PRESIDENT'S LETTER
AUGUST 15, 1997


To Our Shareholders:

The first six months of 1997 have been a  roller-coaster  ride for fixed  income
investors. At the beginning of the year the bellwether thirty-year Treasury bond
yielded  6.64%.  By late April the yield had risen to 7.14%  before it began its
descent to 6.78% at the end of June. As you know,  bond prices move inversely to
yields,  staging a "mirror"  roller  coaster  ride  which  produced a 2.3% total
return on the long Treasury bond for the period.

THE INFLATION STORY IN 1997

Contrary to what this volatility  might indicate,  the compelling  story for the
six-month period was the absence of  reacceleration of inflation  pressures.  In
fact,  evidence  suggests  that  inflation is actually  declining.  This is true
particularly  when one  takes  into  account  the  overstatement  of  structural
inflation  revealed by the Boskin report,  the study  commissioned by the Senate
Finance  Committee to review the  calculation of the Consumer Price Index (CPI).
This report found that the CPI probably overstates true increases in the cost of
living by approximately 1.1% per year.

This  leaves  us with the  understanding  that real  interest  rates on the long
Treasury  bond are 300 to 400 basis points  higher than might be expected  given
today's actual  annualized  inflation  rate of around 2%. We therefore  conclude
that there is  opportunity  for further  declines in long-term  rates with their
commensurate increase in bond prices as we move through the second half of 1997.

CAN THE GOOD NEWS CONTINUE?

The good news on the inflation front should continue to be a positive  influence
on fixed  income  markets  for some time as the  economy  continues  to slow its
growth rate from the torrid pace of 1997's first quarter. We believe that due to
the  continuation of  productivity  improvements  in U.S.  businesses,  economic
growth rates of around 3% may be sustainable without reigniting inflation.  This
is in  contrast  to the 2% to 2.5% rates of growth  that have been  historically
viewed by the Federal  Reserve  Board as a "speed  bump."  Therefore,  for fixed
income investors the climate should remain favorable for returns of at least the
portfolio coupon rate, with the possibility of some capital appreciation if long
term  interest  rates  decline as we believe they will,  in  recognition  of the
pattern of slowing global inflation pressures.

As always,  we appreciate your  continuing  investment in the Security Funds. We
invite your questions and comments at any time.

MANAGER'S COMMENTARY
AUGUST 15, 1997


SECURITY INCOME FUND
CORPORATE BOND SERIES

Volatility  was the key word for fixed income market  behavior in the first half
of 1997.  The  thirty-year  Treasury  bond  began  the year  yielding  6.64% and
finished  June at  6.78%.  In the  intervening  months it rose as high as 7.14%,
managing to gain only 2.3% in total return over the six months. Corporate issues
fared  slightly  better,  as the Lehman  Corporate  Bond Index rose  3.07%.  The
Corporate Bond Series of Security  Income Fund generated a positive total return
for the six-month  period of 2.35%,  slightly  lagging its peer group average of
2.68%.(1)

CONTRIBUTORS TO PERFORMANCE IN THE FIRST HALF

The Series  underperformed in the first quarter of 1997 primarily because of its
position in property and casualty insurer Home Holdings. This company, which was
beset with problems among some of its insured risks, continued to lose value and
was ultimately sold from the portfolio.

While the first quarter's total return was negative, the second quarter was much
improved.  Steps  were  taken to  upgrade  the  overall  credit  quality  of the
holdings.  The high yield portion of the portfolio is now concentrated in issues
rated BB and B, the upper tiers of the high yield rating universe. Some of these
issues have the  potential  to be upgraded to  investment  grade  ratings in the
not-too-distant  future, which should add a capital gain return element to their
attractive coupon rates.

HOW THE PORTFOLIO LOOKS NOW

The sector  composition of the portfolio at the end of June was about 53.5% high
grade  corporate  bonds,   20%  high  yield  issues,   17%  Yankee  bonds  (U.S.
dollar-denominated   securities  issued  by  foreign  corporations),   and  9.5%
mortgage-backed bonds issued primarily by agencies of the U.S. Government.  This
sector  diversification gives the portfolio some downside protection because the
various sectors will not always move up or down in value in tandem.

The average  rating of the portfolio is a strong BBB, and the average  coupon of
the portfolio holdings is 7.92%. Average duration of the securities is about 6.6
years,  slightly longer than that of the benchmark  Lehman  Corporate Bond Index
duration of 5.88 years. We are working to reduce the block size of issues in the
portfolio so that each issuer will  represent  2.5% or less of total assets,  in
order to achieve further diversification.

LOOKING TO THE SECOND HALF

The Corporate Bond Series'  portfolio is well  positioned for the coming months.
Our emphasis on upgrading credit quality should help bring total returns more in
line with those of the benchmark index. Diversification among sectors and rating
classes can add a further element of safety. The mortgage-backed  securities and
Yankee bonds provide cash flow through their  generally  higher coupon  interest
rates than other classes.  Finally,  fundamentally  improving  stories among our
high yield credits  provide the potential for additional  return through capital
gains.

MANAGER'S COMMENTARY
AUGUST 15, 1997



U.S. GOVERNMENT SERIES

The U.S.  Government  Series of Security Income Fund returned 2.46% in the first
half of 1997,  right in line with its peer group  average  return of 2.47%.1 The
benchmark Lehman Government Bond Index returned a slightly higher 2.63% over the
same period.

CONTRIBUTORS TO PERFORMANCE

The portfolio had a large  weighting in  longer-duration  Federal  agency bonds,
with  moderate   positions  in  shorter  Treasury  issues  and   mortgage-backed
securities  throughout  the first six  months.  During  the  first  quarter  the
Treasuries and  mortgage-backed  bonds provided downside  protection and allowed
the total return to be higher  (actually,  less  negative) than that of the peer
group of funds. In March, April and May, however, the bond markets recovered and
these same defensive  issues  dampened  returns  somewhat,  holding back overall
performance.

PORTFOLIO COMPOSITION AT THE END OF THE FIRST HALF

The sector weighting in the Series  consisted of 41% federal agency  securities,
36% GNMA mortgage-backed bonds secured by home mortgages,  and 23% U.S. Treasury
issues.  In general,  mortgage-backed  bonds and  federal  agency  issues  carry
slightly higher coupon rates than comparable  Treasury bonds.  This adds a small
extra increment to total return.

The duration of the  portfolio at the end of June was 4.85 years,  close to that
of the benchmark  index's duration of 4.78 years.  The average coupon,  however,
was  considerably  higher  than that of the index at  8.15%,  compared  with the
benchmark's 6.95% average.

PLANS FOR THE NEXT SIX MONTHS

The U.S. Government Series is designed for conservative investors, with a strong
emphasis on credit  quality of the  securities  held in the  portfolio.  Because
shareholders  in the Series tend to be  cautious,  we don't try to outguess  the
markets by  dramatically  lengthening  or  shortening  the duration of portfolio
holdings.

In the coming months, we anticipate  maintaining our sector allocations close to
their  present  levels.  We expect  portfolio  durations to also remain close to
current  lengths.  As always,  we keep an eye on the  markets to watch for sharp
movements in either  direction,  and retain the ability to make  stronger  moves
than usual if it becomes necessary.

MANAGER'S COMMENTARY
AUGUST 15, 1997


LIMITED MATURITY BOND SERIES

Throughout a period of volatility in the bond markets, the Limited Maturity Bond
Series  performed  very well in the first half of 1997.  The  Series  produced a
total return of 3.20%, comparing favorably with its peer group average of 2.74%,
and  outperforming  its benchmark  Lehman Brothers  Intermediate  Corporate Bond
Index return of 3.05%.(1)  The ten-year  Treasury  bond,  representative  of the
maturity  structure of this portfolio,  began the year yielding  6.42%,  touched
6.90% in late  March and early  April,  and fell back to close the first half at
6.50%.

CONTRIBUTORS TOWARD STRONG PERFORMANCE

Several of the high yield holdings in the portfolio  experienced strong earnings
and  strengthened  balance  sheets  through  debt  reduction  over the first six
months. These include PanAmerican Beverages, Inc., a Latin American producer and
bottler of Coca Cola and other soft drinks. Valassis Communications Corporation,
a company  that  produces  special  coupon  inserts  for Sunday  newspapers,  is
generally  expected to be upgraded to investment  grade in the near future after
reducing expenses and benefiting from lower paper costs.

Seagull Energy Corporation,  an oil and gas explorer and developer,  has lowered
overall company costs, realizing benefits of a recent acquisition.  It is now on
Standard & Poor's  ratings  watch list for an upgrade.  Comcast  Corporation,  a
cable television and  telecommunications  company, was upgraded to BB just after
the close of the first half.

COMPOSITION OF THE PORTFOLIO

The Limited Maturity Bond Series is currently  comprised of about 46% high grade
bonds, 23% high yield issues (the maximum high yield allocation permitted in the
portfolio is 25%), 22%  mortage-backed  securities  issued  primarily by Federal
government agencies,  and 9% Yankee bonds (dollar denominated  securities issued
by foreign corporations).

The portfolio duration is approximately 4.3 years, just slightly longer than the
benchmark  index's 4.21 years.  The average  coupon is a  relatively  high 8.1%,
lifted by the high yield and mortgage-backed  securities  holdings.  The average
rating of securities remains well within the investment grade  classification at
a mid-A level.

WHAT'S AHEAD FOR THE LIMITED MATURITY PORTFOLIO

We plan to maintain the overall  portfolio  quality at its present level, and to
keep the duration  close to that of the benchmark  intermediate  corporate  bond
index. The broad diversification of asset classes should help keep volatility at
lower levels, since the various sectors will not always move up or down in value
in tandem with each other.  The  intermediate-maturity  bond  portfolios tend to
outperform their longer counterparts in periods of rising interest rates, and so
make an attractive investment medium for a portion of shareholders' fixed income
allocations.

MANAGER'S COMMENTARY
AUGUST 15, 1997


HIGH YIELD SERIES

The high  yield  segment of the fixed  income  markets  was the  best-performing
domestic bond sector during the first half of 1997. The High Yield Series ranked
above  median in its peer group,  returning  5.79% for the  period.(1)  The peer
group average return was 5.92%,  while the benchmark  Lehman Brothers High Yield
Index posted a return of 5.82%.

COMPOSITION OF THE PORTFOLIO

At the end of June the High Yield  Series  portfolio  was  skewed  toward the BB
rating  category,  the highest level on the high yield bond rating  scale.  With
approximately 70% of the issues in this category and the remaining ones rated B,
we feel  that  there is less  concern  about  credit  risk and more  ability  to
liquidate easily should selling become  necessary.  Our analysts seek out issues
which are currently  rated BB, but whose financial  statements show  improvement
that could lead to an upgrade to investment grade in the near future.

Throughout the six months the portfolio has been underweight in basic industries
such  as  mining,   metals,  and  chemicals,   which  have  for  the  most  part
underperformed  other sectors.  We were overweight in consumer  cyclicals (cable
television  companies,   retail  stores,  gaming,  and  home  construction)  and
financials, including banks and insurance companies. Our underweight position in
utility bonds hurt, as this sector did very well during the period.

CONTRIBUTORS TO STRONG PERFORMANCE

Some  issues  in the  portfolio  were  upgraded  by the  major  rating  agencies
recently.  Knoll,  Inc., which  manufactures and distributes  office systems and
business furniture,  brought an initial public offering (IPO) to market and used
the proceeds to pay down more  expensive  debt.  The company's  securities  were
subsequently  upgraded from a low B to a high B level.  Comcast  Corporation,  a
cable television and  telecommunications  company, was upgraded to BB just after
the close of the first half of 1997.

Other strong performers included AGCO Corporation,  a worldwide manufacturer and
distributor of agricultural  equipment and related  replacement  parts. AGCO has
benefited  from the strong  farm  economy,  both in the U.S.  and  abroad.  Four
Seasons Hotels, Inc. offered to repurchase its 9.125% notes at a price which was
very attractive relative to their cost in our portfolio.

PLANS FOR THE REST OF 1997

We intend to continue  our strategy of staying  cognizant of credit  quality and
looking for bonds which have a potential of being upgraded from BB to investment
grade.  The high yield bond  markets are  similar to the equity  markets in that
they have risen a good deal, but  investment  funds continue to pour in, driving
them up further.  We plan to structure  the  portfolio to be sound from a credit
standpoint so that it can better withstand any unforseen shocks to the market.

MANAGER'S COMMENTARY
AUGUST 15, 1997


SECURITY TAX-EXEMPT FUND

The  municipal  market in the first half of the year  outperformed  its  taxable
counterparts in the domestic fixed income markets. The Lehman Brothers Municipal
Bond Index rose 3.20% during the period, outpacing the Lehman Brothers Aggregate
Fixed Income Index return of 3.09%.  The corporate and government  components of
the aggregate index also showed lower returns than those of the municipal index.

PORTFOLIO PERFORMANCE IN THE FIRST HALF

The Security Tax-Exempt Fund produced a positive total return of 2.58%, modestly
underperforming  its peer  group  average  of 2.95% for the six  months.(1)  Our
somewhat  shorter  duration  of 6.9 years,  compared  with the  benchmark  index
duration  of  7.42  years,  held  back  performance  in the  latter  part of the
six-month  period when interest rates were falling.  Longer  maturities  tend to
outperform shorter bonds in such an interest rate environment.

The average credit quality of the bonds in the portfolio,  currently at a mid-AA
level, while providing comfort to investors because of its strength,  also holds
back  performance  when interest  rates are declining.  We generally  maintain a
higher-than-average   portfolio  rating  since  financial  information  on  many
municipal  issuers is difficult to obtain,  and  sometimes  not timely enough to
protect  investors when finances  deteriorate.  In addition,  if  municipalities
experience  strains on their budgets when Congress "pushes down" budget items to
the state and local levels,  those bonds with higher credit  quality should hold
their value better.

THE COMPOSITION OF THE PORTFOLIO CURRENTLY

The  Security  Tax-Exempt  Fund  seeks  to  add  a  measure  of  safety  through
diversification. In municipal portfolios, this means including a large number of
geographic  locations  as well as  diversifying  by  industry.  At June 30,  the
holdings  represented  17 states  plus the  District  of  Columbia.  The largest
represented,  in terms of  market  value of the  bonds,  was  Washington  State,
followed by Illinois and California.

In terms of industry  classification,  the  largest  grouping of bonds is in the
Education  Revenue  sector.  Education  issues  are  viewed  favorably  by  most
municipal bond holders,  since municipalities are highly likely to support their
school systems and avoid bond defaults in this area.  Second largest is Electric
Utility Revenue,  another area where cash inflows to retire bonds are considered
relatively stable.

OUTLOOK FOR MUNICIPAL BONDS

A  constant  threat  to the  value of tax  exempt  bonds is talk of tax  bracket
reductions.  While various tax "breaks" are under discussion in Congress as they
try to agree on a balanced budget package,  a lowering of tax brackets for those
individuals  most likely to invest in  municipal  bonds  seems  unlikely at this
time. We believe that tax exempt bonds  continue to be an attractive  investment
for taxpayers in the upper brackets, and should be for some time to come.

MANAGER'S COMMENTARY
AUGUST 15, 1997


SECURITY CASH FUND

The total  return on money  market funds in the first half of 1997 was near that
of its close relatives, the fixed income funds, as interest rates on thirty-year
Treasury bonds  fluctuated in a range roughly between 6.50% and 7.25%.  Security
Cash Fund posted a gain of 2.36% for the period,  very near the 2.38% peer group
average yield.  Money market funds,  unlike longer-term fixed income securities,
generally  benefit from  increases in short-term  interest rates such as the one
executed by the Federal Reserve Open Market Committee in March.

AVERAGE MATURITY TARGETS FOR THE FUND

At June 30, the Cash Fund had a 61-day average maturity,  seven days longer than
that of the benchmark IBC Donoghue Money Fund Report. Our goal is to stay within
ten days more or less than the Donoghue average and avoid trying to outguess the
markets  by  moving  maturities  sharply  shorter  or  longer.  Because  of  the
short-maturity  nature of money market assets we can quickly  adjust to interest
rate changes when they occur,  without taking unnecessary  maturity risk in this
conservative portfolio.

ASSET SECTORS REPRESENTED IN THE PORTFOLIO

The assets in Security Cash Fund at the end of the six-month period consisted of
76%  commercial  paper,  15% federal agency  securities,  and 11% Small Business
Administration  issues. The commercial paper we purchase is entirely in the "top
tier" of rating agency classifications, rated at least A1 by Standard and Poor's
rating agency or P1 by Moody's.  Federal  agency  holdings may from time to time
include   short-term   securities   issued  by  the  Federal  National  Mortgage
Association, the Federal Home Loan Bank, and Federal Farm Credit Banks.

The Small  Business  Association  (SBA)  holdings  are fully  guaranteed  by the
federal government as to timely payment of principal and interest. These issues,
while  bearing  stated  maturities  in the  twenty- to  thirty-year  range,  are
considered  to be  short-maturity  paper  because  their  interest  rate  resets
periodically  (usually  monthly or quarterly).  This enables the issues to carry
coupons  representing  recent  market  levels,  staying  competitive  with other
short-term investment instruments.

OUTLOOK FOR THE NEXT SIX MONTHS

Interest  rates have recently been declining on long-term  bonds.  Although this
movement has some effect on short-term rates,  until the Federal Reserve decides
to lower their short rate targets,  commercial paper and  short-maturity  agency
interest  rates  should not drop  substantially.  We expect the Fed to  maintain
their  cautious  stance  toward a  rekindling  of  inflationary  pressures,  and
therefore  believe that money fund returns  will not vary  substantially  in the
near future.


Barbara Davison
Fixed Income Team

The Security Cash Fund is neither insured nor guaranteed by the U.S.  Government
and there is no  assurance  that the fund will be able to  maintain a stable net
asset value of $1.00 per share.

NOTES TO FINANCIAL STATEMENTS
JUNE 30, 1997
(UNAUDITED)


1.  SIGNIFICANT ACCOUNTING POLICIES

     Security Income Fund,  Security Tax-Exempt Fund and Security Cash Fund (the
Funds) are registered under the Investment  Company Act of 1940, as amended,  as
diversified  open-end management  investment  companies.  The shares of Security
Income  Fund are  currently  issued in multiple  series,  with each  series,  in
effect, representing a separate Fund. The Income Fund is required to account for
each series  separately  and to allocate  general  expenses to each series based
upon the net asset  value of each  series.  The  following  is a summary  of the
significant  accounting  policies  followed by the Funds in the  preparation  of
their  financial  statements.  These  policies are in conformity  with generally
accepted accounting principles.

     A. SECURITY  VALUATION - Valuations of Income Funds' and Tax-Exempt  Fund's
securities are supplied by pricing services  approved by the Board of Directors.
Securities listed or traded on a national  securities exchange are valued on the
basis of the last sales price.  If there are no sales on a particular  day, then
the  securities  are valued at the last bid price.  Securities  for which market
quotations are not readily available are valued by a pricing service considering
securities with similar yields,  quality,  type of issue,  coupon,  duration and
rating.  If  there  is no  bid  price  or if  the  bid  price  is  deemed  to be
unsatisfactory  by the Board of Directors or by the Funds'  investment  manager,
then the  securities  are  valued in good  faith by such  method as the Board of
Directors determines will reflect the fair value. The Funds' officers, under the
general supervision of the Board of Directors,  regularly review procedures used
by, and valuations provided by, the pricing service.

     Cash Fund,  by approval of the Board of  Directors,  utilizes the amortized
cost method for valuing portfolio securities, whereby all investments are valued
by reference to their  acquisition  cost as adjusted for amortization of premium
or accretion of discount.

     B.  OPTIONS - The High Yield bond Series may  purchase put and call options
and write  such  options  on a covered  basis on  securities  that are traded on
recognized  securities  exchanges  and  over-the-counter  markets.  Call and put
options  on  securities   give  the  holder  the  right  to  purchase  or  sell,
respectively (and the writer the obligation to sell or purchase),  a security at
a specified  price,  on or until a certain date.  The primary risks  associate d
with the use of  options  are an  imperfect  correlation  between  the change in
market value of the  securities  held by the Series and the price of the option,
the possibility of an illiquid market, and the inability of the counter-party to
meet the terms of the contract.

     The premium received for a written option is recorded as an asset,  with an
equal  liability  which is marked to market based on the  option's  quoted daily
settlement  price.  Fluctuation in the value of such instruments are recorded as
unrealized appreciation  (depreciation) until terminated, at which time realized
gains and losses are recognized.

     C. SECURITY  TRANSACTIONS AND INVESTMENT INCOME - Security transactions are
accounted for on the date the securities  are purchased or sold.  Realized gains
and  losses  are  reported  on  an  identified  cost  basis.Interest  income  is
recognized on the accrual basis.  Premium and discounts  (except  original issue
discounts) on debt securities are not amortized, except Security Tax-Exempt Fund
which amortizes premiums.

     D.  DISTRIBUTIONS  TO  SHAREHOLDERS -  Distributions  to  shareholders  are
recorded on the ex-dividend date. The character of distributions made during the
year from net  investment  income or net  realized  gains may differ  from their
ultimate characterization for federal income tax purposes. These differences are
primarily due to the recharacterization of foreign currency gains and losses.

     E. TAXES - The Funds complied with the requirements of the Internal Revenue
Code applicable to regulated  investment  companies and distributed all of their
taxable net income and net realized  gains  sufficient to relieve them from all,
or substantially all, federal income, excise and state income taxes.  Therefore,
no provision for federal or state income tax is required.

     F. EARNINGS CREDITS - Under the fee schedule with the custodian,  the Funds
earn  credits  based on  overnight  custody  cash  balances.  These  credits are
utilized to reduce related custodial  expenses.  The custodian fees disclosed in
the  statement of  operations  do not reflect the  reduction in expense from the
related earnings credits.

2.  MANAGEMENT FEES AND OTHER TRANSACTIONS WITH AFFILIATES

     Management fees are payable to Security Management Company, LLC (SMC) under
investment  advisory contracts at an annual rate of .50 of 1% of the average net
assets of each fund, except for the High Yield Bond Series whose fees are .60 of
1% of the average net assets of the Series. The investment advisory contract for
Income Fund provides  that the total annual  expenses of each Series of the Fund
(including  management  fees and  custodian  fees net of earnings  credits,  but
excluding interest,  taxes,  brokerage  commissions and extraordinary  expenses)
will not exceed the level of expenses  which  Income Fund is  permitted  to bear
under the most  restrictive  expense  limitation  imposed  by any state in which
shares of the Fund are then  qualified  for sale.  For the period ended  June30,
1997,  SMC agreed to limit the total  expenses of Corporate  Bond  Series,  U.S.
Government  Series and Limited Maturity Bond Series to an annual rate of 1.1% of
the average  daily net asset value of Class A shares and 1.85% of Class B shares
of each  respective  Series.  SMC also agreed to limit the total expenses of the
High Yield Bond  Series to 2.0% for Class A Shares and 2.75% for Class B shares.
In  addition,  SMC  agreed  to  waive  all of the  management  fees for the U.S.
Government  Series,  Limited Maturity Bond Series and the High Yield Bond Series
until  December 31, 1997. The  investment  advisory  contract for Tax-Exempt and
Cash Funds provides that the total annual expenses of the Funds net of custodian
fee  earnings  credits will not exceed an amount equal to an annual rate of 1.0%
of the  average  net  assets of Class A shares and 2.0% of Class B shares of the
Tax-Exempt Fund as calculated on a daily basis.

     The Funds have entered into  contracts with SMC for transfer agent services
and certain other  administrative  services which SMC provides to the Funds. SMC
is paid an  annual  fixed  charge  per  account  and  shareholder  and  dividend
transaction fees.

     As the  administrative  agent for the Funds,  SMC  performs  administrative
functions, such as regulatory filings, bookkeeping,

                                       26

accounting and pricing functions for the Funds. For this service SMC receives on
an annual basis, a fee of .09% of the average daily net assets of Corporate Bond
Series,  U.S.  Government Series,  Limited Maturity Bond Series, High Yield Bond
Series,  and  Tax-Exempt  Fund and .045% of the average daily net assets of Cash
Fund calculated daily and payable monthly.

     Income and Tax-Exempt Funds have adopted  Distribution Plans related to the
offering of Class B shares  pursuant to Rule 12b-1 under the Investment  Company
Act of 1940.  The Plans  provide  for  payments at an annual rate of 1.0% of the
average net assets of Class B shares.  Class A shares of Income Fund incur 12b-1
distribution  fees at an annual  rate of .25% of the  average net assets of each
Series.

     Security  Distributors,  Inc. (SDl), a wholly-owned  subsidiary of Security
Benefit  Group,  Inc.,  a  financial  services  holding  company,   is  national
distributor  for Income and  Tax-Exempt  Funds.  SDI received  net  underwriting
commissions  on sales of Class A shares and  contingent  deferred  sales charges
(CDSC) on redemptions  occurring within 5 years of the date of purchase of Class
B shares,  after  allowances to brokers and dealers for the period ended June30,
1997, in the amounts presented below:
