Pioneer U.S. Government Money Market Fund | Semiannual Report | 6/30/17 1 President's Letter U.S. markets have continued to generate positive returns during the first several months of 2017, with so-called "risk" assets, such as equities and credit-sensitive bonds, posting solid gains. U.S. equities, as measured by the Standard & Poor's 500 Index, returned slightly more than 6% in the first calendar quarter of the year and more than 3% for the second quarter. Meanwhile, high-yield securities have dominated bond market performance thus far in 2017. The post-election market momentum we witnessed in the U.S. during the final weeks of the fourth quarter of 2016 slowed only when oil prices slumped in March, due to both higher-than-expected inventories and concerns over whether OPEC (Organization of Petroleum Exporting Countries) would continue its supply cuts. Not even the Federal Reserve System's (the Fed's) two rate hikes since March, nor Britain's trigger of Article 50 to begin the "Brexit" process caused any dramatic sell-off of risk assets. In fact, we are encouraged by the more hawkish stance of the Fed with regard to interest rates, in light of our view that current U.S. bond yields do not fairly reflect the prospective levels of economic activity and inflation. We expect the Fed to continue to tighten monetary policy, with at least one more rate hike likely to occur before the end of 2017. While U.S. gross domestic product (GDP) did slow in the first quarter, ending up at 1.4% after revisions, the expectation is for GDP growth to pick-up in the second quarter, with a solid consumer leading the way. It is our view that the U.S. economy may lead all developed nations in 2017, with GDP growth in excess of 2% for the full year, even if proposed tax and regulatory reforms are not passed into law in the near future. We also believe solid domestic employment figures should continue to support consumption and the housing market, and that stronger corporate profits and increased government spending may contribute to economic growth in 2018 and beyond. In addition, as we monitor global Purchasing Manager Indices (PMIs), we note that their numbers are increasing, which suggests that growth in global economies is also improving. (PMIs are used to measure the economic health of the manufacturing sector.) There are, as always, some risks to our outlook. First, the market already has priced in a good deal of the Trump economic reform platform, and that could lead to near-term disappointment if Congressional follow-through does not happen this year. The future of the Affordable Care Act (ACA) is another potential concern, as Congressional leaders have, thus far, failed to generate 2 Pioneer U.S. Government Money Market Fund | Semiannual Report | 6/30/17 enough support to get new health care legislation approved by both houses. However, if a bill is eventually passed that either eliminates or significantly alters the ACA, the new law will undoubtedly have an effect on the health care sector, one of the largest segments of the U.S. economy. Geopolitical risks, of course, remain a potential headwind, given ongoing strife in the Middle East and renewed tensions on the Korean Peninsula. While our current outlook is generally optimistic, conditions can and often do change, and while passive investment strategies may have a place in one's overall portfolio, it is our view that all investment decisions are active choices. Throughout our history, we have believed in the importance of active management. The active decisions to invest in equities or fixed-income securities are made by a team of experienced investment professionals focusing on identifying value across global markets using proprietary research, careful risk management, and a long-term perspective. We believe our shareowners can benefit from the experience and tenure of our investment teams as well as the insights generated from our extensive research process. As always, and particularly during times of market uncertainty, we encourage you to work with your financial advisor to develop an overall investment plan that addresses both your short- and long-term goals, and to implement such a plan in a disciplined manner. We greatly appreciate the trust you have placed in us and look forward to continuing to serve you in the future. Sincerely, /s/ Lisa M. Jones Lisa M. Jones Head of the Americas, President and CEO of US Amundi Pioneer Asset Management USA, Inc.

Pioneer U.S. Government Money Market Fund | Semiannual Report | 6/30/17 3 Portfolio Management Discussion | 6/30/17 Important Note: On July 3, 2017, Amundi acquired Pioneer Investments, a group of asset management companies located throughout the world. Amundi, one of the world's largest asset managers, is headquartered in Paris, France. As a result of the transaction, Pioneer Investment Management, Inc., the Fund's investment adviser, became an indirect wholly owned subsidiary of Amundi and Amundi's wholly owned subsidiary, Amundi USA, Inc. Prior to July 3, 2017, Pioneer Investments was owned by Pioneer Global Asset Management S.p.A., a wholly owned subsidiary of UniCredit S.p.A. In connection with the transaction, the names of the Fund's investment adviser and principal underwriter changed. Effective July 3, 2017, the name of Pioneer Investment Management, Inc. changed to Amundi Pioneer Asset Management, Inc. and the name of Pioneer Funds Distributor, Inc. changed to Amundi Pioneer Distributor, Inc. This transaction does not impact your existing relationship with Pioneer Investments, your advisor, or the methods you use to communicate with us, as the investor contact telephone numbers and services you expect will remain the same. We are excited, however, to be launching a new website representing the combined company. Come visit us at: www.amundipioneer.com. Money market interest rates crept higher during the six-month period ended June 30, 2017, as the U.S. Federal Reserve (the Fed) gradually hiked the key Federal funds rate. In the following discussion, Seth Roman reviews the factors that affected the performance of Pioneer U.S. Government Money Market Fund during the six-month period. Mr. Roman, a vice president and a portfolio manager at Amundi Pioneer Asset Management, Inc. ("Amundi Pioneer"), is responsible for the daily management of the Fund. Q How did the Fund perform during the six-month period ended June 30, 2017? A Pioneer U.S. Government Money Market Fund's Class A shares returned 0.06% at net asset value during the six-month period ended June 30, 2017. During the same period, the average return of the 170 mutual funds in Lipper's U.S. Government Money Market Funds Category was 0.09%. Q How would you describe the environment for money market investing during the six-month period ended June 30, 2017? A Interest rates in the short-term money market moved higher over the six months. Following an increase of 0.25% at the end of 2016, the Fed hiked the influential Fed funds rate twice more during the six-month period -- once in March and again in June. At the end of the period, the Fed's target rate for Fed funds was 1.00% to 1.25%. 4 Pioneer U.S. Government Money Market Fund | Semiannual Report | 6/30/17 Over the period, U.S. gross domestic product (GDP) maintained its modest annual growth rate of approximately 2%, despite a slight downturn in GDP in the first quarter, as new-job creation expanded at a robust pace and the housing market continued to gain momentum. Wage inflation, however, did not increase by as much as expected given an improving economy that had been rebounding for several years. As a consequence, the Fed hinted that, while it still planned to raise rates further in 2017 and 2018, some hikes might be delayed a bit if wage growth remains sluggish. Q How did you manage the Fund's portfolio in that environment during the six-month period ended June 30, 2017? A Throughout the period, we held to the Fund's primary objective, which is to protect shareholders' capital by maintaining a stable net asset value of $1.00 per share. We maintained a conservative positioning in the portfolio with regard to interest-rate sensitivity during the six-month period, even as we adjusted the Fund's average effective duration from 21 days to about 30 days. (Duration is a measure of the sensitivity of the price, or the value of principal, of a fixed-income investment to a change in interest rates, expressed as a number of years.) The longer duration, a move which we did not consider significant, was designed to increase the Fund's ability to capture additional interest income as short-term interest rates moved higher and as longer-dated securities began offering slightly more yield. At the same time, we also remained focused on the Fund's secondary objective, which is to maintain sufficient liquidity so that investors have access to their money. To maintain liquidity, we emphasized two types of holdings in the portfolio: tri-party repurchase agreements, which are overnight loans collateralized by either U.S. Treasuries or U.S. agency securities, and shorter-maturity U.S. Treasury bills with maturity dates of one month or less. While we continued to concentrate on the Fund's objectives of safety and liquidity, we did attempt to find additional income, where and when it was available. Among the investment vehicles we used to seek out additional income were U.S. Treasury floaters, which have daily resets of their interest rates and have the potential to offer slightly increasing yields over time as the Fed raises interest rates. Overall, the greatest concentration within the Fund's total investment portfolio during the period, including Treasury floaters, was in securities directly backed by the U.S. government, such as U.S. Treasury bills and notes. Q Did the Fund's yield change during the six-month period ended June 30, 2017? A The Fund's yield did move up somewhat as the Fed raised interest rates. Pioneer U.S. Government Money Market Fund | Semiannual Report | 6/30/17 5 Q What is your investment outlook? A Midway through the year, we are somewhat skeptical that the Federal government soon will add any significant fiscal stimulus to the economy, either through tax reform or infrastructure investment. Given that view, we think the economy is likely to continue to expand at a slow rate, with GDP staying close to an annualized growth rate of about 2%. Inflation remains well under control, with wage inflation staying below expectations. As we discussed, while the Fed continues to plan further rate hikes, it also has signaled that it is watching for more evidence of rising wage inflation, and it is therefore possible that some anticipated rate increases may be delayed, although the Fed will likely be careful not to send out any signals suggesting that the economy is weakening. Six of the Fund's 10 largest positions as of June 30, 2017, were U.S. Treasury floaters. Going forward, we intend to maintain a healthy exposure in the portfolio to floating-rate securities in an effort to capture additional yield opportunities, but we will maintain our primary focus on capital preservation. Please refer to the Schedule of Investments on pages 12-15 for a full listing of Fund securities. You could lose money by investing in the Fund. Although the Fund seeks to preserve the value of your investment at $1.00 per share, it cannot guarantee it will do so. The Fund may impose a fee upon the sale of your shares or may temporarily suspend your ability to sell shares if the Fund's liquidity falls below required minimums because of market conditions or other factors. An investment in the Fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The Fund's sponsor has no legal obligation to provide financial support to the Fund, and you should not expect that the sponsor will provide financial support to the Fund at any time. All investments are subject to risk, including the possible loss of principal. In the past several years, financial markets have experienced increased volatility, depressed valuations, decreased liquidity and heightened uncertainty. These conditions may continue, recur, worsen or spread. The securities issued by U.S. Government-sponsored entities (e.g., FNMA, Freddie Mac) are neither guaranteed nor issued by the U.S. Government. At times, the Fund's investments may represent industries or industry sectors that are interrelated or have common risks, making it more susceptible to any economic, political, or regulatory developments or other risks affecting those industries and sectors. These risks may increase share price volatility. Before investing, consider the product's investment objectives, risks, charges and expenses.

The performance data quoted represents past performance, which is no guarantee of future results. Investment return and principal value will fluctuate, and shares, when redeemed, may be worth more or less than their original cost. Amundi Pioneer has agreed to limit the Fund's expenses for any class of shares or waive a portion of its management fee in an effort to maintain a net asset value of $1.00 per share. From time to time, Amundi Pioneer and its affiliates may limit the expenses of one or more classes for the purpose of avoiding a negative yield or increasing its yield during the period of the limitation. These expense limitation policies are voluntary and temporary and may be revised or terminated by Amundi Pioneer at any time without notice. Performance does not reflect the deduction of taxes that a shareowner would pay on Fund distributions or the redemption of Fund shares. Pioneer U.S. Government Money Market Fund | Semiannual Report | 6/30/17 9 Comparing Ongoing Fund Expenses As a shareowner in the Fund, you incur two types of costs: (1) ongoing costs, including management fees, distribution and/or service (12b-1) fees, and other Fund expenses; and (2) transaction costs, including sales charges (loads) on purchase payments. This example is intended to help you understand your ongoing expenses (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 at the beginning of the Fund's latest six-month period and held throughout the six months. Using the Tables -------------------------------------------------------------------------------- Actual Expenses The first table below provides information about actual account values and actual expenses. You may use the information in this table, together with the amount you invested, to estimate the expenses that you paid over the period as follows: (1) Divide your account value by $1,000 Example: an $8,600 account value (divided by) $1,000 = 8.6 (2) Multiply the result in (1) above by the corresponding share class's number in the third row under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. Expenses Paid on a $1,000 Investment in Pioneer U.S. Government Money Market Based on actual returns from January 1, 2017, through June 30, 2017.
-------------------------------------------------------------------------------- Share Class A Y -------------------------------------------------------------------------------- Beginning Account Value $1,000.00 $1,000.00 Value on 1/1/17 -------------------------------------------------------------------------------- Ending Account $1,000.60 $1,001.00 Value on 6/30/17 -------------------------------------------------------------------------------- Expenses Paid $ 2.98 $ 2.58 During Period* --------------------------------------------------------------------------------
* Expenses are equal to the Fund's annualized net expense ratio of 0.60% and 0.52% for Class A and Class Y shares, respectively, multiplied by the average account value over the period, multiplied by 181/365 (to reflect the one-half year period). 10 Pioneer U.S. Government Money Market Fund | Semiannual Report | 6/30/17 Hypothetical Example for Comparison Purposes The table below provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the tables are meant to highlight your ongoing costs only and do not reflect any transaction costs, such as sales charges (loads) that are charged at the time of the transaction. Therefore, the table below is useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds. In addition, if these transaction costs were included, your costs would have been higher.

(c) At June 30, 2017, cost for federal income tax purposes was $289,652,087. The Fund is permitted to engage in purchase and sale transactions ("cross trades") with certain funds and accounts for which Amundi Pioneer Asset Management, Inc. (Amundi Pioneer), formerly Pioneer Investment Management, Inc. (PIM), serves as the Fund's investment adviser, as set forth in Rule 17a-7 under the Investment Company Act of 1940, pursuant to procedures adopted by the Board of Trustees. Under these procedures, cross trades are effected at current market prices. During the six months ended June 30, 2017, the Fund did not engage in cross trade activity. Various inputs are used in determining the value of the Fund's investments. These inputs are summarized in the three broad levels below. Level 1 - quoted prices in active markets for identical securities. Level 2 - other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risks, etc.). See Notes to Financial Statements -- Note 1A. Level 3 - significant unobservable inputs (including the Fund's own assumptions in determining fair value of investments). See Notes to Financial Statements -- Note 1A. The following is a summary of the inputs used as of June 30, 2017, in valuing the Fund's investments:

Pioneer U.S. Government Money Market Fund | Semiannual Report | 6/30/17 21 Notes to Financial Statements | 6/30/17 (unaudited) 1. Organization and Significant Accounting Policies Pioneer U.S. Government Money Market Fund (the Fund) is a series of Pioneer Money Market Trust, a Delaware statutory trust. The Fund is registered under the Investment Company Act of 1940 as a diversified, open-end management investment company. The investment objective of the Fund is to provide high current income, preservation of capital, and liquidity through investments in high-quality short-term securities. The Fund offered two classes of shares designated as Class A and Class Y shares. Each class of shares represents an interest in the same portfolio of investments of the Fund and has identical rights (based on relative net asset values) to assets and liquidation proceeds. Share classes can bear different rates of class-specific fees and expenses such as transfer agent and distribution fees. Differences in class-specific fees and expenses will result in differences in net investment income and, therefore, the payment of different dividends from net investment income earned by each class. The Amended and Restated Declaration of Trust of the Fund gives the Board of Trustees the flexibility to specify either per-share voting or dollar-weighted voting when submitting matters for shareowner approval. Under per-share voting, each share of a class of the Fund is entitled to one vote. Under dollar-weighted voting, a shareowner's voting power is determined not by the number of shares owned, but by the dollar value of the shares on the record date. Each share class has exclusive voting rights with respect to matters affecting only that class, including with respect to the distribution plan for that class. There is no distribution plan for Class Y shares. On July 3, 2017, Amundi acquired Pioneer Investments, a group of asset management companies located throughout the world. Amundi, one of the world's largest asset managers, is headquartered in Paris, France. As a result of the transaction, Pioneer Investment Management, Inc., the Fund's investment adviser, became an indirect wholly owned subsidiary of Amundi and Amundi's wholly owned subsidiary, Amundi USA, Inc. Prior to July 3, 2017, Pioneer Investments was owned by Pioneer Global Asset Management S.p.A., a wholly owned subsidiary of UniCredit S.p.A. In connection with the transaction, the names of the Fund's investment adviser and principal underwriter changed. Effective July 3, 2017, the name of Pioneer Investment Management, Inc. changed to Amundi Pioneer Asset Management, Inc. and the name of Pioneer Funds Distributor, Inc. changed to Amundi Pioneer Distributor, Inc. 22 Pioneer U.S. Government Money Market Fund | Semiannual Report | 6/30/17 The Fund's financial statements have been prepared in conformity with U.S. generally accepted accounting principles (U.S. GAAP) that require the management of the Fund to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of income, expenses and gain or loss on investments during the reporting period. Actual results could differ from those estimates. The Fund is an investment company and follows investment company accounting and reporting guidance under U.S. GAAP. The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements: A. Security Valuation The net asset value of the Fund is computed once daily, on each day the New York Stock Exchange (NYSE) is open, as of the close of regular trading on the NYSE. Fixed income securities are valued by using 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, or may use a pricing matrix or other fair value methods or techniques to provide an estimated value of the security or instrument. A pricing matrix is a means of valuing a debt security on the basis of current market prices for other debt securities, historical trading patterns in the market for fixed income securities and/or other factors. Non-U.S. debt securities that are listed on an exchange will be valued at the bid price obtained from an independent third party pricing service. When independent third party pricing services are unable to supply prices, or when prices or market quotations are considered to be unreliable, the value of that security may be determined using quotations from one or more broker-dealers. Securities for which independent pricing services or broker-dealers are unable to supply prices or for which market prices and/or quotations are not readily available or are considered to be unreliable are valued by a fair valuation team comprised of certain personnel of Amundi Pioneer Asset Management, Inc. (Amundi Pioneer), formerly Pioneer Investment Management, Inc. (PIM), the Fund's investment adviser, pursuant to procedures adopted by the Fund's Board of Trustees. Amundi Pioneer's, formerly PIM's, fair valuation team uses fair value methods approved by the Valuation Committee of the Board of Trustees. Amundi Pioneer's, formerly PIM's, fair valuation team is responsible for monitoring developments that may impact fair valued securities and for discussing and assessing fair values on an ongoing basis, and at least quarterly, with the Valuation Committee of the Board of Trustees. Pioneer U.S. Government Money Market Fund | Semiannual Report | 6/30/17 23 Shares of open-end registered investment companies (including money market mutual funds) are valued at such funds' net asset value. Repurchase agreements are valued at par. Cash may include overnight time deposits at approved financial institutions. At June 30, 2017, there were no securities valued using fair value methods (other than securities valued using prices supplied by independent pricing services). B. Investment Income and Transactions Investments purchased at a discount or premium are valued by amortizing the difference between the original purchase price and maturity value of the issue over the period to maturity. Interest income, including interest on income bearing cash accounts, is recorded on the accrual basis. Security transactions are recorded as of trade date. Gains and losses on sales of investments are calculated on the identified cost method for both financial reporting and federal income tax purposes. C. Federal Income Taxes It is the Fund's policy to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its net taxable income and net realized capital gains, if any, to its shareowners. Therefore, no provision for federal income taxes is required. As of December 31, 2016, the Fund did not accrue any interest or penalties with respect to uncertain tax positions, which if applicable, would be recorded as an income tax expense in the Statement of Operations. Tax returns filed within the prior three years remain subject to examination by federal and state tax authorities. The amount and character of income and capital gain distributions to shareowners are determined in accordance with federal income tax rules, which may differ from U.S. GAAP. Distributions in excess of net investment income or net realized gains are temporary overdistributions for financial statement purposes resulting from differences in the recognition or classification of income or distributions for financial statement and tax purposes. Capital accounts within the financial statements are adjusted for permanent book/tax differences to reflect tax character, but are not adjusted for temporary differences. The tax character of current year distributions payable to shareowners will be determined at the end of the current taxable year. 24 Pioneer U.S. Government Money Market Fund | Semiannual Report | 6/30/17 The tax character of current year distributions payable will be determined at the end of the current taxable year. The tax character of distributions during the year ended December 30, 2016 was as follows:
--------------------------------------------------------------------------- 2016 --------------------------------------------------------------------------- Distributions paid from: Ordinary income $31,834 --------------------------------------------------------------------------- Total $31,834 ===========================================================================
The following shows the components of distributable earnings (losses) on a federal income tax basis at December 31, 2016:
--------------------------------------------------------------------------- 2016 --------------------------------------------------------------------------- Distributable earnings: Undistributed ordinary income $ 6,230 Other book/tax temporary differences (17,881) --------------------------------------------------------------------------- Total $(11,651) ===========================================================================
D. Fund Shares The Fund records sales and repurchases of its shares as of trade date. The Fund declares as daily dividends substantially all of its net investment income. All dividends are paid on a monthly basis. Short-term capital gain distributions, if any, may be declared with the daily dividends. E. Class Allocations Income, common expenses and realized and unrealized gains and losses are calculated at the Fund level and allocated daily to each class of shares based on its respective percentage of adjusted net assets at the beginning of the day. Distribution fees are calculated based on the average daily net asset value attributable to Class A shares of the Fund (see Note 4). Class Y shares do not pay distribution fees. All expenses and fees paid to the Fund's transfer agent for its services are allocated among the classes of shares based on the number of accounts in each class and the ratable allocation of related out-of-pocket expenses (see Note 3). Distributions to shareowners are recorded as of the ex-dividend date. Distributions paid by the Fund with respect to each class of shares are calculated in the same manner and at the same time, except that net investment income dividends to Class A and Class Y shares can reflect different transfer agent and distribution expense rates. Pioneer U.S. Government Money Market Fund | Semiannual Report | 6/30/17 25 F. Risks Although the Fund seeks to preserve the value of your investment at $1.00 per share, it cannot guarantee it will do so. It is possible to lose money by investing in the Fund. Fund shares are not federally insured by the Federal Deposit Insurance Corporation or any other government agency. The Fund's sponsor has no legal obligation to provide financial support to the Fund, and you should not expect that the sponsor will provide financial support at any time. At times, the Fund's investments may represent industries or industry sectors that are interrelated or have common risks, making the Fund more susceptible to any economic, political, or regulatory developments or other risks affecting those industries and industry sectors. The Fund's prospectus contains unaudited information regarding the Fund's principal risks. Please refer to that document when considering the Fund's principal risks. G. Repurchase Agreements Repurchase agreements are arrangements under which the Fund purchases securities from a broker-dealer or a bank, called the counterparty, upon the agreement of the counterparty to repurchase the securities from the Fund at a later date, and at a specific price, which is typically higher than the purchase price paid by the Fund. The securities purchased serve as the Fund's collateral for the obligation of the counterparty to repurchase the securities. The value of the collateral, including accrued interest, is required to be equal to or in excess of the repurchase price. The collateral for all repurchase agreements is held in safekeeping in the customer-only account of the Fund's custodian or a subcustodian of the Fund. Amundi Pioneer, formerly PIM, is responsible for determining that the value of the collateral remains at least equal to the repurchase price. In the event of a default by the counterparty, the Fund is entitled to sell the securities, but the Fund may not be able to sell them for the price at which they were purchased, thus causing a loss to the Fund. Additionally, if the counterparty becomes insolvent, there is some risk that the Fund will not have a right to the securities, or the immediate right to sell the securities. Open repurchase agreements as of June 30, 2017 are disclosed in the Fund's Schedule of Investments. 2. Management Agreement Amundi Pioneer, formerly PIM, manages the Fund's portfolio. Management fees are calculated daily at the annual rate of 0.35% of the Fund's average daily net assets up to $1 billion and 0.30% on assets over $1 billion. For the six months ended June 30, 2017, the net management fee (excluding waivers and/or reimbursement of expenses) was equivalent to 0.35% (annualized). 26 Pioneer U.S. Government Money Market Fund | Semiannual Report | 6/30/17 Amundi Pioneer, formerly PIM, has agreed to limit the Fund's expenses for any class of shares or waive a portion of its management fee in an effort to maintain a net asset value of $1.00 per share. From time to time, Amundi Pioneer, formerly PIM, and its affiliates may limit the expenses of one or more classes for the purpose of avoiding a negative yield or increasing its yield during the period of the limitation. These expense limitation policies are voluntary and temporary and may be revised or terminated by Amundi Pioneer, formerly PIM, at any time without notice. Fees waived and expenses reimbursed during the six months ended June 30, 2017 are reflected on the Statement of Operations. In addition, under the management and administration agreements, certain other services and costs, including accounting, regulatory reporting and insurance premiums, are paid by the Fund as administrative reimbursements. Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $33,505 in management fees, administrative costs and certain other reimbursements payable to Amundi Pioneer, formerly PIM, at June 30, 2017. 3. Transfer Agent Boston Financial Data Services serves as the transfer agent to the Fund at negotiated rates. Transfer agent fees and payables shown on the Statement of Operations and the Statement of Assets and Liabilities, respectively, include sub-transfer agent expenses incurred through the Fund's omnibus relationship contracts. In addition, the Fund reimbursed the transfer agent for out-of-pocket expenses incurred by the transfer agent related to shareowner communications activities such as proxy and statement mailings and outgoing phone calls. For the six months ended June 30, 2017, such out-of-pocket expenses by class of shares were as follows:
-------------------------------------------------------------------------------- Shareowner Communications: -------------------------------------------------------------------------------- Class A $57,224 Class Y -- -------------------------------------------------------------------------------- Total $57,224 ================================================================================
4. Distribution and Service Plans The Fund has adopted a Distribution Plan (the Plan) pursuant to Rule 12b-1 of the Investment Company Act of 1940 with respect to its Class A shares. Pursuant to the Plan, the Fund pays Amundi Pioneer Distributor, Inc., formerly Pioneer Funds Distributor, Inc., 0.15% of the average daily net assets attributable to Class A shares as compensation for personal services and/or account maintenance services or distribution services with regard to Class A Pioneer U.S. Government Money Market Fund | Semiannual Report | 6/30/17 27 shares. From January 1, 2017 until the six months ended June 30, 2017, the Plan paid 0.15% (annualized) and subsequently waived the amount. Fees waived and expenses reimbursed during the six months ended June 30, 2017 are reflected on the Statement of Operations. 5.

28 Pioneer U.S. Government Money Market Fund | Semiannual Report | 6/30/17 ADDITIONAL INFORMATION Class R will commence operations on August 1, 2017. Change in Independent Registered Public Accounting Firm Prior to July 3, 2017 Pioneer Investment Management, Inc. (the "Adviser"), the Fund's investment adviser, was an indirect, wholly owned subsidiary of UniCredit S.p.A. ("UniCredit"). On that date, UniCredit completed the sale of its Pioneer Investments business, which includes the Adviser, to Amundi (the "Transaction"). As a result of the Transaction, the Adviser became an indirect, wholly-owned subsidiary of Amundi. Amundi is controlled by Credit Agricole S.A. Amundi is headquartered in Paris, France, and, as of September 30, 2016, had more than $1.1 trillion in assets under management worldwide. Deloitte & Touche LLP ("D&T"), the Fund's previous independent registered public accounting firm, informed the Audit Committee and the Board that it would no longer be independent with respect to the Fund upon the completion of the Transaction as a result of certain services being provided to Amundi and Credit Agricole, and, accordingly, that it intended to resign as the Fund's independent registered public accounting firm upon the completion of the Transaction. D&T's resignation was effective on July 3, 2017, when the Transaction was completed. During the periods as to which D&T has served as the Fund's independent registered public accounting firm, including the Fund's two most recent fiscal years preceding the fiscal year ended December 31, 2017, D&T's reports on the Fund's financial statements have not contained an adverse opinion or disclaimer of opinion and have not been qualified or modified as to uncertainty, audit scope or accounting principles. Further, there have been no disagreements with D&T on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which, if not resolved to the satisfaction of D&T, would have caused D&T to make reference to the subject matter of the disagreement in connection with its report on the financial statements. In addition, there have been no reportable events of the kind described in Item 304(a)(1)(v) of Regulation S-K under the Securities Exchange Act of 1934. Effective immediately following the completion of the Transaction on July 3, 2017, the Board, acting upon the recommendation of the Audit Committee, engaged a new independent registered public accounting firm, Ernst & Young LLP ("EY"), for the Fund's fiscal year ended December 31, 2017. Prior to its engagement, EY had advised the Fund's Audit Committee that EY had identified the following matters, in each case relating to services rendered by other member firms of Ernst & Young Global Limited, all of which are located outside the United States, to UniCredit and certain of its subsidiaries Pioneer U.S. Government Money Market Fund | Semiannual Report | 6/30/17 29 during the period commencing July 1, 2016, that it determined to be inconsistent with the auditor independence rules set forth by the Securities and Exchange Commission ("SEC"): (a) project management support services to UniCredit in the Czech Republic, Germany, Italy, Serbia and Slovenia in relation to twenty-two projects, that were determined to be inconsistent with Rule 2-01(c)(4)(vi) of Regulation S-X (management functions); (b) two engagements for UniCredit in Italy where fees were contingent/success based and that were determined to be inconsistent with Rule 2-01(c)(5) of Regulation S-X (contingent fees); (c) four engagements where legal and expert services were provided to UniCredit in the Czech Republic and Germany, and twenty engagements where the legal advisory services were provided to UniCredit in Austria, Czech Republic, Italy and Poland, that were determined to be inconsistent with Rule 2-01(c)(4)(ix) and (x) of Regulation S-X (legal and expert services); and (d) two engagements for UniCredit in Italy involving assistance in the sale of certain assets, that were determined to be inconsistent with Rule 2-01(c)(4)(viii) of Regulation S-X (broker-dealer, investment advisor or investment banking services). None of the foregoing services involved the Fund, any of the other funds in the Pioneer Family of Funds or any other Pioneer entity sold by UniCredit in the Transaction. EY advised the Audit Committee that it had considered the matters described above and had concluded that such matters would not impair EY's ability to exercise objective and impartial judgment in connection with the audits of the financial statements of the Fund under the SEC and Public Company Accounting Oversight Board independence rules, and that a reasonable investor with knowledge of all relevant facts and circumstances would reach the same conclusion. Management and the Audit Committee considered these matters and discussed the matters with EY and, based upon EY's description of the matters and statements made by EY, Management and the Audit Committee believe that EY will be capable of exercising objective and impartial judgment in connection with the audits of the financial statements of the Fund, and Management further believes that a reasonable investor with knowledge of all relevant facts and circumstances would reach the same conclusion. 30 Pioneer U.S. Government Money Market Fund | Semiannual Report | 6/30/17 Approval of New and Interim Management Agreements Amundi Pioneer Asset Management, Inc. (Amundi Pioneer), formerly Pioneer Investment Management, Inc. (PIM), serves as the investment adviser to Pioneer U.S. Government Money Market Fund (the Fund) pursuant to an investment management agreement between Amundi Pioneer and the Fund. On July 3, 2017, Amundi acquired Pioneer Investments, a group of asset management companies located throughout the world (the "Transaction"). As a result of the Transaction, Amundi Pioneer became an indirect wholly-owned subsidiary of Amundi and Amundi's wholly-owned subsidiary, Amundi USA, Inc. Prior to July 3, 2017, Pioneer Investments was owned by Pioneer Global Asset Management S.p.A. ("PGAM"), a wholly-owned subsidiary of UniCredit S.p.A. ("UniCredit"). Under the Investment Company Act of 1940, the Fund's investment management agreement with PIM (the "Current Management Agreement") terminated automatically upon the consummation of the Transaction. In order for Amundi Pioneer to continue to manage the Fund after the consummation of the Transaction, the Trustees and shareholders of the Fund were required to approve a new investment management agreement for the Fund (the "New Management Agreement"). As discussed below, the Board of Trustees of the Fund approved the New Management Agreement at a meeting held on March 6-7, 2017. The New Management Agreement was approved by the shareholders of the Fund at a meeting held on June 13, 2017. The Board of Trustees of the Fund also approved an interim investment management agreement between Amundi Pioneer and the Fund (the "Interim Management Agreement") at the March 6-7, 2017 meeting. The Interim Management Agreement would have taken effect upon the closing of the Transaction in the event that the shareholders of the Fund did not approve the New Management Agreement. Board Evaluation of the New and Interim Management Agreements The Board evaluated the Transaction and the New Management Agreement and Interim Management Agreement for the Fund. In connection with their evaluation of the Transaction and the New Management Agreement for the Fund, the Trustees requested such information as they deemed reasonably necessary, including: (a) the structure of the Transaction and the strategy underlying the Transaction; (b) the anticipated benefits of the Transaction to the Fund and its shareholders; (c) the post-Transaction plans for Amundi Pioneer, including Amundi's plans for integration of Pioneer Investments and Amundi Pioneer with its existing asset management businesses and plans for the future development of Amundi Pioneer; (d) the effect of the Transaction on the ongoing services provided to the Fund, including the need to select a Pioneer U.S. Government Money Market Fund | Semiannual Report | 6/30/17 31 new independent registered public accounting firm for the Fund, and any plans to modify the operations of the Fund; (e) the stability and continuity of Amundi Pioneer's management and key employees, including compensation and benefits to Amundi Pioneer's key employees, and retention plans and incentive plan structure; (f) the post-Transaction indebtedness and financial resources of Amundi Pioneer; (g) Amundi's legal and operational structure, its principal shareholders and senior management, its investment management, risk management, administrative, legal and compliance functions; (h) certain regulatory matters relating to Amundi's affiliates; and (i) Amundi's commitment to the United States, including the role of Amundi Pioneer in the larger Amundi business. The Trustees also requested and obtained the following information in connection with their evaluation of the Transaction and the New Management Agreement for the Fund: (i) memoranda provided by Fund counsel that summarized the legal standards and other considerations that are relevant to the Trustees in their deliberations regarding the New Management Agreement; (ii) the qualifications of the investment management teams for the Fund, as well as the level of investment by the Fund's portfolio managers in the Fund; (iii) the Fund's management fees and total expense ratios, the financial statements of Amundi Pioneer and its pre- and post-Transaction parent companies, profitability analyses from Amundi Pioneer, and analyses from Amundi Pioneer as to possible economies of scale; (iv) the profitability of the institutional business of Amundi Pioneer and Amundi Pioneer's affiliate, Amundi Pioneer Institutional Asset Management, Inc. ("Amundi Pioneer Institutional") as compared to that of Amundi Pioneer's fund management business; and (v) the differences between the fees and expenses of the Fund and the fees and expenses of Amundi Pioneer's and Amundi Pioneer Institutional's institutional accounts, as well as the different services provided by Adviser to the Fund and by Amundi Pioneer and Amundi Pioneer Institutional to the institutional accounts. In addition, the Trustees considered the information provided at regularly scheduled meetings throughout the year regarding the Fund's performance and risk attributes, including through meetings with investment management personnel, and took into account other information related to the Fund provided to the Trustees at regularly scheduled meetings. The Trustees also considered information they had received in their review of the continuance of the Current Management Agreement for the Fund in September 2016. At meetings held on January 9, 2017 and January 10, 2017, the Trustees met with representatives of Amundi and PGAM, including separate meetings of the Trustees who are not "interested persons" of the Fund Complex ("Independent Trustees") and counsel with representatives of Amundi and PGAM, and subsequently with representatives of Amundi. In those meetings, 32 Pioneer U.S. Government Money Market Fund | Semiannual Report | 6/30/17 they received an extensive presentation from the representatives of Amundi, including the chief executive officer of Amundi, describing Amundi's background and history, its global asset management activities, the growth of its business, and its status as the largest asset management firm in Europe and one of the largest globally; its capital structure and financial resources, including information as to the financing of the Transaction; its principal investors, including its majority investor Credit Agricole S.A., and Credit Agricole's long-term commitment to the asset management business; the philosophy and strategy underlying the Transaction and the complementarity of Amundi's and Pioneer Investments' respective asset management businesses; Amundi's various operating and investment committees and how they would likely interact with Amundi Pioneer; the proposed integration process, including the progress to date and the establishment of various integration work streams; Amundi's plans for management of Amundi Pioneer; Amundi's philosophy as to compensation of key employees and its general intentions with respect to incentive plans for key employees of Amundi Pioneer; Amundi's preliminary plans to achieve cost and other synergies; and opportunities to further develop the business of Amundi Pioneer and Amundi Pioneer Institutional, including in the area of institutional asset management, and how that would benefit shareholders of the Pioneer Funds. In those meetings, the representatives of Amundi confirmed their intention that the Chief Executive Officer and Chief Investment Officer of Amundi Pioneer would remain in their current positions, and confirmed that they do not currently foresee major changes in the day-to-day investment management operations of Amundi Pioneer with respect to the Fund as a direct result of the Transaction. They discussed incentive arrangements for key personnel that would continue after the closing of the Transaction and their plans to establish a new long-term incentive plan following the closing. They also generally discussed ways in which Amundi Pioneer could potentially draw on the expanded global resources of Amundi post-Transaction. At those meetings, the Independent Trustees identified certain areas to which they requested further information, including as to trading and execution of securities transactions, research and portfolio management and potential changes in investment process, particularly where asset classes managed by Amundi Pioneer would overlap with asset classes managed by Amundi, the continued availability of resources currently at Pioneer Investments or elsewhere within Amundi to assist in management of certain Funds, and any anticipated significant changes in operations. The Independent Trustees considered the uncertainty as to whether the Fund's independent registered public accounting firm could continue to act in that capacity after the closing of the Transaction. The Independent Trustees also met with counsel to review the information they had received to date and to discuss next steps. Pioneer U.S. Government Money Market Fund | Semiannual Report | 6/30/17 33 Subsequently, the Trustees received further information from Amundi, including written responses to questions raised by the Independent Trustees, and received from Amundi Pioneer the information requested of it. The Independent Trustees reviewed the information provided with counsel at telephonic meetings held on February 16, 2017 and February 27, 2017. The Trustees held a special in-person Board meeting on March 6-7, 2017 for further consideration of the New Management Agreements, the Interim Management Agreements and the Transaction. The Trustees met again with senior executives of Amundi at the March 6-7, 2017 meeting. At the March 6-7, 2017 meeting, based on their evaluation of the information provided by Amundi Pioneer and Amundi, the Trustees including the Independent Trustees voting separately, approved the New Management Agreement and the Interim Management Agreement for the Fund. In considering the New Management Agreement for the Fund, 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 their determinations. The Trustees considered the same factors with respect to the Interim Management Agreement for the Fund. Nature, Extent and Quality of Services The Trustees considered the nature, extent and quality of the services that had been provided by Amundi Pioneer to the Fund and that are expected to be provided by Amundi Pioneer to the Fund following the consummation of the Transaction. The Trustees reviewed the terms of the New Management Agreement, and noted that such terms are substantially similar to the terms of the Current Management Agreement, except for different execution dates, effective dates and termination dates. The Trustees reviewed Amundi Pioneer's investment approach for the Fund and its research process. The Trustees considered the resources of Amundi Pioneer and the personnel of Amundi Pioneer who provide investment management services to the Fund. They also reviewed the amount of non-investment resources and personnel of Amundi Pioneer that are involved in Amundi Pioneer's services to the Fund, including Amundi Pioneer's compliance and legal resources and personnel. The Trustees noted the substantial attention and high priority given by Amundi Pioneer's senior management to the Pioneer Fund complex. The Trustees considered that Amundi Pioneer supervises and monitors the performance of the Fund's service providers and provides the Fund with personnel (including Fund officers) and other resources that are necessary for the Fund's business management and operations and that Amundi Pioneer would continue to provide those investment management and research services and resources to the Fund following the consummation of the Transaction. The Trustees also considered that, as administrator, Amundi 34 Pioneer U.S. Government Money Market Fund | Semiannual Report | 6/30/17 Pioneer would continue to be responsible for the administration of the Fund's business and other affairs. The Trustees considered the fees to be paid to Amundi Pioneer for the provision of administration services. The Trustees considered that Deloitte & Touche LLP informed the Board that it would no longer be independent with respect to the Fund upon the completion of the Transaction and, accordingly, that it would be necessary for the Board to engage a new independent registered public accounting firm for the Fund. The Trustees considered that the Transaction was not expected to have a material adverse impact on the nature, scope and overall quality of services provided to the Fund and its shareholders, including investment management, risk management, administrative, compliance, legal and other services, as a result of the Transaction. In that regard, the Trustees considered that Amundi is one of the largest asset managers globally, and that Amundi Pioneer may have access to additional research and portfolio management capabilities as a result of the Transaction and that Amundi Pioneer, as part of Amundi, is expected to have an enhanced global presence that may contribute to an increase in the overall scale and resources of Amundi Pioneer. Furthermore, in considering whether the Transaction would be expected to have a material adverse impact on the nature, scope and overall quality of services provided to the Fund and its shareholders, the Trustees considered the statements by representatives of Amundi that they expect the Chief Executive Officer and Chief Investment Officer of Amundi Pioneer to remain in their current positions and that they do not currently foresee major changes in the day-to-day investment management operations of Amundi Pioneer as a direct result of the Transaction, or the risk management, legal or compliance services provided by Amundi Pioneer, with respect to the Fund. They further considered the current incentive arrangements for key personnel of Amundi Pioneer that would continue after the closing of the Transaction. They also noted Amundi's stated intention to establish a new long-term incentive plan following the closing. The Trustees also took into account their experience in evaluating the proposed combination of Pioneer Investments and Santander Asset Management, which was announced in September, 2014 and abandoned in July, 2016. In light of, among other things, this experience, the Trustees determined that they were not able to identify any realistic alternatives to approving the New Management Agreement that would provide the level of services to the Fund and its shareholders that are expected to be provided by Amundi Pioneer after the closing of the Transaction. Pioneer U.S. Government Money Market Fund | Semiannual Report | 6/30/17 35 Based on these considerations, the Trustees concluded that the nature, extent and quality of services that Amundi Pioneer would continue to provide to the Fund under the New Management Agreement would be satisfactory and consistent with the terms of the New Management Agreement. Performance of the Fund In considering the Fund's performance, the Trustees regularly reviewed and discussed throughout the year data prepared by Amundi Pioneer and information comparing the Fund's performance with the performance of its peer group of funds, as classified by each of Morningstar, Inc. (Morningstar) and Lipper, and the performance of the Fund's benchmark index. They also discussed the Fund's performance with Amundi Pioneer on a regular basis. The Trustees' regular reviews and discussions were factored into the Trustees' deliberations concerning the approval of the New Management Agreement. Management Fee and Expenses The Trustees noted that the stated management fees to be paid by the Fund are identical under the Current Management Agreement and the New Management Agreement. The Trustees considered information showing the fees and expenses of the Fund in comparison to the management fees and expense ratios of its peer group of funds as classified by Morningstar and also to the expense ratios of a peer group of funds selected on the basis of criteria determined by the Independent Trustees for this purpose using data provided by Strategic Insight Mutual Fund Research and Consulting, LLC (Strategic Insight), an independent third party. In all quintile rankings referred to below, first quintile is most favorable to the Fund's shareowners. To the extent applicable, the Trustees also considered the impact of transfer agency, sub-transfer agency, and other non-management fee expenses on the expense ratios of the Fund. The Trustees noted that they separately review the Fund's transfer agency, sub-transfer agency and intermediary arrangements and that the results of the most recent such review were considered in the consideration of the Fund's expense ratio. The Trustees considered that the Fund's management fee as of September 30, 2016 was in the fourth quintile relative to the management fees paid by other funds in its Morningstar category for the comparable period. The Trustees considered that the Fund's management fee was approximately four basis points higher than the median management fee paid by other funds in its Morningstar category. The Trustees also considered the breakpoint in the management fee schedule and the reduced fee rate above a certain asset level. The Trustees considered that the expense ratio of the Fund's Class A shares as of September 30, 2016 was in the first quintile relative to its Morningstar category and in the first quintile relative to its Strategic Insight peer group, in 36 Pioneer U.S. Government Money Market Fund | Semiannual Report | 6/30/17 each case for the comparable period. The Trustees noted that Amundi Pioneer was waiving fees and/or reimbursing expenses in order to limit the ordinary operating expenses of the Fund and maintain a positive yield. The Trustees reviewed management fees charged by Amundi Pioneer and Amundi Pioneer Institutional to institutional and other clients, including publicly offered European funds sponsored by Amundi Pioneer's affiliates, unaffiliated U.S. registered investment companies (in a sub-advisory capacity), and unaffiliated foreign and domestic separate accounts. The Trustees also considered Amundi Pioneer's costs in providing services to the Fund and Amundi Pioneer's and Amundi Pioneer Institutional's costs in providing services to the other clients and considered the differences in management fees and profit margins for fund and non-fund services. In evaluating the fees associated with Amundi Pioneer's and Amundi Pioneer Institutional's client accounts, the Trustees took into account the respective demands, resources and complexity associated with the Fund and other client accounts. The Trustees noted that in some instances the fee rates for those clients were lower than the management fee for the Fund and considered that, under both the Current Management Agreement and the New Management Agreement, Amundi Pioneer would perform additional services for the Fund that it does not provide to those other clients or services that are broader in scope, including oversight of the Fund's other service providers and activities related to compliance and the extensive regulatory and tax regimes to which the Fund is subject. The Trustees also considered the different risks associated with Amundi Pioneer's management of the Fund and Amundi Pioneer's and Amundi Pioneer Institutional's management of the other client accounts. The Trustees concluded that the management fee payable by the Fund to Amundi Pioneer was reasonable in relation to the nature and quality of the services to be provided by Amundi Pioneer. Profitability The Trustees considered information provided by Amundi Pioneer regarding the profitability of Amundi Pioneer with respect to the advisory services provided by Amundi Pioneer to the Fund, including the methodology used by Amundi Pioneer in allocating certain of its costs to the management of the Fund. The Trustees also considered Amundi Pioneer's profit margin in connection with the overall operation of the Fund. They further reviewed the financial results, including the profit margins, realized by Amundi Pioneer and Amundi Pioneer Institutional from non-fund businesses. The Trustees considered Amundi Pioneer's profit margins with respect to the Fund in comparison to the limited industry data available and noted that the profitability of any adviser was affected by numerous factors, including its Pioneer U.S. Government Money Market Fund | Semiannual Report | 6/30/17 37 organizational structure and method for allocating expenses. The Trustees concluded that Amundi Pioneer's profitability with respect to the management of the Fund was not unreasonable. Economies of Scale The Trustees considered Amundi Pioneer's views relating to economies of scale in connection with the Pioneer Funds as fund assets grow and the extent to which any such economies of scale are shared with the Fund and Fund shareholders. The Trustees recognize that economies of scale are difficult to identify and quantify, and that, among other factors that may be relevant, are the following: fee levels, expense subsidization, investment by Amundi Pioneer in research and analytical capabilities and Amundi Pioneer's commitment and resource allocation to the Fund. The Trustees noted that profitability also may be an indicator of the availability of any economies of scale, although profitability may vary for other reasons including due to reductions in expenses. The Trustees concluded that economies of scale, if any, were being appropriately shared with the Fund. Other Benefits The Trustees considered the other benefits that Amundi Pioneer enjoys from its relationship with the Fund. The Trustees considered the character and amount of fees paid or to be paid by the Fund, other than under the Current Management Agreement or the New Management Agreement, for services provided by Amundi Pioneer and its affiliates. The Trustees further considered the revenues and profitability of Amundi Pioneer's businesses other than the Fund business. To the extent applicable, the Trustees also considered the benefits to the Fund and to Amundi Pioneer and its affiliates from the use of "soft" commission dollars generated by the Fund to pay for research and brokerage services. The Trustees considered that following the completion of the Transaction, Amundi Pioneer will be the principal U.S. asset management business of Amundi, and that Amundi's worldwide asset management business will manage over $1.38 trillion in assets (including the Pioneer Funds). This may create opportunities for Amundi Pioneer, Amundi Pioneer Institutional and Amundi that derive from Amundi Pioneer's relationships with the Fund, including Amundi's ability to market the services of Amundi Pioneer globally. The Trustees noted that Amundi Pioneer may have access to additional research capabilities as a result of the Transaction and Amundi's enhanced global presence that may contribute to an increase of the overall scale of Amundi Pioneer. The Trustees considered that Amundi Pioneer and the Fund are expected to receive reciprocal intangible benefits from the relationship, including mutual brand recognition and, for the Fund, direct and indirect 38 Pioneer U.S. Government Money Market Fund | Semiannual Report | 6/30/17 access to the resources of a large global asset manager. The Trustees concluded that any such benefits received by Amundi Pioneer as a result of its relationship with the Fund were reasonable. Conclusion After consideration of the factors described above as well as other factors, the Trustees, including the Independent Trustees, concluded that the New Management Agreement and the Interim Management Agreement for the Fund, including the fees payable thereunder, were fair and reasonable and voted to approve the New Management Agreement and the Interim Management Agreement, and to recommend that shareholders approve the New Management Agreement.

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.

N/A (h) Disclose whether the registrants audit committee of the board of trustees has considered whether the provision of non-audit services that were rendered to the registrants 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.

(a) Disclose the conclusions of the registrant's principal executive and principal financials officers, or persons performing similar functions, regarding the effectiveness of the registrant's disclosure controls and procedures (as defined in Rule 30a-3(c) under the Act (17 CFR 270.30a-3(c))) as of a date within 90 days of the filing date of the report that includes the disclosure required by this paragraph, based on the evaluation of these controls and procedures required by Rule 30a-3(b) under the Act (17 CFR 270.30(a)-3(b) and Rules 13a-15(b) or 15d-15(b) under the Exchange Act (17 CFR 240.13a-15(b) or 240.15d-15(b)).

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. (a) File the exhibits listed below as part of this Form.

EX-99 3 CodeofEthics.txt CODE OF ETHICS FOR SENIOR OFFICERS POLICY This Code of Ethics for Senior Officers (this "Code") sets forth the policies, practices and values expected to be exhibited by Senior Officers of the Pioneer Funds (collectively, the "Funds" and each, a "Fund"). This Code does not apply generally to officers and employees of service providers to the Funds, including Pioneer Investment Management, Inc. ("Pioneer"), unless such officers and employees are also Senior Officers. The term "Senior Officers" shall mean the principal executive officer, principal financial officer, principal accounting officer and controller of the Funds, although one person may occupy more than one such office. Each Senior Officer is identified by title in Exhibit A to this Code. The Chief Compliance Officer ("CCO") of the Pioneer Funds is primarily responsible for implementing and monitoring compliance with this Code, subject to the overall supervision of the Board of Trustees of the Funds (the "Board"). The CCO has the authority to interpret this Code and its applicability to particular situations. Any questions about this Code should be directed to the CCO or his or her designee. PURPOSE The purposes of this Code are to: . Promote honest and ethical conduct, including the ethical handling of actual or apparent conflicts of interest between personal and professional relationships; . Promote full, fair, accurate, timely and understandable disclosure in reports and documents that the Fund files with, or submits to, the Securities and Exchange Commission ("SEC") and in other public communications made by the Fund; ------------------------------------------------------------------------------- 1 Last revised January 17, 2014 . Promote compliance with applicable laws and governmental rules and regulations; . Promote the prompt internal reporting of violations of the Code to an appropriate person or persons identified in the Code; and . Establish accountability for adherence to the Code. Each Senior Officer should adhere to a high standard of business ethics and should be sensitive to situations that may give rise to actual as well as apparent conflicts of interest. RESPONSIBILITIES OF SENIOR OFFICERS Conflicts of Interest A "conflict of interest" occurs when a Senior Officer's private interests interfere in any way - or even appear to interfere - with the interests of or his/her service to a Fund. A conflict can arise when a Senior Officer takes actions or has interests that may make it difficult to perform his or her Fund work objectively and effectively. Conflicts of interest also arise when a Senior Officer or a member of his/her family receives improper personal benefits as a result of the Senior Officer's position with the Fund. Certain conflicts of interest arise out of the relationships between Senior Officers and the Fund and already are subject to conflict of interest provisions in the Investment Company Act of 1940, as amended (the "ICA"), and the Investment Advisers Act of 1940, as amended (the "IAA"). For example, Senior Officers may not individually engage in certain transactions (such as the purchase or sale of securities or other property) with the Funds because of their status as "affiliated persons" of the Funds. The Fund's and Pioneer's compliance programs and procedures are designed to prevent, or identify and correct, violations of these provisions. This Code does not, and is not intended to, repeat or replace such policies and procedures, and such conflicts fall outside of the parameters of this Code. Although typically not presenting an opportunity for improper personal benefit, conflicts arise as a result of the contractual relationship between the Fund and Pioneer because the Senior Officers are officers or employees of both. As a result, this Code recognizes that Senior Officers will, in the normal course of their duties (whether formally for a Fund or for Pioneer, or for both), be involved in establishing policies and implementing decisions that will have different effects on Pioneer and the Fund. The participation of Senior Officers in such activities is inherent in the contractual relationship between a Fund and Pioneer and is consistent with the performance by the Senior Officers of their duties as officers of the Fund and, if addressed in conformity with the provisions of the ICA and the IAA, will be deemed to have been handled ethically. In addition, it is recognized by the Board that Senior Officers may also be officers of investment companies other than the Pioneer Funds. Other conflicts of interest are covered by this Code, even if such conflicts of interest are not subject to provisions of the ICA or the IAA. In reading the following examples of conflicts of interest under this Code, Senior Officers should keep in mind that such a list cannot ever be exhaustive or cover every possible ------------------------------------------------------------------------------- 2 Last revised January 17, 2014 scenario. It follows that the overarching principle is that the personal interest of a Senior Officer should not be placed improperly before the interest of a Fund. Each Senior Officer must: . Not use his or her personal influence or personal relationships improperly to influence investment decisions or financial reporting by a Fund whereby the Senior Officer would benefit personally to the detriment of the Fund; . Not cause a Fund to take action, or fail to take action, for the individual personal benefit of the Senior Officer rather than the benefit of the Fund; and . Report at least annually any affiliations or other relationships that give rise to conflicts of interest. Any material conflict of interest situation should be approved by the CCO, his or her designee or the Board. Examples of these include: . Service as a director on the board of any public or private company; . The receipt of any gift with a value in excess of an amount established from time to time by Pioneer's Business Gift and Entertainment Policy from any single non-relative person or entity. Customary business lunches, dinners and entertainment at which both the Senior Officer and the giver are present, and promotional items of insignificant value are exempt from this prohibition; . The receipt of any entertainment from any company with which a Fund has current or prospective business dealings unless such entertainment is business-related, reasonable in cost, appropriate as to time and place, and not so frequent as to raise any question of impropriety; . Any ownership interest in, or any consulting or employment relationship with, any of a Fund's service providers other than its investment adviser, principal underwriter, administrator or any affiliated person thereof; and . A direct or indirect financial interest in commissions, transaction charges or spreads paid by a Fund for effecting portfolio transactions or for selling or redeeming shares other than an interest arising from the Senior Officer's employment, such as compensation or equity ownership. ------------------------------------------------------------------------------- 3 Last revised January 17, 2014 Corporate Opportunities Senior Officers may not (a) take for themselves personally opportunities that are discovered through the use of a Fund's property, information or position; (b) use a Fund's property, information, or position for personal gain; or (c) compete with a Fund. Senior Officers owe a duty to the Funds to advance their legitimate interests when the opportunity to do so arises. Confidentiality Senior Officers should maintain the confidentiality of information entrusted to them by the Funds, except when disclosure is authorized or legally mandated. Confidential information includes all non-public information that might be of use to competitors, or harmful to the Funds, if disclosed. Fair dealing with Fund shareholders, suppliers, and competitors Senior Officers should endeavor to deal fairly with the Funds' shareholders, suppliers, and competitors. Senior Officers should not take unfair advantage of anyone through manipulation, concealment, abuse of privileged information, misrepresentation of material facts, or any other unfair-dealing practice. Senior Officers should not knowingly misrepresent or cause others to misrepresent facts about a Fund to others, whether within or outside the Fund, including to the Board, the Funds' auditors or to governmental regulators and self-regulatory organizations. Compliance with Law Each Senior Officer must not knowingly violate any law, rule and regulation applicable to his or her activities as an officer of the Funds. In addition, Senior Officers are responsible for understanding and promoting compliance with the laws, rules and regulations applicable to his or her particular position and by persons under the Senior Officer's supervision. Senior Officers should endeavor to comply not only with the letter of the law, but also with the spirit of the law. Disclosure Each Senior Officer should familiarize himself or herself with the disclosure requirements generally applicable to the Funds. Each Senior Officer should, to the extent appropriate within his or her area of responsibility, consult with other officers of the Funds and Pioneer with the goal of promoting full, fair, accurate, timely and understandable disclosure in the reports and documents a Fund files with, or submits to, the SEC and in other public communications made by the Funds. INITIAL AND ANNUAL CERTIFICATIONS Upon becoming a Senior Officer the Senior Officer is required to certify that he or she has received, read, and understands this Code. On an annual basis, each Senior Officer must certify that he or she has complied with all of the applicable requirements of this Code. ------------------------------------------------------------------------------- 4 Last revised January 17, 2014 ADMINISTRATION AND ENFORCEMENT OF THE CODE Report of Violations Pioneer relies on each Senior Officer to report promptly if he or she knows of any conduct by a Senior Officer in violation of this Code. All violations or suspected violations of this Code must be reported to the CCO or a member of Pioneer's Legal and Compliance Department. Failure to do so is itself a violation of this Code. Investigation of Violations Upon notification of a violation or suspected violation, the CCO or other members of Pioneer's Compliance Department will take all appropriate action to investigate the potential violation reported. If, after such investigation, the CCO believes that no violation has occurred, the CCO and Compliance Department is not required to take no further action. Any matter the CCO believes is a violation will be reported to the Independent Trustees. If the Independent Trustees concur that a violation has occurred, they will inform and make a recommendation to the full Board. The Board shall be responsible for determining appropriate action. The Funds, their officers and employees, will not retaliate against any Senior Officer for reports of potential violations that are made in good faith and without malicious intent. The CCO or his or her designee is responsible for applying this Code to specific situations in which questions are presented under it and has the authority to interpret this Code in any particular situation. The CCO or his or her designee shall make inquiries regarding any potential conflict of interest. Violations and Sanctions Compliance with this Code is expected and violations of its provisions will be taken seriously and could result in disciplinary action. In response to violations of the Code, the Board may impose such sanctions as it deems appropriate within the scope of its authority over Senior Officers, including termination as an officer of the Funds. Waivers from the Code The Independent Trustees will consider any approval or waiver sought by any Senior Officer. The Independent Trustees will be responsible for granting waivers, as appropriate. Any change to or waiver of this Code will, to the extent required, be disclosed as provided by SEC rules. OTHER POLICIES AND PROCEDURES This Code shall be the sole Code of Ethics adopted by the Funds for purposes of Section 406 of the Sarbanes-Oxley Act and the rules and forms applicable to registered investment companies thereunder. The Funds', Pioneer's, and Pioneer Funds Distributor, Inc.'s Codes of Ethics under Rule 17j-1 under the ICA and Rule 204A-1 of the IAA are separate requirements applying to the Senior Officers and others, and are not a part of this Code. To the extent any other policies and procedures of the Funds, Pioneer or Pioneer ------------------------------------------------------------------------------- 5 Last revised January 17, 2014 Fund Distributor, Inc. overlap or conflict with the provisions of the this Code, they are superseded by this Code. SCOPE OF RESPONSIBILITIES A Senior Officer's responsibilities under this Code are limited to Fund matters over which the Senior Officer has direct responsibility or control, matters in which the Senior Officer routinely participates, and matters with which the Senior Officer is otherwise involved. In addition, a Senior Officer is responsible for matters of which the Senior Officer has actual knowledge. AMENDMENTS This Code other than Exhibit A may not be amended except in a writing that is specifically approved or ratified by a majority vote of the Board, including a majority of the Independent Trustees. CONFIDENTIALITY All reports and records prepared or maintained pursuant to this Code will be considered confidential and shall be maintained and protected accordingly. Except as otherwise required by law or this Code, such matters shall not be disclosed to anyone other than the Board and their counsel or to Pioneer's Legal and Compliance Department. INTERNAL USE This Code is intended solely for the internal use by the Funds and does not constitute an admission, by or on behalf of any Fund, as to any fact, circumstance, or legal conclusion. ------------------------------------------------------------------------------- 6 Last revised January 17, 2014 EXHIBIT A - SENIOR OFFICERS OF THE PIONEER FUNDS President (Principal Executive Officer) Treasurer (Principal Financial Officer) Code of Ethics for Senior Officers -------------------------------------------------------------------------------
