to the extent there
are events that involve losses or other metrics, as applicable, that are at, or
near, the threshold for a trigger event, there may be some delay in the return
of principal and/or interest until it is determined whether a trigger event has
occurred. Finally, to the extent there is a dispute concerning the definition
of the trigger event relative to the specific manifestation of a catastrophe,
there may be losses or delays in the payment of principal and/or interest on
the event-linked bond. Lack of a liquid market for these instruments may impose
the risk of higher transactions costs and the possibility that the fund may be
forced to liquidate positions when it would not be advantageous to do so.

Event-linked bonds are typically rated by at least one nationally recognized
rating agency, but also may be unrated. Although each rating agency utilizes
its own general guidelines and methodology to evaluate the risks of an
event-linked bond, the average rating in the current market for event-linked
bonds is "BB" by Standard & Poor's Rating Group (or the equivalent rating for
another rating agency). However, there are event-linked bonds rated higher or
lower than "BB." Securities rated BB or lower are considered to be below
investment grade.

The fund's investments in event-linked bonds generally will be rated B, BB or
BBB at the time of purchase, although the fund may invest in event-linked bonds
rated higher or lower than these ratings, as well as event-linked bonds that
are unrated. The rating for an event-linked bond primarily reflects the rating
agency's calculated probability that a pre-defined trigger event will occur.
This rating also assesses the bond's credit risk and model used to calculate
the probability of the trigger event.

In addition to event-linked bonds, the fund also may invest in other
insurance-linked securities, including notes or preferred shares issued by
special purpose vehicles structured to comprise a portion of an reinsurer's or
insurer's catastrophe-oriented business, known as sidecars, or to provide
reinsurance to reinsurers or insurers, known as collateralized reinsurance
("Reinsurance Notes"). An investor in Reinsurance Notes participates in the
premiums and losses associated with underlying reinsurance contracts.
Reinsurance Notes are subject to the same risks discussed herein for
event-linked bonds. In addition, because Reinsurance Notes represent an
interest in underlying reinsurance contracts, the fund has limited transparency
into the underlying insurance policies and therefore must rely upon the risk
assessment and sound underwriting practices of the reinsurer and/or insurer.
Accordingly, it may be more difficult for the investment adviser to fully
evaluate the underlying risk profile of the fund's investment in Reinsurance
Notes and therefore place the fund's assets at greater risk of loss than if the
adviser had more complete information. The lack of transparency may also make
the valuation of Reinsurance Notes more difficult and potentially result in
mispricing that could result in losses to the fund. Reinsurance Notes are also
subject to extension risk. The sponsor of such an investment might have the
right to extend the maturity of the notes to verify that the trigger event did
occur or to process and audit insurance claims. In certain circumstances, the
extension may exceed two years.

Event-linked bonds and other insurance-linked securities typically are
restricted to qualified institutional buyers and, therefore, are not subject to
registration with the Securities and Exchange Commission or any state
securities commission and are not listed on any national securities exchange.
The amount of public


                                       12


information available with respect to event-linked bonds and other
insurance-linked securities is generally less extensive than that available for
issuers of registered or exchange listed securities. Event-linked bonds may be
subject to the risks of adverse regulatory or jurisdictional determinations.
There can be no assurance that future regulatory determinations will not
adversely affect the overall market for event-linked bonds.


EVENT-LINKED SWAPS
The fund may obtain event-linked exposure by investing in event-linked swaps,
which typically are contingent, or formulaically related to defined trigger
events, or by pursuing similar event-linked derivative strategies. Trigger
events include hurricanes, earthquakes and weather-related phenomena. If a
trigger event occurs, the fund may lose the swap's notional amount. As
derivative instruments, event-linked swaps are subject to risks in addition to
the risks of investing in event-linked bonds, including counterparty risk and
leverage risk.


ZERO COUPON, PAY-IN-KIND, DEFERRED AND CONTINGENT PAYMENT SECURITIES
The fund may invest in zero coupon securities, which are securities that are
sold at a discount to par value and on which interest payments are not made
during the life of the security. Upon maturity, the holder is entitled to
receive the par value of the security. Pay-in-kind securities are securities
that have interest payable by delivery of additional securities. Upon maturity,
the holder is entitled to receive the aggregate par value of the securities. A
fund accrues income with respect to zero coupon and pay-in-kind securities
prior to the receipt of cash payments. Deferred payment securities are
securities that remain zero coupon securities until a predetermined date, at
which time the stated coupon rate becomes effective and interest becomes
payable at regular intervals. The interest rate on contingent payment
securities is determined by the outcome of an event, such as the performance of
a financial index. If the financial index does not increase by a prescribed
amount, the fund may receive no interest.


EQUITY SECURITIES AND RELATED INVESTMENTS


INVESTMENTS IN EQUITY SECURITIES
Equity securities, such as common stock, generally represent an ownership
interest in a company. While equity securities have historically generated
higher average returns than fixed income securities, equity securities have
also experienced significantly more volatility in those returns. An adverse
event, such as an unfavorable earnings report, may depress the value of a
particular equity security held by the fund. Also, the prices of equity
securities, particularly common stocks, are sensitive to general movements in
the stock market. A drop in the stock market may depress the price of equity
securities held by the fund.


WARRANTS AND STOCK PURCHASE RIGHTS
The fund may invest in warrants, which are securities permitting, but not
obligating, their holder to subscribe for other securities. Warrants do not
carry with them the right to dividends or voting rights with respect to the
securities that they entitle their holders to purchase, and they do not
represent any rights in the assets of the issuer.

The fund may also invest in stock purchase rights. Stock purchase rights are
instruments, frequently distributed to an issuer's shareholders as a dividend,
that entitle the holder to purchase a specific number of shares of common stock
on a specific date or during a specific period of time. The exercise price on
the rights is normally at a discount from market value of the common stock at
the time of distribution. The rights do not carry with them the right to
dividends or to vote and may or may not be transferable. Stock purchase rights
are frequently used outside of the United States as a means of raising
additional capital from an issuer's current shareholders.

As a result, an investment in warrants or stock purchase rights may be
considered more speculative than certain other types of investments. In
addition, the value of a warrant or a stock purchase right does not necessarily
change with the value of the underlying securities, and warrants and stock
purchase rights expire worthless if they are not exercised on or prior to their
expiration date.


                                       13


PREFERRED SHARES
The fund may invest in preferred shares. Preferred shares are equity
securities, but they have many characteristics of fixed income securities, such
as a fixed dividend payment rate and/or a liquidity preference over the
issuer's common shares. However, because preferred shares are equity
securities, they may be more susceptible to risks traditionally associated with
equity investments than the fund's fixed income securities.

Preferred stocks may differ in many of their provisions. Among the features
that differentiate preferred stocks from one another are the dividend rights,
which may be cumulative or noncumulative and participating or
non-participating, redemption provisions, and voting rights. Such features will
establish the income return and may affect the prospects for capital
appreciation or risks of capital loss.

The market prices of preferred stocks are subject to changes in interest rates
and are more sensitive to changes in an issuer's creditworthiness than are the
prices of debt securities. Shareholders of preferred stock may suffer a loss of
value if dividends are not paid. Under ordinary circumstances, preferred stock
does not carry voting rights.


NON-U.S. INVESTMENTS


EQUITY SECURITIES OF NON-U.S. ISSUERS
The fund may invest in equity securities of non-U.S. issuers, including
American Depositary Receipts ("ADRs"), European Depositary Receipts ("EDRs"),
Global Depositary Receipts ("GDRs") and other similar instruments.


DEBT OBLIGATIONS OF NON-U.S. GOVERNMENTS
The fund may invest in all types of debt obligations of non-U.S. governments.
An investment in debt obligations of non-U.S. governments and their political
subdivisions (sovereign debt) involves special risks that are not present in
corporate debt obligations. The non-U.S. issuer of the sovereign debt or the
non-U.S. governmental authorities that control the repayment of the debt may be
unable or unwilling to repay principal or interest when due, and the fund may
have limited recourse in the event of a default. As a sovereign entity, the
issuing government may be immune from lawsuits in the event of its failure or
refusal to pay the obligations when due. During periods of economic uncertainty
(such as the financial crisis that began in 2008), the values of sovereign debt
and of securities of issuers that purchase sovereign debt may be more volatile
than prices of debt obligations of U.S. issuers. In the past, certain non-U.S.
countries have encountered difficulties in servicing their debt obligations,
withheld payments of principal and interest, declared moratoria on the payment
of principal and interest on their sovereign debt, or restructured their debt
to effectively eliminate portions of it, and similar occurrences may happen in
the future. There is no bankruptcy proceeding by which sovereign debt on which
governmental entities have defaulted may be collected in whole or in part.

A sovereign debtor's willingness or ability to repay principal and pay interest
in a timely manner may be affected by, among other factors, its cash flow
situation, the extent of its foreign currency reserves, the availability of
sufficient foreign exchange, the relative size of the debt service burden, the
sovereign debtor's policy toward its principal international lenders and local
political constraints. Sovereign debtors may also be dependent on disbursements
or assistance from non-U.S. governments, multinational agencies and other
entities to reduce principal and interest arrearages on their debt. Assistance
may be dependent on a country's implementation of austerity measures and
reforms, which measures may limit or be perceived to limit economic growth and
recovery. The failure of a sovereign debtor to implement economic reforms,
achieve specified levels of economic performance or repay principal or interest
when due may result in the cancellation of third-party commitments to lend
funds to the sovereign debtor, which may further impair such debtor's ability
or willingness to service its debts.

EURODOLLAR INSTRUMENTS AND SAMURAI AND YANKEE BONDS. The fund may invest in
Eurodollar instruments and Samurai and Yankee bonds. Eurodollar instruments are
bonds of corporate and government issuers that pay interest and principal in
U.S. dollars but are issued in markets outside the United States, primarily in
Europe. Samurai bonds are yen-denominated bonds sold in Japan by non-Japanese
issuers. Yankee


                                       14


bonds are U.S. dollar denominated bonds typically issued in the U.S. by
non-U.S. governments and their agencies and non-U.S. banks and corporations.
The fund may also invest in Eurodollar Certificates of Deposit ("ECDs"),
Eurodollar Time Deposits ("ETDs") and Yankee Certificates of Deposit ("Yankee
CDs"). ECDs are U.S. dollar-denominated certificates of deposit issued by
non-U.S. branches of domestic banks; ETDs are U.S. dollar-denominated deposits
in a non-U.S. branch of a U.S. bank or in a non-U.S. bank; and Yankee CDs are
U.S. dollar-denominated certificates of deposit issued by a U.S. branch of a
non-U.S. bank and held in the U.S. These investments involve risks that are
different from investments in securities issued by U.S. issuers, including
potential unfavorable political and economic developments, non-U.S. withholding
or other taxes, seizure of non-U.S. deposits, currency controls, interest
limitations or other governmental restrictions which might affect payment of
principal or interest.

INVESTMENTS IN EMERGING MARKETS. The fund may invest in securities of issuers
in countries with emerging economies or securities markets. Emerging economies
or securities markets will generally include, but not be limited to, countries
included in the Morgan Stanley Capital International (MSCI) Emerging & Frontier
Markets Index. The fund will generally focus on emerging markets that do not
impose unusual trading requirements which tend to restrict the flow of
investments. In addition, the fund may invest in unquoted securities of
emerging market issuers.

RISKS OF NON-U.S. INVESTMENTS. Investing in securities of non-U.S. issuers
involves considerations and risks not typically associated with investing in
the securities of issuers in the U.S. These risks are heightened with respect
to investments in countries with emerging markets and economies. The risks of
investing in securities of non-U.S. issuers generally, or in issuers with
significant exposure to non-U.S. markets, may be related, among other things,
to (i) differences in size, liquidity and volatility of, and the degree and
manner of regulation of, the securities markets of certain non-U.S. markets
compared to the securities markets in the U.S.; (ii) economic, political and
social factors; and (iii) foreign exchange matters, such as restrictions on the
repatriation of capital, fluctuations in exchange rates between the U.S. dollar
and the currencies in which the portfolio securities are quoted or denominated,
exchange control regulations and costs associated with currency exchange. The
political and economic structures in certain countries, particularly emerging
markets, may undergo significant evolution and rapid development, and such
countries may lack the social, political and economic stability characteristic
of more developed countries.

NON-U.S. SECURITIES MARKETS AND REGULATIONS. There may be less publicly
available information about non-U.S. markets and issuers than is available with
respect to U.S. securities and issuers. Non-U.S. companies generally are not
subject to accounting, auditing and financial reporting standards, practices
and requirements comparable to those applicable to U.S. companies. The trading
markets for most non-U.S. securities are generally less liquid and subject to
greater price volatility than the markets for comparable securities in the U.S.
The markets for securities in certain emerging markets are in the earliest
stages of their development. Even the markets for relatively widely traded
securities in certain non-U.S. markets, including emerging market countries,
may not be able to absorb, without price disruptions, a significant increase in
trading volume or trades of a size customarily undertaken by institutional
investors in the U.S. Additionally, market making and arbitrage activities are
generally less extensive in such markets, which may contribute to increased
volatility and reduced liquidity. The less liquid a market, the more difficult
it may be for the fund to accurately price its portfolio securities or to
dispose of such securities at the times determined by Pioneer to be
appropriate. The risks associated with reduced liquidity may be particularly
acute in situations in which the fund's operations require cash, such as in
order to meet redemptions and to pay its expenses.

ECONOMIC, POLITICAL AND SOCIAL FACTORS. Certain countries, including emerging
markets, may be subject to a greater degree of economic, political and social
instability than in the U.S. and Western European countries. Such instability
may result from, among other things: (i) authoritarian governments or military
involvement in political and economic decision making; (ii) popular unrest
associated with demands for improved economic, political and social conditions;
(iii) internal insurgencies; (iv) hostile relations with neighboring countries;
and (v) ethnic, religious and racial conflict. Such economic, political and
social instability could significantly disrupt the financial markets in such
countries and the ability of the issuers in


                                       15


such countries to repay their obligations. In addition, it may be difficult for
the fund to pursue claims against a foreign issuer in the courts of a foreign
country. Investing in emerging market countries also involves the risk of
expropriation, nationalization, confiscation of assets and property or the
imposition of restrictions on foreign investments and on repatriation of
capital invested. In the event of such expropriation, nationalization or other
confiscation in any emerging country, the fund could lose its entire investment
in that country.

Investments that have exposure to Russian or Ukrainian issuers or markets may
be significantly affected by recent events in those regions and economic
sanctions against Russia and other responses to these events by the United
States and other nations.

Certain emerging market countries restrict or control foreign investment in
their securities markets to varying degrees. These restrictions may limit the
fund's investment in those markets and may increase the expenses of the fund.
In addition, the repatriation of both investment income and capital from
certain markets is subject to restrictions such as the need for certain
governmental consents. Even where there is no outright restriction on
repatriation of capital, the mechanics of repatriation may affect certain
aspects of the fund's operation.

Economies in individual countries may differ favorably or unfavorably from the
U.S. economy in such respects as growth of gross domestic product, rates of
inflation, currency valuation, capital reinvestment, resource self-sufficiency
and balance of payments positions. Many countries have experienced substantial,
and in some cases extremely high, rates of inflation for many years. Inflation
and rapid fluctuations in inflation rates have had, and may continue to have,
very negative effects on the economies and securities markets of certain
emerging countries.

Unanticipated political or social developments may affect the values of the
fund's investments and the availability to the fund of additional investments
in such countries. In the past, the economies, securities and currency markets
of many emerging markets have experienced significant disruption and declines.
There can be no assurance that these economic and market disruptions might not
occur again.

Economies in emerging market countries generally are dependent heavily upon
international trade and, accordingly, have been and may continue to be affected
adversely by trade barriers, exchange controls, managed adjustments in relative
currency values and other protectionist measures imposed or negotiated by the
countries with which they trade. These economies also have been, and may
continue to be, affected adversely and significantly by economic conditions in
the countries with which they trade.

Some countries in Europe have experienced severe economic and financial
difficulties. Many non-governmental issuers, and even certain governments, have
defaulted on, or been forced to restructure, their debts; many other issuers
have faced difficulties obtaining credit or refinancing existing obligations;
financial institutions have in many cases required government or central bank
support, have needed to raise capital, and/or have been impaired in their
ability to extend credit; and financial markets in Europe and elsewhere have
experienced extreme volatility and declines in asset values and liquidity.
These difficulties may continue, worsen or spread within and beyond Europe.
Responses to the financial problems by European governments, central banks and
others, including austerity measures and reforms, may not work, may result in
social unrest and may limit future growth and economic recovery or have other
unintended consequences. Further defaults or restructurings by governments and
others of their debt could have additional adverse effects on economies,
financial markets and asset valuations around the world. In addition, one or
more countries may abandon the euro, the common currency of the European Union,
and/or withdraw from the European Union. The impact of these actions,
especially if they occur in a disorderly fashion, is not clear but could be
significant and far-reaching. Whether or not the fund invests in securities of
issuers located in Europe or with significant exposure to European issuers or
countries, these events could negatively affect the value and liquidity of the
fund's investments due to the interconnected nature of the global economy and
capital markets.


                                       16


CURRENCY RISKS. The value of the securities quoted or denominated in foreign
currencies may be adversely affected by fluctuations in the relative currency
exchange rates and by exchange control regulations. The fund 's investment
performance may be negatively affected by a devaluation of a currency in which
the fund's investments are quoted or denominated. Further, the fund's
investment performance may be significantly affected, either positively or
negatively, by currency exchange rates because the U.S. dollar value of
securities quoted or denominated in another currency will increase or decrease
in response to changes in the value of such currency in relation to the U.S.
dollar.

CUSTODIAN SERVICES AND RELATED INVESTMENT COSTS. Custodial services and other
costs relating to investment in international securities markets generally are
more expensive than in the U.S. Such markets have settlement and clearance
procedures that differ from those in the U.S. In certain markets there have
been times when settlements have been unable to keep pace with the volume of
securities transactions, making it difficult to conduct such transactions. The
inability of the fund to make intended securities purchases due to settlement
problems could cause the fund to miss attractive investment opportunities.
Inability to dispose of a portfolio security caused by settlement problems
could result either in losses to the fund due to a subsequent decline in value
of the portfolio security or could result in possible liability to the fund. In
addition, security settlement and clearance procedures in some emerging
countries may not fully protect the fund against loss or theft of its assets.

WITHHOLDING AND OTHER TAXES. The fund may be subject to taxes, including
withholding taxes, on income (possibly including, in some cases, capital gains)
that are or may be imposed by certain countries with respect to the fund's
investments in such countries. These taxes may reduce the return achieved by
the fund. Treaties between the U.S. and such countries may not be available to
reduce the otherwise applicable tax rates.


INVESTMENTS IN DEPOSITARY RECEIPTS
The fund may hold securities of non-U.S. issuers in the form of ADRs, EDRs,
GDRs and other similar instruments. Generally, ADRs in registered form are
designed for use in U.S. securities markets, and EDRs and GDRs and other
similar global instruments in bearer form are designed for use in non-U.S.
securities markets.

ADRs are denominated in U.S. dollars and represent an interest in the right to
receive securities of non-U.S. issuers deposited in a U.S. bank or
correspondent bank. ADRs do not eliminate all the risk inherent in investing in
the securities of non-U.S. issuers. However, by investing in ADRs rather than
directly in equity securities of non-U.S. issuers, the fund will avoid currency
risks during the settlement period for either purchases or sales. EDRs and GDRs
are not necessarily denominated in the same currency as the underlying
securities which they represent.

For purposes of the fund's investment policies, investments in ADRs, EDRs, GDRs
and similar instruments will be deemed to be investments in the underlying
equity securities of non-U.S. issuers. The fund may acquire depositary receipts
from banks that do not have a contractual relationship with the issuer of the
security underlying the depositary receipt to issue and secure such depositary
receipt. To the extent the fund invests in such unsponsored depositary receipts
there may be an increased possibility that the fund may not become aware of
events affecting the underlying security and thus the value of the related
depositary receipt. In addition, certain benefits (i.e., rights offerings)
which may be associated with the security underlying the depositary receipt may
not inure to the benefit of the holder of such depositary receipt.


FOREIGN CURRENCY TRANSACTIONS
The fund may engage in foreign currency transactions. These transactions may be
conducted at the prevailing spot rate for purchasing or selling currency in the
foreign exchange market. The fund also may enter into forward foreign currency
exchange contracts, which are contractual agreements to purchase or sell a
specified currency at a specified future date and price set at the time of the
contract.


                                       17


The fund may enter into forward foreign currency exchange contracts involving
currencies of the different countries in which the fund invests as a hedge
against possible variations in the foreign exchange rates between these
currencies and the U.S. dollar. Transaction hedging is the purchase or sale of
forward foreign currency contracts with respect to specific receivables or
payables of the fund, accrued in connection with the purchase and sale of its
portfolio securities quoted in foreign currencies. Portfolio hedging is the use
of forward foreign currency contracts to offset portfolio security positions
denominated or quoted in such foreign currencies. There is no guarantee that
the fund will be engaged in hedging activities when adverse exchange rate
movements occur or that its hedging activities will be successful. The fund
will not attempt to hedge all of its foreign portfolio positions and will enter
into such transactions only to the extent, if any, deemed appropriate by
Pioneer.

Hedging against a decline in the value of a currency does not eliminate
fluctuations in the prices of portfolio securities or prevent losses if the
prices of such securities decline. Such transactions also limit the opportunity
for gain if the value of the hedged currency should rise. Moreover, it may not
be possible for the fund to hedge against a devaluation that is so generally
anticipated that the fund is not able to contract to sell the currency at a
price above the devaluation level it anticipates.

The fund may also engage in cross-hedging by using forward contracts in one
currency to hedge against fluctuations in the value of securities denominated
in a different currency, if Pioneer determines that there is a pattern of
correlation between the two currencies. Cross-hedging may also include entering
into a forward transaction involving two foreign currencies, using one foreign
currency as a proxy for the U.S. dollar to hedge against variations in the
other foreign currency.

The fund may use forward currency exchange contracts to reduce or gain exposure
to a currency. To the extent the fund gains exposure to a currency through
these instruments, the resulting exposure may exceed the value of securities
denominated in that currency held by the fund. For example, where the fund's
security selection has resulted in an overweight or underweight exposure to a
particular currency relative to the fund's benchmark, the fund may seek to
adjust currency exposure using forward currency exchange contracts.

The cost to the fund of engaging in foreign currency transactions varies with
such factors as the currency involved, the size of the contract, the length of
the contract period, differences in interest rates between the two currencies
and the market conditions then prevailing. Since transactions in foreign
currency and forward contracts are usually conducted on a principal basis, no
fees or commissions are involved. The fund may close out a forward position in
a currency by selling the forward contract or by entering into an offsetting
forward contract.

The precise matching of the forward contract amounts and the value of the
securities involved will not generally be possible because the future value of
such securities in foreign currencies will change as a consequence of market
movements in the value of those securities between the date on which the
contract is entered into and the date it matures. Using forward contracts to
protect the value of the portfolio securities against a decline in the value of
a currency does not eliminate fluctuations in the underlying prices of the
securities. It simply establishes a rate of exchange which the fund can achieve
at some future point in time. The precise projection of currency market
movements is not possible, and short-term hedging provides a means of fixing
the U.S. dollar value of only a portion of the fund's foreign assets.

While the fund may benefit from foreign currency transactions, unanticipated
changes in currency prices may result in a poorer overall performance for the
fund than if it had not engaged in any such transactions. Moreover, there may
be imperfect correlation between the portfolio holdings of securities quoted or
denominated in a particular currency and forward contracts entered into by the
fund. Such imperfect correlation may cause the fund to sustain losses which
will prevent the fund from achieving a complete hedge or expose the fund to
risk of foreign exchange loss.


                                       18


Over-the-counter markets for trading foreign forward currency contracts offer
less protection against defaults than is available when trading in currency
instruments on an exchange. Since a forward foreign currency exchange contract
is not guaranteed by an exchange or clearinghouse, a default on the contract
would deprive the fund of unrealized profits or force the fund to cover its
commitments for purchase or resale, if any, at the current market price.

If the fund enters into a forward contract to purchase foreign currency, the
custodian or Pioneer will segregate liquid assets. See "Asset Segregation."


OPTIONS ON FOREIGN CURRENCIES
The fund may purchase options on foreign currencies for hedging purposes in a
manner similar to that of transactions in forward contracts. For example, a
decline in the dollar value of a foreign currency in which portfolio securities
are quoted or denominated will reduce the dollar value of such securities, even
if their value in the foreign currency remains constant. In an attempt to
protect against such decreases in the value of portfolio securities, the fund
may purchase put options on the foreign currency. If the value of the currency
declines, the fund will have the right to sell such currency for a fixed amount
of dollars which exceeds the market value of such currency. This would result
in a gain that may offset, in whole or in part, the negative effect of currency
depreciation on the value of the fund's securities quoted or denominated in
that currency.

Conversely, if a rise in the dollar value of a currency is projected for those
securities to be acquired, thereby increasing the cost of such securities, the
fund may purchase call options on such currency. If the value of such currency
increases, the purchase of such call options would enable the fund to purchase
currency for a fixed amount of dollars which is less than the market value of
such currency. Such a purchase would result in a gain that may offset, at least
partially, the effect of any currency-related increase in the price of
securities the fund intends to acquire. As in the case of other types of
options transactions, however, the benefit the fund derives from purchasing
foreign currency options will be reduced by the amount of the premium and
related transaction costs. In addition, if currency exchange rates do not move
in the direction or to the extent anticipated, the fund could sustain losses on
transactions in foreign currency options which would deprive it of a portion or
all of the benefits of advantageous changes in such rates.

The fund may also write options on foreign currencies for hedging purposes. For
example, if the fund anticipated a decline in the dollar value of securities
quoted or denominated in a foreign currency because of declining exchange
rates, it could, instead of purchasing a put option, write a covered call
option on the relevant currency. If the expected decline occurs, the option
will most likely not be exercised, and the decrease in value of portfolio
securities will be partially offset by the amount of the premium received by
the fund.

Similarly, the fund could write a put option on the relevant currency, instead
of purchasing a call option, to hedge against an anticipated increase in the
dollar cost of securities to be acquired. If exchange rates move in the manner
projected, the put option will expire unexercised and allow the fund to offset
such increased cost up to the amount of the premium. However, as in the case of
other types of options transactions, the writing of a foreign currency option
will constitute only a partial hedge up to the amount of the premium, and only
if rates move in the expected direction. If unanticipated exchange rate
fluctuations occur, the option may be exercised and the fund would be required
to purchase or sell the underlying currency at a loss, which may not be fully
offset by the amount of the premium. As a result of writing options on foreign
currencies, the fund also may be required to forgo all or a portion of the
benefits which might otherwise have been obtained from favorable movements in
currency exchange rates.

A call option written on foreign currency by the fund is "covered" if the fund
owns the underlying foreign currency subject to the call, or if it has an
absolute and immediate right to acquire that foreign currency without
additional cash consideration. A call option is also covered if the fund holds
a call on the same


                                       19


foreign currency for the same principal amount as the call written where the
exercise price of the call held is (a) equal to or less than the exercise price
of the call written or (b) greater than the exercise price of the call written
if the amount of the difference is maintained by the fund in cash or liquid
securities. See "Asset Segregation."

The fund may close out its position in a currency option by either selling the
option it has purchased or entering into an offsetting option. An
exchange-traded options position may be closed out only on an options exchange
which provides a secondary market for an option of the same series. Although
the fund will generally purchase or write only those options for which there
appears to be an active secondary market, there is no assurance that a liquid
secondary market on an exchange will exist for any particular option, or at any
particular time. For some options no secondary market on an exchange may exist.
In such event, it might not be possible to effect closing transactions in
particular options, with the result that the fund would have to exercise its
options in order to realize any profit and would incur transaction costs upon
the sale of underlying currencies pursuant to the exercise of put options. If
the fund as a covered call option writer is unable to effect a closing purchase
transaction in a secondary market, it will not be able to sell the underlying
currency (or security quoted or denominated in that currency) until the option
expires or it delivers the underlying currency upon exercise.

The fund may also use options on currencies to cross-hedge, which involves
writing or purchasing options on one currency to hedge against changes in
exchange rates of a different currency with a pattern of correlation.
Cross-hedging may also include using a foreign currency as a proxy for the U.S.
dollar, if Pioneer determines that there is a pattern of correlation between
that currency and the U.S. dollar.

The fund may purchase and write over-the-counter options. Trading in
over-the-counter options is subject to the risk that the other party will be
unable or unwilling to close out options purchased or written by the fund.


NATURAL DISASTERS
Certain areas of the world, including areas within the United States,
historically have been prone to natural disasters, such as hurricanes,
earthquakes, typhoons, flooding, tidal waves, tsunamis, erupting volcanoes,
wildfires or droughts. Such disasters, and the resulting damage, could have a
significant adverse impact on the economies of those areas and on the ability
of issuers in which the fund invests to conduct their businesses, and thus on
the investments made by the fund in such geographic areas and/or issuers.
Adverse weather conditions could have a significant adverse impact on issuers
in the agricultural sector and on insurance companies that insure against the
impact of natural disasters.


CYBERSECURITY ISSUES
With the increased use of technologies such as the Internet to conduct
business, the fund is susceptible to operational, information security and
related risks. In general, cyber incidents can result from deliberate attacks
or unintentional events. Cyber attacks include, but are not limited to, gaining
unauthorized access to digital systems (e.g., through "hacking" or malicious
software coding) for purposes of misappropriating assets or sensitive
information, corrupting data, or causing operational disruption. Cyber attacks
may also be carried out in a manner that does not require gaining unauthorized
access, such as causing denial-of-service attacks on websites (i.e., efforts to
make network services unavailable to intended users). Cybersecurity failures or
breaches by the fund's adviser, transfer agent, distributor and other service
providers (including, but not limited to, the fund's custodian and financial
intermediaries), and the issuers of securities in which the fund invests, have
the ability to cause disruptions and impact business operations potentially
resulting in financial losses, interference with the fund's ability to
calculate its NAV, impediments to trading, the inability of fund shareholders
to transact business, violations of applicable privacy and other laws,
regulatory fines, penalties, reputational damage, reimbursement or other
compensation costs, or additional compliance costs. In addition, substantial
costs may be incurred in order to prevent any cyber incidents in the future.
While the fund or its adviser has established business continuity plans in the
event of, and risk management systems to prevent, such cyber attacks, there are
inherent limitations in such plans and systems including


                                       20


the possibility that certain risks have not been identified. Furthermore, the
fund cannot control the cyber security plans and systems put in place by
service providers to the fund and issuers in which the fund invests. The fund
and its shareholders could be negatively impacted as a result.


INVESTMENT COMPANY SECURITIES AND REAL ESTATE INVESTMENT TRUSTS


OTHER INVESTMENT COMPANIES
The fund may invest in the securities of other investment companies to the
extent that such investments are consistent with the fund's investment
objectives and policies and permissible under the Investment Company Act of
1940, as amended (the "1940 Act") and the rules thereunder. Investing in other
investment companies subjects the fund to the risks of investing in the
underlying securities held by those investment companies. The fund, as a holder
of the securities of other investment companies, will bear its pro rata portion
of the other investment companies' expenses, including advisory fees. These
expenses are in addition to the direct expenses of the fund's own operations.


EXCHANGE TRADED FUNDS
The fund may invest in exchange traded funds ("ETFs"). ETFs, such as SPDRs,
iShares and various country index funds, are funds whose shares are traded on a
national exchange or the National Association of Securities Dealers' Automated
Quotation System ("NASDAQ"). ETFs may be based on underlying equity or fixed
income securities. SPDRs, for example, seek to provide investment results that
generally correspond to the performance of the component common stocks of the
Standard & Poor's 500 Stock Index (the "S&P 500"). ETFs do not sell individual
shares directly to investors and only issue their shares in large blocks known
as "creation units." The investor purchasing a creation unit then sells the
individual shares on a secondary market. Therefore, the liquidity of ETFs
depends on the adequacy of the secondary market. There can be no assurance that
an ETF's investment objective will be achieved. ETFs based on an index may not
replicate and maintain exactly the composition and relative weightings of
securities in the index. ETFs are subject to the risks of investing in the
underlying securities. The fund, as a holder of the securities of the ETF, will
bear its pro rata portion of the ETF's expenses, including advisory fees. These
expenses are in addition to the direct expenses of the fund's own operations.
Many ETFs have received exemptive orders issued by the Securities and Exchange
Commission that would permit the fund to invest in those ETFs beyond the
limitations applicable to other investment companies, subject to certain terms
and conditions. Some ETFs are not structured as investment companies and thus
are not regulated under the 1940 Act.

Certain ETFs, including leveraged ETFs and inverse ETFs, may have embedded
leverage. Leveraged ETFs seek to multiply the return of the tracked index
(e.g., twice the return) by using various forms of derivative transactions.
Inverse ETFs seek to negatively correlate with the performance of a particular
index by using various forms of derivative transactions, including by
short-selling the underlying index. An investment in an inverse ETF will
decrease in value when the value of the underlying index rises. By investing in
leveraged ETFs or inverse ETFs, the fund can commit fewer assets to the
investment in the securities represented on the index than would otherwise be
required.

Leveraged ETFs and inverse ETFs present all of the risks that regular ETFs
present. In addition, leveraged ETFs and inverse ETFs determine their return
over a specific, pre-set time period, typically daily, and, as a result, there
is no guarantee that the ETF's actual long term returns will be equal to the
daily return that the fund seeks to achieve. For example, on a long-term basis
(e.g., a period of 6 months or a year), the return of a leveraged ETF may in
fact be considerably less than two times the long-term return of the tracked
index. Furthermore, because leveraged ETFs and inverse ETFs achieve their
results by using derivative instruments, they are subject to the risks
associated with derivative transactions, including the risk that the value of
the derivatives may rise or fall more rapidly than other investments, thereby
causing the ETF to lose money and, consequently, the value of the fund's
investment to decrease. Investing in derivative instruments also involves the
risk that other parties to the derivative contract may fail to meet their
obligations, which could cause losses to the ETF. Short sales in particular are
subject to the risk that, if the price of


                                       21


the security sold short increases, the inverse ETF may have to cover its short
position at a higher price than the short sale price, resulting in a loss to
the inverse ETF and, indirectly, to the fund. An ETF's use of these techniques
will make the fund's investment in the ETF more volatile than if the fund were
to invest directly in the securities underlying the tracked index, or in an ETF
that does not use leverage or derivative instruments. However, by investing in
a leveraged ETF or an inverse ETF rather than directly purchasing and/or
selling derivative instruments, the fund will limit its potential loss solely
to the amount actually invested in the ETF (that is, the fund will not lose
more than the principal amount invested in the ETF).


REAL ESTATE INVESTMENT TRUSTS ("REITS")
The fund may invest in REITs. REITs are companies that invest primarily in
income producing real estate or real estate-related loans or interests. REITs
are generally classified as equity REITs, mortgage REITs or a combination of
equity and mortgage REITs. Equity REITs invest the majority of their assets
directly in real property and derive income primarily from the collection of
rents. Equity REITs can also realize capital gains by selling properties that
have appreciated in value. Mortgage REITs invest the majority of their assets
in real estate mortgages and derive income from the collection of interest
payments. REITs are not taxed on income distributed to shareholders provided
they comply with the applicable requirements of the Code. The fund will
indirectly bear its proportionate share of any management and other expenses
paid by REITs in which it invests in addition to the expenses paid by the fund.
Such indirect expenses are not reflected in the fee table or expense example in
the fund's prospectus. Debt securities issued by REITs are, for the most part,
general and unsecured obligations and are subject to risks associated with
REITs.

Investing in REITs involves certain unique risks in addition to those risks
associated with investing in the real estate industry in general. An equity
REIT may be affected by changes in the value of the underlying properties owned
by the REIT. A mortgage REIT may be affected by changes in interest rates and
the ability of the issuers of its portfolio mortgages to repay their
obligations. REITs are dependent upon the skills of their managers and are not
diversified. REITs are generally dependent upon maintaining cash flows to repay
borrowings and to make distributions to shareholders and are subject to the
risk of default by lessees or borrowers. REITs whose underlying assets are
concentrated in properties used by a particular industry, such as health care,
are also subject to risks associated with such industry.

REITs (especially mortgage REITs) are also subject to interest rate risks. When
interest rates decline, the value of a REIT's investment in fixed rate
obligations can be expected to rise. Conversely, when interest rates rise, the
value of a REIT's investment in fixed rate obligations can be expected to
decline. If the REIT invests in adjustable rate mortgage loans, the interest
rates on which are reset periodically, yields on a REIT's investments in such
loans will gradually align themselves to reflect changes in market interest
rates. This causes the value of such investments to fluctuate less dramatically
in response to interest rate fluctuations than would investments in fixed rate
obligations.

REITs may have limited financial resources, may trade less frequently and in a
limited volume and may be subject to more abrupt or erratic price movements
than larger company securities. Historically REITs have been more volatile in
price than the larger capitalization stocks included in the S&P 500.


DERIVATIVE INSTRUMENTS


DERIVATIVES
The fund may, but is not required to, use futures and options on securities,
indices and currencies, forward foreign currency exchange contracts and other
derivatives. A derivative is a security or instrument whose value is determined
by reference to the value or the change in value of one or more securities,
currencies, indices or other financial instruments. The fund may use
derivatives for a variety of purposes, including: in an attempt to hedge
against adverse changes in the market prices of securities, interest rates or
currency exchange rates; as a substitute for purchasing or selling securities;
to attempt to increase the fund's return as a non-hedging strategy that may be
considered speculative; to manage portfolio characteristics (for example, for
funds investing in securities denominated in non-U.S. currencies, a portfolio's
currency exposure,


                                       22


or, for funds investing in fixed income securities, a portfolio's duration or
credit quality); and as a cash flow management technique. The fund may choose
not to make use of derivatives for a variety of reasons, and any use may be
limited by applicable law and regulations.

Using derivatives exposes the fund to additional risks and may increase the
volatility of the fund's net asset value and may not provide the expected
result. Derivatives may have a leveraging effect on the portfolio. Leverage
generally magnifies the effect of a change in the value of an asset and creates
a risk of loss of value in a larger pool of assets than the fund would
otherwise have had. Therefore, using derivatives can disproportionately
increase losses and reduce opportunities for gain. If changes in a derivative's
value do not correspond to changes in the value of the fund's other investments
or do not correlate well with the underlying assets, rate or index, the fund
may not fully benefit from, or could lose money on, or could experience
unusually high expenses as a result of, the derivative position. Derivatives
involve the risk of loss if the counterparty defaults on its obligation.
Certain derivatives may be less liquid, which may reduce the returns of the
fund if it cannot sell or terminate the derivative at an advantageous time or
price. The fund also may have to sell assets at inopportune times to satisfy
its obligations. The fund may not be able to purchase or sell a portfolio
security at a time that would otherwise be favorable for it to do so, or may
have to sell a portfolio security at a disadvantageous time or price to
maintain cover or to segregate securities in connection with its use of
derivatives. Some derivatives may involve the risk of improper valuation.
Suitable derivatives may not be available in all circumstances or at reasonable
prices and may not be used by the fund for a variety of reasons.

Financial reform laws enacted after the financial crisis of 2008-2009, such as
the Dodd-Frank Wall Street Reform and Consumer Protection Act ("Dodd-Frank"),
are changing many aspects of financial regulation applicable to derivatives.
For instance, Dodd-Frank calls for the comprehensive regulation of swaps by the
Commodity Futures Trading Commission (the "CFTC") and the Securities and
Exchange Commission (the "SEC"). The CFTC and the SEC are in the process of
adopting and implementing new regulations applicable to these instruments,
including rules with respect to recordkeeping, reporting, business conduct,
relationship documentation, margin, collateral, clearing, and trade execution
requirements. In addition, Dodd-Frank requires the registration of certain
parties that deal or engage in substantial trading, execution or advisory
activities in the markets for swaps. The extent and impact of these regulations
are not yet fully known and may not be known for some time.

The fund's use of derivatives may be affected by other applicable laws and
regulations and may be subject to review by the SEC, the CFTC, exchange and
market authorities and other regulators in the United States and abroad. The
fund's ability to use derivatives may be limited by tax considerations.

Certain derivatives transactions, including certain options, swaps, forward
contracts, and certain options on foreign currencies, are entered into directly
by the counterparties or through financial institutions acting as market makers
(OTC derivatives), rather than being traded on exchanges or in markets
registered with the CFTC or the SEC. Many of the protections afforded to
exchange participants will not be available to participants in OTC derivatives
transactions. For example, OTC derivatives transactions are not subject to the
guarantee of an exchange, and only OTC derivatives that are either required to
be cleared or submitted voluntarily for clearing to a clearinghouse will enjoy
all of the protections that central clearing provides against default by the
original counterparty to the trade. In an OTC derivatives transaction that is
not cleared, the fund bears the risk of default by its counterparty. In a
cleared derivatives transaction, the fund is instead exposed to the risk of
default of the clearinghouse and, to the extent the fund has posted any margin,
the risk of default of the broker through which it has entered into the
transaction. Information available on counterparty creditworthiness may be
incomplete or outdated, thus reducing the ability to anticipate counterparty
defaults.


                                       23


Derivatives involve operational risk. There may be incomplete or erroneous
documentation or inadequate collateral or margin, or transactions may fail to
settle. For derivatives not guaranteed by an exchange or clearinghouse, the
fund may have only contractual remedies in the event of a counterparty default,
and there may be delays, costs, or disagreements as to the meaning of
contractual terms and litigation in enforcing those remedies.

Swap contracts that are required to be cleared must be traded on a regulated
execution facility or contract market that makes them available for trading.
The establishment of a centralized exchange or market for swap transactions may
disrupt or limit the swap market and may not result in swaps being easier to
trade or value. Market-traded swaps may become more standardized, and the fund
may not be able to enter into swaps that meet its investment needs. The fund
also may not be able to find a clearinghouse willing to accept the swaps for
clearing. The new regulations may make using swaps more costly, may limit their
availability, or may otherwise adversely affect their value or performance.
Risks associated with the use of derivatives are magnified to the extent that a
large portion of the fund's assets are committed to derivatives in general or
are invested in just one or a few types of derivatives.


OPTIONS ON SECURITIES AND SECURITIES INDICES
The fund may purchase and write put and call options on any security in which
it may invest or options on any securities index based on securities in which
it may invest. The fund may also be able to enter into closing sale
transactions in order to realize gains or minimize losses on options it has
purchased.

WRITING CALL AND PUT OPTIONS ON SECURITIES. A call option written by the fund
obligates the fund to sell specified securities to the holder of the option at
a specified price if the option is exercised at any time before the expiration
date. The exercise price may differ from the market price of an underlying
security. The fund has the risk of loss that the price of an underlying
security may decline during the call period. The risk may be offset to some
extent by the premium the fund receives. If the value of the investment does
not rise above the call price, it's likely that the call will lapse without
being exercised. In that case, the fund would keep the cash premium and the
investment. All call options written by the fund are covered, which means that
the fund will own the securities subject to the options as long as the options
are outstanding, or the fund will use the other methods described below. The
fund's purpose in writing covered call options is to realize greater income
than would be realized on portfolio securities transactions alone. However, the
fund may forgo the opportunity to profit from an increase in the market price
of the underlying security.

A put option written by the fund would obligate the fund to purchase specified
securities from the option holder at a specified price if the option is
exercised at any time before the expiration date. The fund has no control over
when it may be required to purchase the underlying securities. All put options
written by the fund would be covered, which means that the fund would have
segregated assets with a value at least equal to the exercise price of the put
option. The purpose of writing such options is to generate additional income
for the fund. However, in return for the option premium, the fund accepts the
risk that it may be required to purchase the underlying security at a price in
excess of its market value at the time of purchase.

Call and put options written by the fund will also be considered to be covered
to the extent that the fund's liabilities under such options are wholly or
partially offset by its rights under call and put options purchased by the
fund. In addition, a written call option or put may be covered by entering into
an offsetting forward contract and/or by purchasing an offsetting option or any
other option which, by virtue of its exercise price or otherwise, reduces the
fund's net exposure on its written option position.

WRITING CALL AND PUT OPTIONS ON SECURITIES INDICES. The fund may also write
(sell) covered call and put options on any securities index composed of
securities in which it may invest. Options on securities indices are similar to
options on securities, except that the exercise of securities index options
requires cash payments and does not involve the actual purchase or sale of
securities. In addition, securities index options are designed to reflect price
fluctuations in a group of securities or segments of the securities market
rather than price fluctuations in a single security.


                                       24


The fund may cover call options on a securities index by owning securities
whose price changes are expected to be similar to those of the underlying
index, or by having an absolute and immediate right to acquire such securities
without additional cash consideration (or for additional consideration if cash
in such amount is segregated) upon conversion or exchange of other securities
in its portfolio. The fund may cover call and put options on a securities index
by segregating assets with a value equal to the exercise price.

Index options are subject to the timing risk inherent in writing index options.
When an index option is exercised, the amount of cash that the holder is
entitled to receive is determined by the difference between the exercise price
and the closing index level on the date when the option is exercised. If a fund
has purchased an index option and exercises it before the closing index value
for that day is available, it runs the risk that the level of the underlying
index may subsequently change. If such a change causes the exercised option to
fall "out-of-the-money", the fund will be required to pay cash in an amount of
the difference between the closing index value and the exercise price of the
option.

PURCHASING CALL AND PUT OPTIONS. The fund would normally purchase call options
in anticipation of an increase in the market value of securities of the type in
which it may invest. The purchase of a call option would entitle the fund, in
return for the premium paid, to purchase specified securities at a specified
price during the option period. The fund would ordinarily realize a gain if,
during the option period, the value of such securities exceeded the sum of the
exercise price, the premium paid and transaction costs; otherwise the fund
would realize either no gain or a loss on the purchase of the call option.

The fund would normally purchase put options in anticipation of a decline in
the market value of securities in its portfolio ("protective puts") or in
securities in which it may invest. The purchase of a put option would entitle
the fund, in exchange for the premium paid, to sell specified securities at a
specified price during the option period. The purchase of protective puts is
designed to offset or hedge against a decline in the market value of the fund's
securities. Put options may also be purchased by the fund for the purpose of
affirmatively benefiting from a decline in the price of securities which it
does not own. The fund would ordinarily realize a gain if, during the option
period, the value of the underlying securities decreased below the exercise
price sufficiently to more than cover the premium and transaction costs;
otherwise the fund would realize either no gain or a loss on the purchase of
the put option. Gains and losses on the purchase of protective put options
would tend to be offset by countervailing changes in the value of the
underlying portfolio securities.

The fund may terminate its obligations under an exchange-traded call or put
option by purchasing an option identical to the one it has written. Obligations
under over-the-counter options may be terminated only by entering into an
offsetting transaction with the counterparty to such option. Such purchases are
referred to as "closing purchase transactions."

OPTIONS SPREADS AND STRADDLES. Option spread and straddle transactions require
a fund to purchase and/or write more than one option simultaneously. A fund may
engage in option spread transactions in which it purchases and writes put or
call options on the same underlying instrument, with the options having
different exercise prices and/or expiration dates.

A fund also may engage in option straddles, in which it purchases or sells
combinations of put and call options on the same instrument. A long straddle is
a combination of a call and a put option purchased on the same security where
the exercise price of the put is less than or equal to the exercise price of
the call. A short straddle is a combination of a call and a put written on the
same security where the exercise price of the put is less than or equal to the
exercise price of the call and where the same issue of security or currency is
considered cover for both the put and the call.

RISKS OF TRADING OPTIONS. There is no assurance that a liquid secondary market
on an options exchange will exist for any particular exchange-traded option, or
at any particular time. If the fund is unable to effect a closing purchase
transaction with respect to covered options it has written, the fund will not
be able to sell the underlying securities or dispose of its segregated assets
until the options expire or are exercised.


                                       25


Similarly, if the fund is unable to effect a closing sale transaction with
respect to options it has purchased, it will have to exercise the options in
order to realize any profit and will incur transaction costs upon the purchase
or sale of underlying securities.

Reasons for the absence of a liquid secondary market on an exchange include the
following: (i) there may be insufficient trading interest in certain options;
(ii) restrictions may be imposed by an exchange on opening or closing
transactions or both; (iii) trading halts, suspensions or other restrictions
may be imposed with respect to particular classes or series of options; (iv)
unusual or unforeseen circumstances may interrupt normal operations on an
exchange; (v) the facilities of an exchange or the Options Clearing Corporation
(the "OCC") may not at all times be adequate to handle current trading volume;
or (vi) one or more exchanges could, for economic or other reasons, decide or
be compelled at some future date to discontinue the trading of options (or a
particular class or series of options), in which event the secondary market on
that exchange (or in that class or series of options) would cease to exist,
although it is expected that outstanding options on that exchange, if any, that
had been issued by the OCC as a result of trades on that exchange would
continue to be exercisable in accordance with their terms.

The fund may purchase and sell both options that are traded on U.S. and
non-U.S. exchanges and options traded over-the-counter with broker-dealers who
make markets in these options. The ability to terminate over-the-counter
options is more limited than with exchange-traded options and may involve the
risk that broker-dealers participating in such transactions will not fulfill
their obligations. Until such time as the staff of the SEC changes its
position, the fund will treat purchased over-the-counter options and all assets
used to cover written over-the-counter options as illiquid securities, except
that with respect to options written with primary dealers in U.S. government
securities pursuant to an agreement requiring a closing purchase transaction at
a formula price, the amount of illiquid securities may be calculated with
reference to the formula.

Transactions by the fund in options on securities and indices will be subject
to limitations established by each of the exchanges, boards of trade or other
trading facilities governing the maximum number of options in each class which
may be written or purchased by a single investor or group of investors acting
in concert. Thus, the number of options which the fund may write or purchase
may be affected by options written or purchased by other investment advisory
clients of Pioneer. An exchange, board of trade or other trading facility may
order the liquidations of positions found to be in excess of these limits, and
it may impose certain other sanctions.

The writing and purchase of options is a highly specialized activity which
involves investment techniques and risks different from those associated with
ordinary portfolio securities transactions. The successful use of protective
puts for hedging purposes depends in part on the ability of Pioneer to predict
future price fluctuations and the degree of correlation between the options and
securities markets.

The hours of trading for options may not conform to the hours during which the
underlying securities are traded. To the extent that the options markets close
before the markets for the underlying securities, significant price movements
can take place in the underlying markets that cannot be reflected in the
options markets.

In addition to the risks of imperfect correlation between the portfolio and the
index underlying the option, the purchase of securities index options involves
the risk that the premium and transaction costs paid by the fund in purchasing
an option will be lost. This could occur as a result of unanticipated movements
in the price of the securities comprising the securities index on which the
option is based.


FUTURES CONTRACTS AND OPTIONS ON FUTURES CONTRACTS
The fund may purchase and sell various kinds of futures contracts, and purchase
and write (sell) call and put options on any of such futures contracts. The
fund may enter into closing purchase and sale transactions with respect to any
futures contracts and options on futures contracts. The futures contracts may
be based on various securities (such as U.S. government securities), securities
indices, foreign currencies and other financial instruments and indices. The
fund may invest in futures contracts based on the Chicago Board of


                                       26


Exchange Volatility Index ("VIX Futures"). The VIX is an index of market
sentiment derived from the S&P 500 option prices, and is designed to reflect
investors' consensus view of expected stock market volatility over future
periods. The fund may invest in futures and options based on credit derivative
contracts on baskets or indices of securities, such as CDX. An interest rate
futures contract provides for the future sale by one party and the purchase by
the other party of a specified amount of a particular financial instrument
(debt security) at a specified price, date, time and place. The fund will
engage in futures and related options transactions for bona fide hedging and
non-hedging purposes as described below. All futures contracts entered into by
the fund are traded on U.S. exchanges or boards of trade that are licensed and
regulated by the CFTC or on non-U.S. exchanges.

FUTURES CONTRACTS. A futures contract may generally be described as an
agreement between two parties to buy and sell particular financial instruments
for an agreed price during a designated month (or to deliver the final cash
settlement price, in the case of a contract relating to an index or otherwise
not calling for physical delivery at the end of trading in the contract).

When interest rates are rising or securities prices are falling, the fund can
seek to offset a decline in the value of its current portfolio securities
through the sale of futures contracts. When interest rates are falling or
securities prices are rising, the fund, through the purchase of futures
contracts, can attempt to secure better rates or prices than might later be
available in the market when it effects anticipated purchases. Similarly, the
fund can sell futures contracts on a specified currency to protect against a
decline in the value of such currency and a decline in the value of its
portfolio securities which are denominated in such currency. The fund can
purchase futures contracts on a foreign currency to establish the price in U.S.
dollars of a security denominated in such currency that the fund has acquired
or expects to acquire.

Positions taken in the futures markets are not normally held to maturity but
are instead liquidated through offsetting transactions which may result in a
profit or a loss. While futures contracts on securities or currency will
usually be liquidated in this manner, the fund may instead make, or take,
delivery of the underlying securities or currency whenever it appears
economically advantageous to do so. A clearing corporation associated with the
exchange on which futures on securities or currency are traded guarantees that,
if still open, the sale or purchase will be performed on the settlement date.

HEDGING STRATEGIES. Hedging, by use of futures contracts, seeks to establish
with more certainty the effective price, rate of return and currency exchange
rate on portfolio securities and securities that the fund owns or proposes to
acquire. The fund may, for example, take a "short" position in the futures
market by selling futures contracts in order to hedge against an anticipated
rise in interest rates or a decline in market prices or foreign currency rates
that would adversely affect the value of the fund's securities. Such futures
contracts may include contracts for the future delivery of securities held by
the fund or securities with characteristics similar to those of the fund's
securities. Similarly, the fund may sell futures contracts in a foreign
currency in which its portfolio securities are denominated or in one currency
to hedge against fluctuations in the value of securities denominated in a
different currency if there is an established historical pattern of correlation
between the two currencies. If, in the opinion of Pioneer, there is a
sufficient degree of correlation between price trends for the fund's securities
and futures contracts based on other financial instruments, securities indices
or other indices, the fund may also enter into such futures contracts as part
of its hedging strategies. Although under some circumstances prices of
securities in the portfolio may be more or less volatile than prices of such
futures contracts, Pioneer will attempt to estimate the extent of this
volatility difference based on historical patterns and compensate for any such
differential by having the fund enter into a greater or lesser number of
futures contracts or by attempting to achieve only a partial hedge against
price changes affecting the fund's securities. When hedging of this character
is successful, any depreciation in the value of portfolio securities will be
substantially offset by appreciation in the value of the futures position. On
the other hand, any unanticipated appreciation in the value of the portfolio
securities would be substantially offset by a decline in the value of the
futures position.


                                       27


On other occasions, the fund may take a "long" position by purchasing futures
contracts. This may be done, for example, when the fund anticipates the
subsequent purchase of particular securities when it has the necessary cash,
but expects the prices or currency exchange rates then available in the
applicable market to be less favorable than prices or rates that are currently
available.

OPTIONS ON FUTURES CONTRACTS. The acquisition of put and call options on
futures contracts will give the fund the right (but not the obligation) for a
specified price to sell or to purchase, respectively, the underlying futures
contract at any time during the option period. As the purchaser of an option on
a futures contract, the fund obtains the benefit of the futures position if
prices move in a favorable direction, but limits its risk of loss in the event
of an unfavorable price movement to the loss of the premium and transaction
costs.

The writing of a call option on a futures contract generates a premium which
may partially offset a decline in the value of the fund's assets. By writing a
call option, the fund becomes obligated, in exchange for the premium, to sell a
futures contract (if the option is exercised), which may have a value higher
than the exercise price. Conversely, the writing of a put option on a futures
contract generates a premium which may partially offset an increase in the
price of securities that the fund intends to purchase. However, the fund
becomes obligated to purchase a futures contract (if the option is exercised)
which may have a value lower than the exercise price. Thus, the loss incurred
by the fund in writing options on futures is potentially unlimited and may
exceed the amount of the premium received. The fund will incur transaction
costs in connection with the writing of options on futures.

The holder or writer of an option on a futures contract may terminate its
position by selling or purchasing an offsetting option on the same series.
There is no guarantee that such closing transactions can be effected. The
fund's ability to establish and close out positions on such options will be
subject to the development and maintenance of a liquid market.

OTHER CONSIDERATIONS REGARDING FUTURES CONTRACTS. The fund will engage in
transactions in futures contracts and related options only to the extent such
transactions are consistent with the requirements of the Code for maintaining
its qualification as a regulated investment company for U.S. federal income tax
purposes.

Futures contracts and related options involve brokerage costs, require margin
deposits and, in the case of contracts and options obligating the fund to
purchase securities or currencies, require the fund to segregate assets to
cover such contracts and options.

While transactions in futures contracts and options on futures may reduce
certain risks, such transactions themselves entail certain other risks. Thus,
while the fund may benefit from the use of futures and options on futures,
unanticipated changes in interest rates, securities prices or currency exchange
rates may result in a poorer overall performance for the fund than if it had
not entered into any futures contracts or options transactions. When futures
contracts and options are used for hedging purposes, perfect correlation
between the fund's futures positions and portfolio positions may be impossible
to achieve, particularly where futures contracts based on individual securities
are currently not available. In the event of an imperfect correlation between a
futures position and a portfolio position which is intended to be protected,
the desired protection may not be obtained and the fund may be exposed to risk
of loss. It is not possible to hedge fully or perfectly against the effect of
currency fluctuations on the value of non-U.S. securities because currency
movements impact the value of different securities in differing degrees.

If the fund were unable to liquidate a futures contract or an option on a
futures position due to the absence of a liquid secondary market, the
imposition of price limits or otherwise, it could incur substantial losses. The
fund would continue to be subject to market risk with respect to the position.
In addition, except in the case of purchased options, the fund would continue
to be required to make daily variation margin payments and might be required to
maintain the position being hedged by the future or option or to maintain cash
or securities in a segregated account.


                                       28


INTEREST RATE SWAPS, COLLARS, CAPS AND FLOORS
In order to hedge the value of the portfolio against interest rate fluctuations
or to enhance the fund's income, the fund may, but is not required to, enter
into various interest rate transactions such as interest rate swaps and the
purchase or sale of interest rate caps and floors. To the extent that the fund
enters into these transactions, the fund expects to do so primarily to preserve
a return or spread on a particular investment or portion of its portfolio or to
protect against any increase in the price of securities the fund anticipates
purchasing at a later date. The fund intends to use these transactions
primarily as a hedge and not as a speculative investment. However, the fund
also may invest in interest rate swaps to enhance income or to increase the
fund's yield, for example, during periods of steep interest rate yield curves
(i.e., wide differences between short-term and long-term interest rates). The
fund is not required to hedge its portfolio and may choose not to do so. The
fund cannot guarantee that any hedging strategies it uses will work.

In an interest rate swap, the fund exchanges with another party their
respective commitments to pay or receive interest (e.g., an exchange of fixed
rate payments for floating rate payments). For example, if the fund holds a
debt instrument with an interest rate that is reset only once each year, it may
swap the right to receive interest at this fixed rate for the right to receive
interest at a rate that is reset every week. This would enable the fund to
offset a decline in the value of the debt instrument due to rising interest
rates but would also limit its ability to benefit from falling interest rates.
Conversely, if the fund holds a debt instrument with an interest rate that is
reset every week and it would like to lock in what it believes to be a high
interest rate for one year, it may swap the right to receive interest at this
variable weekly rate for the right to receive interest at a rate that is fixed
for one year. Such a swap would protect the fund from a reduction in yield due
to falling interest rates and may permit the fund to enhance its income through
the positive differential between one week and one year interest rates, but
would preclude it from taking full advantage of rising interest rates.

The fund usually will enter into interest rate swaps on a net basis (i.e., the
two payment streams are netted out with the fund receiving or paying, as the
case may be, only the net amount of the two payments). The net amount of the
excess, if any, of the fund's obligations over its entitlements with respect to
each interest rate swap will be accrued on a daily basis, and an amount of cash
or liquid instruments having an aggregate net asset value at least equal to the
accrued excess will be maintained in a segregated account by the fund's
custodian. If the interest rate swap transaction is entered into on other than
a net basis, the full amount of the fund's obligations will be accrued on a
daily basis, and the full amount of the fund's obligations will be maintained
in a segregated account by the fund's custodian.

The fund also may engage in interest rate transactions in the form of
purchasing or selling interest rate caps or floors. The fund will not sell
interest rate caps or floors that it does not own. The purchase of an interest
rate cap entitles the purchaser, to the extent that a specified index exceeds a
predetermined interest rate, to receive payments of interest equal to the
difference of the index and the predetermined rate on a notional principal
amount (i.e., the reference amount with respect to which interest obligations
are determined although no actual exchange of principal occurs) from the party
selling such interest rate cap. The purchase of an interest rate floor entitles
the purchaser, to the extent that a specified index falls below a predetermined
interest rate, to receive payments of interest at the difference of the index
and the predetermined rate on a notional principal amount from the party
selling such interest rate floor. The fund will not enter into caps or floors
if, on a net basis, the aggregate notional principal amount with respect to
such agreements exceeds the net assets of the fund.

Typically, the parties with which the fund will enter into interest rate
transactions will be broker-dealers and other financial institutions. The fund
will not enter into any interest rate swap, cap or floor transaction unless the
unsecured senior debt or the claims-paying ability of the other party thereto
is rated investment grade quality by at least one nationally recognized
statistical rating organization at the time of entering into such transaction
or whose creditworthiness is believed by the fund's adviser to be equivalent to
such rating. If there is a default by the other party to such a transaction,
the fund will have contractual remedies


                                       29


pursuant to the agreements related to the transaction. The swap market has
grown substantially in recent years with a large number of banks and investment
banking firms acting both as principals and as agents utilizing standardized
swap documentation. Caps and floors are less liquid than swaps. Certain federal
income tax requirements may limit the fund's ability to engage in interest rate
swaps.


TOTAL RETURN SWAPS, CAPS, FLOORS AND COLLARS
The fund may enter into total return swaps, caps, floors and collars to hedge
assets or liabilities or to seek to increase total return. Total return swaps
involve the exchange by a fund with another party of their respective
commitments to make or receive payments based on the change in market value of
a specified security, basket of securities or benchmark. The fund may invest in
swaps based on VIX futures contracts. The VIX is an index of market sentiment
derived from S&P 500 Index option prices, and is designed to reflect investors'
consensus view of expected stock market volatility over future periods. Total
return swaps may be used to obtain exposure to a security or market without
owning or taking physical custody of such security or market. The purchase of a
cap entitles the purchaser, to the extent that the market value of a specified
security or benchmark exceeds a predetermined level, to receive payments of a
contractually-based amount from the party selling the cap. The purchase of a
floor entitles the purchaser, to the extent that the market value of a
specified security or benchmark falls below a predetermined level, to receive
payments of a contractually-based amount from the party selling the floor. A
collar is a combination of a cap and a floor that preserves a certain return
within a predetermined range of values. Investments in swaps, caps, floors and
collars are highly specialized activities which involve investment techniques
and risks different from those associated with ordinary portfolio transactions.
Investments in total return swaps, caps, floors and collars may be considered
speculative because they involve significant risk of loss. If Pioneer is
incorrect in its forecast of market values, these investments could negatively
impact the fund's performance. These investments also are subject to default
risk of the counterparty and may be less liquid than other portfolio
securities. Moreover, investments in swaps, caps, floors and collars may
involve greater transaction costs than investments in other securities.


CREDIT DEFAULT SWAP AGREEMENTS
The fund may enter into credit default swap agreements. The "buyer" in a credit
default contract is obligated to pay the "seller" a periodic stream of payments
over the term of the contract provided that no specified events of default, or
"credit events", on an underlying reference obligation have occurred. If such a
credit event occurs, the seller must pay the buyer the "par value" (full
notional value) of the reference obligation in exchange for the reference
obligation, or must make a cash settlement payment. The fund may be either the
buyer or seller in the transaction. If the fund is a buyer and no credit event
occurs, the fund will receive no return on the stream of payments made to the
seller. However, if a credit event occurs, the fund, as the buyer, receives the
full notional value for a reference obligation that may have little or no
value. As a seller, the fund receives a fixed rate of income throughout the
term of the contract, which typically is between six months and three years,
provided that there is no credit event. If a credit event occurs, the fund, as
the seller, must pay the buyer the full notional value of the reference
obligation. The fund, as the seller, would be entitled to receive the reference
obligation. Alternatively, the fund may be required to make a cash settlement
payment, where the reference obligation is received by the fund as seller. The
value of the reference obligation, coupled with the periodic payments
previously received, would likely be less than the full notional value the fund
pays to the buyer, resulting in a loss of value to the fund as seller. When the
fund acts as a seller of a credit default swap agreement it is exposed to the
risks of a leveraged transaction. Credit default swaps may involve greater
risks than if the fund had invested in the reference obligation directly. In
addition to general market risks, credit default swaps are subject to
illiquidity risk, counterparty risk and credit risk. The fund will enter into
swap agreements only with counterparties who are rated investment grade quality
by at least one nationally recognized statistical rating organization at the
time of entering into such transaction or whose creditworthiness is believed to
be equivalent to such rating.


                                       30


Recent legislation will require most swaps to be executed through a centralized
exchange or regulated facility and be cleared through a regulated
clearinghouse. The swap market could be disrupted or limited as a result of
this legislation, which could adversely affect the fund. Moreover, the
establishment of a centralized exchange or market for swap transactions may not
result in swaps being easier to trade or value.

The fund may also invest in credit derivative contracts on baskets or indices
of securities, such as CDX. A CDX can be used to hedge credit risk or to take a
position on a basket of credit entities or indices. The individual credits
underlying credit default swap indices may be rated investment grade or
non-investment grade. These instruments are designed to track representative
segments of the credit default swap market such as investment grade, below
investment grade and emerging markets. A CDX index tranche provides access to
customized risk, exposing each investor to losses at different levels of
subordination. The lowest part of the capital structure is called the "equity
tranche" as it has exposure to the first losses experienced in the basket. The
mezzanine and senior tranches are higher in the capital structure but can also
be exposed to loss in value. Investments are subject to liquidity risks as well
as other risks associated with investments in credit default swaps.


CREDIT-LINKED NOTES
The fund may invest in credit-linked notes ("CLNs"), which are derivative
instruments. A CLN is a synthetic obligation between two or more parties where
the payment of principal and/or interest is based on the performance of some
obligation (a reference obligation). In addition to credit risk of the
reference obligations and interest rate risk, the buyer/seller of the CLN is
subject to counterparty risk.


EXCHANGE TRADED NOTES
The fund may invest in exchange traded notes ("ETNs"). An ETN is a type of
senior, unsecured, unsubordinated debt security issued by financial
institutions that combines both aspects of bonds and ETFs. An ETN's returns are
based on the performance of a market index or other reference asset minus fees
and expenses. Similar to ETFs, ETNs are listed on an exchange and traded in the
secondary market. However, unlike an ETF, an ETN can be held until the ETN's
maturity, at which time the issuer will pay a return linked to the performance
of the market index or other reference asset to which the ETN is linked minus
certain fees. Unlike regular bonds, ETNs do not make periodic interest payments
and principal is not protected.

An ETN that is tied to a specific index may not be able to replicate and
maintain exactly the composition and relative weighting of securities,
commodities or other components in the applicable index. ETNs also incur
certain expenses not incurred by their applicable index. Additionally, certain
components comprising the index tracked by an ETN may, at times, be temporarily
unavailable, which may impede an ETN's ability to track its index. Some ETNs
that use leverage can, at times, be relatively illiquid and, thus, they may be
difficult to purchase or sell at a fair price. Leveraged ETNs are subject to
the same risk as other instruments that use leverage in any form. While
leverage allows for greater potential return, the potential for loss is also
greater. However, the fund's potential loss is limited to the amount actually
invested in the ETN.

The market value of an ETN is influenced by supply and demand for the ETN, the
current performance of the index or other reference asset, the credit rating of
the ETN issuer, volatility and lack of liquidity in the reference asset,
changes in the applicable interest rates, and economic, legal, political or
geographic events that affect the reference asset. The market value of ETN
shares may differ from their net asset value. This difference in price may be
due to the fact that the supply and demand in the market for ETN shares at any
point in time is not always identical to the supply and demand in the market
for the securities underlying the index (or other reference asset) that the ETN
seeks to track. The value of an ETN may also change due to a change in the
issuer's credit rating. As a result, there may be times when an ETN share
trades at a premium or discount to its net asset value. The fund will bear its
pro rata portion of any fees and expenses borne by the ETN. These fees and
expenses generally reduce the return realized at maturity or upon redemption
from an investment in an ETN.


                                       31


COMMODITY-LINKED INVESTMENTS
The fund may seek to provide exposure to the investment returns of real assets
that trade in the commodity markets through investments in commodity-linked
investments, including commodities futures contracts, commodity-linked
derivatives, and commodity-linked notes. Real assets are assets such as oil,
gas, industrial and precious metals, livestock, and agricultural or meat
products, or other items that have tangible properties, as compared to stocks
or bonds, which are financial instruments. The value of commodity-linked
investments held by the fund may be affected by a variety of factors,
including, but not limited to, overall market movements and other factors
affecting the value of particular industries or commodities, such as weather,
disease, embargoes, acts of war or terrorism, or political and regulatory
developments.

The prices of commodity-linked investments may move in different directions
than investments in traditional equity and debt securities when the value of
those traditional securities is declining due to adverse economic conditions.
As an example, during periods of rising inflation, debt securities have
historically tended to decline in value due to the general increase in
prevailing interest rates. Conversely, during those same periods of rising
inflation, the prices of certain commodities, such as oil and metals, have
historically tended to increase. Of course, there cannot be any guarantee that
these investments will perform in that manner in the future, and at certain
times the price movements of commodity-linked investments have been parallel to
those of debt and equity securities. Commodities have historically tended to
increase and decrease in value during different parts of the business cycle
than financial assets. Nevertheless, at various times, commodities prices may
move in tandem with the prices of financial assets and thus may not provide
overall portfolio diversification benefits. Under favorable economic
conditions, the fund's commodity-linked investments may be expected to
underperform an investment in traditional securities.

Because commodity-linked derivatives are available from a relatively small
number of issuers, the fund's investments in commodity-linked derivatives are
particularly subject to counterparty risk, which is the risk that the issuer of
the commodity-linked derivative (which issuer may serve as counterparty to a
substantial number of the fund's commodity-linked and other derivative
investments) will not fulfill its contractual obligations.

The fund may gain exposure to commodities by investing in ETFs. ETFs that
invest in commodities may be, or may become subject to CFTC trading regulations
that limit the amount of commodity contracts an ETF may hold. Such regulations
would hurt the value of such ETF's securities. Additionally, some commodity
ETFs invest in commodity futures, which can lose money even when commodity
prices are rising.


FOREIGN CURRENCY SWAPS
Foreign currency swaps involve the exchange by the lenders, including the Fund,
with another party (the "counterparty") of the right to receive the currency in
which the loans are denominated for the right to receive U.S. dollars. The Fund
will enter into a foreign currency swap only if the outstanding debt
obligations of the counterparty are rated investment grade quality by at least
one nationally recognized statistical rating organization at the time of
entering into such transaction or whose creditworthiness is believed by the
fund's adviser to be equivalent to such rating. The amounts of U.S. dollar
payments to be received by the fund and the foreign currency payments to be
received by the counterparty are fixed at the time the swap arrangement is
entered into. Accordingly, the swap protects the fund from the fluctuations in
exchange rates and locks in the right to receive payments under the loan in a
predetermined amount of U.S. dollars. If there is a default by the
counterparty, the fund will have contractual remedies pursuant to the swap
agreement; however, the U.S. dollar value of the fund's right to receive
foreign currency payments under the obligation will be subject to fluctuations
in the applicable exchange rate to the extent that a replacement swap
arrangement is unavailable or the fund is unable to recover damages from the
defaulting counterparty.


CROSS CURRENCY INTEREST RATE SWAP AGREEMENTS
Cross currency interest rate swap agreements combine features of currency swap
agreements and interest rate swap agreements. The cross currency interest rate
swaps in which the fund may enter generally will involve both the exchange of
currency and the payment of interest streams with reference to one currency
based on a specified index in exchange for receiving interest streams with
reference to the other currency.


                                       32


Such swaps may involve initial and final exchanges that correspond to the
agreed upon transaction amount. For example, the payment stream on a specified
amount of euro based on a European market floating rate might be exchanged for
a U.S. oriented floating rate on the same principal amount converted into U.S.
dollars.

FINANCIAL FUTURES AND OPTIONS TRANSACTIONS

Pioneer has claimed an exclusion from registration as a "commodity pool
operator" with respect to the fund under the Commodity Exchange Act (the
"CEA"), and, therefore, Pioneer will not, with respect to its management of the
fund, be subject to registration or regulation as a commodity pool operator.

Under this exemption, the fund will remain limited in its ability to trade
instruments subject to the jurisdiction of the CFTC, including commodity
futures (which include futures on broad-based securities indexes and interest
rate futures), options on commodity futures and swaps. This limitation also
applies with respect to any indirect exposure that the fund may have to these
instruments through investments in other funds. Pioneer may have to rely on
representations from the underlying fund's manager about the amount (or maximum
permitted amount) of investment exposure that the underlying fund has to
instruments such as commodity futures, options on commodity futures and swaps.

Under this exemption, the fund must satisfy one of the following two trading
limitations at all times: (1) the aggregate initial margin and premiums
required to establish the fund's positions in commodity futures, options on
commodity futures, swaps and other CFTC-regulated instruments may not exceed 5%
of the liquidation value of the fund's portfolio (after accounting for
unrealized profits and unrealized losses on any such investments); or (2) the
aggregate net notional value of such instruments, determined at the time the
most recent position was established, may not exceed 100% of the liquidation
value of the fund's portfolio (after accounting for unrealized profits and
unrealized losses on any such positions). The fund would not be required to
consider its exposure to such instruments if they were held for "bona fide
hedging" purposes, as such term is defined in the rules of the CFTC. In
addition to meeting one of the foregoing trading limitations, the fund may not
market itself as a commodity pool or otherwise as a vehicle for trading in the
markets for CFTC-regulated instruments.


OTHER INVESTMENTS AND INVESTMENT TECHNIQUES


SHORT-TERM INVESTMENTS
For temporary defensive or cash management purposes, the fund may invest in all
types of short-term investments including, but not limited to, (a) commercial
paper and other short-term commercial obligations; (b) obligations (including
certificates of deposit and bankers' acceptances) of banks; (c) obligations
issued or guaranteed by a governmental issuer, including governmental agencies
or instrumentalities; (d) fixed income securities of non-governmental issuers;
and (e) other cash equivalents or cash. Subject to the fund's restrictions
regarding investment in non-U.S. securities, these securities may be
denominated in any currency. Although these investments generally are rated
investment grade or are determined by Pioneer to be of equivalent credit
quality, the fund may also invest in these instruments if they are rated below
investment grade in accordance with its investment objectives, policies and
restrictions.


ILLIQUID SECURITIES
The fund may invest up to 15% of its net assets in illiquid and other
securities that are not readily marketable. If due to subsequent fluctuations
in value or any other reasons, the value of the fund's illiquid securities
exceeds this percentage limitation, the fund will consider what actions, if
any, are necessary to maintain adequate liquidity. Repurchase agreements
maturing in more than seven days will be included for purposes of the foregoing
limit. Securities subject to restrictions on resale under the Securities Act of
1933, as amended (the "1933 Act"), are considered illiquid unless they are
eligible for resale pursuant to Rule 144A or another exemption from the
registration requirements of the 1933 Act and are determined to be liquid by
Pioneer. Pioneer determines the liquidity of Rule 144A and other restricted
securities according to procedures adopted by the Board of Trustees. Under the
direction of the Board of Trustees, Pioneer monitors


                                       33


the application of these guidelines and procedures. The inability of the fund
to dispose of illiquid investments readily or at reasonable prices could impair
the fund's ability to raise cash for redemptions or other purposes. If the fund
sold restricted securities other than pursuant to an exception from
registration under the 1933 Act such as Rule 144A, it may be deemed to be
acting as an underwriter and subject to liability under the 1933 Act.


REPURCHASE AGREEMENTS
The fund may enter into repurchase agreements with broker-dealers, member banks
of the Federal Reserve System and other financial institutions. Repurchase
agreements are arrangements under which the fund purchases securities and the
seller agrees to repurchase the securities within a specific time and at a
specific price. The repurchase price is generally higher than the fund's
purchase price, with the difference being income to the fund. A repurchase
agreement may be considered a loan by the fund collateralized by securities.
Under the direction of the Board of Trustees, Pioneer reviews and monitors the
creditworthiness of any institution which enters into a repurchase agreement
with the fund. The counterparty's obligations under the repurchase agreement
are collateralized with U.S. Treasury and/or agency obligations with a market
value of not less than 100% of the obligations, valued daily. Collateral is
held by the fund's custodian in a segregated, safekeeping account for the
benefit of the fund. Repurchase agreements afford the fund an opportunity to
earn income on temporarily available cash. In the event of commencement of
bankruptcy or insolvency proceedings with respect to the seller of the security
before repurchase of the security under a repurchase agreement, the fund may
encounter delay and incur costs before being able to sell the security. Such a
delay may involve loss of interest or a decline in price of the security. If
the court characterizes the transaction as a loan and the fund has not
perfected a security interest in the security, the fund may be required to
return the security to the seller's estate and be treated as an unsecured
creditor of the seller. As an unsecured creditor, the fund would be at risk of
losing some or all of the principal and interest involved in the transaction.
There is no specific limit on the fund's ability to enter into repurchase
agreements. The SEC frequently treats repurchase agreements as loans for
purposes of the 1940 Act.


REVERSE REPURCHASE AGREEMENTS
Reverse repurchase agreements involve the sale of securities to a bank or other
institution with an agreement that the fund will buy back the securities at a
fixed future date at a fixed price plus an agreed amount of "interest" which
may be reflected in the repurchase price. Reverse repurchase agreements involve
the risk that the market value of securities purchased by the fund with
proceeds of the transaction may decline below the repurchase price of the
securities sold by the fund that it is obligated to repurchase. The fund will
also continue to be subject to the risk of a decline in the market value of the
securities sold under the agreements because it will reacquire those securities
upon effecting their repurchase. Reverse repurchase agreements may be
considered to be a type of borrowing. The 1940 Act permits a fund to borrow
money in amounts of up to one-third of the fund's total assets from banks for
any purpose and up to 5% of the fund's total assets from banks and other
lenders for temporary purposes. The fund will segregate assets in an amount at
least equal to the repurchase price of the securities.


SHORT SALES AGAINST THE BOX
The fund may sell securities "short against the box." A short sale involves the
fund borrowing securities from a broker and selling the borrowed securities.
The fund has an obligation to return securities identical to the borrowed
securities to the broker. In a short sale against the box, the fund at all
times owns an equal amount of the security sold short or securities convertible
into or exchangeable for, with or without payment of additional consideration,
an equal amount of the security sold short. The fund intends to use short sales
against the box to hedge. For example when the fund believes that the price of
a current portfolio security may decline, the fund may use a short sale against
the box to lock in a sale price for a security rather than selling the security
immediately. In such a case, any future losses in the fund's long position
should be offset by a gain in the short position and, conversely, any gain in
the long position should be reduced by a loss in the short position. The fund
may engage in short sales of securities only against the box.


                                       34


If the fund effects a short sale against the box at a time when it has an
unrealized gain on the security, it may be required to recognize that gain as
if it had actually sold the security (a "constructive sale") on the date it
effects the short sale. However, such constructive sale treatment may not apply
if the fund closes out the short sale with securities other than the
appreciated securities held at the time of the short sale provided that certain
other conditions are satisfied. Uncertainty regarding the tax consequences of
effecting short sales may limit the extent to which the fund may make short
sales against the box.


DOLLAR ROLLS
The fund may enter into mortgage "dollar rolls" in which the fund sells
securities for delivery in the current month and simultaneously contracts with
the same counterparty to repurchase similar (same type, coupon and maturity),
but not identical securities on a specified future date. During the roll
period, the fund loses the right to receive principal and interest paid on the
securities sold. However, the fund would benefit to the extent of any
difference between the price received for the securities sold and the lower
forward price for the future purchase (often referred to as the "drop") or fee
income plus the interest earned on the cash proceeds of the securities sold
until the settlement date of the forward purchase. Unless such benefits exceed
the income, capital appreciation and gain or loss due to mortgage prepayments
that would have been realized on the securities sold as part of the mortgage
dollar roll, the use of this technique will diminish the investment performance
of the fund compared with what such performance would have been without the use
of mortgage dollar rolls. All cash proceeds will be invested in instruments
that are permissible investments for the fund. The fund will hold and maintain
in a segregated account until the settlement date cash or liquid securities in
an amount equal to its forward purchase price.

For financial reporting and tax purposes, the fund treats mortgage dollar rolls
as two separate transactions; one involving the purchase of a security and a
separate transaction involving a sale.

Dollar rolls involve certain risks including the following: if the
broker-dealer to whom the fund sells the security becomes insolvent, the fund's
right to purchase or repurchase the securities subject to the dollar roll may
be restricted and the instrument which the fund is required to repurchase may
be worth less than an instrument which the fund originally held. Successful use
of dollar rolls will depend upon Pioneer's ability to manage its interest rate
and prepayment exposure. There is no assurance that dollar rolls can be
successfully employed.


ASSET SEGREGATION
The 1940 Act requires that the fund segregate assets in connection with certain
types of transactions that may have the effect of leveraging the portfolio. If
the fund enters into a transaction requiring segregation, such as a forward
commitment or a reverse repurchase agreement, the custodian or Pioneer will
segregate liquid assets in an amount required to comply with the 1940 Act. If a
fund sells or writes credit default swaps, it will segregate liquid assets at
least equal to the full notional value of such credit default swaps. Such
segregated assets will be valued at market daily. If the aggregate value of
such segregated assets declines below the aggregate value required to satisfy
the 1940 Act, additional liquid assets will be segregated. In some instances a
fund may "cover" its obligation using other methods to the extent permitted
under the 1940 Act, orders or releases issued by the SEC thereunder, or
no-action letters or other guidance of the SEC staff.


PORTFOLIO TURNOVER
It is the policy of the fund not to engage in trading for short-term profits,
although portfolio turnover rate is not considered a limiting factor in the
execution of investment decisions for the fund. A high rate of portfolio
turnover (100% or more) involves correspondingly greater transaction costs
which must be borne by the fund and its shareholders. See "Annual Fee, Expense
and Other Information" for the fund's annual portfolio turnover rate.


                                       35


LENDING OF PORTFOLIO SECURITIES
The fund may lend portfolio securities to registered broker-dealers or other
institutional investors deemed by Pioneer to be of good standing under
agreements which require that the loans be secured continuously by collateral
in the form of cash, cash equivalents, U.S. Government securities or
irrevocable letters of credit issued by banks approved by the fund. The value
of the collateral is monitored on a daily basis and the borrower is required to
maintain the collateral at an amount at least equal to the market value of the
securities loaned. The fund continues to receive the equivalent of the interest
or dividends paid by the issuer on the securities loaned and continues to have
all of the other risks associated with owning the securities. Where the
collateral received is cash, the cash will be invested and the fund will be
entitled to a share of the income earned on the investment, but will also be
subject to investment risk on the collateral and will bear the entire amount of
any loss in connection with investment of such collateral. The fund may pay
administrative and custodial fees in connection with loans of securities and,
where the collateral received is cash, the fund may pay a portion of the income
earned on the investment of collateral to the borrower, lending agent or other
intermediary. Fees and expenses paid by the fund in connection with loans of
securities are not reflected in the fee table or expense example in the fund's
prospectus. If the income earned on the investment of the cash collateral is
insufficient to pay these amounts or if the value of the securities purchased
with such cash collateral declines, the fund may take a loss on the loan. Where
the fund receives securities as collateral, the fund will earn no income on the
collateral, but will earn a fee from the borrower. The fund reserves the right
to recall loaned securities so that it may exercise voting rights on loaned
securities according to the fund's Proxy Voting Policies and Procedures.

The risk in lending portfolio securities, as with other extensions of credit,
consists of the possibility of loss to the fund due to (i) the inability of the
borrower to return the securities, (ii) a delay in receiving additional
collateral to adequately cover any fluctuations in the value of securities on
loan, (iii) a delay in recovery of the securities, or (iv) the loss of rights
in the collateral should the borrower fail financially. In addition, as noted
above, the fund continues to have market risk and other risks associated with
owning the securities on loan. Where the collateral delivered by the borrower
is cash, the fund will also have the risk of loss of principal and interest in
connection with its investment of collateral. If a borrower defaults, the value
of the collateral may decline before the fund can dispose of it. The fund will
lend portfolio securities only to firms that have been approved in advance by
Pioneer, which will monitor the creditworthiness of any such firms. However,
this monitoring may not protect the fund from loss. At no time would the value
of the securities loaned exceed 33 1/3% of the value of the fund's total
assets.


INTERFUND LENDING
To satisfy redemption requests or to cover unanticipated cash shortfalls, a
fund may enter into lending agreements ("Interfund Lending Agreements") under
which the fund would lend money and borrow money for temporary purposes
directly to and from another Pioneer fund through a credit facility ("Interfund
Loan"), subject to meeting the conditions of an SEC exemptive order granted to
the funds permitting such interfund lending. All Interfund Loans will consist
only of uninvested cash reserves that the fund otherwise would invest in
short-term repurchase agreements or other short-term instruments.

If a fund has outstanding borrowings, any Interfund Loans to the fund (a) will
be at an interest rate equal to or lower than any outstanding bank loan, (b)
will be secured at least on an equal priority basis with at least an equivalent
percentage of collateral to loan value as any outstanding bank loan that
requires collateral, (c) will have a maturity no longer than any outstanding
bank loan (and in any event not over seven days) and (d) will provide that, if
an event of default occurs under any agreement evidencing an outstanding bank
loan to the fund, the event of default will automatically (without need for
action or notice by the lending fund) constitute an immediate event of default
under the Interfund Lending Agreement entitling the lending fund to call the
Interfund Loan (and exercise all rights with respect to any collateral) and
that such call will be made if the lending bank exercises its right to call its
loan under its agreement with the borrowing fund.


                                       36


A fund may make an unsecured borrowing through the credit facility if its
outstanding borrowings from all sources immediately after the interfund
borrowing total 10% or less of its total assets; provided, that if the fund has
a secured loan outstanding from any other lender, including but not limited to
another Pioneer fund, the fund's interfund borrowing will be secured on at
least an equal priority basis with at least an equivalent percentage of
collateral to loan value as any outstanding loan that requires collateral. If a
fund's total outstanding borrowings immediately after an interfund borrowing
would be greater than 10% of its total assets, the fund may borrow through the
credit facility on a secured basis only. A fund may not borrow through the
credit facility nor from any other source if its total outstanding borrowings
immediately after the interfund borrowing would be more than 33 1/3% of its
total assets.

No fund may lend to another fund through the interfund lending credit facility
if the loan would cause its aggregate outstanding loans through the credit
facility to exceed 15% of the lending fund's net assets at the time of the
loan. A fund's Interfund Loans to any one fund shall not exceed 5% of the
lending fund's net assets. The duration of Interfund Loans is limited to the
time required to receive payment for securities sold, but in no event more than
seven days. Loans effected within seven days of each other will be treated as
separate loan transactions for purposes of this condition. Each Interfund Loan
may be called on one business day's notice by a lending fund and may be repaid
on any day by a borrowing fund.

The limitations detailed above and the other conditions of the SEC exemptive
order permitting interfund lending are designed to minimize the risks
associated with interfund lending for both the lending fund and the borrowing
fund. However, no borrowing or lending activity is without risk. When a fund
borrows money from another fund, there is a risk that the loan could be called
on one day's notice or not renewed, in which case the fund may have to borrow
from a bank at higher rates if an Interfund Loan were not available from
another fund. A delay in repayment to a lending fund could result in a lost
opportunity or additional lending costs.


WHEN-ISSUED AND DELAYED DELIVERY SECURITIES
The fund may purchase securities, including U.S. government securities, on a
when-issued basis or may purchase or sell securities for delayed delivery. In
such transactions, delivery of the securities occurs beyond the normal
settlement period, but no payment or delivery is made by the fund prior to the
actual delivery or payment by the other party to the transaction. The fund will
not earn income on these securities until delivered. The purchase of securities
on a when-issued or delayed delivery basis involves the risk that the value of
the securities purchased will decline prior to the settlement date. The sale of
securities for delayed delivery involves the risk that the prices available in
the market on the delivery date may be greater than those obtained in the sale
transaction. When the fund enters into when-issued or delayed delivery
transactions it will segregate liquid assets with a value equal to the fund's
obligations. See "Asset Segregation."


DISCLOSURE OF PORTFOLIO HOLDINGS
The Board of Trustees has adopted policies and procedures relating to
disclosure of the Pioneer funds' portfolio securities. These policies and
procedures are designed to provide a framework for disclosing information
regarding portfolio holdings, portfolio composition or other portfolio
characteristics consistent with applicable federal securities laws and
regulations and general principles of fiduciary duty relating to fund
shareholders. While Pioneer may manage other separate accounts and unregistered
products that have substantially similar investment strategies to those of
another Pioneer fund, and therefore portfolio holdings that may be
substantially similar, and in some cases nearly identical, to such fund, these
policies and procedures only relate to the disclosure of portfolio information
of the Pioneer funds that are registered management companies. Separate account
and unregistered product clients are not subject to these policies and
procedures. Separate account and unregistered product clients of Pioneer have
access to their portfolio holdings, and prospective clients have access to
representative holdings.

Generally, Pioneer will make a fund's full portfolio information available to
the public on a monthly basis with an appropriate delay based upon the nature
of the information disclosed. Pioneer normally will publish a fund's full
portfolio holdings thirty (30) days after the end of each month (this time
period may be different for certain funds. Such information shall be made
available on the funds' website (us.pioneerinvestments.com)


                                       37


and may be sent to rating agencies, reporting/news services and financial
intermediaries, upon request. In addition, Pioneer generally makes publicly
available information regarding a fund's top ten holdings (including the
percentage of a fund's assets represented by each security), the percentage
breakdown of a fund's investments by country, sector and industry, various
volatility measures (such as beta, standard deviation, etc.), market
capitalization ranges and other portfolio characteristics (such as alpha,
average P/E ratio, etc.) three (3) business days after the end of each month.

Pioneer may provide a fund's full portfolio holdings or other information to
certain entities prior to the date such information is made public, provided
that certain conditions are met. The entities to which such disclosure may be
made as of the date of this statement of additional information are rating
agencies, plan sponsors, prospective separate account clients and other
financial intermediaries (i.e., organizations evaluating a fund for purposes of
investment by their clients, such as broker-dealers, investment advisers,
banks, insurance companies, financial planning firms, plan sponsors, plan
administrators, shareholder servicing organizations and pension consultants).
The third party must agree to a limited use of that information which does not
conflict with the interests of the fund's shareholders, to use the information
only for that authorized purpose, to keep such information confidential, and
not to trade on such information. The Board of Trustees considered the
disclosure of portfolio holdings information to these categories of entities to
be consistent with the best interests of shareholders in light of the agreement
to maintain the confidentiality of such information and only to use such
information for the limited and approved purposes. Pioneer's compliance
department, the local head of investment management and the global chief
investment officer may, but only acting jointly, grant exemptions to this
policy. Exemptions may be granted only if these persons determine that
providing such information is consistent with the interests of shareholders and
the third party agrees to limit the use of such information only for the
authorized purpose, to keep such information confidential, and not to trade on
such information. Although the Board of Trustees will periodically be informed
of exemptions granted, granting exemptions entails the risk that portfolio
holdings information may be provided to entities that use the information in a
manner inconsistent with their obligations and the best interests of a fund.

Currently, Pioneer, on behalf of the Pioneer funds, has ongoing arrangements
whereby the following entities may receive a fund's full portfolio holdings or
other information prior to the date such information is made public:
Metropolitan Life Insurance Company (within 30 days after month end for board
materials and advance preparation of marketing materials, as needed to evaluate
Pioneer funds); Roszel Advisors (within 30 days after month end for due
diligence and review of certain Pioneer funds included in fund programs);
Oppenheimer & Co. (within 30 days after month end for due diligence and review
of certain Pioneer funds included in fund programs); UBS (within 15 days after
month end for due diligence and review of certain Pioneer funds included in
fund programs); Beacon Pointe Advisors (as needed for quarterly review of
certain Pioneer funds); Commonwealth Financial Network (within 30 days after
month end for risk analysis on funds on behalf of their clients); Hartford
Retirement Services, LLC (as needed for risk analysis on funds on behalf of
their clients); Transamerica Life Insurance Company (as needed for performance
and risk analysis on funds on behalf of their clients); TIBCO Software
Inc./Spotfire Division (as needed to evaluate and develop portfolio reporting
software); Curcio Webb, LLC (as needed for evaluation and research purposes);
Fidelity Investments (as needed to evaluate Pioneer funds); Egan Jones Ratings
Company (as needed in order to evaluate and select Nationally Recognized
Statistical Rating Organizations (NRSROs)); DBRS Limited (as needed in order to
evaluate and select NRSROs); Wells Fargo Advisors (as needed for risk analysis
on funds on behalf of their clients and product review); and Capital Market
Consultants (as needed to complete quarterly due diligence research).

Compliance with the funds' portfolio holdings disclosure policy is subject to
periodic review by the Board of Trustees, including a review of any potential
conflicts of interest in the disclosures made by Pioneer in accordance with the
policy or the exceptions permitted under the policy. Any change to the policy
to expand


                                       38


the categories of entities to which portfolio holdings may be disclosed or an
increase in the purposes for which such disclosure may be made would be subject
to approval by the Board of Trustees and, reflected, if material, in a
supplement to the fund's statement of additional information.

The funds' full portfolio holdings disclosure policy is not intended to prevent
the disclosure of any and all portfolio information to the funds' service
providers who generally need access to such information in the performance of
their contractual duties and responsibilities, such as Pioneer, the funds'
custodian, fund accounting agent, principal underwriter, investment
sub-adviser, if any, independent registered public accounting firm or counsel.
In approving the policy, the Board of Trustees considered that the service
providers are subject to duties of confidentiality and duties not to trade on
non-public information arising under law or contract that provide an adequate
safeguard for such information. None of Pioneer, the funds, or any other party
receive any compensation or other consideration from any arrangement pertaining
to the release of a fund's full portfolio holdings information.

In addition, the funds make their portfolio holdings available semi-annually in
shareholder reports filed on Form N-CSR and after the first and third fiscal
quarters in regulatory filings on Form N-Q. These shareholder reports and
regulatory filings are filed with the SEC, as required by the federal
securities laws. Form N-Q is filed with the SEC within sixty (60) days after
the end of a fund's first and third fiscal quarters. Form N-CSR is filed with
the SEC within ten (10) days after the transmission to shareholders of a fund's
annual or semi-annual report, as applicable.


INVESTMENT RESTRICTIONS


FUNDAMENTAL INVESTMENT POLICIES
The fund has adopted certain fundamental investment policies which, along with
the fund's investment objective, may not be changed without the affirmative
vote of the holders of a "majority of the outstanding voting securities" (as
defined in the 1940 Act) of the fund. For this purpose, a majority of the
outstanding shares of the fund means the vote of the lesser of:

(1)   67% or more of the shares represented at a meeting, if the holders of
      more than 50% of the outstanding shares are present in person or by
      proxy; or

(2)   more than 50% of the outstanding shares of the fund.

The fund's fundamental policies are as follows:

(1)   The fund may not borrow money except as permitted by (i) the 1940 Act, or
      interpretations or modifications by the SEC, SEC staff or other authority
      of competent jurisdiction, or (ii) exemptive or other relief or
      permission from the SEC, SEC staff or other authority of competent
      jurisdiction.

(2)   The fund may not engage in the business of underwriting the securities of
      other issuers except as permitted by (i) the 1940 Act, or interpretations
      or modifications by the SEC, SEC staff or other authority of competent
      jurisdiction, or (ii) exemptive or other relief or permission from the
      SEC, SEC staff or other authority of competent jurisdiction.

(3)   The fund may lend money or other assets to the extent permitted by (i)
      the 1940 Act, or interpretations or modifications by the SEC, SEC staff
      or other authority of competent jurisdiction or (ii) exemptive or other
      relief or permission from the SEC, SEC staff or other authority of
      competent jurisdiction.

(4)   The fund may not issue senior securities except as permitted by (i) the
      1940 Act, or interpretations or modifications by the SEC, SEC staff or
      other authority of competent jurisdiction, or (ii) exemptive or other
      relief or permission from the SEC, SEC staff or other authority of
      competent jurisdiction.

(5)   The fund may not purchase or sell real estate except as permitted by (i)
      the 1940 Act, or interpretations or modifications by the SEC, SEC staff
      or other authority of competent jurisdiction, or (ii) exemptive or other
      relief or permission from the SEC, SEC staff or other authority of
      competent jurisdiction.


                                       39


(6)   The fund may purchase or sell commodities or contracts related to
      commodities to the extent permitted by (i) the 1940 Act, or
      interpretations or modifications by the SEC, SEC staff or other authority
      of competent jurisdiction, or (ii) exemptive or other relief or
      permission from the SEC, SEC staff or other authority of competent
      jurisdiction.

(7)   Except as permitted by exemptive or other relief or permission from the
      SEC, SEC staff or other authority of competent jurisdiction, the fund may
      not make any investment if, as a result, the fund's investments will be
      concentrated in any one industry.

With respect to the fundamental policy relating to borrowing money set forth in
(1) above, the 1940 Act permits a fund to borrow money in amounts of up to
one-third of the fund's total assets from banks for any purpose, and to borrow
up to 5% of the fund's total assets from banks or other lenders for temporary
purposes (the fund's total assets include the amounts being borrowed). To limit
the risks attendant to borrowing, the 1940 Act requires the fund to maintain at
all times an "asset coverage" of at least 300% of the amount of its borrowings.
Asset coverage means the ratio that the value of the fund's total assets
(including amounts borrowed), minus liabilities other than borrowings, bears to
the aggregate amount of all borrowings. Borrowing money to increase a fund's
investment portfolio is known as "leveraging." Borrowing, especially when used
for leverage, may cause the value of a fund's shares to be more volatile than
if the fund did not borrow. This is because borrowing tends to magnify the
effect of any increase or decrease in the value of the fund's portfolio
holdings. Borrowed money thus creates an opportunity for greater gains, but
also greater losses. To repay borrowings, the fund may have to sell securities
at a time and at a price that is unfavorable to the fund. There also are costs
associated with borrowing money, and these costs would offset and could
eliminate a fund's net investment income in any given period. Currently, the
fund does not contemplate borrowing for leverage, but if the fund does so, it
will not likely do so to a substantial degree. The policy in (1) above will be
interpreted to permit the fund to engage in trading practices and investments
that may be considered to be borrowing to the extent permitted by the 1940 Act.
Reverse repurchase agreements may be considered to be a type of borrowing.
Short-term credits necessary for the settlement of securities transactions and
arrangements with respect to securities lending will not be considered to be
borrowings under the policy. Practices and investments that may involve
leverage but are not considered to be borrowings are not subject to the policy.
Such trading practices may include futures, options on futures, forward
contracts and other derivative investments.

A fund may pledge its assets and guarantee the securities of another company
without limitation, subject to the fund's investment policies (including the
fund's fundamental policy regarding borrowing) and applicable laws and
interpretations. Pledges of assets and guarantees of obligations of others are
subject to many of the same risks associated with borrowings and, in addition,
are subject to the credit risk of the obligor for the underlying obligations.
To the extent that pledging or guaranteeing assets may be considered the
issuance of senior securities, the issuance of senior securities is governed by
the fund's policies on senior securities. If the fund were to pledge its
assets, the fund would take into account any then-applicable legal guidance,
including any applicable SEC staff position, would be guided by the judgment of
the fund's Board and Pioneer regarding the terms of any credit facility or
arrangement, including any collateral required, and would not pledge more
collateral than, in their judgment, is necessary for the fund to obtain the
credit sought. Shareholders should note that in 1973, the SEC staff took the
position in a no-action letter that a mutual fund could not pledge 100% of its
assets without a compelling business reason. In more recent no-action letters,
including letters that address the same statutory provision of the 1940 Act
(Section 17) addressed in the 1973 letter, the SEC staff has not mentioned any
limitation on the amount of collateral that may be pledged to support credit
obtained. This does not mean that the staff's position on this issue has
changed.

With respect to the fundamental policy relating to underwriting set forth in
(2) above, the 1940 Act does not prohibit a fund from engaging in the
underwriting business or from underwriting the securities of other issuers; in
fact, the 1940 Act permits a fund to have underwriting commitments of up to 25%
of its assets under certain circumstances. Those circumstances currently are
that the amount of the fund's underwriting commitments, when added to the value
of the fund's investments in issuers where the fund owns more


                                       40


than 10% of the outstanding voting securities of those issuers, cannot exceed
the 25% cap. A fund engaging in transactions involving the acquisition or
disposition of portfolio securities may be considered to be an underwriter
under the Securities Act of 1933, as amended (the "1933 Act"). Under the 1933
Act, an underwriter may be liable for material omissions or misstatements in an
issuer's registration statement or prospectus. Securities purchased from an
issuer and not registered for sale under the 1933 Act are considered restricted
securities. There may be a limited market for these securities. If these
securities are registered under the 1933 Act, they may then be eligible for
sale but participating in the sale may subject the seller to underwriter
liability. These risks could apply to a fund investing in restricted
securities. Although it is not believed that the application of the 1933 Act
provisions described above would cause a fund to be engaged in the business of
underwriting, the policy in (2) above will be interpreted not to prevent the
fund from engaging in transactions involving the acquisition or disposition of
portfolio securities, regardless of whether the fund may be considered to be an
underwriter under the 1933 Act.

With respect to the fundamental policy relating to lending set forth in (3)
above, the 1940 Act does not prohibit a fund from making loans; however, SEC
staff interpretations currently prohibit funds from lending more than one-third
of their total assets, except through the purchase of debt obligations or the
use of repurchase agreements. (A repurchase agreement is an agreement to
purchase a security, coupled with an agreement to sell that security back to
the original seller on an agreed-upon date at a price that reflects current
interest rates. The SEC frequently treats repurchase agreements as loans.)
While lending securities may be a source of income to a fund, as with other
extensions of credit, there are risks of delay in recovery or even loss of
rights in the underlying securities should the borrower fail financially.
However, loans would be made only when the fund's manager or a subadviser
believes the income justifies the attendant risks. The fund also will be
permitted by this policy to make loans of money, including to other funds. The
fund has obtained exemptive relief from the SEC to make short-term loans to
other Pioneer funds through a credit facility in order to satisfy redemption
requests or to cover unanticipated cash shortfalls; as discussed in this
Statement of Additional Information under "Interfund Lending". The conditions
of the SEC exemptive order permitting interfund lending are designed to
minimize the risks associated with interfund lending, however no lending
activity is without risk. A delay in repayment to a lending fund could result
in a lost opportunity or additional lending costs. The policy in (3) above will
be interpreted not to prevent the fund from purchasing or investing in debt
obligations and loans. In addition, collateral arrangements with respect to
options, forward currency and futures transactions and other derivative
instruments, as well as delays in the settlement of securities transactions,
will not be considered loans.

With respect to the fundamental policy relating to issuing senior securities
set forth in (4) above, "senior securities" are defined as fund obligations
that have a priority over the fund's shares with respect to the payment of
dividends or the distribution of fund assets. The 1940 Act prohibits a fund
from issuing senior securities except that the fund may borrow money in amounts
of up to one-third of the fund's total assets from banks for any purpose. A
fund also may borrow up to 5% of the fund's total assets from banks or other
lenders for temporary purposes, and these borrowings are not considered senior
securities. The issuance of senior securities by a fund can increase the
speculative character of the fund's outstanding shares through leveraging.
Leveraging of a fund's portfolio through the issuance of senior securities
magnifies the potential for gain or loss on monies, because even though the
fund's net assets remain the same, the total risk to investors is increased.
Certain widely used investment practices that involve a commitment by a fund to
deliver money or securities in the future are not considered by the SEC to be
senior securities, provided that a fund segregates cash or liquid securities in
an amount necessary to pay the obligation or the fund holds an offsetting
commitment from another party. These investment practices include repurchase
and reverse repurchase agreements, swaps, dollar rolls, options, futures and
forward contracts. The policy in (4) above will be interpreted not to prevent
collateral arrangements with respect to swaps, options, forward or futures
contracts or other derivatives, or the posting of initial or variation margin.


                                       41


With respect to the fundamental policy relating to real estate set forth in (5)
above, the 1940 Act does not prohibit a fund from owning real estate; however,
a fund is limited in the amount of illiquid assets it may purchase. Investing
in real estate may involve risks, including that real estate is generally
considered illiquid and may be difficult to value and sell. Owners of real
estate may be subject to various liabilities, including environmental
liabilities. To the extent that investments in real estate are considered
illiquid, the current SEC staff position generally limits a fund's purchases of
illiquid securities to 15% of net assets. The policy in (5) above will be
interpreted not to prevent the fund from investing in real estate-related
companies, companies whose businesses consist in whole or in part of investing
in real estate, instruments (like mortgages) that are secured by real estate or
interests therein, or real estate investment trust securities.

With respect to the fundamental policy relating to commodities set forth in (6)
above, the 1940 Act does not prohibit a fund from owning commodities, whether
physical commodities and contracts related to physical commodities (such as oil
or grains and related futures contracts), or financial commodities and
contracts related to financial commodities (such as currencies and, possibly,
currency futures). However, a fund is limited in the amount of illiquid assets
it may purchase. To the extent that investments in commodities are considered
illiquid, the current SEC staff position generally limits a fund's purchases of
illiquid securities to 15% of net assets. If a fund were to invest in a
physical commodity or a physical commodity-related instrument, the fund would
be subject to the additional risks of the particular physical commodity and its
related market. The value of commodities and commodity-related instruments may
be extremely volatile and may be affected either directly or indirectly by a
variety of factors. There also may be storage charges and risks of loss
associated with physical commodities. The policy in (6) above will be
interpreted to permit investments in exchange traded funds that invest in
physical and/or financial commodities.

With respect to the fundamental policy relating to concentration set forth in
(7) above, the 1940 Act does not define what constitutes "concentration" in an
industry. The SEC staff has taken the position that investment of 25% or more
of a fund's total assets in one or more issuers conducting their principal
activities in the same industry or group of industries constitutes
concentration. It is possible that interpretations of concentration could
change in the future. A fund that invests a significant percentage of its total
assets in a single industry may be particularly susceptible to adverse events
affecting that industry and may be more risky than a fund that does not
concentrate in an industry. The policy in (7) above will be interpreted to
refer to concentration as that term may be interpreted from time to time. The
policy also will be interpreted to permit investment without limit in the
following: securities of the U.S. government and its agencies or
instrumentalities; and repurchase agreements collateralized by any such
obligations. Accordingly, issuers of the foregoing securities will not be
considered to be members of any industry. The policy also will be interpreted
to give broad authority to the fund as to how to classify issuers within or
among industries. When identifying industries for purposes of its concentration
policy, the fund may rely upon available industry classifications. As of the
date of the SAI, the fund relies primarily on the Bloomberg L.P. ("Bloomberg")
classifications, and, with respect to securities for which no industry
classification under Bloomberg is available or for which the Bloomberg
classification is determined not to be appropriate, the fund may use industry
classifications published by another source, which, as of the date of the SAI,
is MSCI Global Industry Classification Standard. As of the date of the SAI, the
fund's adviser may assign an industry classification for an exchange-traded
fund in which the fund invests based on the constituents of the index on which
the exchange-traded fund is based. The fund may change any source used for
determining industry classifications without shareholder approval.

The fund's fundamental policies are written and will be interpreted broadly.
For example, the policies will be interpreted to refer to the 1940 Act and the
related rules as they are in effect from time to time, and to interpretations
and modifications of or relating to the 1940 Act by the SEC, SEC staff or other
authority of competent jurisdiction as they are given from time to time. When a
policy provides that an investment practice may be conducted as permitted by
the 1940 Act, the policy will be interpreted to mean either that the 1940 Act
expressly permits the practice or that the 1940 Act does not prohibit the
practice.


                                       42


The fund's non-fundamental investment policies may be changed by a vote of the
Board of Trustees without approval of shareholders at any time.


NON-FUNDAMENTAL INVESTMENT POLICY
The following policy is non-fundamental and may be changed by a vote of the
Board of Trustees without approval of shareholders.

The fund may not invest in any investment company in reliance on Section
12(d)(1)(F) of the 1940 Act, which would allow the fund to invest in other
investment companies, or in reliance on Section 12(d)(1)(G) of the 1940 Act,
which would allow the fund to invest in other Pioneer funds, in each case
without being subject to the limitations discussed above under "Other
Investment Companies" so long as another investment company invests in the fund
in reliance on Section 12(d)(1)(G). The fund has adopted this non-fundamental
policy in order that the fund may be a permitted investment of the series of
Pioneer Ibbotson Asset Allocation Series and Pioneer Ibbotson Asset Allocation
Series VCT Portfolios, which invest all of their assets in other investment
companies. If the series of Pioneer Ibbotson Asset Allocation Series or Pioneer
Ibbotson Asset Allocation Series VCT Portfolios do not invest in the fund, then
this non-fundamental restriction will not apply.


DIVERSIFICATION
The fund is currently classified as a diversified fund under the 1940 Act. A
diversified fund may not purchase securities of an issuer (other than
obligations issued or guaranteed by the U.S. government, its agencies or
instrumentalities) if, with respect to 75% of the fund's total assets, (a) more
than 5% of the fund's total assets would be invested in securities of that
issuer, or (b) the fund would hold more than 10% of the outstanding voting
securities of that issuer. Under the 1940 Act, the fund cannot change its
classification from diversified to non-diversified without shareholder
approval.

Trustee; as to each Independent Trustee, his or her status as not being an
"interested person" as defined under the 1940 Act; and, as to Mr. Taubes, his
association with Pioneer. Each of the Independent Trustees also was selected to
join the Board based on the criteria and principles set forth in the Nominating

fund's business as a Trustee also are considered. In addition, the following

business experience as an executive officer and experience as a board member of
other organizations; Ms. Piret, accounting, financial and entrepreneurial
experience as an executive, valuation experience and investment company board
experience; Mr. Ricciardi, financial, business and investment company
experience as an executive officer of a financial and investment company
services organization, and experience as a board member of offshore investment
companies and other organizations; and Mr. Taubes, portfolio management
experience and leadership roles with Pioneer. However, in its periodic
assessment of the effectiveness of the Board, the Board considers the
complementary skills and experience of individual Trustees primarily in the
broader context of the Board's overall composition so that the Board, as a
body, possesses the appropriate (and appropriately diverse) skills and
experience to oversee the business of the fund.

The Trust's Amended and Restated Agreement and Declaration of Trust provides
that the appointment, designation (including in any proxy or registration
statement or other document) of a Trustee as an expert on any topic or in any
area, or as having experience, attributes or skills in any area, or any other
appointment, designation or identification, shall not impose on that person any
standard of care or liability that is greater than that imposed on that person
as a Trustee in the absence of the appointment, designation or identification,
and no Trustee who has special attributes, skills, experience or expertise, or
is appointed, designated, or identified as aforesaid, shall be held to a higher
standard of care by virtue thereof.

The Board of Trustees has five standing committees: the Independent Trustees
Committee, the Audit Committee, the Governance and Nominating Committee, the
Policy Administration Committee and the Valuation Committee. Each committee is
chaired by an Independent Trustee and all members of each committee are
Independent Trustees.

The Chairs of the committees work with the Chairman of the Board and fund
management in setting the agendas for Board meetings. The Chairs of the
committees set the agendas for committee meetings with input from fund
management. As noted below, through the committees, the Independent Trustees
consider and address important matters involving the fund, including those
presenting conflicts or potential conflicts of interest for management. The
Independent Trustees also regularly meet without the presence of management and
are advised by independent legal counsel. The Board has determined that
delegation to the committees of specified oversight responsibilities helps
ensure that the fund has effective and independent governance and oversight.
Notwithstanding the fact that the Chairman of the Board is an Independent
Trustee, the Board continues to believe that the committee structure enables
the Board more effectively to provide governance and oversight of the fund's
affairs. Mr. Perna, Chairman of the Board, is a member of each committee except
the Audit Committee and the Valuation Committee, of each of which he is a
non-voting, ex-officio member.

During the most recent fiscal year, the Independent Trustees, Audit, Governance
and Nominating, Policy Administration, and Valuation Committees held 8, 6, 2, 4
and 5 meetings, respectively.


INDEPENDENT TRUSTEES COMMITTEE
David R. Bock, Benjamin M. Friedman, Margaret B.W. Graham, Thomas J. Perna
(Chair), Marguerite A. Piret and Fred J. Ricciardi.

The Independent Trustees Committee is comprised of all of the Independent
Trustees. The Independent Trustees Committee serves as the forum for
consideration of a number of issues required to be considered separately by the
Independent Trustees under the 1940 Act, including the assessment and review of
the fund's advisory agreement and other related party contracts. The
Independent Trustees Committee also considers issues that the Independent
Trustees believe it is advisable for them to consider separately from the
Interested Trustees.


                                       48


AUDIT COMMITTEE
David R. Bock (Chair), Benjamin M. Friedman and Marguerite A. Piret.

The Audit Committee, among other things, oversees the accounting and financial
reporting policies and practices of the fund, oversees the quality and
integrity of the fund's financial statements, approves, and recommends to the
Independent Trustees for their ratification, the engagement of the fund's
independent registered public accounting firm, reviews and evaluates the
accounting firm's qualifications, independence and performance, and approves
the compensation of the accounting firm. The Audit Committee also approves all
audit and permissible non-audit services provided to the fund by the fund's
accounting firm and all permissible non-audit services provided by the fund's
accounting firm to Pioneer and any affiliated service providers of the fund if
the engagement relates directly to the fund's operations and financial
reporting.


GOVERNANCE AND NOMINATING COMMITTEE
Margaret B.W. Graham (Chair) and Thomas J. Perna.

The Governance and Nominating Committee considers governance matters affecting
the Board and the fund. Among other responsibilities, the Governance and
Nominating Committee reviews the performance of the Independent Trustees as a
whole, and reviews and recommends to the Independent Trustees Committee any
appropriate changes concerning, among other things, the size and composition of
the Board, the Board's committee structure and the Independent Trustees'
compensation. The Governance and Nominating Committee also makes
recommendations to the Independent Trustees Committee or the Board on matters
delegated to it.

In addition, the Governance and Nominating Committee screens potential
candidates for Independent Trustees. Among other responsibilities, the
Governance and Nominating Committee reviews periodically the criteria for
Independent Trustees and the spectrum of desirable experience and expertise for
Independent Trustees as a whole, and reviews periodically the qualifications
and requisite skills of persons currently serving as Independent Trustees and
being considered for re-nomination. The Governance and Nominating Committee
also reviews the qualifications of any person nominated to serve on the Board
by a shareholder or recommended by any Trustee, management or another person
and makes a recommendation as to the qualifications of such nominated or
recommended person to the Independent Trustees and the Board, and reviews
periodically the Committee's procedure, if any, regarding candidates submitted
by shareholders. The Governance and Nominating Committee does not have
specific, minimum qualifications for nominees, nor has it established specific
qualities or skills that it regards as necessary for one or more of the
Independent Trustees to possess (other than qualities or skills that may be
required by applicable law or regulation). However, in evaluating a person as a
potential nominee to serve as an Independent Trustee, the Governance and
Nominating Committee will consider the following general criteria and
principles, among any others that it may deem relevant:

o whether the person has a reputation for integrity, honesty and adherence to
  high ethical standards;

o whether the person has demonstrated business acumen and ability to exercise
  sound judgment in matters that relate to the objectives of the fund and
  whether the person is willing and able to contribute positively to the
  decision-making process of the fund;

o whether the person has a commitment and ability to devote the necessary time
  and energy to be an effective Independent Trustee, to understand the fund
  and the responsibilities of a trustee of an investment company;

o whether the person has the ability to understand the sometimes conflicting
  interests of the various constituencies of the fund and to act in the
  interests of all shareholders;

o whether the person has a conflict of interest that would impair his or her
  ability to represent the interests of all shareholders and to fulfill the
  responsibilities of a trustee; and


                                       49


o the value of diversity on the Board. The Governance and Nominating Committee
  Charter provides that nominees shall not be discriminated against on the
  basis of race, religion, national origin, sex, sexual orientation,
  disability or any other basis proscribed by law.

The Governance and Nominating Committee also will consider whether the nominee
has the experience or skills that the Governance and Nominating Committee
believes would maintain or enhance the effectiveness of the Independent
Trustees' oversight of the fund's affairs, based on the then current
composition and skills of the Independent Trustees and experience or skills
that may be appropriate in light of changing business conditions and regulatory
or other developments. The Governance and Nominating Committee does not
necessarily place the same emphasis on each criterion.

The Governance and Nominating Committee does not have a formal policy for
considering trustee nominees submitted by the fund's shareholders. Nonetheless,
the Nominating Committee may, on an informal basis, consider any shareholder
recommendations of nominees that it receives. Shareholders who wish to
recommend a nominee should send recommendations to the fund's Secretary that
include all information relating to such persons that is required to be
included in solicitations of proxies for the election of trustees.


POLICY ADMINISTRATION COMMITTEE
Margaret B.W. Graham (Chair), Thomas J. Perna, and Fred J. Ricciardi.

The Policy Administration Committee, among other things, oversees and monitors
the fund's compliance with legal and regulatory requirements that are not
directly related to financial reporting, internal financial controls,
independent audits or the performance of the fund's internal audit function.
The Policy Administration Committee also oversees the adoption and
implementation of certain of the fund's policies and procedures.


VALUATION COMMITTEE
David R. Bock, Benjamin M. Friedman and Marguerite A. Piret (Chair).

The Valuation Committee, among other things, determines with Pioneer the value
of securities under certain circumstances and considers other matters with
respect to the valuation of securities, in each case in accordance with the
fund's valuation procedures.


OVERSIGHT OF RISK MANAGEMENT
Consistent with its responsibility for oversight of the fund in the interests
of shareholders, the Board of Trustees oversees risk management of the fund's
investment management and business operations. In performing this oversight
function, the Board considers various risks and risk management practices
relating to the fund. The Board has delegated certain aspects of its risk
oversight responsibilities to the committees.

The fund faces a number of risks, such as investment risk, counterparty risk,
valuation risk, enterprise risk, reputational risk, cybersecurity risk, risk of
operational failure or lack of business continuity, and legal, compliance and
regulatory risk. The goal of risk management is to identify and address risks,
i.e., events or circumstances that could have material adverse effects on the
business, operations, shareholder services, investment performance or
reputation of the fund.

Most of the fund's investment management and business operations are carried
out by or through Pioneer, its affiliates, and other service providers, each of
which has an independent interest in risk management but whose policies and the
methods by which one or more risk management functions are carried out may
differ from the fund's and each other's in the setting of priorities, the
resources available or the effectiveness of relevant controls.

Under the overall supervision of the Board or the applicable committee of the
Board, the fund, or Pioneer and the affiliates of Pioneer or other service
providers to the fund employ a variety of processes, procedures and controls in
an effort to identify, address and mitigate risks. Different processes,
procedures and controls are employed with respect to different types of risks.
Various personnel, including the fund's and Pioneer's chief compliance officer
and Pioneer's chief risk officer and director of internal audit, as well as


                                       50


various personnel of Pioneer and of other service providers, make periodic
reports to the applicable committee or to the Board with respect to various
aspects of risk management. The reports received by the Trustees related to
risks typically are summaries of relevant information. During the course of the
most recent fiscal year, the Trustees increased the number of presentations
from the directors of Internal Audit and Risk Management at Pioneer, as well as
the Chief Operating Officer to whom they report, concerning the results and
process of their responsibilities.

The Trustees recognize that not all risks that may affect the fund can be
identified, that it may not be practical or cost-effective to eliminate or
mitigate certain risks, that it may be necessary to bear certain risks (such as
investment-related risks) to achieve the fund's goals, that the processes,
procedures and controls employed to address certain risks may be limited in
their effectiveness, and that some risks are simply beyond the control of the
fund or Pioneer and its affiliates or other service providers. As a result of
the foregoing and other factors, the fund's ability to manage risk is subject
to substantial limitations.

In addition, it is important to note that the fund is designed for investors
that are prepared to accept investment risk, including the possibility that as
yet unforeseen risks may emerge in the future.


COMPENSATION OF OFFICERS AND TRUSTEES
The Pioneer Funds, including the fund, compensate their Trustees. The
Independent Trustees review and set their compensation annually, taking into
consideration the committee and other responsibilities assigned to specific
Trustees. The table under "Annual Fees, Expense and Other Information -
Compensation of Officers and Trustees" sets forth the compensation paid to each
of the Trustees. The compensation paid to the Trustees is then allocated among
the funds as follows:

o each fund with assets less than $250 million pays each Independent Trustee an
  annual fee of $1,000.

o the remaining compensation of the Independent Trustees is allocated to each
  fund with assets greater than $250 million based on the fund's net assets.

o the Interested Trustees receive an annual fee of $500 from each fund, except
  in the case of funds with net assets of $50 million or less, which pay each
  Interested Trustee an annual fee of $200. Pioneer reimburses these funds for
  the fees paid to the Interested Trustees.

Except for the chief compliance officer, the fund does not pay any salary or
other compensation to its officers. The fund pays a portion of the chief
compliance officer's compensation for her services as the fund's chief
compliance officer. Pioneer pays the remaining portion of the chief compliance
officer's compensation.

See "Compensation of Officers and Trustees" in "Annual Fee, Expense and Other
Information."


SALES LOADS
The fund offers its shares to Trustees and officers of the fund and employees
of Pioneer and its affiliates without a sales charge in order to encourage
investment in the fund by individuals who are responsible for its management
and because the sales to such persons do not entail any sales effort by the
fund, brokers or other intermediaries.


OTHER INFORMATION
The Amended and Restated Agreement and Declaration of Trust provides that no
Trustee, officer or employee of the fund shall be liable to the fund or any
shareholder for any action, failure to act, error or mistake except in cases of
bad faith, willful misfeasance, gross negligence or reckless disregard of duty.
The Amended and Restated Agreement and Declaration of Trust requires the fund
to indemnify each Trustee, director, officer, employee and authorized agent to
the fullest extent permitted by law against liability and against all expenses
reasonably incurred or paid by him in connection with any claim, action, suit
or proceeding in which he becomes involved as a party or otherwise by virtue of
his being or having been such a Trustee, director, officer, employee, or agent
and against amounts paid or incurred by him in settlement thereof. The 1940 Act
currently provides that no officer or director shall be protected from
liability to the fund or


                                       51


shareholders for willful misfeasance, bad faith, gross negligence, or reckless
disregard of the duties of office. The Amended and Restated Agreement and
Declaration of Trust extends to Trustees, officers and employees of the fund
the full protection from liability that the law allows.


MATERIAL RELATIONSHIPS OF THE INDEPENDENT TRUSTEES
Steven K. West, who retired as an Independent Trustee on July 15, 2014, is
Senior Counsel to Sullivan & Cromwell, which acts as counsel to the Independent
Trustees and the Independent Trustees of the other Pioneer Funds. The aggregate
compensation paid to Sullivan & Cromwell by the fund and the other Pioneer
Funds was approximately $445,775 and $279,743 in each of 2013 and 2014.


SHARE OWNERSHIP
See "Annual Fee, Expense and Other Information" for information on the
ownership of fund shares by the Trustees, the fund's officers and owners in
excess of 5% of any class of shares of the fund and a table indicating the
value of shares that each Trustee beneficially owns in the fund and in all the
Pioneer Funds.


PROXY VOTING POLICIES
Information regarding how the fund voted proxies relating to portfolio
securities during the most recent 12-month period ended June 30 is available to
shareowners without charge at http://us.pioneerinvestments.com and on the SEC's
website at http://www.sec.gov. The fund's proxy voting policies and procedures
are attached as "Appendix B".


4. INVESTMENT ADVISER

The fund has entered into an amended and restated management agreement
(hereinafter, the "management contract") with Pioneer pursuant to which Pioneer
acts as the fund's investment adviser. Pioneer is an indirect, wholly owned
subsidiary of UniCredit. Certain Trustees or officers of the fund are also
directors and/or officers of certain of UniCredit's subsidiaries (see
management biographies above). Pioneer has entered into an agreement with its
affiliate, Pioneer Investment Management Limited ("PIML"), pursuant to which
PIML provides certain services to Pioneer.

As the fund's investment adviser, Pioneer provides the fund with investment
research, advice and supervision and furnishes an investment program for the
fund consistent with the fund's investment objective and policies, subject to
the supervision of the fund's Trustees. Pioneer determines what portfolio
securities will be purchased or sold, arranges for the placing of orders for
the purchase or sale of portfolio securities, selects brokers or dealers to
place those orders, maintains books and records with respect to the fund's
securities transactions, and reports to the Trustees on the fund's investments
and performance.

The management contract will continue in effect from year to year provided such
continuance is specifically approved at least annually (i) by the Trustees of
the fund or by a majority of the outstanding voting securities of the fund (as
defined in the 1940 Act), and (ii) in either event, by a majority of the
Independent Trustees of the fund, with such Independent Trustees casting votes
in person at a meeting called for such purpose.

The management contract may be terminated without penalty by the Trustees of
the fund or by vote of a majority of the outstanding voting securities of the
fund on not more than 60 days' nor less than 30 days' written notice to
Pioneer, or by Pioneer on not less than 90 days' written notice to the fund,
and will automatically terminate in the event of its assignment (as defined in
the 1940 Act) by Pioneer. The management contract is not assignable by the fund
except with the consent of Pioneer.

The Trustees' approval of and the terms, continuance and termination of the
management contract are governed by the 1940 Act. Pursuant to the management
contract, Pioneer assumes no responsibility other than to render the services
called for under the management contract, in good faith, and Pioneer will not
be liable for any error of judgment or mistake of law or for any loss arising
out of any investment or for any act or omission in the execution of securities
or other transactions for the fund. Pioneer, however, is not protected against
liability by reason of willful misfeasance, bad faith or gross negligence in
the performance


                                       52


of its duties or by reason of its reckless disregard of its obligations and
duties under the management contract. The management contract requires Pioneer
to furnish all necessary services, facilities and personnel in connection with
the performance of its services under the management contract, and except as
specifically stated therein, Pioneer is not responsible for any of the fund's
ordinary and extraordinary expenses.


ADVISORY FEE
As compensation for its management services and expenses incurred, the fund
pays Pioneer a fee at the annual rate of 0.40% of the fund's average daily net
assets. This fee is computed and accrued daily and paid monthly.

See the table in Annual Fee, Expense and Other Information for management fees
paid to Pioneer during recently completed fiscal years.


EXPENSE LIMITATION
Pioneer has contractually agreed to limit ordinary operating expenses (ordinary
operating expenses means all fund expenses other than extraordinary expenses,
such as litigation, taxes and brokerage commissions) to the extent required to
reduce fund expenses to 0.85%, 1.10% and 0.58% of the average daily net assets
attributable to Class A, Class R and Class Y shares, respectively. These
expense limitations are in effect through November 1, 2017. However, there can
be no assurance that Pioneer will extend the expense limitation beyond these
dates. While in effect, the arrangement may be terminated for a class only by
agreement of Pioneer and the Board of Trustees.


ADMINISTRATION AGREEMENT
The fund has entered into an amended and restated administration agreement with
Pioneer pursuant to which Pioneer acts as the fund's administrator, performing
certain accounting, administration and legal services for the fund. Pioneer is
reimbursed for its cost of providing such services. The cost of providing these
services is based on direct costs and costs of overhead, subject to review by
the Board of Trustees. See "Annual Fee, Expense and Other Information" for fees
the fund paid to Pioneer for administration and related services. In addition,
Brown Brothers Harriman & Co. performs certain sub-administration services to
the fund pursuant to an agreement with Pioneer and the fund.

Under the terms of the amended and restated administration agreement with the
fund, Pioneer pays or reimburses the fund for expenses relating to its services
for the fund, with the exception of the following, which are to be paid by the
fund: (a) charges and expenses for fund accounting, pricing and appraisal
services and related overhead, including, to the extent such services are
performed by personnel of Pioneer, or its affiliates, office space and
facilities and personnel compensation, training and benefits; (b) the charges
and expenses of auditors; (c) the charges and expenses of any custodian,
transfer agent, plan agent, dividend disbursing agent and registrar appointed
by the fund; (d) issue and transfer taxes, chargeable to the fund in connection
with securities transactions to which the fund is a party; (e) insurance
premiums, interest charges, dues and fees for membership in trade associations
and all taxes and corporate fees payable by the fund to federal, state or other
governmental agencies; (f) fees and expenses involved in registering and
maintaining registrations of the fund and/or its shares with federal regulatory
agencies, state or blue sky securities agencies and foreign jurisdictions,
including the preparation of prospectuses and statements of additional
information for filing with such regulatory authorities; (g) all expenses of
shareholders' and Trustees' meetings and of preparing, printing and
distributing prospectuses, notices, proxy statements and all reports to
shareholders and to governmental agencies; (h) charges and expenses of legal
counsel to the fund and the Trustees; (i) any distribution fees paid by the
fund in accordance with Rule 12b-1 promulgated by the SEC pursuant to the 1940
Act; (j) compensation of those Trustees of the fund who are not affiliated with
or interested persons of Pioneer, the fund (other than as Trustees), PIM-USA or
PFD; (k) the cost of preparing and printing share certificates; (l) interest on
borrowed money, if any; (m) fees payable by the fund under management
agreements and the administration agreement; and


                                       53


(n) extraordinary expenses. The fund shall also assume and pay any other
expense that the fund, Pioneer or any other agent of the fund may incur not
listed above that is approved by the Board of Trustees (including a majority of
the Independent Trustees) as being an appropriate expense of the fund. The fund
shall pay all fees and expenses to be paid by the fund under the
sub-administration agreement with Brown Brothers Harriman & Co. In addition,
the fund shall pay all brokers' and underwriting commissions chargeable to the
fund in connection with securities transactions to which the fund is a party.


POTENTIAL CONFLICTS OF INTEREST
The fund is managed by Pioneer, which also serves as investment adviser to
other Pioneer mutual funds and other accounts (including separate accounts and
unregistered products) with investment objectives identical or similar to those
of the fund. Securities frequently meet the investment objectives of the fund,
the other Pioneer mutual funds and such other accounts. In such cases, the
decision to recommend a purchase to one fund or account rather than another is
based on a number of factors. The determining factors in most cases are the
amount of securities of the issuer then outstanding, the value of those
securities and the market for them. Other factors considered in the investment
recommendations include other investments which each fund or account presently
has in a particular industry and the availability of investment funds in each
fund or account.

It is possible that at times identical securities will be held by more than one
fund and/or account. However, positions in the same issue may vary and the
length of time that any fund or account may choose to hold its investment in
the same issue may likewise vary. To the extent that more than one of the
Pioneer mutual funds or a private account managed by Pioneer seeks to acquire
the same security at about the same time, the fund may not be able to acquire
as large a position in such security as it desires or it may have to pay a
higher price for the security. Similarly, the fund may not be able to obtain as
large an execution of an order to sell or as high a price for any particular
portfolio security if Pioneer decides to sell on behalf of another account the
same portfolio security at the same time. On the other hand, if the same
securities are bought or sold at the same time by more than one fund or
account, the resulting participation in volume transactions could produce
better executions for the fund. In the event more than one account purchases or
sells the same security on a given date, the purchases and sales will normally
be made as nearly as practicable on a pro rata basis in proportion to the
amounts desired to be purchased or sold by each account. Although the other
Pioneer mutual funds may have the same or similar investment objectives and
policies as the fund, their portfolios do not generally consist of the same
investments as the fund or each other, and their performance results are likely
to differ from those of the fund.


PERSONAL SECURITIES TRANSACTIONS
The fund, Pioneer, and PFD have adopted a code of ethics under Rule 17j-1 under
the 1940 Act which is applicable to officers, trustees/directors and designated
employees of Pioneer and certain of Pioneer's affiliates. The code permits such
persons to engage in personal securities transactions for their own accounts,
including securities that may be purchased or held by the fund, and is designed
to prescribe means reasonably necessary to prevent conflicts of interest from
arising in connection with personal securities transactions. The code is on
public file with and available from the SEC.


5. PRINCIPAL UNDERWRITER AND DISTRIBUTION PLAN


PRINCIPAL UNDERWRITER
PFD, 60 State Street, Boston, Massachusetts 02109, is the principal underwriter
for the fund in connection with the continuous offering of its shares. PFD is
an indirect wholly owned subsidiary of PIM-USA.

The fund entered into an underwriting agreement with PFD which provides that
PFD will bear expenses for the distribution of the fund's shares, except for
expenses incurred by PFD for which it is reimbursed or compensated by the fund
under the distribution plan (discussed below). PFD bears all expenses it incurs


                                       54


in providing services under the underwriting agreement. Such expenses include
compensation to its employees and representatives and to securities dealers for
distribution-related services performed for the fund. PFD also pays certain
expenses in connection with the distribution of the fund's shares, including
the cost of preparing, printing and distributing advertising or promotional
materials, and the cost of printing and distributing prospectuses and
supplements to prospective shareholders. The fund bears the cost of registering
its shares under federal and state securities law and the laws of certain
non-U.S. countries. Under the underwriting agreement, PFD will use its best
efforts in rendering services to the fund.

See "Sales Charges" for the schedule of initial sales charge reallowed to
dealers as a percentage of the offering price of the fund's Class A shares.

See the tables under "Annual Fee, Expense and Other Information" for
commissions retained by PFD and reallowed to dealers in connection with PFD's
offering of the fund's Class A and Class C shares during recently completed
fiscal years.

The fund will not generally issue fund shares for consideration other than
cash. At the fund's sole discretion, however, it may issue fund shares for
consideration other than cash in connection with a bona fide reorganization,
statutory merger or other acquisition of portfolio securities.

It is the fund's general practice to repurchase its shares of beneficial
interest for cash consideration in any amount; however, the redemption price of
shares of the fund may, at Pioneer's discretion, be paid in portfolio
securities. The fund has elected to be governed by Rule 18f-1 under the 1940
Act pursuant to which the fund is obligated to redeem shares solely in cash up
to the lesser of $250,000 or 1% of the fund's net asset value during any 90-day
period for any one shareholder. Should the amount of redemptions by any
shareholder exceed such limitation, the fund will have the option of redeeming
the excess in cash or portfolio securities. In the latter case, the securities
are taken at their value employed in determining the fund's net asset value.
You may incur additional costs, such as brokerage fees and taxes, and risks,
including a decline in the value of the securities you receive, if the fund
makes an in-kind distribution.


DISTRIBUTION PLAN
The fund has adopted a distribution plan (the "Distribution Plan") pursuant to
Rule 12b-1 under the 1940 Act with respect to its Class A, Class C and Class R
shares. The fund has not adopted a Distribution Plan with respect to its Class
K or Class Y shares.

For each Class that has adopted a Distribution Plan, fees under the
Distribution Plan may be used to make payments to one or more principal
underwriters, broker-dealers, financial intermediaries (which may include
banks) and other parties that enter into a distribution, selling or service
agreement with respect to the shares of such Class (each of the foregoing, a
"Service Party"). The fund, its principal underwriter or other parties also may
incur expenses in connection with the distribution or marketing and sales of
the fund's shares that may be paid or reimbursed by the fund. The aggregate
amount in respect of such fees and expenses with respect to each Class shall be
the amount calculated at a percentage per annum of the average daily net assets
attributable to such Class as set forth below:




            APPLICABLE PERCENTAGE
CLASS                   PER ANNUM
---------  ----------------------
        
Class A                    0.25%
---------                   ----
Class C                    1.00%
---------                   ----
Class R                    0.50%
---------                   ----


Payments are made under the Distribution Plan for distribution services and
other activities in respect of the sale of shares of the fund and to make
payments for advertising, marketing or other promotional activity, and for
preparation, printing, and distribution of prospectuses, statements of
additional information and reports for recipients other than regulators and
existing shareholders. The fund also may make payments to Service Parties under
the Distribution Plan for providing personal service or the


                                       55


maintenance of shareholder accounts. The amounts paid to each recipient may
vary based upon certain factors, including, among other things, the levels of
sales of fund shares and/or shareholder services provided; provided, however,
that the fees paid to a recipient with respect to a particular Class that may
be used to cover expenses primarily intended to result in the sale of shares of
that Class, or that may be used to cover expenses primarily intended for
personal service and/or maintenance of shareholder accounts, may not exceed the
maximum amounts, if any, as may from time to time be permitted for such
services under the Financial Industry Regulatory Authority ("FINRA") Conduct
Rule 2830 or any successor rule, in each case as amended or interpreted by
FINRA.

The Distribution Plan also provides that the Service Parties may receive all or
a portion of any sales charges paid by investors.

The Distribution Plan permits the fund to pay fees to the Service Parties as
compensation for their services, not as reimbursement for specific expenses
incurred. Thus, even if their expenses exceed the fees provided for by the
Distribution Plan, the fund will not be obligated to pay more than those fees
and, if their expenses are less than the fees paid to them, they will realize a
profit. The fund may pay the fees to the Service Parties until the Distribution
Plan or any related distribution agreement is terminated or not renewed. In
that event, a Service Party's expenses in excess of fees received or accrued
through the termination date will be such Service Party's sole responsibility
and not obligations of the fund. In their annual consideration of the
continuation of the Distribution Plan for the fund, the Trustees will review
the Distribution Plan and the expenses for each Class within the fund
separately. The fund may participate in joint distribution activities with
other Pioneer funds. The costs associated with such joint distribution
activities are allocated to a fund based on the number of shares sold.

The Distribution Plan also recognizes that Pioneer, PFD or any other Service
Party may make payments for distribution-related expenses out of its own
resources, including past profits, or payments received from the fund for other
purposes, such as management fees, and that the Service Parties may from time
to time use their own resources for distribution-related services, in addition
to the fees paid under the Distribution Plan. The Distribution Plan
specifically provides that, to the extent that such payments might be deemed to
be indirect financing of any activity primarily intended to result in the sale
of shares of the fund within the context of Rule 12b-1, then the payments are
deemed to be authorized by the Distribution Plan but not subject to the maximum
amounts set forth above.

Under its terms, the Distribution Plan continues in effect for one year and
thereafter for successive annual periods, provided such continuance is
specifically approved at least annually by vote of the Board, including a
majority of the Independent Trustees who have no direct or indirect financial
interest in the operation of the Distribution Plan. The Distribution Plan may
not be amended to increase materially the amount of the service and
distribution fees without shareholder approval, and all material amendments of
the Distribution Plan also must be approved by the Trustees, including all of
the Independent Trustees, in the manner described above. The Distribution Plan
may be terminated with respect to a Class of the fund at any time, without
penalty, by vote of a majority of the Independent Trustees or by vote of a
majority of the outstanding voting securities of such Class of the fund (as
defined in the 1940 Act).

See "Annual Fee, Expense and Other Information" for fund expenses under the
Distribution Plan paid to PFD for the most recently completed fiscal year.


CLASS C SHARES
PFD will advance to dealers the first-year service fee at a rate equal to 0.25%
of the amount invested. As compensation therefor, PFD may retain the service
fee paid by the fund with respect to such shares for the first year after
purchase. Commencing in the 13th month following the purchase of Class C
shares, dealers will become eligible for additional annual distribution fees
and service fees of up to 0.75% and 0.25%, respectively, of the net asset value
of such shares. Dealers may from time to time be required to meet certain other
criteria in order to receive service fees.


                                       56


SERVICE PLAN FOR CLASS R SHARES
The fund has adopted a service plan (the "Service Plan") with respect to its
Class R shares under which the fund is authorized to pay securities dealers,
plan administrators or other service organizations who agree to provide certain
services to 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 plan participants. These services may include (a) acting,
directly or through an agent, as the shareholder of record and nominee for all
plan participants, (b) maintaining account records for each plan participant
that beneficially owns Class R shares, (c) processing orders to purchase,
redeem and exchange Class R shares on behalf of plan participants, and handling

POTENTIAL CONFLICTS OF INTEREST
When a portfolio manager is responsible for the management of more than one
account, the potential arises for the portfolio manager to favor one account
over another. The principal types of potential conflicts of interest that may
arise are discussed below. For the reasons outlined below, Pioneer does not
believe that any material conflicts are likely to arise out of a portfolio
manager's responsibility for the management of the fund as well as one or more
other accounts. Although Pioneer has adopted procedures that it believes are
reasonably designed to detect and prevent violations of the federal securities
laws and to mitigate the potential for conflicts of interest to affect its
portfolio management decisions, there can be no assurance that all conflicts
will be identified or that all procedures will be effective in mitigating the
potential for such risks. Generally, the risks of such conflicts of interest
are increased to the extent that a portfolio manager has a financial incentive
to favor one account over another. Pioneer has structured its compensation
arrangements in a manner that is intended to limit such potential for conflicts
of interest. See "Compensation of Portfolio Managers" below.

o A portfolio manager could favor one account over another in allocating new
  investment opportunities that have limited supply, such as initial public
  offerings and private placements. If, for example, an initial public
  offering that was expected to appreciate in value significantly shortly
  after the offering was allocated to a single account, that account may be
  expected to have better investment performance than other accounts that did
  not receive an allocation of the initial public offering. Generally,
  investments for which there is limited availability are allocated based upon
  a range of factors including available cash and consistency with the
  accounts' investment objectives and policies. This allocation methodology
  necessarily involves some subjective elements but is intended over time to
  treat each client in an equitable and fair manner. Generally, the investment
  opportunity is allocated among participating accounts on a pro rata basis.
  Although Pioneer believes that its practices are reasonably designed to
  treat each client in an equitable and fair manner, there may be instances
  where a fund may not participate, or may participate to a lesser degree than
  other clients, in the allocation of an investment opportunity.

o A portfolio manager could favor one account over another in the order in
  which trades for the accounts are placed. If a portfolio manager determines
  to purchase a security for more than one account in an aggregate amount that
  may influence the market price of the security, accounts that purchased or
  sold the security first may receive a more favorable price than accounts
  that made subsequent transactions. The less liquid the market for the
  security or the greater the percentage that the proposed aggregate


                                       58


 purchases or sales represent of average daily trading volume, the greater the
 potential for accounts that make subsequent purchases or sales to receive a
 less favorable price. When a portfolio manager intends to trade the same
 security on the same day for more than one account, the trades typically are
 "bunched," which means that the trades for the individual accounts are
 aggregated and each account receives the same price. There are some types of
 accounts as to which bunching may not be possible for contractual reasons
 (such as directed brokerage arrangements). Circumstances may also arise where
 the trader believes that bunching the orders may not result in the best
 possible price. Where those accounts or circumstances are involved, Pioneer
 will place the order in a manner intended to result in as favorable a price as
 possible for such client.

o A portfolio manager could favor an account if the portfolio manager's
  compensation is tied to the performance of that account to a greater degree
  than other accounts managed by the portfolio manager. If, for example, the
  portfolio manager receives a bonus based upon the performance of certain
  accounts relative to a benchmark while other accounts are disregarded for
  this purpose, the portfolio manager will have a financial incentive to seek
  to have the accounts that determine the portfolio manager's bonus achieve
  the best possible performance to the possible detriment of other accounts.
  Similarly, if Pioneer receives a performance-based advisory fee, the
  portfolio manager may favor that account, whether or not the performance of
  that account directly determines the portfolio manager's compensation.

o A portfolio manager could favor an account if the portfolio manager has a
  beneficial interest in the account, in order to benefit a large client or to
  compensate a client that had poor returns. For example, if the portfolio
  manager held an interest in an investment partnership that was one of the
  accounts managed by the portfolio manager, the portfolio manager would have
  an economic incentive to favor the account in which the portfolio manager
  held an interest.

o If the different accounts have materially and potentially conflicting
  investment objectives or strategies, a conflict of interest could arise. For
  example, if a portfolio manager purchases a security for one account and
  sells the same security for another account, such trading pattern may
  disadvantage either the account that is long or short. In making portfolio
  manager assignments, Pioneer seeks to avoid such potentially conflicting
  situations. However, where a portfolio manager is responsible for accounts
  with differing investment objectives and policies, it is possible that the
  portfolio manager will conclude that it is in the best interest of one
  account to sell a portfolio security while another account continues to hold
  or increase the holding in such security.


COMPENSATION OF PORTFOLIO MANAGERS
Pioneer has adopted a system of compensation for portfolio managers that seeks
to align the financial interests of the portfolio managers with those of
shareholders of the accounts (including Pioneer funds) the portfolio managers
manage, as well as with the financial performance of Pioneer. The compensation
program for all Pioneer portfolio managers includes a base salary (determined
by the rank and tenure of the employee) and an annual bonus program, as well as
customary benefits that are offered generally to all full-time employees. Base
compensation is fixed and normally reevaluated on an annual basis. Pioneer
seeks to set base compensation at market rates, taking into account the
experience and responsibilities of the portfolio manager. The bonus plan is
intended to provide a competitive level of annual bonus compensation that is
tied to the portfolio manager achieving superior investment performance and
align the interests of the investment professional with those of shareholders,
as well as with the financial performance of Pioneer. Any bonus under the plan
is completely discretionary, with a maximum annual bonus that may be in excess
of base salary. The annual bonus is based upon a combination of the following
factors:

o QUANTITATIVE INVESTMENT PERFORMANCE. The quantitative investment performance
  calculation is based on pre-tax investment performance of all of the
  accounts managed by the portfolio manager (which includes the fund and any
  other accounts managed by the portfolio manager) over a one-year period (20%
  weighting) and four-year period (80% weighting), measured for periods ending
  on December 31.


                                       59


 The accounts, which include the fund, are ranked against a group of mutual
 funds with similar investment objectives and investment focus (60%) and a
 broad-based securities market index measuring the performance of the same type
 of securities in which the accounts invest (40%), which, in the case of the
 fund, is the Barclays Capital Aggregate Bond Index. As a result of these two
 benchmarks, the performance of the portfolio manager for compensation purposes
 is measured against the criteria that are relevant to the portfolio manager's
 competitive universe.

o QUALITATIVE PERFORMANCE. The qualitative performance component with respect
  to all of the accounts managed by the portfolio manager includes objectives,
  such as effectiveness in the areas of teamwork, leadership, communications
  and marketing, that are mutually established and evaluated by each portfolio
  manager and management.

o PIONEER RESULTS AND BUSINESS LINE RESULTS. Pioneer's financial performance,
  as well as the investment performance of its investment management group,
  affect a portfolio manager's actual bonus by a leverage factor of plus or
  minus (+/-) a predetermined percentage.

The quantitative and qualitative performance components comprise 80% and 20%,
respectively, of the overall bonus calculation (on a pre-adjustment basis). A
portion of the annual bonus is deferred for a specified period and may be
invested in one or more Pioneer funds.

Certain portfolio managers participate in other programs designed to reward and
retain key contributors. Senior executives or other key employees are granted
performance units based on the stock price performance of UniCredit and the
financial performance of Pioneer Global Asset Management S.p.A., which are
affiliates of Pioneer. Portfolio managers also may participate in a deferred
compensation program, whereby deferred amounts are invested in one or more
Pioneer funds.

10. PORTFOLIO TRANSACTIONS

All orders for the purchase or sale of portfolio securities are placed on
behalf of the fund by Pioneer pursuant to authority contained in the fund's
management contract. Securities purchased and sold on behalf of the fund
normally will be traded in the over-the-counter market on a net basis (i.e.
without commission) through dealers acting for their own account and not as
brokers or otherwise through transactions directly with the issuer of the
instrument. The cost of securities purchased from underwriters includes an
underwriter's commission or concession, and the prices at which securities are
purchased and sold from and to dealers include a dealer's markup or markdown.
Pioneer normally seeks to deal directly with the primary market makers unless,
in its opinion, better prices are available elsewhere.


                                       60


Pioneer seeks to obtain overall best execution on portfolio trades. The price
of securities and any commission rate paid are always factors, but frequently
not the only factors, in judging best execution. In selecting brokers or
dealers, Pioneer considers various relevant factors, including, but not limited
to, the size and type of the transaction; the nature and character of the
markets for the security to be purchased or sold; the execution efficiency,
settlement capability and financial condition of the dealer; the dealer's
execution services rendered on a continuing basis; and the reasonableness of
any dealer spreads. Transactions in non-U.S. equity securities are executed by
broker-dealers in non-U.S. countries in which commission rates may not be
negotiable (as such rates are in the U.S.).

Pioneer may select broker-dealers that provide brokerage and/or research
services to the fund and/or other investment companies or other accounts
managed by Pioneer over which it or its affiliates exercise investment
discretion. In addition, consistent with Section 28(e) of the Securities
Exchange Act of 1934, as amended, if Pioneer determines in good faith that the
amount of commissions charged by a broker-dealer is reasonable in relation to
the value of the brokerage and research services provided by such broker, the
fund may pay commissions to such broker-dealer in an amount greater than the
amount another firm may charge. Such services may include advice concerning the
value of securities; the advisability of investing in, purchasing or selling
securities; the availability of securities or the purchasers or sellers of
securities; providing stock quotation services, credit rating service
information and comparative fund statistics; furnishing analyses, electronic
information services, manuals and reports concerning issuers, industries,
securities, economic factors and trends, portfolio strategy, and performance of
accounts and particular investment decisions; and effecting securities
transactions and performing functions incidental thereto (such as clearance and
settlement). Pioneer maintains a listing of broker-dealers who provide such
services on a regular basis. However, because many transactions on behalf of
the fund and other investment companies or accounts managed by Pioneer are
placed with broker-dealers (including broker-dealers on the listing) without
regard to the furnishing of such services, it is not possible to estimate the
proportion of such transactions directed to such dealers solely because such
services were provided. Pioneer believes that no exact dollar value can be
calculated for such services.

The research received from broker-dealers may be useful to Pioneer in rendering
investment management services to the fund as well as other investment
companies or other accounts managed by Pioneer, although not all such research
may be useful to the fund. Conversely, such information provided by brokers or
dealers who have executed transaction orders on behalf of such other accounts
may be useful to Pioneer in carrying out its obligations to the fund. The
receipt of such research enables Pioneer to avoid the additional expenses that
might otherwise be incurred if it were to attempt to develop comparable
information through its own staff.

The fund may participate in third-party brokerage and/or expense offset
arrangements to reduce the fund's total operating expenses. Pursuant to
third-party brokerage arrangements, the fund may incur lower expenses by
directing brokerage to third-party broker-dealers which have agreed to use part
of their commission to pay the fund's fees to service providers unaffiliated
with Pioneer or other expenses. Since the commissions paid to the third party
brokers reflect a commission cost that the fund would generally expect to incur
on its brokerage transactions but not necessarily the lowest possible
commission, this arrangement is intended to reduce the fund's operating
expenses without increasing the cost of its brokerage commissions. Since use of
such directed brokerage is subject to the requirement to achieve best execution
in connection with the fund's brokerage transactions, there can be no assurance
that such arrangements will be utilized. Pursuant to expense offset
arrangements, the fund may incur lower transfer agency expenses due to interest
earned on cash held with the transfer agent. See "Financial highlights" in the
prospectus.


                                       61


See the table in "Annual Fee, Expense and Other Information" for aggregate
brokerage and underwriting commissions paid by the fund in connection with its
portfolio transactions during recently completed fiscal years. The Board of
Trustees periodically reviews Pioneer's performance of its responsibilities in
connection with the placement of portfolio transactions on behalf of the fund.


11. DESCRIPTION OF SHARES

As an open-end management investment company, the fund continuously offers its
shares to the public and under normal conditions must redeem its shares upon
the demand of any shareholder at the next determined net asset value per share
less any applicable contingent deferred sales charge ("CDSC"). See "Sales
Charges." When issued and paid for in accordance with the terms of the
prospectus and statement of additional information, shares of the fund are
fully paid and non-assessable. Shares will remain on deposit with the fund's
transfer agent and certificates will not normally be issued.

The fund is a series of Pioneer Bond Fund, a Delaware statutory trust. The
Trustees have authorized the issuance of the following classes of shares of the
fund, designated as Class A, Class C, Class K, Class R and Class Y shares. Each
share of a class of the fund represents an equal proportionate interest in the
assets of the fund allocable to that class. Upon liquidation of the fund,
shareholders of each class of the fund are entitled to share pro rata in the
fund's net assets allocable to such class available for distribution to
shareholders. The Trust reserves the right to create and issue additional
series or classes of shares, in which case the shares of each class of a series
would participate equally in the earnings, dividends and assets allocable to
that class of the particular series.

The shares of each class represent an interest in the same portfolio of
investments of the fund. Each class has identical rights (based on relative net
asset values) to assets and liquidation proceeds. Share classes can bear
different 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 by each class. Share classes have exclusive voting rights
with respect to matters affecting only that class, including with respect to
the distribution plan for that class.


THE TRUST
The Trust's operations are governed by the Amended and Restated Agreement and
Declaration of Trust, dated as of July 1, 2008 (referred to in this section as
the declaration). A copy of the Trust's Certificate of Trust dated as of
January 5, 1999, as amended, is on file with the office of the Secretary of
State of Delaware.

Delaware law provides a statutory framework for the powers, duties, rights and
obligations of the board (referred to in this section as the trustees) and
shareholders of the Delaware statutory trust, while the more specific powers,
duties, rights and obligations of the trustees and the shareholders are
determined by the trustees as set forth in the declaration. Some of the more
significant provisions of the declaration are described below.


SHAREHOLDER VOTING
The declaration provides for shareholder voting as required by the 1940 Act or
other applicable laws but otherwise permits, consistent with Delaware law,
actions by the trustees without seeking the consent of shareholders. The
trustees may, without shareholder approval, where approval of shareholders is
not otherwise required under the 1940 Act, merge or consolidate the Trust into
other entities, reorganize the Trust or any series or class into another trust
or entity or a series or class of another entity, sell the assets of the Trust
or any series or class to another entity, or a series or class of another
entity, or terminate the Trust or any series or class.


                                       62


The fund is not required to hold an annual meeting of shareholders, but the
fund will call special meetings of shareholders whenever required by the 1940
Act or by the terms of the declaration. The declaration gives the board the
flexibility to specify either per share voting or dollar-weighted voting. Under
per share voting, each share 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 the shareholder owns, but by the dollar value of those shares
determined on the record date. All shareholders of all series and classes of
the Trust vote together, except where required by the 1940 Act to vote
separately by series or by class, or when the trustees have determined that a
matter affects only the interests of one or more series or classes of shares.


ELECTION AND REMOVAL OF TRUSTEES
The declaration provides that the trustees may establish the number of trustees
and that vacancies on the board may be filled by the remaining trustees, except
when election of trustees by the shareholders is required under the 1940 Act.
Trustees are then elected by a plurality of votes cast by shareholders at a
meeting at which a quorum is present. The declaration also provides that a
mandatory retirement age may be set by action of two-thirds of the trustees and
that trustees may be removed at any time or for any reason by a majority of the
board or by a majority of the outstanding shareholders of the Trust.


AMENDMENTS TO THE DECLARATION
The trustees are authorized to amend the declaration without the vote of
shareholders, but no amendment may be made that impairs the exemption from
personal liability granted in the declaration to persons who are or have been
shareholders, trustees, officers or, employees of the trust or that limit the
rights to indemnification or insurance provided in the declaration with respect
to actions or omissions of persons entitled to indemnification under the
declaration prior to the amendment.


ISSUANCE AND REDEMPTION OF SHARES
The fund may issue an unlimited number of shares for such consideration and on
such terms as the trustees may determine. Shareholders are not entitled to any
appraisal, preemptive, conversion, exchange or similar rights, except as the
trustees may determine. The fund may involuntarily redeem a shareholder's
shares upon certain conditions as may be determined by the trustees, including,
for example, if the shareholder fails to provide the fund with identification
required by law, or if the fund is unable to verify the information received
from the shareholder. Additionally, as discussed below, shares may be redeemed
in connection with the closing of small accounts.


DISCLOSURE OF SHAREHOLDER HOLDINGS
The declaration specifically requires shareholders, upon demand, to disclose to
the fund information with respect to the direct and indirect ownership of
shares in order to comply with various laws or regulations, and the fund may
disclose such ownership if required by law or regulation.


SMALL ACCOUNTS
The declaration provides that the fund may close out a shareholder's account by
redeeming all of the shares in the account if the account falls below a minimum
account size (which may vary by class) that may be set by the trustees from
time to time. Alternately, the declaration permits the fund to assess a fee for
small accounts (which may vary by class) and redeem shares in the account to
cover such fees, or convert the shares into another share class that is geared
to smaller accounts.


SERIES AND CLASSES
The declaration provides that the trustees may establish series and classes in
addition to those currently established and to determine the rights and
preferences, limitations and restrictions, including qualifications for
ownership, conversion and exchange features, minimum purchase and account size,
expenses


                                       63


and charges, and other features of the series and classes. The trustees may
change any of those features, terminate any series or class, combine series
with other series in the trust, combine one or more classes of a series with
another class in that series or convert the shares of one class into another
class.

Each share of the fund, as a series of the Trust, represents an interest in the
fund only and not in the assets of any other series of the Trust.


SHAREHOLDER, TRUSTEE AND OFFICER LIABILITY
The declaration provides that shareholders are not personally liable for the
obligations of the fund and requires a fund to indemnify a shareholder against
liability arising solely from the shareholder's ownership of shares in the
fund. In addition, the fund will assume the defense of any claim against a
shareholder for personal liability at the request of the shareholder. The
declaration further provides that no trustee, officer or employee of the fund
shall be liable to the fund or any shareholder for any action, failure to act,
error or mistake except in cases of bad faith, willful misfeasance, gross
negligence or reckless disregard of duty. The declaration requires the fund to
indemnify each trustee, director, officer, employee and authorized agent to the
fullest extent permitted by law against liability and against all expenses
reasonably incurred or paid by him in connection with any claim, action, suit
or proceeding in which he becomes involved as a party or otherwise by virtue of
his being or having been such a trustee, director, officer, employee, or agent
and against amounts paid or incurred by him in settlement thereof. The 1940 Act
currently provides that no officer or director shall be protected from
liability to the fund or shareholders for willful misfeasance, bad faith, gross
negligence, or reckless disregard of the duties of office. The declaration
extends to trustees, officers and employees of the fund the full protection
from liability that the law allows.

The declaration provides that the appointment, designation or identification of
a trustee as chairperson, a member of a committee, an expert, lead independent
trustee, or any other special appointment, designation or identification shall
not impose any heightened standard of care or liability on such trustee.


DERIVATIVE ACTIONS
The declaration provides a detailed process for the bringing of derivative
actions by shareholders in order to permit legitimate inquiries and claims
while avoiding the time, expense, distraction, and other harm that can be
caused to the fund or its shareholders as a result of spurious shareholder
demands and derivative actions. Prior to bringing a derivative action, a demand
by three unrelated shareholders must first be made on the fund's trustees. The
declaration details various information, certifications, undertakings and
acknowledgements that must be included in the demand. Following receipt of the
demand, the trustees have a period of 90 days, which may be extended by an
additional 60 days, to consider the demand. If a majority of the trustees who
are considered independent for the purposes of considering the demand determine
that maintaining the suit would not be in the best interests of the fund, the
trustees are required to reject the demand and the complaining shareholders may
not proceed with the derivative action unless the shareholders are able to
sustain the burden of proof to a court that the decision of the trustees not to
pursue the requested action was not a good faith exercise of their business
judgment on behalf of the fund. The declaration further provides that
shareholders owning shares representing at least 10% of the voting power of the
affected fund must join in bringing the derivative action. If a demand is
rejected, the complaining shareholders will be responsible for the costs and
expenses (including attorneys' fees) incurred by the fund in connection with
the consideration of the demand, if in the judgment of the independent
trustees, the demand was made without reasonable cause or for an improper
purpose. If a derivative action is brought in violation of the declaration, the
shareholders bringing the action may be responsible for the fund's costs,
including attorneys' fees.


                                       64


The declaration further provides that the fund shall be responsible for payment
of attorneys' fees and legal expenses incurred by a complaining shareholder
only if required by law, and any attorneys' fees that the fund is obligated to
pay shall be calculated using reasonable hourly rates. The declaration also
requires that actions by shareholders against the fund be brought only in
federal court in Boston, Massachusetts, or if not permitted to be brought in
federal court, then in state court in Boston, Massachusetts, and that
shareholders have no right to jury trial for such actions.


12. SALES CHARGES

The fund continuously offers the following classes of shares: Class A, Class C,
Class K, Class R and Class Y shares, as described in the prospectus. The fund
offers its shares at a reduced sales charge to investors who meet certain
criteria that permit the fund's shares to be sold with low distribution costs.
These criteria are described below or in the prospectus.


CLASS A SHARE SALES CHARGES
You may buy Class A shares at the public offering price, including a sales
charge, as follows:




                                           SALES CHARGE AS A % OF
                                   --------------------------------------
                                     OFFERING    NET AMOUNT        DEALER
AMOUNT OF PURCHASE                      PRICE      INVESTED   REALLOWANCE
---------------------------------  ----------  ------------  ------------
                                                    
Less than $100,000                     4.50          4.71           4.00
---------------------------------      ----          ----           ----
$100,000 but less than $250,000        3.50          3.63           3.00
---------------------------------      ----          ----           ----
$250,000 but less than $500,000        2.50          2.56           2.00
---------------------------------      ----          ----           ----
$500,000 or more                       0.00          0.00      see below
---------------------------------      ----          ----    ------------


The schedule of sales charges above is applicable to purchases of Class A
shares of the fund by (i) an individual, (ii) an individual and his or her
spouse and children under the age of 21 and (iii) a trustee or other fiduciary
of a trust estate or fiduciary account or related trusts or accounts including
pension, profit-sharing and other employee benefit trusts qualified under
Sections 401 or 408 of the Code although more than one beneficiary is involved;
however, pension, profit-sharing and other employee benefit trusts qualified
under Sections 401 or 408 of the Code which are eligible to purchase Class R
shares may aggregate purchases by beneficiaries of such plans only if the
pension, profit-sharing or other employee benefit trust has determined that it
does not require the services provided under the Class R Service Plan. The
sales charges applicable to a current purchase of Class A shares of the fund by
a person listed above is determined by adding the value of shares to be
purchased to the aggregate value (at the then current offering price) of shares
of any of the other Pioneer mutual funds previously purchased and then owned,
provided PFD is notified by such person or his or her broker-dealer each time a
purchase is made which would qualify. Pioneer mutual funds include all mutual
funds for which PFD serves as principal underwriter. At the sole discretion of
PFD, holdings of funds domiciled outside the U.S., but which are managed by
affiliates of Pioneer, may be included for this purpose.

No sales charge is payable at the time of purchase on investments of $500,000
or more, or for purchases by participants in employer-sponsored retirement
plans described below subject to a CDSC of 1% which may be imposed in the event
of a redemption of Class A shares within 12 months of purchase. PFD may, in its
discretion, pay a commission to broker-dealers who initiate and are responsible
for such purchases as follows:


      
1.00%    Up to $4 million
----     ---------------------------------
         Greater than $4 million and less
0.50%    than or equal to $50 million
----     ---------------------------------
0.25%    Over $50 million
----     ---------------------------------


                                       65


Commissions are based on cumulative investments in Class A shares of the
Pioneer funds. These commissions shall not be payable if the purchaser is
affiliated with the broker-dealer or if the purchase represents the
reinvestment of a redemption made during the previous 12 calendar months.
Broker-dealers who receive a commission in connection with Class A share
purchases at net asset value by employer-sponsored retirement plans with at
least $500,000 in total plan assets (or that has 1,000 or more eligible
participants for employer-sponsored retirement plans with accounts established
with Pioneer on or before March 31, 2004) will be required to return any
commissions paid or a pro rata portion thereof if the retirement plan redeems
its shares within 12 months of purchase.

If an investor eligible to purchase Class R shares is otherwise qualified to
purchase Class A shares at net asset value or at a reduced sales charge, Class
A shares may be selected where the investor does not require the distribution
and account services needs typically required by Class R share investors and/or
the broker-dealer has elected to forgo the level of compensation that Class R
shares provides.


LETTER OF INTENT ("LOI")
Reduced sales charges are available for purchases of $100,000 or more of Class
A shares (excluding any reinvestments of dividends and capital gain
distributions) made within a 13-month period pursuant to an LOI which may be
established by completing the Letter of Intent section of the Account
Application. The reduced sales charge will be the charge that would be
applicable to the purchase of the specified amount of Class A shares as if the
shares had all been purchased at the same time. A purchase not made pursuant to
an LOI may be included if the LOI is submitted to the fund's transfer agent
within 90 days of such purchase. You may also obtain the reduced sales charge
by including the value (at current offering price) of all your Class A shares
in the fund and all other Pioneer mutual funds held of record as of the date of
your LOI in the amount used to determine the applicable sales charge for the
Class A shares to be purchased under the LOI. Five percent of your total
intended purchase amount will be held in escrow by the fund's transfer agent,
registered in your name, until the terms of the LOI are fulfilled. When you
sign the Account Application, you agree to irrevocably appoint the fund's
transfer agent your attorney-in-fact to surrender for redemption any or all
shares held in escrow with full power of substitution. An LOI is not a binding
obligation upon the investor to purchase, or the fund to sell, the amount
specified in the LOI. Any share class for which no sales charge is paid cannot
be included under the LOI.

If the total purchases exceed the amount specified under the LOI and are in an
amount that would qualify for a further quantity discount, all transactions
will be recomputed on the expiration date of the LOI to effect the lower sales
charge. Any difference in the sales charge resulting from such recomputation
will be either delivered to you in cash or invested in additional shares at the
lower sales charge. The dealer, by signing the Account Application, agrees to
return to PFD, as part of such retroactive adjustment, the excess of the
commission previously reallowed or paid to the dealer over that which is
applicable to the actual amount of the total purchases under the LOI.

If the total purchases are less than the amount specified under the LOI, you
must remit to PFD any difference between the sales charge on the amount
actually purchased and the amount originally specified in the LOI. When the
difference is paid, the shares held in escrow will be deposited to your
account. If you do not pay the difference in sales charge within 20 days after
written request from PFD or your dealer, the fund's transfer agent, after
receiving instructions from PFD, will redeem the appropriate number of shares
held in escrow to realize the difference and release any excess.

If sufficient shares are not purchased to complete the LOI because all
registered account owners died within the 13-month period, PFD will consider
the LOI complete and will not adjust past transactions for purposes of the
sales charges paid. Commissions to dealers will not be adjusted or paid on the
difference between the LOI amount and the amount actually invested before the
shareholders' deaths.


                                       66


CLASS C SHARES
You may buy Class C shares at the net asset value per share next computed after
receipt of a purchase order without the imposition of an initial sales charge;
however, Class C shares redeemed within one year of purchase will be subject to
a CDSC of 1%. The charge will be assessed on the amount equal to the lesser of
the current market value or the original purchase cost of the shares being
redeemed. No CDSC will be imposed on increases in account value above the
initial purchase price, including shares derived from the reinvestment of
dividends or capital gain distributions. Class C shares do not convert to any
other class of fund shares.

In processing redemptions of Class C shares, the fund will first redeem shares
not subject to any CDSC and then shares held for the longest period of time
during the one-year period. As a result, you will pay the lowest possible CDSC.

Proceeds from the CDSC are paid to PFD and are used in whole or in part to
defray PFD's expenses related to providing distribution-related services to the
fund in connection with the sale of Class C shares, including the payment of
compensation to broker-dealers.


CLASS K SHARES
No front-end, deferred or asset-based sales charges are applicable to Class K
shares.


CLASS R SHARES
You may buy Class R shares at the net asset value per share next computed after
receipt of a purchase order without the imposition of an initial sales charge
or CDSC.

Class R shares are available to certain tax-deferred retirement plans
(including 401(k) plans, employer-sponsored 403(b) plans, 457 plans, profit
sharing and money purchase pension plans, defined benefit plans and
non-qualified deferred compensation plans) held in plan level or omnibus
accounts. Class R shares also are available to individual retirement account
rollovers from eligible retirement plans that offered one or more Pioneer funds
as investment options. Class R shares generally are not available to
non-retirement accounts, traditional and Roth IRA's, Coverdell Education
Savings Accounts, SEP's, SAR-SEP's, Simple IRA's, individual 403(b)'s or
retirement plans that are not subject to the Employee Retirement Income
Security Act of 1974.

Investors that are eligible to purchase Class R shares may also be eligible to
purchase other share classes. Your investment professional can help you
determine which class is appropriate. You should ask your investment
professional if you qualify for a waiver of sales charges on another class and
take that into consideration when selecting a class of shares. Your investment
firm may receive different compensation depending upon which class is chosen.


CLASS Y SHARES
No front-end, deferred or asset-based sales charges are applicable to Class Y
shares.


ADDITIONAL PAYMENTS TO FINANCIAL INTERMEDIARIES
The financial intermediaries through which shares are purchased may receive all
or a portion of the sales charges and Rule 12b-1 fees discussed above. In
addition to those payments, Pioneer or one or more of its affiliates
(collectively, "Pioneer Affiliates") may make additional payments to financial
intermediaries in connection with the promotion and sale of shares of Pioneer
funds. Pioneer Affiliates make these payments from their own resources, which
include resources that derive from compensation for providing services to the
Pioneer funds. These additional payments are described below. The categories
described below are not mutually exclusive. The same financial intermediary may
receive payments under more than one or all categories. Many financial
intermediaries that sell shares of Pioneer funds receive one or more types of
these payments. The financial intermediary typically initiates requests for
additional


                                       67


compensation. Pioneer negotiates these arrangements individually with financial
intermediaries and the amount of payments and the specific arrangements may
differ significantly. A financial intermediary also may receive different
levels of compensation with respect to sales or assets attributable to
different types of clients of the same intermediary or different Pioneer funds.
Where services are provided, the costs of providing the services and the
overall array of services provided may vary from one financial intermediary to
another. Pioneer Affiliates do not make an independent assessment of the cost
of providing such services. While the financial intermediaries may request
additional compensation from Pioneer to offset costs incurred by the financial
intermediary in servicing its clients, the financial intermediary may earn a
profit on these payments, since the amount of the payment may exceed the
financial intermediary's costs. In this context, "financial intermediary"
includes any broker, dealer, bank (including bank trust departments), insurance
company, transfer agent, registered investment adviser, financial planner,
retirement plan administrator and any other financial intermediary having a
selling, administrative and shareholder servicing or similar agreement with a
Pioneer Affiliate.

A financial intermediary's receipt of additional compensation may create
conflicts of interest between the financial intermediary and its clients. Each
type of payment discussed below may provide your financial intermediary with an
economic incentive to actively promote the Pioneer funds over other mutual
funds or cooperate with the distributor's promotional efforts. The receipt of
additional compensation for Pioneer Affiliates may be an important
consideration in a financial intermediary's willingness to support the sale of
the Pioneer funds through the financial intermediary's distribution system.
Pioneer Affiliates are motivated to make the payments described above since
they promote the sale of Pioneer fund shares and the retention of those
investments by clients of financial intermediaries. In certain cases these
payments could be significant to the financial intermediary. The financial
intermediary may charge additional fees or commissions other than those
disclosed in the prospectus. Financial intermediaries may categorize and
disclose these arrangements differently than Pioneer Affiliates do. To the
extent financial intermediaries sell more shares of the funds or retain shares
of the funds in their clients' accounts, Pioneer Affiliates benefit from the
incremental management and other fees paid to Pioneer Affiliates by the funds
with respect to those assets.


REVENUE SHARING PAYMENTS
Pioneer Affiliates make revenue sharing payments as incentives to certain
financial intermediaries to promote and sell shares of Pioneer funds. The
benefits Pioneer Affiliates receive when they make these payments include,
among other things, entry into or increased visibility in the financial
intermediary's sales system, participation by the intermediary in the
distributor's marketing efforts (such as helping facilitate or providing
financial assistance for conferences, seminars or other programs at which
Pioneer personnel may make presentations on the funds to the intermediary's
sales force), placement on the financial intermediary's preferred fund list,
and access (in some cases, on a preferential basis over other competitors) to
individual members of the financial intermediary's sales force or management.
Revenue sharing payments are sometimes referred to as "shelf space" payments
because the payments compensate the financial intermediary for including
Pioneer funds in its fund sales system (on its "shelf space"). Pioneer
Affiliates also may pay financial intermediaries "finders'" or "referral" fees
for directing investors to the Pioneer funds. Pioneer Affiliates compensate
financial intermediaries differently depending typically on the level and/or
type of considerations provided by the financial intermediary.

The revenue sharing payments Pioneer Affiliates make may be calculated on sales
of shares of Pioneer funds ("Sales-Based Payments"); although there is no
policy limiting the amount of Sales-Based Payments any one financial
intermediary may receive, the total amount of such payments normally does not
exceed 0.25% per annum of those assets. Such payments also may be calculated on
the average daily net assets of the applicable Pioneer funds attributable to
that particular financial intermediary ("Asset-Based Payments"); although there
is no policy limiting the amount of Asset-Based Payments any one financial
intermediary may receive, the total amount of such payments normally does not
exceed 0.16% per annum of those assets. Sales-Based Payments primarily create
incentives to make new sales of shares of


                                       68


Pioneer funds and Asset-Based Payments primarily create incentives to retain
previously sold shares of Pioneer funds in investor accounts. Pioneer
Affiliates may pay a financial intermediary either or both Sales-Based Payments
and Asset-Based Payments.


ADMINISTRATIVE AND PROCESSING SUPPORT PAYMENTS
Pioneer Affiliates also may make payments to certain financial intermediaries
that sell Pioneer fund shares for certain administrative services, including
record keeping and sub-accounting shareholder accounts, to the extent that the
funds do not pay for these costs directly. Pioneer Affiliates also may make
payments to certain financial intermediaries that sell Pioneer fund shares in
connection with client account maintenance support, statement preparation and
transaction processing. The types of payments that Pioneer Affiliates may make
under this category include, among others, payment of ticket charges per
purchase or exchange order placed by a financial intermediary, payment of
networking fees in connection with certain mutual fund trading systems, or
one-time payments for ancillary services such as setting up funds on a
financial intermediary's mutual fund trading system.


OTHER PAYMENTS
From time to time, Pioneer Affiliates, at their expense, may provide additional
compensation to financial intermediaries which sell or arrange for the sale of
shares of the Pioneer funds. Such compensation provided by Pioneer Affiliates
may include financial assistance to financial intermediaries that enable
Pioneer Affiliates to participate in and/or present at conferences or seminars,
sales or training programs for invited registered representatives and other
employees, client entertainment, client and investor events, and other
financial intermediary-sponsored events, and travel expenses, including lodging
incurred by registered representatives and other employees in connection with
client prospecting, retention and due diligence trips. Other compensation may
be offered to the extent not prohibited by federal or state laws or any
self-regulatory agency, such as FINRA. Pioneer Affiliates make payments for
entertainment events they deem appropriate, subject to Pioneer Affiliates'
guidelines and applicable law. These payments may vary depending upon the
nature of the event or the relationship.

As of January 1, 2015, Pioneer anticipates that the following broker-dealers or
their affiliates will receive additional payments as described in the fund's
prospectus and statement of additional information:

13. REDEEMING SHARES

Redemptions may be suspended or payment postponed during any period in which
any of the following conditions exist: the New York Stock Exchange (the
"Exchange") is closed or trading on the Exchange is restricted; an emergency
exists as a result of which disposal by the fund of securities owned by it is
not reasonably practicable or it is not reasonably practicable for the fund to
fairly determine the value of the net assets of its portfolio; or otherwise as
permitted by the rules of or by the order of the SEC.


                                       70


Redemptions and repurchases are taxable transactions for shareholders that are
subject to U.S. federal income tax. The net asset value per share received upon
redemption or repurchase may be more or less than the cost of shares to an
investor, depending on the market value of the portfolio at the time of
redemption or repurchase..


SYSTEMATIC WITHDRAWAL PLAN(S) ("SWP") (CLASS A, CLASS C AND CLASS R SHARES)
A SWP is designed to provide a convenient method of receiving fixed payments at
regular intervals from fund share accounts having a total value of not less
than $10,000. You must also be reinvesting all dividends and capital gain
distributions to use the SWP option.

Periodic payments will be deposited monthly, quarterly, semiannually or
annually directly into a bank account designated by the applicant or will be
sent by check to the applicant, or any person designated by the applicant.
Payments can be made either by check or electronic funds transfer to a bank
account designated by you. Withdrawals from Class C and Class R share accounts
are limited to 10% of the value of the account at the time the SWP is
established. See "Qualifying for a reduced sales charge" in the prospectus. If
you direct that withdrawal payments be paid to another person, want to change
the bank where payments are sent or designate an address that is different from
the account's address of record after you have opened your account, a medallion
signature guarantee must accompany your instructions. Withdrawals under the SWP
are redemptions that may have tax consequences for you.

While you are making systematic withdrawals from your account, you may pay
unnecessary initial sales charges on additional purchases of Class A shares or
contingent deferred sales charges. SWP redemptions reduce and may ultimately
exhaust the number of shares in your account. In addition, the amounts received
by a shareholder cannot be considered as yield or income on his or her
investment because part of such payments may be a return of his or her
investment.

A SWP may be terminated at any time (1) by written notice to the fund or from
the fund to the shareholder; (2) upon receipt by the fund of appropriate
evidence of the shareholder's death; or (3) when all shares in the
shareholder's account have been redeemed.

You may obtain additional information by calling the fund at 1-800-225-6292.


REINSTATEMENT PRIVILEGE (CLASS A SHARES)
Subject to the provisions outlined in the prospectus, you may reinvest all or
part of your sale proceeds from Class A shares without a sales charge into
Class A shares of a Pioneer mutual fund. However, the distributor will not pay
your investment firm a commission on any reinvested amount.


14. TELEPHONE AND ONLINE TRANSACTIONS

You may purchase, exchange or sell shares by telephone or online. Class K,
Class R and Class Y shares may not be purchased by telephone, and Class K,
Class R and Class Y shareowners are not eligible for online transaction
privileges. See the prospectus for more information. For personal assistance,
call 1-800-225-6292 between 8:00 a.m. and 7:00 p.m. Eastern time on weekdays.
Computer-assisted telephone transactions may be available to shareholders who
have prerecorded certain bank information (see "FactFone/SM/"). YOU ARE
STRONGLY URGED TO CONSULT WITH YOUR INVESTMENT PROFESSIONAL PRIOR TO REQUESTING
ANY TELEPHONE OR ONLINE TRANSACTION.


TELEPHONE TRANSACTION PRIVILEGES
To confirm that each transaction instruction received by telephone is genuine,
the fund will record each telephone transaction, require the caller to provide
validating information for the account and send you a written confirmation of
each telephone transaction. Different procedures may apply to accounts that are
registered to non-U.S. citizens or that are held in the name of an institution
or in the name of an investment broker-dealer or other third party. If
reasonable procedures, such as those described above,


                                       71


are not followed, the fund may be liable for any loss due to unauthorized or
fraudulent instructions. The fund may implement other procedures from time to
time. In all other cases, neither the fund, the fund's transfer agent nor PFD
will be responsible for the authenticity of instructions received by telephone;
therefore, you bear the risk of loss for unauthorized or fraudulent telephone
transactions.


ONLINE TRANSACTION PRIVILEGES
If your account is registered in your name, you may be able buy, exchange or
sell fund shares online. Your investment firm may also be able to buy, exchange
or sell your fund shares online.

To establish online transaction privileges:

o For new accounts, complete the online section of the account application

o For existing accounts, complete an account options form, write to the fund or
  complete the online authorization screen on us.pioneerinvestments.com

To use online transactions, you must read and agree to the terms of an online
transaction agreement available on the Pioneer website. When you or your
investment firm requests an online transaction the transfer agent
electronically records the transaction, requires an authorizing password and
sends a written confirmation. The fund may implement other procedures from time
to time. Different procedures may apply if you have a non-U.S. account or if
your account is registered in the name of an institution, broker-dealer or
other third party. You may not be able to use the online transaction privilege
for certain types of accounts, including most retirement accounts.


TELEPHONE AND WEBSITE ONLINE ACCESS
You may have difficulty contacting the fund by telephone or accessing
us.pioneerinvestments.com during times of market volatility or disruption in
telephone or Internet services. On Exchange holidays or on days when the
Exchange closes early, Pioneer will adjust the hours for the telephone center
and for online transaction processing accordingly. If you are unable to access
us.pioneerinvestments.com or to reach the fund by telephone, you should
communicate with the fund in writing.


FACTFONE/SM/
FactFone/SM/ is an automated inquiry and telephone transaction system available

                                       72


All performance numbers communicated through FactFone/SM/ represent past
performance, and figures include the maximum applicable sales charge. A
shareholder's actual yield and total return will vary with changing market
conditions. The value of each class of shares (except for Pioneer Cash Reserves
Fund, which seeks to maintain a stable $1.00 share price) will also vary, and
such shares may be worth more or less at redemption than their original cost.


15. PRICING OF SHARES

The net asset value per share of each class of the fund is determined as of the
scheduled close of regular trading on the Exchange (normally 4:00 p.m. Eastern
time) on each day on which the Exchange is open for trading. As of the date of
this statement of additional information, the Exchange is open for trading
every weekday except for the days the following holidays are observed: New
Year's Day, Martin Luther King, Jr. Day, Presidents' Day, Good Friday, Memorial
Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day. The net
asset value per share of each class of the fund is also determined on any other
day on which the level of trading in its portfolio securities is sufficiently
high that the current net asset value per share might be materially affected by
changes in the value of its portfolio securities. The fund is not required to
determine its net asset value per share on any day on which no purchase orders
in good order for fund shares are received and no shares are tendered and
accepted for redemption.

Ordinarily, investments in debt securities are valued on the basis of
information furnished by a pricing service which utilizes primarily a matrix
system (which reflects such factors as security prices, yields, maturities and
ratings), supplemented by dealer and exchange quotations. Other securities are
valued at the last sale price on the principal exchange or market where they
are traded. Securities which have not traded on the date of valuation or
securities for which sales prices are not generally reported are valued at the
mean between the current bid and asked prices.

Securities quoted in foreign currencies are converted to U.S. dollars utilizing
foreign exchange rates employed by the fund's independent pricing services.
Generally, trading in non U.S. securities is substantially completed each day
at various times prior to the close of regular trading on the Exchange. The
values of such securities used in computing the net asset value of the fund's
shares are determined as of such times. Foreign currency exchange rates are
also generally determined prior to the close of regular trading on the
Exchange. Occasionally, events which affect the values of such securities and
such exchange rates may occur between the times at which they are determined
and the close of regular trading on the Exchange and will therefore not be
reflected in the computation of the fund's net asset value. International
securities markets may be open on days when the U.S. markets are closed. For
this reason, the value of any international securities owned by the fund could
change on a day you cannot buy or sell shares of the fund.

When prices determined using the foregoing methods are not available or are
considered by Pioneer to be unreliable, the fund uses fair value methods to
value its securities in accordance with procedures approved by the fund's
trustees. The fund also may use fair value pricing methods to value its
securities, including a non-U.S. security, when Pioneer determines that prices
determined using the foregoing methods no longer accurately reflect the value
of the security due to factors affecting one or more relevant securities
markets or the specific issuer. Valuing securities using fair value methods may
cause the net asset value of the fund's shares to differ from the net asset
value that would be calculated using closing market prices. In connection with
making fair value determinations of the value of fixed income securities, the
fund may use a pricing matrix. The prices used for these securities may differ
from the amounts received by the fund upon sale of the securities, and these
differences may be substantial.

The net asset value per share of each class of the fund is computed by taking
the value of all of the fund's assets attributable to a class, less the fund's
liabilities attributable to that class, and dividing the result by the number
of outstanding shares of that class. For purposes of determining net asset
value, expenses of the classes of the fund are accrued daily and taken into
account. The fund's maximum offering price


                                       73


per Class A share is determined by adding the maximum sales charge to the net
asset value per Class A share. Class C, Class K, Class R, and Class Y shares
are offered at net asset value without the imposition of an initial sales
charge (Class C may be subject to a CDSC).


16. TAX STATUS

The fund has elected to be treated, and has qualified and intends to continue
to qualify each year, as a "regulated investment company" under Subchapter M of
the Code, so that it will not pay U.S. federal income tax on income and capital
gains distributed to shareholders. In order to qualify as a regulated
investment company under Subchapter M of the Code, the fund must, among other
things, (i) derive at least 90% of its gross income for each taxable year from
dividends, interest, payments with respect to certain securities loans, gains
from the sale or other disposition of stock, securities or foreign currencies,
or other income (including gains from options, futures and forward contracts)
derived with respect to its business of investing in such stock, securities or
currencies, and net income derived from an interest in a qualified publicly
traded partnership (as defined in Section 851(h) of the Code) (the "90% income
test") and (ii) diversify its holdings so that, at the end of each quarter of
each taxable year: (a) at least 50% of the value of the fund's total assets is
represented by (1) cash and cash items, U.S. government securities, securities
of other regulated investment companies, and (2) other securities, with such
other securities limited, in respect of any one issuer, to an amount not
greater than 5% of the value of the fund's total assets and to not more than
10% of the outstanding voting securities of such issuer and (b) not more than
25% of the value of the fund's total assets is invested in (1) the securities
(other than U.S. government securities and securities of other regulated
investment companies) of any one issuer, (2) the securities (other than
securities of other regulated investment companies) of two or more issuers that
the fund controls and that are engaged in the same, similar, or related trades
or businesses, or (3) the securities of one or more qualified publicly traded
partnerships.

For purposes of the 90% income test, the character of income earned by certain
entities in which the fund invests that are not treated as corporations for
U.S. federal income tax purposes (e.g., partnerships other than certain
publicly traded partnerships or trusts that have not elected to be classified
as corporations under the "check-the-box" regulations) will generally pass
through to the fund. Consequently, in order to qualify as a regulated
investment company, the fund may be required to limit its equity investments in
such entities that earn fee income, rental income or other nonqualifying
income.

If the fund qualifies as a regulated investment company and properly
distributes to its shareholders each taxable year an amount equal to or
exceeding the sum of (i) 90% of its "investment company taxable income" as that
term is defined in the Code (which includes, among other things, dividends,
taxable interest, and the excess of any net short-term capital gains over net
long-term capital losses, as reduced by certain deductible expenses) without
regard to the deduction for dividends paid and (ii) 90% of the excess of its
gross tax-exempt interest income, if any, over certain disallowed deductions,
the fund generally will not be subject to U.S. federal income tax on any income
of the fund, including "net capital gain" (the excess of net long-term capital
gain over net short-term capital loss), distributed to shareholders. However,
if the fund meets such distribution requirements, but chooses to retain some
portion of its taxable income or gains, it generally will be subject to U.S.
federal income tax at regular corporate rates on the amount retained. The fund
may designate certain amounts retained as undistributed net capital gain in a
notice to its shareholders, who (i) will be required to include in income for
U.S. federal income tax purposes, as long-term capital gain, their
proportionate shares of the undistributed amount so designated, (ii) will be
entitled to credit their proportionate shares of the income tax paid by the
fund on that undistributed amount against their federal income tax liabilities
and to claim refunds to the extent such credits exceed their liabilities and
(iii) will be entitled to increase their tax basis, for federal income tax
purposes, in their shares by an amount equal to the excess of the amount of


                                       74


undistributed net capital gain included in their respective income over their
respective income tax credits. The fund intends to distribute at least annually
all or substantially all of its investment company taxable income (computed
without regard to the dividends-paid deduction), net tax-exempt interest
income, and net capital gain.

If, for any taxable year, the fund does not qualify as a regulated investment
company or does not satisfy the 90% distribution requirement, it will be
treated as a U.S. corporation subject to U.S. federal income tax, thereby
subjecting any income earned by the fund to tax at the corporate level and to a
further tax at the shareholder level when such income is distributed. Under
certain circumstances, the fund may be able to cure a failure to qualify as a
regulated investment company, but in order to do so, the fund may incur
significant fund-level taxes and may be forced to dispose of certain assets.

Under the Code, the fund will be subject to a nondeductible 4% U.S. federal
excise tax on a portion of its undistributed ordinary income and capital gain
net income if it fails to meet certain distribution requirements with respect
to each calendar year and year ending October 31, respectively. The fund
intends to make distributions in a timely manner and accordingly does not
expect to be subject to the excise tax.

The fund declares a dividend from any net investment income (other than capital
gains) each business day. The fund generally pays dividends from any net
investment income (other than capital gains) on the last business day of the
month or shortly thereafter. The fund distributes any net short- and long-term
capital gains in November. Dividends from income and/or capital gains may also
be paid at such other times as may be necessary for the fund to avoid U.S.
federal income or excise tax.

Unless a shareholder specifies otherwise, all distributions from the fund to
that shareholder will be automatically reinvested in additional full and
fractional shares of the fund. For U.S. federal income tax purposes, all
dividends generally are taxable whether a shareholder takes them in cash or
reinvests them in additional shares of the fund. In general, assuming that the
fund has sufficient earnings and profits, dividends from net investment income
and net short-term capital gains are taxable either as ordinary income or, if
certain conditions are met, as "qualified dividend income," taxable to
individual and certain other noncorporate shareholders at U.S. federal income
tax rates of up to 20%.

The fund invests primarily in debt securities. However, a portion of the
dividend distributions to individuals and certain other noncorporate
shareholders may qualify for U.S. federal income tax rates of up to 20% on
dividends to the extent that such dividends are attributable to qualified
dividend income received by the fund. Qualified dividend income generally means
dividend income received from the fund's investments, if any, in common and
preferred stock of U.S. companies and stock of certain qualified foreign
corporations, provided that certain holding period and other requirements are
met by both the fund and the shareholders. The fund is permitted to acquire
debt securities that are convertible to equity under certain circumstances, and
it is therefore possible that a portion of the fund's distributions may be
eligible for treatment as qualified dividend income.

A foreign corporation is treated as a qualified foreign corporation for this
purpose if it is incorporated in a possession of the United States or it is
eligible for the benefits of certain income tax treaties with the United States
and meets certain additional requirements. Certain foreign corporations that
are not otherwise qualified foreign corporations will be treated as qualified
foreign corporations with respect to dividends paid by them if the stock with
respect to which the dividends are paid is readily tradable on an established
securities market in the United States. Passive foreign investment companies
are not qualified foreign corporations for this purpose. Dividends received by
the fund from REITs generally are not expected to qualify for treatment as
qualified dividend income.

A dividend that is attributable to qualified dividend income of the fund that
is paid by the fund to a shareholder will not be taxable as qualified dividend
income to such shareholder (1) if the dividend is received with respect to any
share of the fund held for fewer than 61 days during the 121-day period


                                       75


beginning on the date which is 60 days before the date on which such share
became ex-dividend with respect to such dividend, (2) to the extent that the
shareholder is under an obligation (whether pursuant to a short sale or
otherwise) to make related payments with respect to positions in substantially
similar or related property, or (3) if the shareholder elects to have the
dividend treated as investment income for purposes of the limitation on
deductibility of investment interest. The "ex-dividend" date is the date on
which the owner of the share at the commencement of such date is entitled to
receive the next issued dividend payment for such share even if the share is
sold by the owner on that date or thereafter.

Distributions by the fund in excess of the fund's current and accumulated
earnings and profits will be treated as a return of capital to the extent of
(and in reduction of) the shareholder's tax basis in its shares and any such
amount in excess of that basis will be treated as gain from the sale of shares,
as discussed below.

Certain dividends received by the fund from U.S. corporations (generally,
dividends received by the fund in respect of any share of stock (1) with a tax
holding period of at least 46 days during the 91-day period beginning on the
date that is 45 days before the date on which the stock becomes ex-dividend as
to that dividend and (2) that is held in an unleveraged position) and
distributed and appropriately so reported by the fund may be eligible for the
70% dividends-received deduction generally available to corporations under the
Code. Certain preferred stock must have a holding period of at least 91 days
during the 181-day period beginning on the date that is 90 days before the date
on which the stock becomes ex-dividend as to that dividend in order to be
eligible. Capital gain dividends distributed to the fund from other regulated
investment companies are not eligible for the dividends-received deduction. The
fund is permitted to acquire stock of U.S. domestic corporations, and it is
therefore possible that a portion of the fund's distributions may qualify for
this deduction. In order to qualify for the deduction, corporate shareholders
must meet the minimum holding period requirement stated above with respect to
their fund shares, taking into account any holding period reductions from
certain hedging or other transactions or positions that diminish their risk of
loss with respect to their fund shares, and, if they borrow to acquire or
otherwise incur debt attributable to fund shares, they may be denied a portion
of the dividends-received deduction with respect to those shares. The entire
dividend, including the otherwise deductible amount, will be included in
determining the excess, if any, of a corporation's adjusted current earnings
over its alternative minimum taxable income, which may increase a corporation's
alternative minimum tax liability. Any corporate shareholder should consult its
tax adviser regarding the possibility that its tax basis in its shares may be
reduced, for U.S. federal income tax purposes, by reason of "extraordinary
dividends" received with respect to the shares and, to the extent such basis
would be reduced below zero, current recognition of income may be required.

Distributions from net capital gains, if any, that are reported as capital gain
dividends by the fund are taxable as long-term capital gains for U.S. federal
income tax purposes without regard to the length of time the shareholder has
held shares of the fund. Capital gain dividends distributed by the fund to
individual and certain other noncorporate shareholders will be taxed as
long-term capital gains, which are generally taxable to noncorporate taxpayers
at U.S. federal income tax rates of up to 20%. A shareholder should also be
aware that the benefits of the favorable tax rates applicable to long-term
capital gains and qualified dividend income may be affected by the application
of the alternative minimum tax to individual shareholders.

The U.S. federal income tax status of all distributions will be reported to
shareholders annually.

A 3.8% Medicare contribution tax generally applies to all or a portion of the
net investment income of a shareholder who is an individual and not a
nonresident alien for federal income tax purposes and who has adjusted gross
income (subject to certain adjustments) that exceeds a threshold amount
($250,000 if married filing jointly or if considered a "surviving spouse" for
federal income tax purposes, $125,000 if married filing separately, and
$200,000 in other cases). This 3.8% tax also applies to all or a portion of


                                       76


the undistributed net investment income of certain shareholders that are
estates and trusts. For these purposes, interest, dividends and certain capital
gains (among other categories of income) are generally taken into account in
computing a shareholder's net investment income.

Although dividends generally will be treated as distributed when paid, any
dividend declared by the fund in October, November or December and payable to
shareholders of record in such a month that is paid during the following
January will be treated for U.S. federal income tax purposes as received by
shareholders on December 31 of the calendar year in which it was declared. In
addition, certain distributions made after the close of a taxable year of the
fund may be "spilled back" and treated for certain purposes as paid by the fund
during such taxable year. In such case, shareholders generally will be treated
as having received such dividends in the taxable year in which the
distributions were actually made. For purposes of calculating the amount of a
regulated investment company's undistributed income and gain subject to the 4%
excise tax described above, such "spilled back" dividends are treated as paid
by the regulated investment company when they are actually paid.

For U.S. federal income tax purposes, the fund is permitted to carry forward
indefinitely a net capital loss from any taxable year that began after December
22, 2010 to offset its capital gains, if any, in years following the year of
the loss. To the extent subsequent capital gains are offset by such losses,
they will not result in U.S. federal income tax liability to the fund and may
not be distributed as capital gains to shareholders. See "Annual Fee, Expense
and Other Information" for the fund's available capital loss carryforwards.
Generally, the fund may not carry forward any losses other than net capital
losses. Under certain circumstances, the fund may elect to treat certain losses
as though they were incurred on the first day of the taxable year immediately
following the taxable year in which they were actually incurred.

At the time of an investor's purchase of fund shares, a portion of the purchase
price may be attributable to realized or unrealized appreciation in the fund's
portfolio or to undistributed capital gains of the fund. Consequently,
subsequent distributions by the fund with respect to these shares from such
appreciation or gains may be taxable to such investor even if the net asset
value of the investor's shares is, as a result of the distributions, reduced
below the investor's cost for such shares and the distributions economically
represent a return of a portion of the investment.

Redemptions and exchanges generally are taxable events for shareholders that
are subject to tax. Shareholders should consult their own tax advisers with
reference to their individual circumstances to determine whether any particular
transaction in fund shares is properly treated as a sale for tax purposes, as
the following discussion assumes, and to ascertain the tax treatment of any
gains or losses recognized in such transactions. In general, if fund shares are
sold, the shareholder will recognize gain or loss equal to the difference
between the amount realized on the sale and the shareholder's adjusted basis in
the shares. Such gain or loss generally will be treated as long-term capital
gain or loss if the shares were held for more than one year and otherwise
generally will be treated as short-term capital gain or loss. Any loss
recognized by a shareholder upon the redemption, exchange or other disposition
of shares with a tax holding period of six months or less will be treated as a
long-term capital loss to the extent of any amounts treated as distributions to
the shareholder of long-term capital gain with respect to such shares
(including any amounts credited to the shareholder as undistributed capital
gains).

The fund will report to the Internal Revenue Service (the "IRS") the amount of
sale proceeds that a shareholder receives from a sale or exchange of fund
shares. For sales or exchanges of shares acquired on or after January 1, 2012,
the fund will also report the shareholder's basis in those shares and whether
any gain or loss that the shareholder realizes on the sale or exchange is
short-term or long-term gain or loss. For purposes of calculating and reporting
basis, shares acquired prior to January 1, 2012 and shares acquired on or after
January 1, 2012 will generally be treated as held in separate accounts. If a
shareholder has a different basis for different shares of the fund, acquired on
or after January 1, 2012, in the same account (e.g., if a shareholder purchased
fund shares in the same account at different times for different prices), the
fund will calculate the basis of the shares sold using its default method
unless the


                                       77


shareholder has properly elected to use a different method. The fund's default
method for calculating basis will be the average basis method, under which the
basis per share is reported as the average of the bases of all of the
shareholder's fund shares in the account. A shareholder may elect, on an
account-by-account basis, to use a method other than average basis by following
procedures established by the fund. If such an election is made on or prior to
the date of the first exchange or redemption of shares in the account and on or
prior to the date that is one year after the shareholder receives notice of the
fund's default method, the new election will generally apply as if the average
basis method had never been in effect for such account. If such an election is
not made on or prior to such dates, the shares in the account at the time of
the election will retain their averaged bases. Shareholders should consult
their tax advisers concerning the tax consequences of applying the average
basis method or electing another method of basis calculation.

Losses on redemptions or other dispositions of shares may be disallowed under
"wash sale" rules in the event of other investments in the fund (including
those made pursuant to reinvestment of dividends and/or capital gain
distributions) within a period of 61 days beginning 30 days before and ending
30 days after a redemption or other disposition of shares. In such a case, the
disallowed portion of any loss generally would be included in the U.S. federal
tax basis of the shares acquired in the other investments.

Gain may be increased (or loss reduced) upon a redemption of Class A shares of
the fund within 90 days after their purchase followed by any purchase
(including purchases by exchange or by reinvestment), without payment of an
additional sales charge, of Class A shares of the fund or of another Pioneer
fund (or any other shares of a Pioneer fund generally sold subject to a sales
charge) before February 1 of the calendar year following the calendar year in
which the original Class A shares were redeemed.

Under Treasury regulations, if a shareholder recognizes a loss with respect to
fund shares of $2 million or more for an individual shareholder, or $10 million
or more for a corporate shareholder, in any single taxable year (or certain
greater amounts over a combination of years), the shareholder must file with
the IRS a disclosure statement on IRS Form 8886. Shareholders who own portfolio
securities directly are in many cases excepted from this reporting requirement
but, under current guidance, shareholders of regulated investment companies are
not excepted. A shareholder who fails to make the required disclosure to the
IRS may be subject to substantial penalties. The fact that a loss is reportable
under these regulations does not affect the legal determination of whether or
not the taxpayer's treatment of the loss is proper. Shareholders should consult
with their tax advisers to determine the applicability of these regulations in
light of their individual circumstances.

Shareholders that are exempt from U.S. federal income tax, such as retirement
plans that are qualified under Section 401 of the Code, generally are not
subject to U.S. federal income tax on fund dividends or distributions, or on
sales or exchanges of fund shares unless the fund shares are "debt-financed
property" within the meaning of the Code. However, in the case of fund shares
held through a non-qualified deferred compensation plan, fund dividends and
distributions received by the plan and gains from sales and exchanges of fund
shares by the plan generally are taxable to the employer sponsoring such plan
in accordance with the U.S. federal income tax laws that are generally
applicable to shareholders receiving such dividends or distributions from
regulated investment companies such as the fund.

A plan participant whose retirement plan invests in the fund, whether such plan
is qualified or not, generally is not taxed on fund dividends or distributions
received by the plan or on gains from sales or exchanges of fund shares by the
plan for U.S. federal income tax purposes. However, distributions to plan
participants from a retirement plan account generally are taxable as ordinary
income, and different tax treatment, including penalties on certain excess
contributions and deferrals, certain pre-retirement and post-retirement
distributions and certain prohibited transactions, is accorded to accounts
maintained as qualified retirement plans. Shareholders should consult their tax
advisers for more information.


                                       78


Foreign exchange gains and losses realized by the fund in connection with
certain transactions involving foreign currency-denominated debt securities,
certain options and futures contracts relating to foreign currency, foreign
currency forward contracts, foreign currencies, or payables or receivables
denominated in a foreign currency are subject to Section 988 of the Code, which
generally causes such gains and losses to be treated as ordinary income and
losses and may affect the amount, timing and character of distributions to
shareholders. Under Treasury regulations that may be promulgated in the future,
any gains from such transactions that are not directly related to the fund's
principal business of investing in stock or securities (or its options
contracts or futures contracts with respect to stock or securities) may have to
be limited in order to enable the fund to satisfy the 90% income test.

If the fund acquires any equity interest (under Treasury regulations that may
be promulgated in the future, generally including not only stock but also an
option to acquire stock such as is inherent in a convertible bond) in certain
foreign corporations (i) that receive at least 75% of their annual gross income
from passive sources (such as interest, dividends, certain rents and royalties,
or capital gains) or (ii) where at least 50% of the corporation's assets
(computed based on average fair market value) either produce or are held for
the production of passive income ("passive foreign investment companies"), the
fund could be subject to U.S. federal income tax and additional interest
charges on "excess distributions" received from such companies or on gain from
the sale of stock in such companies, even if all income or gain actually
received by the fund is timely distributed to its shareholders. The fund would
not be able to pass through to its shareholders any credit or deduction for
such a tax. A "qualified electing fund" election or a "mark to market" election
may be available that would ameliorate these adverse tax consequences, but such
elections could require the fund to recognize taxable income or gain (subject
to the distribution requirements applicable to regulated investment companies,
as described above) without the concurrent receipt of cash. In order to satisfy
the distribution requirements and avoid a tax on the fund, the fund may be
required to liquidate portfolio securities that it might otherwise have
continued to hold, potentially resulting in additional taxable gain or loss to
the fund. Gains from the sale of stock of passive foreign investment companies
may also be treated as ordinary income. In order for the fund to make a
qualified electing fund election with respect to a passive foreign investment
company, the passive foreign investment company would have to agree to provide
certain tax information to the fund on an annual basis, which it might not
agree to do. The fund may limit and/or manage its holdings in passive foreign
investment companies to limit its tax liability or maximize its return from
these investments.

The fund may invest in or hold debt obligations of issuers not currently paying
interest or that are in default. Investments in debt obligations that are at
risk of or are in default present special tax issues for the fund. Federal
income tax rules are not entirely clear about issues such as when the fund may
cease to accrue interest, original issue discount or market discount, when and
to what extent deductions may be taken for bad debts or worthless securities,
how payments received on obligations in default should be allocated between
principal and interest and whether certain exchanges of debt obligations in a
workout context are taxable. These and other issues will be addressed by the
fund, in the event it invests in or holds such securities, in order to seek to
ensure that it distributes sufficient income to preserve its status as a
regulated investment company and does not become subject to U.S. federal income
or excise tax.

If the fund invests in certain pay-in-kind securities, zero coupon securities,
deferred interest securities or, in general, any other securities with original
issue discount (or with market discount if the fund elects to include market
discount in income currently), the fund generally must accrue income on such
investments for each taxable year, which generally will be prior to the receipt
of the corresponding cash payments. However, the fund must distribute to its
shareholders, at least annually, all or substantially all of its investment
company taxable income (determined without regard to the deduction for
dividends paid), including such accrued income, to qualify to be treated as a
regulated investment company under the Code and avoid U.S. federal income and
excise taxes. Therefore, the fund may have to dispose of its


                                       79


portfolio securities, potentially under disadvantageous circumstances, to
generate cash, or may have to borrow the cash, to satisfy distribution
requirements. Such a disposition of securities may potentially result in
additional taxable gain or loss to the fund.

Options written or purchased and futures contracts entered into by the fund on
certain securities, indices and foreign currencies, as well as certain forward
foreign currency contracts, may cause the fund to recognize gains or losses
from marking-to-market even though such options may not have lapsed or been
closed out or exercised, or such futures or forward contracts may not have been
performed or closed out. The tax rules applicable to these contracts may affect
the characterization of some capital gains and losses realized by the fund as
long-term or short-term. Certain options, futures and forward contracts
relating to foreign currency may be subject to Section 988 of the Code, as
described above, and accordingly may produce ordinary income or loss.
Additionally, the fund may be required to recognize gain if an option, futures
contract, forward contract, short sale or other transaction that is not subject
to the mark-to-market rules is treated as a "constructive sale" of an
"appreciated financial position" held by the fund under Section 1259 of the
Code. Any net mark-to-market gains and/or gains from constructive sales may
also have to be distributed to satisfy the distribution requirements referred
to above even though the fund may receive no corresponding cash amounts,
possibly requiring the disposition of portfolio securities or borrowing to
obtain the necessary cash. Such a disposition of securities may potentially
result in additional taxable gain or loss to the fund. Losses on certain
options, futures or forward contracts and/or offsetting positions (portfolio
securities or other positions with respect to which the fund's risk of loss is
substantially diminished by one or more options, futures or forward contracts)
may also be deferred under the tax straddle rules of the Code, which may also
affect the characterization of capital gains or losses from straddle positions
and certain successor positions as long-term or short-term. Certain tax
elections may be available that would enable the fund to ameliorate some
adverse effects of the tax rules described in this paragraph. The tax rules
applicable to options, futures, forward contracts and straddles may affect the
amount, timing and character of the fund's income and gains or losses and hence
of its distributions to shareholders.

The fund may be subject to withholding and other taxes imposed by foreign
countries, including taxes on interest, dividends and capital gains with
respect to its investments in those countries. Any such taxes would, if
imposed, reduce the yield on or return from those investments. Tax conventions
between certain countries and the U.S. may reduce or eliminate such taxes in
some cases. The fund does not expect to satisfy the requirements for passing
through to its shareholders any share of foreign taxes paid by the fund, with
the result that shareholders will not include such taxes in their gross incomes
and will not be entitled to a tax deduction or credit for such taxes on their
own tax returns.

The fund is required to withhold (as "backup withholding") a portion of
reportable payments, including dividends, capital gain distributions and the
proceeds of redemptions and exchanges or repurchases of fund shares, paid to
shareholders who have not complied with certain IRS regulations. The backup
withholding rate is 28%. In order to avoid this withholding requirement,
shareholders, other than certain exempt entities, must generally certify that
the Social Security Number or other Taxpayer Identification Number they provide
is their correct number and that they are not currently subject to backup
withholding, or that they are exempt from backup withholding. The fund may
nevertheless be required to backup withhold if it receives notice from the IRS
or a broker that the number provided is incorrect or backup withholding is
applicable as a result of previous underreporting of interest or dividend
income.

The description of certain federal tax provisions above relates only to U.S.
federal income tax consequences for shareholders who are U.S. persons, i.e.,
generally, U.S. citizens or residents or U.S. corporations, partnerships,
trusts or estates, and who are subject to U.S. federal income tax and hold
their shares as capital assets. Except as otherwise provided, this description
does not address the special tax rules that may be applicable to particular
types of investors, such as financial institutions, insurance companies,
securities dealers, other regulated investment companies, or tax-exempt or
tax-deferred plans, accounts or entities. Investors other than U.S. persons may
be subject to different U.S.


                                       80


federal income tax treatment, including a non-resident alien U.S. withholding
tax at the rate of 30% or any lower applicable treaty rate on amounts treated
as ordinary dividends from the fund or, in certain circumstances, unless an
effective IRS Form W-8BEN or other authorized withholding certificate is on
file, to backup withholding on certain other payments from the fund. Backup
withholding will not be applied to payments that have been subject to the 30%
(or lower applicable treaty rate) withholding tax on shareholders who are
neither citizens nor residents of the United States.

Unless certain non-U.S. entities that hold fund shares comply with IRS
requirements that will generally require them to report information regarding
U.S. persons investing in, or holding accounts with, such entities, a 30%
withholding tax may apply to fund distributions payable to such entities after
June 30, 2014 (or, in certain cases, after later dates) and redemptions and
certain capital gain dividends payable to such entities after December 31,
2018. A non-U.S. shareholder may be exempt from the withholding described in
this paragraph under an applicable intergovernmental agreement between the U.S.
and a foreign government, provided that the shareholder and the applicable
foreign government comply with the terms of such agreement.

Shareholders should consult their own tax advisers on these matters and on
state, local, foreign and other applicable tax laws.

If, as anticipated, the fund qualifies as a regulated investment company under
the Code, it will not be required to pay any Massachusetts income, corporate
excise or franchise taxes or any Delaware corporation income tax.

A state income (and possibly local income and/or intangible property) tax
exemption is generally available to the extent the fund's distributions are
derived from interest on (or, in the case of intangible property taxes, to the
extent the value of its assets is attributable to) certain U.S. government
obligations, provided in some states that certain thresholds for holdings of
such obligations and/or reporting requirements are satisfied. The fund will not
seek to satisfy any threshold or reporting requirements that may apply in
particular taxing jurisdictions, although the fund may in its sole discretion
provide relevant information to shareholders.

19. APPENDIX A - DESCRIPTION OF SHORT-TERM DEBT, CORPORATE BOND AND PREFERRED
STOCK RATINGS/1/


DESCRIPTION OF MOODY'S INVESTORS SERVICE, INC.'S ("MOODY'S") SHORT-TERM
RATINGS:
Moody's short-term ratings are forward-looking opinions of the ability of
issuers to honor short-term financial obligations. Ratings may be assigned to
issuers, short-term programs or to individual short-term debt instruments. Such
obligations generally have an original maturity of thirteen months or less and
reflect the likelihood of a default on contractually promised payments.

Moody's employs the following designations to indicate the relative repayment
ability of rated issuers:

P-1: Issuers (or supporting institutions) rated Prime-1 have a superior ability
to repay short-term debt obligations.

P-2: Issuers (or supporting institutions) rated Prime-2 have a strong ability
to repay short-term debt obligations.

P-3: Issuers (or supporting institutions) rated Prime-3 have an acceptable
ability to repay short-term obligations.

NP: Issuers (or supporting institutions) rated Not Prime do not fall within any
of the Prime rating categories.

NOTE: Canadian issuers rated P-1 or P-2 have their short-term ratings enhanced
by the senior-most long-term rating of the issuer, its guarantor or
support-provider.


DESCRIPTION OF MOODY'S LONG-TERM CORPORATE RATINGS:
Moody's long-term obligation ratings are forward-looking opinions of the
relative credit risk of fixed-income obligations with an original maturity of
one year or more. They address the possibility that a financial obligation will
not be honored as promised. Such ratings use Moody's Global Long-Term Rating
Scale and reflect both on the likelihood of default on contractually promised
payments and the expected financial loss suffered in the event of default.

AAA: Obligations rated Aaa are judged to be of the highest quality, subject to
the lowest level of credit risk.

AA: Obligations rated Aa are judged to be of high quality and are subject to
very low credit risk.

A: Obligations rated A are considered upper-medium grade and are subject to low
   credit risk.

BAA: Obligations rated Baa are judged to be medium-grade and subject to
moderate credit risk, and as such may possess certain speculative
characteristics.

BA: Obligations rated Ba are judged to be speculative and are subject to
substantial credit risk.

B: Obligations rated B are considered speculative and are subject to high
   credit risk.

CAA: Obligations rated Caa are judged to be speculative and of poor standing
and are subject to very high credit risk.
------------------------
/1/ The ratings indicated herein are believed to be the most recent ratings
   available at the date of this statement of additional information for the
   securities listed. Ratings are generally given to securities at the time of
   issuance. While the rating agencies may from time to time revise such
   ratings, they undertake no obligation to do so, and the ratings indicated
   do not necessarily represent ratings which will be given to these
   securities on the date of the fund's fiscal year-end.


                                       86


CA: Obligations rated Ca are highly speculative and are likely in, or very
near, default, with some prospect of recovery of principal and interest.

C: Obligations rated C are the lowest rated class of bonds and are typically in
default, with little prospect for recovery of principal or interest.

NOTE: Moody's appends numerical modifiers "1", "2", and "3" to each generic
rating classification from "Aa" through "Caa". The modifier "1" indicates that
the obligation ranks in the higher end of its generic rating category; the
modifier "2" indicates a mid-range ranking; and the modifier "3" indicates a
ranking in the lower end of that generic rating category. Additionally, a
"(hyb)" indicator is appended to all ratings of hybrid securities issued by
banks, finance companies and securities firms.


STANDARD & POOR'S RATINGS GROUP'S LONG-TERM ISSUE CREDIT RATINGS:
Issue credit ratings are based, in varying degrees, on Standard & Poor's
analysis of the following considerations:

o Likelihood of payment-capacity and willingness of the obligor to meet its
  financial commitment on an obligation in accordance with the terms of the
  obligation;

o Nature of and provisions of the obligation;

o Protection afforded by, and relative position of, the obligation in the event
  of bankruptcy, reorganization, or other arrangement under the laws of
  bankruptcy and other laws affecting creditors' rights.

Issue ratings are an assessment of default risk, but may incorporate an
assessment of relative seniority or ultimate recovery in the event of default.
Junior obligations are typically rated lower than senior obligations, to
reflect the lower priority in bankruptcy, as noted above. (Such differentiation
may apply when an entity has both senior and subordinated obligations, secured
and unsecured obligations, or operating company and holding company
obligations.)

AAA: An obligation rated "AAA" has the highest rating assigned by Standard &
Poor's. The obligor's capacity to meet its financial commitment on the
obligation is extremely strong.

AA: An obligation rated "AA" differs from the highest-rated obligations only to
a small degree. The obligor's capacity to meet its financial commitment on the
obligation is very strong.

A: An obligation rated "A" is somewhat more susceptible to the adverse effects
of changes in circumstances and economic conditions than obligations in
higher-rated categories. However, the obligor's capacity to meet its financial
commitment on the obligation is still strong.

BBB: An obligation rated "BBB" exhibits adequate protection parameters.
However, adverse economic conditions or changing circumstances are more likely
to lead to a weakened capacity of the obligor to meet its financial commitment
on the obligation.

BB, B, CCC, CC, AND C: Obligations rated "BB", "B", "CCC", "CC", and "C" are
regarded as having significant speculative characteristics. "BB" indicates the
least degree of speculation and "C" the highest. While such obligations will
likely have some quality and protective characteristics, these may be
outweighed by large uncertainties or major exposures to adverse conditions.

BB: An obligation rated "BB" is less vulnerable to nonpayment than other
speculative issues. However, it faces major ongoing uncertainties or exposure
to adverse business, financial, or economic conditions which could lead to the
obligor's inadequate capacity to meet its financial commitment on the
obligation.

B: An obligation rated "B" is more vulnerable to nonpayment than obligations
rated "BB", but the obligor currently has the capacity to meet its financial
commitment on the obligation. Adverse business, financial, or economic
conditions will likely impair the obligor's capacity or willingness to meet its
financial commitment on the obligation.

                                       87


CCC: An obligation rated "CCC" is currently vulnerable to nonpayment, and is
dependent upon favorable business, financial, and economic conditions for the
obligor to meet its financial commitment on the obligation. In the event of
adverse business, financial, or economic conditions, the obligor is not likely
to have the capacity to meet its financial commitment on the obligation.

CC: An obligation rated "CC" is currently highly vulnerable to nonpayment.

C: A "C" rating is assigned to obligations that are currently highly vulnerable
to nonpayment, obligations that have payment arrearages allowed by the terms of
the documents, or obligations of an issuer that is the subject of a bankruptcy
petition or similar action which have not experienced a payment default. Among
others, the "C" rating may be assigned to subordinated debt, preferred stock or
other obligations on which cash payments have been suspended in accordance with
the instrument's terms or when preferred stock is the subject of a distressed
exchange offer, whereby some or all of the issue is either repurchased for an
amount of cash or replaced by other instruments having a total value that is
less than par.

D: An obligation rated "D" is in payment default. The "D" rating category is
used when payments on an obligation, including a regulatory capital instrument,
are not made on the date due even if the applicable grace period has not
expired, unless Standard & Poor's believes that such payments will be made
during such grace period. The "D" rating also will be used upon the filing of a
bankruptcy petition or the taking of a similar action if payments on an
obligation are jeopardized. An obligation's rating is lowered to "D" upon
completion of a distressed exchange offer, whereby some or all of the issue is
either repurchased for an amount of cash or replaced by other instruments
having a total value that is less than par.

PLUS (+) OR MINUS (-): The ratings from "AA" to "CCC" may be modified by the
addition of a plus (+) or minus (-) sign to show relative standing within the
major rating categories.

NR: This indicates that no rating has been requested, that there is
insufficient information on which to base a rating, or that Standard & Poor's
does not rate a particular obligation as a matter of policy.


STANDARD & POOR'S SHORT-TERM ISSUE CREDIT RATINGS:
Short-term ratings are generally assigned to those obligations considered
short-term in the relevant market. In the U.S., for example, that means
obligations with an original maturity date of no more than 365 days - including
commercial paper. Short-term ratings are also used to indicate the
creditworthiness of an obligor with respect to put features on long-term
obligations. The result is a dual rating, in which the short-term rating
addresses the put feature, in addition to the usual long-term rating.

A-1: A short-term obligation rated "A-1" is rated in the highest category by
Standard & Poor's. The obligor's capacity to meet its financial commitment on
the obligation is strong. Within this category, certain obligations are
designated with a plus sign (+). This indicates that the obligor's capacity to
meet its financial commitment on these obligations is extremely strong.

A-2: A short-term obligation rated "A-2" is somewhat more susceptible to the
adverse effects of changes in circumstances and economic conditions than
obligations in higher rating categories. However, the obligor's capacity to
meet its financial commitment on the obligation is satisfactory.

A-3: A short-term obligation rated "A-3" exhibits adequate protection
parameters. However, adverse economic conditions or changing circumstances are
more likely to lead to a weakened capacity of the obligor to meet its financial
commitment on the obligation.

                                       88


B: A short-term obligation rated "B" is regarded as having significant
speculative characteristics. Ratings of "B-1", "B-2", and "B-3" may be assigned
to indicate finer distinctions within the "B" category. The obligor currently
has the capacity to meet its financial commitment on the obligation; however,
it faces major ongoing uncertainties which could lead to the obligor's
inadequate capacity to meet its financial commitment on the obligation.

B-1: A short-term obligation rated "B-1" is regarded as having significant
speculative characteristics, but the obligor has a relatively stronger capacity
to meet its financial commitments over the short-term compared to other
speculative-grade obligors.

B-2: A short-term obligation rated "B-2" is regarded as having significant
speculative characteristics, and the obligor has an average speculative-grade
capacity to meet its financial commitments over the short-term compared to
other speculative-grade obligors.

B-3: A short-term obligation rated "B-3" is regarded as having significant
speculative characteristics, and the obligor has a relatively weaker capacity
to meet its financial commitments over the short-term compared to other
speculative-grade obligors.

C: A short-term obligation rated "C" is currently vulnerable to nonpayment and
is dependent upon favorable business, financial, and economic conditions for
the obligor to meet its financial commitment on the obligation.

D: A short-term obligation rated "D" is in payment default. The "D" rating
category is used when payments on an obligation, including a regulatory capital
instrument, are not made on the date due even if the applicable grace period
has not expired, unless Standard & Poor's believes that such payments will be
made during such grace period. The "D" rating also will be used upon the filing
of a bankruptcy petition or the taking of a similar action if payments on an
obligation are jeopardized.


LOCAL CURRENCY AND FOREIGN CURRENCY RISKS
Country risk considerations are a standard part of Standard & Poor's analysis
for credit ratings on any issuer or issue. Currency of repayment is a key
factor in this analysis. An obligor's capacity to repay foreign currency
obligations may be lower than its capacity to repay obligations in its local
currency due to the sovereign government's own relatively lower capacity to
repay external versus domestic debt. These sovereign risk considerations are
incorporated in the debt ratings assigned to specific issues. Foreign currency
issuer ratings are also distinguished from local currency issuer ratings to
identify those instances where sovereign risks make them different for the same
issuer.



                                       89


20. APPENDIX B - PROXY VOTING POLICIES AND PROCEDURES


POLICY
Each of Pioneer Investment Management, Inc. and Pioneer Institutional Asset
Management, Inc. (collectively, "Pioneer") is a fiduciary that owes each of its
clients the duties of care and loyalty with respect to all services undertaken
on the client's behalf, including voting proxies for securities held by the
client. When Pioneer has been delegated proxy-voting authority for a client,
the duty of care requires Pioneer to monitor corporate events and to vote the
proxies. To satisfy its duty of loyalty, Pioneer must place the client's
interests ahead of its own and must cast proxy votes in a manner consistent
with the best interest of the client. It is Pioneer's policy to vote proxies
presented to Pioneer in a timely manner in accordance with these principles.

Pioneer's sole concern in voting proxies is the economic effect of the proposal
on the value of portfolio holdings, considering both the short- and long-term
impact. In many instances, Pioneer believes that supporting the company's
strategy and voting "for" management's proposals builds portfolio value. In
other cases, however, proposals set forth by management may have a negative
effect on that value, while some shareholder proposals may hold the best
prospects for enhancing it. Pioneer monitors developments in the proxy-voting
arena and will revise this policy as needed.

Pioneer's clients may request copies of their proxy voting records and of
Pioneer's proxy voting policies and procedures by either sending a written
request to Pioneer's Proxy Coordinator, or clients may review Pioneer's proxy
voting policies and procedures online at pioneerinvestments.com. Pioneer may
describe to clients its proxy voting policies and procedures by delivering a
copy of Pioneer's Form ADV (Part II), by separate notice to the client or by
other means.


APPLICABILITY
This Proxy Voting policy and the procedures set forth below are designed to
complement Pioneer's investment policies and procedures regarding its general
responsibility to monitor the performance and/or corporate events of companies
that are issuers of securities held in accounts managed by Pioneer. This policy
sets forth Pioneer's position on a number of issues for which proxies may be
solicited, but it does not include all potential voting scenarios or proxy
events. Furthermore, because of the special issues associated with proxy
solicitations by closed-end Funds, Pioneer will vote shares of closed-end Funds
on a case-by-case basis.


PURPOSE
The purposes of this policy is to ensure that proxies for United States ("US")
and non-US companies that are received in a timely manner will be voted in
accordance with the principles stated above. Unless the Proxy Voting Oversight
Group (as described below) specifically determines otherwise, all shares in a
company held by Pioneer-managed accounts for which Pioneer has proxy-voting
authority will be voted alike, unless a client has given specific voting
instructions on an issue.

Pioneer does not delegate the authority to vote proxies relating to securities
held by its clients to any of its affiliates, which include other subsidiaries
of UniCredit S.p.A. ("UniCredit").

Any questions about this policy should be directed to Pioneer's Director of
Investment Operations (the "Proxy Coordinator").

                                       90


PROCEDURES


PROXY VOTING SERVICE
Pioneer has engaged an independent proxy voting service to assist in the voting
of proxies. The proxy voting service works with custodians to ensure that all
proxy materials are received by the custodians and are processed in a timely
fashion. To the extent applicable, the proxy voting service votes all proxies
in accordance with the proxy voting guidelines established by Pioneer and set
forth herein. The proxy voting service will refer proxy questions to the Proxy
Coordinator (described below) for instructions under circumstances where: (1)
the application of the proxy voting guidelines is unclear; (2) a particular
proxy question is not covered by the guidelines; or (3) the guidelines call for
specific instructions on a case-by-case basis. The proxy voting service is also
requested to call to the Proxy Coordinator's attention specific proxy questions
that, while governed by a guideline, appear to involve unusual or controversial
issues. Pioneer reserves the right to attend a meeting in person and may do so
when it determines that the company or the matters to be voted on at the
meeting are strategically important to its clients.


PROXY COORDINATOR
The Proxy Coordinator coordinates the voting, procedures and reporting of
proxies on behalf of Pioneer's clients. The Proxy Coordinator will deal
directly with the proxy voting service and, in the case of proxy questions
referred by the proxy voting service, will solicit voting recommendations and
instructions from the Portfolio Management Group or, to the extent applicable,
investment sub-advisers. The Proxy Coordinator is responsible for ensuring that
these questions and referrals are responded to in a timely fashion and for
transmitting appropriate voting instructions to the proxy voting service. The
Proxy Coordinator is responsible for verifying with the Chief Legal Officer or
his or her designee whether Pioneer's voting power is subject to any
limitations or guidelines issued by the client (or in the case of an employee
benefit plan, the plan's trustee or other fiduciaries).


REFERRAL ITEMS
The proxy voting service will refer proxy questions to the Proxy Coordinator or
his or her designee that are described by Pioneer's proxy voting guidelines as
to be voted on a case-by-case basis, that are not covered by Pioneer's
guidelines or where Pioneer's guidelines may be unclear with respect to the
matter to be voted on. Under such circumstances, the Proxy Coordinator will
seek a written voting recommendation from the Head of Portfolio Management U.S.
or his or her designated equity portfolio-management representative. Any such
recommendation will include: (i) the manner in which the proxies should be
voted; (ii) the rationale underlying any such decision; and (iii) the
disclosure of any contacts or communications made between Pioneer and any
outside parties concerning the proxy proposal prior to the time that the voting
instructions are provided.


SECURITIES LENDING
In accordance with industry standards, proxies are not available to be voted
when the shares are out on loan through either Pioneer's lending program or a
client's managed security lending program. However, Pioneer will reserve the
right to recall lent securities so that they may be voted according to the
Pioneer's instructions. If a portfolio manager would like to vote a block of
previously lent shares, the Proxy Coordinator will work with the portfolio
manager and Investment Operations to recall the security, to the extent
possible, to facilitate the vote on the entire block of shares. Certain clients
participate in securities lending programs. Although such programs allow for
the recall of securities for any reason, Pioneer may determine not to vote
securities on loan and it may not always be possible for securities on loan to
be recalled in time to be voted.

                                       91


SHARE-BLOCKING
"Share-blocking" is a market practice whereby shares are sent to a custodian
(which may be different than the account custodian) for record keeping and
voting at the general meeting. The shares are unavailable for sale or delivery
until the end of the blocking period (typically the day after general meeting
date).

Pioneer will vote in those countries with "share-blocking." In the event a
manager would like to sell a security with "share-blocking", the Proxy
Coordinator will work with the Portfolio Manager and Investment Operations
Department to recall the shares (as allowable within the market time frame and
practices) and/or communicate with executing brokerage firm. A list of
countries with "share-blocking" is available from the Investment Operations
Department upon request.


PROXY VOTING OVERSIGHT GROUP
The members of the Proxy Voting Oversight Group include Pioneer's Head of
Portfolio Management U.S. or his or her designated equity portfolio management
representative, the Director of Investment Operations, and the Chief Compliance
Officer of the Adviser and Funds. Other members of Pioneer will be invited to
attend meetings and otherwise participate as necessary. The Director of
Investment Operations will chair the Proxy Voting Oversight Group.

The Proxy Voting Oversight Group is responsible for developing, evaluating, and
changing (when necessary) Pioneer's proxy voting policies and procedures. The
group meets at least annually to evaluate and review this policy and procedures
and the services of its third-party proxy voting service. In addition, the
Proxy Voting Oversight Group will meet as necessary to vote on referral items
and address other business as necessary.


AMENDMENTS
Pioneer may not amend this policy without the prior approval of the Proxy
Voting Oversight Group and its corporate parent, Pioneer Global Asset
Management S.p.A. ("PGAM").


FILING FORM N-PX
The Proxy Coordinator and the Regulatory Compliance Manager are responsible for
ensuring that Form N-PX documents receive the proper review by a member of the
Proxy Voting Oversight Group prior to a Fund officer signing the forms.

The Investment Operations department will provide the Compliance department
with a copy of each Form N-PX filing prepared by the proxy voting service.

COMPLIANCE FILES N-PX.

The Compliance department will ensure that a corresponding Form N-PX exists for
each Pioneer registered investment company.

Following this review, each Form N-PX is formatted for public dissemination via
the EDGAR system.

Prior to submission, each Form N-PX is to be presented to the Fund officer for
a final review and signature.

Copies of the Form N-PX filings and their submission receipts are maintained
according to Pioneer record keeping policies.


PROXY VOTING GUIDELINES


ADMINISTRATIVE
While administrative items appear infrequently in U.S. issuer proxies, they are
quite common in non-U.S. proxies.

We will generally support these and similar management proposals:

                                       92

o Authorization of the transferring of reserves and allocation of income.

o Amendments to authorized signatories.

o Approval of accounting method changes or change in fiscal year-end.

o Acceptance of labor agreements.

o Appointment of internal auditors.

Pioneer will vote on a case-by-case basis on other routine administrative
items; however, Pioneer will oppose any routine proposal if insufficient
information is presented in advance to allow Pioneer to judge the merit of the
proposal. Pioneer has also instructed its proxy voting service to inform
Pioneer of its analysis of any administrative items that may be inconsistent,
in its view, with Pioneer's goal of supporting the value of its clients'
portfolio holdings so that Pioneer may consider and vote on those items on a
case-by-case basis.


AUDITORS
We normally vote for proposals to:

o Ratify the auditors. We will consider a vote against if we are concerned
  about the auditors' independence or their past work for the company.
  Specifically, we will oppose the ratification of auditors and withhold votes
  for audit committee members if non-audit fees paid by the company to the
  auditing firm exceed the sum of audit fees plus audit-related fees plus
  permissible tax fees according to the disclosure categories proposed by the
  Securities and Exchange Commission.

o Restore shareholder rights to ratify the auditors.

We will normally oppose proposals that require companies to:

o Seek bids from other auditors.

o Rotate auditing firms, except where the rotation is statutorily required or
  where rotation would demonstrably strengthen financial disclosure.

o Indemnify auditors.

o Prohibit auditors from engaging in non-audit services for the company.


BOARD OF DIRECTORS
On issues related to the board of directors, Pioneer normally supports
management. We will, however, consider a vote against management in instances
where corporate performance has been very poor or where the board appears to
lack independence.


GENERAL BOARD ISSUES
Pioneer will vote for:

o Audit, compensation and nominating committees composed of independent
  directors exclusively.

o Indemnification for directors for actions taken in good faith in accordance
  with the business judgment rule. We will vote against proposals for broader
  indemnification.

                                       93


o Changes in board size that appear to have a legitimate business purpose and
  are not primarily for anti-takeover reasons.

o Election of an honorary director.

We will vote against:

o Minimum stock ownership by directors.

o Term limits for directors. Companies benefit from experienced directors, and
  shareholder control is better achieved through annual votes.

o Requirements for union or special interest representation on the board.

o Requirements to provide two candidates for each board seat.

We will vote on a case-by case basis on these issues:

o Separate chairman and CEO positions. We will consider voting with
  shareholders on these issues in cases of poor corporate performance.


ELECTIONS OF DIRECTORS
In uncontested elections of directors we will vote against:

o Individual directors with absenteeism above 25% without valid reason. We
  support proposals that require disclosure of director attendance.

o Insider directors and affiliated outsiders who sit on the audit,
  compensation, stock option or nominating committees. For the purposes of our
  policy, we accept the definition of affiliated directors provided by our
  proxy voting service.

We will also vote against:

o Directors who have failed to act on a takeover offer where the majority of
  shareholders have tendered their shares.

o Directors who appear to lack independence or are associated with very poor
  corporate performance.

We will vote on a case-by-case basis on these issues:

o Re-election of directors who have implemented or renewed a dead-hand or
  modified dead-hand poison pill (a "dead-hand poison pill" is a shareholder
  rights plan that may be altered only by incumbent or "dead" directors. These
  plans prevent a potential acquirer from disabling a poison pill by obtaining
  control of the board through a proxy vote).

o Contested election of directors.

o Election of a greater number of independent directors (in order to move
  closer to a majority of independent directors in cases of poor performance.

o Mandatory retirement policies.

o Directors who have ignored a shareholder proposal that has been approved by
  shareholders for two consecutive years.

We will vote for:

o Precatory and binding resolutions requesting that the board changes the
  company's bylaws to stipulate that directors need to be elected with
  affirmative majority of votes cast, provided that the resolutions allow for
  plurality voting in cases of contested elections.

                                       94


TAKEOVER-RELATED MEASURES
Pioneer is generally opposed to proposals that may discourage takeover
attempts. We believe that the potential for a takeover helps ensure that
corporate performance remains high.

Pioneer will vote for:

o Cumulative voting.

o Increasing the ability for shareholders to call special meetings.

o Increasing the ability for shareholders to act by written consent.

o Restrictions on the ability to make greenmail payments.

o Submitting rights plans to shareholder vote.

o Rescinding shareholder rights plans ("poison pills").

o Opting out of the following state takeover statutes:

  - Control share acquisition statutes, which deny large holders voting rights
    on holdings over a specified threshold.

  - Control share cash-out provisions, which require large holders to acquire
    shares from other holders

  - Freeze-out provisions, which impose a waiting period on large holders
    before they can attempt to gain control

  - Stakeholder laws, which permit directors to consider interests of
    non-shareholder constituencies.

  - Disgorgement provisions, which require acquirers to disgorge profits on
    purchases made before gaining control.

  - Fair price provisions.

  - Authorization of shareholder rights plans.

  - Labor protection provisions.

  - Mandatory classified boards.

We will vote on a case-by-case basis on the following issues:

o Fair price provisions. We will vote against provisions requiring
  supermajority votes to approve takeovers. We will also consider voting
  against proposals that require a supermajority vote to repeal or amend the
  provision. Finally, we will consider the mechanism used to determine the
  fair price; we are generally opposed to complicated formulas or requirements
  to pay a premium.

o Opting out of state takeover statutes regarding fair price provisions. We
  will use the criteria used for fair price provisions in general to determine
  our vote on this issue.

o Proposals that allow shareholders to nominate directors.

We will vote against:

o Classified boards, except in the case of closed-end funds, where we shall
  vote on a case-by-case basis.

o Limiting shareholder ability to remove or appoint directors. We will support
  proposals to restore shareholder authority in this area. We will review on
  case-by-case basis proposals that authorize the board to make interim
  appointments.

o Classes of shares with unequal voting rights.

o Supermajority vote requirements.

o Severance packages ("golden" and "tin" parachutes). We will support proposals
  to put these packages to shareholder vote.

o Reimbursement of dissident proxy solicitation expenses. While we ordinarily
  support measures that encourage takeover bids, we believe that management
  should have full control over corporate funds.

                                       95


o Extension of advance notice requirements for shareholder proposals.

o Granting board authority normally retained by shareholders (e.g., amend
  charter, set board size).

o Shareholder rights plans ("poison pills"). These plans generally allow
  shareholders to buy additional shares at a below-market price in the event
  of a change in control and may deter some bids.


CAPITAL STRUCTURE
Managements need considerable flexibility in determining the company's
financial structure, and Pioneer normally supports managements' proposals in
this area. We will, however, reject proposals that impose high barriers to
potential takeovers.

Pioneer will vote for:

o Changes in par value.

o Reverse splits, if accompanied by a reduction in number of shares.

o Shares repurchase programs, if all shareholders may participate on equal
  terms.

o Bond issuance.

o Increases in "ordinary" preferred stock.

o Proposals to have blank check common stock placements (other than shares
  issued in the normal course of business) submitted for shareholder approval.

o Cancellation of company treasury shares.

We will vote on a case-by-case basis on the following issues:

o Reverse splits not accompanied by a reduction in number of shares,
  considering the risk of delisting.

o Increase in authorized common stock. We will make a determination
  considering, among other factors:

  - Number of shares currently available for issuance;

  - Size of requested increase (we would normally approve increases of up to
    100% of current authorization);

  - Proposed use of the proceeds from the issuance of additional shares, and

  - Potential consequences of a failure to increase the number of shares
    outstanding (e.g., delisting or bankruptcy).

o Blank check preferred. We will normally oppose issuance of a new class of
  blank check preferred, but may approve an increase in a class already
  outstanding if the company has demonstrated that it uses this flexibility
  appropriately.

o Proposals to submit private placements to shareholder vote.

o Other financing plans.

We will vote against preemptive rights that we believe limit a company's
 financing flexibility.


COMPENSATION
Pioneer supports compensation plans that link pay to shareholder returns and
believes that management has the best understanding of the level of
compensation needed to attract and retain qualified people. At the same time,
stock-related compensation plans have a significant economic impact and a
direct effect on the balance sheet. Therefore, while we do not want to
micromanage a company's compensation programs, we will place limits on the
potential dilution these plans may impose.

Pioneer will vote for:

o 401(k) benefit plans.

                                       96


o Employee stock ownership plans (ESOPs), as long as shares allocated to ESOPs
  are less than 5% of outstanding shares. Larger blocks of stock in ESOPs can
  serve as a takeover defense. We will support proposals to submit ESOPs to
  shareholder vote.

o Various issues related to the Omnibus Budget and Reconciliation Act of 1993
  (OBRA), including:

  - Amendments to performance plans to conform with OBRA;

  - Caps on annual grants or amendments of administrative features;

  - Adding performance goals, and

  - Cash or cash and stock bonus plans.

o Establish a process to link pay, including stock-option grants, to
  performance, leaving specifics of implementation to the company.

o Require that option repricing be submitted to shareholders.

o Require the expensing of stock-option awards.

o Require reporting of executive retirement benefits (deferred compensation,
  split-dollar life insurance, SERPs, and pension benefits).

o Employee stock purchase plans where the purchase price is equal to at least
  85% of the market price, where the offering period is no greater than 27
  months and where potential dilution (as defined below) is no greater than
  10%.

We will vote on a case-by-case basis on the following issues:

o Shareholder proposals seeking additional disclosure of executive and director
  pay information.

o Executive and director stock-related compensation plans. We will consider the
  following factors when reviewing these plans:

  - The program must be of a reasonable size. We will approve plans where the
    combined employee and director plans together would generate less than 15%
    dilution. We will reject plans with 15% or more potential dilution.

                        Dilution = (A + B + C) / (A + B + C + D), where
                        A = Shares reserved for plan/amendment,
                        B = Shares available under continuing plans,
                        C = Shares granted but unexercised and
                        D = Shares outstanding.

  - The plan must not:

    - Explicitly permit unlimited option repricing authority or that have
      repriced in the past without shareholder approval

    - Be a self-replenishing "evergreen" plan, or a plan that grants discount
      options and tax offset payments

  - We are generally in favor of proposals that increase participation beyond
    executives.

  - We generally support proposals asking companies to adopt rigorous vesting
    provisions for stock option plans such as those that vest incrementally
    over, at least, a three- or four-year period with a pro rata portion of
    the shares becoming exercisable on an annual basis following grant date.

  - We generally support proposals asking companies to disclose their window
    period policies for stock transactions. Window period policies ensure that
    employees do not exercise options based on insider information
    contemporaneous with quarterly earnings releases and other material
    corporate announcements.

  - We generally support proposals asking companies to adopt stock holding
    periods for their executives.

o All other employee stock purchase plans.

                                       97


o All other compensation-related proposals, including deferred compensation
  plans, employment agreements, loan guarantee programs and retirement plans.

o All other proposals regarding stock compensation plans, including extending
  the life of a plan, changing vesting restrictions, repricing options,
  lengthening exercise periods or accelerating distribution of awards and
  pyramiding and cashless exercise programs.

We will vote against:

o Pensions for non-employee directors. We believe these retirement plans reduce
  director objectivity.

o Elimination of stock option plans.

We will vote on a case-by-case basis on these issues:

o Limits on executive and director pay.

o Stock in lieu of cash compensation for directors.


CORPORATE GOVERNANCE
Pioneer will vote for:

o Confidential voting.

o Equal access provisions, which allow shareholders to contribute their
  opinions to proxy materials.

o Proposals requiring directors to disclose their ownership of shares in the
  company.

We will vote on a case-by-case basis on the following issues:

o Change in the state of incorporation. We will support reincorporations
  supported by valid business reasons. We will oppose those that appear to be
  solely for the purpose of strengthening takeover defenses.

o Bundled proposals. We will evaluate the overall impact of the proposal.

o Adopting or amending the charter, bylaws or articles of association.

o Shareholder appraisal rights, which allow shareholders to demand judicial
  review of an acquisition price.

We will vote against:

o Shareholder advisory committees. While management should solicit shareholder
  input, we prefer to leave the method of doing so to management's discretion.

o Limitations on stock ownership or voting rights.

o Reduction in share ownership disclosure guidelines.

                                       98


MERGERS AND RESTRUCTURINGS
Pioneer will vote on the following and similar issues on a case-by-case basis:

o Mergers and acquisitions.

o Corporate restructurings, including spin-offs, liquidations, asset sales,
  joint ventures, conversions to holding company and conversions to
  self-managed REIT structure.

o Debt restructurings.

o Conversion of securities.

o Issuance of shares to facilitate a merger.

o Private placements, warrants, convertible debentures.

o Proposals requiring management to inform shareholders of merger
  opportunities.

We will normally vote against shareholder proposals requiring that the company
 be put up for sale.


MUTUAL FUNDS
Many of our portfolios may invest in shares of closed-end funds or
exchange-traded funds. The non-corporate structure of these investments raises
several unique proxy-voting issues.

Pioneer will vote for:

o Establishment of new classes or series of shares.

o Establishment of a master-feeder structure.

Pioneer will vote on a case-by-case on:

o Changes in investment policy. We will normally support changes that do not
  affect the investment objective or overall risk level of the fund. We will
     examine more fundamental changes on a case-by-case basis.

o Approval of new or amended advisory contracts.

o Changes from closed-end to open-end format.

o Election of a greater number of independent directors (in order to move
  closer to a majority of independent directors) in cases of poor performance.

o Authorization for, or increase in, preferred shares.

o Disposition of assets, termination, liquidation, or mergers.

o Classified boards of closed-end funds, but will typically support such
  proposals.


SOCIAL ISSUES
Pioneer will abstain on stockholder proposals calling for greater disclosure of
corporate activities with regard to social issues. "Social Issues" may
generally be described as shareholder proposals for a company to:

o Conduct studies regarding certain issues of public concern and interest;

o Study the feasibility of the company taking certain actions with regard to
  such issues; or

o Take specific action, including ceasing certain behavior and adopting company
  standards and principles, in relation to issues of public concern and
  interest.

We believe these issues are important and should receive management attention.

Pioneer will vote against proposals calling for substantial changes in the
company's business or activities. We will also normally vote against proposals
with regard to contributions, believing that management should control the
routine disbursement of funds.

                                       99


AVOIDING CONFLICTS OF INTEREST
Pioneer recognizes that in certain circumstances a conflict of interest may
arise when Pioneer votes a proxy.

A conflict of interest occurs when Pioneer's interests interfere, or appear to
interfere with the interests of Pioneer's clients.

A conflict may be actual or perceived and may exist, for example, when the
matter to be voted on concerns:

o An affiliate of Pioneer, such as another company belonging to the UniCredit
  S.p.A. banking group (a "UniCredit Affiliate");

o An issuer of a security for which Pioneer acts as a sponsor, advisor,
  manager, custodian, distributor, underwriter, broker, or other similar
  capacity (including those securities specifically declared by PGAM to
  present a conflict of interest for Pioneer);

o An issuer of a security for which UniCredit has informed Pioneer that a
  UniCredit Affiliate acts as a sponsor, advisor, manager, custodian,
  distributor, underwriter, broker, or other similar capacity; or

o A person with whom Pioneer (or any of its affiliates) has an existing,
  material contract or business relationship.

Any member of the Proxy Voting Oversight Group and any other associate involved
in the proxy voting process with knowledge of any apparent or actual conflict
of interest must disclose such conflict to the Proxy Coordinator and the Chief
Compliance Officer of Pioneer and the Funds. If any associate is lobbied or
pressured with respect to any voting decision, whether within or outside of
Pioneer, he or she should contact a member of the Proxy Voting Oversight Group
or Pioneer's Chief Compliance Officer.

The Proxy Voting Oversight Group will review each item referred to Pioneer by
the proxy voting service to determine whether an actual or potential conflict
of interest exists in connection with the proposal(s) to be voted upon. The
review will be conducted by comparing the apparent parties affected by the
proxy proposal being voted upon against the Controller's and Compliance
Department's internal list of interested persons and, for any matches found,
evaluating the anticipated magnitude and possible probability of any conflict
of interest being present. The Proxy Voting Oversight Group may cause any of
the following actions to be taken when a conflict of interest is present:

o Vote the proxy in accordance with the vote indicated under "Voting
  Guidelines," If a vote is indicated;

o Direct the independent proxy voting service to vote the proxy in accordance
  with its independent assessment; or

o As determined by the Proxy Voting Oversight Group in its discretion
  consistent with its fiduciary duty.

If the Proxy Voting Oversight Group perceives a material conflict of interest,
the group may also choose to disclose the conflict to the affected clients and
solicit their consent to proceed with the vote, or may take such other action
in good faith (in consultation with counsel) that would protect the interest of
clients.

For each referral item, the determination regarding the presence or absence of
any actual or potential conflict of interest will be documented in a Conflicts
of Interest Report prepared by the Proxy Coordinator.

The Proxy Voting Oversight Group will review periodically the independence of
the proxy voting service. This may include a review of the service's conflict
management procedures and other documentation, and an evaluation as to whether
the service continues to have the competency and capacity to vote proxies.


DECISION NOT TO VOTE PROXIES
Although it is Pioneer's general policy to vote all proxies in accordance with
the principles set forth in this policy, there may be situations in which the
Proxy Voting Oversight Group does not vote a proxy referred to it. For example,
because of the potential conflict of interest inherent in voting shares of a
UniCredit


                                      100


affiliate, Pioneer will abstain from voting the shares unless otherwise
directed by a client. In such a case, the Proxy Coordinator will inform PGAM
Global Compliance and the PGAM Independent Directors before exercising voting
rights.

There exist other situations in which the Proxy Voting Oversight Group may
refrain from voting a proxy. For example, if the cost of voting a foreign
security outweighs the benefit of voting, the Group may not vote the proxy. The
Group may not be given enough time to process a vote, perhaps because it
receives a meeting notice too late or it cannot obtain a translation of the
agenda in the time available. If Pioneer has outstanding "sell" orders, the
proxies for shares subject to the order may not be voted to facilitate the
sale. Although Pioneer may hold shares on a company's record date, if the
shares are sold prior to the meeting date, the Group may decide not to vote
those shares.
