LETTER TO SHAREOWNERS 12/31/04
- --------------------------------------------------------------------------------

DEAR SHAREOWNER,
- --------------------------------------------------------------------------------
After three calendar quarters of listless performance, U.S. equity markets
improved strongly late in the year. Anxiety over energy prices, international
tensions and the falling American dollar had held the markets back, but
uneasiness about the presidential election was the principal source of investor
hesitation. The election went smoothly, the result was decisive, and the ensuing
rally pushed major indices into the black for the second year running. However,
returns trailed 2003's levels. Small capitalization companies outperformed
large-cap issues for the sixth consecutive year. Markets overseas were generally
buoyant: commodity-rich nations saw surging demand for copper, iron ore, lumber
and other materials, with much of their output destined to feed China's vast
economic appetite.

Bond investors focused on longer-term issues. Reflecting the risk preference
that favored small-cap stocks, high-yield bonds were the strongest performers,
while higher quality issues, including U.S. Treasury issues, scored more modest
gains. Municipal bond returns were generally favorable as well; economic growth
spurred rising tax revenues, putting many issuers into surplus for the first
time in years.

A measured pace of growth seems in store for the U.S. economy, which generated
2.2 million jobs after years of employment declines. By the end of September,
the economy had tallied 12 positive quarters, and the nation's annualized growth
rate stood at a respectable four percent. We believe this rate of expansion is
enough to sustain growth without provoking the Federal Reserve Board into
aggressive interest rate hikes aimed at calming inflation.

NEW INVESTMENT CHOICES

Pioneer Investment Management recently acquired twenty-two former Safeco mutual
funds. After merging some Safeco offerings into existing Pioneer funds with
similar goals and strategies, Pioneer now offers seven new products, including
municipal bond funds and funds focused on growth. The transaction underscores
Pioneer's growing presence in the ranks of major U.S. management firms and
significantly broadens the investment options available to you. A conversation
with your investment professional will help you understand how these new funds
may enhance your portfolio diversification and fit in with your long-range
goals.

Please consider a fund's investment objective, risks, charges and expenses
carefully before investing. The prospectus contains this and other information
about each 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
financial advisor, call 1-800-225-6292 or visit our web site at

COMPARING ONGOING FUND EXPENSES
- --------------------------------------------------------------------------------

As a shareowner in the Fund, you incur two types of costs:

(1)  ongoing costs, including management fees, distribution and/or service
     (12b-1) fees, and other Fund expenses; and

(2)  transaction costs, including sales charges (loads) on purchase payments.

This example is intended to help you understand your ongoing expenses (in
dollars) of investing in the Fund and to compare these costs with the ongoing
costs of investing in other mutual funds. The example is based on an investment
of $1,000 at the beginning of the Fund's latest six-month period and held
throughout the six months.

USING THE TABLES

ACTUAL EXPENSES

The first table below provides information about actual account values and
actual expenses. You may use the information in this table, together with the
amount you invested, to estimate the expenses that you paid over the period as
follows:

1.   Divide your account value by $1,000
     Example: an $8,600 account value / $1,000 = 8.6

2.   Multiply the result in (1) above by the corresponding share class's number
     in the third row under the heading entitled "Expenses Paid During Period"
     to estimate the expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

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

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

PLEASE NOTE THAT THE EXPENSES SHOWN IN THE TABLES ARE MEANT TO HIGHLIGHT YOUR

PORTFOLIO MANAGEMENT DISCUSSION 12/31/04
- --------------------------------------------------------------------------------

For the fifth year in a row, real estate stocks achieved positive returns and
outperformed the broader market indices. Performance by property type was
universally strong. As Matthew Troxell of AEW Capital Management, L.P. (the
Fund's subadvisor) explains in the following interview, it will fall to astute
stock selection to identify the real estate investments most likely to continue
this momentum into the New Year after such a rewarding multi-year rally.

Q:   WHAT CONTRIBUTED TO SUCH FAVORABLE RETURNS IN THE REAL ESTATE MARKET?

A:   We think three factors contributed to the success of real estate in 2004.
     First, real estate investments have taken on greater appeal as the sector
     has matured over the last 20 years. Improved transparency and corporate
     reporting are helping investors follow this market with greater ease.
     Secondly, following the implosion of technology stocks in the late 1990s,
     investors gained a renewed understanding of the benefits of diversification
     to reduce risk. Real estate stocks as an asset class benefited from the
     increased demand. Finally, given the historically low interest rates we've
     seen in recent years, income-seeking baby boomers and retirees have turned
     to the real estate market in increasing numbers as its ability to generate
     income and modest growth over time have become more widely understood.

Q:   HOW DID THE FUND PERFORM DURING FISCAL 2004?

A:   For the 12 months ended December 31, 2004, the Fund's Class A shares rose
     35.26%, at net asset value. The Fund's performance slightly surpassed the
     Wilshire Real Estate Securities Index, which increased 34.81% for the same
     period. The Fund's performance also surpassed the 32.05% average return of
     the 212 real estate funds tracked by Lipper Inc. (Lipper Inc. is an
     independent firm that measures mutual fund performance.)

     THE PERFORMANCE DATA QUOTED REPRESENTS PAST PERFORMANCE, WHICH IS NO
     GUARANTEE OF FUTURE RESULTS. Investment return and principal value will
     fluctuate, and shares, when redeemed, may be worth more or less than their
     original cost.

Q:   WHAT INVESTMENTS CONTRIBUTED TO PERFORMANCE?

A:   Due to effective securities selection, the Fund's investments in regional
     mall, office, apartment and hotel investments were

                                                                               9


PIONEER REAL ESTATE SHARES

- --------------------------------------------------------------------------------
PORTFOLIO MANAGEMENT DISCUSSION 12/31/04                             (CONTINUED)
- --------------------------------------------------------------------------------

     particularly rewarding. Strong operating fundamentals at the property level
     and healthy consumer spending patterns boosted returns of regional mall
     real estate investment trusts (REITs). One of the Fund's largest holdings,
     Simon DeBartolo Group, performed strongly in the last quarter of the fiscal
     year. As we mentioned in our last report, that REIT announced the
     acquisition of Chelsea property Group (also held by the Fund) during the
     first half of the fiscal year. Initially, investors reacted negatively. But
     we viewed the proposed merger very positively because we thought Chelsea
     Property Group, which owns factory outlet shopping centers in Japan as well
     as in the United States, would add international diversity and a new avenue
     of growth to Simon. Each company's board of directors and Chelsea's
     shareholders approved the definitive merger agreement, and the company's
     stock rallied nicely.

     While the outlook for the office sector is improving as a result of
     positive job growth, it takes longer for the improvements to manifest
     themselves at the property owner level. (Tenants must first use their
     existing empty space before seeking new office space.) While we remain
     cautiously optimistic about this sector, Boston Properties exemplifies the
     kind of resilient, well-managed office REITs that has weathered the office
     downturn better than many of its counterparts. Boston Properties holds a
     portfolio of high-quality buildings concentrated in four markets with high
     barriers to entry - San Francisco, Boston, Midtown Manhattan and Washington
     D.C. This office REIT returned 42.5% for 2004, well ahead of the index
     (34.81%).

     A sector of the real estate market that recovered well in 2004 was
     apartments. AvalonBay Communities, which we'd chosen to emphasize for much
     of the year, was one of the Fund's best performing stocks for this
     reporting period. Like the office sector, multi-family housing is
     benefiting from positive job growth, which helps increase demand for
     apartments. In addition, job growth is favorable for household formations,
     especially young adults renting for the first time. Finally, we're seeing
     tremendous demand for the conversion of apartments to condominiums in a
     number of markets, including southeast Florida and southern California,
     where the price of owning a home is prohibitive for many people. In sum,
     increased demand is improving fundamentals while condo conversion demand
     provides support for asset prices - an ideal scenario that creates a
     natural price support.

     Lastly, in the lodging sector, our selection of hotels did well, but it
     was the presence of Starwood Hotels and Resorts that dramatically impacted
     performance with its 64.7% return for 2004. That hotel, like many in its
     universe, saw great improvement in occupancy rates -- resulting in a
     greater number of rooms being rented in 2004 than 2003. Much of the
     improvement was due to the ability of management to increase room rates,
     which is a more powerful driver of profitability than occupancy rates. The
     degree to which hotels were able to raise room rates was a surprising and
     welcome development in what came to be a very rewarding year.

Q:   ANY STOCKS PROVE TO BE DISAPPOINTING?

A:   The fundamentals for all property types improved during 2004, including
     industrial stocks. However, despite their positive performance, the sector
     proved to be a detractor for performance relatively speaking, since the
     group underperformed the index. Given their returns, our decision to carry
     a slightly greater-than-benchmark weighting didn't help. The Fund's
     investments in Liberty Property Trust, an office and industrial REIT,
     lagged the market. Investors became worried about the delay in construction
     due to management's decision to find an anchor tenant before building a new
     office tower in downtown Philadelphia. When Comcast signed on as a tenant,
     the stock began to recover. We remain confident that the management at
     Liberty has a good understanding of their business and retains strong
     assets.

Q:   WHAT IS YOUR OUTLOOK?

A:   With the underlying fundamentals improving, real estate stocks appear
     poised to continue strengthening. However, after such impressive
     performance during the past five years, we would not be surprised to see a
     moderating of performance returns in 2005. As the proverbial tide lifts all
     boats, blurring the line between losers and winners, we expect to take a
     more cautious approach knowing that astute securities selection will be
     even more important in the new fiscal year.

1.   ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

Pioneer Real Estate Shares (the Fund) is a Delaware statutory trust registered
under the Investment Company Act of 1940 as a non-diversified, open-end
management investment company. The investment objective of the Fund is to seek
long-term growth of capital. Current income is a secondary objective.

The Fund offers four classes of shares - Class A, Class B, Class C, and Class Y
shares. 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 distribution fees and have exclusive voting rights with respect to the
distribution plans that have been adopted by Class A, Class B and Class C
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 year.
Actual results could differ from those estimates. The following is a summary of
significant accounting policies followed by the Fund in the preparation of its
financial statements, which are consistent with those policies generally
accepted in the investment company industry.

A.   SECURITY VALUATION

     Security transactions are recorded on trade date. The net asset value of
     the Fund is computed once daily, on each day the New York Stock Exchange
     (NYSE) is open, as of the close of regular trading on the NYSE. In
     computing the net asset value, securities 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 Board of Trustees. Trading in foreign securities is
     substantially completed

                                                                              23


PIONEER REAL ESTATE SHARES

NOTES TO FINANCIAL STATEMENTS 12/31/04                               (CONTINUED)
- --------------------------------------------------------------------------------

     each day at various times prior to the close of the NYSE. The values of
     such securities used in computing the net asset value of the Fund's shares
     are determined as of such times. The Fund also may use the fair value of a
     security, including a non-U.S. security, when the closing market price on
     the principal exchange where the security is traded no longer reflects the
     value of the security. At December 31, 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 the exercise of reasonable diligence. Interest income
     is recorded on the accrual basis. Temporary cash investments are valued at
     amortized cost.

     Because the Fund may invest a substantial portion of its assets in Real
     Estate Investment Trusts (REITs), the Fund may be subject to certain risks
     associated with direct investments in REITs. REITs may be affected by
     changes in the value of their underlying properties and by defaults of
     their borrowers or tenants. REITs depend generally on their ability to
     generate cash flow to make distributions to share-owners, and certain REITs
     have self-liquidation provisions by which mortgages held may be paid in
     full and distributions of capital returns may be made at any time. In
     addition, the performance of a REIT may be affected by its failure to
     qualify for tax-free pass-through of income under the Internal Revenue Code
     or its failure to maintain exemption from registration under the Investment
     Company Act of 1940.

     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 amounts and characterizations of distributions to shareowners for
     financial reporting purposes are determined in accordance with federal
     income tax rules. Therefore, the sources of the Fund's distributions

24


PIONEER REAL ESTATE SHARES

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

     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. A portion of the dividend income recorded by
     the Fund is from distributions by publicly traded REITs, and such
     distributions for tax purposes may also consist of capital gains and return
     of capital. The actual return of capital and capital gains portions of such
     distributions will be determined by formal notifications from the REITs
     subsequent to the calendar year-end. Distributions received from the REITs
     that are determined to be a return of capital, are recorded by the Fund as
     a reduction of the cost basis of the securities held.

     The tax character of distributions paid during the years ended December 31,
     2004 and 2003 were as follows:

                              2004           2003

*    Included in the Fund's distributions from 2004 ordinary income is $360,268
     in excess of investment company taxable income, which, in accordance with
     applicable U.S. tax law, is taxable to share-owners as ordinary income
     distributions.

     The following shows the components of distributable earnings on a federal
     income tax basis at December 31, 2004.

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

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

     At December 31, 2004, the Fund has reclassified $26,070 to decrease net
     accumulated realized loss on investments, $302,804 to increase
     undistributed net investment income and $328,874 to decrease paid in
     capital. The reclassification has no impact on the net assets of the Fund
     and presents the Fund's capital accounts on a tax basis.

C.   FUND SHARES

     The Fund records sales and repurchases of its shares on 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). PFD earned $126,649 in underwriting commissions on the sale of
     Class A shares during the year ended December 31, 2004.

D.   CLASS ALLOCATIONS

     Distribution fees are calculated based on the average daily net asset value
     attributable to Class A, Class B and Class C shares of the Fund,
     respectively. Class Y shares are not subject to a distribution plan (see
     Note 4). 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 and losses are calculated at the Fund level and allocated daily to
     all classes of shares based on their 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 Class Y can bear different
     transfer agent and distribution fees.

E.   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
     payments in lieu of 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 the
     Securities Lending Investment Fund, which is managed by Brown Brothers
     Harriman & Co., the Fund's custodian.

F.   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 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.

2.   MANAGEMENT AGREEMENT

PIM, a wholly owned indirect subsidiary of UniCredito Italiano, manages the
Fund's portfolio. Management fees are calculated daily at the annual rate of
0.80% of the Fund's average daily net assets. Effective May 3, 2004, AEW
Management and Advisors LP (AEW) became subadvisor to the Fund.

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

                                                                              27

administrative costs 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 $33,239 in transfer agent
fees payable to PIMSS at December 31, 2004.

4.   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 Fund's 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 $71,512 in distribution fees payable to PFD at December 31,
2004.

In addition, redemptions of each class of shares (except Class Y shares) may be
subject to a contingent deferred sales charge (CDSC). Effective February 1,
2004, a CDSC of 1.00% may be imposed on redemptions of certain net asset value
purchases of Class A shares within 18 months of purchase (12 months for shares
purchased prior to February 1, 2004). Effective December 1, 2004, Class B shares
that are redeemed within five years of purchase are subject to a CDSC at
declining rates beginning at 4.0%, based on the lower of cost or market value of
shares being redeemed. Shares purchased prior to December 1, 2004 remain subject
to the CDSC in effect at the time those shares were purchased. Redemptions of
Class C shares within one year of purchase are subject to a CDSC of 1.00%.
Proceeds from the CDSC are paid to PFD. For the year ended December 31, 2004,
CDSCs in the amount of $35,709 were paid to PFD.

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, 2004, the Fund's expenses
were reduced by $2,517 under such arrangements.

6.   LINE OF CREDIT FACILITY

The Fund along with certain other funds 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, 2004, the Fund had no borrowings under this agreement.

                                                                              29

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

TO THE BOARD OF TRUSTEES AND SHAREOWNERS OF PIONEER REAL ESTATE SHARES:

We have audited the accompanying statement of assets and liabilities, including
the schedule of investments, of Pioneer Real Estate Shares (the "Fund") as of
December 31, 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 three years in
the period then ended. These financial statements and financial highlights are
the responsibility of the Fund's management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits. The financial highlights for each of the two years in the period ended
December 31, 2001 were audited by other auditors who have ceased operations and
whose report, dated February 15, 2002, 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 per form the audit to obtain reasonable assurance about whether the
financial statements and financial highlights are free of material misstatement.
An audit includes consideration of internal control over financial reporting as
a basis for designing audit procedures that are appropriate in the
circumstances, but not for the purpose of expressing an opinion on the
effectiveness of the Fund's internal control over financial reporting.
Accordingly, we express no such opinion. An audit also includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements and financial highlights, assessing the accounting principles used
and significant estimates made by management, and evaluating the overall
financial statement presentation. Our procedures included con-firmation of
securities owned as of December 31, 2004, by correspondence with the custodian
and brokers or by other appropriate auditing procedures where replies from
brokers were not received. We believe that our audits provide a reasonable basis
for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
Pioneer Real Estate Shares at December 31, 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 three
years in the period then ended, in conformity with U.S. generally accepted
accounting principles.

Current performance may be lower or higher than the performance data quoted.

THE PERFORMANCE DATA QUOTED REPRESENTS PAST PERFORMANCE, WHICH IS NO GUARANTEE
OF FUTURE RESULTS. Investment return and principal value will fluctuate, and
shares, when redeemed, may be worth more or less than their original cost.

Per formance results reflect any applicable expense waivers in effect during the
periods shown. Without such waivers fund per formance would be lower. Waivers
may not be in effect for all funds and can be rescinded at any time. See the
prospectus and financial statements for complete details.

90-DAY REINSTATEMENT PRIVILEGE (FOR CLASS A AND CLASS B SHARES)

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.

The use of a systematic investing program does not guarantee a profit or protect
against a loss in declining markets. You should consider your financial ability
to continue to invest through periods of low prices.

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.

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

 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.

                 firm, the scope of the Audit

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

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

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

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


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

    N/A

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

N/A

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

The Fund's independent auditor, Ernst & Young
LLP ("E&Y"), recently has advised the Securities
and Exchange Commission, the Public Company
Accounting Oversight Board, and the Audit
Committee of the Fund's Board of Trustees that
certain non-audit work performed by E&Y's China
affiliate has raised questions regarding E&Y's
independence with respect to its performance of
audit services for the Fund.  In July 2004, E&Y
became aware that member firms in China ("E&Y
China") provided certain tax services to offices of
UniCredito Italiano, S.p.A. ("UCI"), a member of
the Fund's Investment Company Complex.  The
services included receipt and disbursement of
monies transferred to E&Y China by UCI in
payment of individual expatriate income taxes due
on returns prepared by E&Y China for certain UCI
employees located in China from October 1998 to
May 2003.  E&Y became auditors of the Fund in
May 2002.  These expatriate tax services were
discontinued in May 2003.  The fees received by
E&Y China for all such services totaled $3,685.

The Fund's Audit Committee and E&Y have
discussed the matter, including the nature of the
services provided, the personnel involved in
providing the services and the fees received by
E&Y for performing the services.  The Committee
continues to review the facts and circumstances
surrounding the matter, including the issue of
whether the monies transferred for employees' taxes
were de facto monies due the employees for tax
payments rather than monies belonging to UCI.
E&Y has informed the Audit Committee that based
on its internal reviews and the de minimis nature of
the services provided and fees received, it does not
believe its independence with respect to the Fund
has been impaired.


Aggregate Non-Audit Fees

The aggregate non-audit fees for the Fund and affiliates, as
previously defined, totaled approximately $6,000 in 2004 and
$71,500 in 2003. These fees include services provided prior to
May 6, 2003, the effective date of the pre-approval process

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.



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

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 Funds 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 December 31, 2004 and 2003, there were no services provided to an
affiliate that required the Funds audit committee pre-approval.
