LETTER TO SHAREOWNERS 6/30/05
- --------------------------------------------------------------------------------

Dear Shareowner,
- --------------------------------------------------------------------------------
The U.S. economy has expanded at an annualized rate of at least three percent
for eight straight quarters, a feat it last achieved in the 1980s. 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.

Please consider a fund's investment objective, risks, charges and expenses
carefully before investing. The prospectus contains this and other information
about each fund and should be read carefully before you invest or send money.

performance data quoted.

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.

NAV results represent the percent change in net asset value per share. Returns
would have been lower had sales charges been reflected. POP returns reflect
deduction of maximum 5.75% sales charge. All results are historical and assume
the reinvestment of dividends and capital gains. Other share classes are
available for which performance and expenses will differ. Performance results
reflect any applicable expense waivers in effect during the periods shown.
Without such waivers Fund performance would be lower. Waivers may not be in
effect for all funds. Certain fee waivers are contractual through a specified
period. Otherwise, fee waivers can be rescinded at any time. See the prospectus
and financial statements for more information.

The performance table and graph do not reflect the deduction of fees and taxes
that a shareowner would pay on Fund distributions or the redemption of Fund
shares.

The Russell 1000 Growth Index measures the performance of large-cap U.S. growth
stocks. Companies in this index tend to exhibit higher price-to-book and
price-to-earnings ratios, lower dividend yields and higher forecasted growth
values than the value universe. Index returns assume reinvestment of dividends
and, unlike Fund returns, do not reflect any fees, expenses or sales charges.

The performance data quoted represents past performance, which is no guarantee

"If Held" results represent the percent change in net asset value per share.
Returns would have been lower had sales charges been reflected. "If redeemed"
returns reflect the deduction of applicable contingent deferred sales charge
(CDSC). Effective December 1, 2004, the period during which a CDSC is applied to
withdrawals was shortened to 5 years. The maximum CDSC for class B shares
continues to be 4%. For more complete information, please see the prospectus for
details. Note: Shares purchased prior to December 1, 2004 remain subject to the
CDSC in effect at the time you purchased those shares. For performance
information for shares purchased prior to December 1, 2004, please visit

Class C shares held for less than one year are also subject to a 1% contingent
deferred sales charge (CDSC). The performance of Class C shares does not reflect
the 1% front-end sales charge in effect prior to February 1, 2004. If you paid a
1% sales charge, your returns would be lower than those shown above. "If Held"

have been lower had sales charges been reflected. 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

Performance for periods prior to the inception of Class Y shares reflects the

COMPARING ONGOING FUND EXPENSES
- --------------------------------------------------------------------------------

As a shareowner in the Fund, you incur two types of costs:

(1) ongoing costs, including management fees, distribution and/or service
    (12b-1) fees, and other Fund expenses; and

(2) transaction costs, including sales charges (loads) on purchase payments.

This example is intended to help you understand your ongoing expenses (in
dollars) of investing in the Fund and to compare these costs with the ongoing
costs of investing in other mutual funds. The example is based on an investment
of $1,000 at the beginning of the Fund's latest six-month period and held
throughout the six months.


Using the Tables

Actual Expenses

The first table below provides information about actual account values and
actual expenses. You may use the information in this table, together with the
amount you invested, to estimate the expenses that you paid over the period as
follows:

1. Divide your account value by $1,000
   Example: an $8,600 account value [divided by] $1,000 = 8.6

2. Multiply the result in (1) above by the corresponding share class's number
   in the third row under the heading entitled "Expenses Paid During Period"
   to estimate the expenses you paid on your account during this period.

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.

PORTFOLIO MANAGEMENT DISCUSSION 6/30/05
- --------------------------------------------------------------------------------

Large company growth stocks slumped early in 2005 before staging a comeback in
May and June. 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%.

   Call 1-800-225-6292 or visit www.pioneerfunds.com for the most recent
   month-end performance results. Current performance may be lower or higher
   than the performance data quoted.

   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

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.

   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.

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.

- --------------------------------------------------------------------------------

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

- --------------------------------------------------------------------------------

   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:

   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.

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.

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"):

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

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

- --------------------------------------------------------------------------------

   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

- --------------------------------------------------------------------------------


- --------------------------------------------------------------------------------

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 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.

                                              restricted services.
- ------------------------------------------- ------------------------------

- --------------------------------------------------------------------------------
GENERAL AUDIT COMMITTEE APPROVAL POLICY:
o For all projects, the officers of the Funds and the Fund's auditors will each
  make an assessment to determine that any proposed projects will not impair
  independence.

o Potential services will be classified into the four non-restricted service
  categories and the "Approval of Audit, Audit-Related, Tax and Other
  Services" Policy above will be applied. 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.
