DFA Short-Duration Inflation Protected Securities Portfolio

INVESTMENT OBJECTIVE

The investment objective of the DFA Short-Duration Inflation Protected Securities Portfolio (the “Short-Duration Inflation Protected Securities Portfolio” or the “Portfolio”) is to seek inflation protection and maximize total returns from the universe of eligible investments.

FEES AND EXPENSES OF THE PORTFOLIO

This table describes the fees and expenses you may pay if you buy and hold shares of the Short-Duration Inflation Protected Securities Portfolio.

Shareholder Fees (fees paid directly from your investment): None

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

	Management Fee	0.20%
	Other Expenses*	0.11%
	Acquired Fund Fees and Expenses**	0.21%
	Total Annual Fund Operating Expenses	0.52%
	Fee Waiver and/or Expense Reimbursement***	0.28%
	Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement	0.24%

* The Short-Duration Inflation Protected Securities Portfolio is a new portfolio, so the “Other Expenses” shown are based on anticipated fees and expenses for the first full fiscal year.

** Represents the amount of fees and expenses anticipated to be incurred by the Short-Duration Inflation Protected Securities Portfolio through its investments in other funds managed by the Advisor (the “Underlying Funds”) and other investment companies for the first full fiscal year.

*** Pursuant to a Fee Waiver and Expense Assumption Agreement for the Portfolio, the Advisor has contractually agreed to waive up to the full amount of the Portfolio’s management fee of 0.20% to the extent necessary to offset the proportionate share of the management fees paid by the Portfolio through its investment in other funds managed by the Advisor (the “Underlying Funds”). In addition, under the Fee Waiver and Expense Assumption Agreement, the Advisor has also agreed to waive all or a portion of the management fee and to assume the ordinary operating expenses of a class of the Portfolio (including the expenses that the Portfolio bears as a shareholder of other funds managed by the Advisor but excluding the expenses that the Portfolio incurs indirectly through its investment in unaffiliated investment companies and excluding any applicable 12b-1 fees) (“Portfolio Expenses”) to the extent necessary to limit the Portfolio Expenses of a class of the Portfolio to 0.24% of the average net assets of a class of the Portfolio on an annualized basis (the “Expense Limitation Amount”). The Fee Waiver and Expense Assumption Agreement for the Portfolio will remain in effect through February 28, 2015, and may not be terminated by the Advisor prior to that date. At any time that the Portfolio’s annualized Portfolio Expenses are less than the Portfolio’s Expense Limitation Amount, described above, the Advisor retains the right to seek reimbursement for any fees previously waived and/or expenses previously assumed to the extent that such reimbursement will not cause the annualized Portfolio Expenses of a class of the Portfolio to exceed the Expense Limitation Amount. The Portfolio is not obligated to reimburse the Advisor for fees previously waived or expenses previously assumed by the Advisor more than thirty-six months before the date of such reimbursement.

Example

This Example is meant to help you compare the cost of investing in the Short-Duration Inflation Protected Securities Portfolio with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Portfolio 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 Portfolio’s operating expenses remain the same. The costs for the Short-Duration Inflation Protected Securities Portfolio reflect the net expenses of the Portfolio that result from the contractual

expense waiver in the first year only. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

l Year	3 Years
$25	$138

Portfolio Turnover

The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover may indicate higher transaction costs and may result in higher taxes when Portfolio shares are held in a taxable account. These costs, which are not reflected in Annual Fund Operating Expenses or in the Example, affect Portfolio’s performance. The Portfolio does not pay transaction costs when buying and selling share of other mutual funds (the “Underlying Funds”); however, the Underlying Funds pay transaction costs when buying and selling securities for their portfolios. Because Portfolio is new, information about portfolio turnover rate is not yet available.

PRINCIPAL INVESTMENT STRATEGIES

Dimensional Fund Advisors LP (the “Advisor”) believes that fixed income investing should involve a long-term view and a systematic focus on bond market risk and return, not on interest rate forecasting or market timing.

The Short-Duration Inflation Protected Securities Portfolio pursues its investment objective by investing directly or through other mutual funds managed by the Advisor in a combination of debt securities, including inflation-protected securities, and derivative instruments. At inception, the Portfolio will invest a substantial portion of its assets in the DFA Short-Term Extended Quality Portfolio, DFA Intermediate-Term Extended Quality Portfolio and DFA One-Year Fixed Income Portfolio (the “Underlying Funds”), but it is contemplated that the Portfolio will also purchase securities, including inflation-protected securities, and derivative instruments directly.

In constructing an investment portfolio, the Advisor identifies a broadly diversified universe of eligible securities with precisely defined maturity ranges and credit quality characteristics. The Advisor will then seek to purchase a broad and diverse portfolio of securities meeting these credit quality standards. In making these purchase decisions, if the anticipated maturity risk premium is greater for longer-term securities in the eligible maturity range, the Advisor will focus investment in that longer-term area; otherwise, the Portfolio will focus investment in the short-term range of the eligible maturity range. The Short-Duration Inflation Protected Securities Portfolio will maintain an average portfolio duration of three years or less. The fixed income securities in which the Short-Duration Inflation Protected Securities Portfolio directly or indirectly invests are considered investment grade at the time or purchase.

The Short-Duration Inflation Protected Securities Portfolio may invest directly or through its investment in the Underlying Funds in inflation protected securities, obligations issued or guaranteed by the U.S. and foreign governments, their agencies and instrumentalities, corporate debt obligations, bank obligations, commercial paper, repurchase agreements, obligations of other domestic and foreign issuers, securities of domestic or foreign issuers denominated in U.S. dollars but not trading in the United States, and obligations of supranational organizations.

The Short-Duration Inflation Protected Securities Portfolio may enter into swaps, such as inflation swaps, to seek inflation protection. The Portfolio and certain Underlying Funds also may enter into credit default swaps on issuers or indices to buy or sell credit protection to hedge its credit exposure; gain market or issuer exposure without owning the underlying securities; or increase the Portfolio’s total return. The Portfolio and certain Underlying Funds also may use derivatives, such as futures contracts and options on futures contracts, for non-hedging purposes as a substitute for direct investment or to allow the Portfolio or an Underlying Fund to remain fully invested while maintaining the liquidity required to pay redemptions. The Portfolio and certain Underlying Funds may use forward foreign currency contracts to attempt to protect against uncertainty in the level of future foreign currency rates, to hedge against fluctuations in currency exchange rates or to transfer balances from one currency to another.

The Short-Duration Inflation Protected Securities Portfolio and each Underlying Fund may concentrate its investments in obligations of U.S. and foreign banks and bank holding companies. The Portfolio and each Underlying Fund will concentrate its assets (invest more than 25% of its total assets) in obligations of U.S. and/or foreign banks and bank holding companies (“banking industry securities”) when the yield to maturity on eligible portfolio investments in banking

industry securities as a group generally exceeds the yield to maturity on all other eligible portfolio investments as a group generally for a period of five consecutive days when the New York Stock Exchange is open for trading. See the section entitled “Investments in the Banking Industry” below for additional information.

The Short-Duration Inflation Protected Securities Portfolio and the Underlying Funds may lend their portfolio securities to generate additional income.

A summary of the investment strategies and policies of the Underlying Funds in which the Short-Duration Inflation Protected Securities Portfolio may invest as of the date of this Prospectus is described in the Portfolio’s Prospectus in the section entitled “ADDITIONAL INFORMATION ON INVESTMENT OBJECTIVES AND POLICIES.”

PRINCIPAL RISKS

Fund of Funds Risk: The investment performance of the Short-Duration Inflation Protected Securities Portfolio is affected by the investment performance of the Underlying Funds in which the Portfolio invests. The ability of the Portfolio to achieve its investment objective depends on the ability of the Underlying Funds to meet their investment objectives and on the Advisor’s decisions regarding the allocation of the Portfolio’s assets among the Underlying Funds. The Portfolio may allocate assets to an Underlying Fund that underperforms other funds. There can be no assurance that the investment objective of the Portfolio or any Underlying Fund will be achieved. Through its investments in the Underlying Funds, the Portfolio is subject to the risks of the Underlying Funds’ investments. When the Portfolio invests in Underlying Funds, investors are exposed to a proportionate share of the expenses of those Underlying Funds in addition to the expenses of the Portfolio. The risks listed below for the Portfolio include both the risks associated with direct investment in securities by the Portfolio and indirect investment in securities through the Portfolio’s investment in the Underlying Funds.

Market Risk: Even a long-term investment approach cannot guarantee a profit. Economic, political, and issuer-specific events will cause the value of securities, and the Underlying Funds that own them, and, in turn, the Short-Duration Inflation Protected Securities Portfolio itself, to rise or fall. Because the value of your investment in the Portfolio will fluctuate, there is the risk that you will lose money.

Foreign Securities and Currencies Risk: Foreign securities prices may decline or fluctuate because of: (a) economic or political actions of foreign governments, and/or (b) less regulated or liquid securities markets. Investors holding these securities may also be exposed to foreign currency risk (the possibility that foreign currency will fluctuate in value against the U.S. dollar or that a foreign government will convert, or be forced to convert, its currency to another currency, changing its value against the U.S. dollar).

Foreign Government Debt Risk: The risk that: (a) the governmental entity that controls the repayment of government debt may not be willing or able to repay the principal and/or to pay the interest when it becomes due, due to factors such as political considerations, the relative size of the governmental entity’s debt position in relation to the economy, cash flow problems, insufficient foreign currency reserves, the failure to put in place economic reforms required by the International Monetary Fund or other multilateral agencies, and/or other national economic factors; (b) governments may default on their debt securities, which may require holders of such securities to participate in debt rescheduling; and (c) there is no legal or bankruptcy process by which defaulted government debt may be collected in whole or in part.

Interest Rate Risk: Fixed income securities are subject to interest rate risk because the prices of fixed income securities tend to move in the opposite direction of interest rates. When interest rates rise, fixed income security prices fall. When interest rates fall, fixed income security prices rise. In general, fixed income securities with longer maturities are more sensitive to these price changes.

Inflation-Protected Securities Interest Rate Risk: Inflation-protected securities may react differently from other fixed income securities to changes in interest rates. Because interest rates on inflation-protected securities are adjusted for inflation, the values of these securities are not materially affected by inflation expectations. Therefore, the value of inflation-protected securities are anticipated to change in response to changes in “real” interest rates, which represent nominal (stated) interest rates reduced by the expected impact of inflation. Generally, the value of an inflation-protected security will fall when real interest rates rise and will rise when real interest rates fall.

Credit Risk: Credit risk is the risk that the issuer of a security may be unable to make interest payments and/or repay principal when due. A downgrade to an issuer’s credit rating or a perceived change in an issuer’s financial strength may affect a security’s value, and thus, impact the Portfolio’s performance. Government agency obligations have different levels of credit support and, therefore, different degrees of credit risk. Securities issued by agencies and instrumentalities of the U.S. Government that are supported by the full faith and credit of the United States, such as the Federal Housing Administration and Ginnie Mae, present little credit risk. Other securities issued by agencies and instrumentalities sponsored by the U.S. Government, that are supported only by the issuer’s right to borrow from the U.S. Treasury, subject to certain limitations, and securities issued by agencies and instrumentalities sponsored by the U.S. Government that are sponsored by the credit of the issuing agencies, such as Freddie Mac and Fannie Mae, are subject to a greater degree of credit risk. U.S. government agency securities issued or guaranteed by the credit of the agency may still involve a risk of non-payment of principal and/or interest.

Risks of Investing for Inflation Protection: Because the interest and/or principal payments on an inflation-protected security are adjusted periodically for changes in inflation, the income distributed by the Portfolio may be irregular. Although the U.S. Treasury guarantees to pay at least the original face value of any inflation-protected securities the Treasury issues, other issuers may not offer the same guarantee. Also, inflation-protected securities, including those issued by the U.S. Treasury, are not protected against deflation. As a result, in a period of deflation, the inflation-protected securities held by the Portfolio may not pay any income and the Portfolio may suffer a loss during such periods. While inflation-protected securities are expected to be protected from long-term inflationary trends, short-term increases in inflation may lead to a decline in the Portfolio’s value. If interest rates rise due to reasons other than inflation, the Portfolio’s investment in these securities may not be protected to the extent that the increase is not reflected in the securities’ inflation measures. In addition, positive adjustments to principal generally will result in taxable income to the Portfolio at the time of such adjustments (which generally would be distributed by the Portfolio as part of its taxable dividends), even though the principal amount is not paid until maturity. The current market value of inflation-protected securities is not guaranteed and will fluctuate.

Income Risk: Income risk is the risk that falling interest rates will cause the Portfolio’s income to decline.

Risks of Banking Concentration: Focus on the banking industry would link the performance of the Portfolio to changes in the performance of the banking industry generally. Banks are very sensitive to changes in money market and general economic conditions. The profitability of the banking industry is dependent upon banks being able to obtain funds at reasonable costs and upon liquidity in the capital and credit markets to finance their lending operations. Adverse general economic conditions can cause financial difficulties for a bank’s borrowers and the borrowers’ failure to repay their loans can adversely affect the bank’s financial situation. Banks are subject to extensive regulation and decisions by regulators may limit the loans banks make and the interest rates and fees they charge, which could reduce bank profitability.

Derivatives Risk: Derivatives are instruments, such as swaps, futures and foreign exchange forward contracts, whose value is derived from that of other assets, rates or indices. Derivatives can be used for hedging (attempting to reduce risk by offsetting one investment position with another) or non-hedging purposes. The use of derivatives for non-hedging purposes may be considered more speculative than other types of investments. When the Portfolio or the Underlying Funds use derivatives, the Short-Duration Inflation Protected Securities Portfolio will be exposed to the risks of those derivatives. Derivative instruments are subject to a number of risks including counterparty, liquidity, interest rate, market, credit and management risks, and the risk of improper valuation. Changes in the value of a derivative may not correlate perfectly with the underlying asset, rate or index, and the Portfolio or an Underlying Fund could lose more than the principal amount invested. Additional risks are associated with the use of credit default swaps including counterparty and credit risk (the risk that the other party to a swap agreement will not fulfill its contractual obligations, whether because of bankruptcy or other default) and liquidity risk (the possible lack of a secondary market for the swap agreement).

Securities Lending Risk: Securities lending involves the risk that the borrower may fail to return the securities in a timely manner or at all. As a result, an Underlying Fund may lose money and there may be a delay in recovering the loaned securities. An Underlying Fund could also lose money if it does not recover the securities and/or the value of the collateral falls, including the value of investments made with cash collateral. Securities lending also may have certain adverse tax consequences. To the extent that the Portfolio holds securities directly and lends those securities, it will be also subject to the foregoing risks with respect to its loaned securities.

ADDITIONAL INFORMATION ON INVESTMENT OBJECTIVES AND POLICIES

DFA Investment Dimensions Group Inc. (the “Fund”) offers a variety of investment portfolios. Each of the investment company’s portfolios has its own investment objective and is the equivalent of a separate mutual fund. Institutional Class shares of the Short-Duration Inflation Protected Securities Portfolio are offered in this Prospectus. The Short-Duration Inflation Protected Securities Portfolio is designed for long-term investors.

The Short-Duration Inflation Protected Securities Portfolio seeks its investment objective by investing directly or through other mutual funds managed by the Advisor in a combination of debt securities, including inflation-protected securities, and derivative instruments. At inception, the Portfolio will invest a substantial portion of its assets in the DFA Short-Term Extended Quality Portfolio, DFA Intermediate-Term Extended Quality Portfolio and DFA One-Year Fixed Income Portfolio (the “Underlying Funds”), but it is contemplated that the Portfolio will also purchase securities, including inflation protected securities, and derivative instruments directly.

Inflation-protected securities (also known as inflation-indexed securities) are securities whose principal and/or interest payments are adjusted for inflation, unlike conventional debt securities that make fixed principal and interest payments. Inflation-protected securities include Treasury Inflation-Protected Securities (“TIPS”), which are securities issued by the U.S. Treasury. The principal value of TIPS is adjusted for inflation (payable at maturity) and the semi-annual interest payments by TIPS equal a fixed percentage of the inflation-adjusted principal amount. These inflation adjustments are based upon the Consumer Price Index for Urban Consumers (CPI-U). The original principal value of TIPS is guaranteed, even during periods of deflation. At maturity, TIPS are redeemed at the greater of their inflation-adjusted principal or par amount at original issue. Other types of inflation-protected securities may use other methods to adjust for inflation and other measures of inflation. In addition, inflation-protected securities issued by entities other than the U.S. Treasury may not provide a guarantee of principal value at maturity.

The Short-Duration Inflation Protected Securities Portfolio will be managed with a view to capturing credit risk premiums and maturity risk premiums. The term “credit risk premium” means the expected incremental return on investment for holding obligations considered to have greater credit risk than direct obligations of the U.S. Treasury, and “maturity risk premium” means the expected incremental return on investment for holding securities having longer-term maturities as compared to shorter-term maturities. In making investment decisions for the Portfolio, the Advisor will increase or decrease exposure to intermediate-term securities depending on the expected maturity risk premium and also increase or decrease exposure to non-government securities depending on the expected credit risk premium.

The Short-Duration Inflation Protected Securities Portfolio will maintain an average portfolio duration of three years or less and invest directly or indirectly in securities considered to be investment grade at the time of purchase. Duration is a measure of the expected life of a fixed income security that is used to determine the sensitivity of a security’s price to changes in interest rates. The longer a security’s duration, the more sensitive it will be to changes in interest rates. Securities are considered investment grade if the issuer has received a rating of BBB- or better by Standard & Poor’s Rating Group (“S&P”) or Fitch Ratings Ltd. (“Fitch”) or Baa3 or better by Moody’s Investor’s Service, Inc. (“Moody’s”).

The Short-Duration Inflation Protected Securities Portfolio may enter into swaps, such as inflation swaps, to seek inflation protection. The Portfolio also may enter into credit default swaps on issuers or indices to buy or sell credit protection to hedge its credit exposure; gain market or issuer exposure without owning the underlying securities; or increase the Portfolio’s total return. The Portfolio also may use derivatives, such as futures contracts and options on futures contracts, for non-hedging purposes as a substitute for direct investment or to allow the Portfolio to remain fully invested while maintaining the liquidity required to pay redemptions. The Portfolio may use forward foreign currency contracts to attempt to protect against uncertainty in the level of future foreign currency rates, to hedge against fluctuations in currency exchange rates or to transfer balances from one currency to another.

Investment Strategies of the Underlying Funds

The following is a summary of the investment strategies and policies of Underlying Funds in which the Short-Duration Inflation Protected Securities Portfolio may invest as of the date of this Prospectus. In addition to, or in place of, investments in its Underlying Funds, the Short-Duration Inflation Protected Securities Portfolio also is permitted to invest directly in the same types of securities that are described below as eligible investments for its Underlying Funds.

DFA Short-Term Extended Quality Portfolio—The DFA Short-Term Extended Quality Portfolio (the “Short-Term Extended Quality Portfolio”) seeks to maximize total returns from a universe of U.S. and foreign corporate debt securities with an investment grade credit rating. The Short-Term Extended Quality Portfolio invests with an emphasis on a universe of U.S. and foreign corporate debt securities the Advisor considers to be of extended quality as they are rated in the lower half of the investment grade spectrum (i.e., rated BBB- to A+ by S&P or Fitch or Baa3 to A1 Moody’s). The Portfolio will not emphasize investments in the lower half of the investment grade spectrum, however, when the Advisor believes the credit risk premium does not warrant the investment. The Portfolio will also invest in higher-rated corporate debt securities, obligations issued or guaranteed by the U.S. and foreign governments, their agencies and instrumentalities, bank obligations, commercial paper, repurchase agreements, obligations of other domestic and foreign issuers having investment grade ratings, securities of domestic or foreign issuers denominated in U.S. dollars but not trading in the United States, and obligations of supranational organizations. At the present time, the Advisor expects that most investments will be made in the obligations of issuers that are located in developed countries. However, in the future, the Advisor anticipates investing in issuers located in other countries as well.

The Short-Term Extended Quality Portfolio primarily invests in securities that mature within five years from the date of settlement and maintains an average portfolio maturity and average portfolio duration of three years or less. As a non-fundamental policy, under normal circumstances, the Portfolio will invest at least 80% of its net assets in fixed income securities considered to be investment grade quality.

The Short-Term Extended Quality Portfolio’s investments may include foreign securities denominated in foreign currencies. The Portfolio intends to hedge any foreign currency exposure to attempt to protect against uncertainty in the level of future foreign currency rates. The Portfolio may enter into foreign forward currency contracts to hedge against fluctuations in currency exchange rates or to transfer balances from one currency to another. The Portfolio also may enter into credit default swaps on issuers or indices to buy or sell credit protection to hedge its credit exposure; gain market or issuer exposure without owning the underlying securities; or increase the Portfolio’s total return. The Portfolio also may use derivatives, such as futures contracts and options on futures contracts, for non-hedging purposes as a substitute for direct investment or to allow the Portfolio to remain fully invested while maintaining the liquidity required to pay redemptions.

The Short-Term Extended Quality Portfolio may concentrate its investments in obligations of U.S. and foreign banks and bank holding companies. The Portfolio will concentrate its assets (invest more than 25% of its total assets) in obligations of U.S. and/or foreign banks and bank holding companies (“banking industry securities”) when the yield to maturity on eligible portfolio investments in banking industry securities as a group generally exceeds the yield to maturity on all other eligible portfolio investments as a group generally for a period of five consecutive days when the New York Stock Exchange is open for trading. See the section entitled “Investments in the Banking Industry” below for additional information.

DFA Intermediate-Term Extended Quality Portfolio—The DFA Intermediate-Term Extended Quality Portfolio (the “Intermediate-Term Extended Quality Portfolio”) seeks to maximize total returns from a universe of U.S. and foreign corporate debt securities with an investment grade credit rating. The Intermediate-Term Extended Quality Portfolio invests with an emphasis on a universe of U.S. and foreign corporate debt securities the Advisor considers to be of extended quality as they are rated in the lower half of the investment grade spectrum (i.e., rated BBB- to A+ by S&P or Fitch or Baa3 to A1 Moody’s). The Portfolio will not emphasize investments in the lower half of the investment grade spectrum, however, when the Advisor believes the credit risk premium does not warrant the investment. The Portfolio will also invest in higher-rated corporate debt securities, obligations issued or guaranteed by the U.S. and foreign governments, their agencies and instrumentalities, bank obligations, commercial paper, repurchase agreements, obligations of other domestic and foreign issuers having investment grade ratings, securities of domestic or foreign issuers denominated in U.S. dollars but not trading in the United States, and obligations of supranational organizations. At the present time, the Advisor expects that most investments will be made in the obligations of issuers that are located in developed countries. However, in the future, the Advisor anticipates investing in issuers located in other countries as well.

The Intermediate-Term Extended Quality Portfolio primarily invests in securities that mature within three to fifteen years from the date of settlement and maintains an average portfolio maturity and average portfolio duration of between three and ten years. As a non-fundamental policy, under normal circumstances, the Portfolio will invest at least 80% of its net assets in fixed income securities considered to be investment grade quality.

The Intermediate-Term Extended Quality Portfolio’s investments may include foreign securities denominated in foreign currencies. The Portfolio intends to hedge any foreign currency exposure to attempt to protect against uncertainty in the level of future foreign currency rates. The Portfolio may enter into foreign forward currency contracts to hedge against fluctuations in currency exchange rates or to transfer balances from one currency to another. The Portfolio also may enter into credit default swaps on issuers or indices to buy or sell credit protection to hedge its credit exposure; gain market or issuer exposure without owning the underlying securities; or increase the Portfolio’s total return. The Portfolio also may use derivatives, such as futures contracts and options on futures contracts, for non-hedging purposes as a substitute for direct investment or to allow the Portfolio to remain fully invested while maintaining the liquidity required to pay redemptions.

The Intermediate-Term Extended Quality Portfolio may concentrate its investments in obligations of U.S. and foreign banks and bank holding companies. The Portfolio will concentrate its assets (invest more than 25% of its total assets) in obligations of U.S. and/or foreign banks and bank holding companies (“banking industry securities”) when the yield to maturity on eligible portfolio investments in banking industry securities as a group generally exceeds the yield to maturity on all other eligible portfolio investments as a group generally for a period of five consecutive days when the New York Stock Exchange is open for trading. See the section entitled “Investments in the Banking Industry” below for additional information.

DFA One-Year Fixed Income Portfolio—The DFA One Year Fixed Income Portfolio (the “One-Year Portfolio”) seeks to achieve a stable real return in excess of the rate of inflation with a minimum of risk by generally investing in a universe of high quality fixed income securities that typically mature in one year or less. The Portfolio may, however, take a large position in securities maturing within two years of the date of settlement when higher yields are available. The One-Year Portfolio invests in U.S. government obligations, U.S. government agency obligations, dollar-denominated obligations of foreign issuers issued in the U.S., foreign government and agency obligations, bank obligations, including U.S. subsidiaries and branches of foreign banks, corporate obligations, commercial paper, repurchase agreements and obligations of supranational organizations. As a non-fundamental policy, under normal circumstances, the Portfolio will invest at least 80% of its net assets in fixed income securities and maintain a weighted average portfolio maturity that will not exceed one year. The Portfolio principally invests in certificates of deposit, commercial paper, bankers’ acceptances, notes and bonds.

The One-Year Portfolio may concentrate its investments in obligations of U.S. and foreign banks and bank holding companies. The Portfolio will concentrate its assets (invest more than 25% of its total assets) in obligations of U.S. and/or foreign banks and bank holding companies (“banking industry securities”) when the yield to maturity on eligible portfolio investments in banking industry securities as a group generally exceeds the yield to maturity on all other eligible portfolio investments as a group generally for a period of five consecutive days when the New York Stock Exchange is open for trading. See the section entitled “Investments in the Banking Industry” below for additional information.

Investments in the Banking Industry. The Portfolio and each Underlying Fund will invest more than 25% of their total respective assets in obligations of U.S. and foreign banks and bank holding companies (“banking industry securities”) when the yield to maturity on eligible portfolio investments in banking industry securities as a group generally exceeds the yield to maturity on all other eligible portfolio investments as a group generally for a period of five consecutive days when the NYSE is open for trading. For purposes of this policy, the Advisor considers eligible portfolio investments to be those securities that are on the Advisor’s then current buy list that are available for purchase. This policy can only be changed by a vote of shareholders. When investment in such obligations exceeds 25% of the total net assets of a Portfolio or Underlying Fund, such Portfolio or Underlying Fund will be considered to be concentrating its investments in the banking industry. Once a Portfolio or Underlying Fund concentrates its investments in the banking industry, the Portfolio or Underlying Fund may remain concentrated in the banking industry until the purchase of new investments in the normal course of executing the investment strategy results in less than 25% of the total assets of the Portfolio or Underlying Fund consisting of banking industry securities. Similarly, in applying the banking industry policy, the Advisor will track the yield to maturity on eligible portfolio investments in the banking industry when the purchase of new investments in the normal course of executing the investment strategy of the Portfolio or Underlying Fund could result in it becoming concentrated and then will purchase such amount of eligible investments in the banking industry as would be consistent with the normal course of executing the investment strategy.

The types of bank and bank holding company obligations in which the Inflation Protection Securities Portfolio, Short-Term Extended Quality Portfolio, Intermediate-Term Extended Quality Portfolio and One-Year Portfolio may invest include: dollar-denominated certificates of deposit, bankers’ acceptances, commercial paper and other debt obligations issued in the United States provided such obligations meet each Portfolio’s established credit rating criteria as stated under

“Description of Investments of the Underlying Funds.” In addition, the Portfolio and each Underlying Fund is authorized to invest more than 25% of its total assets in Treasury bonds, bills and notes and obligations of federal agencies and instrumentalities. The Short-Duration Inflation Protected Securities Portfolio, Short-Term Extended Quality Portfolio and Intermediate-Term Extended Quality Portfolio also may invest in non-dollar denominated certificates.

Description of Investments of the Underlying Funds

The Short-Duration Inflation Protected Securities Portfolio may invest directly in the same categories of investments in which the Underlying Funds may invest. The following is a description of the categories of fixed income investments that may be acquired by the Underlying Funds in which the Short-Duration Inflation Protected Securities Portfolio invests:

	Permissible Categories:
One-Year Portfolio	1-10
Short-Term Extended Quality Portfolio	1,2,4,6-13
Intermediate-Term Extended Quality Portfolio	1,2,4,6-11,13

1. U.S. Government Obligations—Debt securities issued by the U.S. Treasury that are direct obligations of the U.S. Government, including bills, notes and bonds.

2. U.S. Government Agency Obligations—Issued or guaranteed by U.S. government-sponsored instrumentalities and federal agencies, which have different levels of credit support. The U.S. government agency obligations include, but are not limited to, securities issued by agencies and instrumentalities of the U.S. Government that are supported by the full faith and credit of the United States, such as the Federal Housing Administration and Ginnie Mae, including Ginnie Mae pass-through certificates. Other securities issued by agencies and instrumentalities sponsored by the U.S. Government may be supported only by the issuer’s right to borrow from the U.S. Treasury, subject to certain limits, such as securities issued by Federal Home Loan Banks, or are supported only by the credit of such agencies, such as Freddie Mac and Fannie Mae.

3. Corporate Debt Obligations—Nonconvertible corporate debt securities (e.g., bonds and debentures), which are issued by companies whose commercial paper is rated Prime1 by Moody’s or A1 or better by S&P or F1 or better by Fitch and dollar-denominated obligations of foreign issuers issued in the U.S. If the issuer’s commercial paper is unrated, then the debt security would have to be rated at least AA by S&P or Aa2 by Moody’s or AA by Fitch. If there is neither a commercial paper rating nor a rating of the debt security, then the Advisor must determine that the debt security is of comparable quality to equivalent issues of the same issuer rated at least AA or Aa2.

4. Bank Obligations—Obligations of U.S. banks and savings and loan associations and dollar-denominated obligations of U.S. subsidiaries and branches of foreign banks, such as certificates of deposit (including marketable variable rate certificates of deposit), time deposits and bankers’ acceptances. Bank certificates of deposit will be acquired only from banks having assets in excess of $1,000,000,000.

5. Commercial Paper—Rated, at the time of purchase, A1 or better by S&P or Prime1 by Moody’s, or F1 or better by Fitch or, if unrated, issued by a corporation having an outstanding unsecured debt issue rated Aaa by Moody’s or AAA by S&P or AAA by Fitch.

6. Repurchase Agreements—Instruments through which an Underlying Fund purchases securities (“underlying securities”) from a bank or a registered U.S. government securities dealer, with an agreement by the seller to repurchase the securities at an agreed price, plus interest, at a specified rate. The underlying securities will be limited to U.S. government and agency obligations described in (1) and (2) above. An Underlying Fund will not enter into a repurchase agreement with a duration of more than seven days if, as a result, more than 10% of the value of its total assets would be so invested. In addition, a repurchase agreement with a duration of more than seven days will be subject to illiquid securities policy of the Underlying Fund. Also, an Underlying Fund only will invest in repurchase agreements with a bank if the bank has at least $1,000,000,000 in assets and is approved by the Investment Committee of the Advisor. The Advisor will monitor the market value of the securities plus any accrued interest thereon so that they will at least equal the repurchase price.

7. Foreign Government and Agency Obligations—Bills, notes, bonds, and other debt securities issued or guaranteed by foreign governments, or their agencies and instrumentalities.

8. Supranational Organization Obligations—Debt securities of supranational organizations such as the European Investment Bank, the Inter-American Development Bank or the World Bank, which are chartered to promote economic development.

9. Eurodollar Obligations—Debt securities of domestic or foreign issuers denominated in U.S. dollars but not trading in the United States.

10. Money Market Funds—An Underlying Fund may invest in affiliated and unaffiliated registered and unregistered money market funds.

11. Corporate Debt Obligations—Nonconvertible corporate debt securities (e.g., bonds and debentures), which have received an investment grade rating by Moody’s, Fitch, or S&P, or if unrated, have been determined by the Advisor to be of comparable quality.

12. Commercial Paper—Rated, at the time of purchase, A3 or better by S&P or Prime3 or better by Moody’s, or F3 or better by Fitch or, if unrated, issued by a corporation having an outstanding unsecured debt issue rated at least Baa3 by Moody’s or BBB- by S&P or Fitch.

13. Foreign Issuer Obligations—Debt securities of non-U.S. issuers that have received a rating of BBB- or better by S&P or Fitch or Baa3 or better by Moody’s, or, if unrated, have been determined by the Advisor to be of comparable quality.

The categories of investments that may be acquired by an Underlying Fund may include both fixed and floating rate securities. Floating rate securities bear interest at rates that vary with prevailing market rates. Interest rate adjustments are made periodically (e.g., every six months), usually based on a money market index such as the London Interbank Offered Rate (LIBOR) or the Treasury bill rate. The Short-Duration Inflation Protected Securities Portfolio may invest directly in the same types of investments that are described above as eligible investments for its Underlying Funds.

Other Information

Commodity Pool Operator Exemption

The Portfolio and each Underlying Fund is operated by a person that has claimed an exclusion from the definition of the term “commodity pool operator” under the Commodity Exchange Act (“CEA”) with respect to the Portfolio and Underlying Funds described in this prospectus, and, therefore, such person is not subject to registration or regulation as a pool operator under the CEA with respect to such Portfolio and Underlying Funds.

Fund of Funds Portfolio Turnover

Because the Short-Duration Inflation Protected Securities Portfolio is new, information about its portfolio turnover rate is not yet available. Future disclosure of the portfolio turnover rate provided for the Short-Duration Inflation Protected Securities Portfolio under the heading “Portfolio Turnover” will be unaudited. The portfolio turnover rate will be derived from the portfolio turnover rate of the Underlying Funds in which the Portfolio invests.

SECURITIES LOANS

The Portfolio and the Underlying Funds are authorized to lend securities to qualified brokers, dealers, banks and other financial institutions for the purpose of earning additional income. While the Portfolio or an Underlying Fund may earn additional income from lending securities, such activity is incidental to the investment objective of the Portfolio or Underlying Fund. The value of securities loaned may not exceed 33 1/3% of the value of the Portfolio’s or Underlying Fund’s total assets, which includes the value of collateral received. To the extent the Portfolio or an Underlying Fund loans a portion of its securities, the Portfolio or Underlying Fund will receive collateral consisting generally of cash or U.S. government securities, which will be maintained by marking to market daily in an amount equal to at least (i) 100% of the current market value of the loaned securities with respect to securities of the U.S. Government or its agencies, (ii) 102% of the current market value of the loaned securities with respect to U.S. securities, and (iii) 105% of the current market value of the loaned securities with respect to foreign securities. Subject to its stated investment policies, the Portfolio or an Underlying Fund will generally invest the cash collateral received for the loaned securities in The DFA Short Term Investment Fund (the “Money

Market Series”), an affiliated registered money market fund advised by the Advisor for which the Advisor receives a management fee of 0.05% of the average daily net assets of the Money Market Series. The Portfolio and Underlying Funds may also invest such collateral in securities of the U.S. Government or its agencies, repurchase agreements collateralized by securities of the U.S. Government or its agencies, and unaffiliated registered and unregistered money market funds. For purposes of this paragraph, agencies include both agency debentures and agency mortgage backed securities.

In addition, the Portfolio or an Underlying Fund will be able to terminate the loan at any time and will receive reasonable interest on the loan, as well as amounts equal to any dividends, interest or other distributions on the loaned securities. However, dividend income received from loaned securities may not be eligible to be taxed at qualified dividend income rates. The Portfolio or an Underlying Fund will be entitled to recall a loaned security in time to vote proxies or otherwise obtain rights to vote proxies of loaned securities if the Portfolio or Underlying Fund knows a material event will occur. In the event of the bankruptcy of the borrower, the Portfolio or an Underlying Fund could experience delay in recovering the loaned securities or only recover cash or a security of equivalent value. See “Principal Risks—Securities Lending Risk” for a discussion of the risks related to securities lending.

MANAGEMENT OF THE FUND

The Advisor serves as investment advisor to the Portfolio and each of the Underlying Funds. Pursuant to an Investment Advisory Agreement with the Portfolio and each Underlying Fund, the Advisor is responsible for the management of their respective assets. The Portfolio and Underlying Funds are managed using a team approach. The investment team includes the Investment Committee of the Advisor, portfolio managers and trading personnel.

The Investment Committee is composed primarily of certain officers and directors of the Advisor who are appointed annually. As of the date of this Prospectus, the Investment Committee has eleven members. Investment strategies for the Portfolio and Underlying Funds are set by the Investment Committee, which meets on a regular basis and also as needed to consider investment issues. The Investment Committee also sets and reviews all investment related policies and procedures and approves any changes in regards to approved countries, security types and brokers.

In accordance with the team approach used to manage the portfolios, the portfolio managers and portfolio traders implement the policies and procedures established by the Investment Committee. The portfolio managers and portfolio traders also make daily investment decisions regarding the portfolios based on the parameters established by the Investment Committee. The individuals named in the Portfolio’s “INVESTMENT ADVISOR/PORTFOLIO MANAGEMENT” section coordinate the efforts of all other portfolio managers or trading personnel with respect to the day-to-day management of the Portfolio.

Mr. Plecha is a Senior Portfolio Manager and Vice President of the Advisor and a member of the Investment Committee. Mr. Plecha received his BS from the University of Michigan at Ann Arbor in 1983 and his MBA from the University of California at Los Angeles in 1987. Mr. Plecha has been a portfolio manager since 1989 and responsible for the fixed income portfolios since the end of 1991.

Mr. Kolerich is a Senior Portfolio Manager and Vice President of the Advisor and a member of the Investment Committee. Mr. Kolerich has an MBA from the University of Chicago Booth School of Business and a BS from Northern Illinois University. Mr. Kolerich joined the Advisor as a portfolio manager in 2001 and has been responsible for the fixed income portfolios since 2012.

The Portfolio’s SAI provides information about each portfolio manager’s compensation, other accounts managed by the portfolio manager, and the portfolio manager’s ownership of Fund shares.

The Advisor provides the Portfolio and Underlying Funds with a trading department and selects brokers and dealers to effect securities transactions. Securities transactions are placed with a view to obtaining best price and execution. The Advisor’s address is 6300 Bee Cave Road, Building One, Austin, TX 78746. A discussion regarding the basis for the Board approving the investment management agreement with respect to the Portfolio will be available in future annual or semi-annual reports for the Portfolio.

The Fund bears all of its own costs and expenses, including: services of its independent registered public accounting firm, legal counsel, brokerage fees, commissions and transfer taxes in connection with the acquisition and disposition of

portfolio securities, taxes, insurance premiums, costs incidental to meetings of its shareholders and directors or trustees, the cost of filing its registration statements under the federal securities laws and the cost of any filings required under state securities laws, reports to shareholders, and transfer and dividend disbursing agency, administrative services and custodian fees, except as provided in the Fee Waiver and Expense Assumption Agreements for certain portfolios of the Fund, including the Portfolio. Expenses allocable to a particular portfolio or class of a portfolio are so allocated. The expenses of a Fund which are not allocable to a particular portfolio or class of a portfolio are to be borne by each portfolio or class of a portfolio of the Fund on the basis of its relative net assets.

The Advisor has been engaged in the business of providing investment management services since May 1981. The Advisor is currently organized as a Delaware limited partnership and is controlled and operated by its general partner, Dimensional Holdings Inc., a Delaware corporation. The Advisor controls Dimensional Fund Advisors Ltd. (“DFAL”) and DFA Australia Limited (“DFA Australia”). As of January 31, 2013, assets under management for all Dimensional affiliated advisors totaled approximately $270 billion.

Management Fees

The “Annual Fund Operating Expenses” table describes the anticipated fees to be incurred by the Portfolio for the services provided by the Advisor for the first full fiscal year.

Sub-Advisors

Pursuant to a Sub-Advisory Agreement with the Advisor, DFA Australia, Level 43 Gateway, 1 Macquarie Place, Sydney, New South Wales 2000, Australia, at the request of the Advisor, has the authority and responsibility to select brokers and dealers to execute securities transactions for the Portfolio. DFA Australia’s duties, if requested by the Advisor, include the maintenance of a trading desk for the Portfolio and the determination of the best and most efficient means of executing securities transactions. On at least a semi-annual basis, the Advisor reviews the holdings of the Portfolio and reviews the trading process and the execution of securities transactions. The Advisor is responsible for determining those securities which are eligible for purchase and sale by the Portfolio and may delegate this task, subject to its own review, to DFA Australia. DFA Australia maintains and furnishes to the Advisor information and reports on Japanese and Asia Pacific Rim small companies, including its recommendations of securities to be added to the securities that are eligible for purchase by the Portfolio as well as making recommendations and elections on corporate actions.

Pursuant to a Sub-Advisory Agreement with the Advisor, DFAL, 20 Triton Street, Regent’s Place, London, NW13BF, United Kingdom, a company that is organized under the laws of England, at the request of the Advisor, has the authority and responsibility to select brokers or dealers to execute securities transactions for the Portfolio. DFAL’s duties, if requested by the Advisor, include the maintenance of a trading desk for the Portfolio and the determination of the best and most efficient means of executing securities transactions. On at least a semi-annual basis, the Advisor reviews the holdings of the Portfolio and reviews the trading process and the execution of securities transactions. The Advisor is responsible for determining those securities which are eligible for purchase and sale by the Portfolio and may delegate this task, subject to its own review, to DFAL. DFAL maintains and furnishes to the Advisor information and reports on United Kingdom and European small companies, including its recommendations of securities to be added to the securities that are eligible for purchase by the Portfolio as well as making recommendations and elections on corporate actions. DFAL is a member of the Financial Services Authority, a self-regulatory organization for investment managers operating under the laws of England.

Fee Waiver and Expense Assumption Agreement

Pursuant to a Fee Waiver and Expense Assumption Agreement (the “Fee Waiver Agreement”) for the Portfolio, the Advisor has contractually agreed to waive up to the full amount of the Portfolio’s management fee of 0.20% to the extent necessary to offset the proportionate share of the management fees paid by the Portfolio through its investment in other funds managed by the Advisor (the “Underlying Funds”). In addition, under the Fee Waiver Agreement, the Advisor has also agreed to waive all or a portion of the management fee and to assume the ordinary operating expenses of a class of the Portfolio (including the expenses that the Portfolio bears as a shareholder of other funds managed by the Advisor but excluding the expenses that the Portfolio incurs indirectly through its investment in unaffiliated investment companies and excluding any applicable 12b-1 fees) (“Portfolio Expenses”) to the extent necessary to limit the Portfolio Expenses of a class of the Portfolio to 0.24% of the average net assets of a class of the Portfolio on an annualized basis (the “Expense Limitation Amount”). The Fee Waiver Agreement for the Portfolio will remain in effect through February 28, 2015, and may not be terminated by the Advisor prior to that date. At any time that the Portfolio’s annualized Portfolio Expenses are less than the Portfolio’s Expense

Limitation Amount, described above, the Advisor retains the right to recover any fees previously waived and/or expenses previously assumed to the extent that such recovery will not cause the annualized Portfolio Expenses of a class of the Portfolio to exceed the Expense Limitation Amount. The Portfolio is not obligated to reimburse the Advisor for fees previously waived or expenses previously assumed by the Advisor more than thirty-six months before the date of such reimbursement.

DIVIDENDS, CAPITAL GAINS DISTRIBUTIONS AND TAXES

Dividends and Distributions. The Portfolio intends to qualify each year as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). As a regulated investment company, the Portfolio generally pays no federal income tax on the income and gains the Portfolio distributes to you. Dividends from net investment income and any net realized capital gains of the Portfolio (after any reductions for available capital loss carryforwards) are distributed annually, typically in December. The Portfolio may distribute such income dividends and capital gains more frequently, if necessary, in order to reduce or eliminate federal excise or income taxes on the Portfolio.

Capital gains distributions may vary considerably from year to year as a result of the Portfolio’s normal investment activities and cash flows. During a time of economic volatility, the Portfolio may experience capital losses and unrealized depreciation in value of investments, the effect of which may be to reduce or eliminate capital gains distributions for a period of time. Even though the Portfolio may experience a current year loss, it may nonetheless distribute prior year capital gains.

You will automatically receive all income dividends and capital gains distributions in additional shares of the Portfolio whose shares you hold at net asset value (as of the business date following the dividend record date), unless, upon written notice to the Advisor and completion of account information, you select one of the options listed below:

Income Option—to receive income dividends in cash and capital gains distributions in additional shares at net asset value.

Capital Gains Option—to receive capital gains distributions in cash and income dividends in additional shares at net asset value.

Cash Option—to receive both income dividends and capital gains distributions in cash.

Annual Statements. Each year, you will receive a statement that shows the tax status of distributions you received the previous calendar year. Distributions declared in December to shareholders of record in such month, but paid in January, are taxable as if they were paid in December.

Avoid “Buying A Dividend.” At the time you purchase your Portfolio shares, the Portfolio’s net asset value may reflect undistributed income, undistributed capital gains, or net unrealized appreciation in value of portfolio securities held by the Portfolio. A subsequent distribution to you of such amounts, although constituting a return of your investment, would be taxable. Buying shares in the Portfolio just before it declares an income dividend or capital gains distribution is sometimes known as “buying a dividend.”

Tax Considerations. This discussion of “Tax Considerations” should be read in conjunction with the remaining subsections below containing additional information. Also, unless otherwise indicated, the discussion below with respect to the Portfolio includes its pro rata share of the dividends and distributions paid by the Underlying Funds.

In general, if you are a taxable investor, Portfolio distributions are taxable to you as ordinary income, capital gains, or some combination of both. This is true whether you reinvest your distributions in additional Portfolio shares or receive them in cash.

For federal income tax purposes, Portfolio distributions of short-term capital gains are taxable to you as ordinary income. Portfolio distributions of long-term capital gains are taxable to you as long-term capital gains no matter how long you have owned your shares. A portfolio with a high portfolio turnover rate (a measure of how frequently assets within a portfolio are bought and sold) is more likely to generate short-term capital gains than a portfolio with a low portfolio turnover rate. A portion of income dividends reported by the Portfolio as qualified dividend income may be eligible for taxation by individual shareholders at long-term capital gain rates provided certain holding period requirements are met. Because the income of the Portfolio primarily is derived from investments earning interest rather than dividend income, generally none or

only a small portion of the income dividends paid to you by the Portfolio is anticipated to be qualified dividend income eligible for taxation by individuals at long-term capital gain tax rates

If the Portfolio qualifies to pass through to you the tax benefits from foreign taxes it pays on its investments, and elects to do so, then any foreign taxes it pays on these investments may be passed through to you as a foreign tax credit.

Sale or Redemption of Portfolio Shares. The sale of shares of the Portfolio is a taxable event and may result in a capital gain or loss to you. Capital gain or loss may be realized from an ordinary redemption of shares or an exchange of shares between two Portfolios. Any loss incurred on the sale or exchange of the Portfolio’s shares, held for six months or less, will be treated as a long-term capital loss to the extent of capital gain dividends received with respect to such shares.

Beginning with the 2012 calendar year, the Portfolio will be required to report to you and the IRS annually on Form 1099-B not only the gross proceeds of Portfolio shares you sell or redeem but also the cost basis for shares purchased or acquired on or after January 1, 2012. Cost basis will be calculated using the Portfolio’s default method of average cost, unless you instruct the Portfolio to use a different calculation method. Shareholders should carefully review the cost basis information provided by the Portfolio and make any additional basis, holding period or other adjustments that are required when reporting these amounts on their federal income tax returns. If your account is held by your investment representative (financial advisor or other broker), please contact that representative with respect to reporting of cost basis and available elections for your account. Tax-advantaged retirement accounts will not be affected.

Medicare Tax. For taxable years beginning after December 31, 2012, an additional 3.8% Medicare tax will be imposed on certain net investment income (including ordinary dividends and capital gain distributions received from the Portfolio and net gains from redemptions or other taxable dispositions of Portfolio shares) of U.S. individuals, estates and trusts to the extent that such person’s “modified adjusted gross income” (in the case of an individual) or “adjusted gross income” (in the case of an estate or trust) exceeds a threshold amount.

Backup Withholding. By law, the Portfolio may be required to withhold 28% of taxable dividends, capital gains distributions, and redemption proceeds paid to you if you do not provide your proper taxpayer identification number and certain required certifications. You may avoid this withholding requirement by providing and certifying on the account registration form your correct Taxpayer Identification Number and by certifying that you are not subject to backup withholding and are a U.S. person (including a U.S. resident alien). The Portfolio must also withhold if the Internal Revenue Service instructs it to do so.

State and Local Taxes. In addition to federal taxes, you may be subject to state and local taxes on distributions from the Portfolio and on gains arising on redemption or exchange of the Portfolio’s shares. Distributions of interest income and capital gains realized from certain types of U.S. government securities may be exempt from state personal income taxes. To the extent an Underlying Fund invests in U.S. government obligations, distributions derived from interest on these obligations and paid to its corresponding Portfolio and, in turn, to shareholders are unlikely to be exempt from state and local income tax.

Non-U.S. Investors. Non-U.S. investors may be subject to U.S. withholding tax at a 30% or lower treaty rate and are subject to special U.S. tax certification requirements to avoid backup withholding and claim any treaty benefits. Exemptions from U.S. withholding tax are provided for capital gain dividends paid by the Portfolio from long-term capital gains, if any, exempt-interest dividends, and, with respect to taxable years of the Portfolio that begin before January 1, 2014 (unless such provision is extended or made permanent), interest-related dividends paid by the Portfolio from its qualified net interest income from U.S. sources and short-term capital gain dividends. However, notwithstanding such exemptions from U.S. withholding at the source, any such dividends and distributions of income and capital gains will be subject to backup withholding at a rate of 28% if you fail to properly certify that you are not a U.S. person. Non-U.S. investors also may be subject to U.S. estate tax.

Other Reporting and Withholding Requirements. The Foreign Account Tax Compliance Act (“FATCA”) requires the reporting to the Internal Revenue Service of certain direct and indirect ownership of foreign financial accounts by U.S. persons. Failure to provide this required information can result in a generally nonrefundable 30% tax on: (a) income dividends paid by the Portfolio after December 31, 2013 and (b) certain capital gain distributions (including proceeds arising from the sale of Portfolio shares) paid by the Portfolio after December 31, 2016 to certain “foreign financial institutions” and “non-financial foreign entities.”

This discussion of “DIVIDENDS, CAPITAL GAINS DISTRIBUTIONS AND TAXES” is not intended or written to be used as tax advice. Because everyone’s tax situation is unique, you should consult your tax professional about federal, state, local, or foreign tax consequences before making an investment in the Portfolio. Prospective investors should also consult the SAI.

PURCHASE OF SHARES

Cash Purchases

Investors may purchase Institutional Class shares of the Portfolio by first contacting the Advisor at (888) 576-1167 or (512) 306-7400 to notify the Advisor of the proposed investment. Investors that invest through a financial intermediary should contact such intermediary with regard to purchase instructions. The Portfolio generally is available for investment only by institutional clients, clients of registered investment advisors, clients of financial institutions, and a limited number of certain other investors, each as approved from time to time by the Advisor (“Eligible Investors”). Eligible Investors include employees, former employees, shareholders, and directors of the Advisor and the Fund and friends and family members of such persons. All investments are subject to approval of the Advisor, and all investors must complete and submit the necessary account registration forms in good order. The Fund reserves the right to reject any initial or additional investment and to suspend the offering of shares of the Portfolio.

“Good order” with respect to the purchase of shares means that (1) a fully completed and properly signed Account Registration Form and any additional supporting legal documentation required by the Advisor have been received in legible form, and (2) the Advisor has been notified of the purchase by telephone and, if the Advisor so requests, also in writing, no later than the close of regular trading on the NYSE (normally, 4:00 p.m. ET) on the day of the purchase. If an order to purchase shares must be canceled due to nonpayment, the purchaser will be responsible for any loss incurred by the Fund arising out of such cancellation. To recover any such loss, the Fund reserves the right to redeem shares owned by any purchaser whose order is canceled, and such purchaser may be prohibited or restricted in the manner of placing further orders.

Investors having an account with a bank that is a member or a correspondent of a member of the Federal Reserve System may purchase shares by first calling the Advisor at (888) 576-1167 or (512) 306-7400 to notify the Advisor of the proposed investment, then requesting the bank to transmit immediately available funds (federal funds) by wire to the Fund’s custodian for the account of DFA Investment Dimensions Group Inc. (specify the Portfolio). Additional investments also may be made through the wire procedure by first notifying the Advisor. Investors who wish to purchase shares of the Portfolio by check should first call the Advisor at (888) 576-1167 or (512) 306-7400 for additional instructions.

Payment of the total amount due should be made in U.S. dollars. However, subject to approval by the Advisor, payment may be made in any freely convertible currency and the necessary foreign exchange transactions will be arranged on behalf of, and at the expense of, the applicant. Applicants settling in any currency other than U.S. dollars are advised that a delay in processing a purchase or redemption may occur to allow for currency conversion.

Shares also may be purchased and sold by individuals through securities firms that may charge a service fee or commission for such transactions. No such fee or commission is charged on shares that are purchased or redeemed directly from the Fund. Investors who are clients of investment advisory organizations may also be subject to investment advisory fees under their own arrangements with such organizations.

In-Kind Purchases

If accepted by the Fund, shares of the Portfolio may be purchased in exchange for securities that are eligible for acquisition by the Portfolio (or its corresponding Underlying Funds) or otherwise represented in their portfolios as described in this Prospectus or as otherwise consistent with the Fund’s policies or procedures or in exchange for local currencies in which such securities are denominated. Securities and local currencies accepted by the Fund for exchange and Fund shares to be issued in the exchange will be valued as set forth under “VALUATION OF SHARES” at the time of the next determination of net asset value after such acceptance. All dividends, interest, subscription, or other rights pertaining to such securities shall become the property of the Portfolio whose shares are being acquired and must be delivered to the Fund by

the investor upon receipt from the issuer. Investors who desire to purchase shares of the Portfolio with local currencies should first contact the Advisor.

The Fund will not accept securities in exchange for shares of the Portfolio unless: (1) such securities are, at the time of the exchange, eligible to be included, or otherwise represented, in the Portfolio and current market quotations are readily available for such securities; (2) the investor represents and agrees that all securities offered to be exchanged are not subject to any restrictions upon their sale by the Portfolio under the Securities Act of 1933 or under the laws of the country in which the principal market for such securities exists, or otherwise; and (3) at the discretion of the Fund, the value of any such security (except U.S. government securities) being exchanged, together with other securities of the same issuer owned by the Portfolio, may not exceed 5% of the net assets of the Portfolio immediately after the transaction.

A gain or loss for federal income tax purposes will generally be realized by investors who are subject to federal taxation upon the exchange, depending upon the cost of the securities or local currency exchanged. Investors interested in such exchanges should contact the Advisor. Purchases of shares will be made in full and fractional shares calculated to three decimal places. In the interest of economy and convenience, certificates for shares will not be issued.

POLICY REGARDING EXCESSIVE OR SHORT-TERM TRADING

The Portfolio is designed for long-term investors and is not intended for investors that engage in excessive short-term trading activity that may be harmful to the Portfolio, including but not limited to market timing. Short-term or excessive trading into and out of the Portfolio can disrupt portfolio management strategies, harm performance and increase Portfolio expenses for all shareholders, including long-term shareholders who do not generate these costs.

The Board of Directors of the Fund (the “Board”) has adopted a policy (the “Trading Policy”) and the Advisor and DFA Securities LLC (collectively, “Dimensional”) and Dimensional’s agents have implemented the following procedures, which are designed to discourage and prevent market timing or excessive short-term trading in the Fund: (i) trade activity monitoring and purchase blocking procedures; and (ii) use of fair value pricing.

The Fund, Dimensional and their agents monitor trades and flows of money in and out of the Portfolio from time to time in an effort to detect excessive short-term trading activities, and for consistent enforcement of the Trading Policy. The Fund reserves the right to take the actions necessary to stop excessive or disruptive trading activities, including refusing or canceling purchase or exchange orders for any reason, without prior notice, particularly purchase or exchange orders that the Fund believes are made on behalf of market timers. The Fund, Dimensional and their agents reserve the right to restrict, refuse or cancel any purchase or exchange request made by an investor indefinitely if the Fund or Dimensional believes that any combination of trading activity in the accounts is potentially disruptive to a Portfolio. In making such judgments, the Fund and Dimensional seek to act in a manner that is consistent with the interests of shareholders. For purposes of applying these procedures, Dimensional may consider an investor’s trading history in the Portfolio, and accounts under common ownership, influence or control.

In addition to the Fund’s general ability to restrict potentially disruptive trading activity as described above, the Fund also has adopted purchase blocking procedures. Under the Fund’s purchase blocking procedures, where an investor has engaged in any two purchases and two redemptions (including redemptions that are part of an exchange transaction) in a Portfolio in any rolling 30 calendar day monitoring period (i.e., two “round trips”), the Fund and Dimensional intend to block the investor from making any additional purchases in that Portfolio for 90 calendar days (a “purchase block”). If implemented, a purchase block will begin at some point after the transaction that caused the investor to have engaged in the prohibited two round-trips is detected by the Fund, Dimensional, or their agents. The Fund and Dimensional are permitted to implement a longer purchase block, or permanently bar future purchases by an investor, if they determine that it is appropriate.

Under the Fund’s purchase blocking procedures, the following purchases and redemptions will not trigger a purchase block: (i) purchases and redemptions of shares having a value in each transaction of less than $25,000; (ii) purchases and redemptions by U.S. registered investment companies that operate as fund of funds and non-U.S. investment companies that operate as fund of funds that the Fund or Dimensional, in their sole discretion, have determined are not designed and/or are not serving as vehicles for excessive short-term or other disruptive trading (in each case, the fund of funds shall agree to be subject to monitoring by Dimensional); (iii) purchases and redemptions by a feeder portfolio of a master fund’s shares; (iv) systematic or automated transactions where the shareholder, financial advisor or investment

fiduciary does not exercise direct control over the investment decision; (v) retirement plan contributions, loans, loan repayments and distributions (including hardship withdrawals) identified as such in the retirement plan recordkeeper’s system; (vi) purchase transactions involving transfers of assets, rollovers, Roth IRA conversions and IRA recharacterizations; (vii) purchases of shares with Portfolio dividends or capital gain distributions; (viii) transfers and reregistrations of shares within the same Portfolio; and (ix) transactions by 529 Plans. Notwithstanding the Fund’s purchase blocking procedures, all transactions in Portfolio shares are subject to the right of the Fund and Dimensional to restrict potentially disruptive trading activity (including purchases and redemptions described above that will not be subject to the purchase blocking procedures).

The Fund, Dimensional or their designees will have the ability, pursuant to Rule 22c-2 under the 1940 Act, to request information from financial intermediaries, such as 401(k) plan administrators, trust companies and broker dealers (together, “Intermediaries”), concerning trades placed in omnibus and other multi-investor accounts (together, “Omnibus Accounts”), in order to attempt to monitor trades that are placed by the underlying shareholders of these Omnibus Accounts. The Fund, Dimensional and their designees will use the information obtained from the Intermediaries to monitor trading in the Fund and to attempt to identify shareholders in Omnibus Accounts engaged in trading that is inconsistent with the Trading Policy or otherwise not in the best interests of the Fund. The Fund, Dimensional or their designees, when they detect trading patterns in shares of the Fund that may constitute short-term or excessive trading, will provide written instructions to the Intermediary to restrict or prohibit further purchases or exchanges of shares of the Portfolio by a shareholder that has been identified as having engaged in excessive or short-term transactions in the Portfolio’s shares (directly or indirectly through the Intermediary’s account) that violate the Trading Policy.

The ability of the Fund and Dimensional to impose these limitations, including the purchase blocking procedures, on investors investing through Intermediaries is dependent on the receipt of information necessary to identify transactions by the underlying investors and the Intermediary’s cooperation in implementing the Trading Policy. Investors seeking to engage in excessive short-term trading practices may deploy a variety of strategies to avoid detection, and despite the efforts of the Fund and Dimensional to prevent excessive short-term trading, there is no assurance that the Fund, Dimensional or their agents will be able to identify those shareholders or curtail their trading practices. The ability of the Fund, Dimensional and their agents to detect and limit excessive short-term trading also may be restricted by operational systems and technological limitations.

Transactions in certain rebalancing programs and asset allocation programs, or fund-of-funds products, may be exempt from the Trading Policy subject to approval by the CCO. In addition, the purchase blocking procedures will not apply to a redemption transaction in which the Portfolio distributes portfolio securities to a shareholder in-kind, where the redemption will not disrupt the efficient portfolio management of the Portfolio/Underlying Fund and the redemption is consistent with the interests of the remaining shareholders of the Portfolio/Underlying Fund.

The purchase blocking procedures of the Trading Policy do not apply to shareholders whose shares are held on the books of certain Intermediaries that have not expressly adopted procedures to implement this Policy. The Fund and Dimensional may work with Intermediaries to implement purchase blocking procedures or other procedures that the Fund and Dimensional determine are reasonably designed to achieve the objective of this Trading Policy. At the time the Intermediaries adopt these procedures, shareholders whose accounts are on the books of such Intermediaries will be subject to the Trading Policy’s purchase blocking procedures or another frequent trading policy that achieves the objective of the purchase blocking procedures. Investors that invest in the Portfolio through an Intermediary should contact the Intermediary for information concerning the policies and procedures that apply to the investor.

As of the date of this Prospectus, the ability of the Fund and Dimensional to apply the purchase blocking procedures on purchases by all investors and the ability of the Fund and Dimensional to monitor trades through Omnibus Accounts maintained by Intermediaries may be restricted due to systems limitations of both the Fund’s service providers and the Intermediaries. The Fund expects that the application of the Trading Policy as described above, including the purchase blocking procedures (subject to the limitations described above), will be able to be implemented by Intermediaries in compliance with Rule 22c-2 under the 1940 Act.

In addition to monitoring trade activity, the Board has adopted fair value pricing procedures that govern the pricing of the securities of the Portfolio and Underlying Funds. These procedures are designed to help ensure that the prices at which Portfolio shares are purchased and redeemed are fair, and do not result in dilution of shareholder interests or other harm to shareholders. See the discussion under “VALUATION OF SHARES—Net Asset Value” for additional details regarding fair value pricing of the Portfolio’s securities.

Although the procedures are designed to discourage excessive short-term trading, none of the procedures individually nor all of the procedures taken together can completely eliminate the possibility that excessive short-term trading activity in a Portfolio may occur. The Portfolio and Underlying Funds do not knowingly accommodate excessive or disruptive trading activities, including market timing.

VALUATION OF SHARES

Net Asset Value

The net asset value per share of each class of the Portfolio and the net asset value per share of each Underlying Fund is calculated after the close of the NYSE (normally, 4:00 p.m. ET) by dividing the total value of the investments and other assets of the Portfolio or Underlying Fund less any liabilities, by the total outstanding shares of the stock of the respective Portfolio or Underlying Fund. The Portfolio and Underlying Funds generally calculate their net asset values per share and accept purchase and redemption orders on days that the NYSE is open for trading. Note: The time at which transactions and shares are priced may be changed in case of an emergency or if the NYSE closes at a time other than 4:00 p.m. ET.

The value of the shares of the Portfolio will fluctuate in relation to its own investment experience and the investment experience of the Underlying Funds in which the Portfolio invests. Securities held by the Portfolio and Underlying Funds will be valued in accordance with applicable laws and procedures adopted by the Board of Directors, and generally, as described below.

Debt securities will be valued on the basis of prices provided by one or more pricing services or other reasonably reliable sources, including broker/dealers that typically handle the purchase and sale of such securities using data, reflecting the earlier closing of the principal markets for those securities. Securities which are traded over-the-counter and on a stock exchange generally will be valued according to the broadest and most representative market, and it is expected that for bonds and other fixed income securities, this ordinarily will be the over-the-counter market. Net asset value includes interest on fixed income securities which is accrued daily. Generally, securities issued by open-end investment companies, such as the Underlying Funds, are valued using their respective net asset values or public offering prices, as appropriate, for purchase orders placed at the close of the NYSE.

The value of the securities and other assets of the Portfolio and Underlying Funds for which no market quotations are readily available (including restricted securities), or for which market quotations have become unreliable, are determined in good faith at fair value in accordance with procedures adopted by the Board of Directors. Fair value pricing may also be used if events that have a significant effect on the value of an investment (as determined in the discretion of the Investment Committee of the Advisor) occur before the net asset value is calculated. When fair value pricing is used, the prices of securities used by the Portfolio and Underlying Funds may differ from the quoted or published prices for the same securities on their primary markets or exchanges.

Valuing securities at fair value involves greater reliance on judgment than valuing securities that have readily available market quotations. There can be no assurance that the Portfolio or an Underlying Fund could obtain the fair value assigned to a security if it were to sell the security at approximately the time at which the Portfolio or Underlying Fund determines its net asset value per share. As a result, the sale or redemption by the Portfolio or Underlying Fund of its shares at net asset value, at a time when a holding or holdings are valued at fair value, may have the effect of diluting or increasing the economic interest of existing shareholders.

The net asset values per share of the Five-Year Global Portfolio and Short-Term Extended Quality Portfolio are expressed in U.S. dollars by translating the net assets of each Underlying Fund using the mean of the most recent bid and asked prices for the dollar as quoted by generally recognized reliable sources. Since these Underlying Funds own securities that are primarily listed on foreign exchanges which may trade on days when the Portfolio does not price its shares, the net asset values of these Underlying Funds may change on days when shareholders will not be able to purchase or redeem shares.

Futures contracts are valued using the settlement price established each day on the exchange on which they are traded. The value of such futures contracts held by the Portfolio or an Underlying Fund is determined each day as of such close.

Public Offering Price

Provided that the transfer agent has received the investor’s Account Registration Form in good order and the custodian has received the investor’s payment, shares of the Portfolio selected will be priced at the public offering price, which is the net asset value of the shares next determined after receipt of the investor’s funds by the custodian. The transfer agent or the Fund may, from time to time, appoint sub-transfer agents or various financial intermediaries (“Intermediaries”) for the receipt of purchase orders, redemption orders, and funds from certain investors. Intermediaries, in turn, are authorized to designate other financial intermediaries (“Subdesignees”) to receive purchase and redemption orders for the Portfolio’s shares from investors. With respect to such investors, the shares of the Portfolio will be priced at the public offering price calculated after receipt of the purchase order by the Intermediary or Subdesignee, as applicable, that is authorized to receive purchase orders. If the investor buys shares through an Intermediary or a Subdesignee, the purchase price will be the public offering price next calculated after the Intermediary or Subdesignee, as applicable, receives the order, rather than on the day the custodian receives the investor’s payment (provided that the Intermediary or Subdesignee, as applicable, has received the investor’s purchase order in good order, and the investor has complied with the Intermediary’s or Subdesignee’s payment procedures). No reimbursement fee or sales charge is imposed on purchases. If an order to purchase shares must be canceled due to non-payment, the purchaser will be responsible for any loss incurred by the Portfolio arising out of such cancellation. The Fund reserves the right to redeem shares owned by any purchaser whose order is canceled to recover any resulting loss to the Portfolio and may prohibit or restrict the manner in which such purchaser may place further orders.

EXCHANGE OF SHARES

Investors may exchange Institutional Class shares of the Portfolio for Institutional Class shares of another eligible portfolio by first contacting the Advisor at (888) 576-1167 or (512) 306-7400 to notify the Advisor of the proposed exchange, and then sending a letter of instruction to DFA Investment Dimensions Group Inc. A letter of instruction for an exchange of shares may be sent by mail to the following: Attn: Client Operations, 6300 Bee Cave Road, Building One, Austin, TX 78746. Shareholders that invest in the Portfolio through a financial intermediary should contact their financial intermediary for information regarding exchanges.

Exchanges are accepted into those portfolios that are eligible for the exchange privilege. Investors may contact the Advisor at the above-listed phone number for more information on such exchanges, for a list of those portfolios that accept exchanges, and to request a copy of the prospectuses of other portfolios of the Fund or Dimensional Investment Group Inc. that may be offered in an exchange. There is no fee imposed on an exchange. However, the Fund reserves the right to impose an administrative fee in order to cover the costs incurred in processing an exchange. Any such fee will be disclosed in the Prospectus. An exchange is treated as a redemption and a purchase. Therefore, an investor could realize a taxable gain or a loss on the transaction. The Fund reserves the right to revise or terminate the exchange privilege, or limit the amount of or reject any exchange, as deemed necessary, at any time.

The exchange privilege is not intended to afford shareholders a way to speculate on short-term movements in the markets. Accordingly, in order to prevent excessive use of the exchange privilege that may potentially disrupt the management of the Portfolio or otherwise adversely affect the Fund, any proposed exchange will be subject to the approval of the Advisor. Such approval will depend on: (i) the size of the proposed exchange; (ii) the prior number of exchanges by that shareholder; (iii) the nature of the underlying securities and the cash position of the portfolios involved in the proposed exchange; (iv) the transaction costs involved in processing the exchange; and (v) the total number of redemptions by exchange already made out of the Portfolio. Excessive use of the exchange privilege is defined as any pattern of exchanges among portfolios by an investor that evidences market timing.

The redemption and purchase prices of shares redeemed and purchased by exchange, respectively, are the net asset values next determined after the Advisor has received a letter of instruction in good order. “Good order” means a completed letter of instruction specifying the dollar amount to be exchanged, signed by all registered owners (or representatives thereof) of the shares; and if a Fund does not have on file the authorized signatures for the account, proof of authority. Exchanges will be accepted only if stock certificates have not been issued and the shares of the Portfolio being acquired are registered in the investor’s state of residence.

REDEMPTION OF SHARES

Redemption Procedure

Investors who desire to redeem shares of the Portfolio must first contact the Advisor at (888) 576-1167 or (512) 306-7400. Shareholders who invest in the Portfolio through a financial intermediary should contact their financial intermediary regarding redemption procedures. The Portfolio will redeem shares at the net asset value of such shares next determined after receipt of a written request for redemption in good order, by the transfer agent (or by an Intermediary or a Subdesignee, if applicable. “Good order” means that the request to redeem shares must include all necessary documentation, to be received in writing by the Advisor no later than the close of regular trading on the NYSE (normally, 1:00 p.m. PT), including but not limited to: a letter of instruction or a stock assignment specifying the number of shares or dollar amount to be redeemed, signed by all registered owners (or representatives thereof) of the shares; and, if the Fund does not have on file the authorized signatures for the account, proof of authority.

Shareholders redeeming shares who have authorized redemption payment by wire in writing may request that redemption proceeds be paid in federal funds wired to the bank they have designated in writing. The Fund reserves the right to send redemption proceeds by check in its discretion; a shareholder may request overnight delivery of such check at the shareholder’s own expense. If the proceeds are wired to the shareholder’s account at a bank that is not a member of the Federal Reserve System, there could be a delay in crediting the funds to the shareholder’s bank account. The Fund reserves the right at any time to suspend or terminate the redemption by wire procedure after prior notification to shareholders. No fee is charged for redemptions. The redemption of all shares in an account will result in the account being closed. A new Account Registration Form will be required for future investments. See “PURCHASE OF SHARES.” In the interests of economy and convenience, certificates for shares are not issued.

Although the redemption payments will ordinarily be made within seven days after receipt, payment to investors redeeming shares that were purchased by check will not be made until the Fund can verify that the payments for the purchase have been, or will be, collected, which may take up to ten days or more. Investors may avoid this delay by submitting a certified check along with the purchase order.

Redemption of Small Accounts

The Fund reserves the right to redeem an account if the value of the shares in the Portfolio is $500 or less because of redemptions. Before the Fund involuntarily redeems shares from such an account and sends the proceeds to the stockholder, the Fund will give written notice of the redemption to the stockholder at least sixty days before the redemption date. The stockholder will then have sixty days from the date of the notice to make an additional investment in order to bring the value of the shares in the account for the Portfolio to more than $500 and avoid such involuntary redemption. The redemption price to be paid to a stockholder for shares redeemed by the Fund under this right will be the aggregate net asset value of the shares in the account at the close of business on the redemption date. The right to redeem small accounts applies to accounts established with the Fund’s transfer agent.

In-Kind Redemptions

When in the best interests of the Portfolio, the Portfolio may make a redemption payment, in whole or in part, by a distribution of portfolio securities that the Portfolio owns in lieu of cash or by a distribution of portfolio securities that the Portfolio receives from Underlying Funds in lieu of cash. Such distributions will be made in accordance with the federal securities laws and regulations governing mutual funds. Investors may incur brokerage charges and other transaction costs selling securities that were received in payment of redemptions. The Portfolio reserves the right to redeem its shares in the currencies in which its investments (or the investments of its Underlying Funds) are denominated. Investors may incur charges in converting such securities to dollars and the value of the securities may be affected by currency exchange fluctuations.

DISCLOSURE OF PORTFOLIO HOLDINGS

The Portfolio and each Underlying Fund generally will disclose up to its 25 largest portfolio holdings (other than cash and cash equivalents) and the percentages that each of these largest portfolio holdings represent of the total assets of the Portfolio or Underlying Fund, as of the most recent month-end, online at the Advisor’s public website,

http://www.dimensional.com, within 20 days after the end of each month. The Portfolio and each Underlying Fund also generally will disclose its complete portfolio holdings (other than cash and cash equivalents), as of month-end, online at the Advisor’s public website, two months following the month-end or more frequently and at different periods when authorized in accordance with the Portfolio’s and Underlying Funds’ policies and procedures. Please consult the SAI for a description of the other policies and procedures that govern disclosure of the portfolio holdings by the Portfolio and Underlying Funds.

DELIVERY OF SHAREHOLDER DOCUMENTS

To eliminate duplicate mailings and reduce expenses, the Portfolio may deliver a single copy of certain shareholder documents, such as this Prospectus and annual and semi-annual reports, to related shareholders at the same address, even if accounts are registered in different names. This practice is known as “householding.” The Portfolio will not household personal information documents, such as account statements. If you do not want the mailings of these documents to be combined with other members of your household, please call us collect at (512) 306-7400. We will begin sending individual copies of the shareholder documents to you within 30 days of receiving your request.
