You also can find the most current price of your shares in the business section
of your newspaper in the mutual fund section under the heading "USAA Group" and
the symbol "AgvGt."  

You may see the Fund's total return quoted in advertisements  and reports.  All
mutual funds must use the same formula to calculate total return.  Total return
measures the price change in a share assuming the  reinvestment of all dividend
income and capital gain  distributions.  You may also see a  comparison  of the
Fund's  performance  to that of other  mutual  funds  with  similar  investment
objectives and to stock or relevant indexes.

For the following  periods ended  September 30, 1997, the Fund's average annual
total returns have been:
   
               1 Year..................................  12.97%
               5 Years.................................  22.01%
              10 Years.................................  12.58%
    

Figures  on page 5 are  different  because  they are for  periods  which  ended
December 31, 1996. 

WILL THE VALUE OF YOUR INVESTMENT FLUCTUATE? 
   
Yes, it will. The value of your  investment  could increase or decrease.  While
the  portfolio  will  be  broadly  diversified,  the  Fund  is  expected  to be
significantly  more volatile than the average equity mutual fund.  Investing in
smaller less well-known companies,  especially those that have a narrow product
line or are traded infrequently,  often involves greater risk than investing in
established  companies with proven track records. The bar chart and table shown
on the next page illustrate the Fund's  volatility and performance from year to
year over the past ten years and shows how the Fund's  average  annual  returns
for the one-,  five-,  and ten-year  periods  compare to those of a broad-based
securities market index. Again,  remember  historical  performance might not be
repeated in the future.

A WORD ABOUT RISK

Portions of this Prospectus  describe the risks you will face as an investor in
the  Fund.  Keep in mind that  generally  investments  with a higher  potential
reward also have a higher risk of losing money.  The reverse is also  generally
true:  the lower the risk,  the lower the  potential  reward.  However,  as you
consider an  investment  in the Fund,  you should also take into  account  your
tolerance for the daily  fluctuations of the financial  markets and whether you
can afford to leave your money in this  investment  for long periods of time to
ride out down periods.  

[CAUTION LIGHT GRAPHIC]
Look for this symbol  throughout  the  Prospectus.  We use it to mark  detailed
information about the main risks that you will face as a Fund shareholder.

FUND INVESTMENTS

Investment Policies and Risks

   Q    What is the Fund's investment policy?

   A    We will invest the Fund's  assets  primarily  in equity  securities  of
        companies  that have the prospect of rapidly  growing  earnings.  These
        investments will tend to be made in smaller, less recognized companies,
        but may include larger,  more widely  recognized  companies as well. We
        use the term "equity  securities" to include  common stocks,  preferred
        stocks, securities convertible into common stocks, and securities which
        carry the right to buy common  stocks.  We may also invest up to 10% of
        the Fund's assets in shares of real estate investment trusts (REITs).
   
        As a  temporary  defensive  measure,  we may  invest  up to 100% of the
        Fund's assets in high-quality, short-term debt instruments.

        We will not  generally  trade  the  Fund's  securities  for  short-term
        profits;  however,  if circumstances  warrant, we may purchase and sell
        Fund  securities  without regard to the length of time held. The Fund's
        portfolio turnover rate will vary from year to year depending on market
        conditions,  and it may  exceed  100%.  Because  a high  turnover  rate
        increases  transaction costs and may increase taxable capital gains, we
        will carefully weigh the anticipated benefits of trading.
    
[CAUTION LIGHT GRAPHIC]
MARKET RISK. Because this Fund invests in equity  securities,  it is subject to
market risk.  Stock  prices in general may decline over short or even  extended
periods,  regardless  of the  success  or failure  of an  individual  company's
operations.  The stock market  tends to run in cycles,  with periods when stock
prices generally go up and periods when stock prices generally go down.  Equity
securities tend to go up and down more than bonds.

[CAUTION LIGHT GRAPHIC]
REITS.  Investing  in REITs  may  subject  the  Fund to many of the same  risks
associated with the direct  ownership of real estate.  REITs are dependent upon
the capabilities of the REIT manager(s) and have limited diversification.

   Q   May the Fund's assets be invested in foreign securities?

   A   Yes.  While  most  of  the  Fund's  assets  will  be  invested  in  U.S.
       securities,  we may also invest up to 30% of the Fund's  total assets in
       foreign  securities,  including American  Depositary Receipts (ADRs) and
       Global  Depositary  Receipts (GDRs).  These foreign holdings may include
       securities  issued in emerging  markets as well as securities  issued in
       established markets.

                                       6
<PAGE>

[CAUTION LIGHT GRAPHIC]
FOREIGN INVESTING. Investing in foreign securities poses unique risks: currency
exchange  rate  fluctuations;   foreign  market  illiquidity;  increased  price
volatility;  exchange control regulations;  foreign ownership limits; different
accounting,   reporting,  and  disclosure  requirements;  and  difficulties  in
obtaining legal judgments.  In the past, equity and debt instruments of foreign
markets  have been more  volatile  than  equity  and debt  instruments  of U.S.
securities  markets. 

[CAUTION LIGHT GRAPHIC] 
EMERGING  MARKETS  RISK.  A  country  that  is in  the  initial  stages  of its
industrial cycle is considered to be an emerging  markets country.  Investments
in  developing  countries  involve  exposure  to economic  structures  that are
generally  less  diverse and mature than in the United  States and to political
systems which may be less stable. In the past, markets of developing  countries
have been more volatile than the markets of developed countries.

[CAUTION LIGHT GRAPHIC]
POLITICAL RISK.  Political risk includes a greater  potential for coup d'etats,
revolts, and expropriation by governmental  organizations.  For example, we may
invest the  Fund's  assets in  Eastern  Europe and former  states of the Soviet
Union (also known as the  Commonwealth  of  Independent  States or CIS).  These
countries were under communist systems which had nationalized private industry.
There is no guarantee that  nationalization  may not occur again in this region
or others in which we may invest the Fund's assets,  in which case, we may lose
all or part of the Fund's investment in that country's issuers.  
   
For additional  information  about other  securities in which we may invest the
Fund's assets, see APPENDIX A on page 17.
    
Investment Restrictions

The following restrictions may only be changed with shareholder approval:

o    The Fund may not invest more than 25% of its total assets in one industry.

o    The Fund may not invest more than 5% of its total assets in any one issuer
     or own  more  than 10% of the  outstanding  voting  securities  of any one
     issuer. This limitation does not apply to U.S. Government securities,  and
     only applies to 75% of the Fund's total assets.

o    The Fund may borrow only for temporary or emergency  purposes in an amount
     not exceeding 33 1/3% of its total assets.

You will find a complete listing of the precise investment  restrictions in the
Fund's Statement of Additional Information.

FUND MANAGEMENT
   
The Board of Directors of USAA Mutual Fund, Inc.  (Company),  of which the Fund
is a series,  supervises the business  affairs of the Company.  The Company has
retained us, USAA Investment  Management  Company,  to serve as the manager and
distributor for the Company. 

We are an affiliate of United Services Automobile  Association (USAA), a large,
diversified financial services institution.  As of the date of this Prospectus,
we had approximately $36 billion in total assets under management.  Our mailing
address is 9800 Fredericksburg Road, San Antonio, TX 78288.
    
We are responsible for managing the Fund's  portfolio  (including  placement of
brokerage  orders) and its business  affairs,  subject to the  authority of and
supervision  by the Board of Directors.  For our services,  the Fund pays us an
annual fee. This fee, which is accrued daily and paid monthly, is computed as a
percentage  of average  net  assets.  The fee is  computed  at  one-half of one
percent  (.50%) of the first $200 million of average net assets,  two-fifths of
one  percent  (.40%) for that  portion of average  net assets in excess of $200
million but not over $300 million, and one-third of one percent (.33%) for that
portion of average net assets in excess of $300  million.  The fees we received
for the  fiscal  year ended July 31,  1997,  were equal to .39% of average  net
assets.  

We also provide  services  related to selling the Fund's  shares and receive no
compensation for those services.

Although  our  officers and  employees,  as well as those of the  Company,  may
engage  in  personal  securities  transactions,  they  are  restricted  by  the
procedures in a Joint Code of Ethics adopted by the Company and us.

Portfolio Transactions

USAA Brokerage Services,  our discount brokerage service, may execute purchases
and sales of equity securities for the Fund's portfolio. The Board of Directors
has adopted  procedures to ensure that any  commissions  paid to USAA Brokerage
Services are reasonable and fair.

Portfolio Managers

The following individuals are primarily responsible for managing the Fund. John
K.  Cabell,  Jr.  and  Eric M.  Efron,  Assistant  Vice  Presidents  of  Equity
Investments since September 1996, have managed the Fund since March 1995.
   
Mr. Cabell has 19 years investment  management experience and has worked for us
for eight years. He served as Chief Economist for Retirement Systems of Alabama
from March 1991 to March 1994. He earned the Chartered  Financial Analyst (CFA)
designation  in  1982  and  is a  member  of  the  Association  for  Investment
Management and Research (AIMR) and the San Antonio Financial  Analysts Society,
Inc.(SAFAS). He holds an MA and a BS from the University of Alabama.

USING MUTUAL FUNDS IN
AN INVESTMENT PROGRAM

I. The Idea Behind Mutual Funds

Mutual funds provide small investors some of the advantages  enjoyed by wealthy
investors.  A  relatively  small  investment  can  buy  part  of a  diversified
portfolio. That portfolio is managed by investment professionals, relieving you
of the  need to make  individual  stock  or bond  selections.  You  also  enjoy
conveniences,  such as daily  pricing,  liquidity,  and in the case of the USAA
Family of Funds, no sales charge. The portfolio, because of its size, has lower
transaction  costs on its trades than most individuals would have. As a result,
you own an investment  that in earlier times would have been  available only to
very wealthy people.

II. Using Funds in an Investment Program

In  choosing a mutual  fund as an  investment  vehicle,  you are giving up some
investment decisions,  but must still make others. The decisions you don't have
to make are those involved with choosing individual securities. We will perform
that function.  In addition, we will arrange for the safekeeping of securities,
auditing the annual financial  statements,  and daily valuation of the Fund, as
well as other functions.

You,  however,  retain  at  least  part of the  responsibility  for an  equally
important  decision.  This decision involves  determining a portfolio of mutual
funds that balances your  investment  goals with your tolerance for risk. It is
likely that this decision may include the use of more than one fund of the USAA
Family of Funds.

For example,  assume you wish to invest in a  widely-diversified,  common stock
portfolio.  You could combine an investment in the Aggressive  Growth Fund with
investments  in other  mutual  funds  that  invest in stocks of large and small
companies  and  high-dividend  stocks.  This is just one way you could  combine
funds that fit your own risk and reward goals.

III. USAA's Family of Funds
   
We offer you another  alternative for asset  allocation with our asset strategy
funds  listed on page 18. These unique  mutual funds  provide a  professionally
managed  diversified  investment  portfolio  within  a  mutual  fund.  They are
designed  for the  individual  who  prefers to  delegate  the asset  allocation
process to an investment manager and are structured to achieve  diversification
across a number of investment categories.

Whether you prefer to create  your own mix of mutual  funds or use a USAA Asset
Strategy  Fund,  the USAA  Family of Funds  provides  a broad  range of choices
covering  just  about  any   investor's   investment   objectives.   Our  sales
representatives  stand  ready to assist you with your  choices  and to help you
craft a portfolio which meets your needs. 

HOW TO INVEST

Purchase of Shares

OPENING AN ACCOUNT
   
You may open an account and make an investment  as described  below by mail, in
person,  bank wire,  electronic  funds  transfer  (EFT),  or phone. A complete,
signed  application  is  required  for each new  account.  
    
TAX ID NUMBER  
Each shareholder  named on the account must provide a social security number or
tax identification number to avoid possible withholding requirements.

EFFECTIVE  DATE
When you make a purchase, your purchase price will be the net asset value (NAV)
per share next  determined  after we  receive  your  request in proper  form as
described  below.  The Fund's  NAV is  determined  at the close of the  regular
trading  session  (generally  4:00  p.m.  Eastern  Time) of the New York  Stock
Exchange  (NYSE) each day the NYSE is open. If we receive your request prior to
that time,  your purchase  price will be the NAV per share  determined for that
day. If we receive  your  request  after the NAV per share is  calculated,  the
purchase  will be effective on the next  business  day. If you plan to purchase
Fund shares with a foreign check,  we suggest you convert your foreign check to
U.S.  dollars prior to investment in the Fund to avoid a potential delay in the
effective date of your purchase of up to four to six weeks. Furthermore, a bank
charge may be assessed in the clearing process, which will be deducted from the
amount of the purchase.

MINIMUM INVESTMENTS  

INITIAL PURCHASE 
[MONEY GRAPHIC]      o $3,000  [$500  Uniform  Gifts/Transfers  to  Minors  Act
                       (UGMA/UTMA)  accounts  and $250 for IRAs] or no  initial

Redemption of Shares

You may redeem Fund shares by any of the methods described below on any day the
NAV per share is calculated.  Redemptions are effective on the day instructions
are received in a manner as  described  below.  However,  if  instructions  are
received  after  the NAV per share  calculation  (generally  4:00 p.m.  Eastern
Time), redemption will be effective on the next business day.

Within seven days after the effective date of redemption, we will send you your
money. Payment for redemption of shares purchased by EFT or check is sent after
the EFT or check has cleared,  which could take up to 15 days from the purchase
date. If you are considering  redeeming shares soon after purchase,  you should
purchase by bank wire or certified check to avoid delay.

In  addition,  the  Company may elect to suspend  the  redemption  of shares or
postpone the date of payment in limited circumstances.

IMPORTANT INFORMATION ABOUT PURCHASES AND REDEMPTIONS

Investor's Guide to USAA Mutual Fund Services

Upon your initial  investment with us, you will receive the INVESTOR'S GUIDE to
help you get the most out of your USAA mutual  fund  account and to help you in
your role as an investor.  In the INVESTOR'S  GUIDE,  you will find  additional
information on purchases, redemptions,

                                      12
<PAGE>

and methods of payment.  You will also find in-depth  information  on automatic
investment  plans,   shareholder  statements  and  reports,  and  other  useful
information.

Account Balance

Beginning in September  1998,  and occurring each  September  thereafter,  USAA
Shareholder  Account Services (SAS),  the Fund's transfer agent,  will assess a
small balance account fee of $12 to each shareholder account with a balance, at
the time of assessment, of less than $2,000. The fee will reduce total transfer
agency fees paid by the Fund to SAS. Accounts exempt from the fee include:  (1)
any  account  regularly  purchasing  additional  shares  each month  through an
automatic  investment  plan;  (2) any  account  registered  under  the  Uniform
Gifts/Transfers to Minors Act (UGMA/UTMA);  (3) all (non-IRA) money market fund
accounts;  (4) any account whose registered  owner has an aggregate  balance of
$50,000 or more  invested in USAA mutual  funds;  and (5) all IRA accounts (for
the first year the account is open).

Company Rights

The Company reserves the right to:

o    reject  purchase  or  exchange  orders  when in the best  interest  of the
     Company;

o    limit or  discontinue  the  offering  of  shares of any  portfolio  of the
     Company without notice to the shareholders;

o    impose a  redemption  charge of up to 1% of the net asset  value of shares
     redeemed  if  circumstances   indicate  a  charge  is  necessary  for  the
     protection of remaining investors (for example, if excessive market-timing
     share activity unfairly burdens  long-term  investors);  however,  this 1%
     charge will not be imposed  upon  shareholders  unless  authorized  by the
     Board of Directors and the required notice has been given to shareholders;
     
o    require a  signature  guarantee for purchases,  redemptions, or changes in
     account  information in those  instances  where the  appropriateness  of a
     signature  authorization  is in  question.  The  Statement  of  Additional
     Information contains information on acceptable guarantors;

o    redeem an account with less than 10 shares, with certain limitations.

EXCHANGES

Exchange Privilege

The exchange privilege is automatic when you complete your application. You may
exchange  shares  among Funds in the USAA Family of Funds,  provided you do not
hold these shares in stock  certificate  form and the shares to be acquired are
offered  in  your  state  of  residence.   The  Fund's   transfer   agent  will
simultaneously process exchange redemptions and

                                      13
<PAGE>

purchases  at the share  prices next  determined  after the  exchange  order is
received.  For federal  income tax  purposes,  an exchange  between  Funds is a
taxable event; and as such, you may realize a capital gain or loss.

The Fund has undertaken certain procedures regarding telephone  transactions as
described on page 12.

Exchange Limitations, Excessive Trading
   
To  minimize  Fund costs and to protect the Funds and their  shareholders  from
unfair expense burdens,  the Funds restrict excessive  exchanges.  The limit on
exchanges  out of any Fund in the USAA Family of Funds for each  account is six
per calendar  year (except  there is no  limitation on exchanges out of the Tax
Exempt Short-Term Fund,  Short-Term Bond Fund, or any of the money market funds
in the USAA Family of Funds). 
    
SHAREHOLDER INFORMATION

Share Price Calculation

The price at which shareholders purchase and redeem Fund shares is equal to the
net asset  value  (NAV)  per  share  determined  on the  effective  date of the
purchase or  redemption.  You may buy and sell Fund shares at the NAV per share
without a sales charge.

When

The  Fund's NAV per share is  calculated  at the close of the  regular  trading
session of the NYSE, which is usually 4:00 p.m. Eastern Time.

How

The NAV per share is calculated by adding the value of all securities and other
assets in the Fund, deducting liabilities, and dividing by the number of shares
outstanding.

Dividends and Distributions

The Fund pays net  investment  income  dividends  yearly.  Any net capital gain
distribution  usually  occurs  within 45 days of the July 31  fiscal  year end,
which would be  somewhere  around the middle of  September.  The Fund will make
additional payments to shareholders,  if necessary,  to avoid the imposition of
any federal income or excise tax.

All  income  dividends  and  capital  gain   distributions   are  automatically
reinvested,  unless we receive different instructions from you. The share price
will be the NAV of the Fund shares computed on the ex-dividend date. Any income
dividends  or capital gain  distributions  paid by the Fund will reduce the NAV
per share by the amount of the dividend or  distribution.  These  dividends and
distributions are subject to taxes.

                                      14
<PAGE>

We will invest any  dividend  or  distribution  payment  returned to us in your
account at the  then-current NAV per share.  Dividend and  distribution  checks
become  void six months  from the date on the  check.  The amount of the voided
check will be invested in your account at the then-current NAV per share.

Federal Taxes

This tax  information  is quite  general and refers to the  federal  income tax
provisions in effect as of the date of this Prospectus.  Note that the recently
enacted Taxpayer Relief Act of 1997 and regulations that will likely be created
to  implement   the  Act  may  affect  the  status  and  treatment  of  certain
distributions  shareholders  receive from the Fund. We urge you to consult your
own tax  adviser  about the status of  distributions  from the Fund in your own
state and locality.

FUND - The Fund  intends to qualify as a  regulated  investment  company  (RIC)
under Subchapter M of the Internal Revenue Code of 1986, as amended.  As a RIC,
the Fund will not be subject to federal income tax on its net investment income
and net capital gains distributed to shareholders.  Net capital gains are those
gains in excess of capital losses.

SHAREHOLDER - Dividends from taxable net investment income and distributions of
net short-term  capital gains are taxable to shareholders  as ordinary  income,
whether received in cash or reinvested in additional shares. A portion of these
dividends may qualify for the 70%  dividends  received  deduction  available to
corporations.  

Regardless of the length of time you have held the Fund shares,distributions of
net  long-term  capital  gains are taxable as long-term  capital  gains whether
received in cash or reinvested in additional shares. 

Redemptions  and  exchanges  are subject to income tax based on the  difference
between  the  cost of  shares  when  purchased  and  the  price  received  upon
redemption or exchange.

WITHHOLDING  - Federal law  requires the Fund to withhold and remit to the U.S.
Treasury a portion of the income dividends and capital gain  distributions  and
proceeds of redemptions paid to any non-corporate shareholder who:

o    fails to furnish the Fund with a correct tax identification number,
o    underreports dividend or interest income, or
o    fails to certify that he or she is not subject to withholding.

To avoid this withholding requirement, you must certify on your application, or
on a separate  Form W-9 supplied by the Fund's  transfer  agent,  that your tax
identification  number is correct and you are not  currently  subject to backup
withholding.

REPORTING - The Fund will report annually to you information concerning the tax
status of dividends and distributions for federal income tax purposes.

                                      15

DESCRIPTION OF SHARES

The Fund is a series of USAA Mutual Fund,  Inc.  (Company) and is  diversified.
The Company is an open-end management investment company incorporated under the
laws of the State of  Maryland.  The Company is  authorized  to issue shares of
common  stock of separate  series,  each of which is commonly  referred to as a
mutual fund. There are ten mutual funds in the Company, including this Fund.
   
The Company does not hold annual or regular  meetings of shareholders and holds
special  meetings only as required by the  Investment  Company Act of 1940. The
Directors  may fill  vacancies  on the Board or appoint  new  Directors  if the
result is that at least  two-thirds of the Directors have still been elected by
shareholders.  Shareholders have one vote per share (with proportionate  voting
for  fractional  shares)  regardless  of the  relative  net asset  value of the
shares. If a matter affects an individual fund in the Company,  there will be a
separate  vote  of  the  shareholders  of  that  specific  fund.   Shareholders
collectively  holding at least 10% of the outstanding shares of the Company may
request a  shareholder  meeting at any time for the purpose of voting to remove
one or more of the Directors. The Company will assist in communicating to other
shareholders about the meeting.

                                   APPENDIX A

THE FOLLOWING ARE  DESCRIPTIONS  OF CERTAIN TYPES OF SECURITIES IN WHICH WE MAY
INVEST THE FUND'S ASSETS:  

CONVERTIBLE SECURITIES
   
We may invest in convertible securities, which are bonds, preferred stocks, and
other  securities that pay interest or dividends and offer the buyer the option
of  converting  the  security  into  common  stock.  The  value of  convertible
securities depends partially on interest rate changes and the credit quality of
the issuer. Because a convertible security affords an investor the opportunity,
through its conversion feature,  to participate in the capital  appreciation of
the underlying  common stock, the value of convertible  securities also depends
on the price of the underlying common stock.
    
FORWARD CURRENCY CONTRACTS  
We may hold  securities  denominated in foreign  currencies.  As a result,  the
value of the  securities  will be  affected  by  changes in the  exchange  rate
between the dollar and foreign  currencies.  In managing currency exposure,  we
may enter into forward currency contracts. A forward currency contract involves
an  agreement  to purchase or sell a specified  currency at a specified  future
date  or  over a  specified  time  period  at a  price  set at the  time of the
contract.  We only enter into forward  currency  contracts when the Fund enters
into a contract for the purchase or sale of a security  denominated  in foreign
currency and desires to "lock in" the U.S. dollar price of that security.

ILLIQUID SECURITIES
We may not invest more than 15% of the market value of the Fund's net assets in
securities  which are illiquid.  Illiquid  securities are those securities that
cannot be disposed of in the ordinary  course of business in seven days or less
at approximately  the value at which the Fund has valued the securities.  

MONEY MARKET INSTRUMENTS
   
We may hold a  certain  portion  of the  Fund's  assets  in  high-quality,  U.S.
dollar-denominated debt securities that have remaining maturities of one year or
less. Such securities may include U.S. Government obligations,  commercial paper
and other short-term corporate obligations, repurchase agreements collateralized
with U.S. Government securities,  certificates of deposit, bankers' acceptances,
bank deposits, and other financial institution obligations. These securities may
carry fixed or variable interest rates.

You also can find the most current price of your shares in the business section
of your newspaper in the mutual fund section under the heading "USAA Group" and
the symbol "Grwth."

You may see the Fund's total return quoted in advertisements  and reports.  All
mutual funds must use the same formula to calculate total return.  Total return
measures the price change in a share assuming the  reinvestment of all dividend
income and capital gain  distributions.  You may also see a  comparison  of the
Fund's  performance  to that of other  mutual  funds  with  similar  investment
objectives and to stock or relevant indexes.

For the following  periods ended  September 30, 1997, the Fund's average annual
total returns have been:
   
               1 Year................................   34.93%
               5 Years...............................   18.50%
              10 Years...............................   12.42%
    
Figures  on page 5 are  different  because  they are for  periods  which  ended
December 31, 1996.

WILL THE VALUE OF YOUR INVESTMENT FLUCTUATE?  
   
Yes, it will. The value of your investment could increase or decrease.  The bar
chart and table shown on the next page  illustrate  the Fund's  volatility  and
performance  from year to year over the past ten years and shows how the Fund's
average annual returns for the one-,  five-,  and ten-year  periods  compare to
those of a broad-based  securities  market index.  Again,  remember  historical
performance might not be repeated in the future.

A WORD ABOUT RISK

Portions of this Prospectus  describe the risks you will face as an investor in
the  Fund.  Keep in mind that  generally  investments  with a higher  potential
reward also have a higher risk of losing money.  The reverse is also  generally
true:  the lower the risk,  the lower the  potential  reward.  However,  as you
consider an  investment  in the Fund,  you should also take into  account  your
tolerance for the daily  fluctuations of the financial  markets and whether you
can afford to leave your money in this  investment  for long periods of time to
ride out down periods.  

[CAUTION LIGHT GRAPHIC]
Look for this symbol  throughout  the  Prospectus.  We use it to mark  detailed
information about the main risks that you will face as a Fund shareholder.

FUND INVESTMENTS

Investment Policies and Risks

Q       What is the Fund's investment policy?

A       We will  invest  the Fund's  assets  primarily  in common  stocks or in
        securities that are convertible  into common stocks.  However,  we will
        limit the Fund's  investment  in  convertible  securities  to 5% of the
        value of the  Fund's  net  assets  at the  time  these  securities  are
        purchased.  We may also invest the Fund's  assets in warrants,  rights,
        real estate investment  trusts,  and in nonconvertible  debt securities
        when  we  believe  these  securities  will  offer a good  prospect  for
        appreciation.
   
        As a  temporary  defensive  measure,  we may  invest  up to 100% of the
        Fund's assets in high-quality, short-term debt instruments.
    
[CAUTION LIGHT GRAPHIC]  
MARKET RISK. Because this Fund invests in equity  securities,  it is subject to
market risk. Stock  prices in general may decline  over short or even  extended
periods,  regardless  of the  success  or failure  of an  individual  company's
operations.  The stock market  tends to run in cycles,  with periods when stock
prices generally go up and periods when stock prices generally go down.  Stocks
tend to go up and down more than bonds.

Q       How will particular securities be selected? 

A       Generally,  we will invest the Fund's  assets in stocks that are deemed
        to be out of favor or undervalued. These investments will have at least
        one of the following  characteristics: 

        o  a recent significant market price decline;
        o  sustained poor performance relative to the market or their industry;
        o  extremely pessimistic appraisal by most investors; or
        o  a market price that is  low relative to earnings, cash flow, assets,
           or book  value. 

        We will not trade the Fund's securities  to realize short-term profits;
        but rather,  we intend  to purchase  securities for long-term  capital
        appreciation.

                                       6
<PAGE>

Q       May the Fund's assets be invested in securities of foreign issuers?

A       Yes.  We may invest up to 30% of the Fund's  total  assets in  American
        Depositary  Receipts  (ADRs) or similar forms of ownership  interest in
        securities  of  foreign  issuers  deposited  with  a  depositary,   and
        securities  of  foreign  issuers  that are  traded  on U.S.  securities
        exchanges or in U.S. over-the-counter markets.

[CAUTION LIGHT GRAPHIC] 
FOREIGN  INVESTING.  Investing in  securities  of foreign  issuers poses unique
risks:  currency  exchange  rate  fluctuations;   increased  price  volatility;
different accounting,  reporting, and disclosure requirements; and political or
social instability. In the past, equity and debt instruments of foreign issuers
have been more volatile than equity and debt instruments of U.S. issuers.
   
For additional  information  about other  securities in which we may invest the
Fund's assets, see APPENDIX A on page 17.
    
Investment Restrictions

The following restrictions may only be changed with shareholder approval: 

o    The Fund may not invest more than 25% of its total assets in one industry.

o    The Fund may not invest more than 5% of its total assets in any one issuer
     or own  more  than 10% of the  outstanding  voting  securities  of any one
     issuer. This limitation does not apply to U.S. Government securities,  and
     only applies to 75% of the Fund's total assets. 

o    The Fund may borrow only for temporary or emergency  purposes in an amount
     not exceeding 33 1/3% of its total assets. 

You will find a complete listing of the precise investment  restrictions in the
Fund's Statement for Additional Information.

USING MUTUAL FUNDS IN 
AN INVESTMENT PROGRAM

I. The Idea Behind Mutual Funds

Mutual funds provide small investors some of the advantages  enjoyed by wealthy
investors.  A  relatively  small  investment  can  buy  part  of a  diversified
portfolio. That portfolio is managed by investment professionals, relieving you
of the  need to make  individual  stock  or bond  selections.  You  also  enjoy
conveniences, such as daily pricing, liquidity, and in the

                                       8
<PAGE>

case of the USAA Family of Funds,  no sales charge.  The portfolio,  because of
its size, has lower transaction costs on its trades than most individuals would
have. As a result,  you own an investment that in earlier times would have been
available only to very wealthy people.

II. Using Funds in an Investment Program

In  choosing a mutual  fund as an  investment  vehicle,  you are giving up some
investment decisions,  but must still make others. The decisions you don't have
to make are those involved with choosing individual securities. We will perform
that function.  In addition, we will arrange for the safekeeping of securities,
auditing the annual financial  statements,  and daily valuation of the Fund, as
well as other functions.   

You,  however,  retain  at  least  part of the  responsibility  for an  equally
important  decision.  This decision involves  determining a portfolio of mutual
funds that balances your  investment  goals with your tolerance for risk. It is
likely that this decision may include the use of more than one fund of the USAA
Family of Funds.  

For  example,  assume you wish to invest in  awidely-diversified,  common stock
portfolio.  You could combine an investment in the Growth Fund with investments
in other  mutual funds that invest in stocks of large and small  companies  and
high-dividend  stocks.  This is just one way you could  combine  funds that fit
your own risk and reward goals.

III. USAA's Family of Funds
   
We offer you another  alternative for asset  allocation with our asset strategy
funds  listed on page 18. These unique  mutual funds  provide a  professionally
managed  diversified  investment  portfolio  within  a  mutual  fund.  They are
designed  for the  individual  who  prefers to  delegate  the asset  allocation
process to an investment manager and are structured to achieve  diversification
across a number of investment categories. 
    
Whether you prefer to create  your own mix of mutual  funds or use a USAA Asset
Strategy  Fund,  the USAA  Family of Funds  provides  a broad  range of choices
covering  just  about  any   investor's   investment   objectives.   Our  sales
representatives  stand  ready to assist you with your  choices  and to help you
craft a portfolio which meets your needs.

HOW TO INVEST

Purchase of Shares

OPENING AN ACCOUNT
   
You may open an account and make an investment  as described  below by mail, in
person,  bank wire,  electronic  funds  transfer  (EFT),  or phone. A complete,
signed application is required for each new account.
                                       
                                       9
<PAGE>
    
TAX ID NUMBER  
Each shareholder  named on the account must provide a social security number or
tax identification number to avoid possible withholding requirements. 

EFFECTIVE DATE
When you make a purchase,  your purchase price will be the net asset value(NAV)
per share next  determined  after we  receive  your  request in proper  form as
described  below.  The Fund's  NAV is  determined  at the close of the  regular
trading  session  (generally  4:00  p.m.  Eastern  Time) of the New York  Stock
Exchange  (NYSE) each day the NYSE is open. If we receive your request prior to
that time,  your purchase  price will be the NAV per share  determined for that
day. If we receive  your  request  after the NAV per share is  calculated,  the
purchase  will be effective on the next  business  day. If you plan to purchase
Fund shares with a foreign check,  we suggest you convert your foreign check to
U.S.  dollars prior to investment in the Fund to avoid a potential delay in the
effective date of your purchase of up to four to six weeks. Furthermore, a bank
charge may be assessed in the clearing process, which will be deducted from the
amount of the purchase.  

MINIMUM INVESTMENTS

Redemption of Shares

You may redeem Fund shares by any of the methods described below on any day the

are received in a manner as  described  below.  However,  if  instructions  are
received  after  the NAV per share  calculation  (generally  4:00 p.m.  Eastern
Time), redemption will be effective on the next business day.

Within seven days after the effective date of redemption, we will send you your
money. Payment for redemption of shares purchased by EFT or check is sent after
the EFT or check has cleared,  which could take up to 15 days from the purchase
date. If you are considering  redeeming shares soon after purchase,  you should
purchase by bank wire or certified check to avoid delay.

In  addition,  the  Company may elect to suspend  the  redemption  of shares or
postpone the date of payment in limited circumstances.

IMPORTANT INFORMATION ABOUT PURCHASES AND REDEMPTIONS

Investor's Guide to USAA Mutual Fund Services 

Upon your initial  investment with us, you will receive the INVESTOR'S GUIDE to
help you get the most out of your USAA mutual  fund  account and to help you in
your role as an investor.  In the INVESTOR'S  GUIDE,  you will find  additional
information on purchases,  redemptions,  and methods of payment.  You will also
find in-depth information on automatic investment plans, shareholder statements
and reports, and other useful information.

Account Balance

Beginning in September  1998,  and occurring each  September  thereafter,  USAA
Shareholder  Account Services (SAS),  the Fund's transfer agent,  will assess a
small balance account fee of $12 to each shareholder account with a balance, at
the time of assessment, of less than $2,000. The fee will reduce total transfer
agency fees paid by the Fund to SAS. Accounts exempt from the fee include:  (1)
any  account  regularly  purchasing  additional  shares  each month  through an
automatic investment plan; (2) any account registered under the  

                                      12
<PAGE>

Uniform  Gifts/Transfers  to Minors Act  (UGMA/UTMA);  (3) all (non-IRA)  money
market fund accounts;  (4) any account whose  registered owner has an aggregate
balance of $50,000  or more  invested  in USAA  mutual  funds;  and (5) all IRA
accounts (for the first year the account is open).

Company Rights

The Company reserves the right to:

o    reject  purchase  or  exchange  orders  when in the best  interest  of the
     Company; 

o    limit or  discontinue  the  offering  of  shares of any  portfolio  of the
     Company without notice to the shareholders;

o    impose a  redemption  charge of up to 1% of the net asset  value of shares
     redeemed  if  circumstances   indicate  a  charge  is  necessary  for  the
     protection of remaining investors (for example, if excessive market-timing
     share activity unfairly burdens  long-term  investors);  however,  this 1%
     charge will not be imposed  upon  shareholders  unless  authorized  by the
     Board of Directors and the required notice has been given to shareholders;
     
o    require a signature  guarantee for purchases,  redemptions,  or changes in
     account  information in those  instances  where the  appropriateness  of a
     signature  authorization  is in  question.  The  Statement  of  Additional
     Information contains information on acceptable guarantors;

o    redeem an account with less than 10 shares, with certain limitations.

EXCHANGES

Exchange Privilege

The exchange privilege is automatic when you complete your application. You may
exchange  shares  among Funds in the USAA Family of Funds,  provided you do not
hold these shares in stock  certificate  form and the shares to be acquired are
offered  in  your  state  of  residence.   The  Fund's   transfer   agent  will
simultaneously  process exchange  redemptions and purchases at the share prices
next  determined  after the exchange order is received.  For federal income tax
purposes,  an exchange  between Funds is a taxable event;  and as such, you may
realize a capital  gain or loss.  
   
The  Fund has undertaken certain procedures regarding telephone transactions as
described on page 12.

Exchange Limitations, Excessive Trading
   
To  minimize  Fund costs and to protect the Funds and their  shareholders  from
unfair expense burdens,  the Funds restrict excessive  exchanges.  The limit on
exchanges  out of any Fund in the USAA Family of Funds for each  account is six
per calendar  year (except  there is no  limitation on exchanges out of the Tax
Exempt Short-Term Fund,  Short-Term Bond Fund, or any of the money market funds
in the USAA Family of Funds). 
    
SHAREHOLDER INFORMATION

Share Price Calculation

The price at which shareholders purchase and redeem Fund shares is equal to the
net asset  value  (NAV)  per  share  determined  on the  effective  date of the
purchase or  redemption.  You may buy and sell Fund shares at the NAV per share
without a sales charge.

When

The  Fund's NAV per share is  calculated  at the close of the  regular  trading
session of the NYSE, which is usually 4:00 p.m. Eastern Time.

How

The NAV per share is calculated by adding the value of all securities and other
assets in the Fund, deducting liabilities, and dividing by the number of shares
outstanding.

Dividends and Distributions

The Fund pays net  investment  income  dividends  yearly.  Any net capital gain
distribution  usually  occurs  within 45 days of the July 31  fiscal  year end,
which would be  somewhere  around the middle of  September.  The Fund will make
additional payments to shareholders,  if necessary,  to avoid the imposition of
any federal income or excise tax.

All  income  dividends  and  capital  gain   distributions   are  automatically
reinvested,  unless we receive different instructions from you. The share price
will be the NAV of the Fund shares computed on the ex-dividend date. Any income
dividends  or capital gain  distributions  paid by the Fund will reduce the NAV
per share by the amount of the dividend or  distribution.  These  dividends and
distributions are subject to taxes.

We will invest any  dividend  or  distribution  payment  returned to us in your
account at the  then-current NAV per share.  Dividend and  distribution  checks
become  void six months  from the date on the  check.  The amount of the voided
check will be invested in your account at the then-current NAV per share.

Federal Taxes

This tax  information  is quite  general and refers to the  federal  income tax
provisions in effect as of the date of this Prospectus.  Note that the recently
enacted Taxpayer Relief Act of 1997 and regulations that will likely be created
to  implement   the  Act  may  affect  the  status  and  treatment  of  certain
distributions  shareholders  receive from the Fund. We urge you to consult your
own tax  adviser  about the status of  distributions  from the Fund in your own
state and locality.

FUND - The Fund  intends to qualify as a  regulated  investment  company  (RIC)
under Subchapter M of the Internal Revenue Code of 1986, as amended.  As a RIC,
the Fund will not be subject to federal income tax on its net investment income
and net capital gains distributed to shareholders.  Net capital gains are those
gains in excess of capital losses.

SHAREHOLDER - Dividends from taxable net investment income and distributions of
net short-term  capital gains are taxable to shareholders  as ordinary  income,
whether received in cash or reinvested in additional shares. A portion of these
dividends may qualify for the 70%  dividends  received  deduction  available to
corporations.

Regardless  of the length of time you have held the Fund shares,  distributions
of net long-term  capital gains are taxable as long-term  capital gains whether
received in cash or reinvested in additional shares.

Redemptions  and  exchanges  are subject to income tax based on the  difference
between  the  cost of  shares  when  purchased  and  the  price  received  upon
redemption or exchange.

WITHHOLDING  - Federal law  requires the Fund to withhold and remit to the U.S.
Treasury a portion of the income dividends and capital gain  distributions  and
proceeds of redemptions paid to any non-corporate shareholder who:

o    fails to furnish the Fund with a correct tax identification number,  
o    underreports dividend or interest income, or 
o    fails to certify that he or she is not subject to withholding. 

To avoid this withholding requirement, you must certify on your application, or
on a separate  Form W-9 supplied by the Fund's  transfer  agent,  that your tax
identification  number is correct and you are not  currently  subject to backup
withholding.

REPORTING - The Fund will report annually to you information concerning the tax
status of dividends and distributions for federal income tax purposes.

                                      15

DESCRIPTION OF SHARES 

The Fund is a series of USAA Mutual Fund,  Inc.  (Company) and is  diversified.
The Company is an open-end management investment company incorporated under the
laws of the State of  Maryland.  The Company is  authorized  to issue shares of
common  stock of separate  series,  each of which is commonly  referred to as a
mutual fund. There are ten mutual funds in the Company, including this Fund.
   
The Company does not hold annual or regular  meetings of shareholders and holds
special  meetings only as required by the  Investment  Company Act of 1940. The
Directors  may fill  vacancies  on the Board or appoint  new  Directors  if the
result is that at least  two-thirds of the Directors have still been elected by
shareholders.  Shareholders have one vote per share (with proportionate  voting
for  fractional  shares)  regardless  of the  relative  net asset  value of the
shares. If a matter affects an individual fund in the Company,  there will be a
separate  vote  of  the  shareholders  of  that  specific  fund.   Shareholders
collectively  holding at least 10% of the outstanding shares of the Company may
request a  shareholder  meeting at any time for the purpose of voting to remove
one or more of the Directors. The Company will assist in communicating to other
shareholders about the meeting.

                                   APPENDIX A

THE FOLLOWING ARE DESCRIPTIONS OF CERTAIN TYPES OF SECURITIES IN WHICH WE MAY
INVEST THE FUND'S ASSETS: 

CONVERTIBLE  SECURITIES  
   
We may invest in convertible securities, which are bonds, preferred stocks, and
other  securities that pay interest or dividends and offer the buyer the option
of  converting  the  security  into  common  stock.  The  value of  convertible
securities depends partially on interest rate changes and the credit quality of
the issuer. Because a convertible security affords an investor the opportunity,
through its conversion feature,  to participate in the capital  appreciation of
the underlying  common stock, the value of convertible  securities also depends
on the price of the underlying common stock.
    
ILLIQUID SECURITIES
We may not invest more than 15% of the market value of the Fund's net assets in
securities  which are illiquid.  Illiquid  securities are those securities that
cannot be disposed of in the ordinary  course of business in seven days or less
at approximately the value at which the Fund has valued the securities.

MONEY MARKET INSTRUMENTS  
   
We may hold a  certain  portion  of the  Fund's  assets in  high-quality,  U.S.
dollar-denominated  debt securities that have remaining  maturities of one year
or less. Such securities may include U.S.  Government  obligations,  commercial
paper  and  other  short-term  corporate  obligations,   repurchase  agreements
collateralized  with  U.S.  Government  securities,  certificates  of  deposit,
bankers'   acceptances,   bank  deposits,   and  other  financial   institution
obligations. These securities may carry fixed or variable interest rates.

You also can find the most current price of your shares in the business section
of your newspaper in the mutual fund section under the heading "USAA Group" and
the symbol "Gr&Inc."

You may see the Fund's total return quoted in advertisements  and reports.  All
mutual funds must use the same formula to calculate total return.  Total return
measures the price change in a share assuming the  reinvestment of all dividend
income and capital gain  distributions.  You may also see a  comparison  of the
Fund's  performance  to that of other  mutual  funds  with  similar  investment
objectives and to stock or relevant indexes.

For the following  periods ended  September 30, 1997, the Fund's average annual
total returns have been:
   
              1 Year..................................  37.04%
              Since Inception on June 1, 1993.........  19.40%
    
Figures  on page 5 are  different  because  they are for  periods  which  ended
December 31, 1996.

WILL THE VALUE OF YOUR INVESTMENT FLUCTUATE?  
   
Yes, it will. The value of your investment could increase or decrease.  The bar
chart and table shown on the next page  illustrate  the Fund's  volatility  and
performance  from  year to year  over the life of the  Fund and  shows  how the
Fund's  average annual returns for one year and the life of the Fund compare to
those of a broad-based  securities  market index.  Again,  remember  historical
performance might not be repeated in the future.

A WORD ABOUT RISK
   
Portions of this Prospectus  describe the risks you will face as an investor in
the  Fund.  Keep in mind that  generally  investments  with a higher  potential
reward also have a higher risk of losing money.  The reverse is also  generally
true:  the lower the risk,  the lower the  potential  reward.  However,  as you
consider an  investment  in the Fund,  you should also take into  account  your
tolerance for the daily  fluctuations of the financial  markets and whether you
can afford to leave your money in this  investment  for long periods of time to
ride out down periods.  
    
[CAUTION LIGHT GRAPHIC]
Look for this symbol  throughout  the  Prospectus.  We use it to mark  detailed
information about the main risks that you will face as a Fund shareholder.

FUND INVESTMENTS

Investment Policies and Risks

   Q    What is the Fund's investment policy?

   
   A    We will invest the Fund's  assets  primarily in dividend  paying equity
        securities.  We use the term  "equity  securities"  to  include  common
        stocks,  securities  convertible  into common stocks,  securities which
        carry the right to buy common stocks, and real estate investment trusts
        (REITs). We will limit the Fund's investment in convertible  securities
        to 5% of  the  value  of the  Fund's  net  assets  at  the  time  these
        securities are  purchased.  We may also invest in  nonconvertible  debt
        securities and nonconvertible preferred stock. 

        As a temporary defensive measure,we may invest up to 100% of the Fund's
        assets in high-quality, short-term debt instruments.
    
[CAUTION LIGHT GRAPHIC]  
MARKET RISK. Because this Fund invests in equity  securities,  it is subject to
market risk.  Stock  prices in general may decline over short or even  extended
periods,  regardless  of the  success  or failure  of an  individual  company's
operations.  The stock market  tends to run in cycles,  with periods when stock
prices generally go up and periods when stock prices generally go down.  Equity
securities tend to go up and down more than bonds.

[CAUTION LIGHT GRAPHIC] 
REITS.  Investing  in REITs  may  subject  the  Fund to many of the same  risks
associated with the direct  ownership of real estate.  REITs are dependent upon
the capabilities of the REIT manager(s) and have limited diversification.
         
   Q    May the Fund's assets be invested in securities of foreign issuers?

   A    Yes.  We may invest up to 30% of the Fund's  total  assets in  American
        Depositary  Receipts  (ADRs) or similar forms of ownership  interest in
        securities  of  foreign  issuers  deposited  with  a  depositary,   and
        securities  of  foreign  issuers  that are  traded  on U.S.  securities
        exchanges or in U.S. over-the-counter markets.

[CAUTION LIGHT GRAPHIC]
FOREIGN  INVESTING.  Investing in  securities  of foreign  issuers poses unique
risks:  currency  exchange  rate  fluctuations;   increased  price  volatility;
different accounting,  reporting, and disclosure requirements; and political or
social instability. In the past, equity and debt instruments of foreign issuers
have been more volatile than equity and debt instruments of U.S. issuers.

For additional  information  about other investments in which we may invest the
Fund's assets, see APPENDIX A on page 17.
    
Investment Restrictions

The following restrictions may only be changed with shareholder approval: 

o    The Fund may not invest more than 25% of its total assets in one industry.

o    The Fund may not invest more than 5% of its total assets in any one issuer
     or own  more  than 10% of the  outstanding  voting  securities  of any one
     issuer. This limitation does not apply to U.S. Government securities,  and
     only applies to 75% of the Fund's total assets. 

o    The Fund may borrow only for temporary or emergency  purposes in an amount
     not exceeding 33 1/3% of its total assets. 

You will find a complete listing of the precise investment  restrictions in the
Fund's Statement of Additional Information.

supervision  by the Board of Directors.  For our services,  the Fund pays us an
annual  fee.  This fee was  computed  and paid at  three-fifths  of one percent
(.60%) of average net assets for the fiscal year ended July 31, 1997.

We also provide  services  related to selling the Fund's  shares and receive no
compensation for those services.

engage  in  personal  securities  transactions,  they  are  restricted  by  the

USING MUTUAL FUNDS IN AN
INVESTMENT PROGRAM

I. The Idea Behind Mutual Funds

Mutual funds provide small investors some of the advantages  enjoyed by wealthy
investors.  A  relatively  small  investment  can  buy  part  of a  diversified
portfolio. That portfolio is managed by investment professionals, relieving you
of the  need to make  individual  stock  or bond  selections.  You  also  enjoy
conveniences,  such as daily  pricing,  liquidity,  and in the case of the USAA
Family of Funds, no sales charge. The portfolio, because of its size, has lower
transaction  costs on its trades than most individuals would have. As a result,
you own an investment  that in earlier times would have been  available only to
very wealthy people.

II. Using Funds in an Investment Program

In  choosing a mutual  fund as an  investment  vehicle,  you are giving up some
investment decisions,  but must still make others. The decisions you don't have
to make are those involved with choosing individual securities. We will perform
that function.  In addition, we will arrange for the safekeeping of securities,
auditing the annual financial  statements,  and daily valuation of the Fund, as
well as other functions.

                                       8
<PAGE>

You,  however,  retain  at  least  part of the  responsibility  for an  equally
important  decision.  This decision involves  determining a portfolio of mutual
funds that balances your  investment  goals with your tolerance for risk. It is
likely that this decision may include the use of more than one fund of the USAA
Family of Funds.

For example,  assume you wish to invest in a  widely-diversified,  common stock
portfolio.  You could  combine an  investment  in the Growth & Income Fund with
investments in other mutual funds that primarily seek capital  appreciation  by
investing  in stocks of large  and  small  companies.  This is just one way you
could combine funds that fit your own risk and reward goals.

III. USAA's Family of Funds
   
We offer you another  alternative for asset  allocation with our asset strategy
funds  listed on page 18. These unique  mutual funds  provide a  professionally
managed  diversified  investment  portfolio  within  a  mutual  fund.  They are
designed  for the  individual  who  prefers to  delegate  the asset  allocation
process to an investment manager and are structured to achieve  diversification
across a number of investment categories. 
    
Whether you prefer to create  your own mix of mutual  funds or use a USAA Asset
Strategy  Fund,  the USAA  Family of Funds  provides  a broad  range of choices
covering  just  about  any   investor's   investment   objectives.   Our  sales
representatives  stand  ready to assist you with your  choices  and to help you
craft a portfolio which meets your needs.

HOW TO INVEST

Purchase of Shares

OPENING AN ACCOUNT
   
You may open an account and make an investment  as described  below by mail, in
person,  bank wire,  electronic  funds  transfer  (EFT),  or phone. A complete,
signed application is required for each new account.
    
TAX ID NUMBER  
Each shareholder  named on the account must provide a social security number or
tax identification number to avoid possible withholding requirements.

EFFECTIVE DATE 
When you make a purchase, your purchase price will be the net asset value (NAV)
per share next  determined  after we  receive  your  request in proper  form as
described  below.  The Fund's  NAV is  determined  at the close of the  regular
trading session (generally

                                       9
<PAGE>

4:00 p.m. Eastern Time) of the New York Stock Exchange (NYSE) each day the NYSE
is open.  If we receive your request prior to that time,  your  purchase  price
will be the NAV per share  determined  for that day. If we receive your request
after the NAV per share is  calculated,  the purchase  will be effective on the
next business day. If you plan to purchase Fund shares with a foreign check, we
suggest you convert your foreign  check to U.S.  dollars prior to investment in
the Fund to avoid a potential  delay in the effective  date of your purchase of
up to four to six weeks.  Furthermore,  a bank  charge may be  assessed  in the
clearing process, which will be deducted from the amount of the purchase.

MINIMUM INVESTMENTS  

INITIAL PURCHASE 
[MONEY GRAPHIC]      o $3,000  [$500  Uniform  Gifts/Transfers  to  Minors  Act
                       (UGMA/UTMA)  accounts  and $250 for IRAs] or no  initial

                       investments  of at least $50 each.  We may  periodically
                       offer  programs  that  reduce the  minimum  amounts  for
                       monthly  electronic  investments.  Employees of USAA and
                       its  affiliated  companies  may open an account  through
                       payroll  deduction  for as little as $25 per pay  period
                       with no initial investment.

Redemption of Shares

You may redeem Fund shares by any of the methods described below on any day the
NAV per share is calculated.  Redemptions are effective on the day instructions
are received in a manner as  described  below.  However,  if  instructions  are
received  after  the NAV per share  calculation  (generally  4:00 p.m.  Eastern
Time), redemption will be effective on the next business day. 

Within seven days after the effective date of redemption, we will send you your
money. Payment for redemption of shares purchased by EFT or check is sent after
the EFT or check has cleared,  which could take up to 15 days from the purchase
date. If you are considering  redeeming shares soon after purchase,  you should
purchase by bank wire or certified check to avoid delay.

In  addition,  the  Company may elect to suspend  the  redemption  of shares or
postpone the date of payment in limited circumstances.

IMPORTANT INFORMATION ABOUT PURCHASES AND REDEMPTIONS

Investor's Guide to USAA Mutual Fund Services

Upon your initial  investment with us, you will receive the INVESTOR'S GUIDE to
help you get the most out of your USAA mutual  fund  account and to help you in
your role as an investor.  In the INVESTOR'S  GUIDE,  you will find  additional
information on purchases,  redemptions,  and methods of payment.  You will also
find in-depth information on automatic investment plans, shareholder statements
and reports, and other useful information.

Account Balance

Beginning in September  1998,  and occurring each  September  thereafter,  USAA
Shareholder  Account Services (SAS),  the Fund's transfer agent,  will assess a
small balance account fee of $12 to each shareholder account with a balance, at
the time of assessment, of less than $2,000. The fee will reduce total transfer
agency fees paid by the Fund to SAS. Accounts exempt from the fee include:  (1)
any  account  regularly  purchasing  additional  shares  each month  through an
automatic  investment  plan;  (2) any  account  registered  under  the  Uniform
Gifts/Transfers to Minors Act (UGMA/UTMA); (3) all (non-IRA) money market

                                      12
<PAGE>

fund accounts;  (4) any account whose registered owner has an aggregate balance
of $50,000 or more invested in USAA mutual funds; and (5) all IRA accounts (for
the first year the account is open).

Company Rights 

The Company reserves the right to:

o    reject  purchase  or  exchange  orders  when in the best  interest  of the
     Company; 

o    limit or  discontinue  the  offering  of  shares of any  portfolio  of the
     Company without notice to the shareholders;

o    impose a  redemption  charge of up to 1% of the net asset  value of shares
     redeemed  if  circumstances   indicate  a  charge  is  necessary  for  the
     protection of remaining investors (for example, if excessive market-timing
     share activity unfairly burdens  long-term  investors);  however,  this 1%
     charge will not be imposed  upon  shareholders  unless  authorized  by the
     Board of Directors and the required notice has been given to shareholders;
     
o    require a signature  guarantee for purchases,  redemptions,  or changes in
     account  information in those  instances  where the  appropriateness  of a
     signature  authorization  is in  question.  The  Statement  of  Additional
     Information contains information on acceptable guarantors;

o    redeem an account with less than 10 shares, with certain limitations.

EXCHANGES

Exchange Privilege

The exchange privilege is automatic when you complete your application. You may
exchange  shares  among Funds in the USAA Family of Funds,  provided you do not
hold these shares in stock  certificate  form and the shares to be acquired are
offered  in  your  state  of  residence.   The  Fund's   transfer   agent  will
simultaneously  process exchange  redemptions and purchases at the share prices
next  determined  after the exchange order is received.  For federal income tax
purposes,  an exchange  between Funds is a taxable event;  and as such, you may
realize a capital  gain or loss.  
   
The  Fund has undertaken certain procedures regarding telephone transactions as
described on page 12.

Exchange Limitations, Excessive Trading
   
To  minimize  Fund costs and to protect the Funds and their  shareholders  from
unfair expense burdens,  the Funds restrict excessive  exchanges.  The limit on
exchanges  out of any Fund in the USAA Family of Funds for each  account is six
per calendar  year (except  there is no  limitation on exchanges out of the Tax
Exempt Short-Term Fund,  Short-Term Bond Fund, or any of the money market funds
in the USAA Family of Funds). 
    
SHAREHOLDER INFORMATION

Share Price Calculation

The price at which shareholders purchase and redeem Fund shares is equal to the
net asset  value  (NAV)  per  share  determined  on the  effective  date of the
purchase or  redemption.  You may buy and sell Fund shares at the NAV per share
without a sales charge.

When

The  Fund's NAV per share is  calculated  at the close of the  regular  trading
session of the NYSE, which is usually 4:00 p.m. Eastern Time.

How

The NAV per share is calculated by adding the value of all securities and other
assets in the Fund, deducting liabilities, and dividing by the number of shares
outstanding.

Dividends and Distributions

The Fund pays net investment income dividends  quarterly.  Any net capital gain
distribution  usually  occurs  within 45 days of the July 31  fiscal  year end,
which would be  somewhere  around the middle of  September.  The Fund will make
additional payments to shareholders,  if necessary,  to avoid the imposition of
any federal income or excise tax.

All  income  dividends  and  capital  gain   distributions   are  automatically
reinvested,  unless we receive different instructions from you. The share price
will be the NAV of the Fund shares computed on the ex-dividend date. Any income
dividends  or capital gain  distributions  paid by the Fund will reduce the NAV
per share by the amount of the dividend or  distribution.  These  dividends and
distributions are subject to taxes.

We will invest any  dividend  or  distribution  payment  returned to us in your
account at the  then-current NAV per share.  Dividend and  distribution  checks
become  void six months  from the date on the  check.  The amount of the voided
check will be invested in your account at the then-current NAV per share.

                                      14

Federal Taxes

This tax  information  is quite  general and refers to the  federal  income tax
provisions in effect as of the date of this Prospectus.  Note that the recently
enacted Taxpayer Relief Act of 1997 and regulations that will likely be created
to  implement   the  Act  may  affect  the  status  and  treatment  of  certain
distributions  shareholders  receive from the Fund. We urge you to consult your
own tax  adviser  about the status of  distributions  from the Fund in your own
state and locality.

FUND - The Fund  intends to qualify as a  regulated  investment  company  (RIC)
under Subchapter M of the Internal Revenue Code of 1986, as amended.  As a RIC,
the Fund will not be subject to federal income tax on its net investment income
and net capital gains distributed to shareholders.  Net capital gains are those
gains in excess of capital losses.  

SHAREHOLDER - Dividends from taxable net investment income and distributions of
net short-term  capital gains are taxable to shareholders  as ordinary  income,
whether received in cash or reinvested in additional shares. A portion of these
dividends may qualify for the 70%  dividends  received  deduction  available to
corporations.  

Regardless  of the length of time you have held the Fund shares,  distributions
of net long-term  capital gains are taxable as long-term  capital gains whether
received in cash or reinvested in additional shares.  

Redemptions  and  exchanges  are subject to income tax based on the  difference
between  the  cost of  shares  when  purchased  and  the  price  received  upon
redemption or exchange. 

WITHHOLDING - Federal law  requires the Fund to withhold  and remit to the U.S.
Treasury a portion of the income dividends and capital gain  distributions  and
proceeds of redemptions paid to any non-corporate shareholder who:

o    fails to furnish the Fund with a correct tax identification number,
o    underreports dividend or interest income, or
o    fails to certify that he or she is not subject to withholding.

To avoid this withholding requirement, you must certify on your application, or
on a separate  Form W-9 supplied by the Fund's  transfer  agent,  that your tax
identification  number is correct and you are not  currently  subject to backup
withholding.

REPORTING - The Fund will report annually to you information concerning the tax
status of dividends and distributions for federal income tax purposes.

                                      15

DESCRIPTION OF SHARES 

The Fund is a series of USAA Mutual Fund,  Inc.  (Company) and is  diversified.
The Company is an open-end management investment company incorporated under the
laws of the State of  Maryland.  The Company is  authorized  to issue shares of
common  stock of separate  series,  each of which is commonly  referred to as a
mutual fund. There are ten mutual funds in the Company, including this Fund.
   
The Company does not hold annual or regular  meetings of shareholders and holds
special  meetings only as required by the  Investment  Company Act of 1940. The
Directors  may fill  vacancies  on the Board or appoint  new  Directors  if the
result is that at least  two-thirds of the Directors have still been elected by
shareholders.  Shareholders have one vote per share (with proportionate  voting
for  fractional  shares)  regardless  of the  relative  net asset  value of the
shares. If a matter affects an individual fund in the Company,  there will be a
separate  vote  of  the  shareholders  of  that  specific  fund.   Shareholders
collectively  holding at least 10% of the outstanding shares of the Company may
request a  shareholder  meeting at any time for the purpose of voting to remove
one or more of the Directors. The Company will assist in communicating to other
shareholders about the meeting.

                                   APPENDIX A

THE FOLLOWING ARE DESCRIPTIONS OF CERTAIN TYPES OF SECURITIES IN WHICH WE MAY
INVEST THE FUND'S ASSETS:  

CONVERTIBLE  SECURITIES  
   
We may invest in convertible securities, which are bonds, preferred stocks, and
other  securities that pay interest or dividends and offer the buyer the option
of  converting  the  security  into  common  stock.  The  value of  convertible
securities depends partially on interest rate changes and the credit quality of
the issuer. Because a convertible security affords an investor the opportunity,
through its conversion feature,  to participate in the capital  appreciation of
the underlying  common stock, the value of convertible  securities also depends
on the price of the underlying common stock.
    
ILLIQUID SECURITIES 
We may not invest more than 15% of the market value of the Fund's net assets in
securities  which are illiquid.  Illiquid  securities are those securities that
cannot be disposed of in the ordinary  course of business in seven days or less
at approximately the value at which the Fund has valued the securities.

MONEY MARKET INSTRUMENTS  
   
We may hold a  certain  portion  of the  Fund's  assets in  high-quality,  U.S.
dollar-denominated  debt securities that have remaining  maturities of one year
or less. Such securities may include U.S.  Government  obligations,  commercial
paper  and  other  short-term  corporate  obligations,   repurchase  agreements
collateralized  with  U.S.  Government  securities,  certificates  of  deposit,
bankers'   acceptances,   bank  deposits,   and  other  financial   institution
obligations. These securities may carry fixed or variable interest rates.

You also can find the most current price of your shares in the business section
of your newspaper in the mutual fund section under the heading "USAA Group" and
the symbol "IncStk."
   
You may see the Fund's total return quoted in advertisements  and reports.  All
mutual funds must use the same formula to calculate total return.  Total return
measures the price change in a share assuming the  reinvestment of all dividend
income and capital gain  distributions.  You may also see a  comparison  of the
Fund's  performance  to that of other  mutual  funds  with  similar  investment
objectives and to stock or relevant indexes.
    
For the following  periods ended  September 30, 1997, the Fund's average annual
total returns have been:
   
                  1 Year............................... 31.46%
                  5 Years.............................. 16.04%
                 10 Years.............................. 13.55%
    
Figures  on page 5 are  different  because  they are for  periods  which  ended
December 31, 1996.

WILL THE VALUE OF YOUR INVESTMENT FLUCTUATE?  
   
Yes, it will. The value of your investment could increase or decrease.  The bar
chart and table shown on the next page  illustrate  the Fund's  volatility  and
performance  from  year to year  over the life of the  Fund and  shows  how the
Fund's average  annual returns for the one- and five-year  periods and the life
of the Fund compare to those of a broad-based  securities market index.  Again,
remember historical performance might not be repeated in the future.

A WORD ABOUT RISK
   
Portions of this Prospectus  describe the risks you will face as an investor in
the  Fund.  Keep in mind that  generally  investments  with a higher  potential
reward also have a higher risk of losing money.  The reverse is also  generally
true:  the lower the risk,  the lower the  potential  reward.  However,  as you
consider an  investment  in the Fund,  you should also take into  account  your
tolerance for the daily  fluctuations of the financial  markets and whether you
can afford to leave your money in this  investment  for long periods of time to
ride out down periods.  
    
[CAUTION LIGHT GRAPHIC]
Look for this symbol  throughout  the  Prospectus.  We use it to mark  detailed
information about the main risks that you will face as a Fund shareholder.

FUND INVESTMENTS

Investment Policies and Risks

   Q   What is the Fund's investment policy?

   A   We will invest the Fund's assets  primarily in the equity  securities of
       well-established, large companies with above-average dividend yields and
       in real  estate  investment  trusts  (REITs).  We  attempt  to provide a
       portfolio  with a dividend yield above the average of the S&P 500 Index.
       We use the term "equity securities" to include common stocks,  preferred
       stocks,  securities convertible into common stocks, and securities which
       carry the right to buy common stocks. 
   
       As a temporary defensive measure, we may invest up to 100% of the Fund's
       assets in high-quality, short-term debt instruments.

[CAUTION LIGHT GRAPHIC] 
MARKET  RISK.  Because  this  Fund  invests  in  equity  securities,  including
convertible  securities,  it is subject to market risk. Stock prices in general
may decline over short or even extended  periods,  regardless of the success or
failure of an individual company's operations. The stock market tends to run in
cycles,  with periods when stock prices  generally go up and periods when stock
prices  generally go down.  Equity  securities tend to go up and down more than
bonds.
    
[CAUTION LIGHT GRAPHIC]
REITS.  Investing  in REITs  may  subject  the  Fund to many of the same  risks
associated with the direct  ownership of real estate.  REITs are dependent upon
the capabilities of the REIT manager(s) and have limited diversification.

   Q   What other types of securities will the Fund purchase?

   A   We may also  invest up to 35% of the Fund's  net  assets in  convertible
       preferred  stocks and up to 5% of the  Fund's net assets in  convertible
       debt  securities  measured  at the time a security is  purchased.  These
       convertible securities may be rated below investment grade as determined
       by Moody's Investors Service, Inc. or Standard & Poor's Ratings Group or
       may be unrated.

                                       6
<PAGE>
   
[CAUTION LIGHT GRAPHIC]  
INTEREST  RATE  RISK.  Because  the  value of  convertible  securities  depends
partially  on  interest  rate  changes,  the value of the Fund's  portfolio  is
subject to interest  rate risk.  Interest rate risk is the risk that the market
value of  certain  securities,  such as  convertible  securities  in the Fund's
portfolio,  will decline due to rising interest rates.  Prior to any conversion
into common  stock,  convertible  securities  have the same  interest rate risk
characteristics  as bonds.  Bond  prices  are linked to the  prevailing  market
interest rates. In general,  when interest rates rise, the prices of bonds fall
and when interest rates fall, bond prices generally rise.

[CAUTION LIGHT GRAPHIC]  
CREDIT RISK.  Because the value of convertible  securities depends partially on
the issuer's  credit quality,  the value of the Fund's  portfolio is subject to
credit risk.  Credit risk is the possibility  that an issuer of a security will
fail  to make  timely  payments  of  interest  or  principal.  When  evaluating
potential  investments  for the Fund,  our analysts also assess credit risk and
its impact on the Fund's portfolio. Securities rated below investment grade are
deemed to be speculative  and involve greater risk of default due to changes in
interest rates, economic conditions,  and the issuer's  creditworthiness.  As a
result, their prices tend to go up or down more than higher-quality securities.
During periods of economic downturns or rising interest rates,  issuers of such
securities  may  experience  financial  difficulties  which could  affect their
ability to make timely principal and interest  payments.  The Fund's ability to
timely and accurately value and dispose of lower-quality securities may also be
affected by the absence or periodic discontinuance of liquid trading markets.
    
   Q   May the Fund's assets be invested in securities of foreign issuers?

   A   Yes.  We may invest up to 10% of the  Fund's  total  assets in  American
       Depositary  Receipts  (ADRs) or similar  forms of ownership  interest in
       securities  of  foreign  issuers   deposited  with  a  depositary,   and
       securities  of  foreign  issuers  that  are  traded  on U.S.  securities
       exchanges or in U.S. over-the-counter markets.

[CAUTION LIGHT GRAPHIC]
FOREIGN  INVESTING.  Investing in  securities  of foreign  issuers poses unique
risks:  currency  exchange  rate  fluctuations;   increased  price  volatility;
different accounting,  reporting, and disclosure requirements; and political or
social instability. In the past, equity and debt instruments of foreign issuers
have been more volatile than equity and debt instruments of U.S.  issuers.  
   
For additional  information  about other  securities in which we may invest the
Fund's assets, see APPENDIX A on page 17.
    
                                       7

Investment Restrictions

The following restrictions may only be changed with shareholder approval: 

o    The Fund may not invest more than 25% of its total assets in one industry.

o    The Fund may not invest more than 5% of its total assets in any one issuer
     or own  more  than 10% of the  outstanding  voting  securities  of any one
     issuer. This limitation does not apply to U.S. Government securities,  and
     only applies to 75% of the Fund's total assets.

o    The Fund may borrow only for temporary or emergency  purposes in an amount
     not exceeding 33 1/3% of its total assets.

You will find a complete listing of the precise investment  restrictions in the
Fund's Statement of Additional Information.

supervision  by the Board of Directors.  For our services,  the Fund pays us an
annual fee. This fee was computed and paid at one-half of one percent (.50%) of

We also provide  services  related to selling the Fund's  shares and receive no
compensation for those services.

USING MUTUAL FUNDS IN 
AN INVESTMENT PROGRAM

I. The Idea Behind Mutual Funds

Mutual funds provide small investors some of the advantages  enjoyed by wealthy
investors.  A  relatively  small  investment  can  buy  part  of a  diversified
portfolio. That portfolio is managed by investment professionals, relieving you
of the  need to make  individual  stock  or bond  selections.  You  also  enjoy
conveniences,  such as daily  pricing,  liquidity,  and in the case of the USAA
Family of Funds, no sales charge. The portfolio, because of its size, has lower
transaction  costs on its trades than most individuals would have. As a result,
you own an investment  that in earlier times would have been  available only to
very wealthy people.

II. Using Funds in an Investment Program

In  choosing a mutual  fund as an  investment  vehicle,  you are giving up some
investment decisions,  but must still make others. The decisions you don't have
to make are those involved with choosing individual securities. We will perform
that function.  In addition, we will arrange for the safekeeping of securities,
auditing the annual financial  statements,  and daily valuation of the Fund, as
well as other functions.

You,  however,  retain  at  least  part of the  responsibility  for an  equally
important  decision.  This decision involves  determining a portfolio of mutual
funds that balances your  investment  goals with your tolerance for risk. It is
likely that this decision may include the use of more than one fund of the USAA
Family of Funds.

For example,  assume you wish to invest in a  widely-diversified,  common stock
portfolio.  You could  combine  an  investment  in the  Income  Stock Fund with
investments  in other  mutual  funds  that  invest in stocks of large and small
companies  and  high-dividend  stocks.  This is just one way you could  combine
funds that fit your own risk and reward goals.

III. USAA's Family of Funds
   
We offer you another  alternative for asset  allocation with our asset strategy
funds  listed on page 18. These unique  mutual funds  provide a  professionally
managed  diversified  investment  portfolio  within  a  mutual  fund.  They are
designed  for the  individual  who  prefers to  delegate  the asset  allocation
process to an investment manager and are structured to achieve  diversification
across a number of investment categories. 
    
Whether you prefer to create  your own mix of mutual  funds or use a USAA Asset
Strategy  Fund,  the USAA  Family of Funds  provides  a broad  range of choices
covering  just  about  any   investor's   investment   objectives.   Our  sales
representatives  stand  ready to assist you with your  choices  and to help you
craft a portfolio which meets your needs. 

HOW TO INVEST

Purchase of Shares

OPENING AN ACCOUNT
   
You may open an account and make an investment  as described  below by mail, in
person,  bank wire,  electronic  funds  transfer  (EFT),  or phone. A complete,
signed application is required for each new account.
    
TAX ID NUMBER  
Each shareholder  named on the account must provide a social security number or
tax identification number to avoid possible withholding requirements. 

EFFECTIVE DATE 
When you make a purchase, your purchase price will be the net asset value (NAV)
per share next  determined  after we  receive  your  request in proper  form as
described  below.  The Fund's  NAV is  determined  at the close of the  regular
trading  session  (generally  4:00  p.m.  Eastern  Time) of the New York  Stock
Exchange  (NYSE) each day the NYSE is open. If we receive your request prior to
that time,  your purchase  price will be the NAV per share  determined for that
day. If we receive  your  request  after the NAV per share is  calculated,  the
purchase  will be effective on the next  business  day. If you plan to purchase
Fund shares with a foreign check,  we suggest you convert your foreign check to
U.S.  dollars prior to investment in the Fund to avoid a potential delay in the
effective date of your purchase of up to four to six weeks. Furthermore, a bank
charge may be assessed in the clearing process, which will be deducted from the
amount of the purchase.

Redemption of Shares

You may redeem Fund shares by any of the methods described below on any day the
NAV per share is calculated.  Redemptions are effective on the day instructions
are received in a manner as  described  below.  However,  if  instructions  are
received  after  the NAV per share  calculation  (generally  4:00 p.m.  Eastern
Time), redemption will be effective on the next business day. 

Within seven days after the effective date of redemption, we will send you your
money. Payment for redemption of shares purchased by EFT or check is sent after
the EFT or check has cleared,  which could take up to 15 days from the purchase
date. If you are considering  redeeming shares soon after purchase,  you should
purchase by bank wire or certified check to avoid delay.

In  addition,  the  Company may elect to suspend  the  redemption  of shares or
postpone the date of payment in limited circumstances.

IMPORTANT INFORMATION ABOUT
PURCHASES AND REDEMPTIONS

Investor's Guide to USAA Mutual Fund Services

Upon your initial  investment with us, you will receive the INVESTOR'S GUIDE to
help you get the most out of your USAA mutual  fund  account and to help you in
your role as an investor.  In the INVESTOR'S  GUIDE,  you will find  additional
information on purchases,  redemptions,  and methods of payment.  You will also
find in-depth information on automatic investment plans, shareholder statements
and reports, and other useful information.

Account Balance

Beginning in September  1998,  and occurring each  September  thereafter,  USAA
Shareholder  Account Services (SAS),  the Fund's transfer agent,  will assess a
small balance account fee of $12 to each shareholder account with a balance, at
the time of assessment, of less than $2,000. The fee will reduce total transfer
agency fees paid by the Fund to SAS. Accounts exempt from the fee include:  (1)
any  account  regularly  purchasing  additional  shares  each month  through an
automatic  investment  plan;  (2) any  account  registered  under  the  Uniform
Gifts/Transfers to Minors Act (UGMA/UTMA);  (3) all (non-IRA) money market fund
accounts;  (4) any account whose registered  owner has an aggregate  balance of
$50,000 or more  invested in USAA mutual  funds;  and (5) all IRA accounts (for
the first year the account is open).

Company Rights 

The Company reserves the right to:

o    reject  purchase  or  exchange  orders  when in the best  interest  of the
     Company; 

o    limit or  discontinue  the  offering  of  shares of any  portfolio  of the
     Company without notice to the  shareholders;  

o    impose a  redemption  charge of up to 1% of the net asset  value of shares
     redeemed  if  circumstances   indicate  a  charge  is  necessary  for  the
     protection of remaining investors (for example, if excessive market-timing
     share activity unfairly burdens  long-term  investors);  however,  this 1%
     charge will not be imposed  upon  shareholders  unless  authorized  by the
     Board of Directors and the required notice has been given to shareholders;

                                      13
<PAGE>

o    require a signature  guarantee for purchases,  redemptions,  or changes in
     account  information in those  instances  where the  appropriateness  of a
     signature  authorization  is in  question.  The  Statement  of  Additional
     Information contains information on acceptable guarantors;

o    redeem an account with less than 10 shares, with certain limitations.

EXCHANGES

Exchange Privilege

The exchange privilege is automatic when you complete your application. You may
exchange  shares  among Funds in the USAA Family of Funds,  provided you do not
hold these shares in stock  certificate  form and the shares to be acquired are
offered  in  your  state  of  residence.   The  Fund's   transfer   agent  will
simultaneously  process exchange  redemptions and purchases at the share prices
next  determined  after the exchange order is received.  For federal income tax
purposes,  an exchange  between Funds is a taxable event;  and as such, you may
realize a capital gain or loss.
   
The Fund has undertaken certain procedures regarding telephone  transactions as
described on page 12.
    
Exchange Limitations, Excessive Trading
   
To  minimize  Fund costs and to protect the Funds and their  shareholders  from
unfair expense burdens,  the Funds restrict excessive  exchanges.  The limit on
exchanges  out of any Fund in the USAA Family of Funds for each  account is six
per calendar  year (except  there is no  limitation on exchanges out of the Tax
Exempt Short-Term Fund,  Short-Term Bond Fund, or any of the money market funds
in the USAA Family of Funds). 
    
SHAREHOLDER INFORMATION

Share Price Calculation

The price at which shareholders purchase and redeem Fund shares is equal to the
net asset  value  (NAV)  per  share  determined  on the  effective  date of the
purchase or  redemption.  You may buy and sell Fund shares at the NAV per share
without a sales charge.

When

The  Fund's NAV per share is  calculated  at the close of the  regular  trading
session of the NYSE, which is usually 4:00 p.m. Eastern Time.

                                      14
<PAGE>

How

The NAV per share is calculated by adding the value of all securities and other
assets in the Fund, deducting liabilities, and dividing by the number of shares
outstanding.

Dividends and Distributions

The Fund pays net investment income dividends  quarterly.  Any net capital gain
distribution  usually  occurs  within 45 days of the July 31  fiscal  year end,
which would be  somewhere  around the middle of  September.  The Fund will make
additional payments to shareholders,  if necessary,  to avoid the imposition of
any federal income or excise tax.

All  income  dividends  and  capital  gain   distributions   are  automatically
reinvested,  unless we receive different instructions from you. The share price
will be the NAV of the Fund shares computed on the ex-dividend date. Any income
dividends  or capital gain  distributions  paid by the Fund will reduce the NAV
per share by the amount of the dividend or  distribution.  These  dividends and
distributions are subject to taxes. 

We will invest any  dividend  or  distribution  payment  returned to us in your
account at the  then-current NAV per share.  Dividend and  distribution  checks
become  void six months  from the date on the  check.  The amount of the voided
check will be invested in your account at the then-current NAV per share.

Federal Taxes

This tax  information  is quite  general and refers to the  federal  income tax
provisions in effect as of the date of this Prospectus.  Note that the recently
enacted Taxpayer Relief Act of 1997 and regulations that will likely be created
to  implement   the  Act  may  affect  the  status  and  treatment  of  certain
distributions  shareholders  receive from the Fund. We urge you to consult your
own tax  adviser  about the status of  distributions  from the Fund in your own
state and locality.

FUND - The Fund  intends to qualify as a  regulated  investment  company  (RIC)
under Subchapter M of the Internal Revenue Code of 1986, as amended.  As a RIC,
the Fund will not be subject to federal income tax on its net investment income
and net capital gains distributed to shareholders.  Net capital gains are those
gains in excess of capital losses.

SHAREHOLDER - Dividends from taxable net investment income and distributions of
net short-term  capital gains are taxable to shareholders  as ordinary  income,
whether received in cash or reinvested in additional shares. A portion of these
dividends may qualify for the 70%  dividends  received  deduction  available to
corporations.

                                      15
<PAGE>

Regardless  of the length of time you have held the Fund shares,  distributions
of net long-term  capital gains are taxable as long-term  capital gains whether
received in cash or reinvested in additional shares.  

Redemptions  and  exchanges  are subject to income tax based on the  difference
between  the  cost of  shares  when  purchased  and  the  price  received  upon
redemption or exchange.

WITHHOLDING  - Federal law  requires the Fund to withhold and remit to the U.S.
Treasury a portion of the income dividends and capital gain  distributions  and
proceeds of redemptions paid to any non-corporate shareholder who:

o    fails to furnish the Fund with a correct tax identification number,
o    underreports dividend or interest income, or
o    fails to certify that he or she is not subject to withholding.  

To avoid this withholding requirement, you must certify on your application, or
on a separate  Form W-9 supplied by the Fund's  transfer  agent,  that your tax
identification  number is correct and you are not  currently  subject to backup
withholding.

REPORTING - The Fund will report annually to you information concerning the tax
status of dividends and distributions for federal income tax purposes.

DESCRIPTION OF SHARES 

The Fund is a series of USAA Mutual Fund,  Inc.  (Company) and is  diversified.
The Company is an open-end management investment company incorporated under the
laws of the State of  Maryland.  The Company is  authorized  to issue shares of
common  stock of separate  series,  each of which is commonly  referred to as a
mutual fund. There are ten mutual funds in the Company, including this Fund.
   
The Company does not hold annual or regular  meetings of shareholders and holds
special  meetings only as required by the  Investment  Company Act of 1940. The
Directors  may fill  vacancies  on the Board or appoint  new  Directors  if the
result is that at least  two-thirds of the Directors have still been elected by
shareholders.  Shareholders have one vote per share (with proportionate  voting
for  fractional  shares)  regardless  of the  relative  net asset  value of the
shares. If a matter affects an individual fund in the Company,  there will be a
separate  vote  of  the  shareholders  of  that  specific  fund.   Shareholders
collectively  holding at least 10% of the outstanding shares of the Company may
request a  shareholder  meeting at any time for the purpose of voting to remove
one or more of the Directors. The Company will assist in communicating to other
shareholders about the meeting.

                                   APPENDIX A

THE FOLLOWING ARE  DESCRIPTIONS  OF CERTAIN TYPES OF SECURITIES IN WHICH WE MAY
INVEST THE FUND'S ASSETS:  

CONVERTIBLE SECURITIES
   
We may invest in convertible securities, which are bonds, preferred stocks, and
other  securities that pay interest or dividends and offer the buyer the option
of  converting  the  security  into  common  stock.  The  value of  convertible
securities depends partially on interest rate changes and the credit quality of
the issuer. Because a convertible security affords an investor the opportunity,
through its conversion feature,  to participate in the capital  appreciation of
the underlying  common stock, the value of convertible  securities also depends
on the price of the underlying common stock.
    
ILLIQUID SECURITIES
We may not invest more than 15% of the market value of the Fund's net assets in
securities  which are illiquid.  Illiquid  securities are those securities that
cannot be disposed of in the ordinary  course of business in seven days or less
at approximately the value at which the Fund has valued the securities.

MONEY MARKET INSTRUMENTS
    
We may hold a  certain  portion  of the  Fund's  assets in  high-quality,  U.S.
dollar-denominated  debt securities that have remaining  maturities of one year
or less. Such securities may include U.S.  Government  obligations,  commercial
paper  and  other  short-term  corporate  obligations,   repurchase  agreements
collateralized  with  U.S.  Government  securities,  certificates  of  deposit,
bankers'   acceptances,   bank  deposits,   and  other  financial   institution
obligations. These securities may carry fixed or variable interest rates.
    
CALL OPTIONS
We may write  covered  call  options  with  respect  to not more than 5% of the
Fund's total assets.

You may see the Fund's total return quoted in advertisements  and reports.  All
mutual funds must use the same formula to calculate total return.  Yield is the
annualized  net  income  of the Fund  during a  specified  30-day  period  as a
percentage of the Fund's share price. Total return measures the price change in
a share  assuming  the  reinvestment  of all  dividend  income and capital gain
distributions.  You may also see a comparison of the Fund's performance to that
of  other  mutual  funds  with  similar  investment  objectives  and to bond or
relevant indexes.
    
For the following  periods ended  September 30, 1997, the Fund's average annual
total returns have been:
   
               1 Year................................   11.55%
               5 Years...............................    7.35%
              10 Years...............................   10.31%
    
Figures  on page 5 are  different  because  they are for  periods  which  ended
December 31, 1996. 

WILL THE VALUE OF YOUR INVESTMENT FLUCTUATE?  
   
Yes, it will. The value of your investment could increase or decrease.  The bar
chart and table shown on the next page  illustrate  the Fund's  volatility  and
performance  from year to year over the past ten years and shows how the Fund's
average annual returns for the one-,  five-,  and ten-year  periods  compare to
those of a broad-based  securities  market index.  Again,  remember  historical
performance might not be repeated in the future.

A WORD ABOUT RISK
   
Portions of this Prospectus  describe the risks you will face as an investor in
the  Fund.  Keep in mind that  generally  investments  with a higher  potential
reward also have a higher risk of losing money.  The reverse is also  generally
true:  the lower the risk,  the lower the  potential  reward.  However,  as you
consider an  investment  in the Fund,  you should also take into  account  your
tolerance for the daily  fluctuations of the financial  markets and whether you
can afford to leave your money in this  investment  for long periods of time to
ride out down periods.  
    
[CAUTION LIGHT GRAPHIC]
Look for this symbol  throughout  the  Prospectus.  We use it to mark  detailed
information about the main risks that you will face as a Fund shareholder.

FUND INVESTMENTS

Investment Policies and Risks

   Q   What is the Fund's investment policy?

   A   We will invest the Fund's  assets  primarily in U.S.  dollar-denominated
       securities that have been selected for their high yields relative to the
       risk involved. Consistent with this policy, when interest rates rise, we
       will  invest a greater  portion of the Fund's  portfolio  in  securities
       whose value we believe to be less sensitive to interest rate changes.
   
       As a temporary defensive measure, we may invest up to 100% of the Fund's
       assets in high-quality, short-term debt instruments.
    
[CAUTION  LIGHT  GRAPHIC]  
INTEREST RATE RISK. As a mutual fund investing in bonds, the Fund is subject to
the risk that the market value of the bonds will decline due to rising interest
rates.  Bond prices are linked to the  prevailing  market  interest  rates.  In
general,  when interest  rates rise, the prices of bonds fall and when interest
rates fall,  bond prices  generally  rise. The price  volatility of a bond also
depends on its  maturity.  Generally,  the longer the  maturity of a bond,  the
greater its  sensitivity to interest  rates.  To compensate  investors for this
higher risk,  bonds with longer  maturities  generally offer higher yields than
bonds with shorter maturities.

   Q   What types of securities will the Fund's portfolio consist of?

   A   The Fund's portfolio may consist of any of the follwing:

       o Obligations of the U.S. Government, its agents, and instrumentalities;
       o Mortgage-backed securities; o Asset-backed securities;
       o Corporate debt securities such as notes, bonds, and commercial paper;
       o Debt securities of real estate investment trusts;
       o U.S. bank obligations,  including certificates of deposit and banker's
         acceptances;
       o Obligations  of state and local  governments  and their  agencies  and
         instrumentalities;
       o Master demand notes;
       o Eurodollar obligations;

                                       6
<PAGE>

       o Yankee obligations;
       o Other debt securities;
       o Common stocks;
       o Preferred stocks.
   
       Further description of these securities is  found in APPENDIX A on page 
       18.
    
   Q   What will be the quality of debt  securities that the Fund's assets will
       be invested in?

   A   We will invest the Fund's assets in debt  securities,  which at the time
       of purchase, must be investment grade.  Investment-grade  securities are
       those  securities  issued  or  guaranteed  by the U.S.  Government,  its
       agencies,  and  instrumentalities;  those rated  within the four highest
       long-term rating categories by: 

       o Moody's Investors Services, Inc.,
       o Standard & Poor's Ratings Group,
       o Fitch Investors Service, Inc., or
       o Duff and Phelps;

       or . . . if  unrated  by those  four  agencies,  we must determine that 
       these securities are of equivalent investment quality.

   Q   What happens if the rating of a security is downgraded?

   A   If the rating of a security is downgraded  below  investment  grade,  we
       will  determine  whether  it is in  the  best  interest  of  the  Fund's
       shareholders  to continue to hold the security in the Fund's  portfolio.
       If  downgrades  result in more than 5% of the Fund's  net  assets  being
       invested in securities that are less than  investment-grade  quality, we
       will take  immediate  action  to  reduce  the  Fund's  holdings  in such
       securities  to 5% or less of the Fund's  net  assets,  unless  otherwise
       directed by the Board of Directors.

[CAUTION LIGHT GRAPHIC]
CREDIT RISK.  Credit risk is the  possibility  that an issuer of a fixed income
instrument  such as a bond or  repurchase  agreement  will fail to make  timely
payments of interest or  principal.  We attempt to minimize  the Fund's  credit
risk by  investing in  securities  considered  investment  grade at the time of
purchase. When evaluating potential investments for the Fund, our analysts also
assess credit risk and its impact on the Fund's portfolio.  Nevertheless,  even
investment-grade  securities are subject to some credit risk. Securities in the
lowest-rated,   investment-grade  category  have  speculative  characteristics.
Changes in 

                                       7
<PAGE>

economic  conditions  or  other  circumstances  are  more  likely  to lead to a
weakened capability to make principal and interest payments on these securities
than is the case for  higher-rated  securities.  In  addition,  the  ratings of
securities  are estimates by the rating  agencies of the credit  quality of the
securities.  The ratings may not take into account  every risk that interest or
principal will be repaid on a timely basis.

   Q   What other risks apply to the Fund's portfolio?

   A   MARKET RISK.  Because  this Fund  invests in equity  securities,  it is
       subject to market  risk.  Stock prices in general may decline over short
       or even  extended  periods,  regardless  of the success or failure of an
       individual  company's  operations.  The  stock  market  tends  to run in
       cycles,  with periods when stock prices generally go up and periods when
       stock prices generally go down. Equity securities tend to go up and down
       more than bonds.
   
For additional  information  about other  securities in which we may invest the
Fund's assets, see APPENDIX A on page 18.
    
Investment Restrictions

The following restrictions may only be changed with shareholder approval: 

       o The Fund may not  invest  more  than 25% of its  total  assets  in one
         industry.

       o The Fund may not  invest  more than 5% of its total  assets in any one
         issuer or own more than 10% of the  outstanding  voting  securities of
         any one  issuer.  This  limitation  does not apply to U.S.  Government
         securities, and only applies to 75% of the Fund's total assets.

       o The Fund may borrow only for  temporary  or  emergency  purposes in an
         amount not exceeding 33 1/3% of its total assets.

You will find a complete listing of the precise investment  restrictions in the
Fund's Statement of Additional Information.

USING MUTUAL FUNDS IN
AN INVESTMENT PROGRAM

I. The Idea Behind Mutual Funds

Mutual funds provide small investors some of the advantages  enjoyed by wealthy
investors.  A  relatively  small  investment  can  buy  part  of a  diversified
portfolio. That portfolio is managed by investment professionals, relieving you
of the  need to make  individual  stock  or bond  selections.  You  also  enjoy
conveniences,  such as daily  pricing,  liquidity,  and in the case of the USAA
Family of Funds, no sales charge. The portfolio, because of its size, has lower
transaction  costs on its trades than most individuals would have. As a result,
you own an investment  that in earlier times would have been  available only to
very wealthy people.

                                       9
<PAGE>

II. Using Funds in an Investment Program

In  choosing a mutual  fund as an  investment  vehicle,  you are giving up some
investment decisions,  but must still make others. The decisions you don't have
to make are those involved with choosing individual securities. We will perform
that function.  In addition, we will arrange for the safekeeping of securities,
auditing the annual financial  statements,  and daily valuation of the Fund, as
well  as  other  functions.   

You,  however,  retain  at  least  part of the  responsibility  for an  equally
important  decision.  This decision involves  determining a portfolio of mutual
funds that balances your  investment  goals with your tolerance for risk. It is
likely that this decision may include the use of more than one fund of the USAA
Family of Funds. 

For example, assume you wish to invest in a widely-diversified  portfolio.  You
could combine an investment in the Income Fund with investments in other mutual
funds  that  invest in stocks of large and small  companies  and  high-dividend
stocks. This is just one way you could combine funds that fit your own risk and
reward goals.

III. USAA's Family of Funds
   
We offer you another  alternative for asset  allocation with our asset strategy
funds  listed on page 21. These unique  mutual funds  provide a  professionally
managed  diversified  investment  portfolio  within  a  mutual  fund.  They are
designed  for the  individual  who  prefers to  delegate  the asset  allocation
process to an investment manager and are structured to achieve  diversification
across a number of investment categories.
    
Whether you prefer to create  your own mix of mutual  funds or use a USAA Asset
Strategy  Fund,  the USAA  Family of Funds  provides  a broad  range of choices
covering  just  about  any   investor's   investment   objectives.   Our  sales
representatives  stand  ready to assist you with your  choices  and to help you
craft a portfolio which meets your needs. 

HOW TO INVEST

Purchase of Shares

OPENING AN ACCOUNT
   
You may open an account and make an investment  as described  below by mail, in
person,  bank wire,  electronic  funds  transfer  (EFT),  or phone. A complete,
signed  application  is  required  for each new  account.  
    
TAX ID NUMBER  
Each shareholder  named on the account must provide a social security number or
tax identification number to avoid possible withholding requirements.

                                      10
<PAGE>

EFFECTIVE DATE 
When you make a purchase, your purchase price will be the net asset value (NAV)
per share next  determined  after we  receive  your  request in proper  form as
described  below.  The Fund's  NAV is  determined  at the close of the  regular
trading  session  (generally  4:00  p.m.  Eastern  Time) of the New York  Stock
Exchange  (NYSE) each day the NYSE is open. If we receive your request prior to
that time,  your purchase  price will be the NAV per share  determined for that
day. If we receive  your  request  after the NAV per share is  calculated,  the
purchase  will be effective on the next  business  day. If you plan to purchase
Fund shares with a foreign check,  we suggest you convert your foreign check to
U.S.  dollars prior to investment in the Fund to avoid a potential delay in the
effective date of your purchase of up to four to six weeks. Furthermore, a bank
charge may be assessed in the clearing process, which will be deducted from the
amount of the purchase.

Redemption of Shares

You may redeem Fund shares by any of the methods described below on any day the
NAV per share is calculated.  Redemptions are effective on the day instructions
are received in a manner as  described  below.  However,  if  instructions  are
received  after  the NAV per share  calculation  (generally  4:00 p.m.  Eastern
Time), redemption will be effective on the next business day. 

Within seven days after the effective date of redemption, we will send you your
money. Payment for redemption of shares purchased by EFT or check is sent after
the EFT or check has cleared,  which could take up to 15 days from the purchase
date. If you are considering  redeeming shares soon after purchase,  you should
purchase by bank wire or certified check to avoid delay.

In  addition,  the  Company may elect to suspend  the  redemption  of shares or
postpone the date of payment in limited circumstances.

IMPORTANT INFORMATION ABOUT PURCHASES AND REDEMPTIONS

Investor's Guide to USAA Mutual Fund Services

Upon your initial  investment with us, you will receive the INVESTOR'S GUIDE to
help you get the most out of your USAA mutual  fund  account and to help you in
your role as an investor.  In the INVESTOR'S  GUIDE,  you will find  additional
information on purchases,  redemptions,  and methods of payment.  You will also
find in-depth information on automatic investment plans, shareholder statements
and reports, and other useful information.

Account Balance

Beginning in September  1998,  and occurring each  September  thereafter,  USAA
Shareholder  Account Services (SAS),  the Fund's transfer agent,  will assess a
small balance account fee of $12 to each shareholder account with a balance, at
the time of assessment, of less than $2,000. The fee will reduce total transfer
agency fees paid by the Fund to SAS. Accounts exempt from the fee include:  (1)
any  account  regularly  purchasing  additional  shares  each month  through an
automatic  investment  plan;  (2) any  account  registered  under  the  Uniform

                                      13
<PAGE>

Gifts/Transfers to Minors Act (UGMA/UTMA);  (3) all (non-IRA) money market fund
accounts;  (4) any account whose registered  owner has an aggregate  balance of
$50,000 or more  invested in USAA mutual  funds;  and (5) all IRA accounts (for
the first year the account is open).

Company Rights 

The Company reserves the right to:

o   reject  purchase  or  exchange  orders  when in the best  interest  of the
    Company;

o   limit or discontinue the offering of shares of any portfolio of the Company
    without notice to the shareholders;

o   impose a  redemption  charge of up to 1% of the net  asset  value of shares
    redeemed if circumstances indicate a charge is necessary for the protection
    of remaining  investors  (for  example,  if excessive  market-timing  share
    activity unfairly burdens  long-term  investors);  however,  this 1% charge
    will not be imposed upon  shareholders  unless  authorized  by the Board of
    Directors and the required notice has been given to shareholders;

o   require a signature  guarantee for  purchases,  redemptions,  or changes in
    account  information  in those  instances  where the  appropriateness  of a
    signature  authorization  is  in  question.  The  Statement  of  Additional
    Information contains information on acceptable guarantors;

o   redeem an account with less than 10 shares, with certain limitations.

EXCHANGES

Exchange Privilege

The exchange privilege is automatic when you complete your application. You may
exchange  shares  among Funds in the USAA Family of Funds,  provided you do not
hold these shares in stock  certificate  form and the shares to be acquired are
offered  in  your  state  of  residence.   The  Fund's   transfer   agent  will
simultaneously  process exchange  redemptions and purchases at the share prices
next  determined  after the exchange order is received.  For federal income tax
purposes,  an exchange  between Funds is a taxable event;  and as such, you may
realize a capital  gain or loss. 
   
The Fund has undertaken certain procedures regarding telephone  transactions as
described on page 13.

Exchange Limitations, Excessive Trading
   
To  minimize  Fund costs and to protect the Funds and their  shareholders  from
unfair expense burdens,  the Funds restrict excessive  exchanges.  The limit on
exchanges  out of any Fund in the USAA Family of Funds for each  account is six
per calendar  year (except  there is no  limitation on exchanges out of the Tax
Exempt Short-Term Fund,  Short-Term Bond Fund, or any of the money market funds
in the USAA Family of Funds). 
    
SHAREHOLDER INFORMATION

Share Price Calculation

The price at which shareholders purchase and redeem Fund shares is equal to the
net asset  value  (NAV)  per  share  determined  on the  effective  date of the
purchase or  redemption.  You may buy and sell Fund shares at the NAV per share
without a sales charge.

When

The  Fund's NAV per share is  calculated  at the close of the  regular  trading
session of the NYSE, which is usually 4:00 p.m. Eastern Time.

How

The NAV per share is calculated by adding the value of all securities and other
assets in the Fund, deducting liabilities, and dividing by the number of shares
outstanding.

Dividends and Distributions

The Fund pays net  investment  income  monthly  based on the  projection of its
annual  net  investment   income.   Therefore,   the  amount  of  each  monthly
distribution  may be  different  from the actual  net  investment  income.  The
purpose of this  distribution  procedure  is to attempt to provide  you with an
even monthly distribution  payment. If the total distributions in a year exceed
net  investment  income  for  the  Fund's  current  year,  a  portion  of  your
distributions  could be a return of capital for federal income tax purposes and
thereby  reduce  your  cost  basis  in  the  Fund's  shares.   If  you  receive
distributions  in additional Fund shares rather than cash, the capital returned
would be automatically reinvested,  and your total cost basis in the Fund would
remain the same.  Any net capital gains  distribution  usually occurs within 45
days of the July 31 fiscal year end which would be somewhere  around the middle
of  September.  The Fund will make  additional  payments  to  shareholders,  if
necessary, to avoid the imposition of any federal income or excise tax.

                                      15
<PAGE>

All  income  dividends  and  capital  gain   distributions   are  automatically
reinvested,  unless we receive different instructions from you. The share price
will be the NAV of the Fund shares computed on the ex-dividend date. Any income
dividends  or capital gain  distributions  paid by the Fund will reduce the NAV
per share by the amount of the dividend or  distribution.  These  dividends and
distributions are subject to taxes.

We will invest any  dividend  or  distribution  payment  returned to us in your
account at the  then-current NAV per share.  Dividend and  distribution  checks
become  void six months  from the date on the  check.  The amount of the voided
check will be invested in your account at the then-current NAV per share.

Federal Taxes

This tax  information  is quite  general and refers to the  federal  income tax
provisions in effect as of the date of this Prospectus.  Note that the recently
enacted Taxpayer Relief Act of 1997 and regulations that will likely be created
to  implement   the  Act  may  affect  the  status  and  treatment  of  certain
distributions  shareholders  receive from the Fund. We urge you to consult your
own tax  adviser  about the status of  distributions  from the Fund in your own
state and locality.

FUND - The Fund  intends to qualify as a  regulated  investment  company  (RIC)
under Subchapter M of the Internal Revenue Code of 1986, as amended.  As a RIC,
the Fund will not be subject to federal income tax on its net investment income
and net capital gains distributed to shareholders.  Net capital gains are those
gains in excess of capital losses.

SHAREHOLDER - Dividends from taxable net investment income and distributions of
net short-term  capital gains are taxable to shareholders  as ordinary  income,
whether received in cash or reinvested in additional shares. A portion of these
dividends may qualify for the 70%  dividends  received  deduction  available to
corporations.

Regardless  of the length of time you have held the Fund shares,  distributions
of net long-term  capital gains are taxable as long-term  capital gains whether
received in cash or reinvested in additional shares.

Redemptions  and  exchanges  are subject to income tax based on the  difference
between  the  cost of  shares  when  purchased  and  the  price  received  upon
redemption or exchange.

WITHHOLDING - Federal  law  requires the Fund to withhold and remit to the U.S.
Treasury a portion of the income dividends and capital gain  distributions  and
proceeds of redemptions paid to any non-corporate shareholder who:

o    fails to furnish the Fund with a correct tax identification number,
o    underreports dividend or interest income, or 
o    fails to certify that he or she is not subject to withholding.

                                      16
<PAGE>

To avoid this withholding requirement, you must certify on your application, or
on a separate  Form W-9 supplied by the Fund's  transfer  agent,  that your tax
identification  number is correct and you are not  currently  subject to backup
withholding.

REPORTING - The Fund will report annually to you information concerning the tax
status of dividends and distributions for federal income tax purposes.

DESCRIPTION OF SHARES 

The Fund is a series of USAA Mutual Fund,  Inc.  (Company) and is  diversified.
The Company is an open-end management investment company incorporated under the
laws of the State of  Maryland.  The Company is  authorized  to issue shares of
common  stock of separate  series,  each of which is commonly  referred to as a
mutual fund. There are ten mutual funds in the Company, including this Fund.
   
The Company does not hold annual or regular  meetings of shareholders and holds
special  meetings only as required by the  Investment  Company Act of 1940. The
Directors  may fill  vacancies  on the Board or appoint  new  Directors  if the
result is that at least  two-thirds of the Directors have still been elected by
shareholders.  Shareholders have one vote per share (with proportionate  voting
for  fractional  shares)  regardless  of the  relative  net asset  value of the
shares. If a matter affects an individual fund in the Company,  there will be a
separate  vote  of  the  shareholders  of  that  specific  fund.   Shareholders
collectively  holding at least 10% of the outstanding shares of the Company may
request a  shareholder  meeting at any time for the purpose of voting to remove
one or more of the Directors. The Company will assist in communicating to other
shareholders about the meeting.

                                   APPENDIX A

THE FOLLOWING ARE  DESCRIPTIONS  OF CERTAIN TYPES OF SECURITIES IN WHICH WE MAY
INVEST THE FUND'S ASSETS:

PUT BONDS 
We may invest in securities (including securities with variable interest rates)
which may be  redeemed  or sold back (put) to the issuer of the  security  or a
third party prior to stated maturity (put bonds). Such securities will normally
trade as if maturity is the earlier put date,  even though  stated  maturity is
longer.

REPURCHASE AGREEMENTS 
We may invest in repurchase  agreements which are collateralized by obligations
issued   or   guaranteed   by  the   U.S.   Government,   its   agencies,   and
instrumentalities.  A repurchase agreement is a transaction in which a security
is purchased  with a  simultaneous  commitment to sell it back to the seller (a
commercial bank or recognized  securities dealer) at an agreed upon price on an
agreed  upon date.  This date is usually not more than seven days from the date
of purchase.  The resale price  reflects the purchase price plus an agreed upon
market rate of  interest,  which is unrelated to the coupon rate or maturity of
the purchased security.

VARIABLE RATE SECURITIES 
We may invest in  securities  that bear  interest at rates  which are  adjusted
periodically to market rates.

o    These  interest  rate  adjustments  can both  raise and  lower the  income
     generated by such  securities.  These changes will have the same effect on
     the  income  earned  by the  Fund  depending  on the  proportion  of  such
     securities held.

o    The value of variable rate  securities is less affected than  fixed-coupon
     securities by changes in prevailing interest rates because of the periodic
     adjustment  of their  coupons to a market  rate.  The  shorter  the period
     between adjustments,  the smaller the impact of interest rate fluctuations
     on the value of these securities.

o    The market  value of a variable  rate  security  usually  tends toward par
     (100% of face value) at interest rate adjustment time.

WHEN-ISSUED SECURITIES 
We may invest in new issues of debt securities  offered on a when-issued basis.

o    Delivery  and  payment  take  place  after the date of the  commitment  to
     purchase,  normally within 45 days. Both price and interest rate are fixed
     at the time of commitment.

o    The Fund does not earn interest on the securities  until  settlement,  and
     the market value of the  securities  may  fluctuate  between  purchase and
     settlement.

o    Such securities can be sold before settlement date.  

MORTGAGE-BACKED AND ASSET-BACKED SECURITIES 
We may invest the Fund's assets in mortgage-backed and asset-backed securities.
Mortgage-backed  securities include,  but are not limited to, securities issued
by the  Government  National  Mortgage  Association  (Ginnie Mae),  the Federal
National Mortgage  Association  (Fannie Mae) and the Federal Home Loan Mortgage
Corporation  (Freddie Mac). These securities  represent  ownership in a pool of
mortgage loans. They differ from  conventional  bonds in that principal is paid
back to the  investor as payments are made on the  underlying  mortgages in the
pool.  Accordingly,  the Fund receives monthly scheduled  payments of principal
and interest along with any unscheduled principal prepayments on

                                      18
<PAGE>

the underlying  mortgages.  Because these scheduled and  unscheduled  principal
payments  must be  reinvested at  prevailing  interest  rates,  mortgage-backed
securities do not provide an effective  means of locking in long-term  interest
rates for the investor. Like other fixed income securities, when interest rates
rise, the value of a mortgage-backed security generally will decline;  however,
when interest rates are declining, the value of mortgage-backed securities with
prepayment  features may not increase as much as other fixed income securities.

Mortgage-backed  securities also include  collateralized  mortgage  obligations
(CMOs).  CMOs are obligations fully  collateralized by a portfolio of mortgages
or  mortgage-related  securities.  CMOs are divided into pieces (tranches) with
varying maturities.  The cash flow from the underlying mortgages is used to pay
off each tranche  separately.  CMOs are designed to provide investors with more
predictable maturities than regular mortgage securities but such maturities can
be  difficult  to  predict  because of the  effect of  prepayments.  Failure to
accurately predict  prepayments can adversely affect the Fund's return on these
investments.   CMOs  may  also  be  less  marketable  than  other   securities.

Asset-backed  securities  represent a  participation  in, or are secured by and
payable  from, a stream of payments  generated by  particular  assets,  such as
credit card,  motor vehicle,  or trade  receivables.  They may be  pass-through
certificates,  which  have  characteristics  very  similar  to  mortgage-backed
securities,  discussed  above.  They may  also be in the  form of  asset-backed
commercial paper, which is issued by a special purpose entity, organized solely
to issue the  commercial  paper and to purchase  interests  in the assets.  The
credit quality of these  securities  depends  primarily upon the quality of the
underlying assets and the level of credit support and enhancement provided. 

The weighted  average  life of such  securities  is likely to be  substantially
shorter  than their stated  final  maturity as a result of scheduled  principal
payments  and  unscheduled   principal   prepayments.   

EURODOLLAR AND YANKEE OBLIGATIONS 
We may invest a portion of the Fund's assets in dollar-denominated  instruments
that have been issued outside the U.S. capital markets by foreign  corporations
and financial  institutions  and by foreign  branches of U.S.  corporations and
financial institutions  (Eurodollar) as well as dollar-denominated  instruments
that have been issued by foreign issuers in the U.S. capital markets  (Yankee).
In addition,  we may invest a portion of the Fund's  assets in  Eurodollar  and
Yankee obligations of investment-grade emerging market countries. 

MASTER DEMAND NOTES 
We may invest the Fund's assets in master demand notes,  which are  obligations
that permit the investment of fluctuating amounts by the Fund, at varying rates
of interest  using direct  arrangements  between the Fund,  as lender,  and the
borrower.  These notes permit daily changes in the amounts  borrowed.  The Fund
has the right to increase  the amount under the note at any time up to the full
amount  provided  by the note  agreement,  or to decrease  the amount,  and the
borrower  may  repay  up to the  full  amount  of  the  note  without  penalty.
Frequently,  such  obligations are secured by letters of credit or other credit
support arrangements  provided by banks. Because master demand notes are direct
lending  arrangements  between  the  lender  and  borrower,  these  instruments
generally will not be traded,  and there  generally is no secondary  market for
these notes,  although they are redeemable  (and  immediately  repayable by the
borrower) at face value, plus accrued interest, at any time. We will invest the
Fund's  assets in master  demand  notes only if the Board of  Directors  or its
delegate has determined that they are of credit quality  comparable to the debt
securities in which the Fund generally may invest.

                                      19
<PAGE>

   
CONVERTIBLE  SECURITIES  We may  invest in  convertible  securities,  which are
bonds,  preferred  stocks,  and other securities that pay interest or dividends
and offer the buyer the option of  converting  the security  into common stock.
The value of convertible  securities depends partially on interest rate changes
and the credit quality of the issuer. Because a convertible security affords an
investor the opportunity, through its conversion feature, to participate in the
capital  appreciation of the underlying  common stock, the value of convertible
securities also depends on the price of the underlying common stock.
    
ILLIQUID SECURITIES 
We may not invest more than 15% of the market value of the Fund's net assets in
securities  which are illiquid.  Illiquid  securities are those securities that
cannot be disposed of in the ordinary  course of business in seven days or less
at approximately the value at which the Fund has valued the securities.

FEES AND EXPENSES

This summary  shows what it will cost you directly or  indirectly  to invest in
the Fund.

Shareholder Transaction Expenses -- Fees You Pay Directly

There are no fees  charged to your  account  when you buy,  sell,  or hold Fund
shares.  However,  if you sell shares and request your money by wire  transfer,
you will pay a $10 fee. (Your bank may also charge a fee for receiving wires.)

Annual Fund Operating Expenses -- Fees You Pay Indirectly

Fund  expenses  come out of the Fund's  assets and are  reflected in the Fund's
share price and dividends.  "Other Expenses" include expenses such as custodian
and transfer agent fees. The figures below show actual  expenditures during the
past fiscal year ended July 31, 1997,  and are  calculated  as a percentage  of
average net assets (ANA).

              Management Fees (net of                    
               reimbursement)                     .13%        12b-1 FEES -

              (net of reimbursement)              .50%        SHARES.
                                                  ====

During the year, we voluntarily  limited the Fund's annual  expenses to .50% of
its ANA and reimbursed the Fund for all expenses in excess of this  limitation.
The Management Fees and Total Fund Operating  Expenses reflect all such expense
reimbursements. Without these reimbursements, the amount of the Management Fees
and Total Fund Operating  Expenses as a percentage of the Fund's ANA would have
been .24% and .61%, respectively. We have again voluntarily agreed to limit the
Fund's annual  expenses to .50% of its ANA and will  reimburse the Fund for all
expenses in excess of that amount until December 1, 1998.

Example of Effect of Fund Operating Expenses

You  would  pay the  following  expenses  on a $1,000  investment  in the Fund,
assuming  (1) 5% annual  return and (2)  redemption  at the end of the  periods
shown.

               1 year................................... $   5
               3 years..................................    16
               5 years..................................    28
              10 years..................................    63

THIS  EXAMPLE IS NOT A  REPRESENTATION  OF PAST OR FUTURE  EXPENSES  AND ACTUAL
EXPENSES MAY BE GREATER OR LESS THAN THOSE SHOWN.

You also can find the most current price of your shares in the business section
of your newspaper in the mutual fund section under the heading "USAA Group" and
the symbol "ShtTBond."
   
You may see the Fund's  yield and total  return  quoted in  advertisements  and
reports.  All mutual funds must use the same  formulas to  calculate  yield and
total return. Yield is the annualized net income of the Fund during a specified
30-day period as a percentage of the Fund's share price.  Total return measures
the price change in a share assuming the  reinvestment  of all dividend  income
and capital gain  distributions.  You may also see a  comparison  of the Fund's
performance  to that of other mutual funds with similar  investment  objectives
and to bond or relevant indexes.
    
For the following periods ended September 30, 1997, the Fund's average annual
total returns have been:
   
              1 Year...................................  8.07%
              Since Inception on June 1, 1993..........  5.92%
    
Figures  on page 5 are  different  because  they are for  periods  which  ended
December 31, 1996.

WILL THE VALUE OF YOUR INVESTMENT FLUCTUATE?
   
Yes, it will. The value of your investment could increase or decrease.  The bar
chart and table shown below  illustrate the Fund's  volatility and  performance
from year to year over the life of the Fund and  shows how the  Fund's  average
annual  returns  for one year and the  life of the Fund  compare  to those of a
broad-based  securities market index. Again,  remember  historical  performance
might not be repeated in the future.

A WORD ABOUT RISK
   
Portions of this Prospectus  describe the risks you will face as an investor in
the  Fund.  Keep in mind that  generally  investments  with a higher  potential
reward also have a higher risk of losing money.  The reverse is also  generally
true: the lower the risk, the lower the potential

                                       5
<PAGE>

reward.  However,  as you consider an investment  in the Fund,  you should also
take into account your  tolerance for the daily  fluctuations  of the financial
markets and whether you can afford to leave your money in this  investment  for
long periods of time to ride out down periods.  
    
[CAUTION LIGHT GRAPHIC]
Look for this symbol  throughout  the  Prospectus.  We use it to mark  detailed
information about the main risks that you will face as a Fund shareholder. 

FUND INVESTMENTS

Investment Policies and Risks  

DOLLAR-WEIGHTED  AVERAGE  PORTFOLIO  MATURITY IS OBTAINED  BY  MULTIPLYING  THE
DOLLAR  VALUE OF EACH  INVESTMENT  BY THE NUMBER OF DAYS LEFT TO ITS  MATURITY,
THEN ADDING  THOSE  FIGURES  TOGETHER  AND  DIVIDING BY THE DOLLAR VALUE OF THE
FUND'S PORTFOLIO.

   Q What is the Fund's investment policy?

   A We will  invest the Fund's  assets  primarily  in U.S.  dollar-denominated
     investment-grade debt securities. These debt securities must be investment
     grade at the time of purchase. We will maintain a dollar-weighted  average
     portfolio maturity of three years or less.

   Q What type of debt securities are included in the Fund's portfolio:

   A The Fund's portfolio may consist of any of the following:

     o Obligations of the U.S.  Government,its  agents, and  instrumentalities,
       and repurchase agreements collateralized by such obligations;
     o Mortgage-backed securities;
     o Asset-backed securities;
     o Corporate debt securities such as notes, bonds, and commercial paper;
     o Debt securities of real estate investment trusts;
     o U.S. bank or foreign bank obligations, including certificates of deposit
       and banker's acceptances;
     o Obligations  of state  and local  governments  and  their  agencies  and
       instrumentalities;
     o Master demand notes;
     o Eurodollar obligations;
     o Yankee obligations;
     o Other debt securities.
   
     Further description of these securities is found in APPENDIX A on page 18.
    
                                       6
<PAGE>

   Q What are considered investment-grade securities?

   A Investment-grade  securities  include securities  issued  or guaranteed by
     the  U.S. Government,  its  agencies,  and  instrumentalities,  as well as
     securities  rated within  the  categories  listed by the following  rating
     agencies:

   ____________________________________________________________________________
                                        LONG-TERM          SHORT-TERM
      RATING AGENCY                     DEBT SECURITIES    DEBT SECURITIES
   ____________________________________________________________________________
                                                           At least Prime-3 or
   Moody's Investors Services, Inc.     At least Baa       MIG 4/VMIG 4
   ----------------------------------------------------------------------------
   Standard & Poor's Ratings Group      At least BBB       At least A-3 or SP-2
   --------------------------------------------------------------------------- 
   Fitch Investors Service, Inc.        At least BBB       At least F-3
   ----------------------------------------------------------------------------
   Duff and Phelps                      At least BBB       At least D-3
   ____________________________________________________________________________

     or. . . if unrated by those four  agencies,  we must  determine that these
     securities are of equivalent investment quality.

     You will find a  complete  description  of the above  debt  ratings in the
     Fund's Statement of Additional Information.

   Q What happens if the rating of a security is downgraded?

   A If the rating of a security is downgraded below investment  grade, we will
     determine whether it is in the best interest of the Fund's shareholders to
     continue  to hold the  security  in the Fund's  portfolio.  If  downgrades
     result  in  more  than 5% of the  Fund's  net  assets  being  invested  in
     securities  that are less  than  investment-grade  quality,  we will  take
     immediate action to reduce the Fund's holdings in such securities to 5% or
     less of the Fund's net assets,  unless otherwise  directed by the Board of
     Directors.

[CAUTION LIGHT GRAPHIC]
CREDIT  RISK.  The bonds in the Fund's  portfolio  are subject to credit  risk.
Credit  risk is the  possibility  that an  issuer  of a bond  will fail to make
timely  payments of interest or  principal.  We attempt to minimize  the Fund's
credit risk by investing in securities  considered investment grade at the time
of purchase.  When evaluating potential  investments for the Fund, our analysts
also assess credit risk and its impact on the Fund's  portfolio.  Nevertheless,
even investment-grade  securities are subject to some credit risk. Bonds in the
lowest-rated  investment  grade  category  have  speculative   characteristics.
Changes in economic  conditions or other  circumstances are more likely to lead
to a weakened capability to make principal and interest payments on these bonds
than is the case for higher-rated bonds. In addition, the ratings of securities
are estimates by the rating  agencies of the credit quality of the  securities.
The ratings may not take into  account  every risk that  interest or  principal
will be repaid on a timely basis.

                                       7
<PAGE>
   
[CAUTION LIGHT GRAPHIC]
INTEREST RATE RISK. As a mutual fund investing in bonds, the Fund is subject to
the risk that the market value of the bonds will decline due to rising interest
rates.  Bond prices are linked to the  prevailing  market  interest  rates.  In
general,  when interest  rates rise, the prices of bonds fall and when interest
rates fall,  bond prices  generally  rise. The price  volatility of a bond also
depends on its  maturity.  Generally,  the longer the  maturity of a bond,  the
greater its  sensitivity to interest  rates.  To compensate  investors for this
higher risk,  bonds with longer  maturities  generally offer higher yields than
bonds  with  shorter  maturities.   

For additional  information  about other securities in which we may invest the
Fund's assets, see APPENDIX A on page 18.
    
Investment Restrictions

The following restrictions may only be changed with shareholder approval: 

o  The Fund may not invest more than 25% of its total assets in one industry.

o  The Fund may not invest  more than 5% of its total  assets in any one issuer
   or own more than 10% of the outstanding voting securities of any one issuer.
   This  limitation  does not  apply to U.S.  Government  securities,  and only
   applies to 75% of the Fund's total assets.

o  The Fund may borrow only for  temporary or  emergency  purposes in an amount
   not exceeding 33 1/3% of its total assets.  

You will find a complete listing of the precise investment  restrictions in the
Fund's Statement of Additional Information.

USING MUTUAL FUNDS IN AN INVESTMENT PROGRAM

I. The Idea Behind Mutual Funds

Mutual funds provide small investors some of the advantages  enjoyed by wealthy
investors.  A  relatively  small  investment  can  buy  part  of a  diversified
portfolio. That portfolio is managed by investment professionals, relieving you
of the  need to make  individual  stock  or bond  selections.  You  also  enjoy
conveniences,  such as daily  pricing,  liquidity,  and in the case of the USAA
Family of Funds, no sales charge. The portfolio, because of its size, has lower
transaction  costs on its trades than most individuals would have. As a result,
you own an investment  that in earlier times would have been  available only to

II. Using Funds in an Investment Program

In  choosing a mutual  fund as an  investment  vehicle,  you are giving up some
investment decisions,  but must still make others. The decisions you don't have
to make are those involved with choosing individual securities. We will perform
that function.  In addition, we will arrange for the safekeeping of securities,
auditing the annual financial  statements,  and daily valuation of the Fund, as
well as other functions.

                                       9

You,  however,  retain  at  least  part of the  responsibility  for an  equally
important  decision.  This decision involves  determining a portfolio of mutual
funds that balances your  investment  goals with your tolerance for risk. It is
likely that this decision may include the use of more than one fund of the USAA
Family of Funds. 

For example, assume you wish to invest in a widely-diversified  portfolio.  You
could combine an investment in the  Short-Term  Bond Fund with  investments  in
other  mutual  funds  that  invest in stocks of large and small  companies  and
high-dividend  stocks.  This is just one way you could  combine  funds that fit
your own risk and reward goals.

Strategy  Fund,  the USAA  Family of Funds  provides  a broad  range of choices
covering  just  about  any   investor's   investment   objectives.   Our  sales

HOW TO INVEST

Purchase of Shares

OPENING AN ACCOUNT
   
You may open an account and make an investment  as described  below by mail, in
person,  bank wire,  electronic  funds  transfer  (EFT),  or phone. A complete,
signed  application  is  required  for each new  account. 
    
TAX ID NUMBER  
Each shareholder  named on the account must provide a social security number or
tax identification number to avoid possible withholding requirements.

EFFECTIVE DATE 
When you make a purchase, your purchase price will be the net asset value (NAV)
per share next  determined  after we  receive  your  request in proper  form as
described  below.  The Fund's  NAV is  determined  at the close of the  regular
trading  session  (generally  4:00  p.m.  Eastern  Time) of the New York  Stock
Exchange  (NYSE) each day the NYSE is open. If we receive your request prior to
that time,  your purchase  price will be the NAV per share  determined for that
day. If we receive  your  request  after the NAV per share is  calculated,  the
purchase will be effective on the next business day. If you plan to purchase

                                      10

Fund shares with a foreign check,  we suggest you convert your foreign check to
U.S.  dollars prior to investment in the Fund to avoid a potential delay in the
effective date of your purchase of up to four to six weeks. Furthermore, a bank
charge may be assessed in the clearing process, which will be deducted from the
amount of the purchase.

Redemption of Shares

You may redeem Fund shares by any of the methods described below on any day the
NAV per share is calculated.  Redemptions are effective on the day instructions
are received in a manner as  described  below.  However,  if  instructions  are
received  after  the NAV per share  calculation  (generally  4:00 p.m.  Eastern
Time), redemption will be effective on the next business day. 

Within seven days after the effective date of redemption, we will send you your
money. Payment for redemption of shares purchased by EFT or check is sent after
the EFT or check has cleared,  which could take up to 15 days from the purchase
date. If you are considering  redeeming shares soon after purchase,  you should
purchase by bank wire or certified check to avoid delay.

In  addition,  the  Company may elect to suspend  the  redemption  of shares or
postpone the date of payment in limited circumstances.

amount of $250 or more. Any checks written for less than $250 will be returned.
You will not be  charged  for the use of  checks  or any  subsequent  reorders.

not write a check to close your account. Remember, writing a check results in a
taxable event and is therefore  reportable for federal tax purposes.  

IMPORTANT INFORMATION ABOUT 
PURCHASES AND REDEMPTIONS

Investor's Guide to USAA Mutual Fund Services 

Upon your initial  investment with us, you will receive the INVESTOR'S GUIDE to
help you get the most out of your USAA mutual  fund  account and to help you in
your role as an investor.  In the INVESTOR'S  GUIDE,  you will find  additional
information on purchases,  redemptions,  and methods of payment.  You will also
find in-depth information on automatic investment plans, shareholder statements
and reports, and other useful information.

Account Balance

Beginning in September  1998,  and occurring each  September  thereafter,  USAA
Shareholder  Account Services (SAS),  the Fund's transfer agent,  will assess a
small balance account fee of $12 to each shareholder account with a balance, at
the time of assessment, of less than $2,000. The fee will reduce total transfer
agency fees paid by the Fund to SAS. Accounts exempt from the fee include:  (1)
any  account  regularly  purchasing  additional  shares  each month  through an
automatic  investment  plan;  (2) any  account  registered  under  the  Uniform
Gifts/Transfers to Minors Act (UGMA/UTMA);  (3) all (non-IRA) money market fund
accounts;  (4) any account whose registered  owner has an aggregate  balance of
$50,000 or more  invested in USAA mutual  funds;  and (5) all IRA accounts (for
the first year the account is open).

Company Rights 

The Company reserves the right to:

o    reject  purchase  or  exchange  orders  when in the best  interest  of the
     Company;

o    limit or  discontinue  the  offering  of  shares of any  portfolio  of the
     Company without notice to the shareholders;

o    impose a  redemption  charge of up to 1% of the net asset  value of shares
     redeemed  if  circumstances   indicate  a  charge  is  necessary  for  the
     protection of remaining investors (for example, if excessive market-timing
     share activity unfairly burdens  long-term  investors);  however,  this 1%
     charge will not be imposed  upon  shareholders  unless  authorized  by the
     Board of Directors and the required notice has been given to shareholders;

o    require a signature  guarantee for purchases,  redemptions,  or changes in
     account  information in those  instances  where the  appropriateness  of a
     signature  authorization  is in  question.  The  Statement  of  Additional
     Information contains information on acceptable guarantors;

o    redeem an account with less than 10 shares, with certain limitations.

EXCHANGES

Exchange Privilege

The exchange privilege is automatic when you complete your application. You may
exchange  shares  among Funds in the USAA Family of Funds,  provided you do not
hold these shares in stock  certificate  form and the shares to be acquired are
offered  in  your  state  of  residence.   The  Fund's   transfer   agent  will
simultaneously  process exchange  redemptions and purchases at the share prices
next  determined  after the exchange order is received.  For federal income tax
purposes,  an exchange  between Funds is a taxable event;  and as such, you may
realize a capital  gain or loss.  

The Fund has undertaken certain procedures regarding telephone  transactions as
described on page 12.

Exchange Limitations, Excessive Trading
   
To  minimize  Fund costs and to protect the Funds and their  shareholders  from
unfair expense burdens,  the Funds restrict excessive  exchanges.  The limit on
exchanges  out of any Fund in the USAA Family of Funds for each  account is six
per calendar  year (except  there is no  limitation on exchanges out of the Tax
Exempt Short-Term Fund,  Short-Term Bond Fund, or any of the money market funds
in the USAA Family of Funds).

SHAREHOLDER INFORMATION

Share Price Calculation

The price at which shareholders purchase and redeem Fund shares is equal to the
net asset  value  (NAV)  per  share  determined  on the  effective  date of the
purchase or  redemption.  You may buy and sell Fund shares at the NAV per share
without a sales charge.

When

When The Fund's NAV per share is calculated at the close of the regular trading
session of the NYSE, which is usually 4:00 p.m. Eastern Time.

How

The NAV per share is calculated by adding the value of all securities and other
assets in the Fund, deducting liabilities, and dividing by the number of shares
outstanding.

Dividends and Distributions

Net investment income is accrued daily and paid on the last business day of the
month.  Daily  dividends  are  declared  at the  time  the  NAV  per  share  is
calculated.  Dividends  shall  begin  accruing  on  shares  purchased  the  day
following the effective date and shall continue to accrue to the effective date
of redemption.  When you choose to receive cash dividends monthly, we will send
you those funds that have accrued  during the month after the payment date. Any
net capital  gain  distribution  usually  occurs  within 45 days of the July 31
fiscal year end, which would be somewhere  around the middle of September.  The
Fund will make additional payments to shareholders,  if necessary, to avoid the
imposition of any federal income or excise tax.
   
All  income  dividends  and  capital  gain   distributions   are  automatically
reinvested,  unless we receive different instructions from you. The share price
will be the NAV of the  Fund  shares  computed  on the  ex-dividend  date.  Any
capital gain distribution paid by the Fund will reduce the NAV per share by the
amount of the  distribution.  These dividends and  distributions are subject to
taxes.
    
We will invest any  dividend  or  distribution  payment  returned to us in your
account at the  then-current NAV per share.  Dividend and  distribution  checks
become  void six months  from the date on the  check.  The amount of the voided
check will be invested in your account at the then-current NAV per share.

                                      15

Federal Taxes

This tax  information  is quite  general and refers to the  federal  income tax
provisions in effect as of the date of this Prospectus.  Note that the recently
enacted Taxpayer Relief Act of 1997 and regulations that will likely be created
to  implement   the  Act  may  affect  the  status  and  treatment  of  certain
distributions  shareholders  receive from the Fund. We urge you to consult your
own tax  adviser  about the status of  distributions  from the Fund in your own
state  and  locality.  

FUND - The Fund  intends to qualify as a  regulated  investment  company  (RIC)
under Subchapter M of the Internal Revenue Code of 1986, as amended.  As a RIC,
the Fund will not be subject to federal income tax on its net investment income
and net capital gains distributed to shareholders.  Net capital gains are those
gains in excess of capital  losses.  

SHAREHOLDER - Dividends from taxable net investment income and distributions of
net short-term  capital gains are taxable to shareholders  as ordinary  income,
whether received in cash or reinvested in additional shares.  

Regardless  of the length of time you have held the Fund shares,  distributions
of net long-term  capital gains are taxable as long-term  capital gains whether
received in cash or reinvested in additional shares.  

Redemptions  and  exchanges  are subject to income tax based on the  difference
between  the  cost of  shares  when  purchased  and  the  price  received  upon
redemption or exchange. 

WITHHOLDING  - Federal law  requires the Fund to withhold and remit to the U.S.
Treasury a portion of the income dividends and capital gain  distributions  and
proceeds of redemptions paid to any non-corporate shareholder who:

o  fails to furnish the Fund with a correct tax identification number,  
o  underreports dividend or interest income, or 
o  fails to certify that he or she is not subject to withholding. 

To avoid this withholding requirement, you must certify on your application, or
on a separate  Form W-9 supplied by the Fund's  transfer  agent,  that your tax
identification  number is correct and you are not  currently  subject to backup
withholding.

REPORTING - The Fund will report annually to you information concerning the tax
status of dividends and distributions for federal income tax purposes.

                                      16

DESCRIPTION OF SHARES 

The Fund is a series of USAA Mutual Fund,  Inc.  (Company) and is  diversified.
The Company is an open-end management investment company incorporated under the
laws of the State of  Maryland.  The Company is  authorized  to issue shares of
common  stock of separate  series,  each of which is commonly  referred to as a
mutual fund. There are ten mutual funds in the Company, including this Fund.
   
The Company does not hold annual or regular  meetings of shareholders and holds
special  meetings only as required by the  Investment  Company Act of 1940. The
Directors  may fill  vacancies  on the Board or appoint  new  Directors  if the
result is that at least  two-thirds of the Directors have still been elected by
shareholders.  Shareholders have one vote per share (with proportionate  voting
for  fractional  shares)  regardless  of the  relative  net asset  value of the
shares. If a matter affects an individual fund in the Company,  there will be a
separate  vote  of  the  shareholders  of  that  specific  fund.   Shareholders
collectively  holding at least 10% of the outstanding shares of the Company may
request a  shareholder  meeting at any time for the purpose of voting to remove
one or more of the Directors. The Company will assist in communicating to other
shareholders about the meeting.

                                   APPENDIX A

THE FOLLOWING ARE DESCRIPTIONS OF CERTAIN TYPES OF SECURITIES IN WHICH WE MAY
INVEST THE FUND'S ASSETS:  

PUT BONDS 
We may invest in securities (including securities with variable interest rates)
which may be  redeemed  or sold back (put) to the issuer of the  security  or a
third party prior to stated maturity (put bonds). Such securities will normally
trade as if maturity is the earlier put date,  even though  stated  maturity is
longer. 

VARIABLE RATE SECURITIES 
We may invest in  securities  that bear  interest at rates  which are  adjusted
periodically to market rates.

o    These  interest  rate  adjustments  can both  raise and  lower the  income
     generated by such  securities.  These changes will have the same effect on
     the  income  earned  by the  Fund  depending  on the  proportion  of  such
     securities held.

o    The value of variable rate  securities is less affected than  fixed-coupon
     securities by changes in prevailing interest rates because of the periodic
     adjustment  of their  coupons to a market  rate.  The  shorter  the period
     between adjustments,  the smaller the impact of interest rate fluctuations
     on the value of these securities.

o    The market  value of a variable  rate  security  usually  tends toward par
     (100% of face value) at interest rate adjustment time.

WHEN-ISSUED SECURITIES 
We may invest in new issues of debt securities offered on a when-issued basis.

o    Delivery  and  payment  take  place  after the date of the  commitment  to
     purchase,  normally within 45 days. Both price and interest rate are fixed
     at the time of commitment.

o    The Fund does not earn interest on the securities  until  settlement,  and
     the market value of the  securities  may  fluctuate  between  purchase and
     settlement.

o    Such securities can be sold before settlement date.

REPURCHASE AGREEMENTS 
We may invest in repurchase  agreements which are collateralized by obligations
issued   or   guaranteed   by  the   U.S.   Government,   its   agencies,   and
instrumentalities.  A repurchase agreement is a transaction in which a security
is purchased  with a  simultaneous  commitment to sell it back to the seller (a
commercial bank or recognized  securities dealer) at an agreed upon price on an
agreed  upon date.  This date is usually not more than seven days from the date
of purchase.  The resale price  reflects the purchase price plus an agreed upon
market rate of  interest,  which is unrelated to the coupon rate or maturity of
the purchased security.  

MUNICIPAL LEASE OBLIGATIONS
We may invest in  a variety  of  instruments  referred  to  as  muncipal  lease
obligations, including:

o    Leases,
o    Installment purchase contracts, and 
o    Certificates of participation in such leases and contracts.

                                      18
<PAGE>

MORTGAGE-BACKED AND ASSET-BACKED SECURITIES
We may invest the Fund's assets in mortgage-backed and asset-backed securities.
Mortgage-backed  securities include,  but are not limited to, securities issued
by the  Government  National  Mortgage  Association  (Ginnie Mae),  the Federal
National Mortgage  Association  (Fannie Mae) and the Federal Home Loan Mortgage
Corporation  (Freddie Mac). These securities  represent  ownership in a pool of
mortgage loans. They differ from  conventional  bonds in that principal is paid
back to the  investor as payments are made on the  underlying  mortgages in the
pool.  Accordingly,  the Fund receives monthly scheduled  payments of principal
and interest along with any unscheduled principal prepayments on the underlying
mortgages.  Because these scheduled and unscheduled  principal payments must be
reinvested  at prevailing  interest  rates,  mortgage-backed  securities do not
provide  an  effective  means of locking in  long-term  interest  rates for the
investor.  Like other fixed income  securities,  when interest  rates rise, the
value of a  mortgage-backed  security  generally  will decline;  however,  when
interest  rates are declining,  the value of  mortgage-backed  securities  with
prepayment features may not increase as much as other fixed income securities.

Mortgage-backed  securities also include  collateralized  mortgage  obligations
(CMOs).  CMOs are obligations fully  collateralized by a portfolio of mortgages
or  mortgage-related  securities.  CMOs are divided into pieces (tranches) with
varying maturities.  The cash flow from the underlying mortgages is used to pay
off each tranche  separately.  CMOs are designed to provide investors with more
predictable maturities than regular mortgage securities but such maturities can
be  difficult  to  predict  because of the  effect of  prepayments.  Failure to
accurately predict  prepayments can adversely affect the Fund's return on these
investments. CMOs may also be less marketable than other securities.

Asset-backed  securities  represent a  participation  in, or are secured by and
payable  from, a stream of payments  generated by  particular  assets,  such as
credit card,  motor vehicle,  or trade  receivables.  They may be  pass-through
certificates,  which  have  characteristics  very  similar  to  mortgage-backed
securities,  discussed  above.  They may  also be in the  form of  asset-backed
commercial paper, which is issued by a special purpose entity, organized solely
to issue the  commercial  paper and to purchase  interests  in the assets.  The
credit quality of these  securities  depends  primarily upon the quality of the
underlying assets and the level of credit support and enhancement provided.

The weighted  average  life of such  securities  is likely to be  substantially
shorter  than their stated  final  maturity as a result of scheduled  principal
payments and unscheduled principal prepayments.

EURODOLLAR AND YANKEE OBLIGATIONS 
We may invest a portion of the Fund's assets in dollar-denominated  instruments
that have been issued outside the U.S. capital markets by foreign  corporations
and financial  institutions  and by foreign  branches of U.S.  corporations and
financial institutions  (Eurodollar) as well as dollar-denominated  instruments
that have been issued by foreign issuers in the U.S. capital markets  (Yankee).
In addition,  we may invest a portion of the Fund's  assets in  Eurodollar  and
Yankee obligations of investment-grade emerging market countries. 

MASTER DEMAND NOTES
We may invest the Fund's assets in master demand notes,  which are  obligations
that permit the investment of fluctuating amounts by the Fund, at varying rates
of interest  using direct  arrangements  between the Fund,  as lender,  and the
borrower.  These notes permit daily changes in the amounts  borrowed.  The Fund
has the right to increase  the amount under the note at any time up to the full
amount  provided  by the note  agreement,  or to decrease  the amount,  and the
borrower  may  repay  up to the  full  amount  of  the  note  without  penalty.
Frequently, such obligations are secured by

                                      19
<PAGE>

letters  of credit or other  credit  support  arrangements  provided  by banks.
Because master demand notes are direct lending  arrangements between the lender
and  borrower,  these  instruments  generally  will not be  traded,  and  there
generally is no secondary market for these notes,  although they are redeemable
(and  immediately  repayable  by the  borrower)  at face  value,  plus  accrued
interest,  at any time. We will invest the Fund's assets in master demand notes
only if the Board of Directors or its delegate has determined  that they are of
credit  quality  comparable to the debt  securities in which the Fund generally
may invest.  

ILLIQUID SECURITIES 
We may not invest more than 15% of the market value of the Fund's net assets in
securities  which are illiquid.  Illiquid  securities are those securities that
cannot be disposed of in the ordinary  course of business in seven days or less
at approximately the value at which the Fund has valued the securities.

                                December 1, 1997

The  Fund is a  no-load  mutual  fund  offered  by USAA  Investment  Management
Company.  USAA will seek the highest income  consistent  with  preservation  of
capital  and  maintenance  of  liquidity  by  investing  in  high-quality  debt
instruments  with  maturities  of 397  days  or  less.  USAA  will  maintain  a
dollar-weighted average portfolio maturity of 90 days or less and will endeavor
to maintain a constant net asset value per share of $1.

SHARES OF THIS FUND ARE NOT DEPOSITS OR OTHER OBLIGATIONS OF, OR GUARANTEED BY,
THE USAA  FEDERAL  SAVINGS  BANK,  ARE NOT  INSURED  BY THE  FDIC OR ANY  OTHER
GOVERNMENT AGENCY, ARE SUBJECT TO INVESTMENT RISKS, AND MAY LOSE VALUE.

AS WITH  OTHER  MUTUAL  FUNDS,  THESE  SECURITIES  HAVE  NOT BEEN  APPROVED  OR
DISAPPROVED  BY THE SECURITIES  AND EXCHANGE  COMMISSION  (SEC) NOR HAS THE SEC
PASSED UPON THE ACCURACY OR ADEQUACY OF THIS PROSPECTUS.  ANY REPRESENTATION TO
THE CONTRARY IS A CRIMINAL OFFENSE.

AN  INVESTMENT  IN THE  FUND IS  NEITHER  INSURED  NOR  GUARANTEED  BY THE U.S.
GOVERNMENT AND THERE CAN BE NO ASSURANCE THAT THE FUND WILL BE ABLE TO MAINTAIN
A STABLE NET ASSET VALUE OF $1 PER SHARE.

THIS PROSPECTUS  CONTAINS  INFORMATION YOU SHOULD KNOW BEFORE YOU INVEST IN THE
FUND. PLEASE READ IT AND KEEP IT FOR FUTURE REFERENCE.

WHO MANAGES THE FUND?

USAA Investment  Management Company manages the Fund. For easier reading,  USAA
Investment  Management  Company  will be  referred  to as "we"  throughout  the
Prospectus.

WHAT IS THE INVESTMENT OBJECTIVE?

The  Fund's  investment   objective  is  the  highest  income  consistent  with
preservation of capital and the maintenance of liquidity.  See FUND INVESTMENTS
on page 5 for more information.

HOW DOES THIS FUND DIFFER
FROM A SAVINGS ACCOUNT?

As you know, a savings  account is a deposit with a bank. The bank is obligated
to return  the amount  deposited  and to pay you  interest  for the use of your
money.  Up to a certain  amount,  the FDIC will  insure that the bank meets its
obligations.  The Fund is not a savings account but, rather,  is a money market
mutual  fund that  issues  and  redeems  its shares at the Fund's per share net
asset value  (NAV).  The Fund always seeks to maintain a constant NAV of $1 per
share. Unlike a savings account,  the shares are not insured by the FDIC or any
other governmental agency and there can be no assurance that shares will always
be valued at $1 per share.  We manage the Fund,  however,  in  accordance  with
strict SEC guidelines  designed to result in the value of your shares remaining
at $1 per  share.  Just  as a  savings  account  pays  interest  on the  amount
deposited,  the Fund pays  dividends on the shares you own. If these  dividends
are reinvested in the Fund, the value of your account will grow over time.

IS THIS FUND FOR YOU? 

THIS FUND MIGHT BE APPROPRIATE AS PART OF YOUR INVESTMENT PORTFOLIO IF . . . 

o  You need your money back within a short period.
o  You need to preserve principal.
o  You want a low-risk investment.

THIS FUND MAY NOT BE APPROPRIATE AS PART OF YOUR INVESTMENT PORTFOLIO IF . . .

o  You need a high total return to achieve your goals.
o  You need an investment that provides tax-free income. 
   
If you feel this Fund is not the one for you,  refer to page 19 for a  complete
list of the USAA Family of No-Load Mutual Funds.

HOW DO YOU BUY?
   
You may make your initial investment directly by mail, in person or, in certain
instances,  by telephone.  Generally,  the minimum initial investment is $3,000
[$500 for Uniform  Gifts/Transfers to Minors Act (UGMA/UTMA)  accounts and $250
for IRAs] and can be made by check or by wire. If you participate in one of our
automatic  investment plans, your minimum initial investment may be less. There
is more information about how to purchase Fund shares on page 9.
    
FEES AND EXPENSES

This summary  shows what it will cost you directly or  indirectly  to invest in
the Fund.

Shareholder Transaction Expenses -- Fees You Pay Directly

There are no fees  charged to your  account  when you buy,  sell,  or hold Fund
shares.  However,  if you sell shares and request your money by wire  transfer,
you will pay a $10 fee. (Your bank may also charge a fee for receiving wires.)

Annual Fund Operating Expenses -- Fees You Pay Indirectly

Fund  expenses  come out of the Fund's  assets and are  reflected in the Fund's
share price and dividends.  "Other Expenses" include expenses such as custodian
and transfer agent fees. The figures below show actual  expenditures during the
past fiscal year ended July 31, 1997,  and are  calculated  as a percentage  of
average net assets (ANA).

              Management Fees (net of              
               reimbursement)                     .20%        12b-1 FEES -

              Total Fund Operating Expenses                   SELLING FUND  
              (net of reimbursement)              .45%        SHARES.
                                                  ====

During the year, we voluntarily  limited the Fund's annual  expenses to .45% of
its ANA and reimbursed the Fund for all expenses in excess of this  limitation.
The  Management  Fees and Total Fund Operating  Expenses  reflect these expense
reimbursements. Without these reimbursements, the amount of the Management Fees
and Total Fund Operating  Expenses as a percentage of the Fund's ANA would have
been .24% and .49%, respectively. We have again voluntarily agreed to limit the
Fund's annual  expenses to .45% of its ANA and will  reimburse the Fund for all
expenses in excess of that amount until December 1, 1998.

                                       3

Example of Effect of Fund Operating Expenses

You  would  pay the  following  expenses  on a $1,000  investment  in the Fund,
assuming  (1) 5% annual  return and (2)  redemption  at the end of the  periods
shown.

               1 year................................... $   5

You may see the Fund's yield or effective  yield quoted in  advertisements  and
reports.  All mutual funds must use the same  formulas to  calculate  yield and
effective yield.  Yield is annualized net income of the Fund during a specified
seven-day period as a percentage of the Fund's share price. The effective yield
is calculated in a similar way; however, when annualized,  the income earned is
assumed to be reinvested.  The effective yield will be slightly higher than the
yield because of the compounding  effect of the assumed  reinvestment.  You may
also see a comparison of the Fund's  performance  to that of other mutual funds
with similar investment objectives and to relevant indexes.

FUND INVESTMENTS

Investment Policies and Risks

   Q   What is the Fund's investment policy?

   A   We   will   invest   the   Fund's   assets   in    high-quality,    U.S.
       dollar-denominated debt securities of domestic and foreign issuers which
       have been determined to present minimal credit risk.

   Q   What  type of  money  market  instruments  are  included  in the  Fund's
       portfolio?

   A   The Fund's portfolio may include the following:

       o  Obligations    of   the   U.S.    Government,    its   agents,    and
          instrumentalities,  and repurchase agreements  collateralized by such
          obligations;
       o  Short-term  corporate  debt  obligations  such as notes,  bonds,  and
          commercial paper;
       o  U.S.  bank or foreign bank  obligations,  including  certificates  of
          deposit, banker's acceptances, and time deposits;
       o  Obligations  of state and local  governments  and their  agencies and
          instrumentalities;
       o  Municipal lease obligations;
       o  Mortgage-backed securities;
       o  Asset-backed securities;
       o  Master demand notes;
       o  Eurodollar obligations;
       o  Yankee obligations;
       o  Other short-term debt securities.
   
       Further  description of these  securities is found in APPENDIX A on page
       17.
    
   Q   Are there any limits on how much we can invest in one issuer?

   A   Yes.  The SEC has set  certain  diversification  requirements  for money
       market funds. Generally,  these requirements limit a money market fund's
       investments in securities of any issuer to no more than 5% of the fund's
       assets, excluding securities issued or guaranteed by the U.S. Government
       or its agencies and instrumentalities.

<PAGE>

   Q   What are the credit ratings of the Fund's investments?

   A   We  will  purchase  only   high-quality   securities   that  qualify  as
       "first-tier"  securities  under the SEC rules that apply to money market
       funds. In general,  a first-tier  security is defined as a security that
       is:

       o issued  or  guaranteed  by  the  U.S.  Government  or  any  agency  or
         instrumentality thereof;

       o rated in the highest  category for  short-term  securities by at least
         two Nationally Recognized  Statistical Rating Organizations  (NRSROs),
         or by one NRSRO if the security is rated by only one NRSRO;
      
       o unrated but issued by an issuer that has other  comparable  short-term
         obligations so rated; or
       
       o unrated but we have determined it to be of comparable quality.

   Q   Who  are  considered  to be  Nationally  Recognized  Statistical  Rating
       Organizations?

   A   Current NRSROs include:

       o  Moody's Investors Service, Inc.;
       o  Standard & Poor's Ratings Group;
       o  Fitch Investors Services, Inc.;
       o  Duff & Phelps Inc.;
       o  Thompson BankWatch, Inc.; and
       o  IBCA Inc.

   Q   What happens if the rating of a security is downgraded?

   A   If the  rating of a  security  is  downgraded  after  purchase,  we will
       determine whether it is in the best interest of the Fund's  shareholders
       to continue to hold the security in the Fund's portfolio.

   Q   Will the Fund always maintain a net asset value of $1 per share?

   A   While we will endeavor to maintain a constant Fund net asset value of $1
       per  share,  there  is no  assurance  that  we  will  be  able to do so.
       Remember,  the shares are  neither  insured nor  guaranteed  by the U.S.
       Government.  As such, the Fund carries some risk. For example,  there is
       always a risk that the issuer of a  security  held by the Fund will fail
       to pay  interest or  principal  when due.  We attempt to  minimize  this
       credit risk by investing only in securities rated in the highest

                                       6
<PAGE>

       category for  short-term  securities,  or, if not rated,  of  comparable
       quality at the time of  purchase.  In  addition,  we will not purchase a
       security unless our analysts have determined that the security  presents
       minimal credit risk.There is also a risk that rising interest rates will
       cause the value of the  Fund's  securities  to  decline.  We  attempt to
       minimize  this  interest  risk by limiting the maturity of each security
       and maintaining an average weighted  maturity for the Fund of 90 days or
       less.
   
For additional  information  about other  securities in which we may invest the
Fund's assets, see APPENDIX A on page 17.
    
Investment Restrictions

The following restrictions may only be changed with shareholder approval:

o    The Fund may not invest more than 25% of its total assets in one industry.
     For the  purpose  of  this  policy,  banks  are not  considered  a  single
     industry.

o    The Fund may borrow only for temporary or emergency  purposes in an amount
     not exceeding 33 1/3% of its total assets.

You will find a complete listing of the precise investment  restrictions in the
Fund's Statement of Additional Information.

USING MUTUAL FUNDS IN AN
INVESTMENT PROGRAM

I. The Idea Behind Mutual Funds

Mutual funds provide small investors some of the advantages  enjoyed by wealthy
investors.  A  relatively  small  investment  can  buy  part  of a  diversified
portfolio. That portfolio is managed by investment professionals, relieving you
of the  need to make  individual  stock  or bond  selections.  You  also  enjoy
conveniences,  such as daily  pricing,  liquidity,  and in the case of the USAA
Family of Funds, no sales charge. The portfolio, because of its size, has lower
transaction  costs on its trades than most individuals would have. As a result,
you own an investment  that in earlier times would have been  available only to
very wealthy people.

II. Using Funds in an Investment Program

In  choosing a mutual  fund as an  investment  vehicle,  you are giving up some
investment decisions,  but must still make others. The decisions you don't have
to make are those involved with choosing individual securities. We will perform
that function.  In addition, we will arrange for the safekeeping of securities,
auditing the annual financial  statements,  and daily valuation of the Fund, as
well as other functions.

                                       8
<PAGE>

You,  however,  retain  at  least  part of the  responsibility  for an  equally
important  decision.  This decision involves  determining a portfolio of mutual
funds that balances your  investment  goals with your tolerance for risk. It is
likely that this decision may include the use of more than one fund of the USAA
Family of Funds.

For example, assume you wish to invest in a widely-diversified  portfolio.  You
could combine an investment in the Money Market Fund with  investments in other
mutual  funds  that  invest  in  stocks  of  large  and  small   companies  and
high-dividend  stocks.  This is just one way you could  combine  funds that fit
your own risk and reward goals.

III. USAA's Family of Funds
   
We offer you another  alternative for asset  allocation with our asset strategy
funds  listed on page 19. These unique  mutual funds  provide a  professionally
managed  diversified  investment  portfolio  within  a  mutual  fund.  They are
designed  for the  individual  who  prefers to  delegate  the asset  allocation
process to an investment manager and are structured to achieve  diversification
across a number of investment categories.
    
Whether you prefer to create  your own mix of mutual  funds or use a USAA Asset
Strategy  Fund,  the USAA  Family of Funds  provides  a broad  range of choices
covering  just  about  any   investor's   investment   objectives.   Our  sales
representatives  stand  ready to assist you with your  choices  and to help you
craft a portfolio which meets your needs.

HOW TO INVEST

Purchase of Shares

OPENING AN ACCOUNT
   
You may open an account and make an investment  as described  below by mail, in
person,  bank wire,  electronic  funds  transfer  (EFT),  or phone. A complete,
signed  application  is  required  for each new  account.  
    
TAX ID NUMBER  
Each shareholder  named on the account must provide a social security number or
tax identification number to avoid possible withholding requirements.

EFFECTIVE DATE 
When you make a purchase, your purchase price will be the net asset value (NAV)
per share next  determined  after we  receive  your  request in proper  form as
described  below.  The Fund's  NAV is  determined  at the close of the  regular
trading  session  (generally  4:00  p.m.  Eastern  Time) of the New York  Stock
Exchange  (NYSE) each day the NYSE is open. If we receive your request prior to
that time, your purchase price will be the NAV

                                       9
<PAGE>

per share determined for that day. If we receive your request after the NAV per
share is  calculated,  the purchase will be effective on the next business day.
If you plan to  purchase  Fund  shares  with a foreign  check,  we suggest  you
convert your foreign  check to U.S.  dollars prior to investment in the Fund to
avoid a potential delay in the effective date of your purchase of up to four to
six weeks. Furthermore,  a bank charge may be assessed in the clearing process,
which will be deducted from the amount of the purchase.

Redemption of Shares

Within seven days after the effective date of redemption, we will send you your
money. Payment for redemption of shares purchased by EFT or check is sent after
the EFT or check has cleared,  which could take up to 15 days from the purchase
date. If you are considering  redeeming shares soon after purchase,  you should
purchase by bank wire or certified check to avoid delay.

In  addition,  the  Company may elect to suspend  the  redemption  of shares or
postpone the date of payment in limited circumstances.

Account Balance

Beginning in September  1998,  and occurring each  September  thereafter,  USAA
Shareholder  Account Services (SAS),  the Fund's transfer agent,  will assess a
small balance account fee of $12 to each shareholder account with a balance, at
the time of assessment, of less than $2,000. The fee will reduce total transfer
agency fees paid by the Fund to SAS. Accounts exempt from the fee include:  (1)
any  account  regularly  purchasing  additional  shares  each month  through an
automatic  investment  plan;  (2) any  account  registered  under  the  Uniform
Gifts/Transfers to Minors Act (UGMA/UTMA);  (3) all (non-IRA) money market fund
accounts;  (4) any account whose registered  owner has an aggregate  balance of
$50,000 or more  invested in USAA mutual  funds;  and (5) all IRA accounts (for
the first year the account is open).

Company Rights The Company reserves the right to:

o   reject  purchase  or  exchange  orders  when in the  best  interest  of the
    Company;

o   limit or discontinue the offering of shares of any portfolio of the Company
    without notice to the shareholders;

o   impose a  redemption  charge of up to 1% of the net  asset  value of shares
    redeemed if circumstances indicate a charge is necessary for the protection
    of remaining  investors  (for  example,  if excessive  market-timing  share
    activity unfairly burdens  long-term  investors);  however,  this 1% charge
    will not be imposed upon  shareholders  unless  authorized  by the Board of
    Directors and the required notice has been given to shareholders;

o   require a signature  guarantee for  purchases,  redemptions,  or changes in
    account  information  in those  instances  where the  appropriateness  of a
    signature  authorization  is  in  question.  The  Statement  of  Additional
    Information contains information on acceptable guarantors;

o   redeem an account with less than 500 shares, with certain limitations.

EXCHANGES

Exchange Privilege

The exchange privilege is automatic when you complete your application. You may
exchange  shares  among Funds in the USAA Family of Funds,  provided you do not
hold these shares in stock  certificate  form and the shares to be acquired are
offered  in  your  state  of  residence.   The  Fund's   transfer   agent  will
simultaneously  process exchange  redemptions and purchases at the share prices
next  determined  after the exchange order is received.  For federal income tax
purposes,  an exchange  between Funds is a taxable event;  and as such, you may
realize a capital gain or loss.  

                                      13

The Fund has undertaken certain procedures regarding telephone  transactions as
described on page 12.
    
Exchange Limitations, Excessive Trading
   
To  minimize  Fund costs and to protect the Funds and their  shareholders  from
unfair expense burdens,  the Funds restrict excessive  exchanges.  The limit on
exchanges  out of any Fund in the USAA Family of Funds for each  account is six
per calendar  year (except  there is no  limitation on exchanges out of the Tax
Exempt Short-Term Fund,  Short-Term Bond Fund, or any of the money market funds
in the USAA Family of Funds). 
    
SHAREHOLDER INFORMATION

Share Price Calculation

The price at which shareholders purchase and redeem Fund shares is equal to the
net asset  value  (NAV)  per  share  determined  on the  effective  date of the
purchase or  redemption.  You may buy and sell Fund shares at the NAV per share
without a sales charge.

When 

The  Fund's NAV per share is  calculated  at the close of the  regular  trading
session of the NYSE, which is usually 4:00 p.m. Eastern Time.

How

The NAV per share is calculated by adding the value of all securities and other
assets in the Fund, deducting liabilities, and dividing by the number of shares
outstanding.

Dividends and Distributions

Net investment income is accrued daily and paid on the last business day of the
month.  Daily  dividends  are  declared  at the  time  the  NAV  per  share  is
calculated.  Dividends  shall  begin  accruing  on  shares  purchased  the  day
following the effective date and shall continue to accrue to the effective date
of redemption.  When you choose to receive cash dividends monthly, we will send
you those funds that have accrued during the month after the payment date.

We will invest any  dividend  or  distribution  payment  returned to us in your
account at the  then-current NAV per share.  Dividend and  distribution  checks
become  void six months  from the date on the  check.  The amount of the voided
check will be invested in your account at the then-current NAV per share.

                                      14

Federal Taxes

This tax  information  is quite  general and refers to the  federal  income tax
provisions in effect as of the date of this Prospectus.  Note that the recently
enacted Taxpayer Relief Act of 1997 and regulations that will likely be created
to  implement   the  Act  may  affect  the  status  and  treatment  of  certain
distributions  shareholders  receive from the Fund. We urge you to consult your
own tax  adviser  about the status of  distributions  from the Fund in your own
state and locality.

FUND - The Fund  intends to qualify as a  regulated  investment  company  (RIC)
under Subchapter M of the Internal Revenue Code of 1986, as amended.  As a RIC,
the Fund will not be subject to federal income tax on its net investment income
and net capital gains distributed to shareholders.  Net capital gains are those
gains in excess of capital losses.

SHAREHOLDER - Dividends from taxable net investment income and distributions of
net short-term  capital gains are taxable to shareholders  as ordinary  income,
whether received in cash or reinvested in additional shares.

Regardless  of the length of time you have held the Fund shares,  distributions
of net long-term  capital gains are taxable as long-term  capital gains whether
received in cash or reinvested in additional shares.  

WITHHOLDING  - Federal law  requires the Fund to withhold and remit to the U.S.
Treasury a portion of the income dividends and capital gain  distributions  and
proceeds of redemptions paid to any non-corporate shareholder who:

o    fails to furnish the Fund with a correct tax identification number,  
o    underreports dividend or interest income, or 
o    fails to certify that he or she is not subject to withholding. 

To avoid this withholding requirement, you must certify on your application, or
on a separate  Form W-9 supplied by the Fund's  transfer  agent,  that your tax
identification  number is correct and you are not  currently  subject to backup
withholding.

REPORTING - The Fund will report annually to you information concerning the tax
status of dividends and distributions for federal income tax purposes.

                                      15

DESCRIPTION OF SHARES

The Fund is a series of USAA Mutual Fund,  Inc.  (Company) and is  diversified.
The Company is an open-end management investment company incorporated under the
laws of the State of  Maryland.  The Company is  authorized  to issue shares of
common  stock of separate  series,  each of which is commonly  referred to as a
mutual fund. There are ten mutual funds in the Company, including this Fund.
   
The Company does not hold annual or regular  meetings of shareholders and holds
special  meetings only as required by the  Investment  Company Act of 1940. The
Directors  may fill  vacancies  on the Board or appoint  new  Directors  if the
result is that at least  two-thirds of the Directors have still been elected by
shareholders.  Shareholders have one vote per share (with proportionate  voting
for  fractional  shares)  regardless  of the  relative  net asset  value of the
shares. If a matter affects an individual fund in the Company,  there will be a
separate  vote  of  the  shareholders  of  that  specific  fund.   Shareholders
collectively  holding at least 10% of the outstanding shares of the Company may
request a  shareholder  meeting at any time for the purpose of voting to remove
one or more of the Directors. The Company will assist in communicating to other
shareholders about the meeting.

                                   APPENDIX A

THE FOLLOWING ARE  DESCRIPTIONS  OF CERTAIN TYPES OF SECURITIES IN WHICH WE MAY
INVEST THE FUND'S ASSETS:  

PUT BONDS
We may invest in securities (including securities with variable interest rates)
which may be  redeemed  or sold back (put) to the issuer of the  security  or a
third party prior to stated maturity (put bonds). Such securities will normally
trade as if maturity is the earlier put date,  even though  stated  maturity is
longer. 

VARIABLE RATE SECURITIES  
We may invest in  securities  that bear  interest at rates  which are  adjusted
periodically to market rates.

o    These  interest  rate  adjustments  can both  raise and  lower the  income
     generated by such  securities.  These changes will have the same effect on
     the  income  earned  by the  Fund  depending  on the  proportion  of  such
     securities held. 

o    The value of variable rate  securities is less affected than  fixed-coupon
     securities by changes in prevailing interest rates because of the periodic
     adjustment  of their  coupons to a market  rate.  The  shorter  the period
     between adjustments,  the smaller the impact of interest rate fluctuations
     on the value of these securities.

o    The market  value of a variable  rate  security  usually  tends toward par
     (100% of face value) at interest rate adjustment time.

WHEN-ISSUED SECURITIES
We may invest in new issues of debt securities offered on a when-issued basis.

o    Delivery  and  payment  take  place  after the date of the  commitment  to
     purchase,  normally within 45 days. Both price and interest rate are fixed
     at the time of commitment.  

o    The Fund does not earn interest on the securities  until  settlement,  and
     the market value of the  securities  may  fluctuate  between  purchase and
     settlement. 

o    Such securities can be sold before settlement date.

REPURCHASE AGREEMENTS  
We may invest in repurchase  agreements which are collateralized by obligations
issued   or   guaranteed   by  the   U.S.   Government,   its   agencies,   and
instrumentalities.  A repurchase agreement is a transaction in which a security
is purchased  with a  simultaneous  commitment to sell it back to the seller (a
commercial bank or recognized  securities dealer) at an agreed upon price on an
agreed  upon date.  This date is usually not more than seven days from the date
of purchase.  The resale price  reflects the purchase price plus an agreed upon
market rate of  interest,  which is unrelated to the coupon rate or maturity of
the purchased security.

MUNICIPAL LEASE OBLIGATIONS
We may invest in a variety of  instruments  commonly  referred to as  municipal
lease obligations, including: 

o    Leases, 
o    Installment purchase contracts, and 
o    Certificates of participation in such leases and contracts.

                                      17

EURODOLLAR AND YANKEE OBLIGATIONS 
We may invest a portion of the Fund's assets in dollar-denominated  instruments
that have been issued outside the U.S. capital markets by foreign  corporations
and financial  institutions  and by foreign  branches of U.S.  corporations and
financial institutions  (Eurodollar) as well as dollar-denominated  instruments
that have been issued by foreign issuers in the U.S. capital markets  (Yankee).
In addition,  we may invest a portion of the Fund's  assets in  Eurodollar  and
Yankee obligations of investment-grade emerging market countries.

MORTGAGE-BACKED AND ASSET-BACKED SECURITIES
We may invest the Fund's assets in mortgage-backed and asset-backed securities.
Mortgage-backed  securities include,  but are not limited to, securities issued
by the  Government  National  Mortgage  Association  (Ginnie Mae),  the Federal
National Mortgage  Association  (Fannie Mae) and the Federal Home Loan Mortgage
Corporation  (Freddie Mac). These securities  represent  ownership in a pool of
mortgage loans. They differ from  conventional  bonds in that principal is paid
back to the  investor as payments are made on the  underlying  mortgages in the
pool.  Accordingly,  the Fund receives monthly scheduled  payments of principal
and interest along with any unscheduled principal prepayments on the underlying
mortgages.  Because these scheduled and unscheduled  principal payments must be
reinvested  at prevailing  interest  rates,  mortgage-backed  securities do not
provide  an  effective  means of locking in  long-term  interest  rates for the
investor.  Like other fixed income  securities,  when interest  rates rise, the
value of a  mortgage-backed  security  generally  will decline;  however,  when
interest  rates are declining,  the value of  mortgage-backed  securities  with
prepayment features may not increase as much as other fixed income securities.

Asset-backed  securities  represent a  participation  in, or are secured by and
payable  from, a stream of payments  generated by  particular  assets,  such as
credit card,  motor vehicle,  or trade  receivables.  They may be  pass-through
certificates,  which  have  characteristics  very  similar  to  mortgage-backed
securities,  discussed  above.  They may  also be in the  form of  asset-backed
commercial paper, which is issued by a special purpose entity, organized solely
to issue the  commercial  paper and to purchase  interests  in the assets.  The
credit quality of these  securities  depends  primarily upon the quality of the
underlying assets and the level of credit support and enhancement provided.

MASTER DEMAND NOTES 
We may invest the Fund's assets in master demand notes,  which are  obligations
that permit the investment of fluctuating amounts by the Fund, at varying rates
of interest  using direct  arrangements  between the Fund,  as lender,  and the
borrower.  These notes permit daily changes in the amounts  borrowed.  The Fund
has the right to increase  the amount under the note at any time up to the full
amount  provided  by the note  agreement,  or to decrease  the amount,  and the
borrower  may  repay  up to the  full  amount  of  the  note  without  penalty.
Frequently,  such  obligations are secured by letters of credit or other credit
support arrangements  provided by banks. Because master demand notes are direct
lending  arrangements  between  the  lender  and  borrower,  these  instruments
generally will not be traded,  and there  generally is no secondary  market for
these notes,  although they are redeemable  (and  immediately  repayable by the
borrower) at face value, plus accrued interest, at any time. We will invest the
Fund's  assets in master  demand  notes only if the Board of  Directors  or its
delegate has determined that they are of credit quality  comparable to the debt
securities in which the Fund generally may invest.  

ILLIQUID SECURITIES 
We may not invest more than 10% of the market value of the Fund's net assets in
securities  which are illiquid.  Illiquid  securities are those securities that
cannot be disposed of in the ordinary  course of business in seven days or less
at approximately the value at which the Fund has valued the securities.

                            VALUATION OF SECURITIES

Shares of each Fund are offered on a continuing best efforts basis through USAA
Investment  Management  Company (IMCO or the Manager).  The offering  price for
shares of each Fund is equal to the  current  net asset  value (NAV) per share.
The NAV per share of each  Fund is  calculated  by adding  the value of all its
portfolio securities and other assets, deducting its liabilities,  and dividing
by the number of shares outstanding.  

     A Fund's NAV per share is  calculated  each day,  Monday  through  Friday,
except days on which the New York Stock Exchange (NYSE) is closed.  The NYSE is
currently scheduled to be closed on New Year's Day, Martin Luther King Jr. Day,
Presidents'  Day,  Good Friday,  Memorial  Day,  Independence  Day,  Labor Day,
Thanksgiving,  and Christmas,  and on the preceding Friday or subsequent Monday
when one of these holidays falls on a Saturday or Sunday, respectively.

     The value of the securities of the  Aggressive  Growth,  Growth,  Growth &
Income, Income Stock, Income, and Short-Term Bond Funds is determined by one or
more of the following methods:

(1)  Portfolio  securities,  except as otherwise  noted,  traded primarily on a
     domestic  securities  exchange  are valued at the last sales price on that
     exchange.  Portfolio  securities  traded  primarily on foreign  securities
     exchanges are generally valued at the closing values of such securities on
     the exchange where primarily traded.  If no sale is reported,  the average
     of the bid and asked prices is generally  used depending upon local custom
     or regulation.

(2)  Over-the-counter  securities are priced at the last sales price or, if not
     available,  at the average of the bid and asked prices at the time trading
     closes on the NYSE.

(3)  Debt securities purchased with maturities of 60 days or less are stated at
     amortized cost which approximates market value.  Repurchase agreements are
     valued at cost.

(4)  Other debt securities may be valued each business day by a pricing service
     (the  Service)  approved by the Board of  Directors.  The Service uses the
     mean between  quoted bid and asked prices or the last sales price to price
     securities  when,  in the  Service's  judgment,  these  prices are readily
     available and are  representative  of the securities'  market values.  For
     many  securities,  such  prices are not  readily  available.  The  Service
     generally   prices  those   securities  based  on  methods  which  include
     consideration  of yields or prices of securities  of  comparable  quality,
     coupon,  maturity  and type,  indications  as to values  from  dealers  in
     securities, and general market conditions.

(5)  Securities  which cannot be valued by the methods set forth above, and all
     other  assets,  are  valued  in good  faith at fair  value  using  methods
     determined  by the Manager under the general  supervision  of the Board of
     Directors.

Securities  trading in foreign  markets may not take place on all days on which
the NYSE is open.  Further,  trading takes place in various  foreign markets on
days on which the NYSE is not open.  The  calculation of a Fund's NAV therefore
may not take place  contemporaneously  with the  determination of the prices of
securities held by a Fund. Events affecting the values of portfolio  securities
that occur between the time their prices are determined and the close of normal
trading on the NYSE on a day a Fund's NAV is  calculated  will not be reflected
in a Fund's NAV, unless the Manager  determines that the particular event would
materially  affect  NAV.  In  such  a  case,  the  Fund's  Manager,  under  the
supervision  of the  Board  of  Directors,  will  use  all  relevant  available
information to determine a fair value for the affected portfolio securities.

     The value of the Money  Market  Fund's  securities  is stated at amortized
cost which  approximates  market value. This involves valuing a security at its
cost and  thereafter  assuming  a  constant  amortization  to  maturity  of any
discount or premium,  regardless of the impact of fluctuating  interest  rates.
While this method  provides  certainty in  valuation,  it may result in periods
during which the value of an  instrument,  as determined by amortized  cost, is
higher  or lower  than the price the Fund  would  receive  upon the sale of the
instrument.

     The valuation of the Money Market Fund's portfolio  instruments based upon
their amortized cost is subject to the Fund's  adherence to certain  procedures
and conditions.  Consistent with regulatory requirements, the Manager will only
purchase  securities  with  remaining  maturities  of 397 days or less and will
maintain a dollar-weighted  average portfolio maturity of no more than 90 days.
The Manager will invest only in securities that have been determined to present
minimal   credit  risk  and  that  satisfy  the  quality  and   diversification
requirements of applicable rules and regulations of the Securities and Exchange
Commission (SEC).

     The Board of Directors has  established  procedures  designed to stabilize
the Money Market  Fund's price per share,  as computed for the purpose of sales
and redemptions,  at $1.00. There can be no assurance,  however,  that the Fund
will at all times be able to  maintain  a constant  $1.00 NAV per  share.  Such
procedures include review of the Fund's holdings at such intervals as is deemed
appropriate to determine  whether the Fund's NAV calculated by using  available
market quotations deviates from $1.00 per share

                                       2
<PAGE>

and,  if so,  whether  such  deviation  may result in  material  dilution or is
otherwise unfair to existing  shareholders.  In the event that it is determined
that such a deviation exists,  the Board of Directors will take such corrective
action as it regards as  necessary  and  appropriate.  Such  action may include
selling  portfolio  instruments  prior to maturity to realize  capital gains or
losses or to shorten average  portfolio  maturity,  withholding  dividends,  or
establishing a NAV per share by using available market quotations.

                     CONDITIONS OF PURCHASE AND REDEMPTION

NONPAYMENT

If any  order to  purchase  shares is  cancelled  due to  nonpayment  or if the
Company  does not  receive  good  funds  either  by check or  electronic  funds
transfer,  the Transfer  Agent will treat the  cancellation  as a redemption of
shares  purchased,  and you will be responsible for any resulting loss incurred
by the Fund or the Manager.  If you are a  shareholder,  the Transfer Agent can
redeem shares from any of your account(s) as reimbursement  for all losses.  In
addition,  you may be prohibited or restricted from making future  purchases in
any of the USAA Family of Funds.  A $15 fee is charged for all returned  items,
including checks and electronic funds transfers.

TRANSFER OF SHARES 

You may transfer Fund shares to another person by sending written  instructions
to USAA Shareholder  Account  Services  (Transfer  Agent).  The account must be
clearly  identified,   and  you  must  include  the  number  of  shares  to  be
transferred,   the  signatures  of  all  registered   owners,   and  all  stock
certificates,  if any, which are the subject of transfer. You also need to send
written  instructions signed by all registered owners and supporting  documents
to change an account registration due to events such as divorce,  marriage,  or
death. If a new account needs to be  established,  you must complete and return
an application to the Transfer Agent.

             ADDITIONAL INFORMATION REGARDING REDEMPTION OF SHARES

The value of your investment at the time of redemption may be more or less than
the cost at  purchase,  depending on the value of the  securities  held in each
Fund's  portfolio.  Requests  for  redemption  which are subject to any special
conditions,  or which specify an effective date other than as provided  herein,
cannot be accepted. A gain or loss for tax purposes may be realized on the sale
of shares, depending upon the price when redeemed.

     The Board of  Directors  may cause the  redemption  of an  account  with a
balance  of less than 10  shares of the  Aggressive  Growth,  Growth,  Growth &
Income, Income Stock, Income, or Short-Term Bond Funds and less than 500 shares
of the  Money  Market  Fund  provided  (1) the  value of the  account  has been
reduced,  for reasons  other than  market  action,  below the  minimum  initial
investment in such Fund at the time of the  establishment  of the account,  (2)
the account has  remained  below the minimum  level for six months,  and (3) 60
days' prior  written  notice of the proposed  redemption  has been sent to you.
Shares  will be  redeemed  at the NAV on the date fixed for  redemption  by the
Board of  Directors.  Prompt  payment  will be made by mail to your last  known
address.

     The  Company  reserves  the right to suspend  the right of  redemption  or
postpone  the date of  payment  (1) for any  periods  during  which the NYSE is
closed,  (2) when  trading in the  markets  the  Company  normally  utilizes is
restricted, or an emergency exists as determined by the SEC so that disposal of
the  Company's  investments  or  determination  of its net  asset  value is not
reasonably  practicable,  or (3) for such other periods as the SEC by order may
permit for protection of the Company's shareholders.

     For the mutual  protection of the investor and the Funds,  the Company may
require a signature  guarantee.  If  required,  EACH  signature  on the account
registration must be guaranteed.  Signature guarantees are acceptable from FDIC
member  banks,  brokers,  dealers,   municipal  securities  dealers,  municipal
securities  brokers,   government  securities  dealers,  government  securities
brokers,  credit unions,  national securities exchanges,  registered securities
associations, clearing agencies and savings associations. A signature guarantee
for active  duty  military  personnel  stationed  abroad may be  provided by an
officer of the United States Embassy or Consulate, a staff officer of the Judge
Advocate General, or an individual's commanding officer.

REDEMPTION BY CHECK  

Shareholders  in the Short-Term Bond Fund or Money Market Fund may request that
checks be issued for their accounts. Checks must be written in the amount of at
least $250.

     Checks  issued to  shareholders  of  either  Fund will be sent only to the
person in whose  name the  account  is  registered  and only to the  address of
record. The checks must be manually signed by the registered

                                       3
<PAGE>

owner(s) exactly as the account is registered. For joint accounts the signature
of either or both joint owners will be required on the check,  according to the
election made on the signature  card.  Dividends  will continue to be earned by
you until the shares are redeemed by the presentation of a check.

     When a check is presented to USAA Shareholder  Account Services  (Transfer
Agent) for payment,  a sufficient  number of full and fractional  shares in the
investor's  account  will be redeemed  to cover the amount of the check.  If an
investor's  account is not  adequate to cover the amount of a check,  the check
will be returned  unpaid.  A check drawn on an account in the  Short-Term  Bond
Fund may be returned for  insufficient  funds if the NAV per share of that Fund
declines  over the time  between the date the check was written and the date it
was  presented  for  payment.  Because  the value of the  account in either the
Short-Term Bond Fund or Money Market Fund changes as dividends are accrued on a
daily basis, checks may not be used to close an account.

     The  checkwriting  privilege  will be subject to the  customary  rules and
regulations  of State Street Bank and Trust  Company  (State Street Bank or the
Custodian)  governing checking accounts.  There is no charge to you for the use
of the checks or for subsequent reorders of checks.

     The Company  reserves  the right to assess a  processing  fee against your
account for any  redemption  check not  honored by a clearing or paying  agent.
Currently,  this fee is $15 and is subject to change at any time. Some examples
of such dishonor are improper  endorsement,  checks  written for an amount less
than the minimum check amount, and insufficient or uncollectible funds.

     The Company,  the Transfer  Agent,  and State Street Bank each reserve the
right to change or suspend the  checkwriting  privilege  upon 30 days'  written
notice to participating shareholders.

     You may  request  that the  Transfer  Agent stop  payment on a check.  The
Transfer Agent will use its best efforts to execute stop payment  instructions,
but does not guarantee that such efforts will be effective.  The Transfer Agent
will charge you $10 for each stop payment you request.

                                INVESTMENT PLANS

The Company makes available the following  investment  plans to shareholders of
all the  Funds.  At the time you  sign up for any of the  following  investment
plans that utilize the electronic funds transfer  service,  you will choose the
day of the month  (the  effective  date) on which you would  like to  regularly
purchase  shares.  When this day falls on a weekend or holiday,  the electronic
transfer will take place on the last  business day before the  effective  date.
You may terminate  your  participation  in a plan at any time.  Please call the
Manager for details and necessary forms or applications.  

AUTOMATIC PURCHASE OF SHARES 

INVESTART(R)  - A no  initial  investment  purchase  plan.  With  this plan the
regular  minimum  initial  investment  amount  is  waived  if you make  monthly
additions of at least $50 through  electronic funds transfer from a checking or
savings account.

INVESTRONIC(R) - The regular purchase of additional  shares through  electronic
funds transfer from a checking or savings account.  You may invest as little as
$50 per month.

DIRECT PURCHASE  SERVICE - The periodic  purchase of shares through  electronic
funds  transfer  from  an  employer  (including  government   allotments),   an
income-producing  investment,  or an  account  with a  participating  financial
institution.

AUTOMATIC  PURCHASE  PLAN - The  periodic  transfer  of funds from a USAA money
market fund to purchase  shares in another  non-money  market USAA mutual fund.
There is a minimum investment  required for this program of $5,000 in the money
market fund, with a monthly transaction minimum of $50.

BUY/SELL  SERVICE - The  intermittent  purchase or redemption of shares through
electronic funds transfer to or from a checking or savings account.

Participation  in these  automatic  purchase plans will permit you to engage in
dollar-cost  averaging.  For additional  information concerning the benefits of
dollar-cost averaging, see APPENDIX C.

SYSTEMATIC WITHDRAWAL PLAN  
   
If a shareholder in a single  investment  account  (accounts in different Funds
cannot be  aggregated  for this  purpose) owns shares having a NAV of $5,000 or
more, the  shareholder may request that enough shares to produce a fixed amount
of money be liquidated  from the account  monthly or  quarterly.  The amount of
each  withdrawal  must be at least $50.  Using the  electronic  funds  transfer
service, you may choose to have withdrawals  electronically  deposited at their
bank or other financial  institution.  You may also elect to have checks mailed
to a designated  address.  
    
                                       4
<PAGE>

     Such a plan may be  initiated by  depositing  shares worth at least $5,000
with  the  Transfer  Agent  and by  completing  a  Systematic  Withdrawal  Plan
application,  which  may be  requested  from  the  Manager.  You may  terminate
participation  in  the  plan  at any  time.  There  is no  charge  to  you  for
withdrawals under the Systematic Withdrawal Plan. The Company will not bear any
expenses  in  administering  the plan  beyond the  regular  transfer  agent and
custodian  costs of issuing and  redeeming  shares.  The Manager  will bear any
additional expenses of administering the plan.

     Withdrawals  will be made by redeeming full and  fractional  shares on the
date you select at the time the plan is established.  Withdrawal  payments made
under this plan may exceed  dividends  and  distributions  and, to this extent,
will  involve the use of  principal  and could  reduce the dollar value of your
investment  and  eventually  exhaust the  account.  Reinvesting  dividends  and
distributions  helps  replenish  the  account.  Because  share  values  and net
investment income can fluctuate, you should not expect withdrawals to be offset
by rising income or share value gains.

     Each  redemption  of shares  may  result in a gain or loss,  which must be
reported  on your  income tax  return.  Therefore,  you should keep an accurate
record of any gain or loss on each withdrawal.

TAX-DEFERRED RETIREMENT PLANS 

Federal  taxes on current  income may be  deferred  if you  qualify for certain
types of retirement programs. For your convenience, the Manager makes available
various forms of IRA and 403(b)(7) accounts.  The minimum initial investment in
each of these  plans is $250,  or no minimum  is  required  with a minimum  $50
monthly electronic  investment.  You may make subsequent  investments of $50 or
more  per  account  at  any  time.  You  may  make  investments  in  one or any
combination of the portfolios  described in the Prospectus of each Fund of USAA
Mutual Fund,  Inc. and USAA  Investment  Trust (not available in the Growth and
Tax Strategy Fund).
   
     Retirement plan applications for the IRA and  403(b)(7)programs  should be
sent directly to USAA Shareholder Account Services,  9800 Fredericksburg  Road,
San Antonio,  TX 78288. USAA Federal Savings Bank serves as Custodian for these
tax-deferred retirement plans under the programs made available by the Manager.
Applications  for  these  retirement  plans  received  by the  Manager  will be
forwarded to the Custodian for acceptance.
    
     An administrative  fee of $20 is deducted from the money sent to you after
closing an account.  Exceptions to the fee are:  partial  distributions,  total
transfer within USAA, and distributions due to disability or death. This charge
is  subject  to change as  provided  in the  various  agreements.  There may be
additional charges, as mutually agreed upon between you and the Custodian,  for
further services requested of the Custodian.

     Each employer or individual establishing a tax-deferred retirement plan is
advised to consult with a tax adviser  before  establishing  the plan.  You may
obtain detailed information about the plans from the Manager.

                              INVESTMENT POLICIES

The section captioned FUND INVESTMENTS in each Fund's Prospectus  describes the
fundamental investment objective and the investment policies applicable to each
Fund and the following is provided as additional information.

TAX-EXEMPT SECURITIES 

These securities  include general  obligation  bonds,  which are secured by the
issuer's  pledge of its  faith,  credit  and  taxing  power for the  payment of
principal  and  interest;  revenue  bonds,  which are payable  from the revenue
derived from a particular  facility or class of  facilities  or, in some cases,
from the proceeds of a special excise tax or other specific revenue source, but
not from the general taxing power; and certain types of industrial  development
bonds  issued  by or on  behalf  of  public  authorities  to  obtain  funds for
privately-operated  facilities,   provided  that  the  interest  paid  on  such
securities qualifies as exempt from federal income taxes.

SECTION 4(2)COMMERCIAL PAPER AND RULE 144A SECURITIES  

Each Fund may invest in  commercial  paper  issued in reliance on the  "private
placement"  exemption  from  registration  afforded  by  Section  4(2)  of  the
Securities Act of 1933 (Section 4(2) Commercial Paper). Section 4(2) Commercial
Paper is  restricted  as to  disposition  under the  federal  securities  laws;
therefore,  any resale of Section 4(2)  Commercial  Paper must be effected in a
transaction  exempt from  registration  under the  Securities Act of 1933 (1933
Act).  Section  4(2)  Commercial  Paper is normally  resold to other  investors
through or with the  assistance of the issuer or investment  dealers who make a
market in Section 4(2) Commercial Paper, thus providing liquidity.

                                       5
<PAGE>

     Each Fund may also purchase  restricted  securities eligible for resale to
"qualified institutional buyers" pursuant to Rule 144A under the 1933 Act (Rule
144A  Securities).  Rule 144A  provides a  non-exclusive  safe  harbor from the
registration  requirements of the 1933 Act for resales of certain securities to
institutional investors.

MUNICIPAL LEASE OBLIGATIONS 

The  Short-Term  Bond and Money  Market  Funds may  invest in  municipal  lease
obligations   and   certificates   of   participation   in   such   obligations
(collectively,  lease  obligations).  A lease  obligation does not constitute a
general  obligation of the  municipality  for which the  municipality's  taxing
power is pledged,  although the lease  obligation is  ordinarily  backed by the
municipality's  covenant  to  budget  for the  payments  due  under  the  lease
obligation.

     Certain  lease  obligations  contain   "non-appropriation"  clauses  which
provide  that the  municipality  has no  obligation  to make  lease  obligation
payments in future  years unless  money is  appropriated  for such purpose on a
yearly basis. Although "non-appropriation" lease obligations are secured by the
leased property,  disposition of the property in the event of foreclosure might
prove  difficult.  In  evaluating  a  potential  investment  in  such  a  lease
obligation,  the Manager will consider:  (1) the credit quality of the obligor,
(2) whether the underlying  property is essential to a  governmental  function,
and (3) whether the lease obligation contains covenants prohibiting the obligor
from substituting  similar property if the obligor fails to make appropriations
for the lease obligation.

LIQUIDITY DETERMINATIONS  

The Board of Directors has established  guidelines  pursuant to which Municipal
Lease  Obligations,  Section 4(2) Commercial Paper,  Rule 144A Securities,  and
certain  restricted debt securities  that are subject to  unconditional  put or
demand  features  exercisable  within seven days  (Restricted Put Bonds) may be
determined  to be liquid for purposes of complying  with the Funds'  investment
restrictions  applicable to investments in illiquid securities.  In determining
the liquidity of Municipal Lease Obligations, Section 4(2) Commercial Paper and
Rule 144A Securities,  the Manager will consider the following  factors,  among
others,  established by the Board of Directors: (1) the frequency of trades and
quotes for the security,  (2) the number of dealers willing to purchase or sell
the  security  and  the  number  of  other  potential  purchasers,  (3)  dealer
undertakings  to make a  market  in the  security,  and (4) the  nature  of the
security and the nature of the marketplace trades, including the time needed to
dispose of the security,  the method of soliciting offers, and the mechanics of
transfer.  Additional  factors  considered  by the Manager in  determining  the
liquidity of a municipal lease obligation are: (1) whether the lease obligation
is of a size that will be attractive to  institutional  investors,  (2) whether
the lease  obligation  contains a  non-appropriation  clause and the likelihood
that the  obligor  will fail to make an  appropriation  therefor,  and (3) such
other   factors  as  the  Manager  may   determine   to  be  relevant  to  such
determination.  In  determining  the  liquidity of  Restricted  Put Bonds,  the
Manager  will  evaluate  the credit  quality  of the party  (the Put  Provider)
issuing (or unconditionally  guaranteeing performance on) the unconditional put
or demand  feature of the Restricted Put Bond. In evaluating the credit quality
of the Put  Provider,  the Manager  will  consider  all  factors  that it deems
indicative  of the capacity of the Put Provider to meet its  obligations  under
the Restricted  Put Bond based upon a review of the Put Provider's  outstanding
debt and financial statements and general economic conditions.

     Certain  foreign  securities  (including  Eurodollar  obligations)  may be
eligible  for resale  pursuant  to Rule 144A in the United  States and may also
trade without  restriction in one or more foreign markets.  Such securities may
be determined to be liquid based upon these foreign  markets  without regard to
their  eligibility  for resale  pursuant  to Rule 144A.  In such  cases,  these
securities  will not be treated as Rule 144A  securities  for  purposes  of the
liquidity guidelines established by the Board of Directors.

CALCULATION OF PORTFOLIO WEIGHTED AVERAGE MATURITY  

Weighted  average  maturity  is  derived  by  multiplying  the  value  of  each
investment  by the  number of days  remaining  to its  maturity,  adding  these
calculations, and then dividing the total by the value of the Fund's portfolio.
An  obligation's  maturity is typically  determined on a stated final  maturity
basis, although there are some exceptions to this rule.

     With respect to obligations  held by the Funds, if it is probable that the
issuer of an instrument  will take advantage of a  maturity-shortening  device,
such as a call,  refunding,  or  redemption  provision,  the date on which  the
instrument will probably be called,  refunded, or redeemed may be considered to
be its maturity date. Also, the maturities of mortgage-backed  securities, some
asset-backed  securities and securities  subject to sinking fund  arrangements,
are determined on a weighted average life basis,  which is the average time for
principal to be repaid. For mortgage-backed  and some asset-backed  securities,
this average time is  calculated by assuming a constant  prepayment  rate (CPR)
for the life of the  mortgages or assets  backing the  security.  The CPR for a
security can vary depending  upon the level and  volatility of interest  rates.
This,  in turn,  can affect the  weighted  average  life of the  security.  The
weighted average lives of these securities will

                                       6
<PAGE>

be shorter than their stated final maturities. In addition, for purposes of the
Fund's investment policies,  an instrument will be treated as having a maturity
earlier than its stated maturity date if the instrument has technical  features
such as puts or demand  features  which,  in the judgment of the Manager,  will
result  in the  instrument  being  valued  in the  market  as though it has the
earlier maturity.

     The Money Market Fund will  determine the maturity of an obligation in its
portfolio  in  accordance  with Rule 2a-7 under the  Investment  Company Act of
1940, as amended (1940 Act).

WRITING COVERED CALL OPTIONS 

The Income  Stock Fund may write  (sell)  covered  call  options  and  purchase
options to close out  options  previously  written by the Fund.  The purpose of
writing covered call options is to generate  additional  premium income for the
Fund.  This  premium  income will serve to enhance the Fund's  total return and
will  reduce the effect of any price  decline of the  security  involved in the
option.  Covered call options will generally be written on securities which, in
the  Manager's  opinion,  are not expected to make any major price moves in the
near  future  but  which,  over the long  term,  are  deemed  to be  attractive
investments for the Fund. 

     A call option gives the holder (buyer) the right to purchase a security at
a specified  price (the  exercise  price) at any time until a certain date (the
expiration  date).  So long as the  obligation  of the writer of a call  option
continues,  he may be assigned an exercise notice by the broker-dealer  through
whom such option was sold,  requiring  him to deliver the  underlying  security
against  payment of the exercise  price.  This  obligation  terminates upon the
expiration of the call option, or such earlier time at which the writer effects
a closing  purchase  transaction by repurchasing the option which he previously
sold. To secure his obligation to deliver the  underlying  security in the case
of a call  option,  a writer is  required  to deposit in escrow the  underlying
security  or  other  assets  in  accordance  with the  rules of the  particular
clearing  corporations  and of the exchanges.  The Fund will write only covered
call  options.  This  means  that the Fund will only  write a call  option on a
security  which the Fund already owns.  The Fund will not write call options on
when-issued  securities.  The Fund will write  covered call options in standard
contracts which may be quoted on NASDAQ, or on national  securities  exchanges.
To comply with the  requirements of the securities laws in several states,  the
Fund will not write a covered call option if, as a result, the aggregate market
value of all  portfolio  securities  covering  call  options  exceeds 5% of the
market value of the Fund's total assets.

     Portfolio  securities  on  which  call  options  may be  written  will  be
purchased solely on the basis of investment  considerations consistent with the
Fund's  investment  objectives.  The  writing  of  covered  call  options  is a
conservative  investment  technique  believed to involve relatively little risk
(in contrast to the writing of naked or uncovered options,  which the Fund will
not do),  but capable of  enhancing  the Fund's  total  return.  When writing a
covered  call  option,  the  Fund,  in  return  for the  premium,  gives up the
opportunity  for profit from a price increase in the underlying  security above
the exercise price, but conversely retains the risk of loss should the price of
the security decline.  Unlike one who owns securities not subject to an option,
the Fund has no control  over when it may be  required  to sell the  underlying
securities,  since it may be assigned  an exercise  notice at any time prior to
the expiration of its  obligation as a writer.  If a call option which the Fund
has written expires, the Fund will realize a gain in the amount of the premium;
however,  such  gain may be  offset by a  decline  in the  market  value of the
underlying  security during the option period. If the call option is exercised,
the Fund will realize a gain or loss from the sale of the underlying  security.
The security  covering the call will be maintained  in a segregated  account of
the Fund's  custodian.  The Fund does not consider a security covered by a call
to be  pledged  as that term is used in the  Fund's  policy  which  limits  the
pledging or mortgaging of its assets. 

     The  premium  received is the market  value of an option.  The premium the
Fund will receive from writing a call option will reflect,  among other things,
the current market price of the underlying  security,  the  relationship of the
exercise  price to such market price,  the historical  price  volatility of the
underlying  security,  and the  length of the  option  period.  In  determining
whether a particular  call option  should be written on a particular  security,
the Manager will consider the reasonableness of the anticipated premium and the
likelihood  that a liquid  secondary  market will exist for those options.  The
premium  received by the Fund for writing covered call options will be recorded
as a  liability  in the  Fund's  statement  of  assets  and  liabilities.  This
liability  will be adjusted daily to the option's  current market value,  which
will be the  latest  sale  price at the time at which  the NAV per share of the
Fund is  computed  (close of the NYSE),  or in the  absence  of such sale,  the
latest asked price.  The liability will be extinguished  upon expiration of the
option,  the  purchase  of an  identical  option in a closing  transaction,  or
delivery of the underlying security upon the exercise of the option.

     Closing transactions may be effected to realize a profit on an outstanding
call option, to prevent an underlying  security from being called, or to permit
the  sale  of  the  underlying  security.  Furthermore,   effecting  a  closing
transaction will permit the Fund to write another call option on the underlying
security with either a different exercise price or expiration date or both.

                                       7
<PAGE>
     If the Fund desires to sell a particular  security  from its  portfolio on
which  it has  written  a call  option,  it  will  seek  to  effect  a  closing
transaction prior to, or concurrently with, the sale of the security. There is,
of  course,  no  assurance  that the Fund will be able to effect  such  closing
transactions  at a  favorable  price.  If the Fund  cannot  enter  into  such a
transaction, it may be required to hold a security that it might otherwise have
sold,  in which case it would  continue to be at market  risk on the  security.
This could result in higher transaction costs, including brokerage commissions.
The Fund will pay  brokerage  commissions  in  connection  with the  writing of
options to close out previously written options. Such brokerage commissions are
normally  higher than those  applicable  to  purchases  and sales of  portfolio
securities.

     Call options  written by the Fund will normally have  expiration  dates of
less than nine months from the date written.  The exercise price of the options
may be below,  equal to, or above the current  market values of the  underlying
securities at the time the options are written. From time to time, the Fund may
purchase an  underlying  security for delivery in  accordance  with an exercise
notice of a call option  assigned to it, rather than  delivering  such security
from its portfolio.  In such cases,  additional  brokerage  commissions will be
incurred.

     The Fund will realize a profit or loss from a closing purchase transaction
if the cost of the  transaction is less or more than the premium  received from
the  writing of the option.  Because  increases  in the market  price of a call
option will generally  reflect  increases in the market price of the underlying
security,  any loss resulting from the repurchase of a call option is likely to
be offset in whole or in part by appreciation of the underlying  security owned
by the Fund.

FORWARD CURRENCY CONTRACTS 

The Aggressive  Growth Fund may enter into forward currency  contracts in order
to protect against uncertainty in the level of future foreign exchange rates. 

     A forward  contract  involves an  agreement to purchase or sell a specific
currency at a specified  future date or over a specified time period at a price
set at the time of the contract.  These  contracts are usually traded  directly
between currency traders (usually large commercial  banks) and their customers.
A forward contract  generally has no deposit  requirements,  and no commissions
are charged.

     The  Fund  may  enter   into   forward   currency   contracts   under  two
circumstances.  First, when the Fund enters into a contract for the purchase or
sale of a security  denominated in a foreign  currency,  it may desire to "lock
in" the U.S.  dollar price of the  security.  By entering into such a contract,
the Fund will be able to protect  itself against a possible loss resulting from
an adverse change in the  relationship  between the U.S. dollar and the foreign
currency  from the date the  security is purchased or sold to the date on which
payment is made or received.  Second, when management of the Fund believes that
the currency of a specific country may deteriorate relative to the U.S. dollar,
it may enter into a forward  contract to sell that  currency.  The Fund may not
hedge with  respect to a  particular  currency  for an amount  greater than the
aggregate  market value  (determined  at the time of making any sale of forward
currency) of the securities held in its portfolio  denominated or quoted in, or
bearing a substantial correlation to, such currency.

     The use of forward contracts  involves certain risks. The precise matching
of contract amounts and the value of securities  involved generally will not be
possible  since the future value of such  securities  in  currencies  more than
likely will change  between the date the  contract is entered into and the date
it matures. The projection of short-term currency market movements is extremely
difficult  and  successful  execution  of  a  short-term  hedging  strategy  is
uncertain.  Under  normal  circumstances,  consideration  of the  prospect  for
currency  parities  will  be  incorporated  into  the  longer  term  investment
strategies.  The  Manager  believes  it is  important,  however,  to  have  the
flexibility  to enter into such  contracts when it determines it is in the best
interest of the Fund to do so. It is  impossible  to  forecast  what the market
value  of  portfolio  securities  will  be at  the  expiration  of a  contract.
Accordingly,  it may be necessary for the Fund to purchase  additional currency
(and bear the expense of such  purchase) if the market value of the security is
less than the amount of currency  the Fund is  obligated  to deliver,  and if a
decision  is made to sell the  security  and  make  delivery  of the  currency.
Conversely,  it may be necessary to sell some of the foreign currency  received
on the sale of the portfolio security if its market value exceeds the amount of
currency the Fund is obligated to deliver.

     The Fund is not required to enter into such  transactions  and will not do
so unless deemed appropriate by the Manager.

     Although  the Fund  values its assets each  business  day in terms of U.S.
dollars, it does not intend to convert its foreign currencies into U.S. dollars
on a daily basis.  It will do so from time to time,  and you should be aware of
currency  conversion  costs.  Although foreign exchange dealers do not charge a
fee for conversion,  they do realize a profit based on the difference  (spread)
between  the prices at which they are buying and  selling  various  currencies.
Thus,  a dealer may offer to sell a foreign  currency  to the Fund at one rate,
while offering a lesser rate of exchange  should the Fund desire to resell that
currency to the dealer. 

                                       8

INVESTMENTS IN REAL ESTATE INVESTMENT TRUSTS (REITS)

Because the Aggressive Growth,  Growth, Growth & Income, and Income Stock Funds
may invest their assets in equity securities of REITs,  these Funds may also be
subject to certain  risks  associated  with  direct  investments  in REITs.  In
addition,  the Short-Term  Bond and Income Funds may invest their assets in the
debt securities of REITs and, therefore, may be subject to certain other risks,
such as credit risk,  associated  with  investment  in the debt  securities  of
REITs.  REITs may be  affected  by  changes  in the  value of their  underlying
properties  and by defaults by  borrowers  or tenants.  Furthermore,  REITs are
dependent  upon  specialized  management  skills of their managers and may have
limited geographic diversification,  thereby, subjecting them to risks inherent
in  financing a limited  number of projects.  REITs  depend  generally on their
ability  to  generate  cash flow to make  distributions  to  shareholders,  and
certain REITs have  self-liquidation  provisions by which mortgages held may be
paid in full and distributions of capital returns may be made at any time.

CONVERTIBLE SECURITIES 
   
Convertible  securities are bonds,  preferred stocks, and other securities that
pay  interest or  dividends  and offer the buyer the option of  converting  the
security  into  common  stock.  The  value of  convertible  securities  depends
partially  on  interest  rate  changes  and the credit  quality of the  issuer.
Because a convertible security affords an investor the opportunity, through its
conversion  feature,  to  participate  in  the  capital   appreciation  of  the
underlying  common stock,  the value of convertible  securities also depends on
the price of the underlying common stock.
    
     The  convertible  securities  in which the Funds will  invest may be rated
below  investment  grade as  determined  by  Moody's  Investors  Service,  Inc.
(Moody's) or Standard & Poor's  Ratings  Group (S&P),  or unrated but judged by
the Manager to be of comparable  quality  (commonly  called junk bonds).  For a
more complete  description of debt ratings, see APPENDIX A. Such securities are
deemed to be speculative  and involve greater risk of default due to changes in
interest rates, economic conditions,  and the issuer's  creditworthiness.  As a
result,  their  market  prices  tend  to  fluctuate  more  than  higher-quality
securities.  During periods of general  economic  downturns or rising  interest
rates, issuers of such securities may experience  financial  difficulties which
could affect their ability to make timely interest and principal payments.  The
Fund's  ability to timely and  accurately  value and  dispose of lower  quality
securities  may also be affected by the absence or periodic  discontinuance  of
liquid trading markets.

                            INVESTMENT RESTRICTIONS

The following investment  restrictions have been adopted by the Company for and
are  applicable to each Fund.  Except with respect to the Growth & Income Fund,
Income Stock Fund,  and Short-Term  Bond Fund,  these  restrictions  may not be
changed for any given Fund without approval by the lesser of (1) 67% or more of
the voting securities  present at a meeting of the Fund if more than 50% of the
outstanding  voting  securities of the Fund are present or represented by proxy
or (2) more than 50% of the Fund's outstanding voting securities.  With respect
to the Growth & Income Fund,  Income Stock Fund, and Short-Term Bond Fund, only
restrictions 3, 4, 6, 7, 10, 13, 16 and 17 may not be changed without  approval
of shareholders, as defined herein. The investment restrictions of one Fund may
be changed without affecting those of any other Fund.

A Fund:  

(1)  May not  purchase  or retain  securities  of any issuer if any  officer or
     Director of the Company or its Manager own individually more than one-half
     of one percent (1/2%) of the securities of that issuer,  and  collectively
     the  officers and  Directors of the Company and Manager  together own more
     than 5% of the securities of that issuer.

(2)  May not purchase from or sell to any officer or Director of the Company or
     its Manager any  securities  other than shares of the capital stock of the
     Funds.

(3)  May not underwrite  securities of other  issuers,  except that the Company
     may be deemed to be a statutory  underwriter  in the  distribution  of any
     restricted securities or not readily marketable securities.

(4)  May not borrow  money,  except for  temporary or emergency  purposes in an
     amount  not  exceeding  33 1/3% of its total  assets (including  the amount
     borrowed) less liabilities (other than borrowings).

(5)  May not  invest in  companies  for the  purpose of  exercising  control or
     management.

(6)  May not, with respect to 75% of its total assets,  purchase the securities
     of any issuer (except  Government  Securities,  as such term is defined in
     the 1940  Act) if, as a  result,  the Fund  would own more than 10% of the
     outstanding  voting  securities of such issuer or the Fund would have more
     than 5% of the value of its total  assets  invested in the  securities  of
     such issuer.

                                       9
<PAGE>

(7)  May not lend any securities or make any loan if, as a result, more than 33
     1/3% of its total assets would be lent to other parties,  except that this
     limitation does not apply to purchases of debt securities or to repurchase
     agreements.

(8)  May not invest in warrants more than 2% of the value of its assets,  taken
     at the lower of cost or  market  value.  Warrants  initially  attached  to
     securities and acquired by the Fund upon original  issuance  thereof shall
     be deemed to be without value.

(9)  May not mortgage, pledge, or hypothecate any of its assets, except for the
     Income Stock Fund. A security covered by a call is not considered pledged.

(10) May not concentrate  its  investments in any one industry  although it may
     invest  up to 25% of the value of its  total  assets in any one  industry.
     Banks are not  considered  a single  industry  for purposes of this policy
     (solely with respect to the Money Market Fund),  nor shall this limitation
     apply to securities  issued or  guaranteed  by the U.S.  Government or its
     corporate instrumentalities.

(11) May not acquire securities of other open-end investment companies,  except
     in  connection  with a merger,  consolidation,  or  acquisition  of assets
     approved by the shareholders.

(12) May not  invest  more  than 5% of the  value of its  total  assets  in any
     closed-end  investment  company  and  will not  hold  more  than 3% of the
     outstanding voting stock of any closed-end investment company.

(13) May not purchase or sell commodities, commodity contracts, or real estate,
     although a Fund may invest in the  securities  of real  estate  investment
     trusts.

(14) May not engage in margin  transactions  or arbitrage or short sales, or in
     put, call,  straddle,  or spread activities,  except the Income Stock Fund
     may write covered call options as described under  INVESTMENT  POLICIES in
     this Statement of Additional Information.

(15) May not  allow its  Manager  or  officers  or  Directors  of itself or its
     Manager to take long or short  positions in shares of a Fund,  except that
     such  persons may  purchase  shares for their own  account for  investment
     purposes  only at the price  available to the public at the moment of such
     purchase. 

(16) May  not  change  the  nature  of its  business  so as to  cease  to be an
     investment company.  

(17) May not issue senior securities,  as defined in the Investment Company Act
     of 1940,  as  amended  (the 1940  Act),  except as  permitted  by  Section
     18(f)(2) and rules thereunder.  

     With respect to each Fund's concentration  policies as described above and
in its  Prospectus,  the Manager uses industry  classifications  for industries
based on categories  established by Standard & Poor's  Corporation  (Standard &
Poor's)  for  the  Standard  &  Poor's  500  Composite   Index,   with  certain
modifications.  Because the  Manager has  determined  that  certain  categories
within,  or in  addition  to,  those set forth by Standard & Poor's have unique
investment  characteristics,  additional  industries  are  included as industry
classifications.  The Manager classifies municipal obligations by projects with
similar characteristics, such as toll road revenue bonds, housing revenue bonds
or higher education revenue bonds.

     In  addition,  with  respect  to the  Money  Market  Fund's  exclusion  of
investment in banks for purposes of industry  concentration limits contained in
investment  restriction  10,  certificates of deposit,  time deposits,  bankers
acceptances,  and other  similar  money market  instruments  issued by domestic
banks may be excluded from the industry  concentration limits set forth in that
restriction.

ADDITIONAL RESTRICTIONS  

The following  restriction is not  considered to be  fundamental  policy of the
Funds.  The Board of Directors may change this additional  restriction  without
notice to or approval by the shareholders.

A Fund:

(1)  May not purchase any security while borrowings  representing  more than 5%
     of the Fund's total assets are outstanding.
                     
                            PORTFOLIO TRANSACTIONS

The Manager,  pursuant to the Advisory  Agreement dated September 21, 1990, and
subject to the general control of the Company's Board of Directors,  places all
orders for the purchase  and sale of Fund  securities.  In executing  portfolio
transactions and selecting  brokers and dealers,  it is the Company's policy to
seek the best overall terms available.  The Manager shall consider such factors
as it deems relevant,  including the breadth of the market in the security, the
financial  condition and execution  capability of the broker or dealer, and the
reasonableness of the commission,  if any, for the specific transaction or on a
continuing basis.  Securities purchased or sold in the over-the-counter  market
will be executed through  principal market makers,  except when, in the opinion
of the Manager, better prices and execution are available elsewhere.

                                      10
<PAGE>
   
The Funds will have no obligation to deal with any  particular  broker or group
of brokers in the execution of portfolio  transactions.  The Funds  contemplate
that,  consistent  with obtaining the best overall terms  available,  brokerage
transactions  may be  effected  through  USAA  Brokerage  Services,  a discount
brokerage service of the Manager.  The Company's Board of Directors has adopted
procedures in conformity  with Rule 17e-1 under the 1940 Act designed to ensure
that all brokerage  commisions  paid to USAA Brokerage  Services are reasonable
and fair.  The Company's Board of Directors  has authorized  the Manager,  as a
member of the Chicago Stock Exchange, to effect portfolio  transactions for the
Funds on such  exchange  and to retain  compensation  in  connection  with such
transactions.  Any such transactions will be effected and related  compensation
paid only in accordance with applicable SEC regulations.
    
     In the allocation of brokerage business,  preference may be given to those
broker-dealers who provide research or other services to the Manager as long as
there is no sacrifice  in obtaining  the best  overall  terms  available.  Such
research and other  services may include,  for example:  advice  concerning the
value of securities,  the advisability of investing in, purchasing,  or selling
securities,  and the availability of securities or the purchasers or sellers of
securities;  analyses and reports concerning issuers,  industries,  securities,
economic factors and trends,  portfolio strategy,  and performance of accounts;
and various functions incidental to effecting securities transactions,  such as
clearance and settlement.  In return for such services, a Fund may pay to those
brokers a higher commission than may be charged by other brokers, provided that
the Manager  determines  in good faith that such  commission  is  reasonable in
terms of either that particular transaction or of the overall responsibility of
the Manager to the Funds and its other  clients.  The receipt of research  from
broker-dealers that execute transactions on behalf of the Company may be useful
to the Manager in rendering  investment  management  services to other  clients
(including affiliates of the Manager),  and conversely,  such research provided
by  broker-dealers  who have  executed  transaction  orders  on behalf of other
clients  may be useful to the Manager in carrying  out its  obligations  to the
Company.  While such research is available to and may be used by the Manager in
providing  investment  advice to all its clients  (including  affiliates of the
Manager),  not all of such  research may be used by the Manager for the benefit
of the Company.  Such  research and services  will be in addition to and not in
lieu of research and services provided by the Manager,  and the expenses of the
Manager  will not  necessarily  be reduced by the receipt of such  supplemental
research. See THE COMPANY'S MANAGER.

     Securities of the same issuer may be purchased,  held, or sold at the same
time by the Company for any or all of its Funds, or other accounts or companies
for which the Manager acts as the investment adviser  (including  affiliates of
the  Manager).  On occasions  when the Manager  deems the purchase or sale of a
security to be in the best  interest of the Company,  as well as the  Manager's
other  clients,  the Manager,  to the extent  permitted by applicable  laws and
regulations,  may  aggregate  such  securities  to be sold or purchased for the
Company  with those to be sold or  purchased  for other  customers  in order to
obtain best execution and lower brokerage  commissions,  if any. In such event,
allocation  of the  securities  so purchased  or sold,  as well as the expenses
incurred  in the  transaction,  will be made by the  Manager  in the  manner it
considers to be most equitable and consistent with its fiduciary obligations to
all such customers,  including the Company.  In some instances,  this procedure
may impact the price and size of the position obtainable for the Company.

*  These amounts are .7%, 3.7%, 3.8%, and 1.3%, respectively, of brokerage fees
   paid by each Fund.

For the year ended July 31, 1997,  .2%,  3.9%,  3.9%, and 1.8% of the aggregate
dollar  amounts of  transactions  involving the payment of  commissions  by the
Aggressive   Growth,   Growth,   Growth  &  Income,  and  Income  Stock  Funds,
respectively,  were  effected  through  USAA  Brokerage  Services.  

                                      11
<PAGE>

     The Manager  directed a portion of the Fund's  brokerage  transactions  to
certain  broker-dealers  that  provided  the Manager with  research,  analysis,
advice  and  similar  services.   Such  transactions  amounted  to  $4,039,131,
$427,797,187,  $140,721,671,  $359,282,741,  $33,941,261, and $502,578, and the
related  brokerage   commissions  or  underwriting   commissions  were  $7,285,
$718,403,  $181,191,  $421,150, $163,280, and $2,500 for the Aggressive Growth,
Growth,  Growth & Income,  Income Stock,  Income,  and  Short-Term  Bond Funds,
respectively for the year ended July 31, 1997.

PORTFOLIO TURNOVER RATES  

The rate of portfolio  turnover will not be a limiting  factor when the Manager
deems changes in the Aggressive Growth,  Growth, Growth & Income, Income Stock,
Income,  and  Short-Term  Bond Funds'  portfolios  appropriate  in view of each
Fund's investment objectives. Although no Fund will purchase or sell securities
solely  to  achieve  short-term  trading  profits,  a Fund may  sell  portfolio
securities  without  regard to the length of time held if  consistent  with the
Fund's  investment  objectives.  A higher  degree of  portfolio  activity  will
increase brokerage costs to a Fund.

     The  portfolio  turnover rate is computed by dividing the dollar amount of
securities  purchased or sold  (whichever  is smaller) by the average  value of
securities  owned during the year.  Short-term  investments  such as commercial
paper,  short-term  U.S.  Government  securities,  and variable rate securities
(those  securities  with put date  intervals  of less  than one  year)  are not
considered when computing the turnover rate.

For the last two fiscal  years,  the Funds'  portfolio  turnover  rates were as
follows:
        FUND                       1996               1997
- ------------------                ------             ------
Aggressive Growth                 43.75%             57.15%
Growth                            62.30%             75.41%
Growth & Income                   16.13%             14.67%
Income Stock                      32.38%             34.95%
Income*                           81.26%             57.50%
Short-Term Bond                   66.81%             27.85%

_______________                

* The Fund has  simultaneously  purchased and sold the same  securities.  These
  transactions  have at times been high in volume and dissimilar to other trade
  activity  within  the Fund.  If these  transactions  were  excluded  from the
  calculation, the portfolio turnover rate would have been as follows:

                                                       YEAR ENDED JULY 31

                                                       ----          ----
Portfolio turnover                                    44.69%        22.07%
Purchases and sales of this type are as follows:
    Purchases (000)                                 $648,396       $593,587
    Sales (000)                                     $649,193       $594,283

                         FURTHER DESCRIPTION OF SHARES

The Company is  authorized  to issue  shares in separate  series or Funds.  Ten
Funds have been  established,  seven of which are described in this SAI.  Under
the Articles of  Incorporation,  the Board of Directors is authorized to create
new Funds in addition to those already existing without  shareholder  approval.
The Growth, Income, and Money Market Funds were established in the Fall of 1980
and  commenced  public  offering  of their  shares on  February  2,  1981.  The
Aggressive  Growth Fund was  established  by the Board of  Directors on July 8,
1981,  and  commenced  public  offering of its shares on October 19, 1981.  The
Income  Stock Fund was  established  by the Board of  Directors  on January 23,
1987, and commenced  public offering of its shares on May 4, 1987. The Growth &
Income and Short-Term Bond Funds were  established by the Board of Directors on
March 23, 1993, and commenced public offering of their shares on June 1, 1993.

     Each  Fund's  assets  and all  income,  earnings,  profits,  and  proceeds
thereof, subject only to the rights of creditors, are specifically allocated to
such Fund. They constitute the underlying  assets of each Fund, are required to
be segregated on the books of account,  and are to be charged with the expenses
of such Fund. Any general  expenses of the Company not readily  identifiable as
belonging  to a  particular  Fund are  allocated  on the  basis  of the  Funds'
relative net assets during the fiscal year or in such other manner as the Board
determines  to be fair and  equitable.  Each share of each Fund  represents  an
equal  proportionate  interest  in that  Fund  with  every  other  share and is
entitled to such dividends and  distributions out of the net income and capital
gains belonging to that Fund when declared by the Board.

     Under the  provisions of the Bylaws of the Company,  no annual  meeting of
shareholders is required. Thus, there will ordinarily be no shareholder meeting
unless required by the 1940 Act. Under certain

                                      12
<PAGE>

circumstances,  however,  shareholders may apply for shareholder information to
obtain signatures to request a special shareholder meeting. Moreover,  pursuant
to the Bylaws of the Company,  any  Director may be removed by the  affirmative
vote of a majority of the  outstanding  Company  shares;  and holders of 10% or
more of the outstanding  shares of the Company can require  Directors to call a
meeting of shareholders for the purpose of voting on the removal of one or more
Directors. On any matter submitted to the shareholders, the holder of each Fund
share  is  entitled  to one vote  per  share  (with  proportionate  voting  for
fractional  shares)  regardless  of the relative net asset values of the Funds'
shares.  However,  on matters  affecting an individual Fund, a separate vote of
the  shareholders  of that  Fund is  required.  Shareholders  of a Fund are not
entitled  to vote on any  matter  which  does not  affect  that  Fund but which
requires a separate vote of another Fund.  Shares do not have cumulative voting
rights,  which means that holders of more than 50% of the shares voting for the
election of Directors can elect 100% of the Company's  Board of Directors,  and
the holders of less than 50% of the shares voting for the election of Directors
will not be able to elect any person as a Director.

     Shareholders of a particular Fund might have the power to elect all of the
Directors  of the  Company  because  that  Fund  has a  majority  of the  total
outstanding  shares of the Company.  When issued,  each Fund's shares are fully
paid and  nonassessable,  have no pre-emptive or subscription  rights,  and are
fully transferable. There are no conversion rights.

                               TAX CONSIDERATIONS

Each Fund intends to qualify as a regulated investment company under Subchapter
M of the  Internal  Revenue Code of 1986,  as amended (the Code).  Accordingly,
each  Fund will not be liable  for  federal  income  taxes on its  taxable  net
investment  income and net capital  gains  (capital  gains in excess of capital
losses)  that  are  distributed  to  shareholders,   provided  that  each  Fund
distributes  at  least  90% of its net  investment  income  and net  short-term
capital gain for the taxable year.

     To qualify as a regulated investment company,  each Fund must, among other
things,  (1) derive in each  taxable year at least 90% of its gross income from
dividends,  interest, payments with respect to securities loans, gains from the
sale or other disposition of stock, securities or foreign currencies,  or other
income  derived  with  respect to its  business  of  investing  in such  stock,
securities,  or currencies (the 90% test), (2) derive in each taxable year less
than 30% of its gross  income  from the sale or other  disposition  of stock or
securities held less than three months (the 30% test),  and (3) satisfy certain
diversification  requirements,  at the  close  of each  quarter  of the  Fund's
taxable year.

     The Code imposes a nondeductible  4% excise tax on a regulated  investment
company that fails to  distribute  during each calendar year an amount at least
equal  to the sum of (1)  98% of its  taxable  net  investment  income  for the
calendar  year,  (2) 98% of its  capital  gain net income for the  twelve-month
period  ending on October 31, and (3) any prior amounts not  distributed.  Each
Fund intends to make such distributions as are necessary to avoid imposition of
the excise tax.

     Taxable  distributions  are generally  included in a  shareholder's  gross
income for the taxable year in which they are received.  Dividends  declared in
October,  November,  or December and made payable to  shareholders of record in
such a month will be deemed to have been  received on December  31, if the Fund
pays the dividend  during the following  January.  If a  shareholder  of a Fund
receives a  distribution  taxable as  long-term  capital  gain with  respect to
shares of a Fund and redeems or  exchanges  the shares  before he has held them
for more than six months,  any loss on the redemption or exchanges that is less
than or equal to the amount of the  distribution  will be treated as  long-term
capital loss.

                     DIRECTORS AND OFFICERS OF THE COMPANY

The Board of Directors of the Company  consists of seven  Directors.  Set forth
below are the Directors and officers of the Company,  their respective  offices
and  principal  occupations  during  the  last  five  years.  Unless  otherwise
indicated,  the  business  address  of  each is 9800  Fredericksburg  Rd.,  San
Antonio, TX 78288.

_______________________

  *  Effective  December 31, 1996,  George E. Brown  retired as a Director from
     the Board of Directors.

(a)  Robert  G.  Davis,  Michael  J.C.  Roth,  and John W.  Saunders,  Jr.  are
     affiliated with the Company's investment adviser,  IMCO, and, accordingly,
     receive  no  remuneration  from the  Company or any other Fund of the USAA
     Family of Funds.

(b)  At July 31, 1997,  the USAA Family of Funds  consisted of four  registered
     investment companies offering 33 individual funds. Each Director presently
     serves as a Director  or Trustee  of each  investment  company in the USAA
     Family of Funds.  In addition,  Michael J.C.  Roth  presently  serves as a
     Trustee of USAA Life  Investment  Trust, a registered  investment  company
     advised by IMCO, consisting of seven funds offered to investors in a fixed
     and variable annuity contract with USAA Life Insurance  Company.  Mr. Roth
     receives no compensation as Trustee of USAA Life Investment Trust. 

     All of the above Directors are also  Directors/Trustees of the other funds
for which IMCO serves as investment  adviser.  No  compensation  is paid by any
fund to any Director/Trustee who is a director, officer, or employee of IMCO or
its affiliates.  No pension or retirement  benefits are accrued as part of fund
expenses.  The Company reimburses certain expenses of the Directors who are not
affiliated with the investment adviser. As of August 31, 1997, the officers and
Directors of the Company and their families as a group owned beneficially or of
record less than 1% of the outstanding shares of the Company.

     As of August 31, 1997, USAA and its affiliates (including related employee
benefit plans) owned  1,097,525  shares (4.8%) of the  Aggressive  Growth Fund,
1,440,033 shares (2.1%) of the Growth Fund, 8,095,684 shares (23.1%) of the S&P
500 Index Fund,  3,369,349  shares (2.9%) of the Income Stock Fund,  20,739,610
shares  (15.7%) of the Income Fund,  and  14,849,281  shares (.7%) of the Money
Market  Fund,  2,000,010  shares  (83.8%)  of the  Science &  Technology  Fund,
2,000,010  shares  (97.1%) of the First Start Growth Fund, and no shares of the
Growth & Income Fund and Short-Term Bond Fund.

     The Company knows of no other persons who, as of August 31, 1997,  held of
record or owned beneficially 5% or more of any Fund's shares.

                             THE COMPANY'S MANAGER

As described in each Fund's Prospectus,  USAA Investment  Management Company is
the Manager and  investment  adviser,  providing  services  under the  Advisory
Agreement.  The Manager was  organized in May 1970 and has served as investment
adviser and underwriter for USAA Mutual Fund, Inc. from its inception.
   
     In addition to managing  the  Company's  assets,  the Manager  advises and
manages the investments for USAA and its affiliated  companies as well as those
of USAA Tax Exempt Fund,  Inc., USAA Investment  Trust, and USAA State Tax-Free
Trust, and USAA Life Investment Trust. As of the date of this SAI, total assets
under  management  by the Manager  were  approximately  $36  billion,  of which
approximately $22 billion were in mutual fund portfolios.
    
ADVISORY  AGREEMENT

Under the  Advisory  Agreement,  the Manager  provides an  investment  program,
carries out the investment  policy,  and manages the portfolio  assets for each
Fund.  The  Manager  is  authorized,  subject  to the  control  of the Board of
Directors of the Company,  to determine the selection,  amount, and time to buy
or sell securities for each Fund. In addition to providing investment services,
the  Manager  pays  for  office  space,  facilities,  business  equipment,  and
accounting  services (in addition to those  provided by the  Custodian) for the
Company. The Manager compensates all personnel,  officers, and Directors of the
Company if such persons are also  employees  of the Manager or its  affiliates.
For these services under the Advisory Agreement,  the Company has agreed to pay
the Manager a fee computed as described  under FUND  MANAGEMENT  in each Fund's
Prospectus.  Management  fees are  computed  and accrued  daily and are payable
monthly.

                                      16
<PAGE>

     Except for the services and facilities provided by the Manager,  the Funds
pay all other  expenses  incurred in their  operations.  Expenses for which the
Funds  are  responsible  include  taxes  (if  any),  brokerage  commissions  on
portfolio transactions (if any), expenses of issuance and redemption of shares,
charges of transfer agents, custodians and dividend disbursing agents, costs of
preparing  and  distributing  proxy  material,  costs of printing and engraving
stock   certificates,   auditing  and  legal  expenses,   certain  expenses  of
registering  and  qualifying  shares for sale,  fees of  Directors  who are not
interested  persons  (not  affiliated)  of the Manager,  costs of  typesetting,
printing  and  mailing the  Prospectus,  SAI and  periodic  reports to existing
shareholders,  and any other charges or fees not specifically  enumerated.  The
Manager pays the cost of printing  and mailing  copies of the  Prospectus,  the
SAI, and reports to prospective shareholders.

     The Advisory Agreement will remain in effect until June 30, 1998, for each
Fund and will  continue  in effect from year to year  thereafter  for each such
Fund as long as it is approved at least  annually by a vote of the  outstanding
voting  securities of such Fund (as defined by the 1940 Act) or by the Board of
Directors  (on behalf of such Fund)  including a majority of the  Directors who
are not interested  persons of the Manager or (otherwise  than as Directors) of
the Company,  at a meeting  called for the purpose of voting on such  approval.
The Advisory  Agreement  may be terminated at any time by either the Company or
the Manager on 60 days' written notice. It will automatically  terminate in the
event of its assignment (as defined in the 1940 Act).

     From time to time the Manager may,  without prior notice to  shareholders,
waive all or any portion of fees or agree to reimburse  expenses  incurred by a
Fund.  The  Manager  has  voluntarily  agreed to  continue  to limit the annual
expenses of the Short-Term Bond Fund to .50% and the Money Market Fund to .45%,
of the Fund's ANA, respectively, until December 1, 1998, and will reimburse the
Funds for all expenses in excess of such  limitations.  After December 1, 1998,
any such waiver or  reimbursement  may be terminated by the Manager at any time
without prior notice to the shareholders.

For the last three fiscal years, management fees were as follows:     

        FUND                   1995          1996         1997

Money Market                3,056,189     4,027,320     4,798,276

As a result of the Short-Term Bond and Money Market Funds'  expenses  exceeding
the expense  limitations,  the  Manager did not receive  fees to which it would
have been entitled as follows:     
         
       FUND                    1995          1996         1997
       ----                    ----          ----         ----
Short-Term  Bond            $ 136,499    $  145,849    $ 127,346  
Money Market                  154,109     1,002,670      815,135 

UNDERWRITER 

The Company has an agreement  with the Manager for exclusive  underwriting  and
distribution  of the Funds'  shares on a continuing  best efforts  basis.  This
agreement  provides that the Manager will receive no fee or other  compensation
for such distribution services.

TRANSFER AGENT 

The Transfer  Agent  performs  transfer  agent services for the Company under a
Transfer Agency Agreement.  Services include maintenance of shareholder account
records,  handling of communications  with  shareholders,  distribution of Fund
dividends,  and  production  of reports  with  respect to account  activity for
shareholders  and the  Company.  For its  services  under the  Transfer  Agency
Agreement,  USAA  Shareholder  Account Services is paid an annual fixed fee per
account  ranging  from  $23.50 to $26.00 by each  Fund.  This fee is subject to
change at any time. 

     The fee to the Transfer Agent includes  processing of all transactions and
correspondence.  Fees are billed on a monthly basis at the rate of  one-twelfth
of the annual fee. In addition, the Funds pay all out-of-pocket expenses of the
Transfer Agent and other expenses which are incurred at the specific  direction
of the Company.

                        CALCULATION OF PERFORMANCE DATA

Information regarding the total return and yield of each Fund is provided under
PERFORMANCE  INFORMATION in its Prospectus.  See VALUATION OF SECURITIES herein
for a  discussion  of the  manner  in which  each  Fund's  price  per  share is
calculated.  

YIELD - MONEY MARKET FUND 

When the Money Market Fund quotes a current  annualized yield, it is based on a
specified recent  seven-calendar-day  period. It is computed by (1) determining
the net change,  exclusive of capital  changes,  in the value of a hypothetical
preexisting  account  having a  balance  of one share at the  beginning  of the
period,  (2)  dividing  the net  change  in  account  value by the value of the
account at the beginning of the base period to obtain the base return, then (3)
multiplying the base period return by 52.14 (365/7). The resulting yield figure
is carried to the nearest hundredth of one percent.  

     The calculation includes (1) the value of additional shares purchased with
dividends on the original  share,  and dividends  declared on both the original
share  and  any  such  additional  shares,  and  (2) any  fees  charged  to all
shareholder accounts, in proportion to the length of the base period and Fund's
average  account size. 

     The capital changes  excluded from the  calculation  are realized  capital
gains and losses from the sale of securities  and unrealized  appreciation  and
depreciation.  The Fund's  effective  (compounded)  yield will be  computed  by
dividing the seven-day  annualized  yield as defined above by 365,  adding 1 to
the quotient,  raising the sum to the 365th power,  and  subtracting 1 from the
result.

     Current and effective  yields  fluctuate  daily and will vary with factors
such as  interest  rates and the  quality,  length of  maturities,  and type of
investments in the portfolio.  

          Yield For 7-day Period Ended 7/31/97 . . . 5.31%
     Effective Yield For 7-day Period Ended 7/31/97 . . . 5.45%

YIELD - INCOME FUND AND SHORT-TERM BOND FUND 

The Funds may advertise  performance in terms of a 30-day yield quotation.  The
30-day yield  quotation is computed by dividing the net  investment  income per
share earned during the period by the maximum  offering  price per share on the
last day of the period, according to the following formula:

         YIELD = 2 left [ left ({a-b}) over cd + 1 right)^6 - 1 right]

Where:   a =   dividends and interest earned during the period
         b =   expenses accrued for the period (net of reimbursement)
         c =   the average daily number of shares outstanding during the period 
               that were entitled to receive dividends
         d =   the maximum offering price per share on the last day of the
               period  

The yields for the 30-day  period ended July 31, 1997,  for the Income Fund and
Short-Term Bond Fund were 6.48% and 6.03%, respectively. 

                                      18
<PAGE>
TOTAL RETURN 

The Funds may advertise performance in terms of average annual total return for
1-, 5-, and 10-year  periods,  or for such lesser  periods as any of such Funds
have been in existence.  Average annual total return is computed by finding the
average  annual  compounded  rates of return over the periods that would equate
the initial amount invested to the ending  redeemable  value,  according to the
following formula: 
                              P(1 + T)N = ERV 

Where:   P =   a hypothetical initial payment of $1,000  
         T =   average annual total return 
         n =   number of years  
       ERV =   ending redeemable value of a hypothetical $1,000 payment made at 
               the beginning of the 1-, 5-,or 10-year periods at the end of the 
               year or period  

     The  calculation  assumes any charges are deducted from the initial $1,000
payment and assumes all dividends and distributions by such Fund are reinvested
at the price  stated in the  Prospectus  on the  reinvestment  dates during the
period,  and includes all  recurring  fees that are charged to all  shareholder
accounts.

                         AVERAGE ANNUAL TOTAL RETURNS 
                            FOR PERIODS ENDED 7/31/97

               APPENDIX A - LONG-TERM AND SHORT-TERM DEBT RATINGS

1.   LONG-TERM DEBT RATINGS:

MOODY'S INVESTORS SERVICE, INC.(MOODY'S)

Aaa      Bonds which are rated Aaa are judged to be of the best  quality.  They
         carry  the  smallest  degree  of  investment  risk  and are  generally
         referred to as "gilt  edged."  Interest  payments  are  protected by a
         large or by an  exceptionally  stable  margin and principal is secure.
         While the  various  protective  elements  are likely to  change,  such
         changes  as  can  be  visualized  are  most  unlikely  to  impair  the
         fundamentally strong position of such issues.

Aa       Bonds  which are  rated Aa are  judged  to be of high  quality  by all
         standards.  Together  with  the  Aaa  group  they  comprise  what  are
         generally  known as  high-grade  bonds.  They are rated lower than the
         best bonds because margins of protection may not be as large as in Aaa
         securities or  fluctuation  of  protective  elements may be of greater
         amplitude  or  there  may be other  elements  present  which  make the
         long-term risks appear somewhat larger than in Aaa securities.

A        Bonds which are rated A possess many favorable  investment  attributes
         and are to be considered as  upper-medium-grade  obligations.  Factors
         giving security to principal and interest are considered adequate, but
         elements may be present which suggest a  susceptibility  to impairment
         sometime in the future.

Baa      Bonds which are rated Baa are considered as  medium-grade  obligations
         (i.e., they are neither highly protected nor poorly secured). Interest
         payments and principal  security  appear  adequate for the present but
         certain    protective    elements   may   be   lacking   or   may   be
         characteristically  unreliable  over any great  length  of time.  Such
         bonds lack  outstanding  investment  characteristics  and in fact have
         speculative characteristics as well.

Ba       Bonds  which are rated Ba are  judged  to have  speculative  elements;
         their  future  cannot  be  considered  as  well  assured.   Often  the
         protection  of interest and principal  payments may be very  moderate,
         and thereby not well safeguarded  during other good and bad times over
         the future. Uncertainty of position characterizes bonds in this class.

                                       19
<PAGE>

B        Bonds  which  are  rated  B  generally  lack  characteristics  of  the
         desirable investment.  Assurance of interest and principal payments or
         of  maintenance of other terms of the contract over any long period of
         time may be small.

Caa      Bonds which are rated Caa are of poor standing.  Such issues may be in
         default or there may be present  elements  of danger  with  respect to
         principal or interest.

Ca       Bonds which are rated Ca represent  obligations  which are speculative
         in a high  degree.  Such  issues  are often in  default  or have other
         marked shortcomings.

C        Bonds  which  are rated C are the  lowest  rated  class of bonds,  and
         issues so rated can be regarded as having  extremely poor prospects of
         ever attaining any real investment standing.

STANDARD & POOR'S RATINGS GROUP (S&P)

AAA      Debt rated AAA has the highest rating assigned by S&P. Capacity to pay
         interest and repay principal is extremely strong.

AA       Debt rated AA has a very  strong  capacity to pay  interest  and repay
         principal  and  differs  from the highest  rated  issues only in small
         degree.

A        Debt rated A has a strong capacity to pay interest and repay principal
         although it is somewhat  more  susceptible  to the adverse  effects of
         changes in circumstances  and economic  conditions than debt in higher
         rated categories.

BBB      Debt  rated BBB is  regarded  as having an  adequate  capacity  to pay
         interest and repay principal.  Whereas it normally  exhibits  adequate
         protection   parameters,   adverse  economic  conditions  or  changing
         circumstances  are more  likely to lead to a weakened  capacity to pay
         interest and repay  principal for debt in this category than in higher
         rated categories.

BB       Debt rated BB has less near-term  vulnerability  to default than other
         speculative issues.  However, it faces major ongoing  uncertainties or
         exposure to adverse business,  financial, or economic conditions which
         could  lead  to  inadequate  capacity  to  meet  timely  interest  and
         principal  payments.  The BB  rating  category  is also  used for debt
         subordinated to senior debt that is assigned an actual or implied BBB-
         rating.

B        Debt rated B has a greater  vulnerability to default but currently has
         the  capacity to meet  interest  payments  and  principal  repayments.
         Adverse business, financial, or economic conditions will likely impair
         capacity or  willingness  to pay interest and repay  principal.  The B
         rating category is also used for debt subordinated to senior debt that
         is assigned an actual or implied BB or BB- rating.

CCC      Debt rated CCC has a currently identifiable  vulnerability to default,
         and is dependent  upon  favorable  business,  financial,  and economic
         conditions  to meet  timely  payment  of  interest  and  repayment  of
         principal.  In the event of adverse business,  financial,  or economic
         conditions,  it is not likely to have the capacity to pay interest and
         repay  principal.  The CCC  rating  category  is also  used  for  debt
         subordinated to senior debt that is assigned an actual or implied B or
         B- rating.

CC       The rating CC typically is applied to debt subordinated to senior debt
         that is assigned an actual or implied CCC rating.

C        The rating C typically is applied to debt  subordinated to senior debt
         which is assigned an actual or implied CCC- debt rating.  The C rating
         may be used to cover a situation where a bankruptcy  petition has been
         filed, but debt service payments are continued.

CI       The rating CI is  reserved  for income  bonds on which no  interest is
         being paid.  

D        Debt rated D is in payment default. The D rating category is used when
         interest  payments or principal  payments are not made on the date due
         even if the  applicable  grace  period  has not  expired,  unless  S&P
         believes that such payments will be made during such grace period. The
         D rating also will be used upon the filing of a bankruptcy petition if
         debt service payments are jeopardized.  

PLUS  (+) OR MINUS  (-):  THE  RATINGS  FROM AA TO CCC MAY BE  MODIFIED  BY THE
ADDITION  OF A PLUS OR MINUS SIGN TO SHOW  RELATIVE  STANDING  WITHIN THE MAJOR
RATING CATEGORIES. 

FITCH INVESTORS SERVICE, INC. (FITCH)

AAA      Bonds  considered  to be  investment  grade and of the highest  credit
         quality.  The  obligor  has an  exceptionally  strong  ability  to pay
         interest  and repay  principal,  which is  unlikely  to be affected by
         reasonably foreseeable events.  

AA       Bonds  considered  to be  investment  grade  and of very  high  credit
         quality.  The obligor's ability to pay interest and repay principal is
         very strong,  although not quite as strong as bonds rated AAA. Because
         bonds  rated  in the  AAA  and AA  categories  are  not  significantly
         vulnerable to  foreseeable  future  developments,  short-term  debt of
         these issuers is generally rated F-1+. 

                                      20
<PAGE>
A        Bonds  considered to be investment  grade and of high credit  quality.
         The  obligor's   ability  to  pay  interest  and  repay  principal  is
         considered to be strong, but may be more vulnerable to adverse changes
         in  economic  conditions  and  circumstances  than bonds  with  higher
         ratings.   

BBB      Bonds  considered to be investment  grade and of  satisfactory  credit
         quality.  The obligor's ability to pay interest and repay principal is
         considered to be adequate.  Adverse changes in economic conditions and
         circumstances,  however,  are more  likely to have  adverse  impact on
         these bonds, and therefore, impair timely payment. The likelihood that
         the ratings of these bonds will fall below  investment grade is higher
         than for bonds with higher ratings.  

DUFF & PHELPS  (D&P) 

AAA      Highest credit quality.  The risk factors are  negligible,  being only
         slightly more than for risk-free U.S. Treasury debt. 

AA       High credit quality. Protection factors are strong. Risk is modest but
         may vary slightly from time to time because of economic conditions.  

A        Protection factors are average but adequate. However, risk factors are
         more variable and greater in periods of economic stress.  

BBB      Below average protection  factors but still considered  sufficient for
         prudent investment.  Considerable  variability in risk during economic
         cycles.  

2. SHORT-TERM DEBT RATINGS:  

MOODY'S CORPORATE AND GOVERNMENT
         
Prime-1  Issuers rated  Prime-1 (or  supporting  institutions)  have a
         superior ability for repayment of senior  short-term debt obligations.
         Prime-1  repayment  ability  will  often be  evidenced  by many of the
         following characteristics:   

         o    Leading market positions in well-established  industries. 
         o    High rates of return on funds employed. 
         o    Conservative  capitalization  structure with moderate reliance on 
              debt and ample asset protection.  
         o    Broad margins in earnings coverage of fixed financial charges and
              high internal cash generation.  
         o    Well-established  access  to  a  range of  financial  markets and
              assured sources of alternate liquidity.  

Prime-2  Issuers  rated  Prime-2  (or  supporting  institutions)  have a strong
         ability for repayment of senior short-term debt obligations. This will
         normally be evidenced by many of the  characteristics  cited above but
         to a lesser degree.  Earnings trends and coverage ratios, while sound,
         may be more  subject  to  variation.  Capitalization  characteristics,
         while still appropriate,  may be more affected by external conditions.
         Ample alternate liquidity is maintained. 

Prime-3  Issuers rated Prime-3 (or supporting  institutions) have an acceptable
         ability for repayment of short-term senior obligations.  The effect of
         industry   characteristics   and  market   composition   may  be  more
         pronounced.  Variability in earnings and  profitability  may result in
         changes in the level of debt protection  measurements  and may require
         relatively high financial  leverage.  Adequate alternate  liquidity is
         maintained.  

MOODY'S  MUNICIPAL 

MIG 1/VMIG 1   This designation  denotes best quality.  There is present strong
               protection by established cash flows, superior liquidity support
               or demonstrated broadbased access to the market for refinancing.
               
MIG 2/VMIG 2   This  designation  denotes high quality.  Margins of protection 
               are ample although not so large as in the preceding group.
               
MIG 3/VMIG 3   This designation denotes favorable quality. All securityelements
               are accounted for but there is lacking the undeniable  strength 
               of the preceding grades.  Liquidity and cash flow protection may
               be narrow and market access for refinancing is likely to be less
               well established.  

MIG 4/VMIG 4   This designation  denotes adequate quality.  Protection commonly
               regarded  as required  of an  investment security is present and
               although not distinctly or predominantly speculative, there is 
               specific risk.   

S&P CORPORATE AND GOVERNMENT 

A-1      This highest  category  indicates that the degree of safety  regarding
         timely payment is strong. Those issues determined to possess extremely
         strong  safety  characteristics  are  denoted  with  a plus  (+)  sign
         designation.  

A-2      Capacity  for  timely  payment  on  issues  with this  designation  is
         satisfactory. However, the relative degree of safety is not as high as
         for issues designated A-1. 

                                       21
<PAGE>

A-3      Designation  indicates a  satisfactory  capacity  for timely  payment.
         Issues with this designation, however, are somewhat more vulnerable to
         the  adverse  effects  of changes in  circumstances  than  obligations
         carrying the higher designations.  

S&P MUNICIPAL 

SP-1     Strong  capacity to pay principal and interest.  Issues  determined to
         possess very strong characteristics are given a plus (+) designation.

SP-2     Satisfactory  capacity  to  pay  principal  and  interest,  with  some
         vulnerability to adverse  financial and economic changes over the term
         of the notes. 

FITCH 

F-1+     Exceptionally  strong credit quality.  Issues assigned this rating are
         regarded  as having  the  strongest  degree of  assurance  for  timely
         payment.  

F-1      Very strong credit  quality.  Issues  assigned this rating  reflect an
         assurance for timely  payment only slightly less in degree than issues
         rated F-1+. 

F-2      Good credit  quality.  Issues assigned this rating have a satisfactory
         degree of assurance for timely  payments,  but the margin of safety is
         not as great as for issuers assigned F-1+ and F-1 ratings.  

F-3      Fair credit quality.  Issues assigned this rating have characteristics
         suggesting  that  the  degree  of  assurance  for  timely  payment  is
         adequate;   however,  near-term  adverse  changes  could  cause  these
         securities to be rated below investment grade. 

DUFF & PHELPS INC. 

D-1+     Highest certainty of timely payment.  Short-term liquidity,  including
         internal  operating  factors and/or access to  alternative  sources of
         funds,  is  outstanding,  and  safety  is just  below  risk-free  U.S.
         Treasury short-term obligations.  

D-1      Very high certainty of timely payment. Liquidity factors are excellent
         and supported by good fundamental protection factors. Risk factors are
         minor.  

D-1-     High  certainty of timely  payment.  Liquidity  factors are strong and
         supported by good  fundamental  protection  factors.  Risk factors are
         very small.  

D-2      Good  certainty  of timely  payment.  Liquidity  factors  and  company
         fundamentals  are sound.  Although  ongoing  funding needs may enlarge
         total financing requirements,  access to capital markets is good. Risk
         factors are small.  

D-3      Satisfactory  liquidity and other protection factors qualify issues as
         to  investment  grade.  Risk  factors  are larger and  subject to more
         variation. Nevertheless, timely payment is expected.   

THOMPSON BANKWATCH, INC.  

TBW-1    The highest category;  indicates a very high likelihood that principal
         and interest will be paid on a timely basis.  

TBW-2    The second  highest  category;  while the  degree of safety  regarding
         timely  repayment  of principal  and interest is strong,  the relative
         degree of safety is not as high as for issues rated  TBW-1.  

TBW-3    The  lowest  investment  grade  category;  indicates  that  while  the
         obligation is more susceptible to adverse  developments (both internal
         and external) than those with higher ratings,  the capacity to service
         principal and interest in a timely fashion is considered adequate.
         
TBW-4    The lowest rating category;  this rating is regarded as non-investment
         grade and therefore speculative. 

IBCA INC.  

A1       Obligations  supported by the highest  capacity for timely  repayment.
         Where issues possess a particularly strong credit feature, a rating of
         A1+ is assigned.  

A2       Obligations  supported by a satisfactory capacity for timely repayment
         although  such  capacity  may be  susceptible  to  adverse  changes in
         business, economic or financial conditions.  

A3       Obligations  supported by an adequate  capacity for timely  repayment.
         Such  capacity is more  susceptible  to adverse  changes in  business,
         economic  or  financial  conditions  than for  obligations  in  higher
         categories.  

B        Obligations for which the capacity for timely repayment is susceptible
         to adverse changes in business, economic, or financial conditions.  

C        Obligations  for which  there is a high risk of  default  or which are
         currently in default.

                       APPENDIX C - DOLLAR-COST AVERAGING

Dollar-cost  averaging  is a systematic  investing  method which can be used by
investors as a disciplined technique for investing.  A fixed amount of money is
invested in a security (such as a stock or mutual fund) on a regular basis over
a period of time,  regardless  of whether  securities  markets are moving up or
down.

     This  practice  reduces  average  share costs to the investor who acquires
more shares in periods of lower  securities  prices and fewer shares in periods
of higher prices.

     While  dollar-cost  averaging does not assure a profit or protect  against
loss in declining markets, this investment strategy is an effective way to help
calm the effect of fluctuations in the financial markets.  Systematic investing
involves  continuous  investment in securities  regardless of fluctuating price
levels of such securities. Investors should consider their financial ability to
continue purchases through periods of low and high price levels.

     As the following chart  illustrates,  dollar-cost  averaging tends to keep
the overall cost of shares lower.  This example is for  illustration  only, and
different trends would result in different average costs.
