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 to seek high current  return,  with reduced
risk over time, through an asset allocation  strategy that emphasizes income and
gives  secondary  emphasis to long-term  growth of capital.  Using preset target
ranges,  we will  invest  the  Fund's  assets  mostly in bonds,  and to a lesser
extent, stocks and money market instruments.

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, interest rate risk,
and market 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 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   MARKET RISK involves the possibility  that the Fund's  investments in stocks
    will  decline  in a down stock  market,  reducing  the value of a  company's
    stock, regardless of the success or failure of that company's operations.

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

                                       2
<PAGE>
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.

 A  The Fund's principal strategy is to provide a diversified investment program
    within one mutual  fund by  allocating  its assets in each of the  following
    investment categories according to the following targeted ranges. Securities
    are classified by category at the time of purchase.

[PIE CHART]
                               PERCENTAGE TARGET RANGE
                                    OF NET ASSETS

       INVESTMENT CATEGORY

    MONEY MARKET INSTRUMENTS              0-10%

The ranges  allow for a variance  within each  investment  category.  The Fund's
Board of  Trustees  may revise the target  ranges  upon 60 days'  prior  written
notice to  shareholders.  However,  we may go outside  the ranges on a temporary
defensive basis without  shareholder  notification  whenever we believe it is in
the best interest of the Fund and its shareholders.

 Q  Why are stocks and bonds mixed in the same Fund?

 A  From time to time the stock and bond markets may fluctuate  independently of
    each other.  In other  words,  a decline in the stock market may, in certain
    instances,  be  offset by a rise in the bond  market,  or vice  versa.  As a
    result,  the Fund, with its mix of stocks and bonds, is expected in the long
    run to entail less market risk (and  potentially  less return) than a mutual
    fund investing exclusively in stocks.

 Q  Why were these investment categories and target ranges selected?

 A  The  investment  categories  and  target  ranges  were  selected  to provide
    investors  with a  diversified  investment  in a single  mutual fund.  Bonds
    provide a high  current  return  while  stocks  provide  the  potential  for
    long-term  capital  growth.  Money  market  instruments  provide a means for
    temporary  investment  of cash  balances  arising  in the  normal  course of
    business. Primary emphasis for this Fund is income.

    However,  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.

 Q  What  actions  are taken to keep the  Fund's  asset  allocations  within the
    target ranges?

 A  If  market  action  causes  the  actual  assets  of the  Fund in one or more
    investment  categories to move outside the ranges,  we will make adjustments
    to rebalance the portfolio.  In general,  we will rebalance the portfolio at
    least once during each quarter. In rebalancing the Fund's portfolio, we will
    buy or sell securities to return the actual  allocation of the Fund's assets
    to within its target ranges. For example, the Fund's portfolio could begin a
    quarter with its assets  allocated  80% in bonds,  15% in stocks,  and 5% in
    money market  instruments.  During the quarter,  due to market returns,  the
    Fund's  portfolio  could hold 90% in bonds,  5% in  stocks,  and 5% in money
    market  instruments.  In this case, we would sell bonds and use the proceeds
    to buy stocks to bring bonds and stocks back to within their target ranges.

[CAUTION LIGHT]
REBALANCING RISK. In purchasing and selling securities in order to rebalance its
portfolio, the Fund will pay more in brokerage commissions than it would without
a rebalancing  policy.  As a result of the need to rebalance,  the Fund also has
less  flexibility  in the timing of purchases  and sales of  securities  than it
would  otherwise.  While we will attempt to minimize  any adverse  impact to the
Fund or its shareholders, the Fund may have a higher proportion of capital gains
and a lower return than a fund that does not have a rebalancing policy.

Bonds and Money Market Instruments

 Q  What types of bonds are included in the Fund's portfolio?

 A  Bonds must be  investment  grade at the time of purchase and may include any
    of the following:

    o  obligations of the U.S. government, its agencies and instrumentalities;
    o  mortgage-backed securities;
    o  asset-backed securities;
    o  corporate debt securities, such as notes and bonds;
    o  debt securities of real estate investment trusts;
    o  obligations  of state  and  local  governments  and  their  agencies  and
       instrumentalities;
    o  Eurodollar obligations;
    o  Yankee obligations; and
    o  other debt securities.

    For a further description of these securities, see APPENDIX A on page 24.

[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.

                                       8
<PAGE>
 Q  What are considered investment-grade securities?

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

   ==========================================================================
                                    Long-term               Short-term
       Rating Agency             debt securities          debt securities
   ==========================================================================
     Moody's Investors                                   At least Prime-3 or
      Services, Inc.              At least Baa           MIG 4/VMIG 4
   --------------------------------------------------------------------------
     Standard & Poor's
      Ratings Group               At least BBB           At least A-3 or SP-2
   --------------------------------------------------------------------------
     Fitch IBCA, Inc.             At least BBB           At least F-3
   --------------------------------------------------------------------------
     Duff and Phelps              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.

[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.

                                       9
<PAGE>
 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 Trustees.

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

 A  We buy bonds that represent value in 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 security is available.

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

 A  The  money  market   instruments   included  in  the  Fund's  portfolio  are
    investment-grade,   U.S.   dollar-denominated   debt  securities  that  have
    remaining  maturities  of one year or less.  They may carry  either fixed or
    variable interest rates and may include any of the following:

    o  obligations of the U.S. government, its agencies and instrumentalities;
    o  repurchase agreements collateralized by the same;
    o  commercial paper or other short-term corporate obligations;
    o  certificates of deposit;
    o  bankers' acceptances; and
    o  other suitable obligations.

Stocks

 Q  What types of stocks are included in the Fund's portfolio?

 A  We will  invest  this  portion  of the  Fund's  portfolio  substantially  in
    domestic common stocks. To a much lesser extent, we may include some foreign
    stocks and real estate investment trusts (REITs).

                                       10
<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 are the decisions to buy and sell stocks made?

 A  We generally invest in companies that are, or have the prospect of becoming,
    dominant  in their  industry.  We expect  the sales  and  earnings  of these
    companies to grow faster than those of their industry  peers.  We consider a
    number of factors such as:

    o  a company's strategic position in its industry,
    o  sales and earnings growth,
    o  cash flow,
    o  book value, and
    o  dividend yield.

    We will sell a security when we perceive that our original investment thesis
    no longer holds.

For  additional  information  about other  securities in which we may invest the
Fund's assets, see APPENDIX A on page 24.

USING MUTUAL FUNDS IN AN
ASSET ALLOCATION PROGRAM

I. The Idea Behind Asset Allocation

If you have money to invest and hear that stocks may be a good investment, is it
a wise idea to use your entire savings to buy one stock? Most people wouldn't --
it would be fortunate if it works, but this strategy holds a great deal of risk.
Surprising  news could be reported  tomorrow on your stock,  and its price could
soar or plummet.

Careful  investors  understand  this  concept  of risk and  lower  that  risk by
diversifying their holdings among a number of securities.  That way bad news for
one security may be counterbalanced by good news regarding other securities. But
there is still a  question  of risk  here.  History  tells  us that  stocks  are
generally more volatile than bonds and that  long-term  bonds are generally more
volatile  than  short-term  bonds.  History  also  tells us that over many years
investments  having  higher risks tend to have higher  returns than  investments
that  carry  lower  risks.  From  these  observations  comes  the  idea of asset
allocation.

Asset  allocation is a concept that  involves  dividing your money among several
different  types of investments -- for example,  stocks,  bonds,  and short-term
investments  such as money market  instruments  -- and keeping  that  allocation
until your objectives or the financial markets  significantly  change.  That way
you're not pinning  all your  financial  success on the  fortunes of one kind of
investment.  Money spread across  different  investment  categories can help you
reduce market risk and likely will provide more stability to your total return.

Asset  allocation  can work because  different  kinds of  investments  generally
follow  different  up-and-down  cycles.  With a variety of  investments  in your
portfolio, some are probably doing well, even when others are struggling.

II. Using Asset Allocation in an Investment Program

Most investors  understand the concept of diversification,  but asset allocation
goes beyond  diversifying your portfolio;  it's a much more active process.  You
must evaluate your  lifestyle,  finances,  circumstances,  long- and  short-term
financial  goals,  and tolerance for investment  risk.  Once you have structured
your  allocation,  you'll need to review it regularly since your objectives will
change over time. Even though we do not charge sales loads or  commissions,  our
member service representatives are always available to assist you in structuring
and reviewing your investment portfolio.

III. USAA's Series of Asset Strategy Funds

USAA's series of asset allocation  funds, our Asset Strategy Funds, are designed
for the long-term  investor and are in line with our  investment  philosophy for
investors, specifically "buy and hold for the long-term," and "don't try to time
the market." As shown below,  each of USAA's  Asset  Strategy  Funds has its own
different mix of assets and objectives.

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.

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

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   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 $900, 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 18.

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).

                                   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  supervision  of the Fund's
Board of Trustees,  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 Trustees. Securities that

                                       20
<PAGE>
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 Trustees.

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  quarterly.  Any net capital gain
distribution  usually occurs within 60 days of the May 31 fiscal year end, which
would be  somewhere  around  the end of  July.  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.  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.

                                       21
<PAGE>

Regardless of the length of time you have held 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 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 the 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.

<PAGE>
                                   APPENDIX A

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

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.

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.

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.

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

                                       24
<PAGE>
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.

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.

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

                                       25
<PAGE>
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 Trustees or its  delegate has
determined that they are of credit quality  comparable to the debt securities in
which the Fund generally may invest.

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).

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.

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.

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.

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

The  Fund's  investment  objective  is to seek a  conservative  balance  for the
investor  between  income,  the majority of which is exempt from federal  income
tax, and the potential for  long-term  growth of capital to preserve  purchasing
power.  Using  preset  target  ranges,  we will  invest a majority of the Fund's
assets in  tax-exempt  bonds and money market  instruments  and the remainder in
blue chip stocks.  We manage the Fund with the goal of minimizing  the impact of
federal income taxes to shareholders.

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, 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   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 Fund's  investments in stocks
    will  decline  in a down stock  market,  reducing  the value of a  company's
    stock, regardless of the success or failure of that company's operations.

Other risks of the Fund described  later in the Prospectus  include  rebalancing
risk and the risks of changes in tax laws  impacting  the Fund's  dividends  and
distributions.  As with  other  mutual  funds,  losing  money  is also a risk of
investing in this Fund.

                                       2

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.

FUND INVESTMENTS

Principal Investment Strategies and Risks

 Q  What is the Fund's principal investment strategy?

 A  The Fund's principal strategy is to provide a diversified investment program
    within one mutual  fund by  allocating  its assets in each of the  following
    investment categories according to the following targeted ranges. Securities
    are classified by category at the time of purchase.

[PIE CHART]
                                PERCENTAGE TARGET RANGE
    INVESTMENT CATEGORY              OF NET ASSETS

    TAX-EXEMPT BONDS                    41-59%
    BLUE CHIP STOCKS                    41-49%
    TAX-EXEMPT MONEY
    MARKET INSTRUMENTS                   0-10%
     (Maturities of one
     year or less)

The ranges  allow for a variance  within each  investment  category.  The Fund's
Board of  Trustees  may revise the target  ranges  upon 60 days'  prior  written
notice to  shareholders.  However,  we may go outside  the ranges on a temporary
defensive basis without  shareholder  notification  whenever we believe it is in
the best interest of the Fund and its shareholders.

                                       6
<PAGE>
 Q  Why are stocks and bonds mixed in the same Fund?

 A  From time to time the stock and bond markets may fluctuate  independently of
    each other.  In other  words,  a decline in the stock market may, in certain
    instances,  be  offset by a rise in the bond  market,  or vice  versa.  As a
    result,  the Fund, with its mix of stocks and bonds, is expected in the long
    run to entail less market risk (and  potentially  less return) than a mutual
    fund investing exclusively in stocks.

 Q  Why were these investment categories and target ranges selected?

 A  The  investment  categories  and  target  ranges  were  selected  to provide
    investors with a diversified  investment in a single mutual fund. Tax-exempt
    bonds  provide  income  exempt from  federal  income  tax.  Blue chip stocks
    provide the potential for long-term capital growth.  Tax-exempt money market
    instruments  provide  a means  for  temporary  investment  of cash  balances
    arising in the normal course of business.

    During normal market conditions,  the Fund's assets will be invested so that
    at least  50% of the  Fund's  annual  income  will be  exempt  from  federal
    personal income tax and excluded from the calculation of federal alternative
    minimum taxes for individual taxpayers. This policy may only be changed by a
    shareholder vote.

    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  taxable or tax-exempt debt instruments.  This
    may result in the Fund not achieving  its  investment  objective  during the
    time it is in this temporary defensive posture.

 Q  How will the  impact of  federal  income  taxes be  minimized  on the Fund's
    shareholders?

 A  We intend to use various techniques to minimize the impact of federal income
    taxes on the Fund's  shareholders  while  maximizing  capital  appreciation,
    including:

    o  investing in bonds and similar  instruments  that provide income which is
       exempt from federal income tax;

    o  investing in a portfolio of blue chip stocks with a low dividend yield;

                                       7
<PAGE>
    o  selecting  blue chip  stocks that we expect to hold for  relatively  long
       periods to minimize the cost of trading and the receipt of capital gains;

    o  when selling  securities,  considering the sale of those with the highest
       tax cost basis to minimize the receipt of capital gains; and

    o  offsetting   capital  gains  with  capital   losses,   if  available  and
       appropriate.

    Although the Fund seeks to minimize  taxable  income and the  realization of
    capital gains, the Fund may nevertheless  receive taxable income and capital
    gains from time to time. Additionally, you may owe taxes on realized capital
    gains, if any, when you redeem your Fund shares.

[CAUTION LIGHT]

CHANGES  IN TAX  LAWS.  The  target  ranges  of  securities  categories  and the
techniques for  minimizing the impact of taxes are all based on current  federal
tax law. Any future changes in those laws could result in significant changes in
the Fund's investment strategies and techniques.

 Q  What  actions  are taken to keep the  Fund's  asset  allocations  within the
    target ranges?

 A  If  market  action  causes  the  actual  assets  of the  Fund in one or more
    investment  categories to move outside the ranges,  we will make adjustments
    to rebalance the portfolio.  In general,  we will rebalance the portfolio at
    least once during each quarter. In rebalancing the Fund's portfolio, we will
    buy or sell securities to return the actual  allocation of the Fund's assets
    to within its target ranges. For example, the Fund's portfolio could begin a
    quarter with its assets allocated 50% in tax-exempt  bonds, 45% in blue chip
    stocks, and 5% in tax-exempt money market instruments. During the quarter, a
    strong  stock  market  coupled  with a weak  bond  market  could  leave  the
    portfolio with 40% in tax-exempt  bonds, 55% in blue chip stocks,  and 5% in
    tax-exempt money market  instruments.  In this case, we would sell blue chip
    stocks and use the proceeds to buy  tax-exempt  securities to bring the blue
    chip stocks and tax-exempt bonds back to within their target ranges.

[CAUTION LIGHT]
REBALANCING RISK. In purchasing and selling securities in order to rebalance its
portfolio, the Fund will pay more in brokerage commissions

                                       8
<PAGE>
than  it  would  without  a  rebalancing  policy.  As a  result  of the  need to
rebalance,  the Fund also has less  flexibility  in the timing of purchases  and
sales of securities  than it would  otherwise.  Although we intend to manage the
Fund in a  tax-advantaged  manner,  the Fund may  have a  higher  proportion  of
capital  gains and a lower  return than a fund that does not have a  rebalancing
policy.

Tax-Exempt Bonds and
Tax-Exempt Money Market Instruments

 Q  What are tax-exempt securities?

 A  Tax-exempt  securities  include  municipal debt  obligations  that have been
    issued by states  and their  political  subdivisions,  and duly  constituted
    state and local authorities and corporations as well as securities issued by
    certain U.S.  territories  or  possessions,  such as Puerto Rico, the Virgin
    Islands,  and Guam. They are issued to fund public  infrastructure  projects
    such as streets and highways,  schools, water and sewer systems,  hospitals,
    and  airports.  Tax-exempt  securities  may  also  be  issued  to  refinance
    outstanding  obligations  as well as to obtain  funds for general  operating
    expenses and for loans to other public institutions and facilities.

    Because the projects benefit the public, Congress has granted exemption from
    federal income taxes for the interest income arising from these securities.

 Q  What types of tax-exempt securities are included in the Fund's portfolio?

 A  The Fund's  portfolio  may be  invested in any of the  following  tax-exempt
    securities.

    o  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;

    o  revenue  bonds,  which  are  payable  from  the  revenue  derived  from a
       particular  facility  or class of  facilities  or,  in some  cases,  from
       proceeds of a special excise tax or other specific  revenue  source,  but
       not from the general taxing power; or

    o  industrial  development bonds, which are issued by or on behalf of public
       authorities to obtain funds for privately-operated facilities.

                                       9
<PAGE>
 Q  What is the  average  maturity of the  securities  in the  Tax-Exempt  Bonds
    category and how is it calculated?

 A  The Tax-Exempt Bonds category includes tax-exempt  securities that will have
    a remaining maturity at the time of purchase of more than one year. Although
    the average  maturity of the securities in this category is not  restricted,
    we expect it to exceed ten years.  In determining a security's  maturity for
    purposes of calculating the Fund's average maturity, we may use estimates of
    the expected  time for its principal to be paid.  This can be  substantially
    shorter than its stated final  maturity.  For a discussion  on the method of
    calculating  the  average  weighted  maturity of the Fund's  portfolio,  see
    INVESTMENT POLICIES in the Statement of Additional Information.

[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.

 Q  What types of tax-exempt money market instruments are included in the Fund's
    portfolio?

 A  The tax-exempt money market instruments in the portfolio are tax-exempt debt
    securities  like the type included in the Tax-Exempt  Bonds  category.  They
    have remaining stated maturities at the time of purchase of one year or less
    or are subject to puts or similar demand features  resulting in an effective
    maturity of one year or less.

 Q  What are the credit ratings of these securities?

 A  First,  we will only  purchase  tax-exempt  securities  that are  considered
    investment grade. For a security to be considered  investment grade, it must
    be:

    o  rated by one or more  rating  agencies  at least  in the  fourth  highest
       rating category for long-term securities;

                                       10
<PAGE>
    o  rated by one or more rating  agencies at least within the second  highest
       rating category for short-term securities;

    o  or, if not rated by those rating agencies,  we must determine it to be of
       equivalent investment quality.

    And  second,  at  least  50% of the  combined  total  market  values  of the
    tax-exempt  bonds and  tax-exempt  money  market  instruments  will be rated
    within the three highest long-term rating categories by:

    o  Moody's Investors Service, Inc. (Moody's),
    o  Standard & Poor's Ratings Group (S&P), or
    o  Fitch Investors Service, Inc. (Fitch);

    or in the highest short-term rating category by:

    o Moody's,  S&P,  or Fitch.  If unrated  by those  three  agencies,  we must
      determine that the securities are of equivalent investment quality.

[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.

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

                                       11
<PAGE>
    holdings in such  securities to 5% or less of the Fund's net assets,  unless
    otherwise directed by the Fund's Board of Trustees.

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

 A  We will buy securities that offer an attractive balance of tax-exempt income
    against  credit  risk and price  volatility.  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.

Blue Chip Stocks

 Q  What types of stocks are included in the Fund's portfolio?

 A  We will invest in common stocks of blue chip companies for long-term growth.
    A blue chip company is one that has a market capitalization of:

    o  at least $500 million and is included in the list of companies  that make
       up the Standard & Poor's 500 Composite Stock Price Index or the Dow Jones
       Industrial Average; or

    o  at least $1 billion.

    We may invest up to 5% of the  Fund's  total  assets in blue chip  stocks of
    foreign issuers or in American Depositary Receipts (ADRs), Global Depositary
    Receipts  (GDRs),  or similar  forms of ownership  interest in securities of
    foreign  issuers  that are traded on U.S.  securities  exchanges  or in U.S.
    over-the-counter markets.

[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 are the decisions to buy and sell stocks made?

 A  We generally invest in companies that are, or have the prospect of becoming,
    dominant  in their  industry.  We expect  the sales  and  earnings  of these
    companies to grow faster than those of their industry  peers.  We consider a
    number of factors such as:

                                       12
<PAGE>
    o  a company's strategic position in its industry,
    o  sales and earnings growth,
    o  cash flow,
    o  book value, and
    o  dividend yield.

    We will sell a security when we perceive that our original investment thesis
    no longer holds.

For  additional  information  about other  securities in which we may invest the
Fund's assets, see APPENDIX A on page 26.

USING MUTUAL FUNDS IN AN
ASSET ALLOCATION PROGRAM

I. The Idea Behind Asset Allocation

If you have money to invest and hear that stocks may be a good investment, is it
a wise idea to use your entire savings to buy one stock? Most people wouldn't --
it would be fortunate if it works, but this strategy holds a great deal of risk.
Surprising  news could be reported  tomorrow on your stock,  and its price could
soar or plummet.

Careful  investors  understand  this  concept  of risk and  lower  that  risk by
diversifying their holdings among a number of securities.  That way bad news for
one security may be counterbalanced by good news regarding other securities. But
there is still a  question  of risk  here.  History  tells  us that  stocks  are
generally more volatile than bonds and that  long-term  bonds are generally more
volatile  than  short-term  bonds.  History  also  tells us that over many years
investments  having  higher risks tend to have higher  returns than  investments
that  carry  lower  risks.  From  these  observations  comes  the  idea of asset
allocation.

Asset  allocation is a concept that  involves  dividing your money among several
different  types of investments -- for example,  stocks,  bonds,  and short-term
investments  such as money market  instruments  -- and keeping  that  allocation
until your objectives or the financial markets  significantly  change.  That way
you're not pinning  all your  financial  success on the  fortunes of one kind of
investment.  Money spread across  different  investment  categories can help you
reduce market risk and likely will provide more stability to your total return.

Asset  allocation  can work because  different  kinds of  investments  generally
follow  different  up-and-down  cycles.  With a variety of  investments  in your
portfolio, some are probably doing well, even when others are struggling.

II. Using Asset  Allocation in an Investment  Program

Most investors  understand the concept of diversification,  but asset allocation
goes beyond  diversifying your portfolio;  it's a much more active process.  You
must evaluate your  lifestyle,  finances,  circumstances,  long- and  short-term
financial  goals,  and tolerance for investment  risk.  Once you have structured
your  allocation,  you'll need to review it regularly since your objectives will
change over time. Even though we do not charge sales loads or  commissions,  our
member service representatives are always available to assist you in structuring
and reviewing your investment portfolio.

III. USAA's Series of Asset Strategy Funds

USAA's series of asset allocation  funds, our Asset Strategy Funds, are designed
for the long-term  investor and are in line with our  investment  philosophy for
investors, specifically "buy and hold for the long-term," and "don't try to time
the market." As shown below,  each of USAA's  Asset  Strategy  Funds has its own
different mix of assets and objectives.

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]

    USAA and its  affiliated  companies  may  open an  account  through  payroll
    deduction for as little as $25 per pay period with no initial investment.

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 your
cost basis in the shares and the price received upon redemption.

                                       19

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

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   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 $900, 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 20.

                                       21

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).

                                   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.  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 Trustees. 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 Trustees.

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  quarterly.  Any net capital gain
distribution  usually occurs within 60 days of the May 31 fiscal year end, which
would be  somewhere  around  the end of  July.  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

                                       22
<PAGE>
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.  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.

Distributions to shareholders  derived from tax-exempt  interest received by the
Fund will be excluded from a  shareholder's  gross income for federal income tax
purposes, provided the Fund meets certain requirements.

IN CERTAIN INSTANCES, TAX-EXEMPT INTEREST HAS TAX IMPLICATIONS.

For corporations,  all tax-exempt interest will be considered in calculating the
alternative minimum tax as part of the adjusted current earnings.

Distributions of tax-exempt  income are considered in computing the portion,  if
any, of social security and railroad retirement benefits subject to federal and,
in some cases, state taxes.

                                       23
<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, including
the portion of the dividends  constituting  interest on private  activity bonds;
and the percentage and source,  on a  state-by-state  basis,  of interest income
earned,  if any,  on the  tax-exempt  securities  held by the  Fund  during  the
preceding year.

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.

<PAGE>
                                   APPENDIX A

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

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.

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.

PUT BONDS

We may invest the Fund's assets in tax-exempt  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).

o   Such  securities will normally trade as if maturity is the earlier put date,
    even though stated maturity is longer. Under the Fund's portfolio allocation
    procedure,  maturity for put bonds is deemed to be the date on which the put
    becomes exercisable.

ZERO COUPON BONDS

We may invest the Fund's assets in zero coupon bonds.

o   A zero coupon bond is a security  that is sold at a deep  discount  from its
    face value,  makes no periodic  interest  payments,  and is redeemed at face
    value when it matures.

o   The lump sum payment at maturity  increases the price volatility of the zero
    coupon  bond to  changes in  interest  rates  when  compared  to a bond that
    distributes a semiannual coupon payment.

o   In  calculating  its  dividend,   the  Fund  records  as  income  the  daily
    amortization of the purchase discount.

                                       26
<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.

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.

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.

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

The Fund's investment  objective is to seek high total return, with reduced risk
over time,  through an asset  allocation  strategy that seeks a  combination  of
long-term growth of capital and current income.  Using preset target ranges,  we
will  invest the Fund's  assets in a  combination  of stocks on the one hand and
bonds and money market instruments on the other.

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,  credit risk,  and
interest rate risk.

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

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 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.

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

                                       2
<PAGE>
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.

    o  You are seeking a fund that will  diversify  your holdings among a number
       of stocks and bonds.

    o  You are seeking an appropriate  investment  for an IRA,  through a 401(k)

COULD THE VALUE OF YOUR INVESTMENT
IN THIS FUND FLUCTUATE?

with the changing market values of the investments in the Fund.

FUND INVESTMENTS

Principal Investment Strategies and Risks

 Q  What is the Fund's principal investment strategy?

 A  The Fund's principal strategy is to provide a diversified investment program
    within one mutual  fund by  allocating  its assets in each of the  following
    investment categories according to the following targeted ranges. Securities
    are classified by category at the time of purchase.

[PIE CHART]
                                 PERCENTAGE TARGET RANGE
    INVESTMENT CATEGORY               OF NET ASSETS

    STOCKS                                50-70%
    BONDS                                 30-50%
    MONEY MARKET INSTRUMENTS               0-10%

The ranges  allow for a variance  within each  investment  category.  The Fund's
Board of  Trustees  may revise the target  ranges  upon 60 days'  prior  written
notice to  shareholders.  However,  we may go outside  the ranges on

                                       6
<PAGE>
a temporary  defensive  basis  without  shareholder  notification   whenever  we
believe it is in the best interest of the Fund and its shareholders.

 Q  Why are stocks and bonds mixed in the same Fund?

 A  From time to time the stock and bond markets may fluctuate  independently of
    each other.  In other  words,  a decline in the stock market may, in certain
    instances,  be  offset by a rise in the bond  market,  or vice  versa.  As a
    result,  the Fund, with its mix of stocks and bonds, is expected in the long
    run to entail less market risk (and  potentially  less return) than a mutual
    fund investing exclusively in stocks.

 Q  Why were these investment categories and target ranges selected?

 A  The  investment  categories  and  target  ranges  were  selected  to provide
    investors  with a diversified  investment  in a single  mutual fund.  Stocks
    provide the  potential for  long-term  capital  growth while bonds provide a
    high current return.  Money market instruments provide a means for temporary
    investment of cash balances arising in the normal course of business.

    However,  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.

 Q  What  actions  are taken to keep the  Fund's  asset  allocations  within the
    target ranges?

 A  If  market  action  causes  the  actual  assets  of the  Fund in one or more
    investment  categories to move outside the ranges,  we will make adjustments
    to rebalance the portfolio.  In general,  we will rebalance the portfolio at
    least once during each quarter. In rebalancing the Fund's portfolio, we will
    buy or sell securities to return the actual  allocation of the Fund's assets
    to within its target ranges. For example, the Fund's portfolio could begin a
    quarter with its assets  allocated  65% in stocks,  30% in bonds,  and 5% in
    money market  instruments.  During the quarter,  due to market returns,  the
    Fund's  portfolio  could hold 75% in stocks,  20% in bonds,  and 5% in money
    market instruments.  In this case, we would sell stocks and use the proceeds
    to buy  bonds to bring the  stocks  and bonds  back to within  their  target
    ranges.

                                       7
<PAGE>
[CAUTION LIGHT]
REBALANCING RISK. In purchasing and selling securities in order to rebalance its
portfolio, the Fund will pay more in brokerage commissions than it would without
a rebalancing  policy.  As a result of the need to rebalance,  the Fund also has
less  flexibility  in the timing of purchases  and sales of  securities  than it
would  otherwise.  While we will attempt to minimize  any adverse  impact to the
Fund or its shareholders, the Fund may have a higher proportion of capital gains
and a lower return than a fund that does not have a rebalancing policy.

Stocks

 Q  What types of stocks are included in the Fund's portfolio?

 A  We will  invest  this  portion  of the  Fund's  portfolio  significantly  in
    domestic common stocks. To a much lesser extent, we may include some foreign
    stocks and real estate investment trusts (REITs).

[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 are the decisions to buy and sell stocks made?

 A  We generally invest in companies that are, or have the prospect of becoming,
    dominant  in their  industry.  We expect  the sales  and  earnings  of these
    companies to grow faster than those of their industry  peers.  We consider a
    number of factors such as:

    o  a company's strategic position in its industry,
    o  sales and earnings growth,
    o  cash flow,
    o  book value, and
    o  dividend yield.

    We will sell a security when we perceive that our original investment thesis
    no longer holds.

Bonds and Money Market Instruments

 Q  What types of bonds are included in the Fund's portfolio?

 A  Bonds must be  investment  grade at the time of purchase and may include any
    of the following:

    o  obligations of the U.S. government, its agencies and instrumentalities;
    o  mortgage-backed securities;
    o  asset-backed securities;
    o  corporate debt securities, such as notes and bonds;
    o  debt securities of real estate investment trusts;
    o  obligations  of state  and local  governments  and  their  agencies  and
       instrumentalities;
    o  Eurodollar obligations;
    o  Yankee obligations; and
    o  other debt securities.

    For a further description of these securities, see APPENDIX A on page 25.

[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.

 Q  What are considered investment-grade securities?

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

                                       9

   ==========================================================================
     Moody's Investors                                    At least MIG 4
      Services, Inc.              At least Baa            or VMIG 4
   --------------------------------------------------------------------------
     Standard & Poor's                                    At least A-3
      Ratings Group               At least BBB            or SP-2
   --------------------------------------------------------------------------
     Fitch IBCA, Inc.             At least BBB            At least F-3
   --------------------------------------------------------------------------
     Duff and Phelps              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 Funds
    Statement of Additional Information.

[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.

 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 Trustees.

                                       10
<PAGE>
 Q  How are the decisions to buy and sell bonds made?

 A  We buy bonds that represent value in 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 security is available.

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

 A  The  money  market   instruments   included  in  the  Fund's  portfolio  are
    investment-grade,   U.S.   dollar-denominated   debt  securities  that  have
    remaining  maturities  of one year or less.  They may carry  either fixed or
    variable interest rates and may include any of the following:

    o  obligations of the U.S. government, its agencies and instrumentalities;
    o  repurchase agreements collateralized by the same;
    o  commercial paper or other short-term corporate obligations;
    o  certificates of deposit;
    o  bankers' acceptances; and
    o  other suitable obligations.

For  additional  information  about other  securities in which we may invest the
Fund's assets, see APPENDIX A on page 25.

USING MUTUAL FUNDS IN AN
ASSET ALLOCATION PROGRAM

I. The Idea Behind Asset Allocation

If you have money to invest and hear that stocks may be a good investment, is it
a wise idea to use your entire savings to buy one stock? Most people wouldn't --
it would be fortunate if it works, but this strategy holds a great deal of risk.
Surprising  news could be reported  tomorrow on your stock,  and its price could
soar or plummet.

Careful  investors  understand  this  concept  of risk and  lower  that  risk by
diversifying their holdings among a number of securities.  That way bad news for
one security may be counterbalanced by good news regarding other securities. But
there is still a  question  of risk  here.  History  tells  us that  stocks  are
generally more volatile than bonds and that  long-term  bonds are generally more
volatile  than  short-term  bonds.  History  also  tells us that over many years
investments  having  higher risks tend to have higher  returns than  investments
that  carry  lower  risks.  From  these  observations  comes  the  idea of asset
allocation.

Asset  allocation is a concept that  involves  dividing your money among several
different  types of investments -- for example,  stocks,  bonds,  and short-term
investments  such as money market  instruments  -- and keeping  that  allocation
until your objectives or the financial markets  significantly  change.  That way
you're not pinning  all your  financial  success on the  fortunes of one kind of
investment.  Money spread across  different  investment  categories can help you
reduce market risk and likely will provide more stability to your total return.

Asset  allocation  can work because  different  kinds of  investments  generally
follow  different  up-and-down  cycles.  With a variety of  investments  in your
portfolio, some are probably doing well, even when others are struggling.

                                       13
<PAGE>
II. Using Asset Allocation in an Investment Program

Most investors  understand the concept of diversification,  but asset allocation
goes beyond  diversifying your portfolio;  it's a much more active process.  You
must evaluate your  lifestyle,  finances,  circumstances,  long- and  short-term
financial  goals,  and tolerance for investment  risk.  Once you have structured
your  allocation,  you'll need to review it regularly since your objectives will
change over time. Even though we do not charge sales loads or  commissions,  our
member service representatives are always available to assist you in structuring
and reviewing your investment portfolio.

III. USAA's Series of Asset Strategy Funds

USAA's series of asset allocation  funds, our Asset Strategy Funds, are designed
for the long-term  investor and are in line with our  investment  philosophy for
investors, specifically "buy and hold for the long-term," and "don't try to time
the market." As shown below,  each of USAA's  Asset  Strategy  Funds has its own
different mix of assets and objectives.

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

                                       15
<PAGE>
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

which will be deducted from the amount of the purchase.

Redemption of Shares

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 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.

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 18.

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).

                                   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.

                                       20
<PAGE>
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 Trustees,  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 Trustees. 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 Trustees.

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  quarterly.  Any net capital gain
distribution  usually occurs within 60 days of the May 31 fiscal year end, which
would be  somewhere  around  the end of  July.  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.

                                       21

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 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 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 the 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:

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.

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.

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.

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.

                                       25
<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.

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

                                       26
<PAGE>
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.

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 Trustees 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.

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.

Prospectus.

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

The Fund has an  objective of capital  appreciation.  We will attempt to achieve
this objective by investing the Fund's assets primarily in equity  securities of
emerging market companies.

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 the risks of
foreign investing.

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

o   Foreign investing risk involves the possibility that the Fund's  investments
    in  foreign   stock  will  decrease   because  of  currency   exchange  rate
    fluctuations,  increased price volatility,  uncertain political  conditions,
    and other factors.

Those risks are particularly heightened in this Fund due to the fact that within
the universe of foreign investing,  investments in emerging market countries are
most volatile.  Emerging market countries are less diverse and mature than other
countries and tend to be  politically  less stable.  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 are looking for an investment  in foreign  securities to balance your
       domestic securities portfolio.
    o  You are willing to give up current income for long-term growth.
    o  You are willing to accept very high risk.
    o  You are seeking an appropriate  investment  for an IRA,  through a 401(k)
       plan or 403(b) plan, or other tax-sheltered account.

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

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

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.  Because the
risks are higher in emerging markets than developed international markets or the
United States,  the Fund is expected to be significantly  more volatile than the
average equity mutual fund.

The bar chart,  shown on the next page,  illustrates  the Fund's  volatility and
performance from year to year over the life of the Fund.

Total Return

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 emerging  market  companies.  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.

[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  What is an emerging market company?

 A  An issuer is an emerging market company if:

    o  it is organized  under the laws of an emerging market country (as defined
       below);

    o  the  principal  trading  market  for its stock is in an  emerging  market
       country; or

    o  at least 50% of its  revenues  or profits  are  derived  from  operations
       within  emerging  market  countries  or at least  50% of its  assets  are
       located within emerging market countries.

                                       6
<PAGE>
 Q  What countries are considered as emerging markets?

 A  For our purposes,  emerging market  countries are all countries of the world
    excluding the following, which are referred to as developed countries:

    ASIA: Australia, Japan, New Zealand

    AMERICAS: Canada, the United States

    EUROPE:  Austria,  Belgium,  Denmark,  Finland,  France,  Germany,  Holland,
             Ireland, Italy, Luxembourg, Norway, Spain, Sweden, Switzerland, the
             United Kingdom

 Q  What are the  characteristics  of the  economic  and  political  systems  of
    emerging market countries?

 A  The economic  and  political  systems of emerging  market  countries  can be
    described as possessing two or more of the following characteristics:

    o  The   countries   in  which  these   stock   markets  are  found  have  a
       less-developed economy than the developed countries.

    o  Economies of these countries are likely to be undergoing  rapid growth or
       some major structural change, such as a change in economic systems, rapid
       development  of  an  industrial  or  value-added   economic  sector,   or
       attainment of  significantly  better terms of trade for primary goods, to
       name a few examples.

    o  Sustainable economic growth rates are higher, or potentially higher, than
       developed countries.

    o  Economies of these countries may be benefitting  from the rapid growth of
       neighboring countries and/or may be significantly influenced by growth of
       demand in the developed markets.

    o  Personal  income levels and consumption are generally lower than those in
       developed countries, but may be growing at a faster rate.

    o  The  political  system is likely to be, or appear to be, in greater  flux
       than the developed countries listed above.

                                       7
<PAGE>
 Q  In what emerging market countries does the Fund intend to invest?

 A  Some of the  countries in which we expect to invest or may invest the Fund's
    assets include, but are not limited to:

    ASIA: China,  Hong  Kong,  India,  Indonesia,  Korea,  Malaysia,   Pakistan,
          Philippines, Singapore, Taiwan, Thailand

    AMERICAS: Argentina, Brazil, Chile, Columbia, Mexico, Peru, Venezuela

    AFRICA/MIDDLE EAST: Egypt, Ghana, Israel, Morocco, South Africa, Turkey

    EUROPE/OTHER: Croatia, Czech Republic,  Greece, Hungary,  Poland,  Portugal,
                  Russia, Slovakia

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

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  Will the Fund's assets be invested in any other securities?

 A  We may  invest  the  remainder  of the  Fund's  assets in  investment-grade,
    short-term debt instruments having the following characteristics:

    o  remaining  maturities  of less than one year  that  have  been  issued or
       guaranteed as to both  principal  and interest by the U.S.  government or
       its agencies or instrumentalities, and

    o  repurchase agreements collateralized by such securities.

    The Fund may also invest part of its cash position in  short-term  sovereign
    debt securities of emerging market  countries for the purpose of obtaining a
    higher  yield.  Additionally,  we may invest the Fund's  assets in stocks of
    selected  issuers  that  have  favorable  growth  prospects,  but may not be
    organized or otherwise situated in emerging markets.

                                       8
<PAGE>
    We may also invest the Fund's  assets in public and private  sector debt and
    fixed income  instruments of emerging market issuers,  including Brady Bonds
    of selected  countries,  which we believe have the potential for significant
    capital  appreciation (due, for example,  to our assessment of prospects for
    the issuer or its  domicile  country),  without  regard to any  interest  or
    dividend  yields  payable   pursuant  to  such   securities.   These  latter
    investments may be considered to be speculative in nature.

    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.

 Q  Are there any  restrictions  as to the types of  business or  operations  of
    companies in which the Fund's assets may be invested?

 A  No, there are no  restrictions  except that we may not invest 25% or more of
    the Fund's  total assets in one  industry.  The Fund's  investments  will be
    diversified in four or more countries.

    We believe that attractive  investment  opportunities exist in many emerging
    markets.  While  investing a person's  assets solely in an emerging  markets
    fund may not be suitable,  for those  willing to accept  higher  volatility,
    including the Emerging  Markets Fund in a  well-diversified  portfolio could
    significantly   enhance  returns.   The  Fund  combines  the  advantages  of
    diversified   investment  in  emerging  markets  with  the  convenience  and
    liquidity of a mutual fund based in the United States.

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

 A  We review countries and regions for economic and political stability as well
    as future  prospects.  Then we  research  individual  companies  looking for
    favorable valuations,  growth prospects, quality of management, and industry
    outlook.  Securities  are sold if we believe they are  overvalued  or if the
    political environment significantly deteriorates.

For  additional  information  about other  securities in which we may invest the
Fund's assets, see APPENDIX B on page 24.

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

brokerage  orders) and its  business  affairs,  subject to the  authority of and
supervision by the Fund's Board of Trustees.  For our services, the Fund pays us
an annual fee. This fee was computed and paid at one percent (1%) of average net
assets for the fiscal year ended May 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

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

                                       10
<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 diversify internationally. You could divide your
investments among the Emerging  Markets,  Gold,  International,  or World Growth
Funds and  holdings  in  domestic  funds.  This would give you  exposure  to the
opportunities of investments in many foreign  countries and to currency changes.
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 C under asset  allocation on page 26. 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 help you craft a
portfolio to meet your needs. Refer to APPENDIX C on page 26 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

    redemptions,  review account  activity,  check balances,  and more. To place
    orders by Internet, an ESA and EFT Buy/Sell authorization must be on file.

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.

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

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   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 $900, 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 15.

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).

                                   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  supervision  of the Fund's
Board of Trustees,  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 Trustees. Securities that cannot
be valued by these methods, and all other assets, are valued

                                       17
<PAGE>
in good faith at fair value using methods we have  determined  under the general
supervision of the Fund's Board of Trustees.

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 May 31 fiscal year end, which
would be  somewhere  around  the end of  July.  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.

Taxes

FEDERAL

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.

FOREIGN

The Fund may be subject to foreign  withholding or other taxes. If more than 50%
of the  value of the  Fund's  total  assets  at the  close of any  taxable  year
consists of  securities of foreign  corporations,  the Fund may file an election
with the Internal  Revenue Service (the Foreign  Election) that would permit you
to take a credit (or a deduction) for foreign income

                                       18
<PAGE>
taxes paid by the Fund.  If the Foreign  Election is made,  you would include in
your gross income both dividends received from the Fund and foreign income taxes
paid by the Fund. As a shareholder  of the Fund,  you would be entitled to treat
the foreign income taxes  withheld as a credit against your U.S.  federal income
taxes,  subject to the limitations  set forth in the Internal  Revenue Code with
respect to the foreign tax credit  generally.  Alternatively,  you could,  if it
were to your  advantage,  treat the foreign income taxes withheld as an itemized
deduction in computing taxable income rather than as a tax credit.  You will not
be  entitled  to a foreign  tax  credit  for taxes  paid to  certain  countries;
however, if the Fund otherwise  qualifies for the Foreign Election,  a deduction
for such taxes will be available to  shareholders of the Fund. It is anticipated
that the Fund will make the Foreign Election.

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 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 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 the 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.

Moody's Corporate Ratings

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.

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.

S&P Corporate Ratings

BBB  An obligation rated "BBB" exhibits ADEQUATE protection parameters. 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 that 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.

                                       22
<PAGE>
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 "CC" 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.

     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.

A description of ratings "A" or better  assigned to debt  obligations by Moody's
and S&P is included in APPENDIX A of the Statement of Additional Information.

<PAGE>
                                   APPENDIX B

The  following are  descriptions  of certain types of securities in which we may
invest the Fund's assets:

Forward Currency Contracts

The Fund 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,  the Fund 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 the security until settlement.

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.

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.

Brady Bonds and Emerging Market Debt

We may invest the Fund's  assets in Brady  Bonds and public and  private  sector
debt and fixed income  instruments of emerging market  issuers.  Brady Bonds are
securities  created  through a  restructuring  plan  introduced  by former  U.S.
Treasury  Secretary  Nicholas  Brady.  The Brady  Plan made  provisions  whereby
existing  commercial bank loans to both public and private  entities in selected
developing  countries  are  exchanged  for  Brady  Bonds.  These  bonds  may  be
denominated in other  currencies,  but are usually  denominated in U.S. dollars.
Brady Bonds are actively traded in over-the-counter  markets. As the markets for
these  securities  have from time to time been  subject to  disruption,  we will
monitor,  on a continuous basis, the liquidity of Brady Bonds held in the Fund's
portfolio.

                                       24
<PAGE>
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.

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.

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.

Prospectus.

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

The Fund has an objective to seek long-term capital  appreciation and to protect
the  purchasing  power of your capital  against  inflation.  Current income is a
secondary objective.  We will attempt to achieve these objectives by investing a
great majority of the Fund's assets in equity securities of domestic and foreign
gold exploration, mining, or processing companies.

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 6 for more information.

MAIN RISKS OF INVESTING IN THIS FUND

The primary  risks of investing  in this Fund are the  increased  volatility  of
mining stocks, market risk, and the risks of foreign investing.

o   GOLD MINING RISK involves additional risk because of gold's price volatility
    and the increased  impact such volatility has on the  profitability  of gold
    mining companies.

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

o   FOREIGN INVESTING RISK involves the possibility that the Fund's  investments
    in  foreign   stock  will  decrease   because  of  currency   exchange  rate
    fluctuations,  increased price volatility,  uncertain political  conditions,
    and other factors.

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.

IS THIS FUND FOR YOU?

    o  You are willing to give up current income for long-term growth.
    o  You are willing to accept very high risk.
    o  You are seeking an appropriate  investment  for an IRA,  through a 401(k)
       plan or 403(b) plan, or other tax-sheltered account.

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

    o  You need an investment that provides steady income.
    o  You need an investment that provides tax-free income.
    o  You are unwilling to take very high risk for long-term growth.

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. Because the Fund
will invest in companies  principally  engaged in gold  exploration,  mining, or
processing,  the Fund  may be  subject  to  greater  risks  and  greater  market
fluctuations  than other funds with a portfolio  of  securities  representing  a
broader range of industries.

The bar chart,  shown on the next page,  illustrates  the Fund's  volatility and
performance from year to year for 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 to  investment at least 80% of its assets
    during   normal  market   conditions  in  equity   securities  of  companies
    principally engaged in gold exploration,  mining, or processing.  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.

    Since the  majority  of the Fund's  assets  will be  invested  in  companies
    principally engaged in gold exploration, mining, or processing, the Fund may
    be subject to greater risks and greater market fluctuations than other funds
    with a portfolio of  securities  representing  a broader range of investment
    objectives.

[CAUTION LIGHT]
VOLATILITY OF GOLD MINING SECURITIES.  Gold mining securities involve additional
risk because of gold's price volatility and the increased impact such volatility
has on the  profitability of gold mining  companies.  However,  since the market
action of such  securities  has  tended  to move  independently  of the  broader
financial markets,  the addition of gold mining securities to your portfolio may
reduce overall fluctuations in portfolio value.

 Q  Will the Fund's assets be invested in any other securities?

 A  We may invest the  remainder of the Fund's  assets in equity  securities  of
    companies similarly engaged in other precious

                                       6
<PAGE>
    metals and minerals and in  investment-grade,  short-term  debt  instruments
    having the following characteristics:

    o  maturities  of less than one year that have been issued or  guaranteed as
       to both principal and interest by the U.S.  government or its agencies or
       instrumentalities, and

    o  repurchase agreements collateralized by such securities.

    If we believe the outlook for gold is unattractive, as a temporary defensive
    measure, we may invest up to 100% of the Fund's assets in  investment-grade,
    short-term debt instruments,  which 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  Will the Fund's assets be invested in foreign securities?

 A  We may invest the Fund's  assets in foreign  securities  purchased in either
    foreign or U.S. markets.

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

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.

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

 A  We look for well-managed and prudently financed low-cost producers with good
    production or reserve growth  potential that sell at a reasonable  valuation
    on a risk-adjusted  basis. We will sell these securities when they no longer
    meet these criteria.

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 Trustees.  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 May 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
Trustees  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.

For example, assume you wish to diversify internationally. You could divide your
investments  between the Gold and  International  Funds and holdings in domestic
funds.  This would give you exposure to the opportunities of investments in many
foreign  countries  and to  currency  changes.  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 22. 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 help you craft a
portfolio to meet your needs. Refer to APPENDIX B on page 22 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

                                       10

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

Redemption of Shares

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

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

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   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 $900, 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.

                                       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).

                                   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  supervision  of the Fund's
Board of Trustees,  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 Trustees. Securities that cannot
be valued by these methods, and all other assets, are valued in good

                                       15
<PAGE>
faith  at  fair  value  using  methods  we have  determined  under  the  general
supervision of the Fund's Board of Trustees.

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 May 31 fiscal year end, which
would be  somewhere  around  the end of  July.  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.

Taxes

FEDERAL

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.

FOREIGN

The Fund may be subject to foreign  withholding or other taxes. If more than 50%
of the  value of the  Fund's  total  assets  at the  close of any  taxable  year
consists of  securities of foreign  corporations,  the Fund may file an election
with the Internal  Revenue Service (the Foreign  Election) that would permit you
to take a credit (or a deduction)  for foreign income taxes paid by the Fund. If
the  Foreign  Election  is made,  you would  include in your gross  income  both
dividends received from the Fund and foreign income taxes paid

                                       16
<PAGE>
by the Fund.  As a shareholder  of the Fund,  you would be entitled to treat the
foreign  income  taxes  withheld as a credit  against your U.S.  federal  income
taxes,  subject to the limitations  set forth in the Internal  Revenue Code with
respect to the foreign tax credit  generally.  Alternatively,  you could,  if it
were to your  advantage,  treat the foreign income taxes withheld as an itemized
deduction in computing taxable income rather than as a tax credit.  You will not
be  entitled  to a foreign  tax  credit  for taxes  paid to  certain  countries;
however, if the Fund otherwise  qualifies for the Foreign Election,  a deduction
for such taxes will be available to  shareholders of the Fund. It is anticipated
that the Fund will make the Foreign Election.

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 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 the 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

                                   APPENDIX A

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

FORWARD CURRENCY CONTRACTS

The Fund 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,  the Fund 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 the security until settlement.

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.

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.

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.

                                       20
<PAGE>
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.

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.

  If  you  would  like  more   information   about  the  Fund,  you  may  call
  1-800-531-8181  to request a free copy of the Fund's Statement of Additional
  Information  (SAI),  Annual or Semiannual  Report, or to ask other questions
  about the Fund.  The SAI has been filed  with the  Securities  and  Exchange
  Commission  (SEC) and is  legally a part of the  Prospectus.  In the  Fund's
  Annual  Report,  you will find a  discussion  of the market  conditions  and
  investment  strategies that  significantly  affected the Fund's  performance
  during the last fiscal year.

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 has an  objective  of capital  appreciation  with  current  income as a
secondary  objective.  We will attempt to achieve these  objectives by investing
the  great  majority  of the  Fund's  assets  in equity  securities  of  foreign
companies.

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 6 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
foreign investing.

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

o   FOREIGN INVESTING RISK involves the possibility that the Fund's  investments
    in  foreign   stock  will  decrease   because  of  currency   exchange  rate
    fluctuations,  increased price volatility,  uncertain political  conditions,
    and other factors.

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 are looking for long-term growth.
    o  You are willing to accept moderate to high risk.
    o  You are seeking an appropriate  investment  for an IRA,  through a 401(k)
       plan or 403(b) plan, or other tax-sheltered account.
    o  You are looking for an investment  in foreign  securities to balance your
       domestic securities portfolio.

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 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.  Because the
risks in  international  markets as a whole tend to be higher than in the United
States,  the Fund is expected  to be more  volatile  than the  average  domestic
equity mutual fund.

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

    THE FUND'S TOTAL RETURN FOR THE  SIX-MONTH  PERIOD ENDED JUNE 30, 1999,
    WAS 6.47%.

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 foreign  companies.  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.

[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  What is considered to be a "foreign company?"

 A  A foreign company is one organized under the laws of a foreign country,  and
    it must also have one of the following additional characteristics:

    o  the principal trading market for the stock is in a foreign country;

    o  at least 50% of its  revenues  or profits  are  derived  from  operations
       within foreign countries; or

    o  at least 50% of its assets are located within foreign countries.

[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

                                       6
<PAGE>

limits;   different   accounting,   reporting,   and  disclosure   requirements;
difficulties in obtaining legal judgments;  and foreign withholding taxes. Three
forms of foreign  investing risk are emerging markets risk,  political risk, and
euro conversion risk.

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.

o   EURO CONVERSION  RISK. On January 1, 1999,  countries  participating  in the
    European  Monetary  Union  began  converting  their  currencies  into  a new
    currency  unit  called  the Euro.  The  conversion  to the Euro,  which will
    continue in stages  through  2002,  is  expected  to reshape  the  financial
    markets, banking systems, and monetary policies in Europe and other parts of
    the  world  and could  adversely  affect  the  Fund's  investments  in these
    markets.  In addition,  a failure of the clearing and settlement  systems in
    these markets to handle the Euro conversion could adversely affect the Fund.

 Q  Will the Fund's assets be invested in any other securities?

 A  We may invest the  remainder of the Fund's  assets in equity  securities  of
    companies  that meet any of the criteria as described in the definition of a
    foreign company and in investment-grade,  short-term debt instruments having
    the following characteristics:

    o  remaining  maturities  of less than one year  that  have  been  issued or
       guaranteed as to both  principal  and interest by the U.S.  government or
       its agencies or instrumentalities, or

    o  repurchase agreements collateralized by such securities.

    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.

 Q  Are there any  restrictions  as to the types of  businesses or operations of
    companies in which the Fund's assets may be invested?

 A  No, there are no restrictions except that we may not invest more than 25% of
    the Fund's  total assets in one  industry.  The Fund's  investments  will be
    diversified in at least four or more countries.

                                       7
<PAGE>
    We believe the Fund combines the  advantages  of  investment in  diversified
    international  markets with the  convenience  and liquidity of a mutual fund
    based in the United States.

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

 A  We review countries and regions for economic and political stability as well
    as future  prospects.  Then we  research  individual  companies  looking for
    favorable valuations,  growth prospects, quality of management, and industry
    outlook.  Securities  are sold if we believe they are  overvalued  or if the
    economic or political outlook significantly deteriorates.

For  additional  information  about other  securities in which we may invest the
Fund's assets, see APPENDIX A on page 21.

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.

                                       9
<PAGE>
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 diversify internationally. You could divide your
investments among the Emerging  Markets,  Gold,  International,  or World Growth
Funds and  holdings  in  domestic  funds.  This would give you  exposure  to the
opportunities of investments in many foreign  countries and to currency changes.
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.

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 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

                                       10
<PAGE>
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
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 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.

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,

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

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   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 $900, 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 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).

Share Price Calculation

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  supervision  of the Fund's
Board of Trustees,  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 Trustees. 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 Trustees.

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

The Fund pays net  investment  income  dividends  yearly.  Any net capital  gain
distribution  usually occurs within 60 days of the May 31 fiscal year end, which
would be  somewhere  around  the end of  July.  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.

Taxes

FEDERAL

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.

FOREIGN

The Fund may be subject to foreign  withholding or other taxes. If more than 50%
of the  value of the  Fund's  total  assets  at the  close of any  taxable  year
consists of  securities of foreign  corporations,  the Fund may file an election
with the Internal  Revenue Service (the Foreign  Election) that would permit you
to take a credit (or a deduction)  for foreign income taxes paid by the Fund. If
the  Foreign  Election  is made,  you would  include in your gross  income  both
dividends received from the Fund and foreign income taxes paid by the Fund. As a
shareholder of the Fund, you would be entitled to treat the foreign income taxes
withheld as a credit  against your U.S.  federal  income  taxes,  subject to the
limitations set forth in the

                                       17
<PAGE>
Internal  Revenue  Code  with  respect  to the  foreign  tax  credit  generally.
Alternatively, you could, if it were to your advantage, treat the foreign income
taxes withheld as an itemized  deduction in computing taxable income rather than
as a tax credit. You will not be entitled to a foreign tax credit for taxes paid
to certain countries;  however,  if the Fund otherwise qualifies for the Foreign
Election,  a deduction for such taxes will be available to  shareholders  of the
Fund. It is anticipated that the Fund will make the Foreign Election.

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 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
represent the rate that an investor would have earned (or lost) on an investment
in the 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

                                   APPENDIX A

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

FORWARD CURRENCY CONTRACTS

The Fund 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,  the Fund 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 the security until settlement.

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.

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.

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.

                                       21
<PAGE>
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.

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.

Prospectus.

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

The Fund has an  objective of capital  appreciation.  We will attempt to achieve
this  objective by investing  the Fund's  assets  mostly in a mix of foreign and
domestic equity 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 5 for more information.

MAIN RISKS OF INVESTING IN THIS FUND

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

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

o   FOREIGN INVESTING RISK involves the possibility that the Fund's  investments
    in  foreign   stock  will  decrease   because  of  currency   exchange  rate
    fluctuations,  increased price volatility,  uncertain political  conditions,
    and other factors.

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 looking for long-term growth.
    o  You are willing to accept moderate to high risk.
    o  You are seeking an appropriate  investment  for an IRA,  through a 401(k)
       plan or 403(b) plan, or other tax-sheltered account.

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 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. Because the Fund
invests in foreign  markets,  this Fund is expected to be more volatile than the
average equity mutual fund.

The bar chart  illustrates the Fund's  volatility and  performance  from year to
year over the life of the Fund.

Total Return

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

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

The table below shows how the Fund's  average  annual total returns for the one-

broad-based securities market index.  Remember,  historical performance does not
necessarily indicate what will happen in the future.

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 both  foreign and domestic  issuers.  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.

[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

                                       5
<PAGE>
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  Why are foreign and domestic stocks combined in the Fund's portfolio?

 A  We believe that  international  diversification  may have a balancing impact
    with regard to domestic  investments  during periods of adverse economic and
    market  conditions in the United  States.  Therefore,  the Fund combines the
    advantages of investing in a diversified  international  market and domestic
    market,  with the  convenience  and  liquidity of a mutual fund based in the
    United States.

[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;  difficulties  in  obtaining
legal judgments; and foreign withholding taxes. Three forms of foreign investing
are emerging markets risk, political risk, and euro conversion risk.

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.

o   EURO CONVERSION  RISK. On January 1, 1999,  countries  participating  in the
    European  Monetary  Union  began  converting  their  currencies  into  a new
    currency  unit  called  the Euro.  The  conversion  to the Euro,  which will
    continue in stages  through  2002,  is  expected  to reshape  the  financial
    markets, banking systems, and monetary policies in Europe and other parts of
    the  world  and could  adversely  affect  the  Fund's  investments  in these
    markets.  In addition,  a failure of the clearing and settlement  systems in
    these markets to handle the Euro conversion could adversely affect the Fund.

 Q  Will the Fund's assets be invested in any other securities?

 A  We may  invest  the  remainder  of the  Fund's  assets in  investment-grade,
    short-term debt instruments having the following characteristics:

                                       6
<PAGE>

    o  remaining  maturities  of less than one year  that  have  been  issued or
       guaranteed as to both  principal  and interest by the U.S.  government or
       its agencies or instrumentalities, or

    o  repurchase agreements collateralized by such securities.

    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.

 Q  Are there any  restrictions  as to the types of  businesses or operations of
    companies in which the Fund's assets may be invested?

 A  No, there are no restrictions except that we may not invest more than 25% of
    the Fund's total assets in one industry. Under normal market conditions, the
    Fund's investments will be diversified in at least three countries.

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

 A  We review countries and regions for economic and political stability as well
    as future  prospects.  Then we  research  individual  companies  looking for
    favorable valuations,  growth prospects, quality of management, and industry
    outlook.  Securities  are sold if we believe they are  overvalued  or if the
    economic or political outlook significantly deteriorates.

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

 A  We generally invest in companies that are, or have the prospect of becoming,
    dominant  in their  industry.  We expect  the sales  and  earnings  of these
    companies to grow faster than those of their industry  peers.  We consider a
    number of factors such as:

    o  a company's strategic position in its industry,
    o  sales and earnings growth,
    o  cash flow,
    o  book value, and
    o  dividend yield.

    We will sell a security when we perceive that our original investment thesis
    no longer holds.

For  additional  information  about other  securities in which we may invest the
Fund's assets, see APPENDIX A on page 21.

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

                                       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 diversify internationally. You could divide your
investments among the Emerging Markets, International, or World Growth Funds and
holdings in domestic funds. This would give you exposure to the opportunities of
investments in many foreign countries and to currency changes.  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 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.

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

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   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 $900, 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 14.

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  supervision  of the Fund's
Board of Trustees,  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

                                       16
<PAGE>
are valued each  business day at their  current  market value as determined by a
pricing service approved by the Fund's Board of Trustees. 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 Trustees.

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 May 31 fiscal year end, which
would be  somewhere  around  the end of  July.  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.

Taxes

FEDERAL

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.

                                       17
<PAGE>
FOREIGN

The Fund may be subject to foreign  withholding or other taxes. If more than 50%
of the  value of the  Fund's  total  assets  at the  close of any  taxable  year
consists of  securities of foreign  corporations,  the Fund may file an election
with the Internal  Revenue Service (the Foreign  Election) that would permit you
to take a credit (or a deduction)  for foreign income taxes paid by the Fund. If
the  Foreign  Election  is made,  you would  include in your gross  income  both
dividends received from the Fund and foreign income taxes paid by the Fund. As a
shareholder of the Fund, you would be entitled to treat the foreign income taxes
withheld as a credit  against your U.S.  federal  income  taxes,  subject to the
limitations  set forth in the Internal  Revenue Code with respect to the foreign
tax credit  generally.  Alternatively,  you could, if it were to your advantage,
treat the foreign  income taxes  withheld as an itemized  deduction in computing
taxable  income  rather  than as a tax  credit.  You will not be  entitled  to a
foreign  tax credit for taxes paid to certain  countries;  however,  if the Fund
otherwise qualifies for the Foreign Election, a deduction for such taxes will be
available to shareholders of the Fund. It is anticipated that the Fund will make
the Foreign Election.

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 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.

                                       18

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  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:

FORWARD CURRENCY CONTRACTS

The Fund 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,  the Fund 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 the security until settlement.

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.

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.

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.

                                       21
<PAGE>
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.

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.

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

The Fund has an objective of providing  investors a high level of current income
consistent  with  preservation  of  principal.  We will  attempt to achieve this
objective by investing the Fund's assets in securities  backed by the full faith
and credit of the U.S.  government.  Most of the Fund's investments will consist
of Government National Mortgage  Association (GNMA)  pass-through  certificates,
which represent ownership in a pool of mortgage loans or a single mortgage loan.

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
prepayment 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.

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.

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 willing to accept low to moderate risk.
    o  You are seeking an appropriate  investment  for an IRA,  through a 401(k)
       plan or 403(b) plan, or other tax-sheltered account.

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

    o  You need an investment that provides tax-free income.
    o  Your primary goal is to maximize long-term growth.

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 the GNMA Trust will
fluctuate with the changing market values of the investments in the Fund.  While
the value of the  securities in which the GNMA Trust  invests have  historically
involved  little  credit  risk,  the  market  value of these  securities  is not
guaranteed  and will  fluctuate  inversely  with changes in the general level of
interest rates.  The value of these securities will increase when interest rates
decline and decrease when interest rates rise.

The bar chart,  shown on the next page,  illustrates  the Fund's  volatility and
performance from year to year over the life of the 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 its assets primarily in
    GNMA pass-through certificates.

 Q  What are GNMA certificates?

 A  GNMA  certificates  represent  ownership  in a pool of  mortgage  loans or a
    single  mortgage  loan.  Each mortgage loan is either insured by the Federal
    Housing  Administration or guaranteed by the Veterans  Administration.  Once
    approved  by  GNMA,  each  mortgage  or pool of  mortgages  is  additionally
    guaranteed  by GNMA as to the  timely  payment  of  principal  and  interest
    (regardless of whether the  mortgagors  actually make their  payments).  The
    guarantee  represents a general obligation of the U.S. Treasury.  Therefore,
    GNMA  certificates  are  guaranteed by the full faith and credit of the U.S.
    government.

 Q  What is the credit quality of these securities?

 A  Securities  that  are  backed  by the  full  faith  and  credit  of the U.S.
    government (meaning that the payment of principal and interest is guaranteed
    by the U.S.  Treasury) are  considered to be of the highest  credit  quality
    available.

                                       6
<PAGE>
 Q  How do GNMA securities differ from conventional bonds?

 A  GNMA  securities  differ from  conventional  bonds in that principal is paid
    back to the  certificate  holders  over the life of the loan  rather than at
    maturity.  As a result,  the Fund will receive monthly scheduled payments of
    principal  and  interest.  Additionally,  the Fund may  receive  unscheduled
    principal payments, which represent prepayments on the underlying mortgages.

    Because the Fund will reinvest  these  scheduled and  unscheduled  principal
    payments  at a time when the  current  interest  rate may be higher or lower
    than the  Fund's  current  yield,  an  investment  in the Fund may not be an
    effective means of "locking in" long-term interest rates.

[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.

 Q  What is the average maturity of a GNMA certificate?

 A  GNMA certificates  evidence interest in a pool of underlying mortgages (or a
    single  mortgage),  which generally have maximum lives of either 15, 20, 30,
    or 40  years.  However,  due to both  scheduled  and  unscheduled  principal
    payments, GNMA certificates have a shorter average life and, therefore, have
    less principal volatility than a bond of comparable maturity.

    Since  the  prepayment  rates  will  vary  widely,  it is  not  possible  to
    accurately  predict the average  life of a particular  GNMA pool,  though it
    will be shorter than the stated final maturity. Because the expected average
    life  is  a  better  indicator  of  the  maturity  characteristics  of  GNMA
    certificates,  principal  volatility  and  yield may be more  comparable  to
    10-year Treasury bonds.

                                       7
<PAGE>
[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.

 Q  Will the Fund's  assets be invested  in any other  types of U.S.  government
    securities?

 A  Yes. We may invest up to 35% of the Fund's total assets in other obligations
    that have been  backed by the full faith and credit of the U.S.  government,
    including U.S.  Treasury bills,  notes and bonds,  and securities  issued by
    U.S. government agencies and instrumentalities such as, but not limited to:

    o  Federal Housing Administration,
    o  Department of Housing and Urban Development,
    o  Export-Import Bank,
    o  Farmer's Home Administration,
    o  General Services Administration,
    o  Maritime Administration,
    o  Small Business Administration, and
    o  repurchase agreements collateralized by such obligations.

    We will not invest the Fund's assets in any U.S. government  securities that
    do not carry  the full  faith and  credit  of the U.S.  government,  such as
    Fannie Mae (FNMA) or Freddie Mac (FHLMC) securities.

    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.

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

 A  We manage the Fund to generate  high total  return  with strong  emphasis on
    current income.  Since all the securities the Fund may own are backed by the
    full faith and credit of the United

                                       8
<PAGE>
    States,  credit  quality  is not a concern.  Of  particular  importance  for
    mortgage  securities is prepayment  risk. We generally try to diversify this
    risk by buying  different  kinds of mortgage  securities  which  should have
    different prepayment  characteristics.  When weighing our decision to buy or
    sell a security,  we strive to balance the value of the level of income, the
    prepayment risk, and the price volatility,  both for the individual security
    and its relationship with the rest of the portfolio.

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

FUND MANAGEMENT

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 GNMA Trust 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 22. 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 help you
craft a  portfolio  to meet your  needs.  Refer to  APPENDIX  B on page 22 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.

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 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

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

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   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 $900, 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.

                                       15

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).

                                   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.

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 Trustees. 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 Trustees.

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

Dividends and Distributions

Net investment  income is accrued daily and paid on the last business day of the
month.  Dividends shall begin accruing on shares purchased the day following the
effective date and shall continue to accrue to the effective date of redemption.
Any net capital gain  distribution  usually  occurs within 60 days of the May 31
fiscal year end, which would be somewhere  around the end of July. 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

                                       16
<PAGE>
capital gain  distribution paid by the Fund will reduce the NAV per share by the
amount  of the  distribution  on  the  ex-dividend  date.  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 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.

Regardless of the length of time you have held 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.

                                   APPENDIX A

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

REPURCHASE AGREEMENTS

We may invest the Fund's assets in repurchase  agreements  that are  exclusively
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  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.

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.

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.

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.

                                       20
<PAGE>
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.

Prospectus.

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

The Fund has an objective of providing  investors  maximum  current income while
maintaining  the  highest  degree of safety and  liquidity.  We will  attempt to
achieve  this  objective  by  investing  the  Fund's  assets in U.S.  government
securities with  maturities of 397 days or less. Most of the Fund's  investments
will be in U.S.  Treasury  bills,  notes and bonds,  and  repurchase  agreements
collateralized by these instruments.

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 interest rate risk.

o   INTEREST  RATE RISK  involves the  possibility  that the value of the Fund's
    investments in U.S.  government  securities 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.

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
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 per share net asset  value
(NAV). 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.

                                       2
<PAGE>
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.  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  Your primary goal is long-term growth.

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  Securities  and
Exchange  Commission  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 on the next page,  illustrates  the Fund's  volatility and
performance from year to year over the life of the Fund.

Total Return

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

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

    THE FUND'S TOTAL RETURN FOR THE  SIX-MONTH  PERIOD ENDED JUNE 30, 1999,
    WAS 2.23%.

During  the  periods  shown in the bar chart,  the  highest  total  return for a
quarter was 1.42% (quarter ending June 30, 1995) and the lowest total return for
a quarter was .69% (quarter ending June 30, 1993).

The table below shows the Fund's  average  annual total returns for the one- and

Yield

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

[SIDE BAR]
    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

                                       4
<PAGE>
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
4.57%.

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 exclusively in
    securities  with  maturities of 397 days or less that are backed by the full
    faith  and  credit  of  the  U.S.   government  and  repurchase   agreements
    collateralized by such securities.

 Q  What types of U.S. government  securities will the Fund's assets be invested
    in?

 A  Under normal market  conditions,  we will invest the Fund's assets primarily
    in  U.S.  Treasury  bills,  notes  and  bonds,  and  repurchase   agreements
    collateralized by such obligations.

 Q  May the Fund's  assets be  invested  in any other  types of U.S.  government
    securities?

 A  Yes. We may invest up to 35% of the Fund's total assets in other obligations
    that have been  backed by the full faith and credit of the U.S.  government,
    including   securities   issued  by  any  of  the  following   agencies  and
    instrumentalities:

    o  General Services Administration,
    o  Government National Mortgage Association,
    o  Overseas Private Investment Corporation,
    o  Rural Electrification Administration,
    o  Small Business Administration,
    o  Federal Financing Bank, and
    o  repurchase agreements collateralized by such obligations.

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

 A  While we will endeavor to maintain a constant Fund net asset value of $1 per
    share, there is no assurance that we will be able to do so.

                                       6
<PAGE>
    Remember,  the  shares  are  neither  insured  nor  guaranteed  by the  U.S.
    government. As such, the Fund carries some risk.

    There is also a risk that rising  interest rates will cause the value of the
    Fund's  securities to decline.  We attempt to minimize this interest risk by
    limiting the maturity of each security to 397 days or less and maintaining a
    dollar-weighted average portfolio maturity for the Fund of 90 days or less.

[SIDE BAR]
    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  Will any  portion  of the Fund's  dividends  be exempt  from state  personal
    income taxes?

 A  Possibly.  Under federal law, the income received from obligations issued by
    the U.S.  government  and certain of its agencies and  instrumentalities  is
    exempt from state personal income taxes.  Many states that impose a personal
    income tax permit  mutual funds to pass through this tax exemption to you as
    a shareholder of the Fund.

    We  anticipate  that some  portion  of the  dividends  paid to  shareholders
    residing  in these  states  will  qualify  for  this  exemption  from  state
    taxation.  We urge you to consult  your own tax adviser  about the status of
    distributions from the Fund in your own state and locality.

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

 A  We evaluate  securities in the marketplace  based on the Fund's objective of
    maximizing current income while maintaining the highest degree of safety and
    liquidity.  For the Treasury  Money Market Trust this process is facilitated
    by only purchasing full faith and credit obligations of the U.S.  government
    or repurchase  agreements  collateralized  by such securities.  On any given
    day, we evaluate the government securities market compared to the repurchase
    agreement market to decide which provides the most value to the shareholder.
    Furthermore,  regulations  governing money market funds limit purchases of a
    security  to a maximum  of 397 days and limit the Fund to a maximum  average
    maturity of 90 days.

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

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 Treasury Money Market Trust 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 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.

                                       9
<PAGE>
TAX ID NUMBER

Each  shareholder  named on the account must provide a social security number or
tax identification number to avoid possible withholding requirements.

EFFECTIVE DATE

When you make a purchase,  your purchase price will be the net asset value (NAV)
per share next  determined  after we receive your  request in proper  form.  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.

    orders by Internet, an ESA and EFT Buy/Sell authorization must be on file.

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 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.

of the registered account owner(s) for the account  registration.  Additionally,
all telephone  communications with you are recorded and confirmations of account

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

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   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 $900, 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).

                                   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.

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.

                                       15

Federal Taxes

This tax  information  is quite  general  and refers to the  federal  income tax
provisions in effect as of the date of this  Prospectus.  Note that the 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.

Regardless of the length of time you have held 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.

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

                                   APPENDIX A

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

REPURCHASE AGREEMENTS

We may invest the Fund's assets in repurchase  agreements  that are  exclusively
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  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.

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.

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.

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.

                             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 securities of each Fund (except  Treasury  Money Market Trust)
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 and  government  securities  are valued each  business day by a
      pricing  service  (the  Service)  approved by the Board of  Trustees.  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
      Trustees.

     The value of the Treasury  Money  Market  Trust'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  Trust  would  receive  upon the sale of the
instrument.

     The valuation of the Treasury  Money Market Trust'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 Trustees has established  procedures designed to stabilize the
Treasury  Money Market  Trust'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
Trustees  will take  such  corrective  action as it  regards  as  necessary  and
appropriate.  Such action may include,  among other options,  selling  portfolio
instruments  prior to  maturity  to the  Manager or another  party,  withholding
dividends, or establishing a NAV per share by using available market quotations.

                      CONDITIONS OF PURCHASE AND REDEMPTION

NONPAYMENT

If any order to purchase  shares is canceled due to  nonpayment  or if the Trust
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  accounts  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 Trustees may cause the redemption of an account with a balance
of less than $900,  provided that (1) the value of such account has been reduced
below the minimum  initial  investment  required in such Fund at the time of the
establishment  of the account to less than $900  entirely for reasons other than
market action, (2) the account has remained below the minimum initial investment
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 Trustees. Prompt payment will be made by mail to your
last known address.

     The Trust 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 Trust  normally  utilizes is  restricted,  or an
emergency  exists  as  determined  by the SEC so that  disposal  of the  Trust's
investments or  determination of its NAV is not reasonably  practicable,  or (3)
for such other  periods as the SEC by order may  permit  for  protection  of the
Trust's shareholders.

     For the mutual  protection  of the  investor  and the Funds,  the Trust 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  Treasury  Money  Market  Trust may request  that checks be
issued for their accounts. Checks must be written in amounts of at least $250.

     Checks issued to  shareholders  of the Treasury  Money Market Trust will be
sent only to the person in whose name the account is registered  and only to the
address of record. The checks must be manually signed by the registered owner(s)
exactly as the account is registered. For joint accounts the signature of either
or both joint  owners will be required on the check,  according  to the election
made on the signature card. 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 a check.  If the  account  balance is not

                                       3
<PAGE>
adequate  to cover the  amount of a check,  the check will be  returned  unpaid.
Because the value of the  account  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 Trust  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 Trust, 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 Trust 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

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  your  bank  or  other   financial
institution. You may also elect to have checks mailed to a designated address.

                                       4
<PAGE>
     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 Trust 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 (NOT  available  in the Growth and Tax  Strategy
Fund)

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
Investment Trust and USAA Mutual Fund, Inc.

     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 of 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.

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

The Income Strategy,  Balanced Strategy, and Growth Strategy Funds 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.  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,  except the GNMA Trust and the Treasury Money Market Trust,  may
also  purchase   restricted   securities   eligible  for  resale  to  "qualified
institutional  buyers"  pursuant to Rule 144A under the  Securities  Act of 1933
(Rule 144A Securities).  Rule 144A provides a non-exclusive safe harbor from the
registration  requirements  of the Securities Act of 1933 for resales of certain
securities to institutional investors.

MUNICIPAL LEASE OBLIGATIONS

The Income Strategy,  Balanced  Strategy,  Growth  Strategy,  and Growth and Tax
Strategy Funds may invest in municipal lease obligations,  installment  purchase
contract  obligations,  and  certificates of  participation  in such obligations
(collectively,  lease  obligations).  A lease  obligation  does not constitute a

                                       5
<PAGE>
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 Trustees has  established  guidelines  pursuant to which  Municipal
Lease Obligations,  Section 4(2) Commercial Paper and 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 Trustees: (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 Trustees.

CALCULATION OF MATURITY FOR FIXED INCOME SECURITIES

A fixed income  security's  maturity is typically  determined  on a stated final
maturity basis, although there are some exceptions to the rule.

     If the issuer of the security has committed to take advantage of a maturity
shortening device, such as a call, refunding, or redemption provision,  the date
on which the instrument will be called, refunded, or redeemed will 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. A security will be treated as having
a maturity  earlier than its stated  maturity date if the security has technical
features, such as a put or demand feature which, in the judgment of the Manager,
will  result in the  security  being  valued in the  market as though it has the
earlier maturity.

                                       6
<PAGE>
LENDING OF SECURITIES

Each Fund may lend its  securities.  A lending  policy may be  authorized by the
Trust's Board of Trustees and implemented by the Manager,  but securities may be
loaned only to qualified broker-dealers or institutional investors that agree to
maintain cash  collateral  with the Trust equal at all times to at least 100% of
the value of the loaned securities.  The Trustees will establish  procedures and
monitor the  creditworthiness  of any institution or  broker-dealer  during such
times as any loan is outstanding. The Trust will continue to receive interest on
the  loaned  securities  and will  invest  the  cash  collateral  in  short-term
obligations of the U.S. Government or of its agencies or instrumentalities or in
repurchase agreements, thereby earning additional interest.

     No loan of securities  will be made if, as a result,  the aggregate of such
loans would exceed 33 1/3% of the value of a Fund's total assets.  The Trust may
terminate such loans at any time.

FOREIGN SECURITIES

Each Fund,  except the Growth and Tax Strategy  Fund,  GNMA,  and Treasury Money
Market Trusts, may invest their assets in foreign securities purchased in either
foreign or U.S.  markets,  including  American  Depositary  Receipts  (ADRs) and
Global Depositary Receipts (GDRs). These foreign holdings may include securities
issued in emerging markets as well as securities issued in established  markets.
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;   and  difficulties  in
obtaining legal judgments.  In the past,  equity and debt instruments of foreign
markets  have  been more  volatile  than  equity  and debt  instruments  of U.S.
securities markets.

FORWARD CURRENCY CONTRACTS

Each Fund,  except the Growth and Tax Strategy  Fund,  GNMA,  and Treasury Money
Market  Trusts,  may enter into forward  currency  contracts in order to protect
against  uncertainty  in the level of future foreign  exchange  rates. A forward
contract  involves an  agreement  to  purchase or sell a specific  currency at a
specified future date or over a specified time period at a price set at the time
of the contract.  These contracts are usually traded directly  between  currency
traders (usually large commercial banks) and their customers. A forward contract
generally has no deposit requirements, and no commissions are charged.

     The  Funds  may  enter   into   forward   currency   contracts   under  two
circumstances.  First,  when a 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,  a 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 a 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.  A Fund may
not hedge with respect to a particular  currency for an amount  greater than the
aggregate  market  value  (determined  at the time of making any sale of forward
currency) of the securities  held in its portfolio  denominated or quoted in, or
bearing a substantial correlation to, such currency.

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

                                       7
<PAGE>
     Although  the Funds value their  assets each  business day in terms of U.S.
dollars,  they do not  intend to  convert  their  foreign  currencies  into U.S.
dollars on a daily basis.  They will do so from time to time,  and  shareholders
should be aware of currency conversion costs.  Although foreign exchange dealers
do not  charge a fee for  conversion,  they do  realize  a  profit  based on the
difference  (spread)  between  the prices at which  they are buying and  selling
various  currencies.  Thus, a dealer may offer to sell a foreign currency to the
Fund at one rate,  while  offering  a lesser  rate of  exchange  should the Fund
desire to resell that currency to the dealer.

WHEN-ISSUED SECURITIES

Each Fund may invest in new issues of debt  securities  offered on a when-issued
basis;  that is, delivery of and payment for the securities take place after the
date of the  commitment  to  purchase,  normally  within  45 days.  The  payment
obligation  and the interest  rate that will be received on the  securities  are
each fixed at the time the buyer  enters  into the  commitment.  A Fund may sell
these securities before the settlement date if it is deemed advisable.

     Debt securities  purchased on a when-issued basis are subject to changes in
value in the same way that other debt securities  held in the Funds'  portfolios
are; that is, both generally experience appreciation when interest rates decline
and  depreciation  when interest rates rise. The value of such  securities  will
also be affected  by the  public's  perception  of the  creditworthiness  of the
issuer  and  anticipated  changes  in the level of  interest  rates.  Purchasing
securities on a when-issued  basis involves a risk that the yields  available in
the market  when the  delivery  takes  place may  actually  be higher than those
obtained in the transaction itself. Cash or high-quality, liquid-debt securities
equal to the amount of the when-issued  commitments are segregated at the Fund's
custodian  bank.  The  segregated  securities  are valued at  market,  and daily
adjustments are made to keep the value of the cash and segregated  securities at
least equal to the amount of such commitments by the Fund.

     On the settlement  date of the when-issued  securities,  the Fund will meet
its obligations from then available cash, sale of segregated securities, sale of
other securities,  or from sale of the when-issued  securities themselves (which
may have a value greater or less than the Trust's payment obligations).  Sale of
securities to meet such obligations  carries with it a greater potential for the
realization of capital gains.

INVESTMENTS IN REAL ESTATE INVESTMENT TRUSTS (REITs)

Because the Income Strategy,  Balanced Strategy,  Cornerstone  Strategy,  Growth
Strategy,  and World Growth Funds may invest a portion of their assets in equity
securities of REITs,  the Funds may also be subject to certain risks  associated
with direct  investments in REITs. In addition,  the Income  Strategy,  Balanced
Strategy,  and Growth Strategy Funds may invest a portion of 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.

PUT AND CALL OPTIONS, FINANCIAL FUTURES CONTRACTS,  OPTIONS ON FINANCIAL FUTURES
CONTRACTS

Although the GNMA Trust,  Income Strategy,  Balanced Strategy,  Growth Strategy,
and Emerging Markets Funds are permitted to purchase and sell these contracts or
options,  the Funds have no current intention of doing so in the coming year and
will not engage in such  transactions  without first notifying  shareholders and
supplying further information in each Fund's Prospectus.

TAX-EXEMPT SECURITIES

Tax-exempt  securities  generally include debt obligations  issued by states and
their political subdivisions, and duly constituted authorities and corporations,
to obtain funds to construct,  repair, or improve various public facilities such
as airports, bridges, highways,  hospitals, housing, schools, streets, and water
and  sewer  works.  Tax-exempt  securities  may  also  be  issued  to  refinance
outstanding  obligations  as well  as to  obtain  funds  for  general  operating
expenses and for loans to other public institutions and facilities.

     The two principal  classifications  of tax-exempt  securities  are "general
obligations" and "revenue" or "special tax" bonds.  General obligation bonds are
secured by the  issuer's  pledge of its full faith,  credit and taxing power for
the payment of principal and interest.  Revenue or special tax bonds are payable
only from the revenues derived from a particular facility or class of facilities
or, in some cases, from the proceeds of a

                                       8
<PAGE>
special  excise or other tax, but not from general tax  revenues.  The Funds may
also  invest in  tax-exempt  private  activity  bonds,  which in most  cases are
revenue  bonds and generally do not have the pledge of the credit of the issuer.
The payment of the  principal and interest on such  industrial  revenue bonds is
dependent  solely on the ability of the user of the  facilities  financed by the
bonds to meet its  financial  obligations  and the  pledge,  if any, of real and
personal  property  so  financed as  security  for such  payment.  There are, of
course, many variations in the terms of, and the security underlying  tax-exempt
securities.  Short-term obligations issued by states, cities,  municipalities or
municipal agencies,  include Tax Anticipation Notes, Revenue Anticipation Notes,
Bond Anticipation Notes, Construction Loan Notes, and Short-Term Notes.

     The yields of tax-exempt securities depend on, among other things,  general
money market conditions, conditions of the tax-exempt bond market, the size of a
particular  offering,  the  maturity  of the  obligation,  and the rating of the
issue. The ratings of Moody's  Investors  Service,  Inc.  (Moody's),  Standard &
Poor's  Ratings Group (S&P),  Fitch IBCA,  Inc.  (Fitch),  and Duff & Phelps LLC
represent  their  opinions of the quality of the  securities  rated by them, see
APPENDIX A. It should be  emphasized  that such  ratings are general and are not
absolute standards of quality. Consequently,  securities with the same maturity,
coupon,  and rating may have  different  yields,  while  securities  of the same
maturity and coupon but with different  ratings may have the same yield. It will
be the  responsibility of the Manager to appraise  independently the fundamental
quality of the tax-exempt securities included in a Fund's portfolio.

REPURCHASE AGREEMENTS

Each Fund,  except the Growth and Tax Strategy  Fund,  may invest in  repurchase
agreements which 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  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,  except the Treasury  Money Market  Trust,  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.

                           SPECIAL RISK CONSIDERATIONS

CURRENCY EXCHANGE RATE FLUCTUATIONS

The Income Strategy,  Balanced Strategy,  Cornerstone Strategy, Growth Strategy,
Emerging  Markets,  Gold,  International,  and World Growth Funds' assets may be
invested in securities of foreign issuers.  Any such investments will be made in
compliance  with U.S.  and foreign  currency  restrictions,  tax laws,  and laws
limiting  the  amount and types of  foreign  investments.  Pursuit of the Funds'
investment  objectives  will  involve  currencies  of the  United  States and of
foreign   countries.   Consequently,   changes  in  exchange   rates,   currency
convertibility,  and repatriation requirements may favorably or adversely affect
the Funds.

UNPREDICTABLE POLITICAL, ECONOMIC AND SOCIAL CONDITIONS

For  the  Income  Strategy,  Balanced  Strategy,  Cornerstone  Strategy,  Growth
Strategy,  Emerging  Markets,  Gold,  International,  and  World  Growth  Funds,
investing in  securities  of foreign  issuers  presents  certain other risks not
present in domestic investments,  including different accounting, reporting, and
disclosure  requirements  for  foreign  issuers,  possible  political  or social
instability,  including  policies of foreign  governments which may affect their
respective  equity  markets,   and  foreign  taxation   requirements   including
withholding taxes.

                             INVESTMENT RESTRICTIONS

The following  investment  restrictions  have been adopted by the Trust for each
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 that  Fund's
outstanding voting securities.  The investment restrictions of one Fund may thus
be changed without affecting those of any other Fund.

     Under the  restrictions,  each of the Growth and Tax Strategy,  Cornerstone
Strategy, Gold, International, and World 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
      Investment  Company Act of 1940,  as amended  (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.

 (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)  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.

 (4)  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.

 (5)  Purchase securities on margin or sell securities short, except that it may
      obtain such  short-term  credits as are  necessary  for the  clearance  of
      securities transactions.

 (6)  Invest in put, call, straddle,  or spread options or interests in oil, gas
      or other mineral exploration or development  programs,  except that it may
      purchase  securities of issuers whose principal  business  activities fall
      within  such  areas in  accordance  with  its  investment  objectives  and
      policies.

 (7)  Invest more than 2% of the market value of its total assets in  marketable
      warrants  to  purchase  common  stock.   Warrants  initially  attached  to
      securities and acquired by a Fund upon original  issuance thereof shall be
      deemed to be without value.

 (8)  Purchase or sell real estate or partnership interests therein, except that
      the  Cornerstone  Strategy  Fund may purchase  securities  secured by real
      estate  interests  or  interests  therein,   or  issued  by  companies  or
      investment trusts which invest in real estate or interests therein.

 (9)  Purchase or sell commodities or commodity contracts.

 (10) Purchase securities of other open-end investment companies,  except a Fund
      may  invest  up to 10% of the  market  value of its  total  assets in such
      securities  through  purchases in the open market involving only customary
      broker's  commissions  or in  connection  with  a  merger,  consolidation,
      reorganization, or acquisition of assets approved by the shareholders.

 (11) Invest  more  than 5% of the  market  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.

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

 (13) Issue senior securities as defined in the 1940 Act, except as permitted by
      Section 18(f)(2) and rules thereunder.

 (14) Invest more than 25% of its total assets in one industry.

     For purposes of  restriction  8 above,  interests  in publicly  traded Real
Estate Investment Trusts (REITs) are not deemed to be real estate or partnership
interests therein.

Each of the GNMA and Treasury Money Market Trusts 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

      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.

      limitation does not apply to purchases of debt securities or to repurchase
      agreements.

 (4)  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

      value of its total  assets  will be  invested  in  securities  of  issuers
      principally  engaged in a particular industry (except that such limitation
      does not apply to obligations issued or guaranteed by the U.S.  Government
      or its agencies or instrumentalities).

The Emerging Markets Fund 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 that it may borrow money 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), nor will it
      purchase securities when its borrowings exceed 5% of its total assets.

 (3)  Concentrate its investments in any one industry  although it may invest up

      U.S. Government or its corporate instrumentalities.

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

      agreements.

 (7)  Purchase or sell commodities, except that the 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  backed by real estate or  securities of
      companies  that deal in real  estate  or are  engaged  in the real  estate
      business.

Each of the Income Strategy,  Balanced  Strategy,  and Growth Strategy 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)  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;  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.

      be deemed to act as a statutory  underwriter  in the  distribution  of any

      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.

                                       11
<PAGE>
 (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 (S&P) 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 S&P have
unique  investment  characteristics,   additional  industries  are  included  as
industry  classifications.  The  Manager  classifies  municipal  obligations  by
projects with similar characteristics,  such as toll road revenue bonds, housing
revenue bonds or higher  education  revenue bonds. In addition,  the Cornerstone
Strategy Fund may not concentrate  investments in any one industry,  although it
may invest up to 25% of the value of its total assets in one industry; the Basic
Value  Stocks,   Foreign  Stocks,  and  U.S.  Government  Securities  investment
categories are not considered industries for this purpose.

ADDITIONAL RESTRICTION

The following  restriction is not  considered to be a fundamental  policy of the
Funds.  The Board of Trustees  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  Trust's  Board of  Trustees,  places all
orders for the purchase  and sale of Fund  securities.  In  executing  portfolio
transactions and selecting brokers and dealers, it is the Trust'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 Trust's  Board of Trustees 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 Trust's Board of Trustees 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 used to purchase securities for the
Income  Strategy,  Growth  and  Tax  Strategy,  Balanced  Strategy,  Cornerstone
Strategy,  Growth Strategy,  Emerging Markets,  Gold,  International,  and World
Growth  Funds,  preference  may be  given to those  broker-dealers  who  provide
statistical  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. These research services may also include access to research on third
party data bases,  such as historical data on companies,  financial  statements,
earnings  history and estimates,  and corporate  releases;  real-time quotes and
financial  news;  research  on specific  fixed  income  securities;  research on
international  market news and securities;  and rating services on companies and
industries.  In return  for such  services,  a Fund may pay to a broker a higher
commission  than may be  charged by other  brokers,  provided  that the  Manager
determines  in good faith that such  commission is reasonable in relation to the
value of the brokerage and research services provided by such broker,  viewed in
terms of either that particular  transaction or of the overall responsibility of
the Manager to the Funds and its other clients. The Manager continuously reviews
the performance of

                                       12
<PAGE>
the broker-dealers  with whom it places orders for transactions.  The receipt of
research from  broker-dealers  that execute  transactions on behalf of the Trust
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 Trust. 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 Trust.  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 TRUST'S MANAGER.

     Securities of the same issuer may be  purchased,  held, or sold at the same
time by the Trust 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 Trust, 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 Trust
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 Trust. In some instances,  this procedure may impact the price and
size of the position obtainable for the Trust.

     The Trust 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 May 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.

During the last three fiscal years, the Funds paid the following  brokerage fees
to USAA Brokerage Services, a discount brokerage service of the Manager:

         Fund                          1997            1998           1999*

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

   *  These  amounts  are  22.4%,  30.4%,  16.1%,  2.2%,  7.1%,  -%,  and  3.7%,
respectively, of brokerage fees paid by each Fund.

For the year ended May 31, 1999, 25.9%,  26.3%, 19.4%, 4.9%, 11.7%, and 7.6%, of
the  aggregate   dollar  amounts  of  transactions   involving  the  payment  of
commissions by the Income Strategy, Growth and Tax Strategy,  Balanced Strategy,
Cornerstone  Strategy,  Growth Strategy,  and World Growth Funds,  respectively,
were effected through USAA Brokerage Services.

     The  Manager  directed a portion of the Funds'  brokerage  transactions  to
certain broker-dealers that provided the Manager with research,  statistical and
other  information.  Such  transactions  amounted  to  $6,208,774,  $58,950,062,
$22,575,215,  $101,176,414,   $20,736,073,  and  $39,783,928,  and  the  related
brokerage commissions or underwriting commissions were $5,507, $63,060, $20,025,
$107,285,  $23,362,  and  $45,127,  for  the  Income  Strategy,  Growth  and Tax
Strategy,  Balanced Strategy,  Cornerstone Strategy,  Growth Strategy, and World
Growth Funds, respectively, for the year ended May 31, 1999.

PORTFOLIO TURNOVER RATES

The rate of  portfolio  turnover in any of the Funds  (other  than the  Treasury
Money Market Trust) will not be a limiting factor when the Manager deems changes
in a Fund's portfolio appropriate in view of its investment objective.  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. A higher degree of
equity  portfolio  activity will increase  brokerage  costs to a Fund. It is not
anticipated that the portfolio turnover rates of the Income Strategy, Growth and
Tax Strategy, Balanced Strategy, Cornerstone Strategy, Growth Strategy, Emerging
Markets,  Gold,  International,  and World  Growth  Funds or the GNMA Trust will
exceed 100%.

     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  and  short-term  U.S.  Government  securities  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
        ----                               ----               ----

     Income Strategy                       7.15%           117.12%*
     Growth and Tax Strategy (1)          65.58%            63.42%
     Balanced Strategy                    22.18%            63.39%
     Cornerstone Strategy                 32.73%            46.27%
     Growth Strategy                      69.42%            41.65%
     Emerging Markets                     41.23%            83.84%
     Gold                                 19.62%            33.48%
     International                        42.97%            37.69%
     World Growth                         45.04%            51.19%
     GNMA Trust                           60.85%            64.93%

- ------------------
  * The turnover rate was  significantly  higher due to the restructuring of the
portfolio to make the Fund more tax efficient.

  1  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:

                             DESCRIPTION OF SHARES

The Funds are series of the Trust and are diversified.  The Trust is an open-end
management  investment company established under the laws of the Commonwealth of
Massachusetts  pursuant to the First Amended and Restated Master Trust Agreement
(Master  Trust  Agreement),  dated  June 2,  1995,  as  amended.  The  Trust  is
authorized to issue shares of beneficial interest in separate portfolios. Eleven
such portfolios have been established which are described in this SAI. Under the
Master  Trust  Agreement,  the Board of  Trustees  is  authorized  to create new
portfolios  in addition to those  already  existing  without the approval of the
shareholders  of the  Trust.  The  Cornerstone  Strategy  and  Gold  Funds  were
established May 9, 1984, by the Board of Trustees and commenced  public offering
of their shares on August 15,  1984.  The  International  Fund,  established  on
November 4, 1987,  commenced public offering of its shares on July 11, 1988. The
Growth and Tax Strategy Fund was  established on November 3, 1988, and commenced
public  offering of its shares on January  11,  1989.  On November 7, 1990,  the
Board of Trustees established the GNMA Trust and Treasury Money Market Trust and
commenced  public offering of their shares on February 1, 1991. The World Growth
Fund was  established  on July 21, 1992,  and commenced  public  offering of its
shares on  October  1,  1992.  The  Emerging  Markets  Fund was  established  on
September 7, 1994,  and commenced  public  offering of its shares on November 7,
1994. The Income  Strategy,  Balanced  Strategy,  and Growth Strategy Funds were
established  on June 2, 1995, and commenced  public  offering of their shares on
September 1, 1995.

     Each Fund's assets, and all income, earnings, profits and proceeds thereof,
subject  only to the rights of  creditors,  are  specifically  allocated to each
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 Trust 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  Trustees
determine 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 Trustees.  Upon  liquidation of that
Fund, shareholders are entitled to share pro rata in the net assets belonging to
such Fund available for distribution.

     Under the Trust's Master Trust  Agreement,  no annual or regular meeting of
shareholders is required.  Thus, there will ordinarily be no shareholder meeting
unless otherwise required by the 1940 Act. Under certain circumstances, however,
shareholders  may apply to the Trustees for shareholder  information in order to
obtain signatures to request a shareholder meeting. The Trust may fill vacancies
on the Board or appoint new  Trustees if the result is that at least  two-thirds
of the Trustees have still been elected by shareholders.  Moreover,  pursuant to
the Master Trust Agreement, any Trustee may be removed by the vote of two-thirds
of the  outstanding  Trust shares and holders of 10% or more of the  outstanding
shares of the Trust can require  Trustees to call a meeting of shareholders  for
the  purpose of voting on the  removal of one or more  Trustees.  The Trust will
assist in communicating to other shareholders  about the meeting.  On any matter
submitted to the  shareholders,  the holder of any 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.
For example, the Advisory Agreement must be approved separately by each Fund and
only becomes effective with respect to a Fund when a majority of the outstanding
voting  securities  of that Fund  approves  it.  Shareholders  of a Fund are not
entitled  to vote on any  matter  which  does not  affect  that  Fund but  which
requires a separate vote of another Fund. For example,  a proposed change in the
investment objectives of a particular Fund would require the affirmative vote of
a majority of the outstanding voting securities of only that Fund.

     Shares do not have cumulative voting rights, which means that in situations
in which  shareholders  elect  Trustees,  holders of more than 50% of the shares
voting for the election of Trustees can elect 100% of

                                       15
<PAGE>
the Board of Trustees, and the holders of less than 50% of the shares voting for
the election of Trustees will not be able to elect any person as a Trustee.

     When issued,  each Fund's  shares are fully paid and  nonassessable  by the
Trust, have no preemptive or subscription  rights,  and are fully  transferable.
There are no conversion rights.

                               TAX CONSIDERATIONS

TAXATION OF THE FUNDS

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,  a 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. In the
case of the  Growth  and Tax  Strategy  Fund,  in  order to be  entitled  to pay
exempt-interest  dividends to shareholders,  at the close of each quarter of its
taxable  year, at least 50% of the value of the Fund's total assets must consist
of  obligations  the  interest of which is exempt from  federal  income tax. The
Growth and Tax Strategy Fund intends to satisfy this requirement.

     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
excise tax.

     The  Income  Strategy,  Balanced  Strategy,  Cornerstone  Strategy,  Growth
Strategy, Emerging Markets, Gold, International, and World Growth Funds' ability
to make  certain  investments  may be  limited  by  provisions  of the Code that
require inclusion of certain unrealized gains or losses in the Fund's income for
purposes of the 90% test, and the distribution  requirements of the Code, and by
provisions  of the Code that  characterize  certain  income or loss as  ordinary
income  or  loss  rather  than   capital   gain  or  loss.   Such   recognition,
characterization  and timing rules  generally  apply to  investments  in certain
forward currency contracts,  foreign currencies and debt securities  denominated
in foreign currencies, as well as certain other investments.

     If the Income Strategy,  Balanced Strategy,  Cornerstone  Strategy,  Growth
Strategy, Emerging Markets, Gold, International, or World Growth Funds invest in
an entity that is classified as a "passive  foreign  investment  company" (PFIC)
for federal income tax purposes,  the  application of certain  provisions of the
Code applying to PFICs could result in the imposition of certain  federal income
taxes on the Fund.  It is  anticipated  that any taxes on a Fund with respect to
investments in PFICs would be insignificant.

TAXATION OF THE SHAREHOLDERS

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 a 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 exchange that is less than or equal to the amount
of the distribution  will be treated as long-term  capital loss, except as noted
below.

     In the case of the Growth and Tax Strategy Fund, if a shareholder  receives
an  exempt-interest  dividend  with respect to any share and such share has been
held for six months or less, any loss on the sale or exchange of such share will
be disallowed to the extent of such exempt-interest  dividend.  Shareholders who
are recipients of Social Security benefits should be aware that  exempt-interest
dividends received from the Growth and Tax Strategy Fund are includible in their
"modified  adjusted gross income" for purposes of determining the amount of such
Social  Security  benefits,  if any,  that are  required to be included in their
gross income.

                                       16
<PAGE>
     The Growth and Tax  Strategy  Fund may  invest in private  activity  bonds.
Interest on certain  private  activity  bonds issued after August 7, 1986, is an
item of tax  preference  for  purposes  of the Federal  Alternative  Minimum Tax
(AMT),  although the interest  continues to be excludable  from gross income for
other purposes.  AMT is a supplemental tax designed to ensure that taxpayers pay
at least a minimum amount of tax on their income,  even if they make substantial
use of certain tax  deductions  and  exclusions  (referred to as tax  preference
items).  Interest from private activity bonds is one of the tax preference items
that is added to income  from other  sources  for the  purposes  of  determining
whether a taxpayer is subject to AMT and the amount of any tax to be paid.

     Opinions  relating to the validity of the tax-exempt  securities  purchased
for the Growth and Tax Strategy Fund and the exemption of interest  thereon from
federal  income tax are  rendered by  recognized  bond  counsel to the  issuers.
Neither the  Manager's  nor the Fund's  counsel makes any review of the basis of
such opinions.

     The exemption of interest  income for federal  income tax purposes does not
necessarily  result in exemption under the income or other tax laws of any state
or local taxing  authority.  Shareholders of a Fund may be exempt from state and
local  taxes  on  distributions  of  tax-exempt  interest  income  derived  from
obligations of the state and/or  municipalities of the state in which they are a
resident, but generally are subject to tax on income derived from obligations of
other  jurisdictions.  Shareholders  should consult their tax advisers about the
status of distributions from a Fund in their own states and localities.

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

 (b)  At May 31, 1999,  the USAA Family of Funds  consisted  of four  registered
      investment  companies offering 35 individual funds. Each Trustee presently
      serves as a Trustee or  Director  of each  investment  company in the USAA
      Family of Funds.  In addition,  Michael J.C.  Roth  presently  serves as a
      Trustee

                                       19
<PAGE>
      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 Trustees are also  Trustees/Directors  of the other funds
within  the USAA  Family of Funds.  No  compensation  is paid by any fund to any
Trustee/Director  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 Trust  reimburses  certain  expenses of the  Trustees who are not
affiliated with the investment  adviser. As of August 31, 1999, the officers and
Trustees of the Trust and their  families as a group  owned  beneficially  or of
record less than 1% of the outstanding shares of the Trust.

     As of August 31, 1999, USAA and its affiliates  owned 303,025 shares (5.1%)
of the Income Strategy Fund,  24,008,365  shares (78.1%) of the Emerging Markets
Fund,  2,446,188 shares (9.7%) of the  International  Fund, and no shares of the
Growth and Tax Strategy Fund, Balanced Strategy Fund, Cornerstone Strategy Fund,
Growth  Strategy  Fund,  Gold Fund,  World Growth Fund,  GNMA Trust and Treasury
Money Market Trust.

     The Trust knows of no other  persons  who, as of August 31,  1999,  held of
record  or owned  beneficially  5% or more of the  voting  stock  of any  Fund's
shares.

                               THE TRUST'S MANAGER

As described in each Fund's  Prospectus,  USAA Investment  Management Company is
the Manager and  investment  adviser,  providing the 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,  has served as  investment  adviser and
underwriter for USAA Investment Trust from its inception.

     In addition to managing the Trust's assets, the Manager advises and manages
the investments  for USAA and its affiliated  companies as well as those of USAA
Mutual Fund,  Inc., USAA Tax Exempt Fund,  Inc., 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
$27 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. A copy of the Joint Code of Ethics has been
filed with the  Securities  and Exchange  Commission and is available for public
view.

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 Trustees
of the  Trust,  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 Trust.  The
Manager compensates all personnel,  officers,  and Trustees of the Trust if such
persons are also employees of the Manager or its affiliates.  For these services
under the  Advisory  Agreement,  each Fund has  agreed to pay the  Manager a fee
computed as described under FUND  MANAGEMENT in its Prospectus.  Management fees
are computed and accrued daily and are payable monthly.

     Except for the services and facilities  provided by the Manager,  the Funds
pay all other  expenses  incurred in their  operations.  Expenses  for which the
Funds are responsible include taxes (if any); brokerage commissions on portfolio
transactions (if any); expenses of issuance and redemption of shares; charges of
transfer agents,  custodians, and dividend disbursing agents; costs of preparing
and  distributing  proxy  material;   costs  of  printing  and  engraving  stock
certificates;  auditing and legal expenses;  certain expenses of registering and
qualifying  shares  for  sale;  fees of  Trustees  who are not  interested  (not
affiliated)  persons  of

                                       20
<PAGE>
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 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 Trustees
(on  behalf of such  Fund)  including  a majority  of the  Trustees  who are not
interested  persons of the Manager or (otherwise than as Trustees) of the Trust,
at a meeting  called for the purpose of voting on such  approval.  The  Advisory
Agreement may be terminated at any time by either the Trust or the Manager on 60
days'  written  notice.  It will  automatically  terminate  in the  event of its
assignment (as defined by 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 Balanced Strategy Fund to 1.25% of the Fund's ANA, until October
1,  2000,  and will  reimburse  the  Fund for all  expenses  in  excess  of such
limitation.  After  October 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

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

TRANSFER AGENT

The  Transfer  Agent  performs  transfer  agent  services  for the Trust under a
Transfer Agency Agreement.  Services include  maintenance of shareholder account
records,  handling of  communications  with  shareholders,  distribution of Fund
dividends,  and  production  of reports  with  respect to account  activity  for
shareholders  and  the  Trust.  For  its  services  under  the  Transfer  Agency
Agreement,  each Fund  pays the  Transfer  Agent an  annual  fixed fee of $26 to
$28.50 per account. The fee is subject to change at any time.

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

                         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 each
Fund's price per share is calculated.

YIELD - TREASURY MONEY MARKET TRUST

When the Treasury Money Market Trust 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
Trust'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  Trust'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 May 31, 1999, was 4.42%.
        Effective Yield For 7-day Period ended May 31, 1999, was 4.52%.

YIELD - INCOME STRATEGY FUND, GROWTH AND TAX STRATEGY FUND, AND GNMA TRUST

These Funds may advertise  performance in terms of 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

                                       22
<PAGE>
The 30-day  yields for the period  ended May 31, 1999,  for the Income  Strategy
Fund, Growth and Tax Strategy Fund, and GNMA Trust were 3.94%,  2.63% and 6.28%,
respectively.

TAX-EQUIVALENT YIELD

A  tax-exempt  mutual  fund may  provide  more  "take-home"  income than a fully
taxable  mutual fund after paying taxes.  Calculating a  "tax-equivalent  yield"
means converting a tax-exempt yield to a pretax  equivalent so that a meaningful
comparison  can be made between a tax-exempt  municipal fund and a fully taxable
fund. Because the Growth and Tax Strategy Fund invests a significant  percentage
of its assets in tax-exempt securities, it may advertise performance in terms of
a 30-day tax-equivalent yield.

     To  calculate a  tax-equivalent  yield,  an investor  must know his federal
marginal  income  tax rate.  The  tax-equivalent  yield for the  Growth  and Tax
Strategy  Fund is then  computed by dividing  that portion of the yield which is
tax exempt by the  complement  of the federal  marginal  tax rate and adding the
product to that  portion of the yield  which is  taxable.  The  complement,  for
example,   of  a  federal  marginal  tax  rate  of  36.0%  is  64.0%,   that  is
(1.00-0.36=0.64).

           Tax-Equivalent Yield = (% Tax-Exempt Income x 30-day Yield/
                         (1-Federal Marginal Tax Rate))
                       + (% Taxable Income x 30-day Yield)

     Based on a federal marginal tax rate of 36.0%, the tax-equivalent yield for
the Growth and Tax Strategy Fund for the period ended May 31, 1999, was 3.87%.

TOTAL RETURN

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

                                P(1 + T)n = ERV

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

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

                          Average Annual Total Returns
                         For Periods Ended May 31, 1999

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

1.  LONG-TERM DEBT RATINGS:

MOODY'S INVESTOR SERVICES, INC.

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

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

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

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

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.

A description of ratings Ba and below assigned to debt obligations by Moody's is
included in Appendix A of the Emerging Markets Fund Prospectus.

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.

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

FITCH IBCA, INC.

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.

                                       24
<PAGE>
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 AND 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 LLC

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 MUNICIPAL

MIG-1/VMIG1           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.

MIG-2/VMIG2           This   designation   denotes   high  quality.  Margins  of
                      protection  are  ample  although  not so large as in the
                      preceding group.

MOODY'S CORPORATE AND GOVERNMENT

Prime-1    Issuers rated Prime-1 (or  supporting  institutions)  have a superior
           ability for repayment of senior  short-term  promissory  obligations.
           Prime-1  repayment   capacity  will  normally  be  evidenced  by  the
           following characteristics:

           o Leading market positions in well-established industries.
           o High rates of return on funds employed.
           o Conservative capitalization  structures with moderate  reliance on
             debt and ample asset protection.
           o Broad margins in earning 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  promissory  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.

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.

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

FITCH

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

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

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 quality 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.

                        HOW DOLLAR-COST AVERAGING WORKS

         officers and trustees of the Registrant is provided by two methods:

     (a) THE DIRECTOR AND  OFFICER  LIABILITY  POLICY.  This policy  covers all
         losses  incurred by the  Registrant,  its adviser and its  underwriter
         from any claim made  against  those  entities  or  persons  during the
         policy period by any shareholder or former  shareholder of any Fund by
         reason of any alleged  negligent act,  error or omission  committed in
         connection  with  the   administration  of  the  investments  of  said
         Registrant  or in  connection  with the sale or  redemption  of shares
         issued by said  Registrant.  The Trust will not pay for such insurance
         to the extent that payment  therefor is in violation of the Investment
         Company Act of 1940 or the Securities Act of 1933.

     (b) INDEMNIFICATION PROVISIONS UNDER AGREEMENT AND  DECLARATION  OF TRUST.
         Under  Article  VI of  the Registrant's  Agreement and  Declaration of
         Trust,  each of  its  trustees and  officers or any person  serving at
         the Registrant's request as a director,  officer or trustee of another
         entity in which the  Registrant  has any  interest  as a  shareholder,
         creditor or otherwise  ("Covered Person") shall be indemnified against
         all  liabilities,  including  but  not  limited  to  amounts  paid  in
         satisfaction  of judgments,  in compromise or as fines and  penalties,
         and  expenses,  including  reasonable  accountants'  and counsel fees,
         incurred  by any  Covered  Person in  connection  with the  defense or
         disposition of any action, suit or other proceeding,  whether civil or
         criminal,  before any court or  administrative or legislative body, in
         which such person may be or may have been threatened,  while in office
         or  thereafter,  by reason of being or  having  been such an  officer,
         director or trustee,  except with respect to any matter as to which it
         has been  determined  that such Covered Person (i) did not act in good
         faith in the reasonable  belief that such Covered  Person's action was
         in or not opposed to the best interests of the Trust or (ii) had acted
         with willful  misfeasance,  bad faith,  gross  negligence  or reckless
         disregard  of the  duties  involved  in the  conduct  of such  Covered
         Person's  office (either and both of the conduct  described in (i) and
         (ii)  being   referred  to  hereafter  as  "Disabling   Conduct").   A
         determination  that the Covered Person is entitled to  indemnification
         may be made by (i) a final  decision on the merits by a court or other
         body before  whom the  proceeding  was  brought  that the person to be
         indemnified  was not  liable  by  reason of  Disabling  Conduct,  (ii)
         dismissal of a court action or an administrative  proceeding against a
         Covered Person for insufficiency of evidence of Disabling Conduct,  or
         (iii) a  reasonable  determination,  based upon a review of the facts,
         that the indemnitee  was not liable by reason of Disabling  Conduct by
         (a) a vote of a  majority  of a quorum  of  trustees  who are  neither
         "interested  persons" of the Registrant as defined in section 2(a)(19)
         of the 1940 Act nor parties to the  proceeding,  or (b) an independent
         legal counsel in a written opinion.

                                   C-4
<PAGE>
         Expenses,  including  accountants  and counsel  fees so incurred by any
         such Covered  Person (but  excluding  amounts paid in  satisfaction  of
         judgments,  in compromise or as fines or  penalties),  may be paid from
         time to time by the Fund of the  Registrant  in  question in advance of
         the final disposition of any such action, suit or proceeding,  provided
         that the covered  person shall have  undertaken to repay the amounts so
         paid  to  the  Fund  of  Registrant  in  question  if it is  ultimately
         determined  that  indemnification  of such  expenses is not  authorized
         under Article VI of the Agreement and  Declaration of Trust and (i) the
         Covered Person shall have provided security for such undertaking,  (ii)
         the Registrant shall be insured against losses arising by reason of any
         lawful advances,  or (iii) a majority of a quorum of the  disinterested
         trustees who are not a party to the proceeding, or an independent legal
         counsel in a written opinion, shall have determined,  based on a review
         of readily  available  facts (as opposed to full  trial-type  inquiry),
         that there is reason to believe that the Covered Person ultimately will
         be found entitled to indemnification. As to any matter disposed of by a
         compromise  payment by any such  Covered  Person  pursuant to a consent
         decree or otherwise, no such indemnification either for said payment or
         for any other  expenses shall be provided  unless such  indemnification
         shall be approved  (a) by a majority of the  disinterested  trustees of
         the  Registrant  who  are not a party  to the  proceeding  or (b) by an
         independent  legal  counsel  in a  written  opinion.  Approval  by  the
         trustees  pursuant  to  clause  (a)  or by  independent  legal  counsel
         pursuant to clause (b) shall not prevent the recovery  form any Covered
         Person of any amount paid to such Covered Person in accordance with any
         of  such  clauses  as   indemnification   if  such  Covered  Person  is
         subsequently  adjudicated by a court of competent  jurisdiction  not to
         have acted in good faith in the  reasonable  belief  that such  Covered
         Person's  action  was in or not  opposed to the best  interests  of the
         Registrant or to have been liable to the Registrant or its shareholders
         by reason of  willful  misfeasance,  bad  faith,  gross  negligence  or
         reckless  disregard  of the  duties  involved  in the  conduct  of such
         Covered Person's office.

         Insofar as indemnification for liabilities arising under the Securities
         Act of 1933 may be  permitted to  trustees,  officers  and  controlling
         persons of the Registrant  pursuant to the  Registrant's  Agreement and
         Declaration of the Trust 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  trustee,  officer  or
         controlling  person of the Registrant in the successful  defense of any
         action,  suit or  proceeding)  is asserted by such trustee,  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.
