MUTUAL OF AMERICA INVESTMENT CORPORATION

We are pleased to present the Mutual of America Investment Corporation (the “Investment Company”) Semi-Annual Report. This Report includes important information regarding the performance and financial position of the Investment Company’s funds for the six months ended June 30, 2014.

Most Equity Markets Up

During the first six months of 2014, every asset class registered positive returns. With regard to U.S. stocks, the S&P 500^® Index (S&P 500) increased by 7.14%, the Russell Midcaps by 8.67% and the Russell Small Caps (Russell 2000) by 3.19%. The Dow Jones Industrial Average, S&P 500 Index and Russell Midcap Index closed the period at or very near all-time highs. All 10 sectors of the S&P 500 advanced during this timeframe. In addition, the MSCI World Equity Index posted a year-to-date advance of 4.96%, with individual sectors advancing in a range from 1.71% to 6.08%.

Such good overall equity returns for the period are particularly noteworthy as they followed 2013 double-digit full-year returns for most developed and frontier markets, although emerging markets underperformed significantly.

U.S. Bond Returns Also Broadly Positive

The Barclays Capital Aggregate Index for all U.S. bonds was up 3.93%, with the lowest investment grade bonds (BBB) advancing 7.1%, and all bonds with maturities of greater than 10 years registering positive returns of 10.32%. In addition, all long-term sectors of the U.S. bond market advanced by double-digits during the period: U.S. long-term Treasury securities increased 12.14%, long-term Investment Grade securities were up 11.22% and long-term High Yield bonds advanced 13.06%. The lowest grade long-term High Yield bonds (CC-D) generated returns of 29.4%. Similarly, all global bond markets in aggregate showed positive returns, although not as robust as those for U.S. bonds.

Bond Market at Odds with Equity Market

The behavior of equity markets would suggest a consensus that global growth will accelerate from very sluggish rates during the first half of this year. However, the behavior of bond yields suggests that bond investors are more skeptical. The 10-Year U.S. Treasury Bond yield declined from 3.03% at the beginning of the year to as low as 2.44% in late May, although it rose quickly in early June to about 2.6%. However, through the end of May, long-term Treasury securities generated total returns in excess of 12%, almost three times those of the S&P 500 and Dow Jones indexes. The declines in the bond yields of troubled European sovereign nations over the past two years is more a reflection of the perception that policy actions taken have significantly reduced the risk that the Eurozone will collapse and the euro will disappear.

The key debate among market commentators over the past few months has been the apparent disagreement between equity and bond markets regarding the future prospects for growth. There are a number of plausible explanations for the decline in U.S. Treasury yields beyond fear that growth will disappoint. These include but are not limited to:

— money flows from Europe, because spreads in the Eurozone bond markets have shrunk relative to those in the U.S.;

— long-term reduction in expected inflation;

— continued weakness in the Chinese Yuan and

— a flight to quality in the face of rising geopolitical risk

While it is almost impossible to prove any of these explanations, some are reasonable enough to suggest that fear of a slowdown or recession may not be the primary catalyst for the decline in U.S. rates.

However, though U.S. economic data during the first couple of months of the 2nd quarter of 2014 were stronger than during the adverse-weather-impacted 1st quarter of 2014, they were not as robust as many economists had expected.

U.S. Sector Data Generally Positive

Nevertheless, June’s data flow showed accelerating strength. Should that continue, estimates for growth during the second half of 2014 could actually begin to rise. Almost all manufacturing surveys have indicated continuing strong and accelerating growth. The auto industry has been especially strong, almost reaching an annualized rate of 17 million vehicles produced in May, close to the prerecession run rate. And the employment statistics, which Janet Yellen, the Chair of the Federal Reserve Board, flagged as key to any future changes in monetary policy, have continued to show steady, though modest, improvement. Initial jobless claims are running at close to the 300,000 per month level that has historically been associated with sustainable economic growth. Nonfarm payrolls, perhaps the most-watched

1

employment statistic, have been averaging an addition of close to 200,000 jobs per month over the past six to nine months, and registered a robust increase of 288,000 for June versus a consensus of 217,000, with the previous two months data revised upward.

This pace of job creation, as in the case of jobless claims, has historically signaled sustainable growth, although not necessarily robust growth. In June, the unemployment rate stood at 6.1%, its lowest level since April 2008 and down from a peak of 10% at the end of 2009. In addition, the labor participation rate, which has been falling since October 2008, seems to have stabilized. At the same time, the average work week and average hourly earnings have shown little growth improvement, largely accounting for anemic growth in personal income and in weak spending by consumers.

While not all the data are strong, they indicate the U.S. economy continues to improve with suggestions of acceleration. There is, however, a growing risk that the Federal Reserve will begin to raise policy rates sooner than the currently anticipated second half of 2015 should growth and/or inflation show signs of rising at an increasingly accelerating pace.

Ongoing Risks Remain a Threat to Global Growth

The risks we’ve repeatedly discussed over the past couple of years remain. China’s growth has slowed, and may slow even further, as policy officials grapple with a housing bubble and over-capacity in a number of industries.

Europe also continues to struggle with growth. A strong euro, continued austerity among a number of troubled sovereign nations and weakness in key export markets have all conspired to suppress growth, which has recently turned positive, but just barely. Compounding the growth problem is inflation, which has been decelerating, threatening deflation — an affliction that incapacitated the Japanese economy for more than 20 years.

Japan is in the process of trying to break out of the gravitational pull of deflation, primarily through an aggressive quantitative easing program focused on creating a weaker yen and higher inflation, as well as reform efforts designed to encourage higher wages; more business and consumer spending; and a more flexible, less bureaucratic financial system.

Europe has recently responded to decelerating inflation somewhat less aggressively than Japan, but by historical standards, the steps taken by the European Central Bank (“ECB”) are monumental. While stopping short of outright quantitative easing, the ECB lowered the rate paid to banks on excess reserves to -0.1%, meaning the banks must pay to keep deposits of their excess reserves at the central bank. The expectation is that banks will withdraw their excess reserves and begin making loans to stimulate the economy. In addition, the ECB renewed a program of making short-term (i.e., four years or less) loans to banks on condition that they use these funds to make loans to businesses and consumers. Finally, the ECB will change its practice of “sterilizing,” or neutralizing, the effect of its normal operations of buying bonds in the open market to facilitate seasonal liquidity needs. Normally, the central bank would shortly thereafter sell bonds back into the market in order to withdraw the liquidity its bond purchases had temporarily created. Going forward, the ECB has stated that it will not reverse bond purchases, thus allowing the extra liquidity to remain in the system. This technique is essentially a mini-quantitative easing program. Thus, more money will remain in the system as a further stimulus to economic activity.

At issue is whether or not these actions will have the desired effect. Excess reserves can be withdrawn from the central bank and invested risk-free in U.S. Treasury securities that offer at least marginally positive returns on short maturities, and more if the purchaser is willing to extend the maturity of their purchases one to two years. Some commentators claim that European banks had already begun to do this prior to the ECB’s action. Thus, such invested excess reserves would be unavailable for making loans.

Despite these shortcomings, the fact that the ECB took such uncharacteristically aggressive steps will make further actions such as outright quantitative easing more palatable in the future for what has long been one of the most conservative financial entities in the world.

There are also the inevitable risks that will come with the end of the Fed’s quantitative easing program. If statistics on employment show rapid improvement, or inflation begins to accelerate, investors will pull forward their expectations of rate increases. Markets will react with greater volatility and, at least initially, a negative response. Equities should continue to rise in this recovery as they have in the past, even in the face of rising rates for a prolonged period, as long as the economy and profits continue to grow. Bond prices longer term should fall, pushing up yields as demand for capital increases and forward expectations of inflation increase.

Geopolitical risk has long been a background risk to all economic analyses, whether over the last five, 25, 100 or 1,000 years. These risks ebb and flow in importance to market participants, but rarely impact markets for any sustained period of time unless they lead to clear economic disruptions. The most likely transmission of these geopolitical risks to the global economy would be through rising oil prices. Yet markets to date do not seem to have responded with

2

outsized concerns. Oil prices did rise about 6% immediately following Russia’s annexation of Crimea, but have since totally retraced the increase. Unless any of these or other geopolitical issues begin to directly and observably impact the prospects for global growth, markets should remain focused on economic fundamentals. As discussed, these fundamentals, while weak, have persistently shown modest improvement over the past few years.

Near-Term Outlook for U.S. Domestic Growth and Market Performance

Specifically focusing on the U.S., equity markets tend to be driven by corporate earnings. The statistics for 1st quarter earnings for the S&P 500 support the notion of continued slow growth. Sales and earnings during the same period came in ahead of beginning-of-quarter expectations, at 2.0% and 6.0%, respectively. Of all companies reporting, more than 70% came in above expectations, ahead of the long-term average of about 65%. Importantly, margins held steady at close to historical highs. Despite these seemingly good results, sales remain subpar due to persistently slow economic growth, and earnings have been getting an assist from “financial engineering” in the form of share repurchases, rather than being generated by purely operational factors.

For the bond market, short rates should continue to be anchored by the Fed’s commitment to maintain policy rates near zero for an extended period of time. Any acceleration in economic growth, inflation or inflation expectations would most likely result in an upward movement in longer-term Treasury rates and widening corporate bond spreads. However, many investors have been hurt badly over the past several years trying to anticipate an increase in long rates. These rates surely will rise, at some point in time, and owners of long-term bonds will experience capital losses. The key question is: When will that happen?

The first catalyst probably will be evidence of any strong acceleration in economic growth, which in turn, would prompt the Federal Reserve to start raising policy rates shortly thereafter. Recent strong economic data has encouraged a number of economists to pull forward their projected start dates from the second half of 2015 to earlier in the year. When that time comes, equity markets may experience a correction, but as long as improving economic growth persists, and earnings rise, markets should recover and move to new highs until the cycle ends. Our best guess is that point will not be reached for at least two to three years.

As a result, we expect equity markets to continue to advance steadily but slowly for a longer period of time. One could argue that the slowness of this recovery has raised the prospects that we are only around the halfway point in the expansion, which has just clocked its 63rd month, slightly above the 57-month average for all post-World War II expansions. Note that the 12 million jobs lost in the Great Recession of 2008-2009 are just now on the verge of being fully replaced and few end-of-cycle economic signals have appeared.

Long-Term Concerns

The key long-term concern for investors and policy makers worldwide is what unanticipated consequences will be experienced when the inevitable unwinding of the unprecedented aggressive quantitative easing of the past five years begins in earnest.

The first concern that has been raised over the past few years is the prospect of runaway inflation, much like in the 1970s, this time as a result of the staggering amount of liquidity that has been pumped into the global financial system. Should those funds begin to be utilized aggressively by businesses for investment in fixed capital and labor rather than in financial assets, “too much money chasing too few goods” would likely drive up prices. Whether or not the central banks will have the wisdom to know when, or in what increments, or with what tools to withdraw liquidity without either not doing enough to prevent inflation, or doing too much and prompting a recession, remains an open-ended question.

A second and related concern that has been raised is the fear that the tremendous amount of liquidity in the financial system will generate a “bubble,” or bubbles, which will inevitably burst. We have several recent examples: The Savings and Loan crisis in the late 1980s and early 1990s, the Japanese housing collapse in 1989, the “Tech Wreck” of 2000 and of course the U.S. Real Estate Bust of 2008 that caused the so-called “Great Recession,” from which we have been attempting to exit for some time.

Recent comments by Janet Yellen that it was not the Fed’s job to use monetary policy to manage financial crises only heightened the concern over bubbles, which are generally financial in origin. The remark was even more astonishing given that Federal Reserve actions in response to the 2008 implosion of the financial system was the classic case of monetary policy addressing a financial crisis. In fairness, however, her statement included an expression of belief that regulatory oversight would in the future be sufficient to preclude another financial crisis and that the job of the Fed going forward would be to focus exclusively on its dual mandate to ensure price stability and full employment. History would suggest that regulations are usually put in place after a crisis, are designed to address the causes of that crisis and inevitably fail to anticipate the causes of the next one.

3

In short, it is probable that we will eventually face another economic or financial crisis. It is likely that no one, at least those in positions of authority and power, will foresee it. That is because by the time a bubble is about to burst, politicians and regulators will have become convinced their remedies for the prior meltdown have and will continue to work, and market participants will be blinded by their exuberance over some asset, or set of assets, whose values have soared. Unanticipated consequences can’t be anticipated.

The good news is that such an event is probably well off in the future. The heightened vigilance of the Federal Reserve and other central banks around the world, the extreme reluctance of businesses and consumers to spend and for banks to lend, and the current complacency within the financial markets suggest we are still in the “fear” phase rather than the “greed” phase of the market and economic cycle. Bubbles generally burst when no one is looking anymore. We’re not there yet.

EQUITY INDEX FUND

The Equity Index Fund’s objective is to replicate the performance of the S&P 500^® Index (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 had a strong first half of 2014, returning 7.14% including dividends. The S&P 500 closed the half-year at nearly its all-time high level on June 30, 2014. Utilities, Energy and Healthcare were the best performing sectors of the year to date period, returning 18.7%, 13.0% and 10.6%, respectively. No sectors had a negative return but Consumer Discretionary, Industrials, and Telecom were the worst performing, with returns of 0.6%, 4.0% and 4.3%, respectively.

The Equity Index Fund’s performance for the six months ended June 30, 2014, was 7.12% before expenses and 7.04% after expenses, in line with the benchmark return of 7.14%. 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 (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 six months ended June 30, 2014, the S&P 500 of large capitalization stocks increased by 7.14% on a total return basis, while the Russell 2000^® Growth Index was up 2.22% and the Russell 2000^® Value Index was up 4.20%.

The All America Fund’s return for the six months ended June 30, 2014, before expenses was 6.17% and 5.93% after expenses versus the benchmark return of 7.14%. The underperformance of the Fund was the result of under-performance by the Small Cap Growth, Small Cap Value and Active Large Cap components of the Fund. The Equity Index modestly out-performed the benchmark.

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 six months ended June 30, 2014, the Small Cap Value Fund returned 4.35% before expenses and 3.95% after expenses versus a 4.20% return for the Russell 2000 Value Index. Within the benchmark, the best performing sectors were Utilities and Energy while the worst sectors were Finance and Basic Materials.

Stock selection was the primary driver of negative performance versus the benchmark. Sectors contributing to Fund performance included Industrials and Health Care, while sectors detracting from Fund performance included Energy and Retail.

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 1.52% before expenses and 1.10% after expenses during the six months ended June 30, 2014. The Fund’s benchmark, the Russell 2000^® Growth Index, returned 2.22% for the period.

The first six months of the year were lackluster compared to the returns seen in 2013. The small capitalization growth marketplace showed its volatility compared to other equity classes. The Russell 2000 Growth Index showed a 6.2% return for the month of June bringing the index back into positive territory.

The Consumer Discretionary sector is showing the poorest performance as weather was particularly cold during the first quarter of the year and consumer discretionary income was into services. In addition, given the cold weather, housing activity has been lackluster. The small capitalization sector has more exposure to housing and its related industries than do the mid and large capitalization sectors. Nonetheless, with lower interest rates since the beginning of the year, industries with relatively attractive yields have particularly benefitted such as Real Estate Investment Trusts (REITs).

6

The Energy sector has showed the most attractive performance given the tensions in the Middle East and the Ukraine. We had very competitive returns in this area. Most beneficial to our Fund have been Health Care and Consumer Staples. Detracting from the Fund has been the Consumer Discretionary and Materials sectors.

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 six months ended June 30, 2014, the Mid Cap Value Fund returned 9.42% before expenses and 9.10% after expenses versus an 11.14% return for the Russell Midcap Value Index. Within the benchmark, the best performing sectors were REITs and Utilities while the worst sectors were Retail and Finance.

Adverse stock selection was the primary driver of performance versus the benchmark. Sectors contributing to Mid Cap Value Fund performance included Consumer Staples and Industrials while sectors detracting from Fund performance included Technology and Energy.

MID-CAP EQUITY INDEX FUND

The Mid-Cap Equity Index Fund invests in the 400 stocks that comprise the S&P MidCap 400^® Index (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 outperformed the S&P 500^® for the first half of 2014, at 8.7% versus 7.1% for the large cap stocks. The outperformance is a continuation of strong Mid Cap performance for 2013. Within the S&P MidCap 400, Telecom, Utilities and Energy sectors were up substantially, advancing 18.7%, 18.6%, and 16.5% respectively. The worst performing sector was Consumer Discretionary with a return of 2.2%.

The Mid-Cap Equity Index Fund’s performance for the six months ended June 30, 2014, was 7.53% before expenses and 7.44% after expenses, in line with the 7.50% 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.

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 mainly in exchange traded funds that reflect the MSCI EAFE Index. The Fund also has invested a small percentage of assets in exchange traded funds that provide exposure to emerging markets and to companies with small market capitalizations in developed market countries.

For the six months ended June 30, 2014, the International Fund returned 4.23% before expenses and 4.15% after expenses, underperforming the 4.78% return of the benchmark. During the 2nd quarter the fund added exposure to International Small Cap and Emerging Markets which both outperformed the Index. The fund’s benchmark closes earlier in the day than the actual market for the fund’s investments. This time lag can result in both positive and negative performance differences. The fund’s securities closed at lower levels relative to the benchmark on June 30th, and higher levels relative to the benchmark on December 31, 2013, both of which adversely impacted the performance for the six month period.

COMPOSITE FUND

For the six months ended June 30, 2014, the fixed income portion of the Fund had a total return of 4.71% (before expenses), compared to the Barclays Capital Aggregate Bond Index, which returned 3.93% for the period. The fixed income portion of the Fund focused on income and capital preservation.

The Federal Reserve continued to emphasize low short-term rates in order to stimulate the economy, re-liquefy the banking system and support the mortgage market. As an example, 30-Day Treasury Bill yields ended 2013 at one basis point and remained at that level on June 30, 2014. One year Treasury Bills were also little changed, starting at 16 basis points and ending at 15 basis points in June.

7

Intermediate and longer dated issues declined during the recent six months in response to Federal Reserve intervention in the market. For example, seven year Treasury Notes declined from 2.45% to 2.14%. Similarly, 30 year Treasury Bonds ended 2013 at 3.97% and declined to 3.36%. As a result, the broad bond market indices registered positive returns for the first half of 2014.

Yield spreads between corporate and Treasury Bonds continued to narrow as investors sought securities with higher yields. This emphasis on income and the resulting capital gains enabled the High Grade bond market to outperform the High Yield market by 31 basis points on a total return basis, according to data provided by CreditSights. On average, “BBB” corporate bonds returned 7.09%, a favorable comparison to the “A” rated average of 5.15% and the “BB” average of 5.99%

The strategy of the fixed income portion of the Fund was to maintain a similar maturity profile to the Aggregate Index with an overweighting of BBB issuers. Intermediate maturities were emphasized, as was diversification. This was done to protect the Fund from unexpected credit events, so few holdings exceeded one-half of one percent of the Fund’s value. The extreme diversification proved unnecessary, but will be maintained going forward as part of our risk control.

RETIREMENT INCOME FUND

The objective of the Retirement Income Fund is current income consistent with the preservation of capital and, to a lesser extent, capital appreciation. The Retirement Income Fund invests primarily in the fixed-income funds of the Investment Company and also invests in two equity funds of the Investment Company. The Fund’s current target allocation is approximately 75% of net assets in fixed-income funds (approximately 30% in the Bond, 40% in the Mid-Term Bond Funds and 5% in the Money Market Fund) and approximately 25% of net assets in equity funds (20% in the Equity Index Fund and 5% in the Mid-Cap Equity Index Fund).

Performance for the Retirement Income Fund is compared to the Barclays Capital Aggregate Bond Index (70% weighting), the Citigroup 3-Month Treasury Bill Index (5% weighting) and the S&P 500^® Index (25% weighting). For the six months ended June 30, 2014, the Fund returned 4.50% versus a 4.53% return in the weighted benchmark. The slight underperformance of the Fund is mainly attributable to the underperformance of the Mid-Term Bond Fund and the Money Market Fund relative to the Barclays Capital Aggregate Bond Index.

2010 RETIREMENT FUND

The objective of the 2010 Retirement Fund is current income and capital appreciation appropriate for the asset allocation associated with a target retirement in 2010. The 2010 Retirement Fund invests in funds of the Investment Company. The Fund’s current target allocation is approximately 63% of net assets in fixed-income funds (approximately 25% in the Bond Fund, 33% in the Mid-Term Bond Fund and 5% in the Money Market Fund) and approximately 37% of net assets in equity funds (25% in the Equity Index Fund, 9% in the Mid-Cap Equity Index Fund and 3% in the International Fund) (See Note 1 in the Notes to Financial Statements for additional information on changes to Fund target allocations during 2014).

Performance for the 2010 Retirement Fund is compared to the Barclays Capital Aggregate Bond Index (58% weighting), the Citigroup 3-Month Treasury Bill Index (5% weighting) and the S&P 500^® Index (37% weighting). For the six months ended June 30, 2014, the Fund returned 4.95% versus a 4.92% return in the weighted benchmark. The slight outperformance of the Fund is mainly attributable to a small overweight to equities in the fund relative to the fund’s targeted allocation, partially offset by the underperformance of the Mid-Term Bond Fund and the Money Market Fund relative to the Barclays Capital Aggregate Bond Index.

2015 RETIREMENT FUND

The objective of the 2015 Retirement Fund is current income and capital appreciation appropriate for the asset allocation associated with a target retirement in 2015.

Performance for the 2015 Retirement Fund is compared to the S&P 500^® Index (47% weighting) and the Barclays Capital Aggregate Bond Index (53% weighting). For the six months ended June 30, 2014, the Fund returned 5.20%

versus a 5.43% return in the weighted benchmark. The underperformance of the Fund is mainly attributable to the underperformance of the Mid-Term Bond Fund relative to the Barclays Capital Aggregate Bond Index.

2020 RETIREMENT FUND

The objective of the 2020 Retirement Fund is current income and capital appreciation appropriate for the asset allocation associated with a target retirement in 2020. The 2020 Retirement Fund invests in funds of the Investment Company. The Fund’s current target allocation is approximately 57% of net assets in equity funds (approximately 33% in the Equity Index Fund, 11% in the Mid-Cap Equity Index Fund, 9% in the International Fund and 2% each in the Small Cap Growth and Small Cap Value Funds) and approximately 43% of net assets in fixed-income funds (25% in the Bond Fund and 18% in the Mid-Term Bond Fund) (See Note 1 in the Notes to Financial Statements for additional information on changes to Fund target allocations during 2014).

Performance for the 2020 Retirement Fund is compared to the S&P 500^® Index (57% weighting) and the Barclays Capital Aggregate Bond Index (43% weighting). For the six months ended June 30, 2014, the Fund returned 5.37% versus a 5.76% return in the weighted benchmark. The underperformance of the Fund is mainly attributable to the underperformance of the Mid-Term Bond Fund relative to the Barclays Capital Aggregate Bond Index, and the underperformance of the International Fund and small cap funds relative to the S&P 500 Index

2025 RETIREMENT FUND

The objective of the 2025 Retirement Fund is current income and capital appreciation appropriate for the asset allocation associated with a target retirement in 2025.

Performance for the 2030 Retirement Fund is compared to the S&P 500^® Index (77% weighting) and the Barclays Capital Aggregate Bond Index (23% weighting).

The Aggressive Allocation Fund invests in the equity and fixed-income funds of the Investment Company.

The underperformance of the Fund is mainly attributable to the underperformance of the International Fund and the small cap funds relative to the S&P 500 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 0.04% before expenses and -0.07% after expenses for the six months ended June 30, 2014, compared to a 0.02% return for the Citigroup 3-Month Treasury Bill Index. Note that the benchmark performance does not reflect any expenses.

During the first half of 2014, the Federal Reserve remained committed to a near-zero interest rate policy by keeping the Fed Funds target rate at a range of 0% to 0.25%. As a result, money market returns were affected by extremely low yields and a decrease in supply of eligible investments. The Fund’s strategy continued to focus on quality, liquidity, and maintaining a relatively short weighted average maturity.

The seven-day effective yield as of August 12, 2014, was -0.19%. 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 emphasized corporate issues during the first six months of 2014 in order to capture incremental income. The Fund will continue to focus on income, rather than market volatility, to achieve superior returns over market cycles. In addition, the Fund’s corporate securities will remain highly diversified in order to shield the portfolio from any credit risk that might arise should the domestic economy weaken.

The average maturity of the Fund was similar to the Intermediate Index throughout the first half. The Fund does not emphasize market volatility, but seeks to achieve superior returns by compounding incremental income over market cycles.

An additional component of the Fund’s low risk profile is to highly diversify portfolio holdings. In general, new investment positions are kept to one-half of one percent of the Fund’s value. At the end of June, 159 corporate issuers were held with an average weighting of 0.38% of the Fund’s value.

For the six months ended June 30, 2014, the Mid-Term Bond Fund returned 3.10% before expenses and 2.86% after expenses, versus a 2.25% return for the Barclays Capital Intermediate Government/Credit Bond Index. The Fund’s emphasis on higher-yielding corporate issues was a major contributor to its outperformance

11

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 emphasize low short-term rates in order to stimulate the economy, re-liquefy the banking system and support the mortgage market. As an example, 30-Day Treasury Bill yields ended 2013 at one basis point and remained at that level on June 30, 2014. One year Treasury Bills were also little changed, starting at 16 basis points and ending at 15 basis points in June.

Intermediate and longer dated issues declined during the recent six months in response to Federal Reserve intervention in the market. For example, seven year Treasury Notes declined from 2.45% to 2.14%. Similarly, 30 year Treasury Bonds ended 2013 at 3.97% and declined to 3.36%. As a result, the broad bond market indices registered positive returns for the first half of 2014.

Yield spreads between corporate and Treasury Bonds continued to narrow as investors sought securities with higher yields. This emphasis on income and the resulting capital gains enabled the High Grade bond market to outperform the High Yield market by 31 basis points on a total return basis, according to data provided by CreditSights. On average, “BBB” corporate bonds returned 7.09%, a favorable comparison to the “A” rated average of 5.15% and the “BB” average of 5.99%

The Bond Fund’s strategy was to maintain a similar maturity profile to the Aggregate Index with an overweighting of BBB issuers. Intermediate maturities were emphasized, as was diversification. This was done to protect the Fund from unexpected credit events, so few holdings exceeded one-half of one percent of the Fund’s value. The extreme diversification proved unnecessary, but will be maintained going forward as part of our risk control.

For the six months ended June 30, 2014, the Bond Fund returned 5.08% before expenses and 4.84% after expenses. This compares favorably to the Barclays Capital U.S. Aggregate Bond Index, which returned 3.93% for the period. The Fund’s emphasis on higher-yielding corporate issues was a major contributor to its outperformance.

MUTUAL OF AMERICA INVESTMENT CORPORATION

EXPENSE EXAMPLE (Unaudited)

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 January 1, 2014 and held for the entire period ending June 30, 2014.

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.

MUTUAL OF AMERICA INVESTMENT CORPORATION

NOTES TO FINANCIAL STATEMENTS (Unaudited)

June 30, 2014

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 June 30, 2014, there were 24 active 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 Bond 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, 2045 Retirement Fund and 2050 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 (other than the 2050 Retirement Fund) commenced operations on November 5, 2007. The 2050 Retirement Fund commenced operations on October 1, 2012.

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 Retirement Funds and Allocation Funds.

The preparation of financial statements in accordance with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, income, expenses and related disclosures. Changes in the economic environment, financial markets and any other parameters used in determining these estimates could cause actual results to differ.

The following is a summary of the significant accounting policies consistently followed by the Investment Company, which are in conformity with 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. These inputs are summarized in the three broad levels listed below:

• 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 June 30, 2014 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 are considered Level 3; however, there were no such securities as of June 30, 2014. Fair value inputs for all debt securities were considered Level 2. The inputs or methodologies used for valuing securities are not necessarily an indication of the risk associated with investing in those securities. Transfers between levels are reflected based on the fair value at the beginning of a reporting period.

* Other financial instruments are derivative instruments not reflected in the Portfolio of Investments, such as futures, which are valued at the unrealized appreciation/depreciation on the instrument.

During the six months ended June 30, 2014, there were no transfers of securities between Level 1, Level 2, or Level 3.

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

Exchange-traded equity securities are valued at the last reported 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. The Adviser’s valuation is primarily based on information regarding the specific equity issuer, such as the last trade price, financial statements, the relationship of per-share book value to the last trade price, operating information and any corporate actions, such as dividends or returns of capital, that may have occurred since the last trade. 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. Generally, absent any significant contrary indications, the last trade price will be used as the calculated fair value.

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

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 equity securities 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 appreciation or depreciation by “marking-to-market” on a daily basis to reflect the market value of the contract at the end of each trading day. The accumulated unrealized appreciation or depreciation on the contract is included in Net Unrealized Appreciation (Depreciation) of Investments and Futures Contracts in the Components of Net Assets section of the Statements 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 appreciation or depreciation are incurred, variation margin payments are received or made daily. The net change in unrealized appreciation or depreciation of futures contracts is recorded in the Statements of Operations. When the contract is closed, a realized gain or loss from futures transactions is recorded in the Statements 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 “Footnotes 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 six months ended June 30, 2014, the Equity Index Fund, Mid-Cap Equity Index Fund and the All America Fund purchased futures contracts with total principal amounts of $217,810,643, $101,619,014 and $17,382,675, 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

Generally, rebalancing of the Allocation Funds’ holdings is performed on a periodic basis.

Change in Target Investments — During the year, the Retirement Funds listed below had changes to their target investments. Additionally, each of the Allocation Funds had added the International Fund as an equity fund investment during the period. The Conservative Allocation Fund had also added the Mid-Cap Equity Index Fund as an equity fund investment during the period. Overall increases (decreases) to the target percentages were as follows:

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 and are made at least annually. It is the Investment Company’s policy to make distributions of its net investment income and 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 June 30, 2014, 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.

2. EXPENSES

The Investment Company has an Investment Advisory Agreement with Mutual of America Capital Management LLC (“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 of the value of the net assets of each fund, at the following annual rates:

Fund	Annual Investment Management Fee
Retirement Funds		.05	%
Equity Index, Mid-Cap Equity Index, International Funds		.075	%
Money Market Fund		.15	%
Bond Fund		.39	%
All America, Composite, Mid-Term Bond Funds		.40	%

The Adviser does not assess a fee for investment management to the Allocation Funds. However, shareholders in the Allocation Funds (and the Retirement and International Funds) will indirectly bear their pro-rata share of the investment management fees incurred by the underlying Funds in which they invest.

The difference between the components of distributable earnings for income tax purposes and the amounts reflected in the statements of assets and liabilities arise primarily from federal income tax treatment of wash sales, REITs, partnerships, corporate actions and futures contracts.

Reclassifications — The Funds make adjustments to the components of net assets for book to tax differences that are considered permanent in nature. For the six months ended June 30, 2014, the Funds reclassified amounts primarily relating to differences in the book to tax treatment of partnership investments, REITs, net operating losses and the character of distributions. Each Fund’s net assets are not affected by these reclassifications.

During the six months ended June 30, 2014, each Fund reclassified the following book to tax differences [increases (decreases)]:

	Equity Index Fund			All America Fund			Small Cap Value Fund			Small Cap Growth Fund			Mid Cap Value Fund

Renewal of Investment Advisory Agreements

At its meeting held on February 25, 2014, the Board of Directors of the Investment Company renewed for a one-year period the investment advisory agreement with Mutual of America Capital Management LLC (the “Adviser”). The Board determined that renewing the agreement with the Adviser was in the best interest of the Investment Company based on the following considerations which are further enumerated below. The Board concluded that Mutual of America Capital Management LLC has performed extensive services for the Investment Company and has demonstrated satisfactory performance, that its fee is reasonable in comparison to fees charged for similar services to similar funds by other advisers, that the method of calculating the fee is reasonable, that the Adviser has not made excessive profits from the contract and the fee levels reflect that the Funds are appropriately benefiting from economies of scale.

Nature, Extent and Quality of Services

The Board considered the depth of experience and organizational structure of the Adviser. At December 31, 2013, the Adviser had approximately $13 billion of assets under management. The individual portfolio managers that oversee the investment performance of each of the Investment Company’s Funds have extensive experience and knowledge of the specific markets in which they participate. The Adviser adheres to a strict best execution policy which requires it to select broker/dealers based on their ability to execute trades at a favorable and reasonable price. All else being equal, the Advisor will also consider any research that the broker/dealers may provide. The Adviser maintains a highly qualified staff of research analysts and quantitative analysts who assist in the implementation of the disciplined investment policies employed by the portfolio managers to enhance stock selection and manage risk in the portfolios. The Adviser’s quantitative analysts have developed proprietary models that result in daily risk and attribution reports as well as information on stock movements, to enable the portfolio managers to make fully informed decisions on stock selection and to constantly evaluate the structure of each portfolio. When purchasing research and other services, the

99

Adviser uses its own funds to purchase such services from recognized firms that are utilized by the research staff. The Adviser also receives research services from broker/dealers which are utilized to benefit the Funds. The Board was aware of the receipt of these research services when it considered renewing the advisory agreement with the Adviser. The Adviser, at no cost, provides services beyond those set forth in the advisory agreement, such as assistance in the preparation of marketing materials and attendance at client and prospect meetings.

Investment Performance

The Board considered the short- and long-term performance of the Funds. During 2013, the vast majority of the Funds demonstrated gross performance that was above their benchmarks, when considering minimal tracking error. Performance has continued to improve over the past number of years due to changes made in the Adviser’s investment process and personnel, including the creation of the quantitative research group mentioned above.

Cost and Profit

The Board compared the advisory fees charged to each Fund by the Adviser with fees of numerous similar funds. In the case of each Fund, the Adviser’s fee compared favorably with fees charged by other advisers. Finally, the Adviser has not shown excessively high profits from the fees it is paid by the Investment Company.

Economies of Scale

The Board concluded that the reasonableness of the Adviser’s fees, particularly when compared to fees of similar funds that, in most cases, are many times the asset size of the Funds of the Investment Company demonstrates the fact that the Funds are benefiting from economies of scale. The Adviser utilizes the resources at its disposal efficiently. Its fees reflect cost savings and expense discounts, if any, that it realizes from volume increases.

(2) The fund has an arrangement with its custodian bank, JP Morgan Chase Bank, whereby uninvested cash, subject to parameters set by the fund, is automatically invested in the fund’s name by the bank in overnight commercial paper issued by J.P. Morgan Chase & Co. On the next business day, these funds (and earned interest) are automatically returned to the fund. The annual rate of interest earned on this temporary cash investment at June 30, 2014 was 0.15%.

(3) Percentage is less than 0.05%.

(4) U.S. Government guaranteed security.

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. These inputs are summarized in the three broad levels listed below:

• 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 June 30, 2014, 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; however, there were no such securities as of June 30, 2014. 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. Transfers between levels are reflected based on the fair value at the beginning of a reporting period.

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

Exchange-traded equity securities are valued at the last reported 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.

FOOTNOTES TO PORTFOLIOS OF INVESTMENTS IN SECURITIES

June 30, 2014 (Unaudited)

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. The Adviser’s valuation is primarily based on information regarding the specific equity issuer, such as the last trade price, financial statements, the relationship of per-share book value to the last trade price, operating information and any corporate actions, such as dividends or returns of capital, that may have occurred since the last trade. 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. Generally, absent any significant contrary indications, the last trade price will be used to calculate fair value.

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

Investment Transactions — Investment transactions are accounted for as of the trade date. Realized gain and loss 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 equity securities 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 appreciation or depreciation by “marking-to-market” on a daily basis to reflect the market value of the contract at the end of each trading day. The accumulated unrealized appreciation or depreciation on the contract is included in Net Unrealized Appreciation (Depreciation) of Investments and Futures Contracts in the Components of Net Assets section of the Statements 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 appreciation or depreciation are incurred, variation margin payments are received or made daily. The net change in unrealized appreciation or depreciation of futures contracts is recorded in the Statements of Operations. When the contract is closed, a realized gain or loss from futures transactions is recorded in the Statements 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 Portfolios 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.
