 Dear Shareowner,
- --------------------------------------------------------------------------------
We know from the history of the capital markets that sudden shifts in investor
sentiment can occur with little warning, based on an assortment of events. We
believe such a shift in sentiment is occurring in reaction to the possibility
that U.S. economic growth may slow in the second half of 2006.

While U.S. markets fell in late May and early June, the economic events of the
six- and 12-month periods ending June 30, 2006, have actually been characterized
by continued low inflation at home and strong growth prospects abroad with
rising commodity and stock prices.

According to the International Monetary Fund, international economic growth in
2004-5 was the fastest of any two-year period in more than 30 years, and 2006
growth is projected to match the healthy growth of 2005. The growth has been
broad-based, with Europe, Japan, and emerging market economies all showing
strength. The result has been rising prices across a broad range of commodities,
increasing corporate profits, and higher interest rates.

The U.S. bond markets' concern has been that strong economic growth would spark
inflation - we have already seen commodity prices rise, and U.S. labor costs are
threatening to increase, since we are close to full employment. That may also be
a reason why public sentiment is becoming uneasy.

Despite strong first quarter economic growth, the U.S. economy for the second
half of the year may slow in reaction to past increases in interest rates and
energy costs. Thus far the only sign of such a slowdown has been a cooling
housing market. Yet many observers believe a slower growing economy could be
welcomed by the markets.

The U.S. Federal Reserve has continued its program of measured short-term
interest rate increases. However, the Fed Chairman, Ben Bernanke, indicated that
inflation may moderate, which would permit the Fed to stop raising interest
rates. Such action could have positive effects for both consumers and investors
over the intermediate to longer term. By restraining inflation, the Fed may also
limit upward

pressure on longer-maturity bond yields and downward pressure on stocks'
price/earnings ratios.

In summary, we think security market valuations remain reasonable, and yet there
are no guarantees in investing. The unpredictability reinforces the importance
of Pioneer's message that investors should remain diversified, take a long-term
view, and base investment decisions on economic and market fundamentals, rather
than on emotion. Our investment philosophy and approach continue to be based on
the use of fundamental research to identify a range of opportunities that offer
an attractive balance of risk and reward to help shareowners work toward their
long-term goals.



Respectfully,

/s/ Osbert M. Hood

PORTFOLIO MANAGEMENT DISCUSSION 6/30/06
- --------------------------------------------------------------------------------

Real estate investments enjoyed strong performance during the six months ended
June 30, 2006 - the first half of Pioneer Real Estate Shares' fiscal year.
While performance gains were generally positive across the various sectors of
the real estate market, the Fund's investments in the apartment and office
sectors proved very rewarding, as Portfolio Manager Matthew Troxell of AEW
Capital management, L.P., the Fund's Sub-Advisor, explains in the following
interview.

Q:   How well did the Fund perform during the six months ended June 30, 2006?

A:   The Fund posted strong performance, both on an absolute basis and relative
     to its benchmark and competitive universe. For the first half of fiscal
     2006, the Fund's Class A shares returned 14.45% at net asset value. In
     comparison, the Fund's benchmark, the Wilshire Real Estate Securities
     Index, posted 14.08% for the same six-month period. The average return for
     the 251 funds in the Fund's Lipper category of real estate funds was
     12.70%. We think effective stock selection and the portfolio's
     greater-than-benchmark weighting in the apartment sector contributed to
     these results.

     Call 1-800-225-6292 or visit www.pioneerinvestments.com for the most recent
     month-end performance results. 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.

Q:   Could you highlight the sectors of the real estate market - and some stocks
     within those industries - that contributed to performance?

A:   Our decision to emphasize investments in the apartment sector during the
     reporting period proved to be very rewarding. The sector's outlook has
     improved, as many of the negative factors that had overshadowed this group
     of stocks and depressed investor demand have dissipated.

     Several factors contributed to increased demand for apartments. With the
     return of higher interest rates, renting has

Pioneer Real Estate Shares
- --------------------------------------------------------------------------------

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

     become a more attractive option relative to buying a home. In addition,
     property values appear to have leveled off or even declined in some markets
     - thereby discouraging potential homebuyers that might have been drawn to
     the rising equity values offered by owning a home.

     At the same time, the growth in the supply of apartments has remained in
     check, in part due to the escalating cost of new construction. Moreover,
     during the last few years, many apartments were converted into condominiums
     to meet the high demand for home ownership. This development has resulted
     in a reduced supply of apartments in the face of today's rising demand in
     some markets. This is benefiting the bottom line of the apartment real
     estate investment trust (REIT) operators, since landlords are better able
     to maintain full occupancy. With stronger demand, landlords have greater
     pricing power and are able to push through rent increases.

     One of the Fund's holdings, Camden Properties, dramatically outperformed
     for the six months ended June 30, 2006. We have a high level of confidence
     in the management team of this REIT, which is embracing technological
     innovations to improve efficiency and maximize revenue. The company owns
     high-quality properties, which they manage very effectively in our opinion.

Q:   Did office REITs also experience a resurgence?

A:   Yes, and for similar reasons, albeit with somewhat of a lag versus the
     multifamily sector. After a protracted period of underperformance as a
     result of declining occupancies, the office sector has begun to see
     fundamentals improve. In fact, in some markets, such as New York City,
     rents have returned to the previous peak levels experienced during the
     technology boom of the late 1990s and early 2000. With the U.S. economy
     prospering and job growth expanding, demand for office space is increasing
     occupancy as existing tenants expand their businesses or new tenants
     arrive. As with the apartment sector, the increased demand has allowed
     landlords to raise rents.

     Announcements of two large all-cash privatizations in the office sector in
     the first half of the year (CarrAmerica Realty and Trizec Properties) on
     the heels of the acquisition of Arden Realty underscored tremendous
     investor interest in office properties.

                                                                               5

     Highwoods Properties, an overweight holding of the Fund, rose dramatically
     in the final weeks of the reporting period in response to an unsolicited
     offer for the company at a value substantially higher than the trading
     price. While the offer was quickly rejected by the board, we think it
     corroborated the inherent value that we'd seen in the stock for some time.

     One of the Fund's holdings, Equity Office Properties, also was a strong
     performer for the semiannual period. However, we'd limited the Fund's
     exposure to this REIT, because we had concerns about the ability of the
     company to participate fully in the nascent office recovery.

Q:   Is the mall sector still benefiting from the economic recovery?

A:   Yes, but to a lesser degree than apartment or office REITs because regional
     malls and shopping centers had already enjoyed strong outperformance
     relative to other property types for some time. Over the past few years,
     healthy consumer spending has supported strong operating results at the
     property level.

     Two of the Fund's holdings produced contrasting results and contributed to
     weaker albeit positive results during the reporting period. The Fund
     benefited from its overweight position in Taubman Centers, which
     outperformed both the mall group and the Index. The Fund's position in
     Mills hurt absolute performance as it posted a negative total return, but
     not relative performance as the Fund's holding was significantly less than
     the Index weighting.

     The Fund's investment in Mills Corp. turned in disappointing performance,
     because of questions surrounding the company's financial reporting and a
     proposed large-scale project in New Jersey. In contrast, Taubman Centers
     delivered strong performance consistent with its high-quality portfolio,
     and its considerable weighting in the portfolio magnified this result.

Q:   What is your outlook for balance of the fiscal year?

A:   We think that the fundamentals across most property types should continue
     to improve for the foreseeable future - although to varying degrees since
     their respective lease terms make them respond differently to the economic
     recovery. For instance, hotels, with their one-night lease terms can
     effectively adjust daily to the strength in their market. On the other
     hand, offices respond more

Pioneer Real Estate Shares
- --------------------------------------------------------------------------------

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

     slowly to economic growth because they typically have leases that run three
     to five years. Our investment approach will continue to monitor fundamental
     trends and seek out investments offering the most attractive value.

     As we have mentioned to you in past reports, the multi-year rally in real
     estate stocks has produced tremendous appreciation. Our valuation analyses
     suggest that shares are fully valued based on valuation metrics that are
     well above historical averages. On the other hand, there are a number of
     sound arguments that lend support to these higher metrics, and demand for
     commercial real estate continues to be strong on both a public and private
     basis. We will continue to assess every holding - paring back positions in
     companies that have become overpriced in our estimation while adding to
     positions in relatively undervalued companies - to help build long-term
     value and appreciation for our shareowners.

     The Fund invests in REIT and REOC securities, the value of which can fall
     for a variety of reasons, such as declines in rental income, fluctuating
     interest rates, poor property management, environmental liabilities,
     uninsured damage, increased competition, or changes in real estate tax
     laws. At times, the Fund's investments may represent industries or industry
     sectors that are interrelated or have common risks, making it more
     susceptible to any economic, political, or regulatory developments or other
     risks affecting those industries or sectors.

     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

     month-end performance results. 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.

     NAV results represent the percent change in net asset value per share.
     Returns would have been lower had sales charges been reflected. POP returns
     reflect deduction of maximum 5.75% sales charge. All results are historical
     and assume the reinvestment of dividends and capital gains. Other share
     classes are available for which performance and expenses will differ.

     Performance results reflect any applicable expense waivers in effect during
     the periods shown. Without such waivers Fund performance would be lower.
     Waivers may not be in effect for all funds. Certain fee waivers are
     contractual through a specified period. Otherwise, fee waivers can be
     rescinded at any time. See the prospectus and financial statements for more

     "If Held" results represent the percent change in net asset value per

     CDSC is applied to withdrawals was shortened to 5 years. The maximum CDSC
     for class B shares continues to be 4%. For more complete information,

     December 1, 2004 remain subject to the CDSC in effect at the time you
     purchased those shares. For performance information for shares purchased

     Class C shares held for less than one year are also subject to a 1%

     does not reflect the 1% front-end sales charge in effect prior to February
     1, 2004. If you paid a 1% sales charge, your returns would be lower than
     those shown above. "If Held" results represent the percent change in net

     month-end performance results. 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.

     Performance for periods prior to the inception of Class Y shares reflects
     the NAV performance of the Fund's Class A shares. The performance does not
     reflect differences in expenses, including the Rule 12b-1 fees applicable
     to Class A shares. Since fees for Class A shares are generally higher than
     those of Class Y shares, the performance shown for Y shares prior to its
     inception would have been higher. Class A shares are used as a proxy
     through April 9, 1998. Class Y shares are not subject to sales charges and
     are available for limited groups of eligible investors, including
     institutional investors. All results are historical and assume the
     reinvestment of dividends, and capital gains. Other share classes are
     available for which performance and expenses will differ.

     Performance results reflect any applicable expense waivers in effect during
     the periods shown. Without such waivers Fund performance would be lower.
     Waivers may not be in effect for all funds. Certain fee waivers are
     contractual through a specified period. Otherwise, fee waivers can be
     rescinded at any time. See the prospectus and financial statements for more
     information.

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 [divided by] $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
ongoing costs only and do not reflect any transaction costs, such as sales
charges (loads) that are charged at the time of the transaction. Therefore, the
table below is useful in comparing ongoing costs only and will not help you
determine the relative total costs of owning different funds. In addition, if
these transaction costs were included, your costs would have been higher.

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 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.

Information regarding the Fund's principal risks is contained in the Fund's
prospectus. Please refer to those documents when considering the Fund's risks.
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 shareowners, 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.

The following is a summary of significant accounting policies followed by the
Fund in the preparation of its financial statements, which are


                                                                              27


Pioneer Real Estate Shares
- --------------------------------------------------------------------------------
NOTES TO FINANCIAL STATEMENTS 6/30/06 (unaudited)                  (continued)
- --------------------------------------------------------------------------------

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 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
    June 30, 2006 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.

    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

28


Pioneer Real Estate Shares
- --------------------------------------------------------------------------------

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

    federal income tax rules. Therefore, the sources 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. 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 current year distributions paid will be determined at
    the end of the current fiscal year. The tax character of distributions
    paid during the year ended December 31, 2005 was as follows:



- -----------------------------------------------
                                    2005

                                13,819,772
  Return of capital                858,710
                               -----------
    Total                      $14,678,482
                               ===========
- -----------------------------------------------


    The following shows the components of distributable earnings on a
     federal income tax basis at December 31, 2005.

  Undistributed Ordinary Income     $   391,750
  Unrealized appreciation            62,604,982
                                    -----------
    Total                           $62,996,732

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

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 $26,097 in underwriting commissions on
    the sale of Class A shares during the six months ended June 30, 2006.

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

30


Pioneer Real Estate Shares
- --------------------------------------------------------------------------------

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

    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 sponsored 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 31, 2004, AEW
Management and Advisors LP (AEW) became subadvisor to the Fund. PIM pays a
portion of the fee it receives from the Fund to AEW as compensation for
sub-advisory services 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 June 30, 2006, $4,389 was payable to PIM
related to management fees, 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 $41,968 in transfer agent
fees payable to PIMSS at June 30, 2006.


                                                                              31

4. Distribution Plans

The Fund adopted a Plan of Distribution with respect to Class A, Class B and
Class C 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 $2,228 in distribution fees payable to PFD at June 30,
2006.

In addition, redemptions of each class of shares (except Class Y 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 18 months of purchase. Class B shares subscribed on or after December 1,
2004 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 six months ended June
30, 2006, CDSCs in the amount of $27,636 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 six months ended June 30, 2006, the Fund's expenses
were not reduced 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

32


Pioneer Real Estate Shares
- --------------------------------------------------------------------------------

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

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 six months ended June 30, 2006, the Fund had no
borrowings under this agreement.

                                                                              33

 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 recognize 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 recognize 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

  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.

for services rendered to the registrant, and rendered to the registrant's
investment adviser (not including any sub-adviser whose role is primarily

investment adviser), and any entity controlling, controlled by, or under common

The Fund's independent auditor, Ernst &

Committee of the Fund's Board of Trustees that
E&Ys Spanish affiliate (E&Y Spain) performed
certain non-audit work for Pioneer Global

to E&Y Spain by PGIL in payment of individual
payroll and related income tax withholdings due on
returns prepared by E&Y Spain for certain PGIL
employees located in Spain from February 2001 to
October 2005.  E&Y became auditors of the Fund in
May 2002.  These payroll and tax services were
discontinued in November 2005.  The annual fee
received by E&Y Spain for all such services totaled
approximately 9,000 Euro per year. E&Y has informed
the Audit Committee that based on its internal
reviews and the de minimus nature of the services
provided and fees received, E&Y does not believe
its independence with respect to the Fund has been
impaired or that it is disqualified from acting as
independent auditors to the Fund.
