                           Letter from the Chairman

Dear Strong Investor,

The United States' economic miracle continues to set records for longevity.
Today, we enjoy a near-perfect economy. How in the world did we get here?

In the days of our grandparents and great-grandparents, the railroad helped
drive the Industrial Revolution. Nearly every aspect of the Industrial
Revolution directly impacted and improved people's lives. Today, the
technological revolution is similarly impacting our lives. We feel its presence
every time we dial a cell phone, pull out a PalmPilot, boot up a computer, and
punch "play" on the CD player in the dashboard of our computer-programmed cars.
Technology is our constant companion.

Aside from those tangible ways in which we employ technology each and every
day, ongoing technological developments affect us in another, less obvious way.
The technology revolution is enhancing worker productivity, enabling the economy
to grow faster than ever before without the drag of inflation. This allows real
wages to rise faster than in previous periods of expansion, raising nearly
everyone's standard of living.

The phenomenal economic growth and wealth creation that we have experienced has
powered the financial markets to ever-higher levels in recent years. As long as
this favorable economic environment prevails -- and assuming that there isn't a
negative policy change or an economic "accident" to derail it -- our economy
should continue to expand. Hopefully, the financial markets will continue to
reflect that.

Despite the good times, we should never forget that the financial markets are in
control and that they are a discounting mechanism, continually peering into the
future. In fact, many experienced investors believe that certain sectors of the
financial markets are currently priced to perfection and any little hiccup could
cause a significant correction.

The U.S. Federal Reserve Board has increased interest rates six times during the
last 18 months in an attempt to slow the economy. Many central banks around the
world have been making a concerted effort to slow their economies. If one or
more of these economies should slow, it may be reflected in the tone of our
economy and financial markets as well. If that happens, 2000 could be the first
time in many years that investors earn a negative return on their stock
investments. It will be a new -- and unpleasant -- experience for investors
who know only the unbridled bull markets of the 1990s.

Financial markets are cyclical. A market correction, though painful, is as
natural as breathing. Financial volatility can significantly derail an
investment program, especially if that program is not carefully planned. At
Strong, we pride ourselves on helping our investors invest wisely and with
purpose. We advise you to establish a clear set of goals, a plan to reach them,
and a program of constant monitoring to make certain you are heading in the
right direction.

                                                     /s/ Dick

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

Fund highlights

 .    For the six months ended June 30, 2000, the Fund posted a return of 0.44%,
     while the Russell 2000(R) Index returned 3.04%./1/,*

 .    The Fund's performance was most influenced during this period by our
     positions in energy, cyclical, and technology stocks.

 .    Technology stocks were particularly volatile over the period. We are still
     being selective in this sector, as many valuations remain high and could be
     subject to a future correction.

Perspectives from the Manager

/s/ Richard Trent Weiss

Richard Trent Weiss
Portfolio Manager

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

Over the first six months of the year, the Fund's positions in energy, cyclical,
and technology stocks had the most impact on performance. Energy stocks such as
EOG Resources sustained their solid performance as OPEC was able to limit the
supply of oil in the international market. The price of natural gas also rose to
record levels as production failed to grow to expected levels. We have begun to
reduce our overweight position in the energy sector as both valuations and
fundamentals appear to be reaching a peak.

Technology and cyclical stocks were volatile over the period. Despite the
turmoil, select names helped drive the Fund's performance. Stocks such as I2
Technologies continued to benefit as companies upgraded their electronic
infrastructure. Many tech stocks remain overvalued, however, so we are still
being especially careful about our selections in this area. It appears that some
technology names may be due for further correction.

In another area, industrial names like Hussman International benefited from
consolidation and a continued strong economic backdrop. We slightly sold off
some of our positions within this area.

Two sectors that lagged during the first half of the year were retail and
media/telecom. Retail stocks suffered from growing concern regarding the impact
of continued rate increases by the Federal Reserve Board on consumers. It
appears to many that an economic slowdown

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

                                We believe the
                             next six months will
                               continue to show
                               a strengthening
                                in smaller-cap
                              stocks relative to
                              larger-cap stocks.

is imminent, but we do not believe that the economy is headed for a recession.
To us, the retail sector has therefore become more appealing, as negative market
sentiment has driven valuations down to attractive levels. We added slightly to
this sector. In the media/telecom sector, a slowdown in merger and acquisition
activity, combined with investor skittishness about a possible deceleration in
growth, kept the stocks under pressure. We remain optimistic that convergence
and consolidation will continue in the sector, however, and have taken the
weakness in the sector as an opportunity to add to positions.

We believe the next six months will continue to show a strengthening in smaller-
cap stocks relative to larger-cap stocks. Continued high valuations in large-cap
growth stocks present the market with limited opportunities to fuel continued
strong performance. Smaller stocks, as well as those in such forgotten sectors
as industrials, present the most compelling investment opportunities.
Additionally, a probable end to the Federal Reserve's rate hikes could rekindle
interest in economically sensitive stocks. Thus, we have been adding names in
the industrial and consumer cyclical sectors.

We thank you for investing in the Strong Common Stock Fund and look forward to
continuing to help you achieve your financial goals.

Your Fund's
approach

The Strong Common Stock Fund seeks capital growth. It invests at least 65% of
its assets in stocks of small- and medium-capitalization companies that the
Fund's manager believes are underpriced, yet have attractive growth prospects.
The manager bases his analysis on a company's "private market value" -- the
price an investor would be willing to pay for the entire company given its
management, financial health, and growth potential. He determines a company's
private market value based on a fundamental analysis of a company's cash flows,
asset valuations, competitive situation, and franchise value.

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

Market
highlights

 .  In addition to technology stocks, cyclicals were also volatile, as investors
   feared these issues could feel a negative impact if the Federal Reserve
   succeeds in slowing the rate of economic growth.

 .  Two sectors that lagged during the first half were retail and media/telecom.
   Retail stocks were also affected by concerns over the impact of a possibly
   slowing economy.

 .  Although the market reflects worry than an economic slowdown is imminent, we
   do not believe that the economy is headed for a recession.

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

The Fund's excellent start in 2000 versus the Russell 2000(R) Index was
primarily due to two factors:

  .  Solid stock selection. We had a number of strong performing stocks,
     including Pinnacle Holdings. Additionally, during this same period there
     were very few problem stocks.

  .  Controlled exposure to technology stocks. While we made adjustments last
     year to boost the Fund's technology holdings, we were careful to limit our
     overall exposure to technology and to keep the Fund well diversified. This
     discipline helped to protect the portfolio during the severe correction in
     technology stocks that took place in March through May, while still
     allowing us to tap some of America's leading growth companies.

In summary, we are pleased by our recent investment performance. Over the last
12 months, the Fund is up 23.48% versus 14.32% for our benchmark. Through
careful analysis and stock selection, we feel the Fund is on the right track and
poised to deliver above-benchmark returns.

Effective August 31, 2000, Charles "Chip" Paquelet will assume sole portfolio
management responsibility for the Fund.

                             YOUR FUND'S APPROACH

The Strong Discovery Fund seeks capital growth. It invests in securities that
its managers believe offer attractive opportunities for growth. The Fund usually
invests in a diversified portfolio of common stocks from small-, medium-, and
large-capitalization companies. These are chosen through a combination of in-
depth fundamental analysis of a company's financial reports and direct, on-site
research during company visits. When the managers believe market conditions
favor fixed-income investments, they have the flexibility to invest a
significant portion of the Fund's assets in bonds. The Fund would primarily
invest in intermediate - and long-term investment-grade bonds.

                               MARKET HIGHLIGHTS

 . The American economy continues its miraculous economic growth. Over time, the
  U.S. stock market should continue to reflect these favorable economic
  conditions should they continue.

 . The Russell 2000(R) Index is the major market index that tracks the
  performance of stocks most similar to the companies favored by the Fund.
  Internally, we have always used this index as a performance guide, but we
  formally replaced the S&P 500 Index with the Russell 2000(R) Index in our
  shareholder reports at the end of 1998.*

Perspectives from the Manager

Portfolio Manager

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

The Fund posted a solid first half of the year, beating its indexes. We made a
wise move in mid-March, when we reduced the Fund's exposure to the technology
sector because many of those securities had reached valuations that approached
their intrinsic value--that is, the price we believe a purchaser would be
willing to pay to buy the entire company. The fund also benefited from its
holdings in natural resource producers and the oil industry service providers,
as the prices of oil and natural gas rose substantially.

The period can best be described in one word--"volatile." Since January 1, the
Nasdaq Composite Index, a good proxy for the technology sector, rose by 25%
through early March, declined 36% from that point through late May, and
subsequently recovered 23% through June 30. This extreme volatility surprised
even the most experienced investors. The increasing importance of the individual
investor in setting marginal prices, the collapse in the average holding period
of technology stocks, and the melding of the new economy and the old economy are
all relatively permanent factors increasing the technology sector's volatility
as well as that of the overall market.

With more than $1 trillion invested in online and discount brokerage accounts,
the behavior of the individual investor is becoming more instrumental in setting
stock prices than ever before. A recent study suggests that over the past 10
years, the amount of time it takes for the total outstanding shares of a
technology

company to change hands has fallen from more than one year to just four
months. In addition, as the Internet pervades many aspects of our lives and
supplants many successful businesses of today while enhancing the success of
others, the market will struggle to determine the winners and losers and reward
their stock prices accordingly--changing its mind many times in the interim.

Focusing on the relatively stable calculation of intrinsic value based on
economic cash flows (as opposed to accounting earnings), our strategy is to take
advantage of the market volatility and invest in those companies improving their
returns on invested capital when their stock prices are sufficiently lower than
their intrinsic value. While volatility can be disconcerting at times, it also
presents opportunities. We are attempting to take advantage of the increased
volatility by shortening our holding periods slightly and using our intrinsic-
value framework to highlight current market mispricings.

As always, we thank you for your investment and offer our best wishes to you and
your family.

Your Fund's
approach

The Strong Mid Cap Disciplined Fund seeks capital growth. It invests at least
65% of its assets in stocks of medium-capitalization companies that the Fund's
manager believes present attractive opportunities, but have not been widely
recognized by investment analysts or the financial press. The Fund defines
"medium-capitalization companies" as companies with a market capitalization
substantially similar to that of companies in the S&P MidCap 400 Index at the
time of investment. To identify these companies, the manager engages in in-
depth, first-hand research. On-site visits with members of a company's
management team are often an integral part of this process. The goal of the
manager's research is to identify companies that are undervalued or have growth
potential that is not currently reflected in the companies' stock prices.

Market
highlights

 .  Mid-cap stocks performed very well over the period, topping both the large-
   and small-capitalization sectors. On the margin, investors seem to be moving
   away from the large-cap growth favorites of the past few years into the mid-
   cap arena.

 .  While the Federal Reserve continues to address concerns regarding possible
   inflationary pressures from low unemploymentrates, the economy has shown
   signs of moderation, causing the Board to pause and observe.

 .  The technology sector performed extraordinarily well early in the period,
   corrected significantly, and then partially recovered, exhibiting the
   increased volatility that has characterized the market recently.

Technology remains the Fund's largest single sector, consuming roughly half the
Fund's assets. We continue to focus our investments on the direct beneficiaries
of the networked economy. Within the mid-cap universe, the fastest growth rates
continue to be produced by leading technology companies enjoying the positive
benefits of new product cycles. This growth is also buttressed by the need of
corporations to enhance productivity to compete in a global economy. With
relative valuations of technology companies at extreme levels, we have reduced
our weighting in the sector relative to prior periods.

Although we believe the Fed has now moved to a neutral bias, signs of continued
strong growth in the coming months may trigger further tightening action. With
valuations in the technology area at high historical levels and the market's
overall technology weighting at record highs, we expect volatility to remain
high. It is our assessment that careful stock picking and more diversified
sector weightings will be rewarded.

Healthcare is an area of renewed emphasis for us. Although the race to map the
human genome is now over, the hard work is really just beginning. We
particularly like the companies that provide the "picks and shovels" of genomic
discovery. We have also invested in several drug distribution companies, as we
believe a possible government prescription program could drive incremental unit
growth in the sector.

We believe the Federal Reserve's tightening cycle is near an end. Therefore,
consumer cyclicals are becoming increasingly attractive. We continue to
overweight category-killer retailers (Best Buy), unit growth stories (Kohl's),
and well-established consumer franchises (Tiffany). Another area we like, and to
which we added in the portfolio, is energy. Oil prices are high, OPEC members
are more than 90% compliant with production quotas, and economic conditions in
Asia appear to have stabilized. Finally, our careful selection of new issues
available in the market over the past six months also helped the performance of
the Fund.

As we assess the next six months, we expect the U.S. economy to grow at a more
moderate rate. Well-positioned growth companies able to generate unit growth, as
overall corporate profit growth begins to decelerate, will become increasingly
scarce. Fortunately, mid-cap stocks are often pure plays on dynamic niche
markets, new products, or innovative new services. Their fortunes are not as
closely tied to general economic factors as are those of larger companies. As
growth investors, our investment team is constantly on the lookout for companies
exhibiting sustainable fundamental improvement.

We thank you for your interest in the Strong Mid Cap Growth Fund and look
forward to continuing to help you address your financial goals.

The Strong Mid Cap Growth Fund seeks capital growth. It invests at least 65% of
its assets in stocks of medium-capitalization companies that the Fund's managers
believe have favorable prospects for accelerating growth of earnings but are
selling at reasonable valuations based on earnings, cash flow, or asset value.
The Fund defines "medium-capitalization companies" as companies with a market
capitalization substantially similar to that of companies in the S&P MidCap 400
Index at the time of investment. The Fund writes put and call options.

Market
Highlights

 . After several years of unusually strong performance for technology-related
  issues, the difference between the returns of technology stocks and those of
  other growth stocks began to close.

 . The Federal Reserve's interest-rate hikes in the face of a strong domestic
  economy, heightening inflationary pressures, and signs of economic strength
  overseas has helped to spur market volatility. Signs of continued strong
  growth in the coming months may trigger further tightening action.

 . High levels of corporate profitability continued to indirectly support the
  technology sector. Despite their recent correction, the relative valuations
  of new economy companies remain extremely rich.

Perspectives from the Manager


/s/ Scott Sindelar

Scott Sindelar
Portfolio Manager

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

Early in the year, we pared back the Fund's technology holdings, after their
strong performance in 1999 had allowed them to take up a larger percentage of
the portfolio than we desired. Among the positions we sold off were
Oracle, Telcomm Semiconductor, and CITRIX Systems; other tech holdings were
reduced.

As the first quarter progressed, however, tech stocks performed well and it
became apparent that the first-quarter results for tech companies would
generally be better than expected. In response to these favorable developments,
we added once again to our tech weighting--only to have the sector sell off
shortly thereafter.

As earnings were reported, technology's strength was evident, as most companies
reported strong results and managements often spoke of strong business trends.
However, for tech companies, we thought that trends may be a short-term
phenomenon if tech stocks continued to decline. In an effort to moderate the
Fund's volatility, we then reduced the tech weighting, though we retained some
holdings, such as Audiocodes, Netopia, and TUT Systems to continue participating
in high-growth areas. We reallocated assets to consumer, healthcare, and
financial stocks, which helped the Fund gain ground in June.

The Fund's consumer, finance, health services, and energy sectors provided good
relative returns for the first six months. The Fund's

increased exposure to the energy sector via Royal Dutch Shell proved
beneficial. Several industry leaders, including Safeway, American International
Group, and General Electric were also solid performers. Smaller companies
contributing to the Fund's performance included C.H. Robinson, Medquist, and
Concord EFS.

The economy remains strong but appears to be slowing, albeit from historically
high levels. The Federal Reserve may raise interest rates again, but probably
not to the point of significantly impairing the economy. The equity markets are
likely to continue to be volatile. To contend with this environment, the
portfolio is currently well-diversified, populated by companies that appear to
have both good long-term outlooks and solid cash-flow characteristics.

Thank you for your faith in the Strong Strategic Growth Fund. We hope to provide
you with solid long-term results.

Your Fund's
approach

The Strong Strategic Growth Fund seeks capital growth. It invests primarily in
the stocks of medium- and large-capitalization companies, looking for those that
may have long-term growth potential. Based on fundamental analysis, the Fund's
manager seeks stocks of well-managed companies that produce needed or proven
products (products for which there is a significant or growing demand in the
marketplace) and that are market leaders in growing industries. In looking for
well-managed companies, the manager examines many factors such as consistency of
a business plan, foresight of the competitive market conditions, business
knowledge, and management's attention to detail. The portfolio generally holds
50 or fewer stocks.

Market
highlights

 .   Technology stocks had a roller-coaster ride during the first six months,
    climbing over 20% during the first half of the period, then falling by more
    than 33%. They subsequently recovered, ending the period down slightly from
    where they started.

 .   Volatility was present in all equity markets as a tug-of-war continued
    between further strong corporate profitability and concerns over both
    valuations and fears of a slowing economy.

 .   The Federal Reserve continued its watch on the inflation front, raising
    interest rates further during the first half of the year.

Perspectives from the Manager

Portfolio Manager

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

The Strong Growth Fund continued to outperform the S&P 500 Index for the first
half of the year 2000 (8.41% versus-0.42%)./3,/* Our investment process remains
focused on investments in high-quality, well-managed growth companies within the
most dynamic industries regardless of market capitalization.

Despite the volatility in the overall market this year, we continue to believe
that the leaders of the new economy provide the best opportunities for long-term
growth. These companies are delivering revolutionary products and services to
garner market share, or in some cases, create whole new markets and industries.
We expect these firms to generate superior shareholder returns by sustaining
superior earnings growth and returns on invested capital. While most of these
companies are in the technology, telecommunications, or biotech industries, we
are still finding many attractive growth opportunities in more mundane areas of
the economy, including retail, media, energy, and financial services.

Two of our long-time holdings, JDS Uniphase and Kohl's Department Stores, were
big winners for the Fund over the past six months. They are prime examples of
the types of companies in which we like to invest. JDS Uniphase is the world
leader in producing optical networking technologies for the telecommunications
industry. Its products are essential components to the growth of the Internet
and bandwidth expansion. Through unique innovations and

timely acquisitions, JDS Uniphase has positioned itself as the premier arms
maker to those who battle for dominance in the Internet and telecommunications
fields.

In contrast, Kohl's Department Stores, based in Menomonee Falls, Wisconsin, is
in the low-tech business of providing brand-name goods in a more convenient and
inexpensive format. Kohl's is stealing significant market share from its older
department store competitors as it rolls out new stores across the United
States.

What these two otherwise disparate companies have in common is that their
managements have both consistently executed well-defined business plans. We
expect them to continue to do so.

Our market outlook for the remainder of the year is optimistic, given the
apparent slowdown of the U.S. economy from its red-hot pace. Although it appears
the Federal Reserve is close to ending its course of raising interest rates, we
expect the Fed to be aggressive should any real evidence of inflation appear on
the horizon.

We thank you for investing in the Strong Growth Fund as we do our best to help
you achieve your financial goals.

Your Fund's
approach

The Strong Growth Fund seeks capital growth.  It focuses on stocks of companies
that its manager believes have favorable prospects for accelerating growth of
earnings but are selling at reasonable valuations based on earnings, cash flows,
or asset value.  The portfolio can include stocks of any size.  The Fund writes
put and call options.

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

Market
highlights

 .    After several years of unusually strong performance for technology-related
     issues, the gap between the returns of technology companies and those of
     other growth companies began to close during the first six months of 2000,
     particularly in the second quarter.

 .    By raising short-term interest rates in the face of a strong domestic
     economy, heightening inflationary pressures, and signs of economic strength
     overseas, the Federal Reserve helped to spark market volatility in the
     first half of the year.

 .    Signs of continued strong growth in coming months may trigger further
     tightening action, and we expect volatility to continue.

 .    High levels of corporate profitability continue to indirectly support the
     technology sector.

Fund highlights

 .    The Fund's performance was driven primarily by its holdings in technology,
     energy, and healthcare.

 .    As investors turned wary of technology stocks in April and May, more
     defensive growth companies came to the fore. Our holdings in this arena,
     particularly Corning and American Power Conversion, were strong performers
     for the Fund. We were able to hold these securities during this period and
     reap the benefits.

Perspectives from the Manager


/s/ Richard Trent Weiss

Richard Trent Weiss
Portfolio Manager

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

From January through June of this year, holdings in the technology, energy, and
healthcare sectors drove the Fund's performance. The Nasdaq's precipitous drop
in April and May drove many investors to other areas of the market, allowing old
economy stocks to enjoy a period of healthier performance. Nonetheless, many
technology stocks continue to have high valuations--particularly after the
sector's partial recovery in June. As a result, we are still being very careful
about our selections in this area.

In the energy sector, supply constraints pushed crude oil and natural gas prices
to very high levels; the prices of energy-related stocks, such as fund holding
Weatherford International, followed suit. It's our assessment that many oil
stocks are at or near their peaks, so we have begun to trim our positions in
this area.

Healthcare generally performed well over the period, as investors looked for
more defensive alternatives in the face of the high volatility of technology
stocks. In this environment, we chose to add some health stocks to the
portfolio, including Watson Pharmaceuticals. We still find the growth prospects
of the sector appealing, but the recovery in the sector during the spring pushed
some stocks toward their valuation targets.

Concerns about possible economic slowing that could result from the Federal
Reserve's interest-rate hikes have driven the prices of many industrial and
consumer cyclical stocks down, making them increasingly attractive as buying

opportunities. We have added high-quality names with strong franchises such as
Masco Corporation and Raytheon to the portfolio.

Reduced merger and acquisition activity, along with economic concerns, kept
media and telecom stocks under pressure. We remain optimistic, however, that
convergence and consolidation will continue in this sector and have, therefore,
chosen to take the current weakness in the sector as an opportunity to add to
positions.

The high valuations of large-cap growth stocks present the market with limited
opportunities to fuel continued strong performance. This creates an environment
that should be favorable to our investment approach, as it appears that smaller
stocks and stocks that focus on forgotten sectors now present the most
interesting investment opportunities. Areas in which we are adding to our
holdings include industrials and consumer cyclicals, as the impending end of the
Fed's interest-rate hikes could benefit these sectors.

We thank you for investing in the Strong Opportunity Fund and look forward to
continuing to help you pursue your financial goals.

This graph, provided in accordance with SEC regulations, compares a $10,000
investment in the Fund, made at its inception, with the performance of the
Standard & Poor's MidCap 400 Stock Index ("S&P MidCap 400") and the Lipper
Multi-Cap Value Funds Index. Results include the reinvestment of all dividends
and capital gains distributions. Performance is historical and does not
represent future results. Investment returns and principal value vary, and you
may have a gain or loss when you sell shares. This graph is based on Investor
Class shares only; performance for other classes will vary due to differences in
fee structures.

Your Fund's
approach

The Strong Opportunity Fund seeks capital growth. It invests primarily in stocks
of medium-capitalization companies that the Fund's manager believes are
underpriced, yet have attractive growth prospects. He bases his analysis on a
company's "private marketvalue"--the price an investor would be willing to pay
for the entire company given its management, financial health, and growth
potential. The manager determines a company's private market value based on a
fundamental analysis of a company's cash flows, asset valuations, competitive
situation, and franchise value.

Market
highlights

 .    S&P MidCap 400 Stock Index, the Fund's benchmark, returned 8.97% for the
     first six months of 2000.

 .    Technology proved to be a precarious sector, with the Nasdaq Composite
     Index dropping by more than 13% in the second quarter of the year.

 .    Cyclicals, along with media and telecommunications stocks, suffered in the
     first half of the year. This was the result of worries about a possible
     slowdown in the economy.

NOTES TO FINANCIAL STATEMENTS
--------------------------------------------------------------------------------
June 30, 2000 (Unaudited)

1.  Organization

    The accompanying financial statements represent the Strong Growth Funds (the
    "Funds"), which include the following funds, each with its own investment
    objectives and policies:

    - Strong Common Stock Fund, Inc./(1)/
    - Strong Discovery Fund, Inc./(1)/
    - Strong Mid Cap Disciplined Fund (a series of Strong Equity Funds,
      Inc./(1)/)
    - Strong Mid Cap Growth Fund (a series of Strong Equity Funds, Inc./(1)/)
    - Strong Strategic Growth Fund (a series of Strong Equity Funds, Inc./(1)/)
    - Strong Growth Fund (a series of Strong Equity Funds, Inc./(1)/)
    - Strong Opportunity Fund, Inc./(1)/

      /(1)/ A diversified, open-end management investment company registered
    under the Investment Company Act of 1940, as amended.

    Strong Mid Cap Disciplined Fund commenced operations on January 4, 1999.

    Effective February 25, 2000, the Strong Opportunity Fund has issued two
    classes of shares: Investor Class and Advisor Class. The Strong Growth Fund
    has issued three classes of shares: Investor Class, Institutional Class and
    Advisor Class. The Advisor Class shares are subject to an annual
    distribution fee as described in Note 3. Each class of shares has identical
    rights and privileges except with respect to voting rights on matters
    pertaining to that class. Income, expenses (other than expenses attributable
    to a specific class), and realized and unrealized gains or losses on
    investments are allocated to each class of shares based on its relative net
    assets.

2.  Significant Accounting Policies

    The following is a summary of significant accounting policies followed by
    the Funds in the preparation of their financial statements.

    (A)   Security Valuation -- Securities of the Funds are valued at fair value
          through valuations obtained by a commercial pricing service or the
          mean of the bid and asked prices when no last sales price is
          available. Securities for which market quotations are not readily
          available are valued at fair value as determined in good faith under
          consistently applied procedures established by and under the general
          supervision of the Board of Directors. Securities which are purchased
          within 60 days of their stated maturity are valued at amortized cost,
          which approximates fair value.

          The Funds may own certain investment securities which are restricted
          as to resale. These securities are valued after giving due
          consideration to pertinent factors, including recent private sales,
          market conditions and the issuer's financial performance. The Funds
          generally bear the costs, if any, associated with the disposition of
          restricted securities. Aggregate acquisition cost and fair value of
          these restricted securities held at June 30, 2000 were as follows:

                                  Aggregate      Aggregate     Percent of
                                    Cost         Fair Value    Net Assets
                                  ---------      ----------    ----------
          Strong Discovery Fund    $621,989       $192,076         0.1%

    (B)   Federal Income and Excise Taxes and Distributions to Shareholders --
          The Funds intend to comply with the requirements of the Internal
          Revenue Code applicable to regulated investment companies and to
          distribute substantially all of their taxable income to their
          shareholders in a manner which results in no tax cost to the
          Funds. Therefore, no federal income or excise tax provision is
          required.

          Net investment income or net realized gains for financial statement
          purposes may differ from the characterization for federal income tax
          purposes due to differences in the recognition of income and expense
          items for financial statement and tax purposes. Where appropriate,
          reclassifications between net asset accounts are made for such
          differences that are permanent in nature.

          Each Fund generally pays dividends from net investment income and
          distributes any net capital gains that it realizes annually.

     (C)  Realized Gains and Losses on Investment Transactions -- Investment
          security transactions are recorded as of the trade date. Gains or
          losses realized on investment transactions are determined by comparing
          the identified cost of the security lot sold with the net sales
          proceeds.

     (D)  Certain Investment Risks -- The Funds may utilize derivative
          instruments including options, futures and other instruments with
          similar characteristics to the extent that they are consistent with
          the Funds' investment objectives and limitations. The Funds intend to
          use such derivative instruments primarily to hedge or protect from
          adverse movements

38
<PAGE>

          in securities prices or interest rates. The use of these instruments
          may involve risks such as the possibility of illiquid markets or
          imperfect correlation between the value of the instruments and the
          underlying securities, or that the counterparty will fail to perform
          its obligations.

          Investments in foreign denominated assets or forward currency
          contracts may involve greater risks than domestic investments due to
          currency, political, economic, regulatory and market risks.

    (E)   Futures -- Upon entering into a futures contract, the Funds pledge to
          the broker cash or other investments equal to the minimum "initial
          margin" requirements of the exchange. Additional securities held by
          the Funds may be designated as collateral on open futures contracts.
          The Funds also receive from or pay to the broker an amount of cash
          equal to the daily fluctuation in the value of the contract. Such
          receipts or payments are known as "variation margin" and are recorded
          as unrealized gains or losses. When the futures contract is closed, a
          realized gain or loss is recorded equal to the difference between the
          value of the contract at the time it was opened and the value at the
          time it was closed.

    (F)   Options -- The Funds may write put or call options. Premiums received
          by the Funds upon writing put or call options are recorded as an asset
          with a corresponding liability which is subsequently adjusted to the
          current market value of the option. Changes between the initial
          premiums received and the current market value of the option are
          recorded as unrealized gains or losses. When an option expires, is
          exercised, or is closed, the Funds realize a gain or loss, and the
          liability is eliminated. The Funds continue to bear the risk of
          adverse movements in the price of the underlying asset during the
          period of the option, although any potential loss during the period
          would be reduced by the amount of the option premium received.
          Securities held by the Funds may be designated as collateral on
          written options.

    (H)   Foreign Currency Translation -- Investment securities and other assets
          and liabilities initially expressed in foreign currencies are
          converted daily to U.S. dollars based upon current exchange
          rates. Purchases and sales of foreign investment securities and income
          are converted to U.S. dollars based upon currency exchange rates
          prevailing on the respective dates of such transactions. The effect of
          changes in foreign exchange rates on realized and unrealized security
          gains or losses is reflected as a component of such gains or losses.

    (H)   Forward Foreign Currency Exchange Contracts -- Forward foreign
          currency exchange contracts are valued at the forward rate and are
          marked-to-market daily. The change in market value is recorded as an
          unrealized gain or loss. When the contract is closed, the Funds record
          an exchange gain or loss equal to the difference between the value of
          the contract at the time it was opened and the value at the time it
          was closed.

    (I)   Repurchase Agreements -- The Funds may enter into repurchase
          agreements with institutions that the Funds' investment advisor,
          Strong Capital Management, Inc. ("the Advisor"), has determined are
          creditworthy pursuant to criteria adopted by the Board of Directors.
          Each repurchase agreement is recorded at cost. The Funds require that
          the collateral, represented by securities (primarily U.S. Government
          securities), in a repurchase transaction be maintained in a segregated
          account with a custodian bank in a manner sufficient to enable the
          Funds to obtain those securities in the event of a default of the
          repurchase agreement. On a daily basis, the Advisor monitors the value
          of the collateral, including accrued interest, to ensure it is at
          least equal to the amounts owed to the Funds under each repurchase
          agreement.

    (J)   Use of Estimates -- The preparation of financial statements in
          conformity with generally accepted accounting principles requires
          management to make estimates and assumptions that affect the reported
          amounts in these financial statements. Actual results could differ
          from those estimates.

    (K)   Other -- Dividend income and distributions to shareholders are
          recorded on the ex-dividend date. Interest income is recorded on the
          accrual basis and includes amortization of premiums and discounts.

3.  Related Party Transactions

    The Advisor, with whom certain officers and directors of the Funds are
    affiliated, provides investment advisory, administrative, shareholder
    recordkeeping and related services to the Funds. Investment advisory and
    administrative fees, which are established by terms of the Advisory
    Agreements, are based on the following annualized rates of the average daily
    net assets of the respective Fund:

                                                                              39

     *  The Strong Common Stock Fund, Strong Discovery Fund, Strong Mid Cap

        Fund do not offer Institutional or Advisor Class Shares.

    **  The Strong Opportunity Fund does not offer Institutional Class shares.

   Based on the terms of the Advisory Agreements, advisory fees, administrative
   fees and other expenses will be waived or absorbed by the Advisor if the
   Fund's operating expenses exceed 2% of the average daily net assets of the
   Fund. In addition, the Fund's Advisor may voluntarily waive or absorb certain
   expenses at its discretion. Shareholder recordkeeping and related service
   fees are based on contractually established rates for each open and closed
   shareholder account. The Advisor also allocates to each Fund certain charges
   or credits resulting from transfer agency banking activities based on each
   Fund's level of subscription and redemption activity. Charges allocated to
   the Funds by the Advisor are included in Other Expenses in the Funds'
   Statement of Operations. Credits allocated by the Advisor serve to reduce the
   shareholder servicing expenses incurred by the Funds and are reported as Fees
   Paid Indirectly by Advisor in the Funds' Statement of Operations. The Advisor
   is also compensated for certain other services related to costs incurred for
   reports to shareholders.

   The Strong Growth Fund and Strong Opportunity Fund have entered into a
   distribution agreement with Strong Investments, Inc. (the "Distributor"),
   pursuant to Rule 12b-1 under the 1940 Act, on behalf of each of the Fund's
   Advisor Class shares. Under the agreement, the Distributor is paid an annual
   rate of 0.25% of the average daily net assets of the Advisor Class shares as
   compensation for services provided and expenses incurred, including amounts
   paid to brokers or dealers, in connection with the sale of each Fund's
   shares. During the period February 25, 2000 to June 30, 2000, the Strong
   Growth Fund and the Strong Opportunity Fund incurred 12b-1 fees of $17 and
   $39, respectively.

   The Funds may invest cash in money market funds sponsored and managed by the
   Advisor, subject to certain limitations. The terms of such transactions are
   identical to those of non-related entities except that, to avoid duplicate
   investment advisory fees, advisory fees of each Fund are reduced by an amount
   equal to advisory fees paid to the Advisor under its investment advisory
   agreement with the money market funds.

   Certain information regarding related party transactions, excluding the
   effects of waivers and absorptions, if any, for the six months ended June 30,
   2000, is as follows:

5.   Line of Credit

     The Strong Funds have established a line of credit agreement ("LOC") with
     certain financial institutions to be used for temporary or emergency
     purposes, primarily for financing redemption payments. Combined borrowings
     among all participating Strong Funds are subject to a $350 million cap on
     the total LOC. For an individual Fund, borrowings under the LOC are limited
     to either the lesser of 15% of the market value of the Fund's total assets
     or any explicit borrowing limits in the Funds' prospectus. Principal and
     interest on each borrowing under the LOC are due not more than 60 days
     after the date of the borrowing. Borrowings under the LOC bear interest
     based on prevailing market rates as defined in the LOC. A commitment fee of
     0.08% per annum is incurred on the unused portion of the LOC and is
     allocated to all participating Strong Funds. At June 30, 2000, there were
     no borrowings by the Funds outstanding under the LOC.

                                                                              43
