                INVESTMENT OBJECTIVES AND POLICIES OF THE FUNDS
 
INVESTMENT OBJECTIVES
Each Fund of the Investment Company has a different investment objective which
it pursues through separate investment policies as described below. The
differences in objectives and policies among the Funds can be expected to
affect the return
 
                                       5
<PAGE>
 
of each Fund and the degree of market and financial risk to which each Fund is
subject. As used in the following discussion, "market risk" refers to the
volatility of the reaction of the price of the security to changes in
conditions in the securities markets in general and, with particular reference
to debt securities, changes in the overall level of interest rates; "financial
risk" refers to the ability of an issuer of a debt security to pay principal
and interest on that security and to the earning stability and overall
financial soundness of an issuer of an equity security; and "current income
volatility" refers to the degree and rapidity with which changes in the
overall level of interest rates become reflected in the level of current
income of a Fund. The investment objectives of each Fund may not be changed
without the approval of the holders of a majority of the outstanding shares of
each Fund affected. There can be no assurance that the objectives of any of
the Funds will be met. Investments in the Money Market Fund (and in the other
Funds of the Investment Company) are neither insured nor guaranteed by the
U.S. Government. The investment objectives and policies of each Fund are
discussed below.
 
THE MONEY MARKET FUND
The investment objective of the Money Market Fund is the realization of high
current income to the extent consistent with the maintenance of liquidity,
investment quality and stability of capital. The Fund will invest only in
money market instruments and other short-term debt securities.
 
Specifically, the Money Market Fund will invest only in the following kinds of
money market instruments, payable in United States dollars: (1) securities
issued or guaranteed by the United States Government or one of its agencies or
instrumentalities ("government securities"); (2) negotiable certificates of
deposit, bank time deposits, bankers' acceptances and other short-term debt
obligations of domestic banks and foreign branches of domestic banks and U.S.
branches of foreign banks (see "Investment Objectives and Policies of the
Funds--Other Portfolio Strategies--Foreign Securities"), which at the time of
their most recent annual financial statements show assets in excess of $1
billion; (3) certificates of deposit, time deposits and other short-term debt
obligations of domestic savings and loan associations, which at the time of
their most recent annual financial statements show assets in excess of $1
billion; (4) repurchase agreements covering government securities,
certificates of deposit, commercial paper or bankers' acceptances; (5)
commercial paper; (6) variable amount floating rate notes; and (7) debt
securities issued by a corporation. These instruments are more fully described
in the Statement of Additional Information.
 
For purposes of the Money Market Fund's investment policy only, "money market
instruments and other short-term debt securities" shall mean securities having
a remaining maturity of up to 13 months (25 months in the case of government
securities). The dollar-weighted average maturity of the securities held by
the Money Market Fund will not exceed 90 days.
 
The Money Market Fund may also enter into transactions in options, futures
contracts and options on futures, contracts on United States Treasury
securities and Eurodollar deposits. Such transactions and instruments are more
fully described below and in the Statement of Additional Information.
 
All of the securities held by the Money Market Fund will have received (or be
of comparable quality to securities which have received), at the time of the
purchase, a rating in one of the two highest categories by any two nationally
recognized statistical rating agencies and at least 95% of the securities held
by the Money Market Fund will have received (or be of comparable quality to
securities which have received), at the time of purchase, the highest rating
by any two such rating agencies. (The Board of Directors of the Investment
Company must approve or ratify the purchase of any security (other than any
government security) which has received no rating or which has been rated by
only one rating agency.) Securities which are subsequently downgraded below
the two highest categories will be disposed of as soon as practicable absent a
finding by the Board of Directors that this would not be in the best interests
of the Fund.
 
The Money Market Fund will not invest more than 5% of its total assets in
securities of, or subject to puts from, any one issuer (other than government
securities and repurchase agreements fully collateralized by government
securities) provided that (x) the Fund may invest up to 10% of its total
assets in securities issued or guaranteed by a single issuer with respect to
which the Fund has an unconditional put and (y) with respect to 25% of its
total assets the Fund may, with respect to securities meeting the highest
investment criteria, exceed the 5% limit for up to three business days.
 
The Money Market Fund should be subject to relatively little market or
financial risk but a relatively high level of current income volatility.
 
THE ALL AMERICA FUND
The investment objective for approximately 60% of the assets of the All
America Fund (the "Indexed Assets") is to provide investment results that to
the extent practical correspond to the price and yield performance of publicly
traded common stocks in the aggregate, as represented by the Standard & Poor's
Composite Index of 500 Stocks (the "S&P 500 Index"). The Indexed Assets will
be invested in the same manner as the Equity Index Fund. See "The Equity Index
Fund" below.
 
 
                                       6
<PAGE>
 
The investment objective for the remaining approximately 40% of the assets
(the "Active Assets") is to achieve a high level of total return, through both
appreciation of capital and, to a lesser extent, current income, by means of a
diversified portfolio of securities that may include common stocks, securities
convertible into common stocks, bonds and money market instruments. The Active
Assets will be invested by three subadvisers (each a "Subadviser", and
together the "Subadvisers"), under a subadvisory agreement (each a
"Subadvisory Agreement") between the Adviser and each of the Subadvisers, and
the Adviser. The Adviser will allocate the Active Assets to maintain, to the
extent practicable under current market conditions, approximately equal
amounts with the Subadvisers and the Adviser. The Subadvisers are Palley-
Needelman Asset Management, Inc. ("Palley-Needelman"), Oak Associates, Ltd.
and Fred Alger Management, Inc. ("Alger Management"). See "Investment Advisory
Arrangements--The Subadvisers".
 
Palley-Needelman will invest its portion of Active Assets in stocks that
Palley-Needelman considers to be of high quality with lower than average price
volatility and low price/earning ratios. Companies generally will have below
market debt levels, earnings growth of 10% or more, current yield of 3% or
more and market capitalization of $500 million or more. No more than 10% of
the Palley-Needelman portion may be invested in any one industry and no more
than 20% may be invested in American Depositary Receipts ("ADRs"). Oak
Associates will invest in mid-sized capitalization stocks that have low
current income and the potential for significant growth. Oak Associates
monitors 400 stocks and will invest its portion of the Fund in approximately
25 common stocks without regard for market industry weighting. Alger
Management will invest in stocks with capitalization generally below $1
billion, which Alger Management considers to be fundamentally sound with the
potential for strong growth and for earnings in excess of market expectations.
Except during temporary defensive periods, at least 85% of the Alger
Management portion will be invested in equity securities. The Adviser
generally will invest in stocks that it considers undervalued. Its approach is
to identify companies with strong financials, substantial cash flow,
conservative accounting, usually low debt-to-equity ratios and average market
capitalization generally below $1 billion. Some of the companies whose stocks
are purchased by Oak Associates, or by the Adviser for its portion of the
Active Assets, may have limited Wall Street coverage and low institutional
ownership.
 
Each of the Subadvisers and the Adviser will seek to achieve the investment
objective of the Active Assets by investing in such securities that, based on
certain fundamental and/or technical standards of selection, it determines
offer attractive opportunities for total return through capital appreciation
and, to a lesser degree, income. The Investment Company believes that the
combination of the Indexed Assets and the Active Assets will provide a
reasonable opportunity for the Fund to outperform the S&P 500 Index by
providing a diversified portfolio of Active Assets with diversified management
and a broad exposure to the market.
 
Assets in the All America Fund will be rebalanced periodically to retain the
approximate 60%/40% relationship between Indexed Assets and Active Assets. The
Adviser may manage cash allocated to the Active Assets prior to investment in
securities by the Subadvisers.
 
THE EQUITY INDEX FUND
The investment objective of the Equity Index Fund is to provide investment
results that to the extent practical correspond to the price and yield
performance of publicly traded common stocks in the aggregate, as represented
by the S&P 500 Index.
 
The Equity Index Fund will attempt to duplicate the investment results of the
S&P 500 Index, which is composed of 500 selected common stocks, most of which
are listed on the New York Stock Exchange. Standard & Poor's Corporation
chooses the stocks to be included in the S&P 500 Index solely on a statistical
basis. The inclusion of a stock in the S&P 500 Index does not imply an opinion
by Standard & Poor's Corporation that the stock is an attractive investment.
An investment in the Fund involves risks similar to those of investing in
common stocks. The Fund will attempt to be fully invested at all times in the
stocks that comprise the S&P 500 Index and at least 80% of the Fund's net
assets will be so invested.
 
The weightings of stocks in the S&P 500 Index are based on each stock's
relative total market capitalization; that is, its market price per share
times the number of shares outstanding. Stocks will be selected for the Fund's
portfolio in the order of their weightings in the S&P 500 Index beginning with
the heaviest weighted stocks. The percentage of the Fund's assets invested in
each of the selected stocks will be approximately the same as the percentage
the stock represents in the S&P 500 Index.
 
The Fund will be managed using a computer program to determine which stocks
are to be purchased or sold to replicate the S&P 500 Index to the extent
feasible. Initially the Fund contemplates executing all transactions through a
single broker. From time to time, administrative adjustments may be made in
the Fund's portfolio because of changes in the composition of the S&P 500
Index, but such changes should be infrequent.
 
The Fund believes that the indexing approach described above is an effective
method of substantially duplicating percentage changes in the S&P 500 Index.
It is a reasonable expectation that there will be a close correlation between
the Fund's
 
                                       7
<PAGE>
 
performance and that of the S&P 500 Index in both rising and falling markets.
The Fund will attempt to achieve a correlation between the performance of its
portfolio and that of the S&P 500 Index of at least 0.95, without taking into
account expenses. A correlation of 1.00 would indicate perfect correlation,
which would be achieved when the Fund's net asset value, including the value
of its dividend and capital gains distributions, increases or decreases in
exact proportion to changes in the S&P 500 Index. The Fund will invest in
stock index futures contracts, options on stock indices, options on stock
index future contracts, puts and calls to the extent necessary to attempt to
achieve this correlation. The Fund's ability to correlate its performance with
the S&P 500 Index, however, may be affected by, among other things, changes in
securities markets, the manner in which the S&P 500 Index is calculated by
Standard & Poor's Corporation and the timing of purchases and redemptions. In
the future, the Board of Directors, subject to the approval of shareholders,
may select another index if such a standard of comparison is deemed to be more
representative of the performance of common stocks in general.
 
The Fund's ability to duplicate the performance of the S&P 500 Index also
depends to some extent on the size of the Fund's portfolio and the size of
cash flows into and out of the Fund. Investment changes to accommodate these
cash flows are made to maintain the similarity of the Fund's portfolio to the
S&P 500 Index to the maximum practicable extent. Mutual of America Life
invested $25 million in the Fund on February 5, 1993 and will endeavor to
maintain a minimum asset balance in the Fund (including its investments and
the investments of participants and contractholders) which is at least $25
million at any time, but does not guarantee to do so. As participants and
contractholders invest in the Fund through Separate Accounts, over time Mutual
of America Life reserves the right to reduce its investment in the Fund
consistent with the above Fund target minimum balance.
 
THE BOND FUND, THE SHORT-TERM BOND FUND AND THE MID-TERM BOND FUND
The three Bond Funds (the Bond Fund, the Short-Term Bond Fund and the Mid-Term
Bond Fund (sometimes collectively referred to as the "Bond Funds" or
singularly as "any" or "each" Bond Fund)) will have the same investment
objectives as described below, but will seek to achieve those objectives
through different policies representing the average maturity of the securities
held in their respective portfolios, as follows:
 
The Bond Fund will consist of debt securities with average maturities which
will vary according to market conditions and the stage of the interest rate
cycle.
 
The Short-Term Bond Fund will consist of debt securities which will produce a
portfolio with an average maturity of one to three years.
 
The Mid-Term Bond Fund will consist of debt securities which will produce a
portfolio with an average maturity of three to seven years.
 
When interest rates go up, the market value of outstanding debt securities
declines and vice versa. In recent years the volatility of the market for debt
securities has increased significantly and the market value of longer-term
obligations has been subject to wide fluctuations, particularly as contrasted
with short-term instruments. The Bond Funds may realize income to the extent
such realizations are considered advantageous in light of existing market
conditions. The annual rate of portfolio turnover of the Bond Funds is not
expected to average in excess of 200%. A high level of portfolio turnover will
result in an increase in transaction costs and may adversely affect the tax
status of the Investment Company. See "Dividends, Distributions and Taxes."
 
The primary investment objective of the Bond Funds is to provide as high a
level of current income over time as is believed to be consistent with prudent
investment risk. A secondary objective is preservation of shareholders'
capital. The Bond Funds seek to realize these objectives through careful
selection and, when appropriate, active trading of bonds and other
investments. The assets of the Bond Funds will consist primarily of publicly
traded debt securities, such as bonds, notes, debentures and equipment trust
certificates. Such securities may carry certain equity features, such as
conversion of exchange rights, or warrants for the acquisition of stocks of
the same or different issuers, or participations based on revenues, sales or
profits.
 
It is contemplated that at least 80% of each Bond Fund's assets will consist
of (a) domestic debt securities that have at the time of purchase a rating of
at least Baa3 as determined by Moody's Investors Services, Inc. or BBB- as
determined by Standard & Poor's Corporation or equivalent ratings of a similar
nationally recognized rating service; (b) securities issued or guaranteed by
the United States Government or its agencies or instrumentalities; (c) cash or
cash equivalents; and (d) the types of money market instruments in which the
Money Market Fund may invest. These instruments should be subject to little
financial risk, to moderately high levels of market risk and to moderate
current income volatility. The remaining assets of the Bond Funds may be
invested in (1) other securities that are unrated or rated lower than Baa3 or
BBB-, which are sometimes referred to as high yield/high risk securities, (2)
Canadian and other foreign securities and (3) securities issued in foreign
markets by domestic issuers or their overseas subsidiaries if guaranteed by
the parent. Unrated securities or securities
 
                                       8
<PAGE>
 
rated lower than Baa3 or BBB- may be subject to greater market and financial
risk than higher quality securities, and it is not currently contemplated that
more than 5% of any Bond Fund's assets will consist of these securities. The
instruments described in this paragraph are more fully described in the
Statement of Additional Information.
 
The market value of fixed-income debt securities is affected by changes in
general market interest rates. If interest rates fall, the market value of
fixed-income securities tends to rise; however, if interest rates rise, the
value of fixed-income securities tends to fall. This market risk affects all
fixed income securities, but lower rated and unrated securities may be subject
to a greater market risk than higher rated (lower yield) securities.
 
Lower rated and unrated securities are also generally subject to greater
financial risk than higher rated securities. Since lower rated and unrated
securities are generally issued by corporations that are not as creditworthy
or financially secure as issuers of higher rated securities, there is a
greater risk that issuers of lower rated (higher yield) securities will not be
able to pay the principal and interest due on such securities, especially
during periods of adverse economic conditions. Risk factors related to
investments in lower rated and unrated securities are more fully described in
the Statement of Additional Information.
 
Each of the Bond Funds generally will not acquire securities of companies in
any one industry if, immediately after giving effect to any such acquisition,
more than 25% of the value of its total assets would be invested in such
industry. A Fund would, however, invest more than 25% (but not more than 75%)
of its assets in the electric, gas and/or telephone utility industries
whenever it is determined that the spread between the yields on such industry
securities and Treasury notes and/or bonds is historically high and that
obligations having comparable maturity, yield and quality of issuers in other
industries are not available; provided, however, that in no event will any
Bond Fund invest more than 75% of the value of its total assets in all those
industries. No one "aspect" of the electric, gas or telephone utility
industries will be emphasized.
 
Investment in companies in these industries involves the risk of unfavorable
action, from an investment viewpoint, by their regulatory authorities.
Concentration in any or all of such industries may increase the investment
risk as a result of adverse circumstances which could affect all companies in
a particular industry simultaneously. In addition, debt securities in
electric, gas and telephone industries tend to have longer maturities than
those of industrial issuers, and unlike industrial debt issues, do not
typically require partial repayment of the principal through a sinking fund
during the life of the securities. As a result, electric, gas and telephone
issues may show more price volatility in periods of changing interest rates
than would industrial issues of like quality. The electric, gas and telephone
utility industries are subject to extensive government regulation as to rates
and services.
 
The Bond Funds will not directly purchase common stocks. However, a Fund may
have up to 10% of the value of its total assets invested in stocks acquired
either by conversion of fixed-income securities or by the exercise of warrants
attached thereto.
 
The Bond Funds may also enter into transactions in exchange-traded options,
futures contracts and options on futures contracts on United States Treasury
securities and Government National Mortgage Association ("GNMA") Securities.
To be included in any of the Bond Funds, options and futures must be traded on
a domestic exchange.
 
THE COMPOSITE FUND
The investment objective of the Composite Fund is to achieve as high a total
rate of return, through both appreciation of capital and current income, as is
consistent with prudent investment risk by means of a diversified portfolio of
publicly traded common stocks, publicly traded debt securities and money
market instruments. The Fund will seek to achieve long-term growth of its
capital and increasing income by investments in common stocks and other
equity-type securities and a high level of current income through investments
in publicly traded debt securities and money market instruments. It is
anticipated that the portion of the assets invested in each type of security
will vary, at the Investment Company's discretion, in accordance with economic
conditions, the general level of common stock prices, interest rates and other
relevant consideration, including the risks associated with each investment
medium. No more than 75% of the value of the Fund's assets, however, may be
invested in either common stock and other equity-type securities, or in debt
securities with a remaining maturity of more than one year. Up to 100% of the
Fund's assets may be invested in money market instruments. The equity
securities invested in by the Fund will consist of the types of equity
securities in which the Active Assets of the All America Fund may be invested.
The publicly traded debt securities will consist of the types of securities in
which any Bond Fund may invest. The money market instruments will consist of
the types of securities in which the Money Market Fund may invest. The
Composite Fund may also engage in the same type of transactions in options,
futures contracts and options on futures contracts as the Stock, Bond, Short-
Term Bond, Mid-Term Bond and Money Market Funds. The Composite Fund will be
subject to varying levels of market and financial risk and current income
volatility, depending upon the "mix" of instruments in which the Fund is from
time to time invested. The Composite Fund will not invest in debt securities
rated below investment grade. Securities which are subsequently downgraded may
continue to be held and will be sold only if, in the judgment of the
Investment Adviser, it is advantageous to do so.

THE AGGRESSIVE EQUITY FUND
The Aggressive Equity Fund will be divided by the Adviser into two segments so
as to utilize two investment styles.
 
The investment objective for approximately 50% of the assets of the Fund (the
"Aggressive Growth Portfolio") is to achieve capital appreciation by investing
in companies believed to possess above-average growth potential. Growth can be
in the areas of earnings or gross sales, measured in either dollars or in unit
volume. Growth potential is often sought in smaller, less well-known companies
in new and emerging areas of the economy, but may also be found in larger
companies in mature or declining industries that have been revitalized and
hold a strong industry or market position. The Aggressive Growth Portfolio
also may make investments based on prospective economic or political changes
and may invest in special situations such as corporate restructurings. The
Aggressive Growth Portfolio will invest in a relatively small number of
stocks, usually between 25 and 35 at any time, issued by leading companies in
the strong sectors of the economy.
 
The investment objective for the other approximately 50% of the assets of the
Fund (the "Aggressive Value Portfolio") is to achieve capital appreciation by
investing in companies believed to possess valuable assets or whose securities
are undervalued in the marketplace in relation to factors such as the
company's assets, earnings, or growth potential. Such companies will generally
have one or more of the following attributes: (1) valuable fixed assets, such
as complex plant and equipment that has a high replacement cost, real estate
with a current value substantially in excess of book value or large reserves
of exploitable natural resources; or (2) valuable consumer or commercial
franchises, such as well recognized trademarks or product names or potentially
valuable transportation routes. The Aggressive Value Portfolio generally
invests in small to medium capitalization securities which have low prices in
relation to cash flow, profits, sales, book value and real net asset value.
 
The Fund invests primarily in stocks, but it also may purchase convertible
securities and debt obligations that may produce capital appreciation.
Securities that meet the Fund's criteria may not be popular during certain
market cycles. The Fund can also make substantial temporary investments in
investment-grade debt securities when it believes market conditions warrant.
 
INVESTMENT RESTRICTIONS
The Investment Company has adopted a number of restrictions and policies
relating to the investment of its assets and its activities which are
fundamental policies and may not be changed without the approval of the
holders of the Investment Company's outstanding voting securities (including a
majority of the shares of each Fund). None of the Funds will: (1) with respect
to at least 75% of the value of its total assets invest more than 5% of its
total assets in the securities of any one issuer (including repurchase
agreements with any one bank), other than securities issued or guaranteed by
the United States Government or its agencies or instrumentalities (see "The
Money Market Fund" for more restrictive policies relating to that fund); (2)
with respect to at least 75% of the value of its total assets, purchase more
than 10% of the outstanding voting securities of an issuer, except that such
restriction shall not apply to securities issued or guaranteed by the United
States Government or its agencies or instrumentalities; (3) make an investment
in an industry if that investment would make the Fund's holding in that
industry exceed 25% of the Fund's total assets except for each of the Bond
Funds, which may invest up to 75% of its total assets in the electric, gas
and/or telephone utilities industries (other than investments by the Money
Market Fund in obligations issued or guaranteed by the United States
Government, its agencies or instrumentalities, certificates of deposit, or
securities issued or guaranteed by domestic branches of domestic banks and
savings and loan associations); or (4) invest more than 10% of its total
assets in repurchase agreements or time deposits maturing in more than seven
days or in portfolio securities not readily marketable. Investors are referred
to the Statement of Additional Information for a complete description of such
restrictions and policies.
 
OTHER PORTFOLIO STRATEGIES
 
Lending of Securities
A Fund may lend its securities (but not in excess of 30% of its total assets)
to brokers, dealers and financial institutions and receive as collateral cash,
securities issued or guaranteed by the United States Government or its
agencies or instrumentalities, or letters of credit of certain banks selected
by the investment adviser, which at all times while the loan is outstanding
will be maintained in amounts equal to at least 100% of the current market
value of the loaned securities. The Fund will continue to receive interest or
dividends on the securities lent, and in addition will receive a portion of
the income generated by the short-term investment of cash received as
collateral, or, alternatively, where securities or a letter of credit are used
as collateral, a lending fee paid directly to the Fund by the borrower of the
securities. Such loans will be terminable by the Fund at any time and will not
be made to affiliates of the Fund. The Fund will have the right to regain
record ownership of loaned securities in order to exercise beneficial rights,
such as voting rights or subscription rights. The Fund may pay reasonable fees
to persons unaffiliated with the Fund for services or for arranging such
loans. Loans of securities will be made only to firms that the Investment
Adviser deems creditworthy. As with an extension of credit, however, there
 
                                      10
<PAGE>
 
are risks of delay in recovery and even loss of rights in the collateral,
should the borrower of securities default, become the subject of bankruptcy
proceedings or otherwise be unable to fulfill its obligations or fail
financially.
 
Repurchase Agreements
Repurchase Agreements are more fully described in the Statement of Additional
Information. If a seller of a repurchase agreement defaults and does not
repurchase the security subject to the agreement, the Fund would look to the
collateral security underlying the sellers' repurchase agreement, including
the securities subject to the repurchase agreement, for satisfaction of the
seller's obligation to the Fund; in such event the Fund might incur
disposition costs in liquidating the collateral and might suffer a loss if the
value of the collateral declines. In addition, there is a risk that, if the
issuer of the repurchase agreement becomes involved in bankruptcy proceedings,
the Fund might be delayed or prevented from liquidating the underlying
security or otherwise obtaining it for its own purposes.
 
Options and Futures
As noted, the Funds may enter into transactions in options, futures contracts
and options on futures contracts on the types of instruments identified above.
Such transactions will be used for hedging purposes only, and not for
speculation, and could include (1) the selling of call option contracts on
portfolio securities (covered calls), and the buying of call option contracts
on such securities to close out a position acquired through the sale of such
options; (2) the buying of put option contracts on securities owned by a Fund,
and the selling of put option contracts on securities owned by a Fund to close
out a position acquired through the purchase of such options; (3) purchases
and sales of futures contracts, and purchases of options on futures contracts,
on fixed-income securities; and (4) purchases and sales of futures contracts,
and purchases of options on futures contracts, on indexes of securities. If a
hedging transaction in any such instrument is successful, a Fund's losses on
portfolio securities, or the increased cost of securities to be acquired,
should be offset, in whole or part, by corresponding gains on the hedging
position. The Funds will only enter into transactions in options, futures and
options on futures which are traded on securities or commodities exchanges
located in the United States.
 
A risk in all such transactions is a possible lack of liquidity, which could
make it difficult or impossible to close out existing positions and realize
gains or limit losses. The liquidity of a secondary market in futures
contracts or options on futures contracts may be adversely affected by "daily
price fluctuation limits," established by the exchanges on which such
instruments are traded, which limit the amount of fluctuation in the price of
a contract during a single trading day. Once the limit in a particular
contract has been reached, no further trading in such contract may occur
beyond such limit, thus preventing the liquidation of positions, and requiring
traders to make additional variation margin payments. Market liquidity in
options, futures contracts or options on futures contracts may also be
adversely affected by trading halts, suspensions, exchange or clearing house
equipment failures, government intervention, insolvency of a brokerage firm or
clearing house or other disruptions of normal trading activity.
 
The Funds are also subject to the risk of imperfect correlation between
securities held in their portfolios and the security or securities underlying
options, futures contracts or options on futures contracts traded. In the case
of options, futures contracts or options on futures based on an index of
securities, a Fund's portfolio will not duplicate the composition of the index
and, in the case of options, futures contracts and options on futures
contracts on fixed income securities, the portfolio securities being hedged
may not be the same as the securities underlying such instruments.
Consequently, the Funds bear the risk that the price of the portfolio
securities being hedged will not move in the same amount or direction as the
underlying index or obligation.
 
A Fund may sell futures contracts on fixed-income securities in anticipation
of a rise in interest rates, which would cause a decline in the value of
fixed-income securities held in the Fund's portfolio. Similarly, a Fund may
sell stock index futures contracts in anticipation of a general market wide
decline which would reduce the value of its portfolio of stocks. In either
case, if the expected decrease in the value of portfolio securities occurs,
the reduction in net asset value may be offset, in whole or in part, by
corresponding gains on the futures position. Conversely, where a Fund projects
an increase in the cost of fixed-income securities or stocks to be acquired in
the future, the Fund may purchase futures contracts on fixed-income securities
or stock indexes. If the hedging transaction is successful, the increased cost
of securities subsequently acquired should be offset, in whole or in part, by
gains on the futures position.
 
A Fund may also, instead of purchasing or selling futures contracts, purchase
call or put options on futures contracts in order to protect against declines
in the value of portfolio securities or against increases in the cost of
securities to be acquired. Purchases of options on futures contracts may
present less risk in hedging a portfolio than the purchase and sale of the
underlying futures contracts, since the potential loss is limited to the
amount of the premium paid for the option, plus related transaction costs. As
in the case of purchases and sales of futures contracts, a Fund may be able to
offset declines in the value of portfolio securities, or increases in the cost
of securities acquired, through gains realized on its purchases of options on
futures.
 
                                      11
<PAGE>
 
The Funds may also purchase put options on securities or stock indexes for the
same types of hedging purposes. The purchase of a put option on a security or
stock index permits a Fund to protect against declines in the value of the
underlying security or securities in a manner similar to the sale of futures
contracts. The maximum risk assumed by a Fund in purchasing an option is the
amount of the premium plus related transaction costs, although this entire
amount may be lost.
 
In addition, the Funds may write call options on portfolio securities or on
stock indexes for the purpose of increasing their returns and/or to protect
the value of their portfolios. In particular, where a Fund writes an option
which expires unexercised or is closed out by the Fund at a profit, it will
retain the premium paid for the option, less related transaction costs, which
will increase its gross income and will offset in part the reduced value of a
portfolio security in connection with which the option may have been written.
In contrast, however, if the price of the security underlying the option moves
adversely to the Fund's position, the option may be exercised and the Fund
will be required to sell the security at a disadvantageous price, resulting in
losses which may be only partially offset by the amount of the premium. A call
option on a security written by a Fund will be covered through ownership of
the security underlying the option or through ownership of an absolute and
immediate right to acquire such security upon conversion or exchange of other
securities held in its portfolio.
 
The Funds' hedging transactions and options on futures present certain other
risk factors which are described in the Statement of Additional Information.
 
Foreign Securities and ADRs
In addition to investing in domestic securities, the Funds may also invest in
securities of foreign issuers (including such securities traded outside the
U.S.). None of the Funds will, however, trade in foreign exchange or invest in
securities of foreign issuers, if at the time of acquisition more than 20% of
its total assets, taken at market value at the time of investment, would be
invested in such securities. Because investments in foreign securities,
particularly those of non-governmental issuers, involve considerations which
are not ordinarily associated with investing in domestic issuers, the
Investment Company will consider these special factors before investing in
foreign securities. These considerations include changes in currency rates,
currency exchange control regulations, the possibility of expropriation, the
unavailability of financial information or the difficulty of interpreting
financial information prepared under foreign accounting standards, less
liquidity and more volatility in foreign securities markets, the impact of
political, social or diplomatic developments and the difficulty of assessing
economic trends in foreign countries. If it should become necessary, the Funds
could encounter greater difficulties in involving legal processes abroad than
would be encountered in the United States. In addition, transaction costs in
foreign securities may be higher. The Investment Company will not invest in
foreign securities unless, in its opinion, such investments will meet the
standard and objectives of a particular Fund. No Fund may concentrate its
investments in any particular foreign country except Canada. Foreign issues
guaranteed by domestic corporations are considered to be domestic securities.
 
ADRs are dollar-denominated receipts issued generally by domestic banks and
representing the deposit with the bank of a security of a foreign issuer. ADRs
are publicly traded on exchanges or over-the-counter in the United States.
ADRs are not subject to the percentage limitations contained in the preceding
paragraph.
 
Mortgage-Backed Securities
The Bond Funds may invest in mortgage-backed securities, some of which are
also considered to be U.S. Government securities. These securities represent
interests in, or are secured by, pools of mortgage loans and provide holders
with payments consisting of both interest and principal as the mortgages in
the underlying mortgage pools are paid off.
 
Mortgage-backed securities include securities guaranteed by the Government
National Mortgage Association ("Ginnie Maes"), securities issued by the
Federal National Mortgage Association ("Fannie Maes"), participation
certificates issued by the Federal Home Life Mortgage Corporation ("Freddie
Macs") and collateralized mortgage obligations issued by a Government
instrumentality or agency ("CMOs"). The timely payment of principal and
interest is backed by the full faith and credit of the U.S. Government in the
case of Ginnie Maes but not for Fannie Maes, Freddie Macs or CMOs.
 
Unscheduled or early payments on the underlying mortgages may shorten the
effective maturities and impact the yield and price of mortgage-backed
securities. A decline in interest rates may lead to increased prepayment of
the underlying mortgages, and the Funds may have to reinvest proceeds received
at lower rates of return. Characteristics of underlying mortgage pools will
vary, and it is not possible to predict completely accurately the realized
yield or average life of a particular mortgage-backed security because of the
principal prepayment feature.
 
Convertible Securities
Certain Funds may invest in convertible securities, which normally provide a
higher yield than the underlying stock but a lower yield than a fixed-income
security without the convertibility feature. The price of the convertible
security normally
 
                                      12
<PAGE>
 
will vary to some degree with changes in the price of the underlying stock,
although the higher yield tends to make the convertible security less volatile
than the underlying common stock. The price of the convertible security also
will vary to some degree inversely with interest rates.
 
INSURANCE LAW RESTRICTIONS
In order for shares of the Investment Company's Funds to remain eligible
investments for the Separate Accounts, it may be necessary, from time to time,
for a Fund to limit its investments in certain types of securities in
accordance with the insurance laws or regulations of the various states in
which the Contracts are sold. Such laws and restrictions as are currently in
effect may limit the Funds' investments in foreign securities and in debt or
equity securities of certain issuers.
 
                       INVESTMENT ADVISORY ARRANGEMENTS
 
THE ADVISER
Subject to the direction and control of the Board of Directors of the
Investment Company, Mutual of America Capital Management Corporation, 320 Park
Avenue, New York, New York 10022 (the "Adviser"), an indirect wholly-owned
subsidiary of Mutual of America Life, manages the investment and reinvestment
of the assets of each Fund pursuant to the Investment Advisory Agreement (the
"Agreement") between the Investment Company and the Adviser. Prior to November
3, 1993, Mutual of America Life was the investment adviser to the Investment
Company; Mutual of America Life's obligations under the Agreement were assumed
by the Adviser on that date. The Adviser had total assets under management of
approximately $7.5 billion at December 31, 1995.
 
The Adviser's duties as investment adviser also include research, making
recommendations to the Board of Directors of the Investment Company and
placing orders for the purchase and sale of securities (see "The Funds'
Expenses"). The Adviser is obligated to provide all of the office space,

"The Subadvisers" below.
 
As compensation for its investment advisory services to each of the Funds of
the Investment Company, the Adviser will receive a fee calculated as a daily
charge at the annual rates of .125% of the value of the net assets in the
Equity Index Fund; .25% of the value of the net assets in the Money Market
Fund; .50% of the value of the net assets in the All America, Bond, Short-Term
Bond, Mid-Term Bond and Composite Funds; and .85% of the value of the net
assets in the Aggressive Equity Fund. The Adviser pays the Subadvisers for
their investment advisory services. See "The Subadvisers" below. During 1995,
the Adviser paid all of the expenses of the Funds other than investment
advisory fees, brokerage commissions and portfolio transaction costs. See "The
Funds' Expenses."

                              THE FUNDS' EXPENSES
 
Each Fund is charged with brokers' commissions, transfer taxes and other fees
relating to that Fund's portfolio transactions, pursuant to the Investment
Advisory Agreement between the Investment Company and the Adviser. In
addition, the Fund is responsible for a number of expenses relating to its
operations, including: directors' fees and expenses; the fees and expenses of
its independent certified public accountants and of its legal counsel;
printing and mailing costs of semi-annual reports to shareholders, Proxy
Statements, Prospectuses, Prospectus Supplements and Statements of Additional
Information; printing of registration statements; bank transaction charges and
custodian's fees; proxy solicitors' fees and expenses, SEC filing fees; any
federal, state or local income or other taxes; any membership fees of the
Investment Company Institute and similar organizations; fidelity bond and
directors' liability insurance premiums; and any extraordinary expenses, such
as indemnification payments or damages awarded in litigation or settlements
made. The Adviser voluntarily limits the expenses of each Fund, other than for
brokers' commissions, transfer taxes and other fees relating to portfolio
transactions, to the amount of the investment advisory fee paid by the Fund to
the Adviser. The Adviser may discontinue making such reimbursements or
payments at any time.
 
                            PORTFOLIO TRANSACTIONS
 
The Adviser is responsible for decisions to buy and sell securities for the
Investment Company as well as for selecting brokers and, where applicable,
negotiating the amount of the commission rate paid. In placing orders, it is
the policy of the Investment Company to obtain the best price and execution
for its contracts.
 
The Adviser and Subadvisers place orders in connection with the purchase and
sale of approved investments with various brokers, including their affiliates.
As a general matter, the Adviser and each Subadviser select broker-dealers
which, in its best judgment, provide prompt and reliable execution at
favorable security prices and reasonable commission rates. They may select
broker-dealers which provide them with research services and may cause a Fund
to pay such broker-dealers commissions which exceed those other broker-dealers
may have charged, if in their view the commissions are reasonable in relation
to the value of the brokerage and/or research services provided by the broker-
dealer. Brokerage arrangements with affiliates of the Adviser or the Sub-
Advisers will be in accordance with the 1940 Act and the rules and regulations
promulgated thereunder. No transactions may be effected by a Fund with an
affiliate of the Adviser or a Sub-Adviser acting as principal for its own
account. When purchasing or selling securities trading on the over-the-counter

                              PURCHASE OF SHARES
 
The Investment Company is offering shares in the Funds, without sales charge,
at present only for purchase by the Insurance Companies for allocation to the
Separate Accounts to fund benefits under the Contracts. The Investment Company
continuously offers shares at prices equal to the respective per share net
asset value of the Funds. Net asset value is determined in the manner set
forth below under "Additional Information--Determination of Net Asset Value."
 
                             REDEMPTION OF SHARES
 
The Investment Company is required to redeem all full and fractional shares of
the Funds for cash. The redemption price is the net asset value per share next
determined after the initial receipt of proper notice of redemption. Payment
upon redemption of Fund shares is normally made within seven days of receipt
of such request (unless redemption is suspended or payment is delayed as
permitted in accordance with SEC regulations).
 
                      DIVIDENDS, DISTRIBUTIONS AND TAXES
 
The Investment Company has in the past elected the special tax treatment
afforded a "regulated investment company" under certain provisions of the
Internal Revenue Code (the "Code"). The Investment Company believes it has
qualified for such treatment and intends to continue to qualify therefor. If
it so qualifies, the Investment Company will not be subject to Federal income
tax on that part of its ordinary income and net realized capital gains which
it distributes to shareholders, thereby avoiding any Federal income tax
liability. Such dividend distributions will be declared and reinvested in
additional full and fractional shares of the Fund to which they relate,
annually, both in the case of net investment income and in the case of net
realized short- or long-term capital gains.
 
For dividend purposes, the net investment income of each Fund will consist of
dividends received and interest accrued by such Fund, plus or minus any
amortized discount or premium, less the estimated expenses of such Fund. To
qualify for
 
                                      15
<PAGE>
 
treatment as a regulated investment company, the Investment Company must,
among other things, derive in each taxable year at least 90% of its gross
income from dividends, interest, gains from the sale or other disposition of
stock or securities, including foreign securities, and other income derived
with respect to the business of investing in stock or securities. In addition,
the Investment Company must derive less than 30% of its gross income in each
taxable year from the disposition of options, futures and forward contracts or
financial investments and foreign currencies, as well as stocks and
securities, in each case held for less than three months. For purposes of
these tests, gross income is determined without regard to losses from the sale
or other disposition of stock or securities. Since the Investment Company has
more than one Fund, each Fund will be treated as a separate corporation for
Federal income tax purposes. Therefore, the investments and results of each
Fund must satisfy the foregoing requirements independently.
 
Although the Investment Company intends to operate so that it will have no
Federal income tax liability, if any such liability is nevertheless incurred,
the investment performance of the Investment Company will be adversely
affected.
 
The Investment Company intends to distribute all net realized long- or short-
term capital gains, if any, to the shareholders of the Fund or Funds to which
such gains are attributable. Realized capital gains and losses of each Fund
are computed separately for the purpose of determining capital gain
distributions. The net capital gain of one Fund will not be reduced by any net
capital losses incurred by the other Funds. Each Fund which has a net capital
gain will be entitled to distribute the full amount of that capital gain as a
capital gain distribution. Each Fund which has a net capital loss will be
entitled to a carryover of that loss which it can apply against its capital
gains in future years.
 
The tax treatment of the Insurance Companies and the Separate Accounts and the
tax implications of an investment in any Contract are described in the
prospectus or brochure for the Contract.
 
                            ADDITIONAL INFORMATION
 
DETERMINATION OF NET ASSET VALUE
The net asset value of the shares of each Fund (i.e., the sum of the value of
the securities held by that Fund plus any cash or other assets including
interest and dividends accrued minus all liabilities including accrued
expenses) is determined once daily by the Adviser immediately after the
declaration of dividends, if any, and is determined as of the time of the
close of trading on the New York Stock Exchange on each day during which such
Exchange is open for trading, with the exception of the Friday following
Thanksgiving and, for 1996, Friday July 5 and Thursday December 26, when the
Investment Company is closed ("Valuation Day"). The net asset value per share
of each Fund for any Valuation Period (i.e., the period beginning on the close
of business on the preceding Valuation Day and ending on the close of business
on the next Valuation Day) is the amount obtained by multiplying the net asset
value per share as of the preceding Valuation Period by that Fund's Change
Factor (described below) for the period beginning on the close of business on
the preceding Valuation Day and ending on the close of business on the next
Valuation Day ("Valuation Period").
 
The Change Factor for each Fund for any Valuation Period is determined as:
 
  (a) the ratio of (i) the net asset value of the Fund at the end of the
  current Valuation Period, before any amounts are allocated to or withdrawn
  from the Fund with respect to that Valuation Period, to (ii) the net asset
  value of the Fund at the end of the preceding Valuation Period, after all
  allocations and withdrawals were made for that period, divided by
 
  (b) 1.00000 plus the component of the annual rate of the Investment
  Adviser's fee against a Fund's assets for the number of days from the end
  of the preceding Valuation Period to the end of the current Valuation
  Period (see "Investment Advisory Arrangements").
 
The value of the assets held in the Investment Company will be determined in
the following manner. Investments for which market quotations are readily
available are valued at the market value of such investments (except that, as
discussed below, money market securities with a remaining maturity of 60 days
or less may be valued at amortized cost). An equity security will be valued at
the last sale price for such security on the principal exchange on which such
security is traded, or at the last bid price on the principal exchange on
which such security is traded if such bid price is of a more recent day than
the last sales price. For any equity security not traded on an exchange but
traded in the over-the-counter market, the value will be the last bid price
available except that securities for which quotations are furnished through
the National Association of Securities Dealers Automated Quotation ("NASDAQ")
system will be valued at the closing best bid price so furnished on the date
of valuation. Debt securities will be valued at a composite fair market value,
"evaluated bid," which may be the last sale price, by a valuation service
selected by the Adviser. Portfolio securities or assets for which market
quotations are not readily available will be valued at fair value as
determined in good faith by the Investment Adviser under the direction of the
Board of Directors of the Investment Company.
 
Money market securities held by the Investment Company with a remaining
maturity of 60 days or less will be valued on an amortized cost basis, which
approximates market value; provided, however, that if the value determined
under the amortized
 
                                      16
<PAGE>
 
cost method is materially different from the actual market value, then even
such short-term money market securities will be valued at market value. Under
the amortized cost method of valuation, the security is initially valued at
cost on the date of purchase (or in the case of securities initially purchased
with more than 60 days remaining to maturity, the market value on the 61st day
prior to maturity), and thereafter the Investment Company assumes a constant
proportionate amortization in value until maturity of any discount or premium.
For purposes of this method of valuation, the maturity of a variable rate
certificate of deposit is deemed to be the next coupon date on which the
interest rate is to be adjusted.
 
Portfolio investments underlying options are valued as described above. Stock
options written by a Fund are valued at the last sale price or, if there has
been no sale that day, at the mean of the last bid and asked price on the
principal exchange where the option is traded, as of the close of trading on
that exchange. The Fund's net value will be increased or decreased by the
difference between the premiums received on writing options and the costs of
liquidating such positions measured by the closing price of the option on the
exchange where traded.
 
When a Fund writes a call option, the amount of the premium is included in the
Fund's assets and an amount is included in its liabilities. The liability
thereafter is adjusted to the current market value of the call. For example,
if the current market value of the call exceeds the premium received, the
excess would be unrealized depreciation; conversely, if the premium exceeds
the current market value, such excess would be unrealized appreciation. If a
call expires or if the Fund enters into a closing purchase transaction, it
realizes a gain (or a loss if the cost of the transaction exceeds the premium
received when the call was written) without regard to any unrealized
appreciation or depreciation in the underlying securities, and the liability
related to such call is extinguished. If a call is exercised, the Fund
realizes a gain or loss from the sale of the underlying securities and the
proceeds of the sale increased by the premium originally received.
 
A premium paid on the purchase of a put will be deducted from a Fund's assets
and an equal amount will be included as an investment and subsequently
adjusted to the current market value of the put. For example, if the current
market value of the put exceeds the premium paid, the excess would be
unrealized appreciation; conversely, if the premium exceeds the current market
value, such excess would be unrealized depreciation.
 
Futures contracts, and options thereon, which are traded on commodities
exchanges, are valued at their official settlement price as of the close of
such commodities exchanges.
 
DESCRIPTION OF THE INVESTMENT COMPANY'S SHARES
The authorized capital stock of the Investment Company consists of one billion
shares of common stock, $.01 par value. The shares of common stock are divided
into eight classes of common stock: Money Market Fund, All America Fund,
Equity Index Fund, Bond Fund, Short-Term Bond Fund, Mid-Term Bond Fund,
Composite Fund and Aggressive Equity Fund. The Investment Company may
establish additional Funds and may allocate its shares either to such new
classes or to one or more of the eight existing classes.
 
All shares of common stock, of whatever class, are entitled to one vote, and
the votes of all classes are cast on an aggregate basis, except on matters
where the interests of the Funds differ. In such a case, the voting is on a
Fund-by-Fund basis. Approval or disapproval by the shareholders of one Fund on
such a matter would not generally be a prerequisite of approval or disapproval
in another Fund. Shareholders in a Fund not affected by a matter generally
would not be entitled to vote on that matter. Examples of matters which would
require a Fund-by-Fund vote are changes in the fundamental investment policy
of a particular Fund and approval of the Investment Advisory Agreement or a
Subadvisory Agreement for the Fund.
 
The shares of each Fund, when issued, will be fully paid and nonassessable and
will have no preference, preemptive, conversion, exchange or similar rights.
Shares do not have cumulative voting rights.
 
Each issued and outstanding share in a Fund is entitled to participate equally
in dividends and distributions declared by such Fund and in the net assets of
such Fund upon liquidation or dissolution remaining after satisfaction of
outstanding liabilities. Accrued liabilities which are not allocable to one or
more Funds will generally be allocated among the Funds in proportion to their
relative net assets. In the unlikely event that any Fund incurred liabilities
in excess of its assets, the other Funds could be liable for such excess.

                        GENERAL INFORMATION AND HISTORY
 
THE INVESTMENT COMPANY
Mutual of America Investment Corporation (the "Investment Company") is a
diversified, open-end management investment company -- a type of company
commonly known as a "mutual fund". It is registered as such under the
Investment Company Act of 1940 (the "Investment Company Act"). The Investment
Company was formed on February 21, 1986 as a Maryland corporation and offers
its shares exclusively to separate accounts of Mutual of America Life
Insurance Company ("Mutual of America Life") and Mutual of America Life's
indirect wholly-owned subsidiary, The American Life Insurance Company of New
York ("American Life"). Mutual of America Life and American Life, together,
hereinafter are sometimes referred to as the "Insurance Companies" and each,
an "Insurance Company". The separate accounts of the Insurance Companies,
together, hereinafter are sometimes referred to as the "Separate Accounts" and
each, a "Separate Account".
 
As a "series" type of mutual fund, the Investment Company issues separate
classes (or series) of stock, each of which represents a separate Fund of
investments. There are currently eight Funds: the Money Market Fund, the All
America Fund, the Equity Index Fund, the Bond Fund, the Short-Term Bond Fund,
the Mid-Term Bond Fund, the Composite Fund, and the Aggressive Equity Fund. As
stated in the Investment Company's Prospectus, the Investment Company is a
successor to Separate Account No. 2 of Mutual of America Life.
 
The Investment Company's shares are sold only to the Insurance Companies for
allocation to the Separate Accounts; thus the Insurance Companies are the only
holders of Investment Company shares and control the Investment Company.
 
                      INVESTMENT POLICIES AND LIMITATIONS
 
The following supplements the information contained in the Investment
Company's Prospectus concerning the investment policies and limitations of its
Funds. For information relating to the Funds' investment objectives, see
"Investment Objectives and Policies of the Funds", and for information about
the Adviser and the Subadvisers, see "Investment Advisory Arrangements" in the
Prospectus and in this Statement of Additional Information.
 
Fixed-income securities which are rated in the lower rating categories of the
nationally recognized rating services (Ba or lower by Moody's and BB or lower
by Standard & Poor's), or unrated securities of comparable quality, in which
the Bond Funds may to a limited extent invest, are commonly known as "junk
bonds." Junk bonds are regarded as being predominantly speculative as to the
issuer's ability to make payments of principal and interest. Investment in
such securities involves substantial risk. Junk bonds may be issued by less
creditworthy companies or by larger, highly leveraged companies, and are
frequently issued in corporate restructurings such as mergers and leveraged
buy-outs. Such securities are particularly vulnerable to adverse changes in
the issuer's industry and in general economic conditions. Junk bonds
frequently are junior obligations of their issuers, so that in the event of
the issuer's bankruptcy, claims of the holders of junk bonds will be satisfied
only after satisfaction of the claims of senior security holders. While the
junk bonds in which the Bond Funds may invest normally would not include
securities which, at the time of investment, are in default or the issuers of
which are in bankruptcy, there can be no assurance that such events would not
occur after the Bond Funds purchase a particular security, in which case the
Bond Funds may experience losses and incur costs.
 
Junk bonds tend to be more volatile than higher-rated fixed-income securities,
so that adverse economic events may have a greater impact on the prices of
junk bonds than on higher-rated fixed-income securities. Like higher-rated
fixed-income securities, junk bonds generally are purchased and sold through
dealers who make a market in such securities for their own accounts. However,
there are fewer dealers in the junk bond market, which may be less liquid than
the market for higher-rated fixed-income securities, even under normal
economic conditions. Also, there may be significant disparities in the prices
quoted for junk bonds by various dealers. Adverse economic conditions or
investor perceptions (whether or not based on economic fundamentals) may
impair the liquidity of this market, and may cause the prices the Bond Funds
may receive for any junk bonds to be reduced, or might cause the Bond Funds to
experience difficulty in liquidating a portion of its portfolios. Under such
conditions, judgment may play a greater role in valuing certain of the Bond
Funds' securities than in the case of securities trading in a more liquid
market.
 
While the Funds other than the Bond Funds do not purchase junk bonds, the
fixed-income securities they purchase may become junk bonds as a result of
impairments of the issuer's credit. In such instances, the Fund holding a junk
bond will consider disposing of it if, in management's judgment, it is in the
Fund's best interest to do so.
 
Reference is made to "Investment Objectives and Policies of the Funds" in the
Prospectus for a more complete discussion of the investment objectives and
policies of the Investment Company. The following is a description of the
money market securities the Money Market Fund may invest in as referred to in
the "Investment Objectives and Policies of the Funds" section of the
Prospectus.
 
                                     SAI-2
<PAGE>
 
U.S. Government Obligations. Securities issued or guaranteed as to principal
and interest by the United States Government include a variety of Treasury
securities, which differ only in their interest rates, maturities and times of
issuance. Treasury bills have a maturity of one year or less. Treasury notes
have maturities of one to seven years and Treasury bonds generally have a
maturity of greater than five years.
 
Agencies of the United States Government which issue or guarantee obligations
include, among others, Export-Import Bank of the United States, Farmers Home
Administration, Federal Housing Administration, Government National Mortgage
Association, Student Loan Marketing Association, Maritime Administration,
Small Business Administration and the Tennessee Valley Authority. Obligations
of instrumentalities of the United States Government include securities issued
or guaranteed by, among others, Federal Farm Credit Banks, Federal National
Mortgage Association, Federal Home Loan Banks, Federal Home Loan Mortgage
Corporation, Federal Intermediate Credit Banks, Federal Land Banks and Banks
for Cooperatives. Some of these securities are supported by the full faith and
credit of the U.S. Treasury; others are supported by the right of the issuer
to borrow from the Treasury, while still others are supported only by the
credit of the instrumentality.
 
Shares of the Investment Company are not themselves insured or guaranteed by
the United States Government or any agency thereof.
 
Certificates of Deposit. Certificates of deposit are generally short term,
interest-bearing negotiable certificates issued by banks or savings and loan
associations against funds deposited in the issuing institution.
 
Time Deposits. Time deposits are deposits in a bank or other financial
institution for a specified period of time at fixed interest rate of which a
negotiable certificate is not received.
 
Bankers' Acceptance. A bankers' acceptance is a 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 well as the bank, which unconditionally
guarantees to pay the draft at its face amount on the maturity date. Most
acceptances have maturities of six months or less and are traded in secondary
markets prior to maturity.
 
Commercial Paper. Commercial paper refers to 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.
 
Variable Amount Floating Rate Notes. Variable floating rate notes are short-
term, unsecured promissory notes issued by corporations to finance short-term
credit needs. These are interest-bearing notes on which the interest rate
generally fluctuates on a weekly basis.
 
Corporate Debt Securities. Corporate debt securities with a remaining maturity
of less than one year tend to become extremely liquid and are traded as money
market securities. Such issues with between one and two years remaining to
maturity tend to have greater liquidity and considerably less market value
fluctuations than longer term issues.
 
REPURCHASE AGREEMENTS
Under a repurchase agreement, underlying debt instruments are acquired for a
relatively short period (usually not more than one week and never more than
one year) subject to an obligation of the seller to repurchase (and the
appropriate Fund to resell) the instrument at a fixed price and time, thereby
determining the yield during the Fund's holding period. This results in a
fixed rate of return insulated from market fluctuation during such period.
Accrued interest on the underlying security will not be included for purposes
of valuing a Fund's assets.
 
Repurchase agreements have the characteristics of loans by a Fund, and will be
fully collateralized (either with physical securities or evidence of book
entry transfer to the account of the custodian bank) at all times. During the
term of the repurchase agreement the Fund retains the security subject to the
repurchase agreement as collateral securing the seller's repurchase
obligation, continually monitors the market value of the security subject to
the agreement and requires the Fund's seller to deposit with the Fund
additional collateral equal to any amount by which the market value of the
security subject to the repurchase agreement falls below the resale amount
provided under the repurchase agreement. The Funds enter into repurchase
agreements only with member banks of the Federal Reserve System, and with
primary dealers in U.S. Government securities whose creditworthiness has been
reviewed and found satisfactory by the management of the Investment Company,
and who have, therefore, been determined to present minimal credit risk.
 
Securities underlying repurchase agreements will be limited to certificates of
deposit, commercial paper, bankers' acceptances, or obligations issued or
guaranteed by the United States Government or its agencies or
instrumentalities, in which the Funds may otherwise invest.
 
 
                                     SAI-3
<PAGE>
 
If a seller of a repurchase agreement defaults and does not repurchase the
security subject to the agreement, the Fund would look to the collateral
security underlying the seller's repurchase agreement, including the
securities subject to the repurchase agreement, for satisfaction of the
seller's obligation to the Fund; in such event the Fund might incur
disposition costs in liquidating the collateral and might suffer a loss if the
value of the collateral declines. In addition, there is a risk that, if the
issuer of the repurchase agreement becomes involved in bankruptcy proceedings,
the Fund might be delayed or prevented from liquidating the underlying
security or otherwise obtaining it for its own purposes.
 
OPTIONS AND FUTURES
As described in the Prospectus, the Funds may enter into transactions in
options, futures contracts and options on futures contracts on securities and
indexes of securities for hedging purposes only. With respect to options and
futures, the Funds may engage in strategies which include buying and selling
covered calls and puts and buying and selling call options on groups of
securities and on the futures of groups of securities.
 
A call option is a short-term contract (generally having a duration of nine
months or less) which gives the purchaser of the option the right to purchase
the underlying security at a fixed exercise price at any time prior to the
expiration of the option regardless of the market price of the security during
the option period. As consideration for the call option, the purchaser pays a
Fund (the seller) a premium, which the Fund retains whether or not the option
is exercised. The seller of the call option has the obligation, upon the
exercise of the option by the purchaser, to sell the underlying security at
the exercise price at any time during the option period. The selling of a call
option will benefit a Fund if, over the option period, the underlying security
declines in value or does not appreciate above the aggregate of the exercise
price and the premium. However, the Fund risks an "opportunity loss" of
profits if the underlying security appreciates above the aggregate value of
the exercise price and the premium.
 
A Fund may close out a position acquired through selling a call option by
buying a call option on the same security with the same exercise price and
expiration date as the call option which it had previously sold on that
security. Depending on the premium for the call option purchased by the Fund,
the Fund will realize a profit or loss on the transaction.
 
A put option is a similar short-term contract that gives the purchaser of the
option the right to sell the underlying security at a fixed exercise price at
any time prior to the expiration of the option regardless of the market price
of the security during the option period. As consideration for the put option
a Fund (the purchaser) pays the seller a premium, which the seller retains
whether or not the option is exercised. The seller of the put option has the
obligation, upon the exercise of the option by the purchaser, to purchase the
underlying security at the exercise price at any time during the option
period. The buying of a covered put contract limits the downside exposure for
the investment in the underlying security to the combination of the exercise
price less the premium paid. The risk of purchasing a put is that the market
price of the underlying stock prevailing on the expiration date may be above
the option's exercise price. In that case the option would expire worthless
and the entire premium would be lost.
 
A Fund may close out a position acquired through buying a put option by
selling a put option on the same security with the same exercise price and
expiration date as the put option which it had previously bought on the
security. Depending on the premium of the put option sold by the Fund, the
Fund will realize a profit or loss on the transaction.
 
In addition to options (both calls and puts) on individual securities, the
Funds may purchase and sell options on indexes of securities such as the
Standard & Poor's 100 Index, the Standard & Poor's 500 Stock Index and the New
York Stock Exchange Composite Index. Options on stock indexes, like options on
individuals securities, are traded on national securities exchanges, regulated
by the Securities and Exchange Commission such as the Chicago Board Options
Exchange, the American Stock Exchange and the New York Stock Exchange. The
Funds may sell futures contracts, and purchase options on futures contracts,
on the same types of stock indexes. Options, futures contracts and options on
futures contracts can be used in anticipation of or in a general market or
market sector decline that may adversely affect the market value of a Fund's
portfolio of securities. To the extent that a Fund's portfolio of securities
changes in value in correlation with a given stock index, hedging transactions
in options, futures contracts or options on futures contracts could reduce the
risk to the portfolio of a market decline, and, by so doing, provide an
alternative to the liquidation of securities' positions in the portfolio with
resultant transactions costs. The stock index underlying an option or futures
contract assigns weighted values to the stocks involved in the index, and the
value of the index fluctuates with changes in the market values of the stocks
so included.
 
A futures contract on fixed income securities requires the seller to deliver,
and the purchaser to accept delivery of, a stated quantity of a given type of
fixed income security for a fixed price at a specified time in the future. A
futures contract or option on a stock index provides for the making and
acceptance of a cash settlement equal to the change in value of a hypothetical
portfolio of stocks between the time the contract is entered into and the time
it is liquidated, times a fixed multiplier. Futures contracts may be traded
domestically only on exchanges which have been designated as "contract
 
                                     SAI-4
<PAGE>
 
markets" by the Commodity Futures Trading Commission ("CFTC"), such as the
Chicago Board of Trade. All transactions are settled through the clearing
house of the contract market, which acts as the guarantor of the performance
of each party to all futures contracts cleared.
 
An option on a futures contract provides the purchaser with the right, but not
the obligation, to enter into a "long" position in the underlying futures
contract (in the case of a call option on a futures contract), or a "short"
position in the underlying futures contract (in the case of a put option on a
futures contract), at a fixed price up to a stated expiration date. Upon
exercise of the option by the holder, the contract market clearing house
establishes a corresponding short position for the writer of the option, in
the case of a call option, or a corresponding long position in the case of a
put option. In the event that an option is exercised, the parties are subject
to all of the risks associated with the trading of futures contracts, such as
payment of margin deposits.
 
Options on futures contracts are traded on the same contract markets as the
underlying futures contracts, subject to the performance guarantee of the
contract market clearing house. A futures contract or an option on a futures
contract may be closed out prior to maturity or expiration by entering into a
liquidating transaction in the same instrument on the contract market on which
the original position was established.
 
Unlike a Fund purchasing or selling a security, no price is paid or received
by a Fund upon the purchase or sale of a futures contract. Initially, a Fund
will be required to deposit with the Fund's custodian in the broker's name an
amount of cash or U.S. Treasury bills equal to approximately 5% of the
contract amount. This amount is known as "initial margin." The nature of
initial margin in futures transactions is different from that of margin in
security transactions in that futures contract margin does not involve the
borrowing of funds by the customer to finance the transactions. Rather, the
initial margin is in the nature of a performance bond or good faith deposit on
the contract which is returned to a Fund upon termination of the futures
contract assuming all contractual obligations have been satisfied. Subsequent
payments, called maintenance margin, to and from the broker, will be made on a
daily or intraday basis as the price of the underlying instrument or stock
index fluctuates making the long and short positions in the futures contract
more or less valuable, a process known as mark to market. For example, when a
Fund has purchased a stock index futures contract and the price of the
underlying stock index has risen, that position will have increased in value
and the Fund will receive from the broker a variation margin payment equal to
that increase in value. Conversely, where a Fund has purchased a stock index
futures contract and the price of the underlying stock index has declined, the
position would be less valuable and the Fund would be required to make a
variation margin payment to the broker. At any time prior to expiration of the
futures contract, a Fund may elect to close the position by taking an opposite
position which will operate to terminate the Fund's position in the futures
contract. A final determination of margin is then made, additional cash is
required to be paid by or released to the Fund, and the Fund realizes a loss
or a gain.
 
Transactions in options, futures contracts and options on futures contracts
may increase a Fund's transaction costs and portfolio turnover rate and will
be initiated only when consistent with a Fund's investment objectives.
 
The trading of options, futures contracts and options on futures contracts
also involves risks, in addition to those set forth in the Prospectus. For
example, the trading of options on futures contracts entails the risk that
changes in the value of the underlying futures contract will not be fully
reflected in the value of the option. Further, the ability to profit from the
purchase of an option and liquidate the underlying futures contract, is
subject to the risks of margin payments and the availability of a liquid
market. With respect to options and options on futures contracts, the Funds
are subject to the risk of market movements between the time that the option
is exercised and the time of performance thereunder. In writing a covered call
option on a security or a stock index, the Funds also incur the risk that
changes in the value of the instruments used to cover the position will not
correlate precisely with changes in the value of the option or underlying the
index or instrument.
 
The exchanges on which options, futures contracts and options on futures
contracts are traded may impose limitations governing the maximum number of
positions on the same side of the market and involving the same underlying
instrument which may be held by a single investor, whether acting alone or in
concert with others (regardless of whether such contracts are held on the same
or different exchanges or held or written in one or more accounts or through
one or more brokers).
 
The opening of a futures position and the writing of an option are
transactions which involve substantial leverage. As a result, relatively small
movements in the price of the contract can result in substantial unrealized
gains or losses. Because the Funds will engage in transactions in options,
futures contracts and options on futures contracts on securities and indexes
of securities for hedging purposes only, any losses incurred in connection
with these transactions should, if the hedging strategy is successful, be
offset by increases in the value of securities or other assets held by the
Funds or decreases in the prices of securities or other assets the Fund
intends to acquire. Were a Fund to write options on securities or options on
stock indexes for other than hedging purposes, the margin requirements
associated with such transactions could expose the Fund to greater risk.
 
                                     SAI-5

Regulations of the CFTC require that a Fund enter into transactions in futures
contracts and options on futures contracts for hedging purposes only or
otherwise to limit its initial futures margins and related option premiums
paid to an amount not to exceed 5% of the value of the Fund's assets, in order
to assure that the Fund is not deemed to be a "commodity pool" and the
Investment Company is not a "commodity pool operator" as defined in CFTC
regulations.
 
                            INVESTMENT RESTRICTIONS
 
The following investment restrictions are fundamental policies and may not be
changed without the approval of a majority of the outstanding voting shares of
the affected Fund. None of the Funds will:
 
1. purchase or sell options or futures except those listed on a domestic
   exchange;
2. trade in foreign exchange, or invest in securities of foreign issuers if at
   the time of acquisition more than 20% of its total assets, taken at market
   value at the time of the investment, would be invested in such securities
   (see "Foreign Securities");
3. make an investment in order to exercise control of management over a
   company (either singly or together with other Funds);
4. underwrite the securities of other companies, including purchasing
   securities that are restricted under the Securities Act of 1933 ("1933
   Act") or rules or regulations issued under the 1933 Act (restricted
   securities cannot be sold publicly until they are registered under the 1933
   Act);
5. make short sales, except when the Fund has, by reason of ownership of other
   securities, the right to obtain securities of equivalent kind and amount
   that will be held so long as they are in a short position,
6. purchase commodities or commodity contracts;
7. with respect to at least 75% of the value of its total assets, invest more
   than 5% of its total assets in the securities of any one issuer (including
   repurchase agreements with any one bank), other than securities issued or
   guaranteed by the United States Government or its agencies or
   instrumentalities (see the caption entitled "The Money Market Fund" in the
   Prospectus for more restrictive policies relating to that fund);
8. with respect to at least 75% of the value of its total assets, purchase
   more than 10% of the outstanding voting securities of an issuer, except
   that such restriction shall not apply to securities issued or guaranteed by
   the United States Government or its agencies or instrumentalities;
9. issue senior securities except that each Fund may borrow as described in
   restriction 13 below (the issuance and sale of options and futures not
   being considered the issuance of senior securities);
10. make an investment in an industry if that investment would make the Fund's
    holding in that industry exceed 25% of the Fund's total assets, except for
    the Bond Fund, the Short-Term Bond Fund and the Mid-Term Bond Fund, each
    of which may invest up to 75% of its total assets in the electric, gas
    and/or telephone utilities industries, as described under the caption
    "Investment Objectives and Policies of the Funds--The Bond Fund, the
    Short-Term Bond Fund and the Mid-Term Bond Fund" in the Prospectus;
11. purchase real estate or mortgages directly. The All America and Aggressive
    Equity Funds may, however, buy shares of real estate investment trusts
    listed on stock exchanges or reported on the National Association of
    Securities Dealers Automated Quotations ("NASDAQ") system, and the Bond
    Fund, the Short-Term Bond Fund and the Mid-Term Bond Fund may each buy
    mortgage-backed debt issues;
12. invest more than 5% of its total assets in the securities of any one
    registered investment company. A Fund may not own more than 3% of an
    investment company's outstanding voting securities, and total holdings of
    investment company securities may not exceed 10% of the value of a Fund's
    total assets;
13. purchase any security on margin or borrow money, except from banks for
    temporary purposes, or pledge its assets unless to secure such borrowing.
    The Funds may borrow money from or pledge their assets to banks in order
    to transfer funds for various purposes, as required, without interfering
    with the orderly liquidation of securities in their portfolios, but not
    for leveraging purposes. Such borrowings may not exceed 5% of the value of
    a fund's total assets at market value;
14. make loans, except loans of portfolio securities (not exceeding 30% of the
    value of its total assets at market value), or loans through entry into
    repurchase agreements (the purchase of publicly traded debt obligations
    not being considered the making of a loan);
15. invest more than 10% of its total assets in repurchase agreements or time
    deposits maturing in more than seven days or in portfolio securities not
    readily marketable; or
16. purchase oil and gas interests, except that the Funds may purchase
    securities of issuers that invest in oil or gas interests. The Money
    Market Fund will not purchase equity securities, voting securities, local
    or state government securities, or corporate debt or other than those
    types of securities specifically mentioned in its investment objectives.

If a percentage restriction is adhered to at the time of investment, a later
increase or decrease in percentage beyond the specified limit resulting from a
change in values of portfolio securities or amount of net assets will not be
considered a violation.

                       INVESTMENT ADVISORY ARRANGEMENTS
 
Investment Adviser. The Investment Company's investment adviser is Mutual of
America Capital Management Corporation (the "Adviser"), an indirect wholly-
owned subsidiary of Mutual of America Life. Prior to November 3, 1993, Mutual
of America Life was the investment adviser to the Investment Company, pursuant
to an investment advisory agreement between the Investment Company and Mutual
of America Life, as investment adviser.
 
Subject at all times to the supervision and approval of the Investment
Company's Board of Directors and except as discussed below under
"Subadvisers", the Adviser renders investment advisory services with respect
to the Money Market, All America, Equity Index, Bond, Short-Term Bond, Mid-
Term Bond, Composite and Aggressive Equity Funds in a manner consistent with
their stated investment policies, objectives and restrictions. In connection
therewith, the Adviser advises the Investment Company as to what investments
should be purchased and sold and places orders for all such purchases and
sales on behalf of the Investment Company. The Adviser is a registered
investment adviser.
 
Advisory Fees. As compensation for its investment advisory services to each of
the Funds of the Investment Company, the Adviser will receive a fee calculated
as a daily charge at the annual rates of .125% of the value of the net assets
in the Equity Index Fund; .25% of the value of the net assets in the Money
Market Fund; and .50% of the value of the net assets in the All America, Bond,
Short-Term Bond, Mid-Term Bond and Composite Funds; and .85% of the value of
the net assets in the Aggressive Equity Fund. The total amount of Investment
Advisory fees paid in 1995 by the Investment Company to Mutual of America Life
was $5,627,349, of which $211,088 was paid by the Money Market Fund;
$2,248,272 was paid by the All America Fund; $1,391,001 was paid by the Bond
Fund; $1,272,077 was paid by the Composite Fund; $40,145 was paid by the
Equity Index Fund; $14,478 was paid by the Short-Term Bond Fund; $124,503 was
paid by the Mid-Term Bond Fund; and $325,785 was paid by the Aggressive Equity
Fund. The total amount of Investment Advisory fees paid in 1994 by the
Investment Company to the Adviser was $4,810,484, of which $119,452 was paid
by the Money Market Fund;
 
                                     SAI-8
<PAGE>
 
$1,933,632 was paid by the All America Fund; $33,192 was paid by the Equity
Index Fund; $1,324,071 was paid by the Bond Fund; $11,466 was paid by the
Short-Term Bond Fund; $100,231 was paid by the Mid-Term Bond Fund; $1,140,308
was paid by the Composite Fund; and $148,132 was paid by the Aggressive Equity
Fund.
 
Advisory Agreement. The Investment Advisory Agreement (the "Advisory
Agreement") was last approved by a majority of the non-interested members of
the Investment Company's Board of Directors (the "non-interested directors")
on February 23, 1993, and by a majority vote of each Fund's shareholders on
April 13, 1993. Pursuant to an assumption agreement dated November 3, 1993,
the Adviser assumed the rights and duties of Mutual of America Life under the
investment advisory agreement. Supplements to the Advisory Agreement to permit
the Adviser to enter into subadvisory agreements for the All America Fund and
Aggressive Equity Fund were approved by a majority of the non-interested
directors on November 16, 1993. The supplement relating to the All America
Fund was approved by a majority vote of the Fund's shareholders on April 14,
1994, and the supplement relating to the Aggressive Equity Fund was approved
by a vote of the Fund's shareholders on May 1, 1995.
 
The Advisory Agreement terminates automatically in the event of its assignment
or, with respect to any Fund, upon 60 days' notice given by the Investment
Company's Board of Directors, by the Adviser or by majority vote (as defined
in the Investment Company Act of 1940 and the rules thereunder) of the Fund's
shares. Otherwise, the Advisory Agreement will continue in force with respect
to any Fund so long as its continuance is approved at least annually by (i) a
majority of the members of the Investment Company's Board of Directors, or
(ii) a majority vote (as defined in the Investment Company Act of 1940 and the
rules thereunder) of the Fund's Shareholders; provided that in either event
such continuance will also be approved by the vote of a majority of directors
who are not interested persons (as defined in the Investment Company Act of
1940).
 
Under the Advisory Agreement, the Adviser agrees to provide investment
management services to the Investment Company. Such services include
performing investment research and evaluating pertinent economic, statistical
and financial data; consultation with the Investment Company's Board of
Directors and furnishing to the Investment Company's Board of Directors
recommendations with respect to the overall investment plan; implementation of
the overall investment plan, including carrying out decisions to acquire or
dispose of investments; management of investments; reporting to the Investment
Company's Board of Directors on a regular basis on the implementation of the
investment plan and the management of investments; maintaining all required
records; making arrangements for the safekeeping of assets; and providing
office space facilities, equipment, material and personnel necessary to
fulfill its obligations.
 
The Adviser is responsible for all expenses incurred in performing the
investment advisory services, including compensation of officers and payment
of office expenses, trading investment and investment management.
 
Each Fund will pay all other expenses incurred in its operation, including
brokers' commissions, transfer taxes and other fees relating to the Fund's
portfolio transactions, directors' fees and expenses, fees and expenses of its
independent certified public accountants and of its legal counsel, the cost of
the printing and mailing of semi-annual reports to shareholders, Proxy
Statements, Prospectuses, Prospectus Supplements and Statements of Additional
Information, the printing of registration statements, bank transaction charges
and custodian's fees, any proxy solicitors' fees and expenses, SEC filing
fees, any federal, state or local income or other taxes, any membership fees
of the Investment Company Institute and similar organizations, fidelity bond
and directors' liability insurance premiums, as well as any extraordinary
expenses, such as indemnification payments or damages awarded in litigation or
settlements made. The Adviser voluntarily reimburses or pays all of the
expenses of the Funds other than advisory fees, brokers' commissions, transfer
taxes and other fees relating to the Funds' portfolio transactions and paid
all such expenses in 1995. The payment of expenses results in an increase to
each Fund's yield or total return. The Adviser may discontinue or modify its
policy of paying expenses of the Funds at any time.
 
The Subadvisers. With respect to the management of a portion of the
approximately 30% of the assets allocated to the All America Fund (the "Active
Assets"), the Adviser engages subadvisory services of three subadvisers--
Palley-Needelman Asset Management, Inc. ("Palley-Needelman"), Oak Associates,
Ltd. ("Oak Associates") and Fred Alger Management, Inc. ("Alger Management"),
(each a "Subadviser", and together the "Subadvisers"). Each Subadviser is
registered as an investment adviser under the Investment Advisers Act of 1940.
 
Each of the Subadvisers, with respect to the assets for which it acts as
subadviser, shall, subject to the supervision of the Adviser and the Board of
Directors of the Investment Company, render investment advisory services and
assume the obligations including research, making recommendations and regular
reports to the Board of Directors of the Investment Company, maintenance of
records, and providing all the office space, facilities, equipment, material and
personnel necessary to fulfill its obligations under the Subadvisory Agreement.
 
                                     SAI-9

Subadvisory Fees. Each of the Subadvisory Agreements provides that the Adviser
will pay to the Subadviser an amount calculated daily at the following annual
rates: Palley-Needelman, .30%; Oak Associates, .30%; and Alger Management,
 .45%; of the value of the net assets for which the Subadviser is providing
investment advisory services. The Subadvisory Agreement between the Adviser
and Mitchell Hutchins Institutional Investors, Inc. ("Mitchell Hutchins") was
terminated on June 15, 1995, and the Subadvisory Agreement between the Adviser
and C.J. Lawrence/Deutsche Bank Securities Corporation ("C.J. Lawrence") was
terminated on September 30, 1995, which provided for subadvisory fees of .50%
for Mitchell Hutchins, and .50% of the first $15 million and .30% thereafter
for C.J. Lawrence, of the value of the net assets for which subadvisory
services were provided.
 
The fees paid to the Subadvisers during 1994 were as follows: Palley-
Needelman, $43,165; Oak Associates, $38,206; Alger Management, $105,887;
Mitchell Hutchins, $61,950; and C.J. Lawrence, $38,537. The fees paid during
1995 by the Adviser to the Subadvisers totalled $654,396, and the amounts to
each Subadviser were Palley-Needelman, $132,923; Oak Associates, $150,434;
Alger Management, $236,298; Mitchell Hutchins, $72,875; and C.J. Lawrence,
$61,866.
 
Subadvisory Agreements. The Subadvisory Agreements were approved by a majority
of the non-interested directors on February 22, 1994. The Subadvisory
Agreements with the Subadvisers for the All America Fund were approved by a
majority vote of the Fund's shareholders on April 14, 1994 and by a majority
vote of the Aggressive Equity Fund's shareholders on May 1, 1994.
 
Each agreement terminates automatically in the event of its assignment or upon
60 days' notice given by the Investment Company's Board of Directors, by the
Adviser or by a majority vote (as defined in the Investment Company Act of
1940 and the rules thereunder) of the related Fund's shares. Otherwise, each
Subadvisory Agreement will continue in force so long as its continuance is
approved at least annually by (i) a majority of the members of the Investment
Company's Board of Directors, or (ii) a majority vote (as defined in the
Investment Company Act of 1940 and the rules thereunder) of the All America
Fund's shareholders; provided that in either event such continuance will also
be approved by the vote of a majority of directors who are not interested
persons (as defined in the Investment Company Act of 1940).
 
                     PORTFOLIO TRANSACTIONS AND BROKERAGE
 
The Adviser and each Subadviser are responsible for decisions to buy and sell
securities for the Funds of the Investment Company for which they provide
services as well as for selecting brokers and, where applicable, negotiating
the amount of the commission rate paid. As a general matter, the Adviser and
Subadvisers select broker-dealers which, in their best judgment, provide
prompt and reliable execution at favorable security prices and reasonable
commission rates. The Adviser and Subadvisers may place certain orders with
their affiliates, subject to the requirements of the 1940 Act.
 
During 1995, Mutual of America Securities Corporation, an affiliate of the
Adviser, acted as an introducing broker for certain securities transactions.
In connection with such activities, Mutual of America Securities Corporation
received $79,000, which represented approximately 7.9% of the total brokerage
commissions paid by the Investment Company and approximately 5.8% of the
aggregate dollars of transactions effected by the Investment Company. In
addition, Deutsche Bank Securities Corporation and Fred Alger & Co., each an
affiliate of a Subadviser, received brokerage commissions during 1995.
Deutsche Bank Securities Corporation received $12,000 and Alger & Co. received
$61,000, which represented approximately 1.2% and 6.1%, respectively, of the
total brokerage commissions paid by the Investment Company and approximately
1.42% and 4.52%, respectively, of the aggregate dollars of transactions
effected by the Investment Company. During 1994, Mutual of America Securities
Corporation, an affiliate of the Adviser, acted as an introducing broker for
certain securities transactions. In connection with such activities, Mutual of
America Securities Corporation received $258,600, which represented
approximately 15% of the total brokerage commissions paid by the Investment
Company and approximately 16% of the aggregate dollars of transactions
effected by the Investment Company. In addition, Deutsche Bank Securities
Corporation and Fred Alger & Co., each an affiliate of a Subadviser, received
brokerage commissions during 1994. Deutsche Bank Securities Corporation
received $41,450 and Alger & Co. received $54,590, which represented
approximately 2.4% and 3.16%, respectively, of the total brokerage commissions
paid by the Investment Company and approximately 1.9% and 1.62%, respectively,
of the aggregate dollars of transactions effected by the Investment Company.
When purchasing or selling securities trading on the over-the-counter market,
the Adviser, and each Subadviser, will generally execute the transaction with
a broker engaged in making a market for such securities.
 
Brokerage commissions are negotiated, as there are no standard rates. All
brokerage firms provide the service of execution of the order made; some
brokerage firms also provide research and statistical data, and research
reports on particular
 
                                    SAI-10
<PAGE>
 
companies and industries are customarily provided by brokerage firms to large
investors. In negotiating commissions, consideration is given by the Adviser,
and each Subadviser, to the use and value of the data and to the quality of
execution provided. The valuation of such data may be judged with reference to
a particular order or, alternatively, may be judged in terms of its value to
the overall management of the Investment Company.
 
The Adviser, and each Subadviser, will place orders with brokers providing
useful research and statistical data services if reasonable commissions can be
negotiated for the total services furnished even though lower commissions may
be available from brokers not providing such services. The Adviser, and each
Subadviser, uses these services in connection with all of its investment
activities, and some of the data or services obtained in connection with the
execution of transactions for the Investment Company may be used in managing
other investment accounts. Conversely, data or services obtained in connection
with transactions in other accounts may be used by the Adviser, and each
Subadviser, in providing investment advice to the Investment Company. To the
extent that the Adviser, and each Subadviser, uses research and statistical
data services so obtained, its expenses may be reduced and such data has
therefore been and is one of the factors considered by the Adviser, and each
Subadviser, in determining its fee for investment advisory services.
 
At times, transactions for the Investment Company may be executed together
with purchases or sales of the same security for other accounts of the Adviser
or a Subadviser. When making concurrent transactions for several accounts, an
effort is made to allocate executions fairly among them. Transactions of this
type are executed only when the Adviser, or a Subadviser, believes it to be in
the best interests of the affected Fund(s), as well as any other accounts
involved. However, the possibility exists that concurrent executions may work
out to the disadvantage of the Fund(s) involved.
 
PORTFOLIO TURNOVER
 
Each Fund has a different expected rate of portfolio turnover; however, rate
of portfolio turnover will not be a limiting factor when management of the
Investment Company deems it appropriate to purchase or sell securities for a
Fund.
 
The Money Market Fund will seek maximum return on its assets by trading to
take advantage of short-term market variations. For this reason, and because
of the short-term nature of the money market instruments that will be
purchased by the Fund, the Money Market Fund will probably have a high annual
rate of portfolio turnover that cannot be predicted (although the Money Market
Fund may be deemed not to have a calculable turnover rate for reporting
purposes because all or most of its portfolio securities are excluded under
the method of calculation of turnover rate prescribed by the Securities and
Exchange Commission).
 
Neither the Aggressive Equity Fund nor the Active Assets of the All America
Fund will hold all of its investments for an extended period so that the
annual rate of portfolio turnover of each is expected to average about 70%.
 
Since the Equity Index Fund and the Indexed Assets of the All America Fund
will each attempt to duplicate the investment results of the S&P 500 Index,
each is expected to have an annual portfolio turnover rate that is generally
lower than 50%.
 
The Bond Funds may realize short-term gains to the extent such realizations
are considered advantageous in light of existing market conditions. The annual
rate of portfolio turnover of the Bond Funds is not expected to average in
excess of 200%.
 
Since the types and proportions of the Composite Fund's assets are expected to
change frequently to reflect prevailing market conditions, no annual rate of
portfolio turnover can be predicted for the Fund. Within the Fund, it would be
expected that the annual rate of portfolio turnover for the equity securities
invested in the Fund would be similar to the annual rate of portfolio turnover
of the Aggressive Equity Fund and the Active Assets of the All America Fund,
and the annual rate of portfolio turnover for the publicly traded debt
securities invested in by the Fund would be similar to the annual rate of
portfolio turnover of the Bond Funds.
 
                      PURCHASE AND PRICING OF SECURITIES
 
As stated in the Prospectus, the Investment Company will offer and sell its
shares at each Fund's per share net asset value, which will be determined in
the manner set forth below.
 
The net asset value of the shares of each Fund (i.e., the sum of the value of
the securities held by that Fund plus any cash or other assets including
accrued expenses) is determined once daily by the Investment Adviser
immediately after the declaration of dividends, if any, and is determined as
of the time of the close of trading on the New York Stock Exchange on each day
during which such Exchange is open for trading, with the exception of the
Friday after Thanksgiving and, for 1996, Friday July 5 when the Investment
Company is closed ("Valuation Day"). The net asset value per share of each
Fund for any Valuation Period (i.e., the period beginning on the close of
business on the preceding Valuation Day and ending on the close of business on
the next Valuation Day), is the amount obtained by multiplying the net asset
value per share as of
 
                                    SAI-11
<PAGE>
 
the preceding Valuation Period by that Fund's Change Factor (described below)
for the period beginning on the close of business on the preceding Valuation
Day and ending on the close of business on the next Valuation Day ("Valuation
Period").
 
The Change Factor for each Fund for any Valuation Period is determined as:
  (a) the ratio of (i) the net asset value of the Fund at the end of the
  current Valuation Period, before any amounts are allocated to or withdrawn
  from the Fund with respect to that Valuation Period, to (ii) the net asset
  value of the Fund at the end of the preceding Valuation Period, after all
  allocations and withdrawals were made for that period, divided by
  (b) 1.00000 plus the component of the annual rate of the Investment
  Adviser's fee against a Fund's assets for the number of days from the end
  of the preceding Valuation Period to the end of the current Valuation
  Period (see "Investment Advisory Arrangements").
 
The methods used to value the assets of each Fund are set forth in the
Prospectus.
 
                       YIELD AND PERFORMANCE INFORMATION
 
Performance information is computed separately for each Fund in accordance
with the formulas described below. At any time in the future, total return and
yields may be higher or lower than in the past and there can be no assurance
that any historical results will continue.
 
Yield of the Money Market Fund. The Money Market Fund calculates a seven-day
"current yield" (eight days when the seventh prior day has no net asset value
because the Investment Company is closed on that day) based on a hypothetical
shareholder account containing one share at the beginning of the seven-day
period. The return is calculated for the period by determining the net change
in the hypothetical account's value for the period, excluding capital changes.
The net change is divided by the share value at the beginning of the period to
give the base period return. This base period return is then multiplied by
365/7 to annualize the yield figure, which is carried to the nearest one-
hundredth of one percent.
 
Realized capital gains or losses and unrealized appreciation or depreciation
of the assets of the Money Market Fund are included in the hypothetical
account for the beginning of the period but changes during the period are not
included in the value for the end of the period. Values also reflect asset
charges (for advisory fees) as well as brokerage fees and other expenses.
 
Current yields will fluctuate daily. Accordingly, yields for any given seven-
day period do not necessarily represent future results. It should be
remembered that yield depends on the type, quality, maturities and rates of
return of the Money Market Fund's investments, among other factors. The Money
Market Fund yield does not reflect the cost of insurance and other insurance
company separate account charges. It also should not be compared to the yield
of money market funds made available to the general public because they may
use a different method to calculate yield. In addition, their yields are
usually calculated on the basis of a constant one dollar price per share and
they pay out earnings and dividends which accrue on a daily basis.
 
The following is an example of the calculation of the Money Market Fund's
yield for the seven-day period ended December 31, 1995. Yields may fluctuate
substantially from the example shown.
  1. Value for December 26, 1995
  2. Value for December 26, 1995 (exclusive of capital changes)
  3. Net change equals Line 1 subtracted from Line 2
  4. Base period return equals Line 3 divided by Line 1
  5. Current yield equals Line 4 annualized (multiplied by 365/8)
 
Calculation of Total Return and Average Annual Total Return. Total Return with
respect to the shares of a Fund is a measure of the change in value of an
investment in a Fund over the period covered, which assumes that any dividends
or capital gains distributions are reinvested in that Fund's shares
immediately rather than paid to the investor in cash. The formula for Total
Return with respect to a Fund's shares used herein includes four steps: (1)
adding to the total number of shares purchased by a hypothetical $1,000
investment the number of shares which would have been purchased if all
dividends and distributions paid or distributed during the period had been
immediately reinvested; (2) calculating the value of the hypothetical initial
investment of $1,000 as of the end of the period by multiplying the total
number of shares on the last trading day of the period by the net asset value
per share on the last trading day of the period; (3) assuming redemption at
the end of the period; and (4) dividing this account value for the
hypothetical investor by the initial $1,000 investment. Average Annual Total
Return is measured by annualizing Total Return over the period.
 
                                    SAI-12
<PAGE>
 
Yield of the Bond Funds. Yield of the shares of the Bond Funds will be
computed by annualizing net investment income, as determined by the
Commission's formula, calculated on a per share basis, for a recent one-month
or 30-day period and dividing that amount by the net asset value per share of
the Fund on the last trading day of that period. Net investment income will
reflect amortization of any market value premium or discount of fixed income
securities (except for obligations backed by mortgages or other assets) over
such period and may include recognition of a pro rata portion of the stated
dividend rate of dividend paying portfolio securities. The Yield of the Fund
will vary from time to time depending upon market conditions, the composition
of the portfolio and operating expenses allocated to the Fund.
 
Performance Comparisons. Each Fund may from time to time include the Total
Return, the Average Annual Total Return and Yield of its shares in
advertisements or in information furnished to shareholders. The Money Market
Fund may also from time to time include the Yield and Effective Yield of its
shares in information furnished to shareholders. Any statements of a Fund's
performance will also disclose the performance of the respective separate
account issuing the Contracts.
 
Each Fund may from time to time also include the ranking of its performance
figures relative to such figures for groups of mutual funds categorized by
Lipper Analytical Services ("Lipper") as having the same or similar investment
objectives or by similar services that monitor the performance of mutual
funds. Each Fund may also from time to time compare its performance to average
mutual fund performance figures compiled by Lipper in Lipper Performance
Analysis. Advertisements or information furnished to present shareholders or
prospective investors may also include evaluations of a Fund published by
nationally recognized ranking services and by financial publications that are
nationally recognized such as Barron's, Business Week, CDA Technologies, Inc.,
Changing Times, Dow Jones Industrial Average, Financial Planning, Financial
World, Forbes, Fortune, Hulbert's Financial Digest, Institutional Investor,
Investors Daily, Money, Morningstar Mutual Funds, The New York Times,
Stanger's Investment Adviser, Value Line, The Wall Street Journal,
Wiesenberger Investment Company Service and USA Today.
 
The performance figures described above may also be used to compare the
performance of a Fund's shares against certain widely recognized standards or
indices for stock and bond market performance.
 
The Standard & Poor's Composite Index of 500 Stocks (the "S&P 500 Index") is a
market value-weighted and unmanaged index showing the changes in the aggregate
market value of 500 stocks relative to the base period 1941-43. The S&P 500
Index is composed almost entirely of common stocks of companies listed on the
NYSE, although the common stocks of a few companies listed on the American
Stock Exchange or traded OTC are included. The 500 companies represented
include 400 industrial, 60 transportation and 50 financial services concerns.
The S&P 500 Index represents about 80% of the market value of all issues
traded on the NYSE.
 
The Lehman Brothers Government/Corporate Bond Index (the "Lehman
Government/Corporate Index") is a measure of the market value of approximately
5,300 bonds with a face value currently in excess of $1 million, which have at
least one year to maturity and are rated "Baa" or higher ("investment grade")
by a nationally recognized statistical rating agency.
 
The Salomon Brothers 1-3 Year Bond Index and Salomon Brothers 3-7 Year Bond
Index are comprised of the portion of the Salomon Brothers Broad Investment-
Grade Bond Index ("BIG Index") with the maturity indicated. The BIG Index
includes Treasury, Agency, mortgage and corporate securities. It is market-
capitalization weighted and includes all fixed-rate bonds with a maturity of
one year or longer and a minimum of $50 million amount outstanding at entry
which remain in the index until their amount falls below $25 million ($200
million for mortgage securities).
 
The Russell 2500 Index comprises the bottom 500 stocks in the Russell 1000
Index and all the stocks in the Russell 2000 Index and represents
approximately 11% of the total U.S. equity market capitalization. The largest
security in the index has a market value of roughly $1.3 billion.
 
The Wilshire Small Company Growth Index is composed of 1750 securities and
extends down to approximately the $100 million market capitalization level.
 
In reports or other communications to shareholders, the Investment Company may
also describe general economic and market conditions affecting the Funds and
may compare the performance of the Funds with (1) that of mutual funds
included in the rankings prepared by Lipper or similar investment services
that monitor the performance of insurance company separate accounts or mutual
funds, (2) IBC/Donoghue's Money Fund Report, (3) other appropriate indices of
investment securities and averages for peer universe of funds which are
described in this Statement of Additional Information, or (4) data developed
by the Adviser or any of the Subadvisers derived from such indices or
averages.

                     DESCRIPTION OF CORPORATE BOND RATINGS
 
Description of Corporate bond ratings of Moody's Investors Services, Inc.:
  Aaa--Bonds which are rated Aaa are judged to be of the best quality. They
  carry the smallest degree of investment risk and are generally referred to
  as "gilt-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 or
  fluctuation of protective elements may be of greater amplitude or there may
  be other elements present which make the long-term risks appear somewhat
  larger than in Aaa securities.
  A--Bonds which are rated A possess many favorable investment attributes and
  are to be considered as upper medium grade obligations. Factors giving
  security to principal and interest are considered adequate but elements may
  be present which suggest a susceptibility to impairment sometime in the
  future.
  Baa--Bonds which are rated Baa are considered as medium grade obligations,
  i.e., they are neither highly protected nor poorly secured. Interest
  payments and principal security appear adequate for the present but certain
  protective elements may be lacking or may be characteristically unreliable
  over any great length of time. Such bonds lack outstanding investment
  characteristics and in fact have speculative characteristics as well.
  Ba--Bonds which are rated Ba are judged to have speculative elements; their
  future cannot be considered as well assured. Often the protection of
  interest and principal payments may be very moderate and thereby not well
  safeguarded during 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.
  Caa--Bonds which are rated Caa are of poor standing. Such issues may be in
  default or there may be present elements of danger with respect to
  principal or interest.
  Ca--Bonds which are rated Ca represent obligations which are speculative in
  a high degree. Such issues are often in default or have other marked
  shortcomings.
  C--Bonds which are rated C are the lowest rated class of bonds and issues
  so rated can be regarded as having extremely poor prospects of ever
  attaining any real investment standing.
 
Moody's applies numerical modifiers, 1, 2 and 3 in each generic rating
classification from Aa through B in its corporate bond rating system. The
modifier 1 indicates that the security ranks in the higher end of its generic
rating category; the modifier 2 indicates a mid-range ranking; and the
modifier 3 indicates that the issue ranks in the lower end of its generic
rating category.
 
Description of corporate bond ratings of Standard & Poor's Corporation:
  AAA--Debt rated AAA has the highest rating assigned by Standard & Poor's.
  Capacity to pay interest and repay principal is very strong.
  AA--Debt rated AA has a very strong capacity to pay interest and repay
  principal and differs from the higher rated issues only in small degree.
  A--Debt rated A has a strong capacity to pay interest and repay principal,
  although it is somewhat more susceptible to the adverse effects of changes
  in circumstances and economic conditions than debt in higher rated
  categories.
  BBB--Debt rated BBB is regarded as having an adequate capacity to pay
  interest and repay principal. Whereas it normally exhibits adequate
  protection parameters, adverse economic conditions or changing
  circumstances are more likely to lead to a weakened capacity to pay
  interest and repay principal for debt in this category than in higher-rated
  categories.
  BB--B--CCC--CC--Debt rated BB, B, CCC and CC is regarded, on balance, as
  predominantly speculative with respect to the issuer's capacity to pay
  interest and repay principal in accordance with the terms of the
  obligation. BB indicates the lowest degree of speculation and CC the
  highest degree of speculation. While such debt will likely have some
  quality and protective characteristics, these are outweighed by large
  uncertainties or major risk exposures to adverse conditions.
  C--The rating C is reserved for income bonds on which no interest is being
  paid.
  D--Debt rated D is in default, and payment of interest and/or repayment of
  principal is in arrears.
 
Plus (+) or Minus (-): The ratings from "AA" to "BB" may be modified by the
addition of a plus or minus sign to show relative standing within the major
rating categories.

                   MUTUAL OF AMERICA INVESTMENT CORPORATION
 
  The economy continued to expand throughout 1995 although at a slower pace
than in 1994. However, investors in both the stock and bond market enjoyed one
of the most productive years in some time. The Dow Jones Industrial average
and the Standard & Poor's 500 Stock Index finished the year with increases of
36.6% and 37.5% respectively. The fixed income market responded across the
maturity spectrum with the yield curve ending 1995 much flatter than it began.
Long treasuries recorded the strongest performance while the broad market
averages returned over 19% for the year.
 
  In the first half of the year the Federal Reserve twice raised rates to
control inflation, but slow economic growth and low inflation resulted in two
rate reductions later in the year. Growth is expected to continue slowly in
the first half of 1996, gaining strength in the latter part of the year.
 
  The principal drivers of the markets' performance in 1995 are still
potential sources of market strength in 1996; a slowly growing economy, low
inflation, good corporate earnings and strong fund flows into mutual funds.
The stock market is expected to show continued strength throughout the year
with corrections occurring in response to disappointing news and the fixed
income market is expected to perform within a narrow trading range. The yield
curve may steepen if the Federal Reserve continues to use monetary policy to
stimulate economic growth. The market will be affected by national politics
including the Presidential election and the continuing budget impasse.
 
  We are pleased to provide you the Annual Report of the Mutual of America
Investment Corporation for the year ending December 31, 1995. Shown below are
the total return figures for each of the Funds of the Mutual of America
Investment Corporation.

                             THE MONEY MARKET FUND
 
  The investment objective of the Money Market Fund is the realization of high
current income to the extent consistent with the maintenance of liquidity,
investment quality and stability of capital. The Fund will invest only in
money market instruments and other short-term debt securities. The Fund
outperformed the Salomon Brothers 3-month Treasury Bill Index and the Donohue
Money Market Fund average yield for the last six months and all of 1995.
 
                             THE ALL AMERICA FUND
 
  The investment objective of approximately 60% of assets are to provide
investment results that to the extent practical correspond to the performance
of the Standard & Poor's 500 Composite Index (S&P 500).The investment
objective of the remaining assets is to achieve a high level of return by
means of a diversified portfolio. These assets are managed by three sub-
advisors and by Mutual of America Capital Management Corporation. The heavy
weighting of technology stocks by several of these portfolios contributed to
the Fund's being slightly behind the S&P 500 for the second half of the year,
as these stocks experienced some downward pressure late in the year. However,
total returns for the year were 36.6%, slightly ahead of the benchmark index
(80% S&P 500, 10% Wilshire Small Company Growth Index and 10% Russell 2000
Index) which returned 36.2%.

                                 THE BOND FUND
 
  This fund seeks a high level of return consistent with preservation of
capital through investment in publicly traded debt securities. The Fund's
return has been enhanced by its focus on corporate bonds which yield more than
comparable segments of the Lehman Brothers Corporate Bond Index. Additionally,
its average maturity is approximately 10% longer than the Index and this has
had a beneficial impact as rates have declined. For 1995 the Fund returned
19.4% vs 19.2% for the Index.

                           THE SHORT-TERM BOND FUND
 
  The Short-term Bond Fund maintains an average maturity between one and three
years. It's objectives are to achieve a high total return within this maturity
constraint and to maintain principal value. For 1995, the Fund returned 7.7%
vs 10.9% for the Salomon Brothers 1-3 Year Bond Index. The average life of
investments in the Fund is shorter than the Index and a move toward lower
rates caused the returns from longer issues in the Index to outperform the
assets in the Fund.

                            THE MID-TERM BOND FUND
 
  The average maturity of this Fund is between three and seven years.
Investment grade securities must be purchased with 80% of its assets and a
broad industry diversification is permitted. For 1995, the Fund achieved a
16.3% return, comparable to the Index. The Fund emphasized U.S. Treasury
securities due to the historically narrow spreads between corporates and
governments in its maturity range.

                              THE COMPOSITE FUND
 
  This is a balanced Fund which seeks to achieve a high level of total return
through appreciation of capital and current income. The proportion of assets
invested in each type of security varies depending on market conditions and
outlook. The stock and bond markets remained strong through the second half of
the year. The Standard & Poor's 500 returned 37.5%, its strongest performance
in years. The bond market, buoyed by sharply declining interest rates and
easing by the Federal Reserve, allowed the broad market averages to return
19.2% for the year. The total Fund returned 21.9% for the year, below the
benchmark index (50% S&P 500, 50% Lehman Brothers Government/Corporate) which
returned 28.4%.
 
  The equity portion of the Fund was behind the comparable index. The Fund's
value-oriented approach lead to an underweighting in technology stocks, which
were a major contributor to the stock market advance. In addition, a
conservative asset allocation in the first half of the year had a limiting
effect on the equity portion of the Fund.
 
  The bond portion of the Fund outperformed the benchmark index (Lehman
Brothers Government/Corporate Index) for the year. Bond returns were enhanced
by an emphasis on corporate bonds.

                          THE AGGRESSIVE EQUITY FUND
 
  The investment objective of the Fund is to aggressively manage an equity
portfolio which over time will outperform the broad market averages.
Approximately 50% of the Fund's assets are invested in an aggressive growth
manner and the other 50% in an aggressive value manner. The Fund's 38.2%
return exceeded the 37.5% return of the S&P 500 Index. Positive contributors
to performance included an emphasis on technology stocks which performed
strongly for most of the year, only experiencing a correction late in the
year, and favorable energy stock selection.

                   MUTUAL OF AMERICA INVESTMENT CORPORATION
                         NOTES TO FINANCIAL STATEMENTS
 
1. SIGNIFICANT ACCOUNTING POLICIES AND ORGANIZATION
 
  Mutual of America Investment Corporation (the "Investment Company") was
incorporated on February 21, 1986 under the laws of Maryland and is registered
under the Investment Company Act of 1940 as a diversified, open-end management
investment company. These financial statements reflect the Money Market, All
America (formerly Stock), Bond and Composite Funds as the respective
successors to Mutual of America Life Insurance Company's ("Mutual of America
Life") Separate Account No. 2 Money Market, Stock, Bond and Composite Funds.
Accordingly, the financial statements present the net assets of the Investment
Company at December 31, 1995, the results of its operations for the year then
ended and the changes in net assets for the years ended December 31, 1995 and
1994 of the Money Market, All America, Bond, and Composite Funds under the
continuing entity basis of accounting as if Separate Account No. 2's
investment assets and related liabilities had been invested in the Investment
Company since its inception. The succession or reorganization referred to
above was effected on October 31, 1986 by the exchange of shares of the
Investment Company for the respective net investment assets of Separate
Account No. 2 Funds. At the time of the exchange, the value of an Investment
Company share was established at an amount equal to the value of a respective
unit of Separate Account No. 2.
 
  On January 3, 1989, the net assets of Mutual of America Life's Separate
Account No. 1, available only for qualified pension plans, were invested in
the All America (formerly Stock) Fund of the Investment Company. Pursuant to
this transaction, approximately 249 million shares of the All America Fund
were issued.
 
  Effective February 5, 1993, the Equity Index Fund, Short-Term Bond Fund and
the Mid-Term Bond Fund commenced operations. On May 2, 1994 the Mutual of
America Aggressive Equity Fund commenced operations and the Stock Fund was
renamed the All America Fund with different investment objectives.
 
  The Investment Company currently sells shares of its eight series of funds
only to the separate accounts of Mutual of America Life and The American Life
Insurance Company of New York ("American Life"), an indirect, wholly-owned
subsidiary of Mutual of America Life, as a funding medium for variable annuity
and variable life insurance contracts issued by these companies. As of
December 31, 1995, Mutual of America Life owned 99.3% and American Life owned
0.7% of the Investment Company's outstanding shares.
 
  The following is a summary of the significant accounting policies of the
Investment Company:
 
  Security Valuation -- Investment securities are valued as follows:
 
    Stocks listed on national security exchanges and certain over-the-counter
  issues quoted on the National Association of Securities Dealers Automated
  Quotation ("NASDAQ") system are valued at the last sale price, or if no
  sale, at the latest available bid price.
 
    Debt securities are valued at a composite fair market value "evaluated
  bid," which may be the last sale price. Securities for which market
  quotations are not readily available will be valued at fair value as
  determined in good faith by the Investment Adviser under the direction of
  the Board of Directors of the Investment Company.
 
    Short-term investments with a maturity of 60 days or less are valued at
  amortized cost, which approximates market value. Short-term debt
  securities, which mature in more than 60 days, are stated at market value.
 
    Options purchased by the Investment Company are included in the
  investment portfolio and valued at the latest sale or closing price.
  Premiums received by the Investment Company upon writing covered call
  options are included in the Investment Company's statement of assets and
  liabilities as an asset and an equivalent liability. The liability is
  adjusted daily to reflect the market value of the options written based on
  the latest sale or closing price. If an option expires, or if the
  Investment Company enters into a closing purchase transaction, the
  Investment Company realizes a gain or, if the cost of a closing purchase
  transaction exceeds the premium originally received, a loss, and the
  liability related to the option is extinguished. If an option is exercised,
  the proceeds of the sale of the underlying security are increased by the
  premium originally received when the option was written.
 
  Security Transactions -- Security transactions are recorded on the trade
date. Interest income is accrued as earned. Dividend income is recorded on the
ex-dividend date.
 
                                      41
<PAGE>
 
                   MUTUAL OF AMERICA INVESTMENT CORPORATION
                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
 
  Realized gains and losses on the sale of short and long-term debt securities
are computed on the basis of amortized cost at the time of sale. Realized
gains and losses on the sale of common and preferred stocks are based on the
identified cost basis of the security.
 
  Federal Income Taxes -- The Investment Company intends to comply with the
requirements of the Internal Revenue Code applicable to regulated investment
companies and to distribute substantially all of its taxable income to
shareholders. Therefore, no federal income tax provision is required.
 
2. EXPENSES
 
  The Investment Company has entered into an Investment Advisory Agreement
with Mutual of America Capital Management Corporation ("the Adviser"), an
indirect wholly-owned subsidiary of Mutual of America Life. For providing
investment management services to each of the Funds of the Investment Company,
the Adviser receives a fee calculated as a daily charge at the annual rate of
 .25% of the value of the net assets of the Money Market Fund, and .50% of the
value of the net assets of the All America Fund, Bond Fund, Short-Term Bond
Fund, Mid-Term Bond Fund and Composite Fund, .125% of the value of the net
assets of the Equity Index Fund, and .85% of the value of the net assets of
the Aggressive Equity Fund. Prior to November 3, 1993, Mutual of America Life
was the investment adviser to the Investment Company; Mutual of America Life's
obligations under the Agreement were assumed by the Adviser on that date.
 
  Under subadvisory agreements, the Adviser has delegated its investment
advisory responsibilities to such subadvisers, is responsible for providing
management services to the respective Funds and pays the subadvisors for their
investment advisory services.
 
  The Adviser voluntarily limits the expenses of each Fund, other than for
brokers' commissions, transfer taxes and other fees relating to portfolio
transactions, to the amount of the advisory fee paid by the Funds of the
Investment Company to the Adviser. The Adviser may discontinue this practice
at any time.
 
  Various funds of the Investment Company placed portfolio transactions
through a broker affiliated with the Adviser. The aggregate commissions paid
to this broker for the year was $79,289.

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
TO THE BOARD OF DIRECTORS AND SHAREHOLDERS
OF MUTUAL OF AMERICA INVESTMENT CORPORATION:
 
  We have audited the accompanying statement of assets and liabilities,
including the portfolio of investments in securities, of Mutual of America
Investment Corporation (a Maryland Corporation) comprising, respectively, the
Money Market, All America (formerly the Stock Fund), Equity Index, Bond,
Short-Term Bond, Mid-Term Bond and Composite Fund as of December 31, 1995, and
the related statement of operations for the year then ended and the statements
of changes in net assets for each of the two years in the period then ended,
and the financial highlights for each of the four years in the period then
ended. We have also audited the statement of assets and liabilities, including
the portfolio of investments in securities, of Mutual of America Investment
Corporation comprising the Aggressive Equity Fund as of December 31, 1995 and
the related statements of operations for the year then ended and the statement
of changes in net assets and the financial highlights for the year ended
December 31, 1995 and the period May 2, 1994 (commencement of operations) to
December 31, 1994. These financial statements and the financial highlights are
the responsibility of the Corporation's management. Our responsibility is to
express an opinion on these financial statements and financial highlights
based on our audits. The financial highlights of Mutual of America Investment
Corporation for each of the six years in the period ended December 31, 1991,
were audited by other auditors whose report dated February 19, 1992, expressed
an unqualified opinion on those financial highlights.
 
  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 confirmations of securities
owned as of December 31, 1995 by correspondence with the custodian. An audit
also included 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
the Money Market, All America (formerly the Stock Fund), Equity Index, Bond,
Short-Term Bond, Mid-Term Bond, and the Composite Funds of Mutual of America
Investment Corporation as of December 31, 1995, the results of their
operations for the year then ended and the changes in their net assets for
each of the two years in the period then ended and their financial highlights
for each of the four years in the period then ended in conformity with
generally accepted accounting principles. Also, in our opinion, the financial
statements referred to above present fairly, in all material respects, the
financial position of the Aggressive Equity Fund of Mutual of America
Investment Corporation as of December 31, 1995, the results of its operations
for the year then ended and the changes in its net assets and its financial
highlights for the year ended December 31, 1995 and the period May 2, 1994
(commencement of operations) to December 31, 1994 in conformity with generally
accepted accounting principles.
