                   MUTUAL OF AMERICA INVESTMENT CORPORATION
 
  We are pleased to report that the results for 1996 for the funds offered by
the Mutual of America Investment Corporation were, overall, quite positive.
 
  Over the past year, the U.S. economy grew at a moderate pace, while
inflation remained low and unemployment stayed steady at around 5.5%. The
continuing infusion of cash into the equity markets saw the Dow Jones
Industrial Average (up 28% for the year) and the Standard & Poor's 500 Stock
Index (with a gain of nearly 23% for 1996) reach record highs. In the debt
markets, short-term rates stayed fairly steady throughout the year, although
long bond rates rose nearly 75 basis points.
 
  For 1997, the economy is expected to continue to grow, while estimates are
that inflation will hover around the 3% level. Competitive pressures continue
to be strong with low unemployment and with producers continuing to absorb
higher cost.
 
  Shown below are the total return figures for each Fund of the Mutual of
America Investment Corporation.

                               MONEY MARKET FUND
 
  The Money Market Fund returned 5.3% for 1996, matching the Salomon Brothers
three-month Treasury Bill Index return. The seven-day annualized yield as of
12/31/96 was 5.36%.
 
                                ALL AMERICA FUND
 
  The investment objective of approximately 60% of this Fund's assets is to
provide investment results that, to the extent practical, correspond to the
performance of the Standard & Poor's 500 Composite Index of 500 Stocks. 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.
 
  For the year ended December 31, the Fund returned 20.7% compared to the S&P
of 23.0%.

* Beginning with the Fund's 1997 financial statements, the Blended Index will no
  longer be used for comparative purposes. The Fund has determined that the 
  S & P 500 index is more standard performance index that wil facilitate an
  investor's evaluation of the Fund's performance.

                               EQUITY INDEX FUND
 
  For the year ended December 31, 1996, the Equity Index Fund returned 22.7%.
This approximates the return from the S&P 500 Index. (Please note that the S&P
500 is not subject to the fees and expenses that the Equity Index Fund must
pay.) As of June 30th, Morningstar, the mutual fund rating service, increased
the rating of our fund from four stars to five stars, Morningstar's highest
rating.
 
  The main contributors to performance in 1996 included semi-conductor,
footwear, financial, and oil and gas drilling stocks. All of these groups did
sharply better than the index. Subperformance was shown by steel, health care,
home building and trucking stocks--all of these groups had negative returns.

                                   BOND FUND
 
  The Bond 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 Government/Corporate Bond Index.
For 1996, the Fund returned 3.5% versus the Index return of 2.9%.

                              MID-TERM BOND FUND
 
  The average maturity of this Fund will be between three and seven years.
Investment grade securities must be purchased with 80% of its assets and a
broad industry diversification is permitted. The Fund emphasized U.S. Treasury
securities due to the historically narrow spreads between corporate debt
securities and government debt securities in its maturity range. The Fund
returned 3.9% for 1996 matching the Salomon Brothers 3-7 year Index return of
3.9%.

                                COMPOSITE FUND
 
  The Composite Fund returned 11.9% for 1996, compared to a blended index
(stocks, bonds/Treasury Bills) return of 13.0%. The equity portion of the Fund
increased by 20.5% for the year, compared to a total return for the S&P 500 of
23%. The bond portion of the fund increased by 4.1% for the year, compared to
a 2.9% return for the Lehman Brothers Government/Corporate Index. The asset
allocation remains approximately the same since August when it was changed to
50% stocks, 35% bonds, and 15% money market instruments. Strong performance in
energy-related and transportation stocks was partially offset by poor
performance in technology and consumer staple-related issues.

* Beginning with the Fund's 1997 financial statements, this blended index will
  no longer be used. The Fund has determined that the S & P 500 Index and the
  Lehman Brothers Government/Corporate Bond Index and the 90 - day Treasury Bill
  rate, shown separately, would be more appropriate in evaluating the Fund's
  performance based on the types of securities in which it invests.

1. SIGNIFICANT ACCOUNTING POLICIES AND ORGANIZATION
 
  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"). As a "series" type mutual fund, the Investment Company
issues separate classes (or series) of capital 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. The Investment Company is a successor to Mutual of
America Life's Separate Account No. 2 Money Market, All America (formerly
stock) Bond and Composite Funds having exchanged its shares for the respective
net assets of these Separate Account No. 2 Funds in 1986.
 
  The Investment Company shares are sold only to Mutual of America Life and
American Life for allocation to their Separate Accounts as a funding medium
for variable annuity and variable life insurance contracts issued by these
companies. As of December 31, 1996 Mutual of America Life owned 98.4% and
American Life 1.6% of the Investment Company's aggregate outstanding shares.
 
  In January 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 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 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.
 
    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.
 
    The Fund may purchase stock index futures contracts for cash management
     purposes to remain more fully invested in the equity markets while
     minimizing transaction costs. Initial cash margin deposits (represented
     by cash or Treasury bills) are made upon entering into futures
     contracts. (This initial margin, equal to approximately 3% of the
     contract amount, does not involve the borrowing of funds to finance the
     transaction). During the period the futures contract is outstanding,
     changes in the value of the contract are recognized as unrealized gains
     or losses from futures transactions by "marking-to-market" on a daily
     basis to reflect the market value of the contract at
 
                                      50
<PAGE>
 
                   MUTUAL OF AMERICA INVESTMENT CORPORATION
                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
     the end of each trading day. Depending upon whether unrealized gains or
     losses are incurred, variation margin payments are received or made.
     When the contract is closed, a realized gain or loss from futures
     transactions is recorded, equal to the net variation margin received or
     paid over the period of the contract. The "Underlying Face Amount at
     Value" representing the aggregate of outstanding contractual amounts
     under futures contracts reflects the extent of a Fund's exposure to off-
     balance sheet risk.
 
    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. Foreign source tax withheld from dividends is
     recorded as a reduction from dividend income. Should reclamation efforts
     succeed, such amounts are recorded as income upon collection.
 
    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 stock is based on the
     identified cost basis of the security, determined on the first-in,
     first-out ("FIFO") basis.
 
    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.
 
  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 ended December 31, 1996 was $100,812 or 8% of
total commissions. In addition, a Sub-Advisor of the Fund placed a portion of
its portfolio transactions with its affiliated broker-dealer. Such commissions
amounted to $72,555 or 6% of the Fund's total commissions.

                   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, Composite, and Aggressive Equity Funds as of
December 31, 1996, 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 five years
in the period then ended. 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.
 
  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, 1996 by correspondence with the custodian. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, the financial statements and financial highlights referred
to above present fairly, in all material respects, the financial position of
the Money Market, All America (formerly the Stock Fund), Equity Index, Bond,
Short-Term Bond, Mid-Term Bond, Composite, and Aggressive Equity Funds of
Mutual of America Investment Corporation as of December 31, 1996, 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 five years in the period then ended in conformity
with generally accepted accounting principles.
