President's Letter

Dear Shareowner,

As we move into the final few months of 2014, we remain confident that U.S.
economic growth remains sustainable, if moderately paced. The weather-related
slowdown in the first quarter is behind us and labor market data continues to
show steady improvement. The number of people filing initial unemployment claims
is at the lowest level since the boom years of 2005-06, the number of job
openings is at the highest level since 2001, and unemployment is down to just
over 6%. Barring an external shock, we think it is likely that the domestic
economic expansion will continue until the economy reaches full employment.
Until then, remaining labor market slack and moderate capacity utilization offer
the potential for continuing non-inflationary growth.

The global economic picture is somewhat less rosy, as the Russia/Ukraine
conflict is exacting a toll on the European economy, Japan is working through
the impact of a large tax increase, and the growth of China's investment-driven
economy is slowing. On balance, though, we expect the global economy to continue
to grow in the second half of 2014, further supporting the U.S. economy.

While our outlook is constructive, the risk of an adverse "external" shock, such
as a military conflict, remains. While many such risks may already be "priced
into" the market, we caution against complacency and believe investors should
always be prepared for possible market volatility.

At Pioneer, we have long advocated the benefits of staying diversified and
investing for the long term. And while diversification does not assure a profit
or protect against loss in a declining market, we believe there are still
opportunities for prudent investors to earn attractive returns.

2 Pioneer Absolute Return Bond Fund | Annual Report | 8/31/14


On August 11, 2014, I joined Pioneer as the new President and CEO of Pioneer
Investment Management USA, Inc. Since 1928, Pioneer's investment professionals
have worked on behalf of our shareholders to find attractive investment
opportunities, incorporating our proprietary research and prudent risk
management techniques to construct our portfolios.

In my role, I will focus on preserving many of the rich qualities of our
history, while maintaining balance with the demands of this ever-changing world
in which we live.

We greatly appreciate your trust in us and we encourage you to seek investment
guidance and advice from your financial advisor to discuss your goals and
develop an overall investment plan or framework that addresses both your short-
and long-term goals.

Sincerely,

/s/ Lisa M. Jones

                   Pioneer Absolute Return Bond Fund | Annual Report | 8/31/14 3


Portfolio Management Discussion | 8/31/14

In the following interview, portfolio managers Tanguy Le Saout and Cosimo
Marasciulo discuss the factors that influenced Pioneer Absolute Return Bond
Fund's performance for the abbreviated annual reporting period beginning with
the Fund's inception on January 30, 2014 and ending August 31, 2014, as well as
their investment approach in managing the Fund. Mr. Le Saout, Head of European
Fixed Income and a portfolio manager based in Pioneer's Dublin office, and Mr.
Marasciulo, Head of Government Bonds and a portfolio manager at Pioneer, also
based in Dublin, are responsible for the day-to-day management of the Fund.

Q   Can you provide an overview of the Fund's investment approach?

A   Certainly. The big picture is that we aim to have the Fund's annualized
    return exceed that of three-month Treasury bills on a rolling three-year
    annualized basis, while targeting portfolio volatility that is similar to
    that of T-bills as well. To achieve that goal, we seek to provide positive
    absolute Fund returns over most trailing 12-month periods, regardless of
    market conditions.

    Obviously, if we are going to be successful in achieving our objectives, the
    Fund's returns cannot be overly dependent on the price performance of one or
    more fixed-income categories. Therefore, in seeking positive Fund returns
    regardless of market conditions, we divide the portfolio into two distinct
    parts.

    The core of the Fund's portfolio, representing around 70% of assets, is
    currently invested in three-month Treasury bills. The other 30% of assets is
    invested in a range of strategies, each of which is designed to provide the
    Fund with alpha, or excess return. (Alpha is the additional return produced
    from a portfolio manager above that of a passive market index). Each
    strategy is focused on a different segment of the fixed-income market.
    Importantly, each strategy seeks to benefit from both positive and negative
    markets. This means the Fund is positioned in some asset categories within
    the broad bond market through long exposures, while also positioned against
    other asset categories via short exposures. Each alpha-oriented strategy is
    managed independently by a specialist in that particular segment of the
    market who is responsible for implementing his or her individual views.
    This, in our view, provides the Fund with an added level of diversification*
    across different asset classes when compared with investment vehicles where
    asset allocation and security selection are more closely tied together.

*   Diversification does not assure a profit nor protect against loss in a
    declining market.

4 Pioneer Absolute Return Bond Fund | Annual Report | 8/31/14


    Importantly, we closely track the portfolio risks we have assumed across all
    of the alpha-related strategies, and operate within an overall "risk budget"
    for the portfolio based on our objective of avoiding negative Fund returns
    over a 12-month period.

Q   How did the Fund perform during the period between January 30, 2014 and
    August 31, 2014?

A   Pioneer Absolute Return Bond Fund's Class A shares returned -1.20% at net
    asset value during the period between January 30, 2014, and August 31, 2014.
    During the same period, the Fund's benchmark, the Bank of America Merrill
    Lynch (BofA ML) 3-Month U.S. Treasury-Bill Index, returned 0.02%.

Q   Can you review the principal portfolio investment strategies you implemented
    during the Fund's abbreviated annual reporting period ended August 31, 2014,
    and how did those strategies affect the Fund's performance?

A   In addition to the core position in 3-month Treasuries, we have implemented
    a number of different positions across the alpha portion of the Fund's
    portfolio. Looking at the U.S. market, our assessment is that bond prices
    have not reflected the likely extent of interest-rate increases as the U.S.
    Federal Reserve (the Fed) continues to remove its very accommodative
    monetary policy stance. In particular, we expect shorter-term rates to be
    impacted meaningfully once markets digest the outlook for a higher Federal
    funds rate.

    We have used a variety of instruments to implement a portfolio exposure we
    believe will benefit the Fund's performance under such a scenario; notably,
    a short position in the five-year Treasury bond. The positioning was the
    leading detractor from performance during the period from the Fund's
    inception through August 31, 2014, as U.S. rates finished lower. Offsetting
    that underperformance to some degree was currency positioning. We have been
    positioning the Fund in anticipation of the U.S. dollar strengthening
    against other major currencies, including the euro, the British pound and
    the Japanese yen, and that stance added to performance during the
    abbreviated annual reporting period.

    The Fund's quantitative fixed-income strategies contributed positively to
    performance during the period. In particular, we implemented a number of
    successful trades using a multi-factor model that seeks to predict bond
    prices in major global markets based on economic and financial market
    variables. For example, our momentum-based model that seeks to predict price
    trends in the German 10-year bond worked out well and contributed to the
    Fund's performance.

                   Pioneer Absolute Return Bond Fund | Annual Report | 8/31/14 5


    The Fund's inflation strategy added to returns during the period, as we
    positioned the portfolio for an overall rise in inflation to more normal
    levels in major markets, including the U.S. We are maintaining this stance
    on the view that Europe's economy has likely bottomed out, and in
    recognition that Japan's policymakers continue to strongly focus on
    promoting consumption. A number of trades that paired a long portfolio
    position in the credit of one issuer with a short position in the credit of
    another issuer within the same industry also performed well during the
    annual reporting period.

    Our efforts to implement relative value trades that sought to benefit from
    anomalies, either along a single country's yield curve or between the yield
    curves of two countries, detracted from the Fund's results during the
    period. Finally, we positioned the Fund for a rise in U.K. interest rates,
    given the robust recovery there, but so far that positioning has been a
    negative factor in the Fund's performance.

Q   What is your assessment of the current macroeconomic climate and the
    opportunities it may present?

A   We continue to expect volatility to be a feature of the investment backdrop
    as it becomes even clearer that the Fed is no longer prepared to step in and
    backstop conditions each time there is a run of disappointing economic
    releases. The Fed's bond purchases (quantitative easing) are on a track to
    cease by the end of the calendar year, and Fed Chair Yellen recently
    suggested an increase in the Federal funds rate could follow a few months
    after the tapering of quantitative easing is complete. In our view, the
    markets have not fully digested the implications of this policy shift for
    U.S. interest rates, or for the U.S. dollar as rates rise.

    Europe continues to deal with a two-tier economy, despite its common
    currency. The European Central Bank (ECB) is focused on avoiding deflation,
    having implemented interest-rate cuts and recently announced a possible
    program of asset-backed security purchases. We do not expect the ECB to
    engage in full-blown quantitative easing involving sovereign-bond purchases,
    however, and at current levels we do not see value in European bonds
    overall.

    These are among the macroeconomic factors we will monitor closely as we
    structure the alpha portion of the Fund's portfolio.

6 Pioneer Absolute Return Bond Fund | Annual Report | 8/31/14


Please refer to the Schedule of Investments on pages 16-25 for a full listing of
Fund securities.

All investments are subject to risk, including the possible loss of principal.
Pioneer Absolute Return Bond invests in derivatives, such as options, futures,
inverse floating-rate obligations, and swaps, among others, which can be
illiquid, may disproportionately increase losses, and have a potentially large
impact on the performance of the portfolio.

The Fund may take short positions, which involves leverage of its assets and
presents additional risks.

The Fund may invest in credit default swaps, which may in some cases be
illiquid, and they increase credit risk since the Fund has exposure to both the
issuer of the referenced obligation and the counterparty to the credit default
swap.

The Fund employs leverage, which increases the volatility of investment returns
and subjects the Fund to magnified losses.

The Fund is subject to duration risk. Duration seeks to measure the price
sensitivity of a fixed income security to interest rates. The longer a
portfolio's duration, the more sensitive it will be to changes in interest
rates.

Investments in fixed-income securities involve interest rate, credit, inflation,
and reinvestment risks.

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 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.

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.

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

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

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

The Fund may invest in subordinated securities, which may be disproportionately
adversely affected by a default or even a perceived decline in creditworthiness
of the issuer.

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

                   Pioneer Absolute Return Bond Fund | Annual Report | 8/31/14 7


The Fund may invest in event-linked bonds, on 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 Fund may invest in floating-rate loans; the value of collateral, if any,
securing a floating-rate loan can decline or may be insufficient to meet the
issuer's obligations or may be difficult to liquidate.

The Fund is non-diversified, which means that it can invest a large percentage
of its assets in the securities of any one or more issuers. This increases the
Fund's potential risk exposure.

There is no assurance that these and other strategies used by the Fund will be
successful. The Fund is not intended to outperform stocks and bonds during
strong market rallies. Please see the prospectus for a more complete discussion
of the Fund's risks.

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

future results, and there is no guarantee that market forecasts discussed will

Index Definitions
--------------------------------------------------------------------------------
The Bank of America Merrill Lynch (BofA ML) 3-month US Treasury Bill Index is an
unmanaged market index of U.S. Treasury securities maturing in 90 days, that
assumes reinvestment of all income. 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 11-13.

* The Fund commenced operations on January 30, 2013.

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 February 1, 2015, 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.

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 1.01%,
    1.75% 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 partial year period).

Hypothetical Example for Comparison Purposes

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

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

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

     Level 1 - quoted prices in active markets for identical securities.

     Level 2 - other significant observable inputs (including quoted prices for
               similar securities, interest rates, prepayment speeds, credit
               risk, etc.) See Notes to Financial Statements -- Note 1A.

               assumptions in determining fair value of investments) See Notes
               to Financial Statements -- Note 1A.

Generally, equity securities are categorized as Level 1, fixed income securities

Notes to Financial Statements | 8/31/14

1. Organization and Significant Accounting Policies

Pioneer Absolute Return Bond Fund (the Fund) is one of five portfolios
comprising Pioneer Series Trust V, a Delaware statutory trust. The Fund is
registered under the Investment Company Act of 1940 as a diversified, open-end
management investment company. The Fund's investment objective is to seek total
return.

The Fund offers three classes of shares designated as Class A, Class C and Class
Y shares. Class A, Class C and Class Y shares were first publicly offered on
January 31, 2014. 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 gains and losses on investments during the reporting
period. Actual results could differ from those estimates.

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

                  Pioneer Absolute Return Bond Fund | Annual Report | 8/31/14 33


A.  Security Valuation

    Security transactions are recorded as of trade date. The net asset value of
    the Fund is computed once daily, on each day the New York Stock Exchange
    (NYSE) is open, as of the close of regular trading on the NYSE. Senior
    floating rate loan interests (senior loans) are valued in accordance with
    guidelines established by the Board of Trustees at the mean between the last
    available bid and asked prices from one or more brokers or dealers as
    obtained from Loan Pricing Corporation, an independent pricing service. 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. Fixed income securities with
    remaining maturity of more than sixty days are valued at prices supplied by
    independent pricing services, which consider such factors as market prices,
    market events, quotations from one or more brokers, Treasury spreads,
    yields, maturities and ratings. Valuations may be supplemented by dealers
    and other sources, as required. Equity securities that have traded on an
    exchange are valued at the last sale price on the principal exchange where
    they are traded. Equity securities that have not traded on the date of
    valuation, or securities for which sale prices are not available, generally
    are valued using the mean between the last bid and asked prices. Short-term
    fixed income securities with remaining maturities of sixty days or less
    generally are valued at amortized cost. Shares of money market mutual funds
    are valued at such funds' net asset value.

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

    Securities or loan interests for which independent pricing services are
    unable to supply prices or for which market prices and/or quotations are not
    readily available or are considered to be unreliable are valued by a fair
    valuation team comprised of certain personnel of Pioneer Investment
    Management, Inc. (PIM), the Fund's investment advisor, pursuant to
    procedures adapted 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.

34 Pioneer Absolute Return Bond Fund | Annual Report | 8/31/14


    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
    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 August 31, 2014, no securities were valued using fair value methods
    (other than securities valued using prices supplied by independent pricing
    services).

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

    Dividend income is recorded on the ex-dividend date except that certain
    dividends from foreign securities where the ex-dividend date may have passed
    are recorded as soon as the Fund becomes aware of the ex-dividend data in
    the exercise of reasonable diligence. Interest income is recorded on the
    accrual basis.

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

B.  Foreign Currency Translation

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

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

                  Pioneer Absolute Return Bond Fund | Annual Report | 8/31/14 35


C.  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
    August 31, 2014 was $304,141. 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 appreciation or depreciation. 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. The use of futures contracts
    involves, to varying degrees, elements of market, interest rate, currency
    exchange rate and counterparty risks, which may exceed the amounts
    recognized by the Fund. Changes in value of the contracts may not directly
    correlate to changes in value of the underlying securities. The average
    value of contracts open during the period ended August 31, 2014 was
    $24,679,727.

    At August 31, 2014, open futures contracts were as follows:

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 5).

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 taxable income and net realized capital gains, if any, to its
    shareowners. Therefore, no federal income tax provision is required. As of
    August 31, 2014, the Fund did not accrue any interest or penalties with
    respect to unrecognized 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
    August 31, 2014, the Fund reclassified $69,173 to increase accumulated net
    investment loss, $89,618 to decrease accumulated net realized loss on
    investments, foreign currency transactions, swap contracts, written options
    and futures contracts and $20,445 to decrease paid-in capital to reflect
    permanent book/tax differences. These adjustments have no impact on the net
    assets or results of operations.

    At August 31, 2014, the Fund was permitted to carry forward $297,922 of
    long-term losses and $276,319 of short-term losses without limitation.

                  Pioneer Absolute Return Bond Fund | Annual Report | 8/31/14 37


    There were no distributions paid during the fiscal year ended August 31,
    2014.

    The following shows the components of distributable earnings (losses)
    on a federal income tax basis at August 31, 2014:



    --------------------------------------------------------------------------------
                                                                               2014
    --------------------------------------------------------------------------------
                                                                      
    Distributable earnings:
    Undistributed ordinary income                                        $   83,945
    Capital loss carryforward                                              (574,241)
    Unrealized appreciation                                                 254,423
    --------------------------------------------------------------------------------
        Total                                                            $ (235,873)
    ================================================================================


    The difference between book-basis and tax-basis net unrealized appreciation
    is attributable to the tax adjustments relating to credit default swaps and
    the mark to market of futures contracts and credit default swaps.

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 no underwriting commissions on the sale of Class A shares during the
    period ended August 31, 2014.

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 transfer agent, Pioneer Investment Management Shareholder
    Services, Inc. (PIMSS), for its services are allocated among the classes of
    shares based on the number of accounts in each class and the ratable
    allocation of related out-of-pocket expenses (see Note 3).

    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

    Investing in foreign and/or emerging markets securities involves risks
    relating to interest rates, currency exchange rates and economic and
    political conditions. 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 prospectus contains unaudited information regarding the Fund's
    principal risks. Please refer to that document when considering the Fund's
    principal risks.

I.  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 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 option contracts open during the period ended
    August 31, 2014 was $4,815. Written call and put option contracts
    outstanding at period end are listed at the end of the Fund's schedule of
    investments.

    The Fund held three written put option contracts that were open at August
    31, 2014. If the put options were exercised at August 31, 2014, the maximum

J.  Purchased Options

    The Fund may purchase put and call options to seek increase total return.
    Purchased call and put options entitle the Fund to buy and sell a specified
    number of shares or units of a particular security, currency or index at a
    specified price at a specific date or within a specific period of time. Upon
    the purchase of a call or put option, the premium paid by the Fund is
    included in the Statement of Assets and Liabilities as an investment. All
    premiums are marked-to-market daily, and any unrealized gains or losses are
    recorded in the Fund's financial statements. As the purchaser of an index
    option, the Fund has the right to receive a cash payment equal to any
    depreciation in the value of the index below the strike price of the option
    (in the case of a put) or equal to any appreciation in the value of the
    index over the strike price of the option (in the case of a call) as of the
    valuation date of the option. Premiums paid for purchased calls and put
    options which have expired are treated as realized losses on investments in
    the Statement of Operations. Upon the exercise or closing of a purchased put
    option, the premium is offset against the proceeds on the sale of the
    underlying security or financial instrument in order to determine the
    realized gain or loss on investments. Upon the exercise or closing of a
    purchased call option, the premium is added to the cost of the security or
    financial instrument. The risk associated with purchasing options is limited
    to the premium originally paid. The average value of purchased options open
    during the period ended August 31, 2014 was $39,770. Purchased option
    contracts outstanding at period end are listed at the end of the Fund's
    schedule of investments.

K.  Written Interest Rate Swaptions

    The Fund may enter into interest rate swaptions to seek to manage exposure
    to fluctuations in interest rates or to seek to enhance yield. A swaption
    grants the right but not the obligation to enter into the underlying swap at
    a future specified date.

40 Pioneer Absolute Return Bond Fund | Annual Report | 8/31/14


    When the Fund writes a swaption, the Fund receives a premium and becomes
    obligated to enter into a swap contract according to the terms of the
    underlying agreement. The premium received by the Fund is recorded as a
    liability and is subsequently adjusted to the current value of the written
    swaption. Premiums received from writing swaptions that expire unexercised
    are treated by the Fund on the expiration date as realized gains. The
    difference 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 written swaption is
    exercised, the cost basis of the swap is adjusted by the amount of premium
    received. The Fund as writer of a swaption bears the market risk of an
    unfavorable change in the price of the security underlying the written
    swaption.

    Open interest rate swaption contracts at August 31, 2014 are listed in the
    Schedule of Investments. The average value of written swaption contracts
    open during the period ended August 31, 2014 was $100,490.

    The Fund held one interest rate swaption that was open at August 31, 2014.
    If the swaption were exercised at August 31, 2014, the maximum amount the
    Fund would have been required to pay was $200,002.

    Transactions in interest rate swaptions for the period ended August 31, 2014
    are summarized as follows:



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

L.  Purchased Interest Rate Swaptions

    The Fund may purchase put and call swaptions in order to attempt to hedge
    against changes in the value of portfolio securities or to seek to increase
    total return. Purchased call and put swaptions entitle the Fund to buy and
    sell a specified number of shares or units of a particular security,
    currency or index at a specified price at a specific date or within a
    specific period of time. Upon the purchase of a call or put swaption, the
    premium paid by the Fund is included in the Statement of Assets and
    Liabilities as an investment. All premiums are marked-to-market daily, and
    any unrealized gains or losses are recorded in the Fund's financial
    statements. As the purchaser of an index swaption, the Fund has the right to
    receive a cash payment equal to any depreciation in the value of the index
    below the strike price of the swaption

                  Pioneer Absolute Return Bond Fund | Annual Report | 8/31/14 41


    (in the case of a put) or equal to any appreciation in the value of the
    index over the strike price of the swaption (in the case of a call) as of
    the valuation date of the swaption. Premiums paid for purchased calls and
    put swaptions which have expired are treated as realized losses on
    investments in the Statement of Operations. Upon the exercise or closing of
    a purchased put swaption, the premium is offset against the proceeds on the
    sale of the underlying security or financial instrument in order to
    determine the realized gain or loss on investments. Upon the exercise or
    closing of a purchased call swaption, the premium is added to the cost of
    the security or financial instrument. The risk associated with purchasing
    swaptions is limited to the premium originally paid. The average value of
    contracts open during the period ended August 31, 2014 was $220,479.
    Purchased swaptions open at period end are listed at the end of the Fund's
    Schedule of Investments.

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 buy or
    sell credit default swap contracts to seek to increase the Fund's income, or
    to attempt to hedge the risk of default on Fund 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 rights to receive a contingent payment. An upfront payment
    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.

42 Pioneer Absolute Return Bond Fund | Annual Report | 8/31/14


    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.

    Open credit default swap contracts at August 31, 2014 are listed in the
    Schedule of Investments. The average value of credit default swap contracts
    open during the period ended August 31, 2014 was $48,942.

N.  Cross Currency Swap Contracts

    The Fund may enter into a cross currency swap contract to attempt to manage
    and/or gain exposure to fluctuations in interest and/or currency exchange
    rates. When entering into a cross currency swap contract, the Fund
    negotiates with the counterparty to exchange a periodic stream of payments
    (determined using fixed or floating rates) based on the notional amount of
    two different currencies. The notional amounts are typically determined
    based on exchange rates at the opening of the contract.

    Cross currency 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 under the contract or upon
    termination of the contract are recognized, net of the appropriate amount of
    any upfront payment, as realized gains or losses in the Statement of
    Operations. Cross currency swaps are subject to counterparty risk.

    Open cross currency swap contracts at August 31, 2014 are listed in the
    Schedule of Investments. The average value of cross currency swap contracts
    open during the period ended August 31, 2014 was $4,802.

                  Pioneer Absolute Return Bond Fund | Annual Report | 8/31/14 43


O.  Inflation Rate Swap Contracts

    The Fund may enter into inflation rate swap contracts to attempt to hedge
    against inflation. Pursuant to the inflation rate swap agreement, the Fund
    negotiates with a counterparty to exchange a periodic stream of payments,
    based on a benchmark inflation index. One cash flow stream will typically be
    a floating rate payment linked to the specified inflation index while the
    other is typically a fixed interest rate.

    Inflation rate 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. Inflation rate swaps are normally issued on a zero coupon basis
    where all payments compound during the life of the contract and are netted
    upon the termination or maturity of the contract. Final payments received or
    paid by the Fund are recorded as realized gains or losses in the Statement
    of Operations. Inflation rate swap contracts are subject to movements in
    interest rates.

    Open inflation rated swap contracts at August 31, 2014 are listed in the
    Schedule of Investments. The average value of inflation rate swap contracts
    open during the period ended August 31, 2014 was $3,300.

P.  Interest Rate Swap Contracts

    The Fund may enter into interest rate swaps to attempt to hedge against
    interest rate fluctuations or to enhance its income. Pursuant to the
    interest rate swap agreement, the Fund negotiates with a counterparty to
    exchange a periodic stream of payments based on a benchmark interest rate.
    One cash flow stream will typically be a floating rate payment based upon
    the specified floating benchmark interest rate while the other is typically
    a fixed interest rate. Payment flows are usually netted against each other,
    with the difference being paid by one party to the other on a monthly basis.

    Periodic payments received or paid by the Fund are recorded as realized
    gains or losses in the Statement of Operations. Interest rate 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. Interest rate swap
    contracts are subject to counterparty risk and movements in interest rates.

    Open interest rate swap contracts at August 31, 2014 are listed in the
    Schedule of Investments. The average value of interest swap swap contracts
    open during the period ended August 31, 2014 was $34,282.

Report of Independent Registered Public Accounting Firm

To the Board of Trustees of Pioneer Series Trust V and the Shareowners of
Pioneer Absolute Return Bond Fund:
--------------------------------------------------------------------------------

We have audited the accompanying statement of assets and liabilities of Pioneer
Absolute Return Bond Fund (the "Fund"), one of the portfolios constituting
Pioneer Series Trust V, including the schedule of investments, as of August 31,
2014, and the related statements of operations and changes in net assets, and
the financial highlights for the period January 30, 2014, (commencement of
operations) through August 31, 2014. 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 audit.

We conducted our audit 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 audit 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 August 31, 2014, by correspondence with the custodian
and brokers; where replies were not received from brokers, we performed other
auditing procedures. We believe that our audit provides 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 Absolute Return Bond Fund as of August 31, 2014, and the results of its
operations, the changes in its net assets, and the financial highlights for the
period January 30, 2014, (commencement of operations) through August 31, 2014,
in conformity with accounting principles generally accepted in the United States
of America.

President's Letter

Dear Shareowner,

As we move into the final few months of 2014, we remain confident that U.S.
economic growth remains sustainable, if moderately paced. The weather-related
slowdown in the first quarter is behind us and labor market data continues to
show steady improvement. The number of people filing initial unemployment claims
is at the lowest level since the boom years of 2005-06, the number of job
openings is at the highest level since 2001, and unemployment is down to just
over 6%. Barring an external shock, we think it is likely that the domestic
economic expansion will continue until the economy reaches full employment.
Until then, remaining labor market slack and moderate capacity utilization offer
the potential for continuing non-inflationary growth.

The global economic picture is somewhat less rosy, as the Russia/Ukraine
conflict is exacting a toll on the European economy, Japan is working through
the impact of a large tax increase, and the growth of China's investment-driven
economy is slowing. On balance, though, we expect the global economy to continue
to grow in the second half of 2014, further supporting the U.S. economy.

While our outlook is constructive, the risk of an adverse "external" shock, such
as a military conflict, remains. While many such risks may already be "priced
into" the market, we caution against complacency and believe investors should
always be prepared for possible market volatility.

At Pioneer, we have long advocated the benefits of staying diversified and
investing for the long term. And while diversification does not assure a profit
or protect against loss in a declining market, we believe there are still
opportunities for prudent investors to earn attractive returns.

2 Pioneer Global Equity Fund | Annual Report | 8/31/14


On August 11, 2014, I joined Pioneer as the new President and CEO of Pioneer
Investment Management USA, Inc. Since 1928, Pioneer's investment professionals
have worked on behalf of our shareholders to find attractive investment
opportunities, incorporating our proprietary research and prudent risk
management techniques to construct our portfolios.

In my role, I will focus on preserving many of the rich qualities of our
history, while maintaining balance with the demands of this ever-changing world
in which we live.

We greatly appreciate your trust in us and we encourage you to seek investment
guidance and advice from your financial advisor to discuss your goals and
develop an overall investment plan or framework that addresses both your short-
and long-term goals.

Sincerely,

/s/ Lisa M. Jones

Portfolio Management Discussion | 8/31/14

In the following interview, portfolio managers Marco Pirondini and David Glazer
discuss the factors that influenced the performance of Pioneer Global Equity
Fund during the 12-month period ended August 31, 2014. Mr. Pirondini, Head of
Equities, U.S., Executive Vice President and a portfolio manager at Pioneer, and
Mr. Glazer, a Senior Vice President and a portfolio manager at Pioneer, are
responsible for the day-to-day management of the Fund.

Q   How did the Fund perform during the 12-month period ended August 31, 2014?

A   Pioneer Global Equity Fund's Class A shares returned 26.13% at net asset
    value during the 12-month period ended August 31, 2014, while the Fund's
    benchmark, the Morgan Stanley Capital International (MSCI) World (ND) Index
    (the MSCI Index)(1), returned 21.10%. During the same period, the average
    return of the 54 mutual funds in Lipper's Global Large-Cap Core Funds
    category was 19.38%, and the average return of the 1,102 mutual funds in
    Morningstar's World Stock Funds category was 19.51%.

Q   How would you characterize the global equity markets during the 12-month
    period ended August 31, 2014?

A   The past 12 months were characterized for the most part by continued "easy"
    monetary policy on the part of global central banks, although for a short
    time the European Central Bank (ECB) went in the other direction and
    tightened policy. Largely favorable policies from central banks paved the
    way for positive equity performance, especially in the case of U.S. stocks.
    The U.S. economy performed fairly well during the 12-month period, with the
    exception of the first quarter of 2014, when severe winter weather in many
    parts of the country hurt the U.S. growth rate. The positive economic
    performance, including declining unemployment, occurred despite the fact
    that government fiscal policy emphasized reducing the U.S.

    budget deficit, which at times acted as a drag on growth. Elsewhere, some
    European countries fell back toward recession; however, toward the end of
    the Fund's fiscal year, the ECB significantly eased its policies in the hope
    of spurring a recovery. And despite increased geopolitical tensions, market
    participants, by and large, did not make their "buy" or "sell" decisions
    based on events in the Ukraine, Syria, Iraq or Gaza.

Q   Would you review the Fund's overall investment approach?

A   When picking investments for the portfolio we examine mid-and
    large-capitalization stocks worldwide, including those located in the
    emerging markets. From there, we build a diversified* portfolio. We look for
    stocks that we think can provide "growth at a reasonable price," and so
    there is a strong value component to our analysis. We seek to invest the
    Fund in companies that are not only benefiting from operating efficiencies
    as reflected in factors such as increased market share and revenues, but
    that are also employing their capital efficiently. In particular, we
    emphasize strong free cash flow, because that provides companies with the
    flexibility to make share buybacks, reinvest in their businesses, make
    acquisitions, and raise dividends**. We also look for stocks with attractive
    dividend yields as well as those trading at below-market valuations.

    Finally, we attempt to assess not only the potential price gains for each
    stock, but also the stock's potential for a decline in price if
    circumstances become unfavorable. We prefer stocks with the highest
    potential upside, relative to their downside.

Q   Which of your investment decisions had the biggest effects on the Fund's
    performance during the 12-month period ended August 31, 2014?

A   In the latter months of the period, we gradually increased the Fund's
    exposure to U.S. stocks and reduced its European positions, which
    significantly boosted performance. Over the full 12-month period, the Fund
    displayed positive performance in nine of 10 equity market sectors. Stock
    selection in the consumer discretionary, consumer staples and industrials
    sectors contributed to returns, while stock selection within the energy
    sector detracted.

    Regarding individual stock selection, the Fund's position in the packaged
    drink distributor Keurig Green Mountain represented the biggest contributor
    to performance during the period. Investors reacted very positively to news
    that Keurig Green Mountain had entered into an agreement with Coca-Cola to
    add packaged soft drinks to their existing line

    of coffee products. In addition, the portfolio's holdings in American
    Airlines represented a major contributor to returns during the period. The
    recent merger of US Airways and American's former parent (AMR Corp.) was
    strongly endorsed by market participants, who look forward to the prospect
    of US Airways' recognized efficiency and superior management bolstering
    American's bottom line.

    In contrast, the Fund's exposure to Samsung detracted from performance
    during the period. The company has not performed well for the Fund, despite
    its inexpensive valuation at the time we added it to the portfolio.
    Additionally, the Fund's positions in Japanese banks Mitsubishi UFJ
    Financial Group and Sumitomo were hurt by increased competition in the
    domestic lending business.

Q   What is your outlook for the next several months, and how is that outlook
    reflected in the Fund's positioning?

A   We continue to see positive developments in the United States, as many
    U.S.-based businesses are demonstrating discipline in pursuing growth and
    deploying capital. Therefore, we plan to maintain the Fund's overweight in
    the U.S. We have also increased the portfolio's exposure to Japan. We think
    that country's aggressive monetary policies, along with market reforms that
    are being instituted there, will support equity prices.

    In general, equity valuations - despite some pockets of overvalued stocks -
    remain fair to inexpensive. We also believe that global inflation is
    currently not a concern. Assuming that any geopolitical shocks remain
    relatively contained, we anticipate a favorable investment environment for
    global equities during the coming months. In light of our views, we plan to
    continue to position the Fund's portfolio with an eye toward taking
    advantage of advances in the global economy.

Please refer to the Schedule of Investments on pages 16-24 for a full listing of
fund securities.

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

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.

Investments in small and mid-sized companies may offer the potential for higher
returns, but are also subject to greater short-term price fluctuations than
larger, more established companies.

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.

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.

The Morgan Stanley Capital International (MSCI) World ND Index is an unmanaged
measure of the performance of stock markets in the developed world. 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 on pages 10-13.

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 sales charges been reflected. POP returns reflect
deduction of maximum 5.75% sales charge. All results are historical and assume
the reinvestment of dividends and capital gains. Other share classes are
available for which performance and expenses will differ.

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

The net expense ratio reflects the contractual expense limitation currently in
effect through January 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.

Performance shown for periods prior to the inception of the Fund's Class Y
shares on December 31, 2008, is the NAV performance of the Fund's Class A
shares. The performance does not reflect differences in expenses, including the
Rule 12b-1 fees applicable to Class A shares. Since fees for Class A shares are
generally higher than those of Class Y shares, the performance for Class Y
shares prior to their inception would have been higher than the performance
shown. For the period beginning December 31, 2008, 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 net expense ratio reflects the contractual expense limitation currently in
effect through January 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.

                         Pioneer Global Equity Fund | Annual Report | 8/31/14 13


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 and
    redemption fees.

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 1.35%, 2.25%,
    2.25%, and 0.85% for Class A, Class B, 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) or redemption fees that are charged at the time of the trans-
action. 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 | 8/31/14

1. Organization and Significant Accounting Policies

Pioneer Global Equity Fund, formerly Pioneer Global Select Equity Fund (the
Fund), is one of five portfolios comprising Pioneer Series Trust V, a Delaware
statutory trust. The Fund is registered under the Investment Company Act of 1940
as a diversified, open-end management investment company. The Fund commenced
operations on December 15, 2005. The Fund's investment objective is to seek
long-term capital growth.

The Fund offers four classes of shares designated as Class A, Class B, Class C
and Class Y shares. Class Y shares were first publicly offered on December 31,
2008. Effective as of the close of business on December 31, 2009, Class B shares
are no longer offered to new or existing shareholders, except that dividends
and/or capital gain distributions may continue to be reinvested in Class B
shares, and shareholders may exchange their Class B shares for Class B shares of
other Pioneer funds, as permitted by existing exchange privileges. Each class of
shares represents an interest in the same portfolio of investments of the Fund
and has identical rights (based on relative net asset values) to assets and
liquidation proceeds. Share classes can bear different rates of class-specific
fees and expenses such as transfer agent and distribution fees. Differences in
class-specific fees and expenses will result in differences in net investment
income and, therefore, the payment of different dividends from net investment
income earned by each class. The Amended and Restated Declaration of Trust of
the Fund gives the Board the flexibility to specify either per-share voting or
dollar-weighted voting when submitting matters for shareholder approval. Under
per-share voting, each share of a class of the Fund is entitled to one vote.
Under dollar-weighted voting, a shareholder's voting power is determined not by
the number of shares owned, but by the dollar value of the shares on the record
date. Each share class has exclusive voting rights with respect to matters
affecting only that class, including with respect to the distribution plan for
that class. There is no distribution plan for Class Y shares. Class B shares
convert to Class A shares approximately eight years after the date of purchase.

The Fund's financial statements have been prepared in conformity with U.S.
generally accepted accounting principles that require the management of the Fund
to, among other things, make estimates and assumptions that affect the reported
amounts of assets and liabilities, the disclosure of contingent assets

                         Pioneer Global Equity Fund | Annual Report | 8/31/14 33


and liabilities at the date of the financial statements, and the reported
amounts of income, expenses and gain or loss on investments during the reporting
period. Actual results could differ from those estimates.

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

A.  Security Valuation

    Security transactions are recorded as of trade date. The net asset value of
    the Fund is computed once daily, on each day the New York Stock Exchange
    (NYSE) is open, as of the close of regular trading on the NYSE. In computing
    the net asset value, securities that have traded on an exchange are valued
    using the last sale price on the principal exchange where they are traded.
    Securities that have not traded on the date of valuation, or securities for
    which sale prices are not available, generally are valued using the mean
    between the last bid and asked prices. Short-term fixed income securities
    with remaining maturities of sixty days or less generally are valued at
    amortized cost. Shares of money market mutual funds are valued at such
    funds' net asset value.

    The Fund invests primarily in securities of non-U.S. issuers. The principal
    exchanges and markets for such securities have closing times prior to the
    close of the NYSE. However, the value of these securities may be influenced
    by changes in global markets occurring after the closing times of the local
    exchanges and markets up to the time the Fund determines its net asset
    value. Consequently, the Board of Trustees of the Fund has determined that
    daily adjustments to the valuation of securities of non-U.S. issuers by
    utilizing an independent pricing service that supplies an appropriate fair
    value factor is appropriate for the Fund.

    Securities for which independent pricing services are unable to supply
    prices or for which market prices and/or quotations are not readily
    available or are considered to be unreliable are valued 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. 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,

34 Pioneer Global Equity Fund | Annual Report | 8/31/14


    corporate restructurings, natural 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. 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.

    At August 31, 2014, no securities were valued using fair value methods
    (other than securities valued using prices supplied by independent pricing
    services or broker-dealers).

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

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

B.  Federal Income Taxes

    It is the Fund's policy to comply with the requirements of the Internal
    Revenue Code applicable to regulated investment companies and to distribute
    all of its taxable income and net realized capital gains, if any, to its
    shareowners. Therefore, no provision for federal income taxes is required.
    As of August 31, 2014, 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 are subject to examination by
    Federal and State tax authorities.

    In addition to the requirements of the Internal Revenue Code, the Fund may
    also be required to pay local taxes on the recognition of capital gains
    and/or the repatriation of foreign currencies in certain countries. During
    the year ended August 31, 2014, the Fund paid $462 in such taxes.

    In determining the daily net asset value, the Fund estimates the reserve for
    such taxes, if any, associated with investments in certain countries. The
    estimated reserve for the capital gains is based on the net unrealized
    appreciation on certain portfolio securities, the holding period of such
    securities and the related tax rates, tax loss carryforward (if applicable)
    and other such factors. As of August 31, 2014, the Fund had $116,781 in
    reserve related to capital gains.

                         Pioneer Global Equity Fund | Annual Report | 8/31/14 35


    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
    August 31, 2014, the Fund reclassified $743,355 to increase undistributed
    net investment income and $743,355 to increase accumulated net realized loss
    on investments to reflect permanent book/tax differences. These adjustments
    have no impact on net assets or the results of operations.

    At August 31, 2014, the Fund had a net capital loss carryforward of
    $26,144,250, which will expire in 2016 if not utilized.

    During the year ended August 31, 2014, a capital loss carryforward of
    $20,561,506 was utilized to offset net realized gains by the Fund.

    The tax character of distributions paid during the years ended August 31,
    2014 and August 31, 2013, was as follows:



    ----------------------------------------------------------------------------
                                                       2014                 2013
    ----------------------------------------------------------------------------
                                                                
    Distributions paid from:
    Ordinary income                              $2,714,882           $2,291,138
    ----------------------------------------------------------------------------
         Total                                   $2,714,882           $2,291,138
    ============================================================================


    The following shows the components of distributable earnings on a federal
    income tax basis at August 31, 2014:



    ----------------------------------------------------------------------------
                                                                           2014
    ----------------------------------------------------------------------------
                                                                
    Distributable earnings:
    Undistributed ordinary income                                  $  3,900,336
    Capital loss carryforward                                       (26,144,250)
    Net unrealized appreciation                                      23,929,482
    ----------------------------------------------------------------------------
         Total                                                     $  1,685,568
    ============================================================================


    The difference between book-basis and tax-basis net unrealized appreciation
    is attributable to the tax deferral of losses on wash sales and the mark-to-
    market of forwards, futures, and swap contracts.

C.  Fund Shares

    The Fund records sales and repurchases of its shares as of trade date.
    Pioneer Funds Distributor, Inc. (PFD), the principal underwriter for the
    Fund and a wholly owned indirect subsidiary of UniCredit S.p.A. (UniCredit),
    earned $7,781 in underwriting commissions on the sale of Class A shares
    during the year ended August 31, 2014.

36 Pioneer Global Equity Fund | Annual Report | 8/31/14


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

E.  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
    are 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).

F.  Class Allocations

    Income, common expenses and realized and unrealized gains and losses are
    calculated at the Fund level and allocated daily to each class of shares
    based on its respective percentage of adjusted net assets at the beginning
    of the day.

    Distribution fees are calculated based on the average daily net asset value
    attributable to Class A, Class B and Class C shares of the Fund,
    respectively (see Note 4). Class Y shares do not pay distribution fees. All
    expenses and fees paid to the transfer agent, Pioneer Investment Management
    Shareholder Services, Inc. (PIMSS), for its services are allocated among the
    classes of shares based on the number of accounts in each class and the
    ratable allocation of related out-of-pocket expenses (see Note 3).

    Distributions to shareowners are recorded as of the ex-dividend date.
    Distributions paid by the Fund with respect to each class of shares are
    calculated in the same manner and at the same time, except that net
    investment income dividends to Class A, Class B, Class C and Class Y shares
    can reflect different transfer agent and distribution expense rates.

G.  Risks

    Investing in foreign and/or emerging markets securities involves risks
    relating to interest rates, currency exchange rates and economic and
    political conditions. 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 prospectus contains unaudited information regarding the Fund's
    principal risks. Please refer to that document when considering the Fund's
    principal risks.

H.  Futures Contracts

    The Fund may enter into futures transactions in order to attempt to hedge
    against changes in interest rates, securities prices and currency 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
    August 31, 2014 was $ 462,000. 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 appreciation or depreciation. 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. The use of futures
    contracts involves, to varying degrees, elements of market, interest rate,
    currency exchange rate and counterparty risks, which may exceed the amounts
    recognized by the Fund. Changes in value of the contracts may not directly
    correlate to the changes in value of the underlying securities. These risks
    may decrease the effectiveness of the Fund's hedging strategies and
    potentially result in a loss. The average value of contracts open during the
    year ended August 31, 2014 was $2,387,650.

    At August 31, 2014, open futures contracts were as follows:

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


I.  Purchased Options

    The Fund may purchase call and put options in order to attempt to hedge
    against changes in the value of portfolio securities or to seek to increase
    total return. Purchased call and put options entitle the Fund to buy and
    sell a

38 Pioneer Global Equity Fund | Annual Report | 8/31/14


    specified number of shares or units of a particular security, currency or
    index at a specified price at a specific date or within a specific period of
    time. Upon the purchase of a call or put option, the premium paid by the
    Fund is included in the Statement of Assets and Liabilities as an
    investment. All premiums are marked-to-market daily, and any unrealized
    appreciation or depreciation are recorded in the Fund's financial
    statements. As the purchaser of an index option, the Fund has the right to
    receive a cash payment equal to any depreciation in the value of the index
    below the strike price of the option (in the case of a put) or equal to any
    appreciation in the value of the index over the strike price of the option
    (in the case of a call) as of the valuation date of the option. Premiums
    paid for purchased calls and put options which have expired are treated as
    realized losses on investments in the Statement of Operations. Upon the
    exercise or closing of a purchased put option, the premium is offset against
    the proceeds on the sale of the underlying security or financial instrument
    in order to determine the realized gain or loss on investments. Upon the
    exercise or closing of a purchased call option, the premium is added to the
    cost of the security or financial instrument. The risk associated with
    purchasing options is limited to the premium originally paid. The average
    value of contracts open during the year ended August 31, 2014 was $10,812.
    There were no purchased options outstanding at August 31, 2014.

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 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 August 31, 2014
    was $61,487. Written call option contracts outstanding at period end are
    listed at the end of the Fund's schedule of investments. There were no
    written options outstanding at August 31, 2014.


                         Pioneer Global Equity Fund | Annual Report | 8/31/14 39


   Transactions in written options for the year ended August 31, 2014 are
summarized as follows:

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

K.  Total Return Swap Agreements

    The Fund may enter into a total return swap to attempt to manage and/or gain
    exposure to a security or market. Pursuant to a total return swap agreement,
    the Fund negotiates with a counterparty to exchange a periodic stream of
    payments. One party makes payments based on the total return of a reference
    asset (such as a security or a basket of securities or securities index),
    and in return receives fixed or floating rate interest payments. The total
    return of the reference asset typically includes appreciation or
    depreciation on the reference asset, plus any interest or dividend payments.
    To the extent that the total return of the reference asset exceeds or falls
    short of the offsetting interest rate obligation, the Fund will receive a
    payment from or make a payment to the counterparty.

    Total return 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 are recorded as realized gains or
    losses in the Statement of Operations. Total return swap contracts are
    subject to counterparty risk and unanticipated movements in value of
    exchange rates, interest rates, securities or the index.

    Open total return swap contracts at August 31, 2014 are listed in the
    Schedule of Investments. The average value of swap contracts open during the
    year ended August 31, 2014 was $28,563.

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 equal to
0.75% of the Fund's average daily net assets up to $500 million, 0.70% of the
next $500 million of the Fund's average daily net assets and 0.65% of the Fund's
average daily net assets over $1 billion. For the year ended August 31, 2014,
the effective management fee (excluding waivers and/or assumption of expenses)
was equivalent to 0.75% of the Fund's average daily net assets.

40 Pioneer Global Equity Fund | Annual Report | 8/31/14


PIM has contractually agreed to limit ordinary operating expenses of the Fund to
the extent required to reduce Fund expenses to 1.30%, 2.20%, 2.20%, and 0.80% of
the average daily net assets attributable to Class A, Class B, Class C and Class
Y shares, respectively. Fees waived and expenses reimbursed during the year
ended August 31, 2014 are reflected on the Statement of Operations. These
expense limitations are in effect through January 1, 2015. 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 to affiliates" reflected on the Statement of Assets and Liabilities is
$68,855 in management fees, administrative costs and certain other
reimbursements payable to PIM at August 31, 2014.

3. Transfer Agent

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

In addition, the Fund reimburses PIMSS for out-of-pocket expenses incurred by
PIMSS related to shareholder communications activities such as proxy and
statement mailings, outgoing phone calls and omnibus relationship contracts.

For the year ended August 31, 2014, such out-of-pocket expenses by class of
shares were as follows:



--------------------------------------------------------------------------------
Shareholder Communications:
--------------------------------------------------------------------------------
                                                                      
Class A                                                                  $79,600
Class B                                                                    5,800
Class C                                                                   11,600
Class Y                                                                    2,377

  Total:                                                                 $99,377
================================================================================


Included in "Due to affiliates" reflected on the Statement of Assets and
Liabilities is $23,951 in transfer agent fees and out-of-pocket reimbursements
payable to PIMSS at August 31, 2014.

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, Class B and Class C
shares. Pursuant to the Plan, the Fund pays PFD 0.25% of the average daily net
assets attributable to Class A shares as compensation for personal services
and/or account maintenance services or distribution services with regard to
Class A shares. Pursuant to the Plan, the Fund also pays PFD 1.00% of the
average daily net assets attributable to Class B and Class C shares. The fee

                         Pioneer Global Equity Fund | Annual Report | 8/31/14 41


for Class B and Class C shares consists of a 0.25% service fee and a 0.75%
distribution fee paid as compensation for personal services and/or account
maintenance services or distribution services with regard to Class B and Class C
shares. Included in "Due to affiliates" reflected on the Statement of Assets and
Liabilities is $3,248 in distribution fees payable to PFD at August 31, 2014.

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. Class B shares that are redeemed within five years
of purchase are subject to a CDSC at declining rates beginning at 4.00%, based
on the lower of cost or market value of shares being redeemed. Redemptions of
Class C shares within 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 August 31, 2014, CDSCs in the
amount of $3,402 were paid to PFD.

5. Expense Offsets Arrangements

The Fund has entered into certain expense offset arrangements with PIMSS, which
may result in a reduction in the Fund's total expenses due to interest earned on
cash held by PIMSS. For the year ended August 31, 2014, the Fund's expenses were
not reduced under such arrangements.

6. Forward Foreign Currency Contracts

At August 31, 2014, 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 August 31, 2014 was $1,725,316.

Open forward foreign currency contracts at August 31, 2014 were as follows:



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

9. Change in Independent Registered Public Accounting Firm

The Board of Trustees of the Fund, with the approval and recommendation of the
Audit Committee, appointed Deloitte & Touche LLP to serve as the Fund's
independent registered public accounting firm for the fiscal year ending August
31, 2014. Deloitte & Touche LLP replaces Ernst & Young LLP, which resigned as
the Fund's independent registered public accounting firm, effective upon
completion of the audit of the Fund's financial statements for the fiscal year
ended August 31, 2013.

                         Pioneer Global Equity Fund | Annual Report | 8/31/14 45


During the periods that Ernst & Young LLP served as the Fund's independent
registered public accounting firm, including the Fund's fiscal years ended
August 31, 2013 and August 31, 2012, Ernst & Young LLP's reports on the
financial statements of the Fund have not contained an adverse opinion or
disclaimer of opinion and have not been qualified or modified as to uncertainty,
audit scope or accounting principles. Further, there have been no disagreements
with Ernst & Young LLP on any matter of accounting principles or practices,
financial statement disclosure, or auditing scope or procedure, which, if not
resolved to the satisfaction of Ernst & Young LLP would have caused Ernst &
Young LLP to make reference to the subject matter of the disagreement in
connection with its report on the financial statements. In addition, there have
been no reportable events of the kind described in Item 304 (a)(1)(v) of
Regulation S-K under the Securities Exchange Act of 1934.

10. Subsequent Event

Upcoming Conversion of Class B Shares

As of the close of business on November 10, 2014 (the "Conversion Date"), all
outstanding Class B shares of the Pioneer funds will be converted to Class A
shares. Shareholders may continue to hold their Class B shares until the
Conversion Date. Prior to the Conversion Date, redemptions of Class B shares are
subject to any applicable contingent deferred sales charges (CDSCs). Class A
shares acquired through the conversion will not be subject to CDSCs, nor will
any sales charges be assessed in connection with the conversion. After the
Conversion Date, subsequent purchases of Class A shares will be subject to sales
charges as described in the Fund's prospectus.

Report of Independent Registered Public Accounting Firm

To the Board of Trustees of Pioneer Series Trust V
and the Shareowners of Pioneer Global Equity Fund:
--------------------------------------------------------------------------------

We have audited the accompanying statement of assets and liabilities of Pioneer
Global Equity Fund (the "Fund"), one of the portfolios constituting Pioneer
Series Trust V, including the schedule of investments, as of August 31, 2014,
and the related statements of operations and changes in net assets, and the
financial highlights for year 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 audit. The statement of changes in net assets
of the Fund for the year ended August 31, 2013, and the financial highlights for
the years ended August 31, 2013, 2012, 2011 and 2010 were audited by other
auditors. Those auditors expressed an unqualified opinion on those financial
statements and financial highlights in their report dated October 28, 2013.

We conducted our audit 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 audit 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 August 31, 2014, by correspondence with the custodian
and brokers; where replies were not received from brokers, we performed other
auditing procedures. We believe that our audit provides 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 Equity Fund as of August 31, 2014, and the results of its
operations, the changes in its net assets, and the financial highlights for the
year then ended, in conformity with accounting principles generally accepted in
the United States of America.

President's Letter

Dear Shareowner,

As we move into the final few months of 2014, we remain confident that U.S.
economic growth remains sustainable, if moderately paced. The weather-related
slowdown in the first quarter is behind us and labor market data continues to
show steady improvement. The number of people filing initial unemployment claims
is at the lowest level since the boom years of 2005-06, the number of job
openings is at the highest level since 2001, and unemployment is down to just
over 6%. Barring an external shock, we think it is likely that the domestic
economic expansion will continue until the economy reaches full employment.
Until then, remaining labor market slack and moderate capacity utilization offer
the potential for continuing non-inflationary growth.

The global economic picture is somewhat less rosy, as the Russia/Ukraine
conflict is exacting a toll on the European economy, Japan is working through
the impact of a large tax increase, and the growth of China's investment-driven
economy is slowing. On balance, though, we expect the global economy to continue
to grow in the second half of 2014, further supporting the U.S. economy.

While our outlook is constructive, the risk of an adverse "external" shock, such
as a military conflict, remains. While many such risks may already be "priced
into" the market, we caution against complacency and believe investors should
always be prepared for possible market volatility.

At Pioneer, we have long advocated the benefits of staying diversified and
investing for the long term. And while diversification does not assure a profit
or protect against loss in a declining market, we believe there are still
opportunities for prudent investors to earn attractive returns.

                  Pioneer High Income Municipal Fund | Annual Report | 8/31/14 3


Portfolio Management Discussion | 8/31/14

Municipal bonds recovered in value over the first eight months of 2014 after
declining in price late in 2013. In the following interview, David Eurkus and
Jonathan Chirunga discuss the factors that influenced the performance of Pioneer
High Income Municipal Fund during the 12-month period ended August 31, 2014. Mr.
Eurkus, Director of Municipals, a senior vice president and a portfolio manager
at Pioneer, manages the Fund along with Jonathan Chirunga, a vice president and
a portfolio manager at Pioneer.

Q   How did the Fund perform during the 12-month period ended August 31, 2014?

A   Pioneer High Income Municipal Fund's Class A shares returned 7.52% at net
    asset value during the 12-month period ended August 31, 2014, while the
    Fund's benchmark, the Barclays High Yield Municipal Bond Index (the
    Barclays Index), returned 14.74%. During the same period, the average
    return of the 135 mutual funds in Lipper's High Yield Municipal Debt Funds
    category was 14.10%, and the average return of the 178 mutual funds in
    Morningstar's High Yield Municipal Funds category was 13.81%.

Q   How would you describe the investment environment for high-yield
    municipal bonds during the 12-month period ended August 31, 2014?

A   The period saw a remarkable change in market sentiment beginning in
    January 2014, as investors began to believe that fears about credit quality
    and interest-rate volatility had driven down municipal bond prices -
    especially those of higher-yielding municipals - to excessively low
    valuations. Over the first eight months of 2014, lower-rated,
    higher-yielding securities led a dramatic performance revival among
    tax-exempt municipal bonds. The rally was led primarily by growing investor
    confidence about the credit-worthiness of the municipalities and
    institutions issuing tax-exempt bonds, but increased confidence in the
    overall health of the U.S. economy also contributed to the bounce-back.

    Less sanguine sentiments about municipal bonds had prevailed when the
    12-month period began in September 2013. The municipal bond market as well
    as other fixed-income markets had become volatile at that time as investors
    worried that the Federal Reserve's (the Fed's) plans to taper its
    accommodative monetary policies - its quantitative easing bond-buying
    program, in particular - could lead to sharp increases in interest rates and
    a corresponding decline in bond prices. The municipal bond market also took
    a hit from the City of Detroit's well-publicized bankruptcy filing as well
    as from news stories that raised questions about the credit-worthiness of
    the Commonwealth of Puerto Rico's bonds. The numerous concerns combined to
    drive down the prices of municipal bonds during the final months of 2013,
    especially those in the lower-rated, higher-yielding tiers of the market.

4 Pioneer High Income Municipal Fund | Annual Report | 8/31/14


    As noted previously, the municipal market began to change course in
    January 2014, experiencing a rally that essentially continued through the
    end of the 12-month period. Growing investor confidence that the Fed could
    engineer a gradual change in monetary policy without disrupting the markets
    in a meaningful way coincided with the belief that the debt problems of
    Detroit and Puerto Rico were not reflective of conditions in the overall
    municipal market. Thus, market sentiment about the credit-worthiness of
    municipals improved. Investors also recognized that municipal securities
    were selling at very attractive prices relative to the taxable bond market,
    resulting in increased demand from both traditional and non-traditional
    buyers. Municipal bond prices soon began recovering, with high-yield
    municipals bouncing back stronger than the investment-grade segment of the
    market.

Q   What were the main reasons for the Fund's underperformance relative to the
    benchmark Barclays Index during the 12-month period ended August 31, 2014?

A   The Fund participated in the market rebound over the last eight months of
    the period, but not as much as the Barclays Index benchmark, as we
    continued our efforts to restructure the Fund's portfolio, removing both
    real and potentially problem credits while significantly increasing
    diversification*.  The restructuring process had been especially
    challenging when the market was in decline, but was also an issue during
    times when other investors were selling their most liquid and easily
    tradable securities, as those sales affected the values of some of the
    Fund's better-quality positions, such as securities backed by proceeds from
    tobacco settlement liability lawsuits.

    By August 31, 2014, the Fund's portfolio restructuring was essentially
    completed, as our review process continued to weed out problem credits.

    For example, we reduced the Fund's exposure to continuing care retirement
    communities (CCRCs) down to less than 20% by period end, as we sought to
    increase the portfolio's diversification by credit issuer and quality. At
    the same time, we increased the portfolio's exposure to more liquid, easily-
    tradable industries, notably bonds backed by revenues from charter schools,
    tobacco liability settlements, and transportation and hospital projects.
    Consistent with our investment discipline, the portfolio's holdings were
    confined principally to project revenue bonds, which are funded by the
    revenue streams produced by specific public projects. We believe revenue
    bonds are more reliable investments than general obligation bonds, which are
    more exposed to changes in the general financial health of the issuing
    municipalities or public agencies.

*   Diversification does not assure a profit nor protect against loss in a
    declining market.

                  Pioneer High Income Municipal Fund | Annual Report | 8/31/14 5


    Over the final months of the 12-month period, the Fund's performance did
    improve noticeably, in both absolute and benchmark-relative terms. During
    the final six months of the period, for example, the Fund's Class A shares
    generated a total return of 5.27% at net asset value, just slightly behind
    the 5.85% return of the Barclays Index. Unfortunately, the Fund's
    significant underperformance of the benchmark during the first six months of
    the 12-month period proved too difficult to overcome.

Q   What were some of the individual portfolio investments that had noteworthy
    effects on the Fund's performance during the 12-month period ended August
    31, 2014?

A   The Fund saw good results from investments in bonds backed by charter
    schools and hospitals, as well as from some transportation projects.

    Charter school project bonds in the portfolio that fared well during the
    period included securities backed by the Greenwood Charter School in
    Pennsylvania, the Rocky Mountain Charter Academy in Colorado, and the
    Universal Academy in Texas. In the hospital sector, issues that performed
    well for the Fund included project revenue bonds backed by hospitals in
    Pottsville, Pennsylvania, Onondaga County, New York, and Muskingum County in
    Ohio.

    Among the Fund's underperforming securities during the period were CCRC
    bonds backed by projects in Tyler, Texas, and Deerfield, Iowa.

Q   What is your investment outlook?

A   We anticipate that the domestic economy will continue to grow at a
    moderate, but steady pace in the coming months. As key indicators such as
    employment, housing and consumer spending improve, so too should the
    general fiscal health of municipalities and public agencies. That, in turn,
    should buttress the credit quality of the debt issued by those entities.
    While the Fed is likely to begin raising short-term interest rates modestly
    during 2015, we think it will act gradually so as not to disrupt the
    capital markets. We also believe inflation should remain well under control.

    As we enter the final quarter of 2014, the outlook for municipal bonds looks
    good. So far during 2014, issuance of municipal bonds has been down by 15%
    from 2013 levels, and yet demand for municipal bonds has increased
    substantially, which has been a boon for municipal bond prices. Meanwhile,
    the rising tax revenues that accompany a strengthening economy are improving
    the financial health of the government agencies and institutions that issue
    municipal bonds.

    We plan to continue to emphasize fundamental credit research when selecting
    securities for the Fund, while maintaining a well-diversified portfolio of
    investments that adhere to our strictest quality standards.

6 Pioneer High Income Municipal Fund | Annual Report | 8/31/14


Please refer to the Schedule of Investments on pages 15-23 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.

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

The Fund is non-diversified, which means that it can invest a large percentage
of its assets in the securities of any one or more issuers. This increases the
Fund's potential risk exposure.

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.

A portion of income may be subject to local, state, federal, and/or
alternative minimum tax. Capital gains, if any, are subject to a capital
gains tax.

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.

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 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.

12 Pioneer High Income Municipal Fund | Annual Report | 8/31/14


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.

During Period*
--------------------------------------------------------------------------------


*   Expenses are equal to the Fund's annualized expense ratio of 0.90%, 1.66%
    and 0.71% fro 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.

Purchases and sales of securities (excluding temporary cash investments) for the
year ended August 31, 2014 aggregated $269,587,918 and $408,401,993,
respectively.

Various inputs are used in determining the value of the Fund's investments.
These inputs are summarized in the three broad levels listed below.

    Level 1 -- quoted prices in active markets for identical securities.

    Level 2 -- other significant observable inputs (including quoted prices for
               similar securities, interest rates, prepayment speeds, credit
               risk, etc.) See Notes to Financial Statements -- Note 1A.

    Level 3 -- significant unobservable inputs (including the Fund's own
               assumptions in determining fair value of investments) See Notes
               to Financial Statements -- Note 1A.

Generally, equity securities are categorized as Level 1, fixed income securities
and senior loans as Level 2 and securities valued using fair value methods
(other than prices supplied by independent pricing services or broker-dealers)
as Level 3. See Notes to Financial Statements -- Note 1A.

The following is a summary of the inputs used as of August 31, 2014, in valuing
the Fund's investments:

Notes to Financial Statements | 8/31/14

1. Organization and Significant Accounting Policies

Pioneer High Income Municipal Fund (the Fund) is one of five portfolios
comprising Pioneer Series Trust V, a Delaware statutory trust. The Fund is
registered under the Investment Company Act of 1940 as an open-end management
investment company. The Fund is non-diversified. The investment objective of the
Fund is to maximize total return through a combination of income that is exempt
from regular federal income tax and capital appreciation.

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 the flexibility to
specify either per share voting or dollar-weighted voting when submitting
matters for shareholder approval. Under per share voting, each share of a class
of the Fund is entitled to one vote. Under dollar-weighted voting, a
shareholder's voting power is determined not by the number of shares owned, but
by the dollar value of the shares on the record date. Each share class has
exclusive voting rights with respect to matters affecting only that class,
including with respect to the distribution plan for that class. There is no
distribution plan for Class Y shares.

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

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

A.   Security Valuation

     Security transactions are recorded as of trade date. The net asset
     value of the Fund is computed once daily, on each day the New York Stock
     Exchange (NYSE) is open, as of the close of regular trading on the NYSE.
     Fixed income securities with remaining maturity of more than sixty days are
     valued at prices supplied by independent pricing services, which consider
     such factors as market prices, market events, quotations from one or more
     brokers, Treasury spreads, yields, maturities and ratings. Valuations may
     be supplemented by dealers and other sources, as required. Short-term fixed
     income securities with remaining maturities of sixty days or less generally
     are valued at amortized cost.

     Securities for which independent pricing services are unable to supply
     prices or for which market prices and/or quotations are not readily
     available or are considered to be unreliable are valued 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.

     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 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. 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.

     At August 31, 2014, 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).

     Discount and premium on debt securities are accreted or amortized,
     respectively, daily into interest income on a yield-to-maturity basis with
     a corresponding increase or decrease in the cost basis of the security.
     Interest income is recorded on the accrual basis.

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

B.   Federal Income Taxes

     It is the Fund's policy to comply with the requirements of the Internal
     Revenue Code applicable to regulated investment companies and to distribute
     all of its taxable income and net realized capital gains, if any, to its
     shareowners. Therefore, no provision for federal income taxes is required.
     As of August 31, 2014, 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 August 31, 2014, the Fund reclassified $236,780 to increase
     undistributed net investment income, and $236,780 to increase accumulated
     net realized loss on investments to reflect permanent book/tax differences.
     These adjustments have no impact on net assets or the results of
     operations. At August 31, 2014, the Fund was permitted to carry forward
     indefinitely $22,886,636 of short-term losses and $22,112,417 of long-term
     losses under the Regulated Investment Company Modernization Act of 2010
     without limitation. Additionally, at August 31, 2014, the Fund had a net
     capital loss carryforward of $8,649,148 of which the following amounts will
     expire between 2017 and 2018 if not utilized: $2,640,380 in 2017 and
     $6,008,768 in 2018. Since new losses are required to be used first, loss
     carryforwards that are subject to expiration may be more likely to expire
     unused.

     During the year ended August 31, 2014, a capital loss carryforward of
     $3,091,072 was utilized to offset net realized gains by the fund.

     The tax character of distributions paid during the years ended August 31,
     2014 and August 31, 2013 were as follows:



     ---------------------------------------------------------------------------
                                                       2014                 2013
     ---------------------------------------------------------------------------
                                                               
     Distributions paid from:
     Tax-exempt income                          $28,444,745          $40,383,212
     Ordinary income                              1,328,623            2,210,747
     ---------------------------------------------------------------------------
        Total                                   $29,773,368          $42,593,959
     ===========================================================================


                 Pioneer High Income Municipal Fund | Annual Report | 8/31/14 33


     The following shows the components of distributable earnings on a federal
     income tax-basis at August 31, 2014:



     ---------------------------------------------------------------------------
                                                                          2014
     ---------------------------------------------------------------------------
                                                              
     Distributable earnings:
     Undistributed tax-exempt income                             $   8,677,221
     Capital loss carryforward                                     (53,648,201)
     Dividend payable                                                 (551,552)
     Net unrealized depreciation                                    (5,443,840)
     ---------------------------------------------------------------------------
          Total                                                  $ (50,966,372)
     ===========================================================================


     The difference between book-basis and tax-basis net unrealized
     depreciation is attributable to adjustments related to interest on
     defaulted bonds, the tax treatment of premium and amortization and
     tax-basis adjustments on partnerships.

C.   Fund Shares

     The Fund records sales and repurchases of its shares as of trade date.
     Pioneer Funds Distributor, Inc. (PFD), the principal underwriter for the
     Fund and a wholly owned indirect subsidiary of UniCredit S.p.A.
     (UniCredit), earned $68,113 in underwriting commissions on the sale of
     Class A shares during the year ended August 31, 2014.

D.   Class Allocations

     Income, common expenses and realized and unrealized gains and losses
     are calculated at the Fund level and allocated daily to each class of
     shares based on its respective percentage of adjusted net assets at the
     beginning of the day.

     Distribution fees are calculated based on the average daily net asset value
     attributable to Class A and Class C shares of the Fund, respectively (see
     Note 4). Class Y shares do not pay distribution fees. All expenses and fees
     paid to the transfer agent, Pioneer Investment Management Shareholder
     Services, Inc. (PIMSS), for its services are allocated among the classes of
     shares based on the number of accounts in each class and the ratable
     allocation of related out-of-pocket expenses (see Note 3).

     The Fund declares, as daily dividends, substantially all of its net
     investment income. All dividends are paid on a monthly basis.  Short-term
     capital gain distributions, if any, may be declared with the daily
     dividends.  Distributions to shareowners are recorded as of the ex-dividend
     date.  Distributions paid by the Fund with respect to each class of shares
     are calculated in the same

34 Pioneer High Income Municipal Fund | Annual Report | 8/31/14


     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.

E.   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 prospectus
     contains unaudited information regarding the Fund's principal risks. Please
     refer to that document when considering the Fund's principal risks.

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 equal to
0.50% of the Fund's average daily net assets up to $500 million; 0.475% of the
next $500 million of the Fund's average daily net assets and 0.45% of the Fund's
average daily net assets over $1 billion. For the year ended August 31, 2014,
the effective management fee (excluding waivers and/or assumption of expenses)
was equivalent to 0.50% of the Fund's average daily net assets.

PIM has contractually agreed to limit ordinary operating expenses (excluding
taxes, commissions, interest and extraordinary expenses) of the Fund to the
extent required to reduce Fund expenses to 0.90% and 1.80% of the average daily
net assets attributable to Class A shares and Class C shares, respectively.
Class Y shares do not have an expense limitation. These expense limitations are
in effect through January 1, 2015. 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 to affiliates" reflected on the Statement of Assets and Liabilities is
$32,813 in management fees, administrative costs and certain other
reimbursements payable to PIM at August 31, 2014.

3. Transfer Agent

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

                 Pioneer High Income Municipal Fund | Annual Report | 8/31/14 35


In addition, the Fund reimburses PIMSS for out-of-pocket expenses incurred by
PIMSS related to shareholder communications activities such as proxy and
statement mailings, outgoing phone calls and omnibus relationship contracts. For
the year ended August 31, 2014, such out-of-pocket expenses by class of shares
were as follows:



--------------------------------------------------------------------------------
Shareholder Communications:
--------------------------------------------------------------------------------
                                                                     
Class A                                                                 $ 81,991
Class C                                                                   88,884
Class Y                                                                  107,724
--------------------------------------------------------------------------------
  Total                                                                 $278,599
================================================================================


Included in "Due to affiliates" reflected on the Statement of Assets and
Liabilities is $49,781 in transfer agent fees and out-of-pocket reimbursements
payable to PIMSS at August 31, 2014.

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 $22,937 in distribution fees payable to
PFD at August 31, 2014.

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 August 31, 2014, CDSCs in the amount of $44,474 were paid to PFD.

36 Pioneer High Income Municipal Fund | Annual Report | 8/31/14


5. Expense Offset Arrangements

The Fund has entered into certain expense offset arrangements with PIMSS which
may result in a reduction in the Fund's total expenses due to interest earned on
cash held by PIMSS. For the year ended August 31, 2014, the Fund's expenses were
not reduced under such arrangements.

6. Line of Credit Facility

The Fund, along with certain other funds in the Pioneer Family of Funds (the
Funds), participates in a committed, unsecured revolving line of credit
facility. Borrowings are used solely for temporary or emergency purposes. The
Fund may borrow up to the lesser of the amount available under the facility or
the limits set for borrowing by the Fund's prospectus and the 1940 Act. The
credit facility in effect until February 12, 2014 was in the amount of $215
million. As of February 12, 2014, 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 0.90% (0.85% as of
February 12, 2014) on an annualized basis, or the Alternate Base Rate, which is
the greater of (a) the facility's administrative agent's daily announced prime
rate on the borrowing date, (b) 2% plus the Federal Funds Rate on the borrowing
date and (c) 2% plus the overnight Euro dollar rate on the borrowing date. The
Funds pay an annual commitment fee to participate in the credit facility. The
commitment fee is allocated among participating Funds based on an allocation
schedule set forth in the credit agreement. The average borrowings during the
year ended August 31, 2014 was $2,546,301. For the year ended August 31, 2014,
the Fund had no borrowings under the credit agreement.

7. Change in Independent Registered Public Accounting Firm

The Board of Trustees of the Fund, with the approval and recommendation of the
Audit Committee, appointed Deloitte & Touche LLP to serve as the Fund's
independent registered public accounting firm for the fiscal year ending August
31, 2014. Deloitte & Touche LLP replaces Ernst & Young LLP, which resigned as
the Fund's independent registered public accounting firm, effective upon
completion of the audit of the Fund's financial statements for the fiscal year
ended August 31, 2013.

During the periods that Ernst & Young LLP served as the Fund's independent
registered public accounting firm, including the Fund's fiscal years ended
August 31, 2013 and August 31, 2012, Ernst & Young LLP's reports on the
financial statements of the Fund have not contained an adverse opinion or

               Pioneer High Income Municipal Fund | Annual Report | 8/31/14   37


disclaimer of opinion and have not been qualified or modified as to uncertainty,
audit scope or accounting principles. Further, there have been no disagreements
with Ernst & Young LLP on any matter of accounting principles or practices,
financial statement disclosure, or auditing scope or procedure, which, if not
resolved to the satisfaction of Ernst & Young LLP would have caused Ernst &
Young LLP to make reference to the subject matter of the disagreement in
connection with its report on the financial statements. In addition, there have
been no reportable events of the kind described in Item 304 (a)(1)(v) of
Regulation S-K under the Securities Exchange Act of 1934.

38 Pioneer High Income Municipal Fund | Annual Report | 8/31/14


Report of Independent Registered Public Accounting Firm

To the Board of Trustees of Pioneer Series Trust V and the
Shareowners of Pioneer High Income Municipal Fund:
--------------------------------------------------------------------------------

We have audited the accompanying statement of assets and liabilities of Pioneer
High Income Municipal Fund (the "Fund"), one of the portfolios constituting
Pioneer Series Trust V, including the schedule of investments, as of August 31,
2014, and the related statements of operations and changes in net assets, and
the financial highlights for year 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 audit. The statement of changes in net assets
of the Fund for the year ended August 31, 2013, and the financial highlights for
the years ended August 31, 2013, 2012, 2011 and 2010 were audited by other
auditors. Those auditors expressed an unqualified opinion on those financial
statements and financial highlights in their report dated October 28, 2013.

We conducted our audit 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 audit 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 August 31, 2014, by correspondence with the custodian
and brokers; where replies were not received from brokers, we performed other
auditing procedures. We believe that our audit provides 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 High Income Municipal Fund as of August 31, 2014, and the results of its
operations, the changes in its net assets, and the financial highlights for the
year then ended, in conformity with accounting principles generally accepted in
the United States of America.

President's Letter

Dear Shareowner,

As we move into the final few months of 2014, we remain confident that U.S.
economic growth remains sustainable, if moderately paced. The weather-related
slowdown in the first quarter is behind us and labor market data continues to
show steady improvement. The number of people filing initial unemployment claims
is at the lowest level since the boom years of 2005-06, the number of job
openings is at the highest level since 2001, and unemployment is down to just
over 6%. Barring an external shock, we think it is likely that the domestic
economic expansion will continue until the economy reaches full employment.
Until then, remaining labor market slack and moderate capacity utilization offer
the potential for continuing non-inflationary growth.

The global economic picture is somewhat less rosy, as the Russia/Ukraine
conflict is exacting a toll on the European economy, Japan is working through
the impact of a large tax increase, and the growth of China's investment-driven
economy is slowing. On balance, though, we expect the global economy to continue
to grow in the second half of 2014, further supporting the U.S. economy.

While our outlook is constructive, the risk of an adverse "external" shock, such
as a military conflict, remains. While many such risks may already be "priced
into" the market, we caution against complacency and believe investors should
always be prepared for possible market volatility.

At Pioneer, we have long advocated the benefits of staying diversified and
investing for the long term. And while diversification does not assure a profit
or protect against loss in a declining market, we believe there are still
opportunities for prudent investors to earn attractive returns.

2 Pioneer Long/Short Global Bond Fund | Annual Report | 8/31/14


On August 11, 2014, I joined Pioneer as the new President and CEO of Pioneer
Investment Management USA, Inc. Since 1928, Pioneer's investment professionals

opportunities, incorporating our proprietary research and prudent risk
management techniques to construct our portfolios.

In my role, I will focus on preserving many of the rich qualities of our
history, while maintaining balance with the demands of this ever-changing world
in which we live.

We greatly appreciate your trust in us and we encourage you to seek investment
guidance and advice from your financial advisor to discuss your goals and
develop an overall investment plan or framework that addresses both your
short- and long-term goals.

Sincerely,

/s/ Lisa M. Jones

Portfolio Management Discussion | 8/31/14

In the following interview, portfolio managers Thomas Swaney and Benjamin Gord
discuss the factors that influenced Pioneer Long/Short Global Bond Fund's
performance for the abbreviated annual reporting period beginning with the
Fund's inception on December 30, 2013, and ending August 31, 2014, as well as
their investment approach in managing the Fund. Mr. Swaney, Head of Alternative
Fixed Income, U.S., a senior vice president, and a portfolio manager at Pioneer
(lead portfolio manager of the Fund since 2013), and Mr. Gord, a vice president
and a portfolio manager at Pioneer, are responsible for the day-to-day
management of the Fund.

Q    Can you provide an overview of the Fund's approach?

A    The big picture is that we seek to have the Fund produce an average annual
     return that is greater than the return on 3-month Treasury bills, on an
     annualized basis, with volatility lower than one would experience in the
     broad equity market. In pursuing this goal, we seek to have the Fund
     provide positive returns over most trailing 12-month periods and to
     minimize the extent of any negative returns, regardless of market
     conditions.

     Obviously, if we are going to be successful in achieving our objective, the
     Fund's returns cannot be overly dependent on the direction of one or more
     financial asset categories. In seeking positive returns regardless of
     market conditions, we utilize two distinct strategies. One strategy is
     "directional," in that we need to be correct about whether a particular
     asset price is poised to go up or down. However, we seek to have the Fund's
     performance benefit from both positive and negative returns. This means
     that at times we invest the portfolio in some asset categories within the
     broad bond market by taking long positions, while speculating against other
     asset classes by taking short positions.

     The other part of the portfolio utilizes uncorrelated trading strategies,
     in which we do not have to take a stance on whether an individual market is
     going to rise or fall overall. Instead, we need to identify either a
     segment or security within a market that we believe will outperform versus
     another market segment or security. We execute these portfolio investment
     strategies across several different global financial markets and many
     different asset classes. We will seek to "pair" positions, meaning that the
     Fund will have a long position in one segment/security of a particular
     market, and a short position in another segment/security, such that the
     performance of the pair is not dependent on the direction of the market. We
     believe this strategy can allow the Fund to benefit from favorable relative
     performance, regardless of the overall direction of that market.

4 Pioneer Long/Short Global Bond Fund | Annual Report | 8/31/14


     Most importantly, we closely track the risks we have assumed in both
     portions of the portfolio and operate within an overall "risk budget,"
     which is based on our goal of largely avoiding negative returns over a
     12-month period.

Q    How did the Fund perform during the abbreviated annual reporting period
     from December 30, 2013, through August 31, 2014?

A    Pioneer Long/Short Global Bond Fund's Class A shares returned 0.50% at net
     asset value during the period between December 30, 2013, and August 31,
     2014. During the same period, the Fund's benchmark, the Bank of America
     Merrill Lynch (BofA ML) 3-Month U.S. Treasury-Bill Index, returned 0.03%.

Q    Can you review the principal portfolio investment strategies you
     implemented during the Fund's abbreviated annual reporting period ended
     August 31, 2014? How did those strategies help or hinder the Fund's
     performance?

A    We have implemented a number of strategies within the "uncorrelated"
     portion of the Fund's portfolio. The Currency Long/Short strategy has made
     a significant positive contribution to the Fund's benchmark-relative return
     during the first eight months of the Fund's existence. Specifically, the
     portfolio has been "long" the U.S. dollar while shorting the euro. That has
     worked out well as the dollar has strengthened versus other major
     currencies. The portfolio also implemented a number of curve trades in the
     Credit Long/Short strategy, where the Fund is long one part of an
     individual issuer's yield curve and short another, depending on our outlook
     for the issuer's curve to steepen or flatten. That strategy, too, has
     contributed to the Fund's relative returns since inception. We have also
     had pair trades within the strategy, utilizing two issuers within the same
     industry sector for whom we expect performance to diverge. The Fund also
     holds a variety of event-linked (catastrophe) bonds, which are designed to
     pay reasonable yields in exchange for insurance protection against major
     calamities such as hurricanes, floods and earthquakes. We like catastrophe
     bonds for their low correlation to any equity or fixed-income market risks.
     That position also contributed to the Fund's performance over the period.

     The Fund's Cross Asset Relative Value strategy was the leading detractor
     from performance during the period. Under the strategy, we seek to pair
     trades in order to take advantage of any distortions in relative valuation
     between asset classes: for instance, high-yield versus investment-grade
     corporates. The approach has experienced some challenges in the current
     environment of low volatility and narrow credit spreads, which are the
     differences in yield between various fixed-income securities with similar
     maturities. Our long/short trades related to equity and yield curve

                 Pioneer Long/Short Global Bond Fund | Annual Report | 8/31/14 5


     exposures also modestly detracted from the Fund's performance. With regard
     to the latter exposure, we have been shorting a very specific point on the
     U.S. yield curve, as we do not believe the markets are prepared for the
     likely pace of the Federal Reserve's (the Fed's) policy tightening should
     the domestic economy return to above-trend growth.

     In the "directional" side of the portfolio, we have been wary of taking on
     long credit exposure given the spread tightening that has occurred. We
     have, however, held a portfolio position in euro-denominated bonds that are
     convertible into equity. That position gives the Fund exposure to any
     improvement in the European stock market over the next few years, along
     with downside protection. We have also taken positions in select U.S.
     convertible securities, in particular within the biotech/pharmaceutical
     area of the health care sector. More opportunistically, we have traded the
     portfolio in and out of high-yield issues in both the U.S. and Europe.

     The Fund has meaningful exposure to securitized credit markets, such as
     non-agency mortgages, where we see opportunities for the Fund to earn
     reasonable risk-adjusted returns with less sensitivity to the direction of
     the U.S. equity market. Because we seek to hedge out the accompanying
     interest-rate risk, we are isolating the cheapness of mortgage bonds.
     Another directional trade has been to take a long portfolio position in
     asset-sensitive financial companies, while extracting the equity beta from
     those positions using derivatives, along with a corresponding short
     position in large-cap industrial companies. (Beta is a statistical
     measurement of an investment's sensitivity to market movements in relation
     to an index.)

     On the short side of the directional portfolio, we took a position with
     respect to investment-grade debt in both Asia and Australia, which we
     viewed as being vulnerable to the credit slowdown in China. China is
     attempting to grow at a 7.5% rate while contracting credit and relying on a
     shadow banking system. We believed both the Asian and Australian credit
     markets were a prudent and efficient way to get the Fund some short
     exposure to a China policy error. We closed the trade during the period,
     with a modest negative impact on Fund performance.

Q    What is your assessment of the current macroeconomic climate and the
     investment opportunities it may present?

A    Overall, we expect global economic growth to continue to strengthen. In the
     U.S., we are looking for growth to move up into the range of historic
     long-term trends, supported by improvements in employment and the
     availability of credit. At the same time, we believe there will be
     disappointments along the way, and with the Fed no longer committed to
     stepping up its accommodative policies to backstop conditions, asset prices

6 Pioneer Long/Short Global Bond Fund | Annual Report | 8/31/14


     will likely experience significant volatility. Another macroeconomic
     development we are examining is the lack of a clear definition when it
     comes to emerging versus developed markets. Many emerging economies are
     actually in a better position from the standpoint of debt and current-
     account flows, and we anticipate that performance trends in global bond
     markets will become increasingly country-specific.

     More broadly, we would not be surprised to see market volatility and
     performance dispersion increase as global central bank policies diverge and
     as the Fed's tightening transitions from tapering quantitative easing to
     eventually raising interest rates. We believe that scenario could create
     opportunities for an uncorrelated investment strategy such as the Fund's,
     and we will seek to identify trades that can help it to capitalize on these
     emerging themes.

Please refer to the Schedule of Investments on pages 16-29 for a full listing of
Fund securities.

All investments are subject to risk, including the possible loss of principal.

The portfolio may invest in derivative securities, such as options, futures,
inverse floating-rate obligations, and swaps, among others, which can be
illiquid, may disproportionately increase losses, and have a potentially large
impact on the performance of the portfolio.

The Fund may take short positions, which involves leverage of its assets and
presents additional risks.

The Fund may invest in credit default swaps, which may in some cases be
illiquid, and they increase credit risk since the Fund has exposure to both the
issuer of the referenced obligation and the counterparty to the credit default
swap.

The Fund employs leverage, which increases the volatility of investment returns
and subjects the Fund to magnified losses.

Investments in fixed-income securities involve interest rate, credit, inflation,
and reinvestment risks.

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.

                 Pioneer Long/Short Global Bond Fund | Annual Report | 8/31/14 7


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

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

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

The Fund may invest in event-linked bonds, on 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 Fund may invest in floating-rate loans; the value of collateral, if any,
securing a floating-rate loan can decline or may be insufficient to meet the
issuer's obligations or may be difficult to liquidate.

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 is non-diversified, which means that it can invest a large percentage
of its assets in the securities of any one or more issuers. This increases the
Fund's potential risk exposure.

These risks may increase share price volatility.

There is no assurance that these and other strategies used by the Fund will be
successful. Please see the prospectus for a more complete discussion of the
Fund's risks.

and expenses. Contact your advisor or Pioneer Investments for a prospectus or

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 January 1, 2015, 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.

                Pioneer Long/Short Global Bond Fund | Annual Report | 8/31/14 13


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 plus the
    expense ratio of the underlying funds. These combined totals were 1.64%,
    2.39%, and 1.39% for Class A, Class C and Class Y, respectively. These
    combined ratios were multiplied by the average account value over value over
    the period, and then multiplied by 184/365 (to reflect the partial year
    period).

Hypothetical Example for Comparison Purposes

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

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

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

Various inputs are used in determining the value of the Fund's investments.
These inputs are summarized in the three broad levels listed below.

    Level 1 - quoted prices in active markets for identical securities.

    Level 2 - other significant observable inputs (including quoted prices for
              similar securities, interest rates, prepayment speeds, credit
              risk, etc.) See Notes to Financial Statements -- Note 1A.

    Level 3 - significant unobservable inputs (including the Fund's own
              assumptions in determining fair value of investments) See Notes to
              Financial Statements -- Note 1A.

Generally, equity securities are categorized as Level 1, fixed income securities
and senior loans as Level 2 and securities valued using fair value methods
(other than prices supplied by independent pricing services or broker-dealers)
are categorized as Level 3. See Notes to Financial Statements -- Note 1A.

Notes to Financial Statements | 8/31/14

1. Organization and Significant Accounting Policies

Pioneer Long/Short Global Bond Fund (the Fund) is one of five portfolios
comprising Pioneer Series Trust V, a Delaware statutory trust. The Fund is
registered under the Investment Company Act of 1940 as a non-diversified,
open-end management investment company. The Fund's investment objective is to
seek total return.

The Fund offers three classes of shares designated as Class A, Class C, and
Class Y shares. Class A, Class C and Class Y shares were first publicly offered
on December 31, 2013. 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 gains and losses on investments during the reporting
period. Actual results could differ from those estimates.

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

                Pioneer Long/Short Global Bond Fund | Annual Report | 8/31/14 37


A.  Security Valuation

    Security transactions are recorded as of trade date. The net asset value of
    the Fund is computed once daily, on each day the New York Stock Exchange
    (NYSE) is open, as of the close of regular trading on the NYSE. Senior
    floating rate loan interests (senior loans) are valued in accordance with
    guidelines established by the Board of Trustees at the mean between the last
    available bid and asked prices from one or more brokers or dealers as
    obtained from Loan Pricing Corporation, an independent pricing service. 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. Fixed income securities with
    remaining maturity of more than sixty days are valued at prices supplied by
    independent pricing services, which consider such factors as market prices,
    market events, quotations from one or more brokers, Treasury spreads,
    yields, maturities and ratings. Valuations may be supplemented by dealers
    and other sources, as required. Equity securities that have traded on an
    exchange are valued at the last sale price on the principal exchange where
    they are traded. Equity securities that have not traded on the date of
    valuation, or securities for which sale prices are not available, generally
    are valued using the mean between the last bid and asked prices. Short-term
    fixed income securities with remaining maturities of sixty days or less
    generally are valued at amortized cost. Shares of money market mutual funds
    are valued at such funds' net asset value.

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

    Securities or loan interests for which independent pricing services are
    unable to supply prices or for which market prices and/or quotations are not
    readily available or are considered to be unreliable are valued 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.

    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

38 Pioneer Long/Short Global Bond Fund | Annual Report | 8/31/14


    determination of the Fund's net asset value. Examples of a significant event
    might include political or economic news, corporate restructurings, natural
    disasters, terrorist activity or trading halts. Thus, the valuation of the
    Fund's securities may differ significantly from exchange prices and such
    differences could be material. 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.

    At August 31, 2014, no securities were valued using fair value methods
    (other than securities valued using prices supplied by independent pricing
    services).

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

    Dividend income is recorded on the ex-dividend date except that certain
    dividends from foreign securities where the ex-dividend date may have passed
    are recorded as soon as the Fund becomes aware of the ex-dividend data in
    the exercise of reasonable diligence. Interest income is recorded on the
    accrual basis.

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

B.  Foreign Currency Translation

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

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

                Pioneer Long/Short Global Bond Fund | Annual Report | 8/31/14 39


C.  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
    August 31, 2014 was $355,725. 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 appreciation or depreciation. 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. The use of futures
    contracts involves to varying degrees, element of market, interest rate,
    currency exchange rate and counterparty risks, which may exceed the amount
    recognized by the Fund. Changes in value of the contracts may not directly
    correlate to the changes in value of the underlying securities. The average
    value of contracts open during the period ended August 31, 2014 was
    $15,324,132.

    At August 31, 2014, open futures contracts were as follows:

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


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 5).

40 Pioneer Long/Short Global Bond Fund | Annual Report | 8/31/14


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 taxable income and net realized capital gains, if any, to its
    shareowners. Therefore, no federal income tax provision is required. As of
    August 31, 2014, 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.

    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
    August 31, 2014, the Fund reclassified $58,898 to decrease accumulated net
    investment loss, $32,953 to increase accumulated net realized loss on
    investments, foreign currency transactions, swap contracts and futures
    contracts and $25,945 to decrease paid-in capital to reflect permanent
    book/tax differences. These adjustments have no impact on the net assets or
    results of operations.

    At August 31, 2014, the Fund was permitted to carry forward $83,476 of
    long-term losses and $353,377 of short-term losses without limitation.

    There were no distributions paid during the fiscal year ended August 31,
    2014.

    The following shows the components of distributable earnings (losses) on a
    federal income tax basis at August 31, 2014:



    --------------------------------------------------------------------------
                                                                          2014
    --------------------------------------------------------------------------
                                                                  
    Distributable earnings:
    Undistributed ordinary income                                    $ 517,080
    Capital loss carryforward                                         (436,853)
    Unrealized appreciation                                             49,863
    --------------------------------------------------------------------------
         Total                                                       $ 130,090
    ==========================================================================


    The difference between book-basis and tax-basis net unrealized appreciation
    is attributable to the tax deferral of losses or wash sales, adjustments
    relating to catastrophe bonds and the mark to market of forward, swap and
    futures contracts.

                Pioneer Long/Short Global Bond Fund | Annual Report | 8/31/14 41


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 $194 in underwriting commissions on the sale of Class A shares during
    the period ended August 31, 2014.

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 transfer agent, Pioneer Investment Management Shareholder
    Services, Inc. (PIMSS), for its services are allocated among the classes of
    shares based on the number of accounts in each class and the ratable
    allocation of related out-of-pocket expenses (see Note 3).

    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

    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 underlying
    issues and their ability to meet their debt obligations. 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.

I.  Credit Default Swaption Writing

    The Fund may write put and covered call swaptions on portfolio securities in
    order to attempt to hedge against changes in the value of portfolio
    securities or to seek to increase total return. When a swaption 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 swaption.
    When the Fund writes an swaption, an amount equal to the premium received by
    the Fund is recorded

42 Pioneer Long/Short Global Bond Fund | Annual Report | 8/31/14


    as a liability and is subsequently adjusted to the current value of the
    swaption written. Premiums received from writing swaptions 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 gain, or, if the premium is less than the
    amount paid for the closing purchase transaction, as a realized loss. If a
    call swaption 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 a swaption bears the market risk of an
    unfavorable change in the price of the security underlying the written
    swaption.

    The average value of contracts open during the period ended August 31, 2014
    was $8,014.

    The Fund held one written swaption contract that was open at August 31,
    2014. If the swaption was exercised at August 31, 2014, the maximum amount
    the Fund would have been required to pay was $707. Written swaption
    contracts outstanding at period end are listed at the end of the Fund's
    schedule of investments.

    Transactions in written swaptions for the period ended August 31, 2014 are
    summarized as follows:



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

J.  Purchased Credit Default Swaptions

    The Fund may purchase put and call swaptions in order to attempt to hedge
    against changes in the value of portfolio securities or to seek to increase
    total return. Purchased call and put swaptions entitle the Fund to buy and
    sell a specified number of shares or units of a particular security,
    currency or index at a specified price at a specific date or within a
    specific period of time. Upon the purchase of a call or put swaption, the
    premium paid by the Fund is included in the Statement of Assets and
    Liabilities as an investment. All premiums are marked-to-market daily, and
    any unrealized gains or losses are recorded in the Fund's financial
    statements. As the purchaser of an index

                Pioneer Long/Short Global Bond Fund | Annual Report | 8/31/14 43


    swaption, the Fund has the right to receive a cash payment equal to any
    depreciation in the value of the index below the strike price of the
    swaption (in the case of a put) or equal to any appreciation in the value of
    the index over the strike price of the swaption (in the case of a call) as
    of the valuation date of the swaption. Premiums paid for purchased calls and
    put swaptions which have expired are treated as realized losses on
    investments in the Statement of Operations. Upon the exercise or closing of
    a purchased put swaption, the premium is offset against the proceeds on the
    sale of the underlying security or financial instrument in order to
    determine the realized gain or loss on investments. Upon the exercise or
    closing of a purchased call swaption, the premium is added to the cost of
    the security or financial instrument. The risk associated with purchasing
    swaptions is limited to the premium originally paid. The average value of
    contracts open during the period ended August 31, 2014 was $9,301. Purchased
    swaptions open at period end are listed at the end of the Fund's Schedule of
    Investments.

K.  Credit Default Swap Agreements

    A credit default swap is a contract between a buyer of protection and a
    seller of protection against a pre-defined credit event. The Fund may buy or
    sell credit default swap contracts to 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
    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.

44 Pioneer Long/Short Global Bond Fund | Annual Report | 8/31/14


    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.

    Open credit default swap contracts at August 31, 2014 are listed in the
    Schedule of Investments. The average value of swap contracts open during the
    period ended August 31, 2014 was $213,498.

L.  Interest Rate Swap Contracts

    The Fund may enter into interest rate swaps to attempt to hedge against
    interest rate fluctuations or to enhance its income. Pursuant to the
    interest rate swap agreement, the Fund negotiates with a counterparty to
    exchange a periodic stream of payments based on a benchmark interest rate.
    One cash flow stream will typically be a floating rate payment based upon
    the specified floating benchmark interest rate while the other is typically
    a fixed interest rate. Payment flows are usually netted against each other,
    with the difference being paid by one party to the other on a monthly basis.

    Periodic payments received or paid by the Fund are recorded as realized
    gains or losses in the Statement of Operations. Interest rate 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. Interest rate swap
    contracts are subject to counterparty risk and movements in interest rates.

    Open interest rate swap contracts at August 31, 2014 are listed in the
    Schedule of Investments. The average value of interest swap contracts open
    during the period ended August 31, 2014 was $25,155.

M.  Repurchase Agreements

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

2. Management Agreement

PIM, a wholly owned indirect subsidiary of UniCredit, manages the Fund's
portfolio. Management fees are calculated daily at an annual rate of 1.05% of
the average daily net assets of the Fund up to $1 billion and 0.95% of the
Fund's average daily net assets over $1 billion of the Fund. For the period
ending August 31, 2014, the effective management fee was equivalent to 1.05% of
the Fund's average daily net assets.

PIM has contractually agreed to limit ordinary operating expenses to the extent
required to reduce Fund expenses to 1.55%, 2.30% and 1.30% of the average daily
net assets attributable to Class A, Class C and Class Y shares, respectively.
These expense limitations are in effect through January 1, 2015. Fees waived and
expenses reimbursed during the period ended August 31, 2014 are reflected on the
Statement of Operations. Fees and expenses of other investment companies in
which the Fund may invest are not included in the expense limitations noted
above. 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 to affiliates" reflected on the Statement of Assets and Liabilities is
$24,305 in management fees, administrative costs and certain other
reimbursements payable to PIM at August 31, 2014.

3. Transfer Agent

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

In addition, the Fund reimburses PIMSS for out-of-pocket expenses incurred by
PIMSS related to shareholder communications activities such as proxy and
statement mailings, outgoing phone calls and omnibus relationship contracts. For
the period ended August 31, 2014, such out-of-pocket expenses by class of shares
were as follows:

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


Included in "Due to affiliates" reflected on the Statement of Assets and
Liabilities is $128 in transfer agent fees and out-of-pocket reimbursements
payable from PIMSS at August 31, 2014.

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 $1,155 in distribution fees payable to
PFD at August 31, 2014.

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 CDSC are paid to PFD. For the
period ended August 31, 2014, there were no CDSCs paid to PFD.

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 period ended August 31, 2014 was $16,213,471.

Report of Independent Registered Public Accounting Firm

To the Board of Trustees of Pioneer Series Trust V and the
Shareowners of Pioneer Long/Short Global Bond Fund:
--------------------------------------------------------------------------------

We have audited the accompanying statement of assets and liabilities of Pioneer
Long/Short Global Bond Fund (the "Fund"), one of the portfolios constituting
Pioneer Series Trust V, including the schedule of investments, as of August 31,
2014, and the related statements of operations and changes in net assets, and
the financial highlights for the period December 30, 2013 (commencement of
operations) through August 31, 2014. 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 audit.

We conducted our audit 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 audit 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 August 31, 2014, by correspondence with the custodian
and brokers and agent banks; where replies were not received from brokers and
agent banks, we performed other auditing procedures. We believe that our audit
provides 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 Long/Short Global Bond Fund as of August 31, 2014, and the results of
its operations, the changes in its net assets, and the financial highlights for
the period December 30, 2013, (commencement of operations) through August 31,
2014, in conformity with accounting principles generally accepted in the United
States of America.

President's Letter

Dear Shareowner,

As we move into the final few months of 2014, we remain confident that U.S.
economic growth remains sustainable, if moderately paced.  The weather-related
slowdown in the first quarter is behind us and labor market data continues to
show steady improvement. The number of people filing initial unemployment claims
is at the lowest level since the boom years of 2005-06, the number of job
openings is at the highest level since 2001, and unemployment is down to just
over 6%.  Barring an external shock, we think it is likely that the domestic
economic expansion will continue until the economy reaches full employment.
Until then, remaining labor market slack and moderate capacity utilization offer
the potential for continuing non-inflationary growth.

The global economic picture is somewhat less rosy, as the Russia/Ukraine
conflict is exacting a toll on the European economy, Japan is working through
the impact of a large tax increase, and the growth of China's investment-driven
economy is slowing. On balance, though, we expect the global economy to continue
to grow in the second half of 2014, further supporting the U.S. economy.

While our outlook is constructive, the risk of an adverse "external" shock, such
as a military conflict, remains. While many such risks may already be "priced
into" the market, we caution against complacency and believe investors should
always be prepared for possible market volatility.

At Pioneer, we have long advocated the benefits of staying diversified and
investing for the long term. And while diversification does not assure a profit
or protect against loss in a declining market, we believe there are still
opportunities for prudent investors to earn attractive returns.

2 Pioneer Long/Short Opportunistic Credit Fund | Annual Report | 8/31/14


On August 11, 2014, I joined Pioneer as the new President and CEO of Pioneer
Investment Management USA, Inc. Since 1928, Pioneer's investment professionals
have worked on behalf of our shareholders to find attractive investment
opportunities, incorporating our proprietary research and prudent risk
management techniques to construct our portfolios.

In my role, I will focus on preserving many of the rich qualities of our
history, while maintaining balance with the demands of this ever-changing world
in which we live.

We greatly appreciate your trust in us and we encourage you to seek investment
guidance and advice from your financial advisor to discuss your goals and
develop an overall investment plan or framework that addresses both your short-
and long-term goals.

Sincerely,

/s/ Lisa M. Jones

Portfolio Management Discussion | 8/31/14

In the following interview, portfolio managers Thomas Swaney and Benjamin Gord
discuss the factors that influenced Pioneer Long/Short Opportunistic Credit
Fund's performance for the abbreviated annual reporting period beginning with
the Fund's inception on December 30, 2013, and ending August 31, 2014, as well
as their investment approach in managing the Fund. Mr. Swaney, Head of
Alternative Fixed Income, U.S., a senior vice president, and a portfolio manager
at Pioneer (lead portfolio manager of the Fund since 2013), and Mr.  Gord, a
vice president and a portfolio manager at Pioneer, are responsible for the
day-to-day management of the Fund.

Q   Can you provide an overview of the Fund's approach?

A   The big picture is that we seek to have the Fund produce an average annual
    return that is greater than the return on 3-month Treasury bills, on an
    annualized basis, with volatility lower than one would experience in the
    broad equity market. In pursuing this goal, we seek to have the Fund provide
    positive returns over most trailing 12-month periods and to minimize the
    extent of any negative returns, regardless of market conditions.

    Obviously, if we are going to be successful in achieving our objective, the
    Fund's returns cannot be overly dependent on the direction of one or more
    financial asset categories. In seeking positive returns regardless of market
    conditions, we utilize two distinct strategies. One strategy is
    "directional," in that we need to be correct about whether a particular
    asset price is poised to go up or down. However, we seek to have the Fund's
    performance benefit from both positive and negative returns. This means that
    at times we invest the portfolio in some asset categories within the broad
    bond market by taking long positions, while speculating against other asset
    classes by taking short positions.

    The other part of the portfolio utilizes uncorrelated trading strategies, in
    which we do not have to take a stance on whether an individual market is
    going to rise or fall overall. Instead, we need to identify either a segment
    or security within a market that we believe will outperform versus another
    market segment or security. We execute these portfolio investment strategies
    across several different global financial markets and many different asset
    classes. We will seek to "pair" positions, meaning that the Fund will have a
    long position in one segment/security of a particular

4 Pioneer Long/Short Opportunistic Credit Fund | Annual Report | 8/31/14


    market, and a short position in another segment/security, such that the
    performance of the pair is not dependent on the direction of the market. We
    believe this strategy can allow the Fund to benefit from favorable relative
    performance, regardless of the overall direction of that market.

    Most importantly, we closely track the risks we have assumed in both
    portions of the portfolio and operate within an overall "risk budget," which
    is based on our goal of largely avoiding negative returns over a 12-month
    period.

Q   How did the Fund perform during the abbreviated annual reporting period from
    December 30, 2013, through August 31, 2014?

A   Pioneer Long/Short Opportunistic Credit Fund's Class A shares returned 1.10%
    at net asset value during the period between December 30, 2013, and August
    31, 2014. During the same period, the Fund's benchmark, the Bank of America
    Merrill Lynch (BofA ML) 3-Month U.S. Treasury-Bill Index, returned 0.03%.

Q   Can you review the principal portfolio investment strategies you implemented
    during the Fund's abbreviated annual reporting period ended August 31, 2014?
    How did those strategies help or hinder the Fund's performance?

A   We have implemented, to overall positive effect, a number of strategies
    within the "uncorrelated" portion of the Fund's portfolio. Our Currency
    Long/Short strategy has been a significant positive contributor to
    benchmark-relative return in the Fund's first eight months of operations.
    Specifically, we have taken long positions in the U.S. dollar while shorting
    the euro. That positioning has worked out well as the dollar has
    strengthened versus other major currencies. Also on the positive side, we
    implemented a number of curve trades in the portfolio's Credit Long/Short
    strategy, where the Fund is "long" in one part of an individual issuer's
    yield curve and short in another, depending on our outlook for the issuer's
    curve to steepen or flatten. We also had pair trades within this strategy
    utilizing two issuers within the same industry sector, for whom we expect
    performance to diverge. In addition, the Fund's portfolio holds a variety of
    event-linked (catastrophe) bonds, which are designed to pay reasonable
    yields in exchange for insurance protection against major calamities such as
    hurricanes, floods and earthquakes. We like catastrophe bonds for their low
    correlation to any equity or fixed-income market risks. That position
    contributed to the Fund's performance over the period.

        Pioneer Long/Short Opportunistic Credit Fund | Annual Report | 8/31/14 5


    On the downside, the Fund's Cross Asset Relative Value strategy was the
    leading detractor from performance during the abbreviated annual reporting
    period. Under the strategy, we seek to pair trades to take advantage of any
    distortions in relative valuation between asset classes: for instance,
    high-yield versus investment-grade corporates. The approach has experienced
    some challenges in the current environment of low volatility and narrow
    credit spreads, which are the differences in yield between various
    fixed-income securities with similar maturities. Our long/short trades
    related to equity and yield-curve exposures also modestly detracted from the
    Fund's performance during the period. With regard to the latter exposure, we
    have been shorting a very specific point on the U.S. yield curve, as we do
    not believe the markets are prepared for the likely pace of the Federal
    Reserve's (the Fed's) policy tightening should the domestic economy return
    to above-trend growth.

    Turning to the "directional" side of the portfolio, we have been wary of
    taking on long credit exposure given the spread tightening that has
    occurred. We have, however, held a portfolio position in euro-denominated
    bonds that are convertible into equity. That position gives the Fund
    exposure to any improvement in the European stock market over the next few
    years, along with downside protection. We have also taken positions in
    select U.S. convertible securities, in particular within the
    biotech/pharmaceutical area of the health care sector. More
    opportunistically, we have traded the portfolio in and out of high-yield
    issues in both the U.S. and Europe.

    The Fund has meaningful exposure to securitized credit markets, such as
    non-agency mortgages, where we see opportunities for the Fund to earn
    reasonable risk-adjusted returns with less sensitivity to the direction of
    the U.S. equity market. Because we seek to hedge out the accompanying
    interest-rate risk, we are isolating the cheapness of mortgage bonds.
    Another directional trade has been to take a long portfolio position in
    asset-sensitive financial companies, while extracting the equity beta from
    those positions using derivatives, along with a corresponding short
    position in large-cap industrial companies. (Beta is a statistical
    measurement of an investment's sensitivity to market movements in relation
    to an index.)

    On the short side of the directional portfolio, we took a position with
    respect to investment-grade debt in both Asia and Australia, which we viewed
    as being vulnerable to the credit slowdown in China. China is attempting to
    grow at a 7.5% rate while contracting credit and relying on a

6 Pioneer Long/Short Opportunistic Credit Fund | Annual Report | 8/31/14


    shadow banking system. We believed both the Asian and Australian credit
    markets were a prudent and efficient way to get the Fund some short exposure
    to a China policy error. We closed the trade during the period, with a
    modest negative impact on Fund performance.

Q   What is your assessment of the current macroeconomic climate and the
    investment opportunities it may present?

A   Overall, we expect global economic growth to continue to strengthen. In the
    U.S., we are looking for growth to move up into the range of historic
    long-term trends, supported by improvements in employment and the
    availability of credit. At the same time, we believe there will be
    disappointments along the way, and with the Fed no longer committed to
    stepping up its accommodative policies to backstop conditions, asset prices
    will likely experience significant volatility. Another macroeconomic
    development we are examining is the lack of a clear definition when it comes
    to emerging versus developed markets. Many emerging economies are actually
    in a better position from the standpoint of debt and current-account flows,
    and we anticipate that performance trends in global bond markets will become
    increasingly country-specific.

    More broadly, we would not be surprised to see market volatility and
    performance dispersion increase as global central bank policies diverge and
    as the Fed's tightening transitions from tapering quantitative easing to
    eventually raising interest rates. We believe that scenario could create
    opportunities for an uncorrelated investment strategy such as the Fund's,
    and we will seek to identify trades that can help it to capitalize on these
    emerging themes.

Fund securities.

        Pioneer Long/Short Opportunistic Credit Fund | Annual Report | 8/31/14 7


All investments are subject to risk, including the possible loss of principal.

The portfolio may invest in derivative securities, such as options, futures,
inverse floating-rate obligations, and swaps, among others, which can be
illiquid, may disproportionately increase losses, and have a potentially large
impact on the performance of the portfolio.

The Fund may take short positions, which involves leverage of its assets and
presents additional risks.

The Fund may invest in credit default swaps, which may in some cases be
illiquid, and they increase credit risk since the Fund has exposure to both the
issuer of the referenced obligation and the counterparty to the credit default
swap.

The Fund employs leverage, which increases the volatility of investment returns
and subjects the Fund to magnified losses.

Investments in fixed-income securities involve interest rate, credit, inflation,
and reinvestment risks.

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

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

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

8 Pioneer Long/Short Opportunistic Credit Fund | Annual Report | 8/31/14


The Fund may invest in event-linked bonds, on 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 Fund may invest in floating-rate loans; the value of collateral, if any,
securing a floating-rate loan can decline or may be insufficient to meet the
issuer's obligations or may be difficult to liquidate.

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 is non-diversified, which means that it can invest a large percentage
of its assets in the securities of any one or more issuers. This increases the
Fund's potential risk exposure.

These risks may increase share price volatility.

There is no assurance that these and other strategies used by the Fund will be
successful. Please see the prospectus for a more complete discussion of the
Fund's risks.

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.

Index Definitions
--------------------------------------------------------------------------------
The Bank of America Merrill Lynch (BofA ML) 3-month US Treasury Bill Index is
an unmanaged market index of U.S. Treasury securities maturing in 90 days, that

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.

*   The Fund commenced operations on December 30, 2013.

prospectus and financial statements for more information.

The net expense ratio reflects the contractual expense limitation currently in
effect through January 1, 2015, 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.

14 Pioneer Long/Short Opportunistic Credit Fund | Annual Report | 8/31/14


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 plus the
    expense ratio of the underlying funds. These combined totals were 1.88%,
    2.63% and 1.63% for Class A, Class C and Class Y shares, respectively. These
    combined ratios were multiplied by the average account value over the period
    multiplied by 184/365 (to reflect the partial year period).

Hypothetical Example for Comparison Purposes

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

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

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

*           Non-income producing security.

NR          Not rated by either S&P or Moody's.

(Cat Bond)  Catastrophe bond is a high-yield debt instrument that is
            usually insurance linked and meant to raise money in case of a
            catastrophe.

(Perpetual) Security with no stated maturity date.

REMICS      Real Estate Mortgage Investment Conduits.

(Step)      Step up bond issued with an initial coupon rate which converts to a
            higher rate at a later date.

(144A)      Security is exempt from registration under Rule 144A of the
            Securities Act of 1933. Such securities may be resold normally to
            qualified institutional buyers in a transaction exempt from

            amounted to $5,462,778 or 21.0% of total net assets.

**          Senior floating rate loan interests in which the Fund invests
            generally pay interest at rates that are periodically redetermined
            by reference to a base lending rate plus a premium. These base
            lending rates are generally (i) the lending rate offered by one or
            more major European banks, such as LIBOR (London InterBank Offered
            Rate), (ii) the prime rate offered by one or more major United
            States banks, (iii) the certificate of deposit or (iv) other base
            lending rates used by commercial lenders. The rate shown is the
            coupon rate at period end.

Various inputs are used in determining the value of the Fund's investments.
These inputs are summarized in the three broad levels listed below.

    Level 1 -- quoted prices in active markets for identical securities.

    Level 2 -- other significant observable inputs (including quoted prices for
               similar securities, interest rates, prepayment speeds, credit
               risk, etc.) See Notes to Financial Statements -- Note 1A.

    Level 3 -- significant unobservable inputs (including the Fund's own
               assumptions in determining fair value of investments) See Notes
               to Financial Statements -- Note 1A.

Generally, equity securities are categorized as Level 1, fixed income securities
and senior loans as Level 2 and securities valued using fair value methods
(other than prices supplied by independent pricing services or broker-dealers)
are categorized as Level 3. See Notes to Financial Statements -- Note 1A.

Notes to Financial Statements | 8/31/14

1. Organization and Significant Accounting Policies

Pioneer Long/Short Opportunistic Credit Fund (the Fund) is one of five
portfolios comprising Pioneer Series Trust V, a Delaware statutory trust. The
Fund is registered under the Investment Company Act of 1940 as a diversified,
open-end management investment company. The Fund's investment objective is to
seek total return.

The Fund offers three classes of shares designated as Class A, Class C and Class
Y shares. Class A, Class C and Class Y shares were first publicly offered on
December 31, 2013. 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 gains and losses on investments during the reporting
period. Actual results could differ from those estimates.

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

40 Pioneer Long/Short Opportunistic Credit Fund | Annual Report | 8/31/14


A.  Security Valuation

    Security transactions are recorded as of trade date. The net asset value of
    the Fund is computed once daily, on each day the New York Stock Exchange
    (NYSE) is open, as of the close of regular trading on the NYSE. Senior
    floating rate loan interests (senior loans) are valued in accordance with
    guidelines established by the Board of Trustees at the mean between the last
    available bid and asked prices from one or more brokers or dealers as
    obtained from Loan Pricing Corporation an independent pricing service. 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. Fixed income securities with
    remaining maturity of more than sixty days are valued at prices supplied by
    independent pricing services, which consider such factors as market prices,
    market events, quotations from one or more brokers, Treasury spreads,
    yields, maturities and ratings. Valuations may be supplemented by dealers
    and other sources, as required. Equity securities that have traded on an
    exchange are valued at the last sale price on the principal exchange where
    they are traded. Equity securities that have not traded on the date of
    valuation, or securities for which sale prices are not available, generally
    are valued using the mean between the last bid and asked prices. Short-term
    fixed income securities with remaining maturities of sixty days or less
    generally are valued at amortized cost. Shares of money market mutual funds
    are valued at such funds' net asset value.

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

    Securities or loan interests for which independent pricing services are
    unable to supply prices or for which market prices and/or quotations are not
    readily available or are considered to be unreliable are valued by a fair
    valuation team comprised of certain personnel of Pioneer Investment
    Management, Inc. (PIM), the Fund's investment advisor, 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. 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.

       Pioneer Long/Short Opportunistic Credit Fund | Annual Report | 8/31/14 41


    The Fund may use fair value methods if it is determined that a significant
    event has occurred after the close of the exchange or market on which the
    security trades and prior to the determination of the Fund's net asset
    value. Examples of a significant event might include political or economic
    news, corporate restructurings, natural disasters, terrorist activity or
    trading halts. Thus, the valuation of the Fund's securities may differ
    significantly from exchange prices and such differences could be material.
    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.

    At August 31, 2014, no securities were valued using fair value methods
    (other than securities valued using prices supplied by independent pricing
    services or broker-dealers).

    Principal amounts of mortgage-backed securities are adjusted for monthly
    paydowns. Premiums and discounts related to certain mortgage-backed
    securities are amortized or accreted in proportion to the monthly paydowns.
    All discounts/premiums on debt securities are accreted/amortized for finan-
    cial 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 is recorded on the
    accrual basis.

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

B.  Foreign Currency Translation

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

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

42 Pioneer Long/Short Opportunistic Credit Fund | Annual Report | 8/31/14


C.  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 August 31, 2014 was $449,996.  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. The use of futures
    contracts involves to varying degrees, element of market, interest rate,
    currency exchange rate and counterparty risks, which may exceed the amount
    recognized by the Fund. Changes in value of the contracts may not directly
    correlate to the changes in value of the underlying securities. The average
    value of contracts open during the period ended August 31, 2014 was
    $17,135,726.

    At August 31, 2014, open futures contracts were as follows:

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 5).

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 distrib-
    ute all of its taxable income and net realized capital gains, if any, to its
    shareowners. Therefore, no federal income tax provision is required. As of
    August 31, 2014, the Fund did not accrue any interest or penalties with
    respect to unrecognized 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 share-
    owners 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
    August 31, 2014, the Fund reclassified $590,127 to increase undistributed
    net investment income, $564,139 to increase accumulated net realized gain on
    investments, foreign currency transactions, swap contracts and futures
    contracts and $25,988 to decrease paid-in capital to reflect permanent
    book/tax differences. These adjustments have no impact on the net assets or
    results of operations.

    At August 31, 2014, the Fund was permitted to carry forward $501,757 of
    short-term losses and $149,967 of long-term losses without limitation.

    There were no distributions paid during the fiscal year ended August 31,
    2014.

    The following shows the components of distributable earnings (losses)
    on a federal income tax basis at August 31, 2014:



    ----------------------------------------------------------------------------
                                                                           2014
    ----------------------------------------------------------------------------
                                                                   
    Distributable earnings:
    Undistributed ordinary income                                      $820,428
    Capital loss carryforward                                         (651,754)
    Unrealized appreciation                                             104,744
    ----------------------------------------------------------------------------
    Total                                                              $273,418
    ============================================================================


    The difference between book-basis and tax-basis net unrealized appreciation
    is attributable to the tax deferral of the losses on wash sales, adjustments
    relating to catastrophe bonds and credit default swaps and the mark to
    market of forwards, swaps and future contracts.

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 $294 in underwriting commissions on the sale of Class A shares during
    the period ended August 31, 2014.

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 transfer agent, Pioneer Investment Management Shareholder
    Services, Inc. (PIMSS), for its services are allocated among the classes of
    shares based on the number of accounts in each class and the ratable
    allocation of related out-of-pocket expenses (see Note 3).

    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 invest-
    ment income dividends to Class A, Class C and Class Y shares can reflect
    different transfer agent and distribution expense rates.

H.  Risks

    Investing in foreign and/or emerging markets securities involves risks
    relating to interest rates, currency exchange rates and economic and
    political conditions. 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 prospectus contains unaudited information regarding the Fund's
    principal risks. Please refer to that document when considering the Fund's
    principal risks.

I.  Credit Default Swap Agreements

    A credit default swap is a contract between a buyer of protection and a
    seller of protection against a pre-defined credit event. The Fund may buy or
    sell credit default swap contracts to seek to increase the Fund's income, or
    to attempt to hedge the risk of default on Fund 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

       Pioneer Long/Short Opportunistic Credit Fund | Annual Report | 8/31/14 45


    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 up front payment to the protection seller in exchange for
    the rights to receive a contingent payment. An up front payment 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.

    Open credit default swap contracts at August 31, 2014 are listed in the
    Schedule of Investments. The average value of credit default swap contracts
    open during the period ended August 31, 2014 was $442,882.

46 Pioneer Long/Short Opportunistic Credit Fund | Annual Report | 8/31/14


J.  Interest Rate Swap Contracts

    The Fund may enter into interest rate swaps to attempt to hedge against
    interest rate fluctuations or to enhance its income. Pursuant to the
    interest rate swap agreement, the Fund negotiates with a counterparty to
    exchange a periodic stream of payments based on a benchmark interest rate.
    One cash flow stream will typically be a floating rate payment based upon
    the specified floating benchmark interest rate while the other is typically
    a fixed interest rate. Payment flows are usually netted against each other,
    with the difference being paid by one party to the other on a monthly basis.

    Periodic payments received or paid by the Fund are recorded as realized
    gains or losses in the Statement of Operations. Interest rate 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. Interest rate
    swap contracts are subject to counterparty risk and movements in interest
    rates.

    Open interest rate swap contracts at August 31, 2014 are listed in the
    Schedule of Investments. The average value of interest swap swap contracts
    open during the period ended August 31, 2014 was $25,808.

K.  Credit Default Swaption Writing

    The Fund may write put and covered call swaptions on portfolio securities in
    order to attempt to hedge against changes in the value of portfolio
    securities or to seek to increase total return. When a swaption 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 swaption.
    When the Fund writes an swaption, 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 swaption written. Premiums received from writing
    swaptions 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 gain, or, if the
    premium is less than the amount paid for the closing purchase transaction,
    as a realized loss. If a call swaption 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 a
    swaption bears the market risk of an unfavorable change in the price of the
    security underlying the written swaption.

    The average value of contracts open during the period ended August 31, 2014
    was $33,638. Written swaption contracts outstanding at period end are listed
    at the end of the Fund's schedule of investments.

       Pioneer Long/Short Opportunistic Credit Fund | Annual Report | 8/31/14 47


    The Fund held two written swaption contracts that were open at August 31,
    2014. If the swaptions were exercised at August 31, 2014, the maximum amount
    the Fund would have been required to pay was $19,436.

    Transactions in written swaptions for the period ended August 31, 2014 are
    summarized as follows:



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

    Options outstanding at end of period               (10,200,000)   $ 134,640
    ============================================================================


L.  Purchased Credit Default Swaptions

    The Fund may purchase put and call swaptions in order to attempt to hedge
    against changes in the value of portfolio securities or to seek to increase
    total return. Purchased call and put swaptions entitle the Fund to buy and
    sell a specified number of shares or units of a particular security,
    currency or index at a specified price at a specific date or within a
    specific period of time. Upon the purchase of a call or put swaption, the
    premium paid by the Fund is included in the Statement of Assets and
    Liabilities as an investment. All premiums are marked-to-market daily, and
    any unrealized gains or losses are recorded in the Fund's financial
    statements. As the purchaser of an index swaption, the Fund has the right to
    receive a cash payment equal to any depreciation in the value of the index
    below the strike price of the swaption (in the case of a put) or equal to
    any appreciation in the value of the index over the strike price of the
    swaption (in the case of a call) as of the valuation date of the swaption.
    Premiums paid for purchased calls and put swaptions which have expired are
    treated as realized losses on investments in the Statement of Operations.
    Upon the exercise or closing of a purchased put swaption, the premium is
    offset against the proceeds on the sale of the underlying security or
    financial instrument in order to determine the realized gain or loss on
    investments. Upon the exercise or closing of a purchased call swaption,
    the premium is added to the cost of the security or financial instrument.
    The risk associated with purchasing swaptions is limited to the premium
    originally paid. The average value of contracts open during the period ended
    August 31, 2014 was $33,853. Purchased swaptions open at period end are
    listed at the end of the Fund's Schedule of Investments.

2. Management Agreement

PIM, a wholly owned indirect subsidiary of UniCredit, manages the Fund's
portfolio. Management fees are calculated daily at an annual rate of 1.15%
of the average daily net assets of the Fund up to $1 billion and 1.05% of
the Fund's average daily net assets over $1 Billion. For the period ended
August 31, 2014, the annualized management fee was equivalent to 1.15% of
the Fund's average daily net assets.

PIM has contractually agreed to limit ordinary operating expenses to the
extent required to reduce Fund expenses to 1.70%, 2.45% and 1.45% of the
average daily net assets attributable to Class A, Class C and Class Y
shares, respectively. These expense limitations are in effect through
January 1, 2015. Fees waived and expenses reimbursed during the period
ended August 31, 2014 are reflected on the Statement of Operations. Fees
and expenses of other investment companies in which the Fund may invest are
not included in the expense limitations noted above. 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 to affiliates" reflected on the Statement of Assets and
Liabilities is $27,093 in management fees, administrative costs and certain
other reimbursements payable to PIM at August 31, 2014.

3. Transfer Agent

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

In addition, the Fund reimburses PIMSS for out-of-pocket expenses incurred by
PIMSS related to shareholder communications activities such as proxy and
statement mailings, outgoing phone calls and omnibus relationship contracts. For
the period ended August 31, 2014, such out-of-pocket expenses by class of shares
were as follows:

Included in "Due to affiliates" reflected on the Statement of Assets and
Liabilities is $22 in transfer agent fees and out-of-pocket reimbursements
payable to PIMSS at August 31, 2014.

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 $1,167 in distribution fees payable to
PFD at August 31, 2014.

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. Proceeds from the CDSCs are paid to PFD. For the period
ended August 31, 2014, no CDSCs were paid to PFD.

5. Forward Foreign Currency Contracts

At August 31, 2014, 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 period ended August 31, 2014 was $5,090,672.

       Pioneer Long/Short Opportunistic Credit Fund | Annual Report | 8/31/14 53


Report of Independent Registered Public Accounting Firm

To the Board of Trustees of Pioneer Series Trust V and the Shareowners of
Pioneer Long/Short Opportunistic Credit Fund:
--------------------------------------------------------------------------------

We have audited the accompanying statement of assets and liabilities of Pioneer
Long/Short Opportunistic Credit Fund (the "Fund"), one of the portfolios
constituting Pioneer Series Trust V, including the schedule of investments, as
of August 31, 2014, and the related statements of operations and changes in net
assets, and the financial highlights for the period December 30, 2013,
(commencement of operations) through August 31, 2014. 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 audit.

We conducted our audit 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 audit 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 August 31, 2014, by correspondence with the custodian,
brokers and agent banks; where replies were not received from brokers, we
performed other auditing procedures. We believe that our audit provides 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 Long/Short Opportunistic Credit Fund as of August 31, 2014, and the
results of its operations, the changes in its net assets, and the financial
highlights for the period December 30, 2013, (commencement of operations)
through August 31, 2014, in conformity with accounting principles generally
accepted in the United States of America.

 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.
