RISK/RETURN SUMMARY                                    SM&R GOVERNMENT BOND FUND
    
- -------------------------------------------------------------------
 
   
GOVERNMENT BOND FUND'S INVESTMENT OBJECTIVE
                   To provide as high a level of current income,
                   liquidity, and safety of principal as is consistent with
                   prudent investment risks through investment in a portfolio
                   consisting primarily of securities issued or guaranteed by
                   the U.S. Government, its agencies, or instrumentalities.
    
 
   
GOVERNMENT BOND FUND'S PRINCIPAL INVESTMENT STRATEGIES
                   The Government Bond Fund normally invests at
                   least 65% of its assets in securities issued or guaranteed by
                   the U.S. Government, its agencies, or instrumentalities.
                   These may include Treasuries and mortgage-backed securities,
                   such as Ginnie Maes, Freddie Macs, and Fannie Maes. This fund
                   may also invest assets in collateralized mortgage
                   obligations.
    
 
   
                   The Government Bond Fund may invest in zero coupon bonds,
                   which are U.S. Government obligations. The fund may also
                   invest in commercial paper, certificates of deposit,
                   corporate debt securities rated "A" or higher, and repurchase
                   agreements.
    
 
   
PRINCIPAL RISKS OF INVESTING IN THE GOVERNMENT BOND FUND
                   You could lose money on your investment in the
                   Government Bond Fund, or it could underperform other
                   investments, if any of the following occurs:
    
   
                   - interest rates rise (thus causing a decline in the market
                     value of debt securities)
    
   
                   - the worldwide demand for U.S. government securities falls
    
   
                   - interest rates fall enough to prompt an unexpected number
                     of people to refinance (or prepay) their mortgages
    
   
                   - interest rates rise enough to cause fewer people than
                     expected to repay their mortgages early
    
   
                   - if any bonds the fund owns are downgraded in credit rating
                     or go into default

WHO MAY WANT TO INVEST IN THE GOVERNMENT BOND FUND
                   The Government Bond Fund may be
                   appropriate if you:
    
   
                   - are seeking a regular stream of income to meet current
                     needs
    
   
                   - are seeking higher potential returns than money market
                     funds and are willing to accept moderate risk of volatility
    
   
                   - are retired or nearing retirement
    
 
   
                   The Government Bond Fund may NOT be appropriate if you:
    
   
                   - are investing for maximum return over a long time horizon
    
   
                   - require absolute stability of your principal

RISK/RETURN SUMMARY                                           SM&R TAX FREE FUND
    
- -------------------------------------------------------------------
 
   
TAX FREE FUND'S INVESTMENT OBJECTIVE
                   To provide as high a level of interest income
                   largely exempt from federal income taxes as is consistent
                   with preservation of capital through investment of at least
                   80% of its net assets in tax-exempt securities during normal
                   market conditions.
    
 
   
TAX FREE FUND'S PRINCIPAL INVESTMENT STRATEGIES
                   The Tax Free Fund invests primarily in tax-
                   exempt securities. During normal market conditions, this fund
                   invests at least 80% of its assets in municipal securities
                   that pay interest exempt from federal income taxes. This fund
                   may not invest more than 20% of its assets in UNRATED
                   municipal securities. These securities may be less liquid
                   than comparably rated municipal securities and involve
                   somewhat greater risk. This fund may also invest up to 20% of
                   its assets in Government guaranteed taxable bonds, highly
                   rated corporate bonds, or commercial paper.
    
 
   
PRINCIPAL RISKS OF INVESTING IN THE TAX FREE FUND
                   You could lose money on your investment in the
                   Tax Free Fund, or it could underperform other investments, if
                   any of the following occurs:
    
   
                   - interest rates rise (thus causing a decline in the market
                     value of debt securities)
    
   
                   - if any bonds the fund owns are downgraded in credit rating
                     or go into default
    
   
                   - certain securities become harder to value or to sell at a
                     fair price
    
 
   
                   ALSO, SOME OF YOUR DIVIDEND INCOME MAY BE TAXABLE.

WHO MAY WANT TO INVEST IN THE TAX FREE FUND
    
                   The Tax Free Fund may be appropriate if you:
   
                   - are willing to sacrifice some investment return for income
                     exempt from federal income tax and, under certain
                     conditions, exempt from state and local taxes
    
   
                   - are in a high tax bracket (28% and up)
    
   
                   - are seeking a regular stream of income to meet current

RISK/RETURN SUMMARY                                            SM&R PRIMARY FUND
    
- -------------------------------------------------------------------
 
   
PRIMARY FUND'S INVESTMENT OBJECTIVE
                   To seek maximum current income consistent
                   with capital preservation and liquidity through investment
                   primarily in commercial paper.
    
 
   
PRIMARY FUND'S PRINCIPAL INVESTMENT STRATEGIES
                   The Primary Fund invests primarily in
                   commercial paper. Commercial paper is short-term unsecured
                   promissory notes issued by corporations. This fund will only
                   invest in commercial paper rated in one of the two highest
                   rating categories.
    
 
   
                   The Primary Fund may also invest in:
    
   
                   - U.S. Government obligations;
    
   
                   - corporate debt obligations maturing in five years or less
                     and rated "A" or higher;
    
   
                   - certificates of deposit; and
    
   
                   - repurchase agreements.
    
 
   
PRINCIPAL RISKS OF INVESTING IN THE PRIMARY FUND
                   You could lose money on your investment in the
                   Primary Fund, or it could underperform other investments, if
                   any of the following occurs:
    
   
                   - interest rates rise (thus causing a decline in the market
                     value of debt securities)
    
   
                   - if any of the fund's investments are downgraded in credit
                     rating or go into default
    
 
   
                   By limiting its investments as described above, the Primary
                   Fund may not achieve as high a level of current income as a
                   fund investing in lower-rated securities or longer-term
                   securities.

RISK/RETURN SUMMARY                                       SM&R MONEY MARKET FUND
    
- -------------------------------------------------------------------
 
   
MONEY MARKET FUND'S INVESTMENT OBJECTIVE
                   To seek the highest current income consistent
                   with the preservation of capital and maintenance of
                   liquidity.
    
 
   
MONEY MARKET FUND'S PRINCIPAL INVESTMENT STRATEGIES
                   The Money Market Fund seeks to achieve its
                   objective by investing in high-quality short-term money
                   market instruments, including: U.S. Government obligations,
                   certificates of deposit, banker's acceptances, commercial
                   paper, collateralized mortgage obligations, and corporate
                   bonds and notes. This fund limits its investments to those
                   short-term securities that it determines present minimal
                   credit risk and meet certain rating requirements (in the two
                   highest short-term rating categories).
    
 
   
PRINCIPAL RISKS OF INVESTING IN THE MONEY MARKET FUND
                   The Money Market Fund is subject to the
                   following risks:
    
   
                   - that interest rates may rise (thus causing a decline in the
                     market value of debt securities)
    
   
                   - that the fund's investments may be downgraded in credit
                     rating or go into default
    
 
   
                   However, the risks of investment in the Money Market Fund may
                   be expected to be less than for other mutual funds. By
                   limiting its investments as described above, this fund may
                   not achieve as high a level of current income as a fund
                   investing in lower-rated securities. Also, there is a remote
                   possibility that this fund's share value could fall below
                   $1.00, which could reduce the value of your account.

WHO MAY WANT TO INVEST IN THE MONEY MARKET FUND
                   The Money Market Fund may be appropriate if
                   you:
    
   
                   - require stability of principal
    
   
                   - are seeking a mutual fund for the cash portion of an asset
                     allocation program
    
   
                   - need to "park" your money temporarily
    
   
                   - consider yourself a saver rather than an investor
    
   
                   - are investing emergency reserves
    
 
   
                   The Money Market Fund may NOT be appropriate if you:
    
   
                   - want federal deposit insurance
    
   
                   - are seeking an investment that is likely to outpace
                     inflation
    
   
                   - are investing for retirement or other goals that are many
                     years in the future
    
   
                   - are investing for growth or maximum current income
    
   
AN INVESTMENT IN THE MONEY MARKET FUND IS NOT INSURED OR GUARANTEED BY THE
FEDERAL DEPOSIT INSURANCE CORPORATION OR ANY OTHER GOVERNMENT AGENCY. ALTHOUGH
THE MONEY MARKET FUND SEEKS TO PRESERVE THE VALUE OF YOUR INVESTMENT AT $1.00
PER SHARE, IT IS POSSIBLE TO LOSE MONEY BY INVESTING IN THE MONEY MARKET FUND.

RISK/RETURN SUMMARY
    
- -------------------------------------------------------------------
 
   
TYPES OF INVESTMENT RISK
    
 
   
As indicated above, each of the four funds may be subject to certain of the
following types of risks:
    
 
   
CREDIT RISK. The risk that the issuer of a security, or a party to a contract,
will default or otherwise not honor a financial obligation.
    
 
   
INTEREST RATE RISK. The risk of declines in market value of an income-bearing
investment due to changes in prevailing interest rates. With fixed-rate
securities, a rise in interest rates typically causes a decline in market
values, while a fall in interest rates typically causes an increase in market
values.
    
 
   
LIQUIDITY RISK. The risk that certain securities or other investments may be
difficult or impossible to sell at the time the fund would like to sell them or
at the price the fund values them. The fund may have to sell at a lower price,
sell other securities instead, or forego an investment opportunity, any of which
could have a negative effect on fund management or performance.
    
 
   
MANAGEMENT RISK. The risk that a strategy used by a fund's management may fail
to produce the intended result. This risk is common to all mutual funds.
    
 
   
MARKET RISK. The risk that the market value of a security may move up and down,
sometimes rapidly and unpredictably. The fluctuations may cause a security to be
worth less than the price originally paid for it, or less than it was worth at
an earlier time. Market risk may affect a single issuer, industry, sector of the
economy, or the market as a whole. This risk is common to all stocks and bonds
and the mutual funds that invest in them.
    
 
   
PREPAYMENT AND EXTENSION RISK. PREPAYMENT RISK is the risk that an unexpected
fall in prevailing interest rates will shorten the life of an outstanding
mortgage-backed security by increasing the actual or expected number of mortgage
prepayments, thereby reducing the security's value. EXTENSION RISK is the risk
that an unexpected rise in prevailing interest rates will extend the life of an
outstanding mortgage-backed security by reducing the actual or expected number
of mortgage prepayments, thereby reducing the security's value.

- ------------------------------------------------
 
   
BAR CHART AND PERFORMANCE TABLE
    
 
   
The bar charts and performance tables shown below provide some indication of the
risks of investing in the funds and the variability of returns by showing each
fund's performance for each year since inception and by showing how each fund's
average annual returns for certain periods compare to those of a broad-based
securities market index. Because the Money Market Fund was not in operation
during these periods, it is not included in the bar chart or the performance
table.
    
 
   
The returns shown are based on an investment in the funds prior to the creation
of multiple classes of shares, but do not reflect any sales loads that would be
imposed on the purchase or sale of any shares. If multiple classes of shares of
the Government Bond and Tax Free Funds had been in existence, the financial
performance of Class A, B, and C shares would have been lower than depicted
because of the imposition of distribution and/or service (12b-1) fees.
    
 
   
Past performance is not necessarily an indication of how the funds will perform
in the future.

RISK/RETURN SUMMARY
    
- ------------------------------------------------
 
   
  - 1.50% on initial investments of at least $500,000 but less than $1 million
    
 
   
  - zero on initial investments of $1 million or more
    
 
   
(2) You pay an $8.00 transaction fee for each expedited wire redemption.
    
 
   
(3) Purchases of $1 million or more of Class A shares may be made without an
    initial sales charge. Redemptions of such shares within the first thirteen
    months after purchase, however, will be subject to a contingent deferred
    sales charge of 1.00%.
    
 
   
(4) The maximum 3.00% contingent deferred sales charge on Class B shares applies
    to redemptions during the first year after purchase. The charge declines to
    2.00% during the second year, 1.00% during the third year, and zero during
    the fourth year and thereafter.
    
 
   
(5) A contingent deferred sales charge of 1.00% only applies to redemptions of
    Class C shares during the first thirteen months after purchase.
    
 
   
(6) "Other Expenses" include the 0.25% Administrative Service Fee. Because Class
    A, B, and C shares were not available prior to the date of this Prospectus,
    "Other Expenses" for Class A, B, and C shares are based on the expenses and
    average net assets of the Government Bond Fund and the Tax Free Fund for the
    fiscal year ended August 31, 1998. "Other Expenses" shown for the Money
    Market Fund are estimated for the current fiscal year ending August 31,

(7) The Fee Table does not reflect any fees waived or expenses assumed either
    contractually or voluntarily by the funds' manager, Securities Management

    expenses in excess of 1.25% (0.35% for the Money Market Fund) per year of
    such fund's average daily net assets. Regular operating expenses include the
    advisory fee and administrative fee, but do not include the 12b-1 fee or
    class-specific expenses.

EXAMPLES OF EXPENSES
    
 
   
These examples are intended to help you compare the cost of investing in the
funds with the cost of investing in other mutual funds. These examples assume
that you invest $10,000 in each fund and applicable class thereof for the time
periods indicated, based on expenses before fee waivers and expense
reimbursements. These examples also assume that your investment has a 5% return
each year and that the funds' operating expenses remain the same. YOUR ACTUAL
COSTS MAY BE HIGHER OR LOWER THAN SHOWN.
    
 
   
You would pay the following expenses, based on these assumptions, if you
actually redeem all of your shares at the end of the period shown:

SHARES OF THE FUNDS
    
- -------------------------------------------------------------------
 
   
SM&R Investments, Inc., formerly known as SM&R Capital Funds, Inc. (the
"Company" or "we") offers four separate investment portfolios. Two of the funds
offer multiple classes of shares with different sales charge and distribution
and service (12b-1) fee structures. Each class has its own cost structure,
allowing you to choose the class that best suits your circumstances and
preferences. Your financial representative can help you decide.
    
 
   
The Money Market and Primary Funds each consist of a single class of shares
offered at net asset value and do not impose any sales charges or distribution
and service (12b-1) fees. The Government Bond and Tax Free Funds offer three
classes of shares through this Prospectus, called Class A, Class B, and Class C.
The Government Bond and Tax Free Funds offer other classes through separate
prospectuses. The other classes can only be bought by specified types of
investors or through certain distribution chains. FOR MORE INFORMATION ON THE
OTHER CLASSES OF SHARES OR TO REQUEST A PROSPECTUS FOR ANOTHER CLASS, CALL
INVESTOR SERVICES AT (800) 231-4639.
    
 
   
You may select from among the following three classes of shares:
    
 
   
                                    CLASS A
                                (FRONT-END LOAD)
    
 
   
- - Front-end sales charges, as described below. There are several ways to reduce
  these charges, also described below.
    
 
   
- - Lower annual expenses than Class B or Class C shares.
    
   
                                    CLASS B
                                (BACK-END LOAD)
    
 
   
- - No front-end sales charge; all your money goes to work for you right away.
    
 
   
- - Higher annual expenses than Class A shares.
    
 
   
- - A deferred sales charge on shares you sell within three years of purchase, as
  described below.
    
 
   
- - Automatic conversion to Class A shares after eight years, thus reducing future
  annual expenses.
    
   
                                     CLASS C
                                  (LEVEL LOAD)
    
 
   
- - Lower front-end sales charge than Class A shares, as described below.

SALES CHARGES
    
- -------------------------------------------------------------------
 
   
CLASS A SALES CHARGES
    
 
   
The offering price of Class A shares is the net asset value plus a "front-end"
sales charge. The sales charge is a percentage of the offering price, as shown
in the following table:
    
 
   
<TABLE>

</TABLE>
    
 
   
INVESTMENTS OF $1 MILLION OR MORE. If you invest $1 million or more in Class A
shares, you do not pay any "front-end" sales charge. However, you will pay a
contingent deferred sales charge (CDSC) of 1.00% of the offering price if you
redeem those shares within 13 months after you bought them. The CDSC will be
calculated in the same manner as for Class B shares, as described below.
    
 
   
CLASS B SALES CHARGES
    
 
   
Class B shares are sold at net asset value, without any initial sales charge.
However, there is a CDSC on shares you sell within three years of buying them.
The CDSC shown in the following table is a percentage of the offering price:

                      Year 2                                        2.00%
                      Year 3                                        1.00%
                      Year 4+                                     None
</TABLE>
    
 
   
If the net asset value of shares being redeemed has increased since you bought
them, we do not impose any CDSC on such increase in net asset value. We do not
impose any CDSC on shares you buy with reinvested dividends or capital gain
distributions. We will minimize any applicable CDSC by assuming that an investor
(i) first redeems
    
 
                                       20
<PAGE>
   
Class B shares bought through reinvested dividends and capital gains
distributions, and (ii) next redeems Class B shares held the longest.
    
 
   
CLASS C SALES CHARGES
    
 
   
Class C shares are sold at the net asset value plus a "front-end" sales charge
of 1.00% of the offering price. A contingent deferred sales charge of 1.00% also
applies on redemptions of Class C shares during the first thirteen months after
purchase.
    
 
   
SALES CHARGE REDUCTIONS AND WAIVERS
    
- -------------------------------------------------------------------
 
   
REDUCING YOUR CLASS A SALES CHARGE
    
 
   
DISCOUNTS THROUGH CONCURRENT PURCHASES. To qualify for a reduced sales charge on
Class A shares, you may combine concurrent purchases of Class A shares of funds
managed by SM&R. Investors that are eligible to combine concurrent purchases to
qualify for a reduced sales charge include:
    
 
   
(1) Any individual;
    
 
   
(2) Any individual, his or her spouse, and trusts or custodial accounts for
    their minor children;
    
 
   
(3) A trustee or fiduciary of a single trust estate or single fiduciary account.
    
 
   
DISCOUNTS THROUGH A RIGHT OF ACCUMULATION. If you already own Class A or Class T
shares of a fund managed by SM&R, you may be able to receive a discount when you
buy additional shares. The amount you paid for the shares you already own may be
"accumulated"--I.E., combined together with the offering price of the new shares
you plan to buy--to achieve quantities eligible for discount.
    
 
   
LETTER OF INTENT. You may qualify for a reduced sales charge on purchases of
Class A shares of funds managed by SM&R by completing the Letter of Intent
section of the account application. Under a Letter of Intent, an investor
expresses an intention to purchase, within 13 months of the initial investment,
a specified amount of Class A shares of funds managed by SM&R which, if made
concurrently, would qualify for a reduced sales charge. Upon execution of the
Letter of Intent, the investor must make a minimum
    
 
                                       21
<PAGE>
   
initial investment equal to ten percent (10%) of the amount necessary to qualify
for the applicable reduced sales charge. To assure that the full applicable
sales charge will be paid if the intended purchase is not completed, five
percent (5%) of the total intended purchase amount will be held in escrow in
shares registered in the investor's name. Shares held in escrow under a Letter
of Intent are not eligible for the exchange privilege until the Letter of Intent
is completed or canceled. A Letter of Intent does not represent a binding
obligation on the part of the investor to purchase or the funds to sell the full
amount of shares specified.
    
 
   
CLASS B WAIVERS OF CONTINGENT DEFERRED SALES CHARGES
    
 
   
The CDSC will be waived on the following redemptions of Class B shares:
    
 
   
(1) 10% FREE AMOUNT. We waive the CDSC on redemptions of Class B shares of up to
    10% per year of the amount initially invested in Class B shares. (Remember
    that the CDSC does not apply to appreciation and reinvested dividends.
    Redemptions from appreciation and reinvested dividends, which occur first,
    do not count toward the 10% free amount.)
    
 
   
(2) DEATH OR DISABILITY. We waive the CDSC on redemptions of Class B shares
    following the shareholder's death or disability, so long as:
    
 
   
    (a) SM&R is notified of such death or disability at the time of the
        redemption request and receives satisfactory evidence of such death or
        disability;
    
 
   
    (b) the redemptions are made within one year following death or initial
        determination of disability; and
    
 
   
    (c) the shares were held at the time of death or initial determination of
        disability.
    
 
   
    For purposes of this waiver, the death or disability must meet the
    definition in Section 72(m)(7) of the Internal Revenue Code (the "Code"). If
    the shares are held in a joint account, then all registered joint owners
    must be dead or disabled.
    
 
   
(3) MINIMUM REQUIRED DISTRIBUTIONS. We waive the CDSC on redemptions of Class B
    shares in connection with certain distributions from three types of
    qualified retirement plans: IRAs, custodial accounts maintained pursuant to
    Code Section 403(b),
    
 
                                       22
<PAGE>
   
    and plans qualified under Code Section 401. To qualify for the waiver, the
    redemptions must result from one of the following:
    
 
   
    (a) required minimum distributions to plan participants or beneficiaries who
        are age 70 1/2 or older;
    
 
   
    (b) in kind transfers of assets where the participant or beneficiary
        notifies SM&R of such transfer before such transfer occurs;
    
 
   
    (c) tax-free rollovers or transfers of assets to another IRA, Section 403(b)
        plan, or Section 401 plan invested in Class B shares of one or more
        funds managed by SM&R;
    
 
   
    (d) tax-free returns of excess contributions or returns of excess deferral
        amounts; and
    
 
   
    (e) distributions upon the death or disability (as defined in the Code) of
        the participant or beneficiary.
    
 
   
DISTRIBUTION AND SHAREHOLDER SERVICE (12b-1) FEE
    
 
   
Classes A, B, and C pay SM&R, the principal underwriter, a distribution and/or
shareholder servicing (12b-1) fee. BECAUSE DISTRIBUTION AND/OR SHAREHOLDER
SERVICING (12b-1) FEES ARE PAID OUT OF FUND ASSETS ON AN ONGOING BASIS, THE FEES
MAY, OVER TIME, INCREASE THE COST OF AN INVESTMENT IN A FUND AND COST INVESTORS
MORE THAN OTHER TYPES OF SALES LOADS.
    
 
   
These fees are computed as an annual percentage of the average daily net assets
of each class of shares of a fund, as follows:

INVESTMENT OBJECTIVES AND POLICIES
    
- -------------------------------------------------------------------
 
   
Each fund pursues its own investment objective through various investment
policies and techniques. ONLY THE PRINCIPAL INVESTMENT STRATEGIES OF EACH FUND
AND THE PRINCIPAL TYPES OF SECURITIES EACH FUND PLANS TO PURCHASE ARE DESCRIBED
BELOW. These policies and techniques are not fundamental and may be changed by
the Board of Directors without shareholder approval.
    
 
   
Because of the market risks inherent in any investment, the funds may not
achieve their investment objectives. In addition, effective management of each
fund is subject to general economic conditions and to the ability and investment
techniques of management. The net asset value of each fund's shares will vary
and the redemption value of shares may be either higher or lower than the
shareholder's cost. Since each fund has a different investment objective, each
will have different investment results and incur different market, financial,
and other risks.
    
 
   
GOVERNMENT BOND FUND
(FORMERLY NAMED AMERICAN NATIONAL GOVERNMENT INCOME FUND SERIES)
    
 
   
The Government Bond Fund seeks to achieve its objective through investment of
65% or more of its total assets in securities issued or guaranteed by the U.S.
Government, its agencies or instrumentalities ("U.S. Government Obligations")
which include, but are not limited to, U.S. Treasury Bonds, Notes and Bills and
securities issued by instrumentalities of the U.S. Government.
    
 
   
U.S. GOVERNMENT OBLIGATIONS--There are two broad categories of U.S. Government
Obligations:
    
 
   
(1) direct obligations of the U.S. Treasury, and
    
 
   
(2) obligations issued or guaranteed by agencies or instrumentalities of the
    U.S. Government.
    
 
   
Some obligations issued or guaranteed by agencies or instrumentalities of the
U.S. Government are backed by the full faith and credit of the United States
(such as Government National Mortgage Association Certificates); others, by the
agency or instrumentality with limited rights of the issuer to borrow from the
U.S. Treasury (such as Federal National Mortgage Association Bonds); and others,
only by the credit of the issuer. No assurance can be given that the U.S.
    
 
                                       24
<PAGE>
   
Government would lend money to or otherwise provide financial support to U.S.
Government sponsored instrumentalities; it is not obligated by law to do so.
    
 
   
MORTGAGE-BACKED SECURITIES--We anticipate that a substantial portion of the
Government Bond Fund's portfolio will consist of mortgage-backed securities
issued or guaranteed by the U.S. Government, its agencies, or instrumentalities.
These securities represent part ownership of pools of mortgage loans secured by
real property, such as certificates issued by the Government National Mortgage
Association ("GNMA" or "Ginnie Mae"), the Federal National Mortgage Association
("FNMA" or "Fannie Mae"), and the Federal Home Loan Mortgage Corporation
("FHLMC" or "Freddie Mac"). Mortgage-backed securities also include mortgage
pass-through certificates representing participation interests in pools of
mortgage loans originated by the U.S. Government and guaranteed by U.S.
Government agencies such as GNMA, FNMA, or FHLMC. Such certificates, which are
ownership interests in the underlying mortgage loans, differ from conventional
debt securities which provide for periodic payment of interest in fixed amounts
and principal payments at maturity or on specified dates. With pass-through
certificates, both principal and interest payments, including prepayments, are
passed through to the holder of the certificate and provide for monthly payments
of interest and principal. GNMA, a federal agency, issues pass-through
certificates that are guaranteed as to timely payment of principal and interest.
FNMA, a federally chartered and privately owned corporation, issues mortgage
pass-through securities and guarantees them as to timely payment of principal
and interest. FHLMC, a corporate instrumentality of the United States, issues
participation certificates that represent an interest in mortgages from FHLMC's
portfolio. FHLMC guarantees the timely payment of interest and the ultimate
collection of principal. FNMA and FHLMC are not backed by the full faith and
credit of the United States, although FNMA and FHLMC are authorized to borrow
from the U.S. Treasury to meet their obligations. Those mentioned are but a few
of the mortgage-backed securities currently available. The Government Bond Fund
will not purchase interest-only or principal-only mortgage-backed securities.
    
 
   
The yield characteristics of mortgage-backed securities differ from traditional
debt securities. Among the major differences are that interest and principal
payments are made more frequently, usually
    
 
                                       25
<PAGE>
   
monthly, and that principal may be prepaid at any time because the underlying
mortgage loans generally may be prepaid at any time. The average mortgage in a
pool may be expected to be repaid within about twelve (12) years. If mortgage
interest rates decrease, the value of the Government Bond Fund's securities will
generally increase. However, we anticipate that the average life of the
mortgages in the pool will decrease as borrowers refinance and prepay mortgages
to take advantage of lower interest rates. The Government Bond Fund invests the
proceeds from such prepayments at the then prevailing lower interest rates. On
the other hand, if interest rates increase, the value of the Fund's securities
generally will decrease while it is anticipated that borrowers will not
refinance and, therefore, the average life of the mortgages in the pool will be
longer. In addition, if the Government Bond Fund purchases such a security at a
premium, a prepayment rate faster than expected will reduce yield to maturity,
while a prepayment rate slower than expected will have the opposite effect of
increasing yield to maturity. Conversely, if the Government Bond Fund purchases
these securities at a discount, faster than expected prepayments will increase
yield to maturity, while slower than expected prepayments will reduce yield to
maturity.
    
 
   
COLLATERALIZED MORTGAGE OBLIGATIONS--The Government Bond Fund may invest a
portion of its assets in collateralized mortgage obligations or "CMOs," which
are debt obligations collateralized by a portfolio or pool of mortgages,
mortgage-backed securities, or U.S. Government securities. Collateralized
obligations in which the Government Bond Fund may invest are issued or
guaranteed by a U.S. Government agency or instrumentality, such as the FHLMC. A
variety of types of collateralized obligations are currently available and
others may become available in the future. One should keep in mind that during
periods of rapid interest rate fluctuation, the price of a security, such as a
CMO, could either increase or decrease based on inherent interest rate risk.
Additionally, the risk of maturities shortening or lengthening in conjunction
with interest rate movement, could magnify the overall effect of the price
fluctuation.
    
 
   
A CMO is often issued in multiple classes with varying maturities and interest
rates. As a result the investor may obtain greater predictability of maturity
than with direct investments in mortgage-backed securities. Thus, classes with
shorter maturities may have lower volatility and lower yield while those with
longer maturities
    
 
                                       26
<PAGE>
   
may have higher volatility and higher yields. This provides the investor with
greater control over the characteristics of the investment in a changing
interest rate environment. A more complete description of CMOs is contained in
the Statement of Additional Information.
    
 
   
The Government Bond Fund may also invest in parallel pay CMOs and Planned
Amortization Class CMOs ("PAC Bonds"). Parallel pay CMOs are structured to
provide payments of principal on each payment date to more than one class. PAC
Bonds generally require payments of a specified amount of principal on each
payment date. PAC Bonds are always parallel pay CMOs with the required principal
payment on such securities having the highest priority after interest has been
paid to all classes.
    
 
   
The Government Bond Fund may also invest in securities issued by private issuers
that represent an interest in or are secured by mortgage-backed securities
issued or guaranteed by the U.S. government or one of its agencies or
instrumentalities. In addition, the fund may invest in securities issued by
private issuers that represent an interest in or are secured by mortgage loans
or mortgage-backed securities without a government guarantee but usually have
some form of private credit enhancement.
    
 
   
ZERO COUPON BONDS--The Government Bond Fund may invest in zero coupon bonds,
which are debt obligations issued or purchased at a significant discount from
face value. The Government Bond Fund will only purchase zero coupon bonds which
are U.S. Government Obligations. The discount approximates the total amount of
interest the bonds will accrue and compound over the period until maturity or
the first interest payment date at a rate of interest reflecting the market rate
of the security at the time of issuance. Zero coupon bonds do not entitle the
holder to any periodic payments of interest prior to maturity. Its value as an
investment consists of the difference between its face value at the time of
maturity and the price for which it was acquired which is generally an amount
significantly less than face value (sometimes referred to as a "deep discount"
price). Zero coupon bonds require a higher rate of return to attract investors
who are willing to defer receipt of cash. Accordingly, although not providing
current income, SM&R believes that zero coupon bonds can be effectively used to
lock in a higher rate of return in a declining interest environment. Such
investments may experience greater volatility in market value than debt
obligations which make regular
    
 
                                       27
<PAGE>
   
payments of interest. The Fund will accrue income on such investments for tax
and accounting purposes, as required, which is distributable to shareholders and
which, because no cash is received at the time of accrual, may require the
liquidation of other portfolio securities to satisfy the Fund's distribution
obligations.
    
 
   
TAX FREE FUND (FORMERLY NAMED AMERICAN NATIONAL TAX FREE FUND SERIES)
    
 
   
The Tax Free Fund, as a matter of fundamental policy, seeks to achieve its
objective by investing at least 80% of the value of its net assets in municipal
securities the interest on which is exempt from federal income taxes.
    
 
   
The Tax Free Fund has no restrictions on the maturity of municipal securities in
which it may invest. Accordingly, it will seek to invest in municipal securities
of such maturities which, in the judgement of SM&R, the adviser, will provide a
high level of current income consistent with prudent investment, with
consideration given to market conditions.
    
 
   
The Tax Free Fund will invest, without percentage limitations, in municipal
securities having at the time of purchase one of the four highest municipal
ratings by Moody's Investor Service, Inc. ("Moody's"), Standard & Poor's
Corporation ("S&P"), or Fitch Investors Service (E.G., MIG 4 or higher by
Moody's) or in securities which are not rated, provided that, in the opinion of
SM&R, such securities are comparable in quality to those within the four highest
ratings. The rating agencies consider that bonds rated in the fourth highest
category may have some speculative characteristics and that changes in economic
conditions or other circumstances are more likely to lead to a weakened capacity
to make principal and interest payments on those bonds than is the case with
higher grade bonds. SM&R will only purchase bonds rated in such fourth category
if it believes that the purchase of such bonds is consistent with the Tax Free
Fund's investment objective. In the event the rating of an issue held by the Tax
Free Fund is changed by the rating service, such change will be considered by
the Tax Free Fund in its evaluation of the overall investment merits of that
security but such change will not necessarily result in an automatic sale of the
security. Any security held which is subsequently downgraded below BBB by S&P or
Baa by Moody's will be sold as soon as it is advantageous to do so
    
 
                                       28
<PAGE>
   
after the downgrade. A description of the ratings may be found in the Appendix
to this Prospectus.
    
 
   
Purchasing unrated municipal securities, which may be less liquid than
comparably rated municipal securities, involves somewhat greater risk and
consequently the Tax Free Fund may not invest more than 20% of its net assets in
unrated municipal securities. To attempt to minimize the risk of such
investments, SM&R will, prior to acquiring unrated securities, consider the
terms of the offering and various other factors to determine the issuer's
comparative credit rating and whether the securities are consistent with the Tax
Free Fund's investment objective and policies.
    
 
   
During normal market conditions, the Tax Free Fund will have at least 80% of its
net assets invested in municipal securities the income of which is fully exempt
from federal income taxation. Furthermore, under normal market conditions up to
20% of the Tax Free Fund's net assets, and as a temporary defensive measure
during abnormal market conditions, up to 50% of its net assets may be invested
in the following types of taxable fixed income obligations:
    
 
   
(1) obligations issued or guaranteed by the U.S. government, its agencies,
    instrumentalities or authorities (See "Government Bond Fund" above for an
    explanation of U.S. government obligations);
    
 
   
(2) corporate debt securities which at the date of the investment are rated A or
    higher by Moody's or by S&P;
    
 
   
(3) commercial paper which at the date of the investment is rated in one of the
    two top categories by Moody's or by S&P or if not rated, is issued by a
    company which at the date of the investment has an outstanding debt issue
    rated A or higher by Moody's or A or higher by S&P;
    
 
   
(4) certificates of deposit issued by U.S. banks which at the date of the
    investment have capital surplus and undivided profits of $1 billion as of
    the date of their most recently published financial statements; and
    
 
   
(5) repurchase agreements secured by U.S. government securities, provided that
    no more than 15% of the Fund's net assets will be invested in illiquid
    securities including repurchase agreements with maturities in excess of
    seven days.
    
 
                                       29
<PAGE>
   
To the extent income dividends include income from taxable sources, a portion of
a shareholder's dividend income may be taxable. (See "Dividends, Distributions,
and Taxes"). In addition, Congress could enact tax legislation such as a flat
tax rate that would make tax-free bonds less desirable to investors seeking ways
to reduce taxable income. If that were to occur, it could cause the value of the
securities to drop.
    
 
   
The Tax Free Fund's ability to achieve its objective depends partially on the
prompt payment by issuers of the interest on and principal of the municipal
securities held. A moratorium, default, or other non-payment of interest or
principal when due could, in addition to affecting the market value and
liquidity of the particular security, affect the market value and liquidity of
other municipal securities. Additionally, the market for municipal securities is
often thin and can be temporarily affected by large purchases and sales. As a
result, the Tax Free Fund will attempt to minimize risk by diversifying its
investments by investing no more than 5% of its net assets in the securities of
any one issuer (this limitation does not apply to investments issued or
guaranteed by the U.S. Government or its instrumentalities) and by investing no
more than 25% of its net assets in municipal securities issued in any one state
or territory. Each political subdivision, agency, instrumentality, and each
multi-state agency of which a state is a member will be regarded as a separate
issuer for the purpose of determining diversification.
    
 
   
MUNICIPAL SECURITIES--The term "municipal securities," as used in this
Prospectus means obligations issued by or on behalf of states, territories, and
possessions of the U.S. and the District of Columbia and their political
subdivisions, agencies, and instrumentalities, the interest on which is exempt
from federal income tax. An opinion as to the tax-exempt status of a municipal
security generally is rendered to the issuer by the issuer's counsel at the time
of issuance of the security. Neither the funds nor SM&R will review the
proceedings relating to the issuance of municipal obligations or the basis for
opinions of counsel.
    
 
   
Municipal securities are used to raise money for various public purposes such as
constructing public facilities and making loans to public institutions. Certain
types of municipal bonds are issued to obtain funding for privately operated
facilities. Further information on the maturity and funding classifications of
municipal securities is included in the Statement of Additional Information.
    
 
                                       30
<PAGE>
   
Yields on municipal securities vary, depending on a variety of factors,
including the general condition of the financial markets and of the municipal
securities market, the size of a particular offering, the maturity of the
obligation and the credit rating of the issuer. Like other interest-bearing
securities, the value of municipal securities changes as interest rates
fluctuate. For example, if interest rates increase from the time a security is
purchased, the security's value and sales price generally will be less than its
purchase cost. Conversely, if interest rates decline from the time a security is
purchased, the security's value and sales price may be greater than its purchase
cost. Generally, municipal securities of longer maturities produce higher
current yields than municipal securities with shorter maturities but are subject
to greater price fluctuation due to changes in interest rates, tax laws and
other general market factors. Lower-rated municipal securities generally produce
a higher yield with shorter maturities than higher-rated municipal securities
due to the perception of a greater degree of risk as to the ability of the
issuer to pay principal and interest.
    
 
   
The Tax Free Fund may purchase municipal bonds for which the payments of
principal and interest are secured by an escrow account of securities backed by
the full faith and credit of the U.S. government ("defeased") and municipal
securities whose principal and interest payments are insured by a commercial
insurance company as long as the underlying credit is investment grade (BBB or
better by S&P and Fitch and Baa or better by Moody's) ("insured"). The Tax Free
Fund may also purchase unrated securities of issuers which SM&R believes would
have been rated BBB or Baa had the issuer requested a rating from S&P, Fitch or
Moody's. Such implied investment grade rating will be determined by SM&R upon
its performance of a credit analysis of the issue and the issuer. Such credit
analysis may consist of a review of such items as the issuer's debt
characteristics, financial information, structure of the issue, liquidity of the
issue, quality of the issuer, current economic climate, financial adviser, and
underwriter. Insured and defeased bonds are further described in the Statement
of Additional Information. In general, these types of municipal securities will
not be treated as an obligation of the original municipality for purposes of
determining industry concentration.

PRIMARY FUND (FORMERLY NAMED AMERICAN NATIONAL PRIMARY FUND SERIES)
    
 
   
Commercial paper is short-term unsecured promissory notes issued by corporations
to finance short-term credit needs. Commercial paper is usually sold on a
discount basis and has a maturity at the time of issuance not exceeding nine
months. The Primary Fund will invest only in commercial paper which, at the date
of such investment, is rated in one of the two top categories by one or more of
the nationally recognized statistical rating organizations ("NRSROs") (See the
"Appendix" hereto for information about such ratings and such rating
organizations).
    
 
   
The Primary Fund, consistent with its investment objective, will attempt to
maximize yield by trying to take advantage of changing conditions and trends. It
may also attempt to take advantage of what are believed to be disparities in
yield relationships between different instruments. This procedure may increase
or decrease the portfolio yield depending upon the Primary Fund's ability to
correctly time and execute such transactions. Although the Primary Fund's assets
will be invested in securities with short maturities, the Primary Fund will
manage its portfolio as described above. (See "Portfolio Transactions and
Brokerage Allocation" in the Statement of Additional Information.)
    
 
   
OTHER INVESTMENTS--The Primary Fund may invest in (i) U.S. Government
Obligations (See the "Government Bond Fund" above for an explanation of U.S.
Government Obligations); (ii) other corporate obligations, such as bonds,
debentures or notes maturing in five (5) years or less at the time of purchase
which at the date of the investment are rated "A" or higher by an NRSRO; and
(iii) negotiable certificates of deposit of banks (including U.S. dollar
denominated obligations of foreign branches of U.S. banks and U.S. branches of
foreign banks and savings and loan associations and banker's acceptances of U.S.
banks which banks and savings and loan associations have total assets at the
date of investment (as of the date of their most recent published financial
statements) of at least $1 billion (See "INVESTMENT OBJECTIVES AND POLICIES-
Certificates of Deposit" in the Statement of Additional Information for a
description of the securities) and (iv) repurchase agreements with respect to
any type of instrument in which the Primary Fund is authorized to invest even
though the underlying instrument may mature in more than two (2) years.

MONEY MARKET FUND
    
 
   
The Money Market Fund seeks to achieve its objective by investing in short-term
money market instruments determined to be of high quality by SM&R pursuant to
guidelines established by the Company's Board of Directors. The Money Market
Fund may invest in the following types of high quality debt obligations:
    
 
   
(1) U.S. GOVERNMENT OBLIGATIONS. U.S. Government Obligations consist of
marketable securities issued or guaranteed as to both principal and interest by
the United States Government or by its agencies and instrumentalities. (See
"Government Bond Fund" above for an explanation of U.S. Government Obligations).
    
 
   
(2) CERTIFICATES OF DEPOSIT. Certificates of deposit are negotiable certificates
issued against funds deposited in a commercial bank for a definite period of
time and earning a specified return. The Money Market Fund will invest only in
certificates of deposit of U.S. banks that have total assets in excess of $1
billion at the time of investment.
    
 
   
(3) BANKER'S ACCEPTANCES. Banker's acceptances are short-term instruments issued
by banks, generally for the purpose of financing imports or exports. An
acceptance is a time draft drawn on a bank by the importer or exporter to obtain
a stated amount of funds to pay for specific merchandise. The draft is then
"accepted" and is an irrevocable obligation of the issuing bank.
    
 
   
(4) COMMERCIAL PAPER. As discussed above under "Primary Fund," commercial paper
is short-term unsecured promissory notes issued by corporations to finance
short-term credit needs.
    
 
   
(5) BONDS AND NOTES. The Money Market Fund may invest in corporate bonds or
notes with a remaining maturity of one year or less.
    
 
   
(6) COLLATERALIZED MORTGAGE OBLIGATIONS As discussed above under "Government
Bond Fund," CMOs are debt obligations collateralized by a portfolio or pool of
mortgages, mortgage-backed securities, or U.S. Government securities.
    
 
   
The Money Market Fund does not currently intend to invest in unrated securities,
securities subject to demand features, floating rate instruments, securities
subject to guarantees, and variable rate instruments.
    
 
                                       33
<PAGE>
   
The Money Market Fund limits its investments to those short-term securities that
the Board determines present minimal credit risk and that are "Eligible
Securities" when acquired by the Fund. As used in this Prospectus, "Eligible
Securities" means securities that are:
    
 
   
(a) rated in one of the two highest short-term rating categories, or
    
 
   
(b) whose issuer has another class of debt obligations rated in one of the two
    highest short-term rating categories.
    
 
   
To rely on a rating assigned to other debt obligations, those obligations must
be of comparable priority and security. All ratings must have been issued by the
requisite NRSROs. Currently, five organizations are NRSROs: Moody's, S&P, Fitch
Investors Service, Inc., Duff and Phelps, Inc., and Thomson BankWatch, Inc. A
discussion of the ratings categories of S&P and Moody's is contained in the
Appendix.
    
 
   
The Money Market Fund generally limits its investments in securities, as
follows:
    
 
   
  - It will not invest in securities issued by any one issuer, other than the
    U.S. Government, its agencies, or instrumentalities, in an amount that
    exceeds 5% of its total assets.
    
 
   
  - It will not invest more than 5% of its total assets in securities relying on
    ratings in the second highest rating category.
    
 
   
  - It will not invest more than 1% of its total assets in securities of any one
    issuer that rely on ratings in the second highest rating category.
    
 
   
(See "Investment Objectives and Policies" in the Statement of Additional
Information for a more detailed explanation of the investment categories.) The
Fund will maintain a dollar-weighted average portfolio maturity of 90 days or
less, and will not invest in any security with a remaining maturity of over 397
days (13 months).
    
 
   
Investments in money market instruments are subject to the ability of the issuer
to make payment at maturity. In addition, the Money Market Fund's performance
will vary depending on changes in short-term interest rates. However, both the
financial and market risks of investment in the Money Market Fund may be
expected to be less than for any other Fund. By limiting its investments to
Eligible Securities, the Money Market Fund may not achieve as high a level of
current income as a fund investing in lower-rated securities.

RISK FACTORS
    
- -------------------------------------------------------------------
 
   
The following discussion relates to all four funds. The risk/return summary
located at the beginning of this prospectus identifies some specific risks
applicable to each individual fund.
    
 
   
GENERAL. There is no assurance that a fund will achieve its goals. Generally, if
the securities owned by a fund increase in value, the value of the shares of the
fund which you own will increase. Similarly, if the securities owned by a fund
decrease in value, the value of your shares will also go down. In this way, you
participate in any change in the value of the securities owned by a fund.
    
 
   
The risk inherent in investing in any fund is a risk common to any security.
That is, the value of a fund's shares will fluctuate in response to changes in
economic conditions, interest rates and the market's perception of the
underlying portfolio securities held by that fund. Each fund's share value
depends on general economic and securities market conditions, the investment
decisions of its management, and numerous other factors. All of these factors
are inherently uncertain and, in some cases, unforeseeable.
    
 
   
Any of the funds could lose money if the stock markets in general go down or if
the particular debt obligations purchased by a fund go down in value. In
addition, the funds could lose money if prevailing interest rates increase or if
the debt securities purchased by a fund are downgraded or defaulted upon.
    
 
   
DEBT SECURITIES RISKS. Debt securities are subject to change in their values due
to changes in prevailing interest rates. The magnitude of these fluctuations
will often be greater for longer-term debt securities than shorter-term debt
securities. When prevailing interest rates fall, the values of already-issued
debt securities generally rise. Accordingly, if interest rates go down after a
security is purchased, such security might be valued and/or sold at a price
greater than its cost. If interest rates were to drop dramatically, some of the
securities could be called and/or prepaid, requiring reinvesting in securities
at much lower yields.
    
 
   
On the other hand, when prevailing interest rates rise, the values of
already-issued debt securities generally fall. Accordingly, if interest rates
increase after a security is purchased, such security might be valued and/or
sold at a price less than its cost. In such circumstances,
    
 
                                       35
<PAGE>
   
the value of existing bonds decrease because the interest payments from existing
bonds are less attractive than new issues with higher interest rates and
investors would lose money if they liquidate holdings.
    
 
   
The funds could lose money if any bonds they own are downgraded in credit rating
or go into default. A moratorium, default, or other non-payment of interest or
principal when due could, in addition to affecting the market value and
liquidity of the particular security, affect the market value and liquidity of
other securities. A change in credit rating of an issuer can also affect the
bond's value, thus affecting the market value of the funds. However, the funds
invest predominately in investment grade bonds in order to minimize credit risk.
(See "Investment Objectives and Policies" for more information about the ratings
required for investments by each specific fund.) Moreover, substantial
redemptions of fund shares could require a fund to sell portfolio securities at
a time when a sale might not be favorable.
    
 
   
U.S. GOVERNMENT OBLIGATIONS. Investments in U.S. Government Obligations are not
all backed by the "full faith and credit" of the United States Government. Some
are backed only by the rights of the issuer to borrow from the U.S. Treasury and
others are supported only by the credit of the issuing instrumentality. No
assurance can be given that the U.S. Government would lend money to or otherwise
provide financial support to U.S. Government sponsored instrumentalities.
    
 
   
MARKET RISKS. Because the funds may invest in debt obligations which are traded
on securities exchanges, the value of each fund's portfolio will be affected by
changes in the stock markets. At times, the stock markets can be volatile and
stock prices can change substantially. This market risk will affect each fund's
net asset value per share, which will fluctuate as the values of each fund's
portfolio securities change. Prices do not always change uniformly or at the
same time and the various stock markets do not always move in the same direction
at the same time. Other factors specific to a particular company also affect the
price of that company's debt obligations (for example, poor earnings, loss of
major customers, or major litigation). The funds cannot always predict the
factors that will affect a security's price. The funds, however, do attempt to
limit market risk by diversifying their investments. The funds diversify their
investments by generally investing only a small percentage of their assets in
the debt
    
 
                                       36
<PAGE>
   
obligations of any one company and by not holding a substantial amount of the
debt obligations of any one company.
    
 
   
REPURCHASE AGREEMENTS. In a repurchase agreement, a fund buys a security and
simultaneously sells it to the vendor for delivery at a future date. These
agreements are used primarily for cash purposes. A fund entering into a
repurchase agreement may lose money if the other party to the transaction fails
to pay the resale price on the delivery date. Such a default may delay or
prevent the fund from disposing of the underlying securities. The value of the
underlying securities may go down during the period in which the fund seeks to
dispose of them. Also, the fund may incur expenses while trying to sell the
underlying securities. Finally, the fund risks losing all or a part of the
income from the agreement.
    
 
   
OTHER RISKS. Each investor will be subject to all the risks normally attendant
to business operations, changes in general economic conditions, governmental
rules and fiscal policies, acts of God, and other factors beyond the control of
the funds' management.
    
 
   
YEAR 2000 RISKS. Many services provided to the funds and their shareholders
depend on the smooth functioning of computer systems. Many computer software
systems in use today cannot distinguish the year 2000 from the year 1900 because
of the way dates are encoded and calculated, referred to as the "Year 2000
Problem." The Year 2000 Problem could have a negative impact on handling
securities trades, payment of interest and dividends, pricing, and account
services. Like other mutual funds, financial and business organizations, and
individuals around the world, the funds could be adversely affected if the
computer systems used by SM&R (which acts as their investment adviser,
underwriter, custodian, and transfer agent) do not properly process and
calculate date-related information and data from and after January 1, 2000. SM&R
is taking steps to address the Year 2000 Problem with respect to the computer
systems that it uses and to obtain assurances that comparable steps are being
taken by any other service providers. At this time, however, there can be no
assurance that these steps will be sufficient to avoid any adverse impact on the
funds and their shareholders.

PURCHASES AND REDEMPTIONS
    
- -------------------------------------------------------------------
   
PURCHASING SHARES
    
 
   
You may purchase shares of a fund from registered representatives of SM&R, from
authorized broker-dealers, or directly from SM&R. Such purchases will be at the
offering price for such shares determined as and when provided below (See
"Pricing of Fund Shares"). SM&R will send you a monthly confirmation for any
month in which your account is active. You should carefully review the monthly
confirmation and promptly report any discrepancies to SM&R. You may make initial
and subsequent purchases directly through SM&R at the following address:
    
 
   
    Securities Management and Research, Inc.
    2450 South Shore Boulevard, Suite 400
    League City, Texas 77573
    
 
   
Certificates are not normally issued for shares of the funds in an effort to
minimize the risk of loss or theft. SM&R confirms investors' purchases and
credits such purchases to their accounts on the books maintained by SM&R.
Investors have the same rights of share ownership as they would if certificates
had been issued. Furthermore, a lost, stolen or destroyed certificate cannot be
replaced without obtaining a sufficient indemnity bond. The cost of such a bond
is borne by the investor and can be 2% or more of the value of the lost, stolen
or destroyed certificate.
    
 
   
OPENING AN ACCOUNT: To purchase shares, you must submit an account application
which includes the purchaser suitability form. If you would like to take
advantage of the electronic services available, please complete the electronic
transfer options section of the account application. Special forms are required
when establishing an IRA/ SEP or 403(b) plan. Please call Investor Services at
(800) 231-4639 and request special forms when establishing retirement plans.
    
 
   
MINIMUM PURCHASE REQUIREMENT: The minimum initial investment requirement is $100
for the Government Bond and Tax Free Funds, and $1000 for the Money Market and
Primary Funds. The minimum amount of any subsequent purchase is $20 for the
Government Bond and Tax Free Funds, and $100 for the Money Market and Primary
Funds. We waive these initial investment minimums when purchases are part of
certain systematic investment programs (See "Special
    
 
                                       38
<PAGE>
   
Purchase Plans and Services" for additional information on reduction of the
minimums). We reserve the right to reject any purchase.
    
 
   
PURCHASES BY MAIL: Make your check(s) payable to SM&R and send the check(s) to
the address indicated above. Please note that third party checks will not be
accepted to open a new account, except for IRA rollover checks that are properly
endorsed. If you make subsequent investments by mail, you must indicate your
name, account number, and the name of the class and the fund being purchased.
You may use the remittance slip attached to the confirmation statement.
    
 
   
PURCHASES BY WIRE: TO ENSURE PROPER CREDITING OF A WIRE INVESTMENT, YOU MUST
HAVE AN EXECUTED ACCOUNT APPLICATION AND PURCHASER SUITABILITY FORM ON FILE WITH
THE TRANSFER AGENT. You may then wire your investment to The Moody National Bank
of Galveston ("Moody National Bank") by providing the following instructions to
your bank:
    
 
   
    The Moody National Bank of Galveston ABA #113100091
    Securities Management and Research, Inc. #035 868 9
    Name of Class and Fund (E.G., Class A of the Government Bond Fund)
    Fund Account Number (number appears on your confirmation statement)
    Your Name (E.G., Mary Smith)
    
 
   
PURCHASES BY EXCHANGE: Call Investor Services if you have established telephone
exchange privileges on your account. See "Special Purchase Plans and
Services--Exchange Privilege" for procedures and additional information relating
to telephone exchanges. For limitations on exchanges, see "Excessive Trading"
also under "Special Purchase Plans and Services."
    
 
   
PRICING OF FUND SHARES
    
 
   
GENERAL (HOW SHARES ARE PRICED). We determine each fund's offering price once
each business day. The offering price equals a fund's net asset value plus the
sales charge, if any, computed at the rate set forth in the applicable tables
for the classes. (See "Shares of the Funds--Sales Charges.") You may purchase
shares of the Primary and Money Market Funds without a sales charge.
Accordingly, the offering price for shares of the Primary and Money Market Funds
is net asset value.
    
 
                                       39
<PAGE>
   
Although the legal rights of the Class A, B, and C shares are substantially
identical, the different expenses borne by each class will result in different
net asset values and dividends. The net asset value of the Class B and C shares
generally will be lower than the Class A shares as a result of respective
service and distribution (12b-1) fees charged.
    
 
   
EFFECTIVE DATE OF PURCHASES AND REDEMPTIONS (WHEN SHARES ARE PRICED).
Calculation of net asset value is made once each business day at the close of
the New York Stock Exchange (currently 3:00 p.m. Central Time). Accordingly, the
price you pay or receive for shares of a fund depends, in part, on the day and
time you make your purchase or redemption. On any business day, we will execute
purchases and redemptions at the applicable price determined that day if:
    
 
   
  - SM&R receives your order in proper form prior to the close of the Exchange;
    
 
   
  - a securities dealer having a dealer contract with SM&R receives your order
    prior to the close of the Exchange and reports your order to SM&R prior to
    SM&R's close of business (currently 4:30 p.m. Central Time) on the same day;
    or
    
 
   
  - for purchases, Moody National Bank receives your purchase payment by bank
    wire and reports it to SM&R prior to the close of the Exchange.
    
 
   
If we receive your order after the close of the Exchange, on customary national
business holidays, or on an SM&R business holiday, we will execute your purchase
or redemption at the price determined on the next business day. In unusual
circumstances, any fund may temporarily suspend the processing of sell requests,
or may postpone payment of proceeds for up to three business days or longer, as
allowed by federal securities laws.
    
 
   
SM&R BUSINESS HOLIDAYS. SM&R's business holidays are:
    
 
   
  - Good Friday
    
 
   
  - Memorial Day
    
 
   
  - Independence Day
    
 
   
  - Labor Day
    
 
   
  - Thanksgiving Day
    
 
   
  - the day after Thanksgiving
    
 
   
  - Christmas Day
    
 
   
  - New Years Day
    
 
   
In addition, SM&R business holidays include the weekday preceding Christmas Day,
or, if Christmas Day is a Saturday, the preceding
    
 
                                       40
<PAGE>
   
Thursday and Friday. If Christmas Day is a Sunday, the following Monday also
will be a business holiday. If New Years Day is a Saturday, the preceding Friday
will be a business holiday, and if New Years Day is a Sunday, the following
Monday will be a business holiday.
    
 
   
SPECIAL PURCHASE PLANS AND SERVICES
    
 
   
In addition to the special plans described above, that permit you to reduce the
initial sales charge assessed on Class A shares or the CDSC on Class B shares,
the Company offers other services and plans that are designed to facilitate
investment in the funds. At this time, there is no charge to you for these
services. The Company may impose fees for such services in the future. Be aware,
however, that if you elect to participate in the ACH plan described below, you
should check with your financial institution for any additional charges imposed
for this service. For additional information contact your registered
representative or SM&R. A shareholder considering any of the plans or services
described below should consult a tax advisor before beginning a plan.
    
 
   
ELECTRONIC TRANSFERS (ACH). The electronic transfer option allows you to move
money between your account(s) and your bank, savings and loan, or credit union
account using the Automated Clearing House ("ACH") network. To arrange for
electronic transfers, complete the relevant section of the account application
at the time you open your account and specify the type of service or services
desired. Attach a voided, pre-printed check or deposit slip from your checking,
savings and loan, or credit union account. PASSBOOK SAVINGS ACCOUNTS ARE NOT
ELIGIBLE FOR THE ELECTRONIC TRANSFER OPTION. ADDITIONALLY, YOUR BANK MUST BE A
MEMBER OF THE AUTOMATED CLEARING HOUSE (ACH) NETWORK FOR YOU TO TAKE ADVANTAGE
OF THIS SERVICE. You will receive a confirmation verifying initialization of the
electronic transfer option and may begin conducting transactions in your
account(s) under this option approximately 20 calendar days after receipt of the
verification notice from SM&R. If you elect this option after your account is
established, it may be necessary for you to obtain a signature guarantee for all
individuals named on the account(s).
    
 
   
TELEPHONE SERVICES. You can take advantage of this service by completing the
appropriate sections of the account application when opening your account.
Through this service, you will be able to purchase by ACH, redeem and exchange
shares on those accounts
    
 
                                       41
<PAGE>
   
for which you have an executed account application on file, and have received
written verification from SM&R that the service has been initialized as
explained under Electronic Transfers above. If this option is elected after your
account is established, it may be necessary for you to obtain a signature
guarantee for all individuals named on the account(s). We permit transfers by
telephone from a joint account only to another joint account registered in the
identical names. There may be additional restrictions on telephone transactions
by joint account owners. Contact your registered representative for more
information. PLEASE NOTE THAT THE TELEPHONE REDEMPTION OPTION IS NOT AVAILABLE
TO RETIREMENT PLANS.
    
 
   
The funds have implemented the following security procedures intended to protect
your account from losses resulting from unauthorized or fraudulent telephone
instructions: The caller must know:
    
 
   
 (i) the name of the fund or funds;
    
   
 (ii) all digits of the account number;
    
   
(iii) the exact name and address used in the registration(s); and
    
   
 (iv) the Social Security or Employer Identification Number listed on the
      account(s).
    
 
   
Additionally, we record all telephone transactions for your protection.
    
 
   
Neither the funds nor SM&R will be responsible for the authenticity of
transaction instructions received by telephone which comply with the current
security procedures and other requirements. SM&R believes that such security
procedures and other requirements are reasonable and, if followed, you should
bear the risk of any losses resulting from unauthorized or fraudulent telephone
transactions on your account(s).
    
 
   
AUTOMATIC INVESTMENT PLAN. Through this plan, a specified amount is
electronically transferred (via ACH) from your bank account and invested
monthly, bi-monthly, quarterly, or annually into the designated fund(s) at the
applicable offering price determined on the date of the electronic transfer.
    
 
   
GROUP SYSTEMATIC INVESTMENT PLAN. SM&R can establish a Group Systematic
Investment Plan with an employer having 5 or more participants under a single
payroll deduction arrangement. We waive the minimum initial investment amount
requirement per account for
    
 
                                       42
<PAGE>
   
such plans. However, all other investment amount minimums apply. Contact SM&R
for further information regarding such plans.
    
 
   
WEALTH ACCUMULATION ACCOUNT. Shareholders having account balances of at least
$2,500 in the Money Market Fund may open a Wealth Accumulation Account, which
will provide them with an automatic dollar cost averaging plan. Automatic
monthly purchases of the shares of other funds managed by SM&R may be made by
exchanges from the shareholder's Money Market Fund Wealth Accumulation Account.
Purchases of the other funds must be at least $50 and, unless terminated by the
shareholder, will continue as long as the balance of the Money Market Fund
Wealth Accumulation Account is sufficient. Additional investments may be made to
a Money Market Fund account designated as a Wealth Accumulation Account to
extend the purchase period under the plan. However, if additional investments
are received by SM&R less than ten (10) business days prior to the 20th of the
month, such investments will not be available for use under the Wealth
Accumulation Account until the 20th of the following month. If the 20th of the
month is an SM&R holiday, the purchase will be processed on the next business
day.
    
 
   
Purchases made will be subject to the applicable sales charge of the fund whose
shares are being purchased. Changes in amounts to be purchased, the funds being
purchased, and termination of a Wealth Accumulation Account will be made within
five (5) business days after written instructions are received by SM&R in proper
form (I.E., signed by the owner(s) of record exactly as registered).
    
 
   
Shareholders' rights to make additional investments, to exchange shares, and to
redeem shares in the Money Market Fund and any of the funds managed by SM&R are
not affected by a shareholder's participation in a Wealth Accumulation Account.
However, check writing privileges and expedited redemption by telephone are not
available for the Money Market Fund accounts designated as a part of the Wealth
Accumulation Account.
    
 
   
Primary Fund shareholders that opened a Primary Fund Wealth Accumulation Account
prior to December 31, 1998 will be permitted to continue using the Account
subject to the terms applicable to a Money Market Fund Wealth Accumulation
Account, described above.
    
 
   
EXCHANGE PRIVILEGE. As an investor in a fund, you are permitted to exchange
shares that you own in a fund with shares of another fund
    
 
                                       43
<PAGE>
   
managed by SM&R without the payment of an exchange fee, subject to certain
conditions. EXCHANGES BETWEEN A FUND AND ANOTHER FUND MANAGED BY SM&R ARE
AVAILABLE ONLY IN STATES WHERE THE APPLICABLE FUNDS ARE REGISTERED AND THE
EXCHANGE MAY BE LEGALLY MADE. YOU SHOULD CONTACT SM&R TO DETERMINE WHETHER A
FUND IS REGISTERED IN A PARTICULAR STATE.
    
 
   
GOVERNMENT BOND FUND AND TAX FREE FUND. You may exchange Class A, Class B, or
Class C shares that you own in the Government Bond or Tax Free Fund, without an
exchange fee, for shares of the corresponding class of another fund managed by
SM&R. You also may exchange your Class A, Class B, or Class C shares for shares
of the Primary or Money Market Fund, subject to two conditions:
    
 
   
  - any applicable CDSC period has expired on the shares you wish to exchange
    (I.E., 13 months in the case of Class A and Class C shares and 3 years in
    the case of Class B shares), and
    
 
   
  - you meet any minimum investment requirement for the shares you wish to
    acquire.
    
 
   
Finally, you may exchange shares you own in any class of the Government Bond or
Tax Free Fund for shares of another class of that fund, provided that you pay
any difference in sales charges and any applicable CDSC period has expired on
the shares you wish to exchange.
    
 
   
PRIMARY FUND AND MONEY MARKET FUND. You may exchange shares you own in the
Primary Fund for shares of the Money Market Fund, and vise versa. You may
exchange shares you own in the Primary or Money Market Fund for shares of a
class of another fund managed by SM&R, provided you pay any sales charge
applicable to the acquired shares.
    
 
   
You may acquire, through an exchange, shares of a class with a CDSC. If you
redeem those shares, the relevant CDSC, if any, will be calculated from the date
that you initially purchased the original shares, rather than from the date of
exchange.
    
 
   
Shares of any fund managed by SM&R held in escrow under a Letter of Intent are
not eligible for the exchange privilege. Such shares will not be released from
escrow until the balance invested during the period specified in the Letter of
Intent equals or exceeds the amount required to be invested under the Letter of
Intent or the shareholder requests, in writing, that the Letter of Intent be
canceled
    
 
                                       44
<PAGE>
   
and pays any adjustments in sales charge. After release from escrow, shares may
be exchanged, provided all other applicable conditions are met.
    
 
   
You may request an exchange by telephone or in writing. In order to exchange
shares, the following requirements must be met:
    
 
   
(a) the exchange must be made between accounts having identical registrations
    and addresses;
    
 
   
(b) the shares of the fund acquired through exchange must be qualified for sale
    in the state in which you reside;
    
 
   
(c) the dollar amount of the exchange must meet the minimum investment
    requirement applicable to the shares of the fund that you would acquire
    through the exchange;
    
 
   
(d) SM&R must have received full payment for the shares being exchanged;
    
 
   
(e) your account must have been coded to reflect your certified taxpayer
    identification number, or, if applicable, an appropriate Internal Revenue
    Service Form W-8 (certificate of foreign status) or Form W-9 (certifying
    exempt status);
    
 
   
(f) any shares that you wish to exchange must have been held for at least ten
    (10) business days;
    
 
   
(g) certificates representing shares, if any, are returned before such shares
    are exchanged; and
    
 
   
(h) you have received a prospectus for the shares you receive in the exchange.
    
 
   
The exchange privilege is not an option or right to purchase shares but is
permitted under the respective policies of the participating funds, and may be
modified or discontinued by the participating funds or by SM&R at any time. ANY
GAIN OR LOSS REALIZED ON AN EXCHANGE OR RE-EXCHANGE MAY BE RECOGNIZED FOR
FEDERAL AND STATE INCOME TAX PURPOSES. YOU SHOULD CONSULT YOUR TAX ADVISOR FOR
THE TAX TREATMENT AND EFFECT OF EXCHANGES.
    
 
   
AUTOMATIC CONVERSIONS. Class B shares convert automatically to the appropriate
number of Class A shares of equal dollar value after the investor has owned the
Class B shares for eight (8) years. Dividends and other distributions paid to an
investor in the form of additional Class B shares also convert to Class A shares
on a pro-rata basis.
    
 
                                       45
<PAGE>
   
The conversion benefits shareholders because Class A shares are subject to a
lower ongoing 12b-1 fee. If an investor converts Class B shares of a fund for
Class B shares of another fund managed by SM&R, the purchase date of the
original investment will be used to determine the appropriate conversion date.
    
 
   
EXCESSIVE TRADING. Frequent trades, involving either substantial fund assets or
a substantial portion of your account or accounts controlled by you, can disrupt
management of the Company and raise the Company's expenses. We currently define
"excessive trading" as exceeding one purchase and sale involving the same fund
within any 120-day period.
    
 
   
For example, you are in Fund X. You can move substantial assets from Fund X to
Fund Y and, within the next 120 days, sell your shares in Fund Y to return to
Fund X or move to Fund Z. If you exceed the number of trades described above,
you may be barred indefinitely from further transactions between the
participating funds.
    
 
   
There are two types of transactions exempted from the excessive trading
guidelines. They are (1) redemptions that are not part of exchanges and (2)
systematic purchases or redemptions.
    
 
   
RETIREMENT PLANS
    
 
   
The following retirement plans may be funded with shares of the Government Bond,
Primary, and Money Market Funds:
    
 
   
  - Individual Retirement Accounts (IRAs), which include traditional IRAs, Roth
    IRAs, Education IRAs, and SIMPLE IRAs,
    
 
   
  - Simplified Employee Pension Plans (SEPs),
    
 
   
  - 403(b) Custodial Accounts (TSAs), and
    
 
   
  - corporate retirement plans.
    
 
   
These plans allow you to shelter investment income from federal income tax while
saving for retirement. Information concerning IRAs and TSAs, and the forms
necessary to adopt such plans, can be obtained by contacting your registered
representative or calling SM&R. A regular fund application should be used when
establishing a corporate retirement plan. In connection with retirement plans,
the minimum initial purchase for each fund is $100. The minimum subsequent
purchase is $20 for the Government Bond Fund and $100 for the Money Market and
Primary Funds. SM&R acts as trustee or
    
 
                                       46
<PAGE>
   
custodian for IRAs, SEPs, and TSAs for the Company. An annual custodial fee of
$7.50 per account will be charged for any part of a calendar year in which an
investor has an IRA, SEP, or TSA in the Company and will be automatically
deducted from each account. An individual considering a retirement plan may wish
to consult with an attorney or tax adviser.
    
 
   
Because IRAs, SEPs, TSAs, and other qualified plans are exempt from federal
income tax, they will be unable to benefit from the general tax-exempt nature of
the Tax Free Fund. Accordingly, the Tax Free Fund is not generally considered to
be suited for such plans or persons.
    
 
   
DIVIDENDS, DISTRIBUTIONS, AND TAXES
    
 
   
DIVIDENDS.
    
 
   
GOVERNMENT BOND AND TAX FREE FUNDS. The Government Bond and Tax Free Funds will
declare and pay dividends from net investment income monthly and net realized
short-term or long-term capital gains, if any, annually. In order to be entitled
to a dividend, an investor must have acquired shares of a fund prior to the
close of business on the record date. A shareholder should be cautioned,
however, before purchasing shares of a fund immediately prior to a distribution.
Dividends and distributions paid by the funds have the effect of reducing net
asset value per share on the record date by the amount of the payment.
Therefore, a dividend or distribution of record shortly after the purchase of
shares by an investor represents, in substance, a return of capital.
    
 
   
PRIMARY AND MONEY MARKET FUNDS. At 3:00 p.m. Central Time, on each day that the
Exchange is open for trading other than SM&R's business holidays described
above, the Primary and Money Market Funds each will declare a dividend of all of
its net investment income to shareholders of record on that date. Such dividends
will be paid monthly.
    
 
   
DIVIDEND REINVESTMENTS. Dividends and capital gains will be automatically
reinvested at net asset value in additional shares of the fund making such
distribution unless SM&R is instructed otherwise in writing. Distributions not
reinvested are paid by check or transmitted to your bank account through an ACH
transaction, if elected. If the Postal Service cannot deliver your check, or if
your check remains uncashed for six months, the funds reserve the right to
reinvest your
    
 
                                       47
<PAGE>
   
distribution check in your account at the net asset value on the business day of
the reinvestment and to reinvest all future distributions in shares of the
applicable fund(s). Dividends and capital gains declared in December to
shareholders of record in December and paid the following January will be
taxable to shareholders as if received in December. This is a convenient way to
accumulate additional shares and maintain or increase the shareholder's earning
base. Of course, any shares so acquired remain at market risk.
    
 
   
Shareholders have the right to change their election with respect to the receipt
of distributions by notifying SM&R in writing, but any such change will be
effective only as to distributions for which the record date is seven or more
business days after SM&R has received the shareholder's written request.
    
 
   
TAXABILITY OF DIVIDENDS. Dividends you receive from the Government Bond,
Primary, and Money Market Funds, whether reinvested or taken as cash, are
generally considered taxable. A fund's long-term capital gains distributions are
taxable as capital gains; dividends from other sources are generally taxable as
ordinary income. Some dividends paid in January may be taxable as if they had
been paid the previous December. The Form 1099 that is mailed to you every
January details your dividends and their federal tax category, although you
should verify your tax liability with your tax professional.
    
 
   
The Tax Free Fund intends to distribute tax-exempt dividends that shareholders
may exclude from their gross income for federal income tax purposes. However,
the Tax Free Fund may invest a portion of its assets in securities that generate
income that is not exempt from federal or state income tax. Income exempt from
federal tax may be subject to state and local income tax. Any capital gains
distributed by the Tax Free Fund may be taxable. Also, you should also keep in
mind that certain income from the Tax Free Fund may be subject to the federal
alternative minimum tax.
    
 
   
BACKUP WITHHOLDING. Backup withholding of federal income tax may be applied at
the rate of 31% from taxable dividends, distributions, and redemption proceeds
(including exchanges) if you fail to furnish the Company with a correct and
properly certified Social Security or Employer Identification Number when you
sign your application, or if you underreport your income to the Internal Revenue
Service.
    
 
   
TAXABILITY OF TRANSACTIONS. Any time you sell or exchange shares, it is
considered a taxable event for you. Depending on the purchase price
    
 
                                       48
<PAGE>
   
and the sale price of the shares you sell or exchange, you may have a gain or a
loss on the transaction. You are responsible for any tax liabilities generated
by your transactions. You should consult with a tax advisor concerning the tax
reporting requirements in effect on the redemption or exchange of such shares.
    
 
   
REDEEMING SHARES
    
 
   
You can redeem fund shares at net asset value, plus any applicable CDSC,
determined on the date the request is received by SM&R in proper form. A
redemption request must be addressed to Securities Management and Research,
Inc., 2450 South Shore Boulevard, Suite 400, League City, Texas 77573.
    
 
   
If uncertain of the redemption requirements, investors should call Investor
Services or write SM&R. Payment will be made as soon as practicable and normally
within seven days after receipt of a redemption request in proper form. We
currently charge a fee in the amount of $8.00 for redemptions by wire under
$5,000.
    
 
   
If the shares being redeemed were purchased by wire, certified check, money
order, or other immediately available funds, redemption proceeds will be mailed
no later than the seventh calendar day following receipt. For shares purchased
by a personal check or ACH transfer, SM&R will process your redemption but will
generally delay sending you the proceeds for up to ten (10) business days to
allow the check or transfer to clear.
    
 
   
TELEPHONE REDEMPTIONS. You may request redemptions by telephone if you have
completed the account application and requested this option. This redemption
feature can only be used if:
    
 
   
(a) the redemption proceeds are to be mailed to the address of record or wired
    to the pre-authorized bank account indicated on the account application;
    
 
   
(b) there has been no change of address of record or pre-authorized bank account
    within the preceding 30 business days;
    
 
   
(c) the shares to be redeemed are not in certificate form;
    
 
   
(d) the security procedures discussed under "Special Purchase Plans And
    Services--Exchange Privilege" have been met; and
    
 
   
(e) the proceeds of the redemption do not exceed $25,000.
    
 
                                       49

SYSTEMATIC WITHDRAWAL PLAN. The Company has a Systematic Withdrawal Plan
("Withdrawal Account"), which permits shareholders having an account value of
$5,000 or more to automatically withdraw a minimum of $50 monthly or each
calendar quarter on or about the 20th of the applicable month. Shareholders
maintaining a Withdrawal Account may elect to have the withdrawal proceeds
automatically deposited in their pre-authorized bank account via an ACH
transaction. This is accomplished by completing the relevant section of the
account application and returning it to SM&R. See "Special Purchase Plans and
Services--Electronic Transfers" for additional information. It may not be
advisable for shareholders to maintain a Withdrawal Account while concurrently
purchasing shares of the Government Bond Fund or the Tax Free Fund because of
the sales charge or CDSC (as applicable) involved in additional purchases. You
should carefully consider such purchases and contact your financial adviser
regarding their advisability. Dividends and capital gains distributions will
automatically be reinvested in additional shares at net asset value. As with
other redemptions, a withdrawal is a sale for federal income tax purposes. The
Systematic Withdrawal Plan will automatically terminate if all shares are
liquidated or withdrawn from the account. Certificates are not issued for shares
held in a Withdrawal Account and certificates held, if any, must be surrendered
when shares are transferred to a Withdrawal Account. No account covered by a
Letter of Intent can be changed to a Systematic Withdrawal Plan until such time
as the Letter of Intent is fulfilled or terminated, nor can an account under a
Systematic Withdrawal Plan be placed under a Letter of Intent.
    
 
   
REINVESTMENT PRIVILEGE. Within ninety (90) days of a redemption of Class A
shares of a fund, a shareholder may reinvest all or part of the proceeds in
Class A shares of that same fund at the net asset value next computed after
receipt of the proceeds to be reinvested by SM&R. The shareholder must ask the
transfer agent for this privilege at the time of reinvestment. Prior to
reinvestment of redemption proceeds, a shareholder is encouraged to consult with
his or her accountant or tax advisor to determine any possible tax ramifications
of such a transaction. Each fund managed by SM&R may amend, suspend, or cease
offering this privilege at any time as to shares redeemed after the date of the
amendment, suspension, or cessation.

<PAGE>
   
For further information about the "Systematic Withdrawal Plan" and "Reinvestment
Privilege," contact a registered representative or SM&R.
    
 
   
"PROPER FORM" means the request for redemption must include:
    
 
   
(1) your share certificates, if issued;
    
 
   
(2) your letter of instruction or a stock assignment specifying the fund,
    account number, and number of shares or dollar amount to be redeemed. Both
    share certificates and stock powers, if any, must be endorsed and executed
    exactly as the fund shares are registered. It is suggested that certificates
    be returned by certified mail for your protection;
    
 
   
(3) any required signature guarantees (see "Signature Guarantees" below); and
    
 
   
(4) other supporting legal documents, if required in the case of estates,
    trusts, guardianships, divorce, custodianships, corporations, partnerships,
    pension or profit sharing plans, retirement plans, and other organizations.
    
 
   
Please keep in mind that as a shareholder, it is your responsibility to ensure
that all requests are submitted to the Company's transfer agent in proper form
for processing.
    
 
   
SIGNATURE GUARANTEES. A signature guarantee verifies the authenticity of your
signature. Signature guarantees are required when:
    
 
   
(1) the proceeds of the redemption exceed $25,000;
    
 
   
(2) the proceeds (in any amount) are to be paid to someone OTHER THAN the
    registered owner(s) of the account;
    
 
   
(3) the proceeds (in any amount) are to be sent to any address OTHER THAN the
    shareholder's address of record, pre-authorized bank account or exchanged to
    one of the other funds managed by SM&R; or
    
 
   
(4) the Company or its transfer agent believes a signature guarantee would
    protect against potential claims based on the transfer instructions,
    including, when the authority of a representative of a corporation,
    partnership, association, or other entity has not been established to the
    satisfaction of the Company or transfer agent.
    
 
                                       51
<PAGE>
   
You should be able to obtain an acceptable signature guarantee from a bank,
broker, dealer, municipal securities dealer or broker, government securities
dealer or broker, credit union, national securities exchange, or registered
securities association. WITNESSING OR NOTARIZATION IS NOT SUFFICIENT.
    
 
   
TEXAS OPTIONAL RETIREMENT PROGRAM. You may not redeem shares of the Government
Bond Fund, Primary Fund, and Money Market Fund in any account established under
the Texas Optional Retirement Program, unless SM&R receives satisfactory
evidence from the state that one of the following conditions exist:
    
 
   
(1) death of the employee;
    
 
   
(2) termination of service with the employer; or
    
 
   
(3) retirement of employee.
    
 
   
CHECK WRITING OPTION. Check writing is available in the Money Market Fund to
investors having an account value of $1,000 or more. $250 is the minimum check
amount under the check writing option. This option is not available on IRAs or
TSAs. Shareholders wishing to avail themselves of this option must complete the
check writing option signature card in the Prospectus. After obtaining specimen
signatures and the fully executed card, SM&R will order checks and arrange for
the shareholder's checks to be honored by a bank. Investments made by personal
check or third party check will be held for fifteen (15) business days following
the investment during which time checks may not be drawn on the amount of such
investment. This service may be terminated or suspended or additional charges
may be imposed for this service. Shareholders will be provided the initial
checkbook free of charge. There will be a $5 fee for re-orders. Shareholders
will be allowed to write ten (10) checks free each calendar quarter.
    
 
   
When a check is presented for payment, SM&R, as the shareholder's agent, will
cause each fund to redeem a sufficient number of full and fractional shares to
cover the amount of the check. Shareholders will continue to be entitled to
dividends on their shares up to the time the check is presented to SM&R for
payment. If the amount of the check is greater than the value of the shares held
in the shareholder's account for more than fifteen (15) business days at the
time the check is presented for payment, the check will be returned to the payee
as not being covered by sufficient funds, and the shareholder will be subject to
extra charges as a result.

<PAGE>
   
Primary Fund shareholders that had check writing privileges prior to December
31, 1998 will be permitted to continue writing checks on the Primary Fund
subject to the terms applicable to the Money Market Fund described above.
SHAREHOLDERS USING THE PRIMARY FUND CHECK WRITING OPTION SHOULD BE AWARE THAT
WRITING A CHECK IS A REDEMPTION OF SHARES. THOSE SHARES MAY BE WORTH LESS WHEN
THE CHECK IS PRESENTED FOR PAYMENT THAN WHEN THE CHECK WAS WRITTEN.
    
 
   
REDEMPTION OF SMALL ACCOUNTS. The Company reserves the right to redeem shares in
any account (which will be promptly paid to the shareholder) if, due to your
redemptions, the value of the account falls below $100 in the case of the
Government Bond and Tax Free Funds or $1,000 in the case of the Primary and
Money Market Funds. You will be notified that the value of your account is less
than the required minimum indicated above and allowed at least 60 days to make
an additional investment to increase the value of your account above the
required minimum. The Board of Directors may, from time to time, change such
required minimum investment.
    
 
   
RIGHTS RESERVED BY THE COMPANY. The Company, acting through its transfer agent,
reserves the right:
    
 
   
  - to waive or lower investment minimums;
    
 
   
  - to accept initial purchases by telephone from a registered representative;
    
 
   
  - to refuse any purchase order;
    
 
   
  - to cancel or rescind any purchase or exchange at any time prior to receipt
    by the shareholder of written confirmation or, if later, within five (5)
    business days of the transaction;
    
 
   
  - to freeze an account and suspend account services when notice has been
    received of a dispute involving the account owners or other parties or there
    is reason to believe a fraudulent transaction may occur;
    
 
   
  - to restrict or refuse the use of faxed redemptions where there is a question
    as to the validity of the request or proper documents have not been
    received;
    
 
   
  - to otherwise modify the conditions of purchase and any services at any time;
    or
    
 
   
  - to act on instructions not believed to be genuine.

THE FUNDS AND MANAGEMENT
    
- -------------------------------------------------------------------
 
   
INVESTMENT ADVISOR
    
 
   
The Company's Board of Directors has delegated to Securities Management and
Research, Inc. ("SM&R"), the funds' investment adviser, the management of the
funds' day-to-day business and affairs. In addition, SM&R invests the funds'
assets, provides administrative services, and serves as transfer agent,
custodian, dividend paying agent, and underwriter.
    
 
   
SM&R is a wholly-owned subsidiary of American National Insurance Company
("American National"). SM&R was incorporated in 1964 and has managed mutual
funds since 1966. SM&R does and may, from time to time, serve as investment
adviser to other clients including employee benefit plans, other investment
companies, banks, foundations and endowment funds.
    
 
   
Under the Advisory Agreements with the Company, SM&R is paid an investment
advisory fee, which is calculated separately for each fund, as compensation for
its services. The agreement provides that SM&R will receive advisory fees as set
forth below.
    
 
   
GOVERNMENT BOND FUND AND TAX FREE FUND. We deduct an investment advisory fee
from the value of the shares each day. We calculate this fee for the Government
Bond and Tax Free Funds at the annual rate as follows:

</TABLE>
    
 
   
MONEY MARKET FUND AND PRIMARY FUND. For the Money Market and Primary Funds, we
calculate the investment advisory fee at the annual rate of 0.50% of each fund's
average daily net asset value.
    
 
   
After applicable fee waivers, SM&R received total advisory fees from the
Government Bond Fund, Tax Free Fund, and Primary Fund for the fiscal year ended
August 31, 1998 which represented [____]%, [____]%, and [___]%, respectively, of
each such fund's average daily
    
 
                                       54

net assets. The Money Market Fund was not in operation during the fiscal year
ended August 31, 1998.
    
 
   
ADMINISTRATIVE SERVICES
    
 
   
Under its Administrative Service Agreement with the Company, SM&R also receives
an administrative service fee from each fund at the annual rate of average daily
net asset values as follows:

</TABLE>
    
 
   
REIMBURSEMENTS AND WAIVERS
    
 
   
SM&R has agreed to pay (or to reimburse each fund for) each fund's regular
operating expenses in excess of 1.25% (0.35% for the Money Market Fund) per year
of such fund's average daily net assets. Regular operating expenses include the
advisory fee and administrative service fee, if any, paid to SM&R, but do not
include 12b-1 fees, class-specific expenses, interest, taxes, commissions, and
other expenses incidental to portfolio transactions. SM&R received
administrative service fees of [___]% for the Government Bond Fund; [___]% for
the Primary Fund; and [___]% for the Tax Free Fund for the fiscal year ended
August 31, 1998 of each fund's average daily net assets. The Money Market Fund
was not in operation during the fiscal year ended August 31, 1998.
    
 
   
In order to improve the yield and total return of any fund of the Company, SM&R
may from time to time voluntarily waive or reduce all or any portion of its
advisory fee, administrative fee, and/or assume certain or all expenses of any
fund of the Company while retaining its ability to be reimbursed for such fees
prior to the end of the fiscal year. Fee waivers and/or reductions, other than
those stated in the Administrative Service Agreement, may be rescinded by SM&R
at any time without notice to investors. SM&R has agreed to continue to waive
the advisory fee for the Tax Free Fund and reimburse expenses incurred by the
Government Bond and Primary Funds to the extent that regular operating expenses
exceed average daily net assets as follows: 0.80% for the Primary Fund and 1.00%
for the Government Bond Fund.

FINANCIAL HIGHLIGHTS                                        GOVERNMENT BOND FUND
    
- -------------------------------------------------------------------
 
   
The following financial highlights table is intended to help you understand the
Government Bond Fund's financial performance for the past five years. Certain
information reflects financial results for a single share outstanding throughout
each period shown. The total returns in the table represent the rate that an
investor would have earned (or lost) on an investment in the Government Bond
Fund (assuming reinvestment of all dividends and distributions) prior to
addition of multiple classes of shares, but do not reflect any sales loads that
would be imposed on the purchase or sale of any shares. This information is
derived from the financial statements of the Government Bond Fund which for the
years ended through August 31, 1997 have been audited by KPMG Peat Marwick LLP
and for the year ended August 31, 1998 has been audited by Tait, Weller & Baker,
CPA. Each independent auditor's report, along with the Government Bond Fund's
financial statements, are incorporated by reference into the Statement of
Additional Information, which is available upon request. IF MULTIPLE CLASSES OF
SHARES OF THE GOVERNMENT BOND FUND HAD BEEN IN EXISTENCE DURING THE PAST FIVE
YEARS, THE FINANCIAL PERFORMANCE OF CLASS A, B, AND C SHARES OF THE GOVERNMENT
BOND FUND WOULD HAVE BEEN LOWER THAN DEPICTED BECAUSE OF THE IMPOSITION OF
DISTRIBUTION AND/OR SERVICE (12b-1) FEES.

- -------------------------------------------------------------------
 
   
The following financial highlights table is intended to help you understand the
Tax Free Fund's financial performance since inception. Certain information
reflects financial results for a single share outstanding throughout each period
shown. The total returns in the table represent the rate that an investor would
have earned (or lost) on an investment in the Tax Free Fund (assuming
reinvestment of all dividends and distributions) prior to addition of multiple
classes of shares, but do not reflect any sales loads that would be imposed on
the purchase or sale of any shares. This information is derived from the
financial statements of the Tax Free Fund which for the years ended through
August 31, 1997 have been audited by KPMG Peat Marwick LLP and for the year
ended August 31, 1998 has been audited by Tait, Weller & Baker, CPA. Each
independent auditor's report, along with the Tax Free Fund's financial
statements, are incorporated by reference into the Statement of Additional
Information, which is available upon request. IF MULTIPLE CLASSES OF SHARES OF
THE TAX FREE FUND HAD BEEN IN EXISTENCE DURING THE PAST FIVE YEARS, THE
FINANCIAL PERFORMANCE OF CLASS A, B, AND C SHARES OF THE TAX FREE FUND WOULD
HAVE BEEN LOWER THAN DEPICTED BECAUSE OF THE IMPOSITION OF DISTRIBUTION AND/OR
SERVICE (12b-1) FEES.

APPENDIX
    
 
   
(Description of Ratings Used in Prospectus)
    
- -------------------------------------------------------------------
 
   
BOND RATINGS
    
 
   
DESCRIPTION OF STANDARD & POOR'S CORPORATION'S BOND RATING:
    
 
   
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 obligations 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 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, which
       could lead to the obligor's inadequate capacity to meet its financial
       commitment on the obligation.
    
 
   
B     An obligation rated "B" is more vulnerable to nonpayment than obligations
       rated "BB," but the obligor currently has the capacity to meet its
       financial commitment on the obligation.
    
 
                                      A-1
<PAGE>
   
       Adverse business, financial, or economic conditions will likely impair
       the obligor's capacity or willingness to meet its financial commitment on
       the obligation.
    
 
   
DESCRIPTION OF MOODY'S INVESTOR'S SERVICE, INC.'S BOND RATINGS:
    
 
   
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-edge." 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,
       fluctuation of protective elements may be of greater amplitude, or there
       may be other elements present which make the long-term risks appear
       somewhat greater than in Aaa securities.
    
 
   
A     Bonds which are rated "A" possess many favorable investment attributes and
       are to be considered as upper medium grade obligations. Factors giving
       security to principal and interest are considered adequate but elements
       may be present which suggest a susceptibility to impairment sometime in
       the future.
    
 
   
Baa   Bonds which are rated "Baa" are considered as medium grade obligations,
       I.E., they are neither highly protected nor poorly secured. Interest
       payments and principal security appear adequate for the present, but
       certain protective elements may be lacking or may be characteristically
       unreliable over any great length of time. Such bonds lack outstanding
       investment characteristics and in fact have speculative characteristics
       as well.
    
 
   
Ba    Bonds which are rated "Ba" are judged to have speculative elements; their
       future cannot be considered as well assured. Often the protection of
       interest and principal payments may be very moderate and thereby not well
       safeguarded during both good and bad times over the future. Uncertainty
       of position characterizes bonds in this class.
    
 
                                      A-2
<PAGE>
   
B     Bonds which are rated "B" generally lack characteristics of the desirable
       investment. Assurance of interest and principal payments or of
       maintenance of other terms of the contract over any long period of time
       may be small.
    
 
   
DESCRIPTION OF FITCH INVESTORS SERVICE BOND RATINGS:
    
 
   
AAA  Obligations which have the highest rating assigned by Fitch IBCA on its
       national rating scale for that country. This rating is automatically
       assigned to all obligations issued or guaranteed by the sovereign state.
       Capacity for timely repayment of principal and interest is extremely
       strong, relative to other obligors in the same country.
    
 
   
AA   Obligations for which capacity for timely repayment of principal and
       interest is very strong relative to other obligors in the same country.
       The risk attached to these obligations differs only slightly from the
       country's highest rated debt.
    
 
   
A     Obligations for which capacity for timely repayment of principal and
       interest is strong relative to other obligors in the same country.
       However, adverse changes in business, economic or financial conditions
       are more likely to affect the capacity for timely repayment than for
       obligations in higher rated categories.
    
 
   
BBB  Obligations for which capacity for timely repayment of principal and
       interest is adequate relative to other obligors in the same country.
       However, adverse changes in business, economic or financial conditions
       are more likely to affect the capacity for timely repayment than for
       obligations in higher rated categories.
    
 
   
MUNICIPAL NOTE RATINGS
    
 
   
DESCRIPTION OF MOODY'S INVESTOR SERVICE INC.'S MUNICIPAL NOTE RATINGS:
    
 
   
MIG 1/VMIG 1 This designation denotes best quality. There is present strong
                protection by established cash flows, superior liquidity support
                or demonstrated broad-based access to the market refinancing.
    
 
                                      A-3
<PAGE>
   
MIG 2/VMIG 2 This designation denotes high quality. Margins of protection are
                ample although not so large as in the preceding group.
    
 
   
MIG 3/VMIG 3 This designation denotes favorable quality. All security elements
                are accounted for but there is lacking the undeniable strength
                of the preceding grades. Liquidity and cash flow protection may
                be narrow and market access for refinancing is likely to be less
                well established.
    
 
   
MIG 4/VMIG 4 This designation denotes adequate quality. Protection commonly
                regarded as required of an investment security is present and
                although not distinctly or predominantly speculative, there is
                specific risk.
    
 
   
DESCRIPTION OF STANDARD AND POOR'S MUNICIPAL NOTE RATINGS:
    
 
   
Until June 29, 1984, S&P used the same rating symbols for notes and bonds. After
June 29, 1984, for new municipal note issues due in three years or less the
ratings below usually will be assigned. Notes maturing beyond three years will
most likely receive a bond rating of the type recited above.
    
 
   
SP-1  Strong capacity to pay principal and interest. An issue determined to
       possess a very strong capacity to pay debt service is 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.
    
 
   
COMMERCIAL PAPER RATINGS
    
 
   
DESCRIPTION OF STANDARD & POOR'S CORPORATION'S THREE HIGHEST COMMERCIAL PAPER
RATINGS:
    
 
   
Commercial paper rated "A" by Standard & Poor's Corporation has the following
characteristics: Liquidity ratios are adequate to meet cash requirements.
Long-term senior debt is generally rated "A" or better. The issuer has access to
at least two additional channels of borrowing. Basic earnings and cash flow have
an upward trend with allowance made for unusual circumstances. Typically, the
issuer's industry is well established and the issuer has a strong position
within
    
 
                                      A-4
<PAGE>
   
the industry. The reliability and quality of management are unquestioned.
Relative strength or weakness of the above factors determine whether the
issuer's commercial paper is rated as follows:
    
 
   
A-1   This designation indicates that the degree of safety regarding timely
       payment is strong. Those issues determined to possess extremely strong
       safety characteristics are denoted with a plus sign (+) designation.
    
 
   
A-2   Capacity for timely payment on issues with this designation is
       satisfactory. However, the relative degree of safety is not as high as
       for issues designated "A-1".
    
 
   
DESCRIPTION OF MOODY'S INVESTORS SERVICE, INC.'S THREE HIGHEST COMMERCIAL PAPER
RATINGS:
    
 
   
Among the factors considered by Moody's Investors Service, Inc. is assigning
commercial paper ratings are the following: (1) evaluation of the management of
the issuer; (2) economic evaluation of the issuer's industry or industries and
an appraisal of the risks which may be inherent in certain areas; (3) evaluation
of the issuer's products in relation to competition and customer acceptance; (4)
liquidity; (5) amount and quality of long-term debt; (6) trend of earnings over
a period of ten years; (7) financial strength of a parent company and the
relationships which exist with the issuer; and (8) recognition of the management
of obligations which may be present or may arise as a result of public interest
questions and proportions to meet such obligations. Relative differences in
strength and weakness in respect to these criteria would establish a rating in
one of three classifications; "P-1," "P-2" or "P-3."
    
 
   
DESCRIPTION OF FITCH INVESTORS SERVICE COMMERCIAL PAPER, MEDIUM-TERM NOTES, AND
MUNICIPAL AND INVESTMENT NOTES.
    
 
   
F-1+  Exceptionally Strong Credit Quality. Issues assigned this rating are
       regarded as having the strongest degree of assurance for timely payment.
    
 
   
F-1   Very Strong Credit Quality. Issues assigned this rating reflect an
       assurance of timely payment only slightly less in degree than issues
       rated "F-1+."
    
 
   
F-2   Good Credit Quality. Issues assigned this rating have a satisfactory
       degree of assurance for timely payment, but the margin of safety is not
       as great as for issues assigned "F-1+" and "F-1" ratings.
    
 
                                      A-5
<PAGE>
   
F-3   Fair Credit Quality. Issues assigned this rating have characteristics
       suggesting that the degree of assurance for timely payment is adequate,
       however, near-term adverse changes could cause these securities to be
       rated below investment grade.
    
 
   
F-5   Weak Credit Quality. Issues assigned this rating have characteristics
       suggesting a minimal degree of assurance for timely payment and are
       vulnerable to near-term adverse changes in financial and economic
       conditions.
    
 
   
DESCRIPTION OF DUFF & PHELP'S TWO HIGHEST COMMERCIAL RATINGS:
    
 
   
Duff & Phelp's commercial paper ratings place emphasis on liquidity, considering
not only cash from operations, but access to alternative sources of funds,
including trade credit, bank lines and capital markets. Relative differences in
strength and weakness is rated by Duff & Phelp's as Duff-1 or Duff-2; Duff-1
being the highest commercial paper rating and Duff-2 being the second highest
rating.
    
 
   
DESCRIPTION OF THOMSON BANKWATCH, INC.'S TWO HIGHEST COMMERCIAL RATINGS:
    
 
   
Thomson Bankwatch, Inc.'s ratings of United States commercial banks, thrifts,
and non-bank banks, non-United States banks, and broker-dealers are based upon
among other things, five years's financial information and the issuer's most
recent regulatory filings. Relative differences in strength and weakness are
rated by Thomson Bankwatch, Inc.
    
 
   
TBW-1 The highest category; indicates a very high likelihood that principal and
       interest will be paid on a timely basis.
    
 
   
TBW-2 The second-highest category; while the degree of safety regarding timely
       repayment of principal and interest is strong, the relative degree of
       safety is not as high as for issues rated TBW-1.

RISK/RETURN SUMMARY                                    SM&R GOVERNMENT BOND FUND
    
- -------------------------------------------------------------------
 
   
GOVERNMENT BOND FUND'S INVESTMENT OBJECTIVE
                   To provide as high a level of current income,
                   liquidity, and safety of principal as is consistent with
                   prudent investment risks through investment in a portfolio
                   consisting primarily of securities issued or guaranteed by
                   the U.S. Government, its agencies, or instrumentalities.
    
 
   
GOVERNMENT BOND FUND'S PRINCIPAL INVESTMENT STRATEGIES
                   The Government Bond Fund normally invests at
                   least 65% of its assets in securities issued or guaranteed by
                   the U.S. Government, its agencies, or instrumentalities.
                   These may include Treasuries and mortgage-backed securities,
                   such as Ginnie Maes, Freddie Macs, and Fannie Maes. This fund
                   may also invest assets in collateralized mortgage
                   obligations.
    
 
   
                   The Government Bond Fund may invest in zero coupon bonds,
                   which are U.S. Government obligations. The fund may also
                   invest in commercial paper, certificates of deposit,
                   corporate debt securities rated "A" or higher, and repurchase
                   agreements.
    
 
   
PRINCIPAL RISKS OF INVESTING IN THE GOVERNMENT BOND FUND
                   You could lose money on your investment in the
                   Government Bond Fund, or it could underperform other
                   investments, if any of the following occurs:
    
   
                   - interest rates rise (thus causing a decline in the market
                     value of debt securities)
    
   
                   - the worldwide demand for U.S. government securities falls
    
   
                   - interest rates fall enough to prompt an unexpected number
                     of people to refinance (or prepay) their mortgages
    
   
                   - interest rates rise enough to cause fewer people than
                     expected to repay their mortgages early
    
   
                   - if any bonds the fund owns are downgraded in credit rating
                     or go into default

WHO MAY WANT TO INVEST IN THE GOVERNMENT BOND FUND
                   The Government Bond Fund may be
                   appropriate if you:
    
   
                   - are seeking a regular stream of income to meet current
                     needs
    
   
                   - are seeking higher potential returns than money market
                     funds and are willing to accept moderate risk of volatility
    
   
                   - are retired or nearing retirement
    
 
   
                   The Government Bond Fund may NOT be appropriate if you:
    
   
                   - are investing for maximum return over a long time horizon

RISK/RETURN SUMMARY                                           SM&R TAX FREE FUND
    
- -------------------------------------------------------------------
 
   
TAX FREE FUND'S INVESTMENT OBJECTIVE
                   To provide as high a level of interest income
                   largely exempt from federal income taxes as is consistent
                   with preservation of capital through investment of at least
                   80% of its net assets in tax-exempt securities during normal
                   market conditions.
    
 
   
TAX FREE FUND'S PRINCIPAL INVESTMENT STRATEGIES
                   The Tax Free Fund invests primarily in tax-
                   exempt securities. During normal market conditions, this fund
                   invests at least 80% of its assets in municipal securities
                   that pay interest exempt from federal income taxes. This fund
                   may not invest more than 20% of its assets in UNRATED
                   municipal securities. These securities may be less liquid
                   than comparably rated municipal securities and involve
                   somewhat greater risk. This fund may also invest up to 20% of
                   its assets in Government guaranteed taxable bonds, highly
                   rated corporate bonds, or commercial paper.
    
 
   
PRINCIPAL RISKS OF INVESTING IN THE TAX FREE FUND
                   You could lose money on your investment in the
                   Tax Free Fund, or it could underperform other investments, if
                   any of the following occurs:
    
   
                   - interest rates rise (thus causing a decline in the market
                     value of debt securities)
    
   
                   - if any bonds the fund owns are downgraded in credit rating
                     or go into default
    
   
                   - certain securities become harder to value or to sell at a
                     fair price
    
 
   
                   ALSO, SOME OF YOUR DIVIDEND INCOME MAY BE TAXABLE.

- -------------------------------------------------------------------
 
   
PRIMARY FUND'S INVESTMENT OBJECTIVE
                   To seek maximum current income consistent
                   with capital preservation and liquidity through investment
                   primarily in commercial paper.
    
 
   
PRIMARY FUND'S PRINCIPAL INVESTMENT STRATEGIES
                   The Primary Fund invests primarily in
                   commercial paper. Commercial paper is short-term unsecured
                   promissory notes issued by corporations. This fund will only
                   invest in commercial paper rated in one of the two highest
                   rating categories.
    
 
   
                   The Primary Fund may also invest in:
    
   
                   - U.S. Government obligations;
    
   
                   - corporate debt obligations maturing in five years or less
                     and rated "A" or higher;
    
   
                   - certificates of deposit; and
    
   
                   - repurchase agreements.
    
 
   
PRINCIPAL RISKS OF INVESTING IN THE PRIMARY FUND
                   You could lose money on your investment in the
                   Primary Fund, or it could underperform other investments, if
                   any of the following occurs:
    
   
                   - interest rates rise (thus causing a decline in the market
                     value of debt securities)
    
   
                   - if any of the fund's investments are downgraded in credit
                     rating or go into default
    
 
   
                   By limiting its investments as described above, the Primary
                   Fund may not achieve as high a level of current income as a
                   fund investing in lower-rated securities or longer-term
                   securities.

WHO MAY WANT TO INVEST IN THE PRIMARY FUND

                   - are seeking a regular stream of income to meet current
                     needs

                   - require absolute stability of your principal

MONEY MARKET FUND'S INVESTMENT OBJECTIVE
                   To seek the highest current income consistent
                   with the preservation of capital and maintenance of
                   liquidity.
    
 
   
MONEY MARKET FUND'S PRINCIPAL INVESTMENT STRATEGIES
                   The Money Market Fund seeks to achieve its
                   objective by investing in high-quality short-term money
                   market instruments, including: U.S. Government obligations,
                   certificates of deposit, banker's acceptances, commercial
                   paper, collateralized mortgage obligations, and corporate
                   bonds and notes. This fund limits its investments to those
                   short-term securities that it determines present minimal
                   credit risk and meet certain rating requirements (in the two
                   highest short-term rating categories).
    
 
   
PRINCIPAL RISKS OF INVESTING IN THE MONEY MARKET FUND
                   The Money Market Fund is subject to the
                   following risks:
    
   
                   - that interest rates may rise (thus causing a decline in the
                     market value of debt securities)
    
   
                   - that the fund's investments may be downgraded in credit
                     rating or go into default
    
 
   
                   However, the risks of investment in the Money Market Fund may
                   be expected to be less than for other mutual funds. By
                   limiting its investments as described above, this fund may
                   not achieve as high a level of current income as a fund
                   investing in lower-rated securities. Also, there is a remote
                   possibility that this fund's share value could fall below
                   $1.00, which could reduce the value of your account.

WHO MAY WANT TO INVEST IN THE MONEY MARKET FUND
                   The Money Market Fund may be appropriate if
                   you:
    
   
                   - require stability of principal
    
   
                   - are seeking a mutual fund for the cash portion of an asset
                     allocation program
    
   
                   - need to "park" your money temporarily
    
   
                   - consider yourself a saver rather than an investor
    
   
                   - are investing emergency reserves
    
 
   
                   The Money Market Fund may NOT be appropriate if you:
    
   
                   - want federal deposit insurance
    
   
                   - are seeking an investment that is likely to outpace
                     inflation
    
   
                   - are investing for retirement or other goals that are many
                     years in the future
    
   
                   - are investing for growth or maximum current income
    
   
AN INVESTMENT IN THE MONEY MARKET FUND IS NOT INSURED OR GUARANTEED BY THE
FEDERAL DEPOSIT INSURANCE CORPORATION OR ANY OTHER GOVERNMENT AGENCY. ALTHOUGH
THE MONEY MARKET FUND SEEKS TO PRESERVE THE VALUE OF YOUR INVESTMENT AT $1.00
PER SHARE, IT IS POSSIBLE TO LOSE MONEY BY INVESTING IN THE MONEY MARKET FUND.

RISK/RETURN SUMMARY
    
- -------------------------------------------------------------------
 
   
TYPES OF INVESTMENT RISK
    
 
   
As indicated above, each of the four funds may be subject to certain of the
following types of risks:
    
 
   
CREDIT RISK. The risk that the issuer of a security, or a party to a contract,
will default or otherwise not honor a financial obligation.
    
 
   
INTEREST RATE RISK. The risk of declines in market value of an income-bearing
investment due to changes in prevailing interest rates. With fixed-rate
securities, a rise in interest rates typically causes a decline in market
values, while a fall in interest rates typically causes an increase in market
values.
    
 
   
LIQUIDITY RISK. The risk that certain securities or other investments may be
difficult or impossible to sell at the time the fund would like to sell them or
at the price the fund values them. The fund may have to sell at a lower price,
sell other securities instead, or forego an investment opportunity, any of which
could have a negative effect on fund management or performance.
    
 
   
MANAGEMENT RISK. The risk that a strategy used by a fund's management may fail
to produce the intended result. This risk is common to all mutual funds.
    
 
   
MARKET RISK. The risk that the market value of a security may move up and down,
sometimes rapidly and unpredictably. The fluctuations may cause a security to be
worth less than the price originally paid for it, or less than it was worth at
an earlier time. Market risk may affect a single issuer, industry, sector of the
economy, or the market as a whole. This risk is common to all stocks and bonds
and the mutual funds that invest in them.
    
 
   
PREPAYMENT AND EXTENSION RISK. PREPAYMENT RISK is the risk that an unexpected
fall in prevailing interest rates will shorten the life of an outstanding
mortgage-backed security by increasing the actual or expected number of mortgage
prepayments, thereby reducing the security's value. EXTENSION RISK is the risk
that an unexpected rise in prevailing interest rates will extend the life of an
outstanding mortgage-backed security by reducing the actual or expected number
of mortgage prepayments, thereby reducing the security's value.

BAR CHART AND PERFORMANCE TABLE
    
 
   
The bar charts and performance tables shown below provide some indication of the
risks of investing in the funds and the variability of returns by showing each
fund's performance for each year since inception and by showing how each fund's
average annual returns for certain periods compare to those of a broad-based
securities market index. Because the Money Market Fund was not in operation
during these periods, it is not included in the bar chart or the performance
table.
    
 
   
The returns shown are based on an investment in the funds prior to the creation
of multiple classes of shares, but do not reflect any sales loads that would be
imposed on the purchase or sale of any shares.
    
 
   
Past performance is not necessarily an indication of how the funds will perform
in the future.

(1) "Other Expenses" include the 0.25% Administrative Service Fee. Because Class
    Y shares were not available prior to the date of this Prospectus, "Other
    Expenses" for Class Y shares are based on the expenses and average net
    assets of the Government Bond Fund and the Tax Free Fund for the fiscal year
    ended August 31, 1998. "Other Expenses" shown for the Money Market Fund are
    estimated for the current fiscal year ending August 31, 1999.

(2) The Fee Table does not reflect any fees waived or expenses assumed either
    contractually or voluntarily by the funds' manager, Securities Management
    and Research, Inc. ("SM&R"). Pursuant to the Administrative Service
    Agreement, SM&R will pay (or reimburse) each fund for regular operating
    expenses in excess of 1.25% (0.35% for the Money Market Fund) per year of
    such fund's average daily net assets. Regular operating expenses include the
    advisory fee and administrative fee, but do not include any 12b-1 fee or
    class-specific expenses.
    
 
   
    SM&R may also waive fees or assume expenses on a voluntary basis. During the
    fiscal year ended August 31, 1998, SM&R voluntarily waived fees of [___]%,
    [___]%, and [___]% for the Government Bond Fund, Primary Fund, and Tax Free
    Fund, respectively, and reimbursed expenses of [___]% for the Tax Free Fund.
    SM&R intends to continue to voluntarily waive the advisory fee for the Tax
    Free Fund. SM&R also intends to reimburse regular operating expenses that
    exceed average daily net assets as follows: 0.80% for the Primary Fund and
    1.00% for the Government Bond Fund. SM&R may discontinue or reduce any such
    waiver or reimbursement of expenses at any time without notice.
    
 
   
    The following table shows fees and expenses for the Government Bond,
    Primary, and Tax Free Funds for the year ended August 31, 1998 taking into

RISK/RETURN SUMMARY
    
- ------------------------------------------------
 
   
EXAMPLES OF EXPENSES
    
 
   
These examples are intended to help you compare the cost of investing in the
funds with the cost of investing in other mutual funds. These examples assume
that you invest $10,000 in each fund and applicable class thereof for the time
periods indicated, based on expenses before fee waivers and expense
reimbursements. These examples also assume that your investment has a 5% return
each year and that the funds' operating expenses remain the same. YOUR ACTUAL
COSTS MAY BE HIGHER OR LOWER THAN SHOWN.
    
 
   
You would pay the following expenses, based on these assumptions, if you
actually redeem all of your shares at the end of the period shown:

INVESTMENT OBJECTIVES AND POLICIES
    
- -------------------------------------------------------------------
 
   
Each fund pursues its own investment objective through various investment
policies and techniques. ONLY THE PRINCIPAL INVESTMENT STRATEGIES OF EACH FUND
AND THE PRINCIPAL TYPES OF SECURITIES EACH FUND PLANS TO PURCHASE ARE DESCRIBED
BELOW. These policies and techniques are not fundamental and may be changed by
the Board of Directors without shareholder approval.
    
 
   
Because of the market risks inherent in any investment, the funds may not
achieve their investment objectives. In addition, effective management of each
fund is subject to general economic conditions and to the ability and investment
techniques of management. The net asset value of each fund's shares will vary
and the redemption value of shares may be either higher or lower than the
shareholder's cost. Since each fund has a different investment objective, each
will have different investment results and incur different market, financial,
and other risks.
    
 
   
GOVERNMENT BOND FUND
(FORMERLY NAMED AMERICAN NATIONAL GOVERNMENT INCOME FUND SERIES)
    
 
   
The Government Bond Fund seeks to achieve its objective through investment of
65% or more of its total assets in securities issued or guaranteed by the U.S.
Government, its agencies or instrumentalities ("U.S. Government Obligations")
which include, but are not limited to, U.S. Treasury Bonds, Notes and Bills and
securities issued by instrumentalities of the U.S. Government.
    
 
   
U.S. GOVERNMENT OBLIGATIONS--There are two broad categories of U.S. Government
Obligations:
    
 
   
(1) direct obligations of the U.S. Treasury, and
    
 
   
(2) obligations issued or guaranteed by agencies or instrumentalities of the
    U.S. Government.
    
 
   
Some obligations issued or guaranteed by agencies or instrumentalities of the
U.S. Government are backed by the full faith and credit
    
 
                                       18
<PAGE>
   
of the United States (such as Government National Mortgage Association
Certificates); others, by the agency or instrumentality with limited rights of
the issuer to borrow from the U.S. Treasury (such as Federal National Mortgage
Association Bonds); and others, only by the credit of the issuer. No assurance
can be given that the U.S. Government would lend money to or otherwise provide
financial support to U.S. Government sponsored instrumentalities; it is not
obligated by law to do so.
    
 
   
MORTGAGE-BACKED SECURITIES--We anticipate that a substantial portion of the
Government Bond Fund's portfolio will consist of mortgage-backed securities
issued or guaranteed by the U.S. Government, its agencies, or instrumentalities.
These securities represent part ownership of pools of mortgage loans secured by
real property, such as certificates issued by the Government National Mortgage
Association ("GNMA" or "Ginnie Mae"), the Federal National Mortgage Association
("FNMA" or "Fannie Mae"), and the Federal Home Loan Mortgage Corporation
("FHLMC" or "Freddie Mac"). Mortgage-backed securities also include mortgage
pass-through certificates representing participation interests in pools of
mortgage loans originated by the U.S. Government and guaranteed by U.S.
Government agencies such as GNMA, FNMA, or FHLMC. Such certificates, which are
ownership interests in the underlying mortgage loans, differ from conventional
debt securities which provide for periodic payment of interest in fixed amounts
and principal payments at maturity or on specified dates. With pass-through
certificates, both principal and interest payments, including prepayments, are
passed through to the holder of the certificate and provide for monthly payments
of interest and principal. GNMA, a federal agency, issues pass-through
certificates that are guaranteed as to timely payment of principal and interest.
FNMA, a federally chartered and privately owned corporation, issues mortgage
pass-through securities and guarantees them as to timely payment of principal
and interest. FHLMC, a corporate instrumentality of the United States, issues
participation certificates that represent an interest in mortgages from FHLMC's
portfolio. FHLMC guarantees the timely payment of interest and the ultimate
collection of principal. FNMA and FHLMC are not backed by the full faith and
credit of the United States, although FNMA and FHLMC are authorized to borrow
from the U.S. Treasury to meet their obligations. Those mentioned are but a few
of the mortgage-backed securities currently available. The Government Bond Fund
    
 
                                       19
<PAGE>
   
will not purchase interest-only or principal-only mortgage-backed securities.
    
 
   
The yield characteristics of mortgage-backed securities differ from traditional
debt securities. Among the major differences are that interest and principal
payments are made more frequently, usually monthly, and that principal may be
prepaid at any time because the underlying mortgage loans generally may be
prepaid at any time. The average mortgage in a pool may be expected to be repaid
within about twelve (12) years. If mortgage interest rates decrease, the value
of the Government Bond Fund's securities will generally increase. However, we
anticipate that the average life of the mortgages in the pool will decrease as
borrowers refinance and prepay mortgages to take advantage of lower interest
rates. The Government Bond Fund invests the proceeds from such prepayments at
the then prevailing lower interest rates. On the other hand, if interest rates
increase, the value of the Fund's securities generally will decrease while it is
anticipated that borrowers will not refinance and, therefore, the average life
of the mortgages in the pool will be longer. In addition, if the Government Bond
Fund purchases such a security at a premium, a prepayment rate faster than
expected will reduce yield to maturity, while a prepayment rate slower than
expected will have the opposite effect of increasing yield to maturity.
Conversely, if the Government Bond Fund purchases these securities at a
discount, faster than expected prepayments will increase yield to maturity,
while slower than expected prepayments will reduce yield to maturity.
    
 
   
COLLATERALIZED MORTGAGE OBLIGATIONS--The Government Bond Fund may invest a
portion of its assets in collateralized mortgage obligations or "CMOs," which
are debt obligations collateralized by a portfolio or pool of mortgages,
mortgage-backed securities, or U.S. Government securities. Collateralized
obligations in which the Government Bond Fund may invest are issued or
guaranteed by a U.S. Government agency or instrumentality, such as the FHLMC. A
variety of types of collateralized obligations are currently available and
others may become available in the future. One should keep in mind that during
periods of rapid interest rate fluctuation, the price of a security, such as a
CMO, could either increase or decrease based on inherent interest rate risk.
Additionally, the risk of maturities shortening or lengthening in conjunction
with interest rate movement, could magnify the overall effect of the price
fluctuation.
    
 
                                       20
<PAGE>
   
A CMO is often issued in multiple classes with varying maturities and interest
rates. As a result the investor may obtain greater predictability of maturity
than with direct investments in mortgage-backed securities. Thus, classes with
shorter maturities may have lower volatility and lower yield while those with
longer maturities may have higher volatility and higher yields. This provides
the investor with greater control over the characteristics of the investment in
a changing interest rate environment. A more complete description of CMOs is
contained in the Statement of Additional Information.
    
 
   
The Government Bond Fund may also invest in parallel pay CMOs and Planned
Amortization Class CMOs ("PAC Bonds"). Parallel pay CMOs are structured to
provide payments of principal on each payment date to more than one class. PAC
Bonds generally require payments of a specified amount of principal on each
payment date. PAC Bonds are always parallel pay CMOs with the required principal
payment on such securities having the highest priority after interest has been
paid to all classes.
    
 
   
The Government Bond Fund may also invest in securities issued by private issuers
that represent an interest in or are secured by mortgage-backed securities
issued or guaranteed by the U.S. government or one of its agencies or
instrumentalities. In addition, the fund may invest in securities issued by
private issuers that represent an interest in or are secured by mortgage loans
or mortgage-backed securities without a government guarantee but usually have
some form of private credit enhancement.
    
 
   
ZERO COUPON BONDS--The Government Bond Fund may invest in zero coupon bonds,
which are debt obligations issued or purchased at a significant discount from
face value. The Government Bond Fund will only purchase zero coupon bonds which
are U.S. Government Obligations. The discount approximates the total amount of
interest the bonds will accrue and compound over the period until maturity or
the first interest payment date at a rate of interest reflecting the market rate
of the security at the time of issuance. Zero coupon bonds do not entitle the
holder to any periodic payments of interest prior to maturity. Its value as an
investment consists of the difference between its face value at the time of
maturity and the price for which it was acquired which is generally an amount
significantly less than face value (sometimes referred to as a "deep discount"
price). Zero coupon bonds require a higher rate of return to attract investors
who
    
 
                                       21
<PAGE>
   
are willing to defer receipt of cash. Accordingly, although not providing
current income, SM&R believes that zero coupon bonds can be effectively used to
lock in a higher rate of return in a declining interest environment. Such
investments may experience greater volatility in market value than debt
obligations which make regular payments of interest. The Fund will accrue income
on such investments for tax and accounting purposes, as required, which is
distributable to shareholders and which, because no cash is received at the time
of accrual, may require the liquidation of other portfolio securities to satisfy
the Fund's distribution obligations.
    
 
   
TAX FREE FUND (FORMERLY NAMED AMERICAN NATIONAL TAX FREE FUND SERIES)
    
 
   
The Tax Free Fund, as a matter of fundamental policy, seeks to achieve its
objective by investing at least 80% of the value of its net assets in municipal
securities the interest on which is exempt from federal income taxes.
    
 
   
The Tax Free Fund has no restrictions on the maturity of municipal securities in
which it may invest. Accordingly, it will seek to invest in municipal securities
of such maturities which, in the judgement of SM&R, the adviser, will provide a
high level of current income consistent with prudent investment, with
consideration given to market conditions.
    
 
   
The Tax Free Fund will invest, without percentage limitations, in municipal
securities having at the time of purchase one of the four highest municipal
ratings by Moody's Investor Service, Inc. ("Moody's"), Standard & Poor's
Corporation ("S&P"), or Fitch Investors Service (E.G., MIG 4 or higher by
Moody's) or in securities which are not rated, provided that, in the opinion of
SM&R, such securities are comparable in quality to those within the four highest
ratings. The rating agencies consider that bonds rated in the fourth highest
category may have some speculative characteristics and that changes in economic
conditions or other circumstances are more likely to lead to a weakened capacity
to make principal and interest payments on those bonds than is the case with
higher grade bonds. SM&R will only purchase bonds rated in such fourth category
if it believes that the purchase of such bonds is consistent with the Tax Free
Fund's investment objective. In the event the rating of an issue held by the Tax
Free Fund is changed by the rating service, such change will be considered by
the Tax Free Fund in its evaluation of
    
 
                                       22
<PAGE>
   
the overall investment merits of that security but such change will not
necessarily result in an automatic sale of the security. Any security held which
is subsequently downgraded below BBB by S&P or Baa by Moody's will be sold as
soon as it is advantageous to do so after the downgrade. A description of the
ratings may be found in the Appendix to this Prospectus.
    
 
   
Purchasing unrated municipal securities, which may be less liquid than
comparably rated municipal securities, involves somewhat greater risk and
consequently the Tax Free Fund may not invest more than 20% of its net assets in
unrated municipal securities. To attempt to minimize the risk of such
investments, SM&R will, prior to acquiring unrated securities, consider the
terms of the offering and various other factors to determine the issuer's
comparative credit rating and whether the securities are consistent with the Tax
Free Fund's investment objective and policies.
    
 
   
During normal market conditions, the Tax Free Fund will have at least 80% of its
net assets invested in municipal securities the income of which is fully exempt
from federal income taxation. Furthermore, under normal market conditions up to
20% of the Tax Free Fund's net assets, and as a temporary defensive measure
during abnormal market conditions, up to 50% of its net assets may be invested
in the following types of taxable fixed income obligations:
    
 
   
(1) obligations issued or guaranteed by the U.S. government, its agencies,
    instrumentalities or authorities (See "Government Bond Fund" above for an
    explanation of U.S. government obligations);
    
 
   
(2) corporate debt securities which at the date of the investment are rated A or
    higher by Moody's or by S&P;
    
 
   
(3) commercial paper which at the date of the investment is rated in one of the
    two top categories by Moody's or by S&P or if not rated, is issued by a
    company which at the date of the investment has an outstanding debt issue
    rated A or higher by Moody's or A or higher by S&P;
    
 
   
(4) certificates of deposit issued by U.S. banks which at the date of the
    investment have capital surplus and undivided profits of $1 billion as of
    the date of their most recently published financial statements; and
    
 
                                       23
<PAGE>
   
(5) repurchase agreements secured by U.S. government securities, provided that
    no more than 15% of the Fund's net assets will be invested in illiquid
    securities including repurchase agreements with maturities in excess of
    seven days.
    
 
   
To the extent income dividends include income from taxable sources, a portion of
a shareholder's dividend income may be taxable. (See "Dividends, Distributions,
and Taxes"). In addition, Congress could enact tax legislation such as a flat
tax rate that would make tax-free bonds less desirable to investors seeking ways
to reduce taxable income. If that were to occur, it could cause the value of the
securities to drop.
    
 
   
The Tax Free Fund's ability to achieve its objective depends partially on the
prompt payment by issuers of the interest on and principal of the municipal
securities held. A moratorium, default, or other non-payment of interest or
principal when due could, in addition to affecting the market value and
liquidity of the particular security, affect the market value and liquidity of
other municipal securities. Additionally, the market for municipal securities is
often thin and can be temporarily affected by large purchases and sales. As a
result, the Tax Free Fund will attempt to minimize risk by diversifying its
investments by investing no more than 5% of its net assets in the securities of
any one issuer (this limitation does not apply to investments issued or
guaranteed by the U.S. Government or its instrumentalities) and by investing no
more than 25% of its net assets in municipal securities issued in any one state
or territory. Each political subdivision, agency, instrumentality, and each
multi-state agency of which a state is a member will be regarded as a separate
issuer for the purpose of determining diversification.
    
 
   
MUNICIPAL SECURITIES--The term "municipal securities," as used in this
Prospectus means obligations issued by or on behalf of states, territories, and
possessions of the U.S. and the District of Columbia and their political
subdivisions, agencies, and instrumentalities, the interest on which is exempt
from federal income tax. An opinion as to the tax-exempt status of a municipal
security generally is rendered to the issuer by the issuer's counsel at the time
of issuance of the security. Neither the funds nor SM&R will review the
proceedings relating to the issuance of municipal obligations or the basis for
opinions of counsel.
    
 
                                       24
<PAGE>
   
Municipal securities are used to raise money for various public purposes such as
constructing public facilities and making loans to public institutions. Certain
types of municipal bonds are issued to obtain funding for privately operated
facilities. Further information on the maturity and funding classifications of
municipal securities is included in the Statement of Additional Information.
    
 
   
Yields on municipal securities vary, depending on a variety of factors,
including the general condition of the financial markets and of the municipal
securities market, the size of a particular offering, the maturity of the
obligation and the credit rating of the issuer. Like other interest-bearing
securities, the value of municipal securities changes as interest rates
fluctuate. For example, if interest rates increase from the time a security is
purchased, the security's value and sales price generally will be less than its
purchase cost. Conversely, if interest rates decline from the time a security is
purchased, the security's value and sales price may be greater than its purchase
cost. Generally, municipal securities of longer maturities produce higher
current yields than municipal securities with shorter maturities but are subject
to greater price fluctuation due to changes in interest rates, tax laws and
other general market factors. Lower-rated municipal securities generally produce
a higher yield with shorter maturities than higher-rated municipal securities
due to the perception of a greater degree of risk as to the ability of the
issuer to pay principal and interest.
    
 
   
The Tax Free Fund may purchase municipal bonds for which the payments of
principal and interest are secured by an escrow account of securities backed by
the full faith and credit of the U.S. government ("defeased") and municipal
securities whose principal and interest payments are insured by a commercial
insurance company as long as the underlying credit is investment grade (BBB or
better by S&P and Fitch and Baa or better by Moody's) ("insured"). The Tax Free
Fund may also purchase unrated securities of issuers which SM&R believes would
have been rated BBB or Baa had the issuer requested a rating from S&P, Fitch or
Moody's. Such implied investment grade rating will be determined by SM&R upon
its performance of a credit analysis of the issue and the issuer. Such credit
analysis may consist of a review of such items as the issuer's debt
characteristics, financial information, structure of the issue, liquidity of the
issue, quality of the issuer, current economic climate, financial adviser, and
underwriter. Insured and defeased bonds are
    
 
                                       25
<PAGE>
   
further described in the Statement of Additional Information. In general, these
types of municipal securities will not be treated as an obligation of the
original municipality for purposes of determining industry concentration.
    
 
   
PRIMARY FUND (FORMERLY NAMED AMERICAN NATIONAL PRIMARY FUND SERIES)
    
 
   
Commercial paper is short-term unsecured promissory notes issued by corporations
to finance short-term credit needs. Commercial paper is usually sold on a
discount basis and has a maturity at the time of issuance not exceeding nine
months. The Primary Fund will invest only in commercial paper which, at the date
of such investment, is rated in one of the two top categories by one or more of
the nationally recognized statistical rating organizations ("NRSROs") (See the
"Appendix" hereto for information about such ratings and such rating
organizations).
    
 
   
The Primary Fund, consistent with its investment objective, will attempt to
maximize yield by trying to take advantage of changing conditions and trends. It
may also attempt to take advantage of what are believed to be disparities in
yield relationships between different instruments. This procedure may increase
or decrease the portfolio yield depending upon the Primary Fund's ability to
correctly time and execute such transactions. Although the Primary Fund's assets
will be invested in securities with short maturities, the Primary Fund will
manage its portfolio as described above. (See "Portfolio Transactions and
Brokerage Allocation" in the Statement of Additional Information.)
    
 
   
OTHER INVESTMENTS--The Primary Fund may invest in (i) U.S. Government
Obligations (See the "Government Bond Fund" above for an explanation of U.S.
Government Obligations); (ii) other corporate obligations, such as bonds,
debentures or notes maturing in five (5) years or less at the time of purchase
which at the date of the investment are rated "A" or higher by an NRSRO; and
(iii) negotiable certificates of deposit of banks (including U.S. dollar
denominated obligations of foreign branches of U.S. banks and U.S. branches of
foreign banks and savings and loan associations and banker's acceptances of U.S.
banks which banks and savings and loan associations have total assets at the
date of investment (as of the date of their most recent published financial
statements) of at least
    
 
                                       26
<PAGE>
   
$1 billion (See "INVESTMENT OBJECTIVES AND POLICIES--Certificates of Deposit" in
the Statement of Additional Information for a description of the securities) and
(iv) repurchase agreements with respect to any type of instrument in which the
Primary Fund is authorized to invest even though the underlying instrument may
mature in more than two (2) years.
    
 
   
MONEY MARKET FUND
    
 
   
The Money Market Fund seeks to achieve its objective by investing in short-term
money market instruments determined to be of high quality by SM&R pursuant to
guidelines established by the Company's Board of Directors. The Money Market
Fund may invest in the following types of high quality debt obligations:
    
 
   
(1) U.S. GOVERNMENT OBLIGATIONS. U.S. Government Obligations consist of
marketable securities issued or guaranteed as to both principal and interest by
the United States Government or by its agencies and instrumentalities. (See
"Government Bond Fund" above for an explanation of U.S. Government Obligations).
    
 
   
(2) CERTIFICATES OF DEPOSIT. Certificates of deposit are negotiable certificates
issued against funds deposited in a commercial bank for a definite period of
time and earning a specified return. The Money Market Fund will invest only in
certificates of deposit of U.S. banks that have total assets in excess of $1
billion at the time of investment.
    
 
   
(3) BANKER'S ACCEPTANCES. Banker's acceptances are short-term instruments issued
by banks, generally for the purpose of financing imports or exports. An
acceptance is a time draft drawn on a bank by the importer or exporter to obtain
a stated amount of funds to pay for specific merchandise. The draft is then
"accepted" and is an irrevocable obligation of the issuing bank.
    
 
   
(4) COMMERCIAL PAPER. As discussed above under "Primary Fund," commercial paper
is short-term unsecured promissory notes issued by corporations to finance
short-term credit needs.
    
 
   
(5) BONDS AND NOTES. The Money Market Fund may invest in corporate bonds or
notes with a remaining maturity of one year or less.
    
 
   
(6) COLLATERALIZED MORTGAGE OBLIGATIONS. As discussed above under "Government
Bond Fund," CMOs are debt obligations collateralized by a portfolio or pool of
mortgages, mortgage-backed securities, or U.S. Government securities.
    
 
                                       27
<PAGE>
   
The Money Market Fund does not currently intend to invest in unrated securities,
securities subject to demand features, floating rate instruments, securities
subject to guarantees, and variable rate instruments.
    
 
   
The Money Market Fund limits its investments to those short-term securities that
the Board determines present minimal credit risk and that are "Eligible
Securities" when acquired by the Fund. As used in this Prospectus, "Eligible
Securities" means securities that are:
    
 
   
(a) rated in one of the two highest short-term rating categories, or
    
 
   
(b) whose issuer has another class of debt obligations rated in one of the two
    highest short-term rating categories.
    
 
   
To rely on a rating assigned to other debt obligations, those obligations must
be of comparable priority and security. All ratings must have been issued by the
requisite NRSROs. Currently, five organizations are NRSROs: Moody's, S&P, Fitch
Investors Service, Inc., Duff and Phelps, Inc., and Thomson BankWatch, Inc. A
discussion of the ratings categories of S&P and Moody's is contained in the
Appendix.
    
 
   
The Money Market Fund generally limits its investments in securities, as
follows:
    
 
   
  - It will not invest in securities issued by any one issuer, other than the
    U.S. Government, its agencies, or instrumentalities, in an amount that
    exceeds 5% of its total assets.
    
 
   
  - It will not invest more than 5% of its total assets in securities relying on
    ratings in the second highest rating category.
    
 
   
  - It will not invest more than 1% of its total assets in securities of any one
    issuer that rely on ratings in the second highest rating category.
    
 
   
(See "Investment Objectives and Policies" in the Statement of Additional
Information for a more detailed explanation of the investment categories.) The
Fund will maintain a dollar-weighted average portfolio maturity of 90 days or
less, and will not invest in any security with a remaining maturity of over 397
days (13 months).
    
 
   
Investments in money market instruments are subject to the ability of the issuer
to make payment at maturity. In addition, the Money Market Fund's performance
will vary depending on changes in short-term interest rates. However, both the
financial and market risks of
    
 
                                       28
<PAGE>
   
investment in the Money Market Fund may be expected to be less than for any
other Fund. By limiting its investments to Eligible Securities, the Money Market
Fund may not achieve as high a level of current income as a fund investing in
lower-rated securities.
    
 
   
RISK FACTORS
    
- -------------------------------------------------------------------
 
   
The following discussion relates to all four funds. The risk/return summary
located at the beginning of this prospectus identifies some specific risks
applicable to each individual fund.
    
 
   
GENERAL. There is no assurance that a fund will achieve its goals. Generally, if
the securities owned by a fund increase in value, the value of the shares of the
fund which you own will increase. Similarly, if the securities owned by a fund
decrease in value, the value of your shares will also go down. In this way, you
participate in any change in the value of the securities owned by a fund.
    
 
   
The risk inherent in investing in any fund is a risk common to any security.
That is, the value of a fund's shares will fluctuate in response to changes in
economic conditions, interest rates and the market's perception of the
underlying portfolio securities held by that fund. Each fund's share value
depends on general economic and securities market conditions, the investment
decisions of its management, and numerous other factors. All of these factors
are inherently uncertain and, in some cases, unforeseeable.
    
 
   
Any of the funds could lose money if the stock markets in general go down or if
the particular debt obligations purchased by a fund go down in value. In
addition, the funds could lose money if prevailing interest rates increase or if
the debt securities purchased by a fund are downgraded or defaulted upon.
    
 
   
DEBT SECURITIES RISKS. Debt securities are subject to change in their values due
to changes in prevailing interest rates. The magnitude of these fluctuations
will often be greater for longer-term debt securities than shorter-term debt
securities. When prevailing interest rates fall, the values of already-issued
debt securities generally rise. Accordingly, if interest rates go down after a
security is purchased, such security might be valued and/or sold at a price
greater than its cost. If interest rates were to drop dramatically, some of the
securities could be called and/or prepaid, requiring reinvesting in securities
at much lower yields.
    
 
                                       29
<PAGE>
   
On the other hand, when prevailing interest rates rise, the values of
already-issued debt securities generally fall. Accordingly, if interest rates
increase after a security is purchased, such security might be valued and/or
sold at a price less than its cost. In such circumstances, the value of existing
bonds decrease because the interest payments from existing bonds are less
attractive than new issues with higher interest rates and investors would lose
money if they liquidate holdings.
    
 
   
The funds could lose money if any bonds they own are downgraded in credit rating
or go into default. A moratorium, default, or other non-payment of interest or
principal when due could, in addition to affecting the market value and
liquidity of the particular security, affect the market value and liquidity of
other securities. A change in credit rating of an issuer can also affect the
bond's value, thus affecting the market value of the funds. However, the funds
invest predominately in investment grade bonds in order to minimize credit risk.
(See "Investment Objectives and Policies" for more information about the ratings
required for investments by each specific fund.) Moreover, substantial
redemptions of fund shares could require a fund to sell portfolio securities at
a time when a sale might not be favorable.
    
 
   
U.S. GOVERNMENT OBLIGATIONS. Investments in U.S. Government Obligations are not
all backed by the "full faith and credit" of the United States Government. Some
are backed only by the rights of the issuer to borrow from the U.S. Treasury and
others are supported only by the credit of the issuing instrumentality. No
assurance can be given that the U.S. Government would lend money to or otherwise
provide financial support to U.S. Government sponsored instrumentalities.
    
 
   
MARKET RISKS. Because the funds may invest in debt obligations which are traded
on securities exchanges, the value of each fund's portfolio will be affected by
changes in the stock markets. At times, the stock markets can be volatile and
stock prices can change substantially. This market risk will affect each fund's
net asset value per share, which will fluctuate as the values of each fund's
portfolio securities change. Prices do not always change uniformly or at the
same time and the various stock markets do not always move in the same direction
at the same time. Other factors specific to a particular company also affect the
price of that company's debt obligations (for example, poor earnings, loss of
major customers, or major litigation). The funds cannot always predict the
factors that will affect a security's
    
 
                                       30
<PAGE>
   
price. The funds, however, do attempt to limit market risk by diversifying their
investments. The funds diversify their investments by generally investing only a
small percentage of their assets in the debt obligations of any one company and
by not holding a substantial amount of the debt obligations of any one company.
    
 
   
REPURCHASE AGREEMENTS. In a repurchase agreement, a fund buys a security and
simultaneously sells it to the vendor for delivery at a future date. These
agreements are used primarily for cash purposes. A fund entering into a
repurchase agreement may lose money if the other party to the transaction fails
to pay the resale price on the delivery date. Such a default may delay or
prevent the fund from disposing of the underlying securities. The value of the
underlying securities may go down during the period in which the fund seeks to
dispose of them. Also, the fund may incur expenses while trying to sell the
underlying securities. Finally, the fund risks losing all or a part of the
income from the agreement.
    
 
   
OTHER RISKS. Each investor will be subject to all the risks normally attendant
to business operations, changes in general economic conditions, governmental
rules and fiscal policies, acts of God, and other factors beyond the control of
the funds' management.
    
 
   
YEAR 2000 RISKS. Many services provided to the funds and their shareholders
depend on the smooth functioning of computer systems. Many computer software
systems in use today cannot distinguish the year 2000 from the year 1900 because
of the way dates are encoded and calculated, referred to as the "Year 2000
Problem." The Year 2000 Problem could have a negative impact on handling
securities trades, payment of interest and dividends, pricing, and account
services. Like other mutual funds, financial and business organizations, and
individuals around the world, the funds could be adversely affected if the
computer systems used by SM&R (which acts as their investment adviser,
underwriter, custodian, and transfer agent) do not properly process and
calculate date-related information and data from and after January 1, 2000. SM&R
is taking steps to address the Year 2000 Problem with respect to the computer
systems that it uses and to obtain assurances that comparable steps are being
taken by any other service providers. At this time, however, there can be no
assurance that these steps will be sufficient to avoid any adverse impact on the
funds and their shareholders.

PURCHASES AND REDEMPTIONS
    
- -------------------------------------------------------------------
   
PURCHASING SHARES
    
 
   
You may purchase shares of a fund from registered representatives of SM&R, from
authorized broker-dealers, or directly from SM&R. Such purchases will be at the
offering price for such shares determined as and when provided below (See
"Pricing of Fund Shares"). SM&R will send you a monthly confirmation for any
month in which your account is active. You should carefully review the monthly
confirmation and promptly report any discrepancies to SM&R. You may make initial
and subsequent purchases directly through SM&R at the following address:
    
 
   
    Securities Management and Research, Inc.
    2450 South Shore Boulevard, Suite 400
    League City, Texas 77573
    
 
   
Certificates are not normally issued for shares of the funds in an effort to
minimize the risk of loss or theft. SM&R confirms investors' purchases and
credits such purchases to their accounts on the books maintained by SM&R.
Investors have the same rights of share ownership as they would if certificates
had been issued. Furthermore, a lost, stolen or destroyed certificate cannot be
replaced without obtaining a sufficient indemnity bond. The cost of such a bond
is borne by the investor and can be 2% or more of the value of the lost, stolen
or destroyed certificate.
    
 
   
OPENING AN ACCOUNT: To purchase shares, you must submit an account application
which includes the purchaser suitability form. If you would like to take
advantage of the electronic services available, please complete the electronic
transfer options section of the account application. Special forms are required
when establishing an IRA/ SEP or 403(b) plan. Please call Investor Services at
(800) 231-4639 and request special forms when establishing retirement plans.
    
 
   
MINIMUM PURCHASE REQUIREMENT: For Class Y shares of the Government Bond and Tax
Free Funds, the minimum initial investment requirement is $500,000. If the
investor is a group or institution specified in (a)-(d) of "Shares of the
Funds," the minimum initial investment is only $[     ]. All subsequent
investments must be at least $[     ]. For the Primary and Money Market Funds,
the minimum initial investment requirement is $[     ] and the minimum
    
 
                                       32
<PAGE>
   
amount of any subsequent purchase is $[     ]. The Company reserves the right to
reject any purchase.
    
 
   
PURCHASES BY MAIL: Make your check(s) payable to SM&R and send the check(s) to
the address indicated above. Please note that third party checks will not be
accepted to open a new account, except for IRA rollover checks that are properly
endorsed. If you make subsequent investments by mail, you must indicate your
name, account number, and the name of the fund, and the class if applicable,
being purchased. You may use the remittance slip attached to the confirmation
statement.
    
 
   
PURCHASES BY WIRE: TO ENSURE PROPER CREDITING OF A WIRE INVESTMENT, YOU MUST
HAVE AN EXECUTED ACCOUNT APPLICATION AND PURCHASER SUITABILITY FORM ON FILE WITH
THE TRANSFER AGENT. You may then wire your investment to The Moody National Bank
of Galveston ("Moody National Bank") by providing the following instructions to
your bank:
    
 
   
    The Moody National Bank of Galveston ABA #113100091
    Securities Management and Research, Inc. #035 868 9
    Name of Class, if applicable, and Fund (E.G., Class Y of the
      Government Bond Fund)
    Fund Account Number (number appears on confirmation
      statement)
    Investor's Name (E.G., First National Bank)
    
 
   
PURCHASES BY EXCHANGE: Call Investor Services if you have established telephone
exchange privileges on your account. See "Special Purchase Plans and
Services--Exchange Privilege" for procedures and additional information relating
to telephone exchanges. For limitations on exchanges, see "Excessive Trading"
also under "Special Purchase Plans and Services."
    
 
   
PRICING OF FUND SHARES
    
 
   
GENERAL (HOW SHARES ARE PRICED). We determine each fund's offering price once
each business day. The offering price equals a fund's net asset value plus the
sales charge, if any. You may purchase shares offered in this prospectus without
a sales charge. Accordingly, the offering price for shares offered in this
prospectus is that fund's (or class') net asset value.
    
 
   
EFFECTIVE DATE OF PURCHASES AND REDEMPTIONS (WHEN SHARES ARE PRICED).
Calculation of net asset value is made once each business day at the
    
 
                                       33
<PAGE>
   
close of the New York Stock Exchange (currently 3:00 p.m. Central Time).
Accordingly, the price you pay or receive for shares of a fund depends, in part,
on the day and time you make your purchase or redemption. On any business day,
we will execute purchases and redemptions at the applicable price determined
that day if:
    
 
   
  - SM&R receives your order in proper form prior to the close of the Exchange;
    
 
   
  - a securities dealer having a dealer contract with SM&R receives your order
    prior to the close of the Exchange and reports your order to SM&R prior to
    SM&R's close of business (currently 4:30 p.m. Central Time) on the same day;
    or
    
 
   
  - for purchases, Moody National Bank receives your purchase payment by bank
    wire and reports it to SM&R prior to the close of the Exchange.
    
 
   
If we receive your order after the close of the Exchange, on customary national
business holidays, or on an SM&R business holiday, we will execute your purchase
or redemption at the price determined on the next business day. In unusual
circumstances, any fund may temporarily suspend the processing of sell requests,
or may postpone payment of proceeds for up to three business days or longer, as
allowed by federal securities laws.
    
 
   
SM&R BUSINESS HOLIDAYS. SM&R's business holidays are:
    
 
   
  - Good Friday
    
 
   
  - Memorial Day
    
 
   
  - Independence Day
    
 
   
  - Labor Day
    
 
   
  - Thanksgiving Day
    
 
   
  - the day after Thanksgiving
    
 
   
  - Christmas Day
    
 
   
  - New Years Day
    
 
   
In addition, SM&R business holidays include the weekday preceding Christmas Day,
or, if Christmas Day is a Saturday, the preceding Thursday and Friday. If
Christmas Day is a Sunday, the following Monday also will be a business holiday.
If New Years Day is a Saturday, the preceding Friday will be a business holiday,
and if New Years Day is a Sunday, the following Monday will be a business
holiday.

SPECIAL PURCHASE PLANS AND SERVICES
    
 
   
The Company offers services and plans designed to facilitate investment in the
funds. At this time, there is no charge to you for these services. The Company
may impose fees for such services in the future. Be aware, however, that if you
elect to participate in the ACH plan described below, you should check with your
financial institution for any additional charges imposed for this service. For
additional information contact your registered representative or SM&R. A
shareholder considering any of the plans or services described below should
consult a tax advisor before beginning a plan.
    
 
   
ELECTRONIC TRANSFERS (ACH). The electronic transfer option allows you to move
money between your account(s) and your bank, savings and loan, or credit union
account using the Automated Clearing House ("ACH") network. To arrange for
electronic transfers, complete the relevant section of the account application
at the time you open your account and specify the type of service or services
desired. Attach a voided, pre-printed check or deposit slip from your checking,
savings and loan, or credit union account. PASSBOOK SAVINGS ACCOUNTS ARE NOT
ELIGIBLE FOR THE ELECTRONIC TRANSFER OPTION. ADDITIONALLY, YOUR BANK MUST BE A
MEMBER OF THE AUTOMATED CLEARING HOUSE (ACH) NETWORK FOR YOU TO TAKE ADVANTAGE
OF THIS SERVICE. You will receive a confirmation verifying initialization of the
electronic transfer option and may begin conducting transactions in your
account(s) under this option approximately 20 calendar days after receipt of the
verification notice from SM&R. If you elect this option after your account is
established, it may be necessary for you to obtain a signature guarantee for all
individuals named on the account(s).
    
 
   
TELEPHONE SERVICES. You can take advantage of this service by completing the
appropriate sections of the account application when opening your account.
Through this service, you will be able to purchase by ACH, redeem and exchange
shares on those accounts for which you have an executed account application on
file, and have received written verification from SM&R that the service has been
initialized as explained under Electronic Transfers above. If this option is
elected after your account is established, it may be necessary for you to obtain
a signature guarantee for all individuals named on the account(s). We permit
transfers by telephone from a joint account only to another joint account
registered in the identical names. There may be additional restrictions on
telephone transactions by joint account owners. Contact your registered
representative
    
 
                                       35

for more information. PLEASE NOTE THAT THE TELEPHONE REDEMPTION OPTION IS NOT
AVAILABLE TO RETIREMENT PLANS.
    
 
   
The funds have implemented the following security procedures intended to protect
your account from losses resulting from unauthorized or fraudulent telephone
instructions: The caller must know:
    
 
   
 (i) the name of the fund or funds;
    
   
 (ii) all digits of the account number;
    
   
(iii) the exact name and address used in the registration(s); and
    
   
 (iv) the Social Security or Employer Identification Number listed on the
      account(s).
    
 
   
Additionally, we record all telephone transactions for your protection.
    
 
   
Neither the funds nor SM&R will be responsible for the authenticity of
transaction instructions received by telephone which comply with the current
security procedures and other requirements. SM&R believes that such security
procedures and other requirements are reasonable and, if followed, you should
bear the risk of any losses resulting from unauthorized or fraudulent telephone
transactions on your account(s).
    
 
   
AUTOMATIC INVESTMENT PLAN. Through this plan, a specified amount is
electronically transferred (via ACH) from your bank account and invested
monthly, bi-monthly, quarterly, or annually into the designated fund(s) at the
applicable offering price determined on the date of the electronic transfer.
    
 
   
WEALTH ACCUMULATION ACCOUNT. Shareholders having account balances of at least
$2,500 in the Money Market Fund may open a Wealth Accumulation Account, which
will provide them with an automatic dollar cost averaging plan. Automatic
monthly purchases of the shares of other funds managed by SM&R may be made by
exchanges from the shareholder's Money Market Fund Wealth Accumulation Account.
Purchases of the other funds must be at least $50 and, unless terminated by the
shareholder, will continue as long as the balance of the Money Market Fund
Wealth Accumulation Account is sufficient. Additional investments may be made to
a Money Market Fund account designated as a Wealth Accumulation Account to
extend the purchase period under the plan. However, if additional investments
are received by SM&R less than ten (10) business days prior to the 20th of the
month, such investments will not be available
    
 
                                       36
<PAGE>
   
for use under the Wealth Accumulation Account until the 20th of the following
month. If the 20th of the month is an SM&R holiday, the purchase will be
processed on the next business day.
    
 
   
Purchases made will be subject to the applicable sales charge of the fund whose
shares are being purchased. Changes in amounts to be purchased, the funds being
purchased, and termination of a Wealth Accumulation Account will be made within
five (5) business days after written instructions are received by SM&R in proper
form (I.E., signed by the owner(s) of record exactly as registered).
    
 
   
Shareholders' rights to make additional investments, to exchange shares, and to
redeem shares in the Money Market Fund and any of the funds managed by SM&R are
not affected by a shareholder's participation in a Wealth Accumulation Account.
However, check writing privileges and expedited redemption by telephone are not
available for the Money Market Fund accounts designated as a part of the Wealth
Accumulation Account.
    
 
   
Primary Fund shareholders that opened a Primary Fund Wealth Accumulation Account
prior to December 31, 1998 will be permitted to continue using the Account
subject to the terms applicable to a Money Market Fund Wealth Accumulation
Account, described above.
    
 
   
EXCHANGE PRIVILEGE. As an investor in a fund, you are permitted to exchange
shares that you own in a fund with shares of another fund managed by SM&R
without the payment of an exchange fee, subject to certain conditions. EXCHANGES
BETWEEN A FUND AND ANOTHER FUND MANAGED BY SM&R ARE AVAILABLE ONLY IN STATES
WHERE THE APPLICABLE FUNDS ARE REGISTERED AND THE EXCHANGE MAY BE LEGALLY MADE.
YOU SHOULD CONTACT SM&R TO DETERMINE WHETHER A FUND IS REGISTERED IN A
PARTICULAR STATE.
    
 
   
GOVERNMENT BOND FUND AND TAX FREE FUND. You may exchange Class Y shares that you
own in the Government Bond or Tax Free Fund, without an exchange fee, for shares
of the corresponding class of another fund managed by SM&R. You also may
exchange your Class Y shares for shares of the Money Market or Primary Fund,
provided that you meet any minimum investment requirement for the shares you
wish to acquire. You may exchange Class Y shares of the Government Bond or Tax
Free Fund for shares of another class of that fund, provided that you pay any
sales charge applicable to the acquired shares.
    
 
                                       37
<PAGE>
   
PRIMARY FUND AND MONEY MARKET FUND. You may exchange shares you own in the
Primary Fund for shares of the Money Market Fund, and vise versa. You may
exchange shares you own in the Primary or Money Market Fund for shares of a
class of another fund managed by SM&R, provided you pay any sales charge
applicable to the acquired shares.
    
 
   
You may acquire, through an exchange, shares of a class with a contingent
deferred sales charge. If you redeem those shares, the relevant contingent
deferred sales charge, if any, will be calculated from the date that you
initially purchased the original shares, rather than from the date of exchange.
    
 
   
You may request an exchange by telephone or in writing. In order to exchange
shares, the following requirements must be met:
    
 
   
(a) the exchange must be made between accounts having identical registrations
    and addresses;
    
 
   
(b) the shares of the fund acquired through exchange must be qualified for sale
    in the state in which you reside;
    
 
   
(c) the dollar amount of the exchange must meet the minimum investment
    requirement applicable to the shares of the fund that you would acquire
    through the exchange;
    
 
   
(d) SM&R must have received full payment for the shares being exchanged;
    
 
   
(e) your account must have been coded to reflect your certified taxpayer
    identification number, or, if applicable, an appropriate Internal Revenue
    Service Form W-8 (certificate of foreign status) or Form W-9 (certifying
    exempt status);
    
 
   
(f) any shares that you wish to exchange must have been held for at least ten
    (10) business days;
    
 
   
(g) certificates representing shares, if any, are returned before such shares
    are exchanged; and
    
 
   
(h) you have received a prospectus for the shares you receive in the exchange.
    
 
   
The exchange privilege is not an option or right to purchase shares but is
permitted under the respective policies of the participating funds, and may be
modified or discontinued by the participating funds or by SM&R at any time. ANY
GAIN OR LOSS REALIZED ON AN
    
 
                                       38
<PAGE>
   
EXCHANGE OR RE-EXCHANGE MAY BE RECOGNIZED FOR FEDERAL AND STATE INCOME TAX
PURPOSES. YOU SHOULD CONSULT YOUR TAX ADVISOR FOR THE TAX TREATMENT AND EFFECT
OF EXCHANGES.
    
 
   
EXCESSIVE TRADING. Frequent trades, involving either substantial fund assets or
a substantial portion of your account or accounts controlled by you, can disrupt
management of the Company and raise the Company's expenses. We currently define
"excessive trading" as exceeding one purchase and sale involving the same fund
within any 120-day period.
    
 
   
For example, you are in Fund X. You can move substantial assets from Fund X to
Fund Y and, within the next 120 days, sell your shares in Fund Y to return to
Fund X or move to Fund Z. If you exceed the number of trades described above,
you may be barred indefinitely from further transactions between the
participating funds.
    
 
   
There are two types of transactions exempted from the excessive trading
guidelines. They are (1) redemptions that are not part of exchanges and (2)
systematic purchases or redemptions.
    
 
   
RETIREMENT PLANS
    
 
   
The following retirement plans may be funded with Class Y shares of the
Government Bond Fund or with shares of the Primary and Money Market Funds:
    
 
   
  - Individual Retirement Accounts (IRAs), which include traditional IRAs, Roth
    IRAs, Education IRAs, and SIMPLE IRAs,
    
 
   
  - Simplified Employee Pension Plans (SEPs),
    
 
   
  - 403(b) Custodial Accounts (TSAs), and
    
 
   
  - corporate retirement plans.
    
 
   
These plans allow you to shelter investment income from federal income tax while
saving for retirement. Information concerning IRAs and TSAs, and the forms
necessary to adopt such plans, can be obtained by contacting your registered
representative or calling SM&R. A regular fund application should be used when
establishing a corporate retirement plan. In connection with retirement plans,
the minimum initial purchase for each fund is $100. (See "Purchasing Shares" for
the minimum initial and subsequent purchase requirements.) SM&R acts as trustee
or custodian for IRAs, SEPs, and TSAs for the Company. An annual custodial fee
of $7.50 per account
    
 
                                       39
<PAGE>
   
will be charged for any part of a calendar year in which an investor has an IRA,
SEP, or TSA in the Company and will be automatically deducted from each account.
An individual considering a retirement plan may wish to consult with an attorney
or tax adviser.
    
 
   
Because IRAs, SEPs, TSAs, and other qualified plans are exempt from federal
income tax, they will be unable to benefit from the general tax-exempt nature of
the Tax Free Fund. Accordingly, the Tax Free Fund is not generally considered to
be suited for such plans or persons.
    
 
   
DIVIDENDS, DISTRIBUTIONS, AND TAXES
    
 
   
DIVIDENDS.
    
 
   
GOVERNMENT BOND AND TAX FREE FUNDS. The Government Bond and Tax Free Funds will
declare and pay dividends from net investment income monthly and net realized
short-term or long-term capital gains, if any, annually. In order to be entitled
to a dividend, an investor must have acquired shares of a fund prior to the
close of business on the record date. A shareholder should be cautioned,
however, before purchasing shares of a fund immediately prior to a distribution.
Dividends and distributions paid by the funds have the effect of reducing net
asset value per share on the record date by the amount of the payment.
Therefore, a dividend or distribution of record shortly after the purchase of
shares by an investor represents, in substance, a return of capital.
    
 
   
PRIMARY AND MONEY MARKET FUNDS. At 3:00 p.m. Central Time, on each day that the
Exchange is open for trading other than SM&R's business holidays described
above, the Primary and Money Market Funds each will declare a dividend of all of
its net investment income to shareholders of record on that date. Such dividends
will be paid monthly.
    
 
   
DIVIDEND REINVESTMENTS. Dividends and capital gains will be automatically
reinvested at net asset value in additional shares of the fund making such
distribution unless SM&R is instructed otherwise in writing. Distributions not
reinvested are paid by check or transmitted to your bank account through an ACH
transaction, if elected. If the Postal Service cannot deliver your check, or if
your check remains uncashed for six months, the funds reserve the right to
reinvest your distribution check in your account at the net asset value on the
business day of the reinvestment and to reinvest all future distributions
    
 
                                       40
<PAGE>
   
in shares of the applicable fund(s). Dividends and capital gains declared in
December to shareholders of record in December and paid the following January
will be taxable to shareholders as if received in December. This is a convenient
way to accumulate additional shares and maintain or increase the shareholder's
earning base. Of course, any shares so acquired remain at market risk.
    
 
   
Shareholders have the right to change their election with respect to the receipt
of distributions by notifying SM&R in writing, but any such change will be
effective only as to distributions for which the record date is seven or more
business days after SM&R has received the shareholder's written request.
    
 
   
TAXABILITY OF DIVIDENDS. Dividends you receive from the Government Bond,
Primary, and Money Market Funds, whether reinvested or taken as cash, are
generally considered taxable. A fund's long-term capital gains distributions are
taxable as capital gains; dividends from other sources are generally taxable as
ordinary income. Some dividends paid in January may be taxable as if they had
been paid the previous December. The Form 1099 that is mailed to you every
January details your dividends and their federal tax category, although you
should verify your tax liability with your tax professional.
    
 
   
The Tax Free Fund intends to distribute tax-exempt dividends that shareholders
may exclude from their gross income for federal income tax purposes. However,
the Tax Free Fund may invest a portion of its assets in securities that generate
income that is not exempt from federal or state income tax. Income exempt from
federal tax may be subject to state and local income tax. Any capital gains
distributed by the Tax Free Fund may be taxable. Also, you should also keep in
mind that certain income from the Tax Free Fund may be subject to the federal
alternative minimum tax.
    
 
   
BACKUP WITHHOLDING. Backup withholding of federal income tax may be applied at
the rate of 31% from taxable dividends, distributions, and redemption proceeds
(including exchanges) if you fail to furnish the Company with a correct and
properly certified Social Security or Employer Identification Number when you
sign your application, or if you underreport your income to the Internal Revenue
Service.
    
 
   
TAXABILITY OF TRANSACTIONS. Any time you sell or exchange shares, it is
considered a taxable event for you. Depending on the purchase price and the sale
price of the shares you sell or exchange, you may have a gain or a loss on the
transaction. You are responsible for any tax
    
 
                                       41
<PAGE>
   
liabilities generated by your transactions. You should consult with a tax
advisor concerning the tax reporting requirements in effect on the redemption or
exchange of such shares.
    
 
   
REDEEMING SHARES
    
 
   
You can redeem fund shares at the net asset value determined on the date the
request is received by SM&R in proper form. A redemption request must be
addressed to Securities Management and Research, Inc., 2450 South Shore
Boulevard, Suite 400, League City, Texas 77573.
    
 
   
If uncertain of the redemption requirements, investors should call Investor
Services or write SM&R. Payment will be made as soon as practicable and normally
within seven days after receipt of a redemption request in proper form. We
currently charge a fee in the amount of $8.00 for redemptions by wire under
$5,000.
    
 
   
If the shares being redeemed were purchased by wire, certified check, money
order, or other immediately available funds, redemption proceeds will be mailed
no later than the seventh calendar day following receipt. For shares purchased
by a personal check or ACH transfer, SM&R will process your redemption but will
generally delay sending you the proceeds for up to ten (10) business days to
allow the check or transfer to clear.
    
 
   
TELEPHONE REDEMPTIONS. You may request redemptions by telephone if you have
completed the account application and requested this option. This redemption
feature can only be used if:
    
 
   
(a) the redemption proceeds are to be mailed to the address of record or wired
    to the pre-authorized bank account indicated on the account application;
    
 
   
(b) there has been no change of address of record or pre-authorized bank account
    within the preceding 30 business days;
    
 
   
(c) the shares to be redeemed are not in certificate form;
    
 
   
(d) the security procedures discussed under "Special Purchase Plans And
    Services--Exchange Privilege" have been met; and
    
 
   
(e) the proceeds of the redemption do not exceed $25,000.
    
 
   
SYSTEMATIC WITHDRAWAL PLAN. The Company has a Systematic Withdrawal Plan
("Withdrawal Account"), which permits shareholders having an account value of
$5,000 or more to automatically withdraw
    
 
                                       42
<PAGE>
   
a minimum of $50 monthly or each calendar quarter on or about the 20th of the
applicable month. Shareholders maintaining a Withdrawal Account may elect to
have the withdrawal proceeds automatically deposited in their pre-authorized
bank account via an ACH transaction. This is accomplished by completing the
relevant section of the account application and returning it to SM&R. See
"Special Purchase Plans and Services--Electronic Transfers" for additional
information. Dividends and capital gains distributions will automatically be
reinvested in additional shares at net asset value. As with other redemptions, a
withdrawal is a sale for federal income tax purposes. The Systematic Withdrawal
Plan will automatically terminate if all shares are liquidated or withdrawn from
the account. Certificates are not issued for shares held in a Withdrawal Account
and certificates held, if any, must be surrendered when shares are transferred
to a Withdrawal Account. No account covered by a Letter of Intent can be changed
to a Systematic Withdrawal Plan until such time as the Letter of Intent is
fulfilled or terminated, nor can an account under a Systematic Withdrawal Plan
be placed under a Letter of Intent.
    
 
   
For further information about the "Systematic Withdrawal Plan," contact a
registered representative or SM&R.
    
 
   
"PROPER FORM" means the request for redemption must include:
    
 
   
(1) your share certificates, if issued;
    
 
   
(2) your letter of instruction or a stock assignment specifying the fund,
    account number, and number of shares or dollar amount to be redeemed. Both
    share certificates and stock powers, if any, must be endorsed and executed
    exactly as the fund shares are registered. It is suggested that certificates
    be returned by certified mail for your protection;
    
 
   
(3) any required signature guarantees (see "Signature Guarantees" below); and
    
 
   
(4) other supporting legal documents, if required in the case of estates,
    trusts, guardianships, divorce, custodianships, corporations, partnerships,
    pension or profit sharing plans, retirement plans, and other organizations.
    
 
   
Please keep in mind that as a shareholder, it is your responsibility to ensure
that all requests are submitted to the Company's transfer agent in proper form
for processing.
    
 
                                       43
<PAGE>
   
SIGNATURE GUARANTEES. A signature guarantee verifies the authenticity of your
signature. Signature guarantees are required when:
    
 
   
(1) the proceeds of the redemption exceed $25,000;
    
 
   
(2) the proceeds (in any amount) are to be paid to someone OTHER THAN the
    registered owner(s) of the account;
    
 
   
(3) the proceeds (in any amount) are to be sent to any address OTHER THAN the
    shareholder's address of record, pre-authorized bank account or exchanged to
    one of the other funds managed by SM&R; or
    
 
   
(4) the Company or its transfer agent believes a signature guarantee would
    protect against potential claims based on the transfer instructions,
    including, when the authority of a representative of a corporation,
    partnership, association, or other entity has not been established to the
    satisfaction of the Company or transfer agent.
    
 
   
You should be able to obtain an acceptable signature guarantee from a bank,
broker, dealer, municipal securities dealer or broker, government securities
dealer or broker, credit union, national securities exchange, or registered
securities association. WITNESSING OR NOTARIZATION IS NOT SUFFICIENT.
    
 
   
TEXAS OPTIONAL RETIREMENT PROGRAM. You may not redeem shares of the Government
Bond Fund, Primary Fund, and Money Market Fund in any account established under
the Texas Optional Retirement Program, unless SM&R receives satisfactory
evidence from the state that one of the following conditions exist:
    
 
   
(1) death of the employee;
    
 
   
(2) termination of service with the employer; or
    
 
   
(3) retirement of employee.
    
 
   
CHECK WRITING OPTION. Check writing is available in the Money Market Fund to
investors having an account value of $1,000 or more. $250 is the minimum check
amount under the check writing option. This option is not available on IRAs,
SEPs, or TSAs. Shareholders wishing to avail themselves of this option must
complete the check writing option signature card in the Prospectus. After
obtaining specimen signatures and the fully executed card, SM&R will order
checks and arrange for the shareholder's checks to be honored by a bank.
    
 
                                       44
<PAGE>
   
Investments made by personal check or third party check will be held for fifteen
(15) business days following the investment during which time checks may not be
drawn on the amount of such investment. This service may be terminated or
suspended or additional charges may be imposed for this service. Shareholders
will be provided the initial checkbook free of charge. There will be a $5 fee
for re-orders. Shareholders will be allowed to write ten (10) checks free each
calendar quarter.
    
 
   
When a check is presented for payment, SM&R, as the shareholder's agent, will
cause each fund to redeem a sufficient number of full and fractional shares to
cover the amount of the check. Shareholders will continue to be entitled to
dividends on their shares up to the time the check is presented to SM&R for
payment. If the amount of the check is greater than the value of the shares held
in the shareholder's account for more than fifteen (15) business days at the
time the check is presented for payment, the check will be returned to the payee
as not being covered by sufficient funds, and the shareholder will be subject to
extra charges as a result.
    
 
   
Primary Fund shareholders that had check writing privileges prior to December
31, 1998 will be permitted to continue writing checks on the Primary Fund
subject to the terms applicable to the Money Market Fund described above.
SHAREHOLDERS USING THE PRIMARY FUND CHECK WRITING OPTION SHOULD BE AWARE THAT
WRITING A CHECK IS A REDEMPTION OF SHARES. THOSE SHARES MAY BE WORTH LESS WHEN
THE CHECK IS PRESENTED FOR PAYMENT THAN WHEN THE CHECK WAS WRITTEN.
    
 
   
REDEMPTION OF SMALL ACCOUNTS. The Company reserves the right to redeem shares in
any account (which will be promptly paid to the shareholder) if, due to your
redemptions, the value of the account falls below $100 in the case of the
Government Bond and Tax Free Funds or $1,000 in the case of the Primary and
Money Market Funds. You will be notified that the value of your account is less
than the required minimum indicated above and allowed at least 60 days to make
an additional investment to increase the value of your account above the
required minimum. The Board of Directors may, from time to time, change such
required minimum investment.
    
 
   
RIGHTS RESERVED BY THE COMPANY. The Company, acting through its transfer agent,
reserves the right:
    
 
   
  - to waive or lower investment minimums;
    
 
                                       45
<PAGE>
   
  - to accept initial purchases by telephone from a registered representative;
    
 
   
  - to refuse any purchase order;
    
 
   
  - to cancel or rescind any purchase or exchange at any time prior to receipt
    by the shareholder of written confirmation or, if later, within five (5)
    business days of the transaction;
    
 
   
  - to freeze an account and suspend account services when notice has been
    received of a dispute involving the account owners or other parties or there
    is reason to believe a fraudulent transaction may occur;
    
 
   
  - to restrict or refuse the use of faxed redemptions where there is a question
    as to the validity of the request or proper documents have not been
    received;
    
 
   
  - to otherwise modify the conditions of purchase and any services at any time;
    or
    
 
   
  - to act on instructions not believed to be genuine.

THE FUNDS AND MANAGEMENT
    
- -------------------------------------------------------------------
 
   
INVESTMENT ADVISOR
    
 
   
The Company's Board of Directors has delegated to Securities Management and
Research, Inc. ("SM&R"), the funds' investment adviser, the management of the
funds' day-to-day business and affairs. In addition, SM&R invests the funds'
assets, provides administrative services, and serves as transfer agent,
custodian, dividend paying agent, and underwriter.
    
 
   
SM&R is a wholly-owned subsidiary of American National Insurance Company
("American National"). SM&R was incorporated in 1964 and has managed mutual
funds since 1966. SM&R does and may, from time to time, serve as investment
adviser to other clients including employee benefit plans, other investment
companies, banks, foundations and endowment funds.
    
 
   
Under the Advisory Agreements with the Company, SM&R is paid an investment
advisory fee, which is calculated separately for each fund, as compensation for
its services. The agreement provides that SM&R will receive advisory fees as set
forth below.
    
 
   
GOVERNMENT BOND FUND AND TAX FREE FUND. We deduct an investment advisory fee
from the value of the shares each day. We calculate this fee for the Government
Bond and Tax Free Funds at the annual rate as follows:

</TABLE>
    
 
   
MONEY MARKET FUND AND PRIMARY FUND. For the Money Market and Primary Funds, we
calculate the investment advisory fee at the annual rate of 0.50% of each fund's
average daily net asset value.
    
 
   
After applicable fee waivers, SM&R received total advisory fees from the
Government Bond Fund, Tax Free Fund, and Primary Fund for the fiscal year ended
August 31, 1998 which represented [____]%, [____]%, and [____]%, respectively,
of each such fund's average daily

net assets. The Money Market Fund was not in operation during the fiscal year
ended August 31, 1998.
    
 
   
ADMINISTRATIVE SERVICES
    
 
   
Under its Administrative Service Agreement with the Company, SM&R also receives
an administrative service fee from each fund at the annual rate of average daily
net asset values as follows:

REIMBURSEMENTS AND WAIVERS
    
 
   
SM&R has agreed to pay (or to reimburse each fund for) each fund's regular
operating expenses in excess of 1.25% (0.35% for the Money Market Fund) per year
of such fund's average daily net assets. Regular operating expenses include the
advisory fee and administrative service fee, if any, paid to SM&R, but do not
include 12b-1 fees, class-specific expenses, interest, taxes, commissions, and
other expenses incidental to portfolio transactions. SM&R received
administrative service fees of [___]% for the Government Bond Fund; [___]% for
the Primary Fund; and [___]% for the Tax Free Fund for the fiscal year ended
August 31, 1998 of each fund's average daily net assets. The Money Market Fund
was not in operation during the fiscal year ended August 31, 1998.
    
 
   
In order to improve the yield and total return of any fund of the Company, SM&R
may from time to time voluntarily waive or reduce all or any portion of its
advisory fee, administrative fee, and/or assume certain or all expenses of any
fund of the Company while retaining its ability to be reimbursed for such fees
prior to the end of the fiscal year. Fee waivers and/or reductions, other than
those stated in the Administrative Service Agreement, may be rescinded by SM&R
at any time without notice to investors. SM&R has agreed to continue to waive
the advisory fee for the Tax Free Fund and reimburse expenses incurred by the
Government Bond and Primary Funds to the extent that regular operating expenses
exceed average daily net assets as follows: 0.80% for the Primary Fund and 1.00%
for the Government Bond Fund.

FINANCIAL HIGHLIGHTS                                        GOVERNMENT BOND FUND
    
- -------------------------------------------------------------------
 
   
The following financial highlights table is intended to help you understand the
Government Bond Fund's financial performance for the past five years. Certain
information reflects financial results for a single share outstanding throughout
each period shown. The total returns in the table represent the rate that an
investor would have earned (or lost) on an investment in the Government Bond
Fund (assuming reinvestment of all dividends and distributions) prior to
addition of multiple classes of shares. This information is derived from the
financial statements of the Government Bond Fund which for the years ended
through August 31, 1997 have been audited by KPMG Peat Marwick LLP and for the
year ended August 31, 1998 has been audited by Tait, Weller & Baker, CPA. Each
independent auditor's report, along with the Government Bond Fund's financial
statements, are incorporated by reference into the Statement of Additional
Information, which is available upon request.

The following financial highlights table is intended to help you understand the
Tax Free Fund's financial performance since inception. Certain information
reflects financial results for a single share outstanding throughout each period
shown. The total returns in the table represent the rate that an investor would
have earned (or lost) on an investment in the Tax Free Fund (assuming
reinvestment of all dividends and distributions) prior to addition of multiple
classes of shares. This information is derived from the financial statements of
the Tax Free Fund which for the years ended through August 31, 1997 have been
audited by KPMG Peat Marwick LLP and for the year ended August 31, 1998 has been
audited by Tait, Weller & Baker, CPA. Each independent auditor's report, along
with the Tax Free Fund's financial statements, are incorporated by reference
into the Statement of Additional Information, which is available upon request.

APPENDIX
    
 
   
(Description of Ratings Used in Prospectus)
    
- -------------------------------------------------------------------
 
   
BOND RATINGS
    
 
   
DESCRIPTION OF STANDARD & POOR'S CORPORATION'S BOND RATING:
    
 
   
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 obligations 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 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, which
       could lead to the obligor's inadequate capacity to meet its financial
       commitment on the obligation.
    
 
   
B     An obligation rated "B" is more vulnerable to nonpayment than obligations
       rated "BB," but the obligor currently has the capacity to meet its
       financial commitment on the obligation.
    
 
                                      A-1
<PAGE>
   
       Adverse business, financial, or economic conditions will likely impair
       the obligor's capacity or willingness to meet its financial commitment on
       the obligation.
    
 
   
DESCRIPTION OF MOODY'S INVESTOR'S SERVICE, INC.'S BOND RATINGS:
    
 
   
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-edge." 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,
       fluctuation of protective elements may be of greater amplitude, or there
       may be other elements present which make the long-term risks appear
       somewhat greater than in Aaa securities.
    
 
   
A     Bonds which are rated "A" possess many favorable investment attributes and
       are to be considered as upper medium grade obligations. Factors giving
       security to principal and interest are considered adequate but elements
       may be present which suggest a susceptibility to impairment sometime in
       the future.
    
 
   
Baa   Bonds which are rated "Baa" are considered as medium grade obligations,
       I.E., they are neither highly protected nor poorly secured. Interest
       payments and principal security appear adequate for the present, but
       certain protective elements may be lacking or may be characteristically
       unreliable over any great length of time. Such bonds lack outstanding
       investment characteristics and in fact have speculative characteristics
       as well.
    
 
   
Ba    Bonds which are rated "Ba" are judged to have speculative elements; their
       future cannot be considered as well assured. Often the protection of
       interest and principal payments may be very moderate and thereby not well
       safeguarded during both good and bad times over the future. Uncertainty
       of position characterizes bonds in this class.
    
 
                                      A-2
<PAGE>
   
B     Bonds which are rated "B" generally lack characteristics of the desirable
       investment. Assurance of interest and principal payments or of
       maintenance of other terms of the contract over any long period of time
       may be small.
    
 
   
DESCRIPTION OF FITCH INVESTORS SERVICE BOND RATINGS:
    
 
   
AAA  Obligations which have the highest rating assigned by Fitch IBCA on its
       national rating scale for that country. This rating is automatically
       assigned to all obligations issued or guaranteed by the sovereign state.
       Capacity for timely repayment of principal and interest is extremely
       strong, relative to other obligors in the same country.
    
 
   
AA   Obligations for which capacity for timely repayment of principal and
       interest is very strong relative to other obligors in the same country.
       The risk attached to these obligations differs only slightly from the
       country's highest rated debt.
    
 
   
A     Obligations for which capacity for timely repayment of principal and
       interest is strong relative to other obligors in the same country.
       However, adverse changes in business, economic or financial conditions
       are more likely to affect the capacity for timely repayment than for
       obligations in higher rated categories.
    
 
   
BBB  Obligations for which capacity for timely repayment of principal and
       interest is adequate relative to other obligors in the same country.
       However, adverse changes in business, economic or financial conditions
       are more likely to affect the capacity for timely repayment than for
       obligations in higher rated categories.
    
 
   
MUNICIPAL NOTE RATINGS
    
 
   
DESCRIPTION OF MOODY'S INVESTOR SERVICE INC.'S MUNICIPAL NOTE RATINGS:
    
 
   
MIG 1/VMIG 1 This designation denotes best quality. There is present strong
                protection by established cash flows, superior liquidity support
                or demonstrated broad-based access to the market refinancing.
    
 
                                      A-3
<PAGE>
   
MIG 2/VMIG 2 This designation denotes high quality. Margins of protection are
                ample although not so large as in the preceding group.
    
 
   
MIG 3/VMIG 3 This designation denotes favorable quality. All security elements
                are accounted for but there is lacking the undeniable strength
                of the preceding grades. Liquidity and cash flow protection may
                be narrow and market access for refinancing is likely to be less
                well established.
    
 
   
MIG 4/VMIG 4 This designation denotes adequate quality. Protection commonly
                regarded as required of an investment security is present and
                although not distinctly or predominantly speculative, there is
                specific risk.
    
 
   
DESCRIPTION OF STANDARD AND POOR'S MUNICIPAL NOTE RATINGS:
    
 
   
Until June 29, 1984, S&P used the same rating symbols for notes and bonds. After
June 29, 1984, for new municipal note issues due in three years or less the
ratings below usually will be assigned. Notes maturing beyond three years will
most likely receive a bond rating of the type recited above.
    
 
   
SP-1  Strong capacity to pay principal and interest. An issue determined to
       possess a very strong capacity to pay debt service is 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.
    
 
   
COMMERCIAL PAPER RATINGS
    
 
   
DESCRIPTION OF STANDARD & POOR'S CORPORATION'S THREE HIGHEST COMMERCIAL PAPER
RATINGS:
    
 
   
Commercial paper rated "A" by Standard & Poor's Corporation has the following
characteristics: Liquidity ratios are adequate to meet cash requirements.
Long-term senior debt is generally rated "A" or better. The issuer has access to
at least two additional channels of borrowing. Basic earnings and cash flow have
an upward trend with allowance made for unusual circumstances. Typically, the
issuer's industry is well established and the issuer has a strong position
within
    
 
                                      A-4
<PAGE>
   
the industry. The reliability and quality of management are unquestioned.
Relative strength or weakness of the above factors determine whether the
issuer's commercial paper is rated as follows:
    
 
   
A-1   This designation indicates that the degree of safety regarding timely
       payment is strong. Those issues determined to possess extremely strong
       safety characteristics are denoted with a plus sign (+) designation.
    
 
   
A-2   Capacity for timely payment on issues with this designation is
       satisfactory. However, the relative degree of safety is not as high as
       for issues designated 'A-1'.
    
 
   
DESCRIPTION OF MOODY'S INVESTORS SERVICE, INC.'S THREE HIGHEST COMMERCIAL PAPER
RATINGS:
    
 
   
Among the factors considered by Moody's Investors Service, Inc. is assigning
commercial paper ratings are the following: (1) evaluation of the management of
the issuer; (2) economic evaluation of the issuer's industry or industries and
an appraisal of the risks which may be inherent in certain areas; (3) evaluation
of the issuer's products in relation to competition and customer acceptance; (4)
liquidity; (5) amount and quality of long-term debt; (6) trend of earnings over
a period of ten years; (7) financial strength of a parent company and the
relationships which exist with the issuer; and (8) recognition of the management
of obligations which may be present or may arise as a result of public interest
questions and proportions to meet such obligations. Relative differences in
strength and weakness in respect to these criteria would establish a rating in
one of three classifications; "P-1," "P-2" or "P-3."
    
 
   
DESCRIPTION OF FITCH INVESTORS SERVICE COMMERCIAL PAPER, MEDIUM-TERM NOTES, AND
MUNICIPAL AND INVESTMENT NOTES.
    
 
   
F-1+  Exceptionally Strong Credit Quality. Issues assigned this rating are
       regarded as having the strongest degree of assurance for timely payment.
    
 
   
F-1   Very Strong Credit Quality. Issues assigned this rating reflect an
       assurance of timely payment only slightly less in degree than issues
       rated "F-1+."
    
 
   
F-2   Good Credit Quality. Issues assigned this rating have a satisfactory
       degree of assurance for timely payment, but the margin of safety is not
       as great as for issues assigned "F-1+" and "F-1" ratings.
    
 
                                      A-5
<PAGE>
   
F-3   Fair Credit Quality. Issues assigned this rating have characteristics
       suggesting that the degree of assurance for timely payment is adequate,
       however, near-term adverse changes could cause these securities to be
       rated below investment grade.
    
 
   
F-5   Weak Credit Quality. Issues assigned this rating have characteristics
       suggesting a minimal degree of assurance for timely payment and are
       vulnerable to near-term adverse changes in financial and economic
       conditions.
    
 
   
DESCRIPTION OF DUFF & PHELP'S TWO HIGHEST COMMERCIAL RATINGS:
    
 
   
Duff & Phelp's commercial paper ratings place emphasis on liquidity, considering
not only cash from operations, but access to alternative sources of funds,
including trade credit, bank lines and capital markets. Relative differences in
strength and weakness is rated by Duff & Phelp's as Duff-1 or Duff-2; Duff-1
being the highest commercial paper rating and Duff-2 being the second highest
rating.
    
 
   
DESCRIPTION OF THOMSON BANKWATCH, INC.'S TWO HIGHEST COMMERCIAL RATINGS:
    
 
   
Thomson Bankwatch, Inc.'s ratings of United States commercial banks, thrifts,
and non-bank banks, non-United States banks, and broker-dealers are based upon
among other things, five years's financial information and the issuer's most
recent regulatory filings. Relative differences in strength and weakness are
rated by Thomson Bankwatch, Inc.
    
 
   
TBW-1 The highest category; indicates a very high likelihood that principal and
       interest will be paid on a timely basis.
    
 
   
TBW-2 The second-highest category; while the degree of safety regarding timely
       repayment of principal and interest is strong, the relative degree of
       safety is not as high as for issues rated TBW-1.

RISK/RETURN SUMMARY                                    SM&R GOVERNMENT BOND FUND
    
- -------------------------------------------------------------------
 
   
GOVERNMENT BOND FUND'S INVESTMENT OBJECTIVE
                   To provide as high a level of current income,
                   liquidity, and safety of principal as is consistent with
                   prudent investment risks through investment in a portfolio
                   consisting primarily of securities issued or guaranteed by
                   the U.S. Government, its agencies, or instrumentalities.
    
 
   
GOVERNMENT BOND FUND'S PRINCIPAL INVESTMENT STRATEGIES
                   The Government Bond Fund normally invests at
                   least 65% of its assets in securities issued or guaranteed by
                   the U.S. Government, its agencies, or instrumentalities.
                   These may include Treasuries and mortgage-backed securities,
                   such as Ginnie Maes, Freddie Macs, and Fannie Maes. This fund
                   may also invest assets in collateralized mortgage
                   obligations.
    
 
   
                   The Government Bond Fund may invest in zero coupon bonds,
                   which are U.S. Government obligations. The fund may also
                   invest in commercial paper, certificates of deposit,
                   corporate debt securities rated "A" or higher, and repurchase
                   agreements.
    
 
   
PRINCIPAL RISKS OF INVESTING IN THE GOVERNMENT BOND FUND
                   You could lose money on your investment in the
                   Government Bond Fund, or it could underperform other
                   investments, if any of the following occurs:
    
   
                   - interest rates rise (thus causing a decline in the market
                     value of debt securities)
    
   
                   - the worldwide demand for U.S. government securities falls
    
   
                   - interest rates fall enough to prompt an unexpected number
                     of people to refinance (or prepay) their mortgages
    
   
                   - interest rates rise enough to cause fewer people than
                     expected to repay their mortgages early
    
   
                   - if any bonds the fund owns are downgraded in credit rating
                     or go into default

WHO MAY WANT TO INVEST IN THE GOVERNMENT BOND FUND
                   The Government Bond Fund may be
                   appropriate if you:
    
   
                   - are seeking a regular stream of income to meet current
                     needs

                   The Government Bond Fund may NOT be appropriate if you:
    
   
                   - are investing for maximum return over a long time horizon

RISK/RETURN SUMMARY                                           SM&R TAX FREE FUND
    
- -------------------------------------------------------------------
 
   
TAX FREE FUND'S INVESTMENT OBJECTIVE
                   To provide as high a level of interest income
                   largely exempt from federal income taxes as is consistent
                   with preservation of capital through investment of at least
                   80% of its net assets in tax-exempt securities during normal
                   market conditions.
    
 
   
TAX FREE FUND'S PRINCIPAL INVESTMENT STRATEGIES
                   The Tax Free Fund invests primarily in tax-
                   exempt securities. During normal market conditions, this fund
                   invests at least 80% of its assets in municipal securities
                   that pay interest exempt from federal income taxes. This fund
                   may not invest more than 20% of its assets in UNRATED
                   municipal securities. These securities may be less liquid
                   than comparably rated municipal securities and involve
                   somewhat greater risk. This fund may also invest up to 20% of
                   its assets in Government guaranteed taxable bonds, highly
                   rated corporate bonds, or commercial paper.
    
 
   
PRINCIPAL RISKS OF INVESTING IN THE TAX FREE FUND
                   You could lose money on your investment in the
                   Tax Free Fund, or it could underperform other investments, if
                   any of the following occurs:
    
   
                   - interest rates rise (thus causing a decline in the market
                     value of debt securities)
    
   
                   - if any bonds the fund owns are downgraded in credit rating
                     or go into default
    
   
                   - certain securities become harder to value or to sell at a
                     fair price
    
 
   
                   ALSO, SOME OF YOUR DIVIDEND INCOME MAY BE TAXABLE.

                   The Tax Free Fund may be appropriate if you:
   
                   - are willing to sacrifice some investment return for income
                     exempt from federal income tax and, under certain
                     conditions, exempt from state and local taxes
    
   
                   - are in a high tax bracket (28% and up)

- -------------------------------------------------------------------
 
   
PRIMARY FUND'S INVESTMENT OBJECTIVE
                   To seek maximum current income consistent
                   with capital preservation and liquidity through investment
                   primarily in commercial paper.
    
 
   
PRIMARY FUND'S PRINCIPAL INVESTMENT STRATEGIES
                   The Primary Fund invests primarily in
                   commercial paper. Commercial paper is short-term unsecured
                   promissory notes issued by corporations. This fund will only
                   invest in commercial paper rated in one of the two highest
                   rating categories.
    
 
   
                   The Primary Fund may also invest in:
    
   
                   - U.S. Government obligations;
    
   
                   - corporate debt obligations maturing in five years or less
                     and rated "A" or higher;
    
   
                   - certificates of deposit; and
    
   
                   - repurchase agreements.
    
 
   
PRINCIPAL RISKS OF INVESTING IN THE PRIMARY FUND
                   You could lose money on your investment in the
                   Primary Fund, or it could underperform other investments, if
                   any of the following occurs:
    
   
                   - interest rates rise (thus causing a decline in the market
                     value of debt securities)
    
   
                   - if any of the fund's investments are downgraded in credit
                     rating or go into default
    
 
   
                   By limiting its investments as described above, the Primary
                   Fund may not achieve as high a level of current income as a
                   fund investing in lower-rated securities or longer-term
                   securities.

MONEY MARKET FUND'S INVESTMENT OBJECTIVE
                   To seek the highest current income consistent
                   with the preservation of capital and maintenance of
                   liquidity.
    
 
   
MONEY MARKET FUND'S PRINCIPAL INVESTMENT STRATEGIES
                   The Money Market Fund seeks to achieve its
                   objective by investing in high-quality short-term money
                   market instruments, including: U.S. Government obligations,
                   certificates of deposit, banker's acceptances, commercial
                   paper, collateralized mortgage obligations, and corporate
                   bonds and notes. This fund limits its investments to those
                   short-term securities that it determines present minimal
                   credit risk and meet certain rating requirements (in the two
                   highest short-term rating categories).
    
 
   
PRINCIPAL RISKS OF INVESTING IN THE MONEY MARKET FUND
                   The Money Market Fund is subject to the
                   following risks:
    
   
                   - that interest rates may rise (thus causing a decline in the
                     market value of debt securities)
    
   
                   - that the fund's investments may be downgraded in credit
                     rating or go into default
    
 
   
                   However, the risks of investment in the Money Market Fund may
                   be expected to be less than for other mutual funds. By
                   limiting its investments as described above, this fund may
                   not achieve as high a level of current income as a fund
                   investing in lower-rated securities. Also, there is a remote
                   possibility that this fund's share value could fall below
                   $1.00, which could reduce the value of your account.

WHO MAY WANT TO INVEST IN THE MONEY MARKET FUND
                   The Money Market Fund may be appropriate if
                   you:
    
   
                   - require stability of principal
    
   
                   - are seeking a mutual fund for the cash portion of an asset
                     allocation program
    
   
                   - need to "park" your money temporarily
    
   
                   - consider yourself a saver rather than an investor
    
   
                   - are investing emergency reserves
    
 
   
                   The Money Market Fund may NOT be appropriate if you:
    
   
                   - want federal deposit insurance
    
   
                   - are seeking an investment that is likely to outpace
                     inflation
    
   
                   - are investing for retirement or other goals that are many
                     years in the future
    
   
                   - are investing for growth or maximum current income
    
   
AN INVESTMENT IN THE MONEY MARKET FUND IS NOT INSURED OR GUARANTEED BY THE
FEDERAL DEPOSIT INSURANCE CORPORATION OR ANY OTHER GOVERNMENT AGENCY. ALTHOUGH
THE MONEY MARKET FUND SEEKS TO PRESERVE THE VALUE OF YOUR INVESTMENT AT $1.00
PER SHARE, IT IS POSSIBLE TO LOSE MONEY BY INVESTING IN THE MONEY MARKET FUND.

RISK/RETURN SUMMARY
    
- -------------------------------------------------------------------
 
   
TYPES OF INVESTMENT RISK
    
 
   
As indicated above, each of the four funds may be subject to certain of the
following types of risks:
    
 
   
CREDIT RISK. The risk that the issuer of a security, or a party to a contract,
will default or otherwise not honor a financial obligation.
    
 
   
INTEREST RATE RISK. The risk of declines in market value of an income-bearing
investment due to changes in prevailing interest rates. With fixed-rate
securities, a rise in interest rates typically causes a decline in market
values, while a fall in interest rates typically causes an increase in market
values.
    
 
   
LIQUIDITY RISK. The risk that certain securities or other investments may be
difficult or impossible to sell at the time the fund would like to sell them or
at the price the fund values them. The fund may have to sell at a lower price,
sell other securities instead, or forego an investment opportunity, any of which
could have a negative effect on fund management or performance.
    
 
   
MANAGEMENT RISK. The risk that a strategy used by a fund's management may fail
to produce the intended result. This risk is common to all mutual funds.
    
 
   
MARKET RISK. The risk that the market value of a security may move up and down,
sometimes rapidly and unpredictably. The fluctuations may cause a security to be
worth less than the price originally paid for it, or less than it was worth at
an earlier time. Market risk may affect a single issuer, industry, sector of the
economy, or the market as a whole. This risk is common to all stocks and bonds
and the mutual funds that invest in them.
    
 
   
PREPAYMENT AND EXTENSION RISK. PREPAYMENT RISK is the risk that an unexpected
fall in prevailing interest rates will shorten the life of an outstanding
mortgage-backed security by increasing the actual or expected number of mortgage
prepayments, thereby reducing the security's value. EXTENSION RISK is the risk
that an unexpected rise in prevailing interest rates will extend the life of an
outstanding mortgage-backed security by reducing the actual or expected number
of mortgage prepayments, thereby reducing the security's value.

RISK/RETURN SUMMARY
    
- ------------------------------------------------
 
   
BAR CHART AND PERFORMANCE TABLE
    
 
   
The bar charts and performance tables shown below provide some indication of the
risks of investing in the funds and the variability of returns by showing each
fund's performance for each year since inception and by showing how each fund's
average annual returns for certain periods compare to those of a broad-based
securities market index. Because the Money Market Fund was not in operation
during these periods, it is not included in the bar chart or the performance
table.
    
 
   
The returns shown are based on an investment in the funds prior to the creation
of multiple classes of shares, but do not reflect any sales loads that would be
imposed on the purchase or sale of any shares. If multiple classes of shares of
the Government Bond and Tax Free Funds had been in existence, the financial
performance of Class J shares would have been lower than depicted because of the
imposition of distribution and/or service (12b-1) fees.
    
 
   
Past performance is not necessarily an indication of how the funds will perform
in the future.

    manager, Securities Management and Research, Inc. ("SM&R"). Pursuant to the
    Administrative Service Agreement, SM&R will pay (or reimburse) each fund for
    regular operating expenses in excess of 1.25% (0.35% for the Money Market
    Fund) per year of such fund's average daily net assets. Regular operating
    expenses include the advisory fee and administrative fee, but do not include
    any 12b-1 fee or class-specific expenses.
    
 
   
    SM&R may also waive fees or assume expenses on a voluntary basis. During the
    fiscal year ended August 31, 1998, SM&R voluntarily waived fees of [___]%,
    [___]%, and [___]% for the Government Bond Fund, Primary Fund, and Tax Free
    Fund, respectively, and reimbursed expenses of [___]% for the Tax Free Fund.
    SM&R intends to continue to voluntarily waive the advisory fee for the Tax
    Free Fund. SM&R also intends to reimburse regular operating expenses that
    exceed average daily net assets as follows: 0.80% for the Primary Fund and
    1.00% for the Government Bond Fund. SM&R may discontinue or reduce any such
    waiver or reimbursement of expenses at any time without notice.
    
 
   
    The following table shows fees and expenses for the Government Bond,

RISK/RETURN SUMMARY
    
- ------------------------------------------------
 
   
EXAMPLES OF EXPENSES
    
 
   
These examples are intended to help you compare the cost of investing in the
funds with the cost of investing in other mutual funds. These examples assume
that you invest $10,000 in each fund and applicable class thereof for the time
periods indicated, based on expenses before fee waivers and expense
reimbursements. These examples also assume that your investment has a 5% return
each year and that the funds' operating expenses remain the same. YOUR ACTUAL
COSTS MAY BE HIGHER OR LOWER THAN SHOWN.
    
 
   
You would pay the following expenses, based on these assumptions, if you
actually redeem all of your shares at the end of the period shown:

SHARES OF THE FUNDS
    
- -------------------------------------------------------------------
 
   
SM&R Investments, Inc., formerly known as SM&R Capital Funds, Inc. (the
"Company" or "we") offers four separate investment portfolios. This prospectus
offers Class J shares of the Government Bond and Tax Free Funds and shares of
the Money Market and Primary Funds through financial intermediaries that have
distribution agreements with SM&R. These financial intermediaries may include
broker-dealers, investment advisers, and mutual fund "marketplaces", and may
charge you separately for their services.
    
 
   
Class J shares of the Government Bond and Tax Free Funds and shares of the Money
Market and Primary Funds are offered at their respective net asset values,
without the imposition of any sales charge on their purchase or redemption. As a
result, 100% of your purchase is immediately invested. Class J shares of the
Government Bond and Tax Free Funds, however, have higher ongoing expenses
because of the imposition of a distribution ("12b-1") fee.
    
 
   
The Government Bond and Tax Free Funds also offer other classes of shares
through separate prospectuses: (1) Class A "front-end load" shares; (2) Class B
"back-end load" shares; (3) Class C "level load" shares; (4) Class T shares sold
only to investors that became shareholders of the Company prior to December 31,
1998 and certain designated persons; and (5) Class Y "institutional" shares.
Class A, B, C, T, and Y shares are subject to different sales charges and other
expenses and, accordingly, may have expense ratios and performance that differs
from those of Class J shares. You are encouraged to consider all of the
Company's class alternatives and choose the one that fits your individual
circumstances at the lowest level of fees. FOR MORE INFORMATION ON THE OTHER
CLASSES OF SHARES OR TO REQUEST A PROSPECTUS FOR ANOTHER CLASS, INVESTORS MAY
CONTACT INVESTOR SERVICES AT (800) 231-4639.
    
 
   
DISTRIBUTION AND SHAREHOLDER SERVICE (12b-1) FEE
    
 
   
Class J shares of the Government Bond and Tax Free Funds pay SM&R, the principal
underwriter, a distribution (12b-1) fee of 0.75%. This fee is computed as an
annual percentage of the average daily net assets of the class. BECAUSE
DISTRIBUTION (12b-1) FEES ARE PAID OUT OF FUND ASSETS ON AN ONGOING BASIS, THE
FEES MAY, OVER TIME, INCREASE THE COST OF AN INVESTMENT IN A FUND AND COST
INVESTORS MORE THAN OTHER TYPES OF SALES LOADS.
    
 
                                       17
<PAGE>
   
The distribution fee is for services that are primarily intended to result in or
are primarily attributable to the sale of the classes. This fee compensates
SM&R, or enables SM&R to compensate other persons (including distributors of the
shares), for providing such services.
    
 
   
INVESTMENT OBJECTIVES AND POLICIES
    
- -------------------------------------------------------------------
 
   
Each fund pursues its own investment objective through various investment
policies and techniques. ONLY THE PRINCIPAL INVESTMENT STRATEGIES OF EACH FUND
AND THE PRINCIPAL TYPES OF SECURITIES EACH FUND PLANS TO PURCHASE ARE DESCRIBED
BELOW. These policies and techniques are not fundamental and may be changed by
the Board of Directors without shareholder approval.
    
 
   
Because of the market risks inherent in any investment, the funds may not
achieve their investment objectives. In addition, effective management of each
fund is subject to general economic conditions and to the ability and investment
techniques of management. The net asset value of each fund's shares will vary
and the redemption value of shares may be either higher or lower than the
shareholder's cost. Since each fund has a different investment objective, each
will have different investment results and incur different market, financial,
and other risks.
    
 
   
GOVERNMENT BOND FUND
(FORMERLY NAMED AMERICAN NATIONAL GOVERNMENT INCOME FUND SERIES)
    
 
   
The Government Bond Fund seeks to achieve its objective through investment of
65% or more of its total assets in securities issued or guaranteed by the U.S.
Government, its agencies or instrumentalities ("U.S. Government Obligations")
which include, but are not limited to, U.S. Treasury Bonds, Notes and Bills and
securities issued by instrumentalities of the U.S. Government.
    
 
   
U.S. GOVERNMENT OBLIGATIONS--There are two broad categories of U.S. Government
Obligations:
    
 
   
(1) direct obligations of the U.S. Treasury, and
    
 
   
(2) obligations issued or guaranteed by agencies or instrumentalities of the
    U.S. Government.
    
 
                                       18
<PAGE>
   
Some obligations issued or guaranteed by agencies or instrumentalities of the
U.S. Government are backed by the full faith and credit of the United States
(such as Government National Mortgage Association Certificates); others, by the
agency or instrumentality with limited rights of the issuer to borrow from the
U.S. Treasury (such as Federal National Mortgage Association Bonds); and others,
only by the credit of the issuer. No assurance can be given that the U.S.
Government would lend money to or otherwise provide financial support to U.S.
Government sponsored instrumentalities; it is not obligated by law to do so.
    
 
   
MORTGAGE-BACKED SECURITIES--We anticipate that a substantial portion of the
Government Bond Fund's portfolio will consist of mortgage-backed securities
issued or guaranteed by the U.S. Government, its agencies, or instrumentalities.
These securities represent part ownership of pools of mortgage loans secured by
real property, such as certificates issued by the Government National Mortgage
Association ("GNMA" or "Ginnie Mae"), the Federal National Mortgage Association
("FNMA" or "Fannie Mae"), and the Federal Home Loan Mortgage Corporation
("FHLMC" or "Freddie Mac"). Mortgage-backed securities also include mortgage
pass-through certificates representing participation interests in pools of
mortgage loans originated by the U.S. Government and guaranteed by U.S.
Government agencies such as GNMA, FNMA, or FHLMC. Such certificates, which are
ownership interests in the underlying mortgage loans, differ from conventional
debt securities which provide for periodic payment of interest in fixed amounts
and principal payments at maturity or on specified dates. With pass-through
certificates, both principal and interest payments, including prepayments, are
passed through to the holder of the certificate and provide for monthly payments
of interest and principal. GNMA, a federal agency, issues pass-through
certificates that are guaranteed as to timely payment of principal and interest.
FNMA, a federally chartered and privately owned corporation, issues mortgage
pass-through securities and guarantees them as to timely payment of principal
and interest. FHLMC, a corporate instrumentality of the United States, issues
participation certificates that represent an interest in mortgages from FHLMC's
portfolio. FHLMC guarantees the timely payment of interest and the ultimate
collection of principal. FNMA and FHLMC are not backed by the full faith and
credit of the United States, although FNMA and FHLMC are authorized to borrow
from the U.S. Treasury to meet their obligations. Those mentioned are but a few
of the mortgage-
    
 
                                       19
<PAGE>
   
backed securities currently available. The Government Bond Fund will not
purchase interest-only or principal-only mortgage-backed securities.
    
 
   
The yield characteristics of mortgage-backed securities differ from traditional
debt securities. Among the major differences are that interest and principal
payments are made more frequently, usually monthly, and that principal may be
prepaid at any time because the underlying mortgage loans generally may be
prepaid at any time. The average mortgage in a pool may be expected to be repaid
within about twelve (12) years. If mortgage interest rates decrease, the value
of the Government Bond Fund's securities will generally increase. However, we
anticipate that the average life of the mortgages in the pool will decrease as
borrowers refinance and prepay mortgages to take advantage of lower interest
rates. The Government Bond Fund invests the proceeds from such prepayments at
the then prevailing lower interest rates. On the other hand, if interest rates
increase, the value of the Fund's securities generally will decrease while it is
anticipated that borrowers will not refinance and, therefore, the average life
of the mortgages in the pool will be longer. In addition, if the Government Bond
Fund purchases such a security at a premium, a prepayment rate faster than
expected will reduce yield to maturity, while a prepayment rate slower than
expected will have the opposite effect of increasing yield to maturity.
Conversely, if the Government Bond Fund purchases these securities at a
discount, faster than expected prepayments will increase yield to maturity,
while slower than expected prepayments will reduce yield to maturity.
    
 
   
COLLATERALIZED MORTGAGE OBLIGATIONS--The Government Bond Fund may invest a
portion of its assets in collateralized mortgage obligations or "CMOs," which
are debt obligations collateralized by a portfolio or pool of mortgages,
mortgage-backed securities, or U.S. Government securities. Collateralized
obligations in which the Government Bond Fund may invest are issued or
guaranteed by a U.S. Government agency or instrumentality, such as the FHLMC. A
variety of types of collateralized obligations are currently available and
others may become available in the future. One should keep in mind that during
periods of rapid interest rate fluctuation, the price of a security, such as a
CMO, could either increase or decrease based on inherent interest rate risk.
Additionally, the risk of maturities shortening or lengthening in conjunction
with interest rate movement, could magnify the overall effect of the price
fluctuation.
    
 
                                       20
<PAGE>
   
A CMO is often issued in multiple classes with varying maturities and interest
rates. As a result the investor may obtain greater predictability of maturity
than with direct investments in mortgage-backed securities. Thus, classes with
shorter maturities may have lower volatility and lower yield while those with
longer maturities may have higher volatility and higher yields. This provides
the investor with greater control over the characteristics of the investment in
a changing interest rate environment. A more complete description of CMOs is
contained in the Statement of Additional Information.
    
 
   
The Government Bond Fund may also invest in parallel pay CMOs and Planned
Amortization Class CMOs ("PAC Bonds"). Parallel pay CMOs are structured to
provide payments of principal on each payment date to more than one class. PAC
Bonds generally require payments of a specified amount of principal on each
payment date. PAC Bonds are always parallel pay CMOs with the required principal
payment on such securities having the highest priority after interest has been
paid to all classes.
    
 
   
The Government Bond Fund may also invest in securities issued by private issuers
that represent an interest in or are secured by mortgage-backed securities
issued or guaranteed by the U.S. government or one of its agencies or
instrumentalities. In addition, the fund may invest in securities issued by
private issuers that represent an interest in or are secured by mortgage loans
or mortgage-backed securities without a government guarantee but usually have
some form of private credit enhancement.
    
 
   
ZERO COUPON BONDS--The Government Bond Fund may invest in zero coupon bonds,
which are debt obligations issued or purchased at a significant discount from
face value. The Government Bond Fund will only purchase zero coupon bonds which
are U.S. Government Obligations. The discount approximates the total amount of
interest the bonds will accrue and compound over the period until maturity or
the first interest payment date at a rate of interest reflecting the market rate
of the security at the time of issuance. Zero coupon bonds do not entitle the
holder to any periodic payments of interest prior to maturity. Its value as an
investment consists of the difference between its face value at the time of
maturity and the price for which it was acquired which is generally an amount
significantly less than face value (sometimes referred to as a "deep discount"
price). Zero coupon bonds require a higher rate of return to attract investors
who
    
 
                                       21
<PAGE>
   
are willing to defer receipt of cash. Accordingly, although not providing
current income, SM&R believes that zero coupon bonds can be effectively used to
lock in a higher rate of return in a declining interest environment. Such
investments may experience greater volatility in market value than debt
obligations which make regular payments of interest. The Fund will accrue income
on such investments for tax and accounting purposes, as required, which is
distributable to shareholders and which, because no cash is received at the time
of accrual, may require the liquidation of other portfolio securities to satisfy
the Fund's distribution obligations.
    
 
   
TAX FREE FUND (FORMERLY NAMED AMERICAN NATIONAL TAX FREE FUND SERIES)
    
 
   
The Tax Free Fund, as a matter of fundamental policy, seeks to achieve its
objective by investing at least 80% of the value of its net assets in municipal
securities the interest on which is exempt from federal income taxes.
    
 
   
The Tax Free Fund has no restrictions on the maturity of municipal securities in
which it may invest. Accordingly, it will seek to invest in municipal securities
of such maturities which, in the judgement of SM&R, the adviser, will provide a
high level of current income consistent with prudent investment, with
consideration given to market conditions.
    
 
   
The Tax Free Fund will invest, without percentage limitations, in municipal
securities having at the time of purchase one of the four highest municipal
ratings by Moody's Investor Service, Inc. ("Moody's"), Standard & Poor's
Corporation ("S&P"), or Fitch Investors Service (E.G., MIG 4 or higher by
Moody's) or in securities which are not rated, provided that, in the opinion of
SM&R, such securities are comparable in quality to those within the four highest
ratings. The rating agencies consider that bonds rated in the fourth highest
category may have some speculative characteristics and that changes in economic
conditions or other circumstances are more likely to lead to a weakened capacity
to make principal and interest payments on those bonds than is the case with
higher grade bonds. SM&R will only purchase bonds rated in such fourth category
if it believes that the purchase of such bonds is consistent with the Tax Free
Fund's investment objective. In the event the rating of an issue held by the Tax
Free Fund is changed by the rating service, such change will be considered by
the Tax Free Fund in its evaluation of
    
 
                                       22
<PAGE>
   
the overall investment merits of that security but such change will not
necessarily result in an automatic sale of the security. Any security held which
is subsequently downgraded below BBB by S&P or Baa by Moody's will be sold as
soon as it is advantageous to do so after the downgrade. A description of the
ratings may be found in the Appendix to this Prospectus.
    
 
   
Purchasing unrated municipal securities, which may be less liquid than
comparably rated municipal securities, involves somewhat greater risk and
consequently the Tax Free Fund may not invest more than 20% of its net assets in
unrated municipal securities. To attempt to minimize the risk of such
investments, SM&R will, prior to acquiring unrated securities, consider the
terms of the offering and various other factors to determine the issuer's
comparative credit rating and whether the securities are consistent with the Tax
Free Fund's investment objective and policies.
    
 
   
During normal market conditions, the Tax Free Fund will have at least 80% of its
net assets invested in municipal securities the income of which is fully exempt
from federal income taxation. Furthermore, under normal market conditions up to
20% of the Tax Free Fund's net assets, and as a temporary defensive measure
during abnormal market conditions, up to 50% of its net assets may be invested
in the following types of taxable fixed income obligations:
    
 
   
(1) obligations issued or guaranteed by the U.S. government, its agencies,
    instrumentalities or authorities (See "Government Bond Fund" above for an
    explanation of U.S. government obligations);
    
 
   
(2) corporate debt securities which at the date of the investment are rated A or
    higher by Moody's or by S&P;
    
 
   
(3) commercial paper which at the date of the investment is rated in one of the
    two top categories by Moody's or by S&P or if not rated, is issued by a
    company which at the date of the investment has an outstanding debt issue
    rated A or higher by Moody's or A or higher by S&P;
    
 
   
(4) certificates of deposit issued by U.S. banks which at the date of the
    investment have capital surplus and undivided profits of $1 billion as of
    the date of their most recently published financial statements; and
    
 
                                       23
<PAGE>
   
(5) repurchase agreements secured by U.S. government securities, provided that
    no more than 15% of the Fund's net assets will be invested in illiquid
    securities including repurchase agreements with maturities in excess of
    seven days.
    
 
   
To the extent income dividends include income from taxable sources, a portion of
a shareholder's dividend income may be taxable. (See "Dividends, Distributions,
and Taxes"). In addition, Congress could enact tax legislation such as a flat
tax rate that would make tax-free bonds less desirable to investors seeking ways
to reduce taxable income. If that were to occur, it could cause the value of the
securities to drop.
    
 
   
The Tax Free Fund's ability to achieve its objective depends partially on the
prompt payment by issuers of the interest on and principal of the municipal
securities held. A moratorium, default, or other non-payment of interest or
principal when due could, in addition to affecting the market value and
liquidity of the particular security, affect the market value and liquidity of
other municipal securities. Additionally, the market for municipal securities is
often thin and can be temporarily affected by large purchases and sales. As a
result, the Tax Free Fund will attempt to minimize risk by diversifying its
investments by investing no more than 5% of its net assets in the securities of
any one issuer (this limitation does not apply to investments issued or
guaranteed by the U.S. Government or its instrumentalities) and by investing no
more than 25% of its net assets in municipal securities issued in any one state
or territory. Each political subdivision, agency, instrumentality, and each
multi-state agency of which a state is a member will be regarded as a separate
issuer for the purpose of determining diversification.
    
 
   
MUNICIPAL SECURITIES--The term "municipal securities," as used in this
Prospectus means obligations issued by or on behalf of states, territories, and
possessions of the U.S. and the District of Columbia and their political
subdivisions, agencies, and instrumentalities, the interest on which is exempt
from federal income tax. An opinion as to the tax-exempt status of a municipal
security generally is rendered to the issuer by the issuer's counsel at the time
of issuance of the security. Neither the funds nor SM&R will review the
proceedings relating to the issuance of municipal obligations or the basis for
opinions of counsel.
    
 
                                       24
<PAGE>
   
Municipal securities are used to raise money for various public purposes such as
constructing public facilities and making loans to public institutions. Certain
types of municipal bonds are issued to obtain funding for privately operated
facilities. Further information on the maturity and funding classifications of
municipal securities is included in the Statement of Additional Information.
    
 
   
Yields on municipal securities vary, depending on a variety of factors,
including the general condition of the financial markets and of the municipal
securities market, the size of a particular offering, the maturity of the
obligation and the credit rating of the issuer. Like other interest-bearing
securities, the value of municipal securities changes as interest rates
fluctuate. For example, if interest rates increase from the time a security is
purchased, the security's value and sales price generally will be less than its
purchase cost. Conversely, if interest rates decline from the time a security is
purchased, the security's value and sales price may be greater than its purchase
cost. Generally, municipal securities of longer maturities produce higher
current yields than municipal securities with shorter maturities but are subject
to greater price fluctuation due to changes in interest rates, tax laws and
other general market factors. Lower-rated municipal securities generally produce
a higher yield with shorter maturities than higher-rated municipal securities
due to the perception of a greater degree of risk as to the ability of the
issuer to pay principal and interest.
    
 
   
The Tax Free Fund may purchase municipal bonds for which the payments of
principal and interest are secured by an escrow account of securities backed by
the full faith and credit of the U.S. government ("defeased") and municipal
securities whose principal and interest payments are insured by a commercial
insurance company as long as the underlying credit is investment grade (BBB or
better by S&P and Fitch and Baa or better by Moody's) ("insured"). The Tax Free
Fund may also purchase unrated securities of issuers which SM&R believes would
have been rated BBB or Baa had the issuer requested a rating from S&P, Fitch or
Moody's. Such implied investment grade rating will be determined by SM&R upon
its performance of a credit analysis of the issue and the issuer. Such credit
analysis may consist of a review of such items as the issuer's debt
characteristics, financial information, structure of the issue, liquidity of the
issue, quality of the issuer, current economic climate, financial adviser, and
underwriter. Insured and defeased bonds are
    
 
                                       25
<PAGE>
   
further described in the Statement of Additional Information. In general, these
types of municipal securities will not be treated as an obligation of the
original municipality for purposes of determining industry concentration.
    
 
   
PRIMARY FUND (FORMERLY NAMED AMERICAN NATIONAL PRIMARY FUND SERIES)
    
 
   
Commercial paper is short-term unsecured promissory notes issued by corporations
to finance short-term credit needs. Commercial paper is usually sold on a
discount basis and has a maturity at the time of issuance not exceeding nine
months. The Primary Fund will invest only in commercial paper which, at the date
of such investment, is rated in one of the two top categories by one or more of
the nationally recognized statistical rating organizations ("NRSROs") (See the
"Appendix" hereto for information about such ratings and such rating
organizations).
    
 
   
The Primary Fund, consistent with its investment objective, will attempt to
maximize yield by trying to take advantage of changing conditions and trends. It
may also attempt to take advantage of what are believed to be disparities in
yield relationships between different instruments. This procedure may increase
or decrease the portfolio yield depending upon the Primary Fund's ability to
correctly time and execute such transactions. Although the Primary Fund's assets
will be invested in securities with short maturities, the Primary Fund will
manage its portfolio as described above. (See "Portfolio Transactions and
Brokerage Allocation" in the Statement of Additional Information.)
    
 
   
OTHER INVESTMENTS--The Primary Fund may invest in (i) U.S. Government
Obligations (See the "Government Bond Fund" above for an explanation of U.S.
Government Obligations); (ii) other corporate obligations, such as bonds,
debentures or notes maturing in five (5) years or less at the time of purchase
which at the date of the investment are rated "A" or higher by an NRSRO; and
(iii) negotiable certificates of deposit of banks (including U.S. dollar
denominated obligations of foreign branches of U.S. banks and U.S. branches of
foreign banks and savings and loan associations and banker's acceptances of U.S.
banks which banks and savings and loan associations have total assets at the
date of investment (as of the date of their most recent published financial
statements) of at least $1 billion (See "INVESTMENT OBJECTIVES AND
POLICIES--Certificates of
    
 
                                       26
<PAGE>
   
Deposit" in the Statement of Additional Information for a description of the
securities) and (iv) repurchase agreements with respect to any type of
instrument in which the Primary Fund is authorized to invest even though the
underlying instrument may mature in more than two (2) years.
    
 
   
MONEY MARKET FUND
    
 
   
The Money Market Fund seeks to achieve its objective by investing in short-term
money market instruments determined to be of high quality by SM&R pursuant to
guidelines established by the Company's Board of Directors. The Money Market
Fund may invest in the following types of high quality debt obligations:
    
 
   
(1) U.S. GOVERNMENT OBLIGATIONS. U.S. Government Obligations consist of
marketable securities issued or guaranteed as to both principal and interest by
the United States Government or by its agencies and instrumentalities. (See
"Government Bond Fund" above for an explanation of U.S. Government Obligations).
    
 
   
(2) CERTIFICATES OF DEPOSIT. Certificates of deposit are negotiable certificates
issued against funds deposited in a commercial bank for a definite period of
time and earning a specified return. The Money Market Fund will invest only in
certificates of deposit of U.S. banks that have total assets in excess of $1
billion at the time of investment.
    
 
   
(3) BANKER'S ACCEPTANCES. Banker's acceptances are short-term instruments issued
by banks, generally for the purpose of financing imports or exports. An
acceptance is a time draft drawn on a bank by the importer or exporter to obtain
a stated amount of funds to pay for specific merchandise. The draft is then
"accepted" and is an irrevocable obligation of the issuing bank.
    
 
   
(4) COMMERCIAL PAPER. As discussed above under "Primary Fund," commercial paper
is short-term unsecured promissory notes issued by corporations to finance
short-term credit needs.
    
 
   
(5) BONDS AND NOTES. The Money Market Fund may invest in corporate bonds or
notes with a remaining maturity of one year or less.
    
 
   
(6) COLLATERALIZED MORTGAGE OBLIGATIONS. As discussed above under "Government
Bond Fund," CMOs are debt obligations collateralized by a portfolio or pool of
mortgages, mortgage-backed securities, or U.S. Government securities.
    
 
                                       27

The Money Market Fund does not currently intend to invest in unrated securities,
securities subject to demand features, floating rate instruments, securities
subject to guarantees, and variable rate instruments.
    
 
   
The Money Market Fund limits its investments to those short-term securities that
the Board determines present minimal credit risk and that are "Eligible
Securities" when acquired by the Fund. As used in this Prospectus, "Eligible
Securities" means securities that are:
    
 
   
(a) rated in one of the two highest short-term rating categories, or
    
 
   
(b) whose issuer has another class of debt obligations rated in one of the two
    highest short-term rating categories.
    
 
   
To rely on a rating assigned to other debt obligations, those obligations must
be of comparable priority and security. All ratings must have been issued by the
requisite NRSROs. Currently, five organizations are NRSROs: Moody's, S&P, Fitch
Investors Service, Inc., Duff and Phelps, Inc., and Thomson BankWatch, Inc. A
discussion of the ratings categories of S&P and Moody's is contained in the
Appendix.
    
 
   
The Money Market Fund generally limits its investments in securities, as
follows:
    
 
   
  - It will not invest in securities issued by any one issuer, other than the
    U.S. Government, its agencies, or instrumentalities, in an amount that
    exceeds 5% of its total assets.
    
 
   
  - It will not invest more than 5% of its total assets in securities relying on
    ratings in the second highest rating category.
    
 
   
  - It will not invest more than 1% of its total assets in securities of any one
    issuer that rely on ratings in the second highest rating category.
    
 
   
(See "Investment Objectives and Policies" in the Statement of Additional
Information for a more detailed explanation of the investment categories.) The
Fund will maintain a dollar-weighted average portfolio maturity of 90 days or
less, and will not invest in any security with a remaining maturity of over 397
days (13 months).
    
 
   
Investments in money market instruments are subject to the ability of the issuer
to make payment at maturity. In addition, the Money Market Fund's performance
will vary depending on changes in short-term interest rates. However, both the
financial and market risks of
    
 
                                       28
<PAGE>
   
investment in the Money Market Fund may be expected to be less than for any
other Fund. By limiting its investments to Eligible Securities, the Money Market
Fund may not achieve as high a level of current income as a fund investing in
lower-rated securities.
    
 
   
RISK FACTORS
    
- -------------------------------------------------------------------
 
   
The following discussion relates to all four funds. The risk/return summary
located at the beginning of this prospectus identifies some specific risks
applicable to each individual fund.
    
 
   
GENERAL. There is no assurance that a fund will achieve its goals. Generally, if
the securities owned by a fund increase in value, the value of the shares of the
fund which you own will increase. Similarly, if the securities owned by a fund
decrease in value, the value of your shares will also go down. In this way, you
participate in any change in the value of the securities owned by a fund.
    
 
   
The risk inherent in investing in any fund is a risk common to any security.
That is, the value of a fund's shares will fluctuate in response to changes in
economic conditions, interest rates and the market's perception of the
underlying portfolio securities held by that fund. Each fund's share value
depends on general economic and securities market conditions, the investment
decisions of its management, and numerous other factors. All of these factors
are inherently uncertain and, in some cases, unforeseeable.
    
 
   
Any of the funds could lose money if the stock markets in general go down or if
the particular debt obligations purchased by a fund go down in value. In
addition, the funds could lose money if prevailing interest rates increase or if
the debt securities purchased by a fund are downgraded or defaulted upon.
    
 
   
DEBT SECURITIES RISKS. Debt securities are subject to change in their values due
to changes in prevailing interest rates. The magnitude of these fluctuations
will often be greater for longer-term debt securities than shorter-term debt
securities. When prevailing interest rates fall, the values of already-issued
debt securities generally rise. Accordingly, if interest rates go down after a
security is purchased, such security might be valued and/or sold at a price
greater than its cost. If interest rates were to drop dramatically, some of the
securities could be called and/or prepaid, requiring reinvesting in securities
at much lower yields.
    
 
                                       29
<PAGE>
   
On the other hand, when prevailing interest rates rise, the values of
already-issued debt securities generally fall. Accordingly, if interest rates
increase after a security is purchased, such security might be valued and/or
sold at a price less than its cost. In such circumstances, the value of existing
bonds decrease because the interest payments from existing bonds are less
attractive than new issues with higher interest rates and investors would lose
money if they liquidate holdings.
    
 
   
The funds could lose money if any bonds they own are downgraded in credit rating
or go into default. A moratorium, default, or other non-payment of interest or
principal when due could, in addition to affecting the market value and
liquidity of the particular security, affect the market value and liquidity of
other securities. A change in credit rating of an issuer can also affect the
bond's value, thus affecting the market value of the funds. However, the funds
invest predominately in investment grade bonds in order to minimize credit risk.
(See "Investment Objectives and Policies" for more information about the ratings
required for investments by each specific fund.) Moreover, substantial
redemptions of fund shares could require a fund to sell portfolio securities at
a time when a sale might not be favorable.
    
 
   
U.S. GOVERNMENT OBLIGATIONS. Investments in U.S. Government Obligations are not
all backed by the "full faith and credit" of the United States Government. Some
are backed only by the rights of the issuer to borrow from the U.S. Treasury and
others are supported only by the credit of the issuing instrumentality. No
assurance can be given that the U.S. Government would lend money to or otherwise
provide financial support to U.S. Government sponsored instrumentalities.
    
 
   
MARKET RISKS. Because the funds may invest in debt obligations which are traded
on securities exchanges, the value of each fund's portfolio will be affected by
changes in the stock markets. At times, the stock markets can be volatile and
stock prices can change substantially. This market risk will affect each fund's
net asset value per share, which will fluctuate as the values of each fund's
portfolio securities change. Prices do not always change uniformly or at the
same time and the various stock markets do not always move in the same direction
at the same time. Other factors specific to a particular company also affect the
price of that company's debt obligations (for example, poor earnings, loss of
major customers, or major litigation). The funds cannot always predict the
factors that will affect a security's
    
 
                                       30
<PAGE>
   
price. The funds, however, do attempt to limit market risk by diversifying their
investments. The funds diversify their investments by generally investing only a
small percentage of their assets in the debt obligations of any one company and
by not holding a substantial amount of the debt obligations of any one company.
    
 
   
REPURCHASE AGREEMENTS. In a repurchase agreement, a fund buys a security and
simultaneously sells it to the vendor for delivery at a future date. These
agreements are used primarily for cash purposes. A fund entering into a
repurchase agreement may lose money if the other party to the transaction fails
to pay the resale price on the delivery date. Such a default may delay or
prevent the fund from disposing of the underlying securities. The value of the
underlying securities may go down during the period in which the fund seeks to
dispose of them. Also, the fund may incur expenses while trying to sell the
underlying securities. Finally, the fund risks losing all or a part of the
income from the agreement.
    
 
   
OTHER RISKS. Each investor will be subject to all the risks normally attendant
to business operations, changes in general economic conditions, governmental
rules and fiscal policies, acts of God, and other factors beyond the control of
the funds' management.
    
 
   
YEAR 2000 RISKS. Many services provided to the funds and their shareholders
depend on the smooth functioning of computer systems. Many computer software
systems in use today cannot distinguish the year 2000 from the year 1900 because
of the way dates are encoded and calculated, referred to as the "Year 2000
Problem." The Year 2000 Problem could have a negative impact on handling
securities trades, payment of interest and dividends, pricing, and account
services. Like other mutual funds, financial and business organizations, and
individuals around the world, the funds could be adversely affected if the
computer systems used by SM&R (which acts as their investment adviser,
underwriter, custodian, and transfer agent) do not properly process and
calculate date-related information and data from and after January 1, 2000. SM&R
is taking steps to address the Year 2000 Problem with respect to the computer
systems that it uses and to obtain assurances that comparable steps are being
taken by any other service providers. At this time, however, there can be no
assurance that these steps will be sufficient to avoid any adverse impact on the
funds and their shareholders.

PURCHASES AND REDEMPTIONS
    
- -------------------------------------------------------------------
   
PURCHASING SHARES
    
 
   
You may purchase shares offered in this prospectus through certain financial
intermediaries (such as broker-dealers and mutual fund "marketplaces") that have
distribution agreements with SM&R. Such purchases will be at the offering price
for such shares determined as and when provided below (See "Pricing of Fund
Shares"). SM&R will send you a monthly confirmation for any month in which your
account is active. You should carefully review the monthly confirmation and
promptly report any discrepancies to SM&R. You may make subsequent purchases
through your registered representative or directly through SM&R at the following
address:
    
 
   
    Securities Management and Research, Inc.
    2450 South Shore Boulevard, Suite 400
    League City, Texas 77573
    
 
   
Certificates are not normally issued for shares of the funds in an effort to
minimize the risk of loss or theft. SM&R confirms investors' purchases and
credits such purchases to their accounts on the books maintained by SM&R.
Investors have the same rights of share ownership as they would if certificates
had been issued. Furthermore, a lost, stolen or destroyed certificate cannot be
replaced without obtaining a sufficient indemnity bond. The cost of such a bond
is borne by the investor and can be 2% or more of the value of the lost, stolen
or destroyed certificate.
    
 
   
OPENING AN ACCOUNT: To purchase shares, you must submit an account application
which includes the purchaser suitability form. If you would like to take
advantage of the electronic services available, please complete the electronic
transfer options section of the account application. Special forms are required
when establishing an IRA/ SEP or 403(b) plan. Please note that third party
checks will not be accepted to open a new account, except for IRA Rollover
checks that are properly endorsed.
    
 
   
MINIMUM PURCHASE REQUIREMENT: For Class J shares of the Government Bond and Tax
Free Funds, the minimum initial investment is $100 and all subsequent
investments must be at least $20. For the Primary and Money Market Funds, the
minimum initial investment is $1000 and the minimum amount of any subsequent
purchase is $100. The Company reserves the right to reject any purchase.

also under "Special Purchase Plans and Services."
    
 
   
PRICING OF FUND SHARES
    
 
   
GENERAL (HOW SHARES ARE PRICED). We determine each fund's offering price once
each business day. The offering price equals a fund's net asset value plus the
sales charge, if any. You may purchase shares offered in this prospectus without
a sales charge. Accordingly, the offering price for shares offered in this
prospectus is that fund's (or class') net asset value.
    
 
   
EFFECTIVE DATE OF PURCHASES AND REDEMPTIONS (WHEN SHARES ARE PRICED).
Calculation of net asset value is made once each business day at the close of
the New York Stock Exchange (currently 3:00 p.m. Central Time). Accordingly, the
price you pay or receive for shares of a fund depends, in part, on the day and
time you make your purchase or
    
 
                                       33
<PAGE>
   
redemption. On any business day, we will execute purchases and redemptions at
the applicable price determined that day if:
    
 
   
  - SM&R receives your order in proper form prior to the close of the Exchange;
    
 
   
  - a securities dealer having a dealer contract with SM&R receives your order
    prior to the close of the Exchange and reports your order to SM&R prior to
    SM&R's close of business (currently 4:30 p.m. Central Time) on the same day;
    or
    
 
   
  - for purchases, Moody National Bank receives your purchase payment by bank
    wire and reports it to SM&R prior to the close of the Exchange.
    
 
   
If we receive your order after the close of the Exchange, on customary national
business holidays, or on an SM&R business holiday, we will execute your purchase
or redemption at the price determined on the next business day. In unusual
circumstances, any fund may temporarily suspend the processing of sell requests,
or may postpone payment of proceeds for up to three business days or longer, as
allowed by federal securities laws.
    
 
   
SM&R BUSINESS HOLIDAYS. SM&R's business holidays are:
    
 
   
  - Good Friday
    
 
   
  - Memorial Day
    
 
   
  - Independence Day
    
 
   
  - Labor Day
    
 
   
  - Thanksgiving Day
    
 
   
  - the day after Thanksgiving
    
 
   
  - Christmas Day

The funds have implemented the following security procedures intended to protect
your account from losses resulting from unauthorized or fraudulent telephone
instructions: The caller must know:
    
 
   
 (i) the name of the fund or funds;
    
   
 (ii) all digits of the account number;
    
   
(iii) the exact name and address used in the registration(s); and
    
   
 (iv) the Social Security or Employer Identification Number listed on the
      account(s).
    
 
   
Additionally, we record all telephone transactions for your protection.
    
 
   
Neither the funds nor SM&R will be responsible for the authenticity of
transaction instructions received by telephone which comply with the current
security procedures and other requirements. SM&R believes that such security
procedures and other requirements are reasonable and, if followed, you should
bear the risk of any losses resulting from unauthorized or fraudulent telephone
transactions on your account(s).
    
 
   
AUTOMATIC INVESTMENT PLAN. Through this plan, a specified amount is
electronically transferred (via ACH) from your bank account and invested
monthly, bi-monthly, quarterly, or annually into the designated fund(s) at the
applicable offering price determined on the date of the electronic transfer.
    
 
   
GROUP SYSTEMATIC INVESTMENT PLAN. SM&R can establish a Group Systematic
Investment Plan with an employer having 5 or more participants under a single
payroll deduction arrangement. The Minimum Initial Investment amount requirement
per account is waived for such plans. However, all other investment amount
minimums apply. Contact SM&R for further information regarding such plans.
    
 
   
WEALTH ACCUMULATION ACCOUNT. Shareholders having account balances of at least
$2,500 in the Money Market Fund may open a Wealth Accumulation Account, which
will provide them with an automatic dollar cost averaging plan. Automatic
monthly purchases of the shares of other funds managed by SM&R may be made by
exchanges from the shareholder's Money Market Fund Wealth Accumulation Account.
Purchases of the other funds must be at least $50 and, unless terminated by the
shareholder, will continue as long as the balance of the Money Market Fund
Wealth Accumulation Account is sufficient. Additional investments may be made to
a Money Market
    
 
                                       36
<PAGE>
   
Fund account designated as a Wealth Accumulation Account to extend the purchase
period under the plan. However, if additional investments are received by SM&R
less than ten (10) business days prior to the 20th of the month, such
investments will not be available for use under the Wealth Accumulation Account
until the 20th of the following month. If the 20th of the month is an SM&R
holiday, the purchase will be processed on the next business day.
    
 
   
Purchases made will be subject to the applicable sales charge of the fund whose
shares are being purchased. Changes in amounts to be purchased, the funds being
purchased, and termination of a Wealth Accumulation Account will be made within
five (5) business days after written instructions are received by SM&R in proper
form (I.E., signed by the owner(s) of record exactly as registered).
    
 
   
Shareholders' rights to make additional investments, to exchange shares, and to
redeem shares in the Money Market Fund and any of the funds managed by SM&R are
not affected by a shareholder's participation in a Wealth Accumulation Account.
However, check writing privileges and expedited redemption by telephone are not
available for the Money Market Fund accounts designated as a part of the Wealth
Accumulation Account.
    
 
   
Primary Fund shareholders that opened a Primary Fund Wealth Accumulation Account
prior to December 31, 1998 will be permitted to continue using the Account
subject to the terms applicable to a Money Market Fund Wealth Accumulation
Account, described above.
    
 
   
EXCHANGE PRIVILEGE. As an investor in a fund, you are permitted to exchange
shares that you own in a fund with shares of another fund managed by SM&R
without the payment of an exchange fee, subject to certain conditions. EXCHANGES
BETWEEN A FUND AND ANOTHER FUND MANAGED BY SM&R ARE AVAILABLE ONLY IN STATES
WHERE THE APPLICABLE FUNDS ARE REGISTERED AND THE EXCHANGE MAY BE LEGALLY MADE.
YOU SHOULD CONTACT SM&R TO DETERMINE WHETHER A FUND IS REGISTERED IN A
PARTICULAR STATE.
    
 
   
GOVERNMENT BOND FUND AND TAX FREE FUND. You may exchange Class J shares that you
own in the Government Bond or Tax Free Fund, without an exchange fee, for shares
of the corresponding class of another fund managed by SM&R. You also may
exchange your Class J shares for shares of the Money Market or Primary Fund,
provided that you meet any minimum investment requirement for the
    
 
                                       37
<PAGE>
   
shares you wish to acquire. You may exchange Class J shares of the Government
Bond or Tax Free Fund for shares of another class of that fund, provided that
you pay any sales charge applicable to the acquired shares.
    
 
   
PRIMARY FUND AND MONEY MARKET FUND. You may exchange shares you own in the
Primary Fund for shares of the Money Market Fund, and vise versa. You may
exchange shares you own in the Primary or Money Market Fund for shares of a
class of another fund managed by SM&R, provided you pay any sales charge
applicable to the acquired shares.
    
 
   
You may acquire, through an exchange, shares of a class with a contingent
deferred sales charge. If you redeem those shares, the relevant contingent
deferred sales charge, if any, will be calculated from the date that you
initially purchased the original shares, rather than from the date of exchange.
    
 
   
You may request an exchange by telephone or in writing. In order to exchange
shares, the following requirements must be met:
    
 
   
(a) the exchange must be made between accounts having identical registrations
    and addresses;
    
 
   
(b) the shares of the fund acquired through exchange must be qualified for sale
    in the state in which you reside;
    
 
   
(c) the dollar amount of the exchange must meet the minimum investment
    requirement applicable to the shares of the fund that you would acquire
    through the exchange;
    
 
   
(d) SM&R must have received full payment for the shares being exchanged;
    
 
   
(e) your account must have been coded to reflect your certified taxpayer
    identification number, or, if applicable, an appropriate Internal Revenue
    Service Form W-8 (certificate of foreign status) or Form W-9 (certifying
    exempt status);
    
 
   
(f) any shares that you wish to exchange must have been held for at least ten
    (10) business days;
    
 
   
(g) certificates representing shares, if any, are returned before such shares
    are exchanged; and
    
 
   
(h) you have received a prospectus for the shares you receive in the exchange.
    
 
                                       38
<PAGE>
   
The exchange privilege is not an option or right to purchase shares but is
permitted under the respective policies of the participating funds, and may be
modified or discontinued by the participating funds or by SM&R at any time. ANY
GAIN OR LOSS REALIZED ON AN EXCHANGE OR RE-EXCHANGE MAY BE RECOGNIZED FOR
FEDERAL AND STATE INCOME TAX PURPOSES. YOU SHOULD CONSULT YOUR TAX ADVISOR FOR
THE TAX TREATMENT AND EFFECT OF EXCHANGES.
    
 
   
EXCESSIVE TRADING. Frequent trades, involving either substantial fund assets or
a substantial portion of your account or accounts controlled by you, can disrupt
management of the Company and raise the Company's expenses. We currently define
"excessive trading" as exceeding one purchase and sale involving the same fund
within any 120-day period.
    
 
   
For example, you are in Fund X. You can move substantial assets from Fund X to
Fund Y and, within the next 120 days, sell your shares in Fund Y to return to
Fund X or move to Fund Z. If you exceed the number of trades described above,
you may be barred indefinitely from further transactions between the
participating funds.
    
 
   
There are two types of transactions exempted from the excessive trading
guidelines. They are (1) redemptions that are not part of exchanges and (2)
systematic purchases or redemptions.
    
 
   
RETIREMENT PLANS
    
 
   
The following retirement plans may be funded with Class J shares of the
Government Bond Fund or with shares of the Primary and Money Market Funds:
    
 
   
  - Individual Retirement Accounts (IRAs), which include traditional IRAs, Roth
    IRAs, Education IRAs, and SIMPLE IRAs,
    
 
   
  - Simplified Employee Pension Plans (SEPs),
    
 
   
  - 403(b) Custodial Accounts (TSAs), and
    
 
   
  - corporate retirement plans.
    
 
   
These plans allow you to shelter investment income from federal income tax while
saving for retirement. Information concerning IRAs and TSAs, and the forms
necessary to adopt such plans, can be obtained by contacting your registered
representative. A regular fund application should be used when establishing a
corporate retirement plan. In connection with retirement plans, the minimum
initial
    
 
                                       39
<PAGE>
   
purchase for each fund is $100. (See "Purchasing Shares" for the minimum initial
and subsequent purchase requirements.) SM&R acts as trustee or custodian for
IRAs, SEPs, and TSAs for the Company. An annual custodial fee of $7.50 per
account will be charged for any part of a calendar year in which an investor has
an IRA, SEP, or TSA in the Company and will be automatically deducted from each
account. An individual considering a retirement plan may wish to consult with an
attorney or tax adviser.
    
 
   
Because IRAs, SEPs, TSAs, and other qualified plans are exempt from federal
income tax, they will be unable to benefit from the general tax-exempt nature of
the Tax Free Fund. Accordingly, the Tax Free Fund is not generally considered to
be suited for such plans or persons.
    
 
   
DIVIDENDS, DISTRIBUTIONS, AND TAXES
    
 
   
DIVIDENDS.
    
 
   
GOVERNMENT BOND AND TAX FREE FUNDS. The Government Bond and Tax Free Funds will
declare and pay dividends from net investment income monthly and net realized
short-term or long-term capital gains, if any, annually. In order to be entitled
to a dividend, an investor must have acquired shares of a fund prior to the
close of business on the record date. A shareholder should be cautioned,
however, before purchasing shares of a fund immediately prior to a distribution.
Dividends and distributions paid by the funds have the effect of reducing net
asset value per share on the record date by the amount of the payment.
Therefore, a dividend or distribution of record shortly after the purchase of
shares by an investor represents, in substance, a return of capital.
    
 
   
PRIMARY AND MONEY MARKET FUNDS. At 3:00 p.m. Central Time, on each day that the
Exchange is open for trading other than SM&R's business holidays described
above, the Primary and Money Market Funds each will declare a dividend of all of
its net investment income to shareholders of record on that date. Such dividends
will be paid monthly.
    
 
   
DIVIDEND REINVESTMENTS. Dividends and capital gains will be automatically
reinvested at net asset value in additional shares of the fund making such
distribution unless SM&R is instructed otherwise in writing. Distributions not
reinvested are paid by check or transmitted to your bank account through an ACH
transaction, if elected. If the
    
 
                                       40
<PAGE>
   
Postal Service cannot deliver your check, or if your check remains uncashed for
six months, the funds reserve the right to reinvest your distribution check in
your account at the net asset value on the business day of the reinvestment and
to reinvest all future distributions in shares of the applicable fund(s).
Dividends and capital gains declared in December to shareholders of record in
December and paid the following January will be taxable to shareholders as if
received in December. This is a convenient way to accumulate additional shares
and maintain or increase the shareholder's earning base. Of course, any shares
so acquired remain at market risk.
    
 
   
Shareholders have the right to change their election with respect to the receipt
of distributions by notifying SM&R in writing, but any such change will be
effective only as to distributions for which the record date is seven or more
business days after SM&R has received the shareholder's written request.
    
 
   
TAXABILITY OF DIVIDENDS. Dividends you receive from the Government Bond,
Primary, and Money Market Funds, whether reinvested or taken as cash, are
generally considered taxable. A fund's long-term capital gains distributions are
taxable as capital gains; dividends from other sources are generally taxable as
ordinary income. Some dividends paid in January may be taxable as if they had
been paid the previous December. The Form 1099 that is mailed to you every
January details your dividends and their federal tax category, although you
should verify your tax liability with your tax professional.
    
 
   
The Tax Free Fund intends to distribute tax-exempt dividends that shareholders
may exclude from their gross income for federal income tax purposes. However,
the Tax Free Fund may invest a portion of its assets in securities that generate
income that is not exempt from federal or state income tax. Income exempt from
federal tax may be subject to state and local income tax. Any capital gains
distributed by the Tax Free Fund may be taxable. Also, you should also keep in
mind that certain income from the Tax Free Fund may be subject to the federal
alternative minimum tax.
    
 
   
BACKUP WITHHOLDING. Backup withholding of federal income tax may be applied at
the rate of 31% from taxable dividends, distributions, and redemption proceeds
(including exchanges) if you fail to furnish the Company with a correct and
properly certified Social Security or Employer Identification Number when you
sign your application, or if you underreport your income to the Internal Revenue
Service.
    
 
                                       41
<PAGE>
   
TAXABILITY OF TRANSACTIONS. Any time you sell or exchange shares, it is
considered a taxable event for you. Depending on the purchase price and the sale
price of the shares you sell or exchange, you may have a gain or a loss on the
transaction. You are responsible for any tax liabilities generated by your
transactions. You should consult with a tax advisor concerning the tax reporting
requirements in effect on the redemption or exchange of such shares.
    
 
   
REDEEMING SHARES
    
 
   
You can redeem fund shares at the net asset value determined on the date the
request is received by SM&R in proper form. A redemption request must be
addressed to Securities Management and Research, Inc., 2450 South Shore
Boulevard, Suite 400, League City, Texas 77573.
    
 
   
If uncertain of the redemption requirements, investors should call Investor
Services or write SM&R. Payment will be made as soon as practicable and normally
within seven days after receipt of a redemption request in proper form. We
currently charge a fee in the amount of $8.00 for redemptions by wire under
$5,000.
    
 
   
If the shares being redeemed were purchased by wire, certified check, money
order, or other immediately available funds, redemption proceeds will be mailed
no later than the seventh calendar day following receipt. For shares purchased
by a personal check or ACH transfer, SM&R will process your redemption but will
generally delay sending you the proceeds for up to ten (10) business days to
allow the check or transfer to clear.
    
 
   
TELEPHONE REDEMPTIONS. You may request redemptions by telephone if you have
completed the account application and requested this option. This redemption
feature can only be used if:
    
 
   
(a) the redemption proceeds are to be mailed to the address of record or wired
    to the pre-authorized bank account indicated on the account application;
    
 
   
(b) there has been no change of address of record or pre-authorized bank account
    within the preceding 30 business days;
    
 
   
(c) the shares to be redeemed are not in certificate form;
    
 
   
(d) the security procedures discussed under "Special Purchase Plans And
    Services--Exchange Privilege" have been met; and
    
 
                                       42
<PAGE>
   
(e) the proceeds of the redemption do not exceed $25,000.
    
 
   
SYSTEMATIC WITHDRAWAL PLAN. The Company has a Systematic Withdrawal Plan
("Withdrawal Account"), which permits shareholders having an account value of
$5,000 or more to automatically withdraw a minimum of $50 monthly or each
calendar quarter on or about the 20th of the applicable month. Shareholders
maintaining a Withdrawal Account may elect to have the withdrawal proceeds
automatically deposited in their pre-authorized bank account via an ACH
transaction. This is accomplished by completing the relevant section of the
account application and returning it to SM&R. See "Special Purchase Plans and
Services--Electronic Transfers" for additional information. Dividends and
capital gains distributions will automatically be reinvested in additional
shares at net asset value. As with other redemptions, a withdrawal is a sale for
federal income tax purposes. The Systematic Withdrawal Plan will automatically
terminate if all shares are liquidated or withdrawn from the account.
Certificates are not issued for shares held in a Withdrawal Account and
certificates held, if any, must be surrendered when shares are transferred to a
Withdrawal Account. No account covered by a Letter of Intent can be changed to a
Systematic Withdrawal Plan until such time as the Letter of Intent is fulfilled
or terminated, nor can an account under a Systematic Withdrawal Plan be placed
under a Letter of Intent.
    
 
   
For further information about the "Systematic Withdrawal Plan," contact a
registered representative or SM&R.
    
 
   
"PROPER FORM" means the request for redemption must include:
    
 
   
(1) your share certificates, if issued;
    
 
   
(2) your letter of instruction or a stock assignment specifying the fund,
    account number, and number of shares or dollar amount to be redeemed. Both
    share certificates and stock powers, if any, must be endorsed and executed
    exactly as the fund shares are registered. It is suggested that certificates
    be returned by certified mail for your protection;
    
 
   
(3) any required signature guarantees (see "Signature Guarantees" below); and
    
 
                                       43
<PAGE>
   
(4) other supporting legal documents, if required in the case of estates,
    trusts, guardianships, divorce, custodianships, corporations, partnerships,
    pension or profit sharing plans, retirement plans, and other organizations.
    
 
   
Please keep in mind that as a shareholder, it is your responsibility to ensure
that all requests are submitted to the Company's transfer agent in proper form
for processing.
    
 
   
SIGNATURE GUARANTEES. A signature guarantee verifies the authenticity of your
signature. Signature guarantees are required when:
    
 
   
(1) the proceeds of the redemption exceed $25,000;
    
 
   
(2) the proceeds (in any amount) are to be paid to someone OTHER THAN the
    registered owner(s) of the account;
    
 
   
(3) the proceeds (in any amount) are to be sent to any address OTHER THAN the
    shareholder's address of record, pre-authorized bank account or exchanged to
    one of the other funds managed by SM&R; or
    
 
   
(4) the Company or its transfer agent believes a signature guarantee would
    protect against potential claims based on the transfer instructions,
    including, when the authority of a representative of a corporation,
    partnership, association, or other entity has not been established to the
    satisfaction of the Company or transfer agent.
    
 
   
You should be able to obtain an acceptable signature guarantee from a bank,
broker, dealer, municipal securities dealer or broker, government securities
dealer or broker, credit union, national securities exchange, or registered
securities association. WITNESSING OR NOTARIZATION IS NOT SUFFICIENT.
    
 
   
TEXAS OPTIONAL RETIREMENT PROGRAM. You may not redeem shares of the Government
Bond Fund, Primary Fund, and Money Market Fund in any account established under
the Texas Optional Retirement Program, unless SM&R receives satisfactory
evidence from the state that one of the following conditions exist:
    
 
   
(1) death of the employee;
    
 
   
(2) termination of service with the employer; or
    
 
   
(3) retirement of employee.
    
 
                                       44
<PAGE>
   
CHECK WRITING OPTION. Check writing is available in the Money Market Fund to
investors having an account value of $1,000 or more. $250 is the minimum check
amount under the check writing option. This option is not available on IRAs,
SEPs, or TSAs. Shareholders wishing to avail themselves of this option must
complete the check writing option signature card in the Prospectus. After
obtaining specimen signatures and the fully executed card, SM&R will order
checks and arrange for the shareholder's checks to be honored by a bank.
Investments made by personal check or third party check will be held for fifteen
(15) business days following the investment during which time checks may not be
drawn on the amount of such investment. This service may be terminated or
suspended or additional charges may be imposed for this service. Shareholders
will be provided the initial checkbook free of charge. There will be a $5 fee
for re-orders. Shareholders will be allowed to write ten (10) checks free each
calendar quarter.
    
 
   
When a check is presented for payment, SM&R, as the shareholder's agent, will
cause each fund to redeem a sufficient number of full and fractional shares to
cover the amount of the check. Shareholders will continue to be entitled to
dividends on their shares up to the time the check is presented to SM&R for
payment. If the amount of the check is greater than the value of the shares held
in the shareholder's account for more than fifteen (15) business days at the
time the check is presented for payment, the check will be returned to the payee
as not being covered by sufficient funds, and the shareholder will be subject to
extra charges as a result.
    
 
   
Primary Fund shareholders that had check writing privileges prior to December
31, 1998 will be permitted to continue writing checks on the Primary Fund
subject to the terms applicable to the Money Market Fund described above.
SHAREHOLDERS USING THE PRIMARY FUND CHECK WRITING OPTION SHOULD BE AWARE THAT
WRITING A CHECK IS A REDEMPTION OF SHARES. THOSE SHARES MAY BE WORTH LESS WHEN
THE CHECK IS PRESENTED FOR PAYMENT THAN WHEN THE CHECK WAS WRITTEN.
    
 
   
REDEMPTION OF SMALL ACCOUNTS. The Company reserves the right to redeem shares in
any account (which will be promptly paid to the shareholder) if, due to your
redemptions, the value of the account falls below $100 in the case of the
Government Bond and Tax Free Funds or $1,000 in the case of the Primary and
Money Market Funds. You will be notified that the value of your account is less
than the required minimum indicated above and allowed at least 60
    
 
                                       45
<PAGE>
   
days to make an additional investment to increase the value of your account
above the required minimum. The Board of Directors may, from time to time,
change such required minimum investment.
    
 
   
RIGHTS RESERVED BY THE COMPANY. The Company, acting through its transfer agent,
reserves the right:
    
 
   
  - to waive or lower investment minimums;
    
 
   
  - to accept initial purchases by telephone from a registered representative;
    
 
   
  - to refuse any purchase order;
    
 
   
  - to cancel or rescind any purchase or exchange at any time prior to receipt
    by the shareholder of written confirmation or, if later, within five (5)
    business days of the transaction;
    
 
   
  - to freeze an account and suspend account services when notice has been
    received of a dispute involving the account owners or other parties or there
    is reason to believe a fraudulent transaction may occur;
    
 
   
  - to restrict or refuse the use of faxed redemptions where there is a question
    as to the validity of the request or proper documents have not been
    received;
    
 
   
  - to otherwise modify the conditions of purchase and any services at any time;
    or
    
 
   
  - to act on instructions not believed to be genuine.

THE FUNDS AND MANAGEMENT
    
- -------------------------------------------------------------------
 
   
INVESTMENT ADVISOR
    
 
   
The Company's Board of Directors has delegated to Securities Management and
Research, Inc. ("SM&R"), the funds' investment adviser, the management of the
funds' day-to-day business and affairs. In addition, SM&R invests the funds'
assets, provides administrative services, and serves as transfer agent,
custodian, dividend paying agent, and underwriter.
    
 
   
SM&R is a wholly-owned subsidiary of American National Insurance Company
("American National"). SM&R was incorporated in 1964 and has managed mutual
funds since 1966. SM&R does and may, from time to time, serve as investment
adviser to other clients including employee benefit plans, other investment
companies, banks, foundations and endowment funds.
    
 
   
Under the Advisory Agreements with the Company, SM&R is paid an investment
advisory fee, which is calculated separately for each fund, as compensation for
its services. The agreement provides that SM&R will receive advisory fees as set
forth below.
    
 
   
GOVERNMENT BOND FUND AND TAX FREE FUND. We deduct an investment advisory fee
from the value of the shares each day. We calculate this fee for the Government
Bond and Tax Free Funds at the annual rate as follows:

</TABLE>
    
 
   
MONEY MARKET FUND AND PRIMARY FUND. For the Money Market and Primary Funds, we
calculate the investment advisory fee at the annual rate of 0.50% of each fund's
average daily net asset value.
    
 
   
After applicable fee waivers, SM&R received total advisory fees from the
Government Bond Fund, Tax Free Fund, and Primary Fund for the fiscal year ended
August 31, 1998 which represented [____]%, [____]%, and [___]%, respectively, of
each such fund's average daily

net assets. The Money Market Fund was not in operation during the fiscal year
ended August 31, 1998.
    
 
   
ADMINISTRATIVE SERVICES
    
 
   
Under its Administrative Service Agreement with the Company, SM&R also receives
an administrative service fee from each fund at the annual rate of average daily
net asset values as follows:

REIMBURSEMENTS AND WAIVERS
    
 
   
SM&R has agreed to pay (or to reimburse each fund for) each fund's regular
operating expenses in excess of 1.25% (0.35% for the Money Market Fund) per year
of such fund's average daily net assets. Regular operating expenses include the
advisory fee and administrative service fee, if any, paid to SM&R, but do not
include 12b-1 fees, class-specific expenses, interest, taxes, commissions, and
other expenses incidental to portfolio transactions. SM&R received
administrative service fees of [___]% for the Government Bond Fund; [___]% for
the Primary Fund; and [___]% for the Tax Free Fund for the fiscal year ended
August 31, 1998 of each fund's average daily net assets. The Money Market Fund
was not in operation during the fiscal year ended August 31, 1998.
    
 
   
In order to improve the yield and total return of any fund of the Company, SM&R
may from time to time voluntarily waive or reduce all or any portion of its
advisory fee, administrative fee, and/or assume certain or all expenses of any
fund of the Company while retaining its ability to be reimbursed for such fees
prior to the end of the fiscal year. Fee waivers and/or reductions, other than
those stated in the Administrative Service Agreement, may be rescinded by SM&R
at any time without notice to investors. SM&R has agreed to continue to waive
the advisory fee for the Tax Free Fund and reimburse expenses incurred by the
Government Bond and Primary Funds to the extent that regular operating expenses
exceed average daily net assets as follows: 0.80% for the Primary Fund and 1.00%
for the Government Bond Fund.

FINANCIAL HIGHLIGHTS                                        GOVERNMENT BOND FUND
    
- -------------------------------------------------------------------
 
   
The following financial highlights table is intended to help you understand the
Government Bond Fund's financial performance for the past five years. Certain
information reflects financial results for a single share outstanding throughout
each period shown. The total returns in the table represent the rate that an
investor would have earned (or lost) on an investment in the Government Bond
Fund (assuming reinvestment of all dividends and distributions) prior to
addition of multiple classes of shares. This information is derived from the
financial statements of the Government Bond Fund which for the years ended
through August 31, 1997 have been audited by KPMG Peat Marwick LLP and for the
year ended August 31, 1998 has been audited by Tait, Weller & Baker, CPA. Each
independent auditor's report, along with the Government Bond Fund's financial
statements, are incorporated by reference into the Statement of Additional
Information, which is available upon request. IF MULTIPLE CLASSES OF SHARES OF
THE GOVERNMENT BOND FUND HAD BEEN IN EXISTENCE DURING THE PAST FIVE YEARS, THE
FINANCIAL PERFORMANCE OF CLASS J SHARES OF THE GOVERNMENT BOND FUND WOULD HAVE
BEEN LOWER THAN DEPICTED BECAUSE OF THE IMPOSITION OF DISTRIBUTION (12b-1) FEES.

The following financial highlights table is intended to help you understand the
Tax Free Fund's financial performance since inception. Certain information
reflects financial results for a single share outstanding throughout each period
shown. The total returns in the table represent the rate that an investor would
have earned (or lost) on an investment in the Tax Free Fund (assuming
reinvestment of all dividends and distributions) prior to addition of multiple
classes of shares. This information is derived from the financial statements of
the Tax Free Fund which for the years ended through August 31, 1997 have been
audited by KPMG Peat Marwick LLP and for the year ended August 31, 1998 has been
audited by Tait, Weller & Baker, CPA. Each independent auditor's report, along
with the Tax Free Fund's financial statements, are incorporated by reference
into the Statement of Additional Information, which is available upon request.
IF MULTIPLE CLASSES OF SHARES OF THE TAX FREE FUND HAD BEEN IN EXISTENCE DURING
THE PAST FIVE YEARS, THE FINANCIAL PERFORMANCE OF CLASS J SHARES OF THE TAX FREE
FUND WOULD HAVE BEEN LOWER THAN DEPICTED BECAUSE OF THE IMPOSITION OF
DISTRIBUTION (12b-1) FEES.

APPENDIX
    
 
   
(Description of Ratings Used in Prospectus)
    
- -------------------------------------------------------------------
 
   
BOND RATINGS
    
 
   
DESCRIPTION OF STANDARD & POOR'S CORPORATION'S BOND RATING:
    
 
   
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 obligations 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 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, which
       could lead to the obligor's inadequate capacity to meet its financial
       commitment on the obligation.
    
 
   
B     An obligation rated "B" is more vulnerable to nonpayment than obligations
       rated "BB," but the obligor currently has the capacity to meet its
       financial commitment on the obligation.
    
 
                                      A-1
<PAGE>
   
       Adverse business, financial, or economic conditions will likely impair
       the obligor's capacity or willingness to meet its financial commitment on
       the obligation.
    
 
   
DESCRIPTION OF MOODY'S INVESTOR'S SERVICE, INC.'S BOND RATINGS:
    
 
   
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-edge." 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,
       fluctuation of protective elements may be of greater amplitude, or there
       may be other elements present which make the long-term risks appear
       somewhat greater than in Aaa securities.
    
 
   
A     Bonds which are rated "A" possess many favorable investment attributes and
       are to be considered as upper medium grade obligations. Factors giving
       security to principal and interest are considered adequate but elements
       may be present which suggest a susceptibility to impairment sometime in
       the future.
    
 
   
Baa   Bonds which are rated "Baa" are considered as medium grade obligations,
       I.E., they are neither highly protected nor poorly secured. Interest
       payments and principal security appear adequate for the present, but
       certain protective elements may be lacking or may be characteristically
       unreliable over any great length of time. Such bonds lack outstanding
       investment characteristics and in fact have speculative characteristics
       as well.
    
 
   
Ba    Bonds which are rated "Ba" are judged to have speculative elements; their
       future cannot be considered as well assured. Often the protection of
       interest and principal payments may be very moderate and thereby not well
       safeguarded during both good and bad times over the future. Uncertainty
       of position characterizes bonds in this class.
    
 
                                      A-2
<PAGE>
   
B     Bonds which are rated "B" generally lack characteristics of the desirable
       investment. Assurance of interest and principal payments or of
       maintenance of other terms of the contract over any long period of time
       may be small.
    
 
   
DESCRIPTION OF FITCH INVESTORS SERVICE BOND RATINGS:
    
 
   
AAA  Obligations which have the highest rating assigned by Fitch IBCA on its
       national rating scale for that country. This rating is automatically
       assigned to all obligations issued or guaranteed by the sovereign state.
       Capacity for timely repayment of principal and interest is extremely
       strong, relative to other obligors in the same country.
    
 
   
AA   Obligations for which capacity for timely repayment of principal and
       interest is very strong relative to other obligors in the same country.
       The risk attached to these obligations differs only slightly from the
       country's highest rated debt.
    
 
   
A     Obligations for which capacity for timely repayment of principal and
       interest is strong relative to other obligors in the same country.
       However, adverse changes in business, economic or financial conditions
       are more likely to affect the capacity for timely repayment than for
       obligations in higher rated categories.
    
 
   
BBB  Obligations for which capacity for timely repayment of principal and
       interest is adequate relative to other obligors in the same country.
       However, adverse changes in business, economic or financial conditions
       are more likely to affect the capacity for timely repayment than for
       obligations in higher rated categories.
    
 
   
MUNICIPAL NOTE RATINGS
    
 
   
DESCRIPTION OF MOODY'S INVESTOR SERVICE INC.'S MUNICIPAL NOTE RATINGS:
    
 
   
MIG 1/VMIG 1 This designation denotes best quality. There is present strong
                protection by established cash flows, superior liquidity support
                or demonstrated broad-based access to the market refinancing.
    
 
                                      A-3
<PAGE>
   
MIG 2/VMIG 2 This designation denotes high quality. Margins of protection are
                ample although not so large as in the preceding group.
    
 
   
MIG 3/VMIG 3 This designation denotes favorable quality. All security elements
                are accounted for but there is lacking the undeniable strength
                of the preceding grades. Liquidity and cash flow protection may
                be narrow and market access for refinancing is likely to be less
                well established.
    
 
   
MIG 4/VMIG 4 This designation denotes adequate quality. Protection commonly
                regarded as required of an investment security is present and
                although not distinctly or predominantly speculative, there is
                specific risk.
    
 
   
DESCRIPTION OF STANDARD AND POOR'S MUNICIPAL NOTE RATINGS:
    
 
   
Until June 29, 1984, S&P used the same rating symbols for notes and bonds. After
June 29, 1984, for new municipal note issues due in three years or less the
ratings below usually will be assigned. Notes maturing beyond three years will
most likely receive a bond rating of the type recited above.
    
 
   
SP-1  Strong capacity to pay principal and interest. An issue determined to
       possess a very strong capacity to pay debt service is 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.
    
 
   
COMMERCIAL PAPER RATINGS
    
 
   
DESCRIPTION OF STANDARD & POOR'S CORPORATION'S THREE HIGHEST COMMERCIAL PAPER
RATINGS:
    
 
   
Commercial paper rated "A" by Standard & Poor's Corporation has the following
characteristics: Liquidity ratios are adequate to meet cash requirements.
Long-term senior debt is generally rated "A" or better. The issuer has access to
at least two additional channels of borrowing. Basic earnings and cash flow have
an upward trend with allowance made for unusual circumstances. Typically, the
issuer's industry is well established and the issuer has a strong position
within
    
 
                                      A-4
<PAGE>
   
the industry. The reliability and quality of management are unquestioned.
Relative strength or weakness of the above factors determine whether the
issuer's commercial paper is rated as follows:
    
 
   
A-1   This designation indicates that the degree of safety regarding timely
       payment is strong. Those issues determined to possess extremely strong
       safety characteristics are denoted with a plus sign (+) designation.
    
 
   
A-2   Capacity for timely payment on issues with this designation is
       satisfactory. However, the relative degree of safety is not as high as
       for issues designated 'A-1'.
    
 
   
DESCRIPTION OF MOODY'S INVESTORS SERVICE, INC.'S THREE HIGHEST COMMERCIAL PAPER
RATINGS:
    
 
   
Among the factors considered by Moody's Investors Service, Inc. is assigning
commercial paper ratings are the following: (1) evaluation of the management of
the issuer; (2) economic evaluation of the issuer's industry or industries and
an appraisal of the risks which may be inherent in certain areas; (3) evaluation
of the issuer's products in relation to competition and customer acceptance; (4)
liquidity; (5) amount and quality of long-term debt; (6) trend of earnings over
a period of ten years; (7) financial strength of a parent company and the
relationships which exist with the issuer; and (8) recognition of the management
of obligations which may be present or may arise as a result of public interest
questions and proportions to meet such obligations. Relative differences in
strength and weakness in respect to these criteria would establish a rating in
one of three classifications; "P-1," "P-2" or "P-3."
    
 
   
DESCRIPTION OF FITCH INVESTORS SERVICE COMMERCIAL PAPER, MEDIUM-TERM NOTES, AND
MUNICIPAL AND INVESTMENT NOTES.
    
 
   
F-1+  Exceptionally Strong Credit Quality. Issues assigned this rating are
       regarded as having the strongest degree of assurance for timely payment.
    
 
   
F-1   Very Strong Credit Quality. Issues assigned this rating reflect an
       assurance of timely payment only slightly less in degree than issues
       rated "F-1+."
    
 
   
F-2   Good Credit Quality. Issues assigned this rating have a satisfactory
       degree of assurance for timely payment, but the margin of safety is not
       as great as for issues assigned "F-1+" and "F-1" ratings.
    
 
                                      A-5
<PAGE>
   
F-3   Fair Credit Quality. Issues assigned this rating have characteristics
       suggesting that the degree of assurance for timely payment is adequate,
       however, near-term adverse changes could cause these securities to be
       rated below investment grade.
    
 
   
F-5   Weak Credit Quality. Issues assigned this rating have characteristics
       suggesting a minimal degree of assurance for timely payment and are
       vulnerable to near-term adverse changes in financial and economic
       conditions.
    
 
   
DESCRIPTION OF DUFF & PHELP'S TWO HIGHEST COMMERCIAL RATINGS:
    
 
   
Duff & Phelp's commercial paper ratings place emphasis on liquidity, considering
not only cash from operations, but access to alternative sources of funds,
including trade credit, bank lines and capital markets. Relative differences in
strength and weakness is rated by Duff & Phelp's as Duff-1 or Duff-2; Duff-1
being the highest commercial paper rating and Duff-2 being the second highest
rating.
    
 
   
DESCRIPTION OF THOMSON BANKWATCH, INC.'S TWO HIGHEST COMMERCIAL RATINGS:
    
 
   
Thomson Bankwatch, Inc.'s ratings of United States commercial banks, thrifts,
and non-bank banks, non-United States banks, and broker-dealers are based upon
among other things, five years's financial information and the issuer's most
recent regulatory filings. Relative differences in strength and weakness are
rated by Thomson Bankwatch, Inc.
    
 
   
TBW-1 The highest category; indicates a very high likelihood that principal and
       interest will be paid on a timely basis.
    
 
   
TBW-2 The second-highest category; while the degree of safety regarding timely
       repayment of principal and interest is strong, the relative degree of
       safety is not as high as for issues rated TBW-1.

RISK/RETURN SUMMARY                                    SM&R GOVERNMENT BOND FUND
    
- -------------------------------------------------------------------
 
   
GOVERNMENT BOND FUND'S INVESTMENT OBJECTIVE
                   To provide as high a level of current income,
                   liquidity, and safety of principal as is consistent with
                   prudent investment risks through investment in a portfolio
                   consisting primarily of securities issued or guaranteed by
                   the U.S. Government, its agencies, or instrumentalities.
    
 
   
GOVERNMENT BOND FUND'S PRINCIPAL INVESTMENT STRATEGIES
                   The Government Bond Fund normally invests at
                   least 65% of its assets in securities issued or guaranteed by
                   the U.S. Government, its agencies, or instrumentalities.
                   These may include Treasuries and mortgage-backed securities,
                   such as Ginnie Maes, Freddie Macs, and Fannie Maes. This fund
                   may also invest assets in collateralized mortgage
                   obligations.
    
 
   
                   The Government Bond Fund may invest in zero coupon bonds,
                   which are U.S. Government obligations. The fund may also
                   invest in commercial paper, certificates of deposit,
                   corporate debt securities rated "A" or higher, and repurchase
                   agreements.
    
 
   
PRINCIPAL RISKS OF INVESTING IN THE GOVERNMENT BOND FUND
                   You could lose money on your investment in the
                   Government Bond Fund, or it could underperform other
                   investments, if any of the following occurs:
    
   
                   - interest rates rise (thus causing a decline in the market
                     value of debt securities)
    
   
                   - the worldwide demand for U.S. government securities falls
    
   
                   - interest rates fall enough to prompt an unexpected number
                     of people to refinance (or prepay) their mortgages
    
   
                   - interest rates rise enough to cause fewer people than
                     expected to repay their mortgages early
    
   
                   - if any bonds the fund owns are downgraded in credit rating
                     or go into default

                   The Government Bond Fund may be
                   appropriate if you:
    
   
                   - are seeking a regular stream of income to meet current
                     needs

RISK/RETURN SUMMARY                                           SM&R TAX FREE FUND
    
- -------------------------------------------------------------------
 
   
TAX FREE FUND'S INVESTMENT OBJECTIVE
                   To provide as high a level of interest income
                   largely exempt from federal income taxes as is consistent
                   with preservation of capital through investment of at least
                   80% of its net assets in tax-exempt securities during normal
                   market conditions.
    
 
   
TAX FREE FUND'S PRINCIPAL INVESTMENT STRATEGIES
                   The Tax Free Fund invests primarily in tax-
                   exempt securities. During normal market conditions, this fund
                   invests at least 80% of its assets in municipal securities
                   that pay interest exempt from federal income taxes. This fund
                   may not invest more than 20% of its assets in UNRATED
                   municipal securities. These securities may be less liquid
                   than comparably rated municipal securities and involve
                   somewhat greater risk. This fund may also invest up to 20% of
                   its assets in Government guaranteed taxable bonds, highly
                   rated corporate bonds, or commercial paper.
    
 
   
PRINCIPAL RISKS OF INVESTING IN THE TAX FREE FUND
                   You could lose money on your investment in the
                   Tax Free Fund, or it could underperform other investments, if
                   any of the following occurs:
    
   
                   - interest rates rise (thus causing a decline in the market
                     value of debt securities)
    
   
                   - if any bonds the fund owns are downgraded in credit rating
                     or go into default
    
   
                   - certain securities become harder to value or to sell at a
                     fair price
    
 
   
                   ALSO, SOME OF YOUR DIVIDEND INCOME MAY BE TAXABLE.

WHO MAY WANT TO INVEST IN THE TAX FREE FUND
    
                   The Tax Free Fund may be appropriate if you:
   
                   - are willing to sacrifice some investment return for income
                     exempt from federal income tax and, under certain
                     conditions, exempt from state and local taxes
    
   
                   - are in a high tax bracket (28% and up)

RISK/RETURN SUMMARY                                            SM&R PRIMARY FUND
    
- -------------------------------------------------------------------
 
   
PRIMARY FUND'S INVESTMENT OBJECTIVE
                   To seek maximum current income consistent
                   with capital preservation and liquidity through investment
                   primarily in commercial paper.
    
 
   
PRIMARY FUND'S PRINCIPAL INVESTMENT STRATEGIES
                   The Primary Fund invests primarily in
                   commercial paper. Commercial paper is short-term unsecured
                   promissory notes issued by corporations. This fund will only
                   invest in commercial paper rated in one of the two highest
                   rating categories.
    
 
   
                   The Primary Fund may also invest in:
    
   
                   - U.S. Government obligations;
    
   
                   - corporate debt obligations maturing in five years or less
                     and rated "A" or higher;
    
   
                   - certificates of deposit; and
    
   
                   - repurchase agreements.
    
 
   
PRINCIPAL RISKS OF INVESTING IN THE PRIMARY FUND
                   You could lose money on your investment in the
                   Primary Fund, or it could underperform other investments, if
                   any of the following occurs:
    
   
                   - interest rates rise (thus causing a decline in the market
                     value of debt securities)
    
   
                   - if any of the fund's investments are downgraded in credit
                     rating or go into default
    
 
   
                   By limiting its investments as described above, the Primary
                   Fund may not achieve as high a level of current income as a
                   fund investing in lower-rated securities or longer-term
                   securities.

MONEY MARKET FUND'S INVESTMENT OBJECTIVE
                   To seek the highest current income consistent
                   with the preservation of capital and maintenance of
                   liquidity.
    
 
   
MONEY MARKET FUND'S PRINCIPAL INVESTMENT STRATEGIES
                   The Money Market Fund seeks to achieve its
                   objective by investing in high-quality short-term money
                   market instruments, including: U.S. Government obligations,
                   certificates of deposit, banker's acceptances, commercial
                   paper, collateralized mortgage obligations, and corporate
                   bonds and notes. This fund limits its investments to those
                   short-term securities that it determines present minimal
                   credit risk and meet certain rating requirements (in the two
                   highest short-term rating categories).
    
 
   
PRINCIPAL RISKS OF INVESTING IN THE MONEY MARKET FUND
                   The Money Market Fund is subject to the
                   following risks:
    
   
                   - that interest rates may rise (thus causing a decline in the
                     market value of debt securities)
    
   
                   - that the fund's investments may be downgraded in credit
                     rating or go into default
    
 
   
                   However, the risks of investment in the Money Market Fund may
                   be expected to be less than for other mutual funds. By
                   limiting its investments as described above, this fund may
                   not achieve as high a level of current income as a fund
                   investing in lower-rated securities. Also, there is a remote
                   possibility that this fund's share value could fall below
                   $1.00, which could reduce the value of your account.

WHO MAY WANT TO INVEST IN THE MONEY MARKET FUND
                   The Money Market Fund may be appropriate if
                   you:
    
   
                   - require stability of principal
    
   
                   - are seeking a mutual fund for the cash portion of an asset

                   - are investing for retirement or other goals that are many
                     years in the future
    
   
                   - are investing for growth or maximum current income
    
   
AN INVESTMENT IN THE MONEY MARKET FUND IS NOT INSURED OR GUARANTEED BY THE
FEDERAL DEPOSIT INSURANCE CORPORATION OR ANY OTHER GOVERNMENT AGENCY. ALTHOUGH
THE MONEY MARKET FUND SEEKS TO PRESERVE THE VALUE OF YOUR INVESTMENT AT $1.00
PER SHARE, IT IS POSSIBLE TO LOSE MONEY BY INVESTING IN THE MONEY MARKET FUND.

RISK/RETURN SUMMARY
    
- -------------------------------------------------------------------
 
   
TYPES OF INVESTMENT RISK
    
 
   
As indicated above, each of the four funds may be subject to certain of the
following types of risks:
    
 
   
CREDIT RISK. The risk that the issuer of a security, or a party to a contract,
will default or otherwise not honor a financial obligation.
    
 
   
INTEREST RATE RISK. The risk of declines in market value of an income-bearing
investment due to changes in prevailing interest rates. With fixed-rate
securities, a rise in interest rates typically causes a decline in market
values, while a fall in interest rates typically causes an increase in market
values.
    
 
   
LIQUIDITY RISK. The risk that certain securities or other investments may be
difficult or impossible to sell at the time the fund would like to sell them or
at the price the fund values them. The fund may have to sell at a lower price,
sell other securities instead, or forego an investment opportunity, any of which
could have a negative effect on fund management or performance.
    
 
   
MANAGEMENT RISK. The risk that a strategy used by a fund's management may fail
to produce the intended result. This risk is common to all mutual funds.
    
 
   
MARKET RISK. The risk that the market value of a security may move up and down,
sometimes rapidly and unpredictably. The fluctuations may cause a security to be
worth less than the price originally paid for it, or less than it was worth at
an earlier time. Market risk may affect a single issuer, industry, sector of the
economy, or the market as a whole. This risk is common to all stocks and bonds
and the mutual funds that invest in them.
    
 
   
PREPAYMENT AND EXTENSION RISK. PREPAYMENT RISK is the risk that an unexpected
fall in prevailing interest rates will shorten the life of an outstanding
mortgage-backed security by increasing the actual or expected number of mortgage
prepayments, thereby reducing the security's value. EXTENSION RISK is the risk
that an unexpected rise in prevailing interest rates will extend the life of an
outstanding mortgage-backed security by reducing the actual or expected number
of mortgage prepayments, thereby reducing the security's value.

BAR CHART AND PERFORMANCE TABLE
    
 
   
The bar charts and performance tables shown below provide some indication of the
risks of investing in the funds and the variability of returns by showing each
fund's performance for each year since inception and by showing how each fund's
average annual returns for certain periods compare to those of a broad-based
securities market index. Because the Money Market Fund was not in operation
during these periods, it is not included in the bar chart or the performance
table.
    
 
   
The returns shown are based on an investment in the funds prior to the creation
of multiple classes of shares, but do not reflect any sales loads that would be
imposed on the purchase or sale of any shares.
    
 
   
Past performance is not necessarily an indication of how the funds will perform
in the future.

NOTES TO THE TABLE OF FEES AND EXPENSES
    
 
   
(1) You pay a sales charge of 4.5% on initial investments in Class T shares of
    less than $100,000. You pay a reduced sales charge at certain breakpoints,
    as follows:
    
 
   
    - 3.50% on initial investments of at least $100,000 but less than $250,000
    
 
   
    - 2.50% on initial investments of at least $250,000 but less than $500,000
    
 
   
    - zero on initial investments of $500,000 or more
    
 
   
(2) You pay an $8.00 transaction fee for each expedited wire redemption.
    
 
   
(3) "Other Expenses" include the 0.25% Administrative Service Fee. "Other
    Expenses" for Class T shares are based on the expenses and average net
    assets of the Government Bond Fund and the Tax Free Fund for the fiscal year
    ended August 31, 1998. "Other Expenses" shown for the Money Market Fund are
    estimated for the current fiscal year ending August 31, 1999.
    
 
   
(4) The Fee Table does not reflect any fees waived or expenses assumed either
    contractually or voluntarily by the funds' manager, Securities Management
    and Research, Inc. ("SM&R"). Pursuant to the Administrative Service
    Agreement, SM&R will pay (or reimburse) each fund for regular operating
    expenses in excess of 1.25% (0.35% for the Money Market Fund) per year of
    such fund's average daily net assets. Regular operating expenses include the
    advisory fee and administrative fee, but do not include any 12b-1 fee or
    class-specific expenses.
    
 
   
    SM&R may also waive fees or assume expenses on a voluntary basis. During the
    fiscal year ended August 31, 1998, SM&R voluntarily waived fees of [___]%,
    [___]%, and [___]% for the Government Bond Fund, Primary Fund, and Tax Free
    Fund, respectively, and reimbursed expenses of [___]% for the Tax Free Fund.
    SM&R intends to continue to voluntarily waive the advisory fee for the Tax
    Free Fund. SM&R also intends to reimburse regular operating expenses that
    exceed average daily net assets as follows: 0.80% for the Primary Fund and
    1.00% for the

    reimbursement of expenses at any time without notice.
    
 
   
    The following table shows fees and expenses for the Government Bond,
    Primary, and Tax Free Funds for the year ended August 31, 1998 taking into
    account fee waivers and expense reimbursements. For the Money Market Fund,
    they are estimates considering estimated fee waivers and expense
    reimbursements for the year ending August 31, 1999.

EXAMPLES OF EXPENSES
    
 
   
These examples are intended to help you compare the cost of investing in the
funds with the cost of investing in other mutual funds. These examples assume
that you invest $10,000 in each fund and applicable class thereof for the time
periods indicated, based on expenses before fee waivers and expense
reimbursements. These examples also assume that your investment has a 5% return
each year and that the funds' operating expenses remain the same. YOUR ACTUAL
COSTS MAY BE HIGHER OR LOWER THAN SHOWN.

SHARES OF THE FUNDS
    
- -------------------------------------------------------------------
 
   
SM&R Investments, Inc., formerly known as SM&R Capital Funds, Inc. (the
"Company" or "we") offers four separate investment portfolios. The Money Market
and Primary Funds each consist of a single class of shares offered at net asset
value and do not impose any sales charges or distribution and service (12b-1)
fees. The Government Bond and Tax Free Funds offer Class T shares at net asset
value plus an initial sales charge. Class T shares do not impose any
distribution and service (12b-1) fees.
    
 
   
The Government Bond and Tax Free Funds offer five other classes through separate
prospectuses: (1) Class A "front-end load" shares; (2) Class B "back-end load"
shares; (3) Class C "level load" shares; (4) Class Y "institutional" shares; and
(5) Class J "network" shares offered through certain financial intermediaries
that have distribution agreements with SM&R. Class A, Class B, Class C, Class Y,
and Class J shares are subject to different sales charges and other expenses
and, accordingly, may have expense ratios and performance that differs from
those of Class T shares. You are encouraged to consider all of the Company's
class alternatives and choose the one that fits your individual circumstances at
the lowest level of fees. FOR MORE INFORMATION ON THE OTHER CLASSES OF SHARES OR
TO REQUEST A PROSPECTUS FOR ANOTHER CLASS, INVESTORS MAY CONTACT INVESTOR
SERVICES AT (800) 231-4639.
    
 
   
ELIGIBLE PURCHASERS OF CLASS T SHARES

    asset value agreement with SM&R; and
    
 
   
(k) registered representatives and employees of securities dealers with whom
    SM&R has a selling agreement.
    
 
   
YOU HAVE THE SOLE RESPONSIBILITY OF NOTIFYING SM&R THAT YOU INTEND TO QUALIFY
UNDER ONE OF THESE CATEGORIES.
    
 
   
OPENING AN ACCOUNT. Your ability to open a new account depends on the basis of
your eligibility to purchase Class T shares, as follows:
    
 
   
  - If you are eligible to purchase Class T shares because you are an existing
    shareholder of either the Government Bond Fund or the
    
 
                                       19
<PAGE>
   
    Tax Free Fund (and owned shares on December 31, 1998), you can purchase
    additional Class T shares of the fund in which you are invested, but cannot
    open a new account in another fund. For example, if you own shares of the
    Government Bond Fund only (and you owned shares of that fund on December 31,
    1998), you may purchase additional Class T shares of that fund. However, you
    cannot purchase Class T shares of the Tax Free Fund.
    
 
   
  - If you are a designated person listed in (a)-(k) above, you can open a new
    account in Class T shares and may purchase Class T shares of any fund
    managed by SM&R. YOU ARE ALSO ELIGIBLE FOR WAIVER OF THE INITIAL SALES
    CHARGE AS DESCRIBED BELOW.
    
 
   
CLASS T SALES CHARGES
    
 
   
The offering price of Class T shares is the net asset value plus a "front-end"
sales charge. The sales charge is a percentage of the offering price, as shown
in the following table:

SALES CHARGE REDUCTIONS AND WAIVERS
    
 
   
DISCOUNTS THROUGH CONCURRENT PURCHASES. To qualify for a reduced sales charge on
Class T shares, you may combine concurrent purchases of Class T shares of funds
managed by SM&R. Investors that are eligible to combine concurrent purchases to
qualify for a reduced sales charge include:
    
 
   
(1) Any individual;
    
 
   
(2) Any individual, his or her spouse, and trusts or custodial accounts for
    their minor children;
    
 
   
(3) A trustee or fiduciary of a single trust estate or single fiduciary account.
    
 
   
DISCOUNTS THROUGH A RIGHT OF ACCUMULATION. If you already own Class A or Class T
shares of a fund managed by SM&R, you may be able to receive a discount when you
buy additional shares. The
    
 
                                       20
<PAGE>
   
amount you paid for the shares you already own may be "accumulated"--I.E.,
combined together with the offering price of the new shares you plan to buy--to
achieve quantities eligible for discount.
    
 
   
LETTER OF INTENT. You may qualify for a reduced sales charge on purchases of
Class T shares of funds managed by SM&R by completing the Letter of Intent
section of the account application. Under a Letter of Intent, an investor
expresses an intention to purchase, within 13 months of the initial investment,
a specified amount of Class T shares of funds managed by SM&R which, if made
concurrently, would qualify for a reduced sales charge. Upon execution of the
Letter of Intent, the investor must make a minimum initial investment equal to
ten percent (10%) of the amount necessary to qualify for the applicable reduced
sales charge. To assure that the full applicable sales charge will be paid if
the intended purchase is not completed, five percent (5%) of the total intended
purchase amount will be held in escrow in shares registered in the investor's
name. Shares held in escrow under a Letter of Intent are not eligible for the
exchange privilege until the Letter of Intent is completed or canceled. A Letter
of Intent does not represent a binding obligation on the part of the investor to
purchase or the funds to sell the full amount of shares specified.
    
 
   
WAIVER OF INITIAL SALES CHARGE FOR CERTAIN PURCHASERS. After SM&R receives a
written request, those designated person listed in (a)-(k) above may purchase
Class T shares of the Government Bond Fund and the Tax Free Fund at net asset
value per share without the imposition of any sales charge.

INVESTMENT OBJECTIVES AND POLICIES
    
- -------------------------------------------------------------------
 
   
Each fund pursues its own investment objective through various investment
policies and techniques. ONLY THE PRINCIPAL INVESTMENT STRATEGIES OF EACH FUND
AND THE PRINCIPAL TYPES OF SECURITIES EACH FUND PLANS TO PURCHASE ARE DESCRIBED
BELOW. These policies and techniques are not fundamental and may be changed by
the Board of Directors without shareholder approval.
    
 
   
Because of the market risks inherent in any investment, the funds may not
achieve their investment objectives. In addition, effective management of each
fund is subject to general economic conditions and to the ability and investment
techniques of management. The net asset value of each fund's shares will vary
and the redemption value of shares may be either higher or lower than the
shareholder's cost. Since each fund has a different investment objective, each
will have different investment results and incur different market, financial,
and other risks.
    
 
   
GOVERNMENT BOND FUND
(FORMERLY NAMED AMERICAN NATIONAL GOVERNMENT INCOME FUND SERIES)
    
 
   
The Government Bond Fund seeks to achieve its objective through investment of
65% or more of its total assets in securities issued or guaranteed by the U.S.
Government, its agencies or instrumentalities ("U.S. Government Obligations")
which include, but are not limited to, U.S. Treasury Bonds, Notes and Bills and
securities issued by instrumentalities of the U.S. Government.
    
 
   
U.S. GOVERNMENT OBLIGATIONS--There are two broad categories of U.S. Government
Obligations:
    
 
   
(1) direct obligations of the U.S. Treasury, and
    
 
   
(2) obligations issued or guaranteed by agencies or instrumentalities of the
    U.S. Government.
    
 
   
Some obligations issued or guaranteed by agencies or instrumentalities of the
U.S. Government are backed by the full faith and credit of the United States
(such as Government National Mortgage Association Certificates); others, by the
agency or instrumentality with limited rights of the issuer to borrow from the
U.S. Treasury (such as Federal National Mortgage Association Bonds); and others,
only by the credit of the issuer. No assurance can be given that the U.S.
    
 
                                       22
<PAGE>
   
Government would lend money to or otherwise provide financial support to U.S.
Government sponsored instrumentalities; it is not obligated by law to do so.
    
 
   
MORTGAGE-BACKED SECURITIES--We anticipate that a substantial portion of the
Government Bond Fund's portfolio will consist of mortgage-backed securities
issued or guaranteed by the U.S. Government, its agencies, or instrumentalities.
These securities represent part ownership of pools of mortgage loans secured by
real property, such as certificates issued by the Government National Mortgage
Association ("GNMA" or "Ginnie Mae"), the Federal National Mortgage Association
("FNMA" or "Fannie Mae"), and the Federal Home Loan Mortgage Corporation
("FHLMC" or "Freddie Mac"). Mortgage-backed securities also include mortgage
pass-through certificates representing participation interests in pools of
mortgage loans originated by the U.S. Government and guaranteed by U.S.
Government agencies such as GNMA, FNMA, or FHLMC. Such certificates, which are
ownership interests in the underlying mortgage loans, differ from conventional
debt securities which provide for periodic payment of interest in fixed amounts
and principal payments at maturity or on specified dates. With pass-through
certificates, both principal and interest payments, including prepayments, are
passed through to the holder of the certificate and provide for monthly payments
of interest and principal. GNMA, a federal agency, issues pass-through
certificates that are guaranteed as to timely payment of principal and interest.
FNMA, a federally chartered and privately owned corporation, issues mortgage
pass-through securities and guarantees them as to timely payment of principal
and interest. FHLMC, a corporate instrumentality of the United States, issues
participation certificates that represent an interest in mortgages from FHLMC's
portfolio. FHLMC guarantees the timely payment of interest and the ultimate
collection of principal. FNMA and FHLMC are not backed by the full faith and
credit of the United States, although FNMA and FHLMC are authorized to borrow
from the U.S. Treasury to meet their obligations. Those mentioned are but a few
of the mortgage-backed securities currently available. The Government Bond Fund
will not purchase interest-only or principal-only mortgage-backed securities.
    
 
   
The yield characteristics of mortgage-backed securities differ from traditional
debt securities. Among the major differences are that interest and principal
payments are made more frequently, usually
    
 
                                       23
<PAGE>
   
monthly, and that principal may be prepaid at any time because the underlying
mortgage loans generally may be prepaid at any time. The average mortgage in a
pool may be expected to be repaid within about twelve (12) years. If mortgage
interest rates decrease, the value of the Government Bond Fund's securities will
generally increase. However, we anticipate that the average life of the
mortgages in the pool will decrease as borrowers refinance and prepay mortgages
to take advantage of lower interest rates. The Government Bond Fund invests the
proceeds from such prepayments at the then prevailing lower interest rates. On
the other hand, if interest rates increase, the value of the Fund's securities
generally will decrease while it is anticipated that borrowers will not
refinance and, therefore, the average life of the mortgages in the pool will be
longer. In addition, if the Government Bond Fund purchases such a security at a
premium, a prepayment rate faster than expected will reduce yield to maturity,
while a prepayment rate slower than expected will have the opposite effect of
increasing yield to maturity. Conversely, if the Government Bond Fund purchases
these securities at a discount, faster than expected prepayments will increase
yield to maturity, while slower than expected prepayments will reduce yield to
maturity.
    
 
   
COLLATERALIZED MORTGAGE OBLIGATIONS--The Government Bond Fund may invest a
portion of its assets in collateralized mortgage obligations or "CMOs," which
are debt obligations collateralized by a portfolio or pool of mortgages,
mortgage-backed securities, or U.S. Government securities. Collateralized
obligations in which the Government Bond Fund may invest are issued or
guaranteed by a U.S. Government agency or instrumentality, such as the FHLMC. A
variety of types of collateralized obligations are currently available and
others may become available in the future. One should keep in mind that during
periods of rapid interest rate fluctuation, the price of a security, such as a
CMO, could either increase or decrease based on inherent interest rate risk.
Additionally, the risk of maturities shortening or lengthening in conjunction
with interest rate movement, could magnify the overall effect of the price
fluctuation.
    
 
   
A CMO is often issued in multiple classes with varying maturities and interest
rates. As a result the investor may obtain greater predictability of maturity
than with direct investments in mortgage-backed securities. Thus, classes with
shorter maturities may have lower volatility and lower yield while those with
longer maturities
    
 
                                       24
<PAGE>
   
may have higher volatility and higher yields. This provides the investor with
greater control over the characteristics of the investment in a changing
interest rate environment. A more complete description of CMOs is contained in
the Statement of Additional Information.
    
 
   
The Government Bond Fund may also invest in parallel pay CMOs and Planned
Amortization Class CMOs ("PAC Bonds"). Parallel pay CMOs are structured to
provide payments of principal on each payment date to more than one class. PAC
Bonds generally require payments of a specified amount of principal on each
payment date. PAC Bonds are always parallel pay CMOs with the required principal
payment on such securities having the highest priority after interest has been
paid to all classes.
    
 
   
The Government Bond Fund may also invest in securities issued by private issuers
that represent an interest in or are secured by mortgage-backed securities
issued or guaranteed by the U.S. government or one of its agencies or
instrumentalities. In addition, the fund may invest in securities issued by
private issuers that represent an interest in or are secured by mortgage loans
or mortgage-backed securities without a government guarantee but usually have
some form of private credit enhancement.
    
 
   
ZERO COUPON BONDS--The Government Bond Fund may invest in zero coupon bonds,
which are debt obligations issued or purchased at a significant discount from
face value. The Government Bond Fund will only purchase zero coupon bonds which
are U.S. Government Obligations. The discount approximates the total amount of
interest the bonds will accrue and compound over the period until maturity or
the first interest payment date at a rate of interest reflecting the market rate
of the security at the time of issuance. Zero coupon bonds do not entitle the
holder to any periodic payments of interest prior to maturity. Its value as an
investment consists of the difference between its face value at the time of
maturity and the price for which it was acquired which is generally an amount
significantly less than face value (sometimes referred to as a "deep discount"
price). Zero coupon bonds require a higher rate of return to attract investors
who are willing to defer receipt of cash. Accordingly, although not providing
current income, SM&R believes that zero coupon bonds can be effectively used to
lock in a higher rate of return in a declining interest environment. Such
investments may experience greater volatility in market value than debt
obligations which make regular
    
 
                                       25

payments of interest. The Fund will accrue income on such investments for tax
and accounting purposes, as required, which is distributable to shareholders and
which, because no cash is received at the time of accrual, may require the
liquidation of other portfolio securities to satisfy the Fund's distribution
obligations.
    
 
   
TAX FREE FUND (FORMERLY NAMED AMERICAN NATIONAL TAX FREE FUND SERIES)
    
 
   
The Tax Free Fund, as a matter of fundamental policy, seeks to achieve its
objective by investing at least 80% of the value of its net assets in municipal
securities the interest on which is exempt from federal income taxes.
    
 
   
The Tax Free Fund has no restrictions on the maturity of municipal securities in
which it may invest. Accordingly, it will seek to invest in municipal securities
of such maturities which, in the judgement of SM&R, the adviser, will provide a
high level of current income consistent with prudent investment, with
consideration given to market conditions.
    
 
   
The Tax Free Fund will invest, without percentage limitations, in municipal
securities having at the time of purchase one of the four highest municipal
ratings by Moody's Investor Service, Inc. ("Moody's"), Standard & Poor's
Corporation ("S&P"), or Fitch Investors Service (E.G., MIG 4 or higher by
Moody's) or in securities which are not rated, provided that, in the opinion of
SM&R, such securities are comparable in quality to those within the four highest
ratings. The rating agencies consider that bonds rated in the fourth highest
category may have some speculative characteristics and that changes in economic
conditions or other circumstances are more likely to lead to a weakened capacity
to make principal and interest payments on those bonds than is the case with
higher grade bonds. SM&R will only purchase bonds rated in such fourth category
if it believes that the purchase of such bonds is consistent with the Tax Free
Fund's investment objective. In the event the rating of an issue held by the Tax
Free Fund is changed by the rating service, such change will be considered by
the Tax Free Fund in its evaluation of the overall investment merits of that
security but such change will not necessarily result in an automatic sale of the
security. Any security held which is subsequently downgraded below BBB by S&P or
Baa by Moody's will be sold as soon as it is advantageous to do so
    
 
                                       26
<PAGE>
   
after the downgrade. A description of the ratings may be found in the Appendix
to this Prospectus.
    
 
   
Purchasing unrated municipal securities, which may be less liquid than
comparably rated municipal securities, involves somewhat greater risk and
consequently the Tax Free Fund may not invest more than 20% of its net assets in
unrated municipal securities. To attempt to minimize the risk of such
investments, SM&R will, prior to acquiring unrated securities, consider the
terms of the offering and various other factors to determine the issuer's
comparative credit rating and whether the securities are consistent with the Tax
Free Fund's investment objective and policies.
    
 
   
During normal market conditions, the Tax Free Fund will have at least 80% of its
net assets invested in municipal securities the income of which is fully exempt
from federal income taxation. Furthermore, under normal market conditions up to
20% of the Tax Free Fund's net assets, and as a temporary defensive measure
during abnormal market conditions, up to 50% of its net assets may be invested
in the following types of taxable fixed income obligations:
    
 
   
(1) obligations issued or guaranteed by the U.S. government, its agencies,
    instrumentalities or authorities (See "Government Bond Fund" above for an
    explanation of U.S. government obligations);
    
 
   
(2) corporate debt securities which at the date of the investment are rated A or
    higher by Moody's or by S&P;
    
 
   
(3) commercial paper which at the date of the investment is rated in one of the
    two top categories by Moody's or by S&P or if not rated, is issued by a
    company which at the date of the investment has an outstanding debt issue
    rated A or higher by Moody's or A or higher by S&P;
    
 
   
(4) certificates of deposit issued by U.S. banks which at the date of the
    investment have capital surplus and undivided profits of $1 billion as of
    the date of their most recently published financial statements; and
    
 
   
(5) repurchase agreements secured by U.S. government securities, provided that
    no more than 15% of the Fund's net assets will be invested in illiquid
    securities including repurchase agreements with maturities in excess of
    seven days.
    
 
                                       27
<PAGE>
   
To the extent income dividends include income from taxable sources, a portion of
a shareholder's dividend income may be taxable. (See "Dividends, Distributions,
and Taxes"). In addition, Congress could enact tax legislation such as a flat
tax rate that would make tax-free bonds less desirable to investors seeking ways
to reduce taxable income. If that were to occur, it could cause the value of the
securities to drop.
    
 
   
The Tax Free Fund's ability to achieve its objective depends partially on the
prompt payment by issuers of the interest on and principal of the municipal
securities held. A moratorium, default, or other non-payment of interest or
principal when due could, in addition to affecting the market value and
liquidity of the particular security, affect the market value and liquidity of
other municipal securities. Additionally, the market for municipal securities is
often thin and can be temporarily affected by large purchases and sales. As a
result, the Tax Free Fund will attempt to minimize risk by diversifying its
investments by investing no more than 5% of its net assets in the securities of
any one issuer (this limitation does not apply to investments issued or
guaranteed by the U.S. Government or its instrumentalities) and by investing no
more than 25% of its net assets in municipal securities issued in any one state
or territory. Each political subdivision, agency, instrumentality, and each
multi-state agency of which a state is a member will be regarded as a separate
issuer for the purpose of determining diversification.
    
 
   
MUNICIPAL SECURITIES--The term "municipal securities," as used in this
Prospectus means obligations issued by or on behalf of states, territories, and
possessions of the U.S. and the District of Columbia and their political
subdivisions, agencies, and instrumentalities, the interest on which is exempt
from federal income tax. An opinion as to the tax-exempt status of a municipal
security generally is rendered to the issuer by the issuer's counsel at the time
of issuance of the security. Neither the funds nor SM&R will review the
proceedings relating to the issuance of municipal obligations or the basis for
opinions of counsel.
    
 
   
Municipal securities are used to raise money for various public purposes such as
constructing public facilities and making loans to public institutions. Certain
types of municipal bonds are issued to obtain funding for privately operated
facilities. Further information on the maturity and funding classifications of
municipal securities is included in the Statement of Additional Information.
    
 
                                       28
<PAGE>
   
Yields on municipal securities vary, depending on a variety of factors,
including the general condition of the financial markets and of the municipal
securities market, the size of a particular offering, the maturity of the
obligation and the credit rating of the issuer. Like other interest-bearing
securities, the value of municipal securities changes as interest rates
fluctuate. For example, if interest rates increase from the time a security is
purchased, the security's value and sales price generally will be less than its
purchase cost. Conversely, if interest rates decline from the time a security is
purchased, the security's value and sales price may be greater than its purchase
cost. Generally, municipal securities of longer maturities produce higher
current yields than municipal securities with shorter maturities but are subject
to greater price fluctuation due to changes in interest rates, tax laws and
other general market factors. Lower-rated municipal securities generally produce
a higher yield with shorter maturities than higher-rated municipal securities
due to the perception of a greater degree of risk as to the ability of the
issuer to pay principal and interest.
    
 
   
The Tax Free Fund may purchase municipal bonds for which the payments of
principal and interest are secured by an escrow account of securities backed by
the full faith and credit of the U.S. government ("defeased") and municipal
securities whose principal and interest payments are insured by a commercial
insurance company as long as the underlying credit is investment grade (BBB or
better by S&P and Fitch and Baa or better by Moody's) ("insured"). The Tax Free
Fund may also purchase unrated securities of issuers which SM&R believes would
have been rated BBB or Baa had the issuer requested a rating from S&P, Fitch or
Moody's. Such implied investment grade rating will be determined by SM&R upon
its performance of a credit analysis of the issue and the issuer. Such credit
analysis may consist of a review of such items as the issuer's debt
characteristics, financial information, structure of the issue, liquidity of the
issue, quality of the issuer, current economic climate, financial adviser, and
underwriter. Insured and defeased bonds are further described in the Statement
of Additional Information. In general, these types of municipal securities will
not be treated as an obligation of the original municipality for purposes of
determining industry concentration.

PRIMARY FUND (FORMERLY NAMED AMERICAN NATIONAL PRIMARY FUND SERIES)
    
 
   
Commercial paper is short-term unsecured promissory notes issued by corporations
to finance short-term credit needs. Commercial paper is usually sold on a
discount basis and has a maturity at the time of issuance not exceeding nine
months. The Primary Fund will invest only in commercial paper which, at the date
of such investment, is rated in one of the two top categories by one or more of
the nationally recognized statistical rating organizations ("NRSROs") (See the
"Appendix" hereto for information about such ratings and such rating
organizations).
    
 
   
The Primary Fund, consistent with its investment objective, will attempt to
maximize yield by trying to take advantage of changing conditions and trends. It
may also attempt to take advantage of what are believed to be disparities in
yield relationships between different instruments. This procedure may increase
or decrease the portfolio yield depending upon the Primary Fund's ability to
correctly time and execute such transactions. Although the Primary Fund's assets
will be invested in securities with short maturities, the Primary Fund will
manage its portfolio as described above. (See "Portfolio Transactions and
Brokerage Allocation" in the Statement of Additional Information.)
    
 
   
OTHER INVESTMENTS--The Primary Fund may invest in (i) U.S. Government
Obligations (See the "Government Bond Fund" above for an explanation of U.S.
Government Obligations); (ii) other corporate obligations, such as bonds,
debentures or notes maturing in five (5) years or less at the time of purchase
which at the date of the investment are rated "A" or higher by an NRSRO; and
(iii) negotiable certificates of deposit of banks (including U.S. dollar
denominated obligations of foreign branches of U.S. banks and U.S. branches of
foreign banks and savings and loan associations and banker's acceptances of U.S.
banks which banks and savings and loan associations have total assets at the
date of investment (as of the date of their most recent published financial
statements) of at least $1 billion (See "INVESTMENT OBJECTIVES AND
POLICIES--Certificates of Deposit" in the Statement of Additional Information
for a description of the securities) and (iv) repurchase agreements with respect
to any type of instrument in which the Primary Fund is authorized to invest even
though the underlying instrument may mature in more than two (2) years.

MONEY MARKET FUND
    
 
   
The Money Market Fund seeks to achieve its objective by investing in short-term
money market instruments determined to be of high quality by SM&R pursuant to
guidelines established by the Company's Board of Directors. The Money Market
Fund may invest in the following types of high quality debt obligations:
    
 
   
(1) U.S. GOVERNMENT OBLIGATIONS. U.S. Government Obligations consist of
marketable securities issued or guaranteed as to both principal and interest by
the United States Government or by its agencies and instrumentalities. (See
"Government Bond Fund" above for an explanation of U.S. Government Obligations).
    
 
   
(2) CERTIFICATES OF DEPOSIT. Certificates of deposit are negotiable certificates
issued against funds deposited in a commercial bank for a definite period of
time and earning a specified return. The Money Market Fund will invest only in
certificates of deposit of U.S. banks that have total assets in excess of $1
billion at the time of investment.
    
 
   
(3) BANKER'S ACCEPTANCES. Banker's acceptances are short-term instruments issued
by banks, generally for the purpose of financing imports or exports. An
acceptance is a time draft drawn on a bank by the importer or exporter to obtain
a stated amount of funds to pay for specific merchandise. The draft is then
"accepted" and is an irrevocable obligation of the issuing bank.
    
 
   
(4) COMMERCIAL PAPER. As discussed above under "Primary Fund," commercial paper
is short-term unsecured promissory notes issued by corporations to finance
short-term credit needs.
    
 
   
(5) BONDS AND NOTES. The Money Market Fund may invest in corporate bonds or
notes with a remaining maturity of one year or less.
    
 
   
(6) COLLATERALIZED MORTGAGE OBLIGATIONS. As discussed above under "Government
Bond Fund," CMOs are debt obligations collateralized by a portfolio or pool of
mortgages, mortgage-backed securities, or U.S. Government securities.
    
 
   
The Money Market Fund does not currently intend to invest in unrated securities,
securities subject to demand features, floating rate instruments, securities
subject to guarantees, and variable rate instruments.
    
 
                                       31
<PAGE>
   
The Money Market Fund limits its investments to those short-term securities that
the Board determines present minimal credit risk and that are "Eligible
Securities" when acquired by the Fund. As used in this Prospectus, "Eligible
Securities" means securities that are:
    
 
   
(a) rated in one of the two highest short-term rating categories, or
    
 
   
(b) whose issuer has another class of debt obligations rated in one of the two
    highest short-term rating categories.
    
 
   
To rely on a rating assigned to other debt obligations, those obligations must
be of comparable priority and security. All ratings must have been issued by the
requisite NRSROs. Currently, five organizations are NRSROs: Moody's, S&P, Fitch
Investors Service, Inc., Duff and Phelps, Inc., and Thomson BankWatch, Inc. A
discussion of the ratings categories of S&P and Moody's is contained in the
Appendix.
    
 
   
The Money Market Fund generally limits its investments in securities, as
follows:
    
 
   
  - It will not invest in securities issued by any one issuer, other than the
    U.S. Government, its agencies, or instrumentalities, in an amount that
    exceeds 5% of its total assets.
    
 
   
  - It will not invest more than 5% of its total assets in securities relying on
    ratings in the second highest rating category.
    
 
   
  - It will not invest more than 1% of its total assets in securities of any one
    issuer that rely on ratings in the second highest rating category.
    
 
   
(See "Investment Objectives and Policies" in the Statement of Additional
Information for a more detailed explanation of the investment categories.) The
Fund will maintain a dollar-weighted average portfolio maturity of 90 days or
less, and will not invest in any security with a remaining maturity of over 397
days (13 months).
    
 
   
Investments in money market instruments are subject to the ability of the issuer
to make payment at maturity. In addition, the Money Market Fund's performance
will vary depending on changes in short-term interest rates. However, both the
financial and market risks of investment in the Money Market Fund may be
expected to be less than for any other Fund. By limiting its investments to
Eligible Securities, the Money Market Fund may not achieve as high a level of
current income as a fund investing in lower-rated securities.

RISK FACTORS
    
- -------------------------------------------------------------------
 
   
The following discussion relates to all four funds. The risk/return summary
located at the beginning of this prospectus identifies some specific risks
applicable to each individual fund.
    
 
   
GENERAL. There is no assurance that a fund will achieve its goals. Generally, if
the securities owned by a fund increase in value, the value of the shares of the
fund which you own will increase. Similarly, if the securities owned by a fund
decrease in value, the value of your shares will also go down. In this way, you
participate in any change in the value of the securities owned by a fund.
    
 
   
The risk inherent in investing in any fund is a risk common to any security.
That is, the value of a fund's shares will fluctuate in response to changes in
economic conditions, interest rates and the market's perception of the
underlying portfolio securities held by that fund. Each fund's share value
depends on general economic and securities market conditions, the investment
decisions of its management, and numerous other factors. All of these factors
are inherently uncertain and, in some cases, unforeseeable.
    
 
   
Any of the funds could lose money if the stock markets in general go down or if
the particular debt obligations purchased by a fund go down in value. In
addition, the funds could lose money if prevailing interest rates increase or if
the debt securities purchased by a fund are downgraded or defaulted upon.
    
 
   
DEBT SECURITIES RISKS. Debt securities are subject to change in their values due
to changes in prevailing interest rates. The magnitude of these fluctuations
will often be greater for longer-term debt securities than shorter-term debt
securities. When prevailing interest rates fall, the values of already-issued
debt securities generally rise. Accordingly, if interest rates go down after a
security is purchased, such security might be valued and/or sold at a price
greater than its cost. If interest rates were to drop dramatically, some of the
securities could be called and/or prepaid, requiring reinvesting in securities
at much lower yields.
    
 
   
On the other hand, when prevailing interest rates rise, the values of
already-issued debt securities generally fall. Accordingly, if interest rates
increase after a security is purchased, such security might be valued and/or
sold at a price less than its cost. In such circumstances,
    
 
                                       33
<PAGE>
   
the value of existing bonds decrease because the interest payments from existing
bonds are less attractive than new issues with higher interest rates and
investors would lose money if they liquidate holdings.
    
 
   
The funds could lose money if any bonds they own are downgraded in credit rating
or go into default. A moratorium, default, or other non-payment of interest or
principal when due could, in addition to affecting the market value and
liquidity of the particular security, affect the market value and liquidity of
other securities. A change in credit rating of an issuer can also affect the
bond's value, thus affecting the market value of the funds. However, the funds
invest predominately in investment grade bonds in order to minimize credit risk.
(See "Investment Objectives and Policies" for more information about the ratings
required for investments by each specific fund.) Moreover, substantial
redemptions of fund shares could require a fund to sell portfolio securities at
a time when a sale might not be favorable.
    
 
   
U.S. GOVERNMENT OBLIGATIONS. Investments in U.S. Government Obligations are not
all backed by the "full faith and credit" of the United States Government. Some
are backed only by the rights of the issuer to borrow from the U.S. Treasury and
others are supported only by the credit of the issuing instrumentality. No
assurance can be given that the U.S. Government would lend money to or otherwise
provide financial support to U.S. Government sponsored instrumentalities.
    
 
   
MARKET RISKS. Because the funds may invest in debt obligations which are traded
on securities exchanges, the value of each fund's portfolio will be affected by
changes in the stock markets. At times, the stock markets can be volatile and
stock prices can change substantially. This market risk will affect each fund's
net asset value per share, which will fluctuate as the values of each fund's
portfolio securities change. Prices do not always change uniformly or at the
same time and the various stock markets do not always move in the same direction
at the same time. Other factors specific to a particular company also affect the
price of that company's debt obligations (for example, poor earnings, loss of
major customers, or major litigation). The funds cannot always predict the
factors that will affect a security's price. The funds, however, do attempt to
limit market risk by diversifying their investments. The funds diversify their
investments by generally investing only a small percentage of their assets in
the debt
    
 
                                       34
<PAGE>
   
obligations of any one company and by not holding a substantial amount of the
debt obligations of any one company.
    
 
   
REPURCHASE AGREEMENTS. In a repurchase agreement, a fund buys a security and
simultaneously sells it to the vendor for delivery at a future date. These
agreements are used primarily for cash purposes. A fund entering into a
repurchase agreement may lose money if the other party to the transaction fails
to pay the resale price on the delivery date. Such a default may delay or
prevent the fund from disposing of the underlying securities. The value of the
underlying securities may go down during the period in which the fund seeks to
dispose of them. Also, the fund may incur expenses while trying to sell the
underlying securities. Finally, the fund risks losing all or a part of the
income from the agreement.
    
 
   
OTHER RISKS. Each investor will be subject to all the risks normally attendant
to business operations, changes in general economic conditions, governmental
rules and fiscal policies, acts of God, and other factors beyond the control of
the funds' management.
    
 
   
YEAR 2000 RISKS. Many services provided to the funds and their shareholders
depend on the smooth functioning of computer systems. Many computer software
systems in use today cannot distinguish the year 2000 from the year 1900 because
of the way dates are encoded and calculated, referred to as the "Year 2000
Problem." The Year 2000 Problem could have a negative impact on handling
securities trades, payment of interest and dividends, pricing, and account
services. Like other mutual funds, financial and business organizations, and
individuals around the world, the funds could be adversely affected if the
computer systems used by SM&R (which acts as their investment adviser,
underwriter, custodian, and transfer agent) do not properly process and
calculate date-related information and data from and after January 1, 2000. SM&R
is taking steps to address the Year 2000 Problem with respect to the computer
systems that it uses and to obtain assurances that comparable steps are being
taken by any other service providers. At this time, however, there can be no
assurance that these steps will be sufficient to avoid any adverse impact on the
funds and their shareholders.
    
 
   
PURCHASES AND REDEMPTIONS
    
- -------------------------------------------------------------------
 
                                       35
<PAGE>
   
PURCHASING SHARES
    
 
   
You may purchase shares of a fund from registered representatives of SM&R, from
authorized broker-dealers, or directly from SM&R. WE RESTRICT PURCHASES OF CLASS
T SHARES. FOR MORE INFORMATION ABOUT THESE RESTRICTIONS, SEE "ELIGIBLE
PURCHASERS OF CLASS T SHARES" UNDER "SHARES OF THE FUNDS."
    
 
   
Such purchases will be at the offering price for such shares determined as and
when provided below (See "Pricing of Fund Shares"). SM&R will send you a monthly
confirmation for any month in which your account is active. You should carefully
review the monthly confirmation and promptly report any discrepancies to SM&R.
You may make initial and subsequent purchases directly through SM&R at the
following address:
    
 
   
    Securities Management and Research, Inc.
    2450 South Shore Boulevard, Suite 400
    League City, Texas 77573
    
 
   
Certificates are not normally issued for shares of the funds in an effort to
minimize the risk of loss or theft. SM&R confirms investors' purchases and
credits such purchases to their accounts on the books maintained by SM&R.
Investors have the same rights of share ownership as they would if certificates
had been issued. Furthermore, a lost, stolen or destroyed certificate cannot be
replaced without obtaining a sufficient indemnity bond. The cost of such a bond
is borne by the investor and can be 2% or more of the value of the lost, stolen
or destroyed certificate.
    
 
   
OPENING AN ACCOUNT: To purchase shares, you must submit an account application
which includes the purchaser suitability form. If you would like to take
advantage of the electronic services available, please complete the electronic
transfer options section of the account application. Special forms are required
when establishing an IRA/ SEP or 403(b) plan. Please call Investor Services at
(800) 231-4639 and request special forms when establishing retirement plans.
    
 
   
MINIMUM PURCHASE REQUIREMENT: For Class T shares of the Government Bond and Tax
Free Funds, your initial investment must be at least $100 and all subsequent
investments must be at least $20. For the Primary and the Money Market Fund,
your initial investment must be at least $1000 and all subsequent investments
must be at least $100. We waive these initial investment minimums when
    
 
                                       36
<PAGE>
   
purchases are part of certain systematic investment programs (See "Special
Purchase Plans and Services" for additional information on reduction of the
minimums). We reserve the right to reject any purchase.
    
 
   
PURCHASES BY MAIL: Make your check(s) payable to SM&R and send the check(s) to
the address indicated above. Please note that third party checks will not be
accepted to open a new account, except for IRA rollover checks that are properly
endorsed. If you make subsequent investments by mail, you must indicate your
name, account number, and the name of the class and the fund being purchased.
You may use the remittance slip attached to the confirmation statement.
    
 
   
PURCHASES BY WIRE: TO ENSURE PROPER CREDITING OF A WIRE INVESTMENT, YOU MUST
HAVE AN EXECUTED ACCOUNT APPLICATION AND PURCHASER SUITABILITY FORM ON FILE WITH
THE TRANSFER AGENT. You may then wire your investment to The Moody National Bank
of Galveston ("Moody National Bank") by providing the following instructions to
your bank:
    
 
   
    The Moody National Bank of Galveston ABA #113100091
    Securities Management and Research, Inc. #035 868 9
    Name of Class and Fund (E.G., Class T of the Government Bond Fund)
    Fund Account Number (number appears on your confirmation statement)
    Your Name (E.G., Mary Smith)
    
 
   
PURCHASES BY EXCHANGE: Call Investor Services if you have established telephone
exchange privileges on your account. See "Special Purchase Plans and
Services--Exchange Privilege" for procedures and additional information relating
to telephone exchanges. For limitations on exchanges, see "Excessive Trading"
also under "Special Purchase Plans and Services."
    
 
   
PRICING OF FUND SHARES
    
 
   
GENERAL (HOW SHARES ARE PRICED). We determine each fund's offering price once
each business day. The offering price equals a fund's net asset value plus the
sales charge, if any, computed at the rate set forth in the applicable table for
the class. (See "Shares of the Funds--Sales Charges.") You may purchase shares
of the Primary
    
 
                                       37
<PAGE>
   
and Money Market Funds without a sales charge. Accordingly, the offering price
for shares of those funds is net asset value.
    
 
   
EFFECTIVE DATE OF PURCHASES AND REDEMPTIONS (WHEN SHARES ARE PRICED).
Calculation of net asset value is made once each business day at the close of
the New York Stock Exchange (currently 3:00 p.m. Central Time). Accordingly, the
price you pay or receive for shares of a fund depends, in part, on the day and
time you make your purchase or redemption. On any business day, we will execute
purchases and redemptions at the applicable price determined that day if:
    
 
   
  - SM&R receives your order in proper form prior to the close of the Exchange;
    
 
   
  - a securities dealer having a dealer contract with SM&R receives your order
    prior to the close of the Exchange and reports your order to SM&R prior to
    SM&R's close of business (currently 4:30 p.m. Central Time) on the same day;
    or

If we receive your order after the close of the Exchange, on customary national
business holidays, or on an SM&R business holiday, we will execute your purchase
or redemption at the price determined on the next business day. In unusual

allowed by federal securities laws.

SPECIAL PURCHASE PLANS AND SERVICES
    
 
   
In addition to the special plans described above that permit you to reduce the
initial sales charge assessed on Class T shares, the Company offers other
services and plans that are designed to facilitate investment in the funds. At
this time, there is no charge to you for these services. The Company may impose
fees for such services in the future. Be aware, however, that if you elect to
participate in the ACH plan described below, you should check with your
financial institution for any additional charges imposed for this service. For
additional information contact your registered representative or SM&R. A
shareholder considering any of the plans or services described below should
consult a tax advisor before beginning a plan.
    
 
   
ELECTRONIC TRANSFERS (ACH). The electronic transfer option allows you to move
money between your account(s) and your bank, savings and loan, or credit union
account using the Automated Clearing House ("ACH") network. To arrange for
electronic transfers, complete the relevant section of the account application
at the time you open your account and specify the type of service or services
desired. Attach a voided, pre-printed check or deposit slip from your checking,
savings and loan, or credit union account. PASSBOOK SAVINGS ACCOUNTS ARE NOT
ELIGIBLE FOR THE ELECTRONIC TRANSFER OPTION. ADDITIONALLY, YOUR BANK MUST BE A
MEMBER OF THE AUTOMATED CLEARING HOUSE (ACH) NETWORK FOR YOU TO TAKE ADVANTAGE
OF THIS SERVICE. You will receive a confirmation verifying initialization of the
electronic transfer option and may begin conducting transactions in your
account(s) under this option approximately 20 calendar days after receipt of the
verification notice from SM&R. If you elect this option after your account is
established, it may be necessary for you to obtain a signature guarantee for all
individuals named on the account(s).
    
 
   
TELEPHONE SERVICES. You can take advantage of this service by completing the
appropriate sections of the account application when opening your account.
Through this service, you will be able to purchase by ACH, redeem and exchange
shares on those accounts for which you have an executed account application on
file, and have received written verification from SM&R that the service has been
initialized as explained under Electronic Transfers above. If this
    
 
                                       39
<PAGE>
   
option is elected after your account is established, it may be necessary for you
to obtain a signature guarantee for all individuals named on the account(s). We
permit transfers by telephone from a joint account only to another joint account
registered in the identical names. There may be additional restrictions on
telephone transactions by joint account owners. Contact your registered
representative for more information. PLEASE NOTE THAT THE TELEPHONE REDEMPTION
OPTION IS NOT AVAILABLE TO RETIREMENT PLANS.
    
 
   
The funds have implemented the following security procedures intended to protect
your account from losses resulting from unauthorized or fraudulent telephone
instructions: The caller must know:
    
 
   
 (i) the name of the fund or funds;
    
   
 (ii) all digits of the account number;
    
   
(iii) the exact name and address used in the registration(s); and
    
   
 (iv) the Social Security or Employer Identification Number listed on the
      account(s).
    
 
   
Additionally, we record all telephone transactions for your protection.
    
 
   
Neither the funds nor SM&R will be responsible for the authenticity of
transaction instructions received by telephone which comply with the current
security procedures and other requirements. SM&R believes that such security
procedures and other requirements are reasonable and, if followed, you should
bear the risk of any losses resulting from unauthorized or fraudulent telephone
transactions on your account(s).
    
 
   
AUTOMATIC INVESTMENT PLAN. Through this plan, a specified amount is
electronically transferred (via ACH) from your bank account and invested
monthly, bi-monthly, quarterly, or annually into the designated fund(s) at the
applicable offering price determined on the date of the electronic transfer.
    
 
   
WEALTH ACCUMULATION ACCOUNT. Shareholders having account balances of at least
$2,500 in the Money Market Fund may open a Wealth Accumulation Account, which
will provide them with an automatic dollar cost averaging plan. Automatic
monthly purchases of the shares of other funds managed by SM&R may be made by
exchanges from the shareholder's Money Market Fund Wealth Accumulation Account.
Purchases of the other funds must be at least $50 and, unless terminated by the
shareholder, will continue as long as the
    
 
                                       40
<PAGE>
   
balance of the Money Market Fund Wealth Accumulation Account is sufficient.
Additional investments may be made to a Money Market Fund account designated as
a Wealth Accumulation Account to extend the purchase period under the plan.
However, if additional investments are received by SM&R less than ten (10)
business days prior to the 20th of the month, such investments will not be
available for use under the Wealth Accumulation Account until the 20th of the
following month. If the 20th of the month is an SM&R holiday, the purchase will
be processed on the next business day.
    
 
   
Purchases made will be subject to the applicable sales charge of the fund whose
shares are being purchased. Changes in amounts to be purchased, the funds being
purchased, and termination of a Wealth Accumulation Account will be made within
five (5) business days after written instructions are received by SM&R in proper
form (I.E., signed by the owner(s) of record exactly as registered).
    
 
   
Shareholders' rights to make additional investments, to exchange shares, and to
redeem shares in the Money Market Fund and any of the funds managed by SM&R are
not affected by a shareholder's participation in a Wealth Accumulation Account.
However, check writing privileges and expedited redemption by telephone are not
available for the Money Market Fund accounts designated as a part of the Wealth
Accumulation Account.
    
 
   
Primary Fund shareholders that opened a Primary Fund Wealth Accumulation Account
prior to December 31, 1998 will be permitted to continue using the Account
subject to the terms applicable to a Money Market Fund Wealth Accumulation
Account, described above.
    
 
   
EXCHANGE PRIVILEGE. As an investor in a fund, you are permitted to exchange
shares that you own in a fund with shares of another fund managed by SM&R
without the payment of an exchange fee, subject to certain conditions. EXCHANGES
BETWEEN A FUND AND ANOTHER FUND MANAGED BY SM&R ARE AVAILABLE ONLY IN STATES
WHERE THE APPLICABLE FUNDS ARE REGISTERED AND THE EXCHANGE MAY BE LEGALLY MADE.
YOU SHOULD CONTACT SM&R TO DETERMINE WHETHER A FUND IS REGISTERED IN A
PARTICULAR STATE.
    
 
   
GOVERNMENT BOND FUND AND TAX FREE FUND. You may exchange Class T shares that you
own in the Government Bond or Tax Free Fund, without an exchange fee, for
corresponding Class T shares of another fund managed by SM&R. You also may
exchange your
    
 
                                       41
<PAGE>
   
Class T shares for shares of the Primary or Money Market Fund, provided that you
meet any minimum investment requirement for the shares you wish to acquire.
Finally, you may exchange Class T shares of the Government Bond or Tax Free Fund
for shares of another class of the applicable fund, provided that you pay any
difference in sales charges.
    
 
   
PRIMARY FUND AND MONEY MARKET FUND. You may exchange shares you own in the
Primary Fund for shares of the Money Market Fund, and vise versa. You may
exchange shares you own in the Primary or Money Market Fund for shares of a
class of another fund managed by SM&R, provided you pay any sales charge
applicable to the acquired shares.
    
 
   
You may acquire, through an exchange, shares of a class with a contingent
deferred sales charge. If you redeem those shares, the relevant contingent
deferred sales charge, if any, will be calculated from the date that you
initially purchased the original shares, rather than from the date of exchange.
    
 
   
Shares of any fund managed by SM&R held in escrow under a Letter of Intent are
not eligible for the exchange privilege. Such shares will not be released from
escrow until the balance invested during the period specified in the Letter of
Intent equals or exceeds the amount required to be invested under the Letter of
Intent or the shareholder requests, in writing, that the Letter of Intent be
canceled and pays any adjustments in sales charge. After release from escrow,
shares may be exchanged, provided all other applicable conditions are met.
    
 
   
You may request an exchange by telephone or in writing. In order to exchange
shares, the following requirements must be met:
    
 
   
(a) the exchange must be made between accounts having identical registrations
    and addresses;
    
 
   
(b) the shares of the fund acquired through exchange must be qualified for sale
    in the state in which you reside;
    
 
   
(c) the dollar amount of the exchange must meet the minimum investment
    requirement applicable to the shares of the fund that you would acquire
    through the exchange;
    
 
   
(d) SM&R must have received full payment for the shares being exchanged;
    
 
                                       42
<PAGE>
   
(e) your account must have been coded to reflect your certified taxpayer
    identification number, or, if applicable, an appropriate Internal Revenue
    Service Form W-8 (certificate of foreign status) or Form W-9 (certifying
    exempt status);
    
 
   
(f) any shares that you wish to exchange must have been held for at least ten
    (10) business days;
    
 
   
(g) certificates representing shares, if any, are returned before such shares
    are exchanged; and
    
 
   
(h) you have received a prospectus for the shares you receive in the exchange.
    
 
   
The exchange privilege is not an option or right to purchase shares but is
permitted under the respective policies of the participating funds, and may be
modified or discontinued by the participating funds or by SM&R at any time. ANY
GAIN OR LOSS REALIZED ON AN EXCHANGE OR RE-EXCHANGE MAY BE RECOGNIZED FOR
FEDERAL AND STATE INCOME TAX PURPOSES. YOU SHOULD CONSULT YOUR TAX ADVISOR FOR
THE TAX TREATMENT AND EFFECT OF EXCHANGES.
    
 
   
EXCESSIVE TRADING. Frequent trades, involving either substantial fund assets or
a substantial portion of your account or accounts controlled by you, can disrupt
management of the Company and raise the Company's expenses. We currently define
"excessive trading" as exceeding one purchase and sale involving the same fund
within any 120-day period.
    
 
   
For example, you are in Fund X. You can move substantial assets from Fund X to
Fund Y and, within the next 120 days, sell your shares in Fund Y to return to
Fund X or move to Fund Z. If you exceed the number of trades described above,
you may be barred indefinitely from further transactions between the
participating funds.
    
 
   
There are two types of transactions exempted from the excessive trading
guidelines. They are (1) redemptions that are not part of exchanges and (2)
systematic purchases or redemptions.
    
 
   
RETIREMENT PLANS
    
 
   
The following retirement plans may be funded with Class T shares of the
Government Bond Fund, or with shares of the Primary and Money Market Funds:
    
 
                                       43
<PAGE>
   
  - Individual Retirement Accounts (IRAs), which include traditional IRAs, Roth
    IRAs, Education IRAs, and SIMPLE IRAs,
    
 
   
  - Simplified Employee Pension Plans (SEPs),
    
 
   
  - 403(b) Custodial Accounts (TSAs), and
    
 
   
  - corporate retirement plans.
    
 
   
These plans allow you to shelter investment income from federal income tax while
saving for retirement. Information concerning IRAs and TSAs, and the forms
necessary to adopt such plans, can be obtained by contacting your registered
representative or calling SM&R. A regular fund application should be used when
establishing a corporate retirement plan. (See "Purchasing Shares" for the
minimum initial and subsequent purchase requirements.) SM&R acts as trustee or
custodian for IRAs, SEPs, and TSAs for the Company. An annual custodial fee of
$7.50 per account will be charged for any part of a calendar year in which an
investor has an IRA, SEP, or TSA in the Company and will be automatically
deducted from each account. An individual considering a retirement plan may wish
to consult with an attorney or tax adviser.
    
 
   
Because IRAs, SEPs, TSAs, and other qualified plans are exempt from federal
income tax, they will be unable to benefit from the general tax-exempt nature of
the Tax Free Fund. Accordingly, the Tax Free Fund is not generally considered to
be suited for such plans or persons.
    
 
   
DIVIDENDS, DISTRIBUTIONS, AND TAXES
    
 
   
DIVIDENDS.
    
 
   
GOVERNMENT BOND AND TAX FREE FUNDS. The Government Bond and Tax Free Funds will
declare and pay dividends from net investment income monthly and net realized
short-term or long-term capital gains, if any, annually. In order to be entitled
to a dividend, an investor must have acquired shares of a fund prior to the
close of business on the record date. A shareholder should be cautioned,
however, before purchasing shares of a fund immediately prior to a distribution.
Dividends and distributions paid by the funds have the effect of reducing net
asset value per share on the record date by the amount of the payment.
Therefore, a dividend or distribution of record shortly after the purchase of
shares by an investor represents, in substance, a return of capital.
    
 
                                       44
<PAGE>
   
PRIMARY AND MONEY MARKET FUNDS. At 3:00 p.m. Central Time, on each day that the
Exchange is open for trading other than SM&R's business holidays described
above, the Primary and Money Market Funds each will declare a dividend of all of
its net investment income to shareholders of record on that date. Such dividends
will be paid monthly.
    
 
   
DIVIDEND REINVESTMENTS. Dividends and capital gains will be automatically
reinvested at net asset value in additional shares of the fund making such
distribution unless SM&R is instructed otherwise in writing. Distributions not
reinvested are paid by check or transmitted to your bank account through an ACH
transaction, if elected. If the Postal Service cannot deliver your check, or if
your check remains uncashed for six months, the funds reserve the right to
reinvest your distribution check in your account at the net asset value on the
business day of the reinvestment and to reinvest all future distributions in
shares of the applicable fund(s). Dividends and capital gains declared in
December to shareholders of record in December and paid the following January
will be taxable to shareholders as if received in December. This is a convenient
way to accumulate additional shares and maintain or increase the shareholder's
earning base. Of course, any shares so acquired remain at market risk.
    
 
   
Shareholders have the right to change their election with respect to the receipt
of distributions by notifying SM&R in writing, but any such change will be
effective only as to distributions for which the record date is seven or more
business days after SM&R has received the shareholder's written request.
    
 
   
TAXABILITY OF DIVIDENDS. Dividends you receive from the Government Bond,
Primary, and Money Market Funds, whether reinvested or taken as cash, are
generally considered taxable. A fund's long-term capital gains distributions are
taxable as capital gains; dividends from other sources are generally taxable as
ordinary income. Some dividends paid in January may be taxable as if they had
been paid the previous December. The Form 1099 that is mailed to you every
January details your dividends and their federal tax category, although you
should verify your tax liability with your tax professional.
    
 
   
The Tax Free Fund intends to distribute tax-exempt dividends that shareholders
may exclude from their gross income for federal income tax purposes. However,
the Tax Free Fund may invest a portion of its assets in securities that generate
income that is not exempt from
    
 
                                       45
<PAGE>
   
federal or state income tax. Income exempt from federal tax may be subject to
state and local income tax. Any capital gains distributed by the Tax Free Fund
may be taxable. Also, you should also keep in mind that certain income from the
Tax Free Fund may be subject to the federal alternative minimum tax.
    
 
   
BACKUP WITHHOLDING. Backup withholding of federal income tax may be applied at
the rate of 31% from taxable dividends, distributions, and redemption proceeds
(including exchanges) if you fail to furnish the Company with a correct and
properly certified Social Security or Employer Identification Number when you
sign your application, or if you underreport your income to the Internal Revenue
Service.
    
 
   
TAXABILITY OF TRANSACTIONS. Any time you sell or exchange shares, it is
considered a taxable event for you. Depending on the purchase price and the sale
price of the shares you sell or exchange, you may have a gain or a loss on the
transaction. You are responsible for any tax liabilities generated by your
transactions. You should consult with a tax advisor concerning the tax reporting
requirements in effect on the redemption or exchange of such shares.
    
 
   
REDEEMING SHARES
    
 
   
You can redeem fund shares at net asset value determined on the date the request
is received by SM&R in proper form. A redemption request must be addressed to
Securities Management and Research, Inc., 2450 South Shore Boulevard, Suite 400,
League City, Texas 77573.
    
 
   
If uncertain of the redemption requirements, investors should call Investor
Services or write SM&R. Payment will be made as soon as practicable and normally
within seven days after receipt of a redemption request in proper form. We
currently charge a fee in the amount of $8.00 for redemptions by wire under
$5,000.
    
 
   
If the shares being redeemed were purchased by wire, certified check, money
order, or other immediately available funds, redemption proceeds will be mailed
no later than the seventh calendar day following receipt. For shares purchased
by a personal check or ACH transfer, SM&R will process your redemption but will
generally delay sending you the proceeds for up to ten (10) business days to
allow the check or transfer to clear.
    
 
                                       46
<PAGE>
   
TELEPHONE REDEMPTIONS. You may request redemptions by telephone if you have
completed the account application and requested this option. This redemption
feature can only be used if:
    
 
   
(a) the redemption proceeds are to be mailed to the address of record or wired
    to the pre-authorized bank account indicated on the account application;
    
 
   
(b) there has been no change of address of record or pre-authorized bank account
    within the preceding 30 business days;
    
 
   
(c) the shares to be redeemed are not in certificate form;
    
 
   
(d) the security procedures discussed under "Special Purchase Plans And
    Services--Exchange Privilege" have been met; and
    
 
   
(e) the proceeds of the redemption do not exceed $25,000.
    
 
   
SYSTEMATIC WITHDRAWAL PLAN. The Company has a Systematic Withdrawal Plan
("Withdrawal Account"), which permits shareholders having an account value of
$5,000 or more to automatically withdraw a minimum of $50 monthly or each
calendar quarter on or about the 20th of the applicable month. Shareholders
maintaining a Withdrawal Account may elect to have the withdrawal proceeds
automatically deposited in their pre-authorized bank account via an ACH
transaction. This is accomplished by completing the relevant section of the
account application and returning it to SM&R. See "Special Purchase Plans and
Services--Electronic Transfers" for additional information. It may not be
advisable for shareholders to maintain a Withdrawal Account while concurrently
purchasing shares of the Government Bond Fund or the Tax Free Fund because of
the sales charge involved in additional purchases. You should carefully consider
such purchases and contact your financial adviser regarding their advisability.
Dividends and capital gains distributions will automatically be reinvested in
additional shares at net asset value. As with other redemptions, a withdrawal is
a sale for federal income tax purposes. The Systematic Withdrawal Plan will
automatically terminate if all shares are liquidated or withdrawn from the
account. Certificates are not issued for shares held in a Withdrawal Account and
certificates held, if any, must be surrendered when shares are transferred to a
Withdrawal Account. No account covered by a Letter of Intent can be changed to a
Systematic Withdrawal Plan until such time as the Letter of Intent is fulfilled
or terminated, nor
    
 
                                       47
<PAGE>
   
can an account under a Systematic Withdrawal Plan be placed under a Letter of
Intent.
    
 
   
REINVESTMENT PRIVILEGE. Within ninety (90) days of a redemption of Class T
shares of a fund, a shareholder may reinvest all or part of the proceeds in
Class T shares of that same fund at the net asset value next computed after
receipt of the proceeds to be reinvested by SM&R. The shareholder must ask the
transfer agent for this privilege at the time of reinvestment. Prior to
reinvestment of redemption proceeds, a shareholder is encouraged to consult with
his or her accountant or tax advisor to determine any possible tax ramifications
of such a transaction. Each fund managed by SM&R may amend, suspend, or cease
offering this privilege at any time as to shares redeemed after the date of the
amendment, suspension, or cessation.
    
 
   
For further information about the "Systematic Withdrawal Plan" and "Reinvestment
Privilege," contact a registered representative or SM&R.
    
 
   
"PROPER FORM" means the request for redemption must include:
    
 
   
(1) your share certificates, if issued;
    
 
   
(2) your letter of instruction or a stock assignment specifying the fund,
    account number, and number of shares or dollar amount to be redeemed. Both
    share certificates and stock powers, if any, must be endorsed and executed
    exactly as the fund shares are registered. It is suggested that certificates
    be returned by certified mail for your protection;
    
 
   
(3) any required signature guarantees (see "Signature Guarantees" below); and
    
 
   
(4) other supporting legal documents, if required in the case of estates,
    trusts, guardianships, divorce, custodianships, corporations, partnerships,
    pension or profit sharing plans, retirement plans, and other organizations.
    
 
   
Please keep in mind that as a shareholder, it is your responsibility to ensure
that all requests are submitted to the Company's transfer agent in proper form
for processing.
    
 
   
SIGNATURE GUARANTEES. A signature guarantee verifies the authenticity of your
signature. Signature guarantees are required when:
    
 
   
(1) the proceeds of the redemption exceed $25,000;
    
 
                                       48
<PAGE>
   
(2) the proceeds (in any amount) are to be paid to someone OTHER THAN the
    registered owner(s) of the account;
    
 
   
(3) the proceeds (in any amount) are to be sent to any address OTHER THAN the
    shareholder's address of record, pre-authorized bank account or exchanged to
    one of the other funds managed by SM&R; or
    
 
   
(4) the Company or its transfer agent believes a signature guarantee would
    protect against potential claims based on the transfer instructions,
    including, when the authority of a representative of a corporation,
    partnership, association, or other entity has not been established to the
    satisfaction of the Company or transfer agent.
    
 
   
You should be able to obtain an acceptable signature guarantee from a bank,
broker, dealer, municipal securities dealer or broker, government securities
dealer or broker, credit union, national securities exchange, or registered
securities association. WITNESSING OR NOTARIZATION IS NOT SUFFICIENT.
    
 
   
TEXAS OPTIONAL RETIREMENT PROGRAM. You may not redeem shares of the Government
Bond Fund, Primary Fund, and Money Market Fund in any account established under
the Texas Optional Retirement Program, unless SM&R receives satisfactory
evidence from the state that one of the following conditions exist:
    
 
   
(1) death of the employee;
    
 
   
(2) termination of service with the employer; or
    
 
   
(3) retirement of employee.
    
 
   
CHECK WRITING OPTION. Check writing is available in the Money Market Fund to
investors having an account value of $1,000 or more. $250 is the minimum check
amount under the check writing option. This option is not available on IRAs or
TSAs. Shareholders wishing to avail themselves of this option must complete the
check writing option signature card in the Prospectus. After obtaining specimen
signatures and the fully executed card, SM&R will order checks and arrange for
the shareholder's checks to be honored by a bank. Investments made by personal
check or third party check will be held for fifteen (15) business days following
the investment during which time checks may not be drawn on the amount of such
investment. This service may be terminated or suspended or additional charges
may
    
 
                                       49
<PAGE>
   
be imposed for this service. Shareholders will be provided the initial checkbook
free of charge. There will be a $5 fee for re-orders. Shareholders will be
allowed to write ten (10) checks free each calendar quarter.
    
 
   
When a check is presented for payment, SM&R, as the shareholder's agent, will
cause each fund to redeem a sufficient number of full and fractional shares to
cover the amount of the check. Shareholders will continue to be entitled to
dividends on their shares up to the time the check is presented to SM&R for
payment. If the amount of the check is greater than the value of the shares held
in the shareholder's account for more than fifteen (15) business days at the
time the check is presented for payment, the check will be returned to the payee
as not being covered by sufficient funds, and the shareholder will be subject to
extra charges as a result.
    
 
   
Primary Fund shareholders that had check writing privileges prior to December
31, 1998 will be permitted to continue writing checks on the Primary Fund
subject to the terms applicable to the Money Market Fund described above.
SHAREHOLDERS USING THE PRIMARY FUND CHECK WRITING OPTION SHOULD BE AWARE THAT
WRITING A CHECK IS A REDEMPTION OF SHARES. THOSE SHARES MAY BE WORTH LESS WHEN
THE CHECK IS PRESENTED FOR PAYMENT THAN WHEN THE CHECK WAS WRITTEN.
    
 
   
REDEMPTION OF SMALL ACCOUNTS. The Company reserves the right to redeem shares in
any account (which will be promptly paid to the shareholder) if, due to your
redemptions, the value of the account falls below $100 in the case of the
Government Bond and Tax Free Funds or $1,000 in the case of the Primary and
Money Market Funds. You will be notified that the value of your account is less
than the required minimum indicated above and allowed at least 60 days to make
an additional investment to increase the value of your account above the
required minimum. The Board of Directors may, from time to time, change such
required minimum investment.
    
 
   
RIGHTS RESERVED BY THE COMPANY. The Company, acting through its transfer agent,
reserves the right:
    
 
   
  - to waive or lower investment minimums;
    
 
   
  - to accept initial purchases by telephone from a registered representative;

INVESTMENT ADVISOR
    
 
   
The Company's Board of Directors has delegated to Securities Management and
Research, Inc. ("SM&R"), the funds' investment adviser, the management of the
funds' day-to-day business and affairs. In addition, SM&R invests the funds'
assets, provides administrative services, and serves as transfer agent,
custodian, dividend paying agent, and underwriter.
    
 
   
SM&R is a wholly-owned subsidiary of American National Insurance Company
("American National"). SM&R was incorporated in 1964 and has managed mutual
funds since 1966. SM&R does and may, from time to time, serve as investment
adviser to other clients including employee benefit plans, other investment
companies, banks, foundations and endowment funds.
    
 
   
Under the Advisory Agreements with the Company, SM&R is paid an investment
advisory fee, which is calculated separately for each fund, as compensation for
its services. The agreement provides that SM&R will receive advisory fees as set
forth below.

REIMBURSEMENTS AND WAIVERS
    
 
   
SM&R has agreed to pay (or to reimburse each fund for) each fund's regular
operating expenses in excess of 1.25% (0.35% for the Money Market Fund) per year
of such fund's average daily net assets. Regular operating expenses include the

Fund for the fiscal year ended August 31, 1998 of each fund's average daily net
assets. The Money Market Fund was not in operation during the fiscal year ended
August 31, 1998.
    
 
   
In order to improve the yield and total return of any fund of the Company, SM&R
may from time to time voluntarily waive or reduce all or any portion of its
advisory fee, administrative fee, and/or assume certain or all expenses of any
fund of the Company while retaining its ability to be reimbursed for such fees
prior to the end of the fiscal year. Fee waivers and/or reductions, other than
those stated in the Administrative Service Agreement, may be rescinded by SM&R
at any time without notice to investors. SM&R has agreed to continue to waive
the advisory fee for the Tax Free Fund and reimburse expenses incurred by the
Government Bond and Primary Funds to the extent that regular operating expenses
exceed average daily net assets as follows: 0.80% for the Primary Fund and 1.00%
for the Government Bond Fund.

- -------------------------------------------------------------------
 
   
The following financial highlights table is intended to help you understand the
Government Bond Fund's financial performance for the past five years. Certain
information reflects financial results for a single share outstanding throughout
each period shown. The total returns in the table represent the rate that an
investor would have earned (or lost) on an investment in the Government Bond
Fund (assuming reinvestment of all dividends and distributions) prior to
addition of multiple classes of shares, but do not reflect any sales loads that
would be imposed on the purchase or sale of any shares. This information is
derived from the financial statements of the Government Bond Fund which for the
years ended through August 31, 1997 have been audited by KPMG Peat Marwick LLP
and for the year ended August 31, 1998 has been audited by Tait, Weller & Baker,
CPA. Each independent auditor's report, along with the Government Bond Fund's
financial statements, are incorporated by reference into the Statement of
Additional Information, which is available upon request.

- -------------------------------------------------------------------
 
   
The following financial highlights table is intended to help you understand the
Primary Fund's financial performance for the past five years. Certain
information reflects financial results for a single Primary Fund share
outstanding throughout each period shown. The total returns in the table
represent the rate that an investor would have earned (or lost) on an investment
in the Primary Fund (assuming reinvestment of all dividends and distributions).
This information is derived from the financial statements of the Primary Fund
which for the years ended through August 31, 1997 have been audited by KPMG Peat
Marwick LLP and for the year ended August 31, 1998 has been audited by Tait,
Weller & Baker, CPA. Each independent auditor's report, along with the Primary
Fund's financial statements, are incorporated by reference into the Statement of
Additional Information, which is available upon request.

(Description of Ratings Used in Prospectus)
    
- -------------------------------------------------------------------
 
   
BOND RATINGS
    
 
   
DESCRIPTION OF STANDARD & POOR'S CORPORATION'S BOND RATING:
    
 
   
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 obligations 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 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, which
       could lead to the obligor's inadequate capacity to meet its financial
       commitment on the obligation.
    
 
   
B     An obligation rated "B" is more vulnerable to nonpayment than obligations
       rated "BB," but the obligor currently has the capacity to meet its
       financial commitment on the obligation. Adverse business, financial, or
       economic conditions will likely
    
 
                                      A-1
<PAGE>
   
       impair the obligor's capacity or willingness to meet its financial
       commitment on the obligation.
    
 
   
DESCRIPTION OF MOODY'S INVESTOR'S SERVICE, INC.'S BOND RATINGS:
    
 
   
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-edge." 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,
       fluctuation of protective elements may be of greater amplitude, or there
       may be other elements present which make the long-term risks appear
       somewhat greater than in Aaa securities.
    
 
   
A     Bonds which are rated "A" possess many favorable investment attributes and
       are to be considered as upper medium grade obligations. Factors giving
       security to principal and interest are considered adequate but elements
       may be present which suggest a susceptibility to impairment sometime in
       the future.
    
 
   
Baa   Bonds which are rated "Baa" are considered as medium grade obligations,
       I.E., they are neither highly protected nor poorly secured. Interest
       payments and principal security appear adequate for the present, but
       certain protective elements may be lacking or may be characteristically
       unreliable over any great length of time. Such bonds lack outstanding
       investment characteristics and in fact have speculative characteristics
       as well.
    
 
   
Ba    Bonds which are rated "Ba" are judged to have speculative elements; their
       future cannot be considered as well assured. Often the protection of
       interest and principal payments may be very moderate and thereby not well
       safeguarded during both good and bad times over the future. Uncertainty
       of position characterizes bonds in this class.
    
 
                                      A-2
<PAGE>
   
B     Bonds which are rated "B" generally lack characteristics of the desirable
       investment. Assurance of interest and principal payments or of
       maintenance of other terms of the contract over any long period of time
       may be small.
    
 
   
DESCRIPTION OF FITCH INVESTORS SERVICE BOND RATINGS:
    
 
   
AAA  Obligations which have the highest rating assigned by Fitch IBCA on its
       national rating scale for that country. This rating is automatically
       assigned to all obligations issued or guaranteed by the sovereign state.
       Capacity for timely repayment of principal and interest is extremely
       strong, relative to other obligors in the same country.
    
 
   
AA   Obligations for which capacity for timely repayment of principal and
       interest is very strong relative to other obligors in the same country.
       The risk attached to these obligations differs only slightly from the
       country's highest rated debt.
    
 
   
A     Obligations for which capacity for timely repayment of principal and
       interest is strong relative to other obligors in the same country.
       However, adverse changes in business, economic or financial conditions
       are more likely to affect the capacity for timely repayment than for
       obligations in higher rated categories.
    
 
   
BBB  Obligations for which capacity for timely repayment of principal and
       interest is adequate relative to other obligors in the same country.
       However, adverse changes in business, economic or financial conditions
       are more likely to affect the capacity for timely repayment than for
       obligations in higher rated categories.
    
 
   
MUNICIPAL NOTE RATINGS
    
 
   
DESCRIPTION OF MOODY'S INVESTOR SERVICE INC.'S MUNICIPAL NOTE RATINGS:
    
 
   
MIG 1/VMIG 1 This designation denotes best quality. There is present strong
                protection by established cash flows, superior liquidity support
                or demonstrated broad-based access to the market refinancing.
    
 
                                      A-3
<PAGE>
   
MIG 2/VMIG 2 This designation denotes high quality. Margins of protection are
                ample although not so large as in the preceding group.
    
 
   
MIG 3/VMIG 3 This designation denotes favorable quality. All security elements
                are accounted for but there is lacking the undeniable strength
                of the preceding grades. Liquidity and cash flow protection may
                be narrow and market access for refinancing is likely to be less
                well established.
    
 
   
MIG 4/VMIG 4 This designation denotes adequate quality. Protection commonly
                regarded as required of an investment security is present and
                although not distinctly or predominantly speculative, there is
                specific risk.
    
 
   
DESCRIPTION OF STANDARD AND POOR'S MUNICIPAL NOTE RATINGS:
    
 
   
Until June 29, 1984, S&P used the same rating symbols for notes and bonds. After
June 29, 1984, for new municipal note issues due in three years or less the
ratings below usually will be assigned. Notes maturing beyond three years will
most likely receive a bond rating of the type recited above.
    
 
   
SP-1  Strong capacity to pay principal and interest. An issue determined to
       possess a very strong capacity to pay debt service is 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.
    
 
   
COMMERCIAL PAPER RATINGS
    
 
   
DESCRIPTION OF STANDARD & POOR'S CORPORATION'S THREE HIGHEST COMMERCIAL PAPER
RATINGS:
    
 
   
Commercial paper rated "A" by Standard & Poor's Corporation has the following
characteristics: Liquidity ratios are adequate to meet cash requirements.
Long-term senior debt is generally rated "A" or better. The issuer has access to
at least two additional channels of borrowing. Basic earnings and cash flow have
an upward trend with allowance made for unusual circumstances. Typically, the
issuer's industry is well established and the issuer has a strong position
within
    
 
                                      A-4
<PAGE>
   
the industry. The reliability and quality of management are unquestioned.
Relative strength or weakness of the above factors determine whether the
issuer's commercial paper is rated as follows:
    
 
   
A-1   This designation indicates that the degree of safety regarding timely
       payment is strong. Those issues determined to possess extremely strong
       safety characteristics are denoted with a plus sign (+) designation.
    
 
   
A-2   Capacity for timely payment on issues with this designation is
       satisfactory. However, the relative degree of safety is not as high as
       for issues designated 'A-1'.
    
 
   
DESCRIPTION OF MOODY'S INVESTORS SERVICE, INC.'S THREE HIGHEST COMMERCIAL PAPER
RATINGS:
    
 
   
Among the factors considered by Moody's Investors Service, Inc. is assigning
commercial paper ratings are the following: (1) evaluation of the management of
the issuer; (2) economic evaluation of the issuer's industry or industries and
an appraisal of the risks which may be inherent in certain areas; (3) evaluation
of the issuer's products in relation to competition and customer acceptance; (4)
liquidity; (5) amount and quality of long-term debt; (6) trend of earnings over
a period of ten years; (7) financial strength of a parent company and the
relationships which exist with the issuer; and (8) recognition of the management
of obligations which may be present or may arise as a result of public interest
questions and proportions to meet such obligations. Relative differences in
strength and weakness in respect to these criteria would establish a rating in
one of three classifications; "P-1," "P-2" or "P-3."
    
 
   
DESCRIPTION OF FITCH INVESTORS SERVICE COMMERCIAL PAPER, MEDIUM-TERM NOTES, AND
MUNICIPAL AND INVESTMENT NOTES.
    
 
   
F-1+  Exceptionally Strong Credit Quality. Issues assigned this rating are
       regarded as having the strongest degree of assurance for timely payment.
    
 
   
F-1   Very Strong Credit Quality. Issues assigned this rating reflect an
       assurance of timely payment only slightly less in degree than issues
       rated "F-1+."
    
 
   
F-2   Good Credit Quality. Issues assigned this rating have a satisfactory
       degree of assurance for timely payment, but the margin of safety is not
       as great as for issues assigned "F-1+" and "F-1" ratings.
    
 
   
F-3   Fair Credit Quality. Issues assigned this rating have characteristics
       suggesting that the degree of assurance for timely
    
 
                                      A-5
<PAGE>
   
       payment is adequate, however, near-term adverse changes could cause these
       securities to be rated below investment grade.
    
 
   
F-5   Weak Credit Quality. Issues assigned this rating have characteristics
       suggesting a minimal degree of assurance for timely payment and are
       vulnerable to near-term adverse changes in financial and economic
       conditions.
    
 
   
DESCRIPTION OF DUFF & PHELP'S TWO HIGHEST COMMERCIAL RATINGS:
    
 
   
Duff & Phelp's commercial paper ratings place emphasis on liquidity, considering
not only cash from operations, but access to alternative sources of funds,
including trade credit, bank lines and capital markets. Relative differences in
strength and weakness is rated by Duff & Phelp's as Duff-1 or Duff-2; Duff-1
being the highest commercial paper rating and Duff-2 being the second highest
rating.
    
 
   
DESCRIPTION OF THOMSON BANKWATCH, INC.'S TWO HIGHEST COMMERCIAL RATINGS:
    
 
   
Thomson Bankwatch, Inc.'s ratings of United States commercial banks, thrifts,
and non-bank banks, non-United States banks, and broker-dealers are based upon
among other things, five years's financial information and the issuer's most
recent regulatory filings. Relative differences in strength and weakness are
rated by Thomson Bankwatch, Inc.
    
 
   
TBW-1 The highest category; indicates a very high likelihood that principal and
       interest will be paid on a timely basis.
    
 
   
TBW-2 The second-highest category; while the degree of safety regarding timely
       repayment of principal and interest is strong, the relative degree of
       safety is not as high as for issues rated TBW-1.

                                  THE COMPANY
    
 
   
    SM&R Investments, Inc. (the "Company") is a diversified, open-end management
investment company incorporated under the laws of Maryland on November 6, 1991.
The Company changed its name from SM&R Capital Funds, Inc. to SM&R Investments,
Inc. on              , 1998.
    
 
   
    The Company is registered under the Investment Company Act of 1940, as
amended (the "1940 Act") as a diversified, open-end management investment
company, commonly called a "mutual fund." This registration does not imply any
supervision by the Securities and Exchange Commission (the "Commission") over
the Company's management or its investment policies or practices.
    
 
   
    The Company consists of four (4) separate series or portfolios (each, a
"Fund"):
    
 
   
    - SM&R GOVERNMENT BOND FUND (formerly, American National Government Income
      Fund Series) ("Government Bond Fund");
    
 
   
    - SM&R TAX FREE FUND (formerly, American National Tax Free Fund Series) (the
      "Tax Free Fund");
    
 
   
    - SM&R PRIMARY FUND (formerly, American National Primary Fund Series) (the
      "Primary Fund"); and
    
 
   
    - SM&R MONEY MARKET FUND (the "Money Market Fund").
    
 
   
    The Government Bond Fund and the Tax Free Fund (the "Multi-Class Funds") are
each divided into six classes of shares (the "Classes") of common stock
designated as:
    
 
   
    - Class T (existing shareholders and certain designated persons);
    
 
   
    - Class A (front-end load);
    
 
   
    - Class B (back-end load);
    
 
   
    - Class C (level load);
    
 
   
    - Class J (network);
    
 
   
    - Class Y (institutional shareholders).
    
 
   
    These classes of shares have different sales charges and distribution and
service (12b-1) fee structures. A Multiple Class Plan was adopted for the
Multi-Class Funds pursuant to Rule 18f-3. The Primary Fund and Money Market Fund
do not have separate classes (that is, each is a "Single-Class Fund").

                       INVESTMENT OBJECTIVES AND POLICIES
    
 
   
    As noted in the Prospectuses under "Investment Objectives and Policies,"
each Fund has its own investment objective and follows policies and techniques
designed to achieve those objectives.
    
 
   
FUNDAMENTAL INVESTMENT RESTRICTIONS
    
 
   
    Each Fund's investment objective and the following restrictions have been
adopted as fundamental policies. (A fundamental policy may not be changed
without the approval of shareholders.)
    
 
   
    Each Fund:
    
 
   
    1.  With respect to 75% of the Fund's total assets, may not purchase
       securities of an issuer (other than cash or cash items, or securities of
       the U.S. Government, its agencies, or instrumentalities or of other
       investment companies), if (i) such purchase would cause more than 5% of
       the Fund's total assets taken at market value to be invested in the
       securities of such issuer, or (ii) such purchase would at the time result
       in more than 10% of the outstanding voting securities of such issuer
       being held by the Fund.
    
 
   
    2.  May not invest 25% or more of its total assets in the securities of one
       or more issuers conducting their principal business activities in the
       same industry (excluding the U.S. Government or any of its agencies or
       instrumentalities).
    
 
   
    3.  May not borrow money, except (a) the Fund may borrow from banks (as
       defined in the Act) or through reverse repurchase agreements in amounts
       up to 33 1/3% of its total assets (including the amount borrowed), (b)
       the Fund may, to the extent permitted by applicable law, borrow up to an
       additional 5% of its total assets for temporary purposes, (c) the Fund
       may obtain such short-term credits as may be necessary for the clearance
       of purchases and sales of portfolio securities, (d) the Fund may purchase
       securities on margin to the extent permitted by applicable law, and (e)
       the Fund may engage in transactions in mortgage dollar rolls which are
       accounted for as financings.
    
 
   
    4.  May not make loans, except through (a) the purchase of debt obligations
       in accordance with the Fund's investment objective and policies, (b)
       repurchase agreements with banks, brokers, dealers, and other financial
       institutions, and (c) loans of securities as permitted by applicable law.
    
 
   
    5.  May not underwrite securities issued by others, except to the extent
       that the sale of portfolio securities by the Fund may be deemed to be an
       underwriting.
    
 
   
    6.  May not purchase, hold or deal in real estate, although the Fund may
       purchase and sell securities that are secured by real estate or interests
       therein, securities of real estate investment trusts, and
       mortgage-related securities and may hold and sell real estate acquired by
       the Fund as a result of the ownership of securities.
    
 
                                       2
<PAGE>
   
    7.  May not invest in commodities or commodity contracts, except that the
       Fund may invest in currency and financial instruments and contracts that
       are commodities or commodity contracts.
    
 
   
    8.  May not issue senior securities to the extent such issuance would
       violate applicable law.
    
 
   
    The above investment restrictions are fundamental policies that may be
changed by the Fund only with the approval of a majority of the outstanding
shares of the Fund, as determined by the provisions of the 1940 Act. This means
that shareholders of the Fund must approve any change to the foregoing
restrictions before that change may be effected. Such approval requires the
affirmative vote of the lesser of (i) 67% or more of the voting securities
present at a meeting if the holders of more than 50% of voting securities are
represented at that meeting or (ii) more than 50% of the outstanding voting
securities of the Fund.
    
 
   
NON-FUNDAMENTAL INVESTMENT POLICIES
    
 
   
    The Board of Directors of the Company (the "Board") has adopted the
following non-fundamental investment policies. Non-fundamental investment
policies may be adopted or changed by the Board of Directors, without approval
from shareholders.
    
 
   
    Each Fund will not:
    
 
   
    1.  Issue senior securities.
    
 
   
    2.  Engage in the strategy of short sales of securities.
    
 
   
    3.  Purchase securities on margin (but it may obtain such short-term credits
       as may be necessary for the clearance of purchases and sales of
       securities).
    
 
   
    4.  Acquire, lease or hold real estate except such as may be necessary or
       advisable for the maintenance of its offices.
    
 
   
    5.  Write or purchase from others, put and call options, or any combination
       thereof.
    
 
   
    6.  Purchase or sell commodities or commodity contracts including futures
       contracts.
    
 
   
    7.  Invest in companies for the purpose of exercising control or management.
    
 
   
    8.  Invest in oil, gas or other mineral exploration or development programs.
       However, any Fund may invest in securities which are secured by real
       estate or real estate mortgages; securities of issuers which invest or
       deal in real estate mortgages and securities of issuers which invest in
       or sponsor oil, gas, or other mineral exploration, provided such
       securities meet the criterion set forth under "Investment Objectives and
       Policies" in the Prospectuses.
    
 
                                       3
<PAGE>
   
    9.  Act as underwriter of securities issued by other persons except insofar
       as the Fund may be technically deemed an underwriter under the federal
       securities laws in connection with the disposition of portfolio
       securities.
    
 
   
    10. Borrow money, except for such action by the Fund for temporary or
       emergency purposes in an amount not to exceed 10% of the Fund's net
       assets.
    
 
   
    11. Lend any funds or other assets, except that the Government Bond Fund may
       from time to time lend the securities it holds to qualified
       broker-dealers or other institutional investors. Such loans shall not
       exceed ten percent (10%) of the Government Bond Fund's net assets at the
       time of the most recent loan and shall be made pursuant to written
       agreements and shall be continuously secured by collateral in the form of
       cash, U.S. Government obligations, or irrevocable standby letters of
       credit in an amount equal to at least 102% of the market value at all
       times of the loaned securities plus the accrued interest and dividends.
       During the time securities are on loan, the Government Bond Fund will
       continue to receive the interest and dividends, or amounts equivalent
       thereto, on the loaned securities while receiving a fee from the borrower
       or earning interest on the investment of the cash collateral. The right
       to terminate the loan will be given to either party subject to
       appropriate notice. Upon termination of the loan, the borrower will
       return to the lender securities identical to the loaned securities. The
       Government Bond Fund will not have the right to vote securities on loan,
       but would terminate the loan and retain the right to vote if that were
       considered important with respect to the investment.
    
 
   
    12. Pledge or mortgage any of its assets, except for such action by the Fund
       for temporary or emergency purposes in an amount not to exceed 10% of the
       Fund's net assets.
    
 
   
    13. Invest more than 5% of the value of the net assets of the Fund, at time
       of purchase in the securities of any one issuer, but this limitation does
       not apply to investments in securities issued or guaranteed by the U.S.
       government or its instrumentalities.
    
 
   
    14. Purchase any security (other than United States Government obligations)
       if, as a result, the Fund would hold more than (a) 10% of the total value
       of any class of outstanding securities of an issuer or (b) 10% of the
       outstanding voting securities of an issuer.
    
 
   
    15. Concentrate more than 25% of the net assets of the Fund in any one
       industry or group of industries; provided however, there is no limitation
       with respect to investments in obligations issued or guaranteed by the
       United States Government or its agencies or instrumentalities. For
       purposes of this restriction, telephone, gas and electric public
       utilities are each regarded as separate industries.
    
 
                                       4
<PAGE>
   
    16. Purchase any securities issued by a corporation which has not been in
       continuous operation for three years, but such period may include the
       operation of a predecessor.
    
 
   
    17. Purchase or retain securities of any issuer if any officer or director
       of the Company or of its investment manager own individually more than
       one-half of one percent ( 1/2 of 1%) of the securities of that issuer,
       and collectively the officers and directors of the Company and investment
       manager together own more than 5% of the securities of that issuer.
    
 
   
    18. Purchase securities of other investment companies except pursuant to a
       plan of merger, consolidation or acquisition of assets approved by the
       Company's shareholders.
    
 
   
    19. Invest in foreign securities, except that this policy does not apply to
       the Government Bond Fund.
    
 
   
    20. Purchase warrants.
    
 
   
    21. Purchase any security which is an "illiquid security" if more than 15%
       (10% for the Money Market Fund) of the net assets of the Fund taken at
       market value would be invested in such securities.
    
 
   
    If a percentage restriction on investment or utilization of assets as set
forth is adhered to at the time an investment is made, a later change in the
percentage resulting from a change in the value or cost of a Fund's assets will
not be considered a violation of the restriction except as provided in 17 above.
    
 
   
INVESTMENT TECHNIQUES
    
 
   
    LENDING PORTFOLIO SECURITIES.  Consistent with applicable regulatory
requirements, the Government Bond Fund may lend its portfolio securities to
broker-dealers and other financial institutions, to a maximum of 10% of the
value of its net assets at the time of the most recent loan. Such loans must be
callable at any time and continuously secured by cash collateral equal at all
times to at least 102% of the market value of the securities loaned, including
accrued interest.
    
 
   
    The market value of the securities loaned shall be monitored daily, and the
borrower must increase the collateral whenever the market value of the
securities loaned rises above the level of the collateral. Cash collateral shall
be invested in short-term instruments that are sufficiently liquid to provide
for repayment upon demand (such as bank letters of credit, U.S. Government
Obligations, or other cash equivalents). Cash or instruments collateralizing the
Fund's loans of securities will be segregated and maintained at all times with
SM&R, the Fund's custodian, in an amount at least equal to the current market
value of the loaned securities. The Government Bond Fund will receive amounts
equal to earned income for having made the loan.
    
 
   
    The Government Bond Fund will be the beneficial owner of the loaned
securities in that any gain or loss in the market price during the loan inures
to the Government Bond
    
 
                                       5
<PAGE>
   
Fund and its shareholders. Thus, when a loan is terminated, the value of the
securities may be more or less than their value at the beginning of the loan. In
determining whether to lend its portfolio securities to a broker-dealer or other
financial institution, the Government Bond Fund will take into account the
creditworthiness of such borrower and will monitor such creditworthiness on an
ongoing basis inasmuch as default by the other party may cause delays or other
collection difficulties. The Government Bond Fund may pay placing brokers' fees
in connection with loans of its portfolio securities.
    
 
   
    In lending its portfolio securities, the Government Bond Fund is subject to
the risk that the borrower may become insolvent on a day on which the loaned
security is rapidly advancing in price. In that event, the borrower may fail to
return the loaned securities while the cash collateral is insufficient to
purchase the full amount of the security loaned, and the borrower would be
unable to furnish additional collateral. The borrower would be liable for any
shortage; but the Government Bond Fund would be an unsecured creditor with
respect to such shortage and might not be able to recover any of it. However,
this risk may be minimized by a careful selection of borrowers and securities to
be lent and by monitoring collateral.
    
 
   
    The Government Bond Fund will not lend securities to broker-dealers
affiliated with SM&R. This restriction will not affect the ability of the Fund
to maximize its securities lending opportunities.
    
 
   
    U.S. TREASURY SECURITIES.  Each Fund may invest in U.S. Treasury securities,
including bills, notes and bonds issued by the U.S. Treasury. These instruments
are direct obligations of the U.S. Government and, as such, are backed by the
full faith and credit of the United States. They differ primarily in their
interest rates, the lengths of their maturities and the dates of their
issuances.
    
 
   
    U.S. GOVERNMENT OBLIGATIONS.  Each Fund may invest in direct or implied
obligations of the U.S. Government, its agencies or instrumentalities ("U.S.
Government Obligations"). These U.S. Government Obligations, including those
that are guaranteed by federal agencies or instrumentalities, may or may not be
backed by the full faith and credit of the United States. Obligations of the
Government National Mortgage Association ("GNMA" or "Ginnie Mae"), the Farmers
Home Administration and the Export-Import Bank are backed by the full faith and
credit of the United States. Securities that are not backed by the full faith
and credit of the United States include, among others, obligations issued by the
Tennessee Valley Authority, the Resolution Trust Corporation, the Federal
National Mortgage Association ("FNMA" or "Fannie Mae"), the Federal Home Loan
Mortgage Corporation ("FHLMC" or "Freddie Mac") and the United States Postal
Service, each of which has the right to borrow from the United States Treasury
to meet its obligations. In addition, obligations of the Federal Farm Credit
Bank and the Federal Home Loan Bank may be satisfied only by the individual
credit of the issuing agency. Investments in Freddie Mac, and Fannie Mae and
other obligations may include collateralized mortgage obligations ("CMOs") and
real estate mortgage investment conduits issued or guaranteed by such entities.
    
 
                                       6
<PAGE>
   
    In the case of U.S. Government Obligations not backed by the full faith and
credit of the United States, the Company must look principally to the agency
issuing or guaranteeing the obligation for ultimate repayment and may not be
able to assert a claim against the U.S. if the agency or instrumentality does
not meet its commitments. There is no guarantee that the U.S. Government will
support securities not backed by its full faith and credit. Accordingly,
although these securities have historically involved little risk of loss of
principal if held to maturity, they may involve more risk than securities backed
by the U.S. Government's full faith and credit.
    
 
   
    MORTGAGE-BACKED U.S. GOVERNMENT OBLIGATIONS.  The Government Bond Fund may
invest in mortgage-backed securities issued or guaranteed by U.S. Government
agencies such as GNMA, FNMA or FHLMC and representing undivided ownership
interests in pools of mortgages. The mortgages backing these securities may
include conventional 30-year fixed rate mortgages, 15-year fixed rate mortgages,
graduated payment mortgages and adjustable rate mortgages.
    
 
   
    The U.S. Government or the issuing agency guarantees the payment of the
interest on and principal of these securities. However, the guarantees do not
extend to the securities' yield or value, which are likely to vary inversely
with fluctuations in interest rates, nor do the guarantees extend to the yield
or value of the Government Bond Fund's shares. These securities are in most
cases "pass-through" instruments, through which the holders receive a share of
all interest and principal payments from the mortgages underlying the
securities, net of certain fees. Because the principal amounts of such
underlying mortgages may generally be prepaid in whole or in part by the
mortgagees at any time without penalty and the prepayment characteristics of the
underlying mortgages vary, it is not possible to predict accurately the average
life of a particular issue of pass-through securities. Mortgage-backed
securities are subject to more rapid repayment than their stated maturity date
would indicate as a result of the pass-through of prepayments on the underlying
mortgage obligations. The remaining maturity of a mortgage-backed security will
be deemed to be equal to the average maturity of the mortgages underlying such
security determined by SM&R on the basis of assumed prepayment rates with
respect to such mortgages. The remaining expected average life of a pool of
mortgages underlying a mortgage-backed security is a prediction of when the
mortgages will be repaid and is based upon a variety of factors such as the
demographic and geographic characteristics of the borrowers and the mortgaged
properties, the length of time that each of the mortgages has been outstanding,
the interest rates payable on the mortgages and the current interest rate
environment. While the timing of prepayments of graduated payment mortgages
differs somewhat from that of conventional mortgages, the prepayment experience
of graduated payment mortgages is basically the same as that of the conventional
mortgages of the same maturity dates over the life of the pool. During periods
of declining interest rates, prepayment of mortgages underlying mortgage-backed
securities can be expected to accelerate. When the mortgage obligations are
prepaid, the Government Bond Fund reinvests the prepaid amounts in other income
producing securities, the yields of which reflect interest rates prevailing at
the time.
    
 
                                       7
<PAGE>
   
Therefore, the Government Bond Fund's ability to maintain a portfolio of
high-yielding mortgage-backed securities will be adversely affected to the
extent that prepayments of mortgages must be reinvested in securities which have
lower yields than the prepaid mortgage-backed securities. Moreover, prepayments
of mortgages which underlie securities purchased by the Government Bond Fund at
a premium would result in capital losses.
    
 
   
    INFLATION-INDEXED BONDS.  The Government Bond Fund may invest in inflation-
indexed bonds, which are fixed income securities whose principal value is
periodically adjusted according to the rate of inflation. The interest rate on
these bonds is generally fixed at issuance at a rate lower than typical bonds.
Over the life of an inflation-indexed bond, however, interest will be paid based
on a principal value that is adjusted for inflation. Inflation-indexed
securities issued by the U.S. Treasury will initially have maturities of five or
ten years, although it is anticipated that securities with other maturities will
be issued in the future. The securities will pay interest on a semi-annual
basis, equal to a fixed percentage of the inflation-adjusted principal amount.
    
 
   
    If the periodic adjustment rate measuring inflation fails, the principal
value of inflation falls, the principal value of inflation-indexed bonds will be
adjusted downward, and consequently the interest payable on these securities
(calculated with respect to a smaller principal amount) will be reduced.
Repayment of the original bond principal upon maturity (as adjusted for
inflation) is guaranteed in the case of U.S. Treasury inflation-indexed bonds,
even during a period of deflation. However, the current market value of the
bonds is not guaranteed and will fluctuate.
    
 
   
    The U.S. Treasury has only recently begun issuing inflation-indexed bonds.
As such, there is no trading history of these securities, and there can be no
assurance that a liquid market in these instruments will develop, although one
is expected. Lack of a liquid market may impose the risk of higher transaction
costs and the possibility the fund may be forced to liquidate positions when it
would not be advantageous to do so.
    
 
   
    Any increase in the principal amount of an inflation-indexed bond will be
considered taxable ordinary income, even though investors do not receive their
principal until maturity.
    
 
   
    COLLATERALIZED OBLIGATIONS.  The Government Bond Fund and the Money Market
Fund each may invest a portion of its assets in collateralized mortgage
obligations or "CMOs" issued or guaranteed by a U.S. Government agency or
instrumentality, such as the FHLMC. A CMO is a debt security issued by a
corporation, trust or custodian, or by a U.S. Government agency or
instrumentality, that is collateralized by a portfolio or pool of mortgages,
mortgage-backed securities or U.S. Government Obligations. The issuer's
obligation to make interest and principal payments is secured by the underlying
pool or portfolio of securities. A variety of types of collateralized
obligations are available currently and others may become available in the
future.
    
 
   
    The Government Bond Fund and the Money Market Fund will not invest in any
CMOs that are not fully collateralized obligations. "Fully collateralized" means
that the
    
 
                                       8
<PAGE>
   
collateral will generate cash flows sufficient to meet obligations to holders of
the collateralized obligations under even the most conservative prepayment and
interest rate projections. Thus, the collateralized obligations are structured
to anticipate a worst case prepayment condition and to minimize the reinvestment
rate risk for cash flows between coupon dates for the collateralized
obligations. A worst case prepayment condition generally assumes immediate
prepayment of all securities purchased at a premium and zero prepayment of all
securities purchased at a discount. Reinvestment rate risk may be minimized by
assuming very conservative reinvestment rates and by other means such as by
maintaining the flexibility to increase principal distributions in a low
interest rate environment. The requirements as to collateralization are
determined by the issuer or sponsor of the collateralized obligation in order to
satisfy the U.S. Government agency or instrumentality guaranteeing the
obligation.
    
 
   
    Collateralized obligations are designed to be retired as the underlying
securities are repaid. In the event of prepayment on or call of such securities,
the class of collateralized obligations first to mature generally will be paid
down first. Therefore, although in most cases the issuer of collateralized
obligations will not supply additional collateral in the event of such
prepayment, there will be sufficient collateral to secure collateralized
obligations that remain outstanding.
    
 
   
    The Government Bond Fund may also invest in securities issued by private
issuers that represent an interest in or are secured by mortgage-backed
securities issued or guaranteed by the U.S. government or one of its agencies or
instrumentalities. In addition, the Government Bond Fund may invest in
securities issued by private issuers that represent an interest in or are
secured by mortgage loans or mortgage-backed securities without a government
guarantee but usually have some form of private credit enhancement.
    
 
   
    MORTGAGE PASS-THROUGH SECURITIES.  Additionally, the Government Bond Fund
may invest in mortgage pass-through securities that do not contain government
guarantees. Commercial banks, savings and loan institutions, private mortgage
insurance companies, mortgage bankers and other secondary market issuers also
create pass-through pools of conventional residential mortgage loans. Such
issuers may, in addition, be the originators and/or servicers of the underlying
mortgage loans as well as the guarantors of the mortgage-related securities.
Pools created by such non-governmental issuers generally offer a higher rate of
interest than government and government-related pools because there are no
direct or indirect government or agency guarantees of payments in the former
pools. However, timely payment of interest and principal of these pools may be
supported by various forms of insurance or guarantees, including individual
loan, title, pool and hazard insurance and letters of credit. The insurance and
guarantees are issued by governmental entities, private insurers and the
entities creating the mortgage pools. Such insurance and guarantees, and the
creditworthiness of the issuers thereof, will be considered in determining
whether a mortgage-related security meets the Government Bond Fund's investment
quality standards. There can be no assurance that the private
    
 
                                       9
<PAGE>
   
insurers or guarantors can meet their obligations under the insurance policies
or guarantee arrangements.
    
 
   
    OTHER ASSET-BACKED SECURITIES.  It is expected that new types of
asset-backed securities (unrelated to mortgage loans) may be available for
investment in the future and may be purchased by the funds that may invest in
mortgage-related securities. Several types of asset-backed securities have
already been offered to investors, such as home equity loan receivables.
Traditional home equity loans (HELs) are very similar to residential mortgages
which pass through principal payments (or amortize) over a time period.
Generally these securities have maturities of 10 to 20 years, which is modestly
shorter than a traditional 30-year first mortgage. Although some HELs evidence a
first lien on the underlying property, usually a first mortgage is in place
concurrently with a HEL. Another asset-backed security is a home equity line of
credit (HELOC), which is a line of credit extended to a property owner that can
be drawn upon, and paid down and then re-drawn upon until the line's final
maturity. This revolving feature results in HELOC cash flows looking very
similar to credit card cash flows. As with other pass-through securities, an
investor's return may be affected by early prepayment of principal on the
underlying loan.
    
 
   
    Consistent with the Government Bond Fund's investment objectives and
policies, the portfolio manager may invest in other types of asset-backed
securities.
    
 
   
    MUNICIPAL SECURITIES.  The Tax Free Fund intends under normal market
conditions to invest at least 80% of its net assets in municipal securities.
    
 
   
    As used in the Prospectuses and this Statement of Additional Information,
the term "municipal securities" means obligations including municipal bonds and
notes and tax exempt commercial paper issued by or on behalf of states,
territories and possessions of the United States, the District of Columbia and
their political subdivisions, agencies and instrumentalities, the interest from
which is, in the opinion of counsel to the issuers of such securities, exempt
from federal income tax. To the extent that an investment in municipal
securities does not run counter to any of the investment policies of the Tax
Free Fund or any of the investment restrictions to which the Tax Free Fund is
subject, the Fund may invest in any combination of the various types of
municipal securities described below which, in the judgment of SM&R, will
contribute to the attainment of the Fund's investment objective. Such
combination of municipal securities may vary from time to time. Discussed below
are the major attributes of the various municipal and other securities in which
the Tax Free Fund may invest.
    
 
   
    Municipal Bonds, which meet longer term capital needs and generally have
maturities of more than one year when issued, have two principal
classifications: general obligation bonds and revenue bonds.
    
 
   
    GENERAL OBLIGATION BONDS -- Issuers of general obligation bonds include
states, counties, cities, towns and regional districts. The proceeds of these
obligations are used to fund a wide range of public projects, including
construction or improvement of
    
 
                                       10
<PAGE>
   
schools, highways and roads and water and sewer systems. The basic security
behind general obligation bonds is the issuer's pledge of its full faith and
credit and taxing power for the payment of principal and interest. The taxes
that can be levied for the payment of debt service may be limited or unlimited
as to the rate or amount of special assessments.
    
 
   
    REVENUE BONDS -- The principal security for a revenue bond is generally the
net revenues derived from a particular facility, group of facilities, or, in
some cases, the proceeds of a special excise or other specific revenue source.
Revenue bonds are issued to finance a wide variety of capital projects
including: electric, gas, water and sewer systems; highways, bridges, and
tunnels; port and airport facilities; colleges and universities; and hospitals.
Although the principal security behind these bonds may vary, many provide
additional security in the form of a debt service reserve fund whose money may
be used to make principal and interest payments on the issuer's obligations.
Housing finance authorities have a wide range of security, including partially
or fully insured mortgages, rent subsidized and/or collateralized mortgages,
and/or the net revenues from housing or other public projects. Some authorities
provide further security in the form of a state's ability (without obligation)
to make up deficiencies in the debt service reserve fund.
    
 
   
    Industrial Development Bonds are, in most cases, revenue bonds and are
issued for or on behalf of public authorities to raise money to finance various
privately operated facilities for business and manufacturing, housing, sports
and pollution control. These bonds are also used to finance public facilities
such as airports, mass transit systems, ports and parking. The payment of the
principal and interest on such bonds is dependent solely on the ability of the
facilities user to meet its financial obligations and the pledge, if any, of
real and personal property so financed as security for such payment. The Tax
Free Fund will purchase Industrial Revenue Development Bonds only to the extent
the interest paid is tax-exempt pursuant to the Tax Reform Act of 1986, which
limited the types of facilities that may be financed with tax-exempt industrial
development and private activity bonds.
    
 
   
    Municipal notes generally are used to provide for short-term working capital
needs and generally have maturities of one year or less. Municipal notes
include:
    
 
   
    TAX ANTICIPATION NOTES ("TANS") -- TANS are issued to finance working
capital needs of municipalities and are issued in anticipation of various
seasonal tax revenue, such as income, sales, use and business taxes, and are
payable from these specific future taxes.
    
 
   
    REVENUE ANTICIPATION NOTES ("RANS") -- RANS are in expectation of receipt of
other types of revenue, such as federal revenues available under federal revenue
sharing programs.
    
 
   
    BOND ANTICIPATION NOTES ("BANS") -- BANS are issued to provide interim
financing until long-term financing can be arranged. In most cases, the
long-term bonds then provide the money for the repayment of the notes.
    
 
                                       11
<PAGE>
   
    CONSTRUCTION LOAN NOTES -- Construction Loan Notes are sold to provide
construction financing. After successful completion and acceptance, many
projects receive permanent financing through the Federal Housing Administration
under "Fannie Mae" (the Federal National Mortgage Association) or "Ginnie Mae"
(the Government National Mortgage Association).
    
 
   
    TAX-EXEMPT COMMERCIAL PAPER (SHORT-TERM DISCOUNT NOTES) -- Tax Exempt
Commercial Paper is a short-term obligation with a stated maturity of 365 days
or less. It is issued by state and local governments or their agencies to
finance seasonal working capital needs or as short-term financing in
anticipation of longer-term financing.
    
 
   
    Variable or Floating Rate Demand Notes ("VRDNs") are tax-exempt obligations
which contain a floating or variable interest rate adjustment formula and an
unconditional right of demand to receive payment of the unpaid principal balance
plus accrued interest upon a short notice period (generally up to 30 days) prior
to specified dates, either from the issuer or by drawing on a bank letter of
credit, a guarantee or insurance issued with respect to such instrument. The
interest rates are adjustable at intervals ranging from daily to up to six
months to some prevailing market rate for similar investments, such adjustment
formula being calculated to maintain the market value of the VRDN at
approximately the par value of the VRDN upon the adjustment date. The
adjustments are typically based upon the prime rate of a bank or some other
appropriate interest rate adjustment index. The Tax Free Fund will decide which
variable or floating rate demand instruments it will purchase in accordance with
procedures prescribed by the Board to minimize credit risks. Any VRDN must be of
high quality as determined by SM&R and subject to review by the Board with
respect to both its long-term and short-term aspects, except where credit
support for the instrument is provided even in the event of default on the
underlying security, the Fund may rely only on the high quality character of the
short-term aspect of the demand instrument.
    
 
   
    Defeased bonds or escrow secured bonds are created when an issuer refunds in
advance of maturity (or pre-refunds) an outstanding bond issue which is not
immediately callable, and it becomes necessary or desirable to set aside funds
for redemption of the bonds at a future date. In an advance refunding, the
issuer will use the proceeds of a new bond issue to purchase high grade,
interest bearing debt securities which are then deposited in an irrevocable
escrow account held by a trustee bank to secure all future payments of principal
and interest of the advance refunded bond. Escrow secured bonds will often
receive a triple A rating from Moody's and S&P. The Tax Free Fund will purchase
escrow secured bonds without additional insurance only when the escrow is
invested in U.S. government securities backed by the full faith and credit of
the U.S. government.
    
 
   
    Insured bonds are secured by the issuer's revenues and also are backed by
insurance policies written by commercial insurance companies. Issuers of
municipal bonds enter into a contractual agreement with an insurance company to
pay the bondholder any principal and interest that is due on a stated maturity
date which has not been paid by the issuer. Once issued, this default insurance
usually extends for the term of the issue
    
 
                                       12
<PAGE>
   
and cannot be canceled by the insurance company. The bondholder who has not
received payments for principal or interest on the stated due dates for the
insured bond must notify the insurance company and surrender any unpaid bonds
and coupons for payment of the face amount of the insured principal and
interest. The commercial insurance companies represent some of the largest and
financially strongest insurance companies in the United States.
    
 
   
    Although insured municipal bonds sell at yields lower than they would
without the insurance, they tend to have yields higher than Aaa/AAA-rated
noninsured municipal bonds.
    
 
   
    In addition, other types of municipal securities similar to the above
described municipal bonds and municipal notes are, or may become available. For
the purpose of the Company's investment restrictions set forth in this Statement
of Additional Information, the identification of the "issuer" of a municipal
security which is not a general obligation bond is made by the adviser on the
basis of the characteristics of the obligation, the most significant of which is
the source of funds for the payment of principal and interest on such security.
    
 
   
    RISKS RELATING TO MUNICIPAL SECURITIES.  There can be no assurance that the
Tax Free Fund will achieve its investment objective. Yields on municipal
securities are dependent on a variety of factors, including the general
conditions of the money market and the municipal bond market, the size of a
particular offering, the maturity of the obligations and the rating of the
issue. Municipal securities with longer maturities tend to produce higher yields
and are generally subject to potentially greater capital appreciation and
depreciation than obligations with shorter maturities. The market prices of
municipal securities usually vary, depending upon available yields. An increase
in interest rates will generally reduce the value of portfolio investments, and
a decline in interest rates will generally increase the value of portfolio
investments. The ability of the Fund to achieve its investment objective is also
dependent on the continuing ability of the issuers of municipal securities in
which the Fund invests to meet their obligations for the payment of interest and
principal when due. The ratings of Moody's, Standard & Poor's, and Fitch
represent their opinions as to the quality of municipal securities which they
undertake to rate. Ratings are not absolute standards of quality; consequently,
municipal securities with the same maturity, coupon and rating may have
different yields. There are variations in municipal securities, both within a
particular classification and between classifications, depending on numerous
factors. It should also be pointed out that, unlike other types of investments,
municipal securities have traditionally not been subject to regulation by, or
registration with, the Securities and Exchange Commission, although there have
been proposals which would provide for such regulation in the future.
    
 
   
    The federal bankruptcy statutes relating to the debts of political
subdivisions and authorities of states of the United States provide that, in
certain circumstances, such subdivisions or authorities may be authorized to
initiate bankruptcy proceedings without prior notice to or consent of creditors,
which proceedings could result in material and adverse changes in the rights of
holders of their obligations.
    
 
                                       13
<PAGE>
   
    Lawsuits challenging the validity under state constitutions of present
systems of financing public education have been initiated or adjusted in a
number of states, and legislation has been introduced to effect changes in
public school financing in some states. In other instances there have been
lawsuits challenging the issuance of pollution control revenue bonds or the
validity of their issuance under state or federal law which could ultimately
affect the validity of those municipal securities or the tax-free nature of the
interest thereon.
    
 
   
    In addition, Congress could enact tax legislation such as a flat tax rate
that would make tax-free bonds less desirable to investors seeking ways to
reduce taxable income. If that were to occur, it could cause the value of the
securities to drop.
    
 
   
    TAXABLE SECURITIES.  Each Fund, except the Tax Free Fund, invests primarily
in securities the income from which (either in the form of dividends or
interest) is taxable as ordinary income. Under normal market conditions, the Tax
Free Fund may invest up to 20% of its net assets in taxable securities, and may
invest a greater percentage of its net assets in taxable securities under
extraordinary circumstances as a temporary defensive measure.
    
 
   
    Interest earned on investments in taxable securities may be taxable to
shareholders as ordinary income. Investors should be aware that investments in
taxable securities by the Tax Free Fund are restricted to:
    
 
   
    U.S. Government Obligations, which consist of obligations issued or
    guaranteed by the U.S. Government, its agencies, authorities or
    instrumentalities. Some of these securities are supported by the full faith
    and credit of the U.S. Government; others are supported by the right of the
    issuer to borrow from the U.S. Treasury; and the remainder are supported
    only by the credit of the instrumentality.
    
 
   
    Corporate Debt Securities which at the date of the investment are rated A or
    higher by Moody's, Standard & Poor's, or Fitch.
    
 
   
    Commercial Paper which at the date of the investment is rated P-2 or higher
    by Moody's or A-2 or higher by S&P or, if not rated, is issued by a company
    which at the date of the investment has an outstanding debt issue rated A or
    higher by Moody's and Standard & Poor's.
    
 
   
    Bank Obligations, which include certificates of deposit, bankers'
    acceptances, and other short-term obligations of U.S. banks which at the
    date of the investment have a capital, surplus and undivided profits of $1
    billion as of the date of their most recently published financial statements
    (See "Certificate of Deposits" below).
    
 
   
    REPURCHASE AGREEMENTS.  Each Fund may enter into "repurchase agreements"
with banks or with government securities dealers, recognized by the Federal
Reserve Board and which have been approved by the Board. Under a repurchase
agreement, the Fund will acquire and hold a security (government security,
certificate of deposit, or banker's acceptance) subject to the seller's
agreement to repurchase the securities at a predetermined price within a
specified time (normally one day to one week), thereby determining
    
 
                                       14
<PAGE>
   
the yield during the Fund's holding period. During the holding period, the
seller must provide additional collateral if the market value of the obligation
falls below the repurchase price. In these transactions, the securities
purchased shall have an initial total value in excess of the value of the
repurchase agreement.
    
 
   
    The custodian for a Fund purchasing such repurchase agreement will hold the
securities underlying such repurchase agreement or such securities may be part
of the Federal Reserve Book Entry System. If the seller defaults or becomes
insolvent, the Fund could realize delays, costs or a loss in asserting its
rights to, or in liquidating, the collateral in satisfaction of the seller's
repurchase agreement. The Funds will enter into repurchase agreements only with
sellers who are believed to present minimal credit risks and will monitor the
value of the collateral during the holding period. Credit risks are evaluated
pursuant to guidelines adopted and regularly reviewed by the Board which set
forth credit worthiness standards for the banks and registered government
security dealers with whom the Funds may enter into such repurchase agreements.
Such arrangements permit each Fund to keep all of its assets at work while
retaining flexibility in pursuit of investments of a longer-term nature. No Fund
will purchase repurchase agreements maturing more than seven (7) days after such
purchase.
    
 
   
    RATINGS.  If the rating of a security purchased by a Fund is subsequently
reduced below the minimum rating required for purchase or a security purchased
by the Fund ceases to be rated, neither event will require the sale of the
security. However, the adviser will consider any such event in determining
whether the Fund should continue to hold the security. Any security held by the
Tax Free Fund which is subsequently downgraded below BBB by S&P or Baa by
Moody's will be sold as soon as it is advantageous to do so after the downgrade.
    
 
   
    WHEN-ISSUED AND DELAYED DELIVERY TRANSACTIONS.  The Government Bond Fund and
Tax Free Fund each may purchase and sell portfolio securities on a "when issued"
and "delayed delivery" basis. The price of such securities is fixed at the time
the commitment to purchase is made, but delivery and payment for such securities
take place at a later date. Normally, the settlement date occurs within one
month of the purchase. During the period between purchase and settlement,
generally no payment is made by the Fund to the issuer and no interest accrues
to the Fund. These transactions are subject to market fluctuations; the value of
the securities at delivery may be more or less than their purchase price, and
yields generally available on comparable securities when delivery occurs may be
higher than yields on the securities obtained pursuant to such transactions.
    
 
   
    Because the Government Bond Fund and Tax Free Fund each relies on the buyer
or seller, as the case may be, to consummate the transactions, failure by the
other party to complete a transaction may result in the Fund missing the
opportunity of obtaining a price or yield considered to be advantageous. When
the Government Bond Fund or Tax Free Fund is the buyer in such transactions,
however, it will maintain, in a segregated account with its custodian, cash,
short-term money market instruments, high quality debt
    
 
                                       15
<PAGE>
   
securities or portfolio securities having an aggregate value equal to the amount
of such purchase commitments until payment is made. The Government Bond Fund or
Tax Free Fund will make commitments to purchase securities on such basis only
with the intention of actually acquiring these securities, but it may sell such
securities prior to the settlement date if such sale is considered to be
advisable. No specific limitation exists as to the percentage of the Government
Bond Fund's or Tax Free Fund's assets which may be used to acquire securities on
a "when issued" or "delayed delivery" basis. To the extent either Fund engages
in "when issued" and "delayed delivery" transactions, it will do so for the
purpose of acquiring securities for its portfolio consistent with its investment
objective and policies and not for the purpose of investment leverage.
    
 
   
    FOREIGN DEBT SECURITIES.  The Government Bond Fund may invest up to 5% of
its assets in debt obligations of foreign corporations or financial
institutions, such as Yankee Bonds and Eurodollar Bonds. Yankee Bonds are U.S.
dollar-denominated obligations of foreign issuers that are issued in the United
States. Eurodollar Bonds are U.S. dollar-denominated obligations of U.S. or
foreign issuers that are traded outside the U.S., primarily in Europe.
    
 
   
    Yankee Bonds involve certain risks associated with investing in a foreign
issuer. Such risks may include nationalization of the issuer, confiscatory
taxation by the foreign government, establishment of controls by the foreign
government that would inhibit the remittance of amounts due the Fund, lack of
comparable publicly-available information concerning foreign issuers, lack of
comparable accounting and auditing practices in foreign countries and difficulty
in enforcing claims against foreign issuers in the event of default. Eurodollar
Bonds are subject to the same risks as domestic issues, in particular, credit
risk, market risk and liquidity risk. Eurodollar Bonds also are subject to
sovereign risk, including the risk that a foreign government might prevent
dollar-denominated funds from leaving the country. Eurodollar Bonds that are
issued by foreign issuers are subject to the same risks as Yankee Bonds.
    
 
   
    ILLIQUID SECURITIES.  Each Fund may invest up to 15% (10% for the Money
Market Fund) of its net assets in illiquid securities, including domestic or
foreign securities not listed on domestic or foreign exchanges and repurchase
agreements maturing in excess of seven days. Non-publicly traded securities may
be less liquid than publicly traded securities. Although these securities may be
resold in privately negotiated transactions, the prices realized from these
sales could be less than those originally paid by a Fund. In addition, companies
whose securities are not publicly traded are not subject to the disclosure and
other investor protection requirements that may be applicable if their
securities were publicly traded. A Fund's investments in illiquid securities are
subject to the risk that should the Fund desire to sell any of these securities
when a ready buyer is not available at a price that the Investment Manager deems
representative of their value, the value of the Fund's net assets could be
adversely affected.
    
 
   
    144A SECURITIES AND SECTION 4(2) COMMERCIAL PAPER.  If otherwise consistent
with its investment objective and policies, a Fund may purchase securities that
are not registered
    
 
                                       16
<PAGE>
   
under the Securities Act of 1933, as amended (the "1933 Act") but which can be
sold to "qualified institutional buyers" in accordance with Rule 144A under the
1933 Act, or which were issued under Section 4(2) of the 1933 Act. Due to
changing markets or other factors, 144A securities may be subject to a greater
possibility of becoming illiquid than securities which have been registered with
the SEC for sale.
    
 
   
    Any such security may be determined to be LIQUID under procedures adopted by
the Board. These procedures consider trading activity, availability of reliable
price information, and other relevant information to determine whether an
adequate trading market exists for that security. To the extent that, for a
period of time, qualified institutional or other buyers may cease purchasing
such restricted securities, the level of illiquidity of a Fund holding such
securities may increase.
    
 
   
    CERTAIN INVESTMENT GRADE OBLIGATIONS.  Although obligations rated BBB by S&P
or Baa by Moody's are considered investment grade, they may be viewed as being
subject to greater risks than other investment grade obligations. Obligations
rated BBB by S&P are regarded as having only an adequate capacity to pay
principal and interest and those rated Baa by Moody's are considered
medium-grade obligations that lack outstanding investment characteristics and
have speculative characteristics as well.
    
 
   
    CERTIFICATE OF DEPOSITS AND BANKERS ACCEPTANCES.  A certificate of deposit
generally is a short-term, interest-bearing negotiable certificate issued by a
commercial bank or savings and loan association against funds deposited in the
issuing institution. The interest rate may be fixed for the stated term or may
be periodically adjusted prior to the instrument's stated maturity, based upon a
specified market rate. A bankers' acceptance is a time draft drawn on a
commercial bank by a borrower, usually in connection with an international
commercial transaction to finance the import, export, transfer or storage of
goods. The borrower is liable for payment, as is the bank, which unconditionally
guarantees to pay the draft at its face amount on the maturity date. Most
bankers' acceptances have maturities of six months or less and are traded in
secondary markets prior to maturity.
    
 
   
    Savings and loan associations whose certificates of deposit may be purchased
by the Funds are subject to regulation and examination by the Office of Thrift
Supervision. Such certificates of deposit held by a Fund do not benefit
materially from insurance from the Federal Deposit Insurance Corporation.
    
 
   
    The Money Market Fund may not invest in any certificate of deposit or
bankers' acceptance of a commercial bank unless: the bank is organized and
operating in the United States, has total assets of at least $1 billion and is a
member of the Federal Deposit Insurance Corporation; or the bank is a foreign

    FOREIGN RISK FACTORS.  Obligations of foreign branches of U.S. banks are
subject to somewhat different risks than those of domestic banks. These risks
include foreign economic and political developments, foreign governmental
restrictions which may
    
 
                                       17
<PAGE>
   
adversely affect payment of principal and interest on the obligations, foreign
withholding and other taxes on interest income, and difficulties in obtaining
and enforcing a judgment against a foreign branch of a domestic bank. In
addition, different risks may result from the fact that foreign branches of U.S.
banks and U.S. branches of foreign banks are not necessarily subject to the same
or similar regulatory requirements that apply to domestic banks. For instance,
such branches may not be subject to the types of requirements imposed on
domestic banks with respect to mandatory reserves, loan limitations,
examinations, accounting, auditing, record keeping and the public availability
of information. Such obligations are not traded on any national securities
exchange. While the Primary Fund does not presently invest in obligations of
foreign branches of United States banks, it may do so in the future. Investments
in such obligations will not be made in excess of 10% of the Primary Fund's
total assets and will be made only when SM&R believes the risks described above
are minimal.
    
 
   
    MONEY MARKET FUND INVESTMENTS.  Pursuant to the 1940 Act, the Money Market
Fund may invest only in United States dollar-denominated instruments that
present minimal credit risks, have a remaining maturity of 397 calendar days or
less, and which are at the time of acquisition "eligible securities" as defined
in Rule 2a-7 under the 1940 Act. Generally, an eligible security is:
    
 
   
    - A security with a remaining maturity of 397 calendar days or less
      ("Short-term") that has received a rating from two nationally recognized
      statistical rating organizations ("NRSROs"), or if rated by only one
      NRSRO, from that NRSRO, in one of the two highest rating categories
      ("Acceptable Rating") for debt obligations; or
    
 
   
    - A security with a remaining maturity of 397 calendar days or less issued
      by an issuer that has received an Acceptable Rating from at least two
      NRSROs, or if rated by only one NRSRO, from that NRSRO, with respect to a
      class of debt obligations (or any debt obligation within that class) that
      is comparable in priority and security with the security (a "Comparable
      Security").
    
 
   
    If a security is acquired based on the rating of only one NRSRO, such
acquisition must be ratified by the Board. While Rule 2a-7 permits money market
funds to invest in certain unrated securities of comparable quality to eligible
rated securities, the Money Market Fund currently does not intend to invest in
unrated securities.
    
 
   
    SM&R has the responsibility of determining that each investment by the Money
Market Fund presents minimal credit risks. SM&R's determination of minimal
credit risk will be based on an analysis of the issuer's (and, if applicable,
any guarantor's) capacity to repay its Short-term debt obligations. The analysis
cannot rely on ratings alone, but must be made on factors pertaining to credit
quality in addition to any rating that the security or the issuer may have been
assigned. The extensiveness of the evaluation may vary with the type and
maturity of the instrument involved and the SM&R's familiarity with the issuer.
    
 
   
    The Money Market Fund will maintain a dollar-weighted average portfolio
maturity appropriate to its objective of maintaining a stable net asset value
per share, provided,
    
 
                                       18
<PAGE>
   
however, that the Fund will not (1) purchase any instrument with a remaining
maturity at the date of acquisition of greater than 397 calendar days, or (2)
maintain a dollar-weighted average portfolio Maturity that exceeds 90 days. The
"maturity" of a portfolio instrument is the period remaining (calculated from
the trade date or such other date on which the Fund's interest in the security
is subject to market action) until the date on which, in accordance with the
terms of the security, the principal amount must unconditionally be paid, or in
the case of a security called for redemption, the date on which the redemption
must be made.
    
 
   
    The Money Market Fund will maintain a diversified portfolio in accordance
with the provisions of Rule 2a-7. In meeting diversification requirements of the
Rule, SM&R classifies securities into First and Second Tier Securities, as
defined in the 1940 Act. A "First Tier Security" is an Eligible Security that
(1) has been rated by at least two NRSROs (or if rated by only one NRSRO, by
that NRSRO) in the highest rating category for Short-term debt obligations; (2)
has been issued by an issuer that is rated with respect to a Comparable
Security, by at least two NRSROs (or if rated by only one NRSRO, by that NRSRO)
in the highest rating category for Short-term debt obligations; (3) has been
issued by a registered investment company that is a money market fund; or (4) is
a "Government Security," as defined in Section 2(a)(16) of the 1940 Act. A
"Second Tier Security" is an Eligible Security that is not a First Tier
Security.
    
 
   
    Immediately after the acquisition of any security (other than a Government
Security), SM&R shall confirm that the Fund has not invested more than 5% of its
total assets in securities issued by any one issuer; provided, however, that the
Fund may invest up to 25% of its total assets in the First Tier Securities of a
single issuer for a period of up to three (3) business days after the purchase;
provided, further, that the Fund may not make more than one investment in
accordance with the foregoing provision at any time. Immediately after the
acquisition of a Second Tier Security, SM&R shall confirm that the Fund has not
invested more than (1) the greater of 1% of its total assets or one million
dollars in securities issued by that issuer that are Second Tier Securities, and
(2) 5% of its total assets in securities which, when acquired were, or have
become, Second Tier Securities.
    
 
   
                               PORTFOLIO TURNOVER
    
 
   
    Portfolio turnover is calculated by dividing the lesser of annual purchases
or sales of portfolio securities by the monthly average of the value of a Fund's
portfolio securities, excluding securities whose maturities at the time of
purchase are one (1) year or less. It is intended that portfolio changes in the
Government Bond Fund and Tax Free Fund be made as infrequently as possible,
consistent with market and economic factors generally, and special
considerations affecting any particular security such as the limitation of loss
or realization of price appreciation at a time believed to be opportune.

    The portfolio turnover rates for the Funds for past three fiscal years are
as follows:

</TABLE>
    
 
   
The Primary Fund experienced no portfolio turnover as the majority of securities
owned during the period had maturities of one year or less at the time of
acquisition. The Money Market Fund will not experience portfolio turnover
because it invests only in short-term money market instruments.
    
 
   
    A high rate of portfolio turnover involves corresponding greater expenses
than a lower rate. A Fund and its shareholders must bear such higher expenses.
High portfolio turnover also may result in the realization of substantial net
short-term capital gains.
    
 
   
    A significant increase in bond yields early in calendar year 1996 provided
an opportunity to restructure the Government Bond Fund. Bonds with high coupons
and short maturities and calls were sold with the proceeds invested in bonds
with similar coupons and longer maturities. Another opportunity to restructure
occurred in mid-calendar year 1998, when investors appeared to strongly prefer
Treasury securities over all other fixed income securities. Agency and Treasury
securities with lower yields and shorter maturities were sold and the proceeds
were invested in agency and corporate issues with higher yields and longer
maturities.

    Directors of the Company who are affiliated with SM&R receive no
compensation for attendance at Board or committee meetings. No officer receives
compensation from the Company. Officers and directors of the Company affiliated
with SM&R may, however, receive indirect compensation from the Company to the
extent the Company pays underwriting commissions and investment advisory and
service fees to SM&R. During the year ended August 31, 1998, the Company paid or
accrued approximately $[      ] to directors for fees and expenses in attending
meetings of the Board.
    
 
   
    Directors, officers, full-time employees, and other affiliated persons of
the Company, SM&R, or American National may purchase Class T shares of the
Government Bond and Tax Free Funds at net asset value per share without the
imposition of any sales charge. (For more information, see "Who Can Purchase
Class T Shares?" and "Waiver of Initial Sales Charge for Special Purchasers" in
the Prospectus for Class T shares.) The difference between the price at which
these shares are sold to public and the price at which these shares are sold to
directors and affiliated persons arises because SM&R does not pay commissions on
sales of shares to these types of purchasers.
    
 
   
                      POLICY REGARDING PERSONAL INVESTING
    
 
   
    The following policies have been made a part of the Company's Code of
Ethics.
    
 
   
    A portfolio manager must use extreme care to avoid even the appearance of a
conflict of interest in trading in any personal account (or an account in which
he has a beneficial interest). Accordingly, a portfolio manager may not trade in
(or otherwise acquire) any security for his personal account if that same
security is held in, or is being considered as a potential acquisition by, any
of the Funds. Any beneficial interest in a security held by a portfolio manager
must be sold at least 24 hours prior to any investment by the Funds. The
following exceptions apply: (1) Any beneficial interest in a
    
 
                                       24
<PAGE>
   
security owned at the time of employment may be held or traded at any time other
than within 24 hours of a trade in the Funds for the same or related security.
Dividends in that security may be re-invested in accordance with a formal plan
offered by the issuer; (2) Any beneficial interest in a security acquired by
devise or bequeath may be held or traded at any time other than within 24 hours
of a trade in the Funds for the same or related security; (3) Any beneficial
interest in a security issued by the Government or any Agency of the United
States, a State, or any political subdivision thereof may be traded or held; and
(4) Any beneficial interest in a security for which a written approval is first
obtained from the President & CEO may be traded or held.
    
 
   
            PERSONAL INVESTING BY OTHER SM&R OFFICERS AND EMPLOYEES
    
 
   
    Officers and employees of the Company other than portfolio managers may
trade in (or otherwise acquire) or hold any security for his own account (or an
account in which he has beneficial interest). However, the trade must not occur
within 24 hours of a trade in the Funds for the same or related security.
    
 
   
              CONTROL PERSONS AND PRINCIPAL HOLDERS OF SECURITIES
    
 
   
    As of December   , 1998, the officers and directors of the Company as a

Any person who owns directly or indirectly more than 25% of the outstanding
voting securities of the Company or a fund is presumed by the Investment Company
Act of 1940 to "control" the Company or the fund, and may be able to
significantly influence the outcome of any shareholder vote. For purposes of
voting on matters submitted to shareholders, any person who owns more than 50%
of the outstanding shares of the Company or a fund generally would be able to
cast the deciding vote. By virtue of their stock ownership, SM&R and American
National control the Company's operations, including the ability to make changes
in the fundamental investment objectives and restrictions of each fund of the
Company, as well as the ability to increase investment advisory fees,
notwithstanding other shareholders' votes to the contrary.

    Under the Administrative Agreement with the Company, SM&R has agreed to pay
(or to reimburse each Fund for) each Fund's expenses (including the advisory fee
and administrative service fee, if any, paid to SM&R, and any other fees
allocated to all classes of shares of a Fund based on average daily net assets,
but exclusive of interest, taxes, the Service Fee, the Distribution Fee,
commissions and other expenses incidental to portfolio transactions and any
other class-specific expenses) in excess of 1.25% per year of such Fund's (0.35%
for the Money Market Fund) average daily net assets.
    
 
   
FEE WAIVERS
    
 
   
    In order to improve the yield and total return of a Fund, SM&R may, from
time to time, voluntarily waive or reduce all or any portion of its advisory
fee, administrative fee and/or assume certain or all expenses of that Fund while
retaining its ability to be reimbursed for such fees prior to the end of the
fiscal year. SM&R may rescind fee waivers and/or reductions, other than those
stated in the Administrative Agreement, at any time without notice to investors.
SM&R has voluntarily agreed to waive the advisory fee for the Tax Free Fund and
reimburse expenses incurred by the Government Bond and Primary Funds to the
extent that total expenses exceed average daily net assets as follows: Primary
Fund--0.80% and the Government Bond Fund--1.00%.
    
 
   
    During the years ended August 31, 1998, 1997, and 1996, SM&R reimbursed the
Company a total of $[      ], $162,949, and $237,833, respectively for expenses
of the Funds in excess of the expense limitation and/or any undertaking then in
existence. SM&R reimbursed expenses for each Fund during these periods as
follows: $[      ], $15,547, and $43,795, respectively, for the Government Bond
Fund; $[      ], $73,202, and $107,943, respectively for the Tax Free Fund; and
$[      ], $74,200, and $86,095, respectively, for the Primary Fund. During
these periods, the Money Market Fund had not yet commenced operations.
    
 
                                       29
<PAGE>
   
    The administrative service fee is payable to SM&R whether or not the actual
expenses to SM&R for providing administrative services is more or less than the
amount of such fee. For the years ended August 31, 1998, 1997, and 1996, SM&R
received administrative service fees from the Company of $[      ], $169,811,
and $139,189, respectively. SM&R received administrative service fees for each
Fund during these periods as follows: $[      ], $56,616, and $53,063,
respectively, for the Government Bond Fund; $[      ], $50,224, and $22,940,
respectively for the Tax Free Fund; and $[      ], $176,167, and $63,186,
respectively, for the Primary Fund.
    
 
   
                PORTFOLIO TRANSACTIONS AND BROKERAGE ALLOCATION
    
 
   
    SM&R, which supervises the Company's investments, is responsible for
effecting portfolio transactions through eligible securities brokers and
dealers, subject to the general supervision of the Company's Board of Directors.
Investment decisions are made by an Investment Committee of SM&R, and orders are
placed by persons supervised by that committee.
    
 
   
    There is no arrangement or intention to place orders with any specific
broker or group of brokers. The paramount factors considered by SM&R in placing
orders are efficiency in the execution of orders and obtaining the most
favorable prices for the Company in both purchases and sales of portfolio
securities. In seeking the best prices and executions, purchases and sales of
securities which are not listed or traded on a securities exchange are generally
executed with a principal market maker acting as principal. SM&R continuously
evaluates the brokerage fees paid by each Fund to any affiliated person by
comparing such fees to those paid by other investment companies for similar
transactions as reported in various industry surveys.
    
 
   
    Whenever the primary consideration of best price and best execution is met
to the satisfaction of SM&R, the brokers and dealers selected will include those
who provide supplementary statistical and research services. Such research
services include advice as to the advisability of investing in, purchasing or
selling securities, as well as analyses and reports concerning securities,
economic factors and trends. Such services and information may be used by SM&R
in servicing any fund it manages. Not all of these services or information may
be used by SM&R in connection with the Company. While SM&R is able to fulfill
its obligation to the Company without such information, its expenses might be
materially increased if it had to obtain and assemble such information through
its staff. However, the value of such information is not determinable. SM&R also
uses such information when rendering investment advisory services to the SM&R
Equity Funds, Investment Accounts and to American National and its other
accounts.
    
 
   
    SM&R will authorize each Fund to pay an amount of commission for effecting a
securities transaction in excess of the amount of commission another
broker-dealer would have charged only if it determines in good faith that such
amount of commission is reasonable in relation to the value of the brokerage and
research services provided by such broker-dealer. Generally, the Funds pay
higher than the lowest commission rates available.
    
 
                                       30
<PAGE>
   
    During the years ended August 31, 1998, 1997, and 1996, the Company paid no
brokerage fees for transactions in portfolio securities. No brokerage
commissions have been paid during the three most recent fiscal years to: (i) any
broker that is an affiliated person of the Company or an affiliated person of
that person; or (ii) any broker an affiliated person of which is an affiliated
person of the Company or SM&R.
    
 
   
    Consistent with the Conduct Rules of the National Association of Securities
Dealers, and subject to seeking the best price and execution, the Company may
give consideration to sales of shares of the Company as a factor in the
selection of brokers and dealers to execute Company portfolio transactions.
    
 
   
    If purchases or sales of securities of the Fund and one or more other
investment companies or clients managed by SM&R are considered at or about the
same time, transactions in such securities will be allocated among the several
investment companies and clients in a manner deemed equitable to all by SM&R,
taking into account the respective sizes of the Fund and such other investment
companies and clients and the amount of securities to be purchased or sold.
    
 
   
    The Board has determined that such ability to effect simultaneous
transactions may be in the best interests of each Fund. It is recognized that in
some cases these practices could have a detrimental effect upon the price and
volume of securities being bought and sold by each Fund, while in other cases
these practices could produce better executions.
    
 
   
                           DESCRIPTION OF FUND SHARES
    
 
   
SHARES OF BENEFICIAL INTEREST
    
 
   
    The Company's authorized capital stock consists of six billion
(6,000,000,000) shares of common stock with a par value of $0.01 per share,
issuable in separate series. Currently four such series have been
established--the Government Bond Fund, the Tax Free Fund, the Primary Fund, and
the Money Market Fund. The Government Bond Fund and the Tax Free Fund (the
"Multi-Class Funds") are each divided into six Classes of shares of common stock
designated as:
    
 
   
    - Class T (existing shareholders and certain designated persons);
    
 
   
    - Class A (front-end load);
    
 
   
    - Class B (back-end load);
    
 
   
    - Class C (level load);
    
 
   
    - Class J (network);
    
 
   
    - Class Y (institutional shareholders).
    
 
   
    The Primary Fund and Money Market Fund do not have separate classes (that
is, each is a "Single-Class Fund").
    
 
   
    The Company designates its capital stock as shares of the Funds. Each Fund
is, for investment purposes, considered a separate investment fund. The shares
of each Fund,
    
 
                                       31
<PAGE>
   
when issued, will be fully paid and non-assessable, will have no conversion,
preemptive, or other subscription rights, and will be freely transferable and
redeemable. Each Fund bears its own liabilities and its proportionate share of
the general liabilities of the Company.
    
 
   
    Each share of capital stock represents an interest in the assets of a
particular Fund and has no interest in the assets of any other Fund. Shares of a
Fund are equal with respect to distributions from income and capital gains,
except as described below. In the event of liquidation, each share of a Fund is
entitled to an equal portion of all the assets of that Fund after all debts and
expenses have been paid.
    
 
   
    Each Class of shares of a Multi-Class Fund represents an interest in the
same portfolio of investments and each Class has the same rights as the other
Classes, except that each Class bears its own expenses and its proportionate
share of the general liabilities of that Fund. The net income attributable to
each Class and the dividends payable on the shares of that Class will be reduced
by the amount of the service and distribution (12b-1) fees of that Class and any
Class-specific expenses. Class B and Class C shares are subject to higher
distribution fees, which will cause such Classes to have a higher expense ratio
and pay lower dividends than the Class A shares.
    
 
                                       32
<PAGE>
   
    Each Fund bears its proportionate share of the Company's general expenses
not susceptible of direct allocation. Such general expenses include the
Company's organizational expenses, directors' fees and joint fidelity bonds,
which are pro-rated based on the relative amount of each fund's assets, and
prospectus and shareholder report expenses, which are pro-rated based on the
relative number of each fund's shareholders. Organizational expenses for the Tax
Free Fund and the Money Market Fund were paid by the adviser.
    
 
   
VOTING RIGHTS
    
 
   
    Within the respective Funds, all shares have equal voting, participation,
and liquidation rights, but do not have cumulative voting rights. With respect
to election of directors, non-cumulative voting means that the holders of more
than 50% of the shares voting for the election of directors can elect 100% of
the directors if they so choose, and in such event, holders of the remaining
shares will not be able to elect any directors.
    
 
   
    On certain matters, such as the election of directors, all shares of each
Fund vote together, with each share having one vote. On other matters affecting
a particular Fund, such as the Investment Advisory Contract or fundamental
investment policies, only shares of that Fund are entitled to vote, and a
majority of the shares of that Fund are required for approval of the proposal.
On matters affecting a particular Class of a Fund, only shares of that Class of
the Fund are entitled to vote, and a majority of the shares of that Class are
required for approval of the proposal.
    
 
   
INITIAL CAPITAL CONTRIBUTIONS
    
 
   
    Prior to the Company's offering of any shares to investors, SM&R provided
the Company with initial capital by purchasing 100,000 shares of the Primary
Fund at a purchase price of $1.00 per share and 10,000 shares of the Government
Bond Fund at a purchase price of $10.00 per share. In addition, SM&R purchased
an additional 190,000 shares of the Government Bond Fund at a purchase price of
$10.00 per share, and American National purchased 400,000 shares of the
Government Bond Fund at a price of $10.00 per share. Such additional shares of
the Government Bond Fund were acquired by SM&R and American National in
connection with the formation of the Company, were acquired for investment and
can be disposed of only by redemption.
    
 
   
    The Tax Free Fund initial capital was provided by SM&R through the purchase
of 10,000 shares at a price of $10.00 per share. In addition, SM&R purchased an
additional 90,000 shares and American National purchased 500,000 shares at a
price of $10.00 per share. These additional shares were acquired by SM&R and
American National in connection with the formation of the Fund for investment
and can only be disposed of by redemption.
    
 
   
    SM&R provided the initial capital to the Money Market Fund by purchasing
[      ] shares of that Fund at $1.00 per share.
    
 
                                       33
<PAGE>
   
    Both SM&R's and American National's shares will be redeemed only when
permitted by the 1940 Act and when the other assets of the Fund are large enough
that such redemption will not have a material adverse effect upon investment
performance.
    
 
   
                  PURCHASE, REDEMPTION, AND PRICING OF SHARES
    
 
   
    Certificates representing shares purchased are not ordinarily issued in an
effort to minimize the risk of loss or theft. Most investors do not choose to
receive certificates for their shares as this eliminates the problem of
safekeeping and facilitates redemptions and transfers. However, a confirmation
will be sent to the investor promptly after each share purchase. The investor
will have the same ownership rights with respect to shares purchased as if
certificates had been issued. Investors may receive a certificate representing
shares by making written request to SM&R. If a certificate is requested, it will
normally be forwarded to the investor within 14 days after receipt of the
request. SM&R reserves the right to charge a small administrative fee for
issuance of any certificates. Certificates will not be issued for fractional
shares (although fractional shares remain in your account on the books of each
Fund). Lost, stolen, or destroyed certificates cannot be replaced without first
obtaining a sufficient indemnity bond. The cost of such a bond is borne by the
investor and can be 2% or more of the current market value of the lost, stolen,
or destroyed certificate.
    
 
   
    All purchases must be in (or payable in) U.S. dollars. All checks must be
drawn in U.S. dollars on a U.S. bank. Investors will be subject to a service
charge on dishonored checks. The Company reserves the right to reject any order
for the purchase of its shares when in the judgment of management such rejection
is in the best interests of the Company.
    
 
   
DETERMINATION OF NET ASSET VALUE
    
 
   
    GOVERNMENT BOND FUND AND TAX FREE FUND.  The net asset value per share for
each Class of the Government Bond and Tax Free Funds is determined by adding the
market value of the portfolio securities and other assets of that Class
(including dividends accrued but not collected), subtracting liabilities of that
Class (including accrued expenses), and dividing the result by the number of
shares outstanding of the relevant Class. Net asset value is currently
determined as of 3:00 p.m. Central Time on each business day. Although the legal
rights of the Classes of a Fund are substantially identical, the different
expenses borne by each Class will result in different net asset values and
dividends for each Class.
    
 
   
    Expenses and fees of each such Fund, including the advisory fee and the
expense limitation reimbursement, if any, are accrued daily and taken into
account in determining net asset value. The portfolio securities of the Company
are valued as of the close of trading on each day when the New York Stock
Exchange is open for trading other than customary national business holidays and
SM&R's business holidays, as described in the Prospectuses. Securities listed on
national securities exchanges are valued at the last sales price on such day, or
if there is no sale, then at the closing bid price therefor on such day
    
 
                                       34
<PAGE>
   
on such exchange. The value of unlisted securities is determined on the basis of
the latest bid prices therefor on such day. Debt obligations that are issued or
guaranteed by the U.S. Government, its agencies, authorities, and
instrumentalities are valued on the basis of prices provided by an independent
pricing service. Prices provided by the pricing service may be determined
without exclusive reliance on quoted prices, and may reflect appropriate factors
such as yield, type of issue, coupon rate, maturity and seasoning differential.
Securities in corporate short-term notes are valued at cost plus amortized
discount, which approximates market value. If no quotations are available for a
security or other property, it is valued at fair value as determined in good
faith by the Board on a consistent basis.
    
 
   
    PRIMARY FUND.  The net asset value per share of the Primary Fund is
determined by adding the market value of its portfolio securities and other
assets, subtracting liabilities, and dividing the result by the number of such
Fund's shares outstanding. Expenses of the Primary Fund, if any, are accrued
daily and taken into account in determining the net asset value. The portfolio
securities of the Primary Fund are valued as of 3:00 p.m. Central Time on each
business day. Securities listed on national exchanges are valued at the last
sales price on such day, or if there is no sale, then at the closing bid price
therefor on such day on such exchange. The value of unlisted securities is
determined on the basis of the latest bid prices therefor on such day.
Securities in corporate short-term notes are valued at cost plus amortized
discount, which approximates market value. Debt securities with maturities in
excess of 60 days are valued on the basis of prices provided by an independent
pricing service or brokers. If no quotations are available for a security or
other property, it is valued at fair value as determined in good faith by the
Board of Directors of the Company on a consistent basis.
    
 
   
    Securities subject to floating or variable interest rates with demand
features in compliance with applicable Rules of the Securities and Exchange
Commission may have stated maturities in excess of one year.
    
 
   
    MONEY MARKET FUND.  The Money Market Fund values all of its securities using
the amortized cost valuation method, which does not take into account unrealized
capital gains or losses. This involves valuing an instrument at its cost and
thereafter assuming a constant amortization to maturity of any discount or
premium, regardless of the impact of fluctuating interest rates on the market
value of the instrument. The other Funds use the amortized cost method only for
valuing debt securities having maturities of 60 days or less.
    
 
   
    During periods of declining interest rates, the daily yield on shares of the
Money Market Fund may tend to be higher than a like computation made by funds
with identical investments utilizing a method of valuation based upon market
prices and estimates of market prices for all of its portfolio instruments.
Thus, if the use of amortized cost by the Money Market Fund results in a lower
aggregate portfolio value on a particular day, a prospective investor in the
Fund would be able to obtain a somewhat higher yield than would result from
investment in a fund with identical investments utilizing solely market
    
 
                                       35
<PAGE>
   
values, and existing investors in the Fund would receive less investment income.
The converse would apply in a period of rising interest rates.
    
 
   
    The valuation of the Money Market Fund's instruments based upon amortized
cost is subject to the Fund's adherence to certain conditions with respect to
its operation. The Fund must maintain a dollar-weighted average portfolio
maturity of 90 days or less, purchase instruments having a remaining maturity of
one year or less, and invest only in securities that the Board determines to be
of high quality with minimal credit risks.
    
 
   
    Pursuant to the rules of the Securities and Exchange Commission, the Money
Market Fund follows procedures established by the Board that are designed to
stabilize, to the extent reasonably possible, the Money Market Fund's net asset
value at $1.00 per share. There can be no assurance that the Money Market Fund
will at all times be to maintain a continuous $1.00 net asst value per share.
These procedures include a review of the extent of any deviation of net asset
value per share as a result of fluctuating interest rates, based on available
market rates, from the Fund's $1.00 per share amortized cost price per share.
Should that deviation exceed 1/2 of 1%, the Board will consider whether any
action shall be initiated to eliminate or reduce material dilution or other
unfair results to shareholders. Where the Board believes the extent of any
deviation from the Fund's $1.00 amortized cost price per share may result in
material dilution or other unfair results to investors or existing shareholders,
it shall cause the Money Market Fund to take such action as it deems appropriate
to eliminate or to reduce to extent reasonably practicable such dilution or
unfair results, which may include: redeeming of shares in kind; selling
portfolio instruments prior to maturity to realize capital gains or losses;
shortening the Fund's average maturity; or withholding dividends.
    
 
   
DETERMINATION OF OFFERING PRICE
    
 
   
    Shares of the Money Market Fund and the Primary Fund are offered at net
asset value without the imposition of any sales charge on purchases or
redemptions.
    
 
   
    Full and fractional shares of the Government Bond Fund and Tax Free Fund are
purchased at the offering price, which is the net asset value next determined
after receipt of a purchase plus any applicable sales charge. The sales charge
is a percentage of the net asset value per share and will vary as shown below.
Purchases received by SM&R at its office in Galveston, Texas prior to 3:00 p.m.,
Central Time, will be executed at the applicable offering price determined on
that day. Purchases received thereafter will be executed at the offering price
determined on the next business day.
    
 
   
    CLASS T SHARES (EXISTING SHAREHOLDERS).  The offering price of the Class T
Shares of the Government Bond Fund and Tax Free Fund is the net asset value per
share plus an initial sales charge of up to 4.5% of the public offering price.
For amounts invested over certain levels, or "breakpoints" (beginning at
$100,000), you pay reduced sales charges. Certain purchasers of Class T shares
may qualify for a reduction or waiver of initial sales charges, as set forth in
the chart below and under "Special Purchase Plans" below and "Sales Charge
Reductions and Waivers" in the Prospectuses. If you invest $500,000 or more in
Class T shares, there is no initial sales charge.

    CLASS A SHARES (FRONT-END LOAD).  Class A shares are subject to an initial
sales charge of up to 4.75% of the public offering price and an annual 12b-1 fee
of 0.25% of the average daily net assets of the Class A shares. For amounts
invested over certain levels, or "breakpoints" (beginning at $50,000), you pay
reduced sales charges. Certain purchasers of Class A shares may qualify for a
reduction or waiver of initial sales charges, as set forth in the chart below
and under "Special Purchase Plans" below and "Sales Charge Reductions and
Waivers" in the Prospectuses. If you invest $1 million or more in Class A
shares, there is no initial sales charge, but such shares will be subject to a
contingent deferred sales charge ("CDSC") of 1.00% of the offering price on
redemptions within 13 months of purchase.

CLASS B SHARES (BACK-END LOAD).
    
 
   
    An investor pays no initial sales charge upon the purchase of Class B
shares, but such shares are subject to a CDSC that declines from 3.00% to zero,
calculated as a percentage of the amount invested, imposed on certain
redemptions made within four years of purchase. Class B shares are subject to an
annual 12b-1 fee of 0.75% of the average daily net asset value of the Class B
shares.
    
 
   
    Class B shares are sold at net asset value subject to a contingent deferred
sales charge (expressed as a percentage of the offering price) shown in the
following table:

    If the net asset value of shares being redeemed has increased above the
initial purchase price, no CDSC is imposed on amounts attributable to such
increase in net asset value. No CDSC is assessed on shares derived from
reinvestment of dividends or capital gain distributions. The Company will
minimize any applicable CDSC payable by assuming that an investor (i) first
redeems Class B shares owned through reinvested dividends and capital gains
distributions, and (ii) next redeems Class B shares held the longest.
    
 
   
    Class B shares convert automatically to the appropriate number of Class A
shares of equal dollar value after the investor has owned the Class B shares for
eight (8) years. Dividends and other distributions paid to an investor in the
form of additional Class B shares also will convert to Class A shares on a
pro-rata basis. The conversion benefits shareholders because Class A shares are
not subject to an ongoing Distribution Fee. If an investor converts Class B
shares of a Multi-Class Fund for Class B shares of another fund managed by SM&R,
the purchase date of the original investment will be used to determine the
appropriate conversion date.
    
 
   
    CLASS C SHARES (LEVEL LOAD).  The Multi-Class Funds offer Class C shares at
their respective net asset value plus an initial sales charge of 1.00% of the
offering price. A contingent deferred sales charge of 1.00% is also assessed on
redemptions of Class C shares during the first thirteen months after purchase.
Class C shares are subject to an annual 12b-1 fee of 1.00% of the average daily
net asset value of the Class C shares.
    
 
   
    CLASS Y SHARES.  Class Y shares are no-load shares of the Multi-Class Funds
that are available to institutions and certain other investors, as described in
the Prospectus for the Class Y shares. Like the Single Class shares, Class Y
shares are offered at net asset value
    
 
                                       38
<PAGE>
   
without the imposition of any sales charge on purchases or redemptions or any
distribution and service ("12b-1") fees. Accordingly, the Offering Price for
Class Y shares of each Multi-Class Fund is that Class' net asset value.
    
 
   
    CLASS J SHARES.  Class J shares of the Multi-Class Funds are offered through
certain financial intermediaries (such as broker-dealers, investment advisers,
and mutual fund "marketplaces") that have distribution agreements with SM&R.
Like the Single Class shares, Class J shares are offered at net asset value
without the imposition of any sales charge on purchases or redemptions.
Accordingly, the Offering Price for Class J shares of each Multi-Class Fund is
that Class' net asset value. Class J shares are subject to an annual 12b-1 fee
of .75% of the average daily net asset value of the Class J shares.
    
 
   
REDUCTION AND/OR WAIVER OF INITIAL SALES CHARGES (CLASS A AND CLASS T SHARES)
    
 
   
    DISCOUNTS THROUGH CONCURRENT PURCHASES.  Investors may qualify for a reduced
sales charge on Class T shares or Class A shares. To qualify, the investor may
investors may combine concurrent purchases of Class T shares of a Multi-Class
Fund and the Class T shares of another Multi-Class Fund at the respective sales
charges applicable to each. Investors may likewise combine concurrent purchases
of Class A Shares of the Multi-Class Funds.
    
 
   
    Investors that are eligible to combine concurrent purchases to qualify for a
reduced sales charge include:
    
 
   
    (1) Any individual;
    
 
   
    (2) Any individual, his or her spouse, and trusts or custodial accounts for
       their minor children;
    
 
   
    (3) A trustee or fiduciary of a single trust estate or single fiduciary
       account.
    
 
   
    DISCOUNTS THROUGH A RIGHT OF ACCUMULATION.  If you already own Class T or
Class A shares of a fund managed by SM&R, you may be able to receive a discount
when you buy additional shares. The offering value of the shares you already own
may be "accumulated"--I.E., combined together with the offering value of the new
shares you plan to buy--to achieve quantities eligible for discount.
    
 
   
    LETTER OF INTENT.  You may qualify immediately for a reduced sales charge
the Letter of Intent section of the Account Application. Shareholders may
qualify for a reduced sales charge on purchases of Class T shares and Class A
shares of funds managed by SM&R by completing a Letter of Intent (See "Letter of
Intent" in the Prospectuses). A minimum initial investment equal to 10% of the
amount necessary for the applicable reduced sales charge is required when a
Letter of Intent is executed. Investments made under a Letter of Intent will
purchase shares at the total sales charge rate applicable to the specified total
investment. SM&R will hold in escrow from the initial investment shares equal to
5% of the amount of the total intended investment. Such escrow shares may not be
exchanged for or reinvested in shares of another fund and, subject to the
    
 
                                       39
<PAGE>
   
right of early cancellation described below, will not be released until the
amount purchased equals the commitment set forth in the Letter of Intent. If the
intended investment is not completed during the 13-month period, the difference
between the sales charge actually paid and the sales charge applicable to the
total of such purchases made will be deducted from the escrow shares if not paid
by the investor within twenty days after the date notice thereof has been mailed
to such investor.
    
 
   
    A Letter of Intent agreement can be canceled prior to the end of the
13-month period and escrow shares released to the investor if the investor pays
the difference between the sales charge paid and the sales charge applicable to
the amount actually invested and agrees that such Letter of Intent agreement is
canceled and no longer in effect.
    
 
   
    The offering value of the shares of funds managed by SM&R currently owned
may also be included in the aggregate amount of an investment covered by a
Letter of Intent.
    
 
   
    For example, if an investor owns shares of the Government Bond Fund, the Tax
Free Fund or shares of one or more SM&R Equity Funds currently valued at $80,000
and intends to invest $25,000 over the next thirteen months in the Government
Bond Fund and/or the Tax Free Fund, such investor may execute a Letter of Intent
and the entire $25,000 will purchase shares of either or all of such funds at
the reduced sales charge rate applicable to an investment of $100,000 or more. A
Letter of Intent does not represent a binding obligation on the part of the
investor to purchase or the Government Bond Fund or the Tax Free Fund to sell
the full amount of shares specified.
    
 
   
    WAIVER OF CLASS T INITIAL SALES CHARGE FOR SPECIAL PURCHASERS.  After
receipt of written request by SM&R, Class T shares of the Government Bond Fund
and the Tax Free Fund may be purchased by certain purchasers designated in the
Class T Prospectus at net asset value per share without the imposition of any
sales charge. The reduced sales charge rates set forth in the table above apply
to purchases of shares of the Government Bond Fund and the Tax Free Fund, either
singly or in combination with purchases of shares of the SM&R Equity Funds at
the respective sales charges applicable to each, made at one time by: (1) Any
individual; (2) Any individual, his or her spouse, and trusts or custodial
accounts for their minor children; (3) A trustee or fiduciary of a single trust
estate or single fiduciary account.
    
 
   
    Purchases in the Government Bond Fund will also receive a reduction in sales
charge pursuant to the rates set forth in the table above for purchases either
singly or in combination with purchases of shares of the SM&R Equity Funds at
the respective sales charges applicable to each, made at one time by: (1)
Tax-exempt organizations specified in Sections 501(c)(3) or (13) of the Internal
Revenue Code, or employees' trusts, pension, profit-sharing, or other employee
benefit plans qualified under Section 401 of the Internal Revenue Code; and (2)
Employees or employers on behalf of employees under any employee benefit plan
not qualified under Section 401 of the Internal Revenue Code.
    
 
                                       40
<PAGE>
   
    Furthermore, purchases by any "company" or employee benefit plans not
qualified under Section 401 of the Internal Revenue Code will qualify for the
above quantity discounts only if the Company will realize economies of scale in
sales effort and sales related expenses as a result of the employer's or the
plan's bearing the expense of any payroll deduction plan, making the Company's
prospectus available to individual investors or employees, forwarding
investments by such employees to the Company, and the like.
    
 
   
    The rates set forth above are applicable to single, lump sum purchases made
under the provisions of the preceding paragraphs 1, 2 and 3 and to qualified
investments under a "Letter of Intent" or under "Discounts Through a Right of
Accumulation" as described in the Prospectus for the Class T shares.
    
 
   
REDUCTION AND/OR WAIVER OF CONTINGENT DEFERRED SALES CHARGE (CLASS B SHARES)
    
 
   
    The CDSC will be waived on the following redemptions of Class B shares:
    
 
   
    (1) 10% FREE AMOUNT. The CDSC will be waived on redemptions of Class B
       shares of 10% (or less) per year of the amount otherwise subject to the
       CDSC (amounts not subject to a CDSC, such as appreciation and reinvested
       dividends, are withdrawn first).
    
 
   
    (2) DEATH OR DISABILITY. The CDSC will be waived on redemptions of Class B
       shares following the shareholder's death or disability, so long as:
    
 
   
       (a) SM&R is notified of such death or disability at the time of the
              redemption request and receives satisfactory evidence of such
              death or disability;
    
 
   
       (b) the redemptions are made within one year following death or initial
              determination of disability; and
    
 
   
       (c) the shares were held at the time of death or initial determination of
              disability.
    
 
   
        For purposes of this waiver, the death or disability must meet the
    definition in Section 72(m)(7) of the Internal Revenue Code (the "Code"). If
    the shares are held in a joint account, then all registered joint owners
    must be dead or disabled.
    
 
   
    (3) MINIMUM REQUIRED DISTRIBUTIONS. The CDSC will be waived on redemptions
       of Class B shares in connection with certain distributions from three
       types of qualified retirement plans: IRAs, custodial accounts maintained
       pursuant to Code Section 403(b), and plans qualified under Code Section
       401. To qualify for the waiver, the redemptions must result from one of
       the following:
    
 
   
       (a) required minimum distributions to plan participants or beneficiaries
              who are age 70 1/2 or older;
    
 
   
       (b) in kind transfers of assets where the participant or beneficiary
              notifies SM&R of such transfer before such transfer occurs;
    
 
                                       41
<PAGE>
   
       (c) tax-free rollovers or transfers of assets to another IRA, Section
              403(b) plan, or Section 401 plan invested in Class B shares of one
              or more funds managed by SM&R;
    
 
   
       (d) tax-free returns of excess contributions or returns of excess
              deferral amounts; and
    
 
   
       (e) distributions upon the death or disability (as defined in the Code)
              of the participant or beneficiary.
    
 
   
FUND AND CLASS EXPENSES
    
 
   
    Expenses that are directly attributable to a particular Class of shares
("Class Expenses") will be borne solely by that Class. Class expenses include:
(1) asset-based distribution fees and shareholder service fees; (2) transfer
agency fees attributable to a particular Class; (3) expenses related to
preparing, printing, mailing, and distributing materials such as shareholder
reports, prospectuses, and proxy statements to current shareholders of a
specific Class; (4) state and federal registration fees incurred by a specific
Class; (5) litigation and other legal expenses relating to a particular Class;
(6) directors' fees and expenses incurred as a result of issues relating solely
to a particular Class; (7) accounting, audit, and tax expenses relating to a
specific Class; (8) the expenses of administrative personnel and services
required to support the shareholders of a specific Class; and (9) fees and other
payments made to entities performing services for a particular Class, including
account maintenance, dividend disbursing, or subaccounting services.
    
 
   
    Class Expenses may be waived or reimbursed by SM&R, the Fund's investment
adviser and distributor. Investment advisory fees, custodial fees, and other
expenses relating to the management of the Company's assets shall not be
allocated on a class-specific basis. Income, realized and unrealized capital
gains and losses, and expenses that are not allocated to a specific Class shall
be allocated to each Class on the basis of the proportionate net assets of that
Class in relation to the net assets of the Multi-Class Fund.
    
 
   
    All direct sales expenses for the Primary Fund and the Money Market Fund,
including the cost of prospectuses for prospective shareholders, are paid by
SM&R, and no sales expense is borne by those Funds.
    
 
   
                  SHAREHOLDER SERVICING AND DISTRIBUTION PLAN
    
 
   
    The Company adopted a Distribution and Shareholder Servicing Plan (the
"12b-1 Plan") pursuant to Rule 12b-1 under the 1940 Act for the Class A, Class
B, Class C, and Class J shares of the Government Bond Fund and the Tax Free Fund
(as defined above, the "Multi-Class Funds"). The 12b-1 Plan provides that SM&R
will provide distribution and/or shareholder services to the Class A, Class B,
Class C, and Class J shares of the Multi-Class Funds (the "12b-1 Classes").
    
 
                                       42
<PAGE>
   
    For each 12b-1 Class and regardless of actual expenses, SM&R is entitled to
receive a Distribution Fee and/or Service Fee, as applicable, computed as an
annual percentage of the value of the average daily net assets of the
Multi-Class Fund attributable to that Class, as follows:

(1) The Distribution Fee and/or Service Fee, as applicable, to be paid under the
    12b-1 Plan will be calculated daily (as a percentage of average daily net
    assets) and paid periodically.
    
 
   
    The purpose of the Distribution Fee is to compensate SM&R, or enable SM&R to
compensate other persons, including any distributor of shares of the 12b-1
Classes, for services that are primarily intended to result in or primarily
attributable to the sale of the 12b-1 Classes ("Selling Services"). The purpose
of the Service Fee is to compensate SM&R, or enable SM&R to compensate other
persons, for providing ongoing servicing to shareholders of the Funds
("Shareholder Services").
    
 
   
    "Selling Services" include the training and supervision of sales personnel;
advertising, marketing, and other promotional expenses, including the costs of
preparing and printing sales literature; printing prospectuses and statements of
additional information and distributing them to prospective investors in 12b-1
Classes; and distributing shares of the 12b-1 Classes. Payments for Selling
Services may include payment for overhead and other office expenses that are
related to the distribution of the 12b-1 Classes. SM&R also may reimburse the
expenses of persons who provide support services in connection with the
distribution of the 12b-1 Classes, and may make payments to financial
intermediaries that sell shares of the 12b-1 Classes. "Shareholder Services"
include all forms of shareholder liaison services that SM&R deems appropriate,
including maintaining shareholder accounts, providing shareholder liaison
services, responding to customer inquiries, and providing shareholders with
information on their investments and about the 12b-1 Classes.
    
 
   
    The 12b-1 Plan, and any related agreement, continues in effect with respect
to a 12b-1 Class only if such continuance is specifically approved at least
annually by either the Board or the shareholders of that 12b-1 Class and, in
either case, by a majority vote of those directors who are not interested
persons of the Fund and who have no direct or indirect financial interest in the
operation of this Plan or in such agreement (the "Independent Directors"), cast
in person at a meeting called for the purpose of voting on
    
 
                                       43
<PAGE>
   
this Plan and/or the related agreement. The 12b-1 Plan may be terminated with
respect to any 12b-1 Class at any time, by vote of a majority of the Independent
Directors or by a vote of a majority of the outstanding voting securities of the
relevant Class.
    
 
   
    Any distribution and shareholder services agreement related to the 12b-1
Plan terminates automatically upon its assignment. Moreover, with respect to
each 12b-1 Classof a Multi-Class Fund, any distribution and shareholder services
agreement related to that 12b-1 Class may be terminated at any time, without the
payment of any penalty, (1) by the Board or by a vote of the 12b-1 Class'
outstanding shareholders, on 60 days written notice to SM&R, or (2) by SM&R, on
60 days written notice to the Company.
    
 
   
    The 12b-1 Plan provides that it may not be amended with respect to any 12b-1
Class of a Multi-Class Fund to increase materially the amount of the fees
described in such Plan without approval of the shareholders of the relevant
Class. All material amendments to the Plan also must be approved by the Board in
the manner described above and in the 12b-1 Plan.
    
 
   
    In each year during which this Plan remains in effect with respect to a
12b-1 Class, SM&R (and any other person authorized to direct the disposition of
monies paid or payable by the relevant Fund pursuant to the Plan or any related
agreement) will prepare and furnish to the Board, and the Board will review, at
least quarterly, written reports complying with the requirements of Rule 12b-1,
which set out the amounts expended under this Plan and the purposes for which
those expenditures were made. The obligations of the Company and each Fund under
the 12b-1 Plan will not be binding upon any of the directors, shareholders,
nominees, officers, employees or agents, whether past, present or future, of the
Company, individually, but are binding only upon the assets and property of the
Company and the relevant Funds or Funds, as provided in the Company's Articles
of Incorporation.
    
 
   
                             SPECIAL PURCHASE PLANS
    
 
   
SYSTEMATIC INVESTMENT PLAN AND ELECTRONIC TRANSFER SERVICE
    
 
   
    All Funds provide a convenient, voluntary method of purchasing their shares
through "Systematic Investment Plan and Electronic Transfer Service" (a "Plan"
or "Plans"). The principal purposes of such Plans are to encourage thrift by
enabling investors to make regular purchases in amounts less than normally
required, and, in the case of the Government Bond Fund and the Tax Free Fund, to
employ the principle of dollar cost averaging described below. INVESTORS SHOULD
BE AWARE THAT ANY APPLICABLE SALES CHARGE WILL APPLY TO PURCHASES MADE THROUGH A
PLAN.
    
 
   
    By acquiring shares of the Government Bond Fund and the Tax Free Fund on a
regular basis pursuant to a Plan, or investing regularly on any other systematic
plan, the investor takes advantage of the principle of Dollar Cost Averaging.
Under Dollar Cost Averaging, if a constant amount is invested at regular
intervals at varying price levels, the average cost of all the shares will be
lower than the average of the price levels. This is
    
 
                                       44
<PAGE>
   
because the same fixed number of dollars buys more shares when price levels are
low and fewer shares when price levels are high. It is essential that the
investor consider his or her financial ability to continue this investment
program during times of market decline as well as market rise. The principle of
Dollar Cost averaging will not protect against loss in a declining market, as a
loss will result if the Plan is discontinued when the market value is less than
cost.
    
 
   
    A Plan may be opened by indicating an intention to invest $20 or more (per
individual) in the Government Bond Fund or the Tax Free Fund or $100 or more in
the Primary Fund or Money Market Fund monthly for at least one year. The
investor will receive a confirmation showing the number of shares purchased,
purchase price, and subsequent new balance of shares accumulated.
    
 
   
    An investor has no obligation to invest regularly or to continue
participating in a Plan, which may be terminated by the investor at any time
without penalty. Under a Plan, any distributions of income and realized capital
gains will be reinvested in additional shares at net asset value unless a
shareholder instructs SM&R in writing to pay them in cash. SM&R reserves the
right to increase or decrease the amount required to open and continue the Plan,
and to terminate any shareholder's right to participate in the Plan if after one
year the value of the amount invested is less than $100 in the Government Bond
Fund or the Tax Free Fund or $1,000 in the Primary Fund or Money Market Fund.
    
 
   
GROUP SYSTEMATIC INVESTMENT PLAN
    
 
   
    A Group Systematic Investment Plan is available for purchases of Class A,
Class B, Class C, or Class J shares. This Plan provides employers and employees
with a convenient means for purchasing shares of the Company under various types
of employee benefit and thrift plans, including payroll deduction and bonus
incentive plans. The plan may be started with an initial cash investment of $100
($20 per individual) in the Government Bond Fund or the Tax Free Fund or $1,000
in the Primary Fund or Money Market Fund for a group consisting of five or more
participants. The shares purchased by each participant under the Plan will be
credited to a separate account in the name of each investor in which all
dividends and capital gains will be reinvested in additional shares of the
applicable Fund at net asset value (plus a sales charge, if applicable). Such
reinvestments will be made at the start of business on the day following the
record date for such dividends and capital gains distributions. To keep his or
her account open, subsequent payments in the amount of $20 must be made into
each participant's account. If the group is reduced to less than five
participants, the minimums set forth under "Systematic Investment Plan and
Electronic Transfer Service" shall apply. The plan may be terminated by SM&R or
the shareholder at any time upon sixty (60) days' prior written notice.
    
 
   
EXCHANGE PRIVILEGE
    
 
   
    Exchanges shall be permitted, without charge, between each class of Shares
of a Fund and the corresponding class of another fund managed by SM&R on terms
    
 
                                       45
<PAGE>
   
described in the Prospectuses. Investors also may exchange shares of a class of
a Multi-Class Fund for shares of a Single-Class Fund, and visa-versa, and may
exchange shares of one class of a Multi-Class Fund for shares of another class
of that Fund. An investor exchanging shares must meet any minimum investment
requirement for any shares the investor wishes to acquire, and must pay any
applicable sales charge.
    
 
   
    Investors may acquire, through an exchange, shares of a class with a CDSC.
For purposes of determining any CDSC an investor must pay if the investor
redeems those acquired shares, the length of time such acquired shares have been
held will be calculated from the date that the investor initially purchased
shares in the relevant fund, rather from the date the investor exchanged those
shares for the shares subject to a CDSC. In determining the applicability of any
CDSC, it will be assumed that a redemption is made first of shares representing
capital appreciation, next of shares representing the reinvestment of dividends
and capital gain distributions and finally other shares held by the shareholders
for the longest period of dividend and capital gain distribution reinvestments
in such other funds. For Federal income tax purposes, the amount of the CDSC
will reduce the gain or increase the loss, as the case may be, on the amount
realized on redemption.
    
 
   
    Shares of any fund held in escrow under a Letter of Intent are not eligible
for the exchange privilege. Such shares will not be released from escrow until
the balance invested during the period specified in the Letter of Intent equals
or exceeds the amount required to be invested under the Letter of Intent or the
shareholder requests, in writing, that the Letter of Intent be canceled and pays
any adjustments in sales charge. After release from escrow, shares may be
exchanged, provided all other applicable conditions are met.
    
 
   
    The exchange privilege does not give an investor the option or right to
purchase securities, but is a revocable privilege permitted under the present
policies of each of the Funds. SM&R reserves the right to restrict the frequency
of or otherwise modify, condition, terminate or impose additional charges upon
the exchange privilege. ANY GAIN OR LOSS REALIZED ON AN EXCHANGE OR RE-EXCHANGE
MAY BE RECOGNIZED FOR FEDERAL AND STATE INCOME TAX PURPOSES. YOU SHOULD CONSULT
YOUR TAX ADVISOR FOR THE TAX TREATMENT AND EFFECT OF EXCHANGES.
    
 
   
    The minimum number of shares of a Fund that may be exchanged is the number
of shares of the that Fund that have a net asset value on the date of such
exchange that is equal to the minimum initial or subsequent investment, as the
case may be, of the Fund or SM&R Equity Funds into which the exchange is being
made.

                                   REDEMPTION
    
 
   
    Any shareholder may redeem all or any part of his shares by submitting a
written request to SM&R as the Company's agent for such purpose. Such requests
must be duly executed by each registered owner, must be accompanied by
certificates endorsed for transfer (if certificates have been issued), and must
contain a signature guarantee. The signature guarantee carries with it certain
statutory warranties relied upon by the transfer agent. This guarantee is
designed to protect the investor, the funds, SM&R, and its representatives
through the signature verification of each investor wishing to redeem or
exchange shares.
    
 
   
    Signatures may be guaranteed by an "eligible guarantor institution" as
defined in rules adopted by the Securities and Exchange Commission. Eligible
guarantor institutions generally include banks, brokers, dealers, municipal
securities dealers or brokers, government securities dealers or brokers, credit
unions, national securities exchanges, registered securities associations and
institutions that participate in the Securities Transfer Agent Medallion Program
("STAMP") or other recognized signature guarantee medallion program or an SM&R
representative who has executed an agreement and received authorization from
SM&R. WITNESSING OR NOTARIZATION IS NOT SUFFICIENT.
    
 
   
    No signature guarantees are required on the written request for redemption
by a shareholder of record when payment is to be made to such shareholder of
record at such shareholder's address of record and the value of the shares
redeemed is $25,000 or less. In all other cases the signatures on the request
for redemption, as well as on certificates being tendered, must be guaranteed.
On all redemption requests for joint accounts, the signatures of all joint
owners are required. Redemptions may also be requested by telephone, see "HOW TO
REDEEM" in the Prospectuses. Corporations, executors, divorced persons,
administrators, trustees or guardians will be required to submit further
documentation. Any applicable CDSC must be paid upon redemption.
    
 
   
    Shares are redeemed at the net asset value per share next computed after the
request and certificates, if any, are received in "Proper Form" as set forth
above. Any applicable CDSC must be paid at the time of redemption. (See
"Redeeming Shares" in the Prospectuses). A shareholder may receive more or less
than he paid for his shares, depending on the prevailing market value of the
portfolio value of the Fund being redeemed and the applicable CDSC.
    
 
   
    Redemption checks are delivered as soon as practicable and normally will be
sent to the investor within seven days following the date on which redemption is
made.
    
 
   
    At various times the Company may be requested to redeem shares for which it
has not yet received good payment for prior purchases of Company shares.
Accordingly, proceeds of the Company will not be paid until good payment has
been received which could be as much as fifteen business days after the
purchase, or until SM&R can verify that good payment (for example, cash or
certified check on a United States bank) has been, or will be, collected for the
purchase of such shares.
    
 
                                       47

    The right of redemption is subject to suspension and payment therefor
postponed during any period when the New York Stock Exchange is closed other
than customary weekend or holiday closings, or during which trading on such
Exchange is restricted; for any period during which an emergency exists, as a
result of which disposal by the Company of its securities is not reasonably
practicable or it is not reasonably practicable for the Company to fairly
determine the value of its net assets; or for such other periods as the
Commission has by order permitted such suspension for the protection of the
Company's security holders.
    
 
   
    The Company has made an election under the 1940 Act to pay in cash all
requests for redemption by any shareholder of record, limited in amount with
respect to each shareholder during any ninety-day period to the lesser of (i)
$250,000 or (ii) 1% of the net asset value of the Company at the beginning of
such period. The Company may pay the redemption price, if any, in excess of the
amounts described above in whole or in part in portfolio securities, at the
market value thereof determined as of the close of business next following
receipt of the request in proper form, if deemed advisable by the Board of
Directors. In such case a shareholder would incur brokerage costs if he sold the
securities received.
    
 
   
                                     TAXES
    
 
   
ELECTION TO BE TAXED AS A REGULATED INVESTMENT COMPANY
    
 
   
    Each fund is treated as a separate entity for federal income tax purposes.
The Company has elected to be treated as a regulated investment company under
Subchapter M of the Internal Revenue Code. The Company intends to distribute all
of its net investment income and net realized capital gains to shareholders in a
timely manner. Therefore, it is not expected that the Company will be required
to pay federal income taxes.
    
 
   
    In order to qualify as a regulated investment company, each Fund of the
Company must meet several requirements. These requirements include the
following: (1) at least 90% of the Fund's gross income must be derived from
dividends, interest, payments with respect to securities loans, gains from the
sale or disposition of stock, securities or foreign currencies or other income
derived in connection with the Fund's investment business and (2) at the close
of each quarter of the Fund's taxable year, (a) at least 50% of the value of the
Fund's assets must consist of cash, United States Government securities,
securities of other regulated investment companies and other securities (limited
generally with respect to any one issuer to not more than 5% of the total assets
of the Fund and not more than 10% of the outstanding voting securities of such
issuer) and (b) not more than 25% of the value of the Fund's assets may be
invested in the securities of any issuer (other than United States Government
Securities or securities of other regulated investment companies) or of two or
more issuers which the Fund controls and which are determined to be engaged in
similar or related trades or businesses.
    
 
                                       48
<PAGE>
   
    In addition, each Fund must distribute to its shareholders at least 90% of
its net investment income and net tax-exempt income for each of its taxable
years. If a Fund fails to qualify as a regulated investment company, the Fund
will be subject to federal, and possibly state, corporate taxes on its taxable
income and gains, and distributions to its shareholders will be taxed as
ordinary dividend income to the extent of such Fund's available earnings and
profits.
    
 
   
EXCISE TAX
    
 
   
    In order to avoid federal excise taxes, each Fund is required to distribute
to its shareholders at least 98% of its taxable ordinary income earned during
the calendar year and 98% of its capital gain net income earned during the
twelve month period ending on October 31 (in addition to undistributed amounts
from the prior year). The Funds intend to declare and pay sufficient dividends
in a manner that will comply with such distribution requirements but can give no
assurances that their distributions will be sufficient to eliminate all such
excise taxes.
    
 
   
DISTRIBUTIONS OF INVESTMENT INCOME AND CAPITAL GAINS
    
 
   
    For federal income tax purposes, any income dividends derived from taxable
investments which the shareholder receives from a fund, as well as any
distributions derived from net short-term capital gains, are treated as ordinary
income whether the shareholder has elected to receive them in cash or in
additional shares. Distributions derived from net long-term capital gains will
be taxable as long-term capital gains regardless of the length of time the
shareholder has owned such fund's shares and regardless of whether such
distributions are received in cash or in additional shares. In determining the
amount of capital gains, if any, available for distribution, net capital gains
are offset against available net capital losses, if any, carried forward from
previous years.
    
 
   
    Distributions which are declared in October, November, or December and paid
to shareholders in January of the following year will be treated for tax
purposes as if they had been received by the shareholders on December 31 of the
year in which they were declared.
    
 
   
    At the end of each calendar year, the Company will advise shareholders about
the tax status of all distributions made during each taxable year, including the
portion of the dividends which comprise taxable income, exempt income and
interest income that is a tax preference item under the alternative minimum tax.
Shareholders should consult a tax advisor about the application of state and
local tax laws to these distributions and redemption proceeds received from the
Company.
    
 
   
    Many states grant tax-free status to dividends paid to shareholders of
mutual funds from interest income earned by the fund from direct obligations of
the U.S. Government, subject in some states to minimum investment requirements
that must be met within the fund.
    
 
                                       49
<PAGE>
   
    Dividends paid by the Tax Free Fund that are derived from interest earned on
qualifying tax-exempt obligations are expected to be "exempt-interest" dividends
that shareholders may exclude from their gross income for federal income tax
purposes if the fund satisfies certain quarterly asset percentage requirements.
To the extent that the Tax Free Fund invests in bonds, the interest on which is
a specific tax preference item for federal income tax purposes ("AMT-Subject
Bonds"), any exempt-interest dividends derived from interest on AMT-Subject
bonds will be a specific tax preference item for purposes of the federal
individual and corporate alternative minimum taxes. All exempt-interest
dividends will be a component of the "current earnings" adjustment item for
purposes of the federal corporate alternative minimum income tax. Current
federal tax law limits the types and volume of securities qualifying for the
federal income tax exemption of interest and may also affect the availability of
municipal obligations for investment by the fund and the value of the fund's
portfolio.
    
 
   
    Shareholders who are not U.S. persons for purposes of federal income
taxation should consult with their financial or tax advisors regarding the
applicability of U.S. withholding taxes to distributions received by them from
the Company.
    
 
   
REDEMPTION OF FUND SHARES
    
 
   
    Redemptions and exchanges of fund shares are taxable transactions for
federal and state income tax purposes. The tax law generally requires that
shareholders recognize a gain or loss in an amount equal to the difference
between the amount received by the shareholder and the shareholder's tax basis.
If the fund shares are held as a capital asset, the shareholder will realize
capital gain or loss and if the shares have been held for more than one year at
the time of the redemption or exchange, the shareholder will realize long term
gain or loss for federal income tax purposes. Any loss incurred on the
redemption or exchange of shares held for six months or less will be treated as
a long term capital loss to the extent of any long-term capital gains
distributed to the shareholder on those shares. In addition, all or a portion of
any loss realized upon the redemption of fund shares will be disallowed to the
extent the shareholder buys other shares in the fund (through reinvestment of
dividends or otherwise) within 30 days before or after the share redemption.
(Any loss disallowed under this rule will be added to the shareholder's tax
basis in the new fund shares acquired during such period.)
    
 
   
    Shareholders of the Tax Free Fund should be careful about redeeming shares
immediately prior to the record date of an exempt-interest dividend because the
redemption may cause the shareholder to realize a taxable gain even though a
portion of the redemption proceeds may represent a pro rata share of tax exempt
interest earned by the fund. In addition, a loss on the sale or redemption of
shares held by the shareholder of the Tax Free Fund for six months or less will
be disallowed to the extent of any exempt-interest dividend received by the
shareholder with respect to those shares.

<PAGE>
   
BACKUP WITHHOLDING
    
 
   
    The Company may be required to report to the Internal Revenue Service
("IRS") any taxable dividends or other reportable payment (including share
redemption proceeds) and withhold 31% of any such payments made to individuals
and other non-exempt shareholders who have not provided a correct taxpayer
identification number and made certain required certifications that appear in
the account application. A shareholder may also be subject to backup withholding
if the IRS or a broker notifies the Company that the number furnished by the
shareholder is incorrect or that the shareholder is subject to backup
withholding for previous under-reporting of interest or dividend income.
    
 
   
NON-U.S. INVESTORS
    
 
   
    Ordinary dividends generally will be subject to U.S. income tax withholding.
The non-U.S. investor's home country may also tax ordinary dividends, capital
gain distributions and gains arising from redemptions and exchanges of fund
shares. Fund shares held by the estate of a non-U.S. investor may be subject to
U.S. estate tax. Non-U.S. investors may wish to contact their tax advisors to
determine the U.S. and non-U.S. tax consequences of an investment in the Funds.
    
 
   
IMPORTANT: The Company reserves the right to (1) refuse to open an account for
any person failing to provide a taxpayer identification number, certified as
correct and (2) close an account by redeeming its shares in full, at the then
current net asset value, upon receipt of notice from the IRS that the taxpayer
identification number certified as correct by the shareholder is in fact
incorrect.
    
 
   
                           SYSTEMATIC WITHDRAWAL PLAN
    
 
   
    As described in the Prospectuses under "Systematic Withdrawal Plan," the
Fund have a Systematic Withdrawal Plan pursuant to which shareholders having an
account value of $5,000 or more to automatically withdraw a minimum of $50
monthly or quarterly. It may not be advisable for shareholders to maintain a
Withdrawal Account while concurrently purchasing shares of the Government Bond
Fund or the Tax Free Fund because of the sales charge or CDSC (as applicable)
involved in additional purchases. A shareholder should carefully consider such
purchases and contact his or her financial adviser regarding their advisability.
    
 
   
    A Systematic Withdrawal Plan provides for regular monthly or quarterly
payments to the account investor or his designee through redemption of a portion
of the shares held in the account. Some portion of each withdrawal may be
taxable gain or loss to the account investor at the time of the withdrawal, the
amount of the gain or loss being determined by the investment in the Fund's
shares. The minimum, though not necessarily recommended, withdrawal amount is
$50. Shares sufficient to provide the designated withdrawal payment are redeemed
each month or quarterly on the 20th, or the next succeeding business day, and
checks are mailed to reach the investor on or about the 1st
    
 
                                       51
<PAGE>
   
of the following month. All income dividends and capital gains distributions are
automatically reinvested at net asset value, without sales charge. Since each
withdrawal check represents proceeds from the sale of sufficient shares equal to
the withdrawal, there can be a reduction of invested capital, particularly in a
declining market. If redemptions are consistently in excess of shares added
through reinvestment of distributions, the withdrawals will ultimately exhaust
the capital.
    
 
   
    The shareholder may designate withdrawal payments for a fixed dollar amount,
as stated in the preceding paragraph, or a variable dollar amount based on (1)
redemption of a fixed number of shares at monthly or quarterly intervals, or (2)
redemption of a specified and increasing fraction of shares held at monthly or
quarterly intervals. To illustrate the latter option, if an investor wanted
quarterly payments for a ten-year period, the first withdrawal payment would be
the proceeds from redemption of 1/40th of the shares held in the account. The
second payment would be 1/39th of the remaining shares; the third payment would
be 1/38th of the remaining shares, etc. Under this option, all shares would be
redeemed over the ten-year period, and the payment amount would vary each
quarter, depending upon the number of shares redeemed and the redemption price.
    
 
   
    No charge is made for a non-qualified Systematic Withdrawal Plan, and the
account investor may change the option or payment amount at any time upon
written request received by SM&R no later than the month prior to the month of a
scheduled redemption for a withdrawal payment. A Systematic Withdrawal Plan may
also be terminated at any time by the account investor or the Fund without
penalty.
    
 
   
    Occasionally certain limited types of qualified retirement plans are
involved in making investments and withdrawals during the same year. Under such
an arrangement, it is possible for the plan to be, in effect, charged duplicate
sales charges. In order to eliminate this possibility, each Fund of the Company
will permit additional investments, without sales charge, equal to all sums
withdrawn, providing the additional investments are made during the next twelve
months following the withdrawal or redemption, and providing that all funds
withdrawn were for the specific purpose of satisfying plan benefits of
participants who have retired, become disabled or left the plan. Furthermore,
for a qualified plan to qualify under this provision, the plan must include at
least one participant who is a non-owner employee. The Company and SM&R
discourage shareholders from maintaining a withdrawal account while concurrently
and regularly purchasing shares of the Company although such practice is not
prohibited.
    
 
   
                                THE UNDERWRITER
    
 
   
    SM&R serves as principal underwriter of the shares of all Funds of the
Company pursuant to an Underwriting Agreement dated July 1, 1993, as amended on
[             ] (the "Underwriting Agreement"). Such Underwriting Agreement
provides that it shall continue in effect only so long as such continuance is
specifically approved at least annually by the Board of Directors of the Company
or by vote of a majority of the outstanding voting securities of a Fund and, in
either case, by the specific
    
 
                                       52
<PAGE>
   
approval of a majority of directors who are not parties to such agreement or not
"interested" persons (as defined in the 1940 Act) of any such parties, cast in
person at a meeting called for the purpose of voting on such approval. The
Underwriting Agreement was approved by the Board of Directors of the Company in
accordance with such procedures at a meeting held on [             ]. The
Underwriting Agreement may be terminated without penalty by vote of the Board of
Directors or by vote of the holders of a majority of the outstanding voting
securities of the Company, or by SM&R, upon sixty (60) days' written notice and
will automatically terminate if assigned (as provided in the 1940 Act).
    
 
   
    As principal underwriter, SM&R continuously offers and sells shares of each
Fund of the Company through its own sales representatives and broker-dealers. As
compensation for such services, SM&R receives the sales charge, which is the
difference between the offering price at which shares are issued and the net
asset value thereof.
    
 
   
    Broker-dealers or other securities dealers that have entered into selling
agreements with SM&R may receive compensation from SM&R or an affiliated company
in connection with selling shares of the SM&R Family of Funds. Compensation may
include financial assistance for conferences, shareholder services, automation,
sales and training programs, or promotional activities. Registered
representatives and their families may be paid for travel expenses, including
lodging, in connection with business meetings or seminars. In some cases, this
compensation may only be available to securities dealers whose representatives
have sold or are expected to sell significant amounts of shares. Securities
dealers may not use certain sales to qualify for this compensation if prohibited
by the laws of any state or self-regulatory agency, such as the National
Association of Securities Dealers, Inc.
    
 
   
    The sales charge allowance to broker-dealers, ranges from a maximum of 4.7%
to a minimum of 2.6% of the net amount invested, and from a maximum of 4.0% to a
minimum of 2.0% of the public offering price. For certain large purchases, SM&R
intends to pay its representatives and broker-dealers from its own profits and
resources. The amount (expressed as a per annum percentage of the amount
invested) which SM&R might pay such representatives and broker-dealers is as
follows for Class A shares of the Government Income and Tax Free Funds,
respectively: Year 1 - [  ]% and [  ]%; Year 2 - [  ]% and [  ]%; and Year 3 and
subsequent years, [    ]% (for each fund). For Class T shares of the Government
Income and Tax Free Funds, SM&R may pay representatives and broker-dealers as
follows: Year 1 - [  ]% and [  ]%; Year 2 - [  ]% and [  ]%; and Year 3 and
subsequent years, [    ]% (for each fund).
    
 
   
    The aggregate amount of sales charge received by SM&R from the sale of
Company shares for the years ended August 31, 1998, 1997, and 1996 was $[    ],
$29,337, and $92,706. The amount of sales charge retained by SM&R from the sale
of Company shares for the years ended August 31, 1998, 1997, and 1996 was

                       AUDITORS AND FINANCIAL STATEMENTS
    
 
   
    Tait, Weller & Baker ("TWB"), 8 Penn Center, Philadelphia, PA 19103, served
as the Company's independent auditors for the year ending August 31, 1998. Prior
to the year ending August 31, 1998, the Company's financial statements were
audited by KPMG Peat Marwick LLP, 700 Louisiana, Houston, Texas 77002 ("KPMG").
    
 
   
    Due to a concern over a potential conflict of interest, KPMG resigned as
auditors to the Company. The Board appointed TWB to serve as the independent
auditors to the Company for the year ended August 31, 1998. Shareholders of the
Company ratified the selection of TWB at a meeting of the Shareholders held on
May 28, 1998. For the year ended December 31, 1997, and up to the date of
resignation of KPMG, there were no disagreements with KPMG on any matter of
accounting principles or practices, financial statement disclosure or auditing
scope or procedure which, if not resolved to the satisfaction of KPMG, would
have caused it to make reference to the subject matter of the disagreement in
connection with its report. The independent auditors' report on the 1997
financial statements did not contain an adverse opinion or a disclaimer of
opinion, and was not qualified or modified as to uncertainty, audit scope or
accounting principles. Each of TWB and KPMG has advised the Company that neither
it nor any present member or associate of the relevant firm has any financial
interest, direct or indirect, in the Company.

    The Company's Schedule of Investments and audited financial statements for
the year ended August 31, 1998, and the Independent Auditors' Report of TWB
dated October   , 1998, are included herein.
    
 
   
                        PERFORMANCE AND ADVERTISING DATA
    
 
   
    Quotations of performance may from time to time be used in advertisements,
sales literature, shareholder reports or other communications to shareholders or
prospective investors. Each Fund's yield and total return fluctuate in response
to market conditions and other factors. Investment return and principal value
will fluctuate, and shares, when redeemed, may be worth more or less than their
original cost. There can be no assurance that the Money Market Fund will be able
to maintain a stable net asset value of $1.00 per share.
    
 
   
    Each Fund's performance may be quoted in advertising in terms of yield or
total return. All advertisements will disclose the maximum sales charge to which
investments in shares of that Fund may be subject. If any advertised performance
data does not reflect the maximum sales charge (if any), such advertisement will
disclose that the sales charge has not been deducted in computing the
performance data, and that, if reflected, the maximum sales charge would reduce
the performance quoted. An investor should keep in mind when reviewing
performance that past performance of a fund is not indicative of future results,
but is an indication of the return to the investor only for the limited
historical period.
    
 
   
    With respect to those categories of investors who are permitted to purchase
shares of a Fund at net asset value, sales literature pertaining to the Fund may
quote a current distribution rate, yield, total return, average annual total
return and other measures of performance as described elsewhere in this
Statement of Additional Information with the substitution of net asset value for
the public offering price.
    
 
   
    Sales literature referring to the use of the Company or any of its Funds as
a potential investment for Individual Retirement Accounts ("IRAs"), and other
tax-advantaged retirement plans may quote a total return based upon compounding
of dividends on which it is presumed no federal income tax applies.
    
 
   
    MONEY MARKET FUND--YIELD
    
 
   
    The Money Market Fund will attempt, consistent with safety of principal, to
achieve the highest possible yield from its investments. The Money Market Fund's
yield is its current investment income expressed in annualized terms. Yield
quotations for the Money Market Fund will include an annualized historical
yield, carried at least to the nearest hundredth of one percent, based on a
specific seven-calendar-day period. Yield quotations are calculated by (1)
determining the net change (exclusive of capital changes) in the value of a
hypothetical pre-existing 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 get the base period return, then
    
 
                                       55
<PAGE>
   
(3) multiplying the base period return by the dividend obtained by dividing 365
by 7. The resulting yield figure is carried to the nearest hundredth of one
percent.
    
 
   
    The Money Market Fund's effective yield for a specified seven-calendar-day
period is computed by (1) determining the net change (exclusive of capital
changes) in the value of a hypothetical pre-existing account having a balance of
one share at the beginning of the period, (2) subtracting a hypothetical charge
reflecting deductions from shareholder accounts; (3) dividing the difference by
the value of the account at the beginning of the base period to get the base
period return, and then (4) compounding the base period return by adding 1,
raising the sum to a power equal to 365 divided by 7 and subtracting 1 from the
result according to the following formula: EFFECTIVE YIELD = [(BASE PERIOD
RETURN + 1)(356/7)]-1. The resulting yield figure is carried to the nearest
hundredth of one percent.
    
 
   
    The calculations include (1) the value of additional shares purchased with
dividends declared on the original share and dividends declared on both the
original share and any additional share, and (2) all fees (other than
nonrecurring fees or sales charges) charged to all shareholder accounts, in
proportion to the length of the base period and the Money Market Fund's average
account size. The calculations do not reflect any realized gains or losses from
the sale of securities or any unrealized appreciation or depreciation on
portfolio securities. The yield computation may be of limited use for
comparative purposes as charges at the account level will decrease the yield.
    
 
   
    Current and compounded yields fluctuate daily and will vary with factors
such as interest rates, the quality and length of maturities and the type
investments in the Money Market Fund's portfolio. Neither principal or interest
is insured or guaranteed.
    
 
   
    NON-MONEY MARKET FUNDS--YIELD
    
 
   
    Standardized yield for each Fund (other than the Money Market Fund) is
computed by dividing the Fund's interest income (in accordance with specific
standardized rules) for a given 30-day or one month period, net of expenses, by
the average number of shares entitled to receive distributions during the
period, dividing this figure by the Fund's net asset value per share at the end
of the period and annualizing the result (assuming compounding of income in
accordance with specific standardized rules) in order to arrive at an annual
percentage rate. The 30-day yield figure is calculated for each class of each
Fund according to a formula prescribed by the SEC. The formula can be expressed
as follows:
    
 
   
                            Yield = 2[(a-b + 1)(6)-1]
                                       ---
                                       cd
    
 
   
Where:
    
 
   
    a = dividends and interest earned during the period.
    
 
   
    b = expenses accrued for the period (net of reimbursement).
    
 
                                       56
<PAGE>
   
    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.
    
 
   
    For the purpose of determining the interest earned (variable a in the
formula) on debt obligations that were purchased by a Fund at a discount or
premium, the formula generally calls for amortization of the discount or
premium; the amortization schedule will be adjusted monthly to reflect changes
in the market values of the debt obligations.
    
 
   
    Investors should recognize that, in periods of declining interest rates, the
yield will tend to be somewhat higher than prevailing market rates, and in
periods of rising interest rates the yield will tend to be somewhat lower. In
addition, when interest rates are falling, moneys received by the Fund from the
continuous sale of its shares will likely be invested in portfolio instruments
producing lower yields than the balance of the Fund's portfolio, thereby
reducing the current yield of the Fund. In periods of rising interest rates, the
opposite result can be expected to occur.
    
 
   
    Yield information is useful in reviewing the performance of a Fund, but
because yields fluctuate, this information cannot necessarily be used to compare
an investment in shares of the Fund with bank deposits, savings accounts and
similar investment alternatives that often provide an agreed or guaranteed fixed
yield for a stated period of time. Shareholders of a Fund should remember that
yield is a function of the kind and quality of the instruments in the Fund's
portfolio, portfolio maturity, operating expenses and market conditions.
    
 
   
    TOTAL RETURN
    
 
   
    Standardized total returns quoted in advertising and sales literature
reflect all aspects of a Fund's return, including the effect of reinvesting
dividends and capital gain distributions, any change in the Fund's net asset
value per share over the period and maximum sales charge, if any, applicable to
purchases of the Fund's shares. A cumulative total return reflects a Fund's
performance over a stated period of time. An average annual total return
reflects the hypothetical annually compounded return that would have produced
the same cumulative total return if the Fund's performance had been constant
over the entire period. Because average annual returns tend to even out
variations in a Fund's return, investors should recognize that such returns are
not the same as actual year-by-year results. To illustrate the components of
overall performance, a Fund may separate its cumulative and average annual
returns into income results and capital gain or loss.
    
 
                                       57
<PAGE>
   
    The average annual total return figures for the Funds described in the
Prospectuses are computed for a class according to a formula prescribed by the
SEC. The formula can be expressed as follows:
    
 
   
                        P(1 + T)TO THE POWER OF n = ERV
    
 
   
Where P  =  a hypothetical initial payment of $1,000;
 
      T  =  average annual total return;
 
      n  =  number of years; and
 
      ERV = Ending Redeemable Value of a hypothetical $1,000
            investment made at the beginning of the 1-, 5- or
            10-year periods at the end of a 1-, 5- or 10-year
            period (or fractional portion thereof), assuming
            reinvestment of all dividends and distributions.
 
    
 
   
    The ERV assumes complete redemption of the hypothetical investment at the
end of the measuring period.
    
 
   
    The aggregate total return figures described in the Prospectuses represent
the cumulative change in the value of an investment in a class for the specified
period are computed by the following formula:
    
 
   
                        Aggregate Total Return = ERV - P
                                                 ---
                                                  P
    
 
   
Where P  =  a hypothetical initial payment of $1,000; and
 
      ERV = Ending Redeemable Value of a hypothetical $1,000
            investment made at the beginning of a 1-, 5- or
            10-year period at the end of the 1-, 5- or 10-year
            period (or fractional portion thereof), assuming
            reinvestment of all dividends and distributions.
 
    
 
   
    YIELD AND TOTAL RETURN FIGURES ARE BASED ON HISTORICAL EARNINGS AND ARE NOT
INTENDED TO INDICATE FUTURE PERFORMANCES.
    
 
   
    A Fund's performance is a function of its portfolio management in selecting
the type and quality of portfolio securities and is affected by operating
expenses of the Fund and market conditions. A shareholder's investment in a Fund
is not insured or guaranteed. These factors should be carefully considered by
the investor before making any investment in any Fund.
    
 
   
    MULTI-CLASS PERFORMANCE
    
 
   
    The Multi-Class Funds converted from a single-class to a multi-class
structure. That single class of shares was converted to Class T Shares,
effective December 31, 1998. Existing shareholders as of December 31, 1998
became shareholders in Class T.
    
 
   
    The performance calculations for the classes of the Multi-Class Funds, other
than the Class T Shares, and any classes that might be created after the Class T
Shares, may be stated so as to include the performance of the Fund's Class T
Shares. For these
    
 
                                       58
<PAGE>
   
purposes, the inception of the Class T Shares is the inception of the Fund.
Generally, performance of the Class T Shares will not be restated to reflect the
expenses or expense ratio of another class. For example, the inception of
performance for the Class A Shares will be deemed to be the inception date of
the Class T Shares and the performance of the Class T Shares (based on the Class
T Shares' actual expenses) from the inception of Class T Shares to the inception
of Class A Shares will be deemed to be the performance of the Class A Shares for
that period. For standardized total return calculations, the current maximum
initial sales load Class A Shares would be used in determining the total return
of Class A Shares as if assessed at the inception of Class T Shares.
    
 
   
                                  COMPARISONS
    
 
   
    To help investors better evaluate how an investment in a Fund might satisfy
their investment objective, advertisements and other materials regarding the
Company or any of its Funds may discuss various measures of the Fund's
performance as reported by various financial publications. Materials may also
compare performance (as calculated above) to performance as reported by other
investments, indices, and averages. The following publications, indices, and
averages may be used:

    In assessing such comparisons of performance, an investor should keep in
mind that the composition of the investments in the reported indices and
averages is not identical to the portfolio of any Fund, that the averages are
generally unmanaged, and that the items included in the calculations of such
averages may not be identical to the formula used by any Fund to calculate its
figures. In addition there can be no assurance that any series of the Company
will continue this performance as compared to such other averages.

ITEM 25.    INDEMNIFICATION.

      The Registrant has agreed to indemnify its directors to the maximum
extent permitted by applicable law against all costs and expenses (including,
but not limited to, counsel fees, amounts of judgments paid, and amounts paid in
settlement) reasonably incurred in connection with the defense of any actual or
threatened claim, action, suit or proceeding, whether civil, criminal,
administrative, or other, in which he or she may be involved by virtue of such
person being or having been such director.  Such indemnification is pursuant to
Section 3.15 of the Registrant's By-Laws, a copy of which is attached as Exhibit
2 to Post-Effective Amendment No. 7 to this Form N-1A Registration Statement.
    

      Insofar as indemnification for liability arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable.  In the event that a claim for indemnification against
such liabilities (other than the payment by the registrant of expenses incurred
or paid by a director, officer or


                                         C-2
<PAGE>

controlling person of the registrant in the successful defense of any action, 
suit or proceeding) is asserted by such director, officer or controlling 
person in connection with the securities being registered, the registrant 
will, unless in the opinion of its counsel the matter has been settled by 
controlling precedent, submit to a court of appropriate jurisdiction the 
question whether such indemnification by it is against public policy as 
expressed in the Act and will be governed by the final adjudication of such 
issue.

ITEM 28.    LOCATION OF ACCOUNTS AND RECORDS.

      All accounts, books, and other documents required to be maintained by
Section 31(a) of the Investment Company Act of 1940 and the Rules promulgated
thereunder will be maintained at the office of SM&R at 2450 South Shore

ITEM 29.    MANAGEMENT SERVICES.

      There are no management-related service contracts to which the Registrant
is a party not discussed under Part A or Part B of this Registration Statement.

ITEM 30.    UNDERTAKINGS.

      TEXAS OPTIONAL RETIREMENT PROGRAM.  The Government Income Fund and the
Primary Fund offer shares as investments for custodial accounts that meet the
requirements of Section 403(b)(7) of the Internal Revenue Code of 1986, as
amended (the "Code"), in connection with the Texas Optional Retirement Program
(the "Program").  Under the Program, a custodial account for each participating
employee ("Participant") is established in the name of SM&R.  The Program, as
interpreted by the Texas Attorney General, imposes certain restrictions on early
withdrawals from custodial accounts.  Section 22(e) prohibits a registered
investment company from suspending a shareholder's right of redemption or
postponing payment on redemption of any redeemable security for more than seven
days after tender of the security.
    


                                         C-7
<PAGE>

   
      The Staff of the Securities and Exchange Commission took a no-action
position under Section 22(e) of the 1940 Act permitting the Government Income
Fund and the Primary Fund to offer shares in connection with the Program as
contemplated above (See SM&R Capital Funds, pub. avail. Sept. 17, 1992 (the "No-
Action Letter")).  The Staff took its position based on the Registrant's
representation that the Funds and SM&R would comply with conditions set forth in
the No-Action Letter.  In this regard, each Fund and SM&R has complied with the
following provisions of the No-Action Letter:

      (a)   Appropriate disclosure regarding the restrictions on redemption
            imposed by the Program is included in this Registration Statement
            on Form N-1A and the applicable Prospectuses included in this
            Registration Statement.

      (b)   Appropriate disclosure regarding the restrictions on redemption
            imposed by the Program is included in any sales literature used in
            connection with the offer of the relevant Fund shares to
            Participants in connection with the Program.

      (c)   The Fund and SM&R instruct salespeople who solicit Participants to
            purchase Fund shares specifically to bring the restrictions on
            redemption imposed by the Program to the attention of the potential
            Participants.

      (d)   The Fund and SM&R obtain from each Participant who purchases Fund
            shares in connection with the Program, prior to or at the time of
            purchase, a signed statement acknowledging the restrictions on
            redemption imposed by the Program.

                    DISTRIBUTION AND SHAREHOLDER SERVICING PLAN

                                     May 29, 1998

     This Distribution and Shareholder Servicing Plan (the "Plan") is adopted by
SM&R Investments, Inc., a corporation organized under the laws of the State of
Maryland (the "Fund"), pursuant to Rule 12b-1 ("Rule 12b-1") under the
Investment Company Act of 1940, as amended (the "1940 Act") for two of the
Fund's series: the Government Income Fund Series and the Tax Free Fund Series
(individually and collectively, the "Series").

     Each Series currently has a single class of shares, but it is intended that
five new classes will be established so there will be six classes of shares of
common stock (the "Shares") of each Series, designated as the Class T Shares
(existing shareholders), the Class A Shares, the Class B Shares, the Class C
Shares, the Class J Shares (network), and the Class Y Shares (institutional
shareholders), respectively.  This Plan describes distribution services and
shareholder servicing to be provided by Securities Management and Research, Inc.
("SM&R") (investment adviser and principal underwriter to the Fund), any person
providing ongoing servicing to shareholders of the Series (each, a "Service
Provider"), or any distributor of the Series' Shares (each, a "Distributor") in
connection with the Class A, Class B, Class C and Class J Shares.  The Plan also
specifies the deductions from Series assets to pay for such services.

SECTION 1. AMOUNT OF PAYMENTS: DISTRIBUTION AND SHAREHOLDER SERVICE FEES

     (a) The two Series will pay distribution fees (the "Distribution Fees")
and/or shareholder service fees (the "Service Fees") with respect to each of the
Class A, Class B, Class C and Class J Shares of that Series (the "12b-1
Classes") for distribution-related services and shareholder services,
respectively, provided to each such Class of Shares.  The Distribution Fee and
Service Fee, as applicable, for each Class of Shares shall be computed as an
annual percentage of the value of the average daily net assets of the two Series
attributable to such Class, as follows:

     (b) The Distribution Fees to be paid under this Plan will be calculated
daily (as a percentage of average daily net assets) and paid periodically by
each of the two Series with respect to the Shares of the relevant 12b-1 Classes
of that Series at the annual rates indicated above. 

     (c) The Service Fees to be paid under this Plan will be calculated daily
(as a percentage of average daily net assets) and paid periodically by each of
the two Series with respect to the Shares of the relevant 12b-1 Classes of that
Series at the annual rates indicated above. 

     (d) Payments under this Plan are not tied exclusively to shareholder
services or distribution expenses actually incurred by SM&R or any Service
Provider or Distributor; the payments may exceed or be less than expenses
actually incurred by SM&R, a Service Provider and/or a Distributor.  

SECTION 2.  DISTRIBUTION AND SHAREHOLDER SERVICES PROVIDED.

     The Distribution Fees payable with respect to Class B, Class C and Class J
Shares of the two Series are intended to compensate SM&R, or enable SM&R to
compensate other persons, including Distributors, for services that are
primarily intended to result in, or that are primarily attributable to, the sale
of such respective Classes of Shares of the Series ("Selling Services").  The
Service Fees payable with respect to the Class A, Class B and Class C Shares of
the Series are intended to compensate SM&R, or enable SM&R to compensate Service
Providers, for providing ongoing servicing to shareholders of the Series
("Shareholder Services").  

     "Selling Services" when used in this Plan include, but are not limited to:
compensation of sales personnel, training and supervision of sales personnel,
advertising, marketing, and other promotional expenses (including the
preparation of, printing, and making of sales literature), and the printing and
distribution to prospective investors in the Series of prospectuses and
statements of additional information, that are used in connection with sales of
the relevant 12b-1 Classes of the Series and distributing such Classes of Shares
of the Series.  In providing compensation for Selling Services in accordance
with this Plan, SM&R is expressly authorized (i) to make, or cause to be made,
payments reflecting an allocation of overhead and other office expenses related
to the distribution of the relevant 12b-1 Classes of each Series; (ii) to make,
or cause to be made, payments, or to provide for the reimbursement of expenses
of, persons who provide support services in connection with the distribution of
the relevant 12b-1 Classes of each Series; and (iii) to make, or cause to be
made, payments to financial intermediaries who have sold the Shares of the
relevant 12b-1 Classes.  

     "Shareholder Services" as used in this Plan mean all forms of shareholder
liaison services, as SM&R deems appropriate for functions such as maintaining
shareholder accounts, providing shareholder liaison services, responding to
customer inquiries, and providing shareholders with information on their
investments and about the Series.

SECTION 3. APPROVAL OF PLAN AND RELATED AGREEMENTS.

     (a) SHAREHOLDER APPROVAL.  Neither this Plan nor any related agreements
will take effect with respect to a 12b-1 Class of a Series, and no fee will be
deducted or payable in accordance with Section 1 of this Plan, with respect to
the Shares of such 12b-1 Class of a Series, until this Plan has been approved by
a vote of at least a majority of the outstanding voting securities represented
by that Class, if adopted after any public offering of the Shares of that Class
or the sale of such Shares to persons who are not affiliated persons of the Fund
or affiliated persons of such persons.  This Plan will be deemed to have been
approved by shareholders of a 12b-1 Class of a Series so long as a majority of
the outstanding voting securities of the shareholders of such 12b-1 Class vote
for the approval of the Plan, notwithstanding that: (i) the Plan has not been
approved by a majority of the outstanding voting securities represented by any
other Class; (ii) the Plan has not been approved by a majority of the 
outstanding voting securities of the relevant Series of the Fund; or (iii) the
Plan has not been approved by a majority of the outstanding voting securities
of the Fund.

     (b) DIRECTOR APPROVAL.  Neither this Plan nor any related agreements will
take effect with respect to any Class of Shares of a Series until approved by:

     (i) a majority vote of the full Board of Directors of the Fund (the
     "Board"), and 

     (ii) a majority vote of those directors who are not interested persons of
     the Fund and who have no direct or indirect financial interest in the
     operation of this Plan or in any agreements related to it (the "Independent
     Directors"), 

     cast in person at a meeting called for the purpose of voting on this Plan
and the related agreements.  In voting to approve the implementation or
continuance of this Plan (see Section 4 below), the directors must conclude, in
exercise of reasonable business judgment and in light of their fiduciary duties,
that there is a reasonable likelihood that the Plan will benefit the relevant
Class of the Series and its shareholders.

SECTION 4. CONTINUANCE OF PLAN.

     This Plan will continue in effect with respect to a 12b-1 Class of Shares
of a Series from year to year so long as its continuance is specifically
approved annually by vote of the Board in the manner described in Section 3(b)
above.  The Board will evaluate the appropriateness of this Plan with respect to
the Shares of each of the respective 12b-1 Classes of each Series and its
payment terms on a continuing basis and in doing so will consider all relevant
factors, including the types and extent of Shareholder Services and/or Selling
Services provided by SM&R, Service Providers and/or Distributors and amounts
SM&R, Service Providers and/or Distributors receive under this Plan.

                                MULTIPLE CLASS PLAN
                                          
                                    May 29, 1998

     This Multiple Class Plan (the "Multi-Class Plan") is adopted by SM&R
Investments, Inc., a corporation organized under the laws of the State of
Maryland (the "Fund"), pursuant to Rule 18f-3 of the under the Investment
Company Act of 1940, as amended (the "1940 Act") for two of the Fund's series: 
the Government Income Fund Series and the Tax Free Fund Series (individually and
collectively, the "Series").(1)

     Each of the two Series currently has a single class of shares, but it is
intended that five new classes of those two Series will be established so there
will be six classes of shares of common stock (the "Shares"), designated as the
Class T Shares (existing shareholders), the Class A Shares, the Class B Shares,
the Class C Shares, the Class J Shares (network), and the Class Y Shares
(institutional shareholders), respectively. These classes of Shares have
different sales charges and distribution and service ("12b-1") fee structures.
 
SECTION 1: DISTRIBUTION ARRANGEMENTS AND SERVICE FEES

     (a)  INTRODUCTION. 

     Each Class of Shares of the two Series will have the same relative rights
and privileges, except that, as set forth in this Plan, they shall differ with
respect to (i) sales, distribution and shareholder services and other charges
and expenses as initially provided for in Section 1 of this Plan and as
subsequently provided for in the Fund's prospectus and statement of additional
information, as the same may be amended from time to time (each a "Prospectus"
and "SAI," and collectively, the "Prospectus" and "SAI"); (ii) the exclusive
right of each Class of Shares to vote on matters submitted to shareholders that
relate solely to that Class or for which the interests of one Class differ from
the interests of another Class or Classes; (iii) such differences relating to
eligible investors as may be set forth in the Prospectus and SAI; (iv) the
designation of each Class of Shares; and (v) conversion features.

     The board of directors of the Fund (the "Board") may determine in the
future that other distribution arrangements, allocations of expenses (whether
ordinary or extraordinary) or services 



- --------------------
     (1) The Primary Fund Series will only have one class (Class T, for existing
shareholders) and the proposed new Money Market Fund will only have one class,
with no sales load and no Rule 12b-1 Distribution or Shareholder Fees.

<PAGE>

to be provided to a Class of Shares are appropriate and amend this Plan
accordingly without the approval of shareholders of any Class to the extent
permitted by law. 

     (b) DISTRIBUTION AND SHAREHOLDER SERVICES FEES: As discussed below, the
Class A, Class B, Class C and Class J Shares (the "12b-1 Classes") shall be
offered by each of the two Series pursuant to a Distribution and Shareholder
Servicing Plan, adopted pursuant to Rule 12b-1 under the 1940 Act ("Rule 12b-1
Plan"), providing for a distribution fee (the "Distribution Fee") and a
shareholder services fee (the "Service Fee") at annual rates computed based on
the value of the average daily net assets of the that Series attributable to the
relevant Classes of Shares.  Such fees shall be calculated daily and paid
periodically by the Series.  The Distribution Fee is intended to compensate
Securities Management and Research, Inc. ("SM&R"), or enable SM&R to compensate
other persons, including any distributor of Shares, for services that are
primarily intended to result in, or that are primarily attributable to, the sale
of Shares attributable to the relevant 12b-1 Class.  The Service Fee payable
under the Plan is intended to compensate SM&R, or enable SM&R to compensate
other persons ("Service Providers"), for providing ongoing servicing and/or
maintenance of the accounts of shareholders of the applicable Class of each
Series ("Shareholder Services").

     (c)  ADMINISTRATIVE SERVICE FEE.  As discussed below, all six Classes of
Shares of the Fund shall be subject to an administrative service fee (the
"Administrative Fee") at an annual rate computed based on the value of the
average daily net assets of each Series.  The Administrative Fee declines with
respect to higher asset levels, as set forth in the Prospectus and/or SAI (as
revised from time to time) and an administrative services agreement between the
Fund and SM&R (the "Administrative Agreement").  Pursuant to the Administrative
Agreement, SM&R has agreed(2) to pay the Series or to reimburse the Series for
the expenses attributable to any Class (including the advisory fee and
Administrative Fee paid to SM&R and any other fees allocated to all Classes of
shares of the Series based on average daily net assets, but exclusive of
interest, taxes, the Service Fee, the Distribution Fee, commissions and other
expenses incidental to portfolio transactions and any other Class Expenses, as
defined below) in excess of 1.25% per year of such Class' average daily net
assets.  

     (d)  CONTINGENT DEFERRED SALES CHARGE.  As discussed below, some Class A
Shares and all Class B and Class C Shares shall be subject to a contingent
deferred sales charge ("CDSC") calculated as a specified percentage of the
offering price of the Shares of the relevant Class at the time of purchase.  No
CDSC shall be imposed on Shares of a Class unless so provided in the Prospectus.
No CDSC shall be imposed on increases in the net asset value of the Shares being



- --------------------
     (2)  As of the date hereof, the Administrative Agreement does not provide
for multiple classes and provides for the 1.25% expense limit on a Series by
Series basis (I.E., to apply separately for each Series), and does not provide
for the Service or Distribution Fee.  It is anticipated that the Administrative
Agreement will be revised to provide for multiple classes, in accordance with
this Multi-Class Plan, before this Plan is implemented.


                                         -2-

redeemed above the initial purchase price.  No CDSC shall be assessed on Shares
derived from reinvestment of dividends or capital gain distributions.  SM&R, in
its discretion, may waive a CDSC otherwise due upon the redemption of Shares on
terms disclosed in the Prospectus or SAI and as allowed under Rule 6c-10 and
other applicable rules of the 1940 Act.

     (e)  EXCHANGE PRIVILEGES.  Exchanges shall be permitted, without charge,
between each Class of Shares of a Series and corresponding classes of other
investment funds advised by SM&R, including the classes of the other series, and
the classes of American National Growth Fund, Inc., American National Income
Fund, Inc. and Triflex Fund, Inc., (each, a "Portfolio"), on terms described in
the Prospectus.  Each Class of Shares also will be exchangeable for shares of
the American National Money Market Fund Series (the ("Money Market Series"), the
proposed fourth series of the Fund, which will become available for sale to the
public in the fourth quarter of 1998 and offer a single class of Shares.(3)
 
     (f)  CLASS-SPECIFIC ARRANGEMENTS.  

     The Classes of Shares have the following service and distribution fee
     arrangements:

     charge as approved from time to time by the Board and set forth in the

     with respect to investments in Class A Shares in an amount of One Million
     Dollars ($1,000,000.00) or more.  The currently proposed front-end sales
     charges and corresponding breakpoints for the Class A Shares are set forth
     in Appendix A - Multi-Class Structure.  Shares that are not subject to a
     front-end sales charge because a purchaser invests $1,000,000.00 or more in
     Class A Shares shall be subject to a CDSC of 1% for a period of 13 months. 
     Class A Shares also shall be  (i) subject to a Service Fee of .25% of the

     relative net asset value per Share of each Class without the imposition of
     any sales charge, fee or other charge.  Class B Shares may be exchanged for

SECTION 2:  ALLOCATION OF CLASS EXPENSES

     Each Class of Shares of each Series represents interests in that Series,
and each has the same rights, preferences, voting powers, restrictions and
limitations, as the other Classes, except as follows:

     (1)  expenses related to the distribution of a Class of Shares or to the
          services provided to shareholders of a Class of Shares shall be borne
          solely by such Class; 

     (2)  each Class will bear different Class Expenses (as defined below); 

     (3)  each Class will have exclusive voting rights with respect to matters
          that exclusively affect such Class; and

     (4)  each Class will bear a different name or designation.  

     Expenses that are directly attributable to a particular Class of Shares
will be incurred by that Class of Shares.  The Board, acting in its sole
discretion, has determined that the following expenses attributable to the
Shares of a particular Class ("Class Expenses") will be borne solely by the
Class to which they are attributable:

     (1)  asset-based distribution fees and shareholder service fees;
     (2)  transfer agency fees attributable to a particular Class; 


                                         -5-

<PAGE>



     (3)  expenses related to preparing, printing, mailing and distributing
          materials such as shareholder reports, prospectuses and proxy
          statements to current shareholders of a specific Class; 
     (4)  state and federal registration fees incurred by a specific Class; 
     (5)  litigation and other legal expenses relating to a particular Class; 
     (6)  directors' fees and expenses incurred as a result of issues relating
          solely to a particular Class; 
     (7)  accounting, audit and tax expenses relating to a specific Class; 
     (8)  the expenses of administrative personnel and services required to
          support the shareholders of a specific Class; and 
     (9)  fees and other payments made to entities performing services for a
          particular Class, including account maintenance, dividend disbursing
          or subaccounting services.

     Class Expenses may be waived or reimbursed proportionately and on a pro
rata basis between Classes of a Series by SM&R, the Series' investment adviser
and distributor.  Investment advisory fees, custodial fees, and other expenses
relating to the management of the Series' assets shall not be allocated on a
class-specific basis.  

SECTION 3:  ALLOCATION OF SERIES INCOME AND EXPENSES

     Income, realized and unrealized capital gains and losses, and expenses that
are not allocated to a specific Class pursuant to Section 2 above, shall be
allocated to each Class of a Series on the basis of the proportionate net assets
of that Class in relation to the net assets of that Series.  (Likewise, income,
realized and unrealized capital gains and losses, and expenses that are not
allocated to a specific Series shall be allocated to each Series of the Fund on
the basis of the proportionate net assets of that Series in relation to the net
assets of the Fund.)  On a daily basis, the total income, dividends, other
income accrued and Series-level expenses incurred are multiplied by the
proportionate value of the Series' net assets attributable to each Class to
determine the income and expenses attributable to that Class for the day. 
Expenses properly attributable to each Class are recorded separately and charged
to that Class.  Net income for each Class is then determined for the day and
segregated on the Fund's general ledger.  Dividends are calculated in the same
manner for each Class and declared and paid on all Classes of Shares on the same
days and at the same times.

SECTION 4:  AMENDMENTS

     This Multi-Class Plan may not be amended to change any material provision
unless such amendment is approved by a vote of the majority of the Board,
including a majority of the Directors who are not interested persons of the Fund
(as defined in Section 2(a)(19) of the 1940 Act) (the "Independent Directors"),
based on its finding that the amendment is in the best interest of each Class
individually and the relevant Series as a whole.

interests of each Class of Shares and each Series as a whole.
