Semi-Annual Report of Fidelity Investments Variable Insurance Products Funds: Equity-Income Portfolio Semi-Annual Report of Fidelity Investments Variable Insurance Products Funds: Contrafund Portfolio Semi-Annual Report of Fidelity Investments Variable Insurance Products Funds: Asset Manager Portfolio MUTUAL OF AMERICA INVESTMENT CORPORATION The first six months of this year was a challenging period for the financial markets and for investors. The S&P 500 increased by only 3.4% after a 15.2% increase during the last six months of 2003, and a 28.7% increase for all of 2003. This relatively weak stock performance took place as corporations delivered well above expected first quarter earnings and second quarter earnings estimates were raised dramatically. The bond market, as represented by the Lehman Brothers Aggregate Bond Index, increased by a very modest 0.2%, which is remarkable considering that it occurred during a period in which signs of an economic recovery were evident and a Federal Reserve rate increase was imminent. During the first quarter, fears that the recovery would falter on a failure of job growth led to rapid sector rotation in equities and a fair degree of volatility in interest rates. However, a strong jobs report for March, released during the first week of April, confirmed the sustainability of a recovery, but raised a new, and opposite, fear that inflation would accelerate and force the Federal Reserve to raise short term interest rates more quickly and higher than the markets had expected. The rising price of oil also exacerbated inflationary concerns. As a result, long term interest rates increased by over 100 basis points in April and equity markets continued to move sideways. The last two months of the second quarter were marked by the stock market's concern regarding whether the Federal Reserve interest rate hike would be 25 or 50 basis points, how quickly rates would be raised, and by how much rates would eventually rise through the tightening cycle. In addition, investors continued to be concerned by the uncertainty regarding whether a smooth and effective transfer of power would take place in Iraq. While the stock market in aggregate was essentially flat for the period, there was considerable sector rotation in the face of a variety of uncertainties, discussed above. By the end of the second quarter, there was over a 20% difference between the top performing Energy sector and the worst performing Technology sector of the S&P 500. The Energy Sector outperformance was driven by the rise in the price per barrel of oil from $33.77 to an intra-period peak of $42.32. This resulted from high and rising demand, very high capacity utilization and fear of supply disruptions, whether from the Middle East or Russia. The underperformance in Technology resulted from the expectation that the highly leveraged growth in earnings delivered during the first six months of this year would slow considerably in the second half of 2004. Most other sectors showed less diverse price movements; however more defensive sectors (Telecom, Utilities, and Consumer Staples) clearly outperformed more cyclical sectors (Materials, Consumer Discretionary). Similarly, the bond market's total return over the first six months belied a fair degree of interest rate volatility. For instance, 10-year Treasuries closed 2003 at 4.25%, up from 3.82% at the beginning of 2003. During the first quarter of 2004, long rates dropped back to 3.68% as the recovery's endurance came under suspicion with the failure of job growth. However, in response to a strong jobs report for March, and the consequent questions regarding how aggressive the Federal Reserve would be in raising short-term interest rates, 10-year Treasury rates backed up to a high of 4.87% in early June, and closed at 4.58% on the last day of the period. Looking ahead, the consensus view is that the economic recovery will continue, but at a reduced rate of advance; corporate earnings will also grow, but at a slower pace; and the Fed will raise short-term interest rates in modest, probably 25 basis point increments, at each of its next two to three meetings. The key issues of debate and uncertainty remain inflation, especially the price of oil; the continuing threat of terrorism; the Iraqi situation; and, over the next several months, the outcome of the Presidential and Congressional elections in the United States. 1 The total return performance for each of the Mutual of America Investment Corporation Funds is reflected below: Total Returns--Six Months Ended June 30, 2004 Money Market Fund ........................................... +0.4% All America Fund ............................................ +1.2% Equity Index Fund ........................................... +3.3% Mid-Cap Index Fund .......................................... +6.0% Bond Fund ................................................... +0.5% Short-Term Bond Fund ........................................ +0.5% Mid-Term Bond Fund .......................................... -0.5% Composite Fund .............................................. +0.9% Aggressive Equity Fund ...................................... -5.0% Conservative Allocation Fund ................................ +0.6% Moderate Allocation Fund .................................... +2.3% Aggressive Allocation Fund .................................. +2.4% The above total return performance figures do not reflect the deduction of respective Separate Account fees and expenses imposed by Mutual of America Life Insurance Company.

Sincerely, /s/ Manfred Altstadt ---------------------------------------- Manfred Altstadt Chairman of the Board, President and Chief Executive Officer Mutual of America Investment Corporation 2 MONEY MARKET FUND The Money Market Fund's investment objective is to realize high 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 Fund returned 0.79% for the twelve months ended June 30, 2004. Short-term rates remained low during the twelve months ended June 30, 2004 as the Federal Reserve Board kept the Federal Funds rate at 1.00% in an attempt to stimulate the economy. It was not until June 30, 2004 that the Fed Funds rates increased modestly to keep the economy from expanding too quickly. The seven-day effective yield as of August 17, 2004 is 1.2%. 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. ALL AMERICA FUND The investment objective of the All America Fund is to outperform the S&P 500 Index(R). The Fund is approximately 60% invested in the 500 stocks that comprise the S&P 500 Index(R) with the remaining 40% actively managed using four different investment approaches. The actively managed portion of the fund is approximately equally distributed among large-cap growth, small-cap growth, large-cap value and small-cap value. Mutual of America Capital Management Corporation manages the value assets and the small cap growth assets. A sub-advisor manages the large cap growth assets. The U.S. equity markets continued their advances that had started in early 2003 into the first half of 2004, with positive performance across all market caps. However, the overall equity performance in the first half of 2004 was not nearly as robust as that of 2003. Equity markets have been held in check year to date due to opposing forces of strong earnings growth and fairly reasonable equity valuation levels on one side and the prospect of higher interest rates and the inevitable slowing of growth on the other side. The Fund's return for the twelve months ending June 30, 2004 was 20.3% versus the benchmark return of 19.1%.

The S&P 500 Index(R) consists of 500 stocks chosen for market size, liquidity and industry group representation. It is a market-weighted index of 500 stocks that are 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 Index's performance directly proportional to that company's market value. For the twelve months ended June 30, 2004, the S&P 500 Index(R) posted a positive return following three straight years of negative or flat performance. All sectors within the Index posted positive returns with materials and energy representing the best performing sectors. The weakest sectors were telecom services and health care. Within the Index, value stocks outperformed growth stocks during this period. The Fund's performance for the twelve months ended June 30, 2004 was 18.9%, in line with the benchmark return of 19.1%. Note that the Fund's performance includes expenses, such as transaction costs and management fees, which are not carried by the benchmark.

The index 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 index's performance directly proportional to that company's market value. The companies included in the index tend to be typical of this asset class, the medium-capitalized sector of the U.S. securities market. For twelve months ended June 30, 2004, mid-cap stocks outperformed the large-cap S&P 500 Index(R), but trailed the small-cap Russell 2000 Index(R). During this period the S&P 400 Mid-Cap Index(R) generated a positive return after two-years of negative returns. For the 12 months ended June 30, 2004, the best performing sectors were consumer staples and industrials. The weakest sectors were utilities and telecom, although both posted positive returns for the period. Within the index for the period, value stocks outperformed growth stocks. The Mid-Cap Equity Index Fund's performance for the twelve-month period ending June 30, 2004 was 27.6% versus the 28.0% return of the S&P MidCap 400 Index(R). Mid-cap futures do not trade as precisely as the larger cap instruments so the cash flows in and out of the Fund can have a large impact on the performance, which therefore, may vary from the benchmark. In addition, the performance of the Fund includes expenses, such as transaction costs and management fees, which are not carried by the benchmark.

A secondary objective is preservation of capital. The Fund primarily invests in corporate, U.S. Government agency and mortgage-backed securities, all of which normally yield more than U.S. Treaury issues. The ten-year Treasury rate at June 30, 2004 was 4.6%, 1.1% higher than a year ago and over 0.3% higher than year end 2003. Yields on five-year Treasuries also increased by 1.4% from the prior June 30, and over 0.5% over year-end 2003. An increasingly weak dollar and the growing Federal budget deficit combined to push rates higher. Despite rising long-term rates, short-term rates remained relatively low as the Federal Reserve kept the Fed Funds rate at 1.0%, increasing it to 1.25% on June 30, 2004. Mortgage-backed securities outperformed Treasury and Agency issues as volatility decreased and spreads tightened due to increased institutional demand. Corporate bonds, which also outperformed Treasuries and Agencies, benefited from a decline in the default rate, contributing to the positive performance. The Fund's return was 0.9% for the twelve months ending June 30, 2004, compared to the Lehman Brothers Aggregate Bond Index(R) which returned 0.3% for the same period. The primary reason for the outperformance was the overweighting in corporate bonds relative to the index.

The 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 Fund's strategy focuses on well-structured U.S. Government agency mortgage securities, which are normally less volatile than other mortgage-backed securities of similar average lives. Over the 12-month period ended June 30, 2004, the yield on two-year Treasury issues increased from approximately 1.30% to approximately 2.70%. Mortgage securities, which make up a large portion of the Fund but are not in the index, outperformed other securities with similar duration. However, as these bonds mature, generally they will be replaced by corporate bonds. The Fund's return was 1.7% for the twelve months ended June 30, 2004, compared to the Salomon Brothers 1-3 Year Bond Index(R) which returned 0.8% for the same period.

The Fund primarily invests in corporate and U.S. Government agency securities, which normally yield more than U.S. Treasury issues. The Fund is significantly overweighted in Agencies and underweighted in Treasuries, which contributed to outperformance in 2003 but more recently has resulted in underperformance. For the twelve-months ended June 30, 2004, the Fund returned -1.1% compared to the Salomon Brothers 3-7 Year Bond Index(R), which returned -0.2%.

The equity portion of the Fund invests in stocks within the S&P 500 Index(R). The S&P 500 Index(R) continued its advance that started at the beginning of 2003 and lasted into the first half of 2004. However, the index's performance in the first half of 2004 was not nearly as robust as that of 2003. This was mainly due to opposing forces of strong earnings growth and fairly reasonable equity valuation levels on one side, and the prospect of higher interest rates and the inevitable slowing of growth on the other side. The ten-year Treasury rate was 4.6% at June 30, 2004, 1.1% higher than a year ago and over 0.3% higher than year-end 2003. Yields on five-year Treasuries also increased by 1.4% from the prior June 30, and over 0.5% over year-end 2003. An increasingly weak dollar, the growing Federal budget deficit and rallying equity markets all combined to push rates higher. Despite rising long-term rates, short-term rates remained relatively low as the Federal Reserve kept the Fed Funds rate at 1.0%, increasing it to 1.25% on June 30, 2004. Mortgage-backed securities outperformed Treasury and Agency issues as volatility decreased and spreads tightened due to increased institutional demand.

For the twelve months ended June 30, 2004, the small-cap Russell 2000(R) Index returned 33.4%, outperforming larger caps as measured by either the S&P 400 Index(R) or the S&P 500(R). For the period ending June 30, 2004, the best performing sectors were energy and producer durables and the worst performers were utility and financial services. All sectors contributed positively for the period and, overall, value outperformed growth. Over the twelve-month period ended June 30, 2004, the Fund returned 19.7% versus the 33.4% return for the Russell 2000 Index(R). The underperformance for the period was mainly due to the technology, health care and consumer discretionary sectors in the index performing better than the Fund's representation in those sectors.

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 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. There are currently twelve Funds: Money Market Fund, All America Fund, Equity Index Fund, Mid-Cap Equity Index Fund, Bond Fund, Short-Term Bond Fund, Mid-Term Bond Fund, Composite Fund, Aggressive Equity Fund; a Conservative Allocation Fund, Moderate Allocation Fund and Aggressive Allocation Fund (collectively "Allocation Funds", each of which began operations on May 20, 2003). Investment Company shares are issued to Mutual of America Life, and on a limited basis, to 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 accounting principles generally accepted in the United States of America may require 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 is in conformity with accounting principles generally accepted in the United States: Security Valuation -- Investment securities are valued as follows: 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 any 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. The Allocation Funds value their investments in the underlying funds of the Investment Company at their respective net asset values. Debt securities are valued on the basis of prices obtained from an independent pricing service. The pricing service may utilize various pricing methodologies that incorporates both dealer supplied valuations and analytical modeling techniques which considers factors such as yield, quality, coupon rate, maturity, issue type, broker quotes and trading characteristics to derive a valuation. In the rare instance when such a price is not available from an independent pricing service, a fair value is used, as determined in good faith by the Adviser, in accordance with procedures adopted by the Board of Directors of the Investment Company. Short-term debt 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. 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 is based on the identified cost basis of the security, determined on the first-in, first-out ("FIFO") basis. Equity-type funds with an indexed portfolio component may, in order to remain more fully invested in the equity markets while minimizing transaction costs, purchase stock index futures contracts. Initial cash margin deposits (represented by cash or Treasury bills) are made upon entering into futures contracts. (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 market value of the contract at the end of each trading day. 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. 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 the contract was outstanding. The "Underlying Face Amount at Value" (appearing in the "Portfolio of Investments in Securities") representing the aggregate of outstanding contractual amounts under futures contracts reflects the extent of a 66 MUTUAL OFAMERICA INVESTMENT CORPORATION NOTES TO FINANCIAL STATEMENTS (Unaudited) (Continued) 1. SIGNIFICANT ACCOUNTING POLICIES AND ORGANIZATION (CONTINUED) 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. Each of the Allocation Funds invests in equity (stock) funds and fixed income (bond) funds and targets different percentages to these asset classes. The targets reflect three different approaches to asset allocation based on risk tolerance. The Allocation Funds with these percentage allocations invest in the following underlying funds of the Investment Company: Conservative Allocation: Equity Index (25%), Bond (30%), Mid-Term (30%), Short-Term (15%). Moderate Allocation: Equity Index (35%), Bond (30%), Mid-Term (20%), Mid-Cap (15%). Aggressive Allocation: Equity Index (45%), Bond (25%), Mid-Cap (20%), Aggressive Equity (10%). Generally, rebalancing of the Allocation Funds' holdings are performed on a monthly basis. Investment Income -- Interest income, accretion of discount and amortization of premium are recorded on an accrual basis daily. 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 and to distribute net realized gains, if any, on an annual basis, in accordance with federal income tax regulations, which may differ from accounting principles generally accepted in the United States of America. 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.

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 .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, 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 the Mid-Cap Equity Index Fund, and .85% of the value of the net assets of the Aggressive Equity Fund. The Advisor does not assess a fee for investment management to the Allocation Funds. However, shareholders in the Allocation Funds will indirectly bear their pro-rata share of the investment management fees incurred by the underlying funds in which they invest. Under a Sub-Advisory Agreement for the All America Fund, the Adviser has delegated investment advisory responsibilities to a subadviser responsible for providing management services for a portion of the Fund's assets. The Adviser (not the Fund) is responsible for compensation payable under such Sub-Advisory Agreement. The Adviser contractually limits 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 of the Investment Company to the Adviser. This expense limitation remains in effect through 2004 and continues into the successive calendar year unless the Adviser gives adequate notice to terminate or modify its expense limitation policy. 3.
