Portfolio Turnover [Text Block]	rr_PortfolioTurnoverTextBlock	The Fund pays transaction costs, such as commissions, when it buys and sells securities (or turns over its portfolio). A higher portfolio turnover rate may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 4% of the average value of its portfolio.

Expense Example [Heading]	rr_ExpenseExampleHeading	Expense Example
Expense Example Narrative [Text Block]	rr_ExpenseExampleNarrativeTextBlock	This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds.                The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Strategy [Heading]	rr_StrategyHeading	Principal Investment Strategies
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund invests substantially all of its assets in shares of the Large Cap Equity Index Fund and the Bond Fund. The Fund attempts to maintain approximately 60% of its assets in shares of the Large Cap Equity Index Fund and 40% of its assets in shares of the Bond Fund. The Large Cap Equity Index Fund primarily invests in stocks of issuers that are listed on the S&P 500® Index. The Bond Fund invests primarily in good quality bonds issued by domestic companies.
Risk [Heading]	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	Because the Fund invests substantially all its assets in the Large Cap Equity Index Fund and the Bond Fund, the risks of investing in the Fund are the same as the risks of investing in those underlying funds.                The Fund is subject to market risk associated with the stock and equity investments of the Large Cap Equity Index Fund. Prices of stocks may and frequently do fluctuate widely over short or extended periods in response to company, market, or economic news or events. Stock markets also tend to move in cycles, with periods of rising stock prices and periods of falling stock prices. Periods of falling stock prices are likely to adversely affect the Fund’s net asset value, yield and total return.                The Fund is also subject to interest rate risk and credit risk associated with the bond investments of the Bond Fund. Interest rate risk is the risk that bonds will decline in value because of changes in interest rates. Generally, bonds decrease in value when interest rates rise and increase in value when interest rates fall. Credit risk is the risk that an issuer of a bond may become unable to meet its obligation to pay interest on the bond, or repay principal.                An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. You can lose money by investing in the Fund.                You may want to consider investing in the Fund if you: Are seeking higher potential returns than money market funds and are willing to accept a moderate level of volatility want to diversify your investments are seeking an income mutual fund for an asset allocation program are retired or nearing retirement                You may not want to invest in the Fund if you: are investing for maximum return over a long time horizon require stability of your principal

Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund attempts to remain as fully invested as practicable in a pool of stocks and other equity securities that comprise the EAFE Free in a manner that is expected to approximate the performance of the benchmark index.

Risk [Heading]	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	Investors who purchase shares of the Fund are subject to various risks, and it is possible for you to lose money by investing in the Fund. An investment in this Fund is not a deposit of any bank or other insured depository institution and is not insured or guaranteed by the FDIC or another government agency. An investor in the Fund is subject to the following types of risks: Market Risk.    Stock prices may fluctuate widely over short or even extended periods in response to company, market, or economic news. Stock markets also tend to move in cycles, with periods of rising stock prices and periods of falling stock prices. Foreign Investing Risk.    Investing in foreign securities involves higher trading and custody costs than investing in U.S. companies. Accounting, legal and reporting practices are different than in the U.S. and regulation is often less stringent. Potential political or economic instability presents risks, as does the fluctuation in currency exchange rates, as well as the possible imposition of exchange control regulation or currency restrictions that could prevent the conversion of local currencies into U.S. dollars. Some foreign markets are considered to be emerging market countries. Investments in these countries subject the Fund to a greater risk of loss than investments in a developed country. This is due to, among other things, greater market volatility, lower trading volume, political and economic instability, greater risk of market shut down and more governmental limitations on foreign investment policy than those typically found in a developed market. Management Risk.    The assessment by the Fund’s investment adviser or sub-adviser of the securities to be purchased or sold by the Fund may prove incorrect, resulting in losses or poor performance, even in a rising market. Indexing Risk.    This Fund attempts to match the performance of a securities market index, but there is no guarantee that this Fund will succeed in its attempt to match such performance. Security Selection Risk.    Because securities market indices are developed by persons unrelated to the Fund, the Manager or to the Fund’s sub-adviser, the Fund may hold stocks in companies that present risks that the Manager or the Fund’s sub-adviser researching individual stocks might avoid.                An investment in the Fund may be appropriate for you if you intend to maintain your investment for many years and through multiple stock market cycles. Because of stock market volatility, the Fund may not be a suitable investment if you have a short-term investment horizon or if you are unwilling to accept fluctuations in share price, including significant declines over a given period.

State Farm Stock and Bond Balanced Fund

STOCK AND BOND BALANCED FUND

               Investment Objective:

               The Stock and Bond Balanced Fund (the “Fund”) seeks long-term growth of capital, balanced with current income.

What are the costs of investing in the Fund?

               This table describes the fees and expenses you may pay if you buy and hold shares of the Fund.

Annual Fund Operating Expenses
(expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses	State Farm Stock and Bond Balanced Fund
Management Fees	none
Distribution and Service (12b-1) Fees	none
Other Expenses	0.09%
Acquired Fund Fees and Expenses	0.40%
Total Annual Fund Operating Expenses	0.49%

               Expense Example

               This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds.

               The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example (USD $)	1 Year	3 Years	5 Years	10 Years
State Farm Stock and Bond Balanced Fund	50	157	274	616

               The example does not reflect additional charges and expenses that are described in the prospectuses for the variable deferred annuity and variable universal life insurance policies issued by State Farm Life Insurance Company and State Farm Life and Accident Assurance Company. If those charges and expenses were included, the expenses would be higher.

Portfolio Turnover

               The Fund pays transaction costs, such as commissions, when it buys and sells securities (or turns over its portfolio). A higher portfolio turnover rate may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 4% of the average value of its portfolio.

Principal Investment Strategies

               The Fund invests substantially all of its assets in shares of the Large Cap Equity Index Fund and the Bond Fund. The Fund attempts to maintain approximately 60% of its assets in shares of the Large Cap Equity Index Fund and 40% of its assets in shares of the Bond Fund. The Large Cap Equity Index Fund primarily invests in stocks of issuers that are listed on the S&P 500® Index. The Bond Fund invests primarily in good quality bonds issued by domestic companies.

Principal Risks of Investing in the Fund

               Because the Fund invests substantially all its assets in the Large Cap Equity Index Fund and the Bond Fund, the risks of investing in the Fund are the same as the risks of investing in those underlying funds.

               The Fund is subject to market risk associated with the stock and equity investments of the Large Cap Equity Index Fund. Prices of stocks may and frequently do fluctuate widely over short or extended periods in response to company, market, or economic news or events. Stock markets also tend to move in cycles, with periods of rising stock prices and periods of falling stock prices. Periods of falling stock prices are likely to adversely affect the Fund’s net asset value, yield and total return.

               The Fund is also subject to interest rate risk and credit risk associated with the bond investments of the Bond Fund. Interest rate risk is the risk that bonds will decline in value because of changes in interest rates. Generally, bonds decrease in value when interest rates rise and increase in value when interest rates fall. Credit risk is the risk that an issuer of a bond may become unable to meet its obligation to pay interest on the bond, or repay principal.

               An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. You can lose money by investing in the Fund.

               You may want to consider investing in the Fund if you:

• Are seeking higher potential returns than money market funds and are willing to accept a moderate level of volatility

• want to diversify your investments

• are seeking an income mutual fund for an asset allocation program

• are retired or nearing retirement

               You may not want to invest in the Fund if you:

• are investing for maximum return over a long time horizon

• require stability of your principal

Investment Results

               The following bar chart and table illustrate certain risks of investing in the Fund by showing changes in the Fund’s performance from year to year. This information is intended to help you assess the variability of the Fund’s returns over the periods listed to a measure of market performance (and consequently, the potential returns and risks of an investment in the Fund).

               The Fund’s past performance doesn’t necessarily indicate how it will perform in the future.

Annual Total Returns For Calendar Years

               The Fund’s best and worst quarters during the periods in the bar chart were:

Best quarter: 11.29%,
               during the second quarter of 2009.

Worst quarter: -12.51%,
               during the fourth quarter of 2008.

               The following table shows the Average Annual Total Returns on an investment in the Fund compared to changes in the S&P 500® Index and Barclays Capital Government/Credit Intermediate Index for the 1, 5 and 10-year periods ended 12/31/2012. SFIM computes the Blended Benchmark by using 60% S&P 500® Index and 40% Barclays Capital Government/Credit Intermediate Index.

Portfolio Turnover [Text Block]	rr_PortfolioTurnoverTextBlock	The Fund pays transaction costs, such as commissions, when it buys and sells securities (or turns over its portfolio). A higher portfolio turnover rate may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 92% of the average value of its portfolio.

Strategy [Heading]	rr_StrategyHeading	Principal Investment Strategies
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	Two different investment sub-advisers, Bridgeway Capital Management, Inc. (“Bridgeway”) and Rainier Investment Management, Inc. (“Rainier”), select investments for the Small/Mid Cap Equity Fund. Bridgeway and Rainier each manage approximately one-half of the Small/Mid Cap Equity Fund’s portfolio. State Farm Investment Management Corp. (the “Manager” or “SFIM”) monitors the performance of the sub-advisers and the allocation of the portfolio between the sub-advisers. The principal investment strategies employed by the two sub-advisers for their respective portions of the portfolio are discussed separately below. Bridgeway                Bridgeway primarily invests its segment of the Fund in a diversified portfolio of small and mid-capitalization stocks. Bridgeway defines “small stocks” as those whose market capitalization (stock market value) falls within the range of the Russell 2000 Index, an unmanaged, market value weighted index, which measures performance of the 2,000 companies that are between the 1,000th and 3,000th largest in the market with dividends reinvested. The Russell 2000 Index is reconstituted from time to time. The market capitalization of companies in which Bridgeway may invest may vary with market conditions. Bridgeway selects stocks using a statistically driven approach.                Bridgeway invests in small and mid-capitalization stocks in the “value” category, which it defines as those stocks that Bridgeway believes are priced cheaply relative to some financial measures of worth, such as the ratio of price to earnings, price to sales or price to cash flow. At least 80% of Bridgeway’s portion of the Fund’s net assets (plus borrowings for investment purposes) is invested in stocks from among those in the small cap value category at the time of purchase. However, Bridgeway will not necessarily sell a stock if it “migrates” to a different category after purchase.                Bridgeway may invest up to 10% of its segment of the Fund’s assets primarily in common stocks of foreign companies.                Bridgeway may sell individual securities for several reasons including: the investment purpose of the security has been achieved, fundamental deterioration of company prospects, or better alternatives exist. Securities may also be sold based upon tax considerations, liquidity needs or other portfolio management considerations. Rainier                Rainier invests its segment of the Fund primarily (at least 80%) in the common stock of mid-capitalization companies traded in the U.S. with prospects of strong earnings growth and attractive overall business fundamentals, selling at reasonable valuations. Rainier considers a mid-capitalization company as one with market capitalization, at the time of purchase, within the range of companies included in the Russell Midcap® Index, an index that includes the smallest 800 securities in the Russell 1000® Index.                The portfolio managed by Rainier will invest in a blend of stocks with both growth and value characteristics. In selecting common stock for purchase by the Small/Mid Cap Equity Fund, Rainier emphasizes companies that it believes are likely to demonstrate superior business growth relative to their peers and whose equities are selling at attractive relative valuations.                Rainier may invest up to 20% of its segment of the Fund’s assets primarily in common stocks and depositary receipts of foreign companies.                Rainier considers the sale of specific common stock when fundamentals deteriorate; when a stock reaches or surpasses its price target; or when better opportunities are perceived in alternative stocks.
Risk [Heading]	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	Investors who purchase shares of the Fund are subject to various risks, and it is possible for you to lose money by investing in the Fund. An investment in this Fund is not a deposit of any bank or other insured depository institution and is not insured or guaranteed by the FDIC or another government agency. An investor in the Fund is subject to the following types of risks: Market Risk.    Stock prices may fluctuate widely over short or even extended periods in response to company, market, or economic news. Stock markets also tend to move in cycles, with periods of rising stock prices and periods of falling stock prices. Foreign Investing Risk.    Investing in foreign securities involves higher trading and custody costs than investing in U.S. companies. Accounting, legal and reporting practices are different than in the U.S. and regulation is often less stringent. Potential political or economic instability presents risks, as does the fluctuation in currency exchange rates, as well as the possible imposition of exchange control regulation or currency restrictions that could prevent the conversion of local currencies into U.S. dollars. Some foreign markets are considered to be emerging market countries. Investments in these countries subject the Fund to a greater risk of loss than investments in a developed country. This is due to, among other things, greater market volatility, lower trading volume, political and economic instability, greater risk of market shut down and more governmental limitations on foreign investment policy than those typically found in a developed market. Management Risk.    The assessment by the Fund’s investment adviser or sub-adviser of the securities to be purchased or sold by the Fund may prove incorrect, resulting in losses or poor performance, even in a rising market. Smaller Company Size Risk.    The securities of smaller capitalization companies are often more difficult to value or dispose of, more difficult to obtain information about, and more volatile than stocks of larger, more established companies. In addition, the markets for the Fund’s investments may not be actively traded, which increases the risk that the Fund’s investment adviser or sub-adviser may have difficulty selling securities the Fund holds.                An investment in the Fund may be appropriate for you if you intend to maintain your investment for many years and through multiple stock market cycles. Because of stock market volatility, the Fund may not be a suitable investment if you have a short-term investment horizon or if you are unwilling to accept fluctuations in share price, including significant declines over a given period.

The Russell 2500® Index measures the performance of the 2,500 smallest securities in the Russell 3000® Index, which represents approximately 20% of the total market capitalization of the Russell 3000® Index. Unlike an investment in the Small/Mid Cap Equity Fund, a theoretical investment in the Index does not reflect any expenses. It is not possible to invest directly in an index.                The Fund’s inception date is August 1, 2005.

Strategy [Heading]	rr_StrategyHeading	Principal Investment Strategies
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	Two different investment sub-advisers, Marsico Capital Management, LLC (“Marsico”) and Northern Cross, LLC (“Northern Cross”), select investments for the International Equity Fund. Marsico and Northern Cross each manage approximately one-half of the International Equity Fund’s portfolio. State Farm Investment Management Corp. (the “Manager” or “SFIM”) monitors the performance of the sub-advisers and the split of the portfolio between the sub-advisers. The principal investment strategies employed by the two sub-advisers for their respective portions of the portfolio are discussed separately below. Marsico                Marsico invests its portion of the International Equity Fund primarily in common stock of foreign companies that it selects for their long-term growth potential. Marsico may invest its portion of the International Equity Fund in an unlimited number of companies of any size throughout the world, and normally invests in the securities of issuers that are economically tied to at least four different foreign countries. The Fund may invest in securities of companies economically tied to emerging markets. Some issuers of securities in the Fund’s portfolio may be based in or economically tied to the U.S. In selecting investments for the Fund, Marsico uses an approach that combines ‘top-down’ macro-economic analysis that focuses on broad financial and economic indicators with ‘bottom-up’ stock selection that initially focuses on individual stocks.                Marsico may sell individual securities for several reasons including: price target of the security has been achieved, fundamental deterioration of company prospects, or better alternatives exist. Securities may also be sold based upon tax considerations, liquidity needs or other portfolio management considerations. Northern Cross                Northern Cross invests its portion of the International Equity Fund in securities issued by foreign companies in which it believes have the potential for long term margin expansion. Northern Cross primarily focuses on common stocks priced cheaply relative to some financial measure of worth, such as ratios of price to earnings, price to sales or price to cash flow. Under normal market conditions Northern Cross will invest its portion of the International Equity Fund in 60-80 companies with a diversified representation of sectors. In selecting securities for the International Equity Fund, Northern Cross gives careful consideration to currency, political stability and other effects of international investing.                Northern Cross may sell individual securities for several reasons including: full valuation of the security has been achieved, fundamental deterioration of company prospects, or better alternatives exist. Securities may also be sold based upon tax considerations, liquidity needs or other portfolio management considerations.

State Farm Bond Fund

BOND FUND

               Investment Objective:

               The Bond Fund (the “Fund”) seeks to realize over a period of years the highest yield consistent with prudent investment management through current income and capital gains.

What are the costs of investing in the Fund?

               This table describes the fees and expenses you may pay if you buy and hold shares of the Fund.

Annual Fund Operating Expenses
(expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses	State Farm Bond Fund
Management Fees	0.50%
Distribution and Service (12b-1) Fees	none
Other Expenses	0.08%
Acquired Fund Fees and Expenses	none
Total Annual Fund Operating Expenses	0.58%

               Expense Example

               This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds.

               The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example (USD $)	1 Year	3 Years	5 Years	10 Years
State Farm Bond Fund	59	186	324	726

               The example does not reflect additional charges and expenses that are described in the prospectuses for the variable deferred annuity and variable universal life insurance policies issued by State Farm Life Insurance Company and State Farm Life and Accident Assurance Company. If those charges and expenses were included, the expenses would be higher.

Portfolio Turnover

               The Fund pays transaction costs, such as commissions, when it buys and sells securities (or turns over its portfolio). A higher portfolio turnover rate may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 8% of the average value of its portfolio.

Principal Investment Strategies

               The Bond Fund invests primarily in investment grade bonds issued by U.S. companies, U.S. government and agency obligations, and mortgage backed securities. Under normal circumstances, the Bond Fund invests at least 80% of its net assets plus any borrowings in investment grade bonds or in bonds that are not rated, but that State Farm Investment Management Corp. (“SFIMC” or the “Manager”) has determined to be of comparable quality. A bond is investment grade if Moody’s Investors Service, Inc. (“Moody’s”) or S&P has rated the bond in one of their respective four highest rating categories. Non-investment grade bonds are commonly referred to as “junk bonds.” The Bond Fund may invest in any of the following instruments:               

• Corporate Debt Securities: investment grade securities issued by corporations and to a limited extent (up to 20% of its assets), in lower rated securities

• U.S. Government Debt Securities: securities issued or guaranteed by the U.S. Government or its agencies or instrumentalities

• Foreign Government Debt Securities: investment grade securities issued or guaranteed by a foreign government or its agencies or instrumentalities, payable in U.S. dollars

• Asset Backed and Mortgage Backed Securities: investment grade securities backed by mortgages, consumer loans and other assets

• Other Issuer Debt Securities: the Fund may invest up to 20% of its assets in non-investment grade debt securities and preferred stocks that are convertible into common stocks as well as nonconvertible preferred stocks or securities.

               The Manager may sell individual securities for several reasons including: price target of the security has been achieved, fundamental deterioration of company prospects, or better alternatives exist. Securities may also be sold based upon tax considerations, liquidity needs or other portfolio management considerations.

Principal Risks of Investing in the Fund

               Investors who purchase shares of the Fund are subject to various risks, and it is possible for you to lose money by investing in the Fund. An investment in this Fund is not a deposit of any bank or other insured depository institution and is not insured or guaranteed by the FDIC or another government agency. An investor in the Fund is subject to the following types of risks:

• Management Risk.    The assessment by the Fund’s investment adviser of the securities to be purchased or sold by the Fund may prove incorrect, resulting in losses or poor performance, even in a rising market.

• Interest Rate Risk and Call Risk.    The risk that the bonds the Fund holds may decline in value due to an increase in interest rates. All bonds, including those issued by the U.S. Government, are subject to interest rate risk. Bonds with longer maturities are affected more by interest rate movements than bonds with shorter maturities. Another risk associated with interest rate changes is call risk. Call risk is the risk that during periods of falling interest rates, a bond issuer will “call” or repay a higher yielding bond before the maturity date of the bond. Under these circumstances, the Fund may have to reinvest the proceeds in an investment that provides a lower yield than the called bond.

• Prepayment and Extension Risk.    The risk that homeowners or consumers may alter the pace of repayment on their mortgage or consumer loans, which may affect the yield of mortgage-or asset-backed securities that are backed by such loans.

• Credit Risk.    The risk that a bond issuer fails to make principal or interest payments when due to the Fund, or that the credit quality of the issuer falls. Corporate bonds are subject to greater credit risk than U.S. Government bonds.

• High Yield, High Risk Securities.    Bonds that are in low or below investment-grade categories, or are unrated at the time of purchase (sometimes referred to as “junk bonds” or high yield securities) have a greater risk of default and are more volatile than higher-rated securities of similar maturity. The value of these securities is affected by overall economic conditions, interest rates, and the creditworthiness of the individual issuers. Additionally, these lower-rated or unrated bonds may be less liquid and more difficult to value than higher-rated securities.

• Liquidity Risk.    The investment adviser to the Fund may have difficulty selling securities the Fund holds at the time it would like to sell, and at the value the Fund has placed on those securities.

• Income Risk.    The risk that the income from the bonds the Fund holds will decline in value due to falling interest rates.

               You may want to invest in the Fund if you are seeking higher potential returns than money market funds and are willing to accept the price volatility of bonds with longer maturities, want to diversify your investments, are seeking an income mutual fund for an asset allocation program or are retired or nearing retirement. You may not want to invest in the Fund if you are investing for maximum return over a long time horizon, want the greater growth potential of an investment in equity securities or require stability of your principal.

Investment Results

               The following bar chart and table illustrate certain risks of investing in the Fund by showing changes in the Fund’s performance from year to year. This information is intended to help you assess the variability of the Fund’s returns over the periods listed to a measure of market performance (and consequently, the potential returns and risks of an investment in the Fund).

               The Fund’s past performance doesn’t necessarily indicate how it will perform in the future.

Annual Total Returns For Calendar Years

               The Fund’s best and worst quarters during the periods in the bar chart were:

Best quarter: 5.16%,
               during the second quarter of 2009.

Worst quarter: -2.27%,
               during the second quarter of 2004.

               The following table shows the Average Annual Total Returns on an investment in the Fund compared to changes in the Barclays Capital Government/Credit Intermediate Index for the 1, 5 and 10-year periods ended 12/31/2012. The Barclays Capital Government/Credit Intermediate Index includes U.S. Government and corporate bonds maturing within one to ten years and an outstanding par value of at least $250 million.

Strategy [Heading]	rr_StrategyHeading	Principal Investment Strategies
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	Two different investment sub-advisers, Bridgeway Capital Management, Inc. (“Bridgeway”) and Westwood Management Corp. (“Westwood”), select investments for the Large Cap Equity Fund. Bridgeway and Westwood each manage approximately one-half of the Large Cap Equity Fund’s portfolio. State Farm Investment Management Corp. (the “Manager” or “SFIM”) monitors the performance of the sub-advisers and the allocation of the portfolio between the sub-advisers. The principal investment strategies employed by the two sub-advisers for their respective portions of the portfolio are discussed separately below. Bridgeway                Bridgeway primarily invests its portion of the Large Cap Equity Fund in a diversified portfolio of large growth stocks. Bridgeway defines “large stocks” as those whose market capitalization (stock market worth) falls within the range of the Russell 1000 Index, an unmanaged, market value weighted index, which measures performance of approximately 1,000 of the largest companies in the market with dividends reinvested. The Russell 1000 Index is reconstituted from time to time. The market capitalization of companies in which Bridgeway may invest may vary with market conditions. Growth stocks are those that Bridgeway believes have above average prospects for economic growth. Bridgeway selects stocks within the large-cap growth category for the Large Cap Equity Fund using a statistically driven approach. At least 80% of Bridgeway’s portion of the Large Cap Equity Fund’s net assets (plus borrowings for investment purposes) are invested in stocks from among those in the large-cap growth category at the time of purchase. However, Bridgeway will not necessarily sell a stock if it “migrates” to a different category after purchase. Westwood                Under normal market conditions, Westwood invests at least 80% of its portion of the Large Cap Equity Fund (which includes, for purposes of this test, the amount of any borrowings for investment purposes) primarily in common stocks of large capitalization companies, including foreign companies. Westwood invests in a portfolio of seasoned companies utilizing a value style of investing in which it chooses those stocks that Westwood believes have earnings prospects that are currently undervalued by the market relative to some financial measure of worth, such as the ratio of price to earnings, price to sales or price to cash flow. Westwood defines large capitalization companies as those companies with market capitalizations greater than $5 billion at the time of purchase, while seasoned companies generally have been operating for at least three years.                In selecting securities, Westwood maintains a list of approved securities of issuers which it believes have proven records and potential for above-average earnings growth. Westwood considers purchasing a security on such list if Westwood’s forecast for growth rates and earnings for that issuer exceeds Wall Street expectations. Other key metrics for evaluating the risk/return profile of an investment include an improving return on equity, a declining debt to equity ratio and, in the case of common equities, positive earnings surprises without a corresponding increase in Wall Street estimates. Westwood has disciplines in place that serve as sell signals, such as a security reaching a pre-determined price target, and/or a fundamental change that negatively impacts the outlook and original investment thesis. The investment team will also review a stock if the price of the stock declines 15% or more in the first 45 days held. The risk characteristics of Westwood’s portion of the Large Cap Equity Fund, such as beta (a measure of volatility), are generally expected to be less than those of the S&P 500, the Fund’s benchmark.                Both Bridgeway and Westwood may sell individual securities for several reasons including: price target of the security has been achieved, fundamental deterioration of company prospects, or better alternatives exist. Securities may also be sold based upon tax considerations, liquidity needs or other portfolio management considerations.
Risk [Heading]	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	Investors who purchase shares of the Large Cap Equity Fund are subject to various risks, and it is possible for you to lose money by investing in the Fund. An investment in this Fund is not a deposit of any bank or other insured depository institution and is not insured or guaranteed by the Federal Deposit Insurance Corporation (the “FDIC”) or another government agency. An investor in the Fund is subject to the following types of risks: Market Risk.    Stock prices may fluctuate widely over short or even extended periods in response to company, market, or economic news. Stock markets also tend to move in cycles, with periods of rising stock prices and periods of falling stock prices. Foreign Investing Risk.    Investing in foreign securities involves higher trading and custody costs than investing in U.S. companies. Accounting, legal and reporting practices are different than in the U.S. and regulation is often less stringent. Potential political or economic instability presents risks, as does the fluctuation in currency exchange rates, as well as the possible imposition of exchange control regulation or currency restrictions that could prevent the conversion of local currencies into U.S. dollars. Some foreign markets are considered to be emerging market countries. Investments in these countries subject the Fund to a greater risk of loss than investments in a developed country. This is due to, among other things, greater market volatility, lower trading volume, political and economic instability, greater risk of market shut down and more governmental limitations on foreign investment policy than those typically found in a developed market. Management Risk.    The assessment by the Fund’s investment adviser or sub-adviser of the securities to be purchased or sold by the Fund may prove incorrect, resulting in losses or poor performance, even in a rising market.               An investment in the Fund may be appropriate for you if you intend to maintain your investment for many years and through multiple stock market cycles. Because of stock market volatility, the Fund may not be a suitable investment if you have a short-term investment horizon or if you are unwilling to accept fluctuations in share price, including significant declines over a given period.

State Farm Large Cap Equity Index Fund

LARGE CAP EQUITY INDEX FUND

               Investment Objective:

               The Large Cap Equity Index Fund (the “Fund”) seeks to match performance of the S&P^® 500 Index (the “S&P 500”) by investing in the securities that make up the S&P 500.

What are the costs of investing in the Fund?

               This table describes the fees and expenses you may pay if you buy and hold shares of the Fund.

Annual Fund Operating Expenses
(expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses	State Farm Large Cap Equity Index Fund
Management Fees	0.24%
Distribution and Service (12b-1) Fees	none
Other Expenses	0.05%
Acquired Fund Fees and Expenses	none
Total Annual Fund Operating Expenses	0.29%

               Expense Example

               This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds.

               The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example (USD $)	1 Year	3 Years	5 Years	10 Years
State Farm Large Cap Equity Index Fund	30	93	163	368

               The example does not reflect additional charges and expenses that are described in the prospectuses for the variable deferred annuity and variable universal life insurance policies issued by State Farm Life Insurance Company and State Farm Life and Accident Assurance Company. If those charges and expenses were included, the expenses would be higher.

Portfolio Turnover

               The Fund pays transaction costs, such as commissions, when it buys and sells securities (or turns over its portfolio). A higher portfolio turnover rate may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 4% of the average value of its portfolio.

Principal Investment Strategies

               The Fund seeks to achieve investment performance that is similar to the S&P 500 Index (the Fund’s target benchmark). The S&P 500 Index is a widely used measure of large U.S. company stock performance. Standard & Poor’s (“S&P”) selects stocks for the S&P 500 Index based upon the following factors:

• market value

• industry group classification (so that the S&P 500 Index represents a broad range of industry segments within the U.S. economy)

• trading activity, to ensure ample liquidity and efficient share pricing

• fundamental analysis, to ensure that companies in the S&P 500 Index are stable

                The Fund pursues its investment objective by:

• investing in substantially all of the securities that make up the S&P 500 Index

• investing in these securities in proportions that match, approximately, the weightings of the S&P 500 Index

                Under normal operating conditions, the Fund seeks to invest at least 90% of its total assets in stocks that are represented in the S&P 500 Index.

                BlackRock Fund Advisors (“BFA”), the sub-adviser to the Fund, may sell securities to reflect security changes within the index or to balance the portfolio to the index. Securities may also be sold based upon tax considerations, liquidity needs or other portfolio management considerations.

Principal Risks of Investing in the Fund

               Investors who purchase shares of the Fund are subject to various risks, and it is possible for you to lose money by investing in the Fund. An investment in this Fund is not a deposit of any bank or other insured depository institution and is not insured or guaranteed by the Federal Deposit Insurance Corporation (“FDIC”) or another government agency. An investor in the Fund is subject to the following types of risks:

• Market Risk.    Stock prices may fluctuate widely over short or even extended periods in response to company, market, or economic news. Stock markets also tend to move in cycles, with periods of rising stock prices and periods of falling stock prices.

• Management Risk.    The assessment by the Fund’s investment adviser or sub-adviser of the securities to be purchased or sold by the Fund may prove incorrect, resulting in losses or poor performance, even in a rising market.

• Indexing Risk.     This Fund attempts to match the performance of a securities market index, but there is no guarantee that this Fund will succeed in its attempt to match such performance.

• Security Selection Risk.    Because securities market indices are developed by persons unrelated to the Fund, State Farm Investment Management Corp. (“SFIMC” or the “Manager”) or to the Fund’s sub-adviser, the Fund may hold stocks in companies that present risks that the Manager or the Fund’s sub-adviser researching individual stocks might avoid.

                An investment in the Fund may be appropriate for you if you intend to maintain your investment for many years and through multiple stock market cycles. Because of stock market volatility, the Fund may not be a suitable investment if you have a short-term investment horizon or if you are unwilling to accept fluctuations in share price, including significant declines over a given period.

Investment Results

               The following bar chart and table illustrate certain risks of investing in the Fund by showing changes in the Fund’s performance from year to year. This information is intended to help you assess the variability of the Fund’s returns over the periods listed to a measure of market performance (and consequently, the potential returns and risks of an investment in the Fund).

               The Fund’s past performance doesn’t necessarily indicate how it will perform in the future.

Annual Total Returns For Calendar Years

               The Fund’s best and worst quarters during the periods in the bar chart were:

Best quarter: 15.80%,
                during the second quarter of 2009.

Worst quarter: -21.87%,
               during the fourth quarter of 2008.

               The following table shows the Average Annual Total Returns on an investment in the Fund compared to changes in the S&P 500 for the 1, 5 and 10-year periods ended 12/31/2012. The S&P 500 Index is a capitalization-weighted measure of the common stocks of 500 large U.S. companies. The S&P 500 Index represents an unmanaged group of stocks that differ from the composition of the Large Cap Equity Index Fund.

Average Annual Total Returns
(for the periods ended December 31, 2012)

Average Annual Total Returns	1 Year	5 Year	10 Year
State Farm Large Cap Equity Index Fund	15.72%	1.39%	6.79%

State Farm Small Mid Cap Equity Fund

SMALL/MID CAP EQUITY FUND

               Investment Objective:

               The Small/Mid Cap Equity Fund (or the “Fund”) seeks long-term growth of capital.

What are the costs of investing in the Fund?

               This table describes the fees and expenses you may pay if you buy and hold shares of the Fund.

Annual Fund Operating Expenses
(expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses	State Farm Small Mid Cap Equity Fund
Management Fees	0.80%
Distribution and Service (12b-1) Fees	none
Other Expenses	0.16%
Acquired Fund Fees and Expenses	0.02%
Total Annual Fund Operating Expenses	0.98%

               Expense Example

               This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds.

               The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example (USD $)	1 Year	3 Years	5 Years	10 Years
State Farm Small Mid Cap Equity Fund	100	312	542	1,201

               The example does not reflect additional charges and expenses that are described in the prospectuses for the variable deferred annuity and variable universal life insurance policies issued by State Farm Life Insurance Company and State Farm Life and Accident Assurance Company. If those charges and expenses were included, the expenses would be higher.

Portfolio Turnover

               The Fund pays transaction costs, such as commissions, when it buys and sells securities (or turns over its portfolio). A higher portfolio turnover rate may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 92% of the average value of its portfolio.

Principal Investment Strategies

               Two different investment sub-advisers, Bridgeway Capital Management, Inc. (“Bridgeway”) and Rainier Investment Management, Inc. (“Rainier”), select investments for the Small/Mid Cap Equity Fund. Bridgeway and Rainier each manage approximately one-half of the Small/Mid Cap Equity Fund’s portfolio. State Farm Investment Management Corp. (the “Manager” or “SFIM”) monitors the performance of the sub-advisers and the allocation of the portfolio between the sub-advisers. The principal investment strategies employed by the two sub-advisers for their respective portions of the portfolio are discussed separately below.

Bridgeway

               Bridgeway primarily invests its segment of the Fund in a diversified portfolio of small and mid-capitalization stocks. Bridgeway defines “small stocks” as those whose market capitalization (stock market value) falls within the range of the Russell 2000 Index, an unmanaged, market value weighted index, which measures performance of the 2,000 companies that are between the 1,000^th and 3,000^th largest in the market with dividends reinvested. The Russell 2000 Index is reconstituted from time to time. The market capitalization of companies in which Bridgeway may invest may vary with market conditions. Bridgeway selects stocks using a statistically driven approach.

               Bridgeway invests in small and mid-capitalization stocks in the “value” category, which it defines as those stocks that Bridgeway believes are priced cheaply relative to some financial measures of worth, such as the ratio of price to earnings, price to sales or price to cash flow. At least 80% of Bridgeway’s portion of the Fund’s net assets (plus borrowings for investment purposes) is invested in stocks from among those in the small cap value category at the time of purchase. However, Bridgeway will not necessarily sell a stock if it “migrates” to a different category after purchase.

               Bridgeway may invest up to 10% of its segment of the Fund’s assets primarily in common stocks of foreign companies.

               Bridgeway may sell individual securities for several reasons including: the investment purpose of the security has been achieved, fundamental deterioration of company prospects, or better alternatives exist. Securities may also be sold based upon tax considerations, liquidity needs or other portfolio management considerations.

Rainier

               Rainier invests its segment of the Fund primarily (at least 80%) in the common stock of mid-capitalization companies traded in the U.S. with prospects of strong earnings growth and attractive overall business fundamentals, selling at reasonable valuations. Rainier considers a mid-capitalization company as one with market capitalization, at the time of purchase, within the range of companies included in the Russell Midcap^® Index, an index that includes the smallest 800 securities in the Russell 1000^® Index.

               The portfolio managed by Rainier will invest in a blend of stocks with both growth and value characteristics. In selecting common stock for purchase by the Small/Mid Cap Equity Fund, Rainier emphasizes companies that it believes are likely to demonstrate superior business growth relative to their peers and whose equities are selling at attractive relative valuations.

               Rainier may invest up to 20% of its segment of the Fund’s assets primarily in common stocks and depositary receipts of foreign companies.

               Rainier considers the sale of specific common stock when fundamentals deteriorate; when a stock reaches or surpasses its price target; or when better opportunities are perceived in alternative stocks.

Principal Risks of Investing in the Fund

               Investors who purchase shares of the Fund are subject to various risks, and it is possible for you to lose money by investing in the Fund. An investment in this Fund is not a deposit of any bank or other insured depository institution and is not insured or guaranteed by the FDIC or another government agency. An investor in the Fund is subject to the following types of risks:

• Market Risk.    Stock prices may fluctuate widely over short or even extended periods in response to company, market, or economic news. Stock markets also tend to move in cycles, with periods of rising stock prices and periods of falling stock prices.

• Foreign Investing Risk.    Investing in foreign securities involves higher trading and custody costs than investing in U.S. companies. Accounting, legal and reporting practices are different than in the U.S. and regulation is often less stringent. Potential political or economic instability presents risks, as does the fluctuation in currency exchange rates, as well as the possible imposition of exchange control regulation or currency restrictions that could prevent the conversion of local currencies into U.S. dollars. Some foreign markets are considered to be emerging market countries. Investments in these countries subject the Fund to a greater risk of loss than investments in a developed country. This is due to, among other things, greater market volatility, lower trading volume, political and economic instability, greater risk of market shut down and more governmental limitations on foreign investment policy than those typically found in a developed market.

• Management Risk.    The assessment by the Fund’s investment adviser or sub-adviser of the securities to be purchased or sold by the Fund may prove incorrect, resulting in losses or poor performance, even in a rising market.

• Smaller Company Size Risk.    The securities of smaller capitalization companies are often more difficult to value or dispose of, more difficult to obtain information about, and more volatile than stocks of larger, more established companies. In addition, the markets for the Fund’s investments may not be actively traded, which increases the risk that the Fund’s investment adviser or sub-adviser may have difficulty selling securities the Fund holds.

               An investment in the Fund may be appropriate for you if you intend to maintain your investment for many years and through multiple stock market cycles. Because of stock market volatility, the Fund may not be a suitable investment if you have a short-term investment horizon or if you are unwilling to accept fluctuations in share price, including significant declines over a given period.

Investment Results

               The following bar chart and table illustrate certain risks of investing in the Fund by showing changes in the Fund’s performance from year to year. This information is intended to help you assess the variability of the Fund’s returns over the periods listed to a measure of market performance (and consequently, the potential returns and risks of an investment in the Fund).

               The Fund’s past performance doesn’t necessarily indicate how it will perform in the future.

Annual Total Returns For Calendar Years

               The Fund’s best and worst quarters during the periods in the bar chart were:

Best quarter: 19.06%,
               during the second quarter of 2009.

Worst quarter: -29.32%,
               during the fourth quarter of 2008.

               The following table shows the Average Annual Total Returns on an investment in the Fund compared to changes in the Russell 2500^® Index for the 1-year, 5 year and since inception periods ended 12/31/2012. The Russell 2500^® Index measures the performance of the 2,500 smallest securities in the Russell 3000^® Index, which represents approximately 20% of the total market capitalization of the Russell 3000^® Index. Unlike an investment in the Small/Mid Cap Equity Fund, a theoretical investment in the Index does not reflect any expenses. It is not possible to invest directly in an index.

               The Fund’s inception date is August 1, 2005.

               Investment Objective:

               The Money Market Fund (the “Fund”) seeks to maximize current income to the extent consistent with the preservation of capital and maintenance of liquidity.

What are the costs of investing in the Fund?

               This table describes the fees and expenses you may pay if you buy and hold shares of the Fund.

Annual Fund Operating Expenses
(expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses	State Farm Money Market Fund
Management Fees	0.40%
Distribution and Service (12b-1) Fees	none
Other Expenses	0.19%
Acquired Fund Fees and Expenses	0.01%
Total Annual Fund Operating Expenses	0.60%

               Expense Example

               This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds.

               The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example (USD $)	1 Year	3 Years	5 Years	10 Years
State Farm Money Market Fund	61	192	335	750

               The example does not reflect additional charges and expenses that are described in the prospectuses for the variable deferred annuity and variable universal life insurance policies issued by State Farm Life Insurance Company and State Farm Life and Accident Assurance Company. If those charges and expenses were included, the expenses would be higher.

Principal Investment Strategies

               Unlike most other mutual funds, the Fund seeks to maintain a stable net asset value (“NAV”) of $1.00 per share. This Fund invests exclusively in short-term U.S. dollar denominated money market securities, including those issued by U.S. and foreign financial institutions, corporate issuers, the U.S. Government and its agencies and instrumentalities, municipalities, foreign governments, and multi-national organizations, such as the World Bank.

               Among the securities that the Money Market Fund may invest in are the following:

• Securities issued or guaranteed by the U.S. Government or its agencies, including Treasury Bills, notes, and securities issued by U.S. government agencies such as the Federal National Mortgage Association.

• Commercial paper issued or guaranteed by U.S. corporations and certain other entities that are rated in the two highest rating categories of a NRSRO.

• Repurchase agreements with certain parties.

• Certain obligations of large (more than $1 billion in total assets) U.S. banks and their subsidiaries (including, certain Canadian affiliates), including, but not limited to, bank notes, commercial paper, and certificates of deposit.

• Other short-term obligations issued by or guaranteed by U.S. corporations, state and municipal governments, or other entities.

• Securities backed by mortgages, consumer loans and other assets.

Principal Risks of Investing in the Fund

               Investors who purchase shares of the Fund are subject to various risks, and it is possible for you to lose money by investing in the Fund. Although the Fund seeks to preserve the value of your investment by maintaining a stable NAV of $1.00 per share, the Fund may not succeed and you may lose money by investing in the Fund. An investment in this Fund is not a deposit of any bank or other insured depository institution and is not insured or guaranteed by the Federal Deposit Insurance Corporation (“FDIC”) or another government agency. An investor in the Fund is subject to the following types of risks:

• Management Risk.    The assessment by the Fund’s investment adviser of the securities to be purchased or sold by the Fund may prove incorrect, resulting in losses or poor performance, even in a rising market.

• Interest Rate Risk and Call Risk.    The risk that the bonds the Fund holds may decline in value due to an increase in interest rates. All bonds, including those issued by the U.S. Government, are subject to interest rate risk. Bonds with longer maturities are affected more by interest rate movements than bonds with shorter maturities. Another risk associated with interest rate changes is call risk. Call risk is the risk that during periods of falling interest rates, a bond issuer will “call” or repay a higher yielding bond before the maturity date of the bond. Under these circumstances, the Fund may have to reinvest the proceeds in an investment that provides a lower yield than the called bond.

• Credit Risk.   The risk that a bond issuer fails to make principal or interest payments when due to the Fund, or that the credit quality of the issuer falls. Corporate bonds are subject to greater credit risk than U.S. Government bonds.

• Income Risk.   The risk that the income from the bonds the Fund holds will decline in value due to falling interest rates.

• Inflation Risk.    The risk that the value of the assets or income from an investment will be worth less in the future as inflation decreases the value of money.

               An investment in the Fund may be appropriate for you if you seek stability of principal, an investment for the cash portion of an asset allocation plan or are looking for an investment with a lower degree of risk. The Fund may not be suitable for you if you are seeking an investment that is likely to significantly outpace inflation, are investing for retirement or other longer term goals or are investing for growth or maximum current income.

Investment Results

               The following bar chart and table illustrate certain risks of investing in the Fund by showing changes in the Fund’s performance from year to year. This information is intended to help you assess the variability of the Fund’s returns over the periods listed to a measure of market performance (and consequently, the potential returns and risks of an investment in the Fund).

               The Fund’s past performance doesn’t necessarily indicate how it will perform in the future.

Strategy [Heading]	rr_StrategyHeading	Principal Investment Strategies
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund attempts to remain as fully invested as practicable in a pool of stocks and other equity securities that comprise the Russell 2000 in a manner that is expected to approximate the performance of the benchmark index. Under normal operating conditions, the Fund seeks to invest at least 90% of its net assets in stocks that are represented in the Russell 2000 and will at all times invest a substantial portion of its total assets in such stocks.
Risk [Heading]	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	Investors who purchase shares of the Fund are subject to various risks, and it is possible for you to lose money by investing in the Fund. An investment in this Fund is not a deposit of any bank or other insured depository institution and is not insured or guaranteed by the FDIC or another government agency. An investor in the Fund is subject to the following types of risks: Market Risk.    Stock prices may fluctuate widely over short or even extended periods in response to company, market, or economic news. Stock markets also tend to move in cycles, with periods of rising stock prices and periods of falling stock prices. Management Risk.    The assessment by the Fund’s investment adviser or sub-adviser of the securities to be purchased or sold by the Fund may prove incorrect, resulting in losses or poor performance, even in a rising market. Smaller Company Size Risk.    The securities of small capitalization companies are often more difficult to value or dispose of, more difficult to obtain information about, and more volatile than stocks of larger, more established companies. In addition, the markets for the Fund’s investments may not be actively traded, which increases the risk that the Fund’s investment adviser or sub-adviser may have difficulty selling securities the Fund holds. Indexing Risk.    This Fund attempts to match the performance of a securities market index, but there is no guarantee that this Fund will succeed in its attempt to match such performance. Security Selection Risk.    Because securities market indices are developed by persons unrelated to the Fund, the Manager or to the Fund’s sub-adviser, the Fund may hold stocks in companies that present risks that the Manager or the Fund’s sub-adviser researching individual stocks might avoid.                An investment in the Fund may be appropriate for you if you intend to maintain your investment for many years and through multiple stock market cycles. Because of stock market volatility, the Fund may not be a suitable investment if you have a short-term investment horizon or if you are unwilling to accept fluctuations in share price, including significant declines over a given period.

Unlike an investment in the Small Cap Equity Index Fund, returns of the Russell 2000 do not reflect expenses of investing.

Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund seeks to achieve investment performance that is similar to the S&P 500 Index (the Fund’s target benchmark). The S&P 500 Index is a widely used measure of large U.S. company stock performance. Standard & Poor’s (“S&P”) selects stocks for the S&P 500 Index based upon the following factors: market value industry group classification (so that the S&P 500 Index represents a broad range of industry segments within the U.S. economy) trading activity, to ensure ample liquidity and efficient share pricing fundamental analysis, to ensure that companies in the S&P 500 Index are stable                 The Fund pursues its investment objective by: investing in substantially all of the securities that make up the S&P 500 Index investing in these securities in proportions that match, approximately, the weightings of the S&P 500 Index                 Under normal operating conditions, the Fund seeks to invest at least 90% of its total assets in stocks that are represented in the S&P 500 Index.                 BlackRock Fund Advisors (“BFA”), the sub-adviser to the Fund, may sell securities to reflect security changes within the index or to balance the portfolio to the index. Securities may also be sold based upon tax considerations, liquidity needs or other portfolio management considerations.

Stock markets also tend to move in cycles, with periods of rising stock prices and periods of falling stock prices. Management Risk.    The assessment by the Fund’s investment adviser or sub-adviser of the securities to be purchased or sold by the Fund may prove incorrect, resulting in losses or poor performance, even in a rising market. Indexing Risk.     This Fund attempts to match the performance of a securities market index, but there is no guarantee that this Fund will succeed in its attempt to match such performance. Security Selection Risk.    Because securities market indices are developed by persons unrelated to the Fund, State Farm Investment Management Corp. (“SFIMC” or the “Manager”) or to the Fund’s sub-adviser, the Fund may hold stocks in companies that present risks that the Manager or the Fund’s sub-adviser researching individual stocks might avoid.                 An investment in the Fund may be appropriate for you if you intend to maintain your investment for many years and through multiple stock market cycles. Because of stock market volatility, the Fund may not be a suitable investment if you have a short-term investment horizon or if you are unwilling to accept fluctuations in share price, including significant declines over a given period.

State Farm Small Cap Equity Index Fund

SMALL CAP EQUITY INDEX FUND

               Investment Objective:

               The Small Cap Equity Index Fund (the “Fund”) seeks to match performance of the Russell 2000^® Small Stock Index (the “Russell 2000’) by investing in some of the stocks found in the Russell 2000.

What are the costs of investing in the Fund?

               This table describes the fees and expenses you may pay if you buy and hold shares of the Fund.

Annual Fund Operating Expenses
(expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses	State Farm Small Cap Equity Index Fund
Management Fees	0.40%
Distribution and Service (12b-1) Fees	none
Other Expenses	0.11%
Acquired Fund Fees and Expenses	0.08%
Total Annual Fund Operating Expenses	0.59%

               Expense Example

               This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds.

               The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example (USD $)	1 Year	3 Years	5 Years	10 Years
State Farm Small Cap Equity Index Fund	60	189	329	738

               The example does not reflect additional charges and expenses that are described in the prospectuses for the variable deferred annuity and variable universal life insurance policies issued by State Farm Life Insurance Company and State Farm Life and Accident Assurance Company. If those charges and expenses were included, the expenses would be higher.

Portfolio Turnover

               The Fund pays transaction costs, such as commissions, when it buys and sells securities (or turns over its portfolio). A higher portfolio turnover rate may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 14% of the average value of its portfolio.

Principal Investment Strategies

               The Fund attempts to remain as fully invested as practicable in a pool of stocks and other equity securities that comprise the Russell 2000 in a manner that is expected to approximate the performance of the benchmark index. Under normal operating conditions, the Fund seeks to invest at least 90% of its net assets in stocks that are represented in the Russell 2000 and will at all times invest a substantial portion of its total assets in such stocks.

Principal Risks of Investing in the Fund

               Investors who purchase shares of the Fund are subject to various risks, and it is possible for you to lose money by investing in the Fund. An investment in this Fund is not a deposit of any bank or other insured depository institution and is not insured or guaranteed by the FDIC or another government agency. An investor in the Fund is subject to the following types of risks:

• Market Risk.    Stock prices may fluctuate widely over short or even extended periods in response to company, market, or economic news. Stock markets also tend to move in cycles, with periods of rising stock prices and periods of falling stock prices.

• Management Risk.    The assessment by the Fund’s investment adviser or sub-adviser of the securities to be purchased or sold by the Fund may prove incorrect, resulting in losses or poor performance, even in a rising market.

• Smaller Company Size Risk.    The securities of small capitalization companies are often more difficult to value or dispose of, more difficult to obtain information about, and more volatile than stocks of larger, more established companies. In addition, the markets for the Fund’s investments may not be actively traded, which increases the risk that the Fund’s investment adviser or sub-adviser may have difficulty selling securities the Fund holds.

• Indexing Risk.    This Fund attempts to match the performance of a securities market index, but there is no guarantee that this Fund will succeed in its attempt to match such performance.

• Security Selection Risk.    Because securities market indices are developed by persons unrelated to the Fund, the Manager or to the Fund’s sub-adviser, the Fund may hold stocks in companies that present risks that the Manager or the Fund’s sub-adviser researching individual stocks might avoid.

               An investment in the Fund may be appropriate for you if you intend to maintain your investment for many years and through multiple stock market cycles. Because of stock market volatility, the Fund may not be a suitable investment if you have a short-term investment horizon or if you are unwilling to accept fluctuations in share price, including significant declines over a given period.

Investment Results

               The following bar chart and table illustrate certain risks of investing in the Fund by showing changes in the Fund’s performance from year to year. This information is intended to help you assess the variability of the Fund’s returns over the periods listed to a measure of market performance (and consequently, the potential returns and risks of an investment in the Fund).

               The Fund’s past performance doesn’t necessarily indicate how it will perform in the future.

Annual Total Returns For Calendar Years

               The Fund’s best and worst quarters during the periods in the bar chart were:

Best quarter: 22.85%,
               during the second quarter of 2003.

Worst quarter: -26.13%,
               during the fourth quarter of 2008.

               The following table shows the Average Annual Total Returns on an investment in the Fund compared to changes in the Russell 2000 for the 1, 5 and 10-year periods ended 12/31/2012. The Russell 2000^® Small Stock Index tracks the common stock performance of the 2,000 smallest U.S. companies in the Russell 3000^® Index, which represents approximately 10% of the total capitalization of the Russell 3000^® Index. Unlike an investment in the Small Cap Equity Index Fund, returns of the Russell 2000 do not reflect expenses of investing.

Average Annual Total Returns
(for the periods ended December 31, 2012)

Average Annual Total Returns	1 Year	5 Year	10 Year
State Farm Small Cap Equity Index Fund	15.90%	3.07%	9.16%

State Farm Large Cap Equity Fund

LARGE CAP EQUITY FUND

               Investment Objective:

               The Large Cap Equity Fund (or the “Fund”) seeks long-term growth of capital.

What are the costs of investing in the Fund?

               This table describes the fees and expenses you may pay if you buy and hold shares of the Fund.

Annual Fund Operating Expenses
(expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses	State Farm Large Cap Equity Fund
Management Fees	0.60%
Distribution and Service (12b-1) Fees	none
Other Expenses	0.15%
Acquired Fund Fees and Expenses	none
Total Annual Fund Operating Expenses	0.75%

               Expense Example

               This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds.

               The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example (USD $)	1 Year	3 Years	5 Years	10 Years
State Farm Large Cap Equity Fund	77	240	417	930

               The example does not reflect additional charges and expenses that are described in the prospectuses for the variable deferred annuity and variable universal life insurance policies issued by State Farm Life Insurance Company and State Farm Life and Accident Assurance Company. If those charges and expenses were included, the expenses would be higher.

Portfolio Turnover

               The Fund pays transaction costs, such as commissions, when it buys and sells securities (or turns over its portfolio). A higher portfolio turnover rate may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 58% of the average value of its portfolio.

Principal Investment Strategies

               Two different investment sub-advisers, Bridgeway Capital Management, Inc. (“Bridgeway”) and Westwood Management Corp. (“Westwood”), select investments for the Large Cap Equity Fund. Bridgeway and Westwood each manage approximately one-half of the Large Cap Equity Fund’s portfolio. State Farm Investment Management Corp. (the “Manager” or “SFIM”) monitors the performance of the sub-advisers and the allocation of the portfolio between the sub-advisers. The principal investment strategies employed by the two sub-advisers for their respective portions of the portfolio are discussed separately below.

Bridgeway

               Bridgeway primarily invests its portion of the Large Cap Equity Fund in a diversified portfolio of large growth stocks. Bridgeway defines “large stocks” as those whose market capitalization (stock market worth) falls within the range of the Russell 1000 Index, an unmanaged, market value weighted index, which measures performance of approximately 1,000 of the largest companies in the market with dividends reinvested. The Russell 1000 Index is reconstituted from time to time. The market capitalization of companies in which Bridgeway may invest may vary with market conditions. Growth stocks are those that Bridgeway believes have above average prospects for economic growth. Bridgeway selects stocks within the large-cap growth category for the Large Cap Equity Fund using a statistically driven approach. At least 80% of Bridgeway’s portion of the Large Cap Equity Fund’s net assets (plus borrowings for investment purposes) are invested in stocks from among those in the large-cap growth category at the time of purchase. However, Bridgeway will not necessarily sell a stock if it “migrates” to a different category after purchase.

Westwood

               Under normal market conditions, Westwood invests at least 80% of its portion of the Large Cap Equity Fund (which includes, for purposes of this test, the amount of any borrowings for investment purposes) primarily in common stocks of large capitalization companies, including foreign companies. Westwood invests in a portfolio of seasoned companies utilizing a value style of investing in which it chooses those stocks that Westwood believes have earnings prospects that are currently undervalued by the market relative to some financial measure of worth, such as the ratio of price to earnings, price to sales or price to cash flow. Westwood defines large capitalization companies as those companies with market capitalizations greater than $5 billion at the time of purchase, while seasoned companies generally have been operating for at least three years.

               In selecting securities, Westwood maintains a list of approved securities of issuers which it believes have proven records and potential for above-average earnings growth. Westwood considers purchasing a security on such list if Westwood’s forecast for growth rates and earnings for that issuer exceeds Wall Street expectations. Other key metrics for evaluating the risk/return profile of an investment include an improving return on equity, a declining debt to equity ratio and, in the case of common equities, positive earnings surprises without a corresponding increase in Wall Street estimates. Westwood has disciplines in place that serve as sell signals, such as a security reaching a pre-determined price target, and/or a fundamental change that negatively impacts the outlook and original investment thesis. The investment team will also review a stock if the price of the stock declines 15% or more in the first 45 days held. The risk characteristics of Westwood’s portion of the Large Cap Equity Fund, such as beta (a measure of volatility), are generally expected to be less than those of the S&P 500, the Fund’s benchmark.

               Both Bridgeway and Westwood may sell individual securities for several reasons including: price target of the security has been achieved, fundamental deterioration of company prospects, or better alternatives exist. Securities may also be sold based upon tax considerations, liquidity needs or other portfolio management considerations.

Principal Risks of Investing in the Fund

               Investors who purchase shares of the Large Cap Equity Fund are subject to various risks, and it is possible for you to lose money by investing in the Fund. An investment in this Fund is not a deposit of any bank or other insured depository institution and is not insured or guaranteed by the Federal Deposit Insurance Corporation (the “FDIC”) or another government agency. An investor in the Fund is subject to the following types of risks:

• Market Risk.    Stock prices may fluctuate widely over short or even extended periods in response to company, market, or economic news. Stock markets also tend to move in cycles, with periods of rising stock prices and periods of falling stock prices.

• Foreign Investing Risk.    Investing in foreign securities involves higher trading and custody costs than investing in U.S. companies. Accounting, legal and reporting practices are different than in the U.S. and regulation is often less stringent. Potential political or economic instability presents risks, as does the fluctuation in currency exchange rates, as well as the possible imposition of exchange control regulation or currency restrictions that could prevent the conversion of local currencies into U.S. dollars. Some foreign markets are considered to be emerging market countries. Investments in these countries subject the Fund to a greater risk of loss than investments in a developed country. This is due to, among other things, greater market volatility, lower trading volume, political and economic instability, greater risk of market shut down and more governmental limitations on foreign investment policy than those typically found in a developed market.

• Management Risk.    The assessment by the Fund’s investment adviser or sub-adviser of the securities to be purchased or sold by the Fund may prove incorrect, resulting in losses or poor performance, even in a rising market.

              An investment in the Fund may be appropriate for you if you intend to maintain your investment for many years and through multiple stock market cycles. Because of stock market volatility, the Fund may not be a suitable investment if you have a short-term investment horizon or if you are unwilling to accept fluctuations in share price, including significant declines over a given period.

Investment Results

              The following bar chart and table illustrate certain risks of investing in the Fund by showing changes in the Fund’s performance from year to year. This information is intended to help you assess the variability of the Fund’s returns over the periods listed to a measure of market performance (and consequently, the potential returns and risks of an investment in the Fund).

              The Fund’s past performance doesn’t necessarily indicate how it will perform in the future.

Strategy [Heading]	rr_StrategyHeading	Principal Investment Strategies
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Bond Fund invests primarily in investment grade bonds issued by U.S. companies, U.S. government and agency obligations, and mortgage backed securities. Under normal circumstances, the Bond Fund invests at least 80% of its net assets plus any borrowings in investment grade bonds or in bonds that are not rated, but that State Farm Investment Management Corp. (“SFIMC” or the “Manager”) has determined to be of comparable quality. A bond is investment grade if Moody’s Investors Service, Inc. (“Moody’s”) or S&P has rated the bond in one of their respective four highest rating categories. Non-investment grade bonds are commonly referred to as “junk bonds.” The Bond Fund may invest in any of the following instruments:                Corporate Debt Securities: investment grade securities issued by corporations and to a limited extent (up to 20% of its assets), in lower rated securities U.S. Government Debt Securities: securities issued or guaranteed by the U.S. Government or its agencies or instrumentalities Foreign Government Debt Securities: investment grade securities issued or guaranteed by a foreign government or its agencies or instrumentalities, payable in U.S. dollars Asset Backed and Mortgage Backed Securities: investment grade securities backed by mortgages, consumer loans and other assets Other Issuer Debt Securities: the Fund may invest up to 20% of its assets in non-investment grade debt securities and preferred stocks that are convertible into common stocks as well as nonconvertible preferred stocks or securities.                The Manager may sell individual securities for several reasons including: price target of the security has been achieved, fundamental deterioration of company prospects, or better alternatives exist. Securities may also be sold based upon tax considerations, liquidity needs or other portfolio management considerations.
Risk [Heading]	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	Investors who purchase shares of the Fund are subject to various risks, and it is possible for you to lose money by investing in the Fund. An investment in this Fund is not a deposit of any bank or other insured depository institution and is not insured or guaranteed by the FDIC or another government agency. An investor in the Fund is subject to the following types of risks: Management Risk.    The assessment by the Fund’s investment adviser of the securities to be purchased or sold by the Fund may prove incorrect, resulting in losses or poor performance, even in a rising market. Interest Rate Risk and Call Risk.    The risk that the bonds the Fund holds may decline in value due to an increase in interest rates. All bonds, including those issued by the U.S. Government, are subject to interest rate risk. Bonds with longer maturities are affected more by interest rate movements than bonds with shorter maturities. Another risk associated with interest rate changes is call risk. Call risk is the risk that during periods of falling interest rates, a bond issuer will “call” or repay a higher yielding bond before the maturity date of the bond. Under these circumstances, the Fund may have to reinvest the proceeds in an investment that provides a lower yield than the called bond. Prepayment and Extension Risk.    The risk that homeowners or consumers may alter the pace of repayment on their mortgage or consumer loans, which may affect the yield of mortgage-or asset-backed securities that are backed by such loans. Credit Risk.    The risk that a bond issuer fails to make principal or interest payments when due to the Fund, or that the credit quality of the issuer falls. Corporate bonds are subject to greater credit risk than U.S. Government bonds. High Yield, High Risk Securities.    Bonds that are in low or below investment-grade categories, or are unrated at the time of purchase (sometimes referred to as “junk bonds” or high yield securities) have a greater risk of default and are more volatile than higher-rated securities of similar maturity. The value of these securities is affected by overall economic conditions, interest rates, and the creditworthiness of the individual issuers. Additionally, these lower-rated or unrated bonds may be less liquid and more difficult to value than higher-rated securities. Liquidity Risk.    The investment adviser to the Fund may have difficulty selling securities the Fund holds at the time it would like to sell, and at the value the Fund has placed on those securities. Income Risk.    The risk that the income from the bonds the Fund holds will decline in value due to falling interest rates.                You may want to invest in the Fund if you are seeking higher potential returns than money market funds and are willing to accept the price volatility of bonds with longer maturities, want to diversify your investments, are seeking an income mutual fund for an asset allocation program or are retired or nearing retirement. You may not want to invest in the Fund if you are investing for maximum return over a long time horizon, want the greater growth potential of an investment in equity securities or require stability of your principal.

State Farm International Equity Fund

INTERNATIONAL EQUITY FUND

               Investment Objective:

               The International Equity Fund (the “Fund”) seeks long-term growth of capital.

What are the costs of investing in the Fund?

               This table describes the fees and expenses you may pay if you buy and hold shares of the Fund.

Annual Fund Operating Expenses
(expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses	State Farm International Equity Fund
Management Fees	0.80%
Distribution and Service (12b-1) Fees	none
Other Expenses	0.41%
Acquired Fund Fees and Expenses	none
Total Annual Fund Operating Expenses	1.21%

               Expense Example

               This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds.

               The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example (USD $)	1 Year	3 Years	5 Years	10 Years
State Farm International Equity Fund	123	384	665	1,466

               The example does not reflect additional charges and expenses that are described in the prospectuses for the variable deferred annuity and variable universal life insurance policies issued by State Farm Life Insurance Company and State Farm Life and Accident Assurance Company. If those charges and expenses were included, the expenses would be higher.

Portfolio Turnover

               The Fund pays transaction costs, such as commissions, when it buys and sells securities (or turns over its portfolio). A higher portfolio turnover rate may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 47% of the average value of its portfolio.

Principal Investment Strategies

               Two different investment sub-advisers, Marsico Capital Management, LLC (“Marsico”) and Northern Cross, LLC (“Northern Cross”), select investments for the International Equity Fund. Marsico and Northern Cross each manage approximately one-half of the International Equity Fund’s portfolio. State Farm Investment Management Corp. (the “Manager” or “SFIM”) monitors the performance of the sub-advisers and the split of the portfolio between the sub-advisers. The principal investment strategies employed by the two sub-advisers for their respective portions of the portfolio are discussed separately below.

Marsico

               Marsico invests its portion of the International Equity Fund primarily in common stock of foreign companies that it selects for their long-term growth potential. Marsico may invest its portion of the International Equity Fund in an unlimited number of companies of any size throughout the world, and normally invests in the securities of issuers that are economically tied to at least four different foreign countries. The Fund may invest in securities of companies economically tied to emerging markets. Some issuers of securities in the Fund’s portfolio may be based in or economically tied to the U.S. In selecting investments for the Fund, Marsico uses an approach that combines ‘top-down’ macro-economic analysis that focuses on broad financial and economic indicators with ‘bottom-up’ stock selection that initially focuses on individual stocks.

               Marsico may sell individual securities for several reasons including: price target of the security has been achieved, fundamental deterioration of company prospects, or better alternatives exist. Securities may also be sold based upon tax considerations, liquidity needs or other portfolio management considerations.

Northern Cross

               Northern Cross invests its portion of the International Equity Fund in securities issued by foreign companies in which it believes have the potential for long term margin expansion. Northern Cross primarily focuses on common stocks priced cheaply relative to some financial measure of worth, such as ratios of price to earnings, price to sales or price to cash flow. Under normal market conditions Northern Cross will invest its portion of the International Equity Fund in 60-80 companies with a diversified representation of sectors. In selecting securities for the International Equity Fund, Northern Cross gives careful consideration to currency, political stability and other effects of international investing.

               Northern Cross may sell individual securities for several reasons including: full valuation of the security has been achieved, fundamental deterioration of company prospects, or better alternatives exist. Securities may also be sold based upon tax considerations, liquidity needs or other portfolio management considerations.

Principal Risks of Investing in the Fund

               Investors who purchase shares of the Fund are subject to various risks, and it is possible for you to lose money by investing in the Fund. An investment in this Fund is not a deposit of any bank or other insured depository institution and is not insured or guaranteed by the FDIC or another government agency. An investor in the Fund is subject to the following types of risks:

• Market Risk.    Stock prices may fluctuate widely over short or even extended periods in response to company, market, or economic news. Stock markets also tend to move in cycles, with periods of rising stock prices and periods of falling stock prices.

• Foreign Investing Risk.    Investing in foreign securities involves higher trading and custody costs than investing in U.S. companies. Accounting, legal and reporting practices are different than in the U.S. and regulation is often less stringent. Potential political or economic instability presents risks, as does the fluctuation in currency exchange rates, as well as the possible imposition of exchange control regulation or currency restrictions that could prevent the conversion of local currencies into U.S. dollars. Some foreign markets are considered to be emerging market countries. Investments in these countries subject the Fund to a greater risk of loss than investments in a developed country. This is due to, among other things, greater market volatility, lower trading volume, political and economic instability, greater risk of market shut down and more governmental limitations on foreign investment policy than those typically found in a developed market.

• Management Risk.    The assessment by the Fund’s investment adviser or sub-adviser of the securities to be purchased or sold by the Fund may prove incorrect, resulting in losses or poor performance, even in a rising market.

               An investment in the Fund may be appropriate for you if you intend to maintain your investment for many years and through multiple stock market cycles. Because of stock market volatility, the Fund may not be a suitable investment if you have a short-term investment horizon or if you are unwilling to accept fluctuations in share price, including significant declines over a given period.

Investment Results

               The following bar chart and table illustrate certain risks of investing in the Fund by showing changes in the Fund’s performance from year to year. This information is intended to help you assess the variability of the Fund’s returns over the periods listed to a measure of market performance (and consequently, the potential returns and risks of an investment in the Fund). The inception date for the Fund is August 1, 2005.

               The Fund’s past performance doesn’t necessarily indicate how it will perform in the future.

Annual Total Returns For Calendar Years

               The Fund’s best and worst quarters during the periods in the bar chart were:

Best quarter: 25.61%,
               during the second quarter of 2009.

Worst quarter: -23.84%,
               during the fourth quarter of 2008.

               The following table shows the Average Annual Total Returns on an investment in the Fund compared to changes in the Morgan Stanley Capital International All Country World Index (ex-U.S.) (the “MSCI ACWI ex-U.S. Index”) for the 1-year, 5 year and since inception periods ended December 31, 2012. MSCI ACWI ex-U.S. Index is a free float adjusted market capitalization index that is designed to measure equity market performance in global developed and emerging markets, excluding the United States. As of December 31, 2012, the MSCI AWCI ex-U.S. Index consisted of 44 developed and emerging market country indices.

Average Annual Total Returns
(for the periods ended December 31, 2012)

Average Annual Total Returns	1 Year	5 Year	From Inception to 12/31/2012	Inception Date
State Farm International Equity Fund	19.19%	(3.40%)	3.39%	Aug. 01, 2005

State Farm International Equity Index Fund

INTERNATIONAL EQUITY INDEX FUND

               Investment Objective:

               The International Equity Index Fund (the “Fund”) seeks to match performance of the Morgan Stanley Capital International Europe, Australasia, and Far East Free Index^® (the “EAFE Free”) by investing in some of the stocks found in the EAFE Free.

What are the costs of investing in the Fund?

               This table describes the fees and expenses you may pay if you buy and hold shares of the Fund.

Annual Fund Operating Expenses
(expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses	State Farm International Equity Index Fund
Management Fees	0.55%
Distribution and Service (12b-1) Fees	none
Other Expenses	0.13%
Acquired Fund Fees and Expenses	none
Total Annual Fund Operating Expenses	0.68%

               Expense Example

               This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds.

                The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example (USD $)	1 Year	3 Years	5 Years	10 Years
State Farm International Equity Index Fund	69	218	379	847

               The example does not reflect additional charges and expenses that are described in the prospectuses for the variable deferred annuity and variable universal life insurance policies issued by State Farm Life Insurance Company and State Farm Life and Accident Assurance Company. If those charges and expenses were included, the expenses would be higher.

Portfolio Turnover

               The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 3% of the average value of its portfolio.

Principal Investment Strategies

               The Fund attempts to remain as fully invested as practicable in a pool of stocks and other equity securities that comprise the EAFE Free in a manner that is expected to approximate the performance of the benchmark index. Under normal operating conditions, the Fund seeks to invest at least 90% of its net assets in stocks that are represented in the EAFE Free and will at all times invest a substantial portion of its total assets in such stocks.

Principal Risks of Investing in the Fund

               Investors who purchase shares of the Fund are subject to various risks, and it is possible for you to lose money by investing in the Fund. An investment in this Fund is not a deposit of any bank or other insured depository institution and is not insured or guaranteed by the FDIC or another government agency. An investor in the Fund is subject to the following types of risks:

• Market Risk.    Stock prices may fluctuate widely over short or even extended periods in response to company, market, or economic news. Stock markets also tend to move in cycles, with periods of rising stock prices and periods of falling stock prices.

• Foreign Investing Risk.    Investing in foreign securities involves higher trading and custody costs than investing in U.S. companies. Accounting, legal and reporting practices are different than in the U.S. and regulation is often less stringent. Potential political or economic instability presents risks, as does the fluctuation in currency exchange rates, as well as the possible imposition of exchange control regulation or currency restrictions that could prevent the conversion of local currencies into U.S. dollars. Some foreign markets are considered to be emerging market countries. Investments in these countries subject the Fund to a greater risk of loss than investments in a developed country. This is due to, among other things, greater market volatility, lower trading volume, political and economic instability, greater risk of market shut down and more governmental limitations on foreign investment policy than those typically found in a developed market.

• Management Risk.    The assessment by the Fund’s investment adviser or sub-adviser of the securities to be purchased or sold by the Fund may prove incorrect, resulting in losses or poor performance, even in a rising market.

• Indexing Risk.    This Fund attempts to match the performance of a securities market index, but there is no guarantee that this Fund will succeed in its attempt to match such performance.

• Security Selection Risk.    Because securities market indices are developed by persons unrelated to the Fund, the Manager or to the Fund’s sub-adviser, the Fund may hold stocks in companies that present risks that the Manager or the Fund’s sub-adviser researching individual stocks might avoid.

               An investment in the Fund may be appropriate for you if you intend to maintain your investment for many years and through multiple stock market cycles. Because of stock market volatility, the Fund may not be a suitable investment if you have a short-term investment horizon or if you are unwilling to accept fluctuations in share price, including significant declines over a given period.

               The Fund’s best and worst quarters during the periods in the bar chart were:

Best quarter: 25.25%,
               during the second quarter of 2009.

Worst quarter: -20.17%,
               during the third quarter of 2011.

               The following table shows the Average Annual Total Returns on an investment in the Fund compared to changes in the EAFE^® Free for the 1, 5 and 10-year periods ended 12/31/2012. The EAFE^® Free Index currently measures the performance of stock markets in Europe, Australia, New Zealand, Hong Kong, Japan, and Singapore, and takes into account local market restrictions on share ownership by foreigners. The EAFE^® Free Index is meant to reflect actual opportunities for foreign investors in a local market. Unlike an investment in the International Equity Index Fund, returns of the EAFE^® Free Index do not reflect expenses of investing.
