MUTUAL OF AMERICA INVESTMENT CORPORATION

We are pleased to present the Mutual of America Investment Corporation (the "Investment Company") Annual Report. This Report includes important information regarding the performance and financial positions of the Investment Company's funds for the year ended December 31, 2009.

2009: Financial Markets Take Off

After plummeting 25% during the first two months of 2009, and 56% from its October 2007 peak, the S&P 500^® advanced more than 50% through the remainder of last year for a full year total return of 26.46%. Most other equity markets around the world followed a similar pattern, although the magnitude of the advances from the market lows set in early March varied. Developed nations' (Europe, Japan, and the U.S.) stock markets were up for the year in the 20% to 30% range, while stock markets in developing nations, such as China, Brazil, Russia, India, Indonesia, and Korea, were up in the range of 50% to over 100%.

Corporate bonds, both investment grade and so-called "junk" bonds, also traced out a pattern similar to equities, as prices initially plummeted and yields rose through early March, and then reversed dramatically for the rest of the year. In the U.S., the corporate bond component of the Barclay's Capital Aggregate Index generated an 18.68% return for the year, its best return in 14 years. And the Barclay's Capital High Yield ("junk" bonds) index was up over 58% for the year, comparable to some of the developing nations' equity markets. Similarly, bond markets in developing nations advanced 34% in dollar terms for the year according to Barclay's Capital Emerging Market Index.

U.S. Treasuries, and sovereign bonds of developed nations in general, fared poorly in 2009 relative to other asset classes. High prices and low rates established in the depths of panic in late 2008 and early 2009 gave way to a greater willingness to take risk in equities and corporate bonds. In addition, concern about rising government deficits raised fears of inflation, encouraging the sale of longer term (3 to 30 years) government securities, which pushed yields up and prices and returns down.

Investors Step Back In ... Cautiously

Very few investors anticipated the magnitude of returns realized in 2009, especially early in the year. There are two market adages that seem apt as an explanation of this dramatic performance: "Don't fight the Federal Reserve" and "markets always climb a wall of worry."

In retrospect, the market takeoff from the March lows seems to have been ignited by a collective conclusion among investors that the unprecedented monetary and fiscal stimulus launched by the central banks and fiscal authorities around the world had helped prevent a total collapse of the global financial system and descent into global economic depression. In short, the world was too big and too important to fail.

In particular, the global banking system had to be preserved at all costs. Two key events took place in early 2009 that gave investors confidence that their worst fears would not be realized. First, there was the decision in late February/early March by U.S. authorities to not formally nationalize the U.S. banking system. This was followed by the Accounting Standards Board's clarification of the requirement that banks write down the value of toxic assets held on their balance sheets to market values.

With stock prices and valuations compressed to levels not seen since the late 1970s, and central banks promising liquidity support for an extended period, investors embraced greater risk by pouring money into stocks and bonds. Thus, "don't fight the Fed."

Consumers Face Numerous Challenges

However, the belief that the world was not coming to an end did not mean that the global economy was still not in deep trouble. Global trade had imploded, Gross Domestic Product (GDP) growth was down in all developed nations and slowed significantly in key developing countries, unemployment was rising everywhere, and lending came to a virtual halt.

In the United States, the residential housing industry, whose collapse sparked the financial and economic crisis, remained mired in recession, with delinquencies and foreclosures rising, housing prices continuing to fall, and housing starts and sales still declining after two years. Consumers were not spending because they had lost, or were afraid they were going to lose, their jobs and/or houses. Moreover, in general, they carried high debt loads, including mortgages and credit card debt. The commercial real estate market was also entering a downturn in delayed response to the economic slowdown and rising unemployment. In early April 2009, U.S. first quarter GDP was reported to have declined 6.4% on an annualized basis from the previous quarter. That followed declines of 5.4% in

1

the fourth quarter and 2.7% in the third quarter of 2008, respectively. Yet, markets continued their powerful advance. Thus, "markets climb a wall of worry."

Dire Outlook Begins to Lift

While the economic data through the spring and into summer of 2009 continued to be dire, there were increasing hints that the news was becoming "less bad." As noted in our publications on several occasions, markets tend to react less to what is going on at the moment and more to attempts to assess prospects in the future. The markets' behavior suggested that the global economy would soon begin to recover and grow again.

Corporate profit numbers, while still registering declines for the second and third quarters on a year-over-year basis, came in well ahead of expectations, supporting the notion that things were not as bad as previously thought and possibly were improving at an accelerating pace. Admittedly, these results were largely driven by severe cost-cutting measures, including layoffs, curtailed capital expenditures, inventory reductions, and even delayed payment of bills. Furthermore, revenues continued to fall, although, similar to profits, at a decelerating rate. Nonetheless, the market interpreted "not as bad as expected" in a positive light and continued to advance.

Similarly, in mid-October 2009, U.S. GDP was reported to have grown on an annualized basis for the first time in a year, registering an advance of 3.7% in the preliminary release. This number was ultimately revised down to 2.2%, but was still the first increase in four quarters. It is positive information such as this that sustains market rallies because economists respond by raising their GDP estimates and analysts become more aggressive in raising their earnings estimates.

This is exactly what happened during the last few months of 2009. U.S. economic data releases during this time frame were generally on the positive side. Production and trade showed improvement, inventories were scaled down to the level of current sales, inflation was well contained, and even home sales and retail sales showed unanticipated strength as the year drew to a close. Data from developing nations such as China, India, and Brazil, and resource-rich nations such as Australia and Canada, showed even more powerful signs of recovery, providing potential impetus to a U.S. recovery through the trade accounts.

Self-sustaining Recovery Still at Bay

However, several fundamental problems continue to undermine the potential for a strong, self-sustaining recovery in the U.S. First, unemployment remains very high, at 10%. It is true that the rate of layoffs declined dramatically over the past six months, and November actually posted the first month of job additions after 22 consecutive months of job reductions. Nevertheless, most commentators do not expect corporations to begin hiring at a rapid pace, but rather anticipate any U.S. recovery to follow the "jobless recovery" blueprint of the last two post-recession periods. Because consumer spending represents two-thirds of the U.S. economy, weakness there almost guarantees sub-par GDP growth for an extended period of time.

Second, the residential housing market remains troubled, with delinquencies and foreclosures on the rise and most government efforts to improve the problem inadequate to date. A slow recovery in employment, and therefore consumer income, will remain a headwind to home sales for an extended period of time.

Third, while the banking industry has been "saved," Congress seems determined to implement a new regime of regulations and penalties which may adversely impact potential rates of return on bank capital and could lead to reduced lending by the banking industry to the business sector, especially smaller businesses. This consequence would appear to be opposite of what is desired.

Largely because of these issues, the Federal Reserve, and most other central banks around the world, have stated or implied that they will continue their accommodative monetary policies through very low short-term lending rates and the maintenance of a variety of other liquidity programs. At the same time, they have begun to unwind those programs that no longer seem necessary to support markets and are studying how to most effectively withdraw from the remaining emergency programs so that markets can begin to function on their own again.

Markets Likely Kept in Check in 2010

The key issue of debate among economists and strategists now is not if, but when, will the Federal Reserve begin to raise interest rates, and at what pace will their program of tightening be executed. Although the Fed did raise the discount rate 0.25% on February 18, 2010, it has not indicated when and by how much it will raise the more important target Fed funds rate. In fact, at that time the Fed confirmed its expectation that the Fed funds rate will remain exceptionally low for "an extended period." This will remain an important uncertainty until the Fed acts. Current thinking on when this will occur ranges from as early as this June to not before mid- to late-2011.

2

The variables that will likely determine any Fed action will be the progress of economic recovery, especially job creation, as well as the behavior of inflation and inflation expectations over the short term. We think that job creation will remain tepid for a long time and inflation will remain well contained, largely because of wage cost control; and therefore, a rate-raising cycle by the Fed will likely be deferred until, at the earliest, late this year.

Given that scenario, and the uncertainties attached to it, as well as the magnitude of stock and corporate bond price advances witnessed over the past ten months, we believe that markets will generate much more modest returns in 2010 than in 2009. There also exists the possibility of a substantial correction along the way as fear emerges over the sustainability of recovery; concern about how rising interest rates might affect any recovery that has taken hold; and longer-term concerns over rising federal deficits, rising corporate and individual taxes, and the inflationary implications of both.

EQUITY INDEX FUND

The Equity Index Fund's objective is to replicate the performance of the S&P 500^® Index (the "S&P 500"), which consists of 500 stocks chosen by Standard & Poor's for market size, liquidity and industry group representation. The S&P 500 is a market-weighted index of 500 stocks traded on the New York Stock Exchange, American Stock Exchange and Nasdaq, with each stock's weight in the index proportionate to its market value. The weightings make each company's influence on the S&P 500's performance directly proportional to that company's market value.

The S&P 500 ended 2009 up 26.46%, after being down 24.34% in the first two months of the year. The market was able to rebound over 63% from the March 6th low of 676, closing at a level of 1,159 on December 31, 2009. The financial sector rebounded over 140%, and the Consumer Discretionary, Technology, Industrials and Material sectors followed closely with total returns above 80% for the same time period. Although the year began with doom, March began a trend up for the remainder of the year. The second and third quarters both were up over 15%. The month of October was the only negative return for the second half of the year. Although the pace slowed going into the fourth quarter, the market was still up over 6%.

The Equity Index Fund's performance for the year ended December 31, 2009, was 26.13%, in line with the benchmark return of 26.46%. Note that the Equity Index Fund's performance includes expenses, such as transaction costs and management fees, which are not applicable to the benchmark.

ALL AMERICA FUND

The investment objective of the All America Fund is to outperform the S&P 500^® Index (the "S&P 500"). The All America Fund is approximately 60% invested in the 500 stocks that comprise the S&P 500, with the remaining 40% actively managed, using three different investment approaches. The actively managed portion of the All America Fund is close to being equally distributed between Large Cap stocks and Small Cap stocks, with the Small Cap stocks in turn equally distributed between Small Cap Value and Small Cap Growth stocks.

For the full year 2009, the S&P 500^® Index of large capitalization stocks advanced by 26.46% on a total return basis, while the Russell 2000^® Growth Index was up 34.47% and the Russell 2000^® Value Index was up 20.58%.

The All America Fund's return for the year ended December 31, 2009, was 25.31% versus the benchmark return of 26.46%. The underperformance was attributable entirely to the underperformance of the actively managed Large Cap portion of the Fund, representing 20% of total assets. The indexed portion of the Fund, representing 60% of the overall portfolio, modestly outperformed the S&P 500, while the Small Cap Growth and Small Cap Value portions of the Fund, each representing 10% of total assets, both handsomely outperformed the S&P 500.

SMALL CAP VALUE FUND

The investment objective of the Small Cap Value Fund is to outperform the Russell 2000^® Value Index. The Small Cap Value Fund generally invests in companies that are below $3 billion in market capitalization and have lower price-to-book characteristics than the overall market.

For the year ended December 31, 2009, the Small Cap Value Fund returned 29.28% versus a 20.58% return for the Russell 2000^® Value Index. Stock selection was the primary driver of positive performance versus the benchmark. Sectors contributing to Fund performance included Finance, Basic Materials and Healthcare, while sectors detracting from Fund performance included Energy and Technology.

SMALL CAP GROWTH FUND

The investment objective of the Small Cap Growth Fund is capital appreciation. The Small Cap Growth Fund invests in growth stocks within the small capitalization marketplace. The Fund returned 27.69% during the year ended December 31, 2009. The Fund's benchmark, the Russell 2000^® Growth Index, returned 34.47% for the period.

The Small Cap Growth Fund's underperformance against its benchmark was partially due to its lack of exposure to the micro-cap sector of the small capitalization marketplace. The best performing stocks were those that had the highest levels of volatility and beta. Additionally, single-digit-priced stock, more specifically those under $5, had some of the biggest price moves. Macroeconomic factors and the re-pricing of risk propelled the equity marketplace in 2009. The Healthcare and Industrial sectors underperformed the benchmark and our stock selection also detracted from these two areas for the calendar year. Energy and Telecommunication Services were our two best performing sectors, which benefited from stock selection. In sum, we remained focused on bottom-up stock selection in a year where fundamental investing was not in style.

MID CAP VALUE FUND

The investment objective of the Mid Cap Value Fund is to outperform the Russell Midcap^® Value Index. The Mid Cap Value Fund generally invests in companies that are between $1 billion and $20 billion in market capitalization and have lower price-to-book characteristics.

For the year ended December 31, 2009, the Mid Cap Value Fund returned 25.22% versus a 34.21% return for the Russell Midcap^® Value Index. Adverse stock selection was the primary driver of negative performance versus the benchmark. Sectors contributing to Mid Cap Value Fund performance included Utilities and REITs while sectors detracting from Mid Cap Value Fund performance included Industrial and Retail.

MID-CAP EQUITY INDEX FUND

The Mid-Cap Equity Index Fund invests in the 400 stocks that comprise the S&P MidCap 400^® Index (the "S&P MidCap 400"). The S&P MidCap 400 is a market-weighted index of 400 stocks traded on the New York Stock Exchange, American Stock Exchange and Nasdaq. The weightings make each company's influence on the S&P MidCap 400's performance directly proportional to that company's market value. The companies included in the S&P MidCap 400 tend to be typical of this asset class, the medium-capitalized sector of the U.S. securities market.

The S&P MidCap 400 once again outperformed both the S&P 500^® Index and the S&P 600^® Index (small cap) during 2009 with a total return of 37.38%. The S&P MidCap 400 recovered over 78% from its March 6th low, continuing the strong upward trend through the remainder of the year. The Materials and Energy sectors were up over 100% as metal and oil prices reached new highs. Financials rebounded over 85% ending the full year up over 13%. The market continues to climb higher into 2010 toward the 900 level seen in 2007.

The Mid-Cap Equity Index Fund's performance for the year ended December 31, 2009, was 36.69%, below the 37.38% return of the S&P MidCap 400. Note that the performance of the Mid-Cap Equity Index Fund includes expenses, such as transaction costs and management fees, which are not applicable to the benchmark. Gross of fees, the total return of the account was 37.05%. The underperformance was attributable to the higher volatility of the account due to the use of future contracts to hedge temporary cash positions.

INTERNATIONAL FUND

The International Fund seeks capital appreciation by investing, directly or indirectly, in stocks of companies located outside of the United States that are reflected or contained in the Morgan Stanley Capital International, Inc. Europe, Australasia and Far East^® Index (MSCI EAFE^® Index). Currently the International Fund is invested exclusively in exchange traded funds that reflect or closely match the holdings in the MSCI EAFE^® Index.

Performance for the International Fund is compared to the MSCI EAFE^® Index. For the year ended December 31, 2009, the International Fund returned 25.22%, underperforming the 32.46% return of the benchmark. The Fund's cash position continued to create a drag on performance in the second and third quarters of 2009 as a result of the very strong performance of the International markets. During that six-month period the MSCI EAFE^® Index rose 50%, while the Fund grew 47%.

COMPOSITE FUND

The Composite Fund invests in a diversified portfolio of common stocks and fixed-income securities, seeking appreciation and current income. The equity portion of the Composite Fund invests in stocks within the S&P 500^® Index.

For the year ended December 31, 2009, the equity portion of the Fund had a total return of 20.44% (before expenses), underperforming the S&P 500^® Index by 602 basis points. The equity portion of the Composite Fund maintains sector weights within plus or minus 100 basis points of the S&P 500^® Index and does not take positions in individual stocks with overweights of more than 200 basis points. This structural discipline produces a relatively low-risk portfolio that emphasizes stock selection based on strong fundamental analysis.

However, 2009 was a particularly difficult time for the type of conservative stock selection employed by the Fund. The strong stock market rally from the lows of early March was driven largely by stocks with characteristics far different from those the Fund normally seeks out. Specifically, the market gravitated toward lower quality, higher risk stocks characterized by small market capitalizations, high volatility, high leverage, low price and low returns on equity. These are generally the types of stocks the Fund attempts to avoid, as it did in 2009 to the detriment of performance over that time frame. Nevertheless, this philosophy of investment has served our clients well over the longer term. We began to see signs that the market is normalizing in late 2009 and early 2010, which should bode well for better performance in the current year.

The bond market remained focused on income as the Federal Reserve promoted low interest rates, especially in the money markets. As a result, higher yielding corporate bonds were in great demand. The risk premium attached to corporate credits diminished with each passing month, both as a result of enthusiasm about economic prospects and a lack of supply of new issues.

The Fund's strategy is to maintain a diversified portfolio of higher yielding corporate bonds while keeping its duration slightly short in order to guard against incipient inflation. This focus on income, rather than market volatility, enables the Fund to provide favorable compounded rates of return over meaningful time periods.

For the year ended December 31, 2009, the Composite Fund returned 18.45% (after expenses) compared to the weighted benchmark return of 18.25%, 40% of which is based on the Barclays Capital Aggregate Bond Index and 60% of which is based on the S&P 500^® Index. The outperformance of the fixed-income portion of the Composite Fund more than offset the underperformance of the equity portion, despite its significantly lower proportion of the Fund overall.

CONSERVATIVE ALLOCATION FUND

The objective of the Conservative Allocation Fund is current income and, to a lesser extent, capital appreciation. The Conservative Allocation Fund invests primarily in the fixed-income funds of the Investment Company and also invests in an equity fund of the Investment Company. The Conservative Allocation Fund's target allocation is approximately 75% of net assets in fixed-income funds (approximately 30% in the Bond Fund and approximately 45% in the Mid-Term Bond Fund) and approximately 25% of net assets in equity funds (the Equity Index Fund).

Performance for the Conservative Allocation Fund is compared to the Barclays Capital Aggregate Bond Index (75% weighting) and the S&P 500^® Index (25% weighting). For the year ended December 31, 2009, the Conservative Allocation Fund returned 15.94% versus an 11.06% return in the weighted benchmark. The outperformance of the Fund is mainly attributable to the Bond Fund and the Mid-Term Bond Fund outperforming the Barclays Capital Aggregate Bond Index.

MONEY MARKET FUND

The Money Market Fund's investment objective is to realize current income while maintaining liquidity, investment quality and stability of capital through investing in high-quality commercial paper issued by U.S. corporations and securities issued by the U.S. government and its agencies. The Money Market Fund returned -0.08% for the year ended December 31, 2009, compared to a 0.16% return for the Citigroup 3-Month Treasury Bill Index. Note that the performance of the Money Market Fund includes expenses, such as transaction costs and management fees, which are not applicable to the benchmark.

The 2009 money market was characterized by extremely low interest rates and shrinking supply of eligible investments. The Federal Funds target rate remained at a historically low range of 0 to 25 basis points throughout the course of 2009 and is expected to persist in 2010. At the December 16th meeting, the Fed indicated that it will continue to keep rates "exceptionally low" for "an extended period."

The seven-day effective yield as of February 16, 2010, was -0.21%. As with all performance reporting, this yield is not necessarily indicative of future annual yields. Neither the Federal Deposit Insurance Corporation nor any other U.S. government agency insures or guarantees the Separate Account's investments in shares of the Money Market Fund.

MID-TERM BOND FUND

The Mid-Term Bond Fund seeks a high level of return consistent with the preservation of capital through investment in publicly traded debt securities. The Mid-Term Bond Fund primarily invests in corporate and U.S. government agency securities, which normally yield more than U.S. Treasury issues.

The Mid-Term Bond Fund continued to overweight corporate issues and underweight Agencies and Treasuries during 2009. Agencies have been used as a source of funds and will continue to be sold as better opportunities in corporate bonds become available. The Mid-Term Bond Fund also maintains extreme diversification in its credit exposure in order to minimize event risk.

The Fund's duration is 90% of its market benchmark. This results in lower price volatility and protects against the effects of prospective inflation. While inflation is not a current problem, the government economic stimulus and debt monetization policies will cause an eventual rise in rates.

For the year ended December 31, 2009, the Mid-Term Bond Fund returned 11.22% versus a 5.89% return for the Citigroup Government/Corporate 3-7 Year Bond Index. The Mid-Term Bond Fund's emphasis on higher-yielding corporate issues was a major contributor to outperformance.

BOND FUND

The Bond Fund's primary investment objective is to provide as high a level of current income over time as is believed to be consistent with prudent investment risk by investing primarily in investment grade, publicly traded debt securities. A secondary objective is preservation of capital. The Bond Fund primarily invests in corporate, U.S. government agency and mortgage-backed securities, all of which normally yield more than U.S. Treasury issues.

The Federal Reserve continued to keep short-term rates very low during 2009 in order to try and stimulate the economy and reliquify the banking system. Other rates along the treasury yield curve maintained a steep configuration as the Federal Reserve aggressively intervened on a regular basis to try and force rates down in order to subsidize the mortgage market.

The corporate bond market also continued its positive response to the various government stimulus programs. Yield spreads between government and corporate bonds compressed aggressively during the final six months of 2009 as market participants became enthusiastic about economic prospects in 2010.

The Bond Fund's strategy was to maintain a slightly shorter duration than its benchmark, emphasize relatively short corporate bonds with high yields, establish extreme credit diversification, and take a market weight in mortgage-related securities. So long as inflation is perceived as a long-term threat, this strategy will be maintained in the Bond Fund.

The Bond Fund's return for the year ended December 31, 2009, was 14.61%, compared to 5.93% for the Barclays Capital Aggregate Bond Index. The Fund's emphasis on higher-yielding corporate issues was a major contributor to outperformance.

MUTUAL OF AMERICA INVESTMENT CORPORATION
EXPENSE EXAMPLE

EXAMPLE

As a shareholder of one of the Mutual of America Investment Corporation Funds, you incur ongoing costs, including management fees and other Fund expenses. You do not incur transactional costs, such as sales charges (loads), redemption fees or exchange fees.

This Example is intended to help you understand your ongoing costs (in dollars) of investing in a Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The Example is based on an investment of $1,000 invested at July 1, 2009 and held for the entire period ending December 31, 2009.

ACTUAL EXPENSES

The first line of the tables below provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000=8.6), then multiply the result by the number in the first line under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the tables below provides information about hypothetical account values and hypothetical expenses based on each Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund with other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the second line of the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning other funds, which may also charge transactional costs, such as sales charges (loads), redemption fees or exchange fees.

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 principally offers its shares exclusively to separate accounts of Mutual of America Life Insurance Company ("Mutual of America Life") and its affiliates. 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. At December 31, 2009, there were 23 Funds (collectively, "the Funds"): Equity Index Fund, All America Fund, Small Cap Value Fund, Small Cap Growth Fund, Mid Cap Value Fund, Mid-Cap Equity Index Fund, International Fund, Composite Fund, Money Market Fund, Mid-Term Bon d Fund, Bond Fund; Retirement Income Fund, 2010 Retirement Fund, 2015 Retirement Fund, 2020 Retirement Fund, 2025 Retirement Fund, 2030 Retirement Fund, 2035 Retirement Fund, 2040 Retirement Fund and 2045 Retirement Fund (collectively, "Retirement Funds"); a Conservative Allocation Fund, a Moderate Allocation Fund and an Aggressive Allocation Fund (collectively "Allocation Funds"). The International Fund and the Retirement Funds began operations on November 5, 2007. The Small Cap Value Fund, Small Cap Growth Fund and the Mid Cap Value Fund began operations on July 1, 2005.

Investment Company shares are issued to Mutual of America Life, and on a limited basis, to Wilton Reassurance Life Company of New York (formerly The American Life Insurance Company of New York), for allocation to their Separate Accounts as a funding medium for variable accumulation annuity contracts and variable life insurance policies. In addition, shares of selected equity and fixed income funds of the Investment Company are directly issued to one or more of the Investment Company's Allocation Funds.

The preparation of financial statements in accordance with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, income, expenses and related disclosures. Actual results, however, may differ from those estimates.

The following is a summary of the significant accounting policies consistently followed by the Investment Company, which are in conformity with U.S. generally accepted accounting principles ("GAAP"):

Fair Value — The Investment Company values its investments at fair value. Fair value is an estimate of the price the Fund would receive upon selling a security in an orderly arms-length transaction. Investments are categorized based on a three-level valuation hierarchy for measurement and disclosure of fair value. The valuation hierarchy is based upon the transparency of inputs used to measure fair value. The three levels are as follows:

•  Level 1 — quoted prices in active markets for identical securities.

•  Level 2 — other significant observable inputs (including yield, quality, coupon rate, maturity, issue type, quoted prices for similar securities, prepayment speeds, trading characteristics, etc.).

•  Level 3 — significant unobservable inputs (including the Fund's own assumptions in determining the fair value of investments).

As of December 31, 2009, management determined that the fair value inputs for all equity securities, including shares of registered investment companies, were considered Level 1, with the exception of non-registered securities under Rule 144A of the Securities Act of 1933 which were considered Level 2. In addition, certain Rule 144A securities not actively traded were considered Level 3. Fair value inputs for all debt securities were considered Level 2. The inputs used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

In January 2010, the Financial Accounting Standards Board issued Accounting Standards Update ("ASU") No. 2010-06, "Improving Disclosures About Fair Value Measurements." The ASU clarifies existing disclosure regarding fair value measurements. Additionally, effective for interim and annual reporting periods beginning after December 15, 2009, the ASU requires entities to disclose significant transfers into and out of Level 1 and 2 fair value hierarchies and the reasons for those transfers. Effective for interim and annual reporting periods beginning after December 15, 2010, the ASU also requires entities to disclose information about purchases, sales, issuances and settlements of Level 3 securities on a gross basis, as opposed to the current net number. Management is currently evaluating the impa ct of ASU 2010-06 on the disclosures of fair value of the Funds' investments.

Security Valuation — Investment securities are carried at fair value as follows:

Exchange-traded equity securities are valued at the last sales price on the principal exchange on which the security is traded. If there is no trading volume for a particular valuation day, the last bid price is used. For equity securities traded in the over-the-counter market, the security is valued at the last sale price, or if no sale, at the latest bid price available.

Short-term debt securities with a maturity of 60 days or less are valued at amortized cost, which approximates fair value for such securities.

Debt securities, including short-term debt securities maturing in excess of 60 days, are valued on the basis of prices obtained from an independent pricing source. The pricing source may utilize various pricing methodologies that incorporate both models (which consider factors such as yield, quality, coupon rate, maturity, issue type, quoted prices for similar securities, prepayment speeds and trading characteristics) and dealer-supplied valuations to derive a valuation.

In the rare instance when a price is not available from an independent pricing source or when prices may not reflect fair value, such as when the price provided by the pricing source is not based on a recent trade, a calculated fair value is used, as determined in good faith by the Adviser and reviewed by a Valuation Committee, in accordance with procedures adopted by the Board of Directors of the Investment Company. The Advisor uses a market approach to calculate fair value for equity securities which are categorized as Level 3 above. The Adviser's valuation is primarily based on information regarding the specific equity issuer, such as financial statements, the relationship of per-share book value to the last trade price and operating information. The Adviser also considers industry-specific conditions and overall market conditions, to determine whether the last trade price reflects fair value or needs to be adjusted.

The Retirement Funds and the Allocation Funds value their investments in the underlying Funds of the Investment Company at their respective net asset values.

1.  SIGNIFICANT ACCOUNTING POLICIES AND ORGANIZATION (CONTINUED)

Investment Transactions — Investment transactions are accounted for as of the trade date. 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 are based on the identified cost basis of the security, determined on the first-in, first-out ("FIFO") basis.

Futures Contracts — The Equity Index Fund, Mid-Cap Equity Index Fund and a portion of the All America Fund each maintain indexed asset portfolios which are subject to equity price risk. In order to remain more fully invested in the equity markets while minimizing transaction costs, the funds purchase stock index futures contracts. An initial cash margin deposit (represented by cash or Treasury bills) is made upon entering into a futures contract and serves as collateral for the contract. This initial margin, maintained in a segregated account, is equal to approximately 5%-6% of the contract amount, and 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 by "marking-to-market" on a daily basis to reflect the m arket value of the contract at the end of each trading day. The accumulated unrealized gain or loss on the contract is included in Net Unrealized Appreciation (Depreciation) of Investments in the Components of Net Assets section of the Statement of Assets and Liabilities. Futures contracts are valued at the settlement price established each day by the exchange on which traded. Depending upon whether unrealized gains or losses are incurred, variation margin payments are received or made daily. The net change in unrealized appreciation or deprecation of futures contracts is recorded in the Statement of Operations. When the contract is closed, a realized gain or loss from futures transactions is recorded in the Statement of Operations, equal to the net variation margin received or paid over the period the contract was outstanding.

The "Underlying Face Amount at Value" (appearing in the "Notes to the Summary Portfolio of Investments in Securities") representing the aggregate of outstanding contractual amounts under futures contracts reflects the extent of a Fund's exposure to off-balance sheet risk. The use of futures transactions involves the risk of imperfect correlation in the price movements of the contract and the underlying securities. With futures contracts, there is minimal counterparty credit risk to the Fund since futures are exchange traded and the exchange's clearinghouse, as counterparty to all exchange traded futures, guarantees the futures against default.

During the year ended December 31, 2009, the Equity Index Fund, Mid-Cap Equity Index Fund and the All America Fund purchased futures contracts with total principal amounts of $236,684,125, $151,861,862 and $31,834,353, respectively.

Retirement Funds — Each of the Retirement Funds invests in equity (stock) funds and fixed income (bond) funds and targets different percentages to these asset classes. The targets reflect varying emphases on achieving capital appreciation and gains versus preserving capital and producing income, depending on the specific Fund's time horizon.

The Retirement Funds target their investments in the following underlying funds of the Investment Company in accordance with the percentage allocations noted:

	Equity Index Fund			Mid-Cap Equity Index Fund			Small Cap Growth Fund			Small Cap Value Fund			International Fund			Bond Fund			Mid-Term Bond Fund			Money Market Fund
Retirement Income Fund		20	%		5	%		—			—			—			30	%		30	%		15	%

Generally, rebalancing of the Retirement Funds' holdings is performed on a quarterly or other periodic basis and the mix of underlying Funds is reviewed annually.

Allocation Funds — The Allocation Funds target their investments in the following underlying Funds of the Investment Company in accordance with the percentage allocations noted:

Conservative Allocation:	Equity Index (25%), Bond (30%),
	Mid-Term Bond (45%).
Moderate Allocation:	Equity Index (35%), Bond (30%),
	Mid-Term Bond (20%), Mid-Cap Equity Index (15%).
Aggressive Allocation:	Equity Index (45%), Bond (25%),
	Mid-Cap Equity Index (20%), Small Cap Value (5%), Small Cap Growth (5%).

Generally, rebalancing of the Allocation Funds' holdings is performed on a monthly basis.

Investment Income — Interest income, accretion of discount and amortization of premium are recorded daily on an accrual basis using the effective interest method. A debt obligation may cease accrual of income and result in a reduction to interest income when the collection of all or a portion of current and past due interest is in doubt. 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.

Distributions to Shareholders ("Dividends") — Distributions to shareholders are recorded on the ex-dividend date. It is the Investment Company's policy to make distributions of its net investment income twice a year and, on an annual basis, to distribute net realized gains, if any, in accordance with Federal income tax regulations, which may differ from U.S. generally accepted accounting principles. Accordingly, periodic reclassifications (which do not impact the funds' net asset values) are made within the funds' capital accounts to reflect income and gains available for distribution under Federal income tax regulations.

Federal Income Taxes — Each Fund in 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 or excise tax provision is required.

GAAP requires the evaluation of tax positions taken in the course of preparing a fund's tax return to determine whether it is "more-likely-than-not" that tax positions taken in the fund's tax return will be ultimately sustained, and, if not, a tax liability and expense is recorded.

As of December 31, 2009, management has evaluated the tax positions taken on the Funds' tax returns for all open tax years and has concluded that no tax provision is required in any of the Funds' financial statements. Each Fund's federal and state income, franchise and federal excise tax returns for tax years for which the applicable statutes of limitations have not expired are subject to examination by the Internal Revenue Service and state departments of revenue.

At December 31, 2009, the Funds had the following capital loss carryforwards to offset net capital gains, to the extent provided by Federal income tax regulations, which if unused expire on the dates noted. The Composite, Retirement Income and Mid-Term Bond Funds utilized the following respective amounts of its capital loss carryforward to offset net taxable gains realized in the year ended December 31, 2009: $9,970,637, $5,164 and $720,615. In addition, the Equity Index, All America, Small Cap Value, Composite, and Aggressive Allocation Funds generated post-October 2009 net capital losses of $112,643, $384,318, $1,179,500, $185,041, and $192,001 respectively, which if unused will expire on December 31, 2018.

2.  EXPENSES

The Investment Company has 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 .05% of the value of the net assets of the Retirement Funds, .075% of the value of the net assets of the Equity Index Fund, the Mid-Cap Equity Index Fund and the International Fund, .15% of the value of the net assets of the Money Market Fund, .40% of the value of the net assets of the All America Fund, Composite Fund, Mid-Term Bond Fund and Bond Fund, .55% of the value of the net assets of the Mid Cap Value Fund and .75% of the value of the net assets of the Small Cap Value Fund and Small Cap Growth Fund. The Adviser does not assess a fee for investment management to the Allocatio n Funds. However, shareholders in the Allocation Funds (and the Retirement Funds) will indirectly bear their pro-rata share of the investment management fees incurred by the underlying Funds in which they invest.

Prior to May 1, 2006, the Adviser's investment management fee was .125% of the value of the net assets of the Equity Index Fund and the Mid-Cap Equity Index Fund, .25% of the value of the net assets of the Money Market Fund, .50% of the value of the net assets of the All America Fund, Composite Fund, Mid-Term Bond Fund and Bond Fund, .65% of the value of the net assets of the Mid Cap Value Fund and .85% of the value of the net assets of the Small Cap Value Fund and Small Cap Growth Fund.

Through April 30, 2006, the Adviser contractually limited the expenses of each Fund, other than for brokers' commissions and other fees relating to portfolio transactions, to the amount of the advisory fee paid by the Funds to the Adviser. Effective May 1, 2006, the Adviser terminated its expense limitation policy and each Fund is charged with the full amount of its expenses. Investment company-wide expenses are allocated to each Fund based on its proportional share of net assets or equally, as appropriate.

Under a Sub-Advisory Agreement for the All America Fund, through July 27, 2005 the Adviser delegated investment advisory responsibilities to a subadviser responsible for providing management services for a portion of the Funds' assets. The Adviser (not the Fund) was responsible for compensation payable under such Sub-Advisory Agreement.

The difference between the components of distributable earnings on a tax basis and the amounts reflected in the statements of assets and liabilities are primarily due to wash sales, post-October losses and the Federal income tax treatment of futures contracts.

Reclassifications — Periodically, the Funds may reclassify book to tax differences as a result of the differences arising from the accounting for REIT securities, non-deductible net operating loss, return of capital distributions and Fund distributions for Federal income tax purposes versus financial reporting purposes. Each Fund's net assets are not affected by these reclassifications.

During the year ended December 31, 2009, each Fund reclassified the following book to tax differences [increases (decreases)]:

These financial statements and financial highlights are the responsibility of the Funds' 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 the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. Our procedures included confirmation of securities owned as of December 31, 2009, by correspondence with the custodian and brokers. 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 each of the aforementioned Funds of Mutual of America Investment Corporation as of December 31, 2009, the results of their operations for the year then ended, the changes in their net assets for each of the years in the two-year period then ended, and the financial highlights for each of the years or period in the five-year period then ended, in conformity with U.S. generally accepted accounting principles.
