President's Letter

Dear Shareholder,

Through the first three quarters of 2015, global markets experienced pockets of
higher-than-average volatility due to significant cross-currents from different
geographic regions. All year, investors focused on the Federal Reserve System's
(the Fed's) deliberations over when to begin normalizing interest rates.
However, while there were signs of gradual economic improvement in the U.S.,
economies abroad increasingly diverged. In June, for example, investors grew
concerned about the debt crisis in Greece. That news, in turn, was followed by
evidence of an economic slowdown in China, which only served to exacerbate
existing worries about growth trends in the emerging markets, a segment of the
global economy already being negatively impacted by slumping commodity prices,
including the price of crude oil, which has been in near-steady decline for
almost a year. Through September 30, 2015, the pockets of heightened market
volatility alluded to above had resulted in the Standard & Poor's 500 Index
turning in a negative (-5.27%) return over the first nine months of the year.
However, the S&P 500 recovered nicely in October, returning 8.43% for the month,
which boosted the index's year-to-date return into positive territory, at 2.71%.

Despite the headwinds still vexing the global economy, our longer-term view of
the U.S. economy has remained positive. Economic conditions in the U.S. have
generally been constructive, based largely on improvements in employment
statistics and an uptick in the housing sector, which has aided the consumer
side of the economy, where household spending has been rising modestly. U.S.
consumers also stand to benefit, potentially, from lower energy prices as the
winter weather approaches. We continue to believe the U.S. economy remains on
a slow, steady growth trend, and that it is unlikely to be disrupted by a slow
pace of interest-rate normalization by the Fed.

Pioneer Investments believes that investors in today's environment can
potentially benefit from the consistent and disciplined investment approach we
have used since our founding in 1928. We focus on identifying value across
global markets using proprietary research, careful risk management, and a
long-term perspective. Our ongoing goal is to produce compelling returns
consistent with the stated objectives of our investment products, and with our
shareowners' expectations. We believe our shareowners can benefit from the
experience and tenure of our investment teams as well as the insights generated
from our extensive research process.

2 Pioneer Global High Yield Fund | Annual Report | 10/31/15


As always, and particularly during times of market uncertainty, we encourage you
to work with your financial advisor to develop an overall investment plan that
addresses both your short- and long-term goals, and to implement such a plan in
a disciplined manner.

We greatly appreciate your trust in us in the past and look forward to
continuing to serve you in the future.

Sincerely,

/s/ Lisa M. Jones

Portfolio Management Discussion | 10/31/15

Credit-sensitive securities, including high-yield corporate bonds and emerging
markets debt, struggled over most of the 12-month period ended October 31, 2015,
as investors' concerns about the declining prices of oil and other commodities,
and mounting fears of global economic weakening, negatively affected the
markets. In the following interview, Andrew Feltus and Tracy Wright discuss the
market environment and the performance of Pioneer Global High Yield Fund during
the 12-month period. Mr. Feltus, Director of High Yield and Bank Loans, a senior
vice president and a portfolio manager at Pioneer, is lead manager of the Fund,
and Ms. Wright, a senior vice president and portfolio manager at Pioneer, is the
co-manager of the Fund. Together, they are responsible for the day-to-day
management of the Fund.

Q    How did the Fund perform during the 12-month period ended October 31, 2015?

A    Pioneer Global High Yield Fund's Class A shares returned -6.36% at net
     asset value during the 12-month period ended October 31, 2015, while the
     Fund's benchmarks, the Barclays Global High Yield Index (the Barclays
     Index) and the Bank of America Merrill Lynch (BofA ML) High Yield Master II
     Index, each returned -2.05%. During the same period, the average return of
     the 656 mutual funds in Lipper's High Yield Funds category was -2.24%, and
     the average return of the 773 mutual funds in Morningstar's High Yield Bond
     Funds category was -2.09%.

Q    How would you describe the investment environment in the global high-yield
     markets during the 12-month period ended October 31, 2015?

A    Declining commodity prices - especially of crude oil - and concerns about
     global economic growth trends dragged down the high-yield bond market over
     the 12-month period. The domestic high-yield corporate bond market, with
     its large exposures to debt issued by energy firms as well as by metals and
     mining companies, was hit particularly hard. Emerging markets securities
     also sold off significantly, as many emerging economies are heavily
     dependent on exports of oil and other commodities. European high-yield
     bonds, however, were less exposed to commodity prices and tended to hold up
     somewhat better (in local currency values), especially in light of the
     European Central Bank's (ECB's) easing of monetary policy during the
     period; however, the weakness of the euro in world currency markets had a
     negative impact on European high-yield's performance on an unhedged basis.

    At the start of the 12-month period, during the fourth quarter of 2014,
    declining oil prices tended to pull down both the emerging and domestic
    high-yield markets, as both had relatively large exposures to oil-related

4 Pioneer Global High Yield Fund | Annual Report | 10/31/15


     industries. In fact, bonds issued by energy companies accounted for between
     roughly 12% to 16% of domestic high-yield corporate bonds, and as much as
     40% of emerging markets corporate debt. Early in 2015, energy-related
     bonds tended to show some improvement as oil prices firmed, but oil began
     declining again at mid-year and the price of crude continued to drop all
     the way through the end of the period. This, once again, had a negative
     effect on both domestic high-yield bonds and emerging markets debt. At the
     same time, evidence of slowing economic growth trends in China raised still
     more concerns, this time about possible contagion effects a slowdown in
     China may have on many emerging markets economies, and on the global
     economic growth outlook in general. Adding to the negative factors
     affecting the high-yield markets were growing expectations that the U.S.
     Federal Reserve System (the Fed), sooner rather than later, would begin
     raising short-term interest rates for the first time in nearly a decade.

     While emerging markets bonds struggled overall during the 12-month period,
     a credit-rating downgrade on Russian debt resulted in the addition of those
     securities to emerging markets benchmarks, which turned out to be a
     positive development. After the downgrade, Russian debt instruments - both
     sovereigns and corporates - rallied and lent support to some market
     indices.

     In the final month of the period, the domestic high-yield market did stage
     a rally, with one of the Fund's benchmarks, the BofA ML High Yield Master
     II Index, rising by 2.73% for the month after the Fed announced in
     September that it would again delay any move to increase short-term
     interest rates.

Q    Which factors had the biggest effects on the Fund's performance relative to
     the high-yield benchmarks during the 12-month period ended October 31,
     2015?

A    The Fund's benchmark-relative underperformance during the period was due
     primarily to overall security selection results. In particular, security
     selection results in the energy sector and among the portfolio's emerging
     markets debt holdings acted as major drags on relative returns. The
     negative effects of adverse security selection offset the positive impact
     of our heavy emphasis on the U.S. dollar in the portfolio, as the dollar
     appreciated in value versus most foreign currencies during the period. In
     addition, the Fund's non-benchmark exposures to floating-rate bank loans
     and insurance-linked securities contributed to benchmark-relative results.

     With regard to individual positions, several of the Fund's investments in
     emerging markets debt detracted significantly from relative performance.
     Notably, a position in OAS, a Brazilian construction company that filed for
     bankruptcy protection in January 2015, hurt relative returns. The effects
     of the OAS bankruptcy filing spread and undermined the performance of bonds
     of other construction companies located in the emerging markets,

                     Pioneer Global High Yield Fund | Annual Report | 10/31/15 5


     including ICA, a Mexican company whose bonds the portfolio also owned. In
     addition, the Fund's investment in the debt of Pacific Rubicales Energy, a
     Colombia-based corporation, was a detractor from relative performance as
     the bonds sold off after shareholders blocked the planned sale of the
     corporation to a Mexican firm.

     On the positive side, the portfolio did have several positions in the
     domestic high-yield market that supported the Fund's benchmark-relative
     results during the period, including the bonds of Lantheus Medical, a
     corporation which provides diagnostic medical imaging services that was
     able to refinance its debt after an initial public stock offering. In the
     emerging markets, a number of the Fund's Argentina-based holdings performed
     well on investors' expectations of government reforms in the country. Some
     of the stronger performers in the Fund's portfolio during the period were
     securities issued by IRSA, an Argentinian real estate company, and Banco
     Galicia, a financial services company.

Q    Did the Fund invest in any derivative securities during the 12-month period
     ended October 31, 2015? If so, what impact did those investments have on
     benchmark-relative results?

A    Yes, we did invest the Fund in some forward currency contracts as part of
     our strategy to overweight the portfolio to the U.S. dollar. The use of
     these contracts had a positive effect on the Fund's results as the dollar
     strengthened against most foreign currencies.

Q    What factors affected the Fund's dividend* during the 12-month period ended
     October 31, 2015?

A    The Fund's dividend was reduced in late 2014, but it has remained stable
     during the first 10 months of 2015. During the full 12-month period, yield
     spreads (or yield differences) between higher-rated and lower-rated bonds
     have widened, and high-yield bonds have underperformed. We think this
     development may afford us the potential to reinvest the Fund's assets in
     securities with higher coupon rates in the future, even though we are still
     in a low-interest-rate environment.

*   Dividends are not guaranteed.

Q    What is your investment outlook?

A    As the Fund enters a new fiscal year, a major factor influencing the
     prospects for high-yield securities is how soon the Fed tightens monetary
     policy by raising short-term interest rates. The Fed's decision in 2014 to
     end its monthly quantitative easing bond purchases contributed to the
     volatility in the high-yield bond market, and we believe raising short-term
     rates may have a similar effect.

     Overall, we have a positive outlook for high-yield securities. At current
     prices, we think domestic high-yield bonds offer real value, especially
     after the volatility of the past year, which has increased the relative
     attractiveness of the asset class. Yield spreads have widened substantially
     and are more than compensating investors for default risk, which remains
     well below the historic 4% long-term average for the high-yield market; we
     think even spread levels on energy-related corporate bonds more than
     compensate investors for current risk factors.

     Corporate issuers, meanwhile, have generally maintained solid profit
     margins and healthy balance sheets, and continue to have good access to
     capital. Additionally, the high levels of leveraged buyout activity seen in
     the recent past have receded, which should be a positive factor for the
     bond market going forward. Finally, we think the prospects for emerging
     markets debt, and for domestic energy as well as mining and metals bond
     issuers can only improve if there is strengthening in the prices of oil and
     other commodities.

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

Investments in high-yield or lower-rated securities are subject to greater-than-
average price volatility, illiquidity and possibility of default.

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.

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

Prepayment risk is the chance that an issuer may exercise its right to repay its
security, if falling interest rates prompt the issuer to do so. 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.

The Fund 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 Fund may use derivatives, such as options, futures, inverse floating rate
obligations, swaps, and others, which can be illiquid, may disproportionately
increase losses, and have a potentially large impact on Fund performance.
Derivatives may have a leveraging effect on the Fund.

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.

Before investing, consider the product's investment objectives, risks, charges
and expenses. Contact your advisor or Pioneer Investments for a prospectus or
summary prospectus containing this information. Read it carefully.

Any information in this shareholder report regarding market or economic trends

Index Definitions
--------------------------------------------------------------------------------
The Barclays Global High Yield Index is an unmanaged index that provides a
broad-based measure of the global high-yield fixed-income markets. The index
represents the union of the Barclays U.S. High-Yield, Barclays Pan-European
High-Yield, Barclays U.S. Emerging Markets High-Yield, and Barclays Pan-
European Emerging Markets High-Yield Indices. The BofA ML High Yield Master II
Index is an unmanaged, 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 11-13.

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.

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). "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

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.

Performance shown for Class Y shares for periods prior to the inception of Class
Y shares on December 28, 2005, is the net asset value 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. For the period beginning December 28, 2005,
the actual performance of Class Y shares is reflected. Class Y shares are not
subject to sales charges and are available for limited groups of eligible
investors, including institutional investors. All results are historical and
assume the reinvestment of dividends and capital gains. Other share classes are
available for which performance and expenses will differ.

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

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

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 net expense ratio of 1.17%,
     1.87%, and 0.87% for Class A, Class C and Class Y shares, respectively,
     multiplied by the average account value over the period, multiplied by
     184/365 (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 | 10/31/15

1. Organization and Significant Accounting Policies

Pioneer Global High Yield Fund (the Fund) is one of three portfolios comprising
Pioneer Series Trust VII (the Trust), 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 three classes of shares designated as Class A, Class C and Class
Y shares. Class B shares were converted to Class A shares as of the close of
business on November 10, 2014. Class Z shares converted to Class Y shares as of
the close of business on August 7, 2015. 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 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:

                    Pioneer Global High Yield Fund | Annual Report | 10/31/15 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 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. 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. If price information is not available from
     Loan Pricing Corporation, or if the price is deemed to be unreliable, price
     information will be obtained from an alternate loan interest pricing
     service. If no reliable price quotes are available from either the primary
     or alternative pricing service, broker quotes will be solicited.
     Event-linked bonds are valued at the bid price obtained from an independent
     third party pricing service. Other insurance-linked securities may be
     valued at the bid price obtained from an independent pricing service, or
     through a third party using a pricing matrix, insurance industry valuation
     models, or other fair value methods or techniques to provide an estimated
     value of the instrument. 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. Shares of
     money market mutual funds are valued at such funds' net asset value. Cash
     may include overnight time deposits at approved financial institutions.

     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 market prices and/or quotations are
     not readily available or are considered to be unreliable are valued by a
     fair valuation team comprised of certain personnel of Pioneer Investment
     Management, Inc. (PIM), the Fund's investment adviser, pursuant to
     procedures adopted by the Fund's Board of Trustees. PIM's fair valuation
     team uses fair value methods approved by the Valuation Committee of the
     Board of Trustees. PIM's fair value valuation team is responsible for

52 Pioneer Global High Yield Fund | Annual Report | 10/31/15


     monitoring developments that may impact fair valued securities and for
     discussing and assessing fair values on an ongoing basis, and at least
     quarterly, with the Valuation Committee of the Board of Trustees.

     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. The Trust 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 Trust'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 Trust's securities may differ significantly from exchange prices and
     such differences could be material.

     At October 31, 2015, ten securities were valued using fair value methods
     (in addition to securities valued using prices supplied by independent
     pricing services, broker-dealers or through a third party using an
     insurance industry valuation model) representing 1.0% of net assets.

B.   Investment Income and Transactions

     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 purchase prices of 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.

C.   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.

                    Pioneer Global High Yield Fund | Annual Report | 10/31/15 53


     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 the market prices of those securities but are
     included with the net realized and unrealized gain or loss on investments.

D.   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 appreciation or depreciation
     is recorded in the Fund's financial statements. The Fund records realized
     gains and losses at the time a 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).

E.   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 net taxable income and net realized capital gains, if any, to
     its shareowners. Therefore, no provision for federal income taxes is
     required. As of October 31, 2015, the Fund did not accrue any interest or
     penalties with respect to uncertain tax positions, which, if applicable,
     would be recorded as an income tax expense in the Statement of Operations.
     Tax returns filed within the prior three years remain subject to
     examination by federal and state tax authorities.

     The amount and character of income and capital gain distributions to
     shareowners are determined in accordance with federal income tax rules,
     which may differ from U.S. generally accepted accounting principles.
     Distributions in excess of net investment income or net realized gains are
     temporary overdistributions for financial statement purposes resulting from
     differences in the recognition or classification of income or distributions
     for financial statement and tax purposes. Capital accounts within the
     financial statements are adjusted for permanent book/tax differences to
     reflect tax character, but are not adjusted for temporary differences.

54 Pioneer Global High Yield Fund | Annual Report | 10/31/15


     At October 31, 2015, the Fund reclassified $13,907,516 to increase
     distributed in excess of net investment income and $13,907,516 to
     decrease accumulated net realized loss on investments, written options
     and foreign currency transactions to reflect permanent book/tax
     differences. These adjustments have no impact on net assets or the
     results of operations.

     At October 31, 2015, the Fund was permitted to carry forward indefinitely
     $14,957,489 of short-term losses and $147,107,113 of long-term losses under
     the Regulated Investment Company Modernization Act of 2010 without
     limitation. Additionally, at October 31, 2015, 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,
     2015 and October 31, 2014 were as follows:



     ---------------------------------------------------------------------------
                                                   2015                     2014
     ---------------------------------------------------------------------------
                                                              
     Distributions paid from:
     Ordinary income                        $59,414,496             $100,787,602
     Return of capital                       10,222,285                4,607,391
     ---------------------------------------------------------------------------
         Total                              $69,736,781             $105,394,993
     ===========================================================================


     The following shows the components of distributable earnings on a federal
     income tax basis at October 31, 2015:



     ---------------------------------------------------------------------------
                                                                            2015
     ---------------------------------------------------------------------------
                                                               
     Distributable earnings:
     Capital loss carryforward                                    $(397,912,964)
     Current year dividend payable                                     (668,299)
     Net unrealized depreciation                                   (129,935,691)
     ---------------------------------------------------------------------------
         Total                                                    $(528,516,954)
     ===========================================================================


     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, partnerships, interest on defaulted bonds, and interest
     accruals on preferred stock.

F.   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 $28,208 in underwriting commissions on the sale of
     Class A shares during the year ended October 31, 2015.

                    Pioneer Global High Yield Fund | Annual Report | 10/31/15 55


G.   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 Fund's transfer agent 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.

H.   Insurance Linked Securities (ILS)

     Event-linked bonds are floating rate debt obligations for which the return
     of principal and the payment of interest are contingent on the
     non-occurrence of a pre-defined "trigger" event, such as a hurricane or an
     earthquake of a specific magnitude. The trigger event's magnitude may be
     based on losses to a company or industry, industry indexes or readings of
     scientific instruments, or may be based on specified actual losses. If a
     trigger event, as defined within the terms of an event-linked bond occurs,
     the fund may lose a portion or all of its accrued interest and/or principal
     invested in such event-linked bond. The fund is entitled to receive
     principal and interest payments so long as no trigger event occurs of the
     description and magnitude specified by the instrument. In addition to the
     specified trigger events, event-linked bonds may expose the Fund to other
     risks, including but not limited to issuer (credit) default, adverse
     regulatory or jurisdictional interpretations and adverse tax consequences.

     The Fund's investments in ILS may include special purpose vehicles ("SPVs")
     or similar instruments structured to comprise a portion of a reinsurer's
     catastrophe-oriented business, known as quota share instruments (sometimes
     referred to as reinsurance sidecars), or to provide reinsurance relating to
     specific risks to insurance or reinsurance companies through a
     collateralized instrument, known as collateralized reinsurance. Structured
     reinsurance investments also may include industry loss warranties ("ILWs"),
     are subject to the same risks as event-linked bonds. In addition, because
     quota share

56 Pioneer Global High Yield Fund | Annual Report | 10/31/15


     instruments represent an interest in a basket of underlying reinsurance
     contracts, the Fund has limited transparency into the individual underlying
     contracts and therefore must rely upon the risk assessment and sound
     underwriting practices of the issuer. Accordingly, it may be more difficult
     for PIM to fully evaluate the underlying risk profile of the Fund's
     investment in quota share instruments and therefore place the Fund's assets
     at greater risk of loss than if PIM had more complete information.

     Quota share instruments and other structured reinsurance instruments
     generally will be considered illiquid securities by the Fund. These
     securities may be difficult to purchase, sell or unwind. Illiquid
     securities also may be difficult to value. If the Fund is forced to sell an
     illiquid asset, the Fund may be forced to sell at a loss.

I.   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.

J.   Option Writing

     The Fund may write put and covered call options to seek to increase total
     return. When an option is written, the Fund receives a premium and becomes
     obligated to purchase or sell the underlying security at a fixed price,
     upon the exercise of the option. When the Fund writes an option, an amount
     equal to the premium received by the Fund is recorded as a liability and is
     subsequently adjusted to the current value of the option written. Premiums
     received from writing options that expire unexercised are treated by the
     Fund on the expiration date as realized gains from investments. The
     difference between the premium and the amount paid on effecting a closing
     purchase transaction, including brokerage commissions, is also treated as a
     realized

                    Pioneer Global High Yield Fund | Annual Report | 10/31/15 57


     gain, or, if the premium is less than the amount paid for the closing
     purchase transaction, as a realized loss. If a call option is exercised,
     the premium is added to the proceeds from the sale of the underlying
     security in determining whether the Fund has realized a gain or loss. The
     Fund as writer of an option bears the market risk of an unfavorable change
     in the price of the security underlying the written option.

     The average value of contracts open during the year ended October 31, 2015
     was $(7). There were no written options outstanding at October 31, 2015.

     Transactions in written options for the year ended October 31, 2015 are
     summarized as follows:

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, 2015, the effective management fee (excluding waivers and/or
assumption of expenses) was equivalent to 0.66% of the Fund's average daily net
assets.

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
$54,155 in management fees, administrative costs and certain other
reimbursements payable to PIM at October 31, 2015.

3. Transfer Agent

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


Included in "Due to affiliates" reflected on the Statement of Assets and
Liabilities is $295,105 in transfer agent fees and out-of-pocket reimbursements
payable to PIMSS at October 31, 2015.

4. 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 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 $24,719 in distribution fees payable to
PFD at October 31, 2015.

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. Redemptions of Class C shares
within 12 months 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, 2015, CDSCs in the amount
of $11,423 were paid to PFD.

5. 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 June 9, 2015 is in the amount of $215 million.
As of June 9, 2015, the facility was in the amount of $240 million. Under such
facility, depending on the type of loan, interest on borrowings is payable at
the London Interbank Offered Rate (LIBOR) plus 0.85% 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
eurodollar rate on the borrowing date. The Funds pay an annual commitment fee to
participate in the 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, 2015, the Fund had no borrowings under
the credit facility.

6. Expense Offset Arrangements

The Fund 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, 2015, the Fund's expenses
were not reduced under such arrangements.

7. Bridge Loan Commitments

Bridge loans are designed to provide temporary or "bridge" financing to a
borrower pending the sale of identified assets or the arrangement of longer term
loans or the issuance or sale of debt obligations.

As of October 31, 2015, the Fund had one bridge loan commitment of $5,007,826,
which could be extended at the option of the borrower, pursuant to the following
loan agreement:

9. Assets and Liabilities Offsetting

The Fund has entered into an International Swaps and Derivatives Association,
Inc. Master Agreement ("ISDA Master Agreement") or similar agreement with
substantially all its derivative counterparties. An ISDA Master Agreement is a
bilateral agreement between the Fund and a counterparty that governs the trading
of certain OTC derivatives and typically contains, among other things, close-out
and set-off provisions which apply upon the occurrence of event of a default
and/or termination event as defined under the relevant ISDA Master Agreement.
The ISDA Master Agreement may also give a party the right to terminate all
transactions traded under such agreement if, among other things, there is
deterioration in the credit quality of the other party. Upon an event of default
or a termination of the ISDA Master Agreement, the non-defaulting party has the
right to close out all transactions under such agreement and to net amounts owed
under each transaction to determine one net amount payable by one party to the
other. The right to close out and net payments across all transactions under the
ISDA Master Agreement could result in a reduction of the Fund's credit risk to
its counterparty equal to any amounts payable by the Fund under the applicable
transactions, if any. However, the

                    Pioneer Global High Yield Fund | Annual Report | 10/31/15 61


Fund's right to setoff may be restricted or prohibited by the bankruptcy or
insolvency laws of the particular jurisdiction to which a specific ISDA
counterparty is subject.

The collateral requirements for derivatives transactions under an ISDA Master
Agreement are governed by a credit support annex to the ISDA Master Agreement.
Collateral requirements are generally determined at the close of business each
day and are typically based on changes in market values for each transaction
under an ISDA Master Agreement and netted into one amount for such agreement.
Generally, the amount of collateral due from or to a counterparty is subject to
threshold (a "minimum transfer amount") before a transfer is required, which may
vary by counterparty. Collateral pledged for the benefit of the Fund and/or
counterparty is held in segregated accounts by the Fund's custodian and cannot
be sold, re-pledged, assigned or otherwise used while pledged. Cash that has
been segregated to cover the Fund's collateral obligations, if any, will be
reported separately in the Statement of Assets and Liabilities as "Futures
collateral", "Swap Collateral" or "Deposit with broker." Securities pledged by
the Fund as collateral, if any, are identified as such in the Schedule of
Investments.

Financial instruments subject to an enforceable master netting agreement such as
an ISDA Master Agreement have been offset on the Statement of Assets and
Liabilities. The following charts show gross assets and liabilities of the Fund

10. Additional Disclosures about Derivative Instruments and Hedging Activities:

The Fund's use of derivatives subjects it to the following risks:

Interest rate risk relates to the fluctuations in the value of interest-bearing
securities due to changes in the prevailing levels of market interest rates.

Credit risk relates to the ability of the issuer of a financial instrument to
make further principal or interest payments on an obligation or commitment that
it has to the Fund.

Foreign exchange rate risk relates to fluctuations in the value of an asset or
liability due to changes in currency exchange rates.

Equity risk relates to the fluctuations in the value of financial instruments as
a result of changes in market prices (other than those arising from interest
rate risk or foreign exchange risk), whether caused by factors specific to an
individual investment, its issuer, or all factors affecting all instruments
traded in a market or market segment.

Commodity risk relates to the risk that the value of a commodity or commodity
index will fluctuate based on increases or decreases in the commodities market
and factors specific to a particular industry or commodity.

Report of Independent Registered Public Accounting Firm

To the Board of Trustees of Pioneer Series Trust VII and Shareowners of Pioneer
Global High Yield Fund:
--------------------------------------------------------------------------------
We have audited the accompanying statement of assets and liabilities, including
the schedule of investments, of Pioneer Global High Yield Fund (one of the
portfolios constituting Pioneer Series Trust VII), as of October 31, 2015, and
the related statement of operations for the year then ended and the statements
of changes in net assets and the financial highlights for each of the two years
in the period then ended. These financial statements and financial highlights
are the responsibility of the Fund's management. Our responsibility is to
express an opinion on these financial statements and financial highlights based
on our audits. The financial highlights for the years ended October 31, 2013,
2012, and 2011 were audited by other auditors. Those auditors expressed an
unqualified opinion on those financial statements and financial highlights in
their report dated December 23, 2013.

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. The Fund
is not required to have, nor were we engaged to perform, an audit of its
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, assessing the accounting principles
used and significant estimates made by management, as well as evaluating the
overall financial statement presentation. Our procedures included confirmation
of securities owned as of October 31, 2015, by correspondence with the custodian
and brokers; where replies were not received from brokers, we performed other
auditing procedures. We believe that our audits provide a reasonable basis for
our opinion.

In our opinion, the financial statements and financial highlights
referred to above present fairly, in all material respects, the financial
position of Pioneer Global High Yield Fund as of October 31, 2015, the results
of its operations for the year then ended, and the changes in its net assets and
the financial highlights for each of the two years in the period then ended, in
conformity with accounting principles generally accepted in the United States of
America.

Additional Information (unaudited)

Pioneer Investment Management, Inc. (the "Adviser"), each fund's investment
adviser, is currently an indirect, wholly owned subsidiary of UniCredit S.p.A.
("UniCredit"). On November 11, 2015, UniCredit announced that it signed a
binding master agreement with Banco Santander and affiliates of Warburg Pincus
and General Atlantic (the "Private Equity Firms") with respect to Pioneer
Investments ("Pioneer") and Santander Asset Management ("SAM") (the
"Transaction").

The Transaction, as previously announced by UniCredit, will establish a holding
company, with the name Pioneer Investments, to be owned by UniCredit (50%) and
the Private Equity Firms (50% between them). The holding company will control
Pioneer's U.S. operations, including PIM. The holding company also will own
66.7% of Pioneer's and SAM's combined operations outside the U.S., while Banco
Santander will own directly the remaining 33.3% stake. The closing of the
Transaction is expected to happen in 2016, subject to certain regulatory and
other approvals.

Under the Investment Company Act of 1940, completion of the Transaction will
cause each fund's current investment advisory agreement with PIM to terminate.
Accordingly, each fund's Board of Trustees will be asked to approve a new
investment advisory agreement. If approved by the Board, each fund's new
investment advisory agreement will be submitted to the shareholders of the fund
for their approval.

Qualified interest income is exempt from nonresident alien (NRA) tax
withholding. The percentage of the Fund's ordinary income distributions derived
from qualified interest income was 65.9%.

Subsequent Events (unaudited)

Effective November 2, 2015, Boston Financial Data Service became the transfer
agent to the Fund at negotiated rates.

Approval of Investment Advisory Agreement

Pioneer Investment Management, Inc. (PIM) serves as the investment adviser to
Pioneer Global High Yield Fund (the Fund) pursuant to an investment advisory
agreement between PIM and the Fund. In order for PIM to remain the investment
adviser of the Fund, the Trustees of the Fund must determine annually whether to
renew the investment advisory agreement for the Fund.

The contract review process began in January 2015 as the Trustees of the Fund
agreed on, among other things, an overall approach and timeline for the process.
Contract review materials were provided to the Trustees in March 2015 and July
2015. Supplemental contract review materials were provided to the Trustees in
September 2015. In addition, the Trustees reviewed and discussed the Fund's
performance at regularly scheduled meetings throughout the year and took into
account other information related to the Fund provided to the Trustees at
regularly scheduled meetings in connection with the review of the Fund's
investment advisory agreement.

In March 2015, the Trustees, among other things, discussed the memorandum
provided by Fund counsel that summarized the legal standards and other
considerations that are relevant to the Trustees in their deliberations
regarding the renewal of the investment advisory agreement, and reviewed and
discussed the qualifications of the investment management teams, as well as the
level of investment by the Fund's portfolio managers in the Fund. In July 2015,
the Trustees, among other things, reviewed the Fund's management fee and total
expense ratios, the financial statements of PIM and its parent companies, the
profitability analyses provided by PIM, and possible economies of scale. The
Trustees also reviewed the profitability of the institutional business of PIM
and PIM's affiliate, Pioneer Institutional Asset Management, Inc. (together with
PIM, "Pioneer"), as compared to that of PIM's fund management business, and
considered the differences between the fees and expenses of the Fund and the
fees and expenses of Pioneer's institutional accounts, as well as the different
services provided by PIM to the Fund and by Pioneer to the institutional
accounts. The Trustees further considered contract review materials in September
2015.

At a meeting held on September 15, 2015, based on their evaluation of the
information provided by PIM and third parties, the Trustees of the Fund,
including the Independent Trustees voting separately, unanimously approved the
renewal of the investment advisory agreement for another year. In approving the
renewal of the investment advisory agreement, the Trustees considered various
factors that they determined were relevant, including the factors described
below. The Trustees did not identify any single factor as the controlling factor
in determining to approve the renewal of the agreement.

                    Pioneer Global High Yield Fund | Annual Report | 10/31/15 67


Nature, Extent and Quality of Services

The Trustees considered the nature, extent and quality of the services that had
been provided by PIM to the Fund, taking into account the investment objective
and strategy of the Fund. The Trustees also reviewed PIM's investment approach
for the Fund and its research process. The Trustees considered the resources of
PIM and the personnel of PIM who provide investment management services to the
Fund. They also reviewed the amount of non-Fund assets managed by the portfolio
managers of the Fund. The Trustees considered the non-investment resources and
personnel of PIM involved in PIM's services to the Fund, including PIM's
compliance and legal resources and personnel. The Trustees noted the substantial
attention and high priority given by PIM's senior management to the Pioneer fund
complex.

The Trustees considered that PIM supervises and monitors the performance of the
Fund's service providers and provides the Fund with personnel (including Fund
officers) and other resources that are necessary for the Fund's business
management and operations. The Trustees also considered that, as administrator,
PIM is responsible for the administration of the Fund's business and other
affairs. The Trustees considered the fees paid to PIM for the provision of
administration services.

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

Performance of the Fund

In considering the Fund's performance, the Trustees regularly review and discuss
throughout the year data prepared by PIM and information comparing the Fund's
performance with the performance of its peer group of funds as classified by
each of Morningstar, Inc. (Morningstar) and Lipper, and with the performance of
the Fund's benchmark index. They discussed the Fund's performance with PIM on a
more frequent basis in light of the Fund's unfavorable performance compared to
its benchmark index and peers over certain periods. The Trustees noted PIM's
explanation for the Fund's relative performance and the steps taken by PIM to
address the Fund's performance, including enhancing the investment process used
for the Fund and reducing the Fund's emerging markets exposure. The Trustees'
reviews and discussions, including the steps taken by PIM to address the Fund's
performance, were factored into the Trustees' deliberations concerning the
renewal of the advisory agreement.

68  Pioneer Global High Yield Fund | Annual Report | 10/31/15


Management Fee and Expenses

The Trustees considered information showing the fees and expenses of the Fund in
comparison to the management fees and expense ratios of its peer group of funds
as classified by Morningstar and also to the expense ratios of a peer group of
funds selected on the basis of criteria determined by the Independent Trustees
for this purpose using data provided by Strategic Insight Mutual Fund Research
and Consulting, LLC (Strategic Insight), an independent third party. In all
quintile rankings referred to below, first quintile is most favorable to the
Fund's shareowners.

The Trustees considered that the Fund's management fee for the most recent
fiscal year was in the third quintile relative to the management fees paid by
other funds in its Morningstar peer group for the comparable period. The
Trustees also considered the breakpoints in the management fee schedule and the
reduced fee rates above certain asset levels. The Trustees considered that the
expense ratio of the Fund's Class A shares for the most recent fiscal year was
in the fourth quintile relative to its Morningstar peer group and in the fourth
quintile relative its Strategic Insight peer group, in each case for the
comparable period. The Trustees considered that the expense ratio of the Fund's
Class Y shares for the most recent fiscal year was in the fourth quintile
relative to its Morningstar peer group and in the fourth quintile relative its
Strategic Insight peer group, in each case for the comparable period. The
Trustees considered the impact of transfer agency, sub-transfer agency and other
non-management fee expenses on the expense ratios of the Fund, and noted the
impact of expenses relating to small accounts and omnibus accounts on transfer
and sub-transfer agency expenses generally. The Trustees noted that they
separately review the Fund's transfer agency, sub-transfer agency and
intermediary arrangements.

The Trustees reviewed management fees charged by Pioneer to institutional and
other clients, including publicly offered European funds sponsored by affiliates
of Pioneer, unaffiliated U.S. registered investment companies (in a sub-advisory
capacity), and unaffiliated foreign and domestic separate accounts. The Trustees
also considered PIM's costs in providing services to the Fund and Pioneer's
costs in providing services to the other clients and considered the differences
in management fees and profit margins for Fund and non-Fund services. In
evaluating the fees associated with Pioneer's client accounts, the Trustees took
into account the respective demands, resources and complexity associated with
the Fund and client accounts. The Trustees noted that, in some instances, the
fee rates for those clients were lower than the management fee for the Fund and
considered that, under the investment advisory agreement with the Fund, PIM
performs additional services for the Fund that it does not provide to those
other clients or services that are broader in scope, including oversight of the
Fund's other service providers and

                    Pioneer Global High Yield Fund | Annual Report | 10/31/15 69


activities related to compliance and the extensive regulatory and tax regimes to
which the Fund is subject. The Trustees also considered the different
entrepreneurial risks associated with PIM's management of the Fund and Pioneer's
management of the other client accounts.

The Trustees concluded that the management fee payable by the Fund to PIM was
reasonable in relation to the nature and quality of the services provided by PIM
to the Fund.

Profitability

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

Economies of Scale

The Trustees considered PIM's views relating to economies of scale in connection
with the Pioneer Funds as fund assets grow and the extent to which any such
economies of scale are shared with funds and fund shareholders. The Trustees
noted the breakpoints in the management fee schedule. The Trustees recognize
that economies of scale are difficult to identify and quantify, and that, among
other factors that may be relevant, are the following: fee levels, expense
subsidization, investment by PIM in research and analytical capabilities and
PIM's commitment and resource allocation to the Fund. The Trustees noted that
profitability also may be an indicator of the availability of any economies of
scale, although profitability may vary for other reasons including due to
reductions in expenses. The Trustees concluded that economies of scale, if any,
were being appropriately shared with the Funds.

Other Benefits

The Trustees considered the other benefits to PIM from its relationship with the
Fund. The Trustees considered the character and amount of fees paid by the Fund,
other than under the investment advisory agreement, for services

70 Pioneer Global High Yield Fund | Annual Report | 10/31/15


provided by PIM and its affiliates. The Trustees further considered the
revenues and profitability of PIM's businesses other than the fund business.
Pioneer is the principal U.S. asset management business of Pioneer Global Asset
Management, the worldwide asset management business of UniCredit Group, which
manages over $150 billion in assets (including the Funds). Pioneer and the Funds
receive reciprocal intangible benefits from the relationship, including mutual
brand recognition and, for the Funds, direct and indirect access to the
resources of a large global asset manager. The Trustees concluded that any such
benefits received by Pioneer as a result of its relationship with the Funds were
reasonable and their consideration of the advisory agreement between the Fund
and PIM and the fees thereunder were unaffected by Pioneer's possible receipt of
any such intangible benefits.

Conclusion

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

President's Letter

Dear Shareholder,

Through the first three quarters of 2015, global markets experienced pockets of
higher-than-average volatility due to significant cross-currents from different
geographic regions. All year, investors focused on the Federal Reserve System's
(the Fed's) deliberations over when to begin normalizing interest rates.
However, while there were signs of gradual economic improvement in the U.S.,
economies abroad increasingly diverged. In June, for example, investors grew
concerned about the debt crisis in Greece. That news, in turn, was followed by
evidence of an economic slowdown in China, which only served to exacerbate
existing worries about growth trends in the emerging markets, a segment of the
global economy already being negatively impacted by slumping commodity prices,
including the price of crude oil, which has been in near-steady decline for
almost a year. Through September 30, 2015, the pockets of heightened market
volatility alluded to above had resulted in the Standard & Poor's 500 Index
turning in a negative (-5.27%) return over the first nine months of the year.
However, the S&P 500 recovered nicely in October, returning 8.43% for the month,
which boosted the index's year-to-date return into positive territory, at 2.71%.

Despite the headwinds still vexing the global economy, our longer-term view of
the U.S. economy has remained positive. Economic conditions in the U.S. have
generally been constructive, based largely on improvements in employment
statistics and an uptick in the housing sector, which has aided the consumer
side of the economy, where household spending has been rising modestly. U.S.
consumers also stand to benefit, potentially, from lower energy prices as the
winter weather approaches. We continue to believe the U.S. economy remains on
a slow, steady growth trend, and that it is unlikely to be disrupted by a slow
pace of interest-rate normalization by the Fed.

Pioneer Investments believes that investors in today's environment can
potentially benefit from the consistent and disciplined investment approach we
have used since our founding in 1928. We focus on identifying value across
global markets using proprietary research, careful risk management, and a
long-term perspective. Our ongoing goal is to produce compelling returns
consistent with the stated objectives of our investment products, and with our
shareowners' expectations. We believe our shareowners can benefit from the
experience and tenure of our investment teams as well as the insights generated
from our extensive research process.

2 Pioneer Global Multisector Income Fund | Annual Report | 10/31/15


As always, and particularly during times of market uncertainty, we encourage you
to work with your financial advisor to develop an overall investment plan that
addresses both your short- and long-term goals, and to implement such a plan in
a disciplined manner.

We greatly appreciate your trust in us in the past and look forward to
continuing to serve you in the future.

Sincerely,

/s/ Lisa M. Jones

Portfolio Management Discussion | 10/31/15

The U.S. dollar acted as a bulwark among world currencies during the 12-month
period ended October 31, 2015, a period marked by shifting investor sentiments
and growing uncertainties in the fixed-income markets. In the following
interview, Charles Melchreit and Paresh Upadhyaya discuss the factors that
affected the performance of Pioneer Global Multisector Income Fund during the
12-month period. Mr. Melchreit, Director of Investment-Grade Management, a
senior vice president and a portfolio manager at Pioneer, and Mr. Upadhyaya, a
senior vice president and portfolio manager at Pioneer, are responsible for the
day-to-day management of the Fund, along with Kenneth J. Taubes, Executive Vice
President, Chief Investment Officer, U.S., and a portfolio manager at Pioneer,
and Andrew Feltus, Director of High Yield and Bank Loans, a senior vice
president and a portfolio manager at Pioneer.

Q    How did the Fund perform during the 12 months ended October 31, 2015?

A    Pioneer Global Multisector Income Fund's Class A shares returned -1.00% at
     net asset value during the 12-month period ended October 31, 2015, while
     the Fund's benchmark, the Barclays Global Aggregate Bond Index (the
     Barclays Index), returned -3.07%. During the same period, the average
     return of the 207 mutual funds in Lipper's Global Income Funds category was
     -2.89%, and the average return of the 368 mutual funds in Morningstar's
     World Bond Funds category was -3.85%.

Q    How would you describe the investment environment during the 12-month
     period ended October 31, 2015?

A    Currencies proved to be the dominant factor influencing both risk and
     opportunity in the global fixed-income markets during the period, as a
     series of events and emerging trends created uncertainties in the minds of
     market participants and encouraged investments in the perceived, relative
     safety of the U.S. dollar.

     Among the developments that caused investors to re-evaluate their tactics
     and strategies were: an apparent weakening of economic growth trends across
     much of the globe, signaled by falling commodity prices in general, and oil
     prices in particular; the devaluation of the Chinese currency (the yuan),
     which marked the first devaluation of that currency in its trading band in
     more than two decades; the re-emergence of the debt crisis in Greece during
     July 2015, which raised speculation about the future of the European Union;
     and anticipation that the U.S. Federal Reserve System (the Fed) - which had
     ended its quantitative easing purchases in late 2014 - would begin to
     further tighten monetary policy by raising short-term interest rates, even
     as other large central banks were loosening their policies.

4 Pioneer Global Multisector Income Fund | Annual Report | 10/31/15


     Concerns about global economy growth escalated in the second quarter of
     2015, as manufacturing activity in China - one of the key economies driving
     global trends - contracted, and there was notable weakness in fixed-
     investment growth. Driven by government policy, the Chinese economy during
     the period continued to undergo a transformation aimed at moving it from a
     production-based to consumption, or consumer-based economy. The contraction
     of manufacturing output raised concerns that the country's economy was
     weaker than had been reported. In response, the Chinese stock market
     plummeted in value from its peak in mid-June, declining by 32% in just one
     month. The sell-off raised concerns that China's economy was becoming
     disorderly, and large divergences developed between the onshore and
     offshore exchange rates for the yuan, which led to the Chinese government's
     August decision to devalue the currency.

     As market worries about China escalated, the prices of oil and other
     commodities started moving lower for the second time in less than a year,
     based on fears that a general economic slowdown would not only affect
     commodity-producing emerging markets economies, but could also hurt
     developed ones, including the U.S. economy.

     Meanwhile, as these trends were developing, the government of Greece
     announced that it would be unable to make its first scheduled repayment of
     an earlier bailout loan from the International Monetary Fund (IMF). In
     addition, a referendum vote by the Greek electorate gave overwhelming
     support to the notion that the Greek government should take a hard line in
     any discussions with the IMF, the European Central Bank (ECB), and the
     European commission -- collectively known as "the Troika." However, the
     Troika signaled that its members might not provide any further assistance
     to Greece without concessions. In the end, as stocks declined in value and
     Greek banks were forced to close their doors, the Greek government
     retreated from its hard-line stance and accepted the Troika's terms. The
     entire crisis, however, increased turmoil in world currency markets,
     leading to further weakening of the euro and euro-linked currencies, and
     further strengthening of the U.S. dollar.

     In the United States, the Fed indicated throughout the period that it could
     begin to hike the influential Federal funds rate, as evidence appeared that
     the domestic economy was strengthening and that the nation's unemployment
     rate was approaching the Fed's target for a non-accelerating inflation rate
     of unemployment (NAIRU) of 4.9% -- a level that generally leads to higher
     wage-inflation rates. (The Fed has kept the Federal funds rate at near zero
     - between 0.00% and 0.25% - since 2009.) However, the rate hike did not
     happen before the end of the 12-month period, as the Fed maintained a
     cautious policy stance, citing global economic instability,

             Pioneer Global Multisector Income Fund | Annual Report | 10/31/15 5


     among other reasons, for delaying a rate increase. Towards the end of the
     period, however, the Fed did send out new signals that a gradual series of
     interest-rate hikes could begin in the near future.

Q    In that environment, how did the Fund's positioning affect performance
     relative to the Barclays Index during the 12-month period ended October 31,
     2015?

A    In a challenging period for investing in global fixed-income markets, the
     Fund's Class A shares generated slightly negative results. Nevertheless,
     the Fund solidly outperformed its benchmark, the Barclays Index, and its
     peer groups during the period. Driving the Fund's benchmark-relative
     outperformance during the period was our overweighting of the U.S. dollar,
     an underweight in major foreign currencies, and short portfolio positions
     held in those same foreign currencies -- notably, the euro and the Japanese
     yen. Less consequential, but also a factor contributing to the Fund's
     relative outperformance, was short positioning in some emerging markets
     currencies.

     The positive effects of the Fund's emphasis on the U.S. dollar more than
     offset some factors that detracted, somewhat, from relative returns,
     including the portfolio's short-duration stance in Europe, where interest
     rates declined. (Duration is a measure of the sensitivity of the price, or
     the value of principal, of a fixed-income investment to a change in
     interest rates, expressed as a number of years). In addition, the Fund's
     overweighting of the sovereign debt of some emerging markets nations and
     underweight positions in both U.S. Treasuries and European sovereign bonds
     detracted from benchmark-relative performance, but not enough to offset the
     positive effects of the portfolio's overall currency positioning.

     We maintained a short-duration stance in the Fund's portfolio throughout
     the 12-month period, but the potentially negative effects of that
     positioning were more than compensated for by the positive benefits of the
     aforementioned currency positioning.

Q    What were the principal factors affecting the Fund's yield during the
     12-month period ended October 31, 2015?

A    Interest rates throughout the globe tended to decline during the 12 months.
     Consequently, the Fund's dividend* yield also declined as new investments -
     with lower coupon rates - provided less current income than older portfolio
     investments that had either reached maturity, or were sold.

*    Dividends are not guaranteed.

6 Pioneer Global Multisector Income Fund | Annual Report | 10/31/15


Q    Did the Fund invest in any derivative securities during the 12-month period
     ended October 31, 2015? If so, did those investments affect the Fund's
     performance?

A    Yes, we did invest the Fund in forward currency transactions as part of our
     strategy to emphasize the U.S. dollar relative to other world currencies.
     The strategy, which included the use of the derivative securities, provided
     significant help and contributed to the Fund's outperformance of its
     benchmark. Conversely, a short portfolio position in U.S. Treasury futures
     had a slight negative influence on the Fund's performance. In addition, the
     Fund had a small position in credit default swaps early in the period,
     which we employed in an attempt to hedge the portfolio's exposure to
     high-yield securities. The credit default swaps had no material effect on
     the Fund's results.

Q    What is your investment outlook?

A    We remain bullish on the U.S. dollar, especially if the monetary policies
     of the world's central banks start diverging even further, with the Fed
     perhaps moving to tighten policy and raise rates at the same time other
     banks, such as the ECB, continue to ease their policies to facilitate
     economic growth and reduce deflationary risks in their respective countries
     or regions. In the absence of any unanticipated increase in inflation or
     decline in economic growth rates, we expect that the Fed will begin a
     gradual tightening process by raising interest over a series of steps.

     With regard to the Fund, we expect to maintain our current strategy that
     emphasizes the U.S. dollar in the portfolio's currency positioning. At the
     same time, we anticipate keeping a short-duration stance in the portfolio,
     given our previously stated belief that the Fed will soon begin to raise
     short-term interest rates.

Please refer to the Schedule of Investments on pages 17-36 for a full listing of
Fund securities.

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

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 price volatility, illiquidity and possibility of default.

Prepayment risk is the chance that an issuer may exercise its right to prepay
its security, if falling interest rates prompt the issuer to do so. 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.

The Fund 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 securities issued by U.S. Government-sponsored entities (e.g., FNMA, Freddie
Mac) are neither guaranteed nor issued by the U.S. Government.

Floating rate loans and similar instruments may be illiquid or less liquid than
other instruments, and the value of any collateral can decline or be
insufficient to meet the issuer's obligations.

The value of municipal securities can be adversely affected by changes in
financial condition of municipal issuers, lower revenues, and regulatory and
political developments.

The Fund is subject to currency risk, meaning that the Fund could experience
losses based on changes in the exchange rate between non-U.S. currencies and the
U.S. dollar.

The Fund may use derivatives, such as options, futures, inverse floating rate
obligations, swaps, and others, which can be illiquid, may disproportionately
increase losses, and have a potentially large impact on Fund performance.
Derivatives may have a leveraging effect on the Fund.

These risks may increase share price volatility.

and expenses. Contact your advisor or Pioneer Investments for a prospectus or
summary prospectus containing this information. Read it carefully.

Index Definitions
--------------------------------------------------------------------------------
The Barclays Global Aggregate Bond Index is an unmanaged index that provides a
broad-based measure of the global investment-grade fixed-income markets. 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 index defined here pertains to the "Value of $10,000 Investment" and "Value
of $5 Million Investment" charts appearing on pages 12-14.

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 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 the contractual expense limitation currently in
effect through March 1, 2016, for Class A shares. There can be no assurance that
Pioneer will extend the expense limitation beyond such time. Please see the
prospectus and financial statements for more information.

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

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 Y shares are not subject to sales charges and are available for limited
groups of eligible investors, including institutional investors. All results are
historical and assume the reinvestment of dividends and capital gains. Other
share classes are available for which performance and expenses will differ.

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

The net expense ratio reflects the contractual expense limitation currently in
effect through March 1, 2016, for Class Y shares. There can be no assurance that
Pioneer will extend the expense limitation beyond such time. Please see the
prospectus and financial statements for more information.

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

Comparing Ongoing Fund Expenses

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

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

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

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

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

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

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

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

*    Expenses are equal to the Fund's annualized expense ratio of 1.00%, 1.90%,
     and 0.75% for Class A, Class C and Class Y shares, respectively, multiplied
     by the average account value over the period, multiplied by 184/365 (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 | 10/31/15

1. Organization and Significant Accounting Policies

Pioneer Global Multisector Income 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 a high level of
current income.

The Fund offers three classes of shares designated as Class A, Class C, and
Class Y shares. 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 of Trustees 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:

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 are valued at prices supplied by independent pricing
     services, which consider such factors as market prices, market events,
     quotations from

44 Pioneer Global Multisector Income Fund | Annual Report | 10/31/15


     one or more brokers, Treasury spreads, yields, maturities and ratings.
     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.
     If price information is not available from Loan Pricing Corporation, or if
     the price information is deemed to be unreliable, price information will be
     obtained from an alternative loan interest pricing service. If no reliable
     price quotes are available from either the primary or alternative pricing
     service, broker quotes will be solicited. Event-linked bonds are valued at
     the bid price obtained from an independent third party pricing service.
     Other insurance-linked securities may be valued at the bid price obtained
     from an independent pricing service, or through a third party using a
     pricing matrix, insurance industry valuation models, or other fair value
     methods or techniques to provide an estimated value of the instrument.
     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. Cash may include overnight time
     deposits at approved financial institutions.

     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 market prices and/or quotations are
     not readily available or are considered to be unreliable are valued by a
     fair valuation team comprised of certain personnel of Pioneer Investment
     Management, Inc. (PIM), the Fund's investment adviser, pursuant to
     procedures adopted by the Fund's Board of Trustees. PIM's fair valuation
     team uses fair value methods approved by the Valuation Committee of the
     Board of Trustees. PIM's fair valuation team is responsible for monitoring
     developments that may impact fair valued securities and for discussing and
     assessing fair values on an ongoing basis, and at least quarterly, with the
     Valuation Committee of the Board of Trustees.

     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. 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

            Pioneer Global Multisector Income Fund | Annual Report | 10/31/15 45


     disasters, terrorist activity or trading halts. Thus, the valuation of the
     Fund's securities may differ significantly from exchange prices and such
     differences could be material.

     At October 31, 2015, there were no securities that were valued using fair
     value methods (other than securities valued using prices supplied by
     independent pricing services or broker-dealers or through a third party
     using an insurance industry valuation model).

B.   Investment Income and Transactions

     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 purchase prices of 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. 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.

C.   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 the market prices of those securities but are
     included with the net realized and unrealized gain or loss on investments.

46 Pioneer Global Multisector Income Fund | Annual Report | 10/31/15


D.   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 appreciation or depreciation
     is recorded in the Fund's financial statements. The Fund records realized
     gains and losses at the time a contract 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).

E.   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 net taxable income and net realized capital gains, if any, to
     its shareowners. Therefore, no provision for federal income taxes is
     required. As of October 31, 2015, the Fund did not accrue any interest or
     penalties with respect to uncertain tax positions, which, if applicable,
     would be recorded as an income tax expense in the Statement of Operations.
     Tax returns filed within the prior three years remain subject to
     examination by federal and state tax authorities.

     The amount and character of income and capital gain distributions to
     shareowners are determined in accordance with federal income tax rules,
     which may differ from U.S. generally accepted accounting principles.
     Distributions in excess of net investment income or net realized gains are
     temporary overdistributions for financial statement purposes resulting from
     differences in the recognition or classification of income or distributions
     for financial statement and tax purposes. Capital accounts within the
     financial statements are adjusted for permanent book/tax differences to
     reflect tax character, but are not adjusted for temporary differences. At
     October 31, 2015, the Fund reclassified $444,774 to increase undistributed
     net investment income and $444,774 to increase accumulated net realized
     loss on investments futures contracts, swap contracts, written options, and
     foreign currency transactions to reflect permanent book/tax differences.
     These adjustments have no impact on net assets or the results of
     operations.

     At October 31, 2015, the Fund was permitted to carry forward indefinitely
     $64,518 of long-term losses under the Regulated Investment Company
     Modernization Act of 2010 without limitation.

     The tax character of distributions paid during the years ended October 31,
     2015, and October 31, 2014, were as follows:



     ---------------------------------------------------------------------------
                                                             2015           2014
     ---------------------------------------------------------------------------
                                                                  
     Distributions paid from:
     Ordinary income                                   $  856,632       $835,366
     Long-term capital gain                               238,626        159,919
     ---------------------------------------------------------------------------
         Total                                         $1,095,258       $995,285
     ===========================================================================


     The following shows the components of distributable earnings on a federal
     income tax basis at October 31, 2015:



     ---------------------------------------------------------------------------
                                                                           2015
     ---------------------------------------------------------------------------
                                                                 
     Distributable earnings:
     Undistributed ordinary income                                  $   199,660
     Capital loss carryforward                                          (64,518)
     Current year dividend payable                                      (42,347)
     Unrealized depreciation                                         (1,097,662)
     ---------------------------------------------------------------------------
         Total                                                      $(1,004,867)
     ===========================================================================


     The difference between book-basis and tax-basis net unrealized depreciation
     is attributable to the tax deferral of losses on wash sales, adjustments
     related to sidecars, the mark-to-market of forward and futures contracts,
     and interest accruals on preferred stock.

F.   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 $1,700 in underwriting commissions on the sale of Class
     A shares during the year ended October 31, 2015.

G.   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 Fund's transfer agent, 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).

48 Pioneer Global Multisector Income Fund | Annual Report | 10/31/15


     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.

H.   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.

     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.

I.   Insurance Linked Securities (ILS)

     The Fund invests in event-linked bonds. Event-linked bonds are floating
     rate debt obligations for which the return of principal and the payment of
     interest are contingent on the non-occurrence of a pre-defined "trigger"
     event, such as a hurricane or an earthquake of a specific magnitude. The
     trigger event's magnitude may be based on losses to a company or industry,
     industry indexes or readings of scientific instruments, or may be based on
     specified actual losses. If a trigger event, as defined within the terms of
     an event-linked bond occurs, the Fund may lose a portion or all of its
     accrued interest and/or principal invested in such event-linked bond. The
     Fund is entitled to receive principal and interest payments so long as no
     trigger event occurs of the description and magnitude specified by the
     instrument. In addition to the

            Pioneer Global Multisector Income Fund | Annual Report | 10/31/15 49


     specified trigger events, event-linked bonds may expose the Fund to other
     risks, including but not limited to issuer (credit) default, adverse
     regulatory or jurisdictional interpretations and adverse tax consequences.

     The Fund's investments in ILS may include special purpose vehicles ("SPVs")
     or similar instruments structured to comprise a portion of a reinsurer's
     catastrophe-oriented business, known as quota share instruments (sometimes
     referred to as reinsurance sidecars), or to provide reinsurance relating to
     specific risks to insurance or reinsurance companies through a
     collateralized instrument, known as collateralized reinsurance. Structured
     reinsurance investments, which also may include industry loss warranties
     ("ILWs"), are subject to the same risks as event-linked bonds. In addition,
     because quota share instruments represent an interest in a basket of
     underlying reinsurance contracts, the Fund has limited transparency into
     the individual underlying contracts and therefore must rely upon the risk
     assessment and sound underwriting practices of the issuer. Accordingly, it
     may be more difficult for PIM to fully evaluate the underlying risk profile
     of the Fund's investment in quota share instruments and therefore place the
     Fund's assets at greater risk of loss than if PIM had more complete
     information.

     Quota share instruments and other structured reinsurance instruments
     generally will be considered illiquid securities by the Fund. These
     securities may be difficult to purchase, sell or unwind. Illiquid
     securities also may be difficult to value. If the Fund is forced to sell an
     illiquid asset, the Fund may be forced to sell at a loss.

J.   Futures Contracts

     The Fund may enter into futures transactions in order to attempt 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. The amount of cash deposited with the broker as collateral at
     October 31, 2015 was $71,550. 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 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. With futures, there is minimal counterparty
     credit risk to the Fund since futures are exchange-traded and

50 Pioneer Global Multisector Income Fund | Annual Report | 10/31/15


     the exchange's clearinghouse, as counterparty to all exchange-traded
     futures, guarantees the futures against default. The average value of
     contracts open during the year ended October 31, 2015, was $(3,154,682).

     At October 31, 2015, open futures contracts were as follows:



     -----------------------------------------------------------------------------------------
                                                                                Net

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


K.   Repurchase Agreements

     Repurchase agreements are arrangements under which the Fund purchases
     securities from a broker-dealer or a bank, called the counterparty, upon
     the agreement of the counterparty to repurchase the securities from the
     Fund at a later date, and at a specific price, which is typically higher
     than the purchase price paid by the Fund. The securities purchased serve as
     the Fund's collateral for the obligation of the counterparty to repurchase
     the securities. The value of the 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, PIM is responsible for determining
     that the value of the collateral remains at least equal to the repurchase
     price. In the event of a default by the counterparty, the Fund is entitled
     to sell the securities, but the Fund may not be able to sell them for the
     price at which they were purchased, thus causing a loss to the Fund.
     Additionally, if the counterparty becomes insolvent, there is some risk
     that the Fund will not have a right to the securities, or the immediate
     right to sell the securities. As of the year ended October 31, 2015, the
     Fund had no open repurchase agreements.

L.   Option Writing

     The Fund may write put and covered call options to seek to increase total
     return. When an option is written, the Fund receives a premium and becomes
     obligated to purchase or sell the underlying security at a fixed price,
     upon the exercise of the option. When the Fund writes an option, an amount
     equal to the premium received by the Fund is recorded as a liability and is
     subsequently adjusted to the current value of the option written. Premiums
     received from writing options that expire unexercised are treated by the
     Fund on the expiration date as realized gains from investments. The
     difference

            Pioneer Global Multisector Income Fund | Annual Report | 10/31/15 51


     between the premium and the amount paid on effecting a closing purchase
     transaction, including brokerage commissions, is also treated as a realized
     gain, or, if the premium is less than the amount paid for the closing
     purchase transaction, as a realized loss. If a call option is exercised,
     the premium is added to the proceeds from the sale of the underlying
     security in determining whether the Fund has realized a gain or loss. The
     Fund as writer of an option bears the market risk of an unfavorable change
     in the price of the security underlying the written option.

     The average value of written options contracts open during the year ended
     October 31, 2015, was $0.

     There were no written options outstanding as of October 31, 2015.

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


M.   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 sell
     or buy credit default swap contracts to seek to increase the Fund's income,
     or to attempt to hedge the risk of default on portfolio securities. A
     credit default swap index is used to hedge risk or take a position on a
     basket of credit entities or indices. 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.

     When the Fund enters into a credit default swap contract, 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

52 Pioneer Global Multisector Income Fund | Annual Report | 10/31/15


     made by the Fund, as the protection buyer, is recorded as an asset in the
     Statement of Assets and Liabilities. Periodic payments received or paid by
     the Fund are recorded as realized gains or losses in the Statement of
     Operations.

     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 appreciation or depreciation in the Statement of
     Assets and Liabilities. 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 in
     the Statement of Operations.

     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.

     Certain swap contracts that are cleared through a central clearinghouse are
     referred to as centrally cleared swaps. All payments made or received by
     the Fund are pursuant to a centrally cleared swap contract with the central
     clearing party rather than the original counterparty. Upon entering into a
     centrally cleared swap contract, the Fund is required to make an initial
     margin deposit, either in cash or in securities. The daily change in value
     on open centrally cleared contracts is recorded as variation margin on
     centrally cleared swaps on the Statement of Assets and Liabilities.

     Open credit default swap contracts at October 31, 2015, are listed in the
     Schedule of Investments. The average value of swap contracts open during
     the year ended October 31, 2015 was $14,698.

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, 2015, are reflected on the Statement of Operations. These expense

            Pioneer Global Multisector Income Fund | Annual Report | 10/31/15 53


limitations are in effect through March 1, 2017. There can be no assurance that
PIM will extend the expense limitation agreement for a class of shares beyond
the date referred to above.

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 from affiliates" reflected on the Statement of Assets and Liabilities is
$13,184 in management fees, administrative costs and certain other
reimbursements due to PIM at October 31, 2015.

3. Transfer Agent

Pioneer Investment Management Shareholder Services, Inc. (PIMSS), a wholly owned
indirect subsidiary of UniCredit, provided substantially all transfer agent and
shareowner services to the Fund at negotiated rates.

In addition, the Fund reimbursed 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, 2015, such out-of-pocket expenses by class of shares
were as follows:

Class A                                                                 $118,880

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


Included in "Due to affiliates" reflected on the Statement of Assets and
Liabilities is $38,940 in transfer agent fees and out-of-pocket reimbursements
payable to PIMSS at October 31, 2015.

4. 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 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

54 Pioneer Global Multisector Income Fund | Annual Report | 10/31/15


distribution services with regard to Class C shares. Included in "Due to
affiliates" reflected on the Statement of Assets and Liabilities is $598 in
distribution fees payable to PFD at October 31, 2015.

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 12 months 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 shares. Proceeds from the CDSCs are paid to PFD. For the
year ended October 31, 2015, CDSCs in the amount of $784 were paid to PFD.

5. Expense Offset Arrangements

The Fund 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, 2015, the Fund's expenses
were not reduced under such arrangements.

6. Forward Foreign Currency Contracts

At October 31, 2015, 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 forward foreign
currency contracts open during the year ended October 31, 2015, was
$(6,657,098).

            Pioneer Global Multisector Income Fund | Annual Report | 10/31/15 55

7. Assets and Liabilities Offsetting

The Fund has entered into an International Swaps and Derivatives Association,
Inc. Master Agreement ("ISDA Master Agreement") or similar agreement with
substantially all its derivative counterparties. An ISDA Master Agreement is a
bilateral agreement between the Fund and a counterparty that governs the trading
of certain OTC derivatives and typically contains, among other things, close-out
and set-off provisions which apply upon the occurrence of event of a default
and/or termination event as defined under the relevant ISDA Master Agreement.
The ISDA Master Agreement may also give a party the right to terminate all
transactions traded under such agreement if, among other things, there is
deterioration in the credit quality of the other party. Upon an event of

56 Pioneer Global Multisector Income Fund | Annual Report | 10/31/15


default or a termination of the ISDA Master Agreement, the non-defaulting party
has the right to close out all transactions under such agreement and to net
amounts owed under each transaction to determine one net amount payable by one
party to the other. The right to close out and net payments across all
transactions under the ISDA Master Agreement could result in a reduction of the
Fund's credit risk to its counterparty equal to any amounts payable by the Fund
under the applicable transactions, if any. However, the Fund's right to setoff
may be restricted or prohibited by the bankruptcy or insolvency laws of the
particular jurisdiction to which a specific ISDA counterparty is subject.

The collateral requirements for derivatives transactions under an ISDA Master
Agreement are governed by a credit support annex to the ISDA Master Agreement.
Collateral requirements are generally determined at the close of business each
day and are typically based on changes in market values for each transaction
under an ISDA Master Agreement and netted into one amount for such agreement.
Generally, the amount of collateral due from or to a counterparty is subject to
threshold (a "minimum transfer amount") before a transfer is required, which may
vary by counterparty. Collateral pledged for the benefit of the Fund and/or
counterparty is held in segregated accounts by the Fund's custodian and cannot
be sold, re-pledged, assigned or otherwise used while pledged. Cash that has
been segregated to cover the Fund's collateral obligations, if any, will be
reported separately in the Statement of Assets and Liabilities as "Futures
collateral", "Swap Collateral" or "Deposit with broker." Securities pledged by
the Fund as collateral, if any, are identified as such in the Schedule of
Investments.

Financial instruments subject to an enforceable master netting agreement such as
an ISDA Master Agreement have been offset on the Statement of Assets and
Liabilities. The following charts show gross assets and liabilities of the Fund
as of October 31, 2015.

8. Additional Disclosures about Derivative Instruments and Hedging Activities

The Fund's use of derivatives subjects it to the following risks:

Interest rate risk relates to the fluctuations in the value of interest-bearing
securities due to changes in the prevailing levels of market interest rates.

Credit risk relates to the ability of the issuer of a financial instrument to
make further principal or interest payments on an obligation or commitment that
it has to the Fund.

Foreign exchange rate risk relates to fluctuations in the value of an asset or
liability due to changes in currency exchange rates.

Equity risk relates to the fluctuations in the value of financial instruments as
a result of changes in market prices (other than those arising from interest
rate risk or foreign exchange risk), whether caused by factors specific to an
individual investment, its issuer, or all factors affecting all instruments
traded in a market or market segment.

Commodity risk relates to the risk that the value of a commodity or commodity
index will fluctuate based on increases or decreases in the commodities market
and factors specific to a particular industry or commodity.

10. 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 June 9, 2015, was in the amount of $215 million.
As of June 9, 2015, the facility is in the amount of $240 million. Under such
facility, depending on the type of loan, interest on borrowings is payable at
the London Interbank Offered Rate (LIBOR) plus 0.85% 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
Eurodollar 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, 2015, the Fund had no borrowings under
the credit facility.

are the responsibility of the Fund's management. Our responsibility is to
express an opinion on these financial statements and financial highlights based
on our audits. The financial highlights for the years ended October 31, 2013,
2012, and 2011 were audited by other auditors. Those auditors expressed an
unqualified opinion on those financial statements and financial highlights in
their report dated December 23, 2013.

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. The Fund
is not required to have, nor were we engaged to perform, an audit of its
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, assessing the accounting principles
used and significant estimates made by management, as well as evaluating the
overall financial statement presentation. Our procedures included confirmation
of securities owned as of October 31, 2015, by correspondence with the custodian
and brokers; where replies were not received from brokers, we performed other
auditing procedures. 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 Multisector Income Fund as of October 31, 2015, and the results
of its operations for the year then ended, and the changes in its net assets and
the financial highlights for each of the two years in the period then ended, in
conformity with accounting principles generally accepted in the United States of
America.

Additional Information

Qualified interest income is exempt from nonresident alien (NRA) tax
withholding. The percentage of the Fund's ordinary income distributions derived
from qualified interest income was 41.27%.

PIM, the Fund's investment adviser, is currently an indirect, wholly owned
subsidiary of UniCredit. On November 11, 2015, UniCredit announced that it
signed a binding master agreement with Banco Santander and affiliates of Warburg
Pincus and General Atlantic (the "Private Equity Firms") with respect to Pioneer
Investments ("Pioneer") and Santander Asset Management ("SAM") (the
"Transaction").

The Transaction, as previously announced by UniCredit, will establish a holding
company, with the name Pioneer Investments, to be owned by UniCredit (50%) and
the Private Equity Firms (50% between them). The holding company will control
Pioneer's U.S. operations, including the Adviser. The holding company also will
own 66.7% of Pioneer's and SAM's combined operations outside the U.S., while
Banco Santander will own directly the remaining 33.3% stake. The closing of the
Transaction is expected to happen in 2016, subject to certain regulatory and
other approvals.

Under the Investment Company Act of 1940, completion of the Transaction will
cause the Fund's current investment advisory agreement with PIM to terminate.
Accordingly, the Fund's Board of Trustees will be asked to approve a new
investment advisory agreement. If approved by the Board, the Fund's new
investment advisory agreement will be submitted to the shareholders of the Fund
for their approval.

Subsequent Event (unaudited)

Effective November 2, 2015, Boston Financials Data Service became the transfer
agent to the Fund at negotiated rates.

Approval of Investment Advisory Agreement

Pioneer Investment Management, Inc. (PIM) serves as the investment adviser to
Pioneer Global Multisector Income Fund (the Fund) pursuant to an investment
advisory agreement between PIM and the Fund. In order for PIM to remain the
investment adviser of the Fund, the Trustees of the Fund must determine annually
whether to renew the investment advisory agreement for the Fund.

The contract review process began in January 2015 as the Trustees of the Fund
agreed on, among other things, an overall approach and timeline for the process.
Contract review materials were provided to the Trustees in March 2015 and July
2015. Supplemental contract review materials were provided to the Trustees in
September 2015. In addition, the Trustees reviewed and discussed the Fund's
performance at regularly scheduled meetings throughout the year and took into
account other information related to the Fund provided to the Trustees at
regularly scheduled meetings in connection with the review of the Fund's
investment advisory agreement.

In March 2015, the Trustees, among other things, discussed the memorandum
provided by Fund counsel that summarized the legal standards and other
considerations that are relevant to the Trustees in their deliberations
regarding the renewal of the investment advisory agreement, and reviewed and
discussed the qualifications of the investment management teams, as well as the
level of investment by the Fund's portfolio managers in the Fund. In July 2015,
the Trustees, among other things, reviewed the Fund's management fee and total
expense ratios, the financial statements of PIM and its parent companies, the
profitability analyses provided by PIM, and possible economies of scale. The
Trustees also reviewed the profitability of the institutional business of PIM
and PIM's affiliate, Pioneer Institutional Asset Management, Inc. (together with
PIM, "Pioneer"), as compared to that of PIM's fund management business, and
considered the differences between the fees and expenses of the Fund and the
fees and expenses of Pioneer's institutional accounts, as well as the different
services provided by PIM to the Fund and by Pioneer to the institutional
accounts. The Trustees further considered contract review materials in September
2015.

At a meeting held on September 15, 2015, based on their evaluation of the
information provided by PIM and third parties, the Trustees of the Fund,
including the Independent Trustees voting separately, unanimously approved the
renewal of the investment advisory agreement for another year. In approving the
renewal of the investment advisory agreement, the Trustees

            Pioneer Global Multisector Income Fund | Annual Report | 10/31/15 63


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

Nature, Extent and Quality of Services

The Trustees considered the nature, extent and quality of the services that had
been provided by PIM to the Fund, taking into account the investment objective
and strategy of the Fund. The Trustees also reviewed PIM's investment approach
for the Fund and its research process. The Trustees considered the resources of
PIM and the personnel of PIM who provide investment management services to the
Fund. They also reviewed the amount of non-Fund assets managed by the portfolio
managers of the Fund. The Trustees considered the non-investment resources and
personnel of PIM involved in PIM's services to the Fund, including PIM's
compliance and legal resources and personnel. The Trustees noted the substantial
attention and high priority given by PIM's senior management to the Pioneer fund
complex.

The Trustees considered that PIM supervises and monitors the performance of the
Fund's service providers and provides the Fund with personnel (including Fund
officers) and other resources that are necessary for the Fund's business
management and operations. The Trustees also considered that, as administrator,
PIM is responsible for the administration of the Fund's business and other
affairs. The Trustees considered the fees paid to PIM for the provision of
administration services.

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

Performance of the Fund

In considering the Fund's performance, the Trustees regularly review and discuss
throughout the year data prepared by PIM and information comparing the Fund's
performance with the performance of its peer group of funds as classified by
each of Morningstar, Inc. (Morningstar) and Lipper, and with the performance of
the Fund's benchmark index. They also discuss the Fund's performance with PIM on
a regular basis. The Trustees' regular reviews and discussions were factored
into the Trustees' deliberations concerning the renewal of the advisory
agreement.

64 Pioneer Global Multisector Income Fund | Annual Report | 10/31/15


Management Fee and Expenses

The Trustees considered information showing the fees and expenses of the Fund in
comparison to the management fees and expense ratios of its peer group of funds
as classified by Morningstar and also to the expense ratios of a peer group of
funds selected on the basis of criteria determined by the Independent Trustees
for this purpose using data provided by Strategic Insight Mutual Fund Research
and Consulting, LLC (Strategic Insight), an independent third party. In all
quintile rankings referred to below, first quintile is most favorable to the
Fund's shareowners.

The Trustees considered that the Fund's management fee for the most recent
fiscal year was in the third quintile relative to the management fees paid by
other funds in its Morningstar peer group for the comparable period. The
Trustees considered that the expense ratio of the Fund's Class A shares for the
most recent fiscal year was in the third quintile relative to its Morningstar
peer group and in the first quintile relative its Strategic Insight peer group,
in each case for the comparable period. The Trustees noted that PIM was waiving
fees and/or reimbursing expenses in order to limit the ordinary operating
expenses of the Fund. The Trustees considered the impact of transfer agency,
sub-transfer agency, and other non-management fee expenses on the expense
ratios of the Fund. The Trustees noted that they separately review the Fund's
transfer agency, sub-transfer agency and intermediary arrangements.

The Trustees reviewed management fees charged by Pioneer to institutional and
other clients, including publicly offered European funds sponsored by affiliates
of Pioneer, unaffiliated U.S. registered investment companies (in a sub-advisory
capacity), and unaffiliated foreign and domestic separate accounts. The Trustees
also considered PIM's costs in providing services to the Fund and Pioneer's
costs in providing services to the other clients and considered the differences
in management fees and profit margins for Fund and non-Fund services. In
evaluating the fees associated with Pioneer's client accounts, the Trustees took
into account the respective demands, resources and complexity associated with
the Fund and client accounts. The Trustees noted that, in some instances, the
fee rates for those clients were lower than the management fee for the Fund and
considered that, under the investment advisory agreement with the Fund, PIM
performs additional services for the Fund that it does not provide to those
other clients or services that are broader in scope, including oversight of the
Fund's other service providers and activities related to compliance and the
extensive regulatory and tax regimes to which the Fund is subject. The Trustees
also considered the different entrepreneurial risks associated with PIM's
management of the Fund and Pioneer's management of the other client accounts.

            Pioneer Global Multisector Income Fund | Annual Report | 10/31/15 65


The Trustees concluded that the management fee payable by the Fund to PIM was
reasonable in relation to the nature and quality of the services provided by PIM
to the Fund.

Profitability

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

Economies of Scale

The Trustees considered PIM's views relating to economies of scale in connection
with the Pioneer Funds as fund assets grow and the extent to which any such
economies of scale are shared with funds and fund shareholders. The Trustees
recognize that economies of scale are difficult to identify and quantify, and
that, among other factors that may be relevant, are the following: fee levels,
expense subsidization, investment by PIM in research and analytical capabilities
and PIM's commitment and resource allocation to the Fund. The Trustees noted
that profitability also may be an indicator of the availability of any economies
of scale, although profitability may vary for other reasons including reductions
in expenses. The Trustees concluded that economies of scale, if any, were being
appropriately shared with the Funds.

Other Benefits

The Trustees considered the other benefits to PIM from its relationship with the
Fund. The Trustees considered the character and amount of fees paid by the Fund,
other than under the investment advisory agreement, for services provided by PIM
and its affiliates. The Trustees further considered the revenues and
profitability of PIM's businesses other than the fund business. Pioneer is the
principal U.S. asset management business of Pioneer Global Asset Management, the
worldwide asset management business of UniCredit Group, which manages over $150
billion in assets (including the Funds). Pioneer and the Funds receive
reciprocal intangible benefits from the relationship, including mutual brand
recognition and, for the Funds, direct

66 Pioneer Global Multisector Income Fund | Annual Report | 10/31/15


and indirect access to the resources of a large global asset manager. The
Trustees concluded that any such benefits received by Pioneer as a result of its
relationship with the Funds were reasonable and their consideration of the
advisory agreement between the Fund and PIM and the fees thereunder were
unaffected by Pioneer's possible receipt of any such intangible benefits.

Conclusion

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

 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.

  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.

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

Beginning with non-audit service contracts entered
into on or after May 6, 2003, the effective date of the
new SEC pre-approval rules, the Trust's audit
committee is required to pre-approve services to
affiliates defined by SEC rules to the extent that the
services are determined to have a direct impact on the
operations or financial reporting of the Trust.  For the
years ended October 31, 2015 and 2014, there were no
services provided to an affiliate that required the
Trust's audit committee pre-approval.



(f) If greater than 50 percent, disclose the percentage of hours expended on the

with the adviser that provides ongoing services to the registrant for each of
the last two fiscal years of the registrant.

The aggregate non-audit fees for the Trust were $17,500

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.

paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X is
compatible with maintaining the principal accountant's
independence.

ITEM 5. AUDIT COMMITTEE OF LISTED REGISTRANTS

(a) If the registrant is a listed issuer as defined in Rule 10A-3
under the Exchange Act (17 CFR 240.10A-3), state whether
