[LOGO] PIONEER Investments(R) - -------------------------------------------------------------------------------- An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- Contact your investment professional to discuss how the fund fits into your portfolio. - -------------------------------------------------------------------------------- Basic information about the fund Investment objective Capital growth. Principal investment strategies The fund invests at least 80% of its assets in equity securities. For purposes of the fund's investment policies, equity securities include common stocks, convertible debt and other equity instruments, such as exchange-traded funds (ETFs) that invest primarily in equity securities, depositary receipts, warrants, rights, equity interests in real estate investment trusts (REITs) and preferred stocks. The fund may invest up to 25% of its total assets in equity and debt securities of non-U.S. corporate issuers and debt securities of non-U.S. government issuers, including up to 10% of its assets in the securities of emerging markets issuers. The fund invests in non-U.S. securities to diversify its portfolio when they offer similar or greater potential for capital appreciation compared to U.S. securities. Pioneer Investment Management, Inc., the fund's investment adviser, seeks securities selling at reasonable prices or substantial discounts to their underlying values and then holds these securities until the market values reflect their intrinsic values. Pioneer evaluates a security's potential value, including the attractiveness of its market valuation, based on the company's assets and prospects for earnings and revenue growth. In making that assessment, Pioneer employs due diligence and fundamental research, an evaluation of the issuer based on its financial statements and operations. Pioneer relies on the knowledge, experience and judgment of its staff and the staff of its affiliates who have access to a wide variety of research. Pioneer focuses on the quality and price of individual issuers, not on economic sector or market-timing strategies. Factors Pioneer looks for in selecting investments include: o Estimated private market value in excess of current stock price. Private market value is the price an independent investor would pay to own the entire company o Above average potential for earnings and revenue growth o Management with demonstrated ability and commitment to the company o Low market valuations relative to earnings forecast, book value, cash flow and sales Principal risks of investing in the fund You could lose money on your investment or not make as much as if you invested elsewhere if: o The stock market goes down or performs poorly relative to other investments (this risk may be greater in the short term) o Value stocks fall out of favor with investors o The fund's investments do not have the growth potential originally expected 1 Basic information about the fund Risks of non-U.S. investments Investing in non-U.S. issuers may involve unique risks compared to investing in securities of U.S. issuers. These risks are more pronounced for issuers in emerging markets or to the extent that the fund invests significantly in one region or country. These risks may include: o Less information about non-U.S. issuers or markets may be available due to less rigorous disclosure or accounting standards or regulatory practices o Many non-U.S. markets are smaller, less liquid and more volatile. In a changing market, Pioneer may not be able to sell the fund's portfolio securities at times, in amounts and at prices it considers reasonable o Adverse effect of currency exchange rates or controls on the value of the fund's investments o The economies of non-U.S. countries may grow at slower rates than expected or may experience a downturn or recession o Economic, political and social developments may adversely affect the securities markets o Withholding and other non-U.S. taxes may decrease the fund's return Market segment risks To the extent the fund emphasizes, from time to time, investments in a market segment, the fund will be subject to a greater degree to the risks particular to the industries in that segment, and may experience greater market fluctuation, than a fund without the same focus. For example, industries in the financial segment, such as banks, insurance companies, broker-dealers and real estate investment trusts (REITs), may be sensitive to changes in interest rates and general economic activity and are subject to extensive government regulation. Industries in the technology segment, such as information technology, communications equipment, computer hardware and software, and office and scientific equipment, are subject to risks of rapidly evolving technology, short product lives, rates of corporate expenditures, falling prices and profits, competition from new market entrants, and general economic conditions. 2 The fund's past performance The bar chart and table indicate the risks of investing in the fund by showing how the fund has performed in the past. The fund's performance will vary from year to year. The performance of Class A shares for the period prior to the commencement of operations of Class A shares is the net asset value performance of the fund's Class P shares, which has been restated to reflect differences in any applicable sales charges, but not differences in expenses, including Rule 12b-1 fees applicable to Class A shares. The fund's past performance does not necessarily indicate how it will perform in the future. As a shareowner, you may lose or make money on your investment. Fund performance The chart shows the year-by-year performance of the fund's Class A shares. The chart does not reflect any sales charge you may pay when you buy or sell fund shares. Any sales charge will reduce your return. Class C shares will have different performance. Annual return Class A shares (%) (Year ended December 31) [The following data was represented as a bar chart in the printed material] '99 22.88 '00 15.38 '01 -11.86 '02 -22.18 '03 29.79 '04 9.53 '05 9.59 '06 11.38 The highest calendar quarterly return was 19.09% (03/31/2003 to 06/30/2003) The lowest calendar quarterly return was -18.36% (06/30/2002 to 09/30/2002) 3 Basic information about the fund Comparison with the Russell 1000 Index and the Russell 1000 Growth Index The table shows the average annual total returns for each class of the fund over time and compares these returns to the returns of the Russell 1000 Index and the Russell 1000 Growth Index. The Russell 1000 Index measures the performance of large-cap U.S. stocks. The Russell 1000 Growth Index measures the performance of large-cap U.S. growth stocks. The fund's benchmark has changed from the Russell 1000 Index to the Russell 1000 Growth Index. It is Pioneer's opinion that since the Russell 1000 Growth Index better reflects the fund's investment strategies, it is a more appropriate benchmark for the fund. Unlike the fund, the indices are not managed and do not incur expenses. The table: o Reflects sales charges applicable to the class o Assumes that you sell your shares at the end of the period o Assumes that you reinvest all of your dividends and distributions Average annual total return (%) (for periods ended December 31, 2006) Since Inception 1 Year 5 Years Inception Date - ------------------------------------------------------------------------------------------ Class A 3/16/98 Return before taxes 4.98 4.94 5.08 - ------------------------------------------------------------------------------------------ Return after taxes on distributions 3.26 4.37 4.30 - ------------------------------------------------------------------------------------------ Return after taxes on distributions and sale of shares 4.79 4.12 4.03 - ------------------------------------------------------------------------------------------ Class C 3/16/98 Return before taxes N/A N/A 5.07 - ------------------------------------------------------------------------------------------ Russell 1000 Index (reflects no deduction for taxes) 15.46 6.82 4.91* - ------------------------------------------------------------------------------------------ Russell 1000 Growth Index (reflects no deduction for taxes) 9.07 2.69 1.41** - ------------------------------------------------------------------------------------------ # Inception date of the fund's Class P shares. Class A and Class C shares commenced operations on March 10, 2006. * Since the inception of Class A shares. Class C shares: 10.50%. ** Since the inception of Class A shares. Class C shares: 5.80%. After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on the investor's tax situation and may differ from those shown, and the after-tax returns shown are not relevant to shareholders who hold fund shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts. After-tax returns for Class C shares will vary from the after-tax returns presented for Class A shares. 4 Fees and expenses This table describes the fees and expenses that you may pay if you buy and hold shares of the fund.

It assumes that: a) you invest $10,000 in the fund for the time periods shown, b) you reinvest all dividends and distributions, c) your investment has a 5% return each year, d) the fund's total operating expenses remain the same and e) Pioneer's contractual expense limitation is in effect for year one. Although your actual costs may be higher or lower, under these assumptions your costs would be: If you sell your shares If you do not sell your shares ---------------------------------- ------------------------------ Number of years you own your shares ---------------------------------------------------------------------- 1 3 5 10 1 3 5 10 - ------------------------------------------------------------------------------------ Class A $695 $1,025 $1,377 $2,367 $695 $1,025 $1,377 $2,367 - ------------------------------------------------------------------------------------ Class C 311 652 1,119 2,410 211 652 1,119 2,410 - ------------------------------------------------------------------------------------ 1 Class A purchases of $1 million or more and purchases by participants in certain group plans are not subject to an initial sales charge but may be subject to a contingent deferred sales charge of 1%. See "Buying, exchanging and selling shares." 2 Total annual fund operating expenses in the table have not been reduced by any expense offset arrangements. 3 Net expenses in the table reflect the expense limitations currently in effect, under which Pioneer has contractually agreed to limit ordinary operating expenses to the extent required to reduce fund expenses to 1.25% and 2.15% of the average daily net assets attributable to Class A and Class C shares, respectively. These expense limitations are in effect through May 1, 2009 for Class A shares and through May 1, 2008 for Class C shares. There can be no assurance that Pioneer will extend the expense limitations beyond such time. See the statement of additional information for details regarding the expense limitation agreement. 6 Non-principal investment strategies and related risks As discussed, the fund invests primarily in equity securities. The following sections describe additional investments that the fund may make or strategies that it may pursue to a lesser degree to achieve the fund's goal. The fund's secondary, or non-principal, investment policies and strategies also entail risks. To learn more about these investments and risks, you should obtain and read the statement of additional information (SAI). Initial public offerings To the extent consistent with its investment objective, the fund may invest in initial public offerings of equity securities. The market for such securities may be more volatile and entail greater risk of loss than investments in more established companies. Investments in initial public offerings represent a significant portion of the fund's past investment performance. The fund cannot assure that investments in initial public offerings will continue to be available to the fund or, if available, will continue to result in positive investment performance. In addition, as the fund grows in size, the impact of investments in initial public offerings on the overall performance of the fund's portfolio is likely to decrease. Investments in REITs The fund may invest up to 20% of its net assets in REITs. REITs are companies that invest primarily in real estate or real estate related loans. Investing in REITs involves unique risks. They are significantly affected by the market for real estate and are dependent upon management skills and cash flow. In addition to its own expenses, the fund will indirectly bear its proportionate share of any management and other expenses paid by REITs in which it invests. Debt securities The fund may invest up to 20% of its total assets in debt securities of corporate and government issuers. Generally the fund acquires debt securities that are investment grade, but the fund may invest up to 5% of its net assets in below investment grade debt securities, including below investment grade convertible debt securities. The fund invests in debt securities when Pioneer believes they are consistent with the fund's investment objective of capital growth, to diversify the fund's portfolio or for greater liquidity. Debt securities are subject to the risk of an issuer's inability to meet principal or interest payments on its obligations. Factors that could contribute to a decline in the market value of debt securities in the fund's portfolio include rising interest rates or a reduction in the perceived creditworthiness of the issuer of the securities. A debt security is investment grade if it is rated in one of the top four categories by a nationally recognized statistical rating organization or determined to be of equivalent credit quality by Pioneer. Debt securities rated below investment grade are commonly referred to as "junk bonds" and are considered speculative. Below investment grade 7 Basic information about the fund debt securities involve greater risk of loss, are subject to greater price volatility and are less liquid, especially during periods of economic uncertainty or change, than higher quality debt securities. Cash management and temporary investments Normally, the fund invests substantially all of its assets to meet its investment objective. The fund may invest the remainder of its assets in securities with remaining maturities of less than one year, cash equivalents or may hold cash. For temporary defensive purposes, including during periods of unusual cash flows, the fund may depart from its principal investment strategies and invest part or all of its assets in these securities or may hold cash. During such periods, the fund may not be able to achieve its investment objective. The fund intends to adopt a defensive strategy when Pioneer believes securities in which the fund normally invests have extraordinary risks due to political or economic factors and in other extraordinary circumstances. Short-term trading The fund usually does not trade for short-term profits. The fund will sell an investment, however, even if it has only been held for a short time, if it no longer meets the fund's investment criteria. If the fund does a lot of trading, it may incur additional operating expenses, which would reduce performance, and could cause shareowners to incur a higher level of taxable income or capital gains. See "Financial highlights" for actual annual turnover rates. Derivatives The fund may, but is not required to, use futures and options on securities, indices and currencies, forward foreign currency exchange contracts and other derivatives. A derivative is a security or instrument whose value is determined by reference to the value or the change in value of one or more securities, currencies, indices or other financial instruments. Although there is no specific limitation on investing in derivatives, the fund does not use derivatives as a primary investment technique and generally limits their use to hedging. However, the fund may use derivatives for a variety of non-principal purposes, including: o As a hedge against adverse changes in the market prices of securities, interest rates or currency exchange rates o As a substitute for purchasing or selling securities o To increase the fund's return as a non-hedging strategy that may be considered speculative 8 Even a small investment in derivatives can have a significant impact on the fund's exposure to the market prices of securities, interest rates or currency exchange rates. If changes in a derivative's value do not correspond to changes in the value of the fund's other investments, the fund may not fully benefit from or could lose money on the derivative position. In addition, some derivatives involve risk of loss if the person who issued the derivative defaults on its obligation. Certain derivatives may be less liquid and more difficult to value. The fund will only invest in derivatives to the extent Pioneer believes these investments do not prevent the fund from seeking its investment objective. 9 Management Pioneer, the fund's investment adviser, selects the fund's investments and oversees the fund's operations. Pioneer is an indirect, wholly owned subsidiary of UniCredito Italiano S.p.A., one of the largest banking groups in Italy. Pioneer is part of the global asset management group providing investment management and financial services to mutual funds, institutional and other clients. As of March 31, 2007, assets under management were approximately $310 billion worldwide, including over $81 billion in assets under management by Pioneer. Investment adviser Pioneer's main office is at 60 State Street, Boston, Massachusetts 02109. The firm's U.S. mutual fund investment history includes creating in 1928 one of the first mutual funds. Portfolio management Day-to-day management of the fund's portfolio is the responsibility of Andrew Acheson. Mr. Acheson is assisted by a team of analysts that meets to discuss holdings, prospective investments and portfolio composition. Members of this team manage other Pioneer funds investing primarily in U.S. equity securities. The portfolio manager and the team also may draw upon the research and investment management expertise of Pioneer's affiliate, Pioneer Investment Management Limited (PIML). Mr. Acheson, a vice president of Pioneer, joined Pioneer as a portfolio manager in May 2001 and has been an investment professional since 1994. The fund's statement of additional information provides additional information about the portfolio manager's compensation, other accounts managed by the portfolio manager, and the portfolio manager's ownership of shares of the fund. Management fee The fund pays Pioneer a fee for managing the fund and to cover the cost of providing certain services to the fund. Pioneer's annual fee is equal to 0.75% of the fund's average daily net assets. The fee is accrued daily and paid monthly. For the fiscal year ended December 31, 2006, the fund paid management fees equivalent to 0.75% of the fund's average daily net assets. A discussion regarding the basis for the Board of Trustees' approval of the management contract is available in the fund's annual report to shareholders, dated December 31, 2006. 10 Distributor and transfer agent Pioneer Funds Distributor, Inc. is the fund's distributor. Pioneer Investment Management Shareholder Services, Inc. is the fund's transfer agent. The fund compensates the distributor and transfer agent for their services. The distributor and the transfer agent are affiliates of Pioneer. Disclosure of portfolio holdings The fund's policies and procedures with respect to disclosure of the fund's portfolio securities are described in the statement of additional information 11 Buying, exchanging and selling shares Net asset value The fund's net asset value is the value of its portfolio of securities plus any other assets minus its operating expenses and any other liabilities. The fund calculates a net asset value for each class of shares every day the New York Stock Exchange is open when regular trading closes (normally 4:00 p.m. Eastern time). The fund generally values its portfolio securities using closing market prices or readily available market quotations. When closing market prices or market quotations are not available or are considered by Pioneer to be unreliable, the fund uses a security's fair value. All methods of determining the value of a security used by the fund, including those discussed below, on a basis other than market value, are forms of fair value. All valuations of securities on a fair value basis are made pursuant to procedures adopted by the Board of Trustees. The use of fair value pricing by the fund may cause the net asset value of its shares to differ from the net asset value that would be calculated only using market prices. For market prices and quotations, as well as for some fair value methods, the fund relies upon securities prices provided by pricing services. The fund uses the fair value of a security, including a non-U.S. security, when Pioneer determines that the closing market price on the primary exchange where the security is traded no longer accurately reflects the value of the security at the time the fund calculates its net asset value. This may occur for a variety of reasons that affect either the relevant securities markets generally or the specific issuer. For example, with respect to non-U.S. securities held by the fund, developments relating to specific events in the securities markets or the specific issuer may occur between the time the primary market closes and the time the fund determines its net asset value. In those circumstances when the fund believes the price of the security may be affected, the fund uses the fair value of the security. International securities markets may be open on days when the U.S. markets are closed. For this reason, the values of any international securities owned by the fund could change on a day you cannot buy or sell shares of the fund. Certain types of securities, including those discussed in this paragraph, are priced using fair value rather than market prices. The fund uses a pricing matrix to determine the value of fixed income securities that do not trade daily. A pricing matrix is a means of valuing a debt security on the basis of current market prices for other debt securities and historical trading patterns in the market for fixed income securities. The fund values cash equivalent securities with remaining maturities of 60 days or less at amortized cost. To the extent that the fund invests in the shares of other registered open-end investment companies that are not traded on an exchange (mutual funds), such shares are valued at their published net asset values per share as reported by the funds. The prospectuses of these funds explain the circumstances under which the funds will use fair value pricing and the effects of using fair value pricing. 12 You buy or sell shares at the share price. When you buy Class A shares, you pay an initial sales charge unless you qualify for a waiver or reduced sales charge. When you sell Class C shares, you may pay a contingent deferred sales charge depending on how long you have owned your shares. - -------------------------------------------------------------------------------- Share price The net asset value per share calculated on the day of your transaction, adjusted for any applicable sales charge. - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- Contingent deferred sales charge A sales charge that may be deducted from your sale proceeds. - -------------------------------------------------------------------------------- Choosing a class of shares The fund offers two classes of shares through this prospectus. Each class has different sales charges and expenses, allowing you to choose the class that best meets your needs. Factors you should consider include: o How long you expect to own the shares o The expenses paid by each class o Whether you qualify for any reduction or waiver of sales charges Your investment professional can help you determine which class meets your goals. Your investment firm may receive different compensation depending upon which class you choose. If you are not a U.S. citizen and are purchasing shares outside the U.S., you may pay different sales charges under local laws and business practices. Distribution plans The fund has adopted a distribution plan for each class of shares offered through this prospectus in accordance with Rule 12b-1 under the Investment Company Act of 1940. Under each plan, the fund pays distribution and service fees to the distributor. Because these fees are an ongoing expense of the fund, over time they increase the cost of your investment and your shares may cost more than shares that are subject to other types of sales charges. Additional payments to financial intermediaries There are two principal ways you compensate the financial intermediary through which you buy shares of the fund - directly, by the payment of sales commissions, if any; and indirectly, as a result of the fund paying Rule 12b-1 fees. 13 Buying, exchanging and selling shares Pioneer and its affiliates may make additional payments to your financial intermediary. These payments by Pioneer may provide your financial intermediary with an incentive to favor the Pioneer funds over other mutual funds or assist the distributor in its efforts to promote the sale of the fund's shares. Financial intermediaries include broker-dealers, banks (including bank trust departments), registered investment advisers, financial planners, retirement plan administrators and other types of intermediaries. Pioneer makes these additional payments (sometimes referred to as "revenue sharing") to financial intermediaries out of its own assets. Revenue sharing is not an expense of the Pioneer funds. Pioneer may base these payments on a variety of criteria, including the amount of sales or assets attributable to the financial intermediary or as a per transaction fee. Not all financial intermediaries receive additional compensation and the amount of compensation paid varies for each financial intermediary. In certain cases, these payments could be significant. Pioneer determines which firms to support and the extent of the payments it is willing to make, generally choosing firms that have a strong capability to effectively distribute shares of the Pioneer funds and that are willing to cooperate with Pioneer's promotional efforts. Pioneer also may compensate financial intermediaries for providing certain administrative services and transaction processing services. Pioneer may benefit from revenue sharing if the intermediary features the Pioneer funds in its sales system (such as by placing certain Pioneer funds on its preferred fund list or giving access on a preferential basis to members of the financial intermediary's sales force or management). In addition, the financial intermediary may agree to participate in the distributor's marketing efforts (such as by helping to facilitate or provide financial assistance for conferences, seminars or other programs at which Pioneer personnel may make presentations on the funds to the intermediary's sales force). To the extent intermediaries sell more shares of the Pioneer funds or retain shares of the Pioneer funds in their clients' accounts, Pioneer receives greater management and other fees due to the increase in the Pioneer funds' assets. Although an intermediary may request additional compensation from Pioneer to offset costs incurred by the financial intermediary in servicing its clients, the intermediary may earn a profit on these payments, if the amount of the payment may exceed the intermediary's costs. The compensation that Pioneer pays to financial intermediaries is discussed in more detail in the fund's statement of additional information. Your intermediary may charge you additional fees or commissions other than those disclosed in this prospectus. Intermediaries may categorize and disclose these arrangements differently than the discussion above and in the statement of additional information. You can ask your financial intermediary about any payments it 14 receives from Pioneer or the Pioneer funds, as well as about fees and/or commissions it charges. Pioneer and its affiliates may have other relationships with your financial intermediary relating to the provision of services to the funds, such as providing omnibus account services or effecting portfolio transactions for the Pioneer funds. If your intermediary provides these services, Pioneer or the Pioneer funds may compensate the intermediary for these services. In addition, your intermediary may have other relationships with Pioneer or its affiliates that are not related to the funds. 15 Buying, exchanging and selling shares Comparing classes of shares Class A Class C - --------------------------------------------------------------------------------------------------- Why you might Class A shares may be your best You may prefer Class C shares if you prefer each class alternative if you prefer to pay an do not wish to pay an initial sales initial sales charge and have lower charge and you would rather pay annual expenses, or if you qualify for higher annual expenses over time. any reduction or waiver of the initial sales charge. - --------------------------------------------------------------------------------------------------- Initial sales Up to 5.75% of the offering price, None. charge which is reduced or waived for large purchases and certain types of investors.

Since the offering price is calculated to two decimal places using standard rounding methodology, the dollar amount of the sales charge as a percentage of the offering price and of the net amount invested for any particular purchase of fund shares may be higher or lower due to rounding. Reduced sales charges You may qualify for a reduced Class A sales charge if you own or are purchasing shares of Pioneer mutual funds. The investment levels required to obtain a reduced sales charge are commonly referred to as "breakpoints." Pioneer offers two principal means of taking advantage of breakpoints in sales charges for aggregate purchases of Class A shares over time if: o The amount of shares you own plus the amount you are investing now is at least $50,000 (Rights of accumulation) o You plan to invest at least $50,000 over the next 13 months (Letter of intent) 17 Buying, exchanging and selling shares Rights of accumulation If you qualify for rights of accumulation, your sales charge will be based on the combined value (at the current offering price) of all your Pioneer mutual fund shares, the shares of your spouse and the shares of any children under the age of 21. Letter of intent You can use a letter of intent to qualify for reduced sales charges in two situations: o If you plan to invest at least $50,000 (excluding any reinvestment of dividends and capital gain distributions) in the fund's Class A shares during the next 13 months o If you include in your letter of intent the value (at the current offering price) of all of your Class A shares of the fund and Class A, Class B or Class C shares of all other Pioneer mutual fund shares held of record in the amount used to determine the applicable sales charge for the fund shares you plan to buy Completing a letter of intent does not obligate you to purchase additional shares, but if you do not buy enough shares to qualify for the projected level of sales charges by the end of the 13-month period (or when you sell your shares, if earlier), the distributor will recalculate your sales charge. You must pay the additional sales charge within 20 days after you are notified of the recalculation or it will be deducted from your account (or your sale proceeds). Any share class for which no sales charge is paid cannot be included under the letter of intent. For more information regarding letters of intent, please contact your investment professional or obtain and read the statement of additional information. 18 Qualifying for a reduced Class A sales charge In calculating your total account value in order to determine whether you have net sales charge breakpoints, you can include your Pioneer mutual fund shares, those of your spouse and the shares of any children under the age of 21. Pioneer will use each fund's current offering price to calculate your total account value. Certain trustees and fiduciaries may also qualify for a reduced sales charge. To receive a reduced sales charge, you or your investment professional must, at the time of purchase, notify the distributor of your eligibility. In order to verify your eligibility for a discount, you may need to provide your investment professional or the fund with information or records, such as account numbers or statements, regarding shares of the fund or other Pioneer mutual funds held in all accounts by you, your spouse or children under the age of 21 with that investment professional or with any other financial intermediary. Eligible accounts may include joint accounts, retirement plan accounts, such as IRA and 401k accounts, and custodial accounts, such as ESA, UGMA and UTMA accounts. It is your responsibility to confirm that your investment professional has notified the distributor of your eligibility for a reduced sales charge at the time of sale. If you or your investment professional do not notify the distributor of your eligibility, you will risk losing the benefits of a reduced sales charge. For this purpose, Pioneer mutual funds include any fund for which the distributor is principal underwriter and, at the distributor's discretion, may include funds organized outside the U.S. and managed by Pioneer or an affiliate.

The intermediaries sponsoring or participating in these mutual fund programs also may offer their clients other classes of shares of the funds and investors may receive different levels of services or pay different fees depending upon the class of shares included in the program. Investors should consider carefully any separate transaction and other fees charged by these programs in connection with investing in each available share class before selecting a share class. 21 Buying, exchanging and selling shares Reinstatement privilege for Class A shares If you recently sold all or part of your Class A shares, you may be able to reinvest all or part of your sale proceeds without a sales charge in Class A shares of any Pioneer mutual fund.

A contingent deferred sales charge is payable to the distributor in the event of a share redemption within 18 months following the share purchase at the rate of 1% of the lesser of the value of the shares redeemed (exclusive of reinvested dividend and capital gain distributions) or the total cost of such shares. However, the contingent deferred sales charge is waived for redemptions of Class A shares purchased by an employer-sponsored retirement plan described under Section 401(a), 403(b) or 457 of the Internal Revenue Code that has at least $1 million in total plan assets (or that has 1,000 or more eligible employees for plans with accounts established with Pioneer on or before March 31, 2004). - -------------------------------------------------------------------------------- Contingent deferred sales charge A sales charge that may be deducted from your sale proceeds. - -------------------------------------------------------------------------------- 22 Sales charges: Class C shares You buy Class C shares at net asset value per share without paying an initial sales charge.

See "Waiver or reduction of contingent deferred sales charges" - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- Contingent deferred sales charge A sales charge that may be deducted from your sale proceeds. - -------------------------------------------------------------------------------- Waiver or reduction of contingent deferred sales charges (CDSC) It is your responsibility to confirm that your investment professional has notified the distributor of your eligibility for a reduced sales charge at the time of sale. If you or your investment professional do not notify the distributor of your eligibility, you will risk losing the benefits of a reduced sales charge. Class A and Class C shares The distributor may waive or reduce the CDSC for Class A shares that are subject to a CDSC or for Class C shares if: o The distribution results from the death of all registered account owners or a participant in an employer-sponsored plan. For UGMAs, UTMAs and trust accounts, the waiver applies only upon the death of all beneficial owners; o You become disabled (within the meaning of Section 72 of the Internal Revenue Code) after the purchase of the shares being sold. For UGMAs, UTMAs and trust accounts, the waiver only applies upon the disability of all beneficial owners; o The distribution is made in connection with limited automatic redemptions as described in "Systematic withdrawal plans" (limited in any year to 10% of the value of the account in the fund at the time the withdrawal plan is established); 23 Buying, exchanging and selling shares o The distribution is from any type of IRA, 403(b) or employer-sponsored plan described under Section 401(a) or 457 of the Internal Revenue Code and, in connection with the distribution, one of the following applies: - It is part of a series of substantially equal periodic payments made over the life expectancy of the participant or the joint life expectancy of the participant and his or her beneficiary (limited in any year to 10% of the value of the participant's account at the time the distribution amount is established); - It is a required minimum distribution due to the attainment of age 70-1/2, in which case the distribution amount may exceed 10% (based solely on total plan assets held in Pioneer mutual funds); - It is rolled over to or reinvested in another Pioneer mutual fund in the same class of shares, which will be subject to the CDSC of the shares originally held; or - It is in the form of a loan to a participant in a plan that permits loans (each repayment applied to the purchase of shares will be subject to a CDSC as though a new purchase); o The distribution is to a participant in an employer-sponsored retirement plan described under Section 401(a) of the Internal Revenue Code or to a participant in an employer-sponsored 403(b) plan or employer-sponsored 457 plan if (i) your employer has made special arrangements for your plan to operate as a group through a single broker, dealer or financial intermediary and (ii) all participants in the plan who purchase shares of a Pioneer mutual fund do so through a single broker, dealer or other financial intermediary designated by your employer and is or is in connection with: - A return of excess employee deferrals or contributions; - A qualifying hardship distribution as described in the Internal Revenue Code.

If the fund accepts your securities, they will be valued for purposes of determining the number of fund shares to be issued to you in the same way the fund will value the securities for purposes of determining its net asset value. For federal income tax purposes, you may be taxed in the same manner as if you sold the securities that you exchange for cash in an amount equal to the value of the fund shares that you receive in exchange. Your sales charge for purchases of fund shares will be based upon the value of the fund shares that you receive. Your broker may also impose a fee in connection with processing your purchase of fund shares with securities. Minimum investment amounts Your initial investment must be at least $1,000. Additional investments must be at least $100 for Class A shares and $500 for Class C shares. You may qualify for lower initial or subsequent investment minimums if you are opening a retirement plan account, establishing an automatic investment plan or placing your trade through your investment firm. The fund may waive the initial or subsequent investment minimums. Minimum investment amounts may be waived for share purchases made through certain mutual fund programs (e.g., asset based fee program accounts) sponsored by qualified intermediaries, such as broker-dealers and investment advisers, that have entered into an agreement with Pioneer. Maximum purchase amounts Purchases of fund shares are limited to $999,999 for Class C shares. This limit is applied on a per transaction basis. Class A shares are not subject to a maximum purchase amount. - -------------------------------------------------------------------------------- Retirement plan accounts You can purchase fund shares through tax-deferred retirement plans for individuals, businesses and tax-exempt organizations.

When you open an account, you will need to supply your name, address, date of birth, and other information that will allow the fund to identify you. The fund may close your account if we cannot adequately verify your identity. The redemption price will be the net asset value (less applicable sales charges) on the date of redemption. Exchanging You may exchange your shares for shares of the same class of another Pioneer mutual fund. Your exchange request must be for at least $1,000. The fund allows you to exchange your shares at net asset value without charging you either an initial or contingent deferred sales charge at the time of the exchange. Shares you acquire as part of an exchange will continue to be subject to any contingent deferred sales charge that applies to the shares you originally purchased. When you ultimately sell your shares, the date of your original purchase will determine your contingent deferred sales charge. Your exchanges are subject to certain limitations. See "Shareowner Account Policies - Exchange Limitation." Before you request an exchange, consider each fund's investment objective and policies as described in the fund's prospectus. Selling Your shares will be sold at net asset value per share next calculated after the fund or its authorized agent, such as broker-dealers, receives your request in good order.

If you recently sent a check to purchase the shares being sold, the fund may delay payment of the sale proceeds until your check has cleared. This may take up to 15 calendar days from the purchase date. If you are selling shares from a non-retirement account or certain IRAs, you may use any of the methods described below. If you are selling shares from a retirement account other than an IRA, you must make your request in writing. - -------------------------------------------------------------------------------- You may have to pay income taxes on a sale or an exchange. - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- Consult your investment professional to learn more about buying, exchanging or selling fund shares. - -------------------------------------------------------------------------------- 29 Buying, exchanging and selling shares Buying shares Through your investment firm Normally, your investment firm will send your purchase request to the fund's distributor and/or transfer agent.

An investor may use short-term trading as a strategy, for example, if the investor believes that the valuation of the fund's portfolio securities for purposes of calculating its net asset value does not fully reflect the then current fair market value of those holdings. The fund discourages, and does not take any intentional action to accommodate, excessive and short-term trading practices, such as market timing. Although there is no generally applied standard in the marketplace as to what level of trading activity is excessive, we may consider trading in the fund's shares to be excessive for a variety of reasons, such as if: o You sell shares within a short period of time after the shares were purchased; o You make two or more purchases and redemptions within a short period of time; o You enter into a series of transactions that is indicative of a timing pattern or strategy; or o We reasonably believe that you have engaged in such practices in connection with other mutual funds. The fund's Board of Trustees has adopted policies and procedures with respect to frequent purchases and redemptions of fund shares by fund investors. Pursuant to these policies and procedures, we monitor selected trades on a daily basis in an effort to detect excessive short-term trading. If we determine that an investor or a client of a broker has engaged in excessive short-term trading that we believe may be harmful to the fund, we will ask the investor or broker to cease such activity and we will refuse to process purchase orders (including purchases by exchange) of such investor, broker or accounts that we believe are under their control. In determining whether to take such actions, we seek to act in a manner that is consistent with the best interests of the fund's shareholders. While we use our reasonable efforts to detect excessive trading activity, there can be no assurance that our efforts will be successful or that market timers will not employ tactics designed to evade detection. If we are not successful, your return from an investment in the fund may be adversely affected. Frequently, fund shares are held through omnibus accounts maintained by financial intermediaries such as brokers and retirement plan administrators, where the holdings of multiple shareholders, such as all the clients of a particular broker, are aggregated. Our ability to monitor trading practices by investors purchasing shares through omnibus accounts is limited and dependent upon the cooperation of the financial intermediary in taking steps to limit this type of activity. 34 In addition to monitoring trades, the policies and procedures provide that: o The fund imposes limitations on the number of exchanges out of an account holding the fund's Class A, Class C or Class P shares that may occur in any calendar year. See "Exchange limitation." The fund may reject a purchase or exchange order before its acceptance or an order prior to issuance of shares. The fund may also restrict additional purchases or exchanges in an account. Each of these steps may be taken, for any reason, without prior notice, including transactions that the fund believes are requested on behalf of market timers. The fund reserves the right to reject any purchase request by any investor or financial institution if the fund believes that any combination of trading activity in the account or related accounts is potentially disruptive to the fund. A prospective investor whose purchase or exchange order is rejected will not achieve the investment results, whether gain or loss, that would have been realized if the order were accepted and an investment made in the fund. The fund and its shareholders do not incur any gain or loss as a result of a rejected order. The fund may impose further restrictions on trading activities by market timers in the future. The fund's prospectus will be amended or supplemented to reflect any material additional restrictions on trading activities intended to prevent excessive trading. Account options See the account application form for more details on each of the following options. Automatic investment plans You can make regular periodic investments in the fund by setting up monthly bank drafts, government allotments, payroll deductions, a Pioneer Investomatic Plan and other similar automatic investment plans. You may use an automatic investment plan to establish a Class A share account with a small initial investment. If you have a Class C share account and your balance is at least $1,000, you may establish an automatic investment plan. Pioneer Investomatic Plan If you establish a Pioneer Investomatic Plan, the transfer agent will make a periodic investment in fund shares by means of a preauthorized electronic funds transfer from your bank account. Your plan investments are voluntary. You may discontinue your plan at any time or change the plan's dollar amount, frequency or investment date by calling or writing to the transfer agent. You should allow up to 30 days for the transfer agent to establish your plan. Automatic exchanges You can automatically exchange your fund shares for shares of the same class of another Pioneer mutual fund. The automatic exchange will begin on the day you 35 Buying, exchanging and selling shares select when you complete the appropriate section of your account application or an account options form. In order to establish automatic exchange: o You must select exchanges on a monthly or quarterly basis o Both the originating and receiving accounts must have identical registrations o The originating account must have a minimum balance of $5,000 You may have to pay income taxes on an exchange. Distribution options The fund offers three distribution options. Any fund shares you buy by reinvesting distributions will be priced at the applicable net asset value per share. (1) Unless you indicate another option on your account application, any dividends and capital gain distributions paid to you by the fund will automatically be invested in additional fund shares. (2) You may elect to have the amount of any dividends paid to you in cash and any capital gain distributions reinvested in additional shares. (3) You may elect to have the full amount of any dividends and/or capital gain distributions paid to you in cash. Options (2) or (3) are not available to retirement plan accounts or accounts with a current value of less than $500. If your distribution check is returned to the transfer agent or you do not cash the check for six months or more, the transfer agent may reinvest the amount of the check in your account and automatically change the distribution option on your account to option (1) until you request a different option in writing. If the amount of a distribution check would be less than $10, the fund may reinvest the amount instead of sending a check. Additional shares will be purchased at the then current net asset value. Directed dividends You can invest the dividends paid by one of your Pioneer mutual fund accounts in a second Pioneer mutual fund account. The value of your second account must be at least $1,000. You may direct the investment of any amount of dividends. There are no fees or charges for directed dividends. If you have a retirement plan account, you may only direct dividends to accounts with identical registrations. Systematic withdrawal plans When you establish a systematic withdrawal plan for your account, the transfer agent will sell the number of fund shares you specify on a periodic basis and the proceeds will be paid to you or to any person you select. You must obtain a signature guarantee to direct payments to another person after you have established your systematic withdrawal plan. Payments can be made either by check or by electronic transfer to a bank account you designate. 36 To establish a systematic withdrawal plan: o Your account must have a total value of at least $10,000 when you establish your plan o You must request a periodic withdrawal of at least $50 o You may not request a periodic withdrawal of more than 10% of the value of any Class C share account (valued at the time the plan is implemented) These requirements do not apply to scheduled (Internal Revenue Code Section 72(t) election) or mandatory (required minimum distribution) withdrawals from IRAs and certain retirement plans. Systematic sales of fund shares may be taxable transactions for you. While you are making systematic withdrawals from your account, you may pay unnecessary initial sales charges on additional purchases of Class A shares or contingent deferred sales charges. Direct deposit If you elect to take dividends or dividends and capital gain distributions in cash, or if you establish a systematic withdrawal plan, you may choose to have those cash payments deposited directly into your savings, checking or NOW bank account. Voluntary tax withholding You may have the transfer agent withhold 28% of the dividends and capital gain distributions paid from your fund account (before any reinvestment) and forward the amount withheld to the Internal Revenue Service as a credit against your federal income taxes.

You cannot obtain a signature guarantee from a notary public. The Pioneer funds generally accept only medallion signature guarantees. A medallion signature guarantee may be obtained from a domestic bank or trust company, broker, dealer, clearing agency, savings association, or other financial institution that is participating in a medallion program recognized by the Securities Transfer Association. Signature guarantees from financial institutions that are not participating in one of these programs are not accepted as medallion signature guarantees. The fund may accept other forms of guarantee from financial intermediaries in limited circumstances. Fiduciaries and corporations are required to submit additional documents to sell fund shares. Exchange limitation You may only make up to four exchange redemptions of $25,000 or more per account per calendar year out of the fund. The fund's exchange limitation is intended to discourage short-term trading in fund shares. Short-term trading can increase the expenses incurred by the fund and make portfolio management less efficient. In determining whether the exchange redemption limit has been reached, Pioneer may aggregate a series of exchanges (each valued at less than $25,000) and/or fund accounts that appear to be under common ownership or control. Pioneer may view accounts for which one person gives instructions or accounts that act on advice provided by a single source to be under common control. The exchange limitation does not apply to automatic exchange transactions or to exchanges made by participants in employer-sponsored retirement plans qualified under Section 401(a) of the Internal Revenue Code. While financial intermediaries that maintain omnibus accounts that invest in the fund are requested to apply the exchange limitation policy to shareholders who hold shares through such accounts, we do not impose the exchange limitation policy at the level of the omnibus account and are not able to monitor compliance by the financial intermediary with this policy. 39 Buying, exchanging and selling shares Minimum account size The fund requires that you maintain a minimum account value of $500. If you hold less than $500 in your account, the fund reserves the right to notify you that it intends to sell your shares and close your account. You will be given 60 days from the date of the notice to make additional investments to avoid having your shares sold. This policy does not apply to certain qualified retirement plan accounts. Telephone and website access You may have difficulty contacting the fund by telephone or accessing pioneerinvestments.com during times of market volatility or disruption in telephone or Internet service. On New York Stock Exchange holidays or on days when the exchange closes early, Pioneer will adjust the hours for the telephone center and for online transaction processing accordingly. If you are unable to access pioneerinvestments.com or reach the fund by telephone, you should communicate with the fund in writing. Share certificates The fund does not offer share certificates. Shares are electronically recorded. Any existing certificated shares can only be sold by returning your certificate to the transfer agent, along with a letter of instruction or a stock power (a separate written authority transferring ownership) and a signature guarantee. Other policies The fund and the distributor reserve the right to: o reject any purchase or exchange order for any reason, without prior notice o charge a fee for exchanges or to modify, limit or suspend the exchange privilege at any time without notice. The fund will provide 60 days' notice of material amendments to or termination of the exchange privilege o revise, suspend, limit or terminate the account options or services available to shareowners at any time, except as required by the rules of the Securities and Exchange Commission The fund reserves the right to: o suspend transactions in shares when trading on the New York Stock Exchange is closed or restricted, when the Securities and Exchange Commission determines an emergency or other circumstances exist that make it impracticable for the fund to sell or value its portfolio securities o redeem in kind by delivering to you portfolio securities owned by the fund rather than cash. Securities you receive this way may increase or decrease in value while you hold them and you may incur brokerage and transaction charges and tax liability when you convert the securities to cash o charge transfer, shareholder servicing or similar agent fees, such as an account maintenance fee for small balance accounts, directly to accounts upon at least 30 days' notice. The fund may do this by deducting the fee from your distribution of dividends and/or by redeeming shares to the extent necessary to cover the fee 40 Dividends, capital gains and taxes Dividends and capital gains The fund generally pays any distributions of net short- and long-term capital gains in November. The fund generally pays dividends from any net investment income in December. The fund may also pay dividends and capital gain distributions at other times if necessary for the fund to avoid U.S. federal income or excise tax. If you invest in the fund close to the time that the fund makes a distribution, generally you will pay a higher price per share and you will pay taxes on the amount of the distribution whether you reinvest the distribution or receive it as cash. Taxes For U.S. federal income tax purposes, distributions from the fund's net long-term capital gains (if any) are considered long-term capital gains and may be taxable to you at different maximum rates depending upon their source and other factors. Distributions from the fund's net short-term capital gains are taxable as ordinary income. Dividends are taxable either as ordinary income or, if so designated by the fund and certain other conditions, including holding period requirements, are met by the fund and the shareholder, as "qualified dividend income" taxable to individual shareholders at a maximum 15% U.S. federal income tax rate. Dividends and distributions are taxable, whether you take payment in cash or reinvest them to buy additional fund shares. When you sell or exchange fund shares you will generally recognize a capital gain or capital loss in an amount equal to the difference between the net amount of sale proceeds (or, in the case of an exchange, the fair market value of the shares) that you receive and your tax basis for the shares that you sell or exchange. In January of each year the fund will mail to you information about your dividends, distributions and any shares you sold in the previous calendar year. You must provide your social security number or other taxpayer identification number to the fund along with the certifications required by the Internal Revenue Service when you open an account. If you do not or if it is otherwise legally required to do so, the fund will withhold 28% "backup withholding" tax from your dividends and distributions, sale proceeds and any other payments to you. You should ask your tax adviser about any federal, state, local and foreign tax considerations, including possible additional withholding taxes for non-U.S. shareholders. You may also consult the fund's statement of additional information for a more detailed discussion of qualified dividend income and other U.S. federal income tax considerations that may affect the fund and its shareowners. - -------------------------------------------------------------------------------- Sales and exchanges may be taxable transactions to shareowners. - -------------------------------------------------------------------------------- 41 Financial highlights The financial highlights table helps you understand the fund's financial performance since the inception of Class A and Class C shares.

Principal investment strategies The fund invests at least 80% of its assets in equity securities. For purposes of the fund's investment policies, equity securities include common stocks, convertible debt and other equity instruments, such as exchange-traded funds (ETFs) that invest primarily in equity securities, depositary receipts, warrants, rights, equity interests in real estate investment trusts (REITs) and preferred stocks. The fund may invest up to 25% of its total assets in equity and debt securities of non-U.S. corporate issuers and debt securities of non-U.S. government issuers, including up to 10% of its assets in the securities of emerging markets issuers. The fund invests in non-U.S. securities to diversify its portfolio when they offer similar or greater potential for capital appreciation compared to U.S. securities. Pioneer Investment Management, Inc., the fund's investment adviser, seeks securities selling at reasonable prices or substantial discounts to their underlying values and then holds these securities until the market values reflect their intrinsic values. Pioneer evaluates a security's potential value, including the attractiveness of its market valuation, based on the company's assets and prospects for earnings and revenue growth. In making that assessment, Pioneer employs due diligence and fundamental research, an evaluation of the issuer based on its financial statements and operations. Pioneer relies on the knowledge, experience and judgment of its staff and the staff of its affiliates who have access to a wide variety of research. Pioneer focuses on the quality and price of individual issuers, not on economic sector or market-timing strategies. Factors Pioneer looks for in selecting investments include: o Estimated private market value in excess of current stock price. Private market value is the price an independent investor would pay to own the entire company o Above average potential for earnings and revenue growth o Management with demonstrated ability and commitment to the company o Low market valuations relative to earnings forecast, book value, cash flow and sales Principal risks of investing in the fund You could lose money on your investment or not make as much as if you invested elsewhere if: o The stock market goes down or performs poorly relative to other investments (this risk may be greater in the short term) o Value stocks fall out of favor with investors o The fund's investments do not have the growth potential originally expected Risks of non-U.S. investments Investing in non-U.S. issuers may involve unique risks compared to investing in securities of U.S. issuers. These risks are more pronounced for issuers in 1 Basic information about the fund emerging markets or to the extent that the fund invests significantly in one region or country. These risks may include: o Less information about non-U.S. issuers or markets may be available due to less rigorous disclosure or accounting standards or regulatory practices o Many non-U.S. markets are smaller, less liquid and more volatile. In a changing market, Pioneer may not be able to sell the fund's portfolio securities at times, in amounts and at prices it considers reasonable o Adverse effect of currency exchange rates or controls on the value of the fund's investments o The economies of non-U.S. countries may grow at slower rates than expected or may experience a downturn or recession o Economic, political and social developments may adversely affect the securities markets o Withholding and other non-U.S. taxes may decrease the fund's return Market segment risks To the extent the fund emphasizes, from time to time, investments in a market segment, the fund will be subject to a greater degree to the risks particular to the industries in that segment, and may experience greater market fluctuation, than a fund without the same focus. For example, industries in the financial segment, such as banks, insurance companies, broker-dealers and real estate investment trusts (REITs), may be sensitive to changes in interest rates and general economic activity and are subject to extensive government regulation. Industries in the technology segment, such as information technology, communications equipment, computer hardware and software, and office and scientific equipment, are subject to risks of rapidly evolving technology, short product lives, rates of corporate expenditures, falling prices and profits, competition from new market entrants, and general economic conditions. 2 The fund's past performance The bar chart and table indicate the risks of investing in the fund by showing how the fund has performed in the past. The fund's performance will vary from year to year. The fund's past performance does not necessarily indicate how it will perform in the future. As a shareowner, you may lose or make money on your investment. Fund performance The chart shows the year-by-year performance of the fund's Class Y shares. The performance of Class Y shares for the period prior to the commencement of operations of Class Y shares is the net asset value performance of the fund's Class P shares, which has not been restated to reflect any differences in expenses, including Rule 12b-1 fees applicable to Class P shares. The chart does not reflect any sales charge you may pay when you buy or sell fund shares. Any sales charge will reduce your return. You do not pay a sales charge on purchases or redemptions of Class Y shares.

The Russell 1000 Index measures the performance of large-cap U.S. stocks. The Russell 1000 Growth Index measures the performance of large-cap U.S. growth stocks. The fund's benchmark has changed from the Russell 1000 Index to the Russell 1000 Growth Index. It is Pioneer's opinion that since the Russell 1000 Growth Index better reflects the fund's investment strategies, it is a more appropriate benchmark for the fund. Unlike the fund, the indices are not managed and do not incur expenses. The table: o Assumes that you sell your shares at the end of the period o Assumes that you reinvest all of your dividends and distributions The performance of Class Y shares for the period prior to the commencement of operations of Class Y shares is the net asset value performance of the fund's Class P shares, which has not been restated to reflect any differences in expenses, including Rule 12b-1 fees applicable to Class P shares.

The following sections describe additional investments that the fund may make or strategies that it may pursue to a lesser degree to achieve the fund's goal. The fund's secondary, or non-principal, investment policies and strategies also entail risks. To learn more about these investments and risks, you should obtain and read the statement of additional information (SAI). Initial public offerings To the extent consistent with its investment objective, the fund may invest in initial public offerings of equity securities. The market for such securities may be more volatile and entail greater risk of loss than investments in more established companies. Investments in initial public offerings represent a significant portion of the fund's past investment performance. The fund cannot assure that investments in initial public offerings will continue to be available to the fund or, if available, will continue to result in positive investment performance. In addition, as the fund grows in size, the impact of investments in initial public offerings on the overall performance of the fund's portfolio is likely to decrease. Investments in REITs The fund may invest up to 20% of its net assets in REITs. REITs are companies that invest primarily in real estate or real estate related loans. Investing in REITs involves unique risks. They are significantly affected by the market for real estate and are dependent upon management skills and cash flow. In addition to its own expenses, the fund will indirectly bear its proportionate share of any management and other expenses paid by REITs in which it invests. Debt securities The fund may invest up to 20% of its total assets in debt securities of corporate and government issuers. Generally the fund acquires debt securities that are investment grade, but the fund may invest up to 5% of its net assets in below investment grade debt securities, including below investment grade convertible debt securities. The fund invests in debt securities when Pioneer believes they are consistent with the fund's investment objective of capital growth, to diversify the fund's portfolio or for greater liquidity. Debt securities are subject to the risk of an issuer's inability to meet principal or interest payments on its obligations. Factors that could contribute to a decline in the market value of debt securities in the fund's portfolio include rising interest rates or a reduction in the perceived creditworthiness of the issuer of the securities. A debt security is investment grade if it is rated in one of the top four categories by a nationally recognized statistical rating organization or determined to be of equivalent credit quality by Pioneer. Debt securities rated below 6 investment grade are commonly referred to as "junk bonds" and are considered speculative. Below investment grade debt securities involve greater risk of loss, are subject to greater price volatility and are less liquid, especially during periods of economic uncertainty or change, than higher quality debt securities. Cash management and temporary investments Normally, the fund invests substantially all of its assets to meet its investment objective. The fund may invest the remainder of its assets in securities with remaining maturities of less than one year, cash equivalents or may hold cash. For temporary defensive purposes, including during periods of unusual cash flows, the fund may depart from its principal investment strategies and invest part or all of its assets in these securities or may hold cash. During such periods, the fund may not be able to achieve its investment objective. The fund intends to adopt a defensive strategy when Pioneer believes securities in which the fund normally invests have extraordinary risks due to political or economic factors and in other extraordinary circumstances. Short-term trading The fund usually does not trade for short-term profits. The fund will sell an investment, however, even if it has only been held for a short time, if it no longer meets the fund's investment criteria. If the fund does a lot of trading, it may incur additional operating expenses, which would reduce performance, and could cause shareowners to incur a higher level of taxable income or capital gains. See "Financial highlights" for actual annual turnover rates. Derivatives The fund may, but is not required to, use futures and options on securities, indices and currencies, forward foreign currency exchange contracts and other derivatives. A derivative is a security or instrument whose value is determined by reference to the value or the change in value of one or more securities, currencies, indices or other financial instruments. Although there is no specific limitation on investing in derivatives, the fund does not use derivatives as a primary investment technique and generally limits their use to hedging. However, the fund may use derivatives for a variety of non-principal purposes, including: o As a hedge against adverse changes in the market prices of securities, interest rates or currency exchange rates o As a substitute for purchasing or selling securities o To increase the fund's return as a non-hedging strategy that may be considered speculative Even a small investment in derivatives can have a significant impact on the fund's exposure to the market prices of securities, interest rates or currency exchange rates. If changes in a derivative's value do not correspond to changes in the value of the fund's other investments, the fund may not fully benefit from or could lose money on the derivative position. In addition, some derivatives involve risk of loss 7 Basic information about the fund if the person who issued the derivative defaults on its obligation. Certain derivatives may be less liquid and more difficult to value. The fund will only invest in derivatives to the extent Pioneer believes these investments do not prevent the fund from seeking its investment objective. 8 Management Pioneer, the fund's investment adviser, selects the fund's investments and oversees the fund's operations. Pioneer is an indirect, wholly owned subsidiary of UniCredito Italiano S.p.A., one of the largest banking groups in Italy. Pioneer is part of the global asset management group providing investment management and financial services to mutual funds, institutional and other clients. As of March 31, 2007, assets under management were approximately $310 billion worldwide, including over $81 billion in assets under management by Pioneer. Investment adviser Pioneer's main office is at 60 State Street, Boston, Massachusetts 02109. The firm's U.S. mutual fund investment history includes creating in 1928 one of the first mutual funds. Portfolio management Day-to-day management of the fund's portfolio is the responsibility of Andrew Acheson. Mr. Acheson is assisted by a team of analysts that meets to discuss holdings, prospective investments and portfolio composition. Members of this team manage other Pioneer funds investing primarily in U.S. equity securities. The portfolio manager and the team also may draw upon the research and investment management expertise of Pioneer's affiliate, Pioneer Investment Management Limited (PIML). Mr. Acheson, a vice president of Pioneer, joined Pioneer as a portfolio manager in May 2001 and has been an investment professional since 1994. The fund's statement of additional information provides additional information about the portfolio manager's compensation, other accounts managed by the portfolio manager, and the portfolio manager's ownership of shares of the fund. Management fee The fund pays Pioneer a fee for managing the fund and to cover the cost of providing certain services to the fund. Pioneer's annual fee is equal to 0.75% of the fund's average daily net assets. The fee is accrued daily and paid monthly. For the fiscal year ended December 31, 2006, the fund paid management fees equivalent to 0.75% of the fund's average daily net assets. A discussion regarding the basis for the Board of Trustees' approval of the management contract is available in the fund's annual report to shareholders, dated December 31, 2006. 9 Management Distributor and transfer agent Pioneer Funds Distributor, Inc. is the fund's distributor. Pioneer Investment Management Shareholder Services, Inc. is the fund's transfer agent. The fund compensates the distributor and transfer agent for their services. The distributor and the transfer agent are affiliates of Pioneer. Disclosure of portfolio holdings The fund's policies and procedures with respect to disclosure of the fund's portfolio securities are described in the statement of additional information. 10 Buying, exchanging and selling shares Net asset value The fund's net asset value is the value of its portfolio of securities plus any other assets minus its operating expenses and any other liabilities. The fund calculates a net asset value for each class of shares every day the New York Stock Exchange is open when regular trading closes (normally 4:00 p.m. Eastern time). The fund generally values its portfolio securities using closing market prices or readily available market quotations. When closing market prices or market quotations are not available or are considered by Pioneer to be unreliable, the fund uses a security's fair value. All methods of determining the value of a security used by the fund, including those discussed below, on a basis other than market value, are forms of fair value. All valuations of securities on a fair value basis are made pursuant to procedures adopted by the Board of Trustees. The use of fair value pricing by the fund may cause the net asset value of its shares to differ from the net asset value that would be calculated only using market prices. For market prices and quotations, as well as for some fair value methods, the fund relies upon securities prices provided by pricing services. The fund uses the fair value of a security, including a non-U.S. security, when Pioneer determines that the closing market price on the primary exchange where the security is traded no longer accurately reflects the value of the security at the time the fund calculates its net asset value. This may occur for a variety of reasons that affect either the relevant securities markets generally or the specific issuer. For example, with respect to non-U.S. securities held by the fund, developments relating to specific events in the securities markets or the specific issuer may occur between the time the primary market closes and the time the fund determines its net asset value. In those circumstances when the fund believes the price of the security may be affected, the fund uses the fair value of the security. International securities markets may be open on days when the U.S. markets are closed. For this reason, the values of any international securities owned by the fund could change on a day you cannot buy or sell shares of the fund. Certain types of securities, including those discussed in this paragraph, are priced using fair value rather than market prices. The fund uses a pricing matrix to determine the value of fixed income securities that do not trade daily. A pricing matrix is a means of valuing a debt security on the basis of current market prices for other debt securities and historical trading patterns in the market for fixed income securities. The fund values cash equivalent securities with remaining maturities of 60 days or less at amortized cost. To the extent that the fund invests in the shares of other registered open-end investment companies that are not traded on an exchange (mutual funds), such shares are valued at their published net asset values per share as reported by the funds. The prospectuses of these funds explain the circumstances under which the funds will use fair value pricing and the effects of using fair value pricing. 11 Buying, exchanging and selling shares You buy or sell Class Y shares at the share price. - -------------------------------------------------------------------------------- Share price The net asset value per share calculated on the day of your transaction. - -------------------------------------------------------------------------------- Distribution of Class Y shares The distributor incurs the expenses of distributing the fund's Class Y shares, none of which are reimbursed by the fund or the Class Y shareowners. Distribution expenses include fees paid to broker-dealers which have sales agreements with the distributor and other parties, advertising expenses and the cost of printing and mailing prospectuses to potential investors. Additional payments to financial intermediaries Pioneer and its affiliates may make additional payments to your financial intermediary. These payments by Pioneer may provide your financial intermediary with an incentive to favor the Pioneer funds over other mutual funds or assist the distributor in its efforts to promote the sale of the fund's shares. Financial intermediaries include broker-dealers, banks (including bank trust departments), registered investment advisers, financial planners, retirement plan administrators and other types of intermediaries. Pioneer makes these additional payments (sometimes referred to as "revenue sharing") to financial intermediaries out of its own assets. Revenue sharing is not an expense of the Pioneer funds. Pioneer may base these payments on a variety of criteria, including the amount of sales or assets attributable to the financial intermediary or as a per transaction fee. Not all financial intermediaries receive additional compensation and the amount of compensation paid varies for each financial intermediary. In certain cases, these payments could be significant. Pioneer determines which firms to support and the extent of the payments it is willing to make, generally choosing firms that have a strong capability to effectively distribute shares of the Pioneer funds and that are willing to cooperate with Pioneer's promotional efforts. Pioneer also may compensate financial intermediaries for providing certain administrative services and transaction processing services. Pioneer may benefit from revenue sharing if the intermediary features the Pioneer funds in its sales system (such as by placing certain Pioneer funds on its preferred fund list or giving access on a preferential basis to members of the financial intermediary's sales force or management). In addition, the financial intermediary may agree to participate in the distributor's marketing efforts (such as by helping to facilitate or provide financial assistance for conferences, seminars or other programs at which Pioneer personnel may make presentations on the funds to the intermediary's sales force). To the extent intermediaries sell more shares of the 12 Pioneer funds or retain shares of the Pioneer funds in their clients' accounts, Pioneer receives greater management and other fees due to the increase in the Pioneer funds' assets. Although an intermediary may request additional compensation from Pioneer to offset costs incurred by the financial intermediary in servicing its clients, the intermediary may earn a profit on these payments, if the amount of the payment may exceed the intermediary's costs. The compensation that Pioneer pays to financial intermediaries is discussed in more detail in the fund's statement of additional information. Your intermediary may charge you additional fees or commissions other than those disclosed in this prospectus. Intermediaries may categorize and disclose these arrangements differently than the discussion above and in the statement of additional information. You can ask your financial intermediary about any payments it receives from Pioneer or the Pioneer funds, as well as about fees and/or commissions it charges. Pioneer and its affiliates may have other relationships with your financial intermediary relating to the provision of services to the funds, such as providing omnibus account services or effecting portfolio transactions for the Pioneer funds. If your intermediary provides these services, Pioneer or the Pioneer funds may compensate the intermediary for these services. In addition, your intermediary may have other relationships with Pioneer or its affiliates that are not related to the funds. 13 Buying, exchanging and selling shares Opening your account If you are an individual or other non-institutional investor, open your Class Y share account by completing an account application and sending it to the transfer agent by mail or by fax. If you are any other type of investor, please call the transfer agent to obtain a Class Y share account application and an account number. If you invest in the fund through investment professionals or other financial intermediaries, including wrap programs and fund supermarkets, additional conditions may apply to your investment in the fund, and the investment professional or intermediary may charge you a transaction-based or other fee for its services. These conditions and fees are in addition to those imposed by the fund and its affiliates. You should ask your investment professional or financial intermediary about its services and any applicable fees. The transfer agent must receive your account application before you send your initial check or federal funds wire. In addition, you must provide a bank wire address of record when you establish your account. If your shares are held in your investment firm's name, the options and services available to you may be different from those discussed in this prospectus. Ask your investment professional for more information. Account options Use your account application to select options and privileges for your account. You can change your selections at any time by sending a completed account options form to the transfer agent. You may be required to obtain a signature guarantee to make certain changes to an existing account. Call or write to the transfer agent for account applications, account options forms and other account information: Pioneer Investment Management Shareholder Services, Inc. P.O. Box 55150 Boston, Massachusetts 02205-5150 Telephone 1-800-665-8839 Telephone transaction privileges If your account is registered in your name, you can exchange or sell Class Y shares by telephone. If you do not want your account to have telephone transaction privileges, you must indicate that choice on your account application or by writing to the transfer agent. When you request a telephone transaction the transfer agent will try to confirm that the request is genuine. The transfer agent records the call, requires the caller to 14 provide validating information for the account and sends you a written confirmation. The fund may implement other confirmation procedures from time to time. Different procedures may apply if you have a non-U.S. account or if your account is registered in the name of an institution, broker-dealer or other third party. - -------------------------------------------------------------------------------- By phone If you want to place your telephone transaction by speaking to a shareowner services representative, call 1-800-665-8839 between 9:00 a.m. and 5:30 p.m. Eastern time on any weekday that the New York Stock Exchange is open. - -------------------------------------------------------------------------------- 15 Buying, exchanging and selling shares General rules on buying, exchanging and selling your fund shares Share price If you place an order to purchase, exchange or sell shares with the transfer agent or a broker-dealer by the close of regular trading on the New York Stock Exchange (currently 4:00 p.m. Eastern time), your transaction will be completed at the share price determined as of the close of trading on the New York Stock Exchange on that day. If your order is placed with the transfer agent or a broker-dealer after 4:00 p.m., or your order is not in good order, your transaction will be completed at the share price next determined after your order is received in good order by the fund. The broker-dealer is responsible for transmitting your order to the fund in a timely manner. - -------------------------------------------------------------------------------- Good order means that: o You have provided adequate instructions o There are no outstanding claims against your account o There are no transaction limitations on your account o The purchase payment has cleared for shares you are requesting to redeem o If you have any fund share certificates, you submit them and they are signed by each record owner exactly as the shares are registered o Your request includes a signature guarantee if you: - Are selling over $100,000 worth of shares and - Want the sale proceeds sent to an address other than your bank account of record or - Want the sale proceeds to be made payable to someone other than the account's record owners or - The account registration, address of record or bank account of record has changed within the last 30 days - Are selling or exchanging over $5 million worth of shares - Are transferring the sale proceeds to a Pioneer mutual fund account with a different registration - -------------------------------------------------------------------------------- Buying You can buy Class Y shares at net asset value per share. The fund does not impose any initial, contingent deferred or asset based sales charge on Class Y shares. The distributor may reject any order until it has confirmed it in writing and received payment. You may use securities you own to purchase shares of the fund provided that Pioneer, in its sole discretion, determines that the securities are consistent with the fund's objective and policies and their acquisition is in the best interests of the 16 fund. If the fund accepts your securities, they will be valued for purposes of determining the number of fund shares to be issued to you in the same way the fund will value the securities for purposes of determining its net asset value. For federal income tax purposes, you may be taxed in the same manner as if you sold the securities that you exchange for cash in an amount equal to the value of the fund shares that you receive in exchange. Your sales charge for purchases of fund shares will be based upon the value of the fund shares that you receive. Your broker may also impose a fee in connection with processing your purchase of fund shares with securities. Minimum investment amount Your initial Class Y share investment must be at least $5 million. This amount may be invested in one or more of the Pioneer mutual funds that currently offer Class Y shares. There is no minimum additional investment amount. The fund may waive the initial investment amount. Waivers of the minimum investment amount The fund will accept an initial investment of less than $5 million if: (a) The investment is made by a trust company or bank trust department which is initially investing at least $1 million in any of the Pioneer mutual funds and, at the time of the purchase, such assets are held in a fiduciary, advisory, custodial or similar capacity over which the trust company or bank trust department has full or shared investment discretion; or (b) The investment is at least $1 million in any of the Pioneer mutual funds and the purchaser is an insurance company separate account; or (c) The account is not represented by a broker/dealer and the investment is made by (1) an ERISA-qualified retirement plan that meets the requirements of Section 401 of the Internal Revenue Code, (2) an employer-sponsored retirement plan that meets the requirements of Sections 403 or 457 of the Internal Revenue Code, (3) a private foundation that meets the requirements of Section 501(c)(3) of the Internal Revenue Code or (4) an endowment or other organization that meets the requirements of Section 509(a)(1) of the Internal Revenue Code; or (d) The investment is made by an employer-sponsored retirement plan established for the benefit of (1) employees of Pioneer or its affiliates, or (2) employees or the affiliates of broker-dealers who have a Class Y shares sales agreement with the distributor; or (e) The investment is made through certain mutual fund programs sponsored by qualified intermediaries, such as broker-dealers and investment advisers. In each case, the intermediary has entered into an agreement with Pioneer to include Class Y shares of the Pioneer mutual funds in their program. The 17 Buying, exchanging and selling shares intermediary provides investors participating in the program with additional services, including advisory, asset allocation, recordkeeping or other services. You should ask your investment firm if it offers and you are eligible to participate in such a mutual fund program and whether participation in the program is consistent with your investment goals. The intermediaries sponsoring or participating in these mutual fund programs may also offer their clients other classes of shares of the funds and investors may receive different levels of services or pay different fees depending upon the class of shares included in the program. Investors should consider carefully any separate transaction and other fees charged by these programs in connection with investing in each available share class before selecting a share class; or (f) The investment is made by another Pioneer fund The fund reserves the right to waive the initial investment minimum in other circumstances. Identity verification To help the government fight the funding of terrorism and money laundering activities, federal law requires all financial institutions to obtain, verify and record information that identifies each person who opens an account. When you open an account, you will need to supply your name, address, date of birth, and other information that will allow the fund to identify you. The fund may close your account if we cannot adequately verify your identity. The redemption price will be the net asset value (less applicable sales charges) on the date of redemption. Exchanging You may exchange your Class Y shares for the Class Y shares of another Pioneer mutual fund. Your exchange request must be for at least $1,000. The fund allows you to exchange your Class Y shares at net asset value without charging you either an initial or contingent deferred sales charge. Before you request an exchange, consider each fund's investment objective and policies as described in the fund's prospectus. Selling Your Class Y shares will be sold at net asset value per share next calculated after the fund or its authorized agent, such as broker-dealers, receives your request in good order. If a signature guarantee is required, you must submit your request in writing. The fund generally will send your sale proceeds by check, bank wire or electronic funds transfer. Normally you will be paid within seven days. If you recently purchased the shares being sold, the fund may delay payment of the sale 18 proceeds until your check has cleared. This may take up to 15 calendar days from the purchase date. If you are selling shares from a non-retirement account or certain IRAs, you may use any of the methods described below. If you are selling shares from a retirement account other than an IRA, you must make your request in writing. - -------------------------------------------------------------------------------- Other requirements If you must use a written request to exchange or sell your Class Y shares and your account is registered in the name of a corporation or other fiduciary you must include the name of an authorized person and a certified copy of a current corporate resolution, certificate of incumbency or similar legal document showing that the named individual is authorized to act on behalf of the record owner. - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- You may have to pay income taxes on a sale or an exchange. - -------------------------------------------------------------------------------- 19 Buying, exchanging and selling shares Buying shares In writing, by mail You can purchase Class Y shares by mailing a check to the transfer agent.

An investor may use short-term trading as a strategy, for example, if the investor believes that the valuation of the fund's portfolio securities for purposes of calculating its net asset value does not fully reflect the then current fair market value of those holdings. The fund discourages, and does not take any intentional action to accommodate, excessive and short-term trading practices, such as market timing. Although there is no generally applied standard in the marketplace as to what level of trading activity is excessive, we may consider trading in the fund's shares to be excessive for a variety of reasons, such as if: o You sell shares within a short period of time after the shares were purchased; o You make two or more purchases and redemptions within a short period of time; o You enter into a series of transactions that is indicative of a timing pattern or strategy; or o We reasonably believe that you have engaged in such practices in connection with other mutual funds. The fund's Board of Trustees has adopted policies and procedures with respect to frequent purchases and redemptions of fund shares by fund investors. Pursuant to these policies and procedures, we monitor selected trades on a daily basis in an effort to detect excessive short-term trading. If we determine that an investor or a client of a broker has engaged in excessive short-term trading that we believe may be harmful to the fund, we will ask the investor or broker to cease such activity and we will refuse to process purchase orders (including purchases by exchange) of such investor, broker or accounts that we believe are under their control. In determining whether to take such actions, we seek to act in a manner that is consistent with the best interests of the fund's shareholders. While we use our reasonable efforts to detect excessive trading activity, there can be no assurance that our efforts will be successful or that market timers will not employ tactics designed to evade detection. If we are not successful, your return from an investment in the fund may be adversely affected. Frequently, fund shares are held through omnibus accounts maintained by financial intermediaries such as brokers and retirement plan administrators, where the holdings of multiple shareholders, such as all the clients of a particular broker, are aggregated. Our ability to monitor trading practices by investors purchasing shares through omnibus accounts is limited and dependent upon the cooperation of the financial intermediary in taking steps to limit this type of activity. The fund may reject a purchase or exchange order before its acceptance or an order prior to issuance of shares. The fund may also restrict additional purchases or exchanges in an account. Each of these steps may be taken, for any reason, without 24 prior notice, including transactions that the fund believes are requested on behalf of market timers. The fund reserves the right to reject any purchase request by any investor or financial institution if the fund believes that any combination of trading activity in the account or related accounts is potentially disruptive to the fund. A prospective investor whose purchase or exchange order is rejected will not achieve the investment results, whether gain or loss, that would have been realized if the order were accepted and an investment made in the fund. The fund and its shareholders do not incur any gain or loss as a result of a rejected order. The fund may impose further restrictions on trading activities by market timers in the future. The fund's prospectus will be amended or supplemented to reflect any material additional restrictions on trading activities intended to prevent excessive trading. Account options Distribution options The fund offers three distribution options. Any fund shares you buy by reinvesting distributions will be priced at the applicable net asset value per share. (1) Unless you indicate another option on your account application, any dividends and capital gain distributions paid to you by the fund will automatically be invested in additional fund shares. (2) You may elect to have the amount of any dividends paid to you in cash and any capital gain distributions reinvested in additional shares. (3) You may elect to have the full amount of any dividends and/or capital gain distributions paid to you in cash. Options (2) or (3) are not available to retirement plan accounts or accounts with a current value of less than $500. If your distribution check is returned to the transfer agent or you do not cash the check for six months or more, the transfer agent may reinvest the amount of the check in your account and automatically change the distribution option on your account to option (1) until you request a different option in writing. If the amount of a distribution check would be less than $10, the fund may reinvest the amount instead of sending a check. Additional shares will be purchased at the then current net asset value. 25 Buying, exchanging and selling shares Shareowner services Pioneer website www.pioneerinvestments.com The website includes a full selection of information on mutual fund investing. You can also use the website to get: o Your current account information o Prices, returns and yields of all publicly available Pioneer mutual funds o Prospectuses, statements of additional information and shareowner reports for all the Pioneer mutual funds o A copy of Pioneer's privacy notice FactFone(SM) 1-800-225-4321 You can use FactFone(SM) to: o Obtain current information on your Pioneer mutual fund accounts o Inquire about the prices and yields of all publicly available Pioneer mutual funds o Request account statements If your account is registered in the name of a broker-dealer or other third party, you may not be able to use FactFone(SM) to obtain account information. Confirmation statements The transfer agent maintains an account for each investment firm or individual shareowner and records all account transactions. You will be sent confirmation statements showing the details of your transactions as they occur, except automatic investment plan transactions, which are confirmed quarterly. If you have more than one Pioneer mutual fund account registered in your name, the Pioneer combined account statement will be mailed to you each quarter. Tax information In January of each year, the fund will mail you information about the tax status of the dividends and distributions paid to you by the fund. Privacy The fund has a policy that protects the privacy of your personal information. A copy of Pioneer's privacy notice was given to you at the time you opened your account. The fund will send you a copy of the privacy notice each year. You may also obtain the privacy notice by calling the transfer agent or through Pioneer's website. 26 Shareowner account policies Signature guarantees and other requirements You are required to obtain a signature guarantee when: o Requesting certain types of exchanges or sales of fund shares o Requesting certain types of changes for your existing account You can obtain a signature guarantee from most broker-dealers, banks, credit unions (if authorized under state law) and federal savings and loan associations. You cannot obtain a signature guarantee from a notary public. The Pioneer funds generally accept only medallion signature guarantees. A medallion signature guarantee may be obtained from a domestic bank or trust company, broker, dealer, clearing agency, savings association, or other financial institution that is participating in a medallion program recognized by the Securities Transfer Association. Signature guarantees from financial institutions that are not participating in one of these programs are not accepted as medallion signature guarantees. The fund may accept other forms of guarantee from financial intermediaries in limited circumstances. Fiduciaries and corporations are required to submit additional documents to sell fund shares. Minimum account size The fund requires that you maintain a minimum account value of $500. If you hold less than $500 in your account, the fund reserves the right to notify you that it intends to sell your shares and close your account. You will be given 60 days from the date of the notice to make additional investments to avoid having your shares sold. This policy does not apply to certain qualified retirement plan accounts. Telephone and website access You may have difficulty contacting the fund by telephone or accessing pioneerinvestments.com during times of market volatility or disruption in telephone or Internet service. On New York Stock Exchange holidays or on days when the exchange closes early, Pioneer will adjust the hours for the telephone center accordingly. If you are unable to access pioneerinvestments.com or reach the fund by telephone, you should communicate with the fund in writing. Share certificates The fund does not offer share certificates. Shares are electronically recorded. Other policies The fund and the distributor reserve the right to: o reject any purchase or exchange order for any reason, without prior notice 27 Buying, exchanging and selling shares o charge a fee for exchanges or to modify, limit or suspend the exchange privilege at any time without notice. The fund will provide 60 days' notice of material amendments to or termination of the exchange privilege o revise, suspend, limit or terminate the account options or services available to shareowners at any time, except as required by the rules of the Securities and Exchange Commission The fund reserves the right to: o stop offering Class Y shares o suspend transactions in shares when trading on the New York Stock Exchange is closed or restricted, when the Securities and Exchange Commission determines an emergency or other circumstances exist that make it impracticable for the fund to sell or value its portfolio securities o redeem in kind by delivering to you portfolio securities owned by the fund rather than cash. Securities you receive this way may increase or decrease in value while you hold them and you may incur brokerage and transaction charges and tax liability when you convert the securities to cash o charge transfer, shareholder servicing or similar agent fees, such as an account maintenance fee for small balance accounts, directly to accounts upon at least 30 days' notice. The fund may do this by deducting the fee from your distribution of dividends and/or by redeeming shares to the extent necessary to cover the fee 28 Dividends, capital gains and taxes Dividends and capital gains The fund generally pays any distributions of net short- and long-term capital gains in November. The fund generally pays dividends from any net investment income in December. The fund may also pay dividends and capital gain distributions at other times if necessary for the fund to avoid U.S. federal income or excise tax. If you invest in the fund close to the time that the fund makes a distribution, generally you will pay a higher price per share and you will pay taxes on the amount of the distribution whether you reinvest the distribution or receive it as cash. Taxes For U.S. federal income tax purposes, distributions from the fund's net long-term capital gains (if any) are considered long-term capital gains and may be taxable to you at different maximum rates depending upon their source and other factors. Distributions from the fund's net short-term capital gains are taxable as ordinary income. Dividends are taxable either as ordinary income or, if so designated by the fund and certain other conditions, including holding period requirements, are met by the fund and the shareholder, as "qualified dividend income" taxable to individual shareholders at a maximum 15% U.S. federal income tax rate. Dividends and distributions are taxable, whether you take payment in cash or reinvest them to buy additional fund shares. When you sell or exchange fund shares you will generally recognize a capital gain or capital loss in an amount equal to the difference between the net amount of sale proceeds (or, in the case of an exchange, the fair market value of the shares) that you receive and your tax basis for the shares that you sell or exchange. In January of each year the fund will mail to you information about your dividends, distributions and any shares you sold in the previous calendar year. You must provide your social security number or other taxpayer identification number to the fund along with the certifications required by the Internal Revenue Service when you open an account. If you do not or if it is otherwise legally required to do so, the fund will withhold 28% "backup withholding" tax from your dividends and distributions, sale proceeds and any other payments to you. You should ask your tax adviser about any federal, state, local and foreign tax considerations, including possible additional withholding taxes for non-U.S. shareholders. You may also consult the fund's statement of additional information for a more detailed discussion of qualified dividend income and other U.S. federal income tax considerations that may affect the fund and its shareowners. - -------------------------------------------------------------------------------- Sales and exchanges may be taxable transactions to shareowners. - -------------------------------------------------------------------------------- 29 Financial highlights The financial highlights table helps you understand the fund's financial performance since the inception of Class Y shares. Certain information reflects financial results for a single fund share. The total returns in the table represent the rate that you would have earned or lost on an investment in Class Y shares of the fund (assuming reinvestment of all dividends and distributions).

FUND HISTORY The fund is a diversified open-end management investment company organized as a Delaware statutory trust on December 8, 1997. The fund is a series of Pioneer Independence Fund (the "Trust"). Pioneer Investment Management Inc., ("Pioneer") is the fund's investment adviser. 2. INVESTMENT POLICIES, RISKS AND RESTRICTIONS The prospectuses present the investment objective and the principal investment strategies and risks of the fund. This section supplements the disclosure in the fund's prospectuses and provides additional information on the fund's investment policies or restrictions. Restrictions or policies stated as a maximum percentage of the fund's assets are only applied immediately after a portfolio investment to which the policy or restriction is applicable (other than the limitations on borrowing and illiquid securities). Accordingly, any later increase or decrease resulting from a change in values, net assets or other circumstances will not be considered in determining whether the investment complies with the fund's restrictions and policies. Illiquid Securities The fund will not invest more than 15% of its net assets in illiquid and other securities that are not readily marketable. Repurchase agreements maturing in more than seven days will be included for purposes of the foregoing limit. Securities subject to restrictions on resale under the Securities Act of 1933, as amended (the "1933 Act"), are considered illiquid unless they are eligible for resale pursuant to Rule 144A or another exemption from the registration requirements of the 1933 Act and are determined to be liquid by Pioneer. Pioneer determines the liquidity of Rule 144A and other restricted securities according to procedures adopted by the Board of Trustees. Under the direction of the Board of Trustees, Pioneer monitors the application of these guidelines and procedures. The inability of the fund to dispose of illiquid investments readily or at reasonable prices could impair the fund's ability to raise cash for redemptions or other purposes. If the fund sold restricted securities other than pursuant to an exception from registration under the 1933 Act such as Rule 144A, it may be deemed to be acting as an underwriter and subject to liability under the 1933 Act. Investments in Initial Public Offerings To the extent consistent with its investment objective, the fund may invest in initial public offerings ("IPOs") of equity securities. The market for such securities may be more volatile and entail greater risk of loss than investments in more established companies. Investments in initial public offerings may represent a significant portion of the fund's investment performance. The fund cannot assure that investments in initial public offerings will continue to be available to the fund or, if available, will result in positive investment performance. In addition, as the fund's portfolio grows in size, the impact of investments in initial public offerings on the overall performance of the fund is likely to decrease. 2 Debt Securities Selection In selecting debt securities for the fund, Pioneer gives primary consideration to the fund's investment objective, the attractiveness of the market for debt securities given the outlook of Pioneer for the equity markets and the fund's liquidity requirements. Once Pioneer determines to allocate a portion of the fund's assets to debt securities, Pioneer generally focuses on short-term instruments to provide liquidity and may invest in a range of fixed income securities if the fund is investing in such instruments for income or capital gains. Pioneer selects individual securities based on broad economic factors and issuer specific factors including the terms of the securities (such as yields compared to U.S. Treasuries or comparable issues), liquidity and rating, sector and issuer diversification. Convertible Debt Securities The fund may invest in convertible debt securities which are debt obligations convertible at a stated exchange rate or formula into common stock or other equity securities of or owned by the issuer. Convertible securities rank senior to common stocks in an issuer's capital structure and consequently may be of higher quality and entail less risk than the issuer's common stock. As with all debt securities, the market values of convertible securities tend to increase when interest rates decline and, conversely, tend to decline when interest rates increase. Short-Term Investments For temporary defensive or cash management purposes, the fund may invest in all types of short-term investments including, but not limited to, (a) commercial paper and other short-term commercial obligations; (b) obligations (including certificates of deposit and bankers' acceptances) of banks; (c) obligations issued or guaranteed by a governmental issuer, including governmental agencies or instrumentalities; (d) fixed income securities of corporate issuers; and (e) other cash equivalents or cash. Subject to the fund's restrictions regarding investment in non-U.S. securities, these securities may be denominated in any currency. Although these investments generally are rated investment grade or are determined by Pioneer to be of equivalent credit quality, the fund may also invest in these instruments if they are rated below investment grade in accordance with its investment objective, policies and restrictions. Debt Securities Rating Criteria Investment grade debt securities are those rated "BBB" or higher by Standard & Poor's Ratings Group ("Standard & Poor's") or the equivalent rating of other nationally recognized statistical rating organizations. Debt securities rated BBB are considered medium grade obligations with speculative characteristics, and adverse economic conditions or changing circumstances may weaken the issuer's ability to pay interest and repay principal. If the rating of an investment grade debt security falls below investment grade,, Pioneer will consider if any action is appropriate in light of the fund's investment objective and policies. Below investment grade debt securities are those rated "BB" and below by Standard & Poor's or the equivalent rating of other nationally recognized statistical rating organizations. See "Appendix A" for a description of rating categories. The fund may invest in debt securities rated "C" or better, or comparable unrated securities. 3 Below investment grade debt securities or comparable unrated securities are commonly referred to as "junk bonds" and are considered predominantly speculative and may be questionable as to principal and interest payments. Changes in economic conditions are more likely to lead to a weakened capacity to make principal payments and interest payments. The amount of high yield securities outstanding has proliferated as an increasing number of issuers have used high yield securities for corporate financing. An economic downturn could severely affect the ability of highly leveraged issuers to service their debt obligations or to repay their obligations upon maturity. Factors having an adverse impact on the market value of lower quality securities will have an adverse effect on the fund's net asset value to the extent that it invests in such securities. In addition, the fund may incur additional expenses to the extent it is required to seek recovery upon a default in payment of principal or interest on its portfolio holdings. The secondary market for high yield securities may not be as liquid as the secondary market for more highly rated securities, a factor which may have an adverse effect on the fund's ability to dispose of a particular security when necessary to meet its liquidity needs. Under adverse market or economic conditions, the secondary market for high yield securities could contract further, independent of any specific adverse changes in the condition of a particular issuer. As a result, the fund could find it more difficult to sell these securities or may be able to sell the securities only at prices lower than if such securities were widely traded. Prices realized upon the sale of such lower rated or unrated securities, under these circumstances, may be less than the prices used in calculating the fund's net asset value. Since investors generally perceive that there are greater risks associated with lower quality debt securities of the type in which the fund may invest a portion of its assets, the yields and prices of such securities may tend to fluctuate more than those for higher rated securities. In the lower quality segments of the debt securities market, changes in perceptions of issuers' creditworthiness tend to occur more frequently and in a more pronounced manner than do changes in higher quality segments of the debt securities market, resulting in greater yield and price volatility. Lower rated and comparable unrated debt securities tend to offer higher yields than higher rated securities with the same maturities because the historical financial condition of the issuers of such securities may not have been as strong as that of other issuers. However, lower rated securities generally involve greater risks of loss of income and principal than higher rated securities. Pioneer will attempt to reduce these risks through portfolio diversification and by analysis of each issuer and its ability to make timely payments of income and principal, as well as broad economic trends and corporate developments. For purposes of the fund's credit quality policies, if a security receives different ratings from nationally recognized statistical rating organizations, the fund will use the rating chosen by the portfolio manager as most representative of the security's credit quality. If a rating organization downgrades the quality rating assigned to one or more of the fund's portfolio securities, Pioneer will consider what actions, if any, are appropriate including selling the downgraded security or purchasing additional investment grade securities of the appropriate credit quality as soon as it is prudent to do so. U.S. Government Securities U.S. government securities in which the fund invests include debt obligations of varying maturities issued by the U.S. Treasury or issued or guaranteed by an agency or instrumentality of the U.S. government, including the Federal Housing Administration, Federal Financing Bank, Farmers Home Administration, Export-Import Bank of the U.S., Small Business Administration, Government National Mortgage Association ("GNMA"), General Services Administration, Central Bank for Cooperatives, Federal Farm Credit Banks, Federal Home Loan Banks ("FHLBs"), Federal Home Loan Mortgage Corporation 4 ("FHLMC"), Federal National Mortgage Association ("FNMA"), Maritime Administration, Tennessee Valley Authority, District of Columbia Armory Board, Resolution Trust Corporation and various institutions that previously were or currently are part of the Farm Credit System (which has been undergoing reorganization since 1987). Some U.S. government securities, such as U.S. Treasury bills, Treasury notes and Treasury bonds, which differ only in their interest rates, maturities and times of issuance, are supported by the full faith and credit of the United States. Others are supported by: (i) the right of the issuer to borrow from the U.S. Treasury, such as securities of the FHLBs; (ii) the discretionary authority of the U.S. government to purchase the agency's obligations, such as securities of the FNMA; or (iii) only the credit of the issuer. No assurance can be given that the U.S. government will provide financial support in the future to U.S. government agencies, authorities or instrumentalities that are not supported by the full faith and credit of the United States. Securities guaranteed as to principal and interest by the U.S. government, its agencies, authorities or instrumentalities include: (i) securities for which the payment of principal and interest is backed by an irrevocable letter of credit issued by the U.S. government or any of its agencies, authorities or instrumentalities; and (ii) participations in loans made to non-U.S. governments or other entities that are so guaranteed. The secondary market for certain of these participations is limited and, therefore, may be regarded as illiquid. U.S. government securities may include zero coupon securities that may be purchased when yields are attractive and/or to enhance portfolio liquidity. Zero coupon U.S. government securities are debt obligations that are issued or purchased at a significant discount from face value. The discount approximates the total amount of interest the security will accrue and compound over the period until maturity or the particular interest payment date at a rate of interest reflecting the market rate of the security at the time of issuance. Zero coupon U.S. government securities do not require the periodic payment of interest. These investments benefit the issuer by mitigating its need for cash to meet debt service, but generally require a higher rate of return to attract investors who are willing to defer receipt of cash. These investments may experience greater volatility in market value than U.S. government securities that make regular payments of interest. The fund accrues income on these investments for tax and accounting purposes, which is distributable to shareholders and which, because no cash is received at the time of accrual, may require the liquidation of other portfolio securities to satisfy the fund's distribution obligations, in which case the fund will forgo the purchase of additional income producing assets with these funds. Zero coupon U.S. government securities include STRIPS and CUBES, which are issued by the U.S. Treasury as component parts of U.S. Treasury bonds and represent scheduled interest and principal payments on the bonds. Debt Obligations of Non-U.S. Governments The fund may invest in debt obligations of non-U.S. governments. An investment in debt obligations of non-U.S. governments and their political subdivisions (sovereign debt) involves special risks that are not present in corporate debt obligations. The non-U.S. issuer of the sovereign debt or the non-U.S. governmental authorities that control the repayment of the debt may be unable or unwilling to repay principal or interest when due, and the fund may have limited recourse in the event of a default. During periods of economic uncertainty, the market prices of sovereign debt may be more volatile than prices of debt obligations of U.S. issuers. In the past, certain non-U.S. countries have encountered difficulties in servicing their debt obligations, withheld payments of principal and interest and declared moratoria on the payment of principal and interest on their sovereign debt. A sovereign debtor's willingness or ability to repay principal and pay interest in a timely manner may be affected by, among other factors, its cash flow situation, the extent of its foreign currency reserves, the availability of sufficient foreign exchange, the relative size of the debt service burden, the sovereign debtor's policy toward its principal international lenders and local political constraints. Sovereign debtors 5 may also be dependent on expected disbursements from non-U.S. governments, multinational agencies and other entities to reduce principal and interest arrearages on their debt. The failure of a sovereign debtor to implement economic reforms, achieve specified levels of economic performance or repay principal or interest when due may result in the cancellation of third-party commitments to lend funds to the sovereign debtor, which may further impair such debtor's ability or willingness to service its debts. Risks of Non-U.S. Investments Investing in securities of non-U.S. issuers involves considerations and risks not typically associated with investing in the securities of issuers in the U.S. These risks are heightened with respect to investments in countries with emerging markets and economies. The risks of investing in securities of non-U.S. issuers generally, or in issuers with significant exposure to non-U.S. markets may be related, among other things, to (i) differences in size, liquidity and volatility of, and the degree and manner of regulation of, the securities markets of certain non-U.S. markets compared to the securities markets in the U.S.; (ii) economic, political and social factors; and (iii) foreign exchange matters, such as restrictions on the repatriation of capital, fluctuations in exchange rates between the U.S. dollar and the currencies in which the fund's portfolio securities are quoted or denominated, exchange control regulations and costs associated with currency exchange. The political and economic structures in certain countries, particularly emerging markets, are expected to undergo significant evolution and rapid development, and such countries may lack the social, political and economic stability characteristic of more developed countries. Non-U.S. Securities Markets and Regulations. There may be less publicly available information about non-U.S. markets and issuers than is available with respect to U.S. securities and issuers. Non-U.S. companies generally are not subject to accounting, auditing and financial reporting standards, practices and requirements comparable to those applicable to U.S. companies. The trading markets for most non-U.S. securities are generally less liquid and subject to greater price volatility than the markets for comparable securities in the U.S. The markets for securities in certain emerging markets are in the earliest stages of their development. Even the markets for relatively widely traded securities in certain non-U.S. markets, including emerging market countries, may not be able to absorb, without price disruptions, a significant increase in trading volume or trades of a size customarily undertaken by institutional investors in the U.S. Additionally, market making and arbitrage activities are generally less extensive in such markets, which may contribute to increased volatility and reduced liquidity. The less liquid a market, the more difficult it may be for the fund to accurately price its portfolio securities or to dispose of such securities at the times determined by Pioneer to be appropriate. The risks associated with reduced liquidity may be particularly acute in situations in which the fund's operations require cash, such as in order to meet redemptions and to pay its expenses. Economic, Political and Social Factors. Certain countries, including emerging markets, may be subject to a greater degree of economic, political and social instability than is the case in the U.S. and Western European countries. Such instability may result from, among other things: (i) authoritarian governments or military involvement in political and economic decision making; (ii) popular unrest associated with demands for improved economic, political and social conditions; (iii) internal insurgencies; (iv) hostile relations with neighboring countries; and (v) ethnic, religious and racial disaffection and conflict. Such economic, political and social instability could significantly disrupt the financial markets in such countries and the ability of the issuers in such countries to repay their obligations. Investing in emerging market countries also involves the risk of expropriation, nationalization, confiscation of assets and property or the imposition of restrictions on foreign investments and on repatriation of capital invested. In the event of such expropriation, nationalization or other confiscation in any emerging country, the fund could lose its entire investment in that country. 6 Certain emerging market countries restrict or control foreign investment in their securities markets to varying degrees. These restrictions may limit the fund's investment in those markets and may increase the expenses of the fund. In addition, the repatriation of both investment income and capital from certain markets in the region is subject to restrictions such as the need for certain governmental consents. Even where there is no outright restriction on repatriation of capital, the mechanics of repatriation may affect certain aspects of the fund's operation. Economies in individual countries may differ favorably or unfavorably from the U.S. economy in such respects as growth of gross domestic product, rates of inflation, currency valuation, capital reinvestment, resource self-sufficiency and balance of payments positions. Many countries have experienced substantial, and in some cases extremely high, rates of inflation for many years. Inflation and rapid fluctuations in inflation rates have had, and may continue to have, very negative effects on the economies and securities markets of certain emerging countries. Unanticipated political or social developments may affect the values of the fund's investments and the availability to the fund of additional investments in such countries. In the past, the economies, securities and currency markets of many emerging markets have experienced significant disruption and declines. There can be no assurance that these economic and market disruptions might not occur again. Economies in emerging market countries generally are dependent heavily upon international trade and, accordingly, have been and may continue to be affected adversely by trade barriers, exchange controls, managed adjustments in relative currency values and other protectionist measures imposed or negotiated by the countries with which they trade. These economies also have been, and may continue to be, affected adversely by economic conditions in the countries with which they trade. Currency Risks. The value of the securities quoted or denominated in foreign currencies may be adversely affected by fluctuations in the relative currency exchange rates and by exchange control regulations. The fund's investment performance may be negatively affected by a devaluation of a currency in which the fund's investments are quoted or denominated. Further, the fund's investment performance may be significantly affected, either positively or negatively, by currency exchange rates because the U.S. dollar value of securities quoted or denominated in another currency will increase or decrease in response to changes in the value of such currency in relation to the U.S. dollar. Custodian Services and Related Investment Costs. Custodial services and other costs relating to investment in international securities markets generally are more expensive than in the U.S. Such markets have settlement and clearance procedures that differ from those in the U.S. In certain markets there have been times when settlements have been unable to keep pace with the volume of securities transactions, making it difficult to conduct such transactions. The inability of the fund to make intended securities purchases due to settlement problems could cause the fund to miss attractive investment opportunities. Inability to dispose of a portfolio security caused by settlement problems could result either in losses to the fund due to a subsequent decline in value of the portfolio security or could result in possible liability to the fund. In addition, security settlement and clearance procedures in some emerging countries may not fully protect the fund against loss or theft of its assets. Withholding and Other Taxes. The fund will be subject to taxes, including withholding taxes, on income (possibly including, in some cases, capital gains) that are or may be imposed by certain countries with respect to the fund's investments in such countries. These taxes will reduce the return achieved by the fund. Treaties between the U.S. and such countries may not be available to reduce the otherwise applicable tax rates. 7 Real Estate Investment Trusts ("REITs") and Associated Risk Factors REITs are companies that invest primarily in income producing real estate or real estate related loans or interests. REITs are generally classified as equity REITs, mortgage REITs or a combination of equity and mortgage REITs. Equity REITs invest the majority of their assets directly in real property and derive income primarily from the collection of rents. Equity REITs can also realize capital gains by selling properties that have appreciated in value. Mortgage REITs invest the majority of their assets in real estate mortgages and derive income from the collection of interest payments. REITs are not taxed on income distributed to shareholders provided they comply with the applicable requirements of the Internal Revenue Code of 1986, as amended (the "Code"). The fund will indirectly bear its proportionate share of any management and other expenses paid by REITs in which it invests in addition to the expenses paid by the fund. Debt securities issued by REITs are, for the most part, general and unsecured obligations and are subject to risks associated with REITs. Investing in REITs involves certain unique risks in addition to those risks associated with investing in the real estate industry in general. An equity REIT may be affected by changes in the value of the underlying properties owned by the REIT. A mortgage REIT may be affected by changes in interest rates and the ability of the issuers of its portfolio mortgages to repay their obligations. REITs are dependent upon the skills of their managers and are not diversified. REITs are generally dependent upon maintaining cash flows to repay borrowings and to make distributions to shareholders and are subject to the risk of default by lessees or borrowers. REITs whose underlying assets are concentrated in properties used by a particular industry, such as health care, are also subject to risks associated with such industry. REITs (especially mortgage REITs) are also subject to interest rate risks. When interest rates decline, the value of a REIT's investment in fixed rate obligations can be expected to rise. Conversely, when interest rates rise, the value of a REIT's investment in fixed rate obligations can be expected to decline. If the REIT invests in adjustable rate mortgage loans the interest rates on which are reset periodically, yields on a REIT's investments in such loans will gradually align themselves to reflect changes in market interest rates. This causes the value of such investments to fluctuate less dramatically in response to interest rate fluctuations than would investments in fixed rate obligations. REITs may have limited financial resources, may trade less frequently and in a limited volume and may be subject to more abrupt or erratic price movements than larger company securities. Historically REITs have been more volatile in price than the larger capitalization stocks included in Standard & Poor's 500 Stock Index (the "S&P 500"). Other Investment Companies The fund may invest in the securities of other investment companies to the extent that such investments are consistent with the fund's investment objective and policies and permissible under the Investment Company Act of 1940, as amended (the "1940 Act"). Under one provision of the 1940 Act, a fund may not acquire the securities of another investment company if, as a result, (i) such purchase would result in more than 3% of the total outstanding voting securities of any one investment company being held by the fund, or (ii) more than 5% of the fund's total assets would be invested in any one investment company, or (iii) more than 10% of the fund's total assets would be invested in securities of other investment companies. However, there are several provisions of the 1940 Act and rules thereunder that allow more expansive investment in investment companies. In addition, these limitations do not apply to the purchase of shares of any investment company in connection with a merger, consolidation, reorganization or acquisition of substantially all the assets of another investment company. The fund may invest in 8 money market funds managed by Pioneer in reliance on an exemptive order granted by the Securities and Exchange Commission (the "SEC"). The fund, as a holder of the securities of other investment companies, will bear its pro rata portion of the other investment companies' expenses, including advisory fees. These expenses are in addition to the direct expenses of the fund's own operations. Exchange Traded Funds Subject to the limitations on investment in other investment companies, the fund may invest in exchange traded funds (ETFs). ETFs, such as SPDRs, Power Shares QQQ (QQQQs), iShares and various country index funds, are funds whose shares are traded on a national exchange or the National Association of Securities Dealers' Automatic Quotation System (NASDAQ). ETFs may be based on underlying equity or fixed income securities. SPDRs, for example, seek to provide investment results that generally correspond to the performance of the component common stocks of the S&P 500. ETFs do not sell individual shares directly to investors and only issue their shares in large blocks known as "creation units." The investor purchasing a creation unit then sells the individual shares on a secondary market. Therefore, the liquidity of ETFs depends on the adequacy of the secondary market. There can be no assurance that an ETF's investment objective will be achieved. ETFs based on an index may not replicate and maintain exactly the composition and relative weightings of securities in the index. ETFs are subject to the risks of investing in the underlying securities. The fund, as a holder of the securities of the ETF, will bear its pro rata portion of the ETF's expenses, including advisory fees. These expenses are in addition to the direct expenses of the fund's own operations. Investments in Depositary Receipts The fund may hold securities of non-U.S. issuers in the form of American Depositary Receipts ("ADRs"), European Depositary Receipts ("EDRs"), Global Depositary Receipts ("GDRs") and other similar instruments. Generally, ADRs in registered form are designed for use in U.S. securities markets, and EDRs and GDRs and other similar global instruments in bearer form are designed for use in non-U.S. securities markets. ADRs are denominated in U.S. dollars and represent an interest in the right to receive securities of non-U.S. issuers deposited in a U.S. bank or correspondent bank. ADRs do not eliminate all the risk inherent in investing in the securities of non-U.S. issuers. However, by investing in ADRs rather than directly in equity securities of non-U.S. issuers, the fund will avoid currency risks during the settlement period for either purchases or sales. EDRs and GDRs are not necessarily denominated in the same currency as the underlying securities which they represent. For purposes of the fund's investment policies, investments in ADRs, EDRs, GDRs and similar instruments will be deemed to be investments in the underlying equity securities of non-U.S. issuers. The fund may acquire depositary receipts from banks that do not have a contractual relationship with the issuer of the security underlying the depositary receipt to issue and secure such depositary receipt. To the extent the fund invests in such unsponsored depositary receipts there may be an increased possibility that the fund may not become aware of events affecting the underlying security and thus the value of the related depositary receipt. In addition, certain benefits (i.e., rights offerings) which may be associated with the security underlying the depositary receipt may not inure to the benefit of the holder of such depositary receipt. 9 Repurchase Agreements The fund may enter into repurchase agreements with broker-dealers, member banks of the Federal Reserve System and other financial institutions. Repurchase agreements are arrangements under which the fund purchases securities and the seller agrees to repurchase the securities within a specific time and at a specific price. The repurchase price is generally higher than the fund's purchase price, with the difference being income to the fund. Under the direction of the Board of Trustees, Pioneer reviews and monitors the creditworthiness of any institution which enters into a repurchase agreement with the fund. The counterparty's obligations under the repurchase agreement are collateralized with U.S. Treasury and/or agency obligations with a market value of not less than 100% of the obligations, valued daily. Collateral is held by the fund's custodian in a segregated, safekeeping account for the benefit of the fund. Repurchase agreements afford the fund an opportunity to earn income on temporarily available cash at low risk. In the event of commencement of bankruptcy or insolvency proceedings with respect to the seller of the security before repurchase of the security under a repurchase agreement, the fund may encounter delay and incur costs before being able to sell the security. Such a delay may involve loss of interest or a decline in price of the security. If the court characterizes the transaction as a loan and the fund has not perfected a security interest in the security, the fund may be required to return the security to the seller's estate and be treated as an unsecured creditor of the seller. As an unsecured creditor, the fund would be at risk of losing some or all of the principal and interest involved in the transaction. Short Sales Against the Box The fund may sell securities "short against the box." A short sale involves the fund borrowing securities from a broker and selling the borrowed securities. The fund has an obligation to return securities identical to the borrowed securities to the broker. In a short sale against the box, the fund at all times own an equal amount of the security sold short or securities convertible into or exchangeable for, with or without payment of additional consideration, an equal amount of the security sold short. The fund intends to use short sales against the box to hedge. For example when the fund believes that the price of a current portfolio security may decline, the fund may use a short sale against the box to lock in a sale price for a security rather than selling the security immediately. In such a case, any future losses in the fund's long position should be offset by a gain in the short position and, conversely, any gain in the long position should be reduced by a loss in the short position. If the fund effects a short sale against the box at a time when it has an unrealized gain on the security, it may be required to recognize that gain as if it had actually sold the security (a "constructive sale") on the date it effects the short sale. However, such constructive sale treatment may not apply if the fund closes out the short sale with securities other than the appreciated securities held at the time of the short sale provided that certain other conditions are satisfied. Uncertainty regarding the tax consequences of effecting short sales may limit the extent to which the fund may make short sales against the box. Asset Segregation The 1940 Act requires that the fund segregate assets in connection with certain types of transactions that may have the effect of leveraging the fund's portfolio. If the fund enters into a transaction requiring segregation, such as a forward commitment, the custodian or Pioneer will segregate liquid assets in an amount required to comply with the 1940 Act. Such segregated assets will be valued at market daily. If the aggregate value of such segregated assets declines below the aggregate value required to satisfy the 1940 Act, additional liquid assets will be segregated. 10 When-Issued and Delayed Delivery Securities The fund may purchase securities, including U.S. government securities, on a when-issued basis or may purchase or sell securities for delayed delivery. In such transactions, delivery of the securities occurs beyond the normal settlement period, but no payment or delivery is made by the fund prior to the actual delivery or payment by the other party to the transaction. The fund will not earn income on these securities until delivered. The purchase of securities on a when-issued or delayed delivery basis involves the risk that the value of the securities purchased will decline prior to the settlement date. The sale of securities for delayed delivery involves the risk that the prices available in the market on the delivery date may be greater than those obtained in the sale transaction. The fund's obligations with respect to when-issued and delayed delivery transactions will be fully collateralized by segregating liquid assets with a value equal to the fund's obligations. See "Asset Segregation." Portfolio Turnover It is the policy of the fund not to engage in trading for short-term profits although portfolio turnover rate is not considered a limiting factor in the execution of investment decisions for the fund. A high rate of portfolio turnover (100% or more) involves correspondingly greater transaction costs which must be borne by the fund and its shareholders. See "Annual Fee, Expense and Other Information" for the fund's annual portfolio turnover rate. Foreign Currency Transactions The fund may engage in foreign currency transactions. These transactions may be conducted at the prevailing spot rate for purchasing or selling currency in the foreign exchange market. The fund also has authority to enter into forward foreign currency exchange contracts involving currencies of the different countries in which the fund invests as a hedge against possible variations in the foreign exchange rates between these currencies and the U.S. dollar. This is accomplished through contractual agreements to purchase or sell a specified currency at a specified future date and price set at the time of the contract. Transaction hedging is the purchase or sale of forward foreign currency contracts with respect to specific receivables or payables of the fund, accrued in connection with the purchase and sale of its portfolio securities quoted in foreign currencies. Portfolio hedging is the use of forward foreign currency contracts to offset portfolio security positions denominated or quoted in such foreign currencies. There is no guarantee that the fund will be engaged in hedging activities when adverse exchange rate movements occur. The fund will not attempt to hedge all of its foreign portfolio positions and will enter into such transactions only to the extent, if any, deemed appropriate by Pioneer. Hedging against a decline in the value of a currency does not eliminate fluctuations in the prices of portfolio securities or prevent losses if the prices of such securities decline. Such transactions also limit the opportunity for gain if the value of the hedged currency should rise. Moreover, it may not be possible for the fund to hedge against a devaluation that is so generally anticipated that the fund is not able to contract to sell the currency at a price above the devaluation level it anticipates. The fund may also engage in cross-hedging by using forward contracts in one currency to hedge against fluctuations in the value of securities denominated in a different currency, if Pioneer determines that there is a pattern of correlation between the two currencies. Cross-hedging may also include entering into a forward transaction involving two foreign currencies, using one foreign currency as a proxy for the U.S. 11 dollar to hedge against variations in the other foreign currency, if Pioneer determines that there is a pattern of correlation between the proxy currency and the U.S. dollar. The cost to the fund of engaging in foreign currency transactions varies with such factors as the currency involved, the size of the contract, the length of the contract period, differences in interest rates between the two currencies and the market conditions then prevailing. Since transactions in foreign currency and forward contracts are usually conducted on a principal basis, no fees or commissions are involved. The fund may close out a forward position in a currency by selling the forward contract or by entering into an offsetting forward contract. The precise matching of the forward contract amounts and the value of the securities involved will not generally be possible because the future value of such securities in foreign currencies will change as a consequence of market movements in the value of those securities between the date on which the contract is entered into and the date it matures. Using forward contracts to protect the value of the fund's portfolio securities against a decline in the value of a currency does not eliminate fluctuations in the underlying prices of the securities. It simply establishes a rate of exchange which the fund can achieve at some future point in time. The precise projection of short-term currency market movements is not possible, and short-term hedging provides a means of fixing the U.S. dollar value of only a portion of the fund's foreign assets. While the fund will enter into forward contracts to reduce currency exchange rate risks, transactions in such contracts involve certain other risks. While the fund may benefit from such transactions, unanticipated changes in currency prices may result in a poorer overall performance for the fund than if it had not engaged in any such transactions. Moreover, there may be imperfect correlation between the fund's portfolio holdings of securities quoted or denominated in a particular currency and forward contracts entered into by the fund. Such imperfect correlation may cause the fund to sustain losses which will prevent the fund from achieving a complete hedge or expose the fund to risk of foreign exchange loss. Over-the-counter markets for trading foreign forward currency contracts offer less protection against defaults than is available when trading in currency instruments on an exchange. Since a forward foreign currency exchange contract is not guaranteed by an exchange or clearinghouse, a default on the contract would deprive the fund of unrealized profits or force the fund to cover its commitments for purchase or resale, if any, at the current market price. If the fund enters into a forward contract to purchase foreign currency, the custodian or Pioneer will segregate liquid assets. See "Asset Segregation." Options on Foreign Currencies The fund may purchase and write options on foreign currencies for hedging purposes in a manner similar to that of transactions in forward contracts. For example, a decline in the dollar value of a foreign currency in which portfolio securities are quoted or denominated will reduce the dollar value of such securities, even if their value in the foreign currency remains constant. In an attempt to protect against such decreases in the value of portfolio securities, the fund may purchase put options on the foreign currency. If the value of the currency declines, the fund will have the right to sell such currency for a fixed amount of dollars which exceeds the market value of such currency. This would result in a gain that may offset, in whole or in part, the negative effect of currency depreciation on the value of the fund's securities quoted or denominated in that currency. 12 Conversely, if a rise in the dollar value of a currency is projected for those securities to be acquired, thereby increasing the cost of such securities, the fund may purchase call options on such currency. If the value of such currency increases, the purchase of such call options would enable the fund to purchase currency for a fixed amount of dollars which is less than the market value of such currency. Such a purchase would result in a gain that may offset, at least partially, the effect of any currency related increase in the price of securities the fund intends to acquire. As in the case of other types of options transactions, however, the benefit the fund derives from purchasing foreign currency options will be reduced by the amount of the premium and related transaction costs. In addition, if currency exchange rates do not move in the direction or to the extent anticipated, the fund could sustain losses on transactions in foreign currency options which would deprive it of a portion or all of the benefits of advantageous changes in such rates. The fund may also write options on foreign currencies for hedging purposes. For example, if the fund anticipated a decline in the dollar value of securities quoted or denominated in a foreign currency because of declining exchange rates, it could, instead of purchasing a put option, write a covered call option on the relevant currency. If the expected decline occurs, the option will most likely not be exercised, and the decrease in value of portfolio securities will be partially offset by the amount of the premium received by the fund. Similarly, the fund could write a put option on the relevant currency, instead of purchasing a call option, to hedge against an anticipated increase in the dollar cost of securities to be acquired. If exchange rates move in the manner projected, the put option will expire unexercised and allow the fund to offset such increased cost up to the amount of the premium. However, as in the case of other types of options transactions, the writing of a foreign currency option will constitute only a partial hedge up to the amount of the premium, only if rates move in the expected direction. If unanticipated exchange rate fluctuations occur, the option may be exercised and the fund would be required to purchase or sell the underlying currency at a loss which may not be fully offset by the amount of the premium. As a result of writing options on foreign currencies, the fund also may be required to forgo all or a portion of the benefits which might otherwise have been obtained from favorable movements in currency exchange rates. A call option written on foreign currency by the fund is "covered" if the fund owns the underlying foreign currency subject to the call, or if it has an absolute and immediate right to acquire that foreign currency without additional cash consideration. A call option is also covered if the fund holds a call on the same foreign currency for the same principal amount as the call written where the exercise price of the call held is (a) equal to or less than the exercise price of the call written or (b) greater than the exercise price of the call written if the amount of the difference is maintained by the fund in cash or liquid securities. See "Asset Segregation." The fund may close out its position in a currency option by either selling the option it has purchased or entering into an offsetting option. An exchange-traded options position may be closed out only on an options exchange which provides a secondary market for an option of the same series. Although the fund will generally purchase or write only those options for which there appears to be an active secondary market, there is no assurance that a liquid secondary market on an exchange will exist for any particular option, or at any particular time. For some options no secondary market on an exchange may exist. In such event, it might not be possible to effect closing transactions in particular options, with the result that the fund would have to exercise its options in order to realize any profit and would incur transaction costs upon the sale of underlying currencies pursuant to the exercise of put options. If the fund as a covered call option writer is unable to effect a closing purchase transaction in a secondary market, it will not be able to sell the underlying currency (or security quoted or denominated in that currency) until the option expires or it delivers the underlying currency upon exercise. 13 The fund may also use options on currencies to cross-hedge, which involves writing or purchasing options on one currency to hedge against changes in exchange rates of a different currency with a pattern of correlation. Cross-hedging may also include using a foreign currency as a proxy for the U.S. dollar, if Pioneer determines that there is a pattern of correlation between that currency and the U.S. dollar. The fund may purchase and write over-the-counter options to the extent consistent with its limitation on investments in illiquid securities. Trading in over-the-counter options is subject to the risk that the other party will be unable or unwilling to close out options purchased or written by the fund. Options on Securities and Securities Indices For hedging purposes or to seek to increase total return, the fund may purchase put and call options on any security in which it may invest or options on any securities index based on securities in which it may invest. The fund would also be able to enter into closing sale transactions in order to realize gains or minimize losses on options it has purchased. Writing Call and Put Options on Securities. A call option written by the fund obligates the fund to sell specified securities to the holder of the option at a specified price if the option is exercised at any time before the expiration date. All call options written by the fund are covered, which means that the fund will own the securities subject to the options as long as the options are outstanding, or the fund will use the other methods described below. The fund's purpose in writing covered call options is to realize greater income than would be realized on portfolio securities transactions alone. However, the fund may forgo the opportunity to profit from an increase in the market price of the underlying security. A put option written by the fund would obligate the fund to purchase specified securities from the option holder at a specified price if the option is exercised at any time before the expiration date. All put options written by the fund would be covered, which means that the fund would have segregated assets with a value at least equal to the exercise price of the put option. The purpose of writing such options is to generate additional income for the fund. However, in return for the option premium, the fund accepts the risk that it may be required to purchase the underlying security at a price in excess of its market value at the time of purchase. Call and put options written by the fund will also be considered to be covered to the extent that the fund's liabilities under such options are wholly or partially offset by its rights under call and put options purchased by the fund. In addition, a written call option or put may be covered by entering into an offsetting forward contract and/or by purchasing an offsetting option or any other option which, by virtue of its exercise price or otherwise, reduces the fund's net exposure on its written option position. Writing Call and Put Options on Securities Indices. The fund may also write (sell) covered call and put options on any securities index composed of securities in which it may invest. Options on securities indices are similar to options on securities, except that the exercise of securities index options requires cash payments and does not involve the actual purchase or sale of securities. In addition, securities index options are designed to reflect price fluctuations in a group of securities or segments of the securities market rather than price fluctuations in a single security. The fund may cover call options on a securities index by owning securities whose price changes are expected to be similar to those of the underlying index, or by having an absolute and immediate right to acquire such securities without additional cash consideration (or for additional consideration if cash in 14 such amount is segregated) upon conversion or exchange of other securities in its portfolio. The fund may cover call and put options on a securities index by segregating assets with a value equal to the exercise price. Purchasing Call and Put Options. The fund would normally purchase call options in anticipation of an increase in the market value of securities of the type in which it may invest. The purchase of a call option would entitle the fund, in return for the premium paid, to purchase specified securities at a specified price during the option period. The fund would ordinarily realize a gain if, during the option period, the value of such securities exceeded the sum of the exercise price, the premium paid and transaction costs; otherwise the fund would realize either no gain or a loss on the purchase of the call option. The fund would normally purchase put options in anticipation of a decline in the market value of securities in its portfolio ("protective puts") or in securities in which it may invest. The purchase of a put option would entitle the fund, in exchange for the premium paid, to sell specified securities at a specified price during the option period. The purchase of protective puts is designed to offset or hedge against a decline in the market value of the fund's securities. Put options may also be purchased by the fund for the purpose of affirmatively benefiting from a decline in the price of securities which it does not own. The fund would ordinarily realize a gain if, during the option period, the value of the underlying securities decreased below the exercise price sufficiently to more than cover the premium and transaction costs; otherwise the fund would realize either no gain or a loss on the purchase of the put option. Gains and losses on the purchase of protective put options would tend to be offset by countervailing changes in the value of the underlying portfolio securities. The fund may terminate its obligations under an exchange-traded call or put option by purchasing an option identical to the one it has written. Obligations under over-the-counter options may be terminated only by entering into an offsetting transaction with the counterparty to such option. Such purchases are referred to as "closing purchase transactions." Risks of Trading Options. There is no assurance that a liquid secondary market on an options exchange will exist for any particular exchange-traded option, or at any particular time. If the fund is unable to effect a closing purchase transaction with respect to covered options it has written, the fund will not be able to sell the underlying securities or dispose of its segregated assets until the options expire or are exercised. Similarly, if the fund is unable to effect a closing sale transaction with respect to options it has purchased, it will have to exercise the options in order to realize any profit and will incur transaction costs upon the purchase or sale of underlying securities. Reasons for the absence of a liquid secondary market on an exchange include the following: (i) there may be insufficient trading interest in certain options; (ii) restrictions may be imposed by an exchange on opening or closing transactions or both; (iii) trading halts, suspensions or other restrictions may be imposed with respect to particular classes or series of options; (iv) unusual or unforeseen circumstances may interrupt normal operations on an exchange; (v) the facilities of an exchange or the Options Clearing Corporation (the "OCC") may not at all times be adequate to handle current trading volume; or (vi) one or more exchanges could, for economic or other reasons, decide or be compelled at some future date to discontinue the trading of options (or a particular class or series of options), in which event the secondary market on that exchange (or in that class or series of options) would cease to exist, although outstanding options on that exchange, if any, that had been issued by the OCC as a result of trades on that exchange would continue to be exercisable in accordance with their terms. The fund may purchase and sell both options that are traded on U.S. and non-U.S. exchanges and options traded over-the-counter with broker-dealers who make markets in these options. The ability to terminate 15 over-the-counter options is more limited than with exchange-traded options and may involve the risk that broker-dealers participating in such transactions will not fulfill their obligations. Until such time as the staff of the SEC changes its position, the fund will treat purchased over-the-counter options and all assets used to cover written over-the-counter options as illiquid securities, except that with respect to options written with primary dealers in U.S. government securities pursuant to an agreement requiring a closing purchase transaction at a formula price, the amount of illiquid securities may be calculated with reference to the formula. Transactions by the fund in options on securities and indices will be subject to limitations established by each of the exchanges, boards of trade or other trading facilities governing the maximum number of options in each class which may be written or purchased by a single investor or group of investors acting in concert. Thus, the number of options which the fund may write or purchase may be affected by options written or purchased by other investment advisory clients of Pioneer. An exchange, board of trade or other trading facility may order the liquidations of positions found to be in excess of these limits, and it may impose certain other sanctions. The writing and purchase of options is a highly specialized activity which involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. The successful use of protective puts for hedging purposes depends in part on the ability of Pioneer to predict future price fluctuations and the degree of correlation between the options and securities markets. The hours of trading for options may not conform to the hours during which the underlying securities are traded. To the extent that the options markets close before the markets for the underlying securities, significant price movements can take place in the underlying markets that cannot be reflected in the options markets. In addition to the risks of imperfect correlation between the fund's portfolio and the index underlying the option, the purchase of securities index options involves the risk that the premium and transaction costs paid by the fund in purchasing an option will be lost. This could occur as a result of unanticipated movements in the price of the securities comprising the securities index on which the option is based. Futures Contracts and Options on Futures Contracts To hedge against changes in securities prices or currency exchange rates or to seek to increase total return, the fund may purchase and sell various kinds of futures contracts, and purchase and write (sell) call and put options on any of such futures contracts. The fund may also enter into closing purchase and sale transactions with respect to any of such contracts and options. The futures contracts may be based on various securities (such as U.S. government securities), securities indices, foreign currencies and other financial instruments and indices. The fund will engage in futures and related options transactions for bona fide hedging and non-hedging purposes as described below. All futures contracts entered into by the fund are traded on U.S. exchanges or boards of trade that are licensed and regulated by the Commodity Futures Trading Commission (the "CFTC") or on non-U.S. exchanges. Futures Contracts. A futures contract may generally be described as an agreement between two parties to buy and sell particular financial instruments for an agreed price during a designated month (or to deliver the final cash settlement price, in the case of a contract relating to an index or otherwise not calling for physical delivery at the end of trading in the contract). When interest rates are rising or securities prices are falling, the fund can seek to offset a decline in the value of its current portfolio securities through the sale of futures contracts. When interest rates are falling 16 or securities prices are rising, the fund, through the purchase of futures contracts, can attempt to secure better rates or prices than might later be available in the market when it effects anticipated purchases. Similarly, the fund can sell futures contracts on a specified currency to protect against a decline in the value of such currency and a decline in the value of its portfolio securities which are denominated in such currency. The fund can purchase futures contracts on a foreign currency to establish the price in U.S. dollars of a security denominated in such currency that the fund has acquired or expects to acquire. Positions taken in the futures markets are not normally held to maturity but are instead liquidated through offsetting transactions which may result in a profit or a loss. While futures contracts on securities or currency will usually be liquidated in this manner, the fund may instead make, or take, delivery of the underlying securities or currency whenever it appears economically advantageous to do so. A clearing corporation associated with the exchange on which futures on securities or currency are traded guarantees that, if still open, the sale or purchase will be performed on the settlement date. Hedging Strategies. Hedging, by use of futures contracts, seeks to establish with more certainty the effective price, rate of return and currency exchange rate on portfolio securities and securities that the fund owns or proposes to acquire. The fund may, for example, take a "short" position in the futures market by selling futures contracts in order to hedge against an anticipated rise in interest rates or a decline in market prices or foreign currency rates that would adversely affect the value of the fund's portfolio securities. Such futures contracts may include contracts for the future delivery of securities held by the fund or securities with characteristics similar to those of the fund's portfolio securities. Similarly, the fund may sell futures contracts in a foreign currency in which its portfolio securities are denominated or in one currency to hedge against fluctuations in the value of securities denominated in a different currency if there is an established historical pattern of correlation between the two currencies. If, in the opinion of Pioneer, there is a sufficient degree of correlation between price trends for the fund's portfolio securities and futures contracts based on other financial instruments, securities indices or other indices, the fund may also enter into such futures contracts as part of its hedging strategies. Although under some circumstances prices of securities in the fund's portfolio may be more or less volatile than prices of such futures contracts, Pioneer will attempt to estimate the extent of this volatility difference based on historical patterns and compensate for any such differential by having the fund enter into a greater or lesser number of futures contracts or by attempting to achieve only a partial hedge against price changes affecting the fund's portfolio securities. When hedging of this character is successful, any depreciation in the value of portfolio securities will be substantially offset by appreciation in the value of the futures position. On the other hand, any unanticipated appreciation in the value of the fund's portfolio securities would be substantially offset by a decline in the value of the futures position. On other occasions, the fund may take a "long" position by purchasing futures contracts. This may be done, for example, when the fund anticipates the subsequent purchase of particular securities when it has the necessary cash, but expects the prices or currency exchange rates then available in the applicable market to be less favorable than prices or rates that are currently available. Options on Futures Contracts. The acquisition of put and call options on futures contracts will give the fund the right (but not the obligation) for a specified price to sell or to purchase, respectively, the underlying futures contract at any time during the option period. As the purchaser of an option on a futures contract, the fund obtains the benefit of the futures position if prices move in a favorable direction but limits its risk of loss in the event of an unfavorable price movement to the loss of the premium and transaction costs. The writing of a call option on a futures contract generates a premium which may partially offset a decline in the value of the fund's assets. By writing a call option, the fund becomes obligated, in 17 exchange for the premium, to sell a futures contract (if the option is exercised), which may have a value higher than the exercise price. Conversely, the writing of a put option on a futures contract generates a premium which may partially offset an increase in the price of securities that the fund intends to purchase. However, the fund becomes obligated to purchase a futures contract (if the option is exercised) which may have a value lower than the exercise price. Thus, the loss incurred by the fund in writing options on futures is potentially unlimited and may exceed the amount of the premium received. The fund will incur transaction costs in connection with the writing of options on futures. The holder or writer of an option on a futures contract may terminate its position by selling or purchasing an offsetting option on the same series. There is no guarantee that such closing transactions can be effected. The fund's ability to establish and close out positions on such options will be subject to the development and maintenance of a liquid market. Other Considerations. The fund will engage in futures and related options transactions only in accordance with CFTC regulations which permit principals of an investment company registered under the 1940 Act to engage in such transactions without registering as commodity pool operators. The fund will engage in transactions in futures contracts and related options only to the extent such transactions are consistent with the requirements of the Code for maintaining its qualification as a regulated investment company for U.S. federal income tax purposes. Futures contracts and related options involve brokerage costs, require margin deposits and, in the case of contracts and options obligating the fund to purchase securities or currencies, require the fund to segregate assets to cover such contracts and options. While transactions in futures contracts and options on futures may reduce certain risks, such transactions themselves entail certain other risks. Thus, while the fund may benefit from the use of futures and options on futures, unanticipated changes in interest rates, securities prices or currency exchange rates may result in a poorer overall performance for the fund than if it had not entered into any futures contracts or options transactions. In the event of an imperfect correlation between a futures position and a portfolio position which is intended to be protected, the desired protection may not be obtained and the fund may be exposed to risk of loss. It is not possible to hedge fully or perfectly against the effect of currency fluctuations on the value of non-U.S. securities because currency movements impact the value of different securities in differing degrees. Warrants and Stock Purchase Rights The fund may invest in warrants, which are securities permitting, but not obligating, their holder to subscribe for other securities. Warrants do not carry with them the right to dividends or voting rights with respect to the securities that they entitle their holders to purchase, and they do not represent any rights in the assets of the issuer. The fund may also invest in stock purchase rights. Stock purchase rights are instruments, frequently distributed to an issuer's shareholders as a dividend, that entitle the holder to purchase a specific number of shares of common stock on a specific date or during a specific period of time. The exercise price on the rights is normally at a discount from market value of the common stock at the time of distribution. The rights do not carry with them the right to dividends or to vote and may or may not be transferable. Stock purchase rights are frequently used outside of the United States as a means of raising additional capital from an issuer's current shareholders. 18 As a result, an investment in warrants or stock purchase rights may be considered more speculative than certain other types of investments. In addition, the value of a warrant or a stock purchase right does not necessarily change with the value of the underlying securities, and warrants and stock purchase rights expire worthless if they are not exercised on or prior to their expiration date. Preferred Shares The fund may invest in preferred shares of beneficial interest of trust instruments. Preferred shares are equity securities, but they have many characteristics of fixed income securities, such as a fixed dividend payment rate and/or a liquidity preference over the issuer's common shares. However, because preferred shares are equity securities, they may be more susceptible to risks traditionally associated with equity investments than the fund's fixed income securities. Lending of Portfolio Securities The fund may lend portfolio securities to registered broker-dealers or other institutional investors deemed by Pioneer to be of good standing under agreements which require that the loans be secured continuously by collateral in cash, cash equivalents or U.S. Treasury bills maintained on a current basis at an amount at least equal to the market value of the securities loaned. The fund continues to receive the equivalent of the interest or dividends paid by the issuer on the securities loaned as well as the benefit of an increase and the detriment of any decrease in the market value of the securities loaned and would also receive compensation based on investment of the collateral. The fund may pay administrative and custodial fees in connection with loans of securities and may pay a portion of the income or fee earned thereon to the borrower, lending agent or other intermediary. The fund would not, however, have the right to vote any securities having voting rights during the existence of the loan, but would call the loan in anticipation of an important vote to be taken among holders of the securities or of the giving or withholding of consent on a material matter affecting the investment. As with other extensions of credit, there are risks of delay in recovery or even loss of rights in the collateral should the borrower of the securities fail financially. The fund will lend portfolio securities only to firms that have been approved in advance by the Board of Trustees, which will monitor the creditworthiness of any such firms. At no time would the value of the securities loaned exceed 33 1/3% of the value of the fund's total assets. Disclosure of Portfolio Holdings The fund's Board of Trustees has adopted policies and procedures relating to disclosure of the fund's portfolio securities. These policies and procedures are designed to provide a framework for disclosing information regarding portfolio holdings, portfolio composition or other portfolio characteristics consistent with applicable regulations of the federal securities laws and general principles of fiduciary duty relating to fund shareholders. While Pioneer may manage other funds and accounts that have substantially similar investment strategies, these policies and procedures only relate to the disclosure of portfolio information of registered management investment companies. Generally, Pioneer will make the fund's portfolio information available to the public on a monthly basis with an appropriate delay based upon the nature of the information disclosed. Pioneer normally will publish the fund's full portfolio holdings thirty (30) days after the end of each month. Such information shall be made available on the fund's website (www.pioneerinvestments.com) and may be sent to rating agencies, reporting/ news services and financial intermediaries, upon request. In addition, Pioneer generally makes publicly available information regarding the fund's top ten holdings (including the 19 percentage of the fund's assets represented by each security), the percentage breakdown of the fund's investments by country, sector and industry, various volatility measures (such as beta, standard deviation, etc.), market capitalization ranges and other portfolio characteristics (such as alpha, average P/E ratio, etc.) three (3) business days after the end of each month. Pioneer may provide the fund's full portfolio holdings or other information to certain entities prior to the date such information is made public, provided that certain conditions are met. The entities to which such disclosure may be made as of the date of this statement of additional information are rating agencies, plan sponsors, prospective separate account clients and other financial intermediaries (i.e., organizations evaluating the fund for purposes of investment by their clients, such as broker-dealers, investment advisers, banks, insurance companies, financial planning firms, plan sponsors, plan administrators, shareholder servicing organizations and pension consultants). As of the date of this statement of additional information, Pioneer had not provided the fund's portfolio holdings information to any entity prior to the date such information was made public. The third party must agree to a limited use of that information which does not conflict with the interests of the fund's shareholders, to use the information only for that authorized purpose, to keep such information confidential, and not to trade on such information. The Board of Trustees considered the disclosure of portfolio holdings information to these categories of entities to be consistent with the best interests of shareholders in light of the agreement to maintain the confidentiality of such information and only to use such information for the limited and approved purposes. Pioneer's compliance department, the local head of investment management and the global chief investment officer may, but only acting jointly, grant exemptions to this policy. Exemptions may be granted only if these persons determine that providing such information is consistent with the interests of shareholders and the third party agrees to limit the use of such information only for the authorized purpose, to keep such information confidential, and not to trade on such information. Although the Board will periodically be informed of exemptions granted, granting exemptions entails the risk that portfolio holdings information may be provided to entities that use the information in a manner inconsistent with their obligations and the best interests of the fund. Compliance with the fund's portfolio holdings disclosure policy is subject to periodic review by the Board of Trustees, including a review of any potential conflicts of interest in the disclosures made by Pioneer in accordance with the policy or the exceptions permitted under the policy. Any change to the policy to expand the categories of entities to which portfolio holdings may be disclosed or an increase in the purposes for which such disclosure may be made would be subject to approval by the Board of Trustees and, reflected, if material, in a supplement to the fund's statement of additional information. The fund's portfolio holdings disclosure policy is not intended to prevent the disclosure of any and all portfolio information to the fund's service providers who generally need access to such information in the performance of their contractual duties and responsibilities, such as Pioneer, the fund's custodian, fund accounting agent, principal underwriter, investment sub-adviser, if any, independent registered public accounting firm or counsel. In approving the policy, the Board of Trustees considered that the service providers are subject to duties of confidentiality arising under law or contract that provide an adequate safeguard for such information. None of Pioneer, the fund or any other party receive any compensation or other consideration from any arrangement pertaining to the release of the fund's portfolio holdings information. In addition, the fund makes its portfolio holdings available semi-annually in shareholder reports filed on Form N-CSR and after the first and third fiscal quarters in regulatory filings on Form N-Q. These shareholder reports and regulatory filings are filed with the SEC, as required by the federal securities laws, and are generally available within seventy (70) days after the end of the fund's fiscal quarter. 20 Investment Restrictions Fundamental Investment Restrictions. The fund has adopted certain fundamental investment restrictions which may not be changed without the affirmative vote of the holders of a "majority of the outstanding voting securities" (as defined in the 1940 Act) of the fund. Statements in italics are not part of the restriction. For this purpose, a majority of the outstanding shares of the fund means the vote of the lesser of: 1. 67% or more of the shares represented at a meeting, if the holders of more than 50% of the outstanding shares are present in person or by proxy, or 2. more than 50% of the outstanding shares of the fund. The fund may not: (1) Issue senior securities, except as permitted by the fund's borrowing, lending and commodity restrictions and, for purposes of this restriction, the issuance of shares of beneficial interest in multiple classes or series, the purchase or sale of options, futures contracts and options on futures contracts, forward commitments, forward foreign exchange contracts, repurchase agreements, fully covered reverse repurchase agreements, dollar rolls, swaps and any other financial transaction entered into pursuant to the fund's investment policies as described in the prospectuses and the statements of additional information and in accordance with applicable SEC pronouncements, as well as the pledge, mortgage or hypothecation of the fund's assets within the meaning of the fundamental investment restriction regarding pledging, are not deemed to be senior securities. (2) Borrow money, except from banks as a temporary measure to facilitate the meeting of redemption requests or for extraordinary emergency purposes and except pursuant to reverse repurchase agreements and dollar rolls and then only in amounts not to exceed 33 1/3 of the fund's total assets (including the amount borrowed) taken at market value. The fund will not use leverage to attempt to increase income. In the opinion of the SEC, the fund's limitation on borrowing includes any pledge, mortgage or hypothecation of its assets. (3) Guarantee the securities of any other company, or mortgage, pledge, hypothecate or assign or otherwise encumber as security for indebtedness its securities or receivables in an amount exceeding the amount of the borrowing thereby secured. (4) Act as an underwriter, except as it may be deemed to be an underwriter in a sale of restricted securities held in its portfolio. (5) Invest in real estate, commodities or commodity contracts, except that the fund may invest in securities of issuers that invest in real estate or interests therein, securities that are secured by real estate or interests therein, financial futures contracts and related options and in any other financial instruments which may be deemed to be commodities or commodity contracts in which the fund is not prohibited from investing by the Commodity Exchange Act and the rules and regulations thereunder. (6) Make loans, except by the purchase of debt obligations in which the fund may invest consistent with its investment policies, by entering into repurchase agreements or through the lending of portfolio securities, in each case only to the extent permitted by the prospectuses and the statements of additional information. 21 (7) With respect to 75% of its total assets, purchase securities of an issuer (other than the U.S. government, its agencies or instrumentalities), if (a) such purchase would cause more than 5% of the fund's total assets, taken at market value, to be invested in the securities of such issuer, or (b) such purchase would at the time result in more than 10% of the outstanding voting securities of such issuer being held by the fund. (8) Concentrate its investments in securities of companies in any particular industry. The fund's policy does not apply to investments in U.S. government securities. In the opinion of the SEC, investments are concentrated in a particular industry if such investments aggregate 25% or more of the fund's total assets. When identifying industries for purposes of its concentration policy, the fund will rely upon available industry classifications. As of the date of this statement of additional information, the fund relied on MSCI Global Industry Classification Standard (GICS) classifications. Non-Fundamental Investment Restrictions. The following restrictions have been designated as non-fundamental and all restrictions not deemed fundamental, including those set forth below, may be changed by a vote of the fund's Board of Trustees without approval of shareholders. The fund may not: (a) Purchase securities during the current fiscal year while borrowings are in excess of 5% of the fund's total assets. (b) Engage in mortgaging, hypothecating or pledging of its assets except in connection with any borrowing permitted under fundamental investment restriction (2); thus the fund's borrowings involving mortgaging, hypothecating or pledging of its assets will not exceed 33 1/3% of its total assets (including the amount borrowed), notwithstanding any temporary borrowings not in excess of 5% of its total assets. (c) Invest in any investment company in reliance on Section 12(d)(1)(F) of the 1940 Act, which would allow the fund to invest in other investment companies, or in reliance on Section 12(d)(1)(G) of the 1940 Act, which would allow the fund to invest in other Pioneer funds, in each case without being subject to the limitations discussed above under "Other Investment Companies" so long as another investment company invests in the fund in reliance on Section 12(d)(1)(G). The fund has adopted this non-fundamental policy in order that the fund may be a permitted investment to the series of Pioneer Ibbotson Asset Allocation Series, which invest all of their assets in other investment companies. If the series of Pioneer Ibbotson Asset Allocation Series do not invest in the fund, then this non-fundamental restriction will not apply. 3.

Board Committees During the most recent fiscal year, the Board of Trustees held 11 meetings. Each Trustee attended at least 75% of such meetings. The Board of Trustees has an Audit Committee, an Independent Trustees Committee, a Nominating Committee, a Valuation Committee and a Policy Administration Committee. Committee members are as follows: Audit David R. Bock, Margaret B. W. Graham, Marguerite A. Piret (Chair) and Stephen K. West Independent Trustees David R. Bock, Mary K. Bush, Margaret B.W. Graham (Chair), Thomas J. Perna, Marguerite A. Piret, Stephen K. West and John Winthrop Nominating Mary K. Bush, Marguerite A. Piret and John Winthrop (Chair) Valuation David R. Bock, Margaret B. W. Graham, Marguerite A. Piret (Chair) and Stephen K. West Policy Administration Mary K. Bush (Chair), Thomas J. Perna and John Winthrop During the most recent fiscal year, the Audit, Independent Trustees, Nominating, Valuation, and Policy Administration Committees held 16, 13, 3, 4 and 9 meetings, respectively. The Board of Trustees has adopted a charter for the Audit Committee. In accordance with its charter, the purposes of the Audit Committee are to: o act as a liaison between the fund's independent registered public accounting firm and the full Board of Trustees of the fund; o discuss with the fund's independent registered public accounting firm their judgments about the quality of the fund's accounting principles and underlying estimates as applied in the fund's financial reporting; o review and assess the renewal materials of all related party contracts and agreements, including management advisory agreements, underwriting contracts, administration agreements, distribution contracts, and transfer agency contracts, among any other instruments and agreements that may be appropriate from time to time; 28 o review and approve insurance coverage and allocations of premiums between the management and the fund and among the Pioneer Funds; o review and approve expenses under the administration agreement between Pioneer and the fund and allocations of such expenses among the Pioneer Funds; and o receive on a periodic basis a formal written statement delineating all relationships between the independent registered public accounting firm and the fund or Pioneer; to actively engage in a dialogue with the independent registered public accounting firm with respect to any disclosed relationships or services that may impact the objectivity and independence of the firm; and to recommend that the Trustees take appropriate action in response to the independent registered public accounting firm's report to satisfy itself of the firm's independence. The Nominating Committee reviews the qualifications of any candidate recommended by the Independent Trustees to serve as an Independent Trustee and makes a recommendation regarding that person's qualifications. The Committee does not accept nominations from shareholders. The Valuation Committee reviews the valuation assigned to certain securities by Pioneer in accordance with the fund's valuation procedures. The Policy Administration Committee reviews the implementation of certain of the fund's administrative policies and procedures. The Independent Trustees Committee reviews the fund's management contract and other related party contracts annually and is also responsible for any other action required to be taken, under the 1940 Act, by the Independent Trustees acting alone. The Agreement and Declaration of Trust provides that the Trust will indemnify the Trustees and officers against liabilities and expenses incurred in connection with any litigation in which they may be involved because of their offices with the Trust, unless it is determined in the manner specified in the Agreement and Declaration of Trust that they have not acted in good faith in the reasonable belief that their actions were in the best interests of the Trust or the fund or that such indemnification would relieve any officer or Trustee of any liability to the Trust or the fund or its shareholders by reason of willful misfeasance, bad faith, gross negligence or reckless disregard of his or her duties. Compensation of Officers and Trustees The fund pays no salaries or compensation to any of its officers. The Pioneer Funds, including the fund, compensate their Trustees. The Independent Trustees review and set their compensation annually, taking into consideration the committee and other responsibilities assigned to specific Trustees. The table under "Annual Fees, Expense and Other Information-Compensation of Officers and Trustees" sets forth the compensation paid to each of the Trustees. The compensation paid to the Trustees is then allocated among the funds as follows: o each fund with assets less than $250 million pays each Trustee who is not affiliated with PIM-USA, Pioneer, PFD, PIMSS or UniCredito Italiano (i.e., Independent Trustees) an annual fee of $1,000. o the remaining compensation of the Independent Trustees is allocated to each fund with assets greater than $250 million based on the fund's net assets. 29 o the Interested Trustees receive an annual fee of $500 from each fund, except in the case of funds with net assets of $50 million or less, which pay each Interested Trustee an annual fee of $200. Pioneer reimburses the funds for the fees paid to the Interested Trustees. See "Compensation of Officers and Trustees" in "Annual Fee, Expense and Other Information." Sales Loads. The fund offers its shares to Trustees and officers of the fund and employees of Pioneer and its affiliates without a sales charge in order to encourage investment in the fund by individuals who are responsible for its management and because the sales to such persons do not entail any sales effort by the fund, brokers or other intermediaries. Other Information Material Relationships of the Independent Trustees. For purposes of the statements below: o the immediate family members of any person are their spouse, children in the person's household (including step and adoptive children) and any dependent of the person. o an entity in a control relationship means any person who controls, is controlled by or is under common control with the named person. For example, UniCredito Italiano is an entity that is in a control relationship with Pioneer. o a related fund is a registered investment company or an entity exempt from the definition of an investment company pursuant to Sections 3(c)(1) or 3(c)(7) of the 1940 Act, for which Pioneer or any of its affiliates act as investment adviser or for which PFD or any of its affiliates act as principal underwriter. For example, the fund's related funds include all of the Pioneer Funds and any non-U.S. funds managed by Pioneer or its affiliates. As of December 31, 2006, none of the Independent Trustees, nor any of their immediate family members, beneficially owned any securities issued by Pioneer, UniCredito Italiano or any other entity in a control relationship to Pioneer or PFD. During the calendar years 2005 and 2006, none of the Independent Trustees, nor any of their immediate family members, had any direct or indirect interest (the value of which exceeded $120,000), whether by contract, arrangement or otherwise, in Pioneer, UniCredito Italiano, or any other entity in a control relationship to Pioneer or PFD. During the calendar years 2005 and 2006, none of the Independent Trustees, nor any of their immediate family members, had an interest in a transaction or a series of transactions in which the aggregate amount involved exceeded $120,000 and to which any of the following were a party (each a "fund related party"): o the fund o an officer of the fund o a related fund o an officer of any related fund o Pioneer o PFD o an officer of Pioneer or PFD o any affiliate of Pioneer or PFD o an officer of any such affiliate During the calendar years 2005 and 2006, none of the Independent Trustees, nor any of their immediate 30 family members, had any relationship (the value of which exceeded $120,000) with any fund related party, including, but not limited to, relationships arising out of (i) the payment for property and services, (ii) the provision of legal services, (iii) the provision of investment banking services (other than as a member of the underwriting syndicate) or (iv) the provision of consulting services, except that Mr. West, an Independent Trustee, is Senior Counsel to Sullivan & Cromwell and acts as counsel to the Independent Trustees and the Independent Trustees of the other Pioneer Funds. The aggregate compensation paid to Sullivan & Cromwell by the fund and the other Pioneer Funds was approximately $173,353 and $287,452.56 in each of 2005 and 2006, respectively. During the calendar years 2005 and 2006, none of the Independent Trustees, nor any of their immediate family members, served as a member of a board of directors on which an officer of any of the following entities also serves as a director: o Pioneer o PFD o UniCredito Italiano o any other entity in a control relationship with Pioneer or PFD None of the fund's Trustees or officers has any arrangement with any other person pursuant to which that Trustee or officer serves on the Board of Trustees. During the calendar years 2005 and 2006, none of the Independent Trustees, nor any of their immediate family members, had any position, including as an officer, employee, director or partner, with any of the following: o the fund o any related fund o Pioneer o PFD o any affiliated person of the fund, Pioneer or PFD o UniCredito Italiano o any other entity in a control relationship to the fund, Pioneer or PFD Share Ownership. See "Annual Fee, Expense and Other Information" for annual information on the ownership of fund shares by the Trustees, the fund's officers and owners in excess of 5% of any class of shares of the fund and a table indicating the value of shares that each Trustee beneficially owns in the fund and in all the Pioneer Funds. Code of Ethics. The fund's Board of Trustees approved a code of ethics under Rule 17j-1 under the 1940 Act that covers the fund, Pioneer and certain of Pioneer's affiliates. The code of ethics establishes procedures for personal investing and restricts certain transactions. Employees subject to the code of ethics may invest in securities for their personal investment accounts, including securities that may be purchased or held by the fund. Proxy Voting Policies. Information regarding how the funds voted proxies relating to portfolio securities during the most recent 12-month period ended June 30 is publicly available to shareowners without charge at http://www.pioneerinvestments.com and on the SEC's website at http://www.sec.gov. The fund's "Proxy Voting Policies and Procedures" are attached as "Appendix B". 31 4. INVESTMENT ADVISER The fund has contracted with Pioneer to act as its investment adviser. Pioneer is an indirect, wholly owned subsidiary of UniCredito Italiano. Certain Trustees or officers of the fund are also directors and/or officers of certain of UniCredito Italiano's subsidiaries (see management biographies above). Pioneer has entered into an agreement with its affiliate, Pioneer Investment Management Limited ("PIML"), pursuant to which PIML provides certain services and personnel to Pioneer. As the fund's investment adviser, Pioneer provides the fund with investment research, advice and supervision and furnishes an investment program for the fund consistent with the fund's investment objective and policies, subject to the supervision of the fund's Trustees. Pioneer determines what portfolio securities will be purchased or sold, arranges for the placing of orders for the purchase or sale of portfolio securities, selects brokers or dealers to place those orders, maintains books and records with respect to the fund's securities transactions, and reports to the Trustees on the fund's investments and performance. Under the terms of its management contract with the fund, Pioneer pays all the operating expenses, including executive salaries and the rental of office space, relating to its services for the fund, with the exception of the following, which are paid by the fund: (a) charges and expenses for fund accounting, pricing and appraisal services and related overhead, including, to the extent such services are performed by personnel of Pioneer or its affiliates, office space and facilities and personnel compensation, training and benefits; (b) the charges and expenses of auditors; (c) the charges and expenses of any custodian, transfer agent, plan agent, dividend disbursing agent and registrar appointed by the fund; (d) issue and transfer taxes chargeable to the fund in connection with securities transactions to which the fund is a party; (e) insurance premiums, interest charges, dues and fees for membership in trade associations and all taxes and corporate fees payable by the fund to federal, state or other governmental agencies; (f) fees and expenses involved in registering and maintaining registrations of the fund and/or its shares with federal regulatory agencies, state or blue sky securities agencies and foreign jurisdictions, including the preparation of prospectuses and statements of additional information for filing with such regulatory authorities; (g) all expenses of shareholders' and Trustees' meetings and of preparing, printing and distributing prospectuses, notices, proxy statements and all reports to shareholders and to governmental agencies; (h) charges and expenses of legal counsel to the fund and the Trustees; (i) any distribution fees paid by the fund in accordance with Rule 12b-1 promulgated by the SEC pursuant to the 1940 Act; (j) compensation of those Trustees of the fund who are not affiliated with or interested persons of Pioneer, the fund (other than as Trustees), PIM-USA or PFD; (k) the cost of preparing and printing share certificates; and (l) interest on borrowed money, if any. In addition, the fund shall pay all brokers' and underwriting commissions chargeable to the fund in connection with securities transactions to which the fund is a party. The Trustees' approval of and the terms, continuance and termination of the management contract are governed by the 1940 Act and the Investment Advisers Act of 1940, as applicable. Pursuant to the management contract, Pioneer will not be liable for any error of judgment or mistake of law or for any loss sustained by reason of the adoption of any investment policy or the purchase, sale or retention of any securities on the recommendation of Pioneer. Pioneer, however, is not protected against liability by reason of willful misfeasance, bad faith or gross negligence in the performance of its duties or by reason of its reckless disregard of its obligations and duties under the management contract. Advisory Fee. As compensation for its management services and expenses incurred, the fund pays Pioneer a fee at the annual rate of 0.75% of the fund's average daily net assets. This fee is computed and accrued daily and paid monthly. See the table in "Annual Fee, Expense and Other Information" for the management fees paid to Pioneer during recently completed fiscal years. 32 Administration Agreement. The fund has entered into an administration agreement with Pioneer pursuant to which certain accounting, administration and legal services are performed by Pioneer and pursuant to which Pioneer receives a fee at the annual rate of 0.0225% of the fund's average daily net assets. See "Annual Fee, Expense and Other Information" for fees the fund paid to Pioneer for administration and related services. Expense Limit. Pioneer has contractually agreed to limit ordinary operating expenses to the extent required to reduce fund expenses for Class A shares to 1.25% of average daily net assets and for Class C shares to 2.15% of average daily net assets. These expense limitations are in effect through May 1, 2009 for Class A shares and through May 1, 2008 for Class C shares. Ordinary operating expenses include all fund expenses other than extraordinary expenses, sucs as litigation, taxes and brokerage commissions. Pioneer expects to continue its limitations of expenses unless the expense limit agreement with the fund is terminated pursuant to the terms of the expense limit agreement. However, there can be no assurance that Pioneer will extend the expense limitation beyond May 1, 2009 for Class A shares and beyond May 1, 2008 for Class C shares. The fund may terminate the expense limit agreement at any time; provided, however, that the Board of Trustees would not take such action unless it determined termination of the agreement to be in the best interests of the fund and its shareholders. Potential Conflicts of Interest. The fund is managed by Pioneer which also serves as investment adviser to other Pioneer mutual funds and other accounts with investment objectives identical or similar to those of the fund. Securities frequently meet the investment objectives of the fund, the other Pioneer mutual funds and such other accounts. In such cases, the decision to recommend a purchase to one fund or account rather than another is based on a number of factors. The determining factors in most cases are the amount of securities of the issuer then outstanding, the value of those securities and the market for them. Other factors considered in the investment recommendations include other investments which each fund or account presently has in a particular industry and the availability of investment funds in each fund or account. It is possible that at times identical securities will be held by more than one fund and/or account. However, positions in the same issue may vary and the length of time that any fund or account may choose to hold its investment in the same issue may likewise vary. To the extent that more than one of the Pioneer mutual funds or a private account managed by Pioneer seeks to acquire the same security at about the same time, the fund may not be able to acquire as large a position in such security as it desires or it may have to pay a higher price for the security. Similarly, the fund may not be able to obtain as large an execution of an order to sell or as high a price for any particular portfolio security if Pioneer decides to sell on behalf of another account the same portfolio security at the same time. On the other hand, if the same securities are bought or sold at the same time by more than one fund or account, the resulting participation in volume transactions could produce better executions for the fund. In the event more than one account purchases or sells the same security on a given date, the purchases and sales will normally be made as nearly as practicable on a pro rata basis in proportion to the amounts desired to be purchased or sold by each account. Although the other Pioneer mutual funds may have the same or similar investment objectives and policies as the fund, their portfolios do not generally consist of the same investments as the fund or each other, and their performance results are likely to differ from those of the fund. Personal Securities Transactions. The fund, Pioneer, and PFD have adopted a code of ethics under Rule 17j-1 under the 1940 Act which is applicable to officers, trustees/directors and designated employees of Pioneer and PIML. The code permits such persons to engage in personal securities transactions for their own accounts, including securities that may be purchased or held by the fund, and is designed to prescribe 33 means reasonably necessary to prevent conflicts of interest from arising in connection with personal securities transactions. The code is on public file with and available from the SEC. 5. PRINCIPAL UNDERWRITER AND DISTRIBUTION PLAN Principal Underwriter PFD, 60 State Street, Boston, Massachusetts 02109, is the principal underwriter for the fund in connection with the continuous offering of its shares. PFD is an indirect wholly owned subsidiary of PIM-USA. The fund entered into an underwriting agreement with PFD which provides that PFD will bear expenses for the distribution of the fund's shares, except for expenses incurred by PFD for which it is reimbursed or compensated by the fund under the distribution plan (discussed below). PFD bears all expenses it incurs in providing services under the underwriting agreement. Such expenses include compensation to its employees and representatives and to securities dealers for distribution-related services performed for the fund. PFD also pays certain expenses in connection with the distribution of the fund's shares, including the cost of preparing, printing and distributing advertising or promotional materials, and the cost of printing and distributing prospectuses and supplements to prospective shareholders. The fund bears the cost of registering its shares under federal and state securities law and the laws of certain non-U.S. countries. Under the underwriting agreement, PFD will use its best efforts in rendering services to the fund. See "Sales Charges" for the schedule of initial sales charge reallowed to dealers as a percentage of the offering price of the fund's applicable share class. See the tables in "Annual Fee, Expense and Other Information" for commissions retained by PFD and reallowed to dealers in connection with PFD's offering of the fund's applicable share class during recently completed fiscal years. The fund will not generally issue fund shares for consideration other than cash. At the fund's sole discretion, however, it may issue fund shares for consideration other than cash in connection with a bona fide reorganization, statutory merger or other acquisition of portfolio securities. It is the fund's general practice to repurchase its shares of beneficial interest for cash consideration in any amount; however, the redemption price of shares of the fund may, at Pioneer's discretion, be paid in portfolio securities. The fund has elected to be governed by Rule 18f-1 under the 1940 Act pursuant to which the fund is obligated to redeem shares solely in cash up to the lesser of $250,000 or 1% of the fund's net asset value during any 90-day period for any one shareholder. Should the amount of redemptions by any shareholder exceed such limitation, the fund will have the option of redeeming the excess in cash or portfolio securities. In the latter case, the securities are taken at their value employed in determining the fund's net asset value. You may incur additional costs, such as brokerage fees and taxes, and risks, including a decline in the value of the securities you receive, if the fund makes an in-kind distribution. The selection of such securities will be made in such manner as the Board of Trustees deems fair and reasonable; however, the fund will not distribute illiquid securities in kind. Distribution Plan The fund has adopted a plan of distribution pursuant to Rule 12b-1 under the 1940 Act with respect to its Class A shares (the "Class A Plan") and a plan of distribution with respect to its Class C shares (the "Class C Plan") (together, the "Plans"), pursuant to which certain distribution and service fees are paid to 34 PFD. Because of the Plans, long-term shareholders may pay more than the economic equivalent of the maximum sales charge permitted by the National Association of Securities Dealers, Inc. (the "NASD") regarding investment companies. The Class A Plan is a reimbursement plan, and distribution expenses of PFD are expected to substantially exceed the distribution fees paid by the fund in a given year. The Class C Plan is a compensation plan, which means that the amount of payments under the Class C Plan are not linked to PFD's expenditures and, consequently, PFD can make a profit under the Class C Plan. Class A Plan. Pursuant to the Class A Plan the fund reimburses PFD for its actual expenditures to finance any activity primarily intended to result in the sale of Class A shares or to provide services to holders of Class A shares, provided the categories of expenses for which reimbursement is made are approved by the Board of Trustees. The Board of Trustees has approved the following categories of expenses that may be reimbursed under the Class A Plan: (i) a service fee to be paid to qualified broker-dealers in an amount not to exceed 0.25% per annum of the fund's daily net assets attributable to Class A shares; (ii) reimbursement to PFD for its expenditures for broker-dealer commissions and employee compensation on certain sales of the fund's Class A shares with no initial sales charge; and (iii) reimbursement to PFD for expenses incurred in providing services to Class A shareholders and supporting broker-dealers and other organizations (such as banks and trust companies) in their efforts to provide such services. The expenses of the fund pursuant to the Class A Plan are accrued daily at a rate which may not exceed the annual rate of 0.25% of the fund's average daily net assets attributable to Class A shares. The Class A Plan does not provide for the carryover of reimbursable expenses beyond 12 months from the time the fund is first invoiced for an expense. The limited carryover provision in the Class A Plan may result in an expense invoiced to the fund in one fiscal year being paid in the subsequent fiscal year and thus being treated for purposes of calculating the maximum expenditures of the fund as having been incurred in the subsequent fiscal year. In the event of termination or non-continuance of the Class A Plan, the fund has 12 months to reimburse any expense which it incurs prior to such termination or non-continuance, provided that payments by the fund during such 12-month period shall not exceed 0.25% of the fund's average daily net assets attributable to Class A shares during such period. See "Annual Fee, Expense and Other Information" for the amount, if any, of carryover of distribution expenses as of the end of the most recent calendar year. Class C Plan. Commissions on the sale of Class C shares of up to 0.75% of the amount invested in Class C shares are paid to broker-dealers who have sales agreements with PFD. PFD may also advance to dealers the first-year service fee payable under the Class C Plan at a rate up to 0.25% of the purchase price of such shares. As compensation for such advance of the service fee, PFD may retain the service fee paid by the fund with respect to such shares for the first year after purchase. The Class C Plan provides that the fund will pay PFD, as the fund's distributor for its Class C shares, a distribution fee accrued daily and paid quarterly, equal on an annual basis to 0.75% of the fund's average daily net assets attributable to Class C shares and will pay PFD a service fee equal to 0.25% of the fund's average daily net assets attributable to Class C shares. PFD will in turn pay to securities dealers that enter into a sales agreement with PFD a distribution fee and a service fee at rates of up to 0.75% and 0.25%, respectively, of the fund's average daily net assets attributable to Class C shares owned by investors for whom that securities dealer is the holder or dealer of record. The service fee is intended to be in consideration of personal services and/or account maintenance services rendered by the dealer with respect to Class C shares. PFD will advance to dealers the first-year service fee at a rate equal to 0.25% of the amount invested. As compensation therefor, PFD may retain the service fee paid by the fund with respect to such shares for the first year after purchase. Commencing in the 13th month following the purchase of Class C shares, dealers will become eligible for additional annual distribution fees and service 35 fees of up to 0.75% and 0.25%, respectively, of the net asset value of such shares. Dealers may from time to time be required to meet certain other criteria in order to receive service fees. PFD or its affiliates are entitled to retain all service fees payable under the Class C Plan for which there is no dealer of record or for which qualification standards have not been met as partial consideration for personal services and/or account maintenance services performed by PFD or its affiliates for shareholder accounts. The purpose of distribution payments to PFD under the Class C Plan is to compensate PFD for its distribution services with respect to Class C shares of the fund. PFD pays commissions to dealers as well as expenses of printing prospectuses and reports used for sales purposes, expenses with respect to the preparation and printing of sales literature and other distribution-related expenses, including, without limitation, the cost necessary to provide distribution-related services, or personnel, travel, office expenses and equipment. The Class C Plan also provides that PFD will receive all CDSCs attributable to Class C shares. When a broker-dealer sells Class C shares and elects, with PFD's approval, to waive its right to receive the commission normally paid at the time of the sale, PFD may cause all or a portion of the distribution fees described above to be paid to the broker-dealer. General In accordance with the terms of each Plan, PFD provides to the fund for review by the Trustees a quarterly written report of the amounts expended under the Plan and the purposes for which such expenditures were made. In the Trustees' quarterly review of the Plans, they will consider the continued appropriateness and the level of reimbursement or compensation the Plans provide. No interested person of the fund, nor any Trustee of the fund who is not an interested person of the fund, has any direct or indirect financial interest in the operation of the Plans except to the extent that PFD and certain of its employees may be deemed to have such an interest as a result of receiving a portion of the amounts expended under the Plans by the fund and except to the extent certain officers may have an interest in PFD's ultimate parent, UniCredito Italiano, or in UniCredito Italiano's subsidiaries. Each Plan's adoption, terms, continuance and termination are governed by Rule 12b-1 under the 1940 Act. The Board of Trustees believes that there is a reasonable likelihood that the Plans will benefit the fund and its current and future shareholders. The Plans may not be amended to increase materially the annual percentage limitation of average net assets which may be spent for the services described therein without approval of the shareholders of the fund affected thereby, and material amendments of the Plans must also be approved by the Trustees as provided in Rule 12b-1. See "Annual Fee, Expense and Other Information" for fund expenses under the Class A Plan and Class C Plan and CDSCs paid to PFD for the most recently completed fiscal year. Upon redemption, Class A shares and Class C shares may be subject to a 1% CDSC. No front-end, deferred or asset based sales charges are applicable to class Y shareholders. 6. SHAREHOLDER SERVICING/TRANSFER AGENT The fund has contracted with PIMSS, 60 State Street, Boston, Massachusetts 02109, to act as shareholder servicing and transfer agent for the fund. Under the terms of its contract with the fund, PIMSS services shareholder accounts, and its duties include: (i) processing sales, redemptions and exchanges of shares of the fund; (ii) distributing dividends 36 and capital gains associated with the fund's portfolio; and (iii) maintaining account records and responding to shareholder inquiries. PIMSS receives an annual fee of $26.60 for each shareholder account from the fund as compensation for the services described above. PIMSS is also reimbursed by the fund for its cash out-of-pocket expenditures. The fund may compensate entities which have agreed to provide certain sub-accounting services such as specific transaction processing and recordkeeping services. Any such payments by the fund would be in lieu of the per account fee which would otherwise be paid by the fund to PIMSS. 7. CUSTODIAN Brown Brothers Harriman & Co., 40 Water Street, Boston, Massachusetts 02109, is the custodian of the fund's assets. The custodian's responsibilities include safekeeping and controlling the fund's cash and securities, handling the receipt and delivery of securities, and collecting interest and dividends on the fund's investments. 8. INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM Ernst & Young LLP, 200 Clarendon Street, Boston, Massachusetts 02116, the fund's independent registered public accounting firm, provides audit services, tax return review, and assistance and consultation with respect to the preparation of filings with the SEC. 9. PORTFOLIO MANAGEMENT Additional Information About the Portfolio Manager Other Accounts Managed by the Portfolio Manager. The table below indicates, for the portfolio manager of the fund, information about the accounts other than the fund over which the portfolio manager has day-to-day investment responsibility. All information on the number of accounts and total assets in the table is as of December 31, 2006. For purposes of the table, "Other Pooled Investment Vehicles" may include investment partnerships, undertakings for collective investments in transferable securities ("UCITS") and other non-U.S. investment funds and group trusts, and "Other Accounts" may include separate accounts for institutions or individuals, insurance company general or separate accounts, pension funds and other similar institutional accounts but generally do not include the portfolio manager's personal investment accounts or those which the manager may be deemed to own beneficially under the code of ethics. Certain funds and other accounts managed by the portfolio manager may have substantially similar investment strategies.

When a portfolio manager is responsible for the management of more than one account, the potential arises for the portfolio manager to favor one account over another. The principal types of potential conflicts of interest that may arise are discussed below. For the reasons outlined below, Pioneer does not believe that any material conflicts are likely to arise out of a portfolio manager's responsibility for the management of the fund as well as one or more other accounts. Although Pioneer has adopted procedures that it believes are reasonably designed to detect and prevent violations of the federal securities laws and to mitigate the potential for conflicts of interest to affect its portfolio management decisions, there can be no assurance that all conflicts will be identified or that all procedures will be effective in mitigating the potential for such risks. Generally, the risks of such conflicts of interests are increased to the extent that a portfolio manager has a financial incentive to favor one account over another. Pioneer has structured its compensation arrangements in a manner that is intended to limit such potential for conflicts of interests. See "Compensation of Portfolio Managers" below. o A portfolio manager could favor one account over another in allocating new investment opportunities that have limited supply, such as initial public offerings and private placements. If, for example, an initial public offering that was expected to appreciate in value significantly shortly after the offering was allocated to a single account, that account may be expected to have better investment performance than other accounts that did not receive an allocation of the initial public offering. Generally, investments for which there is limited availability are allocated based upon a range of factors including available cash and consistency with the accounts' investment objectives and policies. This allocation methodology necessarily involves some subjective elements but is intended over time to treat each client in an equitable and fair manner. Generally, the investment opportunity is allocated among participating accounts on a pro rata basis. Although Pioneer believes that its practices are reasonably designed to treat each client in an equitable and fair manner, there may be instances where a fund may not participate, or may participate to a lesser degree than other clients, in the allocation of an investment opportunity. o A portfolio manager could favor one account over another in the order in which trades for the accounts are placed. If a portfolio manager determines to purchase a security for more than one account in an aggregate amount that may influence the market price of the security, accounts that purchased or sold the security first may receive a more favorable price than accounts that made subsequent transactions. The less liquid the market for the security or the greater the percentage that the proposed aggregate purchases or sales represent of average daily trading volume, the greater the potential for accounts that make subsequent purchases or sales to receive a less favorable price. When a portfolio manager intends to trade the same security on the same day for more than one account, the trades typically are "bunched," which means that the trades for the individual accounts are aggregated and each account receives the same price. There are some types of accounts as to which bunching may not be possible for contractual reasons (such as directed brokerage arrangements). Circumstances may also arise where the trader believes that bunching the orders may not result in the best possible price. Where those accounts or circumstances are involved, Pioneer will place the order in a manner intended to result in as favorable a price as possible for such client. 38 o A portfolio manager could favor an account if the portfolio manager's compensation is tied to the performance of that account to a greater degree than other accounts managed by the portfolio manager. If, for example, the portfolio manager receives a bonus based upon the performance of certain accounts relative to a benchmark while other accounts are disregarded for this purpose, the portfolio manager will have a financial incentive to seek to have the accounts that determine the portfolio manager's bonus achieve the best possible performance to the possible detriment of other accounts. Similarly, if Pioneer receives a performance-based advisory fee, the portfolio manager may favor that account, whether or not the performance of that account directly determines the portfolio manager's compensation. o A portfolio manager could favor an account if the portfolio manager has a beneficial interest in the account, in order to benefit a large client or to compensate a client that had poor returns. For example, if the portfolio manager held an interest in an investment partnership that was one of the accounts managed by the portfolio manager, the portfolio manager would have an economic incentive to favor the account in which the portfolio manager held an interest. o If the different accounts have materially and potentially conflicting investment objectives or strategies, a conflict of interest could arise. For example, if a portfolio manager purchases a security for one account and sells the same security for another account, such trading pattern may disadvantage either the account that is long or short. In making portfolio manager assignments, Pioneer seeks to avoid such potentially conflicting situations. However, where a portfolio manager is responsible for accounts with differing investment objectives and policies, it is possible that the portfolio manager will conclude that it is in the best interest of one account to sell a portfolio security while another account continues to hold or increase the holding in such security. Compensation of Portfolio Managers. Pioneer has adopted a system of compensation for portfolio managers that seeks to align the financial interests of the portfolio managers with those of shareholders of the accounts (including Pioneer funds) the portfolio managers manage, as well as with the financial performance of Pioneer. The compensation program for all Pioneer portfolio managers includes a base salary (determined by the rank and tenure of the employee) and an annual bonus program, as well as customary benefits that are offered generally to all full-time employees. Base compensation is fixed and normally reevaluated on an annual basis. Pioneer seeks to set base compensation at market rates, taking into account the experience and responsibilities of the portfolio manager. The bonus plan is intended to provide a competitive level of annual bonus compensation that is tied to the portfolio manager achieving superior investment performance and align the interests of the investment professional with those of shareholders, as well as with the financial performance of Pioneer. Any bonus under the plan is completely discretionary, with a maximum annual bonus that may be in excess of base salary. The annual bonus is based upon a combination of the following factors: o Quantitative Investment Performance. The quantitative investment performance calculation is based on pre-tax investment performance of all of the accounts managed by the portfolio manager (which includes the fund and any other accounts managed by the portfolio manager) over a one-year period (20% weighting) and four-year period (80% weighting), measured for periods ending on December 31. The accounts, which include the fund, are ranked against a group of mutual funds with similar investment objectives and investment focus (60%) and a broad-based securities market index measuring the performance of the same type of securities in which the accounts invest (40%), which, in the case of the fund, is the Russell 1000 Growth Index. As a result of 39 these two benchmarks, the performance of the portfolio manager for compensation purposes is measured against the criteria that are relevant to the portfolio manager's competitive universe. o Qualitative Performance. The qualitative performance component with respect to all of the accounts managed by the portfolio manager includes objectives, such as effectiveness in the areas of teamwork, leadership, communications and marketing, that are mutually established and evaluated by each portfolio manager and management. o Pioneer Results and Business Line Results. Pioneer's financial performance, as well as the investment performance of its investment management group, affect a portfolio manager's actual bonus by a leverage factor of plus or minus (+/-) a predetermined percentage. The quantitative and qualitative performance components comprise 80% and 20%, respectively, of the overall bonus calculation (on a pre-adjustment basis). A portion of the annual bonus is deferred for a specified period and may be invested in one or more Pioneer funds. Certain portfolio managers may participate in other programs designed to reward and retain key contributors. Senior executives or other key employees may be granted performance units based on the stock price performance of UniCredito Italiano and the financial performance of Pioneer Global Asset Management S.p.A., which are affiliates of Pioneer. Portfolio managers also may participate in a deferred compensation program, whereby deferred amounts are invested in one or more Pioneer funds. Share Ownership by Portfolio Managers. The following table indicates as of December 31, 2006 the value, within the indicated range, of shares beneficially owned by the portfolio managers of the fund.

PORTFOLIO TRANSACTIONS All orders for the purchase or sale of portfolio securities are placed on behalf of the fund by Pioneer pursuant to authority contained in the fund's management contract. Securities purchased and sold on behalf of the fund normally will be traded in the over-the counter market on a net basis (i.e. without commission) through dealers acting for their own account and not as brokers or otherwise through transactions directly with the issuer of the instrument. The cost of securities purchased from underwriters includes an underwriter's commission or concession, and the prices at which securities are purchased and sold from and to dealers include a dealer's markup or markdown. Pioneer normally seeks to deal directly with the primary market makers unless, in its opinion, better prices are available elsewhere. Some securities are purchased and sold on an exchange or in over-the-counter transactions conducted on an 40 agency basis involving a commission. Pioneer seeks to obtain the best execution on portfolio trades. The price of securities and any commission rate paid are always factors, but frequently not the only factors, in judging best execution. In selecting brokers or dealers, Pioneer considers various relevant factors, including, but not limited to, the size and type of the transaction; the nature and character of the markets for the security to be purchased or sold; the execution efficiency, settlement capability and financial condition of the dealer; the dealer's execution services rendered on a continuing basis; and the reasonableness of any dealer spreads. Transactions in non-U.S. equity securities are executed by broker-dealers in non-U.S. countries in which commission rates may not be negotiable (as such rates are in the U.S.). Pioneer may select broker-dealers that provide brokerage and/or research services to the fund and/or other investment companies or other accounts managed by Pioneer over which it or its affiliates exercise investment discretion. In addition, consistent with Section 28(e) of the Securities Exchange Act of 1934, as amended, if Pioneer determines in good faith that the amount of commissions charged by a broker-dealer is reasonable in relation to the value of the brokerage and research services provided by such broker, the fund may pay commissions to such broker-dealer in an amount greater than the amount another firm may charge. Such services may include advice concerning the value of securities; the advisability of investing in, purchasing or selling securities; the availability of securities or the purchasers or sellers of securities; providing stock quotation services, credit rating service information and comparative fund statistics; furnishing analyses, electronic information services, manuals and reports concerning issuers, industries, securities, economic factors and trends, portfolio strategy, and performance of accounts and particular investment decisions; and effecting securities transactions and performing functions incidental thereto (such as clearance and settlement). Pioneer maintains a listing of broker-dealers who provide such services on a regular basis. However, because many transactions on behalf of the fund and other investment companies or accounts managed by Pioneer are placed with broker-dealers (including broker-dealers on the listing) without regard to the furnishing of such services, it is not possible to estimate the proportion of such transactions directed to such dealers solely because such services were provided. Pioneer believes that no exact dollar value can be calculated for such services. The research received from broker-dealers may be useful to Pioneer in rendering investment management services to the fund as well as other investment companies or other accounts managed by Pioneer, although not all such research may be useful to the fund. Conversely, such information provided by brokers or dealers who have executed transaction orders on behalf of such other accounts may be useful to Pioneer in carrying out its obligations to the fund. The receipt of such research has not reduced Pioneer's normal independent research activities; however, it enables Pioneer to avoid the additional expenses which might otherwise be incurred if it were to attempt to develop comparable information through its own staff. The fund may participate in third-party brokerage and/or expense offset arrangements to reduce the fund's total operating expenses. Pursuant to third-party brokerage arrangements, the fund may incur lower expenses by directing brokerage to third-party broker-dealers which have agreed to use part of their commission to pay the fund's fees to service providers unaffiliated with Pioneer or other expenses. Since the commissions paid to the third party brokers reflect a commission cost that the fund would generally expect to incur on its brokerage transactions but not necessarily the lowest possible commission, this arrangement is intended to reduce the fund's operating expenses without increasing the cost of its brokerage commissions. Since use of such directed brokerage is subject to the requirement to achieve best execution in connection with the fund's brokerage transactions, there can be no assurance that such arrangements will be utilized. Pursuant to expense offset arrangements, the fund may incur lower transfer agency expenses due to interest earned on cash held with the transfer agent. See "Financial highlights" in the prospectus. 41 See the table in "Annual Fee, Expense and Other Information" for aggregate brokerage and underwriting commissions paid by the fund in connection with its portfolio transactions during recently completed fiscal years. The Board of Trustees periodically reviews Pioneer's performance of its responsibilities in connection with the placement of portfolio transactions on behalf of the fund. 11. DESCRIPTION OF SHARES As an open-end management investment company, the fund continuously offers its shares to the public and under normal conditions must redeem its shares upon the demand of any shareholder at the next determined net asset value per share less any applicable CDSC. See "Sales Charges." When issued and paid for in accordance with the terms of the prospectuses and statements of additional information, shares of the fund are fully paid and non-assessable. Shares will remain on deposit with the fund's transfer agent and certificates will not normally be issued. The fund's Agreement and Declaration of Trust, dated as of December 8, 1997, as amended and restated from time to time (the "Declaration"), permits the Board of Trustees to authorize the issuance of an unlimited number of full and fractional shares of beneficial interest which may be divided into such separate series as the Trustees may establish. Currently, the fund consists of only one series. The Trustees may, however, establish additional series of shares and may divide or combine the shares into a greater or lesser number of shares without thereby changing the proportionate beneficial interests in the fund. The Declaration further authorizes the Trustees to classify or reclassify any series of the shares into one or more classes. Pursuant thereto, the Trustees have authorized the issuance of four classes of shares of the fund, designated as Class A shares, Class C shares, Class Y shares and Class P shares. Each share of a class of the fund represents an equal proportionate interest in the assets of the fund allocable to that class. Upon liquidation of the fund, shareholders of each class of the fund are entitled to share pro rata in the fund's net assets allocable to such class available for distribution to shareholders. The fund reserves the right to create and issue additional series or classes of shares, in which case the shares of each class of a series would participate equally in the earnings, dividends and assets allocable to that class of the particular series. Shareholders are entitled to one vote for each share held and may vote in the election of Trustees and on other matters submitted to a meeting of shareholders. Although Trustees are not elected annually by the shareholders, shareholders have, under certain circumstances, the right to remove one or more Trustees. The fund is not required, and does not intend, to hold annual shareholder meetings although special meetings may be called for the purpose of electing or removing Trustees, changing fundamental investment restrictions or approving a management contract. The shares of each class represent an interest in the same portfolio of investments of the fund. Each class has equal rights as to voting, redemption, dividends and liquidation, except that each class bears different distribution and transfer agent fees and may bear other expenses properly attributable to the particular class. Class A and Class C shareholders have exclusive voting rights with respect to the Rule 12b-1 Plans adopted by holders of those shares in connection with the distribution of shares. The shares of each series of the fund are entitled to vote separately to approve investment advisory agreements or changes in investment restrictions, but shareholders of all series vote together in the election and selection of Trustees and accountants. Shares of all series of the fund vote together as a class on matters that affect all series of the fund in substantially the same manner. As to matters affecting a single series or class, shares of such series or class will vote separately. No amendment adversely 42 affecting the rights of shareholders may be made to the Declaration without the affirmative vote of a majority of the fund's shares. Shares have no preemptive or conversion rights. As a Delaware statutory trust, the fund's operations are governed by the Declaration. A copy of the fund's Certificate of Trust, dated December 8, 1997, is on file with the office of the Secretary of State of Delaware. Generally, Delaware statutory trust shareholders are not personally liable for obligations of the Delaware statutory trust under Delaware law. The Delaware Statutory Trust Act (the "Delaware Act") provides that a shareholder of a Delaware statutory trust shall be entitled to the same limitation of liability extended to shareholders of private for-profit corporations. The Declaration expressly provides that the fund is organized under the Delaware Act and that the Declaration is to be governed by Delaware law. There is nevertheless a possibility that a Delaware statutory trust, such as the fund, might become a party to an action in another state whose courts refused to apply Delaware law, in which case the fund's shareholders could become subject to personal liability. To guard against this risk, the Declaration (i) contains an express disclaimer of shareholder liability for acts or obligations of the fund and provides that notice of such disclaimer may be given in each agreement, obligation or instrument entered into or executed by the fund or its Trustees, (ii) provides for the indemnification out of fund property of any shareholders held personally liable for any obligations of the fund or any series of the fund and (iii) provides that the fund shall, upon request, assume the defense of any claim made against any shareholder for any act or obligation of the fund and satisfy any judgment thereon. Thus, the risk of a shareholder incurring financial loss beyond his or her investment because of shareholder liability is limited to circumstances in which all of the following factors are present: (1) a court refused to apply Delaware law; (2) the liability arose under tort law or, if not, no contractual limitation of liability was in effect; and (3) the fund itself would be unable to meet its obligations. In light of Delaware law, the nature of the fund's business and the nature of its assets, the risk of personal liability to a fund shareholder is remote. In addition to the requirements under Delaware law, the Declaration provides that a shareholder of the fund may bring a derivative action on behalf of the fund only if the following conditions are met: (a) shareholders eligible to bring such derivative action under Delaware law who hold at least 10% of the outstanding shares of the fund, or 10% of the outstanding shares of the series or class to which such action relates, shall join in the request for the Trustees to commence such action; and (b) the Trustees must be afforded a reasonable amount of time to consider such shareholder request and investigate the basis of such claim. The Trustees shall be entitled to retain counsel or other advisers in considering the merits of the request and shall require an undertaking by the shareholders making such request to reimburse the fund for the expense of any such advisers in the event that the Trustees determine not to bring such action. The Declaration further provides that the fund shall indemnify each of its Trustees and officers against liabilities and expenses reasonably incurred by them in connection with, or arising out of, any action, suit or proceeding, threatened against or otherwise involving such Trustee or officer, directly or indirectly, by reason of being or having been a Trustee or officer of the fund. The Declaration does not authorize the fund to indemnify any Trustee or officer against any liability to which he or she would otherwise be subject by reason of or for willful misfeasance, bad faith, gross negligence or reckless disregard of such person's duties. The Declaration provides that any Trustee who is not an "interested person" of Pioneer shall be considered to be independent for purposes of Delaware law notwithstanding the fact that such Trustee receives compensation for serving as a trustee of the fund or other investment companies for which Pioneer acts as investment adviser. 43 12. SALES CHARGES The fund continuously offers four classes of shares designated as Class A shares, Class C shares, Class Y shares and Class P shares as described in the prospectuses and the statements of additional information. The fund offers its shares at a reduced sales charge to investors who meet certain criteria that permit the fund's shares to be sold with low distribution costs. These criteria are described below or in the Class A and Class C shares prospectus. Creation and sales charges on purchases or sales of Class P shares are described in the fund's Class P shares prospectus and statement of additional information. Class A Share Sales Charges You may buy Class A shares at the public offering price, including a sales charge, as follows: Sales Charge as a % of ---------------------- Offering Net Amount Dealer Amount of Purchase Price Invested Reallowance Less than $50,000 5.75 6.10 5.00 $50,000 but less than $100,000 4.50 4.71 4.00 $100,000 but less than $250,000 3.50 3.63 3.00 $250,000 but less than $500,000 2.50 2.56 2.00 $500,000 but less than $1,000,000 2.00 2.04 1.75 $1,000,000 or more 0.00 0.00 see below The schedule of sales charges above is applicable to purchases of Class A shares of the fund by (i) an individual, (ii) an individual and his or her spouse and children under the age of 21 and (iii) a trustee or other fiduciary of a trust estate or fiduciary account or related trusts or accounts including pension, profit-sharing and other employee benefit trusts qualified under Sections 401 or 408 of the Code although more than one beneficiary is involved. The sales charges applicable to a current purchase of Class A shares of the fund by a person listed above is determined by adding the value of shares to be purchased to the aggregate value (at the then current offering price) of shares of any of the other Pioneer mutual funds previously purchased and then owned, provided PFD is notified by such person or his or her broker-dealer each time a purchase is made which would qualify. Pioneer mutual funds include all mutual funds for which PFD serves as principal underwriter. At the sole discretion of PFD, holdings of funds domiciled outside the U.S., but which are managed by affiliates of Pioneer, may be included for this purpose. No sales charge is payable at the time of purchase on investments of $1 million or more, or for purchases by participants in employer-sponsored retirement plans described below subject to a CDSC of 1% which may be imposed in the event of a redemption of Class A shares within 18 months of purchase (one year of purchase for shares purchased prior to February 1, 2004). PFD may, in its discretion, pay a commission to broker-dealers who initiate and are responsible for such purchases as follows: Accounts Other than Employer-Sponsored Retirement Plans 1.00% Up to $4 million 0.50% Next $46 million 0.25% Over $50 million Employer-Sponsored Retirement Plans 0.50% Up to $50 million 0.25% Over $50 million 44 These commissions shall not be payable if the purchaser is affiliated with the broker-dealer or if the purchase represents the reinvestment of a redemption made during the previous 12 calendar months. Broker-dealers who receive a commission in connection with Class A share purchases at net asset value by employer-sponsored retirement plans with at least $10 million in total plan assets (or that has 1,000 or more eligible participants for employer-sponsored retirement plans with accounts established with Pioneer on or before March 31, 2004) will be required to return any commissions paid or a pro rata portion thereof if the retirement plan redeems its shares within 18 months of purchase. Letter of Intent ("LOI"). Reduced sales charges are available for purchases of $100,000 or more of Class A shares (excluding any reinvestments of dividends and capital gain distributions) made within a 13-month period pursuant to an LOI which may be established by completing the Letter of Intent section of the Account Application. The reduced sales charge will be the charge that would be applicable to the purchase of the specified amount of Class A shares as if the shares had all been purchased at the same time. A purchase not made pursuant to an LOI may be included if the LOI is submitted to PIMSS within 90 days of such purchase. You may also obtain the reduced sales charge by including the value (at current offering price) of all your Class A shares in the fund and all other Pioneer mutual funds held of record as of the date of your LOI in the amount used to determine the applicable sales charge for the Class A shares to be purchased under the LOI. Five percent of your total intended purchase amount will be held in escrow by PIMSS, registered in your name, until the terms of the LOI are fulfilled. When you sign the Account Application, you agree to irrevocably appoint PIMSS your attorney-in-fact to surrender for redemption any or all shares held in escrow with full power of substitution. An LOI is not a binding obligation upon the investor to purchase, or the fund to sell, the amount specified in the LOI. If the total purchases, less redemptions, exceed the amount specified under the LOI and are in an amount that would qualify for a further quantity discount, all transactions will be recomputed on the expiration date of the LOI to effect the lower sales charge. Any difference in the sales charge resulting from such recomputation will be either delivered to you in cash or invested in additional shares at the lower sales charge. The dealer, by signing the Account Application, agrees to return to PFD, as part of such retroactive adjustment, the excess of the commission previously reallowed or paid to the dealer over that which is applicable to the actual amount of the total purchases under the LOI. If the total purchases, less redemptions, are less than the amount specified under the LOI, you must remit to PFD any difference between the sales charge on the amount actually purchased and the amount originally specified in the LOI. When the difference is paid, the shares held in escrow will be deposited to your account. If you do not pay the difference in sales charge within 20 days after written request from PFD or your dealer, PIMSS, after receiving instructions from PFD, will redeem the appropriate number of shares held in escrow to realize the difference and release any excess. Class C Shares You may buy Class C shares at net asset value per share next computed after receipt of a purchase order without the imposition of an initial sales charge; however, Class C shares redeemed within one year of purchase will be subject to a CDSC of 1%. The charge will be assessed on the amount equal to the lesser of the current market value or the original purchase cost of the shares being redeemed. No CDSC will be imposed on increases in account value above the initial purchase price, including shares derived from the reinvestment of dividends or capital gain distributions. Class C shares do not convert to any other class of fund shares. 45 In processing redemptions of Class C shares, the fund will first redeem shares not subject to any CDSC and then shares held for the longest period of time during the one-year period. As a result, you will pay the lowest possible CDSC. Proceeds from the CDSC are paid to PFD and are used in whole or in part to defray PFD's expenses related to providing distribution-related services to the fund in connection with the sale of Class C shares, including the payment of compensation to broker-dealers. Class Y Shares No front-end, deferred or asset based sales charges are applicable to Class Y shares. Additional Payments to Financial Intermediaries The financial intermediaries through which shares are purchased may receive all or a portion of the sales charges and Rule 12b-1 fees discussed above. In addition to those payments, Pioneer or one or more of its affiliates (collectively, "Pioneer Affiliates") may make additional payments to financial intermediaries in connection with the promotion and sale of shares of Pioneer funds. Pioneer Affiliates make these payments from their own resources, which include resources that derive from compensation for providing services to the Pioneer funds. These additional payments are described below. The categories described below are not mutually exclusive. The same financial intermediary may receive payments under more than one or all categories. Many financial intermediaries that sell shares of Pioneer funds receive one or more types of these payments. The financial intermediary typically initiates requests for additional compensation. Pioneer negotiates these arrangements individually with financial intermediaries and the amount of payments and the specific arrangements may differ significantly. A financial intermediary also may receive different levels of compensation with respect to sales or assets attributable to different types of clients of the same intermediary or different Pioneer funds. Where services are provided, the costs of providing the services and the overall array of services provided may vary from one financial intermediary to another. Pioneer Affiliates do not make an independent assessment of the cost of providing such services. While the financial intermediaries may request additional compensation from Pioneer to offset costs incurred by the financial intermediary in servicing its clients, the financial intermediary may earn a profit on these payments, since the amount of the payment may exceed the financial intermediary's costs. In this context, "financial intermediary" includes any broker, dealer, bank (including bank trust departments), insurance company, transfer agent, registered investment adviser, financial planner, retirement plan administrator and any other financial intermediary having a selling, administrative and shareholder servicing or similar agreement with a Pioneer Affiliate. A financial intermediary's receipt of additional compensation may create conflicts of interest between the financial intermediary and its clients. Each type of payment discussed below may provide your financial intermediary with an economic incentive to actively promote the Pioneer funds over other mutual funds or cooperate with the distributor's promotional efforts. The receipt of additional compensation for Pioneer Affiliates may be an important consideration in a financial intermediary's willingness to support the sale of the Pioneer funds through the financial intermediary's distribution system. Pioneer Affiliates are motivated to make the payments described above since they promote the sale of Pioneer fund shares and the retention of those investments by clients of financial intermediaries. In certain cases these payments could be significant to the financial intermediary. The financial intermediary may charge additional fees or commissions other than those disclosed in the prospectus. Financial intermediaries may categorize and disclose these arrangements differently than Pioneer Affiliates do. To the extent financial intermediaries sell more shares of the funds or retain shares of the funds in their clients' accounts, Pioneer Affiliates benefit from the incremental management and other fees paid to Pioneer Affiliates by the funds 46 with respect to those assets. Revenue Sharing Payments. Pioneer Affiliates make revenue sharing payments as incentives to certain financial intermediaries to promote and sell shares of Pioneer funds. The benefits Pioneer Affiliates receive when they make these payments include, among other things, entry into or increased visibility in the financial intermediary's sales system, participation by the intermediary in the distributor's marketing efforts (such as helping facilitate or providing financial assistance for conferences, seminars or other programs at which Pioneer personnel may make presentations on the funds to the intermediary's sales force), placement on the financial intermediary's preferred fund list, and access (in some cases, on a preferential basis over other competitors) to individual members of the financial intermediary's sales force or management. Revenue sharing payments are sometimes referred to as "shelf space" payments because the payments compensate the financial intermediary for including Pioneer funds in its fund sales system (on its "shelf space"). Pioneer Affiliates compensate financial intermediaries differently depending typically on the level and/or type of considerations provided by the financial intermediary. The revenue sharing payments Pioneer Affiliates make may be calculated on sales of shares of Pioneer funds ("Sales-Based Payments"); although there is no policy limiting the amount of Sales-Based Payments any one financial intermediary may receive, the total amount of such payments normally does not exceed 0.25% per annum of those assets. Such payments also may be calculated on the average daily net assets of the applicable Pioneer funds attributable to that particular financial intermediary ("Asset-Based Payments"); although there is no policy limiting the amount of Asset-Based Payments any one financial intermediary may receive, the total amount of such payments normally does not exceed 0.15% per annum of those assets. Sales-Based Payments primarily create incentives to make new sales of shares of Pioneer funds and Asset-Based Payments primarily create incentives to retain previously sold shares of Pioneer funds in investor accounts. Pioneer Affiliates may pay a financial intermediary either or both Sales-Based Payments and Asset-Based Payments. Administrative and Processing Support Payments. Pioneer Affiliates also may make payments to certain financial intermediaries that sell Pioneer fund shares for certain administrative services, including record keeping and sub-accounting shareholder accounts, to the extent that the funds do not pay for these costs directly. Pioneer Affiliates also may make payments to certain financial intermediaries that sell Pioneer fund shares in connection with client account maintenance support, statement preparation and transaction processing. The types of payments that Pioneer Affiliates may make under this category include, among others, payment of ticket charges per purchase or exchange order placed by a financial intermediary, payment of networking fees in connection with certain mutual fund trading systems, or one-time payments for ancillary services such as setting up funds on a financial intermediary's mutual fund trading system. Other Payments. From time to time, Pioneer Affiliates, at their expense, may provide additional compensation to financial intermediaries which sell or arrange for the sale of shares of the Pioneer funds. Such compensation provided by Pioneer Affiliates may include financial assistance to financial intermediaries that enable Pioneer Affiliates to participate in and/or present at conferences or seminars, sales or training programs for invited registered representatives and other employees, client entertainment, client and investor events, and other financial intermediary-sponsored events, and travel expenses, including lodging incurred by registered representatives and other employees in connection with client prospecting, retention and due diligence trips. Other compensation may be offered to the extent not prohibited by federal or state laws or any self-regulatory agency, such as the NASD. Pioneer Affiliates make payments for entertainment events they deem appropriate, subject to Pioneer Affiliates' guidelines and applicable law. These payments may vary depending upon the nature of the event or the relationship. 47 As of January 1, 2007, Pioneer anticipates that the following broker-dealers or their affiliates will receive additional payments as described in the fund's prospectuses and statement of additional information: A.

REDEEMING SHARES Redemptions may be suspended or payment postponed during any period in which any of the following conditions exist: the New York Stock Exchange (the "Exchange") is closed or trading on the Exchange is restricted; an emergency exists as a result of which disposal by the fund of securities owned by it is not reasonably practicable or it is not reasonably practicable for the fund to fairly determine the value of the net assets of its portfolio; or the SEC, by order, so permits. Redemptions and repurchases are taxable transactions for shareholders that are subject to U.S. federal income tax. The net asset value per share received upon redemption or repurchase may be more or less than the cost of shares to an investor, depending on the market value of the portfolio at the time of redemption or repurchase. Systematic Withdrawal Plan(s) ("SWP") (Class A and Class C Shares). A SWP is designed to provide a convenient method of receiving fixed payments at regular intervals from fund share accounts having a total value of not less than $10,000. You must also be reinvesting all dividends and capital gain distributions to use the SWP option. Periodic payments of $50 or more will be deposited monthly, quarterly, semiannually or annually directly into a bank account designated by the applicant or will be sent by check to the applicant, or any person designated by the applicant. Payments can be made either by check or electronic funds transfer to a bank account designated by you. Withdrawals from Class C share accounts are limited to 10% of the value of the account at the time the SWP is established. See "Qualifying for a reduced sales charge" in the prospectus. If you direct that withdrawal payments be paid to another person, want to change the bank where payments are sent or designate an address that is different from the account's address of record after you have opened your account, a medallion signature guarantee must accompany your instructions. Withdrawals under the SWP are redemptions that may have tax consequences for you. Purchases of Class A shares of the fund at a time when you have a SWP in effect may result in the payment of unnecessary sales charges and may, therefore, be disadvantageous. SWP redemptions reduce and may ultimately exhaust the number of shares in your account. In addition, the amounts received by a 49 shareholder cannot be considered as yield or income on his or her investment because part of such payments may be a return of his or her investment. A SWP may be terminated at any time (1) by written notice to PIMSS or from PIMSS to the shareholder; (2) upon receipt by PIMSS of appropriate evidence of the shareholder's death; or (3) when all shares in the shareholder's account have been redeemed. You may obtain additional information by calling PIMSS at 1-800-225-6292. Reinstatement Privilege (Class A Shares). Subject to the provisions outlined in the prospectus, you may reinvest all or part of your sale proceeds from Class A shares without a sales charge into Class A shares of a Pioneer mutual fund. However, the distributor will not pay your investment firm a commission on any reinvested amount. 14. TELEPHONE AND ONLINE TRANSACTIONS You may purchase, exchange or sell Class A or Class C shares by telephone or online. Class Y shares may not be purchased by telephone and Class Y shareowners are not eligible for online transaction privileges. See the prospectuses for more information. For personal assistance, call 1-800-225-6292 between 8:00 a.m. and 7:00 p.m. Eastern time on weekdays. (Class Y account holders should contact Pioneer's Group Plans Department at 1-888-294-4480 between 9:00 a.m. and 6:0 p.m. Eastern time on weekdays.) Computer-assisted telephone transactions may be available to shareholders who have prerecorded certain bank information (see "FactFone(SM)"). You are strongly urged to consult with your investment professional prior to requesting any telephone or online transaction. Telephone Transaction Privileges. To confirm that each transaction instruction received by telephone is genuine, the fund will record each telephone transaction, require the caller to provide validating information for the account and send you a written confirmation of each telephone transaction. Different procedures may apply to accounts that are registered to non-U.S. citizens or that are held in the name of an institution or in the name of an investment broker-dealer or other third party. If reasonable procedures, such as those described above, are not followed, the fund may be liable for any loss due to unauthorized or fraudulent instructions. The fund may implement other procedures from time to time. In all other cases, neither the fund, PIMSS nor PFD will be responsible for the authenticity of instructions received by telephone; therefore, you bear the risk of loss for unauthorized or fraudulent telephone transactions. Online Transaction Privileges. If your account is registered in your name, you may be able buy, exchange or sell fund shares online. Your investment firm may also be able to buy, exchange or sell your fund shares online. To establish online transaction privileges: o For new accounts, complete the online section of the account application o For existing accounts, complete an account options form, write to the transfer agent or complete the online authorization screen on www.pioneerfunds.com To use online transactions, you must read and agree to the terms of an online transaction agreement available on the Pioneer website. When you or your investment firm requests an online transaction the transfer agent electronically records the transaction, requires an authorizing password and sends a written confirmation. The fund may implement other procedures from time to time. Different procedures may apply if you have a non-U.S. account or if your account is registered in the name of an institution, broker- 50 dealer or other third party. You may not be able to use the online transaction privilege for certain types of accounts, including most retirement accounts. Telephone and Website Online Access. You may have difficulty contacting the fund by telephone or accessing www.pioneerfunds.com during times of market volatility or disruption in telephone or Internet services. On Exchange holidays or on days when the Exchange closes early, Pioneer will adjust the hours for the telephone center and for online transaction processing accordingly. If you are unable to access pioneerfunds.com or to reach the fund by telephone, you should communicate with the fund in writing. FactFone(SM). FactFone(SM) is an automated inquiry and telephone transaction system available to Pioneer mutual fund shareholders by dialing 1-800-225-4321. FactFone(SM) allows shareholder access to current information on Pioneer mutual fund accounts and to the prices and yields of all publicly available Pioneer mutual funds. In addition, you may use FactFone(SM) to make computer-assisted telephone purchases, exchanges or redemptions from your Pioneer mutual fund accounts, access your account balances and last three transactions and order a duplicate statement if you have activated your PIN. Telephone purchases or redemptions require the establishment of a bank account of record. Computer-assisted Class Y share telephone purchases, exchanges and redemptions and certain other FactFone(SM) features for Class Y shareholders are not currently available through FactFone(SM). You are strongly urged to consult with your investment professional prior to requesting any telephone transaction. Shareholders whose accounts are registered in the name of a broker-dealer or other third party may not be able to use FactFone(SM). Call PIMSS for assistance. FactFone(SM) allows shareholders to hear the following recorded fund information: o net asset value prices for all Pioneer mutual funds; o annualized 30-day yields on Pioneer's fixed income funds; o annualized 7-day yields and 7-day effective (compound) yields for Pioneer's money market funds; and o dividends and capital gain distributions on all Pioneer mutual funds. Yields are calculated in accordance with SEC mandated standard formulas. All performance numbers communicated through FactFone(SM) represent past performance, and figures include the maximum applicable sales charge. A shareholder's actual yield and total return will vary with changing market conditions. The value of each class of shares (except for Pioneer Cash Reserves Fund, Pioneer Institutional Money Market Fund, Pioneer Tax Free Money Market Fund and Pioneer Treasury Reserves Fund, which each seek to maintain a stable $1.00 share price) will also vary, and such shares may be worth more or less at redemption than their original cost. 15. PRICING OF SHARES The net asset value per share of each class of the fund is determined as of the close of regular trading on the Exchange (normally 4:00 p.m. Eastern time) on each day on which the Exchange is open for trading. As of the date of this statement of additional information, the Exchange is open for trading every weekday except for the days the following holidays are observed: New Year's Day, Martin Luther King, Jr. Day, Presidents' Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and 51 Christmas Day. The net asset value per share of each class of the fund is also determined on any other day on which the level of trading in its portfolio securities is sufficiently high that the current net asset value per share might be materially affected by changes in the value of its portfolio securities. The fund is not required to determine its net asset value per share on any day on which no purchase orders in good order for fund shares are received and no shares are tendered and accepted for redemption. The fund generally values its portfolio securities using closing market prices or readily available market quotations. The fund may use a pricing service or a pricing matrix to value some of its assets. Securities which have not traded on the date of valuation or securities for which sales prices are not generally reported are valued at the mean between the current bid and asked prices. Securities quoted in foreign currencies are converted to U.S. dollars utilizing foreign exchange rates employed by the fund's independent pricing services. Generally, trading in non-U.S. securities is substantially completed each day at various times prior to the close of regular trading on the Exchange. The values of such securities used in computing the net asset value of the fund's shares are determined as of such times. Foreign currency exchange rates are also generally determined prior to the close of regular trading on the Exchange. When closing market prices or market quotations are not available or are considered by Pioneer to be unreliable, the fund uses a security's fair value. Fair value is the valuation of a security determined on the basis of factors other than market value in accordance with procedures approved by the fund's Trustees. The fund also may use the fair value of a security, including a non-U.S. security, when Pioneer determines that the closing market price on the primary exchange where the security is traded no longer accurately reflects the value of the security due to factors affecting one or more relevant securities markets or the specific issuer. The use of fair value pricing by the fund may cause the net asset value of its shares to differ from the net asset value that would be calculated using closing market prices. International securities markets may be open on days when the U.S. markets are closed. For this reason, the value of any international securities owned by the fund could change on a day you cannot buy or sell shares of the fund. In connection with making fair value determinations of the value of fixed income securities, the fund's Trustees may use a pricing matrix. Debt securities with remaining maturities of 60 days or less are valued at amortized cost, which is a method of determining a security's fair value. The net asset value per share of each class of the fund is computed by taking the value of all of the fund's assets, less the fund's liabilities, and dividing the result by the number of outstanding shares of the fund. For purposes of determining net asset value, expenses of the fund are accrued daily and taken into account. The fund's maximum offering price per Class A share is determined by adding the maximum sales charge to the net asset value per Class A share. Class C and Class Y shares are offered at net asset value without the imposition of an initial sales charge (Class C shares may be subject to a CDSC). 16. TAX STATUS The fund has elected to be treated, has qualified and intends to continue to qualify each year as a "regulated investment company" under Subchapter M of the Code so that it will not pay U.S. federal income tax on income and capital gains distributed to shareholders (provided that the distribution requirements set forth below are satisfied). In order to qualify as a regulated investment company under Subchapter M of the Code, the fund must, among other things, (i) derive at least 90% of its gross income for each taxable year from dividends, interest, payments with respect to securities loans, gains from the sale or other disposition of stock, securities or foreign currencies, or other income (including gains from options, futures and forward contracts) derived with respect to its business of investing in such stock, securities or currencies and net income derived from an interest in a qualified publicly traded partnership (as defined in Section 851(h) of the Code) (the "90% income test") and (ii) diversify its holdings so that, at the end of each quarter of each taxable year: (a) at least 50% of the value of the fund's total assets is represented by (1) cash and cash items, U.S. government securities, securities of other regulated 52 investment companies, and (2) other securities, with such other securities limited, in respect to any one issuer, to an amount not greater than 5% of the value of the fund's total assets and to not more than 10% of the outstanding voting securities of such issuer and (b) not more than 25% of the value of the fund's total assets is invested in (1) the securities (other than U.S. government securities and securities of other regulated investment companies) of any one issuer, (2) the securities (other than securities of other regulated investment companies) of two or more issuers that the fund controls and that are engaged in the same, similar, or related trades or businesses, or (3) the securities of one or more qualified publicly traded partnerships. For purposes of the 90% income test, the character of income earned by certain entities in which the fund invests that are not treated as corporations for U.S. federal income tax purposes (e.g., partnerships (other than qualified publicly traded partnerships) or trusts) will generally pass through to the fund. Consequently, the fund may be required to limit its equity investments in such entities that earn fee income, rental income or other nonqualifying income. If the fund qualifies as a regulated investment company and properly distributes to its shareholders each taxable year an amount equal to or exceeding the sum of (i) 90% of its "investment company taxable income" as that term is defined in the Code (which includes, among other things, dividends, taxable interest, and the excess of any net short-term capital gains over net long-term capital losses, as reduced by certain deductible expenses) without regard to the deduction for dividends paid and (ii) 90% of the excess of its gross tax-exempt interest, if any, over certain disallowed deductions, the fund generally will not be subject to U.S. federal income tax on any income of the fund, including "net capital gain" (the excess of net long-term capital gain over net short-term capital loss), distributed to shareholders. However, if the fund meets such distribution requirements, but chooses to retain some portion of its investment company taxable income or net capital gain, it generally will be subject to U.S. federal income tax at regular corporate rates on the amount retained. The fund intends to distribute at least annually all or substantially all of its investment company taxable income, net tax-exempt interest, and net capital gain. If the fund does not qualify as a regulated investment company for any taxable year, it will be treated as a U.S. corporation subject to U.S. federal income tax, thereby subjecting any income earned by the fund to tax at the corporate level and to a further tax at the shareholder level when such income is distributed. Under the Code, the fund will be subject to a nondeductible 4% U.S. federal excise tax on a portion of its undistributed ordinary income and capital gain net income if it fails to meet certain distribution requirements with respect to each calendar year. The fund intends to make distributions in a timely manner and accordingly does not expect to be subject to the excise tax. The fund generally distributes any net short- and long-term capital gains in November. The fund generally pays dividends from any net investment income in December. Dividends from income and/or capital gains may also be paid at such other times as may be necessary for the fund to avoid U.S. federal income or excise tax. Unless shareholders specify otherwise, all distributions from the fund will be automatically reinvested in additional full and fractional shares of the fund. For U.S. federal income tax purposes, all dividends generally are taxable whether a shareholder takes them in cash or reinvests them in additional shares of the fund. In general, assuming that the fund has sufficient earnings and profits, dividends from investment company taxable income are taxable either as ordinary income or, if so designated by the fund and certain other conditions are met, as "qualified dividend income" taxable to individual shareholders at a maximum 15% U.S. federal income tax rate. Dividend income distributed to individual shareholders will qualify for the maximum 15% U.S. federal income tax rate on dividends to the extent that such dividends are attributable to "qualified dividend income," as that term is defined in Section 1(h)(11)(B) of the Code, from the fund's investments in 53 common and preferred stock of U.S. companies and stock of certain qualified foreign corporations, provided that certain holding period and other requirements are met by both the fund and the shareholders. Dividends received by the fund from REITS are generally not expected to qualify for treatment as qualified dividend income. A foreign corporation generally is treated as a qualified foreign corporation if it is incorporated in a possession of the United States or it is eligible for the benefits of certain income tax treaties with the United States. A foreign corporation that does not meet such requirements will be treated as qualifying with respect to dividends paid by it if the stock with respect to which the dividends are paid is readily tradable on an established securities market in the United States. Dividends received by the fund from passive foreign investment companies will not qualify for the maximum 15% U.S. federal income tax rate. A dividend that is attributable to qualified dividend income of the fund that is paid by the fund to an individual shareholder will not be taxable as qualified dividend income to such shareholder if (1) the dividend is received with respect to any share of the fund held for fewer than 61 days during the 121-day period beginning on the date which is 60 days before the date on which such share became ex-dividend with respect to such dividend, (2) to the extent that the shareholder is under an obligation (whether pursuant to a short sale or otherwise) to make related payments with respect to positions in substantially similar or related property, or (3) the shareholder elects to have the dividend treated as investment income for purposes of the limitation on deductibility of investment interest. The "ex-dividend" date is the date on which the owner of the share at the commencement of such date is entitled to receive the next issued dividend payment for such share even if the share is sold by the owner on that date or thereafter. Dividends from net capital gain, if any, that are designated as capital gain dividends by the fund are taxable as long-term capital gains for U.S. federal income tax purposes without regard to the length of time the shareholder has held shares of the fund. Capital gain dividends distributed by the fund to individual shareholders generally will qualify for the maximum 15% U.S. federal income tax rate on long-term capital gains, subject to certain limited exceptions. A shareholder should also be aware that the benefits of the favorable tax rate applicable to long-term capital gains and qualified dividend income may be impacted by the application of the alternative minimum tax to individual shareholders. Under current law, the maximum 15% U.S. federal income tax rate on qualified dividend income and long-term capital gains will cease to apply to taxable years beginning after December 31, 2010. Distributions by the fund in excess of the fund's current and accumulated earnings and profits will be treated as a return of capital to the extent of (and in reduction of) the shareholder's tax basis in its shares and any such amount in excess of that basis will be treated as gain from the sale of shares, as discussed below. The U.S. federal income tax status of all distributions, including the portion of such distributions which may qualify for treatment as qualified dividend income, will be reported to shareholders annually. Although dividends generally will be treated as distributed when paid, any dividend declared by the fund as of a record date in October, November or December and paid during the following January will be treated for U.S. federal income tax purposes as received by shareholders on December 31 of the calendar year in which it is declared. In addition, certain other distributions made after the close of a taxable year of the fund may be "spilled back" and treated as paid by the fund (except for purposes of the 4% excise tax) during such taxable year. In such case, shareholders generally will be treated as having received such dividends in the taxable year in which the distributions were actually made. Foreign exchange gains and losses realized by the fund in connection with certain transactions involving foreign currency-denominated debt securities, certain options and futures contracts relating to foreign currency, foreign currency forward contracts, foreign currencies, or payables or receivables denominated in a foreign currency are subject to Section 988 of the Code, which generally causes such gains and losses 54 to be treated as ordinary income and losses and may affect the amount, timing and character of distributions to shareholders. Under Treasury regulations that may be promulgated in the future, any gains from such transactions that are not directly related to the fund's principal business of investing in stock or securities (or in options contracts or futures contracts with respect to stock or securities) may have to be limited in order to enable the fund to satisfy the 90% income test. If the net foreign exchange loss for a year were to exceed the fund's investment company taxable income (computed without regard to such loss), the resulting ordinary loss for such year would not be deductible by the fund or its shareholders in future years. If the fund acquires any equity interest (under Treasury regulations that may be promulgated in the future, generally including not only stock but also an option to acquire stock such as is inherent in a convertible bond) in certain foreign corporations that receive at least 75% of their annual gross income from passive sources (such as interest, dividends, certain rents and royalties, or capital gains) or that hold at least 50% of their assets in investments producing such passive income ("passive foreign investment companies"), the fund could be subject to U.S. federal income tax and additional interest charges on "excess distributions" received from such companies or on gain from the sale of stock in such companies, even if all income or gain actually received by the fund is timely distributed to its shareholders. The fund would not be able to pass through to its shareholders any credit or deduction for such a tax. Elections may generally be available that would ameliorate these adverse tax consequences, but such elections could require the fund to recognize taxable income or gain (subject to tax distribution requirements) without the concurrent receipt of cash. These investments could also result in the treatment of capital gains from the sale of stock of passive foreign investment companies as ordinary income. The fund may limit and/or manage its holdings in passive foreign investment companies to limit its tax liability or maximize its return from these investments. The fund may invest in debt obligations that are in the lowest rating categories or are unrated, including debt obligations of issuers not currently paying interest or who are in default. Investments in debt obligations that are at risk of or in default present special tax issues for the fund. Tax rules are not entirely clear about issues such as when the fund may cease to accrue interest, original issue discount or market discount, when and to what extent deductions may be taken for bad debts or worthless securities, how payments received on obligations in default should be allocated between principal and income and whether exchanges of debt obligations in a workout context are taxable. These and other issues will be addressed by the fund, in the event it invests in such securities, in order to seek to ensure that it distributes sufficient income to preserve its status as a regulated investment company and does not become subject to U.S. federal income or excise tax. If the fund invests in certain pay-in-kind securities, zero coupon securities, deferred interest securities or, in general, any other securities with original issue discount (or with market discount if the fund elects to include market discount in income currently), the fund generally must accrue income on such investments for each taxable year, which generally will be prior to the receipt of the corresponding cash payments. However, the fund must distribute, at least annually, all or substantially all of its investment company taxable income, including such accrued income, to shareholders to qualify as a regulated investment company under the Code and avoid U.S. federal income and excise taxes. Therefore, the fund may have to dispose of its portfolio securities under disadvantageous circumstances to generate cash, or may have to borrow the cash, to satisfy distribution requirements. For U.S. federal income tax purposes, the fund is permitted to carry forward a net capital loss for any year to offset its capital gains, if any, for up to eight years following the year of the loss. To the extent subsequent capital gains are offset by such losses, they would not result in U.S. federal income tax 55 liability to the fund and are not expected to be distributed as such to shareholders. See "Annual Fee, Expense and Other Information" for the fund's available capital loss carryforwards. At the time of an investor's purchase of fund shares, a portion of the purchase price may be attributable to realized or unrealized appreciation in the fund's portfolio or to undistributed taxable income of the fund. Consequently, subsequent distributions by the fund with respect to these shares from such appreciation or income may be taxable to such investor even if the net asset value of the investor's shares is, as a result of the distributions, reduced below the investor's cost for such shares and the distributions economically represent a return of a portion of the investment. Redemptions and exchanges generally are taxable events for shareholders that are subject to tax. Shareholders should consult their own tax advisers with reference to their individual circumstances to determine whether any particular transaction in fund shares is properly treated as a sale for tax purposes, as the following discussion assumes, and the tax treatment of any gains or losses recognized in such transactions. In general, if fund shares are sold, the shareholder will recognize gain or loss equal to the difference between the amount realized on the sale and the shareholder's adjusted basis in the shares. Such gain or loss generally will be treated as long-term capital gain or loss if the shares were held for more than one year and otherwise generally will be treated as short-term capital gain or loss. Any loss recognized by a shareholder upon the redemption, exchange or other disposition of shares with a tax holding period of six months or less will be treated as a long-term capital loss to the extent of any amounts treated as distributions of long-term capital gain with respect to such shares. In addition, if Class A shares that have been held for less than 91 days are redeemed and the proceeds are reinvested in Class A shares of the fund or in Class A shares of another mutual fund at net asset value pursuant to the reinstatement privilege, or if Class A shares in the fund that have been held for less than 91 days are exchanged for Class A shares of another fund at net asset value pursuant to the fund's exchange privilege, all or a portion of the sales charge paid on the shares that are redeemed or exchanged will not be included in the tax basis of such shares under the Code to the extent a sales charge that would otherwise apply to the shares received is reduced pursuant to the reinstatement or exchange privilege. In either case, the portion of the sales charge not included in the tax basis of the shares redeemed or surrendered in an exchange is included in the tax basis of the shares acquired in the exchange. Losses on redemptions or other dispositions of shares may be disallowed under "wash sale" rules in the event of other investments in the fund (including those made pursuant to reinvestment of dividends and/or capital gain distributions) within a period of 61 days beginning 30 days before and ending 30 days after a redemption or other disposition of shares. In such a case, the disallowed portion of any loss generally would be included in the U.S. federal tax basis of the shares acquired in the other investments. Under Treasury regulations, if a shareholder recognizes a loss with respect to fund shares of $2 million or more for an individual shareholder, or $10 million or more for a corporate shareholder, in any single taxable year (or greater amounts over a combination of years), the shareholder must file with the IRS a disclosure statement on Form 8886. Shareholders who own portfolio securities directly are in many cases excepted from this reporting requirement but, under current guidance, shareholders of regulated investment companies are not excepted. A shareholder who fails to make the required disclosure to the IRS may be subject to substantial penalties. The fact that a loss is reportable under these regulations does not affect the legal determination of whether or not the taxpayer's treatment of the loss is proper. Shareholders should consult with their tax advisers to determine the applicability of these regulations in light of their individual circumstances. Options written or purchased and futures contracts entered into by the fund on certain securities, indices and foreign currencies, as well as certain forward foreign currency contracts, may cause the fund to 56 recognize gains or losses from marking-to-market even though such options may not have lapsed, been closed out, or exercised, or such futures or forward contracts may not have been performed or closed out. The tax rules applicable to these contracts may affect the characterization of some capital gains and losses realized by the fund as long-term or short-term. Certain options, futures and forward contracts relating to foreign currency may be subject to Section 988 of the Code, as described above, and accordingly may produce ordinary income or loss. Additionally, the fund may be required to recognize gain if an option, futures contract, forward contract, short sale or other transaction that is not subject to the mark-to-market rules is treated as a "constructive sale" of an "appreciated financial position" held by the fund under Section 1259 of the Code. Any net mark-to-market gains and/or gains from constructive sales may also have to be distributed to satisfy the distribution requirements referred to above even though the fund may receive no corresponding cash amounts, possibly requiring the disposition of portfolio securities or borrowing to obtain the necessary cash. Losses on certain options, futures or forward contracts and/or offsetting positions (portfolio securities or other positions with respect to which the fund's risk of loss is substantially diminished by one or more options, futures or forward contracts) may also be deferred under the tax straddle rules of the Code, which may also affect the characterization of capital gains or losses from straddle positions and certain successor positions as long-term or short-term. Certain tax elections may be available that would enable the fund to ameliorate some adverse effects of the tax rules described in this paragraph. The tax rules applicable to options, futures, forward contracts and straddles may affect the amount, timing and character of the fund's income and gains or losses and hence of its distributions to shareholders. Dividends received by the fund from U.S. corporations in respect of any share of stock with a tax holding period of at least 46 days (91 days in the case of certain preferred stock) extending before and after each dividend held in an unleveraged position and distributed and designated by the fund (except for capital gain dividends received from a regulated investment company) may be eligible for the 70% dividends-received deduction generally available to corporations under the Code. Any corporate shareholder should consult its tax adviser regarding the possibility that its tax basis in its shares may be reduced, for U.S. federal income tax purposes, by reason of "extraordinary dividends" received with respect to the shares and, to the extent such basis would be reduced below zero, current recognition of income may be required. In order to qualify for the deduction, corporate shareholders must meet the minimum holding period requirement stated above with respect to their fund shares, taking into account any holding period reductions from certain hedging or other transactions or positions that diminish their risk of loss with respect to their fund shares, and, if they borrow to acquire or otherwise incur debt attributable to fund shares, they may be denied a portion of the dividends-received deduction. The entire dividend, including the otherwise deductible amount, will be included in determining the excess, if any, of a corporation's adjusted current earnings over its alternative minimum taxable income, which may increase a corporation's alternative minimum tax liability. The fund may be subject to withholding and other taxes imposed by foreign countries, including taxes on interest, dividends and capital gains with respect to its investments in those countries, which would, if imposed, reduce the yield on or return from those investments. Tax conventions between certain countries and the U.S. may reduce or eliminate such taxes in some cases. The fund does not expect to satisfy the requirements for passing through to its shareholders their pro rata shares of qualified foreign taxes paid by the fund, with the result that shareholders will not include such taxes in their gross incomes and will not be entitled to a tax deduction or credit for such taxes on their own tax returns. Shareholders that are exempt from U.S. federal income tax, such as retirement plans that are qualified under Section 401 of the Code, generally are not subject to U.S. federal income tax on fund dividends or distributions or on sales or exchanges of fund shares unless the acquisition of the fund shares was debt-financed. However, in the case of fund shares held through a non-qualified deferred compensation plan, fund dividends and distributions received by the plan and sales and exchanges of fund shares by the plan 57 generally are taxable to the employer sponsoring such plan in accordance with the U.S. federal income tax laws governing deferred compensation plans. A plan participant whose retirement plan invests in the fund, whether such plan is qualified or not, generally is not taxed on fund dividends or distributions received by the plan or on sales or exchanges of fund shares by the plan for U.S. federal income tax purposes. However, distributions to plan participants from a retirement plan account generally are taxable as ordinary income and different tax treatment, including penalties on certain excess contributions and deferrals, certain pre-retirement and post-retirement distributions and certain prohibited transactions, is accorded to accounts maintained as qualified retirement plans. Shareholders should consult their tax advisers for more information. Federal law requires that the fund withhold (as "backup withholding") 28% of reportable payments, including dividends, capital gain distributions and the proceeds of redemptions and exchanges or repurchases of fund shares, paid to shareholders who have not complied with IRS regulations. In order to avoid this withholding requirement, shareholders, other than certain exempt entities, must certify on their Account Applications, or on separate IRS Forms W-9, that the Social Security Number or other Taxpayer Identification Number they provide is their correct number and that they are not currently subject to backup withholding, or that they are exempt from backup withholding. The fund may nevertheless be required to backup withhold if it receives notice from the IRS or a broker that the number provided is incorrect or backup withholding is applicable as a result of previous underreporting of interest or dividend income. If, as anticipated, the fund continues to qualify as a regulated investment company under the Code, it will not be required to pay any Massachusetts income, corporate excise or franchise taxes or any Delaware corporation income tax. The description of certain federal tax provisions above relates only to U.S. federal income tax consequences for shareholders who are U.S. persons, i.e., U.S. citizens or residents or U.S. corporations, partnerships, trusts or estates, and who are subject to U.S. federal income tax and hold their shares as capital assets. Except as otherwise provided, this description does not address the special tax rules that may be applicable to particular types of investors, such as financial institutions, insurance companies, securities dealers, or tax-exempt or tax-deferred plans, accounts or entities. Investors other than U.S. persons may be subject to different U.S. federal income tax treatment, including a non-resident alien U.S. withholding tax at the rate of 30% or at a lower treaty rate on amounts treated as ordinary dividends from the fund (other than certain dividends derived from short-term capital gains and qualified interest income of the fund for taxable years of the fund commencing after December 31, 2004 and prior to January 1, 2008, provided that the fund chooses to make a specific designation relating to such dividends) and, unless an effective IRS Form W-8BEN, or other authorized withholding certificate is on file, to backup withholding at the rate of 28% on certain other payments from the fund. The fund does not expect to be a "U.S. real property holding corporation" as defined in section 897(c)(2) of the Code and, therefore, does not expect to be subject to look-through rules for gains from the sale or exchange of U.S. real property interests. If the fund were a U.S. real property holding corporation, certain distributions by the fund to non-U.S. shareholders would be subject to U.S. federal withholding tax at a rate of up to 35% and non-U.S. shareholders owning 5% or more of the fund within one year of certain distributions would be required to file a U.S. federal income tax return to report such gains.. Shareholders should consult their own tax advisers on these matters and on state, local, foreign, and other applicable tax laws. 58 17.

APPENDIX A--DESCRIPTION OF SHORT-TERM DEBT, CORPORATE BOND AND PREFERRED STOCK RATINGS Moody's Investors Service, Inc. ("Moody's") Prime Rating System Moody's short-term ratings are opinions of the ability of issuers to honor senior financial obligations and contracts. Such obligations generally have an original maturity not exceeding one year, unless explicitly noted. Moody's employs the following designations, all judged to be investment grade, to indicate the relative repayment ability of rated issuers: Prime-1: Issuers rated Prime-1 (or supporting institutions) have a superior ability for repayment of senior short-term debt obligations. Prime-1 repayment ability will often be evidenced by many of the following characteristics: Leading market positions in well-established industries. High rates of return on funds employed. Conservative capitalization structure with moderate reliance on debt and ample asset protection. Broad margins in earnings coverage of fixed financial charges and high internal cash generation. Well-established access to a range of financial markets and assured sources of alternate liquidity. Prime-2: Issuers (or supporting institutions) rated Prime-2 have a strong ability to repay senior short-term debt obligations. This will normally be evidenced by many of the characteristics cited above, but to a lesser degree. Earnings trends and coverage ratios, while sound, may be more subject to variation than is the case for Prime-2 securities. Capitalization characteristics, while still appropriate, may be more affected by external conditions. Ample alternate liquidity is maintained. Prime-3: Issuers (or supporting institutions) rated Prime-3 have an acceptable ability for repayment of senior short-term obligations. The effect of industry characteristics and market compositions may be more pronounced. Variability in earnings and profitability may result in changes in the level of debt-protection measurements and may require relatively high financial leverage. Adequate alternate liquidity is maintained. Not Prime: Issuers rated Not Prime do not fall within any of the Prime rating categories. In addition, in certain countries the prime rating may be modified by the issuer's or guarantor's senior unsecured long-term debt rating. Moody's Debt Ratings Aaa: Bonds and preferred stock which are rated Aaa are judged to be of the best quality. They carry the smallest degree of investment risk and are generally referred to as "gilt edged." Interest payments are protected by a large or by an exceptionally stable margin and principal is secure. While the various protective elements are likely to change, such changes as can be visualized are most unlikely to impair the fundamentally strong position of such issues. Aa: Bonds and preferred stock which are rated Aa are judged to be of high quality by all standards. Together with the Aaa group they comprise what are generally known as high-grade bonds. They are rated lower than the best bonds because margins of protection may not be as large as in Aaa securities or 65 fluctuation of protective elements may be of greater amplitude or there may be other elements present which make the long-term risk appear somewhat larger than the Aaa securities. A: Bonds and preferred stock which are rated A possess many favorable investment attributes and are to be considered as upper-medium-grade obligations. Factors giving security to principal and interest are considered adequate, but elements may be present which suggest a susceptibility to impairment some time in the future. Baa: Bonds and preferred stock which are rated Baa are considered as medium-grade obligations (i.e., they are neither highly protected nor poorly secured). Interest payments and principal security appear adequate for the present but certain protective elements may be lacking or may be characteristically unreliable over any great length of time. Such bonds lack outstanding investment characteristics and in fact have speculative characteristics as well. Ba: Bonds and preferred stock which are rated Ba are judged to have speculative elements; their future cannot be considered as well-assured. Often the protection of interest and principal payments may be very moderate, and thereby not well safeguarded during both good and bad times over the future. Uncertainty of position characterizes bonds in this class. B: Bonds and preferred stock which are rated B generally lack characteristics of the desirable investment. Assurance of interest and principal payments or of maintenance of other terms of the contract over any long period of time may be small. Caa: Bonds and preferred stock which are rated Caa are of poor standing. Such issues may be in default or there may be present elements of danger with respect to principal or interest. Ca: Bonds and preferred stock which are rated Ca represent obligations which are speculative in a high degree. Such issues are often in default or have other marked shortcomings. C: Bonds and preferred stock which are rated C are the lowest rated class of bonds, and issues so rated can be regarded as having extremely poor prospects of ever attaining any real investment standing. Moody's assigns ratings to individual debt securities issued from medium-term note (MTN) programs, in addition to indicating ratings to MTN programs themselves. Notes issued under MTN programs with such indicated ratings are rated at issuance at the rating applicable to all pari passu notes issued under the same program, at the program's relevant indicated rating, provided such notes do not exhibit any of the characteristics listed below. For notes with any of the following characteristics, the rating of the individual note may differ from the indicated rating of the program: 1) Notes containing features which link the cash flow and/or market value to the credit performance of any third party or parties. 2) Notes allowing for negative coupons, or negative principal. 3) Notes containing any provision which could obligate the investor to make any additional payments. Market participants must determine whether any particular note is rated, and if so, at what rating level. Note: Moody's applies numerical modifiers 1, 2, and 3 in each generic rating classification from Aa through Caa. The modifier 1 indicates that the obligation ranks in the higher end of its generic rating category; the modifier 2 indicates a mid-range ranking; and the modifier 3 indicates a ranking in the lower end of that generic rating category. 66 Standard & Poor's Short-Term Issue Credit Ratings A-1: A short-term obligation rated A-1 is rated in the highest category by Standard & Poor's. The obligor's capacity to meet its financial commitment on the obligation is strong. Within this category, certain obligations are designated with a plus sign (+). This indicates that the obligor's capacity to meet its financial commitment on these obligations is extremely strong. A-2: A short-term obligation rated A-2 is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher rating categories. However, the obligor's capacity to meet its financial commitment on the obligation is satisfactory. A-3: A short-term obligation rated A-3 exhibits adequate protection parameters. However, adverse economic conditions or changing circumstances are more likely to lead to a weakened capacity of the obligor to meet its financial commitment on the obligation. B: A short-term obligation rated B is regarded as having significant speculative characteristics. The obligor currently has the capacity to meet its financial commitment on the obligation; however, it faces major ongoing uncertainties which could lead to the obligor's inadequate capacity to meet its financial commitment on the obligation. C: A short-term obligation rated C is currently vulnerable to nonpayment and is dependent upon favorable business, financial, and economic conditions for the obligor to meet its financial commitment on the obligation. D: A short-term obligation rated D is in payment default. The D rating category is used when payments on an obligation are not made on the date due even if the applicable grace period has not expired, unless Standard & Poor's believes that such payments will be made during such grace period. The D rating also will be used upon the filing of a bankruptcy petition or the taking of a similar action if payments on an obligation are jeopardized. Standard & Poor's Long-Term Issue Credit Ratings Issue credit ratings are based, in varying degrees, on the following considerations: o Likelihood of payment-capacity and willingness of the obligor to meet its financial commitment on an obligation in accordance with the terms of the obligation; o Nature of and provisions of the obligation; o Protection afforded by, and relative position of, the obligation in the event of bankruptcy, reorganization, or other arrangement under the laws of bankruptcy and other laws affecting creditors' rights. The issue rating definitions are expressed in terms of default risk. As such, they pertain to senior obligations of an entity. Junior obligations are typically rated lower than senior obligations, to reflect the lower priority in bankruptcy, as noted above. (Such differentiation applies when an entity has both senior and subordinated obligations, secured and unsecured obligations, or operating company and holding company obligations.) Accordingly, in the case of junior debt, the rating may not conform exactly with the category definition. 67 AAA: An obligation rated AAA has the highest rating assigned by Standard & Poor's. The obligor's capacity to meet its financial commitment on the obligation is extremely strong. AA: An obligation rated AA differs from the highest rated obligations only in small degree. The obligor's capacity to meet its financial commitment on the obligation is very strong. A: An obligation rated A is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher rated categories. However, the obligor's capacity to meet its financial commitment on the obligation is still strong. BBB: An obligation rated BBB exhibits adequate protection parameters. However, adverse economic conditions or changing circumstances are more likely to lead to a weakened capacity of the obligor to meet its financial commitment on the obligation. Obligations rated BB, B, CCC, CC, and C are regarded as having significant speculative characteristics. BB indicates the least degree of speculation and C the highest. While such obligations will likely have some quality and protective characteristics, these may be outweighed by large uncertainties or major exposures to adverse conditions. BB: An obligation rated BB is less vulnerable to nonpayment than other speculative issues. However, it faces major ongoing uncertainties or exposure to adverse business, financial, or economic conditions which could lead to the obligor's inadequate capacity to meet its financial commitment on the obligation. B: An obligation rated B is more vulnerable to nonpayment than obligations rated BB, but the obligor currently has the capacity to meet its financial commitment on the obligation. Adverse business, financial, or economic conditions will likely impair the obligor's capacity or willingness to meet its financial commitment on the obligation. CCC: An obligation rated CCC is currently vulnerable to nonpayment, and is dependent upon favorable business, financial, and economic conditions for the obligor to meet its financial commitment on the obligation. In the event of adverse business, financial, or economic conditions, the obligor is not likely to have the capacity to meet its financial commitment on the obligation. CC: An obligation rated CC is currently highly vulnerable to nonpayment. C: A subordinated debt or preferred stock obligation rated C is currently highly vulnerable to nonpayment. The C rating may be used to cover a situation where a bankruptcy petition has been filed or similar action taken, but payments on this obligation are being continued. A C also will be assigned to a preferred stock issue in arrears on dividends or sinking fund payments, but that is currently paying. D: An obligation rated D is in payment default. The D rating category is used when payments on an obligation are not made on the date due even if the applicable grace period has not expired, unless Standard & Poor's believes that such payments will be made during such grace period. The D rating also will be used upon the filing of a bankruptcy petition or the taking of a similar action if payments on an obligation are jeopardized. Plus (+) or minus (-): The ratings from AA to CCC may be modified by the addition of a plus or minus sign to show relative standing within the major rating categories. 68 r: This symbol is attached to the ratings of instruments with significant noncredit risks. It highlights risks to principal or volatility of expected returns which are not addressed in the credit rating. N.R.: This indicates that no rating has been requested, that there is insufficient information on which to base a rating, or that Standard & Poor's does not rate a particular obligation as a matter of policy. Local Currency and Foreign Currency Risks Country risk considerations are a standard part of Standard & Poor's analysis for credit ratings on any issuer or issue. Currency of repayment is a key factor in this analysis. An obligor's capacity to repay foreign currency obligations may be lower than its capacity to repay obligations in its local currency due to the sovereign government's own relatively lower capacity to repay external versus domestic debt. These sovereign risk considerations are incorporated in the debt ratings assigned to specific issues. Foreign currency issuer ratings are also distinguished from local currency issuer ratings to identify those instances where sovereign risks make them different for the same issuer. The ratings indicated herein are believed to be the most recent ratings available at the date of this statement of additional information for the securities listed. Ratings are generally given to securities at the time of issuance. While the rating agencies may from time to time revise such ratings, they undertake no obligation to do so, and the ratings indicated do not necessarily represent ratings which will be given to these securities on the date of the fund's fiscal year-end. 69 21.

To satisfy its duty of loyalty, Pioneer must place its client's interests ahead of its own and must cast proxy votes in a manner consistent with the best interest of its clients. Pioneer will vote all proxies presented in a timely manner. The Proxy Voting Policies and Procedures are designed to complement Pioneer's investment policies and procedures regarding its general responsibility to monitor the performance and/or corporate events of companies that are issuers of securities held in accounts managed by Pioneer. Pioneer's Proxy Voting Policies summarize Pioneer's position on a number of issues solicited by companies held by Pioneer's clients. The policies are guidelines that provide a general indication on how Pioneer would vote but do not include all potential voting scenarios. Pioneer's Proxy Voting Procedures detail monitoring of voting, exception votes, and review of conflicts of interest and ensure that case-by-case votes are handled within the context of the overall guidelines (i.e. best interest of client). The overriding goal is that all proxies for US and non-US companies that are received promptly will be voted in accordance with Pioneer's policies or specific client instructions. All shares in a company held by Pioneer-managed accounts will be voted alike, unless a client has given us specific voting instructions on an issue or has not delegated authority to us or the Proxy Voting Oversight Group determines that the circumstances justify a different approach. Pioneer does not delegate the authority to vote proxies relating to its clients to any of its affiliates, which include other subsidiaries of UniCredito. Any questions about these policies and procedures should be directed to the Proxy Coordinator. Proxy Voting Procedures Proxy Voting Service Pioneer has engaged an independent proxy voting service to assist in the voting of proxies. The proxy voting service works with custodians to ensure that all proxy materials are received by the custodians and are processed in a timely fashion. To the extent applicable, the proxy voting service votes all proxies in accordance with the proxy voting policies established by Pioneer. The proxy voting service will refer proxy questions to the Proxy Coordinator (described below) for instructions under circumstances where: (1) the application of the proxy voting guidelines is unclear; (2) a particular proxy question is not covered by the guidelines; or (3) the guidelines call for specific instructions on a case-by-case basis. The proxy voting service is also requested to call to the Proxy Coordinator's attention specific proxy questions that, while governed by a guideline, appear to involve unusual or controversial issues. Pioneer reserves the 70 right to attend a meeting in person and may do so when it determines that the company or the matters to be voted on at the meeting are strategically important to its clients. Proxy Coordinator Pioneer's Director of Investment Operations (the "Proxy Coordinator") coordinates the voting, procedures and reporting of proxies on behalf of Pioneer's clients. The Proxy Coordinator will deal directly with the proxy voting service and, in the case of proxy questions referred by the proxy voting service, will solicit voting recommendations and instructions from the Director of Portfolio Management US or, to the extent applicable, investment sub-advisers. The Proxy Coordinator is responsible for ensuring that these questions and referrals are responded to in a timely fashion and for transmitting appropriate voting instructions to the proxy voting service. The Proxy Coordinator is responsible for verifying with the Compliance Department whether Pioneer's voting power is subject to any limitations or guidelines issued by the client (or in the case of an employee benefit plan, the plan's trustee or other fiduciaries). Referral Items From time to time, the proxy voting service will refer proxy questions to the Proxy Coordinator that are described by Pioneer's policy as to be voted on a case-by-case basis, that are not covered by Pioneer's guidelines or where Pioneer's guidelines may be unclear with respect to the matter to be voted on. Under such certain circumstances, the Proxy Coordinator will seek a written voting recommendation from the Director of Portfolio Management US. Any such recommendation will include: (i) the manner in which the proxies should be voted; (ii) the rationale underlying any such decision; and (iii) the disclosure of any contacts or communications made between Pioneer and any outside parties concerning the proxy proposal prior to the time that the voting instructions are provided. In addition, the Proxy Coordinator will ask the Compliance Department to review the question for any actual or apparent conflicts of interest as described below under "Conflicts of Interest." The Compliance Department will provide a "Conflicts of Interest Report," applying the criteria set forth below under "Conflicts of Interest," to the Proxy Coordinator summarizing the results of its review. In the absence of a conflict of interest, the Proxy Coordinator will vote in accordance with the recommendation of the Director of Portfolio Management US. If the matter presents a conflict of interest for Pioneer, then the Proxy Coordinator will refer the matter to the Proxy Voting Oversight Group for a decision. In general, when a conflict of interest is present, Pioneer will vote according to the recommendation of the Director of Portfolio Management US where such recommendation would go against Pioneer's interest or where the conflict is deemed to be immaterial. Pioneer will vote according to the recommendation of its proxy voting service when the conflict is deemed to be material and the Pioneer's internal vote recommendation would favor Pioneer's interest, unless a client specifically requests Pioneer to do otherwise. When making the final determination as to how to vote a proxy, the Proxy Voting Oversight Group will review the report from the Director of Portfolio Management US and the Conflicts of Interest Report issued by the Compliance Department. Conflicts of Interest A conflict of interest occurs when Pioneer's interests interfere, or appear to interfere with the interests of Pioneer's clients. Occasionally, Pioneer may have a conflict that can affect how its votes proxies. The conflict may be actual or perceived and may exist when the matter to be voted on concerns: o An affiliate of Pioneer, such as another company belonging to the UniCredito Italiano S.p.A. banking group (a "UniCredito Affiliate"); 71 o An issuer of a security for which Pioneer acts as a sponsor, advisor, manager, custodian, distributor, underwriter, broker, or other similar capacity (including those securities specifically declared by PGAM to present a conflict of interest for Pioneer); o An issuer of a security for which UniCredito has informed Pioneer that a UniCredito Affiliate acts as a sponsor, advisor, manager, custodian, distributor, underwriter, broker, or other similar capacity; or o A person with whom Pioneer (or any of its affiliates) has an existing, material contract or business relationship that was not entered into in the ordinary course of Pioneer's business. o Pioneer will abstain from voting with respect to companies directly or indirectly owned by UniCredito Italiano Group, unless otherwise directed by a client. In addition, Pioneer will inform PGAM Global Compliance and the PGAM Independent Directors before exercising such rights. Any associate involved in the proxy voting process with knowledge of any apparent or actual conflict of interest must disclose such conflict to the Proxy Coordinator and the Compliance Department. The Compliance Department will review each item referred to Pioneer to determine whether an actual or potential conflict of interest with Pioneer exists in connection with the proposal(s) to be voted upon. The review will be conducted by comparing the apparent parties affected by the proxy proposal being voted upon against the Compliance Department's internal list of interested persons and, for any matches found, evaluating the anticipated magnitude and possible probability of any conflict of interest being present. For each referral item, the determination regarding the presence or absence of any actual or potential conflict of interest will be documented in a Conflicts of Interest Report to the Proxy Coordinator. Securities Lending In conjunction with industry standards Proxies are not available to be voted when the shares are out on loan through either Pioneer's lending program or a client's managed security lending program. However, Pioneer will reserve the right to recall lent securities so that they may be voted according to the Pioneer's instructions. If a portfolio manager would like to vote a block of previously lent shares, the Proxy Coordinator will work with the portfolio manager and Investment Operations to recall the security, to the extent possible, to facilitate the vote on the entire block of shares. Share-Blocking "Share-blocking" is a market practice whereby shares are sent to a custodian (which may be different than the account custodian) for record keeping and voting at the general meeting. The shares are unavailable for sale or delivery until the end of the blocking period (typically the day after general meeting date). Pioneer will vote in those countries with "share-blocking." In the event a manager would like to sell a security with "share-blocking", the Proxy Coordinator will work with the Portfolio Manager and Investment Operations Department to recall the shares (as allowable within the market time-frame and practices) and/or communicate with executing brokerage firm. A list of countries with "share-blocking" is available from the Investment Operations Department upon request. Record Keeping The Proxy Coordinator shall ensure that Pioneer's proxy voting service: o Retains a copy of the proxy statement received (unless the proxy statement is available from the SEC's Electronic Data Gathering, Analysis, and Retrieval (EDGAR) system); o Retains a record of the vote cast; o Prepares Form N-PX for filing on behalf of each client that is a registered investment company; and 72 o Is able to promptly provide Pioneer with a copy of the voting record upon its request. The Proxy Coordinator shall ensure that for those votes that may require additional documentation (i.e. conflicts of interest, exception votes and case-by-case votes) the following records are maintained: o A record memorializing the basis for each referral vote cast; o A copy of any document created by Pioneer that was material in making the decision on how to vote the subject proxy; and o A copy of any conflict notice, conflict consent or any other written communication (including emails or other electronic communications) to or from the client (or in the case of an employee benefit plan, the plan's trustee or other fiduciaries) regarding the subject proxy vote cast by, or the vote recommendation of, Pioneer. Pioneer shall maintain the above records in the client's file for a period not less than ten (10) years. Disclosure Pioneer shall take reasonable measures to inform its clients of the process or procedures clients must follow to obtain information regarding how Pioneer voted with respect to assets held in their accounts. In addition, Pioneer shall describe to clients its proxy voting policies and procedures and will furnish a copy of its proxy voting policies and procedures upon request. This information may be provided to clients through Pioneer's Form ADV (Part II) disclosure, by separate notice to the client, or through Pioneer's website. Proxy Voting Oversight Group The members of the Proxy Voting Oversight Group are Pioneer's: Director of Portfolio Management US, Head of Investment Operations, and Director of Compliance. Other members of Pioneer will be invited to attend meetings and otherwise participate as necessary. The Head of Investment Operations will chair the Proxy Voting Oversight Group. The Proxy Voting Oversight Group is responsible for developing, evaluating, and changing (when necessary) Pioneer's Proxy Voting Policies and Procedures. The group meets at least annually to evaluate and review these policies and procedures and the services of its third-party proxy voting service. In addition, the Proxy Voting Oversight Group will meet as necessary to vote on referral items and address other business as necessary. Amendments Pioneer may not amend its Proxy Voting Policies And Procedures without the prior approval of the Proxy Voting Oversight Group and its corporate parent, Pioneer Global Asset Management S.p.A Proxy Voting Policies Pioneer's sole concern in voting proxies is the economic effect of the proposal on the value of portfolio holdings, considering both the short- and long-term impact. In many instances, Pioneer believes that supporting the company's strategy and voting "for" management's proposals builds portfolio value. In other cases, however, proposals set forth by management may have a negative effect on that value, while some shareholder proposals may hold the best prospects for enhancing it. Pioneer monitors developments in the proxy-voting arena and will revise this policy as needed. All proxies that are received promptly will be voted in accordance with the specific policies listed below. 73 All shares in a company held by Pioneer-managed accounts will be voted alike, unless a client has given us specific voting instructions on an issue or has not delegated authority to us. Proxy voting issues will be reviewed by Pioneer's Proxy Voting Oversight Group, which consists of the Director of Portfolio Management US, the Director of Investment Operations (the Proxy Coordinator), and the Director of Compliance. Pioneer has established Proxy Voting Procedures for identifying and reviewing conflicts of interest that may arise in the voting of proxies. Clients may request, at any time, a report on proxy votes for securities held in their portfolios and Pioneer is happy to discuss our proxy votes with company management. Pioneer retains a proxy voting service to provide research on proxy issues and to process proxy votes. Administrative While administrative items appear infrequently in U.S. issuer proxies, they are quite common in non-U.S. proxies. We will generally support these and similar management proposals: o Corporate name change. o A change of corporate headquarters. o Stock exchange listing. o Establishment of time and place of annual meeting. o Adjournment or postponement of annual meeting. o Acceptance/approval of financial statements. o Approval of dividend payments, dividend reinvestment plans and other dividend-related proposals. o Approval of minutes and other formalities. o Authorization of the transferring of reserves and allocation of income. o Amendments to authorized signatories. o Approval of accounting method changes or change in fiscal year-end. o Acceptance of labor agreements. o Appointment of internal auditors. Pioneer will vote on a case-by-case basis on other routine business; however, Pioneer will oppose any routine business proposal if insufficient information is presented in advance to allow Pioneer to judge the merit of the proposal. Pioneer has also instructed its proxy voting service to inform Pioneer of its analysis of any administrative items inconsistent, in its view, with supporting the value of Pioneer portfolio holdings so that Pioneer may consider and vote on those items on a case-by-case basis. 74 Auditors We normally vote for proposals to: o Ratify the auditors. We will consider a vote against if we are concerned about the auditors' independence or their past work for the company. Specifically, we will oppose the ratification of auditors and withhold votes from audit committee members if non-audit fees paid by the company to the auditing firm exceed the sum of audit fees plus audit-related fees plus permissible tax fees according to the disclosure categories proposed by the Securities and Exchange Commission. o Restore shareholder rights to ratify the auditors. We will normally oppose proposals that require companies to: o Seek bids from other auditors. o Rotate auditing firms, except where the rotation is statutorily required or where rotation would demonstrably strengthen financial disclosure. o Indemnify auditors. o Prohibit auditors from engaging in non-audit services for the company. Board of Directors On issues related to the board of directors, Pioneer normally supports management. We will, however, consider a vote against management in instances where corporate performance has been very poor or where the board appears to lack independence. General Board Issues Pioneer will vote for: o Audit, compensation and nominating committees composed of independent directors exclusively. o Indemnification for directors for actions taken in good faith in accordance with the business judgment rule. We will vote against proposals for broader indemnification. o Changes in board size that appear to have a legitimate business purpose and are not primarily for anti-takeover reasons. o Election of an honorary director. We will vote against: o Minimum stock ownership by directors. o Term limits for directors. Companies benefit from experienced directors, and shareholder control is better achieved through annual votes. o Requirements for union or special interest representation on the board. o Requirements to provide two candidates for each board seat. 75 We will vote on a case-by case basis on these issues: o Separate chairman and CEO positions. We will consider voting with shareholders on these issues in cases of poor corporate performance. Elections of Directors In uncontested elections of directors we will vote against: o Individual directors with absenteeism above 25% without valid reason. We support proposals that require disclosure of director attendance. o Insider directors and affiliated outsiders who sit on the audit, compensation, stock option or nominating committees. For the purposes of our policy, we accept the definition of affiliated directors provided by our proxy voting service. We will also vote against: o Directors who have failed to act on a takeover offer where the majority of shareholders have tendered their shares. o Directors who appear to lack independence or are associated with very poor corporate performance. We will vote on a case-by case basis on these issues: o Re-election of directors who have implemented or renewed a dead-hand or modified dead-hand poison pill (a "dead-hand poison pill" is a shareholder rights plan that may be altered only by incumbent or "dead " directors. These plans prevent a potential acquirer from disabling a poison pill by obtaining control of the board through a proxy vote). o Contested election of directors. o Prior to phase-in required by SEC, we would consider supporting election of a majority of independent directors in cases of poor performance. o Mandatory retirement policies. o Directors who have ignored a shareholder proposal that has been approved by shareholders for two consecutive years. Takeover-Related Measures Pioneer is generally opposed to proposals that may discourage takeover attempts. We believe that the potential for a takeover helps ensure that corporate performance remains high. Pioneer will vote for: o Cumulative voting. o Increase ability for shareholders to call special meetings. o Increase ability for shareholders to act by written consent. 76 o Restrictions on the ability to make greenmail payments. o Submitting rights plans to shareholder vote. o Rescinding shareholder rights plans ("poison pills"). o Opting out of the following state takeover statutes: o Control share acquisition statutes, which deny large holders voting rights on holdings over a specified threshold. o Control share cash-out provisions, which require large holders to acquire shares from other holders. o Freeze-out provisions, which impose a waiting period on large holders before they can attempt to gain control. o Stakeholder laws, which permit directors to consider interests of non-shareholder constituencies. o Disgorgement provisions, which require acquirers to disgorge profits on purchases made before gaining control. o Fair price provisions. o Authorization of shareholder rights plans. o Labor protection provisions. o Mandatory classified boards. We will vote on a case-by-case basis on the following issues: o Fair price provisions. We will vote against provisions requiring supermajority votes to approve takeovers. We will also consider voting against proposals that require a supermajority vote to repeal or amend the provision. Finally, we will consider the mechanism used to determine the fair price; we are generally opposed to complicated formulas or requirements to pay a premium. o Opting out of state takeover statutes regarding fair price provisions. We will use the criteria used for fair price provisions in general to determine our vote on this issue. o Proposals that allow shareholders to nominate directors. We will vote against: o Classified boards, except in the case of closed-end mutual funds. o Limiting shareholder ability to remove or appoint directors. We will support proposals to restore shareholder authority in this area. We will review on a case-by-case basis proposals that authorize the board to make interim appointments. o Classes of shares with unequal voting rights. 77 o Supermajority vote requirements. o Severance packages ("golden" and "tin" parachutes). We will support proposals to put these packages to shareholder vote. o Reimbursement of dissident proxy solicitation expenses. While we ordinarily support measures that encourage takeover bids, we believe that management should have full control over corporate funds. o Extension of advance notice requirements for shareholder proposals. o Granting board authority normally retained by shareholders (e.g., amend charter, set board size). o Shareholder rights plans ("poison pills"). These plans generally allow shareholders to buy additional shares at a below-market price in the event of a change in control and may deter some bids. Capital Structure Managements need considerable flexibility in determining the company's financial structure, and Pioneer normally supports managements' proposals in this area. We will, however, reject proposals that impose high barriers to potential takeovers. Pioneer will vote for: o Changes in par value. o Reverse splits, if accompanied by a reduction in number of shares. o Share repurchase programs, if all shareholders may participate on equal terms. o Bond issuance. o Increases in "ordinary" preferred stock. o Proposals to have blank-check common stock placements (other than shares issued in the normal course of business) submitted for shareholder approval. o Cancellation of company treasury shares. We will vote on a case-by-case basis on the following issues: o Reverse splits not accompanied by a reduction in number of shares, considering the risk of delisting. o Increase in authorized common stock. We will make a determination considering, among other factors: o Number of shares currently available for issuance; o Size of requested increase (we would normally approve increases of up to 100% of current authorization); o Proposed use of the additional shares; and 78 o Potential consequences of a failure to increase the number of shares outstanding (e.g., delisting or bankruptcy). o Blank-check preferred. We will normally oppose issuance of a new class of blank-check preferred, but may approve an increase in a class already outstanding if the company has demonstrated that it uses this flexibility appropriately. o Proposals to submit private placements to shareholder vote. o Other financing plans. We will vote against preemptive rights that we believe limit a company's financing flexibility. Compensation Pioneer supports compensation plans that link pay to shareholder returns and believes that management has the best understanding of the level of compensation needed to attract and retain qualified people. At the same time, stock-related compensation plans have a significant economic impact and a direct effect on the balance sheet. Therefore, while we do not want to micromanage a company's compensation programs, we will place limits on the potential dilution these plans may impose. Pioneer will vote for: o 401(k) benefit plans. o Employee stock ownership plans (ESOPs), as long as shares allocated to ESOPs are less than 5% of outstanding shares. Larger blocks of stock in ESOPs can serve as a takeover defense. We will support proposals to submit ESOPs to shareholder vote. o Various issues related to the Omnibus Budget and Reconciliation Act of 1993 (OBRA), including: o Amendments to performance plans to conform with OBRA; o Caps on annual grants or amendments of administrative features; o Adding performance goals; and o Cash or cash-and-stock bonus plans. o Establish a process to link pay, including stock-option grants, to performance, leaving specifics of implementation to the company. o Require that option repricings be submitted to shareholders. o Require the expensing of stock-option awards. o Require reporting of executive retirement benefits (deferred compensation, split-dollar life insurance, SERPs, and pension benefits). o Employee stock purchase plans where the purchase price is equal to at least 85% of the market price, where the offering period is no greater than 27 months and where potential dilution (as defined below) is no greater than 10%. 79 We will vote on a case-by-case basis on the following issues: o Executive and director stock-related compensation plans. We will consider the following factors when reviewing these plans: o The program must be of a reasonable size. We will approve plans where the combined employee and director plans together would generate less than 15% dilution. We will reject plans with 15% or more potential dilution. Dilution = (A + B + C) / (A + B + C + D), where A = Shares reserved for plan/amendment, B = Shares available under continuing plans, C = Shares granted but unexercised and D = Shares outstanding. o The plan must not: o Explicitly permit unlimited option repricing authority or that have repriced in the past without shareholder approval. o Be a self-replenishing "evergreen" plan, plans that grant discount options and tax offset payments. o We are generally in favor of proposals that increase participation beyond executives. o We generally support proposals asking companies to adopt rigorous vesting provisions for stock option plans such as those that vest incrementally over, at least, a three- or four-year period with a pro rata portion of the shares becoming exercisable on an annual basis following grant date. o We generally support proposals asking companies to disclose their window period policies for stock transactions. Window period policies ensure that employees do not exercise options based on insider information contemporaneous with quarterly earnings releases and other material corporate announcements. o We generally support proposals asking companies to adopt stock holding periods for their executives. o All other employee stock purchase plans. o All other compensation-related proposals, including deferred compensation plans, employment agreements, loan guarantee programs and retirement plans. o All other proposals regarding stock compensation plans, including extending the life of a plan, changing vesting restrictions, repricing options, lengthening exercise periods or accelerating distribution of awards and pyramiding and cashless exercise programs. We will vote against: o Pensions for non-employee directors. We believe these retirement plans reduce director objectivity. o Elimination of stock option plans. 80 We will vote on a case-by case basis on these issues: o Limits on executive and director pay. o Stock in lieu of cash compensation for directors. Corporate Governance Pioneer will vote for: o Confidential Voting. o Equal access provisions, which allow shareholders to contribute their opinion to proxy materials. o Proposals requiring directors to disclose their ownership of shares in the company. We will vote on a case-by-case basis on the following issues: o Change in the state of incorporation. We will support reincorporations supported by valid business reasons. We will oppose those that appear to be solely for the purpose of strengthening takeover defenses. o Bundled proposals. We will evaluate the overall impact of the proposal. o Adopting or amending the charter, bylaws or articles of association. o Shareholder appraisal rights, which allow shareholders to demand judicial review of an acquisition price. We will vote against: o Shareholder advisory committees. While management should solicit shareholder input, we prefer to leave the method of doing so to management's discretion. o Limitations on stock ownership or voting rights. o Reduction in share ownership disclosure guidelines. Mergers and Restructurings Pioneer will vote on the following and similar issues on a case-by-case basis: o Mergers and acquisitions. o Corporate restructurings, including spin-offs, liquidations, asset sales, joint ventures, conversions to holding company and conversions to self-managed REIT structure. o Debt restructurings. o Conversion of securities. o Issuance of shares to facilitate a merger. 81 o Private placements, warrants, convertible debentures. o Proposals requiring management to inform shareholders of merger opportunities. We will normally vote against shareholder proposals requiring that the company be put up for sale. Mutual Funds Many of our portfolios may invest in shares of closed-end mutual funds or exchange-traded funds. The non-corporate structure of these investments raises several unique proxy voting issues. Pioneer will vote for: o Establishment of new classes or series of shares. o Establishment of a master-feeder structure. Pioneer will vote on a case-by-case on: o Changes in investment policy. We will normally support changes that do not affect the investment objective or overall risk level of the fund. We will examine more fundamental changes on a case-by-case basis. o Approval of new or amended advisory contracts. o Changes from closed-end to open-end format. o Authorization for, or increase in, preferred shares. o Disposition of assets, termination, liquidation, or mergers. o Classified boards of closed-end mutual funds, but will typically support such proposals. Social Issues Pioneer will abstain on stockholder proposals calling for greater disclosure of corporate activities with regard to social issues. "Social Issues" may generally be described as shareholder proposals for a company to: o Conduct studies regarding certain issues of public concern and interest; o Study the feasibility of the company taking certain actions with regard to such issues; or o Take specific action, including ceasing certain behavior and adopting company standards and principles, in relation to issues of public concern and interest. We believe these issues are important and should receive management attention. Pioneer will vote against proposals calling for substantial changes in the company's business or activities. We will also normally vote against proposals with regard to contributions, believing that management should control the routine disbursement of funds. 82
