                   NOTICE OF SPECIAL MEETING OF SHAREHOLDERS


                        SCHEDULED FOR DECEMBER 8, 2004

To the Shareholders of the Safeco Funds:

     A joint special meeting of shareholders (the "Meeting") for each of the
Safeco Funds will be held at the offices of Safeco Mutual Funds, King
Auditorium, 4854 154th Place, N.E., Redmond, WA 98052, on December 8, 2004 at
2:00 p.m., local time, to consider the following:

     1.   With respect to each Safeco Fund, a proposal to approve an Agreement
          and Plan of Reorganization. Under the Agreement and Plan of
          Reorganization, your Safeco Fund will transfer all of its assets to an
          investment company (each a "Pioneer Fund") managed by Pioneer
          Investment Management, Inc. ("Pioneer") in exchange for Investor Class
          shares of the Pioneer Fund. The Pioneer Fund also will assume your
          Safeco Fund's liabilities that are included in the calculation of your
          Safeco Fund's net assets at the closing. Generally, each Pioneer Fund
          is an existing mutual fund with a substantially similar investment
          objective and similar investment policies as your Safeco Fund. In the
          case of certain Safeco Funds, the Pioneer Fund is a newly organized
          mutual fund with a substantially similar investment objective and
          similar investment policies as your Safeco Fund. Holders of all share
          classes of your Safeco Fund will receive Investor Class shares of the
          corresponding Pioneer Fund. Investor Class shares of the applicable
          Pioneer Fund will be distributed to shareholders in proportion to the
          relative net asset value of their share holdings on the closing date




          of the reorganization. Following the reorganization, your Safeco Fund
          will then be dissolved. As a result of the reorganization you will
          become shareholders of the Pioneer Fund. Your board of trustees
          recommends that you vote FOR this proposal.

     2.   With respect to each Safeco Fund, a proposal to approve an interim
          investment advisory agreement between your Safeco Fund and Pioneer.
          Pioneer has provided advisory services for your Safeco Funds pursuant
          to this agreement since August 2, 2004, when the advisory agreement
          between your Safeco Fund and Safeco Asset Management Company
          terminated. Approval of the interim investment advisory agreement will
          enable Pioneer to receive advisory fees currently held in escrow. Your
          board of trustees recommends that you vote FOR this proposal.


     3.   Any other business that may properly come before the Meeting.


     Shareholders of record as of the close of business on October 8, 2004, are
entitled to vote at the Meeting and any related follow-up meetings.

     Whether or not you expect to attend the Meeting, please complete and return
the enclosed proxy card. If shareholders do not return their proxies in
sufficient numbers, your Safeco Fund may be required to make additional
solicitations.


                                              By order of the Board of Trustees,


                                              [Name]

                                       2


Background to the Reorganizations


     Safeco Asset Management Company ("SAM"), the Safeco Funds' investment
adviser until August 2, 2004, was a subsidiary of Safeco Corporation, a
multi-line insurance company. On August 2, 2004, Symetra Financial Corporation
("Symetra") acquired certain assets from Safeco Corporation, including all of
the capital stock of SAM. While reviewing the operations of SAM in anticipation
of that transaction, Symetra determined that engaging in the business of
investment adviser to the Safeco Funds was not a core business that it intended
to continue. After investigating and discussing several alternatives for ongoing
investment management of the Safeco Funds with the Trustees, Symetra conducted a
search for a new investment adviser for the Safeco Funds. Ultimately Symetra
decided to recommend to the Boards that Pioneer Investment Management, Inc.
("Pioneer") be hired to manage the Safeco Funds on an interim basis until the
Reorganizations occur and the Safeco Funds be reorganized into similar mutual
funds managed by Pioneer.

     The Board met at a series of meetings in July 2004. At these meetings, your
Trustees received and evaluated materials regarding Pioneer and the Pioneer
Funds, including the performance record and expense structure of each of the
Pioneer Funds, the impact of the proposed Reorganizations on the Safeco Funds'
shareholders, and the quality of the services offered by Pioneer. At these
meetings, the Trustees met with representatives of Pioneer. In addition to these
general factors, the Trustees also considered these and other factors
specifically in the context of each Reorganization. On July 30, 2004, the Board,
including all of the Trustees who are not interested persons of SAM (the
"Independent Trustees"), unanimously voted to approve each of the
Reorganizations. In approving the Reorganizations, the Board determined that the
Reorganizations were in the best interests of the Safeco Funds' shareholders and
the interests of existing Safeco Funds' shareholders will not be diluted as a
result of the Reorganizations.

     Pioneer believes that it can offer favorable long-term investment
performance and enhanced shareholder services to the Safeco Funds' shareholders.
The Reorganizations will, by combining the assets of two mutual funds and, by
being part of a family of funds with greater distribution capabilities, offer
the potential for increased economies of scale. Increased economies of scale
have the potential of benefiting the shareholders of your Safeco Funds and the
Pioneer Funds by spreading fixed costs over a larger asset base and reducing
expenses on a per share basis. There can be no assurance that such economies of
scale will be realized.


Why the Trustees are Recommending the Reorganizations


     The Trustees believe that reorganizing your Safeco Fund into a portfolio
with a substantially similar investment objective and similar investment
policies that is part of the Pioneer family of funds offers you potential
benefits. These potential benefits and considerations include:

     o    SAM, the investment adviser to each of the Safeco Funds until August
          2, 2004, was acquired by Symetra. Symetra informed the Board that it
          was not interested in continuing to provide investment advisory
          services to the Safeco Funds. Therefore, a change in your Safeco
          Fund's investment adviser was necessary;


     o    The track record of Pioneer in managing the Pioneer Funds as compared
          to the historical performance of the Safeco Funds;

     o    The resources of Pioneer, including its infrastructure in shareholder
          services;

     o    The opportunity to be part of a significantly larger family of funds,
          with additional product offerings and enhanced shareholder servicing
          options;


     o    Pioneer's commitment until December 10, 2006, or such later date that
          is the second anniversary of the day on which each Reorganization
          closes (the "Closing Date"), to limit the expenses of the Investor
          Class shares of each Pioneer Fund; and

     o    Shareholders who own shares in their name as of the closing of the
          Reorganizations (i.e., not in the name of a broker or other
          intermediary) and maintain their account may purchase Class A shares
          of the corresponding Pioneer Fund through such account in the future
          or may exchange those shares for Class A shares of another Pioneer
          Fund or purchase Class A share of another Pioneer Fund without paying
          any sales charge. Investor Class shares will not be offered after the
          Reorganizations.

How Each Reorganization will Work

     o    Safeco Fund shareholder-directed exchanges and purchases made by
          check, ACH, or wire will be accepted up until 1 p.m. (Pacific Time) on
          Wednesday, December 8, 2004. Exchange and purchase requests received
          after this deadline will be rejected and returned. Purchase and
          exchange requests made by Safeco Fund shareholders through financial
          institutions or advisers must do so earlier to ensure the trade can be
          processed within this deadline. Financial institutions and advisers
          that trade electronically (NSCC) with the Safeco Funds can place
          exchange and purchase requests up until 1 p.m. (Pacific Time) on
          Tuesday, December 7, 2004. Exchanges and purchases received after this
          deadline will be rejected and returned. The Safeco Funds will not
          process purchases made via



                                       3



          automatic investment method (AIM) after December 8, 2004.
          Dividend/capital gain reinvestment and established systematic
          exchanges will continue through December 10, 2004.

     o    Each Safeco Fund will transfer all of its assets to a corresponding
          Pioneer Fund. Each Pioneer Fund will assume the corresponding Safeco
          Fund's liabilities that are included in the calculation of such Safeco
          Fund's net asset value on the Closing Date.

     o    Each Pioneer Fund will issue Investor Class shares to the
          corresponding Safeco Fund in amounts equal to the aggregate net asset
          value of that Safeco Fund's shares. Shareholders of your Safeco Fund
          will receive Investor Class shares of the corresponding Pioneer Fund.
          These shares will be distributed to shareholders in proportion to the
          relative net asset value of their share holdings on the Closing Date.
          On the Closing Date, shareholders will hold the shares of the Pioneer
          Fund with the same aggregate net asset value as the shares of your
          Safeco Fund that you held immediately prior to the Reorganization.


     o    Each Safeco Fund will be dissolved after the Closing Date.

     o    Shares of the Investor Class of a Pioneer Fund will automatically
          convert to Class A shares of the Pioneer Fund at the end of the
          calendar month that is two years after the Closing Date.


     o    Pioneer acts as investment adviser to each Pioneer Fund. Until
          December 10, 2006, or such later date that is the second anniversary
          of the Closing Date, Pioneer has agreed to limit each Pioneer Fund's
          expenses (excluding extraordinary expenses) for Investor Class shares.
          Pioneer is not required to limit any expenses after December 10, 2006,
          or such later date that is the second anniversary of the Closing Date.


     o    The Reorganizations are intended to result in no income, gain or loss
          being recognized for federal income tax purposes to any of the Pioneer
          Funds, the Safeco Funds or the shareholders of the Safeco Funds.


     o    In recommending each of the Reorganizations, the Trustees of your
          Safeco Fund have determined that the Reorganization is in the best
          interest of your Safeco Fund and will not dilute the interests of
          shareholders of your Safeco Fund. The Trustees have made that
          determination on the basis of the factors listed above and discussed
          in more detail under each proposal. A reorganization might not be in
          the best interest of the shareholders of a mutual fund if the
          surviving fund had higher expenses, less experienced management or the
          adviser did not have adequate resources to manage the affairs of the
          mutual fund.

     o    If the Reorganizations are approved, the Safeco Trust will file with
          the SEC an application for deregistration on Form N-8F under the
          Investment Company Act of 1940, as amended (the "Investment Company
          Act"), and will cease to exist as an investment company when such
          application is approved.

Who is Pioneer

     Pioneer is registered as an investment adviser under the Investment
Advisers Act of 1940, as amended, and acts as investment adviser to mutual funds
and institutional accounts. Pioneer or its predecessors have been managing
mutual funds since 1928 and at June 30, 2004 had, together with its affiliates,
over $35 billion in assets under management. Pioneer is an indirect,
wholly-owned subsidiary of UniCredito Italiano S.p.A., an Italian Bank.

     In addition to the Investor Class shares to be issued in the
Reorganization, each Pioneer Fund also offers Class A shares (subject to an
initial sales load and a Rule 12b-1 Plan), Class B shares (subject to a
contingent deferred sales charge and a Rule 12b-1 Plan), and Class C shares
(subject to a contingent deferred sales charge and a Rule 12b-1 Plan). In
addition, most of the Pioneer Funds also offer Class Y shares (which are an
institutional class of shares and are not subject to a sales charge or a Rule
12b-1 Plan) and Class R shares (which are offered only to certain retirement
plans).

Who Bears the Expenses Associated with the Reorganizations

     Pioneer and Symetra will pay all out of pocket expenses of the Safeco Funds
and the Pioneer Funds associated with the Reorganizations, including, but not
limited to: (1) the expenses associated with the preparation, printing and
mailing of any shareholder communications, including this joint Proxy
Statement/Prospectus, and any filings with the SEC and other governmental
authorities in connection with the Reorganizations; (2) the fees and expenses of
any proxy solicitation firm retained in connection with the Reorganizations; (3)
the legal fees and expenses incurred by the Safeco Funds in connection with the
Reorganizations; and (4) the Trustees' fees and out of pocket expenses incurred
as a result of the Reorganizations.

Will Pioneer and Symetra Benefit from the Reorganizations

     Pioneer will benefit from managing a larger pool of assets. Pioneer is also
acquiring certain assets associated with SAM's mutual funds and institutional
account advisory business. In consideration for the acquisition of these assets
and certain covenants from Symetra



                                       4



and SAM, including their assistance in facilitating the Reorganizations and
their obligation to indemnify Pioneer against certain liabilities, Pioneer has
agreed to pay Symetra up to $30 million. This amount is subject to downward
adjustment if the net assets of the Safeco Funds that approve the
Reorganizations (together with assets in certain other accounts) are less than
$2.6 billion. Under this agreement, Pioneer and Symetra have also agreed, among
other things, that (i) once the Investor Class converts to Class A shares,
Pioneer Funds Distributor, Inc. ("PFD"), the principal underwriter of the
Pioneer Funds, shall make payments to Safeco Securities, Inc. ("Safeco
Securities") pursuant to a Rule 12b-1 plan equal to 0.25% of the average daily
net assets attributable to accounts maintained by former shareholders of the
Safeco Funds; (ii) PFD will make additional continuing payments out of its own
resources to Safeco Securities, following Pioneer's acquisition of assets from
SAM, at an annual rate of 0.05% of the average daily net assets of any Pioneer
Fund held by or for the account of any former shareholders of the Safeco Funds
(including assets invested in any Pioneer Fund as a result of the Reorganization
or otherwise) and, in connection with purchases of shares of the Pioneer Funds
by former shareholders of the Safeco Funds after the acquisition, PFD will pay
out of its own resources to Safeco Securities an amount equal to 0.20% of the
amount of such purchases; and (iii) Symetra and SAM will be subject to certain
non-competition provisions.

Why is an Interim Investment Advisory Agreements being Voted On

     Having determined to recommend the Reorganizations, the Trustees elected to
appoint Pioneer as investment adviser to each Safeco Fund until the closing of
the Reorganizations given that Symetra had indicated that it did not wish to
continue to offer investment advisory services to the Safeco Funds. In
connection with the retention of Pioneer, the sub-advisory agreement with Bank
of Ireland Asset Management (U.S.) Limited with respect to Safeco International
Stock Fund, and the sub-advisory agreement with RCM Capital Management LLC with
respect to Safeco Large-Cap Growth Fund, were terminated.

     Under the Investment Company Act, shareholders must approve any new
investment advisory agreement for a Safeco Fund. However, Rule 15a-4 under the
Investment Company Act permits the Board to appoint an adviser on an interim
basis without prior shareholders' approval of an investment advisory agreement
with the adviser if the new adviser agrees to provide such services on the same
terms as the previous adviser. An adviser may act on such an interim basis for a
period of 150 days. Because Pioneer will be making the payment to Symetra as
discussed above, any fees that Pioneer would be entitled to under the interim
investment advisory agreement will be held in escrow until shareholder approval
of the agreement is obtained. If shareholders of a Safeco Fund do not approve
the interim investment advisory agreement, Pioneer will not receive the fee
under the current investment advisory agreement with SAM but instead would be
paid a fee based upon Pioneer's cost in managing the Fund. If the
Reorganizations and the interim investment advisory agreements are not approved
by December 30, 2004, Pioneer will no longer provide advisory services to the
Safeco Funds, unless an extension of the 150 -day period is permitted by a rule
or independent position of the staff of the SEC. If both the Reorganization and
appointment of Pioneer are approved, the interim investment advisory agreement
will continue in effect until the closing of the Reorganization.

What Happens if a Reorganization is not Approved

     If a Reorganization is not approved by shareholders, the Board will
consider what action to take. Such action could include liquidating the Safeco
Fund or seeking SEC relief to permit Pioneer to serve as investment adviser
beyond the 150-day limitation period.

                                  PROPOSAL 1(a)

                Approval of Agreement and Plan of Reorganization


                                     SUMMARY


     The following is a summary of more complete information appearing later in
this Proxy Statement/Prospectus or incorporated herein. You should read
carefully the entire Proxy Statement/Prospectus, including the form of Agreement
and Plan of Reorganization attached as EXHIBIT A-1 because they contain details
that are not in the summary.

     The Investor Class shares to be issued in the Reorganization will convert
to Class A shares after two years. Class A shares will have higher expenses per
share than Investor Class shares due to the Rule 12b-1 Plan. In addition,
although Pioneer has agreed to limit the expenses attributable to Investor Class
shares, Pioneer is not required to limit the expenses attributable to Class A
shares.

     In the table below, if a row extends across the entire table, the policy
disclosed applies to both your Safeco Fund and the Pioneer Fund.

Comparison of Principal Risks of Investing in the Funds

     Because each Fund has a similar investment objective, primary investment
policies and strategies, the Funds are subject to the same principal risks. You
could lose money on your investment in either Fund or not make as much as if you
invested elsewhere if:

     o    The stock market goes down (this risk may be greater in the short
          term)

     o    The Fund's equity investments do not have the growth potential
          originally expected

     o    Stocks selected for income do not achieve the same return as
          securities selected for capital growth


                                       12


     Each Fund also has risks associated with investing in debt securities. Each
     Fund could underperform other investments if:

     o    Interest rates go up causing the value of the Fund's portfolio to
          decline

     o    The issuer of a debt security owned by the Fund defaults on its
          obligation to pay principal or interest or has its credit rating
          downgraded

     o    During periods of declining interest rates, the issuer of a security
          may exercise its option to repay earlier than scheduled, forcing the
          Fund to reinvest in lower yielding securities. This is known as a call
          prepayment risk

     o    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. This
          is known as an extension risk

     o    Pioneer's judgment about the attractiveness, relative value or
          potential appreciation of a particular sector, security or investment
          strategy proves to be incorrect


     The Investor Class shares to be issued in the Reorganization will convert
to Class A shares after two years. Class A shares will have higher expenses per
share than Investor Class shares due to the Rule 12b-1 Plan. In addition,
although Pioneer has agreed to limit the expenses attributable to Investor Class
shares, Pioneer is not required to limit the expenses attributable to Class A
shares.


     Investments in the Funds are not bank deposits and are not insured or
guaranteed by the Federal Deposit Insurance Corporation or any other government
agency. You could lose money by investing in either Fund.

Past Performance


     Set forth below is performance information for each Fund. The bar charts
show how each Fund's total return (not including any deduction for sales
charges) has varied from year to year for each full calendar year. The tables
show average annual total return (before and after taxes) for each Fund over
time for each class of shares (including deductions for sales charges) compared
with a broad-based securities market index. The bar charts give an indication of
the risks of investing in each Fund, including the fact that you could incur a
loss and experience volatility of returns year to year. Past performance before
and after taxes does not indicate future results.

     Pioneer Balanced Fund's Investor Class shares will not be outstanding prior
to the closing of the Reorganization and consequently have no performance
history. However, the performance record of the Investor Class would be modestly
higher than the performance of Class A shares due to the lower expenses
applicable to the Investor Class.

The Funds' Fees and Expenses


     Shareholders of both Funds 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 Fund. The expenses in the tables
appearing below are based on (i) for your Safeco Fund, the expenses of your
Safeco Fund for the period ended December 31, 2003 and (ii) for Pioneer Balanced
Fund, the expenses of Pioneer Balanced Fund for the period ended December 31,
2003. Future expenses for all share classes may be greater or less.

- ----------

(1)  No sales load will apply to shares received in the Reorganization by
     shareholders of your Safeco Fund who become shareholders of record of
     Pioneer Balanced Fund through the Reorganization. In addition, shareholders
     of your Safeco Fund who own shares in their own name (i.e., not in the name
     of a broker or other intermediary) and maintain such account as of the
     closing of the Reorganization may purchase Class A shares of Pioneer
     Balanced Fund or of any fund in the Pioneer family of funds through such
     account in the future without paying a sales charge.

(2)  As described above, SAM had contractually agreed to reimburse Safeco
     Balanced Fund for certain Fund operating expenses (but not all of the
     operating expenses of the Fund) that exceeded the rate of 0.40% per annum
     of the Fund's average daily net assets. This arrangement included all fund
     operating expenses except management fees, Rule 12b-1 fees, brokerage
     commissions, interest, and extraordinary expenses.


(3)  Pioneer has agreed that through the second anniversary of the closing of
     the Reorganization, Pioneer will limit the expenses (excluding
     extraordinary expenses) of the Investor Class shares of Pioneer Balanced
     Fund to 1.10% of average daily net assets.

(4)  There is a higher charge for international wire redemptions, which may vary
     by country or dollar amount.


(5)  A low balance fee is charged once each year in December for accounts with
     balances under $1,000 in your Safeco Fund.

(6)  Purchases of $1,000,000 or more of Class A shares of your Safeco Fund are
     not subject to a front-end sales charge, but a 1.00% deferred sales charge
     will apply to redemptions made in the first twelve months except with
     respect to participant-directed redemptions from qualified retirement
     plans.

(7)  The contingent deferred sales charge on Class B shares of your Safeco Fund
     reduces to zero after six years from purchase, and the Class B shares
     convert to Class A shares at that time.


(8)  The contingent deferred sales charge on Class C shares applies only to
     redemptions made in the first twelve months after purchase.


(9)  The Investor Class shares to be issued in the Reorganization will convert
     to Class A shares after two years. Class A shares will have higher expenses
     per share than Investor Class shares due to the Rule 12b-1 Plan. In
     addition, although Pioneer has agreed to limit the expenses attributable to
     Investor Class shares, Pioneer is not required to limit the expenses
     attributable to Class A shares. Class A shares do not currently have an
     expense limitation.

     The hypothetical example below helps you compare the cost of investing in
each Fund. It assumes that: (a) you invest $10,000 in each Fund for the time
periods shown, (b) you reinvest all dividends and distributions, (c) your
investment has a 5% return each year, (d) each Fund's gross operating expenses
remain the same, (e) the expense limitations are in effect for five years for
Safeco Balanced Fund and two years for Pioneer Balanced Fund and (f) the
Investor Class shares of Pioneer Balanced Fund convert to Class A shares after
two years. The examples are for comparison purposes only and are not a
representation of either Fund's actual expenses or returns, either past or
future.

Reasons for the Proposed Reorganization

     The Trustees believe that the proposed Reorganization is in the best
interests of Safeco Balanced Fund. The Trustees considered the following
matters, among others, in approving the proposal.


     First, SAM, the investment adviser to the Fund until August 2, 2004, was
acquired by Symetra. Symetra informed the Trustees that it did not intend to
continue to provide investment advisory services to the Safeco Funds.
Consequently, a change in your Safeco Fund's investment adviser was necessary.

     Second, the investment performance of Pioneer Balanced Fund is comparable
to the investment performance of your Safeco Fund. For the five year period
ended June 30, 2004, Class A shares of Pioneer Balanced Fund had an average
annual return of 1.34% compared to an average annual return of the Class A
shares and Investor shares of your Safeco Fund of 0.32% and 1.78%, respectively,
during the same period. In addition, the Trustees considered the track record of
Pioneer in managing equity and fixed income mutual funds.

     Third, the resources of Pioneer. At June 30, 2004, Pioneer managed over 62
investment companies and accounts with approximately $35 billion in assets.
Pioneer is part of the global asset management group of UniCredito Italiano
S.p.A., one of the largest banking groups in Italy, providing investment
management and financial services to mutual funds, institutions and other
clients. As of June 30, 2004, assets under management of UniCredito Italiano
S.p.A. were approximately $151 billion worldwide. Shareholders of your Safeco
Fund would become part of a significantly larger family of funds that offers a
more diverse array of investment options and enhanced shareholder account
options. The Pioneer family of mutual funds offers over 62 funds, including
domestic and international equity and fixed income funds and a money market fund
that will be available to your Safeco Fund's shareholders through exchanges. In
addition, Pioneer offers shareholders additional options for their accounts,
including the ability to transact and exchange shares over the telephone or
online and the ability to access account values and transaction history in all
of the shareholder's direct accounts in the Pioneer Funds over the telephone or
online.

     Fourth, Pioneer Balanced Fund's lower gross operating expenses and
Pioneer's commitment until the second anniversary of the Reorganization to limit
the expenses (excluding extraordinary expenses) of the Investor Class of Pioneer
Balanced Fund to 1.10% of average daily net assets. This expense ratio is below
the gross expenses of each class of shares of your Safeco Fund and is the same
or lower than expenses net of expense reimbursement of each class of shares of
your Safeco Fund.


     Fifth, the substantially larger size of Pioneer Balanced Fund offers
greater opportunity for diversification of the investment portfolio, which
should help to reduce risks.


     Sixth, shareholders who own shares in their name as of the closing of the
Reorganization (i.e., not in the name of a broker or other intermediary) and
maintain their account may purchase additional Class A shares of the
corresponding Pioneer Fund through such account in the future or may exchange
those shares for Class A shares of another Pioneer Fund or purchase Class A
share of another Pioneer Fund without paying any sales charge.


     Seventh, the Investor Class shares of Pioneer Balanced Fund received in the
Reorganization will provide Safeco Balanced Fund shareholders with exposure to
substantially the same investment product as they currently have.


     Pioneer and Symetra will pay all out of pocket expenses of the Safeco Funds
and the Pioneer Funds associated with the Reorganizations, including, but not
limited to: (1) the expenses associated with the preparation, printing and
mailing of any shareholder communications, including this joint Proxy
Statement/Prospectus, and any filings with the SEC and other governmental
authorities in connection with the Reorganizations; (2) the fees and expenses of
any proxy solicitation firm retained in connection with the Reorganizations; (3)
the legal fees and expenses incurred by the Safeco Funds in connection with the
Reorganizations; and (4) the Trustees' fees and out of pocket expenses incurred
as a result of the Reorganizations.

     The Trustees also considered that Pioneer and Symetra will benefit from the
Reorganization. See "Certain Agreements between Pioneer and Symetra."

     The Board of Trustees of Pioneer Balanced Fund also considered that the
Reorganization presents an excellent opportunity for the Pioneer Balanced Fund
to acquire investment assets without the obligation to pay commissions or other
transaction costs that a fund normally incurs when purchasing securities. This
opportunity provides an economic benefit to Pioneer Balanced Fund and its
shareholders.

     It is impossible to predict how many shares of Pioneer Balanced Fund will
actually be received and distributed by your Safeco Fund on the Reorganization
date. The table should not be relied upon to determine the amount of Pioneer
Balanced Fund's shares that will actually be received and distributed.


                      BOARD'S EVALUATION AND RECOMMENDATION


     For the reasons described above, the Trustees, including the Independent
Trustees, approved the Reorganization. In particular, the Trustees determined
that the Reorganization is in the best interests of your Safeco Fund. Similarly,
the board of trustees of Pioneer Balanced Fund, including its Independent
Trustees, approved the Reorganization. They also determined that the
Reorganization is in the best interests of Pioneer Balanced Fund.

     The Trustees recommend that the shareholders of your Safeco Fund vote FOR
the proposal to approve the Agreement and Plan of Reorganization.

                           Safeco Core Equity Fund and
                                  Pioneer Fund

                                  PROPOSAL 1(b)

                Approval of Agreement and Plan of Reorganization


                                     SUMMARY


     The following is a summary of more complete information appearing later in
this Proxy Statement/Prospectus or incorporated herein. You should read
carefully the entire Proxy Statement/Prospectus, including the form of Agreement
and Plan of Reorganization attached as EXHIBIT A-1 because they contain details
that are not in the summary.

     The Investor Class shares to be issued in the Reorganization will convert
to Class A shares after two years. Class A shares will have higher expenses per
share than Investor Class shares due to the Rule 12b-1 Plan. In addition,
although Pioneer has agreed to limit the expenses attributable to Investor Class
shares, Pioneer is not required to limit the expenses attributable to Class A
shares.

     In the table below, if a row extends across the entire table, the policy
disclosed applies to both your Safeco Fund and the Pioneer Fund.

Comparison of Principal Risks of Investing in the Funds

     Because each Fund has a similar investment objective, primary investment
policies and strategies, the Funds are subject to the same principal risks. You
could lose money on your investment in either Fund or not make as much as if you
invested elsewhere if:

     o    The stock market goes down (this risk may be greater in the short
          term)

     o    Value stocks fall out of favor with investors

     o    The Fund's assets remain undervalued or do not have the potential
          value originally expected

     o    Stocks selected for income do not achieve the same return as
          securities selected for capital growth


     The Investor Class shares to be issued in the Reorganization will convert
to Class A shares after two years. Class A shares will have higher expenses per
share than Investor Class shares due to the Rule 12b-1 Plan. In addition,
although Pioneer has agreed to limit the expenses attributable to Investor Class
shares, Pioneer is not required to limit the expenses attributable to Class A
shares.

Past Performance


     Set forth below is performance information for each Fund. The bar charts
show how each Fund's total return (not including any deduction for sales
charges) has varied from year to year for each full calendar year. The tables
show average annual total return (before and after taxes) for each Fund over
time for each class of shares (including deductions for sales charges) compared
with a broad-based securities market index. The bar charts give an indication of
the risks of investing in each Fund, including the fact that you could incur a
loss and experience volatility of returns year to year. Past performance before
and after taxes does not indicate future results.

     Pioneer Fund's Investor Class shares will not be outstanding prior to the
closing of the Reorganization and consequently have no performance history.
However, the performance record of the Investor Class would be modestly higher
than the performance of Class A shares due to the lower expenses applicable to
the Investor Class.


     The most recent portfolio manager's discussion of each Fund's performance
is attached as Exhibit D.


The Funds' Fees and Expenses

     Shareholders of both Funds 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 Fund. The expenses in the tables
appearing below are based on (i) for the Safeco Core Equity Fund, the expenses
of Safeco Core Equity Fund for the period ended December 31, 2003 and (ii) for
Pioneer Fund, the expenses of Pioneer Fund for the period ended December 31,
2003. Future expenses for all share classes may be greater or less.

- ----------
(1)  No sales load will apply to shares received in the Reorganization by
     shareholders of your Safeco Fund who become shareholders of record of
     Pioneer Fund through the Reorganization. In addition, shareholders of your
     Safeco Fund who own shares in their own name (i.e., not in the name of a
     broker or other intermediary) and maintain such account as of the closing
     of the Reorganization may purchase Class A Shares of Pioneer Fund or of any
     fund in the Pioneer family of funds through such account in the future
     without paying a sales charge.

(2)  As described above, SAM had contractually agreed to reimburse Safeco Core
     Equity Fund for certain Fund operating expenses (but not all of the
     operating expenses of the Fund) that exceeded the rate of 0.40% per annum
     of the Fund's average daily net assets. This arrangement included all fund
     operating expenses except management fees, Rule 12b-1 fees, brokerage
     commissions, interest, and extraordinary expenses.


(3)  Pioneer has agreed that through the second anniversary of the closing of
     the Reorganization, Pioneer will limit the expenses (excluding
     extraordinary expenses) of the Investor Class shares of Pioneer Fund to
     1.02% of average daily net assets.

(4)  There is a higher charge for international wire redemptions, which may vary
     by country or dollar amount.


(5)  A low balance fee is charged once each year in December for accounts with
     balances under $1,000 in your Safeco Fund.

(6)  Purchases of $1,000,000 or more of Class A shares of your Safeco Fund are
     not subject to a front-end sales charge, but a 1.00% deferred sales charge
     will apply to redemptions made in the first twelve months except with
     respect to participant-directed redemptions from qualified retirement
     plans.

(7)  The contingent deferred sales charge on Class B shares of your Safeco Fund
     reduces to zero after six years from purchase, and the Class B shares
     convert to Class A shares at that time.

(8)  The contingent deferred sales charge on Class C shares applies only to
     redemptions made in the first twelve months after purchase.



                                       29



(9)  The Investor Class shares to be issued in the Reorganization will convert
     to Class A shares after two years. Class A shares will have higher expenses
     per share than Investor Class shares due to the Rule 12b-1 Plan. In
     addition, although Pioneer has agreed to limit the expenses attributable to
     Investor Class shares, Pioneer is not required to limit the expenses
     attributable to Class A shares.

     The hypothetical example below helps you compare the cost of investing in
each Fund. It assumes that: (a) you invest $10,000 in each Fund for the time
periods shown, (b) you reinvest all dividends and distributions, (c) your
investment has a 5% return each year, (d) each Fund's gross operating expenses
remain the same, (e) the expense limitations are in effect for five years for
Safeco Core Equity Fund and two years for Pioneer Fund and (f) and the Investor
Class shares of Pioneer Fund convert to Class A shares after two years. The
examples are for comparison purposes only and are not a representation of either
fund's actual expenses or returns, either past or future.

Reasons for the Proposed Reorganization

     The Trustees believe that the proposed Reorganization is in the best
interests of Safeco Core Equity Fund. The Trustees considered the following
matters, among others, in approving the proposal.


     First, SAM, the investment adviser to the Fund until August 2, 2004, was
acquired by Symetra. Symetra informed the Trustees that it did not intend to
continue to provide investment advisory services to the Safeco Funds.
Consequently, a change in your Safeco Fund's investment adviser was necessary.

     Second, the historical investment performance of Pioneer Fund is higher
than your Safeco Fund's investment performance. For the one, five and 10 year
periods ended June 30, 2004, Class A shares of Pioneer Fund had an average
annual return of 18.13%; -1.14%; and 11.16% compared to an average annual
return of the Class A shares and Investor Class shares of 7.30% and 14.16% (one
year), -7.12% and -5.70% (five years) and 7.11% and 7.99% (ten years),
respectively, during the same period. In addition, the Trustees considered the
track record of Pioneer in managing equity and fixed income mutual funds.

     Third, the resources of Pioneer. At June 30, 2004, Pioneer managed over 62
investment companies and accounts with approximately $35 billion in assets.
Pioneer is part of the global asset management group of UniCredito Italiano
S.p.A., one of the largest banking groups in Italy, providing investment
management and financial services to mutual funds, institutional and other
clients. As of June 30, 2004, assets under management of UniCredito Italiano
S.p.A. were approximately $151 billion worldwide. Shareholders of your Safeco
Fund would become part of a significantly larger family of funds that offers a
more diverse array of investment options and enhanced shareholder account
options. The Pioneer family of mutual funds offers over 62 funds, including
domestic and international equity and fixed income funds and a money market
fund that will be available to your Safeco Fund's shareholders through
exchanges. In addition, Pioneer offers shareholders additional options for
their accounts, including the ability to transact and exchange shares over the
telephone or online and the ability to access account values and transaction
history in all of the shareholder's direct accounts in the Pioneer Funds over
the telephone or online.

     Fourth, Pioneer Fund's lower operating expenses and Pioneer's commitment
until the second anniversary of the Reorganization to limit the expenses
(excluding extraordinary expenses) of the Investor Class of Pioneer Fund to
1.02% of average daily net assets. This expense ratio is below or equal to the
gross expenses and expenses net of expense reimbursement of the class shares of
your Safeco Fund. While you will experience higher expenses once the Investor
Class shares convert to Class A shares after two years, the Class A expense
ratio for the most recent fiscal year was 1.09% of average daily net assets,
which was below the net expenses of the Class A shares of your Safeco Fund and
only four basis points above the net expenses of the Investor Class of your
Safeco Fund.


     Fifth, the substantially larger size of Pioneer Fund offers greater
opportunity for diversification of the investment portfolio, which should help
to reduce risks.


     Sixth, shareholders who own shares in their name as of the closing of the
Reorganization (i.e., not in the name of a broker or other intermediary) and
maintain their account may purchase additional Class A shares of the
corresponding Pioneer Fund through such account in the future or may exchange
those shares for Class A shares of another Pioneer Fund or purchase Class A
share of another Pioneer Fund without paying any sales charge.


     Seventh, the Investor Class shares of Pioneer Fund received in the
Reorganization will provide Safeco Core Equity Fund shareholders with exposure
to substantially the same investment product as they currently have.


     Pioneer and Symetra will pay all out of pocket expenses of the Safeco
Funds and the Pioneer Funds associated with the Reorganizations, including, but
not limited to: (1) the expenses associated with the preparation, printing and
mailing of any shareholder communications, including this joint Proxy
Statement/Prospectus, and any filings with the SEC and other governmental
authorities in connection with the Reorganizations; (2) the fees and expenses
of any proxy solicitation firm retained in connection with the Reorganizations;
(3) the legal fees and expenses incurred by the Safeco Funds in connection with
the Reorganizations; and (4) the Trustees' fees and out of pocket expenses
incurred as a result of the Reorganizations.

     The Trustees also considered that Pioneer and Symetra will benefit from
the Reorganization. See "Certain Agreements between Pioneer and Symetra."

     The Board of Trustees of Pioneer Fund also considered that the
Reorganization presents an excellent opportunity for the Pioneer Fund to
acquire investment assets without the obligation to pay commissions or other
transaction costs that a fund normally incurs when purchasing securities. This
opportunity provides an economic benefit to Pioneer Fund and its shareholders.

     It is impossible to predict how many shares of Pioneer Fund will actually
be received and distributed by your Safeco Fund on the Reorganization date. The
table should not be relied upon to determine the amount of Pioneer Fund's
shares that will actually be received and distributed.


                      BOARD'S EVALUATION AND RECOMMENDATION


     For the reasons described above, the Trustees, including the Independent
Trustees, approved the Reorganization. In particular, the Trustees determined
that the Reorganization is in the best interests of your Safeco Fund. Similarly,
the Board of Trustees of Pioneer Fund, including its Independent Trustees,
approved the Reorganization. They also determined that the Reorganization is in
the best interests of Pioneer Fund.

     The Trustees recommend that the shareholders of your Safeco Fund vote FOR
the proposal to approve the Agreement and Plan of Reorganization.

                       Pioneer Growth Opportunities Fund
                                 PROPOSAL 1(c)


                Approval of Agreement and Plan of Reorganization

                                    SUMMARY


     The following is a summary of more complete information appearing later in
this Proxy Statement/Prospectus or incorporated herein. You should read
carefully the entire proxy statement, including the form of Agreement and Plan
of Reorganization attached as EXHIBIT A-2 because they contain details that are
not in the summary.

     The Investor Class shares to be issued in the Reorganization will convert
to Class A shares after two years. Class A shares will have higher expenses per
share than Investor Class shares due to the Rule 12b-1 Plan. In addition,
although Pioneer has agreed to limit the expenses attributable to Investor Class
shares, Pioneer is not required to limit the expenses attributable to Class A
shares.

     In the table below, if a row extends across the entire table, the policy
disclosed applies to both your Safeco Fund and the Pioneer Fund.

                           Each Fund provides written notice to shareholders at least 60 days prior to any change to its

- ------------------------------------------------------------------------------------------------------------------------------------
 Primary investments       To achieve its investment objective, under normal circumstances, each Fund invests most of its

Comparison of Principal Risks of Investing in the Funds

     Because each Fund has a similar investment objective, primary investment
policies and strategies, the Funds are subject to the same principal risks. Even
though each Fund seeks capital growth, you could lose money on your investment
or not make as much as if you invested elsewhere if:

     o    The stock market goes down (this risk factor may be greater in the
          short term)

     o    Growth stocks fall out of favor with investors

     o    The Fund's investments do not have the growth potential originally
          expected

     o    The Fund's shares may be subject to frequent and more significant
          changes in value than the stock market in general due to the
          volatility of some of the smaller companies in which it invests

     o    During periods of market concern about inflation or deflation, some
          securities in which the Fund invests may become more volatile or
          decline in value

     Investing in non-U.S. issuers may involve unique risks compared to
investing in securities of U.S. issuers. These risks may include:

     o    Inadequate financial information

     o    Smaller, less liquid and more volatile markets

     o    Political and economic upheavals


     The fund also has risks associated with investing in small companies.
Compared to large companies, small companies, and the market for their equity
securities, are likely to:

     o    Be more sensitive to changes in the economy, earnings results and
          investor expectations

     o    Have more limited product lines and capital resources

     o    Experience sharper swings in market values

     o    Be harder to sell at the times and prices Pioneer thinks appropriate

     o    Offer greater potential for gain or loss

     The Investor Class shares to be issued in the Reorganization will convert
to Class A shares after two years. Class A shares will have higher expenses per
share than Investor Class shares due to the Rule 12b-1 Plan. In addition,
although Pioneer has agreed to limit the expenses attributable to Investor Class
shares, Pioneer is not required to limit the expenses attributable to Class A
shares.

(1)  No sales load will apply to shares received in the Reorganization by
     shareholders of your Safeco Fund who become shareholders of record of
     Pioneer Growth Opportunities Fund through the Reorganization. In addition,
     shareholders of your Safeco Fund who own shares in their own name (i.e.,
     not in the name of a broker or other intermediary) and maintain such
     account as of the closing of the Reorganization may purchase Class A shares
     of Pioneer Growth Opportunities Fund or of any fund in the Pioneer family
     of funds through such account in the future without paying a sales charge.

(2)  As described above, SAM had contractually agreed to reimburse Safeco Growth
     Opportunities Fund for certain Fund operating expenses (but not all of the
     operating expenses of the Fund) that exceeded the rate of 0.40% per annum
     of the Fund's average daily net assets.



                                       42


     This arrangement included all fund operating expenses except management
     fees, Rule 12b-1 fees, brokerage commissions, interest, and extraordinary
     expenses.


(3)  Pioneer has agreed that through the second anniversary of the closing of
     the Reorganization, Pioneer will limit the expenses (excluding
     extraordinary expenses) of the Investor Class shares of Pioneer Growth
     Opportunities Fund to 1.05% of average daily net assets.


(4)  There is a higher charge for international wire redemptions, which may vary
     by country or dollar amount.


(5)  A low balance fee is charged once in year in December for accounts with
     balances under $1,000 in your Safeco Fund.

(6)  Purchases of $1,000,000 or more of Class A shares of your Safeco Fund are
     not subject to a front-end sales charge, but a 1.00% deferred sales charge
     will apply to redemptions made in the first twelve months except with
     respect to participant-directed redemptions from qualified retirement
     plans.

(7)  The contingent deferred sales charge on Class B shares of your Safeco Fund
     reduces to zero after six years from purchase, and the Class B shares
     convert to Class A shares at that time.


(8)  The contingent deferred sales charge on Class C shares applies only to
     redemptions made in the first twelve months after purchase.

(9)  The Investor Class shares to be issued in the Reorganization will convert
     to Class A shares after two years. Class A shares will have higher expenses
     per share than Investor Class shares due to the Rule 12b-1 Plan. In
     addition, although Pioneer has agreed to limit the expenses attributable to
     Investor Class shares, Pioneer is not required to limit the expenses
     attributable to Class A shares. Class A shares do not currently have an
     expense limitation and may be subject to higher total operating expenses.


     The hypothetical example below helps you compare the cost of investing in
each Fund. It assumes that: (a) you invest $10,000 in each Fund for the time
periods shown, (b) you reinvest all dividends and distributions, (c) your
investment has a 5% return each year, (d) each Fund's and Pioneer Growth
Opportunities Fund's gross operating expenses remain the same, (e) the expense
limitations are in effect for five years for Safeco Growth Opportunities Fund
and two years for Pioneer Growth Opportunities Fund and (f) and the Investor
Class shares of Pioneer Growth Opportunities Fund convert to Class A shares
after two years. The examples are for comparison purposes only and are not a
representation of either Fund's actual expenses or returns, either past or
future.

Reasons for the Proposed Reorganization


     The Trustees believe that the proposed Reorganization is in the best
interests of Safeco Growth Opportunities Fund. The Trustees considered the
following matters, among others, in approving the proposal.

     First, SAM, the investment adviser to the Safeco Fund until August 2, 2004,
was acquired by Symetra. Symetra informed the Trustees that it did not intend to
continue to provide investment advisory services to the Safeco Funds.
Consequently, a change in your Safeco Fund's investment adviser was necessary.

     Second, the resources of Pioneer. At June 30, 2004, Pioneer managed over 62
investment companies and accounts with approximately $35 billion in assets.
Pioneer is part of the global asset management group of UniCredito Italiano
S.p.A., one of the largest banking groups in Italy, providing investment
management and financial services to mutual funds, institutions and other
clients. As of June 30, 2004, assets under management of UniCredito Italiano
S.p.A. were approximately $151 billion worldwide. Shareholders of your Safeco
Fund would become part of a significantly larger family of funds that offers a
more diverse array of investment options and enhanced shareholder account
options. The Pioneer family of mutual funds offers over 62 funds, including
domestic and international equity and fixed income funds and a money market fund
that will be available to your Safeco Fund's shareholders through exchanges. In
addition, Pioneer offers shareholders additional options for their accounts,
including the ability to transact and exchange shares over the telephone or
online and the ability to access account values and transaction history in all
of the shareholder's direct accounts in the Pioneer Funds over the telephone or
online.

     Third, Pioneer's commitment until the second anniversary of the
Reorganization to limit the expenses (excluding extraordinary expenses) of the
Investor Class of Pioneer Growth Opportunities Fund to 1.05% of average daily
net assets. This expense ratio is no higher than both the gross expenses and
expenses net of expense reimbursement of the Investor Class shares of your
Safeco Fund. Although you will experience higher expenses once the Investor
Class shares convert to Class A shares after two years, your expenses will
remain the same until the second anniversary of the Reorganization.

     Fourth, shareholders who own shares in their name as of the closing of the
Reorganization (i.e., not in the name of a broker or other intermediary) and
maintain their account may purchase additional Class A shares of the
corresponding Pioneer Fund through such account in the future or may exchange
those shares for Class A shares of another Pioneer Fund or purchase Class A
share of another Pioneer Fund without paying any sales charge.

     Fifth, the Investor Class shares of Pioneer Growth Opportunities Fund
received in the Reorganization will provide Safeco Growth Opportunities Fund
shareholders with exposure to substantially the same investment product as they
currently have.

     Pioneer and Symetra will pay all out of pocket expenses of the Safeco Funds
and the Pioneer Funds associated with the Reorganizations, including, but not
limited to: (1) the expenses associated with the preparation, printing and
mailing of any shareholder communications, including this joint Proxy
Statement/Prospectus, and any filings with the SEC and other governmental
authorities in connection with the Reorganizations; (2) the fees and expenses of
any proxy solicitation firm retained in connection with the Reorganizations; (3)
the legal fees and expenses incurred by the Safeco Funds in connection with the
Reorganizations; and (4) the Trustees' fees and out of pocket expenses incurred
as a result of the Reorganizations.

     The Trustees also considered that Pioneer and Symetra will benefit from the
Reorganization. See "Certain Agreements between Pioneer and Symetra."

     The Trustees of Pioneer Growth Opportunities Fund also considered that the
Reorganization presents an excellent opportunity for the Pioneer Growth
Opportunities Fund to acquire investment assets without the obligation to pay
commissions or other transaction costs that a fund normally incurs when
purchasing securities. This opportunity provides an economic benefit to Pioneer
Growth Opportunities Fund and its shareholders.

     It is impossible to predict how many shares of Pioneer Growth Opportunities
Fund will actually be received and distributed by your Safeco Fund on the
Reorganization date. The table should not be relied upon to determine the amount
of Pioneer Growth Opportunities Fund's shares that will actually be received and
distributed.

                      BOARD'S EVALUATION AND RECOMMENDATION

     For the reasons described above, the Trustees, including the Independent
Trustees, approved the Reorganization. In particular, the Trustees determined
that the Reorganization is in the best interests of your Safeco Fund. Similarly,
the Board of Trustees of Pioneer Growth Opportunities Fund, including its
Independent Trustees, approved the Reorganization. They also determined that the
Reorganization is in the best interests of Pioneer Growth Opportunities Fund.

     The Trustees recommend that the shareholders of your Safeco Fund vote FOR
the proposal to approve the Agreement and Plan of Reorganization.

                        Pioneer International Equity Fund

                                  PROPOSAL 1(d)


                Approval of Agreement and Plan of Reorganization

                                     SUMMARY


     The following is a summary of more complete information appearing later in
this Proxy Statement/Prospectus or incorporated herein. You should read
carefully the entire proxy statement, including the form of Agreement and Plan
of Reorganization attached as EXHIBIT A-1 because they contain details that are
not in the summary.

     The Investor Class shares to be issued in the Reorganization will convert
to Class A shares after two years. Class A shares will have higher expenses per
share than Investor Class shares due to the Rule 12b-1 Plan. In addition,
although Pioneer has agreed to limit the expenses attributable to Investor Class
shares, Pioneer is not required to limit the expenses attributable to Class A
shares.

     In the table below, if a row extends across the entire table, the policy
disclosed applies to both your Safeco Fund and the Pioneer Fund.

Comparison of Principal Risks of Investing in the Funds

     Because each Fund has a similar investment objective, primary investment
policies and strategies, the Funds are subject to the same principal risks. You
could lose money on your investment in either Fund or not make as much as if you
invested elsewhere if:

     o    The non-U.S. stock markets go down or perform poorly relative to other
          investments (this risk may be greater in the short term)

     o    Equity securities of non-U.S. issuers or growth stocks fall out of
          favor with investors

     o    The Fund's investments do not have the growth potential originally
          expected

     Investing in non-U.S. issuers may involve unique risks compared to
investing in securities of U.S. issuers. Some of these risks do not apply to
larger, more developed markets. These risks are more pronounced to the extent
the Fund invests in issuers in countries with emerging markets or if the fund
invests significantly in one 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, Pioneer may not be able to sell the Fund's portfolio
          securities at times, in amounts and at prices it considers reasonable

     o    Adverse effect of currency exchange rates or controls on the value of
          the Fund's investments

     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 and social developments may adversely affect the
          securities markets

     o    Withholding and other non-U.S. taxes may decrease the Fund's return

     Investments in the Funds are not bank deposits and are not insured or
guaranteed by the Federal Deposit Insurance Corporation or any other government
agency. You could lose money by investing in either Fund.


     The Investor Class Shares to be issued in the Reorganization will convert
to Class A shares after two years. Class A shares will have higher expenses per
share than Investor Class Shares due to the Rule 12b-1 Plan. In addition,
although Pioneer has agreed to limit the expenses attributable to Investor Class
shares, Pioneer is not required to limit the expenses attributable to Class A
shares. The current expense limitation agreement for Class A shares is in effect
until August 31, 2005. There can be no assurance that Pioneer will extend the
expense limitation agreement for its Class A shares after August 31, 2005.

Past Performance

     Pioneer International Equity Fund's Investor Class shares will not be
outstanding prior to the closing of the Reorganization and consequently have no
performance history. However, the performance record of the Investor Class would
be modestly higher than the performance of Class A shares due to the lower
expenses applicable to the Investor Class.

     The most recent portfolio manager's discussion of each Fund's performance
is attached as Exhibit D.

(1)  No sales load will apply to shares received in the Reorganization by
     shareholders of your Safeco Fund who become shareholders of record of
     Pioneer International Equity Fund through the Reorganization. In addition,
     shareholders of your Safeco Fund who own shares in their own name (i.e.,
     not in the name of a broker or other intermediary) and maintain such
     account as of the closing of the Reorganization may purchase Class A shares
     of Pioneer International Equity Fund or of any fund in the Pioneer family
     of funds through such account in the future without paying a sales charge.

(2)  As described above, SAM had contractually agreed to reimburse Safeco
     International Stock Fund for certain Fund operating expenses (but not all
     of the operating expenses of the Fund) that exceeded the rate of 0.40% per
     annum of the Fund's average daily net assets. This arrangement included all
     fund operating expenses except management fees, Rule 12b-1 fees, brokerage
     commissions, interest, and extraordinary expenses. In 2003, SAM
     additionally began voluntarily reimbursing the Fund to the extent that the
     total expenses of the Institutional Class exceeded the rate of 1.10% per
     annum of the Fund's average daily net assets for Institutional Class. The
     above table reflects "contractual" expense reimbursements from SAM, if any,
     but does not reflect "voluntary" expense reimbursements by SAM.


(3)  Pioneer has agreed that through the second anniversary of the closing of
     the Reorganization, Pioneer will limit the expenses (excluding
     extraordinary expenses) of the Investor Class shares of Pioneer
     International Equity Fund to 1.40% of average daily net assets.

(4)  There is a higher charge for international wire redemptions, which may vary
     by country or dollar amount.


(5)  A low balance fee is charged once each year in December for accounts with
     balances under $1,000 in your Safeco Fund.

(6)  Purchases of $1,000,000 or more of Class A shares of your Safeco Fund are
     not subject to a front-end sales charge, but a 1.00% deferred sales charge
     will apply to redemptions mad in the first twelve months except with
     respect to participant-directed redemptions from qualified retirement
     plans.

(7)  The contingent deferred sales charge on Class B shares of your Safeco Fund
     reduces to zero after six years from purchase, and the Class B shares
     covert to Class A shares at that time.

(8)  The contingent deferred sales charge on Class C shares applies only to
     redemptions made in the first twelve months after purchase.



                                       56



     The hypothetical example below helps you compare the cost of investing in
each Fund. It assumes that: (a) you invest $10,000 in each Fund for the time
periods shown, (b) you reinvest all dividends and distributions, (c) your
investment has a 5% return each year, (d) each Fund's gross operating expenses
remain the same, (e) the expense limitations are in effect for five years for
Safeco International Stock Fund and two years for Pioneer International Equity
Fund and (f) and the Investor Class shares of Pioneer International Equity Fund
convert to Class A shares after two years, without giving effect to any expense
limitation upon conversion. The examples are for comparison purposes only and
are not a representation of either Fund's actual expenses or returns, either
past or future.

Reasons for the Proposed Reorganization

     The Trustees believe that the proposed Reorganization is in the best
interests of Safeco International Stock Fund. The Trustees considered the
following matters, among others, in approving the proposal.


     First, SAM, the investment adviser to the Safeco Fund until August 2, 2004,
was acquired by Symetra. Symetra informed the Trustees that it did not intend to
continue to provide investment advisory services to the Safeco Funds.
Consequently, a change in your Safeco Fund's investment management was
necessary.

     Second, the resources of Pioneer. At June 30, 2004, Pioneer managed over 62
investment companies and accounts with approximately $35 billion in assets.
Pioneer is part of the global asset management group of UniCredito Italiano
S.p.A., one of the largest banking groups in Italy, providing investment
management and financial services to mutual funds, institutions and other
clients. As of June 30, 2004, assets under management of UniCredito Italiano
S.p.A. were approximately $151 billion worldwide. Shareholders of your Safeco
Fund would become part of a significantly larger family of funds that offers a
more diverse array of investment options and enhanced shareholder account
options. The Pioneer family of mutual funds offers over 62 funds, including
domestic and international equity and fixed income funds and a money market fund
that will be available to your Safeco Fund's shareholders through exchanges. In
addition, Pioneer offers shareholders additional options for their accounts,
including the ability to transact and exchange shares over the telephone or
online and the ability to access account values and transaction history in all
of the shareholder's direct accounts in the Pioneer Funds over the telephone or
online.

     Third, Pioneer's commitment until the second anniversary of the
Reorganization to limit the expenses (excluding extraordinary expenses) of the
Investor Class of Pioneer International Equity Fund to 1.40% of average daily
net assets. The estimated expenses of the Investor Class of Pioneer
International Equity Fund are lower than or equal to both the gross and net
expenses after contractual reimbursements only of each class of shares of your
Safeco Fund.

     Fourth, shareholders who own shares in their name as of the closing of the
Reorganization (i.e., not in the name of a broker or other intermediary) and
maintain their account may purchase additional Class A shares of the
corresponding Pioneer Fund through such account in the future or may exchange
those shares for Class A shares of another Pioneer Fund or purchase Class A
share of another Pioneer Fund without paying any sales charge.


     Fifth, the Investor Class shares of Pioneer International Equity Fund
received in the Reorganization will provide Safeco International Stock Fund
shareholders with exposure to substantially the same investment product as they
currently have.


     Pioneer and Symetra will pay all out of pocket expenses of the Safeco Funds
and the Pioneer Funds associated with the Reorganizations, including, but not
limited to: (1) the expenses associated with the preparation, printing and
mailing of any shareholder communications, including this joint Proxy
Statement/Prospectus, and any filings with the SEC and other governmental
authorities in connection with the Reorganizations; (2) the fees and expenses of
any proxy solicitation firm retained in connection with the Reorganizations; (3)
the legal fees and expenses incurred by the Safeco Funds in connection with the
Reorganizations; and (4) the Trustees' fees and out of pocket expenses incurred
as a result of the Reorganizations.

     The Trustees also considered that Pioneer and Symetra will benefit from the
Reorganization. See "Certain Agreements between Pioneer and Symetra."

     The Board of Trustees of Pioneer International Equity Fund also considered
that the Reorganization presents an excellent opportunity for the Pioneer
International Equity Fund to acquire investment assets without the obligation to
pay commissions or other transaction costs that a fund normally incurs when
purchasing securities. This opportunity provides an economic benefit to Pioneer
International Equity Fund and its shareholders.

     It is impossible to predict how many shares of Pioneer International Equity
Fund will actually be received and distributed by your Safeco Fund on the
Reorganization date. The table should not be relied upon to determine the amount
of Pioneer International Equity Fund's shares that will actually be received and
distributed.

                      BOARD'S EVALUATION AND RECOMMENDATION

     For the reasons described above, the Trustees, including the Independent
Trustees, approved the Reorganization. In particular, the Trustees determined
that the Reorganization is in the best interests of your Safeco Fund. Similarly,
the Board of Trustees of Pioneer International Equity Fund, including its
Independent Trustees, approved the Reorganization. They also determined that the
Reorganization is in the best interests of Pioneer International Equity Fund.

     The Trustees recommend that the shareholders of your Safeco Fund vote FOR
the proposal to approve the Agreement and Plan of Reorganization.

                              Pioneer Growth Shares

                                  PROPOSAL 1(e)


                Approval of Agreement and Plan of Reorganization

                                     SUMMARY


     The following is a summary of more complete information appearing later in
this Proxy Statement/Prospectus or incorporated herein. You should read
carefully the entire proxy statement, including the form of Agreement and Plan
of Reorganization attached as EXHIBIT A-1 because they contain details that are
not in the summary.

     The Investor Class shares to be issued in the Reorganization will convert
to Class A shares after two years. Class A shares will have a higher expenses
per share than Investor Class shares due to the Rule 12b-1 Plan. In addition,
although Pioneer has agreed to limit the expenses attributable to Investor Class
shares, Pioneer is not required to limit the expenses attributable to Class A
shares.

     In the table below, if a row extends across the entire table, the policy
disclosed applies to both your Safeco Fund and the Pioneer Fund.

Comparison of Principal Risks of Investing in the Funds

     Because each Fund has a similar investment objective, primary investment
policies and strategies, the Funds are subject to the same principal risks. You
could lose money on your investment in either Fund or not make as much as if you
invested elsewhere if:

     o    The stock market goes down (this risk may be greater in the
          short-term)

     o    Growth stocks fall out of favor with investors

     o    The Fund's investments do not have the growth potential originally
          expected

     Investing in non-U.S. issuers may involve unique risks compared to
investing in securities of U.S. issuers. 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 small, less liquid and more volatile. In a
          changing market, Pioneer might not be able to sell the Fund's
          portfolio securities at times, in amounts and at prices it considers
          reasonable

     o    Adverse effect of currency exchange rates or controls on the value of
          the Fund's investments

     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 and social developments may adversely affect the
          securities markets

     o    Withholding and other non-U.S. taxes may decrease the Fund's return


     The Investor Class shares to be issued in the Reorganization will convert
to Class A shares after two years. Class A shares will have higher expenses per
share than Investor Class shares due to the Rule 12b-1 Plan. In addition,
although Pioneer has agreed to limit the expenses attributable to Investor Class
shares, Pioneer is not required to limit the expenses attributable to Class A
shares.

Past Performance


     Set forth below is performance information for each Fund. The bar charts
show how each Fund's total return (not including any deduction for sales
charges) has varied from year to year for each full calendar year. The tables
show average annual total return (before and after taxes) for each Fund over
time for each class of shares (including deductions for sales charges) compared
with a broad-based securities market index. The bar charts give an indication of
the risks of investing in each Fund, including the fact that you could incur a
loss and experience volatility of returns year to year. Past performance before
and after taxes does not indicate future results.

     Pioneer Growth Shares' Investor Class shares will not be outstanding prior
to the closing of the Reorganization and consequently have no performance
history. However, the performance record of the Investor Class would be modestly
higher than the performance of Class A shares due to the lower expenses
applicable to the Investor Class.


     The most recent portfolio manager's discussion of each Fund's performance
is attached as Exhibit D.

(1)  No sales load will apply to shares received in the Reorganization by
     shareholders of your Safeco Fund who become shareholders of record of
     Pioneer Growth Shares through the Reorganization. In addition, shareholders
     of your Safeco Fund who own shares in their own name (i.e., not in the name
     of a broker or other intermediary) and maintain such account as of the
     closing of the Reorganization may purchase Class A Shares of Pioneer Growth
     Shares or of any fund in the Pioneer family of funds through such account
     in the future without paying a sales charge.

(2)  In 2003, SAM began voluntarily reimbursing the Fund to the extent that its
     total expenses exceeded the rate of 1.40% per annum of the Fund's average
     daily net assets for Class A shares, 2.15% per annum for Class B and Class
     C shares, and 1.15% per annum for Investor Class shares. The above table
     reflects "contractual" expense reimbursements by SAM, if any, but does not
     reflect "voluntary" expense reimbursements by SAM.


(3)  Pioneer has agreed that through the second anniversary of the closing of
     the Reorganization, Pioneer will limit the expenses (excluding
     extraordinary expenses) of the Investor Class shares of Pioneer Growth
     Shares to 1.15% of average daily net assets

(4)  There is a higher charge for international wire redemptions, which may vary
     by country or dollar amount.


(5)  A low balance fee is charged once each year in December for accounts with
     balances under $1,000 in your Safeco Fund.

(6)  Purchases of $1,000,000 or more of Class A shares of your Safeco Fund are
     not subject to a front-end sales charge, but a 1.00% deferred sales charge
     will apply to redemptions made in the first twelve months except with
     respect to participant-directed redemptions from qualified retirement
     plans.



                                       70



(7)  The contingent deferred sales charge on Class B shares of your Safeco Fund
     reduces to zero after six years from purchase, and the Class B shares
     convert to Class A shares at that time.


(8)  The contingent deferred sales charge on Class C shares applies only to
     redemptions made in the first twelve months after purchase.

(9)  The Investor Class shares to be issued in the Reorganization will convert
     to Class A shares after two years. Class A shares will have higher expenses
     per share than Investor Class shares due to the Rule 12b-1 Plan. In
     addition, although Pioneer has agreed to limit the expenses attributable to
     Investor Class shares, Pioneer is not required to limit the expenses
     attributable to Class A shares. Class A shares do not currently have an
     expense limitation and may be subject to higher total operating expenses.


     The hypothetical example below helps you compare the cost of investing in
each Fund. It assumes that: (a) you invest $10,000 in each Fund for the time
periods shown, (b) you reinvest all dividends and distributions, (c) your
investment has a 5% return each year, (d) each Fund's gross operating expenses
remain the same, (e) the expense limitations are in effect for one year for
Safeco Large-Cap Growth Fund and two years for Pioneer Growth Shares and (f) and
the Investor Class shares of Pioneer Growth Shares convert to Class A shares
after two years. The examples are for comparison purposes only and are not a
representation of either Fund's actual expenses or returns, either past or
future.

Reasons for the Proposed Reorganization


     The Trustees believe that the proposed Reorganization is in the best
interests of Safeco Large-Cap Growth Fund. The Trustees considered the following
matters, among others, in approving the proposal.

     First, SAM, the investment adviser to the Safeco Fund until August 2, 2004,
was acquired by Symetra. Symetra informed the Trustees that it did not intend to
continue to provide investment advisory services to the Safeco Funds.
Consequently, a change in your Safeco Fund's investment adviser was necessary.

     Second, Pioneer Growth Shares has a strong short term performance record
and a substantially longer performance history. For the one year period ended
June 30, 2004, Class A shares of Pioneer Growth Shares had an average annual
return of 9.31% compared to an average annual return of the Class A shares and
Investor Class shares of 4.25% and 10.77%, respectively, during the same
periods. In addition, the Trustees considered the track record of Pioneer in
managing equity and fixed income mutual funds.

     Third, the resources of Pioneer. At June 30, 2004, Pioneer managed over 62
investment companies and accounts with approximately $35 billion in assets.
Pioneer is part of the global asset management group of UniCredito Italiano
S.p.A., one of the largest banking groups in Italy, providing investment
management and financial services to mutual funds, institutions and other
clients. As of June 30, 2004, assets under management of UniCredito Italiano
S.p.A. were approximately $151 billion worldwide. Shareholders of your Safeco
Fund would become part of a significantly larger family of funds that offers a
more diverse array of investment options and enhanced shareholder account
options. The Pioneer family of mutual funds offers over 62 funds, including
domestic and international equity and fixed income funds and a money market fund
that will be available to your Safeco Fund's shareholders through exchanges. In
addition, Pioneer offers shareholders additional options for their accounts,
including the ability to transact and exchange shares over the telephone or
online and the ability to access account values and transaction history in all
of the shareholder's direct accounts in the Pioneer Funds over the telephone or
online.

     Fourth, Pioneer Growth Shares' lower operating expenses and Pioneer's
commitment until the second anniversary of the Reorganization to limit the
expenses (excluding extraordinary expenses) of the Investor Class of Pioneer
Growth Shares to 1.15% of average daily net assets. The estimated expense ratio
of the Investor Class of Pioneer Growth Shares is lower than or equal to the
gross and net expense ratio of each class of shares of your Safeco Fund. The
expense limitation applicable to Investor Class Shares of Pioneer Growth Shares
is equivalent to the voluntary expense limit applicable to the Investor Class
shares of your Safeco Fund, lower than the limit on all the other classes of
your Safeco Fund, and Pioneer has contractually agreed to keep that limit in
place for two years while the expense limit applicable to your Safeco Fund could
be terminated at any time. While you may experience higher expenses once the
Investor Class shares convert to Class A shares after two years, the Class A
shares expense ratio for the most recent fiscal year was 1.45% of average daily
net assets, which was below the gross expenses of Class A shares of your Safeco
Fund.


     Fifth, the substantially larger size of Pioneer Growth Shares offers
greater opportunity for diversification of the investment portfolio, which
should help to reduce risks.


     Sixth, shareholders who own shares in their name as of the closing of the
Reorganization (i.e., not in the name of a broker or other intermediary) and
maintain their account may purchase additional Class A shares of the
corresponding Pioneer Fund through such account in the future or may exchange
those shares for Class A shares of another Pioneer Fund or purchase Class A
shares of another Pioneer Fund without paying any sales charge.

     Seventh, the Investor Class shares of Pioneer Growth Shares received in the
Reorganization will provide Safeco Large-Cap Growth Fund shareholders with
exposure to substantially the same investment product as they currently have.

     Pioneer and Symetra will pay all out of pocket expenses of the Safeco Funds
and the Pioneer Funds associated with the Reorganizations, including, but not
limited to: (1) the expenses associated with the preparation, printing and
mailing of any shareholder communications, including this joint Proxy
Statement/Prospectus, and any filings with the SEC and other governmental
authorities in connection with the Reorganizations; (2) the fees and expenses of
any proxy solicitation firm retained in connection with the Reorganizations; (3)
the legal fees and expenses incurred by the Safeco Funds in connection with the
Reorganizations; and (4) the Trustees' fees and out of pocket expenses incurred
as a result of the Reorganizations.

     The Trustees also considered that Pioneer and Symetra will benefit from the
Reorganization. See "Certain Agreements between Pioneer and Symetra."

     The Board of Trustees of Pioneer Growth Shares also considered that the
Reorganization presents an excellent opportunity for the Pioneer Growth Shares
to acquire investment assets without the obligation to pay commissions or other
transaction costs that a fund normally incurs when purchasing securities. This
opportunity provides an economic benefit to Pioneer Growth Shares and its
shareholders.



                                       72



     Pioneer offers several growth oriented equity funds. From time to time,
Pioneer considers recommending to trustees and shareholders the combination of
certain Pioneer funds that have similar investment strategies and where the
Pioneer funds may benefit from economies of scale. It is possible that Pioneer
will recommend the combination of Pioneer Growth Shares with another Pioneer
fund in the future. If such a recommendation is made, there can be no assurance
that the trustees or shareholders of the relevant funds would approve the
transaction.


                                 CAPITALIZATION


     The following table sets forth the capitalization of each Fund as of
September 30, 2004, and pro forma combined Fund as of September 30, 2004.

     It is impossible to predict how many shares of Pioneer Growth Shares will
actually be received and distributed by your Safeco Fund on the Reorganization
date. The table should not be relied upon to determine the amount of Pioneer
Growth Shares' shares that will actually be received and distributed.


                      BOARD'S EVALUATION AND RECOMMENDATION


     For the reasons described above, the Trustees, including the Independent
Trustees, approved the Reorganization. In particular, the Trustees determined
that the Reorganization is in the best interests of your Safeco Fund. Similarly,
the Board of Trustees of Pioneer Growth Shares, including its Independent
Trustees, approved the Reorganization. They also determined that the
Reorganization is in the best interests of Pioneer Growth Shares.

     The Trustees recommend that the shareholders of your Safeco Fund vote FOR
the proposal to approve the Agreement and Plan of Reorganization.

                         Safeco Large-Cap Value Fund and
                               Pioneer Value Fund

                                  PROPOSAL 1(f)


                Approval of Agreement and Plan of Reorganization

                                     SUMMARY


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

     The Investor Class shares to be issued in the Reorganization will convert
to Class A shares after two years. Class A shares will have higher expenses per
share than Investor Class shares due to the Rule 12b-1 Plan. In addition,
although Pioneer has agreed to limit the expenses attributable to Investor Class
shares, Pioneer is not required to limit the expenses attributable to Class A
shares.

     In the table below, if a row extends across the entire table, the policy
disclosed applies to both your Safeco Fund and the Pioneer Fund.

Comparison of Principal Risks of Investing in the Funds

     Because each Fund has a similar investment objective, primary investment
policies and strategies, the Funds are subject to the same principal risks. You
could lose money on your investment in either Fund or not make as much as if you
invested elsewhere if:

     o    Stock market goes down (this risk may be greater in the short-term)

     o    Value stocks fall out of favor with investors

     o    The Fund's assets remain undervalued or do not have the potential
          value originally expected

     o    Stocks selected for income do not achieve the same return as
          securities selected for capital appreciation Investments in the Funds
          are not bank deposits and are not insured or guaranteed by the Federal
          Deposit Insurance Corporation or any other government agency. You
          could lose money by investing in either Fund.


     The Investor Class Shares to be issued in the Reorganization will convert
to Class A shares after two years. Class A shares will have higher expenses per
share than Investor Class Shares due to the Rule 12b-1 Plan. In addition,
although Pioneer has agreed to limit the expenses attributable to Investor Class
shares, Pioneer is not required to limit the expenses attributable to Class A
shares.

Past Performance


     Set forth below is performance information for each Fund. The bar charts
show how each Fund's total return (not including any deduction for sales
charges) has varied from year to year for each full calendar year. The tables
show average annual total return (before and after taxes) for each Fund over
time for each class of shares (including deductions for sales charges) compared
with a broad-based securities market index. The bar charts give an indication of
the risks of investing in each Fund, including the fact that you could incur a
loss and experience volatility of returns year to year. Past performance before
and after taxes does not indicate future results.

     Pioneer Value Fund's Investor Class shares will not be outstanding prior to
the closing of the Reorganization and consequently have no performance history.
However, the performance record of the Investor Class would be modestly higher
than the performance of Class A, B and C shares due to the lower expenses
applicable to the Investor Class.


     The most recent portfolio manager's discussion of each Fund's performance
is attached as Exhibit D.


The Funds' Fees and Expenses


     Shareholders of both Funds 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 Fund. The expenses in the tables
appearing below are based on (i) for your Safeco Fund, the expenses of your
Safeco Fund for the period ended December 31, 2003 and (ii) for Pioneer Value
Fund, the expenses of Pioneer Value Fund for the period ended June 30, 2003.
Future expenses for all share classes may be greater or less.

(1)  No sales load will apply to shares received in the Reorganization by
     shareholders of your Safeco Fund who become shareholders of record of
     Pioneer Value Fund through the Reorganization. In addition, shareholders of
     your Safeco Fund who own shares in their own name (i.e., not in the name of
     a broker or other intermediary) and maintain such account as of the closing
     of the Reorganization may purchase Class A Shares of Pioneer Value Fund or
     of any Fund in the Pioneer family of funds through such account in the
     future without paying a sales charge.

(2)  As described above, SAM had contractually agreed to reimburse Safeco
     Large-Cap Value Fund for certain Fund operating expenses (but not all of
     the operating expenses of the Fund) that exceeded the rate of 0.40% per
     annum of the Fund's average daily net assets. This arrangement included all
     fund operating expenses except management fees, Rule 12b-1 fees, brokerage
     commissions, interest, and extraordinary expenses.


(3)  Pioneer has agreed that through the second anniversary of the closing of
     the Reorganization, Pioneer will limit the expenses (excluding
     extraordinary expenses) of the Investor Class shares of Pioneer Value Fund
     to 1.10% of average daily net assets.

(4)  There is a higher charge for international wire redemptions, which may vary
     by country or dollar amount.


(5)  A low balance fee is charged once in year in December for accounts with
     balances under $1,000 in your Safeco Fund.

(6)  Purchases of $1,000,000 or more of Class A shares of your Safeco Fund are
     not subject to a front-end sales charge, but a 1.00% deferred sales charge
     will apply to redemptions made in the first twelve months except with
     respect to participant-directed redemptions from qualified retirement
     plans.

(7)  The contingent deferred sales charge on Class B shares of your Safeco Fund
     reduces to zero after six years from purchase, and the Class B shares
     convert to Class A shares at that time.


(8)  The contingent deferred sales charge on Class C shares applies only to

(9)  The Investor Class shares to be issued in the Reorganization will convert
     to Class A shares after two years. Class A shares will have higher expenses
     per share than Investor Class shares due to the Rule 12b-1 Plan. In
     addition, although Pioneer has agreed to limit the expenses attributable to
     Investor Class shares, Pioneer is not required to limit the expenses
     attributable to Class A shares. Class A shares do not currently have an
     expense limitation.

     The hypothetical example below helps you compare the cost of investing in
each Fund. It assumes that: (a) you invest $10,000 in each Fund for the time
periods shown, (b) you reinvest all dividends and distributions, (c) your
investment has a 5% return each year, (d) each Fund's gross operating expenses
remain the same, (e) the expense limitations are in effect for five years for
Safeco Large-Cap Value Fund and two years for Pioneer Value Fund and (f) and the
Investor Class shares of Pioneer Value Fund convert to Class A shares after two
years. The examples are for comparison purposes only and are not a
representation of either Fund's actual expenses or returns, either past or
future.

Reasons for the Proposed Reorganization


     The Trustees believe that the proposed Reorganization is in the best
interests of Safeco Large-Cap Value Fund. The Trustees considered the following
matters, among others, in approving the proposal.

     First, SAM, the investment adviser to the Safeco Fund until August 2, 2004,
was acquired by Symetra. Symetra informed the Trustees that it did not intend to
continue to provide investment advisory services to the Safeco Funds.
Consequently, a change in your Safeco Fund's investment adviser was necessary.

     Second, Pioneer Value Fund's short and long-term performance record is
superior to the performance record of your Safeco Fund. For the one, five and
ten year periods ended June 30, 2004, Class A shares of Pioneer Value Fund had
an average annual return of 20.04%, 3.24%, and 8.43%, respectively, compared to
an average annual return of the Class A shares and Investor Class shares of
11.80% and 18.91% (one year) -3.11% and -1.71% (five year) and 6.63% and 7.52%
(ten year), respectively, during the same period. In addition, the Trustees
considered the track record of Pioneer in managing equity and fixed income
mutual funds.

     Third, the resources of Pioneer. At June 30, 2004, Pioneer managed over 62
investment companies and accounts with approximately $35 billion in assets.
Pioneer is part of the global asset management group of UniCredito Italiano
S.p.A., one of the largest banking groups in Italy, providing investment
management and financial services to mutual funds, institutions and other
clients. As of June 30, 2004, assets under management of UniCredito Italiano
S.p.A. were approximately $151 billion worldwide. Shareholders of your Safeco
Fund would become part of a significantly larger family of funds that offers a
more diverse array of investment options and enhanced shareholder account
options. The Pioneer family of mutual funds offers over 62 funds, including
domestic and international equity and fixed income funds and a money market fund
that will be available to your Safeco Fund's shareholders through exchanges. In
addition, Pioneer offers shareholders additional options for their accounts,
including the ability to transact and exchange shares over the telephone or
online and the ability to access account values and transaction history in all
of the shareholder's direct accounts in the Pioneer Funds over the telephone or
online.

     Fourth, Pioneer Value Fund's lower operating expenses and Pioneer's
commitment until the second anniversary of the Reorganization to limit the
expenses (excluding extraordinary expenses) of the Investor Class of Pioneer
Value Fund to 1.10% of average daily net assets. The estimated expense ratio of
the Investor Class shares of Pioneer Value Fund is lower or equal to both the
gross expenses and expenses net of expense reimbursement of each class of shares
of your Safeco Fund. Although you will experience higher expenses once the
Investor Class shares convert to Class A shares after two years, the Class A
expense ratio for the most recent fiscal year was 1.19% of average daily net
assets, which was below the total gross and net expenses of the Class A shares
of your Safeco Fund.


     Fifth, the substantially larger size of Pioneer Value Fund offers greater
opportunity for diversification of the investment portfolio, which should help
to reduce risks.


     Sixth, shareholders who own shares in their name as of the closing of the
Reorganization (i.e., not in the name of a broker or other intermediary) and
maintain their account may purchase additional Class A shares of the
corresponding Pioneer Fund through such account in the future or may exchange
those shares for Class A shares of another Pioneer Fund or purchase Class A
share of another Pioneer Fund without paying any sales charge.

     Seventh, the Investor Class shares of Pioneer Value Fund received in the
Reorganization will provide Safeco Large-Cap Value Fund shareholders with
exposure to substantially the same investment product as they currently have.

     Pioneer and Symetra will pay all out of pocket expenses of the Safeco Funds
and the Pioneer Funds associated with the Reorganizations, including, but not
limited to: (1) the expenses associated with the preparation, printing and
mailing of any shareholder communications, including this joint Proxy
Statement/Prospectus, and any filings with the SEC and other governmental
authorities in connection with the Reorganizations; (2) the fees and expenses of
any proxy solicitation firm retained in connection with the Reorganizations; (3)
the legal fees and expenses incurred by the Safeco Funds in connection with the
Reorganizations; and (4) the Trustees' fees and out of pocket expenses incurred
as a result of the Reorganizations.

     The Trustees also considered that Pioneer and Symetra will benefit from the
Reorganization. See "Certain Agreements between Pioneer and Symetra."

     The Board of Trustees of Pioneer Value Fund also considered that the
Reorganization presents an excellent opportunity for the Pioneer Value Fund to
acquire investment assets without the obligation to pay commissions or other
transaction costs that a fund normally incurs when purchasing securities. This
opportunity provides an economic benefit to Pioneer Value Fund and its
shareholders.

     It is impossible to predict how many shares of Pioneer Value Fund will
actually be received and distributed by your Safeco Fund on the Reorganization
date. The table should not be relied upon to determine the amount of Pioneer
Value Fund's shares that will actually be received and distributed.


                     BOARD'S EVALUATION AND RECOMMENDATION


     For the reasons described above, the Trustees, including the Independent
Trustees, approved the Reorganization. In particular, the Trustees determined
that the Reorganization is in the best interests of your Safeco Fund. Similarly,
the Board of Trustees of Pioneer Value Fund, including its Independent Trustees,
approved the Reorganization. They also determined that the Reorganization is in
the best interests of Pioneer Value Fund.

     The Trustees recommend that the shareholders of your Safeco Fund vote FOR
the proposal to approve the Agreement and Plan of Reorganization.

                Approval of Agreement and Plan of Reorganization

                                     SUMMARY


     The following is a summary of more complete information appearing later in
this Proxy Statement/Prospectus or incorporated herein. You should read
carefully the entire proxy statement, including the form of Agreement and Plan
of Reorganization attached as EXHIBIT A-1 because they contain details that are
not in the summary.

     The Investor Class shares to be issued in the Reorganization will convert
to Class A shares after two years. Class A shares will have higher expenses per
share than Investor Class shares due to the Rule 12b-1 Plan. In addition,
although Pioneer has agreed to limit the expenses attributable to Investor Class
shares, Pioneer is not required to limit the expenses attributable to Class A
shares.

     In the table below, if a row extends across the entire table, the policy
disclosed applies to both your Safeco Fund and the Pioneer Fund.

Comparison of Principal Risks of Investing in the Funds


     Because each Fund has a similar investment objective, primary investment
policies and strategies, the Funds are subject to the same principal risks. Even
though each Fund seeks capital appreciation, you could lose money on your
investment or not make as much as if you invested elsewhere if:

     o    The stock market goes down (this risk may be greater in the short
          term)

     o    Mid-size or value stocks fall out of favor with investors

     o    The Fund's assets remain undervalued or do not have the potential
          value originally expected

     Each Fund also has risks associated with investing in mid-size companies.
Compared to large companies, mid-size companies, and the market for their equity
securities, are likely to:

     o    Be more sensitive to changes in earnings results and investor
          expectations

     o    Have more limited product lines and capital resources

     o    Experience sharper swings in market values

     o    Be harder to sell at the times and prices Pioneer thinks appropriate

     o    Offer greater potential for gain and loss


                                       96


     Investing in non-U.S. issuers may involve unique risks compared to
investing in securities of U.S. issuers. 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, Pioneer may not be able to sell the Fund's portfolio
          securities at times, in amounts and at prices it considers reasonable

     o    Adverse effect of currency exchange rates or controls on the value of
          the Fund's investments

     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 and social developments may adversely affect the
          securities markets

     o    Withholding and other non-U.S. taxes may decrease the Fund's return


     The Investor Class shares to be issued in the Reorganization will convert
to Class A shares after two years. Class A shares will have higher expenses per
share than Investor Class shares due to the Rule 12b-1 Plan. In addition,
although Pioneer has agreed to limit the expenses attributable to Investor Class
shares, Pioneer is not required to limit the expenses attributable to Class A
shares.


Past Performance


     Set forth below is performance information for each Fund. The bar charts
show how each Fund's total return (not including any deduction for sales
charges) has varied from year to year for each full calendar year. The tables
show average annual total return (before and after taxes) for each Fund over
time for each class of shares (including deductions for sales charges) compared
with a broad-based securities market index. The bar charts give an indication of
the risks of investing in each Fund, including the fact that you could incur a
loss and experience volatility of returns year to year. Past performance before
and after taxes does not indicate future results.

     Pioneer Mid Cap Value Fund's Investor Class shares will not be outstanding
prior to the closing of the Reorganization and consequently have no performance
history. However, the performance record of the Investor Class would be modestly
higher than the performance of Class A, B and C shares due to the lower expenses
applicable to the Investor Class.

is attached as Exhibit D.

(1)  No sales load will apply to shares received in the Reorganization by
     shareholders of your Safeco Fund who become shareholders of record of
     Pioneer Mid Cap Value Fund through the Reorganization. In addition,
     shareholders of your Safeco Fund who own shares in their own name (i.e.,
     not in the name of a broker or other intermediary) and maintain such
     account as of the closing of the Reorganization may purchase Class A Shares
     of Pioneer Mid Cap Value Fund or of any fund in the Pioneer family of funds
     through such account in the future without paying a sales charge.

     Multi-Cap Core Fund for certain Fund operating expenses (but not all of the
     operating expenses of the Fund) that exceeded the rate of 0.40% per annum
     of the Fund's average daily net assets. This arrangement included all Fund
     operating expenses except management fees, Rule 12b-1 fees, brokerage
     commissions, interest, and extraordinary expenses.

     the Reorganization, Pioneer will limit the expenses (excluding
     extraordinary expenses) of the Investor Class shares of Pioneer Mid Cap
     Value Fund to 1.10% of average daily net assets.


(4)  There is a higher charge for international wire redemptions, which may vary
     by country or dollar amount.


(5)  A low balance fee is charged once in year in December for accounts with
     balances under $1,000 in your Safeco Fund.

(6)  Purchases of $1,000,000 or more of Class A shares of your Safeco Fund are
     not subject to a front-end sales charge, but a 1.00% deferred sales charge
     will apply to redemptions made in the first twelve months except with
     respect to participant-directed redemptions from qualified retirement
     plans.

(7)  The contingent deferred sales charge on Class B shares of your Safeco Fund
     reduces to zero after six years from purchase, and the Class B shares
     convert to Class A shares at that time.


(8)  The contingent deferred sales charge on Class C shares applies only to
     redemptions made in the first twelve months after purchase.


(9)  The Investor Class shares to be issued in the Reorganization will convert
     to Class A shares after two years. Class A shares will have higher expenses
     per share than Investor Class shares due to the Rule 12b-1 Plan. In
     addition, although Pioneer has agreed to limit the expenses attributable to
     Investor Class shares, Pioneer is not required to limit the expenses
     attributable to Class A shares. Class A shares do not currently have an
     expense limitation.

     The hypothetical example below helps you compare the cost of investing in
each Fund. It assumes that: (a) you invest $10,000 in each Fund for the time
periods shown, (b) you reinvest all dividends and distributions, (c) your
investment has a 5% return each year, (d) each Fund's gross operating expenses
remain the same, (e) the expense limitations are in effect for five years for
Safeco Multi-Cap Core Fund and two years for Pioneer Mid Cap Value Fund and (f)
and the Investor Class shares of Pioneer Mid Cap Value Fund convert to Class A
shares after two years. The examples are for comparison purposes only and are
not a representation of either Fund's actual expenses or returns, either past or
future.

Reasons for the Proposed Reorganization


     The Trustees believe that the proposed Reorganization is in the best
interests of Safeco Multi-Cap Core Fund. The Trustees considered the following
matters, among others, in approving the proposal.

     First, SAM, the investment adviser to the Safeco Fund until August 2, 2004,
was acquired by Symetra. Symetra informed the Trustees that it did not intend to
continue to provide investment advisory services to the Safeco Funds.
Consequently, a change in your Safeco Fund's investment adviser was necessary.

     Second, the performance of Pioneer Mid Cap Value Fund is higher than the
historical investment performance of your Safeco Fund. For the one, five and ten
year periods ended June 30, 2004, Class A shares of Pioneer Mid Cap Value Fund
had an average annual return of 31.89%, 9.49% and 12.55%, respectively, compared
to an average annual return of the Class A shares and Investor Class shares of
18.34% and 25.78% (one year), 0.89% and 2.32% (five years), and 8.64% and 9.53%
(ten years), respectively, during the same periods. In addition, the Trustees
considered the track record of Pioneer in managing equity and fixed income
mutual funds.

     Third, the resources of Pioneer. At June 30, 2004, Pioneer managed over 62
investment companies and accounts with approximately $35 billion in assets.
Pioneer is part of the global asset management group of UniCredito Italiano
S.p.A., one of the largest banking groups in Italy, providing investment
management and financial services to mutual funds, institutions and other
clients. As of June 30, 2004, assets under management of UniCredito Italiano
S.p.A. were approximately $151 billion worldwide. Shareholders of your Safeco
Fund would become part of a significantly larger family of funds that offers a
more diverse array of investment options and enhanced shareholder account
options. The Pioneer family of mutual funds offers over 62 funds, including
domestic and international equity and fixed income funds and a money market fund
that will be available to your Safeco Fund's shareholders through exchanges. In
addition, Pioneer offers shareholders additional options for their accounts,
including the ability to transact and exchange shares over the telephone or
online and the ability to access account values and transaction history in all
of the shareholder's direct accounts in the Pioneer Funds over the telephone or
online.

     Fourth, Pioneer's commitment until the second anniversary of the
Reorganization to limit the expenses (excluding extraordinary expenses) of the
Investor Class of Pioneer Mid Cap Value Fund to 1.10% of average daily net
assets. The estimated expenses of the Investor Class shares of Pioneer Mid Cap
Value Fund are equal to or below both the gross expenses and expenses net of
expense reimbursement of each class of shares of your Safeco Fund. Although you
will experience higher expenses once the Investor Class shares convert to Class
A shares after two years, your expenses will remain the same until the second
anniversary of the Reorganization.

     Fifth, the substantially larger size of Pioneer Mid Cap Value Fund offers
greater opportunity for diversification of the investment portfolio, which
should help to reduce risks.

     Sixth, shareholders who own shares in their name as of the closing of the
Reorganization (i.e., not in the name of a broker or other intermediary) and
maintain their account may purchase additional Class A shares of the
corresponding Pioneer Fund through such account in the future or may exchange
those shares for Class A shares of another Pioneer Fund or purchase Class A
share of another Pioneer Fund without paying any sales charge.

     Seventh, the Investor Class shares of Pioneer Mid Cap Value Fund received
in the Reorganization will provide your Safeco Fund's shareholders with exposure
to substantially the same investment product as they currently have.

     Pioneer and Symetra will pay all out of pocket expenses of the Safeco Funds
and the Pioneer Funds associated with the Reorganizations, including, but not
limited to: (1) the expenses associated with the preparation, printing and
mailing of any shareholder communications, including this joint Proxy
Statement/Prospectus, and any filings with the SEC and other governmental
authorities in connection with the Reorganizations; (2) the fees and expenses of
any proxy solicitation firm retained in connection with the Reorganizations; (3)
the legal fees and expenses incurred by the Safeco Funds in connection with the
Reorganizations; and (4) the Trustees' fees and out of pocket expenses incurred
as a result of the Reorganizations.

     The Trustees also considered that Pioneer and Symetra will benefit from the
Reorganization. See "Certain Agreements between Pioneer and Symetra."

     The Board of Trustees of Pioneer Mid Cap Value Fund also considered that
the Reorganization presents an excellent opportunity for the Pioneer Mid Cap
Value Fund to acquire investment assets without the obligation to pay
commissions or other transaction costs that a fund normally incurs when
purchasing securities. This opportunity provides an economic benefit to Pioneer
Mid Cap Value Fund and its shareholders.

     It is impossible to predict how many shares of Pioneer Mid Cap Value Fund
will actually be received and distributed by your Safeco Fund on the
Reorganization date. The table should not be relied upon to determine the amount
of Pioneer Mid Cap Value Fund's shares that will actually be received and
distributed.


                      BOARD'S EVALUATION AND RECOMMENDATION


     For the reasons described above, the Trustees, including the Independent
Trustees, approved the Reorganization. In particular, the Trustees determined
that the Reorganization is in the best interests of your Safeco Fund. Similarly,
the board of trustees of Pioneer Mid Cap Value Fund, including its Independent
Trustees, approved the Reorganization. They also determined that the
Reorganization is in the best interests of Pioneer Mid Cap Value Fund.

     The Trustees recommend that the shareholders of your Safeco Fund vote FOR
the proposal to approve the Agreement and Plan of Reorganization.

                          Pioneer Small Cap Value Fund

                                  PROPOSAL 1(h)


                Approval of Agreement and Plan of Reorganization

                                     SUMMARY


     The following is a summary of more complete information appearing later in
this Proxy Statement/Prospectus or incorporated herein. You should read
carefully the entire proxy statement, including the form of Agreement and Plan
of Reorganization attached as EXHIBIT A-1 because they contain details that are
not in the summary.

     The Investor Class Shares to be issued in the Reorganization will convert
to Class A shares after two years. Class A shares will have higher expenses per
share than Investor Class shares due to the Rule 12b-1 Plan. In addition,
although Pioneer has agreed to limit the expenses attributable to Investor Class
shares, Pioneer is not required to limit the expenses attributable to Class A
shares.

     In the table below, if a row extends across the entire table, the policy
disclosed applies to both your Safeco Fund and the Pioneer Fund.

Comparison of Principal Risks of Investing in the Funds

     Because each Fund has a similar investment objective, primary investment
policies and strategies, the Funds are subject to the same principal risks. You
could lose money on your investment in either Fund or not make as much as if you
invested elsewhere if:

     o    The stock market goes down (this risk may be greater in the
          short-term)

     o    Small company or value stocks fall out of favor with investors

     o    The Fund's assets remain undervalued or do not have the potential
          value originally expected

     Each Fund also has risks associated with investing in small companies.
Compared to large companies, small companies, and the market for their equity
securities, are likely to:

     o    Be more sensitive to changes in the economy, earnings results and
          investor expectations

     o    Have more limited product lines and capital resources

     o    Experience sharper swings in market values


     o    Be harder to sell at the times and prices Pioneer thinks appropriate


     o    Offer greater potential for gain and loss

     Investments in the Funds are not bank deposits and are not insured or
guaranteed by the Federal Deposit Insurance Corporation or any other government
agency. You could lose money by investing in either Fund.


     The Investor Class shares to be issued in the Reorganization will convert
to Class A shares after two years. Class A shares will have higher expenses per
share than Investor Class shares due to the Rule 12b-1 Plan. In addition,
although Pioneer has agreed to limit the expenses attributable to Investor Class
shares, Pioneer is not required to limit the expenses attributable to Class A
shares.

     Pioneer Small Cap Value Fund's Investor Class shares will not be
outstanding prior to the closing of the Reorganization and consequently have no
performance history. However, the performance record of the Investor Class would
be modestly higher than the performance of Class A shares due to the lower
expenses applicable to the Investor Class.

- ----------

(1)  No sales load will apply to shares received in the Reorganization by
     shareholders of your Safeco Fund who become shareholders of record of
     Pioneer Small Cap Value Fund through the Reorganization. In addition,
     shareholders of your Safeco Fund who own shares in their own name (i.e.,
     not in the name of a broker or other intermediary) and maintain such
     account as of the closing of the Reorganization may purchase Class A Shares
     of Pioneer Small Cap Value Fund or of any fund in the Pioneer family of
     funds through such account in the future without paying a sales charge.

(2)  As described above, SAM had contractually agreed to reimburse Safeco
     Small-Cap Value Fund for certain Fund operating expenses (but not all of
     the operating expenses of the Fund) that exceeded the rate of 0.40% per
     annum of the Fund's average daily net assets. This arrangement included all
     fund operating expenses except management fees, Rule 12b-1 fees, brokerage
     commissions, interest, and extraordinary expenses.

(3)  Pioneer has agreed that through the second anniversary of the closing of
     the Reorganization, Pioneer will limit the expenses (excluding
     extraordinary expenses) of the Investor Class shares of Pioneer Small Cap
     Value Fund to 1.15% of average daily net assets.


(4)  There is a higher charge for international wire redemptions, which may vary
     by country or dollar amount.


(5)  A low balance fee is charged once each year in December for accounts with
     balances under $1,000 in your Safeco Fund.



                                      114



(6)  Purchases of $1,000,000 or more of Class A shares of your Safeco Fund are
     not subject to a front-end sales charge, but a 1.00% deferred sales charge
     will apply to redemptions made in the first twelve months except with
     respect to participant-directed redemptions from qualified retirement
     plans.

(7)  The contingent deferred sales charge on Class B shares of your Safeco Fund
     reduces to zero after six years from purchase, and the Class B shares
     convert to Class A shares at that time.


(8)  The contingent deferred sales charge on Class C shares applies only to
     redemptions made in the first twelve months after purchase.

(9)  The Investor Class shares to be issued in the Reorganization will convert
     to Class A shares after two years. Class A shares will have higher expenses
     per share than Investor Class shares due to the Rule 12b-1 Plan. In
     addition, although Pioneer has agreed to limit the expenses attributable to
     Investor Class shares, Pioneer is not required to limit the expenses
     attributable to Class A shares.


     The hypothetical example below helps you compare the cost of investing in
each Fund. It assumes that: (a) you invest $10,000 in each Fund for the time
periods shown, (b) you reinvest all dividends and distributions, (c) your
investment has a 5% return each year, (d) each Fund's gross operating expenses
remain the same, (e) the expense limitations are in effect for five years for
Safeco Small-Cap Value Fund and two years for Pioneer Small Cap Value Fund and
(f) and the Investor Class shares of Pioneer Small Cap Value Fund convert to
Class A shares after two years. The examples are for comparison purposes only
and are not a representation of either Fund's actual expenses or returns, either
past or future.

Reasons for the Proposed Reorganization


     The Trustees believe that the proposed Reorganization is in the best
interests of Safeco Small-Cap Value Fund. The Trustees considered the following
matters, among others, in approving the proposal.

     First, SAM, the investment adviser to the Safeco Fund until August 2, 2004,
was acquired by Symetra. Symetra informed the Trustees that it did not intend to
continue to provide investment advisory services to the Safeco Funds.
Consequently, a change in your Safeco Fund's investment adviser was necessary.

     Second, the long-term investment performance of Pioneer Small Cap Value
Fund is superior to your Safeco Fund's performance, although your Safeco Fund
had better performance during the most recent 12 month period. For the one and
five year periods ended June 30, 2004, Class A shares of Pioneer Small Cap Value
Fund had an average annual return of 31.83% and 13.77%, respectively, compared
to an average annual return of the Class A shares and Investor Class shares of
23.99% and 31.58% (one year) and 13.21% and 14.80% (five years), respectively,
during the same period. In addition, the Trustees considered the track record of
Pioneer in managing equity and fixed income mutual funds.

     Third, the resources of Pioneer. At June 30, 2004, Pioneer managed over 62
investment companies and accounts with approximately $35 billion in assets.
Pioneer is part of the global asset management group of UniCredito Italiano
S.p.A., one of the largest banking groups in Italy, providing investment
management and financial services to mutual funds, institutions and other
clients. As of June 30, 2004, assets under management of UniCredito Italiano
S.p.A. were approximately $151 billion worldwide. Shareholders of your Safeco
Fund would become part of a significantly larger family of funds that offers a
more diverse array of investment options and enhanced shareholder account
options. The Pioneer family of mutual funds offers over 62 funds, including
domestic and international equity and fixed income funds and a money market fund
that will be available to your Safeco Fund's shareholders through exchanges. In
addition, Pioneer offers shareholders additional options for their accounts,
including the ability to transact and exchange shares over the telephone or
online and the ability to access account values and transaction history in all
of the shareholder's direct accounts in the Pioneer Funds over the telephone or
online.

     Fourth, Pioneer's commitment until the second anniversary of the
Reorganization to limit the expenses (excluding extraordinary expenses) of the
Investor Class of Pioneer Small Cap Value Fund to 1.15% of average daily net
assets. This expense ratio is lower than both the gross expenses and expenses
net of expense reimbursement of the Class A, Class B and Class C shares of your
Safeco Fund and no higher than the gross and the same as the net expense of your
Safeco Fund's Investor Class shares. Although without the expense limitation
Pioneer Small Cap Value Fund's expenses are significantly higher than your
Safeco Fund's net expenses, the trustees believe that Pioneer Small Cap Value
Fund offers the potential for lower expenses through economies of scale.

     Fifth, the substantially larger size of Pioneer Small Cap Value Fund offers
greater opportunity for diversification of the investment portfolio, which
should help to reduce risks.

     Sixth, shareholders who own shares in their name as of the closing of the
Reorganization (i.e., not in the name of a broker or other intermediary) and
maintain their account may purchase additional Class A shares of the
corresponding Pioneer Fund through such account in the future or may exchange
those shares for Class A shares of another Pioneer Fund or purchase Class A
share of another Pioneer Fund without paying any sales charge.

     Seventh, the Investor Class shares of Pioneer Small Cap Value Fund received
in the Reorganization will provide Safeco Small-Cap Value Fund shareholders with
exposure to substantially the same investment product as they currently have.

     Pioneer and Symetra will pay all out of pocket expenses of the Safeco Funds
and the Pioneer Funds associated with the Reorganizations, including, but not
limited to: (1) the expenses associated with the preparation, printing and
mailing of any shareholder communications, including this joint Proxy
Statement/Prospectus, and any filings with the SEC and other governmental
authorities in connection with the Reorganizations; (2) the fees and expenses of
any proxy solicitation firm retained in connection with the Reorganizations; (3)
the legal fees and expenses incurred by the Safeco Funds in connection with the
Reorganizations; and (4) the Trustees' fees and out of pocket expenses incurred
as a result of the Reorganizations.

     The Trustees also considered that Pioneer and Symetra will benefit from the
Reorganization. See "Certain Agreements between Pioneer and Symetra."

     The Board of Trustees of Pioneer Small Cap Value Fund also considered that
the Reorganization presents an excellent opportunity for the Pioneer Small Cap
Value Fund to acquire investment assets without the obligation to pay
commissions or other transaction costs that a fund normally incurs when
purchasing securities. This opportunity provides an economic benefit to Pioneer
Small Cap Value Fund and its shareholders.

     It is impossible to predict how many shares of Pioneer Small Cap Value Fund
will actually be received and distributed by your Safeco Fund on the
Reorganization date. The table should not be relied upon to determine the amount
of Pioneer Small Cap Value Fund's shares that will actually be received and
distributed.


                      BOARD'S EVALUATION AND RECOMMENDATION


     For the reasons described above, the Trustees, including the Independent
Trustees, approved the Reorganization. In particular, the Trustees determined
that the Reorganization is in the best interests of your Safeco Fund. Similarly,
the Board of Trustees of Pioneer Small Cap Value Fund, including its Independent
Trustees, approved the Reorganization. They also determined that the
Reorganization is in the best interests of Pioneer Small Cap Value Fund.

     The Trustees recommend that the shareholders of your Safeco Fund vote FOR
the proposal to approve the Agreement and Plan of Reorganization.



                                      117


               TERMS OF EACH AGREEMENT AND PLAN OF REORGANIZATION

The Reorganizations


     o    Each Reorganization is scheduled to occur at 4:00 p.m., Eastern time,
          on December 10, 2004, unless your Safeco Fund and the corresponding
          Pioneer Fund agree in writing to a later date. Your Safeco Fund will
          transfer all of its assets to the corresponding Pioneer Fund. The
          corresponding Pioneer Fund will assume your Safeco Fund's liabilities
          that are included in the calculation of your Safeco Fund's net asset
          value on the Closing Date. The net asset value of both Funds will be
          computed as of 4:00 p.m., Eastern time, on the Closing Date.

     o    Each corresponding Pioneer Fund will issue to the corresponding Safeco
          Fund Investor Class shares with an aggregate net asset value equal to
          the net assets attributable to the corresponding Safeco Fund's shares.
          These shares will immediately be distributed to your Safeco Fund's
          shareholders in proportion to the relative net asset value of their
          holdings of your Safeco Fund's shares on the Closing Date. As a
          result, each Safeco Fund's shareholders will end up as Investor Class
          shareholders of the corresponding Pioneer Fund.


     o    After the distribution of shares, your Safeco Fund will be liquidated
          and dissolved.


     o    Each Reorganization is intended to result in no income, gain or loss
          being recognized for federal income tax purposes and will not take
          place unless both Funds receive a satisfactory opinion concerning the
          tax consequences of the Reorganization from Wilmer Cutler Pickering
          Hale and Dorr LLP, counsel to the Pioneer Funds.


Agreement and Plan of Reorganization


     The shareholders of each Safeco Fund are being asked to approve an
Agreement and Plan of Reorganization substantially in the form attached as
EXHIBIT A-1 or A-2 (each, a "Plan"). The description of the Plan contained
herein is qualified in its entirety by the attached copies, as appropriate.

     Conditions to Closing each Reorganization. The obligation of each Fund to
consummate each Reorganization is subject to the satisfaction of certain
conditions, including your Safeco Fund's performance of all of its obligations
under the Plan, the receipt of certain documents and financial statements from
your Safeco Fund and the receipt of all consents, orders and permits necessary
to consummate the Reorganization (see Sections 7 and 8 of the Plan).

     The obligations of both Funds are subject to the approval of the Plan by
the necessary vote of the outstanding shares of your Safeco Fund, in accordance
with the provisions of your Trust's trust instrument and by-laws. The Funds'
obligations are also subject to the receipt of a favorable opinion of Wilmer
Cutler Pickering Hale and Dorr LLP as to the federal income tax consequences of
each Reorganization (see Section 8.5 of the Plan).

     Termination of the Plan. The board of either the Safeco Trust or the
corresponding Pioneer Fund may terminate the Plan (even if the shareholders of
your Safeco Fund have already approved it) at any time before the Closing Date,
if that board believes in good faith that proceeding with the Reorganization
would no longer be in the best interests of shareholders.



                                      118



                        TAX STATUS OF EACH REORGANIZATION

     Each Reorganization is intended to result in no income, gain or loss being
recognized for United States federal income tax purposes and will not take place
unless both Funds involved in the Reorganization receive a satisfactory opinion
from Wilmer Cutler Pickering Hale and Dorr LLP, counsel to the Pioneer Funds,
substantially to the effect that each Reorganization will be a "reorganization"
within the meaning of Section 368(a) of the Code.


     As a result, for federal income tax purposes:


     o    No gain or loss will be recognized by your Safeco Fund upon (1) the
          transfer of all of its assets to the Pioneer Fund as described in this
          Proxy Statement/Prospectus or (2) the distribution by your Safeco Fund
          of Pioneer Fund shares to your Safeco Fund's shareholders;


     o    No gain or loss will be recognized by the Pioneer Fund upon the
          receipt of your Safeco Fund's assets solely in exchange for the
          issuance of Pioneer Fund shares to your Safeco Fund and the assumption
          of your Safeco Fund's liabilities by the corresponding Pioneer Fund;

     o    The basis of the assets of your Safeco Fund acquired by the
          corresponding Pioneer Fund will be the same as the basis of those
          assets in the hands of your Safeco Fund immediately before the
          transfer;

     o    The tax holding period of the assets of your Safeco Fund in the hands
          of the corresponding Pioneer Fund will include your Safeco Fund's tax
          holding period for those assets;

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


     o    The basis of the Pioneer Fund shares received by you in the
          Reorganization will be the same as the basis of your shares of your
          Safeco Fund surrendered in exchange; and


     o    The tax holding period of the Pioneer Fund shares you receive will
          include the tax holding period of the shares of your Safeco Fund
          surrendered in the exchange, provided that you held the shares of your
          Safeco Fund as capital assets on the date of the exchange.


     In rendering such opinions, counsel shall rely upon, among other things,
reasonable assumptions as well as representations of your Safeco Fund and the
Pioneer Fund (see the annexes to the Plan).


     No tax ruling has been or will be received from the Internal Revenue
Service ("IRS") in connection with the Reorganizations. 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.


     You should consult your tax adviser for the particular tax consequences to
you of the Reorganization, including the applicability of any state, local or
foreign tax laws.



                                      119



                               PROPOSALS 2(a)-(h)

         APPROVAL OF INTERIM INVESTMENT ADVISORY AGREEMENT WITH PIONEER


Background


     Having determined to recommend the Reorganizations, the Trustees appointed
Pioneer as investment adviser to each Fund commencing August 2, 2004, until the
closing of the Reorganizations given that Symetra had indicated that it did not
wish to continue to offer investment advisory services to the Safeco Funds. If
both the Reorganization and appointment of Pioneer are approved, the interim
investment advisory agreement will continue in effect until the closing of the
Reorganization. In connection with the retention of Pioneer, the sub-advisory
agreement with Bank of Ireland Asset Management (U.S.) Limited with respect to
Safeco International Stock Fund, and the sub-advisory agreement with RCM Capital
Management LLC with respect to Safeco Large-Cap Growth Fund, were terminated.

Interim Investment Advisory Agreement

     Under the Investment Company Act, shareholders must approve any new
investment advisory agreement for the Funds. However, Rule 15a-4 under the
Investment Company Act permits your Trustees to appoint an adviser on an interim
basis without prior shareholder approval if the new adviser agrees to provide
such services on the same terms as the previous adviser and approves the
investment advisory agreement with that adviser. An adviser may manage on such
an interim basis for a period of 150-days. Because Pioneer will be making the
payment to Symetra discussed under "Background to the Reorganizations," any fees
that Pioneer would be entitled to under the interim investment advisory
agreement will be held in escrow by the Fund until shareholder approval of the
agreement is obtained. If shareholders of a Safeco Fund do not approve the
interim advisory agreement, Pioneer will not receive the fee under the current
investment advisory agreement with SAM but instead would be paid a fee based
upon Pioneer's cost in managing the Fund. During this period prior to the
meeting, the Fund will be managed as separate Funds and will not be combined
with a Pioneer Fund. During this period, you also will not be able to exchange
your shares in a Fund for shares of a Pioneer Fund. If the appointment of
Pioneer as interim investment adviser is not approved by December 30, 2004,
Pioneer will no longer provide advisory services to the Funds, unless an
extension of the 150 day period is permitted by a rule or independent position
of the staff of the SEC. Reasons for Approving the Interim Investment Advisory
Agreement and Board's Recommendation

Reasons for Approving the Interim Investment Advisory Agreement and Board's
Recommendation

     The Trustees recommend that the shareholders of the Safeco Funds approve
the interim investment advisory agreements. In determining to appoint Pioneer as
investment advisor on an interim basis, the Trustees considered many of the same
factors on which the recommendation to approve the Reorganizations are based.
These factors include:

     o    SAM, the investment adviser to the Safeco Funds until August 2, 2004,
          was acquired by Symetra. Symetra informed the Trustees that it was not
          interested in continuing to provide investment advisory services to
          the Safeco Funds. Consequently, a change in your Fund's investment
          adviser was necessary.

     o    The resources of Pioneer. At June 30, 2004, Pioneer managed over 62
          investment companies and accounts with approximately $35 billion in
          assets. Pioneer is part of the global asset management group of
          UniCredito Italiano S.p.A., one of the largest banking groups in
          Italy, providing investment management and financial services to
          mutual funds, institutions, and other clients. As of June 30, 2004,
          assets under management of UniCredito Italiano S.p.A. were
          approximately $151 billion worldwide.

     o    The track record of Pioneer in managing other investment companies
          with similar strategies.

     o    Pioneer's willingness to proceed with the Reorganizations and to limit
          expenses of the Fund as discussed above.

     o    Pioneer's investment process, style and philosophy with respect to
          equity and fixed income investing.

     o    The expertise of John Carey as portfolio manager of Pioneer Fund and
          the head of equity investments at Pioneer.

     o    Pioneer's willingness to act as investment adviser to each of the
          Funds.


Safeco Advisory Agreement


     The following is a summary of the material terms of the Safeco Advisory
Agreement. The Safeco Advisory Agreement terminated on August 2, 2004.

     Services. Under the terms of the Safeco Advisory Agreement, SAM managed the
Funds' investments, subject to the supervision of the Board. At its expense, SAM
provided office space and all necessary office facilities, equipment and
personnel for managing the investments of the Funds.



                                      120



     Compensation. As compensation under the Safeco Advisory Agreement, each
Safeco Fund paid SAM a monthly advisory fee at an annual rate as listed in the
below table of the Fund's average daily net assets calculated each business day
and paid monthly, as listed in the table below. In addition, SAM had
contractually agreed to reimburse each Fund to the extent a Fund's total annual
expenses during any of the Fund's fiscal years, exceed 0.40% of its average
daily net asset value in such year. This arrangement included all Fund operating
expenses except management fees, Rule 12b-1 fees, brokerage commissions,
interest, and extraordinary expenses.

     In addition to the management fee, your Safeco Fund paid SAM, in its
capacity as administrator and fund accounting agent an administrative services
fee of 0.05% of your Safeco Fund's average daily net assets up to the first
$200,000,000 and 0.01% of its net assets thereafter, and an accounting fee of
0.04% of the Fund's average daily net assets up to the first $200,000,000 and
0.01% of its net assets thereafter.

     Limitation of Liability. The Safeco Advisory Agreement provided that SAM
shall not be subject to liability to the Funds or to any shareholder of the
Funds for any loss suffered by a Fund or its shareholders from or as a
consequence of any act or omission of SAM, or of any of the partners, employees
or agents of SAM in connection with or pursuant to the Agreement, except by
reason of willful misfeasance, bad faith or gross negligence on the part of SAM
in the performance of its duties or by reason of reckless disregard by SAM of
its obligations and duties under the Agreement.

                         VOTING RIGHTS AND REQUIRED VOTE

     Each share of your Safeco Fund is entitled to one vote and each fractional
share shall be entitled to a proportionate fractional vote. A quorum is required
to conduct business at the Meeting. With respect to each Safeco Fund, the
presence in person or by proxy of one-third of the outstanding shares of a
Safeco Fund entitled to cast votes at the Meeting will constitute a quorum with
respect to that Safeco Fund. A favorable vote of a "majority of the outstanding
voting securities" of the applicable Fund is required to approve each Proposal.
Under the Investment Company Act, the vote of a majority of the outstanding
voting securities means the affirmative vote of the lesser of (i) 67% or more of
the shares of the applicable Safeco Fund represented at the meeting, if at least
50% of all outstanding shares of the Safeco Fund are represented at the meeting,
or (ii) 50% or more of the outstanding shares of the Safeco Fund entitled to
vote at the meeting.

                 ADDITIONAL INFORMATION ABOUT THE PIONEER FUNDS

Investment Adviser


     Pioneer serves as the investment adviser to each Pioneer Fund. Pioneer is
an indirect, wholly owned subsidiary of UniCredito Italiano S.p.A., one of the
largest banking groups in Italy. Pioneer is part of the global asset management
group providing investment management and financial services to mutual funds,
institutions and other clients. As of June 30, 2004, assets under management
were approximately $150 billion worldwide, including over $35 billion in assets
under management by Pioneer. Pioneer's main office is at 60 State Street,
Boston, Massachusetts 02109. Pioneer's U.S. mutual fund investment history
includes creating one of the first mutual funds in 1928.



                                      122



     The Board of Trustees of the Pioneer Funds is responsible for overseeing
the performance of each of Pioneer Fund's investment adviser and subadviser, if
any, and determining whether to approve and renew the fund's investment advisory
agreement and the subadvisory agreements.


     Pioneer has received an order (the "Exemptive Order") from the SEC that
permits Pioneer, subject to the approval of the Pioneer Funds' board of
trustees, to hire and terminate a subadviser or to materially modify an existing
subadvisory agreement for a Pioneer Fund without shareholder approval. Pioneer
retains the ultimate responsibility to oversee and recommend the hiring,
termination and replacement of any subadviser. To the extent that the SEC adopts
a rule that would supersede the Exemptive Order, Pioneer and the Pioneer Funds
intend to rely on such rule to permit Pioneer, subject to the approval of the
Pioneer Funds' board of trustees and any other applicable conditions of the
rule, to hire and terminate a subadviser or to materially modify an existing
subadvisory agreement for a Pioneer Fund without shareholder approval.

Buying, Exchanging and Selling Shares of the Pioneer Funds


     Net Asset Value. Each Pioneer Fund's net asset value is the value of its
portfolio of securities plus any other assets minus its operating expenses and
any other liabilities. Each Pioneer Fund calculates a net asset value for each
class of shares every day the New York Stock Exchange is open when regular
trading closes (normally 4:00 p.m. Eastern time).


     Each Pioneer Fund generally values its portfolio securities using closing
market prices or readily available market quotations. When closing market prices
or market quotations are not available or are considered by Pioneer to be
unreliable, a Pioneer Fund may use a security's fair value. Fair value is the
valuation of a security determined on the basis of factors other than market
value in accordance with procedures approved by the Pioneer Funds' trustees.
Each Pioneer Fund also may use the fair value of a security, including a
non-U.S. security, when Pioneer determines that the closing market price on the
primary exchange where the security is traded no longer accurately reflects the
value of the security due to factors affecting one or more relevant securities
markets or the specific issuer. The use of fair value pricing by a Pioneer Fund
may cause the net asset value of its shares to differ from the net asset value
that would be calculated using closing market prices. International securities
markets may be open on days when the U.S. markets are closed. For this reason,
the value of any international securities owned by a Pioneer Fund could change
on a day you cannot buy or sell shares of the fund. Each Pioneer Fund may use a
pricing service or a pricing matrix to value some of its assets. Debt securities
with remaining maturities of 60 days or less are valued at amortized cost, which
is a method of determining a security's fair value.


     The Pioneer International Equity Fund primarily invests in securities of
non-U.S. issuers and the markets for these securities generally close prior to
the time the Fund determines its net asset value. However, the value of these
securities continues to be influenced by changes in the global markets.
Consequently, the trustees have determined to use the fair value of these
securities as of the time the fund determines its net asset value, based upon
data from a pricing service. On a daily basis, the pricing service recommends
changes, based upon a proprietary model, to the closing market prices of each
non-U.S. security held by the fund to reflect the security's fair value at the
time the fund determines its net asset value. The fund applies these
recommendations in accordance with procedures approved by the trustees. A
security's fair value determined in this manner may differ from the security's
closing market price on the date the fund determines its net asset value or the
opening price of the security on the next business day. The fund's use of this
method may significantly affect its net asset value compared to the net asset
value that would have been determined using closing market prices. The fund also
may take other factors influencing specific markets or issuers into
consideration in determining the fair value of a non-U.S. security.

     You buy or sell shares at the share price. When you buy Class A shares, you
pay an initial sales charge unless you qualify for a waiver or reduced sales
charge. The Class A shares of the Pioneer Funds you receive in the
Reorganizations will not be subject to any sales charge. Moreover, if you own
shares in your own name as of the closing of the Reorganizations (i.e., not in
the name of a broker or other intermediary) and maintain your account, you may
purchase additional Class A shares of the corresponding Pioneer Fund through
such account in the future or may exchange those shares for Class A shares of
another Pioneer Fund without paying any sales charge.


     Opening Your Account. If your shares are held in your investment firm's
name, the options and services available to you may be different from those
described herein or in the Pioneer Fund's prospectus. Ask your investment
professional for more information.

     If you invest in a Pioneer Fund through investment professionals or other
financial intermediaries, including wrap programs and fund supermarkets,
additional conditions may apply to your investment in a Pioneer Fund, and the
investment professional or intermediary may charge you a transaction-based 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.

     Account Options. Use your account application to select options and
privileges for your account. You can change your selections at any time by
sending a completed account options form to the transfer agent. You may be
required to obtain a signature guarantee to make certain changes to an existing
account.

     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 transfer
agent.

     When you request a telephone transaction the transfer agent will try to
confirm that the request is genuine. The transfer agent records the call,
requires the caller to provide the personal identification number 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.


     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 Pioneer Fund shares online.



     To establish online transaction privileges complete an account options
form, write to the transfer agent or complete the online authorization screen
on: www.pioneerfunds.com.

     To use online transactions, you must read and agree to the terms of an
online transaction agreement available on the Pioneer website. When you or your
investment firm requests an online transaction the transfer agent electronically
records the transaction, requires an authorizing password and sends a written
confirmation. The Pioneer Funds 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.

     Share Price. If you place an order with your investment firm before the New
York Stock Exchange closes and your investment firm submits the order to PFD
prior to PFD's close of business (usually 5:30 p.m. Eastern time), your share
price will be calculated that day. Otherwise, your price per share will be
calculated at the close of the New York Stock Exchange after the distributor
receives your order. Your investment firm is responsible for submitting your
order to the distributor.

     Buying Pioneer Fund Shares. You may buy shares of each Pioneer Fund from
any investment firm that has a sales agreement with PFD. If you do not have an
investment firm, please call 1-800-225-6292 for information on how to locate an
investment professional in your area.

     You can buy shares of the Pioneer Funds at the offering price. The
distributor may reject any order until it has confirmed the order in writing and
received payment. The fund reserves the right to stop offering any class of
shares.


     Minimum Investment Amounts. Your initial investment must be at least
$1,000. Additional investments must be at least $100 for Class A 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 minimum investment amount does not
apply for purposes of the Reorganization.


     Exchanging Pioneer Fund Shares. You may exchange your shares in a Pioneer
Fund for shares of the same class of another Pioneer mutual fund. Your exchange
request must be for at least $1,000 unless the fund you are exchanging into has
a different minimum. 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 policy as described in each fund's prospectus.

     Selling Pioneer Fund Shares. Your shares will be sold at net asset value
per share next calculated after the Pioneer Fund, or authorized agent, and as a
broker-dealer, receives your request in good order. 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. Normally you will be paid within
seven days. 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 may have to pay federal income taxes on a sale or an exchange.

                                Selling Shares
  
     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 PFD to act as its agent in the repurchase of

     Exchange Privilege

     You may make up to four exchange redemptions of $25,000 or
     more per account per calendar year.

     Excessive Trading

     The fund discourages excessive and/or trading practices, such as
     market timing, that may disrupt portfolio management strategies
     and harm fund request until it is received in performance. These
     practices consist of:
     o Selling shares purchased within the preceding 90 days;
     o Two or more purchases and redemptions in any 90-day period;
       or
     o Any other series of transactions indicative of a timing pattern

     If we identify an account that engages in such activity, the fund
     and the distributor reserve the right to refuse or restrict any
     purchase order (including exchanges) for that account and other
     accounts under common ownership or control.



Pioneer Fund Shareholder Account Policies

     Signature Guarantees and Other Requirements. You are required to obtain a
signature guarantee when you are:

     o    Requesting certain types of exchanges or sales of Pioneer Fund shares

     o    Redeeming shares for which you hold a share certificate

     o    Requesting certain types of changes for your existing account


     You can obtain a signature guarantee from most broker-dealers, banks,
credit unions (if authorized under state law) and federal savings and loan
associations. You cannot obtain a signature guarantee from a notary public. All
Pioneer Funds will 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. Fiduciaries and corporations are required to submit additional
documents to sell Pioneer Fund shares.


     Exchange Limitation. You may only make up to four exchange redemptions of
$25,000 or more per account per calendar year out of a fund. Each fund's
exchange limitation is intended to discourage short-term trading in fund shares.
Short-term trading can increase the expenses incurred by the fund and make
portfolio management less efficient. In determining whether the exchange
redemption limit has been reached, Pioneer may aggregate a series of exchanges
(each valued at less than $25,000) and/or fund accounts that appear to be under
common ownership or control. Pioneer may view accounts for which one person
gives instructions or accounts that act on advice provided by a single source to
be under common control.


     The exchange limitation does not apply to automatic exchange transactions
or to exchanges made by participants in employer-sponsored retirement plans
qualified under Section 401(a) of the IRC. While financial intermediaries that
maintain omnibus accounts that



                                      126


invest in the fund are requested to apply the exchange limitation policy to
shareholders who hold shares through such accounts, we do not impose the
exchange limitation policy at the level of the omnibus account and are not able
to monitor compliance by the financial intermediary with this policy.

     Redemption Fee. Pioneer International Equity Fund has adopted a redemption
fee on short term holdings of the fund's shares. If you sell or exchange shares
within 30 days of any purchase of fund shares, the fund will apply a 2% fee to
the entire amount of your sales proceeds. The fund's redemption fee is intended
to discourage short-term trading in fund shares. Short-term trading can increase
the expenses incurred by the fund and make portfolio management less efficient.

     Excessive Trading. The fund discourages excessive and short-term trading
practices, such as market timing, that may disrupt portfolio management
strategies and harm fund performance. Although there is no generally applied
standard in the marketplace as to what level of trading activity is excessive,
we may consider trading in the fund's shares to be excessive 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 is indicative of a timing
          pattern or strategy; or

     o    We reasonably believe that you have engaged in such practices in
          connection with other mutual funds.

     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 has engaged in excessive short-term trading that we believe may be
harmful to the fund, we will ask the investor or broker to cease such activity
and we will refuse to process purchase orders (including purchases by exchange)
of such investor, broker or accounts that we believe are under their control. In
determining whether to take such actions, we seek to act in a manner that is
consistent with the best interests of the fund's shareholders. We also limit the
number of exchanges of $25,000 or more in any calendar year.

     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. Frequently, fund
shares 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, are
aggregated. Our ability to monitor trading practices by investors purchasing
shares through omnibus accounts is limited and dependent upon the cooperation of
the financial intermediary in observing the fund's policies.

     Minimum Account Size. Each Pioneer Fund requires that you maintain a
minimum account value of $500. If you hold less than the minimum in your account
because you have sold or exchanged some of your shares, the Pioneer Fund will
notify you of its intent to sell your shares and close your account. You may
avoid this by increasing the value of your account to at least the minimum
within six months of the notice from the fund.

     Telephone Access. You may have difficulty contacting the Pioneer Fund by
telephone during times of market volatility or disruption in telephone service.
If you are unable to reach the Pioneer Fund by telephone, you should communicate
with the fund in writing.


     Share Certificates. Normally, your shares will remain on deposit with the
transfer agent and certificates will not be issued. If you are legally required
to obtain a certificate, you may request one for your Class A shares only. A fee
may be charged for this service. Any share certificates of the Safeco Funds
outstanding at the Closing of the Reorganization will be deemed to be cancelled
and will no longer represent shares of the Funds.

     Other Policies. Each Pioneer Fund may suspend transactions in shares when
trading on the New York Stock Exchange is closed or restricted, when an
emergency exists that makes it impracticable, as determined by the SEC, for the
fund to sell or value its portfolio securities or with the permission of the
SEC.


     Each Pioneer Fund or PFD may revise, suspend or terminate the account
options and services available to shareholders at any time.

     Each Pioneer Fund reserves the right to redeem in kind by delivering
portfolio securities to a redeeming shareholder, provided that the Pioneer Fund
must pay redemptions in cash if a shareholder's aggregate redemptions in a 90
day period are less than $250,000 or 1% of the fund's net assets.


Dividends and Capital Gains


     Each Pioneer Fund generally pays any distributions of net short- and
long-term capital gains and dividends from any net investment income at least
annually.


                                      127


     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 close to the time that the fund makes a
distribution, generally you will pay a higher price per share and you will pay
taxes on the amount of the distribution whether you reinvest the distribution or
receive it as cash.

Taxes


     For U.S. federal income tax purposes, distributions from each Pioneer
Fund's net long-term capital gains (if any) are considered long-term capital
gains and may be taxable to you at different maximum rates depending upon their
source and other factors. Short-term capital gain distributions for each Pioneer
Fund are taxable as ordinary income.

     Dividends from net investment income are taxable either as ordinary income
or, if so designated by the fund and certain other conditions, including holding
period requirements, are met by the fund and the shareholder, as "qualified
dividend income" taxable to individual shareholders at the maximum 15% U.S.
federal tax rate. Dividends and distributions generally are taxable, whether you
take payment in cash or reinvest them to buy additional Pioneer Fund shares.


     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. In January of each year each Pioneer Fund will mail to you
information about your dividends, distributions and any shares you sold in the
previous calendar year.

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


     You should ask your tax adviser about any federal, state and foreign tax
considerations, including possible additional withholding taxes for non-U.S.
shareholders. You may also consult the "Tax Status" section of each Pioneer
Fund's statement of additional information for a more detailed discussion of
U.S. federal income tax considerations, including qualified dividend income
considerations that may affect the Pioneer Fund and its shareholders.

     Pioneer Funds' Class A Rule 12b-1 Plans. As described above, each Pioneer
Fund has adopted a Rule 12b-1 plan for its Class A shares (the "Class A Plans"
or the "Plans"). Because the 12b-1 fees payable under each Plan are an ongoing
expense, over time they may increase the cost of your investment and your shares
may cost more than shares that are not subject to a distribution or service fee
or sales charge.

     Compensation and Services. Each Class A Plan is a reimbursement plan, and
distribution expenses of PFD are expected to substantially exceed the
distribution fees paid by the fund in a given year. Pursuant to each Class A
Plan the fund reimburses PFD for its actual expenditures to finance any activity
primarily intended to result in the sale of Class A shares or to provide
services to holders of Class A shares, provided the categories of expenses for
which reimbursement is made are approved by the board of trustees. The expenses
of the fund pursuant to the Class A Plan are accrued daily at a rate which may
not exceed the annual rate of 0.25% of the fund's average daily net assets
attributable to Class A shares.

     Trustee Approval and Oversight. Each Plan was last approved by the board of
trustees of each Pioneer Fund, including a majority of the independent trustees,
by votes cast in person at meetings called for the purpose of voting on the Plan
on December 6, 2003. Pursuant to the Plan, at least quarterly, PFD will provide
each fund with a written report of the amounts expended under the Plan and the
purpose for which these expenditures were made. The trustees review these
reports on a quarterly basis to determine their continued appropriateness.

     Term, Termination and Amendment. Each Plan's adoption, terms, continuance
and termination are governed by Rule 12b-1 under the Investment Company Act. The
board of trustees believes that there is a reasonable likelihood that the Plans
will benefit each fund and its current and future shareholders. The Plans may
not be amended to increase materially the annual percentage limitation of
average net assets which may be spent for the services described therein without
approval of the shareholders of the fund affected thereby, and material
amendments of the Plans must also be approved by the trustees as provided in
Rule 12b-1.

FINANCIAL HIGHLIGHTS


     The following tables show the financial performance of each Pioneer Fund
for the past five fiscal years and, if applicable, for any recent semiannual
period (or the period during which each Pioneer Fund has been in operation, if
less than five years). Certain information reflects financial results for a
single Pioneer Fund share. "Total return" shows how much an investment in a
Pioneer Fund would have increased or decreased during each period, assuming you
had reinvested all dividends and other distributions. In the case of each
Pioneer Fund, each fiscal year ended on or after the fiscal year ended June 30,
2002 has been audited by Ernst & Young LLP, each Pioneer Fund's independent
registered public accounting firm, as stated in their reports incorporated by
reference in this registration statement. For fiscal years prior to the fiscal
year ended June 30, 2002, the financial statements of each Pioneer Fund were
audited by Arthur Anderson LLP. The information for any semiannual period has
not been audited.

(a)  At January 1, 2001, the Fund began accreting discounts and amortizing
     premiums on debt securities. The effect of this change for the year ended
     December 31, 2001 was to decrease net investment income by less than one
     cent per share, increase net realized and unrealized gain (loss) by less
     than one cent per share and decrease the ratio of net investment income to
     average net assets assuming reduction for fees paid indirectly from 2.02%
     to 1.98%. Per share ratios and supplemental data for periods prior to
     January 1, 2002, have not been restated to reflect this change in
     presentation.

                       INFORMATION CONCERNING THE MEETING


Solicitation of Proxies


     In addition to the mailing of these proxy materials, proxies may be
solicited by telephone, by fax or in person by the trustees and officers of your
Safeco Fund or its affiliates, including personnel of your Safeco Fund's
transfer agent, Pioneer Funds' investment adviser, Pioneer, Pioneer Funds'
transfer agent, PIMSS, or by broker-dealer firms. Georgeson Shareholder
Communications Corporation, 17 State Street, New York, NY 10004, has been
retained to provide proxy solicitation services to the Funds at a cost of
approximately $30,000. Pioneer and Symetra will bear the cost of such
solicitation.


Revoking Proxies

     A Safeco Fund shareholder signing and returning a proxy has the power to
revoke it at any time before it is exercised:


     o    by filing a written notice of revocation with your Safeco Fund's
          transfer agent, Safeco Services Corporation, at 4854 154th Place,
          N.E., Redmond, WA 98052, or


     o    by returning a duly executed proxy with a later date before the time
          of the Meeting, or

     o    if a shareholder has executed a proxy but is present at the Meeting
          and wishes to vote in person, by notifying the secretary of your
          Safeco Fund (without complying with any formalities) at any time
          before it is voted.

     Being present at the Meeting alone does NOT revoke a previously executed
and returned proxy.

Outstanding Shares and Quorum


     Only shareholders of record on October 8, 2004 (the "record date") are
entitled to notice of and to vote at the Meetings. As of the record date, the
following number of shares of each Safeco Fund were outstanding.

  Safeco Small-Cap Value Fund ..............        3,908,412.105



Other Business


     Your Safeco Fund's board of trustees knows of no business to be presented
for consideration at the Meetings other than Proposals 1(a)-(h) and 2(a)-(h). If
other business is properly brought before a Meeting, proxies will be voted
according to the best judgment of the persons named as proxies.


Adjournments

     If, by the time scheduled for a Meeting, a quorum of shareholders of a Fund
is not present or if a quorum is present but sufficient votes "for" the
proposals have not been received, the persons named as proxies may propose the
Meeting with respect to one or more of the Funds to another date and time, and
the Meeting may be held as adjourned within a reasonable time after the date set
for the original Meeting for that Fund without further notice. Any such
adjournment will require the affirmative vote of a majority of the votes cast on
the question in person or by proxy at the session of the Meeting to be
adjourned. The persons named as proxies will vote all proxies in favor of the
adjournment that voted in favor of the proposal or that abstained. They will
vote against such adjournment those proxies required to be voted against the
proposal. Broker non-votes will be disregarded in the vote for adjournment. If
the adjournment requires setting a new record date or the adjournment is for
more than 120 days of the original Meeting (in which case the board of trustees
of your Safeco Fund will set a new record date), your Safeco Fund will give
notice of the adjourned meeting to its shareholders.


                                      136


Telephone Voting


     In addition to soliciting proxies by mail, by fax or in person, your Safeco
Fund may also arrange to have votes recorded by telephone by officers and
employees of your Safeco Fund or by personnel of the adviser or transfer agent
or a third party solicitation firm. The telephone voting procedure is designed
to verify a shareholder's identity, to allow a shareholder to authorize the
voting of shares in accordance with the shareholder's instructions and to
confirm that the voting instructions have been properly recorded. If these
procedures were subject to a successful legal challenge, these telephone votes
would not be counted at the Meeting. Your Safeco Fund has not obtained an
opinion of counsel about telephone voting, but is currently not aware of any
challenge.


     o    A shareholder will be called on a recorded line at the telephone
          number in the Fund's account records and will be asked to provide the
          shareholder's social security number or other identifying information.

     o    The shareholder will then be given an opportunity to authorize proxies
          to vote his or her shares at the Meeting in accordance with the
          shareholder's instructions.

     o    To ensure that the shareholder's instructions have been recorded
          correctly, the shareholder will also receive a confirmation of the
          voting instructions by mail.

     o    A toll-free number will be available in case the voting information
          contained in the confirmation is incorrect.

     o    If the shareholder decides after voting by telephone to attend the
          Meeting, the shareholder can revoke the proxy at that time and vote
          the shares at the Meeting.

Internet Voting

     You will also have the opportunity to submit your voting instructions via
the Internet by utilizing a program provided through a vendor. Voting via the
Internet will not affect your right to vote in person if you decide to attend
the Meeting. Do not mail the proxy card if you are voting via the Internet. To
vote via the Internet, you will need the "control number" that appears on your
proxy card. These Internet voting procedures are designed to authenticate
shareholder identities, to allow shareholders give their voting instructions,
and to confirm that shareholders instructions have been recorded properly. If
you are voting via the Internet you should understand that there may be costs
associated with electronic access, such as usage charges from Internet access
providers and telephone companies, that must be borne by you.

     o    Read the proxy statement and have your proxy card at hand.

     o    Go to the Web site listed on your proxy card.

     o    Enter control number found on your proxy card.

     o    Follow the simple instructions on the Web site. Please call [        ]
          us at [1-800         ] if you have any problems.

     o    To insure that your instructions have been recorded correctly you will
          receive a confirmation of your voting instructions immediately after
          your submission and also by e-mail if chosen.

Shareholders' Proposals


     Your Safeco Fund is not required, and does not intend, to hold meetings of
shareholders each year. Instead, meetings will be held only when and if
required. Any shareholders desiring to present a proposal for consideration at
the next meeting for shareholders must submit the proposal in writing, so that
it is received by the your Safeco Fund to Safeco Mutual Funds, Attention: Legal
Department at 4854 154th Place N.E., Redmond, WA 98052 within a reasonable time
before any meeting. If the Reorganization is completed, your Safeco Fund will
not hold another shareholder meeting.


Appraisal Rights


     If the Reorganization of your Safeco Fund is approved at the Meeting,
shareholders of your Safeco Fund will not have the right to dissent and obtain
payment of the fair value of their shares because the exercise of appraisal
rights is subject to the forward pricing requirements of Rule 22c-1 under the
Investment Company Act, which supersede state law. Shareholders of your Safeco
Funds, however, have the right to redeem their Fund shares until the closing
date of the Reorganizations. After the Reorganization, shareholders of your
Safeco Fund will hold shares of a Pioneer Fund which may also be redeemed at net
asset value without being subject to any deferred sales charges.

                 Exhibit B -- Form of Interim Advisory Agreement


     AGREEMENT dated as of August 2, 2004, between Pioneer Investment
Management, Inc. ("Pioneer"), a Delaware corporation and a member of the
UniCreditio Italiano Banking Group, Register of Banking Groups, and [SAFECO
TRUST], a Delaware statutory trust (the "Trust"), on behalf of its series
[SAFECO FUNDS] (the "Fund").


     Whereas, Safeco Asset Management Company has acted as investment adviser to
the Fund pursuant to an Investment Advisory Agreement dated (the "Prior
Agreement").


     Whereas, the Prior Agreement has been approved by the Board of Trustees of
the Trust and the shareholders of the Fund.

     Whereas, the Prior Agreement is being terminated as a result of assignment.

     Whereas, the Board of Trustees has determined to appoint Pioneer as
investment adviser to the Fund.

     Whereas, this Agreement is being entered into in reliance upon Rule 15a-4
under the Investment Company Act of 1940, as amended (the "Investment Company
Act").

     Now therefore the Trust and Pioneer agree as follow:

     Section 1. The Trust appoints Pioneer as investment adviser of the Funds
for the period and on the terms set forth herein. Pioneer accepts such
appointment.

     Section 2. Pioneer and the Trust, on behalf of the Fund, hereby agree that
the provisions of the Prior Agreement (other than as to the term of the Prior
Agreement, the identity of the Adviser and the use of the "Safeco" name) are
incorporated herein by reference and made a part hereof as if references to the
Adviser were to Pioneer. Without limiting the forgoing, Pioneer shall be
entitled to the fee for its services provided for in the Prior Agreement from
(but exclusive of) the date hereof until the termination of this Agreement,
except as provided in Section 3 below.

     Section 3. In the event that this Agreement is not approved by a majority
of the Trust's outstanding voting securities (as such term is used in the
Investment Company Act), Pioneer shall be entitled to a fee equal to the cost to
Pioneer of performing its services under this Agreement in lieu of the fee
provided for in Section 2. For purposes of this Agreement, Pioneer's costs in
providing the services under this Agreement shall be equal to the pro rata
portion of Pioneer's expenses for the term of this Agreement attributable to its
investment company advisory business, calculated as follows: Pioneer cost in
providing investment advisory services to its investment companies of the same
type (i.e., domestic equity, international, fixed income, money market)
multiplied by a fraction the numerator of which shall be the average daily net
assets of the Fund during the term of this Agreement and the denominator of
which shall be the average month end net assets under Pioneer's management of
all of its investment company clients.

     Section 4. The compensation earned by Pioneer under Section 2 of this
Agreement shall be held in an interest bearing escrow account with the Fund's
custodian. If a majority of the outstanding voting securities approves this
Agreement prior to the end of its term, the amount in the escrow account

            Exhibit C -- Additional Information Pertaining to Pioneer


PORTFOLIO TRANSACTION POLICIES

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

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

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

     In circumstances where two or more broker-dealers offer comparable prices
and executions, preference may be given to a broker-dealer which has sold shares
of a fund as well as shares of other investment companies managed by Pioneer.
This policy does not imply a commitment to execute all portfolio transactions
through all broker-dealers that sell shares of the fund.

     None of the funds used any brokers affiliated with Pioneer during its most
recently completed fiscal year in connection with its portfolio transactions.

           Exhibit D -- Portfolio Manager's Discussion of Performance

Report From the Fund Managers
Safeco Balanced Fund
As of June 30, 2004

How did the Fund perform?

     The Safeco Balanced Fund underperformed its benchmark -- a 60/40 mix of the
Russell 1000 Value and Lehman Aggregate Bond indices, for the six-month period
ending June 30, 2004.

What factors impacted the Fund's performance?

     The two dominant factors effecting performance over the past six months
were the rise in interest rates in the second quarter, and the dramatic
outperformance of smaller, lower-quality stocks in the first quarter. Higher
interest rates caused a decline in fixed-income assets over the past three
months, resulting in an essentially flat bond market over the six-month period.

     Rising interest rates also had a negative impact on financial stocks, our
largest equity sector. Asset allocation had a favorable impact, as 64.9% of the
assets were invested in equities, which had a somewhat higher return than fixed
income assets year-to-date. This allocation is toward the upper end of our
allowable range of 50% to 70% equity exposure. Year-to-date both stocks and
bonds lagged their respective indices. Most of the underperformance in equities
occurred early in the year, when lower quality stocks performed exceptionally
well.

     For the year-to-date, the Fund's best-performing sector was energy, which
returned around 10%. Performance here was led by Conoco-Philips, up nearly 20%,
and British Petroleum, up around 10%. This sector was up primarily due to the
rise in oil prices, and the resulting improved outlook for earnings. Consumer
discretionary stocks were our next best group, returning around 8%. Materials
and consumer staples were our third and fourth best-performing sectors.

     On the negative side, our worst sectors were technology and health care,
both of which declined by around 2%. Technology was hurt primarily by a large
decline in both Nokia and Texas Instruments. Nokia has been losing market share
in the cell phone market, and Texas Instruments is one of their suppliers.
Finance stocks, the largest sector in both our index and the Fund, were held
back by the negative impact that rising interest rates are expected to have on
earnings. This essentially led to flat performance for the six-month period.

     The bond portion of the Fund benefited from a relatively short duration of
4.48 compared to the 4.7 duration of the Lehman Aggregate Index. This is because
longer duration bonds declined more than shorter ones after rates began rising.
The Fund also benefited from being underweight in Treasury securities, as
Treasuries were the worst-performing sector of the bond market for the six-month
period.

     We were hurt in the fixed-income portion of the portfolio by being
underweight in mortgages, which were the bond market's best-performing sector.
Being overweight in corporate debt also negatively impacted performance, even
though we were mostly overweight in A-rated bonds, which performed better than
lower-quality bonds.

What changes did you make to the Fund and why?

     During the past six months, we made several changes to the equity portion
of the Fund. As always, the changes were designed to own the stocks we find most
attractive and to adjust sector weightings to what we believe are appropriate
levels.

     Stocks added to the portfolio included PMI Group, Weyerhaeuser, and Polaris
Industries. PMI Group, a mortgage insurer, was added because it's a rarity among
financial stocks in that rising rates should actually help earnings as the pace
of refinancing slows. Weyerhaeuser, a stock we have wanted to own for some time
in order to gain exposure to forest products, finally reached what we believe to
be an attractive valuation. Polaris Industries is a maker of all-terrain
vehicles, a market we expect will continue to experience good growth, especially
as the economy improves and the outlook for jobs gets better. We also initiated
positions in Allstate Insurance, Coca Cola and Illinois Tool Works, all of which
we believe were selling at attractive valuations.

     We eliminated holdings of Disney, which rose after receiving an unsolicited
takeover offer. We also sold Eli Lilly, Anheuser-Busch and Hubbell based on
valuation, as they had appreciated to levels that were very near our target
prices.

     We reduced our position in the finance sector, mainly to reduce our
exposure during what we expect to be a period of rising interest rates. We are
currently marginally underweight in finance relative to the Russell 1000 value
Index. We also reduced our exposure to producer durables due to these stocks
having performed very well. We do however remain overweighted in this sector by
just over 2% as we expect these stocks to continue to perform well as the
economy improves. We are overweight in the materials sector for the same reason,
and



                                      D-1



have added to our position in this sector, primarily by buying Weyerhaeuser as
discussed earlier. We also added to our exposure to what Russell calls "other"
(primarily includes multi-industry companies, such as GE), as this sector went
from 1.6% to 6.6% of the index at the June re-configuration.

     In the fixed income portion of the Fund, over the past six months we
increased our holdings in corporate debt, where we are overweight. We also added
to our holdings in government debt, while decreasing the portion of the assets
invested in mortgages. We also reduced the duration of the bonds, and currently
have a lower duration than the index.

Report From the Fund Managers
Safeco Core Equity Fund
As of June 30, 2004

How did the Fund perform?

     The Safeco Core Equity Fund underperformed its benchmark Index, the S&P
500, for the six-month period ending June 30, 2004.

What factors impacted the Fund's performance?

     Trends that hurt the Fund in the fourth quarter of 2003 continued. Cyclical
stocks, companies without earnings, and lower-quality companies continued to
perform better than the stocks in the Fund's benchmark.

     During the first half of this year, virtually every sector had stocks that
performed well. Some of these stocks, such as Ball Corp., Illinois Tool Works
and Leggett & Platt performed well as the economy strengthened. Others like
Hartford Financial and Schlumberger performed well because trends in the
insurance and energy industries remained positive. Finally, others like Estee
Lauder, Harley Davidson and PepsiCo are simply solid companies that continue to
do well.

     The Fund had several poor performing stocks in the first half, including
some in the health care sector. In this sector, patent expirations (Abbott),
legal issues (Wyeth) and concerns regarding future growth rates (Amgen) weighed
on the stocks. The technology sector had several losers. Nokia is suffering from
newer entrants and its own product cycle. Texas Instruments and Applied
Materials remain volatile due to concerns regarding the strength and length of
the cycle in their end markets.

What changes did you make to the Fund and why?

     Diversification is increasing -- we added two utilities stocks. The largest
position sizes are decreasing: positions over 3% at year-end 2003 are down to
zero at mid-year. The percentage of the funds in its top-10 holdings is
decreasing (28.2% at year-end 2003 versus 24% now) and the average market
capitalization is decreasing, achieved by reducing positions in Citigroup and
Pfizer. The intent of these moves is to improve the relative performance of the
Fund.

     At the same time we were undertaking the activities outlined above, we
continued to look for the correct buy and hold stocks for the Fund. This
included such moves as adding to existing positions in Illinois Tool Works and
Cardinal Health and initiating new positions, such as in SunGard Data Systems
and Best Buy.

     We eliminated our position in Altria when it reached our price objective,
as well as our position in PeopleSoft, because we found a better alternative.

Report From the Fund Managers
Safeco Growth Opportunities Fund
As of June 30, 2004

How did the Fund perform?

     The Safeco Growth Opportunities Fund outperformed its benchmark index, the
Russell 2000 Index[RegTM], for the six-month period ending June 30, 2004.

What factors impacted the Fund's performance?

     The biggest factor affecting the Fund's strong performance has been from
stock selection. We have many stable, liquid and less volatile small-cap
holdings. Our view continues to be that earnings growth comparisons for many
companies will moderate as the economy continues to recover, thus we have
positioned the portfolio toward companies with sustainable growth in earnings.

     Some of the Fund's outperformance was a result of 46% of the Fund having a
market capitalization of greater than $1 billion currently. This is the segment
of the market-cap spectrum that we added to during late 2003. Year-to date, the
Russell 2000 Index[RegTM] sectors that contributed the most were producer
durables, consumer discretionary and healthcare -- all overweighted sectors in
the Fund. Our underweight in technology helped as well.

What changes did you make to the Fund and why?

     The turnover in the Fund remains quite low for a small-cap fund, as
compared to the turnover of other funds of its type. What this symbolizes is a
management team with a long-term view of the investments made in the portfolio.

     We continue to upgrade the quality of the portfolio to more stable, more
liquid and thereby less volatile stocks. We seek high quality companies that
have consistent growth in profits, strong return on investor capital (or
increasing), an ability to fund growth internally, and a seasoned management
team.

Report From the Fund Manager
Safeco International Stock Fund
As of June 30, 2004

How did the Fund perform?

     The Safeco International Fund underperformed its benchmark index, the MSCI
EAFE Net Index, for the six-month period ending June 30, 2004.

What factors impacted the Fund's performance?

     Against a backdrop of improved economic conditions, global equity markets
posted moderate gains in most instances for the first six months of 2004.
However, concern about the future sustainability of the economic improvement,
peaking of the corporate profit cycle, rising interest rates, persistent
geopolitical strains and the ascent in the crude oil price counteracted some of
the gains in stocks.

     The American and Japanese economies -- the world's largest and second
largest -- and China, produced much of the economic vigor. These economies also
provided the tonic for the rest of the world that buoyed corporate earnings'
prospects and underpinned the equity markets' advance.

     Performance of the Fund was mixed over the first half of the year. Some of
the factors that weighed on performance during 2003 persisted while others
dissipated. Smaller companies continued to outperform their larger peers during
the first half of 2004. This continues to negatively impact the Fund as our
focus is large-cap companies.

     However, encouragingly, we have begun to see a broadening out of
performance in the markets. Many of the low quality, "recovery play" stocks
which led the markets last year have begun to lag and high quality companies
which generate consistent earnings growth have begun to come back into favor.

     Lastly, the Fund was held back somewhat by its underexposure to the
strongly performing Japanese market, however, as evidenced by the Fund's
increased weighting in Japan and greater Asia, we are encouraged by developments
in the region.

What changes did you make to the Fund and why?

     There was considerable activity in the Fund during the first half of the
year, with much of the activity occurring in the Asia region. The Fund's
exposure to a particular country or sector is strictly a residual of the stock
selection process; however we have identified a number of attractive investment
opportunities in Japan and Asia in general.

     Several Japanese financial services companies were added to the Fund
including, Sumitomo Mitsui Financial Group NPV, Millea Holdings Incorporated NPV
and Mitsui Sumitomo Insurance Company. The recovery in the Japanese economy
continues to gain momentum and, more importantly the underlying causes appear to
be more structural rather than cyclical and therefore more sustainable.
Financial services companies should be among the beneficiaries of this recovery.

     Similarly Hong Kong banking group Hang Seng Bank was added to the fund.
Hang Seng Bank is one of the largest financial services companies in Hong Kong
and is well placed to benefit from the recovery in the Hong Kong economy as well
as the strong growth in mainland China where it is the largest foreign investor
in any Chinese bank.

     During the second quarter, Japan Tobacco and Taiwan Semiconductor (TSMC)
were added to the Fund. Japan Tobacco is the dominate tobacco company in Japan
and owns the international rights to three of the top six global cigarette
brands. There is potential for re-rating of the stock as management pursues a
number of restructuring initiatives. TSMC is a global leader in the design and
manufacture of integrated circuit chips. The company is well positioned to
benefit from the growth in outsourcing of chip manufacturing yet trades on an
attractive multiple relative to its peers and historical growth record.

     Positions disposed of during the period include Lloyds TSB, Shell T&T and
China Life. Shell's announcement that it has overstated proven reserves by 20%
raised a credibility issue about the management and we felt better opportunities
were available elsewhere. We participated in the IPO of China Life in December
of 2003. Shares in the company soared shortly thereafter making the stock look
expensive in our view.

     Although Lloyds TSB is the highest yielding of the U.K. banks, we had
concerns regarding the sustainability of the dividend given the potential need
for capital support for its insurance subsidiary, Scottish Widows. Further, we
believe that other financial companies, in particular Royal Bank of Scotland and
BNP Paribas (also purchased during the period) are more attractive at this time.

Report From the Fund Managers
Safeco Large-Cap Growth Fund
As of June 30, 2004

How did the Fund perform?

     For the six-month period ending June 30, 2004, the Safeco Large-Cap Growth
Fund underperformed its benchmark, the Russell 1000 Growth Index.

     The Fund's performance since inception in late 2001 also trails its
benchmark, although the majority of the Fund's underperformance since inception
occurred in calendar year 2003, when smaller stocks with no earnings and
speculative characteristics significantly outperformed the overall market.
Conversely, stocks with better fundamentals such as high levels of profitability
and balance sheet strength underperformed in 2003. This provided a major
headwind to our quality investment style. While volatile conditions may persist
near term, we believe that we are in the midst of a transitional phase, into an
environment in which investors again return to high quality large cap stocks
with sustainable growth characteristics.

What factors impacted the Fund's performance?

     Many companies have been demonstrating very strong fundamentals and
exceptional earnings growth. Returns have been muted, however, due in part to
investor anxieties regarding inflation, rising interest rates, slowing growth in
China, the Iraqi Government transition, terrorism, near record oil prices and
the upcoming presidential election.

     Returns were helped most by internet software and services holdings, while
the largest detractors from returns came from software. Individual stocks that
had a major impact on performance included:

     o    Yahoo! Inc. appreciated by 62% over the half-year, helped by increases
          in paid search activity and online advertising, along with a growing
          user base.

     o    Avon Products was also a top performer, benefiting from growth in
          developing markets such as central/eastern Europe, Latin America, and
          China.

     o    Software storage firm Veritas lost 25% over the period, and recently
          announced that revenues and earnings would come in below investor
          expectations. We trimmed our holding in the stock and are monitoring
          developments closely.

What changes did you make to the Fund and why?

     The relatively flat first half returns masked an erratic period in which
market leadership shifted frequently between cyclical and defensive areas of the
market. Since the beginning of the year, we reduced our holdings of technology
stocks, and the Fund is now slightly underweight in technology. We also took
profits in some areas of health care, notably in health care equipment and
supplies. Some proceeds were re-deployed into biotechnology. The Fund's largest
position remained with the global, research-based pharmaceutical firm, Pfizer
Inc.

     Energy was one of the best performing segments in the Fund, appreciating by
over 25%. We continue to like the operating environment for several energy and
oil services companies, which are indirectly benefiting from high oil and gas
prices, limited supply growth and increasing demand associated with the global
economic recovery. Accordingly, we added to this sector over the period, and
hold an overweight position here.

Report From the Fund Managers
Safeco Large-Cap Value Fund
As of June 30, 2004
How did the Fund perform?

     The Safeco Large-Cap Value Fund underperformed its benchmark, the Russell
1000 Value[RegTM] Index, for the six-month period ending June 30, 2004.

What factors impacted the Fund's performance?

     The Fund's performance was primarily due to stock selection and aided by a
one-time settlement of a class action lawsuit regarding a former holding.

     As usual, there were multiple factors affecting performance. One factor
that has helped so far this year, after hurting last year, was the relative
outperformance of large companies over smaller ones. This helped the Fund's
relative performance as we own mostly larger companies. It also helped that
higher quality companies tended to perform better than lower quality ones. This
too is a change from recent periods.

     For the year-to-date, the Fund's best performing sector was energy, which
returned around 10%. Performance here was led by Conoco-Philips, up nearly 20%,
and British Petroleum, up around 10%. This sector was up primarily due to the
rise in oil prices, and the resulting improved outlook for earnings. Consumer
discretionary stocks were our next best group, returning around 8%. Materials
and consumer staples were our third and fourth best performing sectors.

     On the negative side, our worst sectors were technology and health care,
both of which declined by around 2%. Technology was hurt primarily by a large
decline in both Nokia and Texas Instruments. Nokia has been losing market share
in the cell phone market, and Texas Instruments is one of their suppliers.
Finance stocks, the largest sector in both our Index and the Fund, were held
back by rising interest rates and the negative impact this is expected to have
on earnings. Finance stocks were essentially flat for the past six months.

What changes did you make to the Fund and why?

     During the past six months, we made several changes to the Fund. As always,
the changes were designed to own the stocks we find most attractive and to
adjust sector weightings to what we believe are appropriate levels. Some recent
sector weighting adjustments were due to the annual Russell Value Index
re-configuration which occurred at the end of June.

     Stocks added to the portfolio included PMI Group, Weyerhaeuser, and Polaris
Industries. PMI Group, a mortgage insurer, was added because it's a rarity among
financial stocks in that rising rates should actually help earnings as the pace
of refinancing slows. Weyerhaeuser, a stock we have wanted to own for some time
in order to gain exposure to forest products, finally reached what we believe to
be an attractive valuation. Polaris Industries is a maker of all-terrain
vehicles, a market we expect will continue to experience good growth, especially
as the economy improves and the outlook for jobs gets better. We also initiated
positions in Allstate Insurance, Coca Cola and Illinois Tool Works, all of which
we believe were selling at attractive valuations.

     We eliminated holdings of Disney, which rose after receiving an unsolicited
takeover offer. We also sold Eli Lilly, Anheuser-Busch and Hubbell based on
valuation, as they had appreciated to levels that were very near our target
prices.

     We reduced our position in the finance sector by 2.1%, mainly to lessen our
exposure during what we expect to be a period of rising interest rates. We are
currently 1.7% underweight in finance relative to the Russell 1000 Value Index.
We reduced our exposure to stocks in the producer durables sector, which
performed very well. We do, however, remain overweighted in this sector by 2.0%
as we expect these stocks to continue to perform well as the economy improves.
We are overweighted in the materials sector for the same reason, and have added
to our position, primarily by buying Weyerhaeuser as discussed earlier. We also
added to our exposure to what Russell calls "other" (primarily includes
multi-industry companies, such as GE), as this sector went from 1.6% to 6.6% of
the Index at the June re-configuration.

Report From the Fund Managers
Safeco Multi-Cap Core Fund
As of June 30, 2004

How did the Fund perform?

     The Safeco Multi-Cap Core Fund outperformed its benchmark Index, the
Russell 3000[RegTM] Index, for the six-month period ending June 30, 2004.

What factors impacted the Fund's performance?

     The market posted a modest gain during the first half of the year as the
improving economy and strong corporate earnings outweighed investors' concerns
about rising rates, the conflict in Iraq and higher oil prices.

     During the period, small- and mid-cap stocks outperformed large-cap stocks.
In the first half of this year, the Russell 2000[RegTM] Index of small-cap
stocks advanced 6.76% and the Russell Mid-Cap Index advanced 6.67% versus a 3.3%
rise in the Russell 1000[RegTM] Index of large-cap issues.

     We attribute our better performance in the period to the Fund's high
exposure to mid- and small-cap stocks relative to the benchmark.

What changes did you make to the Fund and why?

     During the first half we continued our strategy of increasing
diversification to improve the risk/reward trade-off in the Fund. We added 17
new positions, and deleted six, bringing our total number of names to 73. The
additions were mostly economically sensitive companies in the mid-cap size
range. The deletions were all small-cap companies which had not been performing
well. We continue to seek a better balance among market capitalizations as we
modestly reduce our exposure to small-caps relative to our benchmark.

     Four of the five top performers for the period -- Coldwater Creek,
Starbucks, Expeditors International and Nordstrom -- are cyclical companies. Our
poor performers were either companies that had company-specific problems, like
Performance Food Group, Intuit and Penwest Pharmaceutical, or stocks that
retreated after a good run, like Primus Knowledge.

Report From the Fund Manager
Safeco Small-Cap Value Fund
As of June 30, 2004

How did the Fund perform?

     Overall the Fund essentially matched the performance of our benchmark
Russell 2000 Value index for the six-month period ending June 30, 2004. All the
positive contributions took place in the first quarter, and then the small-cap
market seesawed down and up from April through June. In retrospect, the first
few months were a continuation of the "take off" phase of the market cycle that
began last March. The April/May timeframe saw the first significant correction
since that rally began.

What factors impacted the Fund's performance?

     Market leadership by higher quality stocks has continued, following a trend
that began in the fourth quarter of last year. I define high quality as
companies with stock prices above $5 per share, with positive earnings, low P/E
ratios versus the universe, and market capitalization above $250 million.

     This trend helped the Fund, since it owns stocks all across the
small-cap-size spectrum and the weighted average tends towards the middle of the
small-cap-size range. Also, the Fund has less of its assets invested in
companies that are not currently more profitable than the index, and we didn't
have much exposure to under-$5 price stocks.

     In early April, one single government report of job growth was all it took
to crystallize the market's worry that the Federal Reserve would start raising
short-term interest rates. This precipitated a fast and steep correction in the
Fund's most interest-rate-sensitive stocks. Those stocks have made a partial
recovery since then.

What changes did you make to the Fund and why?

     I added new stocks, which I believed were not discounting their full
potential or had not participated in the "lift off" phase of the early market
cycle. From the March 2003 bottom, the entire market experienced a "rising tide"
effect. That effect has run its course, and so I've tried to find stocks that
represent value opportunities in the traditional sense of the word.

     For example, Pacer International was bought on price weakness after I had
multiple meetings with management to cement an understanding of their business.
Pacer arranges for the transportation of ocean freight containers by reselling
space on the railroads in a service called the Stack Train. They produce
significant free cash flow, but their service offering is aligned with the Union
Pacific and CSX railroads, and those companies are experiencing a period of poor
service quality that has temporarily hurt Pacer. In time this will change.
However, Pacer's stock was down based on the current view of conditions, not
what they'll be in the future. The future is where I see the stock's
opportunity.

     I also exited positions that I believe have run their course, or have taken
a turn for the worse. Examples of the former include the last of the utility
preferred stocks in the Fund. An example of the latter would be the company
Osteotech, which abandoned one of its product lines in January, calling into
doubt its growth prospects and valuation. I was fortunate to exit the stock
before the worst of the damage was done.

     I continue to believe stocks with traditional "value" characteristics, in
terms of their overall valuation and free cash flow generation, are a successful
strategy to own for the long term. I am a believer in owning stocks that are
priced cheaper than the overall market, and that have sustainable businesses and
cash flows. I think the Fund is currently positioned this way.

Portfolio Manager's Discussion 6/30/04

     While the economy grew and corporate profits rose during the first half of
2004, stock market returns were muted by worries about rising interest rates as
well as geopolitical issues around the world. In the fixed income markets, the
jump in interest rates midway through the six months sent many bond prices
lower, resulting in weak returns in most sectors. In the following interview,
Timothy Mulrenan, who is responsible for the equity portfolio of Pioneer
Balanced Fund, and Richard Schlanger, who is responsible for the Fund's fixed
income portfolio, discuss the markets and their investment strategies during the
six months ended June 30, 2004.

Q:   How did the Fund perform during the first six months of 2004?

A:   Pioneer Balanced Fund's Class A shares had a total return of 1.59% during
     the six months ended June 30, 2004, while Class B and Class C shares
     returned, respectively, 1.18% and 1.06%, all at net asset value. During the
     same six months, the average return of the funds in Lipper's Balanced Fund
     category was 1.79%.

Q:   What were the factors that affected performance?

A:   The domestic equity market produced generally positive returns for the six
     months, but those returns masked the underlying volatility and tensions
     between conflicting influences. Supporting equity valuations were an
     expanding economy and robust corporate profits. Reported earnings tended to
     be 25% higher than in the comparable period of 2003. The competing negative
     factors included the spike in market interest rates midway through the six
     months, as well as uncertainty brought on by concerns over issues such as
     energy prices, stability in Iraq and presidential election-year politics.

     In the fixed income markets, interest rates tended to rise, with
     shorter-maturity rates rising farther than longer-term rates. The price
     losses brought on by the higher rates as well as the flattening of the
     yield curve -- or difference between short-term and long-term yields --
     resulted in volatility in the bond market. The key factor was the widely
     anticipated announcement by the Federal Reserve Board on the final day of
     the period to begin tightening monetary policy by starting to raise the
     influential overnight lending rate -- the Fed Funds rate. The initial hike
     was from 1.00% to 1.25%, but the expectation was that the Fed would raise
     rates further in the months to come in an effort to guard against
     inflationary pressures.

Q:   What were the principal strategies during the period?

A:   We kept the allocation between equities and bonds consistent during the six
     months. On June 30, about 64% of assets were invested in stocks -- about
     the same percentage as at the start of the period. The remaining assets
     were invested in fixed income assets, including corporate bonds, government
     securities, and mortgage-backed securities, with a small allocation in
     foreign bonds and less than 2% in cash. There also were no major changes in
     the equity portfolio, although we did trim our energy position to take
     profits and to reduce our vulnerability to the area during a time when we
     expected increased price volatility. We remained over weighted in energy
     stocks, however, and remain positive about the sector's longer-term
     fundamentals. We modestly increased the Fund's health care holdings, adding
     medical device company Guidant and pharmaceutical company Eli Lilly. We
     thought Guidant's stock price had become compellingly attractive after it
     fell because of an announcement about a delay in a new product
     introduction. We like Lilly because it has well-developed research and
     development activities that should produce a flow of new products. In
     addition, we initiated a position in Liz Claiborne, the apparel company. We
     think it is attractive because of its strong distribution during a time
     when the industry is beginning to gain greater control over pricing. We
     substantially reduced our holdings in two stocks that had performed very
     well -- software company Symantec and auto insurance company Progressive.
     We also eliminated our position in Devon Energy, an exploration and
     production company, because of our concerns about its internal cost
     structure. In the fixed income portfolio, we raised overall quality of the
     portfolio, with average credit quality moving from A+ to AA-. Interestrate
     sensitivity -- as measured by duration -- was about even with that of the
     benchmark Lehman Brothers Aggregate Bond Index, although it declined
     slightly during the six months from 4.52 years to 4.34 years. We increased
     our exposure to mortgage-backed securities -- the best-performing part of
     the investment-grade sector -- from 43.6% of fixed income assets to 47.7%.
     Mortgages tend to be less vulnerable to declining prices than Treasuries
     and other government securities in a rising interest-rate environment. We
     reduced our exposure to corporates, taking profits when their yield
     advantage over Treasuries began to narrow. At the end of the period, 25.9%
     of the fixed income portfolio was invested in industrial and utility bonds,
     compared to 31.4% at the start of the period. At the same time, we also
     reduced our banking and financial services bond holdings from 10.7% to 9.0%
     of fixed income assets. When we invest in corporates, we tend to favor new
     issues, which have a greater yield advantage over Treasuries than existing
     issues available on the secondary market. When invested in Treasury bonds,
     we tended to hold TIPS, or inflation-protected Treasuries, although we sold
     them near the end of the period when the Federal Reserve made it clear it
     intended to control inflationary pressures.



                                      D-19



Q:   What types of investments had the greatest influence on performance?

A:   In our equity portfolio, our emphasis on consumer staples companies helped
     considerably as stock investors began to recognize the value of
     higher-quality, stable growth companies that had been overlooked in the
     rally of 2003. Holdings such as Gillette, PepsiCo and Wrigley performed
     very well. Our technology positions also did well, led by Symantec, whose
     share price went up 27% during the six months. Detracting from performance,
     however, was security selection in the consumer discretionary sector.
     Family Dollar Stores had disappointing earnings, which may have been caused
     by higher gasoline prices, but we still favor the company and continue to
     hold it at the end of the period. Newmont Mining, which had been a strong
     contributor to Fund performance prior to the period, fell 20% during the
     period in response to slumping gold prices. However, we still believe the
     company is attractive and continue to hold a position in it on June 30.

     In the fixed income portfolio, our overweight position in mortgages helped
     substantially, as did our exposure to corporate bonds -- both high yield
     and investment-grade. Performance was held back, however, by our
     concentration in intermediate-term securities, as short- and
     intermediate-term interest rates rose more than the rates on long-term
     bonds during the six months.

Q:   What is your investment outlook?

A:   We believe the June 30 announcement by the U.S. Federal Reserve that it was
     starting to raise short-term rates is the start of a long process of
     interest-rate hikes that is likely to continue at least through the end of
     2005. We anticipate moving to a barbelled strategy over time with respect
     to maturity allocations, concentrating on both short-term securities and
     long-term bonds while de-emphasizing intermediate-term bonds that we think
     are most vulnerable in the present environment. We believe the equity
     market will continue to be choppy, with no major trends either up or down
     in stock price averages. The outlooks for gross domestic product (GDP) and
     for corporate earnings both are favorable, although the rate of corporate
     profit growth may slow somewhat. The big question hanging over investors'
     minds will be what happens to interest rates. In addition, uncertainty
     about geopolitical events and the outcome of the presidential election will
     influence investor psychology. We think the most likely scenario is that
     the major stock averages will show moderate growth over the next several
     months.

Portfolio Manager's Discussion 6/30/04

     In the following discussion, portfolio manager John Carey, reviews the
investment environment and the performance of Pioneer Fund over the six months
ended June 30, 2004.

Q:   How did the portfolio perform over the first six months of 2004?

A:   Pioneer Fund recorded a positive total return of 2.03% at net asset value
     on Class A shares in the six months ended June 30, 2004. Class B, C, R and
     Y shares returned 1.59%, 1.63%, 2.03% and 2.27% at net asset value. That
     exactly matched the return of the average fund in the Lipper Large-Cap Core
     group, which was also up 2.03%. Both Pioneer Fund and the Lipper average
     lagged the Standard & Poor's 500 Index, which showed a total return of
     3.44% over the same period. While the mild returns might suggest a calm
     market, the reality was a market of sharp contrasts. With reference to
     performance of the respective sectors in the S&P 500, information
     technology, the darling of investors in 2003, barely moved, with a gain of
     0.44% for the period, while energy, industrials and consumer staples
     advanced, respectively, 12.97%, 7.42%, and 6.12%. Investors appeared to be
     "rotating" out of more highly priced stocks and into shares more moderately
     priced, with dividends and steadier earnings outlooks.

Q:   Please discuss the Fund's performance versus the S&P 500 Index.

A:   Our underperformance versus the S&P 500 was attributable mainly to our
     stock holdings in four sectors: information technology, materials,
     industrials and telecommunications services. Our strongest positive
     contributors were our investments in consumer discretionary, consumer
     staples and health care. Taking first the negative contributors, our
     technology holdings showed an overall decline of 1.59% versus the S&P 500
     sector gain of 0.44%. The main culprits were our positions in Texas
     Instruments, Novellus Systems, Synopsys and Nokia. After analyzing the
     different situations, we retained shares in Texas Instruments and Nokia,
     but liquidated our positions in Novellus and Synopsys. With regard to
     materials, where again we showed a negative return (3.80%) versus a slight
     positive return (0.71%) for the S&P 500 sector, the largest factor was our
     position in Rio Tinto. In the case of materials, we believe that the
     fundamentals are strong for the group looking out at least over the next
     couple of years and that it was mainly "profit taking" behind the weak
     share prices. Perhaps, too, there was some concern about a potential
     slow-down in the Chinese economy, which has been a prime user of many raw
     materials as that country rapidly industrializes. Following our evaluation
     of the pros and cons, we retained Rio Tinto, a prominent worldwide mining
     company, as well as our shares of other companies in the sector.
     Industrials presented a mixed picture, with our investments rising 5.13%
     versus an increase for the sector of 7.42%. We had very good performance
     from our railroad holding Norfolk Southern, but our capital-goods stocks
     were more sluggish. Finally, in telecommunication services, we did not own
     AT&T Wireless, which received a premium take-over bid, but instead owned
     BellSouth and SBC Communications, the companies in the joint venture
     Cingular, that made the bid. BellSouth and SBC both declined as investors
     worried that they "overpaid." On the bright side, we had some nice gains
     from stocks in consumer discretionary, consumer staples and health care.
     They were, respectively, John Wiley & Sons, publisher of scientific and
     technical books and journals and also owner of the "For Dummies" imprint;
     Colgate-Palmolive, major brand in toothpaste; and Becton Dickinson,
     provider of medical supplies including disposable syringes.

Q:   What changes have you made to the portfolio so far this year?

A:   We were fairly active during the six months, adding 18 positions and
     eliminating 18. The combined effect of securities transactions and market
     fluctuations produced overall increases for our weightings in the energy,
     consumer discretionary, consumer staples, health care and financials
     sectors; overall decreases for our weightings in industrials and
     information technology; and no meaningful change for our weightings in
     materials, telecommunications services and utilities. In energy, we
     initiated positions in Apache, British Petroleum, Pioneer Natural Resources
     and Occidental Petroleum and sold positions in Transocean, Royal Dutch
     Petroleum, and Shell Transport & Trading. We believed that Transocean was
     fairly valued, and in the cases of Royal Dutch and the allied Shell
     Transport we had developed reservations about management in the wake of
     significant downward revisions in oil and gas reserves estimates. On the
     other hand, we thought that prospects were positive for the companies we
     added and that the larger number of holdings would provide the portfolio
     with more diversification. In consumer discretionary we invested in three
     companies we thought were poised to do better with the stronger economy,
     Ford Motor, Liz Claiborne, and Walt Disney, and sold two stocks that had
     been longer-term disappointments, Dow Jones and Eastman Kodak. We also
     added Clorox, formulator of bleaches and other household cleansers, and
     Estee Lauder, cosmetics manufacturer, in consumer staples. Our health care
     additions were among our most significant and included equipment makers
     Guidant and St. Jude Medical, distributor Cardinal Health, and generic-drug
     companies Barr Pharmaceuticals and Mylan Laboratories. One of our purchases
     in financials proved to be particularly well timed, as South Trust, a
     regional bank headquartered in Birmingham, Alabama, received a generous
     acquisition offer from another bank, Wachovia, not long after we had bought
     it. Another entry we made to the portfolio was U.S. Bancorp, based in
     Minneapolis, Minnesota. In other sectors, we bought, in materials, Ecolab,
     supplier of industrial and institutional cleaning chemicals, and, in
     information technology, Apple Computer, survivor, against all odds, in the
     personal-



                                      D-22



     computer business as well as innovative producer of the very hot iPod
     digital-music player. Along with the seven names already mentioned in
     energy and consumer discretionary and (above) in information technology, we
     deleted the following: Boeing, Lockheed Martin, Robert Half, Union Pacific,
     Medco Health Solutions, Bank of America, Electronics Data Systems, BMC
     Software, Cisco Systems, QUALCOMM and Altera. As always, we had a variety
     of reasons, in some instances recognizing difficulties for the companies
     that appeared beyond a reasonable time horizon in their resolution, in
     other instances seeing a fully valued stock relative to identifiable
     earnings power, and in still other cases just thinking we had more
     attractive alternatives.

Q:   What is your outlook on the stock market and economy for the remainder of
     2004?

A:   At the midpoint of 2004, the market appears in disarray. Truth be told,
     interest rates have not really moved very much at all, but there appears
     great anxiety about greater moves to come. Inflation is not a current
     problem, yet the high oil and raw-materials prices, as well as the prospect
     of rising wages with growth in employment, provide the worriers a reason to
     focus on the risk of inflation. Corporate earnings are generally very
     strong and also strongly up from last year, but the expressed concern is
     with respect to slowing of the impressive comparisons. And so it is as well
     when it comes to discussion of international events and
     corporate-governance issues and much else: every glass on the counter seems
     to be half empty, none are thought to be half full, as the common
     expression goes. From our point of view, a half glass of water is just
     that, and the market to us remains attractive, even if more moderately
     attractive than it was in early 2003 then prices were much lower and the
     economy was still just poised for its rebound rather than underway with the
     rebound as it is currently. We see especially good values, however, among
     the good companies with good long-term records in which we like to invest
     on your behalf and which were relatively neglected by investors up until
     recently.

     Betting which way the market might go on a short-term basis has never
     seemed to us like a particularly fruitful endeavor. For one thing, what is
     to be gained from that activity unless one is just speculating, for
     example, in market-index futures, an activity we would not recommend to any
     but the real gamblers. For in the actual day-to-day world, one makes or
     loses money on individual stocks bought and sold, embraced or avoided. One
     never makes a dime guessing which way the market will go; it is the actual
     investments one does or does not make that determine your results. So our
     intention is, as always, to stay invested over the coming months, and
     years, and to stay invested in the solid kinds of companies we always aim
     to own in your portfolio. Thank you for your support.

Portfolio Manager's Discussion 3/31/04

     Investor optimism lifted international markets during the 12 months ended
March 31, 2004. The upbeat mood was supported by a resurging Japanese economy
and stronger-than-expected job growth in the United States, both of which are
expected to be positive for the European economy. As Stefano Pregnolato, the
Fund's lead portfolio manager, mentions in the following interview, the rally
was broad based -- led by cyclical stocks and lesser quality companies that had
underperformed in the multi-year correction in equity markets.

Q:   How did the Fund perform during the rally?

A:   The positive trends that we witnessed in the first half of Pioneer
     International Equity Fund's fiscal year continued into the second half.
     However, the momentum for global economic growth shifted to Asia in the
     first quarter of 2004. Investors are looking more favorably upon Japan and
     its economy, which is showing signs of resurgence. For the 12 months ended
     March 31, 2004, the Fund's Class A, B and C shares posted gains of 50.77%,
     49.32% and 48.85% at net asset value, respectively. In comparison, the
     Morgan Stanley Capital International (MSCI) EAFE Index grew 57.54% for the
     same period. We believe the Fund's relative underperformance to this
     benchmark is the result of two factors. First, Japanese stocks appreciated
     strongly during the first quarter of 2004. The Fund's investments in
     Japanese stocks, although significant at 21.5% of total assets on March 31,
     remained below that of the benchmark throughout the fiscal year -- thereby
     limiting the degree of its relative performance. While we think the
     economic recovery in Japan is a welcome development, we believe it's too
     early to know if Japan has turned the corner. We may consider increasing
     the Fund's exposure there, once we're convinced that Japan is solidly on
     the road to recovery.

     Secondly, the rally in international markets has benefited cyclical stocks,
     that is, companies whose fate is closely linked with the strength of
     economic growth, as well as lower-quality investments. Your Fund has a
     considerable exposure to cyclical stocks, which was very beneficial during
     the fiscal year. However, we refuse to be tempted by short-term trends or
     invest in lower-quality companies just because they are selling at steep
     discounts today. Rather, we invest for the long term, selecting the
     highest-quality, financially sound companies that meet our strict
     investment criteria.

Q:   What is contributing to the rise of Japanese stocks?

A:   After a multi-year recession, the outlook for Japan is improving. Japanese
     consumers are increasing their spending, businesses are buying more
     equipment, and trade with other Asian countries experiencing good growth is
     strong. All these factors are attracting foreign investors and driving
     Japanese stock prices higher. Midway through the fiscal year, Japanese
     investments represented 9.4% of total assets. By the close of the fiscal
     year on March 31, Japanese holdings had climbed to 21.5% of assets through
     price appreciation and addition to existing holdings, while we trimmed the
     overall number of Japanese holdings in the portfolio.

Q:   Were you adding domestic or export-oriented stocks in Japan?

A:   We've been adding to positions in both domestic and export oriented stocks.
     Domestic-demand stocks are benefiting from increased consumer spending,
     which is partially supported by the secular trend of a declining savings
     rate. One of the Fund's best performing stocks, Fast Retailing, which sells
     high-end apparel and accessories, was a major contributor to performance
     for the second half of the fiscal year. The stock's dramatic price
     appreciation left the stock overvalued in our estimation, and we sold the
     entire position in January. Food retailer Ajinomoto is a high-quality
     consumer staple holding with defensive qualities that did well leading up
     to the recovery. It has also done well in the rally, but not nearly to the
     degree of Fast Retailing. Generally speaking, prices of consumer
     discretionary stocks, such as Fast Retailing, posted some of the greatest
     gains during the rally -- bolstered by rising consumer confidence and
     spending.

Q:   Are the Fund's Pacific Rim investments outside Japan also doing well?

A:   Yes. Strong fundamentals, robust intra-regional growth and exports combined
     with strong global demand for cyclical investments are supporting our
     decision to overweight investments in the Pacific Rim outside Japan. In
     many sectors, we believe stocks offer better value than in Europe --
     including semiconductor manufacturer Samsung Electronics (South Korea) and
     telecommunications services provider SK Telecom (South Korea).

Q:   Europe still represents the majority of the Fund's holdings. How are these
     investments faring?

A:   All of the global markets rose sharply during the fiscal year, and European
     stocks -- including those held by your Fund -- were no exception. This
     performance is illustrated by the fact that the MSCI Europe Index, a
     commonly used benchmark for the region, rose 53.96% for the 12 months ended
     March 31, 2004. With nearly 70% of the Fund's assets invested in the
     developed markets of Europe, we are maintaining a slightly overweight
     position in European equities relative to the benchmark. We think stock
     price valuations are



                                      D-25



     fair and are supported by strong dividend yields. Growth across Europe is
     more moderate than outside the region, and this fact is discounted in stock
     prices. The appreciation of the euro continues to be a risk for European
     exporters, and we will be closely following the monetary policy of the Bank
     of England and the European Central Bank (ECB) on that front. (Just
     following the close of the fiscal year, the ECB decided to leave rates
     unchanged.)

Q:   Could you name some of the companies that exemplify your strategy?

A:   Much like other world markets, European cyclical stocks posted some of the
     most dramatic gains, including those in the materials, industrial,
     automobile and consumer discretionary sectors. Porsche (Germany) exceeded
     our expectations, as did software producer Indira Systems (Spain). On the
     other hand, capital goods producer Sandvik (Sweden) performed well, but not
     as strongly as the sector in general. Pharmaceutical Schering is another
     stock that underperformed its sector for the year, when news of a product
     patent expiration last summer left the stock trailing many of its peers.

Q:   What is your outlook for the upcoming fiscal year?

A:   During fiscal 2004, we saw a change in market psychology, with investors
     demonstrating a greater appetite for risk. Not only did investors move
     assets from relatively more stable fixed-income investments into equities,
     but within the equity markets from higher-quality companies to more
     leveraged, lower-quality companies.

     Companies that were considered to be in severe financial distress were
     reclassified as recovery stocks. This paradigm shift benefited many stocks,
     particularly in the technology sector, but left other sectors, such as
     consumer staples and health care underperforming. As history has proven,
     this is to be expected in the early stages of a recovery, when economic
     fundamentals improve and the relatively low stock prices begin to look very
     attractive.

     Our outlook for 2004 is quite optimistic. The recovery appears to be well
     on its way, business confidence is high and the cash flow of companies has
     been substantially improved, thanks to successful restructuring and
     de-leveraging enacted over the last two years. We'll endeavor to position
     the Fund in response to this improving economic picture.

Portfolio Manager's Discussion 6/30/04

     The economy continued to grow during the first half of 2004, but the
general investment environment for equities began turning slightly negative as
rising corporate profit trends began to weaken, consumer spending was not as
strong as expected, and markets started anticipating a tighter monetary policy
from the Federal Reserve. In the following interview, Christopher Galizio
discusses the factors that affected the performance of Pioneer Growth Shares
during the six month period ended June 30, 2004. Mr. Galizio is a member of the
Fund's management team.

Q:   How did the Fund perform during the first half of 2004?

A:   For the six-month period ended June 30, 2004, the Fund's Class A shares
     returned -1.31%, while Class B and Class C shares had returns of -1.80% and
     -1.78%, respectively, all at net asset value. For the same period, the
     Russell 1000 Growth Index returned 2.74%, while the average return was
     2.35% for the 639 funds in the Large-Cap Growth Funds category tracked by
     Lipper Inc. (Lipper is an independent firm that measures mutual fund
     performance.)

     The Fund lagged the benchmark Russell 1000 Growth Index as well as the
     Lipper peer group, principally because of the comparatively larger position
     in technology, especially semiconductor companies, early in the six-month
     period.

Q:   What was the general investment environment like during the period?

A:   The overall market sentiment appeared to be turning negative late in the
     six-month period. The stock market surge that had begun in March 2003
     appeared to lose some energy. Several major corporations, including ones in
     the retail and semiconductor industries, began to report earnings
     disappointments, and we saw some weakening in profit trends, notably in the
     consumer and technology sectors. Consumer spending trends, in particular,
     appeared weak as over-extended consumers finally began to retrench from
     their high-spending patterns. As stock market investors anticipated the
     June 30 announcement by the Federal Reserve Board that it would begin to
     tighten monetary policy by raising short-term interest rates, the share
     prices of some consumer-oriented financial institutions began to fade.
     Industrial stocks, however, tended to outperform the overall market.

Q:   What were your principal strategies during the period?

A:   We restructured the portfolio during the period, focusing on large cap
     companies that we believed offered long-term value, above average revenue
     growth, strong returns on capital and reasonable valuations in relation to
     their earnings potential. This strategy led to a reduced emphasis on the
     semiconductor industry and increased weightings in the software, consumer
     discretionary and financial services areas. We reduced our semi-conductor
     holdings, eliminating positions in Applied Materials, Cypress
     Semiconductor, Texas Instruments and Maxim Technology. We did add Taiwan
     Semiconductor, a major manufacturer with an attractive stock valuation.
     Overall, however, semiconductor stocks went from an overweight to an
     underweight position, relative to the benchmark S&P 500. The reduced
     weightings in technology tended to support performance. Conversely, we
     increased the portfolio's emphasis on software companies, adding companies
     such as Macrovision, which has developed a technology to protect DVDs, CDs
     and other disc based products from piracy, as well as Take-Two Interactive,
     the developer of video games, including Grand Theft Auto -- the most
     successful game in history, with a new version soon to be introduced. We
     also added Fair Isaac, which has developed software to help credit card
     companies analyze the credit-worthiness of applicants. Fair Isaac tended to
     detract from performance late in the six-month period as it reported
     disappointing earnings, but we continued to hold it because of its
     attractive valuation. We moved from an underweight to an overweight in the
     consumer discretionary sector, taking advantage of attractive valuations of
     Disney, whose media and theme park properties have improved earnings
     outlooks, and Viacom, the owner of the CBS and MTV television networks
     among other properties. Among retailers, we sold our Wal-Mart position
     before the stock fell hard, investing in Target, Kohl's and Ross Stores. In
     addition, we increased the emphasis on financial services stocks, focusing
     on insurance companies with excellent valuations that were not as
     vulnerable to interest-rate increases as banks and other lenders. We
     continued to de-emphasize consumer staples, although we added Altria (the
     former Philip Morris), which offered a high dividend yield and an
     attractive stock price that we believed was the result of overly
     pessimistic market evaluations of the company's tobacco liability. In
     addition, we invested in First Data, the leader in processing of credit
     card transactions and owner of the Western Union system, and Accenture, an
     information-technology services consulting firm.

Q:   What were some of the investments that influenced performance?

A:   Among newer holdings, Macrovision rose significantly during the period as
     its revenue grew faster than had been expected. Sepracor, a pharmaceutical
     company and a new holding, also advanced on positive news of a drug under
     development. Zimmer Holdings, a world leader in orthopedic products,
     including hip and knee replacements, was another health-care position that
     did very well. The timely sale of Wal-Mart Stores also supported
     performance. The overweight position in the semiconductor industry early in
     the six-month



                                      D-28



     period held back performance, as valuations in that group fell hard.
     Corinthian Colleges, operator of adult vocational educational colleges and
     programs, was another detractor, as the SEC began an investigation of its
     financial records. However, we took advantage of the price decline to add
     to the position in Corinthian because of its good long-term fundamentals.
     Lexar and Sandisk, two manufacturers of flash memories for cameras and cell
     phones, also fell on disappointing sales. Freeport-McMoRan, a leader in the
     copper mining industry and a strong support for performance in 2003, also
     declined both because of problems at one of its mines and because of fears
     of an economic slowdown in China, an important importer of copper. We
     increased our investment in the company because of its attractive price. We
     also believed it experienced some short-term production problems that would
     be resolved.

Q:   What is your investment outlook?

A:   We are cautious about the near-term opportunities in the domestic stock
     market, as stock valuations appear relatively expensive and the Federal
     Reserve Board has moved to a less accommodating monetary policy. The home
     refinancing boom of the past two years may hurt the future earnings of
     banks, while the technology industry faces a number of challenges, from
     pricing pressure on its products to calls to change the way many companies
     have treated stock options in their accounting. Health care stocks,
     however, appear to be more reasonably valued. Given this outlook, we are
     paying very strict attention to our analysis and selection of individual
     companies. We also have somewhat reduced our exposure to the domestic stock
     market with investments in Europe and the emerging markets. We have, for

Portfolio Management's Discussion 3/31/04

     The stock market continued to rise through the final quarter of 2003 and
into this year, then took a modest breather late in this year's first quarter.
The period favored the Fund's value discipline, as value stocks in general
outperformed their growth counterparts. In the following discussion, portfolio
manager Rod Wright describes those events and the decisions that affected
Pioneer Value Fund's performance over the last six months.

Q:   Please describe the investment background over the last six months.

A:   As the economic recovery gathered strength, investors were encouraged by
     the increase being reported in corporate profits. Fueling the recovery in
     large measure were the lowest short-term interest rates in over 40 years
     and broad federal income tax cuts that put added cash into the hands of
     individuals and businesses. However, the markets stalled in March, as
     unemployment remained stubbornly high despite the continued economic
     expansion. Renewed geopolitical concerns and a dip in consumer confidence
     added to market uncertainty. Consumers account for more than half of US
     economic activity, and any pullback in their spending is taken as a
     negative sign.

Q:   How did Pioneer Value Fund perform against that background?

A:   For the six months ended March 31, 2004, Pioneer Value Fund's Class A, B, C
     and R shares had total returns at net asset value of 15.98%, 15.30%, 15.27%
     and 15.82%, respectively. In comparison, the Russell 1000 Value Index, the
     Fund's benchmark, returned 17.65% for the same period. The Fund's Lipper
     Large-Cap Value peers returned 15.94% for the six months ended March 31,
     2004.

Q:   Which of your decisions or strategies had the most impact on performance?

A:   Stock selection was generally favorable over this period, but sector
     emphasis hurt results, accounting for the Fund's relative underperformance
     versus the benchmark. In particular, we were underweight compared to our
     benchmark in financial stocks, a decision based on our expectation that
     interest rates would begin to rise and put pressure on the earnings of
     financial companies. But rates stayed low, and financials were one of the
     market's better-performing sectors over this period. A number of mergers
     within the industry also pushed up prices. In addition, the stronger
     economy had a positive impact on credit quality, favoring lending
     institutions. Countrywide Financial, a mortgage lender, was the Fund's
     biggest gainer among financial issues. Countrywide rose on news of
     surprisingly strong earnings as mortgage rates remained low and home
     refinancings continued. Citigroup, the Fund's largest holding, also rose
     during the period.

Q:   What other decisions or strategies had an impact on performance?

A:   Our overweight commitment to energy stocks aided results, as rising oil
     prices boosted their profit outlook. Successful stock selection added to
     the Fund's strong performance in this sector. Suncor Energy, which extracts
     oil from oil-bearing sands by means of a costly process, benefited when oil
     prices reached levels that allowed for profitable operations. Transocean
     Inc., a leading offshore drilling company, also saw increased activity as
     oil prices moved higher. Utilities companies generally added to Fund
     results, but Dominion Resources underperformed. Results benefited from good
     stock selection in the telecommunications sector, an area in which we
     maintained a neutral weighting compared to the benchmark. AT&T Wireless was
     a standout performer, rising sharply when news broke of its pending
     acquisition by Cingular. In technology, Motorola rose when operating
     results improved for the first time in three years. Strategic steps by
     Motorola's new management, including sale of the company's semiconductor
     unit, also benefited results. Tyco International, a diversified industrial
     company, rose as disciplined new management distanced the company from
     earlier problems, eliminated some non-essential business units and
     strengthened the firm's balance sheet by cutting outstanding debt. Another
     industrial company, Waste Management, rose on the basis of a successful
     turnaround. Management cut costs and upgraded systems while successfully
     integrating a number of acquisitions. The growing economy also boosted
     results, as waste volumes are tied to the level of business activity.

     In healthcare, Wellpoint Health Networks, a leading managed-care company,
     rose on the basis of earnings increases, increased market share and the
     imposition of higher premiums. Wellpoint has also agreed to merge with
     Anthem, another major health benefits company. In a related area, our
     overweight position in Merck hurt results; large pharmaceutical companies
     were laggards over the period.

Q:   Which of the Fund's other holdings held back results?

A:   Shares of Freddie Mac (The Federal Home Loan Mortgage Corporation), an
     issuer of mortgage-backed securities, declined. Shares weakened when
     questions arose about its method of calculating earnings, raising the
     possibility of more stringent regulation and greater government involvement
     with its operations. Among industrial issues, the rising price of oil
     pulled down the Fund's transportation stocks.



                                      D-31



     In addition, Southwest Airlines was hurt by an unresolved contract dispute
     with flight attendants. Donaldson Co., which manufactures filtration
     systems, declined following a disappointing earnings report.

Q:   What is your outlook for the economy and for value stocks?

A:   We believe the economy will continue expanding in the months ahead.
     However, some of the good economic news we anticipate may already be
     reflected in stock prices. In addition, if the expansion begins to generate
     inflationary forces in the economy, the Federal Reserve Board is likely to
     raise interest rates, a move that would dampen investor enthusiasm.
     Nevertheless, we are still finding good values, and with corporate
     fundamentals strong and improving, we expect good returns on equities for
     the balance of this year.

Portfolio Management Discussion 4/30/04

     Stock prices continued to climb during the six months ended April 30, 2004,
although new worries about the direction of interest rate moves, and concerns
about instability in Iraq, added to the volatility of the market. In the
following discussion, Rod Wright, leader of the team that manages Pioneer Mid
Cap Value Fund, provides an update on the Fund, its investment strategies and
the economic environment during the six-month period.

Q:   How did the Fund perform?

A:   The Fund did very well during a period of changing sentiment in the market.
     The Fund's Class A shares had a total return of 9.37% for the six months
     ended April 30, 2004, while Class B and Class C shares returned 8.89% and
     8.85%, respectively, all at net asset value. During the same period, the
     Standard & Poor's 500 Index, a benchmark for large-cap stocks, rose by
     6.27%, while the Russell Midcap Value Index gained 8.30%.

Q:   How would you characterize the market during the six months?

A:   It was a period of volatility and shifting trends. During the first two
     months of the period -- the final two months of 2003 -- we saw a
     continuation of the pattern that had characterized much of the year. As
     optimism grew that the economy was finally emerging from its slump and that
     corporate profits would continue to increase, stock prices rose, led by
     lower quality companies with weaker balance sheets. Technology stocks
     typically were among the performance leaders. That pattern began to change
     and the market became more volatile in the early weeks of 2004, amid
     worries that interest rates were beginning to rise and that the situation
     in Iraq was more troublesome than earlier believed. Interest rates did rise
     substantially from the middle of March through the end of April, which
     undermined the valuations of many technology companies, as well as the
     stocks in sectors particularly sensitive to changes in interest rates, such
     as financial services and utilities. Fortunately, the Fund was well
     positioned for this change in the direction of interest rates. Our
     underweight positions among financial and utility companies helped
     performance, as did our de-emphasis of technology companies.

Q:   What types of investments tended to help performance?

A:   Our strategy emphasizes fundamental analysis of companies and individual
     stock-picking, rather than major sector decisions based on macroeconomic
     trends. We seek good companies at attractive valuations, irrespective of
     their industry. The biggest single contributor to performance was sports
     retailer Foot Locker, a major holding, which posted strong earnings gains
     during the period. But we also enjoyed excellent results from our
     selections in the healthcare and energy sectors. In the health-care sector,
     top performers included medical-supply company Becton, Dickinson, and
     dental-supply company Apogent Technologies, which received a takeover offer
     during the period.

     Our investment in Wellpoint Health Networks, an HMO, also appreciated
     sharply as it merged with Anthem. In the energy sector, top performers
     included Transocean, a deepwater drilling company, and Occidental
     Petroleum, a fully integrated energy corporation. While the stock prices of
     many technology companies discouraged us from investing, we did have some
     excellent results in the sector, including NCR, a hardware and systems
     company, and Autodesk, a software firm. We also enjoyed excellent results
     from ConAgra, an agricultural products and food-processing firm, and
     Republic Services, a waste-disposal corporation.

Q:   What types of investments were disappointing during the period?

A:   Basic materials companies, which had supported the Fund's performance
     during 2003, tended to detract from results as interest rates began to
     rise. A good example was mining company Freeport-McMoRan, which we have
     eliminated from the portfolio. Securities transaction processor Investment
     Technology Group declined when its trading volumes declined, while toy
     maker Mattel fell when analysts began doubting the continued strength of
     the Barbie line.

Q:   What is your investment outlook?

A:   We continue to be encouraged by the strong economy and the inexpensive
     dollar, which helps domestic companies compete globally. While interest
     rates have started to increase and the Federal Reserve is expected to raise
     short-term rates this year, rates are likely to remain relatively low when
     compared to historical standards. However, the stock market has enjoyed an
     extraordinary rally since March 2003, and many companies already are
     selling at high valuations based on anticipations of strong future earnings
     growth. As a result, while we are optimistic about the economy, we are more
     guarded about opportunities in the overall market, and we will continue to
     emphasize strong companies with attractive stock valuations.

Portfolio Management's Discussion 5/31/04

     A shift by investors away from speculative issues into higher quality,
small-capitalization stocks helped Pioneer Small Cap Value Fund outperform its
benchmark index over the past six months. In the following discussion, portfolio
manager David Adams and assistant portfolio manager Jack McPherson review their
investment strategies and the factors that led to these favorable results.

Q:   What were market conditions like over this period and how did you respond?

A.   Strong growth in the last quarter of 2003 extended into this year as a
     broad-based economic recovery continued to take shape. At the same time,
     increased global demand pushed up prices for most commodities, triggering
     inflation concerns and increasing the possibility that the Federal Reserve
     Board will raise interest rates over the summer.

     We were rewarded over this period for staying with our long established
     investment discipline. Late in 2003, the Fund's results, although positive,
     nevertheless lagged the benchmark because we do not invest in the kinds of
     high-risk issues that were market leaders at the time. More recently,
     better quality issues that fit our criteria for valuation, financial
     strength and earnings potential have attracted the market's attention. By
     the end of the period, Fund performance had swung from trailing the
     benchmark because of stocks we did not own, to outperforming our benchmark
     thanks to successful stock selection.

Q:   Given that background, how did the Fund perform?

A.   For the six-month period ended May 31, 2004, Pioneer Small Cap Value Fund's
     Class A, B, C and R shares returned 9.59%, 9.13% 9.09% and 9.59%
     respectively, all at net asset value. These results outdistanced the 6.32%
     return of the Russell 2000 Value Index, the Fund's benchmark, for the same
     period.

Q:   Which of your decisions aided Fund performance?

A.   In our bottom-up process, our stock choices produce the portfolio's sector
     weightings. A shortage of attractive values and the possibility of higher
     interest rates left the portfolio underweighted in financial services
     companies compared to the benchmark. That stance helped performance, as
     many financial issues were poor performers. Also beneficial was our
     decision to downplay companies that are most vulnerable to higher rates --
     thrifts that rely heavily on mortgage financing, and real estate investment
     trusts. Instead, we emphasized commercial banks that can gain earning power
     as economic activity pushes rates higher just when businesses are
     increasing their borrowing. We took profits in Irwin

     Financial, which has a large mortgage lending subsidiary. Texas Capital
     Bancshares and Virginia-based Cardinal Financial both are expected to
     benefit from the fallout of the merger activity taking place among the
     larger national banking companies, as well as the improving business
     environment for their small- and mid-size business customers.

     Overweighting and successful selection of energy stocks aided results as
     investors took notice of attractive valuations. Coal producer Massey Energy
     was the Fund's most successful holding over this period. Global energy
     demand drove up the price of Appalachian coal. In addition, as the US
     dollar weakened, the price of US coal fell in terms of foreign currencies,
     making the price of our coal competitive in world markets for the first
     time in years. Southwestern Energy, Penn Virginia and Swift Energy also
     moved higher.

Q:   What other sectors or stocks had an impact, for better or worse?

A.   Our slightly overweight position in transportation stocks led to positive
     results that ran contrary to the industrials sector's trend. Stelmar
     Shipping, based in Greece, continues to benefit as available tanker
     capacity lags behind the demands of a growing world economy and not enough
     new ships are being built. In addition, a high percentage of Stelmar's
     fleet already meets the mandate for double-hulled ships, allowing it to
     charge premium rates. Genesee & Wyoming, which acquires and operates short
     line railroads in North America and Australia, saw a pickup in demand for
     hauling iron ore and coal as well as large harvests of grain in Australia.
     Genesee also has lower labor costs than some large railroads. We bought
     Wabtec, which makes components parts for railcars, at a low point in its
     business cycle. Shares moved higher when industrial growth began to absorb
     the oversupply of railcars and orders for new cars came in. Pediatrix
     Medical Group, which runs specialized neonatology practices in hospitals,
     continued to deliver good results, as did Pacificare Health Systems, a
     leading Medicare HMO. Chattem, marketer of Gold Bond, Icy Hot and other
     consumer healthcare brands, rebounded sharply after resolving pending
     litigation. In commercial services, our patience with Central Parking was
     rewarded as the better economic environment and the return of the company
     founder in the role of CEO has begun to have a positive impact on their
     business. But PRG Schultz, which provides specialized auditing services,
     continued to wrestle with merger related problems. Technology, where our
     relatively small exposure hurt results, was also a disappointment. Remec, a
     maker of microwave and other wireless transmission equipment, ran afoul of
     internal problems and is undergoing a management shakeup. We believe
     Remec's core business is solid and that a new management team enhances its
     outlook. Shares of software maker SPSS fell back, while Borland Software
     continued to



                                      D-36



     tread water. Insight Enterprises, a distributor of computers and
     peripherals to mid-sized businesses, slipped back slightly following a very
     strong run late last year and into the beginning of this year. We think
     Insight remains an attractive way to capitalize on possible increases in
     corporate technology spending. Insituform's sewer maintenance business
     continued to feel the constraints of tight municipal budgets. Our
     performance among insurance stocks trailed the benchmark.

Q:   What is your outlook for the next several months?

A.   The economic recovery has by now benefited most sectors of the market. But
     it is not yet clear whether the expansion is merely satisfying pent-up
     demand or we are at the beginning of a sustained period of growth. High
     prices for industrial and other commodities give pause, as inflation
     remains a threat to the recovery. The upcoming presidential election and
     geopolitical tensions may also have unforeseeable market impacts.
     Nevertheless, we continue to find good companies that seem mispriced in the
     marketplace, given their potential for earnings expansion over the next two
     or three years.

(a)       No adjustments are shown to the unaudited pro forma combined schedule
          of investments due to the fact that upon consummation of the merger,
          no securities would need to be sold in order for Pioneer Balanced Fund
          to comply with its prospectus restrictions. The foregoing sentence
          shall not restrict in any way the ability of the investment adviser of
          either of the funds from buying or selling securities in the normal
          course of such fund's business and operations.

          Securities Act of 1933. Such securities may be resold normally to
          qualified institutional buyers in a transaction exempt from
          Registration. At December 31, 2003, the value of these securities
          amounted to $2,795,360 or 1.8% of total net assets.

          basis with an approximate (generally plus or minus 2.5%) principal
          amount and no definite maturity date period. The actual principal

Pioneer Balanced Fund
NOTES TO PRO FORMA COMBINED FINANCIAL STATEMENTS
12/31/03

(Unaudited)

NOTES TO FINANCIAL STATEMENTS 12/31/03

    1.   General

The accompanying pro forma combined financial statements are presented to show
the effect of the proposed acquisition (the "acquisition") of Safeco Balanced
Fund by Pioneer Balanced Fund.

Under the terms of an Agreement and Plan of Reorganization between the Funds,
the combination of Pioneer Balanced Fund and Safeco Balanced Fund will be
treated as a tax-free business combination and accordingly will be accounted for
by a method of accounting for tax-free mergers of investment companies. The
acquisition will be accomplished by an acquisition of the net assets of Safeco
Balanced Fund in exchange for a new "Investor Class" of shares of Pioneer
Balanced Fund at net asset value, which will be established upon consummation of
the merger. The accompanying schedules of investments, statements of assets and
liabilities and the related statements of operations of Pioneer Balanced Fund
and Safeco Balanced Fund have been combined as of and for their most recent
fiscal year ended December 31, 2003. Adjustments have been made to expenses for
duplicate services that would not have been incurred if the merger took place on
January 1, 2003. Following the acquisition, the Pioneer Balanced Fund will be
the accounting survivor. All related acquisition costs will be borne by the
Advisors.

These pro forma financial statements and related notes should be read in
conjunction with the financial statements of Pioneer Balanced Fund and Safeco
Balanced Fund included in their respective annual reports dated December 31,
2003.

    2.   Organization and Significant Accounting Policies

Pioneer Balanced Fund (the Fund) is a Delaware statutory trust registered under
the Investment Company Act of 1940 as a diversified, open-end management
investment company. The Fund's investment objective is to seek capital growth
and current income.

After the merger, the Fund will consist of four classes of shares - Class A,
Class B, Class C and Investor Class shares. Investor Class shares are only being
offered as part of the acquisition and will not be available following the
merger. Each class of shares represent an interest in the same portfolio of
investments of the Fund and have equal rights to voting, redemptions, dividends
and liquidation, except that each class of shares can bear different transfer
agent and distribution fees and has exclusive voting rights with respect to the
distribution plans that have been adopted by Class A, Class B and Class C,
respectively. There is no distribution plan for Investor Class shares.

Each Fund's management has prepared their respective financial information using
estimates and assumptions that affect the reported amounts of assets and
liabilities, the disclosure of contingent assets and liabilities at the date of
the pro forma financial statements, and the reported amounts of income, expenses
and gains and losses on investments during the reporting periods. Actual results
could differ from those estimates.

The following is a summary of significant accounting policies consistently
followed by the Fund, which are in conformity with those generally accepted in
the investment company industry:

                                      -31-


    A.   Security Valuation

Security transactions are recorded as of trade date. The net asset value is
computed once daily, on each day the New York Stock Exchange is open, as of the
close of regular trading on the Exchange. In computing the net asset value, debt
securities are valued at prices supplied by independent pricing services, which
consider such factors as Treasury spreads, yields, maturities and ratings.
Valuations may be supplemented by dealers and other sources, as required. Equity
securities are valued at the last sale price on the principal exchange where
they are traded. Securities that have not traded on the date of valuation, or
securities for which sale prices are not generally reported, are valued at the
mean between the last bid and asked prices. Securities for which market
quotations are not readily available are valued at their fair values as
determined by, or under the direction of, the Fund's Board of Trustees. At
December 31, 2003, there were no securities fair valued. Dividend income is
recorded on the ex-dividend date except that certain dividends from foreign
securities where the ex dividend date may have passed are recorded as soon as
the Fund becomes aware of the ex-dividend data in exercise of reasonable
diligence. Interest income is recorded on the accrual basis. All
discounts/premiums on debt securities are accreted/amortized into interest
income for financial reporting purposes. Temporary cash investments are valued
at amortized cost.

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

    B.   Futures Contracts

The Fund may enter into futures transactions to hedge against changes in
interest rates, securities prices, and currency rates or to seek to increase
total return. Upon entering into a futures contract, the Fund is required to
deposit with a broker an amount of cash or securities equal to the minimum
"initial margin" requirements of the associated futures exchange. Subsequent
payments on futures contracts ("variation margin") are paid or received by the
Fund, depending on the daily fluctuation in the value of the contracts, and are
recorded by the Fund as unrealized gains or losses. When the contract is closed,
the Fund realizes a gain or loss equal to the difference between the opening and
closing value of the contract. The use of futures contracts involves, to varying
degrees, elements of market risk which may exceed the amounts recognized by the
Fund. Changes in the value of the contracts may not directly correlate to the
changes in the value of the underlying securities. These risks may decrease the
effectiveness of the Fund's hedging and trading strategies and potentially
result in a loss. As of December 31, 2003, the Fund had no open futures
contracts.

    C.   Federal Income Taxes

Each fund has previously elected to be taxed as a "regulated investment company"
under the Internal Revenue Code. After the acquisition, it will 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 combined capital loss carryforward of $14,612,000 includes a net capital
loss carryforward of $1,101,000 from the merger with Safeco Balanced Fund, the
full use of which may be limited.

    D.   Fund Shares

The Fund records sales and repurchases of its shares as of trade date. Pioneer
Funds Distributor, Inc. (PFD), the principal underwriter for the Fund and a
wholly owned subsidiary of UniCredito Italiano S.p.A. (UniCredito Italiano),
earned $20,585 in underwriting commissions on the sale of Fund shares during the
year ended of December 31, 2003.

                                      -32-


    E.   Class Allocations

Distribution fees are calculated based on the average daily net asset value
attributable to Class A, Class B, Class C, and Investor Class shares of the
Fund, respectively. Shareowners of each class share all expenses and fees paid
to the transfer agent, Pioneer Investment Management Shareholder Services, Inc.
(PIMSS), for its services, which are allocated based on the number of accounts
in each class and the ratable allocation of related out-of-pocket expenses (see
Note 5). Income, common expenses and realized and unrealized gains and losses
are calculated at the Fund level and allocated daily to each class of shares
based on the respective percentage of adjusted net assets at the beginning of
the day. Distributions to shareowners are recorded as of the ex-dividend date.
Distributions paid by the Fund with respect to each class of shares are
calculated in the same manner, at the same time, and in the same amount, except
that Class A, Class B, Class C, and Investor Class shares can bear different
transfer agent and distribution fees.

    F.   Securities Lending

The Fund lends securities in its portfolio to certain broker-dealers or other
institutional investors, with the Fund's custodian acting as the lending agent.
When entering into a loan, the Fund receives collateral which is maintained by
the custodian and earns income in the form of negotiated lenders' fees. The Fund
also continues to receive interest or dividends on the securities loaned. Gain
or loss on the fair value of the loaned securities that may occur during the
term of the loan will be for the account of the Fund. The loans are secured by
collateral of at least 102%, at all times, of the fair value of the securities
loaned. The amount of the collateral will be adjusted daily to reflect any price
fluctuation in the value of the loaned securities. The Fund has the right under
the lending agreements to recover the securities from the borrower on demand.
The Fund invests cash collateral in temporary cash investments.

    G.   Repurchase Agreements

With respect to repurchase agreements entered into by the Fund, the value of the
underlying securities (collateral), including accrued interest received from
counterparties, is required to be at least equal to or in excess of the value of
the repurchase agreement at the time of purchase. The collateral for all
repurchase agreements is held in safekeeping in the customer-only account of the
Fund's custodian, or sub-custodians. The Fund's investment adviser, Pioneer
Investment Management, Inc. (PIM), is responsible for determining that the value
of the collateral remains at least equal to the repurchase price.

    3.   Capital Shares

The pro forma net asset value per share assumes the issuance of shares of the
Fund that would have been issued at December 31, 2003, in connection with the
proposed acquisition. The number of the shares assumed to be issued is equal to
the net asset value of Safeco Balanced Fund, as of December 31, 2003, divided by
the net asset value per share of the Investor Class shares of the Fund as of
December 31, 2003. The pro forma number of shares outstanding (in thousands), by
class, for the combined fund consist of the following at December 31, 2003:



                        Shares of       Additional Shares    Total Outstanding
                        the Fund         Assumed Issued           Shares
Class of Shares      Pre-Combination    In Reorganization    Post-Combination
- ---------------      ---------------    -----------------    -----------------
                                                             
Class A                     11,326                                    11,326
Class B                      1,725                                     1,725
Class C                        891                                       891
Investor Class                   -                2,129                2,129


4.       Management Agreement

                                      -33-


PIM manages the Fund's portfolio and is a wholly owned indirect subsidiary of
UniCredito Italiano. Management fees are calculated daily at the annual rate of
0.65% of the Fund's average daily net assets up to $1 billion; 0.60% of the next
$4 billion; and 0.55% of the excess over $5 billion.

In addition, under the management and administration agreements, certain other
services and costs, including accounting, regulatory reporting and insurance
premiums, are paid by the Fund. At December 31, 2003, $95,742 was payable to PIM
related to management fees, administrative fees and certain other services, and
is included in due to affiliates.

5.       Transfer Agent

PIMSS, a wholly owned subsidiary of UniCredito Italiano, provides substantially
all transfer agent and shareowner services to the Fund at negotiated rates.
Included in due to affiliates is $39,145 in transfer agent fees payable to PIMSS
at December 31, 2003.

6.       Distribution Plans

The Fund adopted a Plan of Distribution for each class of shares (Class A Plan,
Class B Plan and Class C Plan) in accordance with Rule 12b-1 of the Investment
Company Act of 1940. Pursuant to the Class A Plan, the Fund pays PFD a service
fee of up to 0.25% of the average daily net assets attributable to Class A
shares in reimbursement of its actual expenditures to finance activities
primarily intended to result in the sale of Class A shares. Pursuant to the
Class B Plan and the Class C Plan, the Fund pays PFD 1.00% of the average daily
net assets attributable to each class of shares. The fee consists of a 0.25%
service fee and a 0.75% distribution fee paid as compensation for personal
services and/or account maintenance services or distribution services with
regard to Class B and Class C shares. Included in due to affiliates is $48,095
in distribution fees payable to PFD at December 31, 2003.

In addition, redemptions of each class of shares (except Investor Class shares)
may be subject to a contingent deferred sales charge (CDSC). A CDSC of 1.00% may
be imposed on redemptions of certain net asset value purchases of Class A shares
within one year of purchase. Class B shares that are redeemed within six years
of purchase are subject to a CDSC at declining rates beginning at 4.00%, based
on the lower of cost or market value of shares being redeemed. Redemptions of
Class C shares within one year of purchase are subject to a CDSC of 1.00%.
Proceeds from the CDSCs are paid to PFD. For the year ended December 31, 2003,
CDSCs in the amount of $45,031 were paid to PFD.

Investor Class shares will not be subject to shareholder servicing or
distribution fees. Investor Class shares will be converted to Class A shares 24
months after the date on which the acquisition is completed.

7.       Expense Offset Arrangements

The Fund has entered into certain expense offset arrangements with PIMSS
resulting in a reduction in the Fund's total expenses due to interest earned on
cash held by PIMSS. For the year ended December 31, 2003, the Fund's expenses
were reduced by $4,000 under such arrangements.

8.       Line of Credit Facility

The Fund, along with certain others in the Pioneer Family of Funds (the Funds),
collectively participate in a $50 million committed, unsecured revolving line of
credit facility. Borrowings are used solely for temporary or emergency purposes.
The Fund may borrow up to the lesser of $50 million or the limits set by its
prospectus for borrowings. Interest on collective borrowings is payable at the
Federal Funds Rate plus 1/2% on an annualized basis. The Funds pay an annual
commitment fee for this facility. The commitment fee is allocated among such
Funds based on their respective borrowing limits. For the year ended December
31, 2003, the Fund had no borrowings under this agreement.

Pioneer Balanced Fund
NOTES TO PRO FORMA COMBINED FINANCIAL STATEMENTS
6/30/04

(Unaudited)

1.       General

The accompanying pro forma combined financial statements are presented to show
the effect of the proposed acquisition (the "acquisition") of Safeco Balanced
Fund by Pioneer Balanced Fund.

Under the terms of an Agreement and Plan of Reorganization between the Funds,
the combination of Pioneer Balanced Fund and Safeco Balanced Fund will be
treated as a tax-free business combination and accordingly will be accounted for
by a method of accounting for tax-free mergers of investment companies. The
acquisition will be accomplished by an acquisition of the net assets of Safeco
Balanced Fund in exchange for a new "Investor Class" of shares of Pioneer
Balanced Fund at net asset value, which will be established upon consummation of
the merger. The accompanying schedules of investments, statements of assets and
liabilities and the related statements of operations of Pioneer Balanced Fund
and Safeco Balanced Fund have been combined as of and for their most recent 12
months ended June 30, 2004. Adjustments have been made to expenses for duplicate
services that would not have been incurred if the merger took place on July 1,
2003. Following the acquisition, the Pioneer Balanced Fund will be the
accounting survivor. All related acquisition costs will be borne by the
Advisors.

These pro forma financial statements and related notes should be read in
conjunction with the financial statements of Pioneer Balanced Fund and Safeco
Balanced Fund included in their respective semiannual reports dated June 30,
2004.

2.       Organization and Significant Accounting Policies

Pioneer Balanced Fund (the Fund) is a Delaware statutory trust registered under
the Investment Company Act of 1940 as a diversified, open-end management
investment company. The Fund's investment objective is to seek capital growth
and current income.

After the merger, the Fund will consist of four classes of shares - Class A,
Class B, Class C and Investor Class shares. Investor Class shares are only being
offered only as part of the acquisition and will not be available following the
merger. Each class of shares represent an interest in the same portfolio of
investments of the Fund and have equal rights to voting, redemptions, dividends
and liquidation, except that each class of shares can bear different transfer
agent and distribution fees and has exclusive voting rights with respect to the
distribution plans that have been adopted by Class A, Class B and Class C,
respectively. There is no distribution plan for Investor Class shares.

Each Fund's management has prepared their respective financial information using
estimates and assumptions that affect the reported amounts of assets and
liabilities, the disclosure of contingent assets and liabilities at the date of
the pro forma financial statements, and the reported amounts of income, expenses
and gains and losses on investments during the reporting periods. Actual results
could differ from those estimates.

The following is a summary of significant accounting policies consistently
followed by the Fund, which are in conformity with those generally accepted in
the investment company industry:

A.       Security Valuation

Security transactions are recorded as of trade date. The net asset value is
computed once daily, on each day the New York Stock Exchange is open, as of the
close of regular trading on the Exchange. In computing the net asset value, debt
securities are valued at prices supplied by independent pricing services, which

                                      -54-


consider such factors as Treasury spreads, yields, maturities and ratings. All
discounts/premiums on debt securities are accreted/amortized into interest
income for financial reporting purposes. Valuations may be supplemented by
dealers and other sources, as required. Equity securities are valued at the last
sale price on the principal exchange where they are traded. Securities that have
not traded on the date of valuation, or securities for which sale prices are not
generally reported, are valued at the mean between the last bid and asked
prices. Securities for which market quotations are not readily available are
valued at their fair values as determined by, or under the direction of, the
Fund's Board of Trustees. At June 30, 2004, there were no securities fair
valued. Dividend income is recorded on the ex-dividend date except that certain
dividends from foreign securities where the ex dividend date may have passed are
recorded as soon as the Fund becomes aware of the ex-dividend data in exercise
of reasonable diligence. Interest income is recorded on the accrual basis.
Temporary cash investments are valued at amortized cost.

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

B.       Futures Contracts

The Fund may enter into futures transactions to hedge against changes in
interest rates, securities prices, and currency rates or to seek to increase
total return. Upon entering into a futures contract, the Fund is required to
deposit with a broker an amount of cash or securities equal to the minimum
"initial margin" requirements of the associated futures exchange. Subsequent
payments on futures contracts ("variation margin") are paid or received by the
Fund, depending on the daily fluctuation in the value of the contracts, and are
recorded by the Fund as unrealized gains or losses. When the contract is closed,
the Fund realizes a gain or loss equal to the difference between the opening and
closing value of the contract. The use of futures contracts involves, to varying
degrees, elements of market risk which may exceed the amounts recognized by the
Fund. Changes in the value of the contracts may not directly correlate to the
changes in the value of the underlying securities. These risks may decrease the
effectiveness of the Fund's hedging and trading strategies and potentially
result in a loss. As of June 30, 2004, the Fund had no open futures contracts.

C.       Federal Income Taxes

Each Fund has previously elected to be taxed as a "regulated investment company"
under the Internal revenue Code. After the acquisition, it will 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.

At December 31, 2003, the combined capital loss carryforward of $14,612,000
includes a net capital loss carryforward of $1,101,000 from the merger with
Safeco Balanced Fund, the full use of which may be limited.

D.       Fund Shares

The Fund records sales and repurchases of its shares as of trade date. Pioneer
Funds Distributor, Inc. (PFD), the principal underwriter for the Fund and a
wholly owned subsidiary of UniCredito Italiano S.p.A. (UniCredito Italiano),
earned $24,469 in underwriting commissions on the sale of Fund shares during the
12 months ended June 30, 2004.

E.       Class Allocations

Distribution fees are calculated based on the average daily net asset value
attributable to Class A, Class B, Class C, and Investor Class shares of the
Fund, respectively. Shareowners of each class share all expenses and fees paid
to the transfer agent, Pioneer Investment Management Shareholder Services, Inc.
(PIMSS), for its services, which are allocated based on the number of accounts
in each class and the ratable allocation

                                      -55-


of related out-of-pocket expenses (see Note 5). Income, common expenses and
realized and unrealized gains and losses are calculated at the Fund level and
allocated daily to each class of shares based on the respective percentage of
adjusted net assets at the beginning of the day. Distributions to shareowners
are recorded as of the ex-dividend date. Distributions paid by the Fund with
respect to each class of shares are calculated in the same manner, at the same
time, and in the same amount, except that Class A, Class B, Class C, and
Investor Class shares can bear different transfer agent and distribution fees.

F.       Securities Lending

The Fund lends securities in its portfolio to certain broker-dealers or other
institutional investors, with the Fund's custodian acting as the lending agent.
When entering into a loan, the Fund receives collateral which is maintained by
the custodian and earns income in the form of negotiated lenders' fees. The Fund
also continues to receive interest or dividends on the securities loaned. Gain
or loss on the fair value of the loaned securities that may occur during the
term of the loan will be for the account of the Fund. The loans are secured by
collateral of at least 102%, at all times, of the fair value of the securities
loaned. The amount of the collateral will be adjusted daily to reflect any price
fluctuation in the value of the loaned securities. The Fund has the right under
the lending agreements to recover the securities from the borrower on demand.
The Fund invests cash collateral in temporary cash investments.

G.       Repurchase Agreements

With respect to repurchase agreements entered into by the Fund, the value of the
underlying securities (collateral), including accrued interest received from
counterparties, is required to be at least equal to or in excess of the value of
the repurchase agreement at the time of purchase. The collateral for all
repurchase agreements is held in safekeeping in the customer-only account of the
Fund's custodian, or sub-custodians. The Fund's investment adviser, Pioneer
Investment Management, Inc. (PIM), is responsible for determining that the value
of the collateral remains at least equal to the repurchase price.

3.       Capital Shares

The pro forma net asset value per share assumes the issuance of shares of the
Fund that would have been issued at June 30, 2004, in connection with the
proposed acquisition. The number of the shares assumed to be issued is equal to
the net asset value of Safeco Balanced Fund, as of June 30, 2004, divided by the
net asset value per share of the Investor Class shares of the Fund as of June
30, 2004. The pro forma number of shares outstanding (in thousands), by class,
for the combined fund consist of the following at June 30, 2004:



                        Shares of       Additional Shares    Total Outstanding
                        The Fund         Assumed Issued           Shares
  Class of Shares    Pre-Combination    In Reorganization    Post-Combination
  ---------------    ---------------    -----------------    ----------------

Class B                      1,950                                     1,950
Class C                      1,023                                     1,023
Investor Class                   -                2,033                2,033


4.       Management Agreement

PIM manages the Fund's portfolio and is a wholly owned indirect subsidiary of
UniCredito Italiano. Management fees are calculated daily at the annual rate of
0.65% of the Fund's average daily net assets up to $1 billion; 0.60% of the next
$4 billion; and 0.55% of the excess over $5 billion.

In addition, under the management and administration agreements, certain other
services and costs, including accounting, regulatory reporting and insurance
premiums, are paid by the Fund. At June 30,

                                      -56-


2004, $92,488 was payable to PIM related to management fees, administrative fees
and certain other services, and is included in due to affiliates.

5.       Transfer Agent

PIMSS, a wholly owned subsidiary of UniCredito Italiano, provides substantially
all transfer agent and shareowner services to the Fund at negotiated rates.
Included in due to affiliates is $51,300 in transfer agent fees payable to PIMSS
at June 30, 2004.

6.       Distribution Plans

The Fund adopted a Plan of Distribution for each class of shares (Class A Plan,
Class B Plan and Class C Plan) in accordance with Rule 12b-1 of the Investment
Company Act of 1940. Pursuant to the Class A Plan, the Fund pays PFD a service
fee of up to 0.25% of the average daily net assets attributable to Class A
shares in reimbursement of its actual expenditures to finance activities
primarily intended to result in the sale of Class A shares. Pursuant to the
Class B Plan and the Class C Plan, the Fund pays PFD 1.00% of the average daily
net assets attributable to each class of shares. The fee consists of a 0.25%
service fee and a 0.75% distribution fee paid as compensation for personal
services and/or account maintenance services or distribution services with
regard to Class B and Class C shares. Included in due to affiliates is $50,005
in distribution fees payable to PFD at June 30, 2004.

In addition, redemptions of each class of shares (except Investor Class shares)
may be subject to a contingent deferred sales charge (CDSC). A CDSC of 1.00% may
be imposed on redemptions of certain net asset value purchases of Class A shares
within one year of purchase. Class B shares that are redeemed within six years
of purchase are subject to a CDSC at declining rates beginning at 4.00%, based
on the lower of cost or market value of shares being redeemed. Redemptions of
Class C shares within one year of purchase are subject to a CDSC of 1.00%.
Proceeds from the CDSCs are paid to PFD. For the 12 months ended June 30, 2004,
CDSCs in the amount of $62,806 were paid to PFD.

Investor Class shares will not be subject to shareholder servicing or
distribution fees. Investor Class shares will be converted to Class A shares 24
months after the date on which the acquisition is completed.

7.       Expense Offset Arrangements

The Fund has entered into certain expense offset arrangements with PIMSS
resulting in a reduction in the Fund's total expenses due to interest earned on
cash held by PIMSS. For the 12 months ended June 30, 2004, the Fund's expenses
were reduced by $4,000 under such arrangements.

8.       Line of Credit Facility

The Fund, along with certain others in the Pioneer Family of Funds (the Funds),
collectively participate in a $50 million committed, unsecured revolving line of
credit facility. Borrowings are used solely for temporary or emergency purposes.
The Fund may borrow up to the lesser of $50 million or the limits set by its
prospectus for borrowings. Interest on collective borrowings is payable at the
Federal Funds Rate plus 1/2% on an annualized basis. The Funds pay an annual
commitment fee for this facility. The commitment fee is allocated among such
Funds based on their respective borrowing limits. For the 12 months ended June
30, 2004, the Fund had no borrowings under this agreement.
