President's Letter

Dear Shareowner,

The U.S. stock market rallied sharply through the third quarter of 2012 amid a
sluggish, but nonetheless growing, U.S. economy. We have been cautiously
optimistic about the U.S. from the start of the year, and the economic data
continue to be encouraging. The housing and auto sectors are benefitting from
record-low interest rates. The climate for consumer and business credit has
improved, and inflation appears to be subdued. While corporate profits slowed in
the third quarter, many U.S. companies continue to have strong balance sheets
and to pay attractive dividends* compared to fixed-income securities.

All of these factors contributed to gains for investors who owned riskier
assets, including equities and higher-yielding corporate bonds. Year to date
through the end of the third quarter, the Standard & Poor's 500 Index returned
16.35%. In fixed income, the Bank of America Merrill Lynch High Yield Master II
Index was up by 12.02% during the same period, while the Barclays Capital
Aggregate Bond Index gained 3.99%. Treasury bonds, by contrast, generated a
comparatively sluggish return of 1.70%, as measured by the Barclays Capital
Intermediate Treasuries Index.

Despite this generally positive picture during the first three quarters of 2012,
investors face powerful macroeconomic challenges in the months ahead. These
include the threat of a so-called "fiscal cliff" in the U.S. budget process
after the November elections, the European sovereign-debt crisis, and slowing
growth in both Europe and China. Investors can continue to count on market
volatility tied to these factors, although we remain optimistic that the
underlying economic trends are moving in the right direction.

At Pioneer, we have long advocated the benefits of staying diversified** and
investing for the long term. And while diversification alone does not assure a
profit or protect against loss in a declining market, we believe in actively
seeking out opportunities in undervalued securities and sectors around the
globe. Our advice, as always, is to work closely with a trusted financial
advisor to discuss your goals and work together to develop an investment
strategy that meets your individual needs. There is no single best strategy that
works for every investor.

*  Dividends are not guaranteed.
** Diversification does not assure a profit or protect against loss in a
   declining market.

Portfolio Management Discussion | 10/31/12

In a low-interest-rate environment, the demand for higher-yielding investment
opportunities remained strong during most of the 12 months ended October 31,
2012. Corporate high-yield bonds and other credit-sensitive securities performed
well during the period, despite some interim market fallbacks caused by
investors' concerns about potential economic weakness in the U.S. and China, and
worries about the possible contagion effects of the ongoing sovereign-debt
problems in Europe. In the following interview, lead portfolio manager Andrew
Feltus and assistant portfolio manager Tracy Wright discuss the factors that
affected the performance of Pioneer Global High Yield Fund during the 12-month
period. Mr. Feltus, senior vice president and portfolio manager at Pioneer, and
Ms. Wright, senior vice president and portfolio manager at Pioneer, are
responsible for the daily management of the Fund.

Q   How did the Fund perform during the 12 months ended October 31, 2012?

A   Pioneer Global High Yield Fund's Class A shares returned 11.89% at net asset
    value during the 12 months ended October 31, 2012, while the Fund's
    benchmarks, the Bank of America Merrill Lynch (BofA ML) High Yield Master II
    Index and the BofA ML Global High Yield and Emerging Markets Plus Index,
    returned 13.18% and 14.67%, respectively. During the same 12-month period,
    the average return of the 503 mutual funds in Lipper's High Current Yield
    Funds category was 12.26%.

Q   Could you describe the investment environment for fixed-income securities
    during the 12 months ended October 31, 2012?

A   Credit-sensitive, high-yielding debt generated solid returns during the
    12-month period. The backdrop for high-yield investing was positive early in
    the period as investors grew more confident that the global economic
    recovery would continue. The market suffered a setback, however, in April
    and May of 2012, as investors' worries about the sovereign-debt problems in
    Greece, Spain, and several other European nations heightened. Fears grew
    about the potential contagion effects that a recession in Europe could have
    on the world economy. The concerns were compounded when some corporations in
    the United States began announcing disappointing profit growth.

    Amid the worries about economic weakness, corporate bonds and other
    credit-sensitive investments produced lackluster results through much of the
    summer of 2012, until the announcements by major central banks--
    particularly the European Central Bank (ECB) and the U.S. Federal Reserve
    Board (the Fed)--of their intentions to inject more liquidity into the
    global financial system to encourage job creation and stimulate economic
    growth.

4 Pioneer Global High Yield Fund | Annual Report | 10/31/12


    The ECB announced in August 2012 that it could become more active in buying
    the short-term debt of peripheral European nations, including Greece and
    Spain, in an effort to keep borrowing rates low for national governments on
    the Continent. Shortly after that, the Fed announced its third round of
    quantitative easing ("QE3") in an effort to encourage lower interest rates
    through the purchasing of mortgage-backed securities in the open market.
    Additionally, monetary authorities in China announced that they, too, were
    lowering short-term interest rates and easing credit conditions.

    The combination of the central banks' announcements helped trigger a sharp
    rally in the financial markets, and high-yield and other credit-sensitive
    securities outperformed through the end of the period in October.

    While economic benchmarks did not signal robust growth, evidence of
    improving economic conditions and progress in new-job creation proved
    sufficient to dampen investors' fears that the world economy might fall into
    a double-dip recession. U.S. high-yield bonds performed very well during the
    market rally, but the strongest returns came from the emerging markets.
    Emerging market debt rebounded sharply after producing lackluster returns
    earlier in the period--struggles that were the result of concerns about the
    strength of the global economy and worries that the sovereign-debt problems
    of Argentina might be indicative of wider problems in other emerging
    markets.

Q   How did you position the Fund during the 12 months ended October 31, 2012,
    and how did the positioning affect the Fund's underperformance relative to
    its two BofA ML benchmarks during the period?

A   The Fund performed well during the period, especially during the 10 months
    of the period occurring in calendar year 2012, but benchmark-relative
    results for the full fiscal year dating back to November 1, 2011, were
    adversely affected by one disappointing investment, as the Fund's holdings
    in airport facility securities backed by American Airlines went down in
    value after AMR, the parent company of the airline, unexpectedly filed for
    bankruptcy protection in November 2011.

    Overall, domestic high-yield corporate bonds, which represented the largest
    component of the portfolio, contributed positively to the Fund's relative
    performance, which also was supported by portfolio exposure to emerging
    market debt, a strong performer during the period (outside of Argentina).

    Also holding back benchmark-relative results somewhat was the Fund's
    exposure to bank loans. While the portfolio's bank-loan investments
    performed well, they produced lower yields, in general, than high-yield
    bonds. About 8% of the Fund's net assets were invested in floating-rate bank
    loans as of October 31, 2012.

                     Pioneer Global High Yield Fund | Annual Report | 10/31/12 5


    The Fund's underweight to the euro had a negative effect on relative
    performance as well during 2012, when the euro rallied against the U.S.
    dollar, but the Fund's holdings in underlying European high-yield corporate
    bonds, nevertheless, performed very well.

    As of October 31, 2012, U.S. high-yield corporates represented the largest
    allocation in the Fund's portfolio, at 30.1% of net assets, with U.S.
    investment-grade corporates representing another 2.8%. Floating-rate bank
    loans accounted for 8.0% of the Fund's net assets, while emerging market
    corporates represented another 23.5% of net assets, supplemented by a 5.2%
    weighting in emerging market sovereign debt. High-yield corporate bonds
    issued by companies in developed foreign nations accounted for an additional
    13.6% of net assets. The Fund also had exposures to convertible bonds (6.5%
    of net assets) and event-linked (catastrophe) bonds (3.5% of net assets).

Q   What individual securities, aside from AMR Corporation, had the biggest
    effect on the Fund's performance during the 12 months ended October 31,
    2012?

A   The Fund's emerging market corporate bond holdings performed particularly
    well during the period, with strong results coming from a diverse number of
    positions, including MIE Holdings, a Chinese energy company; Bio Pappel, a
    Mexican packaging company; and Vedanta Resources, an Indian metals and
    mining corporation. Another solid contributor in the Fund's portfolio was
    the debt of Cemex, the Mexico-based global building materials corporation.
    The securities gained in value after Cemex solidified its finances by
    selling off part of its Latin American operations.

    Among the Fund's U.S. holdings, securities issued by BWAY, a packaging firm,
    appreciated in value after private-equity investors made a buyout proposal.
    Elsewhere, the Fund's investment in the bonds of Basell Finance, a
    subsidiary of the Dutch chemical company LyondellBasell, performed well as
    Lyondell's debt was upgraded to investment grade during the 12-month period.

    In addition to the disappointing performance from the AMR-related debt, the
    Fund's investments in Argentina also detracted from results during the
    period as Argentinian debt fell out of favor due to lack of investor
    confidence in the government's policies, with the nationalization of energy
    firm YPF's assets a particular concern. YPF is a subsidiary of Spanish
    energy firm Repsol. As a result, the Fund's positions in the corporate debt
    of Argentinian companies Banco Macro and Edenor declined in value.

6 Pioneer Global High Yield Fund | Annual Report | 10/31/12


Q   Did the use of derivatives affect the Fund's performance during the 12
    months ended October 31, 2012?

A   The Fund did invest in some currency forward contracts, which were used to
    reduce the risks of changes in the relative values of currencies. The
    contracts had a slightly positive effect on the Fund's performance.

Q   What is your investment outlook?

A   The short-term outlook is clouded by uncertainties about whether the United
    States' elected leaders in Washington can reach an agreement on solving the
    approaching "fiscal cliff" scenario. At the conclusion of the national
    elections, the President and the Congress faced three significant financial
    challenges: potentially increasing the nation's debt ceiling; sequestration,
    which calls for unspecified, but deep and automatic across-the-board
    spending cuts in the absence of some budget agreement; and the expiration of
    the Bush-era tax cuts. The automatic spending cuts and the expiration of the
    Bush-era tax cuts both are scheduled to occur at the end of 2012.

    If there is a successful resolution to the debate over the looming policy
    issues, we believe we should see less volatility in the markets and a return
    to a focus on fundamental investment principles. While the U.S. economy's
    growth, as measured by gross domestic product (GDP), clearly slowed in the
    first and second quarters of 2012, we believe the prospects for improving
    conditions are good. In fact, GDP growth for the third quarter recently was
    revised upward to roughly 2.7%. The more accommodative policy stances taken
    by the major central banks in the U.S., Europe, China and Japan also should
    help to encourage economic expansion and an improvement in corporate
    profits.

    In an environment of extremely low interest rates, we think there should be
    continuing investor appetite for corporate bonds and other credit-sensitive
    securities that offer yield premiums greater than those available in the
    high-grade debt market. Nevertheless, the low absolute level of interest
    rates does limit the total-return potential of fixed-income investments in
    general.

    In addition to our emphasis on corporate bonds in the Fund, we continue to
    favor having healthy portfolio exposures to bank loans and catastrophe
    bonds, both of which have floating interest rates. Although the two groups
    did not perform as well as high-yield bonds during the past fiscal year
    ended October 31, 2012, we believe their prospects should improve over the
    next two to three years, especially if interest rates start to rise and
    floating-rate securities start paying out higher yields. Catastrophe bonds
    also may fare well in the shorter term, as they were not seriously affected
    by the recent hurricane season. Even October's devastating Hurricane Sandy
    did not have a major impact on catastrophe bonds, as private insurers did
    not bear most of the effects of the damage inflicted on the U.S. East Coast.

                     Pioneer Global High Yield Fund | Annual Report | 10/31/12 7


    The Funds remains underweight to Europe, but we intend to continue to look
    for individual investment opportunities there. We believe the most
    interesting growth opportunities may lie in the emerging markets, where many
    nations have strong balance sheets, disciplined fiscal and monetary
    policies, and attractive real interest rates. There are, however, areas of
    concern in the emerging markets, such as Argentina, where investors need to
    be attentive to corporate-governance problems.

    Looking ahead, we will seek to identify potential investment opportunities
    for the Fund created by growth in the emerging markets and potential
    weakness in the U.S. dollar and the euro.

Please refer to the Schedule of Investments on pages 18-53 for a full listing of
Fund securities.

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 issuers of underlying securities and their inability to meet their
debt obligations.

Prepayment risk is the chance that mortgage-backed securities 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.

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.

Past performance is no guarantee of future results, and there is no guarantee
that market forecasts discussed will be realized.

or the factors influencing the Fund's historical or future performance are

Index Definition
--------------------------------------------------------------------------------
The Bank of America (BofA) 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). The BofA ML High Yield Master II Index
is a commonly accepted measure of the performance of high-yield securities.
Index returns are calculated monthly, assume reinvestment of dividends and,
unlike Fund returns, do not reflect any fees, expenses or sales charges. It is
not possible to invest directly in an index.

The indices defined here pertain to the "Value of $10,000 Investment" and "Value
of $5 Million Investment" charts appearing on pages 11-15.

Call 1-800-225-6292 or visit us.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 4.50% sales charge. All results are historical and assume the
reinvestment of dividends and capital gains. Other share classes are available
for which performance and expenses will differ.

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

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

Call 1-800-225-6292 or visit us.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.

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
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.

Performance shown for Class Y shares for periods prior to the inception of 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 for Class Y
shares prior to their inception on December 28, 2005, would have been higher
than the performance shown. Class Y shares are not subject to sales charges and

Performance shown for Class Z shares for periods prior to the inception of Class
Z shares on July 6, 2007, 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

Comparing Ongoing Fund Expenses

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

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

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

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

Using the Tables
--------------------------------------------------------------------------------
Actual Expenses

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

(1) Divide your account value by $1,000
    Example: an $8,600 account value (divided by) $1,000 = 8.6

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

    shares, respectively, multiplied by the average account value over the
    period, multiplied by 184/366 (to reflect the one-half 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.

Notes to Financial Statements | 10/31/12 (Consolidated)

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. The Fund is registered under the Investment
Company Act of 1940 as a 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 designated as 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.
Effective as of the close of business on December 31, 2009, Class B shares are
no longer offered to new or existing shareholders, except that dividends and/or
capital gain distributions may continue to be reinvested in Class B shares, and
shareholders may exchange their Class B shares for Class B shares of other
Pioneer funds, as permitted by existing exchange privileges. Each class of
shares represents an interest in the same portfolio of investments of the Fund
and has identical rights (based on relative net asset values) to assets and
liquidation proceeds. Share classes can bear different rates of class-specific
fees and expenses such as transfer agent and distribution fees. Differences in
class-specific fees and expenses will result in differences in net investment
income and, therefore, the payment of different dividends from net investment
income earned by each class. The Amended and Restated Declaration of Trust of
the Fund gives the Board the flexibility to specify either per share voting or
dollar-weighted voting when submitting matters for shareholder approval. Under
per share voting, each share of a class of the Fund is entitled to one vote.
Under dollar-weighted voting, a shareholder's voting power is determined not by
the number of shares owned, but by the dollar value of the shares on the record
date. Each share class has exclusive voting rights with respect to matters
affecting only that class, including with respect to the distribution plan for
that class. There is no distribution plan for Class Y shares or Class Z shares.
Class B shares convert to Class A shares approximately 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.

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:

Pioneer Global High Yield Fund | Annual Report | 10/31/12 63


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. Senior
    floating rate loan interests (senior loans) are valued in accordance with
    guidelines established by the Board of Trustees at the mean between the last
    available bid and asked prices from one or more brokers or dealers as
    obtained from Loan Pricing Corporation, an independent pricing service.
    Senior loans for which no reliable price quotes are available will be valued
    by Loan Pricing Corporation through the use of pricing matrices to determine
    valuations. Fixed income securities with remaining maturity of more than
    sixty days are valued at prices supplied by independent pricing services,
    which consider such factors as market prices, market events, quotations from
    one or more brokers, Treasury spreads, yields, maturities and ratings.
    Valuations may be supplemented by dealers and other sources, as required.
    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. Equity
    securities that have traded on an exchange are valued at the last sale price
    on the principal exchange where they are traded. Equity securities that have
    not traded on the date of valuation, or securities for which sale prices are
    not available, generally are valued using the mean between the last bid and
    asked prices. Short-term fixed income securities with remaining maturities
    of sixty days or less generally are valued at amortized cost. Money market
    mutual funds are valued at net asset value.

    Trading in foreign securities is substantially completed each day at various
    times prior to the close of the NYSE. The values of such securities used in
    computing the net asset value of the Fund's shares are determined as of such
    times.

    Securities or senior loans for which independent pricing services are unable
    to supply prices or for which market prices and/or quotations are not
    readily available or are considered to be unreliable are valued using fair
    value methods pursuant to procedures adopted by the Board of Trustees. The
    Fund may use fair value methods if it is determined that a significant event
    has occurred after the close of the exchange or market on which the security
    trades and prior to the determination of the Fund's net asset value.
    Examples of a significant event might include political or economic news,
    corporate restructurings, natural disasters, terrorist activity or trading
    halts. Thus, the valuation of the Fund's securities may differ from exchange
    prices.

    At October 31, 2012, two securities were valued using fair value methods (in
    addition to securities valued using prices supplied by independent pricing
    services) representing 0.2% of net assets. Inputs used when applying fair
    value methods to value a security may include credit ratings, the financial
    condition of the company, current market conditions and comparable
    securities.

64 Pioneer Global High Yield Fund | Annual Report | 10/31/12


    Principal amounts of mortgage-backed securities are adjusted for monthly
    paydowns. Premiums and discounts related to certain mortgage-backed
    securities are amortized or accreted in proportion to the monthly paydowns.
    All discounts/premiums on debt securities are accreted/amortized for
    financial reporting purposes over the life of the respective securities, and
    such accretion/amortization is included in interest income.

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

    Gains and losses on sales of investments are calculated on the identified
    cost method for both financial reporting and federal income tax purposes.

B.  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 may enter into forward foreign currency contracts (contracts) for
    the purchase or sale of a specific foreign currency at a fixed price on a
    future date. 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).

                    Pioneer Global High Yield Fund | Annual Report | 10/31/12 65


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. As of
    October 31, 2012, the Fund did not have any interest and penalties related
    to unrecognized tax positions, which, if applicable, would be recorded as an
    income tax expense in the Statement of Operations. Tax years for the prior
    three fiscal years remain subject to examination by federal and state tax
    authorities.

    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, 2012, the Fund reclassified $2,083,984 to increase
    distributions in excess of net investment income, $2,689,147 to decrease
    accumulated net realized loss on investments and foreign currency
    transactions and $605,163 to decrease paid-in capital to reflect permanent
    book/tax differences. The reclassification has no impact on the net asset
    value of the Fund and is designed to present the Fund's capital accounts
    on a tax basis.

    At October 31, 2012, the Fund was permitted to carry forward indefinitely
    $6,237,181 of short term losses under the Regulated Investment Company
    Modernization Act of 2010 without limitation. Additionally, at October 31,
    2012, the Fund had a net capital loss carryforward of $235,848,362, of which
    the following amounts will expire between 2016 and 2018 if not utilized:
    $4,718,467 in 2016, $204,858,985 in 2017 and $26,270,910 in 2018

    The tax character of distributions paid during the years ended October 31,
    2012 and October 31, 2011 were as follows:



--------------------------------------------------------------------------------
                                                         2012               2011
--------------------------------------------------------------------------------
                                                             
    Distributions paid from:
    Ordinary income                             $ 197,278,625      $ 204,322,757
--------------------------------------------------------------------------------
       Total                                    $ 197,278,625      $ 204,322,757
================================================================================


66 Pioneer Global High Yield Fund | Annual Report | 10/31/12


    The following shows the components of distributable earnings on a federal
    income tax basis at October 31, 2012:



--------------------------------------------------------------------------------
                                                                            2012
--------------------------------------------------------------------------------
                                                               
    Distributable earnings:
    Capital loss carryforward                                     $(242,085,543)
    Current year dividend payable                                    (2,109,680)
    Unrealized depreciation                                         (94,313,502)
--------------------------------------------------------------------------------
       Total                                                      $(338,508,725)
================================================================================


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

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 $206,236 in underwriting commissions on the sale of Class A shares
    during the year ended October 31, 2012.

F.  Class Allocations

    Income, common expenses and realized and unrealized gains and losses are
    calculated at the Fund level and allocated daily to each class of shares
    based on its respective percentage of adjusted net assets at the beginning
    of the day. During the year ended October 31, 2012, the Fund recognized
    gains of $28,496 in the settlement of class action lawsuits from several
    different companies, as reflected on the Statement of Operations.

    Distribution fees are calculated based on the average daily net asset value
    attributable to Class A, Class B and Class C shares of the Fund,
    respectively (see Note 5). Class Y and Class Z shares do not pay
    distribution fees. All expenses and fees paid to the transfer agent, Pioneer
    Investment Management Shareholder Services, Inc. (PIMSS), for its services
    are allocated among the classes of shares based on the number of accounts in
    each class and the ratable allocation of related out-of-pocket expenses (see
    Note 3).

                    Pioneer Global High Yield Fund | Annual Report | 10/31/12 67


    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 and at the same time, except that net
    investment income dividends to Class A, Class B, Class C, Class Y and Class
    Z shares can reflect different transfer agent and distribution expense
    rates.

G.  Risks

    At times, the Fund's investments may represent industries or industry
    sectors that are interrelated or have common risks, making the Fund 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 contains unaudited information regarding the Fund's principal
    risks. Please refer to that document when considering the Fund's principal
    risks.

    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.

H.  Repurchase Agreements

    With respect to repurchase agreements entered into by the Fund, the value of
    the underlying securities (collateral), including accrued interest, is
    required to be equal to or in excess of the repurchase price. The collateral
    for all repurchase agreements is held in safekeeping in the customer-only
    account of the Fund's custodian or a subcustodian of the Fund. 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.

68 Pioneer Global High Yield Fund | Annual Report | 10/31/12


I.  Securities Lending

    The Fund may lend securities in its portfolio to certain broker-dealers or
    other institutional investors. When entering into a securities loan
    transaction, the Fund typically receives cash collateral from the borrower
    equal to at least the value of the securities loaned, which is invested in
    temporary investments. Credit Suisse AG, New York Branch, as the Fund's
    securities lending agent, manages the Fund's securities lending collateral.
    The income earned on the investment of collateral is shared with the
    borrower and the lending agent in payment of any rebate due to the borrower
    with respect to the securities loan, and in compensation for the lending
    agent's services to the Fund. The Fund also continues to receive payments in
    lieu of dividends or interest on the securities loaned. Gain or loss on the
    value of the loaned securities that may occur during the term of the loan
    will be for the account of the Fund. The amount of the collateral is
    required to be adjusted daily to reflect any price fluctuation in the value
    of the loaned securities. If the required market value of the collateral is
    less than the value of the loaned securities, the borrower is required to
    deliver additional collateral for the account of the Fund prior to the close
    of business on that day. The Fund has the right, under the lending
    agreement, to terminate the loan and recover the securities from the
    borrower with prior notice. The Fund is required to return the cash
    collateral to the borrower and could suffer a loss if the value of the
    collateral, as invested, has declined. As of October 31, 2012, the Fund had
    no securities on loan.

J.  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 portfolio 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.

                    Pioneer Global High Yield Fund | Annual Report | 10/31/12 69


    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.

    During the year ended October 31, 2012, the Fund opened one credit default
    swap, with a notional principal of $4,100,000, which was still open at year
    end. Credit default swap contracts outstanding at year end are listed at the
    end of the Fund's schedule of investments.

2. Management Agreement

PIM, a wholly owned indirect subsidiary of UniCredit, 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; 0.60% of the next $500 million; 0.55%
of the next $500 million; and 0.45% on assets over $2 billion. For the year
ended October 31, 2012, the effective management fee (excluding waivers and/or
assumption of expenses) was equivalent to 0.60% of the Fund's average daily net
assets.

PIM has contractually agreed to limit ordinary operating expenses to the extent
required to reduce Fund expenses to 1.10%, 2.00%, 2.00% and 0.90% of the average
daily net assets attributable to Class A, Class B, Class C and Class Z shares,
respectively. Class Y shares do not have an expense limitation. These expense
limitations were in effect through March 1, 2012.

70 Pioneer Global High Yield Fund | Annual Report | 10/31/12


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 as administrative reimbursements. Included in
"Due to affiliates" reflected on the Statement of Assets and Liabilities is
$139,874 in management fees, administrative costs and certain other
reimbursements payable to PIM at October 31, 2012.

Effective March 5, 2012, PIM has retained Brown Brothers Harriman & Co. to
provide certain sub-administration and accounting services to the Fund.

3. Transfer Agent

PIMSS, a wholly owned indirect subsidiary of UniCredit, provides substantially
all transfer agent and shareowner services to the Fund at negotiated rates.

In addition, the Fund reimburses PIMSS for out-of-pocket expenses incurred by
PIMSS related to shareholder communications activities such as proxy and
statement mailings, outgoing phone calls and omnibus relationship contracts. For
the year ended October 31, 2012, such out-of-pocket expenses by class of shares
were as follows:



--------------------------------------------------------------------------------
Shareholder Communications:

Class A                                                               $  513,329
Class B                                                                   40,107
Class C                                                                  249,677
Class Y                                                                1,540,430
Class Z                                                                   11,868

   Total                                                              $2,355,411
================================================================================


Included in "Due to affiliates" reflected on the Statement of Assets and
Liabilities is $576,858 in transfer agent fees and out-of-pocket reimbursements
payable to PIMSS at October 31, 2012.

4. Basis for Consolidation of the Financial Statements

The consolidated financial statements of the Fund include the accounts of the
Subsidiary. All intercompany accounts and transactions have been eliminated in
consolidation. The Subsidiary, a Delaware corporation, was incorporated on
February 10, 2011 and is wholly-owned and controlled by the Fund. It is intended
that the Fund will remain the sole shareholder of, and will continue to control,
the Subsidiary. The Subsidiary acts as an investment vehicle for the Fund's
interest in Blaze Recycling and Metals LLC, Class A Units. As of October 31,
2012, the Subsidiary represented approximately $2,977,188 or approximately 0.1%
of the net assets of the Fund.

                    Pioneer Global High Yield Fund | Annual Report | 10/31/12 71


5. Distribution Plan

The Fund has adopted a Distribution Plan pursuant to Rule 12b-1 of the
Investment Company Act of 1940 with respect to its Class A, Class B and Class C
shares. 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 also 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. Included in "Due to affiliates" reflected on the Statement of Assets and
Liabilities is $35,871 in distribution fees payable to PFD at October 31, 2012.

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 12 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.
Shares purchased as part of an exchange remain subject to any CDSC that applied
to the original purchase of those shares. There is no CDSC for Class Y or Class
Z shares. Proceeds from the CDSCs are paid to PFD. For the year ended October
31, 2012, CDSCs in the amount of $65,289 were paid to PFD.

6. Line of Credit Facility

The Fund, along with certain other funds in the Pioneer Family of Funds (the
Funds), participates in a 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 the amount available under the facility or
the limits set for borrowing by the Fund's prospectus and the 1940 Act. The
credit facility in effect until January 20, 2012 was in the amount of $165
million. Under such facility, interest on borrowings was payable at the higher
of the London Interbank Offered Rate (LIBOR) on the borrowing date plus 1.25% on
an annualized basis or the Federal Funds Rate on the borrowing date plus 1.25%
on an annualized basis. The credit facility in effect as of February 15, 2012 is
in the amount of $215 million. Under such facility, depending on the type of
loan, interest on borrowings is payable at LIBOR plus 0.90% on an annualized
basis, or the Alternate Base Rate, which is the greater of (a) the facility's
administrative agent's daily announced prime rate on the borrowing date, (b) 2%
plus the Federal Funds Rate on the borrowing date and (c) 2% plus the overnight
Euro dollar rate on the

72 Pioneer Global High Yield Fund | Annual Report | 10/31/12


borrowing date. The Funds pay an annual commitment fee to participate in a
credit facility. The commitment fee is allocated among participating Funds based
on an allocation schedule set forth in the credit agreement.

For the year ended October 31, 2012, the average daily amount of borrowings
outstanding during the period was $17,900,000. The related weighted average
annualized interest rate for the period was 1.25%, and the total interest
expense on such borrowings was $8,256, which is included in interest expense,
located on the Statement of Operations. As of October 31, 2012, there were no
borrowings outstanding.

7. Expense Offset Arrangements

The Fund has entered into certain expense offset arrangements with PIMSS which
may result in a reduction in the Fund's total expenses due to interest earned on
cash held by PIMSS. For the year ended October 31, 2012, the Fund's expenses
were not reduced under such arrangements.

8. Forward Foreign Currency Contracts

At October 31, 2012, the Fund had entered into various forward foreign currency
contracts that obligate the Fund to deliver or take delivery of currencies at
specified future maturity dates. Alternatively, prior to the settlement date of
a forward foreign currency contract, the Fund may close out such contract by
entering into an offsetting contract. The average value of portfolio hedge
contracts open during the year ended October 31, 2012 was $35,514,043.

Open portfolio hedges at October 31, 2012 were as follows:

Report of Independent Registered Public Accounting Firm

To the Board of Trustees of the Series VII Trust and the Shareowners of
Pioneer Global High Yield Fund:
--------------------------------------------------------------------------------
We have audited the accompanying consolidated statement of assets and
liabilities, including the consolidated schedule of investments, of Pioneer
Global High Yield Fund (the "Fund") (one of the portfolios constituting the
Series VII Trust) as of October 31, 2012, and the related consolidated statement
of operations for the year then ended, the consolidated 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 Trust'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 Trust'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 Trust'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, 2012, by correspondence with the custodian,
brokers and agent banks. We believe that our audits provide a reasonable basis
for our opinion.

In our opinion, the consolidated 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, 2012, the consolidated
results of its operations for the year then ended, the changes in its net assets
for 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.

President's Letter

Dear Shareowner,

The U.S. stock market rallied sharply through the third quarter of 2012 amid a
sluggish, but nonetheless growing, U.S. economy. We have been cautiously
optimistic about the U.S. from the start of the year, and the economic data
continue to be encouraging. The housing and auto sectors are benefitting from
record-low interest rates. The climate for consumer and business credit has
improved, and inflation appears to be subdued. While corporate profits slowed in
the third quarter, many U.S. companies continue to have strong balance sheets
and to pay attractive dividends* compared to fixed-income securities.

All of these factors contributed to gains for investors who owned riskier
assets, including equities and higher-yielding corporate bonds. Year to date
through the end of the third quarter, the Standard & Poor's 500 Index returned
16.35%. In fixed income, the Bank of America Merrill Lynch High Yield Master II
Index was up by 12.02% during the same period, while the Barclays Capital
Aggregate Bond Index gained 3.99%. Treasury bonds, by contrast, generated a
comparatively sluggish return of 1.70%, as measured by the Barclays Capital
Intermediate Treasuries Index.

Despite this generally positive picture during the first three quarters of 2012,
investors face powerful macroeconomic challenges in the months ahead. These
include the threat of a so-called "fiscal cliff " in the U.S. budget process
after the November elections, the European sovereign-debt crisis, and slowing
growth in both Europe and China. Investors can continue to count on market
volatility tied to these factors, although we remain optimistic that the
underlying economic trends are moving in the right direction.

At Pioneer, we have long advocated the benefits of staying diversified** and
investing for the long term. And while diversification alone does not assure a
profit or protect against loss in a declining market, we believe in actively
seeking out opportunities in undervalued securities and sectors around the
globe. Our advice, as always, is to work closely with a trusted financial
advisor to discuss your goals and work together to develop an investment
strategy that meets your individual needs. There is no single best strategy that
works for every investor.

    declining market.

Portfolio Management Discussion | 10/31/12

Despite re-occurring concerns about the strength and durability of the global
economic recovery, credit-sensitive fixed-income investments produced positive
returns during the 12 months ended October 31, 2012, outperforming low-yielding
government bonds. In the following interview, Charles Melchreit discusses the
performance of Pioneer Global Aggregate Bond Fund during the 12-month period.
Mr. Melchreit, vice president and portfolio manager at Pioneer, is responsible
for the daily management of the Fund, along with Mr. Tanguy Le Saout, Head of
European Fixed-Income Portfolio Management and European Fixed-Income Research at
Pioneer.

Q   How did the Fund perform during the 12 months ended October 31, 2012?

A   Pioneer Global Aggregate Bond Fund's Class A shares returned 5.98% at net
    asset value during the 12 months ended October 31, 2012, while the Fund's
    benchmark, the Barclays Capital Global Aggregate Bond Index (the Barclays
    Index) returned 3.54%. During the same period, the average return of the 191
    mutual funds in Lipper's Global Income Funds category was 6.64%.

Q   How would you describe the investment environment for fixed-income
    securities during the 12 months ended October 31, 2012?

A   Credit-sensitive sectors in the world's fixed-income markets tended to
    produce the best performance during the 12-month period, despite bursts of
    market volatility that resulted in temporary retreats from the dominant
    market trends. To be sure, markets in the United States, in developed
    European nations, and in the emerging markets--the three major market groups
    that make up the Fund's investable universe--behaved differently from each
    other during the period, as investors in each area reacted to certain
    developments. By the end of the 12-month period, however, the overall trend
    was that lower-rated, more credit-sensitive securities produced the best
    relative results, with emerging market debt and high-yielding and
    investment-grade corporate bonds substantially outperforming the
    higher-quality, sovereign-government debt of major industrialized nations.

    In the United States, the domestic economy continued to grow, albeit slowly,
    and the credit sectors outperformed. Corporate bonds and other credit-linked
    securities performed very well early in the period, but then faded in the
    late spring and early summer of 2012 as investors worried about the
    sustainability of the economic rebound, especially in the face of
    intensifying sovereign-debt problems in Europe and evidence of economic

4 Pioneer Global Aggregate Bond Fund | Annual Report | 10/31/12


    weakening in China and other Asian nations. The resulting fears that the
    U.S. economy might fall back into recession were somewhat alleviated,
    however, when the Federal Reserve Board (the Fed) in late summer announced
    its third round of quantitative easing ("QE3") to encourage lower interest
    rates by buying mortgage-backed securities on the open market. After the
    Fed's announcement, the credit sectors again rallied and the comeback
    continued through the end of the period on October 31, 2012, although market
    anxieties did increase in the run-up to the November elections as investors
    grew concerned about whether the nation's political leaders would be able to
    resolve deep disagreements about tax and spending policies (the approaching
    "fiscal cliff ") at the end of 2012.

    In Europe, the trend favoring credit-sensitive investments was not as
    strong, as the markets worried about the deepening sovereign-debt problems
    in Spain and other smaller markets. The European Central Bank (ECB) did,
    however, announce a series of steps to aid debtor nations and ease
    borrowing. While the ECB's actions helped to avoid the worst-case scenario
    of potential defaults, they were not sufficient to keep most European
    economies from slipping back into recession. As a result, the fixed-income
    markets in Europe produced lackluster results, at best, during most of the
    12 months ended October 31, 2012, although they did recover somewhat towards
    the end of the period as the ECB became more aggressive in easing monetary
    policy.

    The economic problems in Europe had a spillover effect on China, which ships
    a major portion of its exports to European markets. Early in the period, in
    particular, the effects of weakening growth in China also became a drag on
    other Asian countries as well as emerging market economies in
    general--countries that were dependent on demand from China. Investors also
    worried about the change in Chinese political leadership scheduled to take
    place in early 2013. Emerging market securities, however, staged a comeback
    late in the Fund's fiscal year due to renewed confidence that China would
    not fall into recession and that the global economy would continue to
    recover, despite the ongoing problems in Europe.

    The developments in the United States, Europe and China affected different
    markets in varying ways during the 12-month period. Non-U.S. dollar
    currencies make up more than 50% of the value in the benchmark Barclays
    Index, and, thus, currency positioning was important during the period.

    During the 12 months ended October 31, 2012, the U.S. dollar (USD) performed
    well in international currency markets. Non-USD currencies that also fared
    well included the Canadian, Australian and New Zealand dollars as well as
    the British pound and the currencies of some emerging market nations, such
    as Korea, Mexico, Malaysia, the Philippines and

                 Pioneer Global Aggregate Bond Fund | Annual Report | 10/31/12 5


    Turkey. In contrast, the euro weakened and performed poorly during the
    period, as did the correlated currencies of Switzerland, Denmark, Norway and
    Sweden. In addition, the Japanese yen and the currencies of the emerging
    market nations of Indonesia and South Africa also weakened.

Q   What were the Fund's main investment strategies during the 12 months ended
    October 31, 2012, and how did the strategies affect the Fund's performance
    relative to the Barclays Index?

A   The Fund's sector allocations gave substantial support to benchmark-
    relative performance during the 12-month period, particularly our decision
    to overweight the portfolio to the debt of U.S. financial institutions, and
    to underweight U.S. Treasuries. Among the Fund's U.S. financial holdings,
    investments in collateralized mortgage obligations (CMOs) were particularly
    successful during the period, as yield-seeking investors sought out a sector
    that had been largely avoided since the market setbacks of 2008 and 2009.
    Most of the Fund's CMO holdings were in non-agency securities.

    Despite the portfolio's success in U.S. financials, our decision to
    underweight European and British financials hurt benchmark-relative results
    during the period. The ECB's actions in support of the governments of
    Greece, Spain, and other nations struggling with sovereign-debt issues
    helped to lift the values of the debt of banks and other institutions that
    were holding the troubled sovereign debt. As a result, the Fund's
    underweight position in those securities detracted from relative results.

    The portfolio's currency strategy was successful during the period and also
    contributed to results, as an overweight position in the USD was a major
    factor in the Fund's benchmark-relative outperformance. At the end of the
    Fund's fiscal year on October 31, 2012, approximately 57% of the Fund's
    investments were denominated in the USD, representing a large overweight
    relative to the 41% allocation in the Barclays Index. Also aiding the Fund's
    performance during the period were overweight exposures to the Australian
    and New Zealand dollars and the Philippine peso. At the same time, the
    Fund's underweights to the euro and the Japanese yen supported results,
    given the struggles of both currencies during the period. Despite the
    overall success of the Fund's currency strategy, the portfolio's exposures
    to the currencies of Indonesia, Sweden and Canada detracted from
    benchmark-relative results during the period.

    While the Fund's sector and currency positioning aided results during the
    period, the portfolio's somewhat shorter-duration positioning was a slight
    detractor from relative returns during the period, as longer-term sovereigns
    rallied when market interest rates declined. The negative effects of the

6 Pioneer Global Aggregate Bond Fund | Annual Report | 10/31/12


    Fund's overall duration strategy were offset somewhat by the positive
    effects of a longer-duration stance in U.S. and Mexican sovereigns.
    (Duration is a measure of a portfolio's price sensitivity to changes in
    interest rates.)

    As of October 31, 2012, U.S. corporate debt and foreign investment-grade
    debt represented the Fund's largest sector allocations.

Q   What individual holdings contributed to or detracted from the Fund's
    performance during the 12 months ended October 31, 2012?

A   Among individual holdings, U.S. commercial mortgages issued by Deutsche Bank
    and the corporate bonds of building materials company Masco performed
    particularly well for the Fund during the 12-month period.

    Disappointing portfolio holdings during the period included the convertible
    debt of U.S. truck manufacturer Navistar and bonds issued by Credit Foncier,
    a French institution that also guaranteed the mortgages securing the bonds.

Q   What is your investment outlook?

A   The riskier segments of the global fixed-income markets have been
    outperforming high-quality government debt, and we continue to favor
    investing the Fund in credit-linked debt rather than Treasuries and other
    government securities. Corporate bonds and mortgage-backed securities appear
    more attractive to us on a relative basis, especially in light of the risks
    associated with low-yielding sovereign securities at a time when many
    governments find themselves in weak fiscal positions.

    We have opportunistically increased the Fund's exposure to investments of
    stronger emerging market nations, including the Philippines, Indonesia,
    Malaysia and India, although the positions still remain just a small part of
    the overall portfolio.

    We believe that we may also see a developing opportunity in non-financial
    European bonds, which may be undervalued in light of the overall strengths
    of their issuing corporations--many of which are global companies that
    derive a major portion of their revenues from operations outside Europe.

    In recent years, the Fund has benefited from investments in commodity-
    driven economies, such as Australia and Canada. We continue to see some
    opportunities in that area, although we expect to be very selective.

Please refer to the Schedule of Investments on pages 16-43 for a full listing of
Fund securities.

The portfolio may invest in mortgage-backed securities, which during times of
fluctuating interest rates may increase or decrease more than other fixed-income
securities. Mortgage-backed securities are also subject to pre-payments.

The portfolio may invest in derivative securities, which may include futures and
options. These types of instruments can increase price fluctuation.

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.

Investments in the Fund are subject to possible loss due to the financial
failure of issuers of underlying securities and their inability to meet their
debt obligations. Investments in high-yield or lower-rated securities are
subject to greater-than- average risk.

Investing in foreign and/or emerging market securities involves risks relating
to interest rates, currency exchange rates, economic, and political conditions.

At times, the Fund's investments may represent industries or industry sectors
that are interrelated or have common risks, making it more susceptible to any
economic, political, or regulatory developments or other risks affecting those
industries and sectors.

These risks may increase share price volatility.

Past performance is no guarantee of future results, and there is no guarantee
that market forecasts discussed will be realized.

month-end performance results. Current performance may be lower or higher than
the performance data quoted.

The performance data quoted represents past performance, which is no guarantee
of future results. Investment return and principal value will fluctuate, and
shares, when redeemed, may be worth more or less than their original cost.

NAV results represent the percent change in net asset value per share. Returns
would have been lower had sales charges been reflected. POP returns reflect
deduction of maximum 4.50% 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 March 1, 2014, 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.

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 1.00%, 1.90%,
    and 0.79% for Class A, Class C, and Class Y shares, respectively, multiplied
    by the average account value over the period, multiplied by 184/366.

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 | 10/31/12

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. The Fund is registered under the
Investment Company Act of 1940 as a diversified, open-end management investment
company. The investment objective of the Fund is to provide current income from
an investment grade portfolio with due regard to preservation of capital and
prudent investment risk.

The Fund offers three classes of shares designated as 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 identical rights (based on relative
net asset values) to assets and liquidation proceeds. Share classes can bear
different rates of class-specific fees and expenses such as transfer agent and
distribution fees. Differences in class-specific fees and expenses will result
in differences in net investment income and, therefore, the payment of different
dividends from net investment income earned by each class. The Amended and
Restated Declaration of Trust of the Fund gives the Board the flexibility to
specify either per-share voting or dollar-weighted voting when submitting
matters for shareholder approval. Under per-share voting, each share of a class
of the Fund is entitled to one vote. Under dollar-weighted voting, a
shareholder's voting power is determined not by the number of shares owned, but
by the dollar value of the shares on the record date. Each share class has
exclusive voting rights with respect to matters affecting only that class,
including with respect to the distribution plan for that class. There is no
distribution plan for Class Y shares.

The Fund's financial statements have been prepared in conformity with U.S.
generally accepted accounting principles that require the management of the Fund
to, among other things, make estimates and assumptions that affect the reported
amounts of assets and liabilities, the disclosure of contingent assets and
liabilities at the date of the financial statements, and the reported amounts of
income, expenses and gain or loss on investments during the reporting period.
Actual results could differ from those estimates.

The following is a summary of significant accounting policies followed by the
Fund in the preparation of its financial statements, which are consistent with
those policies generally accepted in the investment company industry:

                Pioneer Global Aggregate Bond Fund | Annual Report | 10/31/12 51


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. Fixed income
    securities with remaining maturity of more than sixty days are valued at
    prices supplied by independent pricing services, which consider such factors
    as market prices, market events, quotations from one or more brokers,
    Treasury spreads, yields, maturities and ratings. Valuations may be
    supplemented by dealers and other sources, as required. Equity securities
    that have traded on an exchange are valued at the last sale price on the
    principal exchange where they are traded. Equity securities that have not
    traded on the date of valuation, or securities for which sale prices are not
    available, generally are valued using the mean between the last bid and
    asked prices. Short-term fixed income securities with remaining maturities
    of sixty days or less generally are valued at amortized cost.

    Securities for which independent pricing services are unable to supply
    prices or for which market prices and/or quotations are not readily
    available or are considered to be unreliable are valued using fair value
    methods pursuant to procedures adopted by the Board of Trustees. The Fund
    may use fair value methods if it is determined that a significant event has
    occurred after the close of the exchange or market on which the security
    trades and prior to the determination of the Fund's net asset value.
    Examples of a significant event might include political or economic news,
    corporate restructurings, natural disasters, terrorist activity or trading
    halts. Thus, the valuation of the Fund's securities may differ from exchange
    prices.

    At October 31, 2012, there were no securities that were valued using fair
    value methods (other than securities valued using prices supplied by
    independent pricing services). Inputs used when applying fair value methods
    to value a security may include credit ratings, the financial condition of
    the company, current market conditions and comparable securities.

    Principal amounts of mortgage-backed securities are adjusted for monthly
    paydowns. Premiums and discounts related to certain mortgage-backed
    securities are amortized or accreted in proportion to the monthly paydowns.
    All discounts/premiums on debt securities are accreted/amortized for
    financial reporting purposes over the life of the respective securities, and
    such accretion/amortization is included in interest income.

52 Pioneer Global Aggregate Bond Fund | Annual Report | 10/31/12


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

    Gains and losses on sales of investments are calculated on the identified
    cost method for both financial reporting and federal income tax purposes.

B.  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 may enter into forward foreign currency contracts (contracts) for
    the purchase or sale of a specific foreign currency at a fixed price on a
    future date. 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).

                Pioneer Global Aggregate Bond Fund | Annual Report | 10/31/12 53


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. As of
    October 31, 2012, the Fund did not have any interest and penalties related
    to unrecognized tax positions, which, if applicable, would be recorded as an
    income tax expense in the Statement of Operations. Tax years for the prior
    three fiscal years are subject to examination by federal and state tax
    authorities.

    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, 2012, the Fund reclassified $15,588 to increase distributions
    in excess of net investment income and $15,588 to increase accumulated net
    realized gain on investments and foreign currency transactions to reflect
    permanent book/tax differences. The reclassification has no impact 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,
    2012 and October 31, 2011 were as follows:



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

    Total                                                            $1,839,654

54 Pioneer Global Aggregate Bond Fund | Annual Report | 10/31/12


    The difference between book-basis and tax-basis net unrealized appreciation
    is attributable to the mark to market on forward foreign currency and
    futures contracts and interest accruals on preferred stock.

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 $2,114 in underwriting commissions on the sale of Class A shares
    during the year ended October 31, 2012.

F.  Class Allocations

    Income, common expenses and realized and unrealized gains and losses are
    calculated at the Fund level and allocated daily to each class of shares
    based on its 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 shares of the Fund, respectively (see
    Note 4). Class Y shares do not pay distribution fees. All expenses and fees
    paid to the transfer agent, Pioneer Investment Management Shareholder
    Services, Inc. (PIMSS), for its services are allocated among the classes of
    shares 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 and at the same time, except that net
    investment income dividends to Class A, Class C and Class Y shares can
    reflect different transfer agent and distribution expense rates.

G.  Risks

    At times, the Fund's investments may represent industries or industry
    sectors that are interrelated or have common risks, making the Fund 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 investments 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 contains unaudited information regarding the Fund's
    principal risks. Please refer to that document when considering the Fund's
    principal risks.

                Pioneer Global Aggregate Bond Fund | Annual Report | 10/31/12 55


    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.

H.  Securities Lending

    The Fund may lend securities in its portfolio to certain broker-dealers or
    other institutional investors. When entering into a securities loan
    transaction, the Fund typically receives cash collateral from the borrower
    equal to at least the value of the securities loaned, which is invested in
    temporary investments. Credit Suisse AG, New York Branch, as the Fund's
    securities lending agent, manages the Fund's securities lending collateral.
    The income earned on the investment of collateral is shared with the
    borrower and the lending agent in payment of any rebate due to the borrower
    with respect to the securities loan, and in compensation for the lending
    agent's services to the Fund. The Fund also continues to receive payments in
    lieu of dividends or interest on the securities loaned. Gain or loss on the
    value of the loaned securities that may occur during the term of the loan
    will be for the account of the Fund. The amount of the collateral is
    required to be adjusted daily to reflect any price fluctuation in the value
    of the loaned securities. If the required market value of the collateral is
    less than the value of the loaned securities, the borrower is required to
    deliver additional collateral for the account of the Fund prior to the close
    of business on that day. The Fund has the right, under the lending
    agreement, to terminate the loan and recover the securities from the
    borrower with prior notice. The Fund is required to return the cash
    collateral to the borrower and could suffer a loss if the value of the
    collateral, as invested, has declined. At October 31, 2012, the Fund had no
    securities on loan.

I.  Futures Contracts

    The Fund may enter into futures transactions to hedge against changes in
    interest rates, securities prices and currency exchange rates or to seek to
    increase total return. Futures contracts are types of derivatives. All
    futures contracts entered into by the Fund are traded on a futures exchange.
    Upon entering into a futures contract, the Fund is required to deposit with
    a broker an amount of cash or securities equal to the minimum "initial
    margin" requirements of the associated futures exchange. Subsequent payments
    for futures contracts ("variation margin") are paid or received by the Fund,
    depending on the daily fluctuation in the value of the contracts, and are
    recorded by the Fund as unrealized gains or losses. When the contract is
    closed, the Fund realizes a gain or loss equal to the difference

56 Pioneer Global Aggregate Bond Fund | Annual Report | 10/31/12


    between the opening and closing value of the contract as well as any
    fluctuation in foreign currency exchange rates where applicable. Futures
    contracts are subject to market risk, interest rate risk and currency
    exchange rate risk. Changes in value of the contracts may not directly
    correlate to the changes in value of the underlying securities. These risks
    may decrease the effectiveness of the Fund's hedging strategies and
    potentially result in a loss. With futures, there is minimal counterparty
    credit risk to the Fund since futures are exchange-traded and the exchange's
    clearinghouse, as counterparty to all exchange-traded futures, guarantees
    the futures against default. During the year ended October 31, 2012, the
    Fund had 7 outstanding futures contracts.

    At October 31, 2012, open futures contracts were as follows

================================================================================


J.  Repurchase Agreements

    With respect to repurchase agreements entered into by the Fund, the value of
    the underlying securities (collateral), including accrued interest, is
    required to be equal to or in excess of the repurchase price. The collateral
    for all repurchase agreements is held in safekeeping in the customer-only
    account of the Fund's custodian or a subcustodian of the Fund. The Fund's
    investment adviser, Pioneer Investment Management, Inc. (PIM), is
    responsible for determining that the value of the collateral remains at
    least equal to the repurchase price.

2. Management Agreement

PIM, a wholly-owned indirect subsidiary of UniCredit, 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 contractually agreed to limit ordinary operating expenses of the Fund to
the extent required to reduce Fund expenses to 1.00%, 1.90% and 0.75% of the
average daily net assets attributable to Class A, Class C and Class Y shares,
respectively. Fees waived and expenses reimbursed during the year ended October
31, 2012 are reflected on the Statement of Operations. These expense limitations
are in effect through March 1, 2014. There can be no assurance that PIM will
extend the expense limitation agreement for a class of shares beyond the date
referred to above.

                Pioneer Global Aggregate Bond Fund | Annual Report | 10/31/12 57


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 as administrative reimbursements. Included in
"Due to affiliates" reflected on the Statement of Assets and Liabilities is
$14,623 in management fees, administrative costs and certain other
reimbursements payable to PIM at October 31, 2012.

Effective March 5, 2012, PIM has retained Brown Brothers Harriman & Co. to
provide certain sub-administration and accounting services to the fund.

3. Transfer Agent

PIMSS, a wholly owned indirect subsidiary of UniCredit, provides substantially
all transfer agent and shareowner services to the Fund at negotiated rates.

In addition, the Fund reimburses PIMSS for out-of-pocket expenses incurred by
PIMSS related to shareholder communications activities such as proxy and
statement mailings, outgoing phone calls and omnibus relationship contracts. For
the year ended October 31, 2012, such out-of-pocket expenses by class of shares
were as follows:



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

--------------------------------------------------------------------------------
                                                                      
Class A                                                                  $10,224

Class Y                                                                    1,242
--------------------------------------------------------------------------------
    Total                                                                $14,400
================================================================================


Included in "Due to affiliates" reflected on the Statement of Assets and
Liabilities is $8,001 in transfer agent fees and out-of-pocket reimbursements
payable to PIMSS at October 31, 2012.

4. Distribution Plan

The Fund has adopted a Distribution Plan pursuant to Rule 12b-1 of the Invest-
ment Company Act of 1940 with respect to its Class A and Class C shares.
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 also 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 $350 in distribution fees payable to PFD
at October 31, 2012.

                Pioneer Global Aggregate Bond Fund | Annual Report | 10/31/12 58


In addition, redemptions of each class of shares (except Class Y shares) may be
subject to a contingent deferred sales charge (CDSC). A CDSC of 1.00% may be
imposed on redemptions of certain net asset value purchases of Class A shares
within 12 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. Shares purchases as part of an exchange remain
subject to any CDSC that applied to the original purchase of those shares. There
is no CDSC for Class Y shares. Proceeds from the CDSCs are paid to PFD. For the
year ended October 31, 2012, CDSCs in the amount of $705 were paid to PFD.

5. Expense Offset Arrangements

The Fund has entered into certain expense offset arrangements with PIMSS which
may result in a reduction in the Fund's total expenses due to interest earned on
cash held by PIMSS. For the year ended October 31, 2012, the Fund's expenses
were not reduced under such arrangements.

6. Forward Foreign Currency Contracts

At October 31, 2012, the Fund had entered into various forward foreign currency
contracts that obligate the Fund to deliver or take delivery of currencies at
specified future maturity dates. Alternatively, prior to the settlement date of
a forward foreign currency contract, the Fund may close out such contract by
entering into an offsetting contract. The average value of contracts open during
the year ended October 31, 2012 was $773,608.

8. Line of Credit Facility

The Fund, along with certain other funds in the Pioneer Family of Funds (the
Funds), participates in a 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 the amount available under the facility or
the limits set for borrowing by the Fund's prospectus and the 1940 Act. The
credit facility in effect until January 20, 2012 was in the amount of $165
million. Under such facility, interest on borrowings was payable at the higher
of the London Interbank Offered Rate (LIBOR) on the borrowing date plus 1.25% on
an annualized basis or the Federal Funds Rate on the borrowing date plus 1.25%
on an annualized basis. The credit facility in effect as of February 15, 2012 is
in the amount of $215 million. Under such facility, depending on the type of
loan, interest on borrowings is payable at LIBOR plus 0.90% on an annualized
basis, or the Alternate Base Rate, which is the greater of (a) the facility's
administrative agent's daily announced prime rate on the borrowing date, (b) 2%
plus the Federal Funds Rate on the borrowing date and (c) 2% plus the overnight
Euro dollar rate on the borrowing date. The Funds pay an annual commitment fee
to participate in a credit facility. The commitment fee is allocated among
participating Funds based on an allocation schedule set forth in the credit
agreement. For the year ended October 31, 2012, the Fund had no borrowings under
a credit facility.

Report of Independent Registered Public Accounting Firm

To the Board of Trustees of Pioneer Series Trust VII and the Shareowners of
Pioneer Global Aggregate Bond Fund
--------------------------------------------------------------------------------
We have audited the accompanying statement of assets and liabilities, including
the schedule of investments, of Pioneer Global Aggregate Bond Fund (the "Fund")
(one of the portfolios constituting the Pioneer Series Trust VII), as of October
31, 2012, 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, 2012, by correspondence with the custodian
and brokers. 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 Aggregate Bond Fund at October 31, 2012, 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 indi- cated 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.

there were no services provided to an affiliate that required
the Fund's audit committee pre-approval.

principal accountant's engagement to audit the registrant's financial statements
for the most recent fiscal year that were attributed to work performed by

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.

previously defined, totaled approximately $16,580 in 2012
and $16,580 in 2011.

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.
