Dear Shareowner,
- --------------------------------------------------------------------------------

We are pleased to present the first shareholder report for Pioneer Global
Aggregate Bond Fund. The Fund, introduced to investors on December 28, 2007,
offers investors the opportunity to receive current income from a prudently
managed portfolio of investment-grade, fixed-income securities from the world's
industrialized nations. The Fund draws upon Pioneer's international reach as
well as its demonstrated expertise in investing in fixed-income markets around
the globe.

The experiences in the world's capital markets during the first four months of
2008 reinforce the importance of two general investment themes: stay diversified
and keep your portfolio invested in the markets. These are principles that have
served investors well over time. They are particularly useful guides to keep in
mind today, at a time when markets around the globe are being buffeted by
problems in the financial and real estate industries and by concerns about a
slowing economy.

After an extended period of steady economic growth with sustained low
unemployment and low inflation, the U.S. economy ran into difficulty as 2007
drew to a close. Investors in subprime mortgages were forced to mark down the
value of their assets, imperiling leveraged balance sheets. The ensuing credit
crunch forced central banks in the United States and Europe to assume the role
of "lender of last resort" to keep credit markets functioning. Conditions
worsened in the first quarter of 2008, as falling prices, margin calls and
deleveraging continued, the auction rate preferred market seized up. The U.S.
Federal Reserve expanded its lender-of-last-resort role to include lending to
primary dealers and continued to cut interest rates. By then, recession talk was
widespread as concern grew that falling home prices, rising unemployment,
sharply rising food and energy prices, and disruptions in financial markets
posed a significant threat to economic growth.

Markets reacted poorly to the developments leading up to the problems at Bear
Stearns, with fixed-income credit spreads (the difference in rates between
corporate and U.S. government bonds) widening dramatically and stock markets
declining, wiping out the positive returns markets had delivered in the
preceding calendar year. Treasury bond prices rose as the market underwent a
flight to quality. In the six weeks between the near failure of Bear Stearns and
the end of April, though, there were no further market crises, recession fears
faded in light of positive economic news, and stock markets rallied, recouping
some of their first-quarter losses, while Treasury bond prices fell back.

Over the four months ending April 30, 2008, the U.S. investment-grade bond
market, as measured by the Lehman Brothers Aggregate Bond Index,

Letter

rose 1.95%. Over the same period, the Lehman Brothers Global Aggregate Bond, a
reflection of investment-grade bond performance throughout the world, gained
4.60%. The U.S. high-yield bond market, as measured by the Merrill Lynch High
Yield Bond Master II Index, rose 1% over the four months ending April 30, 2008.
Also during the period, the Merrill Lynch Global High Yield and Emerging Markets
Plus Index, which reflects the performance of high-yield corporate bonds and
emerging market securities globally, gained 1.73%.

Looking forward, the risk of a 2008 recession seems diminished, but substantial
risks remain in both financial markets and the real economy. On the other hand,
a weak U.S. dollar and substantial fiscal and monetary stimulus are potent
support for the economy. Markets remain volatile, and falling risk tolerances
and deleveraging may depress asset prices in the short term, but equity and
corporate bond valuations look attractive over a longer time horizon unless the
U.S. economy falls into a severe and protracted recession.

Sudden swings in the markets are always to be expected, but they are difficult
to time. Maintaining a long-term time horizon, being diversified, and paying
attention to asset allocation are important investment principles. As always, we
encourage you to work closely with your financial advisor to find the mix of
stocks, bonds and money market assets that is best aligned to your particular
risk tolerance and investment objective and to adhere to a strategic plan rather
than letting emotion drive investment decisions.

Respectfully,

[Signature of Daniel K. Kingsbury]

Daniel K. Kingsbury, President and CEO
Pioneer Investment Management USA Inc.

PORTFOLIO MANAGEMENT DISCUSSION 4/30/08
- --------------------------------------------------------------------------------

Investors in fixed-income markets throughout the world sought out higher-quality
investments, most notably sovereign government bonds, against a backdrop of
widespread fears about credit risk during the first four months of 2008.
Investment-grade corporate securities trailed the performance of government
bonds, especially in the first three months of the year, as the yield spreads
between high-grade and lower-rated securities widened. The following is an
interview with Charles Melchreit, a member of the team that managed Pioneer
Global Aggregate Bond Fund from its inception on December 28, 2007, through the
end of the Fund's first reporting period on April 30, 2008.

Q:   How did the Fund perform since the start of its operations on December 28,
     2007, through April 30, 2008?

A:   Pioneer Global Aggregate Bond Fund's Class A shares had a total return of
     4.02% at net asset value during the period, while during the same period
     the Lehman Global Aggregate Bond Index returned 4.60% and the Lehman
     Aggregate Bond Index rose by 1.95%. During the first four months of 2008,
     the average return of the 125 mutual funds in Lipper's Global Income
     category was 2.55%. On April 30, 2008, the Fund's 30-day SEC yield for
     Class A shares was 2.71%.

     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 main factors affecting performance during the four-month
     period ended April 30, 2008?

A:   In a challenging global investment environment, our focus on the sovereign
     debt in Europe and U.S. government agencies helped the Fund hold up well
     against a volatile backdrop. The Fund began investing in the midst of a
     global credit crisis. The turmoil that began with concerns about U.S.
     subprime mortgage problems created a loss of financial liquidity in credit
     markets generally, causing a drying up of money available for lending.
     Banks in Europe and Japan as well as in the United States announced
     significant losses as they reported massive write-downs in the

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

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

     values of subprime-related loans carried on their balance sheets. The
     turmoil in the financials sector raised concerns about the sustainability
     of economic growth trends, most notably in the United States, the United
     Kingdom and Europe. The U.S. economy showed the greatest weakness, while
     the strength of foreign markets helped sustain strong global growth trends
     overall.

     In this environment, credit spreads widened, indicating the growing yield
     differences between high-quality and lower-quality debt, with the
     highest-quality securities turning in the best relative results.
     Investment-grade corporate bonds were among the groups affected adversely,
     while U.S. Treasuries, government-backed mortgages and sovereign government
     bonds performed relatively well.

Q:   What were your principal strategies in this environment?

A:   Pioneer Global Aggregate Bond Fund is designed to invest in high-quality
     debt securities, focused on opportunities in developed, industrialized
     economies. The Fund emphasizes investments in investment-grade corporate
     bonds, government-agency securities and the sovereign debt of governments
     of industrialized nations. As we began investing, the market offered little
     incentive to move outside this principal investment universe and the Fund
     avoided investing in emerging markets. The Fund saw the greatest
     opportunities in the United States, where asset values in corporate bonds
     and mortgage-backed securities had fallen to relatively attractive levels
     as a result of the credit crisis. We invested in bonds of financials and
     industrial companies and both U.S. agency and non-agency mortgage-backed
     securities. Outside the United States, the Fund focused primarily in
     government bonds, investing in Europe, the United Kingdom and Japan. In
     Europe, the Fund were concerned about a slowing of the economy and
     downplayed corporate investments, although the Fund did invest selectively
     in some financials sector bonds that had been underperforming. However, in
     the United Kingdom, concerns about the health of the financials sector and
     weakness in housing caused the Fund largely to avoid investments in
     financials sector bonds.

     In the Fund's currency allocations, the Fund emphasized U.S. dollar-linked
     currencies, including those of the United States, Canada, Australia and New
     Zealand. Together, they constituted approximately 55% of the Fund's assets
     at the end of the period on April 30,


                                                                               5

     2008. The Fund was underweighted in both the euro and euro-bloc currencies
     as well as the British pound sterling. Relative to the Lehman Global
     Aggregate Bond Index, the Fund was significantly underweighted in the
     Japanese yen, primarily because of unattractive yields.

     At the end of the period, on April 30, 2008, 28.2% of the Fund's assets
     were invested in U.S. mortgage-backed securities, 14.4% were invested in
     investment-grade bonds in the United States, 9.2% were invested in U.S.
     Treasury and government agency bonds, and 12.3% were invested in cash and
     short-term equivalents. Approximately 34% of the Fund's assets were
     invested in developed markets, primarily in government securities. The Fund
     had minimal exposure to high-yield corporate bonds or emerging market debt.
     Average credit quality of the Fund's portfolio was AA, while the average
     maturity of the Fund's holdings was 6.3 years and average effective
     duration was 4.4 years.

Q:   What types of investments most influenced performance?

A:   Security selection in the United States and in Europe helped support
     results. The Fund's positions in European sovereign debt and in U.S.
     government agency mortgages proved to be particularly successful.

     Holding back results was the Fund's underweighting of the Japanese yen,
     which rallied against other currencies during the period. In addition, the
     relatively short duration of the Fund's portfolio in its investments in the
     United States held back relative results, as intermediate-term securities
     outperformed as interest rates declined.

Q:   What is your investment outlook?

A:   We believe attractive value still exists in the United States, particularly
     in investment-grade corporates. The valuations of many bonds have been
     beaten down by the negative environment for credit-sensitive securities,
     especially in relation to our outlook for the overall economy. We think
     that while the economy is slowing, we are not likely to see a severe
     recession. Banks, with the help of the monetary stimulus supplied by the
     Federal Reserve, should be able to repair the damage to their balance
     sheets caused by the credit crisis. Despite weakness in housing and the
     financials

     sector, we think the economy should be able to hold up, growing slowly this
     year and then accelerating in 2009.

     In the near term, we think the U.S. dollar may appreciate against foreign
     currencies, especially the British pound sterling and eurozone currencies.
     We anticipate holding investments with a longer duration in the Europe and
     in the United Kingdom, as we think their central banks are likely to lower
     short-term rates in the coming months. We also expect to maintain
     investments with longer durations within the United States, which should be
     beneficial if market interest rates decline and prices rise.

Investments in high-yield or lower-rated securities are subject to
greater-than-average risk. When interest rates rise, the prices of fixed-income
securities in the Fund will generally fall. Conversely, when interest rates
fall, the prices of fixed-income securities in the Fund will generally rise.
Investing in foreign and/or emerging markets securities involves risks relating
to interest rates, currency exchange rates, economic, and political conditions.
Investments in the Fund are subject to possible loss due to the financial
failure of underlying securities and their inability to meet their debt
obligations. Prepayment risk is the chance that mortgage-backed bonds will be
paid off early if falling interest rates prompt homeowners to refinance their
mortgages. Forced to reinvest the unanticipated proceeds at lower interest
rates, the Fund would experience a decline in income and lose the opportunity
for additional price appreciation associated with falling interest rates. The
Fund can invest 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. 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. These risks may increase share
price volatility.

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

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 charges been reflected. POP returns reflect deduction
of maximum 4.5% 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 net expense ratio reflects contractual expense limitations currently in
effect through 3/1/11 for Class A 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.

Class C shares held for less than one year are also subject to a 1% contingent
deferred sales charge (CDSC). The performance of Class C shares 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 asset value per share. Returns would
have been lower had sales charges been reflected. All results are historical and

COMPARING ONGOING FUND EXPENSES 4/30/08
- --------------------------------------------------------------------------------

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.

     and 0.89% for Class A, Class C, and Class Y respectively, multiplied by the
     average account value over the period, multiplied by 125/366 (to reflect
     the partial year period)


                                                                              13

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 4/30/08 (unaudited)
- --------------------------------------------------------------------------------

1. Organization and Significant Accounting Policies

Pioneer Global Aggregate Bond Fund (the Fund) is a series of Pioneer Series
Trust VII, 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 maximize total return through a
combination of income and capital appreciation.

The Fund offers three classes of shares - Class A, Class C, and Class Y shares.
Class A, Class C, and Class Y shares were first publicly offered on December 28,
2007. 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 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 gain or loss 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. The Fund's investments in foreign markets and countries
with limited developing markets may subject the Fund to a greater degree of risk
than in a developed market. These risks include disruptive political or economic
conditions and the imposition of adverse governmental laws or currency exchange
restrictions. The Fund's prospectuses contain information regarding the Fund's
principal risks. 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


                                                                              33


Pioneer Global Aggregate Bond Fund

- --------------------------------------------------------------------------------
NOTES TO FINANCIAL STATEMENTS 4/30/08 (unaudited)                    (continued)
- --------------------------------------------------------------------------------

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 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. Fixed income securities
     with remaining maturity of more than 60 days are valued at prices supplied
     by independent pricing services, which consider such factors as Treasury
     spreads, yields, maturities and ratings. Valuations may be supplemented by
     dealers and other sources, as required. Securities for which there are no
     other readily available valuation methods are valued using fair value
     methods pursuant to procedures adopted by the Board of Trustees. At April
     30, 2008 there were no securities that were valued using fair value
     methods. Temporary cash investments are valued at cost which approximates
     market value.

     All discounts and premiums on debt securities are accreted or amortized
     daily, respectively, on a yield-to-maturity basis into interest income with
     a corresponding increase or decrease in the cost basis of the security.
     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.

     The Fund invests in below investment grade (high yield) debt securities and
     preferred stocks. Some of these high yield securities may be convertible
     into equity securities of the issuer. Debt securities rated below
     investment grade are commonly referred to as "junk bonds" and are
     considered speculative. These securities involve greater risk of loss, are
     subject to greater price volatility, and are less liquid, especially during
     periods of economic uncertainty or change, than higher rated debt
     securities.

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

B.   Foreign Currency Translation

     The books and records of the Fund are maintained in U.S. dollars. Amounts
     denominated in foreign currencies are translated into U.S. dollars using
     current exchange rates.

     Net realized gains and losses on foreign currency transactions, if any,
     represent, among other things, the net realized gains and losses on foreign
     currency contracts, disposition of foreign currencies and the difference
     between the amount of income accrued and the U.S. dollars actually
     received. Further, the effects of changes in foreign currency exchange
     rates on investments are not segregated in the statement of operations from
     the effects of changes in market price of those securities but are included
     with the net realized and unrealized gain or loss on investments.

C.   Forward Foreign Currency Contracts

     The Fund enters into forward foreign currency contracts (contracts) for the
     purchase or sale of a specific foreign currency at a fixed price on a
     future date as a hedge or cross-hedge against either specific investment
     transactions (settlement hedges) or portfolio positions (portfolio hedges).
     All contracts are marked to market daily at the applicable exchange rates,
     and any resulting unrealized gains or losses are recorded in the Fund's
     financial statements. The Fund records realized gains and losses at the
     time a portfolio hedge is offset by entry into a closing transaction or
     extinguished by delivery of the currency. Risks may arise upon entering
     into these contracts from the potential inability of counterparties to meet
     the terms of the contract and from unanticipated movements in the value of
     foreign currencies relative to the U.S. dollar. (See Note 6)

D.   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


                                                                              35


Pioneer Global Aggregate Bond Fund

- --------------------------------------------------------------------------------
NOTES TO FINANCIAL STATEMENTS 4/30/08 (unaudited)                    (continued)
- --------------------------------------------------------------------------------

     distributions may be shown in the accompanying financial statements as from
     or in excess of net investment income or as from net realized gain on
     investment transactions, or as from paid-in capital, depending on the type
     of book/tax differences that may exist.

     The tax character of current year distributions paid will be determined at
     the end of the current fiscal year.

E.   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 no underwriting commissions on the sale of
     Class A shares during the period ended April 30, 2008.

F.   Class Allocations

     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.

     Distribution fees are calculated based on the average daily net asset value
     attributable to Class A and Class C of the Fund, respectively (see Note 4).
     Class Y shares are not subject to a distribution plan. Shareowners of each
     class participate in 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).

     The Fund declares as daily dividends substantially all of its net
     investment income. All dividends are paid on a monthly basis. Short-term
     capital gain distributions, if any, may be declared with the daily
     dividends. Distributions to shareowners are recorded as of the ex-dividend
     date. Distributions paid by the Fund with respect to each class of shares
     are calculated in the same manner, at the same time, and in the same
     amount, except that Class A, Class C and Class Y shares can bear different
     transfer agent and distribution expense rates.

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

G.   Securities Lending

     The Fund lends securities in its portfolio to certain broker-dealers or
     other institutional investors. When entering into a loan, the Fund receives
     collateral 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 which is required
     to be at least 102%, at all times, of the fair value of the securities
     loaned. The amount of collateral is required to be adjusted daily to
     reflect any price fluctuation in the value of the loaned securities. The
     Fund has the right under the lending agreement to recover the securities
     from the borrower on demand. The Fund invests cash collateral in cash
     equivalent investments.

2. Management Agreement

Pioneer Investment Management, Inc. (PIM), a wholly owned indirect subsidiary of
UniCredito Italiano, the Fund's investment adviser, manages the Fund's
portfolio. Management fees are calculated daily at the annual rate of 0.50% of
the Fund's average daily net assets.

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 the
Fund expenses to 1.00% and 1.90% of the average daily net assets attributable to
Class A and Class C shares, respectively. These expense limitations are in
effect through March 1, 2011 for Class A shares and through March 1, 2009 for
Class C shares.

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. Included in "Due to affiliates" reflected on the
Statement of Assets and Liabilities is $6 in management fees, administrative
costs and certain other services payable to PIM at April 30, 2008.

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" reflected


                                                                              37

- --------------------------------------------------------------------------------
NOTES TO FINANCIAL STATEMENTS 4/30/08 (unaudited)                    (continued)
- --------------------------------------------------------------------------------

on the Statement of Assets and Liabilities is $163 in transfer agent fees
payable from PIMSS at April 30, 2008.

4. Distribution Plan

The Fund adopted Plans of Distribution with respect to 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 Plan, the Fund pays PFD
0.25% of the average daily net assets attributable to Class A shares as
compensation for personal services and/or account maintenance services or
distribution services with regard to Class A shares. Pursuant to the Plan, the
Fund pays PFD 1.00% of the average daily net assets attributable to Class C
shares. The fee for Class C shares 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 C shares.
Included in "Due to affiliates" reflected on the Statement of Assets and
Liabilities is $113 in distribution fees payable to PFD at April 30, 2008.

In addition, redemptions of each class of shares (except Class Y) 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. Redemptions of Class C shares within one year of purchase
are subject to a CDSC of 1.00% based on the lower of cost or market value of
shares being redeemed. Proceeds from the CDSCs are paid to PFD. For the period
ended April 30, 2008, no CDSCs were paid to PFD.

5. Expense Offset Arrangements

The Fund has entered into certain expense offset arrangements with PIMSS
resulting in a reduction in the Fund's total expenses due to interest earned on
cash held by PIMSS. For the period ended April 30, 2008, the Fund's expenses
were not reduced under such arrangements.

6. Forward Foreign Currency Contracts

At April 30, 2008, the Fund had entered into various contracts that obligate the
Fund to deliver currencies at specified future dates. At the maturity of a
contract, the Fund must make delivery of the foreign currency. Alternatively,
prior to the settlement date of a portfolio hedge, the Fund may close out such
contracts by entering into an

7. New Pronouncements

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.

In March 2008, Statement of Financial Accounting Standards No. 161, Disclosures
about Derivative Instruments and Hedging Activities ("SFAS 161"), was issued and
is effective for fiscal years beginning after November 15, 2008. SFAS 161
requires enhanced disclosures about an entity's derivative and hedging
activities. Management is currently evaluating the impact the adoption of SFAS
161 will have on the Fund's financial statement disclosures.

Dear Shareowner,
- --------------------------------------------------------------------------------
Staying diversified and keeping your portfolio invested in the markets are two
general investment principles that have served investors well over time. They
are particularly useful guides to keep in mind today, at a time when markets
around the globe are being buffeted by problems in the financial and real
estate industries and by concerns about a slowing economy.

After an extended period of steady economic growth with sustained low
unemployment and low inflation, the U.S. economy ran into difficulty as 2007
drew to a close. Investors in subprime mortgages were forced to mark down the
value of their assets, imperiling leveraged balance sheets. The ensuing credit
crunch forced central banks in the United States and Europe to assume the role
of "lender of last resort" to keep credit markets functioning. Conditions
worsened in the first quarter of 2008, as falling prices, margin calls and
deleveraging continued, the auction-rate preferred market seized up. The U.S.
Federal Reserve expanded its lender-of-last-resort role to include lending to
primary dealers and continued to cut interest rates. By then, recession talk
was widespread as concern grew that falling home prices, rising unemployment,
sharply rising food and energy prices, and disruptions in financial markets
posed a significant threat to economic growth.

Markets reacted poorly to the developments leading up to the difficulties
surrounding Bear Stearns, with fixed-income credit spreads (the difference in
rates between corporate and U.S. government bonds) widening dramatically and
stock markets declining, wiping out the positive returns markets had delivered
in the preceding year. Treasury bond prices rose as the market underwent a
flight to quality. In the six weeks between the Bear Stearns problems and the
end of April, though, there were no further market crises, recession fears
faded in light of positive economic news, and stock markets rallied, recouping
some of their first-quarter losses, while Treasury bond prices fell back.

Over the six-month period ending April 30, 2008, the Dow Jones Industrial
Average fell 7%, the Standard & Poor's 500 Index fell 10% and the NASDAQ
Composite Index fell 16%. The MSCI EAFE Developed Market Index of international
stock markets fell 9%, and the MSCI Emerging Markets Index fell 10%. The U.S.
investment-grade bond market, as measured by the Lehman Brothers Aggregate Bond
Index, was a relatively solid performer over the six months, rising 4%. The
U.S. high-yield bond market, as measured by the Merrill Lynch High Yield Bond
Master II Index, fell 1% as its higher-coupon yields could not offset a fall in
bond prices triggered by widening credit spreads.

Letter

Looking forward, the risk of a 2008 recession seems diminished, but substantial
risks remain in both financial markets and the real economy. On the other hand,
a weak U.S. dollar and substantial fiscal and monetary stimulus should offer
more support for the economy. Markets remain volatile, and falling risk
tolerances and deleveraging may depress asset prices in the short term, but
equity and corporate bond valuations look attractive over a longer time horizon
unless the U.S. economy falls into a severe and protracted recession.

Sudden swings in the markets are always to be expected, but they are difficult
to time. Maintaining a long-term time horizon, being diversified, and paying
attention to asset allocation are important investment principles. As always,
we encourage you to work closely with your financial advisor to find the mix of
stocks, bonds and money market assets that is best aligned to your particular
risk tolerance and investment objective and to adhere to a strategic plan
rather than letting emotion drive investment decisions.

Respectfully,

/s/Daniel K. Kingsbury

Pioneer Global High Yield Fund
- --------------------------------------------------------------------------------
PORTFOLIO MANAGEMENT DISCUSSION 4/30/08
- --------------------------------------------------------------------------------

Lower-rated, high-yielding corporate bonds, both domestic and foreign, were
buffeted by the turmoil in capital markets during the six months ending April
30, 2008. Markets became increasingly volatile after a crisis that began in
domestic subprime mortgages subsequently spread through the credit market.
High-yield bonds staged a comeback in the final six weeks of the period,
however, following the intervention of the U.S. Federal Reserve to inject more
liquidity into financial markets and stabilize conditions. The following is an
interview with Andrew Feltus, leader of the team managing Pioneer Global High
Yield Fund. Mr. Feltus provides an update on the Fund and its investment
strategies during the six months.

Q:  How did the Fund perform during the six months ending April 30, 2008?

A:  Pioneer Global High Yield Fund's Class A shares had a total return of
    -2.77%, at net asset value, over the six months. During the same period, the
    Merrill Lynch High Yield Master II Index declined by -0.77%, while the
    Merrill Lynch Global High Yield and Emerging Markets Plus Index rose 0.39%.
    The average return of the 458 mutual funds in Lipper's High Current Yield
    category was -2.22%. On April 30, 2008, the Fund's 30-day SEC yield for
    Class A shares was 9.78%.

    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:  What was the investment environment like for high-yield bonds during the six
    months?

A:  Early in the period, high-yield bonds extended a comeback that began in
    October 2007 and continued through November, the period's first month, as we
    saw investors hoping for a stabilization following the sharp declines of the
    late summer and early fall. The declines were the result of problems
    originating in the U.S. subprime mortgage market that created fears about
    investment

    quality, undermining values of credit-sensitive fixed-income sectors
    generally. The October-November comeback proved to be short-lived,
    however, as major investment banks throughout the world reported
    significant losses related to their exposure to subprime mortgages late in
    2007. The announcements set the stage for rising concerns about credit
    quality in general, which led to significant underperformance by the most
    credit-sensitive parts of the fixed-income markets, including high-yield
    corporate bonds and asset-backed securities. In this period of uncertainty
    and growing market volatility, the U.S. Federal Reserve attempted to
    stabilize the markets by cutting the key Fed funds rate several times and
    initiating new policies intended to provide more money for lending
    activities. In a series of actions that started in September 2007 and
    continued through the end of April 2008, the Fed cut the Fed funds rate
    from 5.25% to 2.00%. In the final month, the Fed also helped arrange the
    rescue of the faltering investment bank Bear Stearns by JP Morgan Chase &
    Co. and opened up lending facilities to investment banks. The actions of
    the Federal Reserve led to a sharp comeback by higher yielding securities
    in the final six weeks of the period. As reflected by the Merrill Lynch
    High Yield Master II Index, the domestic high-yield bond market rose by
    about 6% in the final six weeks, although the revival was not enough to
    overcome the effects of losses in the middle of the six-month period.
    Foreign high-yield corporate bonds and emerging market debt generally
    performed in line with the domestic high-yield market during the six
    weeks, although higher-rated emerging market sovereign debt did somewhat
    better. Investments denominated in most foreign currencies also performed
    relatively well, as the U.S. dollar continued to weaken against most
    foreign currencies.

Q:  What were the principal factors that affected performance relative to the
    global high-yield market during the six months ending April 30, 2008?

A:  The Fund's emphasis on domestic high-yield bonds, which constituted 58.6% of
    assets at the end of the six months, tended to hold back results, as did our
    principal focus on corporate bonds, rather than sovereign debt, in emerging
    markets investments. On April 30, 2008, 27.2% of Fund assets were invested
    in emerging markets, mostly in corporate bonds. However, the Fund's exposure
    to securities denominated in other currencies tended to


                                                                               5

PORTFOLIO MANAGEMENT DISCUSSION 4/30/08                            (continued)

    help the Fund's results. We began the period with 9.4% of Fund assets
    invested in securities denominated in other currencies, but took profits
    during the six months and ended the period with a 7.9% foreign currency
    exposure.


    During a period in which the lowest-rated tiers of the high-yield
    universe, CCC and B, underperformed, our underexposure to CCC-rated
    securities helped somewhat, but that was offset by our emphasis on B-rated
    securities. While the Fund suffered no defaults, and we believe the Fund's
    high-yield holdings were fundamentally sound and justified our
    investments, the B-rated securities lagged because of the market's
    aversion to lower-rated securities. We continued to hold the investments
    based on our research of the underlying holdings and their potential to
    perform well over the longer term as market conditions stabilize. At the
    end of the fiscal period, the average credit rating of Fund holdings was
    B-.

Q:  What types of investments most influenced results during the six months
    ended April 30, 2008?

A:  The Fund's overweighted position in energy sector bonds among our domestic
    high-yield holdings helped results, as energy bonds generally performed very
    well amid rising oil and natural gas prices. While few individual
    lower-rated securities escaped the effects of the turmoil in credit markets,
    some individual holdings nevertheless did well. The holdings included bonds
    of Cell C, a South African telecommunications service company, and C&M
    Financial, a Korean cable communications corporation. Cell C reported
    improvement in its operations after earlier struggles, while both companies
    benefited from growing expectations that they might be acquired. In
    addition, bonds of TXU Energy, a Texas-based utility, rose during a period
    when utilities did well. The bonds were a result of a leveraged buyout
    during 2007. While leveraged buyouts generally fell out of favor, the strong
    asset values supporting TXU's bonds helped them outperform. Also supporting
    the Fund's results were investments in emerging market currencies,
    particularly Brazil and Colombia.

    Holding back results was the Fund's exposure to bank loans, which
    constituted about 6% of Fund assets at the end of the period. Bank loans
    tend to be a defensive area, because of their higher credit


6


Pioneer Global High Yield Fund
- --------------------------------------------------------------------------------

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

    quality. Nevertheless, bank loan investments underperformed high-yield
    bonds because of a loss of financial liquidity in the credit markets
    during the six months. In addition, because the interest rates of bank
    loans tend to be adjustable, loans become less appealing to investors as
    interest rates decline and the rates of the loans reset downward.

    Individual bond holdings that detracted from the Fund's results included
    those of Huawei-3Com, a China-based technology company, and Telesat
    Canada, a satellite communications corporation based in China. Both
    underperformed in the general market downturn. In addition, bonds of two
    ethanol producers, Aventine Renewables and Verasun Energy, declined as
    rising corn prices pressured their operating margins, even during a period
    of rising energy prices. Other investments that held back results included
    asset-backed securities of Dunkin' Donuts and Domino's Pizza, both of
    which lagged because of the secondary effects that the credit crisis had
    on asset-backed securities.

Q:  What is your investment outlook?

A:  Even after rallying in the final six weeks of the six-month period ended
    April 30, 2008, the valuations of domestic corporate high-yield bonds
    continue to appear attractive and high-yield bonds retain wide yield
    advantages over Treasuries. The fixed-income markets may be volatile in the
    weeks ahead, but we believe investors are well compensated for the credit
    risks of high yield bonds, especially domestic bonds. We also may consider
    selectively increasing the Fund's exposure to asset-backed securities and
    subprime-related securities if we see very attractive prices created by the
    extreme market fluctuations of the previous months.

    If forecasts for the U.S. economy become less pessimistic, we believe the
    U.S. dollar may show renewed strength and investments in the euro and
    other foreign currencies may be less rewarding. The emerging markets have
    outperformed developed markets by wide margins in recent years, and growth
    in emerging markets should continue to outpace developed markets. However,
    the valuations of emerging market bonds at the end of the period were not
    as attractive as they had been relative to other securities. We anticipate
    continuing to look for opportunities in emerging


                                                                               7

    markets, but we intend to be selective as we pick investments on
    case-by-case analysis.

Investments in high-yield or lower-rated securities are subject to
greater-than-average risk. When interest rates rise, the prices of fixed-income
securities in the Fund will generally fall. Conversely, when interest rates
fall, the prices of fixed-income securities in the Fund will generally rise.
Investing in foreign and/or emerging markets securities involves risks relating
to interest rates, currency exchange rates, economic, and political conditions.
Investments in the Fund are subject to possible loss due to the financial
failure of underlying securities and their inability to meet their debt
obligations. Prepayment risk is the chance that mortgage-backed bonds will be
paid off early if falling interest rates prompt homeowners to refinance their
mortgages. Forced to reinvest the unanticipated proceeds at lower interest
rates, the Fund would experience a decline in income and lose the opportunity
for additional price appreciation associated with falling interest rates. The
Fund can invest 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. 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. These risks may increase share
price volatility.

INDEX DEFINITION
- --------------------------------------------------------------------------------

   The Merrill Lynch (ML) Global High Yield and Emerging Markets Plus
   Index tracks the performance of the below and border-line investment-grade
   global debt markets denominated in the major developed market currencies.
   The index includes sovereign issuers rated BBB1 and lower along with
   corporate issuers rated BB1 and lower. There are no restrictions on issuer
   country of domicile. However, the bonds must be publicly issued in a
   developed market (i.e., investment-grade country). Index returns are
   calculated monthly, 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
   appearing on pages 11-15.

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 charges been reflected. POP returns reflect deduction
of maximum 4.5% 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 net expense ratio reflects contractual expense limitations currently in
effect through 3/1/11 for Class A 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.

The performance data quoted represents past performance, which is no guarantee

(CDSC). Effective December 1, 2004, the period during which a 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, please see the prospectus
for details. Note: Shares purchased prior to December 1, 2004 remain subject to
the CDSC in effect at the time you purchased those shares. For performance
information for shares purchased prior to December 1, 2004, please visit

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

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.

Class C shares held for less than one year are also subject to a 1% contingent
deferred sales charge (CDSC). The performance of Class C shares 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 asset value per share.
"If Redeemed" results reflect the deduction of 1% CDSC. Returns would have been
lower had sales charges been reflected. 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

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 the Fund's Class Y shares on
December 28, 2005 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 Class
Y shares prior to their inception on December 28, 2005 would have been higher.
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.

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 Class Z 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
Z shares, the performance shown for Class Z shares prior to their inception
July 6, 2007 would have been higher. Class Z 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.

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.

*   Expenses are equal to the Fund's annualized expense ratio of 1.10%, 1.90%,
    1.83%, 0.72%, and 0.74% multiplied by the average account value over the
    period, multiplied by 182/366 (to reflect the partial year 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 Global High Yield Fund (the Fund) is a series of Pioneer Series Trust
VII, 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 maximize total return through a
combination of income and capital appreciation.

The Fund offers five classes of shares - Class A, Class B, Class C, Class Y and
Class Z shares. Class Y shares were first publicly offered on December 28,
2005. Class Z shares were first publicly offered on July 6, 2007. 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 and Class Z shares.
Class B shares convert to Class A shares eight years after the date of
purchase.

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 gain or loss 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. The Fund's investments in foreign markets and countries
with limited developing markets may subject the Fund to a greater degree of
risk than in a developed market. These risks include disruptive political or
economic conditions and the imposition of adverse governmental laws or currency
exchange restrictions. The Fund's prospectuses contain information regarding
the Fund's principal risks. Please refer to those documents when considering
the Fund's risks.


                                                                              57

- --------------------------------------------------------------------------------
NOTES TO FINANCIAL STATEMENTS 4/30/08 (unaudited)                  (continued)
- --------------------------------------------------------------------------------

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 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. Fixed income
    securities with remaining maturity of more than 60 days are valued at
    prices supplied by independent pricing services, which consider such
    factors as Treasury spreads, yields, maturities and ratings. Valuations
    may be supplemented by dealers and other sources, as required. Securities
    for which there are no other readily available valuation methods are
    valued using fair value methods pursuant to procedures adopted by the
    Board of Trustees. At April 30, 2008 there were no securities that were
    valued using fair value methods. Temporary cash investments are valued at
    cost which approximates market value.

    All discounts and premiums on debt securities are accreted or amortized
    daily, respectively, on a yield-to-maturity basis into interest income
    with a corresponding increase or decrease in the cost basis of the
    security. 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.

    The Fund invests in below investment grade (high yield) debt securities
    and preferred stocks. Some of these high yield securities may be
    convertible into equity securities of the issuer. Debt securities rated
    below investment grade are commonly referred to as "junk bonds" and are
    considered speculative. These securities involve greater risk of loss, are
    subject to greater price volatility, and are less liquid, especially
    during periods of economic uncertainty or change, than higher rated debt
    securities. The Fund is not diversified, which means that it can invest a
    higher percentage of its


58


Pioneer Global High Yield Fund
- --------------------------------------------------------------------------------

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

    assets in any one issuer than a diversified fund. Being non-diversified
    may magnify the Fund's losses from adverse events affecting a particular
    issuer.

B.  Foreign Currency Translation

    The books and records of the Fund are maintained in U.S. dollars. Amounts
    denominated in foreign currencies are translated into U.S. dollars using
    current exchange rates.

    Net realized gains and losses on foreign currency transactions, if any,
    represent, among other things, the net realized gains and losses on
    foreign currency contracts, disposition of foreign currencies and the
    difference between the amount of income accrued and the U.S. dollars
    actually received. Further, the effects of changes in foreign currency
    exchange rates on investments are not segregated in the statement of
    operations from the effects of changes in market price of those securities
    but are included with the net realized and unrealized gain or loss on
    investments.

C.  Forward Foreign Currency Contracts

    The Fund enters into forward foreign currency contracts (contracts) for
    the purchase or sale of a specific foreign currency at a fixed price on a
    future date as a hedge or cross-hedge against either specific investment
    transactions (settlement hedges) or portfolio positions (portfolio
    hedges). All contracts are marked to market daily at the applicable
    exchange rates, and any resulting unrealized gains or losses are recorded
    in the Fund's financial statements. The Fund records realized gains and
    losses at the time a portfolio hedge is offset by entry into a closing
    transaction or extinguished by delivery of the currency. Risks may arise
    upon entering into these contracts from the potential inability of
    counterparties to meet the terms of the contract and from unanticipated
    movements in the value of foreign currencies relative to the U.S. dollar.
    (See Note 8)

D.  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. Tax years prior to 2004 are


                                                                              59


Pioneer Global High Yield Fund

NOTES TO FINANCIAL STATEMENTS 4/30/08 (unaudited)                  (continued)
- --------------------------------------------------------------------------------

    closed (not subject to examination by tax authorities) due to the statute
    of limitations; all other tax years remain open.

    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 from or in excess of
    net investment income or as from net realized gain on investment
    transactions, or as from paid-in capital, depending on the type of
    book/tax differences that may exist.

    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 October 31, 2007 was as follows:



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

    Total                                                         $136,602,475
                                                                  ============

    The following shows the components of distributable earnings on a federal
    income tax basis at October 31, 2007:



- --------------------------------------------------------------------------------
                                                                        2007
- --------------------------------------------------------------------------------
                                                                
  Undistributed ordinary income                                    $15,803,280

  Unrealized depreciation                                          (19,286,359)
                                                                   -----------
    Total                                                          $ 6,682,419
                                                                   ===========
- --------------------------------------------------------------------------------


    The difference between book-basis and tax-basis unrealized depreciation is
    attributable to the tax deferral of losses on wash sales, adjustments
    relating to catastrophe bonds, the mark to market of forward currency
    contracts and the tax basis adjustment on partnerships and credit default
    swaps.

E.  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 UniCredit S.p.A.
    (UniCredit), earned $374,185 in underwriting commissions on the sale of
    Class A shares during the six months ended April 30, 2008.

F.  Class Allocations

    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.

    Distribution fees are calculated based on the average daily net asset
    value attributable to Class A, Class B and Class C of the Fund,
    respectively (see Note 5). Class Y and Class Z shares are not subject to a
    distribution plan. Shareowners of each class participate in all expenses
    and fees paid to the transfer agent, Pioneer Investment Management
    Shareholder Services, Inc. (PIMSS), for its services, which are allocated
    based on the number of accounts in each class and the ratable allocation
     of related out-of-pocket expenses (see Note 5).

    The Fund declares as daily dividends substantially all of its net
    investment income. All dividends are paid on a monthly basis. Short-term
    capital gain distributions, if any, may be declared with the daily
    dividends. Distributions to shareowners are recorded as of the ex-dividend
    date. Distributions paid by the Fund with respect to each class of shares
    are calculated in the same manner, at the same time, and in the same
    amount, except that Class A, Class B, Class C, Class Y and Class Z shares
    can bear different transfer agent and distribution expense rates.

G.  Repurchase Agreements

    With respect to repurchase agreements entered into by the Fund, the value
    of the underlying securities (collateral), including accrued interest
    received from counterparties, is required to be at least equal to or in
    excess of the value of the repurchase agreement at the time of purchase.
    The collateral for all repurchase agreements is held in safekeeping in the
    customer-only account of the Fund's


                                                                              61


Pioneer Global High Yield Fund

NOTES TO FINANCIAL STATEMENTS 4/30/08 (unaudited)                  (continued)
- --------------------------------------------------------------------------------

    custodian, or sub custodians. The Fund's investment adviser, Pioneer
    Investment Management, Inc. (PIM), is responsible for determining that the
    value of the collateral remains at least equal to the repurchase price.

H.  Securities Lending

    The Fund lends securities in its portfolio to certain broker-dealers or
    other institutional investors. When entering into a loan, the Fund
    receives collateral 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 which is
    required to be at least 102%, at all times, of the fair value of the
    securities loaned. The amount of collateral is required to be adjusted
    daily to reflect any price fluctuation in the value of the loaned
    securities. The Fund has the right under the lending agreement to recover
    the securities from the borrower on demand. The Fund invests cash
    collateral in cash equivalent investments.

I.  Credit Default Swap Agreements

    A credit default swap is a contract between a buyer of protection and a
    seller of protection against a pre-defined credit event. The Fund may buy
    or sell credit default swap contracts to increase the Fund's income, to
    add leverage to the Fund or to hedge the risk of default on portfolio
    securities. As a seller of protection, the Fund would be required to pay
    the notional (or other agreed-upon) value of the referenced debt
    obligation to the counterparty in the event of a default by a U.S. or
    foreign corporate issuer of a debt obligation, which would likely result
    in a loss to the Fund. In return, the Fund would receive from the
    counterparty a periodic stream of payments during the term of the contract
    provided that no event of default occurred. The maximum exposure of loss
    to the seller would be the notional value of the credit default swaps
    outstanding. If no default occurs, the Fund would keep the stream of
    payments and would have no payment obligation. The Fund may also buy
    credit default swap contracts in order to hedge against the risk of
    default of debt securities, in which case the Fund would function as the
    counterparty referenced above.


62


Pioneer Global High Yield Fund
- --------------------------------------------------------------------------------

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

    When the Fund enters into a credit default swap contract, one party, the
    protection buyer, makes an upfront or periodic payment to the protection
    seller in exchange for the right to receive a contingent payment. An
    upfront payment received by the Fund, as the protection seller, is
    recorded as a liability in the Fund's records. An upfront payment made by
    the Fund, as the protection buyer, is recorded as an asset in the Fund's
    records. Periodic payments received or paid by the Fund are recorded as
    realized gains or losses.

    The credit default swap contracts are marked-to-market daily using
    valuations supplied by independent sources and the change in value, if
    any, is recorded as unrealized gain or loss. Payments received or made as
    a result of a credit event or upon termination of the contract are
    recognized, net of the appropriate amount of the upfront payment, as
    realized gains or losses.

    Credit default swap contracts involving the sale of protection may involve
    greater risks than if the Fund had invested in the referenced debt
    instrument directly. Credit default swap contracts are subject to general
    market risk, liquidity risk, counterparty risk and credit risk. If the
    Fund is a protection buyer and no credit event occurs, it will lose its
    investment. If the Fund is a protection seller and a credit event occurs,
    the value of the referenced debt instrument received by the Fund, together
    with the periodic payments received, may be less than the amount the Fund
    pays to the protection buyer, resulting in a loss to the Fund.

    There were no credit default swap contracts outstanding at April 30, 2008.

Valuation

    Credit default swaps are valued by an independent pricing service based
    upon valuation models incorporating default probabilities, estimated
    recovery rates, actual reported transactions, and other available market
    data.

2. Unfunded Loan Commitments

As of April 30, 2008, the Fund had unfunded loan commitments of approximately
$481,643 (excluding unrealized depreciation on those commitments of $19,318 as
of April 30, 2008) which could be


                                                                              63

3. Management Agreement

Pioneer Investment Management, Inc. (PIM), a wholly owned indirect subsidiary

Management fees are calculated daily at the annual rate of 0.70% of the Fund's
average daily net assets up to $500 million; 0.65% of the next $500 million;
and 0.60% of the excess over $1 billion. Effective January 1, 2007, Pioneer's
fee is subject to an additional breakpoint. The Fund pays Pioneer a fee at the
annual rate of 0.55% of the Fund's average daily net assets greater than $1.5
billion. For the six months ended April 30, 2008, the net management fee was
equivalent to 0.63% of the average daily net assets.

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
the Fund expenses to 1.10%, 2.00% and 2.00% of the average daily net assets
attributable to Class A, Class B and Class C shares, respectively. These
expense limitations are in effect through March 1, 2011 for Class A shares and
through March 1, 2009 for Class B and Class C shares. Pioneer has contractually
agreed to limit ordinary operating expenses to the extent required to reduce
Fund expenses to 0.90% of the average daily net assets attributable to Class Z
shares. This expense limitation is in effect through March 1, 2011 for Class Z
shares.

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. Included in "Due to affiliates" reflected on
the Statement of Assets and Liabilities is $35,460 in management fees,
administrative costs and certain other services payable to PIM at April 30,
2008.

4. Transfer Agent

PIMSS, a wholly owned indirect subsidiary of UniCredit, provides substantially
all transfer agent and shareowner services to the Fund at negotiated rates.
Included in "Due to affiliates" reflected on the Statement of Assets and
Liabilities is $213,881 in transfer agent fees receivable from PIMSS at April
30, 2008.

5. Distribution Plan

The Fund adopted Plans of Distribution with respect to 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 Plan, the Fund pays PFD
0.25% of the average daily net assets attributable to Class A shares as
compensation for personal services and/or account maintenance services or
distribution services with regard to Class A Shares. Pursuant to the Plan, the
Fund pays PFD 1.00% of the average daily net assets attributable to Class B and
Class C shares. The fee for Class B and Class C shares 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. For the period from November 1, 2007
through January 31, 2008, PFD was reimbursed under the Plan of Distribution for
distribution expenses in an amount of up to 0.25% of the average daily net
assets attributable to Class A shares. Included in "Due to affiliates"
reflected on the Statement of Assets and Liabilities is $26,801 in distribution
fees payable to PFD at April 30, 2008.

In addition, redemptions of each class of shares (except Class Y and Class Z
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 are subject
to a CDSC of 1.00% based on the lower of cost or market value of shares being
redeemed. Proceeds from the CDSCs are paid to PFD. For the six months ended
April 30, 2008, CDSCs in the amount of $344,619 were paid to PFD.


                                                                              65

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 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
April 30, 2008, the Fund had no borrowings under this agreement.

7. Expense Offset Arrangements

The Fund has entered into certain expense offset arrangements with PIMSS
resulting in a reduction in the Fund's total expenses due to interest earned on
cash held by PIMSS. For the six months ended April 30, 2008, the Fund's
expenses were reduced by $32,974 under such arrangements.

8. Forward Foreign Currency Contracts

At April 30, 2008, the Fund had entered into various contracts that obligate
the Fund to deliver currencies at specified future dates. At the maturity of a
contract, the Fund must make delivery of the foreign currency. Alternatively,
prior to the settlement date of a portfolio hedge, the Fund may close out such
contracts by entering into an offsetting hedge contract. Open Portfolio hedges
at April 30, 2008 were as follows:

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


At April 30, 2008, the Fund had no outstanding settlement hedges.

9. New Pronouncements

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.

Pioneer Global High Yield Fund
- --------------------------------------------------------------------------------

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

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.

In March 2008, Statement of Financial Accounting Standards No. 161, Disclosures
about Derivative Instruments and Hedging Activities ("SFAS 161"), was issued
and is effective for fiscal years beginning after November 15, 2008. SFAS 161
requires enhanced disclosures about an entity's derivative and hedging
activities. Management is currently evaluating the impact the adoption of SFAS
161 will have on the Fund's financial statement disclosures.


                                                                              67

APPROVAL OF INVESTMENT ADVISORY AGREEMENT
- --------------------------------------------------------------------------------

Pioneer Investment Management, Inc. (PIM) serves as the Fund's investment
adviser pursuant to an investment advisory agreement between PIM and the Fund.
The Trustees of the Fund, as required by law, determine annually whether to
continue the investment advisory agreement for the Fund.

In connection with their most recent consideration of the investment advisory
agreement for the Fund, the Trustees received and reviewed a substantial amount
of information provided by PIM in response to requests of the independent
Trustees and their independent legal counsel. The independent Trustees met on a
number of occasions with PIM and also separately with their independent legal
counsel to evaluate and discuss the information provided to them by PIM. At a
meeting held on November 13, 2007, based on their evaluation of the information
provided by PIM, the Trustees, including the independent Trustees voting
separately, unanimously approved the continuation of the investment advisory
agreement for another year.

In considering the continuation of the investment advisory agreement, the
Trustees considered various factors that they determined were relevant,
including the factors described below. The Trustees did not identify any single
factor as the controlling factor in determining to approve the continuation of
the agreement.

Nature, Extent and Quality of Services
The Trustees considered the nature, extent and quality of the services provided
by PIM to the Fund, taking into account the investment objective and strategy
of the Fund and the information related to the Fund provided to the Trustees at
each quarterly meeting. The Trustees reviewed the terms of the investment
advisory agreement. The Trustees also reviewed PIM's investment approach for
the Fund and its research process. The Trustees considered the resources of PIM
and the personnel of PIM who provide investment management services to the
Fund. They also considered PIM's compliance and legal resources and personnel.

In addition, the Trustees considered the other services that PIM provides to
the Fund under the investment advisory agreement and that, as administrator,
PIM is responsible for the administration of the Fund's business and other
affairs. It was noted that PIM supervises and monitors the performance of the
Fund's service providers and provides the Fund with personnel (including
officers) as are necessary


68


Pioneer Global High Yield Fund
- --------------------------------------------------------------------------------

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

for the Fund's operations. The Trustees considered the fees paid to PIM for the
provision of such services.

Based on these considerations, the Trustees concluded that the nature, extent
and quality of services provided by PIM to the Fund were satisfactory and
consistent with the terms of the investment advisory agreement.

Performance of the Fund
The Trustees considered the performance results of the Fund over various time
periods. They reviewed information comparing the Fund's performance with the
average performance of its peer group of funds as classified by Morningstar,
Inc. (Morningstar), an independent provider of investment company data, and
with the performance of the Fund's benchmark index. The Trustees considered
that the Fund's annualized total return was in the first quintile of its
Morningstar category for the one, three and five year periods ended June 30,
2007. (In all quintile rankings referred to throughout this disclosure, first
quintile is most favorable to the Fund's shareowners. Thus, highest relative
performance would be first quintile and lowest relative expenses would also be
first quintile.) The Trustees concluded that the investment performance of the
Fund was satisfactory.

Management Fee and Expenses
The Trustees considered information on the fees and expenses of the Fund in
comparison to the management fees of its peer group of funds as classified by
Morningstar and the expense ratios of a peer group of funds selected on the
basis of criteria determined by the independent Trustees for this purpose using
data provided by Strategic Insight Mutual Fund Research and Consulting, LLC
(Strategic Insight), an independent third party.

The Trustees considered that the Fund's management fee for the twelve months
ended June 30, 2007 was in the fourth quintile relative to the management fees
paid by other funds in its peer group Morningstar category for the comparable
period. The Trustees also considered that the Fund's expense ratio for the
twelve months ended June 30, 2007 was in the fourth quintile relative to its
Strategic Insight peer group. The Trustee noted that the Fund's management fee
recently was lowered and that the impact of the lower management fee was not
fully reflected in the data. They also considered PIM's agreement to add a
breakpoint to the management fee schedule as described below.


                                                                              69


Pioneer Global High Yield Fund
- --------------------------------------------------------------------------------
APPROVAL OF INVESTMENT ADVISORY AGREEMENT                          (continued)
- --------------------------------------------------------------------------------

The Trustees also reviewed management fees charged by PIM to its separate
account clients with a similar investment strategy as the Fund. The Trustees
noted that in some instances the fee rates for those separate accounts were
lower than the management fees for the Fund and considered that, under the
investment advisory agreement with the Fund, PIM performs additional services
for the Fund that it does not provide to those other clients, including
oversight of the Fund's other service providers, regulatory compliance and
other services.

The Trustees concluded that the management fee payable by the Fund to PIM was
reasonable in relation to the nature and quality of services provided, taking
into account the fees charged by other advisers for managing comparable mutual
funds with similar strategies. The Trustees also concluded that the Fund's
expense ratio was reasonable, taking into account the size of the Fund, the
quality of services provided by PIM, the investment performance of the Fund and
the contractual expense limitation agreed to by PIM with respect to the Fund.

Profitability
The Trustees considered information provided by PIM regarding the profitability
of PIM with respect to the advisory services provided by PIM to the Fund,
including the methodology used by PIM in allocating certain of its costs to the
management of the Fund. The Trustees also considered PIM's profit margin in
connection with the overall operation of the Fund. They further reviewed the
financial results realized by PIM and its affiliates from non-fund businesses.
The Trustees considered PIM's profit margins with respect to the Fund in
comparison to the limited industry data available and noted that the
profitability of any adviser was affected by numerous factors, including its
organizational structure and method for allocating expenses. The Trustees
recognized that PIM should be entitled to earn a reasonable level of profit for
the services provided to the Fund. The Trustees concluded that PIM's
profitability with respect to the management of the Fund was not unreasonable.

Economies of Scale
The Trustees considered the economies of scale with respect to the management
of the Fund, whether the Fund had appropriately benefited from any economies of
scale, and whether there was potential for realization of any further economies
of scale. The


70


Pioneer Global High Yield Fund
- --------------------------------------------------------------------------------

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

Trustees considered PIM's agreement to add a breakpoint to the management fee
schedule so that the management fee would be reduced for Fund assets in excess
of $2 billion. The Trustees reviewed the impact that the breakpoint would have
on the Fund's management fee versus its Morningstar category peer group. The
Trustees concluded that, because of the addition of the breakpoint in the
management fee schedule and the reduced fee rate above certain asset levels,
any perceived or potential economies of scale would be shared between PIM and
the Fund.

Other Benefits
The Trustees considered the other benefits to PIM from its relationship with
the Fund. The Trustees considered that affiliates of PIM serve as the Fund's
transfer agent and distributor. The Trustees considered the receipt by PIM and
its affiliates of sales loads and payments under Rule 12b-1 plans in respect of
the Fund and the other Pioneer funds. The Trustees further considered the
intangible benefits to PIM by virtue of its relationship with the Fund and the
other Pioneer funds. The Trustees concluded that the receipt of these benefits
was reasonable in the context of the overall relationship between PIM and the
Fund.

Conclusion
After consideration of the factors described above as well as other factors,
the Trustees, including all of the independent Trustees, concluded that the
terms of the investment advisory agreement between PIM and the Fund, including
the fees payable thereunder, were fair and reasonable and voted to approve the
proposed continuation of the investment advisory agreement for the Fund.

                  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.

its definitive proxy statement, or this Item.


ITEM 11. CONTROLS AND PROCEDURES.

(a) Disclose the conclusions of the registrant's principal executive officer or
officers and principal financial officer or officers, or persons performing
similar functions, about the effectiveness of the registrant's disclosure
controls and procedures (as defined in Rule 30a-2(c) under the Act (17 CFR
270.30a-2(c))) based on their evaluation of these controls and procedures as of
a date within 90 days of the filing date of the report that includes the
disclosure required by this paragraph.

The registrant's principal executive officer
and principal financial officer have
concluded that the registrant's disclosure
controls and procedures are effective based
on their evaluation of these controls and
procedures as of a date within 90 days of the
filing date of this report.


(b) Disclose whether or not there were significant changes in the registrant's
internal controls or in other factors that could significantly affect these
controls subsequent to the date of their evaluation, including any corrective
actions with regard to significant deficiencies and material weaknesses.

There were no significant changes in the
registrant's internal control over financial
reporting that occurred during the second
fiscal quarter of the period covered by this
report that have materially affected, or are
reasonably likely to materially affect, the
registrant's internal control over financial
reporting.

The registrant's principal executive officer and principal financial
officer, however, voluntarily are reporting the following information:

In August of 2006 the registrant's investment adviser
enhanced its internal procedures for reporting performance
information required to be included in prospectuses.
Those enhancements involved additional internal controls
over the appropriateness of performance data
generated for this purpose.  Such enhancements were made
following an internal review which identified
prospectuses relating to certain classes of shares of
a limited number of registrants where, inadvertently,
performance information not reflecting the deduction of
applicable sales charges was included. Those prospectuses
were revised, and the revised prospectuses were distributed to
shareholders.


ITEM 12. EXHIBITS.

File the exhibits listed below as part of this Form. Letter or number the
exhibits in the sequence indicated.

(a) Any code of ethics, or amendment thereto, that is the subject of the
disclosure required by Item 2, to the extent that the registrant intends to
satisfy the Item 2 requirements through filing of an exhibit.



(b) A separate certification for each principal executive officer and principal
financial officer of the registrant as required by Rule 30a-2 under the Act
(17 CFR 270.30a-2).

Filed herewith.
