Dear Shareowner,
- --------------------------------------------------------------------------------
Staying diversified and keeping your portfolio invested in the markets are two
general investment principles that have served investors well over time. Those
were particularly useful guides during the past year, as U.S. and global stock
and bond markets grew strongly during the period.

In recent months, U.S. equity markets proved resilient in the face of a slowing
economy. The Standard & Poor's 500 Stock Index set a record high in late May.
The Dow Jones Industrial Average returned 9%, building on a five-year bull
market. International developed and emerging markets equities performed even
better than U.S. equities, with the MSCI EAFE (developed market) Index
returning 11% and the MSCI Emerging Markets Index returning 18% in the first
half of 2007.

The general U.S. bond market, as measured by the Lehman Brothers Aggregate Bond
Index, returned 1% in the first half, as rising bond yields produced price
declines that partially offset income earned. The high yield market, as
measured by the Merrill Lynch High Yield Bond Master II Index, returned 3%,
reflecting its higher yields and continuing investor confidence in the strength
of the U.S. economy.

The United States has enjoyed a cyclical recovery with strong economic growth.
While the growth has slowed recently, we believe that continuing growth at a
moderate rate appears to be more likely than a recession. Slowing growth was
due in large part to a decline in the rate of new home construction and in part
to the lagging effects of rising energy and commodity prices as well as rising
short-term interest rates. Slowing economic activity is also due in part to the
natural maturation of the cyclical expansion as U.S. factories approach full
utilization and the labor market approaches full employment. This slowdown is
therefore not entirely unwelcome, as it reduces the threat of higher inflation.

The Federal Reserve Board (the Fed) continues to highlight its commitment to
keeping inflationary pressures contained. This is in keeping with "best
practices" among the world's central banks: low and stable inflation is
believed to be the best backdrop for stable economic growth and low average
unemployment over the long term. Keeping inflation low is also an important
support for stock and bond valuations, and so the Fed's policy is
investor-friendly.

In Europe, solid GDP growth driven by a positive operating environment for
European companies, especially those that are benefiting from strong export
markets for their goods and services, is driving unemployment lower and
supporting growing consumption.

Letter

European inflationary pressures appear to be largely under control, with the
European Central bank remaining strongly vigilant. Japanese economic growth
continues to make progress, and the country has become a more attractive market
as deflationary problems recede. Economic growth in emerging market countries
remains faster than in the developed world as they continue to "catch up."
Leading the way is China, which continues its rise as a world economic power.

Looking forward, we believe that the overall climate for equity investors
generally will continue to be positive, although valuations are less attractive
than they were a year ago, and a correction after a period of strong
performance is possible. Rising yields have depressed year-to-date bond
returns, but increased the attractiveness of bonds looking forward.

Sudden swings in the markets are always to be expected. Just as staying
diversified and invested are important investment principles, it is also
important to pay attention to asset allocation. As always, we encourage
shareholders to work closely with their financial advisor to find the mix of
stocks, bonds and money market assets that is aligned to their particular risk
tolerance and investment objective.

Respectfully,

/s/ Daniel K. Kingsbury

Pioneer Cullen Value Fund
- --------------------------------------------------------------------------------
PORTFOLIO MANAGEMENT DISCUSSION 6/30/07
- --------------------------------------------------------------------------------

The U.S. stock market surged upward throughout the 12 months ending June 30,
2007, in a rally only briefly interrupted by short-lived corrections. Rising
corporate profits encouraged investors to bid up the prices of almost all
equities over the period. In the following interview, James P. Cullen discusses
the factors that influenced Pioneer Cullen Value Fund's performance during the
12 months. As President of Cullen Capital Management LLC, Mr. Cullen oversees
the team responsible for the daily management of the Fund.

Q:  How did the Fund perform during the 12 months ending June 30, 2007?

A:  Cullen Value Fund's Class A shares had a total return of 17.13% at net
    asset value for the 12 months ending June 30, 2007. During the same
    period, the Standard & Poor's 500 Index (the S&P 500) rose 20.59%. The
    average return of the 498 funds in Lipper's Large Cap Value category was
    20.81% for the 12 months.

    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:  What were the principal factors that influenced Fund performance during the
    12 months?

A:  Stock prices kept climbing through virtually the entire fiscal year. While
    there was some volatility along the way, the 12-month period was
    remarkably unusual in how greatly the number of positive days in the
    market outnumbered negative days. Such an environment isn't necessarily
    conducive to our style, as we focus on stocks with relatively low
    price-to-earnings ratios compared to the overall market, and we invest in
    companies with good long-term prospects. Because of our long-term focus,
    we usually do better during periods when stocks move both up and down,
    rather than in periods - such as the last 12 months - when momentum seems
    to be driving equity prices ever higher.

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

Q:  What were your principal strategies during the period?

A:  As stock prices kept rising, we began to see the market as overbought -
    influenced more by speculative behavior than economic fundamentals - and
    we became somewhat more conservative even as more speculative,
    smaller-company stocks became fashionable in the market. Among other
    things, we maintained an emphasis on financials and pharmaceutical stocks
    - two areas with defensive characteristics which underperformed the
    market during the persistent rally. We also had a large exposure to the
    consumer staples sector - another more defensive area. Within consumer
    staples, we held major positions in global companies such as Unilever,
    Nestle and Diageo. Our consumer staples weighting was more than twice
    that of the S&P 500 at the end of the period.

    We were underweighted in energy for the period, although we built up our
    position in the sector during the first half of 2007 by adding companies
    such as Devon Energy, an exploration and production company; Gazprom, the
    Russian energy giant; and ConocoPhillips, a major integrated oil and
    energy company. Overall, though, our de-emphasis on energy did not help
    performance during the period.

    In general, we made few major changes to the portfolio. For example, while
    we sold our position in Hartford Financial, we used the proceeds to
    initiate an investment in another insurance giant, American International
    Group (AIG), which we liked because of its exposure to international
    markets. While we reduced our position in financials stocks in 2006, we
    still maintained a focus on them, emphasizing the larger, diversified
    financial services corporations that have increased their profiles in
    international markets. Noteworthy examples include our holdings in shares
    of Morgan Stanley, Merrill Lynch and JP Morgan Chase. On June 30, 2007,
    our weighting in the financials sector accounted for approximately 23.5%
    of Fund assets, which was more than the weighting in the S&P 500. While we
    have maintained our general weighting in health care - less than that in
    the S&P 500 - we did make some minor adjustments. For example, in the
    pharmaceuticals area, while we sold our investment in Sanofi Aventis, we
    added a position in Wyeth. The decision was based on our belief that in an
    era

                                                                               5

PORTFOLIO MANAGEMENT DISCUSSION 6/30/07                            (continued)
- --------------------------------------------------------------------------------

    of industry consolidation, Wyeth is better positioned as a potential
    acquisition candidate.

Q:  What types of individual investments most affected results over the 12
    months?

A:  We had excellent performance from some of the mid-sized companies in our
    portfolio. For example, Borg-Warner, a manufacturer of highly engineered
    components, such as drive trains for the automotive industry, gained 39%
    and was among the top contributors to results. Other mid-sized companies,
    such as railroad corporation Canadian Pacific and technology manufacturer
    Arrow Electronics, also turned in excellent results.

    Other holdings that outperformed the market and added to the Fund's
    returns included: technology companies Hewlett-Packard and Nokia; consumer
    staples companies Unilever, Bunge, Diageo and Nestle; insurer MetLife; oil
    company ConocoPhillips; diversified industrial company 3M;
    telecommunication services providers Verizon and AT&T; and Cemex, the
    Mexican-based materials giant.

    After helping support performance in 2006, our exposure to the diversified
    financials industry was a drag on performance in 2007, as investors
    worried about the potential fallout from the problems in the subprime
    mortgage lending area. However, we continue to like the prospects of our
    financials holdings and have maintained our positions. Also holding back
    results was Regions Financial, a banking corporation based in the
    Southeast. Investors have been leery of acquisitions the company has made,
    but we think the corporation has sound prospects.

Q:  What is your investment outlook?

A:  We plan to continue to pursue our strategy, which is to buy higher-quality
    companies at inexpensive prices relative to our estimate of long-term
    prospects. We continue to like the prospects of our consumer staples
    holdings - many of which have a major presence in the global marketplace.

    The recent advances in the stock market have been primarily liquidity
    driven. In other words, new money has entered the market, attracted by
    robust recent returns, and has driven up stock prices in general. As a
    consequence, many of the best

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

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

    performing stocks have been highly speculative. However, as corporate
    earnings growth slows, we think the stock market is likely to return to a
    more normal situation, creating conditions where the types of high-quality
    value stocks that we emphasize can do well. Many of our holdings boast
    high dividend yields, which also should be an advantage as the market
    enters a more uncertain period.

Investments in mid-sized companies may offer the potential for higher returns,
but are also subject to greater short-term price fluctuations than larger, more
established companies. The Fund invests in a limited number of securities and,
as a result, the Fund's performance may be more volatile than the performance
of other funds holding more securities. Investing in foreign and/or emerging
markets securities involves risks relating to interest rates, currency exchange
rates, economic, and political conditions. 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 and sectors.

The Standard & Poor's 500 Index is a commonly used measure of the broad U.S.
stock market. Index returns assume reinvestment of dividends and, unlike Fund
returns, do not reflect any fees, expenses or sales charges. You cannot invest
directly in an index.

The index defined here pertains to the "Value of $10,000 Investment" charts on
pages 10-14.

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.

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 information.

The performance table and graph do not reflect the deduction of fees and taxes
that a shareowner would pay on Fund distributions or the redemption of Fund
shares.

Pioneer Cullen Value Fund was created through the reorganization of the
predecessor Cullen Value Fund on 2/28/05. The performance of Class A shares of
the Fund from July 1, 2000 to February 25, 2005 is the performance of Cullen
Value Fund's single class, which has been restated to reflect differences in any
applicable sales charge, (but not other differences in expenses). If all
expenses of the Fund were reflected, the performance would be lower.

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.

The performance of Class R shares for the period prior to the commencement of
operations of Class R shares on November 1, 2006, is based on the performance
of the Fund's Class A shares, reduced to reflect the higher distribution and
service fees of Class R shares. For the period after November 1, 2006, the
actual performance of Class R shares is reflected. Class R 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.

The net expense ratio reflects contractual expense limitations currently in
effect through 11/1/07 for Class R Shares. There can be no assurance that
Pioneer will extend the expense limitations beyond such time. Please see the
prospectus and financial statements for more information.

The performance table and graph do not reflect the deduction of fees and taxes
that a shareowner would pay on Fund distributions or the redemption of Fund
shares.

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.

Performance for periods prior to the inception of Y shares reflects the NAV
performance of the Fund's A shares. The performance does not reflect differences
in expenses, including the Rule 12b-1 fees applicable to A shares. Since fees
for A shares are generally higher than those of Y shares, the performance shown
for Y shares prior to their inception would have been higher.

Class A shares are used as a proxy through February 28, 2005 the inception date
of Class Y shares.

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.

The performance table and graph do not reflect the deduction of fees and taxes
that a shareowner would pay on Fund distributions or the redemption of Fund
shares.

Pioneer Cullen Value Fund was created through the reorganization of the
predecessor Cullen Value Fund on 2/28/05. The performance of Class Y shares of
the Fund from July 1, 2000 to February 25, 2005 is the performance of Cullen
Value Fund's single class, which has not been restated to reflect any
differences in expenses. Cullen Value Fund had higher expenses than those of the
Fund's Class Y shares.

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.

     shares, respectively, multiplied by the average account value over the

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.

NOTES TO FINANCIAL STATEMENTS 6/30/07
- --------------------------------------------------------------------------------

1.   Organization and Significant Accounting Policies

Pioneer Cullen Value Fund (the Fund) is a diversified series of Pioneer Series
Trust III, a Delaware statutory trust registered under the Investment Company
Act of 1940 as an open-end management investment company. The investment
objective of the Fund is to seek capital appreciation. Current income is a
secondary objective.

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 on November 1, 2006.
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 the level of transfer agent and distribution fees may
differ among classes. Class A, Class B, Class C, and Class R shareowners have
exclusive voting rights with respect to the distribution plan for each class.
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.

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 and sectors. Information regarding the Fund's principal risks are
contained in the Fund's prospectus. Please refer to those documents when
considering the Fund's risks.

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 as of 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

                                                                              31


Pioneer Cullen Value Fund
- --------------------------------------------------------------------------------
NOTES TO FINANCIAL STATEMENTS 6/30/07                              (continued)
- --------------------------------------------------------------------------------

     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, 2007 there were no securities fair valued. Temporary cash
     investments are valued at cost which approximates market value.

     Dividend income is recorded on the ex-dividend date except that certain
     dividends from foreign securities where the ex-dividend date may have
     passed are recorded as soon as the Fund becomes aware of the ex-dividend
     data in exercise of reasonable diligence. Dividend and interest income is
     recorded on the accrual basis, net of unrecoverable foreign taxes withheld
     at the applicable country rates.

     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 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,
     2007 and June 30, 2006 were as follows:

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


     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 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 approximately $278,292 in underwriting
     commissions on the sale of Class A shares during the year ended June 30,
     2007.

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 (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

                                                                              33

     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 each class 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, on the same day, 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 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
     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

2.   Management Agreement

PIM, a wholly owned indirect subsidiary of UniCredito Italiano, manages the
Fund's portfolio. PIM receives a basic fee that is calculated at the annual rate
of 0.70% of the Fund's average daily net assets up to $1 billion, 0.65% of the
next $1 billion, 0.60% of the next $1 billion, and 0.55% of assets over $3
billion. For the year ended June 30, 2007, the net management fee was equivalent
to 0.66% of average daily net assets.

PIM, and not the Fund, pays a portion of the fee it receives from the Fund to
Cullen LLC as compensation for Cullen's subadvisory services to the Fund.

Through November 1, 2009 PIM has agreed not to impose all or a portion of its
management fee and to assume other operating expenses of the Fund to the extent
necessary to limit Class A expenses to 1.25% of the average daily net assets
attributable to Class A shares. Through November 1, 2007, PIM has agreed not to
impose all or a portion of its management fee and to assume other operating
expenses of the Fund to the extent necessary to limit Class B and Class C
expenses to 2.15% of the average daily net assets attributable to Class B and
Class C shares, respectively.

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, 2007, $113,771 was payable to PIM
related to management fees, administrative costs and certain others 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 are $312,346 in transfer agent
fees payable to PIMSS at June 30, 2007.

                                                                              35

4.   Distribution and Service Plans

The Fund adopted a Plan of Distribution with respect to Class A, Class B, Class
C, and Class R shares 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. This fee consists of a 0.25% service fee
and a 0.75% distribution fee both 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 net average daily net assets attributable to Class R shares as
compensation for distribution services. 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 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. Included in due to affiliates is $62,272 in distribution fees payable to
PFD at June 30, 2007.

In addition, redemptions of each class of shares (except Class R and 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 that are redeemed
within five 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 were subject to a CDSC
of 1.00%. There is no CDSC for Class R and Class Y shares. Proceeds from the
CDSCs are paid to PFD. For the year ended June 30, 2007, CDSCs in the amount of
$372,482 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, 2007, the Fund's expenses were reduced by $87,527 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 $200 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 $200 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
June 30, 2007, the Fund had no borrowings under this agreement.

7.   New Pronouncements

On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48). FIN
48 provides guidance for how uncertain tax positions should be recognized,
measured, presented and disclosed in the financial statements. FIN 48 requires
the evaluation of tax positions taken or expected to be taken in the course of
preparing the Fund's tax returns to determine whether the tax positions have a
"more-likely-than-not" probability of being sustained by the applicable tax
authority. Tax positions deemed to not meet the more-likely-than-not threshold
would be recorded as a tax benefit or expense in the reporting period in which
they are realized. Adoption of FIN 48 is required for fiscal years beginning
after December 15, 2006 and is to be applied to all open tax years as of no
later than June 30, 2008. At this time, management is evaluating the
implications of FIN 48 and any impact in the financial statements has not yet
been determined.

In addition, in September 2006, Statement of Financial Accounting Standards No.
157, Fair Value Measurements (SFAS 157), was issued and is effective for fiscal
years beginning after November 15, 2007. SFAS 157 defines fair value,
establishes a framework for measuring fair value and expands disclosures about
fair value measurements. Management is currently evaluating the impact the
adoption of SFAS 157 will have on the Fund's financial statement disclosures.

                                                                              37

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

To the Board of Trustees and Shareowners of Pioneer Cullen Value Fund:

We have audited the accompanying statement of assets and liabilities of Pioneer
Cullen Value Fund (the "Fund"), including the schedule of investments, as of
June 30, 2007, 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
therein. 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, 2004 were audited by other auditors whose report, dated August 9, 2004,
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 audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. We were
not engaged to perform an audit of the Fund's internal control over financial
reporting. Our audits included 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 confirmation of
securities owned as of June 30, 2007, 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 Cullen Value Fund at June 30, 2007, 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 therein, in conformity with U.S. generally accepted accounting
principles.

 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.

  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.

  services by service category, including fees, provided by the Audit firm as
  set forth in the above policy.

provided to an affiliate that required the Fund's audit
committee pre-approval.

control with the investment adviser that provides ongoing services to the
