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

WHAT IS THE FUND'S INVESTMENT
OBJECTIVE AND MAIN STRATEGY?

The Fund's  investment  objective is capital  appreciation.  We will attempt to
achieve  this  objective  by investing  the Fund's  assets  primarily in equity
securities of companies with the prospect of rapidly growing earnings.

In view of the risks inherent in all  investments  in  securities,  there is no
assurance that the Fund's  objective will be achieved.  See FUND INVESTMENTS on
page 5 for more information.

MAIN RISKS OF INVESTING IN THIS FUND

The  primary  risks of  investing  in this Fund are market risk and the risk of
investing in companies with small market capitalizations.

[SIDEBAR]
     MARKET  CAPITALIZATION  IS THE  TOTAL  MARKET  VALUE  OF A  COMPANY'S
     OUTSTANDING SHARES OF COMMON STOCK.

o    MARKET  RISK  involves  the  possibility  that  the  value  of the  Fund's
     investments  in equity  securities  will  decline in a down stock  market,
     regardless of the success or failure of any one company's operations.

o    SMALL CAP COMPANY RISK  involves the greater risk of investing in smaller,
     less  well-known  companies,   as  opposed  to  investing  in  established
     companies with proven track records.

Another risk of the Fund described  later in the Prospectus  includes the risks
of foreign investing.  As with other mutual funds,  losing money is also a risk
of investing in this Fund.

As you consider an investment  in this 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 the  investment  for long periods of time
to ride out down periods.

An  investment  in this Fund is not a deposit of USAA Federal  Savings Bank, or
any other  bank,  and is not  insured  or  guaranteed  by the  Federal  Deposit
Insurance Corporation or any other government agency.

[CAUTION LIGHT]

Look for this symbol throughout the Prospectus. We use it to mark more detailed
information about the risks you will face as a Fund shareholder.

                                       2
<PAGE>
IS THIS FUND FOR YOU?

This Fund might be appropriate as part of your investment portfolio if . . .

   o You are willing to accept very high risk.
   o You are looking for a long-term investment.
   o You are willing to give up current income for long-term growth.

This Fund may not be appropriate as part of your investment portfolio if . . .

   o You are unwilling to take greater risk for long-term goals.

   o You need an investment that provides steady income.
   o You need an investment that provides tax-free income.

This  Fund by  itself  does  not  constitute  a  balanced  investment  program.
Diversifying  your investments may improve your long-run  investment return and
lower the volatility of your overall investment portfolio.

COULD THE VALUE OF YOUR INVESTMENT
IN THIS FUND FLUCTUATE?

Yes,  it  could.  In fact,  the  value of your  investment  in this  Fund  will
fluctuate with the changing market values of the investments in the Fund. While
the  portfolio  will  be  broadly  diversified,   we  expect  the  Fund  to  be
significantly  more  volatile  than the average  equity  mutual fund due to the
Fund's investments in smaller, less well-known companies.

The bar chart,  shown below,  illustrates the Fund's volatility and performance
from year to year over the past ten years.

Total Return

[SIDEBAR]
     TOTAL RETURN MEASURES THE PRICE CHANGE IN A SHARE ASSUMING THE
     REINVESTMENT OF ALL DIVIDEND INCOME AND CAPITAL GAIN DISTRIBUTIONS.

All mutual funds must use the same formula to calculate total return.

FUND INVESTMENTS

Principal Investment Strategies and Risks

 Q   What is the Fund's principal investment strategy?

 A   The Fund's principal strategy is the investment of its assets primarily in
     equity  securities  of  companies  with 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,  securities  convertible  into common stocks,  and securities that
     carry the right to buy common stocks.

     As a temporary defensive measure because of market,  economic,  political,
     or other  conditions,  we may  invest up to 100% of the  Fund's  assets in
     investment-grade, short-term debt instruments.

                                       5
<PAGE>
     This may result in the Fund not achieving its investment  objective during
     the time it is in this temporary defensive posture.

     We generally will not trade the Fund's securities for short-term  profits;
     however, if circumstances  warrant, we may need to actively and frequently
     trade Fund securities to achieve the Fund's principal investment strategy.
     The Fund's  portfolio  turnover rate will vary from year to year depending
     on market conditions. A high turnover rate increases transaction costs and
     may increase taxable capital gains; therefore, we will carefully weigh the
     anticipated benefits of trading.

[CAUTION LIGHT]
MARKET RISK. Because this Fund invests in equity  securities,  it is subject to
stock  market  risk.  Stock  prices in general may  decline  over short or even
extended  periods,  regardless  of  the  success  or  failure  of  a  company's
operations. Stock markets tend to run in cycles, with periods when stock prices
generally  go up,  known as "bull"  markets,  and  periods  when  stock  prices
generally go down, referred to as "bear" markets.  Equity securities tend to go
up and down more than bonds.

[CAUTION LIGHT]
SMALL CAP COMPANY RISKS. Small cap companies may be more vulnerable than larger
companies to adverse business or economic developments. Small cap companies may
also have limited product lines, markets, or financial resources. Securities of
such  companies may be less liquid and more volatile than  securities of larger
companies or the market averages in general and, therefore, may involve greater
risk than investing in larger companies.  In addition,  small cap companies may
not  be  well-known  to  the  investing  public,  may  not  have  institutional
ownership, and may have only cyclical, static, or moderate growth prospects.

 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  purchased in either  foreign or U.S.  markets.  These  foreign
     holdings  may include  securities  issued in  emerging  markets as well as
     securities issued in established markets.

[CAUTION LIGHT]

FOREIGN  INVESTING RISKS.  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;  difficulties in
obtaining legal judgments;  and foreign withholding taxes. Two forms of foreign
investing risk are emerging markets risk and political risk.

                                       6
<PAGE>
o    EMERGING  MARKETS  RISK.  Investments  in countries  that are in the early
     stages  of their  industrial  development  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.

o    POLITICAL  RISK.  Political  risk  includes a greater  potential for coups
     d'etat, revolts, and expropriation by governmental organizations.

 Q   How are the decisions to buy and sell securities made?

 A   We  invest  in  companies  that  have  rapid  sales  and  earnings  growth
     potential.  These companies tend to be in the small and mid capitalization
     categories,  but we will  also  invest in large  capitalization  companies
     where  appropriate.  We seek  companies  that are well  positioned to take
     advantage of emerging, long-term social and economic trends and have ample
     financial  resources to sustain  their  growth.  We may reduce or sell the
     Fund's   investments  in  companies  if  their  stock  prices   appreciate
     excessively in relation to fundamental  prospects.  Companies will also be
     sold if they fail to realize  their growth  potential or if there are more
     attractive opportunities elsewhere.

For additional  information  about other  securities in which we may invest the
Fund's assets, see APPENDIX A on page 20.

FUND MANAGEMENT

USAA  Investment  Management  Company serves as the manager and  distributor of
this  Fund.  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  $40   billion in total  assets  under
management.  Our mailing address is 9800  Fredericksburg  Road, San Antonio, TX
78288.

We provide management  services to the Fund pursuant to an Advisory  Agreement.
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 Fund's 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

                                       7
<PAGE>
million,  and  one-third of one percent  (.33%) for that portion of average net
assets in excess of $300 million. The fee we received for the fiscal year ended
July 31,  1999,  was  equal to .38% of  average  net  assets.  We also  provide
services  related to selling the Fund's shares and receive no compensation  for
those services.

Portfolio Transactions

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

Portfolio Managers

Eric M. Efron and John K. Cabell,  Jr.,  Assistant  Vice  Presidents  of Equity
Investments, have managed the Fund since March 1995.

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 to fit your own risk and reward goals.

III. USAA's Family of Funds

We offer you  another  alternative  with our  asset  strategy  funds  listed in
APPENDIX B under asset allocation on page 21. These unique mutual funds provide
a  professionally  managed,  diversified  investment  portfolio within a mutual
fund.  Designed for the individual who prefers to delegate the asset allocation
process to an investment  manager,  their  structure  achieves  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 member service
representatives  stand  ready to assist you with your  choices  and to help you
craft a  portfolio  to meet your  needs.  Refer to  APPENDIX B on page 21 for a
complete list of the USAA Family of No-Load Mutual Funds.

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),  phone,  or Internet.  A
complete, signed application is required to open your initial account. However,
after  you open your  initial  account  with us,  you will not need to fill out
another  application  to invest in  another  Fund  unless the  registration  is
different.

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.  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  and  payment  prior to that time,  your
purchase price will be the NAV per share determined for that day. If we receive
your  request or payment  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.
This will avoid a potential  four- to six-week  delay in the effective  date of
your  purchase.  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), your redemption will be effective on the next business day.

We will send you your  money  within  seven days  after the  effective  date of
redemption.  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.  For federal
income tax purposes,  a redemption  is a taxable  event;  and as such,  you may
realize a capital gain or loss.  Such capital  gains or losses are based on the
difference  between your cost basis in the shares and the price  received  upon
redemption.

<PAGE>
Account Balance

USAA Shareholder  Account Services (SAS), the Fund's transfer agent, may assess
annually a small balance account fee of $12 to each shareholder  account with a
balance  of less than  $2,000 at the time of  assessment.  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).

Fund Rights

The Fund reserves the right to:

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

o   limit or  discontinue  the offering of shares of the Fund 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 Fund's Board
    of Directors and the required notice has been given to shareholders;

o   require a  signature  guarantee  for  transactions  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 ten 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.  Exchanges  made through USAA  TouchLine(R)
and the Internet  require an ESA and EFT Buy/Sell  authorization on file. After
we receive the exchange orders,  the Fund's transfer agent will  simultaneously
process exchange redemptions

                                      14
<PAGE>
and  purchases at the share prices next  determined.  The  investment  minimums
applicable to share  purchases also apply to exchanges.  For federal income tax
purposes,  an exchange  between Funds is a taxable event;  and as such, you may
realize a capital gain or loss.  Such capital  gains or losses are based on the
difference  between your cost basis in the shares and the price  received  upon
exchange.

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

[SIDEBAR]
     NAV PER SHARE EQUALS TOTAL ASSETS MINUS LIABILITIES DIVIDED BY # OF
     SHARES OUTSTANDING

The price at which you  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.  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.

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
valued at the last quoted sales price, or the most recently  determined closing
price calculated  according to local market  convention,  available at the time
the Fund is valued.  If no sale is  reported,  the average of the bid and asked
prices is generally used.

Securities  trading in various  foreign markets may take place on days when the
NYSE is closed.  Further,  when the NYSE is open,  the  foreign  markets may be
closed.  Therefore, the calculation of the Fund's NAV may not take place at the
same time the prices of certain securities held by the Fund are determined.  In
most cases,  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 the Fund's NAV is  calculated  will not be  reflected  in the
Fund's NAV. If, however,  we determine that a particular event would materially
affect the Fund's NAV, then we, under the general

                                      15
<PAGE>
supervision of the Fund's Board of Directors, will use all relevant,  available
information to determine a fair value for the affected portfolio securities.

Over-the-counter securities are generally priced at the last sales price or, if
not available, at the average of the bid and asked prices.

Debt  securities  purchased  with  maturities  of 60 days or less are stated at
amortized  cost,  which  approximates  market value.  Other debt securities are
valued each  business  day at their  current  market value as  determined  by a
pricing  service  approved by the Fund's Board of  Directors.  Securities  that
cannot be valued by these  methods,  and all other  assets,  are valued in good
faith  at fair  value  using  methods  we have  determined  under  the  general
supervision of the Fund's Board of Directors.

For  additional  information  on how  securities  are valued,  see VALUATION OF
SECURITIES in the Fund's Statement of Additional Information.

Dividends and Distributions

The Fund pays net  investment  income  dividends  yearly.  Any net capital gain
distribution  usually  occurs  within 60 days of the July 31  fiscal  year end,
which  would be  somewhere  around  the end of  September.  The Fund  will make
additional payments to shareholders,  if necessary,  to avoid the imposition of
any federal income or excise tax.

We  will   automatically   reinvest  all  income  dividends  and  capital  gain
distributions  in the Fund unless you instruct us differently.  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.  You should  consider
carefully  the  effects of  purchasing  shares of the Fund  shortly  before any
dividend or distribution.  Some or all of 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 Taxpayer
Relief  Act  of  1997  and  the  technical   provisions   adopted  by  the  IRS
Restructuring  and Reform Act of 1998 may  affect the status and  treatment  of
certain distributions shareholders receive from the Fund.

                                      16
<PAGE>
Because each investor's tax  circumstances  are unique and because the tax laws
are subject to change,  we recommend  you consult  your tax adviser  about your
investment.

SHAREHOLDER - Dividends from taxable net investment income and distributions of
net  short-term  capital gains are taxable to you 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 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 information to you annually concerning the tax
status of dividends and distributions for federal income tax purposes.

                                      17

Year 2000

Like other organizations around the world, the Fund could be adversely affected
if the computer systems used by the Fund, its service  providers,  or companies
in which the Fund invests do not  properly  process and  calculate  information
that relates to dates beginning on January 1, 2000, and beyond.  This situation
may occur because for many years computer  programmers  used only two digits to
describe  years,  such as 98 for 1998. A program written in this manner may not
work when it encounters the year 00. To confront this situation, USAA companies
have  spent  much  effort and money;  and we are  confident  that our  critical
systems  are  essentially  prepared  for the Year  2000.  In  addition,  we are
actively assessing the Year 2000 readiness of our service providers,  partners,
and companies in whose  securities we invest.  It is not possible for us to say
that you will experience no effect from this situation,  but we can say that we
are making a large effort to avoid ill effects upon our shareholders.

We do believe you are entitled to know with certainty that we will stand behind
your share balance as of the close of business in 1999. When the market reopens
in 2000,  should any computer problem cause a change in the number of shares in
your account, we will return your account to its proper share balance.

                                   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 the Fund's  assets in  convertible  securities,  which are bonds,
preferred stocks, and other securities that pay interest or dividends and offer
the buyer the ability to convert 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 a foreign
currency and desires to "lock in" the U.S.  dollar price of that security until
settlement.

ILLIQUID SECURITIES

We may  invest  up to 15% of the  Fund's  net  assets  in  securities  that are
illiquid.  Illiquid securities are those securities which cannot be disposed of
in the ordinary course of business,  seven days or less, at  approximately  the
same value at which the Fund has valued the securities.

MONEY MARKET INSTRUMENTS

We may hold a certain  portion of the Fund's assets in  investment-grade,  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,
banker's  acceptances,  and  other  financial  institution  obligations.  These
securities may carry fixed or variable interest rates.

AMERICAN DEPOSITARY RECEIPTS (ADRS)

We may invest the Fund's  assets in ADRs,  which are  foreign  shares held by a
U.S.  bank that issues a receipt  evidencing  ownership.  Dividends are paid in
U.S. dollars.

GLOBAL DEPOSITARY RECEIPTS (GDRS)

We may invest the Fund's  assets in GDRs,  which are  foreign  shares held by a
U.S. or foreign bank that issues a receipt evidencing ownership.  Dividends are
paid in U.S. dollars.

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

WHAT IS THE FUND'S INVESTMENT
OBJECTIVE AND MAIN STRATEGY?

The Fund's  primary  investment  objective is long-term  growth of capital with
secondary  objectives of regular income and conservation of principal.  We will
attempt to achieve  these  objectives  by investing the Fund's assets in stocks
that, at the time of purchase, are considered out of favor and undervalued.

In view of the risks inherent in all  investments  in  securities,  there is no
assurance that the Fund's objectives will be achieved.  See FUND INVESTMENTS on
page 5 for more information.

MAIN RISKS OF INVESTING IN THIS FUND

The primary risk of investing in this Fund is market risk.

o   MARKET  RISK  involves  the  possibility  that  the  value  of  the  Fund's
    investments  in equity  securities  will  decline in a down  stock  market,
    regardless of the success or failure of any one company's operations.

Another  risk of the  Fund  described  later in the  Prospectus  is the risk of
foreign investing.  As with other mutual funds,  losing money is also a risk of
investing in this Fund.

As you consider an investment  in this 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 the  investment  for long periods of time
to ride out down periods.

An  investment  in this Fund is not a deposit of USAA Federal  Savings Bank, or
any other  bank,  and is not  insured  or  guaranteed  by the  Federal  Deposit
Insurance Corporation or any other government agency.

[CAUTION LIGHT]

Look for this symbol throughout the Prospectus. We use it to mark more detailed
information about the risks you will face as a Fund shareholder.

IS THIS FUND FOR YOU?

This Fund might be appropriate as part of your investment portfolio if . . .

   o You are looking for long-term growth.
   o You are willing to accept moderate to high risk.
   o You are looking for a long-term investment.

                                       2
<PAGE>
This Fund may not be appropriate as part of your investment portfolio if . . .

   o You are unwilling to take greater risk for long-term goals.

   o You need an investment that provides regular income or
     tax-free income.

This  Fund by  itself  does  not  constitute  a  balanced  investment  program.
Diversifying  your investments may improve your long-run  investment return and
lower the volatility of your overall investment portfolio.

COULD THE VALUE OF YOUR INVESTMENT
IN THIS FUND FLUCTUATE?

Yes,  it  could.  In fact,  the  value of your  investment  in this  Fund  will
fluctuate with the changing  market values of the  investments in the Fund. The
bar chart, shown below,  illustrates the Fund's volatility and performance from
year to year over the past ten years.

Total Return

[SIDEBAR]
     TOTAL RETURN MEASURES THE PRICE CHANGE IN A SHARE ASSUMING THE
     REINVESTMENT OF ALL DIVIDEND INCOME AND CAPITAL GAIN DISTRIBUTIONS.

All mutual funds must use the same formula to calculate total return.

          THE FUND'S TOTAL RETURN FOR THE NINE-MONTH PERIOD ENDED
          SEPTEMBER 30, 1999, WAS 4.94%.

During the  periods  shown in the bar chart,  the  highest  total  return for a
quarter was 26.08%  (quarter  ending  December  31,  1998) and the lowest total
return for a quarter was -16.14% (quarter ending December 31, 1997).

The table below shows how the Fund's average annual total returns for the one-,
five-, and ten-year periods, as well as the life of the Fund, compared to those

FUND INVESTMENTS

Principal Investment Strategies and Risks

 Q   What is the Fund's principal investment strategy?

 A   The Fund's principal strategy is the investment of its assets primarily in
     common stocks.  We may also invest the Fund's assets in warrants,  rights,
     real   estate   investment   trusts,   convertible   securities,   and  in
     nonconvertible debt securities when we believe these securities will offer
     a good  prospect  for  appreciation.  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.

     As a temporary defensive measure because of market,  economic,  political,
     or other  conditions,  we may  invest up to 100% of the  Fund's  assets in
     investment-grade, short-term debt instruments. This may result in the Fund
     not  achieving  its  investment  objective  during  the time it is in this
     temporary defensive posture.

                                       5
<PAGE>
[CAUTION LIGHT]
MARKET RISK. Because this Fund invests in stocks, it is subject to stock market
risk. Stock prices in general may decline over short or even extended  periods,
regardless of the success or failure of a company's  operations.  Stock markets
tend to run in cycles, with periods when stock prices generally go up, known as
"bull" markets, and periods when stock prices generally go down, referred to as
"bear" markets. Stocks tend to go up and down more than bonds.

 Q   How will particular securities be selected?

 A   We look for stocks of  companies  we believe are  superior but whose share
     prices do not reflect this. Generally, we will invest the Fund's assets in
     stocks that,  at the time of  purchase,  are  considered  out of favor and
     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.

     Using these criteria, we shall attempt to build a portfolio of stocks that
     are  undervalued at the time of purchase,  but which we believe in a short
     time will return to and sustain a normal valuation.

     At times it is likely to be difficult or impossible  for us to find stocks
     in sufficient  quantity that conform to these  criteria.  In such cases we
     will also invest the Fund's assets in other growth stocks.

 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]

FOREIGN  INVESTING  RISK.  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.

                                       6
<PAGE>
 Q   How are the decisions to buy and sell securities made?

 A   We generally purchase  out-of-favor  growth stocks.  However, at times, it
     may be difficult to find a sufficiently varied group of such companies. In
     such cases, we will invest a portion of the Fund's assets in a diversified
     group of large  capitalization  growth  stocks.  Stocks  are sold  when we
     believe they are overvalued.  Overvaluation  is generally caused either by
     earnings  forecasts that are too optimistic or unrealistic  multiples that
     the market places on projected earnings.

For additional  information  about other  securities in which we may invest the
Fund's assets, see APPENDIX A on page 19.

FUND MANAGEMENT

USAA Investment  Management  Company,  serves as the manager and distributor of
this  Fund.  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  $40   billion in total  assets  under
management.  Our mailing address is 9800  Fredericksburg  Road, San Antonio, TX
78288.

We provide management  services to the Fund pursuant to an Advisory  Agreement.
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 Fund's Board of Directors.  For our services,  the Fund pays
us an  annual  fee.  This fee was  computed  and paid at  three-fourths  of one
percent  (.75%) of average net assets for the fiscal year ended July 31,  1999.
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.

                                       8
<PAGE>

For example,  assume you wish to invest in a widely  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 to fit your
own risk and reward goals.

III. USAA's Family of Funds

We offer you  another  alternative  with our  asset  strategy  funds  listed in
APPENDIX B under asset allocation on page 20. These unique mutual funds provide
a  professionally  managed,  diversified  investment  portfolio within a mutual
fund.  Designed for the individual who prefers to delegate the asset allocation
process to an investment  manager,  their  structure  achieves  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 member service
representatives  stand  ready to assist you with your  choices  and to help you
craft a  portfolio  to meet your  needs.  Refer to  APPENDIX B on page 20 for a
complete list of the USAA Family of No-Load Mutual Funds.

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),  phone,  or Internet.  A
complete, signed application is required to open your initial account. However,
after  you open your  initial  account  with us,  you will not need to fill out
another  application  to invest in  another  Fund  unless the  registration  is
different.

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.  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

                                       9
<PAGE>
Exchange  (NYSE)  each day the NYSE is open.  If we receive  your  request  and
payment  prior to that  time,  your  purchase  price  will be the NAV per share
determined  for that day. If we receive your  request or payment  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.
This will avoid a potential  four- to six-week  delay in the effective  date of
your  purchase.  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), your redemption will be effective on the next business day.

We will send you your  money  within  seven days  after the  effective  date of
redemption.  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.  For federal
income tax purposes,  a redemption  is a taxable  event;  and as such,  you may
realize a capital gain or loss.  Such capital  gains or losses are based on the
difference  between your cost basis in the shares and the price  received  upon
redemption.

In addition, the Fund 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
[INVESTOR'S GUIDE GRAPHIC]

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 assist 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

USAA Shareholder  Account Services (SAS), the Fund's transfer agent, may assess
annually a small balance account fee of $12 to each shareholder  account with a
balance  of less than  $2,000 at the time of  assessment.  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).

Fund Rights

The Fund reserves the right to:

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

o   limit or  discontinue  the offering of shares of the Fund 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 Fund's Board
    of Directors and the required notice has been given to shareholders;

                                      13
<PAGE>
o   require a  signature  guarantee  for  transactions  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 ten 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.  Exchanges  made through USAA  TouchLine(R)
and the Internet  require an ESA and EFT Buy/Sell  authorization on file. After
we receive the exchange orders,  the Fund's transfer agent will  simultaneously
process exchange redemptions and purchases at the share prices next determined.
The investment  minimums applicable to share purchases also apply to exchanges.
For federal income tax purposes,  an exchange between Funds is a taxable event;
and as such,  you may realize a capital  gain or loss.  Such  capital  gains or
losses are based on the  difference  between  your cost basis in the shares and
the price received upon exchange.

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

[SIDEBAR]
     NAV PER SHARE EQUALS TOTAL ASSETS MINUS  LIABILITIES  DIVIDED BY # OF
     SHARES OUTSTANDING

The price at which you  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.  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>
Portfolio  securities,  except  as  otherwise  noted,  traded  primarily  on  a
securities exchange are valued at the last sales price on that exchange.  If no
sale is reported, the average of the bid and asked prices is generally used.

Over-the-counter securities are generally priced at the last sales price or, if
not available, at the average of the bid and asked prices.

Debt  securities  purchased  with  maturities  of 60 days or less are stated at
amortized  cost,  which  approximates  market value.  Other debt securities are
valued each  business  day at their  current  market value as  determined  by a
pricing  service  approved by the Fund's Board of  Directors.  Securities  that
cannot be valued by these  methods,  and all other  assets,  are valued in good
faith  at fair  value  using  methods  we have  determined  under  the  general
supervision of the Fund's Board of Directors.

For  additional  information  on how  securities  are valued,  see VALUATION OF
SECURITIES in the Fund's Statement of Additional Information.

Dividends and Distributions

The Fund pays net  investment  income  dividends  yearly.  Any net capital gain
distribution  usually  occurs  within 60 days of the July 31  fiscal  year end,
which  would be  somewhere  around  the end of  September.  The Fund  will make
additional payments to shareholders,  if necessary,  to avoid the imposition of
any federal income or excise tax.

We  will   automatically   reinvest  all  income  dividends  and  capital  gain
distributions  in the Fund unless you instruct us differently.  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.  You should  consider
carefully  the  effects of  purchasing  shares of the Fund  shortly  before any
dividend or distribution.  Some or all of 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 Taxpayer
Relief  Act  of  1997  and  the  technical   provisions   adopted  by  the  IRS
Restructuring  and Reform Act of 1998 may  affect the status and  treatment  of
certain distributions shareholders receive from the Fund.

                                      15
<PAGE>
Because each investor's tax  circumstances  are unique and because the tax laws
are subject to change,  we recommend  that you consult  your tax adviser  about
your investment.

SHAREHOLDER - Dividends from taxable net investment income and distributions of
net  short-term  capital gains are taxable to you 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.

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 information to you annually concerning the tax
status of dividends and distributions for federal income tax purposes.

                                      16

Year 2000

Like other organizations around the world, the Fund could be adversely affected
if the computer systems used by the Fund, its service  providers,  or companies
in which the Fund invests do not  properly  process and  calculate  information
that relates to dates beginning on January 1, 2000, and beyond.  This situation
may occur because for many years computer  programmers  used only two digits to
describe  years,  such as 98 for 1998. A program written in this manner may not
work when it encounters the year 00. To confront this situation, USAA companies
have  spent  much  effort and money;  and we are  confident  that our  critical
systems  are  essentially  prepared  for the Year  2000.  In  addition,  we are
actively assessing the Year 2000 readiness of our service providers,  partners,
and companies in whose  securities we invest.  It is not possible for us to say
that you will experience no effect from this situation,  but we can say that we
are making a large effort to avoid ill effects upon our shareholders.

We do believe you are entitled to know with certainty that we will stand behind
your share balance as of the close of business in 1999. When the market reopens
in 2000,  should any computer problem cause a change in the number of shares in
your account, we will return your account to its proper share balance.

                                   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 the Fund's  assets in  convertible  securities,  which are bonds,
preferred stocks, and other securities that pay interest or dividends and offer
the buyer the ability to convert 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  invest  up to 15% of the  Fund's  net  assets  in  securities  that are
illiquid.  Illiquid securities are those securities which cannot be disposed of
in the ordinary course of business,  seven days or less, at  approximately  the
same value at which the Fund has valued the securities.

MONEY MARKET INSTRUMENTS

We may hold a certain  portion of the Fund's assets in  investment-grade,  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,
banker's  acceptances,  and  other  financial  institution  obligations.  These
securities may carry fixed or variable interest rates.

AMERICAN DEPOSITARY RECEIPTS (ADRS)

We may invest the Fund's  assets in ADRs,  which are  foreign  shares held by a
U.S.  bank that issues a receipt  evidencing  ownership.  Dividends are paid in
U.S. dollars.

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

WHAT IS THE FUND'S INVESTMENT
OBJECTIVE AND MAIN STRATEGY?

The Fund's investment objectives are capital growth and current income. We will
attempt to achieve these objectives by investing the Fund's assets primarily in
dividend-paying equity securities.

In view of the risks inherent in all  investments  in  securities,  there is no
assurance that the Fund's objectives will be achieved.  See FUND INVESTMENTS on
page 5 for more information.

MAIN RISKS OF INVESTING IN THIS FUND

The primary risk of investing in this Fund is market risk.

o    MARKET  RISK  involves  the  possibility  that  the  value  of the  Fund's
     investments  in equity  securities  will  decline in a down stock  market,
     regardless of the success or failure of any one company's operations.

Other risks of the Fund described later in the Prospectus  include the risks of
foreign investing and investing in real estate  investment  trusts (REITs).  As
with other mutual funds, losing money is also a risk of investing in this Fund.

As you consider an investment  in this 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 the  investment  for long periods of time
to ride out down periods.

An  investment  in this Fund is not a deposit of USAA Federal  Savings Bank, or
any other  bank,  and is not  insured  or  guaranteed  by the  Federal  Deposit
Insurance Corporation or any other government agency.

[CAUTION LIGHT]

Look for this symbol throughout the Prospectus. We use it to mark more detailed
information about the risks you will face as a Fund shareholder.

IS THIS FUND FOR YOU?

This Fund might be appropriate as part of your investment portfolio if . . .

   o You are looking for capital growth and current income.
   o You are willing to accept moderate risk.
   o You are looking for a long-term investment.

                                       2
<PAGE>
This Fund may not be appropriate as part of your investment portfolio if . . .

   o You need an investment that provides tax-free income.

This  Fund by  itself  does  not  constitute  a  balanced  investment  program.
Diversifying  your investments may improve your long-run  investment return and
lower the volatility of your overall investment portfolio.

COULD THE VALUE OF YOUR INVESTMENT
IN THIS FUND FLUCTUATE?

Yes,  it  could.  In fact,  the  value of your  investment  in this  Fund  will
fluctuate with the changing  market values of the  investments in the Fund. The
bar chart, shown below,  illustrates the Fund's volatility and performance from
year to year over the life of the Fund.

Total Return

[SIDEBAR]
     TOTAL RETURN MEASURES THE PRICE CHANGE IN A SHARE ASSUMING THE
     REINVESTMENT OF ALL DIVIDEND INCOME AND CAPITAL GAIN DISTRIBUTIONS.

FUND INVESTMENTS

Principal Investment Strategies and Risks

 Q   What is the Fund's principal investment strategy?

 A   The Fund's principal strategy is the investment of its assets primarily in
     dividend-paying equity securities.  We use the term "equity securities" to
     include  common  stocks,   securities   convertible  into  common  stocks,
     securities  that 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 convertible
     debt securities and nonconvertible preferred stock.

     As a temporary defensive measure because of market,  economic,  political,
     or other  conditions,  we may  invest up to 100% of the  Fund's  assets in
     investment-grade, short-term debt instruments. This may result in the Fund
     not  achieving  its  investment  objective  during  the time it is in this
     temporary defensive posture.

                                       5
<PAGE>
[CAUTION LIGHT]
MARKET RISK. Because this Fund invests in equity  securities,  it is subject to
stock  market  risk.  Stock  prices in general may  decline  over short or even
extended  periods,  regardless  of  the  success  or  failure  of  a  company's
operations. Stock markets tend to run in cycles, with periods when stock prices
generally  go up,  known as "bull"  markets,  and  periods  when  stock  prices
generally go down, referred to as "bear" markets.  Equity securities tend to go
up and down more than bonds.

[CAUTION LIGHT]
REITS.  Investing  in REITs  may  subject  the  Fund to many of the same  risks
associated with the direct  ownership of real estate.  Additionally,  REITs are
dependent  upon  the  capabilities  of  the  REIT   manager(s),   have  limited
diversification, and could be significantly impacted by changes in tax laws.

 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]

FOREIGN INVESTING RISK. 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.

 Q   How are the decisions to buy and sell securities made?

 A   We appraise a stock's  price in relation to the company's  earnings,  cash
     flow, book value, and yield. We also consider various  qualitative factors
     such as the number of shares the company's  management  owns, the attitude
     of investors in general toward the company, and the quality of management.

     We use the same  criteria  in  deciding  which  securities  to  sell.  For
     example, when a company's shares sell well above their relative historical
     levels of valuation, we may decide to sell the stock.

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

FUND MANAGEMENT

USAA  Investment  Management  Company serves as the manager and  distributor of
this  Fund.  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  $40   billion in total  assets  under
management.  Our mailing address is 9800  Fredericksburg  Road, San Antonio, TX
78288.

We provide management  services to the Fund pursuant to an Advisory  Agreement.
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 Fund's 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,  1999.  We also
provide   services  related  to  selling  the  Fund's  shares  and  receive  no
compensation for those services.

Portfolio Transactions

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

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

                                       7
<PAGE>
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 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 to fit your own risk and reward goals.

III. USAA's Family of Funds

We offer you  another  alternative  with our  asset  strategy  funds  listed in
APPENDIX B under asset allocation on page 19. These unique mutual funds provide
a  professionally  managed,  diversified  investment  portfolio within a mutual
fund.  Designed for the individual who prefers to delegate the asset allocation
process to an investment  manager,  their  structure  achieves  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 member service
representatives  stand  ready to assist you with your  choices  and to help you
craft a  portfolio  to meet your  needs.  Refer to  APPENDIX B on page 19 for a
complete list of the USAA Family of No-Load Mutual Funds.

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),  phone,  or Internet.  A
complete, signed application is required to open your initial account. However,
after  you open your  initial  account  with us,  you will not need to fill out
another  application  to invest in  another  fund  unless the  registration  is
different.

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.  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  and  payment  prior to that time,  your
purchase price will be the NAV per share determined for that day. If we receive
your  request or payment  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.
This will avoid a potential  four- to six-week  delay in the effective  date of
your  purchase.  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
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), your redemption will be effective on the next business day.

We will send you your  money  within  seven days  after the  effective  date of
redemption.  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.  For federal
income tax purposes,  a redemption  is a taxable  event;  and as such,  you may
realize a capital gain or loss.  Such capital  gains or losses are based on the
difference  between your cost basis in the shares and the price  received  upon
redemption.

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

Account Balance

USAA Shareholder  Account Services (SAS), the Fund's transfer agent, may assess
annually a small balance account fee of $12 to each shareholder  account with a
balance  of less than  $2,000 at the time of  assessment.  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).

Fund Rights

The Fund reserves the right to:

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

o   limit or  discontinue  the offering of shares of the Fund 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 Fund's Board
    of Directors and the required notice has been given to shareholders;

o   require a  signature  guarantee  for  transactions  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 ten 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.  Exchanges  made through USAA  TouchLine(R)
and the Internet  require an ESA and EFT Buy/Sell  authorization on file. After
we receive the exchange orders, the

                                      13
<PAGE>
Fund's  transfer agent will  simultaneously  process  exchange  redemptions and
purchases  at  the  share  prices  next  determined.  The  investment  minimums
applicable to share  purchases also apply to exchanges.  For federal income tax
purposes,  an exchange  between Funds is a taxable event;  and as such, you may
realize a capital gain or loss.  Such capital  gains or losses are based on the
difference  between your cost basis in the shares and the price  received  upon
exchange.

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

[SIDEBAR]
     NAV PER SHARE EQUALS TOTAL ASSETS MINUS LIABILITIES DIVIDED BY # OF
     SHARES OUTSTANDING

The price at which you  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.  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.

Portfolio  securities,  except  as  otherwise  noted,  traded  primarily  on  a
securities exchange are valued at the last sales price on that exchange.  If no
sale is reported, the average of the bid and asked prices is generally used.

Over-the-counter securities are generally priced at the last sales price or, if
not available, at the average of the bid and asked prices.

Debt  securities  purchased  with  maturities  of 60 days or less are stated at
amortized  cost,  which  approximates  market value.  Other debt securities are
valued each  business  day at their  current  market value as  determined  by a
pricing  service  approved by the Fund's Board of  Directors.  Securities  that
cannot be valued by these  methods,  and all other  assets,  are valued in good
faith  at fair  value  using  methods  we have  determined  under  the  general
supervision of the Fund's Board of Directors.

For  additional  information  on how  securities  are valued,  see VALUATION OF
SECURITIES in the Fund's Statement of Additional Information.

                                      14
<PAGE>
Dividends and Distributions

The Fund pays net  investment  income  dividends  yearly.  Any net capital gain
distribution  usually  occurs  within 60 days of the July 31  fiscal  year end,
which  would be  somewhere  around  the end of  September.  The Fund  will make
additional payments to shareholders,  if necessary,  to avoid the imposition of
any federal income or excise tax.

We  will   automatically   invest  all  income   dividends   and  capital  gain
distributions  in the fund unless you instruct us differently.  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.  You should  consider
carefully  the  effects of  purchasing  shares of the Fund  shortly  before any
dividend or distribution.  Some or all of 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 Taxpayer
Relief  Act  of  1997  and  the  technical   provisions   adopted  by  the  IRS
Restructuring  and Reform Act of 1998 may  affect the status and  treatment  of
certain  distributions   shareholders  receive  from  the  Fund.  Because  each
investor's tax circumstances are unique and because the tax laws are subject to
change, we recommend that you consult your tax adviser about your investment.

SHAREHOLDER - Dividends from taxable net investment income and distributions of
net  short-term  capital gains are taxable to you 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.

                                      15
<PAGE>
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 information to you annually concerning the tax
status of dividends and distributions for federal income tax purposes.

Year 2000

Like other organizations around the world, the Fund could be adversely affected
if the computer systems used by the Fund, its service  providers,  or companies
in which the Fund invests do not  properly  process and  calculate  information
that relates to dates beginning on January 1, 2000, and beyond.  This situation
may occur because for many years computer  programmers  used only two digits to
describe  years,  such as 98 for 1998. A program written in this manner may not
work when it encounters the year 00. To confront this situation, USAA companies
have  spent  much  effort and money;  and we are  confident  that our  critical
systems  are  essentially  prepared  for the Year  2000.  In  addition,  we are
actively assessing the Year 2000 readiness of our service providers,  partners,
and companies in whose  securities we invest.  It is not possible for us to say
that you will experience no effect from this situation,  but we can say that we
are making a large effort to avoid ill effects upon our shareholders.

We do believe you are entitled to know with certainty that we will stand behind
your share balance as of the close of business in 1999. When the market reopens
in 2000,  should any computer problem cause a change in the number of shares in
your account, we will return your account to its proper share balance.

                                   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 the Fund's  assets in  convertible  securities,  which are bonds,
preferred stocks, and other securities that pay interest or dividends and offer
the buyer the ability to convert 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  invest  up to 15% of the  Fund's  net  assets  in  securities  that are
illiquid.  Illiquid securities are those securities which cannot be disposed of
in the ordinary course of business,  seven days or less, at  approximately  the
same value at which the Fund has valued the securities.

MONEY MARKET INSTRUMENTS

We may hold a certain  portion of the Fund's assets in  investment-grade,  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,
banker's  acceptances,  and  other  financial  institution  obligations.  These
securities may carry fixed or variable interest rates.

AMERICAN DEPOSITARY RECEIPTS (ADRS)

We may invest the Fund's  assets in ADRs,  which are  foreign  shares held by a
U.S.  bank that issues a receipt  evidencing  ownership.  Dividends are paid in
U.S. dollars.

WHAT IS THE FUND'S INVESTMENT
OBJECTIVE AND MAIN STRATEGY?

The  Fund's  investment  objective  is  current  income  with the  prospect  of
increasing dividend income and the potential for capital appreciation.  We will
attempt to achieve this  objective by investing the Fund's assets  primarily in
common stocks of well-established,  large companies with above-average dividend
yields.

In view of the risks inherent in all  investments  in  securities,  there is no
assurance that the Fund's  objective will be achieved.  See FUND INVESTMENTS on
page 6 for more information.

MAIN RISKS OF INVESTING IN THIS FUND

The primary  risks of  investing in this Fund are market  risk,  interest  rate
risk, and credit risk.

o    MARKET  RISK  involves  the  possibility  that  the  value  of the  Fund's
     investments  in equity  securities  will  decline in a down stock  market,
     regardless of the success or failure of any one company's operations.

o    INTEREST RATE RISK involves the  possibility  that the value of the Fund's
     investments will fluctuate because of changes in interest rates.

     IF INTEREST  RATES  INCREASE:  the yield of the Fund may  increase and the
     market  value of the Fund's  securities  will  likely  decline,  adversely
     affecting the net asset value and total return.

     IF INTEREST  RATES  DECREASE:  the yield of the Fund may  decrease and the
     market value of the Fund's  securities  may  increase,  which would likely
     increase the Fund's net asset value and total return.

o    CREDIT RISK involves the  possibility  that a borrower  cannot make timely
     interest and principal payments on its securities.

Another  risk of the  Fund  described  later in the  Prospectus  is the risk of
foreign investing.  As with other mutual funds,  losing money is also a risk of
investing in this Fund.

As you consider an investment  in this 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 the  investment  for long periods of time
to ride out down periods.

An  investment  in this Fund is not a deposit of USAA Federal  Savings Bank, or
any other  bank,  and is not  insured  or  guaranteed  by the  Federal  Deposit
Insurance Corporation or any other government agency.

FUND INVESTMENTS

Principal Investment Strategies and Risks

 Q   What is the Fund's principal investment strategy?

 A   The Fund's principal strategy is the investment of its assets primarily in
     the  common  stocks  of   well-established,   large  companies  that  have
     demonstrated an ability to increase their dividends. We attempt to provide
     a portfolio  with a dividend yield above the average of the S&P 500 Index.
     We may include  common  stocks,  real estate  investment  trusts  (REITs),
     securities  convertible into common stocks,  and securities that carry the
     right to buy common stocks in the portfolio.

     As a temporary defensive measure because of market,  economic,  political,
     or other  conditions,  we may  invest up to 100% of the  Fund's  assets in
     investment-grade, short-term debt instruments. This may result in the Fund
     not  achieving  its  investment  objective  during  the time it is in this
     temporary defensive posture.

[CAUTION LIGHT]
MARKET  RISK.  Because  this Fund  invests  in  stocks,  including  convertible
securities,  it is subject to stock  market  risk.  Stock prices in general may
decline  over short or even  extended  periods,  regardless  of the  success or
failure of a company's  operations.  Stock markets tend to run in cycles,  with
periods when stock prices generally go up, known as "bull" markets, and periods
when stock prices generally go down, referred to as "bear" markets.
Stocks tend to go up and down more than bonds.

[CAUTION LIGHT]
REITS.  Investing  in REITs  may  subject  the  Fund to many of the same  risks
associated with the direct  ownership of real estate.  Additionally,  REITs are
dependent  upon  the  capabilities  of  the  REIT   manager(s),   have  limited
diversification, and could be significantly impacted by changes in tax laws.

                                       6
<PAGE>
 Q   Are there any limitations on how much of the Fund's assets may be invested
     in any particular securities?

 A   We may only  invest  up to 25% of the  Fund's  net  assets  in  securities
     convertible  into  common  stocks  measured  at  the  time a  security  is
     purchased.  These  convertible  securities  may be rated below  investment
     grade as  determined  by Moody's  Investors  Service or  Standard & Poor's
     Ratings Group or may be unrated.

[CAUTION LIGHT]
INTEREST  RATE RISK.  Interest  rate risk is the risk that the market  value of
certain  securities will decline because of rising interest rates.  Some of the
Fund's portfolio  securities have similar interest rate risk characteristics to
bonds.  In general,  when interest rates rise,  the prices of these  securities
fall and when interest  rates fall,  the prices of these  securities  generally
rise.

[CAUTION LIGHT]
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 because of 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]

FOREIGN  INVESTING  RISKS.  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.

                                       7
<PAGE>
 Q   How are the decisions to buy and sell securities made?

 A   We normally  evaluate a universe of stocks with a dividend  stream growing
     faster than the average company.  A stock is selected based on independent
     research of the following:

     o the quality of management,
     o industry fundamentals, and
     o the company's future prospects.

     These  factors  are  combined  with an  attractive  valuation  to make the
     purchase decision.  We sell a stock when one or more of the factors change
     for the worse.

For additional  information  about other  securities in which we may invest the
Fund's assets, see APPENDIX A on page 20.

FUND MANAGEMENT

USAA  Investment  Management  Company serves as the manager and  distributor of
this  Fund.  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  $40   billion in total  assets  under
management.  Our mailing address is 9800  Fredericksburg  Road, San Antonio, TX
78288.

We provide management  services to the Fund pursuant to an Advisory  Agreement.

brokerage  orders) and its business  affairs,  subject to the  authority of and
supervision by the Fund's Board of Directors.  For our services,  the Fund pays

(.50%) of average net assets for the fiscal year ended July 31,  1999.  We also
provide   services  related  to  selling  the  Fund's  shares  and  receive  no
compensation for those services.

Portfolio Transactions

USAA Brokerage Services,  our discount brokerage service, may execute purchases
and sales of equity  securities for the Fund's  portfolio.  The Fund's Board of

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 emphasizing capital appreciation as their primary objective.  This is
just one way you could combine funds to fit your own risk and reward goals.

III. USAA's Family of Funds

We offer you  another  alternative  with our  asset  strategy  funds  listed in

a  professionally  managed,  diversified  investment  portfolio within a mutual
fund.  Designed for the individual who prefers to delegate the asset allocation
process to an investment  manager,  their  structure  achieves  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 member service
representatives  stand  ready to assist you with your  choices  and to help you
craft a  portfolio  to meet your  needs.  Refer to  APPENDIX B on page 21 for a
complete list of the USAA Family of No-Load Mutual Funds.

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),  phone,  or Internet.  A
complete, signed application is required to open your initial account. However,
after  you open your  initial  account  with us,  you will not need to fill out
another  application  to invest in  another  Fund  unless the  registration  is
different.

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.  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  and  payment  prior to that time,  your
purchase price will be the NAV per share determined for that day. If we receive
your  request or payment  after the NAV per share is  calculated,  the purchase
will be effective on the next business day.

                                      10
<PAGE>

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.
This will avoid a potential  four- to six-week  delay in the effective  date of
your  purchase.  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), your redemption will be effective on the next business day.

We will send you your  money  within  seven days  after the  effective  date of
redemption.  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.  For federal
income tax purposes,  a redemption  is a taxable  event;  and as such,  you may
realize a capital gain or loss.  Such capital  gains or losses are based on the
difference  between your cost basis in the shares and the price  received  upon
redemption.

In addition, the Fund 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
[INVESTOR'S GUIDE GRAPHIC]

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 assist 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

USAA Shareholder  Account Services (SAS), the Fund's transfer agent, may assess
annually a small balance account fee of $12 to each shareholder  account with a
balance  of less than  $2,000 at the time of  assessment.  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).

Fund Rights

The Fund reserves the right to:

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

o   limit or  discontinue  the offering of shares of the Fund 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

                                      14
<PAGE>
    unless  authorized by the Fund's Board of Directors and the required notice
    has been given to shareholders;

o   require a  signature  guarantee  for  transactions  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 ten 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.  Exchanges  made through USAA  TouchLine(R)
and the Internet  require an ESA and EFT Buy/Sell  authorization on file. After
we receive the exchange orders,  the Fund's transfer agent will  simultaneously
process exchange redemptions and purchases at the share prices next determined.
The investment  minimums applicable to share purchases also apply to exchanges.
For federal income tax purposes,  an exchange between Funds is a taxable event;
and as such,  you may realize a capital  gain or loss.  Such  capital  gains or
losses are based on the  difference  between  your cost basis in the shares and
the price received upon exchange.

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

[SIDEBAR]
     NAV PER SHARE EQUALS TOTAL ASSETS MINUS LIABILITIES DIVIDED BY # OF
     SHARES OUTSTANDING

The price at which you  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

                                      15
<PAGE>
share  without a sales  charge.  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.

Portfolio  securities,  except  as  otherwise  noted,  traded  primarily  on  a
securities exchange are valued at the last sales price on that exchange.  If no
sale is reported, the average of the bid and asked prices is generally used.

Over-the-counter securities are generally priced at the last sales price or, if
not available, at the average of the bid and asked prices.

Debt  securities  purchased  with  maturities  of 60 days or less are stated at
amortized  cost,  which  approximates  market value.  Other debt securities are
valued each  business  day at their  current  market value as  determined  by a
pricing  service  approved by the Fund's Board of  Directors.  Securities  that
cannot be valued by these  methods,  and all other  assets,  are valued in good
faith  at fair  value  using  methods  we have  determined  under  the  general
supervision of the Fund's Board of Directors.

For  additional  information  on how  securities  are valued,  see VALUATION OF
SECURITIES in the Fund's Statement of Additional Information.

Dividends and Distributions

The Fund pays net  investment  income  dividends  yearly.  Any net capital gain
distribution  usually  occurs  within 60 days of the July 31  fiscal  year end,
which  would be  somewhere  around  the end of  September.  The Fund  will make
additional payments to shareholders,  if necessary,  to avoid the imposition of
any federal income or excise tax.

We  will   automatically   reinvest  all  income  dividends  and  capital  gain
distributions  in the Fund unless you instruct us differently.  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.  You should  consider
carefully  the  effects of  purchasing  shares of the Fund  shortly  before any
dividend or distribution.  Some or all of 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.

                                      16

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 Taxpayer
Relief  Act  of  1997  and  the  technical   provisions   adopted  by  the  IRS
Restructuring  and Reform Act of 1998 may  affect the status and  treatment  of
certain  distributions   shareholders  receive  from  the  Fund.  Because  each
investor's tax circumstances are unique and because the tax laws are subject to
change, we recommend that you consult your tax advisor about your investment.

SHAREHOLDER - Dividends from taxable net investment income and distributions of
net  short-term  capital gains are taxable to you 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.

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 information to you annually concerning the tax
status of dividends and distributions for federal income tax purposes.

                                      17

Year 2000

Like other organizations around the world, the Fund could be adversely affected
if the computer systems used by the Fund, its service  providers,  or companies
in which the Fund invests do not  properly  process and  calculate  information
that relates to dates beginning on January 1, 2000, and beyond.  This situation
may occur because for many years computer  programmers  used only two digits to
describe  years,  such as 98 for 1998. A program written in this manner may not
work when it encounters the year 00. To confront this situation, USAA companies
have  spent  much  effort and money;  and we are  confident  that our  critical
systems  are  essentially  prepared  for the Year  2000.  In  addition,  we are
actively assessing the Year 2000 readiness of our service providers,  partners,
and companies in whose  securities we invest.  It is not possible for us to say
that you will experience no effect from this situation,  but we can say that we
are making a large effort to avoid ill effects upon our shareholders.

We do believe you are entitled to know with certainty that we will stand behind
your share balance as of the close of business in 1999. When the market reopens
in 2000,  should any computer problem cause a change in the number of shares in
your account, we will return your account to its proper share balance.

FINANCIAL HIGHLIGHTS

The financial  highlights  table is intended to help you  understand the Fund's
financial  performance for the past five years.  Certain  information  reflects
financial  results  for a single  Fund  share.  The total  returns in the table
represent  the  rate  that an  investor  would  have  earned  (or  lost)  on an
investment  in  this  Fund   (assuming   reinvestment   of  all  dividends  and
distributions).  This  information  has been audited by KPMG LLP, whose report,
along with the Fund's financial statements,  are included in the Annual Report,

                                   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 the Fund's  assets in  convertible  securities,  which are bonds,
preferred stocks, and other securities that pay interest or dividends and offer
the buyer the ability to convert 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  invest  up to 15% of the  Fund's  net  assets  in  securities  that are
illiquid.  Illiquid securities are those securities which cannot be disposed of
in the ordinary course of business,  seven days or less, at  approximately  the
same value at which the Fund has valued the securities.

MONEY MARKET INSTRUMENTS

We may hold a certain  portion of the Fund's assets in  investment-grade,  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,
banker's  acceptances,  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.

AMERICAN DEPOSITARY RECEIPTS (ADRS)

We may invest the Fund's  assets in ADRs,  which are  foreign  shares held by a
U.S.  bank that issues a receipt  evidencing  ownership.  Dividends are paid in
U.S. dollars.

the Prospectus.

WHAT IS THE FUND'S INVESTMENT
OBJECTIVE AND MAIN STRATEGY?

The Fund's investment objective is maximum current income without undue risk to
principal.  We will attempt to achieve this  objective by investing  the Fund's
assets primarily in income-producing securities.

In view of the risks inherent in all  investments  in  securities,  there is no
assurance that the Fund's  objective will be achieved.  See FUND INVESTMENTS on
page 6 for more information.

MAIN RISKS OF INVESTING IN THIS FUND

The primary risks of investing in this Fund are interest rate risk,  prepayment
risk, credit risk, and market risk.

o   INTEREST  RATE RISK involves the  possibility  that the value of the Fund's
    investments will fluctuate because of changes in interest rates.

    IF INTEREST  RATES  INCREASE:  the yield of the Fund may  increase  and the
    market  value of the  Fund's  securities  will  likely  decline,  adversely
    affecting the net asset value and total return.

    IF INTEREST  RATES  DECREASE:  the yield of the Fund may  decrease  and the
    market  value of the Fund's  securities  may  increase,  which would likely
    increase the Fund's net asset value and total return.

o   PREPAYMENT RISK involves the possibility  that  prepayments of mortgages in
    the Fund's  portfolio will require  reinvestment  at lower interest  rates,
    resulting in less interest income to the Fund.

o   CREDIT RISK  involves the  possibility  that a borrower  cannot make timely
    interest and principal payments on its securities.

o   MARKET  RISK  involves  the  possibility  that  the  value  of  the  Fund's
    investments  in equity  securities  will  decline in a down  stock  market,
    regardless of the success or failure of any one company's operations.

Another  risk of the  Fund  described  later in the  Prospectus  is the risk of
investing in real estate investment trusts. As with other mutual funds,  losing
money is also a risk of investing in this Fund.

As you consider an investment  in this 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 the  investment  for long periods of time
to ride out down periods.

                                       2

An  investment  in this Fund is not a deposit of USAA Federal  Savings Bank, or
any other  bank,  and is not  insured  or  guaranteed  by the  Federal  Deposit
Insurance Corporation or any other government agency.

[CAUTION LIGHT]

Look for this symbol throughout the Prospectus. We use it to mark more detailed
information about the risks you will face as a Fund shareholder.

IS THIS FUND FOR YOU?

This Fund might be appropriate as part of your investment portfolio if . . .

   o You need steady income.
   o You are willing to accept moderate risk.
   o You are looking for a long-term investment.

This Fund may not be appropriate as part of your investment portfolio if . . .

   o Your primary goal is to maximize long-term growth.

   o You need an investment that provides tax-free income.

This  Fund by  itself  does  not  constitute  a  balanced  investment  program.
Diversifying  your investments may improve your long-run  investment return and
lower the volatility of your overall investment portfolio.

COULD THE VALUE OF YOUR INVESTMENT
IN THIS FUND FLUCTUATE?

Yes,  it  could.  In fact,  the  value of your  investment  in this  Fund  will
fluctuate with the changing  market values of the  investments in the Fund. The
bar chart, shown below,  illustrates the Fund's volatility and performance from
year to year over the past ten years.

FUND INVESTMENTS

Principal Investment Strategies and Risks

 Q   What is the Fund's principal investment strategy?

 A   The Fund's principal strategy is the investment of its 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 because of market,  economic,  political,
     or other  conditions,  we may  invest up to 100% of the  Fund's  assets in
     investment-grade, short-term debt instruments. This may result in the Fund
     not  achieving  its  investment  objective  during  the time it is in this
     temporary defensive posture.

[CAUTION LIGHT]
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  because of rising
interest rates. Bond prices are linked to the prevailing market interest rates.
In general,  when interest rates rise, bond prices fall and when interest rates
fall,  bond prices  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.

[CAUTION LIGHT]
PREPAYMENT  RISK.  Mortgagors may generally pay off mortgages  without  penalty
before the due date.  When mortgaged  property is sold,  which can occur at any
time for a variety of reasons, the old mortgage is usually prepaid.  Also, when
mortgage  interest  rates  fall  far  enough  to make  refinancing  attractive,
prepayments  tend  to  accelerate.  Prepayments  require  reinvestment  of  the
principal at the  then-current  level of interest  rates,  which are often at a
lower level than when the mortgages were  originally  issued.  Reinvestment  at
lower rates  tends to reduce the  interest  payments  received by the Fund and,
therefore,  the size of the dividend  payments  available to  shareholders.  If
reinvestment occurs at a higher level of interest rates, the opposite effect is
true.

                                       6
<PAGE>
 Q   What types of 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 agencies 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 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;
     o Yankee obligations;
     o other debt securities;
     o convertible securities;
     o equity and debt securities of real estate investment trusts;
     o common stocks; and
     o preferred stocks.

     For a further description of these securities, see APPENDIX A on page 20.

 Q   What will be the  quality of the debt  securities  included  in the Fund's
     portfolio?

 A   The debt  securities  must be  investment  grade at the time of  purchase.
     Investment-grade  securities are those securities  issued or guaranteed by
     the U.S. government,  its agencies and  instrumentalities;  those rated or
     subject to a guarantee  that is rated  within the four  highest  long-term
     rating categories by:

     o Moody's Investors Service,
     o Standard & Poor's Ratings Group,
     o Fitch IBCA, or
     o Duff and Phelps Credit Rating Co.

     If unrated by these agencies, we must determine that the 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.

                                       7
<PAGE>
[CAUTION LIGHT]
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 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
related to whether interest or principal will be repaid on a timely basis.

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

 A   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 Fund's
     Board of Directors.

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

[CAUTION LIGHT]
 A   MARKET RISK. Because this Fund may invest in equity securities,  it can be
     subject to stock  market  risk.  Stock  prices in general may decline over
     short or even extended periods,  regardless of the success or failure of a
     company's  operations.  Stock markets tend to run in cycles,  with periods
     when stock prices  generally go up, known as "bull"  markets,  and periods
     when stock prices generally go down, referred to as "bear" markets. Equity
     securities tend to go up and down more than bonds.

 Q   How are the decisions to buy and sell securities made?

 A   We search for securities  that  represent  value at the time given current
     market conditions. For fixed income securities,  value is a combination of
     yield, credit quality, structure (maturity,  coupon, redemption features),
     and liquidity. Recognizing value is the result of simultaneously analyzing
     the interaction of these

                                       8
<PAGE>
     factors  among the  securities  available  in the  market.  We will sell a
     security  if we become  concerned  about its  credit  risk,  are forced by
     market factors to raise money,  or an attractive  replacement  security is
     available.   For  common  stocks,   value  involves  selecting  individual
     dividend-paying stocks, whose yields are sensitive to interest rate levels
     when  their  dividend  yields  are  close to bond  yields,  which  implies
     undervaluation. Such stocks are generally sold when their yields return to
     a normal relationship versus bonds through price appreciation.

For additional  information  about other  securities in which we may invest the
Fund's assets, see APPENDIX A on page 20.

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 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 to fit your own risk and
reward goals.

III. USAA's Family of Funds

We offer you  another  alternative  with our  asset  strategy  funds  listed in
APPENDIX B under asset allocation on page 23. These unique mutual funds provide
a  professionally  managed,  diversified  investment  portfolio within a mutual
fund.  Designed for the individual who prefers to delegate the asset allocation
process to an investment  manager,  their  structure  achieves  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

                                      10

choices covering just about any investor's  investment  objectives.  Our member
service representatives stand ready to assist you with your choices and to help
you craft a portfolio to meet your needs.  Refer to APPENDIX B on page 23 for a
complete list of the USAA Family of No-Load Mutual Funds.

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),  phone,  or Internet.  A
complete, signed application is required to open your initial account. However,
after  you open your  initial  account  with us,  you will not need to fill out
another  application  to invest in  another  fund  unless the  registration  is
different.

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.  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  and  payment  prior to that time,  your
purchase price will be the NAV per share determined for that day. If we receive
your  request or payment  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.
This will avoid a potential  four- to six-week  delay in the effective  date of
your  purchase.  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

    electronic  investments  of at least $50 each.  We may  periodically  offer
    programs that reduce the minimum amounts for

                                      11
<PAGE>
    monthly  electronic  investments.  Employees  of USAA  and  its  affiliated

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), your redemption will be effective on the next business day.

We will send you your  money  within  seven days  after the  effective  date of
redemption.  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.  For federal
income tax purposes,  a redemption  is a taxable  event;  and as such,  you may
realize a capital gain or loss.  Such capital  gains or losses are based on the
difference  between your cost basis in the shares and the price  received  upon
redemption.

                                      13

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

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 assist you in
your role as an investor.  In the INVESTOR'S  GUIDE,  you will find  additional

Account Balance

USAA Shareholder  Account Services (SAS), the Fund's transfer agent, may assess
annually a small balance account fee of $12 to each shareholder  account with a
balance  of less than  $2,000 at the time of  assessment.  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).

Fund Rights

The Fund reserves the right to:

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

o   limit or  discontinue  the offering of shares of the Fund 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 Fund's Board
    of Directors and the required notice has been given to shareholders;

o   require a  signature  guarantee  for  transactions  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 ten 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.  Exchanges  made through USAA  TouchLine(R)
and the Internet  require an ESA and EFT

                                      15
<PAGE>
Buy/Sell  authorization  on file.  After we receive the  exchange  orders,  the
Fund's  transfer agent will  simultaneously  process  exchange  redemptions and
purchases  at  the  share  prices  next  determined.  The  investment  minimums
applicable to share  purchases also apply to exchanges.  For federal income tax
purposes,  an exchange  between Funds is a taxable event;  and as such, you may
realize a capital gain or loss.  Such capital  gains or losses are based on the
difference  between your cost basis in the shares and the price  received  upon
exchange.

The Fund has undertaken certain procedures regarding telephone  transactions as
described on page 14.

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

[SIDEBAR]
     NAV PER SHARE EQUALS TOTAL ASSETS MINUS LIABILITIES DIVIDED BY # OF
     SHARES OUTSTANDING

The price at which you  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.  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.

Portfolio  securities,  except  as  otherwise  noted,  traded  primarily  on  a
securities  exchange are valued at the last sale price on that exchange.  If no
sale is reported, the average of the bid and asked prices is generally used.

Over-the-counter securities are generally priced at the last sales price or, if
not available, at the average of the bid and asked prices.

Debt  securities  purchased  with  maturities  of 60 days or less are stated at
amortized  cost,  which  approximates  market value.  Other debt securities are
valued each  business  day at their  current  market value as  determined  by a
pricing  service  approved by the Fund's Board of  Directors.  Securities  that
cannot be valued by these  methods,  and all other  assets,  are valued in good
faith  at fair  value  using  methods  we have  determined  under  the  general
supervision of the Fund's Board of Directors.

For  additional  information  on how  securities  are valued,  see VALUATION OF
SECURITIES in the Fund's Statement of Additional Information.

                                      16

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 gain  distribution  usually  occurs within 60
days of the July 31 fiscal year end, which would be somewhere around the end of
September.  The  Fund  will  make  additional  payments  to  shareholders,   if
necessary, to avoid the imposition of any federal income or excise tax.

We  will   automatically   reinvest  all  income  dividends  and  capital  gain
distributions  in the Fund unless you instruct us differently.  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.  You should  consider
carefully  the  effects of  purchasing  shares of the Fund  shortly  before any
dividend or distribution.  Some or all of 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 Taxpayer
Relief  Act  of  1997  and  the  technical   provisions   adopted  by  the  IRS
Restructuring  and Reform Act of 1998 may  affect the status and  treatment  of
certain  distributions   shareholders  receive  from  the  Fund.  Because  each
investor's tax circumstances are unique and because the tax laws are subject to
change, we recommend that you consult your tax adviser about your investment.

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

                                      17
<PAGE>
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.

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 information to you annually concerning the tax
status of dividends and distributions for federal income tax purposes.

Year 2000

Like other organizations around the world, the Fund could be adversely affected
if the computer systems used by the Fund, its service  providers,  or companies
in which the Fund invests do not  properly  process and  calculate  information
that relates to dates beginning on January 1, 2000, and beyond.  This situation
may occur because for many years computer  programmers  used only two digits to
describe  years,  such as 98 for 1998. A program written in this manner may not
work when it encounters the year 00. To confront this situation, USAA companies
have  spent  much  effort and money;  and we are  confident  that our  critical
systems  are  essentially  prepared  for the Year  2000.  In  addition,  we are
actively assessing the Year 2000 readiness of our service providers,  partners,
and companies in whose  securities we invest.  It is not possible for us to say
that you will experience no effect from this situation,  but we can say that we
are making a large effort to avoid ill effects upon our shareholders.

We do believe you are entitled to know with certainty that we will stand behind
your share balance as of the close of business in 1999. When the market reopens
in 2000,  should any computer problem cause a change in the number of shares in
your account, we will return your account to its proper share balance.

FINANCIAL HIGHLIGHTS

The financial  highlights  table is intended to help you  understand the Fund's
financial  performance for the past five years.  Certain  information  reflects
financial  results  for a single  Fund  share.  The total  returns in the table

                                   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 the  Fund's  assets in  securities  (including  securities  with
variable  interest rates) that 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  the  Fund's   assets  in   repurchase   agreements   that  are
collateralized  by  obligations  issued or guaranteed as to both  principal and
interest  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 the Fund's assets 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    Because the interest rates of variable rate  securities  are  periodically
     adjusted to reflect  current  market  rates,  their  market  value is less
     affected by changes in prevailing  interest rates than the market value of
     securities with fixed interest rates.

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 the Fund's assets 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.

                                      20

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  obligations) as well as dollar-denominated
instruments  that  have been  issued by  foreign  issuers  in the U.S.  capital
markets (Yankee obligations).

                                      21
<PAGE>
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 Fund's 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.

CONVERTIBLE SECURITIES

We may invest the Fund's  assets in  convertible  securities,  which are bonds,
preferred stocks, and other securities that pay interest or dividends and offer
the buyer the ability to convert 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  invest  up to 15% of the  Fund's  net  assets  in  securities  that are
illiquid.  Illiquid securities are those securities which cannot be disposed of
in the ordinary course of business,  seven days or less, at  approximately  the
same value at which the Fund has valued the securities.

REAL ESTATE INVESTMENT TRUSTS (REITS)

We may invest the Fund's assets in REITs, which may subject the Fund to many of
the  same  risks   associated  with  the  direct   ownership  of  real  estate.
Additionally, REITs are dependent upon the capabilities of the REIT manager(s),
have limited diversification, and could be significantly impacted by changes in
tax laws.

the Prospectus.

WHAT IS THE FUND'S INVESTMENT
OBJECTIVE AND MAIN STRATEGY?

The  Fund's  investment  objective  is  high  current  income  consistent  with
preservation  of  principal.  We will  attempt to  achieve  this  objective  by
investing the Fund's assets primarily in a broad range of investment-grade debt
securities.  We will maintain a dollar-weighted  average portfolio  maturity of
three years or less.

In view of the risks inherent in all  investments  in  securities,  there is no
assurance that the Fund's  objective will be achieved.  See FUND INVESTMENTS on
page 6 for more information.

MAIN RISKS OF INVESTING IN THIS FUND

The primary  risks of investing in this Fund are credit risk and interest  rate
risk.

o   CREDIT RISK  involves the  possibility  that a borrower  cannot make timely
    interest and principal payments on its securities.

o   INTEREST  RATE RISK involves the  possibility  that the value of the Fund's
    investments will fluctuate due to changes in interest rates.

    IF INTEREST  RATES  INCREASE:  the yield of the Fund may  increase  and the
    market  value of the  Fund's  securities  will  likely  decline,  adversely
    affecting the net asset value and total return.

    IF INTEREST  RATES  DECREASE:  the yield of the Fund may  decrease  and the
    market  value of the Fund's  securities  may  increase,  which would likely
    increase the Fund's net asset value and total return.

Additional  risks of the Fund described  later in the Prospectus are prepayment
risk and the risk of investing in real estate investment  trusts. As with other
mutual funds, losing money is also a risk of investing in this Fund.

As you consider an investment  in this 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 the  investment  for long periods of time
to ride out down periods.

An  investment  in this Fund is not a deposit of USAA Federal  Savings Bank, or
any other  bank,  and is not  insured  or  guaranteed  by the  Federal  Deposit
Insurance Corporation or any other government agency.

[CAUTION LIGHT]

Look for this symbol throughout the Prospectus. We use it to mark more detailed
information about the risks you will face as a Fund shareholder.

IS THIS FUND FOR YOU?

This Fund might be appropriate as part of your investment portfolio if . . .

   o You are looking for current income.
   o You are looking for an investment that is low risk.
   o You are looking for a short-term investment.

This Fund may not be appropriate as part of your investment portfolio if . . .

   o Your primary goal is to maximize long-term growth.
   o You need a high total return to achieve your goals.
   o You need an investment that provides tax-free income.

This  Fund by  itself  does  not  constitute  a  balanced  investment  program.
Diversifying  your investments may improve your long-run  investment return and
lower the volatility of your overall investment portfolio.

COULD THE VALUE OF YOUR INVESTMENT
IN THIS FUND FLUCTUATE?

Yes,  it  could.  In fact,  the  value of your  investment  in this  Fund  will
fluctuate with the changing  market values of the  investments in the Fund. The
bar chart, shown below,  illustrates the Fund's volatility and performance from
year to year over the life of the Fund.

FUND INVESTMENTS

Principal Investment Strategies and Risks

[SIDEBAR]
     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 THE TOTAL
     BY THE DOLLAR VALUE OF THE FUND'S PORTFOLIO.

 Q   What is the Fund's principal investment strategy?

 A   The Fund's principal strategy is the investment of its 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 types 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  agencies 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 (REITs);
     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;  and
     o other debt securities.

     For a further description of these securities, see APPENDIX A on page 20.

 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 or subject to a guarantee that is rated within the categories listed
     by the following rating agencies:

                                       6
<PAGE>

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

         RATING AGENCY       DEBT SECURITIES      DEBT SECURITIES
     --------------------------------------------------------------
         Moody's Investors                        At least Prime-3
          Service             At least Baa        or MIG4/VMIG4
     --------------------------------------------------------------
         Standard & Poor's                        At least A-3

         Duff and Phelps
          Credit Rating Co.   At least BBB        At least D-3
     ==============================================================

     If unrated by these agencies, we must determine that the 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  below  investment
     grade?

 A   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 Fund's
     Board of Directors.

[CAUTION LIGHT]
CREDIT  RISK.  The bonds in the Fund's  portfolio  are subject to 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 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 related to whether interest or
principal will be repaid on a timely basis.

                                       7
<PAGE>
[CAUTION LIGHT]

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,  bonds prices fall and when interest rates
fall,  bond prices  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.

[CAUTION LIGHT]
PREPAYMENT  RISK.  Mortgagors may generally pay off mortgages  without  penalty
before the due date.  When mortgaged  property is sold,  which can occur at any
time for a variety of reasons, the old mortgage is usually prepaid.  Also, when
mortgage  interest  rates  fall  far  enough  to make  refinancing  attractive,
prepayments  tend  to  accelerate.  Prepayments  require  reinvestment  of  the
principal at the  then-current  level of interest  rates,  which are often at a
lower level than when the mortgages were  originally  issued.  Reinvestment  at
lower rates  tends to reduce the  interest  payments  received by the Fund and,
therefore,  the size of the dividend  payments  available to  shareholders.  If
reinvestment occurs at a higher level of interest rates, the opposite effect is
true.

[CAUTION LIGHT]
REITS.  Investing  in REITs  may  subject  the  Fund to many of the same  risks
associated with the direct  ownership of real estate.  Additionally,  REITs are
dependent  upon  the  capabilities  of  the  REIT   manager(s),   have  limited
diversification,  and could be  significantly  impacted by changes in tax laws.
Moreover,  by  investing  in the debt  securities  of  REITs,  the Fund is also
subject to credit risk.

 Q   How are the decisions to buy and sell securities made?

 A   We search for securities  that  represent  value at the time given current
     market  conditions.  Value is a  combination  of  yield,  credit  quality,
     structure  (maturity,   coupon,   redemption  features),   and  liquidity.
     Recognizing   value  is  the  result  of   simultaneously   analyzing  the
     interaction of these factors among the securities available in the market.
     We will sell a security if we become  concerned about its credit risk, are
     forced by market factors to raise money,  or an attractive  replacement is
     available.

For additional  information  about other  securities in which we may invest the
Fund's assets, see APPENDIX A on page 20.

FUND MANAGEMENT

USAA  Investment  Management  Company serves as the manager and  distributor of
this  Fund.  We are an  affiliate  of United  Services  Automobile  Association

 .22% of average net assets.  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.

                                       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  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 to fit your
own risk and reward goals.

III. USAA's Family of Funds

We offer you  another  alternative  with our  asset  strategy  funds  listed in
APPENDIX B under asset allocation on page 23. These unique mutual funds provide
a  professionally  managed,  diversified  investment  portfolio within a mutual
fund.  Designed for the individual who prefers to delegate the asset allocation
process to an investment  manager,  their  structure  achieves  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 member service
representatives  stand  ready to assist you with your  choices  and to help you
craft a  portfolio  to meet your  needs.  Refer to  APPENDIX B on page 23 for a
complete list of the USAA Family of No-Load Mutual Funds.

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),  phone,  or Internet.  A
complete, signed application is required to open your initial account. However,
after  you open your  initial  account  with us,  you will not need to fill out
another  application  to invest in  another  Fund  unless the  registration  is
different.

                                      10
<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.  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  and  payment  prior to that time,  your
purchase price will be the NAV per share determined for that day. If we receive
your  request or payment  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.
This will avoid a potential  four- to six-week  delay in the effective  date of
your  purchase.  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), your redemption will be effective on the next business day.

We will send you your  money  within  seven days  after the  effective  date of
redemption.  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.  For federal
income tax purposes,  a redemption  is a taxable  event,  and as such,  you may
realize a capital gain or loss.  Such capital  gains or losses are based on the
difference  between your cost basis in the shares and the price  received  upon
redemption.

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

Telephone redemption privileges are automatically established when you complete
your application.  The Fund will employ  reasonable  procedures to confirm that
instructions  communicated by telephone are genuine; and if it does not, it may
be liable for any losses due to unauthorized or fraudulent instructions. Before
any discussion regarding your account,  the following  information is obtained:
(1)  USAA  number  and/or  account  number,  (2)  the  name(s)  on the  account
registration,  and (3)  social  security/tax  identification  number or date of
birth  of  the  registered  account  owner(s)  for  the  account  registration.
Additionally,   all  telephone   communications   with  you  are  recorded  and
confirmations of account transactions are sent to the address of record. If you
were issued stock certificates for your shares,  redemption by telephone,  fax,
telegram, or Internet is not available.

CHECKWRITING

o   Return a signed signature card,  which  accompanies  your  application,  or
    request a signature card separately and return it to:

       USAA Shareholder Account Services
       9800 Fredericksburg Road
       San Antonio, TX 78288

Your checkwriting privilege is subject to State Street Bank and Trust Company's
rules and regulations governing checking accounts.  You may write checks in the
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.
Because the value of your account  changes daily as dividends  accrue,  you may
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.

Account Balance

USAA Shareholder  Account Services (SAS), the Fund's transfer agent, may assess
annually a small balance account fee of $12 to each shareholder  account with a
balance  of less than  $2,000 at the time of  assessment.  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).

Fund Rights

The Fund reserves the right to:

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

o   limit or discontinue the offering of shares of the Fund 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 Fund's Board
    of Directors and the required notice has been given to shareholders;

o   require a  signature  guarantee  for  transactions  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 ten 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.  Exchanges  made through USAA  TouchLine(R)
and the Internet require an ESA and EFT

                                      15
<PAGE>
Buy/Sell  authorization  on file.  After we receive the  exchange  orders,  the
Fund's  transfer agent will  simultaneously  process  exchange  redemptions and
purchases  at  the  share  prices  next  determined.  The  investment  minimums
applicable to share  purchases also apply to exchanges.  For federal income tax
purposes,  an exchange  between Funds is a taxable event;  and as such, you may
realize a capital gain or loss.  Such capital  gains or losses are based on the
difference  between your cost basis in the shares and the price  received  upon
exchange.

The Fund has undertaken certain procedures regarding telephone  transactions as
described on page 14.

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

[SIDEBAR]
     NAV PER SHARE EQUALS TOTAL ASSETS MINUS LIABILITIES DIVIDED BY # OF
     SHARES OUTSTANDING

The price at which you  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.  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.

Portfolio  securities,  except  as  otherwise  noted,  traded  primarily  on  a
securities exchange are valued at the last sales price on that exchange.  If no
sale is reported, the average of the bid and asked prices is generally used.

Over-the-counter securities are generally priced at the last sales price or, if
not available, at the average of the bid and asked prices.

Debt  securities  purchased  with  maturities  of 60 days or less are stated at
amortized  cost,  which  approximates  market value.  Other debt securities are
valued each  business  day at their  current  market value as  determined  by a
pricing  service  approved by the Fund's Board of  Directors.  Securities  that
cannot be valued by these  methods,  and all other  assets,  are valued in good
faith  at fair  value  using  methods  we have  determined  under  the  general
supervision of the Fund's Board of Directors.

For  additional  information  on how  securities  are valued,  see VALUATION OF
SECURITIES in the Fund's Statement of Additional Information.

                                 16
<PAGE>
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 60 days of the July fiscal
year end, which would be somewhere  around the end of September.  The Fund will
make additional payments to shareholders, if necessary, to avoid the imposition
of any federal income or excise tax.

We  will   automatically   reinvest  all  income  dividends  and  capital  gain
distributions  in the Fund unless you instruct us differently.  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.  You  should  consider  carefully  the  effects of
purchasing shares of the Fund shortly before any  distribution.  Some or all of
these 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 Taxpayer
Relief  Act  of  1997  and  the  technical   provisions   adopted  by  the  IRS
Restructuring  and Reform Act of 1998 may  affect the status and  treatment  of
certain  distributions   shareholders  receive  from  the  Fund.  Because  each
investor's tax circumstances are unique and because the tax laws are subject to
change, we recommend that you consult your tax advisor about your investment.

SHAREHOLDER - Dividends from taxable net investment income and distributions of
net  short-term  capital gains are taxable to you 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.

                                      17
<PAGE>
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 information to you annually concerning the tax
status of dividends and distributions for federal income tax purposes.

Year 2000

Like other organizations around the world, the Fund could be adversely affected
if the computer systems used by the Fund, its service  providers,  or companies
in which the Fund invests do not  properly  process and  calculate  information
that relates to dates beginning on January 1, 2000, and beyond.  This situation
may occur because for many years computer  programmers  used only two digits to
describe  years,  such as 98 for 1998. A program written in this manner may not
work when it encounters the year 00. To confront this situation, USAA companies
have  spent  much  effort and money;  and we are  confident  that our  critical
systems  are  essentially  prepared  for the Year  2000.  In  addition,  we are
actively assessing the Year 2000 readiness of our service providers,  partners,
and companies in whose  securities we invest.  It is not possible for us to say
that you will experience no effect from this situation,  but we can say that we
are making a large effort to avoid ill effects upon our shareholders.

We do believe you are entitled to know with certainty that we will stand behind
your share balance as of the close of business in 1999. When the market reopens
in 2000,  should any computer problem cause a change in the number of shares in
your account, we will return your account to its proper share balance.

FINANCIAL HIGHLIGHTS

The financial  highlights  table is intended to help you  understand the Fund's
financial  performance for the past five years.  Certain  information  reflects
financial  results  for a single  Fund  share.  The total  returns in the table
represent  the  rate  that an  investor  would  have  earned  (or  lost)  on an
investment   in  the  Fund   (assuming   reinvestment   of  all  dividends  and

<PAGE>
                                   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 the  Fund's  assets in  securities  (including  securities  with
variable  interest rates) that 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 the Fund's assets 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   Because the interest  rates of variable rate  securities  are  periodically
    adjusted  to reflect  current  market  rates,  their  market  value is less
    affected by changes in prevailing  interest  rates than the market value of
    securities with fixed interest rates.

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 the Fund's assets 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  the  Fund's   assets  in   repurchase   agreements   that  are
collateralized  by  obligations  issued or guaranteed as to both  principal and
interest  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.

                                      20
<PAGE>
MUNICIPAL LEASE OBLIGATIONS

We may  invest  the Funds  assets in a variety of  instruments  referred  to as
municipal lease obligations, including:

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

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.

                                      21
<PAGE>
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  obligations) as well as dollar-denominated
instruments  that  have been  issued by  foreign  issuers  in the U.S.  capital
markets (Yankee obligations).

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 Fund's 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  invest  up to 15% of the  Fund's  net  assets  in  securities  that are
illiquid.  Illiquid securities are those securities which cannot be disposed of
in the ordinary course of business,  seven days or less, at  approximately  the
same value at which the Fund has valued the securities.

WHAT IS THE FUND'S INVESTMENT
OBJECTIVE AND MAIN STRATEGY?

The  Fund's  investment   objective  is  the  highest  income  consistent  with
preservation  of capital and the  maintenance of liquidity.  We will attempt to
achieve this  objective by investing  the Fund's assets in  high-quality,  U.S.
dollar-denominated,  short-term  debt  instruments  that present minimal credit
risk and comply with strict Securities and Exchange Commission (SEC) guidelines
applicable to money market funds.

In view of the risks inherent in all  investments  in  securities,  there is no
assurance that the Fund's  objective will be achieved.  See FUND INVESTMENTS on
page 6 for more information.

MAIN RISKS OF INVESTING IN THIS FUND

The primary  risks of investing in this Fund are interest  rate risk and credit
risk.

o   INTEREST  RATE RISK involves the  possibility  that the value of the Fund's
    investments will fluctuate due to changes in interest rates.

    IF INTEREST RATES INCREASE: the yield of the Fund may increase, which would
    likely increase the Fund's total return.

    IF INTEREST RATES DECREASE: the yield  of the Fund  may decrease, which may
    decrease the Fund's total return.

o   CREDIT  RISK  involves the possibility  that a borrower  cannot make timely
    interest and principal payments on its securities.

Money market funds are  sometimes  confused  with savings  accounts.  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
dollar amount,  the Federal Deposit  Insurance  Corporation  (FDIC) will insure
that the bank meets its obligations.

This Fund is not a savings account but,  rather,  is a money market mutual fund
that  issues and  redeems  its shares at the Fund's net asset  value  (NAV) per
share. The Fund always seeks to maintain a constant NAV of $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.

Unlike a savings account,  however, an investment in this Fund is not a deposit
of USAA  Federal  Savings  Bank,  or any  other  bank,  and is not  insured  or
guaranteed by the FDIC or any other government agency.

                                       2
<PAGE>

Although  the Fund seeks to  preserve  the value of your  investment  at $1 per
share, it is possible to lose money by investing in this Fund.

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.
   o You would like checkwriting privileges on the account.

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.

This  Fund by  itself  does  not  constitute  a  balanced  investment  program.
Diversifying  your investments may improve your long-run  investment return and
lower the volatility of your overall investment portfolio.

COULD THE VALUE OF YOUR INVESTMENT
IN THIS FUND FLUCTUATE?

Yes, it could.  We manage the Fund in  accordance  with  strict SEC  guidelines
designed to preserve the Fund's value at $1 per share,  although, of course, we
cannot  guarantee that the value will remain at $1 per share. The value of your
investment  typically will grow through  reinvested  dividends.  The bar chart,
shown below,  illustrates the Fund's  volatility and  performance  from year to
year over the past ten years.

Total Return

[SIDEBAR]
     TOTAL RETURN MEASURES THE PRICE CHANGE IN A SHARE ASSUMING THE
     REINVESTMENT OF ALL DIVIDEND INCOME AND CAPITAL GAIN DISTRIBUTIONS.

All mutual funds must use the same formula to calculate total return.

Yield

[SIDEBAR]
     YIELD IS THE ANNUALIZED NET INCOME OF THE FUND DURING A SPECIFIED
     PERIOD AS A PERCENTAGE OF THE FUND'S SHARE PRICE.

     EFFECTIVE YIELD IS CALCULATED SIMILAR TO THE YIELD, HOWEVER, WHEN
     ANNUALIZED, THE INCOME EARNED IS ASSUMED TO BE REINVESTED.

All mutual funds must use the same  formulas to calculate  yield and  effective
yield. The Fund typically advertises  performance in terms of a 7-day yield and
effective yield and may advertise total return.  The 7-day yield quotation more
closely reflects current earnings of the Fund than the total return  quotation.
The  effective  yield will be  slightly  higher  than the yield  because of the
compounding  effect of the assumed  reinvestment.  Current yields 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.
The Fund's 7-day yield for the period ended December 31, 1998, was 5.00%.

Please  consider  performance  information  in light of the  Fund's  investment
objective and policies and market  conditions during the reported time periods.
The value of your shares may go up or down. For the most current price,  yield,

FUND INVESTMENTS

Principal Investment Strategies and Risks

  Q  What is the Fund's principal investment strategy?

  A  The  Fund's  principal  strategy  is  the  investment  of  its  assets  in
     high-quality,  U.S.  dollar-denominated  debt  securities  of domestic and
     foreign issuers that have been determined to present minimal credit risk.

  Q  What types of money market instruments  will the Fund's assets be invested
     in?

  A  The Fund's portfolio may include the following:

     o obligations of the U.S. government, its  agencies 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;

                                       6
<PAGE>
     o asset-backed securities;
     o master demand notes;
     o Eurodollar obligations;
     o Yankee obligations; and
     o other short-term debt securities.

     For a further description of these securities, see APPENDIX A on page 20.

  Q  Are there any limits on how much can be invested 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.  Also,  strict SEC  guidelines  do not  permit us to invest,  with
     respect to 75% of the Fund's assets, greater than 10% of the Fund's assets
     in securities  issued by or subject to guarantees by the same institution.
     Purchases of securities issued or guaranteed by the U.S. government or its
     agencies or instrumentalities are not counted toward these limitations.

  Q  What is the credit quality of the Fund's investments?

  A  The Fund's  investments  consist  of 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  or  subject  to  a  guarantee  that  is  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 or guaranteed by a guarantor that has
         other comparable short-term obligations so rated; or
     o   unrated but determined by us to be of comparable quality.

     In addition,  we must consider  whether a particular  investment  presents
     minimal credit risk.

                                       7
<PAGE>
  Q  Who are the Nationally Recognized Statistical Rating Organizations?

  A  Current NRSROs include:

     o Moody's Investors Service;
     o Standard & Poor's Ratings Group;
     o Fitch IBCA;
     o Duff & Phelps Credit Rating Co.; and
     o Thompson BankWatch.

  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?

[SIDEBAR]
     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 THE TOTAL
     BY THE DOLLAR VALUE OF THE FUND'S PORTFOLIO.

  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  category  for  short-term  securities,   or,  if  not  rated,  of
     comparable  quality,  at the time of purchase.  Additionally,  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
     rate risk by limiting  the  maturity of each  security to 397 days or less
     and maintaining a dollar-weighted  average portfolio maturity for the Fund
     of 90 days or less.

  Q  How are the decisions to buy or sell securities made?

  A  We balance  factors such as credit  quality  and  maturity to purchase the
     best relative value available in the market at any given time. While rare,
     sell decisions are usually based on a change in our credit  analysis or to
     take advantage of an opportunity to reinvest at a higher yield.

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 you of the need to make  individual
stock or bond selections. You also

                                       9
<PAGE>
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 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 to fit your
own risk and reward goals.

III. USAA's Family of Funds

We offer you  another  alternative  with our  asset  strategy  funds  listed in
APPENDIX B under asset allocation on page 23. These unique mutual funds provide
a  professionally  managed,  diversified  investment  portfolio within a mutual
fund.  Designed for the individual who prefers to delegate the asset allocation
process to an investment  manager,  their  structure  achieves  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 member service
representatives  stand  ready to assist you with your  choices  and to help you
craft a  portfolio  to meet your  needs.  Refer to  APPENDIX B on page 23 for a
complete list of the USAA Family of No-Load Mutual Funds.

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),  phone, or Internet. A
complete, signed application is required to open your initial account. However,
after  you open your  initial  account  with us,  you will not need to fill out
another  application  to invest in  another  Fund  unless the  registration  is
different.

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.  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  and  payment  prior to that time,  your
purchase price will be the NAV per share determined for that day. If we receive
your  request or payment  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.
This will avoid a potential  four- to six-week  delay in the effective  date of
your  purchase.  Furthermore,  a bank charge may be  assessed  in the  clearing
process, which will be deducted from the amount of the purchase.

MINIMUM INVESTMENTS

     account through payroll deduction for as little as $25 per pay period with

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), your redemption will be effective on the next business day.

We will send you your  money  within  seven days  after the  effective  date of
redemption.  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.  For federal
income tax purposes,  a redemption  is a taxable  event;  and as such,  you may
realize a capital gain or loss.  Such capital  gains or losses are based on the
difference  between your cost basis in the shares and the price  received  upon
redemption.


                                      13

IMPORTANT INFORMATION ABOUT
PURCHASES AND REDEMPTIONS

Investor's Guide to USAA Mutual Fund Services
[INVESTOR'S GUIDE GRAPHIC]

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 assist 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

USAA Shareholder  Account Services (SAS), the Fund's transfer agent, may assess
annually a small balance account fee of $12 to each shareholder  account with a
balance  of less than  $2,000 at the time of  assessment.  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).

Fund Rights

The Fund reserves the right to:

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

o   limit or  discontinue the offering of  shares of the Fund 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 Fund's Board
    of Directors and the required notice has been given to shareholders;

o   require a  signature  guarantee  for  transactions  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.

                                      15

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.  Exchanges  made through USAA  TouchLine(R)
and the Internet  require an ESA and EFT Buy/Sell  authorization on file. After
we receive the exchange orders,  the Fund's transfer agent will  simultaneously
process exchange redemptions and purchases at the share prices next determined.
The investment  minimums applicable to share purchases also apply to exchanges.
For federal income tax purposes,  an exchange between Funds is a taxable event;
and as such,  you may realize a capital  gain or loss.  Such  capital  gains or
losses are based on the  difference  between  your cost basis in the shares and
the price received upon exchange.

The Fund has undertaken certain procedures regarding telephone  transactions as
described on page 14.


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

[SIDEBAR]
     NAV PER SHARE EQUALS TOTAL ASSETS MINUS LIABILITIES DIVIDED BY # OF SHARES
     OUTSTANDING

The price at which you  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.  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.
Securities are stated at amortized cost, which approximates market value.

For  additional  information  on how  securities  are valued,  see VALUATION OF
SECURITIES in the Fund's Statement of Additional Information.

                                      16
<PAGE>
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.

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 Taxpayer
Relief  Act  of  1997  and  the  technical   provisions   adopted  by  the  IRS
Restructuring  and Reform Act of 1998 may  affect the status and  treatment  of
certain  distributions   shareholders  receive  from  the  Fund.  Because  each
investor's tax circumstances are unique and because the tax laws are subject to
change, we recommend that you consult your tax advisor about your investment.

SHAREHOLDER - Dividends from taxable net investment income and distributions of
net  short-term  capital gains are taxable to you 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.


                                      17
<PAGE>
REPORTING - The Fund will report information to you annually concerning the tax
status of dividends and distributions for federal income tax purposes.

Year 2000

Like other organizations around the world, the Fund could be adversely affected
if the computer systems used by the Fund, its service  providers,  or companies
in which the Fund invests do not  properly  process and  calculate  information
that relates to dates beginning on January 1, 2000, and beyond.  This situation
may occur because for many years computer  programmers  used only two digits to
describe  years,  such as 98 for 1998. A program written in this manner may not
work when it encounters the year 00. To confront this situation, USAA companies
have  spent  much  effort and money;  and we are  confident  that our  critical
systems  are  essentially  prepared  for the Year  2000.  In  addition,  we are
actively assessing the Year 2000 readiness of our service providers,  partners,
and companies in whose  securities we invest.  It is not possible for us to say
that you will experience no effect from this situation,  but we can say that we
are making a large effort to avoid ill effects upon our shareholders.

We do believe you are entitled to know with certainty that we will stand behind
your share balance as of the close of business in 1999. When the market reopens
in 2000,  should any computer problem cause a change in the number of shares in
your account, we will return your account to its proper share balance.

FINANCIAL HIGHLIGHTS

The financial  highlights  table is intended to help you  understand the Fund's
financial  performance for the past five years.  Certain  information  reflects
financial  results  for a single  Fund  share.  The total  returns in the table
represent  the  rate  that an  investor  would  have  earned  (or  lost)  on an
investment  in  this  Fund   (assuming   reinvestment   of  all  dividends  and
distributions).  This  information  has been audited by KPMG LLP, whose report,
along with the Fund's financial statements,  are included in the Annual Report,

                                   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 the  Fund's  assets in  securities  (including  securities  with
variable  interest rates) that 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 the Fund's assets 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   Because the interest  rates of variable rate  securities  are  periodically
    adjusted  to reflect  current  market  rates,  their  market  value is less
    affected by the  changes in  prevailing  interest  rates than the market of
    securities with fixed interest rates.

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 the Fund's assets 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  the  Fund's   assets  in   repurchase   agreements   that  are
collateralized  by  obligations  issued or guaranteed as to both  principal and
interest  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.

                                      20
<PAGE>
MUNICIPAL LEASE OBLIGATIONS

We may invest the Fund's assets 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.

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  obligations) as well as dollar-denominated
instruments  that  have been  issued by  foreign  issuers  in the U.S.  capital
markets (Yankee obligations).

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.

                                      21
<PAGE>
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 Fund's 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  invest  up to 10% of the  Fund's  net  assets  in  securities  that are
illiquid.  Illiquid securities are those securities which cannot be disposed of
in the ordinary course of business,  seven days or less, at  approximately  the
same value at which the Fund has valued the securities.

the Prospectus.

WHAT IS THE FUND'S INVESTMENT
OBJECTIVE AND MAIN STRATEGY?

The Fund's  investment  objective is long-term  capital  appreciation.  We will
attempt to achieve  this  objective by  investing  the Fund's  assets in equity
securities  of companies  expected to benefit from the  development  and use of
scientific and technological advances and improvements.

In view of the risks inherent in all  investments  in  securities,  there is no
assurance that the Fund's  objective will be achieved.  See FUND INVESTMENTS on
page 6 for more information.

MAIN RISKS OF INVESTING IN THIS FUND

The primary risks of investing in this Fund are market risk and industry risk.


o   MARKET  RISK  involves  the  possibility  that  the  value of  the  Fund's
    investments  in equity  securities  will  decline in  a down stock  market,
    regardless of the success or failure of any  one company's operations.

o   INDUSTRY  RISK  involves the  possibility  that the Fund's  investments  in
    companies whose value is highly  dependent on scientific and  technological
    developments  may be more  volatile  because of the short  life  cycles and
    competitive  pressures  of  many  of the  products  or  services  of  these
    companies.

Another  risk of the  Fund  described  later in the  Prospectus  is the risk of
foreign investing.  As with other mutual funds,  losing money is also a risk of
investing in this Fund.

As you consider an investment  in this 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 the  investment  for long periods of time
to ride out down periods.

                                       2
<PAGE>
An  investment  in this Fund is not a deposit of USAA Federal  Savings Bank, or
any other  bank,  and is not  insured  or  guaranteed  by the  Federal  Deposit
Insurance Corporation or any other government agency.

[CAUTION LIGHT]

Look for this symbol throughout the Prospectus. We use it to mark more detailed
information about the risks you will face as a Fund shareholder.

IS THIS FUND FOR YOU?

This Fund might be appropriate as part of your investment portfolio if . . .

   o You are looking for significant growth.
   o You are willing to accept very high risk.
   o You are looking for a long-term investment.

This Fund MAY NOT be appropriate as part of your investment portfolio if . . .

   o You need steady income.
   o You are unwilling to take greater risk for long-term goals.

   o You need an investment that provides tax-free income.

This  Fund by  itself  does  not  constitute  a  balanced  investment  program.
Diversifying  your investments may improve your long-run  investment return and
lower the volatility of your overall investment portfolio.

COULD THE VALUE OF YOUR INVESTMENT
IN THIS FUND FLUCTUATE?

Yes,  it  could.  In fact,  the  value of your  investment  in this  Fund  will
fluctuate with the changing  market values of the  investments in the Fund. The
Fund's  portfolio  consists of  companies  whose value is highly  dependent  on
scientific and technological developments. Many of the products and services of
these  companies  are subject to short life cycles and  competitive  pressures.
Therefore,  the market value of the Fund's  portfolio  and the Fund's price per
share are likely to fluctuate  significantly.

The bar chart, on the next page, shows the Fund's  performance for the one full
calendar  year  since  inception  and  gives  some  indication  of the risks of
investing in this Fund.

FUND INVESTMENTS

Principal Investment Strategies and Risks

  Q  What is the Fund's principal investment strategy?

  A  The Fund's  principal  strategy is the investment of at least 80% of its
     assets in equity  securities of companies that we expect will benefit from
     the  development  and use of  scientific  and  technological  advances and
     improvements.  We use the  term  "equity  securities"  to  include  common
     stocks,  preferred stocks,  securities convertible into common stocks, and
     securities that carry the right to buy common stocks.

     As a temporary defensive measure because of market,  economic,  political,
     or other  conditions,  we may  invest up to 100% of the  Fund's  assets in
     investment-grade, short-term debt instruments. This may result in the Fund
     not  achieving  its  investment  objective  during  the time it is in this
     temporary defensive posture.

     We generally will not trade the Fund's securities for short-term  profits;
     however, if circumstances  warrant, we may need to actively and frequently
     trade Fund securities to achieve the Fund's principal investment strategy.
     The Fund's  portfolio  turnover rate will vary from year to year depending
     on market conditions. A high turnover rate increases transaction costs and
     may increase taxable capital gains; therefore, we will carefully weigh the
     anticipated benefits of trading.

[CAUTION LIGHT]
MARKET RISK. Because this Fund invests in equity  securities,  it is subject to
stock  market  risk.  Stock  prices in general may  decline  over short or even
extended  periods,  regardless  of  the  success  or  failure  of  a  company's
operations. Stock markets tend to run in cycles, with periods when stock prices
generally  go up,  known as "bull"  markets,  and  periods  when  stock  prices
generally go down, referred to as "bear" markets.  Equity securities tend to go
up and down more than bonds.

  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 the Fund's  assets in foreign  securities
     purchased in either foreign or U.S. markets when they are in line with the
     Fund's investment objective.

                                       6
<PAGE>
[CAUTION LIGHT]

FOREIGN  INVESTING RISK.  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;   political
instability; difficulties in obtaining legal judgments; and foreign withholding
taxes.  In the past,  equity and debt  instruments of foreign markets have been
more volatile than equity and debt instruments of U.S. securities markets.

  Q  In what industries will the Fund's assets be invested?

  A  We will invest at least 80%  of the  Fund's net assets in industries  such
     as, but not limited to,  biotechnology,  computer  hardware,  software and
     services,  communication  and  telecommunication  equipment  and services,
     electronics,   health  care,   drugs,   medical   products  and  supplies,
     specialized  health  care  services,  aerospace  and  defense,  and  other
     industries we believe may benefit directly or indirectly from research and
     development in the science and technology fields. We may invest the Fund's
     remaining assets in any other industry.

[CAUTION LIGHT]
INDUSTRY RISK. A mutual fund portfolio consisting of investments related to the
fields of science and technology is likely to be more volatile than a portfolio
that is more  widely  diversified  in other  economic  sectors.  Because of the
competitiveness and rapid changes in the fields of science and technology, many
of the companies in the Fund's portfolio are subject to distinctive  risks. The
products and services of these companies may not be economically  successful or
may quickly become outdated.  Additionally, many of these companies must comply
with significant governmental regulations and may need governmental approval of
their products and services.

  Q  How are the decisions to buy or sell securities made?

  A  We generally  invest in companies  producing  sales  and  earnings  growth
     rates greater than those of the overall market.  Investment considerations
     include a company's ability to exceed earnings  expectations over the near
     or long term,  valuation,  cash flow,  acquisitions,  and other  corporate
     actions. We employ a bottoms-up,  stock-picking strategy focusing on these
     factors.  We monitor our positions  continually and will sell a stock when
     we perceive our original investment thesis to no longer hold.

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 Science & Technology  Fund
with investments in other mutual funds that invest in value-oriented stocks and
high-dividend  stocks. This is just one way you could combine funds to fit your
own risk and reward goals.

III. USAA's Family of Funds

We offer you  another  alternative  with our  asset  strategy  funds  listed in
APPENDIX B under asset allocation on page 21. These unique mutual funds provide
a  professionally  managed,  diversified  investment  portfolio within a mutual
fund.  Designed for the individual who prefers to delegate the asset allocation
process to an investment  manager,  their  structure  achieves  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 member service
representatives  stand  ready to assist you with your  choices  and to help you
craft a  portfolio  to meet your  needs.  Refer to  APPENDIX B on page 21 for a
complete list of the USAA Family of No-Load Mutual Funds.

HOW TO INVEST

Purchase of Share

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),  phone,  or Internet.  A
complete, signed application is required to open your initial account. However,
after  you open your  initial  account  with us,  you will not need to fill out
another  application  to invest in  another  Fund  unless the  registration  is
different.

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.  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  and  payment  prior to that time,  your
purchase price will be the NAV per share determined for that day. If we receive
your  request or payment  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.
This will avoid a potential  four- to six-week  delay in the effective  date of
your  purchase.  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

Time), your redemption will be effective on the next business day.

We will send you your  money  within  seven days  after the  effective  date of
redemption.  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.  For federal
income tax purposes,  a redemption  is a taxable  event;  and as such,  you may
realize a capital gain or loss.  Such capital gains or losses are based on your
cost basis in the shares and the price received upon redemption.

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 assist you in
your role as an investor.  In the INVESTOR'S  GUIDE,  you will find  additional

Account Balance

USAA Shareholder  Account Services (SAS), the Fund's transfer agent, may assess
annually a small balance account fee of $12 to each shareholder  account with a
balance  of less than  $2,000 at the time of  assessment.  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).

Fund Rights

The Fund reserves the right to:

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

o   limit or discontinue the offering  of shares of the  Fund 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 Fund's Board
    of Directors and the required notice has been given to shareholders;

o   require a  signature  guarantee  for  transactions  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 ten 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.  Exchanges  made through USAA  TouchLine(R)
and the Internet  require an ESA and EFT Buy/Sell  authorization on file. After
we receive the exchange orders,  the Fund's transfer agent will  simultaneously
process exchange redemptions

                                      14
<PAGE>
and  purchases at the share prices next  determined.  The  investment  minimums
applicable to share  purchases also apply to exchanges.  For federal income tax
purposes,  an exchange  between Funds is a taxable event;  and as such, you may
realize a capital gain or loss.  Such capital  gains or losses are based on the
difference  between your cost basis in the shares and the price  received  upon
exchange.

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

[SIDEBAR]
     NAV PER SHARE EQUALS TOTAL ASSETS MINUS LIABILITIES DIVIDED BY # OF SHARES
     OUTSTANDING

The price at which you  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.  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.

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
valued at the last quoted sales price, or the most recently  determined closing
price calculated  according to local market  convention,  available at the time
the Fund is valued.  If no sale is reported,  the average of  the bid and asked
prices is generally used.

Securities  trading in various  foreign markets may take place on days when the
NYSE is closed.  Further,  when the NYSE is open,  the  foreign  markets may be
closed.  Therefore, the calculation of the Fund's NAV may not take place at the
same time the prices of certain securities held by the Fund are determined.  In
most cases,  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 the Fund's NAV is  calculated  will not be  reflected  in the
Fund's NAV. If, however,  we determine that a particular event would materially
affect the Fund's NAV, then we, under the general

                                      15
<PAGE>

supervision of the Fund's Board of Directors, will use all relevant,  available
information to determine a fair value for the affected portfolio securities.

Over-the-counter securities are generally priced at the last sales price or, if
not available, at the average of the bid and asked prices.

Debt  securities  purchased  with  maturities  of 60 days or less are stated at
amortized  cost,  which  approximates  market value.  Other debt securities are
valued each  business  day at their  current  market value as  determined  by a
pricing  service  approved by the Fund's Board of  Directors.  Securities  that
cannot be valued by these  methods,  and all other  assets,  are valued in good
faith  at fair  value  using  methods  we have  determined  under  the  general
supervision of the Fund's Board of Directors.

For  additional  information  on how  securities  are valued,  see VALUATION OF
SECURITIES in the Fund's Statement of Additional Information.

Dividends and Distributions

The Fund pays net  investment  income  dividends  yearly.  Any net capital gain
distribution  usually  occurs  within 60 days of the July 31  fiscal  year end,
which  would be  somewhere  around  the end of  September.  The Fund  will make
additional payments to shareholders,  if necessary,  to avoid the imposition of
any federal income or excise tax.

We  will   automatically   reinvest  all  income  dividends  and  capital  gain
distributions  in the Fund unless you instruct us differently.  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  on the  ex-dividend
date.  You should  consider  carefully the effects of purchasing  shares of the
Fund  shortly  before  any  dividend  or  distribution.  Some  or all of  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 Taxpayer
Relief  Act  of  1997  and  the  technical   provisions   adopted  by  the  IRS
Restructuring  and Reform Act of 1998 may  affect the status and  treatment  of
certain distributions shareholders receive from the Fund.

                                      16
<PAGE>
Because each investor's tax  circumstances  are unique and because the tax laws
are subject to change,  we recommend  that you consult  your tax adviser  about
your investment.

SHAREHOLDER - Dividends from taxable net investment income and distributions of
net  short-term  capital gains are taxable to you 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.

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 information to you annually concerning the tax
status of dividends and distributions for federal income tax purposes.

                                      17

Year 2000

Like other organizations around the world, the Fund could be adversely affected
if the computer systems used by the Fund, its service  providers,  or companies
in which the Fund invests do not  properly  process and  calculate  information
that relates to dates beginning on January 1, 2000, and beyond.  This situation
may occur because for many years computer  programmers  used only two digits to
describe  years,  such as 98 for 1998. A program written in this manner may not
work when it encounters the year 00. To confront this situation, USAA companies
have  spent  much  effort and money;  and we are  confident  that our  critical
systems  are  essentially  prepared  for the Year  2000.  In  addition,  we are
actively assessing the Year 2000 readiness of our service providers,  partners,
and companies in whose  securities we invest.  It is not possible for us to say
that you will experience no effect from this situation,  but we can say that we
are making a large  effort to avoid ill effects upon our  shareholders.

We do believe you are entitled to know with certainty that we will stand behind
your share balance as of the close of business in 1999. When the market reopens
in 2000,  should any computer problem cause a change in the number of shares in
your account, we will return your account to its proper share balance.

                                   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 the Fund's  assets in  convertible  securities,  which are bonds,
preferred stocks, and other securities that pay interest or dividends and offer
the buyer the ability to convert 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.

MONEY MARKET INSTRUMENTS

We may hold a certain  portion of the Fund's assets in  investment-grade,  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,
banker's  acceptances,  and  other  financial  institution  obligations.  These
securities may carry fixed or variable interest rates.

ILLIQUID SECURITIES

We may  invest  up to 15% of the  Fund's  net  assets  in  securities  that are
illiquid.  Illiquid securities are those securities which cannot be disposed of
in the ordinary course of business,  seven days or less, at  approximately  the
same value at which the Fund has valued the securities.

FORWARD CURRENCY CONTRACTS

We may hold  securities  denominated in foreign  currencies.  As a result,  the
value of these  securities  will be  affected by changes in the  exchange  rate
between the dollar and the foreign  currencies.  In managing currency exposure,
the Fund may enter into forward currency contracts. A forward currency contract
is 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 may only  enter into  forward  currency  contracts  when the Fund
enters into a contract for the purchase or sale of a security  denominated in a
foreign currency and desires to "lock in" the U.S. dollar price of the security
until settlement.

AMERICAN DEPOSITARY RECEIPTS (ADRS)

We may invest the Fund's  assets in ADRs,  which are  foreign  shares held by a
U.S.  bank that issues a receipt  evidencing  ownership.  Dividends are paid in
U.S. dollars.

GLOBAL DEPOSITARY RECEIPTS (GDRS)

We may invest the Fund's  assets in GDRs,  which are  foreign  shares held by a
U.S. or foreign bank that issues a receipt evidencing ownership.  Dividends are
paid in U.S. dollars.

The USAA First Start Growth Fund is designed to stimulate interest in long-term
investing by young people.  It is part of USAA First Start, a money  management
plan for young people.

As with other mutual funds,  the  Securities  and Exchange  Commission  has not
approved  or  disapproved  of this Fund's  shares or  determined  whether  this
prospectus  is  accurate  or  complete.  Anyone  who  tells  you  otherwise  is

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

WHAT IS THE FUND'S INVESTMENT OBJECTIVE AND MAIN STRATEGY?

The Fund's  investment  objective is long-term  capital  appreciation.  We will
attempt to achieve  this  objective by  investing  the Fund's  assets in equity
securities of companies  that provide goods or services we believe are familiar
to young people.

In view of the risks inherent in all  investments  in  securities,  there is no
assurance that the Fund's  objective will be achieved.  See FUND INVESTMENTS on
page 6 for more information.

MAIN RISKS OF INVESTING IN THIS FUND

The primary risk of investing in this Fund is market risk.

o   MARKET  RISK  involves  the  possibility  that  the  value  of  the  Fund's
    investments  in equity  securities  will  decline in a down  stock  market,
    regardless of the success or failure of any one company's operations.

Another  risk of the  Fund  described  later in the  Prospectus  is the risk of
foreign investing.  As with other mutual funds,  losing money is also a risk of
investing in this Fund.

As you consider an investment  in this 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 the  investment  for long periods of time
to ride out down periods.

An  investment  in this Fund is not a deposit of USAA Federal  Savings Bank, or
any other  bank,  and is not  insured  or  guaranteed  by the  Federal  Deposit
Insurance Corporation or any other government agency.

[CAUTION LIGHT]

Look for this symbol throughout the Prospectus. We use it to mark more detailed
information about the risks you will face as a Fund shareholder.

IS THIS FUND FOR YOU?

This Fund might be appropriate as part of your investment portfolio if . . .

   o  You are interested in learning about investments.
   o  You are willing to accept moderate to high risk.
   o  You are looking for a long-term investment.

                                       2
<PAGE>
This Fund MAY NOT be appropriate as part of your investment portfolio if . . .

   o  You need steady income.

   o  You are unwilling to take greater risk for long-term goals.
   o  You need an investment that provides tax-free income.

This  Fund by  itself  does  not  constitute  a  balanced  investment  program.
Diversifying  your investments may improve your long-run  investment return and
lower the volatility of your overall investment portfolio.

COULD THE VALUE OF YOUR INVESTMENT
IN THIS FUND FLUCTUATE?

Yes,  it  could.  In fact,  the  value of your  investment  in this  Fund  will
fluctuate with the changing  market values of the  investments in the Fund. The
bar chart,  shown below,  illustrates  the Fund's  performance for the one full
calendar  year  since  inception  and  gives  some  indication  of the risks of
investing in this Fund.

Total Return

[SIDEBAR]
     TOTAL RETURN MEASURES THE PRICE CHANGE IN A SHARE ASSUMING THE
     REINVESTMENT OF ALL DIVIDEND INCOME AND CAPITAL GAIN DISTRIBUTIONS.

All mutual funds must use the same formula to calculate total return.

                   *FUND BEGAN OPERATIONS ON AUGUST 1, 1997.

          THE FUND'S TOTAL RETURN FOR THE NINE-MONTH PERIOD ENDED

FUND INVESTMENTS

Principal Investment Strategies and Risks

  Q  What is the Fund's principal investment strategy?

  A  The Fund's principal  strategy  is the investment  of its assets in equity
     securities  of  companies  providing  goods or  services  we  believe  are
     familiar to young people.  We use the term "equity  securities" to include
     common stocks,  securities  convertible into common stocks, and securities
     that carry the right to buy common stocks.

     We  designed  the  Fund as part of a  program  to  stimulate  interest  in
     long-term investing by young people.  Shareholders of the Fund may give us
     their  suggestions  about the types of  companies  they  would  like us to
     consider for investment by the Fund. We invite shareholders to tell us the
     investment  topics or the names of stocks they would like us to feature in
     the Fund's communications to shareholders.

     As a temporary defensive measure because of market,  economic,  political,
     or other  conditions,  we may  invest up to 100% of the  Fund's  assets in
     investment-grade, short-term debt instruments. This may result in the Fund
     not  achieving  its  investment  objective  during  the time it is in this
     temporary defensive posture.

[CAUTION LIGHT]
MARKET RISK. Because this Fund invests in equity  securities,  it is subject to
stock  market  risk.  Stock  prices in general may  decline  over short or even
extended  periods,  regardless  of  the  success  or  failure  of  a  company's
operations. Stock markets tend to run in cycles, with periods when stock prices
generally  go up,  known as "bull"  markets,  and  periods  when  stock  prices
generally go down, referred to as "bear" markets.  Equity securities tend to go
up and down more than bonds.

  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 the Fund's  assets in foreign  securities
     purchased on either foreign or U.S. markets when they are in line with the
     Fund's investment objective.

                                       6
<PAGE>
[CAUTION LIGHT]

FOREIGN  INVESTING RISKS.  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;   political
instability;   difficulties   in  obtaining  legal   judgements;   and  foreign
withholding  taxes. In the past, equity and debt instruments of foreign markets
have been more volatile  than equity and debt  instruments  of U.S.  securities
markets.

  Q  In what industries will the Fund's assets be invested?

  A  We will invest  in many  different industries.  The Fund is not a "sector"
     fund that focuses its investments in a specific  industry or sector of the
     economy. We believe that goods or services which are likely to be familiar
     to young  investors  are provided by companies  engaged in many  different
     types of  industries.  Such  companies may include  computer  hardware and
     software manufacturers,  Internet service providers,  and companies in the
     apparel, automobile,  communications,  entertainment,  financial services,
     health services, and travel industries,  among others. We believe that the
     flexibility  to  select  equity  securities  of  companies  across a broad
     universe  of  industries  maximizes  our  opportunity  to find  attractive
     investments  as we  pursue  the  Fund's  objective  of  long-term  capital
     appreciation.

  Q  Are the Fund's  assets  prohibited  from  being invested in any specific
     industries?

  A  Yes. We will  not invest in  companies  whose  primary line of business is
     the production of  tobacco products or  alcoholic  beverages.  Investments
     in firms primarily focused on gaming activities are also prohibited.

  Q  What special services are provided to shareholders in this Fund?

  A  In addition to providing an investment  opportunity for  long-term capital
     appreciation, shareholders  will receive  educational information targeted
     to young people about the basic concepts of saving and investing.

                                       7
<PAGE>
  Q  How are the decisions to buy and sell securities made?

  A  We buy stocks of companies that provide  goods or  services we believe are
     familiar to young people. We generally invest in companies producing sales
     and  earnings  growth  rates  greater  than those of the  overall  market.
     Investment  considerations  include a company's ability to exceed earnings
     expectations   over  the  near  or  long  term,   valuation,   cash  flow,
     acquisitions,  and  other  corporate  actions.  We  employ  a  bottoms-up,
     stock-picking strategy focusing on these factors. We monitor our positions
     continually and will sell a stock when we perceive our original investment
     thesis to no longer hold.

For additional  information  about other  securities in which we may invest the
Fund's assets, see APPENDIX A on page 20.

FUND MANAGEMENT

USAA  Investment  Management  Company serves as the manager and  distributor of
this  Fund.  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  $40   billion in total  assets  under
management.  Our mailing address is 9800  Fredericksburg  Road, San Antonio, TX
78288.

We provide management  services to the Fund pursuant to an Advisory  Agreement.
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 Fund's Board of Directors.  For our services,  the Fund pays
us an annual fee. The fee is computed at three-fourths of one percent (.75%) of
average  net  assets.  The fee we  received  for the fiscal year ended July 31,
1999,  after we made  reimbursements  to the Fund, was equal to .53% of average
net assets.  We also provide  services related to selling the Fund's shares and
receive no compensation for those services.

Portfolio Transactions

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

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.

                                       9
<PAGE>

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

III. USAA's Family of Funds

We offer you  another  alternative  with our  asset  strategy  funds  listed in
APPENDIX B under asset allocation on page 21. These unique mutual funds provide
a  professionally  managed,  diversified  investment  portfolio within a mutual
fund.  Designed for the individual who prefers to delegate the asset allocation
process to an investment  manager,  their  structure  achieves  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 member service
representatives  stand  ready to assist you with your  choices  and to help you
craft a  portfolio  to meet your  needs.  Refer to  APPENDIX B on page 21 for a
complete list of the USAA Family of No-Load Mutual Funds.

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),  phone,  or Internet.  A
complete, signed application is required to open your initial account. However,
after  you open your  initial  account  with us,  you will not need to fill out
another  application  to invest in  another  Fund  unless the  registration  is
different.

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.  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

                                      10
<PAGE>
and payment prior to that time,  your purchase  price will be the NAV per share
determined  for that day. If we receive your  request or payment  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.
This will avoid a potential  four- to six-week  delay in the effective  date of
your  purchase.  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
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), your redemption will be effective on the next business day.

We will send you your  money  within  seven days  after the  effective  date of
redemption.  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.  For federal
income tax purposes,  a redemption  is a taxable  event;  and as such,  you may
realize a capital gain or loss.  Such capital  gains or losses are based on the
difference  between your cost basis in the shares and the price  received  upon
redemption.

In addition, the Fund 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
[INVESTOR'S GUIDE GRAPHIC]

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 assist 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

USAA Shareholder  Account Services (SAS), the Fund's transfer agent, may assess
annually a small balance account fee of $12 to each shareholder  account with a
balance  of less than  $2,000 at the time of  assessment.  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).

Fund Rights

The Fund reserves the right to:

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

o   limit or discontinue  the offering of shares  of the Fund 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 Fund's Board
    of Directors and the required notice has been given to shareholders;

                                      14
<PAGE>
o   require a  signature  guarantee  for  transactions  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 ten 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.  Exchanges  made through USAA  TouchLine(R)
and the Internet  require an ESA and EFT Buy/Sell  authorization on file. After
we receive the exchange orders,  the Fund's transfer agent will  simultaneously
process exchange redemptions and purchases at the share prices next determined.
The investment  minimums applicable to share purchases also apply to exchanges.
For federal income tax purposes,  an exchange between Funds is a taxable event;
and as such,  you may realize a capital  gain or loss.  Such  capital  gains or
losses are based on the  difference  between  your cost basis in the shares and
the price received upon exchange.

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

[SIDEBAR]
     NAV PER SHARE EQUALS TOTAL ASSETS MINUS LIABILITIES DIVIDED BY # OF SHARES
     OUTSTANDING

The price at which you  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.  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.

                                      15
<PAGE>

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
valued at the last quoted sales price, or the most recently  determined closing
price calculated  according to local market  convention,  available at the time
the Fund is valued.  If no sale is  reported,  the average of the bid and asked
prices is generally used.

Securities  trading in various  foreign markets may take place on days when the
NYSE is closed.  Further,  when the NYSE is open,  the  foreign  markets may be
closed.  Therefore, the calculation of the Fund's NAV may not take place at the
same time the prices of certain securities held by the Fund are determined.  In
most cases,  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 the Fund's NAV is  calculated  will not be  reflected  in the
Fund's NAV. If, however,  we determine that a particular event would materially
affect the Fund's NAV,  then we,  under the general  supervision  of the Fund's
Board of Directors, will use all relevant, available information to determine a
fair value for the affected portfolio securities.

Over-the-counter securities are generally priced at the last sales price or, if
not available, at the average of the bid and asked prices.

Debt  securities  purchased  with  maturities  of 60 days or less are stated at
amortized  cost,  which  approximates  market value.  Other debt securities are
valued each  business  day at their  current  market value as  determined  by a
pricing  service  approved by the Fund's Board of  Directors.  Securities  that
cannot be valued by these  methods,  and all other  assets,  are valued in good
faith  at fair  value  using  methods  we have  determined  under  the  general
supervision of the Fund's Board of Directors.

For  additional  information  on how  securities  are valued,  see VALUATION OF
SECURITIES in the Fund's Statement of Additional Information.

Dividends and Distributions

The Fund pays net  investment  income  dividends  yearly.  Any net capital gain
distribution  usually  occurs  within 60 days of the July 31  fiscal  year end,
which  would be  somewhere  around  the end of  September.  The Fund  will make
additional payments to shareholders,  if necessary,  to avoid the imposition of
any federal income or excise tax.

We  will   automatically   reinvest  all  income  dividends  and  capital  gain
distributions  in the Fund unless you instruct us differently.  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.

                                      16
<PAGE>
You should  consider  carefully  the effects of  purchasing  shares of the Fund
shortly before any dividend or distribution. Some or all of 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 Taxpayer
Relief  Act  of  1997  and  the  technical   provisions   adopted  by  the  IRS
Restructuring  and Reform Act of 1998 may  affect the status and  treatment  of
certain  distributions   shareholders  receive  from  the  Fund.  Because  each
investor's tax circumstances are unique and because the tax laws are subject to
change, we recommend that you consult your tax adviser about your investment.

SHAREHOLDER - Dividends from taxable net investment income and distributions of
net  short-term  capital gains are taxable to you 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.

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 information to you annually concerning the tax
status of dividends and distributions for federal income tax purposes.

                                      17

Year 2000

Like other organizations around the world, the Fund could be adversely affected
if the computer systems used by the Fund, its service  providers,  or companies
in which the Fund invests do not  properly  process and  calculate  information
that relates to dates beginning on January 1, 2000, and beyond.  This situation
may occur because for many years computer  programmers  used only two digits to
describe  years,  such as 98 for 1998. A program written in this manner may not
work when it encounters the year 00. To confront this situation, USAA companies
have  spent  much  effort and money;  and we are  confident  that our  critical
systems  are  essentially  prepared  for the Year  2000.  In  addition,  we are
actively assessing the Year 2000 readiness of our service providers,  partners,
and companies in whose  securities we invest.  It is not possible for us to say
that you will experience no effect from this situation,  but we can say that we
are making a large effort to avoid ill effects upon our shareholders.

We do believe you are entitled to know with certainty that we will stand behind
your share balance as of the close of business in 1999. When the market reopens
in 2000,  should any computer problem cause a change in the number of shares in
your account, we will return your account to its proper share balance.

FINANCIAL HIGHLIGHTS

The financial  highlights  table is intended to help you  understand the Fund's
financial  performance since inception.  Certain information reflects financial
results for a single Fund share.  The total returns in the table  represent the
rate that an investor would have earned (or lost) on an investment in this Fund
(assuming  reinvestment of all dividends and  distributions).  This information
has been audited by KPMG LLP,  whose  report,  along with the Fund's  financial
statements, are included in the Annual Report, which is available upon request.

                                   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 the Fund's  assets in  convertible  securities,  which are bonds,
preferred stocks, and other securities that pay interest or dividends and offer
the buyer the ability to convert 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.

MONEY MARKET INSTRUMENTS

We may hold a certain  portion of the Fund's assets in  investment-grade,  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,
banker's  acceptances,  and  other  financial  institution  obligations.  These
securities may carry fixed or variable interest rates.

ILLIQUID SECURITIES

We may  invest  up to 15% of the  Fund's  net  assets  in  securities  that are
illiquid.  Illiquid securities are those securities which cannot be disposed of
in the ordinary course of business,  seven days or less, at  approximately  the
same value at which the Fund has valued the securities.

FORWARD CURRENCY CONTRACTS

We may hold  securities  denominated in foreign  currencies.  As a result,  the
value of these  securities  will be  affected by changes in the  exchange  rate
between the dollar and the foreign  currencies.  In managing currency exposure,
the Fund may enter into forward currency contracts. A forward currency contract
is 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 a foreign
currency and desires to "lock in" the U.S.  dollar price of that security until
settlement.

AMERICAN DEPOSITARY RECEIPTS (ADRS)

We may invest the Fund's  assets in ADRs,  which are  foreign  shares held by a
U.S.  bank that issues a receipt  evidencing  ownership.  Dividends are paid in
U.S. dollars.

GLOBAL DEPOSITARY RECEIPTS (GDRS)

We may invest the Fund's  assets in GDRs,  which are  foreign  shares held by a
U.S. or foreign bank that issues a receipt evidencing ownership.  Dividends are
paid in U.S. dollars.

                            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, Short-Term Bond, Science & Technology,  and First
Start Growth 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  valued  at the  last  quoted  sales  price,  or the most
       recently  determined closing price calculated  according to local market
       convention,  available  at the  time a Fund  is  valued.  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 that 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.

     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. There can be no assurance,  however, that the Fund will
at all times be able to maintain a constant $1 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 per  share  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

                                       2
<PAGE>
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 an NAV per
share by using available market quotations.

                     CONDITIONS OF PURCHASE AND REDEMPTION

NONPAYMENT

If any order to purchase shares is canceled due to nonpayment or if the Company
does not receive good funds either by check or electronic funds transfer,  USAA
Shareholder  Account Services (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 the 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  that 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 ten shares of the  Aggressive  Growth,  Growth,  Growth &
Income, Income Stock, Income,  Short-Term Bond, Science & Technology,  or First
Start Growth  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 the
account was  established,  (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 amounts of at
least $250.

     Checks  issued to  shareholders  of  either  Fund will be sent only to the
person 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  owner(s)  will be required on the check,  according to
the election made on the signature  card.  You will continue to earn  dividends
until the shares are redeemed by the presentation of a check.

     When a check is presented to the Transfer Agent for payment,  a sufficient
number of full and  fractional  shares  from your  account  will be redeemed to
cover the amount of the check.  If the account balance 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  is  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  a   non-governmental   employer,   an   income-producing
investment, or an account with a participating financial institution.

DIRECT DEPOSIT PROGRAM - The monthly  transfer of certain  federal  benefits to
directly  purchase  shares of a USAA mutual  fund.  Eligible  federal  benefits
include:  Social Security,  Supplemental Security Income, Veterans Compensation
and Pension,  Civil Service  Retirement  Annuity,  and Civil  Service  Survivor
Annuity.

GOVERNMENT  ALLOTMENT - The  transfer of  military  pay by the U.S.  Government
Finance Center for the purchase of USAA mutual fund shares.

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.  You may
initiate a "buy" or "sell" whenever you choose.

DIRECTED  DIVIDENDS  - If you own  shares  in more than one of the Funds in the
USAA  Family of Funds,  you may  direct  that  dividends  and/or  capital  gain
distributions  earned in one Fund be used to purchase shares  automatically  in
another fund.

                                       4
<PAGE>
     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 you own  shares  having  an NAV of  $5,000  or more in a  single  investment
account  (accounts in different  Funds cannot be aggregated  for this purpose),
you 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.

     This 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.  You are not charged  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  offers
403(b)(7)  accounts and various forms of IRAs. 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  sections  captioned  WHAT IS THE  FUND'S  INVESTMENT  OBJECTIVE  AND  MAIN
STRATEGY?   and  FUND  INVESTMENTS  in  each  Fund's  Prospectus  describe  the
fundamental  investment  objective(s) and the investment policies applicable to
each Fund.  Each  Fund's  objective(s)  cannot be changed  without  shareholder
approval. 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.

                                       5
<PAGE>
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.

     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  SEC  limitations
applicable to each Fund's  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 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  that, 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  that, 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 that 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  that 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 that 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 that 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

                                       7
<PAGE>
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.

     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,  Science & Technology,  and First Start Growth Funds 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.

     Each  Fund  may  enter  into   forward   currency   contracts   under  two
circumstances. First, when each 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 until  settlement.  By entering into
such a contract,  each 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
each 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.  Each 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.

                                       8
<PAGE>
     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 each 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 each 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  each 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 each Fund is obligated to deliver.

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

     Although  each 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 each Fund at one rate,
while offering a lesser rate of exchange  should the Fund desire to resell that
currency to the dealer.

INVESTMENTS IN REAL ESTATE INVESTMENT TRUSTS (REITS)

Because the Aggressive Growth,  Growth, Growth & Income,  Income, Income Stock,
Science &  Technology,  and First Start Growth 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  ability to  convert  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 (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.

REPURCHASE AGREEMENTS

Each Fund may  invest  in  repurchase  agreements  that are  collateralized  by
obligations  issued or guaranteed as to both principal and interest by the U.S.
government,  its agencies or  instrumentalities.  A  repurchase  agreement is a
transaction in which a security is purchased with a simultaneous commitment

                                       9
<PAGE>
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.  The
obligation  of the seller to pay the agreed upon price is in effect  secured by
the value of the underlying  security.  In these  transactions,  the securities
purchased by a Fund will have a total value equal to or in excess of the amount
of the  repurchase  obligation and will be held by the Fund's  custodian  until
repurchased.  If the seller  defaults and the value of the underlying  security
declines,  the Fund may  incur a loss and may incur  expenses  in  selling  the
collateral.  If  the  seller  seeks  relief  under  the  bankruptcy  laws,  the
disposition of the collateral may be delayed or limited.

TEMPORARY DEFENSIVE POLICY

Each Fund may on a temporary basis because of market,  economic,  political, or
other  conditions,  invest  up to  100%  of  its  assets  in  investment-grade,
short-term debt instruments.  Such securities may consist of obligations of the
U.S. government,  its agencies or instrumentalities,  and repurchase agreements
secured by such  instruments;  certificates of deposit of domestic banks having
capital,  surplus,  and undivided  profits in excess of $100 million;  banker's
acceptances  of  similar  banks;  commercial  paper  and other  corporate  debt
obligations.

                            INVESTMENT RESTRICTIONS

The following investment  restrictions have been adopted by the Company for and
are  applicable  to each Fund except the Science &  Technology  and First Start
Growth Funds,  which are listed  separately  below.  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 may not:

 (1)   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)   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)   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)   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)   Invest in companies for the purpose of exercising control or management.

 (6)   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.

 (7)   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)   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)   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
<PAGE>
(10)   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)   Acquire  securities of other open-end  investment  companies,  except in
       connection  with a  merger,  consolidation,  or  acquisition  of  assets
       approved by the shareholders.

(12)   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)   Purchase  or sell  commodities,  commodity  contracts,  or real  estate,
       although a Fund may invest in the  securities of real estate  investment
       trusts.

(14)   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)   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)   Change the  nature of its  business  so as to cease to be an  investment
       company.

(17)   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.

     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.

Each of the Science & Technology and First Start Growth Funds may not:

 (1)   With respect to 75% of its total assets,  purchase the securities of any
       issuer (except U.S.  government  securities,  as such term is defined in
       the 1940  Act)  if,  as a  result,  it  would  own more  than 10% of the
       outstanding  voting securities of such issuer or it would have more than
       5% of the value of its total assets  invested in the  securities of such
       issuer.

 (2)   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).

 (3)   Invest 25% or more of the value of its total assets in any one industry;
       provided,  this  limitation  does not  apply  to  securities  issued  or
       guaranteed by the U.S. government and its agencies or instrumentalities.

 (4)   Issue senior securities, except as permitted under the 1940 Act.

 (5)   Underwrite securities of other issuers, except to the extent that it may
       be deemed to act as a statutory  underwriter in the  distribution of any
       restricted securities or not readily marketable securities.

 (6)   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.

 (7)   Purchase  or sell  commodities,  except  that  each  Fund may  invest in
       financial futures contracts, options thereon, and similar instruments.

 (8)   Purchase or sell real estate unless acquired as a result of ownership of
       securities  or other  instruments,  except  that each Fund may invest in
       securities or other  instruments  backed by real estate or securities of
       companies  that deal in real  estate or are  engaged in the real  estate
       business.

     With respect to each Fund's concentration policies as described above, 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.

                                      11
<PAGE>
ADDITIONAL RESTRICTION

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

     Each Fund 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.

     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  commissions  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.

     The Company pays no brokerage commissions as such for debt securities. The
market for such securities is typically a "dealer"  market in which  investment
dealers buy and sell the  securities  for their own  accounts,  rather than for
customers,  and the price may  reflect a  dealer's  mark-up  or  mark-down.  In
addition, some securities may be purchased directly from issuers.

     During the fiscal year ended July 31, 1999, the Funds purchased securities
of the following regular broker-dealers (the ten largest broker-dealers through
whom the Fund purchased securities) or the parents of regular broker-dealers.

         respectively, of brokerage fees paid by each Fund.

     For the year ended July 31, 1999, 13.52%,  8.99% 6.69%, 36.71%, and 44.47%
of the  aggregate  dollar  amounts of  transactions  involving  the  payment of
commissions by the Growth, Growth & Income, Income Stock, Science & Technology,
and  First  Start  Growth  Funds,  respectively,  were  effected  through  USAA
Brokerage Services.

     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  $2,271,661,
$266,589,373, $184,562,804, $307,128,773, $46,184,032, and $28,048,334, and the
related  brokerage   commissions  or  underwriting   commissions  were  $3,500,
$281,825,  $177,700,  $370,801, $50,785, and $30,840 for the Aggressive Growth,
Growth,  Growth & Income,  Income Stock, Science & Technology,  and First Start
Growth Funds, respectively for the year ended July 31, 1999.

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,  Short-Term Bond,  Science & Technology,  and First Start Growth 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  objective(s).  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                             1998              1999
       ----                             ----              ----
       Aggressive Growth               83.32%            35.18%
       Growth                          68.93%            39.60%
       Growth & Income                 29.38%            24.53%
       Income Stock                    22.34%            34.20%
       Income*                         47.35%            54.02%
       Short-Term Bond                 48.24%            11.53%
       Science & Technology            76.31%            44.39%
       First Start Growth              52.11%            26.64%

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

     *   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,

                             DESCRIPTION OF SHARES

The Funds are a series of the  Company and are  diversified.  The Company is an
open-end management investment company incorporated under the laws of the state
of Maryland on October 14, 1980.  The Company is  authorized to issue shares in
separate series or Funds. There are thirteen mutual funds in the Company,  nine
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.  The Science & Technology  and First Start Growth
Funds were  established by the Board of Directors on May 9, 1997, and commenced
public offering of their shares on August 4, 1997.

                                      14
<PAGE>
     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  circumstances,  however,
shareholders  may apply for  shareholder  information  to obtain  signatures to
request a special  shareholder  meeting.  The Company 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.  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.
The  Company  will  assist in  communicating  to other  shareholders  about the
meeting.  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  that  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)  and  (2)   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 or she 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.

(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, 1999,  the USAA Family of Funds  consisted of four  registered
     investment companies offering 35 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  available to the public only
     through the purchase of certain  variable  annuity  contracts and variable
     life insurance policies offered by 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
in the  USAA  Family  of  Funds.  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 October 29, 1999, 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 October 29, 1999, USAA and its affiliates  owned  51,276,665  shares
(34.5%) of the S&P 500 Index Fund; 6,639,115 shares (5.36%) of the Income Stock
Fund; 3,535,904 shares (0.1%) of the Money Market Fund; 1,211,086 shares (4.8%)

Fund;  2,100,010 shares (62.8%) of the Intermediate  Term Bond Fund;  2,100,010
shares (74.5%) of the High Yield Opportunities  Fund;  2,000,010 shares (56.1%)
of the Small Cap Stock  Fund;  and no  shares of the  Aggressive  Growth  Fund,
Growth Fund, Growth & Income Fund, Income Fund and Science & Technology Fund.

     The Company knows of no other persons who, as of October 31, 1999, 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, a wholly owned indirect  subsidiary of United Services
Automobile   Association  (USAA),  a  large,   diversified  financial  services
institution, 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,  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  $40  billion,  of which
approximately $28 billion were in mutual fund portfolios.

     While the officers and  employees of the Manager,  as well as those of the
Funds, may engage in personal securities  transactions,  they are restricted by
the  procedures in a Joint Code of Ethics adopted by the Manager and the Funds.
The  Joint  Code of  Ethics  was  designed  to  ensure  that the  shareholders'
interests come before the individuals who manage their Funds. It also prohibits
the portfolio managers and other investment personnel from buying securities in
an initial  public  offering or from profiting from the purchase or sale of the
same security within 60 calendar days.  Additionally,  the Joint Code of Ethics
requires the  portfolio  manager and other  employees  with access  information
about the purchase or sale of securities by the Funds to obtain approval before
executing permitted personal trades.

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.

                                      19
<PAGE>
     Except for the services and facilities provided by the Manager,  each Fund
pays all other expenses incurred in its operation. Expenses for which each Fund
is  responsible  includes  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 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, 2000, 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%,  the Money Market Fund to .46%,
and the First Start  Growth  Fund to 1.65% of each  Fund's  ANA,  respectively,
until December 1, 2000, and will reimburse the Funds for all expenses in excess
of such  limitations.  After December 1, 2000, 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:

UNDERWRITER

agreement  provides that the Manager will receive no fee or other  compensation

                        CALCULATION OF PERFORMANCE DATA

Information regarding the total return and yield of each Fund is provided under
COULD THE VALUE OF YOUR  INVESTMENT IN THE FUND  FLUCTUATE?  in its Prospectus.
See VALUATION OF SECURITIES  herein for a discussion of the manner in which the
Funds' 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 and income other than investment
income, 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 the
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 July 31, 1999, was 4.77%.
       Effective Yield For 7-day Period ended July 31, 1999, was 4.70%.

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[((a-b)/(cd)+1)^6 -1]

  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 30-day yields for the period ended July 31, 1999,  for the Income Fund
and Short-Term Bond Fund were 6.54% and 6.48%, respectively.

                                      21
<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 the 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 the 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

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

1.  LONG-TERM DEBT RATINGS:

MOODY'S INVESTOR SERVICE

Aaa      Bonds  that 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  that  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 that 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 that suggest a  susceptibility  to  impairment
         sometime in the future.

Baa      Bonds that 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.

                                      22
<PAGE>
Ba       Bonds that 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  both  good and bad times  over the  future.
         Uncertainty of position characterizes bonds in this class.

B        Bonds that 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 that 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 that 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 that 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.

NOTE:  MOODY'S APPLIES  NUMERICAL  MODIFIERS 1, 2, AND 3 IN EACH GENERIC RATING
CLASSIFICATION.  THE  MODIFIER 1  INDICATES  THAT THE  OBLIGATION  RANKS IN THE
HIGHER END OF ITS GENERIC RATING CATEGORY, THE MODIFIER 2 INDICATES A MID-RANGE
RANKING,  AND THE  MODIFIER  3  INDICATES  A  RANKING  IN THE LOWER END OF THAT
GENERIC RATING CATEGORY.

STANDARD & POOR'S RATINGS GROUP

AAA      An obligation  rated "AAA" has the highest rating assigned by Standard
         & Poor's. The obligor's  capacity to meet its financial  commitment on
         the obligation is extremely strong.

AA       An obligation rated "AA" differs from the highest rated issues only in
         small degree. The obligor's capacity to meet its financial  commitment
         on the obligation is VERY STRONG.

A        An obligation  rated "A" is somewhat more  susceptible  to the adverse
         effects of changes  in  circumstances  and  economic  conditions  than
         obligations  in  higher  rated  categories.   However,  the  obligor's
         capacity to meet its financial  commitment on the  obligation is still
         STRONG.

BBB      An obligation rated "BBB" exhibits  adequate  capacity to pay interest
         and repay principal.  However, adverse economic conditions or changing
         circumstances  are more  likely to lead to a weakened  capacity of the
         obligor to meet its financial commitment on the obligation.

         Obligations  rated  "BB," "B,"  "CCC,"  "CC," and "C" are  regarded as
         having  significant  speculative  characteristics.  "BB" indicates the
         least  degree  of  speculation   and  "C"  the  highest.   While  such
         obligations   will   likely   have   some   quality   and   protective
         characteristics,  these may be  outweighed by large  uncertainties  or
         major exposures to adverse conditions.

BB       An obligation  rated "BB" is LESS  VULNERABLE to nonpayment than other
         speculative issues.  However, it faces major ongoing  uncertainties or
         exposure to adverse business,  financial, or economic conditions which
         could lead to the obligor's  inadequate capacity to meet its financial
         commitment on the obligation.

B        An  obligation  rated  "B"  is  MORE  VULNERABLE  to  nonpayment  than
         obligations  rated "BB," but the obligor currently has the capacity to
         meet its financial  commitment on the  obligation.  Adverse  business,
         financial,  or economic  conditions  will likely  impair the obligor's
         capacity  or  willingness  to meet  its  financial  commitment  on the
         obligation.

CCC      An obligation rated "CCC" is CURRENTLY  VULNERABLE to nonpayment,  and
         is  dependent  upon  favorable  business,   financial,   and  economic
         conditions  for the obligor to meet its  financial  commitment  on the
         obligation.  In the event of adverse business,  financial, or economic
         conditions, the obligor is not likely to have the capacity to meet its
         financial commitment on the obligation.

CC       An obligation rated "C" is CURRENTLY HIGHLY VULNERABLE to nonpayment.

C        The "C" rating  may be used to cover a  situation  where a  bankruptcy
         petition has been filed or similar action has been taken, but payments
         on this obligation are being continued.

D        An obligation rated "D" is in payment default. The "D" rating category
         is used when  payments on an  obligation  are not made on the date due
         even if the applicable grace period has not expired, unless Standard &
         Poor's  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 or the taking of a similar  action if payments on
         an obligation are jeopardized.

                                      23
<PAGE>
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 IBCA

AAA      Highest credit quality. "AAA" ratings denote the lowest expectation of
         credit risk.  They are assigned only in case of  exceptionally  strong
         capacity for timely payment of financial commitments. This capacity is
         highly unlikely to be adversely affected by foreseeable events.

AA       Very high credit  quality.  "AA" ratings denote a very low expectation
         of credit risk.  They indicate very strong capacity for timely payment
         of  financial   commitments.   This  capacity  is  not   significantly
         vulnerable to foreseeable events.

A        High credit  quality.  "A" ratings denote a low  expectation of credit
         risk.  The capacity for timely  payment of  financial  commitments  is
         considered strong. This capacity may, nevertheless, be more vulnerable
         to changes in circumstances or in economic conditions than is the case
         for higher ratings.

BBB      Good credit quality.  "BBB" ratings indicate that there is currently a
         low  expectation  of credit risk.  The capacity for timely  payment of
         financial  commitments is considered adequate,  but adverse changes in
         circumstances  and in  economic  conditions  are more likely to impair
         this capacity. This is the lowest investment-grade category.

PLUS (+) MINUS(-)  SIGNS ARE USED WITH A RATING SYMBOL TO INDICATE THE RELATIVE
POSITION OF A CREDIT WITHIN THE RATING CATEGORY. PLUS AND MINUS SIGNS, HOWEVER,
ARE NOT USED IN THE AAA CATEGORY.

DUFF & PHELPS CREDIT RATING CO.

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 senior short-term  obligations.
           The effect of industry  characteristics  and market compositions 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  broad-based access to the market for
                refinancing.

                                      24
<PAGE>
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  security
                elements 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 issued designated A-1.

A-3      Issues  carrying this  designation  have adequate  capacity for timely
         payment.  They are, however, 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 IBCA

F1       Highest credit  quality.  Indicates the strongest  capacity for timely
         payment of financial commitments;  may have an added "+" to denote any
         exceptionally strong credit feature.

F2       Good credit  quality.  A  satisfactory  capacity for timely payment of
         financial commitments,  but the margin of safety is not as great as in
         the case of the higher ratings.

F3       Fair credit  quality.  The  capacity  for timely  payment of financial
         commitments  is adequate;  however,  near-term  adverse  changes could
         result in a reduction to non-investment grade.

DUFF & PHELPS CREDIT RATING CO.

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.

                       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.

              agent  or   employee   against   judgments,   penalties,   fines,
              settlements and reasonable  expenses  actually incurred by him in
              connection  with any  proceeding in which he is a party by reason
              of having served as a director, officer, agent or employee, if he
              acted in good faith and reasonably believed that, (i) in the case
              of conduct in his official capacity with the Registrant, that his
              conduct was in the best interests of the  Registrant,  or (ii) in
              all other cases, that his conduct was at least not opposed to the
              best  interests  of the  Registrant.  In the case of any criminal
              proceeding,  said  director,  officer,  agent or employee must in
              addition have had no reasonable cause to believe that his conduct
              was  unlawful.  In the case of a proceeding by or in the right of
              the  Registrant,   indemnification   may  only  be  made  against
              reasonable  expenses  and  may  not be  made  in  respect  of any
              proceeding  in which the  director,  officer,  agent or  employee
              shall  have been  adjudged  to be liable to the  Registrant.  The
              termination  of any  proceeding by judgment,  order,  settlement,
              conviction,  or upon a plea of nolo  contendere or its equivalent
              creates a  rebuttable  presumption  that the  director,  officer,
              agent or employee did not meet the requisite  standard of conduct
              for indemnification. No indemnification may be made in respect of
              any  proceeding   charging   improper  personal  benefit  to  the
              director,  officer,  agent or employee  whether or not  involving
              action in such  person's  official  capacity,  if such person was
              adjudged to be liable on the basis that improper personal benefit
              was received.  If such  director,  officer,  agent or employee is
              successful,  on the merits or  otherwise,  in defense of any such
              proceeding  against  him,  he shall be  indemnified  against  the
              reasonable expenses incurred by him (unless such  indemnification
              is  limited  by  the  Registrant's  charter,  which  it is  not).
              Additionally,  a court  of  appropriate  jurisdiction  may  order
              indemnification in certain  circumstances even if the appropriate
              standard of conduct set forth above was not met.

                                      c-6
<PAGE>
              Indemnification may not be made unless authorized in the specific
              case after  determination that the applicable standard of conduct
              has been met. Such determination shall be made by either: (i) the
              board of  directors  by either  (x) a  majority  vote of a quorum
              consisting of directors  not parties to the  proceeding or (y) if
              such a quorum  cannot be obtained,  then by a majority  vote of a
              committee of the board consisting solely of two or more directors
              not  at the  time  parties  to  such  proceeding  who  were  duly
              designated  to act in the matter by a  majority  vote of the full
              board in which  the  designated  directors  who are  parties  may
              participate;  (ii) special legal counsel selected by the board of
              directors or a committee of the board by vote as set forth in (i)
              above,  or,  if the  requisite  quorum  of the  board  cannot  be
              obtained therefore and the committee cannot be established,  by a
              majority  vote of the  full  board  in  which  directors  who are
              parties may participate; or (iii) the stockholders.

              Reasonable  expenses may be reimbursed or paid by the  Registrant
              in  advance  of  final   disposition  of  a  proceeding  after  a
              determination,  made in accordance  with the procedures set forth
              in the  preceding  paragraph,  that the facts then known to those
              making the determination would not preclude indemnification under
              the applicable  standards provided the Registrant  receives (i) a
              written  affirmation  of the  good  faith  belief  of the  person
              seeking  indemnification  that the applicable standard of conduct
              necessary  for  indemnification  has been met, and (ii) a written
              undertaking  to  repay  the  advanced  sums  if it is  ultimately
              determined  that the applicable  standard of conduct has not been
              met.

              Insofar as  indemnification  for  liabilities  arising  under the
              Securities  Act of 1933 may be permitted to  directors,  officers
              and  controlling  persons  of  the  Registrant  pursuant  to  the
              Registrant's   Articles  of  Incorporation   or  otherwise,   the
              Registrant   has  been  advised  that,  in  the  opinion  of  the
              Securities  and  Exchange  Commission,  such  indemnification  is
              against public policy as expressed in the Act and is,  therefore,
              unenforceable.  In the  event  that a claim  for  indemnification
              against  such   liabilities   (other  than  the  payment  by  the
              Registrant of expenses incurred or paid by a director, officer or
              controlling person of the Registrant in the successful defense of
              any action,  suit or  proceeding)  is asserted by such  director,
              officer or controlling  person in connection  with the securities
              being registered, then the Registrant will, unless in the opinion
              of its  counsel  the  matter has been  settled  by a  controlling
              precedent,  submit  to a court of  appropriate  jurisdiction  the
              question  of  whether  indemnification  by it is  against  public
              policy as  expressed in the Act and will be governed by the final
              adjudication of such issue.
