RISK/RETURN SUMMARY

About the Portfolios

The Portfolios:

o Are generally offered to only to institutional investors and clients of
registered investment advisors.
o Do not charge sales commissions or "loads."
o Are designed for long-term investors.

Management

Dimensional Fund Advisors LP (the "Advisor") is the investment manager for the
Portfolios.

Equity Investment Approach

The Advisor believes that equity investing should involve a long-term view and a
focus on asset class (e.g., U.S. securities) selection, not stock picking. It
places priority on controlling expenses, portfolio turnover, and trading costs.
Many other investment managers concentrate on reacting to price movements and
choosing individual securities.

Portfolio construction: Generally, the Advisor structures a Portfolio by:

l. Selecting a starting universe of securities (for example, all publicly
traded U.S. common stocks).

2. Creating a subset of companies meeting the Advisor's investment guidelines.

3. Excluding the securities of certain companies and emphasizing the exposure
to others after analyzing various factors (for example, book-to-market
ratio, size or liquidity.

4. Purchasing securities so the Portfolio is generally diversified within its
targeted asset class, while, relative to a portfolio without environmental
impact considerations, excluding or underweighting securities of companies
that, according to the Portfolio's environmental impact considerations, may
have a relatively negative impact on the environment as compared to
companies with similar business lines and overweighting securities of
companies that may have a relatively positive impact on the environment as
compared to companies with similar business lines.

See "APPLYING THE PORTFOLIOS' ENVIRONMENTAL IMPACT CONSIDERATIONS" for a
description of the environmental impact considerations utilized by the
Portfolios.

Investment Objectives, Strategies, and Risks

U.S. Sustainability Core 1 Portfolio

o Investment Objective: Long-term capital appreciation.
o Investment Strategy: Purchase a broad portfolio of securities of U.S.
operating companies with an increased exposure to small capitalization and
value companies, while, relative to a portfolio without environmental
impact considerations, excluding or underweighting securities of companies
that, according to the Portfolio's environmental impact considerations, may
have a relatively negative impact on the environment as compared to
companies with similar business lines, and overweighting securities of
companies that may have a relatively positive impact on the environment as
compared to companies with similar business lines.
o Principal Risks: Market Risk, Small Company Risk and Environmental
Consideration Investment Risk.

International Sustainability Core 1 Portfolio

o Investment Objective: Long-term capital appreciation.
o Investment Strategy: Purchase a broad portfolio of securities of non-U.S.
companies with an increased exposure to small capitalization and value
companies, while, relative to a portfolio without environmental impact
considerations, excluding or underweighting securities of companies that,
according to the Portfolio's environmental impact considerations, may have
a relatively negative impact on the environment as compared to companies
with similar business lines, and overweighting securities of companies that
may have a relatively positive impact on the environment as compared to
companies with similar business lines.
o Principal Risks: Market Risk, Small Company Risk, Foreign Securities and
Currencies Risk and Environmental Consideration Investment Risk.

Principal Risks

Market Risk (Both Portfolios): Even a long-term investment approach cannot
guarantee a profit. Economic, political, and issuer-specific events will cause
the value of securities, and the Portfolio that owns them, to rise or fall.
Because the value of your investment in the Portfolio will fluctuate, there is
the risk that you may lose money.

Small Company Risk (Both Portfolios): Securities of small companies are often
less liquid than those of large companies. As a result, small company stocks may
fluctuate relatively more in price.

Foreign Securities and Currencies Risk (International Sustainability Core 1
Portfolio): 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 also are
exposed to foreign currency risk (the possibility that foreign currency will
fluctuate in value against the U.S. dollar).

Environmental Impact Consideration Investment Risk (Both Portfolios): A
Portfolio's environmental impact considerations may limit the number of
investment opportunities available to the Portfolio, and as a result, at times,
the Portfolio may produce more modest gains than funds that are not subject to
such special investment considerations. For example, a Portfolio may decline to
purchase, or underweight its investment in, certain securities due to
environmental impact considerations when other investment considerations would
suggest that a more significant investment in such securities would be
advantageous. In addition, a Portfolio may sell certain securities due to
environmental impact considerations when it is otherwise disadvantageous to do
so. The environmental impact considerations may cause the Portfolio's industry
allocation to deviate from that of funds without these considerations and of
conventional benchmarks.

Other Risks

Derivatives: Derivatives are securities, such as futures contracts, whose value
is derived from that of other securities or indices. Each Portfolio may use
derivatives, such as futures contracts and options on futures contracts, to gain
market exposure on the Portfolio's uninvested cash pending investment in
securities or to maintain liquidity to pay redemptions. Gains or losses from
derivative investments may be substantially greater than the derivatives'
original cost.

Securities Lending: Each Portfolio may lend its portfolio securities to generate
additional income. Securities lending involves the risk that the borrower may
fail to return the securities in a timely manner or at all. As a result, a
Portfolio may lose money and there may be a delay in recovering the loaned
securities. A Portfolio also could 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 may have certain
potential adverse tax consequences. See "SECURITIES LOANS" for further
information on securities lending.

Other Information

Commodity Pool Operator Exemption: Each Portfolio 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"), and, therefore, such person
is not subject to registration or regulation as a pool operator under the CEA.

Risk and Return Bar Chart and Table

Performance information is not available for the Portfolios because they are
new.

FEES AND EXPENSES

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

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

Net Expenses............................................................0.55%**

* "Other Expenses" are annualized expenses based on anticipated fees and
expenses payable by the Portfolio through the fiscal year ending November
30, 2008.

** Pursuant to a Fee Waiver and Expense Assumption Agreement for each
Portfolio, the Advisor has agreed to waive all or a portion of its
management fee and to assume the ordinary operating expenses of the
Portfolio (excluding the expenses that the Portfolio incurs indirectly
through its investment in other investment companies) ("Portfolio
Expenses") to the extent necessary to limit the Portfolio Expenses of the
U.S. Sustainability Core 1 Portfolio and International Sustainability Core
1 Portfolio to 0.35% and 0.55%, respectively, of each Portfolio's average
net assets on an annualized basis (the "Expense Limitation Amount"). At any
time that the Portfolio Expenses of a Portfolio are less than the
Portfolio's Expense Limitation Amount, 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
Portfolio's annualized Portfolio Expenses to exceed the Portfolio's Expense
Limitation Amount. A 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. The Fee
Waiver and Expense Assumption Agreement will remain in effect for an
initial period until April 1, 2009, and then shall continue in effect from
year to year for one-year periods thereafter unless terminated by the
Advisor.

EXAMPLE

This Example is meant to help you compare the cost of investing in the
Portfolios 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. Although your
actual costs may be higher or lower, based on these assumptions, your costs
would be as follows:

l Year 3 Years
U.S. Sustainability Core 1 Portfolio ................. $36 $115
International Sustainability Core 1 Portfolio......... $56 $176

Because the Portfolios are new, the Example for each Portfolio is based on
the anticipated expenses for the Portfolio for the current fiscal year, and does
not extend over five- and ten-year periods.

HIGHLIGHTS

Management Services

The Advisor serves as investment advisor to the Portfolios. See "MANAGEMENT
OF THE PORTFOLIOS."

Purchase, Valuation, and Redemption of Shares

The shares of each Portfolio are sold at net asset value. The redemption
price of the shares of each Portfolio is also equal to the net asset value of
its shares. The value of a Portfolio's shares will fluctuate in relation to its
own investment experience. See "PURCHASE OF SHARES," "VALUATION OF SHARES," and
"REDEMPTION OF SHARES."

Electronic Shareholder Information

In order to conserve natural resources, an investor, when opening an
account, is expected to consent to the acceptance of all shareholder information
about the Portfolios through electronic delivery and access to the Portfolios'
web site at www.dfafunds.com. See "ELECTRONIC SHAREHOLDER INFORMATION AND
TRANSACTIONS."

INVESTMENT OBJECTIVES AND POLICIES

U.S. SUSTAINABILITY CORE 1 PORTFOLIO

The investment objective of the U.S. Sustainability Core 1 Portfolio (the
"U.S. Portfolio") is to achieve long-term capital appreciation. The U.S.
Portfolio seeks to achieve its investment objective by purchasing a broad and
diverse group of common stocks of U.S. companies with an increased exposure to
small capitalization and value companies relative to the U.S. Universe, while,
relative to a portfolio without the environmental impact considerations,
excluding or underweighting securities of companies that, according to the
Portfolio's environmental impact considerations, may have a relatively negative
impact on the environment and overweighting securities of companies that may
have a relatively positive impact on the environment. (See "APPLYING THE
PORTFOLIOS' ENVIRONMENTAL IMPACT CONSIDERATIONS.") The Advisor defines the "U.S.
Universe" as a market capitalization weighted portfolio of U.S. operating
companies listed on the New York Stock Exchange ("NYSE"), American Stock
Exchange ("Amex") and Nasdaq Global Market ("Nasdaq"). The increased exposure to
small and value companies may be achieved by decreasing the allocation of the
U.S. Portfolio's assets to the largest U.S. growth companies relative to their
weight in the U.S. Universe, which would result in a greater weight allocation
to small capitalization and value companies. As of the date of this Prospectus,
the Advisor considers small capitalization companies to be companies whose
market capitalizations are in the lowest 10% of total market capitalization or
companies whose market capitalizations are smaller than the 1000th largest U.S.
company, whichever results in the higher market capitalization break. Under the
Advisor's market capitalization guidelines described above, as of October 31,
2007, the market capitalization of a small cap company was defined by the 10%
market capitalization guideline to be $2,605 million, or below. This dollar
amount will change due to market conditions. An equity issuer is considered a
growth company primarily because it has a low, non-negative book value in
relation to its market capitalization. An equity issuer is considered a value
company primarily because it has a high book value in relation to its market
capitalization. In assessing growth and value, the Advisor may consider
additional factors, such as price-to-cash-flow or price-to-earnings ratios, as
well as economic conditions and developments in the issuer's industry.

The percentage allocation of the assets of the U.S. Portfolio to securities
of the largest U.S. growth companies, as defined above, will generally be
reduced from between 2.5% and 25% of their percentage weight in the U.S.
Universe. For example, as of December 31, 2006, securities of the largest U.S.
growth companies comprised 26% of the U.S. Universe, and if the U.S. Portfolio
had been in operation, the Advisor would have allocated 7% of the U.S.
Portfolio's assets to securities of the largest U.S. growth companies. The
percentage by which the U.S. Portfolio's allocation to securities of the largest
U.S. growth companies is reduced will fluctuate with market movements.
Additionally, the range by which the U.S. Portfolio's percentage allocation to
the securities of the largest U.S. growth companies is reduced as compared to
the U.S. Universe will change from time to time and may be impacted by the
Portfolio's investment strategies with respect to environmental impact
considerations.

As a non-fundamental policy, under normal circumstances, the U.S. Portfolio
will invest at least 80% of its net assets in securities of U.S. companies. If
the U.S. Portfolio changes this investment policy, the U.S. Portfolio will
notify shareholders at least 60 days before the change, and will change the name
of the Portfolio.

The U.S. Portfolio also may invest in exchange-traded funds (ETFs) and
similarly structured pooled investments for the purpose of gaining exposure to
the U.S. stock market while maintaining liquidity. The U.S. Portfolio also may
use derivatives, such as futures contracts and options on futures contracts, to
gain market exposure on uninvested cash pending investment in securities or to
maintain liquidity to pay redemptions. The U.S. Portfolio may enter into futures
contracts and options on futures contracts for U.S. equity securities and
indices. In addition to money market instruments and short-term investments, the
U.S. Portfolio may invest in affiliated and unaffiliated registered and
unregistered money market funds to manage the Portfolio's cash pending
investment in other securities or to maintain liquidity for the payment of
redemptions or other purposes. Investments in money market funds may involve a
duplication of certain fees and expenses. The above-referenced investments are
not subject to, although they may incorporate, the U.S. Portfolio's
environmental impact considerations.

INTERNATIONAL SUSTAINABILITY CORE 1 PORTFOLIO

The investment objective of the International Sustainability Core 1
Portfolio (the "International Portfolio") is to achieve long-term capital
appreciation. The International Portfolio seeks to achieve its investment
objective by purchasing a broad and diverse group of stocks of non-U.S.
companies with an increased exposure to small capitalization and value companies
relative to the International Universe, while, relative to a portfolio without
environmental impact considerations, excluding or underweighting securities of
companies that, according to the Portfolio's environmental impact
considerations, may have a relatively negative impact on the environment and
overweighting securities of companies that may have a relatively positive impact
on the environment. (See "APPLYING THE PORTFOLIOS' ENVIRONMENTAL IMPACT
CONSIDERATIONS.") For purposes of this Portfolio, the Advisor defines the
"International Universe" as a market capitalization weighted portfolio of
non-U.S. companies in developed markets that have been authorized for investment
by the Advisor's Investment Committee. As of the date of this Prospectus, the
following markets have been authorized for investment for the Portfolio and
comprise the International Universe: Australia, Austria, Belgium, Canada,
Denmark, Finland, France, Germany, Greece, Hong Kong, Ireland, Italy, Japan, the
Netherlands, New Zealand, Norway, Portugal, Singapore, Spain, Sweden,
Switzerland and the United Kingdom (collectively, the "Authorized Markets"). The
Advisor will determine in its discretion when and whether to invest in markets
that have been authorized, depending on a number of factors, such as asset
growth in the Portfolio and characteristics of each such market. The Investment
Committee of the Advisor also may authorize other markets for investment in the
future, in addition to the Authorized Markets identified above, or may remove
one or more markets from the list of Authorized Markets.

The increased exposure to small capitalization and value companies for the
International Portfolio may be achieved by decreasing the allocation of the
Portfolio's assets to the largest growth companies relative to their weight in
the International Universe, which would result in a greater weight allocation to
small capitalization and value companies. As of October 31, 2007, on an
aggregate basis for the Portfolio, the Advisor considered small capitalization
companies to be those companies with a market capitalization below $4,355
million. This threshold will vary by country or region. An equity issuer is
considered a growth company primarily because it has a low, non-negative book
value in relation to its market capitalization. An equity issuer is considered a
value company primarily because it has a high book value in relation to its
market capitalization. In assessing growth and value, the Advisor may consider
additional factors, such as price-to-cash-flow or price-to-earnings ratios, as
well as economic conditions and developments in the issuer's industry.

The Advisor determines company size on a country- or region-specific basis
and based primarily on market capitalization. The percentage allocation of the
assets of the International Portfolio to securities of the largest growth
companies as defined above will generally be reduced from between 5% and 35% of
their percentage weight in the International Universe. For example, as of
December 31, 2006, securities of the largest growth companies in the
International Universe comprised 16% of the International Universe, and if the
International Portfolio had been in operation, the Advisor would have allocated
4% of the International Portfolio's assets to securities of the largest growth
companies in the International Universe. The percentage by which the
International Portfolio's allocation to securities of the largest growth
companies is reduced will fluctuate with market movements. Additionally, the
range by which the International Portfolio's percentage allocation to the
securities of the largest growth companies is reduced as compared to the
International Universe will change from time to time and may be impacted by the
Portfolio's investment strategies with respect to environmental impact
considerations.

The International Portfolio may invest in Exchange Traded Funds (ETFs) and
similarly structured pooled investments for the purpose of gaining exposure to
the equity markets, including the U.S. equity market, while maintaining
liquidity. The International Portfolio also may use derivatives, such as futures
contracts and options on futures contracts, to gain market exposure on
uninvested cash pending investment in securities or to maintain liquidity to pay
redemptions. The International Portfolio may enter into futures contracts and
options on futures contracts for equity securities and indices, including U.S.
issuers and indices. In addition to money market instruments and other
short-term investments, the Portfolio may invest in affiliated and unaffiliated
registered and unregistered money market funds to manage the Portfolio's cash
pending investment in other securities or to maintain liquidity for the payment
of redemptions or other purposes. Investments in money market funds may involve
a duplication of certain fees and expenses. The above-referenced investments are
not subject to, although they may incorporate, the International Portfolio's
environmental impact considerations.

The International Portfolio invests in securities of Authorized Markets (as
identified above) listed on bona fide securities exchanges or traded on the
over-the-counter markets. These exchanges or over-the-counter markets may be
either within or outside the issuer's domicile country. For example, the
securities may be listed or traded in the form of European Depositary Receipts,
Global Depositary Receipts, American Depositary Receipts, or other types of
depositary receipts (including non-voting depositary receipts) or dual listed
securities. The International Portfolio will consider for purchase securities
that are associated with an Authorized Market, and include, among others: (a)
securities of companies that are organized under the laws of, or maintain their
principal place of business in, an Authorized Market; (b) securities for which
the principal trading market is in an Authorized Market; (c) securities issued
or guaranteed by the government of an Authorized Market, its agencies or
instrumentalities, or the central bank of such country or territory; (d)
securities denominated in an Authorized Market currency issued by companies to
finance operations in Authorized Markets; (e) securities of companies that
derive at least 50% of their revenues or profits from goods produced or sold,
investments made, or services performed in Authorized Markets or have at least
50% of their assets in Authorized Markets; (f) equity securities of companies in
Authorized Markets in the form of depositary shares; (g) securities of pooled
investment vehicles that invest primarily in securities of Authorized Markets or
derivative instruments that derive their value from securities of Authorized
Markets; or (h) securities included in the Portfolio's benchmark index.
Securities of Authorized Markets may include securities of companies that have
characteristics and business relationships common to companies in other
countries or regions. As a result, the value of the securities of such companies
may reflect economic and market forces in such other countries or regions as
well as in the Authorized Markets. The Advisor, however, will select only those
companies that, in its view, have sufficiently strong exposure to economic and
market forces in Authorized Markets. For example, the Advisor may invest in
companies organized and located in the United States or other countries or
regions outside of Authorized Markets, including companies having their entire
production facilities outside of Authorized Markets, when such companies meet
the criteria discussed above to be considered associated with Authorized
Markets.

APPLYING THE PORTFOLIOS' ENVIRONMENTAL IMPACT CONSIDERATIONS

The Advisor intends to take into account the impact that companies have on
the environment when making investment decisions for a Portfolio by excluding or
underweighting, relative to a portfolio without environmental impact
considerations, securities of companies that, according to the Portfolio's
environmental impact considerations, may have a relatively negative impact on
the environment as compared to companies with similar business lines, and
overweighting, relative to a portfolio without environmental impact
considerations, securities of companies that may have a relatively positive
impact on the environment as compared to companies with similar business lines.
The Advisor is expected to engage one or more third party service providers to
provide research and ratings information relating to the Portfolio's
environmental impact considerations with respect to securities in the
portfolios, where information is available from such providers.

Examples of the types of considerations that are expected to be used to
evaluate companies' impact on the environment are as follows:

Negative Factors:

o Agricultural chemicals: The company produces substantial amounts of
agricultural chemicals, including pesticides.
o Climate change: A substantial percentage of the company's revenues relate,
directly or indirectly, to the sale of coal or oil and their derivative
fuel products.
o Hazardous waste: The company has incurred substantial liabilities, such as
significant fines or civil penalties, for hazardous waste or waste
management violations.
o Ozone depleting chemicals: The company is a manufacturer of ozone depleting
chemicals such as HCFCs, methyl chloroform, methylene, chloride, or
bromines.
o Regulatory problems: The company recently has incurred substantial fines or
civil penalties for, or demonstrated a pattern of issues regarding,
violations of air, water, or other environmental regulations.
o Substantial emissions: The company exhibits markedly high emissions of
toxic chemicals into the air and water from individual plants.
o Negative economic impact: The company's actions have incited major
controversies regarding the quality of life, or property values in the
community.
o Other environmental concerns: The company has had material involvement in
an environmental controversy not covered by other factors.

Positive Factors:

o Beneficial products and services: The company earns substantial revenues
through the development of innovative products with environmental benefits,
including remediation products, environmental services, or products that
promote the efficient use of energy.
o Clean energy: The company has taken notable steps to reduce the impact of
its operations on global climate change and air pollution through the use
of renewable energy or other clean fuels, or through the introduction of
energy efficient programs or sale of products promoting energy efficiency.
o Environmental management systems: The company has exhibited a strong
commitment to environmental management systems through ISO 14001
certification and other voluntary programs.
o Pollution prevention: The company has established strong pollution
prevention programs, including those designed to cut both emissions and
toxic uses.
o Recycling: The company either uses a significant percentage of recycled
materials in its manufacturing process, or is a major firm in the recycling
industry.
o Other strengths: The company has undertaken noteworthy environmental
initiatives not covered by other factors.

The environmental impact considerations listed above seek to identify
factors that the Advisor believes indicate whether or not a company, as compared
to other companies with similar business lines, promotes sustainability by
pursuing economic growth and development that meets the needs of the present
without compromising the needs of future generations. A Portfolio may
periodically modify its environmental impact considerations.

Based on the research and ratings information provided by the third party
service providers on a company with respect to both the positive and negative
environmental factors, the Advisor will determine an overall environmental
impact score for the company. The Advisor will use the overall environmental
impact score of a company to determine whether the securities of the company
should be: (i) excluded from a Portfolio's securities holdings; (ii)
underweighted within the Portfolio; or (iii) overweighted within the Portfolio.

As described above, the Advisor will endeavor to consider the environmental
impact of each company when constructing a Portfolio's investment portfolio.
However, the Advisor may not be able to assess the environmental impact of each
company eligible for purchase by a Portfolio. For example, the Advisor may not
be able to determine an overall environmental impact score for each company
based on the environmental considerations described above because the third
party service providers may not have data on the entire universe of companies
considered by the Advisor for a Portfolio, or may not have information with
respect to each factor listed above as an environmental impact consideration.

The environmental impact of a company may change while a Portfolio is
holding the company's securities due to actions taken by the company or new
information that becomes available concerning the company, and such information
may impact the Portfolio's decision to buy shares in the future of such company
but will not necessarily result in changes to current holdings of such shares.
For instance, if negative information about a company becomes available, while
future investment decisions should reflect that information, the Portfolio may
continue to hold the securities it already owns in the short or long term, so
that the composition of the Portfolio may not, at all times, reflect the most
current environmental impact considerations. A Portfolio's exposure to
companies, industries and sectors of the market may be affected by environmental
impact data obtained that may not be completely accurate with respect to any
company or by a given environmental factor that may not be as relevant as
assumed in the overall score.

Because the Advisor takes into account environmental impact considerations
when constructing the investment portfolio for a Portfolio, a Portfolio may not
invest in, or deviate in its exposure to, certain types of companies,
industries, and segments of the designated markets in which a similar Portfolio
without environmental impact considerations invests.

Each Portfolio's environmental impact considerations are designed to meet
the investing needs of shareholders; the exclusion, purchase, or sale of
specific securities in a Portfolio should not be construed as reflecting a
judgment by the Advisor or the Board of Directors of the Fund relating to any
environmental issue.

PORTFOLIO TRANSACTIONS

Securities will not be purchased or sold based on the prospects for the
economy, the securities markets, or the individual issuers whose shares are
eligible for purchase. Securities that have depreciated in value since their
acquisition will not be sold solely because prospects for the issuer are not
considered attractive or due to an expected or realized decline in securities
prices in general. Securities will not be sold to realize short-term profits,
but when circumstances warrant, they may be sold without regard to the length of
time held. Securities, including those eligible for purchase, may be disposed
of, however, at any time when, in the Advisor's judgment, circumstances warrant
their sale, including, but not limited to, tender offers, mergers, and similar
transactions, or bids made for block purchases at opportune prices. Generally,
securities will be purchased with the expectation that they will be held for
longer than one year and will be held until such time as they are no longer an
appropriate holding in light of the investment policies of a Portfolio.

SECURITIES LOANS

Each Portfolio is authorized to lend securities to qualified brokers,
dealers, banks, and other financial institutions for the purpose of earning
additional income. While a Portfolio may earn additional income from lending
securities, such activity is incidental to the investment objective of the
Portfolio. The value of securities loaned may not exceed 33 1/3% of the value of
a Portfolio's total assets, which includes the value of collateral received. To
the extent a Portfolio loans a portion of its securities, the Portfolio 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, a
Portfolio may invest the collateral received for the loaned securities in
securities of the U.S. government or its agencies, repurchase agreements
collateralized by securities of the U.S. government or its agencies, and
registered and unregistered money market funds. For purposes of this paragraph,
agencies include both agency debentures and agency mortgage-backed securities.
In addition, a Portfolio 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. See the Portfolios' Statement of Additional
Information (the "SAI") for a further discussion of the tax consequences related
to securities lending. A Portfolio will be entitled to recall a loaned security
to vote proxies or otherwise obtain rights to vote proxies of loaned securities
if the Portfolio knows that a material event will occur. In the event of the
bankruptcy of the borrower, the Fund could experience delay in recovering the
loaned securities or only recover cash or a security of equivalent value. See
"OTHER RISKS--SECURITIES LENDING" for a discussion of the risks related to
securities lending.

MANAGEMENT OF THE PORTFOLIOS

The Advisor serves as investment advisor to each Portfolio. As such, the
Advisor is responsible for the management of each Portfolio's assets. Each
Portfolio is managed using a team approach. The investment team includes the
Investment Committee of the Advisor, portfolio managers, and other 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 eight members. Investment strategies
for each Portfolio 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 authorized countries, security types, and
brokers.

In accordance with the team approach used to manage each Portfolio, 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 each Portfolio, including
running buy and sell programs, based on the parameters established by the
Investment Committee. Robert T. Deere, the portfolio manager for the U.S.
Portfolio, coordinates the efforts of all other portfolio managers with respect
to the day-to-day management of that Portfolio and other domestic equity
portfolios managed by the Advisor. Karen E. Umland, the portfolio manager for
the International Portfolio, coordinates the efforts of all other portfolio
managers with respect to the day-to-day management of that Portfolio and other
international equity portfolios managed by the Advisor.

Mr. Deere is a Senior Portfolio Manager and Vice President of the Advisor
and a member of the Investment Committee. Mr. Deere received his MBA from the
University of California at Los Angeles in 1991. He also holds a BS and BA from
the University of California at San Diego. Mr. Deere joined the Advisor in 1991
and has been responsible for the domestic equity portfolios since 1994.

Ms. Umland is a Senior Portfolio Manager and Vice President of the Advisor
and a member of the Investment Committee. She received her BA from Yale
University in 1988 and her MBA from the University of California at Los Angeles
in 1993. Ms. Umland joined the Advisor in 1993 and has been responsible for the
international equity portfolios since 1998.

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

The Advisor provides each Portfolio 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 1299 Ocean Avenue, Santa Monica, CA 90401. A discussion regarding the
basis for the Board of Directors' approving the investment management agreements
with respect to the Portfolios will be available in future annual or semi-annual
reports to shareholders of the Portfolios.

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, 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. Expenses allocable to a particular portfolio of the Fund are so allocated.
The expenses of the Fund that are not allocable to a particular portfolio are
borne by each portfolio on the basis of its relative net assets or equally.

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. Prior to November 3,
2006, the Advisor was named Dimensional Fund Advisors Inc. and was organized as
a Delaware corporation. As of the date of this Prospectus, assets under
management total approximately $155 billion. The Advisor controls Dimensional
Fund Advisors Ltd. ("DFAL") and DFA Australia Limited ("DFA Australia").

Investment Services-International Portfolio

The Advisor has entered into a Sub Advisory Agreement with each of DFAL (7
Down Street, London W1J7AJ, United Kingdom) and DFA Australia (Level 29 Gateway
1, MacQuarie Place, Sydney, New South Wales 2000, Australia), respectively, with
respect to the International Portfolio. Pursuant to the terms of each Sub
Advisory Agreement, DFAL and DFA Australia each have the authority and
responsibility to select brokers and dealers to execute securities transactions
for the International Portfolio. Each Sub Advisor's duties include the
maintenance of a trading desk and the determination of the best and most
efficient means of executing securities transactions. On at least a semi-annual
basis, the Advisor will review the holdings of the International Portfolio and
review the trading process and the execution of securities transactions. The
Advisor is responsible for determining those securities that are eligible for
purchase and sale by the International Portfolio and may delegate this task,
subject to its own review, to DFAL and DFA Australia. DFAL and DFA Australia
maintain and furnish to the Advisor information and reports on small companies
in certain markets, including recommendations of securities to be added to the
securities that are eligible for purchase by the International Portfolio, as
well as making recommendations and elections on corporate actions. DFAL is a
member of the Financial Services Authority ("FSA"), a self-regulatory
organization for investment managers operating under the laws of England.

DIVIDENDS, CAPITAL GAINS DISTRIBUTIONS AND TAXES

Dividends and Distributions

Each Portfolio intends to qualify each year as a regulated investment
company under the Internal Revenue Code (the "Code"). As a regulated investment
company, a Portfolio generally pays no federal income tax on the income and
gains it distributes to shareholders. Dividends from net investment income of
each Portfolio are distributed quarterly (on a calendar basis) and any net
realized capital gains (after any reductions for capital loss carry-forwards)
are distributed annually, typically in December. Each Portfolio also may make an
additional dividend distribution from net investment income in November of each
year. The amount of any distribution will vary, and there is no guarantee either
Portfolio will pay either an income dividend or a capital gains distribution.

Shareholders of each Portfolio will automatically receive all income
dividends and capital gains distributions in additional shares of the Portfolio
whose shares they 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, the shareholder selects 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.

Every January, each shareholder will receive a statement that shows the tax
status of dividends and distributions 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.

If a taxable shareholder invests in a Portfolio shortly before the record
date of a taxable distribution, the distribution will lower the value of the
Portfolio's shares by the amount of the distribution and, in effect, the
shareholder will receive some of the shareholder's investment back in the form
of a taxable distribution.

Taxes

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 portion of income dividends designated by
a Portfolio may be qualified dividend income eligible for taxation by individual
shareholders at long-term capital gains rates provided certain holding period
requirements are met.

The International Portfolio may be subject to foreign withholding taxes on
income from foreign securities. If more than 50% in value of the total assets of
the International Portfolio is invested in securities of foreign corporations,
the Portfolio may elect to pass through to its shareholders their pro rata share
of foreign income taxes paid by the Portfolio. If this election is made,
shareholders will be required to include in their gross income their pro rata
share of these foreign taxes paid by the Portfolio, and will be entitled to
deduct (as an itemized deduction in the case of individuals) their share of such
foreign taxes in computing their taxable income or to claim a credit for such
taxes against their U.S. federal income tax, subject to certain limitations
under the Code.

The sale of shares of a Portfolio is a taxable event and may result in a
capital gain or loss to shareholders who are subject to tax. Capital gains or
loss may be realized from an ordinary redemption of shares or an exchange of
shares between two Portfolios. Any loss incurred on sale or exchange of a
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.

By law, a Portfolio is required to withhold 28% of taxable dividends,
capital gains distributions, and redemption proceeds paid to shareholders who do
not provide their proper taxpayer identification number and certain required
certifications. Shareholders may avoid this withholding requirement by providing
and certifying on the account registration form their correct Taxpayer
Identification Number and by certifying that they are not subject to backup
withholding and are U.S. persons (including U.S. resident aliens). A Portfolio
must also withhold if the IRS instructs it to do so.

In addition to federal taxes, shareholders may be subject to state and
local taxes on distributions from a Portfolio and on gains arising on redemption
or exchange of a 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.

Non-U.S. investors are subject to U.S. withholding tax at a 30% or lower
treaty rate on dividends paid by a Portfolio, subject to limited exemptions for
dividends designated as capital gain dividends, short-term capital gain
dividends and interest-related dividends. The exemptions from withholding for
short-term capital gain dividends and interest-related dividends sunset and will
no longer apply to dividends paid with respect to taxable years of a Portfolio
beginning after December 31, 2007 unless such exemptions are extended or made
permanent. Notwithstanding such exemptions, non-U.S. investors are subject to
backup withholding at a rate of 28% on dividends, capital gains distributions,
and redemption proceeds paid to shareholders who fails to properly certify they
are not U.S. persons. Non-U.S. investors also may be subject to U.S. estate tax.

Income received by a Portfolio from certain equity interests in mortgage
pooling vehicles is treated as "excess inclusion income." A Portfolio may derive
such income either as a result of its direct investment in such interests or,
indirectly, through its investment in REITs that hold such interests or
otherwise qualify as taxable mortgage pools. In general, this income is required
to be reported to Portfolio shareholders that are not disqualified organizations
(as defined below) in proportion to dividends paid with the same consequences as
if the shareholders directly received the excess inclusion income. Excess
inclusion income: (i) may not be offset with net operating losses; (ii)
represents unrelated business taxable income (UBTI) in the hands of a tax-exempt
shareholder that is not a disqualified organization; and (iii) is subject to
withholding tax, without regard to otherwise applicable exemptions or rate
reductions, to the extent such income is allocable to a shareholder who is not a
U.S. person. A Portfolio must pay the tax on its excess inclusion income that is
allocable to "disqualified organizations," which generally are certain
cooperatives, governmental entities and tax-exempt organizations that are not
subject to tax on UBTI. To the extent that Portfolio shares owned by a
disqualified organization are held in record name by a broker/dealer or other
nominee, a Portfolio must inform the broker/dealer or other nominee of the
excess inclusion income allocable to them and the broker/dealer or other nominee
must pay the tax on the portion of a Portfolio's excess inclusion income
allocable to them on behalf of the disqualified organizations.

This discussion of "Dividends, Capital Gains Distributions and Taxes" is
not intended or written to be used as tax advice. Prospective investors should
consult the SAI. Because everyone's tax situation is unique, you should also
consult your tax professional about federal, state, local or foreign tax
consequences before making an investment in a Portfolio.

ELECTRONIC SHAREHOLDER INFORMATION AND TRANSACTIONS

In order to conserve natural resources, which the Advisor understands is an
important consideration of the shareholders of the Portfolios, the Portfolios
have adopted a policy that reflects such concerns, where possible, such that a
shareholder, when opening an account, is encouraged to consent to the acceptance
of all shareholder information about the Portfolio(s) in which the shareholder
invests, through electronic delivery and access to the Portfolios' web site.

The Portfolios may deliver paper-based shareholder information in certain
circumstances at no extra cost to the investor. If a shareholder calls or
e-mails the Portfolios to request paper-based shareholder information, or
revokes consent to receive all shareholder information electronically, the
Portfolios will deliver such information and the shareholder may be charged a
fee of up to $15 to cover the costs of printing, shipping and handling.
Shareholder information includes prospectuses, statements of additional
information, annual and semi-annual reports, confirmations and statements.

The Portfolios' web site address is www.dfafunds.com. The current
Prospectus of the Portfolios will be readily available for viewing and printing
on the web site.

An interruption in transmissions over the Internet generally or a problem
in the transmission of the Portfolios' web site in particular could result in a
delay or interruption in the ability of shareholders to access the web site or
otherwise interact with the Portfolios.

PURCHASE OF SHARES

Cash Purchases

Investors may purchase shares of a Portfolio by first contacting the
Advisor at (310) 395-8005 to notify the Advisor of the proposed investment. The
Portfolios generally are available for investment only by institutional clients,
clients of registered investment advisors, clients of financial institutions,
and a limited number of certain other investors, 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 by 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 a
Portfolio.

"Good order" with respect to the purchases 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 1:00 p.m. PT) on the day of the purchase.
If an order to purchase shares must be cancelled 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 cancelled, 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 (310) 395-8005 to notify the Advisor of the proposed investment,
then requesting the bank to transmit immediately available funds (federal funds)
by wire to PNC Bank, N.A. for the account of DFA Investment Dimensions Group
Inc. (specify Portfolio). Additional investments also may be made through the
wire procedure by first notifying the Advisor. Investors who wish to purchase
shares of a Portfolio by check should send their check to DFA Investment
Dimensions Group Inc., c/o PFPC Inc., P.O. Box 8916, Wilmington, Delaware
19899-8916.

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 a Portfolio may be purchased in exchange
for securities that are eligible for acquisition by the Portfolio or otherwise
represented in its portfolio as described in this Prospectus or in exchange for
local currencies in which such securities of the International Portfolio are
denominated. Securities and local currencies accepted by the Fund for exchange
and Portfolio 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, interests, 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 a Portfolio with local currencies should first contact the Advisor for wire
instructions.

The Fund will not accept securities in exchange for shares of a 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. The Fund will accept such securities for investment and
not for resale.

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

In addition, the International Portfolio may be more susceptible to the
risks of short-term trading than other Portfolios. The nature of the holdings of
the International Portfolio may present opportunities for a shareholder to
engage in a short-term trading strategy that exploits possible delays between
changes in the price of the Portfolio's holdings and the reflection of those
changes in the Portfolio's net asset value (called "arbitrage market timing").
Such delays may occur because the International Portfolio has significant
investments in foreign securities where, due to time zone differences, the
values of those securities are established some time before the Portfolio
calculates its net asset value. In such circumstances, the available market
prices for such foreign securities may not accurately reflect the latest
indications of value at the time the International Portfolio calculates its net
asset value. There is a possibility that arbitrage market timing may dilute the
value of the International Portfolio's shares if redeeming shareholders receive
proceeds (and purchasing shareholders receive shares) based upon a net asset
value that does not reflect appropriate fair value prices.

The Board of Directors of the Fund (the "Board") has adopted a policy (the
"Trading Policy") and the Advisor and DFA Securities Inc. (collectively,
"Dimensional") and their agents have implemented the following procedures, which
are designed to discourage and prevent market timing or excessive short-term
trading in the Portfolios: (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 Portfolios 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
Portfolios, 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 $5,000; (ii) purchases
and redemptions by U.S. registered investment companies that operate as funds of
funds pursuant to Section 12(d)(1)(G) of the 1940 Act or an SEC exemptive order,
and non-U.S. investment companies that operate as funds of funds (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 a 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 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 a Portfolio (or other portfolios 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 (and other portfolios of the Fund) by a shareholder that
has been identified as having engaged in excessive or short-term transactions in
a 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.

The purchase blocking procedures of the Trading Policy may not apply to
redemptions by shareholders whose shares are held on the books of Intermediaries
if the Intermediaries have not adopted procedures to implement this Policy. The
Fund and Dimensional will work with Intermediaries to develop such policies to
institute the 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 Portfolios 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 is severely limited 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 on or after compliance with Rule 22c-2 under the 1940 Act is
required of Intermediaries.

In addition, the purchase blocking procedures will not apply to a
redemption transaction in which a Portfolio distributes portfolio securities to
a shareholder in-kind, where the redemption will not disrupt the efficient
portfolio management of the Portfolio and the redemption is consistent with the
interests of the remaining shareholders of the Portfolio.

In addition to monitoring trade activity, the Board has adopted fair value
pricing procedures that govern the pricing of the securities of the Portfolios.
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 Portfolios' 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.

VALUATION OF SHARES

Net Asset Value

The net asset value per share of a Portfolio is calculated after the close
of the NYSE (normally, 1:00 p.m. PT) by dividing the total value of the
Portfolio's investments and other assets, less any liabilities, by the total
outstanding shares of the stock of the Portfolio. A Portfolio generally
calculates its net asset value per share and accepts 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 1:00 p.m. PT.

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

Securities held by a Portfolio (including over-the-counter securities) are
valued at the last quoted sale price of the day. Securities held by a Portfolio
that are listed on Nasdaq are valued at the Nasdaq Official Closing Price
("NOCP"). If there is no last reported sales price or NOCP of the day, a
Portfolio values the securities at the mean between the most recent quoted bid
and asked prices. Price information on listed securities is taken from the
exchange where the security is primarily traded. Generally, securities issued by
open-end investment companies 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 a Portfolio 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 the Fund.
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 a Portfolio may
differ from the quoted or published prices for the same securities on their
primary markets or exchanges.

As of the date of this Prospectus, the International Portfolio will also
fair value price in the circumstances described below. Generally, trading in
foreign securities markets is completed each day at various times before the
close of the NYSE. For example, trading in the Japanese securities markets is
completed each day at the close of the Tokyo Stock Exchange (normally, 11:00
p.m. PT), which is fourteen hours before the close of the NYSE (normally, 1:00
p.m. PT) and the time that the net asset values of the International Portfolio
is computed. Due to the time differences between the closings of the relevant
foreign securities exchanges and the time the International Portfolio prices its
shares at the close of the NYSE, the International Portfolio will fair value its
foreign investments when it is determined that the market quotations for the
foreign investments are either unreliable or not readily available. The fair
value prices will attempt to reflect the impact of the U.S. financial markets'
perceptions and trading activities on the International Portfolio's foreign
investments since the last closing prices of the foreign investments were
calculated on their primary foreign securities markets or exchanges. For these
purposes, the Board of Directors of the Fund has determined that movements in
relevant indices or other appropriate market indicators, after the close of the
Tokyo Stock Exchange or the London Stock Exchange, demonstrate that market
quotations may be unreliable, and may trigger fair value pricing. Consequently,
fair valuation of portfolio securities may occur on a daily basis. The fair
value pricing by the International Portfolio utilizes data furnished by an
independent pricing service (and that data draws upon, among other information,
the market values of foreign investments). The fair value prices of portfolio
securities generally will be used when it is determined that the use of such
prices will have a material impact on the net asset value of the International
Portfolio. When the International Portfolio uses fair value pricing, the values
assigned to the International Portfolio's foreign investments may not be the
quoted or published prices of the investments on their primary markets or
exchanges. The Board of Directors of the Fund monitors the operation of the
method used to fair value price the International Portfolio's foreign
investments.

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 a Portfolio could obtain the fair value assigned to a security
if it were to sell the security at approximately the time at which the Portfolio
determines its net asset value per share. As a result, the sale or redemption by
a Portfolio 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 value per share of the International Portfolio is expressed
in U.S. dollars by translating the net assets of the Portfolio using the mean of
the most recent bid and asked prices for the dollar as quoted by generally
recognized reliable sources. Since the International Portfolio owns securities
that are primarily listed on foreign exchanges that may trade on days when the
Portfolio does not price its shares, the net asset value of the Portfolio 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 a Portfolio 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 a Portfolio 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 appoint,
from time to time, 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 ("Sub-designees") to receive purchase
and redemption orders for a Portfolio's shares from investors. With respect to
such investors, the shares of a Portfolio will be priced at the public offering
price calculated after receipt of the purchase order by the Intermediary or
Sub-designee, as applicable, that is authorized to receive purchase orders. If
the investor buys shares through an Intermediary or Sub-designee, the purchase
price will be the public offering price next calculated after the Intermediary
or Sub-designee, as applicable, receives the order, rather than on the day the
custodian receives the investor's payment (provided that the Intermediary or
Sub-designee, as applicable, has received the investor's purchase order in good
order, and the investor has complied with the Intermediary's or Sub-designee's
payment procedures). No reimbursement fee or sales charge is imposed on
purchases.

EXCHANGE OF SHARES

Investors may exchange shares of a Portfolio for shares of another
portfolio by first contacting the Advisor at (310) 395-8005 to notify the
Advisor of the proposed exchange and then completing a letter of instruction and
mailing it to: DFA Investment Dimensions Group Inc. as follows:

Attn: Client Operations
1299 Ocean Avenue
Santa Monica, CA 90401

The minimum amount for an exchange is $100,000. Contact the Advisor for
information regarding the portfolios available for exchanges and to request a
copy of the prospectus(es) of such portfolios. 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 loss on the
transaction. The Fund reserves the right to revise or terminate the exchange
privilege, limit the amount of or reject any exchange, or waive the minimum
amount requirement as deemed necessary, at any time.

Investors in a Portfolio also may exchange all or part of their Portfolio
shares into certain portfolios of Dimensional Investment Group Inc., subject to
the minimum purchase requirement set forth in the applicable portfolio's
prospectus. Investors may contact the Advisor at the above-listed phone number
for more information on such exchanges and to request a copy of the prospectuses
of portfolios of Dimensional Investment Group Inc.

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 a Portfolio or otherwise adversely affect the Fund, any proposed
exchange is 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 of the shares; and if the Fund does not have on
file the authorized signatures for the account, proof of authority and a
guarantee of the signature of each registered owner by an "eligible guarantor
institution." Such institutions generally include national or state banks,
savings associations, savings and loan associations, trust companies, savings
banks, credit unions, and members of a recognized stock exchange. 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 a Portfolio must first contact the
Advisor at (310) 395-8005. A 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 Sub-designee,
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 authorized representatives thereof) of the shares; and if
the Fund does not have on file the authorized signatures for the account, proof
of authority and a guarantee of the signature of each registered owner by an
eligible guarantor institution; and any other required supporting legal
documents. A signature guarantee may be obtained from a domestic bank or trust
company, broker, dealer, clearing agency or savings association who are
participants in a medallion program recognized by the Securities Transfer
Association. The three recognized medallion programs are Securities Transfer
Agents Medallion Program (STAMP), Stock Exchanges Medallion Program (SEMP), and
New York Stock Exchange, Inc. Medallion Signature Program (MSP). Signature
guarantees that are not a part of these programs will not be accepted.

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

With respect to the Portfolios, the Fund reserves the right to redeem a
shareholder's account if the value of the shares in a Portfolio is $500 or less
because of redemptions by the shareholder. Before the Fund involuntarily redeems
shares from such an account and sends the proceeds to the shareholder, the Fund
will give written notice of the redemption to the shareholder at least sixty
days before the redemption date. The shareholder 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 shareholder
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.

In-Kind Redemptions

When in the best interests of a Portfolio, it may make a redemption
payment, in whole or in part, by a distribution of portfolio securities in lieu
of cash. Such distributions will be made in accordance with the federal
securities laws and regulations governing mutual funds. A Portfolio also
reserves the right to redeem its shares in the currencies in which its
investments are denominated. Investors may incur brokerage charges and other
transaction costs in selling such securities and converting such currencies to
dollars. Also, the value of foreign securities or currencies may be affected by
currency exchange fluctuations.

DISCLOSURE OF PORTFOLIO HOLDINGS

Each Portfolio 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,
as of the most recent month-end, online at the Advisor's public web site,
http://www.dfaus.com, within 20 days after the end of each month. Each Portfolio
also generally will disclose its complete portfolio holdings (other than cash
and cash equivalents), as of month-end, online at the Advisor's public web site,
three months following the month-end. Please consult the SAI for a description
of the other policies and procedures that govern disclosure of the portfolio
holdings by the Portfolios.

DELIVERY OF SHAREHOLDER DOCUMENTS

To eliminate duplicate mailings and reduce expenses, the Portfolios 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 Portfolios will not household personal information
documents, such as account statements. If you do not want the mailings of these
documents to be combined with those of other members of your household, please
call us collect at (310) 395-8005. We will begin sending individual copies of
the shareholder documents to you within 30 days of receiving your request.

RISK/RETURN SUMMARY

About the Portfolio

The Portfolio:

o Is generally offered to institutional investors and clients of
registered investment advisors.
o Does not charge sales commissions or "loads."
o Is designed for long-term investors.

Management

Dimensional Fund Advisors LP (the "Advisor") is the investment manager for the
Portfolio.

Fixed Income Investment Approach:

Portfolio construction: Generally, the Advisor structures the Portfolio by:

1. Setting a maturity range.
2. Implementing the Advisor's quality and eligibility guidelines.
3. Purchasing securities with a view to maximizing returns.

Investment Objective, Strategies and Risks

o Investment Objective: Maximize total returns within the universe of
domestic and foreign debt securities that the Portfolio invests.
o Investment Strategy: Seek to maximize total returns from a universe of U.S.
and foreign debt securities maturing in two years or less. These debt
securities may include U.S. government securities, high-quality U.S.
corporate securities and fixed income instruments of foreign governments,
foreign corporations and supranational organizations (e.g., the World
Bank). The Portfolio also plans to invest significantly in the obligations
of the banking industry if particular conditions occur. The Portfolio may
selectively hedge its foreign currency risks depending on market
conditions.
o Principal Risks: Market Risk, Foreign Securities and Currencies Risks,
Interest Rate Risk, Credit Risk, Risk of Banking Concentration and Income
Risk.

Principal Risks

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 Portfolio, which owns the securities, to rise or fall.
Because the value of your investment in the Portfolio will fluctuate, there is
the risk that you may lose money.

Foreign Securities and Currencies Risks: 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 also are exposed to foreign currency risk (the
possibility that foreign currency will fluctuate in value against the U.S.
dollar). The Portfolio may hedge the currency exposure of its foreign securities
or leave some or all of the currency exposure unhedged.

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 securities
prices fall. When interest rates fall, fixed income securities prices rise. In
general, fixed income securities with longer maturities are more sensitive to
these price changes.

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.
Credit risk is greater for fixed income securities with ratings below investment
grade (BB or below by Standard & Poor's Ratings Group ("S&P") or Ba or below by
Moody's Investors Service, Inc. ("Moody's")). Fixed income securities that are
below investment grade involve high credit risk and are considered speculative.
Below investment grade fixed income securities also may fluctuate in value more
than higher quality fixed income securities and, during periods of market
volatility, may be more difficult to sell at the time and price the Portfolio
desires. While securities directly issued or guaranteed by the U.S. Treasury and
by agencies and instrumentalities that are backed by the full faith and credit
of the U.S. government present little credit risk, securities issued or
guaranteed by other agencies or instrumentalities may have greater credit risks.
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 Banking Concentration: 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 ("NYSE") is open for trading. Focus on the banking
industry would link the performance of the Portfolio to changes in the
performance of the banking industry generally. For example, a change in the
market's perception of the riskiness of banks compared to non-banks would cause
the value of the Portfolio's securities to fluctuate.

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

Other Risks

Derivatives:

Derivatives are securities, such as futures contracts, whose values are derived
from the values of other securities or indices. Derivatives can be used for
hedging (attempting to reduce risk by offsetting one investment position with
another) or non-hedging purposes. The Portfolio may use foreign currency
contracts to hedge foreign currency risks. Hedging with derivatives may increase
expenses, and there is no guarantee that a hedging strategy will work. While
hedging can reduce or eliminate losses, it also can reduce or eliminate gains.

The Portfolio also may use derivatives to gain market exposure on the
Portfolio's uninvested cash pending investment in securities or to maintain
liquidity to pay redemptions. The use of derivatives for non-hedging purposes
may be considered more speculative than other types of investments. When the
Portfolio uses derivatives for non-hedging purposes, the Portfolio will be
directly exposed to the risks of those derivatives. Gains or losses from
derivative instruments may be substantially greater than the derivatives'
original cost.

Securities Lending:

The Portfolio may lend its portfolio securities to generate additional income.
Securities lending involves the risk that the borrower may fail to return the
securities in a timely manner or at all. As a result, the Portfolio may lose
money and there may be a delay in recovering the loaned securities. The
Portfolio also could lose money if the Portfolio does not recover the securities
and/or the value of the collateral falls, including the value of investments
made with cash collateral. Securities lending may have certain potential adverse
tax consequences. See "SECURITIES LOANS" for further information on securities
lending.

Other Information

Commodity Pool Operator Exemption:

The Portfolio 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"), and, therefore, such person is not subject to registration or
regulation as a commodity pool operator under the CEA.

Portfolio Turnover:

The Portfolio is expected to have a high portfolio turnover rate. The rate of
portfolio turnover will depend upon market and other conditions; it will not be
a limiting factor when management believes that portfolio changes are
appropriate. While the Portfolio acquires securities in principal transactions
and, therefore, does not pay brokerage commissions, the spread between the bid
and asked prices of a security may be considered to be a "cost" of trading. Such
costs ordinarily increase with trading activity. However, securities ordinarily
will be sold when, in the Advisor's judgment, the monthly return of the
Portfolio will be increased as a result of portfolio transactions after taking
into account the cost of trading. It is anticipated that short-term instruments
will be acquired in the primary and secondary markets.

Risk and Return Bar Chart and Table

Performance information is not available for the Portfolio because it is new.

FEES AND EXPENSES

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

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

ANNUAL FUND OPERATING EXPENSES
(expenses that are deducted from Portfolio assets)

Management Fee..........................................................0.15%
Other Expenses..........................................................0.58%*

Total Annual Operating Expenses.........................................0.73%
Fee Waiver and/or Expense Reimbursements................................0.48%

Net Expenses............................................................0.25%**
__________________

* "Other Expenses" are annualized expenses based on anticipated fees and
expenses payable by the Portfolio through the fiscal year ending November
30, 2008.

** Pursuant to a Fee Waiver and Expense Assumption Agreement for the
Portfolio, the Advisor has agreed to waive all or a portion of its
management fee and to assume the ordinary operating expenses of the
Portfolio (excluding the expenses that the Portfolio incurs indirectly
through its investment in other investment companies) ("Portfolio
Expenses") to the extent necessary to limit the Portfolio Expenses of the
Portfolio to 0.25% of the Portfolio's average net assets on an annualized
basis (the "Expense Limitation Amount"). At any time that the Portfolio
Expenses of the Portfolio are less than the Portfolio's Expense Limitation
Amount, 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 Portfolio's annualized Portfolio
Expenses 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. The Fee Waiver and Expense Assumption Agreement
will remain in effect for an initial period until April 1, 2009, and then
shall continue in effect from year to year for one-year periods thereafter
unless terminated by the Advisor.

EXAMPLE

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

l Year 3 Years
DFA Selectively Hedged Global Fixed Income Portfolio......... $26 $185

Because the Portfolio is new, the Example is based on the anticipated
expenses for the Portfolio for the current fiscal year, and does not extend over
five- and ten-year periods.

HIGHLIGHTS

Management Services

The Advisor serves as investment advisor to the Portfolio. See "MANAGEMENT
OF THE PORTFOLIO."

Purchase, Valuation, and Redemption of Shares

The shares of the Portfolio are sold at net asset value. The redemption
price of the shares of the Portfolio is also equal to the net asset value of its
shares. The value of the Portfolio's shares will fluctuate in relation to its
own investment experience. See "PURCHASE OF SHARES," "VALUATION OF SHARES," and
"REDEMPTION OF SHARES."

INVESTMENT OBJECTIVE AND POLICIES

The investment objective of the Portfolio is to maximize total returns
within the universe of domestic and foreign debt securities that the Portfolio
invests. The Portfolio seeks to achieve its investment objective by investing in
a universe of U.S. and foreign debt securities. These debt securities may
include 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 having quality ratings meeting the minimum
standards described in "Description of Investments" of this Prospectus,
securities of domestic or foreign issuers denominated in U.S. dollars but not
trading in the United States, and obligations of supranational organizations,
such as the World Bank, the European Investment Bank, European Economic
Community and European Coal and Steel Community. At the present time, the
Advisor expects that most investments will be made in the obligations of issuers
that are located in developed countries, such as those countries which are
members of the Organization of Economic Cooperation and Development ("OECD").
However, in the future, the Advisor anticipates investing in issuers located in
other countries as well. Under normal market conditions, the Portfolio intends
to invest its assets in issuers organized or having a majority of their assets
in, or deriving a majority of their operating income in, at least three
different countries, one of which may be the United States.

As a non-fundamental policy, under normal circumstances, the Portfolio will
invest at least 80% of its net assets in fixed income securities. If the
Portfolio changes this investment policy, it will notify shareholders at least
60 days before the change, and will change the name of the Portfolio. It is the
policy of the Portfolio that the weighted average length of maturity of its
investments will not exceed two years. However, investments may be made in
obligations maturing in a shorter time period (from overnight, to up to two
years from the date of settlement).

Because many of the Portfolio's investments may be denominated in foreign
currencies, the Portfolio may hedge the currency exposure of the foreign
securities by entering into foreign forward currency contracts, or leave some or
all of the currency exposure unhedged. The decision to hedge the Portfolio's
currency exposure with respect to a foreign market will be based on, among other
things, a comparison of the respective foreign and U.S. short-term interest
rates and the Portfolio's existing exposure to a given foreign currency. The
Portfolio may concentrate its investments in obligations of U.S. and foreign
banks and bank holding companies (see "Investment in the Banking Industry").

Description of Investments

The following is a description of the categories of investments that may be
acquired by the Portfolio:

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 by S&P 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. 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) and bankers'
acceptances. Bank certificates of deposit will only be acquired 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, if unrated, issued by a corporation having an
outstanding unsecured debt issue rated Aaa by Moody's or AAA by S&P.

6. Repurchase Agreements--Instruments through which the Portfolio
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. The Portfolio 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 the Portfolio's total assets would be so invested. The
Portfolio also will only 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 Coal and Steel Community,
the European Economic Community and the World Bank, which are chartered to
promote economic development.

9. Foreign Issuer Obligations--Debt securities of non-U.S. issuers
rated AA or better by S&P or Aa2 or better by Moody's.

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

11. Money Market Funds--The Portfolio may invest in affiliated
and unaffiliated registered and unregistered money market funds.
Investments in money market funds may involve a duplication of certain fees and
expenses.

The categories of investments that may be acquired by the Portfolio 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.

Investments in the Banking Industry

The Portfolio will invest more than 25% of its total 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 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 investments in
banking industry securities exceed 25% of the Portfolio's total net assets, the
Portfolio will be considered to be concentrating its investments in the banking
industry. Once the Portfolio concentrates its investments in the banking
industry, the Portfolio may continue to concentrate in the banking industry
until the purchase of new investments, in the normal course of executing the
Portfolio's investment strategy, results in less than 25% of the Portfolio's
total net assets consisting of banking industry securities.

The types of bank and bank holding company obligations in which the
Portfolio may invest include: certificates of deposit, bankers' acceptances,
commercial paper and other debt obligations that mature within two years of the
date of settlement, provided such obligations meet the Portfolio's established
credit rating criteria as stated under "Description of Investments." In
addition, the Portfolio is authorized to invest more than 25% of its total
assets in U.S. Treasury bonds, bills and notes and obligations of federal
agencies and instrumentalities.

Portfolio Strategy

The Portfolio will be managed with a view to capturing credit risk premiums
and term or maturity premiums. The term "credit risk premium" means the
anticipated 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 anticipated incremental return on investment
for holding securities having maturities of longer than one month compared to
securities having a maturity of one month. The Advisor believes that credit risk
premiums are available largely through investment in high-grade commercial
paper, certificates of deposit and corporate obligations. The holding period for
assets of the Portfolio will be chosen with a view to maximizing anticipated
returns, net of trading costs.

SECURITIES LOANS

The Portfolio is authorized to lend securities to qualified brokers,
dealers, banks, and other financial institutions for the purpose of earning
additional income. While the Portfolio may earn additional income from lending
securities, such activity is incidental to the investment objective of the
Portfolio. The value of securities loaned may not exceed 33 1/3% of the value of
the Portfolio's total assets, which includes the value of collateral received.
To the extent the Portfolio loans a portion of its securities, the Portfolio
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 may invest the collateral received for the loaned securities in
securities of the U.S. government or its agencies, repurchase agreements
collateralized by securities of the U.S. government or its agencies, and
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 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. See the Portfolio's Statement of Additional
Information (the "SAI") for a further discussion of the tax consequences related
to securities lending. The Portfolio will be entitled to recall a loaned
security to vote proxies or otherwise obtain rights to vote proxies of loaned
securities if the Portfolio knows a material event will occur. In the event of
the bankruptcy of the borrower, the Portfolio could experience delay in
recovering the loaned securities or only recover cash or a security of
equivalent value. See "OTHER RISKS--SECURITIES LENDING" for a discussion of the
risks related to securities lending.

MANAGEMENT OF THE PORTFOLIO

The Advisor serves as investment advisor to the Portfolio. As such, the
Advisor is responsible for the management of the Portfolio's assets. The
Portfolio is managed using a team approach. The investment team includes the
Investment Committee of the Advisor, portfolio managers, and all other 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 eight members. Investment strategies
for the Portfolio 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 Portfolio, 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 Portfolio, including
running buy and sell programs, based on the parameters established by the
Investment Committee. David A. Plecha, the portfolio manager for the Portfolio,
coordinates the efforts of all other portfolio managers with respect to the
day-to-day management of the Portfolio and other fixed income portfolios managed
by the Advisor.

Mr. Plecha is a 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 responsible for the fixed
income portfolios managed by the Advisor since the end of 1991. The Portfolio's
SAI provides information about Mr. Plecha's compensation, other accounts managed
by Mr. Plecha, and Mr. Plecha's ownership of Portfolio shares.

The Advisor provides the Portfolio 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.

DFA Investment Dimensions Group Inc. (the "Fund") bears all of its own
costs and expenses, including: services of its independent registered public
accounting firm, legal counsel, brokerage 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, the cost of filing its registration statements under 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. Expenses allocable to a particular
portfolio of the Fund, such as the Portfolio, are so allocated. The expenses of
the Fund that are not allocable to a particular portfolio are borne by each
portfolio on the basis of its relative net assets.

A discussion regarding the basis for the Board of Directors (the "Board")
of the Fund approving the investment management agreement with respect to the
Portfolio will be available in future annual or semi-annual reports to
shareholders of the Portfolio.

own review, to DFA Australia. DFA Australia maintains and furnishes to the
Advisor information and reports on Japanese and Asia Pacific Rim fixed income
securities, 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, 7 Down Street,
London, W1J7AJ, United Kingdom, a company that is organized under the laws of
England, has the authority and responsibility to select brokers or dealers to
execute securities transactions for the Portfolio. DFAL's duties 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 by
DFAL. The Advisor is responsible for determining those securities that 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 fixed income securities,
including DFAL's recommendations of securities to be added to the securities

Financial Services Authority ("FSA"), a self-regulatory organization for
investment managers operating under the laws of England.

DIVIDENDS, CAPITAL GAINS DISTRIBUTIONS AND TAXES

Dividends and Distributions

Net investment income of the Portfolio, which is accrued daily, will be
distributed quarterly and any net realized capital gains are distributed
annually after the end of the fiscal year. The Portfolio also may make an
additional dividend distribution from net investment income in November of each
year.

Shareholders of the Portfolio will automatically receive all income
dividends and capital gains distributions in additional shares of the Portfolio
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, the shareholder selects 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.

Every January, each shareholder will receive a statement that shows the tax
status of dividends and distributions received the previous year. Distributions
declared in December but paid in January are taxable as if they were paid in
December.

If a taxable shareholder invests in the Portfolio shortly before the record
date of a taxable distribution, the distribution will lower the value of the
Portfolio's shares by the amount of the distribution and, in effect, the
shareholder will receive some of the shareholder's investment back in the form
of a taxable distribution.

Taxes

In general, if a shareholder is a taxable investor, Portfolio distributions
are taxable to the shareholder at either ordinary income or capital gains tax
rates. This is true whether the shareholder reinvests distributions in
additional Portfolio shares or receives them in cash. A distribution of an
amount in excess of the Portfolio's taxable income and capital gains realized
during a taxable year is treated as a non-taxable return of capital that reduces
a shareholder's tax basis in Portfolio shares.

The sale of shares of the Portfolio is a taxable event and may result in a
capital gain or loss to shareholders who are subject to tax. Capital gains or
loss may be realized from an ordinary redemption of shares or an exchange of
shares between two Portfolios. Any loss incurred on 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.

By law, the Portfolio is required to withhold 28% of taxable dividends,
capital gains distributions, and redemption proceeds paid to shareholders who do
not provide their proper taxpayer identification number and certain required
certifications. Shareholders may avoid this withholding requirement by providing
and certifying on the account registration form their correct Taxpayer
Identification Number and by certifying that they are not subject to backup
withholding and are U.S. persons (including U.S. resident aliens). The Portfolio
must also withhold if the IRS instructs it to do so.

Non-U.S. investors are subject to U.S. withholding tax at a 30% or lower
treaty rate on dividends paid by the Portfolio, subject to limited exemptions
for dividends designated as capital gain dividends, short-term capital gain
dividends, interest-related dividends, and exempt-interest dividends. The
exemptions from withholding for short-term capital gain dividends and
interest-related dividends sunset and will no longer apply to dividends paid
with respect to taxable years of the Portfolio beginning after December 31, 2007
unless such exemptions are extended or made permanent. Notwithstanding such
exemptions, non-U.S. investors are subject to backup withholding at a rate of
28% on dividends, capital gains distributions, and redemption proceeds paid to
shareholders who fails to properly certify they are not U.S. persons. Non-U.S.
investors also may be subject to U.S. estate tax.

In addition to federal taxes, shareholders may be subject to state and
local taxes on distributions from a 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.

PURCHASE OF SHARES

Investors may purchase shares of the Portfolio by first contacting the
Advisor at (310) 395-8005 to notify the Advisor of the proposed investment. 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, as approved from time to time
by the Advisor (together, "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.

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 (310) 395-8005 to notify the Advisor of the proposed investment,
then requesting the bank to transmit immediately available funds (federal funds)
by wire to PNC Bank, N.A. for the account of DFA Investment Dimensions Group
Inc. (DFA Selectively Hedged Global Fixed Income 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
send their check to DFA Investment Dimensions Group Inc., c/o PFPC Inc., P.O.
Box 8916, Wilmington, Delaware 19899-8916.

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
also may 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
otherwise represented in its portfolio as described in this Prospectus or in
exchange for local currencies in which such securities of the Portfolio are
denominated. Securities and local currencies accepted by the Fund for exchange
and Portfolio shares to be issued in 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, interests, subscription, or other rights
pertaining to such securities shall become the property of the Portfolio 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 for wire instructions.

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. The Fund will accept such securities for investment and
not for resale.

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.

In addition, the Portfolio may be more susceptible to the risks of
short-term trading than other funds. The nature of the holdings of the Portfolio
may present opportunities for a shareholder to engage in a short-term trading
strategy that exploits possible delays between changes in the prices of the
Portfolio's holdings and the reflection of those price changes in the
Portfolio's net asset value (called "arbitrage market timing"). Such delays may
occur because the Portfolio has significant investments in foreign securities
where, due to time zone differences, the values of those securities are
established some time before the Portfolio calculates its net asset value. In
such circumstances, the available market prices for such foreign securities may
not accurately reflect the latest indications of value at the time the Portfolio
calculates its net asset value. There is a possibility that arbitrage market
timing may dilute the value of the Portfolio's shares if redeeming shareholders
receive proceeds (and purchasing shareholders receive shares) based upon a net
asset value that does not reflect appropriate fair value prices.

The Board has adopted a policy (the "Trading Policy") and the Advisor and
DFA Securities Inc. (collectively, "Dimensional") and their agents have
implemented the following procedures, which are designed to discourage and
prevent market timing or excessive short-term trading in the Portfolio: (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 the 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 the
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 the 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 $5,000; (ii) purchases
and redemptions by U.S. registered investment companies that operate as funds of
funds pursuant to Section 12(d)(1)(G) of the 1940 Act or an SEC exemptive order,
and non-U.S. investment companies that operate as funds of funds (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 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 Portfolio (or other portfolios 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 (and other portfolios of the Fund) 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 purchase blocking procedures of the Trading Policy may not apply to
redemptions by shareholders whose shares are held on the books of Intermediaries
if the Intermediaries have not adopted procedures to implement this Policy. The
Fund and Dimensional will work with Intermediaries to develop such policies to
institute the 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.
An investor that invests in the Portfolio through an Intermediary should contact
the Intermediary for information concerning the policies and procedures that
apply to the investor.

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 and the redemption is consistent with the
interests of the remaining shareholders of the Portfolio.

In addition to monitoring trade activity, the Board has adopted fair value
pricing procedures that govern the pricing of the securities of the Portfolio.
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.

VALUATION OF SHARES

Net Asset Value

The net asset value per share of the Portfolio is calculated after the
close of the NYSE (normally, 1:00 p.m. PT) by dividing the total value of the
Portfolio's investments and other assets, less any liabilities, by the total
outstanding shares of the stock of the Portfolio. The Portfolio generally
calculates its net asset value per share and accepts 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 1:00 p.m. PT.

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

Securities held by the Portfolio (including over-the-counter securities)
are valued at the last quoted sales price of the day. Securities held by the
Portfolio that are listed on Nasdaq are valued at the Nasdaq Official Closing
Price ("NOCP"). If there is no last reported sales price or NOCP of the day, the
Portfolio values the securities at the mean between the most recent quoted bid
and asked prices. Price information on listed securities is taken from the
exchange where the security is primarily traded. Generally, securities issued by
open-end investment companies 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 shares of the Portfolio will tend to fluctuate with interest
rates because, unlike money market funds, the Portfolio does not seek to
stabilize the value of its shares by use of the "amortized cost" method of asset
valuation. Net asset value includes interest on fixed income securities, which
is accrued daily. 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.
Securities that 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.

The value of the securities and other assets of the Portfolio 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. Fair value
pricing also may 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 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 could obtain the fair value assigned to a
security if the Portfolio were to sell the security at approximately the time at
which the Portfolio determines its net asset value per share. As a result, the
sale or redemption by the Portfolio 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 value per share of the Portfolio is expressed in U.S. dollars
by translating the net assets of the Portfolio using the mean of the most recent
bid and asked prices for the dollar as quoted by generally recognized reliable
sources.

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 a Portfolio or Master 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 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 appoint,
from time to time, 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 ("Sub-designees") 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 Sub-designee, as applicable, that is authorized to receive
purchase orders. If the investor buys shares through an Intermediary or
Sub-designee, the purchase price will be the public offering price next
calculated after the Intermediary or Sub-designee, as applicable, receives the
order, rather than on the day the custodian receives the investor's payment
(provided that the Intermediary or Sub-designee, as applicable, has received the
investor's purchase order in good order, and the investor has complied with the
Intermediary's or Sub-designee's payment procedures). No reimbursement fee or
sales charge is imposed on purchases.

EXCHANGE OF SHARES

Investors may exchange shares of the Portfolio for shares of another
portfolio by first contacting the Advisor at (310) 395-8005 to notify the
Advisor of the proposed exchange and then completing a letter of instruction and
mailing it to DFA Investment Dimensions Group Inc., as follows:

Attn: Client Operations
1299 Ocean Avenue
Santa Monica, CA 90401

Investors in the Portfolio also may exchange all or part of their Portfolio
shares into certain portfolios of Dimensional Investment Group Inc., subject to
the minimum purchase requirement set forth in the applicable portfolio's
prospectus. Investors may contact the Advisor at the above-listed phone number
for more information on such exchanges and to request a copy of the prospectuses
of the portfolios of Dimensional Investment Group Inc.

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, the exchange
privilege may be terminated, and any proposed exchange is 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 of the shares; and if the Fund does not have on
file the authorized signatures for the account, proof of authority and a
guarantee of the signature of each registered owner by an "eligible guarantor
institution." Such institutions generally include national or state banks,
savings associations, savings and loan associations, trust companies, savings
banks, credit unions, and members of a recognized stock exchange. 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 (310) 395-8005. The Portfolio will redeem shares at the net asset
value of such shares next determined after receipt of a request for redemption
in good order, by the transfer agent (or by an Intermediary or a Sub-designee,
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 authorized representatives thereof) of the shares; and if
the Fund does not have on file the authorized signatures for the account, proof
of authority and a guarantee of the signature of each registered owner by an
eligible guarantor institution; and any other required supporting legal
documents. A signature guarantee may be obtained from a domestic bank or trust
company, broker, dealer, clearing agency or savings association who are
participants in a medallion program recognized by the Securities Transfer
Association. The three recognized medallion programs are Securities Transfer
Agents Medallion Program (STAMP), Stock Exchanges Medallion Program (SEMP), and
New York Stock Exchange, Inc. Medallion Signature Program (MSP). Signature
guarantees that are not a part of these programs will not be accepted.

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 the shareholders 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.
Investors may avoid this delay by submitting a certified check along with the
purchase order.

Redemption of Small Accounts

With respect to the Portfolio, the Fund reserves the right to redeem a
shareholder's account if the value of the shares in the Portfolio is $500 or
less because of redemptions by the shareholder. Before the Fund involuntarily
redeems shares from such an account and sends the proceeds to the shareholder,
the Fund will give written notice of the redemption to the shareholder at least
sixty days before the redemption date. The shareholder will then have sixty days
from the date of the notice to make an additional investment in the Fund 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 shareholder 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.

In-Kind Redemptions

When in the best interests of the Portfolio, it may make a redemption
payment, in whole or in part, by a distribution of portfolio securities in lieu
of cash. Such distributions will be made in accordance with the federal
securities laws and regulations governing mutual funds in accordance with Rule
18f-1 under the Investment Company Act of 1940. The Portfolio also reserves the
right to redeem its shares in the currencies in which its investments are
denominated. Investors may incur brokerage charges and other transaction costs
in selling such securities and converting such currencies to dollars. Also, the
value of foreign securities or currencies may be affected by currency exchange
fluctuations.

DISCLOSURE OF PORTFOLIO HOLDINGS

The Portfolio 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,
as of the most recent month-end, online at the Advisor's public website,
http://www.dfaus.com, within 20 days after the end of each month. The Portfolio
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,
three months following the month-end. Please consult the SAI for a description
of the other policies and procedures that govern disclosure of the portfolio
holdings by the Portfolio.

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 those of other members of your household, please call us
collect at (310) 395-8005. We will begin sending individual copies of the
shareholder documents to you within 30 days of receiving your request.

PORTFOLIO CHARACTERISTICS AND POLICIES

The following information supplements the information set forth in the
Prospectus of the Portfolios. Capitalized terms not otherwise defined in this
SAI have the meaning assigned to them in the Prospectus.

Dimensional Fund Advisors LP (the "Advisor") serves as investment advisor
to each Portfolio. The Advisor is organized as a Delaware limited partnership
and is controlled and operated by its general partner, Delaware Holdings Inc., a
Delaware corporation. Prior to November 3, 2006, the Advisor was named
Dimensional Fund Advisors Inc. and was organized as a Delaware corporation.

Each Portfolio is diversified under the federal securities laws and
regulations.

Because the structure of the Portfolios is based on the relative market
capitalizations of eligible holdings, it is possible that the Portfolios might
include at least 5% of the outstanding voting securities of one or more issuers.
In such circumstances, a Portfolio and the issuer would be deemed affiliated
persons and certain requirements under the federal securities laws and
regulations regulating dealings between mutual funds and their affiliates might
become applicable. However, based on the present capitalizations of the groups
of companies eligible for inclusion in a Portfolio and the anticipated amount of
a Portfolio's assets intended to be invested in such securities, management does
not anticipate that a Portfolio will include as much as 5% of the voting
securities of any issuer.

BROKERAGE TRANSACTIONS

Portfolio transactions of each Portfolio will be placed with a view to
receiving the best price and execution. In addition, the Advisor will seek to
acquire and dispose of securities in a manner that would cause as little
fluctuation in the market prices of stocks being purchased or sold as possible
in light of the size of the transactions being effected, and brokers will be
selected with this goal in view. The Advisor monitors the performance of brokers
that effect transactions for the Portfolios to determine the effect that the
brokers' trading has on the market prices of the securities in which the
Portfolios invest. The Advisor also checks the rate of commission being paid by
the Portfolios to their brokers to ascertain that the rates are competitive with
those charged by other brokers for similar services.

Transactions also may be placed with brokers who provide the Advisor with
investment research, such as reports concerning individual issuers, industries,
and general economic and financial trends, and other research services. The
Investment Advisory Agreement for each Portfolio permits the Advisor knowingly
to pay commissions on these transactions that are greater than another broker,
dealer, or exchange member might charge if the Advisor, in good faith,
determines that the commissions paid are reasonable in relation to the research
or brokerage services provided by the broker or dealer when viewed in terms of
either a particular transaction or the Advisor's overall responsibilities to the
accounts under the Advisor's management. Research services furnished by brokers
through whom securities transactions are effected may be used by the Advisor in
servicing all of its accounts and not all such services may be used by the
Advisor with respect to the Portfolios.

Subject to obtaining best price and execution, transactions may be placed
with brokers that have assisted in the sale of Fund shares. The Advisor,
however, pursuant to policies and procedures approved by the Board of Directors
of the Fund, is prohibited from selecting brokers and dealers to effect a
Portfolio's securities transactions based (in whole or in part) on a broker's or
dealer's promotion or sale of shares issued by a Portfolio or any other
registered investment companies.

Some companies eligible for purchase by a Portfolio may be thinly traded
securities. Therefore, the Advisor believes it needs maximum flexibility to
effect trades on a best execution basis. To that end, the Advisor places buy and
sell orders for a Portfolio with market makers, third-party brokers, electronic
communications networks ("ECNs"), and with dealers on an agency basis.
Third-party brokers enable the Advisor to trade with other institutional holders
directly on a net basis. This allows the Advisor sometimes to trade larger
blocks than would be possible by going through a single market maker.

ECNs, such as Instinet, are electronic information and communication
networks whose subscribers include most market makers as well as many
institutions. Such ECNs charge a commission for each trade executed on their
systems. For example, on any given trade, a Portfolio, by trading through an
ECN, could pay a spread to a dealer on the other side of the trade plus a
commission to the ECN. However, placing a buy (or sell) order on an ECN
communicates to many (potentially all) market makers and institutions at once.
This can create a more complete picture of the market and thus increase the
likelihood that a Portfolio can effect transactions at the best available
prices.

Because the Portfolios had not commenced investment operations prior to the
date of this SAI, the Portfolios have not incurred any brokerage commissions
that are required to be reported.

INVESTMENT LIMITATIONS

Each Portfolio has adopted certain limitations that may not be changed with
respect to the Portfolio without the approval of a majority of the outstanding
voting securities of the Portfolio. A "majority" is defined as the lesser of:
(1) at least 67% of the voting securities of the Portfolio (to be affected by
the proposed change) present at a meeting, if the holders of more than 50% of
the outstanding voting securities of the Portfolio are present or represented by
proxy, or (2) more than 50% of the outstanding voting securities of such
Portfolio.

Each Portfolio will not:

(1) purchase or sell real estate, unless acquired as a result of ownership
of securities or other instruments and provided that this restriction
does not prevent the Portfolio from investing in issuers that invest,
deal, or otherwise engage in transactions in real estate or interests
therein, or investing in securities that are secured by real estate or
interests therein;

(2) purchase or sell physical commodities, unless acquired as a result of
ownership of securities or other instruments and provided that this
restriction does not prevent the Portfolio from engaging in
transactions involving futures contracts and options thereon or
investing in securities that are secured by physical commodities;

(3) make loans to other persons, except: (a) through the lending of its
portfolio securities; (b) through the purchase of debt securities,
loan participations and/or engaging in direct corporate loans for
investment purposes in accordance with its investment objective and
policies; and (c) to the extent the entry into a repurchase agreement
is deemed to be a loan;

(4) purchase the securities of any one issuer (other than the U.S.
government or any of its agencies or instrumentalities or securities
of other investment companies) if immediately after such investment:
(a) more than 5% of the value of the Portfolio's total assets would be
invested in such issuer, or (b) more than 10% of the outstanding
voting securities of such issuer would be owned by the Portfolio,
except that up to 25% of the value of the Portfolio's total assets may
be invested without regard to such 5% and 10% limitations;

(5) borrow money, except that it may: (a) borrow from banks (as defined in
the 1940 Act) or other financial institutions in amounts up to 33 1/3%
of its total assets (including the amount borrowed), and (b) to the
extent permitted by applicable law, borrow up to an additional 5% of
its total assets for temporary purposes;

(6) issue senior securities (as such term is defined in Section 18(f) of
the 1940 Act), except to the extent permitted under the 1940 Act;

(7) engage in the business of underwriting securities issued by others;
and

(8) concentrate (invest more than 25% of its net assets) in securities of
issuers in a particular industry (other than securities issued or
guaranteed by the U.S. government or any of its agencies or securities
of other investment companies).

Although not a fundamental policy subject to shareholder approval, each
Portfolio does not intend to invest more than 15% of its net assets in illiquid
securities.

With respect to the investment limitation described in 5(a) above, a
Portfolio will maintain asset coverage of at least 300% (as described in the
1940 Act), inclusive of any amounts borrowed. With respect to any borrowings by
a Portfolio and with respect to the investment limitation described in 5(b)
above, a Portfolio will segregate assets to cover the amount borrowed by the
Portfolio. The Portfolios currently do not intend to borrow money for investment
purposes.

Subject to future regulatory guidance, for purposes of those investment
limitations identified above that are based on total assets, "total assets"
refers to the assets that a Portfolio owns, and does not include assets that the
Portfolio does not own but over which it has effective control. For example,
when applying a percentage investment limitation that is based on total assets,
a Portfolio will exclude from its total assets those assets that represent
collateral received by the Portfolio for its securities lending transactions.

Unless otherwise indicated, all limitations applicable to a Portfolio's
investments apply only at the time that a transaction is undertaken. Any
subsequent change in a rating assigned by any rating service to a security or
change in the percentage of a Portfolio's assets invested in certain securities
or other instruments resulting from market fluctuations or other changes in the
Portfolio's total assets will not require the Portfolio to dispose of an
investment until the Advisor determines that it is practicable to sell or
closeout the investment without undue market or tax consequences. In the event
that ratings services assign different ratings to the same security, the Advisor
will determine which rating the Advisor believes best reflects the security's
quality and risk at that time, which may be the higher of the several assigned
ratings.

FUTURES CONTRACTS

Each Portfolio may use 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.

Futures contracts provide for the future sale by one party and purchase by
another party of a specified amount of defined securities at a specified future
time and at a specified price. Futures contracts that are standardized as to
maturity date and underlying financial instrument are traded on national futures
exchanges. Each Portfolio will be required to make a margin deposit in cash or
government securities with a futures commission merchant (an "FCM") to initiate
and maintain positions in futures contracts. Minimal initial margin requirements
are established by the futures exchanges and FCMs may establish margin
requirements that are higher than the exchange requirements. After a futures
contract position is opened, the value of the contract is marked to market
daily. If the futures contract price changes, to the extent that the margin on
deposit does not satisfy margin requirements, payment of additional "variation"
margin to be held by the FCM will be required. Conversely, reduction in the
contract value may reduce the required margin resulting in a repayment of excess
margin to the custodial account of the Portfolio. Variation margin payments may
be made to and from the futures broker for as long as the contract remains open.
Each Portfolio expects to earn income on its margin deposits. Each Portfolio
intends to limit its futures-related investment activity so that other than with
respect to bona fide hedging activity (as defined in Commodity Futures Trading
Commission ("CFTC") General Regulations Section 1.3(z)): (i) the aggregate
initial margin and premiums paid to establish commodity futures and commodity
option contract positions (determined at the time the most recent position was
established) do not exceed 5% of the liquidation value of the Portfolio, after
taking into account unrealized profits and unrealized losses on any such
contracts the Portfolio has entered into (provided that, in the case of an
option that is in-the-money at the time of purchase, the in-the-money amount may
be excluded in calculating such 5% limitation), or (ii) the aggregate net
"notional value" (i.e., the size of a commodity futures or commodity option
contract in contract units (taking into account any multiplier specified in the
contract), multiplied by the current market price (for a futures contract) or
strike price (for an option contract) of each such unit) of all non-hedge
commodity futures and commodity option contracts that the Portfolio has entered
into (determined at the time the most recent position was established) does not
exceed the liquidation value of the Portfolio, after taking into account
unrealized profits and unrealized losses on any such contracts that the
Portfolio has entered into.

Positions in futures contracts may be closed out only on an exchange that
provides a secondary market. However, there can be no assurance that a liquid
secondary market will exist for any particular futures contract at any specific
time. Therefore, it might not be possible to close a futures position and, in
the event of adverse price movements, a Portfolio would continue to be required
to make variation margin deposits. In such circumstances, if a Portfolio has
insufficient cash, it might have to sell portfolio securities to meet daily
margin requirements at a time when it might be disadvantageous to do so.
Management intends to minimize the possibility that it will be unable to close
out a futures contract by only entering into futures that are traded on national
futures exchanges and for which there appears to be a liquid secondary market.
Pursuant to published positions of the Securities and Exchange Commission (the
"SEC") and interpretations of the staff of the SEC, a Portfolio (or its
custodian) is required to maintain segregated accounts or to segregate assets
through notations on the books of the custodian, consisting of liquid assets
(or, as permitted under applicable interpretations, enter into offsetting
positions) in connection with its futures contract transactions in order to
cover its obligations with respect to such contracts. These requirements are
designed to limit the amount of leverage that a Portfolio may use by entering
into future transactions.

CASH MANAGEMENT PRACTICES

Each Portfolio engages in cash management practices in order to earn income
on uncommitted cash balances. Generally, cash is uncommitted pending investment
in other securities, payment of redemptions, or in other circumstances where the
Advisor believes liquidity is necessary or desirable. For example, a Portfolio
may make cash investments for temporary defensive purposes during periods in
which market, economic, or political conditions warrant.

Each Portfolio may invest cash in short-term repurchase agreements. In
addition, each Portfolio may invest a portion of its assets, ordinarily not more
than 20%, in money market instruments, debt securities that at the time of
purchase have an investment grade rating by a rating agency or are deemed to be
investment grade by the Advisor, freely convertible currencies, shares of
affiliated and unaffiliated registered and unregistered money market mutual
funds, index futures contracts, and options thereon. Investments in money market
mutual funds may involve a duplication of certain fees and expenses. The 20%
guideline is not an absolute limitation but each Portfolio does not expect to
exceed this guideline under normal circumstances.

EXCHANGE-TRADED FUNDS

Each Portfolio may also invest in exchange-traded funds ("ETFs") and
similarly structured pooled investments for the purpose of gaining exposure to
the equity markets, including the United States equity market, while maintaining
liquidity. An ETF is an investment company whose goal is to track or replicate a
desired index, such as a sector, market, or global segment. ETFs are passively
managed, and traded similarly to a publicly traded company. The risks and costs
of investing in ETFs are similar to those of investing in a publicly traded
company. The goal of an ETF is to correspond generally to the price and yield
performance, before fees and expenses, of its underlying index. The risk of not
correlating to the index is an additional risk to the investors of ETFs. When a
Portfolio invests in an ETF, shareholders of the Portfolio bear their
proportionate share of the underlying ETF's fees and expenses. ETFs in which the
Portfolios invest are not subject to, although they may incorporate, the
Portfolios' environmental impact considerations. (See the Portfolios' prospectus
for information regarding the Portfolios' environmental impact considerations.)

CONVERTIBLE DEBENTURES

The International Sustainability Core 1 Portfolio (the "International
Portfolio") may invest up to 5% of its assets in convertible debentures issued
by non-U.S. companies located in the countries in which it is permitted to
invest. Convertible debentures include corporate bonds and notes that may be
converted into or exchanged for common stock. These securities are generally
convertible either at a stated price or a stated rate (that is, for a specific
number of shares of common stock or other security). As with other fixed income
securities, the price of a convertible debenture, to some extent, varies
inversely with interest rates. While providing a fixed income stream (generally
higher in yield than the income derived from a common stock, but lower than that
afforded by a nonconvertible debenture), a convertible debenture also affords
the investor an opportunity, through its conversion feature, to participate in
the capital appreciation of the common stock into which the debenture is
convertible. As the market price of the underlying common stock declines,
convertible debentures tend to trade increasingly on a yield basis and so may
not experience market value declines to the same extent as the underlying common
stock. When the market price of the underlying common stock increases, the price
of a convertible debenture tends to rise as a reflection of the value of the
underlying common stock. To obtain such a higher yield, the International
Portfolio may be required to pay for a convertible debenture an amount in excess
of the value of the underlying common stock. Common stock acquired by the
International Portfolio upon conversion of a convertible debenture will
generally be held for as long as the Advisor anticipates such stock will provide
the Portfolio with opportunities that are consistent with the Portfolio's
investment objective and policies.

DIRECTORS AND OFFICERS

Directors

The Board of Directors of the Fund is responsible for establishing the
Fund's policies and for overseeing the management of the Fund.

The Board of Directors has two standing committees, the Audit Committee and
the Portfolio Performance and Service Review Committee (the "Performance
Committee"). The Audit Committee is comprised of George M. Constantinides, Roger
G. Ibbotson, and Abbie J. Smith. Each member of the Audit Committee is a
disinterested Director. The Audit Committee for the Board oversees the Fund's
accounting and financial reporting policies and practices, the Fund's internal
controls, the Fund's financial statements and the independent audits thereof,
and performs other oversight functions as requested by the Board. The Audit
Committee for the Board recommends the appointment of the Fund's independent
registered public accounting firm and also acts as a liaison between the Fund's
independent registered public accounting firm and the full Board. There were
four Audit Committee meetings for the Fund held during the fiscal year ended
November 30, 2007.

The Performance Committee is comprised of Messrs. Constantinides and
Ibbotson, Ms. Smith, John P. Gould, Myron S. Scholes, and Robert C. Merton. Each
member of the Fund's Performance Committee is a disinterested Director. The
Performance Committee regularly reviews and monitors the investment performance
of the Fund's series, including the Portfolios, and reviews the performance of
the Fund's service providers. There were six Performance Committee meetings held
during the fiscal year ended November 30, 2007.

Certain biographical information for each disinterested Director and each
interested Director of the Fund is set forth in the tables below, including a
description of each Director's experience as a Director of the Fund and as a
director or trustee of other funds, as well as other recent professional
experience.

+ The term DFA Fund Complex refers to the four registered investment
companies for which the Advisor performs advisory or administrative
services and for which the individuals listed above serve as
directors/trustees on the Boards of Directors/Trustees of such companies.

* Under a deferred compensation plan (the "Plan") adopted effective January
1, 2002, the disinterested Directors of the Fund may defer receipt of all
or a portion of the compensation for serving as members of the four Boards
of Directors/Trustees of the investment companies in the DFA Fund Complex
(the "DFA Funds"). Amounts deferred under the Plan are treated as though
equivalent dollar amounts had been invested in shares of a cross-section of
the DFA Funds (the "Reference Funds"). The amounts ultimately received by
the disinterested Directors under the Plan will be directly linked to the
investment performance of the Reference Funds. Deferral of fees in
accordance with the Plan will have a negligible effect on a fund's assets,
liabilities, and net income per share, and will not obligate a fund to
retain the services of any disinterested Director or to pay any particular
level of compensation to the disinterested Director. The total amount of
deferred compensation accrued by the disinterested Directors from the DFA
Fund Complex who participated in the Plan during the fiscal year ended
November 30, 2006 is as follows: $130,000 (Mr. Gould), $137,500 (Mr.
Ibbotson); $130,000 (Mr. Scholes); and $130,000 (Ms. Smith). A
disinterested Director's deferred compensation will be distributed at the
earlier of: (a) January in the year after the disinterested Director's
resignation from the Boards of Directors/Trustees of the DFA Funds, or
death or disability, or (b) five years following the first deferral, in
such amounts as the disinterested Director has specified. The obligations
of the DFA Funds to make payments under the Plan will be unsecured general
obligations of the DFA Funds, payable out of the general assets and
property of the DFA Funds.

(1) Each officer holds office for an indefinite term at the pleasure of the
Board of Directors and until his or her successor is elected and qualified.

Because each Portfolio had not been offered prior to the date of this SAI,
Directors and officers as a group own less than 1% of the outstanding shares of
each Portfolio.

SERVICES TO THE PORTFOLIOS

Administrative Services

PFPC Inc. ("PFPC"), 301 Bellevue Parkway, Wilmington, DE 19809, serves as
the accounting services, dividend disbursing, and transfer agent for the
Portfolios. The services provided by PFPC are subject to supervision by the
executive officers and the Board of Directors of the Fund and include day-to-day
keeping and maintenance of certain records, calculation of the offering price of
the shares, preparation of reports, liaison with its custodian, and transfer and
dividend disbursing agency services. For the administrative and accounting
services provided by PFPC, the Portfolios pay PFPC annual fees that are
calculated daily and paid monthly according to a fee schedule based on the
aggregate average net assets of the Fund Complex, which includes four registered
investment companies and a group trust. The fee schedule is set forth in the
table below:

.0110% of the Fund Complex's first $50 billion of average net assets;
.0085% of the Fund Complex's next $25 billion of average net assets; and
.0075% of the Fund Complex's average net assets in excess of $75 billion.

The fees charged to each Portfolio under the fee schedule are allocated to a
Portfolio based on the Portfolio's pro-rata portion of the aggregate average net
assets of the Fund Complex.

Each Portfolio also is subject to a monthly base fee. The U.S.
Sustainability Core 1 Portfolio (the "U.S. Portfolio") is subject to a monthly
base fee of $1,666. The International Portfolio is subject to a monthly base fee
of $2,083. Each Portfolio also pays separate fees to PFPC with respect to the
services PFPC provides as transfer agent and dividend disbursing agent.

Custodians

Citibank, N.A., 111 Wall Street, New York, New York, 10005, is the global
custodian for the International Portfolio. PFPC Trust Company, 301 Bellevue
Parkway, Wilmington, DE 19809, serves as the custodian for the U.S. Portfolio.

A Portfolio's custodian maintains a separate account or accounts for the
Portfolio; receives, holds, and releases portfolio securities on account of the
Portfolio; makes receipts and disbursements of money on behalf of the Portfolio;
and collects and receives income and other payments and distributions on account
of the Portfolio's portfolio securities.

Distributor

The Fund's shares are distributed by DFA Securities Inc. ("DFAS"), a
wholly-owned subsidiary of the Advisor. DFAS is registered as a limited purpose
broker-dealer under the Securities Exchange Act of 1934 and is a member of the
National Association of Securities Dealers, Inc. The principal business address
of DFAS is 1299 Ocean Avenue, Santa Monica, California 90401.

DFAS acts as an agent of the Fund by serving as the principal underwriter
of the Fund's shares. Pursuant to the Distribution Agreement with the Fund, DFAS
uses its best efforts to seek or arrange for the sale of shares of the Fund,
which are continuously offered. No sales charges are paid by investors or the
Fund. No compensation is paid by the Fund to DFAS under the Distribution
Agreement.

Legal Counsel

Stradley, Ronon, Stevens & Young, LLP serves as legal counsel to the Fund.
Its address is 2600 One Commerce Square, Philadelphia, PA 19103-7098.

Independent Registered Public Accounting Firm

PricewaterhouseCoopers LLP ("PwC") is the independent registered public
accounting firm to the Fund and audits the annual financial statements of the
Fund. PwC's address is Two Commerce Square, Suite 1700, 2001 Market Street,
Philadelphia, PA 19103-7042.

ADVISORY FEES

David G. Booth and Rex A. Sinquefield, as directors and/or officers of the
Advisor and shareholders of the outstanding stock of the Advisor's general
partner, may be deemed controlling persons of the Advisor. For the services it
provides as investment advisor to each Portfolio, the Advisor is paid a monthly
fee calculated as a percentage of average net assets of the Portfolio. As of the
date of this SAI, the Portfolios had not yet commenced operations, so the
Portfolios have not paid any management fees.

Pursuant to a Fee Waiver and Expense Assumption Agreement for each
Portfolio, the Advisor has agreed to waive all or a portion of its management
fee and to assume the ordinary operating expenses of the Portfolio (excluding
the expenses that the Portfolio incurs indirectly through its investment in
other investment companies) ("Portfolio Expenses") to the extent necessary to
limit the Portfolio Expenses of the U.S. Portfolio and International Portfolio
to 0.35% and 0.55%, respectively, of each Portfolio's average net assets on an
annualized basis (the "Expense Limitation Amount"). At any time that the
Portfolio Expenses of a Portfolio are less than the Portfolio's Expense
Limitation Amount, 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 Portfolio's annualized Portfolio Expenses
to exceed the Portfolio's Expense Limitation Amount. A 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. The Fee Waiver and Expense Assumption Agreement will remain
in effect for an initial period until April 1 2009, and then shall continue in
effect from year to year for one-year periods thereafter unless terminated by
the Advisor.

PORTFOLIO MANAGERS

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 including
running buy and sell programs based on the parameters established by the
Investment Committee. The portfolio managers named below coordinate the efforts
of all other portfolio managers with respect to the day-to-day management of the
Portfolios indicated.

U.S. Portfolio Robert T. Deere
International Portfolio Karen E. Umland

Because each Portfolio had not commenced operations prior to the date of
this SAI, the portfolio managers do not own any shares of the Portfolios.

Description of Compensation Structure

Portfolio managers receive a base salary and bonus. Compensation of a
portfolio manager is determined at the discretion of the Advisor and is based on
a portfolio manager's experience, responsibilities, the perception of the
quality of his or her work efforts, and other subjective factors. The
compensation of portfolio managers is not directly based upon the performance of
the Portfolios or other accounts that the portfolio managers manage. The Advisor
reviews the compensation of each portfolio manager annually and may make
modifications in compensation as the Advisor's Compensation Committee deems
necessary to reflect changes in the market. Each portfolio manager's
compensation consists of the following:

o Base salary. Each portfolio manager is paid a base salary. The
Advisor considers the factors described above to determine each portfolio
manager's base salary.

o Semi-Annual Bonus. Each portfolio manager may receive a semi-annual
bonus. The amount of the bonus paid to each portfolio manager is based upon
the factors described above.

Portfolio managers may be awarded the right to purchase restricted shares
of stock of the Advisor's general partner as determined from time to time by the
Board of Directors of the Advisor or its delegees. Portfolio managers also
participate in benefit and retirement plans and other programs available
generally to all employees.

Other Managed Accounts

In addition to the Portfolios, the portfolio managers manage: (i) other
U.S. registered investment companies advised or sub-advised by the Advisor; (ii)
other pooled investment vehicles that are not U.S. registered mutual funds; and
(iii) other accounts managed for organizations and individuals. The following
table sets forth information regarding the total accounts for which each
portfolio manager has the primary responsibility for coordinating the day-to-day
management responsibilities:

Name of Portfolio Manager Number of Accounts Managed and Total
Assets by Category As of November 30, 2006
---------------------------------- -------------------------------------------------------------------------
o 23 U.S. registered mutual funds with $45,702 million in total
Robert T. Deere assets under management.
o 8 unregistered pooled investment vehicles with $10,498 million in
total assets under management. Out of these unregistered pooled
investment vehicles, one client with an investment of $304 million
in an unregistered pooled investment vehicle pays a
performance-based advisory fee.
o 41 other accounts with $3,371 million in total assets under
management.
---------------------------------- -------------------------------------------------------------------------
o 24 U.S. registered mutual funds with $35,356 million in total
Karen E. Umland assets under management.
o 4 unregistered pooled investment vehicles with $557 million in
total assets under management.
o 7 other accounts with $2,896 million in total assets under
management.
---------------------------------- -------------------------------------------------------------------------

Potential Conflicts of Interest

Actual or apparent conflicts of interest may arise when a portfolio manager
has the primary day-to-day responsibilities with respect to more than one
portfolio and other accounts. Other accounts include registered mutual funds
(other than the Portfolios), other unregistered pooled investment vehicles, and
other accounts managed for organizations and individuals ("Accounts"). An
Account may have similar investment objectives to a Portfolio, or may purchase,
sell, or hold securities that are eligible to be purchased, sold, or held by a
Portfolio. Actual or apparent conflicts of interest include:

o Time Management. The management of multiple portfolios and/or Accounts may
result in a portfolio manager devoting unequal time and attention to the
management of each portfolio and/or Account. The Advisor seeks to manage
such competing interests for the time and attention of portfolio managers
by having portfolio managers focus on a particular investment discipline.
Most Accounts managed by a portfolio manager are managed using the same
investment models that are used in connection with the management of the
Portfolios.

o Investment Opportunities. It is possible that at times identical securities
will be held by more than one portfolio and/or Account. However, positions
in the same security may vary and the length of time that any portfolio or
Account may choose to hold its investment in the same security may likewise
vary. If a portfolio manager identifies a limited investment opportunity
that may be suitable for more than one portfolio or Account, a Portfolio
may not be able to take full advantage of that opportunity due to an
allocation of filled purchase or sale orders across all eligible portfolios
and Accounts. To deal with these situations, the Advisor has adopted
procedures for allocating portfolio transactions across multiple portfolios
and Accounts.

o Broker Selection. With respect to securities transactions for the
Portfolios, the Advisor determines which broker to use to execute each
order, consistent with the Advisor's duty to seek best execution of the
transaction. However, with respect to certain Accounts (such as separate
accounts), the Advisor may be limited by the client with respect to the
selection of brokers or may be instructed to direct trades through a
particular broker. In these cases, the Advisor or its affiliates may place
separate, non-simultaneous, transactions for a Portfolio and another
Account that may temporarily affect the market price of the security or the
execution of the transaction, or both, to the detriment of the Portfolio or
the Account.

o Performance-Based Fees. For some Accounts, the Advisor may be compensated
based on the profitability of the Account, such as by a performance-based
management fee. These incentive compensation structures may create a
conflict of interest for the Advisor with regard to Accounts where the
Advisor is paid based on a percentage of assets because the portfolio
manager may have an incentive to allocate securities preferentially to the
Accounts where the Advisor might share in investment gains.

o Investment in an Account. A portfolio manager or his/her relatives may
invest in an Account that he or she manages and a conflict may arise where
he or she may therefore have an incentive to treat the Account in which the
portfolio manager or his/her relatives invest preferentially as compared to
the Portfolio or other Accounts for which he or she has portfolio
management responsibilities.

The Advisor and the Fund have adopted certain compliance procedures that
are reasonably designed to address these types of conflicts. However, there is
no guarantee that such procedures will detect each and every situation in which
a conflict arises.

GENERAL INFORMATION

The Fund was incorporated under Maryland law on June 15, 1981. Until June
1983, the Fund was named DFA Small Company Fund Inc. The Portfolios described in
this SAI had not commenced operations prior to the date of this SAI.

CODE OF ETHICS

The Fund, the Advisor, and DFAS have adopted a Code of Ethics, under Rule
17j-1 of the 1940 Act, for certain access persons of the Portfolios. The Code is
designed to ensure that access persons act in the interest of a Portfolio, and
its shareholders, with respect to any personal trading of securities. Under the
Code, access persons are generally prohibited from knowingly buying or selling
securities (except for mutual funds, U.S. government securities, and money
market instruments) which are being purchased, sold, or considered for purchase
or sale by a Portfolio unless the access persons' proposed purchases are
approved in advance. The Code also contains certain reporting requirements and
personal securities trading clearance procedures.

SHAREHOLDER RIGHTS

The shares of each Portfolio, when issued and paid for in accordance with
the Portfolio's Prospectus, will be fully paid and non-assessable shares. Each
share of common stock of a Portfolio represents an equal proportional interest
in the assets and liabilities of the Portfolio and has identical, non-cumulative
voting, dividend, redemption liquidation, and other rights and preferences.

With respect to matters that require shareholder approval, shareholders are
entitled to vote only with respect to matters that affect the interest of the
portfolio of shares that the shareholders hold, except as otherwise required by
applicable law. If liquidation of the Fund should occur, shareholders would be
entitled to receive, on a per class basis, the assets of the particular
portfolio whose shares they own, as well as a proportionate share of Fund assets
not attributable to any particular portfolio. Ordinarily, the Fund does not
intend to hold annual meetings of shareholders, except as required by the 1940
Act or other applicable law. The Fund's bylaws provide that special meetings of
shareholders shall be called at the written request of shareholders entitled to
be cast not less than a majority of the votes entitled to be cast at such
meeting. Such meeting may be called to consider any matter, including the
removal of one or more directors. Shareholders will receive shareholder
communications with respect to such matters as required by the 1940 Act,
including semi-annual and annual financial statements of the Fund.

Shareholder inquiries may be made by writing or calling the Fund at the
address or telephone number appearing on the cover of this SAI. Only those
individuals whose signatures are on file for the account in question may receive
specific account information or make changes in the account registration.

PRINCIPAL HOLDERS OF SECURITIES

Because the Portfolios had not been offered prior to the date of this SAI,
no person beneficially owned 5% or more of the outstanding shares of a Portfolio
as of the date of this SAI.

PURCHASE OF SHARES

The following information supplements the information set forth in the
Prospectus under the caption "PURCHASE OF SHARES."

The Fund will accept purchase and redemption orders on each day that the
New York Stock Exchange ("NYSE") is open for business, regardless of whether the
Federal Reserve System is closed. However, no purchases by wire may be made on
any day that the Federal Reserve System is closed. The Fund generally will be
closed on days that the NYSE is closed. The NYSE is scheduled to be open Monday
through Friday throughout the year except for days closed to recognize New
Year's Day, Martin Luther King, Jr. Day, Presidents' Day, Good Friday, Memorial
Day, Independence Day, Labor Day, Thanksgiving, and Christmas Day. The Federal
Reserve System is closed on the same days as the NYSE, except that it is open on
Good Friday and closed on Columbus Day and Veterans' Day. Orders for redemptions
and purchases will not be processed if the Fund is closed.

The Fund reserves the right, in its sole discretion, to suspend the
offering of shares of a Portfolio or reject purchase orders when, in the
judgment of management, such suspension or rejection is in the best interest of
the Fund or the Portfolio. Securities accepted in exchange for shares of a
Portfolio will be acquired for investment purposes and will be considered for
sale under the same circumstances as other securities in the Portfolio.

The Fund or its transfer agent may, from time to time, appoint a
sub-transfer agent, such as a broker, for the receipt of purchase and redemption
orders and funds from certain investors. With respect to purchases and
redemptions through a sub-transfer agent, the Fund will be deemed to have
received a purchase or redemption order when the sub-transfer agent receives the
order. Shares of a Portfolio will be priced at the public offering price next
calculated after receipt of the purchase or redemption order by the sub-transfer
agent.

Reimbursement fees may be charged prospectively from time to time based
upon the future experience of a Portfolio, which is currently sold at net asset
value. Any such charges will be described in the Prospectus.

REDEMPTION AND TRANSFER OF SHARES

The following information supplements the information set forth in the
Prospectus under the caption "REDEMPTION OF SHARES."

The Fund may suspend redemption privileges or postpone the date of payment:
(1) during any period when the NYSE is closed, or trading on the NYSE is
restricted as determined by the SEC; (2) during any period when an emergency
exists as defined by the rules of the SEC as a result of which it is not
reasonably practicable for the Fund to dispose of securities owned by it, or
fairly to determine the value of its assets; and (3) for such other periods as
the SEC may permit.

Shareholders may transfer shares of a Portfolio to another person by making
a written request to the Advisor, who will transmit the request to the transfer
agent. The request should clearly identify the account and number of shares to
be transferred, and include the signature of all registered owners and all stock
certificates, if any, which are subject to the transfer. The signature on the
letter of request, the stock certificate, or any stock power must be guaranteed
in the same manner as described in the Prospectus under "REDEMPTION OF SHARES."
As with redemptions, the written request must be received in good order before
any transfer can be made.

TAXATION OF THE PORTFOLIOS

The following is a summary of some of the federal income tax consequences
that may affect the Portfolios. Unless your investment in the Portfolios is
through a retirement plan, you should consider the tax implications of investing
and consult your own tax adviser.

Distributions of Net Investment Income

A Portfolio derives income generally in the form of dividends and interest
on its investments. This income, less expenses incurred in the operation of a
Portfolio, constitutes its net investment income from which dividends may be
paid to you. If you are a taxable investor, any distributions by a Portfolio
from such income (other than qualified dividends) will be taxable to you at
ordinary income tax rates, whether you take them in cash or in additional
shares. A portion of the income dividends paid to shareholders may be qualified
dividends eligible to be taxed at reduced rates.

Distributions of Capital Gain

A Portfolio may realize a capital gain or loss in connection with sales or
other dispositions of its portfolio securities. Distributions derived from the
excess of net short-term capital gain over net long-term capital loss will be
taxable to you as ordinary income. Distributions paid from the excess of net
long-term capital gain over net short-term capital loss will be taxable to you
as long-term capital gain, regardless of how long you have held your shares in a
Portfolio. Any net capital gain of a Portfolio generally will be distributed
once each year, and may be distributed more frequently, if necessary, to reduce
or eliminate excise or income taxes on the Portfolio.

Returns of Capital

If a Portfolio's distributions exceed its taxable income and capital gains
realized during a taxable year, all or a portion of the distributions made in
the same taxable year may be recharacterized as a return of capital to
shareholders. A return of capital distribution generally will not be taxable,
but will reduce each shareholder's cost basis in a Portfolio and result in a
higher reported capital gain or lower reported capital loss when those shares on
which the distribution was received are sold. Any return of capital in excess of
a shareholder's basis, however, is taxable as a capital gain.

Effect of Foreign Withholding Taxes

In general. The International Portfolio may be subject to foreign
withholding taxes on income from certain foreign securities. This, in turn,
could reduce the Portfolio's income dividends paid to shareholders.

Pass-through of foreign tax credits. If more than 50% in value of the total
assets of the International Portfolio is invested in securities of foreign
corporations, the Portfolio may elect to pass through to its shareholders their
pro rata share of foreign income taxes paid by the Portfolio. If this election
is made, the International Portfolio may report more taxable income to you than
it actually distributes. You will then be entitled either to deduct your share
of these taxes in computing your taxable income, or to claim a foreign tax
credit for these taxes against your U.S. federal income tax (subject to
limitations for certain shareholders). The International Portfolio will provide
you with the information necessary to complete your personal income tax return
if it makes this election.

The amount of any foreign tax credits available to you (as a result of the
pass-through to you of your pro rata share of foreign taxes by paid by the
Portfolio) will be reduced if you receive from the International Portfolio
qualifying dividends from qualifying foreign corporations that are subject to
tax at reduced rates. Shareholders in these circumstances should talk with their
personal tax advisors about their foreign tax credits and the procedures that
they should follow to claim these credits on their personal income tax returns.

Effect of foreign debt investments on distributions. Most foreign exchange
gains realized on the sale of debt securities are treated as ordinary income by
a Portfolio. Similarly, foreign exchange losses realized on the sale of debt
securities generally are treated as ordinary losses. These gains when
distributed are taxable to you as ordinary income, and any losses reduce the
Portfolio's ordinary income otherwise available for distribution to you. This
treatment could increase or decrease the Portfolio's ordinary income
distributions to you, and may cause some or all of the Portfolio's previously
distributed income to be classified as a return of capital.

PFIC securities. The International Portfolio may invest in securities of
foreign entities that could be deemed for tax purposes to be passive foreign
investment companies ("PFICs"). When investing in PFIC securities, the Portfolio
intends to mark-to-market these securities and will recognize any gains at the
end of its fiscal year. Deductions for losses are allowable only to the extent
of any current or previously recognized gains. These gains (reduced by allowable
losses) are treated as ordinary income that the Portfolio is required to
distribute, even though it has not sold the securities. You should also be aware
that the designation of a foreign security as a PFIC security will cause its
income dividends to fall outside of the definition of qualified foreign
corporation dividends. These dividends generally will not qualify for the
reduced rate of taxation on qualified dividends when distributed to you by the
Portfolio. In addition, if the Portfolio is unable to identify an investment as
a PFIC and thus does not make a mark-to-market election, the Portfolio may be
subject to U.S. federal income tax on a portion of any "excess distribution" or
gain from the disposition of such shares even if such income is distributed as a
taxable dividend by the Portfolio to its shareholders. Additional charges in the
nature of interest may be imposed on the Portfolio in respect of deferred taxes
arising from such distributions or gains.

Information on the Amount and Tax Character of Distributions.

A Portfolio will inform you of the amount and character of your
distributions at the time they are paid, and will advise you of the tax status
of such distributions for federal income tax purposes shortly after the close of
each calendar year. If you have not held Portfolio shares for a full year, a
Portfolio may designate and distribute to you, as ordinary income, qualified
dividends, or capital gains, and in the case of non-U.S. shareholders the
Portfolio may further designate and distribute as interest-related dividends and
short-term capital gain dividends, a percentage of income that is not equal to
the actual amount of such income earned during the period of your investment in
the Portfolio. Taxable Distributions declared by a Portfolio in December to
shareholders of record in such month, but paid in January, are taxable to you as
if they were paid in December.

Election to be Taxed as a Regulated Investment Company

Each Portfolio intends to qualify each year as a regulated investment
company by satisfying certain distribution and asset diversification
requirements under the Internal Revenue Code (the "Code"). As a regulated
investment company, a Portfolio generally pays no federal income tax on the
income and gains it distributes to its shareholders. The Board of Directors
reserves the right not to distribute a Portfolio's net long-term capital gain or
not to maintain the qualification of a Portfolio as a regulated investment
company if it determines such a course of action to be beneficial to
shareholders. If net long-term capital gain is retained, a Portfolio would be
taxed on the gain, and shareholders would be notified that they are entitled to
a credit or refund for the tax paid by a Portfolio. If a Portfolio fails to
qualify as a regulated investment company, the Portfolio would be subject to
federal, and possibly state, corporate taxes on its taxable income and gains,
and distributions to you would be taxed as qualified dividend income to the
extent of such Portfolio's earnings and profits.

In order to qualify as a regulated investment company for federal income
tax purposes, a Portfolio must meet certain specific requirements, including:

(i) The Portfolio must maintain a diversified portfolio of securities,
wherein no security, including the securities of a qualified publicly traded
partnership (other than U.S. government securities and securities of other
regulated investment companies) can exceed 25% of the Portfolio's total assets,
and, with respect to 50% of the Portfolio's total assets, no investment (other
than cash and cash items, U.S. government securities and securities of other
regulated investment companies) can exceed 5% of the Portfolio's total assets or
10% of the outstanding voting securities of the issuer;

(ii) The Portfolio must derive at least 90% of its gross income from
dividends, interest, payments with respect to securities loans, gains from the
sale or disposition of stock, securities or foreign currencies, or other income
derived with respect to its business of investing in such stock, securities, or
currencies, and net income derived from an interest in a qualified publicly
traded partnership; and

(iii) The Portfolio must distribute to its shareholders at least 90% of its
investment company taxable income and net tax-exempt income for each of its
fiscal years.

Excise Tax Distribution Requirement

To avoid federal excise taxes, the Code requires a Portfolio to distribute
to you by December 31 of each year, at a minimum, the following amounts: 98% of
its taxable ordinary income earned during the calendar year; 98% of its capital
gain net income earned during the twelve-month period ending November 30; and
100% of any undistributed amounts from the prior year. Each Portfolio intends to
declare and pay these distributions in December (or to pay them in January, in
which case you must treat them as received in December) but can give no
assurances that its distributions will be sufficient to eliminate all taxes.

Sales, Exchanges and Redemption of Portfolio Shares

In general. If you are a taxable investor, sales, exchanges and redemptions
(including redemptions in kind) are taxable transactions for federal and state
income tax purposes. If you redeem your Portfolio shares, the Internal Revenue
Service (the "IRS") requires you to report any gain or loss on your redemption.
If you held your shares as a capital asset, the gain or loss that you realize
will be capital gain or loss and will be long-term or short-term, generally
depending on how long you have held your shares.

Redemptions at a loss within six months of purchase. Any loss incurred on a
redemption of shares held for six months or less will be treated as long-term
capital loss to the extent of any long-term capital gain distributed to you by a
Portfolio on those shares.

Wash sales. All or a portion of any loss that you realize on a redemption
of your Portfolio shares will be disallowed to the extent that you buy other
shares in a Portfolio (through reinvestment of dividends or otherwise) within 30
days before or after your share redemption. Any loss disallowed under these
rules will be added to your tax basis in the new shares.

U.S. Government Obligations

To the extent a Portfolio invests in certain U.S. government obligations,
dividends paid by the Portfolio to shareholders that are derived from interest
on these obligations should be exempt from state and local personal income
taxes, subject in some states to minimum investment or reporting requirements
that must be met by the Portfolio. The income on portfolio investments in
certain securities, such as repurchase agreements, commercial paper and federal
agency-backed obligations (e.g., Government National Mortgage Association (GNMA)
or Federal National Mortgage Association (FNMA) securities), generally does not
qualify for tax-free treatment. The rules on exclusion of this income are
different for corporate shareholders.

Qualified Dividend Income for Individuals

For individual shareholders, a portion of the dividends paid by a Portfolio
may be qualified dividends eligible for taxation at long-term capital gain
rates. This reduced rate generally is available for dividends paid by a
Portfolio out of dividends earned on the Portfolio's investment in stocks of
domestic corporations and qualified foreign corporations.

Both a Portfolio and the investor must meet certain holding period
requirements to qualify Portfolio dividends for this treatment. Specifically, a
Portfolio must hold the stock for at least 61 days during the 121-day period
beginning 60 days before the stock becomes ex-dividend. Similarly, investors
must hold their Portfolio shares for at least 61 days during the 121-day period
beginning 60 days before the Portfolio distribution goes ex-dividend. The
ex-dividend date is the first date following the declaration of a dividend on
which the purchaser of stock is not entitled to receive the dividend payment.
When counting the number of days you held your Portfolio shares, include the day
you sold your shares but not the day you acquired these shares.

While the income received in the form of a qualified dividend is taxed at
the same rates as long-term capital gains, such income will not be considered as
a long-term capital gain for other federal income tax purposes. For example, you
will not be allowed to offset your long-term capital losses against qualified
dividend income on your federal income tax return. Any qualified dividend income
that you elect to be taxed at these reduced rates also cannot be used as
investment income in determining your allowable investment interest expense. For
other limitations on the amount of or use of qualified dividend income on your
income tax return, please contact your personal tax advisor.

After the close of its fiscal year, a Portfolio will designate the portion
of its ordinary dividend income that meets the definition of qualified dividend
income taxable at reduced rates. If 95% or more of a Portfolio's income is from
qualified sources, it will be allowed to designate 100% of its ordinary income
distributions as qualified dividend income.

Dividends-Received Deduction for Corporations

For corporate shareholders, a portion of the dividends paid by a Portfolio
may qualify for the dividends-received deduction. The portion of dividends paid
by a Portfolio that so qualifies will be designated each year in a notice mailed
to a Portfolio's shareholders, and cannot exceed the gross amount of dividends
received by a Portfolio from domestic (U.S.) corporations that would have
qualified for the dividends-received deduction in the hands of a Portfolio if
the Portfolio was a regular corporation. Dividends paid by a Portfolio from
interest on debt securities or dividends earned on portfolio securities of
non-U.S. issuers are not expected to qualify for the corporate
dividends-received deduction. Because the International Portfolio's income is
derived primarily from foreign issuers, none or only a small amount of its
distributions are expected to qualify for the corporate dividends-received
deduction.

The availability of the dividends-received deduction is subject to certain
holding period and debt financing restrictions imposed under the Code on the
corporation claiming the deduction. The amount that a Portfolio may designate as
eligible for the dividends-received deduction will be reduced or eliminated if
the shares on which the dividends earned by the Portfolio were debt-financed or
held by the Portfolio for less than a minimum period of time, generally 46 days
during a 91-day period beginning 45 days before the stock becomes ex-dividend.
Similarly, if your Portfolio shares are debt-financed or held by you for less
than a 46-day period then the dividends-received deduction for Portfolio
dividends on your shares may also be reduced or eliminated. Even if designated
as dividends eligible for the dividends-received deduction, all dividends
(including any deducted portion) must be included in your alternative minimum
taxable income calculation.

Complex Securities

Each Portfolio may invest in complex securities and such investments may be
subject to numerous special and complicated tax rules. These rules could affect
whether gains or losses recognized by a Portfolio are treated as ordinary income
or capital gain, accelerate the recognition of income to the Portfolio, defer
the Portfolio's ability to recognize losses, and subject the Portfolio to U.S.
federal income tax on income from certain of the Portfolio's foreign
investments. In turn, these rules may affect the amount, timing and/or tax
character of a Portfolio's income and, in turn, of the income distributed to
you.

Derivatives. Each Portfolio is permitted to invest in certain options,
futures and foreign currency contracts. If a Portfolio makes these investments,
it could be required to mark-to-market these contracts and realize any
unrealized gains and losses at its fiscal year end even though it continues to
hold the contracts. Under these rules, gains or losses on the contracts
generally would be treated as 60% long-term and 40% short-term gains or losses,
but gains or losses on certain foreign currency contracts would be treated as
ordinary income or losses. In determining its net income for excise tax
purposes, a Portfolio also would be required to mark-to-market these contracts
annually as of November 30 (for capital gain net income and ordinary income
arising from certain foreign currency contracts), and to realize and distribute
any resulting income and gains.

Securities lending. A Portfolio's entry into securities lending
transactions may cause the replacement income earned on the loaned securities to
fall outside of the definition of qualified dividend income. This replacement
income generally will not be eligible for reduced rates of taxation on qualified
dividend income and, to the extent that debt securities are loaned, will
generally not qualify as qualified interest income for foreign withholding tax
purposes.

Tax straddles. A Portfolio's investment in options, futures and foreign
currency contracts in connection with certain hedging transactions could cause
the Portfolio to hold offsetting positions in securities. If a Portfolio's risk
of loss with respect to specific securities in its portfolio is substantially
diminished by the fact that it holds other securities, the Portfolio could be
deemed to have entered into a tax "straddle" or to hold a "successor position"
that would require any loss realized by it to be deferred for tax purposes.

Investments in securities of uncertain tax character. A Portfolio may
invest in securities the U.S. Federal income tax treatment of which may not be
clear or may be subject to recharacterization by the IRS. To the extent the tax
treatment of such securities or the income from such securities differs from the
tax treatment expected by a Portfolio, it could affect the timing or character
of income recognized by a Portfolio, requiring a Portfolio to purchase or sell
securities, or otherwise change its portfolio, in order to comply with the tax
rules applicable to regulated investment companies under the Code.

Backup Withholding

By law, a Portfolio must withhold a portion of your taxable dividends and
sales proceeds unless you:

o provide your correct social security or taxpayer identification
number,
o certify that this number is correct,
o certify that you are not subject to backup withholding, and
o certify that you are a U.S. person (including a U.S. resident alien).

A Portfolio also must withhold if the IRS instructs it to do so. When
withholding is required, the amount will be 28% of any dividends or proceeds
paid. The special U.S. tax certification requirements applicable to non-U.S.
investors are described under the "Non-U.S. Investors" heading below.

Non-U.S. Investors

Non-U.S. investors (shareholders who, as to the United States, are a
nonresident alien individual, foreign trust or estate, foreign corporation, or
foreign partnership) may be subject to U.S. withholding and estate tax and are
subject to special U.S. tax certification requirements. Non-U.S. investors
should consult their tax advisors about the applicability of U.S. tax
withholding and the use of the appropriate forms to certify their status.

In general. The United States imposes a flat 30% withholding tax (or a
withholding tax at a lower treaty rate) on U.S. source dividends, including on
income dividends paid to you by a Portfolio, subject to certain exemptions for
dividends designated as capital gain dividends, short-term capital gain
dividends and interest-related dividends as described below. However,
notwithstanding such exemptions from U.S. withholding at the source, any
dividends and distributions of income and capital gains, including the proceeds
from the sale of your Portfolio shares, 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.

Capital gain dividends & short-term capital gain dividends. In general,
capital gain dividends paid by a Portfolio from either long-term or short-term
capital gains (other than gain realized on disposition of U.S. real property
interests) are not subject to U.S. withholding tax unless you are a nonresident
alien individual present in the United States for a period or periods
aggregating 183 days or more during the taxable year.

Interest-related dividends. Also, interest-related dividends paid by a
Portfolio from qualified interest income are not subject to U.S. withholding
tax. "Qualified interest income" includes, in general, U.S. source (1) bank
deposit interest, (2) short-term original discount, and (3) interest (including
original issue discount, market discount, or acquisition discount) on an
obligation which is in registered form, unless it is earned on an obligation
issued by a corporation or partnership in which a Portfolio is a 10-percent
shareholder or is contingent interest, and (4) any interest-related dividend
from another regulated investment company. On any payment date, the amount of an
income dividend that is designated by a Portfolio as an interest-related
dividend may be more or less than the amount that is so qualified. This is
because the designation is based on an estimate of a Portfolio's qualified
interest income for its entire fiscal year, which can only be determined with
exactness at fiscal year end. As a consequence, a Portfolio may over withhold a
small amount of U.S. tax from a dividend payment. In this case, the non-U.S.
investor's only recourse may be either to forgo recovery of the excess
withholding, or to file a United States nonresident income tax return to recover
the excess withholding.

Further limitations on tax reporting for interest-related dividends and
short-term capital gain dividends for non-U.S. investors; sunset rule. It may
not be practical in every case for a Portfolio to designate, and a Portfolio
reserves the right in these cases to not designate, small amounts of
interest-related or short-term capital gain dividends. Additionally, a
Portfolio's designation of interest-related or short-term capital gain dividends
may not be passed through to shareholders by intermediaries who have assumed tax
reporting responsibilities for this income in managed or omnibus accounts due to
systems limitations or operational constraints. The exemption from withholding
for short-term capital gain dividends and interest-related dividends paid by a
Portfolio is effective for dividends paid with respect to taxable years of the
Portfolio beginning after December 31, 2004 and before January 1, 2008 unless
such exemptions are extended or made permanent.

Ordinary dividends; effectively connected income. Ordinary dividends paid
by a Portfolio to non-U.S. investors on the income earned on portfolio
investments in (i) the stock of domestic and foreign corporations, and (ii) the
debt of foreign issuers continue to be subject to U.S. withholding tax. If you
hold your Portfolio shares in connection with a U.S. trade or business, your
income and gains will be considered effectively connected income and taxed in
the U.S. on a net basis, in which case you may be required to file a nonresident
U.S. income tax return.

U.S tax certification rules. Special U.S. tax certification requirements
apply to non-U.S. shareholders both to avoid U.S. back up withholding imposed at
a rate of 28% and to obtain the benefits of any treaty between the United States
and the shareholder's country of residence. In general, a non-U.S. shareholder
must provide a Form W-8 BEN (or other applicable Form W-8) to establish that you
are not a U.S. person, to claim that you are the beneficial owner of the income
and, if applicable, to claim a reduced rate of, or exemption from, withholding
as a resident of a country with which the United States has an income tax
treaty. A Form W-8BEN provided without a U.S. taxpayer identification number
will remain in effect for a period beginning on the date signed and ending on
the last day of the third succeeding calendar year unless an earlier change of
circumstances makes the information on the form incorrect.

U.S. estate tax. An individual who, at the time of death, is a Non-U.S.
shareholder will nevertheless be subject to U.S. federal estate tax with respect
to shares at the graduated rates applicable to U.S. citizens and residents,
unless a treaty exception applies. In the absence of a treaty, there is a
$13,000 statutory estate tax credit. A partial exemption from U.S. estate tax
may apply to Portfolio shares held by the estate of a nonresident decedent. The
amount treated as exempt is based upon the proportion of the assets held by a
Portfolio at the end of the quarter immediately preceding the decedent's death
that are debt obligations, deposits, or other property that generally would be
treated as situated outside the United States if held directly by the estate.
This provision applies to decedents dying after December 31, 2004 and before
January 1, 2008, unless such provision is extended or made permanent. Transfers
by gift of shares of a Portfolio by a non-U.S. shareholder who is a nonresident
alien individual will not be subject to U.S. federal gift tax. The tax
consequences to a non-U.S. shareholder entitled to claim the benefits of an
applicable tax treaty may be different from those described herein. Non-U.S.
shareholders are urged to consult their own tax advisers with respect to the
particular tax consequences to them of an investment in a Portfolio, including
the applicability of foreign tax.

Effect of Future Legislation; Local Tax Considerations

The foregoing general discussion of U.S. federal income tax consequences is
based on the Code and the regulations issued thereunder as in effect on the date
of this Statement of Additional Information. Future legislative or
administrative changes or court decisions may significantly change the
conclusions expressed herein, and any such changes or decisions may have a
retroactive effect with respect to the transactions contemplated herein. Rules
of state and local taxation of ordinary income, qualified dividend income and
capital gain dividends may differ from the rules for U.S. federal income
taxation described above. Distributions may also be subject to additional state,
local and foreign taxes depending on each shareholder's particular situation.
Non-U.S. shareholders may be subject to U.S. tax rules that differ significantly
from those summarized above. Shareholders are urged to consult their tax
advisers as to the consequences of these and other state and local tax rules
affecting investment in a Portfolio.

This discussion of "Taxation of the Portfolios" is not intended or written
to be used as tax advice and does not purport to deal with all federal tax
consequences applicable to all categories of investors, some of which may be
subject to special rules. You should consult your own tax advisor regarding your
particular circumstances before making an investment in a Portfolio.

PROXY VOTING POLICIES

The Board of Directors of the Fund has delegated the authority to vote
proxies for the portfolio securities held by the Portfolios to the Advisor in
accordance with the Proxy Voting Policies and Procedures (the "Voting Policies")
and Proxy Voting Guidelines ("Voting Guidelines") adopted by the Advisor.

The Investment Committee of the Advisor is generally responsible for
overseeing the Advisor's proxy voting process. The Investment Committee has
formed a Corporate Governance Committee composed of certain officers, directors
and other personnel of the Advisor and has delegated to its members authority
to: (i) oversee the voting of proxies; (ii) make determinations as to how to
vote certain specific proxies; and (iii) verify the on-going compliance with the
Voting Policies. The Corporate Governance Committee may designate one or more of
its members to oversee specific, ongoing compliance with respect to the Voting
Policies and may designate other personnel of the Advisor to vote proxies on
behalf of the Portfolios, including all authorized traders of the Advisor.

The Advisor votes (or refrains from voting) proxies in a manner consistent
with the best interests of a Portfolio as understood by the Advisor at the time
of the vote. Generally, the Advisor analyzes proxy statements on behalf of a
Portfolio in accordance with the Voting Policies and the Voting Guidelines. Most
proxies that the Advisor receives will be voted in accordance with the Voting
Guidelines. Since most proxies are voted in accordance with the Voting
Guidelines, it normally will not be necessary for the Advisor to make an actual
determination of how to vote a particular proxy, thereby largely eliminating
conflicts of interest for the Advisor during the proxy voting process. However,
the Proxy Policies do address the procedures to be followed if a conflict of
interest arises between the interests of a Portfolio, and the interests of the
Advisor or its affiliates. If the Corporate Governance Committee member has
actual knowledge of a conflict of interest and recommends a vote contrary to the
Voting Guidelines, the Advisor, prior to voting, will fully disclose the
conflict to the Board of Directors of the Fund, or an authorized committee of
the Board, and vote the proxy in accordance with the direction of the Board or
its authorized committee.

The Advisor will usually vote proxies in accordance with the Voting
Guidelines. The Voting Guidelines provide a framework for analysis and
decision-making, however, the Voting Guidelines do not address all potential
issues. In order to be able to address all the relevant facts and circumstances
related to a proxy vote, the Advisor reserves the right to vote counter to the
Voting Guidelines if, after a review of the matter, the Advisor believes that
the best interests of a Portfolio would be served by such a vote. In such a
circumstance, the analysis will be documented in writing and periodically
presented to the Corporate Governance Committee. To the extent that the Voting
Guidelines do not cover potential voting issues, the Advisor will vote on such
issues in a manner that is consistent with the spirit of the Voting Guidelines
and that the Advisor believes would be in the best interests of a Portfolio.

Examples of some of the Voting Guidelines are described below. Under the
Voting Guidelines, proxies will usually be voted for: (i) the ratification of
independent auditors; (ii) the elimination of anti-takeover measures; and (iii)
re-incorporation when the economic factors outweigh any negative governance
changes. Pursuant to the Voting Guidelines, proxies will usually be voted
against (i) the institution of anti-takeover measures (such as the institution
of classified boards of directors and the creation of super majority
provisions), and (ii) proposals authorizing the creation of new classes of
preferred stock with unspecified voting, conversion, dividend distribution and
other rights. The Voting Guidelines also provide that certain proposals will be
considered on a case-by-case basis, including: (i) mergers and acquisitions,
which will be assessed to determine whether the transaction enhances shareholder
value; (ii) proposals with respect to management compensation plans; (iii)
proposals increasing the authorized common stock of a company; and (iv)
proposals with respect to the composition of a company's Board of Directors. The
Advisor may, but will not ordinarily, take social concerns into account in
voting proxies with respect to securities held by a Portfolio.

The Advisor votes (or refrains from voting) proxies in a manner that the
Advisor determines is in the best interests of a Portfolio and which seeks to
maximize the value of the Portfolio's investments. In some cases, the Advisor
may determine that it is in the best interests of a Portfolio to refrain from
exercising proxy voting rights. The Advisor may determine that voting is not in
the best interest of a Portfolio and refrain from voting if the costs, including
the opportunity costs, of voting would, in the view of the Advisor, exceed the
expected benefits of voting. For securities on loan, the Advisor will balance
the revenue-producing value of loans against the difficult-to-assess value of
casting votes. It is the Advisor's belief that the expected value of casting a
vote generally will be less than the securities lending income, either because
the votes will not have significant economic consequences or because the outcome
of the vote would not be affected by the Advisor recalling loaned securities in
order to ensure they are voted. The Advisor does intend to recall securities on
loan if it determines that voting the securities is likely to materially affect
the value of a Portfolio's investment and that it is in the Portfolio's best
interests to do so. In cases where the Advisor does not receive a solicitation
or enough information within a sufficient time (as reasonably determined by the
Advisor) prior to the proxy-voting deadline, the Advisor may be unable to vote.

With respect to non-U.S. securities, it is typically both difficult and
costly to vote proxies due to local restrictions, customs, and other
requirements or restrictions. The Advisor does not vote proxies of non-U.S.
companies if the Advisor determines that the expected economic costs from voting
outweigh the anticipated economic benefit to a Portfolio associated with voting.
The Advisor determines whether to vote proxies of non-U.S. companies on a
portfolio-by-portfolio basis, and generally implements uniform voting procedures
for all proxies of a country. The Advisor periodically reviews voting logistics,
including costs and other voting difficulties, on a portfolio-by-portfolio and
country-by-country basis, in order to determine if there have been any material
changes that would affect the Advisor's decision of whether or not to vote.

The Advisor has retained Institutional Shareholder Services ("ISS"), an
independent third party service provider, to provide certain services with
respect to proxy voting. ISS provides information on shareholder meeting dates
and proxy materials; translates proxy materials printed in a foreign language;
provides research on proxy proposals and voting recommendations in accordance
with the Voting Guidelines; effects votes on behalf of a Portfolio; and provides
reports concerning the proxies voted. Although the Advisor may consider the
recommendations of ISS on proxy issues, the Advisor remains ultimately
responsible for all proxy voting decisions.

Information regarding how a Portfolio voted proxies related to its
portfolio securities during the 12 month period ended June 30 of each year is
available, no later than August 31 of each year, without charge, (i) upon
request, by calling collect: (310) 395-8005, or (ii) on the Advisor's web site
at http://www.dfaus.com, and (iii) on the Commission's web site at
http://www.sec.gov.

DISCLOSURE OF PORTFOLIO HOLDINGS

The Advisor and the Board of Directors of the Fund have adopted a policy
(the "Policy") to govern disclosure of the portfolio holdings of each Portfolio
("Holdings Information"), and to prevent the misuse of material non-public
Holdings Information. The Advisor has determined that the Policy and its
procedures: (1) are reasonably designed to ensure that disclosure of Holdings
Information is in the best interests of the shareholders of a Portfolio, and (2)
appropriately address the potential for material conflicts of interest.

Disclosure of Holdings Information as Required by Applicable Law. Holdings
Information (whether a partial listing of portfolio holdings or a complete
listing of portfolio holdings) shall be disclosed to any person as required by
applicable law, rules, and regulations.

Online Disclosure of Portfolio Holdings Information. Each Portfolio
generally discloses up to its twenty-five largest portfolio holdings and the
percentages that each of these largest portfolio holdings represent of the
Portfolio's total assets ("largest holdings"), as of the most recent month-end,
online at the Advisor's public web site, http://www.dfaus.com, within twenty
days after the end of each month. This online disclosure may also include
information regarding a Portfolio's industry allocations. Each Portfolio
generally discloses its complete Holdings Information (other than cash and cash
equivalents), as of month-end, online at the Advisor's public web site,
http://www.dfaus.com, three months following the month-end.

Disclosure of Holdings Information to Recipients. Each of the Advisor's
Chairman, Director of Institutional Services, Head of Portfolio Management and
Trading and General Counsel (together, the "Designated Persons") may authorize
disclosing non-public Holdings Information more frequently or at different
periods than as described above solely to those financial advisors, registered
accountholders, authorized consultants, authorized custodians, or third-party
data service providers (each a "Recipient") who (i) specifically request the
more current non-public Holdings Information, and (ii) execute a Use and
Nondisclosure Agreement (each a "Nondisclosure Agreement"). Each Nondisclosure
Agreement subjects the Recipient to a duty of confidentiality with respect to
the non-public Holdings Information, and prohibits the Recipient from trading
based on the non-public Holdings Information. Any non-public Holdings
Information that is disclosed shall not include any material information about
the Portfolio's trading strategies or pending portfolio transactions. The
non-public Holdings Information provided to a Recipient under a Nondisclosure
Agreement, unless indicated otherwise, is not subject to a time delay before
dissemination.

As of the date of this SAI, the Advisor and the Portfolios had ongoing
arrangements with the following Recipients to make available non-public Holdings
Information:

Recipient Portfolios Business Purpose Frequency

Environmental Impact Vendor Both Portfolios Environmental Impact Quarterly
Analysis

In addition, certain employees of the Advisor and its subsidiaries receive
Holdings Information on a quarterly, monthly, or daily basis, or upon request,
in order to perform their business functions. None of the Portfolios, the
Advisor, or any other party receives any compensation in connection with these
arrangements.

The Policy includes the following procedures to ensure that disclosure of
Holdings Information is in the best interests of shareholders, and to address
any conflicts between the interests of shareholders, on the one hand, and the
interests of the Advisor, DFAS, or any affiliated person of the Fund, the
Advisor, or DFAS, on the other. In order to protect the interests of
shareholders and each Portfolio, and to ensure no adverse effect on shareholders
in the limited circumstances where a Designated Person is considering making
non-public Holdings Information available to a Recipient, the Advisor's Director
of Institutional Services and the Chief Compliance Officer will consider any
conflicts of interest. If the Chief Compliance Officer, following appropriate
due diligence, determines that: (1) a Portfolio has a legitimate business
purpose for providing the non-public Holdings Information to a Recipient, and
(2) disclosure of non-public Holdings Information to the Recipient would be in
the best interests of shareholders and will not adversely affect the
shareholders, then the Chief Compliance Officer may approve the proposed
disclosure.

The Chief Compliance Officer documents all disclosures of non-public
Holdings Information (including the legitimate business purpose for the
disclosure), and periodically reports to the Board on such arrangements. The
Chief Compliance Officer also is responsible for ongoing monitoring of the
distribution and use of non-public Holdings Information. Such arrangements are
reviewed by the Chief Compliance Officer on an annual basis. Specifically, the
Chief Compliance Officer requests an annual certification from each Recipient
that the Recipient has complied with all terms contained in the Nondisclosure
Agreement. Recipients who fail to provide the requested certifications are
prohibited from receiving non-public Holdings Information.

The Board exercises continuing oversight of the disclosure of Holdings
Information by: (1) overseeing the implementation and enforcement of the Policy
by the Chief Compliance Officer of the Advisor and of the Fund; (2) considering
reports and recommendations by the Chief Compliance Officer concerning the
implementation of the Policy and any material compliance matters that may arise
in connection with the Policy; and (3) considering whether to approve or ratify
any amendments to the Policy. The Advisor and the Board reserve the right to
amend the Policy at any time, and from time to time without prior notice, in
their sole discretion.

Prohibitions on Disclosure of Portfolio Holdings and Receipt of
Compensation. No person is authorized to disclose Holdings Information or other
investment positions (whether online at http://www.dfaus.com, in writing, by
fax, by e-mail, orally, or by other means) except in accordance with the Policy.
In addition, no person is authorized to make disclosure pursuant to the Policy
if such disclosure is otherwise in violation of the antifraud provisions of the
federal securities laws.

The Policy prohibits the Portfolios, the Advisor, or an affiliate thereof
from receiving any compensation or other consideration of any type for the
purpose of obtaining disclosure of non-public Holdings Information or other
investment positions. "Consideration" includes any agreement to maintain assets
in a Portfolio or in other investment companies or accounts managed by the
Advisor or by any affiliated person of the Advisor.

The Policy and its procedures are intended to provide useful information
concerning the Portfolios to existing and prospective shareholders, while at the
same time preventing the improper use of Holdings Information. However, there
can be no assurance that the furnishing of any Holdings Information is not
susceptible to inappropriate uses, particularly in the hands of sophisticated
investors, or that the Holdings Information will not in fact be misused in other
ways, beyond the control of the Advisor.

FINANCIAL STATEMENTS

PricewaterhouseCoopers LLP, Two Commerce Square, Suite 1700, 2001 Market
Street, Philadelphia, PA 19103-7042, is the Fund's independent registered public
accounting firm. It audits the Fund's annual financial statements. Because the
Portfolios had not commenced operations as of November 30, 2006, the annual
reports of the Fund for the fiscal year ended November 30, 2006 do not contain
any data regarding the Portfolios.

PERFORMANCE DATA

Each Portfolio may compare its investment performance to appropriate market
and mutual fund indices and investments for which reliable performance data is
available. Such indices are generally unmanaged and are prepared by entities and
organizations that track the performance of investment companies or investment
advisors. Unmanaged indices often do not reflect deductions for administrative
and management costs and expenses. The performance of a Portfolio may also be
compared in publications to averages, performance rankings, or other information
prepared by recognized mutual fund statistical services. Any performance
information, whether related to a Portfolio or to the Advisor, should be
considered in light of the Portfolio's investment objectives and policies,
characteristics and the quality of the portfolio and market conditions during
the time period indicated and should not be considered to be representative of
what may be achieved in the future.

PORTFOLIO CHARACTERISTICS AND POLICIES

The following information supplements the information set forth in the
Prospectus of the Portfolio. Capitalized terms not otherwise defined in this SAI
have the meaning assigned to them in the Prospectus.

Dimensional Fund Advisors LP (the "Advisor") serves as investment advisor
to the Portfolio. The Advisor is organized as a Delaware limited partnership and
is controlled and operated by its general partner, Delaware Holdings Inc., a
Delaware corporation. Prior to November 3, 2006, the Advisor was named
Dimensional Fund Advisors Inc. and was organized as a Delaware corporation.

The Portfolio is diversified under the federal securities laws and
regulations.

BROKERAGE TRANSACTIONS

The Portfolio acquires and sells securities on a net basis with dealers
that are major market makers in such securities. The Investment Committee of the
Advisor selects dealers on the basis of their size, market-making, and credit
analysis ability. When executing portfolio transactions for the Portfolio, the
Advisor seeks to obtain the most favorable price for the securities being traded
among the dealers with whom the Portfolio effects transactions.

Portfolio transactions will be placed with a view to receiving the best
price and execution. The Portfolio will seek to acquire and dispose of
securities in a manner, which would cause as little fluctuation in the market
prices of stocks being purchased or sold as possible in light of the size of the
transactions being effected, and brokers will be selected with this goal in
view. The Advisor monitors the performance of brokers that effect transactions
for the Portfolio to determine the effect that the brokers' trading has on the
market prices of the securities in which the Portfolio invests. The Advisor also
checks the rate of commission being paid by the Portfolio to its brokers to
ascertain that the rates are competitive with those charged by other brokers for
similar services.

Transactions also may be placed with brokers who provide the Advisor with
investment research, such as reports concerning individual issuers, industries,
and general economic and financial trends, and other research services. The
Investment Advisory Agreement of the Portfolio permits the Advisor knowingly to
pay commissions on these transactions that are greater than another broker,
dealer, or exchange member might charge if the Advisor, in good faith,
determines that the commissions paid are reasonable in relation to the research
or brokerage services provided by the broker or dealer when viewed in terms of
either a particular transaction or the Advisor's overall responsibilities to the
accounts under the Advisor's management. Research services furnished by brokers
through whom securities transactions are effected may be used by the Advisor in
servicing all of its accounts and not all such services may be used by the
Advisor with respect to the Portfolio.

Subject to obtaining best price and execution, transactions may be placed
with brokers that have assisted in the sale of Fund shares. The Advisor,
however, pursuant to policies and procedures approved by the Board of Directors
of the Fund, is prohibited from selecting brokers and dealers to effect the
securities transactions for the Portfolio based (in whole or in part) on a
broker's or dealer's promotion or sale of shares issued by the Portfolio or any
other registered investment companies.

Because the Portfolio had not commenced investment operations prior to the
date of this SAI, the Portfolio has not incurred any brokerage commissions that
are required to be reported.

INVESTMENT LIMITATIONS

The Portfolio has adopted certain limitations that may not be changed with
respect to the Portfolio without the approval of a majority of the outstanding
voting securities of the Portfolio. A "majority" is defined as the lesser of:
(1) at least 67% of the voting securities of the Portfolio (to be affected by
the proposed change) present at a meeting, if the holders of more than 50% of
the outstanding voting securities of the Portfolio are present or represented by
proxy, or (2) more than 50% of the outstanding voting securities of such
Portfolio.

The Portfolio will not:

(1) purchase or sell real estate, unless acquired as a result of ownership of
securities or other instruments and provided that this restriction does not
prevent the Portfolio from investing in issuers that invest, deal, or
otherwise engage in transactions in real estate or interests therein, or
investing in securities that are secured by real estate or interests
therein;

(2) purchase or sell physical commodities, unless acquired as a result of
ownership of securities or other instruments and provided that this
restriction does not prevent the Portfolio from engaging in transactions
involving futures contracts and options thereon or investing in securities
that are secured by physical commodities;

(3) make loans to other persons, except: (a) through the lending of its
portfolio securities; (b) through the purchase of debt securities, loan
participations and/or engaging in direct corporate loans for investment
purposes in accordance with its investment objective and policies; and (c)
to the extent the entry into a repurchase agreement is deemed to be a loan;

(4) purchase the securities of any one issuer (other than the U.S. government
or any of its agencies or instrumentalities or securities of other
investment companies) if immediately after such investment: (a) more than
5% of the value of the Portfolio's total assets would be invested in such
issuer, or (b) more than 10% of the outstanding voting securities of such
issuer would be owned by the Portfolio, except that up to 25% of the value
of the Portfolio's total assets may be invested without regard to such 5%
and 10% limitations;

(5) borrow money, except that it may: (a) borrow from banks (as defined in the
1940 Act) or other financial institutions in amounts up to 33 1/3% of its
total assets (including the amount borrowed), and (b) to the extent
permitted by applicable law, borrow up to an additional 5% of its total
assets for temporary purposes;

(6) issue senior securities (as such term is defined in Section 18(f) of the
1940 Act), except to the extent permitted under the 1940 Act;

(7) engage in the business of underwriting securities issued by others; and

(8) acquire any securities of companies within one industry if, as a result of
such acquisition, more than 25% of the value of the Portfolio's total
assets would be invested in securities of companies within such industry;
except that the Portfolio shall invest more than 25% of its total assets in
obligations of banks and bank holding companies in the circumstances
described in the Prospectus under "Investments in the Banking Industry" and
as otherwise described under "Portfolio Strategy."

Although not a fundamental policy subject to shareholder approval, the
Portfolio does not intend to invest more than 15% of its net assets in illiquid
securities.

With respect to the investment limitation described in 5(a) above, the
Portfolio will maintain asset coverage of at least 300% (as described in the
1940 Act), inclusive of any amounts borrowed. With respect to the investment
limitation described in 5(b) above, the Portfolio will segregate assets to cover
the amount borrowed by the Portfolio. The Portfolio currently does not intend to
borrow money for investment purposes.

Subject to future regulatory guidance, for purposes of those investment
limitations identified above that are based on total assets, "total assets"
refers to the assets that the Portfolio owns, and does not include assets that
the Portfolio does not own but over which it has effective control. For example,
when applying a percentage investment limitation that is based on total assets,
the Portfolio will exclude from its total assets those assets that represent
collateral received by the Portfolio for its securities lending transactions.

Unless otherwise indicated, all limitations applicable to the Portfolio's
investments apply only at the time that a transaction is undertaken. Any
subsequent change in a rating assigned by any rating service to a security or
change in the percentage of the Portfolio's assets invested in certain
securities or other instruments resulting from market fluctuations or other
changes in the Portfolio's total assets will not require the Portfolio to
dispose of an investment until the Advisor determines that it is practicable to
sell or closeout the investment without undue market or tax consequences. In the
event that ratings services assign different ratings to the same security, the
Advisor will determine which rating the Advisor believes best reflects the
security's quality and risk at that time, which may be the higher of the several
assigned ratings.

FUTURES CONTRACTS

The Portfolio may enter into futures contracts and options on futures
contracts to gain market exposure on the Portfolio's uninvested cash pending
investments in securities and to maintain liquidity to pay redemptions. Futures
contracts provide for the future sale by one party and purchase by another party
of a specified amount of defined securities at a specified future time and at a
specified price. Futures contracts that are standardized as to maturity date and
underlying financial instrument are traded on national futures exchanges. The
Portfolio will be required to make a margin deposit in cash or government
securities with a futures commission merchant (an "FCM") to initiate and
maintain positions in futures contracts. Minimal initial margin requirements are
established by the futures exchanges and FCMs may establish margin requirements
that are higher than the exchange requirements. After a futures contract
position is opened, the value of the contract is marked to market daily. If the
futures contract price changes to the extent that the margin on deposit does not
satisfy margin requirements, payment of additional "variation" margin to be held
by the FCM will be required. Conversely, reduction in the contract value may
reduce the required margin resulting in a repayment of excess margin to the
custodial accounts of the Portfolio. Variation margin payments may be made to
and from the futures broker for as long as the contract remains open. The
Portfolio expects to earn income on its margin deposits. The Portfolio intends
to limit its futures-related investment activity so that other than with respect
to bona fide hedging activity (as defined in Commodity Futures Trading
Commission ("CFTC") General Regulations Section 1.3(z)): (i) the aggregate
initial margin and premiums paid to establish commodity futures and commodity
option contract positions (determined at the time the most recent position was
established) does not exceed 5% of the liquidation value of the Portfolio, after
taking into account unrealized profits and unrealized losses on any such
contracts it has entered into (provided that, in the case of an option that is
in-the-money at the time of purchase, the in-the-money amount may be excluded in
calculating such 5% limitation); or (ii) the aggregate net "notional value"
(i.e., the size of a commodity futures or commodity option contract in contract
units (taking into account any multiplier specified in the contract), multiplied
by the current market price (for a futures contract) or strike price (for an
option contract) of each such unit) of all non-hedge commodity futures and
commodity option contracts that the Portfolio has entered into (determined at
the time the most recent position was established) does not exceed the
liquidation value of the Portfolio, after taking into account unrealized profits
and unrealized losses on any such contracts that the Portfolio has entered into.

Positions in futures contracts may be closed out only on an exchange that
provides a secondary market. However, there can be no assurance that a liquid
secondary market will exist for any particular futures contract at any specific
time. Therefore, it might not be possible to close a futures position and, in
the event of adverse price movements, the Portfolio would continue to be
required to make variation margin deposits. In such circumstances, if the
Portfolio has insufficient cash, the Portfolio might have to sell portfolio
securities to meet daily margin requirements at a time when it might be
disadvantageous to do so. Management intends to minimize the possibility that it
will be unable to close out a futures contract by only entering into futures
that are traded on national futures exchanges and for which there appears to be
a liquid secondary market. Pursuant to published positions of the Commission and
interpretations of the staff of the Commission, the Portfolio (or its
custodians) is required to maintain segregated accounts or to segregate assets
through notations on the books of the custodian, consisting of liquid assets
(or, as permitted under applicable interpretations, enter into offsetting
positions) in connection with the Portfolio's futures contract transactions in
order to cover the Portfolio's obligations with respect to such contracts. These
requirements are designed to limit the amount of leverage the Portfolio may use
by entering into futures transactions.

CASH MANAGEMENT PRACTICES

The Portfolio engages in cash management practices in order to earn income
on uncommitted cash balances. Generally, cash is uncommitted pending investment
in other obligations, payment of redemptions, or in other circumstances where
the Advisor believes liquidity is necessary or desirable. For example, the
Portfolio may make cash investments for temporary defensive purposes during
periods in which market, economic, or political conditions warrant.

The Portfolio may invest cash in short-term repurchase agreements, as well
as affiliated or unaffiliated registered or unregistered, money market funds.

DIRECTORS AND OFFICERS

The Board of Directors of the Fund is responsible for establishing the
Fund's policies and for overseeing the management of the Fund.

member of the Fund's Performance Committee is a disinterested Director. The
Performance Committee regularly reviews and monitors the investment performance
of the Fund's series, including the Portfolio, and reviews the performance of
the Fund's service providers. There were six Performance Committee meetings held
during the fiscal year ended November 30, 2007.

(1) Each officer holds office for an indefinite term at the pleasure of the

qualified.

Because the Portfolio has not been offered prior to the date of this SAI,
Directors and officers as a group own less than 1% of the outstanding shares of
the Portfolio.

SERVICES TO THE PORTFOLIO

Administrative Services

PFPC Inc. ("PFPC"), 301 Bellevue Parkway, Wilmington, DE 19809, serves as
the accounting services, dividend disbursing, and transfer agent for the
Portfolio. The services provided by PFPC are subject to supervision by the
executive officers and the Board of Directors of the Fund and include day-to-day
keeping and maintenance of certain records, calculation of the offering price of
the shares, preparation of reports, liaison with its custodian, and transfer and
dividend disbursing agency services. For the administrative and accounting
services provided by PFPC, the Portfolio pays PFPC annual fees that are
calculated daily and paid monthly according to a fee schedule based on the
aggregate average net assets of the Fund Complex, which includes four registered
investment companies and a group trust. The fee schedule is set forth in the
table below:

The fees charged to the Portfolio under the fee schedule are allocated to the
Portfolio based on the Portfolio's pro rata portion of the aggregate net assets
of the Fund Complex.

The Portfolio also is subject to a monthly base fee of $2,083.

The Portfolio also pays separate fees to PFPC with respect to the services
PFPC provides as transfer agent and dividend disbursing agent.

ADVISORY FEES

David G. Booth and Rex A. Sinquefield, as directors and/or officers of the
Advisor and shareholders of the outstanding stock of the Advisor's general
partner, may be deemed controlling persons of the Advisor. For the services it
provides as investment advisor to the Portfolio, the Advisor is paid a monthly
fee calculated as a percentage of average net assets of the Portfolio. As of the
date of this SAI, the Portfolio had not yet commenced operations, so the
Portfolio has not paid any management fees.

Pursuant to a Fee Waiver and Expense Assumption Agreement for the
Portfolio, the Advisor has agreed to waive all or a portion of its management
fee and to assume the ordinary operating expenses of the Portfolio (excluding
the expenses that the Portfolio incurs indirectly through its investment in
other investment companies) ("Portfolio Expenses") to the extent necessary to
limit the Portfolio Expenses of the Portfolio to 0.25% of the Portfolio's
average net assets on an annualized basis (the "Expense Limitation Amount"). At
any time that the Portfolio Expenses of the Portfolio are less than the
Portfolio's Expense Limitation Amount, 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 Portfolio's annualized
Portfolio Expenses 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. The Fee Waiver and Expense Assumption Agreement will remain
in effect for an initial period until April 1 2009, and then shall continue in
effect from year to year for one-year periods thereafter unless terminated by
the Advisor.

PORTFOLIO MANAGER

In accordance with the team approach used to manage the Portfolio, 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 Portfolio, including
running buy and sell programs based on the parameters established by the
Investment Committee. David A. Plecha, the portfolio manager for the fixed
income portfolios, including the Portfolio, coordinates the efforts of all other
portfolio managers with respect to the day-to-day management of the Portfolio.
Because the Portfolio had not commenced operations prior to the date of this
SAI, Mr. Plecha does not own any shares of the Portfolio.

Description of Compensation Structure

Portfolio managers receive a base salary and bonus. Compensation of a
portfolio manager is determined at the discretion of the Advisor and is based on
a portfolio manager's experience, responsibilities, the perception of the
quality of his or her work efforts, and other subjective factors. The
compensation of portfolio managers is not directly based upon the performance of
the Portfolio or other accounts that the portfolio managers manage. The Advisor
reviews the compensation of each portfolio manager annually and may make
modifications in compensation as the Advisor's Compensation Committee deems
necessary to reflect changes in the market. Each portfolio manager's
compensation consists of the following:

o Base salary. Each portfolio manager is paid a base salary. The Advisor
considers the factors described above to determine each portfolio
manager's base salary.

o Semi-Annual Bonus. Each portfolio manager may receive a semi-annual
bonus. The amount of the bonus paid to each portfolio manager is based
upon the factors described above.

Portfolio managers may be awarded the right to purchase restricted shares
of the Advisor's general partner as determined from time to time by the Board of
Directors of the Advisor or its delegees. Portfolio managers also participate in
benefit and retirement plans and other programs available generally to all
employees.

Other Managed Accounts

In addition to the Portfolio, Mr. Plecha manages: (i) other U.S. registered
investment companies advised or sub-advised by the Advisor; (ii) other pooled
investment vehicles that are not U.S. registered mutual funds; and (iii) other
accounts managed for organizations and individuals. The following table sets
forth information regarding the total accounts for which Mr. Plecha has the
primary responsibility for coordinating the day-to-day management
responsibilities:

Number of Accounts Managed and Total Assets by Category as of November 30, 2006:

o 13 U.S. registered mutual funds with $11,079 million in total assets
under management.
o 7 unregistered pooled investment vehicles with $1,612 million in total
assets under management.
o 7 other accounts with $209 million in total assets under management.

None of the U.S. registered mutual funds, unregistered pooled investment
vehicles, and other accounts managed by the portfolio manager are subject to an
advisory fee that is based on the performance of the respective funds,
investment vehicles, or accounts.

Potential Conflicts of Interest

Actual or apparent conflicts of interest may arise when a portfolio manager
has the primary day-to-day responsibilities with respect to more than one
portfolio and other accounts. Other accounts include registered mutual funds
(other than the Portfolio), other unregistered pooled investment vehicles, and
other accounts managed for organizations and individuals ("Accounts"). An
Account may have similar investment objectives to the Portfolio, or may
purchase, sell, or hold securities that are eligible to be purchased, sold, or
held by the Portfolio. Actual or apparent conflicts of interest include:

o Time Management. The management of multiple portfolios and/or Accounts
may result in a portfolio manager devoting unequal time and attention
to the management of each portfolio and/or Account. The Advisor seeks
to manage such competing interests for the time and attention of
portfolio managers by having portfolio managers focus on a particular
investment discipline. Most Accounts managed by a portfolio manager
are managed using the same investment models that are used in
connection with the management of the portfolios.

o Investment Opportunities. It is possible that, at times, identical
securities will be held by more than one portfolio and/or Account.
However, positions in the same security may vary and the length of
time that any portfolio or Account may choose to hold its investment
in the same security likewise may vary. If a portfolio manager
identifies a limited investment opportunity that may be suitable for
more than one portfolio or Account, a portfolio may not be able to
take full advantage of that opportunity, due to an allocation of
filled purchase or sale orders across all eligible portfolios and
Accounts. To deal with these situations, the Advisor has adopted
procedures for allocating portfolio transactions across multiple
portfolios and Accounts.

o Broker Selection. With respect to securities transactions for the
portfolios, the Advisor determines which broker to use to execute each
order, consistent with the Advisor's duty to seek best execution of
the transaction. However, with respect to certain Accounts (such as
separate accounts), the Advisor may be limited by the client with
respect to the selection of brokers or may be instructed to direct
trades through a particular broker. In these cases, the Advisor or its
affiliates may place separate, non-simultaneous, transactions for a
portfolio and another Account that may temporarily affect the market
price of the security or the execution of the transaction, or both, to
the detriment of the portfolio or the Account.

o Performance-Based Fees. For some Accounts, the Advisor may be
compensated based on the profitability of the Account, such as by a
performance-based management fee. These incentive compensation
structures may create a conflict of interest for the Advisor with
regard to Accounts where the Advisor is paid based on a percentage of
assets because the portfolio manager may have an incentive to allocate
securities preferentially to the Accounts where the Advisor might
share in investment gains.

o Investment in an Account. A portfolio manager or his/her relatives may
invest in an Account that he or she manages and a conflict may arise
where he or she may therefore have an incentive to treat the Account
in which the portfolio manager or his/her relatives invest
preferentially as compared to the Portfolio or other Accounts for
which he or she has portfolio management responsibilities.

GENERAL INFORMATION

The Fund was incorporated under Maryland law on June 15, 1981. Until June
1983, the Fund was named DFA Small Company Fund Inc. The Portfolio described in
this SAI had not commenced operations as of the date of this SAI. .

CODE OF ETHICS

The Fund, the Advisor, and DFAS have adopted a Code of Ethics, under Rule
17j-1 of the 1940 Act, for certain access persons of the Portfolio. The Code is
designed to ensure that access persons act in the interest of the Portfolio, and
its shareholders, with respect to any personal trading of securities. Under the
Code, access persons are generally prohibited from knowingly buying or selling
securities (except for mutual funds, U.S. government securities, and money
market instruments) which are being purchased, sold, or considered for purchase
or sale by the Portfolio unless the access persons' proposed purchases are
approved in advance. The Code also contains certain reporting requirements and
personal securities trading clearance procedures.

SHAREHOLDER RIGHTS

The shares of the Portfolio, when issued and paid for in accordance with
the Portfolio's Prospectus, will be fully paid and non-assessable shares. Each
share of common stock represents an equal proportional interest in the assets
and liabilities of the Portfolio and has identical, non-cumulative voting,
dividend, redemption liquidation, and other rights and preferences as the shares
of the Portfolio.

With respect to matters that require shareholder approval, shareholders are
entitled to vote only with respect to matters that affect the interest of the
portfolio of shares that the shareholders hold, except as otherwise required by
applicable law. If liquidation of the Fund should occur, shareholders would be
entitled to receive, on a per class basis, the assets of the particular
portfolio whose shares they own, as well as a proportionate share of Fund assets
not attributable to any particular portfolio. Ordinarily, the Fund does not
intend to hold annual meetings of shareholders, except as required by the 1940
Act or other applicable law. The Fund's bylaws provide that special meetings of
shareholders shall be called at the written request of shareholders entitled to
cast not less than a majority of the votes entitled to be cast at the meeting. .
Such meeting may be called to consider any matter, including the removal of one
or more directors. Shareholders will receive shareholder communications with
respect to such matters as required by the 1940 Act, including semi-annual and
annual financial statements of the Fund.

PRINCIPAL HOLDERS OF SECURITIES

Because the Portfolio has not been offered prior to the date of this SAI,
no person beneficially owned 5% or more of the outstanding shares of the
Portfolio as of the date of this SAI.

PURCHASE OF SHARES

The following information supplements the information set forth in the
Prospectus under the caption "PURCHASE OF SHARES."

The Fund reserves the right, in its sole discretion, to suspend the
offering of shares of the Portfolio or reject purchase orders when, in the
judgment of management, such suspension or rejection is in the best interest of
the Fund or the Portfolio. Securities accepted in exchange for shares of the
Portfolio will be acquired for investment purposes and will be considered for
sale under the same circumstances as other securities in the Portfolio.

The Fund or its transfer agent may, from time to time, appoint a
sub-transfer agent, such as a broker, for the receipt of purchase and redemption
orders and funds from certain investors. With respect to purchases and
redemptions through a sub-transfer agent, the Fund will be deemed to have
received a purchase or redemption order when the sub-transfer agent receives the
order. Shares of the Portfolio will be priced at the public offering price next
calculated after receipt of the purchase or redemption order by the sub-transfer
agent.

Reimbursement fees may be charged prospectively from time to time based
upon the future experience of the Portfolio, which is currently sold at net
asset value. Any such charges will be described in the Prospectus.

REDEMPTION AND TRANSFER OF SHARES

The following information supplements the information set forth in the
Prospectus under the caption "REDEMPTION OF SHARES."

Shareholders may transfer shares of the Portfolio to another person by
making a written request to the Advisor, who will transmit the request to the
transfer agent. The request should clearly identify the account and number of
shares to be transferred, and include the signature of all registered owners and
all stock certificates, if any, which are subject to the transfer. The signature
on the letter of request, the stock certificate, or any stock power must be
guaranteed in the same manner as described in the Prospectus under "REDEMPTION
OF SHARES." As with redemptions, the written request must be received in good
order before any transfer can be made.

TAXATION OF THE PORTFOLIO

The following is a summary of some of the federal income tax consequences
that may affect the Portfolio. Unless your investment in the Portfolio is
through a retirement plan, you should consider the tax implications of investing
and consult your own tax adviser.

Distributions of Net Investment Income

The Portfolio derives income generally in the form of dividends and
interest on its investments. This income, less expenses incurred in the
operation of the Portfolio, constitutes its net investment income from which
dividends may be paid to you. If you are a taxable investor, any distributions
by the Portfolio from such income (other than qualified dividends) will be
taxable to you at ordinary income tax rates, whether you take them in cash or in
additional shares. A portion of the income dividends paid to shareholders may be
qualified dividends eligible to be taxed at reduced rates.

Distributions of Capital Gain

The Portfolio may realize a capital gain or loss in connection with sales
or other dispositions of its portfolio securities. Distributions derived from
the excess of net short-term capital gain over net long-term capital loss will
be taxable to you as ordinary income. Distributions paid from the excess of net
long-term capital gain over net short-term capital loss will be taxable to you
as long-term capital gain, regardless of how long you have held your shares in a
Portfolio. Any net capital gain of the Portfolio generally will be distributed
once each year, and may be distributed more frequently, if necessary, to reduce
or eliminate excise or income taxes on the Portfolio.

Returns of Capital

If the Portfolio's distributions exceed its taxable income and capital
gains realized during a taxable year, all or a portion of the distributions made
in the same taxable year may be recharacterized as a return of capital to
shareholders. A return of capital distribution generally will not be taxable,
but will reduce each shareholder's cost basis in the Portfolio and result in a
higher reported capital gain or lower reported capital loss when those shares on
which the distribution was received are sold. Any return of capital in excess of
a shareholder's basis, however, is taxable as a capital gain.

Effect of Foreign Withholding Taxes

In general. The Portfolio may be subject to foreign withholding taxes on
income from certain foreign securities. This, in turn, could reduce the
Portfolio's income dividends paid to shareholders.

Pass-through of foreign tax credits. If more than 50% in value of the total
assets of the Portfolio is invested in securities of foreign corporations, the
Portfolio may elect to pass through to its shareholders their pro rata share of
foreign income taxes paid by the Portfolio. If this election is made, Portfolio
may report more taxable income to you than it actually distributes. You will
then be entitled either to deduct your share of these taxes in computing your
taxable income, or to claim a foreign tax credit for these taxes against your
U.S. federal income tax (subject to limitations for certain shareholders). The
Portfolio will provide you with the information necessary to complete your
personal income tax return if it makes this election.

The amount of any foreign tax credits available to you (as a result of the
pass-through to you of your pro rata share of foreign taxes by paid by the
Portfolio) will be reduced if you receive from the Portfolio qualifying
dividends from qualifying foreign corporations that are subject to tax at
reduced rates. Shareholders in these circumstances should talk with their
personal tax advisors about their foreign tax credits and the procedures that
they should follow to claim these credits on their personal income tax returns.

Effect of foreign debt investments on distributions. Most foreign exchange
gains realized on the sale of debt securities are treated as ordinary income by
the Portfolio. Similarly, foreign exchange losses realized on the sale of debt
securities generally are treated as ordinary losses. These gains when
distributed are taxable to you as ordinary income, and any losses reduce the
Portfolio's ordinary income otherwise available for distribution to you. This
treatment could increase or decrease the Portfolio's ordinary income
distributions to you, and may cause some or all of the Portfolio's previously
distributed income to be classified as a return of capital.

Information on the Amount and Tax Character of Distributions.

The Portfolio will inform you of the amount and character of your
distributions at the time they are paid, and will advise you of the tax status
of such distributions for federal income tax purposes shortly after the close of
each calendar year. If you have not held Portfolio shares for a full year, the
Portfolio may designate and distribute to you, as ordinary income, qualified
dividends, or capital gains, and in the case of non-U.S. shareholders the
Portfolio may further designate and distribute as interest-related dividends and
short-term capital gain dividends, a percentage of income that is not equal to
the actual amount of such income earned during the period of your investment in
the Portfolio. Taxable Distributions declared by the Portfolio in December to
shareholders of record in such month, but paid in January, are taxable to you as
if they were paid in December.

Election to be Taxed as a Regulated Investment Company

The Portfolio intends to qualify each year as a regulated investment
company by satisfying certain distribution and asset diversification
requirements under the Internal Revenue Code (the "Code"). As a regulated
investment company, the Portfolio generally pays no federal income tax on the
income and gains it distributes to its shareholders. The Board of Directors
reserves the right not to distribute the Portfolio's net long-term capital gain
or not to maintain the qualification of the Portfolio as a regulated investment
company if it determines such a course of action to be beneficial to
shareholders. If net long-term capital gain is retained, the Portfolio would be
taxed on the gain, and shareholders would be notified that they are entitled to
a credit or refund for the tax paid by the Portfolio. If the Portfolio fails to
qualify as a regulated investment company, the Portfolio would be subject to
federal, and possibly state, corporate taxes on its taxable income and gains,
and distributions to you would be taxed as qualified dividend income to the
extent of such Portfolio's earnings and profits.

In order to qualify as a regulated investment company for federal income
tax purposes, the Portfolio must meet certain specific requirements, including:

(i) The Portfolio must maintain a diversified portfolio of
securities, wherein no security, including the securities of a
qualified publicly traded partnership (other than U.S. government
securities and securities of other regulated investment companies) can
exceed 25% of the Portfolio's total assets, and, with respect to 50%
of the Portfolio's total assets, no investment (other than cash and
cash items, U.S. government securities and securities of other
regulated investment companies) can exceed 5% of the Portfolio's total
assets or 10% of the outstanding voting securities of the issuer;

(ii) The Portfolio must derive at least 90% of its gross income
from dividends, interest, payments with respect to securities loans,
gains from the sale or disposition of stock, securities or foreign
currencies, or other income derived with respect to its business of
investing in such stock, securities, or currencies, and net income
derived from an interest in a qualified publicly traded partnership;
and

(iii) The Portfolio must distribute to its shareholders at least
90% of its investment company taxable income and net tax-exempt income
for each of its fiscal years.

Excise Tax Distribution Requirement

To avoid federal excise taxes, the Code requires the Portfolio to
distribute to you by December 31 of each year, at a minimum, the following
amounts: 98% of its taxable ordinary income earned during the calendar year; 98%
of its capital gain net income earned during the twelve-month period ending
November 30; and 100% of any undistributed amounts from the prior year. The
Portfolio intends to declare and pay these distributions in December (or to pay
them in January, in which case you must treat them as received in December) but
can give no assurances that its distributions will be sufficient to eliminate
all taxes.

Sales, Exchanges and Redemption of Portfolio Shares

Wash sales. All or a portion of any loss that you realize on a redemption
of your Portfolio shares will be disallowed to the extent that you buy other
shares in the Portfolio (through reinvestment of dividends or otherwise) within
30 days before or after your share redemption. Any loss disallowed under these
rules will be added to your tax basis in the new shares.

U.S. Government Obligations

To the extent the Portfolio invests in certain U.S. government obligations,
dividends paid by the Portfolio to shareholders that are derived from interest
on these obligations should be exempt from state and local personal income
taxes, subject in some states to minimum investment or reporting requirements
that must be met by the Portfolio. The income on portfolio investments in
certain securities, such as repurchase agreements, commercial paper and federal
agency-backed obligations (e.g., Government National Mortgage Association (GNMA)
or Federal National Mortgage Association (FNMA) securities), generally does not
qualify for tax-free treatment. The rules on exclusion of this income are
different for corporate shareholders.

Qualified Dividend Income for Individuals

For individual shareholders, a portion of the dividends paid by the
Portfolio may be qualified dividends eligible for taxation at long-term capital
gain rates. This reduced rate generally is available for dividends paid by the
Portfolio out of dividends earned on the Portfolio's investment in stocks of
domestic corporations and qualified foreign corporations.

Both the Portfolio and the investor must meet certain holding period
requirements to qualify Portfolio dividends for this treatment. Specifically,
the Portfolio must hold the stock for at least 61 days during the 121-day period
beginning 60 days before the stock becomes ex-dividend. Similarly, investors
must hold their Portfolio shares for at least 61 days during the 121-day period
beginning 60 days before the Portfolio distribution goes ex-dividend. The
ex-dividend date is the first date following the declaration of a dividend on
which the purchaser of stock is not entitled to receive the dividend payment.
When counting the number of days you held your Portfolio shares, include the day
you sold your shares but not the day you acquired these shares.

After the close of its fiscal year, the Portfolio will designate the
portion of its ordinary dividend income that meets the definition of qualified
dividend income taxable at reduced rates. If 95% or more of the Portfolio's
income is from qualified sources, it will be allowed to designate 100% of its
ordinary income distributions as qualified dividend income.

Dividends-Received Deduction for Corporations

For corporate shareholders, a portion of the dividends paid by the
Portfolio may qualify for the dividends-received deduction. The portion of
dividends paid by the Portfolio that so qualifies will be designated each year
in a notice mailed to the Portfolio's shareholders, and cannot exceed the gross
amount of dividends received by the Portfolio from domestic (U.S.) corporations
that would have qualified for the dividends-received deduction in the hands of
the Portfolio if the Portfolio was a regular corporation. Dividends paid by the
Portfolio from interest on debt securities or dividends earned on portfolio
securities of non-U.S. issuers are not expected to qualify for the corporate
dividends-received deduction.

The availability of the dividends-received deduction is subject to certain
holding period and debt financing restrictions imposed under the Code on the
corporation claiming the deduction. The amount that the Portfolio may designate
as eligible for the dividends-received deduction will be reduced or eliminated
if the shares on which the dividends earned by the Portfolio were debt-financed
or held by the Portfolio for less than a minimum period of time, generally 46
days during a 91-day period beginning 45 days before the stock becomes
ex-dividend. Similarly, if your Portfolio shares are debt-financed or held by
you for less than a 46-day period then the dividends-received deduction for
Portfolio dividends on your shares may also be reduced or eliminated. Even if
designated as dividends eligible for the dividends-received deduction, all
dividends (including any deducted portion) must be included in your alternative
minimum taxable income calculation.

Complex Securities

Each Portfolio may invest in complex securities and such investments may be
subject to numerous special and complicated tax rules. These rules could affect
whether gains or losses recognized by the Portfolio are treated as ordinary
income or capital gain, accelerate the recognition of income to the Portfolio,
defer the Portfolio's ability to recognize losses, and subject the Portfolio to
U.S. federal income tax on income from certain of the Portfolio's foreign
investments. In turn, these rules may affect the amount, timing and/or tax
character of the Portfolio's income and, in turn, of the income distributed to
you.

Derivatives. Each Portfolio is permitted to invest in certain options,
futures and foreign currency contracts. If the Portfolio makes these
investments, it could be required to mark-to-market these contracts and realize
any unrealized gains and losses at its fiscal year end even though it continues
to hold the contracts. Under these rules, gains or losses on the contracts
generally would be treated as 60% long-term and 40% short-term gains or losses,
but gains or losses on certain foreign currency contracts would be treated as
ordinary income or losses. In determining its net income for excise tax
purposes, the Portfolio also would be required to mark-to-market these contracts
annually as of November 30 (for capital gain net income and ordinary income
arising from certain foreign currency contracts), and to realize and distribute
any resulting income and gains.

Securities lending. The Portfolio's entry into securities lending
transactions may cause the replacement income earned on the loaned securities to
fall outside of the definition of qualified dividend income. This replacement
income generally will not be eligible for reduced rates of taxation on qualified
dividend income and, to the extent that debt securities are loaned, will
generally not qualify as qualified interest income for foreign withholding tax
purposes.

Tax straddles. The Portfolio's investment in options, futures and foreign
currency contracts in connection with certain hedging transactions could cause
the Portfolio to hold offsetting positions in securities. If the Portfolio's
risk of loss with respect to specific securities in its portfolio is
substantially diminished by the fact that it holds other securities, the
Portfolio could be deemed to have entered into a tax "straddle" or to hold a
"successor position" that would require any loss realized by it to be deferred
for tax purposes.

Investments in securities of uncertain tax character. The Portfolio may
invest in securities the U.S. Federal income tax treatment of which may not be
clear or may be subject to recharacterization by the IRS. To the extent the tax
treatment of such securities or the income from such securities differs from the
tax treatment expected by the Portfolio, it could affect the timing or character
of income recognized by the Portfolio, requiring the Portfolio to purchase or
sell securities, or otherwise change its portfolio, in order to comply with the
tax rules applicable to regulated investment companies under the Code.

Backup Withholding

By law, the Portfolio must withhold a portion of your taxable
dividends and sales proceeds unless you:

The Portfolio also must withhold if the IRS instructs it to do so. When
withholding is required, the amount will be 28% of any dividends or proceeds
paid. The special U.S. tax certification requirements applicable to non-U.S.
investors are described under the "Non-U.S. Investors" heading below.

Non-U.S. Investors

In general. The United States imposes a flat 30% withholding tax (or a
withholding tax at a lower treaty rate) on U.S. source dividends, including on
income dividends paid to you by the Portfolio, subject to certain exemptions for
dividends designated as capital gain dividends, short-term capital gain
dividends and interest-related dividends as described below. However,
notwithstanding such exemptions from U.S. withholding at the source, any
dividends and distributions of income and capital gains, including the proceeds
from the sale of your Portfolio shares, 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.

Capital gain dividends & short-term capital gain dividends. In general,
capital gain dividends paid by the Portfolio from either long-term or short-term
capital gains (other than gain realized on disposition of U.S. real property
interests) are not subject to U.S. withholding tax unless you are a nonresident
alien individual present in the United States for a period or periods
aggregating 183 days or more during the taxable year.

Interest-related dividends. Also, interest-related dividends paid by the
Portfolio from qualified interest income are not subject to U.S. withholding
tax. "Qualified interest income" includes, in general, U.S. source (1) bank
deposit interest, (2) short-term original discount and (3) interest (including
original issue discount, market discount, or acquisition discount) on an
obligation which is in registered form, unless it is earned on an obligation
issued by a corporation or partnership in which the Portfolio is a 10-percent
shareholder or is contingent interest, and (4) any interest-related dividend
from another regulated investment company. On any payment date, the amount of an
income dividend that is designated by the Portfolio as an interest-related
dividend may be more or less than the amount that is so qualified. This is
because the designation is based on an estimate of the Portfolio's qualified
interest income for its entire fiscal year, which can only be determined with
exactness at fiscal year end. As a consequence, the Portfolio may over withhold
a small amount of U.S. tax from a dividend payment. In this case, the non-U.S.
investor's only recourse may be either to forgo recovery of the excess
withholding, or to file a United States nonresident income tax return to recover
the excess withholding.

Further limitations on tax reporting for interest-related dividends and
short-term capital gain dividends for non-U.S. investors; sunset rule. It may
not be practical in every case for the Portfolio to designate, and the Portfolio
reserves the right in these cases to not designate, small amounts of
interest-related or short-term capital gain dividends. Additionally, the
Portfolio's designation of interest-related or short-term capital gain dividends
may not be passed through to shareholders by intermediaries who have assumed tax
reporting responsibilities for this income in managed or omnibus accounts due to
systems limitations or operational constraints. The exemption from withholding
for short-term capital gain dividends and interest-related dividends paid by the
Portfolio is effective for dividends paid with respect to taxable years of the
Portfolio beginning after December 31, 2004 and before January 1, 2008 unless
such exemptions are extended or made permanent.

Ordinary dividends; effectively connected income. Ordinary dividends paid
by the Portfolio to non-U.S. investors on the income earned on portfolio
investments in (i) the stock of domestic and foreign corporations, and (ii) the
debt of foreign issuers continue to be subject to U.S. withholding tax. If you
hold your Portfolio shares in connection with a U.S. trade or business, your
income and gains will be considered effectively connected income and taxed in
the U.S. on a net basis, in which case you may be required to file a nonresident
U.S. income tax return.

U.S. estate tax. An individual who, at the time of death, is a Non-U.S.
shareholder will nevertheless be subject to U.S. federal estate tax with respect
to shares at the graduated rates applicable to U.S. citizens and residents,
unless a treaty exception applies. In the absence of a treaty, there is a
$13,000 statutory estate tax credit. A partial exemption from U.S. estate tax
may apply to Portfolio shares held by the estate of a nonresident decedent. The
amount treated as exempt is based upon the proportion of the assets held by the
Portfolio at the end of the quarter immediately preceding the decedent's death
that are debt obligations, deposits, or other property that generally would be
treated as situated outside the United States if held directly by the estate.
This provision applies to decedents dying after December 31, 2004 and before
January 1, 2008, unless such provision is extended or made permanent. Transfers
by gift of shares of the Portfolio by a non-U.S. shareholder who is a
nonresident alien individual will not be subject to U.S. federal gift tax. The
tax consequences to a non-U.S. shareholder entitled to claim the benefits of an
applicable tax treaty may be different from those described herein. Non-U.S.

Effect of Future Legislation; Local Tax Considerations

PROXY VOTING POLICIES

The Board of Directors of the Fund has delegated the authority to vote
proxies for the portfolio securities held by the Portfolio to the Advisor in
accordance with the Proxy Voting Policies and Procedures (the "Voting Policies")
and Proxy Voting Guidelines ("Voting Guidelines") adopted by the Advisor.

The Investment Committee at the Advisor is generally responsible for
overseeing the Advisor's proxy voting process. The Investment Committee has
formed a Corporate Governance Committee composed of certain officers, directors
and other personnel of the Advisor and has delegated to its members authority to
(i) oversee the voting of proxies, (ii) make determinations as to how to vote
certain specific proxies, and (iii) verify the on-going compliance with the
Voting Policies. The Corporate Governance Committee may designate one or more of
its members to oversee specific, ongoing compliance with respect to the Voting
Policies and may designate other personnel of the Advisor to vote proxies on
behalf of the Portfolio, including all authorized traders of the Advisor.

The Advisor votes (or refrains from voting) proxies in a manner consistent
with the best interests of the Portfolio as understood by the Advisor at the
time of the vote. Generally, the Advisor analyzes proxy statements on behalf of
the Portfolio in accordance with the Voting Policies and the Voting Guidelines.
Most proxies that the Advisor receives will be voted in accordance with the
Voting Guidelines. Since most proxies are voted in accordance with the Voting
Guidelines, it normally will not be necessary for the Advisor to make an actual
determination of how to vote a particular proxy, thereby largely eliminating
conflicts of interest for the Advisor during the proxy voting process. However,
the Proxy Policies do address the procedures to be followed if a conflict of
interest arises between the interests of the Portfolio, and the interests of the
Advisor or its affiliates. If the Corporate Governance Committee member has
actual knowledge of a conflict of interest and recommends a vote contrary to the
Voting Guidelines, the Advisor, prior to voting, will fully disclose the
conflict to the Board of Directors of the Fund, or an authorized committee of
the Board, and vote the proxy in accordance with the direction of the Board or
its authorized committee.

The Advisor will usually vote proxies in accordance with the Voting
Guidelines. The Voting Guidelines provide a framework for analysis and decision
making, however, the Voting Guidelines do not address all potential issues. In
order to be able to address all the relevant facts and circumstances related to
a proxy vote, the Advisor reserves the right to vote counter to the Voting
Guidelines if, after a review of the matter, the Advisor believes that the best
interests of the Portfolio would be served by such a vote. In such a
circumstance, the analysis will be documented in writing and periodically
presented to the Corporate Governance Committee. To the extent that the Voting
Guidelines do not cover potential voting issues, the Advisor will vote on such
issues in a manner that is consistent with the spirit of the Voting Guidelines
and that the Advisor believes would be in the best interests of the Portfolio.

Examples of some of the Voting Guidelines are described below. Under the
Voting Guidelines, proxies will usually be voted for: (i) the ratification of
independent auditors (ii) the elimination of anti-takeover measures; and (iii)
re-incorporation when the economic factors outweigh any negative governance
changes. Pursuant to the Voting Guidelines proxies will usually be voted
against: (i) the institution of anti-takeover measures (such as the institution
of classified boards of directors and the creation of super majority provisions)
and (ii) proposals authorizing the creation of new classes of preferred stock
with unspecified voting, conversion, dividend distribution and other rights. The
Voting Guidelines also provide that certain proposals will be considered on a
case-by-case basis, including: (i) mergers and acquisitions, which will be
assessed to determine whether the transaction enhances shareholder value; (ii)
proposals with respect to management compensation plans; (iii) proposals
increasing the authorized common stock of a company and (iv) proposals with
respect to the composition of a company's Board of Directors. The Advisor may,
but will not ordinarily, take social concerns into account in voting proxies
with respect to securities held by the Portfolio.

The Advisor votes (or refrains from voting) proxies in a manner that the
Advisor determines is in the best interests of the Portfolio and which seeks to
maximize the value of the Portfolio's investments. In some cases, the Advisor
may determine that it is in the best interests of the Portfolio to refrain from
exercising proxy voting rights. The Advisor may determine that voting is not in
the best interest of the Portfolio and refrain from voting if the costs,
including the opportunity costs, of voting would, in the view of the Advisor,
exceed the expected benefits of voting. For securities on loan, the Advisor will
balance the revenue-producing value of loans against the difficult-to-assess
value of casting votes. It is the Advisor's belief that the expected value of
casting a vote generally will be less than the securities lending income, either
because the votes will not have significant economic consequences or because the
outcome of the vote would not be affected by the Advisor recalling loaned
securities in order to ensure they are voted. The Advisor does intend to recall
securities on loan if it determines that voting the securities is likely to
materially affect the value of the Portfolio's investment and that it is in the
Portfolio's best interests to do so. In cases where the Advisor does not receive
a solicitation or enough information within a sufficient time (as reasonably
determined by the Advisor) prior to the proxy-voting deadline, the Advisor may
be unable to vote.

With respect to non-U.S. securities, it is typically both difficult and
costly to vote proxies due to local restrictions, customs, and other
requirements or restrictions. The Advisor does not vote proxies of non-U.S.
companies if the Advisor determines that the expected economic costs from voting
outweigh the anticipated economic benefit to the Portfolio associated with
voting. The Advisor determines whether to vote proxies of non-U.S. companies on
a portfolio-by-portfolio basis, and generally implements uniform voting
procedures for all proxies of a country. The Advisor periodically reviews voting
logistics, including costs and other voting difficulties, on a portfolio by
portfolio and country by country basis, in order to determine if there have been
any material changes that would affect the Advisor's decision of whether or not
to vote.

Information regarding how the Portfolio voted proxies related to its
portfolio securities during the 12 month period ended June 30 of each year is
available, no later than August 31 of each year, without charge, (i) upon
request, by calling collect: (310) 395-8005 or (ii) on the Advisor's web site at
http://www.dfaus.com and (iii) on the Commission's web site at
http://www.sec.gov.

DISCLOSURE OF PORTFOLIO HOLDINGS

The Advisor and the Board of Directors of the Fund have adopted a policy
(the "Policy") to govern disclosure of the portfolio holdings of the Portfolio
("Holdings Information"), and to prevent the misuse of material non-public
Holdings Information. The Advisor has determined that the Policy and its
procedures: (1) are reasonably designed to ensure that disclosure of Holdings
Information is in the best interests of the shareholders of the Portfolio, and
(2) appropriately address the potential for material conflicts of interest.

Online Disclosure of Portfolio Holdings Information. The Portfolio
generally discloses up to its twenty-five largest portfolio holdings and the
percentages that each of these largest portfolio holdings represent of the
Portfolio's total assets ("largest holdings"), as of the most recent month-end,
online at the Advisor's public web site, http://www.dfaus.com, within twenty
days after the end of each month. This online disclosure may also include
information regarding the Portfolio's industry allocations. The Portfolio
generally discloses its complete Holdings Information (other than cash and cash
equivalents), as of month-end, online at the Advisor's public web site,
http://www.dfaus.com, three months following the month-end.

Disclosure of Holdings Information to Recipients. Each of the Advisor's
Chairman, Director of Institutional Services, Head of Portfolio Management and
Trading and General Counsel (together, the "Designated Persons") may authorize
disclosing non-public Holdings Information more frequently or at different
periods than as described above solely to those financial advisors, registered
accountholders, authorized consultants, authorized custodians, or third-party
data service providers (each a "Recipient") who: (i) specifically request the
more current non-public Holdings Information, and (ii) execute a Use and
Nondisclosure Agreement (each a "Nondisclosure Agreement"). Each Nondisclosure
Agreement subjects the Recipient to a duty of confidentiality with respect to
the non-public Holdings Information, and prohibits the Recipient from trading
based on the non-public Holdings Information. Any non-public Holdings
Information that is disclosed shall not include any material information about
the Portfolio's trading strategies or pending portfolio transactions. The
non-public Holdings Information provided to a Recipient under a Nondisclosure
Agreement, unless indicated otherwise, is not subject to a time delay before
dissemination.

As of the date of this SAI, the Advisor and the Portfolios had ongoing
arrangements with the following Recipients to make available non-public Holdings
Information:

Recipient Business Purpose Frequency
---------------------------- --------------------------------------------- ---------------------------
PFPC Trust Company Fund Domestic Custodian Daily
---------------------------- --------------------------------------------- ---------------------------
Citibank, N.A. Fund Global Custodian and middle office Daily

PFPC Inc. Fund Administrator, Accounting Agent and Daily
Transfer Agent
---------------------------- --------------------------------------------- ---------------------------
PricewaterhouseCoopers LLP Independent registered public accounting Semi-annually (based on
firm fiscal year)

In addition, certain employees of the Advisor and its subsidiaries receive
Holdings Information on a quarterly, monthly, or daily basis, or upon request,
in order to perform their business functions. None of the Portfolio, the
Advisor, or any other party receives any compensation in connection with these
arrangements.

The Policy includes the following procedures to ensure that disclosure of
Holdings Information is in the best interests of shareholders, and to address
any conflicts between the interests of shareholders, on the one hand, and the
interests of the Advisor, DFAS, or any affiliated person of the Fund, the
Advisor, or DFAS, on the other. In order to protect the interests of
shareholders and the Portfolio, and to ensure no adverse effect on shareholders
in the limited circumstances where a Designated Person is considering making
non-public Holdings Information available to a Recipient, the Advisor's Director
of Institutional Services and the Chief Compliance Officer will consider any
conflicts of interest. If the Chief Compliance Officer, following appropriate
due diligence, determines that: (1) the Portfolio has a legitimate business
purpose for providing the non-public Holdings Information to a Recipient, and
(2) disclosure of non-public Holdings Information to the Recipient would be in
the best interests of shareholders and will not adversely affect the
shareholders, then the Chief Compliance Officer may approve the proposed
disclosure.

The Policy prohibits the Portfolio, the Advisor, or an affiliate thereof
from receiving any compensation or other consideration of any type for the
purpose of obtaining disclosure of non-public Holdings Information or other
investment positions. "Consideration" includes any agreement to maintain assets
in the Portfolio or in other investment companies or accounts managed by the
Advisor or by any affiliated person of the Advisor.

The Policy and its procedures are intended to provide useful information
concerning the Portfolio to existing and prospective shareholders, while at the
same time preventing the improper use of Holdings Information. However, there
can be no assurance that the furnishing of any Holdings Information is not
susceptible to inappropriate uses, particularly in the hands of sophisticated
investors, or that the Holdings Information will not in fact be misused in other
ways, beyond the control of the Advisor.

FINANCIAL STATEMENTS

PricewaterhouseCoopers LLP, Two Commerce Square, Suite 1700, 2001 Market
Street, Philadelphia, PA 19103-7042, is the Fund's independent registered public
accounting firm. It audits the Fund's annual financial statements. Because the
Portfolio had not commenced operations as of November 30, 2006, the annual
reports of the Fund for the fiscal year ended November 30, 2006 do not contain
any data regarding the Portfolio.

PERFORMANCE DATA

The Portfolio may compare its investment performance to appropriate market
and mutual fund indices and investments for which reliable performance data is
available. Such indices are generally unmanaged and are prepared by entities and
organizations that track the performance of investment companies or investment
advisors. Unmanaged indices often do not reflect deductions for administrative
and management costs and expenses. The performance of the Portfolio may also be
compared in publications to averages, performance rankings, or other information
prepared by recognized mutual fund statistical services. Any performance
information, whether related to the Portfolio or to the Advisor, should be
considered in light of the Portfolio's investment objectives and policies,
characteristics and the quality of the portfolio and market conditions during
the time period indicated and should not be considered to be representative of
what may be achieved in the future.
