A disparate global economic landscape has formed, with the U.S. facing prospects for continued growth, while questions abound regarding the outlook for other regions. Employment, household income, and corporate profits have been rising in the U.S. and inflation pressures remain low. However, many countries across Europe as well as Japan face muted growth. In addition, a variety of factors have clouded the outlook for countries such as Russia and Brazil and China's investment-driven economy continues to slow. Monetary policies of major central banks are diverging, reflecting different economic conditions. With the U.S. economy no longer in need of extraordinary stimulus, the Federal Reserve Board may be closer to raising short-term interest rates. Conversely, the European Central Bank and the Bank of Japan are likely to be adding, not removing, stimulus. While we anticipate continued growth for the U.S., the outlook is far from certain, nor is the outlook for other regions necessarily dire. It remains to be seen how weakness outside the U.S. will affect global growth and whether easing monetary policies in other regions will spur an economic recovery. While these economic conditions may lead to increasing volatility in 2015, we believe the opportunity for investors to earn attractive returns will persist. However, in an environment where interest rates remain low and equity valuations have been buoyed by an extended bull market, we believe it is imperative investors adhere to a disciplined investment approach that is consistent with one's goals and objectives, being mindful of the tradeoff between risk and return. Since 1928 Pioneer's investment professionals have been focused on identifying and capitalizing on investment opportunities that present themselves in a variety of ever changing market conditions, including those we face today. We seek returns consistent with our strategies' stated style and 2 Pioneer Solutions Funds| Semiannual Report | 1/31/15 objectives and consistent with our shareholders' expectations, regardless of market conditions. We believe our shareowners benefit from the experience and tenure of our investment teams, the insights generated from extensive research resources and a commitment to prudent risk management that seeks to mitigate downside and preserve returns over time. 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, as we do when deploying strategies on behalf of our shareowners. 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. Any information in this shareowner report regarding market or economic trends or the factors influencing the Fund's historical or future performance are statements of opinion as of the date of this report. These statements should not be relied upon for any other purposes. Past performance is no guarantee of future results, and there is no guarantee that market forecasts discussed will be realized. Pioneer Solutions Funds | Semiannual Report | 1/31/15 3 Portfolio Management Discussion | 1/31/15 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 six-month period ended January 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 your overall approach with respect to management of the Funds' portfolios in the wake of the transition from the previous management team? 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 are now used to help manage exposures and the overall risk/reward profiles of each Fund. Importantly, each Fund is now managed with an eye toward the allocation of a "risk budget," rather than according to a straightforward asset allocation approach. This change reflects the fact that the majority of the risk embedded in an equally weighted bond and equity portfolio is normally concentrated within the equity component of the portfolio. 4 Pioneer Solutions Funds| Semiannual Report | 1/31/15 Q How would you characterize the economic and market backdrop during the six-month period ended January 31, 2015? A As the period opened in August 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 between the U.S., Europe and Russia over the latter nation's incursion into the Ukraine; in addition, the Israeli-Palestinian conflict briefly 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 growth model. The United States stood out as the primary engine of growth globally, as economic activity rebounded over the second half of 2014 after an exceptionally harsh winter likely caused a temporary slowdown earlier in the year. U.S. inflation remained subdued and, with employment conditions improving but still weak by many measures, the U.S. Federal Reserve (the Fed) signaled that there was no urgency on its part with respect to hiking short-term interest rates. As the six-month period progressed, market conditions were increasingly dominated by a collapse in oil prices, which was caused by many factors, including the outlook for both weakened global demand and continued strong supply. Lower oil prices were a positive for consumers in many countries, including the U.S., but for those emerging markets nations whose economies are highly dependent on oil revenues, the drop in prices created a strain on finances. For example, Russia's economy, already laboring under the weight of economic sanctions imposed by the West in response to events in the Ukraine, felt the pressure of lower oil prices as the ruble plummeted in relation to other leading currencies; this situation contributed to the already heightened geopolitical uncertainty. Against that backdrop, U.S. dollar-denominated assets were favored by investors, and that helped to drive further declines in U.S. interest rates. For the six-month period, global equities, as measured by the MSCI World ND Index, returned -1.39%, underperforming the U.S. equity market, as measured by the S&P 500 Index, which returned 4.36%. Emerging markets equities lagged equities in developed markets, as the MSCI Emerging Markets ND Index finished the period decidedly negative, returning -9.05%. Within the U.S. market, growth stocks notably outperformed their value counterparts. Domestic bonds returned 4.36% for the six-month period, as measured by the Barclays Aggregate Bond Index, a common measure of the U.S. bond market. Pioneer Solutions Funds | Semiannual Report | 1/31/15 5 Q What were the considerations and tactical shifts that you applied in allocating the Funds' assets during the six-month period ended January 31, 2015? A The six-month period was a transitional one for the Funds as we implemented a number of new positions. In particular, on the fixed-income side of the Funds' portfolios, we sought to add duration and corresponding exposure to interest-rate changes, 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 interest-rate exposure, while trimming the portfolios' exposure to lower-rated, high-yield bond funds. The rationale for the shift is that we expect any increase in interest-rate levels over the near term to be modest, in view of the continued efforts of global central banks to support their national and, in the case of the European Central Bank, regional economies. In addition, the immediate prospects appear limited for any sharp upturn in global economic growth that would lead to a spike in longer-term rates. As a result, we view the incremental income available from longer-term bonds as favorable in relation to the associated interest-rate risk. Overall, we assumed a more constructive stance towards equities in the Funds' portfolios during the period. The Funds' relative exposure to U.S. equities was modestly increased, and we trimmed holdings of domestic funds focused on small- and mid-cap stocks in favor of large-cap equity fund exposure. In addition, the Funds' exposure to European equities was increased during the period, as we view the region as favorably valued and positioned to benefit from central-bank stimulus and, longer-term, from economic reform efforts. Q The Funds now have the ability to invest in derivatives. Did you use derivatives as part of your investment strategy during the six-month period ended January 31, 2015, and did those positions have a material effect on performance? A We did use derivatives in order 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 country's economy, 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 economy and markets. The positions had a negligible effect on the Fund's performance during the timeframe covered by this report. 6 Pioneer Solutions Funds| Semiannual Report | 1/31/15 Q What factors are you watching most closely as you determine the strategy for the Funds going forward? A We would not find it surprising to see continued high levels of financial market volatility going forward. Geopolitical risks remain heightened, major central banks are pursuing conflicting policies, and reform efforts hang in the balance in a number of key economies. We anticipate that valuation opportunities will be presented as markets react to headlines and speculation with respect to all of these factors. In addition, given the slackened conditions in most major economies, we have positioned the Funds to take advantage of what should be relatively stable interest-rate levels over the near term. This includes both our willingness to assume interest-rate risk on the bond side of the Funds' portfolios as well as an overall positive view on equities relative to bonds. With respect to emerging markets, given the divergence in conditions across those economies, we are looking to reduce the Funds' overall exposure in favor of a more targeted approach. In particular, we see India and China as having the most favorable conditions among emerging markets economies. Both countries are enormous importers of oil and are undergoing government-reform efforts. We will continue to closely monitor the economic backdrop as we manage the Funds' portfolios within their strategic asset allocation and risk guidelines. Pioneer Solutions Funds | Semiannual Report | 1/31/15 7 Please refer to the Schedule of Investments on pages 31-36 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. A Solutions Fund's performance depends 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 Fund's 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 Fund's 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 Fund 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 portfolio 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. The Fund may invest in 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 Fund may use derivatives, such as options, futures, inverse floating rate obligations, swaps, and others, which can be illiquid, may disproportionately increase losses, and have a potentially large impact on Fund performance. Derivatives may have a leveraging effect on the Fund. 8 Pioneer Solutions Funds| Semiannual Report | 1/31/15 The Fund may invest in credit default swaps, which may in some cases be illiquid, and they increase credit risk since the fund has exposure to both the issuer of the referenced obligation and the counterparty to the credit default swap. The Fund and some of the underlying funds employ leverage, which increases the volatility of investment returns and subjects the Fund to magnified losses if an underlying fund's investments decline in value. The Fund 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 fund 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 fund holds cash un-invested, the fund will not earn income on the cash and the fund's yield will go down. These risks may increase share price volatility. There is no assurance that these and other strategies used by the Fund will be successful. Please see the prospectus for a more complete discussion of the Fund's risks. Before making an investment in any fund, you should consider all the risks associated with it. Please see the Fund Reviews beginning on page 9 for information on specific weightings and performance for each of the funds. Before investing, consider the product's investment objectives, risks, charges and expenses. Contact your advisor or Pioneer Investments for a prospectus or summary prospectus containing this information. Read it carefully.

Pioneer Solutions Funds | Semiannual Report | 1/31/15 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.

These combined totals were 1.38%, 2.12% and 1.35% for Class A, Class C and Class Y shares, respectively. These combined ratios were multiplied by the average account value over the period, and then multiplied by 184/365 (to reflect the one-half year period) to calculate the "Expenses Paid During Period" in the table above. 12 Pioneer Solutions Funds| Semiannual Report | 1/31/15 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.

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 Growth Fund Based on actual returns from August 1, 2014 through January 31, 2015. -------------------------------------------------------------------------------- Share Class A C Y -------------------------------------------------------------------------------- Beginning Account $1,000.00 $1,000.00 $1,000.00 Value on 8/1/14 -------------------------------------------------------------------------------- Ending Account Value $ 997.60 $ 994.90 $ 999.20 (after expenses) on 1/31/15 -------------------------------------------------------------------------------- Expenses Paid $ 7.20 $ 10.56 $ 5.59 During Period* -------------------------------------------------------------------------------- * Expenses are equal to the Fund's annualized net expense ratio plus the expense ratios of the underlying funds. These combined totals were 1.43%, 2.10% and 1.11% for Class A, Class C and Class Y shares, respectively. These combined ratios were multiplied by the average account value over the period, and then multiplied by 184/365 (to reflect the one-half year period) to calculate the "Expenses Paid During Period" in the table above. 16 Pioneer Solutions Funds| Semiannual Report | 1/31/15 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. Expenses Paid on a $1,000 Investment in Pioneer Solutions Growth Fund Based on a hypothetical 5% per year return before expenses, reflecting the period from August 1, 2014 through January 31, 2015. -------------------------------------------------------------------------------- Share Class A C Y -------------------------------------------------------------------------------- Beginning Account $1,000.00 $1,000.00 $1,000.00 Value on 8/1/14 -------------------------------------------------------------------------------- Ending Account Value $1,018.00 $1,014.62 $1,019.61 (after expenses) on 1/31/15 -------------------------------------------------------------------------------- Expenses Paid $ 7.27 $ 10.66 $ 5.65 During Period* -------------------------------------------------------------------------------- * Expenses are equal to the Fund's annualized net expense ratio plus the expense ratios of the underlying funds. These combined totals were 1.43%, 2.10% and 1.11% for Class A, Class C and Class Y shares, respectively. These combined ratios were multiplied by the average account value over the period, and then multiplied by 184/365 (to reflect the one-half year period) to calculate the "Expenses Paid During Period" in the table above.

The accompanying notes are an integral part of these financial statements. Pioneer Solutions Funds | Semiannual Report | 1/31/15 55 Notes to Financial Statements | 1/31/15 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 three 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 three classes of shares designated as Class A, Class C and Class Y shares. Each Fund ceased to offer Class B shares on November 10, 2014. Class B shares were converted to Class A shares as of the close of business on November 10, 2014. 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 dollar-weighted voting, a 56 Pioneer Solutions Funds| Semiannual Report | 1/31/15 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, which are consistent with those policies generally accepted in the investment company industry: 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 investments are not segregated in the Statement of Operations from the effects of changes in the market price of those securities but are included with the net realized and unrealized gain or loss on investments. Pioneer Solutions Funds | Semiannual Report | 1/31/15 57 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. The tax character of current year distributions paid will be determined at the end of the current taxable year. The tax character of distributions paid during the year ended July 31, 2014 was as follows: --------------------------------------------------------------------------- Ordinary Long-Term Fund Income Capital Gains Total --------------------------------------------------------------------------- Conservative Fund $1,928,874 $ -- $1,928,874 Moderate Fund 3,297,378 -- 3,297,378 Growth Fund 2,829,661 -- 2,829,661 Aggressive Fund 1,042,181 -- 1,042,181 The following table shows the components of distributable earnings on a federal income tax basis at July 31, 2014: -------------------------------------------------------------------------------- Other Net Undistributed Book/Tax Unrealized Ordinary Capital Loss Temporary Appreciation Fund Income Carryforward Differences (Depreciation) -------------------------------------------------------------------------------- Conservative Fund $ 558,475 $ (958,206) $ (875,880) $9,463,668 Moderate Fund 2,876,795 (22,069,624) (2,587,618) 47,571,275 Growth Fund 2,422,301 (31,221,768) (1,617,662) 61,630,012 Aggressive Fund 842,780 (24,127,121) (1,594,201) 39,762,873 58 Pioneer Solutions Funds| Semiannual Report | 1/31/15 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 six months ended January 31, 2015: --------------------------------------------------------------------------- Fund Amount --------------------------------------------------------------------------- Conservative Fund $ 6,995 Balanced Fund 21,155 Growth Fund 39,652 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 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. Pioneer Solutions Funds | Semiannual Report | 1/31/15 59 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 January 31, 2015, were as follows: --------------------------------------------------------------------------- Conservative Balanced Growth Fund Fund Fund --------------------------------------------------------------------------- Futures Collateral $85,182 $333,439 $592,024 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.

Change in Independent Registered Public Accounting Firm The Board of Trustees of the Trust, with the approval and recommendation of the Audit Committee, appointed Deloitte & Touche LLP to serve as the Trust's independent registered public accounting firm for the fiscal year ending July 31, 2014. Deloitte & Touche LLP replaces Ernst & Young LLP, which resigned as the Trust's independent registered public accounting firm, effective upon completion of the audit of the Trust's financial statements for the fiscal year ended July 31, 2013. Pioneer Solutions Funds | Semiannual Report | 1/31/15 77 During the periods that Ernst & Young LLP served as the Trust's independent registered public accounting firm, including the Trust's fiscal years ended July 31, 2013 and July 31, 2012, Ernst & Young LLP's reports on the financial statements of the Trust have not contained an adverse opinion or disclaimer of opinion and have not been qualified or modified as to uncertainty, audit scope or accounting principles. Further, there have been no disagreements with Ernst & Young LLP on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which, if not resolved to the satisfaction of Ernst & Young LLP would have caused Ernst & Young LLP to make reference to the subject matter of the disagreement in connection with its report on the financial statements. In addition, there have been no reportable events of the kind described in Item 304(a)(1)(v) of Regulation S-K under the Securities Exchange Act of 1934. 10. Conversion of Class B Shares As of the close of business on November 10, 2014 (the "Conversion Date"), all outstanding Class B shares of the Funds were converted to Class A shares. 11. 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.

(PIM) serves as the investment adviser to Pioneer Solutions - Conservative Fund (the Fund) pursuant to an investment advisory agreement between PIM and the Fund. In order for PIM to remain the investment adviser of the Fund, the Trustees of the Fund must determine annually whether to renew the investment advisory agreement for the Fund. The contract review process began in January 2014 as the Trustees of the Fund agreed on, among other things, an overall approach and timeline for the process. Contract review materials were provided to the Trustees in March 2014 and July 2014. Supplemental contract review materials were provided to the Trustees in September 2014. In addition, the Trustees reviewed and discussed the Fund's performance at regularly scheduled meetings throughout the year, and took into account other information related to the Fund provided to the Trustees at regularly scheduled meetings, in connection with the review of the Fund's investment advisory agreement. In March 2014, the Trustees, among other things, discussed the memorandum provided by Fund counsel that summarized the legal standards and other considerations that are relevant to the Trustees in their deliberations regarding the renewal of the investment advisory agreement, and reviewed and discussed the qualifications of the investment management teams, as well as the level of investment by the Fund's portfolio managers in the Fund. In July 2014, the Trustees, among other things, reviewed the Fund's management fee and total expense ratios, the financial statements of PIM and its parent companies, the profitability analyses provided by PIM, and possible economies of scale. The Trustees also reviewed the profitability of the institutional business of PIM and PIM's affiliate, Pioneer Institutional Asset Management, Inc. (together with PIM, "Pioneer"), as compared to that of PIM's fund management business, and considered the differences between the fees and expenses of the Fund and the fees and expenses of Pioneer's institutional accounts, as well as the different services provided by PIM to the Fund and by Pioneer to the institutional accounts. The Trustees further considered contract review materials in September 2014. At a meeting held on September 16, 2014, based on their evaluation of the information provided by PIM and third parties, the Trustees of the Fund, including the Independent Trustees voting separately, unanimously approved the renewal of the investment advisory agreement for another year. In considering the renewal of the investment advisory agreement, the Trustees considered various factors that they determined were relevant, including the 80 Pioneer Solutions Funds| Semiannual Report | 1/31/15 factors described below. In all quintile rankings referred to throughout this disclosure, first quintile is most favorable to the Fund's shareowners. The Trustees did not identify any single factor as the controlling factor in determining to approve the renewal of the agreement. Nature, Extent and Quality of Services The Trustees considered the nature, extent and quality of the services that had been provided by PIM to the Fund and would be provided by PIM to the Fund following the implementation of investment strategy changes for the Fund and PIM's assumption of direct responsibility for portfolio management decisions for the Fund. The Trustees took into account the investment objective and current and proposed strategy of the Fund. The Trustees reviewed the terms of the investment advisory agreement. The Trustees also reviewed PIM's investment approach for the Fund and its research process. The Trustees considered the resources of PIM and the personnel of PIM who provide investment management services to the Fund and would provide services following the implementation of investment strategy changes for the Fund. They also reviewed the amount of non-Fund assets managed by the portfolio managers of the Fund. The Trustees considered the non-investment resources and personnel of PIM involved in PIM's services to the Fund, including PIM's compliance and legal resources and personnel. The Trustees noted the substantial attention and high priority given by PIM's senior management to the Pioneer fund complex. The Trustees considered that PIM supervises and monitors the performance of the Fund's service providers and provides the Fund with personnel (including Fund officers) and other resources that are necessary for the Fund's business management and operations. The Trustees also considered that, as administrator, PIM is responsible for the administration of the Fund's business and other affairs. The Trustees considered the fees paid to PIM for the provision of administration services. Based on these considerations, the Trustees concluded that the nature, extent and quality of services that had been provided by PIM to the Fund were satisfactory and consistent with the terms of the investment advisory agreement. Performance of the Fund In considering the Fund's performance, the Trustees regularly review and discuss analysis and data prepared by PIM 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 with the performance of the Fund's benchmark index. They also discuss the Fund's performance with PIM on a regular basis. The Trustees confirmed that these regular reviews and discussions were factored into the Trustees' deliberations Pioneer Solutions Funds | Semiannual Report | 1/31/15 81 concerning the renewal of the advisory agreement. For purposes of their contract renewal deliberations, the Trustees considered the discussions held throughout the year regarding the Fund's performance and the performance results of the Fund over various time periods, including the Fund's performance results for periods ended June 30, 2014. The Trustees noted the Fund's relatively poor peer comparisons of total return over the 1-, 3- and 5-year periods, but indicated that they were satisfied with PIM's response to the Fund's performance issues. In particular, the Trustees noted that Ibbotson Associates, Inc. served as the Fund's sub-adviser for all periods under consideration. The Trustees noted that, in connection with the implementation of investment strategy changes for the Fund, PIM would assume direct responsibility for portfolio management decisions for the Fund. Management Fee and Expenses The Trustees considered information showing the fees and expenses of the Fund in comparison to the management fees and expense ratios of its peer group of funds as classified by Morningstar and also to the expense ratios of a peer group of funds selected on the basis of criteria determined by the Independent Trustees for this purpose using data provided by Strategic Insight Mutual Fund Research and Consulting, LLC (Strategic Insight), an independent third party. The Trustees considered that the Fund's management fee for the twelve months ended June 30, 2014 was in the third quintile relative to the management fees paid by other funds in its Morningstar peer group for the comparable period. The Trustees also considered the breakpoints in the management fee schedule and the reduced fee rates above certain asset levels. The Trustees considered that the expense ratio of the Fund's Class A shares for the twelve months ended June 30, 2014 was in the fifth quintile relative to its Morningstar peer group and in the fourth quintile relative its Strategic Insight peer group, in each case for the comparable period. The Trustees 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. The Trustees noted the Fund's relatively small asset size compared to most of the other funds in its peer groups. They noted that the Fund's non-management fee operating expenses generally are spread over a smaller asset base than the other funds in the peer group, which results in these fees being significantly higher as a percentage of assets. The Trustees also considered information showing significant expense reimbursements by the sponsors of the other funds in the peer groups. 82 Pioneer Solutions Funds| Semiannual Report | 1/31/15 The Trustees reviewed management fees charged by Pioneer to institutional and other clients, including publicly offered European funds sponsored by affiliates of Pioneer, unaffiliated U.S. registered investment companies (in a sub-advisory capacity), and unaffiliated foreign and domestic separate accounts. The Trustees also considered PIM's costs in providing services to the Fund and Pioneer's costs in providing services to the other clients and considered the differences in management fees and profit margins for Fund and non-Fund services. In evaluating the fees associated with Pioneer's client accounts, the Trustees took into account the respective demands, resources and complexity associated with the Fund and client accounts. The Trustees noted that, in some instances, the fee rates for those clients were lower than the management fee for the Fund and considered that, under the investment advisory agreement with the Fund, PIM performs additional services for the Fund that it does not provide to those other clients or services that are broader in scope, including oversight of the Fund's other service providers and activities related to compliance and the extensive regulatory and tax regimes to which the Fund is subject. The Trustees also considered the different entrepreneurial risks associated with PIM's management of the Fund and Pioneer's management of the other client accounts. The Trustees concluded that the management fee payable by the Fund to PIM was reasonable in relation to the nature and quality of the services provided by PIM to the Fund. Profitability The Trustees considered information provided by PIM regarding the profitability of PIM with respect to the advisory services provided by PIM to the Fund, including the methodology used by PIM in allocating certain of its costs to the management of the Fund. The Trustees also considered PIM's profit margin in connection with the overall operation of the Fund. They further reviewed the financial results realized by PIM and its affiliates from non-fund businesses. The Trustees considered PIM's profit margins with respect to the Fund in comparison to the limited industry data available and noted that the profitability of any adviser was affected by numerous factors, including its organizational structure and method for allocating expenses. The Trustees concluded that PIM's profitability with respect to the management of the Fund was not unreasonable. Economies of Scale The Trustees considered PIM's views relating to economies of scale in connection with the Pioneer Funds as fund assets grow and the extent to which any such economies of scale are shared with funds and fund shareholders. The Trustees noted the breakpoints in the management fee schedule. The Trustees recognize that economies of scale are difficult to Pioneer Solutions Funds | Semiannual Report | 1/31/15 83 identify and quantify, and that, among other factors that may be relevant, are the following: fee levels, expense subsidization, investment by PIM in research and analytical capabilities and PIM's commitment and resource allocation to the Fund. The Trustees noted that profitability also may be an indicator of the availability of any economies of scale, although profitability may vary for other reasons including due to reductions in expenses. The Trustees concluded that economies of scale, if any, were being appropriately shared with the Funds. Other Benefits The Trustees considered the other benefits to PIM from its relationship with the Fund. The Trustees considered the character and amount of fees paid by the Fund, other than under the investment advisory agreement, for services provided by PIM and its affiliates. The Trustees further considered the revenues and profitability of PIM's businesses other than the fund business. Pioneer is the principal U.S. asset management business of Pioneer Global Asset Management, the worldwide asset management business of UniCredit Group, which manages over $150 billion in assets (including the Funds). Pioneer and the Funds receive reciprocal intangible benefits from the relationship, including mutual brand recognition and, for the Funds, direct and indirect access to the resources of a large global asset manager. The Trustees concluded that any such benefits received by Pioneer as a result of its relationship with the Funds were reasonable and their consideration of the advisory agreement between the Fund and PIM and the fees thereunder were unaffected by Pioneer's possible receipt of any such intangible benefits. Conclusion After consideration of the factors described above as well as other factors, the Trustees, including all of the Independent Trustees, concluded that the investment advisory agreement between PIM and the Fund, including the fees payable thereunder, was fair and reasonable and voted to approve the proposed renewal of the investment advisory agreement for the Fund. 84 Pioneer Solutions Funds| Semiannual Report | 1/31/15 Pioneer Solutions - Balanced Fund Approval of Investment Advisory Agreement Pioneer Investment Management, Inc.

The Trustees concluded that the management fee payable by the Fund to PIM was reasonable in relation to the nature and quality of the services provided by PIM to the Fund. Profitability The Trustees considered information provided by PIM regarding the profitability of PIM with respect to the advisory services provided by PIM to the Fund, including the methodology used by PIM in allocating certain of its costs to the management of the Fund. The Trustees also considered PIM's profit margin in connection with the overall operation of the Fund. They further reviewed the financial results realized by PIM and its affiliates from non-fund businesses. The Trustees considered PIM's profit margins with respect to the Fund in comparison to the limited industry data available and noted that the profitability of any adviser was affected by numerous factors, including its organizational structure and method for allocating expenses. The Trustees concluded that PIM's profitability with respect to the management of the Fund was not unreasonable. Economies of Scale The Trustees considered PIM's views relating to economies of scale in connection with the Pioneer Funds as fund assets grow and the extent to which any such economies of scale are shared with funds and fund shareholders. The Trustees noted the breakpoints in the management fee schedule. The Trustees recognize that economies of scale are difficult to Pioneer Solutions Funds | Semiannual Report | 1/31/15 93 identify and quantify, and that, among other factors that may be relevant, are the following: fee levels, expense subsidization, investment by PIM in research and analytical capabilities and PIM's commitment and resource allocation to the Fund. The Trustees noted that profitability also may be an indicator of the availability of any economies of scale, although profitability may vary for other reasons including reductions in expenses. The Trustees concluded that economies of scale, if any, were being appropriately shared with the Funds. Other Benefits The Trustees considered the other benefits to PIM from its relationship with the Fund. The Trustees considered the character and amount of fees paid by the Fund, other than under the investment advisory agreement, for services provided by PIM and its affiliates. The Trustees further considered the revenues and profitability of PIM's businesses other than the fund business. Pioneer is the principal U.S. asset management business of Pioneer Global Asset Management, the worldwide asset management business of UniCredit Group, which manages over $150 billion in assets (including the Funds). Pioneer and the Funds receive reciprocal intangible benefits from the relationship, including mutual brand recognition and, for the Funds, direct and indirect access to the resources of a large global asset manager. The Trustees concluded that any such benefits received by Pioneer as a result of its relationship with the Funds were reasonable and their consideration of the advisory agreement between the Fund and PIM and the fees thereunder were unaffected by Pioneer's possible receipt of any such intangible benefits. Conclusion After consideration of the factors described above as well as other factors, the Trustees, including all of the Independent Trustees, concluded that the investment advisory agreement between PIM and the Fund, including the fees payable thereunder, was fair and reasonable and voted to approve the proposed renewal of the investment advisory agreement for the Fund. 94 Pioneer Solutions Funds| Semiannual Report | 1/31/15 Trustees, Officers and Service Providers Trustees Advisory Trustee Thomas J.

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.

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.
