Consumer incomes, savings, wealth, and debt-servicing capacity have been solid buttresses for the recovering housing and auto industries. Industrial activity is growing only moderately, but current corporate profits are generally solid and balance sheets appear able to support needed capital spending and dividend* payouts. Tax hikes, spending restraint and a better economy have meaningfully cut the federal budget deficit. A modestly improving European economy and continuing economic improvement in Japan appear likely to result in improving global growth in 2014, further supporting the U.S. economy. In addition, we feel that continuing slack in labor markets and capacity utilization offer the potential for continuing growth without bottlenecks and rising inflation. After observing the strengthening economic trends, the Federal Reserve (the Fed) has begun scaling back its QE (quantitative easing) program, but short-term interest rates remain near zero, and while Fed Chair Janet Yellen has hinted that rates may be raised sooner than anticipated, market expectations are still focused on no earlier than 2015. There are certainly risks and uncertainties still facing the global economy as 2014 moves along. The European economy, while improving, remains weak, the Japanese economy faces a tax hike this spring, and a number of emerging market countries are experiencing difficulties. There are also geopolitical worries abroad, such as Russia's aggressive move against Ukraine, and more potential political fights at home, especially during a mid-term election year. While most of the widely recognized risks we have outlined may already be "priced into" the market, we believe investors should continue to expect 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. Our advice, as always, is to work closely with a trusted financial advisor to discuss your goals and work together to develop an investment strategy that meets your individual needs, keeping in mind that there is no single best strategy that works for every investor. * Dividends are not guaranteed. 2 Pioneer Global Equity Fund | Semiannual Report | 2/28/14 Pioneer's investment teams have, since 1928, sought out attractive opportunities in global equity and bond markets, using in-depth research to identify undervalued individual securities, and using thoughtful risk management to construct portfolios which seek to balance potential risks and rewards in an ever-changing world. We encourage you to learn more about Pioneer and our time-tested approach to investing by consulting with your financial advisor or visiting us online at us.pioneerinvestments.com. We greatly appreciate your trust in us, and we thank you for investing with Pioneer. Sincerely, /s/ Daniel K. Kingsbury Daniel K. Kingsbury President and CEO Pioneer Investment Management USA, Inc.

Pioneer Global Equity Fund | Semiannual Report | 2/28/14 3 Portfolio Management Discussion | 2/28/14 In the following interview, Marco Pirondini, Head of Equities, U.S., at Pioneer and a portfolio manager of Pioneer Global Equity Fund, discusses the factors that influenced the Fund's performance during the six-month period ended February, 28, 2014. Mr. Pirondini and David Glazer, a 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 six-month period ended February 28, 2014? A Pioneer Global Equity Fund's Class A shares returned 17.96% at net asset value during the six-month period ended February 28, 2014, while the Fund's benchmark, the Morgan Stanley Capital International (MSCI) World ND Index(1), returned 14.67%. During the same period, the average return of the 1,120 mutual funds in Morningstar's World Stock Funds category was 14.92%, and the average return of the 71 mutual funds in Lipper's Large Cap Core Fund category was 14.32%. Q How would you characterize the global equity markets during the six-month period ended February 24, 2014? A The past six months were initially characterized, back in September and October of 2013, by heightened political risk as the U.S. Congress and the Obama administration once again wrangled over budgetary matters, an impasse which resulted in a temporary government shutdown in October. In addition, the Federal Reserve's (the Fed's) initial communications during May of 2013 regarding the potential tapering of the U.S. central bank's monthly asset purchases (known as quantitative easing, or QE) were not well received by financial markets. Following the resolution of the U.S. budget crisis, however, additional signs that the pace of domestic economic growth was accelerating provided a very strong boost to equity markets, and U.S. stocks generally performed very well over the full six-month period. In addition, late in the fourth quarter of 2013, the Fed was able to more successfully articulate its strategy regarding both QE tapering and future interest-rate policy, and the announcement was well received by investors.

Additionally, bond prices for "peripheral" European countries displayed incremental recovery, providing a lift for those economies. Japan also benefited from the easing of monetary policy by the Bank of Japan, though Japanese stocks gave back some gains toward the end of the six-month period. The emerging markets continued to struggle, as many emerging economies wrestled with increasing interest rates and slowing economic growth. In addition, the QE tapering by the Fed, which translates into less "easy" money for investors to park in the emerging markets, had a negative effect on the emerging economies. 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 six-month period ended February 28, 2014? A During the period, the Fund was well positioned to take advantage of positive trends in the equity markets, and both our stock selection and sector allocation decisions aided performance. With regard to sector allocation, the Fund's performance strongly benefited from a large overweight to health care as well as from an overweight to international telecommunications stocks. A portfolio underweight to the emerging markets - especially to consumer stocks - also contributed to returns. * Diversification does not assure a profit nor protect against loss in a declining market. ** Dividends are not guaranteed. Pioneer Global Equity Fund | Semiannual Report | 2/28/14 5 As for individual stock selection, the Fund's position in the packaged drink distributor Green Mountain Coffee Roasters was the biggest contributor to performance during the six-month period. Investors reacted positively to the news that Green Mountain had entered into an agreement with Coca-Cola to add packaged soft drinks to the company's line of coffee products. In addition, the Fund's holdings in Vodafone aided returns as the British telecommunications company was able to sell its shares in Verizon Wireless back to Verizon at a large premium. The Fund's collection of currency- hedged Japanese investments also contributed to performance. Stock selections that did not fare well during the period included the Fund's exposure to Samsung, which detracted from returns. The company has not performed well despite its inexpensive valuation at the time we purchased it for the portfolio. Also, the Fund's position in Sumitomo, a Japanese bank, declined in value due to the market's perception that Japan's economy may be starting to slow down. Q What is your outlook? A We entered 2014 with expectations that the domestic economy would continue to grow, and at an increased pace. Though economic data releases in the first two months of the year have been less than robust, it is presumed that the slackened pace is mainly attributable to the very harsh winter weather conditions which prevailed in most of the United States. Outside of the U.S., two worrisome clouds for global economic growth have developed on the horizon. The first is the market's uncertainty over how well the emerging markets can deal with higher interest rates and the Fed's tapering of QE. The second is the possible negative influence the crisis in the Ukraine may have on the European economic recovery, given that Russia supplies 30% of the natural gas consumed in Europe. In spite of the Fed's withdrawal of QE - now well underway - the global economy continues to receive support from other central banks around the world, as many have retained monetary policies aimed at providing economic stimulus. Equity valuations, while no longer inexpensive, remain at average levels from a historical perspective. Given what we still view as a favorable investment environment for equities, we will continue to position the Fund's portfolio to take advantage of expected advances in global economic growth. 6 Pioneer Global Equity Fund | Semiannual Report | 2/28/14 Please refer to the Schedule of Investments on pages 16-23 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 portfolio may invest in derivative securities, which may include futures and options. These types of instruments can increase price fluctuation. At times, the Fund's investments may represent industries or industry sectors that are interrelated or have common risks, making it more susceptible to any economic, political, or regulatory developments or other risks affecting those industries and sectors. These risks may increase share price volatility. Past performance is no guarantee of future results, and there is no guarantee that market forecasts discussed will be realized. Any information in this shareholder report regarding market or economic trends or the factors influencing the Fund's historical or future performance are statements of opinion as of the date of this report.

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. Pioneer Global Equity Fund | Semiannual Report | 2/28/14 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 Paid on a $1,000 Investment in Pioneer Global Equity Fund Based on actual returns from September 1, 2013, through February 28, 2014. -------------------------------------------------------------------------------- Share Class A B C Y -------------------------------------------------------------------------------- Beginning Account $1,000.00 $1,000.00 $1,000.00 $1,000.00 Value on 9/1/13 -------------------------------------------------------------------------------- Ending Account $1,179.60 $1,174.60 $1,174.60 $1,182.20 Value on 2/28/14 -------------------------------------------------------------------------------- Expenses Paid $ 7.08 $ 11.92 $ 11.86 $ 4.38 During Period* -------------------------------------------------------------------------------- * Expenses are equal to the Fund's annualized net expense ratio plus the expense ratios of the underlying funds. These combined totals were 1.31%, 2.21%, 2.20% and 0.81% for Class A, Class B, Class C and Class Y shares, respectively. These combined ratios were multiplied by the average account value over the period, and then multiplied by 181/365 (to reflect the one-half year period) to calculate the "Expenses Paid During Period" in the table above. 14 Pioneer Global Equity Fund | Semiannual Report | 2/28/14 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 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. Expenses Paid on a $1,000 Investment in Pioneer Global Equity Fund Based on a hypothetical 5% return per year before expenses, reflecting the period from September 1, 2013, through February 28, 2014. -------------------------------------------------------------------------------- Share Class A B C Y -------------------------------------------------------------------------------- Beginning Account $1,000.00 $1,000.00 $1,000.00 $1,000.00 Value on 9/1/13 -------------------------------------------------------------------------------- Ending Account $1,018.30 $1,013.84 $1,013.88 $1,020.78 Value on 2/28/14 -------------------------------------------------------------------------------- Expenses Paid $ 6.56 $ 11.03 $ 10.99 $ 4.06 During Period* -------------------------------------------------------------------------------- * Expenses are equal to the Fund's annualized net expense ratio plus the expense ratios of the underlying funds. These combined totals were 1.31%, 2.21%, 2.20% and 0.81% for Class A, Class B, Class C and Class Y shares, respectively. These combined ratios were multiplied by the average account value over the period, and then multiplied by 181/365 (to reflect the one-half year period) to calculate the "Expenses Paid During Period" in the table above.

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 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. 32 Pioneer Global Equity Fund | Semiannual Report | 2/28/14 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 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 Committe 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 the Fund's investment advisor, is responsible for monitoring Pioneer Global Equity Fund | Semiannual Report | 2/28/14 33 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 February 24, 2013, no securities were valued using fair value methods (other than securities valued using prices supplied by independent pricing services). 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 February 28, 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. 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. The tax character of current year distributions payable will be determined at the end of the current taxable year. The tax character of distributions paid during the years ended August 31, 2013 was as follows: 34 Pioneer Global Equity Fund | Semiannual Report | 2/28/14 ---------------------------------------------------------------------------- 2013 ---------------------------------------------------------------------------- Distributions paid from: Ordinary income $2,291,138 ---------------------------------------------------------------------------- Total $2,291,138 ============================================================================ The following shows the components of distributable earnings on a federal income tax basis at August 31, 2013: ---------------------------------------------------------------------------- 2013 ---------------------------------------------------------------------------- Distributable earnings: Undistributed ordinary income $ 2,395,494 Capital loss carryforward (46,692,095) Net unrealized appreciation 12,704,683 ---------------------------------------------------------------------------- Total $ (31,591,918) ============================================================================ The difference between book-basis and tax-basis net unrealized appreciation is attributable to the tax deferral of losses on wash sales, the mark-to-market of foreign currency contracts and futures contracts and the 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 $5,223 in underwriting commissions on the sale of Class A shares during the six months ended February 28, 2014. 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 prices 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 Pioneer Global Equity Fund | Semiannual Report | 2/28/14 35 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 36 Pioneer Global Equity Fund | Semiannual Report | 2/28/14 deposited with the broker as collateral at February 28,2014 was $189,000. 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 six months ended February 28, 2014 was $2,271,276. At February 28, 2014, open futures contracts were as follows: ---------------------------------------------------------------------------- Number of Contracts Settlement Unrealized Type Long/(Short) Month Value Depreciation ---------------------------------------------------------------------------- F/C Japanese Yen Currency Future (60) 3/14 $(7,368,750) $(51,375) ---------------------------------------------------------------------------- Total $(51,375) ============================================================================ 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 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 Pioneer Global Equity Fund | Semiannual Report | 2/28/14 37 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 six months ended February 28, 2014 was $20,079. There were no purchased options outstanding at February 28, 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 six months ended February 28, 2014 was $111,930. Written call option contracts outstanding at period end are listed at the end of the Fund's schedule of investments. The Fund held 1 written call option contract that was open at February 28, 2014. If the put options were exercised at February 28, 2014, the maximum amount the Fund would have been required to pay was $11,200. Transactions in written call options for the six months ended February 28, 2014 are summarized as follows: ---------------------------------------------------------------------------- Number of Contracts Premium Received ---------------------------------------------------------------------------- Options open at beginning of period -- $ -- Options opened (1,120) (444,918) Options exercised 560 123,533 Options closed 480 293,454 Options expired 70 14,961 ---------------------------------------------------------------------------- Options open at end of period (10) $ (12,970) ============================================================================ 38 Pioneer Global Equity Fund | Semiannual Report | 2/28/14 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 six months ended February 28, 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. 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 six months ended February 28, 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 $12,154 in management fees, administrative costs and certain other reimbursements payable to PIM at February 28, 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 six months ended February 28, 2014, such out-of-pocket expenses by class of shares were as follows: -------------------------------------------------------------------------------- Shareholder Communications: -------------------------------------------------------------------------------- Class A $33,778 Class B 2,231 Class C 4,915 Class Y 497 -------------------------------------------------------------------------------- Total: $41,421 ================================================================================ Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $23,698 in transfer agent fees and out-of-pocket reimbursements payable to PIMSS at February 28, 2014. Pioneer Global Equity Fund | Semiannual Report | 2/28/14 39 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 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 $1,557 in distribution fees payable to PFD at February 28, 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 six months ended February 28, 2014, CDSCs in the amount of $2,835 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 six months ended February 28, 2014, the Fund's expenses were not reduced under such arrangements. 6. Forward Foreign Currency Contracts At February 28, 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 six months ended February 28, 2014 was $9,802,800. 40 Pioneer Global Equity Fund | Semiannual Report | 2/28/14 Open forward foreign currency contracts at February 28, 2014 were as follows: --------------------------------------------------------------------------------------------- Net Net In Unrealized Contracts Exchange Settlement Appreciation Currency to Deliver For Date Value (Depreciation) --------------------------------------------------------------------------------------------- CHF (Swiss Franc) (79,524) $ (90,472) 3/5/14 $ (90,518) $ (46) GBP (British Pound Sterling) (95,315) (159,748) 3/5/14 (159,734) 14 SGD (Singapore Dollar) (11,826) (9,328) 3/5/14 (9,329) (1) --------------------------------------------------------------------------------------------- Total $ (33) ============================================================================================= 7.

(PIM) serves as the investment adviser to Pioneer Global Equity Fund (the Fund) pursuant to an investment advisory agreement between PIM and the Fund. In order for PIM to remain the investment adviser of the Fund, the Trustees of the Fund must determine annually whether to renew the investment advisory agreement for the Fund. The contract review process began in March 2013 as the Trustees of the Fund agreed on, among other things, an overall approach and timeline for the process. In July 2013, the Trustees approved the format of the contract review materials and submitted their formal request to PIM to furnish information necessary to evaluate the terms of the investment advisory agreement. The contract review materials were provided to the Trustees in July 2013 and September 2013. After reviewing and discussing the materials, the Trustees submitted a request for additional information to PIM, and materials were provided in response to this request. Meetings of the Independent Trustees of the Fund were held in July, September, and November, 2013 to review and discuss the contract review materials. In addition, the Trustees took into account the information related to the Fund provided to the Trustees at regularly scheduled meetings. At a meeting held on November 12, 2013, based on their evaluation of the information provided by PIM and third parties, the Trustees of the Fund, including the Independent Trustees voting separately, unanimously approved the renewal of the investment advisory agreement for another year. In considering the renewal of the investment advisory agreement, the Trustees considered various factors that they determined were relevant, including the factors described below. In all quintile rankings referred to throughout this disclosure, first quintile is most favorable to the Fund's shareowners. Thus, highest relative performance would be first quintile and lowest relative expenses would also be first quintile. The Trustees did not identify any single factor as the controlling factor in determining to approve the renewal of the agreement. Nature, Extent and Quality of Services The Trustees considered the nature, extent and quality of the services that had been provided by PIM to the Fund, taking into account the investment objective and strategy of the Fund. The Trustees reviewed the terms of the investment advisory agreement. The Trustees also reviewed PIM's investment approach for the Fund and its research process. The Trustees considered the resources of PIM and the personnel of PIM who provide investment management services to the Fund. They also reviewed the amount of non-Fund assets managed by the portfolio managers of the Fund. The Trustees considered the non-investment resources and personnel of PIM involved in 44 Pioneer Global Equity Fund | Semiannual Report | 2/28/14 PIM's services to the Fund, including PIM's compliance and legal resources and personnel. The Trustees noted the substantial attention and high priority given by PIM's senior management to the Pioneer fund complex. The Trustees considered that PIM supervises and monitors the performance of the Fund's service providers and provides the Fund with personnel (including Fund officers) and other resources that are necessary for the Fund's business management and operations. The Trustees also considered that, as administrator, PIM is responsible for the administration of the Fund's business and other affairs. The Trustees considered the fees paid to PIM for the provision of administration services. Based on these considerations, the Trustees concluded that the nature, extent and quality of services that had been provided by PIM to the Fund were satisfactory and consistent with the terms of the investment advisory agreement. Performance of the Fund The Trustees review the Fund's performance on a regular basis, based on analysis and data prepared by PIM for this purpose and discuss performance issues with PIM on an ongoing basis. For purposes of their contract renewal deliberations, the Trustees considered the performance results of the Fund over various time periods. They reviewed information comparing the Fund's performance with the performance of its peer group of funds as classified by Morningstar, Inc. (Morningstar), an independent provider of investment company data, and with the performance of the Fund's benchmark index. The Trustees considered that the Fund's annualized total return was in the second quintile of its Morningstar category for the one year period ended June 30, 2013, in the fourth quintile of its Morningstar category for the three year period ended June 30, 2013, and in the fifth quintile of its Morningstar category for the five year period ended June 30, 2013. The Trustees noted the discussions held throughout the year regarding the Fund's performance and confirmed that those discussions were factored into the Trustees' deliberations concerning the renewal of the advisory agreement. They indicated that they were satisfied with the discussions with PIM with respect to the Fund's performance. Management Fee and Expenses The Trustees considered information showing the fees and expenses of the Fund in comparison to the management fees and expense ratios of its peer group of funds as classified by Morningstar and also to the expense ratios of a peer group of funds selected on the basis of criteria determined by the Independent Trustees for this purpose using data provided by Strategic Insight Mutual Fund Research and Consulting, LLC (Strategic Insight), an independent third party. Pioneer Global Equity Fund | Semiannual Report | 2/28/14 45 The Trustees considered that the Fund's management fee for the twelve months ended June 30, 2013 was in the second quintile relative to the management fees paid by other funds in its Morningstar peer group for the comparable period. The Trustees also considered the breakpoints in the management fee schedule and the reduced fee rates above certain asset levels. The Trustees considered that the expense ratio of the Fund's Class A shares for the twelve months ended June 30, 2013 was in the second quintile relative to its Morningstar peer group and in the first quintile relative to its Strategic Insight peer group, in each case for the comparable period. The Trustees also considered that the expense ratio of the Fund's Class Y shares for the twelve months ended June 30, 2013 was in the first quintile relative to both its Morningstar peer group and its Strategic Insight peer group, in each case for the comparable period. The Trustees noted that PIM was waiving fees and/or reimbursing expenses in order to limit the ordinary operating expenses of the Fund. The Trustees reviewed management fees charged by PIM and PIM's affiliate, Pioneer Institutional Asset Management, Inc. (together with PIM, "Pioneer") to institutional and other clients, including publicly offered European funds sponsored by affiliates of Pioneer, unaffiliated U.S. registered investment companies (in a sub-advisory capacity), and unaffiliated foreign and domestic separate accounts. The Trustees also considered PIM's costs in providing services to the Fund and Pioneer's costs in providing services to the other clients and considered the differences in management fees and profit margins for Fund and non-Fund services. In evaluating the fees associated with Pioneer's client accounts, the Trustees took into account the respective demands, resources and complexity associated with the Fund and client accounts. The Trustees noted that, in some instances, the fee rates for those clients were lower than the management fee for the Fund and considered that, under the investment advisory agreement with the Fund, PIM performs additional services for the Fund that it does not provide to those other clients or services that are broader in scope, including oversight of the Fund's other service providers and activities related to compliance and the extensive regulatory and tax regimes to which the Fund is subject. The Trustees also considered the different entrepreneurial risks associated with PIM's management of the Fund and Pioneer's management of the other client accounts. The Trustees concluded that the management fee payable by the Fund to PIM was reasonable in relation to the nature and quality of the services provided by PIM. Profitability The Trustees considered information provided by PIM regarding the profitability of PIM with respect to the advisory services provided by PIM to the Fund, including the methodology used by PIM in allocating certain of its costs to the management of the Fund. The Trustees also considered PIM's 46 Pioneer Global Equity Fund | Semiannual Report | 2/28/14 profit margin in connection with the overall operation of the Fund. They further reviewed the financial results realized by PIM and its affiliates from non-fund businesses. The Trustees considered PIM's profit margins with respect to the Fund in comparison to the limited industry data available and noted that the profitability of any adviser was affected by numerous factors, including its organizational structure and method for allocating expenses. The Trustees concluded that PIM's profitability with respect to the management of the Fund was not unreasonable. Economies of Scale The Trustees considered PIM's views relating to economies of scale in connection with the Pioneer Funds as fund assets grow and the extent to which any such economies of scale are shared with funds and fund shareholders. The Trustees noted the breakpoints in the management fee schedule. The Trustees recognize that economies of scale are difficult to identify and quantify, rarely identifiable on a fund-by-fund basis, and that, among other factors that may be relevant, are the following: fee levels, expense subsidization, investment by PIM in research and analytical capabilities and PIM's commitment and resource allocation to the Fund. The Trustees noted that profitability also may be an indicator of the availability of any economies of scale, although profitability may vary for other reasons particularly, for example during the recent difficult periods for financial markets, as the level of services was maintained notwithstanding a significant decline in PIM's fee revenues from the Fund. Accordingly, the Trustees concluded that economies of scale, if any, were being appropriately shared with the Fund. Other Benefits The Trustees considered the other benefits to PIM from its relationship with the Fund. The Trustees considered the character and amount of fees paid by the Fund, other than under the investment advisory agreement, for services provided by PIM and its affiliates. The Trustees further considered the revenues and profitability of PIM's businesses other than the fund business. The Trustees considered the intangible benefits to PIM by virtue of its relationship with the Fund and the other Pioneer funds. The Trustees concluded that the receipt of these benefits was reasonable in the context of the overall relationship between PIM and the Fund. Conclusion After consideration of the factors described above as well as other factors, the Trustees, including all of the Independent Trustees, concluded that the investment advisory agreement between PIM and the Fund, including the fees payable thereunder, was fair and reasonable and voted to approve the proposed renewal of the investment advisory agreement for the Fund.

Consumer incomes, savings, wealth, and debt-servicing capacity have been solid buttresses for the recovering housing and auto industries. Industrial activity is growing only moderately, but current corporate profits are generally solid and balance sheets appear able to support needed capital spending and dividend* payouts. Tax hikes, spending restraint and a better economy have meaningfully cut the federal budget deficit. A modestly improving European economy and continuing economic improvement in Japan appear likely to result in improving global growth in 2014, further supporting the U.S. economy. In addition, we feel that continuing slack in labor markets and capacity utilization offer the potential for continuing growth without bottlenecks and rising inflation. After observing the strengthening economic trends, the Federal Reserve (the Fed) has begun scaling back its QE (quantitative easing) program, but short-term interest rates remain near zero, and while Fed Chair Janet Yellen has hinted that rates may be raised sooner than anticipated, market expectations are still focused on no earlier than 2015. There are certainly risks and uncertainties still facing the global economy as 2014 moves along. The European economy, while improving, remains weak, the Japanese economy faces a tax hike this spring, and a number of emerging market countries are experiencing difficulties. There are also geopolitical worries abroad, such as Russia's aggressive move against Ukraine, and more potential political fights at home, especially during a mid-term election year. While most of the widely recognized risks we have outlined may already be "priced into" the market, we believe investors should continue to expect 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. Our advice, as always, is to work closely with a trusted financial advisor to discuss your goals and work together to develop an investment strategy that meets your individual needs, keeping in mind that there is no single best strategy that works for every investor. * Dividends are not guaranteed. 2 Pioneer High Income Municipal Fund | Semiannual Report | 2/28/14 Pioneer's investment teams have, since 1928, sought out attractive opportunities in global equity and bond markets, using in-depth research to identify undervalued individual securities, and using thoughtful risk management to construct portfolios which seek to balance potential risks and rewards in an ever-changing world.

Pioneer High Income Municipal Fund | Semiannual Report | 2/28/14 3 Portfolio Management Discussion | 2/28/14 Tax-exempt municipal bonds -- led by higher-yielding municipal issues -- began recovering their value during the first two months of 2014 after remaining out of favor with investors during the final four months of 2013. The change in market sentiment occurred as investors were drawn by the low prices and competitive yields offered by municipal bonds. In the following interview, David Eurkus and Jonathan Chirunga discuss the factors that influenced the performance of Pioneer High Income Municipal Fund over the six-month period ended February 28, 2014. Mr. Eurkus, 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 six-month period ended February 28, 2014? A Pioneer High Income Municipal Fund's Class A shares returned 2.13% at net asset value during the six-month period ended February 28, 2014, while the Fund's benchmark, the Barclays High Yield Municipal Bond Index (the Barclays Index), returned 8.39%. During the same period, the average return of the 180 mutual funds in Morningstar's High Yield Municipal Funds category was 7.07%, and the average return of the 137 mutual funds in Lipper's High Yield Municipal Debt Funds category was 7.21%. Q How would you describe the investment environment for high-yield municipal bonds during the six-month period ended February 28, 2014? A It was a period during which investor attitudes about municipal bonds changed dramatically, moving from deeply negative to highly positive. The six-month period began with municipal bonds, including lower-rated securities with higher yields, performing poorly, as they had since the spring of 2013 when a succession of events undermined their standing among fixed-income investors. Some of the events occurred prior to the start of the six-month period, but their effects were felt for several months. First, in May 2013, then-Federal Reserve (Fed) Chairman Ben Bernanke suggested that the Fed might begin tapering back the pace of its accommodative quantitative easing (QE) program, which had been an important part of the Fed's monetary policies aimed at keeping interest rates low and stimulating economic growth. The prospect that the Fed might begin tapering QE affected bond investments in general and had a collateral effect on the municipal market. The municipal market then took a second hit when the City of Detroit filed for bankruptcy protection during the mid-summer of 2013. The tarnishing effects of the Detroit announcement were compounded later in the summer when media coverage of the debt 4 Pioneer High Income Municipal Fund | Semiannual Report | 2/28/14 problems plaguing the Commonwealth of Puerto Rico stirred more concerns among investors. As the concerns grew widespread, each of the three major bond rating agencies lowered its credit ratings of Puerto Rican bonds. The cumulative effect of the negative news stories was to undermine the reputation of municipal bonds in general, especially lower-rated, higher-yielding municipals that carried more credit risk than higher-rated securities. In that environment, municipal bond prices continued to fall and their yields rose during the first four months of the six-month period, which encompassed the final four months of 2013. During that period, higher-yielding municipals underperformed investment-grade municipals. The sell-off in municipal bonds continued into the first week of 2014, before market sentiment abruptly changed and municipal bond prices started snapping back, a rally led by high-yield municipal debt. The primary factor in the market rally was the growing recognition among investors that municipal bond prices had fallen to historically low levels and thus the asset class was offering extremely attractive prices and yields as compared with other types of fixed-income investments, including taxable bonds. Non-traditional investors, including property-and-casualty insurers and other financial institutions, began buying up municipal bonds. The increased buying activity came as financial institutions published their calendars of expected new bond issuance, indicating that the number of new municipal bonds issued in 2014 could be as much as 20% lower than the amount issued during 2013. The imbalance caused by increasing demand and decreasing supply led to a brisk rally in municipal bond prices during January and February 2014, with high-yield municipals benefiting the most. The rally was sustained by a supportive economic backdrop featuring slow growth and relatively tame inflation numbers. As investors moved back into the high-yield municipal market, even the now-downgraded bonds issued by the Commonwealth of Puerto Rico saw new demand. Q What were the main reasons for the Fund's underperformance of the benchmark Barclays Index during the six-month period ended February 28, 2014? A A significant factor in the Fund's underperformance relative to the Barclays Index during the period was the somewhat high exposure in the portfolio to bonds backed by continuing care retirement community (CCRC) projects, as CCRCs were one of the weaker-performing segments of the high-yield municipal market. We reduced the Fund's holdings of CCRCs, significantly, by the end of the six-month period. Nevertheless, the Fund's earlier, somewhat heavy exposure to CCRCs proved to be a drag on benchmark-relative results. In addition, the portfolio owned some other disappointing investments which weighed on the Fund's relative results. Holdings that underperformed during the period included industrial development revenue bonds used to finance the Galvstar steel processing Pioneer High Income Municipal Fund | Semiannual Report | 2/28/14 5 plant in Erie County, N.Y. All in all during the period, we continued our transition of the portfolio, moving to increase the diversification* of the Fund's investments while reducing allocations to other areas of the market in order to avoid overexposures to any one sector. While the Fund underperformed the overall market during the period, there were some bright spots, as we were able to add some investments that quickly exerted positive effects on the Fund's results. Investments where performance was notably strong during the period included a group of securities backed by charter schools located throughout the nation, including those in California, Pennsylvania, Texas and Colorado. It is worth noting that the Fund had no direct investments in either City of Detroit or Commonwealth of Puerto Rico bonds during the six-month period. Q What is your investment outlook? A We have a positive outlook for municipal securities, and especially high- yield municipals. The supply of new municipal securities has shrunk from the levels of the previous two years, while market demand is rising. Traditional investors attracted by the tax advantages of municipal securities are being joined by non-traditional investors who see attractive values in the tax-exempt market, especially relative to the taxable bond market. Even though the Fed has recently hinted that interest rates may rise sooner than originally expected, the timetable is uncertain and current rates remain historically low, making the higher yields offered by municipal bonds appear compelling at the present time. The favorable supply-demand dynamics in the municipal market are providing a good backdrop for our efforts to restructure the Fund's portfolio, adding more diversification while focusing on investments in securities with strong investment fundamentals. Our security analysts continue to scrutinize each portfolio holding while also looking for opportunities to add more variety. We intend, for example, to reduce further the Fund's exposure to CCRCs from the current 35% level to between roughly 20% and 25% of net assets. As we do this, our credit analysts will continue searching for newer potential investments backed by projects supported by reliable revenue sources. We expect to continue to focus the Fund's investments principally on project revenue bonds, which are securities backed by the revenue streams produced by specific public projects. Over the longer term, we believe project-specific investments should continue to be more reliable than other municipal bonds backed by general municipal revenues (known as general obligation bonds). Among the sectors of the municipal market in which we * Diversification does not assure a profit nor protect against loss in a declining market. 6 Pioneer High Income Municipal Fund | Semiannual Report | 2/28/14 are looking for opportunities are bonds backed by revenues generated by charter schools, transportation projects, tobacco-settlement lawsuits, and industrial development projects. Please refer to the Schedule of Investments on pages 15-22 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 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 inverse floating-rate obligations (a type of derivative instrument), which may have price volatility and involve leverage risk. 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. Past performance is not a guarantee of future results, and there is no guarantee that market forecasts discussed will be realized.

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 Paid on a $1,000 Investment in Pioneer High Income Municipal Fund Based on actual returns from September 1, 2013, through February 28, 2014. -------------------------------------------------------------------------------- Share Class A C Y -------------------------------------------------------------------------------- Beginning Account $1,000.00 $1,000.00 $1,000.00 Value on 9/1/13 -------------------------------------------------------------------------------- Ending Account Value $1,021.30 $1,017.40 $1,021.90 (after expenses) on 2/28/14 -------------------------------------------------------------------------------- Expenses Paid $ 4.36 $ 8.20 $ 3.56 During Period* -------------------------------------------------------------------------------- * Expenses are equal to the Fund's annualized net expense ratio of 0.87%, 1.64% and 0.71% for Class A, Class C and Class Y shares, respectively, multiplied by the average account value over the period multiplied by 181/365 (to reflect the one-half year period). Pioneer High Income Municipal Fund | Semiannual Report | 2/28/14 13 Hypothetical Example for Comparison Purposes The table below provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the tables are meant to highlight your ongoing costs only and do not reflect any transaction costs, such as sales charges (loads) that are charged at the time of the transaction.

The accompanying notes are an integral part of these financial statements. Pioneer High Income Municipal Fund | Semiannual Report | 2/28/14 29 Notes to Financial Statements | 2/28/14 (unaudited) 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: 30 Pioneer High Income Municipal Fund | Semiannual Report | 2/28/14 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. 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 February 28, 2014, there were no securities that were valued using fair value methods (other than securities valued using prices supplied by independent pricing services). 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. Pioneer High Income Municipal Fund | Semiannual Report | 2/28/14 31 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 February 28, 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. The tax character of current year distributions payable will be determined at the end of the current taxable year. The tax character of distributions paid during the year ended August 31, 2013 was as follows: --------------------------------------------------------------------------- 2013 --------------------------------------------------------------------------- Distributions paid from: Tax-exempt income $40,383,212 Ordinary income 2,210,747 --------------------------------------------------------------------------- Total $42,593,959 =========================================================================== The following shows the components of distributable earnings on a federal income tax-basis at August 31, 2013: --------------------------------------------------------------------------- 2013 --------------------------------------------------------------------------- Distributable earnings: Undistributed tax-exempt income $ 9,472,465 Capital loss carryforward (55,821,101) Dividend payable (731,789) Net unrealized depreciation (8,760,395) --------------------------------------------------------------------------- Total $ (55,840,820) =========================================================================== 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. 32 Pioneer High Income Municipal Fund | Semiannual Report | 2/28/14 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 $23,205 in underwriting commissions on the sale of Class A shares during the six months ended February 28, 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. During the six months ended February 28, 2014, the Fund recognized gains of $2,580 in settlement of class action lawsuits from one company, as reflected on the Statement of Operations. Distribution fees are calculated based on the average daily net asset value attributable to Class A and Class C shares of the Fund, respectively (see Note 4). Class Y shares do not pay distribution fees. All expenses and fees paid to the transfer agent, Pioneer Investment Management Shareholder Services, Inc. (PIMSS), for its services are allocated among the classes of shares based on the number of accounts in each class and the ratable allocation of related out-of-pocket expenses (see Note 3). The Fund declares, as daily dividends, substantially all of its net investment income. All dividends are paid on a monthly basis. Short-term capital gain distributions, if any, may be declared with the daily dividends. Distributions to shareowners are recorded as of the ex-dividend date. Distributions paid by the Fund with respect to each class of shares are calculated in the same manner and at the same time, except that net investment income dividends to Class A, Class C, and Class Y shares can reflect different transfer agent and distribution expense rates. 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 Pioneer High Income Municipal Fund | Semiannual Report | 2/28/14 33 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 six months ended February 28, 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 $18,422 in management fees, administrative costs and certain other reimbursements payable to PIM at February 28, 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 six months ended February 28, 2014, such out-of-pocket expenses by class of shares were as follows: -------------------------------------------------------------------------------- Shareholder Communications: -------------------------------------------------------------------------------- Class A $ 41,658 Class C 52,007 Class Y 70,193 -------------------------------------------------------------------------------- Total $163,858 ================================================================================ Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $75,844 in transfer agent fees and out-of-pocket reimbursements payable to PIMSS at February 28, 2014. 34 Pioneer High Income Municipal Fund | Semiannual Report | 2/28/14 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 $11,698 in distribution fees payable to PFD at February 28, 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 six months ended February 28, 2014, CDSCs in the amount of $36,083 were paid to PFD. 5. Expense Offset Arrangements The Fund has entered into certain expense offset arrangements with PIMSS which may result in a reduction in the Fund's total expenses due to interest earned on cash held by PIMSS. For the six months ended February 28, 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 Pioneer High Income Municipal Fund | Semiannual Report | 2/28/14 35 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. For the six months ended February 28, 2014, the Fund had no borrowings under the credit agreement. 36 Pioneer High Income Municipal Fund | Semiannual Report | 2/28/14 Approval of Investment Advisory Agreement Pioneer Investment Management, Inc. (PIM) serves as the investment adviser to Pioneer High Income Municipal Fund (the Fund) pursuant to an investment advisory agreement between PIM and the Fund. In order for PIM to remain the investment adviser of the Fund, the Trustees of the Fund must determine annually whether to renew the investment advisory agreement for the Fund. The contract review process began in March 2013 as the Trustees of the Fund agreed on, among other things, an overall approach and timeline for the process. In July 2013, the Trustees approved the format of the contract review materials and submitted their formal request to PIM to furnish information necessary to evaluate the terms of the investment advisory agreement. The contract review materials were provided to the Trustees in July 2013 and September 2013. After reviewing and discussing the materials, the Trustees submitted a request for additional information to PIM, and materials were provided in response to this request. Meetings of the Independent Trustees of the Fund were held in July, September, and November, 2013 to review and discuss the contract review materials. In addition, the Trustees took into account the information related to the Fund provided to the Trustees at regularly scheduled meetings. At a meeting held on November 12, 2013, based on their evaluation of the information provided by PIM and third parties, the Trustees of the Fund, including the Independent Trustees voting separately, unanimously approved the renewal of the investment advisory agreement for another year. In considering the renewal of the investment advisory agreement, the Trustees considered various factors that they determined were relevant, including the factors described below. In all quintile rankings referred to throughout this disclosure, first quintile is most favorable to the Fund's shareowners. Thus, highest relative performance would be first quintile and lowest relative expenses would also be first quintile. The Trustees did not identify any single factor as the controlling factor in determining to approve the renewal of the agreement. Nature, Extent and Quality of Services The Trustees considered the nature, extent and quality of the services that had been provided by PIM to the Fund, taking into account the investment objective and strategy of the Fund. The Trustees reviewed the terms of the investment advisory agreement. The Trustees also reviewed PIM's investment approach for the Fund and its research process. The Trustees considered the resources of PIM and the personnel of PIM who provide investment Pioneer High Income Municipal Fund | Semiannual Report | 2/28/14 37 management services to the Fund. They also reviewed the amount of non-Fund assets managed by the portfolio managers of the Fund. The Trustees considered the non-investment resources and personnel of PIM involved in PIM's services to the Fund, including PIM's compliance and legal resources and personnel. The Trustees noted the substantial attention and high priority given by PIM's senior management to the Pioneer fund complex. The Trustees considered that PIM supervises and monitors the performance of the Fund's service providers and provides the Fund with personnel (including Fund officers) and other resources that are necessary for the Fund's business management and operations. The Trustees also considered that, as administrator, PIM is responsible for the administration of the Fund's business and other affairs. The Trustees considered the fees paid to PIM for the provision of administration services. Based on these considerations, the Trustees concluded that the nature, extent and quality of services that had been provided by PIM to the Fund were satisfactory and consistent with the terms of the investment advisory agreement. Performance of the Fund The Trustees review the Fund's performance on a regular basis, based on analysis and data prepared by PIM for this purpose and discuss performance issues with PIM on an ongoing basis. For purposes of their contract renewal deliberations, the Trustees considered the performance results of the Fund over various time periods. They reviewed information comparing the Fund's performance with the performance of its peer group of funds as classified by Morningstar, Inc. (Morningstar), an independent provider of investment company data, and with the performance of the Fund's benchmark index. The Trustees considered that the Fund's annualized total return was in the first quintile of its Morningstar category for the one year period ended June 30, 2013, in the second quintile of its Morningstar category for the three year period ended June 30, 2013, and in the fourth quintile of its Morningstar category for the five year period ended June 30, 2013. The Trustees also considered that the Fund's yield (for the twelve months ended June 30, 2013) exceeded the yield of the Fund's benchmark index for the same period. The Trustees noted the discussions held throughout the year regarding the Fund's performance and confirmed that those discussions were factored into the Trustees' deliberations concerning the renewal of the advisory agreement. The Trustees indicated that they were satisfied with the discussions with PIM with respect to the Fund's performance. 38 Pioneer High Income Municipal Fund | Semiannual Report | 2/28/14 Management Fee and Expenses The Trustees considered information showing the fees and expenses of the Fund in comparison to the management fees and expense ratios of its peer group of funds as classified by Morningstar and also to the expense ratios of a peer group of funds selected on the basis of criteria determined by the Independent Trustees for this purpose using data provided by Strategic Insight Mutual Fund Research and Consulting, LLC (Strategic Insight), an independent third party. The Trustees considered that the Fund's management fee for the twelve months ended June 30, 2013 was in the third quintile relative to the management fees paid by other funds in its Morningstar peer group for the comparable period. The Trustees also considered the breakpoints in the management fee schedule and the reduced fee rates above certain asset levels. The Trustees considered that the Fund's expense ratio for the twelve months ended June 30, 2013 was in the fifth quintile relative to its Morningstar peer group and in the fourth quintile relative to its Strategic Insight peer group, in each case for the comparable period. The Trustees noted that the Fund's expense ratio was approximately seven basis points higher than the median expense ratio of the Fund's Morningstar peer group, and approximately three basis points higher than the median expense ratio of the Fund's Strategic Insight peer group. The Trustees considered the impact of transfer agency, sub-transfer agency, and other non-management fee expenses on the expense ratios of the Fund, and noted the impact of expenses relating to small accounts and omnibus accounts on transfer and sub-transfer agency expenses generally. The Trustees noted that they separately review the Fund's transfer agency, sub-transfer agency and intermediary arrangements. The Trustees reviewed management fees charged by PIM and PIM's affiliate, Pioneer Institutional Asset Management, Inc. (together with PIM, "Pioneer") to institutional and other clients, including publicly offered European funds sponsored by affiliates of Pioneer, unaffiliated U.S. registered investment companies (in a sub-advisory capacity), and unaffiliated foreign and domestic separate accounts. The Trustees also considered PIM's costs in providing services to the Fund and Pioneer's costs in providing services to the other clients and considered the differences in management fees and profit margins for Fund and non-Fund services. In evaluating the fees associated with Pioneer's client accounts, the Trustees took into account the respective demands, resources and complexity associated with the Fund and client accounts. The Trustees noted that, in some instances, the fee rates for those clients were lower than the management fee for the Fund and considered that, Pioneer High Income Municipal Fund | Semiannual Report | 2/28/14 39 under the investment advisory agreement with the Fund, PIM performs additional services for the Fund that it does not provide to those other clients or services that are broader in scope, including oversight of the Fund's other service providers and activities related to compliance and the extensive regulatory and tax regimes to which the Fund is subject. The Trustees also considered the different entrepreneurial risks associated with PIM's management of the Fund and Pioneer's management of the other client accounts. The Trustees concluded that the management fee payable by the Fund to PIM was reasonable in relation to the nature and quality of the services provided by PIM. Profitability The Trustees considered information provided by PIM regarding the profitability of PIM with respect to the advisory services provided by PIM to the Fund, including the methodology used by PIM in allocating certain of its costs to the management of the Fund. The Trustees also considered PIM's profit margin in connection with the overall operation of the Fund. They further reviewed the financial results realized by PIM and its affiliates from non-fund businesses. The Trustees considered PIM's profit margins with respect to the Fund in comparison to the limited industry data available and noted that the profitability of any adviser was affected by numerous factors, including its organizational structure and method for allocating expenses. The Trustees concluded that PIM's profitability with respect to the management of the Fund was not unreasonable. Economies of Scale The Trustees considered PIM's views relating to economies of scale in connection with the Pioneer Funds as fund assets grow and the extent to which any such economies of scale are shared with funds and fund shareholders. The Trustees noted the breakpoints in the management fee schedule. The Trustees recognize that economies of scale are difficult to identify and quantify, rarely identifiable on a fund-by-fund basis, and that, among other factors that may be relevant, are the following: fee levels, expense subsidization, investment by PIM in research and analytical capabilities and PIM's commitment and resource allocation to the Fund. The Trustees noted that profitability also may be an indicator of the availability of any economies of scale, although profitability may vary for other reasons particularly, for example during the recent difficult periods for financial markets, as the level of services was maintained notwithstanding a significant decline in PIM's fee revenues from the Fund. Accordingly, the Trustees concluded that economies of scale, if any, were being appropriately shared with the Fund. 40 Pioneer High Income Municipal Fund | Semiannual Report | 2/28/14 Other Benefits The Trustees considered the other benefits to PIM from its relationship with the Fund. The Trustees considered the character and amount of fees paid by the Fund, other than under the investment advisory agreement, for services provided by PIM and its affiliates. The Trustees further considered the revenues and profitability of PIM's businesses other than the fund business. The Trustees considered the intangible benefits to PIM by virtue of its relationship with the Fund and the other Pioneer funds. The Trustees concluded that the receipt of these benefits was reasonable in the context of the overall relationship between PIM and the Fund. Conclusion After consideration of the factors described above as well as other factors, the Trustees, including all of the Independent Trustees, concluded that the investment advisory agreement between PIM and the Fund, including the fees payable thereunder, was fair and reasonable and voted to approve the proposed renewal of the investment advisory agreement for the Fund.

Consumer incomes, savings, wealth, and debt-servicing capacity have been solid buttresses for the recovering housing and auto industries. Industrial activity is growing only moderately, but current corporate profits are generally solid and balance sheets appear able to support needed capital spending and dividend* payouts. Tax hikes, spending restraint and a better economy have meaningfully cut the federal budget deficit. A modestly improving European economy and continuing economic improvement in Japan appear likely to result in improving global growth in 2014, further supporting the U.S. economy. In addition, we feel that continuing slack in labor markets and capacity utilization offer the potential for continuing growth without bottlenecks and rising inflation. After observing the strengthening economic trends, the Federal Reserve (the Fed) has begun scaling back its QE (quantitative easing) program, but short-term interest rates remain near zero, and while Fed Chair Janet Yellen has hinted that rates may be raised sooner than anticipated, market expectations are still focused on no earlier than 2015. There are certainly risks and uncertainties still facing the global economy as 2014 moves along. The European economy, while improving, remains weak, the Japanese economy faces a tax hike this spring, and a number of emerging market countries are experiencing difficulties. There are also geopolitical worries abroad, such as Russia's aggressive move against Ukraine, and more potential political fights at home, especially during a mid-term election year. While most of the widely recognized risks we have outlined may already be "priced into" the market, we believe investors should continue to expect 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. Our advice, as always, is to work closely with a trusted financial advisor to discuss your goals and work together to develop an investment strategy that meets your individual needs, keeping in mind that there is no single best strategy that works for every investor. * Dividends are not guaranteed. 2 Pioneer Absolute Return Bond Fund | Semiannual Report | 2/28/14 Pioneer's investment teams have, since 1928, sought out attractive opportunities in global equity and bond markets, using in-depth research to identify undervalued individual securities, and using thoughtful risk management to construct portfolios which seek to balance potential risks and rewards in an ever-changing world. We encourage you to learn more about Pioneer and our time-tested approach to investing by consulting with your financial advisor or visiting us online at us.pioneerinvestments.com. We greatly appreciate your trust in us, and we thank you for investing with Pioneer. Sincerely, /s/ Daniel K. Kingsbury Daniel K. Kingsbury President and CEO Pioneer Investment Management USA, Inc.

These statements should not be relied upon for any other purposes. Past performance is no guarantee of future results, and there is no guarantee that market forecasts discussed will be realized. Pioneer Absolute Return Bond Fund | Semiannual Report | 2/28/14 3 Portfolio Management Discussion | 2/28/14 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 semiannual reporting period beginning with the Fund's inception on January 30, 2014, and ending February 28, 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 How did the Fund perform during the abbreviated semiannual reporting period ended February 28, 2014? A Pioneer Absolute Return Bond Fund's Class A shares returned -0.70% at net asset value during the period between January 30, 2014, and February 28, 2014. During the one-month period ended February 28, 2014, the Fund's benchmark, the Bank of America Merrill Lynch (BofA ML) 3-Month U.S. Treasury-Bill Index, returned 0.00%. 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 in a range of up to 4%. 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 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 4 Pioneer Absolute Return Bond Fund | Semiannual Report | 2/28/14 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. 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 Can you review the principal portfolio investment strategies you implemented during the Fund's abbreviated semiannual reporting period ended February 28, 2014? A In addition to the portfolio's core position in three-month Treasuries, we have implemented a number of different positions across the alpha portion of the portfolio. Among the more significant alpha-oriented positions in the Fund is a short exposure to European credit spreads. This positioning is based on our view that spreads (yield differences) between lower- and higher-quality credits within the region have narrowed past the point of fair value. As a result, the Fund is in effect positioned for higher yield differentials in the relatively near future to compensate for the risks associated with lower-quality issues. Looking at the U.S. market, our assessment is that bond prices do not fully reflect the likely extent of interest-rate increases as the U.S. Federal Reserve (the Fed) continues to gradually draw down its very accommodative monetary policies. In particular, we expect shorter-term rates to be affected in a meaningful way in 2014 once markets digest the outlook for a higher Federal funds rate. We have used a variety of instruments to implement a portfolio exposure that we believe will benefit the Fund's performance under such a scenario. At the same time, we expect the U.S. dollar to benefit from rising U.S. interest rates, and the Fund, consequently, has a long U.S. dollar position versus the Japanese yen. As the Fund began investment operations at the end of January, in looking at European sovereign-debt levels, we viewed the yield level on Italy's 10-year maturity bond as insufficient and reflective of undue levels of optimism concerning the recovery of the Italian economy. As a result, we took a short position in Italian 10-year bonds, expecting their yields to rise. However, that position began to work against the Fund's returns and we eliminated it before the end of the period. Finally, we implemented a Fund position designed to benefit from higher inflation in Japan, and that has * Diversification does not assure a profit nor protect against loss in a declining market. Pioneer Absolute Return Bond Fund | Semiannual Report | 2/28/14 5 worked out well so far. The positioning was based in large part on our view that the efforts by Japan's government to inflate the country's economy would meet with some success. Q What is your assessment of the current macroeconomic climate and the opportunities it may present? A We expect volatility to be a feature of the investment backdrop in 2014, 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 data releases. The Fed's bond purchases are currently on a track to end in November 2014, and Fed Chair Janet Yellen recently suggested that an increase in the Federal funds rate could follow six months after the "tapering" of bond purchases is finished. In our view, the markets have not fully digested the implications this policy shift may have on U.S. interest rates, or for the U.S. dollar as rates increase. Our outlook for fixed-income markets in Europe is more favorable. Despite its common currency, Europe continues to deal with a two-tier economy. Rather than hiking interest rates, there is a real question as to whether or not the European Central Bank will feel compelled to step up with more policy support for the weaker euro zone economies. These are just some of the macroeconomic factors we will monitor closely as we seek to inform the various positions implemented within the alpha-oriented portion of the Fund's portfolio. Please refer to the Schedule of Investments on pages 15-21 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. 6 Pioneer Absolute Return Bond Fund | Semiannual Report | 2/28/14 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. 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. Please see the prospectus for a more complete discussion of the Fund's risks. Past performance is no guarantee of future results, and there is no guarantee that market forecasts discussed will be realized.

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 Paid on a $1,000 Investment in Pioneer Absolute Return Bond Fund Based on actual returns from January 31, 2014, through February 28, 2014. -------------------------------------------------------------------------------- Share Class A C Y -------------------------------------------------------------------------------- Beginning Account Value on 1/31/14 $1,000.00 $1,000.00 $1,000.00 -------------------------------------------------------------------------------- Ending Account Value (after expenses) on 2/28/14 $ 997.00 $ 996.00 $ 997.00 -------------------------------------------------------------------------------- Expenses Paid During Period* $ 0.79 $ 1.39 $ 0.59 -------------------------------------------------------------------------------- * Expenses are equal to the Fund's annualized net expense ratio of 1.00%, 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 29/365 (to reflect the partial year period). Pioneer Absolute Return Bond Fund | Semiannual Report | 2/28/14 13 Hypothetical Example for Comparison Purposes The table below provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the tables are meant to highlight your ongoing costs only and do not reflect any transaction costs, such as sales charges (loads) that are charged at the time of the transaction. Therefore, the table below is useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds. In addition, if these transaction costs were included, your costs would have been higher.

Organization and Significant Accounting Policies Pioneer Absolute 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 | Semiannual Report | 2/28/14 29 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. 30 Pioneer Absolute Return Bond Fund | Semiannual Report | 2/28/14 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 February 28, 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. All discounts/premiums on debt securities are accreted/amortized into interest income for financial reporting purposes. 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 prices of those securities but are included with the net realized and unrealized gain or loss on investments. Pioneer Absolute Return Bond Fund | Semiannual Report | 2/28/14 31 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 February 28, 2014 was $25,499. 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.

Forward Foreign Currency Contracts The Fund may enter into forward foreign currency contracts (contracts) for the purchase or sale of a specific foreign currency at a fixed price on a future date. All contracts are marked to market daily at the applicable exchange rates, and any resulting unrealized appreciation or depreciation is recorded in the Fund's financial statements. The Fund records realized gains and losses at the time a contract is offset by entry into a closing transaction or extinguished by delivery of the currency. Risks may arise upon entering into these contracts from the potential inability of counterparties to meet the terms of the contract and from unanticipated movements in the value of foreign currencies relative to the U.S. dollar (see Note 6). E. Federal Income Taxes It is the Fund's policy to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its taxable income and net realized capital gains, if any, to its shareowners. Therefore, no federal income tax provision is required. As of February 28, 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. 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 February 28, 2014. Pioneer Absolute Return Bond Fund | Semiannual Report | 2/28/14 33 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 34 Pioneer Absolute Return Bond Fund | Semiannual Report | 2/28/14 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 value of option contracts open for one month in the period ended February 28, 2014 was $4,979. 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 four written put option contracts that were open at February 28, 2014. If the put options were exercised at February 28, 2014, the maximum amount the Fund would have been required to pay was $2,471. The Fund held two written call option contracts that were open at February 28, 2014. If the put options were exercised at February 28, 2014, the maximum amount the Fund would have been required to pay was $2,507. Transactions in written options for the period ended February 28, 2014 are summarized as follows: ----------------------------------------------------------------------------- Number of Premium Contracts Paid ----------------------------------------------------------------------------- Options open at beginning of period -- $ -- Options opened (1,747,000) (5,788) Options exercised -- -- Options closed -- -- Options expired -- -- ----------------------------------------------------------------------------- Options open at end of period (1,747,000) (5,788) ============================================================================= 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 35 Pioneer Absolute Return Bond Fund | Semiannual Report | 2/28/14 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 value of purchased options open for one month in the period ended February 28, 2014 was $19,693. Purchased option contracts outstanding at period end are listed at the end of the Fund's schedule of investments. K. 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. When the Fund purchases a 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 appreciation or depreciation is recorded in the Fund's financial statements. Premiums paid for purchased swaptions, which have expired, are treated as realized losses on investments in the Statement of Operations. Upon the exercise or closing of a purchased swaption, the cost basis of the swap is adjusted by the amount of premium paid in order to determine the realized gain or loss on investments. The risk associated with purchasing swaptions is limited to the premium originally paid. 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 February 28, 2014 are listed in the Schedule of Investments. The value of purchased swaption contracts open for one month in the period ended February 28, 2014 was $245,073. 36 Pioneer Absolute Return Bond Fund | Semiannual Report | 2/28/14 L. 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 to 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. Pioneer Absolute Return Bond Fund | Semiannual Report | 2/28/14 37 Open credit default swap contracts at February 28, 2014 are listed in the Schedule of Investments. The value of credit default swap contracts open for one month in the period ended February 28, 2014 was $7,603,322. M. 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 February 28, 2014 are listed in the Schedule of Investments. The value of cross currency swap contracts open for one month in the period ended February 28, 2014 was $2,917,980. N. 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. 38 Pioneer Absolute Return Bond Fund | Semiannual Report | 2/28/14 Open inflation rated swap contracts at February 28, 2014 are listed in the Schedule of Investments. The value of inflation rate swap contracts open for the one month in the period ended February 28, 2014 was $4,280,231. O. 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.

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 Eurodollar rate on the borrowing date. The Funds pay an annual commitment to participate in a credit facility. The commitment fee is allocated among participating Funds based on an allocation schedule set forth in the credit agreement. For the period ended February 28, 2014, the Fund had no borrowings under the credit facility. 42 Pioneer Absolute Return Bond Fund | Semiannual Report | 2/28/14 8.

(PIM) serves as the investment adviser to Pioneer Absolute Return Bond Fund (the Fund) pursuant to an investment advisory agreement between PIM and the Fund. Based on their evaluation of the information provided by PIM, the Trustees, including the Independent Trustees voting separately, unanimously approved an investment advisory agreement for the Fund. In considering the investment advisory agreement, the Trustees considered various factors that they determined were relevant, including the factors described below. In all quintile rankings referred to throughout this disclosure, the first quintile is most favorable to Fund shareowners. The Trustees did not identify any single factor as the controlling factor in determining to approve the agreement. Nature, Extent and Quality of Services The Trustees considered the nature, extent and quality of the services that would be provided by PIM to the Fund under the investment advisory agreement. The Trustees reviewed PIM's investment approach for the Fund and its research process, and considered the resources of PIM and the personnel of PIM who would provide investment management services to the Fund. The Trustees also considered that, as administrator, PIM would be responsible for the administration of the Fund's business and other affairs. The Trustees considered the quality of such services provided by PIM to the other Pioneer Funds. The Trustees considered the fees to be paid to PIM for the provision of administration services. Based on these considerations, the Trustees concluded that the nature, extent and quality of services that PIM would provide to the Fund were satisfactory and consistent with the terms of the investment advisory agreement. Performance of the Fund The Trustees did not consider the Fund's performance in approving the investment advisory agreement because the Fund was newly-offered and did not have a performance history. The Trustees noted the performance results of a UCITS fund managed by Pioneer, and discussed in detail how the management of the Fund would differ from the management of the UCITS fund. Management Fee and Expenses The Trustees considered information compiled by Strategic Insight Simfund, an independent third party, to compare the Fund's proposed management fee and anticipated expense ratio with a peer group of funds included in the Morningstar Non-Traditional Bond category. The Trustees considered that the 46 Pioneer Absolute Return Bond Fund | Semiannual Report | 2/28/14 Fund's proposed management fee would rank in the fourth quintile of the peer group, and in the third quintile of a subset of the peer group consisting of funds that pursue an investment approach similar to the Fund's investment approach. The Trustees considered factors distinguishing the Fund from the funds in the peer group. The Trustees also considered that, taking into account the contractual expense limitation agreed to by PIM with respect to the Fund, the Fund's anticipated expense ratio would rank at the top of the fifth quintile of the peer group, and at the top of the fourth quintile of the subset of the peer group consisting of funds that pursue an investment approach similar to the Fund's investment approach. The Trustees concluded that the proposed management fee payable by the Fund to PIM was reasonable in relation to the nature and quality of services to be provided by PIM. Profitability The Trustees did not consider PIM's profitability with respect to the management of the Fund in approving the investment advisory agreement because the Fund was newly-offered and profitability information was not available. Economies of Scale The Trustees considered PIM's views relating to economies of scale in connection with the Pioneer Funds as fund assets grow and the extent to which any such economies of scale are shared with funds and fund shareholders. The Trustees concluded that economies of scale, if any, would be appropriately shared with the Fund. Other Benefits The Trustees considered the other potential benefits to PIM from its relationship with the Fund, including the character and amount of fees that would be paid by the Fund, other than under the investment advisory agreement, for services that would be provided by PIM and its affiliates, and the revenues and profitability of PIM's businesses other than the fund business. The Trustees concluded that the receipt of these benefits was reasonable in the context of the overall relationship between PIM and the Fund. Conclusion After consideration of the factors described above as well as other factors, the Trustees, including all of the independent Trustees, concluded that the investment advisory agreement between PIM and the Fund, including the fees payable thereunder, was fair and reasonable and voted to approve the investment advisory agreement for the Fund.

Consumer incomes, savings, wealth, and debt-servicing capacity have been solid buttresses for the recovering housing and auto industries. Industrial activity is growing only moderately, but current corporate profits are generally solid and balance sheets appear able to support needed capital spending and dividend* payouts. Tax hikes, spending restraint and a better economy have meaningfully cut the federal budget deficit. A modestly improving European economy and continuing economic improvement in Japan appear likely to result in improving global growth in 2014, further supporting the U.S. economy. In addition, we feel that continuing slack in labor markets and capacity utilization offer the potential for continuing growth without bottlenecks and rising inflation. After observing the strengthening economic trends, the Federal Reserve (the Fed) has begun scaling back its QE (quantitative easing) program, but short-term interest rates remain near zero, and while Fed Chair Janet Yellen has hinted that rates may be raised sooner than anticipated, market expectations are still focused on no earlier than 2015. There are certainly risks and uncertainties still facing the global economy as 2014 moves along. The European economy, while improving, remains weak, the Japanese economy faces a tax hike this spring, and a number of emerging market countries are experiencing difficulties. There are also geopolitical worries abroad, such as Russia's aggressive move against Ukraine, and more potential political fights at home, especially during a mid-term election year. While most of the widely recognized risks we have outlined may already be "priced into" the market, we believe investors should continue to expect 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. Our advice, as always, is to work closely with a trusted financial advisor to discuss your goals and work together to develop an investment strategy that meets your individual needs, keeping in mind that there is no single best strategy that works for every investor. * Dividends are not guaranteed. 2 Pioneer Long/Short Global Bond Fund | Semiannual Report | 2/28/14 Pioneer's investment teams have, since 1928, sought out attractive opportunities in global equity and bond markets, using in-depth research to identify undervalued individual securities, and using thoughtful risk management to construct portfolios which seek to balance potential risks and rewards in an ever-changing world.

Pioneer Long/Short Global Bond Fund | Semiannual Report | 2/28/14 3 Portfolio Management Discussion | 2/28/14 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 semiannual reporting period beginning with the Fund's inception on December 30, 2013, and ending February 28, 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 How did the Fund perform during the abbreviated semiannual reporting period ended February 28, 2014? A Pioneer Long/Short Global Bond Fund's Class A shares returned 0.00% at net asset value during the period between December 30, 2013, and February 28, 2014. During the two-month period ended February 28, 2014, the Fund's benchmark, the Bank of America Merrill Lynch (BofA ML) 3-Month U.S. Treasury-Bill Index, returned 0.01%. Q Can you provide an overview of the Fund's approach? A The big picture is that we aim to have the Fund's annualized return exceed that of 3-month Treasury bills, with portfolio volatility that is about the same as the broad fixed-income market. To achieve that goal, we seek to provide positive Fund 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 Fund returns regardless of market conditions, we utilize two distinct investment strategies. One part of the portfolio's strategy is directional, in that we need to be correct about whether the prices of a particular asset class are poised to go up or down. However, we seek to have the Fund benefit from both positive and negative returns. This means that at times we invest 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, under 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 a segment 4 Pioneer Long/Short Global Bond Fund | Semiannual Report | 2/28/14 or security within a market that 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. We believe this strategy can allow the Fund to benefit from favorable relative performance, regardless of the overall direction of that market. Perhaps 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 Can you review the principal portfolio investment strategies you implemented during the Fund's abbreviated semiannual reporting period ended February 28, 2014? A On the directional side of the portfolio, we implemented a number of long exposures. These include holdings of euro-denominated bonds that are convertible into equities. With these positions, we are seeking to have the Fund benefit from an improvement in the European stock market, where we think margin stabilization and modest price-to-earnings (P/E) expansion could translate into solid risk-adjusted returns. In particular, we have been emphasizing investments in economically sensitive financial and service-oriented firms with less exposure to France and Italy. Within the U.S., we are positive on business development companies, which are significantly-regulated entities specializing in lending to small- and mid-size companies. Stocks of such companies generally carry little exposure to non-domestic risks. It is our belief that the U.S. economy will grow more robustly than consensus market estimates, which supports our taking the portfolio's long positions in equities. The Fund also had meaningful exposure to securitized credit markets such as non-agency mortgages, an area where we see opportunities 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 in the portfolio, we are trying to isolate the cheapness of mortgage bonds. Finally, the Fund held a variety of event-linked bonds, which are designed to pay reasonable yields in exchange for insurance protection against major calamities such as hurricanes, floods, and earthquakes. We like event-linked bonds because of their historical lack of correlation to any equity or fixed-income market risks. Pioneer Long/Short Global Bond Fund | Semiannual Report | 2/28/14 5 On the short side of the directional portfolio, we took a position with respect to investment-grade debt in both Asia and Australia, areas that we view as being vulnerable to the credit slowdown in China. China is attempting to grow its economy at a 7.5% annual pace, while at the same time contracting credit and relying on a shadow banking system that represents approximately 70% of the country's gross domestic product (GDP). We felt that investments in both the Asian and Australian credit markets are a prudent and efficient way to get short exposure in the event of a Chinese policy error. We are also shorting the portfolio at a very specific point on the U.S. yield curve, as we do not believe the markets are adequately prepared for the likely pace of the U.S. Federal Reserve's (the Fed's) tightening of its accommodative monetary policy should the domestic economy return to above-trend growth. We also implemented a number of strategies within the portion of the Fund's portfolio that utilizes trades with low correlations to the broader markets. One of our core strategies ("global macro") seeks to benefit from market distortions in relative value that often result from macroeconomic factors. Currency long/short is a strategy whereby we take long portfolio positions in a basket of emerging and developed market currencies, and shorter positions in another basket of currencies that we expect to underperform. Another portfolio strategy which we implemented was long/short credit. This entails pairing long and short positions in two issuers within the same industry sector for whom we expect performance to diverge. We also initiated long/short trades within the portfolio's long/short equity strategy, with one key position favoring regional banks with a domestic focus over large-capitalized U.S. stocks with more global exposure--particularly those with exposure to the emerging markets. Another key strategy within the portfolio's long/short equity sleeve is a pairing that favors Spain -- a country that has made meaningful strides with respect to restructuring its economy -- over other parts of the euro zone. Under the Fund's capital structure arbitrage investment strategy, we seek to take advantage of mispricings within different parts of the capital structure. We attempt to do this by, for instance, purchasing a firm's junior debt securities if we believe their prices reflect an unrealistically high assessment of the company's default risk, while simultaneously purchasing tradable insurance in the form of a credit default swap on the firm's senior debt. This strategy can add to the Fund's return if we are correct in our assessment and the prices of the two different issues converge. Finally, the Fund has a number of curve trades as part of the credit long/short strategy, where the portfolio is long in one part of an individual issuer's yield curve, and short in another part, depending on whether we believe the issuer's yield curve will steepen or flatten. 6 Pioneer Long/Short Global Bond Fund | Semiannual Report | 2/28/14 Q What is your assessment of the current macroeconomic climate and the 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 its historic long-term trend, supported by improvements in employment and the availability of credit. At the same time, there will be disappointments along the way, and with the Fed no longer fully committed to stepping up its accommodative efforts to backstop economic 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 conditions in the emerging versus developed markets. Many emerging economies are actually in a better position from the standpoint of national debt levels and current account flows, and we anticipate that performance trends in global bond markets will become increasingly country-specific. Market volatility and performance dispersion creates opportunities for an uncorrelated trading strategy such as ours, and we will seek to find trades that will help the Fund to capitalize on emerging themes. 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. 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. Pioneer Long/Short Global Bond Fund | Semiannual Report | 2/28/14 7 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. 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. Past performance is no guarantee of future results, and there is no guarantee that market forecasts discussed will be realized.

Pioneer Long/Short Global Bond Fund | Semiannual Report | 2/28/14 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 Paid on a $1,000 Investment in Pioneer Long/Short Global Bond Fund Based on actual returns from December 31, 2013, through February 28, 2014. -------------------------------------------------------------------------------- Share Class A C Y -------------------------------------------------------------------------------- Beginning Account Value on 12/31/13 $1,000.00 $1,000.00 $1,000.00 -------------------------------------------------------------------------------- Ending Account Value (after expenses) on 2/28/14 $1,000.00 $ 999.00 $1,000.00 -------------------------------------------------------------------------------- Expenses Paid During Period* $ 2.55 $ 3.78 $ 2.14 -------------------------------------------------------------------------------- * Expenses are equal to the Fund's annualized net expense ratio of 1.55%, 2.30% and 1.30% for Class A, Class C, and Class Y shares, respectively, multiplied by the average account value over the period, multiplied by 60/365 (to reflect the partial year period). 14 Pioneer Long/Short Global Bond Fund | Semiannual Report | 2/28/14 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. Expenses Paid on a $1,000 Investment in Pioneer Long/Short Global Bond Fund Based on a hypothetical 5% return per year before expenses, reflecting the period from December 31, 2013, through February 28, 2014. -------------------------------------------------------------------------------- Share Class A C Y -------------------------------------------------------------------------------- Beginning Account Value on 12/31/13 $1,000.00 $1,000.00 $1,000.00 -------------------------------------------------------------------------------- Ending Account Value (after expenses) on 2/28/14 $1,005.67 $1,004.44 $1,006.08 -------------------------------------------------------------------------------- Expenses Paid During Period* $ 2.56 $ 3.79 $ 2.14 -------------------------------------------------------------------------------- * Expenses are equal to the Fund's annualized net expense ratio of 1.55%, 2.30% and 1.30% for Class A, Class C, and Class Y shares, respectively, multiplied by the average account value over the period, multiplied by 60/365 (to reflect the partial year period).

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 | Semiannual Report | 2/28/14 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 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 34 Pioneer Long/Short Global Bond Fund | Semiannual Report | 2/28/14 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 February 28, 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. All discounts/premiums on debt securities are accreted/amortized into interest income for financial reporting purposes. 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 prices of those securities but are included with the net realized and unrealized gain or loss on investments. Pioneer Long/Short Global Bond Fund | Semiannual Report | 2/28/14 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 February 28, 2014 was $88,185. 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 February 28, 2014 was $4,173,861. At February 28, 2014, open futures contracts were as follows: -------------------------------------------------------------------------------- Number of Unrealized Contracts Settlement Appreciation/ Type Long/(Short) Month Value (Depreciation) -------------------------------------------------------------------------------- 90 Days Europe Futures (26) 12/16 $ (6,370,325) $ (5,363) 5 Years U.S. Treasury Note (10) 3/14 (1,209,063) (1,984) S&P 500 EMINI Futures (7) 6/14 (647,710) (4,270) -------------------------------------------------------------------------------- Total $ (11,617) ================================================================================ 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). 36 Pioneer Long/Short Global Bond Fund | Semiannual Report | 2/28/14 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 February 28, 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. The tax character of current year distributions payable will be determined at the end of the Fund's taxable year. 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 February 28, 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). Pioneer Long/Short Global Bond Fund | Semiannual Report | 2/28/14 37 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 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. 38 Pioneer Long/Short Global Bond Fund | Semiannual Report | 2/28/14 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 February 28, 2014 are listed in the Schedule of Investments. The average value of swap contracts open during the period ended February 28, 2014 was $7,818,074. 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 up to $1 billion of the Fund and 0.95% of the Fund's average daily net assets over $1 billion of the Fund. For the period ending February 28, 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 February 28, 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. Pioneer Long/Short Global Bond Fund | Semiannual Report | 2/28/14 39 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 $9,433 in management fees, administrative costs and certain other reimbursements payable to PIM at February 28, 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 February 28, 2014, there were no out-of-pocket expenses, transfer agents fees and out-of-pocket reimbursements payable. 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 $571 in distribution fees payable to PFD at February 28, 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 R, Class Y or Class Z shares. Proceeds from the CDSC are paid to PFD. For the period ended February 28, 2014, there were no CDSCs paid to PFD. 40 Pioneer Long/Short Global Bond Fund | Semiannual Report | 2/28/14 5. Forward Foreign Currency Contracts At February 28, 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 February 28, 2014 was $2,492,317. Open forward foreign currency contracts at February 28, 2014 were as follows: ------------------------------------------------------------------------------------------ Net Net Unrealized Contracts to In Exchange Settlement Appreciation Currency Deliver For Date Value (Depreciation) ------------------------------------------------------------------------------------------ BRL (Brazilian Real) (1,308,576) $ (557,943) 3/6/14 $ 560,802 $ 2,859 BRL (Brazilian Real) 1,308,576 (539,263) 3/6/14 557,943 18,680 CAD (Canadian Dollar) (261,211) (236,026) 3/6/14 236,342 316 CHF (Swiss Franc) (331,809) (377,683) 3/6/14 368,221 (9,462) CLP (Chilean Peso) (194,715,981) (348,218) 3/6/14 346,408 (1,810) CZK (Czech Republic Koruna) (9,864,341) (498,911) 3/6/14 485,290 (13,621) EURO (European Euro) 109,333 151,090 5/5/14 (147,483) 3,607 EURO (European Euro) (883,931) (1,221,530) 5/5/14 1,194,370 (27,160) EURO (European Euro) (538,300) (743,903) 3/6/14 728,856 (15,047) GBP (British Pound Sterling) (240,887) (403,494) 5/6/14 396,674 (6,820) GBP (British Pound Sterling) (223,744) (374,956) 3/6/14 363,977 (10,979) HUF (Hungarian Forint) (53,707,909) (239,714) 3/6/14 235,838 (3,876) IDR (Indonesian Rupiah) 2,236,180,276 (185,267) 3/6/14 192,560 7,293 INR (Indian Rupee) 26,707,736 (425,012) 3/6/14 432,269 7,257 JPY (Japanese Yen) (63,967,096) (628,459) 3/6/14 634,420 5,961 KRW (South Korean Won) 130,413,071 (120,798) 3/6/14 122,272 1,474 MXN (Mexican Peso) 4,805,140 (358,771) 3/6/14 361,992 3,221 NGN (Nigerian Naira) 10,456,083 (62,424) 3/18/14 63,018 594 NOK (Norwegian Krone) 754,540 (120,726) 3/6/14 125,846 5,120 NZD (New Zealand Dollar) 738,391 (606,602) 3/6/14 619,610 13,008 PLN (Polish Zloty) (241,011) (241,010) 3/6/14 248,648 7,638 RUB (Russian Ruble) 6,098,676 169,348 3/6/14 (174,015) (4,667) SEK (Swedish Krone) 797,501 (122,226) 3/6/14 124,561 2,335 SGD (Singapore Dollar) (465,575) (367,260) 3/6/14 367,157 (103) TRY (Turkish Lira) (266,835) (120,824) 3/6/14 118,118 (2,706) TWD (New Taiwan Dollar) (7,343,525) 242,241 3/6/14 (242,372) (131) ------------------------------------------------------------------------------------------ Total $(17,019) ========================================================================================== Pioneer Long/Short Global Bond Fund | Semiannual Report | 2/28/14 41 6. 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 period ended February 28, 2014, the Fund's expenses were not reduced under such arrangements. 7. 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. For the period ended February 28, 2014, the Fund had no borrowings under the credit facility. 42 Pioneer Long/Short Global Bond Fund | Semiannual Report | 2/28/14 8.

(PIM) serves as the investment adviser to Pioneer Long/Short Global Bond Fund (the Fund) pursuant to an investment advisory agreement between PIM and the Fund. Based on their evaluation of the information provided by PIM, the Trustees, including the Independent Trustees voting separately, unanimously approved an investment advisory agreement for the Fund. In considering the investment advisory agreement, the Trustees considered various factors that they determined were relevant, including the factors described below. In all quintile rankings referred to throughout this disclosure, the first quintile is most favorable to Fund share-owners. The Trustees did not identify any single factor as the controlling factor in determining to approve the agreement. Nature, Extent and Quality of Services The Trustees considered the nature, extent and quality of the services that would be provided by PIM to the Fund under the investment advisory agreement. The Trustees reviewed PIM's investment approach for the Fund and its research process, and considered the resources of PIM and the personnel of PIM who would provide investment management services to the Fund. The Trustees also considered that, as administrator, PIM would be responsible for the administration of the Fund's business and other affairs. The Trustees considered the quality of such services provided by PIM to the other Pioneer Funds. The Trustees considered the fees to be paid to PIM for the provision of administration services. Based on these considerations, the Trustees concluded that the nature, extent and quality of services that PIM would provide to the Fund were satisfactory and consistent with the terms of the investment advisory agreement. Performance of the Fund The Trustees did not consider the Fund's performance in approving the invest- ment advisory agreement because the Fund was newly-offered and did not have a performance history. Management Fee and Expenses The Trustees considered information compiled by Strategic Insight Simfund, an independent third party, to compare the Fund's proposed management fee and anticipated expense ratio with a peer group of funds included in the Morningstar Non-Traditional Bond category. The Trustees considered that the Fund's proposed management fee would rank in the fifth quintile of the peer group, and just over the median management fee of a subset of the peer group consisting of funds that pursue an investment approach similar to the Fund's Pioneer Long/Short Global Bond Fund | Semiannual Report | 2/28/14 45 investment approach. The Trustees considered factors distinguishing the Fund from the funds in the peer group. The Trustees also considered that, taking into account the contractual expense limitation agreed to by PIM with respect to the Fund, the Fund's anticipated expense ratio would rank in the fifth quintile of the peer group, and in the third quintile of the subset of the peer group consisting of funds that pursue an investment approach similar to the Fund's investment approach. The Trustees concluded that the proposed management fee payable by the Fund to PIM was reasonable in relation to the nature and quality of services to be provided by PIM. Profitability The Trustees did not consider PIM's profitability with respect to the manage- ment of the Fund in approving the investment advisory agreement because the Fund was newly-offered and profitability information was not available. Economies of Scale The Trustees considered PIM's views relating to economies of scale in connection with the Pioneer Funds as fund assets grow and the extent to which any such economies of scale are shared with funds and fund shareholders. The Trustees concluded that economies of scale, if any, would be appropriately shared with the Fund. Other Benefits The Trustees considered the other potential benefits to PIM from its relationship with the Fund, including the character and amount of fees that would be paid by the Fund, other than under the investment advisory agreement, for services that would be provided by PIM and its affiliates, and the revenues and profitability of PIM's businesses other than the fund business. The Trustees concluded that the receipt of these benefits was reasonable in the context of the overall relationship between PIM and the Fund. Conclusion After consideration of the factors described above as well as other factors, the Trustees, including all of the independent Trustees, concluded that the investment advisory agreement between PIM and the Fund, including the fees payable thereunder, was fair and reasonable and voted to approve the investment advisory agreement for the Fund. 46 Pioneer Long/Short Global Bond Fund | Semiannual Report | 2/28/14 Trustees, Officers and Service Providers Trustees Officers Thomas J.

Consumer incomes, savings, wealth, and debt-servicing capacity have been solid buttresses for the recovering housing and auto industries. Industrial activity is growing only moderately, but current corporate profits are generally solid and balance sheets appear able to support needed capital spending and dividend* payouts. Tax hikes, spending restraint and a better economy have meaningfully cut the federal budget deficit. A modestly improving European economy and continuing economic improvement in Japan appear likely to result in improving global growth in 2014, further supporting the U.S. economy. In addition, we feel that continuing slack in labor markets and capacity utilization offer the potential for continuing growth without bottlenecks and rising inflation. After observing the strengthening economic trends, the Federal Reserve (the Fed) has begun scaling back its QE (quantitative easing) program, but short-term interest rates remain near zero, and while Fed Chair Janet Yellen has hinted that rates may be raised sooner than anticipated, market expectations are still focused on no earlier than 2015. There are certainly risks and uncertainties still facing the global economy as 2014 moves along. The European economy, while improving, remains weak, the Japanese economy faces a tax hike this spring, and a number of emerging market countries are experiencing difficulties. There are also geopolitical worries abroad, such as Russia's aggressive move against Ukraine, and more potential political fights at home, especially during a mid-term election year. While most of the widely recognized risks we have outlined may already be "priced into" the market, we believe investors should continue to expect 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 Long/Short Opportunistic Credit Fund | Semiannual Report | 2/28/14 3 Portfolio Management Discussion | 2/28/14 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 semiannual reporting period beginning with the Fund's inception on December 30, 2013, and ending February 28, 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 How did the Fund perform during the abbreviated semiannual reporting period ended February 28, 2014? A Pioneer Long/Short Opportunistic Credit Fund's Class A shares returned 0.00% at net asset value during the period between December 30, 2013, and February 28, 2014. During the two-month period ended February 28, 2014, the Fund's benchmark, the Bank of America Merrill Lynch (BofA ML) 3-Month U.S. Treasury-Bill Index, returned 0.01%. Q Can you provide an overview of the Fund's investment approach? A In seeking positive Fund returns regardless of market conditions, we utilize two distinct investment strategies. One part of the portfolio's strategy is directional, in that we need to be correct about whether the prices of a particular asset class are poised to appreciate or depreciate. However, we seek to have the Fund benefit from both positive and negative returns. This means that at times we invest 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 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 4 Pioneer Long/Short Opportunistic Credit Fund | Semiannual Report | 2/28/14 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. We aim to have the Fund's annualized return exceed that of 3-month Treasury bills, but with portfolio volatility lower than that of the broad equity market. To achieve that goal, we seek to provide positive Fund returns over most trailing 12-month periods and to minimize the extent of any negative returns, regardless of market conditions. 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 Can you review the principal portfolio investment strategies you implemented during the Fund's abbreviated semiannual reporting period ended February 28, 2014? A We initiated long/short trades within the portfolio's long/short equity strategy, with one key position favoring regional banks with a domestic focus over large-capitalized U.S. stocks with more global exposure--particularly those with exposure to the emerging markets. Another key strategy within the portfolio's long/short equity sleeve is a pairing that favors Spain -- a country that has made meaningful strides with respect to restructuring its economy -- over other parts of the euro zone. Under the Fund's capital structure arbitrage investment strategy, we seek to take advantage of mispricings within different parts of the capital structure. We attempt to do this by, for instance, purchasing a firm's junior debt securities if we believe their prices reflect an unrealistically high assessment of the company's default risk, while simultaneously purchasing tradable insurance in the form of a credit default swap on the firm's senior debt. This strategy can add to the Fund's return if we are correct in our assessment and the prices of the two different issues converge. The Fund had a number of curve trades as part of the credit long/short strategy, where the portfolio is long in one part of an individual issuer's yield curve, and short in another part, depending on whether we believe the issuer's yield curve will steepen or flatten. We also implemented a number of strategies within the portion of the Fund's portfolio that utilizes trades with low correlations to the broader markets. One of our core strategies ("global macro") seeks to benefit from market distortions in relative value that often result from macroeconomic Pioneer Long/Short Opportunistic Credit Fund | Semiannual Report | 2/28/14 5 factors. Currency long/short is a strategy whereby we take long portfolio positions in a basket of emerging and developed market currencies, and shorter positions in another basket of currencies that we expect to underperform. Another portfolio strategy which we implemented was long/short credit. This entails pairing long and short positions in two issuers within the same industry sector for whom we expect performance to diverge. On the directional side of the portfolio, we implemented a number of long exposures. These include holdings of euro-denominated bonds that are convertible into equities. With these positions, we are seeking to have the Fund benefit from an improvement in the European stock market, where we think margin stabilization and modest price-to-earnings (P/E) expansion could translate into solid risk-adjusted returns. In particular, we have been emphasizing investments in economically sensitive financial and service-oriented firms with less exposure to France and Italy. On the short side of the directional portfolio, we took a position with respect to investment-grade debt in both Asia and Australia, areas that we view as being vulnerable to the credit slowdown in China. China is attempting to grow its economy at a 7.5% annual pace, while at the same time contracting credit and relying on a shadow banking system that represents approximately 70% of the country's gross domestic product (GDP). We felt that investments in both the Asian and Australian credit markets are a prudent and efficient way to get short exposure in the event of a Chinese policy error. We are also shorting the portfolio at a very specific point on the U.S. yield curve, as we do not believe the markets are adequately prepared for the likely pace of the U.S. Federal Reserve's (the Fed's) tightening of its accommodative monetary policy should the domestic economy return to above-trend growth. Within the U.S., we are positive on business development companies, which are significantly-regulated entities specializing in lending to small- and midsize companies. Stocks of such companies generally carry little exposure to non-domestic risks. It is our belief that the U.S. economy will grow more robustly than consensus market estimates, which supports our taking the portfolio's long positions in equities. The Fund also had meaningful exposure to securitized credit markets such as non-agency mortgages, an area where we see opportunities to earn reasonable risk-adjusted returns 6 Pioneer Long/Short Opportunistic Credit Fund | Semiannual Report | 2/28/14 with less sensitivity to the direction of the U.S. equity market. Because we seek to hedge out the accompanying interest-rate risk in the portfolio, we are trying to isolate the cheapness of mortgage bonds. Finally, the Fund held a variety of event-linked bonds, which are designed to pay reasonable yields in exchange for insurance protection against major calamities such as hurricanes, floods, and earthquakes. We like event-linked bonds because of their historical lack of correlation to any equity or fixed-income market risks. Q What is your assessment of the current macroeconomic climate and the 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 its historic long-term trend, supported by improvements in employment and the availability of credit. At the same time, there will be disappointments along the way, and with the Fed no longer fully committed to stepping up its accommodative efforts to backstop economic 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 conditions in the emerging versus developed markets. Many emerging economies are actually in a better position from the standpoint of national debt levels and current account flows, and we anticipate that performance trends in global bond markets will become increasingly country-specific. Market volatility and performance dispersion creates opportunities for an uncorrelated trading strategy such as ours, and we will seek to find trades that will help the Fund to capitalize on emerging themes. Please refer to the Schedule of Investments on pages 17-26 for a full listing of Fund securities. Pioneer Long/Short Opportunistic Credit Fund | Semiannual Report | 2/28/14 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 | Semiannual Report | 2/28/14 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. Past performance is no guarantee of future results, and there is no guarantee that market forecasts discussed will be realized.

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 Paid on a $1,000 Investment in Pioneer Long/Short Opportunistic Credit Fund Based on actual returns from December 31, 2013, through February 28, 2014. -------------------------------------------------------------------------------- Share Class A C Y -------------------------------------------------------------------------------- Beginning Account Value on 12/31/13 $1,000.00 $1,000.00 $1,000.00 -------------------------------------------------------------------------------- Ending Account Value (after expenses) on 2/28/14 $1,000.00 $ 999.00 $1,001.00 -------------------------------------------------------------------------------- Expenses Paid During Period* $ 2.81 $ 4.04 $ 2.40 -------------------------------------------------------------------------------- * Expenses are equal to the Fund's annualized net expense ratio plus the expense ratio of the underlying funds. These combined totals were 1.71%, 2.46% and 1.46% for Class A, Class C and Class Y shares, respectively, multiplied by the average account value over the period multiplied by 60/365 (to reflect the partial year period). Pioneer Long/Short Opportunistic Credit Fund | Semiannual Report | 2/28/14 15 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.

Pioneer Long/Short Opportunistic Credit Fund | Semiannual Report | 2/28/14 33 Notes to Financial Statements | 2/28/14 (unaudited) 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: 34 Pioneer Long/Short Opportunistic Credit Fund | Semiannual Report | 2/28/14 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. 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. Pioneer Long/Short Opportunistic Credit Fund | Semiannual Report | 2/28/14 35 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 February 28, 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. All discounts/premiums on debt securities are accreted/amortized into interest income for financial reporting purposes. 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 prices of those securities but are included with the net realized and unrealized gain or loss on investments. 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. 36 Pioneer Long/Short Opportunistic Credit Fund | Semiannual Report | 2/28/14 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 February 28, 2014 was $139,635. 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 contacts open during the period ended February 28, 2014 was $4,618,482. At February 28, 2014, open futures contracts were as follows: ---------------------------------------------------------------------------------------- Number of Unrealized Contracts Settlement Appreciation/ Type Long/(Short) Month Value (Depreciation) ---------------------------------------------------------------------------------------- F/C 90 Day Euro Future (26) 12/16 $(6,370,325) $ (5,363) U.S. 5 Year Note (11) 3/14 (1,329,969) (3,000) F/C S&P 500 (14) 6/14 (1,295,420) (8,540) ---------------------------------------------------------------------------------------- $ (16,903) ======================================================================================== D. Forward Foreign Currency Contracts The Fund may enter into forward foreign currency contracts (contracts) for the purchase or sale of a specific foreign currency at a fixed price on a future date. All contracts are marked to market daily at the applicable exchange rates, and any resulting unrealized appreciation or depreciation is recorded in the Fund's financial statements. The Fund records realized gains and losses at the time a contract is offset by entry into a closing transaction or extinguished by delivery of the currency. Risks may arise upon entering into these contracts from the potential inability of counterparties to meet the terms of the contract and from unanticipated movements in the value of foreign currencies relative to the U.S. dollar (see Note 6). E. Federal Income Taxes It is the Fund's policy to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its taxable income and net realized capital gains, if any, to its Pioneer Long/Short Opportunistic Credit Fund | Semiannual Report | 2/28/14 37 shareowners. Therefore, no federal income tax provision is required. As of February 28, 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. 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 February 28, 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. 38 Pioneer Long/Short Opportunistic Credit Fund | Semiannual Report | 2/28/14 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 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. Pioneer Long/Short Opportunistic Credit Fund | Semiannual Report | 2/28/14 39 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 February 28, 2014 are listed in the Schedule of Investments. The average value of credit default swap contracts open during the period ended February 28, 2014 was $8,086,928. 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. For the period ended February 28, 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 February 28, 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 $8,616 in management fees, administrative costs and certain other reimbursements payable to PIM at February 28, 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. 40 Pioneer Long/Short Opportunistic Credit Fund | Semiannual Report | 2/28/14 In addition, the Fund reimburses PIMSS for out-of-pocket expense 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 February 28, 2014, there were no out-of-pocket expenses, transfer agent fees and out-of-pocket reimbursements payable. 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 $572 in distribution fees payable to PFD at February 28, 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.

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 period ended February 28, 2014, the Fund's expenses were not reduced under such arrangements. 7. 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 Eurodollar rate on the borrowing date. The Funds pay an annual commitment to participate in a credit facility. The commitment fee is allocated among participating Funds based on an allocation schedule set forth in the credit agreement. For the period ended February 28, 2014, the Fund had no borrowings under the credit facility. 8.

(PIM) serves as the investment adviser to Pioneer Long/Short Opportunistic Credit Fund (the Fund) pursuant to an investment advisory agreement between PIM and the Fund. Based on their evaluation of the information provided by PIM, the Trustees, including the Independent Trustees voting separately, unanimously approved an investment advisory agreement for the Fund. In considering the investment advisory agreement, the Trustees considered various factors that they determined were relevant, including the factors described below. In all quintile rankings referred to throughout this disclosure, the first quintile is most favorable to Fund shareowners. The Trustees did not identify any single factor as the controlling factor in determining to approve the agreement. Nature, Extent and Quality of Services The Trustees considered the nature, extent and quality of the services that would be provided by PIM to the Fund under the investment advisory agreement. The Trustees reviewed PIM's investment approach for the Fund and its research process, and considered the resources of PIM and the personnel of PIM who would provide investment management services to the Fund. The Trustees also considered that, as administrator, PIM would be responsible for the administration of the Fund's business and other affairs. The Trustees considered the quality of such services provided by PIM to the other Pioneer Funds. The Trustees considered the fees to be paid to PIM for the provision of administration services. Based on these considerations, the Trustees concluded that the nature, extent and quality of services that PIM would provide to the Fund were satisfactory and consistent with the terms of the investment advisory agreement. Performance of the Fund The Trustees did not consider the Fund's performance in approving the investment advisory agreement because the Fund was newly-offered and did not have a performance history. Management Fee and Expenses The Trustees considered information compiled by Strategic Insight Simfund, an independent third party, to compare the Fund's proposed management fee and anticipated expense ratio with a peer group of funds included in the Morningstar Non-Traditional Bond category. The Trustees considered that the Fund's proposed management fee would rank in the fifth quintile of the peer group, and just over the median management fee of a subset of the peer group 46 Pioneer Long/Short Opportunistic Credit Fund | Semiannual Report | 2/28/14 consisting of funds that pursue an investment approach similar to the Fund's investment approach. The Trustees considered factors distinguishing the Fund from the funds in the peer group. The Trustees also considered that, taking into account the contractual expense limitation agreed to by PIM with respect to the Fund, the Fund's anticipated expense ratio would rank in the fifth quintile of the peer group, and in the third quintile of the subset of the peer group that pursue an investment approach similar to the Fund's investment approach. The Trustees concluded that the proposed management fee payable by the Fund to PIM was reasonable in relation to the nature and quality of services to be provided by PIM. Profitability The Trustees did not consider PIM's profitability with respect to the management of the Fund in approving the investment advisory agreement because the Fund was newly-offered and profitability information was not available. Economies of Scale The Trustees considered PIM's views relating to economies of scale in connection with the Pioneer Funds as fund assets grow and the extent to which any such economies of scale are shared with funds and fund shareholders. The Trustees concluded that economies of scale, if any, would be appropriately shared with the Fund. Other Benefits The Trustees considered the other potential benefits to PIM from its relationship with the Fund, including the character and amount of fees that would be paid by the Fund, other than under the investment advisory agreement, for services that would be provided by PIM and its affiliates, and the revenues and profitability of PIM's businesses other than the fund business. The Trustees concluded that the receipt of these benefits was reasonable in the context of the overall relationship between PIM and the Fund. Conclusion After consideration of the factors described above as well as other factors, the Trustees, including all of the independent Trustees, concluded that the investment advisory agreement between PIM and the Fund, including the fees payable thereunder, was fair and reasonable and voted to approve the investment advisory agreement for the Fund.

PIONEER FUNDS APPROVAL OF AUDIT, AUDIT-RELATED, TAX AND OTHER SERVICES PROVIDED BY THE INDEPENDENT AUDITOR SECTION I - POLICY PURPOSE AND APPLICABILITY The Pioneer Funds recognize the importance of maintaining the independence of their outside auditors. Maintaining independence is a shared responsibility involving Pioneer Investment Management, Inc ("PIM"), the audit committee and the independent auditors. The Funds recognize that a Fund's independent auditors: 1) possess knowledge of the Funds, 2) are able to incorporate certain services into the scope of the audit, thereby avoiding redundant work, cost and disruption of Fund personnel and processes, and 3) have expertise that has value to the Funds. As a result, there are situations where it is desirable to use the Fund's independent auditors for services in addition to the annual audit and where the potential for conflicts of interests are minimal. Consequently, this policy, which is intended to comply with Rule 210.2-01(C)(7), sets forth guidelines and procedures to be followed by the Funds when retaining the independent audit firm to perform audit, audit-related tax and other services under those circumstances, while also maintaining independence. Approval of a service in accordance with this policy for a Fund shall also constitute approval for any other Fund whose pre-approval is required pursuant to Rule 210.2-01(c)(7)(ii). In addition to the procedures set forth in this policy, any non-audit services that may be provided consistently with Rule 210.2-01 may be approved by the Audit Committee itself and any pre-approval that may be waived in accordance with Rule 210.2-01(c)(7)(i)(C) is hereby waived. Selection of a Fund's independent auditors and their compensation shall be determined by the Audit Committee and shall not be subject to this policy.
