EIGHT BASIC PRINCIPLES FOR SUCCESSFUL MUTUAL FUND INVESTING

These  common-sense rules are followed by many successful  investors.  They make
sense for beginners,  too. If you have a question on these principles,  or would
like to discuss them with us, please contact us at 1-800-368-3863. We're here 24
hours a day, seven days a week to take your call.

- ---------------------------------------1----------------------------------------
                                  HAVE A PLAN.

[PICTURE OF FOLDER LABELED INVESTMENTS]
Even a simple plan can help you take control of your  financial  future.  Review
your plan once a year, or if your circumstances change.

- ---------------------------------------2----------------------------------------
                      START INVESTING AS SOON AS POSSIBLE.

[PICTURE OF CLOCK]
Make time a valuable  ally. Let it put the power of compounding to work for you,
while helping to reduce your potential investment risk.

- ---------------------------------------3----------------------------------------
                           DIVERSIFY YOUR PORTFOLIO.

[PICTURE OF PIE CHART OF ASSET DIVERSIFICATION]
By investing in different  asset  classes - stocks,  bonds,  and cash - you help
protect  against poor  performance  in one type of  investment  while  including
investments most likely to help you achieve your important goals.

- ---------------------------------------4----------------------------------------
                               INVEST REGULARLY.

[PICTURE OF MEMO REMINDER TO INVEST]
Investing is a process,  not a one-time event.  By investing  regularly over the
long term, you reduce the impact of short-term market gyrations,  and you attend
to your long-term plan before you're tempted to spend those assets on short-term
needs.

- ---------------------------------------5----------------------------------------
                       MAINTAIN A LONG-TERM PERSPECTIVE.

[PICTURE OF GRAPH SLOPING UPWARD]
For  most  individuals,  the best  discipline  is  staying  invested  as  market
conditions change. Reactive,  emotional investment decisions are all too often a
source of regret - and of principal loss.

- ---------------------------------------6----------------------------------------
             CONSIDER STOCKS TO HELP ACHIEVE MAJOR LONG-TERM GOALS.

[PICTURE OF PIE CHART OF ASSET DIVERSIFICATION EMPHASIZING STOCKS]
Over time,  stocks have  provided the more powerful  returns  needed to help the
value of your investments stay well ahead of inflation.

- ---------------------------------------7----------------------------------------
              KEEP A COMFORTABLE AMOUNT OF CASH IN YOUR PORTFOLIO.

[PICTURE OF DOLLAR SIGN]
To meet current needs, including emergencies, use a money market fund or a bank
account - not your long-term investment assets.

- ---------------------------------------8----------------------------------------
                            KNOW WHAT YOU'RE BUYING.

[PICTURE OF MAGNIFYING GLASS]
Make sure you understand the potential risks and rewards associated with each of
your investments.  Ask questions...request  information...make up your own mind.
And choose a fund company that helps you make informed investment decisions.

THE STRONG SHORT-TERM BOND FUND


OVER  THE  PAST  SIX  MONTHS,   WE  HAVE  MAINTAINED  OUR  CAREFUL  APPROACH  TO
FIXED-INCOME INVESTING.

The Strong Short-Term Bond Fund seeks total return by investing for a high level
of current income with a low degree of share-price fluctuation. The Fund invests
primarily in short- and  intermediate-term,  investment-grade  debt obligations,
and its average portfolio maturity will normally be between one and three years.

For the six months ended April 30, the Fund's total return stood at 3.68%,  well
ahead of our benchmarks and our peer group average: The Lehman Brothers 1-3 Year
Government/Corporate  Bond Index  returned  2.26% for the same  period,  and the
Lipper Short Investment Grade Debt Funds Index returned 2.27%.*(1)

THE PAST SIX MONTHS
The first six months of the Fund's  fiscal  year can really be divided  into two
periods.  First,  in November  and  December  1996,  the bond market  rallied as
investors expected the economy to slow in the first quarter of 1997. However, by
early 1997, the market  recognized that the economy was stronger than previously
forecast. Furthermore, it became apparent that the Federal Reserve would need to
raise  short-term  interest rates to slow economic growth and head off potential
increases in inflation.

Rates rose significantly  after Federal Reserve Chairman Alan Greenspan gave his
Humphrey-Hawkins  testimony to Congress in February.  In his remarks,  Greenspan
gave a strong signal that the Fed would raise the fed funds rate in March--as it
in fact did.  Yields on two-year notes increased by more than 50 basis points to
6.27% over the six months through April,  while 30-year bond yields rose by more
than 30 basis points to 6.96%.

Although  interest  rates at the end of April were higher than in November,  the
market had stabilized within a month of the Fed's hike. Most investors  appeared
to  believe  that the  increase  in  short-term  interest  rates  needed to slow
economic growth would be relatively small and short-lived.

OUR STRATEGY REMAINS INTACT
In this  environment  over the past six months,  we have  maintained our careful
approach to  fixed-income  investing.  We believe that  successful  fixed-income
management begins with a top-down  analysis of the economy,  interest rates, and
the supply of and demand for credit--and ends with extensive  security analysis.
We  also  believe  that  defining  benchmarks  and  then  making  only  moderate
deviations is an efficient way to help manage risk.

We have kept the Fund's interest-rate exposure slightly shorter than normal as a
mild defensive measure against rising interest rates. The Fund's duration
currently stands at 1.7 years.

We also have kept a good portion of the portfolio in  floating-rate  securities.
As  interest  rates move up, the level of income  these  bonds pay out resets at
higher levels. We intend to maintain this position for the foreseeable future.


ADDING INTERNATIONAL OPPORTUNITIES
In March,  Shirish  Malekar joined the management of the Strong  Short-Term Bond
Fund. We believe that, over time, international  diversification can help reduce
total  portfolio  risk and  increase  return  potential.  With his nine years of
investment experience--including his management of the Strong International Bond
Fund and the Strong Short-Term Global Bond Fund (both since March 1994)--Shirish
will apply  top-down  analysis  and  individual  security  research  to identify
attractive  international  issues for the Fund.  To help  contain  the risk that
currency  fluctuation  can pose, he will actively  hedge  non-dollar-denominated
investments.  We anticipate that such  investments will take up about 10% of the
portfolio,  even  though  the  Fund's  prospectus  allows it to put up to 25% of
assets in such securities.

<PAGE>

OUTLOOK
As of the end of April, bond market sentiment  appeared to hold that the Federal
Reserve will only need to make modest  adjustments to interest rates in order to
achieve a slowdown in economic  growth.  We believe  there is still some risk of
higher interest rates, though; the economy has continued its strong momentum and
the market  for labor is still  tight,  driving  increases  in wages.  The small
increase  in  interest  rates in March is  unlikely  to be  enough  to slow this
economy in a  meaningful  way.  Therefore,  we intend to keep our  interest-rate
positioning somewhat shorter than usual.

That we have adopted a moderately  defensive approach toward interest rates does
not mean that we are pessimistic  about bonds'  prospects.  To the contrary,  we
believe bonds  represent a very good value to investors.  They are  particularly
valuable as a way to moderate risk in more aggressive portfolios.

We appreciate  your  investment in the Strong  Short-Term Bond Fund, and will do
our best to earn your continued confidence.


Sincerely,

WITHOUT EXCESS VOLATILITY, ATTENTION TO VALUATIONS IS ESSENTIAL.

The Strong Government Securities Fund seeks total return by investing for a high

Fund  normally  invests  at least  80% of its total  assets  in U.S.  government
securities.(1)

For the six months ended April 30, the Fund's total return stood at 2.29%,  well
ahead of our benchmark  and the average for our peer group of funds.  The Lipper

the supply of and demand for credit--and ends with extensive  security analysis.
We  also  believe  that  defining  benchmarks  and  then  making  only  moderate
deviations is an efficient way to help manage risk.

We seek to add value to the  portfolio in many  different  ways. To this end, we
shortened  the Fund's  duration  in February  to help limit its  sensitivity  to
interest-rate increases. The Fund's duration currently stands at 4.3, toward the
short end of our typical range.  We also positioned the Fund for a flattening of
the yield  curve--that is, a situation  that can cause longer-maturity  bonds to
outperform  shorter-maturity  issues.  This  strategy paid off, as 30-year bonds
proceeded to outperform two-year notes.  Finally, we have moderately reduced our
exposure to  mortgage  securities.  We made this last move  because we believe a
good  part  of that  market  is now  fully  valued,  making  it  harder  to find
opportunities at reasonable prices.  Because we strive with this Fund to provide
consistently above-average returns without excess volatility,  this attention to
valuations is essential.

A NEW COMANAGER
In March, John Bender became comanager of the Strong Government Securities Fund.
We're confident that John's eight years of investment experience--including time
as an analyst and as comanager of the Strong Corporate Bond Fund--will add value
to the management of this Fund.


OUTLOOK
As of the end of April, bond market sentiment  appeared to hold that the Federal
Reserve will only need to make modest  adjustments to interest rates in order to
achieve a slowdown in economic  growth.  We believe  there is still some risk of
higher interest rates, though; the economy has continued its strong momentum and
the  market for labor  remains  tight,  driving  increases  in wages.  The small
increase  in  interest  rates in March is  unlikely  to be  enough  to slow this
economy in a  meaningful  way.  Therefore,  we intend to keep our  interest-rate
positioning somewhat shorter than usual.

We appreciate your investment in the Strong Government  Securities Fund. We look
forward to earning your continued confidence.


Sincerely,

THE STRONG CORPORATE BOND FUND

OUR MOST SIGNIFICANT CHANGE IN SECTOR ALLOCATION OVER THE PAST SIX MONTHS WAS AN
INCREASE IN OUR EXPOSURE TO THE BANKING INDUSTRY.

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 investment-grade corporate debt obligations.

For the six months ended April 30, the Fund's total return stood at 3.22%,  well
ahead of our benchmarks and our peer group:  The Lehman  Brothers  Corporate BAA
Bond Index  returned  1.63% for the same period,  and the Lipper  Corporate Debt
Funds BBB Rated Index returned 1.87%.*(1)

============================================

THE PAST SIX MONTHS
The first six months of the Fund's  fiscal  year can really be divided  into two
periods.  First,  in November  and  December  1996,  the bond market  rallied as
investors expected the economy to slow in the first quarter of 1997. However, by
early 1997, the market  recognized that the economy was stronger than previously
forecasted.  Furthermore, it became apparent that the Federal Reserve would need
to  raise  short-term  interest  rates  to slow  economic  growth  and  head off
potential increases in inflation.

Rates rose significantly  after Federal Reserve Chairman Alan Greenspan gave his
Humphrey-Hawkins  testimony to Congress in February.  In his remarks,  Greenspan
gave a strong signal that the Fed would raise the fed funds rate in March--as it
in fact did late that month.  Yields on two-year notes increased by more than 50
basis  points to 6.27%,  while  30-year  bond  yields rose by more than 30 basis
points to 6.96% at the end of April.

Although  interest  rates at the end of April were higher than in November,  the
market had stabilized within a month of the Fed's hike. Most investors  appeared
to  believe  that the  increase  in  short-term  interest  rates  needed to slow
economic growth would be relatively small and short-lived.

OUR STRATEGY REMAINS INTACT
In this  environment  over the past six months,  we have  maintained our careful
approach to fixed-income  investing. As we manage the portfolio, we consider the
average maturity, sector weightings, and other characteristics of our benchmark,
the Lehman Brothers  Corporate BAA Bond Index. We deviate from this index to the
extent that our research indicates is appropriate.

We seek to add value to the  portfolio in many  different  ways. To this end, we
shortened  the Fund's  duration  in February  to help limit its  sensitivity  to
interest-rate  increases.  We also  positioned  the Fund for a flattening of the
yield  curve--that  is, a  situation  that can  cause  longer-maturity  bonds to
outperform  shorter-maturity  issues.  This  strategy paid off, as 30-year bonds
proceeded to outperform  two-year  notes.  Finally,  we have  continued to boost
returns   through  careful  issue  selection  and  sector  rotation  within  the
corporate-bond market.

Our most significant change in sector allocation over the past six months was an
increase in our  exposure to the banking  industry.  We believe  that  continued
consolidation in this  sector--particularly  in regional  banking--is  likely to
allow for many  improvements in these issues'  ratings,  with  subsequent  price
appreciation.

OUTLOOK
As of the end of April, bond market sentiment  appeared to hold that the Federal
Reserve will only need to make modest  adjustments to interest rates in order to
achieve a slowdown in economic  growth.  We believe  there is still some risk of
higher interest rates, though; the economy has continued its strong momentum and
the market  for labor is still  tight,  driving  increases  in wages.  The small
increase  in  interest  rates in March is  unlikely  to be  enough  to slow this
economy in a  meaningful  way.  Therefore,  we intend to keep our  interest-rate
positioning somewhat shorter than usual. However, with continued strong economic
fundamentals and corporate  earnings,  we expect to find good  opportunities for
outperformance  in  both  the  investment-grade  and  high-yield  markets  going
forward.

Thank you for your investment in the Strong Corporate Bond Fund. We look forward
to serving your investment needs in the future.

NAVIGATING A TRICKY MARKET
Although we enjoyed  success,  the market  presented  us with  challenges.  From
November through most of March, the market overall had a fairly complacent tone.
It may have been too  complacent,  particularly  with regard to securities  from
less-established companies--ones where significant improvements lie four to five
years away.

These  lower-quality  issues became overpriced,  and subsequently were among the
hardest hit in late March and in April,  when a correction  hit the market.  The
catalyst for the downturn was the Federal  Reserve's  raising of interest rates,
even though  high-yield  bonds tend to be less  sensitive to changes in interest
rates than investment-quality issues.

Some changes we had made to the portfolio  helped us to weather the  correction.
We had worked to raise the Fund's credit profile,  building BB issues to about a
third of the portfolio. That raised the Fund's average credit quality to BB from
B six months  earlier--still in line with our benchmark,  but a boost given that
lower-quality  issues suffered the most when the market turned down. We had also
pulled the Fund's duration in to about 90% of our benchmark's,  which translates
into a figure of 4.0. That  decreased  sensitivity  to  interest-rate  hikes was
beneficial as rates moved up.

============================================

WHERE WE ARE NOW
That  difficult  three weeks  served as a wakeup call for the market,  restoring
some rationality. It left in its wake some unpleasantness,  but some opportunity
as well.

The difference--or  spread--between  the yields of high-yield bonds and those of
high-quality  issues such as  Treasuries  has since  returned to a fairly narrow
band.  Investors  are  confident  in  companies'  ability to pay off their debt,
stimulating  demand for high-yield  issues and thus driving their prices higher.
We anticipate  that those spreads will remain tight over the next several months
or longer, as investors remain optimistic.

We believe that optimism is justified, given strong reports on the first-quarter
GDP  growth  rate and the  number of  companies  posting  earnings  in excess of
analysts' estimates.  Reports of that growth slowing somewhat are also positive,
as they mark a retreat to levels that are sustainable over the longer term.

Sectors we're  favoring at the moment  include  airlines,  led by top holding US
Airways.  We like this  company for its healthy  level of cash and  unencumbered
assets,  and its dedication to controlling labor costs and cutting  unprofitable
routes. We also like larger, broad line financial institutions, which seem to be
insulated from the troubles hurting some more narrowly focused financial firms.

We're  underweighting  oil and gas  issues.  These  were  overpriced  before the
correction,  and now appear to be just fairly priced.  Because we generally look
for issues that are selling  cheaply  relative to their potential  return,  they
still don't appeal to us at their current prices.

<PAGE>

OUTLOOK
We  anticipate  that  fundamental  conditions  will remain very positive for the
balance  of the year.  That  said,  we will  still be  grappling  with the tight
spreads between  Treasury-bond yields and those on lower-quality  issues, and it
seems  entirely  plausible  that the Fed will raise interest rates at least once
more in the coming months.  That's one reason we expect more  volatility in this
area than we saw for most of the past year.

Even under smooth  conditions,  though,  the high-yield  bond market is one that
demands  a certain  patience  from its  investors.  Because  this  Fund  invests
primarily in  non-investment  grade bonds (sometimes  called junk bonds),  it is
subject to greater share-price  volatility than a fund that invests primarily in
investment-grade  bonds. That's why we strongly recommend that investors in this
Fund maintain a long-term time horizon. Even when short-term volatility does hit
the market, the income stream this Fund provides can serve as a healthy cushion.

The Fund's increased quality and shortened  duration should help it contend with
shorter-term  ups and downs.  We may even raise the  portfolio's  credit quality
further,  favoring  BB issues over Bs.  Were the  economy's  growth rate to slow
somewhat, triggering a sustained rally in Treasury bonds, it's possible we could
make  such a move  while  maintaining  the  level of  income  that  this Fund is
designed to provide.

We thank you for your  investment  in the Strong  High-Yield  Bond Fund. We look
forward to continuing to serve your investment needs.


Sincerely,

*    The Lehman  Brothers  High-Yield Bond Index is an unmanaged index generally
     representative of the performance of corporate bonds rated below investment
     grade.  The Lipper High  Current  Yield Funds Index is an  equally-weighted
     performance index of the largest  qualifying funds in this Lipper category.
     Source of the Lehman  index data is  Micropal.  Source of the Lipper  index
     data is Lipper Analytical Services, Inc.

1    Average annual total return and total return measure change in the value of
     an  investment  in the Fund,  assuming  reinvestment  of all  dividends and
     capital gains.  Average  annual total return  reflects  annualized  change,
     while total return reflects aggregate change.

2    The  Advisor  temporarily  waived fees of 0.110% and  absorbed  expenses of
     0.135%.  Otherwise,  current  yield would have been 9.12% and returns would
     have been lower.  Yields are historical and do not represent future yields,
     which will fluctuate.

3    The Fund's average maturity includes the effect of futures.

4    For purposes of this average rating, the Fund's short-term debt obligations
     have been assigned a long-term rating by the Advisor.

NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------
April 30, 1997 (Unaudited)

1.   ORGANIZATION
     The Strong  Income  Funds  consist of Strong  Short-Term  Bond Fund,  Inc.,
     Strong Government  Securities Fund, Inc., Strong Corporate Bond Fund, Inc.,
     and Strong  High-Yield  Bond Fund (a series of Strong Income Funds,  Inc.).
     The  Funds  are  diversified,   open-end  management  investment  companies
     registered under the Investment Company Act of 1940. The inception date for
     the Strong High-Yield Bond Fund was December 28, 1995.

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  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 current 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,  1997 were as  follows  (in
          thousands):

          * Of these  securities,  which are restricted  from resale,  70.1% are
          eligible for resale  pursuant to Rule 144A under the Securities Act of

          upon guidelines established by the Fund's Board of Directors.

          ** Of these  securities,  which are restricted from resale,  88.1% are

          upon guidelines established by the Fund's Board of Directors.

          *** Of these securities,  which are restricted from resale,  86.0% 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 Fund's Board of Directors.

          **** Of these securities,  which are restricted from resale, 89.7% 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 Fund's Board of Directors.

     (B)  Federal Income and Excise Taxes and  Distributions  to Shareholders --
          It is the  Funds'  policy  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.

          The  character  of  distributions   made  during  the  year  from  net
          investment   income  or  net  realized   gains  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.

     (C)  Realized  Gains and  Losses  on  Investment  Transactions  -- 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)  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.  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.

     (E)  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.
          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.

- --------------------------------------------------------------------------------
     (F)  Foreign Currency Translation -- Investment securities and other assets
          and  liabilities   initially   expressed  in  foreign  currencies  are
          converted 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.

     (G)  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.

     (H)  Additional  Investment Risk -- The use of futures contracts,  options,
          foreign  denominated  assets and  forward  foreign  currency  exchange
          contracts  for  purposes of hedging the Funds'  investment  portfolios
          involves, to varying degrees, elements of market risk in excess of the
          amount  recognized  in the  statement of assets and  liabilities.  The
          predominant  risk with futures  contracts is an imperfect  correlation
          between  the value of the  contracts  and the  underlying  securities.
          Foreign  denominated  assets and  forward  foreign  currency  exchange
          contracts  may  involve  greater  risks  than  domestic  transactions,
          including  currency,  political  and economic,  regulatory  and market
          risks.

     (I)  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 of assets and liabilities and disclosure of contingent  assets
          and  liabilities  at the  date of the  financial  statements,  and the
          reported  amounts  of  increases  and  decreases  in net  assets  from
          operations  during the reporting  period.  Actual results could differ
          from those estimates.

     (J)  Other -- Investment security transactions are recorded as of the trade
          date.  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.

5.   RELATED PARTY TRANSACTIONS
     Strong Capital Management, Inc. (the "Advisor"), with whom certain officers
     and directors of the Funds are  affiliated,  provides  investment  advisory
     services and shareholder  recordkeeping  and related services to the Funds.
     Investment  advisory fees,  which are  established by terms of the Advisory
     Agreements,  are based on the  following  annualized  rates of the  average
     daily net assets: Strong Government Securities Fund .60%, Strong Short-Term
     Bond  Fund,  Strong  Corporate  Bond Fund and Strong  High-Yield  Bond Fund
     .625%.  Advisory  fees are subject to  reimbursement  by the Advisor if the
     Funds' operating expenses exceed certain levels.  Shareholder recordkeeping
     and related service fees are based on contractually  established  rates for
     each open and closed  shareholder  account.  In  addition,  the  Advisor is
     compensated  for  certain  other  services  related to costs  incurred  for
     reports to shareholders.

     The Funds may invest cash  reserves in money  market  funds  sponsored  and
     managed by Strong Capital Management, Inc., 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, the
     Advisor  remits to each Fund an amount equal to all fees  otherwise  due to
     them under their investment  advisory  agreement for the assets invested in
     such money market funds.

     Certain  information  regarding related party  transactions,  excluding the
     effects of waivers and  reimbursements,  for the six months ended April 30,
