LETTER TO SHAREOWNERS 6/30/04
- --------------------------------------------------------------------------------

Dear Shareowner,
- --------------------------------------------------------------------------------
U.S. equity markets traced a jagged course through the first half of the year,
ending on June 30 only slightly ahead of where they started. Mid-sized and
small-cap indices scored modest gains, while indicators that track large-cap
stocks showed even smaller changes. For bond investors, Treasury issues wound
up the period with higher yields and lower prices than at year-end. The same
was true of corporate issues, whose prices gave ground in the face of rising
interest rates, while high-yield bonds, outstanding performers over recent
quarters, also cooled off.

Although the economic expansion continued to move ahead, investors were
preoccupied with factors that might have undesirable impacts on the economy and
the markets. For one thing, the threat of terrorism is never far from our
minds. For another, the jump in oil prices, attributed to turmoil in the
Mideast and vast demand from China and other developing nations, was a major
factor. The cost of gas or oil for heating our homes, and gasoline for our cars
is a critical component in household budgets. Industry, too, requires energy,
and in many cases petroleum is an essential raw material.

The "jobless" recovery became a job-generating machine for a few months,
followed by a brief slump and a partial rebound. But strong boosts in
employment quickly triggered fears of economic overheating; too much demand for
goods and services, the reasons for aggressive corporate hiring, might trigger
inflation. That would lead to higher interest rates that could choke off the
recovery by causing consumers and businesses to hold back on outlays. In fact,
on June 30, the Federal Reserve Board raised short-term interest rates by
one-quarter percentage point, the first hike in four years.

While there may be further increases, they probably will be gradual; the
Federal Reserve Board would like to keep the expansion intact while keeping
inflation at bay. And even after the Fed's June move, short-term rates remain
near the lowest levels many of us have seen. U.S. businesses, which have done
massive amounts of cost-cutting in recent years, can readily accommodate
somewhat higher borrowing costs. In addition, the federal income tax cuts that
have helped bolster growth over the past several quarters remain in place.

The possibility of higher interest rates and the economy's direction could have
important implications for the way your portfolio is balanced, so an
appointment with your professional financial advisor may well be in order.

When you talk to your advisor, ask to hear about the Pioneer Oak Ridge and
Pioneer Papp Funds. These six additions to our product lineup are designed to
broaden your opportunities to pursue growth. Please consider the Funds'
investment objectives, risks, charges and expenses carefully before investing.
The prospectus contains that and other information about the Fund and should be
read carefully before you invest or send money. To obtain a prospectus and for
other information on any Pioneer fund, contact your investment advisor, call

PORTFOLIO MANAGEMENT DISCUSSION 6/30/04
- --------------------------------------------------------------------------------

As market interest rates spiked up in the final half of the 12-month period
ending June 30, 2004, high-yield corporate bonds and mortgage-backed securities
provided the best defensive protection, as conditions changed in the U.S.
fixed-income market. In the following discussion, Kenneth J. Taubes discusses
the factors that influenced Pioneer Bond Fund's performance during the 12
months. Mr. Taubes, Director of Pioneer's Fixed Income Group, oversees the team
responsible for daily management of the Fund.

Q:  How did the Fund perform during the 12 months ended June 30, 2004?

A:  In a challenging period for fixed-income investing, Pioneer Bond Fund
    outdistanced both market benchmarks and competitive peer group averages. For
    the 12 months, the Fund's Class A shares had a total return of 2.98%, while
    Class B and Class C shares returned 2.04% and 2.11%, respectively, all at
    net asset value. During the same 12 months, the Lehman Aggregate Bond Index
    had a return of 0.32%, while the average return of funds in Lipper's A-Rated
    Corporate Debt category was 0.04%. The Fund also continued to deliver a
    competitive yield. The standardized 30-day SEC yield on Class A shares on
    June 30, for example, was 4.30%.

Q:  What were the factors that affected performance?

A:  The Fund's performance was helped both by asset allocation and good security
    selection. We had the largest overweight positions in the two asset classes
    with the best performance during the 12 months: high-yield corporate bonds
    and mortgage-backed securities. Throughout the year, we kept the Fund's
    high-yield exposure close to the 20% limit of our policy. That strategy
    helped substantially as the high-yield market, as measured by the Merrill
    Lynch High Yield Master II Index, returned 10.30% for the 12 months. We also
    had more than 40% of assets invested in mortgage securities during a period
    in which mortgages were the best performing part of the investment-grade
    fixed-income market. As a result, typically 60% to 65% of Fund assets were
    invested in the two best performing parts of the bond market. Both
    high-yield bonds and mortgage-backed securities tend to be more resistant to
    the effects of price losses from increasing interest-rates than other bonds
    because of their yield advantages. The performance of

    mortgage-backed securities is also helped by the tendency of mortgage
    prepayment risk to decline as interest rates rise.

    We held our allocation to Treasury securities, the worst performing part of
    the bond market, to less than 10% of assets during the period, and focused
    our Treasury exposure on inflation-protected Treasuries, which outperformed
    standard Treasury securities. Treasuries were the worst performing part of
    the fixed-income market. During the 12-month period, the prices of 10-year
    Treasuries declined by 7.5%.

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

A:  Several high-yield corporate bonds made significant contributions to
    performance. Bonds issued by Corning, which restructured its business to
    focus on the production of the material used for flat-screen monitors, did
    very well, as did securities of retailer J.C. Penney, which improved its
    credit position through restructuring and the sale of its pharmacy chain
    division.

    Bonds issued by hotel chains also did well as the economy improved and
    business travel increased. Among the top performers in the portfolio were
    bonds issued by the Hilton, Starwood and John Q. Hammond hotel chains. The
    securities of insurance company Allmerica Financial also appreciated in
    price during the period as a result of that company's positive restructuring
    efforts.

Q:  How would you describe the Fund's overall positioning?

A:  We kept the Fund positioned to benefit from the improving economy, which
    helps support the corporate bond market, while guarding against the threat
    of rising interest rates.

    At the end of the fiscal year, on June 30, mortgage securities accounted for
    44.9% of Fund assets, while corporate high-yield bonds made up 18.5% of the
    portfolio. About 30.3% of assets were in investment-grade corporates, and
    just 1.4% of assets were invested in Treasuries.

    Because rising interest rates tend to undermine bond prices, we shortened
    the Fund's duration to lower its sensitivity to changes in interest rates.
    Duration, a measure of interest-rate sensitivity,


                                                                               9

PORTFOLIO MANAGEMENT DISCUSSION 6/30/04                              (continued)

    declined during the period from 4.7 years at the start of the fiscal year to
    4.3 years on June 30, 2004.

    Average credit quality on June 30, 2004 was A.

Q:  What is your outlook for the bond market?

A:  We believe the economy is healthy and should continue to grow. Short-term
    rates currently are below the rate of inflation and should be expected to
    continue to rise in the coming months. The Federal Reserve began to raise
    the important Fed Funds rate, the most influential short-term rate, on June
    30, and we expect further tightening by the Fed in the months ahead. We
    believe market rates on longer-term bonds, which rose in the months leading
    up to the June 30 announcement, probably are priced appropriately for
    current conditions, but pressure on shorter-term and intermediate-term
    interest rates should continue for several more quarters.

    The outlook for corporate securities appears good, however, as more
    companies gain additional pricing power, which should help them strengthen
    their balance sheets. We recently have initiated some positions in the steel
    industry, for example, an area we have generally avoided in the past.

    In this environment, we anticipate maintaining a focus on corporate bonds
    and mortgage-backed securities and expect to maintain the Fund's position to
    mute the impact of rising interest rates of short- and intermediate-term
    securities by keeping duration relatively short.

    Any information in this shareholder report regarding market or economic
    trends or the factors influencing the Fund's historical or future
    performance are statements of the opinion of Fund management as of the date
    of this report. These statements should not be relied upon for any other
    purposes. Past performance is no guarantee of future results, and there is
    no guarantee that market forecasts discussed will be realized.

1. Organization and Significant Accounting Policies

Pioneer Bond Fund (the Fund) is a Delaware statutory trust registered under the
Investment Company Act of 1940 as a diversified, open-end management investment
company. The investment objective of the Fund is to seek current income
consistent with preservation of capital. The Fund offers five classes of shares
- - Class A, Class B, Class C, Class R, and Class Y shares. Class R shares were
first publicly offered April 1, 2003. Each class of shares represents an
interest in the same portfolio of investments of the Fund and has equal rights
to voting, redemptions, dividends and liquidation, except that each class of
shares can bear different transfer agent and distributions fees and has
exclusive voting rights with respect to the distribution plans that have been
adopted by Class A, Class B, Class C, and Class R shareowners, respectively.
There is no distribution plan for Class Y shares.

The Fund's financial statements have been prepared in conformity with U.S.
generally accepted accounting principles that require the management of the Fund
to, among other things, make estimates and assumptions that affect the reported
amounts of assets and liabilities, the disclosure of contingent assets and
liabilities at the date of the financial statements, and the reported amounts of
income, expenses and gains and losses on investments during the reporting
period. Actual results could differ from those estimates. The following is a
summary of significant accounting policies 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. 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. Securities for
    which there are no other readily available valuation methods are valued at
    their fair values as determined by, or under the direction of, the Board of
    Trustees. At June 30, 2004 there were no securities fair valued. Principal
    amounts of mortgage-backed securities are adjusted for monthly paydowns. All
    discounts/premiums on debt securities are


34


Pioneer Bond Fund

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

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

    accreted/amortized for financial reporting purposes over the life of the
    respective securities, and are included in interest income. Premiums and
    discounts related to certain mortgage-backed securities are amortized or
    accreted in proportion to the underlying monthly paydowns. 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.  Federal Income Taxes

    It is the Fund's policy to comply with the requirements of the Internal
    Revenue Code applicable to regulated investment companies and to distribute
    all of its taxable income and net realized capital gains, if any, to its
    shareowners. Therefore, no federal income tax provision is required.

    The amount and characterization of distributions to shareowners for
    financial reporting purposes is determined in accordance with federal income
    tax rules. Therefore, the source of the Fund's distributions may be shown in
    the accompanying financial statements as either from or in excess of net
    investment income or net realized gain on investment transactions, or from
    paid-in-capital, depending on the type of book/tax differences that may
    exist.

    The tax character of distributions paid during the years ended June 30, 2004
    and 2003 were as follows:



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

  Distributions paid from:
   Ordinary income             $13,862,071      $13,122,468

                                                                              35

    The following shows the components of accumulated losses on a federal income
    tax basis at June 30, 2004.



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

  Undistributed ordinary income                         $   881,220
  Dividend payable                                         (229,477)
  Capital loss carryforward                              (6,403,162)
  Unrealized appreciation                                 2,826,845
                                                        -----------
    Total                                               $(2,924,574)
- -----------------------------------------------------------------------------


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

    At June 30, 2004, the Fund has reclassified $2,117,637 to increase
    accumulated net investment income and $2,117,637 to increase accumulated net
    realized loss on investments to reflect permanent book/tax differences. The
    reclassification has no impact on the net assets of the Fund and is designed
    to present the Fund's capital accounts on a tax basis.

C.  Fund Shares

    The Fund records sales and repurchases of its shares as of trade date.
    Pioneer Funds Distributor, Inc. (PFD), the principal underwriter for the
    Fund and a wholly owned indirect subsidiary of UniCredito Italiano S.p.A.,
    (UniCredito Italiano), earned $49,471 in underwriting commissions on the
    sale of Fund shares for the year ended June 30, 2004.

D.  Class Allocations

    Distribution fees are calculated based on the average daily net asset value
    attributable to Class A, Class B, Class C and Class R shares of the Fund,
    respectively. Class Y shares are not subject to a distribution plan.
    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
    3). Income, common expenses, and realized and unrealized gains


36


Pioneer Bond Fund

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

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

    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.

    The Fund declares as daily dividends substantially all of its net investment
    income. All dividends are paid on a monthly basis. Short-term capital gain
    distributions, if any, may be declared with the daily dividends.
    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, Class R and Class Y shares can bear
    different transfer agent and distribution fees.

E.  Repurchase Agreements

    With respect to repurchase agreements entered into by the Fund, the value of
    the underlying securities (collateral), including accrued interest received
    from the 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 subcustodians. 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.

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 loaned securities. The Fund has the right under the lending
    agreements to recover the securities on loan from the borrower on demand.
    The


                                                                              37

    Fund invests cash collateral in the Securities Lending Investment Fund,
    which is managed by Brown Brothers Harriman & Co., the Fund's custodian.

2. 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
0.50% of the Fund's average daily net assets. 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, 2004, $124,266 was payable to PIM related to management fees,
administrative fees and certain other services, and is included in due to
affiliates.

3. Transfer Agent

PIMSS, a wholly owned indirect subsidiary of UniCredito Italiano, provides
substantially all transfer agent and shareowner services to the Fund at
negotiated rates. Included in due to affiliates is $94,484 in transfer agent
fees payable to PIMSS at June 30, 2004.

4. Distribution and Service Plans

The Fund adopted a Plan of Distribution with respect to each class of shares
(Class A Plan, Class B Plan, Class C Plan and Class R 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. Pursuant to the
Class R Plan, the Fund pays PFD 0.50% of the average daily net assets
attributable to Class R shares for distribution services. Included in due to
affiliates is $116,126 in distribution fees payable to PFD at June 30, 2004. The
Fund also has adopted a separate service plan for Class R shares (Service Plan).
The Service Plan authorizes the Fund to pay securities dealers, plan
administrators or other service organizations that agree to provide


38


Pioneer Bond Fund

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

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

certain services to retirement plans or plan participants holding shares of the
Fund a service fee of up to 0.25% of the Fund's average daily net assets
attributable to Class R shares held by such plans.

In addition, redemptions of Class A, Class B, Class C and Class R 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%.
Redemptions of Class R shares within 18 months of purchase may be subject to a
CDSC of 1.00%. Proceeds from the CDSCs are paid to PFD. For the year ended June
30, 2004, $357,902 in CDSCs were paid to PFD.

5. 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 June 30, 2004, the Fund's expenses were
reduced by $6,036 under such arrangements.


                                                                              39

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
- --------------------------------------------------------------------------------

To the Board of Trustees and Shareowners of
Pioneer Bond Fund:

We have audited the statement of assets and liabilities, including the schedule
of investments, of Pioneer Bond Fund (the "Fund") as of June 30, 2004, and the
related statement of operations for the year then ended, the statements of
changes in net assets for each of the two years in the period then ended, and
the financial highlights for each of the periods indicated in the three years
then ended. These financial statements and financial highlights are the
responsibility of the Fund's management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits. The financial highlights for each of the two years in the period ended
June 30, 2001 were audited by other auditors who have ceased operations and
whose report, dated August 10, 2001, expressed an unqualified opinion on those
financial highlights.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we
plan and perform the audits to obtain reasonable assurance about whether the
financial statements and financial highlights are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements and financial
highlights. Our procedures included confirmation of securities owned as of June
30, 2004, by correspondence with the custodian and brokers. An audit also
includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
Pioneer Bond Fund at June 30, 2004, the results of its operations for the year
then ended, the changes in its net assets for each of the two years in the
period then ended, and the financial highlights for each of the periods
indicated in the three years then ended in conformity with U.S. generally
accepted accounting principles.

goals, offering plans suited to the individual investor and businesses of all
sizes. For more information on Pioneer retirement plans, contact your
investment professional, or call Pioneer at 1-800-622-0176.

Individual Retirement Accounts (IRAs)

Traditional IRA*
For anyone under age 70-1/2 earning income. Individuals can contribute up to
$3,000, or $3,500 if age 50 or older, annually. Earnings are tax-deferred, and
contributions may be tax-deductible.

Roth IRA*
Available to single individuals earning less than $110,000 in income annually,
and married couples with joint income less than $160,000. Contributions of up
to $3,000, or $3,500 if age 50 or older, a year are not tax-deductible, but all
earnings are tax-free for qualified withdrawals. Distributions are tax and
penalty-free if certain conditions are met.

Employer-Sponsored Plans

Uni-K Plan*
A 401(k) plan designed specifically for any business that employs only owners
and their spouses. Participants can make salary deferral contributions up to
$13,000 per year, or $16,000 if age 50 or older. In addition, each year the
business may contribute up to 25% of pay.

Uni-DB Plan
A full service defined benefit plan for small business owners over age 45 with
up to five employees. Employer contributions are required. The plan allows for
the maximum deductible contribution up to $165,000 or more.

401(k) Plan*
Allows employees to make pre-tax contributions through payroll deduction, up to
$13,000, or $16,000 if age 50 or older, per year. Employers' contributions are
discretionary. The 401(k) offers companies maximum flexibility.

Most retirement plan withdrawals must meet specific conditions to avoid
penalties.

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

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

SIMPLE IRA Plan*
The Savings Incentive Match PLan for Employees (SIMPLE) is designed for
employers with 100 or fewer eligible employees. Employees can decide whether to
contribute. Employers must contribute.

403(b) Plan*
Also known as a Tax-Sheltered Account (TSA), this plan lets employees of public
schools, non-profit hospitals and other tax-exempt organizations make pre-tax
contributions through payroll deduction.

SEP-IRA
The Simplified Employee Pension (SEP) plan lets self-employed people and
small-business owners make tax-deductible contributions of up to 25% of income,
while maintaining complete contribution flexibility each year.

Profit Sharing Plan
Companies can decide each year whether - and how much - to contribute to
participants, up to 25% of each participant's pay. Can include vesting
schedules that are not available with a SEP-IRA.

Age-Based Profit Sharing Plan
Employer contributions are flexible, but are based on a formula using age and
salary. Each year, a business can contribute up to 25% of the total eligible
payroll.

Money Purchase Pension Plan (MPP)
Allows employer contributions, up to 25% of pay annually. Companies must
contribute a fixed percentage of pay each year.

* Special Catch-Up Provisions are available to individuals age 50 and older to
  contribute additional amounts to their retirement accounts. For more
  information, call our Retirement Plans Information line at 1-800-622-0176.


Most retirement plan withdrawals must meet specific conditions to avoid

PROGRAMS AND SERVICES FOR PIONEER SHAREOWNERS
- --------------------------------------------------------------------------------

Your investment professional can give you additional information on Pioneer's
programs and services. If you want to order literature on any of the following
items directly, simply call Pioneer at 1-800-225-6292.

FactFone(SM)
This is our automated account information service, available to you 24 hours a
day, seven days a week. FactFone gives you a quick and easy way to check fund
share prices, yields, dividends and distributions, as well as information about
your own account. Simply call 1-800-225-4321. For specific account information,
have your account number, fund number and our personal identification number
(PIN) in hand. If this is your first time using FactFone, you will need to
establish a PIN.

6-Month Reinstatement Privilege (for Class A and Class B Shares)
Enables you to reinvest all or a portion of the money you redeemed from your
Pioneer account - without paying a sales charge - within 6 months from your
redemption. Upon your request, the shares will be reinvested into your choice
of any class A fund with the same registration as the originating account.
Please note that you will need to meet fund minimum requirements.

Investomatic Plan
An easy and convenient way for you to invest on a regular basis. With this
feature, Pioneer will automatically draft a predetermined dollar amount,
specified by you, from your bank account and purchase shares into your
investments to grow using the dollar-cost averaging approach.

Payroll Investment Program (PIP)
This service enables you to fund your Pioneer investment directly through a
payroll deduction. After completing Pioneer's authorization form, your employer
will deduct a predetermined dollar amount from your paycheck to be invested at
Pioneer. When you invest through payroll, you're putting yourself at the top of
the list of those you pay. Many people find that "paying yourself first" is the
most sensible way to build a nest egg.

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

Automatic Exchange Program
A simple way to move money from one Pioneer fund to another over a period of
time. Just choose the amounts and dates for Pioneer to sell shares from your
original fund and use the proceeds to buy shares of the other funds you have
chosen. To establish this service, simply complete a Pioneer Account Options
form. (Automatic Exchange is available for originating accounts with a balance
of $5,000 or more.)

Direct Deposit
Lets you move money into your bank account using electronic funds transfer
(EFT). EFT moves your money faster than you would receive a check, eliminates
unnecessary paper and mail, and avoids lost checks. Simply fill out a Pioneer
Direct Deposit Form, giving your instructions.

Systematic Withdrawal Plan (SWP)
This service allows you to establish automatic withdrawals from your account at
set intervals. You decide the frequency and the day of the month. Pioneer will
send the proceeds by check to a designated address or electronically to your
bank account. You can also authorize Pioneer to make the redemptions payable to
someone else. Simply complete a Pioneer Account Options form to begin this
service.

                                                                              51

period covered by the report, to a provision of its code of ethics that applies
to the registrant's principal executive officer, principal financial officer,
principal accounting officer or controller, or persons performing similar
functions, regardless of whether these individuals are employed by the
registrant or a third party, and that relates to any element of the code of
ethics definition enumerated in paragraph (b) of this Item. The registrant must
file a copy of any such amendment as an exhibit pursuant to Item 10(a), unless
the registrant has elected to satisfy paragraph (f) of this Item by posting its

undertaking to provide its code of ethics to any person without charge, upon
request, pursuant to paragraph (f)(3) of this Item.

The registrant has made no amendments to the code of ethics during the period
covered by this report.

(d) If the registrant has, during the period covered by the report, granted a

        (2) Post the text of such code of ethics on its Internet website and

least one audit committee financial expert.

    (2) If the registrant provides the disclosure required by paragraph
(a)(1)(i) of this Item, it must disclose the name of the audit committee
financial expert and whether that person is "independent." In order to be

committee, the board of trustees, or any other board committee:

    (i)  Accept directly or indirectly any consulting, advisory, or other
         compensatory fee from the issuer; or

financial expert.

Not applicable.

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

                  SECTION I - POLICY PURPOSE AND APPLICABILITY

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

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

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

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

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

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

o Potential services will be classified into the four non-restricted service

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

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

with the adviser that provides ongoing services to the registrant for each of
the last two fiscal years of the registrant.

affiliates, as previously defined, totaled approximately
$6,000 in 2004 and $3,600 in 2003.

(h) Disclose whether the registrant's audit committee of the board of trustees
has considered whether the provision of non-audit services that were rendered to
the registrant's investment adviser (not including any subadviser whose role is
primarily portfolio management and is subcontracted with or overseen by another
investment adviser), and any entity controlling, controlled by, or under common
control with the investment adviser that provides ongoing services to the

accountant's independence.

Non-Audit Services
Beginning with non-audit service contracts entered
into on or after May 6, 2003, the effective date of the
new SEC pre-approval rules, the Fund's audit
committee is required to pre-approve services to
affiliates defined by SEC rules to the extent that the
services are determined to have a direct impact on the
operations or financial reporting of the Fund. For the
years ended June 30, 2004 and 2003, there were no
services provided to an affiliate that required the
Fund's audit committee pre-approval.

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