Dear Shareowner,
- --------------------------------------------------------------------------------
Staying diversified and keeping your portfolio invested in the markets are two
general investment principles that have served investors well over time. They
were particularly useful guides during the past year, when an otherwise healthy
long-term bull market was buffeted by problems in the mortgage and banking
industries.

Since mid-year, issues tied to poor underwriting practices in the subprime
sector of the mortgage industry and to problems with risk management by banks
and hedge funds have resulted in increased market volatility and rising concern
about risks to U.S. economic growth.

Even against this backdrop, the long-term performance of major asset classes
remained positive. In the 12 months ending September 30, 2007, equity investors
were generally rewarded as, despite several interim corrections, the Standard &
Poor's 500 Index returned 16%, the Dow Jones Industrial Average returned 22%,
and the NASDAQ Composite Index returned 20%. International developed and
emerging markets equities performed even better, reflecting both a weakening
dollar (which boosts returns for U.S. dollar-based investors) and strong local
currency returns, with the MSCI EAFE Developed Market Index returning 25% and
the MSCI Emerging Markets Index returning 59% over the same 12-month period. The
U.S. bond market, as measured by the Lehman Aggregate Bond Index, returned 5% in
the 12 months ending September 30, 2007. The U.S. high-yield bond market, as
measured by the Merrill Lynch High Yield Bond Master II Index, returned 8% for
the same period, reflecting its higher coupon yield.

U.S. economic growth has slowed in the past year, but this was due as much to
the natural maturation of the cyclical expansion, as U.S. factories approached
full utilization and the labor market approached full employment, as it was to
rising commodity prices or short-term interest rates. This slowdown was,
therefore, not entirely unwelcome, as it reduced the threat of higher inflation.
More recently, however, there has been increasing concern that falling home
prices, and/or disruptions in financial markets pose a larger threat to
continuing economic growth. A weaker U.S. dollar has put upward pressure on some
prices, but it has also benefited exporters and companies competing in the
global marketplace.

Although U.S. economic growth has slowed, growth in the rest of the world
remains relatively strong. In Europe, robust GDP growth driven by a positive
operating environment for European companies, especially exporters, has driven
unemployment lower and supported growing consumption, although concerns about
the impact of the strong Euro are a persistent source of worry. Japanese
economic growth continues, albeit at a muted rate, and the country's
deflationary problems are gradually receding. Economic growth in

2


Letter

emerging market countries remains faster than in the developed world as they
persist in "catching up," led by China, which continues its rise as a world
economic power.

The U.S. Federal Reserve and the world's other central banks have pursued
policies aimed at producing low and stable inflation, believed to be the best
backdrop for steady economic growth and low average unemployment over the long
term. Keeping inflation low is also an important support for stock and bond
valuations, and so central bank policies have also been "investor friendly."

Looking forward, the economic outlook appears generally positive, although real
estate prices, subprime mortgage defaults, and the possibility of a systemic
liquidity/credit crunch all represent sources of risk. Central banks responded
to this summer's liquidity squeeze in the inter-bank and commercial paper
markets by acting as "lenders of last resort" and, in September 2007, the Fed
cut rates to limit the risk of credit market problems spreading to the broader
economy. While falling risk tolerances and reducing leverage may depress asset
prices in the short term, valuations look reasonable if "Wall Street" problems
do not spread to the broader "Main Street" economy.

Sudden swings in the markets are always to be expected. Just as staying
diversified and invested are important investment principles, it is also
important to pay attention to asset allocation. As always, we encourage you to
work closely with your financial advisor to find the mix of stocks, bonds and
money market assets that is aligned to your particular risk tolerance and
investment objective.

Respectfully,

/s/ Daniel K. Kingsbury

PORTFOLIO MANAGEMENT DISCUSSION 9/30/07
- --------------------------------------------------------------------------------

Equities turned in generally solid performance during the six months ended
September 30, 2007, despite severe market volatility in July and early August
brought on by concerns about the sub-prime mortgage and structured finance
markets. Healthy profits and strong balance sheets encouraged investor
confidence in stocks, especially large-cap growth stocks. In the following
interview, Andrew Acheson and Timothy Mulrenan discuss the factors that affected
the performance of Pioneer Fundamental Growth Fund during the six months. Mr.
Acheson and Mr. Mulrenan are co-managers of the Fund.

Q:   How did the Fund perform during the six months ended September 30, 2007?

A:   The Fund produced a healthy return despite trailing its benchmark and
     Lipper peer group average. Pioneer Fundamental Growth Fund Class A shares
     generated a total return of 10.57% at net asset value over the six months.
     During the same period, the benchmark Russell 1000 Growth Index rose
     11.35%, while the average return of the 755 funds in Lipper's Large Cap
     Growth category was 13.14%.

     Call 1-800-225-6292 or visit www.pioneerinvestments.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 was the investment environment like during the six months?

A:   We had a favorable backdrop for investing in large-cap growth companies for
     most of the period. Company profits continued to grow, although at a
     decelerating rate, corporate balance sheets remained solid, equity
     valuations were reasonable, and long-term interest rates stayed low by
     historical standards. The weakening of the U.S. dollar tended to help the
     earnings of those large companies with exposure to foreign economies, most
     of which were growing faster than the U.S. economy. The environment was
     particularly supportive for large-cap growth stocks, which we emphasize.
     After having been outperformed by value stocks for several years, growth
     stocks entered the period undervalued relative to value

Pioneer Fundamental Growth Fund
- --------------------------------------------------------------------------------

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

     stocks, despite having higher growth rates, higher returns on equity and
     healthy balance sheets. Moreover, growth stocks have shown an historical
     tendency to outperform when economic growth has decelerated. Large-cap
     growth stocks, in particular, had the advantage of geographic diversity,
     with exposure to opportunities in foreign markets. While large-cap growth
     stocks were affected by the market sell-off in mid-summer that was
     precipitated by the aforementioned problems in the subprime mortgage and
     structured finance industries, they retained their existing advantages as
     the market stabilized and began to recover following intervention by the
     U.S. Federal Reserve Board (the Fed). To inject new liquidity into the
     financial markets, the Fed lowered key short-term interest rates - first
     the discount rate in August, and then both the fed funds rate and the
     discount rate in September. The moves encouraged investor confidence that
     the nation's central bank was prepared to act in the face of a
     deteriorating situation.

Q:   What changes did you make in the Fund's portfolio over the six months?

A:   We made some changes in the Fund's positioning during the period. We
     sharpened our focus on large-cap growth companies with firm business
     fundamentals and earnings that we believed could be sustained, even as the
     business cycle entered a decelerating period. We emphasized companies that
     we believed had strong management teams capable of executing their business
     plans. We increased our investments in the Consumer Staples and Health Care
     sectors, where we found companies with stronger balance sheets and more
     stable growth prospects. At the same time, we shifted focus away from
     financials stocks, where we had concerns about some parts of the credit
     markets. We also de-emphasized investments in retailing stocks because of
     uncertainty about prospects for consumer spending growth.

     In the Consumer Staples sector, one of our notable additions was Coca-Cola.
     The company has been diversifying away from its heavy emphasis on
     carbonated soft drinks by introducing new products that have greater appeal
     in the global distribution network it has built. In the Health Care sector,
     a major new investment was Thermo Fisher Scientific, which after a
     corporate merger has emerged as the premier franchise among producers of
     scientific equipment and instruments for the life sciences industries.

                                                                               5

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

     Among the holdings we liquidated were home improvement retailers Home Depot
     and Lowe's, as we saw continued weakness in the residential construction
     industry. We also eliminated a few Information Technology stocks because of
     deterioration in their prospects. These included: Macrovision, a developer
     of copyright software protection for the entertainment industry; Motorola,
     the well-known telecommunications equipment company; and Palm, a producer
     of hand-held wireless communications devices. We also sold our investment
     in TXU, the Texas-based utility, as a group of private investors announced
     plans to acquire the company in a leveraged transaction.

Q:   What types of investments most influenced the Fund's results during the
     period?

A:   Cisco Systems and Juniper Networks, two information network equipment
     companies, both made large gains during the six months. These two Fund
     holdings benefited from increasing investments in network infrastructure to
     help facilitate rapidly increasing traffic over the Internet and corporate
     networks. In particular, the transmission of more video content over
     networks increased the demand for sophisticated infrastructure. Moreover,
     Cisco also gained from heavy investment in networking infrastructure in
     emerging markets, including in the Middle East.

     Among our Energy holdings, National Oil Well Varco was a standout. Its
     technology leadership in drilling equipment proved to be a profitable
     advantage as energy companies made heavy investments in new drilling
     equipment to meet growing demand for oil and gas.

     Investments that detracted from results included retailer Ross Stores and
     technology corporations Palm and Macrovision. Ross Stores, a major
     off-price retailer, was hurt by slowing sales trends in California, a state
     where the company has a major presence and where the slumping real estate
     market has affected consumer spending. However, we have maintained our
     position because we think the company has a strong franchise and good
     potential to expand its store base, and is in a position to benefit from
     its investments in productivity-enhancing technology. Palm saw its market
     share in hand-held, wireless communications devices shrink in the face of
     intense competition from the Blackberry products of Research In Motion and
     the new iPhone products of Apple.

     Macrovision suffered major setbacks in its effort to develop profitable
     agreements with major entertainment studios for its software product
     designed to protect against unauthorized use of copyright-protected
     programming.

Q:   What is your investment outlook?

A:   We are moderately optimistic about opportunities in the equity market,
     although we do see some reasons for caution. Our outlook is tempered by
     concerns about problems in the housing industry and the potential spillover
     effects on employment, personal income and consumption. At the same time,
     the persistent weakness of the U.S. dollar could increase inflationary
     pressures. In addition, questions still remain as to the full extent of
     potential weakness in the credit markets due to concerns about sub-prime
     mortgages and structured finance.

     Despite those concerns, two major factors encourage a more optimistic view.
     First, the global economic expansion continues at a healthy pace, with
     major positive impacts in the U.S. Second, stock valuations remain
     reasonable, especially in view of the continuing profit growth and solid
     balance sheets of corporations.

     We intend to maintain our investment discipline within this context,
     emphasizing high-quality companies with growth platforms that may allow
     them to benefit from the global economy. However, we are likely to continue
     to de-emphasize industries and sectors that are highly dependent on
     domestic cyclical trends, choosing to focus instead on corporations that
     have the potential to sustain their earnings in the face of a deceleration
     in the domestic economy.

At times, the Fund's investments may represent industries or industry sectors
that are interrelated or have common risks, making it more susceptible to any
economic, political, or regulatory developments or other risks affecting those
industries and sectors.

Pioneer Fundamental Growth Fund

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.

     reflect the one-half year 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.

     the period ended March 2003, the gross expenses ratio to average net assets
     would have been 5.31%. As a result of the expenses limitation arrangement
     (see footnote 2), there would be no effect on the per share operating
     performance, total return and the net expenses and net investment loss
     ratios to average net assets.

1.   Organization and Significant Accounting Policies

Pioneer Fundamental Growth Fund (the Fund), formerly Pioneer Large Cap Growth
Fund, is a Delaware statutory trust registered under the Investment Company Act
of 1940 as a diversified, open-end management investment company. The Fund was
organized on March 12, 2002, and commenced operations on August 22, 2002. Prior
to August 22, 2002, the Fund had no operations other than those relating to
organizational matters and the initial capitalization of the Fund by Pioneer
Funds Distributor, Inc. (PFD). The Fund's shares, including Class A shares, were
first publicly offered on December 15, 2005. Prior to December 15, 2005 all Fund
shares outstanding were owned by PFD. The Fund's investment objective is to seek
long-term capital growth.

The Fund offers three classes of shares - Class A, Class B and Class C shares.
Shares of Class A, Class B and Class C each represent an interest in the same
portfolio of investments of the Fund and have equal rights to voting,
redemptions, dividends and liquidation proceeds, except that each class of
shares can bear different transfer agent and distribution fees and have
exclusive voting rights with respect to the distribution plans that have been
adopted by Class A, Class B and Class C shareowners, respectively.

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.

At times, the Fund's investments may represent industries or industry sectors
that are interrelated or have common risks, making it more susceptible to any
economic, political, or regulatory developments or other risks affecting those
industries and sectors. Information regarding the Fund's principal risks is
contained in the Fund's prospectus(es). Please refer to those documents when
considering the Fund's investment risks.

The following is a summary of significant accounting policies followed by the
Fund in the preparation of its financial statements, which are

28


Pioneer Fundamental Growth Fund
- --------------------------------------------------------------------------------

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

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 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. As of September 30,
     2007, there were no securities fair valued. Temporary cash investments are
     valued at amortized cost which approximates market value.

     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
     date in exercise of reasonable diligence. Interest income, including
     interest on income bearing cash accounts, is recorded on the accrual basis.
     Dividends and interest 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.   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.

                                                                              29

NOTES TO FINANCIAL STATEMENTS 9/30/07 (unaudited)                  (continued)
- --------------------------------------------------------------------------------

     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 Fund has elected to defer $3,404 in capital losses recognized between
     November 1, 2006 and March 31, 2007 to its fiscal year ending March 31,
     2008.

     The tax character of current year distributions will be determined at the
     end of the fiscal year. The tax character of distributions paid during the
     year ended March 31, 2007 was as follows:

     The difference between book-basis and tax-basis unrealized appreciation is

C.   Fund Shares

     The Fund records sales and repurchases of its shares as of trade date. PFD,
     the principal underwriter for the Fund and a wholly owned indirect
     subsidiary of UniCredito Italiano S.p.A. (UniCredito

     Italiano), earned $277 in underwriting commissions on the sale of Class A
     shares during the six months ended September 30, 2007.

D.   Security 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 the account of the Fund. The loans are secured by
     collateral of at least 102%, at all times, of the fair value of the
     securities loaned. The fair value 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 sponsored by Brown Brothers
     Harriman & Co., the Fund's custodian.

E.   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.

F.   Class Allocations

     Distribution fees are calculated based on the average daily net asset value
     attributable to Class A, Class B and Class C shares of the Fund,
     respectively (see Note 4). 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

                                                                              31


Pioneer Fundamental Growth Fund
- --------------------------------------------------------------------------------
NOTES TO FINANCIAL STATEMENTS 9/30/07 (unaudited)                  (continued)
- --------------------------------------------------------------------------------

     each class and the ratable allocation of related out-of-pocket expense (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 the 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 and Class C shares can bear different transfer
     agent and distribution fees.

2.   Management Agreement

PIM, a wholly owned indirect subsidiary of UniCredito Italiano, manages the
Fund's portfolio. Management fees are calculated daily at the annual rate of
0.75% of the Fund's average daily net assets.

PIM has agreed not to impose its management fee and to assume other operating
expenses of the Fund to the extent necessary to limit expenses to 1.25%, 2.15%
and 2.15% of the average daily net assets attributable to Class A, Class B and
Class C shares, respectively. These expense limitations became effective
December 15, 2005 and are in effect through August 1, 2010 for Class A shares
and through August 1, 2008 for Class B and Class C shares. Prior to December 15,
2005, Pioneer had voluntarily agreed not to charge all or a portion of its
management fee and, if necessary, to limit other ordinary operating expenses to
the extent required to reduce Class A expenses to 1.30% of the Fund's average
daily net assets attributable to Class A shares.

In addition, under the management and administration agreements, certain other
services and costs, including accounting, regulatory reporting and insurance
premiums, are paid by the Fund. At September 30, 2007, $8 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 $8,997 in transfer agent fees
payable to PIMSS at September 30, 2007.

Pioneer Fundamental Growth Fund
- --------------------------------------------------------------------------------

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

4.   Distribution Plan

The Fund adopted a Plan of Distribution with respect to Class A, Class B and
Class C shares 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. Included in due to affiliates is $126 in distribution fees
payable to PFD at September 30, 2007.

In addition, redemptions of each class of shares may be subject to a contingent
deferred sales charge (CDSC). 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. 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. Redemptions of Class C shares
within one year of purchase are subject to a CDSC of 1.00%. Proceeds from the
CDSCs are paid to PFD. For the six months ended September 30, 2007, no CDSCs
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 September 30, 2007, the Fund's
expenses were reduced by $38 under such arrangements.

6.   New Pronouncements

In September 2006, Statement of Financial Accounting Standards No. 157, Fair
Value Measurements (SFAS 157), was issued and is effective for fiscal years
beginning after November 15, 2007. SFAS 157 defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair value
measurements. Management is currently evaluating the impact the adoption of SFAS
157 will have on the Fund's financial statement disclosures.

                                                                              33

 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.
