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
were particularly useful guides in recent months, when an otherwise healthy
long-term bull market was buffeted by problems in the mortgage and banking
industries.

Since mid-year 2007, issues tied to poor underwriting practices in the subprime
sector of the mortgage industry and to problems with risk management by banks
and hedge funds have resulted in increased market volatility and rising concern
about risks to U.S. economic growth.

U.S. economic growth had slowed over the past two years, but this has been due
as much to the natural maturation of the cyclical expansion, as U.S. factories
approached full utilization and the labor market approached full employment, as
to rising commodity prices or short-term interest rates. The slowdown was,
therefore, not entirely unwelcome, as it reduced the threat of higher
inflation. More recently, however, there has been increasing concern that
falling home prices, and/or disruptions in financial markets pose a larger
threat to continuing economic growth, and we have seen two cuts in short-term
interest rates from the Federal Reserve despite strong economic growth in the
second and third quarters of this year. A weaker U.S. dollar has put upward
pressure on some prices, but it has also significantly benefited exporters and
companies competing in the global marketplace, stimulating U.S. economic
growth.

Economic growth in the rest of the world remains relatively positive. In
Europe, solid GDP growth has driven unemployment lower and supported growing
consumption, although concerns about the impact of the strong Euro are a
persistent source of worry. Japanese economic growth continues, albeit at a
muted rate, and the country's deflationary problems are gradually receding.
Economic growth in emerging market countries remains faster than in the
developed world, led by China, which continues its rise as a world economic
power.

Looking forward, the economic outlook continues to appear generally positive,
although real estate prices, subprime mortgage defaults, and the possibility of
a liquidity/credit crunch represent growing sources of risk. Central banks have
responded to the stresses in the inter-bank and commercial paper markets by
acting as "lenders of last resort" and, in the case of the Federal Reserve, by
cutting rates.

The U.S. Federal Reserve and the world's other central banks continue to pursue
policies aimed at producing low and stable inflation, believed to be the best
backdrop for steady economic growth and low average unemployment over the long
term. Keeping inflation low is also an

important support for stock and bond valuations, and so central bank policies
have also been "investor friendly." We view the Fed's recent rate cuts as
temporarily "buying insurance" against a credit crunch, which would threaten
economic growth rather than as an abandonment of its commitment to keeping
inflation low.

Even against this "wall of worry" backdrop, the long-term performance of major
asset classes has remained positive. In the 12 months ending October 31, 2007,
equity investors were by and large rewarded as, despite several interim
corrections, the Standard & Poor's 500 Index returned 15%, the Dow Jones
Industrial Average returned 18%, and the NASDAQ Composite Index returned 21%.
International developed and emerging markets equities performed even better,
reflecting both a weakening dollar (which boosts returns for U.S. dollar-based
investors) and strong local currency returns, with the MSCI EAFE Developed
Market Index returning 25% and the MSCI Emerging Markets Index returning 68%
over the 12-month period. The U.S. bond market, as measured by the Lehman
Aggregate Bond Index, returned 5% in the 12 months ending October 31, 2007. The
U.S. high-yield bond market, as measured by the Merrill Lynch High Yield Bond
Master II Index, returned 7% for the same period, reflecting its higher coupon
yield.

Sudden swings in the markets are always to be expected. Just as staying
diversified and invested are important investment principles, it is also
important to pay attention to asset allocation. As always, we encourage 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.

Respectfully,

/s/ Daniel K. Kingsbury

PORTFOLIO MANAGEMENT DISCUSSION 10/31/07
- --------------------------------------------------------------------------------

High-yielding bonds produced healthy, positive returns for the 12 months ending
October 31, 2007, despite facing increasing volatility in the closing months of
the period. Strong global growth and healthy corporate profits continued to
provide a favorable backdrop for corporate securities in the opening months of
the period. However, worries about declining home values and a looming crisis
in the subprime mortgage market led to increasing volatility for corporate
bonds as well as equities in the latter months of the fiscal year. In the
following discussion, Andrew D. Feltus, leader of the team managing the Pioneer
Global High Yield Fund, provides an update on the Fund and its investment
strategies for the 12 months ending October 31, 2007.

Q:  How did the Fund perform?

A:  Pioneer Global High Yield Fund's Class A shares had a total return of 8.30%,
    at net asset value, for the 12 months ending October 31, 2007. Over the same
    period, the Merrill Lynch Global High Yield and Emerging Markets Plus Index
    returned 8.47% while the Merrill Lynch High Yield Master II Index rose by
    6.85%. The average return of the 450 funds in Lipper's High Current Yield
    category for the 12 months that ended October 31, 2007 was 6.21%. On October
    31, 2007, the Fund's 30-day SEC yield for Class A shares was 7.84%.

    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 during the 12 months ending October
    31, 2007?

A:  The conditions for investments in high-yield bonds were much more favorable
    during the first half of the fiscal year than the second. Early in the
    period, high-yield bonds, both domestic and foreign, maintained the brisk
    performance momentum built up over the previous two years, benefiting from
    the robust

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

    expansion of the global economy, strong corporate profit growth, and
    remarkably low default rates. The supportive environment began to change
    during the second half of the period, however, as the effects of monetary
    tightening policies by the U.S. Federal Reserve Board and other major
    central banks began to be felt. Early signs of a deceleration of growth,
    particularly in the United States, began to appear, while the most
    speculative part of the domestic economy in recent years - the housing
    industry - began to slump. Falling home values created problems in the
    subprime mortgage market, which began to affect the balance sheets of
    banks and other home lenders as well as investors in some mortgage-related
    securities. As major banks began disclosing information about their
    exposure to subprime mortgages, anxieties spread through the financial
    markets. In a general flight to quality, investors increasingly sought out
    the highest-quality, lowest-risk securities, moving away from high-yield
    corporate bonds as well as equities. The high prices and narrow spreads -
    or yield advantages of high-yield bonds over Treasuries - accelerated the
    flight to quality, as investors saw little reward for taking on the added
    credit risks of lower-rated corporate debt. Despite that trend, the
    underlying economic fundamentals of high-yield issuers remained strong.
    With corporations posting strong profits and solid balance sheets, the
    default rate of domestic high-yield corporate bonds stood at just 1.1% at
    the end of the period - far below the long-term average rates.

    Outside the United States, high-yield bonds in Europe and other major
    industrialized nations performed in line with the domestic market,
    although the appreciation of most foreign currencies against the dollar
    boosted the returns of U.S.-based investors in foreign markets. Emerging
    market debt continued to outperform other parts of the high-yield
    universe, although corporate bonds from emerging markets endured a sharp
    correction when global financial markets became increasingly volatile
    beginning in June 2007.

Q:  What were your principal strategies?

A:  We did not make any notable changes in the overall positioning of the Fund
    during the period, although the Fund did take profits and reduce its
    exposure to the European market, where we thought investors had an overly
    optimistic view of its growth


                                                                               5

    potential. We believed the high-yield market in Europe had become
    expensive, but we continued to favor securities denominated in the
    Norwegian krone, a currency that benefits from the strong demand for oil.
    We believed the U.S. dollar was likely to continue to weaken against other
    currencies, especially emerging markets, and so we maintained the Fund's
    positions in countries such as Brazil, Colombia and Argentina. We had
    reduced the Fund's exposure to emerging markets early in the fiscal year,
    but then added to the Fund's positions late in the period after prices of
    emerging market corporates became more attractive following the June
    market correction.

    While we did not anticipate a recession, we pared back the Fund's exposure
    to the more cyclical - or economically sensitive - areas of the market,
    such as basic industries and materials. As we did so, we added to the
    Fund's investments in less cyclical groups, including energy, health care
    and insurance. We became somewhat more defensive and increased the Fund's
    investments in bank loans to about 6% of Fund assets. Bank loans generally
    have lower credit risk than high-yield bonds.

    At the end of the fiscal year, on October 31, 2007, 58.6% of Fund assets
    were invested in U.S. high-yield corporate bonds, 25.3% in emerging market
    debt and 13.7% in high-yield corporates from other developed nations. A
    total of 9.4% of assets were invested in securities denominated in foreign
    currencies. The average credit rating of Fund holdings was B-. The Fund's
    effective duration - a measure of price sensitivity to changes in interest
    rates - was 4.04 years, while the average maturity of Fund holdings was
    6.66 years.

Q:  What types of investments most affected performance during the 12 months
    ended October 31, 2007?

A:  Many of the Fund's top individual performers during the period were the
    bonds of companies that issued initial public stock offerings and bought
    back much of their outstanding debt at higher prices than their current
    market prices. They included bonds of: New World Resources, a Czech coal
    miner; SulAmerica, a Brazilian insurance company; Codere, a Spanish-based
    operator of slot-machine parlors and other gaming facilities in Europe; and
    Intomex, a Miami-based retailer of computers in Latin America.

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

    Other bond holdings appreciated during the period when their issuing
    companies were acquired by other corporations. Those included bonds of
    Compucom (CRH Holding), a computer services company, and Mirant Jamaica, a
    Jamaican utility. In addition, when Hexion acquired Huntsman, another
    chemical company, our investment in Hexion bonds gained in value as the
    company was required to buy back its previously issued debt under terms of
    loan covenants.

    The Fund's investment in bonds of ATF, a Kazak-based bank, also helped
    performance when the company was acquired by an Italian-based financial
    corporation. However, the Fund's holdings in two other Kazak banks, BTA
    and KKB, did not perform as well. In general, the Fund's increased
    exposure to emerging market corporate bonds late in the period did not
    help, as the securities tended to underperform in a volatile market.
    Individual investments that detracted from the Fund's performance during
    the period included bonds of: Tropicana Casinos & Resorts, which was hurt
    by slowing business at its Atlantic City, N.J. facility; homebuilder
    William Lyons; and Land Source, a joint venture by homebuilder Lennar
    Corp. and the California Public Employees' Retirement System (CALPERS).

Q:  What is your investment outlook?

A:  We think an economic deceleration in the United States is likely, but not a
    recession. The prices of high-yield bonds - as reflected in their spreads or
    yield advantages over Treasuries - are now more attractive after the summer
    corrections, and corporate profits continue to look healthy. We believe the
    default rate for high-yield debt may rise, but principally because it has
    been extremely low relative to long-term averages. We anticipate that the
    Federal Reserve Board will react to developments in the economy and the
    markets and that further cuts in the Fed funds rate are possible.

    Overall, we believe that we have positioned the Fund relatively
    defensively, consistent with the outlook of slowing, but persistent
    economic growth.

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,


                                                                               7

PORTFOLIO MANAGEMENT DISCUSSION 10/31/07                             (continued)
- --------------------------------------------------------------------------------

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 3/1/10 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

returns reflect the deduction of applicable contingent deferred sales charge
(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

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

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

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
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 8/27/01 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 net expense ratio reflects contractual expense limitations currently in
effect through 3/1/2010 for Class Z shares. There can be no assurance that
Pioneer will extend the expense limitation 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.

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

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

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

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

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

Using the Tables

Actual Expenses

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

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

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

Hypothetical Example for Comparison Purposes

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

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

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

1.  Organization and Significant Accounting Policies

Pioneer 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 prospectus(es) contains information regarding
the Fund's principal risks. Please refer to those documents when considering
the Fund's risks.


                                                                              51

NOTES TO FINANCIAL STATEMENTS 10/31/07                               (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 at their fair values as determined by, or under the direction of
    the Board of Trustees and may include yield equivalents or a pricing
    matrix. The Fund may also use the fair value of a security, including a
    non-U.S. security, when the closing market price on the principal exchange
    where the security is traded no longer accurately reflects the value of
    the security. 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


52


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

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

    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 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


                                                                              53

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

    realized capital gains, if any, to its shareowners. Therefore, no federal
    income tax provision is required.

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

    At October 31, 2007, the Fund has reclassified $4,567,519 to increase
    undistributed net investment income and $4,567,519 to decrease accumulated
    net realized gain on investments, credit default swaps and foreign
    currency transactions to reflect permanent book/tax differences. The
    reclassification has no affect on the net asset value of the Fund and is
    designed to present the Fund's capital accounts on a tax basis.

    The tax character of distributions paid during the years ended October 31,
    2007 and 2006 was as follows:



- --------------------------------------------------------------------------------
                                   2007              2006
- --------------------------------------------------------------------------------
                                           
  Distributions paid from:
  Ordinary income              $133,484,600      $64,045,310
  Long-term capital gain          3,117,875        2,102,985
                               ------------      -----------
    Total                      $136,602,475      $66,148,295
                               ============      ===========
- --------------------------------------------------------------------------------


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

  Undistributed ordinary income     $15,803,280
  Undistributed long-term gain       14,654,845
  Dividend payable                   (4,489,347)
  Unrealized depreciation           (19,286,359)
                                    -----------
    Total                           $ 6,682,419

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



54


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

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

    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 UniCredito Italiano S.p.A.
    (UniCredito Italiano), earned $508,067 in underwriting commissions on the
    sale of Class A shares during the year ended October 31, 2007.

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 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 B, Class C, Class Y and Class Z shares
    can bear different transfer agent and distribution expense rates.


                                                                              55

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

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 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, with the Fund's custodian acting as the
    lending agent. When entering into a loan, the Fund receives collateral,
    which is maintained by the custodian and earns income in the form of
    negotiated lenders' fees. The Fund also continues to receive interest or
    payments in lieu of dividends on the securities loaned. Gain or loss on
    the fair value of the loaned securities that may occur during the term of
    the loan will be for the account of the Fund. The loans are secured by
    collateral 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 the Securities Lending Investment Fund, which is sponsored
    by Brown Brothers Harriman & Co., the Fund's custodian.

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


56


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

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

    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.

    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.

3.  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 0.70% 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 year ended October 31, 2007, 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, 2010 for Class A shares and
through March 1, 2008 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 0.85% of the average daily net assets attributable to Class Z
shares. This expense limitation is in effect through March 1, 2010 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 $37,592 in management fees,
administrative costs and certain other services payable to PIM at October 31,
2007.

4.  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 on the Statement of
Assets and Liabilities is $239,635 in transfer agent fees receivable from PIMSS
at October 31, 2007.

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. Currently under the Class A Plan, PFD is
reimbursed for distribution expenses in an amount up to 0.25% of the average
daily net assets attributable to Class A shares. Pursuant to the Class B Plan
and the Class C Plan, the Fund pays PFD 1.00% of the average daily net assets
attributable to each class of shares. The fee consists of a 0.25% service fee
and a 0.75% distribution fee paid as compensation for personal services and/or
account maintenance services or distribution services with regard to Class B
and Class C shares. Included in "Due to affiliates" reflected on the Statement
of Assets and Liabilities is $29,892 in distribution fees payable to PFD at
October 31, 2007.

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


                                                                              59

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 year ended
October 31, 2007, 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 year ended October 31, 2007, the Fund's expenses
were reduced by $57,886 such arrangements.

8.  Forward Foreign Currency Contracts

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

9.  New Pronouncements

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

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.

ADDITIONAL INFORMATION (unaudited)

The qualified interest income percentage, which represents the portion of the
Fund's ordinary income that is exempt from nonresident alien tax withholding is
57.26% for the year ending 10/31/07.

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

To the Board of Trustees and the Shareowners of
Pioneer Global High Yield Fund:

We have audited the accompanying statement of assets and liabilities of Pioneer
Global High Yield Fund (the "Fund") (one of the portfolios constituting the
Pioneer Series Trust VII), including the schedule of investments, as of October
31, 2007, and the related statement of operations for the year then ended, the
statements of changes in net assets for each of the two years in the period
then ended, and the financial highlights for each of the periods indicated
therein. These financial statements and financial highlights are the
responsibility of the Fund's management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we
plan and perform the audit to obtain reasonable assurance about whether the
financial statements and financial highlights are free of material
misstatement. We were not engaged to perform an audit of the Fund's internal
control over financial reporting. Our audits included consideration of internal
control over financial reporting as a basis for designing audit procedures that
are appropriate in the circumstances, but not for the purpose of expressing an
opinion on the effectiveness of the Fund's internal control over financial
reporting. Accordingly, we express no such opinion. An audit also includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements and financial highlights, assessing the accounting
principles used and significant estimates made by management, and evaluating
the overall financial statement presentation. Our procedures included
confirmation of securities owned as of October 31, 2007, by correspondence with
the custodian, brokers and agent banks or by other appropriate auditing
procedures where replies from brokers were not received. We believe that our
audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
Pioneer Global High Yield Fund at October 31, 2007, the results of its
operations for the year then ended, the changes in its net assets for each of
the two years in the period then ended, and the financial highlights for each
of the periods indicated therein, in conformity with U.S. generally accepted
accounting principles.

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

                  SECTION I - POLICY PURPOSE AND APPLICABILITY

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

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

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

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

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

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

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

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

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


    (2) Disclose the percentage of services described in each of paragraphs (b)
   through (d) of this Item that were approved by the audit committee pursuant

after May 6, 2003, the effective date of the new SEC pre-
approval rules, the Fund's audit committee is required to pre-
approve services to affiliates defined by SEC rules to the
extent that the services are determined to have a direct impact
on the operations or financial reporting of the Fund.  For the
years ended October 31, 2007 and 2006, there were no services
provided to an affiliate that required the Fund's audit
committee pre-approval.

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

adviser), and any entity controlling, controlled by, or under common control
with the adviser that provides ongoing services to the registrant for each of
the last two fiscal years of the registrant.

The aggregate non-audit fees for the Fund and affiliates, as
previously defined, totaled approximately $7,820 in 2007 and
$7,515 in 2006.


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