Dear Shareholders,

This is the first quarterly report by the new team of Vince Gallagher and Jim
Kloppenburg, who replaced Peter Trapp as joint portfolio managers for the
Needham Growth Fund ("NGF" or the "Fund") on April 22, 2003. Vince has been
running the Needham Small Cap Growth Fund since its inception on May 22, 2002
and Jim has been running the Needham Aggressive Growth Fund since its inception
on September 4, 2001. We plan to continue the Fund's successful "Growth at a
Reasonable Price" ("GARP") approach. We are pleased to report on page 2 our

June 30, 2003 ("6 months"), the year ended June 30, 2003 ("1 Year"), the
three-year period ended June 30, 2003 ("3 Years"), the five-year period ended
June 30, 2003 ("5 Years") and from January 1, 1996 to June 30, 2003 ("since

NGF seeks to create long-term, tax-efficient capital appreciation for its
investors. To this end, NGF targets companies with products or services that are
selling or marketing into high-growth markets. These companies normally have
earnings growth of at least 15-20%, product and market dominance, and the
ability to consolidate their market positions. They may also have a competitive
advantage by acquiring and retaining more customers or driving costs down and
profits up. NGF also looks for seasoned and motivated managements with records
of building shareholder value. Companies with these characteristics sometimes
find themselves in a temporary earnings downturn or shortfall or may be in a
product transition. This often causes aggressive growth or dynamic growth
investors to sell. At this point, NGF may deem the stock to be reasonably priced
and purchase it for long-term capital appreciation. Hence, the discipline called
"Growth At a Reasonable Price," or GARP.

                                                                               1

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

After April 22, we decided that the number of positions in the Fund had become
unmanageable and we embarked on a strategy to reduce the overall number of
holdings in the Fund from 155 to 125 at June 30. In addition, within the
holdings, we have reduced the concentration on energy/industrial/ metals names
from 30.5% in mid-April down to 14.8% at June 30 and may bring that lower to
create better diversification in the Fund. These actions were a continuation of
programs that had begun earlier in the year. Overall, at June 30, we had a
reasonable short position (13.03%), an attractive cash position (24.7%), and a
seasoned portfolio of long stock investments that performed very well during the
second quarter.

As shown below, we outperformed all four of the benchmark indices in the second
quarter of 2003, as technology and telecom led the market higher; we believe it
was more a bounce from severely depressed levels than strength in the economy or
a turn-up in business where there is still significant overcapacity, especially
in technology. As discussed above, we spent most of the second quarter trimming
back the number of holdings, taking some gains and losses in the process and
creating what we hope will be a better balanced portfolio going into the second
half of the year. We added one or two new names, and we hope to add more as the
year progresses. On the short side, we reduced many of our positions in late
April and early May, going from over 20% down to about 13.03%. This action
benefited the Fund substantially as the market continued the April rally into
May and then June.

The equity markets staged an impressive rally in the second quarter of 2003,
ending the quarter up 15.4% as measured by the S&P 500 Index and rising 23.9%
from the March 11 intraday low to the recent high on June 17. Investor sentiment
surveys have also shown a corresponding rise in investor optimism off the March
lows, as an increasing number of market participants believe the three-year bear
market to be over.

From the current list of top ten holdings, two are new and eight are repeat
performers. Exiting the list are two energy names: Halliburton Co. and
Patterson-UTI Energy. This was part of our strategy, touched on above. New to
the list are Computer Associates and Ceradyne, Inc. Computer Associates has long
been a name followed by the Fund; when the stock was beaten down in 2002, we
built up a meaningful position that has appreciated nicely during 2003. Ceradyne
is a new technology name and the only small cap name in our top ten holdings.
The company, based in Southern California, is a leader in sophisticated
ceramics.

Our primary focus remains in the technology space, a core competency at Needham
& Company, representing 46.1% of our long exposure and 40.01% of our net
exposure, down from our 48.15% net exposure at the end of 1Q03. Our net exposure
in energy/industrial/metals has decreased from 30.5% to 14.8%, as we moved to
reduce our exposure to the group. We increased our cash and fixed income
investments from 5.24% to 24.72%. We prefer to be less than fully invested in
this current market.

While this rally has certainly been impressive, it is not unique. In fact, there
have been seven double-digit rallies of the S&P 500 Index since the market
peaked in early 2000, with five of those (including the present rally) having
gains of greater than 20%. The first six of those rallies eventually failed. It
has yet to be seen whether the second quarter 2003 rally will prove to be the
start of a more sustainable market recovery or just another rally within a bear
market.

                                                                               3

There have been some key improvements that have warranted a more positive
revaluation in stocks: the quick end of the Hussein regime in Iraq, the progress
on the tax front and, perhaps most important, more accommodating financial
markets that are allowing the strengthening of corporate balance sheets. On the
other hand, the magnitude of the stock moves, particularly in the high-beta
names, has once again anticipated a big recovery in the economy that we have yet
to see materialize.

The Federal Reserve has been working overtime to pump liquidity into the system
and to keep deflation at bay, and there has been a big short squeeze. We think
that both influences are running out of steam and that the likelihood of a
pullback in stocks has increased, particularly in the high-octane sectors of the
market that have fueled this rally.

As noted above, most of our efforts in the second quarter were made to reduce
the number of holdings to a more manageable level; to reduce our inherited short
position of 20% down to a more reasonable 11-13% level; to raise cash throughout
this 2Q03 rally so that we exited the quarter with almost 25% cash in the Fund;
and to preserve our flexibility so that we can take advantage of any pullback in
this market. We accomplished all of the above during the quarter and are now
prepared to take advantage of whatever the market has to offer.

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

The Fund continues, for the patient investor, to outperform the long-term
comparable indices, thanks to our GARP discipline, our focus on small to mid-cap
companies, the special situation investments, and our ability to hedge,
including short sales. The Fund also continues to focus on preservation of
capital and long-term capital appreciation. While we have a superior investment
record of nearly seven years, we continue to advise shareholders and potential
investors not to be rattled by short-term disappointments and to temper their
expectations and focus on realistic investment goals and returns.

For those of you who have invested, whether recently or over the life of the
Fund, we thank you for your confidence and support. We try to earn that
confidence every quarter. We believe the patient three-to-five-year investor
will be better rewarded. The Fund continues to be rated five stars by
Morningstar(TM) for five years and overall.(1)

- -------------
(1) For each fund with at least a three-year history, Morningstar(TM) calculates
    a Morningstar(TM) Rating based on a Morningstar(TM) Risk-Adjusted Return
    measure that accounts for variation in a fund's monthly performance
    (including the effects of sales charges, loads, and redemption fees),
    placing more emphasis on downward variations and rewarding consistent
    performance. The top 10% of funds in each category receive 5 stars, the next
    22.5% receive 4 stars, the next 35% receive 3 stars, the next 22.5% receive
    2 stars and the bottom 10% receive 1 star. (Each share class is counted as a
    fraction of one fund within this scale and rated separately, which may cause
    slight variations in the distribution percentages.) The Overall
    Morningstar(TM) Rating for a fund is derived from a weighted-average of the
    performance figures associated with its three-, five- and ten-year (if
    applicable) Morningstar(TM) Rating metrics. The Needham Growth Fund was
    rated against the following numbers of U.S.-domiciled Small-Cap Growth funds
    over the following time periods: 457 funds in the last three years and 330
    funds in the last five years. With respect to these Small-Cap Growth funds,
    the Needham Growth Fund received a Morningstar(TM) Rating of 4-stars,
    5-stars and 5-stars for the three-year period, five-year period and overall,
    respectively. Past performance is no guarantee of future results.

Needham Aggressive Growth Fund                            SEMIANNUAL REPORT 2003
- --------------------------------------------------------------------------------

Dear Shareholders,

We are pleased to report below the performance results for the Needham
Aggressive Growth Fund ("NAGF" or the "Fund"), NASDAQ symbol NEAGX, for the six
months ended June 30, 2003 ("6 months"), for the year ended June 30, 2003 ("1
Year") and from September 4, 2001 to June 30, 2003 ("since inception"). The Fund
was up 14.69% for the quarter ended June 30, 2003, is up 3.58% for the trailing
12 months and is up 2.12% since inception compounded annually.

NAGF seeks to create long-term, tax-efficient capital appreciation for its
investors. To this end, NAGF targets the equities of companies with strong,
above-average prospective growth rates. The Fund invests, in general, in markets
and industries with strong growth rates, focusing on the market leaders in these
areas. These market leaders, especially as they break away from their
competitors, tend to garner a disproportionate share of the positive financial
returns. Also important is the long-term sustainability of the companies'
leadership positions. Thus, the Fund looks for companies with strong management
teams, superior balance sheets, above-average margins that can generate excess
cash, and strong R&D and brand spending in industries with high barriers to
entry.

The equity markets staged an impressive rally in the second quarter of 2003,
ending the quarter up 15.4% as measured by the S&P 500 Index and rising 23.9%
from the March 11 intraday low to the recent high on June 17. Investor sentiment
surveys have also shown a corresponding rise in investor optimism off the March
lows, as an increasing number of market participants believe the three-year bear
market to be over.

The highest beta stocks have been the biggest beneficiaries of this equity
updraft, with the beaten-down technology sector leading the way. This has had a
favorable impact on NAGF, as the electronic food chain remains the sector of
greatest exposure to the Fund at 28.2% net exposure as of June 30, 2003, though
our significant investments in less economically sensitive sectors such as
healthcare and business services has moderated those benefits to some extent
during the quarter. The rally has been particularly favorable for smaller cap
names, as evidenced by the NASDAQ Composite handily outperforming both the DJIA
and the S&P 500 indices in the quarter. The recent market run has clearly been
all beta, all the time.

Heavily shorted names were also among the best performers in the quarter and
contributed to the Fund's underperformance relative to the NASDAQ during the
second quarter. Fortunately, our short

exposure was only 4.4% of total investments upon entering the quarter, so the
negative drag was not significant. We highlighted in our last letter the buildup
in indiscriminate shorting that we were observing, and the resulting short
squeeze was an important contributor to the market's ascent in the second
quarter and a key reason why we had reduced the Fund's short exposure to a low
level. At current prices, we are finding better risk/rewards on the short side
and have begun to increase our shorts. That said, some of the thinner trading
names are still hard to borrow. They are overextended as stocks in our opinion,
but we are having trouble taking advantage of that opportunity.

One of our active strategies over the past six months has been to reduce the
number of core names in the portfolio. NAGF's top ten holdings now represent
32.6% of total investments as of June 30, up from 27.6% at the end of March. We
used the strong equity tape to eliminate a number of smaller positions and
redeployed those proceeds into some of the Fund's core holdings, thus increasing
our average exposure per holding. We think the market's significant volatility
is enabling us to enhance the Fund's long-term value. We have used the dips to
add to positions that we believe hold excellent long-term appreciation
potential, franchises that should thrive in multiple economic environments.

Our largest position at present is Seagate Technology, the worldwide leader in
hard disk drives, a market segment we have had extensive experience with
throughout Needham's history. We were able to take a large position when the
company returned to the public markets in December 2002 after a leveraged
buyout. Although the stock initially went through a post-IPO swoon, having come
public in a pessimistic technology tape and not being well understood, the stock
has since traded strongly, as the company has consistently delivered healthy
upside to earnings. Even at the current prices, the stock trades at a discount
to other dominant technology companies. For example, Seagate trades at only
one-third the price to sales ratio of EMC, even though they both serve the same
enterprise storage market. In fact, we would make the case that Seagate's
opportunities are ultimately larger, as the company is just now entering the
notebook market, which is the fastest-growing component of the PC marketplace,
and as hard disk drives penetrate deeper into the consumer electronics space in
key applications such as personal video recorders. In a business requiring both
scale and technology prowess, we think only Hitachi Data Systems has the
potential to stay competitive with Seagate over time.

While this rally has certainly been impressive, it is not unique. In fact, there
have been seven double-

digit rallies of the S&P 500 Index since the market peaked in early 2000, with
five of those (including the present rally) with gains of greater than 20%. The
first six of those rallies eventually failed. It has yet to be seen whether the
second quarter 2003 rally will prove to be the start of a more sustainable
market recovery or just another bear market head fake.

Our position is that it has been a little bit of both. There have been some key
improvements that have warranted a more positive revaluation in stocks: the
quick end of the Hussein regime in Iraq, the progress on the tax front and,
perhaps most important, more accommodating financial markets that are allowing
the strengthening of corporate balance sheets. On the other hand, the magnitude
of the stock moves, particularly in the high-beta names, has once again
anticipated a big recovery in the economy that we have yet to see materialize.
We think it is unlikely that growth will return fast enough to support the
current valuations and that many stocks have moved too far too fast.

The Federal Reserve has been working overtime to pump liquidity into the system
and to keep deflation at bay. We believe this has been a big factor in the
equity market's quick ascent, as has been the big short squeeze we noted above.
We think that both influences are running out of steam and that the likelihood
of a pullback in stocks has increased, particularly in the high-octane sectors
of the market that have fueled this rally.

Although we have consistently put cash to work over the past nine months, we
still have a healthy cash position at about 22% of total investments. This
should provide the Fund some protection if stocks retrace a portion of their
recent gains and keep us in a position to add to key holdings on a market
pullback. Given our growth -- albeit slow growth -- outlook, it wouldn't
surprise us to see both our long and short positions increase over the balance
of the year at the expense of the cash.

Needham Small Cap Growth Fund                             SEMIANNUAL REPORT 2003
- --------------------------------------------------------------------------------

Dear Shareholders,

We are pleased to report below the performance results for the Needham Small Cap
Growth Fund ("NSCGF" or the "Fund"), NASDAQ symbol NESGX, for the six months
ended June 30, 2003 ("6 months"), for the year ended June 30, 2003 ("1 Year")
and from May 22, 2002 to June 30, 2003 ("since inception"). The Fund was up
34.72% for the quarter, is up 40.24% for the year and up 26.75% compounded
annually since its inception on May 22, 2002.

The Fund seeks long-term, tax-efficient capital appreciation by investing
primarily in equity securities of smaller growth companies which the Fund
believes are trading at a discount to their underlying value yet have the
potential for superior long-term growth. Under normal conditions, the Fund
invests at least 80% of its total assets in equity securities of domestic
issuers that have market capitalizations of $2 billion or less and that are
listed on a nationally recognized securities exchange or traded on the Nasdaq
system. Central to the Fund's investment strategy is a sound valuation
discipline that seeks to acquire growth companies at reasonable prices. The Fund
seeks tax efficiency by holding securities for a period of 12 months or more to
obtain long-term capital gain treatment and by offsetting capital gains on the
sale of securities with capital losses.

We are very pleased with the Fund's performance in the second quarter. We took
advantage of the updraft to reduce the number of positions in the Fund down to
44 longs and 8 shorts. We also managed to diversify the holdings. We reduced our
exposure in technology and telecommunications from 60.8% at March 31 to 37.4% at
June 30. We plan to keep technology at about that level. We increased our
healthcare-related holdings from 8.73% to 16.09%. We would like to get that
sector closer to 20% over the coming months. We also dramatically increased our
cash position from 6.27% at the end of March to 23.43% at June 30.

All this happened while growing the Fund's NAV 34.72% in the quarter. We would
be very pleased if we could duplicate that performance going forward and that is
our goal. Markets have been and will continue to be volatile. We cannot control
the markets. What we can control is our efforts to uncover outstanding companies
to add to the portfolio. We plan to add such companies at reasonable prices and
then let them compound over the next three-to-five years for the benefit of our
investors.

This market has had a substantial move in the second quarter, and the question
is not "are the technology stocks ahead of themselves" because

assuredly they are. The real question is: "Given that fact, will the market take
them back down in the third or fourth quarter, similar to July and then October
2002?" My gut feeling is that we could see a 5-10% correction at any time, but I
do not see a wholesale sell-off. There simply are not enough attractive
alternatives out there. The bond market is at its lowest yields in over 40
years; real estate has done well but that market is somewhat frothy, and money
market funds . . . enough said. There are not many great alternatives out there,
and cash continues to flow into the markets looking for an acceptable return.
Given all of the above, we believe that this market could go sideways or even up
over the next six months.

Nonetheless, we do not predict markets and since we recognize the price
appreciation that has gone on in the second quarter, we will hedge our bets and
become more market neutral going forward. Part of this strategy started in June
when we increased our cash position from 6% to 23%. We have also started to add
to our short positions to protect the portfolio in the event of a sell-off. As
such, our gains may be tempered on the upside but our downside should also be
moderated.
Again, we want to extend a very appreciative thank you to our investors for
showing confidence in a new fund in a second challenging year. We will be
working hard to reward your confidence during the rest of 2003 and beyond by
seeking out attractive long-term growth companies that we can purchase at
reasonable prices. We are pleased to note that in early July net assets exceeded
$7.0 million and the Fund continues to grow. We also wanted to respond to a
number of our contemporaries who are moving their portfolios more toward fixed
income and tax-exempt bonds and are somewhat reluctant to invest in "small
caps." We are always pleased to set up accounts for children and grandchildren
under a Uniform Gift for Minors Account ("UGMA"), or their IRAs, if they have
one. We believe that "small caps" will be an attractive sector of the market,
particularly over the long haul.

             For the six months ended June 30, 2003, these are the holdings that
             made the largest dollar difference in the portfolio. While some
             minor holdings experienced greater percentage changes in price, the
             change in their dollar value did not on an individual basis, have a
             meaningful effect on the Fund's net assets. Past performance of
             these holdings is historical and does not guarantee future results.

Notes to Financial Statements (Unaudited)

1. ORGANIZATION

Needham Growth Fund ("NGF"), Needham Aggressive Growth Fund ("NAGF"), and
Needham Small Cap Growth Fund ("NSCGF") or ("the Portfolios"), are portfolios of
The Needham Funds, Inc. (the "Fund"), which is registered under the Investment
Company Act of 1940 as a non-diversified, open-end management investment
company. The Needham Funds, Inc. was organized as a Maryland corporation on
October 12, 1995.

2. SIGNIFICANT ACCOUNTING POLICIES

Security Valuation: Investments in securities (including options) listed or
traded on a nationally recognized securities exchange are valued at the last
quoted sales price on the date the valuations are made. Effective May 5, 2003,
securities regularly traded in the over-the-counter market are valued at the
NASDAQ Official Closing Price ("NOCP"). If no sales price or NOCP is available
for a listed or NASDAQ security, or if the security is not listed on NASDAQ,
such security is valued at a price equal to the mean of the latest bid and ask
prices. All other securities and assets for which market quotations are not
readily available are valued at their fair value as determined in good faith
under procedures established by and under the general supervision of the Fund's
Board of Directors.

Other: Security transactions are accounted for on the date the securities are
purchased or sold. The cost (proceeds) of investments sold (bought to cover) are
determined on a specific identification basis for the purpose of determining
gains or losses on sales and buys to cover on short positions. Dividend income
and distributions to shareholders are recorded on the ex-dividend date. Interest
income is recorded on an accrual basis.

Use of Estimates: The preparation of financial statements in accordance with
accounting principles generally accepted in the United States of America
requires management to make estimates and assumptions that affect the reported
amounts and disclosures in the financial statements. Actual results could differ
from those estimates and those differences could be material.

3. INVESTMENT ADVISORY AND ADMINISTRATIVE SERVICES

The Fund has engaged Needham Investment Management L.L.C. (the "Adviser") to
manage its investments. The Fund pays the Adviser a fee at the annual rate of
1.25% of the average daily net asset value of each Portfolio.

The Adviser has voluntarily agreed to waive its fee for, and to reimburse
expenses of, the Fund in an amount that operates to limit annual operating
expenses for the six months ended June 30, 2003 to not more than 2.50% of
average daily net assets. For the six months ended June 30, 2003, the Adviser
waived advisory fees in the amount of $55,772 and $28,621 for NAGF and NSCGF,
respectively. The Adviser waived none of its fees for NGF during the six months
ended June 30, 2003. During the six months ended June 30, 2003, the Adviser also
reimbursed NSCGF for expenses in the amount of $52,180.

PFPC Inc. ("PFPC") acts as the Fund's Administrator. The Fund pays PFPC a fee at
the annual rate of 0.10% of the average daily net asset value of the Fund,
subject to certain minimums. PFPC also acts as the Fund's shareholder servicing
agent and transfer agent.

Certain officers and directors of the Fund are also officers and directors of
the Adviser.

4. FEDERAL INCOME TAXES

No provision for federal income taxes is required since the Fund intends to
continue to qualify as a regulated investment company under Subchapter M of the
Internal Revenue Code and distribute substantially all of its taxable income and
capital gains to shareholders. Because income tax regulations differ from
accounting principles generally accepted in the United States of America, the
timing and character of income and capital gain distributions determined in
accordance with tax regulations can differ from income and capital gains
recognized for financial reporting purposes. Accordingly, the character of
distributions and the composition of net assets for tax purposes can differ from
those reflected in the financial statements.

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

Notes to Financial Statements (Unaudited) (Continued)

These book/tax differences may be temporary or permanent in nature. To the
extent these differences are permanent, they are charged or credited to paid-in
capital, accumulated net realized gain (loss) or accumulated net investment
income (loss), as appropriate, in the period the differences arise. These
reclassifications have no effect on net assets or net asset value per share.

The components of distributable earnings on a tax basis do not differ materially
from book basis distributable earnings, which are disclosed in the Statements of
Assets and Liabilities.

During the year ended December 31, 2002, NGF, NAGF and NSCGF each reclassified
the current year's accumulated net investment loss to paid-in capital, in the
amounts of $3,495,249, $279,802 and $44,995, respectively.

Capital losses after October 31 ("post-October losses") within the taxable year
are deemed to arise on the first business day of the Portfolios' next taxable
year. After October 31, 2002, NGF, NAGF and NSCGF incurred and will elect to
defer net capital losses in the approximate amounts of $3,864,000, $131,000, and
$181,000, respectively.

At June 30, 2003, gross unrealized appreciation and depreciation for federal
income tax purposes of investment securities was in the following approximate
amounts:

5. TEMPORARY BORROWINGS

The Fund has entered into an agreement with the Custodial Trust Company for
temporary borrowing purposes, including the meeting of redemption requests that
otherwise might require the untimely disposition of securities. Interest is
calculated daily based on the Federal Funds Rate plus one percent. The Fund may
borrow from banks up to 25% of its total assets and may pledge its assets in
connection with these borrowings, provided that no additional investments shall
be made while borrowings exceed 5% of total assets. During the six months ended
June 30, 2003, borrowings were as follows:

6. DISTRIBUTION PLAN

The Fund has adopted a Distribution Plan pursuant to Rule 12b-1 under the
Investment Company Act of 1940. Under the plan, the Fund pays Needham & Company,
Inc. and any other distributor or financial institution with which the Fund has

8. OPTION TRANSACTIONS

The Portfolios may write call and put options on securities they own or have the
right to acquire, and may purchase put and call options on individual securities
and indices written by others. Put and call options give the holder the right to
sell or purchase, respectively, a specified amount of a security at a specified
price on a certain date.

The Portfolios are subject to market risk associated with changes in the value
of the underlying financial instrument, as well as the risk of loss of
appreciation if a counterparty fails to perform. For exchange-traded contracts,
the exchange acts as the counterparty to specific transactions, and therefore,
bears the risk of delivery to and from counterparties of specific positions.

Put and call options purchased are accounted for in the same manner as portfolio
securities. The cost of securities acquired through the exercise of call options
is increased by the premium paid. The proceeds from securities sold through the
exercise of put options are decreased by the premiums paid. Options on stock
indices differ from options on securities in that the exercise of an option on a
stock index does not involve delivery of the actual underlying security and is
settled in cash only. Call and put options purchased at June 30, 2003 and their
related market values are included in the accompanying Schedules of Investments.

When a Portfolio writes an option, the premium received by the Portfolio is
recorded as a liability and is subsequently adjusted to the current market value
of the option written. Premiums received from writing options which have expired
are recorded by the Portfolio on the expiration date as realized gains from
option transactions. When a Portfolio enters into a closing purchase
transaction, the Portfolio realizes a gain or loss equal to the difference
between the cost of a closing purchase transaction and the premium received when
the option was written. If an option is exercised, the premium is added to the
proceeds from the sale of the underlying security in determining whether the
Portfolio has a realized gain or loss. In writing an option, the Portfolio bears
the market risk of an unfavorable change in the price of the security underlying
the written option.

Notes to Financial Statements (Unaudited) (Continued)

9. SHORT SALE TRANSACTIONS

During the six months ended June 30, 2003, the Portfolios sold securities short.
An equivalent amount of securities owned by the Portfolios are segregated as
collateral while the short sales are outstanding. At June 30, 2003, the market
value of securities separately segregated to cover short positions was
approximately $103,176,000, $2,856,000 and $385,000 for NGF, NAGF and NSCGF,
respectively. For financial statement purposes, an amount equal to the
settlement amount is included in the accompanying Statements of Assets and
Liabilities as an asset and an equivalent liability. The amount of the liability
is subsequently marked- to-market to reflect the current value of the short
position. Securities sold short at June 30, 2003 and their related market values
and proceeds are set forth in the accompanying Schedules of Securities Sold
Short.

10. FINANCIAL INSTRUMENTS

The Fund has always maintained a policy of valuing its securities positions and
derivative instruments at market values or estimated fair values and of
including any realized gains or losses in income.

In the normal course of its business, the Portfolios may trade various financial
instruments with off-balance sheet risk. These financial instruments include
securities sold short and exchange traded options. Generally, these financial
instruments represent future commitments to purchase or sell other financial
instruments at specific terms at specified future dates. Each of these financial
instruments contains varying degrees of off-balance sheet risk whereby changes
in the market values of the securities underlying the financial instruments may
be in excess of the amounts recognized in the financial statements.

Securities sold short represent obligations of the Portfolios to make future
delivery of specific securities and, correspondingly, create an obligation to
purchase the securities at market prices prevailing at the later delivery date
(or to deliver the securities if already owned by the Portfolios). As a result,
short sales create the risk that the Portfolios' ultimate obligation to satisfy
the delivery requirements may exceed the amount of the proceeds initially
received on the liability recorded in the financial statements.

                                                                              37
