Annual Report of Fidelity Investments Variable Insurance Products Funds: Equity-Income Portfolio Annual Report of Fidelity Investments Variable Insurance Products Funds: Contrafund Portfolio Annual Report of Fidelity Investments Variable Insurance Products Funds: Asset Manager Portfolio Mutual of America Investment Corporation The year 2004 was characterized by greater-than-normal uncertainty. There was concern early in the year that the nascent economic recovery was not sustainable because job growth remained muted. Also troubling at this time were continually escalating crude oil prices, from the high $20s to $40 per barrel by early summer. Despite these apparent obstacles to growth, the Federal Reserve had been strongly suggesting for some time that short-term interest rates would have to be revised from abnormally low levels. Meanwhile, military efforts to stabilize Iraq so that it could assume self-government were not going as well as had been hoped for. During the first half of 2004, both the bond and stock markets moved sideways, but with a fair degree of volatility. The 10-Year Treasury bond began the year at a yield of 4.25%, fell to 3.68% by the middle of March, and then rose dramatically to a high for the year of 4.87% in mid-June. The stock market reacted to the noted uncertainty by engaging in very rapid sector rotation -- by the end of June, the S&P 500 had advanced little more than 2%, none of the 10 S&P 500 sectors traded outside a range of plus or minus 4% of the overall index, and no one sector ranked either first or last in more than one month. Two important events occurred around June 30th. First, following through on announced plans, the United States Military Command in Iraq handed over political authority to an interim Iraqi government in anticipation of free democratic elections scheduled for January 2005. Second, the Federal Reserve changed the Fed Funds rate for the first time in 13 months with an increase of 25 basis points in what was clearly telegraphed as only the beginning of a monetary tightening cycle. While both of these events eliminated some of the uncertainty that had prevailed, they simultaneously raised new issues. Would the new Iraqi authority succeed in preparing the way to elections, and could the Iraqis assume the responsibility for their own security? As for domestic monetary policy, when and by how much would the Federal Reserve raise rates again, and more importantly, how high would short rates eventually go? Furthermore, the price of oil reached $50 per barrel by the end of September. And during the same period of time, domestic attention shifted to the upcoming Presidential and Congressional elections as the summer political party conventions and subsequent debates focused the issues, making it apparent that the campaign would be intense and the results likely to be very close. In this context, the stock market continued its sideways motion, although energy stocks began to clearly outperform as rising oil prices ensured increasing earnings estimates for companies in this sector. Interestingly, from the end of June, the long-term bond yield proceeded to drift lower, dropping below the 4% level in late October, even while short rates had risen twice in the interim, bringing the Fed Funds rate to 1.75% from the low of 1.00%. Then two pivotal events seemed to give the markets at least a partial respite from the outstanding uncertainties. On October 25th, oil prices peaked at $55 per barrel, and began a quick 5% decline over the next week to close at $49.62 on November 2nd, the day that George W. Bush was reelected to his second term as President of the United States. During the last two months of 2004, the stock market rallied 7%, with the S&P 500 finishing the year exactly 100 points above its prior year close. This year-over-year increase from 1,111.92 to 1,211.92 represented a 9% price advance for the year. When dividends are included, the total return measured 10.9%. The 10-Year Treasury yield drifted up modestly during the same time period despite two Fed Funds rate hikes to end the year at 4.22%, ironically almost exactly the same yield at which it ended 2003 (4.25%). In retrospect, the key driving force behind the stock market in 2004 was the persistence of economic growth and the profits, cash flows and returns that were generated. S&P 500 corporate profits for the fourth quarter of 2004 are likely to be up nearly 20%, which would be the third quarter out of four in which profits advanced 20% or more, confirmation of a powerful recovery. The fact that stock prices did not advance as much as did profits in 2004 has in part to do with the prior year's 28% increase in the S&P 500 in anticipation of the strong profits of 2004, but also as a result of a valuation overhang created by the end of the technology bubble. Price/Earnings multiples expanded dramatically during the final phase of the late 1990s bull market, but have contracted significantly since then. They are still viewed as potentially too high by investors still recovering from a 75% collapse in the Nasdaq Composite and a nearly 50% decline in S&P 500 stocks since 2000. 1 The total return performance for each of the Mutual of America Investment Corporation Funds is reflected below: Total Returns -- Twelve Months Ended December 31, 2004 Money Market Fund .......................................... + 1.10% All America Fund ........................................... + 8.23% Equity Index Fund .......................................... +10.69% Mid-Cap Index Fund ......................................... +16.28% Bond Fund .................................................. + 4.61% Short-Term Bond Fund ....................................... + 1.56% Mid-Term Bond Fund ......................................... + 2.26% Composite Fund ............................................. + 6.34% Aggressive Equity Fund ..................................... + 5.42% Conservative Allocation Fund ............................... + 4.72% Moderate Allocation Fund ................................... + 8.27% Aggressive Allocation Fund ................................. + 9.92% 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 1.10% for the twelve months ended December 31, 2004. Short-term rates moved higher over the second half of 2004 as the Federal Open Market Committee raised the Fed Funds rate five times, bringing it to 2.25%, up from 1.0% on December 31, 2003. The seven-day effective yield as of February 15, 2005 is 2.31%. 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 started in early 2003 through year-end 2004, with positive performance across all market caps. However, the overall equity performance in 2004 was not nearly as robust as that of 2003. Equity markets have been held in check 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 December 31, 2004 was 8.23% versus the benchmark return of 10.88%, due to underperformance of the active small-cap growth and large-cap growth portions of the Fund.

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 December 31, 2004, the S&P 500 Index(R) had a positive double digit return for the second consecutive year following three years of negative performance. All sectors within the Index posted positive returns with energy and utilities representing the best performing sectors. The weakest sectors were healthcare and technology. The Fund's performance for the twelve months ended December 31, 2004 was 10.69%, in line with the benchmark return of 10.88%. Note that the Fund's performance includes expenses, such as transaction costs and management fees, which are not reflected in 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 the twelve months ended December 31, 2004, the S&P 400 outperformed the S&P 500 Index(R) for the fifth consecutive year. During this period the S&P 400 Mid-Cap Index(R) generated its second consecutive year of double-digit growth after two years of negative returns. For the 12 months ended December 31, 2004, the best performing sectors were energy and materials. The weakest sector was technology; the only sector to post a negative return. The Mid-Cap Equity Index Fund's performance for the twelve-month period ending December 31, 2004 was 16.28% versus the 16.48% 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 larger 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 reflected in 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. Treasury issues. The Fund measures its performance against the Lehman Brothers Aggregate Bond Index(R) ("Index"). The ten-year Treasury rate on December 31, 2004 was 4.22%, three basis points lower than the prior year-end. Conversely, yields on five-year Treasuries increased by 36 basis points, finishing 2004 at 3.61%. After five rate hikes over 2004 the Fed Funds rate finished the year at 2.25%, causing short rates to move higher. Concerns over both inflation, though still tame, and economic growth drove longer rates lower causing the yield curve to flatten considerably. The spread between the two-year treasury yield and the 30-year treasury yield declined by 149 basis points, finishing 2004 at 176 basis points. In the Index, corporate bonds outperformed Treasuries and Agencies due to improved fundamentals and a 50% decline in the default rate. Mortgage-backed securities, which also outperformed Treasuries and Agencies, benefited as a result of low volatility and increased demand from foreign central banks. The Bond Fund's return for 2004 was 4.61%, compared to 4.34% for the Index. The primary reason for the outperformance was the overweighting in corporate bonds relative to the Index. The effects of the outperformance are further enhanced when one considers that the performance of the Fund includes expenses, such as transaction costs and management fees, which are not reflected in the benchmark.

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 overweighting corporate and agency bonds, which yield more than competing index sectors. Over the 12-month period ended December 31, 2004 the yield on two-year Treasury issues increased from 1.82% to 3.07%. Mortgage-backed securities, which make up a large portion of the Fund, outperformed other securities with a similar duration. However, as these bonds mature, generally they will be replaced by corporate bonds. The Fund's return was 1.56% for 2004, compared to the Citigroup 1-3 Year Government and Corporate Index(R) return of 1.29% for the same period, due to strong performance in mortgage-backed securities and a concentration in agency bonds. The effects of the outperformance are further enhanced when one considers that the performance of the Fund includes expenses, such as transaction costs and management fees, which are not reflected in the benchmark.

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 and corporate bonds compared to the Citigroup 3-7 Year Government and Corporate Index(R) ("Index"). For the twelve months ended December 31, 2004, the Fund returned 2.26% compared to the Index, which returned 3.42%, due to the underweighting in corporate bonds.

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 through the end of 2004. However, the index's performance in 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 on December 31, 2004 was 4.22%, three basis points lower than one year ago. Conversely, yields on five-year Treasuries increased by 36 basis points, finishing 2004 at 3.61%. After five rate hikes over 2004, Fed Funds finished the year at 2.25%, causing short rates to move higher. Concern over both inflation, though still tame, and economic growth drove longer rates lower, causing the yield curve to flatten considerably. The spread between the two-year treasury yield and the 30-year treasury yield declined by 149 basis points, finishing 2004 at 176 basis points. In the Lehman Brothers Aggregate Bond Index(R), corporate bonds outperformed Treasuries and Agencies due to improved fundamentals and a 50% decline in the default rate. Mortgage-backed securities, which also outperformed Treasuries and Agencies, benefited as a result of low volatility and increased demand from foreign central banks. For the twelve months ended December 31, 2004, the Composite Fund returned 6.34% compared to the benchmark return of 7.30%, 40% of which is based on the Lehman Brothers Aggregate Bond Index(R) (which returned 4.34%), 50% of which is based on the S&P 500 Index(R) (which returned 10.88%) and 10% of which is based on the Citigroup 3-Month T-Bill Index(R) (which returned 1.24%). The underperformance was attributable to the equity portion of the Fund, specifically an underweighting in the energy sector and an emphasis on particular segments of the healthcare industry.

For the twelve months ended December 31, 2004, the small-cap Russell 2000(R) Index returned 18.33%, outperforming larger caps as measured by either the S&P 400 Index(R) or the S&P 500 Index(R). For the period ending December 31, 2004, the best performing sectors were financial services and materials & processing; the worst performer was technology. All sectors, with the exception of technology, contributed positively for the period and, overall, value outperformed growth. Over the twelve-month period ended December 31, 2004, the Fund returned 5.42% versus an 18.33% return for the Russell 2000 Index(R). The underperformance for the period was mainly due to an overconcentration within components of the technology and health care sectors, which under-performed relative to the index.

The Fund's target allocation is approximately 75% of net assets in fixed income Funds and approximately 25% of net assets in equity Funds. The Fund seeks to maintain approximately 30% of its net assets in the Bond Fund, approximately 30% in the Mid-Term Bond Fund, approximately 15% in the Short-Term Bond Fund and approximately 25% in the Equity Index Fund. The objective of the Conservative Allocation Fund is current income and, to a lesser extent, capital appreciation. Performance for the Fund is compared to the Lehman Brothers Aggregate Bond Index(R) (75% weighting) and the S&P 500 Index(R) (25% weighting). For the twelve months ended December 31, 2004, the Fund returned 4.72% versus a 5.98% return based on the weighted returns in the Lehman Brothers Aggregate Bond Index(R) and the S&P 500 Index(R). The Fund's underperformance was due to the portion of its investments in the shorter-term bond funds, which underperformed the longer-term benchmark.

The Fund's target allocation is approximately 50% of net assets in equity Funds and approximately 50% of net assets in fixed income Funds. The Fund seeks to maintain approximately 35% of its net assets in the Equity Index Fund, approximately 15% in the Mid-Cap Equity Index Fund, approximately 30% in the Bond Fund and approximately 20% in the Mid-Term Bond Fund. The objective of the Moderate Allocation Fund is capital appreciation and current income. Performance for the Fund is compared to the S&P 500 Index(R) (50% weighting) and the Lehman Brothers Aggregate Bond Index(R) (50% weighting). For the twelve months ending December 31, 2004, the Fund returned 8.27% versus a 7.61% return based on the weighted returns of the S&P 500 Index(R) and the Lehman Brothers Aggregate Bond Index(R). The Bond Fund portion of the Fund outperformed the Lehman Index (due to the Fund's overweighting in corporate bonds) and the Mid-Cap Equity Index Fund portion of the Fund outperformed the S&P 500 Index(R), which leans more towards large-cap stocks. The effects of the outperformance are further enhanced when one considers that the performance of the Fund includes expenses, such as transaction costs and management fees, which are not reflected in the benchmark.

The Fund's target allocation is approximately 75% of net assets in equity Funds and approximately 25% of net assets in fixed income Funds. The Fund seeks to maintain approximately 45% of its net assets in the Equity Index Fund, approximately 20% in the Mid-Cap Equity Index Fund, approximately 10% in the Aggressive Equity Fund and approximately 25% in the Bond Fund. The objective of the Aggressive Allocation Fund is capital appreciation and, to a lesser extent, current income. Performance for the Fund is compared to the S&P 500 Index(R) (75% weighting) and the Lehman Brothers Aggregate Bond Index(R) (25% weighting). For the twelve months ending December 31, 2004, the Fund returned 9.92% versus a 9.25%% return based on the weighted returns of the S&P 500 Index(R) and the Lehman Brothers Aggregate Bond Index(R). The Fund's outperformance was due to its investments in the Mid-Cap Equity Index Fund and the small-cap stocks included in the Aggressive Equity Fund, which outperformed the S&P 500 Index(R). In addition, the Bond Fund outperformed the Lehman Index due to the Fund's overweighting in corporate bonds. The effects of the outperformance are further enhanced when one considers that the performance of the Fund includes expenses, such as transaction costs and management fees, which are not reflected in the benchmark.

You do not incur transactional costs, such as sales charges (loads), redemption fees or exchange fees. Additionally, Mutual of America Capital Management Corporation, the Funds' Advisor, has contractually agreed to limit each Fund's total operating expenses to its investment management fees. This contractual obligation remains in effect for 2005 and will continue for each following calendar year unless the Advisor gives notice to the Investment Company within two weeks before the next calendar year begins. 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, 2004 and held for the entire period ending December 31, 2004. 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.

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, a Moderate Allocation Fund and an 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 are 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 are 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 "Summary Portfolio of Investments 58 MUTUAL OF AMERICA INVESTMENT CORPORATION NOTES TO FINANCIAL STATEMENTS (Continued) 1. Significant Accounting Policies and Organization (Continued) 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. 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 invest 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 (30%), Short-Term Bond (15%). 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%), 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 daily on an accrual basis. 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. At December 31, 2004, certain funds had the following capital loss carryforwards to offset net capital gains, to the extent provided by Federal income tax regulations. In addition, the Bond Fund generated a post-October 2004 net capital loss of $65,144, which if unused, will expire on December 31, 2013.

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 2005 and continues into the successive calendar years unless the Adviser gives adequate notice to terminate or modify its expense limitation policy. 3.

These financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. The financial highlights for each of the years in the two-year period ended December 31, 2001 were audited by other auditors who have ceased operations. Those auditors expressed an unqualified opinion on those financial highlights in their report dated February 20, 2002. 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, 2004, by correspondence with 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 assets and liabilities of the Funds as of December 31, 2004, the results of their operations for the year then ended, changes in their net assets for each of the years or period in the two-year period then ended, and the financial highlights for each of the years or period in the three-year period then ended, in conformity with U.S. generally accepted accounting principles. /s/ KPMG LLP New York, New York February 28, 2005 65 MUTUAL OF AMERICA INVESTMENT CORPORATION Directors and Officers -- unaudited The tables below show information about the Directors and officers of the Investment Company.
