Job conditions are strengthening as well: by mid-year, the unemployment rate had fallen to 5.0% for the first time since September 11, 2001. Retail sales trends - - apart from automobiles - were upbeat as sunnier employment prospects sent consumers to the malls. And with the economy expanding, corporate profits have been moving ahead smartly. But equity investors were unconvinced by this evidence and instead brooded about the possibility of slowing growth later in the year. For one thing, expectations were for a moderating pace of profit growth. For another, the Federal Reserve Board has raised short-term interest rates nine times. And some areas of the economy are feeling the impact of record high energy prices. So investors were lukewarm toward stocks, with modest losses in the S&P 500 Stock Index and the Dow Jones Industrials the result. The technology-heavy NASDAQ Composite also slid, as did small-company stocks, as measured by the Russell 2000 Index. Value stocks, viewed as less vulnerable to declines in a less robust economy, held up better than growth. Corporate bonds felt the sting of ratings downgrades in the automobile sector. Treasury issues fared better, as yields fell and prices rose among intermediate and longer-term issues, which were little affected by rising short-term rates. Low long-term yields may signal investor confidence that the Fed will succeed in dousing inflationary fires; they also brought more affordable mortgages, further boosting home construction. Municipal revenue bonds edged upward as healthier economic conditions bolstered tax collections. The dollar's rebound positively affected foreign markets. Europe's stock markets performed better than business and political conditions might suggest, and Japan's market inched higher. Pioneer's analysts believe that, although the rate of growth may slow, carefully selected, good quality stocks and bonds have the potential to deliver solid results. Our global investment experts are well positioned to discover what we believe are attractive opportunities in the world's markets. Large or small? Bonds or stocks? Domestic or international? Just what your mix of investments should be isn't a question to be taken lightly. Much of your long-term return will depend on the kinds of investments you own, not just the individual items in your portfolio. For an analysis of your holdings and some ideas to help bring your investments in line with your aspirations, talk to your financial professional.

Investment return and principal value will fluctuate, and shares, when redeemed, may be worth more or less than their original cost. The performance of Class R shares for the period prior to the commencement of operations of Class R shares on April 1, 2003 is based on the performance of Class A shares, reduced to reflect the higher distribution and service fees of Class R shares. For the period after April 1, 2003, the actual performance of Class R shares is reflected, which performance may be influenced by the smaller asset size of Class R shares compared to Class A shares. Class R shares are not subject to sales charges and are available for limited groups of eligible investors, including institutional investors. All results are historical and assume the reinvestment of dividends and capital gains. Other share classes are available for which performance and expenses will differ.

Investment return and principal value will fluctuate, and shares, when redeemed, may be worth more or less than their original cost. Performance for periods prior to the inception of Class Y shares reflects the NAV performance of the Fund's A shares. The performance does not reflect differences in expenses, including the Rule 12b-1 fees applicable to A shares. Since fees for Class A shares are generally higher than those of Class Y shares, the performance shown for Class Y shares prior to their inception would have been higher. Class A shares are used as a proxy through 4/30/98. Class Y shares are not subject to sales charges and are available for limited groups of eligible investors, including institutional investors. All results are historical and assume the reinvestment of dividends and capital gains. Other share classes are available for which performance and expenses will differ. Performance results reflect any applicable expense waivers in effect during the periods shown. Without such waivers Fund performance would be lower. Waivers may not be in effect for all funds.

This example is intended to help you understand your ongoing expenses (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 at the beginning of the Fund's latest six-month period and held throughout the six months. Using the Tables Actual Expenses The first table below provides information about actual account values and actual expenses. You may use the information in this table, together with the amount you invested, to estimate the expenses that you paid over the period as follows: 1. Divide your account value by $1,000 Example: an $8,600 account value [divided by] $1,000 = 8.6 2. Multiply the result in (1) above by the corresponding share class's number in the third row under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. Expenses Paid on a $1,000 Investment in Pioneer Growth Shares Based on actual returns from January 1, 2005 through June 30, 2005 Investor Share Class A B C Class R Y - ---------------------------------------------------------------------------------------------------------- Beginning Account Value $1,000.00 $1,000.00 $1,000.00 $1,000.00 $1,000.00 $1,000.00 On 1/1/05 Ending Account Value $ 977.70 $ 973.00 $ 973.30 $ 960.90 $ 976.90 $ 981.10 On 6/30/05 Expenses Paid During Period* $ 6.77 $ 11.30 $ 10.72 $ 4.28 $ 7.65 $ 3.44 * Expenses are equal to the Fund's annualized expense ratio of 1.38%, 2.31%, 2.19%, 1.56%, 0.70%, and 0.88%, for Class A, Class B, Class C, Class R, Class Y and Investor Class shares, respectively, multiplied by the average account value over the period, multiplied by 181/365 (to reflect the one-half year period). 10 Pioneer Growth Shares - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- Hypothetical Example for Comparison Purposes The table below provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the tables are meant to highlight your ongoing costs only and do not reflect any transaction costs, such as sales charges (loads) that are charged at the time of the transaction. Therefore, the table below is useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds. In addition, if these transaction costs were included, your costs would have been higher.

However, the comeback was not sufficient to avoid negative results for growth stocks for the six months ended June 30, 2005. In the following interview, Christopher Galizio discusses the factors that affected the performance of Pioneer Growth Shares during the six months ended June 30, 2005. Mr. Galizio is one of the co-managers responsible for day-to-day portfolio management of the Fund. Q: How did the Fund perform during the six months ended June 30, 2005? A: Performance slightly lagged that of the large-cap growth universe, principally because of poor results from a few holdings. For the first six months of 2005, the Fund's Class A shares had a total return at net asset value of -2.23%. During the same six months, the Russell 1000 Growth Index returned -1.72%, while the average return of the 670 funds in Lipper's Large Cap Growth Fund category was -1.75%.

The performance data quoted represents past performance, which is no guarantee of future results. Investment return and principal value will fluctuate, and shares, when redeemed, may be worth more or less than their original cost. Q: What were the principal factors affecting the Fund's results for the period? A: We made good sector allocations during the six months, helping to support Fund performance. We began 2005 with an emphasis on the cyclical sectors, notably the materials, industrials and energy areas. We saw that the economy was continuing to recover and a number of shortages were occurring in commodity markets, including copper. After these stocks rallied in the early months of the year, we took profits and reduced our positions substantially, even eliminating the Fund's materials investments. We believed the share prices of many of these companies had gone higher than we thought the corporations' values merited, and we decided to sell into strong demand. We were concerned that market interest rates - which had been declining despite the tightening policies of 12 Pioneer Growth Shares - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- the U.S. Federal Reserve Board - finally would begin to rise, adversely affecting cyclical stocks. Our worry about the risk of higher interest rates also prompted us to reduce our investments in consumer discretionary stocks, especially retailers. As we did this, we moved from cyclical stocks into other growth stocks, including information technology and health care. Both those sectors went from being underweighted (relative to the Fund's benchmark) to being emphasized over the course of the six months. In general, we believed it was time to move into companies with long-term growth prospects not dependent on cyclical movements in the economy or in commodity prices or interest rates. As we added to our information technology investments, we established positions in leading technology companies, such as Qualcomm and Cisco Systems. Q: What were some of the individual investments that helped support performance? A: Our investment in Texas Instruments was a major help to performance as it appreciated significantly with improved earnings prospects of its semiconductors and wireless phones and the introduction of a new generation of wireless telecommunications technology. Two of our best decisions were to avoid or de-emphasize major companies that were significant parts of the Russell 1000 Growth Index. We completely avoided any IBM stock, which declined by 20% during the six months. We also limited exposure to Internet auction company eBay, whose growth slowed and revenues declined in the face of new competition. eBay's stock declined 41% over the period. Two generic drug manufacturers turned in stellar performance for the period. Both IVAX and Endo Pharmaceutical rose with the improving outlook for generic manufacturers as several major drugs were scheduled to lose their patent protection in the near future. Both firms also had company-specific issues that gave their share prices extra support. IVAX received FDA approval of a new technology for inhalers for asthma patients that does not pose a danger to the ozone layer, while Endo won a court case challenging another company's claimed patent for the pain reliever oxycontin. 13 Pioneer Growth Shares - -------------------------------------------------------------------------------- PORTFOLIO MANAGEMENT DISCUSSION 6/30/05 (continued) - -------------------------------------------------------------------------------- Other strong performers included copper miners Phelps Dodge and Freeport-McMoRan, both of which we sold before the period ended, Altria Group, which won a court fight in a tobacco liability suit in which it was a defendant, and Hewlett-Packard, which gained on news of the appointment of a new chief executive. Q: What were some of the investments that held back performance? A: The biggest disappointment was Avaya, the producer of enterprise telephone systems for large corporations and other major institutions, whose stock price declined by 50%. Avaya offers large enterprises both traditional phone equipment as well as a newer technology that helps institutions transition to Internet-based phone systems. However, sales of the traditional equipment lagged, while the new technology failed to meet expectations. Despite the disappointment, we have retained the position, as the stock price has become very inexpensive and we still think the company has potential for significant earnings improvement. We also continue to own another notable detractor, information technology consulting company Accenture. The company reported disappointing earnings because one of its major contracts produced lower revenues than had been anticipated. However, we think this was a short-term problem and that the company has the potential to recover. Another disappointment was American International Group, the giant insurer, whose stock price plummeted in the midst of an SEC investigation into its finances that resulted in the forced resignation of its long-time chief executive. Not owning Intel was another decision that detracted from results. We did not view Intel, which produces 80% of the semiconductors for personal computers, as a true growth stock. However, the stock rose by 15% for the six months as the company successfully drove down its costs and improved its profitability. Similarly, not owning Pfizer, Johnson & Johnson and Genentech, all major companies in the health care sector, held back performance as all three did well. 14 Pioneer Growth Shares - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- Q: What is your outlook for the coming months? A: We believe the best opportunities will come from investments in secular, or long-term, growth companies, that are less sensitive to interest rates and the business cycle than are cyclical companies. We think interest rates are very low and due to start rising, while oil and basic materials prices may be vulnerable to price corrections. We have seen particular value in the information technology and health care companies, which have the potential to produce more consistent earnings.

The accompanying notes are an integral part of these financial statements 31 Pioneer Growth Shares - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 6/30/05 (unaudited) - -------------------------------------------------------------------------------- 1. Organization and Significant Accounting Policies Pioneer Growth Shares (the Fund) is a Delaware statutory trust registered under the Investment Company Act of 1940 as a diversified, open-end management investment company. The investment objective of the Fund is to seek appreciation of capital. The Trustees have authorized the issuance of six classes of shares of the Fund. The Fund offers six classes of shares designated as Class A, Class B, Class C, Investor Class, Class R and Class Y shares. Class R shares were first publicly offered on April 1, 2003. Investor Class shares were first issued on December 10, 2004. The Fund is not offering additional Investor Class shares except in connection with the reinvestment of dividends on the Fund's outstanding Investor Class shares. Each class of shares represents an interest in the same portfolio of investments of the Fund and has equal rights to voting, redemptions, dividends and liquidation, except that each class of shares can bear different transfer agent and distribution fees and has exclusive voting rights with respect to the distribution plans that have been adopted by Class A, Class B, Class C and Class R shareowners, respectively. There is no distribution plan for Class Y and Investor Class shares. The Fund's financial statements have been prepared in conformity with U.S. generally accepted accounting principles that require the management of the Fund to, among other things, make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of income, expenses and gains and losses on investments during the reporting year. Actual results could differ from those estimates. The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements, which are consistent with those policies generally accepted in the investment company industry: A. Security Valuation Security transactions are recorded as of trade date. The net asset value of the Fund is computed once daily, on each day the New York Stock Exchange (NYSE) is open, as of the close of regular trading on the NYSE. In computing the net asset value, securities are valued at the last sale price on the principal exchange where they are traded. Securities that have not traded on the date of valuation, or securities for which sale prices are not generally reported, are 32 Pioneer Growth Shares - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- valued at the mean between the last bid and asked prices. Securities for which market quotations are not readily available are valued at their fair values as determined by, or under the direction of, the Board of Trustees. Trading in foreign securities is substantially completed each day at various times prior to the close of the NYSE. The values of such securities used in computing the net asset value of the Fund's shares are determined as of such times. The Fund also may use the fair value of a security, including a non-U.S. security, when the closing market price on the principal exchange where the security is traded no longer reflects the value of the security. At June 30, 2005 there were no securities fair valued. Temporary cash investments are valued at amortized cost. Dividend income is recorded on the ex-dividend date except that certain dividends from foreign securities where the ex-dividend date may have passed are recorded as soon as the Fund becomes aware of the ex-dividend data in exercise of reasonable diligence. Interest income is recorded on the accrual basis. Dividend and interest income are reported net of unrecoverable foreign taxes withheld at the applicable country rates. Gains and losses on sales of investments are calculated on the identified cost method for both financial reporting and federal income tax purposes. B. Futures Contracts The Fund may enter into futures transactions to hedge against changes in interest rates, securities prices, and currency rates or to seek to increase total return. Upon entering into a futures contract, the Fund is required to deposit with a broker an amount of cash or securities equal to the minimum "initial margin" requirements of the associated futures exchange. Subsequent payments on futures contracts ("variation margin") are paid or received by the Fund, depending on the daily fluctuation in the value of the contracts, and are recorded by the Fund as unrealized gains or losses. When the contract is closed, the Fund realizes a gain or loss equal to the difference between the opening and closing value of the contract. The use of futures contracts involves, to varying degrees, elements of market risk which may exceed the amounts recognized by the Fund. Changes in value of the contracts may not directly correlate to the changes in value of the underlying securities. These risks may decrease the effectiveness of the Fund's hedging 33 Pioneer Growth Shares - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 6/30/05 (unaudited) (continued) - -------------------------------------------------------------------------------- strategies and potentially result in a loss. At June 30, 2005 there were no open futures contracts. C. Federal Income Taxes It is the Fund's policy to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its taxable income and net realized capital gains, if any, to its shareowners. Therefore, no federal income tax provision is required. The amounts and characterizations of distributions to shareowners for financial reporting purposes are determined in accordance with federal income tax rules. Therefore, the sources of the Fund's distributions may be shown in the accompanying financial statements as either from or in excess of net investment income or net realized gain on investment transactions, or from paid-in capital, depending on the type of book/tax differences that may exist. The tax character of current year distributions paid will be determined at the end of the current fiscal year. The tax character of distributions paid during the year ended December 31, 2004 was as follows: - ------------------------------------------------- 2004 - ------------------------------------------------- Distributions paid from: Ordinary income $352,043 Long-term capital gain - -------- Total $352,043 -------- - ------------------------------------------------- The following shows the components of accumulated losses on a federal income tax basis at December 31, 2004. - ------------------------------------------------- 2004 - ------------------------------------------------- Undistributed ordinary income $ 72,875 Capital loss carryforward (555,071,293) Post October loss deferred (8,291,896) Unrealized appreciation 40,453,674 ------------- Total $(522,836,640) ------------- - ------------------------------------------------- 34 Pioneer Growth Shares - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- The difference between book basis and tax basis unrealized appre ciation is attributable to the tax deferral of losses on wash sales. D. Fund Shares The Fund records sales and repurchases of its shares as of trade date. Pioneer Funds Distributor, Inc. (PFD), the principal underwriter for the Fund and a wholly owned indirect subsidiary of UniCredito Italiano S.p.A (UniCredito Italiano), earned $53,747 in underwriting commissions on the sale of Class A shares for the six months ended June 30, 2005. E. Class Allocations Distribution fees are calculated based on the average daily net asset value attributable to Class A, Class B, Class C and Class R shares of the Fund, respectively (see Note 4). Class Y and Investor Class shares are not subject to a distribution plan. Shareowners of each class share all expenses and fees paid to the transfer agent, Pioneer Investment Management Shareholder Services, Inc. (PIMSS), for its services, which are allocated based on the number of accounts in each class and the ratable allocation of related out-of-pocket expenses (see Note 3). Income, common expenses and realized and unrealized gains and losses are calculated at the Fund level and allocated daily to each class of shares based on their respective percentage of adjusted net assets at the beginning of the day. Distributions to shareowners are recorded as of the ex-dividend date. Distributions paid by the Fund with respect to each class of shares are calculated in the same manner, at the same time, and in the same amount, except that Class A, Class B, Class C, Investor Class, Class R and Class Y shares can bear different transfer agent and distribution fees. F. Securities Lending The Fund lends securities in the portfolio to certain broker-dealers or other institutional investors, with the Fund's custodian acting as the lending agent. When entering into a loan, the Fund receives collateral, which is maintained by the custodian and earns income in the form of negotiated lenders' fees. The Fund also continues to receive interest or payments in lieu of dividends on the securities loaned. Gain or loss on the fair value of the loaned securities that may occur during the term of the loan will be for account of the 35 Pioneer Growth Shares - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 6/30/05 (unaudited) (continued) - -------------------------------------------------------------------------------- Fund. The loans are secured by collateral of at least 102%, at all times, of the fair value of the securities loaned. The amount of the collateral will be adjusted daily to reflect any price fluctuation in the value of the loaned securities. The Fund has the right under the lending agreements to recover the securities from the borrower on demand. The Fund invests cash collateral in the Securities Lending Investment Fund, which is managed by Brown Brothers Harriman & Co., the Fund's custodian. G. Repurchase Agreements With respect to repurchase agreements entered into by the Fund, the value of the underlying securities (collateral), including accrued interest received from counterparties, is required to be at least equal to or in excess of the value of the repurchase agreement at the time of purchase. The collateral for all repurchase agreements is held in safekeeping in the customer-only account of the Fund's custodian, or subcustodians. The Fund's investment adviser, Pioneer Investment Management, Inc. (PIM), is responsible for determining that the value of the collateral remains at least equal to the repurchase price. 2. Management Agreement PIM, a wholly owned indirect subsidiary of UniCredito Italiano, manages the Fund's portfolio. PIM receives a basic fee that is calculated daily at the annual rate of 0.70% of the Fund's average daily net assets up to $500 million; 0.65% of the next $500 million; and 0.625% of the excess over $1 billion. The basic fee is subject to a performance adjustment up to a maximum of +/-0.10% based on the Fund's investment performance as compared with the Russell 1000 Growth Index over a rolling 36-month period. In addition, the fee is further limited to a maximum annualized rate adjustment of +/-0.10% (a "ceiling" and a "floor"). Effective August 1, 2004, PIM commenced a voluntary waiver of the minimum fee provision (the "floor"), but may reimpose it in the future. Pursuant to a shareowner vote on April 17, 2003, the benchmark index was changed from the Russell 1000 Index effective May 1, 2003; however, the Russell 1000 Index will be used for monthly periods prior to May 1, 2003 until it is eventually phased out. For the six months ended June 30, 2005, the aggregate performance adjustment resulted in a decrease to the basic fee of $256,428 and the management fee was equivalent to 0.61% of the average daily net assets. 36 Pioneer Growth Shares - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- Through December 10, 2006, PIM has agreed not to impose all or a portion of its management fee and to assume other operating expenses (excluding taxes, commissions, interest and extraordinary expenses) of the Fund to the extent necessary to limit Investor Class expenses to 1.15% of the average daily net assets attributable to Investor Class shares. In addition, under the management and administrative agreements, certain other services and costs, including accounting, regulatory reporting, and insurance premiums, are paid by the Fund. At June 30, 2005, $28,404 was payable to PIM related to management fees, administrative costs and certain other services and is included in due to affiliates. 3. Transfer Agent PIMSS, a wholly owned indirect subsidiary of UniCredito Italiano, provides substantially all transfer agent and shareowner services to the Fund at negotiated rates. Included in due to affiliates is $527,076 in transfer agent fees payable to PIMSS at June 30, 2005. 4. Distribution and Service Plans The Fund adopted a Plan of Distribution for each class of shares (Class A Plan, Class B Plan, Class C Plan, and Class R Plan) in accordance with Rule 12b-1 of the Investment Company Act of 1940. Pursuant to the Class A Plan, the Fund pays PFD a service fee of up to 0.25% of the average daily net assets attributable to Class A shares in reimbursement of its actual expenditures to finance activities primarily intended to result in the sale of Class A shares. Pursuant to the Class B Plan and the Class C Plan, the Fund pays PFD 1.00% of the average daily net assets attributable to each class of shares. The fee consists of a 0.25% service fee and a 0.75% distribution fee paid as compensation for personal services and/or account maintenance services or distribution services with regard to Class B and Class C shares. Pursuant to the Class R Plan, the Fund pays PFD 0.50% of the average daily net assets attributable to Class R shares for distribution services. Included in due to affiliates is $8,003 in distribution fees payable to PFD at June 30, 2005. The Fund also has adopted a separate service plan for Class R shares (Service Plan). The Service Plan authorizes the Fund to pay securities dealers, plan administrators or other services organizations that agree to provide certain services to retirement plans or plan participants holding shares of the 37 Pioneer Growth Shares - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 6/30/05 (unaudited) (continued) - -------------------------------------------------------------------------------- Fund a service fee of up to 0.25% of the Fund's average daily net assets attributable to Class R shares held by such plans. In addition, redemptions of each class of shares (except Class Y and Investor Class shares) may be subject to a contingent deferred sales charge (CDSC). Effective February 1, 2004, a CDSC of 1.00% may be imposed on redemptions of certain net asset value purchases of Class A shares within 18 months of purchase (12 months for shares purchased prior to February 1, 2004). Effective December 1, 2004, Class B shares that are redeemed within five years of purchase are subject to a CDSC at declining rates beginning at 4.00%, based on the lower of cost or market value of shares being redeemed. Shares purchased prior to December 1, 2004 remain subject to the CDSC in effect at the time those shares were purchased. Redemptions of Class C shares within one year of purchase are subject to a CDSC of 1.00%. Redemptions of Class R shares within 18 months of purchase were subject to a CDSC of 1.00%. Effective July 1, 2004, the CDSC on Class R shares was eliminated. Proceeds from the CDSCs are paid to PFD. For the six months ended June 30, 2005, CDSCs in the amount of $126,700 were paid to PFD. 5. Expense Offset Arrangements The Fund has entered into certain expense offset arrangements with PIMSS resulting in a reduction in the Fund's total expenses due to interest earned on cash held by PIMSS. For the six months ended June 30, 2005, the Fund's expenses were reduced by $30,655 under such arrangements. 6. Line Of Credit Facility The Fund, along with certain others in the Pioneer Family of Funds (the Funds), collectively participate in a $50 million committed, unsecured revolving line of credit facility. Borrowings are used solely for temporary or emergency purposes. The Fund may borrow up to the lesser of $50 million or the limits set by its prospectus for borrowings. Interest on collective borrowings is payable at the Federal Funds Rate plus 1/2% on an annualized basis. The Funds pay an annual commitment fee for this facility. The commitment fee is allocated among such Funds based on their respective borrowing limits. For the six months ended June 30, 2005, the Fund had no borrowings under this agreement. 38 Pioneer Growth Shares - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- 7. Merger Information On December 8, 2004, beneficial owners of Safeco Large-Cap Growth Fund (one of the Series that comprised the Safeco Common Stock Trust) approved a proposed Agreement and Plan of Reorganization that provided for the merger listed below. This tax-free reorganization was accomplished on December 10, 2004, by exchanging all of Safeco's net assets for the Fund's Investor Class shares, based on Class A shares' ending net asset value. The following charts show the details of the reorganizations as of that closing date ("Closing Date"): - -------------------------------------------------------------------------------- Safeco Pioneer Pioneer Large-Cap Growth Shares Growth Shares Growth Fund (Post- (Pre-Reorganization) (Pre-Reorganization) Reorganization) - ------------------------------------------------------------------------------------------- Net Assets $696,269,073 $6,560,837 $702,829,910 Shares Outstanding 60,757,867 679,972 61,315,761 Investor Shares Issued - - 557,894 - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- Unrealized Appreciation Accumulated on Closing Date Loss - ------------------------------------------------------------------------------------------- Safeco Large-Cap Growth Fund $697,836 $(610,297) - -------------------------------------------------------------------------------- 39 Pioneer Growth Shares - -------------------------------------------------------------------------------- FACTORS CONSIDERED BY THE INDEPENDENT TRUSTEES IN APPROVING THE MANAGEMENT CONTRACT - -------------------------------------------------------------------------------- The Investment Company Act of 1940 requires that both the Board of Trustees and a majority of the Independent Trustees (collectively "the Trustees") vote separately annually to approve the Fund's management contract (the "Management Contract"). The Trustees have determined that the terms of the Management Contract are fair and reasonable and that renewal of the contract will enable the Fund to receive quality investment advisory services at a cost deemed reasonable and in the best interests of the Fund and its shareholders. In making such determinations, the Independent Trustees relied upon the assistance of counsel to the Independent Trustees and counsel to the Fund. Throughout the year, the Independent Trustees regularly met in executive session separately from the Interested Trustees of the Fund and any officer of Pioneer Investment Management, Inc., the Fund's adviser (the "Investment Adviser"), or its affiliates. While the Trustees, including the Independent Trustees, act on all major matters relating to the Fund, a significant portion of the activities of the Board of Trustees (including certain of those described herein) is conducted through committees, the members of which are comprised exclusively of Independent Trustees. Such committee meetings are attended by officers of the Fund or the Investment Adviser to the extent requested by the members of the committee. In evaluating the Management Contract, the Trustees conducted a review that was specifically focused upon the renewal of the Management Contract, and relied upon their knowledge, resulting from their meetings throughout the year, of the Investment Adviser, its services and the Fund. Both in meetings specifically dedicated to renewal of the Management Contract and at other meetings during the course of the year, the Trustees, including the Independent Trustees, received materials relating to the Investment Adviser's investment and management services under the Management Contract. These materials included (i) information on the investment performance of the Fund, a peer group of funds and an index, in each case selected by the Independent Trustees for this purpose, (ii) sales and redemption data in respect to the Fund, (iii) the general investment outlook in the markets in which the Fund invests, (iv) arrangements in respect of the distribution of the Fund's shares, (v) the procedures employed to determine the value of each of the Fund's assets, (vi) the Investment Adviser's management of the relationships with the Fund's unaffiliated service providers, (vii) the record of compliance with the 40 Pioneer Growth Shares - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- Fund's investment policies and restrictions and with the Fund's Code of Ethics and the structure and responsibilities of the Investment Adviser's compliance department, (viii) the nature, cost and character of non-investment management services provided by the Investment Adviser and its affiliates and (ix) the disclosures included in the Fund's prospectuses and reports to shareholders. Specifically in connection with the Independent Trustees' review of the Management Contract, the Independent Trustees requested and the Investment Adviser provided additional information in order to evaluate the quality of the Investment Adviser's services and the reasonableness of the fee under the Management Contract. Among other items, this information included data or analyses of (1) investment performance for one and three years and life of the Fund periods for the Fund and a peer group selected by the Independent Trustees for this purpose, (2) management fees incurred by a peer group of funds selected by the Independent Trustees for this purpose, (3) the advisory fees of comparable portfolios of other clients of the Investment Adviser, (4) expense ratios for the Fund and a peer group of funds selected by the Independent Trustees for this purpose, (5) the overall organization of the Investment Adviser, (6) the Investment Adviser's financial results and condition, including its and certain of its affiliates profitability from services performed for the Fund, (7) transfer agency fees and administrative reimbursements paid to the Investment Adviser or affiliates, (8) investment management staffing, and (9) operating expenses paid to third parties. The Trustees also reviewed information regarding the potential for the Fund and the Investment Adviser to benefit from further economies of scale in the management of the Fund in light of breakpoints in the Fund's management fee, reasonable growth expectations for the Fund and certain of the Fund's expenses that are not incurred as fees based on a percentage of net assets. The following summarizes matters considered by the Trustees in connection with their renewal of the Fund's Management Contract. The Trustees did not identify any single factor as all-important or controlling, and the summary does not detail all the matters that were considered. A. Ancillary Benefits to Shareholders. The Trustees considered the benefits to shareholders of investing in a Fund that is part of a large number of investment companies offering a variety of 41 Pioneer Growth Shares - -------------------------------------------------------------------------------- FACTORS CONSIDERED BY THE INDEPENDENT TRUSTEES IN APPROVING THE MANAGEMENT CONTRACT (continued) - -------------------------------------------------------------------------------- investment disciplines and providing for a large variety of Fund and shareholder services. B. Compliance and Investment Performance. The Trustees determined that the Investment Adviser had policies and systems reasonably designed to achieve compliance with the Fund's investment objectives and regulatory requirements. The Trustees also reviewed the Fund's investment performance based upon total return, as well as the Fund's performance compared to both the performance of a peer group and an index, in each case selected by the Independent Trustees for this purpose. The Fund's performance based upon total return was in the fifth quintile of the peer group for the 12 months ended June 30, 2004, the fifth quintile of the peer group for the three years ended June 30, 2004, and the fifth quintile for the five years ended June 30, 2004. (In all quintile rankings referred to throughout this discussion first quintile is most favorable to the Fund's shareholders. Thus, highest relative performance would be first quintile and lowest relative expenses also would be first quintile.) The Trustees noted that recently the Investment Adviser had changed the portfolio manager for the Fund. The Trustees concluded that the actions of the Investment Adviser in appointing a new portfolio manager with the objective of enhancing performance supported the continuation of the Management Contract. C. The Investment Adviser's Personnel and Methods. The Trustees reviewed the background of members of the team responsible for the daily management of the Fund and the Fund's investment objective and discipline. The Independent Trustees also have had discussions with senior management of the Investment Adviser responsible for investment operations and the senior management of the Investment Adviser's equities group. Among other things, the Trustees considered the number, education and experience of the Investment Adviser's investment staff and their use of technology and emphasis on analytics in view of the risk profile of securities in which the Fund invests. The Trustees concluded that the Investment Adviser had the quality and depth of personnel and the well-developed methods essential to performing its duties under the Management Contract. D. Nature and Quality of Other Services. The Trustees considered the nature, quality, cost and extent of other services provided to 42 Pioneer Growth Shares - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- shareholders of the Fund, including administrative and shareholder services performed by the Investment Adviser under the Management Contract. The Trustees also considered the reasonableness of the arrangements for reimbursement of the Investment Adviser's out-of-pocket costs and expenses, including overhead, for certain administrative services that the Investment Adviser is not required to provide under the Management Contract. The Trustees also considered the nature and extent of the other services provided by the Investment Adviser's affiliates under other contracts and its supervision of third party service providers. Based on these considerations, the Trustees concluded that the nature, quality, cost and extent of such services are satisfactory and reliable and serve the shareholders of the Fund well. E. Management Fee and Expenses. The Trustees considered the Investment Adviser's fee under the Management Contract relative to the management fees charged by a peer group of funds selected by the Independent Trustees for this purpose using data provided by an independent third party. The Fund's management fee for the 12 months ended June 30, 2004 was in the second quintile relative to the management fees paid by the other funds in that peer group for the comparable period. The Trustees also considered that the Fund's performance fee structure aligns the interests of shareholders and the Investment Adviser. The Trustees noted that the Investment Adviser was waiving the floor on the management fee but did not take that into consideration in evaluating the contract. The Trustees determined that the fee under the Management Contract was reasonable and fair in light of both the overall nature and quality of services provided by the Investment Adviser and the fees charged by the funds in the peer group. The Trustees also considered the Fund's expense ratio and expense ratios of a peer group of funds selected by the Independent Trustees for this purpose. The Fund's expense ratio for the 12 months ended June 30, 2004 was in the third quintile of the applicable peer group for the most recent fiscal year of the peer group for the comparable period. The Trustees concluded that the Fund's overall expense ratio was reasonable compared to that of comparable funds. F. Profitability. The Trustees considered the level of the Investment Adviser's profits with respect to the management of the Pioneer Funds, including details with respect to the Fund. This consideration included a review of the Investment Adviser's methodology 43 Pioneer Growth Shares - -------------------------------------------------------------------------------- FACTORS CONSIDERED BY THE INDEPENDENT TRUSTEES IN APPROVING THE MANAGEMENT CONTRACT (continued) - -------------------------------------------------------------------------------- in allocating certain of its costs to the management of each Fund. The Trustees also considered the financial results realized by the Investment Adviser in connection with the operation of the Fund. They further considered the profits realized by the Investment Adviser and its affiliates from non-fund businesses that may benefit from or be related to the Fund's business. The Trustees considered the Investment Adviser's profit margins in comparison with the limited available industry data. The Trustees concluded that the Investment Adviser's profits from management of the Pioneer Funds, including the financial results derived from the Fund, bear a reasonable relationship to the services rendered and are fair for the management of the Fund. G. Economies of Scale. The Trustees considered the economies of scale with respect to the management of the Fund, whether the Fund had appropriately benefited from any economies of scale, and whether there was potential for realization of any further economies of scale. Because of break points in the management fees, the Trustees concluded that any perceived or potential economies of scale would be shared in a reasonable manner as the Fund grows in size between Fund's shareholders and the Investment Adviser. H. Other Benefits to the Investment Adviser. The Trustees also considered the character and amount of fees paid by the Fund, other than under the Management Contract, for services provided by the Investment Adviser and affiliates, including fees for services such as shareholder services. The Trustees also considered the receipt of sales loads and payments under Rule 12b-1 plans in respect to the Pioneer Funds (including the Fund), and benefits to the Investment Adviser from the use of "soft" commission dollars to pay for research and brokerage services. The Trustees further considered the revenues and profitability of the Investment Adviser's businesses other than the fund business, including the Investment Adviser's institutional investment advisory business. The Trustees considered the intangible benefits that accrue to the Investment Adviser and its affiliates by virtue of its relationship with the Fund and the Pioneer Funds as a group. The Trustees concluded that all these types of benefits accruing to the Investment Adviser were reasonable in the context of the overall relationship between the Investment Adviser and the Fund. 44 Pioneer Growth Shares - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- Conclusion. The Trustees, in light of the Investment Adviser's overall performance, considered it appropriate to continue to retain the management services of the Investment Adviser. Based on their evaluation of all material factors deemed relevant and the advice of independent counsel, the Trustees concluded that the Management Contract with the Fund is fair and reasonable and voted to approve the continuation of the Management Contract for another year. 45 Pioneer Growth Shares - -------------------------------------------------------------------------------- TRUSTEES, OFFICERS AND SERVICE PROVIDERS - -------------------------------------------------------------------------------- Trustees Officers John F.

PIONEER FUNDS APPROVAL OF AUDIT, AUDIT-RELATED, TAX AND OTHER SERVICES PROVIDED BY THE INDEPENDENT AUDITOR SECTION I - POLICY PURPOSE AND APPLICABILITY The Pioneer Funds recognize the importance of maintaining the independence of their outside auditors. Maintaining independence is a shared responsibility involving Pioneer Investment Management, Inc ("PIM"), the audit committee and the independent auditors. The Funds recognize that a Fund's independent auditors: 1) possess knowledge of the Funds, 2) are able to incorporate certain services into the scope of the audit, thereby avoiding redundant work, cost and disruption of Fund personnel and processes, and 3) have expertise that has value to the Funds. As a result, there are situations where it is desirable to use the Fund's independent auditors for services in addition to the annual audit and where the potential for conflicts of interests are minimal. Consequently, this policy, which is intended to comply with Rule 210.2-01(C)(7), sets forth guidelines and procedures to be followed by the Funds when retaining the independent audit firm to perform audit, audit-related tax and other services under those circumstances, while also maintaining independence. Approval of a service in accordance with this policy for a Fund shall also constitute approval for any other Fund whose pre-approval is required pursuant to Rule 210.2-01(c)(7)(ii). In addition to the procedures set forth in this policy, any non-audit services that may be provided consistently with Rule 210.2-01 may be approved by the Audit Committee itself and any pre-approval that may be waived in accordance with Rule 210.2-01(c)(7)(i)(C) is hereby waived. Selection of a Fund's independent auditors and their compensation shall be determined by the Audit Committee and shall not be subject to this policy.

Any services outside the specific pre-approved service subcategories set forth above must be specifically approved by the Audit Committee. o At least quarterly, the Audit Committee shall review a report summarizing the services by service category, including fees, provided by the Audit firm as set forth in the above policy. - -------------------------------------------------------------------------------- (2) Disclose the percentage of services described in each of paragraphs (b) through (d) of this Item that were approved by the audit committee pursuant to paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X. N/A (f) If greater than 50 percent, disclose the percentage of hours expended on the principal accountant's engagement to audit the registrant's financial statements for the most recent fiscal year that were attributed to work performed by persons other than the principal accountant's full-time, permanent employees. N/A (g) Disclose the aggregate non-audit fees billed by the registrant's accountant for services rendered to the registrant, and rendered to the registrant's investment adviser (not including any sub-adviser whose role is primarily portfolio management and is subcontracted with or overseen by another investment adviser), and any entity controlling, controlled by, or under common control with the adviser that provides ongoing services to the registrant for each of the last two fiscal years of the registrant. The Fund's independent auditor, Ernst & Young LLP ("E&Y"), has advised the Securities and Exchange Commission, the Public Company Accounting Oversight Board, and the Audit Committee of the Fund's Board of Trustees that certain non-audit work performed by E&Y's China affiliate raised questions regarding E&Y's independence with respect to its performance of audit services for the Fund. In July 2004, E&Y became aware that member firms in China ("E&Y China") provided certain tax services to offices of UniCredito Italiano, S.p.A. ("UCI"), a member of the Fund's Investment Company Complex. The services included receipt and disbursement of monies transferred to E&Y China by UCI in payment of individual expatriate income taxes due on returns prepared by E&Y China for certain UCI employees located in China from October 1998 to May 2003. E&Y became auditors of the Fund in May 2002. These expatriate tax services were discontinued in May 2003. The fees received by E&Y China for all such services totaled $3,685. The Fund's Audit Committee and E&Y have discussed the matter, including the nature of the services provided, the personnel involved in providing the services and the fees received by E&Y for performing the services. E&Y has informed the Audit Committee that based on its internal reviews and the de minimis nature of the services provided and fees received, it does not believe its independence with respect to the Fund has been impaired. N/A (h) Disclose whether the registrant's audit committee of the board of trustees has considered whether the provision of non-audit services that were rendered to the registrant's investment adviser (not including any subadviser whose role is primarily portfolio management and is subcontracted with or overseen by another investment adviser), and any entity controlling, controlled by, or under common control with the investment adviser that provides ongoing services to the registrant that were not pre-approved pursuant to paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X is compatible with maintaining the principal accountant's independence.
