To the Shareholders of Pioneer Solutions - Conservative Fund and Pioneer
Solutions - Growth Fund:

     The Board of Trustees of Pioneer Solutions - Conservative Fund and
Pioneer Solutions - Growth Fund has approved the reorganization of each fund
(each, an "Acquired Fund") with and into Pioneer Solutions - Balanced Fund
(the "Acquiring Fund") after considering the recommendation of Amundi Pioneer
Asset Management, Inc. ("Amundi Pioneer"), the investment manager to your fund,
and concluding that the reorganization would be in the best interests of your
fund.

     Following is a brief description of certain aspects of the reorganizations:

     o    Each fund has the same investment objective of long-term capital
          growth and current income.

     o    Each fund has similar investment policies and strategies. Like the
          Acquired Funds, the Acquiring Fund is a "fund of funds" that allocates
          its assets primarily among other mutual funds, including mutual funds
          managed by Amundi Pioneer and funds unaffiliated with Amundi Pioneer
          ("underlying funds"). Following the completion of the reorganizations,
          it is anticipated that the combined fund will invest to a greater
          extent in underlying funds managed by Amundi Pioneer. In addition,
          unlike the Acquired Funds, it is expected that, following the
          completion of the reorganizations, Amundi Pioneer will not seek to
          maintain a target annualized volatility level for the combined fund or
          use derivative strategies to a significant extent to seek incremental
          return or to seek to limit risk.

     o    The expense ratio of each class of shares of the combined fund is
          expected to be no higher than the expense ratio of the corresponding
          class of shares of your fund.

     o    Unlike the Acquired Funds and the Acquiring Fund, the combined fund
          will not pay a direct management fee to Amundi Pioneer. However, as is
          currently the case for each of the funds, following the completion of
          the Reorganizations, the combined fund will continue to bear a pro
          rata portion of the fees and expenses, including management fees, of
          each underlying fund in which the combined fund invests.

     o    None of the funds has achieved a sufficient size to allow for more
          efficient operations. The larger asset size of the combined fund may
          allow it, relative to your fund, to reduce per share expenses as fixed
          expenses will be shared over a larger asset base.

     o    Upon completion of the reorganization of your fund, you will hold
          shares of each class of the Acquiring Fund corresponding to a class of
          your fund's shares that you hold immediately prior to the
          reorganization having the same aggregate net asset value as your
          holdings of shares of that class of your fund immediately prior to the
          reorganization.

     o    Each transaction is expected to be treated as a "reorganization" under
          Section 368(a) of the Internal Revenue Code of 1986, as amended, and
          shareholders therefore are not expected to recognize any taxable gain
          or loss on the exchange of their Acquired Fund shares for shares of
          the Acquiring Fund.

     Each reorganization is expected to occur on or about January 19, 2018.
Although the reorganizations may be viewed as separate transactions, and
neither reorganization is contingent on the occurrence of the other
reorganization, the reorganizations are expected to occur simultaneously. No
commission, redemption fee or other transactional fee will be charged as a
result of the reorganizations.

     The reorganizations do not require shareholder approval, and you are not
being asked to vote. We do, however, ask that you review the enclosed
information statement/prospectus, which contains information about the combined
fund, outlines the differences between each Acquired Fund and the combined
fund, and provides details about the terms and conditions of each
reorganization.

     The Board of Trustees of each Acquired Fund has unanimously approved each
Acquired Fund's reorganization and believes each reorganization is in the best
interests of your fund.

     If you have any questions, please call 1-800-225-6292.

                              Sincerely,

Background to the Reorganization

     Amundi Pioneer Asset Management, Inc. ("Amundi Pioneer"), each fund's
investment adviser, has recommended the reorganization of each Acquired Fund
with the Acquiring Fund (each, a "Reorganization"), and the Board of Trustees
has determined that the Reorganization of each Acquired Fund is in the best
interests of such Acquired Fund. Factors that Amundi Pioneer took into
consideration in making its recommendations, and the Board of Trustees took
into consideration in making its determinations, include:

     o    The expense ratio of each class of shares of the combined fund is
          expected to be no higher than the expense ratio of the corresponding
          class of shares of your fund.

     o    Unlike the Acquired Funds and the Acquiring Fund, the combined fund
          will not pay a direct management fee to Amundi Pioneer. However, as is
          currently the case for each of the funds, following the completion of
          the Reorganizations, the combined fund will continue to bear a pro
          rata portion of the fees and expenses, including management fees, of
          each underlying fund in which the combined fund invests. The pro rata
          portion of the management fees of underlying Amundi Pioneer funds
          borne by the combined fund following the completion of the
          Reorganizations is not expected to exceed the direct management fee
          and the pro rata portion of the management fees of underlying Amundi
          Pioneer funds currently borne by your fund.

     o    None of the funds has achieved a sufficient size to allow for more
          efficient operations. The larger asset size of the combined fund may
          allow it, relative to your fund, to reduce per share expenses as fixed
          expenses will be shared over a larger asset base.

                                       3



     o    Each fund has the same investment objective of long-term capital
          growth and current income.

     o    Each fund has similar investment policies and strategies. Like the
          Acquired Funds, the Acquiring Fund is a "fund of funds" that allocates
          its assets primarily among other mutual funds, including mutual funds
          managed by Amundi Pioneer and funds unaffiliated with Amundi Pioneer
          ("underlying funds"). Following the completion of the Reorganizations,
          it is anticipated that the combined fund will invest to a greater
          extent in underlying funds managed by Amundi Pioneer. In addition,
          unlike the Acquired Funds and the Acquiring Fund, it is expected that,
          following the completion of the Reorganizations, Amundi Pioneer will
          not seek to maintain a target annualized volatility level for the
          combined fund or use derivative strategies to a significant extent to
          seek incremental return or to seek to limit risk.

     o    Each Reorganization, itself, generally is not expected to result in
          income, gain or loss being recognized for federal income tax purposes
          by the Acquired Fund, the Acquiring Fund or by the shareholders of any
          fund.

     At a meeting held on September 12, 2017, the Board of Trustees of the
funds unanimously approved the Reorganization of each Acquired Fund with the
Acquiring Fund. The Reorganization of each Acquired Fund is not subject to
approval by the shareholders of such Acquired Fund.

How will the Reorganizations work?

     o    Each Acquired Fund's Reorganization is scheduled to occur on or about
          January 19, 2018, but may occur on such later date as the parties may
          agree in writing (the "Closing Date").

     o    Your fund will transfer all of its assets to the Acquiring Fund, and
          the Acquiring Fund will assume all of your fund's liabilities.

     o    The Acquiring Fund will issue Class A, Class C, Class R and Class Y
          shares to your fund with an aggregate net asset value equal to the
          aggregate net asset value of your fund's Class A, Class C, Class R and
          Class Y shares, respectively.

     o    Shares of the Acquiring Fund will be distributed to you on a
          class-by-class basis in proportion to the relative net asset value of
          your holdings of shares of each class of your fund on the Closing
          Date. Therefore, upon completion of the Reorganization, you will hold
          shares of each class of the Acquiring Fund corresponding to a class of
          your fund held by you with the same aggregate net asset value as your
          holdings of shares of that class of your fund immediately prior to the
          Reorganization. The net asset value attributable to a class of shares
          of each fund will be determined using the Pioneer Funds' valuation
          policies and procedures. Each fund's valuation policy and procedures
          are identical.

     o    No sales load, contingent deferred sales charge, commission,
          redemption fee or other transactional fee will be charged as a result
          of the Reorganizations. After the Reorganizations, any contingent
          deferred sales charge that applied to your Class A or Class C shares
          of your fund at the time of the Reorganizations will continue to apply
          for the remainder of the applicable holding period at the time of the
          Reorganizations. In calculating any applicable contingent deferred
          sales charge, the period during which you held your shares will be
          included in the holding period of the shares you receive as a result
          of the Reorganizations.

     o    The Reorganizations generally are not expected to result in gain or
          loss being recognized for federal income tax purposes by any fund or
          by the shareholders of any fund.

     o    In approving the Reorganization of each Acquired Fund, the Board of
          Trustees of each fund, including all of the Trustees who are not
          "interested" persons (as defined in the Investment Company Act of
          1940, as amended (the "1940 Act")) of the Pioneer Funds, Amundi
          Pioneer, or Amundi Pioneer Distributor, Inc., the Pioneer Funds'
          principal underwriter and distributor ("Amundi Pioneer Distributor")
          (the "Independent Trustees"), has determined that such Reorganization
          is in the best interest of such Acquired Fund and the Acquiring Fund
          and will not dilute the interests of shareholders. The Trustees have
          made this determination based on factors that are discussed below.

     o    Shareholders of an Acquired Fund who determine that they do not wish
          to become shareholders of the combined fund may (a) redeem their
          shares of their Acquired Fund prior to the Closing Date or (b)
          exchange their shares of their Acquired Fund prior to the Closing Date
          for shares of another Pioneer fund by contacting Amundi Pioneer or
          their investment professional or financial intermediary. Any
          contingent deferred sales charge that applies to your Class A or Class
          C shares will be waived in connection with a redemption of your shares
          of an Acquired Fund prior to the Closing Date. Please note that a
          redemption or an exchange of shares of an Acquired Fund will be a
          taxable event and a shareholder may recognize a gain or loss for
          federal income tax purposes in connection with that transaction.

     This Information Statement/Prospectus relates only to the Class A, Class
C, Class R and Class Y shares to be issued in the Reorganization.

What are the federal income tax consequences of each Reorganization?

     As a condition to the closing of each Reorganization, the applicable
Acquired Fund and the Acquiring Fund must receive an opinion of Morgan, Lewis &
Bockius LLP substantially to the effect that the Reorganization will constitute
a "reorganization" within the meaning of Section 368(a) of the Internal Revenue
Code of 1986, as amended (the "Internal Revenue Code"). Accordingly, subject to
the limited exceptions described below under the heading "Tax Status of the
Reorganizations," it is expected that neither you nor in general your Acquired
Fund will recognize gain or loss as a direct result of the applicable
Reorganization, and that the aggregate tax basis of the shares of each class
that you receive in that Reorganization will be the same as the aggregate tax
basis of the shares of the corresponding class that you surrender in that
Reorganization. In addition, your holding period for the shares of each class
you receive in the applicable Reorganization will include the holding period of
the shares of the corresponding class that you surrender in that
Reorganization, provided that you held those shares as capital assets on the
date of that Reorganization. However, in accordance with the Pioneer Funds'
policy that each Pioneer Fund distributes its investment company taxable income
(computed without regard to the dividends-paid deduction), net tax-exempt
income and net capital gains for each taxable year (in order to qualify for tax
treatment as a regulated investment company and avoid federal income and excise
tax thereon at the fund level), your Acquired Fund will declare and pay a
distribution of such income and gains to its shareholders shortly before the
applicable Reorganization. Such distribution may affect the amount, timing or
character of taxable income that you realize in respect of your Acquired Fund
shares. For more information, see "Tax Status of the Reorganizations" on page
42 of the Information Statement/Prospectus. The Acquiring Fund may make a
comparable distribution to its shareholders shortly before one or both
Reorganizations. Additionally, following the Reorganizations, the Acquiring
Fund will continue to make distributions according to its regular distribution
schedule. You will generally need to pay tax on those distributions even though
they may include income and gains that were accrued and/or realized before you
became a shareholder of the Acquiring Fund.

Who bears the expenses associated with the Reorganization?

     Each Acquired Fund agrees to pay 25% of the expenses incurred in
connection with the Reorganization of such Acquired Fund, including expenses
associated with preparation, printing and mailing of any shareholder
communications (including this Information Statement/Prospectus), any filings
with the SEC and other governmental agencies in connection with the
Reorganization, audit fees and legal fees ("Reorganization Costs"). The
Acquiring Fund agrees to pay 25% of the Reorganization Costs incurred in
connection with each Reorganization. Amundi Pioneer will bear the remaining 50%
of the Reorganization Costs. If both Reorganizations are consummated on the
same Closing Date, 12.5% of the aggregate Reorganization Costs shall be paid by
each Acquired Fund, and 25% of the aggregate Reorganization Costs shall by paid
by the Acquiring Fund. Amundi Pioneer would bear the remaining 50% of the
Reorganization Costs. It is estimated that these expenses in the aggregate will
be approximately $150,000, of which each Acquired Fund will bear approximately
$18,750 for its Reorganization, the Acquiring Fund will bear approximately
$37,500 in the aggregate for both Reorganizations, and Amundi Pioneer will bear
the remaining $75,000. If only one Acquired Fund's Reorganization is
consummated, such Acquired Fund will bear approximately $37,500 of the
Reorganization Costs and the Acquiring Fund will bear approximately $37,500 of
the Reorganization Costs. Amundi Pioneer would bear the remaining 50% of the
Reorganization Costs. Expenses will, however, be paid by the party directly
incurring the expenses to the extent that the payment by another person would
result in a failure by any fund to qualify for treatment as a "regulated
investment company" within the meaning of Section 851 of the Internal Revenue
Code or would prevent a Reorganization from qualifying as a "reorganization"
within the meaning of Section 368 of the Internal Revenue Code or otherwise
result in the imposition of tax on a fund or on a fund's shareholders.

         REORGANIZATIONS OF PIONEER SOLUTIONS - CONSERVATIVE FUND AND
                     PIONEER SOLUTIONS - GROWTH FUND WITH
                       PIONEER SOLUTIONS - BALANCED FUND

                                    SUMMARY

     The following is a summary of more complete information appearing later in
this Information Statement/Prospectus or incorporated herein. You should read
carefully the entire Information Statement/Prospectus, including the form of
Agreement and Plan of Reorganization attached as Exhibit A, because it contains
details that are not in the summary.

                                Fund Comparison

     The Board of Trustees of each Acquired Fund has approved the
Reorganization of each Acquired Fund with the Acquiring Fund. There are
similarities among the funds, as well as certain differences, including:

     o    Investment Adviser. Each fund currently is managed by Amundi Pioneer.
          Following the completion of the Reorganizations, the combined fund
          will be managed by Amundi Pioneer. The funds' portfolio management
          team currently consists of John O'Toole, Paul Weber, and Salvatore
          Buono. Following the completion of the Reorganizations, the combined
          fund's management team will consist of Kenneth J. Taubes and Marco
          Pirondini.

     o    Investment Objective. Each fund currently has the same investment
          objective of long-term capital growth and current income. Following
          the completion of the Reorganizations, the investment objective of the
          combined fund also will be long-term capital growth.

     o    "Fund of Funds." Each fund currently is a "fund of funds." Following
          the completion of the Reorganizations, the combined fund will remain a
          "fund of funds."

     o    Focus on Underlying Pioneer Funds. Each fund currently allocates
          approximately 60%-70% of its total assets to underlying funds managed
          by Amundi Pioneer. Following the completion of the Reorganizations, it
          is anticipated that, initially, the combined fund will invest to a
          greater extent (90%-95% of its total assets) in underlying funds
          managed by Amundi Pioneer.

     o    Investment Process. For each fund, Amundi Pioneer currently selects
          investments it believes will perform well over time while maintaining
          a target annualized volatility level that corresponds to the fund's
          relative risk profile. Following the completion of the
          Reorganizations, Amundi Pioneer will not seek to maintain a target
          annualized volatility level for the combined fund, but the portfolio
          management team will continue to evaluate asset classes, fund
          attributes, broad economic and market factors, and strategic and
          tactical considerations in its investment decisions. In addition, each
          fund currently uses derivative strategies to seek incremental return
          or to seek to limit risk. Following the completion of the
          Reorganizations, the combined fund will continue to have the ability
          to use derivatives, but it is currently anticipated that the combined
          fund generally will not use derivative strategies to the same extent
          as does your fund.

     o    Asset Class Exposure. Following the completion of the Reorganizations,
          it is anticipated that, initially, the combined fund's exposure to
          different asset classes will most closely resemble the Acquiring
          Fund's exposure to different asset classes prior to the
          Reorganizations. At July 31, 2017, approximately 42% of the Balanced
          Fund's total assets was invested in fixed income underlying funds,
          approximately 35% of the fund's total assets was invested in
          international equity underlying funds, approximately 18% of the fund's
          total assets was invested in U.S. equity funds, and approximately 4%
          of the fund's total assets was invested directly in fixed income
          obligations. Accordingly, it is anticipated that, following the
          completion of the Reorganizations, the combined fund will have: (i)
          relative to Pioneer Solutions - Conservative Fund, significantly less
          exposure to fixed income investments and their related risks and
          significantly more exposure to international and U.S. equity
          investments and their related risks; and (ii) relative to Pioneer
          Solutions - Growth Fund, significantly more exposure to fixed income
          investments and their related risks and significantly less exposure to
          international and U.S. equity investments and their related risks.
          However, the combined fund's exposure to different asset classes and
          allocations among underlying funds will change from time to time in
          response to broad economic and market factors, as well as strategic
          and tactical considerations. There is no maximum or minimum exposure
          that the fund must have to any asset class.

                                       6



     The tables below compare certain features of each fund to the features of
the combined fund that will be in effect upon completion of the
Reorganizations. In the table below, if a row extends across the entire table,
the policy disclosed applies to both your fund and the combined fund.



                                                                                                    Pioneer Solutions -

Investment Long-term capital growth and current income.
Objective
-----------------------------------------------------------------------------------------------------------------------------------
           The fund's investment objective may be changed without shareholder approval. The fund will provide at least 30 days'
           notice prior to implementing any change to its investment objective.
-----------------------------------------------------------------------------------------------------------------------------------
Principal  The fund seeks to achieve its investment objectives by primarily investing in other funds ("underlying funds") and
Investment using asset allocation strategies to allocate its assets among the underlying funds.

Conservative Fund            Growth Fund                  Balanced Fund                        Post-Reorganization)
-------------------------------------------------------------------------------------------------------------------------------
                                                                                      
The fund may also invest in securities of unaffiliated mutual funds or exchange-traded funds ("ETFs") when the desired
economic exposure to a particular asset category or investment strategy is not available through a Pioneer fund.
-------------------------------------------------------------------------------------------------------------------------------
The fund allocates its assets among underlying funds with exposure to the broad asset classes of equity, fixed income and
short-term (money market) investments. The fund also may invest in underlying funds with exposure to non-traditional --
so-called "alternative" -- asset classes such as real estate investment trusts ("REITs") or commodities, or that use
alternative strategies, such as market neutral strategies (strategies that seek to achieve positive returns while attempting to
limit general market exposure) or relative value strategies (strategies that seek to identify securities that are undervalued
relative to each other or historical norms).
-------------------------------------------------------------------------------------------------------------------------------
The fund does not have target ranges for the allocation of assets among asset classes or individual underlying funds.
Accordingly, the fund's exposure to different asset classes and allocations among underlying funds will change from time to
time in response to broad economic and market factors, as well as strategic and tactical considerations. There is no
maximum or minimum exposure that the fund must have to any asset class. The equity securities to which the fund may
have exposure may be of any market capitalization. The fixed income securities to which the fund may have exposure may
be of any maturity and of any credit quality, including high yield or "junk" bonds.

Due to market conditions and other factors, the actual or realized volatility of the fund for
any particular period of time may be materially higher or lower than the target level. The
fund's volatility results from rapid and dramatic price swings of securities held by the
underlying funds in which the fund invests. Higher volatility generally indicates higher risk.

Amundi Pioneer allocates the fund's assets among underlying funds and other investments based on strategic positioning
and tactical considerations, taking into account both broad economic and market factors and factors specific to particular
investments. Amundi Pioneer allocates the fund's investments in the underlying funds based on an evaluation of three
components: strategic asset allocation (generally, the weighting of allocations among broad asset classes to capture market
returns), tactical asset allocation (generally, the weighting of allocations to various sub-categories within broad asset
classes to add value relative to the general strategic allocations) and fund selection. Amundi Pioneer's analysis in selecting
underlying funds includes an assessment of the fund's historical relative and absolute performance, volatility and other risk
characteristics, and correlation with other funds and benchmarks. Amundi Pioneer considers the relative return potential of
investments in view of their expected relative risk, including potential volatility and drawdown risk (the risk of significant
loss, measured from peak value) among other risks. Amundi Pioneer also analyzes the fund's investment strategies,
investment process and portfolio management team. The goal of this process is to identify a combination of investments
with the potential to provide total return consistent with the fund's overall risk/return profile.

Portfolio  The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio).
Turnover   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.

            grade if it is rated in one of the top four categories by a nationally recognized statistical rating organization or
            determined to be of equivalent credit quality by the adviser.
------------------------------------------------------------------------------------------------------------------------------------
U.S.        The fund may invest in U.S. government securities. U.S. government securities are obligations of, or guaranteed by, the
Government  U.S. government, its agencies or government-sponsored entities. U.S. government securities include obligations: directly
Securities  issued by or supported by the full faith and credit of the U.S. government, like Treasury bills, notes and bonds and
            Government National Mortgage Association ("GNMA") certificates; supported by the right of the issuer to borrow from the
            U.S. Treasury, like those of the Federal Home Loan Banks ("FHLBs"); supported by the discretionary authority of the U.S.
            government to purchase the agency's securities like those of the Federal National Mortgage Association ("FNMA"); or
            supported only by the credit of the issuer itself, like the Tennessee Valley Authority. U.S. government securities
            include issues by non-governmental entities (like financial institutions) that carry direct guarantees from U.S.
            government agencies as part of government initiatives in response to the market crisis or otherwise. U.S. government
            securities include zero coupon securities that make payments of interest and principal only upon maturity and which
            therefore tend to be subject to greater volatility than interest bearing securities with comparable maturities.

            Although the U.S. government guarantees principal and interest payments on securities issued by the U.S. government and
            some of its agencies, such as securities issued by GNMA, this guarantee does not apply to losses resulting from
            declines in the market value of these securities. Some of the U.S. government securities that the fund may hold are not
            guaranteed or backed by the full faith and credit of the U.S. government, such as those issued by FNMA and Federal Home
            Loan Mortgage Corporation ("FHLMC").
------------------------------------------------------------------------------------------------------------------------------------
Mortgage-   The fund may invest in mortgage-backed securities. Mortgage-backed securities may be issued by private issuers, by
Backed      government-sponsored entities such as FNMA or FHLMC or by agencies of the U.S. government, such as GNMA.
Securities  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.

------------------------------------------------------------------------------------------------------------------------------------
                                                                            
Asset-Backed The fund may invest in asset-backed securities. Asset-backed securities represent participations in, or are secured by
Securities   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.
------------------------------------------------------------------------------------------------------------------------------------
Event-Linked The fund may invest in "event-linked" bonds, which sometimes are referred to as "insurance-linked" or "catastrophe"
Bond and     bonds. Event-linked bonds are debt obligations for which the return of principal and the payment of interest are
other        contingent on the non-occurrence of a pre-defined "trigger" event, such as a hurricane or an earthquake of a specific
Insurance-   magnitude or other event that leads to physical or economic loss. For some event-linked bonds, the trigger event's
Linked       magnitude may be based on losses to a company or industry, industry indexes or readings of scientific instruments
Securities   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 below investment grade or 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, which will
             cause a loss of principal. This rating may also assess the credit risk of the bond's collateral pool, if any, and the
             reliability of 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.
------------------------------------------------------------------------------------------------------------------------------------
Floating     Floating rate investments are securities and other instruments with interest rates that adjust or "float" periodically
Rate         based on a specified interest rate or other reference and include floating rate loans, repurchase agreements, money
Investments  market securities and shares of money market and short-term bond funds.

             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. The rates of interest on the loans typically adjust periodically by reference to a base lending rate,
             such as the London Interbank Offered Rate ("LIBOR"), a designated U.S. bank's prime or base rate or the overnight
             federal funds rate, plus a premium. Some loans reset on set dates, typically every 30 to 90 days, but not to exceed one
             year. Other loans reset periodically when the underlying rate resets.

             In most instances, the fund's investments in floating rate loans hold a senior position in the capital structure of the
             borrower. Having a senior position means that, if the borrower becomes insolvent, senior debtholders, like the fund,
             will be paid before subordinated debtholders and stockholders of the borrower. Senior loans typically are secured by
             specific collateral.

             Floating rate loans typically are structured and administered by a financial institution that acts as an agent for the
             holders of the loan. Loans can be acquired directly through the agent, by assignment from another holder of the loan,
             or as a participation interest in the loan. When the fund is a direct investor in a loan, the fund may have the ability
             to influence the terms of the loan, although the fund does not act as the sole negotiator or originator of the loan.
             Participation interests are fractional interests in a loan issued by a lender or other financial institution. When the
             fund invests in a loan participation, the fund does not have a direct claim against the borrower and must rely upon an
             intermediate participant to enforce any rights against the borrower.

Subordinated   The fund may invest in securities that are subordinated or "junior" to more senior securities of the issuer. The
Securities     investor in a subordinated security of an issuer is entitled to payment after other holders of debt in that issuer.
------------------------------------------------------------------------------------------------------------------------------------
Investment     A debt security is considered investment grade if it is:
Grade          -- Rated BBB or higher at the time of purchase by Standard & Poor's Financial Services LLC;
Securities     -- Rated the equivalent rating by a nationally recognized statistical rating organization; or
               -- Determined to be of equivalent credit quality by Amundi Pioneer

               Securities in the lowest category of investment grade (i.e., BBB) are considered to have speculative characteristics.
               An investor can still lose significant amounts when investing in investment grade securities.
------------------------------------------------------------------------------------------------------------------------------------
Below          The fund may invest in debt securities rated below investment grade or, if unrated, of equivalent quality as
Investment     determined by Amundi Pioneer. A debt security is below investment grade if it is rated BB or lower by Standard &
Grade          Poor's Financial Services LLC or the equivalent rating by another nationally recognized statistical rating
Securities     organization or determined to be of equivalent credit quality by Amundi Pioneer. Debt securities rated below
("Junk         investment grade are commonly referred to as "junk bonds" and are considered speculative. Below investment grade debt
Bonds")        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           For purposes of the fund's credit quality policies, if a security receives different ratings from nationally
Rating         recognized statistical rating organizations, the fund will use the rating chosen by the portfolio manager as most
Considerations 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 under take 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
               portfolio securities, Amundi Pioneer will consider if any action is appropriate in light of the fund's investment
               objectives and policies. These ratings are used as criteria for the selection of portfolio securities, in addition to
               Amundi Pioneer's own assessment of the credit quality of potential investments.
------------------------------------------------------------------------------------------------------------------------------------
Commodity-     Commodities are assets that have tangible proper ties, such as oils, metals, and agricultural products. The fund may
Related        gain exposure to commodities through investment in funds, including ETFs, or through commodity-linked notes and other
Investments    commodity-linked derivatives. The fund also may invest in securities of issuers in commodity-related industries.
------------------------------------------------------------------------------------------------------------------------------------

                                    Equity and Fixed Income Investments

Non-U.S.       The fund may invest in securities of non-U.S. issuers, including securities of emerging markets issuers. Non-U.S.
Investments    issuersare 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, 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.
------------------------------------------------------------------------------------------------------------------------------------
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:
               -- 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, exposure to various market segments)
               -- 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     The fund may invest in inverse floating rate obligations (a type of derivative instrument). The interest rate on inverse
Floating    floating rate obligations will generally decrease as short-term interest rates increase, and increase as short-term
Rate        rates decrease. Due to their leveraged structure, the sensitivity of the market value of an inverse floating rate
Obligations 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.
------------------------------------------------------------------------------------------------------------------------------------
Cash        Normally, the fund invests substantially all of its assets to meet its investment objectives. The fund may invest the
Management  remainder of its assets in securities with remaining maturities of less than one year or cash equivalents, or may hold
and         cash. For temporary defensive purposes, including during periods of unusual cash flows, the fund may depart from its
Temporary   principal investment strategies and invest part or all of its assets in these securities or may hold cash. The fund may
Investments 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.
------------------------------------------------------------------------------------------------------------------------------------
Repurchase  In a repurchase agreement, the fund purchases securities from a broker/dealer or a bank, called the counterparty, upon
Agreements  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     The fund may enter into reverse repurchase agreements pursuant to which the fund transfers securities to a counterparty
Repurchase  in return for cash, and the fund agrees to repurchase the securities at a later date and for a higher price. Reverse
Agreements  repurchase agreements are treated as borrowings by the fund, are a form of leverage and may make the value of an
and         investment in the fund more volatile and increase the risks of investing in the fund. The fund also may borrow money
Borrowing   from banks or other lenders for temporary purposes. The fund may borrow up to 33 1/3% of its total assets. Entering 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  The fund usually does not trade for short-term profits. The fund will sell an investment, however, even if it has only
Trading     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. A higher level of portfolio turnover may also
            cause taxable shareowners to incur a higher level of taxable income or capital gains.

Policies
------------------------------------------------------------------------------------------------------------------------------------


Comparison of Principal Risks

     The following describe the common risks of investing in an Acquired Fund
     and the Acquiring 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 market prices 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. These
     conditions may continue, recur, worsen or spread. Events that have
     contributed to these market conditions include, but are not limited to,
     major cybersecurity events; measures to address U.S. federal and state
     budget deficits; downgrading of U.S. long-term sovereign debt; declines in
     oil and commodity prices; dramatic changes in currency exchange rates; and
     public sentiment. 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. 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 has
     reduced its market support activities and has begun raising interest rates.
     Certain foreign governments and central banks are implementing or
     discussing so-called negative interest rates (e.g., charging depositors who
     keep their cash at a bank) to spur economic growth. Further Federal Reserve
     or other U.S. or non-U.S. governmental or central bank actions, including
     interest rate increases or contrary actions by

                                       14



     different governments, 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 increasingly interconnected. Economic, financial or political
     events, trading and tariff arrangements, terrorism, natural disasters and
     other circumstances in one country or region could have profound impacts on
     global economies or markets. As a result, whether or not the fund invests
     in securities of issuers located in or with significant exposure to the
     countries directly affected, 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.

     Risk of investment in other funds. Investing in other investment companies,
     including ETFs, subjects the fund to the risks of investing in the
     underlying securities or assets held by those funds. Each underlying fund
     pursues its own investment objectives and strategies and may not achieve
     its objectives. When investing in another fund, the fund will bear a pro
     rata portion of the underlying fund's expenses, in addition to its own
     expenses. Consequently, an investment in the fund entails more direct and
     indirect expenses than a direct investment in the underlying funds.
     Underlying funds may themselves invest in other investment companies. The
     adviser may be subject to potential conflicts of interest in selecting
     underlying funds because the management fees paid to it by some affiliated
     underlying funds are higher than the fees paid by other affiliated and
     unaffiliated underlying funds. ETFs are bought and sold based on market
     prices and can trade at a premium or a discount to the ETF's net asset
     value. Mutual funds and ETFs that invest in commodities may be subject to
     regulatory trading limits that could affect the value of their securities.

     The underlying funds will not necessarily make consistent investment
     decisions, which may also increase your costs. One underlying fund may buy
     the same security that another underlying fund is selling. You would
     indirectly bear the costs of both trades without achieving any investment
     purpose. These transactions may also generate taxable gains. If you are a
     taxable shareholder, you may receive taxable distributions consisting of
     gains from transactions by the underlying funds as well as gains from the
     fund's transactions in shares of the underlying funds.

     Furthermore, Amundi Pioneer manages many of the underlying funds. Because
     the portfolio management teams of each of the affiliated underlying funds
     may draw upon the resources of the same equity and fixed income analyst
     team or may share common investment management styles or approaches, the
     underlying funds may hold many common portfolio positions, reducing the
     diversification benefits of an asset allocation style.

     Portfolio selection risk. The adviser's evaluation of asset classes and
     market sectors in developing an allocation model, and its selection and
     weighting of underlying funds, securities or other investments within the
     allocation model, may prove to be incorrect. To the extent that the fund
     invests a significant percentage of its assets in any one underlying fund,
     the fund will be subject to a greater degree to the risks particular to
     that underlying fund, and may experience greater volatility as a result. An
     underlying fund adviser's judgment about the attractiveness, relative value
     or potential appreciation of an equity security, or about the quality,
     relative yield or relative value of a fixed income security, or about a
     particular sector, region or market segment, or about an investment
     strategy, or about interest rates, may prove to be incorrect.

     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,
     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.

     Equity securities risk. Equity securities are subject to the risk that
     stock prices may rise and fall in periodic cycles and may perform poorly
     relative to other investments. This risk may be greater in the short term.
     Equity securities represent an ownership interest in an issuer, rank junior
     in a company's capital structure to debt securities and consequently may
     entail greater risk of loss than fixed income securities. Following is
     additional information regarding the risks of investing in equity
     securities.

     Value style risk. The prices of securities the adviser believes are
     undervalued may not appreciate as expected or may go down. Value stocks may
     fall out of favor with investors and underperform the overall equity
     market.

     Growth style risk. The fund's investments may not have the growth potential
     originally expected. Growth stocks may fall out of favor with investors and
     underperform the overall equity market.

                                       15



     Small and mid-size companies risk. Compared to large companies, small- and
     mid-size companies, and the market for their equity securities, may be more
     sensitive to changes in earnings results and investor expectations, have
     more limited product lines and capital resources, experience sharper swings
     in market values, have limited liquidity, be harder to value or to sell at
     the times and prices the adviser thinks appropriate, and offer greater
     potential for gain and loss.

     Risks of investments in real-estate related securities. The fund has risks
     associated with the real estate industry. Although the fund does not invest
     directly in real estate, it may invest in REITs and other equity securities
     of real estate industry issuers. These risks may include:

     o    The U.S. or a local real estate market declines due to adverse
          economic conditions, foreclosures, overbuilding and high vacancy
          rates, reduced or regulated rents or other causes

     o    Interest rates go up. Rising interest rates can adversely affect the
          availability and cost of financing for property acquisitions and other
          purposes and reduce the value of a REIT's fixed income investments

     o    The values of proper ties owned by a REIT or the prospects of other
          real estate industry issuers may be hurt by property tax increases,
          zoning changes, other governmental actions, environmental liabilities,
          natural disasters or increased operating expenses

     o    A REIT in the fund's portfolio is, or is perceived by the market to
          be, poorly managed

     o    If the fund's real estate related investments are concentrated in one
          geographic area or property type, the fund will be particularly
          subject to the risks associated with that area or property type

     REITs can generally be classified as equity REITs, mortgage REITs or hybrid
     REITs. Equity REITs invest primarily in real property and derive income
     mainly from the collection of rents. They may also realize gains or losses
     from the sale of proper ties. Equity REITs will be affected by conditions
     in the real estate rental market and by changes in the value of the proper
     ties they own. Mortgage REITs invest primarily in mortgages and similar
     real estate interests and derive income primarily from interest payments.
     Mortgage REITs will be affected by changes in creditworthiness of borrowers
     and changes in interest rates. Mortgage REITs are subject to the risks of
     default of the mortgages or mortgage-related securities in which they
     invest, and REITs that invest in so-called "sub-prime" mortgages are
     particularly subject to this risk. Hybrid REITs invest both in real
     property and in mortgages.

     Investing in REITs involves certain unique risks. REITs are dependent on
     management skills, are not diversified and are subject to the risks of
     financing projects. REITs are typically invested in a limited number of
     projects or in a particular market segment or geographic region, and
     therefore are more susceptible to adverse developments affecting a single
     project, market segment or geographic region than more broadly diversified
     investments. REITs are subject to heavy cash flow dependency, defaults by
     mortgagors or other borrowers and tenants, self-liquidation and the
     possibility of failing to qualify for certain tax and regulatory
     exemptions. REITs may have limited financial resources and may experience
     sharper swings in market values and trade less frequently and in a more
     limited volume than securities of larger issuers. In addition to its own
     expenses, the fund will indirectly bear its proportionate share of any
     management and other expenses paid by REITs in which it invests.

     Many real estate companies, including REITs, utilize leverage (and some may
     be highly leveraged), which increases investment risk and could adversely
     affect a real estate company's operations and market value. Mortgage REITs
     tend to be more leveraged than equity REITs. In addition, many mortgage
     REITs manage their interest rate and credit risks through the use of
     derivatives and other hedging techniques. In addition, capital to pay or
     refinance a REIT's debt may not be available or reasonably priced.
     Financial covenants related to real estate company leveraging may affect
     the company's ability to operate effectively.

     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.

                                       16



     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.

     Risks of warrants and rights. Warrants and rights give the fund the right
     to buy stock. A warrant specifies the amount of underlying stock, the
     purchase (or "exercise") price, and the date the warrant expires. The fund
     has no obligation to exercise the warrant and buy the stock. A warrant has
     value only if the fund is able to exercise it or sell it before it expires.
     If the price of the underlying stock does not rise above the exercise price
     before the warrant expires, the warrant generally expires without any value
     and the fund loses any amount it paid for the warrant. Thus, investments in
     warrants may involve substantially more risk than investments in common
     stock. Warrants may trade in the same markets as their underlying stock;
     however, the price of the warrant does not necessarily move with the price
     of the underlying stock.

     The fund may purchase securities pursuant to the exercise of subscription
     rights, which allow an issuer's existing shareholders to purchase
     additional common stock at a price substantially below the market price of
     the shares. The failure to exercise subscription rights to purchase common
     stock would result in the dilution of the fund's interest in the issuing
     company. The market for such rights is not well developed and, accordingly,
     the fund may not always realize full value on the sale of rights.

     Risks of initial public offerings. Companies involved in initial public
     offerings (IPOs) generally have limited operating histories, and prospects
     for future profitability are uncertain. Information about the companies may
     be available for very limited periods. The market for IPO issuers has been
     volatile, and share prices of newly public companies have fluctuated
     significantly over short periods of time. Further, stocks of newly-public
     companies may decline shortly after the IPO. There is no assurance that the
     fund will have access to IPOs. The purchase of IPO shares may involve high
     transaction costs. Because of the price volatility of IPO shares, the fund
     may choose to hold IPO shares for a very short period of time. This may
     increase the turnover of the portfolio and may lead to increased expenses
     to the fund, such as commissions and transaction costs. The market for IPO
     shares can be speculative and/or inactive for extended periods of time.
     There may be only a limited number of shares available for trading. The
     limited number of shares available for trading in some IPOs may also make
     it more difficult for the fund to buy or sell significant amounts of shares
     without an unfavorable impact on prevailing prices.

     Debt securities risk. Factors that could contribute to a decline in the
     market value of debt securities in the fund include rising interest rates,
     if the issuer or other obligor of a security held by the fund fails to pay
     principal and/or interest, otherwise defaults or has its credit rating
     downgraded or is perceived to be less creditworthy or the credit quality or
     value of any underlying assets declines. Junk bonds 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; they may also be more difficult to value. Junk
     bonds have a higher risk of default or are already in default and are
     considered speculative.

     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. 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.
     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. The maturity of a security may be significantly longer
     than its effective duration. A security's maturity may be more relevant
     than its effective duration in determining the security's sensitivity to
     other factors such as changes in credit quality or in the yield premium
     that the market may establish for certain types of securities. 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.

                                       17



     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.

     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 (the estimated period until the security
     is paid in full) 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 is the risk that particular investments, or
     investments generally, may be 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 during periods of market
     turmoil. Liquidity and value of investments can deteriorate rapidly.
     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, especially in changing markets. 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. The fund may experience heavy
     redemptions that could cause the fund to liquidate its assets at
     inopportune times or at a loss or depressed value, which could cause the
     value of your investment to decline. 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. Further, certain
     securities, once sold, may not settle for an extended period (for example,
     several weeks or even longer). The fund will not receive its sales proceeds
     until that time, which may constrain the fund's ability to meet its
     obligations (including obligations to redeeming shareholders). 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.

     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 FNMA, FHLMC and the 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
                                       18


     nor issued by the U.S. government. The maximum potential liability of the
     issuers of some U.S. government obligations may greatly exceed their
     current resources, including any legal right to support from the U.S.
     government. Such debt and mortgage-backed securities 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 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 proper ty.
     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
     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

                                       19



     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.

     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 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. Issuers of
     junk bonds may have a larger amount of outstanding debt relative to their
     assets than issuers of investment grade bonds. 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. Market quotations for these securities may be volatile
     and/or subject to large spreads between bid and ask prices. No active
     trading market may exist for many floating rate loans, and many loans are
     subject to restrictions on resale. Any secondary market may be subject to
     irregular trading activity and extended trade settlement periods. In
     particular, loans may take longer than seven days to settle, potentially
     leading to the sale proceeds of loans not being available to meet
     redemptions for a substantial period of time after the sale of the loans.
     To the extent that sale proceeds of loans are not available, the fund may
     sell securities that have shorter settlement periods or may access other
     sources of liquidity to meet redemption requests. 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 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
     afforded by 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

                                       20



     (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. As a result, even a
     perceived decline in creditworthiness of the issuer is likely to have a
     greater impact on subordinated securities.

     Inflation-linked security risk. Unlike a conventional bond, whose issuer
     makes regular fixed interest payments and repays the face value of the bond
     at maturity, an inflation-indexed security provides principal payments and
     interest payments, both of which are adjusted over time to reflect a rise
     (inflation) or a drop (deflation) in the general price level. The inflation
     index generally used is a non-seasonally adjusted index, which is not
     statistically smoothed to overcome highs and lows observed at different
     points each year. The use of a non-seasonally adjusted index can cause the
     fund's income level to fluctuate. As inflationary expectations increase,
     inflation-linked securities will become more attractive, because they
     protect future interest payments against inflation. Conversely, as
     inflationary concerns decrease, inflation-linked securities will become
     less attractive and less valuable. The inflation index used may not
     accurately measure the real rate of inflation. Inflation-linked securities
     may lose value or interest payments on such securities may decline in the
     event that the actual rate of inflation is different than the rate of the
     inflation index, and losses may exceed those experienced by other debt
     securities with similar durations. The values of inflation-linked
     securities may not be directly correlated to changes in interest rates, for
     example if interest rates rise for reasons other than inflation.

     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. 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 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
          securities at times, in amounts and at prices it considers reasonable


                                       21



     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. A number of countries in Europe have suffered
          terror attacks, and additional attacks may occur in the future. In
          addition, voters in the United Kingdom have approved withdrawal from
          the EU. Other countries may seek to withdraw from the EU and/or
          abandon the euro, the common currency of the EU. These events could
          negatively affect the value and liquidity of the fund's investments,
          particularly in euro- denominated securities and derivative contracts,
          securities of issuers located in the EU or with significant exposure
          to EU issuers or countries

     Additional risks of investing in emerging markets include:

     o    The extent of economic development, political stability, market depth,
          infrastructure, capitalization and regulatory oversight can be less
          than in more developed markets

     o    Emerging market countries may experience rising interest rates, or,
          more significantly, rapid inflation or hyperinflation

     o    The fund could experience a loss from settlement and custody practices
          in some emerging markets

     o    The possibility that a counterparty may not complete a currency or
          securities transaction

     o    Low trading volumes may result in a lack of liquidity and in extreme
          price volatility

     o    Current and any future sanctions or other government actions against
          Russia could negatively impact the fund's investments in securities
          issued by Russian issuers or economically tied to Russian markets

     o    China and other developing market Asia-Pacific countries may be
          subject to considerable degrees of economic, political and social
          instability

     Currency risk. Because the fund may invest in non-U.S. currencies,
     securities denominated in non-U.S. currencies, and other currency-related
     investments, the fund is subject to currency risk, meaning that the fund
     could experience losses based on changes in the exchange rate between
     non-U.S. currencies and the U.S. dollar or as a result of currency
     conversion costs. Currency exchange rates can be volatile, and are affected
     by factors such as general economic conditions, the actions of the U.S. and
     foreign governments or central banks, the imposition of currency controls
     and speculation.

     Forward foreign currency transactions risk. To the extent that the fund
     enters into forward foreign currency transactions, it may not fully benefit
     from or may lose money on the transactions if changes in currency rates do
     not occur as anticipated or do not correspond accurately to changes in the
     value of the fund's holdings, or if the counterparty defaults. Such
     transactions may also prevent the

                                       22



     fund from realizing profits on favorable movements in exchange rates. Risk
     of counterparty default is greater for counterparties located in emerging
     markets. The fund's ability to use forward foreign currency transactions
     successfully depends on a number of factors, including the forward foreign
     currency transactions being available at prices that are not too costly,
     the availability of liquid markets, and Pioneer's judgment regarding the
     direction of changes in currency exchange rates.

     Commodity investments risk. Certain underlying funds may invest directly or
     indirectly in commodities. Exposure to the commodities markets may subject
     the fund to greater volatility than investments in other securities. The
     value of commodity-linked notes and other commodity-linked derivatives may
     be affected by changes in overall market movements, commodity index
     volatility, changes in interest rates, or factors affecting a particular
     industry or commodity, such as drought, floods, weather, livestock disease,
     embargoes, tariffs and international economic, political and regulatory
     developments. The prices of energy, industrial metals, precious metals,
     agriculture and livestock sector commodities may fluctuate widely and
     rapidly due to factors such as changes in value, supply and demand and
     governmental regulatory policies. Commodity-related investments may be more
     volatile and less liquid than the underlying commodities, instruments or
     measures, which may make it difficult for such investments to be sold at a
     price acceptable to the adviser or to accurately value them.
     Commodity-related investments are subject to the credit risks associated
     with the issuer, and their values may decline substantially if the issuer's
     creditworthiness deteriorates. As a result, returns of commodity-linked
     investments may deviate significantly from the return of the underlying
     commodity, instruments or measures. The portfolio may receive lower
     interest payments (or not receive any of the interest due) on an investment
     in a commodity-linked note if there is a loss of value of the underlying
     investment. Further, to the extent that the amount of principal to be
     repaid upon maturity is limited to the value of a particular commodity,
     commodity index or other economic variable, the portfolio might not receive
     a portion (or any) of the principal at maturity of the investment or upon
     earlier exchange.

     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 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 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. In
     addition, the SEC has proposed a new rule that would change the regulation
     of the use of derivatives by registered investment companies, such as the
     fund. If the proposed rule takes effect, it could limit the ability of the
     fund to invest in derivatives.

                                       23



     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.

     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 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 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 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 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.

     Short position risk. Taking short positions involves leverage of the fund's
     assets and presents various risks. If the price of the instrument or market
     on which the fund has taken a short position increases, then the fund will
     incur a loss. Because of leverage, taking short positions involves the risk
     that losses may be exaggerated, potentially more than the actual cost of
     the investment. Unlike purchasing a financial instrument like a stock,
     where potential losses are limited to the purchase price and there is no
     upside limit on potential gain, short sales involve no cap on maximum
     losses. Also, there is the risk that a counterparty may fail to perform the
     terms of the arrangement, causing a loss to the fund. In the short sale of
     an instrument, the fund must first borrow the instrument from a lender,
     such as a broker or other institution. The fund may not always be able to
     borrow the instrument at a particular time or at an acceptable price. Thus,
     there is risk that the fund may be unable to implement its investment
     strategy due to the lack of available financial instruments or for other
     reasons.

     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, such as ETFs, 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.

     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. The fund may value investments
     using fair value methodologies. 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 securities or had
     used a different valuation methodology. 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. The fund's
     ability to value its investments may also be impacted by technological
     issues and/or errors by pricing services or other third party service
     providers.

     Redemption risk. The fund may experience periods of heavy redemptions that
     could cause the fund to liquidate its assets at inopportune times or at a
     loss or depressed value, particularly during periods of declining or
     illiquid markets. Redemption risk is greater to the extent that the fund
     has investors with large shareholdings, short investment horizons, or
     unpredictable cash flow needs. In addition, redemption risk is heightened
     during periods of overall market turmoil. The redemption by one or more
     large shareholders of their holdings in the fund could hurt performance
     and/or cause the remaining shareholders in the fund to lose money. If one
     decision maker has control of fund shares owned by separate fund
     shareholders, including clients or affiliates of the fund's adviser,
     redemptions by these shareholders may further increase the fund's
     redemption risk. If the fund is forced to liquidate its assets under
     unfavorable conditions or at inopportune times, the value of your
     investment could decline.

     Non-diversification risk. To the extent an underlying fund is not
     diversified, the underlying fund can invest a higher percentage of its
     assets in the securities of any one or more issuers than a diversified
     fund. Being non-diversified may magnify the fund's and the underlying
     fund's losses from adverse events affecting a particular issuer.

     Portfolio turnover risk. 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.

     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 objective.

     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.

Comparison of Fees and Expenses

     Shareholders of each Pioneer Fund pay various fees and expenses, either
directly or indirectly. The tables below show the fees and expenses that you
would pay if you were to buy and hold shares of each Pioneer Fund. The expenses
in the tables appearing below are based on the expenses of each Pioneer Fund
and the combined fund for the twelve-month period ended July 31, 2017. Future
expenses for all share classes may be greater or less.

     Because both Pioneer Solutions -- Conservative Fund and Pioneer Solutions
-- Growth Fund may reorganize with Pioneer Solutions--Balanced Fund, the pro
forma columns represent the three possibilities that may result: (1) both
Acquired Funds complete their Reorganizations; (2) only Pioneer Solutions --
Conservative Fund completes its Reorganization; or (3) only Pioneer Solutions
-- Growth Fund completes its Reorganization.

(1)  Class A purchases of $500,000 or more that are not subject to an initial
     sales charge may be subject to a contingent deferred sales charge of 1%.
     See "Sales charges."

(2)  Total annual fund operating expenses in the table, before and after fee
     waiver and expense reimbursement, may be higher than the corresponding
     ratio of expenses to average net assets shown in the "Financial Highlights"
     section, which does not include acquired fund fees and expenses.

(3)  With respect to the Pioneer Solutions -- Conservative Fund, Amundi Pioneer
     has contractually agreed to limit ordinary operating expenses (ordinary
     operating expenses means all fund expenses other than taxes, brokerage
     commissions, acquired fund fees and expenses and extraordinary expenses,
     such as litigation) to the extent required to reduce fund expenses to
     0.70%, 1.45%, 0.90% and 0.65% of the average daily net assets attributable
     to Class A, Class C, Class R and Class Y shares, respectively. These
     expense limitations are in effect through December 1, 2019. There can be no
     assurance that Amundi Pioneer will extend the expense limitation beyond
     such time. While in effect, the arrangement may be terminated for a class
     only by agreement of Amundi Pioneer and the Board of Trustees. The expense
     limitation does not limit the expenses of the underlying funds indirectly
     incurred by a shareholder.

     With respect to the Pioneer Solutions -- Growth Fund, Amundi Pioneer has
     contractually agreed to limit ordinary operating expenses (ordinary
     operating expenses means all fund expenses other than taxes, brokerage
     commissions, acquired fund fees and expenses and extraordinary expenses,
     such as litigation) to the extent required to reduce fund expenses to 0.90%
     of the average daily net assets attributable to Class R shares. This
     expense limitation is in effect through December 1, 2019. There can be no
     assurance that Amundi Pioneer will extend the expense limitation beyond
     such time. While in effect, the arrangement may be terminated for a class
     only by agreement of Amundi Pioneer and the Board of Trustees. The expense
     limitation does not limit the expenses of the underlying funds indirectly
     incurred by a shareholder.

     With respect to the Pioneer Solutions -- Balanced Fund, Amundi Pioneer has
     contractually agreed to limit ordinary operating expenses (ordinary
     operating expenses means all fund expenses other than taxes, brokerage
     commissions, acquired fund fees and expenses and extraordinary expenses,
     such as litigation) to the extent required to reduce fund expenses to 0.90%
     of the average daily net assets attributable to Class R shares. Amundi
     Pioneer has agreed to further limit the ordinary expenses of Class R shares
     of the combined fund following the completion of the Reorganization to
     0.78% of the average daily net assets attributable to Class R shares. These
     expense limitations are in effect through December 1, 2019. There can be no
     assurance that Amundi Pioneer will extend the expense limitation beyond
     such time. While in effect, the arrangement may be terminated for a class
     only by agreement of Amundi Pioneer and the Board of Trustees. The expense
     limitation does not limit the expenses of the underlying funds indirectly
     incurred by a shareholder.

(4)  Following the completion of the Reorganizations, the combined fund will not
     pay a direct management fee to Amundi Pioneer. However, as is currently the
     case for each of the funds, following the completion of the
     Reorganizations, the combined fund will continue to bear a pro rata portion
     of the fees and expenses, including management fees, of each underlying
     fund in which the combined fund invests. The pro rata portion of the fees
     and expenses of each underlying fund in which each fund invests is shown in
     the Fee Table under Acquired Fund Fees and Expenses.

Examples:

The examples are intended to help you compare the cost of investing in each
fund with the cost of investing in other mutual funds. The examples assume that
you invest $10,000 in each fund for the time periods shown, and then, except as
indicated, redeem all of your shares at the end of those periods. The examples
also assume that (a) your investment has a 5% return each year and (b) each
fund's total annual operating expenses remain the same except for year one
(which considers the effect of the expense limitation). Pro forma expenses are
included assuming consummation of the Reorganization as of July 31, 2017. The
examples are for comparison purposes only and are not a representation of any
fund's actual expenses or returns, either past or future. Although your actual
costs may be higher or lower, based on these assumptions your costs would be:

Comparison of the Funds' Past Performance

     The bar charts and tables below indicate the risks and volatility of an
investment in the funds by showing how the funds have performed in the past.
The bar charts show changes in the performance of each fund's Class A shares
from calendar year to calendar year. The tables show the average annual total
returns for each class of each fund over time and compare these returns to the
returns of the MSCI World Index and the Bloomberg Barclays U.S. Aggregate Bond
Index, each a broad-based measure of market performance that has
characteristics relevant to each fund's investment strategies, and a blended
benchmark (80% Bloomberg Barclays U.S. Aggregate Bond Index/20% MSCI World
Index for each of the Acquired Funds, and 50% Bloomberg Barclays U.S. Aggregate
Bond Index/50% MSCI World Index for the Acquiring Fund). You can obtain updated
performance information by visiting
https://us.pioneerinvestments.com/performance or by calling 1-800-225-6292.

     A fund's past performance (before and after taxes) does not necessarily
indicate how it will perform in the future. The bar charts do not reflect any
sales charge you may pay when you buy fund shares. If this amount was
reflected, returns would be less than those shown.

     Ibbotson Associates, Inc. served as the funds' sub-adviser until November
14, 2014. Effective November 17, 2014, Amundi Pioneer became directly
responsible for portfolio management decisions for the funds. The performance
shown for all periods reflects the investment strategy in effect for the funds
during such periods.

Reasons for each Reorganization

     The Board of Trustees believes that each proposed Reorganization will be
advantageous to the shareholders of the applicable Acquired Fund for several
reasons. The Trustees considered the following matters, among others, in
approving each Reorganization.

     First, the Board considered that the expense ratio of each class of shares
of the combined fund is expected to be no higher than the expense ratio of the
corresponding class of shares of the Acquired Fund, both before and after any
applicable fee waivers or expense reimbursements. The Board concluded that the
expected lower expense ratios of the combined fund supported a determination
that the Reorganization is in the best interests of shareholders.

     Second, the Board considered that the combined fund will no longer pay a
direct management fee to Amundi Pioneer, unlike the Acquired Fund and the
Acquiring Fund. The Board considered that, as is currently the case for the
Acquired Fund and the Acquiring Fund, the combined fund will continue to bear a
pro rata portion of the fees and expenses, including management fees, of each
underlying fund in which the combined fund invests. The Board considered that
the pro rata portion of the management fees of underlying Amundi Pioneer funds
borne by the combined fund following the completion of the Reorganization is
not expected to exceed the direct management fee and the pro rata portion of
the management fees of underlying Amundi Pioneer funds currently borne by the
Acquired Fund. The Board concluded that the elimination of the direct
management fee of the combined fund supported a determination that the
Reorganization is in the best interests of shareholders.

     Third, the Board considered that the Acquired Fund and the Acquiring Fund
held similar investments and noted that the historical performance of the
Acquired Fund and the Acquiring Fund was generally comparable. The Board
concluded that the historical performance of each fund was consistent with the
determination that the Reorganization is in the best interests of
shareholders.

     Fourth, the Board considered that the Acquired Fund has not achieved a
sufficient size to allow for more efficient operations. The Board considered
that the larger asset size of the combined fund may allow it, relative to the
Acquired Fund, to reduce per share expenses as fixed expenses will be shared
over a larger asset base. The Board concluded that the larger asset size of the
combined fund supported a determination that the Reorganization is in the best
interests of shareholders.

     Fifth, the Board considered the similarities and differences in the funds'
investment objectives and principal investment strategies. The Board considered
that the Acquired Fund and the Acquiring Fund have the same investment
objective to provide long-term capital growth and current income. The Board
considered that each fund is a "fund of funds" that allocates its assets
primarily among other

                                       34



underlying funds, including underlying funds managed by Amundi Pioneer and
underlying funds unaffiliated with Amundi Pioneer. The Board considered that
following the completion of the Reorganization, it is anticipated that the
combined fund will invest to a greater extent in underlying funds managed by
Amundi Pioneer. The Board considered that currently, Amundi Pioneer selects
investments for each fund while maintaining a target annualized volatility
level that corresponds to the fund's relative risk profile. The Board
considered that Amundi Pioneer will not seek to maintain a target annualized
volatility level for the combined fund or use derivatives to seek incremental
return or to seek to limit risk. The Board considered such similarities and
differences and considered that shareholders would receive information
regarding the Reorganization and would have the ability to redeem their shares
of the Acquired Fund prior to the Closing Date if they determine that they do
not wish to become shareholders of the combined fund.

     The Board considered that the Reorganization, itself, generally is not
expected to result in income, gain or loss being recognized for federal income
tax purposes by the Acquired Fund, the Acquiring Fund or by the shareholders of
any fund. The Board noted that it is not necessary to dispose of securities to
effect the Reorganization; however, following the completion of the
Reorganization, the combined fund will invest to a greater extent in underlying
funds managed by Amundi Pioneer. The implementation of such investment strategy
changes for the combined fund is expected to result in the disposition of
approximately 25% of the securities of the combined fund following the
Reorganization. Shareholders of the combined fund are expected to recognize
long-term capital gains of approximately $1,237,831, or approximately $0.03 per
share, in connection with the disposition of securities following the completion
of the Reorganization. It is expected that such capital gains will be offset by
available tax capital-loss carryforwards and, accordingly, that no material
distributions to shareholders as a result of the disposition of securities is
anticipated. The Board concluded that the expected tax consequences of the
Reorganization were consistent with a determination that the Reorganization is
in the best interests of each fund's shareholders.

     The Board also noted that the disposition of securities is not expected to
result in significant brokerage expenses to the combined fund. The Board also
noted that the actual tax consequences of any dispositions of portfolio
securities following the completion of the Reorganization will vary depending
upon the specific security(ies) being sold.

     The Board concluded that, taking into account the anticipated benefits to
shareholders resulting from each Reorganization, including anticipated lower
expenses, on balance the Reorganization is in the best interests of
shareholders not withstanding differences in the funds' investment strategies.

     Sixth, the Board considered that each Acquired Fund would generally bear
approximately 25% of the expenses incurred in connection with its
Reorganization, including expenses associated with the preparation, printing
and mailing of any shareholder communications (including this Information
Statement/Prospectus), any filings with the SEC and other governmental agencies
in connection with its Reorganization, audit fees and legal fees, and the
Acquiring Fund would likewise generally bear approximately 25% of these costs
for each Reorganization. The Board considered that Amundi Pioneer would
generally bear the remaining 50% of the expenses incurred in connection with
each Reorganization. In approving the allocation of Reorganization Costs, the
Board considered information provided by Amundi Pioneer with respect to the
relative short-term economic benefits and costs to shareholders anticipated to
result from each Reorganization. The Board concluded that the allocation of
Reorganization Costs was consistent with a determination that the
Reorganization is in the best interests of shareholders.

     Seventh, the Board considered that the funds' investment adviser and
principal distributor would benefit from each Reorganization. For example,
Amundi Pioneer might achieve cost savings from managing one larger fund
compared to managing more than one fund with similar investment strategies. The
consolidated portfolio management effort also might result in time and
personnel savings and the preparation of fewer reports and regulatory filings,
as well as prospectus disclosure, for one fund instead of three. The Board
believes that each Reorganization, in the long-term, could result in a decrease
in the combined fund's gross expenses.

                   BOARDS' EVALUATION OF THE REORGANIZATIONS

     For the reasons described above, the Board of Trustees of each Acquired
Fund, including the Independent Trustees, approved the applicable
Reorganization. In particular, the Board of Trustees determined, with respect
to each Acquired Fund, that the Reorganization of such Acquired Fund is in the
best interests of such Acquired Fund and its shareholders and is not dilutive
of the interests of those shareholders. Similarly, the Board of Trustees of the
Acquiring Fund, including the Independent Trustees, approved each
Reorganization. The Trustees also determined that the Reorganization of each
Acquired Fund with the Acquiring Fund is in the best interests of the Acquiring
Fund and its shareholders and is not dilutive of the interests of those
shareholders.

                                 CAPITALIZATION

     The following table sets forth the capitalization of each Pioneer Fund as
of September 29, 2017, and the pro forma combined capitalization of the combined
fund as if each Reorganization occurred on that date. The actual exchange ratios
on the Closing Date may vary from the exchange ratios indicated. This is due to
changes in the market value of the portfolio securities of the Pioneer Funds
between September 29, 2017 and the Closing Date, changes in the amount of
undistributed net investment income and net realized capital gains of the
Pioneer Funds during that period resulting from income and distributions, and
changes in the accrued liabilities of the Pioneer Funds during the same period.

     Because both Acquired Funds may reorganize with the Acquiring Fund, the
following pro forma combined capitalization tables show the three possibilities
that may result: (1) both Acquired Funds reorganize with the Acquiring Fund; (2)
only Pioneer Solutions - Conservative Fund reorganizes with the Acquiring Fund;
or (3) only Pioneer Solutions - Growth Fund reorganizes with the Acquiring Fund.

(1)  The pro forma data reflects adjustments to account for the combined
     expenses of the Reorganizations borne by the Acquired Funds and the
     Acquiring Fund. The expenses of the Reorganizations borne by the funds are
     estimated in the aggregate to be $75,000. Amundi Pioneer will bear the
     remaining expenses of the Reorganization.

     It is impossible to predict how many shares of the combined fund will
actually be received and distributed by your fund on the Closing Date. The table
should not be relied upon to determine the amount of combined fund shares that
will actually be received and distributed.

           OTHER IMPORTANT INFORMATION CONCERNING THE REORGANIZATIONS

                              Portfolio Securities

     It is not necessary to dispose of securities to effect either
Reorganization. However, it is currently anticipated that, following the
completion of the Reorganizations, the combined fund will invest to a greater
extent in underlying funds managed by Amundi Pioneer. The implementation of
such investment strategy changes for the combined fund is expected to result in
the disposition of approximately 25% of the securities of the combined fund
following the Reorganizations. The disposition of securities is not expected to
result in significant brokerage expenses to the combined fund.

     Shareholders of the combined fund are expected to recognize long-term
capital gains of approximately $1,237,831, or approximately $0.03 per share, in
connection with the disposition of securities following the completion of the
Reorganizations. It is expected that such capital gains will be offset by
available tax capital-loss carryforwards and, accordingly, that no material
distributions to shareholders as a result of the disposition of securities is
anticipated. The actual tax consequences of any disposition of portfolio
securities will vary depending upon the specific security(ies) being sold,
other capital gains and losses that may be recognized, and the combined fund's
ability to use any available tax loss carryforwards.

     In addition, after the closing of each Reorganization, management will
continue to analyze and evaluate the portfolio securities of the combined fund,
and it is possible that there may be additional dispositions of portfolio
securities of the combined fund following each Reorganization. Consistent with
the combined fund's investment objective and policies, any restrictions imposed
by the Internal Revenue Code and in the best interests of the shareholders of
the combined fund, management will influence the extent and duration to which
the portfolio securities of the applicable Acquired Fund and the Acquiring Fund
will be maintained by the combined fund. Subject to market conditions at the
time of any such disposition, the disposition of the portfolio securities by
the combined fund may result in a capital gain or loss. As noted above, the
actual tax consequences of any disposition of portfolio securities will vary
depending upon the specific security(ies) being sold, other capital gains and
losses that may be recognized, and the combined fund's ability to use any
available tax loss carryforwards.

                         Tax Capital Loss Carryforwards

     Federal income tax law generally permits a regulated investment company to
carry forward indefinitely net capital losses from any taxable year to offset
its capital gains. Presently, the net capital loss carryforwards of each
Acquired Fund and the Acquiring Fund from their prior taxable years can be
summarized as follows:

Fund                                      Capital Loss Carryforward
-------------------------------------------------------------------
Pioneer Solutions -- Conservative Fund          $1,630,428
-------------------------------------------------------------------
Pioneer Solutions -- Growth Fund                        $0
-------------------------------------------------------------------
Pioneer Solutions -- Balanced Fund              $4,780,532
-------------------------------------------------------------------

     For the period ending on the Closing Date, each fund may have net realized
capital gains or losses and as of the Closing Date a fund may also have net
unrealized capital gains or losses.

     Each Reorganization may result in a number of limitations on the combined
fund's ability to use realized and unrealized losses of the combining funds.
The discussion below describes the limitations that may apply based on the
funds' tax attributes and relative net asset values as of July 31, 2017. Since
the Reorganizations are not expected to close until January 19, 2018, the net
current-year realized capital gains and losses and net unrealized capital gains
and losses and the effect of the limitations described may change significantly
between now and the completion of the Reorganizations. Further, the ability of
the Acquired Funds and the Acquiring Fund to use capital losses to offset gains
(even in the absence of the Reorganizations) depends on factors other than loss
limitations, such as the future realization of capital gains or losses.

     First, in the tax year of the combined fund in which a Reorganization
occurs, the combined fund will be able to use carryforwards of the applicable
Acquired Fund (including from the Acquired Fund's short taxable year ending on
the applicable Closing Date), subject to the limitations described in the
following paragraphs, to offset only a prorated portion of the combined fund's
capital gains for such tax year, based on the number of days remaining in the
combined fund's tax year after the applicable Closing Date.

                                       39



     Second, each Reorganization may result in a limitation on the combined
fund's ability to use the applicable Acquired Fund's capital loss carryforwards
and, in certain cases, net unrealized losses inherent in the Acquired Fund's
assets at the time of the Reorganization, in subsequent tax years. This
limitation, imposed by Section 382 of the Internal Revenue Code, will apply if
the applicable Acquired Fund's shareholders own less than 50% of the combined
fund immediately after its Reorganization. This limitation is imposed on an
annual basis. Losses in excess of the limitation may be carried forward,
subject to generally applicable limitations. If applicable, the annual
limitation described in this paragraph for periods following the applicable
Reorganization generally will equal the product of the net asset value of the
applicable Acquired Fund immediately prior to the Reorganization and the
"long-term tax-exempt rate," published by the Internal Revenue Service, in
effect at the time of the Reorganization (as of July 31, 2017, the annual
limitation would be $1,168,885). This limitation may be prorated in the taxable
year in which the applicable Reorganization occurs based on the number of days
remaining after the Closing Date in such taxable year.

     Third, each Reorganization may result in limitations on the combined
fund's ability to use loss carryforwards of the Acquiring Fund, a portion of
losses recognized by the Acquiring Fund in the taxable year in which the
Reorganization occurs, and, in certain cases, a net unrealized loss inherent in
the assets of the Acquiring Fund at the time of the Reorganization. This
limitation will apply if the Acquiring Fund's shareholders own less than 50% of
the combined fund immediately after the applicable Reorganization. These
limitations are imposed on an annual basis. Losses in excess of the limitations
may be carried forward, subject to the generally applicable limitations on the
carryforward of losses. The aggregate annual limitation described in this
paragraph for periods following the applicable Reorganization generally will
equal the product of the net asset value of the Acquiring Fund immediately
prior to the Reorganization and the "long-term tax-exempt rate," published by
the Internal Revenue Service, in effect at the time of the Reorganization (as
of July 31, 2017, the annual limitation would be $1,168,885). This limitation
may be prorated in the taxable year in which the applicable Reorganization
occurs based on the number of days remaining after the Closing Date in such
taxable year.

     Fourth, as to each Reorganization, if the Acquired Fund or the Acquiring
Fund has a net unrealized gain inherent in its assets at the time of the
Reorganization, then, under certain circumstances, the combined fund may not
offset that gain, to the extent realized within five years of the
Reorganization, by a carryforward of pre-Reorganization losses (other than a
carryforward of pre-Reorganization losses of the fund with the net unrealized
gain) or, in certain cases, by a net unrealized loss inherent at the time of
the Reorganization in the assets of the other fund. This limitation will
generally apply if the Acquiring Fund's or the applicable Acquired Fund's
unrealized capital gains as of the date of the applicable Reorganization are
greater than $10,000,000 or 15% of the fair market value of its assets as of
the Closing Date.

     As of July 31, 2017, the funds had the following net unrealized gains or
losses and current-year net realized capital gains or losses:



Fund                                           Current-Year Realized Capital Gains/(Losses)        Net Unrealized Gains/(Losses)
--------------------------------------------------------------------------------------------------------------------------------
                                                                                                   
Pioneer Solutions -- Conservative Fund                                                 $0                         $1,821,912
--------------------------------------------------------------------------------------------------------------------------------
Pioneer Solutions -- Growth Fund                                              ($1,427,838)                       $36,055,988
--------------------------------------------------------------------------------------------------------------------------------
Pioneer Solutions -- Balanced Fund                                                     $0                        $15,746,285
--------------------------------------------------------------------------------------------------------------------------------


     Fifth, any capital loss carryforwards from prior years, any net
current-year capital losses, and, potentially, any unrealized capital losses
will benefit the shareholders of the combined fund, rather than only the
shareholders of the combining fund that incurred the loss. Even if a particular
limitation described above would not be triggered solely by a particular
Reorganization, the limitation may be triggered by the Reorganization and one
or more other transactions entered into by the Acquiring Fund or the applicable
Acquired Fund (including, potentially, the Reorganization of the other Acquired
Fund). By reason of the foregoing rules, shareholders of an Acquired Fund that
are not generally exempt from federal income taxation may pay more taxes, or
pay taxes sooner, than they otherwise would have if the Acquired Fund's
Reorganization did not occur.

                                       40



               TERMS OF THE AGREEMENT AND PLAN OF REORGANIZATION

The Reorganizations

     o    Each Reorganization is scheduled to occur as of the close of business
          on January 19, 2018 but may occur on such later date as the parties
          may agree to in writing.

     o    Each Acquired Fund will transfer all of its assets to the Acquiring
          Fund. The Acquiring Fund will assume all of the Acquired Fund's
          liabilities. The net asset value of each Pioneer Fund will be computed
          as of the close of regular trading on the New York Stock Exchange on
          the Closing Date.

     o    The Acquiring Fund will issue Class A, Class C, Class R and Class Y
          shares to each Acquired Fund with an aggregate net asset value equal
          to the aggregate net asset value of the Acquired Fund's Class A, Class
          C, Class R and Class Y shares, respectively.

     o    Shares of the Acquiring Fund will immediately be distributed to you on
          a class-by-class basis in proportion to the relative net asset value
          of your holdings of shares of each class of the applicable Acquired
          Fund on the Closing Date. As a result, each Acquired Fund's Class A,
          Class C, Class R and Class Y shareholders will end up as Class A,
          Class C, Class R and Class Y shareholders, respectively, of the
          Acquiring Fund. The shares of each class of Acquiring Fund shares that
          you receive in a Reorganization will have the same aggregate net asset
          value as your holdings of shares of the corresponding class of the
          applicable Acquired Fund immediately prior to the Reorganization. The
          net asset value attributable to a class of shares of each fund will be
          determined using the Pioneer Funds' valuation policies and procedures.
          Each fund's valuation policies and procedures are identical.

     o    After the shares are issued, the applicable Acquired Fund will be
          dissolved.

     o    No sales load, contingent deferred sales charge, commission,
          redemption fee or other transactional fee will be charged as a result
          of the Reorganizations. After each Reorganization, any contingent
          deferred sales charge that applied to Class A (if applicable) or Class
          C shares of the Acquired Fund at the time of the Reorganization will
          continue to apply for the remainder of the applicable holding period
          at the time of the Reorganization. In calculating any applicable
          contingent deferred sales charge, the period during which you held
          your shares will be included in the holding period of the shares of
          the combined fund you receive as a result of the applicable
          Reorganization.

     o    Each Reorganization, itself, generally is not expected to result in
          gain or loss being recognized for federal income tax purposes by
          shareholders of your fund or the Acquiring Fund, or by either your
          fund or the Acquiring Fund, except as set forth below under the
          heading "Tax Status of the Reorganizations." A Reorganization will not
          take place unless both funds involved in the Reorganization receive a
          tax opinion from Morgan, Lewis & Bockius LLP, counsel to the funds, as
          described below under the heading "Tax Status of the Reorganizations."

Agreement and Plan of Reorganization

     The Agreement and Plan of Reorganization with respect to the
Reorganizations is attached as Exhibit A to this Information
Statement/Prospectus. Material provisions of the Agreement and Plan of
Reorganization are described below, but are qualified in their entirety by the
attached copy.

     Cancellation of Share Certificates. If your shares are represented by one
or more share certificates before the Closing Date, on the Closing Date all
certificates will be canceled, will no longer evidence ownership of the
applicable Acquired Fund's shares and will evidence ownership of shares of the
combined fund. The combined fund will not issue share certificates in the
Reorganizations.

     Conditions to Closing the Reorganization. The obligation of each Acquired
Fund to consummate its Reorganization with the Acquiring Fund is subject to the
satisfaction of certain conditions, including the performance by the Acquiring
Fund of all its obligations under the Agreement and Plan of Reorganization and
the receipt of all consents, orders and permits necessary to consummate the
Reorganization (see Agreement and Plan of Reorganization, Section 6).

     The obligation of the Acquiring Fund to consummate a Reorganization with
an Acquired Fund is subject to the satisfaction of certain conditions,
including such Acquired Fund's performance of all of its obligations under the
Agreement and Plan of Reorganization, the receipt of certain documents and
financial statements from such Acquired Fund and the receipt of all consents,
orders and permits necessary to consummate the Reorganization (see Agreement
and Plan of Reorganization, Section 7).

     The funds' obligations are subject to the receipt of a favorable opinion
of Morgan, Lewis & Bockius LLP as to the federal income tax consequences of the
applicable Reorganization (see Agreement and Plan of Reorganization, Section
8.4).

                                       41



     Termination of Agreement and Plan of Reorganization. The Board of Trustees
of any fund involved in a Reorganization may terminate the Agreement and Plan
of Reorganization with respect to that Reorganization at any time before the
Closing Date of such Reorganization, if the Board believes that proceeding with
such Reorganization would no longer be in the best interests of shareholders of
the applicable fund.

     Expenses of the Reorganization. Each Acquired Fund will bear approximately
25% of the expenses incurred in connection with the Reorganization of such
Acquired Fund, including expenses associated with the preparation, printing and
mailing of any shareholder communications (including this Information
Statement/Prospectus), any filings with the SEC and other governmental agencies
in connection with the Reorganization, audit fees and legal fees
("Reorganization Costs"). The Acquiring Fund agrees to bear 25% of the
Reorganization Costs incurred in connection with each Reorganization. Amundi
Pioneer will bear the remaining 50% of the Reorganization Costs. Expenses will,
however, be paid by the party directly incurring the expenses to the extent
that the payment by another person would result in a failure by any fund to
qualify for treatment as a "regulated investment company" within the meaning of
Section 851 of the Internal Revenue Code or would prevent a Reorganization from
qualifying as a "reorganization" within the meaning of Section 368 of the
Internal Revenue Code or otherwise result in the imposition of tax on a fund or
on a fund's shareholders.

                       TAX STATUS OF THE REORGANIZATIONS

     Each Reorganization is conditioned upon the receipt by the applicable
Acquired Fund and the Acquiring Fund of an opinion from Morgan, Lewis & Bockius
LLP, counsel to the Pioneer Funds, substantially to the effect that, for
federal income tax purposes:

     o    The transfer to the Acquiring Fund of all of your fund's assets in
          exchange solely for the issuance of the Acquiring Fund's shares to
          your fund and the assumption of all of your fund's liabilities by the
          Trust, on behalf of the Acquiring Fund, followed by the distribution
          of the Acquiring Fund's shares to the shareholders of your fund in
          complete liquidation of your fund, will constitute a "reorganization"
          within the meaning of Section 368(a) of the Internal Revenue Code, and
          each of your fund and the Acquiring Fund will be a "party to a
          reorganization" within the meaning of Section 368(b) of the Internal
          Revenue Code;

     o    No gain or loss will be recognized by your fund in the Reorganization
          upon (1) the transfer of all of its assets to the Acquiring Fund and
          the assumption of all of its liabilities by the Acquiring Fund as
          described above or (2) the distribution by your fund of the Acquiring
          Fund's shares to your fund's shareholders in complete liquidation of
          your fund, except for (A) any gain or loss that may be recognized with
          respect to "section 1256 contracts" as defined in Section 1256(b) of
          the Internal Revenue Code, (B) any gain that may be recognized on the
          transfer of stock in a "passive foreign investment company" as defined
          in Section 1297(a) of the Internal Revenue Code, and (C) any other
          gain or loss that may be required to be recognized as a result of the
          closing of your fund's taxable year or upon the transfer of an asset
          regardless of whether such transfer would otherwise be a
          non-recognition transaction under the Internal Revenue Code;

     o    The tax basis in the hands of the Acquiring Fund of the assets of your
          fund transferred to the Acquiring Fund in the Reorganization will be
          the same as the tax basis of those assets in the hands of your fund
          immediately before the transfer of those assets, increased by the
          amount of gain (or decreased by the amount of loss), if any,
          recognized by your fund on the transfer;

     o    The holding period in the hands of the Acquiring Fund of each asset of
          your fund transferred to the Acquiring Fund in the Reorganization,
          other than assets with respect to which gain or loss is required to be
          recognized in the Reorganization, will include the period during which
          that asset was held by your fund (except where investment activities
          of the Acquiring Fund will have the effect of reducing or eliminating
          the holding period with respect to an asset);

     o    No gain or loss will be recognized by the Acquiring Fund upon its
          receipt of your fund's assets solely in exchange for shares of the
          Acquiring Fund and the assumption of your fund's liabilities as part
          of the Reorganization;

     o    You will not recognize gain or loss upon the exchange of your shares
          for shares of the Acquiring Fund as part of the Reorganization;

     o    The aggregate tax basis of the Acquiring Fund shares you receive in
          the Reorganization will be the same as the aggregate tax basis of the
          shares of your fund that you surrender in the exchange; and

     o    The holding period of the Acquiring Fund shares you receive in the
          Reorganization will include the holding period of the shares of your
          fund that you surrender in the exchange, provided that you hold the
          shares of your fund as capital assets on the date of the exchange.

     In rendering such opinion, counsel shall rely upon, among other things,
certain facts, assumptions and representations of your fund and the Acquiring
Fund. The condition that each fund receives such an opinion may not be waived.

                                       42



     No tax ruling has been or will be received from the Internal Revenue
Service ("IRS") in connection with either Reorganization. An opinion of counsel
is not binding on the IRS or a court, and no assurance can be given that the
IRS would not assert, or a court would not sustain, a contrary position.

     Immediately prior to the applicable Reorganization, your fund is expected
to declare and pay a dividend, which, together with all previous dividends, is
intended to have the effect of distributing to your fund's shareholders all of
your fund's investment company taxable income (computed without regard to the
dividends-paid deduction), all of its net tax-exempt income, and all of its net
capital gain (after deduction of any available capital loss carryover) for
taxable years ending on or prior to the applicable Closing Date. The amounts of
such distributions are estimated as of July 31, 2017 to be as set forth in the
table below. The amounts set forth in the table below are estimates based on
each fund's income and capital gains expected to be realized as if its taxable
year ended on the Closing Date. Amounts actually distributed to shareholders
immediately prior to the Reorganization may be higher or lower than the amounts
set forth in the table below

Fund                                      Distribution Amount (per share)
--------------------------------------------------------------------------
Pioneer Solutions -- Conservative Fund    $0.10 of ordinary income
--------------------------------------------------------------------------
Pioneer Solutions -- Growth Fund          $0.29 of long-term capital gains
--------------------------------------------------------------------------
Pioneer Solutions -- Balanced Fund        <$0.01 of ordinary income
--------------------------------------------------------------------------

     Any such distributions will generally result in taxable income to you.

     The foregoing discussion is very general and does not take into account
any considerations that may apply to certain classes of taxpayers who are
subject to special circumstances, such as shareholders who are not citizens of
or residents of the United States, insurance companies, tax-exempt
organizations, financial institutions, dealers in securities or foreign
currencies, or persons who hold their shares as part of a straddle or
conversion transaction. You should consult your tax adviser for the particular
tax consequences to you of the transaction, including the applicability of any
state, local or foreign tax laws.

                                       44



               BUYING, EXCHANGING AND SELLING SHARES OF THE FUNDS

     The table below provides information regarding how to buy, exchange and
sell shares of the Pioneer Funds. The policies disclosed below apply to each
Pioneer Fund.



-------------------------------------------------------------------------------------------------------------------------------
                                              Buying, Exchanging and Selling Shares
-------------------------------------------------------------------------------------------------------------------------------
               
Buying shares     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 Amundi Pioneer, for your purchase of fund shares.
-------------------------------------------------------------------------------------------------------------------------------
Minimum initial   Your initial investment for Class A or Class C shares must be at least $1,000. Additional investments
investment        must be at least $100 for Class A shares and $500 for Class C shares. The initial investment for 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 for Class Y
                  shares. There is no minimum investment amount for Class R 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 for, among other things, share purchases made through certain mutual fund programs
                  (e.g., asset based fee program accounts) sponsored by qualified intermediaries, such as broker-dealers
                  and investment advisers, that have entered into an agreement with Amundi Pioneer.
-------------------------------------------------------------------------------------------------------------------------------
Maximum purchase  Purchases of each Pioneer Fund shares are limited to $499,999 for Class C shares. These limits are
amounts           applied on a per transaction basis. There is no maximum purchase for Class A, Class R or Class Y shares.
-------------------------------------------------------------------------------------------------------------------------------
Exchanging shares 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 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.
-------------------------------------------------------------------------------------------------------------------------------
Selling shares    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. Each Pioneer Fund generally will send your sale proceeds by check, bank wire or electronic
                  funds transfer. Your redemption proceeds normally will be sent within 1 business day after your request
                  is received in good order, but in any event within 7 days, regardless of the method the Pioneer Fund uses
                  to make such payment. If you recently sent a check to purchase the shares being sold, the Pioneer 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.

                  Your redemption proceeds may be delayed, or your right to receive redemption proceeds suspended, if
                  the New York Stock Exchange is closed (other than on weekends or holidays) or trading is restricted, if
                  the Securities and Exchange Commission determines an emergency or other circumstances exist that
                  make it impracticable for a Pioneer 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.

-----------------------------------------------------------------------------------------------------------------------------
                                             Buying, Exchanging and Selling Shares
-----------------------------------------------------------------------------------------------------------------------------
              
                 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.

                 Under normal circumstances, a Pioneer Fund expects to meet redemption requests by using cash or cash
                 equivalents in its portfolio and/or selling portfolio assets to generate cash. Each Pioneer Fund also may
                 pay redemption proceeds using cash obtained through a committed, unsecured revolving credit facility,
                 an interfund lending facility, and other borrowing arrangements that may be available from time to time.

                 Each Pioneer Fund reserves the right to redeem in kind, that is, to pay all or a portion of your redemption
                 proceeds by giving you securities. 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. Each Pioneer Fund may redeem in kind at a shareholder's request or, for
                 example, if the Pioneer Fund reasonably believes that a cash redemption may have a substantial impact
                 on the Pioneer Fund and its remaining shareholders. During periods of stressed market conditions, a
                 Pioneer Fund may be more likely to pay redemption proceeds by giving you securities.
-----------------------------------------------------------------------------------------------------------------------------
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 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. 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 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.

                 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.

                 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.


                                       46




----------------------------------------------------------------------------------------------------------------------------
                                             Buying, Exchanging and Selling Shares
----------------------------------------------------------------------------------------------------------------------------
              
                 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 Amundi 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 Amundi 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.

                 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.

                 ADDITIONAL INFORMATION ABOUT THE PIONEER FUNDS

Investment adviser

Amundi Pioneer Asset Management, Inc., as each fund's investment adviser (the
"Adviser"), selects the fund's investments and oversees the fund's operations.

Amundi Pioneer is an indirect wholly owned subsidiary of Amundi and Amundi's
wholly owned subsidiary, Amundi USA, Inc. Amundi, one of the world's largest
asset managers, is headquartered in Paris, France. As of September 30, 2017,
Amundi had more than $1.6 trillion in assets under management worldwide. As of

Fund without shareholder approval. Amundi Pioneer retains the ultimate
responsibility to oversee and recommend the hiring, termination and replacement
of any unaffiliated subadviser.

Distributor

Amundi Pioneer Distributor, Inc. is each Pioneer Fund's distributor. Each
Pioneer Fund compensates the distributor for its services. The distributor is
an affiliate of Amundi Pioneer. Prior to July 3, 2017, the funds' distributor
was named Pioneer Funds Distributor, Inc.

Disclosure of portfolio holdings

Each Pioneer Fund's policies and procedures with respect to the disclosure of
its portfolio securities are described in the fund's statement of additional
information.

Distribution and service arrangements
-------------------------------------

Distribution Plan

Each Pioneer Fund has adopted a distribution plan for its Class A, Class C and
Class R shares in accordance with Rule 12b-1 under the 1940 Act. Under each
plan, a Pioneer Fund pays distribution and service fees to the distributor.
Because these fees are an ongoing expense of a Pioneer 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.

                                       48



Class R shares service plan

Each Pioneer 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 Pioneer 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 Pioneer Fund.

Additional Payments to Financial Intermediaries

Your financial intermediary may receive compensation from a Pioneer Fund,
Amundi Pioneer or 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.

Amundi Pioneer or 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 a Pioneer 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.

Amundi Pioneer or its affiliates make 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 a Pioneer
Fund, or from the retention of a portion of sales charges or distribution and
service fees. Amundi Pioneer may 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. Amundi 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 Amundi Pioneer's
promotional efforts. Amundi 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.

Amundi 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 Amundi 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, Amundi 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 Amundi Pioneer pays to financial intermediaries is
discussed in more detail in a Pioneer 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 Amundi Pioneer or the Pioneer
funds, as well as about fees and/or commissions it charges.

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

Choosing a Class of Shares
--------------------------

     See "Classes of Shares of the Funds" for information regarding the
characteristics and fee structure of Class A, Class C, Class R and Class Y
shares of the Pioneer Funds.

     Each class has different eligibility requirements, sales charges and
expenses, allowing you to choose the class that best meets your needs.

                                       49



     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.

For information on each Pioneer Fund's expenses, please see "Comparison of Fees
and Expenses." The availability of certain sales charge waivers and discounts
may depend on whether you purchase your shares directly from the fund or
through a financial intermediary. Specific intermediaries may have different
policies and procedures regarding the availability of front-end sales charge
waivers or contingent deferred (back-end) sales charge (CDSC) waivers, which
are discussed under "Intermediary defined sales charge waiver policies." In all
instances, it is the purchaser's responsibility to notify the fund or the
purchaser's financial intermediary at the time of purchase of any relationship
or other facts qualifying the purchaser for sales charge waivers or discounts.
For waivers and discounts not available through a particular intermediary,
shareholders will have to purchase fund shares directly from the fund or
through another intermediary to receive these waivers or discounts. Please see
the "Intermediary defined sales charge waiver policies" section to determine
any sales charge discounts and waivers that may be available to you through
your financial intermediary.

Share class eligibility -- Class R shares
-----------------------------------------

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 IRAs that are rollovers from eligible retirement plans that
offered one or more Class R share Pioneer funds as investment options and to
individual 401(k) plans. Class R shares are not available to non-retirement
accounts, traditional or Roth IRAs, Coverdell Education Savings Accounts, SEPs,
SAR-SEPs, SIMPLE IRAs, individual 403(b)s and most individual retirement
accounts or retirement plans that are not subject to the Employee Retirement
Income Security Act of 1974 (ERISA).

Initial Sales Charge (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 a Pioneer Fund.



                                Sales Charges for Class A Shares

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


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 Pioneer Fund shares may
be higher or lower due to rounding.

                                       50



Reduced sales charges -- Class A shares

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." Amundi 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 $50,000 (Rights of accumulation)

     o    You plan to invest at least $50,000 over the next 13 months (Letter of
          intent)

The availability of certain sales charge waivers and discounts may depend on
whether you purchase your shares directly from a Pioneer Fund or through a
financial intermediary. Please see the "Intermediary defined sales charge
waiver policies" section for more information.

Rights of accumulation -- Class A shares only

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.

Letter of intent -- Class A shares only

You can use a letter of intent to qualify for reduced sales charges in two
situations:

     o    If you plan to invest at least $50,000 (excluding any reinvestment of
          dividends and capital gain distributions) in a Pioneer 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 a Pioneer 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 Pioneer 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. 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. Amundi
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
401(k) accounts, and custodial accounts, such as ESA, UGMA and UTMA accounts.

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 Amundi Pioneer or an
affiliate.

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

The availability of certain sales charge waivers and discounts may depend on
whether you purchase your shares directly from the fund or through a financial
intermediary. Please see the "Intermediary defined sales charge waiver
policies" section for more information.

                                       51



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 Amundi
          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 Amundi Pioneer serves as investment
          adviser (at the time of initial share purchase);

     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;

     o    Employees of Regions Financial Corporation and its affiliates (at the
          time of initial share purchase);

     o    Members of the immediate families of any of the persons above;

     o    Any trust, custodian, pension, profit sharing or other benefit plan of
          the foregoing persons;

     o    Insurance company separate accounts;

     o    Certain wrap accounts for the benefit of clients of investment
          professionals or other financial intermediaries adhering to standards
          established by the distributor;

     o    Other funds and accounts for which Amundi Pioneer or any of its
          affiliates serves as investment adviser or manager;

     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 Amundi 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 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 Amundi 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

                                       52



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 Amundi Pioneer on or before March 31, 2004).

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:

            o     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);

            o     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);

            o     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


                                       53



            o     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:

            o     A return of excess employee deferrals or contributions;

            o     A qualifying hardship distribution as described in the
                  Internal Revenue Code;

            o     Due to retirement or termination of employment;

            o     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.

The availability of certain sales charge waivers and discounts may depend on
whether you purchase your shares directly from the fund or through a financial
intermediary. Please see the "Intermediary defined sales charge waiver
policies" section for more information.

Buying, exchanging and selling shares
-------------------------------------

Opening your account

You may open an account by completing an account application and sending it to

Each Pioneer Fund is generally available for purchase in the United States,
Puerto Rico, Guam, American Samoa and the U.S. Virgin Islands. Except to the
extent otherwise permitted by the Pioneer Funds' distributor, the Pioneer Funds
will only accept accounts from U.S. citizens with a U.S. address (including an
APO or FPO address) or resident aliens with a U.S. address (including an APO or
FPO address) and a U.S. taxpayer identification number.

Identity verification

To help the government fight the funding of terrorism and money laundering
activities, federal law requires all financial institutions to obtain, verify
and record information that identifies each person who opens an account. When
you open an account, you will need to supply your name, address, date of birth,
and other information that will allow the fund to identify you.

A Pioneer Fund may close your account if we cannot adequately verify your
identity. The redemption price will be the net asset value on the date of
redemption.

Investing through financial intermediaries and retirement plans

If you invest in a Pioneer Fund through your financial intermediary or through
a retirement plan, the options and services available to you may be different
from those discussed in this Information Statement/Prospectus. Shareholders
investing through financial intermediaries, programs sponsored by financial
intermediaries and retirement plans may only purchase funds and classes of
shares that are available. When you invest through an account that is not in
your name, you generally may buy and sell shares and complete other
transactions only through the account. Ask your investment professional or
financial intermediary for more information.

Additional conditions may apply to your investment in a Pioneer Fund, and the
investment professional or intermediary may charge you a transaction-based,
administrative or other fee for its services. These conditions and fees are in
addition to those imposed by the Pioneer Fund and its affiliates. You should
ask your investment professional or financial intermediary about its services
and any applicable fees.

Share prices for transactions

If you place an order to purchase, exchange or sell shares that is received in
good order by a Pioneer Fund's transfer agent or an authorized agent by the
close of regular trading on the New York Stock Exchange (usually 4:00 p.m.
Eastern time), the share price for your transaction will be based on the net
asset value 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     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)

            --    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 a Pioneer Fund's shares within 30 calendar days of a
redemption. See "Excessive trading."

Buying, exchanging and selling shares
-------------------------------------

Buying

You may buy a Pioneer Fund's 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 Pioneer 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
Amundi Pioneer, for your purchase of shares of a Pioneer Fund.

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.

                                       55



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. A Pioneer Fund may waive the
initial or subsequent investment minimums. Minimum investment amounts may be
waived for, among other things, share purchases made through certain mutual
fund programs (e.g., asset based fee program accounts) sponsored by qualified
intermediaries, such as broker-dealers and investment advisers, that have
entered into an agreement with Amundi Pioneer.

Class R shares

There is no minimum investment amount for Class R shares, although investments
are subject to the Pioneer 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. A Pioneer Fund may waive the initial investment amount.

Waiver 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 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 Amundi 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 Amundi 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.

Maximum purchase amounts

Purchases of shares of a Pioneer Fund are limited to $499,999 for Class C
shares. This limit is applied on a per transaction basis. Class A, Class R and
Class Y shares are not subject to a maximum purchase amount.

Retirement plan accounts

You can purchase shares of a Pioneer Fund through tax-deferred retirement plans
for individuals, businesses and tax-exempt organizations.

Your initial investment for most types of retirement plan accounts must be at
least $250. Additional investments for most types of retirement plans must be
at least $100.

                                       56



You may not use the account application accompanying this prospectus to
establish an Amundi Pioneer retirement plan. You can obtain retirement plan
applications from your investment firm or by calling the Retirement Plans
Department at 1-800-622-0176.

How to buy shares

Through your investment firm

Normally, your investment firm will send your purchase request to the Pioneer
Funds' 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 Amundi Pioneer, for
your purchase of shares of a Pioneer Fund.

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 shares of the Pioneer Fund 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 shares of a Pioneer Fund for an existing fund account by
mailing a check to the fund. Make your check payable to the Pioneer 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 on a U.S. bank. Include in your purchase request the Pioneer 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 Y shares only)

If you have an existing (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 Pioneer 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

Instruct your bank to wire funds to:

Receiving Bank:         State Street Bank and Trust Company
                        225 Franklin Street
                        Boston, MA 02101
                        ABA Routing No. 011000028

For further credit to:  Shareholder Name
                        Existing Pioneer Account No.
                        [Name of Pioneer Fund]

The 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.

                                       57



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. Each Pioneer 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 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 shares of
another class. 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 Pioneer
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 shares of a
Pioneer Fund 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 shares of a Pioneer Fund by mailing or faxing a letter of
instruction to the fund. You can exchange shares of a Pioneer Fund directly
through the Pioneer 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

      o     A signature guarantee for each registered owner if the amount of the
            exchange is more than $500,000

      o     The name of the Pioneer 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 Pioneer 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.

                                       58



If the shares you are selling are subject to a deferred sales charge, it will
be deducted from the sale proceeds. Each Pioneer Fund generally will send your
sale proceeds by check, bank wire or electronic funds transfer. Your redemption
proceeds normally will be sent within 1 business day after your request is
received in good order, but in any event within 7 days, regardless of the
method the Pioneer Fund uses to make such payment. If you recently sent a check
to purchase the shares being sold, the Pioneer 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.

Your redemption proceeds may be delayed, or your right to receive redemption
proceeds suspended, if the New York Stock Exchange is closed (other than on
weekends or holidays) or trading is restricted, if the Securities and Exchange
Commission determines an emergency or other circumstances exist that make it
impracticable for a Pioneer 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.

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.

Under normal circumstances, a Pioneer Fund expects to meet redemption requests
by using cash or cash equivalents in its portfolio and/or selling portfolio
assets to generate cash. Each Pioneer Fund also may pay redemption proceeds
using cash obtained through a committed, unsecured revolving credit facility,
an interfund lending facility, and other borrowing arrangements that may be
available from time to time.

Each Pioneer Fund reserves the right to redeem in kind, that is, to pay all or
a portion of your redemption proceeds by giving you securities. 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. Each Pioneer Fund may redeem in kind at a shareholder's
request or, for example, if the Pioneer Fund reasonably believes that a cash
redemption may have a substantial impact on the Pioneer Fund and its remaining
shareholders. During periods of stressed market conditions, a Pioneer Fund may
be more likely to pay redemption proceeds by giving you securities.

How to sell shares

Through your investment firm

Normally, your investment firm will send your request to sell shares to the
Pioneer Funds' transfer agent. Consult your investment professional for more
information. Each Pioneer Fund has authorized the distributor to act as its
agent in the repurchase of fund shares from qualified investment firms. Each
Pioneer Fund reserves the right to terminate this procedure at any time.

By phone or online

If you have an eligible non-retirement account, you may sell up to $100,000 per
account per day by phone or online. You may sell shares of a Pioneer Fund held
in a retirement plan account by phone only if your account is an eligible IRA
(tax penalties may apply). You may not sell your shares by phone or online if
you have changed your address (for checks) or your bank information (for wires
and transfers) in the last 30 days.

You may receive your sale proceeds:

      o     By check, provided the check is made payable exactly as your account
            is registered

      o     By bank wire or by electronic funds transfer, provided the sale
            proceeds are being sent to your bank address of record

For Class Y shares, shareholders may sell up to $5 million per account per day
if the proceeds are directed to your bank account of record ($100,000 per
account per day if the proceeds are not directed to your bank account of
record).

                                       59



In writing, by mail or by fax

You can sell some or all of your shares of a Pioneer Fund by writing directly
to the Pioneer Fund only if your account is registered in your name. Include in
your request your name, the name of the Pioneer Fund, your fund account number,
the class of shares to be sold, the dollar amount or number of shares to be
sold and any other applicable requirements as described below. The transfer
agent will send the sale proceeds to your address of record unless you provide
other instructions. Your request must be signed by all registered owners and be
in good order.

The transfer agent will not process your request until it is received in good
order.

You may sell up to $100,000 per account per day by fax.

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

Account options

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

Telephone transaction privileges

If your account is registered in your name, you can buy, exchange or sell
shares of the Pioneer Funds 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. Each Pioneer 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 a Pioneer 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.

                                       60



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 transfer agent 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 Amundi 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. Each Pioneer 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.

Periodic investments

You can make periodic investments in a Pioneer Fund by setting up monthly bank
drafts, government allotments, payroll deductions, or an Automatic Investment
Plan. Periodic investments may be made only through U.S. banks. You may use a
periodic 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 a periodic investment plan.

Automatic Investment Plan (AIP)

If you establish an Automatic Investment Plan with Amundi Pioneer, the transfer
agent will make a periodic investment in shares of a Pioneer Fund 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 shares of a Pioneer Fund 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

Each Pioneer Fund offers three distribution options. Any shares of a Pioneer
Fund 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 a Pioneer
            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.

      (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 Pioneer Fund may
reinvest the amount in additional shares of the fund instead of sending a
check. Additional shares of the Pioneer Fund will be purchased at the
then-current net asset value.

                                       61



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)

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.

Shareholder services and policies
---------------------------------

Excessive trading

Frequent trading into and out of a Pioneer Fund can disrupt portfolio
management strategies, harm the Pioneer Fund's performance by forcing the
Pioneer 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 Pioneer 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. Each Pioneer 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 a Pioneer 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.

Each Pioneer Fund's Board of Trustees has adopted policies and procedures with
respect to frequent purchases and redemptions of fund shares by investors in
the Pioneer Fund. 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 a Pioneer Fund, we will ask the investor, broker or other
intermediary to

                                       62



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 shareholders of the Pioneer Fund.

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 a Pioneer Fund may be adversely affected.
Frequently, shares of a Pioneer Fund are held through omnibus accounts
maintained by financial intermediaries such as brokers and retirement plan
administrators, 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.

Each Pioneer Fund may reject a purchase or exchange order before its acceptance
or the issuance of shares. Each Pioneer 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 Pioneer Fund believes are requested on behalf of market timers. Each
Pioneer Fund reserves the right to reject any purchase or exchange request by
any investor or financial institution if the Pioneer 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 Pioneer Fund and its shareholders do not
incur any gain or loss as a result of a rejected order. Each Pioneer Fund may
impose further restrictions on trading activities by market timers in the
future.

To limit the negative effects of excessive trading, each Pioneer 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 a Pioneer Fund, that investor shall be prevented (or
"blocked") from purchasing shares of the Pioneer 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 plans, scheduled (Internal Revenue Code Section 72(t)
election) or mandatory (required minimum distribution) withdrawals from IRAs,
rebalancing transactions made through certain asset allocation or "wrap"
programs, transactions by insurance company separate accounts or transactions
by other funds that invest in the Pioneer Fund. This policy does not apply to
purchase or redemption transactions of less than $5,000 or to Pioneer U.S.
Government Money Market Fund or Pioneer Multi-Asset Ultrashort Income Fund.

We rely on financial intermediaries that maintain omnibus accounts to apply to
their customers either the Pioneer Funds' policy described above or the
intermediaries' own policies or restrictions designed to limit excessive
trading of shares of a Pioneer Fund. 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 a Pioneer Fund provided
that Amundi Pioneer, in its sole discretion, determines that the securities are
consistent with the Pioneer Fund's objective and policies and their acquisition
is in the best interests of the Pioneer Fund. If the Pioneer Fund accepts your
securities, they will be valued for purposes of determining the number of
shares of the Pioneer Fund 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 shares of the Pioneer Fund for cash in
an amount equal to the value of the shares of the Pioneer fund that you
purchase. Your broker may also impose a fee in connection with processing your
purchase of shares of a Pioneer Fund 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 transfer agent 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 a Pioneer
Fund's shares within 30 calendar days of redemption. See "Excessive trading."

                                       63



When you elect reinstatement, you are subject to the provisions outlined in the
selected the Pioneer Fund's prospectus, including the fund's minimum investment
requirement. Your sale proceeds will be reinvested in shares of the Pioneer
Fund at the Class A net asset value per share determined after the transfer
agent receives your written request for reinstatement. You may realize a gain
or loss for federal income tax purposes as a result of your sale of shares of a
Pioneer Fund, and special tax rules may apply if you elect reinstatement.
Consult your tax adviser for more information.

                                       64



Privacy

Each Pioneer Fund has a policy designed to protect the privacy of your personal
information. A copy of Amundi Pioneer's privacy notice was given to you at the
time you opened your account. Each Pioneer 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 Amundi 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 shares of a
            Pioneer Fund

      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.

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. A Pioneer Fund may accept other
forms of guarantee from financial intermediaries in limited circumstances.

Fiduciaries and corporations are required to submit additional documents to
sell shares of a Pioneer Fund.

Minimum account size

Each Pioneer Fund requires that you maintain a minimum account value of $500.
If you hold less than $500 in your account, each Pioneer 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 a Pioneer 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, Amundi 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 a Pioneer Fund by
telephone, you should communicate with the Pioneer Fund in writing.

Share certificates

The Pioneer Funds do 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

Each Pioneer Fund and the distributor reserve the right to:

      o     reject any purchase or exchange order for any reason, without prior
            notice

      o     charge a fee for exchanges or to modify, limit or suspend the
            exchange privilege at any time without notice. Each Pioneer 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

Each Pioneer Fund reserves the right to:

      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. A Pioneer 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

                                       65



Dividends, capital gains and taxes
----------------------------------

Dividends and capital gains

Each Pioneer Fund generally pays any distributions of net short- and long-term
capital gains in November.

Each Pioneer Fund generally pays dividends from any net investment income in
December.

Each Pioneer 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 a Pioneer Fund shortly before a dividend or other
distribution, 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 a Pioneer
Fund, whether you take the distributions in cash or reinvest them in additional
shares. For U.S. federal income tax purposes, distributions from a Pioneer
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 a Pioneer Fund's net short-term capital gains are generally
taxable as ordinary income. Other dividends are taxable either as ordinary
income or, in general, if paid from a Pioneer Fund's "qualified dividend
income" and if certain conditions, including holding period requirements, are
met by the Pioneer Fund and the shareholder, as qualified dividend income
taxable to noncorporate shareholders at U.S. federal income tax rates of up to
20%.

"Qualified dividend income" generally is income derived from dividends paid by
U.S. corporations or certain foreign corporations that are either incorporated
in a U.S. possession or eligible for tax benefits under certain U.S. income tax
treaties. In addition, dividends that a Pioneer Fund receives in respect of
stock of certain foreign corporations may be qualified dividend income if that
stock is readily tradable on an established U.S. securities market.

A portion of dividends received from a Pioneer Fund (but none of the Pioneer
Fund's capital gain distributions) may qualify for the dividends-received
deduction for corporations.

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

If a Pioneer 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 you receive as if you
received it in the year in which it was declared.

Sales and exchanges generally will be taxable transactions to shareowners. When
you sell or exchange Pioneer 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 applicable Pioneer 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 Pioneer 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 Pioneer Fund dividends
or other distributions or on sales or exchanges of Pioneer Fund shares.
However, in the case of Pioneer Fund shares held through a nonqualified
deferred compensation plan, Pioneer 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 applicable Pioneer Fund or effecting such sales or
exchanges.

                                       66



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

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

                  FORM OF AGREEMENT AND PLAN OF REORGANIZATION

      This AGREEMENT AND PLAN OF REORGANIZATION (the "Agreement") is made as of
the [ ] day of [ ], by and among Pioneer Asset Allocation Trust, a Delaware
statutory trust (the "Trust"), with its principal place of business at 60 State
Street, Boston, Massachusetts 02109, on behalf of the Acquiring Fund and each
Acquired Fund as set forth on Exhibit A attached hereto, and, solely for
purposes of paragraph 9.2 hereof, Amundi Pioneer Asset Management, Inc. ("Amundi
Pioneer" or the "Acquiring Fund Adviser"). The Acquiring Fund and the Acquired
Funds are sometimes referred to collectively herein as the "Funds" and
individually as a "Fund."

      WHEREAS, it is intended that each reorganization of an Acquired Fund
contemplated by this Agreement constitute a "reorganization" as defined in
Section 368(a) of the United States Internal Revenue Code of 1986, as amended
(the "Code"), and the Treasury Regulations thereunder. Each reorganization of an
Acquired Fund will consist of (1) the transfer of all of the assets of the
Acquired Fund to the Acquiring Fund solely in exchange for (A) the issuance of
Class A, Class C, Class R and Class Y shares of beneficial interest of the
Acquiring Fund (collectively, the "Acquiring Fund Shares" and each, an
"Acquiring Fund Share") to the Acquired Fund, and (B) the assumption by the
Acquiring Fund of all of the liabilities of the Acquired Fund on the closing
date of such reorganization (the "Closing Date"), and (2) the distribution by
the Acquired Fund, on or promptly after the Closing Date as provided herein, of
the Acquiring Fund Shares to the shareholders of the Acquired Fund, pro rata on
a class-by-class basis, in complete liquidation of the Acquired Fund, as
provided herein (each, a "Reorganization"), all upon the terms and conditions
hereinafter set forth in this Agreement. The parties hereby adopt this Agreement
as a "plan of reorganization" within the meaning of Treasury Regulations Section
1.368-2(g).

      WHEREAS, each of the Acquired Funds and the Acquiring Fund is a series of
the Trust, a registered investment company classified as management company of
the open-end type.

      WHEREAS, the Acquiring Fund is authorized to issue shares of beneficial
interest.

      WHEREAS, the Board of Trustees of the Trust has determined, with respect
to the Acquiring Fund and the Reorganization of each Acquired Fund, that such
Reorganization is in the best interests of the Acquiring Fund and its
shareholders and is not dilutive of the interests of those shareholders.

      WHEREAS, the Board of Trustees of the Trust has determined, with respect
to each Acquired Fund, that the Reorganization of such Acquired Fund is in the
best interests of such Acquired Fund and its shareholders and is not dilutive of
the interests of those shareholders.

      NOW, THEREFORE, in consideration of the premises of the covenants and
agreements hereinafter set forth, the parties hereto covenant and agree as
follows:

1.    TRANSFER OF ASSETS OF EACH ACQUIRED FUND IN EXCHANGE FOR ACQUIRING FUND
      SHARES AND ASSUMPTION OF ASSUMED LIABILITIES; LIQUIDATION AND TERMINATION
      OF THE ACQUIRED FUND.

      1.1 Subject to the terms and conditions herein set forth and on the basis
of the representations and warranties contained herein, each Acquired Fund will
transfer all of its assets as set forth in Paragraph 1.2 (the "Acquired Assets")
to the Acquiring Fund free and clear of all liens and encumbrances (other than
those arising under the Securities Act of 1933, as amended (the "Securities
Act"), liens for taxes not yet due and contractual restrictions on the transfer
of the Acquired Assets) and the Trust, on behalf of the Acquiring Fund, agrees
in exchange therefor: (i) to issue to such Acquired Fund the number of Acquiring
Fund Shares, including fractional Acquiring Fund Shares, of each class with an
aggregate net asset value ("NAV") equal to the aggregate NAV of such Acquired
Fund attributable to the corresponding class (determined as set forth in
Paragraph 1.4) of such Acquired Fund's shares, as determined in the manner set
forth in Paragraphs 2.1 and 2.2; and (ii) to assume all of the liabilities and
obligations of such Acquired Fund, whether accrued or contingent, known or
unknown, existing at the applicable Closing Date (collectively, the "Assumed
Liabilities"). Such transactions shall take place at the Closing (as defined in
Paragraph 3.1 below).

      1.2 (a) The Acquired Assets of each Acquired Fund shall consist of all of
the Acquired Fund's property, including, without limitation, all portfolio
securities and instruments, dividends and interest receivables, cash, goodwill,
contractual rights and choses in action of such Acquired Fund or the Trust in
respect of such Acquired Fund, all other intangible property owned by such
Acquired Fund, originals or copies of all books and records of such Acquired
Fund, and all other assets of the Acquired Fund on the applicable Closing Date.
The Acquiring Fund shall also be entitled to receive copies of all records that
such Acquired Fund is required to maintain under the Investment Company Act of
1940, as amended (the "Investment Company Act"), and the rules of the Securities
and Exchange Commission (the "Commission") promulgated thereunder to the extent
such records pertain to such Acquired Fund.

      (b) Each Acquired Fund has provided the Acquiring Fund with a list of all
of such Acquired Fund's securities and other assets as of the date of execution
of this Agreement, and the Acquiring Fund has provided such Acquired Fund with a
copy of the current fundamental investment policies and restrictions and fair
value procedures applicable to the Acquiring Fund. Such Acquired

                                      A-1



Fund reserves the right to sell any of such securities or other assets before
the applicable Closing Date (except to the extent sales may be limited by
representations of such Acquired Fund contained herein or may be inconsistent
with the Acquired Fund Tax Representation Certificate (as defined below) to be
delivered in connection with the issuance of the tax opinion provided for in
Paragraph 8.4 hereof) and agrees not to acquire any portfolio security that is
not an eligible investment for, or that would violate an investment policy or
restriction of, the Acquiring Fund.

      1.3 Each Acquired Fund will endeavor to discharge all of its known
liabilities and obligations that are or will become due prior to the Closing.

      1.4 Immediately following the actions contemplated by paragraph 1.1 with
respect to an Acquired Fund, the Trust, on behalf of the Acquired Fund, shall
take such actions as may be necessary or appropriate to complete the liquidation
of the Acquired Fund. To complete the liquidation of an Acquired Fund, the
Trust, on behalf of the Acquired Fund, shall, on or as soon after the applicable
Closing Date as is practicable (the "Liquidation Date"), liquidate the Acquired
Fund, and distribute pro rata on a class-by-class basis to its shareholders of
record, determined as of the close of regular trading on the New York Stock
Exchange on the applicable Closing Date (the "Acquired Fund Shareholders"), the
Acquiring Fund Shares received by the Acquired Fund pursuant to Paragraph 1.1
hereof. Each Acquired Fund Shareholder of that Acquired Fund shall receive the
number of full and fractional Acquiring Fund Shares of each class corresponding
to a class of shares of beneficial interest in that Acquired Fund (the "Acquired
Fund Shares") held by such Acquired Fund Shareholder that has, in each case, an
aggregate NAV equal to the aggregate NAV of the Acquired Fund Shares of the
applicable class held of record by such Acquired Fund Shareholder on the
applicable Closing Date. Acquired Fund Shareholders shall receive Class A, Class
C, Class R and Class Y Acquiring Fund Shares in exchange for Class A, Class C,
Class R and Class Y Acquired Fund Shares, respectively. Such liquidation and
distribution will be accomplished by the Acquired Fund instructing the Acquiring
Fund to transfer the Acquiring Fund Shares then credited to the account of the
Acquired Fund on the books of the Acquiring Fund to open accounts on the share
records of the Acquiring Fund established and maintained by the Acquiring Fund's
transfer agent in the names of the Acquired Fund Shareholders of that Acquired
Fund and representing the respective numbers of the Acquiring Fund Shares of
each class due to each such Acquired Fund Shareholder. The Acquired Fund shall
promptly provide the Acquiring Fund with evidence of such liquidation and
distribution. All issued and outstanding Acquired Fund Shares of that Acquired
Fund will simultaneously be cancelled on the books of the Acquired Fund, and the
Acquired Fund will be dissolved. The Acquiring Fund shall not issue certificates
representing the Acquiring Fund Shares in connection with such exchange.

      1.5 Ownership of Acquiring Fund Shares will be shown on the books of the
Acquiring Fund's transfer agent. Any certificates representing ownership of
Acquired Fund Shares that remain outstanding on the applicable Closing Date
shall be deemed to be cancelled and shall no longer evidence ownership of
Acquired Fund Shares.

      1.6 Any transfer taxes payable upon issuance of Acquiring Fund Shares in a
name other than the registered holder of the Acquired Fund Shares on the books
of an Acquired Fund as of that time shall, as a condition of such issuance and
transfer, be paid by the person to whom such Acquiring Fund Shares are to be
issued and transferred.

      1.7 Any reporting responsibility of the Trust with respect to an Acquired
Fund for periods ending on or before the applicable Closing Date, including, but
not limited to, the responsibility for filing of regulatory reports, or other
documents with the Commission, any state securities commissions, and any
federal, state or local tax authorities or any other relevant regulatory
authority, is and shall remain the responsibility of such Acquired Fund.

2. VALUATION

      2.1 The NAV per share of each class of the Acquiring Fund Shares and the
NAV per share of each class of an Acquired Fund shall, in each case, be
determined as of the close of regular trading on the New York Stock Exchange
(generally, 4:00 p.m., Eastern time) on the applicable Closing Date (the
"Valuation Time"). The Acquiring Fund Adviser shall compute the NAV per
Acquiring Fund Share in the manner set forth in the Trust's Agreement and
Declaration of Trust (the "Declaration"), or By-Laws, and the Acquiring Fund's
then-current prospectus and statement of additional information. The Acquiring
Fund Adviser shall compute the NAV per share of an Acquired Fund in the manner
set forth in the Declaration, or By-Laws, and that Acquired Fund's then-current
prospectus and statement of additional information. The Acquiring Fund Adviser
shall confirm to the Acquiring Fund the NAV of that Acquired Fund.

      2.2 The number of shares of each class of Acquiring Fund Shares to be
issued (including fractional shares, if any) in exchange for the Acquired Assets
of an Acquired Fund (taking into account the assumption of the Assumed
Liabilities of that Acquired Fund) shall be determined by the Acquiring Fund
Adviser by dividing the NAV of that Acquired Fund attributable to each class of
the Acquired Fund Shares of that Acquired Fund, as determined in accordance with
Paragraph 2.1, by the NAV of an Acquiring Fund Share of the corresponding class,
as determined in accordance with Paragraph 2.1.

                                      A-2



      2.3 With respect to each Reorganization, the Acquiring Fund and applicable
Acquired Fund shall cause the Acquiring Fund Adviser to deliver a copy of its
valuation report to the other party at the applicable Closing (as defined in
Paragraph 3.1). All computations of value shall be made by the Acquiring Fund
Adviser or its agents in accordance with its regular practice as pricing agent
for the Acquiring Fund and such Acquired Fund.

3. CLOSING AND CLOSING DATE

      3.1 The Closing Date for each Reorganization shall be [ ], or, as to
either Reorganization, such other earlier or later date as the parties may
agree. All acts necessary to consummate a Reorganization (the "Closing") shall
be deemed to take place simultaneously as of 5:00 p.m. (Eastern time) on the
Closing Date unless otherwise agreed by the parties. Each Closing shall be held
at the offices of Morgan, Lewis & Bockius LLP, One Federal Street, Boston,
Massachusetts, or at such other place as the parties may agree. Neither
Reorganization is contingent upon the closing of the other Reorganization, and
the failure of one Reorganization to be consummated shall not, without more,
excuse the consummation of the other Reorganization.

      3.2 Any portfolio securities that are held other than in book-entry form
in the name of Brown Brothers Harriman & Co. (the "Acquired Fund Custodian") as
record holder for an Acquired Fund shall be presented by that Acquired Fund to
Brown Brothers Harriman & Co. (the "Acquiring Fund Custodian") for examination
no later than three (3) business days preceding the applicable Closing Date.
Such portfolio securities shall be delivered by the applicable Acquired Fund to
the Acquiring Fund Custodian for the account of the Acquiring Fund on the
applicable Closing Date, duly endorsed in proper form for transfer, in such
condition as to constitute good delivery thereof in accordance with the custom
of brokers, and shall be accompanied by all necessary federal and state stock
transfer stamps or a check for the appropriate purchase price thereof. Any
portfolio securities held of record by the Acquired Fund Custodian in book-entry
form on behalf of an Acquired Fund shall be delivered by the Acquired Fund
Custodian through the Depository Trust Company to the Acquiring Fund Custodian
and by the Acquiring Fund Custodian recording the beneficial ownership thereof
by the Acquiring Fund on the Acquiring Fund Custodian's records. Any cash shall
be delivered by the Acquired Fund Custodian transmitting immediately available
funds by wire transfer to the Acquiring Fund Custodian the cash balances
maintained by the Acquired Fund Custodian and the Acquiring Fund Custodian
crediting such amount to the account of the Acquiring Fund.

      3.3 With respect to each Reorganization, the Acquiring Fund Custodian
shall deliver within one business day after the applicable Closing a certificate
of an authorized officer stating that the Acquired Assets have been delivered in
proper form to the Acquiring Fund on the applicable Closing Date. The applicable
Acquired Fund shall deliver within one business day after the applicable Closing
a certificate of an authorized officer stating that all necessary transfer taxes
including all applicable federal and state stock transfer stamps, if any, have
been paid, or provision for payment has been made in conjunction with the
delivery of portfolio securities as part of the Acquired Assets.

      3.4 If on the Closing Date of a Reorganization (a) the New York Stock
Exchange is closed to trading or trading thereon shall be restricted or (b)
trading or the reporting of trading on such exchange or elsewhere is disrupted
so that accurate appraisal of the NAV of the Acquiring Fund Shares or the
applicable Acquired Fund pursuant to Paragraph 2.1 is impracticable (in the
judgment of the Board of the Trust with respect to the Acquiring Fund and such
Acquired Fund), the Closing Date of that Reorganization shall be postponed until
the first business day after the day when trading shall have been fully resumed
and reporting shall have been restored or such later date as may be mutually
agreed in writing by an authorized officer of each party.

      3.5 With respect to each Reorganization, the Acquired Fund shall deliver
at the applicable Closing a list of the names, addresses, federal taxpayer
identification numbers and U.S. federal tax withholding statuses of the Acquired
Fund Shareholders of that Acquired Fund (and any certificates reflecting that
information) and the number and percentage ownership of outstanding Acquired
Fund Shares of that Acquired Fund owned by each Acquired Fund Shareholder of
that Acquired Fund as of the Valuation Time, certified by the President or Vice
President or a Secretary or Assistant Secretary of the Trust and its Treasurer,
Secretary or other authorized officer (the "Shareholder List") as being an
accurate record of the information (a) provided by the Acquired Fund
Shareholders, (b) provided by the Acquired Fund Custodian, or (c) derived from
the Trust's records by such officers or one of the Trust's service providers.
The Acquiring Fund shall issue and deliver to the applicable Acquired Fund a
confirmation evidencing the Acquiring Fund Shares to be credited on the
applicable Closing Date, or provide evidence satisfactory to the Acquired Fund
that such Acquiring Fund Shares have been credited to the Acquired Fund's
account on the books of the Acquiring Fund. At the applicable Closing, each
party shall deliver to the other such bills of sale, checks, assignments, stock
certificates, receipts or other documents as such other party or its counsel may
reasonably request.

4. REPRESENTATIONS AND WARRANTIES

      4.1 Except as set forth on Schedule 4.1 of this Agreement, the Trust, on
behalf of each Acquired Fund, severally but not jointly, represents, warrants
and covenants to the Acquiring Fund with respect to that Acquired Fund as

       (a) Such Acquired Fund is a series of the Trust. The Trust is a
statutory trust validly existing and in good standing under the laws of the
State of Delaware and has the power to own all of its properties and assets and
to perform its obligations under this Agreement. Such Acquired Fund is not

or disability. Such Acquired Fund has all necessary federal, state and local
authorizations to own all of its properties and assets and to carry on its
business as now being conducted;

      (b) The Trust is a registered investment company classified as a
management company of the open-end type, and its registration with the
Commission as an investment company under the Investment Company Act is in full
force and effect;

      (c) The Trust is not in violation of, and the execution and delivery of
this Agreement and the performance of its obligations under this Agreement on
behalf of such Acquired Fund will not result in a material violation of, any
provision of the Trust's Declaration or By-Laws or any material agreement,
indenture, instrument, contract, lease or other undertaking with respect to such
Acquired Fund to which the Trust, on behalf of such Acquired Fund, is a party or
by which such Acquired Fund or any of its assets are bound;

      (d) No litigation or administrative proceeding or investigation of or
before any court or governmental body is currently pending or to its knowledge
threatened against such Acquired Fund or any of such Acquired Fund's properties
or assets that, if adversely determined, would materially and adversely affect
its financial condition or the conduct of such Acquired Fund's business. Such
Acquired Fund is not a party to or subject to the provisions of any order,
decree or judgment of any court or governmental body which materially adversely
affects such Acquired Fund's business or its ability to consummate the
transactions contemplated herein or would be binding upon the Acquiring Fund as
the successor to such Acquired Fund;

      (e) All material contracts or other commitments of such Acquired Fund
(other than this Agreement or agreements for the purchase and sale of securities
entered into in the ordinary course of business and consistent with its
obligations under this Agreement) will terminate at or prior to the applicable
Closing Date and no such termination will result in liability to such Acquired
Fund (or the Acquiring Fund);

      (f) The Statement of Assets and Liabilities of such Acquired Fund, and the
related Statements of Operations and Changes in Net Assets, as of and for the
fiscal year ended July 31, 2017, have been audited by Ernst & Young LLP,
independent registered public accounting firm, and are in accordance with
generally accepted accounting principles ("GAAP") consistently applied and
fairly reflect, in all material respects, the financial condition of such
Acquired Fund as of such date and the results of its operations for the period
then ended, and all known liabilities, whether actual or contingent, of such
Acquired Fund as of the date thereof are disclosed therein. Except for the
Assumed Liabilities, such Acquired Fund will not have any known or contingent
liabilities on the applicable Closing Date. No significant deficiency, material
weakness, fraud, significant change or other factor that could significantly
affect the internal controls of such Acquired Fund has been disclosed or is
required to be disclosed in such Acquired Fund's reports on Form N-CSR to enable
the chief executive officer and chief financial officer or other officers of the
Trust to make the certifications required by the Sarbanes-Oxley Act, and no

respect to such Acquired Fund that will be required to be disclosed in the
Acquiring Fund's Form N-CSR after the applicable Closing Date;

      (g) Since the most recent fiscal year end, except as specifically
disclosed in such Acquired Fund's prospectus or its statement of additional

material adverse change in such Acquired Fund's financial condition, assets,
liabilities, business or prospects, or any incurrence by such Acquired Fund of
indebtedness, except for normal contractual obligations incurred in the ordinary
course of business or in connection with the settlement of purchases and sales
of portfolio securities. For the purposes of this subparagraph (g) (but not for
any other purpose of this Agreement), a decline in NAV per Acquired Fund Share
arising out of its normal investment operations or a decline in market values of
securities in such Acquired Fund's portfolio, a decline in net assets of such
Acquired Fund as a result of redemptions or the discharge of Acquired Fund
liabilities shall not constitute a material adverse change;

      (h) On the applicable Closing Date, all federal and other tax returns,
dividend reporting forms and other tax-related reports of such Acquired Fund
required by law to have been filed (taking into account any extensions) shall
have been timely filed (taking such extensions into account) and shall be
correct in all material respects, and all federal and other taxes shown as due
or required to be shown as due from such Acquired Fund on such tax returns,
forms and reports shall have been timely paid or provision shall have been made
for the payment thereof and, to the best of the Trust's knowledge, no such tax
return is currently under audit and no outstanding assessment of any tax has
been asserted with respect to such returns;

      (i) Such Acquired Fund is a separate series of the Trust treated as a
separate corporation from each other series of the Trust under Section 851(g) of
the Code. For each taxable year of its existence, including the taxable year
ending on the applicable Closing Date, such Acquired Fund has had in effect an
election to be treated as a "regulated investment company" under Subchapter M of
the Code, has satisfied or will satisfy all of the requirements of Subchapter M
of the Code for treatment as a regulated

                                      A-4



investment company, and has been or will be eligible to compute its federal

Section 561 of the Code, substantially all of (a) the sum of (i) its net
tax-exempt interest income, (ii) its investment company taxable income (as
defined in the Code, computed without regard to any deduction for dividends
paid) and (iii) any net capital gain (as such term is used in Sections
852(b)(3)(A) and (C) of the Code) after reduction by any available capital loss
carryforwards, and (b) any other amounts as are necessary, in each case for all
of its tax periods ending on or before the applicable Closing Date, such that
such Acquired Fund will have no unpaid tax liability under Section 852 of the
Code for any tax period ending on or before the applicable Closing Date. For
each calendar year (including the calendar year that includes the applicable
Closing Date), such Acquired Fund will have made such distributions on or
before the applicable Closing Date as are necessary so that for all calendar
years ending on or before the applicable Closing Date, and for the calendar
year that includes the applicable Closing Date, such Acquired Fund will not
have any unpaid tax liability under Section 4982 of the Code;

      (j) All issued and outstanding Acquired Fund Shares of such Acquired Fund
are, and at the applicable Closing Date will be, legally issued and outstanding,
fully paid and nonassessable by such Acquired Fund. All of the issued and
outstanding Acquired Fund Shares of such Acquired Fund will, at the time of
Closing of the Reorganization of such Acquired Fund, be held of record by the
persons and in the amounts set forth in the Shareholder List submitted to such
Acquiring Fund pursuant to Paragraph 3.5 hereof. Such Acquired Fund does not
have outstanding any options, warrants or other rights to subscribe for or
purchase any Acquired Fund Shares of such Acquired Fund, nor is there
outstanding any security convertible into any Acquired Fund Shares of such
Acquired Fund;

      (k) At the applicable Closing Date, such Acquired Fund will have good and
marketable title to the Acquired Assets of such Acquired Fund, and full right,
power and authority to sell, assign, transfer and deliver the Acquired Assets of
such Acquired Fund to the Acquiring Fund, and, upon delivery and payment for the
Acquired Assets of such Acquired Fund, the Acquiring Fund will acquire good and
marketable title thereto, subject to no restrictions on the full transfer
thereof, except such restrictions as might arise under the Securities Act;

      (l) The Trust has the trust power and authority, on behalf of such
Acquired Fund, to enter into and perform its obligations under this Agreement.
The execution, delivery and performance of this Agreement have been duly
authorized by all necessary action on the part of the Trust's Board of Trustees,
and, assuming due authorization, execution and delivery by the Trust, on behalf
of the Acquiring Fund, this Agreement will constitute a valid and binding
obligation of the Trust, on behalf of such Acquired Fund, enforceable in
accordance with its terms, subject as to enforcement, to bankruptcy, insolvency,

      4.2 Except as set forth on Schedule 4.2 of this Agreement, the Trust, on
behalf of the Acquiring Fund, represents, warrants and covenants to each
Acquired Fund, as follows:

      (a) The Acquiring Fund is a series of the Trust. The Trust is a statutory
trust validly existing and in good standing under the laws of the State of
Delaware. The Trust has the power to own all of its properties and assets and to
perform its obligations under this Agreement. The Acquiring Fund is not required
to qualify to do business in any jurisdiction in which it is not so qualified or
where failure to qualify would subject it to any material liability or
disability. The Acquiring Fund has all necessary federal, state and local
authorizations to own all of its properties and assets and to carry on its
business as now being conducted;

      (b) The Trust is a registered investment company classified as a
management company of the open-end type, and its registration with the
Commission as an investment company under the Investment Company Act is in full
force and effect;

      (c) The current prospectus and statement of additional information of the
Acquiring Fund and any amendment or supplement thereto, conform or conformed at
the time of their distribution to the public in all material respects to the
applicable requirements of the Securities Act and the Investment Company Act and
the rules and regulations of the Commission promulgated thereunder and do not or
did not at the time of their distribution to the public include any untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary to make the statements therein, in light of the
circumstances under which they were made, not materially misleading;

      (d) The Trust's registration statement on Form N-1A with respect to the
Acquiring Fund that will be in effect on the applicable Closing Date, and the
prospectus and statement of additional information of the Acquiring Fund
included therein, will conform in all material respects with the applicable
requirements of the Securities Act and the Investment Company Act and the rules
and regulations of the Commission thereunder, and did not as of the effective
date thereof and will not as of the applicable Closing Date contain any untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary to make the statements therein, in light of the
circumstances in which they were made, not misleading;

                                      A-6

       (e) The Trust is not in violation of, and the execution and
delivery of this Agreement and performance of its obligations under this
Agreement on behalf of the Acquiring Fund will not result in a material
violation of, any provisions of the Declaration or By-Laws of the Trust or any
material agreement, indenture, instrument, contract, lease or other undertaking
with respect to the Acquiring Fund to which the Trust, on behalf of the
Acquiring Fund, is a party or by which the Acquiring Fund or any of its assets
is bound;

      (f) No litigation or administrative proceeding or investigation of or
before any court or governmental body is currently pending or to its knowledge
threatened against the Acquiring Fund or any of the Acquiring Fund's properties
or assets that, if adversely determined, would materially and adversely affect
its financial condition or the conduct of the Acquiring Fund's business. Neither
the Trust nor the Acquiring Fund is a party to or subject to the provisions of
any order, decree or judgment of any court or governmental body which materially
adversely affects the Acquiring Fund's business or its ability to consummate the
transactions contemplated herein;

      (g) The Statement of Assets and Liabilities of the Acquiring Fund, and the
related Statements of Operations and Changes in Net Assets, as of and for the
fiscal year ended July 31, 2017 have been audited by Ernst & Young LLP,
independent registered public accounting firm, and are in accordance with GAAP
consistently applied and fairly reflect, in all material respects, the financial
condition of the Acquiring Fund as of such date and the results of its
operations for the period then ended, and all known liabilities, whether actual
or contingent, of the Acquiring Fund as of the date thereof are disclosed
therein;

      (h) Since the most recent fiscal year end, except as specifically
disclosed in the Acquiring Fund's prospectus or its statement of additional
information as in effect on the date of this Agreement, there has not been any
material adverse change in the Acquiring Fund's financial condition, assets,
liabilities, business or prospects, or any incurrence by the Acquiring Fund of
indebtedness, except for normal contractual obligations incurred in the ordinary
course of business or in connection with the settlement of purchases and sales
of portfolio securities. For the purposes of this subparagraph (h) (but not for
any other purpose of this Agreement), a decline in NAV per Acquiring Fund Share
arising out of its normal investment operations or a decline in market values of
securities in the Acquiring Fund's portfolio, a decline in net assets of the
Acquiring Fund as a result of redemptions or the discharge of Acquiring Fund
liabilities shall not constitute a material adverse change;

      (i) On the applicable Closing Date, all federal and other tax returns,
dividend reporting forms and other tax-related reports of the Acquiring Fund
required by law to have been filed (taking into account any extensions) shall
have been timely filed (taking such extensions into account) and shall be
correct in all material respects, and all federal and other taxes shown as due
or required to be shown as due from the Acquiring Fund on such tax returns,
forms and reports shall have been timely paid or provision shall have been made
for the payment thereof and, to the best of the Trust's knowledge, no such tax
return is currently under audit and no outstanding assessment of any tax has
been asserted with respect to such returns;

      (j) The Acquiring Fund is a separate series of the Trust treated as a
separate corporation from each other series of the Trust under Section 851(g) of
the Code. For each taxable year of its existence ending on or before the
applicable Closing Date, the Acquiring Fund has had in effect an election to be
treated as a "regulated investment company" under Subchapter M of the Code, has
satisfied or will satisfy all of the requirements of Subchapter M of the Code
for treatment as a regulated investment company, and has been or will be
eligible to compute its federal income tax under Section 852 of the Code. On or
before the applicable Closing Date, the Acquiring Fund will have declared and
paid dividends sufficient to distribute, as dividends qualifying for the
dividends-paid deduction under Section 561 of the Code, substantially all of (a)
the sum of (i) its net tax-exempt interest income, (ii) its investment company
taxable income (as defined in the Code, computed without regard to any deduction
for dividends paid) and (iii) its net capital gain (as such term is used in
Sections 852(b)(3)(A) and (C) of the Code), if any, after reduction by any
available capital loss carryforwards, and (b) any other amounts as are
necessary, in each case for all of its tax periods ending on or before the
applicable Closing Date, such that the Acquiring Fund will have no unpaid tax
liability under Section 852 of the Code for any tax period ending on or before
the applicable Closing Date. For each calendar year ending on or before the
applicable Closing Date, the Acquiring Fund will have made such distributions on
or before the applicable Closing Date as are necessary so that for all calendar
years ending on or before the applicable Closing Date the Acquiring Fund will
not have any unpaid tax liability under Section 4982 of the Code. The Acquiring
Fund expects to satisfy the requirements of Subchapter M of the Code for
treatment as a regulated investment company and to be eligible for such
treatment for its taxable year that includes the applicable Closing Date;


      (k) The authorized capital of the Acquiring Fund consists of an unlimited
number of shares of beneficial interest, no par value per share. As of the
applicable Closing Date, the Acquiring Fund will be authorized to issue an
unlimited number of shares of beneficial interest, no par value per share. The
Acquiring Fund Shares to be issued and delivered to the Acquired Fund for the
account of the Acquired Fund Shareholders pursuant to the terms of this
Agreement will have been duly authorized on the applicable

                                      A-7



Closing Date and, when so issued and delivered, will be legally issued and
outstanding, fully paid and non-assessable. The Acquiring Fund does not have
outstanding any options, warrants or other rights to subscribe for or purchase
any Acquiring Fund Shares, nor is there outstanding any security convertible
into any Acquiring Fund Shares;

      (l) All issued and outstanding Acquiring Fund Shares are, and on the
applicable Closing Date will be, legally issued, fully paid and non-assessable
and have been offered and sold in every state and the District of Columbia in
compliance in all material respects with all applicable federal and state
securities laws;

      (m) The Trust has the trust power and authority, on behalf of the
Acquiring Fund, to enter into and perform its obligations under this Agreement.
The execution, delivery and performance of this Agreement have been duly
authorized by all necessary action on the part of the Trust's Board of Trustees,
and, assuming due authorization, execution and delivery by the Trust, on behalf
of an Acquired Fund, this Agreement will constitute a valid and binding
obligation of the Trust, on behalf of the Acquiring Fund, with respect to that
Acquired Fund, enforceable in accordance with its terms, subject as to
enforcement, to bankruptcy, insolvency, reorganization, moratorium and other
laws relating to or affecting creditors' rights and to general equity
principles;

      (n) The information to be furnished in writing by the Trust, on behalf of
the Acquiring Fund, for use in applications for orders, registration statements
and other documents which may be necessary in connection with the transactions
contemplated hereby shall be accurate and complete in all material respects and
shall comply in all material respects with federal securities and other laws and
regulations applicable thereto or the requirements of any form for which its use
is intended, and shall not contain any untrue statement of a material fact or
omit to state a material fact necessary to make the information provided not
misleading;

      (o) No consent, approval, authorization or order of or filing with any
court or governmental authority is required for the execution of this Agreement
or the consummation of the transactions contemplated by this Agreement by the
Trust or the Acquiring Fund, except such as may be required under the Securities
Act, the Exchange Act, the Investment Company Act and the rules and regulations
of the Commission thereunder, state securities laws and the Hart-Scott-Rodino
Act;

      (p) The Acquiring Fund currently complies in all material respects with,
the requirements of, and the rules and regulations under, the Investment Company
Act, the Securities Act, the Exchange Act, state "Blue Sky" laws and all other
applicable federal and state laws or regulations. The Acquiring Fund currently
complies in all material respects with all investment objectives, policies,
guidelines and restrictions and any compliance procedures established by the
Trust with respect to the Acquiring Fund. All advertising and sales material
currently used by the Acquiring Fund complies in all material respects with the
applicable requirements of the Securities Act, the Investment Company Act, the
rules and regulations of the Commission, and, to the extent applicable, the
Conduct Rules of FINRA and any applicable state regulatory authority. All
registration statements, prospectuses, reports, proxy materials or other filings
required to be made or filed with the Commission, FINRA or any state securities
authorities used by the Acquiring Fund during the three (3) years prior to the
date of this Agreement have been duly filed and have been approved or declared
effective, if such approval or declaration of effectiveness is required by law.
Such registration statements, prospectuses, reports, proxy materials and other
filings under the Securities Act, the Exchange Act and the Investment Company
Act (i) are or were in compliance in all material respects with the requirements
of all applicable statutes and the rules and regulations thereunder and (ii) do
not or did not contain any untrue statement of a material fact or omit to state
a material fact required to be stated therein or necessary to make the
statements therein, in light of the circumstances in which they were made, not
false or misleading;

      (q) Neither the Acquiring Fund nor, to the knowledge of the Acquiring
Fund, any "affiliated person" of the Acquiring Fund has been convicted of any
felony or misdemeanor, described in Section 9(a)(1) of the Investment Company
Act, nor, to the knowledge of the Acquiring Fund, has any affiliated person of
the Acquiring Fund been the subject, or presently is the subject, of any
proceeding or investigation with respect to any disqualification that would be a
basis for denial, suspension or revocation of registration as an investment
adviser under Section 203(e) of the Investment Advisers Act or Rule 206(4)-4(b)
thereunder or of a broker-dealer under Section 15 of the Exchange Act, or for
disqualification as an investment adviser, employee, officer or director of an
investment company under Section 9 of the Investment Company Act; and

      (r) The tax representation certificate to be delivered by the Trust, on
behalf of the Acquiring Fund, to Morgan, Lewis & Bockius LLP with respect to
each Reorganization at the applicable Closing of that Reorganization pursuant to
Paragraph 6.3 (the "Acquiring Fund Tax Representation Certificate") will not on
the applicable Closing Date contain any untrue statement of a material fact or
omit to state a material fact necessary to make the statements therein not
misleading.

connection with the transactions provided for herein.

      9.2 Amundi Pioneer will pay 50% of the expenses incurred in connection
with each Reorganization (including, but not limited to, the preparation of the
registration statement on Form N-14). Each Acquired Fund agrees to pay 25% of
the expenses incurred in connection with the Reorganization of such Acquired
Fund (including, but not limited to, the preparation of the registration
statement on Form N-14). The Acquiring Fund agrees to pay 25% of the expenses
incurred in connection with each Reorganization (including, but not limited to,
the preparation of the registration statement on Form N-14). Notwithstanding any
of the foregoing, expenses will in any event be paid by the party directly
incurring such expenses if and to the extent that the payment by another person
of such expenses would result in a failure by any Fund to qualify for treatment
as a "regulated investment company" within the meaning of Section 851 of the
Code or would prevent a Reorganization from qualifying as a "reorganization"
within the meaning of Section 368 of the Code or otherwise result in the
imposition of tax on a Fund or on a Fund's shareholders.

10. ENTIRE AGREEMENT; SURVIVAL OF WARRANTIES

      10.1 The Acquiring Fund and each Acquired Fund agrees that no party has
made any representation, warranty or covenant not set forth herein or referred
to in Paragraphs 4.1 or 4.2 hereof and that this Agreement constitutes the
entire agreement among the parties.

      10.2 The covenants to be performed after the Closing of a Reorganization
by the Acquiring Fund and the applicable Acquired Fund shall survive the
Closing. The representations and warranties and all other covenants contained in
this Agreement or in any document delivered pursuant hereto or in connection
herewith shall not survive the consummation of the transactions contemplated
hereunder.

11. TERMINATION

      11.1 This Agreement may be terminated with respect to the Reorganization
of an Acquired Fund by the mutual agreement of the Acquiring Fund and that
Acquired Fund. In addition, either party to a Reorganization may at its option
terminate this Agreement with respect to such Reorganization at or prior to the
applicable Closing Date:

      (a) by resolution of the Trust's Board of Trustees if circumstances should
develop that, in the good faith opinion of such Board, make proceeding with the
Agreement not in the best interests of the Acquiring Fund's shareholders; or

      (b) by resolution of the Trust's Board of Trustees if circumstances should
develop that, in the good faith opinion of such Board, make proceeding with the
Agreement not in the best interests of such Acquired Fund's shareholders.

      11.2 In the event of any such termination, there shall be no liability for
damages on the part of the Trust, the Acquiring Fund or such Acquired Fund, or
the trustees or officers of the Trust, but, subject to Paragraph 9.2, each party
shall bear the expenses incurred by it incidental to the preparation and
carrying out of this Agreement.

      11.3 The termination of this Agreement with respect to an Acquired Fund
shall not affect the continued effectiveness of this Agreement with respect to
the other Acquired Fund, nor shall it affect the rights and obligations of any
party in respect of any breach of this Agreement occurring prior to such
termination.

12. AMENDMENTS

      This Agreement may be amended, modified or supplemented in such manner as
may be mutually agreed upon in writing by the authorized officers of the Trust;
provided that nothing contained in this Section 12 shall be construed to
prohibit the parties from amending this Agreement to change the Closing Date of
a Reorganization.

13. NOTICES

      Any notice, report, statement or demand required or permitted by any
provision of this Agreement shall be in writing and shall be given by prepaid
telegraph, telecopy or certified mail addressed to the Trust at 60 State Street,

interpretation of this Agreement.

      14.2 This Agreement may be executed in any number of counterparts, each of
which shall be deemed an original.

      14.3 This Agreement shall be governed by and construed in accordance with
the internal laws of the State of Delaware, without giving effect to conflict of
laws principles (other than Delaware Code Title 6 [section] 2708); provided
that, in the case of any conflict between those laws and the federal securities
laws, the latter shall govern.

      14.4 This Agreement shall bind and inure to the benefit of the parties
hereto and their respective successors and assigns, but no assignment or
transfer hereof or of any rights or obligations hereunder shall be made by any
party without the prior written consent of the other parties. Nothing herein

and their respective successors and assigns, any rights or remedies under or by
reason of this Agreement.

                                  INTRODUCTION

     This Statement of Additional Information is intended to supplement the
information provided in an Information Statement and Prospectus dated
______________, 2017 (the "Information Statement and Prospectus") relating to
the reorganization of each of Pioneer Solutions -- Conservative Fund and
Pioneer Solutions -- Growth Fund into Pioneer Solutions -- Balanced Fund.

                EXHIBITS AND DOCUMENTS INCORPORATED BY REFERENCE

     The following documents are incorporated herein by reference, unless
otherwise indicated. Shareholders will receive a copy of each document that is
incorporated by reference upon any request to receive a copy of this Statement
of Additional Information.

1. Statement of Additional Information for each of Pioneer Solutions --
Conservative Fund, Pioneer Solutions -- Balanced Fund and Pioneer Solutions --
Growth Fund, dated December 1, 2016, as supplemented (File Nos. 333-114788 and
811-21569), as filed with the Securities and Exchange Commission on November
22, 2016 (Accession No. 0001288255-16-000040) is incorporated herein by
reference.

2. The Annual Report of each of Pioneer Solutions -- Conservative Fund, Pioneer
Solutions -- Balanced Fund and Pioneer Solutions -- Growth Fund, for the fiscal
year ended July 31, 2017 (File No. 811-21569), as filed with the Securities and
Exchange Commission on September 29, 2017 (Accession No. 0001288255-17-000008)
is incorporated herein by reference.

                          ADDITIONAL INFORMATION ABOUT
                               EACH PIONEER FUND

     Additional information about each Pioneer Fund can be found in the most
recent Statement of Additional Information of each Pioneer Fund, which is
incorporated by reference into this registration statement.

                    PRO FORMA COMBINED FINANCIAL STATEMENTS

     Shown below in connection with the reorganization of each of Pioneer
Solutions -- Conservative Fund and Pioneer Solutions -- Growth Fund (each, an
"Acquired Fund") into Pioneer Solutions -- Balanced Fund (the "Acquiring Fund")
are the financial statements for each of the Pioneer Funds and the pro forma
financial statements for the combined fund, assuming each Reorganization has
been consummated on July 31, 2017.

     The first table presents the Schedule of Investments for each Pioneer Fund
and pro forma figures for the combined fund. The second table presents the
Statements of Assets and Liabilities for each Pioneer Fund and estimated pro
forma figures for the combined fund. The third table presents the Statements of
Operations for each Pioneer Fund and estimated pro forma figures for the
combined fund.

     Because both Acquired Funds may reorganize with the Acquiring Fund, the
tables show the three possibilities that may result: (1) both Acquired Funds
reorganize with the Acquiring Fund; (2) only Pioneer Solutions -- Conservative
Fund reorganizes with the Acquiring Fund; or (3) only Pioneer Solutions --
Growth Fund reorganizes with the Acquiring fund.

     These tables are followed by the Notes to the Pro Forma Financial
Statements.

     These Pro Forma Financial Statements and related Notes should be read in
conjunction with the financial statements of the Acquiring Fund and each
Acquired Fund included in their annual report to shareowners dated July 31,
2017.

NOTES TO PRO FORMA COMBINED FINANCIAL STATEMENTS

Pioneer Solutions -- Balanced Fund
July 31, 2017

1. Description of The Fund

Pioneer Asset Allocation Trust (the "Trust") is organized as a Delaware
statutory trust and is registered with the Securities and Exchange Commission
under the Investment Company Act of 1940 (the "1940 Act") as an open-end
management investment company. The Trust consists of three separate funds
(each, a "Fund," and collectively, the "Funds"), each issuing four classes of
shares as follows:

Pioneer Solutions -- Conservative Fund ("Conservative Fund")

Pioneer Solutions -- Growth Fund ("Growth Fund")

Pioneer Solutions -- Balanced Fund ("Balanced Fund").

The investment objective of each of the Conservative Fund, the Growth Fund and
the Balanced Fund is to seek long-term capital growth and current income.

Each Fund is a "fund of funds." Each Fund seeks to achieve its investment
objective by investing primarily in other funds ("underlying funds"). Each Fund
may also invest directly in securities and use derivatives. Each Fund invests
mainly in funds managed by Amundi Pioneer Asset Management, Inc., formerly
Pioneer Investment Management, Inc. Each Fund may also invest in unaffiliated
mutual funds or exchange-traded funds ("ETFs"). The Funds indirectly pay a
portion of the expenses incurred by underlying funds. Consequently, an
investment in the Funds entails more direct and indirect expenses than direct
investment in the applicable underlying funds.

Each Fund offers four classes of shares designated as Class A, Class C, Class R
and Class Y shares. Each class of shares represents an interest in the same
portfolio of investments of each Fund and has identical rights (based on
relative net asset values) to assets and liquidation proceeds. Share classes
can bear different rates of class-specific fees and expenses such as transfer
agent and distribution fees. Differences in class specific fees and expenses
will result in differences in net investment income and, therefore, the payment
of different dividends from net investment income earned by each class. The
Amended and Restated Declaration of Trust of each Fund gives the Board of
Trustees the flexibility to specify either per-share voting or dollar-weighted
voting when submitting matters for shareowner approval. Under per-share voting,
each share of a class of a Fund is entitled to one vote. Under dollar-weighted
voting, a shareowner's voting power is determined not by the number of shares
owned, but by the dollar value of the shares on the record date. Each share
class has exclusive voting rights with respect to matters affecting only that
class, including with respect to the distribution plan for that class. There is
no distribution plan for Class Y shares.

On July 3, 2017, Amundi acquired Pioneer Investments, a group of asset
management companies located throughout the world. Amundi, one of the world's
largest asset managers, is headquartered in Paris, France. As a result of the
transaction, Pioneer Investment Management, Inc., the Funds' investment
adviser, became an indirect wholly owned subsidiary of Amundi and Amundi's
wholly owned subsidiary, Amundi USA, Inc. Prior to July 3, 2017, Pioneer
Investments was owned by Pioneer Global Asset Management S.p.A., a wholly owned
subsidiary of UniCredit S.p.A.

In connection with the transaction, the names of the Funds' investment adviser
and principal underwriter changed. Effective July 3, 2017, the name of Pioneer
Investment Management, Inc. changed to Amundi Pioneer Asset Management, Inc.
(the "Adviser") and the name of Pioneer Funds Distributor, Inc. changed to
Amundi Pioneer Distributor, Inc. (the "Distributor").

In October 2016, the Securities and Exchange Commission ("SEC") released its
Final Rule on Investment Company Reporting Modernization. In addition to
introducing two new regulatory reporting forms (Form N-PORT and Form N-CEN),
the Final Rule amends Regulation S-X, which impacts financial statement
presentation, particularly related to the presentation of derivative
investments. Financial statements filed with the SEC with a period end date on
or after August 1, 2017 are required to be in compliance with the amendments to
Regulation S-X. Although still evaluating the impact of these amendments,
management expects the Fund's adoption to be limited to additional financial
statement disclosures.

The financial statements have been prepared in conformity with U.S. generally
accepted accounting principles ("U.S. GAAP") that require the management of the
Funds to make estimates and assumptions that affect the reported amounts of
assets and liabilities at the date of the financial statements and the reported
amounts of income and expenses during the reporting period. Actual results
could differ from these estimates.

Each Fund is an investment company and follows investment company accounting
and reporting guidance under U.S. GAAP.

2. Basis of Combination

The accompanying pro forma combining financial statements, and related notes,
are presented to show the effect of the proposed Reorganization of Growth Fund,
Conservative Fund and Balanced Fund (the "Reorganization"), as if such
Reorganization had taken place as of July 31, 2017.

Under the terms of an Agreement and Plan of Reorganization between these three
funds, the combination of Balanced Fund and Growth Fund and Conservative Fund
will be treated as a tax-free business combination and accordingly will be
accounted for by a method of accounting for tax-free reorganizations of
investment companies. The Reorganization will be accomplished by an acquisition
of the net assets of the Growth Fund and Conservative Fund in exchange for
shares of Balanced Fund at Balanced Fund's net asset values. The accompanying
schedules of investments, statements of assets and liabilities and the related
statements of operations of Balanced Fund and Growth Fund and Conservative Fund
have been combined as of and for the twelve months ended July 31, 2017.
Following the Reorganization, Balanced Fund will be the accounting survivor.
The Adviser has agreed to pay 50% of the expenses associated with the
Reorganization, Balanced Fund will pay 25% of the costs of the
reorganization, and Growth Fund and Conservative Fund will equally bear the
remaining costs of the Reorganization. These costs are reflected in the pro
forma financial statements.

These pro forma financial statements and related notes should be read in
conjunction with the financial statements of Balanced Fund, the Growth Fund and
Conservative Fund included in their respective annual reports to shareowners
dated July 31, 2017. The schedule of investments and the statement of assets
and liabilities have been shown to reflect the liquidation of certain
securities and derivative investments held by Balanced Fund the Growth Fund and
Conservative Fund that no longer comply with Balanced Fund's new prospectus
mandate. Proceeds from the sale of investment securities have been reallocated
into existing ETF and affiliated investments held by Balanced Fund. Proceeds
from the sale of derivative investments have been redeemed for cash. The
statement of operations reflect the realized gain/loss from the sale of
investments and derivative holdings and other adjustments made to expenses for
affiliate contractual rates and duplicate services that would not have been
incurred if the Reorganization took place on August 1, 2016.

3. Security Valuation

The net asset value of the Funds are computed once daily, on each day the New
York Stock Exchange ("NYSE") is open, as of the close of regular trading on the
NYSE.

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

Fixed-income securities are valued by using prices supplied by independent
pricing services, which consider such factors as market prices, market events,
quotations from one or more brokers, Treasury spreads, yields, maturities and
ratings, 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. When independent third party pricing
services are unable to supply prices, or when prices or market quotations are
considered to be unreliable, the value of that security may be determined using
quotations from one or more broker-dealers.

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

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

Options contracts are generally valued at the mean between the last bid and ask
prices on the principal exchange where they are traded. Over-the-counter
("OTC") options and options on swaps ("swaptions") are valued using prices
supplied by independent pricing services, which consider such factors as market
prices, market events, quotations from one or more brokers, Treasury spreads,
yields, maturities and ratings, or may use a pricing matrix or other fair value
methods or techniques to provide an estimated value of the security or
instrument.

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

Securities for which independent pricing services or broker-dealers are unable
to supply prices or for which market prices and/or quotations are not readily
available or are considered to be unreliable are valued by a fair valuation
team comprised of certain personnel of the Adviser, pursuant to procedures
adopted by the Funds' Board of Trustees. The Adviser's fair valuation team uses
fair value methods approved by the Valuation Committee of the Board of
Trustees. The Adviser's fair valuation team is responsible for monitoring
developments that may impact fair valued securities and for discussing and
assessing fair values on an ongoing basis, and at least quarterly, with the
Valuation Committee of the Board of Trustees.

Inputs used when applying fair value methods to value a security may include
credit ratings, the financial condition of the company, current market
conditions and comparable securities. the Funds may use fair value methods if
it is determined that a significant event has occurred after the close of the
exchange or market on which the security trades and prior to the determination
of each Fund's net asset value. Examples of a significant event might include
political or economic news, corporate restructurings, natural disasters,
terrorist activity or trading halts. Thus, the valuation of each Fund's
securities may differ significantly from exchange prices and such differences
could be material.

At July 31, 2017, the Funds held no securities valued using fair value methods
(other than to securities valued using prices supplied by independent pricing
services, broker-dealers or using a third party insurance industry pricing
model).

4. Investment Income and Transactions

Dividend income and realized capital gain distributions from investment company
shares held are recorded on the ex-dividend date. Interest income, including
interest on income bearing cash accounts, is recorded on the accrual basis.
Dividend and interest income are reported net of unrecoverable foreign taxes
withheld at the applicable country rates.

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

5. Capital Shares

The pro forma net asset value per share assumes the issuance of shares of the
Balanced Fund that would have been issued at July 31, 2017, in connection with
the proposed Reorganization. The number of shares assumed to be issued is equal
to the net assets of the Growth Fund and Conservative Fund , as of July 31,
2017, divided by the net asset value of Balanced Fund's shares as of July 31,
2017. The pro forma number of shares outstanding, by class, for the combined
Fund consists of the following at July 31, 2017:



                                                       Additional               Total

6. Management Agreement

The Adviser manages the Funds' portfolios. Management fees for the Fund are
calculated daily at an annual rate equal to 0.13% of the Fund's average daily
net assets up to $2.5 billion; 0.11% of the Fund's average daily net assets
over $2.5 billion up to $4 billion; 0.10% of the Fund's average daily net
assets over $4 billion up to $5.5 billion; and 0.08% of the Fund's average
daily net assets over $5.5 billion.

For the year ended July 31, 2017, the effective management fee for the Fund was
equivalent to 0.13% of the Fund's average daily net assets. Fees waived and
expenses reimbursed during the year ended July 31, 2017 are reflected in the
Statements of Operations.

The Adviser has contractually agreed to limit ordinary operating expenses to the
extent required to reduce fund expenses, other than underlying fund fees and
expenses, to 0.70%, 1.45%, and 0.90% of the average daily net assets
attributable to Class A, Class C and Class R shares, respectively. Fees waived
and expenses reimbursed during the twelve months ended July 31, 2017, are
reflected on the Statement of Operations. The Adviser has agreed to further
limit the ordinary operating expenses of Class R shares of the combined fund
following the completion of the Reorganization to 0.78% of the average daily net
assets attributable to Class R shares. These expense limitations are in effect
through December 1, 2019. There can be no assurance that the Adviser will extend
the expense limitation agreement for a class of shares beyond the date referred
to above.

7. Federal Income Taxes

Each fund has elected to be taxed as a "regulated investment company" under the
Internal Revenue Code. After the acquisition, it will continue to be the Fund's
policy to comply with the requirements of the Internal Revenue Code applicable
to regulated investment companies and to distribute all of its taxable income
and net realized capital gains, if any, to its shareowners. Therefore, no
federal income tax provision is required.

The identified cost of investments for these funds is substantially the same
for both financial and federal income tax purposes. The cost of investments
will remain unchanged for the combined Fund.

NOTES TO PRO FORMA COMBINED FINANCIAL STATEMENTS

Pioneer Solutions -- Balanced Fund
July 31, 2017

1. Description of the Fund

Pioneer Asset Allocation Trust (the "Trust") is organized as a Delaware
statutory trust and is registered with the Securities and Exchange Commission
under the Investment Company Act of 1940 (the "1940 Act") as an open-end
management investment company. The Trust consists of three separate funds
(each, a "Fund," and collectively, the "Funds"), each issuing four classes of
shares as follows:

Pioneer Solutions -- Conservative Fund ("Conservative Fund")

Pioneer Solutions -- Growth Fund ("Growth Fund")

Pioneer Solutions -- Balanced Fund ("Balanced Fund").

The investment objective of each of the Conservative Fund, the Growth Fund and
the Balanced Fund is to seek long-term capital growth and current income.

Each Fund is a "fund of funds." Each Fund seeks to achieve its investment
objective by investing primarily in other funds ("underlying funds"). Each Fund
may also invest directly in securities and use derivatives. Each Fund invests
mainly in funds managed by Amundi Pioneer Asset Management, Inc., formerly
Pioneer Investment Management, Inc. Each Fund may also invest in unaffiliated
mutual funds or exchange-traded funds ("ETFs"). The Funds indirectly pay a
portion of the expenses incurred by underlying funds. Consequently, an
investment in the Funds entails more direct and indirect expenses than direct
investment in the applicable underlying funds.

Each Fund offers four classes of shares designated as Class A, Class C, Class R
and Class Y shares. Each class of shares represents an interest in the same
portfolio of investments of each Fund and has identical rights (based on
relative net asset values) to assets and liquidation proceeds. Share classes
can bear different rates of class-specific fees and expenses such as transfer
agent and distribution fees. Differences in class specific fees and expenses
will result in differences in net investment income and, therefore, the payment
of different dividends from net investment income earned by each class. The
Amended and Restated Declaration of Trust of each Fund gives the Board of
Trustees the flexibility to specify either per-share voting or dollar-weighted
voting when submitting matters for shareowner approval. Under per-share voting,
each share of a class of a Fund is entitled to one vote. Under dollar-weighted
voting, a shareowner's voting power is determined not by the number of shares
owned, but by the dollar value of the shares on the record date. Each share
class has exclusive voting rights with respect to matters affecting only that
class, including with respect to the distribution plan for that class. There is
no distribution plan for Class Y shares.

On July 3, 2017, Amundi acquired Pioneer Investments, a group of asset
management companies located throughout the world. Amundi, one of the world's
largest asset managers, is headquartered in Paris, France. As a result of the
transaction, Pioneer Investment Management, Inc., the Funds' investment
adviser, became an indirect wholly owned subsidiary of Amundi and Amundi's
wholly owned subsidiary, Amundi USA, Inc. Prior to July 3, 2017, Pioneer
Investments was owned by Pioneer Global Asset Management S.p.A., a wholly owned
subsidiary of UniCredit S.p.A.

In connection with the transaction, the names of the Funds' investment adviser
and principal underwriter changed. Effective July 3, 2017, the name of Pioneer
Investment Management, Inc. changed to Amundi Pioneer Asset Management, Inc.
("the Adviser") and the name of Pioneer Funds Distributor, Inc. changed to
Amundi Pioneer Distributor, Inc. (the "Distributor").

In October 2016, the Securities and Exchange Commission ("SEC") released its
Final Rule on Investment Company Reporting Modernization. In addition to
introducing two new regulatory reporting forms (Form N-PORT and Form N-CEN),
the Final Rule amends Regulation S-X, which impacts financial statement
presentation, particularly related to the presentation of derivative
investments. Financial statements filed with the SEC with a period end date on
or after August 1, 2017 are required to be in compliance with the amendments to
Regulation S-X. Although still evaluating the impact of these amendments,
management expects the Fund's adoption to be limited to additional financial
statement disclosures.

The financial statements have been prepared in conformity with U.S. generally
accepted accounting principles ("U.S. GAAP") that require the management of the
Funds to make estimates and assumptions that affect the reported amounts of
assets and liabilities at the date of the financial statements and the reported
amounts of income and expenses during the reporting period. Actual results
could differ from these estimates.

Each Fund is an investment company and follows investment company accounting
and reporting guidance under U.S. GAAP.

2. Basis of Combination

The accompanying pro forma combining financial statements, and related notes,
are presented to show the effect of the proposed Reorganization of Conservative
Fund with and into the Balanced Fund (the "Reorganization"), as if such
Reorganization had taken place as of July 31, 2017.

Under the terms of an Agreement and Plan of Reorganization between these two
funds, the combination of the Balanced Fund and Conservative Fund will be
treated as a tax-free business combination and accordingly will be accounted
for by a method of accounting for tax-free reorganizations of investment
companies. The Reorganization will be accomplished by an acquisition of the net
assets of the Conservative Fund in exchange for shares of the Balanced Fund at
the Balanced Fund's net asset values. The accompanying schedules of
investments, statements of assets and liabilities and the related statements of
operations of the Balanced Fund and Conservative Fund have been combined as of
and for the twelve months ended July 31, 2017. Following the Reorganization,
the Fund will be the accounting survivor. The Adviser has agreed to pay 50% of
the expenses associated with the Reorganization, and the Balanced Fund and
Conservative Fund will equally bear the remaining costs of the Reorganization.
These costs are reflected in the pro forma financial statements.

These pro forma financial statements and related notes should be read in
conjunction with the financial statements of the Balanced Fund and Conservative
Fund included in their respective annual reports to shareowners dated July 31,
2017. The schedule of investments and the statement of assets and liabilities
have been shown to reflect the liquidation of certain securities and derivative
investments held by the Balanced Fund and Conservative Fund that no longer
comply with the Balanced Fund's new prospectus mandate. Proceeds from the sale
of investment securities have been reallocated into existing ETF and affiliated
investments held by the Balanced Fund. Proceeds from the sale of derivative
investments have been redeemed for cash. The statement of operations reflect
the realized gain/loss from the sale of investments and derivative holdings and
other adjustments made to expenses for affiliate contractual rates and
duplicate services that would not have been incurred if the Reorganization took
place on August 1, 2016.

3. Security Valuation

The net asset value of the Funds are computed once daily, on each day the New
York Stock Exchange ("NYSE") is open, as of the close of regular trading on the
NYSE.

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

Fixed-income securities are valued by using prices supplied by independent
pricing services, which consider such factors as market prices, market events,
quotations from one or more brokers, Treasury spreads, yields, maturities and
ratings, 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. When independent third party pricing
services are unable to supply prices, or when prices or market quotations are
considered to be unreliable, the value of that security may be determined using
quotations from one or more broker-dealers.

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

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

Options contracts are generally valued at the mean between the last bid and ask
prices on the principal exchange where they are traded. Over-the-counter
("OTC") options and options on swaps ("swaptions") are valued using prices
supplied by independent pricing services, which consider such factors as market
prices, market events, quotations from one or more brokers, Treasury spreads,
yields, maturities and ratings, or may use a pricing matrix or other fair value
methods or techniques to provide an estimated value of the security or
instrument.

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

                                    SAI--20


Securities for which independent pricing services or broker-dealers are unable
to supply prices or for which market prices and/or quotations are not readily
available or are considered to be unreliable are valued by a fair valuation
team comprised of certain personnel of the Adviser, pursuant to procedures
adopted by the Funds' Board of Trustees. The Adviser's fair valuation team uses
fair value methods approved by the Valuation Committee of the Board of
Trustees. The Adviser's fair valuation team is responsible for monitoring
developments that may impact fair valued securities and for discussing and
assessing fair values on an ongoing basis, and at least quarterly, with the
Valuation Committee of the Board of Trustees.

Inputs used when applying fair value methods to value a security may include
credit ratings, the financial condition of the company, current market
conditions and comparable securities. The Funds may use fair value methods if
it is determined that a significant event has occurred after the close of the
exchange or market on which the security trades and prior to the determination
of each Fund's net asset value. Examples of a significant event might include
political or economic news, corporate restructurings, natural disasters,
terrorist activity or trading halts. Thus, the valuation of each Fund's
securities may differ significantly from exchange prices and such differences
could be material.

At July 31, 2017, the Funds held no securities valued using fair value methods
(other than to securities valued using prices supplied by independent pricing
services, broker-dealers or using a third party insurance industry pricing
model).

4. Investment Income and Transactions

Dividend income and realized capital gain distributions from investment company
shares held are recorded on the ex-dividend date. Interest income, including
interest on income bearing cash accounts, is recorded on the accrual basis.
Dividend and interest income are reported net of unrecoverable foreign taxes
withheld at the applicable country rates.

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

5. Capital Shares

The pro forma net asset value per share assumes the issuance of shares of the
Balanced Fund that would have been issued at July 31, 2017, in connection with
the proposed Reorganization. The number of shares assumed to be issued is equal
to the net assets of the Conservative Fund, as of July 31, 2017, divided by the
net asset value of the Balanced Fund's shares as of July 31, 2017. The pro
forma number of shares outstanding, by class, for the combined Fund consists of
the following at July 31, 2017:



                                              Additional                 Total

Class R                        2,590                 759                 3,349
Class Y                       57,903              21,122                79,025


6. Management Agreement

The Adviser manages the Funds' portfolios. Management fees for the Fund are
calculated daily at an annual rate equal to 0.13% of the Fund's average daily
net assets up to $2.5 billion; 0.11% of the Fund's average daily net assets
over $2.5 billion up to $4 billion; 0.10% of the Fund's average daily net
assets over $4 billion up to $5.5 billion; and 0.08% of the Fund's average
daily net assets over $5.5 billion.

For the year ended July 31, 2017, the effective management fee for the Balanced
Fund was equivalent to 0.13% of the Fund's average daily net assets. Fees
waived and expenses reimbursed during the year ended July 31, 2017 are
reflected in the Statements of Operations.

The Adviser has contractually agreed to limit ordinary operating expenses to the
extent required to reduce fund expenses, other than underlying fund fees and
expenses, to 0.70%, 1.45%, and 0.90% of the average daily net assets
attributable to Class A, Class C and Class R shares, respectively. Fees waived
and expenses reimbursed during the twelve months ended July 31, 2017, are
reflected on the Statement of Operations. The Adviser has agreed to further
limit the ordinary operating expenses of Class R shares of the combined fund
following the completion of the Reorganization to 0.78% of the average daily net
assets attributable to Class R shares. These expense limitations are in effect
through December 1, 2019. There can be no assurance that the Adviser will extend
the expense limitation agreement for a class of shares beyond the date referred
to above.



                                    SAI--21


7. Federal Income Taxes

Each fund has elected to be taxed as a "regulated investment company" under the
Internal Revenue Code. After the acquisition, it will continue to be the Fund's
policy to comply with the requirements of the Internal Revenue Code applicable
to regulated investment companies and to distribute all of its taxable income
and net realized capital gains, if any, to its shareowners. Therefore, no
federal income tax provision is required.

The identified cost of investments for these funds is substantially the same
for both financial and federal income tax purposes. The cost of investments
will remain unchanged for the combined Fund.

NOTES TO PRO FORMA COMBINED FINANCIAL STATEMENTS

Pioneer Solutions -- Balanced Fund
July 31, 2017

1. Description of the Fund

Pioneer Asset Allocation Trust (the "Trust") is organized as a Delaware
statutory trust and is registered with the Securities and Exchange Commission
under the Investment Company Act of 1940 (the "1940 Act") as an open-end
management investment company. The Trust consists of three separate funds
(each, a "Fund," and collectively, the "Funds"), each issuing four classes of
shares as follows:

Pioneer Solutions -- Conservative Fund ("Conservative Fund")

Pioneer Solutions -- Growth Fund ("Growth Fund")

Pioneer Solutions -- Balanced Fund ("Balanced Fund").

The investment objective of each of the Conservative Fund, the Growth Fund and
the Balanced Fund is to seek long-term capital growth and current income.

Each Fund is a "fund of funds." Each Fund seeks to achieve its investment
objective by investing primarily in other funds ("underlying funds"). Each Fund
may also invest directly in securities and use derivatives. Each Fund invests
mainly in funds managed by Amundi Pioneer Asset Management, Inc., formerly
Pioneer Investment Management, Inc. Each Fund may also invest in unaffiliated
mutual funds or exchange-traded funds ("ETFs"). The Funds indirectly pay a
portion of the expenses incurred by underlying funds. Consequently, an
investment in the Funds entails more direct and indirect expenses than direct
investment in the applicable underlying funds.

Each Fund offers four classes of shares designated as Class A, Class C, Class R
and Class Y shares. Each class of shares represents an interest in the same
portfolio of investments of each Fund and has identical rights (based on
relative net asset values) to assets and liquidation proceeds. Share classes
can bear different rates of class-specific fees and expenses such as transfer
agent and distribution fees. Differences in class specific fees and expenses
will result in differences in net investment income and, therefore, the payment
of different dividends from net investment income earned by each class. The
Amended and Restated Declaration of Trust of each Fund gives the Board of
Trustees the flexibility to specify either per-share voting or dollar-weighted
voting when submitting matters for shareowner approval. Under per-share voting,
each share of a class of a Fund is entitled to one vote. Under dollar-weighted
voting, a shareowner's voting power is determined not by the number of shares
owned, but by the dollar value of the shares on the record date. Each share
class has exclusive voting rights with respect to matters affecting only that
class, including with respect to the distribution plan for that class. There is
no distribution plan for Class Y shares.

On July 3, 2017, Amundi acquired Pioneer Investments, a group of asset
management companies located throughout the world. Amundi, one of the world's
largest asset managers, is headquartered in Paris, France. As a result of the
transaction, Pioneer Investment Management, Inc., the Funds' investment
adviser, became an indirect wholly owned subsidiary of Amundi and Amundi's
wholly owned subsidiary, Amundi USA, Inc. Prior to July 3, 2017, Pioneer
Investments was owned by Pioneer Global Asset Management S.p.A., a wholly owned
subsidiary of UniCredit S.p.A.

In connection with the transaction, the names of the Funds' investment adviser
and principal underwriter changed. Effective July 3, 2017, the name of Pioneer
Investment Management, Inc. changed to Amundi Pioneer Asset Management, Inc.
(the "Adviser") and the name of Pioneer Funds Distributor, Inc. changed to
Amundi Pioneer Distributor, Inc. (the "Distributor").

In October 2016, the Securities and Exchange Commission ("SEC") released its
Final Rule on Investment Company Reporting Modernization. In addition to
introducing two new regulatory reporting forms (Form N-PORT and Form N-CEN),
the Final Rule amends Regulation S-X, which impacts financial statement
presentation, particularly related to the presentation of derivative
investments. Financial statements filed with the SEC with a period end date on
or after August 1, 2017 are required to be in compliance with the amendments to
Regulation S-X. Although still evaluating the impact of these amendments,
management expects the Fund's adoption to be limited to additional financial
statement disclosures.

The financial statements have been prepared in conformity with U.S. generally
accepted accounting principles ("U.S. GAAP") that require the management of the
Funds to make estimates and assumptions that affect the reported amounts of
assets and liabilities at the date of the financial statements and the reported
amounts of income and expenses during the reporting period. Actual results
could differ from these estimates.

                                    SAI--29


Each Fund is an investment company and follows investment company accounting
and reporting guidance under U.S. GAAP.

2. Basis of Combination

The accompanying pro forma combining financial statements, and related notes,
are presented to show the effect of the proposed Reorganization of Growth Fund
with and into the Balanced Fund (the "Reorganization"), as if such
Reorganization had taken place as of July 31, 2017.

Under the terms of an Agreement and Plan of Reorganization between these two
funds, the combination of the Balanced Fund and Growth Fund will be treated as
a tax-free business combination and accordingly will be accounted for by a
method of accounting for tax-free reorganizations of investment companies. The
Reorganization will be accomplished by an acquisition of the net assets of the
Growth Fund in exchange for shares of the Balanced Fund at the Balanced Fund's
net asset values. The accompanying schedules of investments, statements of
assets and liabilities and the related statements of operations of the Balanced
Fund and Growth Fund have been combined as of and for the twelve months ended
July 31, 2017. Following the Reorganization, the Fund will be the accounting
survivor. The Adviser has agreed to pay 50% of the expenses associated with
the Reorganization, and the Balanced Fund and Growth Fund will equally bear the
remaining costs of the Reorganization. These costs are reflected in the pro
forma financial statements.

These pro forma financial statements and related notes should be read in
conjunction with the financial statements of the Balanced Fund and Growth Fund
included in their respective annual reports to shareowners dated July 31, 2017.
The schedule of investments and the statement of assets and liabilities have
been shown to reflect the liquidation of certain securities and derivative
investments held by the Balanced Fund and Growth Fund that no longer comply
with the Balanced Fund's new prospectus mandate. Proceeds from the sale of
investment securities have been reallocated into existing ETF and affiliated
investments held by the Balanced Fund. Proceeds from the sale of derivative
investments have been redeemed for cash. The statement of operations reflect
the realized gain/loss from the sale of investments and derivative holdings and
other adjustments made to expenses for affiliate contractual rates and
duplicate services that would not have been incurred if the Reorganization took
place on August 1, 2016.

3. Security Valuation

The net asset value of the Funds are computed once daily, on each day the New
York Stock Exchange ("NYSE") is open, as of the close of regular trading on the
NYSE.

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

Fixed-income securities are valued by using prices supplied by independent
pricing services, which consider such factors as market prices, market events,
quotations from one or more brokers, Treasury spreads, yields, maturities and
ratings, 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. When independent third party pricing
services are unable to supply prices, or when prices or market quotations are
considered to be unreliable, the value of that security may be determined using
quotations from one or more broker-dealers.

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

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

Options contracts are generally valued at the mean between the last bid and ask
prices on the principal exchange where they are traded. Over-the-counter
("OTC") options and options on swaps ("swaptions") are valued using prices
supplied by independent pricing services, which consider such factors as market
prices, market events, quotations from one or more brokers, Treasury spreads,
yields, maturities and ratings, or may use a pricing matrix or other fair value
methods or techniques to provide an estimated value of the security or
instrument.

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

                                    SAI--30


Securities for which independent pricing services or broker-dealers are unable
to supply prices or for which market prices and/or quotations are not readily
available or are considered to be unreliable are valued by a fair valuation
team comprised of certain personnel of the Adviser, pursuant to procedures
adopted by the Funds' Board of Trustees. The Adviser's fair valuation team uses
fair value methods approved by the Valuation Committee of the Board of
Trustees. The Adviser's fair valuation team is responsible for monitoring
developments that may impact fair valued securities and for discussing and
assessing fair values on an ongoing basis, and at least quarterly, with the
Valuation Committee of the Board of Trustees.

Inputs used when applying fair value methods to value a security may include
credit ratings, the financial condition of the company, current market
conditions and comparable securities. The Funds may use fair value methods if
it is determined that a significant event has occurred after the close of the
exchange or market on which the security trades and prior to the determination
of each Fund's net asset value. Examples of a significant event might include
political or economic news, corporate restructurings, natural disasters,
terrorist activity or trading halts. Thus, the valuation of each Fund's
securities may differ significantly from exchange prices and such differences
could be material.

At July 31, 2017, the Funds held no securities valued using fair value methods
(other than to securities valued using prices supplied by independent pricing
services, broker-dealers or using a third party insurance industry pricing
model).

4. Investment Income and Transactions

Dividend income and realized capital gain distributions from investment company
shares held are recorded on the ex-dividend date. Interest income, including
interest on income bearing cash accounts, is recorded on the accrual basis.
Dividend and interest income are reported net of unrecoverable foreign taxes
withheld at the applicable country rates.

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

5. Capital Shares

The pro forma net asset value per share assumes the issuance of shares of the
Balanced Fund that would have been issued at July 31, 2017, in connection with
the proposed Reorganization. The number of shares assumed to be issued is equal
to the net assets of the Growth Fund, as of July 31, 2017, divided by the net
asset value of the Balanced Fund's shares as of July 31, 2017. The pro forma
number of shares outstanding, by class, for the combined Fund consists of the
following at July 31, 2017:



                                                   Additional                  Total
                            Shares of          Shares Assumed            Outstanding
                        Balanced Fund               Issued In                 Shares
Class of Shares       Pre-Combination          Reorganization       Post-Combination
------------------------------------------------------------------------------------
                                                                 
Class A                     9,629,583              20,009,216             29,638,799
Class C                     4,510,554               6,222,883             10,733,437
Class R                         2,590                   3,088                  5,687
Class Y                        57,903                  67,222                125,125


6. Management Agreement

The Adviser manages the Funds' portfolios. Management fees for the Fund are
calculated daily at an annual rate equal to 0.13% of the Fund's average daily
net assets up to $2.5 billion; 0.11% of the Fund's average daily net assets
over $2.5 billion up to $4 billion; 0.10% of the Fund's average daily net
assets over $4 billion up to $5.5 billion; and 0.08% of the Fund's average
daily net assets over $5.5 billion.

For the year ended July 31, 2017, the effective management fee for the Balanced
Fund was equivalent to 0.13% of the Fund's average daily net assets. Fees
waived and expenses reimbursed during the year ended July 31, 2017 are
reflected in the Statements of Operations.

The Adviser has contractually agreed to limit ordinary operating expenses to the
extent required to reduce fund expenses, other than underlying fund fees and
expenses, to 0.70%, 1.45%, and 0.90%of the average daily net assets attributable
to Class A, Class C and Class R shares, respectively. Fees waived and expenses
reimbursed during the twelve months ended July 31, 2017, are reflected on the
Statement of Operations. The Adviser has agreed to further limit the ordinary
operating expenses of Class R shares of the combined fund following the
completion of the Reorganization to 0.78% of the average daily net assets
attributable to Class R shares. These expense limitations are in effect through
December 1, 2019. There can be no assurance that the Adviser will extend the
expense limitation agreement for a class of shares beyond the date referred to
above.


                                    SAI--31


7. Federal Income Taxes

Each fund has elected to be taxed as a "regulated investment company" under the
Internal Revenue Code. After the acquisition, it will continue to be the Fund's
policy to comply with the requirements of the Internal Revenue Code applicable
to regulated investment companies and to distribute all of its taxable income
and net realized capital gains, if any, to its shareowners. Therefore, no
federal income tax provision is required.

The identified cost of investments for these funds is substantially the same
for both financial and federal income tax purposes. The cost of investments
will remain unchanged for the combined Fund.

(*)   Attached as Exhibit A to the combined Information Statement/Prospectus

(**)  Filed herewith.


ITEM 17. UNDERTAKINGS.

(1) The undersigned Registrant agrees that prior to any public reoffering of
the securities registered through the use of a prospectus, which is part of
this registration statement, by any person or party which is deemed to be an
underwriter within the meaning of Rule 145(c) of the Securities Act of 1933,
the reoffering prospectus will contain the information called for by the
applicable registration form for the reofferings by persons who may be deemed
underwriters, in addition to the information called for by the other items of
the applicable form.

(2) The undersigned Registrant agrees that every prospectus that is filed under
paragraph (1) above will be filed as part of an amendment to the registration
statement and will not be used until the amendment is



effective, and that, in determining any liability under the Securities Act of
1933, each post-effective amendment shall be deemed to be a new registration
statement for the securities offered therein, and the offering of the
securities at that time shall be deemed to be the initial bona fide offering of
them.

(3) The undersigned Registrant agrees that it shall file a final executed
version of the legal and consent opinion as to tax matters as an exhibit to the
subsequent post-effective amendment to its registration statement on Form N-14
filed with the SEC upon the closing of the reorganization contemplated by this
Registration Statement on Form N-14.

(4) Insofar as indemnification for liability arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the Registrant of expenses incurred
or paid by a director, officer or controlling person of the Registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the
matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Act and will be governed by the final
adjudication of such issue.



                                  SIGNATURES

   As required by the Securities Act of 1933, this Registration Statement on
Form N-14 has been signed on behalf of the Registrant, in the City of Boston
and the Commonwealth of Massachusetts, on the 31st day of October, 2017.
