This is a welcome relief, and we are generally optimistic about the prospects for the economy going forward. Still, challenges remain. Unemployment is high; consumer demand and loan growth are weak; and housing has not returned to normal. At Pioneer, we have long advocated the benefits of investing for the long term. This strategy has generally performed well for many investors. Those who remained invested in the market during the downturn have most likely seen their portfolios start to recover over the past year, as the Dow Jones Industrial Average climbed back from the depressed levels we saw in early 2009. Many bond investors have similarly seen a strong rebound, with a broad-based recovery occurring across many different fixed-income asset classes. The riskiest asset classes, such as high-yield bonds, outperformed other fixed-income asset classes during most of 2009. At Pioneer, we are not changing the approach to investing that we have used for more than 80 years. We remain focused on company fundamentals and risk management. Our investment process is based on careful research into individual companies, quantitative analysis, and active portfolio management. This three-pillared process, which we apply to each of our portfolios, is supported by an integrated team approach and is designed to carefully balance risk and reward. While we see potential opportunities for making money in many corners of the markets around the globe, it takes research and experience to separate solid investment opportunities from speculation. Following this difficult period, many investors are rethinking their approach to investing and risk management. Some are questioning whether the basic investment principles they were taught in the past are still useful in today's markets. Complicating matters is that financial markets remain unpredictable. Our advice, as always, is to work closely with a trusted financial advisor to discuss your goals and work together to develop an investment strategy that meets your individual needs. There is no single best strategy that works for every investor. 2 Pioneer Diversified High Income Trust | Annual Report | 4/30/10 We invite you to learn more about Pioneer and our time-tested approach to investing by consulting with your financial advisor or visiting us online at www.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 Diversified High Income Trust | Annual Report | 4/30/10 3 Portfolio Management Discussion | 4/30/10 Mounting evidence of strengthening economies, both domestic and foreign, led to a strong recovery in the prices of credit-sensitive securities during the 12 months ending April 30, 2010. Corporate high-yield bonds, bank loans and other securities carrying credit risk rebounded from depressed levels over the 12-month period as investors grew more confident in an economic recovery. In the following discussion, Andrew Feltus and Jonathan Sharkey discuss the factors that influenced the performance of Pioneer Diversified High Income Trust during the 12-month period ended April 30, 2010. Mr. Feltus and Mr. Sharkey are members of Pioneer's fixed-income team and leaders of the investment team responsible for the daily management of the Trust. Q How did the Trust perform during the 12 months ended April 30, 2010? A Pioneer Diversified High Income Trust performed very well, producing a total return of 62.09% at net asset value and 73.25% at market price, while the Trust's customized benchmark returned 36.26%. The Trust's customized benchmark is based on a 50% weighting of the Bank of America/Merrill Lynch Global High Yield and Emerging Markets Plus Index (BofA ML GHY-EMP Index), which gained 40.25% over the 12 month-period, and a 50% weighting of the CSFB Leveraged Loan Index, which gained 32.26%. On April 30, 2010, the Trust's distribution rate was 9.38%, based on the most recent monthly dividend and the market closing price on April 30, 2010, and its 30-day SEC yield was 9.21%. As of April 30, 2010, the Trust was selling at a premium of market price to net asset value of 1.4%. Q What were the principal factors that contributed to the Trust's performance over the 12 months ended April 30, 2010? A As confidence in an economic resurgence returned to the capital markets, domestic high-yield bonds and floating-rate bank loans sharply recovered in price, delivering robust returns to investors. A rally that began in March of 2009 continued throughout the 12 months ended April 30, 2010, with only brief interruptions in momentum, as investors sought out opportunities to gain higher yields in securities that had been selling at depressed prices. The economy, as reflected by gross domestic product (GDP), began growing again and corporate profits began rising. Even unemployment, typically a lagging indicator of economic progress, appeared to begin to improve in the final months of the 12-month period. Throughout the 12 months, the Trust placed heavy emphasis on domestic high-yield bonds and bank loans, which comprised 34.7% and 24.9% of the Trust's total investment portfolio, respectively, as of April 30, 2010. 4 Pioneer Diversified High Income Trust | Annual Report | 4/30/10 The Trust had an additional 19.2% of its total investment portfolio in international high-yield and emerging market debt, and a small, but growing allocation to non-government agency mortgage-backed securities. For diversification, the Trust also had 14.9% of its total investment portfolio invested in floating-rate, catastrophe-linked insurance bonds. The strong returns achieved by the Trust's investments were amplified by the Trust's increased use of borrowed funds, or leverage. Improved conditions in the credit markets allowed the Trust to refinance its debt and enter a new loan agreement that effectively reduced the cost of borrowing. The Trust was able to redeploy the borrowed funds into the rising market. Leverage represented approximately 29% of the Trust's total assets. Q How did the Trust's investment strategy affect performance over the 12 months ended April 30, 2010? A High-yield corporate bonds and emerging market debt produced particularly strong returns during the period, and the Trust's positioning in both sectors contributed substantially to the solid returns. Floating-rate bank loans, while trailing the high-yield sector, also delivered healthy returns. Relative to the BofA ML GHY-EMP Index, the Trust was substantially underweighted in Europe and in investments denominated in the euro currency; that positioning helped when government debt problems in Europe, most notably in Greece, pressured European investments. While 17% of the BofA ML GHY-EMP Index was represented by the euro bloc, the Trust had just 3.7% of its total investment portfolio allocated to the euro bloc and other European currencies, and part of that was invested in Norwegian currency, which proved more resilient than the euro. During the 12-month period, we began adding to the Trust's investments in catastrophe-linked, re-insurance bonds. While those bonds underperformed high-yield corporates and bank loans, they offered the Trust diversification protection and the advantages of floating-rate yields, which should offer the potential for higher income when interest rates eventually start rising. We also began adding non-agency mortgage-backed securities to the Trust's portfolio, as they appeared to be selling at attractive relative values and also offered the advantages of floating rates. At the end of the period, more than 50% of the Trust's total investment portfolio was held in floating-rate securities. Q What types of individual investments most influenced the Trust's performance results during the 12 months ended April 30, 2010? A Security selection in the Trust's investments in both high-yield bonds and bank loans was very good. Among bonds of capital goods companies, two standouts were: Lear, a manufacturer of components for the automotive industry that was reorganized after filing for bankruptcy; and Commercial Pioneer Diversified High Income Trust | Annual Report | 4/30/10 5 Vehicle Group, a manufacturer of parts for the truck industry. In the materials sector, Noranda, a U.S. aluminum producer, did very well. Among the Trust's bond holdings in the financial sector, there were excellent results from investments in securities of Wells Fargo, PNC Financial, and investment bank Goldman Sachs. In the emerging markets, bond holdings of Minerva and Grupo Bertin, two Brazilian beef companies, appreciated significantly, supported by improving conditions in emerging markets, rising commodity prices and the appreciation in value of Brazil's currency. One disappointing investment for the Trust was Pegasystems, a software producer for the travel business that is undergoing a restructuring after defaulting on its bond in January of 2010. While almost all other high-yield bond investments performed positively, the Trust's investments in securities from the health care and utilities sectors -- two less cyclical groups -- tended to underperform the overall market. Among the Trust's bank loan holdings, a notable strong performer was the senior debt of Ceva Logistics, as the company strengthened its balance sheet. Two loans to an aviation service company, DAE Aviation & Standard Aero, also fared quite well. The firm benefited when the demand for aircraft maintenance services increased as the global economy recovered. One disappointing loan investment for the Trust, however, was the debt of Calpine, the giant energy company. The loan declined slightly in value after the company announced it would not be paying down its debt, contrary to market expectations. Q What is your investment outlook? A We believe the economic recovery will continue to advance in 2010, which should lead to growing corporate profits, which in turn should support the performance of both high-yield corporate bonds and floating-rate bank loans. At this point, it is difficult to anticipate the investment environment in 2011, however, as the market will be reacting to anticipated tax increases included as embodied in the phase-in of national health care reform legislation, as well as tighter monetary policy in China and tighter fiscal policy in Europe. In the near term, economic fundamentals look healthy. In the high-yield market, bond prices still appear attractive, especially after a market pullback shortly after the end of the Trust's 12-month reporting period. Looking forward, we expect that as the economy continues to recover, interest rates will start rising. We plan to position the Trust's portfolio for this eventuality by increasing investments in floating-rate securities, including bank loans, event-linked insurance bonds, and non-government agency mortgage-backed securities -- all of which have the ability to increase the Trust's income as yields rise. 6 Pioneer Diversified High Income Trust | Annual Report | 4/30/10 In general, we do not anticipate a repeat of the robust returns delivered in the past year. As we look to the future, we think fundamental analysis and individual security selection should be increasingly important elements in achieving good performance. We think this type of market plays to Pioneer's long-term strengths in credit research and analysis. Please refer to the Schedule of Investments on pages 11-38 for a full listing of Trust securities. Investments in high-yield or lower-rated securities are subject to greater-than-average risk. The Trust may invest in securities of issuers that are in default or that are in bankruptcy. Investing in foreign and/or emerging markets securities involves risks relating to interest rates, currency exchange rates, economic, and political conditions. When interest rates rise, the prices of debt securities in the Trust will generally fall. Conversely, when interest rates fall the prices of debt securities in the Trust generally will rise. Investments in the Trust are subject to possible loss due to the financial failure of the issuers of the underlying securities and their inability to meet their debt obligations. The Trust may invest significantly in illiquid securities. Illiquid securities may be difficult to dispose of at a fair price at the times when the Trust believes it is desirable to do so and their market price is generally more volatile than that of more liquid securities. Illiquid securities also are more difficult to value, and investment of the Trust's assets in illiquid securities may restrict the Trust's ability to take advantage of market opportunities. The Trust is authorized to borrow from banks and issue debt securities, which are forms of leverage. Leverage creates significant risks, including the risk that the Trust's income or capital appreciation will not be sufficient to cover the cost of leverage, which may adversely affect the return for the holders of common shares. Risks of investing in the Trust are discussed in greater detail in the Trust's original offering prospectus and in shareowner reports from time to time. Past performance is no guarantee of future results, and there is no guarantee that market forecasts discussed will be realized. Any information in this shareowner report regarding market or economic trends or the factors influencing the Trust's historical or future performance are statements of the opinion of Trust management as of the date of this report. These statements should not be relied upon for any other purposes.

Current performance may be lower or higher than the performance data quoted. Performance data shown represents past performance. Past performance is no guarantee of future results. Investment return and market price will fluctuate, and your shares may trade below net asset value (NAV) due to such factors as interest rate changes and the perceived credit quality of borrowers. Total investment return does not reflect broker sales charges or commissions. All performance is for common shares of the Trust. Closed-end funds, unlike open-end funds, are not continuously offered. There is a one-time public offering and, once issued, shares of closed-end funds are sold in the open market through a stock exchange and frequently trade at prices lower than their NAV. NAV per common share is total assets less total liabilities, which includes bank borrowing, divided by the number of common shares outstanding. When NAV is lower than market price, dividends are assumed to be reinvested at the greater of NAV or 95% of the market price. When NAV is higher, dividends are assumed to be reinvested at prices obtained under the Trust's dividend reinvestment plan. The performance table and graph do not reflect the deduction of fees and taxes that a shareowner would pay on Trust distributions. The Bank of America/Merrill Lynch Global High Yield and Emerging Markets Plus Index tracks the performance of the below- and border-line investment-grade global debt markets denominated in the major developed market currencies. The Index includes sovereign issuers rated BBB1 and lower along with corporate issues rated BB1 and lower. There are no restrictions on issuer country of domicile. The CSFB Leveraged Loan Index is designed to mirror the investible universe of the U.S. dollar-denominated leveraged loan market. The CSFB Leveraged Loan Index consists of tradable term loans with at least one year to maturity and rated BBB or lower. Index returns are calculated monthly, assume reinvestment of dividends and, unlike Trust returns, do not reflect any fees, expenses or sales charges. The indices are not leveraged.

The accompanying notes are an integral part of these financial statements. Pioneer Diversified High Income Trust | Annual Report | 4/30/10 43 Notes to Financial Statements | 4/30/10 1. Organization and Significant Accounting Policies Pioneer Diversified High Income Trust (the Trust) was organized as a Delaware statutory trust on January 30, 2007. Prior to commencing operations on May 30, 2007, the Trust had no operations other than matters relating to its organization and registration as a diversified, closed-end management investment company under the Investment Company Act of 1940, as amended. The investment objective of the Trust is to provide a high level of current income and, as a secondary objective, the Trust may seek capital appreciation to the extent that it is consistent with its investment objective. Information regarding the Trust's principal risks is contained in the Trust's original offering prospectus, with additional information included in the Trust's shareowner reports from time to time. Please refer to those documents when considering the Trust's risks. At times, the Trust's investments may represent industries or industry sectors that are interrelated or have common risks, making it more susceptible to any economic, political, or regulatory developments or other risks affecting those industries and sectors. The Trust invests in below investment grade (high yield) debt securities, floating rate loans and event-linked bonds sometimes referred to as "catastrophe" bonds or "insurance-linked" bonds. The Trust may invest in securities and other obligations of any credit quality, including those that are rated below investment grade, or are unrated but are determined by the investment adviser to be of equivalent credit quality. Below investment grade securities are commonly referred to as "junk bonds" and are considered speculative with respect to the issuer's capacity to pay interest and repay principal. These securities involve greater risk of loss, are subject to greater price volatility, and are less liquid, especially during periods of economic uncertainty or change, than higher rated debt securities. The Trust may invest in securities of issuers that are in default or that are in bankruptcy. The Trust's investments in certain foreign markets or countries with limited developing markets may subject the Trust to a greater degree of risk than in a developed market. These risks include disruptive political or economic conditions and the possible imposition of adverse governmental laws or currency exchange restrictions. The Trust's financial statements have been prepared in conformity with U.S. generally accepted accounting principles that require the management of the Trust 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 44 Pioneer Diversified High Income Trust | Annual Report | 4/30/10 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 Trust in preparation of its financial statements, which are consistent with those generally accepted in the investment company industry: A. Security Valuation Security transactions are recorded as of trade date. The net asset value of the Trust 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. Investments in loan interests 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. For the limited number of loan interests for which no reliable price quotes are available, such loan interests will be valued by Loan Pricing Corporation through the use of pricing matrices to determine valuations. Fixed income securities with remaining maturity of more than sixty days are valued at prices supplied by independent pricing services, which consider such factors as market prices, market events, quotations from one or more brokers, Treasury spreads, yields, maturities and ratings. Valuations may be supplemented by dealers and other sources, as required. Equity securities are valued at the last sale price on the principal exchange where they are traded. Securities or loans for which market prices and/or quotations are not readily available or are considered to be unreliable are valued using fair value methods pursuant to procedures adopted by the Board of Trustees. The Trust may use the fair value methods if it is determined that a significant event has occurred after the close of the exchange or market on which the security trades and prior to the determination of the Trust's net asset value. Thus, the valuation of the Trust's securities may differ from exchange prices. At April 30, 2010, 7 securities were valued using fair value methods (other than securities valued using prices supplied by independent pricing services) representing 0.9% of net assets. Inputs used in the valuation of a security using fair value methods include credit ratings, the financial condition of the company, current market conditions and comparable securities. Short-term income securities with remaining maturities of sixty days or less generally are valued at amortized cost. Money market mutual funds are valued at net asset value. Discounts and premiums on debt securities are accreted or amortized, respectively, daily, into interest income on an effective yield to maturity basis with a corresponding increase or decrease in the cost basis of the security. Premiums and discounts related to certain mortgage-backed securities are amortized or accreted in proportion to the monthly paydowns. Interest income, including income on interest bearing cash accounts, is recorded on Pioneer Diversified High Income Trust | Annual Report | 4/30/10 45 an accrual basis, net of unrecoverable foreign taxes withheld at the applicable country rates. 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 Trust becomes aware of the ex-dividend data in the exercise of reasonable diligence. 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 Trust are maintained in U.S. dollars. Amounts denominated in foreign currencies are translated into U.S. dollars using current exchange rates. Net realized gains and losses on foreign currency transactions, if any, represent, among other things, the net realized gains and losses on foreign currency contracts, disposition of foreign currencies and the difference between the amount of income accrued and the U.S. dollars actually received. Further, the effects of changes in foreign currency exchange rates on investments are not segregated in the Statement of Operations from the effects of changes in market prices of those securities but are included with the net realized and unrealized gain or loss on investments. C. Forward Foreign Currency Contracts The Trust may enter into forward foreign currency contracts (contracts) for the purchase or sale of a specific foreign currency at a fixed price on a future date. All contracts are marked to market daily at the applicable exchange rates, and any resulting unrealized gains or losses are recorded in the Trust's financial statements. The Trust records realized gains and losses at the time a portfolio hedge is offset by entry into a closing transaction or extinguished by delivery of the currency. Risks may arise upon entering into these contracts from the potential inability of counterparties to meet the terms of the contracts and from unanticipated movements in the value of foreign currencies relative to the U.S. dollar (see Note 5). D. Federal Income Taxes It is the Trust'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. Tax years for the prior two fiscal years remain subject to examination by tax authorities. The amounts and characterizations of distributions to shareowners for financial reporting purposes are determined in accordance with federal 46 Pioneer Diversified High Income Trust | Annual Report | 4/30/10 income tax rules. Therefore, the sources of the Trust's distributions may be shown in the accompanying financial statements as either from or in excess of net investment income or net realized gain (loss) on investment and foreign currency transactions, or from paid-in capital, depending on the type of book/tax differences that may exist. At April 30, 2010, the Trust reclassified $158,601 to decrease distributions in excess of net investment income and to increase net realized loss on investments to reflect permanent book/tax differences. The reclassification has no impact on the net assets of the Trust and presents the Trust's capital accounts on a tax basis. At April 30, 2010, the Trust had a net capital loss carryforward of $22,593,756 of which the following amounts will expire between 2016 and 2018 if not utilized: $231,744 in 2016, $413,150 in 2017 and $21,948,862 in 2018. The Trust has elected to defer approximately $2,026,829 of capital losses recognized between November 1, 2009 and April 30, 2010 to its fiscal year ending April 30, 2011. The tax character of distributions paid to shareowners during the years ended April 30, 2010 and April 30, 2009 was as follows: --------------------------------------------------------- 2010 2009 --------------------------------------------------------- Distributions paid from: Ordinary income $13,800,249 $20,135,595 Tax return of capital 2,651,977 371,077 --------------------------------------------------------- Total $16,452,226 $20,506,672 ========================================================= The following shows the components of distributable earnings (loss) on a federal income tax basis at April 30, 2009. ----------------------------------------------- ----------------------------------------------- Distributable earnings: Capital loss carryforward $ (22,593,756) Post-October loss deferred (2,026,829) Dividends payable (1,311,235) Unrealized depreciation (696,999) ----------------------------------------------- Total $ (26,628,819) =============================================== The difference between book-basis and tax-basis unrealized depreciation is primarily attributable to the tax deferral of losses on wash sales, the realization for tax purposes of unrealized gains on investments in passive foreign investment companies, the book/tax differences in the accrual of income on securities in default, the difference between book and tax amortization Pioneer Diversified High Income Trust | Annual Report | 4/30/10 47 methods for premiums and discounts on fixed income securities and other book/tax temporary differences. E. Repurchase Agreements With respect to repurchase agreements entered into by the Trust, the value of the underlying securities (collateral), including accrued interest is required to be equal to or in excess of the repurchase price. The collateral for all repurchase agreements is held in safekeeping in the customer-only account of the Trust's custodian or sub custodians of the Trust. The Trust's investment adviser, Pioneer Investment Management, Inc. (PIM), is responsible for determining that the value of the collateral remains at least equal to the repurchase price F. Securities Lending The Trust lends securities in its portfolio to certain broker-dealers or other institutional investors. When entering into a securities loan transaction, the Trust typically receives cash collateral from the borrower equal to at least the fair value of the securities loaned, which is invested in temporary investments. Credit Suisse AG, New York Branch, as the Trust's securities lending agent, manages the Trust's securities lending collateral. The income earned on the investment of collateral is shared with the borrower and the lending agent in payment of any rebate due to the borrower with respect to the securities loan, and in compensation for the lending agent's services to the Trust. The Trust also continues to receive payments in lieu of dividends or interest on the securities loaned. Gain or loss on the fair value of the loaned securities that may occur during the term of the loan will be for the account of the Trust. The amount of the collateral is required to be adjusted daily to reflect any price fluctuation in the fair value of the loaned securities. If the required fair value of the collateral is less than the fair value of the loaned securities, the borrower is required to deliver additional collateral for the account of the Trust prior to the close of the next business day. The Trust has the right, under the lending agreement, to terminate the loan and recover the securities from the borrower with prior notice. The Trust is required to return the cash collateral to the borrower and could suffer a loss if the fair value of the collateral, as invested, has declined. G. Automatic Dividend Reinvestment Plan All common shareowners whose shares are registered in their own names automatically participate in the Automatic Dividend Reinvestment Plan (the Plan), under which participants receive all dividends and capital gain distributions (collectively, dividends) in full and fractional common shares of the Trust in lieu of cash. Shareowners may elect not to participate in the Plan. Shareowners not participating in the Plan receive all dividends and capital gain distributions in cash. Participation in the Plan is completely voluntary 48 Pioneer Diversified High Income Trust | Annual Report | 4/30/10 and may be terminated or resumed at any time without penalty by notifying American Stock Transfer & Trust Company, the agent for shareowners in administering the Plan (the Plan Agent), in writing prior to any dividend record date; otherwise such termination or resumption will be effective with respect to any subsequently declared dividend or other distribution. If a shareowner's shares are held in the name of a brokerage firm, bank or other nominee, the shareowner can ask the firm or nominee to participate in the Plan on the shareowner's behalf. If the firm or nominee does not offer the Plan, dividends will be paid in cash to the shareowner of record. A firm or nominee may reinvest a shareowner's cash dividend in common shares of the Trust on terms that differ from the terms of the Plan. Whenever the Trust declares a dividend on common shares payable in cash, participants in the Plan will receive the equivalent in common shares acquired by the Plan Agent either (i) through receipt of additional unissued but authorized common shares from the Trust or (ii) by purchase of outstanding common shares on the NYSE Amex or elsewhere. If, on the payment date for any dividend, the net asset value per common share is equal to or less than the market price per share plus estimated brokerage trading fees (market premium), the Plan Agent will invest the dividend amount in newly issued common shares. The number of newly issued common shares to be credited to each account will be determined by dividing the dollar amount of the dividend by the net asset value per common share on the date the shares are issued, provided that the maximum discount from the then current market price per share on the date of issuance does not exceed 5%. If, on the payment date for any dividend, the net asset value per common share is greater than the market value (market discount), the Plan Agent will invest the dividend amount in common shares acquired in open-market purchases. There are no brokerage charges with respect to newly issued common shares. However, each participant will pay a pro rata share of brokerage trading fees incurred with respect to the Plan Agent's open-market purchases. Participating in the Plan does not relieve shareowners from any federal, state or local taxes which may be due on dividends paid in any taxable year. Shareowners holding Plan shares in a brokerage account may not be able to transfer the shares to another broker and continue to participate in the Plan. 2. Management Agreement PIM, a wholly owned indirect subsidiary of UniCredit S.p.A. (UniCredit) manages the Trust's portfolio. Management fees payable under the Trust's Advisory Agreement with PIM are calculated daily at the annual rate of 0.85% of the Trust's average daily managed assets. "Managed assets" means (a) the total assets of the Trust, including any form of investment leverage, minus (b) all accrued liabilities incurred in the normal course of operations, which shall Pioneer Diversified High Income Trust | Annual Report | 4/30/10 49 not include any liabilities or obligations attributable to investment leverage obtained through (i) indebtedness of any type (including, without limitation, borrowing through a credit facility or the issuance of debt securities), (ii) the issuance of preferred stock or other similar preference securities, and/or (iii) any other means. For the year ended April 30, 2010, the net management fee (excluding waivers and reimbursements) was equivalent to 0.85% of the Trust's average daily managed assets, which was equivalent to 1.17% of the Trust's average daily net assets. In addition, under PIM's management and administration agreements, certain other services and costs are paid by PIM and reimbursed by the Trust. At April 30, 2010, $160,247 was payable to PIM related to management costs, administrative costs and certain other services and it is included in "Due to affiliates" on the Statement of Assets and Liabilities. PIM has retained Princeton Administrators, LLC (Princeton) to provide certain administrative and accounting services to the Trust on its behalf. PIM pays Princeton a monthly fee at an annual rate equal to 0.07% of the Trust's average daily managed assets up to $500 million and 0.03% of average daily managed assets in excess of $500 million, subject to a minimum monthly fee of $10,000. Princeton receives no compensation directly from the Trust. Effective September 30, 2010, Princeton has notified PIM that it will resign as administrators of the Trust. PIM has entered into a Research Services Agreement with Montpelier Capital Advisors, Ltd. (Montpelier). Under the research services agreement, Montpelier will provide research services to PIM with regard to event-linked bonds. PIM pays Montpelier a flat fee of $325,000 annually. Montpelier received no compensation directly from the Trust. Also, PIM had agreed for the first three years of the Trust's investment operations to limit the Trust's total annual expenses, excluding offering costs for common shares, interest expense, the cost of defending or prosecuting any claim or litigation to which the Trust is a party (together with any amount in judgment or settlement), indemnification expense or taxes incurred due to the failure of the Trust to qualify as a regulated investment company under the Code or any other non-recurring or non-operating expenses, to 0.90% of the Trust's average daily managed assets in year one, 0.95% of the Trust's average daily managed assets in year two and 1.00% of the Trust's average daily managed assets in year three. This is a contractual limit and may not be terminated by the adviser during the three year period which will terminate on May 30, 2010. For the year ended April 30, 2010 the expense reduction under such arrangement was $320,918. 50 Pioneer Diversified High Income Trust | Annual Report | 4/30/10 3. Transfer Agents Pioneer Investment Management Shareholder Services, Inc. (PIMSS), a wholly owned indirect subsidiary of UniCredit, through a sub-transfer agency agreement with American Stock Transfer & Trust Company, provides substantially all transfer agent and shareowner services related to the Trust at negotiated rates. In addition, the Trust reimburses PIMSS for out-of-pocket expenses incurred by PIMSS related to shareowner communications activities such as proxy and statement mailings and outgoing phone calls. 4. Expense Offset Arrangements The Trust has entered into an arrangement with its custodian whereby credits realized as a result of uninvested cash balances are used to reduce a portion of the Trust's custodian expenses. For the year ended April 30, 2010, the Trust expenses were reduced by $5 under such arrangement. 5. Forward Foreign Currency Contracts During the year ended April 30, 2010, the Trust had entered into various contracts that obligate the Trust 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 Trust may close out such contract by entering into an offsetting hedge contract. The average number of contracts open during the year ended April 30, 2010 was 2,421,667. As of April 30, 2010, the Trust had no outstanding portfolio hedges and no forward currency settlement contracts. 6. Loan Agreement Effective February 6, 2010, the Trust amended an existing $80,000,000 Revolving Credit Facility (the Credit Agreement) with the Bank of Nova Scotia. At April 30, 2010, the Trust had a borrowing outstanding under the Credit Agreement totaling $67,000,000. The interest rate charged at April 30, 2010 was 1.399%. During year ended April 30, 2010, the average daily balance was $54,528,767 at a weighted average interest rate of 2.20%. With respect to the loan, interest expense of $1,218,945 is included in the Statement of Operations. The Trust is required to maintain 300% asset coverage with respect to amounts outstanding under the Credit Agreement. Asset coverage is calculated by subtracting the Trust's total liabilities, not including any bank loans and senior securities, from the Trust's total assets and dividing such amount by the principal amount of the borrowings outstanding. As of the date indicated below, the Trust's debt outstanding and asset coverage were as follows: Pioneer Diversified High Income Trust | Annual Report | 4/30/10 51 ------------------------------------------- Total Asset coverage Amount per $1,000 of Date Outstanding Indebtedness ------------------------------------------- 4/30/10 $67,000,000 $3,467 7.

These financial statements and financial highlights are the responsibility of the Trust's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. We were not engaged to perform an audit of the Trust's internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Trust's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements and financial highlights, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of April 30, 2010, by correspondence with the custodian, agent banks, and brokers or by other appropriate auditing procedures where replies from brokers were not received. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of Pioneer Diversified High Income Trust at April 30, 2010, the results of its operations and its cash flows for the year then ended, the changes in its net assets for each of the two years in the period then ended and the financial highlights for each of the periods indicated therein, in conformity with U.S. generally accepted accounting principles. /s/ Ernst & Young LLP Boston, Massachusetts June 22, 2010 Pioneer Diversified High Income Trust | Annual Report | 4/30/10 53 ADDITIONAL INFORMATION (unaudited) During the period, there have been no material changes in the Trust's investment objective or fundamental policies that have not been approved by the shareowners.

Pioneer Diversified High Income Trust | Annual Report | 4/30/10 55 Approval of Investment Advisory Agreement (unaudited) Pioneer Investment Management, Inc. (PIM) serves as the investment adviser to Pioneer Diversified High Income Trust (the Trust) pursuant to an investment advisory agreement between PIM and the Trust. In order for PIM to remain the investment adviser of the Trust, the Trustees of the Trust must determine annually whether to renew the investment advisory agreement for the Trust. The contract review process began in March 2009 as the Trustees of the Trust agreed on, among other things, an overall approach and timeline for the process. In July 2009, 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 August 2009. After reviewing and discussing the materials, the Trustees submitted a request for additional information to PIM in September 2009, and materials were provided in response to this request. Meetings of the independent Trustees of the Trust were held in July, September, October, and November, 2009 to review and discuss the contract review materials. In addition, the Trustees took into account the information related to the Trust provided to the Trustees at each regularly scheduled meeting. At a meeting held on November 10, 2009, based on their evaluation of the information provided by PIM and third parties, the Trustees of the Trust, 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. 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 Trust, taking into account the investment objective and strategy of the Trust. The Trustees reviewed the terms of the investment advisory agreement. The Trustees also reviewed PIM's investment approach for the Trust, its research process and its process for trade execution. The Trustees considered the resources of PIM and the personnel of PIM who provide investment management services to the Trust. The Trustees considered the non-investment resources and personnel of PIM involved in PIM's services to the Trust, including PIM's compliance and legal resources and personnel. The Trustees also considered the substantial attention and high priority given by PIM's senior management to the Pioneer fund complex. 56 Pioneer Diversified High Income Trust | Annual Report | 4/30/10 The Trustees considered that PIM supervises and monitors the performance of the Trust's service providers and provides the Trust with personnel (including Trust officers) and other resources that are necessary for the Trust's business management and operations. The Trustees also considered that, as administrator, PIM is responsible for the administration of the Trust'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 Trust were satisfactory and consistent with the terms of the investment advisory agreement. Performance of the Trust The Trustees considered the performance results of the Trust over various time periods. They reviewed information comparing the Trust'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 Trust's benchmark index. The Trustees considered that the Trust's annualized total return was in the second quintile of its Morningstar category for the one year period ended June 30, 2009. (In all quintile rankings referred to throughout this disclosure, first quintile is most favorable to the Trust's shareowners. Thus, highest relative performance would be first quintile and lowest relative expenses would also be first quintile.) The Trustees considered that the Trust's yield (at market value) was better than the average yield (at market value) of the funds in its peer group as of June 30, 2009. The Trustees noted that the yield of the Trust also compared favorably to the blended yield of the Trust's primary and secondary benchmarks as of June 30, 2009. The Trustees reviewed data provided by Pioneer showing how leverage had benefited the Trust's common shareholders. The Trustees concluded that the investment performance of the Trust was satisfactory. Management Fee and Expenses The Trustees considered information on the fees and expenses of the Trust in comparison to the management fees and 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 Trust's management fee rate based on net assets attributable to common shares for the twelve months ended June 30, 2009 was in the fifth quintile relative to the management fees paid by other funds in its Strategic Insight peer group for the comparable period. The Trustees noted that the Trust has not issued preferred shares, but did have debt outstanding, and considered the effect of leverage on the Trust's management fee relative to its peers by reviewing the management fee ratios of the Trust and its peers based on managed assets rather than net assets attributable to common Pioneer Diversified High Income Trust | Annual Report | 4/30/10 57 shares. The Trustees also noted that the Trust is a specialized fund, and that additional skills and research are required in order to implement the Trust's investment strategy. The Trustees also considered that the Trust's expense ratio based on net assets attributable to common shares for the twelve months ended June 30, 2009 was in the fourth quintile relative to its Strategic Insight peer group for the comparable period. The Trustees considered the effect of leverage on the Trust's expense ratio relative to its peers by reviewing such expense ratios based on managed assets rather than net assets attributable to common shares. The Trustees noted the impact of the Trust's higher relative management fee on its expense ratio. The Trustees also considered the impact of leverage on the expense ratio of the Trust and its peers by reviewing such expense ratios without giving effect to interest expense (but acknowledging that auction agent fees were difficult to isolate and exclude). The Trustees also reviewed management fees charged by PIM to its institutional and other clients. In evaluating the fees associated with PIM's client accounts, the Trustees took into account the respective demands, resources and complexity associated with the Trust and client accounts. The Trustees noted that in some instances the fee rates for those clients were lower than the management fee for the Trust and considered that, under the investment advisory agreement with the Trust, PIM performs additional services for the Trust that it does not provide to those other clients or services that are broader in scope, including oversight of the Trust's other service providers and activities related to compliance and the extensive regulatory and tax regimes to which the Trust is subject. The Trustees concluded that the management fee payable by the Trust to PIM was reasonable in relation to the nature and quality of the services provided by PIM. The Trustees also concluded that the Trust's expense ratio was reasonable taking into account the nature and quality of 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 Trust, including the methodology used by PIM in allocating certain of its costs to the management of the Trust. The Trustees also considered PIM's profit margin in connection with the overall operation of the Trust. 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 Trust 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 Trust was not unreasonable. 58 Pioneer Diversified High Income Trust | Annual Report | 4/30/10 Economies of Scale The Trustees considered the extent to which PIM may realize economies of scale or other efficiencies in managing and supporting the Trust. Since the Trust is a closed-end fund that has not raised additional capital, the Trustees concluded that economies of scale were not a relevant consideration in the renewal of the investment advisory agreement. Other Benefits The Trustees considered the other benefits to PIM from its relationship with the Trust. The Trustees considered the character and amount of fees paid by the Trust, 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 Trust 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 Trust. 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 Trust, including the fees payable thereunder, was fair and reasonable and voted to approve the proposed renewal of the investment advisory agreement for the Trust.

CODE OF ETHICS.

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.

Non-Audit Services Beginning with non-audit service contracts entered into on or after May 6, 2003, the effective date of the new SEC pre- approval rules, the Trust's audit committee is required to pre- approve services to affiliates defined by SEC rules to the extent that the services are determined to have a direct impact on the operations or financial reporting of the Trust. For the years ended April 30, 2010 and 2009, there were no services provided to an affiliate that required the Trust's audit committee pre-approval. (f) If greater than 50 percent, disclose the percentage of hours expended on the principal accountant's engagement to audit the registrant's financial statements for the most recent fiscal year that were attributed to work performed by persons other than the principal accountant's full-time, permanent employees.

The aggregate non-audit fees for the Trust and affiliates, as previously defined, totaled approximately $8,290 in 2010 and $8,290 in 2009. (h) Disclose whether the registrant's audit committee of the board of trustees has considered whether the provision of non-audit services that were rendered to the registrant's investment adviser (not including any subadviser whose role is primarily portfolio management and is subcontracted with or overseen by another investment adviser), and any entity controlling, controlled by, or under common control with the investment adviser that provides ongoing services to the registrant that were not pre-approved pursuant to paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X is compatible with maintaining the principal accountant's independence. The Fund's audit committee of the Board of Trustees has considered whether the provision of non-audit services that were rendered to the Affiliates (as defined) that were not pre- approved pursuant to paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X is compatible with maintaining the principal accountant's independence. Item 5.

Included in Item 1 ITEM 7. DISCLOSURE OF PROXY VOTING POLICIES AND PROCEDURES FOR CLOSED-END MANAGEMENT INVESTMENT COMPANIES. A closed-end management investment company that is filing an annual report on this Form N-CSR must, unless it invests exclusively in non-voting securities, describe the policies and procedures that it uses to determine how to vote proxies relating to portfolio securities, including the procedures that the company uses when a vote presents a conflict between the interests of its shareholders, on the one hand, and those of the company's investment adviser; principal underwriter; or any affiliated person (as defined in Section 2(a)(3) of the Investment Company Act of 1940 (15 U.S.C. 80a-2(a)(3)) and the rules thereunder) of the company, its investment adviser, or its principal underwriter, on the other. Include any policies and procedures of the company's investment adviser, or any other third party, that the company uses, or that are used on the company's behalf, to determine how to vote proxies relating to portfolio securities. Proxy Voting Policies and Procedures of Pioneer Investment Management, Inc. VERSION DATED July, 2004 Overview Pioneer Investment Management, Inc. ("Pioneer") is a fiduciary that owes each of its client's duties of care and loyalty with respect to all services undertaken on the client's behalf, including proxy voting. When Pioneer has been delegated proxy-voting authority for a client, the duty of care requires Pioneer to monitor corporate events and to vote the proxies. To satisfy its duty of loyalty, Pioneer must place its client's interests ahead of its own and must cast proxy votes in a manner consistent with the best interest of its clients. Pioneer will vote all proxies presented in a timely manner. The Proxy Voting Policies and Procedures are designed to complement Pioneer's investment policies and procedures regarding its general responsibility to monitor the performance and/or corporate events of companies that are issuers of securities held in accounts managed by Pioneer. Pioneer's Proxy Voting Policies summarize Pioneer's position on a number of issues solicited by companies held by Pioneer's clients. The policies are guidelines that provide a general indication on how Pioneer would vote but do not include all potential voting scenarios. Pioneer's Proxy Voting Procedures detail monitoring of voting, exception votes, and review of conflicts of interest and ensure that case-by-case votes are handled within the context of the overall guidelines (i.e. best interest of client). The overriding goal is that all proxies for US and non-US companies that are received promptly will be voted in accordance with Pioneer's policies or specific client instructions. All shares in a company held by Pioneer-managed accounts will be voted alike, unless a client has given us specific voting instructions on an issue or has not delegated authority to us or the Proxy Voting Oversight Group determines that the circumstances justify a different approach. Pioneer does not delegate the authority to vote proxies relating to its clients to any of its affiliates, which include other subsidiaries of UniCredito. Any questions about these policies and procedures should be directed to the Proxy Coordinator. 1 Proxy Voting Procedures Proxy Voting Service Pioneer has engaged an independent proxy voting service to assist in the voting of proxies. The proxy voting service works with custodians to ensure that all proxy materials are received by the custodians and are processed in a timely fashion. To the extent applicable, the proxy voting service votes all proxies in accordance with the proxy voting policies established by Pioneer. The proxy voting service will refer proxy questions to the Proxy Coordinator (described below) for instructions under circumstances where: (1) the application of the proxy voting guidelines is unclear; (2) a particular proxy question is not covered by the guidelines; or (3) the guidelines call for specific instructions on a case-by-case basis. The proxy voting service is also requested to call to the Proxy Coordinator's attention specific proxy questions that, while governed by a guideline, appear to involve unusual or controversial issues. Pioneer reserves the right to attend a meeting in person and may do so when it determines that the company or the matters to be voted on at the meeting are strategically important to its clients. Proxy Coordinator Pioneer's Director of Investment Operations (the "Proxy Coordinator") coordinates the voting, procedures and reporting of proxies on behalf of Pioneer's clients. The Proxy Coordinator will deal directly with the proxy voting service and, in the case of proxy questions referred by the proxy voting service, will solicit voting recommendations and instructions from the Director of Portfolio Management US or, to the extent applicable, investment sub-advisers. The Proxy Coordinator is responsible for ensuring that these questions and referrals are responded to in a timely fashion and for transmitting appropriate voting instructions to the proxy voting service. The Proxy Coordinator is responsible for verifying with the Compliance Department whether Pioneer's voting power is subject to any limitations or guidelines issued by the client (or in the case of an employee benefit plan, the plan's trustee or other fiduciaries). Referral Items From time to time, the proxy voting service will refer proxy questions to the Proxy Coordinator that are described by Pioneer's policy as to be voted on a case-by-case basis, that are not covered by Pioneer's guidelines or where Pioneer's guidelines may be unclear with respect to the matter to be voted on. Under such certain circumstances, the Proxy Coordinator will seek a written voting recommendation from the Director of Portfolio Management US. Any such recommendation will include: (i) the manner in which the proxies should be voted; (ii) the rationale underlying any such decision; and (iii) the disclosure of any contacts or communications made between Pioneer and any outside parties concerning the proxy proposal prior to the time that the voting instructions are provided. In addition, the Proxy Coordinator will ask the Compliance Department to review the question for any actual or apparent conflicts of interest as described below under "Conflicts of 2 Interest." The Compliance Department will provide a "Conflicts of Interest Report," applying the criteria set forth below under "Conflicts of Interest," to the Proxy Coordinator summarizing the results of its review. In the absence of a conflict of interest, the Proxy Coordinator will vote in accordance with the recommendation of the Director of Portfolio Management US. If the matter presents a conflict of interest for Pioneer, then the Proxy Coordinator will refer the matter to the Proxy Voting Oversight Group for a decision. In general, when a conflict of interest is present, Pioneer will vote according to the recommendation of the Director of Portfolio Management US where such recommendation would go against Pioneer's interest or where the conflict is deemed to be immaterial. Pioneer will vote according to the recommendation of its proxy voting service when the conflict is deemed to be material and the Pioneer's internal vote recommendation would favor Pioneer's interest, unless a client specifically requests Pioneer to do otherwise. When making the final determination as to how to vote a proxy, the Proxy Voting Oversight Group will review the report from the Director of Portfolio Management US and the Conflicts of Interest Report issued by the Compliance Department. Conflicts of Interest A conflict of interest occurs when Pioneer's interests interfere, or appear to interfere with the interests of Pioneer's clients. Occasionally, Pioneer may have a conflict that can affect how its votes proxies. The conflict may be actual or perceived and may exist when the matter to be voted on concerns: o An affiliate of Pioneer, such as another company belonging to the UniCredito Italiano S.p.A. banking group (a "UniCredito Affiliate"); o An issuer of a security for which Pioneer acts as a sponsor, advisor, manager, custodian, distributor, underwriter, broker, or other similar capacity (including those securities specifically declared by PGAM to present a conflict of interest for Pioneer); o An issuer of a security for which UniCredito has informed Pioneer that a UniCredito Affiliate acts as a sponsor, advisor, manager, custodian, distributor, underwriter, broker, or other similar capacity; or o A person with whom Pioneer (or any of its affiliates) has an existing, material contract or business relationship that was not entered into in the ordinary course of Pioneer's business. o Pioneer will abstain from voting with respect to companies directly or indirectly owned by UniCredito Italiano Group, unless otherwise directed by a client. In addition, Pioneer will inform PGAM Global Compliance and the PGAM Independent Directors before exercising such rights. Any associate involved in the proxy voting process with knowledge of any apparent or actual conflict of interest must disclose such conflict to the Proxy Coordinator and the Compliance Department. The Compliance Department will review each item referred to Pioneer to determine whether an actual or potential conflict of interest with Pioneer exists in connection with the proposal(s) to be voted upon. The review will be conducted by comparing the apparent parties affected by the proxy proposal being 3 voted upon against the Compliance Department's internal list of interested persons and, for any matches found, evaluating the anticipated magnitude and possible probability of any conflict of interest being present. For each referral item, the determination regarding the presence or absence of any actual or potential conflict of interest will be documented in a Conflicts of Interest Report to the Proxy Coordinator. Securities Lending In conjunction with industry standards Proxies are not available to be voted when the shares are out on loan through either Pioneer's lending program or a client's managed security lending program. However, Pioneer will reserve the right to recall lent securities so that they may be voted according to the Pioneer's instructions. If a portfolio manager would like to vote a block of previously lent shares, the Proxy Coordinator will work with the portfolio manager and Investment Operations to recall the security, to the extent possible, to facilitate the vote on the entire block of shares. Share-Blocking "Share-blocking" is a market practice whereby shares are sent to a custodian (which may be different than the account custodian) for record keeping and voting at the general meeting. The shares are unavailable for sale or delivery until the end of the blocking period (typically the day after general meeting date). Pioneer will vote in those countries with "share-blocking." In the event a manager would like to sell a security with "share-blocking", the Proxy Coordinator will work with the Portfolio Manager and Investment Operations Department to recall the shares (as allowable within the market time-frame and practices) and/or communicate with executing brokerage firm. A list of countries with "share-blocking" is available from the Investment Operations Department upon request. Record Keeping The Proxy Coordinator shall ensure that Pioneer's proxy voting service: o Retains a copy of the proxy statement received (unless the proxy statement is available from the SEC's Electronic Data Gathering, Analysis, and Retrieval (EDGAR) system); o Retains a record of the vote cast; o Prepares Form N-PX for filing on behalf of each client that is a registered investment company; and o Is able to promptly provide Pioneer with a copy of the voting record upon its request. 4 The Proxy Coordinator shall ensure that for those votes that may require additional documentation (i.e. conflicts of interest, exception votes and case-by-case votes) the following records are maintained: o A record memorializing the basis for each referral vote cast; o A copy of any document created by Pioneer that was material in making the decision on how to vote the subject proxy; and o A copy of any conflict notice, conflict consent or any other written communication (including emails or other electronic communications) to or from the client (or in the case of an employee benefit plan, the plan's trustee or other fiduciaries) regarding the subject proxy vote cast by, or the vote recommendation of, Pioneer. o Pioneer shall maintain the above records in the client's file for a period not less than ten (10) years. Disclosure Pioneer shall take reasonable measures to inform its clients of the process or procedures clients must follow to obtain information regarding how Pioneer voted with respect to assets held in their accounts. In addition, Pioneer shall describe to clients its proxy voting policies and procedures and will furnish a copy of its proxy voting policies and procedures upon request. This information may be provided to clients through Pioneer's Form ADV (Part II) disclosure, by separate notice to the client, or through Pioneer's website. Proxy Voting Oversight Group The members of the Proxy Voting Oversight Group are Pioneer's: Director of Portfolio Management US, Head of Investment Operations, and Director of Compliance. Other members of Pioneer will be invited to attend meetings and otherwise participate as necessary. The Head of Investment Operations will chair the Proxy Voting Oversight Group. The Proxy Voting Oversight Group is responsible for developing, evaluating, and changing (when necessary) Pioneer's Proxy Voting Policies and Procedures. The group meets at least annually to evaluate and review these policies and procedures and the services of its third-party proxy voting service. In addition, the Proxy Voting Oversight Group will meet as necessary to vote on referral items and address other business as necessary. Amendments Pioneer may not amend its Proxy Voting Policies And Procedures without the prior approval of the Proxy Voting Oversight Group and its corporate parent, Pioneer Global Asset Management S.p.A 5 Proxy Voting Policies Pioneer's sole concern in voting proxies is the economic effect of the proposal on the value of portfolio holdings, considering both the short- and long-term impact. In many instances, Pioneer believes that supporting the company's strategy and voting "for" management's proposals builds portfolio value. In other cases, however, proposals set forth by management may have a negative effect on that value, while some shareholder proposals may hold the best prospects for enhancing it. Pioneer monitors developments in the proxy-voting arena and will revise this policy as needed. All proxies that are received promptly will be voted in accordance with the specific policies listed below. All shares in a company held by Pioneer-managed accounts will be voted alike, unless a client has given us specific voting instructions on an issue or has not delegated authority to us. Proxy voting issues will be reviewed by Pioneer's Proxy Voting Oversight Group, which consists of the Director of Portfolio Management US, the Director of Investment Operations (the Proxy Coordinator), and the Director of Compliance. Pioneer has established Proxy Voting Procedures for identifying and reviewing conflicts of interest that may arise in the voting of proxies. Clients may request, at any time, a report on proxy votes for securities held in their portfolios and Pioneer is happy to discuss our proxy votes with company management. Pioneer retains a proxy voting service to provide research on proxy issues and to process proxy votes. Administrative While administrative items appear infrequently in U.S. issuer proxies, they are quite common in non-U.S. proxies. We will generally support these and similar management proposals: o Corporate name change. o A change of corporate headquarters. o Stock exchange listing. o Establishment of time and place of annual meeting. o Adjournment or postponement of annual meeting. o Acceptance/approval of financial statements. o Approval of dividend payments, dividend reinvestment plans and other dividend-related proposals. o Approval of minutes and other formalities. 6 o Authorization of the transferring of reserves and allocation of income. o Amendments to authorized signatories. o Approval of accounting method changes or change in fiscal year-end. o Acceptance of labor agreements. o Appointment of internal auditors. Pioneer will vote on a case-by-case basis on other routine business; however, Pioneer will oppose any routine business proposal if insufficient information is presented in advance to allow Pioneer to judge the merit of the proposal. Pioneer has also instructed its proxy voting service to inform Pioneer of its analysis of any administrative items inconsistent, in its view, with supporting the value of Pioneer portfolio holdings so that Pioneer may consider and vote on those items on a case-by-case basis. Auditors We normally vote for proposals to: o Ratify the auditors. We will consider a vote against if we are concerned about the auditors' independence or their past work for the company. Specifically, we will oppose the ratification of auditors and withhold votes from audit committee members if non-audit fees paid by the company to the auditing firm exceed the sum of audit fees plus audit-related fees plus permissible tax fees according to the disclosure categories proposed by the Securities and Exchange Commission. o Restore shareholder rights to ratify the auditors. We will normally oppose proposals that require companies to: o Seek bids from other auditors. o Rotate auditing firms, except where the rotation is statutorily required or where rotation would demonstrably strengthen financial disclosure. o Indemnify auditors. o Prohibit auditors from engaging in non-audit services for the company. Board of Directors On issues related to the board of directors, Pioneer normally supports management. We will, however, consider a vote against management in instances where corporate performance has been very poor or where the board appears to lack independence. 7 General Board Issues Pioneer will vote for: o Audit, compensation and nominating committees composed of independent directors exclusively. o Indemnification for directors for actions taken in good faith in accordance with the business judgment rule. We will vote against proposals for broader indemnification. o Changes in board size that appear to have a legitimate business purpose and are not primarily for anti-takeover reasons. o Election of an honorary director. We will vote against: o Minimum stock ownership by directors. o Term limits for directors. Companies benefit from experienced directors, and shareholder control is better achieved through annual votes. o Requirements for union or special interest representation on the board. o Requirements to provide two candidates for each board seat. We will vote on a case-by case basis on these issues: o Separate chairman and CEO positions. We will consider voting with shareholders on these issues in cases of poor corporate performance. Elections of Directors In uncontested elections of directors we will vote against: o Individual directors with absenteeism above 25% without valid reason. We support proposals that require disclosure of director attendance. o Insider directors and affiliated outsiders who sit on the audit, compensation, stock option or nominating committees. For the purposes of our policy, we accept the definition of affiliated directors provided by our proxy voting service. We will also vote against: o Directors who have failed to act on a takeover offer where the majority of shareholders have tendered their shares. o Directors who appear to lack independence or are associated with very poor corporate performance. 8 We will vote on a case-by case basis on these issues: o Re-election of directors who have implemented or renewed a dead-hand or modified dead-hand poison pill (a "dead-hand poison pill" is a shareholder rights plan that may be altered only by incumbent or "dead " directors. These plans prevent a potential acquirer from disabling a poison pill by obtaining control of the board through a proxy vote). o Contested election of directors. o Prior to phase-in required by SEC, we would consider supporting election of a majority of independent directors in cases of poor performance. o Mandatory retirement policies. o Directors who have ignored a shareholder proposal that has been approved by shareholders for two consecutive years. Takeover-Related Measures Pioneer is generally opposed to proposals that may discourage takeover attempts. We believe that the potential for a takeover helps ensure that corporate performance remains high. Pioneer will vote for: o Cumulative voting. o Increase ability for shareholders to call special meetings. o Increase ability for shareholders to act by written consent. o Restrictions on the ability to make greenmail payments. o Submitting rights plans to shareholder vote. o Rescinding shareholder rights plans ("poison pills"). o Opting out of the following state takeover statutes: o Control share acquisition statutes, which deny large holders voting rights on holdings over a specified threshold. o Control share cash-out provisions, which require large holders to acquire shares from other holders. o Freeze-out provisions, which impose a waiting period on large holders before they can attempt to gain control. o Stakeholder laws, which permit directors to consider interests of non-shareholder constituencies. 9 o Disgorgement provisions, which require acquirers to disgorge profits on purchases made before gaining control. o Fair price provisions. o Authorization of shareholder rights plans. o Labor protection provisions. o Mandatory classified boards. We will vote on a case-by-case basis on the following issues: o Fair price provisions. We will vote against provisions requiring supermajority votes to approve takeovers. We will also consider voting against proposals that require a supermajority vote to repeal or amend the provision. Finally, we will consider the mechanism used to determine the fair price; we are generally opposed to complicated formulas or requirements to pay a premium. o Opting out of state takeover statutes regarding fair price provisions. We will use the criteria used for fair price provisions in general to determine our vote on this issue. o Proposals that allow shareholders to nominate directors. We will vote against: o Classified boards, except in the case of closed-end mutual funds. o Limiting shareholder ability to remove or appoint directors. We will support proposals to restore shareholder authority in this area. We will review on a case-by-case basis proposals that authorize the board to make interim appointments. o Classes of shares with unequal voting rights. o Supermajority vote requirements. o Severance packages ("golden" and "tin" parachutes). We will support proposals to put these packages to shareholder vote. o Reimbursement of dissident proxy solicitation expenses. While we ordinarily support measures that encourage takeover bids, we believe that management should have full control over corporate funds. o Extension of advance notice requirements for shareholder proposals. o Granting board authority normally retained by shareholders (e.g., amend charter, set board size). o Shareholder rights plans ("poison pills"). These plans generally allow shareholders to buy additional shares at a below-market price in the event of a change in control and may deter some bids. 10 Capital Structure Managements need considerable flexibility in determining the company's financial structure, and Pioneer normally supports managements' proposals in this area. We will, however, reject proposals that impose high barriers to potential takeovers. Pioneer will vote for: o Changes in par value. o Reverse splits, if accompanied by a reduction in number of shares. o Share repurchase programs, if all shareholders may participate on equal terms. o Bond issuance. o Increases in "ordinary" preferred stock. o Proposals to have blank-check common stock placements (other than shares issued in the normal course of business) submitted for shareholder approval. o Cancellation of company treasury shares. We will vote on a case-by-case basis on the following issues: o Reverse splits not accompanied by a reduction in number of shares, considering the risk of delisting. o Increase in authorized common stock. We will make a determination considering, among other factors: o Number of shares currently available for issuance; o Size of requested increase (we would normally approve increases of up to 100% of current authorization); o Proposed use of the additional shares; and o Potential consequences of a failure to increase the number of shares outstanding (e.g., delisting or bankruptcy). o Blank-check preferred. We will normally oppose issuance of a new class of blank-check preferred, but may approve an increase in a class already outstanding if the company has demonstrated that it uses this flexibility appropriately. o Proposals to submit private placements to shareholder vote. o Other financing plans. We will vote against preemptive rights that we believe limit a company's financing flexibility. 11 Compensation Pioneer supports compensation plans that link pay to shareholder returns and believes that management has the best understanding of the level of compensation needed to attract and retain qualified people. At the same time, stock-related compensation plans have a significant economic impact and a direct effect on the balance sheet. Therefore, while we do not want to micromanage a company's compensation programs, we will place limits on the potential dilution these plans may impose. Pioneer will vote for: o 401(k) benefit plans. o Employee stock ownership plans (ESOPs), as long as shares allocated to ESOPs are less than 5% of outstanding shares. Larger blocks of stock in ESOPs can serve as a takeover defense. We will support proposals to submit ESOPs to shareholder vote. o Various issues related to the Omnibus Budget and Reconciliation Act of 1993 (OBRA), including: o Amendments to performance plans to conform with OBRA; o Caps on annual grants or amendments of administrative features; o Adding performance goals; and o Cash or cash-and-stock bonus plans. o Establish a process to link pay, including stock-option grants, to performance, leaving specifics of implementation to the company. o Require that option repricings be submitted to shareholders. o Require the expensing of stock-option awards. o Require reporting of executive retirement benefits (deferred compensation, split-dollar life insurance, SERPs, and pension benefits). o Employee stock purchase plans where the purchase price is equal to at least 85% of the market price, where the offering period is no greater than 27 months and where potential dilution (as defined below) is no greater than 10%. 12 We will vote on a case-by-case basis on the following issues: o Executive and director stock-related compensation plans. We will consider the following factors when reviewing these plans: o The program must be of a reasonable size. We will approve plans where the combined employee and director plans together would generate less than 15% dilution. We will reject plans with 15% or more potential dilution. Dilution = (A + B + C) / (A + B + C + D), where A = Shares reserved for plan/amendment, B = Shares available under continuing plans, C = Shares granted but unexercised and D = Shares outstanding. o The plan must not: o Explicitly permit unlimited option repricing authority or that have repriced in the past without shareholder approval. o Be a self-replenishing "evergreen" plan, plans that grant discount options and tax offset payments. o We are generally in favor of proposals that increase participation beyond executives. o We generally support proposals asking companies to adopt rigorous vesting provisions for stock option plans such as those that vest incrementally over, at least, a three- or four-year period with a pro rata portion of the shares becoming exercisable on an annual basis following grant date. o We generally support proposals asking companies to disclose their window period policies for stock transactions. Window period policies ensure that employees do not exercise options based on insider information contemporaneous with quarterly earnings releases and other material corporate announcements. o We generally support proposals asking companies to adopt stock holding periods for their executives. o All other employee stock purchase plans. o All other compensation-related proposals, including deferred compensation plans, employment agreements, loan guarantee programs and retirement plans. o All other proposals regarding stock compensation plans, including extending the life of a plan, changing vesting restrictions, repricing options, lengthening exercise periods or accelerating distribution of awards and pyramiding and cashless exercise programs. 13 We will vote against: o Pensions for non-employee directors. We believe these retirement plans reduce director objectivity. o Elimination of stock option plans. We will vote on a case-by case basis on these issues: o Limits on executive and director pay. o Stock in lieu of cash compensation for directors. Corporate Governance Pioneer will vote for: o Confidential Voting. o Equal access provisions, which allow shareholders to contribute their opinion to proxy materials. o Proposals requiring directors to disclose their ownership of shares in the company. We will vote on a case-by-case basis on the following issues: o Change in the state of incorporation. We will support reincorporations supported by valid business reasons. We will oppose those that appear to be solely for the purpose of strengthening takeover defenses. o Bundled proposals. We will evaluate the overall impact of the proposal. o Adopting or amending the charter, bylaws or articles of association. o Shareholder appraisal rights, which allow shareholders to demand judicial review of an acquisition price. We will vote against: o Shareholder advisory committees. While management should solicit shareholder input, we prefer to leave the method of doing so to management's discretion. o Limitations on stock ownership or voting rights. o Reduction in share ownership disclosure guidelines. 14 Mergers and Restructurings Pioneer will vote on the following and similar issues on a case-by-case basis: o Mergers and acquisitions. o Corporate restructurings, including spin-offs, liquidations, asset sales, joint ventures, conversions to holding company and conversions to self-managed REIT structure. o Debt restructurings. o Conversion of securities. o Issuance of shares to facilitate a merger. o Private placements, warrants, convertible debentures. o Proposals requiring management to inform shareholders of merger opportunities. We will normally vote against shareholder proposals requiring that the company be put up for sale. Mutual Funds Many of our portfolios may invest in shares of closed-end mutual funds or exchange-traded funds. The non-corporate structure of these investments raises several unique proxy voting issues. Pioneer will vote for: o Establishment of new classes or series of shares. o Establishment of a master-feeder structure. Pioneer will vote on a case-by-case on: o Changes in investment policy. We will normally support changes that do not affect the investment objective or overall risk level of the fund. We will examine more fundamental changes on a case-by-case basis. o Approval of new or amended advisory contracts. o Changes from closed-end to open-end format. o Authorization for, or increase in, preferred shares. o Disposition of assets, termination, liquidation, or mergers. o Classified boards of closed-end mutual funds, but will typically support such proposals. 15 Social Issues Pioneer will abstain on stockholder proposals calling for greater disclosure of corporate activities with regard to social issues. "Social Issues" may generally be described as shareholder proposals for a company to: o Conduct studies regarding certain issues of public concern and interest; o Study the feasibility of the company taking certain actions with regard to such issues; or o Take specific action, including ceasing certain behavior and adopting company standards and principles, in relation to issues of public concern and interest. We believe these issues are important and should receive management attention. Pioneer will vote against proposals calling for substantial changes in the company's business or activities. We will also normally vote against proposals with regard to contributions, believing that management should control the routine disbursement of funds. 16 Item 8. Portfolio Managers of Closed-End Management Investment Companies. (a) If the registrant is a closed-end management investment company that is filing an annual report on this Form N-CSR,provide the following information: (1) State the name, title, and length of service of the person or persons employed by or associated with the registrant or an investment adviser of the registrant who are primarily responsible for the day-to-day management of the registrants portfolio (Portfolio Manager). Also state each Portfolio Managers business experience during the past 5 years. Additional Information About the Portfolio Managers Other Accounts Managed by the Portfolio Managers. The table below indicates, for each portfolio manager of the fund, information about the accounts other than the fund over which the portfolio manager has day-to-day investment responsibility. All information on the number of accounts and total assets in the table is as of April 30, 2010. For purposes of the table, "Other Pooled Investment Vehicles" may include investment partnerships, undertakings for collective investments in transferable securities ("UCITS") and other non-U.S. investment funds and group trusts, and "Other Accounts" may include separate accounts for institutions or individuals, insurance company general or separate accounts, pension funds and other similar institutional accounts but generally do not include the portfolio manager's personal investment accounts or those which the manager may be deemed to own beneficially under the code of ethics.

When a portfolio manager is responsible for the management of more than one account, the potential arises for the portfolio manager to favor one account over another. The principal types of potential conflicts of interest that may arise are discussed below. For the reasons outlined below, Pioneer does not believe that any material conflicts are likely to arise out of a portfolio manager's responsibility for the management of the fund as well as one or more other accounts. Although Pioneer has adopted procedures that it believes are reasonably designed to detect and prevent violations of the federal securities laws and to mitigate the potential for conflicts of interest to affect its portfolio management decisions, there can be no assurance that all conflicts will be identified or that all procedures will be effective in mitigating the potential for such risks. Generally, the risks of such conflicts of interest are increased to the extent that a portfolio manager has a financial incentive to favor one account over another. Pioneer has structured its compensation arrangements in a manner that is intended to limit such potential for conflicts of interest. The funds investment subadviser also has adopted certain compliance procedures which are designed to address these types of conflicts. However, there is no guarantee that such procedures will detect each situation in which a conflict might arise. See "Compensation of Portfolio Managers" below. o A portfolio manager could favor one account over another in allocating new investment opportunities that have limited supply, such as initial public offerings and private placements. If, for example, an initial public offering that was expected to appreciate in value significantly shortly after the offering was allocated to a single account, that account may be expected to have better investment performance than other accounts that did not receive an allocation of the initial public offering. Generally, investments for which there is limited availability are allocated based upon a range of factors including available cash and consistency with the accounts' investment objectives and policies. This allocation methodology necessarily involves some subjective elements but is intended over time to treat each client in an equitable and fair manner. Generally, the investment opportunity is allocated among participating accounts on a pro rata basis. Although Pioneer believes that its practices are reasonably designed to treat each client in an equitable and fair manner, there may be instances where a fund may not participate, or may participate to a lesser degree than other clients, in the allocation of an investment opportunity. o A portfolio manager could favor one account over another in the order in which trades for the accounts are placed. If a portfolio manager determines to purchase a security for more than one account in an aggregate amount that may influence the market price of the security, accounts that purchased or sold the security first may receive a more favorable price than accounts that made subsequent transactions. The less liquid the market for the security or the greater the percentage that the proposed aggregate purchases or sales represent of average daily trading volume, the greater the potential for accounts that make subsequent purchases or sales to receive a less favorable price. When a portfolio manager intends to trade the same security on the same day for more than one account, the trades typically are "bunched," which means that the trades for the individual accounts are aggregated and each account receives the same price. There are some types of accounts as to which bunching may not be possible for contractual reasons (such as directed brokerage arrangements). Circumstances may also arise where the trader believes that bunching the orders may not result in the best possible price. Where those accounts or circumstances are involved, Pioneer will place the order in a manner intended to result in as favorable a price as possible for such client. o A portfolio manager could favor an account if the portfolio manager's compensation is tied to the performance of that account to a greater degree than other accounts managed by the portfolio manager. If, for example, the portfolio manager receives a bonus based upon the performance of certain accounts relative to a benchmark while other accounts are disregarded for this purpose, the portfolio manager will have a financial incentive to seek to have the accounts that determine the portfolio manager's bonus achieve the best possible performance to the possible detriment of other accounts. Similarly, if Pioneer receives a performance-based advisory fee, the portfolio manager may favor that account, whether or not the performance of that account directly determines the portfolio manager's compensation. o A portfolio manager could favor an account if the portfolio manager has a beneficial interest in the account, in order to benefit a large client or to compensate a client that had poor returns. For example, if the portfolio manager held an interest in an investment partnership that was one of the accounts managed by the portfolio manager, the portfolio manager would have an economic incentive to favor the account in which the portfolio manager held an interest. o If the different accounts have materially and potentially conflicting investment objectives or strategies, a conflict of interest could arise. For example, if a portfolio manager purchases a security for one account and sells the same security for another account, such trading pattern may disadvantage either the account that is long or short. In making portfolio manager assignments, Pioneer seeks to avoid such potentially conflicting situations. However, where a portfolio manager is responsible for accounts with differing investment objectives and policies, it is possible that the portfolio manager will conclude that it is in the best interest of one account to sell a portfolio security while another account continues to hold or increase the holding in such security. Compensation of Portfolio Managers. Pioneer has adopted a system of compensation for portfolio managers that seeks to align the financial interests of the portfolio managers with those of shareholders of the accounts (including Pioneer funds) the portfolio managers manage, as well as with the financial performance of Pioneer. The compensation program for all Pioneer portfolio managers includes a base salary (determined by the rank and tenure of the employee) and an annual bonus program, as well as customary benefits that are offered generally to all full-time employees. Base compensation is fixed and normally reevaluated on an annual basis. Pioneer seeks to set base compensation at market rates, taking into account the experience and responsibilities of the portfolio manager. The bonus plan is intended to provide a competitive level of annual bonus compensation that is tied to the portfolio manager achieving superior investment performance and align the interests of the investment professional with those of shareholders, as well as with the financial performance of Pioneer. Any bonus under the plan is completely discretionary, with a maximum annual bonus that may be in excess of base salary. The annual bonus is based upon a combination of the following factors: o Quantitative Investment Performance. The quantitative investment performance calculation is based on pre-tax investment performance of all of the accounts managed by the portfolio manager (which includes the fund and any other accounts managed by the portfolio manager) over a one-year period (20% weighting) and four-year period (80% weighting), measured for periods ending on December 31. The accounts, which include the fund, are ranked against a group of mutual funds with similar investment objectives and investment focus (60%) and a broad-based securities market index measuring the performance of the same type of securities in which the accounts invest (40%), which, in the case of the fund, is the Merrill Lynch Global High Yield and Emerging Markets Index and the CSFB Leveraged Loan Index. As a result of these two benchmarks, the performance of the portfolio manager for compensation purposes is measured against the criteria that are relevant to the portfolio manager's competitive universe. o Qualitative Performance. The qualitative performance component with respect to all of the accounts managed by the portfolio manager includes objectives, such as effectiveness in the areas of teamwork, leadership, communications and marketing, that are mutually established and evaluated by each portfolio manager and management. o Pioneer Results and Business Line Results. Pioneer's financial performance, as well as the investment performance of its investment management group, affect a portfolio manager's actual bonus by a leverage factor of plus or minus (+/-) a predetermined percentage. The quantitative and qualitative performance components comprise 80% and 20%, respectively, of the overall bonus calculation (on a pre-adjustment basis). A portion of the annual bonus is deferred for a specified period and may be invested in one or more Pioneer funds. Certain portfolio managers may participate in other programs designed to reward and retain key contributors. Senior executives or other key employees may be granted performance units based on the stock price performance of UniCredit and the financial performance of Pioneer Global Asset Management S.p.A., which are affiliates of Pioneer. Portfolio managers also may participate in a deferred compensation program, whereby deferred amounts are invested in one or more Pioneer funds. Share Ownership by Portfolio Managers. The following table indicates as of April 30, 2010 the value, within the indicated range, of shares beneficially owned by the portfolio managers of the fund. --------------------------------------- ---------------------------------------- Name of Portfolio Manager Beneficial Ownership of the Fund* --------------------------------------- ---------------------------------------- --------------------------------------- ---------------------------------------- Charles Melchreit A --------------------------------------- ---------------------------------------- --------------------------------------- ---------------------------------------- Andrew Feltus D --------------------------------------- ---------------------------------------- --------------------------------------- ---------------------------------------- Jonathan Sharkey B --------------------------------------- ---------------------------------------- *Key to Dollar Ranges A.

Instruction to paragraph (a). Disclose all purchases covered by this Item, including purchases that do not satisfy the conditions of the safe harbor of Rule 10b-18 under the Exchange Act (17 CFR 240.10b-18), made in the period covered by the report.

ITEM 11. CONTROLS AND PROCEDURES. (a) Disclose the conclusions of the registrant's principal executive officer or officers and principal financial officer or officers, or persons performing similar functions, about the effectiveness of the registrant's disclosure controls and procedures (as defined in Rule 30a-2(c) under the Act (17 CFR 270.30a-2(c))) based on their evaluation of these controls and procedures as of a date within 90 days of the filing date of the report that includes the disclosure required by this paragraph. The registrant's principal executive officer and principal financial officer have concluded that the registrant's disclosure controls and procedures are effective based on their evaluation of these controls and procedures as of a date within 90 days of the filing date of this report. (b) Disclose whether or not there were significant changes in the registrant's internal controls or in other factors that could significantly affect these controls subsequent to the date of their evaluation, including any corrective actions with regard to significant deficiencies and material weaknesses. There were no significant changes in the registrant's internal control over financial reporting that occurred during the second fiscal quarter of the period covered by this report that have materially affected, or are reasonably likely to materially affect, the registrant's internal control over financial reporting. The registrant's principal executive officer and principal financial officer, however, voluntarily are reporting the following information: In August of 2006 the registrant's investment adviser enhanced its internal procedures for reporting performance information required to be included in prospectuses. Those enhancements involved additional internal controls over the appropriateness of performance data generated for this purpose. Such enhancements were made following an internal review which identified prospectuses relating to certain classes of shares of a limited number of registrants where, inadvertently, performance information not reflecting the deduction of applicable sales charges was included. Those prospectuses were revised, and the revised prospectuses were distributed to shareholders. ITEM 12. EXHIBITS. File the exhibits listed below as part of this Form. Letter or number the exhibits in the sequence indicated.
