As 2015 began, market expectations were that the Fed would likely begin raising interest rates by the middle of the year, but a sluggish gross domestic product report in the first calendar quarter as well as relatively benign inflation and wage growth contributed to the Fed's taking a more cautionary approach and delaying the start of its rate-hike cycle. At the same time, however, the U.S. labor market has continued its robust improvement, moving the Fed closer to declaring victory on one of its main monetary policy objectives -- full employment. Meanwhile, global economic activity has continued to diverge, with developed economies experiencing above-trend growth and most emerging markets economies lagging the rest of the world. The slower pace of economic activity in the emerging markets has been most evident in China, as the country's economy continues to undergo a long, potentially painful adjustment from investment-led growth to consumption-oriented growth. This divergence in global economic cycles is likely to continue for some time, and we would expect an increased level of volatility as global capital markets and policymakers adjust. Pioneer Investments believes that investors in today's environment can potentially benefit from the consistent and disciplined investment approach we have used since our founding in 1928. We focus on identifying value across global markets using proprietary research, careful risk management, and a long-term perspective. Our ongoing goal is to produce compelling returns consistent with the stated objectives of our investment products, and with our shareowners' expectations. We believe our shareowners can benefit from the experience and tenure of our investment teams as well as the insights generated from our extensive research process. 2 Pioneer Solutions Funds | Annual Report | 7/31/15 As always, and particularly during times of market uncertainty, we encourage you to work with your financial advisor to develop an overall investment plan that addresses both your short-and long-term goals, and to implement such a plan in a disciplined manner. We greatly appreciate your trust in us in the past and look forward to continuing to serve you in the future. Sincerely, /s/ Lisa M. Jones Lisa M. Jones President and CEO Pioneer Investment Management USA, Inc.

Pioneer Solutions Funds | Annual Report | 7/31/15 3 Portfolio Management Discussion | 7/31/15 Effective November 14, 2014, the Pioneer Ibbotson Aggressive Allocation Fund merged into Pioneer Ibbotson Growth Allocation Fund. The Fund was then renamed Pioneer Solutions - Growth Fund. Also on November 14, 2014, Pioneer Ibbotson Conservative Allocation Fund was renamed Pioneer Solutions - Conservative Fund, and Pioneer Ibbotson Moderate Allocation Fund was renamed Pioneer Solutions - Balanced Fund, and investment adviser duties for all three funds were transitioned from Ibbotson Associates to Pioneer Investments. In the following interview, portfolio managers John O'Toole and Paul Weber discuss the market environment and investment strategies that applied to the Pioneer Solutions Funds for the 12-month period ended July 31, 2015. Working out of Pioneer's Dublin, Ireland office, Mr. O'Toole, Head of Multi-Asset Portfolio Management at Pioneer, Mr. Weber, Head of Fund Research & Manager Selection at Pioneer, and Salvatore Buono, Head of Strategy Alignment and Structured Products at Pioneer, are responsible for the day-to-day management of the portfolios. Q Can you review the approach you've taken with respect to the Funds' asset allocations since your team assumed management responsibilities last November? A As under the previous managers, the assets of each Fund are allocated within broad strategic guidelines designed to address a particular investor risk profile. In seeking to gain the desired exposures in the portfolios to U.S. equities, international equities, bonds and cash, we utilize a broad selection of mutual funds. Under the new investment approach, we typically incorporate into the portfolios a substantial representation of carefully selected mutual funds managed by Pioneer, and by other third-party managers. In addition, derivative positions, which we discuss in more detail later in this report, are now used to help manage exposures and the overall risk/reward profile for each Fund. Importantly, each Fund is now managed with an eye toward the allocation of a "risk budget," rather than under a straightforward asset allocation approach. This reflects the fact that the majority of the risk embedded in an equally weighted bond and equity portfolio is concentrated within the equity component. Q How would you characterize the economic and market backdrop during the 12-month period ended July 31, 2015? A As the period opened in the summer of 2014, financial markets were unsettled by a range of geopolitical and macroeconomic concerns. On the geopolitical front, the rise of ISIS carried the potential to disrupt stability in the Middle East and the global energy supply, even as tensions deepened 4 Pioneer Solutions Funds | Annual Report | 7/31/15 between the U.S. and Russia over the latter's incursion into the Ukraine. In addition, the Israeli-Palestinian conflict briefly re-escalated. On the economic front, concerns over global growth transformed into fears of outright deflation in Europe and Japan. At the same time, markets watched closely to gauge the impact of China's efforts to reform its economy in the direction of a more sustainable model. The United States stood as the primary engine of global growth, as domestic economic activity rebounded over the second half of 2014 following an exceptionally harsh winter. Additionally, U.S. inflation remained subdued and, with employment conditions still weak by many measures, the U.S. Federal Reserve System (the Fed) signaled that there was no urgency with respect to hiking short-term rates. As the period progressed, market conditions were increasingly dominated by a collapse in oil prices in late 2014/early 2015, caused by an outlook for both weakened global demand and strong supply. While positive for consumers in many countries, including the U.S., the decline in oil prices severely strained the finances of a number of emerging markets nations, which are highly dependent on oil revenues, including Russia. With Russia already laboring under economic sanctions imposed by the West in response to events in the Ukraine, the ruble plummeted in relation to other leading currencies, adding to already heightened geopolitical uncertainty. Against that backdrop, U.S. dollar-denominated assets came to be favored by investors, helping to drive further declines in U.S. interest rates. Energy-related stocks and credit-sensitive securities also suffered through significant slumps, while other areas of the U.S. capital markets benefited from the anticipated positive effects of lower energy prices upon consumers. In addition, a second consecutive harsh winter in the U.S. contributed to a disappointing gross domestic product (GDP) report for the first calendar quarter of 2015, which further clouded the global economic growth picture. Risk sentiment in the markets stabilized, somewhat, as the final months of the 12-month period progressed, as oil prices bounced back from their early 2015 lows and the European Central Bank (ECB) announced that it would undertake a quantitative easing bond-purchasing program. Meanwhile, U.S. GDP rebounded in the second quarter and the domestic employment situation continued to improve. Equities generally traded within a certain range over the last several months of the period as investors monitored U.S. economic growth for any guidance as to the likely timing of the Fed's first interest-rate increase, and supportive action by overseas central banks (like the ECB) was offset by the market's growing concerns over Greece's ability to stay in the euro due to the country's sovereign-debt crisis. Pioneer Solutions Funds | Annual Report | 7/31/15 5 Over the full 12 months, global equities, as measured by the Morgan Stanley Capital International (MSCI) World ND Index, returned 4.93%. By region, U.S. equities, as measured by the Standard & Poor's 500 Index, returned 11.19%, outperforming international equities, which returned 0.15% as gauged by the MSCI Europe, Australasia, Far East Index. Emerging markets equities lagged developed markets, as the MSCI Emerging Markets Index finished the period in deeply negative territory, returning -13.07%. Among U.S. equities, growth stocks notably outperformed their value counterparts. With regard to fixed income, the Barclays Aggregate Bond Index, the most popular measure of the performance of the U.S. bond market, returned 2.82% over the 12-month period. Q What were the considerations and tactical shifts that you applied in allocating the Funds' assets during the 12-month period ended July 31, 2015? A The 12 months were a transitional period for the Funds, as we implemented a number of new positions. In particular, on the fixed-income side of the portfolios, we sought to add duration and corresponding exposure to interest-rate moves, while dialing back credit sensitivity to some degree. (Duration is a measure of the sensitivity of the price - the value of principal - of a fixed-income investment to a change in interest rates, expressed as a number of years.) We did this by adding positions in a number of bond funds that actively manage their portfolios' interest-rate exposure, while trimming positions in lower-rated, high-yield bond funds. Our rationale for the shift is our expectation that any rise in interest-rate levels over the near term will be modest, in light of the continued efforts of global central banks to support their countries' economies. In addition, the prospects appear limited for any immediate, sharp upturn in economic growth that would lead to a spike in longer-term rates. As a result, we view the incremental income available from investments in longer-term bonds as favorable relative to the associated interest-rate risk. While we did increase duration over the course of the 12-month period, the portfolios still had a short-duration orientation relative to the fixed-income market (as measured by the Barclays Aggregate Bond Index), and that acted as a constraint on the Funds' returns as interest-rate levels declined. With regard to equities, we maintained a constructive stance in the Funds for most of the 12-month period; however, towards the end of the period, we did reduce equity exposure across the Funds, mainly due to valuation concerns against a backdrop of ongoing geopolitical uncertainty. In particular, exposure to U.S. equities was trimmed -- after we had increased equity exposure earlier in the period -- given the extended upward run 6 Pioneer Solutions Funds | Annual Report | 7/31/15 most domestic stock indices have experienced. We have maintained a focus on larger-cap stocks within the U.S., as they are typically less dependent on domestic growth prospects. We increased the Funds' overall exposure to European equities during the period, as we viewed stocks in the region as favorably valued and positioned to benefit from central-bank stimulus and, longer-term, from economic reform efforts. Q The Funds have the ability to invest in derivatives. Did you use derivatives as part of your investment strategy during the 12-month period ended July 31, 2015, and did those positions have a material effect on performance? A We will use derivatives regularly in order to efficiently execute strategies, including to gain or trim market exposures and to implement relative value trades. In particular, during the period we used derivatives to give the portfolios some exposure to the broad Japanese stock market. Japan's central bank has been putting forth extraordinary efforts to stimulate the economy there, and the country has been a particular beneficiary of the drop in oil prices. In addition, we believe the announced plans to structurally reform the economy, while somewhat halting to date in terms of execution, hold promise for Japan's long-term outlook as well as its markets. The positions were a positive factor with respect to the Fund's performance, as Japanese stocks rose during the 12-month period. Q What factors are you watching most closely as you determine your investment strategies for the Funds going forward? A The Fed has done its best to prepare investors for the inevitable unwinding of its extraordinarily accommodative policy stance. However, it would still not surprise us to see market interest rates react strongly to an announcement of an increase in the benchmark Federal funds rate. We have been taking steps to try to protect the portfolios against such a scenario, including adding a significant position in mutual funds managed under alternative, less-directional approaches, as well as considering an increase in the Funds' exposure to syndicated floating-rate bank loans, the performance of which would likely benefit from a rising-rate environment. While we are somewhat cautious with respect to credit-sensitive securities, we anticipate that valuation opportunities will arise as markets react to headlines and speculation about such factors as Fed policy, economic growth in China, and geopolitical developments. Accordingly, we will be looking to selectively add credit-sensitive exposure to the portfolios when we believe the Funds are being paid for the additional assumed risk. On the equity side of things, we view Europe and Japan as offering better value than the U.S. stock market, especially given the strong measures taken by central banks in those areas. We are taking a highly targeted approach with respect to the emerging markets, given the divergence in economic Pioneer Solutions Funds | Annual Report | 7/31/15 7 conditions across those economies. We continue to see the major economies of India and China as having relatively favorable conditions, despite the recent problems in China, as both countries are enormous importers of oil -- which remains cheap compared with a year ago -- and both are undergoing reform efforts. Broadly, the Funds are positioned based on our anticipation that overall global economic growth will remain positive, if underwhelming. We will continue to closely monitor the global economic backdrop as we actively manage the broadly diversified* portfolios within their strategic asset allocation and risk guidelines. * Diversification does not assure a profit nor protect against loss. Please refer to the Schedule of Investments on pages 36-49 for a full listing of fund securities. Each portfolio in Pioneer Solutions Funds is a "fund-of-funds" which seeks to achieve its investment objectives by primarily investing in mainly funds managed by Pioneer or one of its affiliates, rather than direct position in securities. The Solutions Funds' performance depend on the adviser's skill in determining the strategic asset allocations, the mix of underlying funds, as well as the performance of those underlying funds. The underlying funds' performance may be lower than the performance of the asset class that they were selected to represent. In addition to the Funds' operating expenses, investors will indirectly bear the operating expenses of investments in any underlying funds. Each of the underlying funds has its own investment risks. At times, the Funds' investments may represent industries or sectors that are interrelated or have common risks, making them more susceptible to any economic, political, or regulatory developments or other risks affecting those industries and sectors. Investments in equity securities are subject to price fluctuation. When interest rates rise, the prices of fixed income securities in the fund will generally fall. Conversely, when interest rates fall, the prices of fixed income securities in the fund will generally rise. Investments in the Funds are subject to possible loss due to the financial failure of issuers of underlying securities and their inability to meet their debt obligations. Investing in foreign and/or emerging markets securities involves risks relating to interest rates, currency exchange rates, economic, and political conditions. The portfolios invests in REIT securities, the value of which can fall for a variety of reasons, such as declines in rental income, fluctuating interest rates, poor property management, environmental liabilities, uninsured damage, increased competition, or changes in real estate tax laws. 8 Pioneer Solutions Funds | Annual Report | 7/31/15 The Funds may invest in underlying funds with exposure to commodities. The value of commodity-linked derivatives may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, factors affecting a particular industry or commodity, international economic, political and regulatory developments, supply and demand, and governmental regulatory policies. The Funds may use derivatives, such as options, futures, inverse floating rate obligations, swaps, and others, which can be illiquid, may disproportionately increase losses, and have a potentially large impact on fund performance. Derivatives may have a leveraging effect on the Fund. The Funds may invest in credit default swaps, which may in some cases be illiquid, and they increase credit risk since the fund has exposure to both the issuer of the referenced obligation and the counterparty to the credit default swap. The Funds and some of the underlying funds employ leverage, which increases the volatility of investment returns and subjects the Funds to magnified losses if an underlying fund's investments decline in value. The Funds and some of the underlying funds may employ short selling, a speculative strategy. Unlike the possible loss on a security that is purchased, there is no limit on the amount of loss on an appreciating security that is sold short. The value of the investments held by the Funds for cash management or temporary defensive purposes may be affected by market risks, changing interest rates, and by changes in credit ratings of the investments. If the Funds hold cash that is uninvested, the Funds will not earn income on the cash and the Funds' yields will go down. These risks may increase share price volatility. There is no assurance that these and other strategies used by the Funds will be successful. Please see the prospectus for a more complete discussion of the Funds' risks. Before making an investment in any fund, you should consider all the risks associated with it. Please see the Fund Reviews beginning on page 10 for information on specific weightings and performance for each of the funds. Before investing, consider the product's investment objectives, risks, charges and expenses.

Pioneer Solutions Funds | Annual Report | 7/31/15 11 Comparing Ongoing Fund Expenses Pioneer Solutions - Conservative Fund 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 Solutions Conservative Fund Based on actual returns from February 1, 2015 through July 31, 2015. -------------------------------------------------------------------------------- Share Class A C R Y -------------------------------------------------------------------------------- Beginning Account $1,000.00 $1,000.00 $1,000.00 $1,000.00 Value on 2/1/15* -------------------------------------------------------------------------------- Ending Account Value $1,014.72 $1,010.59 $1,003.40 $1,012.73 (after expenses) on 7/31/15 -------------------------------------------------------------------------------- Expenses Paid $ 6.79 $ 10.47 $ 1.34 $ 8.13 During Period** -------------------------------------------------------------------------------- * Period begins July 1, 2015 (commencement of operations) for Class R shares. ** Expenses are equal to the Fund's annualized net expense ratio, plus the ratio of the underlying funds. These combined totals were 1.36%, 2.10%, 1.58% and 1.63% for Class A, Class C, Class R and Class Y shares, respectively. These combined totals were multiplied by the average account value over the period, and then multiplied by 181/365 (31/365 for Class R shares)(to reflect the one half-year period). 12 Pioneer Solutions Funds | Annual Report | 7/31/15 Hypothetical Example for Comparison Purposes The table below provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the tables are meant to highlight your ongoing costs only and do not reflect any transaction costs, such as sales charges (loads) that are charged at the time of the transaction. Therefore, the table below is useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds. In addition, if these transaction costs were included, your costs would have been higher.

The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the tables are meant to highlight your ongoing costs only and do not reflect any transaction costs, such as sales charges (loads) that are charged at the time of the transaction. Therefore, the table below is useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds. In addition, if these transaction costs were included, your costs would have been higher.

Pioneer Solutions Funds | Annual Report | 7/31/15 15 Comparing Ongoing Fund Expenses Pioneer Solutions - Growth Fund 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.

Investment return and principal value will fluctuate, and shares, when redeemed, may be worth more or less than their original cost. The performance shown for Class R shares for the period prior to the commencement of operations of Class R shares on July 1, 2015, is the net asset value performance of the Fund's Class A shares, which has not been restated to reflect any differences in expenses, including Rule 12b-1 fees applicable to Class A shares. Since fees for Class A shares generally are higher than those of Class R shares, the performance of Class R shares prior to their inception would have been higher than the performance shown. For the period beginning July 1, 2015, the actual performance of Class R shares is reflected. Class R shares are not subject to sales charges and are available for limited groups of eligible investors, including institutional investors. All results are historical and assume the reinvestment of dividends and capital gains. Other share classes are available for which performance and expenses will differ. Performance results reflect any applicable expense waivers in effect during the periods shown. Without such waivers Fund performance would be lower. Waivers may not be in effect for all funds. Certain fee waivers are contractual through a specified period. Otherwise, fee waivers can be rescinded at any time. See the prospectus and financial statements for more information. The net expense ratio reflects the contractual expense limitation currently in effect through December 1, 2016, for Class R shares. There can be no assurance that Pioneer will extend the expense limitation beyond such time. Please see the prospectus and financial statements for more information.

The accompanying notes are an integral part of these financial statements. 70 Pioneer Solutions Funds | Annual Report | 7/31/15 Notes to Financial Statements | 7/31/15 1. Organization and Significant Accounting Policies Pioneer Asset Allocation Trust (formerly known as Pioneer Ibbotson Asset Allocation Series) (the "Trust") is organized as a Delaware statutory trust and is registered with the Securities and Exchange Commission under the Investment Company Act of 1940 (the 1940 Act) as an open-end management investment company. The Trust consists of three separate funds (each, a "Fund," and collectively, the "Funds"), each issuing four classes of shares as follows: Pioneer Solutions - Conservative Fund (formerly Pioneer Ibbotson Conservative Allocation Fund) ("Conservative Fund") Pioneer Solutions - Growth Fund (formerly Pioneer Ibbotson Growth Allocation Fund) ("Growth Fund") Pioneer Solutions - Balanced Fund (formerly Pioneer Ibbotson Moderate Allocation Fund) ("Balanced Fund") The investment objective of each of the Conservative Fund, the Growth Fund and the Balanced Fund is to seek long-term capital growth and current income. Each Fund is a "fund of funds." Each Fund seeks to achieve its investment objective by investing primarily in other funds ("underlying funds"). Each Fund may also invest directly in securities and use derivatives. Each Fund invests mainly in funds managed by Pioneer Investment Management, Inc. (PIM) . Each Fund may also invest in unaffiliated mutual funds or exchange-traded funds (ETFs). The Funds indirectly pay a portion of the expenses incurred by underlying funds. Consequently, an investment in the Funds entails more direct and indirect expenses than direct investment in the applicable underlying funds. Each Fund offers four classes of shares designated as Class A, Class C, Class R and Class Y shares. Class B shares were converted to Class A shares as of the close of business on November 10, 2014. Class R shares for each Fund commenced operations on July 1, 2015. Each class of shares represents an interest in the same portfolio of investments of each 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 each Fund gives the Board the flexibility to specify either per -share voting or dollar-weighted voting when submitting matters for shareholder approval. Under per-share voting, each share of a class of a Fund is entitled to one vote. Under Pioneer Solutions Funds | Annual Report | 7/31/15 71 dollar-weighted voting, a shareholder's voting power is determined not by the number of shares owned, but by the dollar value of the shares on the record date. Each share class has exclusive voting rights with respect to matters affecting only that class, including with respect to the distribution plan for that class. There is no distribution plan for Class Y shares. The financial statements have been prepared in conformity with U.S. generally accepted accounting principles that require the management of the Funds to, among other things, make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of income and expenses during the reporting period. Actual results could differ from these estimates. The following is a summary of significant accounting policies followed by the Trust in preparation of its financial statements: A. Security Valuation Security transactions are recorded as of the trade date. The net asset value is computed once daily, on each day the New York Stock Exchange (NYSE) is open, as of the close of regular trading on the NYSE. In computing the net asset value, holdings of mutual fund shares are valued at the net asset value of each fund held. Cash may include overnight time deposits at approved financial institutions. B. Investment Income and Transactions Dividend income and realized capital gain distributions from investment company shares held are recorded on the ex-dividend date. Temporary cash investments are valued at amortized cost which approximates market value. Gains and losses on sales of investments are calculated on the identified cost method for both financial reporting and federal income tax purposes. C. Foreign Currency Translation The books and records of the Funds 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 72 Pioneer Solutions Funds | Annual Report | 7/31/15 investments are not segregated in the Statement of Operations from the effects of changes in the market price of those securities but are included with the net realized and unrealized gain or loss on investments. D. Forward Foreign Currency Contracts The Funds may enter into forward foreign currency contracts (contracts) for the purchase or sale of a specific foreign currency at a fixed price on a future date. All contracts are marked to market daily at the applicable exchange rates, and any resulting unrealized appreciation or depreciation are recorded in the Funds' financial statements. The Funds record realized gains and losses at the time a contract is offset by entry into a closing transaction or extinguished by delivery of the currency. Risks may arise upon entering into these contracts from the potential inability of counterparties to meet the terms of the contracts and from unanticipated movements in the value of foreign currencies relative to the U.S. dollar (see Note 5). E. Federal Income Taxes It is the Funds' policy to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all taxable income and net realized capital gains, if any, to shareholders. Therefore, no federal income tax provisions are required. Tax years for the prior three fiscal years remain subject to examination by federal and state tax authorities. The amounts and characterizations of distributions to shareowners for financial reporting purposes are determined in accordance with federal income tax rules. Therefore, the sources of the Funds' distributions may be shown in the accompanying financial statements as from or in excess of net investment income or as from net realized gain on investment transactions, or as from paid-in capital, depending on the type of book/tax differences that may exist. At July 31, 2015, the Funds reclassified the following amounts to reflect permanent book/tax differences. These adjustments have no impact on the net assets or results of operations. -------------------------------------------------------------------------------- Conservative Fund Balanced Fund Growth Fund -------------------------------------------------------------------------------- Undistributed net investment income $ 83,026 $ 728,440 $ 1,387,423 Accumulated net realized gain on investments (83,027) (728,440) (1,387,423) Paid-in Capital 1 -- -- Pioneer Solutions Funds | Annual Report | 7/31/15 73 During the year ended July 31, 2015, Conservative Fund, Balanced Fund and Growth Fund were able to utilize capital loss carryforwards of $958,206, $22,069,624, and $55,454,390 (of which $24,232,622 was acquired from the reorganization with Pioneer Ibbotson Aggressive Allocation Fund on November 14, 2014), respectively, to offset net realized gains. The tax character of distributions paid during the years ended July 31, 2015 and July 31, 2014 were as follows: -------------------------------------------------------------------------------- 2015 2014 -------------------------------------------------------------------------------- Conservative Fund Distributions paid from: Ordinary income $1,771,130 $1,928,874 -------------------------------------------------------------------------------- Total $1,771,130 $1,928,874 ================================================================================ Balanced Fund Distributions paid from: Ordinary income $6,001,453 $3,297,378 -------------------------------------------------------------------------------- Total $6,001,453 $3,297,378 ================================================================================ Growth Fund Distributions paid from: Ordinary income $9,424,958 $2,829,661 -------------------------------------------------------------------------------- Total $9,424,958 $2,829,661 ================================================================================ The following table shows the components of distributable earnings on a federal income tax basis at July 31, 2015: -------------------------------------------------------------------------------- Conservative Fund Balanced Fund Growth Fund -------------------------------------------------------------------------------- Undistributed ordinary income $ 599,190 $ 2,232,856 $ 740,515 Undistributed long-term capital gains 6,622,753 14,493,043 22,130,952 Unrealized appreciation/ depreciation 479,067 9,963,474 30,598,001 -------------------------------------------------------------------------------- Total $7,701,010 $26,689,373 $53,469,468 ================================================================================ The differences between book-basis and tax-basis net unrealized appreciation are attributable to the tax deferral of losses on wash sales. F. Fund Shares The Funds record sales and repurchases of Fund shares as of trade date. Pioneer Funds Distributor, Inc. (PFD), the principal underwriter for the Funds and a wholly owned indirect subsidiary of UniCredit S.p.A.(UniCredit), earned the following in underwriting commissions on the sale of Class A shares during the year ended July 31, 2015: -------------------------------------------------------------------------------- Fund Amount -------------------------------------------------------------------------------- Conservative Fund $14,942 Balanced Fund 39,466 Growth Fund 73,676 74 Pioneer Solutions Funds | Annual Report | 7/31/15 G. Class Allocations Income, common expenses and realized and unrealized gains and losses are calculated at the Fund level and allocated daily to each class of shares based on its respective percentage of adjusted net assets at the beginning of the day. Distribution fees are calculated based on the average daily net asset value attributable to Class A and Class C shares of each Fund, respectively (see Note 4). Class Y shares do not pay distribution fees. All expenses and fees paid to the transfer agent, Pioneer Investment Management Shareholder Services, Inc. (PIMSS), for its services are allocated among the class 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 each of the Funds with respect to each class of shares are calculated in the same manner and at the same time, except that net investment income dividends to Class A, Class B, Class C, Class R and Class Y shares of each Fund can reflect different transfer agent and distribution expense rates. H. Risks Some of the underlying funds can invest in either high yield securities or small/ emerging growth companies. Investments in these types of securities generally are subject to greater volatility than either higher-grade securities or more-established companies in more developed markets, respectively. The Funds' prospectus contains unaudited information regarding the Funds' principal risks. Please refer to that document when considering the Funds' principal risks. I. Futures Contracts The Funds may enter into futures transactions in order to attempt to hedge against changes in interest rates, securities prices and currency exchange rates or to seek to increase total return. Futures contracts are types of derivatives. All futures contracts entered into by the Funds are traded on a futures exchange. Upon entering into a futures contract, the Funds are required to deposit with a broker an amount of cash or securities equal to the minimum "initial margin" requirements of the associated futures exchange. The amount of cash deposited with the broker as collateral at July 31, 2015, were as follows: -------------------------------------------------------------------------------- Conservative Balanced Growth Fund Fund Fund -------------------------------------------------------------------------------- Futures Collateral $440,790 $1,434,519 $2,566,071 Pioneer Solutions Funds | Annual Report | 7/31/15 75 Subsequent payments for futures contracts ("variation margin") are paid or received by the Funds, depending on the daily fluctuation in the value of the contracts, and are recorded by the Funds as unrealized appreciation or depreciation. When the contract is closed, the Funds realize a gain or loss equal to the difference between the opening and closing value of the contract as well as any fluctuation in foreign currency exchange rates where applicable. The use of futures contracts are subject to market risk, interest rate risk and currency exchange rate risk. Changes in value of the contracts may not directly correlate to the changes in value of the underlying securities. The average value of contracts open during the year ended July 31, 2015, were as follows: -------------------------------------------------------------------------------- Conservative Balanced Growth Fund Fund Fund -------------------------------------------------------------------------------- $172,093 $1,794,641 $4,787,399 At July 31, 2015, open futures contracts were as follows: Pioneer Solutions - Conservative Fund -------------------------------------------------------------------------------- Number of Unrealized Contracts Settlement Appreciation Type Long/(Short) Month Value (Depreciation) -------------------------------------------------------------------------------- Euro Stoxx Banks 80 9/15 $ 690,108 $ (6,628) FTSE/JSE Top 40 (5) 9/15 (183,522) (8,981) MSCI Asia Pacific PC EX (6) 9/15 (228,732) 8,630 MSCI Energy Index 23 9/15 686,851 (35,836) MSCI World IX (16) 9/15 (761,920) (12,124) Nikkei 225 (SGX) 8 9/15 663,196 (1,130) Stoxx 600 INSU (44) 9/15 (689,581) 4,330 MINI MSCI Emerging Markets (11) 12/15 (495,000) 58,493 -------------------------------------------------------------------------------- $(318,600) $ 6,754 -------------------------------------------------------------------------------- Pioneer Solutions - Balanced Fund -------------------------------------------------------------------------------- Number of Unrealized Contracts Settlement Appreciation Type Long/(Short) Month Value (Depreciation) -------------------------------------------------------------------------------- Euro Stoxx Banks 248 9/15 $ 2,139,335 $ (20,545) FTSE/JSE Top 40 (15) 9/15 (550,567) (26,944) MSCI Asia Pacific PC EX (16) 9/15 (609,952) 23,014 MSCI Energy Index 68 9/15 2,030,691 (106,785) MSCI World IX (48) 9/15 (2,285,760) (36,373) Nikkei 225 (SGX) 47 9/15 3,896,279 (6,638) Stoxx 600 INSU (137) 9/15 (2,147,105) 13,481 MINI MSCI Emerging Markets (35) 12/15 (1,575,000) 186,113 -------------------------------------------------------------------------------- $ 897,921 $ 25,323 -------------------------------------------------------------------------------- 76 Pioneer Solutions Funds | Annual Report | 7/31/15 Pioneer Solutions - Growth Fund -------------------------------------------------------------------------------- Number of Unrealized Contracts Settlement Appreciation Type Long/(Short) Month Value (Depreciation) -------------------------------------------------------------------------------- Euro Stoxx Banks 425 9/15 $ 3,666,199 $ (35,209) FTSE/JSE Top 40 (25) 9/15 (917,612) (44,906) MSCI Asia Pacific PC EX (28) 9/15 (1,067,416) 40,274 MSCI Energy Index 116 9/15 3,464,120 (181,649) MSCI World IX (80) 9/15 (3,809,600) (60,622) Nikkei 225 (SGX) 123 9/15 10,196,646 (17,371) Stoxx 600 INSU (234) 9/15 (3,667,318) 23,027 MINI MSCI Emerging Markets (59) 12/15 (2,655,000) 313,733 -------------------------------------------------------------------------------- $ 5,210,019 $ 37,277 -------------------------------------------------------------------------------- J. Option Writing The Fund may write put and covered call options to seek to increase total return. When an option is written, the Fund receives a premium and becomes obligated to purchase or sell the underlying security at a fixed price upon the exercise of the option. When the Fund writes an option, an amount equal to the premium received by the Fund is recorded as a liability and is subsequently adjusted to the current value of the option written. Premiums received from writing options that expire unexercised are treated by the Fund on the expiration date as realized gains from investments. The difference between the premium and the amount paid on effecting a closing purchase transaction, including brokerage commissions, is also treated as a realized gain or, if the premium is less than the amount paid for the closing purchase transaction, as a realized loss. If a call option is exercised, the premium is added to the proceeds from the sale of the underlying security in determining whether the Fund has realized a gain or loss. The Fund as writer of an option bears the market risk of an unfavorable change in the price of the security underlying the written option. Written call and put option contracts outstanding at year end are listed at the end of the Fund's Schedule of Investments. The average value of written option contracts open during the year ended July 31, 2015 were as follows: -------------------------------------------------------------------------------- Conservative Balanced Growth Fund Fund Fund -------------------------------------------------------------------------------- $(29,842) $(94,746) $(175,609) Pioneer Solutions Funds | Annual Report | 7/31/15 77 Transactions in written options for the year ended July 31, 2015 are summarized as follows: Pioneer Solutions - Conservative Fund -------------------------------------------------------------------------------- Number of Premium Contracts Received -------------------------------------------------------------------------------- Options open at beginning of year -- $ -- Options opened (1,535) (263,334) Options exercised -- -- Options closed 1,167 153,734 Options expired 349 16,397 -------------------------------------------------------------------------------- Options open at end of year (19) $ (93,203) Pioneer Solutions - Balanced Fund -------------------------------------------------------------------------------- Number of Premium Contracts Received -------------------------------------------------------------------------------- Options open at beginning of year -- $ -- Options opened (4,456) (836,816) Options exercised -- -- Options closed 3,552 467,300 Options expired 827 48,348 -------------------------------------------------------------------------------- Options open at end of year (77) $ (321,168) Pioneer Solutions - Growth Fund -------------------------------------------------------------------------------- Number of Premium Contracts Received -------------------------------------------------------------------------------- Options open at beginning of year -- $ -- Options opened (7,616) (1,601,309) Options exercised -- -- Options closed 5,916 778,950 Options expired 1,382 80,504 -------------------------------------------------------------------------------- Options open at end of year (318) $ (741,855) K.

Upon the purchase of a call or put option, the premium paid by the Fund is included in the Statement of Assets and Liabilities as an investment. All premiums are marked-to-market daily, and any unrealized gains or losses are recorded in the Fund's financial statements. As the purchaser of an index option, the Fund has the right to receive a cash payment equal to any depreciation in the value of the index below the strike price of the option (in the case of a put) or equal to any appreciation in the value of the index over the strike price of the option (in the case of a call) as of the valuation date of the option. Premiums paid for purchased calls and put options which have expired are treated as 78 Pioneer Solutions Funds | Annual Report | 7/31/15 realized losses on investments in the Statement of Operations. Upon the exercise or closing of a purchased put option, the premium is offset against the proceeds on the sale of the underlying security or financial instrument in order to determine the realized gain or loss on investments. Upon the exercise or closing of a purchased call option, the premium is added to the cost of the security or financial instrument. The risk associated with purchasing options is limited to the premium originally paid. Purchased option contracts outstanding at year end are listed at the end of the Fund's Schedule of Investments. The average value of purchased options open during the year ended July 31, 2015 were as follows: -------------------------------------------------------------------------------- Conservative Balanced Growth Fund Fund Fund -------------------------------------------------------------------------------- $45,222 $145,564 $270,306 L. Credit Default Swap Agreements A credit default swap is a contract between a buyer of protection and a seller of protection against a pre -defined credit event. The Fund may sell or buy credit default swap contracts to seek to increase the Fund's income, or to attempt to hedge the risk of default on Fund securities. A credit default swap index is used to hedge risk or take a position on a basket of credit entities or indices. As a seller of protection, the Fund would be required to pay the notional (or other agreed-upon) value of the referenced debt obligation to the counterparty in the event of a default by a U.S. or foreign corporate issuer of a debt obligation, which would likely result in a loss to the Fund. In return, the Fund would receive from the counterparty a periodic stream of payments during the term of the contract provided that no event of default occurred. The maximum exposure of loss to the seller would be the notional value of the credit default swaps outstanding. If no default occurs, the Fund would keep the stream of payments and would have no payment obligation. The Fund may also buy credit default swap contracts in order to hedge against the risk of default of debt securities, in which case the Fund would function as the counterparty referenced above. When the Fund enters into a credit default swap contract, the protection buyer makes an upfront or periodic payment to the protection seller in exchange for the rights to receive a contingent payment. An upfront payment made by the Fund, as the protection buyer, is recorded as an asset in the Statement of Assets and Liabilities. Periodic payments received or paid by the Fund are recorded as realized gains or losses in the Statement of Operations. Credit default swap contracts are marked-to-market daily using valuations supplied by independent sources and the change in value, if any, is recorded as unrealized appreciation or depreciation in the Statement of Assets and Pioneer Solutions Funds | Annual Report | 7/31/15 79 Liabilities. Payments received or made as a result of a credit event or upon termination of the contract are recognized, net of the appropriate amount of the upfront payment, as realized gains or losses in the Statement of Operations. Certain swap contracts that are cleared through a central clearinghouse are referred to as centrally cleared swaps. All payments made or received by the Fund are pursuant to a centrally cleared swap contract with the central clearing party rather than the original counterparty. Upon entering into a centrally cleared swap contract, the Fund is required to make an initial margin deposit, either in cash or in securities. The daily change in value on open centrally cleared contracts is recorded as variation margin on centrally cleared swaps on the Statement of Assets and Liabilities. Credit default swap contracts involving the sale of protection may involve greater risks than if the Fund had invested in the referenced debt instrument directly. Credit default swap contracts are subject to general market risk, liquidity risk, counterparty risk and credit risk. If the Fund is a protection buyer and no credit event occurs, it will lose its investment. If the Fund is a protection seller and a credit event occurs, the value of the referenced debt instrument received by the Fund, together with the periodic payments received, may be less than the amount the Fund pays to the protection buyer, resulting in a loss to the Fund. There were no open credit default swap contracts at July 31, 2015. The average value of credit default swap contracts open during the year ended July 31, 2015 were as follows: -------------------------------------------------------------------------------- Conservative Balanced Growth Fund Fund Fund -------------------------------------------------------------------------------- $798 $2,440 $4,096 M. Inflation Rate Swap Contracts The Fund may enter into inflation rate swap contracts to attempt to hedge against inflation. Pursuant to the inflation rate swap agreement, the Fund negotiates with a counterparty to exchange a periodic stream of payments, based on a benchmark inflation index. One cash flow stream will typically be a floating rate payment linked to the specified inflation index while the other is typically a fixed interest rate. Inflation rate swap contracts are marked-to-market daily using valuations supplied by independent sources and the change in value, if any, is recorded as unrealized appreciation or depreciation in the Statement of Assets and Liabilities. Inflation rate swaps are normally issued on a zero coupon basis where all payments compound during the life of the contract and are netted upon the termination or maturity of the contract. Final payments received or paid by the Fund are recorded as realized gains or losses in the Statement of Operations. Inflation rate swap contracts are subject to movements in interest rates. 80 Pioneer Solutions Funds | Annual Report | 7/31/15 Open inflation rate swap contracts at July 31, 2015 are listed in the Schedule of Investments.

Interest Rate Swap Contracts The Fund may enter into interest rate swaps to attempt to hedge against interest rate fluctuations or to enhance its income. Pursuant to the interest rate swap agreement, the Fund negotiates with a counterparty to exchange a periodic stream of payments based on a benchmark interest rate. One cash flow stream will typically be a floating rate payment based upon the specified floating benchmark interest rate while the other is typically a fixed interest rate. Payment flows are usually netted against each other, with the difference being paid by one party to the other on a monthly basis. Periodic payments received or paid by the Fund are recorded as realized gains or losses in the Statement of Operations. Interest rate swap contracts are marked-to-market daily using valuations supplied by independent sources and the change in value, if any, is recorded as unrealized appreciation or depreciation in the Statement of Assets and Liabilities.

Pioneer Solutions Funds | Annual Report | 7/31/15 99 9. Reorganization Information On November 14, 2014 ("Closing Date"), Pioneer Ibbotson Aggressive Allocation Fund ("Aggressive Fund") was reorganized into Growth Fund. The purpose of this transaction was to combine two funds (managed by PIM) with similar investment objectives and strategies. This tax-free reorganization was accomplished by exchanging the assets and liabilities of the Aggressive Fund for shares of the Growth Fund. Shareowners holding Class A, Class C and Class Y shares of the Aggressive Fund received Class A, Class C and Class Y shares of the Growth Fund, respectively, in the reorganization. The investment portfolio of the Aggressive Fund, with an aggregate value of $128,596,529 and an identified cost of $88,931,762 at November 14, 2014, was the principal asset acquired by the Growth Fund. For financial reporting purposes, assets received and shares issued by the Growth Fund were recorded at net asset value, however, the cost basis of the investments received from the Aggressive Fund was carried forward to align ongoing reporting of the Growth Fund's realized and unrealized gains and losses with amounts distributable to shareowners for tax reporting purposes. 100 Pioneer Solutions Funds | Annual Report | 7/31/15 The following charts show the details of the reorganization as of the Closing Date: --------------------------------------------------------------------------------------------- Aggressive Fund Growth Fund Growth Fund (Pre-Reorganization) (Pre-Reorganization) (Post-Reorganization) --------------------------------------------------------------------------------------------- Net Assets Class A $105,417,866 $171,483,703 $276,901,569 Class C 22,944,724 64,868,995 87,813,719 Class Y 372,456 1,027,929 1,400,385 --------------------------------------------------------------------------------------------- Total Net Assets $128,735,046 $237,380,627 $366,115,673 --------------------------------------------------------------------------------------------- Shares Outstanding Class A 7,524,857 12,612,148 20,363,470 Class C 1,722,284 5,042,583 6,826,781 Class Y 26,428 74,140 101,013 --------------------------------------------------------------------------------------------- --------------------------------------------------------------------------------------------- Exchange Shares Issued Ratio in Reorganization --------------------------------------------------------------------------------------------- Class A 1.0301 7,751,322 Class C 1.0359 1,784,198 Class Y 1.0168 26,873 --------------------------------------------------------------------------------------------- --------------------------------------------------------------------------------------------- Unrealized Accumulated Appreciation on Gain (Loss) on Closing Date Closing Date --------------------------------------------------------------------------------------------- Aggressive $39,664,767 $(24,232,621) Growth $62,059,622 $(30,765,442) --------------------------------------------------------------------------------------------- Assuming the Reorganization had been completed on August 1, 2014, the beginning of the Fund's current fiscal period, the pro forma results of operations for the year ended July 31, 2015, are as follows: -------------------------------------------------------------------------------- Net Investment Income (Loss) $ 5,906,490 Net Realized and Unrealized Gains 11,597,253 -------------------------------------------------------------------------------- Change in Net Assets Resulting from Operations $17,503,743 -------------------------------------------------------------------------------- Because the combined investment portfolios have been managed as a single integrated portfolio since the reorganization was completed, it is not practical to separate the amounts of revenue and earnings of the Growth Fund that have been included in the Statements of Operations since the Reorganization was consummated. Pioneer Solutions Funds | Annual Report | 7/31/15 101 Report of Independent Registered Public Accounting Firm To the Board of Trustees of Pioneer Asset Allocation Trust (formerly, Pioneer Ibbotson Asset Allocation Series) and Shareowners of Pioneer Solutions - Conservative Fund, Pioneer Solutions - Growth Fund, and Pioneer Solutions - Balanced Fund (formerly, Pioneer Ibbotson Conservative Allocation Fund, Pioneer Ibbotson Growth Allocation Fund, and Pioneer Ibbotson Moderate Allocation Fund): -------------------------------------------------------------------------------- We have audited the accompanying statements of assets and liabilities of Pioneer Solutions - Conservative Fund, Pioneer Solutions - Growth Fund, and Pioneer Solutions - Balanced Fund (formerly, Pioneer Ibbotson Conservative Allocation Fund, Pioneer Ibbotson Growth Allocation Fund, and Pioneer Ibbotson Moderate Allocation Fund) (the "Funds") (each a portfolio constituting Pioneer Asset Allocation Trust (formerly, Pioneer Ibbotson Asset Allocation Series)), including the schedules of investments, as of July 31, 2015, and the related statement of operations for the year then ended and the statements of changes in net assets and the financial highlights for each of the two years in the period then ended. These financial statements and financial highlights are the responsibility of the Funds' management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. The financial highlights for the years ended July 31, 2013, 2012, and 2011 were audited by other auditors. Those auditors expressed an unqualified opinion on those financial statements and financial highlights in their report dated September 24, 2013. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. The Funds are not required to have, nor were we engaged to perform, an audit of their 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 Funds' internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of July 31, 2015, by correspondence with the custodian, brokers and agent banks; where replies were not received from brokers and agent banks, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of each of the Funds as of July 31, 2015, the results of its operations for the year then ended, and the changes in its net assets and the financial highlights for each of the two years in the period then ended, in conformity with accounting principles generally accepted in the United States of America. /s/ Deloitte & Touche LLP Boston, Massachusetts September 24, 2015 102 Pioneer Solutions Funds | Annual Report | 7/31/15 Additional Information (unaudited) PIM, the Fund's investment adviser, is currently an indirect, wholly-owned subsidiary of UniCredit. On April 23, 2015, UniCredit announced that it signed a preliminary and exclusive agreement with Banco Santander and affiliates of Warburg Pincus and General Atlantic (the "Private Equity Firms") with respect to Pioneer Investments ("Pioneer") and Santander Asset Management ("SAM") (the "Transaction"). The Transaction, as described in the UniCredit announcement, will entail the establishment of a holding company, with the name Pioneer Investments, to be owned by UniCredit (50%) and the Private Equity Firms (50% between them). The holding company will control Pioneer's U.S. operations, including the Adviser. The holding company also will own 66.7% of Pioneer's and SAM's combined operations outside the U.S., while Banco Santander will own directly the remaining 33.3% stake. The completion of the Transaction is subject to the signing of a definitive agreement, as well as certain regulatory and corporate approvals, and other conditions. Under the Investment Company Act of 1940, completion of the Transaction will cause the Fund's investment advisory agreement with the Adviser to terminate. In connection with the Transaction, the Fund's Board of Trustees will be asked to approve a new investment advisory agreement for the Fund. If approved by the Board, the Fund's new investment advisory agreement will be submitted to the shareholders of the Fund for their approval.

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.
