                      INVESTMENT STRATEGIES FOR A CHANGING WORLD
<PAGE>

THE 3 "GOLDEN RULES"
OF MUTUAL FUND INVESTING


1    SET AN INVESTMENT GOAL THAT INCLUDES "HOW MUCH" AND "BY WHEN."
          You must have an investment goal before you can reasonably evaluate
     which mutual funds best suit your needs.  Are you saving for a child's
     education, a down payment on a house, or for retirement?  Are your
     retirement savings meant to enhance your pension and allow you to travel?
     Or, will you depend on income from your investments for living expenses?

          Every financial goal has a different dollar amount and a 
     different timetable. How you invest and where you invest can only be 
     decided once you know why you're investing. 

2    KNOW YOUR PERSONAL TOLERANCE FOR RISK AND DIVERSIFY YOUR INVESTMENTS.
          Every investment option has risk attached to it.  Knowing how much
     risk you can tolerate, both financially and emotionally, is as important as
     knowing your financial goal.  The method for minimizing risk that is most
     often recommended by financial advisors is diversification.

          Rather than have all of your investment in one kind of fund, you
     should consider owning different types of mutual funds.  Funds that invest
     in different types of assets.  Remember, no single mutual fund is going to
     perform well in every economic climate.  By diversifying your portfolio,
     you spread out the risk and the rewards of investing.

     (ON THE INSIDE OF THE BACK COVER, THERE IS A RISK-TOLERANCE QUIZ THAT MAY
     GIVE YOU SOME INSIGHT INTO HOW YOU CAN APPROACH YOUR INVESTMENT STRATEGY.)


3    JUST DO IT!
          Whether you're trying to get into physical shape or fiscal shape, you
     know that the sooner you get started, the sooner you'll see results.

          Building wealth is easier when you start early and take advantage of
     compounding.  Everyone understands how interest on a credit card or
     mortgage can add up if it's left alone.  That's the power of compounding. 
     The same is true for saving and investing money.  Start now and let
     compounding put your money to work.

                       SECURITIES MANAGEMENT AND RESEARCH, INC.
                                       ("SM&R")

For over 30 years, the financial professionals at Securities Management and
Research, Inc. who manage the SM&R Mutual Funds, have become a family investment
tradition based on our commitment, experience and ability to thrive in changing
economic environments. We hope you will consider our family of funds as you
design your investment portfolio.

EACH FUND IS DESIGNED TO PURSUE A DISTINCT FINANCIAL OBJECTIVE.
     You can concentrate your assets in one fund, move them back and forth
     between funds (exchange*) or spread them over a combination of funds. You
     have the opportunity to achieve the exact combination of investments that
     is compatible with your investment goals.

A DISCIPLINED, BOTTOM-UP APPROACH TO STOCK INVESTMENT.
     Before a company's stock is purchased for an SM&R fund, it must meet
     strict performance criteria. Each company is evaluated on the basis of its
     past performance, future growth strategies, and price relative to all other
     companies on its industry and economic sector.  You can rest assured that 
     a rigorous, objective performance model drives every decision.


OUR UNIQUE TEAM APPROACH TO FUND MANAGEMENT OFFERS YOU MAXIMUM BENEFITS.
     Normally, the performance of a mutual fund is solely dependent on the
     expertise and decisions of one individual fund manager. At SM&R, our
     portfolio managers work in a team environment to determine the strategy for
     each portfolio and to approve the list of securities for use in the
     portfolios. The team approach provides further assurance that each
     portfolio will receive the maximum benefits of the organization's talents
     and resources.


     PLEASE TAKE A MOMENT TO REVIEW THE INFORMATION AND PROSPECTUSES FOR EACH OF
     OUR FUNDS. THEN LET US HELP YOU DESIGN AN INVESTMENT PORTFOLIO THAT CAN
     HELP YOU MEET YOUR GOALS.

     * For income tax purposes, an exchange is treated as a sale of 
       shares and will generally result in a capital gain or loss. The 
       redemption of B or C shares may be subject to a CDSC depending upon 
       when you initially purchased the shares.

     Keep in mind that like all securities products, investment return and 
     principal values will fluctuate, and when redeemed, shares may be worth 
     more or less than their original cost.  As with any securities product, 
     you should obtain and carefully read the prospectus, which includes all 
     fees and expenses, before investing.

RISK/RETURN SUMMARY                                       SM&R GROWTH FUND, INC.
- --------------------------------------------------------------------------------
 
GROWTH FUND'S INVESTMENT OBJECTIVE
                 The Growth Fund seeks long-term capital growth by investing
                 primarily in common stocks that provide an opportunity for
                 capital appreciation over time.
 
GROWTH FUND'S PRINCIPAL INVESTMENT STRATEGIES
                 The Growth Fund normally invests at least 85% of its total
                 assets in common stocks. In selecting stocks, this fund:
                 - chooses the stocks of financially sound companies that have a
                   proven ability to make and sustain a profit over time, and
                 - places an emphasis on companies with growth potential.
 
                 The Growth Fund generally purchases a higher proportion of
                 stocks (relative to their market weight) from those sectors of
                 the market with higher growth prospects, referred to as
                 "overweighting." Examples of sectors with higher growth
                 prospects currently include technology, healthcare, and
                 consumer staples. On the other hand, the fund generally
                 purchases a smaller proportion of stocks (relative to their
                 market weight) from sectors of the market with below average
                 growth characteristics (for example, utilities, basic
                 materials, and communications services), referred to as
                 "underweighting."
 
                 The Growth Fund may also invest in debt obligations (such as
                 convertible preferred stocks, debentures, and notes), including
                 below investment grade bonds ("junk" bonds).
 
PRINCIPAL RISKS OF INVESTING IN THE GROWTH FUND
                 You could lose money on your investment in the Growth Fund, or
                 it could underperform other investments, if any of the
                 following occurs:
                 - the stock market goes down
                 - the investment decisions of management (such as sector
                   overweighting and underweighting and individual stock
                   selection) do not achieve the desired results
                 - interest rates increase
                 - issuers of debt obligations default or are unable to pay
                   amounts due
 
                 Investments by the Growth Fund in smaller companies may involve
                 greater risks than larger established companies.
 
WHO MAY WANT TO INVEST IN THE GROWTH FUND
                 This fund may be appropriate if you:
                 - have long time horizons (ten years or more)
                 - are willing to accept higher short-term risk along with
                   higher potential long-term returns
                 - want to diversify your portfolio
                 - are investing for retirement or other goals that are many
                   years in the future
 
                 This fund may NOT be appropriate:
                 - if you are investing with a shorter time horizon
                 - if you are uncomfortable with an investment that will go up
                   and down in value
                 - as your complete portfolio

RISK/RETURN SUMMARY                                SM&R EQUITY INCOME FUND, INC.
- --------------------------------------------------------------------------------
 
EQUITY INCOME FUND'S INVESTMENT OBJECTIVE
                 The Equity Income Fund seeks current income with a secondary
                 objective of long-term capital appreciation.
 
EQUITY INCOME FUND'S PRINCIPAL INVESTMENT STRATEGIES
                 The Equity Income Fund normally invests at least 75% of its
                 assets in equity securities. This fund also invests in
                 preferred stocks and investment grade debt securities (such as
                 publicly traded corporate bonds, debentures, notes, commercial
                 paper, repurchase agreements, and certificates of deposit). In
                 selecting common and preferred stocks, the fund focuses on
                 companies with consistent and increasing dividend payment
                 histories and future earnings potential sufficient to continue
                 such dividend payments. This fund's goal is to maintain a
                 portfolio dividend yield (before fees and expenses) at least
                 50% greater than that of the S&P 500 Index.
 
                 The Equity Income Fund generally purchases a higher proportion
                 of stocks (relative to their market weight) from those sectors
                 of the market with greater dividend prospects, referred to as
                 "overweighting." Examples of sectors with greater dividend
                 prospects currently include financial companies like banks,
                 insurance companies, and real estate investment trusts. On the
                 other hand, the fund generally purchases a smaller proportion
                 of stocks (relative to their market weight) from sectors of the
                 market with below average dividend yields (such as technology
                 and consumer staples), referred to as "underweighting."
 
PRINCIPAL RISKS OF INVESTING IN THE EQUITY INCOME FUND
                 You could lose money on your investment in the Equity Income
                 Fund, or it could underperform other investments, if any of the
                 following occurs:
                 - the stock market goes down and/or interest rates increase
                 - the investment decisions of management (such as sector
                   overweighting and underweighting and individual stock
                   selection) do not achieve the desired results
                 - issuers of debt obligations default or are unable to pay
                   amounts due
                 - the fund cannot find a buyer for securities
 
                 Investments by the Equity Income Fund in smaller companies may
                 involve greater risks than larger established companies.
 
WHO MAY WANT TO INVEST IN THE EQUITY INCOME FUND
                 This fund may be appropriate if you:
                 - are looking for a fund that has both growth and income
                   components
                 - are seeking to protect the purchasing power of your money
                   while retaining the potential for growth and reducing
                   exposure to the volatility of the market
                 - are willing to accept higher short-term risk along with
                   higher potential long-term returns
                 - are retired or nearing retirement
 
                 This fund may NOT be appropriate if you:
                 - are investing for maximum return over a long time horizon
                 - require a high degree of stability of your principal
                 - desire your return to be either ordinary income or capital
                   gains, but not both

RISK/RETURN SUMMARY                                     SM&R BALANCED FUND, INC.
- --------------------------------------------------------------------------------
 
BALANCED FUND'S INVESTMENT OBJECTIVE
                 The Balanced Fund seeks to conserve principal, produce current
                 income, and achieve long-term capital appreciation.
 
BALANCED FUND'S PRINCIPAL INVESTMENT STRATEGIES
                 The Balanced Fund uses a "balanced" approach by investing part
                 of the assets in common stocks and the remainder in a
                 combination of high-grade bonds, convertible bonds, and money
                 market instruments. The ratio of stocks to bonds changes in
                 response to changing economic conditions. This flexibility may
                 help to reduce price volatility.
 
                 This fund's goal is relative stability of principal through a
                 balance of stocks, bonds, and cash. The stocks are diversified
                 and are selected based upon two models. One model is based on
                 profitability measurements and the other model is based on the
                 corporation's return on invested cash. The bonds, meanwhile,
                 may serve as a stabilizing force during times of eroding stock
                 market value, as well as provide a fixed income payment stream.
                 The fund invests at least 25% of assets in fixed income
                 securities, all of which are rated BBB or better (investment
                 grade). Common stocks purchased by the fund will have a market
                 capitalization of at least $100 million and be listed on a
                 national exchange.
 
PRINCIPAL RISKS OF INVESTING IN THE BALANCED FUND
                 You could lose money on your investment in the Balanced Fund,
                 or it could underperform other investments, if any of the
                 following occurs:
                 - interest rates increase or the stock market goes down
                 - issuers of debt obligations default or are unable to pay
                   amounts due
                 - the investment decisions of management do not achieve the
                   desired results
 
                 Investments by the Balanced Fund in smaller companies may
                 involve greater risks than larger established companies.
 
WHO MAY WANT TO INVEST IN THE BALANCED FUND
                 This fund may be appropriate if you:
                 - are seeking supplemental income and conservation of the
                   purchasing power of your capital
                 - are looking for a more conservative alternative to a
                   growth-oriented fund
                 - want a well-diversified and relatively stable investment
                   allocation
                 - need a core investment
                 - are retired or nearing retirement
 
                 This fund may NOT be appropriate if you:
                 - are investing for maximum return over a long time horizon
                 - desire your return to be either ordinary income or capital
                   gains, but not both
                 - require a high degree of stability of your principal

RISK/RETURN SUMMARY
- --------------------------------------------------------------------------------
 
TYPES OF INVESTMENT RISK
 
As indicated above, each of the three funds is subject to the following types of
risks to varying degrees:
 
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. THIS RISK APPLIES TO
ALL OF THE FUNDS, BUT MAY HAVE A GREATER IMPACT ON THE BALANCED AND EQUITY
INCOME FUNDS.
 
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. THIS RISK APPLIES TO ALL OF THE FUNDS, BUT MAY HAVE A GREATER IMPACT ON
THE BALANCED AND EQUITY INCOME FUNDS.
 
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.
 
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 over a ten year period, and
- - by showing how each fund's average annual returns for 1, 5, and 10 years
  compare to those of both a broad-based securities market index, and an index
  of funds with similar investment objectives.
 
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. We created the multiple classes
of shares on January 1, 1999. If multiple classes of shares of the 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
- --------------------------------------------------------------------
 
  - 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
 
  - 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 5.00% contingent deferred sales charge on Class B shares applies
    to redemptions during the first year after purchase. The charge declines to
    4.00% during the second year, 3.00% during the third year, 2.00% during the
    fourth year, 1.00% during the fifth year, and zero during the sixth 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) The "Management Fee" and "Other Expenses" shown for the funds are for the
    year ended December 31, 1997.
 
(7) "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 Growth, Equity Income, and Balanced Fund for the
    fiscal year ended December 31, 1997.
 
(8) 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% 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. During the
   fiscal year ended December 31, 1997, SM&R waived management fees of 0.10% for
   the Balanced Fund.

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:

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>
<CAPTION>
                                                                                SALES CHARGE AS A %
                                                         SALES CHARGE AS A %       OF NET AMOUNT

</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 five years of buying them.
The CDSC shown in the following table is a percentage of the offering price:
 
<TABLE>

                                                          CONTINGENT DEFERRED SALES
                                                                   CHARGE
                YEARS SINCE PURCHASE                     (AS A % OF OFFERING PRICE)
- -----------------------------------------------------  -------------------------------

                       Year 2                                         4.00%
                       Year 3                                         3.00%
                       Year 4                                         2.00%
                       Year 5                                         1.00%
                       Year 6+                                      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 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 Securities Management and Research, Inc. ("SM&R") on which you paid a
front-end sales charge. 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;
 
       (4) 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
 
       (5) Employees (or employers on behalf of employees) under any employee
           benefit plan not qualified under Section 401 of the Internal Revenue
           Code.
 
       Purchases in connection with employee benefit plans not qualified under
       Section 401 of the Internal Revenue Code will qualify for the above
       quantity discounts only if the fund 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
       fund's prospectus available to individual investors or employees,
       forwarding investments by such employees to the funds, and the like.
 
DISCOUNTS THROUGH A RIGHT OF ACCUMULATION. If you already own Class A or Class T
shares of a fund managed by SM&R, on which you paid a front-end sales charge,
you may be able to receive a discount when you buy additional shares. The
current net asset value of the shares you already own may be
"accumulated"--I.E., combined together with the dollar amount being invested--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 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.

           Directors (or by the distributor based on guidelines established by

           any sales expense to the Funds.
 
       YOU HAVE THE SOLE RESPONSIBILITY OF NOTIFYING SM&R THAT YOU INTEND TO
       QUALIFY UNDER ONE OF THESE CATEGORIES.
 
       The funds may terminate or change the terms of any waiver of sales
       charges at any time.
 
THE EDUCATION FUNDING INVESTMENT ACCOUNT PROGRAM. The Education Funding
Investment Account Program is a service expressly created to help investors
accumulate funds for their children's or grandchildren's college education by
reducing the standard sales charge breakpoints. Breakpoints for the Program
differ from standard breakpoints in two respects: (1) investments in Class A
shares of less than $100,000 are subject to a lower initial sales charge, and
(2) investments in Class A shares above $500,000 are not subject to an initial
sales charge. The following breakpoints
 
                                       14

apply to purchases of Class A shares made by individuals investing in the funds
through the use of The Education Funding Investment Account Program, as well as
the Education IRA:

</TABLE>
 
INVESTMENTS OF $500,000 OR MORE. If you invest $500,000 or more in Class A
shares, you do not pay any "front-end" sales charge. However, you will pay a
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 above.
 
TO PARTICIPATE IN THIS SPECIAL PLAN, INVESTORS MUST COMPLETE THE SPECIAL
EDUCATION FUNDING INVESTMENT ACCOUNT APPLICATION DESIGNED SPECIFICALLY FOR THE
PROGRAM OR AN EDUCATION IRA APPLICATION.
 
CLASS B WAIVERS OF CONTINGENT DEFERRED SALES CHARGES
 
The CDSC will be waived on the following redemptions of Class B shares:
 
       (1) 12% FREE AMOUNT. We waive the CDSC on redemptions pursuant to a
           systematic withdrawal plan of up to 12% of account value per year. We
           apply this 12% waiver on a per fund basis to the account value
           determined at the time you elect a systematic withdrawal plan.
           (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 12% 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) the disablity began after the shares were purchased;
           (b) 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;
           (c) the redemptions are made within one year following death or
               initial determination of disability; and
           (d) 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 four
           types of qualified retirement plans: IRAs, custodial accounts
           maintained pursuant to Code Section 403(b), deferred compensation
           plans qualifed under Code 457 and plans qualified under
 
                                       15
<PAGE>
           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 to the extent it does
               not exceed 12% annually of the participant's or beneficiary's
               account value;
           (b) tax-free rollovers or transfers of assets to another IRA, Section
               403(b) plan, Section 457 plan or Section 401 plan invested in
               Class B shares of one or more funds managed by SM&R;
           (c) tax-free returns of excess contributions or returns of excess
               deferral amounts; and
           (d) distributions upon the death or disability (as defined in the
               Code) of the participant or beneficiary.
 
       (4) SMALL ACCOUNTS. We waive the CDSC on redemptions by the funds of
           small accounts (accounts with a value less than $500).
 
       (5) SM&R INVESTMENTS. We waive the CDSC on redemptions of shares owned by
           SM&R or any of its affiliates.
 
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:

Class C Shares (LEVEL LOAD)...................................       0.75%       0.25%       1.00%
</TABLE>
 
       The distribution fee is for services that are primarily intended to
       result in or are primarily attributable to the distribution of the Class
       A, B, and C shares. The service fee is for providing ongoing servicing to
       shareholders of the Class B and C shares. These fees compensate SM&R, or
       enable 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. More investment information is in the Statement of Additional
Information. 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.
 
SM&R GROWTH FUND, INC.
(FORMERLY NAMED AMERICAN NATIONAL GROWTH FUND, INC.)
 
       The Growth Fund considers its portfolio investments and the composition
       of its total portfolio from the viewpoint of potential capital
       appreciation. The Growth Fund adjusts this composition from time to time
       in light of current conditions. Under normal conditions, the Growth Fund
       invests at least 85% of its total assets in common stocks.
 
       The Growth Fund invests in the stocks of financially sound companies that
       have a proven ability to make and sustain a profit over time. Management
       places an emphasis on companies with growth potential. The Growth Fund
       does not employ exotic investment strategies, such as using options and
       futures.
 
       We identify candidate stock investments based on (1) low equity valuation
       (price) and (2) improving earnings. Then, we evaluate each candidate
       stock on a fundamental basis by examining past financial performance,
       managerial skill and foresight, and relative valuation to industry peers
       and the market as a whole. We utilize this combination of disciplines and
       human judgement to drive our stock selection process. We believe in
       evaluating each company's prospects as opposed to relying on broad
       forecasts of industry prospects. We do not attempt to time economic,
       market, style or capitalization cycles. Diversification, or weighting of
       individual economic sectors, is also dictated by a combination of
       disciplines and human judgement to varying degrees. We believe in never
       having less than half or more than double the market weighting in any one
       sector. The Growth Fund limits cash to 15% of its assets unless
       circumstances dictate otherwise.
 
       Because of the Growth Fund's goal of seeking long-term capital growth,
       certain sectors of the market will have greater weight in the Growth
       Fund's portfolio while other sectors of the market will have lower
       representation. For example, the Growth Fund generally overweights the
       technology sector, which represents approximately 15% of the Standard &
       Poor's 500 Index, in the portfolio relative to its market weight. This
       overweighting reflects the higher growth prospects of technology
       companies relative to the average company in the market. At varying
       times, we may also overweight other sectors of the market providing above
       average growth prospects, like healthcare and consumer staples.
 
                                       17
<PAGE>
    Conversely, the Growth Fund generally underrepresents certain sectors of the
    market in its portfolio that tend to have below average growth
    characteristics, like utilities, basic materials, and communications
    services. As a result of such strategic overweighting and underweighting,
    the Growth Fund's performance may differ substantially from broad market
    indexes like the S&P 500 and tend to incur more price volatility than these
    indexes.
 
    The Growth Fund may invest in convertible preferred stocks rated at least
    "B" by Standard and Poor's Corporation ("S&P") or at least "b" by Moody's
    Investors Service, Inc. ("Moody's") preferred stock ratings, and convertible
    debentures and notes rated at least "B" by S&P and Moody's corporate bond
    ratings. Investments in convertible securities having these ratings may
    involve greater risks than convertible securities having higher ratings.
 
    The proportion of assets invested in any particular type of security can be
    expected to vary, depending on SM&R's appraisal of market and economic
    conditions. Common stocks and convertible securities purchased will be of
    companies that SM&R believes will provide an opportunity for capital
    appreciation. On a temporary basis, the Growth Fund may invest 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, in certificates of deposit in domestic banks and savings
    institutions having at least $1 billion of total assets, and in repurchase
    agreements.
 
SM&R EQUITY INCOME FUND, INC.
(FORMERLY NAMED AMERICAN NATIONAL INCOME FUND, INC.)
 
    The Equity Income Fund considers its portfolio investments and the
    composition of its total portfolio not only from the viewpoint of present
    and potential yield, but also from the viewpoint of potential capital
    appreciation. We adjust this composition of portfolio investments from time
    to time to best accomplish the Equity Income Fund's investment objectives
    under current conditions.
 
    In pursuit of its objectives, the Equity Income Fund will invest in common
    stocks, preferred stocks, and marketable debt securities selected in
    accordance with its investment objectives. Common and preferred stocks
    purchased will generally be of companies with consistent and increasing
    dividend payment histories that SM&R believes will have further earnings
    potential sufficient to continue such dividend payments. Debt securities
    include publicly traded corporate bonds, debentures, notes, commercial
    paper, repurchase agreements, and certificates of deposit in domestic banks
    and savings institutions having at least $1 billion of total assets. The
    proportion of assets invested in any particular type of security can be
    expected to vary, depending on SM&R's appraisal of market and economic
    conditions. Under normal conditions, the Equity Income Fund will invest at
    least 75% of its assets in equity securities rather than debt securities.
 
    We view common stocks, as well as investments in preferred stocks and bonds
    convertible into common stock, from their potential for capital appreciation
    in addition to their current and potential income yield. Our goal is to
    maintain a portfolio dividend yield (before fees and expenses) at least 50%
    greater than that of the S&P 500 Index.
 
    We identify candidate stock investments based on (1) low equity valuation
    (price) and (2) improving earnings. Then, we evaluate each candidate stock
    on a fundamental basis by
 
                                       18
<PAGE>
    examining past financial performance, managerial skill and foresight, and
    relative valuation to industry peers and the market as a whole. We utilize
    this combination of disciplines and human judgement to drive our stock
    selection process. We believe in evaluating each company's prospects as
    opposed to relying on broad forecasts of industry prospects. We do not
    attempt to time economic, market, style or capitalization cycles.
    Diversification, or weighting of individual sectors, is also dictated by a
    combination of disciplines and human judgement to varying degrees. We
    believe in never having less than half or more than double the market
    weighting in any one sector. Cash is limited to 15% of the fund unless
    circumstances dictate otherwise.
 
    Certain sectors of the market will have greater weight in the Equity Income
    Fund's portfolio while other sectors of the market will have lower
    representation. For example, the Equity Income Fund generally overweights
    the finance sector in its portfolio relative to that sector's market weight
    (which is approximately 16% of the Standard & Poor's 500 Index). This
    reflects the greater dividend prospects of financial companies like banks,
    insurance companies, and real estate investment trusts as compared to the
    average company in the market. At varying times, we may also overweight
    other sectors of the market that provide above average dividend prospects,
    like utilities and energy.
 
    Conversely, the Equity Income Fund generally underrepresents certain sectors
    of the market tending to have below average dividend yields, like
    technology, consumer staples, and healthcare. As a result of such strategic
    overweighting and underweighting, the Equity Income Fund's performance may
    differ substantially from broad market indexes like the S&P 500.
 
    Corporate debt obligations purchased by the Equity Income Fund will consist
    only of obligations rated either Baa or better by Moody's or BBB or better
    by S&P. Bonds which are rated Baa by Moody's are considered as medium grade
    obligations, that is, they are neither highly protected nor poorly secured.
    Bonds rated BBB by S&P are regarded as having an adequate capacity to pay
    interest and repay principal. Commercial paper and notes will consist only
    of direct obligations of corporations whose bonds and/or debentures are
    rated as set forth above.
 
SM&R BALANCED FUND, INC.
(FORMERLY NAMED TRIFLEX FUND, INC.)
 
    The Balanced Fund uses a "balanced" approach by investing part of its assets
    in stocks of well-known companies and the remainder in a combination of
    high-grade bonds, bonds convertible into the common stock of the issuing
    corporations, and money market instruments. We change the ratio of stocks to
    bonds in response to changing economic conditions. This flexibility helps to
    reduce price volatility.
 
    The Balanced Fund's goal is relative stability of principal through a
    balance of stocks, bonds, and cash. The stocks serve to capture the benefits
    that ownership in corporate America brings. The bonds, meanwhile, can serve
    as a stabilizing force during times of eroding stock market value, as well
    as provide a fixed income payment stream into the portfolio.
 
    The Balanced Fund will only purchase common stocks and convertible
    securities of corporations having a market capitalization of at least $100
    million, an operating history of at least three (3) years, and a listing on
    the New York Stock Exchange, American Stock Exchange, or Over-The-Counter
    markets. The Balanced Fund will only purchase corporate bonds rated
 
                                       19
<PAGE>
    either Baa or better by Moody's or BBB or better by S&P. Bonds which are
    rated Baa by Moody's are considered as medium grade obligations, that is,
    they are neither highly protected nor poorly secured. Bonds rated BBB by S&P
    are regarded as having an adequate capacity to pay interest and repay
    principal. Commercial paper and notes will consist only of direct
    obligations of corporations whose bonds and/or debentures are rated as set
    forth above. The Balanced Fund may also invest in repurchase agreements.
    This balanced investment policy is intended to reduce risk and to obtain
    results in keeping with the Balanced Fund's objectives.
 
    The Balanced Fund will invest in fixed-income securities and equity
    securities as described above. However, the Balanced Fund will sometimes be
    more heavily invested in equity securities and at other times it will be
    more heavily invested in fixed-income securities, depending on management's
    appraisal of market and economic conditions. SM&R believes that a fund that
    is wholly invested in fixed-income securities carries a large interest rate
    risk. Interest rate risk is the uncertainty about losses due to changes in
    the rate of interest on debt instruments. The major interest rate risk for
    investors, however, is not in the interest rate itself, but in the change in
    the market price of bonds that results from changes in the prevailing
    interest rate. Higher interest rates would mean lower bond prices and lower
    net asset value for the Balanced Fund's shareholders assuming no change in
    its current investment objective and portfolio. Diversifying the Balanced
    Fund's portfolio with investments such as commercial paper, convertible
    securities, and common stocks may reduce the decline in value attributable
    to the increase in interest rate and resulting decrease in the market value
    of bonds and may reduce the interest rate risk. However, stock prices also
    fluctuate in response to a number of factors, including changes in general
    level of interest rates, economic and political developments, and other
    factors which impact individual companies or specific types of companies.
    Such market risks cannot be avoided but can be limited through a program of
    diversification and a careful and consistent evaluation of trends in the
    capital market and fundamental analysis of individual equity holdings.
 
    The Balanced Fund's goal of preservation of capital while owning common
    stocks depends on various factors, including the sustained long-term growth
    of the United States economy. SM&R recognizes that recessions occur but also
    recognizes that the economy historically has come back from those
    recessions. Therefore, SM&R believes that the United States economy will
    continue to grow, that the political environment will continue to be
    relatively stable, and that the financial markets will continue to function
    in a reasonably orderly fashion. As long as these factors occur, SM&R
    believes that there is a reasonable likelihood the Balanced Fund can reach
    its goal of preservation of capital while at the same time investing in
    common stock.
 
    SM&R, through an ongoing program of asset allocation, will determine the
    appropriate level of equity holding consistent with SM&R's outlook and
    evaluation of trends in the economy and the financial markets. The Balanced
    Fund determines its level of commitment to common stocks and specific common
    stock investments as a result of this process. For example, within an
    environment of rising inflation, common stocks historically have preserved
    their value better than bonds; therefore, inclusion of common stocks could
    tend to conserve principal better than a portfolio consisting entirely of
    bonds and other debt obligations. In addition, within an environment of
    accelerating growth in the economy, common stocks historically have
    conserved their value better than bonds in part due to a rise in interest
    rates that occur coincidentally with accelerating growth and profitability
    of the companies.

RISK FACTORS
- --------------------------------------------------------------------------------
 
The following discussion relates to all three 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 stocks 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.
 
STOCK INVESTMENT RISKS. Because each fund invests a substantial portion of its
assets in stocks, 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. Stock 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 that company's stock price (for example, poor earnings,
    loss of major customers, or major litigation). The funds cannot always
    predict the factors that will affect a stock'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 any one company and by not holding a substantial amount
    of the stock of any one company.
 
    For the Growth Fund and the Equity Income Fund, the portfolio managers
    decide to overweight or underweight certain industry sectors and to purchase
    individual stocks based on their assessment of the future growth or income
    prospects of an industry sector or particular stock. If certain industries
    or investments do not perform as a fund expects (I.E., do not grow in value
    or produce dividend income as expected), that fund could underperform its
    peers or lose money.
 
    The Growth Fund is generally considered more aggressive than the Equity
    Income and Balanced Funds because it invests for capital appreciation in
    common stocks, emphasizing "growth" stocks that tend to be more volatile
    than other investments. Investors in the Growth Fund should expect greater
    fluctuations in share price, yield, and total return than with less
    aggressive funds.
 
                                       21
<PAGE>
DEBT SECURITIES RISKS. Debt securities are subject to changes in their values
due to changes in prevailing interest rates. 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. 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. The magnitude of these
    fluctuations will often be greater for longer-term debt securities than
    shorter-term debt securities.
 
    The funds could lose money if any bonds they own are downgraded in credit
    rating or go into default. In general, lower-rated bonds, such as junk
    bonds, have higher credit risks. The Growth Fund is the only fund permitted
    to invest in junk bonds. Junk bonds have additional risks, including
    limitations on a fund's ability to re-sell the lower-rated debt securities
    and less readily available market quotations for such securities. If there
    are not readily available market quotations for a debt security, its value
    is determined largely by the investment manager's judgment. When and if the
    debt security is sold, the investment manager may find that its estimation
    of the debt security's value is substantially different than the actual
    price at which it can be sold. Moreover, substantial redemptions of fund
    shares could require a fund to sell portfolio securities at a time when a
    sale might not be favorable.
 
SMALLER COMPANY RISKS. Smaller companies in which each of the funds may invest
may involve greater risks than large established companies. Such smaller
    companies may have limited product lines, markets, financial resources, and
    management depth. Their securities may trade less frequently and in more
    limited volume than the securities of larger or more established companies.
    Smaller companies may also be more vulnerable than larger companies to
    adverse business or market developments. As a result, the prices of smaller
    companies may fluctuate to a greater degree than the prices of securities of
    larger companies.
 
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"). You should carefully review all account statements
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.
    P.O. Box 58969
    Houston, Texas 77258-8969
 
Investors whose shares are held in the name of a broker-dealer or other party
are not shareholders of record and, therefore, may not be able to utilize
services available only to shareholders of record.
 
Certificates are not issued for shares of the funds. 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.
 
OPENING AN ACCOUNT: To purchase shares, you must submit a completed account
application which includes the purchaser suitability form. If you would like to
    take advantage of the electronic services available, please complete the
    applicable Special Investor Services 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 for
each fund is $100. The minimum amount of any subsequent purchase is $20 for each
    fund. We waive these initial investment minimums when 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
 
                                       23
<PAGE>
    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 Growth 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 day the New York Stock Exchange (the "Exchange") is open for regular
    trading. 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.") 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). We
calculate net asset value once each day at the close of regular trading on the
    Exchange (currently 3:00 p.m. Central Time). In the event the Exchange
    closes early on a particular day we will determine the net asset value of
    each fund as of the close of the Exchange that day. 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 day the Exchange is open for regular
    trading, we will execute purchases and redemptions at the next 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 or on any day that
    the Exchange is closed, 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.
 
                                       24

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 funds offers other services and plans designed to facilitate investments. At
this time, there is no charge to you for these services. The funds 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, broker-dealer 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 Special Investor Services
    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).
 
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 employees may initially invest a minimum
    of $100 ($20 per individual) in the funds followed by additional payments of
    at least $20 for each individual investing under a single payroll deduction
    plan. Any such plan may be terminated by SM&R or the shareholder at any time
    upon sixty (60) days written notice. Contact SM&R for further information
    regarding these plans.
 
TELEPHONE SERVICES. You can only use telephone services for transaction amounts
of $500 or more. You can take advantage of this service by completing the
    appropriate Special Investor Services sections of the account application
    when opening your account. Through this service, you will be able to
    purchase additional shares for an existing SM&R mutual fund account by ACH.
    You may also use the telephone services to 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 for more information. PLEASE NOTE THAT THE
    TELEPHONE REDEMPTION OPTION IS NOT AVAILABLE TO RETIREMENT PLANS.
 
                                       25
<PAGE>
    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).
 
    During times of economic turmoil or market volatility or during periods of
    severe weather or a natural disaster, it may be difficult to contact SM&R by
    telephone to institute a redemption or exchange.
 
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.
 
EXCHANGE PRIVILEGE. As an investor in a fund, you may be permitted to exchange
shares that you own in a fund with shares of some of the other mutual funds
    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 AND WHETHER AN EXCHANGE IS
    PERMITTED.
 
    WE MAY TERMINATE OR CHANGE THE TERMS OF ANY EXCHANGE OFFER AT ANY TIME.
 
    You may exchange Class A, B, or C shares of a fund, without an exchange fee
    or sales charge, for shares of the corresponding class of another fund
    managed by SM&R. You also may exchange your Class A or B shares for shares
    of SM&R Investments, Inc.'s Primary Fund and 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 5 years in
       the case of Class B shares), and
 
     - you meet any minimum investment requirement for the shares you wish to
       acquire.
 
    You CANNOT exchange Class C shares for shares of the Money Market Fund or
    Primary Fund.
 
    We waive any sales charges on Class A and Class T shares acquired through an
    exchange if you previously paid a sales charge on amounts invested in those
    shares. For example, assume you purchase Class A shares of the Growth Fund.
    You then exchange your Class A shares for shares of the SM&R Investments,
    Inc. Money Market Fund. Later, you re-exchange those
 
                                       26
<PAGE>
    shares of the Money Market Fund for Class A shares of the Equity Income
    Fund. We would not impose any sales charge upon the re-exchange into Class A
    shares because you previously paid a sales charge on amounts invested in
    those shares. In other words, we will never impose a front-end sales charge
    on the same investment TWICE.
 
    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 that are registered in the
           same name, address and, if applicable, taxpayer identification
           number;
 
       (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 a written exchange must meet the minimum
           investment requirement applicable to the shares of the fund that you
           would acquire through the exchange;
 
       (d) the minimum dollar amount of a telephone exchange is $500;
 
       (e) SM&R must have received full payment for the shares being exchanged;
 
       (f) 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);
 
       (g) any shares that you wish to exchange must have been held for at least
           ten (10) business days; 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. The conversion benefits shareholders
    because Class A shares are subject to a lower ongoing 12b-1 fee. If an
    investor exchanges Class B shares of a fund for Class B shares of another
    fund managed by SM&R,
 
                                       27
<PAGE>
    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 funds and raise the funds' 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 invest in shares of the 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. SM&R acts as trustee or
custodian for IRAs, SEPs, and TSAs for the funds. 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 funds and will be automatically deducted
from each account. An individual considering a retirement plan may wish to
consult with an attorney or tax adviser.
 
DIVIDENDS, DISTRIBUTIONS, AND TAXES
 
DIVIDENDS. The Equity Income and Balanced Funds will pay dividends from
investment income, if any, quarterly, generally during the months of March,
    June, September and December, and distribute capital gains, if any, in
    December. The Growth Fund will pay dividends from investment income, if any,
    semi-annually during the months of June and December and distribute capital
    gains, if any, in December. Dividends from net investment income may include
    net short-term capital gains, if any.
 
    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.
 
                                       28
<PAGE>
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 funds. 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 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. Corporations may be entitled to take a dividends-received
    deduction for a portion of certain dividends they receive. 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.
 
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 funds 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 the 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., P.O. Box 58969, Houston, Texas 77258-8969.
 
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.
 
                                       29
<PAGE>
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. Telephone
    privileges are not available to shareholders automatically. 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 proceeds of the redemption are $500 or more and do not exceed
           $25,000; and
 
       (d) the security procedures discussed under "Special Purchase Plans And
           Services-- Exchange Privilege" have been met.
 
    These instructions may be changed only in writing, accompanied by a
    signature guarantee and additional documentation may be required for
    corporations.
 
FAX REDEMPTIONS. You may request redemptions by fax as long as they meet the
requirements stated (a)-(c) under Telephone Redemptions above.
 
SYSTEMATIC WITHDRAWAL PLAN. Each fund 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 funds because of the sales charge or
    CDSC (as applicable) involved in additional purchases. See "Class B Waivers
    of Contingent Deferred Sales Charges" for a discussion of the CDSC waivers
    available. 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. 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.
 
                                       30
<PAGE>
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.
 
    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 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;
 
       (2) any required signature guarantees (see "Signature Guarantees" below);
           and
 
       (3) 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 SM&R 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 fund 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 fund or transfer agent.
 
                                       31
<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 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.
 
REDEMPTION OF SMALL ACCOUNTS. The funds reserve 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 $500. You will be notified
    that the value of your account is less than the required minimum and allowed
    at least 60 days to make an additional investment to increase the value of
    your account above the required minimum. The funds may, from time to time,
    change such required minimum investment.
 
RIGHTS RESERVED BY THE FUNDS. The funds, acting directly or through SM&R,
reserve 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 or has
       occurred;
 
     - 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;

       reside at the same address.

THE FUNDS AND MANAGEMENT
- --------------------------------------------------------------------------------
 
INVESTMENT ADVISER
 
Each fund's Board of Directors has delegated to Securities Management and
Research, Inc. ("SM&R"), the fund's investment adviser, the management of the
fund's 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. While the use of this
combined Prospectus subjects each fund to possible liability as the result of
statements or omissions regarding another fund, the Board of Directors of each
fund considers the benefits to the respective fund of using a combined
Prospectus to outweigh the risk.
 
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 banks, employee benefit plans, other
investment companies, banks, foundations and endowment funds.
 
ADVISORY AGREEMENTS
 
GROWTH FUND. We deduct an investment advisory fee from the value of the shares
each day. We calculate this fee for the Growth Fund at the annual rate as
follows:

</TABLE>
 
We adjust the basic advisory fee rate by comparing the fund's investment
performance during the previous thirty-six (36) months with the investment
performance of the Lipper Growth Fund Index (the "Lipper Index") published by
Lipper Analytical Services, Inc. over the same period. Specifically, we adjust
the basic advisory fee each month by adding to or subtracting from such rate,
when appropriate, the applicable performance adjustment amount percentage shown
in the table below. The resulting advisory fee rate is then applied to the
average daily net asset value of the fund for the succeeding month. The advisory
fee for such month will be one-twelfth ( 1/12th) of the resulting dollar figure.

Funds for the fiscal year ended December 31, 1997 of 0.60%, 0.69%, and 0.75%,

may be higher than the fees paid by other mutual funds, but each fund believes
its fees are comparable to those paid by funds with the same or similar
investment objective.

investment advisory services to the funds. While the following individual is

The following financial highlights table is intended to help you understand the
Growth 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 Growth 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 Growth Fund, which for the year ended through December 31, 1997 have been
audited by Tait, Weller & Baker, independent auditors, whose report, along with
the Growth Fund's financial statements, are incorporated by reference into the
Statement of Additional Information, which is available upon request. The
information for years ending December 31, 1996 and prior, has been audited by
the Growth Fund's former independent auditors. The information for the six month
period ended June 30, 1998 was derived from unaudited financial statements of

FINANCIAL HIGHLIGHTS                                               BALANCED FUND
- --------------------------------------------------------------------------------
 
The following financial highlights table is intended to help you understand the
Balanced Fund's financial performance for the past five years. Certain
information reflects financial results for a single Balanced 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 Balanced 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 Balanced Fund, which
for the year ended through December 31, 1997 have been audited by Tait, Weller &
Baker, independent auditors, whose report, along with the Balanced Fund's
financial statements, are incorporated by reference into the Statement of
Additional Information, which is available upon request. The information for
years ending December 31, 1996 and prior, has been audited by the Balanced
Fund's former independent auditors. The information for the six month period
ended June 30, 1998 was derived from unaudited financial statements of the
Balanced Fund.

APPENDIX A
 
(Description of Ratings Used in Prospectus)
- --------------------------------------------------------------------------------
 
BOND RATINGS
 
DESCRIPTION OF STANDARD & POOR'S CORPORATION'S LONG-TERM BOND (BONDS THAT EXTEND
LONGER THAN ONE YEAR) 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 impair the obligor's capacity or
      willingness to meet its financial commitment on the obligation.
 
DESCRIPTION OF MOODY'S INVESTOR'S SERVICE, INC.'S LONG-TERM BOND (BONDS THAT
EXTEND LONGER THAN ONE YEAR) 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 larger than the 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.
 
                                      A-1
<PAGE>
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.
 
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.
 
PREFERRED STOCK RATING
 
DESCRIPTION OF STANDARD & POOR'S CORPORATION'S PREFERRED STOCK RATING:
 
AAA  This is the highest rating that may be assigned by Standard & Poor's to a
     preferred stock issue and indicates an extremely strong capacity to pay the
     preferred stock obligations.
 
AA   A preferred stock issue rated "AA" also qualifies as a high-quality,
     fixed-income security. The capacity to pay preferred stock obligations is
     very strong, although not as overwhelmingly as for issues rated "AAA."
 
A    An issue rated "A" is backed by a sound capacity to pay the preferred stock
     obligations, although it is somewhat more susceptible to the adverse
     effects of changes in circumstances and economic conditions.
 
BBB  An issue rated "BBB" is regarded as backed by an adequate capacity to pay
     the preferred stock obligations. Whereas it normally exhibits adequate
     protection parameters, adverse economic conditions or changing
     circumstances are more likely to lead to a weakened capacity to make
     payments for a preferred stock in this category than for issues in the "A"
     category.
 
BB   Preferred stock rated "BB," "B," and "CCC" are regarded, on balance, as
     predominantly speculative with
B     respect to the issuer's capacity to pay preferred stock obligations. "BB"
      indicates the lowest degree of speculation
CCC  and "CCC"' the highest. While such issues will likely have some quality and
     protective characteristics, these are outweighed by large uncertainties or
     major risk exposures to adverse conditions.
 
                                      A-2
<PAGE>
DESCRIPTION OF MOODY'S INVESTORS SERVICE, INC.'S PREFERRED STOCK RATING:
 
aaa   An issue which is rated "aaa" is considered to be a top-quality preferred
      stock. This rating indicates good asset protection and the least risk of
      dividend impairment within the universe of preferred stocks.
 
aa    An issue which is rated "aa" is considered a high grade preferred stock.
      This rating indicates that there is a reasonable assurance the earnings
      and asset protection will remain relatively well maintained in the
      foreseeable future.
 
a     An issue which is rated "a" is considered to be an upper-medium grade
      preferred stock. While risks are judged to be somewhat greater than in the
      "aaa" and "aa" classification, earnings and asset protection are,
      nevertheless, expected to be maintained at adequate levels.
 
baa   An issue which is rated "baa" is considered to be a medium-grade preferred
      stock, neither highly protected nor poorly secured. Earnings and asset
      protection appear adequate at present but may be questionable over any
      great length of time.
 
ba    An issue which is rated "ba" is considered to have speculative elements
      and its future cannot be considered well assured. Earnings and asset
      protection may be very moderate and not well safeguarded during adverse
      periods. Uncertainty of position characterizes preferred stocks in this
      class.
 
b     An issue which is rated "b" generally lacks the characteristics of a
      desirable investment. Assurance of dividend payments and maintenance of
      other terms of the issue over any long period of time may be small.
 
FEDERAL FUNDS
 
As used in this Prospectus and in the Funds' Statement of Additional
Information, "Federal Funds" means a commercial bank's deposits in a Federal
Reserve Bank which can be transferred from one member bank's account to that of
another member bank on the same day. Federal Funds are considered to be
immediately available funds.

INVESTOR RISK TOLERANCE QUIZ

The results of this short quiz won't be conclusive, of course. But it may give
you some insight into how much risk you can or should build into your personal
investment plan. Risk is one of the factors you need to consider before making
investment decisions. Consult with your registered representative to guide you
in the use of the questionnaire.

     1.   WHAT DO YOU THINK ABOUT INVESTING?
          / / a. I prefer as little risk as possible to get a stable investment.
          / / b. I prefer a balanced approach to risk and return.
          / / c. I can accept more risk to get the highest possible return.

     2.   WHAT DO YOU THINK ABOUT INVESTING IN STOCKS COMPARED TO BONDS AND
          CASH?
          / / a. I prefer cash investments over stocks and bonds even though
                 the return may be less.
          / / b. I like a mix of stocks and bonds to give me a balanced
                 investment.
          / / c. I like stocks because of the opportunity for higher returns
                 even though the risk is greater.

     3.   WHAT DO YOU THINK ABOUT FLUCTUATIONS IN YOUR ACCOUNT?
          / / a. I want to reduce fluctuations even though my investment return
                 may be less.
          / / b. I can tolerate only moderate fluctuations to gain favorable
                 returns.
          / / c. I can tolerate larger fluctuations in order to increase the
                 potential for higher returns.

     4.   WHAT DO YOU THINK ABOUT INFLATION AND ITS IMPACT ON YOUR INVESTMENTS?
          / / a. I am satisfied if my returns only keep up with inflation.
          / / b. I am happy if my investment returns only slightly beat
                 inflation.
          / / c. I want my investment returns to get a higher return than the
                 rate of inflation.

     5.   HOW MANY YEARS BEFORE YOU NEED THE MONEY?
          / / a. 1-5 years
          / / b. 6-10 years
          / / c. 11 years or more

SCORING:
For an "a" answer give yourself 1 point, for each "b", 3pts., for each "c",
5pts.

5-12 POINTS 
CONSERVATIVE INVESTING:
The goal is to preserve the original investment while achieving a small, but 
predictable gain.

13-21 POINTS 
MODERATE INVESTING:
The goal is to expect some ups-and-downs in return for a good gain over time.

22-25 POINTS
AGGRESSIVE INVESTING:
The goal is to accept larger short-term losses than most investors in return for
the possibility of substantial long-term gains.


LOW       MODERATE       HIGH

     POTENTIAL REWARD/RISK

Risk is defined as volatility of returns. A high-risk investment policy provides
an opportunity to achieve greater returns (reward) than a low-risk investment
policy. A high-risk policy also creates the possibility of achieving lower
returns than a low-risk investment policy, so it is said that a high-risk policy
is more volatile. Before making any investment decision, you should obtain and
carefully read the current prospectus for complete information, including all
fees and expenses. When investing in securities, shares may be worth more or
less than the purchase price and there is no guarantee against the loss of
principal and profit.

RISK/RETURN SUMMARY                                             SM&R GROWTH FUND
- -------------------------------------------------------------------
 
GROWTH FUND'S INVESTMENT OBJECTIVE
                   The Growth Fund seeks long-term capital
                   growth by investing primarily in common stocks that provide
                   an opportunity for capital appreciation over time.
 
GROWTH FUND'S PRINCIPAL INVESTMENT STRATEGIES
                   The Growth Fund normally invests at least 85%
                   of its total assets in common stocks. In selecting stocks,
                   this fund:
                   - chooses the stocks of financially sound companies that have
                     a proven ability to make and sustain a profit over time,
                     and
                   - places an emphasis on companies with growth potential.
 
                   The Growth Fund generally purchases a higher proportion of
                   stocks (relative to their market weight) from those sectors
                   of the market with higher growth prospects, referred to as
                   "overweighting." Examples of sectors with higher growth
                   prospects currently include technology, healthcare, and
                   consumer staples. On the other hand, the fund generally
                   purchases a smaller proportion of stocks (relative to their
                   market weight) from sectors of the market with below average
                   growth characteristics (for example, utilities, basic
                   materials, and communications services), referred to as
                   "underweighting."
 
                   The Growth Fund may also invest in debt obligations (such as
                   convertible preferred stocks, debentures, and notes),
                   including below investment grade bonds ("junk" bonds).
 
PRINCIPAL RISKS OF INVESTING IN THE GROWTH FUND
                   You could lose money on your investment in the
                   Growth Fund, or it could underperform other investments, if
                   any of the following occurs:
                   - the stock market goes down
 
                                       1

RISK/RETURN SUMMARY                                       SM&R GROWTH FUND, INC.
- -------------------------------------------------------------------
 
                   - the investment decisions of management (such as sector
                     overweighting and underweighting and individual stock
                     selection) do not achieve the desired results
                   - interest rates increase
                   - issuers of debt obligations default or are unable to pay
                     amounts due
 
                   Investments by the Growth Fund in smaller companies may
                   involve greater risks than larger established companies.
 
WHO MAY WANT TO INVEST IN THE GROWTH FUND
 
                   This fund may be appropriate if you:
                   - have long time horizons (ten years or more)
                   - are willing to accept higher short-term risk along with
                     higher potential long-term returns
                   - want to diversify your portfolio
                   - are investing for retirement or other goals that are many
                     years in the future
 
                   This fund may NOT be appropriate:
                   - if you are investing with a shorter time horizon
                   - if you are uncomfortable with an investment that will go up
                     and down in value
                   - as your complete portfolio

- -------------------------------------------------------------------
 
EQUITY INCOME FUND'S INVESTMENT OBJECTIVE
                   The Equity Income Fund seeks current income
                   with a secondary objective of long-term capital appreciation.
 
EQUITY INCOME FUND'S PRINCIPAL INVESTMENT STRATEGIES
                   The Equity Income Fund normally invests at
                   least 75% of its assets in equity securities. This fund also
                   invests in preferred stocks and investment grade debt
                   securities (such as publicly traded corporate bonds,
                   debentures, notes, commercial paper, repurchase agreements,
                   and certificates of deposit). In selecting common and
                   preferred stocks, the fund focuses on companies with
                   consistent and increasing dividend payment histories and
                   future earnings potential sufficient to continue such
                   dividend payments. This fund's goal is to maintain a
                   portfolio dividend yield (before fees and expenses) at least
                   50% greater than that of the S&P 500 Index.
 
                   The Equity Income Fund generally purchases a higher
                   proportion of stocks (relative to their market weight) from
                   those sectors of the market with greater dividend prospects,
                   referred to as "overweighting." Examples of sectors with
                   greater dividend prospects currently include financial
                   companies like banks, insurance companies, and real estate
                   investment trusts. On the other hand, the fund generally
                   purchases a smaller proportion of stocks (relative to their
                   market weight) from sectors of the market with below average
                   dividend yields (such as technology and consumer staples),
                   referred to as "underweighting."

PRINCIPAL RISKS OF INVESTING IN THE EQUITY INCOME FUND
                   You could lose money on your investment in the
                   Equity Income Fund, or it could underperform other
                   investments, if any of the following occurs:
                   - the stock market goes down and/or interest rates increase
                   - the investment decisions of management (such as sector

                     amounts due
                   - the fund cannot find a buyer for securities
 
                   Investments by the Equity Income Fund in smaller companies
                   may involve greater risks than larger established companies.
 
WHO MAY WANT TO INVEST IN THE EQUITY INCOME FUND
                   This fund may be appropriate if you:
                   - are looking for a fund that has both growth and income
                     components
                   - are seeking to protect the purchasing power of your money
                     while retaining the potential for growth and reducing
                     exposure to the volatility of the market
                   - are willing to accept higher short-term risk along with
                     higher potential long-term returns
                   - are retired or nearing retirement
 
                   This fund may NOT be appropriate if you:
                   - are investing for maximum return over a long time horizon
                   - require a high degree of stability of your principal
                   - desire your return to be either ordinary income or capital
                     gains, but not both

RISK/RETURN SUMMARY                                     SM&R BALANCED FUND, INC.
- -------------------------------------------------------------------
 
BALANCED FUND'S INVESTMENT OBJECTIVE
                   The Balanced Fund seeks to conserve principal,
                   produce current income, and achieve long-term capital
                   appreciation.
 
BALANCED FUND'S PRINCIPAL INVESTMENT STRATEGIES
                   The Balanced Fund uses a "balanced" approach
                   by investing part of the assets in common stocks and the
                   remainder in a combination of high-grade bonds, convertible
                   bonds, and money market instruments. The ratio of stocks to
                   bonds changes in response to changing economic conditions.
                   This flexibility may help to reduce price volatility.
 
                   This fund's goal is relative stability of principal through a
                   balance of stocks, bonds, and cash. The stocks are
                   diversified and are selected based upon two models. One model
                   is based on profitability measurements and the other model is
                   based on the corporation's return on invested cash. The
                   bonds, meanwhile, may serve as a stabilizing force during
                   times of eroding stock market value, as well as provide a
                   fixed income payment stream. The fund invests at least 25% of
                   assets in fixed income securities, all of which are rated BBB
                   or better (investment grade). Common stocks purchased by the
                   fund will have a market capitalization of at least $100
                   million and be listed on a national exchange.
 
PRINCIPAL RISKS OF INVESTING IN THE BALANCED FUND
                   You could lose money on your investment in the
                   Balanced Fund, or it could underperform other investments, if
                   any of the following occurs:
                   - interest rates increase or the stock market goes down
                   - issuers of debt obligations default or are unable to pay
                     amounts due
                   - the investment decisions of management do not achieve the
                     desired results
 
                   Investments by the Balanced Fund in smaller companies may
                   involve greater risks than larger established companies.

                   This fund may be appropriate if you:
                   - are seeking supplemental income and conservation of the
                     purchasing power of your capital
                   - are looking for a more conservative alternative to a
                     growth-oriented fund
                   - want a well-diversified and relatively stable investment
                     allocation
                   - need a core investment
                   - are retired or nearing retirement
 
                   This fund may NOT be appropriate if you:
                   - are investing for maximum return over a long time horizon
                   - desire your return to be either ordinary income or capital
                     gains, but not both
                   - require a high degree of stability of your principal

RISK/RETURN SUMMARY
- -------------------------------------------------------------------
 
TYPES OF INVESTMENT RISK
 
As indicated above, each of the three funds is subject to the following types of
risks to varying degrees:
 
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. THIS RISK APPLIES TO
ALL OF THE FUNDS, BUT MAY HAVE A GREATER IMPACT ON THE BALANCED AND EQUITY
INCOME FUNDS.
 
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. THIS RISK APPLIES TO ALL OF THE FUNDS, BUT MAY HAVE A GREATER IMPACT ON
THE BALANCED AND EQUITY INCOME FUNDS.
 
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.

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 over a ten year period, and
- - by showing how each fund's average annual returns for 1, 5, and 10 years
  compare to those of both a broad-based securities market index and an index of
  funds with similar investment objectives.
 
The returns shown do not reflect any sales loads that would be imposed on the
purchase or sale of any shares and are based on an investment in the funds prior
to the creation of multiple classes of shares. We created the multiple classes
of shares on January 1, 1999.
 
Past performance is not necessarily an indication of how the funds will perform
in the future.

RISK/RETURN SUMMARY
- ------------------------------------------------
 
(4) "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 Growth, Equity Income, and Balanced Fund for the fiscal year
    ended December 31, 1997.
 
(5) 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% 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. During the fiscal year
   ended December 31, 1997, SM&R waived management fees of 0.10% for the
   Balanced Fund.
 
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:

Because there are no deferred sales charges or redemption fees, you would pay
the same expenses, based on these assumptions, if you did NOT redeem your
shares.

SHARES OF THE FUNDS
- -------------------------------------------------------------------
 
The funds ("we") offer Class T shares through this Prospectus. The 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 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 Securities Management and Research, Inc. ("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 class alternatives and choose the one that fits your
individual circumstances at the lowest level of fees. FOR MORE INFORMATION ON

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 a 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 Growth 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 Equity Income Fund.
 
  - If you are a designated person listed in (a)-(i) 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 that impose a front-end sales charge. 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;
 
    (4) 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
 
    (5) Employees (or employers on behalf of employees) under any employee
        benefit plan not qualified under Section 401 of the Internal Revenue
        Code.
 
Purchases in connection with employee benefit plans not qualified under Section
401 of the Internal Revenue Code will qualify for the above quantity discounts
only if the fund 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 fund's prospectus available to
individual investors or employees, forwarding investments by such employees to
the funds, and the like.
 
                                       16
<PAGE>
DISCOUNTS THROUGH A RIGHT OF ACCUMULATION. If you already own Class A or Class T
shares of a fund managed by SM&R on which you paid a front-end sales charge, you
may be able to receive a discount when you buy additional shares. The current
net asset value for the shares you already own may be "accumulated"--I.E.,
combined together with the dollar amount being invested--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.
 
THE EDUCATION FUNDING INVESTMENT ACCOUNT PROGRAM. The Education Funding
Investment Account Program is a service expressly created to help investors
accumulate funds for their children's or grandchildren's college education by
reducing the standard sales charge for investments of less than $50,000 through
this Program. The following breakpoints apply to purchases of Class T shares
made by individuals investing in the funds through the use of The Education
Funding Investment Account Program, as well as the Education IRA:

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. More investment information is in the Statement of Additional
Information. 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.
 
SM&R GROWTH FUND, INC.
(FORMERLY NAMED AMERICAN NATIONAL GROWTH FUND, INC.)
 
The Growth Fund considers its portfolio investments and the composition of its
total portfolio from the viewpoint of potential capital appreciation. The Growth
Fund adjusts this composition from time to time in light of current conditions.
Under normal conditions, the Growth Fund invests at least 85% of its total
assets in common stocks.
 
The Growth Fund invests in the stocks of financially sound companies that have a
proven ability to make and sustain a profit over time. Management places an
emphasis on companies with growth potential. The Growth Fund does not employ
exotic investment strategies, such as using options and futures.
 
                                       18
<PAGE>
We identify candidate stock investments based on (1) low equity valuation
(price) and (2) improving earnings. Then, we evaluate each candidate stock on a
fundamental basis by examining past financial performance, managerial skill and
foresight, and relative valuation to industry peers and the market as a whole.
We utilize this combination of disciplines and human judgement to drive our
stock selection process. We believe in evaluating each company's prospects as
opposed to relying on broad forecasts of industry prospects. We do not attempt
to time economic, market, style or capitalization cycles. Diversification, or
weighting of individual economic sectors, is also dictated by a combination of
disciplines and human judgement to varying degrees. We believe in never having
less than half or more than double the market weighting in any one sector. The
Growth Fund limits cash to 15% of its assets unless circumstances dictate
otherwise.
 
Because of the Growth Fund's goal of seeking long-term capital growth, certain
sectors of the market will have greater weight in the Growth Fund's portfolio
while other sectors of the market will have lower representation. For example,
the Growth Fund generally overweights the technology sector, which represents
approximately 15% of the Standard & Poor's 500 Index, in the portfolio relative
to its market weight. This overweighting reflects the higher growth prospects of
technology companies relative to the average company in the market. At varying
times, we may also overweight other sectors of the market providing above
average growth prospects, like healthcare and consumer staples.
 
Conversely, the Growth Fund generally underrepresents certain sectors of the
market in its portfolio that tend to have below average growth characteristics,
like utilities, basic materials, and communications services. As a result of
such strategic overweighting and underweighting, the Growth Fund's performance
may differ substantially from broad market indexes like the S&P 500 and tend to
incur more price volatility than these indexes.
 
The Growth Fund may invest in convertible preferred stocks rated at least "B" by
Standard and Poor's Corporation ("S&P") or at least "b" by Moody's Investors
Service, Inc. ("Moody's") preferred stock ratings, and convertible debentures
and notes rated at least "B" by S&P and Moody's corporate bond ratings.
Investments in convertible securities having these ratings may involve greater
risks than convertible securities having higher ratings.
 
                                       19
<PAGE>
The proportion of assets invested in any particular type of security can be
expected to vary, depending on SM&R's appraisal of market and economic
conditions. Common stocks and convertible securities purchased will be of
companies that SM&R believes will provide an opportunity for capital
appreciation. On a temporary basis, the Growth Fund may invest 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, in certificates of deposit in domestic banks and savings
institutions having at least $1 billion of total assets, and in repurchase
agreements.
 
SM&R EQUITY INCOME FUND, INC.
(FORMERLY NAMED AMERICAN NATIONAL INCOME FUND, INC.)
 
The Equity Income Fund considers its portfolio investments and the composition
of its total portfolio not only from the viewpoint of present and potential
yield, but also from the viewpoint of potential capital appreciation. We adjust
this composition of portfolio investments from time to time to best accomplish
the Equity Income Fund's investment objectives under current conditions.
 
In pursuit of its objectives, the Equity Income Fund will invest in common
stocks, preferred stocks, and marketable debt securities selected in accordance
with its investment objectives. Common and preferred stocks purchased will
generally be of companies with consistent and increasing dividend payment
histories that SM&R believes will have further earnings potential sufficient to
continue such dividend payments. Debt securities include publicly traded
corporate bonds, debentures, notes, commercial paper, repurchase agreements, and
certificates of deposit in domestic banks and savings institutions having at
least $1 billion of total assets. The proportion of assets invested in any
particular type of security can be expected to vary, depending on SM&R's
appraisal of market and economic conditions. Under normal conditions, the Equity
Income Fund will invest at least 75% of its assets in equity securities rather
than debt securities.
 
We view common stocks, as well as investments in preferred stocks and bonds
convertible into common stock, from their potential for capital appreciation in
addition to their current and potential income yield. Our goal is to maintain a
portfolio dividend yield (before fees and expenses) at least 50% greater than
that of the S&P 500 Index.

less than half or more than double the market weighting in any one sector. Cash
is limited to 15% of the fund unless circumstances dictate otherwise.
 
Certain sectors of the market will have greater weight in the Equity Income
Fund's portfolio while other sectors of the market will have lower
representation. For example, the Equity Income Fund generally overweights the
finance sector in its portfolio relative to that sector's market weight (which
is approximately 16% of the Standard & Poor's 500 Index). This reflects the
greater dividend prospects of financial companies like banks, insurance
companies, and real estate investment trusts as compared to the average company
in the market. At varying times, we may also overweight other sectors of the
market that provide above average dividend prospects, like utilities and energy.
 
Conversely, the Equity Income Fund generally underrepresents certain sectors of
the market tending to have below average dividend yields, like technology,
consumer staples, and healthcare. As a result of such strategic overweighting
and underweighting, the Equity Income Fund's performance may differ
substantially from broad market indexes like the S&P 500.
 
Corporate debt obligations purchased by the Equity Income Fund will consist only
of obligations rated either Baa or better by Moody's or BBB or better by S&P.
Bonds which are rated Baa by Moody's are considered as medium grade obligations,
that is, they are neither highly protected nor poorly secured. Bonds rated BBB
by S&P are regarded as having an adequate capacity to pay interest and repay
principal. Commercial paper and notes will consist only of direct obligations of
corporations whose bonds and/or debentures are rated as set forth above.

SM&R BALANCED FUND, INC.
(FORMERLY NAMED TRIFLEX FUND, INC.)
 
The Balanced Fund uses a "balanced" approach by investing part of its assets in
stocks of well-known companies and the remainder in a combination of high-grade
bonds, bonds convertible into the common stock of the issuing corporations, and
money market instruments. We change the ratio of stocks to bonds in response to
changing economic conditions. This flexibility helps to reduce price volatility.
 
The Balanced Fund's goal is relative stability of principal through a balance of
stocks, bonds, and cash. The stocks serve to capture the benefits that ownership
in corporate America brings. The bonds, meanwhile, can serve as a stabilizing
force during times of eroding stock market value, as well as provide a fixed
income payment stream into the portfolio.
 
The Balanced Fund will only purchase common stocks and convertible securities of
corporations having a market capitalization of at least $100 million, an
operating history of at least three (3) years, and a listing on the New York
Stock Exchange, American Stock Exchange, or Over-The-Counter markets. The
Balanced Fund will only purchase corporate bonds rated either Baa or better by
Moody's or BBB or better by S&P. Bonds which are rated Baa by Moody's are
considered as medium grade obligations, that is, they are neither highly
protected nor poorly secured. Bonds rated BBB by S&P are regarded as having an
adequate capacity to pay interest and repay principal. Commercial paper and
notes will consist only of direct obligations of corporations whose bonds and/or
debentures are rated as set forth above. The Balanced Fund may also invest in
repurchase agreements. This balanced investment policy is intended to reduce
risk and to obtain results in keeping with the Balanced Fund's objectives.
 
The Balanced Fund will invest in fixed-income securities and equity securities
as described above. However, the Balanced Fund will sometimes be more heavily
invested in equity securities and at other times it will be more heavily
invested in fixed-income securities, depending on management's appraisal of
market and economic conditions. SM&R believes that a fund that is wholly
invested in fixed-income securities carries a large interest rate risk. Interest
rate risk is the uncertainty about losses due to changes in the rate of
 
                                       22
<PAGE>
interest on debt instruments. The major interest rate risk for investors,
however, is not in the interest rate itself, but in the change in the market
price of bonds that results from changes in the prevailing interest rate. Higher
interest rates would mean lower bond prices and lower net asset value for the
Balanced Fund's shareholders assuming no change in its current investment
objective and portfolio. Diversifying the Balanced Fund's portfolio with
investments such as commercial paper, convertible securities, and common stocks
may reduce the decline in value attributable to the increase in interest rate
and resulting decrease in the market value of bonds and may reduce the interest
rate risk. However, stock prices also fluctuate in response to a number of
factors, including changes in general level of interest rates, economic and
political developments, and other factors which impact individual companies or
specific types of companies. Such market risks cannot be avoided but can be
limited through a program of diversification and a careful and consistent
evaluation of trends in the capital market and fundamental analysis of
individual equity holdings.
 
The Balanced Fund's goal of preservation of capital while owning common stocks
depends on various factors, including the sustained long-term growth of the
United States economy. SM&R recognizes that recessions occur but also recognizes
that the economy historically has come back from those recessions. Therefore,
SM&R believes that the United States economy will continue to grow, that the
political environment will continue to be relatively stable, and that the
financial markets will continue to function in a reasonably orderly fashion. As
long as these factors occur, SM&R believes that there is a reasonable likelihood
the Balanced Fund can reach its goal of preservation of capital while at the
same time investing in common stock.
 
SM&R, through an ongoing program of asset allocation, will determine the
appropriate level of equity holding consistent with SM&R's outlook and
evaluation of trends in the economy and the financial markets. The Balanced Fund
determines its level of commitment to common stocks and specific common stock
investments as a result of this process. For example, within an environment of
rising inflation, common stocks historically have preserved their value better
than bonds; therefore, inclusion of common stocks could tend to conserve
principal better than a portfolio consisting entirely of bonds and
 
                                       23
<PAGE>
other debt obligations. In addition, within an environment of accelerating
growth in the economy, common stocks historically have conserved their value
better than bonds in part due to a rise in interest rates that occur
coincidentally with accelerating growth and profitability of the companies.
 
RISK FACTORS
- -------------------------------------------------------------------
 
The following discussion relates to all three 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 stocks 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.
 
STOCK INVESTMENT RISKS. Because each fund invests a substantial portion of its
assets in stocks, 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. Stock 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
 
                                       24
<PAGE>
company also affect that company's stock price (for example, poor earnings, loss
of major customers, or major litigation). The funds cannot always predict the
factors that will affect a stock'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
any one company and by not holding a substantial amount of the stock of any one
company.
 
For the Growth Fund and the Equity Income Fund, the portfolio managers decide to
overweight or underweight certain industry sectors and to purchase individual
stocks based on their assessment of the future growth or income prospects of an
industry sector or particular stock. If certain industries or investments do not
perform as a fund expects (I.E., do not grow in value or produce dividend income
as expected), that fund could underperform its peers or lose money.
 
The Growth Fund is generally considered more aggressive than the Equity Income
and Balanced Funds because it invests for capital appreciation in common stocks,
emphasizing "growth" stocks that tend to be more volatile than other
investments. Investors in the Growth Fund should expect greater fluctuations in
share price, yield, and total return than with less aggressive funds.
 
DEBT SECURITIES RISKS. Debt securities are subject to changes in their values
due to changes in prevailing interest rates. 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. 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. The magnitude of these fluctuations will often be greater for longer-term
debt securities than shorter-term debt securities.
 
The funds could lose money if any bonds they own are downgraded in credit rating
or go into default. In general, lower-rated bonds, such as junk bonds, have
higher credit risks. The Growth Fund is the only fund permitted to invest in
junk bonds. Junk bonds have additional risks, including limitations on a fund's
ability to re-sell the
 
                                       25
<PAGE>
lower-rated debt securities and less readily available market quotations for
such securities. If there are not readily available market quotations for a debt
security, its value is determined largely by the investment manager's judgment.
When and if the debt security is sold, the investment manager may find that its
estimation of the debt security's value is substantially different than the
actual price at which it can be sold. Moreover, substantial redemptions of fund
shares could require a fund to sell portfolio securities at a time when a sale
might not be favorable.
 
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.
 
SMALLER COMPANY RISKS. Smaller companies in which each of the funds may invest
may involve greater risks than large established companies. Such smaller
companies may have limited product lines, markets, financial resources, and
management depth. Their securities may trade less frequently and in more limited
volume than the securities of larger or more established companies. Smaller
companies may also be more vulnerable than larger companies to adverse business
or market developments. As a result, the prices of smaller companies may
fluctuate to a greater degree than the prices of securities of larger companies.
 
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
 
                                       26
<PAGE>
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. 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"). You should carefully review
all account statements 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.
    P.O. Box 58969
    Houston, Texas 77258-8969
 
Certificates are not issued for shares of the funds. 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.
 
Investors whose shares are held in the name of a broker-dealer or other party
are not shareholders of record and, therefore, may not be able to utilize
services available only to shareholders of record.
 
OPENING AN ACCOUNT: To purchase shares, you must submit a completed account
application which includes the purchaser suitability form. The application and
suitability form are to be mailed directly to SM&R at the above address. If you

<PAGE>
certain systematic investment programs (See "Special Purchase Plans and

the right to reject any purchase.

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 day the New York Stock Exchange (the "Exchange") is open for regular
trading. The offering price equals a fund's net asset value plus the sales
charge, if any. (See "Shares of the Funds-- Class T Sales Charges.")
 
EFFECTIVE DATE OF PURCHASES AND REDEMPTIONS (WHEN SHARES ARE PRICED). We
calculate net asset value once each day the Exchange is open at the close of
regular trading on the Exchange (currently 3:00 p.m.
 
                                       28
<PAGE>
Central Time). In the event the Exchange closes early on a particular day, we
will determine the net asset value of each fund as of the close of the Exchange
that day. 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 day the Exchange
is open for regular trading, we will execute purchases and redemptions at the
next 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, or on any day that the
Exchange is closed, 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.
 
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 funds offers other services
and plans designed to facilitate investments. At this time, there is no charge
to you for these services. The funds 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, broker-dealer 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
 
                                       29
<PAGE>
loan, or credit union account using the Automated Clearing House ("ACH")
network. To arrange for electronic transfers, complete the relevant Special
Investor Services 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 only use telephone services for transaction amounts
of $500 or more. You can take advantage of this service by completing the
appropriate Special Investor Services sections of the account application when
opening your account. Through this service, you will be able to purchase
additional shares for an existing SM&R mutual fund account by ACH. You may also
use the telephone services to 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 or SM&R 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;
 
                                       30
<PAGE>
    (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).
 
During times of economic turmoil or market volatility or as a result of severe
weather or a natural disaster, it may be difficult to contact SM&R by telephone
to institute a redemption or exchange.
 
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.
 
EXCHANGE PRIVILEGE. As an investor in a fund, you may be permitted to exchange
shares that you own in a fund with shares of some of the other mutual funds
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 OR WHETHER AN EXCHANGE IS PERMITTED.
 
WE MAY TERMINATE OR CHANGE THE TERMS OF ANY EXCHANGE OFFER AT ANY TIME.
 
You may exchange Class T shares of a fund, without an exchange fee or sales
charge, for Class T shares of another fund managed by SM&R. You also may
exchange your Class T shares for shares of SM&R Investments, Inc.'s Primary Fund
and Money Market Fund, provided that you meet any minimum investment requirement
for the shares you wish to acquire.
 
                                       31
<PAGE>
We waive any sales charges on Class A and Class T shares acquired through an
exchange if you previously paid a sales charge on amounts invested in those
shares. For example, you purchase Class T shares of the Growth Fund. You then
exchange your Class T shares for shares of the SM&R Investments, Inc. Money
Market Fund. Later, you re-exchange those shares of the Money Market Fund for
the Class T shares of the Equity Income Fund. We would not impose any sales
charge upon re-exchange into Class T shares because you previously paid a sales
charge on those amounts invested in shares. In other words, we will never impose
a front-end sales charge on the same investment twice.
 
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 that are registered in the
        same name, address and, if applicable, taxpayer identification number;
 
    (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 a written exchange must meet the minimum investment
        requirement applicable to the shares of the fund that you would acquire
        through the exchange;
 
    (d) the minimum dollar amount of a telephone exchange is $500;
 
    (e) SM&R must have received full payment for the shares being exchanged;
 
                                       32
<PAGE>
    (f) 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);
 
    (g) any shares that you wish to exchange must have been held for at least
        ten (10) business days;
 
    (h) certificates representing shares, if any, are returned before such
        shares are exchanged; and
 
    (i)  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 funds and raise the funds' 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 invest in with shares of the funds:
 
      - Individual Retirement Accounts (IRAs), which include traditional IRAs,
        Roth IRAs, Education IRAs, and SIMPLE IRAs,
 
                                       33
<PAGE>
      - 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 funds. 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 funds and will be automatically deducted
from each account. An individual considering a retirement plan may wish to
consult with an attorney or tax adviser.
 
DIVIDENDS, DISTRIBUTIONS, AND TAXES
 
DIVIDENDS. The Equity Income and Balanced Funds will pay dividends from
investment income, if any, quarterly, generally during the months of March,
June, September and December, and distribute capital gains, if any, in December.
The Growth Fund will pay dividends from investment income, if any, semi-annually
during the months of June and December and distribute capital gains, if any, in
December. Dividends from net investment income may include net short-term
capital gains, if any.
 
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.
 
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
 
                                       34
<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
funds. 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 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.
Corporations may be entitled to take a dividends-received deduction for a
portion of certain dividends they receive. 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.
 
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 funds 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.
 
                                       35
<PAGE>
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., P.O. Box 58969, Houston,
Texas 77258-8969.
 
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. Telephone
privileges are not available to shareholders automatically. 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 proceeds of the redemption are $500 or more and do not exceed
        $25,000; and
 
    (e) the security procedures discussed under "Special Purchase Plans And
        Services--Exchange Privilege" have been met.
 
These instructions may be changed only in writing, accompanied by a signature
guarantee and additional documentation may be required for corporations.
 
                                       36
<PAGE>
FAX REDEMPTIONS. You may request redemptions by fax as long as they meet the
requirements stated in (a)-(d) under Telephone Redemptions above.
 
SYSTEMATIC WITHDRAWAL PLAN. Each fund 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 funds 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. 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 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.
 
                                       37
<PAGE>
"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 SM&R 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 fund 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 fund 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
 
                                       38
<PAGE>
exchange, or registered securities association. WITNESSING OR NOTARIZATION IS
NOT SUFFICIENT.
 
TEXAS OPTIONAL RETIREMENT PROGRAM. You may not redeem shares 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.
 
REDEMPTION OF SMALL ACCOUNTS. The funds reserve 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 $500. You will be notified
that the value of your account is less than the required minimum and allowed at
least 60 days to make an additional investment to increase the value of your
account above the required minimum. The funds may, from time to time, change
such required minimum investment.
 
RIGHTS RESERVED BY THE FUNDS. The funds, acting directly or through SM&R,
reserve 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 or has
        occurred;
 
      - 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;
 
                                       39
<PAGE>
      - to refuse to act on instructions not believed to be genuine; or
 
      - to eliminate duplicate mailings of fund material to shareholders who
        reside at the same address.
 
THE FUNDS AND MANAGEMENT
- -------------------------------------------------------------------
 
INVESTMENT ADVISER
 
Each fund's Board of Directors has delegated to Securities Management and
Research, Inc. ("SM&R"), the fund's investment adviser, the management of the
fund's 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. While the use of this
combined Prospectus subjects each fund to possible liability as the result of
statements or omissions regarding another fund, the Board of Directors of each
fund considers the benefits to the respective fund of using a combined
Prospectus to outweigh the risk.
 
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 banks, employee benefit plans, other
investment companies, banks, foundations and endowment funds.
 
ADVISORY AGREEMENTS
 
GROWTH FUND. We deduct an investment advisory fee from the value of the shares
each day. We calculate this fee for the Growth Fund at the annual rate as
follows:
 
<TABLE>

            ON THE PORTION OF THE FUND'S               BASIC ADVISORY

<S>                                                   <C>
Not exceeding $100,000,000                                   0.750%
Exceeding $100,000,000 but not exceeding
  $200,000,000                                               0.625%
Exceeding $200,000,000 but not exceeding
  $300,000,000                                               0.500%
Exceeding $300,000,000                                       0.400%
</TABLE>
 
We adjust the basic advisory fee rate by comparing the fund's investment
performance during the previous thirty-six (36) months with the
 
                                       40
<PAGE>
investment performance of the Lipper Growth Fund Index (the "Lipper Index")
published by Lipper Analytical Services, Inc. over the same period.
Specifically, we adjust the basic advisory fee each month by adding to or
subtracting from such rate, when appropriate, the applicable performance
adjustment amount percentage shown in the table below. The resulting advisory
fee rate is then applied to the average daily net asset value of the fund for
the succeeding month. The advisory fee for such month will be one-twelfth (1/12)
of the resulting dollar figure.

SM&R received total advisory fees from the Growth, Equity Income, and Balanced
Funds for the fiscal year ended December 31, 1997 of 0.60%, 0.69%, and 0.75%,
respectively, of each fund's average daily net assets. Each fund's advisory fees
may be higher than the fees paid by other mutual funds, but each fund believes
its fees are comparable to those paid by funds with the same or similar
investment objective.
 
ADMINISTRATIVE SERVICES
 
Pursuant to Administrative Service Agreements with the funds, SM&R provides all
non-investment related management, executive, administrative, transfer agent,
and operational services to the Funds. Under the agreements, SM&R receives an
administrative service fee from each fund at the annual rate of average daily
net asset values as follows:

In each fund's administrative service agreement, SM&R has agreed to pay (or to
reimburse each fund for) each fund's regular operating expenses in excess of
1.25% 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.

- --------------------------------------------------------------------------
 
The following financial highlights table is intended to help you understand the
Growth 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 Growth 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 Growth Fund, which for the year ended through December 31, 1997 have been
audited by Tait, Weller & Baker, independent auditors, whose report, along with
the Growth Fund's financial statements, are incorporated by reference into the
Statement of Additional Information, which is available upon request. The
information for years ending December 31, 1996 and prior, has been audited by
the Growth Fund's former independent auditors. The information for the six month
period ended June 30, 1998 was derived from unaudited financial statements of
the Growth Fund.

(Description of Ratings Used in Prospectus)
- -------------------------------------------------------------------
 
BOND RATINGS
 
DESCRIPTION OF STANDARD & POOR'S CORPORATION'S LONG-TERM BOND (BONDS THAT EXTEND
LONGER THAN ONE YEAR) 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 impair the obligor's capacity or
      willingness to meet its financial commitment on the obligation.
 
DESCRIPTION OF MOODY'S INVESTOR'S SERVICE, INC.'S LONG-TERM BOND (BONDS THAT
EXTEND LONGER THAN ONE YEAR) 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-
 
                                      A-1
<PAGE>
      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 larger than the 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.
 
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.
 
PREFERRED STOCK RATING
 
DESCRIPTION OF STANDARD & POOR'S CORPORATION'S PREFERRED STOCK RATING:
 
AAA  This is the highest rating that may be assigned by Standard & Poor's to a
      preferred stock issue and indicates an extremely strong capacity to pay
      the preferred stock obligations.
 
AA   A preferred stock issue rate "AA" also qualifies as a high-quality, fixed-
      income security. The capacity to pay preferred stock obligations is very
      strong, although not as overwhelming as for issues rated "AAA."
 
A    An issue rated "A" is backed by a sound capacity to pay the preferred stock
      obligations, although it is somewhat more susceptible to the adverse
      effects of changes in circumstances and economic conditions.
 
                                      A-2
<PAGE>
BBB  An issue rated "BBB" is regarded as backed by an adequate capacity to pay
      the preferred stock obligations. Whereas it normally exhibits adequate
      protection parameters, adverse economic conditions or changing
      circumstances are more likely to lead to a weakened capacity to make
      payments for a preferred stock in this category than for issues in the "A"
      category.
 
BB   Preferred stock rated "BB," "B," and "CCC" are regarded, on balance, as
B     predominantly speculative with respect to the issuer's capacity to pay
CCC  preferred stock obligations. "BB" indicates the lowest degree of
      speculation and "CCC" the highest. While such issues will likely have some
      quality and protective characteristics, these are outweighed by large
      uncertainties or major risk exposures to adverse conditions.
 
DESCRIPTION OF MOODY'S INVESTORS SERVICE, INC.'S PREFERRED STOCK RATING:
 
aaa   An issue which is rated "aaa" is considered to be a top-quality preferred
      stock. This rating indicates good asset protection and the least risk of
      dividend impairment within the universe of preferred stocks.
 
aa    An issue which is rated "aa" is considered a high-grade preferred stock.
      This rating indicates that there is a reasonable assurance the earnings
      and asset protection will remain relatively well maintained in the
      foreseeable future.
 
a     An issue which is rated "a" is considered to be an upper-medium grade
      preferred stock. While risks are judged to be somewhat greater than in the
      "aaa" and "aa" classification, earnings and asset protection are,
      nevertheless, expected to be maintained at adequate levels.
 
baa   An issue which is rated "baa" is considered to be a medium-grade preferred
      stock, neither highly protected nor poorly secured. Earnings and asset
      protection appear adequate at present but may be questionable over any
      great length of time.
 
ba    An issue is rated "ba" considered to have speculative elements and its
      future cannot be considered well assured. Earnings and asset protection
      may be very moderate and not well safeguarded during adverse periods.
      Uncertainty of position characterizes preferred stocks in this class.
 
b     An issue which is rated "b" generally lacks the characteristics of a
      desirable investment. Assurance of dividend payments and maintenance of
      other terms of the issue over any long period of time may be small.
 
FEDERAL FUNDS

Information, "Federal Funds" means a commercial bank's deposits in a Federal
Reserve Bank which can be transferred from one member bank's account to that of
another member bank on the same day. Federal Funds are considered to be

GROWTH FUND'S INVESTMENT OBJECTIVE
                   The Growth Fund seeks long-term capital
                   growth by investing primarily in common stocks that provide
                   an opportunity for capital appreciation over time. Growth
                   Fund's principal investment strategies
 
GROWTH FUND'S PRINCIPAL INVESTMENT STRATEGY
 
                   The Growth Fund normally invests at least 85% of its total
                   assets in common stocks. In selecting stocks, this fund:
                   - chooses the stocks of financially sound companies that have
                     a proven ability to make and sustain a profit over time,
                     and
                   - places an emphasis on companies with growth potential.
 
                   The Growth Fund generally purchases a higher proportion of
                   stocks (relative to their market weight) from those sectors
                   of the market with higher growth prospects, referred to as
                   "overweighting." Examples of sectors with higher growth
                   prospects currently include technology, healthcare, and
                   consumer staples. On the other hand, the fund generally
                   purchases a smaller proportion of stocks (relative to their
                   market weight) from sectors of the market with below average
                   growth characteristics (for example, utilities, basic
                   materials, and communications services), referred to as
                   "underweighting."
 
                   The Growth Fund may also invest in debt obligations (such as
                   convertible preferred stocks, debentures, and notes),
                   including below investment grade bonds ("junk" bonds).

PRINCIPAL RISKS OF INVESTING IN THE GROWTH FUND
                   You could lose money on your investment in the
                   Growth Fund, or it could underperform other investments, if
                   any of the following occurs:
                   - the stock market goes down
                   - the investment decisions of management (such as sector
                     overweighting and underweighting and individual stock
                     selection) do not achieve the desired results
                   - interest rates increase
                   - issuers of debt obligations default or are unable to pay
                     amounts due
 
                   Investments by the Growth Fund in smaller companies may
                   involve greater risks than larger established companies.

                   - are investing for retirement or other goals that are many
                     years in the future

EQUITY INCOME FUND'S INVESTMENT OBJECTIVE
                   The Equity Income Fund seeks current income
                   with a secondary objective of long-term capital appreciation.
 
EQUITY INCOME FUND'S PRINCIPAL INVESTMENT STRATEGIES
                   The Equity Income Fund normally invests at
                   least 75% of its assets in equity securities. This fund also
                   invests in preferred stocks and investment grade debt
                   securities (such as publicly traded corporate bonds,
                   debentures, notes, commercial paper, repurchase agreements,
                   and certificates of deposit). In selecting common and
                   preferred stocks, the fund focuses on companies with
                   consistent and increasing dividend payment histories and
                   future earnings potential sufficient to continue such
                   dividend payments. This fund's goal is to maintain a
                   portfolio dividend yield (before fees and expenses) at least
                   50% greater than that of the S&P 500 Index.
 
                   The Equity Income Fund generally purchases a higher
                   proportion of stocks (relative to their market weight) from
                   those sectors of the market with greater dividend prospects,
                   referred to as "overweighting." Examples of sectors with
                   greater dividend prospects currently include financial
                   companies like banks, insurance companies, and real estate
                   investment trusts. On the other hand, the fund generally
                   purchases a smaller proportion of stocks (relative to their
                   market weight) from sectors of the market with below average
                   dividend yields (such as technology and consumer staples),
                   referred to as "underweighting."

                   investments, if any of the following occurs:
                   - the stock market goes down and/or interest rates increase

                   Investments by the Equity Income Fund in smaller companies
                   may involve greater risks than larger established companies.
 
WHO MAY WANT TO INVEST IN THE EQUITY INCOME FUND
                   This fund may be appropriate if you:
                   - are looking for a fund that has both growth and income
                     components
                   - are seeking to protect the purchasing power of your money
                     while retaining the potential for growth and reducing
                     exposure to the volatility of the market
                   - are willing to accept higher short-term risk along with
                     higher potential long-term returns
                   - are retired or nearing retirement
 
                   This fund may NOT be appropriate if you:
                   - are investing for maximum return over a long time horizon
                   - require a high degree of stability of your principal
                   - desire your return to be either ordinary income or capital
                     gains, but not both

RISK/RETURN SUMMARY                                     SM&R BALANCED FUND, INC.
- -------------------------------------------------------------------
 
BALANCED FUND'S INVESTMENT OBJECTIVE
                   The Balanced Fund seeks to conserve principal, produce
                   current income, and achieve long-term capital appreciation.
 
BALANCED FUND'S PRINCIPAL INVESTMENT STRATEGIES
                   The Balanced Fund uses a "balanced" approach
                   by investing part of the assets in common stocks and the
                   remainder in a combination of high-grade bonds, convertible
                   bonds, and money market instruments. The ratio of stocks to
                   bonds changes in response to changing economic conditions.
                   This flexibility may help to reduce price volatility.
 
                   This fund's goal is relative stability of principal through a
                   balance of stocks, bonds, and cash. The stocks are
                   diversified and are selected based upon two models. One model
                   is based on profitability measurements and the other model is
                   based on the corporation's return on invested cash. The
                   bonds, meanwhile, may serve as a stabilizing force during
                   times of eroding stock market value, as well as provide a
                   fixed income payment stream. The fund invests at least 25% of
                   assets in fixed income securities, all of which are rated BBB
                   or better (investment grade). Common stocks purchased by the
                   fund will have a market capitalization of at least $100
                   million and be listed on a national exchange.
 
PRINCIPAL RISKS OF INVESTING IN THE BALANCED FUND
                   You could lose money on your investment in the
                   Balanced Fund, or it could underperform other investments, if
                   any of the following occurs:
                   - interest rates increase or the stock market goes down
                   - issuers of debt obligations default or are unable to pay
                     amounts due
                   - the investment decisions of management do not achieve the
                     desired results
 
                   Investments by the Balanced Fund in smaller companies may
                   involve greater risks than larger established companies.

RISK/RETURN SUMMARY
- -------------------------------------------------------------------
 
TYPES OF INVESTMENT RISK
 
As indicated above, each of the three funds is subject to the following types of
risks to varying degrees:
 
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. THIS RISK APPLIES TO
ALL OF THE FUNDS, BUT MAY HAVE A GREATER IMPACT ON THE BALANCED AND EQUITY
INCOME FUNDS.
 
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. THIS RISK APPLIES TO ALL OF THE FUNDS, BUT MAY HAVE A GREATER IMPACT ON
THE BALANCED AND EQUITY INCOME FUNDS.
 
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.

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 over a ten year period, and
- - by showing how each fund's average annual returns for 1, 5, and 10 years
  compare to those of both a broad-based securities market index, and an index
  of funds with similar investment objectives.
 
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. No sales loads apply to Class Y
shares. We created the multiple classes of shares on January 1, 1999.
 
Past performance is not necessarily an indication of how the funds will perform
in the future.

NOTES TO FEES AND EXPENSES OF THE FUNDS
 
(1) The "Management Fees" and "Other Expenses" shown below for the funds are for
    the year ended December 31, 1997. NO DISTRIBUTION OR SERVICE (12b-1) FEES
    ARE IMPOSED ON CLASS Y SHARES OF THE FUNDS.
 
(2) "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 Growth, Equity Income, and Balanced Fund for the fiscal year
    ended December 31, 1997.
 
(3) 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% 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. During the fiscal year ended December 31, 1997, SM&R waived
    management fees of 0.10% for the Balanced Fund.

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 Class Y shares of fund 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:

SM&R. These financial intermediaries may include broker-dealers and investment
advisers and may charge you separately for their services.
 
Class Y shares of the funds are offered to institutions and certain other
investors at net asset value, with no sales charges or distribution and service
(12b-1) fees. As a result, 100% of your purchase is immediately invested.
 
Class Y shares may be purchased by:
 
    (a) institutional investors, such as insurance companies, banks, investment
        companies, retirement plans, and other institutional investors approved
        by SM&R;
 
    (b) trust companies and bank trust departments for funds over which they
        exercise exclusive discretionary investment authority or they serve as a
        directed trustee and which are held in a fiduciary, agency, advisory,

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. More investment information is in the Statement of Additional
Information. 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.
 
SM&R GROWTH FUND, INC.
(FORMERLY NAMED AMERICAN NATIONAL GROWTH FUND, INC.)
 
The Growth Fund considers its portfolio investments and the composition of its
total portfolio from the viewpoint of potential capital appreciation. The Growth
Fund adjusts this composition from time to time in light of current conditions.
Under normal conditions, the Growth Fund invests at least 85% of its total
assets in common stocks.
 
The Growth Fund invests in the stocks of financially sound companies that have a
proven ability to make and sustain a profit over time. Management places an
emphasis on companies with growth potential. The Growth Fund does not employ
exotic investment strategies, such as using options and futures.
 
We identify candidate stock investments based on (1) low equity valuation
(price) and (2) improving earnings. Then, we evaluate each candidate stock on a
fundamental basis by examining past financial performance, managerial skill and
foresight, and relative valuation to industry peers and the market as a whole.
We utilize this combination of disciplines and human judgement to drive our
stock selection process. We believe in evaluating each company's prospects as
 
                                       15
<PAGE>
opposed to relying on broad forecasts of industry prospects. We do not attempt
to time economic, market, style or capitalization cycles. Diversification, or
weighting of individual economic sectors, is also dictated by a combination of
disciplines and human judgement to varying degrees. We believe in never having
less than half or more than double the market weighting in any one sector. The
Growth Fund limits cash to 15% of its assets unless circumstances dictate
otherwise.
 
Because of the Growth Fund's goal of seeking long-term capital growth, certain
sectors of the market will have greater weight in the Growth Fund's portfolio
while other sectors of the market will have lower representation. For example,
the Growth Fund generally overweights the technology sector, which represents
approximately 15% of the Standard & Poor's 500 Index, in the portfolio relative
to its market weight. This overweighting reflects the higher growth prospects of
technology companies relative to the average company in the market. At varying
times, we may also overweight other sectors of the market providing above
average growth prospects, like healthcare and consumer staples.
 
Conversely, the Growth Fund generally underrepresents certain sectors of the
market in its portfolio that tend to have below average growth characteristics,
like utilities, basic materials, and communications services. As a result of
such strategic overweighting and underweighting, the Growth Fund's performance
may differ substantially from broad market indexes like the S&P 500 and tend to
incur more price volatility than these indexes.
 
The Growth Fund may invest in convertible preferred stocks rated at least "B" by
Standard and Poor's Corporation ("S&P") or at least "b" by Moody's Investors
Service, Inc. ("Moody's") preferred stock ratings, and convertible debentures
and notes rated at least "B" by S&P and Moody's corporate bond ratings.
Investments in convertible securities having these ratings may involve greater
risks than convertible securities having higher ratings.
 
The proportion of assets invested in any particular type of security can be
expected to vary, depending on SM&R's appraisal of market and economic
conditions. Common stocks and convertible securities purchased will be of
companies that SM&R believes will provide an opportunity for capital
appreciation. On a temporary basis, the Growth Fund may invest in commercial
paper which at the date of
 
                                       16
<PAGE>
such investment, is rated in one of the two top categories by one or more of the
nationally recognized statistical rating organizations, in certificates of
deposit in domestic banks and savings institutions having at least $1 billion of
total assets, and in repurchase agreements.
 
SM&R EQUITY INCOME FUND, INC.
(FORMERLY NAMED AMERICAN NATIONAL INCOME FUND, INC.)
 
The Equity Income Fund considers its portfolio investments and the composition
of its total portfolio not only from the viewpoint of present and potential
yield, but also from the viewpoint of potential capital appreciation. We adjust
this composition of portfolio investments from time to time to best accomplish
the Equity Income Fund's investment objectives under current conditions.
 
In pursuit of its objectives, the Equity Income Fund will invest in common
stocks, preferred stocks, and marketable debt securities selected in accordance
with its investment objectives. Common and preferred stocks purchased will
generally be of companies with consistent and increasing dividend payment
histories that SM&R believes will have further earnings potential sufficient to
continue such dividend payments. Debt securities include publicly traded
corporate bonds, debentures, notes, commercial paper, repurchase agreements, and
certificates of deposit in domestic banks and savings institutions having at
least $1 billion of total assets. The proportion of assets invested in any
particular type of security can be expected to vary, depending on SM&R's
appraisal of market and economic conditions. Under normal conditions, the Equity
Income Fund will invest at least 75% of its assets in equity securities rather
than debt securities.
 
We view common stocks, as well as investments in preferred stocks and bonds
convertible into common stock, from their potential for capital appreciation in
addition to their current and potential income yield. Our goal is to maintain a
portfolio dividend yield (before fees and expenses) at least 50% greater than
that of the S&P 500 Index.
 
We identify candidate stock investments based on (1) low equity valuation
(price) and (2) improving earnings. Then, we evaluate each candidate stock on a
fundamental basis by examining past financial performance, managerial skill and
foresight, and relative valuation to industry peers and the market as a whole.
We utilize this combination of disciplines and human judgement to drive our
stock selection
 
                                       17
<PAGE>
process. We believe in evaluating each company's prospects as opposed to relying
on broad forecasts of industry prospects. We do not attempt to time economic,
market, style or capitalization cycles. Diversification, or weighting of
individual sectors, is also dictated by a combination of disciplines and human
judgement to varying degrees. We believe in never having less than half or more
than double the market weighting in any one sector. Cash is limited to 15% of
the fund unless circumstances dictate otherwise.
 
Certain sectors of the market will have greater weight in the Equity Income
Fund's portfolio while other sectors of the market will have lower
representation. For example, the Equity Income Fund generally overweights the
finance sector in its portfolio relative to that sector's market weight (which
is approximately 16% of the Standard & Poor's 500 Index). This reflects the
greater dividend prospects of financial companies like banks, insurance
companies, and real estate investment trusts as compared to the average company
in the market. At varying times, we may also overweight other sectors of the
market that provide above average dividend prospects, like utilities and energy.
 
Conversely, the Equity Income Fund generally underrepresents certain sectors of
the market tending to have below average dividend yields, like technology,
consumer staples, and healthcare. As a result of such strategic overweighting
and underweighting, the Equity Income Fund's performance may differ
substantially from broad market indexes like the S&P 500.
 
Corporate debt obligations purchased by the Equity Income Fund will consist only
of obligations rated either Baa or better by Moody's or BBB or better by S&P.
Bonds which are rated Baa by Moody's are considered as medium grade obligations,
that is, they are neither highly protected nor poorly secured. Bonds rated BBB
by S&P are regarded as having an adequate capacity to pay interest and repay
principal. Commercial paper and notes will consist only of direct obligations of
corporations whose bonds and/or debentures are rated as set forth above.
 
SM&R BALANCED FUND, INC.
(FORMERLY NAMED TRIFLEX FUND, INC.)
 
The Balanced Fund uses a "balanced" approach by investing part of its assets in
stocks of well-known companies and the remainder in a combination of high-grade
bonds, bonds convertible into the common
 
                                       18
<PAGE>
stock of the issuing corporations, and money market instruments. We change the
ratio of stocks to bonds in response to changing economic conditions. This
flexibility helps to reduce price volatility.
 
The Balanced Fund's goal is relative stability of principal through a balance of
stocks, bonds, and cash. The stocks serve to capture the benefits that ownership
in corporate America brings. The bonds, meanwhile, can serve as a stabilizing
force during times of eroding stock market value, as well as provide a fixed
income payment stream into the portfolio.
 
The Balanced Fund will only purchase common stocks and convertible securities of
corporations having a market capitalization of at least $100 million, an
operating history of at least three (3) years, and a listing on the New York
Stock Exchange, American Stock Exchange, or Over-The-Counter markets. The
Balanced Fund will only purchase corporate bonds rated either Baa or better by
Moody's or BBB or better by S&P. Bonds which are rated Baa by Moody's are
considered as medium grade obligations, that is, they are neither highly
protected nor poorly secured. Bonds rated BBB by S&P are regarded as having an
adequate capacity to pay interest and repay principal. Commercial paper and
notes will consist only of direct obligations of corporations whose bonds and/or
debentures are rated as set forth above. The Balanced Fund may also invest in
repurchase agreements. This balanced investment policy is intended to reduce
risk and to obtain results in keeping with the Balanced Fund's objectives.
 
The Balanced Fund will invest in fixed-income securities and equity securities
as described above. However, the Balanced Fund will sometimes be more heavily
invested in equity securities and at other times it will be more heavily
invested in fixed-income securities, depending on management's appraisal of
market and economic conditions. SM&R believes that a fund that is wholly
invested in fixed-income securities carries a large interest rate risk. Interest
rate risk is the uncertainty about losses due to changes in the rate of interest
on debt instruments. The major interest rate risk for investors, however, is not
in the interest rate itself, but in the change in the market price of bonds that
results from changes in the prevailing interest rate. Higher interest rates
would mean lower bond prices and lower net asset value for the Balanced Fund's
shareholders assuming no change in its current investment objective and
portfolio. Diversifying the Balanced Fund's portfolio with investments such as
 
                                       19
<PAGE>
commercial paper, convertible securities, and common stocks may reduce the
decline in value attributable to the increase in interest rate and resulting
decrease in the market value of bonds and may reduce the interest rate risk.
However, stock prices also fluctuate in response to a number of factors,
including changes in general level of interest rates, economic and political
developments, and other factors which impact individual companies or specific
types of companies. Such market risks cannot be avoided but can be limited
through a program of diversification and a careful and consistent evaluation of
trends in the capital market and fundamental analysis of individual equity
holdings.
 
The Balanced Fund's goal of preservation of capital while owning common stocks
depends on various factors, including the sustained long-term growth of the
United States economy. SM&R recognizes that recessions occur but also recognizes
that the economy historically has come back from those recessions. Therefore,
SM&R believes that the United States economy will continue to grow, that the
political environment will continue to be relatively stable, and that the
financial markets will continue to function in a reasonably orderly fashion. As
long as these factors occur, SM&R believes that there is a reasonable likelihood
the Balanced Fund can reach its goal of preservation of capital while at the
same time investing in common stock.
 
SM&R, through an ongoing program of asset allocation, will determine the
appropriate level of equity holding consistent with SM&R's outlook and
evaluation of trends in the economy and the financial markets. The Balanced Fund
determines its level of commitment to common stocks and specific common stock
investments as a result of this process. For example, within an environment of
rising inflation, common stocks historically have preserved their value better
than bonds; therefore, inclusion of common stocks could tend to conserve
principal better than a portfolio consisting entirely of bonds and other debt
obligations. In addition, within an environment of accelerating growth in the
economy, common stocks historically have conserved their value better than bonds
in part due to a rise in interest rates that occur coincidentally with
accelerating growth and profitability of the companies.

RISK FACTORS
- -------------------------------------------------------------------
 
The following discussion relates to all three 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 stocks 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.
 
STOCK INVESTMENT RISKS. Because each fund invests a substantial portion of its
assets in stocks, 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. Stock 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 that company's stock price (for example, poor earnings, loss of major
customers, or major litigation). The funds cannot always predict the factors
that will affect a stock'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 any one company
and
 
                                       21
<PAGE>
by not holding a substantial amount of the stock of any one company.
 
For the Growth Fund and the Equity Income Fund, the portfolio managers decide to
overweight or underweight certain industry sectors and to purchase individual
stocks based on their assessment of the future growth or income prospects of an
industry sector or particular stock. If certain industries or investments do not
perform as a fund expects (I.E., do not grow in value or produce dividend income
as expected), that fund could underperform its peers or lose money.
 
The Growth Fund is generally considered more aggressive than the Equity Income
and Balanced Funds because it invests for capital appreciation in common stocks,
emphasizing "growth" stocks that tend to be more volatile than other
investments. Investors in the Growth Fund should expect greater fluctuations in
share price, yield, and total return than with less aggressive funds.
 
DEBT SECURITIES RISKS. Debt securities are subject to changes in their values
due to changes in prevailing interest rates. 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. 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. The magnitude of these fluctuations will often be greater for longer-term
debt securities than shorter-term debt securities.
 
The funds could lose money if any bonds they own are downgraded in credit rating
or go into default. In general, lower-rated bonds, such as junk bonds, have
higher credit risks. The Growth Fund is the only fund permitted to invest in
junk bonds. Junk bonds have additional risks, including limitations on a fund's
ability to re-sell the lower-rated debt securities and less readily available
market quotations for such securities. If there are not readily available market
quotations for a debt security, its value is determined largely by the
investment manager's judgment. When and if the debt security is sold, the
investment manager may find that its estimation of the debt security's value is
substantially different than the actual price at which it can be sold. Moreover,
substantial redemptions of fund shares could require a fund to sell portfolio
securities at a time when a sale might not be favorable.
 
                                       22
<PAGE>
SMALLER COMPANY RISKS. Smaller companies in which each of the funds may invest
may involve greater risks than large established companies. Such smaller
companies may have limited product lines, markets, financial resources, and
management depth. Their securities may trade less frequently and in more limited
volume than the securities of larger or more established companies. Smaller
companies may also be more vulnerable than larger companies to adverse business
or market developments. As a result, the prices of smaller companies may
fluctuate to a greater degree than the prices of securities of larger companies.
 
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 directly from SM&R or through broker-dealers
and investment advisers who have executed a distribution or sales agreement with
SM&R. Such purchases will be at the
 
                                       23
<PAGE>
offering price for such shares determined as and when provided below (See
"Pricing of Fund Shares"). You should carefully review all account statements
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.
    P.O. Box 58969
    Houston, Texas 77258-8969
 
Certificates are not issued for shares of the funds. 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.
 
Investors whose shares are held in the name of a broker-dealer or other party
are not shareholders of record and therefore may not be able to utilize services
available only to shareholders of record.
 
OPENING AN ACCOUNT: To purchase shares, you must submit a completed account
application. If you would like to take advantage of the electronic services
available, please complete the applicable Special Investor Services 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, the minimum initial investment
is $500,000 (we may waive this minimum for certain institutional investors). All
subsequent investments must be at least $2,000. We apply investment minimums to
the aggregate value invested in omnibus accounts established by broker-dealers.
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.
 
                                       24
<PAGE>
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 Y of the Growth Fund)
    Fund Account Number (number appears on your 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 day the New York Stock Exchange (the "Exchange") is open for regular
trading. You may purchase Class Y shares without a sales charge. Accordingly,
the offering price for Class Y shares of a fund is the net asset value per
share.
 
EFFECTIVE DATE OF PURCHASES AND REDEMPTIONS (WHEN SHARES ARE PRICED). We
calculate net asset value once each day the Exchange is open at the close of
regular trading on the Exchange (currently 3:00 p.m. Central Time). In the event
the Exchange closes early on a particular day, we will determine the net asset
value of each fund as of the close of the Exchange that day. 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 day the Exchange is open for regular
trading, we will execute purchases and redemptions at the next applicable price
determined that day if:
 
      - SM&R receives your order in proper form prior to the close of the
        Exchange;
 
                                       25
<PAGE>
      - 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 or on any day that the
Exchange is closed, 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.
 
SPECIAL PURCHASE PLANS AND SERVICES
 
The funds offer services and plans designed to facilitate investments. At this
time, there is no charge to you for these services. The funds 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 broker-dealer, investment adviser 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 Special Investor Services 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
 
                                       26
<PAGE>
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 only use telephone services for transaction amounts
of $500 or more. You can take advantage of this service by completing the
appropriate Special Investor Services sections of the account application when
opening your account. Through this service, you will be able to purchase
additional shares for an existing SM&R mutual fund account by ACH. You may also
use the telephone services to 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 broker-dealer, investment adviser or SM&R
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).
 
                                       27
<PAGE>
During times of economic turmoil or market volatility or as a result of severe
weather or a natural disaster, it may be difficult to contact SM&R by telephone
to institute a redemption or exchange.
 
EXCHANGE PRIVILEGE. As an investor in a fund, you may be permitted to exchange
shares that you own in a fund with shares of some of the other mutual funds
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 AND WHETHER AN EXCHANGE IS PERMITTED.
 
WE MAY TERMINATE OR CHANGE THE TERMS OF ANY EXCHANGE OFFER AT ANY TIME.
 
You may exchange Class Y shares of a fund, without an exchange fee, for Class Y
shares of another fund managed by SM&R. You also may exchange your Class Y
shares for shares of SM&R Investments, Inc.'s Primary Fund and Money Market
Fund, provided that you meet any minimum investment requirement for the shares
you wish to acquire. You cannot exchange shares of the Money Market Fund or
Primary Fund for Class B or C shares of another fund.
 
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 that are registered in the
        same name, address and, if applicable, taxpayer identification number;
 
    (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 a written exchange must meet the minimum investment
        requirement applicable to the shares of the fund that you would acquire
        through the exchange;
 
    (d) the minimum dollar amount of a telephone exchange is $500;
 
    (e) SM&R must have received full payment for the shares being exchanged;
 
                                       28
<PAGE>
    (f) 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);
 
    (g) any shares that you wish to exchange must have been held for at least
        ten (10) business days;
 
    (h) certificates representing shares, if any, are returned before such
        shares are exchanged; and
 
    (i)  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 funds and raise the funds' 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 invest in Class Y shares of the funds:
 
      - Individual Retirement Accounts (IRAs), which include traditional IRAs,
        Roth IRAs, Education IRAs, and SIMPLE IRAs,
 
      - Simplified Employee Pension Plans (SEPs),
 
                                       29
<PAGE>
      - 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 funds. 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 funds and will be automatically deducted
from each account. An individual considering a retirement plan may wish to
consult with an attorney or tax adviser.
 
DIVIDENDS, DISTRIBUTIONS, AND TAXES
 
DIVIDENDS. The Equity Income and Balanced Funds will pay dividends from
investment income, if any, quarterly, generally during the months of March,
June, September and December, and distribute capital gains, if any, in December.
The Growth Fund will pay dividends from investment income, if any, semi-annually
during the months of June and December and distribute capital gains, if any, in
December. Dividends from net investment income may include net short-term
capital gains, if any.
 
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.
 
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
 
                                       30
<PAGE>
in shares of the funds. 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 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.
Corporations may be entitled to take a dividends-received deduction for a
portion of certain dividends they receive. 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.
 
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 funds 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 the net asset value determined on the date the
request is received by SM&R in proper form. A
 
                                       31
<PAGE>
redemption request must be processed through your investment adviser or
broker-dealer.
 
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. Telephone
privileges are not available to shareholders automatically. 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 proceeds of the redemption are $500 or more and do not exceed
        $25,000; and
 
    (d) the security procedures discussed under "Special Purchase Plans And
        Services--Exchange Privilege" have been met.
 
These instructions may be changed only in writing, accompanied by a signature
guarantee and additional documentation may be required for corporations.
 
During times of economic turmoil or market volatility or as a result of severe
weather or a natural disaster, it may be difficult to contact SM&R by telephone
to institute a redemption or exchange.
 
SYSTEMATIC WITHDRAWAL PLAN. Each fund has a Systematic Withdrawal Plan
("Withdrawal Account"), which permits shareholders having an
 
                                       32
<PAGE>
account value of $50,000 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 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;
 
    (2) any required signature guarantees (see "Signature Guarantees" below);
        and
 
    (3) 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 SM&R in proper form for processing.
 
                                       33
<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 fund 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 fund 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.
 
REDEMPTION OF SMALL ACCOUNTS. The funds reserve 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 $10,000. You will be notified
that the value of your account is less than the required minimum and allowed at
least 60 days to make an additional investment to increase the value of your
account above the required minimum. The funds may, from time to time, change
such required minimum investment.
 
RIGHTS RESERVED BY THE FUNDS. The funds, acting directly or through SM&R,
reserve the right:
 
  - to waive or lower investment minimums;
 
  - to accept subsequent purchases by telephone from financial intermediaries;
 
  - 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;
 
                                       34
<PAGE>
  - 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 or has occurred;
 
  - 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;
 
  - to refuse to act on instructions not believed to be genuine; or
 
  - to eliminate duplicate mailings of fund material to shareholders who reside
    at the same address.
 
THE FUNDS AND MANAGEMENT
- -------------------------------------------------------------------
 
INVESTMENT ADVISER
 
Each fund's Board of Directors has delegated to Securities Management and
Research, Inc. ("SM&R"), the fund's investment adviser, the management of the
fund's 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. While the use of this
combined Prospectus subjects each fund to possible liability as the result of
statements or omissions regarding another fund, the Board of Directors of each
fund considers the benefits to the respective fund of using a combined
Prospectus to outweigh the risk.
 
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 banks, employee benefit plans, other
investment companies, banks, foundations and endowment funds.
 
                                       35

ADVISORY AGREEMENTS
 
GROWTH FUND. We deduct an investment advisory fee from the value of the shares
each day. We calculate this fee for the Growth Fund at the annual rate as
follows:
 
<TABLE>

          ON THE PORTION OF THE FUND'S                BASIC ADVISORY

<S>                                                <C>
Not exceeding $100,000,000                                  0.750%
Exceeding $100,000,000 but not exceeding
  $200,000,000                                              0.625%
Exceeding $200,000,000 but not exceeding
  $300,000,000                                              0.500%
Exceeding $300,000,000                                      0.400%
</TABLE>
 
We adjust the basic advisory fee rate by comparing the fund's investment
performance during the previous thirty-six (36) months with the investment
performance of the Lipper Growth Fund Index (the "Lipper Index") published by
Lipper Analytical Services, Inc. over the same period. Specifically, we adjust
the basic advisory fee each month by adding to or subtracting from such rate,
when appropriate, the applicable performance adjustment amount percentage shown
in the table below. The resulting advisory fee rate is then applied to the
average daily net asset value of the fund for the succeeding month. The advisory
fee for such month will be one-twelfth (1/12th) of the resulting dollar figure.

SM&R received total advisory fees from the Growth, Equity Income, and Balanced
Funds for the fiscal year ended December 31, 1997 of 0.60%, 0.69%, and 0.75%,
respectively, of each fund's average daily net assets. Each fund's advisory fees
may be higher than the fees paid by other mutual funds, but each fund believes
its fees are comparable to those paid by funds with the same or similar
investment objective.
 
ADMINISTRATIVE SERVICES
 
Pursuant to the Administrative Service Agreements with the funds, SM&R provides
all non-investment related management, executive, administrative, transfer
agent, and operational services to the funds. Under the agreements, SM&R
receives an administrative service fee from each fund at the annual rate of
average daily net asset values as follows:

In each fund's administrative service agreement, SM&R has agreed to pay (or to
reimburse each fund for) each fund's regular operating expenses in excess of
1.25% per year of such fund's average daily net assets. Regular operating
expenses include the advisory fee and
 
                                       37

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 total administrative service fees of 0.23% for the Growth Fund;
0.23% for the Equity Income Fund; and 0.25% for the Balanced Fund for the fiscal
year ended December 31, 1997 of each fund's average daily net assets.

The following financial highlights table is intended to help you understand the
Growth 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 Growth 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 Growth
Fund, which for the year ended through December 31, 1997 have been audited by
Tait, Weller & Baker, independent auditors, whose report, along with the Growth
Fund's financial statements, are incorporated by reference into the Statement of
Additional Information, which is available upon request. The information for
years ending December 31, 1996 and prior, has been audited by the Growth Fund's
former independent auditors. The information for the six month period ended June
30, 1998 was derived from unaudited financial statements of the Growth Fund.

APPENDIX A
 
(Description of Ratings Used in Prospectus)
- -------------------------------------------------------------------
 
BOND RATINGS
 
DESCRIPTION OF STANDARD & POOR'S CORPORATION'S LONG-TERM BOND (BONDS THAT EXTEND
LONGER THAN ONE YEAR) 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 impair the obligor's capacity or
      willingness to meet its financial commitment on the obligation.
 
DESCRIPTION OF MOODY'S INVESTOR'S SERVICE, INC.'S LONG-TERM BOND (BONDS THAT
EXTEND LONGER THAN ONE YEAR) 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
 
                                      A-1
<PAGE>
      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 larger than the 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.
 
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.
 
PREFERRED STOCK RATING
 
DESCRIPTION OF STANDARD & POOR'S CORPORATION'S PREFERRED STOCK RATING:
 
AAA     This is the highest rating that may be assigned by Standard & Poor's to
          a preferred stock issue and indicates an extremely strong capacity to
          pay the preferred stock obligations.
 
AA       A preferred stock issue rated "AA" also qualifies as a high-quality,
          fixed-income security. The capacity to pay preferred stock obligations
          is very strong, although not as overwhelming as for issues rated
          "AAA."
 
A        An issue rated "A" is backed by a sound capacity to pay the preferred
          stock obligations, although it is somewhat more susceptible to the
          adverse effects of changes in circumstances and economic conditions.
 
BBB      An issue rated "BBB" is regarded as backed by an adequate capacity to
          pay the preferred stock obligations. Whereas it normally exhibits
          adequate protection parameters, adverse economic conditions or
          changing circumstances are more likely to lead to a weakened capacity
          to
 
                                      A-2
<PAGE>
          make payments for a preferred stock in this category than for issues
          in the "A" category.
 
BB     Preferred stock rated "BB," "B," and "CCC" are regarded, on balance,
B      as predominantly speculative with respect to the issuer's capacity to pay
CCC    preferred stock obligations. "BB" indicates the lowest degree of
       speculation and "CCC" the highest. While such issues will likely have
       some quality and protective characteristics, these are outweighed by
       large uncertainties or major risk exposures to adverse conditions.
 
DESCRIPTION OF MOODY'S INVESTORS SERVICE, INC.'S PREFERRED STOCK RATING:
 
aaa   An issue which is rated "aaa" is considered to be a top-quality preferred
      stock. This rating indicates good asset protection and the least risk of
      dividend impairment within the universe of preferred stocks.
 
aa    An issue which is rated "aa" is considered a high-grade preferred stock.
      This rating indicates that there is a reasonable assurance the earnings
      and asset protection will remain relatively well maintained in the
      foreseeable future.
 
a     An issue which is rated "a" is considered to be an upper-medium grade
      preferred stock. While risks are judged to be somewhat greater then in the
      "aaa" and "aa" classification, earnings and asset protection are,
      nevertheless, expected to be maintained at adequate levels.
 
baa   An issue which is rated "baa" is considered to be a medium-grade preferred
      stock, neither highly protected nor poorly secured. Earnings and asset
      protection appear adequate at present but may be questionable over any
      great length of time.
 
ba    An issue which is rated "ba" is considered to have speculative elements
      and its future cannot be considered well assured. Earnings and asset
      protection may be very moderate and not well safeguarded during adverse
      periods. Uncertainty of position characterizes preferred stocks in this
      class.
 
b     An issue which is rated "b" generally lacks the characteristics of a
      desirable investment. Assurance of dividend payments and maintenance of
      other terms of the issue over any long period of time may be small.
 
FEDERAL FUNDS
 
As used in this Prospectus and in the Funds' Statement of Additional
Information, "Federal Funds" means a commercial bank's deposits in a Federal
Reserve Bank which can be transferred from one member bank's account to that of
another member bank on the same day. Federal Funds are considered to be
immediately available funds.

THE FUNDS
 
    The SM&R Growth Fund, Inc. (the "Growth Fund"), the SM&R Equity Income Fund,
Inc. (the "Equity Income Fund"), and the SM&R Balanced Fund, Inc. (the "Balanced
Fund") (each a "Fund" and collectively the "Funds") are registered under the
Investment Company Act of 1940, as amended (the "1940 Act" or the "Act") as
diversified, open-end management investment companies commonly known as mutual
funds. A mutual fund is a company in which a number of persons invest which in
turn invests in the securities of other companies. Each Fund is an open-end
investment company because it generally must redeem an investor's shares upon
request. Each Fund is a diversified investment company because it offers
investors an opportunity to reduce the risk inherent in all investments in
securities by spreading their investment over a number of companies. However,
diversification cannot eliminate such risks. Registration under the 1940 Act
does not imply any supervision by the Securities and Exchange Commission (the
"SEC") over the Funds' management or investment policies or practices.
 
    The Funds are each divided into six classes of shares (the "Classes") of
common stock designated as:
 
    - Class A (front-end load);
 
    - Class B (back-end load);
 
    - Class C (level load);
 
    - Class Y (institutional shareholders);
 
    - Class J (network); and
 
    - Class T (existing Class T shareholders and certain designated persons).
 
    These Classes of shares have different sales charges and distribution and
service (12b-1) fee structures. Each Class bears its own liabilities and its
proportionate share of the general liabilities of that Fund. A Multiple Class
Plan was adopted for each Fund pursuant to Rule 18f-3 under the 1940 Act.
 
    The Growth Fund was originally incorporated in Florida on March 5, 1953. The
Equity Income Fund was originally incorporated in Texas on July 15, 1969. The
Balanced Fund was originally incorporated in Texas on January 9, 1978.
 
    Each of these three funds was reincorporated under the laws of the State of
Maryland on August 23, 1989. Effective December 31, 1998, each fund adopted its
current name.
 
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 POLICIES
 
    Each Fund's investment objective and the following investment policies have
been adopted as fundamental policies. (A fundamental policy may not be changed
without the approval of shareholders.)
 
    Each Fund is subject to the following fundamental investment policies:
 
    1.  The Fund, 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.
<PAGE>
    2.  The Fund 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.  The Fund 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.  The Fund 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.  The Fund 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.  The Fund 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.
 
    7.  The Fund may not issue senior securities to the extent such issuance
       would violate applicable law.
 
    8.  The Fund 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.
 
    In addition to the above, the Balanced Fund has adopted, as a fundamental
policy, that it will be a "balanced fund."
 
    The above investment policies are fundamental policies that may be changed
by a 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 a Fund must approve any change to the foregoing policies 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.
 
    Any investment policy which involves a maximum percentage of securities or
assets shall not be considered to be violated unless an excess over the
percentage occurs immediately after an acquisition of securities or utilization
of assets and results therefrom. This applies to both the fundamental policies
(above) and the non-fundamental policies (below).
 
NON-FUNDAMENTAL INVESTMENT POLICIES
 
    GROWTH FUND.  The Board of Directors of the Growth Fund has adopted the
following non-fundamental investment policies. Non-fundamental investment
policies may be changed by the Board of Directors, without approval from
shareholders.
 
                                       2
<PAGE>
      1. The Fund will not invest more than 5% of the value of the net assets of
         the Fund, at the 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.
 
      2. The Fund will not 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.
 
      3. The Fund will not concentrate more than 25% of its net assets 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 policy, telephone, gas and
         electric and public utilities are each regarded as separate industries.
 
      4. The Fund will not 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. The Fund will not 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).
 
      5. The Fund will not 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.
 
      6. The Fund will not lend money or other assets (although this does not
         prevent the purchase of bonds or other corporate debt securities which
         are publicly distributed).
 
      7. The Fund will not engage in underwriting securities of other issuers.
 
      8. The Fund will not buy or sell real estate.
 
      9. The Fund will not invest in oil, gas or other mineral leases, rights or
         royalty contracts or in real estate or real estate limited
         partnerships.
 
     10. The Fund will not invest in real estate mortgage loans although it may
         invest in securities which are secured by real estate or real estate
         mortgages and securities of issuers which invest or deal in real estate
         and/or real estate mortgages, provided such securities meet the
         criteria set forth in the Prospectus.
 
     11. The Fund will not purchase or sell commodities or commodity contracts
         including future contracts.
 
     12. The Fund will not issue senior securities.
 
     13. The Fund may not purchase any security which is an "illiquid security"
         if more than 15% of the net assets of the Fund taken at market value
         would be invested in such securities.
 
     14. The Fund does not engage in the strategy of short sales of securities.
 
     15. The Fund will not write or purchase put and call options, or any
         combination thereof.
 
     16. The Fund will not invest in companies for the purpose of exercising
         control or management.
 
     17. The Fund will not invest in the securities of companies which have a
         record of less than three years continuous operation, including
         predecessor companies.
 
     18. The Fund will not invest in the securities of an issuer if more than
         1/2% interest in it is owned by an officer or director of the Fund or
         SM&R and such officers or directors together own more than 5% interest
         in such issuer.
 
                                       3
<PAGE>
     19. The Fund will not purchase the securities of any other investment
         company unless such purchases are made on the open market and do not
         exceed 5% of the Fund's total assets, taken at market, or unless such
         purchases are the result of a plan or merger and do not otherwise
         violate the applicable provisions of the Investment Company Act of
         1940. Such purchases may cause the Fund to indirectly incur additional
         advisory and administrative fees.
 
     20. Any warrants purchased by the Fund must be marketable warrants and the
         Fund's investment in warrants valued at the lower of cost or market,
         may not exceed 5% of the Fund's total assets. Not more than 2% of the
         Fund's total assets may be invested in warrants which are not listed on
         the New York or American Stock Exchange.
 
    EQUITY INCOME FUND.  The Board of Directors of the Equity Income Fund has
adopted the following non-fundamental investment policies, which may be changed
by the Board of Directors, without approval from shareholders.
 
      1. The Fund will not purchase the securities of any one issuer (other than
         those issued or guaranteed by the U.S. Government), if immediately
         after and as a result of such purchase the market value of the Fund's
         holding in the securities of such issuer exceeds 5% of the market value
         of the Fund's total assets. The Fund will not purchase the securities
         of an issuer if the purchase will cause the Fund to own more than 10%
         of the outstanding voting securities of the issuer.
 
      2. The Fund will not concentrate its investments in any particular
         industry or groups of industries; however, it may invest up to 25% of
         the value of its total assets in the securities of issuers in any one
         industry. Utility companies, for example, such as gas, electric, water
         and telephone companies will be considered as separate industries.
 
      3. The Fund will not borrow money except from banks for temporary,
         extraordinary or emergency purposes, and then only from a bank and not
         in excess of 5% of the value of its total assets and not for investment
         purposes.
 
      4. The Fund will not purchase securities on margin. The Fund will not
         pledge, mortgage or hypothecate any of its property.
 
      5. The Fund will not make loans to other persons except through the

         oil, gas or other mineral leases, rights or royalty contracts or in
         real estate or real estate limited partnerships.
 
      8. The Fund will not invest in real estate mortgage loans although it may
         invest in securities which are secured by real estate or real estate
         mortgages and securities of issuers which invest or deal in real estate
         and/or real estate mortgages, provided such securities meet the
         criteria set forth in the Prospectus.
 
      9. The Fund will not purchase or sell commodities or commodity contracts
         including future contracts.
 
     10. The Fund will not issue senior securities.
 
     11. The Fund may not purchase any security which is an "illiquid security"
         if more than 15% of the net assets of the Fund taken at market value
         would be invested in such securities.
 
     12. The Fund does not engage in the strategy of short sales of securities.
 
                                       4

         purchase of assets.
 
     16. The Fund will not purchase or retain securities of any issuer if any
         officer or director of the Fund or SM&R owns more than 1/2 of 1% of the
         securities of such issuer and such officers or directors together own
         more than 5% of the securities of such issuer.
 
     17. The Fund will not invest in securities of another investment company
         except pursuant to a plan of merger, consolidation or acquisition of
         assets approved by shareholders of the Fund.
 
     18. Any warrants purchased by the Fund must be marketable warrants and the
         Fund's investment in warrants valued at the lower of cost or market,

of Directors, without approval from shareholders.
 
      1. The Fund will not purchase the securities of any one issuer (other than
         those issued or guaranteed by the U.S. Government), if immediately
         after and as a result of such purchase the market value of the Fund's
         holding in the securities of such issuer exceeds 5% of the market value
         of the Fund's total assets.
 
      2. The Fund will not purchase the securities of an issuer if the purchase
         will cause the Fund to own more than 10% of the outstanding voting
         securities of the issuer.
 
      3. The Fund will not concentrate its investments in any one industry by
         investment of more than 25% of the value of its total assets in such
         industry. Utility companies, for example, such as gas, electric, water
         and telephone companies will be considered as separate industries.
 
      4. The Fund will not borrow money except that the Fund may borrow an
         amount up to 10% of its total assets to meet redemption requests and
         for the clearance of purchases and sales of portfolio securities (this
         borrowing provision is not for investment leverage but solely to
         facilitate management of the portfolio to enable the Fund to meet
         redemption requests where the liquidation of portfolio securities is
         deemed to be disadvantageous or inconvenient and to obtain such
         short-term credits as may be necessary for the clearance of purchases
         and sales of portfolio securities; all borrowings at any time
         outstanding will be repaid before any additional investments are made;
         the Fund will not mortgage, pledge or hypothecate any assets in
         connection with any such borrowing in excess of 15% of the Fund's total
         assets.

      6. The Fund will not engage in underwriting securities issued by other
         persons.
 
      7. The Fund will not purchase or sell commodities or commodity contracts
         including future contracts.
 
                                       5
<PAGE>
      8. The Fund will not issue senior securities.
 
      9. The Fund will not invest in oil, gas or other mineral leases, rights on
         royalty contracts or in real estate or real estate limited
         partnerships.
 
     10. The Fund will not invest in real estate mortgage loans although it may
         invest in securities which are secured by real estate or real estate
         mortgages and securities of issuers which invest or deal in real estate
         and/or real estate mortgages, provided such securities meet the
         criteria set forth in the Prospectus.
 
     11. The Fund does not engage in the strategy of short sales of securities.
 
     12. The Fund will not invest in other companies for the purpose of
         exercising control of management.
 
     13. The Fund will not purchase the securities of any other investment
         company except in a regular transaction in the open market. Such
         purchases may cause the Fund to indirectly incur additional advisory
         and administrative fees.
 
     14. The Fund may not purchase any security which is an "illiquid security"

     15. The Fund will not purchase any securities as to which it would be
         deemed a statutory underwriter under the Securities Act of 1933.
 
     16. The Fund will not purchase the securities of any issuer the business of
         which has been in continuous operation for less than three (3) years
         (however, it is the Fund's operating policy not to invest in any
         business which has not been in continuous operation for at least five
         (5) years).
 
     17. The Fund will not retain investments in the securities of any issuer if
         directors or officers of the Fund or certain other "interested" persons
         own more than 5% of such securities.
 
     18. Any warrants purchased by the Fund must be marketable warrants and the
         Fund's investment in warrants valued at the lower of cost or market,
         may not exceed 5% of the Fund's total assets. Not more than 2% of the
         Fund's total assets may be invested in warrants which are not listed on
         the New York or American Stock Exchange.
 
    The Balanced Fund does not presently invest in private placement securities.
 
INVESTMENT TECHNIQUES
 
U.S. GOVERNMENT OBLIGATIONS
 
    The Funds may invest in United States Government obligations. These
instruments are debt obligations issued by agencies or authorities controlled or
supervised by and acting as instrumentalities of the U.S. Government established
under authority granted by Congress. Such obligations include, but are not
limited to, Government National Mortgage Association, The Tennessee Valley
Authority, The Bank for Cooperatives, Federal Intermediate Credit Banks, Federal
Home Loan Banks, Federal Land Banks and The Federal National Mortgage
Association. Some obligations of U.S. Government agencies, authorities and other
instrumentalities are supported by the full faith and credit of the U.S.
Treasury; others by the rights of the issuer to borrow from the Treasury; 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. Obligations of the Government National
Mortgage Association are supported by the full faith and credit of the U.S.
Treasury; obligations of the other agencies, authorities and other
instrumentalities shown above are supported only by the credit of the issuers.
 
                                       6
<PAGE>
    The Funds' adviser will invest in U.S. obligations not backed by the "full
faith and credit" of the U.S. government only when, in its opinion, the credit
risk is minimal. SM&R does not presently intend to invest any significant amount
in such obligations and would do so in the future only to increase a Fund's
liquidity on a short-term basis during adverse and unusual market conditions.
 
INVESTMENT IN COVERED CALL OPTIONS
 
    Although there is no present intent to do so, the Balanced Fund may write
covered call option contracts provided that the option is listed on a domestic
securities exchange and that no option will be written if, as a result, more
than 25% of the Balanced Fund's assets are subject to call options. A covered
call option is an option on a security which the Balanced Fund owns or can
acquire by converting a convertible security it owns. The purchaser of the
option acquires the right to buy the security from the Balanced Fund at a fixed
exercise price at any time prior to the expiration of the option, regardless of
the market price of the security at that time. A security on which an option has
been written will be held in escrow by the Balanced Fund's custodian until the
option expires, is exercised, or a closing purchase transaction is made. The
Balanced Fund thus foregoes the opportunity to profit from an increase in the
market price in the underlying security above the exercise price, in return for
the premium it receives from the purchaser of the option. The Balanced Fund's
management believes that such premiums will maximize the Balanced Fund's return
without subjecting it to substantial risks.
 
    The Balanced Fund will purchase call options only to close out a position in
an option written by it. In order to close out a position the Balanced Fund will
make a "closing purchase transaction" if such is available. In such a
transaction, the Balanced Fund will purchase a call option on the same security
with the same exercise price and expiration date as the call option which it has
previously written. When a security is sold from the Balanced Fund's portfolio
against which a call option has been written, the Balanced Fund will effect a
closing purchase transaction so as to close out any existing call option on that
security. The Balanced Fund will realize a profit or loss from a closing
purchase transaction if the amount paid to purchase a call option is less or
more than the amount received as a premium from the writing thereof. A closing
purchase transactions cannot be made if trading in the option has been
suspended.
 
    The premium received by the Balanced Fund upon writing a call option will
increase the Balanced Fund's assets, and a corresponding liability will be
recorded and subsequently adjusted from day to day to the current value of the
option written. For example, if the current value of the option exceeds the
premium received, the excess would be an unrealized loss and, conversely, if the
premium exceeds the current value, such excess would be an unrealized gain. The
current value of the option will be the last sales price on the principal
exchange on which the option is traded or, in the absence of any transactions,
the mean between the closing bid and asked price.
 
COLLATERALIZED MORTGAGE OBLIGATIONS
 
    The Balanced 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 Balanced 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.
 
                                       7
<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.
 
REPURCHASE AGREEMENTS
 
    Each fund may purchase repurchase agreements either for defensive purposes
due to market conditions or to generate income from its excess cash balances. In
a repurchase agreement, a fund purchases a U.S. government security subject to
resale to a bank or dealer at an agreed upon price and date. These repurchase
agreements will be entered into only with government securities dealers
recognized by the Federal Reserve Board or with member banks of the Federal
Reserve System. A repurchase agreement may be considered a loan collateralized
by securities. The resale price reflects an agreed upon interest rate effective
for the period the instrument is held by a Fund and is unrelated to the interest
rate on the underlying instrument. In these transactions, the securities
acquired by a Fund (including accrued interest earned thereon) must have a total
value in excess of the value of the repurchase agreement and are held by the
Fund's Custodian Bank until repurchased. During the holding period, the seller
must provide additional collateral if the market value of the obligation falls
below the repurchase price. The custodian for the fund purchasing such agreement
will take title to, or actual delivery of the security. A default by the seller
might cause a fund to experience a loss or delay in the liquidation of the
collateral securing the repurchase agreement. A fund might also incur
disposition costs in liquidating the collateral. The funds will purchase only
repurchase agreements maturing in seven (7) days or less.
 
    The use of repurchase agreements involves certain risks. For example, if the
other party to the agreement defaults on its obligations to repurchase the
underlying security at a time when the value of the security has declined, a
Fund may incur a loss upon disposition of the security. If the other party to
the agreement becomes insolvent and subject to liquidation or reorganization
under the Bankruptcy Code or other laws, a court may determine that the
underlying security is collateral for a loan by a Fund not within the control of
that Fund and therefore the realization by that Fund on such collateral may be
automatically stayed. Finally, it is possible that a Fund may not be able to
substantiate its interest in the underlying security and may be deemed an
unsecured creditor of the other party to the agreement. While the Funds'
management acknowledges these risks, it is expected that they can be controlled
through careful monitoring procedures.
 
LENDING OF SECURITIES
 
    Although there is no present intent to do so, the Balanced Fund may lend its
portfolio securities to qualified institutional investors who need to borrow
securities in order to complete certain transactions, such as covering short
sales, avoiding failures to deliver securities or completing arbitrage
operations. By lending its portfolio securities, the Balanced Fund attempts to
increase its income through the receipt of interest on the loan. Any gain or
loss in the market price of the securities loaned that might occur during the
term of the loan would be for the account of the Balanced Fund. The Balanced
Fund may lend its portfolio securities to qualified brokers, dealers, banks or
other financial institutions, so long as the terms the structure and the
aggregate amount of such loans are not inconsistent with the 1940 Act, or the
Rules and Regulations or interpretations of the SEC thereunder, which currently
require that (a) the borrower pledge and maintain with the Balanced Fund
collateral consisting of cash, a letter of credit issued by a domestic United
States bank, or securities issued or guaranteed by the United States Government
having a value at all times not less than 100% of the value of the securities
loans, (b) the borrower add to such collateral whenever the price of the
securities loaned rises (i.e., the borrower "marks to the market" on a daily
basis), (c) the loans be made subject to termination by the
 
                                       8
<PAGE>
Balanced Fund at any time, and (d) the Balanced Fund receive reasonable interest
on the loans (which may include the Balanced Fund's investing any cash
collateral in interest bearing short-term investments), any distribution on the
loaned securities and any increase in their market value.
 
COMMERCIAL PAPER
 
    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 funds will not invest in variable amount master
demand notes.
 
ILLIQUID SECURITIES
 
    Each Fund may invest up to 15% 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 these 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 SM&R 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 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.
 
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
 
                                       9
<PAGE>
held by a Fund do not benefit materially from insurance from the Federal Deposit
Insurance Corporation.
 
AMERICAN DEPOSITORY RECEIPTS ("ADRS")
 
    ADRs are U.S. dollar-denominated securities of foreign corporations which
are traded in the U.S. on national securities exchanges or over-the-counter and
are issued by domestic banks. The banks act as custodian of the shares of the
foreign stock and collect dividends on the stock which are either reinvested or
distributed to the ADR holder in U.S. dollars. While ADRs are not considered
foreign securities, they may entail certain political, economic and regulatory
risks. Such risks may include political or social instability, excessive
taxation and limitations on the removal of funds or other assets which could
adversely affect the value of a fund's investments. The economies of many
countries in which a fund may invest may not be as developed as the U.S. economy
and may be subject to significantly different forces. Foreign companies are not
registered with the SEC and are not generally subject to the regulatory controls
imposed on U.S. issuers. Consequently, there is generally less public
information available on foreign securities. Foreign companies are not subject
to uniform accounting, auditing, and financial reporting standards. Income from
foreign securities owned may be reduced by a withholding tax at the source,
which tax would reduce income payable to a fund's shareholders.
 
PORTFOLIO TURNOVER
 
    Portfolio turnover for a Fund is calculated by dividing the lesser of annual
purchases or sales of portfolio securities by the monthly average of the value
of the Fund's portfolio securities excluding securities whose maturities at the
time of purchase are one year or less. A 100% portfolio turnover rate would
occur, for example, if all of the Fund's portfolio securities were replaced
within one year. In general, it is intended that portfolio changes in the Funds
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. However, purchases and sales of portfolio securities for the
Balanced Fund are made at such times and in such amounts as are deemed advisable
in light of market, economic and other conditions, irrespective of the volume of
portfolio turnover. 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.
 
    The portfolio turnover rates for the Funds for past three fiscal years are
as follows:

MANAGEMENT OF THE FUNDS
 
    The Board of Directors of each Fund has the responsibility for the overall
management of that Fund, including general supervision and review of its
investment activities. The directors, in turn, elect
 
                                       10

the officers of each Fund who are responsible for administering day-to-day
operations of the Fund. While the use of this combined Statement of Additional
Information subjects each Fund to possible liability as the result of statements
or omissions regarding another Fund, the Board of Directors of each Fund
considers the benefits to the respective Fund of using a combined Statement of
Additional Information to outweigh the risk.
 
OFFICERS AND DIRECTORS OF THE FUNDS
 
    Information about each of the officers and directors of the Funds is set
forth below. Unless otherwise specifically noted, each has had the same or
similar employment or position for at least the past five years and occupies the
identical position with all three Funds. Unless otherwise indicated, the address
of an officer or director is 2450 South Shore Boulevard, Suite 400, League City,

    Directors, officers, full-time employees, and other affiliated persons of
the Funds, SM&R, or American National may purchase Class T shares of the Funds
at net asset value per share without the imposition of any sales charge. (For
more information, see "Eligible Purchasers of Class T Shares" and "Waiver of
Initial Sales Charge for Certain Purchasers" in the Prospectus for Class T
shares.) The sales charge is waived on shares sold to directors and affiliated
persons 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 each Fund's Code of Ethics.
 
PERSONAL INVESTING BY PORTFOLIO MANAGERS
 
    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 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.
 
    4.  Any beneficial interest in a security for which a written approval is
       first obtained from the President and Chief Executive Officer may be
       traded or held.
 
    Furthermore, portfolio managers are prohibited from acquiring any security
of an initial public offering and must receive prior written approval from
SM&R's Chief Executive Officer before investing in any private placement
securities.
 
PERSONAL INVESTING BY OTHER SM&R OFFICERS AND EMPLOYEES
 
    Officers and employees of SM&R 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 4, 1998, no person owned 5% or more of the outstanding shares
of the Growth Fund or the Equity Income Fund (either of record or beneficially).
As of December 4, 1998, American National Insurance Company ("American
National") and SM&R were the only shareholders known to the Balanced Fund to own
five percent (5%) or more of its outstanding shares. On that date, American
National owned approximately 15.14% and SM&R owned approximately 8.54% of the
Balanced Fund's common stock. While such ownership does not directly affect a
shareholder's voting rights, it obviously gives American National and SM&R a
strong voice in the Balanced Fund's affairs. As a practical
 
                                       14
<PAGE>
matter, such ownership means that passage of a shareholder proposal is unlikely
without American National's or SM&R's vote therefor.
 
    The officers and directors of each Fund as a group owned less than 1% of the
outstanding shares of each Fund as of December 4, 1998.
 
INVESTMENT ADVISORY AND OTHER SERVICES
 
CONTROL AND MANAGEMENT OF SM&R
 
    SM&R has been the investment adviser, manager and underwriter of the Growth
Fund since 1966, of the Equity Income Fund since it began business in 1969, and
of the Balanced Fund since it began business in 1978. SM&R acts pursuant to a
written agreement periodically approved by the directors and shareholders of
each Fund. SM&R is also the investment adviser, manager and underwriter of
American National Investment Accounts, Inc. and SM&R Investments, Inc.
 
    SM&R is a wholly-owned subsidiary of American National, a Texas life
insurance company with its principal offices at 2450 South Shore Boulevard,
League City, Texas 77573. As of December 4 ,1998, the Moody Foundation, a
charitable foundation established for charitable and educational purposes, owned
approximately 23.7% of American National's common stock and the Libbie S. Moody
Trust, a private trust, owned approximately 37.6% of such shares. The trustees
of the Moody Foundation are Robert L. Moody, Frances Moody Newman, and Ross R.
Moody. The Moody National Bank of Galveston (the "Bank") is trustee of the
Libbie S. Moody Trust.
 
    The Bank's controlling stockholder is Moody Bank Holding Company, Inc.
("MBHC"). Moody Bancshares, Inc. ("Bancshares") is the sole shareholder of MBHC.
As of December 4, 1998, the Three R Trusts (trusts established by Robert L.
Moody for the benefit of his children) owned 100% of Bancshares' Class B stock
(which elects a majority of Bancshares' and MBHC's Directors) and 47.5% of its
Class A stock. The trustee of the Three R Trusts is Irwin M. Herz, Jr., who is
also a director of American National and a partner in Greer, Herz & Adams,
L.L.P. Greer, Herz & Adams, L.L.P., 18th Floor, One Moody Plaza, Galveston,

INVESTMENT ADVISORY AGREEMENT
 
    Under an Investment Advisory Agreement (an "Advisory Agreement") between
each Fund and SM&R dated November 30, 1989, SM&R acts as investment adviser for
and provides certain administrative services to the Funds.
 
    As investment adviser, SM&R manages the investment and reinvestment of each
Fund's assets, including the placing of orders for the purchase and sale of
portfolio securities. SM&R provides and evaluates economic, statistical and
financial information to formulate and implement Fund investment programs. All
investments are reviewed quarterly by each Fund's Board of Directors to
determine whether or not such investments are within the policies, objectives
and restrictions of each Fund.
 
    Each Fund's Advisory Agreement was effective on November 30, 1989 and will
continue in effect from year to year only so long as such continuance is
specifically approved at least annually by its Board of Directors or by vote of
a majority of the outstanding voting securities of the Fund, and, in either
case, by the specific approval of a majority of directors who are not parties to
the Advisory 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. Absent proposed changes, it is the policy of Fund
management to submit continuation of the Advisory Agreements annually only to
the Funds' Boards of Directors for their approval or disapproval. Each Fund's
Advisory Agreement was most recently approved by its Board of Directors on
November 19, 1998, and by its shareholders on November 16, 1989. Each Fund's
Advisory Agreement may be terminated without penalty by vote of its Board of
Directors or by vote of the holders of a majority of the outstanding voting
securities of the Fund, or by SM&R, upon sixty (60) days written notice and will
automatically terminate if assigned.
 
    As used herein, the term "majority" when referring to approval to be
obtained from shareholders means the vote of the lesser of (1) 67% of the Fund's
shares present at a meeting if the owners of more than 50% of the outstanding
shares are present in person or by proxy; or (2) more than 50% of the Fund's
outstanding shares.
 
    Under the Advisory Agreement, SM&R receives from each Fund an investment
advisory fee (the "Basic Advisory Fee") for acting as investment adviser
computed by applying to the average daily net asset value of each Fund each
month one-twelfth of the annual rate as follows:

</TABLE>
 
                                       16
<PAGE>
In addition, the Advisory Agreement for the Growth Fund also provides for an
upward or downward adjustment of the Basic Advisory Fee based upon the
investment performance during the previous thirty-six (36) monthly periods of
the Growth Fund compared to the Lipper Growth Fund Index (the "Lipper Index")
published by Lipper Analytical Services, Inc., as discussed below.
 
    The fees payable under each Fund's Advisory Agreement may be higher than the
fees paid by other mutual funds, but each Fund believes its fees are comparable
to those paid by funds with the same or similar investment objective.
 
    The average daily net asset value of each Class of each Fund shall be
computed by adding the net asset values computed by SM&R each day during the
month and dividing the resulting total by the number of days in the month. The
net asset value per share of each Class of Fund shares shall be determined each
day by adding the market value of its portfolio securities and other assets,
subtracting liabilities and dividing the result by the number of Class shares
outstanding. Expenses and fees of each Fund, including the advisory and
administrative service fee, will be accrued daily and taken into account in
determining net asset value. The portfolio securities of each Fund will be
valued as of the close of trading on each day when the New York Stock Exchange
is open for regular trading. Securities listed on national securities exchanges
will be 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 will be determined on the basis of the latest bid prices
therefor on such day. If no quotations are available for a security or other
property, it will be valued at fair value as determined in good faith by SM&R on
a consistent basis.
 
PERFORMANCE ADJUSTMENT OF BASIC ADVISORY FEE FOR GROWTH FUND
 
    Under the Growth Fund's Advisory Agreement, the Basic Advisory Fee annual
rate shown above will be adjusted each month by adding to or subtracting from
such rate, when appropriate, the applicable performance adjustment amount
percentage shown in the table below. The resulting advisory fee rate will then
be applied to the average daily net asset value of the Growth Fund for the
succeeding month. The advisory fee for such month will be one-twelfth ( 1/12th)
of the resulting dollar figure.
 
    The performance adjustment amount shall vary with the Growth Fund's
performance as compared to the Lipper Index as shown by the following table:

    The performance period is calculated as of the last Thursday of each January
through November and the last business day of each December. The time period
between the last business day in December and the last Thursday in January, the
ten (10) time periods between the last Thursday in January through October and
the last Thursday of the immediately succeeding month, and the time period
between the last Thursday in November and the last business day in December
shall be referred to herein as the "Monthly Periods". The performance period
which forms the basis for each monthly fee adjustment calculation shall end on
each such last Thursday and last business day and shall be the immediately
preceding thirty-five (35) Monthly Periods plus the current Monthly Period.
 
    To determine how the Growth Fund's performance compares to the Lipper Index,
SM&R will determine a monthly percentage change for the Growth Fund and for the
Lipper Index. These monthly percentage changes will be calculated for each
Monthly Period other than January by dividing the year-to-date percentage
changes through the end of each of the Monthly Periods by the year-to-date
percentage changes through the end of the preceding Monthly Period. The monthly
percentage and the year-to-date percentage change for January will always be the
same and will not have to be calculated separately. A cumulative percentage
change for the Performance Period will then be calculated by compounding the
monthly percentage changes for the preceding thirty-five (35) Monthly Periods
and multiplying that product by the current Monthly Period's percentage change.
After such cumulative percentage change has been calculated for the Growth Fund
and the Lipper Index, such percentage changes are then compared. If the
percentage differential resulting from such comparison is less than .10%, no
performance adjustment shall be made. If such percentage differential is .10%,
or more, such differential shall be the percentage used in the Percentage
Performance Compared To Lipper Index table above. For example, if the percentage
differential resulting from such comparison is .07%, no performance adjustment
shall be made and the advisory fee shall be equal to the Basic Advisory Fee
annual rate. If such percentage differential is 2.5% above the Lipper Index, a
performance adjustment equal to .06% shall be made and the Basic Advisory Fee
shall be increased from .75% to .81%. If such percentage differential is 2.5%
below the Lipper Index, a performance adjustment equal to .06% shall be made and
the Basic Advisory Fee shall be decreased from .75% to .69%.
 
    Those shareholders who prefer to use basis points rather than percentage
points when analyzing the Growth Fund's performance compared to the Lipper Index
should convert each 1.00% in the Percentage Performance Compared To Lipper Index
column in the above table to 100 basis points.
 
    The adjustment to the Basic Advisory Fee will not be cumulative. An
increased fee will result even though the performance of the Growth Fund over
some period of time shorter than the Performance Period has been behind that of
the Lipper Index and even if the net asset value of the Growth Fund's shares has
decreased. Conversely, a reduction in the Basic Advisory Fee will be made for a
month even though the performance of the Growth Fund over some period of time
shorter than the Performance Period has been ahead of that of the Lipper Index
and even if the net asset value of the Growth Fund's shares has increased.
 
    As indicated above, the Growth Fund's expenses (including the monthly basic
advisory fee and administrative service fee) and the performance adjustment for
each performance fee period will be computed and accrued daily and taken into
account in computing the daily net asset value of a Growth Fund share. However,
expenses in excess of the maximum expense limitation shall not be accrued for
the purpose of computing the daily net asset value of a Growth Fund share.
 
    In the case of termination of the Advisory Agreement during any Monthly
Period, the fee for that Monthly Period shall be reduced proportionately on the
basis of the number of calendar days during which it is in effect for that
Monthly Period. The fee rate will be computed on the basis of and applied to net
assets averaged over that Monthly Period ending on the last business day on
which the Advisory Agreement is in effect. The amount of any performance
adjustment to the Basic Advisory Fee will be computed on the basis of the
thirty-six (36) Monthly Periods ending on the last business day on which
 
                                       18
<PAGE>
the Advisory Agreement is in effect provided that if the Advisory Agreement has
been in effect less than thirty-six (36) Monthly Periods, the computation will
be made on the basis of the period of time during which it has been in effect.
 
ADVISORY FEES PAID
 
    For the past three fiscal years, SM&R received investment advisory fees from

ADMINISTRATIVE SERVICE AGREEMENT
 
    Under an Administrative Service Agreement between each Fund and SM&R dated
November 30, 1989, as amended on November 19, 1998, SM&R provides all
non-investment related management, executive, administrative and operational
services to each Fund. Pursuant to the Administrative Service Agreement, SM&R
also acts as transfer agent for the Funds' authorized and issued shares and as
dividend disbursing agent.
 
    In its capacity as administrator under the Administrative Service Agreement,
SM&R furnishes and pays for the services of all officers and employees necessary
to perform the executive, administrative, clerical and bookkeeping functions of
the Funds. SM&R's duties as administrator include, among other things:
administering the Funds' affairs; maintaining office facilities; processing
purchase orders and redemption requests; furnishing statistical and research
data; and providing clerical, accounting, data processing, bookkeeping and
certain other services required by each Fund.
 
    In its capacity as transfer agent and dividend disbursing agent under the
Administrative Agreement, SM&R's duties include, but are not limited to:
dividend disbursements and transfer agency services; maintaining shareholder
accounts; preparing shareholder meeting lists and mailing and tabulating
proxies; mailing shareholder reports and other materials to shareholders; tax
withholding; and "blue sky" related services.
 
    Under each Administrative Service Agreement, SM&R receives from each Fund an
administrative service fee for providing administrative services. The fee is
computed by applying to the average daily net asset value of the Fund each month
one-twelfth of the annual rate as follows:

EXPENSES BORNE BY THE FUNDS
 
    Each Fund has agreed to pay other expenses incurred in the operation of the
Fund, such as interest, taxes, commissions and other expenses incidental to
portfolio transactions, SEC fees, fees of the Custodian (see "CUSTODIAN"
herein), auditing and legal expenses, fees and expenses of qualifying Fund
shares for sale and maintaining such qualifications under the various state
securities laws where Fund shares are offered for sale, fees and expenses of
directors not affiliated with SM&R, costs of maintaining corporate existence,
costs of printing and mailing prospectuses and shareholder reports to existing
shareholders and expenses of shareholders' meetings.
 
    SM&R has agreed in its Administrative Service Agreement with each Fund to
pay (or to reimburse each Fund for) each Fund's regular operating expenses of
any kind, exclusive of interest, taxes, commissions, Class Specific Expenses,
other expenses incidental to portfolio transactions, and extraordinary expenses
beyond SM&R's control, but including the basic advisory fee, in excess of 1.25%
per year of each Fund's average daily net assets. Such reimbursements, when
required, will be made monthly. No reimbursement to the Equity Income and Growth
Funds under the 1.25% expense limitation was required for the fiscal years ended
December 31, 1995, 1996 and 1997. During the fiscal years ended December 31,
1995, 1996, and 1997, SM&R reimbursed $40,894, $29,344, and $24,234,
respectively, in excess expenses to the Balanced Fund.
 
PORTFOLIO TRANSACTIONS AND BROKERAGE ALLOCATION
 
    SM&R, which supervises each Fund's investments, is responsible for effecting
portfolio transactions through eligible securities brokers and dealers, subject
to the general supervision of each Fund'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 Fund 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 evaluates the
brokerage fees paid by the 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 are
always used by SM&R in connection with the Funds. While SM&R is able to fulfill
its obligation to each Fund without such information, its expenses might be
materially
 
                                       20
<PAGE>
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 American National
Investment Accounts, Inc., SM&R Investments, Inc., 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.
 
    Consistent with the Conduct Rules of the National Association of Securities
Dealers, and subject to seeking the best price and execution, each Fund may give
consideration to sales of shares of each Fund as a factor in the selection of
brokers and dealers to execute Fund portfolio transactions. For the past three
fiscal years, SM&R paid brokerage fees on the purchase and sale of portfolio
securities for each Fund of the following approximate amounts:

    No brokerage commissions have been paid during the three most recent fiscal
years to: (i) any broker that is an affiliated person of the Funds or an
affiliated person of that person; or (ii) any broker an affiliated person of
which is an affiliated person of the Funds or SM&R.
 
    The Funds, the American National Investment Accounts, Inc., and SM&R
Investments, Inc., for which SM&R is also investment adviser, may own securities
of the same companies from time to time. However, Each Fund's portfolio security
transactions will be conducted independently, except when decisions are made to
purchase or sell portfolio securities of the Funds, the American National
Investment Accounts, Inc., and SM&R Investments, Inc., simultaneously. In such
event, the transactions will be averaged as to price and allocated as to amount
(according to the proportionate share of the total combined commitment) in
accordance with the daily purchase or sale orders actually executed.
 
    Each Fund's Board of Directors 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 the Funds,
which in other cases these practices could produce better executions.
 
DESCRIPTION OF FUND SHARES
 
    Each of the Funds has authorized capital stock of two billion common shares
with a par value of $0.01 each. The Funds are each divided into six Classes of
shares of common stock designated as:
 
    - Class A (front-end load);
 
    - Class B (back-end load);
 
    - Class C (level load);
 
    - Class Y (institutional shareholders);
 
    - Class J (network); and
 
    - Class T (existing Class T shareholders and certain designated persons).
 
                                       21
<PAGE>
    The shares of each Fund, 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 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 a 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 fees ("12b-1 fees") of that Class and any
Class-specific expenses. Class B and Class C shares are subject to higher 12b-1
fees, which will cause such Classes to have a higher expense ratio and pay lower
dividends than the Class A shares.
 
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 or amendment of the
investment advisory contract, all shares of each Fund vote together, with each
share having one vote. 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 generally are required for approval of the proposal.
 
PURCHASE, REDEMPTION AND PRICING OF SHARES
 
PURCHASING SHARES
 
    Shares of each Fund may be purchased at a public offering price which is
based on the net asset value of each share of the Fund next determined plus a
sales charge, if any. Remittances for additional investments may be submitted
directly to SM&R. Except for certain systematic investment programs (see
"SPECIAL PURCHASE PLANS" herein), the minimum initial investment is $100 and
additional shares may be purchased through investment of $20 or more at any time
thereafter.
 
    Certificates representing shares purchased are not issued. Investors have
the same ownership rights with respect to shares purchased as if certificates
had been issued. A confirmation will be sent to the investor promptly after each
share purchase.
 
    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 Funds reserve 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 applicable Funds.
 
DETERMINATION OF NET ASSET VALUE
 
    The net asset value per share of each Class of each Fund is determined by
adding the market value of the Class' portfolio securities and other assets,
subtracting liabilities, and dividing the result by the number of the Class
shares outstanding. Expenses and fees of each Class of a Fund, including the
advisory fee and the expense limitation reimbursement, if any, are accrued daily
and taken into account
 
                                       22
<PAGE>
in determining net asset value. The portfolio securities of the Funds are valued
as of the close of trading on each day that the New York Stock Exchange is open
for trading. 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 on such exchange. The value of unlisted
securities is determined on the basis of the latest bid prices therefor on such
day. 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 each Fund (or
their delegate) on a consistent basis.
 
DETERMINATION OF OFFERING PRICE
 
    Full and fractional shares are purchased at the offering price, which is the
net asset value next determined after receipt of a purchase order plus the 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 League
City, Texas prior to 3:00 p.m. Central Time, on any day that the New York Stock
Exchange is open for trading, will be executed at the applicable offering price
determined on that day. Purchases received by SM&R thereafter will be executed
at the offering price determined on the next day that the New York Stock
Exchange is open for trading.
 
    SM&R is not in receipt of purchase (and redemption or transfer) orders given
to a dealer until the dealer transmits the order to SM&R and SM&R actually
receives the order at its League City office. It is the responsibility of any
such dealer and not SM&R to establish procedures to assure that orders received
before the close of the Exchange on an SM&R business day will be reported to
SM&R before SM&R's close of business on that same day.
 
    CLASS T SHARES (EXISTING SHAREHOLDERS).  The offering price of the Class T
shares is the net asset value per share plus an initial sales charge of up to
5.75% of the public offering price. For amounts invested over certain levels, or
"breakpoints" (beginning at $50,000), 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 "Reduction and/or
Waiver of Initial Sales Charges" 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.
 
    The offering price of Class T shares is the next determined net asset value
plus a sales charge, if applicable (expressed as a percentage of the offering
price) shown in the following table:

    CLASS A SHARES (FRONT-END LOAD).  Class A shares are subject to an initial
sales charge of up to 5.00% 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. 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. 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
"Reduction and/or Waiver of Initial Sales Charges" below and "Sales Charge
Reductions and Waivers" in the Prospectuses.

    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.
 
    Each Class B share converts automatically to Class A shares of equal dollar
value after the investor has owned 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.
 
                                       24
<PAGE>
The conversion benefits shareholders because Class A shares are subject to a
lower ongoing Distribution Fee. If an investor converts Class B shares 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 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 Funds offered
through certain financial intermediaries (such as broker-dealers and investment
advisers) that have distribution agreements with SM&R. Class Y shares are
available to institutions and certain other investors, as described in the
Prospectus for the Class Y shares. Class Y shares are offered at net asset value
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 is that Class' net asset value.
 
    CLASS J SHARES.  Class J shares of the Funds are offered through mutual fund
"supermarkets" that have distribution agreements with SM&R. 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 is
that Class' net asset value. Class J shares are subject to an annual 12b-1 fee
of 0.75% 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 or Class A shares. To qualify, the investor may combine
concurrent purchases of Class T and Class A shares of a fund managed by SM&R at
the respective sales charges applicable to each. 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
agreements for their minor children; (3) A trustee or fiduciary of a single
trust estate or single fiduciary account; (4) 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 (5) Employees (or employers on
behalf of employees) under any employee benefit plan not qualified under Section
401 of the Internal Revenue Code.
 
    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 Funds 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 Funds' prospectuses available
to individual investors or employees, forwarding investments by such employees
to the Funds, and the like.
 
    These discounts through concurrent purchases are applicable both to single,
lump sum purchases made under the provisions of the preceding paragraphs and to
qualified investments under a "Letter of Intent" or under the "Accumulation
Privilege" as described below.
 
    THE EDUCATION FUNDING INVESTMENT ACCOUNT PROGRAM.  The following sales
charge breakpoints apply to purchases made by individuals investing in Class A
or Class T shares of the Funds through the use of The Education Funding
Investment Account Program as well as the Education IRA. These breakpoints
differ from the standard breakpoints in two respects: (1) investments in Class A
or T shares of less than $100,000 are subject to a lower initial sales charge,
and (2) investments in Class A

*   Class A shares are subject to a CDSC of 1.00% on shares redeemed within 13
    months of purchase.
 
    The Education Funding Investment Account Program is a service expressly
created to help investors accumulate funds for their children's or
grandchildren's college education. The maximum sales charge is 4.5% on the
purchase of Class A or T shares of the Funds. To participate in this special
plan, investors must complete the special Education Funding Investment Account
application designed specifically for the Program.
 
    DISCOUNTS THROUGH A RIGHT OF ACCUMULATION.  If you already own Class T or
Class A shares of a fund managed by SM&R, on which you paid a front-end sales
load, you may be able to receive a discount when you buy additional shares. The
current net asset value of the shares you already own may be
"accumulated"--I.E., combined together with the dollar amount being invested--to
achieve quantities eligible for discount.
 
    LETTER OF INTENT.  You may qualify immediately for a reduced sales charge on
purchases of Class T 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 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,
and previously subject to a front-end sales load, may also be included in the
aggregate amount of an investment covered by a Letter of Intent.
 
    For example, if an investor owns Class A shares of one or more of the Funds
and/or another fund managed by SM&R currently valued at $80,000 and intends to
invest $25,000 over the next thirteen months in Class A shares of the Growth
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
 
                                       26
<PAGE>
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 Funds to sell the full
amount of shares specified.
 
    WAIVER OF CLASS A AND CLASS T INITIAL SALES CHARGE FOR SPECIAL
PURCHASERS.  After receipt of written request by SM&R, Class A and Class T
shares of the Funds may be purchased by certain purchasers designated in the
Class T and Class A Prospectuses at net asset value per share without the
imposition of any sales charge.
 
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) 12% FREE AMOUNT. We waive the CDSC on redemptions pursuant to a
       systematic withdrawal plan of up to 12% of account value per year. We
       apply this 12% waiver on a per fund basis to the account value determined
       at the time you elect a systematic withdrawal plan (amounts not subject
       to a CDSC, such as appreciation and reinvested dividends, are withdrawn
       first).
 
    (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) the disability began after the shares were purchased;
 
       (b) 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;
 
       (c) the redemptions are made within one year following death or initial
           determination of disability; and
 
       (d) 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 four types
       of qualified retirement plans: IRAs, custodial accounts maintained
       pursuant to Code Section 403(b), deferred compensation plans qualified
       under Code 457 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 to the extent it does not exceed 12%
           annually of the participant's or beneficiary's account value;
 
       (b) tax-free rollovers or transfers of assets to another IRA, Section
           403(b) plan, Section 457 plan or Section 401 plan invested in Class B
           shares of one or more funds managed by SM&R;
 
       (c) tax-free returns of excess contributions or returns of excess
           deferral amounts; and
 
       (d) distributions upon the death or disability (as defined in the Code)
           of the participant or beneficiary.
 
    (4) SMALL ACCOUNTS. We waive the CDSC on redemptions by the funds of small
       accounts (Accounts with a value less than $500).
 
    (5) SM&R INVESTMENTS. We waive the CDSC on redemptions of shares owned by
       SM&R or any of its affiliates.

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 12b-1 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 Funds' 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 Fund.
 
SHAREHOLDER SERVICING AND DISTRIBUTION PLAN
 
    Each Fund 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. 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 Funds (the "12b-1 Classes").
 
    For each 12b-1 Class, 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 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
 
                                       28
<PAGE>
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 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 Class, 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 Fund.
 
    The 12b-1 Plan provides that it may not be amended with respect to any 12b-1
Class 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 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 Fund, individually,
but are binding only upon the assets and property of the relevant Fund or Funds,
as provided in the Funds' Articles of Incorporation.
 
SPECIAL PURCHASE PLANS
 
AUTOMATIC INVESTMENT PLAN AND ELECTRONIC TRANSFERS
 
    Classes A, B and C provide a convenient, voluntary method of purchasing
their shares through the "Automatic Investment Plan." Classes A, B, C, T and Y
allow for the use of the "Electronic Transfers." These plans are referred to as
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 Funds, 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 Funds 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
 
                                       29
<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.
 
    After the initial minimum investment of $100 has been met, a Plan may be
opened by indicating an intention to invest $20 or more (per individual) in the
Funds 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.
 
GROUP SYSTEMATIC INVESTMENT PLAN
 
    A Group Systematic Investment Plan is available for purchases of Class A,
Class B, or Class C shares. This Plan provides employers and employees with a
convenient means for purchasing shares of the Funds 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) 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 or more must be made into each
participant's account monthly. 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
 
    You may make exchanges without charge, between the corresponding Class of
funds managed by SM&R on terms described in the Prospectuses.
 
    You may exchange shares you own in the SM&R Investments, Inc. Primary Fund
for shares of the SM&R Investment, Inc. Money Market Fund and vice versa.
 
    You also may exchange your Class A, B, T, Y, and J shares for shares of the
Primary Fund and 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 shares and 5 years in the case of
      Class B shares), and
 
    - you meet any minimum investment requirement for the shares you wish to
      acquire.
 
    You cannot exchange Class C shares for shares of the Money Market Fund or
Primary Fund.
 
    You may exchange shares you own in the Primary Fund or Money Market Fund for
Class A, T, Y, and J shares of another fund managed by SM&R, provided you meet
any eligibility requirements and pay any sales charge applicable to the acquired
shares. You cannot exchange shares of the Money Market Fund or Primary Fund for
Class B or C shares of another fund.
 
                                       30
<PAGE>
    We waive any sales charges on Class A and Class T shares acquired through an
exchange if you previously paid a sales charge on amounts invested in those
shares. In other words, we will never impose a front-end sales charge on the
same investments twice. If the exchanged shares were acquired through
reinvestment of dividends or capital gains distributions while in a Class that
imposes a front-end sales charge, we deem those amounts invested in shares to
have previously paid a sales charge for purposes of the exchange privilege.
 
    For example, you purchase Class T shares of the Growth Fund. You then
exchange all your Class T shares (including shares acquired through reinvestment
of dividends and capital gains distributions) for shares of the Money Market
Fund. Later, you re-exchange those shares of the Money Market Fund for Class T
shares of the Equity Income Fund. We would not impose any sales charge upon re-
exchange into Class T shares because you previously paid a sales charge on those
amounts invested in shares.
 
    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 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 into which the exchange is being made.
 
REDEMPTION
 
GENERAL
 
    Any shareholder may redeem all or any part of his shares by submitting a
written request to SM&R as the Funds' 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
 
                                       31
<PAGE>
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
"Redeeming Shares" in the Prospectuses. Corporations, executors, divorced
persons, administrators, trustees or guardians will be required to submit
further documentation. Any applicable CDSC will be deducted 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." (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 Fund's
portfolio securities and the applicable CDSC, if any. 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 a Fund may be requested to redeem shares for which it has
not yet received good payment for prior purchases of Fund shares. Accordingly,
proceeds of a Fund will not be paid until good payment has been received which
could be as much as ten (10) 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.
 
    The right of redemption is subject to suspension and payment 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 a Fund of its securities is not reasonably practicable or it
is not reasonably practicable for a Fund to fairly determine the value of its
net assets; or for such other periods as the SEC has by order permitted such
suspension for the protection of a Fund's security holders.
 
    The Funds have 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 Fund at the beginning of such
period. The Funds 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.
 
SYSTEMATIC WITHDRAWAL PLAN
 
    As described in the Prospectus under "Systematic Withdrawal Plan," each Fund
has a Systematic Withdrawal Plan which allows shareholders having an account
value of $5,000 or more ($50,000 or more for Class Y) 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
Funds because of the sales charge or CDSC (as applicable) involved in additional
purchases and withdrawals. 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 Funds'
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 lst 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
 
                                       32
<PAGE>
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 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 Funds and SM&R discourage
shareholders from maintaining a withdrawal account while concurrently and
regularly purchasing shares of the Funds, although such practice is not
prohibited.
 
TAX STATUS
 
ELECTION TO BE TAXED AS A REGULATED INVESTMENT COMPANY
 
    Each Fund is a separate entity for federal income tax purposes and each Fund
has elected to be treated as a regulated investment company under Subchapter M
of the Internal Revenue Code. Each Fund 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 any Fund will be required to pay
federal income taxes.
 
    In order to qualify as a regulated investment company, each Fund 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. 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
 
                                       33
<PAGE>
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 any 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 the 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.
 
    A percentage of the dividends paid by each Fund to corporate shareholders
may in certain circumstances qualify for the dividends received deduction
available to corporations. The dividends received deduction will be available
only with respect to dividends designated by the Fund as eligible for such
treatment. Dividends so designated must be attributable to dividends earned by
the Fund from U.S. corporations and must not have been earned from investments
that were debt-financed or held by the Fund for less than the requisite period.
Similarly, the deduction may be reduced or eliminated if the investment in the
Fund by the corporate shareholder was debt-financed or held less than the
requisite period. All dividends from the Funds, including dividends eligible for
the dividends-received deduction, are included in a corporation's alternative
minimum taxable income calculation.
 
    At the end of each calendar year, the Funds 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 (as well as federal) tax laws to these distributions and redemption
proceeds received from the Fund.
 
    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 each Fund. Because the rules on exclusion of this income
are different for corporations, corporate shareholders should consult with their
corporate tax advisors about whether any of the distributions may be exempt from
corporate income or franchise taxes.
 
    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
any Fund.
 
                                       34
<PAGE>
    Shareholders are reminded that dividends are taxable whether received in
cash or reinvested and received in the form of additional shares. Furthermore,
any distribution received shortly after a purchase of shares by an investor will
have the effect of reducing the per share net asset value of his shares by the
amount of the distributions. Such distributions, although in effect a return of
capital, are subject to taxes. Furthermore, if the net asset value of each share
is reduced below the shareholder's cost as a result of a distribution, such
distribution would be a return of capital although taxed at applicable rates.
 
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 should
consult with their tax advisor concerning the tax reporting requirements in
effect on the redemption or exchange of such shares.
 
    Each Fund or the securities dealer effecting a redemption transaction is
required to file an information return (1099-B) with the IRS with respect to
each sale of Fund shares by a shareholder. The year-end statement provided to
each shareholder will serve as a substitute 1099-B for purposes of reporting any
gain or loss on the tax return filed by the shareholder. In addition, each Fund
is required by law and IRS regulations to withhold 31% of the dividends,
redemptions and other payments made to non-exempt accounts unless shareholders
have provided a corrected taxpayer identification number and made the
certifications required by the IRS as indicated in the shareholder application
when opening an account.
 
BACKUP WITHHOLDING
 
    Each Fund 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 Application.
A shareholder may also be subject to backup withholding if the IRS or a broker
notifies the Fund 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 fund.
 
                                       35
<PAGE>
THE UNDERWRITER
 
    SM&R serves as principal underwriter of the shares of the Funds pursuant to
an agreement dated May 1, 1993, as amended on November 19, 1998 (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 each Fund or by vote of a majority
of the outstanding voting securities of a Fund and, in either case, by the
specific 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
each Fund in accordance with such procedures at a meeting held on November 19,
1998. 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 a Fund, 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 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 funds managed by SM&R. 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 6.1%
to a minimum of 2.6% of the net amount invested and from a maximum of 4.75% to a
minimum of 2.0% of the public offering price. In connection with certain
purchases of Class T shares of $500,000 or more, SM&R may pay broker-dealers
from its own profits and resources, a per annum percent of the amount invested
as follows: Year 1--0.35%, Year 2--0.25%, and, in the third and subsequent
years, 0.075% per annum, in quarterly installments, to those broker-dealers with
accounts in the aggregate totaling $1 million or more. Such allowances are the
same for all broker-dealers.
 
    The aggregate amount of sales charge received by SM&R from the sale of Fund
shares for the past three fiscal years is as follows:

AUDITORS AND FINANCIAL STATEMENTS
 
    Tait, Weller & Baker, 8 Penn Center, Philadelphia, PA 19103, are the Fund's
independent auditors and perform annual audits of the Fund's financial
statements.
 
    Due to a concern over a potential conflict of interest, KPMG resigned as
auditors to the Funds. The Board appointed Tait, Weller & Baker to serve as the
independent auditors to the Funds for the year ended December 31, 1997.
Shareholders of the Funds ratified the selection of Tait, Weller & Baker for the
year ended December 31, 1998 at a meeting of the Shareholders held on May 28,
1998. For the year ended December 31, 1996, 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 1996 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 Tait, Weller & Baker and KPMG has advised the Funds that
neither it nor any present member or associate of the relevant firm has any
financial interest, direct or indirect, in any of the Funds.

CUSTODIAN
 
    The cash and securities of the Funds are held by SM&R, 2450 South Shore
Boulevard, Suite 400, League City, Texas 77573, pursuant to a Custodian
Agreement dated September 12, 1991. As custodian, SM&R will hold and administer

                                       37
<PAGE>
accounting books and records as provided for in such Custodian Agreement. The
compensation paid to the Custodian is paid by the Funds and is based upon and
varies with the number, type and amount of transactions conducted by the
Custodian.
 
    SM&R has entered into a sub-custodial agreement with Moody National Bank of
Galveston (the "Bank") effective July 1, 1991. Under the sub-custodian
agreement, the cash and securities of the Funds will be held by the Bank which

facilities of the book-entry system of the Federal Reserve Bank with respect to
securities of the Funds held by it on behalf of SM&R for the Funds.
 
COUNSEL
 
    The Fund's General Counsel is Greer, Herz & Adams, L.L.P., 18th Floor, One
Moody Plaza, Galveston, Texas 77550.
 
TRANSFER AGENT AND DIVIDEND PAYING AGENT
 
    SM&R is the transfer agent and dividend paying agent for the Funds, the
American National Investments Accounts, Inc., and SM&R Investments, Inc. (See
"Administrative Service Agreement" herein.) A discussion of SM&R's duties as
transfer agent is set forth above under "Administrative Service Agreement."
 
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 total return fluctuates 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.
 
    Each Fund's performance may be quoted in advertising in terms of 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, 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 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.
 
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
 
                                       38
<PAGE>
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.
 
    The average annual total returns for each Fund for the following periods
ended June 30, 1998 are:

- --------------------------------------------------------------------------------------------
</TABLE>
 
    The average annual total return figures for the Funds 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 ERV assumes the deduction of all nonrecurring
charges deducted at the end of each period.
 
    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.
 
CUMULATIVE TOTAL RETURN
 
    The cumulative return reflects each year's hypothetical annually compounded
return that would equate a ten thousand dollar investment on January 1, 1988 to
the redeemable value on December 31 of each of the next ten years by adding one
to the computed average annual total return multiplied by:
 
    1.  the $10,000 hypothetical investment for the first year, or
 
    2.  the redeemable value of the $10,000 investment as of December 31 of the
       preceding year for years two through ten.
 
    The total return percentage calculations assume the maximum sales charge was
deducted from the initial amount invested and that all income dividends and
capital gain distributions are reinvested on the reinvestment dates at the net
asset value.
 
                                       39
<PAGE>
    The income return percentage reflects the income dividends paid during the
year divided by:
 
    1.  the $10,000 hypothetical investment for the first year, or
 
    2.  the redeemable value of the $10,000 investment as of December 31 of the
       preceding year for years two through ten.
 
    The appreciation percentage represents the change in the net asset value
during the year less the income dividends paid during the year divided by:
 
    1.  the $10,000 hypothetical investment for the first year, or
 
    2.  the redeemable value of the $10,000 investment as of December 31 of the
       preceding year for years two through ten.
 
    The total return on the net amount invested reflects the hypothetical return
that would equate a January 1, 1988 initial ten thousand dollar investment less
the maximum $575 sales load to the redeemable value on December 31, 1988 by
adding one to the computed total return and multiplying the result by $9,425
(the initial ten thousand dollar investment less the maximum sales load).
 
MULTI-CLASS PERFORMANCE
 
    The Funds converted from a single-class to a multi-class structure. That
single class of outstanding shares was converted to Class T shares, effective
December 31, 1998. Existing shareholders of a Fund as of December 31, 1998
became shareholders in Class T of that Fund.
 
    The performance calculations for the Classes of the Funds, other than the
Class T shares, and any Classes that might later be created, may be stated so as
to include the performance of the Fund's Class T shares. For these purposes, the
inception of the Class T shares is the inception of the Funds. 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 for 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 the Funds might
satisfy their investment objective, advertisements and other materials regarding
the Funds may discuss various measures of the 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:
 
    DOW JONES COMPOSITE AVERAGE OR ITS COMPONENT AVERAGES--an unmanaged index
composed of 30 blue-chip industrial corporation stocks (Dow Jones Industrial
Average), 15 utilities company stocks (Dow Jones Utilities Average), and 20
transportation company stocks. Comparisons of performance assume reinvestment of
dividends.
 
    STANDARD & POOR'S 500 STOCK INDEX OR ITS COMPONENT INDICES--an unmanaged
index composed of 400 industrial stocks, 40 financial stocks, 40 utilities
stocks, and 20 transportation stocks. Comparisons of performance assume
reinvestment of dividends.
 
    THE NEW YORK STOCK EXCHANGE COMPOSITE OR COMPONENT INDICES--unmanaged
indices of all industrial, utilities, transportation, and finance stocks listed
on the New York Stock Exchange.
 
                                       40
<PAGE>
    WILSHIRE 5000 EQUITY INDEX--represents the return on the market value of all
common equity securities for which daily pricing is available. Comparisons of
performance assume reinvestment of dividends.
 
    LIPPER--MUTUAL FUND PERFORMANCE ANALYSIS AND LIPPER--FIXED INCOME FUND
PERFORMANCE ANALYSIS--measure total return and average current yield for the
mutual fund industry. Rank individual mutual fund performance over specified
time periods, assuming reinvestment of all distributions, exclusive of any
applicable sales charges.

analyzes price, current yield, risk, total return, and average rate of return
(average annual compounded growth rate) over specified time periods for the
mutual fund industry.
 
    MUTUAL FUND SOURCE BOOK, PUBLISHED BY MORNINGSTAR, INC.--analyzes price,
yield, risk and total return for equity funds.
 
    FINANCIAL PUBLICATIONS: THE WALL STREET JOURNAL AND BUSINESS WEEK, CHANGING
TIMES, FINANCIAL WORLD, FORBES, FORTUNE, AND MONEY MAGAZINES provide performance
statistics over specified time periods.
 
    CONSUMER PRICE INDEX (OR COST OF LIVING INDEX), PUBLISHED BY THE U.S. BUREAU
OF LABOR STATISTICS--a statistical measure of change, over time, in the price of
goods and services in major expenditure groups.
 
    SALOMON BROTHERS BROAD BOND INDEX OR ITS COMPONENT INDICES--The Aggregate
Bond Index measures yield, price and total return for Treasury, Agency,
Corporate, Mortgage, and Yankee bonds.
 
    STANDARD & POOR'S BOND INDICES--measures yield and price of Corporate,
Municipal, and Government bonds.
 
    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 the Funds, 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 the Funds to calculate its
figures. In addition there can be no assurance that the Funds will continue this
performance as compared to such other averages.

NOTES TO FINANCIAL STATEMENTS  June 30, 1998  (Unaudited)
- --------------------------------------------------------------------------------
AMERICAN NATIONAL FUNDS GROUP
 
NOTE 1--SIGNIFICANT ACCOUNTING POLICIES
The American National Funds Group (the "Funds") are diversified open-end
management investment companies registered under the Investment Company Act of
1940, as amended. The Funds are comprised of the American National Growth Fund,
Inc., American National Income Fund, Inc. and the Triflex Fund, Inc. The
following is a summary of significant accounting policies consistently followed
by the Funds in the preparation of its financial statements. The preparation of
financial statements in conformity with generally accepted accounting principles
requires management to make estimates and assumptions that affect the reported
amounts of assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.
 
INVESTMENT VALUATION:
Investments listed on national exchanges are valued at the last sales price of
the day, or if there were no sales, then at the last bid price. 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 for which market quotations are not readily
available are valued at fair value as determined by the Board of Directors.
Commercial paper is stated at amortized cost, which is equivalent to fair value.
 
INVESTMENT TRANSACTIONS AND RELATED INVESTMENT INCOME:
Investment transactions are accounted for on the trade date (date order to buy
or sell is executed). Divided income is recognized on the ex-dividend date, and
interest income is recognized on an accrual basis. Realized gains and losses
from security transactions are reported on the basis of specific identification
for financial reporting and federal income tax purposes.
 
FEDERAL INCOME TAXES:
For federal income tax purposes, each fund is treated as a separate entity. The
Funds intend to comply with requirements of the Internal Revenue Code relating
to regulated investment companies and intend to distribute substantially all of
its taxable income to its shareholders. Therefore, no provision for federal
income taxes is recorded in the accompanying financial statements.
 
CAPITAL STOCK TRANSACTIONS AND DISTRIBUTIONS TO SHAREHOLDERS:
Fund shares are sold in a continuous public offering at net asset value plus a
sales charge. The Funds repurchase shares at net asset value. Dividends and
other distributions are recorded by the Fund on the ex-dividend date and may be
reinvested at the net asset value.
 
EXPENSES:
Operating expenses not directly attributable to a Fund's operations are prorated
among the Funds based on the relative net assets or shareholders of each Fund.
 
NOTE 2--INVESTMENT ADVISORY AND SERVICE FEES AND OTHER TRANSACTIONS WITH
AFFILIATES
Securities Management and Research, Inc. ("SM&R") is the investment advisor and
principal underwriter for the Funds. Investment advisory fees paid to SM&R are
computed as a percentage of the average daily net assets as follows:

INDEPENDENT AUDITORS' REPORT
 
The Board of Directors and Shareholders
American National Funds Group
 
    We have audited the accompanying statements of assets and liabilities of
American National Funds Group (comprised of American National Growth Fund, Inc.,
American National Income Fund, Inc. and Triflex Fund, Inc.), including the
schedule of investments as of December 31, 1997, the related statements of
operations, the statements of changes in net assets and the financial highlights
for the year then ended. These financial statements and financial highlights are
the responsibility of the Fund's management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits. The statements of changes for the year ended December 31, 1996 and the
financial highlights for each of the four years in the period ended December 31,
1996 were audited by other auditors whose report dated February 7, 1997 issued
an unqualified opinion.
 
    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Our procedures included confirmation of securities owned as of
December 31, 1997, by correspondence with the custodian. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
    In our opinion, the financial statements and financial highlights referred
to above present fairly, in all material respects, the financial position of
American National Funds Group as of December 31, 1997, the results of its
operations, the changes in its net assets and the financial highlights for the
year then ended in conformity with generally accepted accounting principles.

NOTES TO FINANCIAL STATEMENTS  June 30, 1998  (Unaudited)
- --------------------------------------------------------------------------------
AMERICAN NATIONAL FUNDS GROUP
 
NOTE 1--SIGNIFICANT ACCOUNTING POLICIES
The American National Funds Group (the "Funds") are diversified open-end
management investment companies registered under the Investment Company Act of
1940, as amended. The Funds are comprised of the American National Growth Fund,
Inc., American National Income Fund, Inc. and the Triflex Fund, Inc. The
following is a summary of significant accounting policies consistently followed
by the Funds in the preparation of its financial statements. The preparation of
financial statements in conformity with generally accepted accounting principles
requires management to make estimates and assumptions that affect the reported
amounts of assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.
 
INVESTMENT VALUATION:
Investments listed on national exchanges are valued at the last sales price of
the day, or if there were no sales, then at the last bid price. 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 for which market quotations are not readily
available are valued at fair value as determined by the Board of Directors.
Commercial paper is stated at amortized cost, which is equivalent to fair value.
 
INVESTMENT TRANSACTIONS AND RELATED INVESTMENT INCOME:
Investment transactions are accounted for on the trade date (date order to buy
or sell is executed). Dividend income is recognized on the ex-dividend date, and
interest income is recognized on an accrual basis. Realized gains and losses
from security transactions are reported on the basis of specific identification
for financial reporting and federal income tax purposes.
 
FEDERAL INCOME TAXES:
For federal income tax purposes, each fund is treated as a separate entity. The
Funds intend to comply with requirements of the Internal Revenue Code relating
to regulated investment companies and intend to distribute substantially all of
its taxable income to its shareholders. Therefore, no provision for federal
income taxes is recorded in the accompanying financial statements.
 
CAPITAL STOCK TRANSACTIONS AND DISTRIBUTIONS TO SHAREHOLDERS:
Fund shares are sold in a continuous public offering at net asset value plus a
sales charge. The Funds repurchase shares at net asset value. Dividends and
other distributions are recorded by the Fund on the ex-dividend date and may be
reinvested at the net asset value.
 
EXPENSES:
Operating expenses not directly attributable to a Fund's operations are prorated
among the Funds based on the relative net assets or shareholders of each Fund.
 
NOTE 2--INVESTMENT ADVISORY AND SERVICE FEES AND OTHER TRANSACTIONS WITH
AFFILIATES
Securities Management and Research, Inc. ("SM&R") is the investment advisor and
principal underwriter for the Funds. Investment advisory fees paid to SM&R are
computed as a percentage of the average daily net assets as follows:

</TABLE>
 
The investment advisory agreement for the Growth Fund provides for incentive
fees that will increase or decrease the basic investment advisory fee, based on
the performance of the fund in relation to a specified industry index for the
funds with similar objectives over a rolling 36-month period. For the period
ended June 30, 1998 the investment advisory fee was decreased by approximately
$184,400.
 
SM&R has agreed to reimburse the Funds for all expenses, other than taxes,
interest, and expenses directly related to the purchase and sale of investment
securities, in excess of 1.25% per annum of the average daily net assets.
