                            LETTER FROM THE CHAIRMAN


Dear Strong Investor,

There is an old Wall Street saying that goes something like this: "Don't fight
the Fed." This is a basic rule you ignore at your own peril.

Since June of 1999, the Federal Reserve Board has raised short-term interest
rates five times with one goal in mind: to slow the economy. This past winter
and spring, the U.S. financial markets began to react to the Fed's actions
swiftly and dramatically. The speed and violence of the downdraft that followed
was enough to scare even the most seasoned investors.

What happened to the financial markets was capitalism doing what it does
best--separating the weak from the strong. Capitalism takes no prisoners. It has
an uncanny ability to seek out the excesses in the system and to separate
quality companies from deficient ones. To my way of thinking, that only serves
to underscore the importance of quality, balance, and diversification in a
portfolio. This spring's financial damage rather dramatically exposed the
excesses in technology and Internet investments and burst the bubble that had
formed around these sectors of the market.

Meanwhile, we are in the tenth year of an unprecedented economic expansion. A
large part of the credit for our good fortune belongs to Alan Greenspan's
shaping of monetary policy and the Fed's rather remarkable achievements in
managing interest rates. Under the current circumstances, the question most
investors need to ask is how to continue participating in the opportunities
available without exposing themselves to too much risk.

When I was a rookie in the investment business, an old-timer told me that too
many people treat investing as entertainment. Investing is not a game. It is a
vital component of the capitalist system. If you want to make your way through
the system without losing your shirt, you need to pick a specific financial
destination and get a reliable investment road map that will take you there.

A successful investment program involves finding companies with proven
management along with real products and services. In other words, invest in
people and companies who you are confident will do exactly what they say they
will do. Identifying them requires research, patience, and experience.

Investing is not a game of hot potato where you buy a stock, pray that the price
goes up, and then pass it to some poor soul when the price is on the way down.
That's not serious investing. That's more like a guarantee that someone--either
you or the next guy--is going to get burned.

                                                         /s/ Dick

FROM THE MANAGERS

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

During the past six months, the U.S. economy continued to be very strong,
spurred on by healthy domestic demand. The economy, measured by real GDP, posted
solid first-quarter growth at 5.4%, while consumption was up an even stronger
8%. With the fed funds target rate going up by 75 basis points, two- and
five-year Treasury yields increased by 86 and 57 basis points, respectively.

Throughout the period, we generally maintained an overweighting in U.S.
high-yield debt. This sector was not in favor, but superior issue selection--in
both the high-yield and higher-quality portions of the Fund--allowed us to
overcome that fact. We undertook an "up in quality" initiative within the
higher-grade portion of the Fund, which served the Fund well in the current
period.

The international portion of the Fund performed well. All currency exposure was
hedged back to U.S. dollars, thus avoiding the adverse consequences of a
generally weak currency market.

In January, the U.S. Treasury announced plans to repurchase long-maturity
government debt. This caused longer-maturity government bonds to be the
best-performing sector of the investment-grade market. Yields on 30-year bonds
declined by 20 basis points, despite the increase in short- and
intermediate-term interest rates. The yield curve has now become inverted, with
yields on two-year notes approximately 70 basis points higher than those on
30-year bonds.

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

WE EMPLOYED A BARBELL STRATEGY FOR THE FUND, EMPHASIZING LONG-MATURITY TREASURY
SECURITIES ALONG WITH SHORT- AND INTERMEDIATE-MATURITY CORPORATE
BONDS.

 HIGHLIGHTS

-    Short- and intermediate-term interest rates increased, while
     longer-maturity rates declined. The decline in long rates was, however,
     limited to the Treasury market.

-    We have reduced our overall portfolio duration and emphasized
     higher-quality securities when purchasing long-maturity bonds.

While corporate bonds typically play an important role in the Fund's ongoing
strategy, we maintained a meaningful position in long-maturity U.S. Treasuries
during the period. These holdings benefited from the Treasury's repurchase
activities.

We employed a barbell strategy for the Fund, emphasizing long-maturity Treasury
securities along with short- and intermediate-maturity corporate bonds. This
strategy added value because we participated in the strong performance of
longer-maturity government bonds and avoided some of the underperformance
experienced by the 30-year corporate bond market.


We expect that in the near term, the Fed will increase the fed funds rate by an
additional 50 to 75 basis points in order to slow economic growth and fend off
inflation. We anticipate that the Federal Reserve will continue its success in
containing any meaningful rise in inflation. Once it becomes clear that the Fed
has completed its rate hikes, we intend to adopt a more aggressive posture for
the portfolio with respect to both interest-rate and credit risk.

Thank you for your investment in the Strong Bond Fund. We appreciate the
confidence you have placed in us.

 APPROACH

THE STRONG BOND FUND SEEKS TOTAL RETURN BY INVESTING FOR A HIGH LEVEL OF CURRENT
INCOME WITH A MODERATE DEGREE OF SHARE-PRICE FLUCTUATION. THE FUND INVESTS
PRIMARILY IN HIGHER- AND MEDIUM-QUALITY CORPORATE, MORTGAGE- AND ASSET-BACKED,
U.S. GOVERNMENT, AND FOREIGN GOVERNMENT BONDS. THE FUND'S DURATION WILL NORMALLY
VARY BETWEEN THREE AND SIX YEARS. THE FUND MAY INVEST UP TO 20% OF ITS ASSETS IN
SECURITIES DENOMINATED IN FOREIGN CURRENCIES AND MAY INVEST BEYOND THIS LIMIT IN
U.S. DOLLAR-DENOMINATED SECURITIES OF FOREIGN ISSUERS. THE FUND MAY ALSO INVEST
UP TO 20% OF ITS ASSETS IN LOWER-QUALITY, HIGH-YIELD BONDS. IN SELECTING BONDS
FOR THE PORTFOLIO, THE MANAGERS ENGAGE IN RIGOROUS, SECURITY-BY-SECURITY

MARKET
 HIGHLIGHTS

-    The Federal Reserve Board raised the federal funds target rate by 75 basis
     points during the past six months in response to strong economic growth and
     a cyclical increase in inflation.

-    Increased budget surpluses led the U.S. Treasury to announce the planned
     repurchase of $30 billion of government debt.

-    Investment-grade bonds outperformed high-yield bonds. International bonds,
     when hedged to eliminate currency risk, outperformed U.S. domestic bonds.

-    The variance in returns among asset classes, sectors, and industries within
     the bond market has increased significantly over the past two years.

During the past six months, the U.S. economy continued to be very strong,
spurred on by very strong domestic demand. The economy, measured by real GDP,
posted solid first quarter growth at 5.4%, while consumption was up an even
stronger 8%. With the Central Bank raising the fed funds target rate by 75
basis points, two- and five-year Treasury yields increased by 86 and 57 basis
points, respectively.

In January, the U.S. Treasury announced a plan to repurchase long-maturity
government debt. This announcement caused longer-maturity government bonds to be
the best-performing sector of the investment-grade market. Yields on 30-year
bonds declined by 20 basis points, despite the increase in short- and
intermediate-term interest rates. The yield curve has now become inverted, with
yields on two-year notes approximately 70 basis points higher than those on
30-year bonds.

The combination of Fed tightening and Treasury debt buybacks led to the relative
underperformance of corporate bonds relative to government bonds. Fed tightening
caused investors to question the durability of the economic expansion and the
sustainability of earnings growth. The government debt buybacks hurt the
corporate market by heightening the distinction between Treasuries and the
corporate market: government supply is declining, while corporate bond supply is
now near record levels.

In this environment, we employed a barbell strategy for the Fund, emphasizing
long-maturity Treasury securities along with short- and intermediate-

FUND
 HIGHLIGHTS

-    Short- and intermediate-term interest rates increased, while
     longer-maturity Treasury rates declined.

-    Corporate bonds underperformed Treasury securities. The government's
     buyback of Treasury debt and a modest deterioration in corporate credit
     quality caused BBB and BB corporate bond yields to rise more than Treasury
     yields.

-    We have reduced our overall portfolio duration and emphasized
     higher-quality securities when purchasing long-maturity bonds.

maturity corporate bonds. This strategy added value because we participated in
the strong performance of longer-maturity government bonds and avoided some of
the underperformance experienced by the 30-year corporate bond market, the
worst-performing part of the corporate market.

We also increased shareholder returns through excellent credit selection
during the period. We were able to avoid investments in the worst-performing
companies and identify companies with improving fundamentals. Companies that
outperformed the market after seeing their credit ratings upgraded include Enron
and Cablevision.

We expect that in the near term, the Fed will increase the fed funds rate by an
additional 50 to 75 basis points in order to slow economic growth and
fend off inflation. Corporate bonds may lag Treasury returns as this occurs, but
corporate bond yields are at such attractive levels that these effects should be
largely mitigated by current income levels. We anticipate that the Fund will
adopt a more aggressive stance with respect to both interest-rate and credit
risk once it becomes clear that the Fed has completed its interest-rate hikes.

Thank you for your investment in the Strong Corporate Bond Fund. We appreciate
the confidence you have placed in us.

[SIDENOTE]
YOUR FUND'S
 APPROACH

THE STRONG CORPORATE BOND FUND SEEKS TOTAL RETURN BY INVESTING FOR A HIGH LEVEL
OF CURRENT INCOME WITH A MODERATE DEGREE OF SHARE-PRICE FLUCTUATION. THE FUND
INVESTS PRIMARILY IN INTERMEDIATE-MATURITY BONDS ISSUED BY U.S. COMPANIES. THE
FUND INVESTS PRIMARILY IN HIGHER- AND MEDIUM-QUALITY BONDS. TO INCREASE THE
INCOME IT PAYS OUT, IT MAY ALSO INVEST A SMALL PORTION OF ITS ASSETS IN
LOWER-QUALITY, HIGH-YIELD BONDS. THE MANAGERS FOCUS PRIMARILY UPON HIGH-YIELD
BONDS RATED BB WITH POSITIVE OR IMPROVING CREDIT FUNDAMENTALS. THE FUND'S
DOLLAR-WEIGHTED AVERAGE MATURITY WILL NORMALLY BE BETWEEN SEVEN AND TWELVE
YEARS. TO A LIMITED EXTENT, THE FUND MAY ALSO INVEST IN FOREIGN SECURITIES.

                     --------------------------------------
MARKET
 HIGHLIGHTS

-    The Federal Reserve Board raised the federal funds target rate by 75 basis
     points during the past six months in response to strong economic growth and
     a cyclical increase in inflation.

-    Increased budget surpluses led the U.S. Treasury to announce the planned
     repurchase of $30 billion of government debt.

-    The variance in returns among industries and companies within the
     corporate bond market has increased significantly in the past two years, as
     companies that disappoint bondholders now see the price of their debt
     decline more rapidly than in the past. This creates an excellent
     opportunity to add value through detailed company research.

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

Strong economic growth and continued wage pressures due to tight labor markets
led the Federal Reserve Board to raise the fed funds rate by 25 basis points on
each of three separate occasions over the past six months. These hikes pushed
other short-term Treasury rates higher, with the result that two-and five-year
Treasury rates rose by 86 and 57 basis points, respectively.

On the other end of the spectrum, a supply/demand imbalance caused yields to
decline in the long-maturity sector of the U.S. Treasury market. Treasury
Secretary Lawrence Summers announced the first-ever cash buyback of government
debt in January, focusing on longer-term debt. Furthermore, the Treasury
indicated that it would reduce the size of future 30-year debt auctions. These
actions created demand for long Treasuries while reducing their future supply.

To take advantage of these events, we employed what is referred to as a barbell
strategy in the Fund. This is accomplished by increasing exposure to the long
end of the yield curve (where demand is great and supply low) while holding
offsetting cash positions to avoid increasing the overall duration of the
portfolio. We positioned the Fund to have a duration shorter than the overall
market during the past six months.

Recent economic releases have indicated that U.S. GDP continued to grow at a
robust rate

WE BELIEVE THE FUND'S NON-TREASURY HOLDINGS CURRENTLY OFFER COMPELLING INCOME
OPPORTUNITIES.

FUND
 HIGHLIGHTS

-    Interest rates for Treasuries rose in general during this period. The
     exception was the 30-year Treasury sector, which experienced a decline of
     approximately 20 basis points in yield due to supply reduction.

-    We responded by reducing the overall interest-rate risk of the portfolio.
     The Fund also benefited from its exposure to the 30-year Treasury sector.

-    The incremental income paid by the Fund's mortgage-backed securities offset
     their declining prices.

of 5.4% in the first quarter of 2000. In the first quarter of 2000, the closely
watched Employment Cost Index jumped 1.4%. Until we see a cooling in the
economy, we believe that the Federal Reserve will continue raising short-term
rates in an attempt to get out in front of inflation. We concur with the general
perception that the Fed will raise rates by another 50 to 75 basis points over
the next six months. Accordingly, we will continue to position the Fund
defensively in terms of interest-rate risk.

We believe the Fund's non-Treasury holdings currently offer compelling income
opportunities. Ten-year government agency securities offer yields in the 7.25%
area, while agency mortgage-backed securities yield approximately 8.00%. We
believe these to be quite attractive from a longer-term perspective.

proud to help you pursue your investment income goals.

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

MARKET
 HIGHLIGHTS

-    Continued strong GDP growth, combined with some negative consumer price
     news, has prompted the Federal Reserve Board to continue raising the
     federal funds rate.

-    Bolstered by the recent budget surplus, the U.S. Treasury announced it
     would buy back large amounts of previously issued long-term Treasury debt.

-    This combination of the Federal Reserve pushing short-term rates higher,
     and Treasury buyback demand driving long-term rates lower, caused an
     inversion of the yield curve. At the end of the period, two-year Treasuries
     yielded almost 0.75% more than 30-year Treasuries.

The prices of short-maturity bonds are directly influenced by changes in
monetary policy. During the past six months, the Federal Reserve Board has
become more aggressive in its efforts to restrain the economy. We believe the
Fed will continue to increase short-term interest rates until consumption slows
and inflationary pressures in the labor market subside. This means the fed funds
rate will likely increase an additional 50 to 75 basis points over the next six
months.

The corporate and mortgage bond sectors often underperform the Treasury market
during periods of monetary tightening. Although these sectors have lagged
government securities in the past several months, in this case most of the
underperformance has been concentrated in longer-maturity bonds where the
Treasury's announced buyback of long-term government debt has caused investors
to reevaluate their long-maturity corporate holdings.

Relative underperformance in the corporate sector has been greater than in the
mortgage sector. Investors are beginning to question the sustainability of both
the economic expansion and growth in corporate earnings as the Fed continues to
raise interest rates. Avoiding problem credits and industries throughout the
period was a meaningful contributor to the Fund's performance as the benchmark
indices contain a measure of both. Diligent credit research is now more
important than ever in the corporate sector.

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

BY EMPHASIZING CORPORATE AND MORTGAGE SECURITIES, WE BOOSTED THE FUND'S INCOME
LEVEL, WHILE EXCELLENT RESEARCH IN THE CORPORATE AND MORTGAGE MARKET ALLOWED US
TO IDENTIFY SECURITIES THAT PERFORMED BETTER THAN THEIR MARKET AVERAGES.

FUND
 HIGHLIGHTS

-    The Federal Reserve Board increased the federal funds rate by 75 basis
     points over the past six months. This caused the yields on two-year
     Treasury notes to rise to 6.68%, an increase of almost 90 basis points. To
     contend with this environment, we shortened the portfolio's duration
     slightly.

-    The Fund maintained a significant overweighting in the corporate and
     mortgage sectors in order to provide a higher level of income.

Several strategic decisions contributed to the Fund's strong performance
relative to its benchmark. We reduced our duration in order to reduce the impact
of rising short-term interest rates on the Fund's share price. By emphasizing
corporate and mortgage securities, we boosted the Fund's income level, while
excellent research in the corporate and mortgage market allowed us to identify
securities that performed better than their market averages. Our mortgage
holdings were concentrated in the asset-backed and commercial mortgage-backed
areas. Within the corporate portfolio, we upgraded the quality of the portfolio
to include such companies as Ford and General Electric.

Short-maturity corporate and mortgage yields are higher today than in recent
years. These high yields should provide adequate protection against further
increases in short-term interest rates. We would expect to increase our
interest-rate sensitivity later in the year once it becomes clear that the Fed
has completed its monetary tightening.

Thank you for your continued investment in the Strong Short-Term Bond Fund. We
appreciate the opportunity to help you pursue your important financial goals.

MARKET
 HIGHLIGHTS

-    A convergence of robust economic growth, tight labor markets, and rising
     commodity prices contributed to the Federal Reserve's decision to raise
     rates during the period. Short-term bond yields are more sensitive to
     changes in Fed policy than those of longer-maturity bonds.

-    The U.S. Treasury announced a plan to repurchase $30 billion of
     long-maturity government bonds.

-    This combination of events caused two-year yields to rise almost 90 basis
     points even as 30-year government yields declined by 20 basis points. The
     yield curve is now inverted by approximately 70 basis points.

High-yield bonds suffered through lackluster performance over the past six
months, as the twin problems of rising interest rates and larger credit-risk
premiums took a bite out of returns. The Federal Reserve's efforts to combat
inflation remained front and center on the minds of market participants.

The rise in Treasury rates was not nearly as dramatic as the rise in credit-risk
premiums, however. The yield on the Lehman Brothers High-Yield Bond Index rose
to 12.72% from 11.19% during the six-month period. The rise in Treasury yields
was responsible for 0.19% of the index's yield increase, while 1.34% of the
increase was tied to a rise in credit-risk premiums--the yield in excess of
Treasury yields paid to high-yield bond investors as compensation for taking on
credit risk. Although the Federal Reserve is poised to continue raising
short-term interest rates, it appears to us that credit-risk premiums are at or
near their peaks for this cycle. We believe that, as a result, high-yield bonds
represent very good values at this time.

The market environment over the past 18 months has been characterized by a
generally conservative approach to financing new issues. Terms are very
attractive (with high yields and well-structured deals), and credit quality is
generally strong. Over the past six months, media and telecom companies have
represented a disproportionate share of the new-issue calendar. These have been
among the best-performing sectors of the market over the past two years, and
investors continue to favor these issues over those from other sectors. This

combination of attractive terms and good credit quality bode well for the
near-term health of the overall market.

We have geared our credit research toward finding companies that generate strong
free cash flow growth or that benefit from strong and growing asset value. We
also look for companies in industries that we expect to perform well in the
future and provide fertile ground for investment opportunities. We believe the
combination of good industry conditions and strong companies should result in a
good investment climate for the Fund in the near term.

Over the next six months, we expect the Federal Reserve to continue raising
interest rates in an effort to cool the economy from its blistering pace to a
more moderate and sustainable rate of growth going forward. High-yield bonds
offer attractive value and should benefit as investors begin to embrace this
outlook.

Thank you for investing in the Strong High-Yield Bond Fund. We value the trust
you have placed in us.

MARKET
 HIGHLIGHTS

-    The Federal Reserve raised interest rates three times during the period,
     taking the federal funds rate to 6.00% from 5.25%. Longer-term interest
     rates rose, as well, with the ten-year Treasury moving to 6.21% from 6.05%.

-    Yield premiums on high-yield bonds rose during the period, as the spread
     between the Lehman Brothers High-Yield Bond Index and ten-year Treasuries
     widened to 6.51% from 5.17%. This left the yield on the index at 12.72%.

-    New bond issuance was reduced dramatically from the same period one year
     earlier and was dominated by media and telecom companies.

The combination of rising interest rates and widening credit-risk premiums cut
into the performance of high-yield bonds over the past six months. The Federal
Reserve continued to play a leading role, raising the federal funds rate by 75
basis points over the period. This continued effort to stave off inflation had
an impact on three-year and ten-year Treasury rates, as well.

Dwarfing the rise in Treasury yields, however, was the rise in credit-risk
premiums. The yield on the Lehman Brothers High-Yield Bond Index rose to 12.72%
from 11.19% over the six months--but just 19 basis points of that rise was
attributable to interest-rate hikes. The remainder reflected an increase in risk
premiums--the additional yield investors demand to compensate for the higher
risk associated with high-yield bonds. The Federal Reserve has continued to
raise short-term interest rates, but we believe the rise in risk premiums is at
or near an end for this cycle. This means that high-yield bonds currently
reflect attractive values.

One of the barometers that we use to judge the appetite for risk in the
high-yield marketplace is the new issue calendar. By carefully studying new
issues that come to market, we can learn a great deal about the market's stance
toward credit risk. Over the past 18 months, for example, the market environment
has been conservative, with high yields paid, well-structured deals, and
generally strong credit quality. This combination bodes well for the market's
overall near-term health.

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

 ... THE MARKET ENVIRONMENT HAS BEEN CONSERVATIVE, WITH HIGH YIELDS PAID,
WELL-STRUCTURED DEALS, AND GENERALLY STRONG CREDIT QUALITY. THIS COMBINATION
BODES WELL FOR THE MARKET'S OVERALL NEAR-TERM HEALTH.

FUND
 HIGHLIGHTS

-    We focus on finding investments with attractive income potential and low
     volatility relative to the high-yield market as a whole. To this end, we
     emphasize high-coupon, callable bonds and shorter-maturity issues.

-    Our average credit quality is BB, which represents the highest-rated sector
     of the high-yield market.

-    Media and telecommunications are key sectors for the Fund. Many of the
     companies in these industries are poised to refinance bonds that were
     issued three to five years ago.

We continue to find attractive investments for the Fund. There are many
high-coupon callable bonds nearing their call dates as a result of heavy
issuance activity three to five years ago, especially in the media and
telecommunications sectors. An example would be Qwest Communications, with a
10 7/8% coupon and due 4/1/07. These bonds were issued in 1997, when Qwest
was a single-B-rated company. Qwest has since been upgraded, and is now rated
BB. These bonds first become callable on 4/1/02, and Qwest is likely to
refinance them at a lower rate.

Over the next six months, we expect the Federal Reserve to continue raising
interest rates in its ongoing effort to cool the economy. We expect the economy
to slow to a more moderate and sustainable rate of growth. Our portfolio, which
is designed to offer a low degree of volatility, is positioned well for the
environment we foresee.

Thank you for your investment in the Strong Short-Term High Yield Bond
Fund.

BOND GLOSSARY


BOND QUALITY RATINGS--There are services that analyze the financial condition of
a bond's issuer and then assign it a rating. The best-known rating agencies are
Standard and Poors and Moody's. The highest-quality bonds are rated AAA (S&P) or
Aaa (Moody's). The scale descends to AA, A, then BBB, and so on, down to D.
Bonds with a rating of BBB or higher are considered investment-grade. Bonds
rated BB and below are considered "junk bonds." Typically, the lower a bond's
rating, the higher yield it must pay in order to compensate the bondholder for
the added risk.

MATURITY--Like a loan, a bond must be paid off on a certain date. A bond's
maturity is the time remaining until it is paid off. Bonds typically mature in a
range from overnight to 30 years from now. Typically, bonds with longer
maturities will have higher yields and larger price changes in reaction to
interest-rate changes. In rare situations, shorter-term bonds will have higher
yields; this is known as an inverted yield curve (see definition that follows).

DURATION--Duration is similar to maturity, but also accounts for the semi-annual
interest payments made by most bonds. Duration is a useful tool for determining
a bond or a bond fund's sensitivity to interest-rate changes. The higher the
duration, the more a bond's price will fluctuate when interest rates change.

TREASURY SPREAD--The Treasury spread is the difference in yield between a
Treasury bond (issued by the federal government) and a bond with an equal
maturity, but from another category, such as a corporate bond. This calculation
is used to measure the prices of corporate bonds, mortgage-backed securities,
and other non-government issues relative to Treasuries. Higher spreads occur in
uncertain times when investors buy Treasuries for their safety and sell other
types of bonds.

YIELD--Yield is the income your investment is generating. It is calculated by
taking the income paid by a bond in a given period of time, often 30 days,
annualizing it, and stating it as a percentage of the money invested.

YIELD CURVE--The yield curve is a graph that plots the yields of Treasury bonds
against their maturities. Under normal circumstances, this line will slope
upward, reflecting longer-maturity bonds having higher yields. In rare
circumstances, such as in a time of deflation, the yield curve may slope
downward, or "invert." The steepness of the yield curve shifts depending on
economic trends and outlooks. Properly positioned, a bond investor can profit
from these shifts.

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

1.  Organization

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

    - Strong Bond Fund (a series of Strong Income Funds II, Inc.(1)) (formerly
      known as Strong Institutional Bond Fund, a series of Strong Institutional
      Funds, Inc.)
    - Strong Corporate Bond Fund, Inc.(1)
    - Strong Government Securities Fund, Inc.(1)
    - Strong Short-Term Bond Fund, Inc.(1)
    - Strong High-Yield Bond Fund (a series of Strong Income Funds, Inc.(1))
    - Strong Short-Term High Yield Bond Fund (a series of Strong Income Funds,
      Inc.(1))

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

    During 1999, the Board of Directors of the Strong Bond Fund approved
    changing the Fund's fiscal year-end from February 28th to October 31st.

    Effective September 1, 1999, the Strong Bond Fund, Strong Corporate Bond
    Fund, Strong Government Securities Fund and Strong Short-Term Bond Fund have
    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.

    Effective March 1, 2000, the Strong High-Yield Bond Fund and Strong
    Short-Term High Yield Bond Fund issued two classes of shares: Investor 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 cost and fair value of these restricted
         securities held at April 30, 2000 were as follows:

</TABLE>

         *Percentage of restricted securities which are either Section 4(2)
         commercial paper or are eligible for resale pursuant to Rule 144A under
         the Securities Act of 1933 and also have been determined to be liquid
         by the Advisor based upon guidelines established by the Funds' Board of
         Directors.

    (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.

<PAGE>

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

         Net investment income and 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 monthly
         and distributes any net capital gains that it realizes annually.
         Dividends are declared on each day that the net asset value is
         calculated, except for bank holidays.

    (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
         Fund's investment objectives and limitations. The Funds intend to use
         such derivative instruments primarily to hedge or protect from adverse
         movements 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 options 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.

    (G)  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.


                                                                              37

3.  Related Party Transactions

    The Advisor, with whom certain officers and directors of the Funds are
    affiliated, provides investment advisory, administrative, shareholder

    *The Strong High-Yield Bond Fund and the Strong Short-Term High Yield Bond
     Fund do not offer Institutional Class shares.
    **Effective March 1, 2000.

    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, except where indicated. 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 Funds 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. 12b-1 fees (over
    $1,000) incurred by the Funds are reported in the Funds' Statements of
    Operations. During the period November 1, 1999 to April 30, 2000, 12b-1 fees
    (under $1,000) incurred by Strong Bond Fund, Strong Government Securities
    Fund, Strong Short-Term Bond Fund, Strong High-Yield Bond Fund and Strong
    Short-Term High Yield Bond Fund were $11, $42, $11, $6 and $6, 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 agreements with the money market funds.

    Certain information regarding related party transactions, excluding the
    effect of waivers and absorptions, for the six months ended April 30, 2000

6.  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 Fund's 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 April 30, 2000, there were no borrowings by
    the Funds under the LOC.

7.  Income Tax Information

    The investment cost, gross unrealized appreciation and depreciation on
    investments and capital loss carryovers (expiring in varying amounts through
    2007) for federal income tax purposes were as follows:
